    ABSTRACT: Drug resistance currently represents a daunting challenge in the treatment of breast cancer patients. With an increased understanding of the underlying mechanisms of drug resistance, the role of extracellular vesicles (EVs) in the development of chemo-insensitivity attracts extensive attention. EVs are membrane-limited, cell type-dependent vesicles that are secreted by normal or malignant cells. EVs comprise various types of contents, including genetic cargoes, proteins, and specific lipids. The characteristics of the contents determine their specific functions in not only physiological but also pathological conditions. It has been demonstrated that miRNAs and proteins in EVs are strongly correlated with breast cancer drug resistance. Additionally, they may exert an influence on de novo and acquired resistance bioprocesses. With the advances in extraction and detection technologies, EVs have also been employed to precisely diagnose and predict the outcome of therapy in breast cancer. On the other hand, they can also be exploited as efficient delivery system in future anticancer applications. In this paper, we summarized relative mechanisms concerning the relationship between EVs and breast cancer drug resistance, and then, we provide up-to-date research advances in the clinical application of EVs.

    ABSTRACT: NDRG4 is a novel candidate tumor suppressor and can inhibit PI3K/AKT signal which is related with energy balance and related carcinogenesis. In the present study, we investigated whether NDRG4 status could modify the association of obesity with clinical outcome of colorectal cancer. For this purpose, a hospital-based prospective study cohort of 226 colorectal cancer patients was involved. NDRG4 mRNA levels were determined by real-time PCR. Association of NDRG4 mRNA expression with disease-free and overall survival was studied first. Then, the association of obesity with clinical outcome was determined according to NDRG4 level. Multivariate Cox proportional hazards model was used to compute hazard ratio, adjusting for covariates including microsatellite instability, KRAS, BRAF and PIK3CA mutation. Results showed that NDRG4 mRNA expression was decreased in tumor specimens and significantly correlated with tumor differentiation, invasion and metastasis. Patients with tumor of reduced NDRG4 mRNA level had unfavorable disease-free and overall survival. Obesity was found to be adversely associated with disease-free and overall survival in tumors with reduced NDRG4 level, not in preserved NDRG4 level group, in both univariate and multivariate analysis. These data provided the first evidence that NDRG4 level in colorectal cancer could effectively stratify the prognostic value of obesity, which would better the understanding of the prognostic role of obesity in colorectal cancer. Our results also support the notion that the host-tumor interactions in colorectal cancer might influence tumor aggressiveness.

    ABSTRACT: Long noncoding RNAs (lncRNAs) have recently been identified to be involved in various diseases including cancer. NEAT1 is a recently identified lncRNA with its function largely unknown in human malignancy. In the present study, we investigated NEAT1 expression in 239 cases of clinical colorectal cancer specimens and matched normal tissues. Statistical methods were utilized to analyze the association of NEAT1 with clinical features, disease-free and overall survival of patients. Results showed that NEAT1 expression in colorectal cancer was up-regulated in 72.0% (172/239) cases compared with corresponding normal counterparts, and related to tumor differentiation, invasion, metastasis and TNM stage. Kaplan-Meier analysis proved that NEAT1 was associated with both disease-free survival and overall survival of patients with colorectal cancer that patients with high NEAT1 expression tend to have unfavorable outcome. Moreover, cox's proportional hazards analysis showed that high NEAT1 expression was an independent prognostic marker of poor outcome. These results provided the first evidence that the expression of NEAT1 in colorectal cancer may play an oncogenic role in colorectal cancer differentiation, invasion and metastasis. It also proved that NEAT1 may serve as an indicator of tumor recurrence and prognosis of colorectal cancer.

    ABSTRACT: Background The aim of this study was to compare surgical outcomes and oncologic efficacy of laparoscopy-assisted gastrectomy (LAG) versus open gastrectomy(OG) for advanced gastric cancer. Methods For this study, eighty-seven consecutive AGC patients underwent LAG with D2 lymph node dissection between April 2005 to October 2009 were enrolled, compared with eighty-seven AGC patients underwent OG during the same period. Results Operative procedure and surgical margin were similar between two groups. The operative time was significantly longer in LAG group than OG group, while the estimated blood loss was significantly less in LAG group. There were no significant differences in postoperative complications and in the number of lymph nodes retrieved. The use of analgesic drugs was significantly less after LAG. Length of postoperative stay was significantly shorter in LAG group. The 5-year overall survival rate and recurrence-free survival rate were comparative between two groups. Conclusions This 5-year case-control study presented that laparoscopy-assisted gastrectomy may be a safe and acceptable procedure in terms of long-term results for advanced gastric cancer.

    ABSTRACT: MicroRNAs are noncoding RNAs that regulate multiple cellular processes during cancer progression. Among various microRNAs, miR-630 has recently been identified to be implicated in many critical processes in human malignancies. We investigated the expression pattern and prognostic value of miR-630 in human colorectal cancer by utilizing cancer and adjacent normal specimens from 206 patients. Quantitative real-time PCR assay was used to detect the expression of miR-630, and appropriate statistical analysis was used to evaluate the association of miR-630 with overall survival. It was found that miR-630 expression was significantly increased in colorectal cancer specimens compared with that in adjacent normal specimens. It was also proved that miR-630 expression in colorectal cancer was associated with tumor invasion, lymph node metastasis, distant metastasis, and tumor-node-metastasis (TNM) stage. The Kaplan-Meier survival analysis proved that increased miR-630 expression was associated with poor overall survival of patients with colorectal cancer. Multivariate analysis proved that miR-630 was an independent prognostic marker after adjusted for known prognostic factors. These results confirmed the overexpression of miR-630 in human colorectal cancer and its association with tumor progression. It also suggested that miR-630 expression might serve as a prognostic biomarker for patients with colorectal cancer.

    ABSTRACT: CD147 is correlated with tumor aggressiveness in various human malignancies. Here, we investigated CD147 protein expression in 223 patients with gastric cancer by immunohistochemistry and analyzed its association with disease-free and overall survival. CD147 was increased in gastric cancer compared to normal tissues. Additionally, CD147 expression was associated with gastric cancer invasion, metastasis and TNM stage, whereas it was not related to age, sex, differentiation status, tumor site or Lauren classification. Kaplan-Meier analysis confirmed that CD147 was associated with disease-free and overall survival in patients with gastric cancer; i.e., patients with positive CD147 staining tend to have worse disease-free and overall survival. Moreover, Cox's proportional hazards analysis demonstrated that CD147 was an independent marker of disease-free and overall survival for patients with gastric cancer. These results confirm the association of CD147 with gastric cancer invasion and metastasis and prove that CD147 might be an indicator of tumor recurrence and prognosis in gastric cancer.

    ABSTRACT: Human leukocyte antigen G (HLA-G) is a non-classical HLA class I molecule thought to play a key role in maternal-fetal tolerance and cancer immune evasion. This study aimed to investigate the HLA-G expression in lesion sections and plasma sHLA-G levels of primary esophageal squamous cell carcinoma (ESCC) patients and its clinical significance in diagnosis and prognosis of ESCC. 60 ESCC patients and 28 healthy controls were recruited, and the positive expression of HLA-G in ESCC lesions and adjacent normal tissues were 70% (42/60) and 8.6% (5/60) (P<0.05), respectively, while no expression was found in normal controls. HLA-G1 and HLA-G5 were determined to be dominating isoforms measured by RT-PCR. There was a significant difference in plasma sHLA-G levels between patients with ESCC (15.04U/ml, range 4.33-250.00U/ml) and healthy controls (6.81U/ml, range 0-29.27U/ml) (P<0.01). The plasma IL-10 level was higher in ESCC patients than the controls (23.86pg/ml vs. 12.81pg/ml, P<0.01). HLA-G expression in lesion tissues was correlated with cancer cell differentiation (P=0.033), lymph node metastasis (P=0.035) of ESCC. However, no obvious correlations were demonstrated between the plasma sHLA-G levels and the clinicopathological parameters. There was a significant correlation between sHLA-G and IL-10 expression (r=0.353, P=0.006) in patients with Esophageal squamous cell carcinoma. HLA-G positive expression showed poorer prognosis of ESCC. HLA-G positive expression might serve as a potential marker in the diagnosis or prediction of ESCC.

    ABSTRACT: This article reports on the prevalence of noncommunicable diseases (NCDs) and their risk factors in the city of Guangzhou, China, and shows a trend toward epidemic proportions when municipal data are compared with provincial data. We conducted the Guangzhou Community Health Survey in the 12 administrative districts of Guangzhou to learn about NCDs and their risk factors. A community-based, face-to-face survey with a stratified multistage cluster sampling was used. Information was gathered on 27,743 respondents, aged 0 to 108 years, with a male to female ratio of 1 to 1. All participants completed a questionnaire, and those aged 15 years or older had a physical examination. Survey results were compared with the provincial results of the 2002 Guangdong Nutrition and Health Survey (GNHS). The data were weighted to the respondent's probability of selection and to the age- and sex-specific population. Prevalence estimate of self-reported NCDs was 16.0%. Hypertension and diabetes were reported as the most important NCDs. Of those who responded, 6.8% reported having more than 2 chronic conditions. The adjusted prevalence of hypertension decreased by 13.3% since 2002. Awareness, treatment, and control of hypertension and diabetes were improved. The estimated prevalence of current smoking decreased, and the prevalence of former smoking increased from 2002. However, the prevalence of overweight and obesity, especially central obesity, increased. Results were encouraging with regard to hypertension and diabetes. However, the unfavorable trends, especially for overweight, central obesity, and passive smoking, call for additional action.

    ABSTRACT: MicroRNAs are noncoding RNAs that regulate multiple cellular processes during cancer progression. Among various microRNAs, MiR-630 has recently been identified to be implicated in many critical processes in human malignancies. We aimed to investigate the significance and prognostic value of miR-630 in human gastric cancer. Gastric cancer and adjacent normal specimens from 236 patients from who had not received neoadjuvant chemotherapy were collected. The expression of miR-630 was investigated by quantitative real-time PCR assay and its association with overall survival of patients was analyzed by statistical analysis. MiR-630 expression level was significantly elevated in gastric cancer in comparison to adjacent normal specimens. It is also proved that miR-630 expression was to be associated with gastric cancer invasion, lymph node metastasis, distant metastasis and TNM stage. In addition, survival analysis proved that elevated miR-630 expression was associated with poor overall survival of patients. Multivariate survival analysis also proved that miR-630 was an independent prognostic marker after adjusted for known prognostic factors. The present study proved the over-expression of miR-630 and its association with tumor progression in human gastric cancer. It also provided the first evidence that miR-630 expression was an independent prognostic factor for patients with gastric cancer, which might be a potential valuable biomarker for gastric cancer.

    ABSTRACT: An increasing amount of evidence demonstrated that the neurotrophic receptor tropomyosin-related kinase B (TrkB) plays a critical role in the development and progression of multiple types of cancer. However, its underlying mechanism in distant metastasis through the circulatory and lymphatic systems in colorectal cancer (CRC) is still unclear. Here we showed that downregulation of TrkB using short hairpin RNA obviously increased anoikis (detachment-induced apoptosis resulting from loss of cell-matrix interactions) sensitivity of CRC cells in vitro. Furthermore, using tail vein injection model, we confirmed that silencing TrkB significantly inhibited metastasis of CRC cells in vivo. Conversely, overexpression of TrkB obviously protected CRC cells from anoikis in vitro. Both loss- and gain-of-functional experiments indicated that TrkB could be a functional molecule in anti-anoikis of CRC cells. Mechanistically, we found that protein kinase B (PKB, also known as Akt) signaling pathway was a functional link in TrkB-induced anoikis suppression in CRC cells. Phosphorylation levels of Akt are closely related with the expression pattern of TrkB in CRC cells and inhibition of Akt activation robustly induces anoikis of CRC cells in vitro. In addition, our clinical investigation showed that high TrkB expression levels in CRC patients were associated with lymph node metastasis, distant metastasis and unfavourable prognosis. Thus, based on our results, this study suggests that an important function of TrkB is to protect CRC cells from anoikis in the circulatory and lymphatic systems, and that TrkB could be a promising candidate in CRC therapy, especially in the inhibition of cancer metastasis.

    ABSTRACT: Background Matrix metalloproteinase-14 (MMP-14) has been considered to play an important role in invasion and metastasis of human solid tumor. Aim The present study aimed to investigate the association of MMP-14 with overall survival in human gastric cancer. Methods Gastric cancer and adjacent normal specimens were collected from 205 patients who had not received neoadjuvant chemotherapy. MMP-14 expression was investigated by immunohistochemistry assay and staining evaluation results were analyzed statistically in relation to overall survival of patients. Results MMP-14 expression proved to be increased in gastric cancer compared with that in normal tissues. It was also proved that MMP-14 expression was associated with tumor invasion, metastasis, and TNM stage while no correlations were detected between MMP-14 expression and age, sex, differentiation status, or Lauren’s classification. Moreover, patients with gastric cancer of MMP-14-positive expression tend to have worse overall survival compared with those with MMP-14 negative expression. Conclusions The present study confirmed the over-expression of MMP-14 in human gastric cancer and its association with tumor progression. It also provided the first evidence that MMP-14 expression in gastric cancer was an independent negative prognostic factor of patients.

    ABSTRACT: Background After laparoscopic total gastrectomy, the optimal method for esophagojejunostomy remains to be established. Study Design Between June 2009 and December 2012, 52 patients with gastric cancer underwent consecutive laparoscopic total gastrectomy with a new self-pulling and holding purse-string suture technique using a circular stapler for intracorporeal circular-stapled esophagojejunostomy in our hospital. Hand suture of purse-string is performed with assistance of constant self-pulling and holding of uncut the right esophagus on transected esophageal end after subtotal circumferential transaction (90%) of distal esophagus. needle insertion from the serosal side or the mucosal side of esophageal lumen is chosen depending on the difficulty of laparoscopic suturing to avoid backhand stitch. Results No procedures were converted to open or other laparoscopic anastomosis techniques in 52 cases. The mean operating time was 297.1 ± 53.0 min, and the time of both for the purse-string suture and anvil placement was 18.3 ±6.1 min. Negative tumor margin involved in all of 52 cases, and the mean proximal esophageal margin was 5.3 ± 1.7cm. There were 3 major postoperative complications: one patient for anastomotic bleeding on postoperative day 1 recovered in the conservative precedure, two patients for intestinal obstruction due to the adhesion and angulation at the jejunojejunal anastomosis recovered after enterolysis. Total morbidity rate was 21.2% , and there was no mortality. There were no postoperative anastomotic leakage, stenosis and duodenal stump leakage observed during the median follow-up period of 17 months ( range 7-43months ). Conclusions We believe that this method is feasible and reliable, and it could be applied in most laparoscopic total gastrectomy procedures. However, further follow-up is necessary to confirm long-term outcomes.

    ABSTRACT: Acute lung injury (ALI) is still a leading cause of morbidity and mortality in critically ill patients. Recently, our and other studies have found that hydrogen gas (H₂) treatment can ameliorate the lung injury induced by sepsis, ventilator, hyperoxia, and ischemia-reperfusion. However, the molecular mechanisms by which H₂ ameliorates lung injury remain unclear. In the current study, we investigated whether H₂ or hydrogen-rich saline (HS) could exert protective effects in a mouse model of ALI induced by intratracheal administration of lipopolysaccharide (LPS) via inhibiting the nuclear factor κB (NF-κB) signaling pathway-mediated inflammation and apoptosis. Two percent of H₂ was inhaled for 1 h beginning at 1 and 6 h after LPS administration, respectively. We found that LPS-challenged mice exhibited significant lung injury characterized by the deterioration of histopathology and histologic scores, wet-to-dry weight ratio, and oxygenation index (PaO₂/FIO₂), as well as total protein in the bronchoalveolar lavage fluid (BALF), which was attenuated by H₂ treatment. Hydrogen gas treatment inhibited LPS-induced pulmonary early and late NF-κB activation. Moreover, H₂ treatment dramatically prevented the LPS-induced pulmonary cell apoptosis in LPS-challenged mice, as reflected by the decrease in TUNEL (deoxynucleotidyl transferase dUTP nick end labeling) staining-positive cells and caspase 3 activity. Furthermore, H₂ treatment markedly attenuated LPS-induced lung neutrophil recruitment and inflammation, as evidenced by downregulation of lung myeloperoxidase activity, total cells, and polymorphonuclear neutrophils in BALF, as well as proinflammatory cytokines (tumor necrosis factor α, interleukin 1β, interleukin 6, and high-mobility group box 1) and chemokines (keratinocyte-derived chemokine, macrophage inflammatory protein [MIP] 1α, MIP-2, and monocyte chemoattractant protein 1) in BALF. In addition, i.p. injection of 10 mL/kg hydrogen-rich saline also significantly attenuated the LPS-induced ALI. Collectively, these results demonstrate that molecular hydrogen treatment ameliorates LPS-induced ALI through reducing lung inflammation and apoptosis, which may be associated with the decreased NF-κB activity. Hydrogen gas may be useful as a novel therapy to treat ALI. munosorbent assay; H₂-hydrogen gas; HMGB1-high-mobility group box 1; HS-hydrogen-rich saline; i.t.-intratracheal; KC-keratinocyte-derived chemokine; LPS-lipopolysaccharide; MCP-1-monocyte chemoattractant protein 1; MIP-1α-macrophage inflammatory protein 1α; MIP-2-macrophage inflammatory protein 2; MPO-myeloperoxidase; PBS-phosphate-buffered saline; PMNs-polymorphonuclear neutrophils; TUNEL-deoxynucleotidyl transferase dUTP nick end labeling; W/D-wet-to-dry.

    ABSTRACT: Totally laparoscopic gastrectomy represents the evolution of laparoscopy-assisted gastrectomy. Most surgeons prefer laparoscopy-assisted gastrectomy rather than totally laparoscopic procedures because of technical difficulties of intracorporeal anastomosis. We created one novel stapling anastomosis without hand-sewn technique in totally laparoscopic Billroth II gastrectomy. The feasibility and early surgical outcomes of totally laparoscopic Billroth II gastrectomy with stapling anastomosis and with hand-sewn anastomosis were introduced in this study. We retrospectively analyzed early surgical outcomes in 70 patients who underwent totally laparoscopic Billroth II distal gastrectomy for gastric cancer between January 2010 and July 2011. The patients were divided into hand-sewn and device groups according to whether intracorporeal anastomosis was performed by only hand-sewn technique (n = 36) or only stapling devices (n = 34). In the device group, the gastrojejunostomy was performed using a circular stapler, and an additional side-to-side jejunojejunostomy was made at the site of jejunal enterotomy. There was no difference in the mean number of lymph nodes retrieved in both groups. The blood loss (hand-sewn group 205.8 ± 37.4 vs. device group 201.2 ± 51.2 ml, p > 0.05) and hospital stay (hand-sewn group 6.5 ± 3.7 vs. device group 5.9 ± 4.1 days, p > 0.05) were similar in both groups. We found that intracorporeal anastomosis by totally stapling devices was associated with decreased operative time (hand-sewn group 239.0 ± 40.1 vs. device group 203.6 ± 27.9 min, p < 0.05). We suggest that intracorporeal anastomosis using only stapling devices in the described method was as safe and feasible as by hand-sewn technique. Moreover, it is a simple and time-saving method without any difficult hand-sewn procedures.

    ABSTRACT: The expression of matrix metalloproteinase-21 (MMP-21) has been shown to be elevated in some solid tumor and thought to enhance tumor invasion and metastasis ability. In the present study, we investigated the expression of MMP-21 and its association with prognosis in stage II and III colorectal cancer. MMP-21 expression was investigated in 286 cases of colorectal cancer by immunohistochemistry assay. Statistical analysis was utilized to evaluate the association of MMP-21 expression with clinicopathological characters and overall survival of patients with stage II and III colorectal cancer. MMP-21 expression was significantly higher in colorectal cancer, compared with that in normal epithelial tissue. And it also correlated with tumor invasion, lymph node metastasis, and distant metastasis of colorectal cancer. MMP-21 was also proved to be an independent prognostic factor in patients with stage II as well as stage III colorectal cancer. However, no correlations between MMP-21 expression and patients' age, sex, tumor location, or differentiation status were detected. These results suggested the potential role of MMP-21 in the invasion and metastasis process of human colorectal cancer. It could also be a novel molecular marker to predict prognosis of patients with stage II and stage III colorectal cancer.

    ABSTRACT: Notch1 has been proven to be aberrantly expressed in colorectal cancer and related to tumor differentiation status. However, few previous studies concentrated on the predictive role of Notch1 expression on the overall survival of patients with colorectal cancer. This study explored expression of Notch1 and its relationship with p65 and prognosis in colorectal cancer. Two independent study cohorts were involved in the present study. Clinical specimens from 941 eligible patients were constructed into tissue microarrays. The expression of Notch1 and p65 protein was investigated by immunohistochemistry. Statistically significant positive correlations were found between protein expression of Notch1 and p65 in both retrospective and prospective study cohorts. Patients with higher Notch1 expression showed a trend of having shorter survival time, whereas patients with lower Notch1 expression had better survival in both study cohorts. In multivariate analysis, Notch1 expression was proven to be an independent predictor of prognosis. Moreover, the prognostic value of Notch1 might differ according to p65 status. Notch1 is an independent predictor of prognosis for patients with colorectal cancer. In addition, the predictive role of Notch1 on clinical outcome might be modified by p65 status, suggesting that targeting Notch1 and nuclear factor κB (NF-κB) might be a promising strategy for colorectal cancer treatment.

    ABSTRACT: Matrix metalloproteinase-21 (MMP-21) is a member of the MMP family, which is overexpressed in some solid tumors and is thought to enhance the tumor invasion and metastasis ability. The aim of the present study is to examine the MMP-21 expression in human colorectal cancer and normal colorectal tissue using tissue microarray technique and to determine its association with clinicopathological characteristics and prognostic value. Four array blocks including 256 cases of colorectal cancer and adjacent normal tissues were investigated by immunohistochemistry assay. Staining evaluation results were analyzed statistically in relation to various clinicopathological characters and overall survival. High level of MMP-21 expression was detected in colorectal cancer, significantly more than in normal colorectal epithelial cells. In colorectal cancer, MMP-21 was significantly positively correlated with depth of invasion, lymph node metastasis, and distant metastasis. The overall survival rate was significantly lower for patients with MMP-21 positive than those with MMP-21 negative tumors. However, no correlations between MMP-21 expression and patients' age, sex tumor location, or differentiation status were detected. Our findings emphasize the important role of MMP-21 in the invasion and metastasis process in human colorectal cancer. It might also serve as a novel prognostic marker that is independent of, and additive to, the TNM staging system.

    ABSTRACT: Matrix metalloproteinase-9 is a member of the MMP family, which is overexpressed in some solid tumors and is thought to enhance tumor invasion and metastasis ability. The present study aims to examine MMP-9 expression in human colorectal cancer and to determine its association with clinicopathological characteristics and prognosis. Colorectal cancer and adjacent normal tissues from 192 patients were investigated by immunohistochemical assay. Staining evaluation results were analyzed statistically in relation to various clinicopathological characters, disease-free survival, and overall survival. High level of MMP-9 expression was detected in colorectal cancer, significantly more than in normal colorectal epithelial cells. In colorectal cancer, MMP-9 was significantly positively correlated with depth of invasion, lymph node metastasis, and distant metastasis. However, no correlations between MMP-9 expression and patient age, sex, tumor location or differentiation status were detected. Disease-free and overall survival were significantly poorer for patients with positive MMP-9 staining than for those with MMP-9-negative tumors. Our findings emphasize the important role of MMP-9 in the invasion and metastasis process in human colorectal cancer. It could also serve as a novel prognostic marker that is independent of, and additive to, the tumor-node-metastasis (TNM) staging system.

    ABSTRACT: Recently, hydrogen gas (H₂) is reported to be a new therapeutic agent in organ damage induced by ischemia-reperfusion (I/R). The present study was designed to investigate the beneficial effects of H₂ against spinal cord I/R injury and its associated mechanisms. Spinal cord ischemia was induced by infrarenal aortic occlusion for 20 min in male New Zealand white rabbits. Treatment with 1%, 2% or 4% H₂ inhalation was given from 10 min before reperfusion to 60 min after reperfusion (total 70 min). Here, we found that I/R-challenged animals showed significant spinal cord damage characterized by the decreased numbers of normal motor neurons and hind-limb motor dysfunction, which was significantly improved by 2% and 4 % H₂ treatment. Furthermore, we found that the beneficial effects of H₂ treatment against spinal cord I/R injury were associated with the decreased levels of oxidative products [8-iso-prostaglandin F2α (8-iso-PGF2α) and malondialdehyde (MDA)] and pro-inflammatory cytokines [tumor necrosis factor-alpha (TNF-α) and high-mobility group box 1 (HMGB1)], as well as increased activities of antioxidant enzymes [superoxide dismutase (SOD) and catalase (CAT)] in serum and spinal cord. In addition, H₂ treatment reduced motor neuron apoptosis in the spinal cord of this model. Thus, H₂ inhalation may be an effective therapeutic strategy for spinal cord I/R damage.
