OBJECTIVE: To establish the quality stangard of Erkening misture.METHODS:Raphanus sativus and Fritillaria thunbergii were identifided by TLC, and the content of the Baicalin in Erkening misture was determinated by HPLC. RESULTS: The TLC spots of Raphanus sativus and Fritillaria thunbergii were distinctive. The linear range of Baicalin was 0.319～2.64 ?g (r=0.999 3). The average recovery was 99.56%, and RSD was 0.83% (n=9). CONCLUSION: This established standard can be used for the quality control of the Erkening misture.

BACKGROUND:Both local infiltration analgesia and femoral nerve block are used for the pain management after total knee arthroplasty. Controversy stil remains regarding the optimal technique for pain relief. OBJECTIVE:To systematical y evaluate analgesic effects of local infiltration analgesia and femoral nerve block after total knee arthroplasty. METHODS:Databases including PubMed, EMBASE, the Cochrane Library, Web of Science and CBM, were comprehensively searched to identify randomized control ed studies comparing local infiltration analgesia with femoral nerve block. Two reviewers independently selected trials, included literatures, extracted data, and assessed the methodological qualities of included studies according to Cochrane Handbook for Systematic Reviews of Interventions Version 5.1.0. When there were different opinions, it was decided by the third author. Data were analyzed by RevMan 5.3 software. RESULTS AND CONCLUSION:(1) Eleven randomized control ed trials involving 566 patients were included. (2) At 24 and 48 hours (h) after surgery, there were no significant differences between the local infiltration analgesia and femoral nerve block groups, in Visual Analog Scale scores [MD24 h=0.15, 95%CI (-0.26, 1.28), P>0.05;MD48 h=0.19, 95%CI (-0.06, 0.44), P>0.05] in the resting state, and [MD24 h=-0.01, 95%CI (-0.51, 0.48), P>0.05;MD48h=0.18, 95%CI (-0.45, 0.82), P>0.05] in the active state, amount of analgesic drug use [MD24 h=-2.23, 95%CI (-5.63, 1.16), P>0.05;MD48 h=2.44, 95%CI (-1.08, 5.95), P>0.05], hospital stay [MD=0.05, 95%CI (-0.40, 0.50), P>0.05], postoperative nausea and vomiting [OR=1.09, 95%CI (0.39, 3.04), P>0.05] and postoperative infection [OR=0.99, 95%CI (0.44, 2.59), P>0.05]. (3) These results indicated that the analgesic effect of local infiltration analgesia was identical to that of femoral nerve block after total knee arthroplasty. Due to its simple operation, local infiltration analgesia can be used as a standard analgesia method after total knee arthroplasty.

Three children were followed up for 1 month,7 months and 1 year respectively with disease controlled and a child was withdrawn treatment from.

Objective To study the clinical characterics of 139 patients with wide QRS complex tachycardia.Methods Retrospective analysis was performed on 139 patients with QRS wave tachycardia treated by radiofrequency ablation at TEDA International Cardiovascular Hospital.The patients were divided into supra-ventricular tachycardia with intra-ventricular aberrany group (group A,n =84) and ventricular tachycardia (group B,n =55).The clinical data,electrocardiogram (ECG) and echocardiographic features between the two groups were compared.Results There was no statistical significance between the two groups in terms of gender,height,weight and ventricular rate (P ＞ 0.05).The difference in the course of disease,blood pressure,age,QRS duration,left ventricular diameter by echocardiography and ejection fraction was statistically significant (P ＜ 0.05).Radiofrequency ablation result showed that 81 (96.4％) cases were successful in group A,and 37 (67.3％) cases were successful in group B.The difference in the success rate was statistically significant (P ＜0.05).After 1 year of follow-up,4 (2.9％) cases in group A were recurred,13 (23.6％) cases in group B were recurred.The difference in the recurrence rate was statistically significant.Conclusion The wide QRS wave tachycardia is often accompanied with left ventricular diameter enlargement and left ventricular ejection fraction reduction,The success rate of radiofrequency ablation is low,and the recurrence rate is high when diagnosis is ventricular tachycardia.

Objective To investigate the clinical effect of the treatment for hand trauma with free flap of radial artery superficial palmar branch.Methods Selected 100 cases of patients with hand trauma who were treated in our hospital from January 2013 to December 2015.All the patients were treated with free flap of radial artery superficial palmar branch.The postoperative necrosis rate,survival rate,and infection rate of flap of all the patients were observed.All the patients were followed up for 6 months,and the healing of fracture were evaluated by X-ray examination so as to evaluate the hand function recovery.Results After the treatment,there were 9 cases of flap local necrosis and 10 cases of local infection,and the necrosis rate and infection rate were 9% and 10% respectively.The infection was controlled effectively after the symptomatic treatment and the flaps all survived.The swelling degree of skin flap was slight and the appearance was good.After 6 months of follow-up, the 100 cases all get epithelization completely.The X-ray examination showed that the fracture healing is good,with 7 cases of hook nail deformity and 5 cases of slow nail regeneration.The hand function recovery was excellent in 73 cases (73%),good in 16 cases (16%),and medium in 10 cases (10%).Conclusion It is an effective treatment for hand trauma with free flap of radial artery superficial palmar branch,as it can receive high flap survival rate and good recovery of hand function.

Objective:To analyze and investigate the clinical efficacy on repairing soft tissue defects of the thumb distal with dorsal neurocutaneous vascular flap.Methods:Select 100 cases of patients with soft tissue defects of the thumb distal from January 2014 to December 2016,who were randomly divided into two groups,the control group and observation group.Take the abdominal skin flap to repair soft tissue defects of the thumb distal in the control group,with the thumb distal with dorsal neurocutaneous vascular flap in the observation group.The survival condition,the indicators of feelings,the appearance of skin flap,as well as the DASH score of the hand fimction have been recorded and analyzed through follow-up patients,to observe the effects on repairing soft tissue defects in the two groups.Results:All transplanted tisssues were all survived in the observation group and control group.Compared with control group,the sense of touch,temperature sense,monofilament,two-point discrimination,scar contracture of the observation group were better(P＜0.05),the incidence of bloat was lower (P＜0.05).The DASH scores were 29.56± 2.14,38.13± 3.12 in the observation group and control group,which was significantly lower in the observation group than that of the control group(P＜0.05).Conclusion:The clinical efficacy of the dorsal neurocutaneous vascular flap is better than that of abdominal skin flap on repairing soft tissue defects of the thumb distal.For no injury for major vascular nerves,little influence on donor area,being simple to operate,being better feelings of the finger pulp,appearance,dorsal neurocutaneous vascular flap on repairing soft tissue defects of the thumb distal is an ideal choice.

Objective We aim to objectively evaluate the influence of six-character formula on patients with stable chronic obstructive pulmonary disease (COPD).Methods The randomized controlled trials (RCTs) which investigated the influence of six-character formula on patients with COPD were electronically searched in the databases such as China National Knowledge Infrastructure (CNKI),Chinese Science Technology Periodical Databases (VIP),Wanfang Data,PubMed,The Cochrane Library (Issue 6,2014) and ELSEVIER.According to the inclusion and exclusion criteria,the references was screened,the data were extracted and the methodological quality of the included articles was assessed.Then,Meta-analy-sis was performed using RevMan 5.3 software.Results A total of 10 studies involved,578 patients were included.The result of Meta-analysis showed that compared with the control group,six-character formula significantly improved six-minute walk distance,forced expiratory volume in a second (FEV1) and FEV1 predicted value,reduced the score of activity limitation and the impact of the disease in St George's respiratory questionnaire (SGRQ).the value of MD and 95％CI were 22.62 (10.49-34.75),0.10 (0.01-0.18),3.08 (0.18-5.97),8.69 (4.09-13.83),7.60 (2.34-12.85).However,there was no statistical difference in the score of symptom.Conclusions Six-character formula plays a significant role in the treatment of stable COPD.However,more studies in large scale and high quality are needed to verify the result.

OBJECTIVE:To establish a method for the concentration determination of vitamin A(VitA)in human serum,and apply it in healthy volunteers and hepatocirrhosis patients. METHODS:After liquid-liquid extraction,serum sample was deter-mined by HPLC. Using VitA acetic ester as internal standard,the separation was performed on Kromasil C18 column with mobile phase consisted of methanol-water (98∶2,V/V) at the flow rate of 1 ml/min. The wavelength was set at 325 nm,and the column temperature was room temperature. The sample size was 20 μl. RESULTS:The linear range of VitA were 0.012 4-3.210 μg/ml(r=0.997 2,n=5),and the limit of quantification was 0.012 4 μg/ml. Inter-day and intra-day RSD ranged 1.66%-2.97%;sample re-coveries were 98.18%-99.56%;extraction recoveries were 89.59%-91.38%. Average blood concentration of VitA were(0.71±0.08)μg/ml in 24 healthy volunteers and (0.28 ± 0.06)μg/ml in 24 hepatocirrhosis patients. There was statistical significance in average blood concentration of VitA between healthy volunteers and hepatocirrhosis patients in different age groups (P<0.05). CONCLU-SIONS:The method is simple,rapid,sensitive and accurate,and can be used for the concentration determination of VitA in serum of healthy volunteers and hepatocirrhosis patients.

Objective To explore the clinical efficacy of indwelling suture in preventing re-adhesion of fallopian tube after fallopian tube recanalization(FTR). Methods Screen 93 patients with fallopian tube obstruction and FTR indications of prospective, the patients without other interference factors of infertility, they were randomized with random sampling into two groups (treatment group 50 and control group 43)and treated by FTR,then the treatment group with indwelling sutures in fallopian tube for 3 days, the control group were infused lipiodol into the tube and with a intrauterine cavity perfusion in 3 days. The two groups received followed up examination at 2,6 months after operation ( a treatment was repeated with the case of re-obstruction) . Follow-up for 12 months to appraise the pregnancy rate and the influence of pregnancy competence of tube with indwelling suture(6 months after operation, to collect and compare the pregnancy rate and ectopic pregnancy rate of patent tube in two groups). Results The tubal patency rate were 89.8%(53/59),89.5%(51/57)of treatment group at 2,6 months after operation and the control group were75.9%(44/58),75.0%(39/52), there was a significant difference between the two groups(2 m:χ2=4.027, P<0.05;6 m:χ2=3.958,P<0.05). One year after operation,the pregnancy rate of treatment group was 43.2%(16/37) , the control group was 20.6%(7/34) ,there was a significant difference(χ2=4.152,P<0.05). Six
months after operation, the pregnancy rate and ectopic pregnancy rate of patent tube in treatment group were 21.6%(11/51),2/11, the control group were15.4%(6/39),1/6, there was no significant difference between them(pregnancy rate:χ2=0.552,P>0.05). Conclusions The indwelling suture of fallopian tube can prevent re-adhesion better after FTR, then improve the long-term recanalization rate and the pregnancy rate. There is no change on the pregnancy competence of fallopian tube.
