Abstract
OBJECTIVE To evaluate the effect of L-carnitine (LC) on low sperm acrosin activity in infertile man. METHODS A total of 240 male infertility patients with low sperm acrosin activity were randomly assigned to an LC group (n = 180) and a control group (n = 60) to be treated with LC (1g, tid) and vitamin E (VE) capsules (100 mg, tid) respectively, both for 3 months. Based on the results of routine semen analysis, the patients in the experimental group were further divided into oligozoospermia, asthenozoospermia and normozoospermia subgroups. Semen parameters and sperm acrosin activity were examined before and after treatment. RESULTS Totally, 220 of the patients completed the treatment and follow-up, 163 in the LC medication and 57 in the VE control group. Compared with the baseline, the percentage of progressively motile sperm (PMS) was significantly increased in the LC group after 3 months of treatment ([32.58 ± 1.13]% vs [36.35 ± 1.26]%, P < 0.05), and so was sperm acrosin activity ([37.05±0.66] vs [58.61±1.93] μIU/106 sperm, P < 0.01). Sperm concentration, PMS and sperm acrosin activity were also improved in the VE control group after treatment, but with no statistically significant difference (P > 0.05). In comparison with pretreatment, remarkable increases were observed after LC medication in sperm concentration in the oligozoospermia subgroup ([11.27 ± 0.73] vs [21.82 ± 4.21] ×10⁶/ml, P < 0.01) and PMS in the asthenozoospermia patients ([20.61 ± 0.85]% vs [29.81 ± 1.88]%, P < 0.01). And sperm acrosin activity was even higher after treatment in the asthenozoospermia than in the oligozoospermia and normozoospermia subgroups ([60.85 ± 3.04] vs [56.32 ± 2.86] and [57.09 ± 6.31] μIU/106 sperm, P < 0.05). CONCLUSIONS L-carnitine can effectively elevate sperm acrosin activity in male infertility patients, particularly in those with asthenozoospermia.

Abstract
OBJECTIVE To study the protective effect of lipoic acid (LA) on the spermatogenic function of the male rats with oligoasthenozoospermia induced by ornidazole (ORN). METHODS Seventy male SD rats were equally randomized into groups A (solvent control: 1 ml 0.5% CMC-Na + 1 ml olive oil), B (low-dose ORN model: 400 mg/kg ORN suspension + 1 ml olive oil), C (low-dose ORN + low-dose LA treatment: 400 mg/kg ORN + 50 mg/kg LA), D (low-dose ORN + high-dose LA treatment: 400 mg/kg ORN + 100 mg/kg LA), E (high-dose ORN model: 800 mg/kg ORN suspension + 1 ml olive oil), F (high-dose ORN + low-dose LA treatment: 800 mg/kg ORN + 50 mg/kg LA), and G (high-dose ORN + high-dose LA treatment: 800 mg/kg ORN + 100 mg/kg LA), and treated respectively for 20 successive days. Then all the rats were sacrificed and the weights of the body, testis, epididymis and seminal vesicle obtained, followed by calculation of the organ index, determination of epididymal sperm concentration and motility, and observation of the histomorphological changes in the testis and epididymis by HE staining. RESULTS Compared with group A, group E showed significantly decreased body weight ([117.67 ± 11.53] vs [88.11 ± 12.65] g, P < 0.01) and indexes of the testis ([1.06 ± 0.12] vs [0.65 ± 0.13] %, P < 0.01) and epididymis ([0.21 ± 0.03] vs [0.17 ± 0.01] %, P < 0.01). In comparison with group E, group F exhibited remarkable increases in the epididymal index ([0.17 ± 0.01] vs [0.20 ± 0.02] %, P < 0.01), and so did group G in the body weight ([88.11 ± 12.65] vs [102.70 ± 16.10] g, P < 0.05) and the indexes of the testis ([0.65 ± 0.13] vs [0.95 ± 0.06] %, P < 0.01) and epididymis ([0.17 ± 0.01] vs [0.19 ± 0.02] %, P < 0.05), but no obvious difference was observed in the index of seminal vesicle among different groups. Compared with group A, group B manifested significant decreases in sperm motility ([74.12 ± 8.73] vs [40.25 ± 6.08] %, P < 0.01), and so did group E in sperm count ([38.59 ± 6.40] vs [18.67 ± 4.59] ×105/100 mg, P < 0.01) and sperm motility ([74.12 ± 8.73] vs [27.58 ± 8.43] %, P < 0.01). Sperm motility was significantly lower in group B than in C and D ([40.25 ± 6.08] vs [58.13 ± 7.62] and [76.04 ± 8.44]%, P < 0.01), and so were sperm count and motility in group E than in F and G ([18.67 ± 4.59] vs [25.63 ± 9.66] and [29.92 ± 4.15] ×105/100 mg, P < 0.05 and P < 0.01; [27.58 ± 8.43] vs [36.56 ± 11.08] and [45.05 ± 9.59] %, P < 0.05 and P < 0.01). There were no obvious changes in the histomorphology of the testis and epididymis in groups A, B, C and D. Compared with group A, group E showed necrotic and exfoliated spermatogenic cells with unclear layers and disorderly arrangement in the seminiferous tubules and remarkably reduced sperm count with lots of noncellular components in the epididymal cavity, while groups F and G exhibited increased sperm count in the seminiferous tubules and epididymis lumen, also with exfoliation, unclear layers and disorderly arrangement of spermatogenic cells, but significantly better than in group E. CONCLUSIONS LA can reduce ORN-induced damage to the spermatogenetic function of rats, improve sperm quality, and protect the reproductive system.

Abstract
OBJECTIVE To explore Mycoplasma genitalium (MG) infection in the urogenital tract of infertile men and its influence on semen quality. METHODS Semen samples were collected from 352 infertile males in the Center of Reproductive Medicine of Nanjing General Hospital from March to July 2015. MG infection was detected by real-time fluorescence simultaneous amplification and testing and semen analyses were conducted according to the WHO Laboratory Manual for the Examination and Processing of Human Semen (5th Ed) on the semen pH value, semen volume, total sperm count, sperm concentration, total sperm motility, percentages of progressively motile sperm (PMS) and immotile sperm (IMS), and sperm DNA fragmentation index (DFI). The data obtained were subjected to statistical analysis by t-test and non-parametric test (Wilcoxon test). RESULTS MG infection was found in 3.4% (12/352) of the infertile patients. Compared with the MG-positive cases, the MG-negative ones showed a significantly higher semen volume ([2.85 ± 0.14] vs [3.84 ± 0.12] ml, P = 0.008) and percentage of PMS ([15.86±1.72] vs [60.95 ± 5.63] %, P = 0.032) but a lower DFI ([30.73 ±2.24] vs [20.71 ± 1.55]%, P = 0.014). However, no statistically significant differences were observed between the two groups in the semen pH value (7.38 ±0.02 vs 7.39 ± 0.01, P = 0.774), sperm concentration ([52.96 ± 15.78] vs [60.05 ± 4.29]×10⁶/ml, P = 0.683), sperm count ([154.15 ± 46.37] vs [221.56 ± 15.43]×106, P = 0.236), total sperm motility ([29.04 ± 3.11] vs [33.52 ± 1.51] %, P = 0.626), or percentage of IMS ([23.57 ± 0.99] vs [62.34 ± 1.69] %, P = 0.691). CONCLUSIONS Urogenital MG infection is common in infertile males and potentially affects the semen quality, especially sperm vitality of the patient.

Abstract
Objective: To investigate the molecular markers of copy number aberrations (CNAs) of genes related to extrohepatic metastasis-free survival after the operation for hepatocellular carcinoma (HCC). Methods: The CNA status of 20 candidate genes in 66 HCC samples was detected by microarray comparative genomic hybridization. The associations between gene CNAs and extrohepatic metastasis-free survival were evaluated using the Cox regression model, Log-rank test, and Kaplan-Meier survival analysis. Results: Multivariate Cox analysis revealed that the independent risk factors for metastasis-free survival were MDM4 gain (hazard ratio [HR] = 2.74, 95% confidence interval [CI] = 1.18-6.37, P < 0.05), APC loss (HR = 8.43, 95% CI = 2.48-28.66, P < 0.01), and BCL2L1 gain (HR = 3.45, 95% CI = 1.13-10.52, P < 0.05) and the independent protective factor was FBXW7 loss (HR = 0.32, 95% CI = 0.12-0.89, P < 0.05). By stepwise Cox regression analysis, three CNAs related to metastasis-free survival were screened out: MDM4 gain (HR = 2.71, 95% CI = 1.11-6.64, P < 0.05), APC loss (HR = 7.19, 95% CI = 1.88-27.60, P < 0.005), and FBXW7 loss (HR = 0.16, 95% CI = 0.05-0.46, P < 0.01). There were significant differences in metastasis-free survival rate between the HCC patients with FBXW7 loss and without MDM4 gain or APC loss, those with MDM4 gain and/or APC loss and without FBXW7 loss, and those with other CNA combinations (log-rank test, P < 0.01). Conclusion: MDM4 gain, APC loss, and FBXW7 loss are the independent prognostic factors for extrohepatic metastasis-free survival after the operation for HCC and can be used to predict the risk of extrohepatic metastasis after the operation for HCC.
