Objective To investigate the impact of methylene tetrahydrofolate reductase (MTHFR) gene polymorphism on folicacid for lowering plasma level of homocysteine in elderly patients with coronary heart disease (CHD). Methods In the first affiliated hospital of Zhengzhou university,a total of 180 elderly patients with CHD were randomized to two groups. The study group (91 ptients) received folicacid 5mg once daily and the control group (89 patients) received no folic acid. 8 weeks after treatment, the changes in plasma Hcy were observed and analyzed by MTHFR genotypes (TT vs. CC vs. CT). Results Plasma Hcy of the three genotypes had a statistical significance at the baseline (P<0.001), among which plasma Hcy level was the hightest in patients with genotype TT, while it had on difference in genotypes CC and CT (P = 0.057). 8 weeks after treatment, plasma Hcy level declined up to 24%in the patients with genotype TT in the study group, while it decreased about 6%and 15%in patients with genotype CC or CT, separately. Hcy level was slightly decreased in the patients with genotype CC, CT, or TT in the control group. Conclusions Plasma Hcy level differs statistically in three genotypes, and it is the highest in genotyp TT. Folicacid can effectively lower the level of plasma Hcy in elderly patients with CHD, especially those with genotype TT.

It is a well-recognized difficult empirical task to disentangle the moral hazard effect from adverse selection impact by using the health insurance data in the empirical research of health economics. In the research, the unique social experiment in China’s health care reform, which enables cleanly identify moral hazard is applied. Using individual-level hospital patient data, it estimates the impact of the reimbursement rate increase on Chinese patients’ demand for health care service. Difference-in-Difference Propensity Score Matching approach and find strong evidence for moral hazard are approached. For instance: if the reimbursement rate increases by 5% while other factors remain the same, the corresponding health care service expenditure will increase by around 7%. The finding also has important implication for policy making. Chinese government pledges to lower the average individual out-of-pocket cost from the current 37.5% of total health care service cost to 30 % in 5 years. According to the former estimation, if the goal of the policy is successfully achieved, moral hazard problem itself will cost Chinese health care system around 200 billion yuan.

It is always an important academic and policy issue to understand the impact of hospital distance on Chinese inpatient service demand in rural areas. It employs household survey data collected from 97 villages in Shandong in 2006 and 2008, and investigates the influences of hospital distance on the demand of famars in rural areas. The discrete choice model is constructed to estimate the inpatient service demand function for patients in rural areas. The empirical analysis finds that the hospital distance is significantly affecting Chinese inpatient service demand in the rural areas. The longer the distance increases, the lower the visiting rate drops. In addition, the impact changes with the changes of hospital level; the lower the primary hospital is, the higher the impact would be. It paper provides new evidence for the understanding of the geographical characteristics of medical health care.

With GC-MS、LC-UV and gene analysis,we studied Pseudonomas sp.W2 metabolic pathway of bisphenol A(Bpa).It was discovered that 4'-(trimethylsiloxy)-Acetophenone、p-Hydroxy benzaldehyde and p-Hydroxy benzoic acid are medium metabolites and that the bacteria has pcaG.

Objective To study the relationship between Poly(ADP-ribose) glycohydrolase(PARG) and Poly(ADP-ribose) polymerase(PARP) in colorectal carcinoma.MethodsImmunohistochemical S-P staining was used to examine the expressions of PARG and PARP in 44 specimens human colorectal carcinoma.The positive rate of PARG and PARP in murine colon carcinoma CT26 cells was detected by flow cytometry before and after the treatment of PARG inhibitor Gallotannin.ResultsPARG and PARP expressed in colorectal carcinoma specimens was of positive correlation(r=0.300 01,P

Objective To investigate the relationship between the polymorphism of the tumor necrosis factor-αgene-308 promoter and bronchial asthma (BA)in Uighur and Kazakh population in Xinjiang.Methods PCR product sequencing method was used to detect the polymorphism distribution of TNF-αgene in 60 BA patients and 60 controls among Xinjiang Uighur and Kazakh population.Then we analyzed the association between different TNF-αgenotypes and BA in Uighur and Kazakh population.Results The distribution of GG,GA and AA genotype was significantly different between the two groups.Statistical analysis showed that BA group had a significantly higher TNF-αA allele frequency than that of the control one (P <0.05).After adjustment for sex and age,we found the A allele was a risk factor for BA pathogenesis (P <0.05).Conclusion The polymorphism of TNF-α gene-308 may be associated with the susceptibility to BA in Xinjiang Uighur and Kazakh population,so TNF-α gene-308 may be considered as a genetic marker for early identification of individuals at high risk for BA,which may play an important role in preventing the development of BA in clinical practice.

Objective　To investigate the epidemiological characteristics of pulmonary tuberculosis among students in Fuzhou City in 2022 and the screening of their close contacts, so as to provide scientific basis for further prevention and control of tuberculosis in schools. Methods　A descriptive method was used to investigate the campus tuberculosis epidemic situation in 87 colleges and universities in Fuzhou, and 96 cases of confirmed student patients were investigated individually, and 7 488 close contacts were screened according to the requirements of the Guidelines for tuberculosis Prevention and Control in Chinese Schools, and the results were analyzed. Results　In 2022, a total of 96 students with pulmonary tuberculosis were found in Fuzhou City, with a male to female ratio of 1.04∶1 and an average age of 17.92 ± 4.16 years. The incidence rate of active pulmonary tuberculosis and the incidence rate of bacterial positive pulmonary tuberculosis among university and college students were higher than those among other types of schools, separately 10.56/100 000 and 5.18/100 000, with significant differences (χ2=75.22, P<0.05; χ2=38.69, P<0.05). The proportion of student patients was the highest in the first quarter (34.38%, 33/96). There were 44 cases of delayed visits, with a delay rate of 45.83% (44/96). The diagnosis was delayed in 15 cases, with a delay rate of 15.63% (15/96). Screening of 7 488 close contacts, of which 5 339 were screened with chest radiography and 5 active cases were found. A total of 7 124 patients were screened by the tuberculin skin test (TST test), the positive rates of TST test results for close contacts of pathogenic and no pathogenic patients were 25.97% (1 135/4 371) and 21.10% (581/2 753), respectively. The strong positive rates were 6.15% (269/4 371) and 3.01% (83/2 753), respectively, with statistically significant differences (χ2=21.84, P<0.05; χ2=35.44, P<0.05). Conclusion　In 2022, the incidence of tuberculosis in schools in Fuzhou City was dominated by students from universities and colleges, with the highest incidence rate in the first quarter. The delay in seeing a doctor and diagnosis of student patients was serious. Timely and effective screening of close contacts (especially the close contacts of patients with bacterial positive pulmonary tuberculosis) can reduce the spread of tuberculosis in schools.

According to the characteristics of the etiology and pathogenesis of child cerebral palsy, on the basis of "regulating the mind in treatment of all kinds of diseases" and "regulating the functions of five zang organs with back-shu points", Professor DONG Gui-rong applied the penetrating needling technique on the scalp points and acupuncture at back-shu points of five zang organs in the treatment of child cerebral palsy. The valuable clinical experiences have been summarized as "regulating the mind with scalp needling technique, benefiting the brain and opening the orifice", "regulating five zang organs with back-shu points" and "integration of acupuncture and rehabilitation, and function reconstruction". Two effective cases were introduced.
