[Sperm-hyaluronan binding assay in in vitro fertilization and embryo transfer].

Objective: To explore the application value of sperm-hyaluronan binding (SHB) assay in in vitro fertilization and embryo transfer (IVF-ET).

Methods: This retrospective study included 163 cases of IVF-ET performed in our hospital from January to August 2019 due to female fallopian tube abnormality-induced infertility. The men were found with normal seminal parameters at semen analysis.

[Effects of Yishen Shengjing Capsules on semen quality and gonadal hormone levels in rats with dibutyl phthalate-induced reproductive function injury].

Objective: To study the possible pathogenesis of infertility caused by dibutyl phthalate (DBP) and investigate the effects of Yishen Shengjing Capsules (YSC, kidney-tonifying and essence-producing capsules) on DBP-induced reproductive function injury and its possible action mechanisms in male Wistar rats.

Methods: Models of DBP-induced reproductive function injury were made in 80 male Wistar rats and another 20 were used as blank controls. After modeling, the model rats were randomly divided into a model control, a high-dose YSC, a medium-dose YSC, and a low-dose YSC group.

[Inhibitory effect of Qiangjing Tablets on the Fas/FasL pathway of cell apoptosis in male SD rats with infertility].

Objective: To observe the effects of Qiangjing Tablets (QJT) on the semen quality and Fas/FasL signaling pathway in male SD rats with infertility.

Methods: Models of infertility were made in 50 male SD rats by intragastric administration of Tripterygium (GTW) for 3 weeks, and another 20 rats were taken as blank controls. Then 40 successfully established rat models were randomly divided into four groups, model control, low-dose QJT, medium-dose QJT, and high-dose QJT, the latter three groups treated intragastrically with QJT at 58 mg, 105 mg, and 233 mg per kg of the body weight per day, respectively.

Correlation study between the polymorphism of repetitive sequence in gene CAG of androgen receptor and the occurrence and progression of prostate cancer.

Objective: To explore the relation between the polymorphism of repetitive sequence in gene CAG of androgen receptor (AR) and the susceptibility and clinical stages as well as pathological grading of prostate cancer among Han population.

Method: Sixty-eight cases with prostate cancer hospitalized in Urinary Surgery Department from Feb. 2010 to Feb.

[Effects of Qiangjing Capsule on the oxidative and antioxidative system in the epididymis of varicocele rats].

Objective: To observe the effects of Qiangjing Capsule (QC) on the oxidative amd antioxidative system in the epididymis of varicocele rats in comparison with those of Shaofuzhuyu Capsule (SC) and Wuziyanzong Capsule (WC), and to explore its possible mechanism of enhancing epididymal sperm maturation.

Methods: Ten of 100 adolescent male SD rats were randomized to a sham-operation group, and varicocele models were successfully established in 72 of the other 90 by narrowing of the left renal vein. Then the model rats were equally assigned to 6 groups: model control, high-dose QC (0.

[Modified Bazhengsan for urination symptoms of chronic prostatis with damp-heat accumulated in the lower jiao].

Objective: To study the clinical effects of the modified formula of Bazhengsan on the urination symptoms of chronic prostatis with damp-heat accumulated in the lower jiao.

Methods: A total of 72 chronic prostatitis patients with damp-heat accumulated in the lower jiao were equally randomized to receive the modified formula of Bazhengsan (the trial group) and the primal Bazhengsan (the control group), both for a course of 28 days. Then we observed the changes in the NIH-CPSI scores, scores on Traditional Chinese Medicine (TCM) syndrome, maximum flow rate of urine (MFR) and results of the expressed prostatic secretion test (EPS).

[Xiaojin Wan inhibits the expression of COX-2 in prostate tissues of prostatitis pain rats].

Objective: To study the effect of Xiaojin Wan on the expression of COX-2 in the prostate tissues of rats with prostatitis pain, and the action mechanism of the drug alleviating the prostatitis pain.

Methods: Sixty male Wistar rats were randomized into two groups, 10 as blank controls, injected with aqua pro injection into the ventral part of prostate, and the other 50 as prostatitis pain models, given complete Freund's adjuvant (CFA). Three days later, the pain model rats were again equally divided into 5 subgroups: model control, Celecoxib Capsules, high-, median- and low-dose Xiaojin Wan, receiving intragastric administration of distilled water, Celecoxib Capsules and different doses of Xiaojin Wan respectively for 4 weeks.
