Objective To determine the risk factors related to venous thromboembolism after knee arthroscopy. Methods A retrospective study including patients from Feb 2012 to Mar 2016 was carried out to analyze the risk factors of venous thromboembolism after knee arthroscopy. A 1 : 2 matched control group was generated according to the surgeon and the date. Preoperative and perioperative data were collected with respect to age, gender, body mass index, smoking, blood fat, surgical procedure, the time length of ligating tourniquet, anesthesia methods, surgery time and Caprini evaluation. Univariate and multivariate analyses were performed. Results 29 cases of venous thromboembolic events (VTEs) occurred, resulting in an incidence rate of 1.17%. Factors associated with an elevated risk of postoperative VTEs included age OR^ =1.09, 95%CI (1.03, 1.16) and Caprini evaluation OR^ =2.97, 95% CI (1.39, 6.32). Conclusions In this study, VTEs occurred infrequently. Considering the serious result of VTEs, it is important to prevent it. Age and Caprini are associated with elevated risk of postoperative VTEs. It is essential to target those at high risk for VTEs and appropriately treat those patients.

Objective To investigate the protective effects of extract of Xihuangcao Tea on chemical hepatic injury in mice and rats.Methods Mouse models of chemical hepatic injury were induced by CCl4 and rat models of jaundice by ?-naphthylisothiocyanate(ANIT).Then extract of Xihuangcao Tea was administered and enzyme activity of SGPT in the serum was measured in the mice.The serum level of total billirubin was determined in the rat jaundice models.Results Compared with the models,the enzyme activity of SGPT was significantly reduced and serum total bilirubin level decreased in extract of Xihuangcao tea groups(P

There exist a number of mercury-resistant bacterial in environment, Mer operon is involved in the resistant mechanism, MerRTPA of Mer operon encodes the proteins related to the regulation, transport and reduction of mercury ion, respectively. The toxic mercury ion is transported by MerTP from medium to cytoplasmic mercuric reductase, MerA, and deoxidized to non-toxic and volatile element mercury, Hg(0). Bacterial mercury-resistant system originated from ancient times, and evolved into the Mer operon with diversity by gene integration and insertion. Mercury-resistant bacteria highly specifically absorb mercury ion, and can be used in recovering the mercury-polluted environment as well as the genetic selective marker.

Objective To compare the efficacy and complications between an auto negative pressure generation biopsy device and Bard biopsy device in renal biopsy in the elderly.Methods A total of 282 patients in our department received renal biopsies with auto negative pressure generation biopsy device (n=159) versus Bard device (n=123).The quality of tissue biopsy specimen and postoperative complications were analyzed retrospectively.Results There were no significant differences in the success rate,incidences of perirenal hematoma and gross hematuria between the two groups (96.9％ vs.95.1％,29.6％ vs.30.1％,1.9％ vs.1.6％,P＞0.05).While the average number of glomeruli,the average length and width of kidney tissue specimen were much more,longer or wider by the auto negative pressure generation renal biopsy device than by the Bard device [(17.9± 11.5) vs.(12.6±9.9),(11.5±5.0)mm vs.(7.8±3.0) mm,(1.0±0.2) mm vs.(0.8±0.4) mm,respectively,all P＜0.05].Conclusions There are no significant differences in the success rate and postoperative complications between auto-negative pressure generation renal biopsy device and Bard device.The auto negative pressure generation renal biopsy device has the advantage in obtaining more renal tissue,with the same effectiveness and safety as the Bard device.

Objective To investigate the surgical curative effect of long-segment fixation and fusion on the degenerative scoliosis (DS) in the elderly.Methods The clinical data of 27 patients with DS undergoing surgical treatment from January 2011 to December 2013 in our department in Beijing Hospital were retrospectively analyzed.All patients suffered from degenerative scoliosis accompanied with lumbar canal stenosis, lumbar spondylolisthesis, lumbar vertebrae lateral slip in coronal surface, spinal vertebral rotation deformity and kyphosis.The decompression osteotomy and fixed segment, blood loss volume and operation time were recorded.The differences in scoliosis angle (Cobb angle), lumbar lordotic angle, top vertebral rotation degree (Nash-Moe vertebral rotation grade), apical vertebral offset distance, visual analogue scale (VAS) score and Oswestry disability index (ODI) score were compared between pretreatment versus the last follow-up.Results The selective 1-5 segment decompression and 5-10 segment fusion were selected in a total of 27 patients.Some patients were treated with Smith-Petersen osteotomy (SPO).All of 27 cases were treated with a lamina and inter-transverse fusion, among which 25 cases took inter-vertebral fusion additionally.The time of postoperative follow-up was more than 1 year.The Cobb angle, lumbar lordotic angle, apical vertebral offset distance, VAS and ODI scores were improved after treatment as compared with pretreatment [(11 6) vs.35 6 , (32±10) vs.(17±9) , (16.3±8.2) mm vs.(32.2±9.8) mm, (3.3±1.6) vs.(7.3±2.1), (18±14) vs.(33±14), t=2.469, 2.313, 2.331, 2.362, 2.395, P=0.021, 0.030, 0.029, 0.026, 0.023 respectively].The satisfaction survey result was excellent in 19cases, good in 5 cases, fair in 3 cases.Complications were found in 9 patients, among whom 2 cases had screw loosening in the internal fixation, 2 cases had adjacent segment degeneration, 1 case had pulmonary infection, 1 case had urinary tract infection, 2 eases had spinal fluid leakage, 1 case had epidural hematoma.No serious complications and deaths were observed.Conclusions Under strictly controlling the therapeutic indications, the limited decompression and long-segmental fixation and fusion have good therapeutic efficacy on degenerative scoliosis in elderly patients.
