Objective To investigate the effects of different duration of sevoflurane anesthesia in the neonatal period on the long?term cognitive function and hippocampal synaptic plasticity in rats. Methods Twenty?four pathogen?free healthy Sprague?Dawley rats of both sexes, aged 7 days, weighing 12-16 g, were divided into 3 groups ( n=8 each) using a random number table: control group ( group C) , sevoflu?rane anesthesia for 2 h group ( group S1 ) , and sevoflurane anesthesia for 6 h group ( group S2 ) . Group S1 and group S2 inhaled 2% sevoflurane for 2 and 6 h, respectively. Morris water maze test was performed at 30 days after the end of anesthesia ( postnatal day 37) to assess the cognitive function. After the end of the test, the rats were sacrificed, and hippocampi were isolated for determination of the expression of brain?de?rived neurotrophic factor ( BDNF) , postsynaptic density?95 ( PSD?95) and synapsin 1 in hippocampal tis?sues by Western blot. Results Compared with group C, the escape latency on 4th and 5th days of the test in group S1 and on 2nd-5th days of the test in group S2 was significantly prolonged, and the frequency of crossing the original platform was significantly decreased, and the time of staying at the platform quadrant was significantly shortened in S1 and S2 groups, the expression of BDNF, PSD?95 and synapsin 1 in hipp?ocampal tissues was significantly down?regulated in group S2 (P<0?05), and no significant change was found in the expression of BDNF, PSD?95 and synapsin 1 in hippocampal tissues in group S1 ( P>0?05) . Compared with group S1 , no significant change was found in the escape latency and frequency of crossing
the original platform (P>0?05), the time of staying at the platform quadrant was significantly shortened, and the expression of BDNF, PSD?95 and synapsin 1 in hippocampal tissues was significantly down?regula?ted in group S2 ( P<0?05) . Conclusion Short?time and long?time sevoflurane anesthesia both can induce long?term cognitive dysfunction in the neonatal period, and the severity is aggravated with prolonged anes?thesia; the partial mechanism is related to inhibition of the synaptic plasticity of hippocampal neurons of rats.

Objective To summarize the clinical symptoms of patients with non-erosive reflux disease(NERD) and reflux esophagitis(RE),which is helpful to the differential diagnosis.Methods Outpatients who met the criteria of NERD or RE according to the Montreal definition in Gastroenterology Department Wuhan Union Hospital from 2010-2014 were enrolled in our study.Clinical data were comprehensively collected.Incidence of disease,severity,frequency of esophageal and extraesophageal symptoms,and the rates of overlapping with functional dyspepsia (FD) or irritable bowel syndrome (IBS) were all studied.Results Totally 446 subjects were recruited,including 225 patients with NERD and 221patients with RE.The occurrence rates of esophageal symptoms including heartburn [76.0％ (171/225) vs 52.0％ (115/221),P ＜ 0.01] and acid regurgitation [74.7％ (168/225) vs 54.3％ (120/221),P ＜0.05] in NERD group were significantly higher than those in RE patients,with more severe and frequent (P ＜ 0.05).Despite the rates of food regurgitation were similar,NERD patients behaved more severely and frequently (P ＜ 0.05).Extraesophageal symptoms including throat burning and foreign body sensation in NERD group [40.9％ (92/225) vs 27.6％ (61/221),42.2％ (95/225) vs 31.7％ (70/221),all P ＜0.05] were also higher than those in RE group,the degree of which was more severe too (P ＜ 0.05).RE patients claimed a higher proportion of chronic cough.The incidences of overlapping with IBS in two groups were similar.But there were more patients with FD in NERD group [72.0％ (162/225) vs 62.9％ (139/221),P ＜ 0.05] than in RE group.Conclusions The menifestations and degree of esophageal and extraesophageal symptoms in patients with NERD or RE are different,as well as comorbidities such as FD and IBS.These results suggest that NERD and RE are independent diseases.

Objective To investigate the relationships among distal contractile integral (DCI), ineffective esophageal motility (IEM)and gastroesophageal reflux through high resolution manometry (HRM)in patients with gastroesophageal reflux disease (GERD).Methods A total of 69 patients with GERD were enrolled.All patients received HRM and 24 hour pH and impedance monitoring examination. Pearson correlation analysis was performed to analyze the correlation between DCI,number of invalid swallowing and DeMeester score.All the patients were divided into three groups according to the number of invalid swallowing in 10 times of 5 mL liquid swallowing test.Patients with 5 to 10 invalid swallowing was in IEM group (n=21),one to four was in abnormal motility group (n=19),and zero was in normal motility group (n=29).The t test was performed for comparison of average DCI,average DCI of residual effective swallowing,DeMeester score,acid reflux time,bolus exposure time and proximal reflux times
among the three groups.Results Among the 69 patients with GERD,there was negative correlation between DCI and DeMeester score (r=-0.363,P =0.003)in 10 times of 5 mL liquid swallowing test;the number of invalid swallowing was positively correlated with DeMeester score (r=0.374,P =0.002). The mean DCI in 10 times of 5 mL liquid swallowing of normal motility group,abnormal motility group and IEM group was (1 458.96±545 .10),(986.48 ±577.50)and (288.50 ±167.25 )mmHg·s·cm, respectively,and that of IEM group was lower than normal motility group and abnormal motility group (t =-11 .42 and -2.12,both P <0.05).The average DCI of residual effective swallowing of normal motility group,abnormal motility group and IEM group was (1 458.96 ± 545 .10 ),(1 187.90 ± 669.40)and (450.78 ±350.73 )mmHg ·s ·cm,respectively,and that of IEM group was also lower than normal motility group and abnormal motility group (t = -8.05 and -5 .27,both P <0.01 ).The DeMeester score of IEM group (15 .42±8.79)was higher than that of normal motility group (6.34±3.45),and the difference was statistically significant (t=2.43,P <0.05).The acid reflux time and bolus exposure time of IEM group were (54.93 ± 37.07 )min and (0.64 ±0.49 )%,respectively,which were longer than abnormal motility group ((37.37±22.66)min,(0.52 ±0.24)%)and normal motility group ((21 .22 ± 13.98)min,(0.39 ±0.14)%),and the differences were statistically significant (t =2.36,2.17,2.60 and 2.54,all P <0.05).The total number of reflux of IEM group and abnormal motility group were 67.10± 32.94 and 57.26±38.90,which were both more than that of normal motility group (44.61 ±23.84),and the differences were statistically significant (t =2.48 and 2.17,both P <0.05 ).Conclusions DCI and the number of invalid swallowing can predict reflux condition of GERD patients in a certain degree.The contraction strength of esophageal body was the weakest and esophageal clearance was the worst in IEM group.

Objective:To investigate the risk factors of musculoskeletal disorders(MSDs)in dental postgraduates.Methods:271 dental postgraduates majoring in five different specialties(orthodontics,prosthodontics,endodontics,periodontics and alveolar surgery) with average (2.78 ±1 .57)years of clinical practice were recruited.254 age-matched non-dental postgraduates were served as the controls.The standardized Nordic questionnaire on MSDs and a self-report questionnaire regarding correlative factors were answered. Reliability of the responses was assessed by applying test-retest method.Results:The test-retest method revealed a high reliability of participants'answers with the intraclass correlation coefficient ranging from 0.89 to 0.96.Dental postgraduates had significantly higher incidence (85.6%)of MSDs than the controls(70.4%).In all included dental specialties,high prevalence of MSDs was reported at neck (47.5%-69.8%),followed by shoulders (50.8%-65.1 %),lowerback (27.1 %-51 .2%)and upper back (25.6%-46.5%).Meanwhile,the high prevalence of MSD varied in different specialties.Year of clinical work,clinical hours per week and desk hours per week were found to be the risk factors for MSDs,whereas physical exercise and rest were protective factors.Conclu-sion:MSDs with high prevelence and distinct specialty-related characteristics initiate at the early stage of dental career.Relevant measures to prevent and protect against MSDs should be taken during school-days.

Objective To compare the effects of dexmedetomidine (DEX) and remifentainil (REM) combined with sevoflurane (SEV) for general anesthesia on recovery quality in patients undergoing laparoscopic cholecystectomy (LC).Methods Sixty patients (ASA grade Ⅰ-Ⅱ) who underwent LC were divided into DEX combined with SEV for general anesthesia group (DEX group) and REM combined with SEV for general anesthesia group (REM group) by table of random digit,with 30 cases each.Time of first inspiration,eye opening,extubation,orientation recovery and passage of gas by anus were recorded.Vital sign,numeric rating score (NRS),Ramsay score and untoward reaction were recorded.Degree of satisfaction of patients,post-anesthesia care unit (PACU) nurse and surgeon were evaluated.Results The time of extubation and passage of gas by anus in DEX group were significantly shorter than those in REM group [(12.0 ±3.9) min vs.(15.9 ±5.6) min,t =-3.130,P =0.003; (18.5 ±3.4) h vs.(23.6 ±5.8) h,t =-5.455,P =0.000].However,the time of eye opening and orientation recovery in DEX group were significantly longer than those in REM group [(15.5 ± 4.2) min vs.(11.7 ± 2.9) min,t =4.078,P =0.000;(19.5 ± 4.5) min vs.(14.8 ± 3.6) min,t =4.315,P =0.000].During the first 2 h after operation,Ramsay score in DEX group was significantly higher than that in REM group (P ＜ 0.05),but NRS in DEX group was significanty lower than that in REM group (P ＜ 0.05),the patients with additional analgesics was minor than REM group (2 cases vs.9 cases,P ＜ 0.05).The percentages of patients suffering shivering and postoperative nausea and vomiting in DEX group were significantly lower than those in REM group [3.3％(1/30) vs.33.3％(10/30),6.7％(2/30) vs.30.0％ (9/30),P ＜0.05].Degree of satisfaction of patients and PACU nurse in DEX group were higher than those in REM group [89.0(72.0-100.0) scores vs.80.0(70.0-95.0) scores,Z =-4.066,P =0.000; 92.0 (80.0-99.0) scores vs.90.0 (80.0-95.0) scores,Z =-2.906,P =0.004],but degree of satisfaction of surgeon in REM group was higher than that in DEX group [(91.8 ± 5.8) scores vs.(81.7 ±6.1) scores,t =-6.568,P =0.004].Conclusion Compared with REM combined with SEV for general anesthesia,DEX combined with SEV for general anesthesia has a faster recovery for respiration and passing of gas by anus,lower NRS and incidence rates of shivering,nausea and vomiting,improves the quality of recovery for patients undergoing LC.

Objective To study the feasibility of DCE-MRI application in the orthotopic transplantation model of gastric cancer in nude mice.Methods Orthotopic transplantation model of gastric cancer in nude mice was established, and 15 models underwent DCE-MRI using the contrast agent of gadopentetate.Subsequently, the tumor was dissected in order to detect the MVD.The MVD was compared between orthotopic transplantation tumor model of gastric cancer and normal gastric mucosa.Results Fifteen nude mice with orthotopic transplantation of gastric cancer successfully underwent DCE-MRI examination.As for the cancer, the values of Ktrans, Kep and Ve were (2.11±0.44) min-1, (4.59±0.93) min-1, and 0.46±0.06, respectively.The MVD in gastric cancer tissues was significantly higher than that in normal gastric mucosa (χ2=16.205, P<0.001).Conclusion DCE-MRI can be used for noninvasively quantitative evaluation of vascular parameters of gastric carcinoma.

Objective To investigate the role and the mechanism of ppk1 gene (coding for polyphosphate kinase 1) in oxidative stress resistance in uropathogenic Escherichia coli (UPEC).MethodsMutant strains with ppk1-deletion (△pk1) and complemented strains (△pk1-C) were constructed based on the UPEC strain CFT073.A comparative analysis was conducted to analyze survival rates of CFT073, △pk1 and △pk1-C strains at different time points while they were under oxidative stress.Differences in protein expression between CFT073 and △pk1 strains were analyzed using mass spectrometric analysis.Differences between CFT073 and △pk1 strains in expression of katG and katE genes were analyzed using real-time quantitative RT-PCR.Results The survival rate of △pk1 strains was lower than that of CFT073 strains at every time point, while the survival rate of △pk1-C strains was basically the same as that of CFT073 strains.Gel image analysis and mass spectrometric analysis revealed that six proteins were down-regulated and one was up-regulated in △pk1 strains as compared with those in CFT073 strains.Expression of the catalase-coding genes katG and katE in △pk1 strains were respectively (20.5±8.2)% and (20.9±6.9)% of those in CFT073 strains (P<0.05).Conclusion The ppk1 gene plays an important role in oxidative stress resistance in UPEC by modulating the expression of catalase-coding genes katG and katE.
