OBJECTIVE:To explore the treatment effect and complication prevention of various stent materials for intracranial arteriostenosis.METHODS:A computer-based online search of Science Direct and Ei database (1998-01/2009-10) was performed for English articles with the key words of "intracranial arteriostenosis,stent placement" In addition,CNKI and CBM database (1998-01/2009-10) were searched for related Chinese articles with the same key words in Chinese.Moreover,related works were manually searched.Studies regarding various stent materials for intracranial arteriostenosis were included,including basic and clinical experiments.RESULTS:Multicenter studies of worldwide show that stent implantation displays obvious advantages in treating carotid artery stenosis compared with carotid endarterectomy.Recently,with developing of balloon and stent compliance,as well as stent technology,and application of various novel materials and cerebral protection device,stent has become a safe and effective therapy for intracranial arteriostenosis.However,complications following stent implantation,such as restenosis,ischemic stroke,cerebral hemorrhage hypertransfusion syndrome,and cerebral angiospasm,limit its application.CONCLUSION:The safety and efficacy of intracranial stent implantation remains validation of multicenter and perspective studies.High incidence of restenosis following stent implantation requires further improvement.

An analytical method of reversed phase high performance liquid chromatography (RP-HPLC) was developed for simultaneous determination of 5-hydroxymethylfurfural and nine phenolic compounds (including (+)-catechin, (-)-epicatechin, chlorogenic acid, rutin, caffeic acid, protocatechuic acid, syringic acid, ferulic acid and p-coumaric acid) in 20 min.Ten components were detected and separated successfully by Diamonsil C_(18) column (150 mm x4.6 mm, 5 μm) at wavelength of 280 nm and column temperature of 42 ℃, with acetonitrile and 3% acetic acid solution as the mobile phase in gradient elution.The resultant correlation coefficients of the ten compounds were between 0.9911 and 0.9995 with detection limit from 0.2 to 0.5 mg/L, the RSD less than 2.4% and the average recoveries from 89.4% to 98.3%.These experimental results demonstrate that 5-hydroxymethylfurfural and the nine phenolic compounds in different rice wine samples can be determined with the new method for practical uses.

Objective To research the association between the prognosis of Acinetobacter baumannii infection and drug resistance among patients in the intensive care unit( ICU). Methods Eighty-four patients with Acine tobacter baumannii infection from February 2003 to April 2009 in Peking University Shenzhen Hospital ICU were retrospectively analyzed and divided into alive group(59 patients) and dead group(25 patients) by using 30-day mortality. The impact of drug resistant Acinetobacter baumannii on mortality was assessed by binary logistic regression. Results The mortality of patients with Acinetobacter baumannii infection was related to age, haematological malignancy, the Chanson Comorbidity Index, APACHEII score, multidrug-resistant Acinetobacter baumannii ( MDRAB) , carbapenem-resistant Acinetobacter baumannii (CRAB ) , septic shock and antimicrobial inappropriate therapy by univariate analysis( P < 0.05). Binary logistic regression revealed that CRAB( OR = 3. 360,95%CI: 1. 563 ～7.223,P< 0.05)and the Charison Comorbidity Index( OR = 1. 633,95% CI: 1. 201 ～2. 221 ,P <0.05) were independent risk factors. Conclusions The prognosis of Acinetobacter baumannii infection was closely correlated with drug resistance. The patients with CRAB infection had a higher mortality.

Reflux is a common post-gastrectomy complication due to the destruction of physiological antireflux mechanism,which affects patients' post-surgery life quality greatly.It's one of the basic requirements of digestive tract reconstruction to reduce the incidence of post-surgery reflux,and nowadays there are many kinds of anti-reflux surgical methods,which are also hot topics both at home and abroad.The non-surgical anti-reflux treatments are mainly focused on gastrointestinal motility promotion,mucosa protection,acid suppression,and so on.There are still some controversies concerned with which surgical or non-surgical way to choose.It's of great significance to have a deep insight into the associated mechanisms and make a wise decision on the surgical management with proper non-surgical assistance.

Objective To investigate the risk factors of post-pancreaticoduodenectomy complications.Methods The clinical data of 207 patients with pancreatic carcinoma or peri-ampullary carcinoma who underwent pancreaticoduodenectomy at the Anhui Provincial Hospital from Dec.2007 to Dec.2012 were studied.Seventeen clinicopathologic factors to correlate with the postoperative mortality and methods were selected for univariate analysis and multivariate analysis using logistic regression.Results Univariate analysis showed the major risk factors of postoperative mortality and morbidity were a history of previous operation,pre-operative drainage,total serum bilirubin level,alanine aminotransferase level,serum albumin level,serum pre-albumin level,parenchyma texture and pancreatic duct diameter (P＜0.05).Multivariate analysis showed alanine aminotransferase level,parenchyma texture and pancreatic duct diameter were independent risk factors of postoperative complications.Pancreatic duct diameter was the independent risk factor of pancreatic fistula.Pancreatic fistula was the independent risk factor of hemorrhage.Conclusion The postoperative complications of pancreaticoduodenectomy was closely related to alanine aminotransferase level,parenchyma texture and pancreatic duct diameter.

Objective To investigate the difference of efficacy of interlocking nails and dynamic compression plate in tibial shaft fractures.Methods The clinical data of 137 cases with tibial shaft fractures were reviewed retrospectively.They were divided into two groups according to the various treatments which included interlocking nails group(72 cases with 79 fractures) and dynamic compression plate group(65 cases with 70 fractures).The efficacy,healing fineness rate,function score after operation and complications were compared.Results After operation,the patients were followed up 21.4 months on average.The postoperative callus time,weight-bearing limb time,healing time and postoperative fixation time taken in interlocking nails group was shorter than that in dynamic compression plate group [(2.36 ± 0.46) months vs.(3.12 ± 0.57) months,(2.42 ± 0.51) months vs.(3.14 ± 0.63) months,(7.65 ± 1.29) months vs.(9.33 ±1.54) months,(12.64 ± 3.76) months vs.(16.38 ± 3.15) months],and there was significant difference (P＜ 0.05).The healing fineness rate was 97.5％(77/79) in interlocking nails group,and 92.9％(65/70) in dynamic compression plate group,and there was nosignificant difference (x2 =1.76,P ＞0.05).The incidence of comphcations in interlocking nails group was higher than that in dynamic compression plate group[25％(2H9) vs.12.9％(9H0)],and there was significant difference(P ＜ 0.05).Condmions Interlocking nails have better biomechanical features with high union rate,low infective rate and good recovery of joint function.The clinical result of interlocking nails for the tibial shaft fractures is also better than that of dynamic compression plate.

Objective To mine the relation between leukemia and genes using Weka. Methods The papers on leuke-mia and genes were retrieved from PubMed, their subject headings and subheadings were extracted using BICOMB to generate co-occurrence matrix and term-paper matrix. The research hotspots were found by cluster analysis of the data on co-occurrence matrix using Weka and Cobweb. The literature was verified. Results The 42 high fre-quency words were clustered into 7 classes by Weka. No high frequency words of leukemia or genes were found in classes 1, 2, 4 and 5, indicating that their clustering efficiency was poor. The clustering efficiency of the other 3 classes was good. Conclusion Cluster analysis showed that leukemia is related with myc gene, ab1 gene, p53 gene, virus gene, immunoglobulin gene and mdm gene.

Embodied as an abstract concept as well as concrete regulations and material environment on the campus,the campus culture is the organizational culture among universities,which plays a significant role in enhancing students' quality of career starting.Similar to its social culture,the American campus culture is characterized by a strong personal heroism thus is known as a "cowboy culture".As the so-called "dragon culture",the Chinese culture is a more conservative one and thus lack of innovation-oriented career starting concepts among Chinese university students.Therefore,in order to effectively carry out entrepreneurship education in colleges and universities,the innovation-oriented campus culture should be constructed,students' entrepreneurship conception strengthened,thus students' sense of career starting and mental status be enhanced.
