OBJECTIVE:To provide reference for the rational use of TCM injections. METHODS:The related data of using TCM injections was drawn from May 2009 to May 2014. And the data of 5 TCM injections,including Shengmai and Shenmai in-jection,were statistically analyzed,the indications of 8 TCM injections,including Shengmai and Shenmai injection,were also sta-tistically analyzed. RESULTS:In solvents evaluation,the 5 TCM injections were used 501 times,in which 391 times(78.04%)of the solvents used were rational,381 times(76.05%)of the solvent doses used were rational;in clinical indications evaluation,the 8 TCM injections were used for 2 579 patients,in which 1 120 cases were in accordance with the instructions while the other 1 459 cases were not,the qualification ratio was 43.43%. CONCLUSIONS:There were still some problems in using TCM injection in our hospital in the aspects of solvent as well as indications.

Objective To probe into the characteristics of men who have sex with men living in small-medium sized cities and provide scientific foundation for the formulation of strategy for AIDS prevention and control.Methods A qualitative survey was carried out by convenience sampling for thirty one selected MSM.Results Interviewees had a large age gap,widely different occupations and various degrees of education;they depended mainly on internet and friends' contacts to find their sex partners;their knowledge about HIV/STDs was poor and they were indifferent to the risk of AIDs,but were faced with enormous psychological pressure.Multiple sex partners,unprotected anal intercourse were their main high risk behaviors,and they hoped to have access to free condoms,free HIV detection and hot line consultation.Conclusion To implement prevention in an effective manner,close attention should be paid to the role of key persons within the MSM group,to increasing knowledge of the target population,to protecting their mental health and to creating a friendly social environment for their existence and effective use of internet.

Objective To investigate the clinical results, indications and choices of surgical treatment of minimally invasive internal fixation by cannulated compression screws in the treatment of femoral neck fractures. Methods The authors retrospectively analyzed clinical data of 83 patients with femoral neck fractures treated by minimally invasive internal fixation by AO cannulated screws. Results According to the Garden classification, the patients comprised 12 cases of type I, 39 cases of type II, 23 type III and 9 type IV. The mean time from injury to surgery was 63.4 hours, the mean operation time was 65.7 min, the mean intraoperative blood loss was 64 ml and the mean hospital stay was 7.7 days. No wound infection, deep venous thrombosis of leg, pulmonary embolism or breakage of internal fixation occurred. No patients died. Follow-up observation ranged 12～48 months, with a mean of 31.3 months. Normal bone union was obtained in all the cases. Postoperatively, shortening of femoral neck took place in 4 patients (4/83, 4.8%) and different degrees of osteonecrosis happened in 7 patients (7/83, 8.4%). The mean postoperative Harris hip score was 94.6. Conclusions Minimally invasive internal fixation by cannulated compression screws for femoral neck fractures may be an effective alternative. This method is indicated for Garden I/II fractures without displacement in patients above 65 years old, or any types of femoral neck fractures in patients below 65 years old.

Objective To investigate the clinical results of minimally invasive plate fixation for tibial plateau fractures. Methods Minimally invasive plate fixation was adopted in 26 cases of tibial plateau fractures from January 2000 to June 2003. Results Follow-up for 6 months ～ 4 years (mean, 2 1 years) showed bone union in all the patients. The results of therapy were assessed according to the Merchant criteria as follows: excellent in 20, good in 5 and fair in 1. Conclusions Minimally invasive plate fixation in the management of tibial plateau fractures has advantages of minimal trauma, reliable fixation, early movement and fewer complications, being a valuable clinical alternative.

Objective To explore the surgical result of unilateral half-pin external fixation in the treatment of distal tibial fracture. Methods For type A fracture, two pins were inserted into the proximal fragment of tibia fracture and another two pins into the distal fragment; for type B and C fracture, distal pins were inserted into the talus and calcaneus. The fracture reduction was performed by distraction of external fixators. A limited open reduction was required in some difficult cases to restore the joint surface, with bone grafting and small fragments fixed with wires or screws. Meanwhile, fracture of fibula was fixed with plate and screws. Results The duration of external fixation was 3.5~8 months (mean, 5 months) in 22 patients. Bone union was achieved in all patients, without serious deep infection, osteomyelitis, or non-union. The patients were followed for 10~32 months (mean, 20 months). Functional exercise was carried out for more than 6 months after the removal of the external fixator. According to the Tornetta’s evaluation standard, excellent results were obtained in 11 patients, good in 7 patients, fair in 3, and poor in 1. Conclusions Unilateral half-pin external fixation combined with limited open reduction and internal fixation is a simple and effective minimally invasive method for the treatment of distal tibial fracture.

Objective To investigate the role of mitochondrial KATP channel in the mechanism of the protective effect of ischemic preconditioning (IP) against ischemia-reperfusion (I/R) injury.Methods Forty-eight Wistar rats of both sexs weighing 250-350 g were used in this study. Forty rats were randomly divided into 5 groups ( n = 8 each): group A I/R; group B IP+ I/R; group C diazoxide (DZ mito-KATP channel activator) + I/R; group D 5-HD (mito-KATP channel blocker) + IP + I/R and group E 5-HD + DZ + I/R. Another 8 animals were used for electron microscopic examination of normal mitochondria as control. The animals were anesthetized with intraperitoneal pentobarbital 30 mg?kg-1. The hearts were immediately excised and passively perfused in a Langendorff apparatus with K-H solution at 5.8 kPa perfusion pressure and 36.5-37.5℃ via aortic cannulation. A fluid-filled latex balloon was via left atrium in left ventricle for the measurement of left ventricular function. I/R was induced after 30 min stabilization by clamping aortic cannula for 40 min followed by 30 min reperfusion. In group B and D the isolated hearts underwent 2 episodes of 5 min ischemia followed by 5 min reperfusion before I/R. In group C and E DZ 50 ?mol?L-1 was infused for 10 min and in group D and E 5-HD 100 ?mol?L-1 was infused for 10 min before I/R. HR, LVSP, LVEDP and coronary flow (CF) were measured at the end of stabilization (T0 , baseline), immediately before I/R (T1 ) and at 10, 20 and 30 min of reperfusion (T2.3.4.), and left ventricular developed pressure (LVDP= LVSP- LVEDP) was calculated. Myocardial tissue was obtained at the end of 30 min reperfusion for electron microscopic examination of mitochondria. Mitochondrial ultrastructure was assessed by Flameng scoring system (0 = normal, 4 = severely damaged) .Results Ischemic and DZ preconditioning significantly increased LVDP and decreased LVEDP and Flameng score. 5-HD pretreatment partly antagonized the protective effect of IP and completely antagonized that of DZ against I/R injury. Conclusion Ischemic preconditioning protects the heart against I/R injury mainly by activating mitochondrial KATP channel.
