OBJECTIVETo investigate the semen quality of cancer patients and search for a better way of sperm cryopreservation for them.

METHODSWe retrospectively analyzed the quality of the semen from 43 cancer patients under cryopreservation in the Sperm Bank of Zhejiang Province, and compared the semen parameters between the cancer patients and 248 normal donors as well as between the testicular cancer cases (n=22) and non-testicular cancer cases (n=21).

RESULTSThe cancer patients exhibited significantly lower semen quality than the normal donors as in sperm concentration (60.90 x 10(6)/ml vs 74.27 x 10(6)/ml), progressive motility (41.07% vs 51.79%), and recovery rate (49.98% vs 57.33%) (all P <0.05). Furthermore, the progressive sperm motility and sperm recovery rate after freezing were significantly decreased in the testicular cancer cases (15.68% and 42.81%) than in the non-testicular cancer cases (28.36% and 57.53%) (both P <0.05).

CONCLUSIONSemen quality declines in cancer patients, and therefore early sperm cryopreservation is essential for them. Due to the poor sperm motility and recovery rate of testicular cancer patients after freezing, further investigation is required on the improvement of sperm cryopreservation methods.

Objective To investigate the clinical effects of gastrointestinal decompression with enteral feeding tube in elderly patients with gastric cancer.Methods 78 cases of gastric cancer patients undergoing postoperative gastric decompression with enteral feeding tube were selected as the treatment group,and 66 patients with gastric cancer undergoing postoperative intravenous nutrition and gastric decompression with routine nasogastric tube as the control group in our hospital from January 2015 to December 2015.The incidence rate of gastric tube patency,faster postoperative recovery,nutritional immune improvement,adverse reaction and complication were compared between the two groups.Results The incidence rate of adverse reactions and complications in treatment group were significant lower than in control group (3.0 ％ vs.12.8 ％,x2 =4.4857,P =0.0342;1.5 ％ vs.10.2％,x2 =4.6620,P =0.0308,respectively).Following parameters were significant better in treatment group versus in control group:the time of evacuating [(3.1 ± 0.3) d vs.(4.0 ± 0.1) d,t =24.9227,P =0.0000],defecation[(4.3 ± 0.6) d vs.(5.5 ± 1.1) d,t =7.9189,P =0.0000],extubation [(5.3±1.3)d vs.(10.1±2.2)d,t=15.5690,P=0.0000],hospitalization[(12.3±2.5)d vs.(18.6± 3.2)d,t=12.9864,P=0.0000],postoperative body weight[(57.2±4.9)kg vs(49.0±7.2)kg,t=-7.8408,P=0.0000],plasma protein[(133.2± 11.2)g/L vs(104.5± 10.3)g/L,t=-16.0055,P=0.0000],hemoglobin[(4.7 ± 1.0) g/L vs (3.2 ± 0.6) g/L,t =-11.0991,P =0.0000] and peripheral blood lymphocyte count[(3.5 ± 0.7) × 109/L vs (2.1 ± 0.4) × 109/L,t =-15.0088,P =0.0000].Conclusions Effects of postoperative gastrointestinal decompression in elderly patients with gastric cancer are similar between with routine gastric tube and with enteral feeding tube.However,the enteral feeding tube-induced enteral nutrition shows fewer side effects and complications,better nutritional and immune effects,and faster postoperative recovery,which is worthy of a generalization and application.

Our previous research indicated that the Streptomyces pactum Act12 (Act12) had a certain promotional effect on tanshinone accumulation and up-regulated the expression of genes 3-hydroxy-3-methyglutaryl-CoA reductase (HMGR) and 1-deoxy-d-xylulose-5-phosphate reductoisomerase (DXR) in Salvia miltiorrhiza hairy roots. This study focuses on the roles of reactive oxygen species in S. pactum Act12-induced tanshinone production in S. miltiorrhiza hairy roots. The 4% Act12, 4% Act12 + CAT and 4% Act12 + SOD were added to S. miltiorrhiza hairy root and subcultured for 21 days, the dry weight, contents of reactive oxygen species, contents of tanshinones and expression of HMGR and DXR were determined at different harvest-time. The generation of reactive oxygen species (ROS) in S. miltiorrhiza hairy roots was triggered by 4% Act12 treatment. The relative expressions of genes HMGR and DXR in 4% Act12 treatment were 32.4 and 4.8-fold higher than those in the control. And the total tanshinone in the hairy roots was 10.2 times higher than that of the control. The CAT and SOD could significantly inhibit the ROS accumulation and relative expressions of genes HMGR and DXR in 4% Act12 treatment, which induced the total tanshinone content was decreased by 74.6% comparing with the 4% Act12 treatment. ROS mediated Act12-induced tanshinone production. The Act12 may be via the ROS signal channel to activate the tanshinone biosynthesis pathways. Thereby the tanshinon content in hairy roots was increased.

OBJECTIVETo investigate the relationship of seasonal variation with pre- and post-thaw semen parameters as well as the cryosurgical of human spermatozoa.

METHODSA total of 6 414 semen samples were collected from 1 135 donors aged 22 - 32 years by Zhejiang Human Sperm Bank, and divided into spring, summer, autumn and winter groups according to the time of collection. All the samples underwent routine seminal analysis, and the sperm parameters were compared between different seasons. The sperm specimens were cryopreserved in aliquots and analyzed after thawing.

RESULTSThe semen volume was (2.92 +/- 1.17) ml in spring, significantly higher than in summer, autumn and winter ([2.71 +/- 1.07 ], [2.74 +/- 1.15] and [2.83 +/- 1.15] ml, P < 0.05). Sperm density was the highest in autumn ([105.60 +/- 39.76] x 10(6)/ml) as compared with the other three seasons ([101.18 +/- 40.16] x 10(6)/ml, [93.54 +/- 35.10] x 10(6)/ml, and [101.29 +/- 38.37] x 10(6)/ml, P < 0.05). The sperm progressive motility was the highest in spring ([58.49 +/- 10.04] %) and the cryosurgical of sperm the lowest in summer, with statistically significant differences from the other groups (P < 0.05).

CONCLUSIONSeasonal variations affect human semen quality and cryosurgical of sperm. The semen volume, the percentage of progressive motile sperm, the cryosurgical of sperm, and the post-thaw density of progressive motile sperm are higher in spring than during the rest of the year.
