International Journal of Cerebrovascular Diseases 2014;22(10):751-755
Objective To investigate the correlation between the NADPH oxidase p22phox-A930G polymorphism and hypertensive intracerebral hemorrhage in Chinese Han population in Shanghai area.Methods The patients with hypertensive intracerebral hemorrhage and normal controls were enrolled.The polymerase chain reaction and the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) were used to detect the genotypes and alleles of NADPH oxidase p22phox-A930G.Results A total of 128 patients with hypertensive intracerebral hemorrhage and 151 healthy controls were enrolled.The levels of systolic blood pressure,diastolic blood pressure,glucose,and triacylglycerol,as well as the proportions of smoking and alcohol consumption in patients of the hypertensive intracerebral hemorrhage group were significantly higher than those of the control group (all P< 0.05).There were significant differences in AA,AG,and GG genotypes (42.2%,44.5%,and 13.3% vs.63.6%,27.8%,and 8.6%,x2 =12.757,P =0.002) and in A and G allele (64.5% and 35.5% vs.77.5% and 22.5% ;x2 =8.734,P=0.001) frequencies between the hypertensive intracerebral hemorrhage group and the control group.Multivariatelogistic regression analysis showed that systolic blood pressure ≥ 140 mm Hg (1 mm Hg =0.133 kPa) (odds ratio [OR] 13.952,95% confidence interval [CI] 7.242-26.879; P < 0.001),apolipoprotein A ≥ 0.99 mmol/L (OR 3.139,95% CI 1.012-9.733; P =0.048),and AG +GG genotype (OR 2.333,95% CI 1.253-4.342; P=0.008) were the independent risk factors for hypertensive intracerebral hemorrhage.Conclusions Among the Chinese Han population in Shanghai area,the NADPH oxidase p22phox-A930G polymorphism is an independent risk factor for hypertensive intracerebral hemorrhage.

3.Expression and role of SPARCL1 gene in tumor
Journal of International Oncology 2016;43(9):673-675
Abnormal expression of secreted protein acidic and rich in cysteine like 1 (SPARCL1 )gene is closely related to the development,metastasis and prognosis of a variety of tumors.Recent studies show that SPARCL1 gene is high expressed in glioma.The protein product of SPARCL1 gene encoded can interact with collagen,thus affecting the metastasis ability of tumor,which is positively correlated with tumor malignant de-gree.SPARCL1 gene is low expressed in gastric cancer,colorectal cancer,prostate cancer and breast cancer, which is negatively correlated with the invasion and metastasis abilities of tumors.At present,the role of speci-fic molecular mechanisms of SPARCL1 gene remains controversial. The expressions and functions of SPARCL1 gene in tumor tissues seem to depend on the tumor microenvironment.

Journal of Environment and Health 1993;0(03):-
Potential toxicities of three classes of dyes and pigments were introduced in this review. Some azo/benzidine dyes, anthraquinone dyes and triarylmethane dyes have carcinogenicity,some azo/benzidine dyes and anthraquinone dyes may cause skin irritation, some noncarcinogenic triarylmethane dyes have risk of serious damage to eyes and may exert long term adverse effects on the aquatic environment.
6.THE GLASS CAPILLARY GAS CHROMATOGRAPHIC METHOD FOR THE ANALYSIS OF FATTY ACIDS
Acta Nutrimenta Sinica 1956;0(01):-
A gas chromatographic method was established for the analysis of fatty acid composition of oils. After methlation of the samples, the retention time of the fatty acid esters in the glass capillary coated with crosslin-ked methyl silicone was closely related to the number of carbon atoms.The reproducibity of this method was satisfactory. The relative standard deviation was 0.4-1.5%. Six kinds of vegetable oils were analyzed by this method, and the results were consistent with those reported by Canadian Cereal Association. For analysis of the free fatty acid composition of becte-ria, the results were comparable with those obtained from thin layer chroma-tography and chemical analysis.

Chinese Journal of Hospital Administration 2012;28(6):422-426
Objective To analyze the variations and influencing factors of hospitalization expenditure of cervical cancer patients among urban employees in Beijing from 2006 to 2010,and to provide evidences for developing reasonable measures of medical expenses control.Methods Based on the hospitalization expenditure data of 1146 cervical cancer cases,the paper probed into the changes of hospitalization age and hospitalization expenditure,and the influencing factors of hospitalization expenditure by means of descriptive analysis and multiple stepwise regression.Results The last 5 years witnessed no significant change in the first hospitalization age of cervical cancer patients,rise of hospitalization age,gradual rise of the hospitalization expenditure per time along with their age groups,as well as a rising trend of the average hospitalization expenses,average drug cost and proportion of average drug cost year by year.Results of the multiple stepwise linear regression showed that days of stay,proportion of drug cost and surgery or not as important influencing factors for hospitalization expenditure.Conclusion Hospitalization expenditure of cervical cancer keeps growing.Against this background,reasonable shortening of the days of stay,reasonable setup of an appropriate proportion of out-of-pocket payment,and reduction of the proportion of drug costs become effective means to reduce hospitalization expenditure.
