Guillain-Barré syndrome(GBS) has clinical characteristics:flaccid,symmetrical,ascending paralysis.Cranial nerves and respiratory muscle related,albuminocytologic dissociation in cerebrospinal fluid,and electrophysiological changes.GBS was believed to be an autoimmune perineuropathy.Recently,there were more and more reports about GBS spectrum disorders or GBS variant correlated with anti-GQ1b antibody or anti-GM1 IgG antibody et al.The GBS Classification Group presented the new clinical criteria in 2014,to enable neurologists and non-neurologists to diagnose GBS and all its variants using a simple yet all-inclusive classification system.

Objective To investigate how internet using (both time and activities)and effortful control would contribute to the sex difference of problematic internet use (PIU).Methods A total of 844 adolescents aged 9-20 years old were selected from Chinese Academy of Sciences twin-sample by simple random sampling,with boys accounting for 45.6％ and girls accounting for 54.4％.The internet using and effortful control were measured using self-report questionnaires in the first time(T1),the problematic internet use were measured after one and half years (T2).The difference and relation of Internet using,effortful control and problematic internet use between boys and girls were measured with Chi-square test,t test and correlation analysis.The moderating effect of sex between internet using and PIU were explored by utilizing regression analysis.The mediation effect of effortful control between sex and PIU were explored with Sobel test.Results The anverage internet time of working day and weekend in boys were 1.52 h and 2.12 h respectively.The average internet time of working day and weekend in girls were 1.49 b and 2.05 h respectively.Significant difference between boys and girls is not existed in the internet time (t=0.541,0.907,P＞0.05).And the boy was inclined to game(x2 =47.669,P＜0.01).The effortful control of boys and girls were 54.09 and 55.76 respectively.The score of boys' and girls' PIU were 22.48 and 20.72 respectively.Boys' effortful control was significantly lower than that of girls (t=-2.879,P＜0.01).The score of boys' PIU was significantly higher than that of girls' (t=3.612,P＜0.01).Adolescents' PIU were significantly correlated with the time,entertainment and social activities (r=0.249,0.175,0.140,P＜0.01).The moderating effect of sex was significant in the relation between internet time and PIU.Significant mediation effect of effortful control existed in the PIU difference between boys and girls(Z=-2.54,P＜0.05).Conclusion Significant mediation effect of effortful control exists in gender and PIU.

Objective To establish an animal model of high-iodine and low-protein in Wistar rats,and to observe the effect of combined excess-iodine and low-protein diet on growth,metabolism and morphological changes in thyroid.Methods According to body weight[(110 ± 10)g] and sex(half male and half female),one hundred and ninety-two Wistar rats,1 month after weaning,were randomly divided into ① normal iodine control group (NI),② 10-fold excess-iodine group (10HI),③ 50-fold excess-iodine group (50HI),④ 100-fold excess-iodine group (100HI),⑤ low-protein control group (LC),⑥ low-protein and l 0-fold excess-iodine group (L10HI),⑦low-protein and 50-fold excess-iodine group (L50HI),⑧ low-protein and 100-fold excess-iodine group(L100HI).Twenty-four rats were in each group,with the experimental period of 6 months.The iodine content of NI and LC groups was 4.65 μg/d; 10HI,50HI and 100HI groups were 46.50,232.50 and 465.00 μg/d,respectively.The animal's body weight,water and feed consumption were recorded weekly.At the end of 60,120,180 days,urine and blood samples were collected from eight rats in each group.Urinary iodine was tested by arseni cerium catalytic spectrophotometry; serum iodine was tested by the method of chloric acid.Histological change of the thyroid gland was observed by transmission electron microscopy and hematoxylin-eosin (HE) staining at the end of 6 months; apoptosis of thyroid was tested by terminal-deoxynucleoitidyl transferase mediated nick end labeling (TUNEL) method.Results At the end of 4,8,16,18,22 and 24 weeks,the differences of body mass of rats among groups were statistically significant(F =4.26,3.75,4.98,4.09,3.28,3.95,all P ＜ 0.05).At the end of 60,120,180 days,the differences of iodine concentration in urine and blood among groups were statistically significantly (H =5.37,6.03,all P ＜ 0.05).Light microscopy showed that thyroid follicular epithelial cells became flattened,and follicles became distended with colloid following increasing of iodine concentration.Electron microscopy showed increased glial vesicles,condensation of nuclear chromatin,karyopyknosis,and karyolysis with increasing of iodine concentration.The differences of apoptotic indexes among groups were statistically significant (F =4.59,P ＜ 0.01).The apoptotic indexes of L50HI and L100HI groups [(21.50 ± 5.20)‰,(26.70 ± 6.40)‰] were higher than those of 50HI and 100HI groups [(11.20 ± 4.30)‰,(19.40 ± 4.80)‰,P ＜ 0.01 or ＜ 0.05].Conclusion Excessiodine and low-protein can cause growth retardation,abnormal iodine metabolism,and thyroid follicular epithelium damage in Wistar rats.

OBJECTIVE:To establish the pharmacokinetic-pharmacodynamic(PK-PD) model of Nisoldipine controlled-release patches(NCRP)in spontaneously hypertensive rats(SHR). METHODS:SHR were randomized into a patch(NCRP)group and a tablet(Nisoldipine tablets)group,with 6 rats in each group. The microdialysis probes were implanted in SHR. Each rat was given 5 mg nisoldipine. Plasma microdialysate was collected within 36 h after administration. HPLC was adopted to determine the plasma concentration of nisoldipine,and WinNonlin 5.3 was employed to calculate Pharmacokinetic parameters. With heart rate and blood pressure as pharmacodynamic indexes,PK-PD model study was conducted. RESULTS:Vs. nisoldipine tablets,NCRP has con-trolled release effect. The relationship between NCRP drug effect and effect-site concentration met the Sigmoid-Emax model. The main parameters of the PK-PD model for heart rate and systolic blood pressure were as follows as Emax of (2.65 ± 0.06) and (10.71 ± 0.87),EC50 of (83.65 ± 35.25) and (1.29 ± 0.26) ng/ml,γ of (0.83 ± 0.91) and (1.2 ± 0.35),Keo of (0.37 ± 0.53) and (0.91±0.24)h-1. CONCLUSIONS:PK-PD model of NCRP in SHR has been established successfully.

Objective To analyze the correlation between the resistance of Acinetobacter baumannii and the utilization of antimicrobial agents in the hospitalized patients of Beijng Chuiyangliu Hospital,and provide the basis for clinical rational use antimicrobial agents.Methods A retrospective analysis was conducted for the drug resistance rate and specimen source of the 2 194 strains of Acinetobacter baumannii from 2010 to 2014 in the hospital and DDDs/DUI of antimicrobial agents was analyzed by Pearson correlation.Results The resistance rate of Acinetobacter baumannii was positively correlated with the DDDs and DUI of imipenem/cilastatin(r=0.991,0.994,all P<0.01), and was positively correlated with the DDDs of cefepime(r=0.934,P=0.020).The resistance rate of Acinetobacter baumannii to amikacin was positively correlated with the DDDs of etimicin(r=0.931,P=0.022).The resistance rate of Acinetobacter baumannii was negatively correlated with the DUI of levofloxacin(r =-0.986,P =0.002). Conclusion The resistance rate of Acinetobacter baumannii was high and there was correlation between the drug resistance and the utilization of some antimicrobial agents.

Objective To explore the correlations of lung resistance protein (LRP) and glutathione S transferase π (GST-π) to chemotherapy resistance and prognosis of epithelial ovarian cancer.Methods The expressions of LRP and GST-π in epithelial ovarian cancer were examined with immunohistochemistry.Correlations of LRP and GST-π to chemotherapy efficacy and survival time after operation were analyzed.Results The short-term efficacy rates of ovarian cancer were lower in patients with positive expressions of LRP and GST-π than those with negative expressions [61.2％,61.7％ vs 94.1％,89.5％,x2 =6.47,4.94,P =0.011,P =0.026].The positive rates of LRP and GST-π were significant higher in patients with chemotherapy resistance than in those sensitive to chemotherapy [91.3％,87.0％ vs 65.1％,62.8％,P ＜ 0.05].Log-rank test showed that patients with positive LRP and GST-π had shorter survival time than those negative,and patients with both positive LRP and GST-π had shorter survival time than those both negative (P ＜ 0.05).Conclusions The expressions of LRP and GST-π in epithelial ovarian cancer could be used to predict chemotherapy resistance and prognosis of patients.

Objective To evaluate the relationship between endoscopic rectal aberrant crypt foci (ACF) and colon neoplasm, including lesions with high risk of aggressive progression (adenoma with diameter ≥ 1cm, villus adenoma, tubular-villus adenoma, adenoma of high grade dysplasia, or cancer). Methods The rectum of 212 patients who underwent colonoscopy was stained by 0. 4% indigo armine, and the patient was classified into different grade according to the number of rectal ACF, namely Grade 0 as no ACF, Grade Ⅰ as 1-4, Grade Ⅱ as 5-9 and Grade Ⅲ as more than 10. The correlation between rectal ACF grade and colon lesions was analyzed. Results Of 212 patients, 72 were classified as Grade 0, 48 as Grade Ⅰ , 41 as Grade Ⅱ, and 51 as Grade Ⅲ. The detection rate of colon neoplasm and lesions with high risk of aggressive progression in patients with rectal ACF were significantly higher than that in patients without rectal ACF (OR at 95% CI was 22. 352 (6. 716 -74. 395) and 7. 982 ( 1. 838-34. 672), respcetively). Conclusion Rectal ACF may predict the detection of colon lesions, including those with high risk of aggressive progression.

Objective To investigate the differences and characteristics of virulence genes carried by Salmonella enteritidis from different sources in Shijiazhuang City.Methods One hundred and twenty-four strains of Salmonella enteritidis isolated from morning markets of raw and poultry stalls,slaughterhouses and food poisoning specimens in Shijiazhuang area were collected.Eight virulence genes (invA,sopE,agfA,spvR,hilA,stn,pefA,shdA) were detected by polymerase chain reaction (PCR).Results Salmonella enteritidis might have different virulence gene profiles.The above eight virulence genes were detected in different strains.The carrying rate of virulence genes invA,sopE,stn,hilA,spvR and pefA in the food poisoning strains was higher than 94％.There was no difference in the carrying rate of 8 virulence gene between the morning raw poultry stalls isolates and the patient strains,but was different with the slaughterhouse strains.Conclusion There were more risks of food poisoning caused by Salmonella enteritidis from morning markets,and the hygiene supervision should be strengthened to prevent and control foodborne disease.
