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.

?AlM: To analyze the result of ultrasound biomicroscopy ( UBM ) of patients with rhegmatogenous retinal detachment ( RRD ) who need to perform pars plana vitrectomy ( PPV ) to explore the value of clinical application of UBM at preoperation.
?METHODS:Patients who underwent PPV for RRD in our hospital from January to December 2014 were selected. The preoperative results of UBM were recorded and the positive findings of UBM were analyzed, the value of preoperative application of UBM was investigated.
?RESULTS:Totally 356 cases (357 eyes) of patients with RRD were received PPV. All patients were examined by UBM, 122 eyes ( 34. 17%) were positive, 56 eyes were ciliochoroidal detachment, 28 eyes were narrow anterior chamber angle, 6 eyes were chamber angle-closure, 28 eyes were ciliary body cyst, 4 eyes were iris cyst, 11 eyes were anterior proliferative vitreoretinopathy, 1 eye was retinal cyst. There were 12 eyes existing two lesions at the same times. ln this study, patients with choroidal detachment was detected by UBM in 56 eyes, the positive rate was 15. 7%, while 25 eyes was detected by B -ultrasonography, the positive was 7. 0%. The difference was statistical significant(χ2=13. 382, P<0. 05).
?CONCLUSlON: The patients with RRD have underwent PPV for the condition of illness, preoperative UBM can be examined to detect the condition of anterior chamber angle, iris, ciliary and anterior choroid, which is significant for comprehensively understanding the preoperative condition of patients, estimating the difficulty of the operation, and guiding operation and the postoperative follow-up.

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 To study the sonographic features of papillary thyroid carcinoma (PTC) associated with cervical lymph nodes metastasis for early diagnosis and prediction of the invaded cervical lymph nodes. Methods The sonographic features of 170 patients with pathologically confirmed PTC in First Afifliated Hospital of Harbin Medical University between 2011 and 2013 were retrospectively reviewed. There were 59 cases with neck lymph nodes metastases and 111 cases without neck lymph nodes metastases. Receiver operating characteristic (ROC) curve was aaplied to analyze the cut-off values of resistance index (RI) and peak systolic velocity (PSV) for judging the presence or absence of cercical lymph node metastasis. The Chi-square test and rank sum test were used to compare the different sonographic features between each group. The Logistic regression analysis was used to obtain the relevant factors of PTCs with cervical lymph node metastasis. Results ROC curve analysis showed that the cut-off values of RI and PSV were 0.735,13.95 cm/s. The primary tumor diameter, the existence of halo, the involvement of thyroid upper pole, the microcalciifcation, the blood suply classiifcation and the RI, PSV were statistically signiifcantly different between PTCs with and without cervical lymph node metastasis, whereas no statistical signiifcance was detected between the primary tumor echo pattern, boundary and the longitudinal/transveral ratio between the metastatic and nonmetastatic group. Logistic regression analysis showed that the PTC primary tumor diameter and PSV were independent factors coorelated with cervical lymph node metastasis. Conclusion Some sonographic features of PTC are closely correlated with lymph nodes metastasis, which are valuable in predicting the cervical lymph nodes metastasis in patients with PTC pre-operatively.

Objective To evaluate the effect of fingolimod(FTY720) on angiotensin Ⅱ(AngⅡ)-induced renal oxidative stress in rats and its possible mechanisms.Methods Thirty-six male Sprague-Dawley rats were divided into three groups through random number tables:AngⅡ infusion group(twelve rats,infusion of AngⅡvia subcutaneous osmotic pumps),0.9% sodium hydrochloride solution infusion group(twelve rats,infusion of equal volume of 0.9% sodium hydrochloride solution via subcutaneous osmotic pumps) and FTY720 intervention group(twelve rats,intra-gastric administration of FTY720 besides AngⅡ infusion).Urine samples were collected for 24 hours every week.Blood samples and kidneys were collected when rats were sacrificed at day 14 and 28 d respectively.MDA and T-SOD assay Kits were used to detect the concentrations of MDA and T-SOD in serum and kidney homogenates.Renal pathological changes were observed by light microscope.The expression of Nox4 in the kidneys was evaluated by immunohistochemistry.Results Compared with 0.9% sodium hydrochloride solution infusion rats of the same period,AngⅡ-infused rats developed significant proteinuria.The concentration of serum creatinine,urea nitrogen,AngⅡ and MDA were increased(P<0.05),T-SOD was significantly decreased on days 14 and 28(P<0.05),the serum albumin was significantly increased on day 28(P<0.05),while FTY720 partially reversed these changes.The renal tissue of AngⅡ-infused rats presented mesangial cells proliferation,mesangial matrix deposition,tubular epithelial cells effacement,sclerosis and atrophy in part of the glomerular.FTY720 can alleviate these changes.Immunohistochemistry showed that Nox4 was primarily located in the distal tubule.The expression of Nox4 was significantly increased in AngⅡ-infused rats as compared with that of 0.9% sodium hydrochloride solution infused group rats,and FTY720 administration prevented the change effectively.Conclusion AngⅡ-induced renal injury could be attenuated by FTY720 via preventing oxidative stress.

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 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 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.
