Correlation of serum androgen levels with lipid metabolism in middle-aged and elderly men in Zunyi, Guizhou / 中华男科学杂志

<p><b>Objective</b>To investigate the relationship of the levels of serum androgens with lipid metabolism in middle-aged and elderly men in Zunyi, Guizhou.</p><p><b>METHODS</b>Using the stratified cluster sampling method, we conducted a questionnaire investigation and physical examinations among 437 men in Zunyi City. We divided the subjects into a middle-aged (40－64 ［53.20 ± 7.41］ years, n = 269) and an elderly group (=≥65 ［70.63 ± 4.66］ years, n = 168) and collected fasting elbow venous blood samples from them for measuring the levels of total testosterone (TT), sex hormone-binding globulin (SHBG), luteinizing hormone (LH), total cholesterol (TCH), triglyceride (TG), high-density lipoprotein (HDL), low-density lipoprotein (LDL), calculated free testosterone (cFT), free testosterone index (FTI), and testosterone secretion index (TSI).</p><p><b>RESULTS</b>Compared with the elderly group, the middle-aged males showed significantly lower SHBG, LH, HDL and LDL, and higher cFT, FTI, TSI, TG and TCH (all P < 0.05). TT and SHBG were negatively correlated with TG, TCH, HDL and LDL, while cFT was positively correlated with TCH, and so was FTI with TG, TCH with LDL, and TSI with TCH, HDL and LDL (all P < 0.05), but LH was negatively correlated with TG, TCH and LDL (all P < 0.05). Multivariate linear regression analysis showed that TT and SHBG were negatively correlated with TG, TCH, HDL and LDL, and so was LH with TCH, HDL and LDL (all P < 0.05).</p><p><b>CONCLUSIONS</b>In the middle-aged and elderly men in Zunyi, low concentrations of TT, SHBG and LH were associated with the increased risk of high-TCH and -LDL dyslipidemia, low concentrations of TT and SHBG with that of high-TG dyslipidemia, while high concentrations of TT, SHBG and LH with that of low-HDL dyslipidemia.</p>

Vasectomy has no obvious longterm influence on the levels of serum androgens in aging males / 中华男科学杂志

Objective@#To explore the longterm influence of vasectomy on the levels of serum androgens in aging males.@*METHODS@#Using stratified random sampling, we conducted a questionnaire survey and physical examinations among 437 adult males aged ≥40 years, 232 with and 205 without the history of vasectomy. In addition, we measured the levels of serum total testosterone (TT), sexhormone binding globulin (SHBG), calculated free testosterone (cFT), testosterone secreting index (TSI), free testosterone index (FTI), and luteinizing hormone (LH).@*RESULTS@#Compared with the nonvasectomy group, the vasectomy group showed significantly increased levels of serum TT (［16.01±5.41］ vs ［17.39±6.57］ nmol/L), SHBG (［58.91±36.89］ vs ［70.28±40.90］ nmol/L), and LH (［8.86±6.49］ vs ［10.85±11.73］ IU/L) (all P0.05), nor after adjustment for relevant factors in TT (β: 1.015, 95% CI: －0.180－2.210), SHBG (β: 5.118, 95% CI: －2.069－12.305), cFT (β: 0.003, 95% CI: －0.011－0.018), FTI (β: －0.012, 95% CI: －0.035－0.011), TSI (β: 0.138, 95% CI: －0.131－0.407), and LH (β: 1.011, 95% CI: －0.811－2.834) (all P>0.05).@*CONCLUSIONS@#Vasectomy has no obvious longterm influence on the levels of serum androgens in aging males.

Effect and safety of testosterone undecanoate in the treatment of late-onset hypogonadism: a meta-analysis / 中华男科学杂志

<p><b>OBJECTIVE</b>To evaluate the efficacy and safety of testosterone undecanoate (TU) in the treatment of late-onset hypogonadism (LOH) by meta-analysis.</p><p><b>METHODS</b>We searched Pubmed (until April 1, 2014), Embase (until March 28, 2014), Cochrane Library (until April 17, 2014), CBM (from January 1, 2001 to February 2, 2014), CNKI (from January 1, 2001 to February 2, 2014), Wanfang Database (from January 1, 2000 to February 2, 2014), and VIP Database (from January 1, 2000 to Febru ary 2, 2014) for randomized controlled trials of TU for the treatment of LOH. We evaluated the quality of the identified literature and performed meta-analysis on the included studies using the Rveman5. 2 software.</p><p><b>RESULTS</b>Totally, 14 studies were included after screening, which involved 1 686 cases. Compared with the placebo and blank control groups, TU treatment significantly increased the levels of serum total testosterone (SMD = 6.22, 95% CI 3.99 to 8.45, P < 0.05) and serum free testosterone (SMD = 4.35, 95% CI 1.86 to 6. 85, P < 0.05) but decreased the contents of luteinizing hormone (WMD = -2.23, 95% CI -4.03 to -0.42, P < 0.05), sex hormone binding globulin (WMD = 2.00, 95% CI 1.38 to 2.63, P < 0.05). TU also remarkably reduced the scores of Partial Androgen Deficiency of the Aging Males (WMD = -9.49, 95% CI -12.96 to -6.03, P < 0.05) and Aging Males Symptoms rating scale (WMD = -2.76, 95% CI -4.85 to -0.66, P <0.05) but increased the hemoglobin level (SMD = 2.35, 95% CI 0.29 to 4.41, P < 0.05) and packed-cell volume (SMD = 4.35, 95% CI 1.36 to 7.33, P < 0.05). However, no significant changes were shown in aspertate aminotransferase, alanine transaminase, prostate-specific antigen, or prostate volume after TU treatment (P > 0.05).</p><p><b>CONCLUSION</b>TU could significantly increase the serum testosterone level and improve the clinical symptoms of LOH patients without inducing serious adverse reactions. However, due to the limited number and relatively low quality of the included studies, the above conclusion could be cautiously applied to clinical practice.</p>

Integrated Chinese and western medicinal treatment on systemic lupus erythematosus characterized by hypoplastic bone marrow / 中国中西医结合杂志

<p><b>OBJECTIVE</b>To study the clinical effect of combined treatment with gamma-globulin, corticosteroids, immunosuppressor and Chinese medicines on systemic lupus erythematosus (SLE) patients characterized by hypoplastic bone marrow (HBM).</p><p><b>METHODS</b>Nineteen patients were randomly assigned to two groups, the treated group (10 cases) received combined therapy of prednisone and cyclophosphamide (CTX) plus Chinese medicine Langchuang Recipe after being treated impactively with gamma-globulin. The control group (9 cases) was treated with prednisone and CTX. Changes of hypoplastic bone marrow, peripheral white blood cell (WBC), complement C3, 24 h urinary protein excretion, and lupus activity index (LAI) were observed, and a follow-up was carried out for one year.</p><p><b>RESULTS</b>After one-month treatment, the bone marrow hypoplasia was relieved significantly in the treated group (P < 0.05, P < 0.01), showing an improvement superior to that in the control group (P < 0.05, P < 0.01); after three months treatment, the level of complement C3 increased (P < 0.01), while the 24 h urinary protein excretion and LAI decreased in the treated group (P < 0.05), showing significant difference as compared with those in the control group (P < 0.05, P < 0.01). In the follow-up period, 3 cases withdrew from the trial because of infection and 4 cases manifested full moon-face and acne in the control group, while no adverse reaction was found in the treated group.</p><p><b>CONCLUSION</b>Treatment with integrated Chinese and Western medicine could effectively improve bone marrow hypoplasia, alleviate the clinical symptoms, suppress the activity of lupus in patients, and reduce the adverse reaction of treatment, showing a superiority to the treatment with prednisone combining with CTX.</p>
