Autosomal dominant polycystic kidney disease (ADPKD) is a most common inherited renal disease, about 50% with a family history, although the exact etiology not yet clear. To date, ADPKD, a multisystem disorder without effective preventive and therapeutic means, has been shown to be detrimental to human health. Recent studies show that severe oligoasthenozoospermia, necrospermia, immotile sperm, azoospermia, epididymal cyst, seminal vesicle cyst, and ejaculatory duct cyst found in male ADPKD patients may lead to male infertility, though the specific mechanisms remain unknown. Structural anomaly of spermatozoa, defect of polycystin, mutation of PKD genes, and micro-deletion of the AZF gene could be the reasons for the higher incidence of abnormal semen quality in male ADPKD patients. Assisted reproductive techniques can increase the chances of pregnancy, whereas the health of the offspring should be taken into consideration. This article presents an overview of reproductive issues concerning infertile male ADPKD patients from the perspective of the morbidity, pathophysiological mechanism, diagnosis, and management of the disease.

OBJECTIVETo observe the efficacy of combination therapy of clomiphene and Chinese drugs for nourishing Shen and activating blood circulation (NSABC) in treating Stein-Leventhal syndrome caused sterility.
METHODSSixty-two patients with anovulation caused sterility were randomly divided into the treated group (n = 32) and the control group (n = 30). The treated grop was treated with the combination therapy and the control group treated by the same dosage of clomiphene alone.
RESULTSAfter treatment, when comparing with that before treatment, the endocrine hormones in the treated group improved significantly, showing a markedly decrease of androgen and luteotropic hormone, and increase of estrogen (P < 0.001). The periodic ovulation rate in the treated group reached 87%, the total pregnancy rate being 65.6%, with no occurrence of ovarian hyperstimulation syndrome (OHSS) and luteinized unruptured follicle syndrome (LUFS), while in the control group, the periodic ovulation rate was 66%, the total pregnancy rate 36.6%, with LUFS occurred in 4 patients. Comparison of the therapeutic effects between the two groups showed significant difference (P < 0.05).
CONCLUSIONThe combination therapy of clomiphene and NSABC has a better therapeutic effect in treating Stein-Leventhal syndrome caused sterility than that of using clomiphene alone.

OBJECTIVETo evaluate the therapeutic effect of Longjintonglin Capsules on type IIIA prostatitis accompanied by abnormal semen liquefaction.
METHODSWe selected 140 patients with type IIIA prostatitis accompanied by abnormal semen liquefaction according to the diagnostic standards of the American Institutes of Health (NIH) and treated them with Longjintonglin Capsules orally 3 capsules once tid for 12 weeks. We obtained the NIH Chronic Prostatitis Symptom Indexes (NIH-CPSI), traditional Chinese medicine (TCM) syndrome scores, leukocyte count in the expressed prostatic secretion (EPS), semen liquefaction time, and the results of semen analysis and compared these indicators before and after the treatment.
RESULTSOf the 140 cases, 132 were included in this study, excluding 8 due to their incomplete case histories. Before and after 4, 8 and 12 weeks of medication, the total NIH-CPSI scores were 24.52 ± 5.43, 21.28 ± 4.85, 18.01 ± 4.28, and 14.49 ± 3.65 (P < 0.01), the TCM syndrome scores were 35.63 ± 6.07, 26.66 ± 5.03, 17.37 ± 4.18, and 11.11 ± 3.96 (P < 0.01), and the leukocyte counts (/HP) were 27.50 ± 7.01, 22.38 ± 5.22, 16:76 ± 4.10, and 11.40 ± 4.74 (P < 0.01), respectively. After 12 weeks of treatment, 31 of the patients with type IIIA prostatitis were cured and another 72 well responded, with an overall response rate of 78.0%. Of those with abnormal semen liquefaction, 61 were cured, 39 well responded, and 32 failed to respond, with an overall effectiveness rate of 75.8%. Semen analysis showed significantly increased percentage of progressively motile sperm after 4, 8 and 12 weeks of medication as compared with the baseline (P < 0.01). No abnormal liver or renal function or other adverse reactions were observed during the treatment.
CONCLUSIONLongjintonglin Capsules, with its advantages of safety, effectiveness and no obvious adverse effects, deserve to be recommended for the treatment of type IIIA prostatitis accompanied by abnormal semen liquefaction.

In this study, plate transparent circle by Davis method was introduce firstly screening ?-Rhamnosidase high-yield strain. The spore-sprouted Aspergillus niger 8-hour were mutagenized by ethyl methane sulphonate and pre-screened via transparent circle. 11% mutants yield 40% higher of ?-rhamnosidase than the original strain. A high-yield strain, T-226 with the highest ?-rhamnosidase activity of 373.4 U/mL was finally selected from these potential high-yield mutants after rescreened by shake flask fermentation twice. When the T-226 strain was fermented in 5 L bioreactor, the enzyme activity could reach to 631.9 U/mL after 84 h. Thus, the established screening method is highly efficient to isolate ?-rhamnosidase high-yield mutant of A. niger.

?AIM:To evaluate the objective visual quality of patients who underwent corneal cross-linking for the keratoconus using double-pass analysis system.? METHODS: Advanced keratoconus patients who underwent UV - riboflavin corneal cross - linking from January to July 2015 were included. The outcomes of their objective scattering index ( OSI ) , predicted visual acuity ( VA ) , the cut - off frequency of modulation transfer function ( MTF cut- off ) , the Strehl ratio ( SR ) were compared before and 6mo after corneal cross-linking.?RESULTS: A total of 13 patients ( 16 eyes ) were included. There was no statistically significant difference between pre- and 6mo postoperative data in uncorrected visual acuity, best corrected visual acuity, refractions and mean value of Sim-k (P>0. 05). Non-invasive average tear film break up time ( NIAvg-BUT ) detected by the Sirius system decreased after corneal cross-linking ( P<0. 05 ) . Using double - pass analysis system, no statistically significant change was found in MTF cut off, Strehl Ratio, OSI before and after treatment(P>0. 05). Tear Film Analysis Mean OSI increased at 6mo postoperatively (P<0. 05).? CONCLUSION: The subjective visual quality isn’t effected by corneal cross-linking. The tear stabilities of patients are influenced by these operations at 6mo postoperatively. More observations on long-term effect are needed to be taken in the future.
