OBJECTIVETo investigate the clinical effects of enblock distal radius T-plate fixation in treating trailing edge fracture of tibial plateau medial condyle and posterior cruciate ligament (PCL) avulsion fracture.
METHODSFrom September 2008 to November 2011, 5 patients with trailing edge fracture of tibial plateau medial condyle and PCL avulsion fracture caused by knee joint hyperextension,were treated with surgery. There were 3 males and 2 females with an average age of 35 years old (25 to 42). Left knee injury was in 3 cases and right knee had in 2 cases; 2 cases caused by sports injury and 3 cases caused by road accident. All patients were undergone emergency treatment. Fractures were anatomically reduced and fixed with T-plate through poples approach. Complications were observed after operation. Bone healing and clinical effects were respectively evaluated by X-rays and HSS system.
RESULTSFive patients were followed up for 1 to 4 years with a mean of 2 years. All incisions obtained healing of I stage. All knee joints recovered well and were stable with inflexion more than 120 degrees, no complications such as knee joint pain, injuries of nerve and blood vessel, infection, internal fixation failure were found. The mean score of HSS system was 94.40 +/- 6.09 and all patients got excellent result.
CONCLUSIONFor the treatment of trailing edge fracture of tibial plateau medial condyle and PCL avulsion fracture caused by knee joint hyperextension, enblock distal radius T-plate fixation had advantages of good stability,higher success rate, and knee joint function can recover well.

OBJECTIVETo observe the therapeutic effects of steel plate fixation after the failure of arthrodesis of ankle by screw fixation.
METHODSFrom August 2001 to October 2011, 15 patients were with steel plate fixation after failure of arthrodesis of ankle by screw fixation. Among patients, 9 cases were males and 6 cases were females,ranging age from 40 to 65 years old with the average of 56 years old. Ten cases were in left and 5 cases were in right. Screws were removed and steel plate was fixed intraoperatively, and plaster external fixation for postoperation. Clincal effect were evaluated according to AOFAS scoring system from pain, waliking ability and aligment before and after operation, and X-ray was used to evaluate joint fusion after operation.
RESULTSAll patients were followed up, and the duration ranged from 4 months to 4 years with an average of 2 years. The incison were healed in stage I. No ankle pain,injury of blood vessel and nerve,infection and farilure of internal fixation occuerred. The AOFAS score increased from 36.86 +/- 8.32 preoperatively to 85.09 +/- 4.65 (t = -26.366, P = 0.000).
CONCLUSIONSteel plate fixation after the failure of ankle arthrodesis of screw fixation has the advantages of rigid stability, simple manipulation and high success rate, less pain, perfect recovery.

Influenza virus causes serious threat to human life and health. Due to the inherent high variability of influenza virus, clinically resistant mutant strains of currently approved anti-influenza virus drugs have emerged. Therefore, it is urgent to develop antiviral drugs with new targets or mechanisms of action. RNA-dependent RNA polymerase is directly responsible for viral RNA transcription and replication, and plays key roles in the viral life cycle, which is considered an important target of anti-influenza drug design. From the point of view of medicinal chemistry, this review summarizes current advances in diverse small-molecule inhibitors targeting influenza virus RNA-dependent RNA polymerase, hoping to provide valuable reference for development of novel antiviral drugs.

OBJECTIVEThrough an analysis of the effect of PKP (percutaneous kyphosis plasty) for aged osteoporotic spinal multiple fracture to demonstrate the importance of the selection of responsible veterbal body.
METHODSTwenty-four consecutive procedures were performed in 19 aged patients with osteoporotic spinal compression fractures from May 2004 to October 2007. The 24 responsible veterbal bodies were confirmed by the manifestations of MRI, X-ray, physical examination before the procedures. Established work path through hibateral vertebral arch, put into saccule, poured in bone cement under X-ray perspective. To observe the condition about symptom improving, fractured reduction and complications after operation.
RESULTSThe operations were successfully completed and the pain released obviously at 2 days after operation. The patients can walk next day after operation and no complication found. The mean loss percent of the anterior and middle vertebal heights were respectively (34.22 +/- 11.51)% and (26.53 +/- 11.61)% before operation,postoperative were respectively (13.21 +/- 11.43)% and (15.10 +/- 6.50)%. The mean kyphosis corrected from (24.50 +/- 3.10) degrees to (8.70 +/- 4.30) degrees; the VAS scores decreased from 83.00 +/- 6.00 to 27.00 +/- 5.00. There was significant difference between before and after operation (P < 0.01).
CONCLUSIONSPKP for aged osteoporotic spinal multiple fractures by selecting true veterbal body has satisfactory clinical efficacy. We should emphasize the importance of the selectivity of responsible veterbal body in the procedures. It needs three essential elements: (1) Obviously spinous process tenderness and rap pain. (2) X-rays showed veterbal body compression fracture; MR showed low signal in veterbal body by T1WI, and high signal by T2WI, STIR. (3) The manifestation of radiology can be explained clearly by clinical symptomes arid signs.

OBJECTIVETo investigate the epidemiological changes of erectile dysfunction (ED) patients in the past five years.
METHODSIn 2003 and 2008, we conducted two questionnaire investigations on the epidemiological changes of ED outpatients in 11 Chinese cities in such aspects as age, disease course, ED severity, smoking and drinking habits, accompanying hypertension, diabetes and coronary heart disease (CHD), and sexual intercourse satisfaction.
RESULTSAccording to the valid copies of the questionnaire collected (808 in 2003 and 858 in 2008), the age pattern of the ED patients hardly changed in the past five years, over 60% aged 30 - 50 years. Compared with the results obtained in 2003, the second investigation showed obvious increases in the following numbers of the ED patients: by 13% in those with longer disease courses (5 - 10 yr), from 24.1 to 42.9% in those with moderate ED, from 20.4 to 29.9% in those with severe ED, by at least 10% in those with smoking and drinking habits, from 11.5 to 16.2% in those with hypertension, from 9.4 to 13.5% in those with diabetes, and from 57.6 to 73.3% in those without sexual satisfaction, while the number of those with CHD did not change significantly.
CONCLUSIONIncreased unhealthy living habits and erectile function impairing diseases have added to the incidence and severity of ED. There is still much work to be done in the prevention and early treatment of ED.

The most appropriate time to introduce androgen deprivation therapy for prostate cancer remains controversial. Our aim was to evaluate the effects of early versus delayed surgical castration on prostate cancer progression and survival in the transgenic adenocarcinoma of the mouse prostate (TRAMP) model. TRAMP mice were randomly divided into three groups: the early castration group (on which castration was performed at the age of 4 weeks), the delayed castration group (on which castration was performed when abdominal tumours could be palpated), and the sham-castrated group. Mice were monitored daily throughout their lives until cancer-related death or the development of an obviously moribund appearance, at which time the individual mouse was killed. Androgen receptor expression in prostate tumours was also evaluated. The results shows that the average lifespan in early castration, delayed castration and sham-castrated groups were 54.1 weeks, 59.9 weeks and 39.1 weeks, respectively. Both early castration and delayed castration conferred a statistically significant survival advantage when compared with the sham-castrated group (P<0.001). However, the difference in lifespan between the early castration group and the delayed castration group was not statistically significant (P=0.85). The increase in lifespan in the TRAMP mice that received either early or delayed castration correlated with lower G/B value (genitourinary tract weight/body weight) at death than the sham-castrated mice. In conclusion, early and delayed castrations in TRAMP mice prolonged survival to a similar extent. This finding may provide a guide for clinical practice in prostate cancer therapy.

To evaluate the clinical outcomes of loupe-assisted intussusception vasoepididymostomy (VE) in the treatment of epididymal obstructive azoospermia (EOA), we retrospectively analyzed data from 49 patients with EOA who underwent two-suture longitudinal intussusception vasoepididymostomy (LIVE) between 2000 and 2007. The data included the surgical method, postoperative motile sperm count per ejaculation, percentage of progressive motile sperm and patency and pregnancy outcomes. There were a total of 49 men undergoing scrotal exploration, and epididymal obstruction was found in all cases. Bilateral or unilateral anastomoses were performed in 40 and 6 men, respectively. The postoperative courses of 42 patients were followed up for more than 6 months, and the courses of 38 patients were followed up for more than 1 year. The overall patency and pregnancy rates were 71.4% and 26.3%, respectively. Moreover, progressive motile sperm was more frequently present in those patients who had undergone anastomosis at cauda than at corpus or caput. Pregnancy was achieved only in those patients who had undergone anastomosis at least on one side of the cauda epididymis. We think that the loupe-assisted method, with a lower overall cost and a simplified surgical procedure, can achieve satisfactory patency outcomes and pregnancy results. Data from this paper also suggest that paternity outcomes occur more frequently after anastomoses at cauda than at corpus or caput.
