Objective:Evaluate the relationship of complications and indwelling time of double-J ureteral stents after ureterscopic holmium-laser lithotripsy. Methods:170 patients were divided into two groups randomly. groupⅠ(stents indwelling 4 weeks),groupⅡ(stents indwelling 2 weeks).Complications of two groups were compared. Results:During the indwelling time,two groups presented urinary irritative sypmtoms were 81(93%)and 51(61%)P

AIM: To observe the adverse effect and clinical efficiency of Y-shape plate internal fixation for treating comminuted distal humeral fracture. METHODS: A retrospective analysis was conducted in 18 patients with the comminuted distal humeral fracture,who were admitted in the First Affiliated Hospital of Nanyang Medical College from January 2003 to December 2006. All patients were treated with Y-shape stainless steel or Ti-alloy plate in 3-7 holes,then the response of materials and host was observed. The curative efficiency was assayed with Cassebaum score,and the healing of fractures was detected with X-ray film. During follow-ups,the pain and joint motion were observed. RESULTS: The mean operational time was 134 minutes,the mean value of intraoperative blood loss was 172 mL,and all the incisions were healed well. All the patients were followed up for 6 months,and the mean time for the fracture healing was 14 weeks. One case appeared delayed healing in the resection lesion,and Kirschner's wire was loosened in 2 cases. There was no infection,local inflammatory reaction or rejection reaction occurred. Among 18 patients,11 got excellent results,4 good,2 fair,1 poor,and the rate of excellent and good efficiency was 83.3%. CONCLUSION: Y-shape plate after implantation shows good biocompatibility with the human body,with the manifestations of good reduction of comminuted distal humeral fracture,firm internal fixation,and satisfactory functional recovery of elbow joint.

Objective To compare the content of polysaccharide in Herba Scutellariae Barbatae derived from different places. Method Anthrone-sulphuric acid colrimetry was used. Result The contents of polysaccharide in Herba Scutellariae Barbatae derived from Mojiang Yunnan, Nantong Jiangsu, Huaning Hunan, Yongding Fujian, Lixin Anhui, Jiaoling Guangdong, Nanchang Jiangxi, Longsheng Guangxi, Honghu Hubei and Qingyuan Zhejiang were 8.12%, 7.61%, 6.61%, 6.07%, 5.84%, 4.61%, 3.15%, 2.69%, 2.65% and 2.34%, respectively. Conclusion The content of polysaccharide in Herba Scutellariae Barbatae from different places is quite different, and the highest is the one from Mojiang Yunnan.

Objective:To investigate the mechanism of ursolic acid inducing the apoptosis of human nasopharyngeal carcinoma cell line CNE-2Z.Methods:CNE-2Z were treated by ursolic acid with different concentration.Cell proliferation was determined by MTT assay.Cell cycle and apoptosis rate were analysed by flow cytometry(FCM).The expressions of bax,bcl-2 and cox-2 were assessed by SP method of immunocytochemistry,while the expression of caspase 3 by Western blot.Results:Ursolic acid inhibited the proliferation of CNE-2Z cells and induced the apoptosis in dosage and time dependent manner.FCM showed that the cell population reduced in S phase and cell cycle was arrested in G0/G1 phase.Immunocytochemistry showed that the expression of bax was up-regulated in the apoptosis,while the expression of bcl-2 and cox-2 down-regulated.Western blot showed that the expression of caspase 3 was strengthened.Conclusion:Ursolic acid can induce apoptosis of CNE-2Z in vitro.Its molecular mechanism probably is through promoting activation of caspase3,up-regulating the expression of bax,and down-regulating the expressions of bcl-2 and cox-2.

Objective To compare the content of saponin in Bark of Silktree Albizziae and Bark of Silktree Albizziae kaldora derived from different collection periods.Method Spectrophotometry was used to determine the contents of saponin.Result The contents of saponin in one-year Bark of Silktree Albizziae is different from two-year Bark of Silktree Albizziae(P0.05).The contents of saponin in multi-year Bark of Silktree Albizziae is different from multi-year Bark of Silktree Albizziae kaldora(P

Objective To present a new seriological method for diagnosing breast carcinoma.Methods Seral anti-p53 antibody was detected with immuno-polymerase chain reation(Immuno-PCR).The expression of p53 in tissue was detected with enzymeimmu-nohistochemistry technique.Results The positive rate of anti-p53 antibody in serum of breast carcinoma was 39.5% and anti-p53 antibody was not found in non-carcinoma and normal controls.The positive rate of anti-p53 antibody was higher than that of non-carcinoma and normal controls(P

OBJECTIVE: To promote Chinese pharmaceutical enterprises to understand their social responsibility clearly and to fulfill it actively.METHODS: The category of social responsibility of pharmaceutical enterprises was analyzed as well as the main approaches to perform corporate social responsibility.RESULTS: Chinese pharmaceutical enterprises should figure out their responsibility to consumers,employees,investors,society,community and other stakeholders.In recent years,the approaches to perform social responsibility based on force system of law and regulations and the improvement of enterprises' consciousness.These are unfavorable to Chinese pharmaceutical enterprises to undertake social responsibility actively.CONCLUSION: There are two approaches to promote Chinese pharmaceutical enterprises to perform their social responsibility,which are external supervision and internal governance.

Objective To compare the content of total flavonoids in Herba Scutellarlae Barbatae derived from different places.Method UV metric method was used to determine the contents of total flavonoids of Herba Scutellarlae Barbatae from different regions.Result The contents of total flavonoids in Herba Scutellariae Barbatae derived from Nantong Jiangsu,Juaoling Guangdong,Lixin Anhui,Huaning Hunan, Mojiang Yunnan,Yongding Fujian,Nanchang Jiangxi,Longsheng Guangxi,Honghu Hubei and Qingyuan Zhejiang were 4.16%,3.55%,2.89%,2.78%,2.41%,2.22%,2.16%,1.98%,1.61% and 1.51%,respectively. Conclusion The content of total flavonoids in Herba Scutellariae Barbatae from different places is quite different,and the highest is the one from Nantong Jiangsu.

Objective: Metrological verification for the medical emergency vehicle terminal 3G system, in order to facilitate the accurate positioning, route correctly, timely treatment, high success rate, and increase the credibility and effectiveness of treatment process records provided in the verification process or perform the burden of adducing evidences for emergency first-aid course.
