Objective： The current study was designed to investigate the polymorphisms of DNA repair gene XRCC1 in Chinese population and test the hypothesis which these genetic variations may have impact on the risk of esophageal squamous cell carcinoma(ESCC). Methods： A case control study of 222 ESCC patients and 433 control subjects (matched for age, sex) was conducted to investigate the role of two XRCC1 polymorphisms(XRCC1 26304 T and XRCC1 281152 A) in ESCC. Genotyping was performed using PCR based restriction fragment length polymorphism techniques. The adjusted odds ratio (OR) and 95％ confidence interval (CI) was calculated using multivariate logistic regression. Results： Genotype frequencies of the XRCC1 C26304T were 51.7％ (CC), 41.6％ (CT) and 6.7％ (TT) in control group. The frequency of TT allele in control group (6.7％ ) was significantly lower than that in case group (12.6％ ), with the adjusted OR for ESCC being 1.83 (95％ CI 1.03－ 3.24; P< 0.05). Furthermore, the risk of ESCC for XRCC1 26304 TT alleles appeared to be more pronounced among smokers (adjusted OR=3.1,95％ CI 1.3－ 7.2) compared to nonsmokers (adjusted OR=2.3, 95％ CI 1.0－ 5.4), and among smokers who smoked≥ 20 cigarettes/day (adjusted OR=6.4, 95％ CI 2.0－ 23.7) compared to those who smoked< 20 cigarettes/day (adjusted OR=1.0, 95％ CI 0.2－ 4.3). Genotype frequencies of the XRCC1 G28152A were 53.3％ (GG), 38.1％ (GA) and 8.6％ (AA) in control group, which were not significantly different from that in case group. Conclusion： These findings support the hypothesis which polymorphism in XRCC1 DNA repair gene contributes to the risk of developing ESCC.

Objective To evaluate the effect of application of clinical nursing pathway to treatment of acute ST--Elevation myocardial infarction (STEMI).Methods A total of 60 STEMI patients were divided into two groups.Experimental group were received treatment and care according to the designed STEMI clinical pathway table.Control group were treated and nursed with the conventional emergency mode.Results The time of emergency PCI of the experimental group was less than teat of control group(P<0.05)treatment success rate was higher than the control group.Total hospital costs,medicine costs and hospital days were significantly lower in experiment group,while health education and satisfaction were significantly higher(P <0.05).Conclusions The application of clinical pathway in the STEMI could win precious time of their treatment for patients,reduce medical costs and improve quality of care.It is in line with the current demand of China's health system and therefore is worth to promoting.

IgG4-related disease (IgG4-RD) is a newly recognized fibro-inflammatory condition of autoimmune etiology in recent twenty years, mainly manifesting as mass-forming lesions in single or multiple organs. In the past, it was often missed or misdiagnosed as inflammation or tumor. Patients may die from multiple organ failure due to end-stage fibrosis if they are not treated promptly. However, the number of clinically confirmed cases has gradually increased with the improvement of diagnostic level in recent years, and these patients have benefited greatly after receiving early treatment. Although patients generally respond well to traditional immunosuppressors including glucocorticoids and disease-modifying anti-rheumatic drugs, refractory and recurrent cases, even patients with glucocorticoid contraindication are common. Important mechanistic insights have been derived from studies of B-cell depletion therapy, but greater awareness of the pathophysiology of IgG4-RD is still badly needed to identify novel therapeutic targets. In this article, we reviewed the pathogenesis progress and promising therapy of IgG4-RD to seek better clinical management of IgG4-RD.

Objective To explore coping style and the economic burden of disease in the patients of cerebral ischemic stroke and to find new psychological nursing measures. Methods Questionnaire and homemade scale was used, 233 cases with cerebral ischemic stroke in Xuzhou Medical School Affiliated Hospital neurology department were collected and were divided into four groups( social insurance group, own expense group, residence health insurance group, and new cooperative medical service insurance group). Data were classified and analyzed by SPSS 16.0 software. Results Face factors, avoid factors, yield factors and total score in the coping style were significantly different in the four groups ( F = 32. 11,9. 23,22. 12,5. 82 ; P <0. 01 ), and personal expense, related examine expense and day in hospital in the economic burden of disease were significantly different in the four groups ( F = 41.85,4. 27,4. 72 ; P < 0. 01 ). However, total expense in hospital and average expense were not different ( F = 2. 10,1.62; P > 0. 05 ). Conclusions Social insurance system as a society' s important support affects coping style in the patients of cerebral ischemic stroke.

OBJECTIVETo compare the serological characters of an outbreak of hepatitis E and evaluate sensitivity and specificity of anti-HEV E2-IgM.

METHODSThe sera collected from the employees of an outbreak unit were detected for anti-HEV E2-IgM and IgG, and the serum samples from a neighboring department were used as control. The results detected with anti-HEV E2-IgM, IgG and Genelab anti-HEV IgM, IgG in some samples were compared.

RESULTSThe positive rate of anti-HEV E2-IgM in the control group was 0.11%. The results between the positive and the negative samples can be distinguished easily. The specificity of anti-HEV E2-IgM is about 99.89%. The positive rate of anti-HEV E2-IgM in outbreak stricken population was 8.66%, significantly higher than that in the control group (P < 0.001). The results from HEV patients' serial samples in the outbreak unit showed that the anti-HEV E2-IgM titer was high 30-60 days after the infected and then declined clearly. The positivity seemed unrelated to neither sex nor age. Among the 115 positive to anti-HEV E2-IgM, 27 were negative to Genelab anti-HEV IgG, the fact indicated a rather high risk of misdiagnosis of about 23.48%. In the 179 randomized samples of the control group, the positive rate of Genelabs anti-HEV IgG was about 11.17%. In 110 samples for the positive anti-HEV E2-IgM, the positive ratio of Genelabs anti-HEV IgG was about 76.36%, and that of Genelabs anti-HEV IgM only 69.09%. There were 16 samples negative for both Genelabs anti-HEV IgG and IgM. The ratio of the difference between the Genelabs anti-HEV IgG and IgM was about 25.45%.

CONCLUSIONThe specificity of anti-HEV E2-IgM was about 99%, and false positive rate was low. The sensitivity of anti-HEV E2-IgM in acute hepatitis E infection was 25%-30% higher than that of Genelabs anti-HEV IgM,IgG. The infected persons in the outbreak unit can be preferably distinguished from the non-infected persons by anti-HEV E2-IgM. Anti-HEV E2-IgM can image the characters of the outbreak of HEV and played a great role in the control of outbreak and in the early diagnosis for hepatitis E.

OBJECTIVETo investigate the expression of SOX2 in cervical intraepithelial neoplasia (CIN) and cervical cancer and explore its association with the clinical features.

METHODSSOX2 expressions were examined using immunohistochemical method in 10 normal cervical tissue specimens, 36 cervical intraepithelial neoplasia specimens (including 10 cases of grade I, 12 of grade II, and 14 grade III) and 40 cervical cancer specimens (including 21 cases of stage I and 19 of stage II). The correlation between the immunohistochemical results and the clinical features of the patients was analyzed.

RESULTSSOX2 expression was negative in normal cervical tissues, and was positive in 41.6% of CIN specimens (10.0% in CIN I, 41.7% in CIN II, and 64.3% in CIN III) in 82.5% of cervical cancer specimens (78.2% in stage I and 88.2% in stage II). The patients with cervical cancer had a significantly higher positivity rate of SOX2 than normal control group (P<0.05). The positivity rate of SOX2 increased with the evolution of cervical disease. SOX2 protein expression was significantly correlated with the histological grade and lymph node metastasis (P<0.05), but not with the age or clinical stage of the patients (P<0.05).

CONCLUSIONSOX2 expression may serve as a useful indicator for evaluating metastasis and malignancy of cervical cancer.

OBJECTIVETo study the effect of multiglycosides of Tripterygium wilfordii (GTW) on sperm apoptosis in male rats and its possible mechanisms.

METHODSSixteen male SD rats were equally assigned to two groups to receive GTW and carboxymethylcellulose (CMC) intragastrically, both at 20 mg/(kg x d) for 6 weeks. Then the epididymal sperm was collected for the measurement of the apoptosis rate, sperm membrane lipid fluidity and the contents of NO, MDA and SOD by flow cytometry and spectrophotometric determination.

RESULTSAfter 6 weeks of medication, the GTW group showed a significant increase in sperm apoptosis and contents of NO and MDA (P < 0.01) and a remarkable decrease in sperm membrane lipid fluidity (P < 0.05) and SOD content (P < 0.01) as compared with the CMC control group.

CONCLUSIONGTW can damage sperm membrane lipid peroxidation and sperm membrane structure, increase sperm apoptosis, and reduce sperm membrane lipid fluidity.
