[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.

[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.

[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.

[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.

[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.

[Lingze Tablets for BPH with kidney-deficiency, blood stasis and dampness resistance: A phase-Ⅳ 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.

[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.

[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.

[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.
