A co-words network for high frequency words was established using the title information of papers pub-lished in 22 medical journals from 2005 to 2013.The evolution of medical scientific research topics was analyzed with the visual analysis software NEViewer, which showed that medical research in China was focused on basic and application studies with the prevention and treatment of frequently encountered diseases and the associated technical methods as the two main directions, and that medical scientific research topics would remain their stable status in a rather long period.The hot medical topics were explained.

Objective:To investigate the impact of Puerarin on oxidative stress in patients undergoing continuous ambulatory peritoneal dialysis(CAPD).Methods: Thirty-eight patients CAPD were randomly divided into two groups,an experimental group(n=19) receiving peritoneal dialysis fluid containing Puerarin(50 mg/2L) in vivo for two weeks and a control group(n=19) receiving dialysis fluid without Puerarin.The concentrations of oxidative stress markers in the serum and effluent such as glutathione(GSH),total-superoxide dismutase(T-SOD),malondialdehyde(MDA),Kt/V and creatinine clearance rate of the two groups(Ccr) were measured and compared before and after the treatment.Results: After the treatment,the concentrations of GSH and T-SOD in the serum and effluent were significantly higher(P

Objective:to find personality traits of violent offenders with schizophrenia Method:31 violent offenders with schizophrenia and 55 schizophrenic patients without criminal record were applied MMPI Result: the Hs, D, Hy, Pa and Si subscores in violent offenders were significantly higher than the counterparts of regular schizophrenic patients Conclusion:personality traits of schizophrenic violent offenders are different from regular patients with the same disorder

Objective To investigate the correlations of plasma total homocysteine (tHcy) level and the C677T methylene tetrahydrofolate reductase (MTHFR) polymorphism with vascular dementia (VaD) and Alzheimer's disease (AD).Methods A case control study in 64 AD patients (AD group),72 VaD patients (VaD group) and 56 healthy controls (control group) was under taken.Plasma tHcy level was determined by enzymatic cycling assay.The MTHFR677C/T polymorphism was analyzed by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP).Results tHcy levels were significantly higher in AD and VaD groups than in control subjects(P＜ 0.05).VaD patients also showed increased levels of tHcy as compared to AD patieuts,but no statistic significance was found(P＞0.05).Logistic regression analysis indicated that tHcy level was a risk factor for dementia (including AD and VaD together)[(OR=1.15),VaD (OR=1.23),AD (OR=1.328)].MTHFR677 TT genotype represented higher plasma tHcy concentrations than CC and CT genotypes(both P＜0.05).The distribution frequency of the T allele of MTHFRC677T was 45.3 ％ (58/128)in AD group,49.0％(51/104)in VaD group and 33.0％(37/112)in control group,and it had significant differences between the three groups (P＜0.05).There was a significant difference in distribution frequency of the T allele of MTHFRC677T between VaD and control group (P＜0.01).The distribution frequency of MTHFR677 genotype (CC/CT/TT) had a significantly difference between the VaD group and the control group(P＜0.01).Conclusions High plasma level of tHcy is closely correlated with AD and VaD.tHcy level is the risk factor for dementia (including AD and VaD together).The polymorphism of MTHFR677C/T affects the plasma tHcy level.The T allele of MTHFRC677T may correlate with VaD,while has no direct correlation with AD.

Liver failure is a clinical syndrome characterized by serious liver damages.It can results from a variety of causes,and the prognosis is usually poor.How to objectively assess the severity of liver failure and accurately predict the prognosis are the hot spots and challenges in studies on liver failure.The assessment criteria and models widely used clinically include:Child-Turotte-Pugh (CTP) score,acute physiology,age and chronic health evaluation(APACHE) Ⅱ/Ⅲ score,King's College Hospital (KCH) criteria,sequential organ failure assessment (SOFA) score and model for end-stage liver disease (MELD) score.Besides,more factors are identified as potential markers in prognosis assessment.This paper reviews the importance of prognosis assessment in liver failure,and introduces current and new systems or markers in prognosis assessment.

Objective To evaluate the model for end-stage liver disease (MELD) and MELD combined with serum natrium level (MELD-Na) in predicting short-term prognosis of liver failure.Methods Clinical data of 322 patients with liver failure admitted in the First Affiliated Hospital of Xinjiang Medical University from April 2003 to April 2012 were retrospectively analyzed.MELD and MELD-Na scores were calculated at diagnosis and one week after the diagnosis,and then △MELD and △MELD-Na were determined.Receiver operating characteristics (ROC) curve and Kaplan-Meier survival curve were used to evaluate the value of the above scores in predicting 3-month prognosis.Results The 3-month mortality rates of acute/sub-acute,acute-on-chronic and chronic liver failure were 77.4％ (24/31),41.7％ (50/120) and 56.1％ (96/171),respectively,and the difference was of statistical significance (x2 =14.273,P ＜0.01).For acute/sub-acute liver failure,the areas under ROC curve (AUCs) were 0.699-0.836 for each scoring system in predicting short-term prognosis,and no significant difference was observed (Z =0.507,0.622,0.712,0.727,0.779 and 0.599,P ＞0.05).For acute-on-chronic liver failure,AUCs were 0.889 and 0.897 for △MELD and △MELD-Na in predicting short-term prognosis,which were higher than those of MELD and MELD-Na scores at the baseline (Z =3.110 and 3.500,P ＜ 0.05),but no significant difference was observed between △MELD and △MELD-Na (Z =0.310,P ＞ 0.05) ; Kaplan-Meier survival curve showed that the 3-month mortality rate for patients with △MELD ＞ 3.5 was 87.8％,and the average survival time was 34.05 d.For chronic liver failure,AUC of △MELD was 0.871 in predicting short-term prognosis,which was higher than that of △MELD-Na (Z =4.229,P ＜0.05) ; Kaplan-Meier survival curve showed that the 3-month mortality rate for patients with △MELD ＞ 4.5 was 89.9％,and the average survival time was 29.08 d.Conclusion For acute/sub-acute liver failure,MELD,MELD-Na,△MELD and △MELD-Na are all satisfactory in predicting short-term prognosis; for acute-on-chronic liver failure,△MELD and △MELD-Na are better than MELD,MELD-Na scores at the baseline; and for chronic liver failure,△MELD is the best indicator.

Objective To investigate the feasibility and clinical value of double-balloon endoscopy in subjects of failed conventional colonoseopy and gastro-intestinal tract modified surgery.Methods Doubleballoon endoscopy was performed in thirty-two subjects of failed conventional colonoscopy,three and nine patients of previous subtotal gastrectomy with BillrothⅡand gastro-intestinal modified surgery for various clinical manifestations.Suceessful intubation rates of terminal ileum or cecum in colonoscopic failure patients,afferent and efferent loop intubation in patients of BillrothⅡand alimentary tract modified surgery,were recorded and diagnostic yields in these patients were also observed.Results The endoscopy was successfully intubated into terminal ileum or cecum in 29 subjects,the intubated rate was 90.6%,the endoscopic diagnosis was obtained in 7 subjects,and endoscopic treatment was performed in 3 subjects.The endoscopy was successfully inserted in terminus of afferent loop and 150-180 cm of efferent below the anastomosis in all 3 patients of Billroth type Ⅱ gastrectomy,and the diagnosis was all clarified.And endoscopic retrograde cholangiopancreatography was performed in one patient.Five of nine patients with previous alimentary tract modified surgery had lesions detected after endoscopic procedure,and double-balloon endoscopy could have a thorough visualization on operated area and suspected region as needed.Abdominal pain and melaena were observed in 8 and 3 subjects respectively.Transient urine amylase elevation was found in one patient.The symptoms were alleviated and amylase was returned to normal after treatment.Conclusions Double-balloon endoscopy was a safe and feasible remediai endoscopic procedure with high diagnostic yields and endotherapeutic interventional capability,in patients of failed conventional colonoscopy and previous BillrothⅡgastrectomy and alimentary modified surgery.
