OBJECTIVETo discuss arthroscopic technique of single Kirschner wire and suture avoiding epiphyseal line fixation for tibial intercondylar eminence fracture and its clinical results.

METHODSFrom May 2008 to December 2012, 21 patients (13 males, 8 females, ranging in age from 6 to 14 years old) with tibial intercondylar eminence fracture were treated arthroscopically with single Kirschner wire and suture avoiding epiphyseal line fixation technique. According to Meyers and McKeever classification, 7 patients were type II, 10 patients were type III, and 4 patients were type IV. Active rehabilitation began at one week after operation. The patients were followed up for 10 to 30 months. X-ray films were taken to evaluate fracture healing at 1, 3, 6 months after operation; range of motion, the anterior drawer test, the lachman test and the Lysholm knee score were used to evaluate clinical effects.

RESULTSAll fractures were healed without displacement at 6 weeks after operation. Anterior drawer test and the lachman test were both negative in all patients at 3 months after operation. Lysholm knee score was 95.5 ±2.5 at 6 months after operation, and postoperative X-ray film did not find epiphyseal line broadening or narrowing.

CONCLUSIONArthroscopic treatment for tibial eminence intercondylar fracture with single Kirschner wire and 8-shaped suture avoiding epiphyseal line fixation technique has many advantages, such as firm fixation,early mobilization, less invasive, less injury of physis and satisfactory effect.

There was significant correlation among PCNA, Bcl-2 and TERT protein expression (P≤0.01).· CONCLUSTON: TERT and Bcl-2 take part in the regulation of proliferative cells in epiretinal membrane of traumatic proliferative PVR, with high correlation with the dynamic changes of cell proliferation.

OBJECTIVETo evaluate the efficacy and safety of sertraline and vardenafil in the treatment of patients with concomitant erectile dysfunction (ED) and premature ejaculation (PE).

METHODSSixty patients with concomitant ED and PE received at our clinic of andrology were randomly divided into a vardenafil group and a sertraline group. The vardenafil group received flexible doses of vardenafil from 10 mg to 20 mg and the sertraline group 50 mg daily, both for 2 months. The differences in IIEF-5 before and after the treatment were recorded and compared, and the results of ED treatment evaluated. Intravaginal ejaculatory latency time (IELT) was recorded to evaluate the outcome of PE treatment.

RESULTSIn the vardenafil group, 24 patients had their ED improved and the efficacy rate was 80%, as compared with 27% in the sertraline group. There was significant difference between the two groups (P < 0.05). Twenty patients had their PE improved in vardenafil group, with an efficacy rate of 67% as compared with 40% in the sertraline group. The difference was significant between the two groups (P < 0.05). In both of the two groups, a significantly higher rate of PE improvement was found in patients with improved ED than in those without. Only mild side effects were recorded, and none withdrew from the treatment.

CONCLUSIONTo patients with concomitant ED and PE, the key to the treatment is to improve their erectile function, and for this purpose, vardenafil works better than sertraline.

OBJECTIVETo evaluate the advantages of combination therapy with interferon-alpha plus nucleoside analogue-lamivudine or HBV vaccine in children with HBeAg positive chronic hepatitis B.

METHODSA total of 120 patients with HBeAg positive chronic hepatitis B were divided into three groups, 40 patients per group. Each group was treated with one of the following therapies respectively: Group A IFN-alpha 1b 10 MU/m2 three times per week (Tiw); Group B IFN-alpha 1b 10MU/m2 three times per week (Tiw) plus lamivudine 3 mg/kg for 6 months. Group C IFN-alpha 1b 10 MU/m2 three times per week (Tiw) plus HBV vaccine 30 microg one a month.

RESULTSThere was no significant difference in normalizing rate of ALT among the three groups at end of treatment. There was more significant difference in negative rate (seroconversion) of serum HBV DNA and HBeAg in group B than group A and group C (P less than 0.05).

CONCLUSIONThe combination therapy of IFN-alpha 1b plus lamivudine seemed to be more effective than the therapy with IFN-alpha alone and the combination of IFN-alpha and HBV vaccine.

AIMTo investigate the effects of transforming growth factor-beta1 (TGF-beta1) and signal protein Smad3 on rat myocardial hypertrophy.

METHODSThe total protein was analysed by flow cytometer assay to judge the hypertrophy of myocardial cell incubated with different level of TGF-beta1 in cultured myocardial cells of neonatal rats. The models of rat cardiac hypertrophy were produced with constriction of the abdominal aorta. At the different time after the operation, the rats were killed, and the left ventricular mass indexes (LVMl) were investigated. The mRNA expressions of TGF-beta1 and Smad3 of cultured cells and hypertrophic left ventricles were assessed by RT-PCR, the protein expressions of Smad3 were assessed by Western blot.

RESULTSIn cultured neonatal myocardial cells, different level TGF-beta1 could significantly increase the total protein, and TGF-beta1 (3 ng/ml) could increase the expression of mRNA and protein of Smad3 and continued for 8 h of cultured cardiomyocytes. The LVMI and the expression of TGF-beta1 mRNA and Smad3 mRNA/protein of hypertrophic left ventricle were increased at the 3rd day after the operation and continued for 4 weeks. The peak expression of them was in 2 weeks after operation.

CONCLUSIONTGF-beta1 has the effects on rat myocardial hypertrophy, signal protein Smad3 is included in the pathologic progress of rat myocardial hypertrophy.
