Objective To optimize the extraction conditions of Hyperici Perforate Herba, Coptidis Rhizoma, Schisandrae Chinensis Fructus, and Ziziphi Spinosae Semen forJinzao Yuanzhi Capsule.Methods Hyperin extraction rate was set as index, and HPLC was used for determination. The extraction conditions of ethanol concentration, ethanol quantity, extraction time and other factors were studied with orthogonal test and comparative test.Results Ethanol concentration and extracting times were remarkable factors in the test. The optimum extraction technology forJinzao Yuanzhi Capsule was to reflux and extract the materials with 8 times of 70% ethanol for 2 times, reflux extraction for 1.5 hours, filtration. Then 6 times of 70% ethanol was added for 1.5 hours’ reflux, filtering, and merging extracted liquid.Conclusion The optimum extraction technology is reasonable and feasible.

Objective To investigate the effect of psychological abuse in childhood on the personality of undergraduates with depression as well as its possible mechanism, and thus provide scientific evidence for the intervention of depression in undergraduates. Methods Particinants were 733 undergraduates from a university in Henan Province. They were surveyed with Center for Epidemiological Studies-Depression scale (CES-D), childhood experience of care and abuse questionnaire (CECA. Q) and Eysenck personality theory (EPQ). Results the correlation between maternal antipathy and introversion-extroversion of personality;psychological abuse in childhood had apparently positive correlation with the depression in undergraduates (r = 0. 257, r = 0. 304, r =0. 243, P＜ 0. 01) and that of childhood maternal neglect to psychoticism (β = 0.206, P＜ 0.01) were positive and significant. The standard regression coefficients of paternal neglect to introversion-extroversion (β= -0. 143, P＜0. 01)were negative and significant . The scores of childhood paternal antipathy and maternal antipathy explained that childhood paternal antipathy had indirect effect via adulthood neuroticism on the depression in undergraduates,furthermore, the indirect effect demonstrated 59.8% of the total effect. Conclusion This study suggests that the personality of undergraduates with depression is affected directly by psychological abuse in childhood, and adulthood personality may mediate the relation between childhood psychological abuse and adulthood depression.

Objective To investigate the association between drainage volume and removal of chest tube after video-as?sisted thoracoscopic surgery(VATS) lobectomy. Methods Patients with VATS were randomly divided into three groups:the drainage volume was less than 100 mL/24 h (group A), the drainage volume was more than 100 mL/24 h but less than 200 mL/24 h(group B) and the drainage volume was more than 200 mL/24 h but less than 300 mL/24 h (group C). According to in?clusion criteria and exclusion criteria, finally there were 90 patients in group A, 87 patients in group B and 83 patients in group C. The duration of chest-tube drainage, the occurrence of pulmonary infection, pulmonary atelectasis, pneumothorax, hydrothorax, seepage or delayed union after removal of chest tube, the dosage of analgesic and the length of hospital stay af?ter surgery were recorded. Data were analyzed statistically. Results The average durations of chest-tube drainage were (91.76±15.59)h, (84.17±18.33)h and (56.14±12.25)h, the average morphine consumptions were (236.82±67.20)mg, (187.36± 76.64)mg and (139.29±52.74)mg, and the average lengths of hospital stay after surgery were (11.47±1.90)d, (10.68±2.50)d and (10.23 ± 2.14)d for three groups of patients, respectively. And the indexes in group C were distinctly lower than those in group A and group B (P<0.05). There were no significant differences in pulmonary atelectasis, the occurrence of postopera?tive pulmonary infection, pneumothorax, hydrothorax, seepage or delayed union after removal of chest tubes between three groups of patients (P > 0.05). Conclusion It is safe and acceptable that the removal of chest tube after VATS when the drainage volume reaches 300 mL within 24 h.

Objective To evaluate comprehensively the effectiveness of transitional care for patients with diabetic in china. Methods Cochrane Handbook for systematic reviews of interventions was followed,and strictly designed search strategies,pub-lished literatures were searched through Chinese biomedical literature database(CBM),Wanfang,CNKI,VIP database.These data-bases were searched to collect the randomized controlled trials of transitional care for patients with diabetic in China.The retrieval time was limited from 2000 to 2014,All the literatures were selected according to the strictly designed strategies .A Meta analysis was performed by RevMan5.0 software.Results Totally 8 trials were included.Meta analysis showed that 6 months after the in-tervention,the continuing nursing and the control group in the incidence of complications of hypoglycemia had no significant differ-ence[RR= 0.69,95%CI (0.21,2.27 ),P = 0.540 ],while fasting glucose had significant difference [WMD = - 1.54,95%CI (-2.89,-0.1 9),P =0.030].12 months after the intervention,the continuing nursing and control groups in the incidence of com-plications of hypoglycemia [RR = 0.34,95%CI (0.1 6,0.72 ),P = 0.005 ],in fasting plasma glucose [WMD = - 1.03,95%CI (-2.78,0.72),P =0.250],in glycated hemoglobin [WMD =-1.73,95%CI (-2.43,-1.04),P <0.01]had significantly differ-ence.18 months after the intervention,the continuing nursing and control groups in the incidence of complications of hypoglycemia were significantly different[RR=0.28,95%CI (0.12,0.67 ),P = 0.004].Conclusion Transitional care intervention on patients with diabetes can reduce fasting blood glucose,glycated hemoglobin,and the incidence of complications,but the complications of in-tervention time should be greater than 6 months.

Objective To evaluate the diagnostic value of multi-slice computed tomography (MSCT)for incisional hernia of ab-dominal wall before operations.Methods Thirty patients with incisional hernia in abdominal wall confirmed by the pathology were enrolled in this study.All patients underwent MSCT examination with sagittal and coronal MPRs,and 21 cases underwent ultra-sound (US)examinations.The value of transverse scan and MPRs & MSCT and US on demonstrating the number,location,con-tents of incisional hernia,and accompanying intestinal obstruction or other complications were retrospectively evaluated and com-paired.Results Of 30 cases,there were 40 hernias,the rate of MSCT and US in detecting incisional hernias were 97.5% and 56.0%, respectively.MSCT performed better than US on demonstrating the incisional hernias (P =0.000).On MSCT,there was no signif-icant difference in the detection for isolated incisional hernia between the MPRs and axial scans (P = 1.000 ).However,MPR showed a more accurate rate for two or multiple incisional hernias diagnosis (P =0.006),and the sagittal reconstruction displayed more correct than coronal reconstruction on two or multiple incisional hernias (P =0.01 9).Furthermore,MSCT can exactly reveal the complications of incisional hernias (7 cases of intestinal obstruction,5 cases of intestinal ischemia and edema,and 1 case of me-tastasis in incisional hernia),which were not detected by US.Conclusion MSCT can correctly demonstrate the incisional hernia of abdominal wall and its complication,it can provide important imaging reference for clinical therapy.

Objective: To observe the effect of Tongxinluo (TXL) on homocysteine-induced rat’s cardiac micro vascular endothelial cell (RCMECs) injury and to study the oxidative stress mechanism. Methods: Primary RCMECs were cultured with tissue explants process, cell morphology was observed by inverted microscope and the cell was identiifed by CD31 immunolfuorescence method. RCMEC injury model was established by Homocysteine (Hcy) induction and the cells were divided into 5 groups: Control group, with normal cells, Hcy group, the cells were treated by Hcy at 10 mmol/L, Low-dose TXL group, Hcy treated cells were cultured with TXL at 100 mg/L, Middle-dose TXL (200 mg/L) group and high-dose TXL (400 mg/L) group. Cell survival rates were detected, supernatant levels of superoxide dismutase (SOD) activity and malondialdehyde (MDA) content were examined, intracellular protein expressions of reactive oxygen species (ROS) and endothelial nitric oxide synthase (eNOS) were detected and mRNA expression of endothelin-1 (ET-1) was measured in different groups respectively. Results: Compared with Control group, Hcy group showed decreased cell survival rate (74.61 ± 2.88)% vs (100.00 ± 2.07)%, increased supernatant level of MDA (4.10 ± 0.18) nmol/ml vs (1.92 ± 0.10) nmol/ml, reduced SOD activity (7.55 ± 0.71) U/ml vs (20.77 ± 0.68) U/ml, elevated ROS level(38.17 ± 10.28) % vs (19.83 ± 2.97) %, up-regulated mRNA expression of ET-1 and down-regulated protein expression of eNOS. Compared with Hcy group, the above indexes were improved in each TXL group at different levels. Conclusion: TXL could decrease Hcy induced RCMECs injury, such protection was conducted by reducing the oxidative stress mechanism in cells.

OBJECTIVE To find the infla mmation bio markers induced by coke oven e missions (COE),we investigated the changes of T helper 17 (Th17 )cytokines in hu man bronchial epithelial (16HBE)cells.METHODS 16HBE cells were exposed to organic extracts of COE collected fro m co-king plant at the concentrations of 5,10 and 20 mg·L -1 for 24 h or 5 d to establish short-term and long-term cell models,respectively.Cell viability was measured by MTT assay and infla mmatory da mage was assessed by lactate dehydrogenase assay (LDH).The cytokines in culture supernatant sa mples was detected by co mmercial hu man Th17 cytokine panel kit.RESULTS COE Can induce infla mmation in COE 20 mg·L -1 group and no expression on IL-17 F and IL-1 β.The concentration of IL-10 was 1 .25 ± 0.54,1 .39 ±0.13 and (1 .90 ±0.73)pg·mL -1 in COE 5,10 and 20 mg·L -1 group showing good con-centration-effect relationship (r=0.98,P <0.05 ).IL-23 expression was found only higher at 10 and 20 mg·L -1 and the concentrations were 3.38 ±3.90 and (1 .74 ±2.00 )pg·mL -1 ,respectively.In 16HBE cells treated by COE for 5 d,elevated expression of IL-17A was found in COE 5 and 10 mg·L -1 group,and there was statistically sigificant difference between COE 10 mg·L -1 and DMSO group (P<0.05).Elevated concentration of IL-17F of 10.2 ±1 1 .78 and (6.79 ±7.84)pg·mL -1 was found in COE 5 and 10 mg·L -1 group.The concentration of IL-10 was 1 .71 ±0.02,1 .49 ±0.25 and (2.82 ± 0.33)pg·mL -1 in COE 5,10 and 20 mg·L -1 group,respectively.We found increased IL-1 βexpression with concentration of 2.72 ±0.62,2.25 ±0.33 and (0.93 ±0.21 )pg·mL -1 in COE 5,10 and 20 mg·L -1 group with negative dose-response relationship.We also found more elevated TNF-αlevels in the 5 d than in the 24 h model with no COE specific relationship.CONCLUSION COE induces expression changes of Th17 cytokines profile in 16HBE cells,including IL-23 and IL-1 βfor early and long-term infla mmation,respectively.IL-10 may be a candidate marker for population study on COE induced infla mmatory injury.

Objective To investigate the clinical value of prenatal MRI in the diagnosis of fetal bowel obstruction.Methods Pregnant women suspected to have fetal abdominal abnormalities by ultrasonography were suggested to undergo MRI examinations within two days.Scanning sequence included FIESTA,SSFSE and T1WI SPGR sequence,with field of view focused on the fetal abdomen.After the final diagnoses of the cases were obtained by induced labor pathological examination or postpartum imaging or operation,the imaging data and the clinical data were reviewed and analyzed retrospectively.Results A total of 23 cases with bowel obstruction were included in the study.Four fetuses with duodenal atresia showed low T1 signal,high T2 signal characterized by double-bubble sign on MRI.There were 10 fetuses with jejunoileal atresia,showing bowel dilatation and hyperintense micro-colon on T1WI.Five cases of them depicted expansion of the terminal ileum with high T1 meconium signal.One each fetus had colonic atresia,intestinal malrotation with double-bubble and whirl sign.Annular pancreas with double-bubble sign and pressure trace of the bracket shape was detected in 3 fetuses.Meconium peritonitis was present in 4 fetuses,with 2 of them showing dilatation of intestine,ascites and pseudocysts.Conclusions According to the signal characteristics of amniotic fluid and meconium in the gastrointestinal tract on MRI,the obstructive level and development status of the distal bowel can be determined with MRI.It can provide additional information to ultrasonography,which brings clinical significance to prenatal diagnosis and intrapartum surgical operation.

Objective To investigate the effect of all-trans retinoic acid(atRA) on the urinary TGF?_1 excretion and glomerular lesion of diabetic rats at early stage.Methods SD rats were randomly assigned into 3 groups: atRA treated group,diabetic control group and normal control group.Streptozotocin(STZ)-induced early diabetic male SD rat were used.The atRA treated group were treated with daily subcutaneous injections atRA of 10mg/kg for 7 days(n=6),and then the excretion of urinary protein and TGF?_1 and NO level of plasma,urine and renal tissue were measured,and pathological changes of their kidneys were observed.Results The diabetic control rats showed increased urinary excretion of protein and TGF?_1 and NO level of plasma,urine and renal tissue and deposit of glomerular matrix,while atRA prevented these changes.Conclusion AtRA can prevent the development of diabetic nephropathy,which is relevant with the inhibition of secretion of TGF?_1 and NO.

Objective To investigate the abnormal functional connectivity (FC) between the substantia nigra (SN) and the brain motor area in rapid eye movement sleep behavior disorder (RBD) by Unified Parkinson′s Disease Rating Scale (UPDRS), Hoehn-Yahr Scale and resting state functional magnetic resonance imaging (rfMRI).Methods A total of 34 subjects (14 with RBD (RBD group), 12 with Parkinson′s disease (PD group), and 8 age, sex-matched normal controls (control group)) recruited in the Department of Neurology, Henan Provincial People′s Hospital from 2014 to 2015 were enrolled in this study according to international diagnosis criteria.All subjects were examined by UPDRS, Hoehn-Yahr Scale and rfMRI.Results UPDRS scores and Hoehn-Yahr staging were 0.00 (0.00, 3.75) and 0.00 (0.00, 0.50) respectively in the RBD group, which were significantly different from that in the PD group (30.5 (18.75, 33.00) and 1.75 (1.50, 2.50), respectively;Z=-3.782, P<0.05 and Z=-2.963, P<0.05), whereas not significantly different from that in the control group (0.00 (0.00, 0.00),0.00 (0.00, 0.00), respectively;Z=1.16, P>0.05 and Z=1.10, P>0.05).The FC analysis showed alterations from the right SN to bilateral cerebellum respectively among the three groups (Fright cerebellum=12.975, Fleft cerebellum=6.144;P<0.05);furthermore, there were significant increases in the RBD group compared with the PD group (t=-4.602,-5.080, P<0.005).The FC analysis showed reduced correlation from the right SN to the left prefrontal cortex in the RBD and the PD groups compared with the control group (t=-4.899,-3.500, P<0.005), but there was no statistically significant difference between the RBD and the PD groups (t=2.035, P>0.05).Conclusions There was abnormal FC from the SN to motor areas in RBD patients, and partial alterations were similar as PD patients.rfMRI provided an evidence that RBD might be presymptom of PD.
