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 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.

OBJECTIVETo evaluate the effect and safety of L-carnitine in the treatment of idiopathic oligoasthenozoospermia based on current clinical evidence.

METHODSWe searched the Cochrane Library, PubMed, MEDLINE, EMBASE, CNKI, VIP, CBM and Wanfang Database from the establishment to April 2014 for the published literature on the treatment of idiopathic oligoasthenozoospermia with L-carnitine. We conducted literature screening, data extraction, and assessment of the methodological quality of the included trials according to the inclusion and exclusion criteria, followed by statistical analysis with the RevMan 5. 2 software.

RESULTSSeven randomized controlled trials involving 751 patients with idiopathic oligoasthenozoospermia met the inclusion criteria, and 678 of them were included in the meta-analysis. L-carnitine treatment achieved a significantly increased rate of spontaneous pregnancy as compared with the control group (RR = 3.2, 95% CI 1.74 to 5.87, P = 0.0002). After 12-16 and 24-26 weeks of medication, total sperm motility (WMD = 5.21, 95% CI 2.78 to 7.64, P < 0.0001 and WMD = 9.29, 95% CI 1.28 to 17.29, P = 0.02) and the percentage of progressively motile sperm (WMD = 12.44, 95% CI 4.58 to 20.31, P = 0.002 and WMD = 9.76, 95% CI 3.56 to 15.97, P = 0.002) were remarkably higher than those in the control group, but no statistically significant differences were observed in sperm concentration between the two groups (WMD = 4.91, 95% CI -2.63 to 12.45, P = 0.2 and WMD = 0.93, 95% CI -3.48 to 5.34, P = 0.68). After 12-16 weeks of treatment, the percentage of morphologically abnormal sperm was markedly decreased in the L-carnitine group as compared with the control (WMD = -2.48, 95% CI -4.35 to -0.61, P = 0.009), but showed no significant difference from the latter group after 24-26 weeks (WMD = -4.38, 95% CI -9.66 to 0.89, P = 0.1). No statistically significant difference was found in the semen volume between the two groups after 12-16 or 24-26 weeks of medication (WMD = -0.13, 95% CI -0.43 to 0.18, P = 0.42 and WMD = 0.28, 95% CI -0.02 to 0.58, P = 0.07). No serious L-carnitine-related adverse events were reported in 4 of the randomniized controlled trials.

CONCLUSIONThe current evidence indicates that L-carnitine can improve spontaneous pregnancy and semen parameters in the treatment of idiopathic oligoasthenozoospermia, with no serious adverse reactions.

OBJECTIVETo investigate the method and results of disk reposition in the treatment of traumatogenic TMJ ankylosis.

METHODSIn 19 cases of traumatogenic ankylosis of TMJ, the dislocated disks were repositioned during anthroplasty. In the operation, the dissection of dislocated disk was performed carefully around the TMJ. The disk was repositioned to its anatomic location over the top of condylar stump, then the lateral aspect of the disk was sutured to the soft tissue of zygomatic root.

RESULTSAt the last follow-up examination, interincisal opening distance ranged from 24 to 43 mm in all cases (mean 32.63 mm), which approached or reached the normal level. No recurrence and TMJ symptom were found during the period of follow-up.

CONCLUSIONSThe disk repositioning in treatment of traumatogenic TMJ ankylosis is a feasible and effective approach to reconstruct the structure and function and prevent recurrence.
