Objective To discuss the causes and treatment of angulated healing of long bone shaft fracture at lower limbs. Methods 12 cases of patients with the angulated healing of femoral and tibiofibular fractures were treated surgically in our hospital. In the operation, the plane and angle of the osteotomy were designed according to the specific angulation to restore the normal vertical alignment of the knee joint so that traumatic arthropathy of the knee could be treated or prevented. Results All the patients were followed up for 6 months to 12 years (averaging 66 months). Their lameness was greatly improved, the pain at their knee joints was relieved, and the occurrence or development of the arthropathy were obviously delayed. Conclusions When the angulation of healed long bone shaft fracture at lower limbs exceeds the physical weight bearing line, the condition should be treated surgically. The corrected angulation can delay the occurrence and development of arthritis at the knee. Moreover, corrected angulation and restored alignment is a good method to treat arthropathy of the knee joint.

BACKGROUNDTo study the antibody against hepatitis C virus first envelope (HCV-E1) protein in the sera from patients with HCV and to evaluate the application of HCV-E1 antigen in detection of HCV antibody.
METHODSPurified E1 engineering protein was used as antigen to develop an ELISA for detecting E1 antibody in 80 national reference sera, 821 blood donors' sera and l20 sera from clinical patients with hepatitis.
RESULTSAnti-HCV E1 was positive in 70% (28/40) and negative in 100% (40/40) of 80 national reference sera, and 1.9% (16/821) was positive in blood of the sera donors' and 68% (492/720) positive in sera of patients with hepatitis. Most anti-HCV E1 positive sera were positive for core, NS 3 and NS 5A, but only a few sera were positive for E1 antigen. Of the sera from 218 clinical patients, 813 blood donors and 848 normal people that were anti-HCV negative tested by commercial anti HCV ELISA kit, 1.4%, 1.1% and 0.9% were anti-HCV E1 positive, respectively. Investigation of seroconversion on three patients showed that anti-E1 was first detectable.
CONCLUSIONSDetection of anti-HCV E1 by engineered E1 protein is sensitive and specific. The prevalence and early presence of E1 antibody in HCV infected patients reflect the active status of the disease to a certain extent. Detection of the antibody is useful in clinical diagnosis.

OBJECTIVE:
To determine the effect of trimetazidine on cardiac function and exercise tolerance in primary hypertension patients with type 2 diabetic.
METHODS:
In this randomized, double-blind, placebo-controlled prospective study, 60 primary hypertensive patients with diabetic were equally assigned into two groups, patients received trimetazidine (20 mg, 3 times a day) or placebo for 1 year. Echocardiography, cardiopulmonary exercise testing were performed; and the plasma N terminal pro B type natriuretic peptide (NT-ProBNP), hr-CRP, TNF-α, angiotensin Ⅱ and endothelin concentration were determined before and after treatment.
RESULTS:
In trimetazidine group, the left ventricular mass index, the mitral flow velocity E wave to A wave ratio (E/A), the peak early diastolic velocity (V) to late diastolic velocity (V) ratio (V/V) and the peak systolic velocity (Vs) were significantly improved, the plasma NT-ProBNP level was significantly decreased, and the exercise time, metabolic equivalent, maximal oxygen uptake and anaerobic threshold were significantly increased (all <0.05); plasma concentration of hr-CRP, TNF-α, angiotensin Ⅱ and endothelin were significantly reduced after trimetazidine treatment, compared with baseline (all <0.05) and with placebo (all <0.05). There were no significant differences in any of above parameters after treatment in placebo group (all >0.05). No severe adverse reaction was observed in both groups.
CONCLUSIONS
For patients with both hypertension and diabetes, trimetazidine can improve cardiac function and increase exercise tolerance.

Hangzhou First people's Hospital of Zhejiang University School of Medicine,48 in the Zhangzhou Affiliated Hospital of Fujian Medical University,35 in the Affiliated Quanzhou First Hospital of Fujian Medical University,30 in the Second Affiliated Hospital of Xiamen Medical College.The maximum thickness of subcutaneous fat at the level of umbilicus (USCF),the maximum vertical distance between the anterior abdominal skin and the back skin at the level of the umbilicus (UAPD),the maximum horizontal distance between the anterior abdominal skin and the back skin at the level of the umbilicus (UTD),the maximum verticaldistance between the anterior abdominal skin and the back skin at the level of the xiphoid bone (XAPD),the maximum horizontal distance between the.anterior abdominal skin and the back skin at the level of the xiphoid bone (XTD),the distance between the anterior abdominal skin and the root of celiac artery (CAD) and the maximum horizontal distance at a right angle to CAD (CATD) were measured using preoperative imaging examinations.Observation indicators:(1) intraoperative and postoperative situations;(2) follow-up situations;(3) risk factors analysis of perioperative complications;(4) influence of body shape related indexes on intraoperative situations and postoperative recovery:① Pearson univariate correlation analysis,② liner regression model analysis.Followup using outpatient examination and telephone interview was performed to detect the postoperative survival and tumor recurrence or metastasis up to December 2018.Measurement data with normal distribution were represented as Mean±SD.Measurement data with skewed distribution were described as M (range).Comparisons of count data were analyzed using the chi-square test.Comparisons of ordinal data were analyzed by Mann-Whitney U nonparametric test.Risk factors of perioperative complications of laparoscopic distal gastrectomy were analyzed by Logistic regression model.Influence of body shape related indexes on intraoperative situations and postoperative recovery was analyzed by Pearson univariate correlation analysis and liner regression model.Results (1) Intraoperative and postoperative situations:all the 506 patients underwent successful laparoscopic distal gastrectomy,including 103 with Billroth Ⅰ anastomosis,140 with Billroth Ⅱ anastomosis,201 with Billroth Ⅱ + Braun anastomosis,62 with Roux-en-Y anastomosis.The operation time,volume of intraoperative blood loss,number of lymph nodes dissected,time to postoperative anal exsufflation,time for initial fluid diet intake,time for initial semi-fluid diet intake and duration of postoperative hospital stay were (233±44)minutes,(102±86)mL,34±13,(3.6±1.5)days,(5.8±3.3)days,(8.3±3.8)days,(12.2±5.7)days respectively in the 506 patients.Of 506 patients,196 were defined as pathological stage Ⅰ,122 were defined as pathological stage Ⅱ and 188 were defined as pathological stage Ⅲ postoperatively.Of 506 patients,93 had 106 times of perioperative complications,including 33 times of pulmonary and upper respiratory infection,12 times of incisional infection,11 times of anastomotic leakage,11 times of abdominal infection,8 times of intestinal obstruction,8 times of gastroplegia,6 times of abdominal hemorrhage,5 times of bacteremia,3 times of anastomotic hemorrhage,3 times of lymph fluid leakage,2 times of pancreatic leakage,1 time of urinary infection,1 time of anatomotic stenosis,1 time of deep venous thrombosis and 1 time of pulmonary embolism;the same patient can merge multiple complications.Eleven patients were in the Clavien-Dindo classification ≥ Ⅲ.(2) Follow-up situations:465 of 506 patients were followed up for 1-32 months with a median time of 12 months.During the follow-up,451 had postoperative survival and 38 had tumor recurrence or metastasis.(3) Risk factors analysis of perioperative complications.① Results of univariate analysis showed that age,body mass index (BMI),preoperative hemoglobin,preoperative serum albumin and XAPD were related factors affecting perioperative complications of laparoscopic distal gastrectomy (x2 =10.289,7.427,5.269,5.481,4.285,P< 0.05).② Results of multivariate analysis showed that age,BMI,preoperative serum albumin were independent related factors affecting perioperative complications of laparoscopic distal gastrectomy (odds ratio =1.033,1.118,0.937,95% interval confidence:1.011-1.057,1.025-1.219,0.887-0.990,P<0.05).(4) Influence of body shape related indexes on intraoperative situations and postoperative recovery.① Results of Pearson univariate correlation analysis showed correlations between UAPD,XAPD,CAD,CATD and volume of intraoperative blood loss (r=0.107,0.169,0.179,0.106,P<0.05),between UAPD,XAPD,CAD and the number of lymph nodes dissected (r=-0.137,-0.143,-0.173,P<0.05),between USCF,XAPD and time to postoperative anal exsufflation (r =0.122,0.109,P<0.05),between USCF,XAPD,CAD and time for initial fluid diet intake (r=0.132,0.108,0.132,P<0.05),between USCF,XAPD and duration of postoperative hospital stay (r=0.116,0.100,P<0.05).② Results of liner regression model analysis showed a positive correlation between CAD and volume of intraoperative blood loss (r =6.776),a negative correlation between CAD and the number of lymph nodes dissected (r =-0.841),with statistically significant differences (t =2.410,-1.992,P< 0.05);a positive correlation between USCF and time to postoperative anal exsufflation (r=0.170),between USCF and time for initial fluid diet intake (r=0.365),between USCF and duration of postoperative hospital stay (r=0.636) respectively,with statisticallysignificant differences (t =2.188,1.981,2.107,P< 0.05).Conclusions Abdominal shape can influence intraoperative situations and postoperative recovery of laparoscopic distal gastrectomy,but cannot increase risks ofperioperative complications.Age,BMI and preoperative serum albumin are independent related factors affecting perioperative complications of laparoscopic distal gastrectomy.
