To introduce the methods and experience of arthroscopy treating different types of sports traumatic ankle arthritis.Methods The study involved 25 patents with spots traumatic ankle arthritis treated under ankle arthroscopy from January 2008 to October 2010.American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot scoring system was applied to make functional evaluation before and after operation.Also,anterior drawer stress radiographs were used to assess the stability of joint.All patients had arthroscopic examination and received corresponding treatments,including synovial scar tissue resection,cartilage surface trimming,and microfracture management.Five patients underwent stage Ⅰ extramalleolus ligament repair.Results Arthroscopy showed simple synovitis in four patients,impingement syndrome developed from synovitis with fibrous scar tissue formation in 10,tibial or talus cartilage lesions in 11 and congestion of fresh injury of fibular end in four.A total of 23 cases were followed up for average 13.5 months (range,6-24 months).The ankle-hindfoot score was increased from preoperative (54.3 ± 6.2) points to (81.5 ± 7.9) points at 1 month,(82.9 ± 2.5) points at 3 months,( 83.1 + 2.1 ) points at 6 months and ( 83.5 ± 3.9 ) points at 12 months,with statistical differences ( t =13.01,20.58,21.10,19.11 respectively,P＜0.05).The anterior drawer stress radiographs showed that the anterior translation of talus improved from preoperative ( 15.2 ± 2.5 ) mm to postoperative (3.5 ± 0.2 ) mm,with statistical difference ( t =9.33,P ＜ 0.05 ).The anterior drawer test and talus tilt test were both negative for all patients.Concluslons Ankle arthroscopy is characterized by micro trauma and fast recovery.Symptomatic treatment under arthroscopy can obviously relieve the uncomfortable symptoms following sports traumatic ankle arthritis.

Objective To evaluate the effects of known-to-have health management on diabetes patients.Methods A total of 585 diabetic patients from Desheng Community of Beijing received an intensive health management for 3 months,including diet intervention,physical exercises,medication,health education and individual health guidance.Body weight (BW),body mass index (BMI),waist circumference (WC),blood pressure (BP),fasting blood glucose (FBG),2-h postprandial blood glucose (PBG),glycated hemoglobin A1C (HbA1 c),total cholesterol (TC),triglycerides (TG),high-density lipoprotein cholesterol (HDL-C),low-density lipoprotein cholesterol (LDL-C),total physical exercises,effective physical exercises,effective physical exercise ratio to BW and dietary intake were compared before and after the intervention.Results Of 585 patients with type 2 diabetes mellitus,240 were male and 345 were female (average age (64.4 ± 9.1) years old).BW,BMI,WC,systolic blood pressure,diastolic blood pressure,FBG,2-h PBG,HbA1c,TC,TG,HDL-C,LDL-C,amount and time or frequency of effective physical exercises,effective physical exercise ratio to BW and total dietary intake were significantly improved after intensive health management (t values were 20.35,20.34,23.74,14.06,12.35,13.35,16.50,9.90,7.53,6.37,-3.74,4.91,-7.44,-7.91,-5.60,-8.41 and 5.21,respectively ; all P ＜ 0.05).More healthy eating habits were found in 321 subjects (54.8％).Those having normal FBG were increased from 54.2％ to 80.1％ following known-to-have health management,with 2-h PBG from 60.4％ to 87.8％ and HbA1c from 58.9％ to 77.9％ (x2 values were 88.21,109.31 and 39.97,respectively; all P ＜ 0.05).Conclusion Known-to-have management may provide an effective tool for community diabetics.

Objective To investigate the correlation of microperimetric parameters,best-corrected visual acuity (BCVA) and central retinal thickness (CRT) in diabetic macular edema (DME) eyes.Methods It is a prospective,no controlled,open study.Twenty-four consecutive patients (40 eyes) with DME were included.There were 10 males (18 eyes),14 females (22 eyes);aged from 41 to 79 years,with the mean age of (56.84±8.96) years.All the patients were type 2 diabetes,the average duration of diabetes was 8 years.BCVA was evaluated using the international Snellen E vision test chart,and then recorded as logarithm of the minimum angle of resolution (logMAR).CRT was measured by Cirrus HD-OCT4000.MAIA microperimetric parameters were evaluated,including average threshold (AT) of retinal sensitivity,macular integrity index (MI),fixating points within a circle of 1° (P1) and 2° of radius (P2),bivariate contour ellipse area (BCEA) considering 63％ and 95％ of fixating points (A63,A95),and horizontal and vertical axes of that ellipse (H63,H95,V63,V95).Pearson correlation analysis was performed to evaluate the association between these variables.The independent factor influenced the type of fixation was analyzed by multiple linear regression analysis.Results Strong correlations of logMAR BCVA with CRT (r=0.58,P=0.000),V63 (r=0.44,P=0.004),V95 (r=0.41,P=0.008),MI (r=0.36,P=0.024),AT (r=-0.61,P=0.000),P1 (r=-0.41,P=0.009),P2 (r=-0.38,P=0.015) were found.AT was correlations with P1 (r=0.53,P=0.000),P2 (r=0.51,P=0.001),A63 (r=-0.39,P=0.012),A95 (r=-0.40,P=0.012),V63 (r=-0.53,P=0.000),V95 (r=-0.46,P=0.003),MI (r=-0.50,P=0.001).There was no correlation between AT and CRT (r=-0.21,P=0.190).Forty eyes were included in this study,8 eyes (20％) had stable fixation,14 eyes (35％) had relatively unstable fixation,18 eyes (45％)had unstable fixation.Multiple linear regression analysis showed that fixation classification was independently affected by P 1.Conclusions In DME eyes,logMAR BCVA was positively correlated with CRT,negatively correlated with AT,P1 and P2.There is no correlation between AT and CRT.The fixation classification was independently affected by P 1.

Objective To establish a sandwich ELISA for early detection of HIV antigens using a mixture of monoclonal antibodies (McAb). Methods The ascites McAbs (anti-HIV-1 p24, anti-HIV-1 gp41, anti-HIV-1 gp120 and anti-HIV-2 gp36) were purified by the SAS and the affinity chromatography,and then were labeled with HRP by sodium metaperiodate. The establishing of sandwich ELISA for detecting the single HIV antigen and the tests of specificity and sensitivity of these systems were performed in advance.A proper ratio mixture of four screened McAbs was used as the capture antibody and a proper ratio mixture of four labeled antibodies was used as the detecting antibody. The method of using sandwich ELISA to detect HIV antigens was set up with these McAbs. Results The sensitivity of this method detecting HIV antigens are:0.625 pg/ml HIV-1 p24, 6.25 ng/ml HIV-I gp41,6.25 ng/ml HIV-I gp120 and 9.25 ng/mi HIV-2 gp36 in mixed HIV antigens. Conclusion The method of using several McAbs mixture in sandwich ELISA detecting HIV antigens was established an excellent sensitivity, which provides a novel idea for early detec-ting the HIV antigen.

Objective To investigate the clinical efficacy of precise liver resection of liver tumors adjacent to the main pipeline.Methods The retrospective and descriptive study was conducted.The clinical data of 22 patients who underwent precise resection of liver tumors adjacent to the main pipeline in the Affiliated Tumor Hospital of Zhengzhou University between December 2014 and June 2016 were collected.According to preoperative precise evaluation and fully intraoperative exposed tumors,different methods of blood flow occlusion were choosed timely,and then precise resection of the liver was evaluated based on tumor location and size,relationship between tumor and blood vessels and the degree of liver cirrhosis.The operation procedures,operation time,time of liver resection,volume of intraoperative blood loss,number of patients with perioperative blood transfusion,postoperative complications,duration of postoperative hospital stay and follow-up were observed.The follow-up was performed by outpatient examination and telephone interview up to September 2016.Tumor recurrence of patients with hepatocellular carcinoma (HCC) was monthly detected by alpha-fetoprotein retest and color Doppler ultrasound of the liver or computed tomography (CT) within 3 months postoperatively.Tumor recurrence of patients with cholangiocarcinoma was monthly detected by tumor marker retests,color Doppler ultrasound of the liver or CT,and then patients without tumor recurrence received reexamination once every 2 months after 3 months.Patients with liver hemangioma were followed up once every 2-3 months and once every 6 months after half a year,and follow-up included the liver function,ultrasound and other imaging examinations to detect the tumor recurrence.Measurement data with normal distribution were represented as-x±s.Results All the 22 patients underwent successful precise resection of liver tumors.Twenty patients received intraoperative ultrasound localization.Blood flow occlusion of 22 patients:Pringle was conducted in 6 patients,treatment of the corresponding hepatic pedicle in 3 patients,selective hepatic blood flow occlusion in 8 patients,total hepatic blood flow occlusion in 2 patients and non-hepatic portal occlusion in 3 patients.Precise resection of the liver of 22 patients:1 patient underwent right trisegrnentectomy,2 underwent left hepatectomy,2 underwent segment Ⅳ a resection of the liver,2 underwent segment Ⅳ resection of the liver,3 underwent segment Ⅴ resection of the liver,3 underwent segment Ⅷ resection of the liver,1 underwent middle lobe resection of the liver and 8 underwent partial resection of the liver.Operation time,time of liver resection,volume of intraoperative blood loss and number of patients with perioperative blood transfusion were (213±39) minutes,(57± 19) minutes,(518± 98) mL and 3,respectively.Of 22 patients,5 with postoperative complications were improved after symptomatic treatment,including 2 with effusion at surgical site,2 with right pleural effusion and 1 with bile leakage.The duration of postoperative hospital stay of 22 patients was (8.9± 1.6)days.Twenty-one patients were followed up for 3-20 months,with a median time of 12 months.Two of 22 patients had recurrence during the follow-up,and no recurrence at surgical site was detected.Conclusion Precise resection of liver tumors adjacent to the first and second hepatic hilum is safe and feasible,with the advantages of less intraoperative bleeding and low incidence of postoperative complications.

Objective:To study the regulatory effects of Ligustrazine Hydrochloride(LHC)on tumor-induced immunosuppression by Colon26 cells in vitro.Methods:Colon26 cells were cultured for 48 h in the presense of LHC and either the cell fraction or the cultural supernatants was collected,with the untreated Colon26 cells as control for the study.The down-regulating effects of LHC on tumor immunosuppressions (including the suppressed NK killing and ConA induced transformation of murine spleen cells detected by MTT,and the reduced expression levels of IL-2R?,CD3?+?+ and CD3?-?+ detected by FCM) were determined.The concentrations of immunosuppressive cytokines,including TGF-?1,VEGF,IL-4,IL-6 and IL-10,in the supernatants were analyzed by quantitative ELISA.The relationship among the down-regulatory effects of LHC on secretion immunosuppressive cytokines and tumor immunosuppressions were evaluated by multiple linear regression analysis.Results:All of the cytokines assayed were found in the supernatant of Colon26 treated without LHC,in which TGF-?1 was the highest,and the significant inhibition of five immune functions mentioned above was showed.To the Colon26 treated by LHC,the concentrations of TGF-?1,IL-6 and IL-10 in the first re-cultured supernatant and its inhibition of five immunol functions decreased greatly.The concentrations of TGF-?1 and IL-6 in the second re-cultured supernatant and its inhibitions of transformation,CD3+?+ and CD3-?+resumed highly.The positive correlations existed between TGF-?1 and inhibition of immunol functions except for transformation,between IL-6 and inhibition of transformation or CD3-?+,between IL-10 and inhibition of NK killing or IL-2R? or CD3+?+,respectively.Conclusion:LHC can exert down-regulate effects on Colon26 secretion of immunosuppressors and its tumor immunosuppression.Reducing tumor immunosuppression of Colon26 through decreasing its secretion of immunosuppressors should be one of anti-tumor mechanisms of LHC.

Objective To investigate the clinical feasibility of contrast?enhanced three dimensional T2WI turbo?spin?echo sequence with short?term inversion recovery and sampling perfection using different flip angle evolutions (3D STIR T2WI SPACE) sequence in the brachial plexus neurography. Methods Thirty two patients were prospectively chosen and performed with brachial plexus plain scanning on a 3.0 T MR scanner by using plain and contrast?enhanced 3D STIR T2WI SPACE sequence. Thirteen of them underwent plain scan, 9 of them underwent contrast?enhanced scan, and 10 of them underwent both plain scan and enhanced scan. The visibility of the brachial plexus were scored and contrast to noise ratio (CNR) were measured by two experienced radiologists. The results between plain and contrast?enhanced imaging were compared by t test. The 10 subjects received both enhance and plain imaging, were performed with paired t test. Results In 32 patients, the visibility score of brachial plexus nerve and CNR were 7.8 ± 1.3 and 24.97±3.41 in the plain scan group, and 13.1±1.7 and 38.49±4.95 in enhanced scan group, respectively. There were statistically significant differences in the two groups(t=-11.72,P<0.01;t=-10.47, P<0.01). In 10 cases with plain and enhanced brachial plexus imaging, the average score of the brachial plexus were 7.4 ± 1.7 and 13.3 ± 1.6, the average CNR were 26.23 ± 4.43 and 38.19 ± 5.03 respectively. There were statistically significant differences (t=- 8.22, P<0.01; t=- 5.64,P<0.01). The score results were analyzed for consistency. Plain images Kappa value was 0.684, which shows moderate consistency and enhanced images Kappa value= 0.822, which shows excelent consistency. Conclusions The contrast?enhanced 3D STIR T2WI SPACE sequences may suppress background tissue signals, which is helpful to display brachial plexus, therefore it is of important value for the early diagnosis of brachial plexus neuropathy.
