BACKGROUND:There is no consensus on the choice of anatomic plate or dynamic hip screw for the treatment of intertrochanteric fracture. Current research is limited to smal-sample studies, and it is difficult to carry out a large-sample multicenter analysis. OBJECTIVE:To carry out Meta-analysis about the literature on anatomic plate versus dynamic hip screw in the treatment of intertrochanteric fractures, in order to evaluate the efficacy of anatomic plate versus dynamic hip screw in the treatment of intertrochanteric fractures. METHODS:The PubMed database (1995-2013), EMCC database (1995-2013), CBM database (1995-2013), CNKI database (1995-2013), VIP database (1989-2013) and Wanfang database (1995-2013) were searched by computer to col ect the control ed trials of anatomic plate versus dynamic hip screw for the treatment of intertrochanteric fractures. Then, the retrieved studies were screened according to predefined inclusion and exclusion criteria. The quality of the included studies was evaluated to extract useful y data, and Meta-analysis was performed by using the RevMan5.0 software. RESULTS AND CONCLUSION:A total of 19 control ed trials were included with a total of 1 730 cases. Among them, 764 cases were belonged to the anatomic plate group, and dynamic hip screw group included 966 cases. The Meta-analysis results indicated that there were no statistical y significant differences in fracture healing time, prognosis excellent and good rate and postoperative complications between two groups (P=0.34, 0.58, 0.80);the operative time, intraoperative blood loss and postoperative drainage volume in the anatomic plate group were lower than those in the dynamic hip screw group (P<0.000 01). The results indicate that anatomic plate and dynamic hip screw have the similar clinical efficacy for the treatment of intertrochanteric fractures, but the anatomical plate has relatively simple operation and less bleeding. Due to the poor quality of the included literatures and high bias occur and influence the effect, so more wel-designed multi-center randomized control ed trials should be performed to provide high-quality evidence.

Objective To study the effect of erythropoietin(EPO) on PI3-K/Akt signal pathway of myocardial ischemia-reperfusion injury(I/R) in immature rabbits. Methods Thirty immature rabbits were randomly divided into two groups (n = 15/greup ), The rabbits were intraperi- toneally injected with 2 ml of normal saline in control group, or 5 000 U/kg of EPO in treated group 24 h before I/R. The Langendorff isolat- ed perfused heart model was established, and the myocardial expression of PI3K, AKT and Caspase 9 were examined by immunohistochem- istry in 2 h after repeffusion. To monitor the myocardial apoptosis,we performed TUNEL in 2 h after reperfusion. Results The expression of myocardial PI3K and AKT in EPO group was significantly higher in EPO-treated group than those in control group. In EPO-treated group, the expression of myocardial caspase 9 was significantly lower than that in control group. The average optical density of myocardial PI3K, AKT and caspase 9 were significantly different between both groups (P 〈 0.01 ).The number of apoptotic cell was significantly fewer in EPO- treated group than that in control group. The myocardial apoptosis index (AI)was significantly different between two groups (P 〈 0.01 ). Conclusion EPO pretreatment can influence the PI3-K/Akt signal pathway and decrease the myocardial apoptosis,and significantly reduce the myocardial ischemia-reperfusion(I/R) injury in immature rabbits.

Objective:To observe the impact of compound glycyrrhizin combined with triamcinolone acetonide on clinical effects and immune function in the patients with oral lichen planus ( OLP) . Methods:Totally 100 patients with OLP were randomly divided into the control group (50 cases) and the study group (50 cases). The control group was locally injected with triamcinolone acetonide, and the study group was treated with compound glycyrrhizin tablets additionally. The treatment course was 4 weeks. Visual analogue scale ( VAS) and REU scoring system were used to assess pain and symptoms of OLP, the clinical effects and cellular immune function were compared, and the adverse reactions were recorded as well. Results:After the treatment, the VAS score and REU score respec-tively lower than those for the control group, and there were differents between the two groups (P<0. 05). The total effective rate was 84. 0% in the study group, which was higher than that in the control group (66. 0%) (P<0. 05). The percentage of CD3+ and CD4+ cells was increased, that of CD19+ cells and the ratio of CD4+/CD8+ were decreased, and there were significant differences be-tween the two groups (P<0. 05). The adverse reactions in both groups were mild. Conclusion:Compound glycyrrhizin combined with triamcinolone acetonide is effective for OLP and can improve the immune function in the patients.

Objective: To evaluate the repair method and its curative effects on defects and joint instability in elderly patients with recurrent soft tissue sarcoma around the knee after wide excision. Methods:Our study included 6 elderly patients with limb sal-vage and effective preoperative chemotherapy. These patients underwent extended resections, including internal or lateral articular cap-sule and collateral ligament excisions. Owing to polyleptic soft-tissue sarcoma around the knee, formed soft-tissue defects, and joint in-stability, collateral ligament and/or partial articular capsule was reconstructed using #5 Ethibond sutures. Simultaneously, soft-tissue de-fects around the knee were repaired by composite-wide pedicled fasciocutaneous flaps or medial head of gastrocnemius muscle flaps of the leg. The maximum flexion angles of the knee (MFKs) were observed and statistically tested before and during surgery, with a fol-low-up period of 6 months. Results: The immediate stability of the joints and complete coverage of the soft tissue defects were achieved during the surgery. The MFKs during preoperative treatment, intraoperative treatment, and six-month follow-up were 115.0° ± 7.8°, 101.7° ± 9.3°, and 104.8° ± 10.2°, respectively, with significant differences between the preoperative and intraoperative MFKs (t=2.68, P<0.05). By contrast, no difference existed between the intraoperative and six-month follow-up MFKs (t=0.55, P>0.05). Conclu-sion:This repair method can be applied to elderly patients with polyleptic soft tissue sarcoma around the knee by using simple, fast, and reliable surgical techniques for the reconstruction, stability, and repair of soft tissue defects in the knee joint.

Objective To summarize the experience of tension-free repair for inguinal hernia in the preperitoneal space using modified surgical mesh. Methods From Dec 2008 to May 2010, 134 cases with 138 reducible primary inguinal hernia were randomly divided into two groups. Sixty-seven patients (70 hernias) in the study group underwent tension-free repair in the preperitoneal space by modified surgical mesh, while the control group (67 cases, 68 hernias) underwent Rutkow's herniorrhaphy by surgical mesh.Results Postoperatively 127 cases (95%) were followed up from 2 to 18 months with an average of 9. 2months[64 cases of the test group were followed up with an average of(9 ±4) months, 63 cases of the control group followed up with an average of (9 ± 5 ) months]. There was no recurrence. No significant differences were found between the two groups in the operation time (P = 0. 697), blood loss (P = 0. 318 ),hospital stay (P = 0. 116) and total postoperative complications (P = 0. 080). The visual analogue scale of the study group was lower than the scale of the control group ( P = 0. 048 ). Conclusions Modified surgical mesh is more comfortable in the treatment of inguinal hernia with tension-free repair in the preperitoneal space with a comparative result to Rutkow's herniorrhaphy by surgical mesh.
