Résumé

This study analyzed the effects of male age and abstinence time on semen quality and explored the best abstinence time for Chinese males among different age groups. Semen parameters, including sperm kinetics, morphology, and DNA fragmentation index (DFI), were reviewed from 2952 men. Samples were divided into six age groups (≤25 years, 26-30 years, 31-35 years, 36-40 years, 41-45 years, and >45 years) and were divided into six groups according to different abstinence time (2 days, 3 days, 4 days, 5 days, 6 days, and 7 days). The differences in semen quality between the groups were compared, and the effect of age and abstinence time on semen quality was analyzed. Significant differences were observed in semen volume, progressive motility (PR), and DFI among the age groups (all P < 0.05), and no significant differences were observed in sperm morphological parameters (all P > 0.05). There were significant differences in semen volume, PR, and DFI among different abstinence time groups (all P < 0.05) and no significant differences in sperm morphological parameters (all P > 0.05). Pearson analysis showed that male age and abstinence time were both significantly correlated with sperm kinetics and DFI (both P < 0.05), while no significant correlation was found with sperm morphological parameters (all P > 0.05). The box plots and histograms of men's age, abstinence time, and semen quality show that most semen quality parameters differ significantly between the 2 days and 7 days abstinence groups and other groups at different ages. Except for the sperm morphology parameters, sperm kinetic parameters and sperm DFI are linearly related to male age and abstinence time.

Résumé

<p><b>OBJECTIVE</b>To observe the efficacy of Chinese medicine comprehensive therapeutic project in treating the middle/late stage primary hepatic carcinoma (PHC).</p><p><b>METHODS</b>With prospective randomized controlled design, 97 patients with PHC were assigned to the test group (49 cases) treated with Chinese medicine comprehensive therapy using Oleum fructus bruceas intervention combining oral intake of Ganji Decoction and external application of Ailitong, and the control group (48 cases) treated with chemotherapeutic agents combining iodized oil chemo-embolization and analgesics. The immediate and long-term efficacy, adverse reaction, pain-relieving initial time (PRIT) and pain-relieving sustained time (PRST) of the treatment, as well as the change in relieving patients' quality of life (QOL) were observed.</p><p><b>RESULTS</b>The difference between the two groups in illness control rate was statistically insignificant (P>0.05), but the adverse reaction occurrence rate in the test group was lesser than that in the control group (P<0.05). PRIT was insignificantly different in the two groups (P>0.05), but the PRST was significantly superior in the test group than that in the control group (10.37+/-2.18 h vs 7.78+/-1.95 h, P<0.01). After treatment, the increased Karnofsky scores in the test group indicated that the patients' somatic activity, symptoms and QOL were improved significantly, which were significantly superior to those in the control group (P<0.05). The survival rate in the two groups was similar at the 3rd month after treatment, but the test group did show superiority in terms of half- and 1-year survival rate (65.9% vs 42.5% and 38.6% vs 18.1%, respectively, P<0.05). The median survival time in the test group was 8.9 months and that in the control group was 5.3 months.</p><p><b>CONCLUSION</b>Chinese medicine comprehensive therapy is an effective treatment for the middle/late stage patients of PHC, and it could extend the PRST, improve the patients' QOL and long-term survival with less adverse reaction.</p>

Résumé

The porcine interferon-gamma (PoIFN-gamma) gene, in which the sequence encoding signal peptide was replaced by that of the alpha-factor of Saccharomyces cerevisiae, was cloned into Pichia pastoris expression vector pPIC9K. The recombinant plasmid pPIC9K-alpha-PoIFN-gamma was then transformed into Pichia pastoris GS115 cells by electroporation and stable multicopy recombinant Pichia pastoris strains were selected by G418 resistance. Two recombinants of multiple inserts were obtained. SDS-PAGE and Western blot assays of culture broth from a methanol-induced expression strain demonstrated that recombinant PoIFN-gamma, 17kD and 23kD proteins, were secreted into the culture medium. Target proteins, 60% of total proteins, were obtained in the culture medium at the concentration of 108 mg/L. This is the first secreted expression of porcine interferon-gamma gene in Pichia pastoris.
