OBJECTIVE:To establish the quality standard of Tangkang capsule. METHODS:Momordica charantia L. and Euonymus alatus(Thunb.)Sieb.,the main ingredients in Tangkang capsule including were identified by TLC, meanwhile, the content of total Momordica charantian saponin was determined by UV-Vis. RESULTS: The TLC spots were clear and the separation degree was good. The linear range of Ginsenoside Rg1 was 72～252 ?g(r=0.999 7) with average recovery rate at 100.68% (RSD=1.43%,n=6). CONCLUSION: The established quality standard can be used for the quality control of this Tangkang capsule.

Objective To observe the efficacy of bioelectric stimulation of the pelvic floor combined with acupuncture in treating detrusor urine weakness after transurethral resection of the prostate (TURP) in patients with prostate hyperplasia.Methods Forty-seven cases with detrusor urine weakness after TURP were randomly divided into an experimental group and a control group.All of the patients received routine bladder function training and medication.In addition,patients in the experimental group were treated with bioelectric stimulation of the pelvic floor and with acupuncture.The differences between the two groups were compared using the International Prostate Symptom Score (IPSS),maximum urine flow rate (MFR),average flow rate (AFR),detrusor pressure at peak flow (PdetQmax) and residual urine volume in the bladder.Results No significant difference was found between the two groups before treatment,but at two weeks after treatment MFR,AFR and PdetQmax were significantly higher in the experimental group than in the control group,and residual urine volume and IPSS were significantly lower.Conclusion Bioelectric stimulation of the pelvic floor combined with acupuncture is more effective than routine bladder function training and medication alone for alleviating detrusor urine weakness after TURP.

Objective To compare the clinical effect of single-row (SR) and double-row (DR)rotator cuff injury repair.Methods Twenty-three patients with rotator cuff injury were randomized into SR group(12 patients) and DR group (11 patients) by ranom digits table.Two anchors and simple sutures were applied in SR group,three anchors and medial mattress sutures were applied in DR group.Clinical function were compared after operation 24 months,included pain visual analogue scale (VAS) scores,Constant scores,American Shoulder and Elbow Surgeons (ASES) scores,University of California at Los Angeles (UCLA) scores,range of shoulder motion (anteflexion,adtorsion conclination,external rotation),operation time and patient's satisfaction were compared.Re-tear rate and clinical function were also analyzed.Results The operation time in SR group was shorter than that in DR group [(115.8 t25.0) min vs.(124.5 ± 19.7)min,P =0.033].The scores of VAS,Constant,ASES,UCLA in two groups had no significant difference (P ＞ 0.05).The full-thickness re-tear in SR group was 2 patients,in DR group was 2 patients,there was no significant difference (P ＞ 0.05).The full-thickness re-tear and part-thickness re-tear in SR group was 7 patients,in DR group was 2 patients,there was significant difference(P=0.041).Furthermore,the scores of VAS,Constant,ASES,UCLA had no significant difference (P＞ 0.05).Conclusion Compared with SR,2-5 cm rotator cuff injury repaired by DR has no obviously advantage.

Objective To explore the clinical effect and safety of levosimendan,milrinone,and dobutamine in treatment of patients with ADHF.Methods All 336 patients with ADHF accepted in Xi'an Center Hospital from April 2013 to April 2016 were selected and divided into group A,B,and C with 112 cases in each group.Patients in three groups were given levosimendan,milrinone,and dobutamine respectively.Then the clinical effect,hemodynamics,serum indexes,and safety of two groups were observed and compared.Results The total efficacy of group A (90.18％) was obviously higher than group B (58.93％) and group C (65.18％) with statistically significance (P ＜ 0.05).PCWP,PAMP,RAP,and SVR of three groups after treatment were lower than before (P ＜ 0.05).And PCWP,PAMP,and SVR of group A were obviously lower than those of group B and C (P ＜ 0.05).RAP among three groups after treatment had no difference.NT-proBNP,ET-1,and NE of three groups after treatment were lower than before (P ＜ 0.05),and group A was obviously lower than group B and C (P ＜ 0.05).Adverse reaction rate of group A was obviously lower than that of group B and C with statistically difference (P ＜ 0.05).Conclusion Levosimendan has better effect and safety than milrinone and dobutamine in treatment of patients with ADHF,which is worth clinical application.

Objective To evaluate the value of retroperitoneal laparoscopic adrenalectomy for benign adrenal tumors.Methods From Mar.2009 to Oct.2011,36 patients with adrenal tumors received retroperitoneal laparoscopic adrenalectomy in the First People's Hospital of Shangqiu.During the operation,3 trocars were introduced into the lumbar region to establish retroperitoneal space.Afterwards,the tumor was removed by using a harmonic scalpel.Results The procedures were successfully completed in 19 cases of adrenocortical adenoma,14 cases of pheochromocytoma,2 cases of adrenal cyst and 1case of adrenocortical carcinoma without blood transfusion.The median operation time was 90 min,ranging from 45 min to 180 min.The median intraoperative blood loss was 76 ml,ranging from 30 ml to 700 ml.Drainage tubes were removed 2 days after the operation and the patients were discharged from hospital 3 to 5 days after operation.2 cases were converted to open surgery ( one because of the adhesion between the tumor and vena cava,the other because of the size (about 6.0 cm) of the tumor).The median follow-up time was 12 months,ranging from 3 to 24 months.One patient showed regional subcutaneous emphysema after the surgery and was cured spontaneously.The patients were followed up for 3 to 24 months with the medium of 12 months.Normal blood pressure was achieved in 30 patients in 3 months,while oral antihypertension drugs were still needed for the other 6 patients (2 patients converted to open surgery included).No regional recurrence or death happened during the follow-up.Conclusion Retroperitoneal laparoscopic adrenalectomy can be a safe and effective choice for adrenal tumors,with advantages of small trama,quick recovery,short postoperative hospital stay etc.

The author thinks the key to the problem is to prepare lessons wholeheartedly.The contents of preparing lessons consist of preparing teaching contents,preparing teaching methods and preparing for students.The secondary problem is the skill of classroom teaching.It consists of how to introduce new lesson,how to teach the key points elaborately and how to mobilize the enthusiasm of the students,etc.

Introduction is the beginning and epitome of a subject. To teach introduction well can arouse students’ great interest in this subject and strong thirst for knowledge. This article introduces experience and understanding of the author who have taught introduction class in medical immunology for many years.

Objective To investigate the effect of laparoscopic surgery on primary aldosteronism (PA).Methods 20 cases of PA treated by laparoscopic surgery from Jul.2009 to Jul.2011 were retrospectively analyzed,among whom 17 cases had adrenocortical adenoma and 3 cases had adrenal cortical hyperplasia.Results The mean surgical time was 63 (35 ～95 )min,the mean intraoperative blood loss was 50( 25 ～ 110)ml,and the mean hospital stay was 5.8 (4 ～ 8)d.Complication during or after surgery happened to 2 patients.They are both with light cutaneous emphysema.During the medium follow-up of 12(6～ 18 )months,serum potassium levels of all patients were normal,and 3 patients with high blood pressure still need hypotensive drug.Conclusion Laparoscopic resection of the whole or partial adrenal tumor is minimally invasive,safe and with confirmed effects,making it the preferred method for PA.
