ABSTRACT
Objective To assess the current status and factors associated with the mental health condition of older adults. Methods A convenience sampling survey was conducted using symptom check list 90 (SCL-90) among the Chinese older adults aged 60 or above from January to March, 2018. The older adults aged 80 or above were selected for this study. Chi-square test and binary logistic regression model were used to analyze the influencing factors. Results The total participants were 485. The SCL-90 positive detection rate was 20.21%. The symptoms of the four highest detection rates were somatization (39.38%), others (25.15%), obsessive-compulsive symptoms (24.33%) and depression (22.68%). The older adults with normal BMI (OR=0.537, 95% CI: 0.250-0.857, P=0.027) and lived in county town (OR=0.224, 95% CI:0.075-0.667, P=0.007) showed lower SCL-90 positive detection rate. These who had been educated for 1-5 years (OR=11.092, 95% CI: 4.446-27.671, P<0.001), 6-8 years (OR=9.800, 95% CI: 3.464-27.721, P<0.001), 9~11 years (OR=19.279, 95% CI : 6.722-55.297, P<0.001), 12 years and above (OR=24.321, 95% CI: 7.894-74.929, P<0.001) had higher SCL-90 positive detection rate compared with those who were uneducated. Conclusion The mental health condition of Chinese older adults is mainly influenced by residence place, education level, family income self-evaluation and BMI status.
ABSTRACT
Objective To establish a predictive model for inpatients of cardio-cerebrovascular disease in rural areas of Wugang through time series analysis, and predict the changing trend of cardio-cerebrovascular disease, so as to offer guidance for the health care resources allocation and prevention and control of cardio-cerebrovascular disease. Methods The seasonal autoregressive integrated moving average model (SARIMA) was constructed based on the monthly number of cases of cardio-cerebrovascular disease in rural areas from January 2013 to December 2016 by Stata 14.0 software, and the predictive effect of the model was verified with the monthly number of inpatients of cardio-cerebrovascular disease in 2017. Results The final fitting model of inpatients of cardio-cerebrovascular disease was SARIMA (2, 1, 1)×(0, 1, 0)12. The residual sequence of the model was diagnosed. Results of Ljung-Box Q test showed that the residual sequence was white noise sequence (Q=11.12, P=0.68). In addition, the 2017 forecast was basically consistent with the observations, the overall relative error was around -1.2%. The results showed that the summer was the peak period of cardiovascular and cerebrovascular hospitalization. Conclusion SARIMA model can accurately predict the number of inpatients of cardio-cerebrovascular disease in Wugang, which can provide data support for the hospital administrator to rationally allocate medical resources in the cardiovascular according to the needs of cardio-cerebrovascular treatment in different months.
ABSTRACT
Objective:To summarize and analyze the status of health cooperation achievement strategies between China and the countries along the "Belt and Road",determine the implications thereof, and provide reference for future practical cooperation between the China and those countries in the field of health. Methods : The relevant literature was retrieved from the research database from articles published in both Chinese and English during the period from 2013 to 2017, and the literature research method was used to summarize the status quo of health cooperation. Results : According to the exclusion criteria, 116 articles were selected. The analysis showed that the main research focus falls in the following seven aspects for both domestic and foreign scholars : The dissemination of Chinese medicine culture promotes international cooperation in Chinese medicine; the prevention and control of infectious diseases needs to further strengthen the construction of international mechanisms; the health services and systems requiremutual learning from international experience; health industry has broad prospects for development; health emergency cooperation encounters the problem of inadequate coordination mechanisms and language barriers; the research on health development assistance goes deep; and health professionals training focuses on training mode. Conclusions: The existing research topics were of great coverage in range and had the highest attention to Chinese medicine,yet least considered talent cultivation. The research showed that cooperation in various health departments emphasized on international experience and the joint participation of the government and civil society. However, the research on laws and regulations, international conventions and practices, and different families' cooperation requirements related with health cooperation mechanisms need to be further strengthened.
ABSTRACT
Objective: To understand the health cooperation intentions, demands, advantages and obstacles that are being experienced by countries along the Belt and Road,and to provide reference for China to deepen health cooperation with those countries in regard. Methods : A seminar was held at the High Level Symposium to find out about the health cooperation status among the "Belt and Road" countries, whereby the theme was: "Belt and Road for Health Cooperation towards a Health Silk Road". Therefore, a survey was conducted among 217 Chinese and foreign guests who were invited to attend the seminar. 209 questionnaires were valid and the effective rate was 96. 3％ after the questionnaire analysis carried out using SPSS22. 0. Results : Research results showed that among the respondents, 91. 7％ of the surveyed foreign partners are willing to cooperate in health, while only 73. 2％ of the Chinese respondents desired the cooperation. The demands for health cooperation between both countries was mainly about health industry,medical and health services, and infectious disease prevention and control. Both China and foreign countries confirmed that cooperation convenience and long-term partnership were the advantages of health cooperation among Belt and Road countries, while differences were highlighted in preferential policies. The biggest challenge was found to be the cultural differences. Among other disadvantages are the lack of communication platforms, the pressure of laws and regulations, unstable policies, etc. Conclusions : The willingness and broad space to cooperate in health are strong and large forboth China and foreign countries,and they are intending to put much of emphasis on health institutions,medical and health services and prevention and control of infectious diseases in the future. It is hence suggested that health cooperation should make good use of existing advantages of partnership and convenience,and overcome found obstacles in orderto deepen cooperation in the health industry.
ABSTRACT
<p><b>BACKGROUND</b>Endogenous estrogen plays a very important role in the carcinogenesis and progression of breast cancer. The enzymes involved in the biosynthesis and metabolism of estrogen have been proposed to contribute to this effect. To examine this hypothesis, we conducted a case-control study to investigate the relationship between polymorphisms of genes responsible for estrogen biosynthesis (CYP17, cytochrome P450c17a and CYP19, aromatase cytochrome P450) and estrogen sulfation of inactivation (SULT1A1, sulfotransferase1A1) and the risk of breast cancer in Chinese women.</p><p><b>METHODS</b>This study involved 213 breast cancer patients and 430 matched controls. PCR-based restriction fragment length polymorphism (RFLP) and short tandem repeat polymorphism (STRP) assays were used to detect the mononucleotide transition of CYP17 and SULT1A1 and tandem repeat polymorphism of CYP19. Logistic regression analyses were used to determine OR and 95% CI of each and all three high-risk genotypes, of all three genotypes combined, and of estrogen exposure factors. The relationship between each high-risk genotype and clinicalpathological characteristics were also assessed.</p><p><b>RESULTS</b>The frequency of A2 allele of CYP17 was 49.8% in cases and 49.1% in controls (P = 0.82). The frequency of His allele of SULT1A1 was significantly higher in cases (13.6%) than in controls (9.5%) (P < 0.05). There was also significant difference of the (TTTA) 10 allele of CYP19 which was 12.4% in cases and 8.2% in controls (P < 0.05). When the CYP17 A2 allele, CYP19 (TTTA) 10 and SULT1A1 His allele were considered as the "putative high-risk" genotype, there was an increased risk of breast cancer with the number of high-risk genotypes in a dose-response effect (trend, P = 0.05). In multivariate analysis, the SULT1A1 genotype remained the most significant determinant for breast cancer, with OR = 2.37 (95% CI 1.23-4.74), followed by CYP19, with OR = 1.75 (95% CI 1.27-3.56). The (TTTA) 10 allele of CYP19 was associated with tumor size, and the His allele of SULT1A1 associated with status of lymph node metastasis.</p><p><b>CONCLUSIONS</b>This study supports the hypothesis that breast cancer can be initiated by estrogen exposure and that estrogen metabolizing genes are involved in this mechanism. This multigenic model is useful for identifying individuals who are at higher risks of breast cancer.</p>

<p><b>OBJECTIVE</b>To investigate the differential expression of apoptosis genes in patients with different degrees of benzene poisoning by cDNA microarray.</p><p><b>METHODS</b>Peripheral mononuclear cells were isolated from seven patients with benzene poisoning of different degrees (suspected 1 case, moderate 2, severe 2), and seven age and sex matched normal control subjects. Total RNA was extracted and purified, followed by reverse transcription to cDNAs with concomitant incorporation of fluorescent dCTP (Cy3 or Cy5). Then 177 genes associated with cell apoptosis were hybridized against the cDNAs probes in microarray. Fluorescent signals were scanned to detect apoptosis genes differentially expressed in patients and normal subjects.</p><p><b>RESULTS</b>Forty one genes were found to be differentially expressed between benzene-poisoned patients and normal controls; among the 41 genes, three were up-regulated among patients with mild to moderate degrees of benzene poisoning and one up-regulated among all patients. The total amount of differentially expressed genes of apoptosis decreased with the aggravation of benzene poisoning.</p><p><b>CONCLUSIONS</b>Differential expression of apoptosis genes was found in patients with benzene poisoning, suggesting a role of altered apoptosis in benzene-induced hematotoxicity.</p>
