Objective:To study the relationship of retaining time of tympanic ventilation tube and aural complications. Method:Three-hundred-five patients(659 ears)with otitis media with effusion(OME)received tympanostomy tube insertion. The tube were removed 6-36 months after tube insertion. Then aural complications were recorded in different tube retaining time, followed with a statistic analysis. Result: Fifty-five tubes of 29 patients were removed at 1-6 months after tube insertion, with spontaneous extrusion 3.4%, blocked tube 10. 3%, intrusion into the middle ear O, granulation 'tissue O, cholesteatoma O, otorrhea 6.9%, perforation O. One hundred and ninty tubes of 96 patients were removed at 6-12 months after tube insertion,with spontaneous extrusion 7. 3%,blocked tube 15.6%, intrusion into the middle ear 1%, granulation tissue O, cholesteatoma O, otorrhea 5.2%,perforation O. Three huandred and eight tubes of 156 patients were removed at 12-24 months after tube insertion, with spontaneous extrusion 9%,blocked tube 12.8% ,intrusion into the middle ear 1.3%,granulation tissue 1.9% ,cholesteatoma 0.6%,otorrhea 2.5%,perforation was O. One hundred and sixty one tubes of 83 patients were removed at 24-36 months after tube insertion, with spontaneous extrusion 36.1%, blocked tube 53%, intrusion into the middle ear 6%, granulation tissue 3. 6%, cholesteatoma 2.4%, otorrhea 2.4%, perforation 2.4%. Conclusion:The occurrence of complication didn't increase with time going by when the ventilation tube retained less than two years. However, when the ventilation tube retained more than two years, the occurrence of spontaneous extrusion and blocked tube increased obviously.

Objective This research aimed to compare two regimens of anesthesia(vecuronium-fentanyl and cisatracurium-remifentanil)for kidney transplantation patients.Methods 108 patients were studied,45 patients(Group Ⅰ)received balanced anesthesia with vecuronium and fentanyl,to the others 63(Group Ⅱ),cisatracurium and remifentanyl was given.Comparison of the difference between the two groups was made on the extubation time,intraoperative hemodynamics,postoperative urine output,serum creatinine and anesthesia complications.Results Extubation time of the Group Ⅰ was significantly longer than that of Group Ⅱ(33.5min ±17.5min,P＜0.05),but there was no difference between two groups on intraoperative hemodynamics,postoperative urine output,serum creatinine and anesthesia complications.Conclusions Both of the two regimens can provide safe anesthesia for kidney transplantation.Patients received regimen of cisatracurium and remifentanil experienced shorter extubation time.This regimen may be a better anaesthesic regimen for renal transplantation.

The DNA demethylase genes are widespread in plants. Four DNA demethylase genes (LJDME1, LJDME2, LJDME3 and LJDME4) were obtained from transcriptome dataset of Lonicera japonica Thunb by using bioinformatics methods and the proteins' physicochemical properties they encoded were predicted. The phylogenetic tree showed that the four DNA demethylase genes and Arabidopsis thaliana DME had a close relationship. The result of gene expression model showed that four DNA demethylase genes were different between species. The expression levels of LJDME1 and LJDME2 were even more higher in Lonicera japonica var. chinensis than those in L. japonica. LJDME] and LJDME2 maybe regulate the active compounds of L. japonica. This study aims to lay a foundation for further understanding of the function of DNA demethylase genes in L. japonica.

Objective:To investigate the effect of standardized nutritional therapy for gastric cancer during perioperation.Methods:Seventy-six patients with gastric cancer who underwent nutritional therapy were randomly divided into observation group (38 patients) and control group (38 patients),between May 2015 and May 2016.In the observation group,the nutritional therapy was made by medical workers who had received the training of Total Nutritional Therapy (TNT) and Goal Nutrition Therapy (GNT) for Cancer Patient.In the control group,the nutritional therapy was given by doctors according to their conventional experience.Nutritional conditions,gastrointestinal function recovery conditions,complications and hospital stays were compared between the two groups.Results:First,the weight,triceps skinfold thickness and arm muscle circumference of preoperative 1 day and postoperative 7 day in the observation patients were significantly higher than those in the control patients (P ＜ 0.05).Second,the level of serum prealbumin of preoperative 1 day,postoperative 1 and 7 day in the observation patients was significantly higher than that in the control patients (P ＜ 0.05).Third,the time of anus exhaust and defecate in observation group was significantly shorter than that in the control group (P ＜ 0.01).Fourth,each group had one patient who suffered bleeding after operation,and 2 patients in control group had anastomotic leakage.Fifth,the time of hospital stays in the observation group was significantly shorter than that in the control group (P ＜ 0.01).Conclusion:The standardized nutritional therapy for gastric cancer can improve the patient's nutrition status,promote the recovery of gastrointestinal function,and then decrease the time of hospital stays during perioperation.

Objective The aim of the study is to approach the clinical significance of the change of ST segments after di- rect percutaneous transcoronary angioplasty(PTCA) combined with Lipo-PGE_1 in treating Acute Myocardial Infarction (AMI).Methods The change of the ST segments on EKG of 76 patients with AMI are observed in 30 minutes after un- derwent direct PICA combined with Lipo-PGE_1,and the relations are analyzed that are prospectively to their therapy effect,the degree of injured cardiac muscle,the cardial functions,and the prognosis.Results The patients who treated with the PCTA combined with Lipo-PGE_1 ST segments on EKG 30 minutes after operations reduced significantly,cardiac muscle is injured lowly,their cardial functions are better.Conclusion The change of ST segments after direct percutane- ous transcoronary angioplasty (PTCA) combined with Lipo-PGE_1 in treating acute myocardial infarction is one of the guide line to estimate the perfnsion of cardiac muscle,and to estimate prognosis farther.

Objective To explore a method to improve the nutritional state and immune function of patients after radical gastrectomy,and to decrease postoperative complication rate and accelerate recovery from operation.Methods In line with the concept of fast tract surgery (FTS),a new perioperative nutritional schedule was made for patients prior to radical gastrectomy,ehich included preoperative nutritional risk screen and prophylactic enteral nutrition,early postoperative light enteral nutrition,early ambulation and perioperative nursing care.Patients with gastric cancer were randomly assigned into fast track group or a simple control group.New perioperative schedule was executed in the patients of fast track group and traditional nutrition support in control group.After operation,serum albumen was measured to evaluate the patient's nutritional state and serum IgA to evaluate gastrointestinal immune function.In addition,the time to passage of flatus,postoperative recovery time and complication rate after operation were compared.Results Patiens in FTS group (n=35) showed higher serum albumin and serum IgA on d1 and d3 after operation than those in the control group (n=25) (P

Objective To investigate the effects of caveolin-1 overexpressing on the growth of cervical squamous cell cancer Hela cell line. Methods Eukaryotic expression vector of human caveolin-1 gene was introduced into Hela cells by Lipofectamine. The clones stably overexpressed caveolin-1 were identiffed by RT-PCR, immunofluorescence cell staining techniques and Westernblotting. Cells proliferation viabihty was tested by MTT assay, and flow cytometry was used to assay the cell cycle and apoptosis, and the relative phosphorylation level of extracellular regulated protein kinases (Erk1/2) were detected by Westernblotting. Results The clones stably overexpressed caveolin-1 were obtained. Compared with the parental Hela cells, the tranfected cells exhibited a slower rate of growth. FAGS analysis results revealed that overexpression of caveolin-1 resulted in the cell cycle arrest in the G0/G1 [ ( 68. 04 ± 2. 57 ) % vs ( 53.41 ±1.01)%] phase and increased the apoptotic cell fraction[ (19. 18 ±2.20)% vs (5.63 ±0.55)%, P <0. 05 ]. Western blotting results showed that overexpression of caveolin-1 reduced the phosphorylation of Erk1/2(0.28 ±0.05 vs 0.81 ±0.07, P <0.05). Conclusions Overexpression of caveolin-1 suppressed the growth of Hela cells and induced apoptosis, down-regulation of Erk1/2 phosphorylation might be involved in its mechanism.

Sixty-three morphological traits from 743 specimens of the 41 taxa within the cultivated Lonicera japonica were observed and measured, such as the height of plants, the length of leaf, the width of leaf, the length of anther, the alabastrum's number of one branch, the color of alabastrum and so on. A numerical taxonomy is presented by using the cluster analysis, principal components analysis (PCA) and factor analysis. Sixteen of 63 characters were screened by means of PCA and used for cluster analysis of 41 taxa with the method of Ward linkage and average euclidean distance. The cluster analysis showed that the 41 taxa could be divided into 5 groups when the Euclidean distance coefficient was 11.84. The factor analysis indicated that the shape of leaf, color of alabastrum, the pilosity and color of twiggery were of significance for the cultivated L. japonica classification. The results of this study will be a base for the core collection and breeding of L. japonica.
