Objective To compare the timeliness, success and mortality rates between the modified carotid artery puncture method ( MCAPM) and standard suture method ( SSM) in the establishment of rat model of a middle cerebral ar?tery occlusion ( MCAO) . Methods Thirty?two male rats were randomly and equally assigned into MCAPM group and SSM group. The MCAO models were established by inserting a thread into the common carotid artery ( CCA) . 24 h after modeling, the rats of the two groups were evaluated with Bederson neurological scores, and the modeling success rate and mortality rate were analyzed. Results The suture insertion times, success rates and mortality rates of the MCAPM vs. SSM groups were (82?3 ±17?4) s versus (164?6 ± 22?0) s (P<0?01), 87?5% versus 68?75% (P>0?05), and 6?25% versus 18?75% (P>0?05). Conclusions MCAPM can be used to establish the rat model of MCAO due to its simplicity, mild wound and feasibility.

Objective To evaluate the clinical efficacy of small endoscopic sphincterotomy combined large-bal-loon dilation in treatment of common bile duct stones 1.0~2.5 cm in diameter. Methods 426 patients with large common bile duct (CBD) stones 1.0~2.5 cm in size were reviewed in our hospital between June 2010 and June 2014. They were randomized underwent small endoscopic sphincterotomy combined large-balloon dilation (SESPLBD) (n=218) or endoscopic sphincterotomy (EST) ( n= 208) for lithotripsy. The therapeutic outcome and complications were reviewed and compared. Results SESPLBD had higher complete duct clearance in one session (95.41 % vs. 93.75%), but there was no statistical significant difference. Bleeding was much less occurred in SESPLBD than in EST (2.29 % vs. 7.69 %, P= 0.025), especially when the stones were bigger than 1.5 cm in diameter. Mechanical lithotripsy was performed less in SESPLBD (13.76%vs 25.96 %, P=0.002), especially when the stones were 1.5 ~2.0 cm in diameter. There was no statistical significant difference in the incidence rate of post-ERCP pancreatitis (9.17 % vs. 6.73 %,P = 0.452), hyperamylasemia (19.72 % vs. 18.27 %,P = 0.796), perforation and death. Conclusions SESPLBD could be a safe method for large bile duct stones 1.0~2.5 cm in size. Compared with routine EST, it had less bleeding rate and mechanical lithotripsy requirement without increasing the incidence rate of post-ERCP pancreatitis or hyperamylasemia.

Objective To investigate the antimicrobial resistance mechanisms and genetic homogeny of Salmonella from community acquired infections in Shenzhen,China.Methods Ninety-three of Salmonella were isolated from 2002 to 2007 at Shenzhen People's Hospital,China.PCR and DNA sequencing were used to investigate the mutation in QRDR of the gyrA,gyrB,parC and parE.Plasmid mediated quinolone resistance genes including qnr and aac(6')-Ib-cr,β-lactamase genes including blaTEM,blaSHV,blaOXA, blaCTX-M, and class 1 integron were detected. All isolates were typed by PFGE. Results S. enterica typhi and S. enterica paratyphi A were susceptible to ampicillin, chloramphenicol, trimethoprim/sulfamethoxazole, ceftriaxone and ciprofloxacin, with the susceptible rate of 96%-100%. Fifty-two percent (13/25) of S. enterica typhi and 95% (61/64) of S. enterica paratyphi A were resistant to nalidixic acid. Twenty-four percent (6/25) of nalidixic acid-resistant S. enterica typhi and 94% (60/64) of nalidixic acid-resistant S. enterica paratyphi A showed decreased susceptibility to ciprofloxacin (MIC of 0. 125-1 μg/ml).All nalidixic acid-resistant (susceptible to ciprofloxacin ) Salmonella (NARS) isolates had a single substitution in the QRDR of GyrA, and 91% (68/75) of these isolates carried the substitution Ser83Phe in GyrA. Two mutations in the QRDR of GyrA were detected in both of two ciprnfloxacin-resistant Salmonella,with the additional one mutation in the QRDR of parC. Plasmid mediated quinolone resistance genes including qnr and aac(6')-lb-cr were not detected in any isolate. The blaCTX-M-14 gene was detected in a ceftriaxoneresistant isolate of S. enterica paratyphi A, with ISEcpl located on the upstream of it. Three muhidrugresistant strains of Salmonella all carried one 1 900 bp classⅠ integron gene cassette dhfrⅫ-orfF-aadA2,with the additional one β-lactamase gene of blaTEM-1, or blaOXA-30. Twenty-two distinct PFGE patterns were observed among twenty-five S. enterica typhi. The PFGE patterns of sixty-four S. enterica paratyphi A showed limited genetic diversity (average similarity of 91% ). Ninety investigated inpatients were infected in the community. Six patients infected by S. enterica paratyphi A had a travel history before infection. Conclusions Nalidixic acid-resistant S. enterica typhi and S. enterica paratyphi A are highly prevalent in Shenzhen,China. The mutation in the QRDR of GyrA is the prevalent mechanism responsible for the resistance to nalidixic acid in Slmonella. The great genetic similarity among S. enterica paratyphi A isolates indicates endemic disease from the presence of a single clone over 6-year period.

Objective:To evaluate the clinical value of the transcutaneous neuromodulation (TN) in improving gastrointestinal function after gastrointestinal tumor operation.Methods:From April 2019 to June 2020, at The Affiliated People′s Hospital of Ningbo University, 100 patients who underwent gastrointestinal tumor surgery were included. The 100 patients were randomly divided into treatment group(receiving TN treatment, 50 cases)and control group (receiving sham TN treatment, 50 cases). The clinical data of the two groups was compared to evaluate the recovery of gastrointestinal function, which included the time of first defecation, time of first flatus, time of first ambulation, time of resuming diet, the incidence of nausea and vomiting within 3 d after operation and pain score (0 to 10). Heart rate variability (HRV) was compared between two groups to analyze the possible mechanism of TN improving gastrointestinal function after gastrointestinal tumor surgery. Independent sample t test and Chi-square test were used for statistical analysis. Results:Among 100 patients, there were 63 male and 37 female patients, the age was (67.0±11.3) years old, ranged from 28 to 92 years old. Compared with the control group, the time of first defecation, first flatus, first ambulation and resuming diet of treatment group reduced by 31.0%, 39.8%, 38.0% and 32.4% ((72.1±3.0) h vs.(104.5±2.9) h, (49.4±5.7) h vs.(82.1±3.1) h, (3.1±0.7) d vs.(5.0±0.9) d, (4.8±0.9) d vs. (7.1±0.8) d)), respectively; the pain scores on the day 2 and day 3 after operation and incidence of nausea and vomiting within 3 d after operation decreased by 50.0%, 65.5%, 26.0%(1.5±0.6 vs. 3.0±0.7, 1.0±0.6 vs. 2.9±0.6, 16.0%, 8/50 vs. 42.0%, 21/50), respectively, and the differences were statistically significant ( t=54.28, 35.72, 11.67, 13.66, 12.00 and 14.90, χ2=8.21, all P<0.01). The results of HRV analysis showed that the high frequency on day 3 was higher than that on day 1 of treatment group, and the ratio of low frequency to high frequency after operation was lower than that before operation of treatment group (0.5±0.1 vs. 0.4±0.1, 1.2±0.7 vs. 1.9±1.0), and the differences were statistically significant( t=-4.81 and 4.26, both P<0.01), which indicated TN could enhance vagal activity. Conclusions:TN promote the recovery of gastrointestinal function after gastrointestinal tumor operation, and can be used as an adjuvant therapy to accelerate the recovery of gastrointestinal function after gastrointestinal tumor operation.
