ObjectiveTo explore the suitable division of male genitalia subunits and the effectiveness of large-area perineum defect repair under its guidance.MethodsAccording to the anatomical and functional characteristics of male genitalia, the subunit division scheme was proposed: area Ⅰ, glans penis; area Ⅱ, body of penis; area Ⅲ, scrotum; area Ⅳ, scrotum. Between April 2017 and July 2019, 12 patients with large genitalia defects were treated, with an average age of 60.9 years (range, 57-66 years) and an average disease duration of 2.7 years (range, 2-5 years). The defect area involved area Ⅰ in 1 case, area Ⅱ in 7 cases, area Ⅲ in 5 cases, and area Ⅳ in 8 cases; the size of area ranged from 6 cm×4 cm to 23 cm×16 cm. The causes of defect included 3 cases of trauma, 6 cases of Paget disease, 2 cases of squamous cell carcinoma, 1 case of spindle cell tumor. According to the design of the corresponding repair scheme, the main repair methods were to rotate and advance the skin flap and pedicled skin flap in the same area. When the defect was large, the free skin flap transplantation, free skin grafting, and free mucosa transplantation were used to repair the defect.ResultsAll the patients were followed up 6-13 months with an average of 8.6 months. Skin flap, skin graft, and mucosa survived in one stage in 10 patients; infection occurred in 1 case after the scrotal flap of area Ⅲ was transferred to repair the defect in area Ⅱ, 1 case had distal venous crisis at 2 days after repair area Ⅲ defect used free anterolateral thigh flap, and after active treatment, the condition improved. The appearance of the receiving area and the supplying area was good, and the local feeling was recovered satisfactorily. The range of motion of hip joint was good in 10 cases, and 2 cases were slightly stretched but did not affect normal life. All patients had normal urination and defecation function, and were satisfied with the treatment effectiveness.ConclusionThe subunits of male genitalia can be used to guide the repair of the defect, which can better restore the physiological appearance and function, and has positive clinical significance.
Objective To explore the sonographic features of testicular torsion in adult males (≥25 years). Method We retrospectively analyzed the clinical, pathological and sonographic data of 79 adult male patients with testicular torsion, in whom 20 underwent resection of testis and 59 retained testis in West China Hospital from September 2006 to March 2017. Results There were 56 patients with spermatic cord nodules or mass with the largest mass of about 36 mm ×31 mm; the scrotal wall thickened in 48 patients with the thickness of 5–10 mm; axial changes of the affected testis were found in 24 patients; there were 61 patients with testicular growth in the affected side, while the affected testis was reduced in 7; there were 67 patients with asymmetric echo in the affected side, and the maximum hypoechoic area was about 36 mm×26 mm; the epididymis of the affected side in 35 patients with were unclear, and the epididymis of the affected side was enlarged in 19; 25 patients had hydrocele of testis; there was no blood flow in 49, blood flow reduced in 25, and blood flow increased in 5. Four patients were diagnosed by contrast-enhanced ultrasound, and there was no enhancement in 3 and partial enhancement in 1. Conclusion The sonographic features of testicular torsion in adult males are obvious, and the early diagnosis of testicular torsion can be confirmed by contrast-enhanced ultrasonography.

ObjectiveTo investigate the prevalence and risk factors of chronic obstructive pulmonary disease (COPD) in urban and rural male residents of Chengdu city. MethodsA cross-sectional survey about the incidence of COPD using cluster random sampling methods was carried out from February to December 2010 among male residents aged 40 to 70 years in four communities in Chengdu city, which was conducted by applying questionnaire survey, physical examination, portable spirometry, etc. Data was analyzed by using SPSS 18.0 software, and the risk factors were also analyzed by using the multivariate logistic methods. ResultsA total of 631 male residents were included, 301 urban and 330 rural. The results showed that: after population standardization, among male residents aged 40 to 70 years in four communities in Chengdu city, the overall prevalence of COPD was 7.95%, and the prevalence was 12.07% in rural area and 7.05% in urban area (P < 0.001). The results of multivariate logistic regression analysis showed that area, age, BMI and smoking volume were the main risk factors of COPD among male. ConclusionThe prevalence of COPD in Chengdu city is relatively higher, which is much higher in rural area than that in urban area. The risk factors are various, and thus comprehensive prevention and treatment of COPD should be emphasized.
Objective To systematically review the efficacy and adverse events of alendronate on bone mineral density and fractures in men with osteoporosis. Methods We electronically searched MEDLINE (1990 to 2005), EMBASE (1990 to 2005), The Cochrane Library (Issue 3, 2005), Controlled Trials Register and The National Research Register, CBM disc, VIP, and CNKI. We also handsearched some related journals. The search was conducted in Nov., 2005. The quality of included randomized controlled trials (RCTs) was evaluated and meta-analysis was conducted by RevMan 4.2.8. Results We identified 7 studies including 817 patients. Sufficient evidence showed that alendronate plus calcium was superior as preventive treatment to calcium in increasing the bone mineral density (SMD 0.59, 95% CI 0.15 to 1.03, P=0.009) of the lumbar spine. The incidence of withdrawal and lost to follow-up due to adverse events of the alendronate plus calcium was lower than that of calcium (RR 0.32, 95% CI 0.11 to 0.87). Two studies showed that alendronate was superior to placebo in increasing the bone mineral density in men with osteoporosis but with no significantly statistical difference in reducing fractures. Two studies showed alendronate was superior to alfacalcidol in increasing the bone mineral density and reducing the vertebral fractures in men with osteoporosis. One study showed alendronate was not superior to calcitonin or alfacalcidol in increasing the bone mineral density in men at high risk of osteoporosis. One study comparing anledronate or parathyroid hormone with combination of these drugs in men with osteoporosis suggested that anledronate wasn’t superior to parathyroid hormone in increasing the bone mineral density, and the combination did not show any difference compared to parathyroid hormone alone. Conclusions Alendronate is more effective in prevention and treatment of men with osteoporosis compared to placebo. Alendronate is more effective than alfacalcidol in increasing bone mineral density and reducingvertebral fractures in men with osteoporosis. Alendronate is not superior to alfacalcidol or calcitonin in increasing the bone mineral density in preventing men osteoporosis. Alendronate compared to combination of parathyroid hormone does not show more effectiveness in increasing the bone mineral density in men with osteoporosis. More RCTs of high quality, especially multiple center trials are needed to generate ber evidence.

Objective To investigate the correlation between glycosylated hemoglobin A1c (HbA1c) and severity of coronary artery lesions in young men with acute myocardial infarction (AMI). Methods Total 278 young men with AMI less than 45 years old were retrospectively studied, and all of them were admitted to hospital from January 2009 to December 2011, and had undergone coronary angiography. According to the results of coronary angiography, the patients were divided into three groups based on the number of artery lesions: the single group (156 cases), the double group (64 cases) and the triple group (58 cases). The relationship between the severity of coronary artery lesions and the following factors were observed: HbA1c, systolic blood pressure (SBP), diastolic blood pressure (DBP), hemoglobin (Hb), serum uric acid (UA), total cholesterol (TC), triglyceride (TG), high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C), body mass index (BMI), smoking history, drinking history and family history of early coronary artery disease. Results a) HbA1c levels were gradually raised in all the three groups, but the single group (6.39±1.67%) was significantly lower than the double group (6.91±1.63%) and the triple group (7.41±2.12%), with significant differences (Plt;0.05); the HbA1c level of the single group was significantly lower than the triple group in both the ST-segment elevation AMI (6.42±1.68% vs. 7.17±1.86%, Plt;0.05) and the non-ST-segment AMI (5.57±0.37% vs. 8.56±2.83%, Plt;0.05); the HbA1c level of the single group was significantly lower than the triple group in patients with diabetes millitus (8.31±1.83% vs. 8.59±2.02%, Plt;0.05) and in patients without diabetes millitus (5.56±0.33% vs. 5.74±0.37%, Plt;0.05); b) There were significant differences in SBP, TC, HDL-C, LDL-C and drinking history between the single group and the other two groups (all Plt;0.05), and there were significant differences in DBP and TG between the single group and the double group (all Plt;0.05); and c) The results of logistic regression analysis showed that, LDL-C (OR=1.790), HbA1c (OR=1.287) and SBP (OR=1.042) were the independent risk factors (all Plt;0.05) for multiple lesions in coronary arteries of young men with AMI. Conclusion Glycosylated hemoglobin A1c is an independent risk factor for multiple lesions in coronary arteries of young men with AMI.
