OBJECTIVETo evaluate the safety and clinical outcomes of the novel simplified no-flip surgical approach to Shang Ring male circumcision in adults.

METHODSA total of 528 adult males, aged 18 - 58 (mean 35) years, 63 with phimosis and 465 with redundant prepuce, underwent no-flip Shang Ring circumcision with or without removal of the outer ring. The operation time and intraoperative blood loss were recorded and observations were made on such complications as postoperative bleeding, infection, edema, and wound dehiscence.

RESULTSThe operation time, intraoperative blood loss, and 2-hour postoperative pain score were (3.8 +/- 0.3) min, (0.6 +/- 0.1) ml, and 7.3 +/-0.3, respectively. Spontaneous ring detachment occurred at 21.6 +/- 2.1 days postoperatively in 12.7% of the patients (67/528) who had chosen not to remove the rings. Of those who preferred removal of the outer ring (87.3% [461/528]), none experienced any pain at the ring removal 7 days after the operation. Postoperative complications included infection in 3 cases (0.56%) and mild edema in 9 (1.70%), but no bleeding and wound dehiscence. Totally, 518 (98.1%) of the patients felt satisfied with the postoperative penile appearance.

CONCLUSIONNo-flip Shang Ring circumcision, with no need for removal of the inner ring, is a safe and simple approach for adult males, which is superior to conventional Shang Ring circumcision for requirement of fewer surgical instruments, shorter operation time, lower incidence of complications, and better satisfaction with the penile appearance. However, these advantages are to be further demonstrated by more randomized controlled trials.

AIM: To construct prokaryotic expression vector of His-tagged human IP-10 for further study of its biological function in the inflammatory response. METHODS: The coding sequence of IP-10 lacking signal peptide was amplified from human lung cDNA library by polymerase chain reaction (PCR) and the fragment was cloned into pET-14b plasmid for the construction of His-tagged fusion protein expressing vector, pET-14b/IP-10. After being identified by enzyme digestion and sequencing, the recombinant vector was transformed into a strain of E. coli, BL21 (DE_3). The expression of His-tagged fusion protein was induced with IPTG and purified with Ni+-NTA affinity chromatography. Then the chemotactic activity of IP-10 was determined by transwell migration assay on THP-1 cells. RESULTS: The construction of pET-14b/IP-10 recombinant vector was proved by enzyme digestion and sequencing. The fusion protein IP-10, which was purified by a routine Ni+ affinity method, had an activity on the induction of cell migration of THP-1. CONCLUSION: We successfully construct IP-10 fusion protein expressing vector and get the fusion protein with high bioactivity, which provides essential materials for the future studies on IP-10.

Objective:To compare the similarities and differences of doctor -patient trust building mechanism between doctors in urban and rural areas from the perspective of rural residents by the empirical study .Methods:Based on the field research and secondary in -depth interviews to the related personnel in H County of Beijing .Re-sults:There had obvious difference of doctor -patient trust building mechanism between doctors in urban and rural areas from the perspective of rural residents .Trust building mechanism between village doctors were mainly the trust of the similar social background , between the doctors in township health centers and city hospital were the trust based on reputation , institution-based trust , and relationship-based trust .Conclusion:The difference of re-gional and cultural between urban and rural areas ,the nature of medical institutions the relationship with doctors , reputation of medical institution and medical and health care system in urban and rural areas ,maybe the reasons that The difference of doctor -patient trust building mechanism between doctors in urban and rural areas .

Objective To establish a stable HCV full-length genome replication cell model which is labeled with reporter gene and easyly to quantify intracellular HCV proteins and RNA level. Methodsneo gene was inserted into Luc-JC1 to make Luc-JC construct. Luc-JC RNA was obtained by in vitro transcription and then delivered into Huh7 cells by transfection. G418-resistant clones of Huh7 cells were obtained by selection. Clones of HCV full-length genome replication cell were confirmed by luciferase activity assay, Western blot and cleaveage of eYFP-MAVS by HCV NS3/4A protease. Then, HCV replication cell colonies were treated by different dose IFN-α in order to observe the change of luciferase activity, HCV protein and RNA level. Results At 3-4 weeks post-transfection, visible colonies were selected and stained by crystal violet. Luciferase activity and HCV NS3, NS5A protein were detected by luciferase activity assay and Western blot, respectively. Subcellular localization of eYFP-MAVS transferred from mitochondria to cytoplasms by cleavage of NS3/4A protease in cell colonies. Luciferase activity, HCV protein and RNA diminished obviously after IFN-α treatment. Conclusion A stable HCV full-length genome replication cell model labeled by reporter gene was successfully established and reporter activity can be used to indicate level of HCV proteins and RNA in cells. This cell model is a useful tool for the study on HCV pathogenesis and the screening of antiviral drugs.

Objective To produce a novel tool for breaking off the ampoule bottles,which can protect the nurses from wounding their fingers by the glass fragment so as to guarantee the safety for the nurses. Methods We design a mould with the self curing plastic and leave some space in the end to insert the ampoule bottle,then fix the bistrique and spring to break off the bottles. Results This tool can break off several kinds of ampoule bottles with any bottles cracked and has achieved good clinical effect. Conclusion This mulfunctional tool is scientificly designed,easy to make,and it is very helpful for the medical staff in protection and enhancing working efficiency,so it is very valuable to be popularized in hospitals.

Objective To learn from various view points the team building of rural doctors in Beijing.Methods 84 village officials,rural doctors and villagers were enrolled from three townships in district H of Beijing,for an interview to learn the makeup and selection approach of rural doctors,and their recommendations on team building of these doctors.Results 76.19% of the interviewees prefer their own villagers as candidates for their rural doctor.Top three factors for their retention were their medical competence,geo-relations,and service attitude;60.71% of the interviewees held that the village committee should be the decision maker for appointment of rural doctors; in terms of team building,senior doctors emphasize retirement conditions,while new ones prefer training opportunities.Conclusions The topmost criterion for rural doctor candidates should be their medical competence,instead of sacrificing this criterion for geo-relations.The village committee and the villagers' congress should play a greater role of supervision and management of the rural doctors.Targeted incentives are recommended for the rural doctors in view of their retention.
