Distribution of TCM syndrome types and their correlation semen parameters in infertility patients with varicocele / 中华男科学杂志

Objective@#To explore the distribution of Traditional Chinese Medicine (TCM) syndrome types and their relationship with semen parameters in infertility male patients with varicocele (VC).@*METHODS@#Using Questionnaire on Clinical Symptoms of Varicocele-Caused Male Infertility, we made an investigation among 147 infertility male patients with VC, determined the types of their TCM syndromes, obtained their semen parameters, and analyzed the distribution of the TCM syndrome types and their correlation with semen parameters.@*RESULTS@#Of the TCM syndrome types identified, kidney deficiency and stagnated heat constituted the largest proportion (34.7%), and the mixed type accounted for a significantly higher percentage than the simple type (P < 0.05). The patients with kidney deficiency and stagnated heat, compared with those with other syndrome types, had a dramatically lower sperm concentration (［21.62 ± 9.25］ vs ［28.88 ± 12.92］ ×10⁶/ml, P < 0.01), but a higher percentage of morphologically abnormal sperm (［98.33 ± 0.15］% vs ［96.27 ± 0.18］%, P < 0.05) and DNA fragmentation index (［19.72 ± 3.17］% vs ［10.96 ± 3.82］%, P < 0.01). No statistically significant differences were observed in the percentage of progressively motile sperm among different TCM syndrome types.@*CONCLUSIONS@#Kidney deficiency and stagnated heat is a main TCM syndrome type in infertility male patients with varicocele and correlated with sperm concentration, the percentage of morphologically abnormal sperm and DNA fragmentation index.

Immune mechanisms of the active ingredients of Chinese medicinal herbs for chronic prostatitis / 中华男科学杂志

Chronic prostatitis is a common male disease, and its pathogenesis is not yet clear. Most scholars believe that oxidative stress and immune imbalance are the keys to the occurrence and progression of chronic prostatitis. Currently immunotherapy of chronic prostatitis remains in the exploratory stage. This article relates the active ingredients of 5 Chinese medicinal herbs (total glucosides of paeony, tripterigium wilfordii polglycosidium, curcumin, geniposide, and quercetin) for the treatment of chronic prostatitis and their possible action mechanisms as follows: 1) inhibiting the immune response and activation and proliferation of T-cells, and adjusting the proportion of Th1/Th2 cells; 2) upregulating the expression of Treg and enhancing the patient's tolerability; 3) suppressing the activation of the NF-kB factor, reducing the release of iNOS, and further decreasing the release of NO, IL-2 and other inflammatory cytokines, which contribute to the suppression of the immune response; 4) inhibiting the production of such chemokines as MCP-1 and MIP-1α in order to reduce their induction of inflammatory response. Studies on the immune mechanisms of Chinese medicinal herbs in the treatment of chronic prostatitis are clinically valuable for the development of new drugs for this disease.

Modified Jujing No.2 Decoction for varicocele-induced male infertility / 中华男科学杂志

<p><b>Objective</b>To investigate the clinical effect of Jujing No.2 Decoction on male infertility induced by varicocele.</p><p><b>METHODS</b>We equally randomized 70 male patients with varicocele-induced infertility into a treatment group and a control group, the former treated with modified Jujing No.2 Decoction (1 dose a day, bid) and the latter given Danshen Tablets (4 tablets once, tid) plus Liu Wei Di Huang Wan (8 pills once, tid), both for 3 months. We examined the spermatic veins of the patients by ultrasonography and performed seminal analysis before and after medication.</p><p><b>RESULTS</b>Compared with the controls, the patients in the treatment group showed significant improvement after medication in sperm concentration (［12.35±2.12］ vs ［18.56±4.16］ ×10⁶/ml, P<0.05), progressively motile sperm (［16.18±6.34］ vs ［24.63±8.51］ %, P<0.05), and morphologically normal sperm (［11.59±5.31］ vs ［14.17±6.02］ %, P<0.05). In the control group, sperm concentration was increased from (12.29±2.07) ×10⁶/ml at the baseline to (13.13±3.13) ×10⁶/ml after medication, progressively motile sperm from (16.13±6.45) % to (20.55±7.30) % (P<0.05), and morphologically normal sperm from (11.62±5.35) % to (12.69±5.77) %. The total effectiveness rate was significantly higher in the treatment than in the control group (71.88% vs 46.67%, P<0.05). The inner diameter of the left spermatic vein was decreased from (0.32±0.05) mm at the baseline to ［0.26±0.05］ mm after medication in the treatment group (P<0.05) and from (0.32±0.03) mm to (0.29±0.04) mm in the control (P<0.05), with statistically significant difference between the two groups after medication (P<0.05).</p><p><b>CONCLUSIONS</b>Jujing No.2 Decoction is effective in the treatment of varicocele-induced male infertility.</p>

Therapeutic efficacy of Bushengzhuyang Fang (Yangjing Capsule) on phytoestrogen-induced erectile dysfunction: an experimental study / 中华男科学杂志

<p><b>OBJECTIVE</b>To investigate the effect of Bushengzhuyang Fang (Yangjing Capsule, YJC) on penile erectile function and its action mechanisms in rats.</p><p><b>METHODS</b>Fifty-six male SD rats were randomly divided into seven groups of equal number: blank control, daidzein, daidzein + testosterone, daidzein + sildenafil, daidzein + low-dose YJC, daidzein + medium-dose YJC, and daidzein + high-dose YJC. The rats in the blank control group were treated intragastrically with normal saline and those in the other groups with daidzein at the dose of 100 mg per kg per day for 30 days. Then the last five groups received additionally testosterone (4 mg per kg per day), sildenafil (2.5 mg per kg per day), low-dose YJC, (0.315 mg per kg per day), medium-dose YJC (0.63 mg per kg per day), and high-dose YJC (1. 26 mg per kg per day), respectively. At 0, 30 and 60 days of treatment, we observed the apomorphine-induced spontaneous erectile response and pathological changes in the corpus cavernosum of the rats, recorded the number of penile erection and erectile incubation period, and determined the serum levels of testosterone (T) and luteinizing hormone (LH).</p><p><b>RESULTS</b>At 30 days of treatment, the number of apomorphine-induced erections was decreased, the erectile incubation period prolonged, and the serum levels of T and LH reduced remarkably in all groups of rats (P < 0.05). Compared with the findings at 30 days, the number of penile erections was significantly decreased at 60 days in the daidzein group (1.39 ± 0.42 vs 2.67 ± 0.33, P < 0.05) and daidzein + low-dose YJC group (1.33 ± 0.49 vs 2.83 ± 0.61, P < 0.05); the erectile incubation period was markedly ex- tended ([16.33 ± 3.11] vs [8.50 ± 0.93] min and [15.50 ± 3.21] vs [8.63 ± 1.54] min, P < 0.05); and the serum levels of T ([5.34 ± 0.89] vs [1.24 ± 0.30] ng/ml and [5.28 ± 1.12] vs [2.07 ± 0.76] ng/ml, P < 0.05) and LH ([3.62 ± 0.37] vs [2.09 ± 0.12] ng/ml and [3.79 ± 0.28] vs [2.17 ± 0.33] ng/ml, P < 0.05) were significantly reduced in the daidzein and daidzein + low-dose YJC groups, respectively. Pathological examination revealed slightly decreased cavernous sinuses and blood vessels in the corpus cavernosum of the rats in the daidzein + testosterone, daidzein + sildenafil, daidzein + medium-dose YJC, and daidzein + high-dose YJC groups as compared with those in the blank control group.</p><p><b>CONCLUSION</b>High-dose Yangjing Capsule is efficacious for the recovery of erectile function in rats, especially for phytoestrogen-induced erectile dysfunction.</p>

Distribution, combination, and evolution of syndromic etiologies of erectile dysfunction / 中华男科学杂志

<p><b>OBJECTIVE</b>To explore the distribution, combination and evolution of various syndromic etiologies of erectile dysfunction (ED) based on the syndrome etiology theory.</p><p><b>METHODS</b>Using the ED Syndromic Etiology Scale, we collected the clinical data on the Chinese medicine diagnoses of 297 cases of ED, extracted the core syndromic etiologies by analysis of principal components and factors, and analyzed the patterns of distribution, combination, and evolution of ED syndromic etiologies according to the general information of the patients.</p><p><b>RESULTS</b>Through analysis of principal components and factors, 9 core syndromic etiologies were extracted, i. e. , liver constraint with qi stagnation, kidney yin deficiency, damp-heat, liver constraint transforming into liver-fire, blood stasis, kidney yang deficiency, heart-spleen paired deficiency, qi-yin paired deficiency, and phlegm-damp. Each of these syndrome etiologies exhibited its own specific distribution patterns. Of the total number of cases studied, 51.52% had 2 or 3 core syndromic etiologies and 36.03% had only one.</p><p><b>CONCLUSION</b>In the early stage of ED, its syndromic etiologies are usually liver constraint with qi stagnation, kidney yin deficiency, damp-heat, liver constraint transforming into liver-fire, and blood stasis. With the natural progres- sion of the disease, its syndromic etiologies gradually evolve into kidney yang deficiency, heart-spleen paired deficiency, qi-yin paired deficiency, phlegm-damp, and blood stasis, and finally into yin-yang deficiency of the heart, spleen and kidneys, combined with phlegm-damp and blood stasis.</p>

Kidney-tonifying and dampness-expelling Chinese herbal medicine combined with doxazosin for the treatment of chronic epididymitis / 中华男科学杂志

<p><b>OBJECTIVE</b>To study the clinical effects of kidney-tonifying and dampness-expelling Chinese herbal medicine combined with doxazosin in the treatment of chronic epididymitis.</p><p><b>METHODS</b>A total of 64 patients with chronic epididymitis were equally randomized into a treatment and a control group, the former treated with kidney-tonifying and dampness-expelling Chinese herbal decoction combined with doxazosin, and the latter given doxazosin only, both for 4 weeks. The clinical symptoms were measured by Chronic Epididymitis Symptom Index (CESI), Self-Rating Anxiety Scale (SAS) and Self-Rating Depression Scale (SDS) before and after the treatment, and the therapeutic effects were evaluated.</p><p><b>RESULTS</b>After 4 weeks of medication, the total mean scores on CESI, pain, and quality of life (QOL) were significantly decreased in both the treatment and the control groups (P < 0.05), even more significantly in the former than in the latter (P < 0.05), and so were the scores on SAS and SDS (P < 0.05), but with no significant differences between the two groups (P > 0.05).</p><p><b>CONCLUSION</b>Either doxazosin alone or kidney-tonifying and dampness-expelling Chinese herbal decoction combined with doxazosin is obviously effective on chronic epididymitis, but the combined medication produces an even better efficacy.</p>
