BACKGROUND:Due to the emergence of drug-resistant tuberculosis and mismanagement in tuberculosis patients,the incidence of delayed healing or recurrent after spinal tuberculosis surgery is gradualy increasing,especialy in strongly predisposal children.Therefore,exploring the risk factors of delayed healing orpost-operative recurrence in pediatric patients after spinal tuberculosis surgery,wil have significance in the prevention and treatment of tuberculosis.OBJECTIVE:To analyze the risk factors of delayed healing or post-operative recurrence in pediatric spinal tuberculosis,and evaluate the efficacy of individualized re-operation.METHODS:From June 1998 to June 2013,clinical data of 145 pediatric patients with spinal tuberculosis were reviewed retrospectively,and some cases of delayed healing or post-operative recurrence in spinal tuberculosis were compared with other without delayed healing or post-operative recurrence.The patient's age,gender,nutritional condition,lesion debridement,history of chemotherapy and internal fixation,complicated spinal lesion,scope of lesions,preoperative erythrocyte sedimentation rate ＞60 mm/h,and postoperative complications were analyzed by Logistic regression analysis.The risk factors of delayed healing or post-operative recurrence were analyzed.After re-operation,erythrocyte sedimentation rate,C-reactive protein and imaging studies were detected.RESULTS AND CONCLUSION:After surgery,29 cases appeared delayed healing or post-operative recurrence and 12 of them received re-operation.The incidence of delayed healing or post-operative recurrence in pediatric spinal tuberculosis was 20％and the re-operation rate was 8.3％.Logistic regression analysis showed that,nutritional condition,history of chemotherapy,lesion debridement,and scope of lesions were significantly correlated with delayed healing or post-operative recurrence (P＜0.05).While patient's age,gender,history of internal fixation,complicated spinal lesion,preoperative erythrocyte sedimentation rate ＞60 mm/h,and postoperative complications had no correlation with the delayed healing or post-operative recurrence (P ＞0.05).Individualized re-operation can achieve good outcomes.Experimental findings indicate that,the risk factors of delayed healing or post-operative recurrence in pediatric spinal tuberculosis are very complex,enhancing the nutrition,complete debridement of lesions,and receiving chemotherapy can effectively decrease the incidence.According to the initial surgery and patient's conditions,individualized re-operation is the key to the success.

ObjectiveTo evaluate the effect of transureteroscopic Holmium:YAG laser lithotripsy on ureteral calculi.Methods105 cases of ureteral stones were treated by transureteroscopic Holmium:YAG laser lithotripsy. The transverses of stones were 4～15 mm and the vertical lengths were 5～25 mm.ResultsSuccessful lithotripsy was achieved on one session in 98 cases (95%), with the stones completely expelled within 2～6 weeks. Complications occurred in 4 cases and stones moved up in 3 cases.ConclusionThe transureteroscopic Holmium:YAG laser lithotripsy is an effective and safe method for ureteral calculi.

Objective To recommend the safety guidelines for workplace violence on health care sector according to the incidents of violence status on medical workplace.Methods A pilot study was conducted using a two-round Delphi method to study out the safety guidelines for hospital violence.Results In two subsequent rounds,the group discussed and screened out 50 entries from 51 items in the six modules as safety guidelines for hospital violence.Conclusions Establishment of safety guidelines for hospital violence on health care sector using Delphi method requires further clinical validation.

We report a spectrophotometic method for the determination of cyanogen chloride (CNCl) in air pollution.Experimental parameters for the stability and absorbility of CNCl gas in the different media were studied.The experimental conditions were optimized for CNCI as follows:absorbent:1%isonicotinic acid-barbituric acid;reaction acidity:pH 5.8 in phosphate buffer at room temperature;masking agent:0.01mol/L EDTA;λmax:598nm. The apparent molar absorptivity was found to be 1.17×105L·mol-1·cm-1,the linear range was within 0～5μg of CNCl in 25 mL solution; the regression equation of the curve has given by A=-0.0040+1.935C(r=0.9999).The method has been applied to the determination of CNCl in chimney gas,workshop air and production area air of the cyanuric trichloride plant,chemical works and pharmaceutical factory air.The relative standard deviation was below 2.7%(n=4)for the cyanogen chloride amount within 13～64mg/m3,and when CNCl amounts were within 0.1～1.0mg/m3,RSD was below 6.9%(n=6).The recovery was 98.7%.

Objective To reconstruct sparse views CT image based on defective projection data.Methods The position of bad bins in detector determined whether the linear interpolation was applied to the defective projection data.Moreover,reconstruction of air pixels in CT image was achieved rapidly and accurately.Results he experimental results showed that the proposed method could solve the problem from classical ART-TV method that the robustness was unstable due to the different positions of bad bin in CT detector.Conclusion Compared to analytical reconstruction methods,iterative methods can solve the reconstruction problems in this modality so that the radiologist is facilitated to perform image processing and quantitative analysis.

Objective To investigate the apoptosis induction effects and the possible mechanism of YM155 on triple negative breast cancer MDA-MB-231cells.Methods MDA-MB-231 cells were treated with dif-ferent concentrations of YM 155, and the survival rate of the cells was determined by CCK-8 assay and the half maximal inhibitory concentration ( IC50 ) value of YM155 was calculated .The apoptosis rate was examined by An-nexin V-FITC/PI double staining.mRNA expression of survivin and bcl-2 in MDA-MB-231cells was detected by RT-PCR.The protein expression of survivin , bcl-2, caspase-3, and PARP were detected by Western blot .Re-sults YM155 significantly inhibited the growth of MDA-MB-231 cells in a dose-and-time-dependenct way .IC50 was(1.749 ±0.265) ng/ml and(0.823 ±0.125) ng/ml respectively at 24 and 48 hours.The apoptosis rate of cells treated with 0.5 ng/ml, 1.0 ng/ml, and 1.5 ng/ml YM155 was (10.93 ±0.94)%,(31.10 ±1.51)%, and(46.83 ±2.92)%respectively, which had significant difference compared to that of the control group (6.4 ± 1.2)%(P<0.01).YM155 could significantly decrease mRNA and protein expression of surviving , besides, it reduced bcl-2 expression and increased caspase-3 and PARP protein expression .Conclusions YM155 can ef-fectively induce the apoptosis of MDA-MB-231 cells by downregulating survivin and activating caspase pathway . Bcl-2 might play a role in the apoptosis .

OBJECTIVE: To evaluate the therapeutic effect of Zangfukong suppository on the experimental vaginitis.METHODS:The experimental rats were equally assigned to 6 groups: normal control group,model control group,gyno-daktarin(0.12 g?kg-1) group,three Zangfukang groups(0.33 g,0.17,and 0.08 crude drug? kg-1).Candida albicans solution was injected into the vigina of the estrous rats to establish colpomycosis model.The effect of Zangfukang suppository on the infection rate of candida albicans was observed.The bacterial vaginitis model was established by injecting the mixture bacteria of Neisseria gonorrhoeae,staphylococcus aureus and escherichia coli into the vagina of rats,and the effect of Zangfukang suppository on the gonococcal infection rate.RESULTS: After local application of Zangfukang suppository for 7 consecutive days for treatment of colpitis mycotica of rats,the infection rates of candida albicans were significantly lower in medium-dose and high-dose groups than in the model control group(P
