Objective:To prepare and preliminarily identify the monoclonal antibodies(mAbs) specifically against 3D protein of Enterovirus 71(EV71),using bioinformatics to predict the epitopes of 3D,with HBc protein as a carrier.Methods: Artificial screening of 3D protein epitope sequences by bioinformatic method,inserted into the major immunodominant region(MIR) area of Hepatitis B virus core protein(HBc),to construct the recombinant protein.BALB/c mice were immunized with the recombinant virus like particles(VLPs),to prepare the mAbs against 3D protein of EV71.Affinity chromatography technology was used to purify the mAb.The indirect ELISA,ELISPOT,immunofluorescence and immunohistochemistry staining methods were used to identify the characteristic of the mAb.Results: We displayed 3D(aa34-43),3D(aa61-76) and 3D(aa151-164) epitopes by constructing fusion protein using HBc VLPs as a vector,after hybridization,one positive hybridoma cell line(3E1) was selected by ELISA.The isotype of 3E1 was IgG2a.The results of immunofluorescence and immunohistochemistry staining assay showed that the mAb 3E1 could specifically recognize EV71.Conclusion: The prepared mAb 3E1 can specifically recognizes the EV71,which laid the foundation for the detection of virus and further study on 3D protein,and verified the bioinformatics technology combined with HBc carrier displaying peptides could prepare mAb quickly and efficiently.

OBJECTIVETo study the association of human epidermal growth factor receptor family molecules expression in gastric cancer tissues with the prognosis of patients with gastric cancer.

METHODSClinical data of 161 patients with gastric cancer undergoing gastrectomy in Jiangsu Cancer Hospital between January 2006 and January 2007 were analyzed retrospectively. The expression of HER1, HER2, HER3 and HER4 was detected by immunohistochemistry. Association of the expression of HER family with the prognosis of patients was examined. Kaplan-Meier method was used to analyze the survival.

RESULTSHigh expression rates of HER1, HER2, HER3 and HER4 were 46.0% (74/161), 10.6% (17/161),55.9% (90/161) and 68.3% (110/161) respectively. Univariate analysis revealed that high expression of HER3 was associated with tumor invasion depth, lymph node metastasis, stage, neurovascular invasion, and overall 4-year survival. High expression of HER4 was associated with tumor distant metastasis and stage. High co-expression of HER2 and HER3 was associated with overall 4-year survival (P=0.023). Multivariate analysis revealed that high expression of HER3 and stage were prognostic independent factors.

CONCLUSIONUp-regulated expression of HER3 is associated with the poor prognosis in gastric cancer patients.

Objective To investigate the level of the serum IL-23 and its correlation with serum biochemical indices of liver function tests and HBV DNA load in patients with chronic severe hepatitis B.Methods Fifty patients with chronic severe hepatitis B (severe hepatitis group) and 18 healthy controls (control group ) were enrolled in the study.The serum IL-23 expression level was detected by ELISA method.The correlation between IL-23 and ALT,AST,TBil,HBV DNA load was analyzed using Pearson's correlation analysis,respectively. Results Serum IL-23 expression level in severe hepatitis group was significantly higher than that of control group ( P ＜ 0.05).Serum IL-23 level was positively correlated with serum ALT,AST,respectively (P ＜ 0.05),but was not correlated with TBil and HBV DNA load,respectively ( P ＞ 0.05 ).Conclusion Serum IL-23 expression level was increased in patients with chronic severe hepatitis B and was associated with the severe of inflammation.We,therefore,believe that IL-23 might be involved in the pathogenesis of chronic severe hepatitis B.

Objective:To investigate the effect of dexmedetomidine combined with parecoxib sodium on multimode analgesia during total knee arthroplasty (TKA) and its effect on cognitive function.Methods:One hundred and eighty-eight patients who underwent TKA from January 2017 to December 2019 in People′s Hospital of Xuyi County were divided into the multimode analgesia (MA) group and the postoperative patient-controlled intravenous analgesia (PCIA) group by the method of random number table, each group with 94 patients. Patients in the MA group were injected with parecoxib sodium and dexmedetomidine hydrochloride half an hour before anesthesia induction and PCIA after the operation, while PCIA was only given after the operation in the PCIA group. Visual analogue scale (VAS) and sedation Ramsay scores were performed at the time of entry into the operation room (T 0), 12 h (T 1), 24 h (T 2) and 48 h (T 3) postoperatively; simple mental state scale (MMSE) score, serum S-100β, and neuron-specific enolase (NSE) levels were measured at 24 h before the operation (T 01), T 2, and 72 h after the operation (T 4). The incidence of adverse reactions within 48 h after surgery and postoperatively cognitive dysfunction (POCD) in the two groups within 72 h after surgery were recorded and compared. Results:The VAS scores and sufentanil dosage at T 1, T 2 and T 3 in the MA group were significantly lower than those in the PCIA group ( P<0.05), and Ramsay scores were significantly higher than those in the PCIA group ( P<0.05). The total incidence of adverse reactions and POCD in the MA group were significantly lower than that in the PCIA group: 5.32% (5/94) vs. 20.21%(19/94), 8.51%(8/94) vs. 27.66%(26/94), there were significant differences ( P<0.05). At T 2 and T 4, the MMSE scores in the MA group were significantly higher than that in the PCIA group: (26.42 ± 1.68) scores vs. (25.30 ± 1.74) scores, (27.06 ± 1.93) scores vs. (26.49 ± 1.87) scores; the S-100β level in the MA group were significantly lower than that in the PCIA group: (1.35 ± 0.17) μg/L vs. (1.43 ± 0.19) μg/L, (1.26 ± 0.13) μg/L vs. (1.40 ± 0.16) μg/L; the NSE level in the MA group were significantly lower than that in the PCIA group: (0.88 ± 0.05) μg/L vs. (0.94 ± 0.06) μg/L, (0.83 ± 0.06) μg/L vs. (0.91 ± 0.04) μg/L, there were significant differences ( P<0.05). Conclusions:Dexmedetomidine combined with parecoxib sodium multimode analgesia has clear analgesia effect after TKA, can significantly reduce the occurrence of POCD and has high safety.

Objective To evaluate the effects of GLYX-13 on cognitive function after long-time isoflurane anesthesia in mice. Methods A total of 192 healthy male C57∕B6J mice, aged 8 weeks, weig-hing 22-25 g, were divided into 4 groups(n=48 each)using a random number table: control group (group C), isoflurane anesthesia group(group I), GLYX-13 group(group G), and isoflurane anesthesia plus GLYX-13 group(group IG). The animals were exposed to 15% isoflurane for 6 h in I and IG groups. GLYX-13 1 mg∕kg was injected via the caudal vein at 2 h before anesthesia in G and IG groups. Novel ob-ject recognition test and contextual fear conditioning test were performed on 1st, 3rd and 7th days after an-esthesia. The expression of 2B subunits-containing NMDA receptor(NR2B)and cyclic adenosine mono-phosphate response element-binding protein(CREB)mRNA in the hippocampus was detected by quantita-tive real-time polymerase chain reaction after the end of behavioral tests on 1st, 3rd and 7th days after anes-thesia. Results Compared with group C, the percentage of time spent in exploring a novel object, dis-crimination index and percentage of freezing time were significantly decreased, and the expression of NR2B and CREB mRNA in the hippocampus was down-regulated in group I(P <005). Compared with group I, the percentage of time spent in exploring a novel object, discrimination index and percentage of freezing time were significantly increased, and the expression of NR2B and CREB mRNA in the hippocampus was up-regulated in group IG(P <005). Conclusion GLYX-13 can significantly improve the cognitive func-tion after long-time isoflurane anesthesia in mice.

Objective To observe the effect of speech therapy in group on children with autism spectrum disorders(ASD). Methods From July,2014 to July,2015,60 children with ASD were randomly divided into control group(n=30)and ex-perimental group(n=30).Both groups accepted regular rehabilitation training,while the experimental group ac-cepted speech therapy in group in addition,for six months.They were assessed with Autism Behavior Checklist (ABC)and Autism Treatment Evaluation Checklist(ATEC)before and after training,. Results The scores of ABC in both groups decreased after training(t>3.079,P<0.01),and decreased more in the experi-mental group(t=3.149,P<0.01).The score of Health/Physical/Behavior and total score of ATEC decreased in the control group(t>3.018,P<0.01),while the scores of all the items of ATEC decreased in the experimental group (t>2.498,P<0.05)after treatment.The scores of all the items of ATEC decreased more in the experimental group than in the control group(t>2.027,P<0.05). Conclusion The addition of speech therapy in group can further improve the behavior in children with ASD.

Objective To evaluate the relationship between the levels of HBV DNA loads and beth the clinical characteristics and 48-week prognosis in patients with decompensated cirrhosis due to hepatitis B. Methods One hundred and forty-three patients with deeompensated cirrhosis of hepatitis B virus infection were divided into lowlevel HBV DNA group [HBV DNA < 105 copies/ml = (46 cases) and high-level HBV-DNA group(HBV DNA 105 copies/ml)(97 cases)]. 21 cases in low-level group and 52 cases in high-level group treated with nucleoside analog. Results There was no significant difference between the two groups on the demography and the baseline in ALT, ALB, TBil, CHE before treatment, while in AST and HBeAg were statistically different. At 48-week, there was no significant difference between the two groups on the liver function. The mortality rate in low-level group was similar to that in high level group. In the low-level HBV DNA patients, hepatocellular carcinoma, spontaneous peritonitis and gnstrointestiual hemorrhage were higer than that in the high-level HBV DNA patients. Conclusion In patients with decompensated cirrhosis due to hepatitis B, those who were in low-level HBV DNA had not got better than that in high-level HBV DNA, which indicated that earlier treatment was also needed in low-level HBV DNA patients.

Objective To investigate the levels of HBsAg in predicting the efficacy of peglated interferon-alpha 2a combined with adefovir dipivoxil( ADV ), in HBeAg-positive chronic hepatitis B patients.Methods This trial enrolled 62 HBeAg-positive chronic hepatitis B patients with detectable HBsAg for at least 6 months prior to screening, serum HBV DNA levels of at least 100 000 IU/ml. The efficacy assessment: viral suppression below 100 IU/ml. The patients with HBV DNA ≤ 100 IU/ml after 24 weeks therapy were divided into group A, in which monotherapy continued; While the rest were divided into group B, in which ADV was combined until week 48. In group B, at the end-of-treatment, the patients with HBV DNA ≤100 IU/ml were divided into group B1, the rest were divided into group B2. Results There was no significant difference on the beseline characteristics of patients between B1 and B2. There was significant difference on the levels of HBsAg at 12-week and 24-week between B1 and B2; while there was no significant difference on the levels of HBeAg. Conclusions The levels of HBsAg at 12-week and 24-week would be predictors to evaluate the efficacy of combined therapy in HBeAg-positive chronic hepatitis B patients.
