Objective To establish the rational antibiotic treatment by accurate screening of high level aminoglycoside (HLA) resistant enterococci in clinical laboratory. Methods A single HLA genta micin 500 ?g/ml and streptomycin 200 ?g/ml for agar dilution method, and gentamicin 120 ?g/disk and streptomycin 300 ?g/disk for disk diffusion method were used as parallel screening tests to detect high level aminoglycoside resistance in 172 enterococci strains. Antibiotic time kill test was performed to verify the accuracy and reliability of both methods.Results The resistant rates of the two methods for HLA gentamicin were 60.0% and 59.3%,respectively. While for HLA streptomycin, both were 61.1%. In disk diffusion tests of 172 enterococci strains, the resistant rates for penicillin, ampicillin and vancomycin were 16.9%, 14.0%, and 1.7%, respectively. ? lactamase from 80 strains enterococci were all negative. Conclusion High concentration aminoglycoside disk diffusion method is a simple, reliable method for screening the HLA resistant enterococci in clinical laboratory. The results can provide a rational base for physicians to treat enterococcal infections.

Objective To investigate the elinicopathologic features of atypical endometriosis(AEM) and to discuss the relationship between AEM and tumors. Methods A retrospective analysis was performed of 163 cases of AEM, which were retrieved from the Department of Pathology files at the Tianjin Central Obstetrics and Gynecology Hospital between Jan 2004 and Dec 2006. The pathologic changes of AEM including its glandular epithelium, stroma, background and the conditions coexisting with tumor were observed. Results The AEM accounted for 4.38% (163/3724) of the endometriosis (EM) eases. Of 172 AEM foei of 163 patients, 168 were in the ovary, and the other 4 were in the fallopian tube, cervix and uterine serosa respectively. The rate of ovarian AEM was 6.81% of endometriosis. AEM associated with tumour was found in 26 cases (15.95% )and among 27 of ovarian AEM, 15 were malignant, 9 borderline and 3 benign. The AEM epithelia were mainly arranged in the form of surface epithelium. They present with characteristic features of moderate to marked pleomorphism, epithelial tufting and bud structures by microscopy. The walls of AEM cyst were presented with three layers of epithelium, endometrioid stroma and fibrosis-collngen. The endometrioid stroma were usually thin in contrast to the fibre-collagen tissue, which was often thick with scarred background. The transformation from AEM to tumor was found in most of the malignant tumors( 14/15,93% ). Conclusions AEM lesions hold some features of both EM and tumor, which may have a relatively higher potential for tumorigenesis and cancerafion. The process of damage and repair in EM foci during a long course may play a role in the development of EM into AEM and finally into tumor.

This study was aimed to collect relevant provisions of bulging disease medical records in the Ming and Qing dynasties to excavate the syndrome differentiation, drug law and medication frequency analysis. A database was established to analyze relevant provisions. The results showed that the syndromes of liver stagnation and spleen deficiency, dampness-heat accumulation, spleen-yang deficiency are the most common type. The mainly used drugs are from the category to eliminate dampness and water, and to tonify the deficiency. The top three used drugs are poria, atractylodes, and dried citrus peel. It was concluded that medications used in the Ming and Qing dynasties were mainly targeted to the disordered zangfu-organ, which was mainly about the spleen and the stomach. The syn-drome differentiation is the mixture of deficiency and excess. And deficiency is the main part. The medication should combine tonification and reducing. And tonification should be paid attention to. The syndrome differentiation and treatment should be coordinated and the primary and secondary aspect should be identified. These rules provide ref-erence effect for the clinical practice and scientific research of bulging disease treatment.

Objective:Based on the detection of CD4+IL17+Th17 and CD4+CD25+Foxp3+Treg cells in the peripheral blood of patients with human papilloma virus (HPV), the study analyzes the ratio of Th17 to Treg and compares the different expression of cytokine IL-17, IL-10, TGF-β, and IL-23 in the serum. Methods:From September 2014 to June 2016, 119 cases of untreated patients with cervical HPV in-fection were collected at the First Affiliated Hospital of Xinjiang Medical University, which include 46 cases of cervical cancer (CC), 43 cases with cervical intraepithelial neoplasia (CIN)Ⅱ-Ⅲ, and 30 with chronic cervicitis (CCS). The detection of HPV types classified 80 patients as high-risk and 39 as low-risk. Flow cytometry examined Treg and Th17 cells, and enzyme-linked immune sorbent assay was used to test related cytokines. Results:In the infection of high-risk cervical HPV, the rate of the CC group was 87%(40/46), which was higher than that of the CINⅡ-Ⅲgroup and the CCS group, which were 77%(33/43) and 23%(7/30), respectively. For the expression of Th17 and Treg cells in the peripheral blood and the related cytokine IL-17, IL-23, TGF-β, and IL-10 in the serum, the levels of CC group were also significantly higher than that of the other two groups, and the ratio of Th17 to Treg increased considerably with the se-verity of cervical lesions. The expression of Th17 and Treg cells in the peripheral blood of patients with high-risk cervical HPV were higher than that of patients with low-risk cervical HPV (P<0.05), which was the same for the expression of the related cytokine IL-17, IL-23, TGF-β, and IL-10 in the serum. The ratio of the Th17 to Treg of patients with high-risk cervical HPV increased remarkably (P<0.05). Conclusion:The expression of Treg and Th17 cells in high-risk patients exhibits an increasing trend, and the ratio of increased Th17 to Treg may directly participate in the process of HPV infection and immune evasion, which plays an important role in the occurrence and development of cervical cancer.
