Objective To compare the clinical effects of three methods in the treatment of osteoarthritis of the knee. Methods Three groups of patients received arthroscopic debridement, sodium hyaluronate injection and combined use of these two methods, respectively. Results All the patients were followed for more than 2 years. According to degrees of joint pain, joint swelling , range of motion and patients’ walking functions, comprehensive scores were obtained. In arthroscopic group, it gave good or excellent results in 86 7% of the patients 6 months ～ 1 year, in 78 8% of the patients 1 year ～ 2 years and 66 2% of the patients after 2 years. In sodium hyaluronate group, the good or excellent rates were 80 6% 6 months ～ 1 year, 72 8% 1 year ～ 2 years and 56 2 % after 2 years, respectively. In combination therapy group, the good or excellent rates were 96 8 % 6 months ～ 1 year, 87 2% 1 year ～ 2 years and 78 1% after 2 years, respectively. Conclusions All the three methods are effective: the combination treatment of arthroscopic debridement and sodium hyaluronate injection is markedly effective, the arthroscopic debridement takes the second place, and the sodium hyaluronate injection is less effective.

Objective:To establish a three-dimensional quantitative structure-activity relationship (3D-QSAR) model for thiazide 11β-hydroxy steroid dehydrogenase ( HSD) inhibitors in order to perform structure modification and find thiazide 11β-HSD inhibitors with more activity. Methods: The 3D-QSAR model of thiazine derivatives was constructed by the method of comparative molecular force field analysis, and the model was validated by using a molecular docking method. Results:An accurate 3D-QSAR model of 11β-HSD inhibitors was obtained (CoMFA:q2 =0. 346, r2 =0. 850, where q2 was the cross-validation coefficient and r2 was the non-cross validation coefficient) . Conclusion:The results provide important theoretical basis for the rational design of novel thiazide 11β-HSD inhibitors.

Objective To analyze the perioperative conditions and long-term survival of patients with non-small cell lung cancer (NSCLC) after thoracoscopic lobectomy. Methods 119 patients with NSCLC underwent thoracoscopic lobectomy from January 2006 to December 2012 were enrolled in the study, then collecting and analyzing their perioperative indicators, pathological results and follow-up data. Results 9 patients converted to thoracotomy with a conversion rate of 7.0 %. The median operation time, the median intraoperative blood loss and off-bed activity time were 170 min (65~440 min), 90 ml (15~3 000 ml) and (32.9 ± 16.3) h after operation respectively. The time and amount of postoperative drainage, the length of hospital stay were (6.7 ± 3.2) d, (1 690.0 ± 410.5) ml, (9.2 ± 4.0) d respectively. The incidence of perioperative mortality and postoperative complications were 0.8 %, 13.4 % respectively. For postoperative pathological type, 96 cases of adenocarcinoma, 19 cases of squamous carcinoma, 2 cases of adenosquamous carcinoma and 2 cases of large cell carcinoma. For discharge patients, the median follow-up time was 34.5 months (0 ~ 102 months). The incidence of local recurrence and distant metastasis in observation group were 5.0 % and 17.6 % respectively. 1-year overall survival (OS) and disease free survival (DFS) were 85.3 % and 79.5 %, 3-year OS and DFS were 69.8 % and 64.8 %, 5-year OS and DFS were 60.8 %and 58.6 % respectively. There was no significant difference in 1-year, 3-year and 5-year OS and DFS between adenocarcinoma and squamous carcinoma (P > 0.05) while there were significant difference in local recurrence and distant metastasis among different stages (P < 0.05). In addition to slightly low OS, DFS of Ⅲ a , Ⅲ b and Ⅳ DFS and OS, the overall living conditions among all stage were similar. Conclusions The long-term survival condition of thoracoscopic lobectomy for NSCLC is ideal, and it’s a safe and effective operation, worthy of clinical promoting.

Objective To systematically review the efficacy and safety of drug-eluting stent(DES) versus coronary artery bypass grafting(CABG) in the treatment of left anterior descending coronary artery(CAD) stenosis.Methods Literature about the efficacy and safety of DES versus CABG for LAD stenosis was retrieved from digital databases of MEDLINE, EMbase, PubMed, and the Cochrane Library by November 2016.Data extraction and quality assessment of included studies were conducted by two independent reviewers.RevMan 5.3 software was used to perform meta-analysis.Results Ten studies involving 9771 patients were finally included.The results of meta-analysis showed that there was no significant difference in mortality [RR=0.88,95%CI(0.70,1.11),P=0.28],major adverse cardiovascular events[MACE,RR=1.04,95%CI(0.88,1.24),P=0.63] or myocardial infarction [MI,RR=0.92,95%CI(0.56,1.53),P=0.75], but PCI-DES significantly increased the risk of TVR [OR=2.43,95%CI(1.61,3.69),P<0.0001].Conclusion For LAD stenosis, PCI-DES strategy causes as high a rate of mortality, MACE and MI as CABG or DES, but PCI-DES can significantly increase the risk of TVR, so we should be cautious clinically.

Objective To investigate the correlation of uric acid(UA) level and the circadian rhythm of blood pressure in hypertensive patients. Methods Among the individuals who presented to the cardiology clinic, 70 patients who had hypertension and were diagnozed with non- dipper hypertension (non-dipper hypertension group) by 24 h ambulatory blood pressure monitoring (ABPM), 70 patients with dipper hypertension patients (dipper hypertension group), and 52 normotensive individuals (control group) were enrolled in this study. Peripheral venous blood samples were collected from all the patients in order to evaluate the hematological and biochemical parameters. All the assessed parameters were compared among three groups. Results The level of UA in non-dipper hypertension group was the highest, in dipper hypertension group was higher and in contrl group was the lowerst:(393.57 ± 53.52), (280.57 ± 41.64), (267.66 ± 59.38) μmol/L, and there were significant differences (P<0.01). Multivariate Logistic regression analysis revealed that the level of UA was an independent risk factor for non-dipper circadian rhythm of blood pressure (P = 0.003, OR = 2.26, 95% CI: 1.34- 3.89). Conclusions The higher level of UA may be a risk factor for non-dipper circadian rhythm of blood pressure in hypertension patients.

OBJECTIVE:To investigate the intervention effects of (E)-4-[2-(4-chlorophenoxy)-2-methylpropanoyloxy]-3-me-thoxyphenyl acrylic acid (AZ) on fat accumulation in human hepatoma HepG2 cells. METHODS:Oleic acid was used to induce fat accumulation in HepG2 cells in logarithmic phase for establishing models of fat accumulation,which were divided into a model group,a positive control group(100 μg/ml simvastatin),and the groups of 15.63,31.25,62.5,125,250,500 and 1 000 μg/ml AZ,and a normal control group was set up. MTT method was used to detect the survival rates of all groups of cells,kit was per-formed to determine the contents of triglyceride (TG) in all groups of cells and calculate the clearance rates,and oil red O stain was conducted to observe the lipid droplet morphology of all groups of cells. RESULTS:Compared to the normal control group, the model group and the groups of 15.63-125 μg/ml AZ demonstrated no obviously different survival rate of cells,and the groups of 250-1 000 μg/ml AZ had lower survival rate of cells. There was statistically significance (P<0.05). The contents of TG in the cells of the model group were higher than those in the cells of the normal control group. The positive control group and the groups of 62.5 and 125 μg/ml AZ had lower contents of TG in the cells compared to the model group,showing a TG clearance rate of (28.58 ± 0.15)%,(14.51 ± 0.09)% and (29.72 ± 0.16)% respectively. There was statistically significance (P<0.01 or P<0.05). There were much more lipid droplets in the cells of the model group than in those of the normal control group. The lipid droplets in AZ groups gradually became less in quantity and smaller with the increasing in drug concentration. CONCLUSIONS:AZ has inter-vention effect on fat accumulation in HepG2 cells.

Objective To investigate the effects of different extracorporeal membrane oxygenation (ECMO) bypass modes on the prognosis of patients with combined pulmonary fibrosis and emphysema (CPFE) during lung transplantation. Methods A retrospective analysis was conducted on 44 CPFE patients who underwent lung transplantation, and they were divided into the venous-venous ECMO (VV-ECMO) group (30 cases) and the venous-arterial ECMO (VA-ECMO) group (14 cases). The preoperative, intraoperative, postoperative and follow-up related indicators of two groups were compared. Results Compared with the VV-ECMO group, the patients in the VA-ECMO group were younger, had higher pulmonary artery pressure before surgery, fewer posterolateral incision types, longer operation times, and higher incidence of postoperative bronchopleural fistula (all P<0.05). The pulmonary artery pressure decreased after surgery in both groups, with a greater decrease in the VA-ECMO group (P<0.05). There was no statistically significant difference in postoperative survival rates between the two groups (P>0.05). Conclusions Both VA-ECMO and VV-ECMO are safe and effective in lung transplant patients with CPFE. The bypass mode has no significant impact on the short and medium-term prognosis of the patients. VA-ECMO is more suitable for patients with higher preoperative pulmonary artery pressure.
