[Tonglong Kaibi Prescription for the treatment of severe benign prostate hyperplasia: A clinical study].

OBJECTIVE: To evaluate the clinical effect of the traditional Chinese medicine (TCM) Tonglong Kaibi Prescription (TKP) in the treatment of severe BPH with kidney deficiency and blood stasis combined with damp heat syndrome. METHODS: We randomly divided 120 cases of severe BPH with kidney deficiency and blood stasis combined with damp heat syndrome into three groups of equal number, treated with TKP, doxazosin mesylate sustained-release tablets (the DM control), and TKP + DM, all for 8 weeks. We obtained the IPSS, TCM symptoms scores, quality of life (QOL) scores, maximum urinary flow rate (Qmax) and postvoid residual urine volume (PVR) from the patients before and after treatment and compared them among the three groups. RESULTS: After 8 weeks of treatment, the effectiveness rate was significantly higher in the TKP + DM than in the DM control group (P < 0.05). The IPSS, TCM symptoms scores, QOL scores and PVR decreased (P < 0.01), while the Qmax increased dramatically (P < 0.01) in all the three groups. Pairwise comparison showed that the IPSS and QOL scores were lower in the TKP + DM than in the TKP and DM control groups (P < 0.05 or 0.01), and so were the TCM syndrome scores in the TKP + DM and TKP groups than in the DM control (P < 0.01). There were no statistically significant differences in PVR and Qmax among the three groups after treatment (P> 0.05), and no serious adverse events during the treatment. CONCLUSION: TKP is safe and effective in the treatment of severe BPH, which can improve the TCM symptoms, reduce the IPSS, QOL scores and PVR and increase the Qmax of the patients. TKP is evidently superior to DM alone in improving TCM symptoms of BPH and combined medication of TKP and DM produces even better clinical efficacy.

[Research progress on the establishment and application of the hypoxia cell model in varicocele-associated male infertility].

Varicocele (VC) is considered as one of the primary causes of male infertility, and the pathogenesis and treatment measures for VC-associated male infertility (VMI) are being explored continuously. The construction of an appropriate in vitro model for VMI is of significant importance for the study of this disease. And the model of testis cell hypoxia, with its relatively stable experimental conditions, short cycle, good repeatability and few influencing factors, has been primarily applied in cellular experimental researches on VMI. This article reviews the selection of cell lines, use of modeling methods, and evaluation of cell models in recent VMI-related cellular experiments, aiming to provide some reference for scholars in their studies of the pathogenesis and treatment of VMI using the in vitro experimental model.

[Pricking-reinforcing -reducing therapy improves semen quality and seminal plasma biochemical indexes in patients with varicocele infertility].

OBJECTIVE: To investigate the effect of pricking-reinforcing -reducing therapy (PRRT) on the semen quality and seminal plasma biochemical indexes of varicocele (VC) infertility patients. METHODS: We randomly and equally assigned 160 patients with VC infertility into a PRRT and a control group, the former treated by PRRT and the latter with oral ShengjingCapsules. Before and after treatment, we obtained the semen parameters, sperm morphology, sperm survival rate, sperm acrosin activity, seminal plasma neutral α glucosidase and seminal plasma zinc in the patients and compared them between the two groups. RESULTS: Before treatment, there were no statistically significant differences between the PRRT and control groups in sperm concentration (ï¼»16.81 ± 7.83ï¼½ vs ï¼»16.80 ± 7.54ï¼½ ×106 /ml, P > 0.05), total sperm count (ï¼»42.01 ± 19.57ï¼½ vs ï¼»41.99 ± 18.84ï¼½ ×106, P > 0.05), percentages of progressively motile sperm (PMS) (ï¼»15.37 ± 11.03ï¼½% vs ï¼»14.68 ± 10.27ï¼½%, P > 0.05) and morphologically normal sperm ( MNS) (1.62 ± 1.51ï¼½% vs ï¼»1.62 ± 1.13ï¼½%, P > 0.05), sperm survival rate (ï¼»28.11 ± 18.95ï¼½% vs ï¼»28.23±18.38ï¼½%, P > 0.05) and sperm acrosin activity (ï¼»28.11 ± 14.64ï¼½ vs ï¼»27.19 ± 14.07ï¼½ U/L, P > 0.05). After three months of treatment, all the patients showed evident increases in the above parameters (P < 0.05), even higher in the PRRT than in the control group, more significantly in sperm concentration (ï¼»38.88 ± 30.54ï¼½ vs ï¼»25.60 ± 14.71ï¼½ ×106 /ml, P < 0.05), PMS (ï¼»32.60 ± 12.46ï¼½% vs ï¼»27.67 ± 12.27ï¼½%, P < 0.05) and sperm acrosin activity (ï¼»65.74±31.81ï¼½ vs ï¼»67.94±17.95ï¼½ U/L, P < 0.05), though not significantly in total sperm count (97.20 ± 76.35ï¼½ vs ï¼»88.19 ± 39.56ï¼½ ×106, P > 0.05), MNS (ï¼»2.35 ± 1.83ï¼½% vs ï¼»1.87 ± 1.20ï¼½%, P > 0.05) and sperm survival rate (ï¼»61.44 ± 20.02ï¼½% vs ï¼»59.12 ± 22.48ï¼½%, P > 0.05). Compared with the baseline, after treatment, the patients in the PRRT group also exhibited elevated levels of neutral α-glucosidase (ï¼»14.42 ± 5.90ï¼½ vs ï¼»28.43 ± 19.76ï¼½ U/L, P < 0.05) and seminal plasma zinc (ï¼»2.11 ± 1.22ï¼½ vs ï¼»2.89 ± 1.23ï¼½ mmol/L, P < 0.05), and so did the controls (ï¼»14.44 ± 5.61ï¼½ vs ï¼»26.66 ± 17.69ï¼½ U/L , P < 0.05) and (ï¼»2.09 ± 1.10ï¼½ vs ï¼»2.82±1.08ï¼½ mmol/L, P < 0.05). No statistically significant difference, however, was observed between the two groups after treatment (P > 0.05). CONCLUSION: PRRT can significantly improve semen quality in patients with VC infertility, even more effective than ShengjingCapsules in improving sperm concentration, PMS, sperm survival rate, and sperm acrosin activity, which may be related to its effect of elevating the levels of seminal plasma neutral-α glucosidase and zinc providing sufficient energy for basic sperm metabolism, maturation, energy acquisition and motility.

[Danhong Tongjing Prescription versus microsurgery in the treatment of varicocele-induced infertility: A retrospective multivariate analysis of 218 cases].

OBJECTIVE: To compared the traditional Chinese medicine Danhong Tongjing Prescription (DTP) and microsurgery in the treatment of varicocele (VC)-induced infertility and investigate the factors influencing the recovery of semen parameters of the patients. METHODS: We retrospectively analyzed the clinical data on 218 cases of VC-induced infertility with qi-deficiency and blood-stasis treated with DTP (n = 86) or by microsurgery (n = 132) in our hospital from January 2017 to July 2019, and compared the semen parameters between the two groups of patients after treatment. With age, course of disease, degree of VC, change of the testis volume, estrogen/testosterone (E/T) ratio and levels of FSH and LH as independent variables, and increased semen parameters after treatment as dependent variables, we constructed a multivariate linear regression model and identified statistically significant independent variables. RESULTS: After treatment, sperm concentration and the percentages of progressively motile sperm (PMS) and morphologically normal sperm (MNS) were obviously improved in both the DTP and microsurgery groups, with statistically significant difference between the two groups in sperm concentration and MNS, but not in PMS. Linear regression analysis showed that the severity of VC was an influencing factor for the recovery of sperm concentration after treatment in the DTP group (r = －11.599, Ra2 = 0.044 9) and the course of VC infertility was a factor affecting the recovery of sperm count in the microsurgery group (r = －1.837, Ra2 = 0.035 7). CONCLUSION: DTP is comparable to microsurgery in improving sperm motility while microsurgery is more effective in increasing the percentage of MNS in the treatment of VC-induced infertility. Early surgery is recommended for the treatment of infertility induced by severe bilateral VC, and DTP can be selected for infertility caused by mild or moderate bilateral VC if the patient is unwilling to accept surgery or microsurgery is inaccessible in the hospital.

[Magnetic resonance and magnetoelectric therapy combined with Danhong Tongjing Prescription for the treatment of CP/CPPS and its effects on secretory IgA, vascular cell adhesion molecule-1 and interleukin-8].

OBJECTIVE: To investigate the therapeutic effect of magnetic resonance and magnetoelectric therapy (MRMT) combined with oral Danhong Tongjing Prescription (DTP) on chronic prostatitis / chronic pelvic pain syndrome (CP/CPPS) and the changes in the levels of cytokine-secretory IgA (sIgA), vascular cell adhesion molecule-1 (VCAM-1) and interleukin-8 (IL-8) after treatment. METHODS: Totally 200 patients with CP/CPPS of the qi stagnation and blood stasis type were randomly divided into three groups to receive MRMT + DTP (n = 68), MRMT (n = 67) and DTP (n = 65), respectively, all for 12 weeks. After treatment, we compared the total effectiveness rate, patients' scores on NIH-CPSI and traditional Chinese medicine (TCM) syndrome, and the expressions of sIgA, VCAM-1 and IL-8 in the EPS among the three groups of the patients. RESULTS: After treatment, the patients in the MRMT + DTP group, compared with those in the MRMT and DTP groups, showed a significantly higher total effectiveness rate (86.76% vs 79.10% and 78.46%, P < 0.05 and P < 0.01) and lower scores on pain or discomfort (4.61 ± 2.37 vs 5.86 ± 3.26 and 6.94 ± 2.25 P < 0.01), abnormal urination symptoms (2.98 ± 1.75 vs 3.85 ± 2.01 and 3.94 ± 1.95) and quality of life (3.26 ± 1.87 vs 4.54 ± 2.13 and 4.69 ± 1.72). There were statistically significant differences in the total NIH-CPSI scores among the three groups (10.64 ± 5.91 vs 4.59 ± 6.87 vs 15.54 ± 5.76, P < 0.05). The MRMT + DTP group also exhibited a remarkably lower TCM syndrome score than the MRMT and DTP groups (5.56 ± 3.42 vs 7.37 ± 4.57 and 8.16 ± 3.65, P < 0.05). Compared with the baseline, the expressions sIgA, VCAM-1 and IL8 were all markedly decreased after treatment in the MRMT + DTP (Z = －7.170, Z = －7.182, Z = －7.18), MRMT (Z = －6.802, Z = －6.973, Z = －6.768) and DTP groups (Z = －5.963, Z = －6.990 Z = －5.618) (P < 0.05), even more significantly in the former than in the latter two groups (P < 0.05). CONCLUSION: Magnetic resonance and magnetoelectric therapy combined with Danhong Tongjing Prescription has a good therapeutic effect on CP/CPPS of the qi stagnation and blood stasis type, probably by regulating sIgA, VCAM-1, IL-8 and other cytokines, activating the function of the immune system, inhibiting inflammation, and promoting the absorption of local inflammatory substances.

[Danhong Tongjing Prescription improves sperm quality in patients with bilateral varicocele after varicocelectomy].

OBJECTIVE: To investigate the effect of Danhong Tongjing Prescription (DTP) on sperm quality in patients with bilateral varicocele (VC) after microsurgical varicocelectomy. METHODS: We randomly assigned 68 patients with bilateral VC to receive microsurgical varicocelectomy (the control group, n = 34) or microsurgical varicocelectomy followed by oral administration of DTP for a course of 90 days (the DTP group, n = 34). Before and after treatment, we obtained the sperm concentration, total sperm count, total sperm motility, the percentage of progressively motile sperm (PMS), sperm acrosomal enzyme activity, inhibin B (Inh-B) level, and sperm DNA fragmentation index (DFI) from the patients and compared the parameters between the two groups. RESULTS: There were no statistically significant differences in sperm concentration, PMS, acrosomal enzyme activity or sperm DFI among the patients with different degrees of VC preoperatively. After 3 months of medication, sperm concentration, total sperm count, total sperm motility, PMS and acrosomal enzyme activity were all increased while DFI decreased in both the control and DTP groups, even more significantly in the DTP group than in the control, and the Inh-B level was also markedly elevated in the DTP group in comparison with the baseline. CONCLUSIONS: The severity of bilateral VC is not correlated with the reduction of semen quality. DTP can improve sperm quality by improving total sperm count, PMS and acrosomal enzyme activity and reducing DFI in VC patients after varicocelectomy. The underlying mechanisms of the prescription may be related to its anti-oxidative stress action and abilities of improving reproductive hypoxia, spermatogenic environment and the function of Sertoli cells, but the specific signaling pathway involved is not yet clear.

[Lingze Tablets for BPH with kidney-deficiency, blood stasis and dampness resistance: A phase-â £ open-label single-arm multicenter clinical study and safety evaluation].

OBJECTIVE: To evaluate the efficacy and safety of Lingze Tablets in the treatment of BPH with kidney deficiency, blood stasis and dampness resistance. METHODS: Totally 235 eligible BPH patients, aged 50－80 years and meeting the inclusion criteria, were enrolled and treated with Lingze Tablets orally, 4 tablets per time, tid. Before and after an 8-week course of medication, IPSS, quality of life (QOL) and TCM syndromes scores were obtained from the patients. RESULTS: Of the total number of patients, 211 completed the whole course of treatment. Compared with the baseline, the IPSS was dramatically reduced after 4 and 8 weeks of medication (18.28 ± 5.29 vs 12.82 ± 4.66 and 9.23 ± 4.21, P < 0.01), and so were the QOL scores (6.44 ± 1.99 vs 4.95 ± 1.64 and 3.16 ± 1.53, P < 0.01) and TCM syndromes scores (17.49 ± 5.30 vs 12.45 ± 3.74 and 9.17 ± 3.24, P < 0.01). The incidence rates of adverse events and drug-related adverse reactions were 15.2% and 1.9%, respectively, and no organ function impairment was observed. CONCLUSIONS: Lingze Tablets are definitely effective and safe for the treatment of BPH with kidney deficiency, blood stasis and dampness resistance.

[Acupuncture for chronic pelvic pain syndromes (CPPS) and its effect on cytokines in prostatic fluid].

OBJECTIVE: To explore the effect of acupuncture on chronic pelvic pain syndromes (CPPS), and its therapeutic mechanism. METHODS: Fourty-seven cases of CPPS were treated with electroacupuncture on Zhongji (CV 3), Guilai (ST 29), Yinlingquan (SP 9), Sanyinjiao (SP 6), Guanyuan (CV 4), Shuidao(ST 28), Xuehai (SP 10) and Taichong (LR 3) as main acupoints. Chronic Prostatitis Symptom Index (CPSI) was adopted to grade the severity of pain or discomforts. Additionally, the levels of Interleukin-8 (IL-8), Interleukin-10 (IL-10) and Tumor necrosis factor-alpha (TNF-alpha) in prostate fluid were detected and the correlation between those changes and pain score was analyzed. RESULTS: After treatment, pain or discomfort score in CPSI decreased remarkably as compared with that before treatment (P < 0.01). The levels of IL-8, IL-10 and TNF-alpha were lower than those before treatment (P < 0.01, P < 0.05). The positive correlation was obtained between IL-10 level and pain score (P < 0.05). The total effective rate was 89.4% (42/47). CONCLUSION: Acupuncture has significant efficacy on CPPS through reducing IL-10 level to ease pain, and reducing the levels of IL-8 and TNF-alpha to relieve inflammatory reaction.

[Acupoint-injection of BCG polysaccharide nuclear acid for treatment of condyloma acuminatum and its immunoregulatory action on the patient].

OBJECTIVE: To probe into immunological mechanisms and clinical therapeutic effect of acupoint-injection of BCG polysaccharide nuclear acid (BCG-PSN) for treatment of condyloma acuminatum (CA). METHODS: Two hundred cases were randomly divided into 4 groups. After removed the CA by laser, the treatment group (group A) was treated with acupoint-injection of BCG-PSN, the control group I (group B) with intramuscular injection of BCG-PSN, the control group II (group C) with intramuscular injection of interferon, and the blank control group (group D) with no treatment. The levels of cellular immune function were detected before treatment and after treatment of 6 months, and the cases of relapse were recorded. RESULTS: The cured rate of 94.3% in the group A was significantly higher than 78.0% in the group B, 80.4% in the group C and 78.2% in the group D, with significant differences (P < 0.05); in the group A, CD4+ percent increased, CD8+ percent decreased, CD4+ /CD+ ratio increased, and NK cell activity increased with a low relapse rate, and with significant differences as compared with the control groups (P < 0.05, P < 0.01). CONCLUSION: Acupoint-injection of BCG-PSN has a better therapeutic effect and it can obviously reduce the recurrence rate of CA. The cellular immunoregulatory action is one of the mechanisms of this therapy in preventing relapse of CA.
