Objective To explore the main influencing factors of recurrent stroke.Methods 2 065 new stroke patients were selected as study populations.The recurrent stroke status and kinds of influencing factors were followed up.The follow-up study time was 3 years.Single factor and multi-factor analysis methods were carried out for influencing factom of recurrent stroke by Cox proportional hazaIds regression models.Results By the end.1 881 pa%);45 patients were recurrent in 6accepted visit,184 were lost follow-up.327 patients were recurrent(17.38tients months(13.76%);68 patients were recurrent during 6 months to 1 year(20.80%);97 patients were recurrent during 1 year to 2 years(29.66%);117 patients were recurrent after 3 years(35.78%).Single factor Cox regression analysis:The risk factors of recurrent stroke were advanced age(RR=1.48),smoking(RR=1.35),fat intake(RR=1.83),hypertension history(RR=2.54),diabetes history(RR=1.72),high lipemia(RR=1.83),stroke family history(RR=2.62),depression(RR=1.84),life events(RR=2.53),fibrinogen(RR=1.75),carotid plaques(RR=2.68);The protecting favors of recurrent stroke were female(RR=0.64),sports(RR=0.33),social support(RR=0.36).Multi-factor Cox regression analysis:the risk factors of recurrent stroke were hypertension history(RR=1.86),high lipemia(RR=1.95),stroke family history(RR=2.62),life events(RR=2.38),carotid plaques(RR=2.77);The protecting factors of recurrent stroke were sports(RR:0.35),social support(RR=0.32).Conclusion The prevention of hypertension history,high lipemia,the family history of stroke,more supports and the high ability of answering life events could help to prevent the recurrent stroke.

Molecularly imprinted polymer (MIP) was synthesized by precipitation polymerization using ribavirin as the template molecule and methacrylic acid as the functional monomer.The sensitive film of ribavirin electrode was constructed by molecularly imprinted polymer doped with graphene oxide as the ionophore, poly(vinylchloride) (PVC) as matrix and dioctyl sebacate for plasticizer.The results showed that the best performance of the electrode was obtained when the sensitive film compositions were 100.8 mg of MIP, 14.7 mg of GO, 450.8 mg of PVC and 901.6 mg of dioctyl sebacate, and the inner filling solution composition was 0.1 mol/L NaCl + 0.05 mol/L NaAc-0.05 mol/L HAc + 1.0×10.-5 mol/L ribavirin solution.The electrode showed a near-Nernstian slope of 45.565 mV/decade for ribavirin over the range of 1.0×10.6-1.0×10.-4 mol/L and a detection limit of 1.0×10.-7 mol/L.The electrode could be used in the pH range of 3 to 5 with response time of less than 3 min.The developed electrode exhibited high selectivity for ribavirin and was successfully applied to the determination of ribavirin in feed and injection with recoveries of 90%-110% and RSD of 3.0%-7.9%.

Objective To investigate the incidence of adult epilepsy patients with attention-deficit hyperactivity disorder (ADHD) and the characteristics of ADHD subtypes, and to explore the correlations between several epilepsy-related factors and ADHD. Methods According to corresponding inclusion criteria and exclusion criteria, 82 adult epilepsy patients from March 2012 to March 2016 were enrolled as study group. Eighty-two healthy adults were enrolled as the control group. Using the Chi-square test and Logistic regression analysis and the other statistical methods, the phenomenon of ADHD in adults with epilepsy and the factors that may contribute to the phenomenon was analyzed. Results The detection rate of ADHD in 82 adult patients with epilepsy was 26.8%(22/82), significantly higher than that in the heathly control group which was 4.9%(4/82),χ2=18.672, P<0.05. Symptomatic epilepsy 8/17 and the electroencephalogram showed multifocal discharge 6/14 had higher detection rate of comorbid ADHD and the difference was statistically significant (P<0.01). The results of binary Logistic regression analysis showed that epilepsy age of onset was possibly an important factor for epilepsy with ADHD (B=-0.891, P<0.05). Conclusions The risk of ADHD in adults with epilepsy is higher than that in the healthy adults and attention-deficit is the common subtype. The etiology, age of onset and electroencephalogram features of adults with epilepsy may be associated with the occurrence of ADHD.

Double template molecularly imprinted polymer ( D_MIP) was prepared by emulsion polymerization method using the nonylphenol (NP), bisphenol A (BPA) as templates, α_methyl methacrylate(MAA) as functional monomer. Then using the D_MIP as solid phase extraction materials, a method based on double_molecularly imprinted solid phase extraction coupled with high performance liquid chromatographic fluorescence detection was developed for the determination of trace NP and BPA from environmental and food samples. The D_MIP was characterized by Fourier transform infrared spectroscopy ( FT_IR ) and adsorption experiments. The results showed that the saturated adsorption capacity of the D_MIP for NP and BPA was 73. 3 and 97. 5 mg/g, respectively, and the relative selectivity coefficient was 2. 2 and 1. 7, respectively. Moreover, the conditions affecting extraction efficiency, such as washing conditions and desorption conditions were optimized. Under the optimal conditions, there was a good linear correlation in the concentration range of 0. 01-2. 3 mg/L with correlation coefficients (R2) greater than 0. 998 for NP and BPA. The detection limits ( S/N=3) were 0. 001 and 0. 002 mg/L. The proposed method was applied to determine NP and BPA in river water, beer and crucian carp samples. The recoveries of NP and BPA were in the range of 86. 4%-99. 1%with the relative standard deviation less than 6 . 2%. This method has good selectivity and high sensitivity and shows good prospects for the application in the enrichment and separation of NP and BPA in real samples.

Nutritional studies were made on eleven elderly male hospitalized patients (60-83 years old) receiving nasogastric feeding for from several months to as long as 10 years duration.The major nutrients intake obtained was listed in table 1. According to the physical examination, biochemical parameter of the blood and nitrogen balance, the average intake 1722 kcal of enegy (1175-2700 kcal) and 82.4 g of protein (52.6-117.3g) probably met the need of the patients. Vitamin status (B1 B2 C) by blood and urine examination was rather good because of taking additional vitamin preparation regularly daily besides meal sources. Blood cholesterol concentration was moderately higher (339.3mg/dl) than the normal value possibly due to excessive daily intake. It suggested that the intake of cholesterol should be restricted.A better nasogastric feeding regimen was presented and discussed.
