Objective To investigate the effect of dexmedetomidine on median effective target effect-site concentration ( EC50) of sufentanil inhibiting body movement evoked by skin incision in patients undergoing bilateral subtotal thyroidectomy. Methods Thirty-nine ASA I or II patients of both sexes aged 20-64 yr with a body mass index of 20-25 kg/m2 undergoing bilateral subtotal thyroidectomy were randomly divided into 2 groups: control group (group C) and dexmedetomidine group (group D). The patients were premedicated with intramuscular phenobarbital 0.1 g and scopolamine 0.3 mg. In group D dexmedetomidine 0.6 μg/kg was injected iv over 10 min at S min before induction of anesthesia. Anesthesia was induced with target-controlled infusion (TCI) of propofol and sufentanil. The target plasma concentration of propofol was set at 3.0 μg/ml which was maintained until the end of operation. TCI of sufentanil was started at 10 min after initiation of propofol TCI. The initial target effect-site concentration was set at 0.20 ng/ml and decreased/increased by 20% in the next patient according to whether the patient's body moved or not within 1 min after skin incision. Laryngeal mask airway was inserted at 3 min after initiation of sufentanil TCI. Spontaneous breathing was maintained. Skin incision was made at 10 min after initiation of sufentanil TCI. The EC50 and 95% confidence interval (CI) of sufentanil inhibiting skin incision-evoked body movement were calculated with sequential method. Results EC50, of sufentanil was 0.1148 ng/ml (95% CI 0.1055-0.1249 ng/ml) in group D and 0.1454 ng/ml (95% CI 0.1339-0.1580 ng/ml) in group C, and was significantly lower in group D than in group C. Conclusion Dexmedetomidine 0.6 μg/kg infused iv before operation can reduce the EC50 of sufentanil inhibiting body movement evoked by skin incision in patients undergoing bilateral subtotal thyroidectomy.

Objective To investigate the proliferation, immune phenotype and cytotoxicity on different cell lines of cytokine-induced killer (CIK) cells collected from healthy donors. Methods Peripheral blood mononuclear cells (PBMC) from healthy donors were induced to become CIK cells by adding cytokines including rhIL-2, rhIFN-γand CD3 McAb. The proliferation of CIK cells was tested by blood cell recording board. The CIK cells were analyzed on different time points by FACS. The cytotoxicity of CIK cells against different tumor cell lines, such as K562, BJAB, A549, MCF-7 and HepG2, was detected by MTT assays on day 13. Results CIK cells quickly proliferated from day 5, and expanded by 182-fold after 20-day culture. The immunophenotypes of CD3+, CD3+CD8+and CD3+CD56+were (97.83±1.03)%, (77.12±1.60)%and (27.58± 2.02)%. The percentages of CD3+, CD3+CD8+and CD3+CD56+increased noticeably (P＜0.01). According to the effector-tar-get ratio of 40∶1, the activity of CIK cells against tumor cells K562, BJAB, A549, MCF-7 and HepG2 were (88.89±7.22)%, (75.42±9.52)%, (63.19±5.67)%, (43.53±5.67)%and (42.63±7.69)%. The experiments showed that CIK cells possessed high-er antitumor cytotoxic activity. Conclusion CIK cells can be largely capacity cultured by adding cytokines in vitro. CIK cells were a highly efficient cytotoxic cell against tumors, and had clinical application potentials.

Objective To compare the efficacy of different analgesia regimens in elderly patients with femoral neck fracture undergoing posture changing during epidural anesthesia. Methods Ninety patients (35 males,55 females,aged 65-90 years,48-78 kg)with femoral neck fracture who would be treated with artificial femoral head replacement were randomly divided into 3 groups (n = 30 each):femoral nerve block group (group FNB),fascia iliaca compartment block group (group FIC)and intravenous group (group IV).Femoral nerve block or fascia iliaca compart-ment block was performed 30 min before epidural anesthesia (EA)in FNB group or FIC group re-spectively.Fentanyl 0.5 μg/kg was injected intravenously 3 min before EA.In the three groups,addi-tional 0.25 μg/kg fentanyl was administrated intravenously to keep the VAS scores <4 before posi-tioning.EA was performed between L1-2 in a position of troubled leg upper,and patients returned to supine position after epidural catheterization.The VAS scores at T0 (after entering the operation room),T1 (in supine posture before EA),T2 (before posture changing),T3 (while supine from lateral posture after EA),T4 (3 min after T3 ),the time for achieving EA,the fentanyl consumption, the cases of cardiovascular events and hypoxemia was recorded.Results Compared with group IV, VAS scores at T1 ,T2 ,the fentanyl consumption,time for achieving EA,and incidence of cardiovas-cular events and hypoxemia in group FNB and group FIC decreased significantly (P <0.05 or 0.01). There was no significant difference between group FNB and group FIC.Conclusion Preemptive anal-gesia regimens through both femoral nerve block and fascia iliaca compartment block during epidural anesthesia can reduce the fentanyl consumption,as well as decrease the incidence of cardiovascular e-vents and hypoxemia.

Objective To evaluate the effect of comprehensive schistosomiasis control measures based on infection source control in Hanchuan City marshland and lake endemic regions . Methods The data of comprehensive schistosomiasis control in Hanchuan City from 2004 to 2013 were collected and the change trends of the Oncomelania hupensis snail status and the in?fection situation of human and livestock were analyzed to evaluate the control effect. Results After the implementation of the comprehensive measures the infection rates of residents and cattle decreased from 6.38%and 8.11%in 2004 to 0.16%and 0 in 2013 respectively. There were no acute schistosomiasis patients since 2007 no new infection cases since 2011 and no infected snails since 2012. Compared with 2004 the occurrence rate of frames with living snails and the average density of living snails decreased by 56.78%and 68.35% respectively but the snail area and susceptible area increased by 0.62%and 7.10% respec?tively. In 2013 all the 367 endemic villages in 26 townships reached the criteria of transmission controlled. Conclusions The comprehensive schistosomiasis control measures based on infection source control can control the schistosomiasis transmission effectively in marshland and lake endemic regions. When consolidating the achievement the snail area in inner embankment should be compressed to prevent the schistosome re?infection in human and livestock.

OBJECTIVETo improve the method of indirubin in serum by HPLC and apply to pharmacokinetics in rats.

METHODChromatographic separation was conducted on an C18 column (4.6 mm x 250 mm, 5 microm), using a mixture of methanol-water (75:25) as mobile phase at a flow rate of 1.0 mL min(-1) with UV detection at 289 nm, the column temperature was at 35 degrees C and ethinyl estradiol was used as an internal standard. Rats were administered i. v. bolus of indirubin in doses of 2.0 and 4.0 mg x kg(-1) through a jugular vein catheter, respectively. Serial blood samples (about 100 microL) were individually collected at 2, 5, 10, 20, 30, 60, 90, 120, 180 min after administration, and the concentrations of indirubin determined were in rat serum by HPLC. The pharmacokinetic parameters were calculated with the Winnonlin 5.0 software.

Objective:To analyze the clinical features, postoperative recurrence and prognostic factors of young patients with cervical cancer.Methods:The clinical data of hospitalized cervical cancer patients in the Affiliated Hospital of Qingdao University from January 2004 to March 2019 were retrospectively studied. 243 young cervical cancer patients ≤35 years old were selected as the study group. The method of case-control study was adopted. In the same period, 250 first and second cervical cancer patients aged >35 years were randomly selected as the control group. The clinical data of the two groups were compared, and the survival curves of the two groups were analyzed. The clinical data of patients with postoperative recurrence (17 cases) and patients without recurrence (164 cases) in the study group were compared, and the related data affecting the prognosis of young cervical cancer patients were analyzed by univariate and multivariate analysis. Statistical data were compared by χ 2 test or exact probability method. Kaplan-meier method was used to estimate survival rate and draw survival curve. Survival rate was compared by Long-Rank test. COX regression model was used for multivariate analysis. Results:Compared with the control group, the young cervical cancer patients had earlier age of marriage, menstruate, fewer pregnancies, no preoperative adjuvant therapy, more nerve infiltration and ovarian preservation, the difference was statistically significant (χ 2 values were 94.58, 67.54, 60.53, 5.44, 13.64, 5.51, and 118.24, respectively; P values were <0.001, <0.001, <0.001, 0.025, 0.022, <0.001, respectively). The proportion of irregular vaginal bleeding in study group (13.17%(32/243)) was lower than that in control group (30.40%(76/250)), and the proportion of contact vaginal bleeding (52.26%(127/243)) was higher than that in control group (43.20%(108/250)). There were significant differences between the two groups (χ 2 values were 21.39 and 4.06, respectively; P values were < 0.001 and 0.044, respectively). There was no significant difference in Kaplan-Meier survival rate between the study group and the control group (χ 2=0.03, P=0.859). Univariate analysis showed that the International Federation of Gynecology and Obstetrics(FIGO), whether to retain ovary, depth of cervical invasion, nerve invasion, lymphatic vascular space invasion and pelvic lymph node metastasis were the influencing factors of 5-year survival rate of young cervical cancer patients ( P values were 0.016, 0.008, 0.014, 0.017, 0.004, <0.001, respectively). Multivariate analysis showed FIGO staging ( OR=2.073, 95% CI: 1.017-4.228, P=0.045), lymphatic vascular space infiltration ( OR=0.041, 95% CI: 0.005-0.341, P=0.019) and pelvic lymph node metastasis ( OR=0.027, 95% CI: 0.004-0.197, P<0.001) were risk factors affecting the prognosis of young cervical cancer. The patients with low FIGO stage, no lymphatic vascular space infiltration and pelvic lymph node metastasis have a good prognosis. Conclusion In young patients with cervical cancer, the first clinical feature is mainly contact vaginal bleeding. The prognosis of young patients with cervical cancer and 5 years survival rate there was no statistically significant difference compared with control group. The later FIGO staging , no ovarinan retention and the deeper cervical infiltration depth , with the nerve or between lymphatic vascular invasion and pelvic lymph node metastasis in young patients with cervical cancer had poor prognosis, and FIGO stage, lymphatic vessel space invasion and pelvic lymph node metastasis were the most significant factors.

Objective To investigate the effect of human amniotic epithelial cell(hAEC)transplantation on endometrium improvement and matrix metalloproteinase 8(MMP-8)and vascular endothelial growth factor(VEGF)expression in a rat model of uterine scaring.Methods The uterine scar model was established in rats that were randomly divided into model and transplantation groups with 18 rats in each group.The other 18 rats were used as the sham operation group.Rats in the transplantation group were injected with hAECs in the uterine scar,and rats in model and sham operation groups were administered the same amount of PBS.After 4 weeks,the uterine tissues of eight rats in each group were collected.Histomorphological changes and endometria fibrosis were observed by HE staining and Masson staining respectively,and the endometrial thickness and number of glands were measured.Endometrial growth and receptivity were evaluated by immunohistochemical staining of cytokeratin and integrin β3,respectively.mRNA expression of MMP-8 and VEGFA in endometrial tissues was measured by RT-qPCR.Western blot was used to measure MMP-8 and VEGFA protein expression.After 8 weeks,the remaining 10 rats in each group were used to assess gestational ability.Results The endometrial thickness,gland number,IOD value of keratin and integrin β3,relative mRNA and protein expression levels of MMP-8 and VEGFA,pregnancy rate and number of uterine embryos in model and transplantation groups were lower than those in sham operation group(P<0.05).The endometrial thickness,gland number,IOD value of keratin and integrin β3,relative mRNA and protein expression of MMP-8 and VEGFA,pregnancy rate and number of uterine embryos were higher than those in model group(P<0.05).Additionally,hAEC transplantation improved the pathological morphology of endometrial tissue in rats with uterine scaring and reduced the degree of endometrial fibrosis.Conclusions hAEC transplantation improves endometrial injury,reduces scar formation,improves endometrial receptivity,and enhances pregnancy function in model rats,which may be related to promotion of MMP-8 and VEGFA expression.
