Objective To explore the correlation between hematocrit and slow coronary flow (SCF) in male patients. Methods We studied 205 patients with angiographically no more than one stenosis lt;40% in each major coronary artery who had admitted to the department of cardiology of the Beijing Anzhen Hospital Affiliated to Capital Medical University from August 2011 to August 2012. According to the level of hematocrit, 101 patients were classified into the trial group whose hematocrit was more 42.9%, while 104 patients into the control group whose hematocrit was no more than 42.9%. Clinical variables were analyzed and compared between the two groups. Results The age was younger in the trial group than the control group, whereas the levels of white blood cell count, mean platelet volume, triglyceride, low-density lipoprotein cholesterol, left anterior descending artery (LAD) and right coronary artery (RCA) TIMI frame count and the proportion of SCF in the LAD were higher in the trial group than in the control group (Plt;0.05). The results of correlation analysis showed that, LAD TIMI frame count (r=0.238, P=0.001), proportion of SCF in the LAD (r=0.206, P=0.003) and RCA TIMI frame count (r=0.209, P=0.003) were positively correlated with hematocrit. The results of multivariate analysis (using logistic regression with adjusted confounding factors such as age) showed that, LAD TIMI frame count (OR=1.031, 95%CI 1.006 to 1.056, P=0.014), proportion of SCF in the LAD (OR=1.919, 95%CI 1.038 to 3.547, P=0.038) were independently correlated with hematocrit. Conclusion The proportion of SCF in the LAD is independently correlated to hematocrit, which suggested that increased hematocrit may contribute to the pathophysiological change of SCF in male patients.
Objective To explore the key influencing factors of HIV risk behavior among male who have sex with male (MSM). Methods 36 MSM subjects in a community were recruited for HIV risk behavior characteristics, social environment and the attitude of exposure of high risk sexual intercourse, using behavior scales and qualitative research methods. The collected data were orderly input and analyzed using Nvivo 8.0 software. Then, after three-level transcription, the data were further summarized and extracted based on the method of the grouding theory. Results The HIV Risk Assessment Questionnaire score of 36 subjects was 8.08±2.46, of whom, 72% scored at a medium level (5 to 10 scores) and 19% scored at a high level (more than 10 scores). The social support rating scale (SSRS) score was 32.38±5.99 in MSM population, lower than in undergraduates and floating population. The results of qualitative analysis showed that, after open coding, 11 key message and 4 categories contributed to HIV risk in MSM populaiton, including: a) low levels of fear for AIDS; b) male role and uncertain sexual orientation; c) low degree social support; and d) poor availability of condom in the setting of sexual intercourse. Conclusion The interventions against AIDS/HIV for MSM need to be further studied. Besides, we should strengthen the community intervention mode based on fear for AIDS, social support, and condom distribution methods
Objective To investigate the clinicopathological features, postoperative survival and prognostic influencing factors of male patients with hepatocellular carcinoma （HCC）. Methods The clinicopathological features and the follow-up data of 155 male HCC patients who received hepatectomy from Jan. 1995 to Dec. 2002 were retrospectively analyzed and the prognostic influencing factors were defined by uni- and multi-variate analysis. Results Compared with 24 female patients at the same period, males were about six-year older and both of their hepatitis B surface antigen (HBsAg) and liver cirrhosis positive rates were higher (P＜0.05)， but there were no significant differences of the other clinicopathological parameters between the male group and the female group. Multivariate analysis showed that Edmondson-Steiner grade and portal vein tumor thrombosis (PVTT) were two independent prognostic influencing factors of both the overall survival and the tumor-free postoperative survival of male patients with HCC, while satellite nodule and tumor size only influenced the overall survival. Conclusion The main clinicopathological features and the postoperative survival of male HCC patients were similar than those of female’s. Tumor differentiation and biological behaviors were major factors affecting postoperative survival of male patients with HCC.
Objectives To assess the effectiveness and safety of carnitine in the treatment of idiopathic asthenozoospermia. Methods The Cochrane Library, MEDLINE, EMbase, and CNKI were searched between Jan 1995 and Dec 2006. Both English and Chinese studies were included in the review if they were randomized controlled trials (RCTs) involving men with idopathic asthenozoospermia who were treated with carnitine. Trial screening, data extraction, and quality assessment of included trials were conducted by method recommended by Cochrane Collaboration. Statistical analysis was conducted using RevMan 4.2.10 software. Results Five RCTs involving 346 patients met the inclusion criteria, and 307 patients were included in the meta-analysis. The results showed that: after being treated with carnitine for 3 and 6 months, the difference of the patients’ partners’ spontaneous pregnancy rate between treatment group and control group was statistically significant with RR2.46 and 95% CI1.12 to 5.43 (Z=2.23, P=0.03). After being treated with carnitine for 3 and 6 months, the difference of forward motile sperm per ejaculate between treatment group and control group was not statistically significant with WMD 9.16 and 95%CI 0.14 to 18.18 (Z=1.99, P=0.05) and WMD 5.28 and 95%CI –4.45 to 15.01 (Z=1.06, P=0.29). After being treated with carnitine for 3 and 6 months, the difference of percentage of forward sperm motility between treatment group and control group was not statistically significant with WMD 14.56 and 95%CI –4.49 to 33.61( Z=1.50 ,P=0.13), and WMD 7.34 and 95%CI –5.93 to 20.61 (Z=1.08, P=0.28). After being treated with carnitine for 3 and 6 months, the difference of total motile sperm per ejaculate between treatment group and control group was not statistically significant with WMD 15.32 and 95%CI –1.34 to 31.98 (Z=1.80, P=0.07) and WMD 6.20, 95%CI –3.00 to 15.39 (Z=1.32, P=0.19).After being treated with carnitine for 3 and 6 months, the difference of percentage of total sperm motility between treatment group and control group was not statistically significant with WMD 2.97 and 95%CI –5.75 to 11.69 (Z=0.67, P=0.50) and WMD 4.48 and 95%CI-9.17 to18.14 (Z=0.64, P=0.52). After being treated with carnitine for 3 and 6 months, the difference of semen volume between treatment group and control group was not statistically significant with WMD –0.12 and 95%CI –0.55 to 0.30 (Z=0.57, P=0.57) and WMD 0.03 and 95%CI –0.38 to 0.45 (Z=0.16, P=0.87). After being treated with carnitine for 3 and 6 months, the difference of sperm concentration between treatment group and control group was not statistically significant with WMD 7.92 and 95%CI – 2.85 to18.68 (Z=1.44, P=0.15), and WMD 1.02 and 95%CI –5.09 to 7.14 (Z=0.33, P=0.74). Three RCTs reported that there were no serious side effects of carnitine during the treatment period. Conclusions The available evidence indicates that spontaneous pregnancy rate would increase with carnitine therapy, while it is short of improvement of semen parameters. There is no serious side effect of carnitine. Because of lack of evidence, we cannot conclude that carnitine is effective in improving the prognosis of infertile patients with idiopathic asthenozoospermia. More high quality trials with large sample are proposed.

ObjectiveTo summarize the progress of diagnosis and treatment in male breast cancer. MethodsThe literatures about the research progress of diagnosis and treatment in male breast cancer were reviewed. ResultsThe diagnosis of male breast cancer relied mainly on clinical manifestations and imaging manifestations, the main treatment of male breast cancer was modified radical operation, combining with radiotherapy, chemotherapy, endocrine therapy, and targeted therapy. ConclusionsThe treatment of male breast cancer is mainly reference the treatment of female breast cancer, which is lack of a clear standard of treatment. Indepth study on the molecular genetic level will provide more accurate care decisions for the treatment of male breast cancer.
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.
ObjectiveTo summarize the research progress of the cause, treatment, and other aspects in male breast cancer (MBC). MethodsThrough reading the related literatures, relevant literatures of MBC were reviewed. ResultsFamily history, BRCA1/2 mutation, the imbalance of level of estrogen and androgen, and other factors were risk factors of the MBC. Sentinel lymph node biopsy (SLNB) was feasible in the MBC. Radiotherapy could control local recurrence of MBC, and chemotherapy may be beneficial for long-term survival rate of MBC. The endocrine therapy principle for MBC was not exact as female breast cancer (FBC). ConclusionsMBC has many risk factors. Radiotherapy, chemotherapy, and endocrine therapy are benefit to MBC patients, but it still needs to be confirmed by many high-quality clinical researches of large sample.
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.
ObjectiveTo analyse baseline information, semen, sex hormones and sexual function to understand the differences between male patient with epilepsy(MPWE) and healthy men. At the same time, we preliminarily evaluated the risk factors related to reproductive function in MPWE to provide clinical method for reducing the risk of infertility.MethodsWe collected data of 112 MPWE in the Department of Neurology, First Affiliated Hospital of Dali University from February 2019 to February 2020. Sixty-seven healthy male volunteers matching the age of the survey group were selected. All men completed semen and sex hormone test. Men with sexual life experience completed the International index of erectile function scale (IIEF-5) and the Premature ejaculation diagnostic tool (PEDT). MPWE completed the Quality of life in epilepsy-1(QOLIE-31). The baseline data, semen quality, sex hormone level and sexual function questionnaire scores of MPWE and healthy controls were compared. In addition, according to the diagnostic criteria of abnormal male reproductive function, MPWE were divided into abnormal group and normal group. Single factor analysis and binary logistic regression analysis were used to preliminarily explore the related risk factors of reproductive function in MPWE.ResultsCompared with the healthy control group, the proportion of married and childbearing, testosterone level, sperm concentration, sperm survival rate and IIEF-5 score in MPWE were significantly reduced (P<0.05). Compared with the normal group, age, body mass index, seizure frequency and drug type in the abnormal group were significant differences statistically (P<0.05). The total score and energy score of QOLIE-31 in the abnormal group were significantly lower than that in the normal group (P<0.05). Binary Logistic regression analysis indicated that energy score [B=−0.033, OR=0.967, 95%CI(0.937, 0.999)], age [B=0.879, OR=2.408, 95%CI (1.070, 5.416)], seizure frequency [B=1.788, OR=5.976, 95% CI (2.031, 17.589)].ConclusionThe reproductive function of MPWE is lower than that in healthy men. The total score, energy score, age, body mass index, seizure frequency and type of drugs will significantly affect the reproductive function of MPWE. Energy score, age and seizure frequency are independent risk factors that affect the reproductive function of MPWE. Abnormal reproductive function of MPWE was positively correlated with age and seizure frequency, but negatively correlated with energy score.
