Objective To investigate the efficacy of minimally invasive treatment by combination of external fixation with limited internal fixation for unstable distal radius fractures. Methods From September 2003 to September 2007,43 patients with unstable distal radius fractures were treated with external fixation combined with Kirschner wire fixation. According to AO classification,there were 10 cases of C1,21 cases of C2,and 12 cases of C3. Two external fixation clamp stand screws were inserted into the dorsal radius in operation,then external clamp stand was fixed when manipulative reduction were performed after C-arm perspective. The broken bones were sledged by Kirschner wire when articular facet and bone block were not peaceful and could not achieve reduction by traction. When the bone block was instable,a Kirschner wire fixation was needed. Bone graft through a limited incision were performed for bone defect if necessary. Results All of the 43 cases achieved anatomical reduction after the operation. The mean operaton time was 62.4 min (range from 43 to 121 min). And the mean intraoperative blood loss was 15.3 ml (ranged from 6 to 30 ml). The patients were discharged from hospital in 3 to 14 days with a mean of 5.5 days. After being discharged,they were followed up for 6 to 24 months (mean,12 months),during which,re-examination showed bone union and improved articular activities in all the cases. According to the Dienst scale system,30 patients achieved excellent,8 were good,and 5 were fair. The rate of excellent and good results was 88.4% (38/43). Conclusion External fixation combined with limited internal fixation is a simple,reliable and effective method for treatment of the unstable distal radius fractures.

Objective To detect the change of discharge phase of guinea pig hippocampal CA1 pyramidal cells during visual discriminative task with an effective and convenient program we designed. Methods Five guinea pigs were performed by extracellular single unit recording in vivo when they were performing visual discriminative task. Discharge signals of individual pyramidal cells were extracted from different frequency signals by wavelet transform (WT), which made it feasible to calculate discharge phase of pyramidal cells in terms of time correlation between discharge and ? rhythm. Results The discharge phase of CA1 pyramidal cells in the 1 to 5s interval before visual discriminative task (172??1.8?) was obviously earlier than that in the 6 to 10s interval after visual discriminative task (189??3.7?) ( P0.01). Conclusion The program we designed is capable of detecting discharge phase of pyramidal cells. Regular shift of discharge phase of hippocampal CA1 pyramidal cells emerges before and after performing visual discriminative task.

Objective To assess the current situation and quality of clinical randomized controlled trials(RCTs) designed for accessing the treatment of depressive neurosis with acupuncture and moxibustion. Methods Relative clinical research literatures published from year 1980 to 2008 were collected, and composed into "evaluation to all literature of acupuncture and moxibustion treating depressive neurosis message table", according to the clinical epidemic disease and EBM. The quality evaluation on these trails were performed. Results There were altogether 15 articles included in this study. Among them, 5 articles used the correct randomized controlled trials (33.3%), 10 articles used the diagnostic criteria (66.6%), 10 articles used excluded criteria (66.6%), 12 articles used the therapeutic evaluation criteria (80%), 4 articles used blind treals (26.7%), 5 articles reported quit cases (33.3%), and 9 articles reported the adopted statistical methods (60%)4 articles Conclusion The quality of RCT of acupuncture and moxibustion for depressive neurosis needs to be improved.

Objective To investigate the efficiency of meropenem in treating secondary peritonitis in newborn infant. Methods Twenty-four newborn infants with secondary peritonitis were treated by meropenem from January 2006 to June 2009 in Tianjin Childrens Hospital. The therapeutic effects were evaluated in the 24 cases. Results Twenty-one patients revealed positive of germiculture and 30 germ strains were isolated from the culture. After the treatment with meropenem, complete cure were observed in 21 newborns. One case gave up treatment,and the other two died. Overall bacterial clearance rate was 86. 7%. Both the clinical cure rate and the total cure rate were 87.5%. The clinical effect consisted with bacteriological effect. Conclusions Meropenem is effective and safe in the treatment of secondary peritonitis in newborn infant.

Microbiology is an important,fundamental and obligatory course in contemporary life science.This article introduces that teaching group of microbiology in Nankai University realizes transformation of teaching center,fully embodies the modernization of teaching notion and gives full play to students' main effect practically by adhering to teaching reform as center,optimizing teaching method as measure,communicating in and after class and using multi-media and teaching web.Therefore,teaching system is established to adapt to modern teaching notion and eventually microbiology course becomes a cultivation platform to foster elites with both solid fundamental theory and innovating mind.

Objective To systematically compare the efficacy of three-dimensional conformal radiotherapy (3D-CRT) versus intensity-modulated radiotherapy (IMRT) in the treatment of prostate cancer (PCa).Methods Clinical comparative studies of IMRT and 3D-CRT in the treatment of PCa were collected from PubMed, EMBASE, China National Knowledge Infrastructure (CNKI), and Wanfang Data after two independent researchers developed the strategy and inclusion and exclusion criteria for the literature search.Articles published up to February 2017 were searched for, and the languages of publications were restricted to English and Chinese.Clinical meta-analysis of the data from the relevant studies was performed using the RevMan5.3 software.Results A total of 15 relevant retrospective cohort studies were collected from the databases in strict accordance to the search strategy and inclusion and excluding criteria.There were 4608 PCa patients, including 2229 in the IMRT group and 2379 in the 3D-CRT group.IMRT and 3D-CRT had similar adverse effects in terms of early-stage (odds ratio[OR]=0.77, 95% confidence interval[CI]:0.43-1.40, P=0.390) and late-stage (OR=0.75, 95%CI:0.55-1.04, P=0.080) urinary tract injury.However, IMRT led to reduced early-stage (OR=0.47, 95%CI:0.27-0.82, P=0.008) and late-stage (OR=0.52, 95%CI:0.35-0.78, P=0.001) intestinal injury compared with 3D-CRT.Meanwhile, the biochemical recurrence-free survival rate was also significantly higher in the IMRT group than in the 3D-CRT group (OR=1.87, 95%CI:1.51-2.32, P=0.000).Conclusions IMRT is more protective against intestinal injury with a higher biochemical recurrence-free survival rate compared with 3D-CRT during the treatment of PCa.
