Objective To study the effects of oligohydramnios in full-term pregnancy women deliveried on the perinatal outcomes.Methods 320 suspected oligohydramnios cases from January 2008 to June 2009 were taken as observation group,and compared with 320 cases full-term pregnant women with normal amniotic fluid and without any high-risk factors as control group.B-type ultras onography was used to determine the volume and index of amniotic fluid and fetal umbilical blood flow index (S/D).Blood estriol was determined combining with non-stress test(NST)and oxytocin challenge test(OCT) or contraction stress test(CST) examination to evaluate maternal and fetal situation.The perinatal outcomes of the two groups was analyzed and compared.Result The neonatal asphyxiation and mortality rate between the two groups had no significant difference( P ＞ 0.05).The rate of cesarean section in the observation group was increased( P＜ 0.05).Conclusion The term pregnancy women with oligohydramnion during labour diagnosed by B-type ultrasonography should select vaginal delivery based on comprehensive examination.

Objective To evaluate the clinical value of pulmonary embolism severity index (PESI) in non high-risk acute pulmonary thromboembolism (APTE) patients treated with sequential anticoagulation.Methods Non high-risk APTE patients treated with sequential anticoagulation were divided into two groups according to PESI:high-value group and low-value group.Prognosis and treatment response was compared between two groups.Results There were 82 cases in high-value group,and 76 cases in low-value group.The rate of adverse events in high-value group was significantly higher than that in low-value group [23.2％(19/82) vs.7.9％ (6/76)] (x2 =5.0698,P =0.009),and 30 days cumulative hazard was also significantly higher than that in low-value group (P ＜ 0.05).The sensitivity of predicting adverse events by PESI was 76.0％,specificity was 52.6％,positive predicting value was 64.6％,and negative predicting value was 65.9％.The mortality in high-value group was significantly higher than that in low-value group [9.8％(8/82) vs.1.3％ (1/76)] (P =0.022).After 30 days of anticoagulation,the pulmonary artery systolic pressure,internal diameter of right ventricle in high-value group was significantly higher than that in low-value group [(39.4 ± 8.1) mm Hg (1 mm Hg =0.133 kPa) vs.(27.2 ± 5.5) mm Hg,(33.0 ± 7.8) mm vs.(21.7 ± 4.6) mm] (P =0.034,0.021),and arterial oxygen partial pressure was significantly lower than that in low-value group[(75.15 ± 12.41) mm Hg vs.(86.36 ± 9.22) mm Hg](P=0.016).Conclusions PESI can effectively predict short-term prognosis of non high-risk APTE patients treated with sequential anticoagulation.At least some of these patients might need treatment other than sequential anticoagulation.

[ABSTRACT]AIM:Toinvestigatetheapplicabilityanddegradabilityoftheantigen-extractedxenogeneicbone carrying recombinant human bone morphogenetic protein 2 ( rhBMP-2) as a scaffold in repairing the mandibular defect in vivo.METHODS:New Zealand rabbits (n=28) with 28 mandibular defects were divided into 3 groups at random:anti-gen-extracted xenogeneic cancellous bone /rhBMP-2 group (group A), antigen-extracted xenogeneic cancellous bone group ( group B ) and blank control group ( group C ) .Twelve bone defects each in group A and group B were classified into 3 time points (4, 8 and 12 weeks).Observation in general, X-ray test and hematoxylin and eosin staining and bone density measurement were conducted on each rabbit in group A and group B .Four bone defects were classified into group C .Ob-servation in general , X-ray test and hematoxylin and eosin staining were also conducted on each rabbit in group C .RE-SULTS:The X-ray showed that the implanted materials were degraded after a period of time , and were replaced by autoge-nous bone.At the 12th week, the implanted materials in group A were entirely degraded and replaced by autogenous bone . The bone density measurement showed that the bone density was enhanced after implantation .At the 12th week, there was an obvious difference between group A and group B .The hematoxylin and eosin staining showed there were more neovascu-larization, new fibrosis and new bone formation in group A than those in group B .The implanted material in group A de-graded much faster than that in group B .The significant difference in the new bone area ratio between the 2 groups among all weeks was observed .CONCLUSION: An antigen-extracted xenogeneic cancellous bone has good biocompatibility , which can act as a scaffold in bone repairment .It is the carrier of rhBMP-2 to continue the bone formation .Therefore, anti-gen-extracted xenogeneic cancellous bone is a kind of good material for bone repairment .

A 57-year-old female patient was admitted to our hospital because of sustained hyponatremia within stress dose of hydrocortisone replacement after transsphenoidal partial pituitary tumor surgery. Multiple clinical parameters investigation for 2 weeks was shown increasing serum Na+and uric acid level and decreasing blood pressure level under water restriction about 500 ml/d, and even without hydrocortisone replacement, the serum Na+ still maintain normal level. After surgeries and radiotherapy, the tumor was undetectable and serum Na+ level was within the normal range without any water restriction.

Objective To evaluate the efficacy and safety of treating liver cancer using 131I-anti-CD147-monoclonal-antibody (131I-anti- CD147-McAb) by transcatheter hepatic arterial infusion (TAI) in a rabbit liver cancer model. Methods Forty-five rabbit models were randomly divided into three groups evenly. Transcatheter hepatic artery infusion under general anesthesia were performed in all three groups. Group A:control group, saline. Group B:pure 131I solution. Group C: 131I-anti-CD147-McAb solution. About 2 ml blood sample was obtained from all rabbits for liver, kidney,and thyroid function at pre-TAI and post-TAI 1 day, 3 days ,7 days, 14 days, 21 days. The rabbits were scanned by single photon emission computed tomographic (SPECT) to monitor radionuclide bio-distribution and tumor size on 1 day, 7 days, 14 days, 21days after procedures in group B and C. On 14 days after procedure, five rabbits were randomly selected to be sacrificed in each group for pathological and immunological investigations. The remaining rabbits continued to be fed, and survival rates were measured. Results The TAI and SPECT-CT/CT procedures were successfully performed in all rabbits. Test results showed that AST and ALT levels tended to increase transiently 1 day after TAI (P<0.05). The liver function returned to pre-operative levels (P> 0.05) 7 days after TAI. FT3 and FT4 mean values of rabbits in group B and C continued to decline 7 days after TAI, while thyroid stimulating hormone (TSH) showed corresponding increase (P<0.05). WBC mean value of rabbits in group B and C declined slightly after procedures (P>0.05). SPEC-CT imaging of rabbits shows that most of the radionuclide was gathered in the gastrointestinal tract and thyroid in Group B, however, radionuclide was mainly concentrated in the tumor lesions in Group C. Fourteen days after procedures, radionuclide imaging of all rabbits disappeared in group B and C. The VX2 liver tumors increased rapidly after treatment in group A and B;but the tumors gradually reduced their size in group C. At 14 days after TAI: The proportion of tumor necrosis in group C was significantly greater than that in groups A and B (P<0.05). The microvessel density (MVD) number of residual tumor in group C was less than groups A or B (P<0.05).TUNEL analysis suggested that more apoptosis bodies was displayed in the residual tumor tissue in group C than that in groups A and B, but the expression of MMP-2 and vessel endothelial grouth factor (VEGF) was significantly reduced in group C than group A and group B. Median survival time of the rabbits in groups A, B, C was 22 days, 26 days and 54 days respectively. Survival time of the rabbits in group C was significantly prolonged than other two groups (P<0.01). Conclusions Radioimmunotherapy with 131I-anti-CD147-McAb by TAI can inhibit the growth and metastasis of liver cancer, and prolong the survival of experimental animals. The method is effective and safe in this animal study.

Objective To investigate the effect of formative assessment on skill acquisition of basic life support (BLS) among medical students. Methods Totally 206 undergraduates were ran-domized into control group (C group) and interventional group (F group). A BLS lecture was given in both groups. And then, 45 min BLS training and BLS skill assessment (after training) were given in C group. Undergraduates in F group received BLS skill assessment (formative assessment) before training, and 15 min feedback was delivered based on the assessment, then 30 min BLS training was conducted. Skills assessment was conducted again in F group after the training. Student's-t-test was used to compare the difference of skills between the two groups and P<0.05 signifies statistically sig-nificant differences. Results Score of F group (85.2±7.3) were higher than that in C group (68.2± 13.2), with statistical difference. Conclusion A formative assessment could significantly improve skill acquisition of BLS among medical students.

Objective To analyze copy number variance (CNV) in whole genome by using gene chip technology, and to screen the radiosensitivity associated genes on esophageal squamous cell carcinoma (ESCC). Methods The patients with ESCC who received radiotherapy alone in Anyang Tumor Hospital from December 2013 to August 2016 were selected, and biopsy paraffin samples were preserved in the center of pathology. The patients were divided into radiosensitivity group (group S) and radio-resistance group (group R). DNA was extracted from these paraffin samples in both groups. Whole human genome CNV was detected by using genechip from OncoScan Array platform designed by Affymetrix company, and the differences of gene segments were screened in the two groups. Results Nineteen samples of ESCC patients were collected to extract DNA in this study. To balance pair analysis in the two groups, 10 samples were selected from the qualified patients, including 5 cases in group S and 5 cases in group R respectively. There were no statistical differences in gender, age, lesion site, lesion length, radiation dose of the two groups (all P> 0.05). Loss of heterozygosity (LOH) was the main type of CNV. The analysis results showed that LOH in q24.32-q24.33 of chromosome 10 and LOH in q21.2-q21.31 of chromosome 18 had high frequencies (100 ％) in group R, however, none were detected in group S. LOH in q27-q28.1 of chromosome 4 had a high frequency (80％) in group S , however, none were detected in group R. Conclusion LOH in 10q/18q is related to radio-resistance in ESCC, and LOH in 4p is associated with radiosensitivity in ESCC.

Objective:To explore the difference of perceptual processing in ERP between cartoon faces and real faces.Methods:Thirty college students were selected and adopted the face recognition paradigm.The independent variables were face type (real, cartoon) and emotional type (positive, neutral, negative). The dependent variables were response time and the amplitude and latency of ERP data.SPSS 22.0 software was used for repeated measurement analysis of variance.Results:The reaction time of cartoon expression ((455.58±55.18)ms) was shorter than that of real face ((471.49±63.02)ms) of college students.There was no significant difference in N170 amplitude and latency among different faces and expressions(all P>0.05). The vertex positive potential VPP latency of positive real faces ((159.89±13.93)ms) was shorter than that of positive cartoon faces ((165.68±14.35)ms) ( PVPP<0.05). It was easily affected by perceptual load, but negative emotion was not affected by it.In the late processing stage of late positive potential(LPP), the amplitude of positive emotional real face ((10.4±1.22)μV) was higher than that of cartoon ((4.26±0.53)μV), and that of negative emotional cartoon face ((3.84±0.36)μV) was higher than that of real face ((1.9±0.24)μV) ( PLPP<0.05). Conclusion:There are no differences in early stage N170, and the late processing stage, the real faces have an overall advantageous effect on positive emotion, and the local characteristics of negative emotional cartridge wells are more superior.
