Objective To study the cytotoxic activity of Chinese compound prescription (Xiaozheng Yiliu Decoction) combined with cisplatin on human ovarian cancer OVCAR/DDP cells and its molecular mechanism. Methods The xenograft model was established by injection of OVCAR/DDP cells. Forty nude mice were randomly allocated into four groupsincluding control group, cisplatin treatment group, low-dose Xiaozheng Yiliu plus cisplatin treatment group,and high-dose Xiaozheng Yiliu plus cisplatin treatment group.The apoptosis was determined by TUNEL analysis.The survivin expression was detected by RT-PCR analysis.Results The inhibit rates in cisplatin treatment group, low-dose Xiaozheng Yiliu plus cisplatin treatment group,and high-dose Xiaozheng Yiliu plus cisplatin treatment group,were(5.56±1.14) ％,(18.42±7.73) ％,and (31.59±12.58) ％,respectively,and there were significant differences among the groups(F=8.64,P＜0.01 ).The TUNEL analysis showed that the percentages of cell apoptosis were(2.35±1.04) ％,(4.56±1.61) ％,(12.42±3.68) ％,(21.59±5.17) ％ in four different groups,respectively.After treated by Xiaozheng Yiliu Decoction,the mRNA expression of survivin was found to be down-regulated by RT-PCR analysis. Conclusion Xiaozheng Yiliu Decoction could iucrease the cytotoxic activity of cisplatin on ovarian cancer OVCAR/DDP cells, which may be related to the down-regulation of survivin gene expression.

Scanning electron microscopic observations were made on the morphological structures of the two copulatory spicules of the male Necator americanus and Ancylostoma duodenale. In both species,one of the two copulatory spicules was in the shape of a concave groove and the other, in the shape of an oblate tube. Owing to the difference in the concavity of the groove shaped copulatory spicule between the two species as shown by the cross sections, Necator americanus usually appear to have only one copulatory spicule whereas Ancylostoma duodenale usually show two separate copulatory spicules in appearance (Figs 1 -10).

The autonomic nervous function, blood pressure, coordinate motor and blood alcohol Concentration (BAG) of twenty-one healthy Han volunteers were examined before and after alcohol intake. The purpose was to assess the acute effects of low and moderate doses of alcohol on their coordinate motor and autonomic nervous function. The results showed that after alcohol intake the subjects' heart rate increased and the total power value (TPV) decreased significantly. After the intake of alcohol at low dose, the parasympathetic nervous function of the subjects lying supoine was inhibited significantly. After the intake of alcohol at moderate dose, both the parasympathetic and the sympathetic nervous functions were inhibited. After the intake of alcohol at low dose, both the systolic pressure and the diastolic pressure of the subjects standing up-right were decreased and the diastolic pressure of those lying supine were also decreased. After the intake of alcohol at moderate dose, the systolic and diastolic pressures of the subjects, either lying supine or standing up-right, were decreased. Some subjects showed ataxia after the intake of alcohol at low dose ,and some showed aggravated ataxia after intake of alcohol at moderate dose of alcohol. There was no relationship of BAG with the degree of changes in autonomic nervous function, blood pressure and ataxia. The results indicated that ataxia was induced to come on and the autonomic nervous function was inhibited in some subjects who had taken low and moderate doses of alcohol ,and the cardiovascular regulation was affected too. These suggested that the increase of alcohol intake is adverse to human body's adaptation to the sharp change of circumstance.

Objective To explore if bacillus bifidus relieve CPFX-induced testosterone reduction in mouse testes.Methods Twenty-four male mices were divided into 4 groups, then administered saline for 6 days (Sal6 group), CPFX for 6 days (A6 group), CPFX for 6 days followed by bifidobacteria treatment for the next 6 days (A6+P6 group), CPFX for 6 days and then saline for the next 6 days (A6+Sal6 group).We detected serum levels of testosterone by RIA, as well as levels of steroidogenic enzymes mRNA [cholesterol side-chain cleavage enzyme (P450scc) and steroidogenic acute regulatory protein (StAR)] and NF-E2-related factor2 (Nrf2) mRNA in testes by real-time PCR, Nrf2, heme oxygenase-1 (HO-1), and 4-hydroxy-2-nonenal (4-HNE) by Western blot and4-HNE by Immunohistochemistry.Results The A6 group had significantly lower serum testosterone levels compared with the Sal6 group (P<0.001), the A6+P6 group had significantly higher compared with the A6 (P<0.001) and A6+Sal6 groups (P<0.01).The A6 group had significantly lower StAR mRNA compared with the Sal6 group (P<0.001), the A6+P6 group had significantly higher level compared with the A6 (P<0.01) and A6+Sal6 groups (P<0.01).The A6 group had significantly lower P450scc mRNA as compared with the Sal6 group (P<0.001), the A6+P6 group had significantly higher compared with the A6 (P<0.001) and A6+Sal6 groups (P<0.05).The A6 group had significantly lower Nrf2 compared with the Sal6 group (P<0.001), the A6+P6 group had significantly higher compared with the A6(P<0.01) and A6+Sal6 groups (P<0.05).The A6 group higher 4-HNE expression compared with the Sal6 group, the A6+P6 group had significantly lower compared with the A6 (P<0.01) and A6+Sal6 groups (P<0.05).Conclusions Bifidobacteria the reduction of CPFX-induced testosterone reduction, and these effects may potentially explained by Nrf2 inflammatory signaling pathway.

Objective To investigate the clinical efficacy and experiences of laparoscopic hepatectomy (LH) for segment Ⅶ and Ⅷ liver tumors.Methods The retrospective cross-sectional study was conducted.The clinicopathological data of 94 patients who underwent LH for segment lⅦ or Ⅷ liver tumors in the Sir Run Run Shaw Hospital Affiliated to Zhejiang University School of Medicine from June 2010 to August 2016 were collected.The operating space for operation was built under laparoscopy.According to liver cirrhosis grading,tumor size,adjacent relationship with major blood vessels and residual liver volume,non-anatomical and anatomical hepatectomies were selected by patients.During the operation,tumors were precisely pinpointed and plane of liver resection was determined,and then proper instruments of liver partition and techniques of hepatic inflow occlusion were selected.Observation indicators:(1) surgical and postoperative recovery situations;(2) postoperative pathological examination;(3) follow-up and survival situation.Follow-up using outpatient examination and telephone interview was performed to detect the patients' survival up to July 2017.Measurement data with normal distribution were represented as (x)±s.Measurement data with skewed distribution were described as M (interquartile range).Survival rate was caculated by the Kaplan-Meier method.Results (1) Surgical and postoperative recovery situations:all 94 patients received successful operations,without perioperative death,including 73undergoing non-anatomical hepatectomy and 21 undergoing anatomical hepatectomy.Fourteen patients had conversion to open surgery and 27 received hepatic inflow occlusion.The median operation time,median volume of intraoperative blood loss and cases with intraoperative blood transfusion were respectively 187.5 minutes (75.0minutes),200 mL (200 mL) and 15.Eighteen patients had postoperative complications,including 6 with pleural effusion,6 with abdominal effusion,1 with wound infection,1 with abdominal infection,1 with venous thrombosis,1 with bleeding,1 with coagulation disorders and 1 with hepatic insufficiency.Clavien-Dindo classification of complications:11,1,5 and 1 patients were detected in grade Ⅰ,lⅡ,Ⅲ and Ⅳ,respectively.All complications were improved by symptomatic treatment.The median duration of hospital stay was 7 days (6 days).(2) Postoperative pathological examination:results of tumor pathological examination showed that 45,5,9 and 35 patients were respectively confirmed as hepatocellular carcinoma,cholangiocarcinoma,metastatic hepatic carcinoma and benign liver tumor.(3) Follow-up and survival situation:59 patients with malignant tumors were followed up for 6.0-52.0 months,with a median time of 42.6 months.Postoperative 1-and 3-year overall survival rates of 59 patients with malignant tumors were 98.3％ and 84.7％,respectively.Conclusions LH for segment Ⅶ and Ⅷ liver tumors which is conducted in experienced medical center is safe and feasible,with definite effects.Building operating space for operation under laparoscopy,determining precise positioning of the tumor and plane of liver resection,and selecting proper instruments of liver partition and techniques of hepatic inflow occlusion are the key points of successful operation.

Objective To compare the clinical characteristics and influence factors of hyperuricemia between genders,in order to provide references for better controlling and preventing the occurrence and development of hyperuricemiaprovide.Methods A total of 5 783 people who underwent physical examination in two Baoding Health Screening Centers from January 1st to June 1st,2016 were enrolled in this study,and all volunteers completed physical examination,laboratory examination and questionnaire survey.Patients with hyperuricemia were selected to analyse the clinical characteristics and influence factors.Results There were statistically significant differences in clinical characteristics,including obesity,blood pressure,blood glucose,blood lipids,liver function,renal function,anemia,blood rheology examination,thyroid ultrasound and lateral radiographs,between male and female patients with hyperuricemia (P＜0.05).The survey showed that there were statistically significant differences in age,education level,marital status,work status,sleeping status,smoking and drinking between male and female patients with hyperuricemia (P＜0.05).The red blood cells counts,marital status and education level were influence factors for female patients with hyperuricemia,while have little effect on male patients.The smoking,creatinine and diastolic blood pressure were influence factors for male patients with hyperuricemia,while have no effect on female patients.Conclusion The clinical characteristics and the influencing factors of male and female patients with hyperuricemia are different,so corresponding preventive and therapeutic measures should be taken for male and female patients.

Objective To study the optimal timing of preoperative injection of indocyanine green in laparoscopic liver tumor resection under indocyanine green fluorescent navigation to obtain the most satisfactory fluorescence imaging effects.Methods 60 patients with liver tumors who underwent laparoscopic hepatectomy from April 2017 to October 2018 were retrospectively studied on the intraoperative fluorescence imaging effects.A simple grading of the fluorescence imaging effects was developed.The ICG R15 and preoperative injection times of ICG were correlated with the intraoperative fluorescence imaging effects.Results Of 60 patients with liver tumors,59 patients underwent laparoscopic liver resection and one patient was converted to open surgery.The overall satisfaction rate of intraoperative fluorescence imaging was 73.4％ (44/60).In the patients with an ICG R15 rate ≤ 7％,it was easier to obtain good fluorescence imagings when the preoperative administration time was longer than 48 hours.Even when the preoperative administration time was longer than 5 days,satisfactory fluorescence imaging effect could still be obtained in these patients.In the patients with an ICG R15 rate ＞ 7％,intraoperative fluorescence imagings were unsatisfactory when the administration time was less than 6 days.Relative better imagings were obtained in these patients when the preoperative administration time was more than 6 days.Conclusions When the pre-operative ICG injection dose was not changed,the preoperative administration time should be adjusted according to the value of the ICG R15 to obtain better intraoperative fluorescence imaging effects of the liver tumors.The optimal timing needs to be further studied by a large case study.

Cervical cancer is the leading cause of cancer death in women in the developing countries.The treatment based on surgery,radiotherapy and chemotherapy is often accompanied by intolerable complications.Clinical practice has proved that TCM therapy has a positive effect on the complications related to the treatment of cervical cancer,but there is still a lack of scientific and standardized application reference opinions.Based on Delphi method,our research group constructed and formulated an expert consensus study on the complications related to the treatment of cervical cancer with TCM therapies,so as to provide a reference for clinical treatment of such diseases.
