Objective To compare the clinical efficacy of intralesional betamethasone versus triamcinolone acetonide acetate in the treatment of active alopecia areata. Methods A total of 160 patients with active alopecia areata were divided into two groups, test group (n = 100) treated with intralesional betamethasone, and control group (n = 60) treated with intralesional triamcinolone acetonide. Both injections were given once every 3 weeks for 12 consecutive weeks. Results After 12-week treatment, the cure rate, response rate, and total response rate were 60.0%, 32.0% and 92.0% in the test group, respectively, compared to 41.7%, 31.67% and 73.3% in the control group, respectively. A significant increase was observed in the cure rate and response rate in the test group compared with the control group (χ2 = 10.25, 5.06, P < 0.01 and 0.05). During the treatment course, 8 (8%) patients in the test group and 9 (15%) patients in the control group developed localized atrophy of the scalp; 8 (8%) patients in the test group and 3 (5%) patients in the control group developed localized folliculitis; no significant difference was observed between the two groups in the occurrence of adverse reactions (P> 0.05). Conclusion Intralesional use of compound betamethasone injection has a notable therapeutic effect on alopecia areata.

Chronic osteomyelitis is one of the most common disorder in clinic. In recent years due to diabetes, peripheral vascular disease and trauma induced disease increased, the prevalence rate increased. With the development of magnetic resonance imaging and CT imaging technology, it greatly improved the accuracy of clinical diagnosis of chronic osteomyclitis and ability to describe the infection characteristics, and provide a reliable basis for clinical treatment. The current research on chronic osteomyelitis mainly concentrated on the aspects of imaging applications and ways of using antibiotic optimization control inflammation, defect restoration and reconstruction of blood supply and treatment. But the best time to the antibiotic therapy and the use of program is still uncertain, for after debridement, bone grafting time and defect repair function of fast recovery still need further research.

Objective To evaluate the acute and long-term results of stenting for left main coronary artery (LMCA) bifurcation lesions. Methods Forty consecutive patients with LMCA bifurcation lesion and normal left ventricular function were included. Sirolimus-eluting stents were performed in all patients. Results (1)The average diameter of LMCA was (0.81?0.48)mm before stenting and increased to (3.53?0.22)mm after stenting.(2)The procedural success rate was 100.0%. In-hospital events including stent thrombosis,Q-wave myocardial infarction,and emergency bypass surgery did not occur in any patients,and non-Q-wave MI in one patient (2.5%).(3)Clinical follow-up was obtained in all patients at (8.43?3.24) months. There were no death and no myocardial infarction during follow-up. The major adverse cardis events rate was 20.0%.(4)The angiographic follow-up rate was 67.5% (27 of the 40 eligible patients),and the restenosis rate was 18.5% (parent vessel only 11.1%,side branch only 3.7%,and both 3.7%).(5)Different type of operation had no influence on restenosis rate during angiographic follow-up. Conclusion Sirolimus-eluting stent implantation for LMCA bifurcation stenosis appears safe and effective with regard to acute and midterm complications.

Objective:To investigate the clinical efficacy and patient and partner's satisfaction with penile prosthesis implantation(PPI) for treating Chinese patients with severe erectile dysfunction(SED).Methods:One hundred and sixty-eight SED patients were successfully treated by PPI from July 2000 to June 2010.Of the 146(86.9%) patients who had been followed up over 6 months post-operation,36(24.7%) had been implanted with one piece malleable prosthesis(AMS650) and 110(75.3%) with three piece inflatable prosthesis(AMS700CXM).All the patients had been followed up by using international index of erectile dysfunction(IIEF5),Quality of Life Score(QOL) for evaluating clinical efficacy and using Visual Analogue Scale(VAS) for evaluating patient and partner's satisfaction and the duration of the follow-up was 6 to 119 months.Results:The mean age of patients was 35.9?12.1 years(20 to 75 years),All the operations were successful and sexual intercourse with PPI was performed post 4 to 6 weeks without severe complications like infection and erosion.The prosthesis survive rate and frequent sexual intercourse rate were 98.6% and 87.7% respectively.IIEF5 scores pre and post PPI were 6.3?1.7 and 21.3?1.6 respectively,the QOL scores pre and post PPI were 5.1?0.9 and 1.5?0.5 respectively,and both of them showed significant improvement(P

Objective To assess the causes of sildenafil failure and the feasibility of successfully rechallenging non-responding patients. Methods A total of 126 consecutive erectile dysfunction (ED) patients from Jan 2009 to Dec 2009 who claimed poor response to sildenafil (sildenafil 100 mg on demand, at lease 4 epiodes) were enrolled into the study. All patients received sexual reeducation and were treated with sildenafil, taken on a daily dose of 50 mg for 4 weeks. The International Index of Erectile Function-5 (IIEF-5), Rigiscan, serum testosterone or penile Doppler were used to evaluate ED and the cause of on-demand sildenafil failure. End point efficacy of rechallenging was evaluated using the IIEF-5 and the sexual encounter profile (SEP) 'Were you able to insert your penis into your partner's vagina?' and 'Did your erection last long enough to achieve successful intercourse?'. Results The recruited patients comprised of 41 cases with psychological ED, 39 cases with hypogonadism ED, 28 cases with diabetes mellitus ED and 18 cases with vascular ED. Compared with pretreatment and on-demand sildenafil baseline, daily administration of sildenafil significantly enhanced all efficacy outcome variables. The IIEF-5 was significantly improved after daily sildenafil (12.3 ± 2.9 vs18. 8±4.4, P＜0.01), 78 patients responded to daily sildenafil. The overall salvage rate was 61.9%(78/126). Conclusions Sexual reeducation and daily administration of sildenafil may be able to salvage many patients with ED who were sildenafil non-responders.

Objective To estabalish a new conception, Erectile Dysfunction-no sexual life (ED-NS), so as create an evaluating questionnaire, Self-estimation Index of erectile function-No sexual life (SIEF-NS) so as to investigate its clinical reliability. Methods The conception of ED-NS was identified and the SIEF-NS questionnaire was established. Patients who complained of ED-NS and normal controls were enrolled into the research and assessed the erectile function was assessed with SIEF-NS.The SIEF-NS includes 12 questions, such as sexual libido, general erectile function, nocturnal penile erection, erectile function during foreplay, erectile function during audio-video sexual stimulation,confidence, depression, etc and each question has 5 point scales. Results Sixty-one ED-NS patients and 57 controls were enrolled into the study and assessed erectile function with SIEF-NS. The mean score of each question and integral score of SIEF-NS in ED-NS patients were significantly different from normal controls (P＜0. 05). When the integral score was 35 points according to the ROC curve of integral score, the sensitivity of SIEF-NS was 88.5% and specificity was 96. 5%. Conclusions ED-NS is a new conception to define patients who have erectile dysfunction without sexual life. SIEFNS is suggested to be a useful method for the evaluation of ED-NS patients.

Objective To explore the value of PET-CT and CT in the assessment after radiofrequency ablation (RFA) in lung cancer.Methods Eighteen patients were randomly divided into short-term group ( 8 cases) and long-term group ( 10 cases).Patients in short-term group received PET-CT and CT examination within 10 days after RFA therapy,whereas those in long-term group got PET-CT and CT examination within 2 months after RFA therapy.The value of PET-CT and CT after RFA therapy through the result of the image was compared between two groups.Results All patients were classified as stable disease in CT,while in PET-CT assessment,33.33％ (6/18) of the patients presented complete remission and 66.67％ (12/18)presented partial remission.37.50％ (3/8) of short-term group presented complete remission,62.50％ (5/8) of short-term group presented partial remission.30.00％ (3/10) of long-term group presented complete remission,70.00％(7/l0) of long-term group presented partial remission.Conclusion PET-CT is superior to CT in the assessment of the effectiveness of RFA therapy,and there is no difference between short-term and long-term PET-CT examination,therefore early PET-CT is more with clinical significance.

Objective To review the clinical manifestation,pathological characteristics,treat ment and prognosis of malignant mesothelioma of the tuniea vaginalis testis.Methods A case of ma lignant mesothelioma of the tunica vaginalis testis was reported and relative literature was reviewed.A34 year old man was admitted to hospital with a history of aggravated hydroeele for 5 years.A hardtumor was palpated above the right testis,which was smooth and slight tenderness.The level of β-hCG and AFP was normal.Ultrasonography revealed a 2.05 cm× 1.97 cm,well demarcated,mixedecho tumor.Results An operation was performed to incise the tumor and tunica vaginalis undersubarachnoid space block anesthesia.The tumor was histologically diagnosed as low potential malig nant mesothelioma of the tunica vaginalis testis.Microscopic examination showed that the tumor wasmalignant with a biphasic pattern composed of epithelial and stromal components.The former compo nent was dominant.The epithelial cells proliferated obviously with atypia and mitosis.Immunohisto chemical staining showed cytokeratin and vimentin were strongly positive.The capillary,lymph ves sel,spermatic cord and testis were not infiltrated.Right radical orchiectomy and right scrotectomywas performed one month after the first operation.There was no evidence of relapse during 38 monthfollow up after operation.Conclusions The major symptom of patients with malignant mesotheliomais hydrocele,malignant mesothelioma is diagnosed by histopathology.Due to the invasive potential ofthis disease and the risk of tumor recurrence,radical orchiectomy and close follow up are strongly rec ommended.

Objective To evaluate the efficacy of microvasoepididymostomy for the treatment of obstructive azoospermia. Methods Ninety-eight patients were confirmed as obstructive azoospermia by infertility investigations.The mean (range) age was 31 (20-43) years.The mean duration of obstruetion was 4 years.All patients were seen by the surgeon for a complete history and physical examination.Semen analyses proved azoopermia,serum levels of sexual hormone were normal and testicular function for production of sperms were normal certified by biopsy.All patients with suspected epididymal or vasal obstruction were offered scrotal exploration.The decision for microvasoepididymostomy was made during surgery,based on the pateney of the vas towards the abdomen documented by saline and sperm fragments containing in the epididymal fluid on intraoperative light-microscopic examination.Microvasoepididymostomy was performed in 58 patients documented epididymal obstruction The initial semen analysis was then done after usually 3 months postoperatively.Patency was arbitrarily defined as＞10 000 sperm/mL in ejaculate in at least one semen analysis after surgery.Postoperative patency rate and postoperative impregnation rate were followed. Results Fifty patients were followed up for 3-29 months,8 cases lost.Sperm was found by semen analysis in 36 patients.Sperm density was 4×104-2×108 sperms/ml and motility was 2%-70%.Semen analysis reveals azoospermia in 6 patients and the patients were counseled to undergo further testing to determine the ultimate outcome of the procedure.Natural conception occurred in 14 patients followed for more than 12 months.The overall pateney rate was 72%(36/50).Among patients with a follow-up of＞6 months,the natural paternity rate was 28%(14/50).The median time to achieve a natural pregnancy was 6.6 (4.0-10.0)months. Conclusion A more favourable patency can be achieved using microsurgical intussusception vasoepididymostomy and a part of patients with obstructive azoospermia can be cured by this means.
