    ABSTRACT: Objective The present study was performed to test the predictive value of different cut-off points of anthropometric parameters for the presence of type 2 diabetes (T2DM) or glucose tolerance abnormalities in north-east Chinese adults. Design Multistage random cluster sampling method in a cross-sectional study. Setting Height, body weight, maximal body weight in the past, waist and hip circumferences, blood pressure, 2 h post-load glucose and other lifestyle factors were measured. Subjects We used data from 1058 adults aged 20 years or over, selected in the city of Mudanjiang, in 2005. Results BMI, maximal BMI in the past (MAXBMI), waist:hip ratio (WHR), waist:height ratio (WHtR) and waist circumference (WC) were significantly correlated with each other. Partial correlation coefficients between WHtR and WC, and between MAXBMI and BMI, were higher than those between the other indices. The association of anthropometric indices with T2DM or glucose tolerance abnormalities was significantly highest for the collaboration cut-off points of MAXBMI (≥23·0 kg/m 2 for T2DM, ≥22·0 kg/m 2 for glucose tolerance abnormalities) with WHtR (≥0·52). Areas under the receiver-operating characteristic curves also showed that WHtR was a better anthropometric index that discriminated between the presence and absence of T2DM and an excellent indicator with high Youden’s index. Conclusions MAXBMI combined with WHtR was a better anthropometric index associated with T2DM or glucose tolerance abnormalities. The combined use of these two measures is a good choice for T2DM prevention and screening.

    ABSTRACT: To investigate the relationship and the influence between pre-diabetes mellitus (PDM) and hyperuricemia (HUA). 157 PDM patients, aged 20 to 75 years old were selected from the Second Clinical Medical College of Harbin Medical University, from 2009 February to 2010 February and were divided into HUA group (76 cases) and NUA group (81 cases). All the patients had not been on thiazide drugs. T-test and Pearson correlation analysis were used to calculate the differences and correlation between uric acid and biochemical indicators. In the HUA group,BMI was (27.74±2.88 ) kg/m(2), waist to height ratio (WSR) was(0.55 ± 0.41), TC was (6.61 ± 0.73) mmol/L, TG was(3.94 ± 1.97) mmol/L, LDL-C was (3.60 ± 0.45) mmol/L and homeostasis model assessment-insulin resistance index (HOMA-IR) was (3.09 ± 1.20). There were significant differences noticed in BMI, TG, TC, LDL-C, HOMA-IR at higher level in the HUA group than those in the NUA group. Pre-diabetes uric acid levels were positively correlated with TG, TC, LDL-C while HOMA-IR(TG:r = 0.29, TC:r = 0.33,LDL-C:r = 0.49, HOMA-IR:r = 0.51, P < 0.05) was negatively correlated (r = -0.30, P < 0.05)with the HbA1c. The levels of PDM uric acid might both be related with TC, TG, LDL-C and HOMA-IR. The High level of uric acid status in vivo appeared closely related to HOMA-IR, which could further promote the progress of pre-diabetic patients to diabetes and causing dyslipidemia. Our findings suggested that the levels of pre-diabetes uric acid levels should be under concern.

    ABSTRACT: Using the Back Propagation (BP) Neural Network Model to discover the relationship between meteorological factors and mortality of intracerebral hemorrhage, to provide evidence for developing an intracerebral hemorrhage prevention and control program, in Harbin. Based on the characteristics of BP neural network, a neural network Toolbox of MATLAB 7.0 software was used to build Meteorological data of 2007 - 2009 with intracerebral hemorrhage mortality to predict the effect of BP neural network model, and to compare with the traditional multivariate linear regression model. Datas from the multivariate linear regression indicated that the cerebral hemorrhage death mortality had a negative correlation with maximum temperatureand minimum humidity while having a positive correlation with the average relative humidity and the hours of sunshine. The linear correlation coefficient of intracerebral hemorrhage mortality was 0.7854, with mean absolute percentage (MAPE) as 0.21, mean square error (MSE) as 0.22, mean absolute error (MAE) as 0.19. The accuracy of forecasting was 81.31% with an average error rate as 0.19. The Fitting results of BP neural network model showed that non-linear correlation coefficient of intracerebral hemorrhage mortality was 0.7967, with MAPE as 0.19, MSE as 0.21, MAE as 0.18. The forecasting accuracy was 82.53% with the average error rate as 0.17. The BP neural network model showed a higher forecasting accuracy when compared to the multiple linear regression model on intracerebral hemorrhage mortality, using the data of 2010's.

    ABSTRACT: The association between the MTHFR C677T polymorphism and hyperuricemia has been investigated in several studies. Although these epidemiological studies have shown that genetic factors are determinants of serum uric acid levels, the power of the association is weak due to the small sample size. To study whether the MTHFR C677T polymorphism has an effect on hyperuricemia, we carried out a meta-analysis of case-control studies from PubMed, EMBASE and CNKI (China National Knowledge Infrastructure) databases mainly in English and Chinese. We used the odds ratio (OR) as main effect size; explored potential sources of heterogeneity; performed subgroup analyses by race and performed sensitivity analyses of studies meeting the Hardy-Weinberg equilibrium (HWE). Six studies with 1,470 subjects were included in the meta-analysis. Tests for heterogeneity showed the difference in OR among studies was not statistically significant (p = 0.63, I(2) = 0). When excluding the study of Caucasians not in HWE, the association remained robust (OR = 1.82, 95% CI 1.52-2.17) in the East Asian subgroup and sensitivity analyses. Although the mechanism of the relationship between the C677T polymorphism and uric acid still remains unclear, these original articles showed that the MTHFR C677T polymorphism may be an independent risk factor for hyperuricemia.

    ABSTRACT: To determine the prevalence and distribution of type 2 diabetes mellitus (T2DM) and the relationship between maximum body mass index (MAXBMI) and T2DM. From June to August, 2005, a stratified cluster sampling of 1071 permanent residents in communities, over 20 years old, from 4 districts and 1 county of Mudanjiang was chosen. The prevalence of T2DM, and the association between T2DM and different levels of the MAXBMI, current BMI were studied. The prevalence in the communities was 7.09% and in those with past maximum BMI >/= 28 kg/m(2), it was 12.10%. With the increase of past MAXBMI levels, the risk of T2DM patients also increased significantly (trend chi(2) = 17.387 23, P < 0.0001). Data from multifactor analysis showed that MAXBMI in the past was positively related to T2DM (OR = 3.06, P = 0.0013). In T2DM patients, the group with MAXBMI >/= 27.4 kg/m(2) had higher 2-hour postprandial blood glucose than those with lower MAXBMI (P = 0.0408). When compared with low maximum BMI group in normal blood glucose population, the group with higher MAXBMI (>/= 25.4 kg/m(2)) had higher blood glucose and greater change of BMI. In both groups that patients with T2DM and with normal glucose, in order to control blood glucose better, researchers should not only concern about the influence of the MAXBMI in the past, but also pay attention to constantly keep BMI at the normal range.

    ABSTRACT: To investigate metabolic syndrome components that influencing the prevalence of cardiovascular disease (CVD). Five hundred persons were selected from a unit in Nanning city, Guangxi, based on the cross-sectional study on a distribution of population with metabolic syndrome in 2004 and followed them up for 3.5 more years. Physical examination would include detection on blood pressure, glucose, serum cholesterol and body index etc. When someone suffered from cardiovascular disease would be viewed as an 'end-point event'. Criteria of diagnosis were under the basis of CVD from the WHO-MONICA. (1) The mean value of physical and biochemical index as BMI, waist circumstance, systolic pressure, diastolic pressure. Fast serum glucose, triglyceride in the population with more MS components were higher than the ones with less components. (2) The prevalence rates of CVD in the four groups were 2.97%, 4.19%, 7.97%, 11.88% respectively with significant differences between the groups (P = 0.0008). (3) Data from the logistic analysis manifested that when compared to the 0 group, the risk rate of CVD for groups having 1, 2, 3 components were 1.41, 2.68, 4.00 respectively. After adjusted age and sex, time of occurrences, results from the Cox model showed that the risk rate of CVD for groups with 1, 2, 3 components were 1.29, 2.47, 3.67 (RR 95%CI: 1.02 - 13.14) respectively. (4) Kaplan-Meier analysis showed that the cum hazard of CVD in the 3rd group was higher than in the 0, 1 group, and at the end of follow-up, the cum hazard of CVD was 12.7% in the 3rd group among population with metabolic syndrome. When increasing the number of components of metabolic syndrome, the higher risk ratio for population to suffer from CVD was seen. With the natural process of disease, the more components of metabolic syndrome in population, the higher cum hazard would influence the occurrence of CVD in the future.

    ABSTRACT: In recent years, there have been numerous papers emphasizing the relationship between Glutathione S-transferases polymorphisms and bladder cancer risk, but the findings have not reached a consensus. The relationship between glutathione S-transferase T 1 null genotype and bladder cancer susceptibility is now even more disputable. Therefore, we present a meta-analysis of (nested) case–controlled, genotype-based studies (including 37 studies, 6,986 cases and 9,166 controls) examining this association. Using a fixed-effect model, statistically significant increase was observed between glutathione S-transferase T 1 deletion and bladder cancer risk for the overall studies (OR = 1.12; 95% confidence interval (CI): 1.04–1.21; P = 0.004 for Z test; I 2 = 47.43 for heterogeneity). After adjusting the result using trim-and-fill method, the outcome still had significant difference with little downgrade (OR = 1.10, 95% CI = 1.02–1.18). Three potential sources of heterogeneity including ethnicity, source of control and smoking status were also assessed. Minor increased correlation was found only in population-based studies (OR = 1.16; 95% CI = 1.03–1.30; I 2 = 47.16). Our analysis suggests that glutathione S-transferase T 1 null status is associated with a modest increase in the risk of bladder cancer and the difference exiting in source of control has been confirmed. Due to limited sample size, various confounding variables as well as discrepancy in study design, a valid conclusion still cannot be confirmed.

    ABSTRACT: To provide the hard-won information on HIV-1 polymorphism from inmates in prison and to study the genetic variation of HIV-1 strains, we analyzed the characterization of the nucleotide and corresponding protein sequences of naturally occurring nef sequences derived from 16 HIV-1-positive inmates from prisons in China. Nested PCR and DNA sequencing were used to determine nef sequences in peripheral blood mononuclear cells. Phylogenetic analysis revealed a distribution of the viral sequences among subtype B, CRF_BC, and CRF_AE, with subtype B accounting for more than half of the genotypes. When compared with the consensus sequence, a certain amino acid sequence variability was observed. However, most of the described nef functional motifs were relatively well conserved in the majority of the sequences analyzed. Our results indicate that HIV-1 strains found in our study subjects may have a common origin and the description of motifs will produce important information for further studies of nef function.

    ABSTRACT: This study aimed to examine the factors related to the ability to obtain nipple aspirate fluids in Chinese women and to evaluate the diagnostic value of carcinoembryonic antigen (CEA) in nipple aspiration fluids. Cross-sectional and case-control studies were used to examine the factors associated with the ability to obtain nipple aspiration fluids. A matched case-control study was used to explore the association of CEA level in nipple aspiration fluids with breast disease. CEA level was log10-transformed to normalize the distribution. Univariate and multivariate logistic regression were adopted to analyze the variables in relation to obtaining fluid and the association of its CEA levels and breast diseases. Receiver operating characteristic curve was used to evaluate the value of CEA levels for the detection of breast disease. The nipple aspiration fluid collection rate was 34.24% (201 of 587). Multivariate logistic regression analysis results showed the following to be significantly associated with a greater ability to obtain nipple aspiration fluids: earlier age at menarche [odds ratio (OR), 2.61; 95% confidence interval (95% CI), 1.15-5.91], lactating>12 months (OR, 2.28; 95% CI, 1.44-3.60), wet-type ear wax (OR, 3.80; 95% CI, 2.39-6.02), and fatty diet (OR, 1.56; 95% CI, 1.02-2.39). CEA levels in nipple aspiration fluids of cancerous breasts were significantly higher than those from breasts with benign disease and healthy controls (ORadj, 5.39; P<0.01). However, the sensitivity of CEAs was 35.42% and the specificity was 85.42% whereas the CEA cutoff value was 307.61 ng/mL. The area under the receiver operating characteristic curve was 0.65. The nipple aspiration fluid collection rate in Chinese native women is lower compared to non-Asian-descendant women. CEA level does not seem to be a useful diagnostic tool for early cancer detection; it can only be used in conjugation with other methods.

    ABSTRACT: To explore the association between hypertension and the tendency of change among children,so as to lay a foundation for the prevention and control of hypertension. Based on findings from the prevalence survey that carried out in September 1999 in Daqing of Heilongjiang province. New admission children were selected as subjects to conduct a five-year cohort study. All the subjects were interviewed with questionnaires and their blood specimens were collected for biochemical analysis. All data were analyzed using SPSS 10.0 software. Results The prevalence of hypertension among 447 children was found 2.01% at the baseline study but increased to 5.37% in the fifth year. During a five year period, the systolic pressure level among children increased from (100.65 +/- 11.62)mmHg (1 mm Hg = 0.133 kPa) to (106.67 +/- 9.29) mm Hg,while the diastolic pressure level was from (66.27 +/- 11.31) mm Hg to (70.28 +/- 7.98) mm Hg and showed significant difference between boys and girls. There were association between hypertension and family history, body mass index (BMI), triglyceride, insulin, insulin resistance index while insulin sensitivity index and family history, BMI and insulin sensitivity index appeared to be the important factors. Children under this study were divided to 'with family history or without' and then every group was divided to 'with over weight-obesity or normal'. Obesity and insulin sensitivity seemed the key risk factors on hypertension. Descent of insulin sensitivity was an independent risk factor. The level of blood tension among children in Daqing city was higher than that from the national data. The present study confirmed that over-weight,obesity, heredity and insulin resistance were the risk factors of hypertension while insulin resistance was related to hypertension. The interaction of these risk factors was independent or correlated to each other.

    ABSTRACT: The lipoprotein-associated phospholipase A2 (Lp-PLA2) metabolizes oxidized phospholipids, generating lysophosphatidylcholine. The activity of the enzyme is known to be influenced largely by a single-nucleotide polymorphism, G994T, in the Lp-PLA2 gene. Interestingly, this polymorphism is much more prevalent in Japanese than Caucasians. The purpose of the current study was to evaluate the effects of the G994T, several environmental factors, and their interactions on the Lp-PLA2 activity in a large Japanese cohort. Participants (1,110 males and 908 females) of a health-screening examination were recruited for this study. Genotyping of the G994T was done using allele-specific polymerase chain reaction (PCR). The Lp-PLA2 activity was measured using commercial kits. The minor allele (994T) frequency of the polymorphism was 0.17 in this study, which was consistent with previous reports. According to the multivariate linear regression analysis, the G994T was the most potent factor influencing the enzyme activity (standardized beta=0.76), followed by the low-density lipoprotein cholesterol (LDL-C) level (standardized beta=0.32) and the sex (standardized beta=0.13). The LDL-C level showed a significant interaction with the G994T genotype. By contrast, no significant interaction was observed between the LDL-C level and the sex. These observations should provide useful information for future clinical and epidemiological evaluations of the Lp-PLA2 activity in cardiovascular diseases in Japanese.

    ABSTRACT: To explore the awareness on sever acute respiratory syndrome (SARS) and public health emergencies among general publics. A cluster sampling method was implemented in Harbin and Jiagedaqi district of Daxinanling of Heilongjiang province. Research subjects were divided into three groups as city, township and rural areas and were given questionnaires to fill in. Data was analyzed with Epi-data and SPSS. 2003 available questionnaires were collected. The general publics well understood the knowledge on public health emergencies and the SARS with the whole recognition rate more than 60 percent. During the epidemics, people in city, town and countryside were calm (71.7%). The rates of attitude towards the government were significantly different among the subjects living with the city, town or rural areas. The city group expressed the highest favor to the government and media, 71.8% of them gave the credit on the control of SARS to the effective method taken by the government and 65.0% of them showed that they had enough confidence on the governmental ability of dealing with crises while the countryside group trusted the hospitals and relative specialists the most. It is essential for the government to interact and communicate with the publics through media, medical and related institutions when confronting with the public health emergencies. Publicity on health knowledge and coping system on emergency should play key roles in the development of an effective public health system while the government should lead the battle.

    ABSTRACT: To examine the effect of pseudolaric acid B on the growth of human gastric cancer cell line, AGS, and its possible mechanism of action. Growth inhibition by pseudolaric acid B was analyzed using MTT assay. Apoptotic cells were detected using Hoechst 33258 staining, and confirmed by DNA fragmentation analysis. Western blot was used to detect the expression of apoptosis-regulated gene Bcl-2, caspase 3, and cleavage of poly (ADP-ribose) polymerase-1 (PARP-1). Pseudolaric acid B inhibited the growth of AGS cells in a time- and dose-dependent manner by arresting the cells at G(2)/M phase, which was accompanied with a decrease in the levels of cdc2. AGS cells treated with pseudolaric acid B showed typical characteristics of apoptosis including chromatin condensation and DNA fragmentation. Moreover, treatment of AGS cells with pseudolaric acid B was also associated with decreased levels of the anti-apoptotic protein Bcl-2, activation of caspase-3, and proteolytic cleavage of PARP-1. Pseudolaric acid B can dramatically suppress the AGS cell growth by inducing apoptosis after G(2)/M phase arrest. These findings are consistent with the possibility that G(2)/M phase arrest is mediated by the down-regulation of cdc2 levels. The data also suggest that pseudolaric acid B can trigger apoptosis by decreasing Bcl-2 levels and activating caspase-3 protease.
