Shanghai Journal of Acupuncture and Moxibustion 2017;36(2):175-179
Objective To observe the effect of pre-intervention with electroacupuncture on oxidative stress (OS) and inflammatory reaction after hepatectomy under portal occlusion.Method Thirty patients going to receive hepatectomy under Pringle's portal occlusion were randomized into an electroacupuncture group and a sham electroacupuncture group, 15 cases each. Three days prior to the surgery, the patients started to receive corresponding acupuncture or sham electroacupuncture treatment by selecting bilateral Riyue (GB24), Qichong (ST30) and Yanglingquan (GB34), once a day. The anesthesia method was general (inhalational and intravenous) anesthesia. Central venous blood was drawn before the surgery, and respectively 6 h, 24 h, 48 h and 72 h after the surgery to examine the OS-relatedparameters, superoxide dismutase (SOD) and malondialdehyde (MDA), as well as the inflammatory mediators, including tumor necrosis factor-α(TNF-α), interleukin (IL)-1, IL-6, and IL-10.Result Compared to the sham electroacupuncture group, the SOD activity significantly increased (241±11.4 U/mL,180±12.6 U/mL,P<0.05) and the MDA level significantly dropped in the electroacupuncture group at 6 h and 24 h after the surgery(11.0±0.8 mmol/L,10.0±0.9 mmol/L,P<0.05); there were no significant between-group differences in the rest indexes (P>0.05).Conclusion Pre-intervention with electroacupuncture can up-regulate the activity of SOD and down-regulate the level of MDA in patients after hepatic portal occlusion, and thus partially reduce OS, but it doesn't shownoticeable effecton inflammatory response.

Tianjin Medical Journal 2015;(7):762-764
Objective To analyze the relationship between serum 25 hydroxy vitamin D (25OHD) levels and semen pa?rameters. Methods The serum levels of 25OHD were examined in 68 healthy men, who were divided into three groups. Twenty-two cases were included in 25OHD normal group (30μg/L≤25OHD<40μg/L), 20 cases were in 25OHD relatively insufficient group (20μg/L≤25OHD<30μg/L), and 26 cases were in 25OHD deficiency group (25OHD<20μg/L). The se?rum reproductive hormones including follicle stimulating hormone (FSH), luteinizing hormone (LH), estradiol (E 2), prolactin (PRL) and testosterone (T) were detected by chemiluminescence immune analysis. Semen samples were collected by mastur?bation after a period of abstinence for 3 and 7 days. The total sperm count, sperm concentration, percentage of progressive motile sperm and percentage of normal morphology sperm were measured by sperm quality analyzer. Results There were no significant differences in FSH, LH, E2, PRL and T levels between three groups, and which were all in normal ranges. The total sperm count, sperm concentration, percentage of progressive motile sperm and percentage of normal morphology sperm were significantly lower in 25OHD relatively insufficient group and 25OHD deficiency group than those in 25OHD normal group. The total sperm count and the percentage of progressive motile sperm were significantly lower in 25OHD deficiency group than those in 25OHD relatively insufficient group (P<0.05). There were no statistical differences in sperm concentra?tion and percentage of normal morphology sperm between 25OHD deficiency group and 25OHD relatively insufficient group. Conclusion The decrease of semen quality may be related to serum 25OHD at the relatively insufficient and deficiency lev?els. The effect of 25OHD on semen parameters may not be mediated by reproductive hormones.
