Objective To observe the effect of Qingrelifei decoction on hemorrheology and nail bed in patients with chronic obstructive pulmonary disease (COPD). Methods Sixty cases of COPD were divided into 2 groups randomly, the treatment group was 30 cases and the control was 30 cases. The control group was treated with oxygen therapy, bronchodilators, antibiotics, glucocorticosteroid therapy. The treatment group was given Qingrelifei decoction additionally. Indexes of hemorrhelolgy and nail fold microcirculation were detected before and after treatment. Results The whole blood viscosity, plasma viscosity and erythrocyte sedimentation rate decreased while hematocrit increased after medication, there were obvious differences in both groups (P

Objective To provide reference for further perfection and revision of standards relevant to limb injury by comparing the evaluation results of different disability standards of long bone fracture. Methods Thirty cases were selected from the long bone fracture cases accepted by our institution in 2018. These cases include 5 cases of shoulder, elbow, wrist, hip, knee, ankle joints, respectively, to investigate the degree of loss of function of joints after long bone fracture. Disability evaluation was made according to Classification of the Impairment Related To Injury （hereinafter referred to as Classification）, Assessment for Body Impairment of the injured in road traffic accidents （now repealed, hereinafter referred to as original Road Standard） and Identifying Work Ability-Gradation of Disability Caused by Work-related Injuries and Occupational Diseases （hereinafter referred to as Work Standard）. The disability evaluation results of every domestic standard were compared with the joint damage rate of Guides to the Evaluation of Permanent Impairment （hereinafter referred to as GEPI）. Results The functional loss rate of joints （except ankle） was 26%-48%，and the ankle functional loss rate was 51%-64%. The mean value of GEPI joint impairment rate of the joints was 13%-22%, with the fluctuation range less than 10%. The rate of level 10 disability was 100% according to the Classification. The rate of level 10 disability was 27%, the rate of level 9 disability was 6% and 67% were not disabled according to the original Road Standard. The rate of level 10 disability was 10% according to the Work Standard and 90% had a disability above level 10 （47% were classified as level 7 disability）. Conclusion The people with limb joint dysfunction in this study had evaluation results with a smaller fluctuation range and better consistency according to the Classification and GEPI. The evaluation results according to the original Road Standard and the Work Standard has a less consistency. The Classification is more similar to GEPI and is more reasonable.

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.

Objective To compare the circumferential approach and suprapubic approach for correcting the concealed penis. Methods Thirty-four patients received circumferential approach (group A,18 cases)or suprapubic approach(group B,15 cases)randomly for the concealed penis.The length of penis without erection before and after surgery treatment,patients'satisfaction and surgical complications were evaluated.All the patients were followed at least 6 months after operation.Results The penile length before and after surgery in group A were(1.78±0.41)cm vs(3.97±0.47)cm,the length of the postoperative penis was significantly longer than that of the preoperative penis(P<0.01).83%of those in group A(15 cases)were satisfied with the cosmic results.The length of preoperative and postoperative penis in group B were(2.07±0.53)cm vs(4.05±0.81)cm respectively,the length of the postoperative penis was significantly longer(P<0.01).Satisfaction was 87%(13 cases).The postoperative penile length between the 2 groups was not different(P> 0.05).Prepuce edema was reported to Occur in 56%and 13%in group A and group B and spontaneously disappeared within 3 months.Fat synchysis occurred in 2 of group B. Conclusions The cosmic effect of the 2 surgical approaches is similar,but circumferential approach is simpler.There is no serious complication in those receiving circumferential approach.

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.

ObjectiveTo assess the cause of tadalafil failure and the feasibility of successfully rechallenging nonresponding patients.Methods A total of 80 consecutive erectile dysfunction ( ED ) patients who claimed poor response to tadalafil were enrolled into the study.A self-administered tadalafil-use questionnaire composed of eight questions was applied to assess how they had used tadalafil.Subjects were given thorough instruction based on individual answers and four doses of tadalafil 20mg.After a 2-week follow-up,end point efficacy of rechallenge was evaluated using the sexual encounter profile (SEP),which was recommended by international advisory panel in 2004.ResultsA total of 45 subjects had one or more areas of major suboptimal use of tadalafil:21.2％ did not know that sexual stimulation was necessary for tadalafil to work,87.5％ attempted to use tadalafil less than four times,57.5％ took a maximal dose less than 20 mg,and 84％ felt nervous or anxious.Of the 65 patients undergoing tadalafil rechallenge,30 patients answered “yes” to SEP2 and SEP3.The response rate to rechallenge was 46.2％ ( 30/65 ).ConclusionsInappropriate use of tadalafil was major cause of tadalafil non-pesponse.The efficacy of tadalafil could be improved to a better extent by education of patients.

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 investigate the relationship between plasma triglycerides ( TG ) , cholesterol (TC)levels and breast cancer.Methods 105 cases of breast cancer(age from 22 to 69 years)and 261 cases of healthy control(age from 16 to 52 years)admitted from May.2014 to Oct.2014 were studied.TG and TC were tested.Subgroup analysis was performed by age (<35, 35-45, ≥45 years) and BMI( <18.5, 18.5-24, ≥24).Results TG level in breast cancer group was significantly higher than that of the healthy control group (t=-3.97,P=0.00), and TC level was lower than that in the healthy control group (t=2.49, P=0.01).TG lev-el of breast cancer patients≥45 years old was higher than that in the healthy control group ( t=-4.31, P=0.00).TC level of breast cancer patients <35 years and from 35 to 45 years was lower than that of the healthy control group(t=3.12, P=0.00及t=2.41, P=0.02); TG levels in breast cancer group were significantly lower than those of the healthy control group for all BMI subgroup ( t=-3.67, P=0.01 for BMI<18.5; t=-3.87, P=0.00 for BMI from 18.5 to 24.0;t=-2.01, P=0.04 for BMI≥24).TC level of breast cancer patients was higher than that of the healthy control group for patients whose BMI <18.5(t=-3.41, P=0.01) and it was lower than that of the healthy control group for patients whose BMI≥24.Conclusions The relation-ship between TG , TC and breast cancer is associated with age .Compared with healthy group , breast cancer pa-tients≥45 years have a higher TG level and breast cancer patients <45 years have a lower TC level .

Objective To assess the causes of erectile dysfunction (ED) after spinal or pelvic injuries.Methods From 2005 to 2009,a total of 67 patients who complained of ED after pelvic fracture or spinal injures were evaluated with the average patient age of 32 yrs (18 to 64) and average injury period of 38 mon (3 -144).Of the 67 patients,56 had pelvic fractures (84％) and 11 patients had spinal injures ( 16％ ).All patients reported normal erectile function before the injuries.All patients answered IIEF-5 and underwent nocturnal penile tumescence (NPT) tests (Rigiscan assessment system,continuing three nights).If resuls of the test were abnormal,color penile duplex ultrasound ( CDU ) with intracavernous injection were performed.Normal nocturnal erectile function was defined as at least three tumescence periods lasting more the 10 minutes with rigidity at the penile tip of at least 70％.Patients with abnormal nocturnal erectile function were diagnosed with organic ED.Patients who achieved a fully erect penis after intracavernous injection,and who had a peak systolic velocity ( PSV ) of less than 25 em/s on CDU were diagnosed with arterial ED.Patients with a PSV of more than 25 cm/s and an end diastolic velocity (EDV) of more than 5 cm/s on CDU indicated venous leakage.Patients with organic ED who had normal vascular function on duplex ultrasound were diagnosed with neurogenic ED.Results All patients reported IIEF-5 less than 8,NPT tests showed that all patients had organic ED.Of the patients with pelvic fracture,neurogenic ED,arterial ED and venous leakage was diagnosed in 24 patients (43％),22 patients (39％) and 10 patients (18％),respectively.However,the patients with spinal injuries were all diagnosed with neurogenic ED.Conclusions Pelvic fracture and spinal injury can cause organic ED.Vascular ED is common in pelvic fracture,however,neurogenic ED was the most common type of ED in spinal injury.
