Objective To observe the clinical curative effects of shengmai injection on shock.Methods Seventy-one patients with shock were randomly divided into two groups.The control group(35 cases) was treated with general treatment of western medicine.On the basis of above treatment,the integrated traditional Chinese and western medicine treatment group(TCM WM group,36 cases) was treated with shengmai injection 30 ml diluted by 5%glucose 250 ml intravenous drip 2 times a day for 3-5 days.Results In TCM WM group,the vanishing times of breath rate,heart rate,blood pressure and urinary volume were significantly shorter(all P

ObjectiveTo investigate the effect of different cyclic strengths on expressions of phospholipase A2 (PLA2) and cyclooxygenase (COX) in human tenocytes.MethodsHuman tenocytes were uniaxially stretched with different stretching intensity (4％, 8％ and 12％) under 0.5 Hz for four hours.Non-stretched tenocytes were applied to the control group.The expressions of cytosolic PLA2(cPLA2), COX1 and COX2 were measured by Western blot and RT-PCR.The secretion of secretory PLA2 (sPLA2) was measured by ELISA.Results The mRNA expressions of cPLA2, COX1 and COX2 in control group, 4％, 8％ and 12％ stretch groups showed an increase trend.But protein expressions of cPLA2 and COX1 in 4％ stretch group were increased insignificantly compared with the control group (P ＞ 0.05).Protein expressions of cPLA2 and COX1 in 8％ and 12％ stretch groups were increased more significantly compared with the control group (P ＜ 0.01).The COX2 expression in 4％,8％ and 12％ stretch groups showed statistical difference compared with that in the control group (P ＜0.01) and the difference increased with stretch intensity.There was no different expression of sPLA2 between 4％ stretch group and control group (P = 0.260).However, expression of sPLA2 was increased markedly in 8％ and 12％ stretch groups (P ＜ 0.01).ConclusionsThe expressions of human tendnocytes PLA2, COX1 and COX2 in vitro are positively correlated with stretch intensity.PLA2/COX system may be a new molecule target in clinical treatment of tendinopathy.

ObjectiveTo evaluate the clinical results of minimally invasive ankle arthrodesis with percutaneous cannulated screws.MethodsBetween April 2005 and October 2010, 12 patients with the ankle arthrodesis for unilateral severe arthritis (Kellgren-Lawrence class Ⅲ) were prospectively analyzed, including 2 cases of rheumatoid arthritis, 8 cases of post-traumatic arthritis, and 2 cases of osteoarthritis. There were 7 males and 5 females with an average age of 42.0 years(range, 25-7 1). The average disease duration was 7.3 years (range, 1-21). The anterior median incision of 3.0-5.0 cm was made to explore the ankle joint.The cartilage of tibial-talus joint was completely debrided. Two guide pins were inserted from posterosuperior to anteroinferior, and cannulated screws were implanted to fix ankle joint. All patients were physically examined with an extended protocol of questionnaires and the American Orthopaedic Foot and Ankle Society (AOFAS) Ankle and Hindfoot Scales. Ankle fusion in all patients was evaluated by clinical examination, and conventional radiography including anterior-posterior, lateral and mortise views of the ankle. ResultsAll 12 patients were followed up postoperatively for an average of 21.5 months(range, 6-55), and were proved be bone union by clinical examination and radiology with a mean of 13.5 weeks (range, 9-21). The AOFAS rating scale improved from a mean of 42.8±8.6 points at pre-operation to a mean of 66.6±5.4 points at post-operation 6 months,showing significant difference(t=-3.075, P=O.012), and to a mean of 72.3±4.6 at the final follow-up, also showing significant difference with pre-operation (t=-8.595, P=-0.006). There was no infection,local skin necrosis, screw loosing, and so on. ConclusionThe minimally invasive ankle arthrodesis with percutaneous cannulated scews is a recommend procedure, with mini-invasion, short surgery time, high fusion rate, good clinical outcomes, few complications.

Objective　To study the effect and safety of radiofrequency ablation (RFA) in the treatment of liver cancer.Methods　The clinical data of prospectively and non-randomly selected 102 liver cancer patients were analysed. Results　102 patients with a total of 216 tumors were found in this series, the size of hepatomas were 1.5 to 14*!cm in diameter (average 4.9*!cm in diameter). In 67 of primary liver hepatocellular carcinoma, the tumors' size were smaller than 5*!cm in diameter in 21 cases; 35 with secondary liver tumors. RFA were performed under the guidance of ultrasonography in 43 cases, under CT in 50, under laparoscopy in 3, and 6 were performed during open surgery. All patients received ultrasonography and CT scanning of liver one month after the ablaton. The echoes of the tumors were stronger, and the area of the echo reached was larger than pre-ablation; blood flow in the tumor obviously reduced and even disappeared in sonography; CT showed that the shadow density in the tumor was diminished. Of the 102 patients, 14 underwent 18-FDG-PET imaging 30 days after the ablation, of them, 11 showed defect of radiation in the tumor, 3 showed residual locus in the tumor. 2 of the 3 cases underwent RFA again and the residual was disappeared completely, the another subject to ethanol injection because of advanced age. All the patients were followed up for 3-18 months. Except 6 patients with late metastastic liver cancer died within 1 year after RFA, the other 96 cases remained alive now, the 1-year survival rate was 94.1%. Conclusions　RFA is a new ideal therapy for liver cancer. It is safe, effective, and good tolerance with little trauma.

OBJECTIVE: To constitute school sanitation standard using modified Delphi method, and to explore the feasibility and the predominance of Delphi method in the constitution of school sanitation standard. METHODS: Two rounds of expert consultations were adopted in this study. The data were analyzed with SPSS15.0 to screen indices of school sanitation standard. RESULTS: Thirty-two experts accomplished the 2 rounds of consultations. The average length of expert service was (24.69 ±8.53) years. The authority coefficient was 0.729 ±0.172. The expert positive coefficient was 94.12% (32/34) in the first round and 100% (32/32) in the second round. The harmonious coefficients of importance, feasibility and rationality in the second round were 0.493 (P<0.05), 0.527 (P<0.01), and 0.535 (P<0.01), respectively, suggesting unanimous expert opinions. According to the second round of consultation, 38 indices were included in the framework. CONCLUSION Theoretical analysis, literature review, investigation and so on are generally used in health standard constitution currently. Delphi method is a rapid, effective and feasible method in this field.

Objective:The study aimed to investigate the effects of exercise on the expression of ferroptosis-related proteins and the associated mechanisms in a post-traumatic stress disorder(PTSD)model induced by transient foot shock.Methods:Thirty-five male C57BL/6J mice(8 weeks old)were randomly divided into three groups:Control group,PTSD group,and Exe+PTSD group.PTSD model mice were established by foot-shock and PTSD behaviors were assessed using a fear conditioning box.Iron distribution areas were detected by Fe3+staining.Western Blot analysis were performed to determine the expression level of ferroptosis-related proteins in the mice.Results:Compared to the control group,the freezing time and Fe3+distribution areas in the cortex and hippocampus were significantly increased in the mice with PTSD(P＜0.05).The levels of ferroportin1(FPN1),glutathione peroxidase 4(GPX4),and brain-derived neurotrophic factor(BDNF)proteins were significantly decreased(P＜0.05),while the expression of high mobility group box 1(HMGB1)protein was significantly elevated(P＜0.05).Exercise significantly reduced freezing time and Fe3+accumulation in the cortex and hippocampus(P＜0.05),and it also up-regulated the expression of FPN1,GPX4,and BDNF proteins(P＜0.05),while down-regulating HMGB1 expression compared to the PTSD group(P＜0.05).Conclusion:This study demonstrates that PTSD induces the ferroptosis-related pathway in mice,and exercise can inhibit iron accumulation and reverse the expression of ferroptosis-related proteins induced by PTSD,there-by alleviating PTSD-like behavior in mice.
