Objective:To investigate the relationship of lipid peroxide (LPO), total oxidation state (TOS), apolipoprotein (a) [apolipoprotein(a), Apo(a)] and pregnancy outcome in patients with polycystic ovarian syndrome (PCOS) treated by ovulation induction-in vitro fertilization-embryo transfer (IVF-ET).Methods:The clinical of 215 patients with PCOS treated by IVF-ET who were admitted to Hengshui People′s Hospitalfrom May 2017 to February 2020 were collected and they were divided into clinical pregnancy group (155 cases) and biochemical pregnancy group (60 cases) according to pregnancy outcome. The levels of LPO, TOS, and Apo(a) in the peripheral blood of the two groups were detected and the data were analyzed.Results:The levels of LPO and TOS before ovulation induction and human chorionic gonadotropin (HCG) dayin the biochemical pregnancy group were higher than those in the clinical pregnancy group: (10.35 ± 3.67) μmol/L vs. (7.16 ± 1.59) μmol/L, (17.98 ± 3.15) mmol H 2O 2 equiv/L vs. (15.03 ± 3.21) mmol H 2O 2 equiv/L; (12.81 ± 4.09) μmol/L vs. (7.38 ± 2.14) μmol/L, (19.66 ± 3.02) mmol H 2O 2 equiv/L vs. (15.19 ± 3.34) mmol H 2O 2 equiv/L; and the level of Apo(a) was lower than that in the clinical pregnancy group: (379.8 ± 95.9) mg/L vs. (486.5 ± 100.3) mg/L, (335.8 ± 84.7) mg/L vs. (473.5 ± 112.9) mg/L, the differences were statistically significant ( P<0.05). LPO and TOS before ovulation induction and HCG day were negatively correlated with the number of high-quality embryos ( P<0.01), and Apo(a) was positively correlated with the number of high-quality embryos ( P<0.01). The risk of non-clinical pregnancy for those with LPO, TOS, Apo(a) higher than the average before ovulation induction was 1.435, 1.233, 0.678 times of those with lower than the average ( P<0.05). The risk of non-clinical pregnancy for those with LPO, TOS, and Apo(a) higher than the average on HCG day was 1.443, 1.689, 0.762 times of those with lower than average ( P<0.05). After receiver operating characteristic (ROC) curve analysis, the area under the curve(AUC) of all indicators before ovulation induction combined to predict clinical pregnancy was 0.844. The AUC of all indicators on HCG day combined to predict clinical pregnancy was 0.894. Conclusions:Peripheral blood LPO, TOS, Apo(a) levels are closely related to the number of high-quality embryos, and are the main influencing factors of pregnancy outcome. Therefore, dynamic monitoring of the above-mentioned index levels can provide a reference for the clinical improvement of the treatment plan.

OBJECTIVE: To study the effect of electro- acupuncture at Zusanli acupoint in regulating perioperative cell immune functions in rats. METHODS: Forty-two SD rats were divided into blank control group (=6), model group (=18), and electroacupuncture group (=18). The rats in the latter two groups underwent thigh incision and femoral dissection under anesthesia; the rats in electro-acupuncture group received electro-acupuncture at bilateral Zusanli acupoint for 15 min before anesthesia and 1 h after the surgery. The rats in the model group and electro-acupuncture group were sacrificed at 6 h, 24 h, and 72 h after the operation and blood samples were taken from the ventricle for analyzing CD3, CD4, and CD8 T cell subpopulations and calculation of CD4/CD8 using flow cytometry. ELISA was used to detect the levels of interleukin-1 (IL-1) and IL-6. RESULTS: The CD3 T cell subpopulation was significantly lower in the model group and electro-acupuncture group than in the blank group at 6 h and 24 h after the operation. At 72 h after the operation, CD3 subpopulation levels still remained low in the model group, but recovered the control level in electro-acupuncture group. At each time point of measurement, CD3 level was significantly lower in the model group than in the electro-acupuncture group. CD4 level in the model group was significantly lowered at 6 h and 24 h after the operation, and recovered the control level at 72 h. In the electro-acupuncture group, CD4 level was significantly lowered at 6 h after the operation, but recovered the control level at 24 h. At 24 h and 72 h, the levels of CD4 were significantly lower in the model group than in the electro-acupuncture group. CD8 level underwent no significant changes after the operation in either the model group or electro-acupuncture group. CD4/CD8 was significantly lowered at 24 h and 72 h after the operation in the model group but showed no significant variation in the electro-acupuncture group. Compared with that in the control group, IL-1 level was significantly lowered in both the model group and electroacupuncture group at 6 h, 24 h, and 72 h after the operation, and was significantly lower in the model group than in the electroacupuncture group at these time points. IL-6 level increased significantly in the model group and the electro- acupuncture group at 6 h and 24 h. at 72 h, IL-6 level was obviously lowered in the electro-acupuncture group but remained elevated in the model group. CONCLUSIONS Electro-acupuncture alleviates postoperative immune suppression and promotes recovery of the immune function in rats, suggesting a protective effect of electro-acupuncture at Zusanli acupoint on cellular immune function after surgery.

OBJECTIVE: To compare the efficacy and safety of postoperative analgesia with low-dose sufentanil combined with transversus abdominis plane (TAP) block and with sufentanil alone in promoting patients'recovery following laparoscopic hysterectomy. METHODS: Sixty patients undergoing laparoscopic hysterectomy in our hospital between September, 2016 and August, 2017 were randomly allocated into two equal groups. In group A, the patients were given postoperative analgesia with 1 μg/kg sufentanil, 9.96 mg tropisetronmesylate, and 200 mg flurbiprofen axetil (diluted with 0.9% NaCl solution to 100 mL, pumped at the rate of 2 mL/h) combined with TAP block; in group B, the patients received similar postoperative analgesia but at a higher dose of sufentanil (2 μg/kg) without TAP block. Visual analogue scale (VAS) was used to evaluate pain at 15 min and at 4, 8, 12, 24 and 48 h postoperatively, and the first off-bed time, the length of postoperative hospital stay and the incidence of postoperative nausea and vomiting (PONV) were recorded in all the patients. RESULTS: Compared with those in group B, the patients in group A had significantly lower VAS scores at 15 min, 4 h, 8 h, and 12 h postoperatively ( < 0.01) with also statistically shorter first off-bed time and postoperative hospital stay ( < 0.01). Two (6.7%) patients in group A had mild PONV, and 6 (20.0%) in group B had PONV (including 4 with mild and 2 with moderate PONV). CONCLUSIONS Lowdose sufentanil combined with TAP block is effective for postoperative analgesia after laparoscopic hysterectomy and helps to reduce the incidence of PONV and shorten the first off-bed time and postoperative hospital stay to promote the recovery of the patients.

OBJECTIVE: To investigate the molecular mechanism underlying the inhibitory effect of propofol on pyroptosis of macrophages. METHODS: Macrophages derived from bone marrow were extracted and divided into three groups: control group, LPS+ATP group and propofol+LPS+ATP group. The control group was not given any treatment; LPS+ATP group was given LPS 1 μg/mL stimulation for 4 h, then ATP 4 mM stimulation for 1 h; Propofol+LPS+ATP group was given propofol+LPS 1 μg/mL stimulation for 4 h, then ATP stimulation for 1 h. After treatment, the supernatant and cells of cell culture were collected. the cell activity was detected by CCK8 and flow cytometry. The inflammatory cytokines IL-1βand IL-18 were detected by Elisa. Western blot was used to detect the expression of caspase-1 protein and TLR4 on cell membran Immunohistochemical fluorescence was used to detect apoptosis of cells. RESULTS: LPS+ATP significantly decreased the viability of the macrophages and increased the cellular production of IL-1β and IL-18, activation of caspase-1 protein and the expression of TLR-4 on the cell membrane ( < 0.05). Treatment with propofol obviously reversed the changes induced by LPS+ATP. CONCLUSIONS LPS+ATP can induce pyroptosis of mouse bone marrow-derived macrophages, and propofol effectively inhibits such cell death, suggesting that propofol anesthesia is beneficial during operation and helps to regulate the immune function of in patients with sepsis.
