Objective To detect the effect of Danhong injection on cerebral vascular hemodynamic parameters, Cys-c and Hcy in patients with transient cerebral ischemia(TIA), and analyze its clinical effect. Methods 80 TIA patients were selected. The patients were divided into a control group and a Danhong injection observation group with 40 cases each group. The control group was given conventional treatment, and the observation group was given conventional treatment and Danhong injection. The treatment course was 14 d. The hemodynamic parameters, Cys-c and Hcy expresssion were observed. Clinical effect was analyzed. Results After treatment, average blood flow speed (20.07 ± 4.28 cm/s vs. 16.17 ± 2.46 cm/s, t=5.230), average blood flow (11.14 ± 2.24 ml/s vs. 9.54 ± 1.65 ml/s, t=3.637), and cerebral vascular resistance (1 602.4 ± 98.3 kPa/s·m-1 vs. 1 738.5 ± 104.3 kPa/s·m-1, t=6.024) was significantly improved in the observation group than those in the control group (P<0.05). Cys-c (0.48 ± 0.11 mg/L vs. 0.71 ± 0.14 mg/L, t=8.170) and Hcy (17.45 ± 3.26 μmol/L vs. 23.62 ± 4.12 μmol/L, t=7.428) were significantly decreased in the observation group than those in the control group (P<0.05). The recurrence rate of TIA and cerebral infarction were 7.5% and 5% in observation group, which were significantly lower than that of 22.5% and 15% in control group (χ2=2.451, P<0.05;χ2=2.630, P<0.05).Conclusion Danhong injection can reduce the expression of Cys-c and Hcy and recurrence rate of TIA and cerebral infarction.

Objective To observe the long-term effect of surgical treatment in infertile varicocele patients. Methods 180 infertile patients with varicocele accepted modified Palomo operation (retroperitoneal high ligation of internal spermatic cord vein) from 2004 to 2007, and the long-term effect of thesurgery were analyzed retrospectively, such as semen parameters and spouse pregnancy. Results The operations were performed successfully in 180 cases, and semen parameters improved significantly after the surgery (Ps ＜ 0. 05 ).Among all patients, 10 cases had spouse pregnancy within 3 months after operation;47 cases had spouse pregnancy from 3 to 6 months after operation; 25 cases had spouse pregnancy from 6 to 12 months after operation;13 cases had spouse pregnancy from 12 to 24 months after operation. The fertility rate was 52. 8% (95/180) in total. Conclusion Surgical treatment of infertile male patients with varicocele has good long-term effects, made it the first choice in these patients.

Objective To observe the clinical effects of double support plate via posteromedial approach in the treat?ment of tibial plateau fracture of posterior column. Methods A total of 21 cases of tibial plateau fracture in closed posterior column with an average age of 34.6 (range, 21 to 56) years old were treated using double support plate through posteromedial approach from January in 2010 to January in 2013(16 males and 5 females). Among all, 4 cases were combined with lateral column fracture and 17 cases were three column fracture. Wound healings were observed after operation. X-ray examina?tions were performed at 2 weeks, 3 months, 4 months, 6 months and 12 months after operation as well as at last follow up. The averaged healing time was calculated. Changes of tibial plateau angle and posterior slope angle were compared between time points at 2 weeks after operation and at last follow up. Rasmussen knee score criteria was employed to assess knee joint recovery. Results The mean follow-up was (18.2 ± 1.8) months. No infection was reported. The average fracture healing time was 3.8(3.8±0.6)months. There was no significant difference between tibia plateau angle and posterior slope angle be?tween time points at 2 weeks after operation and at last follow-up (P<0.05). According to Rasmussen knee score criteria at last follow-up, 13 cases were graded as excellent, 6 cases as good, and 2 case as fair, with an excellent and good rate of 90.5%. Conclusion With posteromedial approach, the fractures of medial column, posteromedial and posterolateral of pos?terial column can be exposed well. Using double support plates to fix posteromedial and posterolateral of posterior column fracture can effectively prevent loss of reduction and the function of knee recovered well postoperatively.
