Objective To discuss the operation style of filling,film-style,three-dimensional double-layer mesh tension-free for hernia and the repair materials,the selectlon of surgical operation style for reducing recurrence.Methods We used the style of plug-and-chip,two-dimensional mesh tension-free hernia repair for the treatment of 130 cases of inguinal hernia patients.Results In 130 cases of patients with 1~5 years of follow-up,there was no recurrence.Conclusion A reasonable choice of repair materials and improving the surgical operation can be effective in reducing recurrence.

Objective To investigate the concentration change of indoxyl sulfate (IS) in blood and the renal expression of renal fibrosis-related factors (transforming growth factor-beta 1, TGF-β1;fibronectin, FN) after administration of mutagenic lactobacilli by oral.Methods A total of 60 male Sprague-Dawley (SD) rats aged 6 weeks was divided randomly into 3 groups.The normal control group (Sham group, n =20) received Sham operation of just incision of skin without kidney removed.The other two groups of rats were renal failure models selected from survivals of the other 40 rats who received real operation with 5/6 of kidney removed.Finally, 35 survived renal-failure rats were divided randomly into 2 groups : pathological control group(Model group, n =17) who were administrated of 2ml sterile saline solution once a day by gavage, and experimental group (lactobacillus bulgaricus (LB) group, n =18) who were administrated of 2 ml mutagenic lactobacilli (1.5 × 108 cfu/ml) once a day by gavage.Eight weeks later, blood specimens were taken to test the concentration of IS with high performance liquid chromatography-fluorescence detection (HPLC-FLU), and urea and creatinine by automatic biochemical analyzer;moreover, the rats were killed to get kidney tissues for pathological examination.Results The levels of serum IS, urea, and creatinine were statistically significantly different between two groups (P ＜ 0.05).Both the levels of renal tubular damage and renal interstitial fibrosis were both lessen in the experimental group compared to the model group (P ＜0.05).TGF-β1 and FN expressions in renal tissues were significantly decreased (P ＜0.05).Conclusions Mutagenic lactobacilli not only reduces serum concentration of IS, urea and creatinine in renal failure rats but lowers the expressions of TGF-β1 and FN in renal tissues.

ObjectiveTo determine the dose of butorphanol at which 50％ and 95％ effective dose (ED50 and ED95) of patients inhibition uterine contraction pain on analgesic artificial abortion.Methods Twenty-six patients undergoing analgesic artificial abortion were sequentially given different doses butorphanol so that the ED50 and ED95 could be determined by up-and-down sequential test.Anesthetic depth was observed when giving propofol with 200 mg/min speed,uterine contraction pain at awaking immediately,10,20 min after awaleing.Data was analyzed by Probit regression analysis for calculating ED50 and ED95..ResultsButorphanol could restrain uterine contraction pain on analgesic artificial abortion and the ED50 was 246 μg with the 95％ confidence interval of 201 μg to 281 μg,the ED95 was 324 μg with the 95％ confidence interval of 287 μg to 548 μg.ConclusionED50 and ED95 value can be expected as a parameter to optimize analgesic artificial abortion.

Objective To settle the "bottleneck" disputes existed in the key aspect of emergency treatment care of emergency department, long delayed time of medical workers or patients, perplexity of first-aid personnel, less standard in medical records. Methods Comparison experiment was carried out with the traditional model of emergency care in contrast with the new model, besides the service attitude was improved,the awareness of responsibility was strengthened and the first-aid technique was increased. Number of nursing errors and disputes, hospitalization time, satisfaction degree of patients and record trace-ability were observed. Results The nursing errors and disputes reduced by 46%, hospitalization time re-duced by an average of (7.2±0.2) minutes, satisfaction degree of patients increased by 10.99%, leaving 1673 record traceability of care. Conclusions The application of new management processes of nursing interface in emergency department can settle the "bottleneck" disputes of key interface, make the green passage of emergency patients more convenient and is conducive to safe care, less mortality, high work effi-ciency, which proves to be a reference for fellows.

Background and purpose:Adenosine triphosphate-binding cassette superfamily G member 2 (ABCG2), which has been found over-expressed in a variety of cancer cells, takes part in the drug resistance of cancer through effux of anticancer drugs. The purpose of this study was to investigate the mechanisms of human glioblastoma cells sensitivity to pyropheophorbide-a methyl ester (MPPa)-mediated photodynamic therapy (PDT) eradicating tumour cells and its relationship to ABCG2.Methods:U87 and A172 glioma cell lines in the logarithmic growth phase were selected and exposed to the treatment of MPPa-PDT and MPPa-PDT+fumitremorgin C (FTC) respectively. The cell viability was measured with the use of CCK-8 assay. The expression of ABCG2 was detected by Western blot. The intracellular contents of MPPa in each group without illumination were tested by lfow cytometry. Flow cytometry with AnnexinⅤ-FITC/PI double staining was used to detect the cell apoptotic rate. DCFH-DA staining was used to assess the generation of intracellular reactive oxygen species (ROS).Results:The MPPa-mediated PDT could eradicate A172 and U87 cancer cells in an energy-dependent manner. The light energy density in A172 was 8 times of that in U87 when the cell viability reached median lethal dose after MPPa-mediated PDT. The high expression of ABCG2 in A172 cells affected the accumulation of intracellular MPPa. Inhibition of ABCG2, not only could enhance the eradicating effect of MPPa-PDT on A172 cells, but also could increase the yield of ROS triggered by MPPa-PDT and the accumulation of intracellular MPPa.Conclusion:The human glioblastoma cell line A172 is insensitive to MPPa-mediated PDT. The mechanism may relate to ABCG2, which decreases the MPPa content in cancer cells through effux of MPPa, resulting in decline of cytotoxicity.
