ABSTRACT
Objective To investigate the effect of section of pancreatic envelope combined with vacuum sealing drainage under laparoscopy on inflammatory mediators of patients with early severe acute pancreatitis (SAP). Methods Forty-two SAP patients were admitted to Foshan Hospital of Traditional Chinese Medicine in Guangdong Province from January 2008 to December 2016. That 22 patients underwent pancreatic membrane incision and vacuum sealing drainage under laparoscopy was in the experimental group, and that 20 patients underwent the routine pancreatic membrane incision and double tube drainage was in the control group. The venous blood was collected, the levels of C-reactive protein (CRP), interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) were measured before and after operation for 1, 3, 7 and 14 days, and the clinical therapeutic effects were observed in the two groups. Results With the prolongation of therapy, the levels of CRP, IL-6 and TNF-α were decreased continuously in both groups, the degrees of decrease of above indexes in experimental group were more significant than those in the control group, and the differences in these indexes between the two groups were statistically significant [CRP (mg/L): 1 day was 203.80±25.12 vs. 271.79±60.41, 3 day was 117.26±19.70 vs. 174.53±42.37; IL-6 (ng/L): 1 day was 40.63±3.38 vs. 57.10±11.46, 3 days was 23.14±3.51 vs. 46.87±10.69; TNF-α (ng/L): 1 day was 23.91±10.42 vs. 36.73±15.90, 3 days was 19.13±8.34 vs. 32.58±15.81, all P < 0.05]. There were no statistical significant differences in the levels of above indexes on 7 days and 14 days after treatment between the two groups (all P > 0.05). The therapeutic efficacy of the experimental group was significantly higher than that of the control group [95.45% (21/22) vs. 90.0% (18/20), P < 0.05]. Conclusion Under laparoscopy, pancreatic envelope incision combined with vacuum sealing drainage performed for early SAP patients can control the body inflammation more rapidly, reduce complications and shorten the disease course.
ABSTRACT
To investigate the contamination conditions of Campylobacter spp.in duck production chain and its antimicrobial resistance,virulence gene distribution,samples were collected at the duck slaughterhouse according to GB 4789.9-2014.Triplex PCR assay was applied to identify the species of Campylobacter and the recovered Campylobacter strains were tested for the antimicrobial susceptibility against 8 kinds of antimicrobial agents using a broth microdilution method,the susceptibility results were determined according to the NARMS criteria (2011).Subsequently,4 virulence genes were detected by PCR method.The result showed that 187 Campylobacter isolates were obtained from 489 samples,including 160 C.jejuni,130 C.coli and 10 unidentified Campylobacter isolates.The total isolation rate of Campylobacter was 38.24％.The prevalence of Camnpytobacter before slaughtering,at depilation stage,evisceration stage and duck products was 76.33％,5.62％,24.00％,and 0％,respectively.The Campylobacter isolates were most frequently resistant to tetracycline (95.72 ％),followed by resistance to clindamycin(90.91％),the resistance rate of azithromycin (63.64％) was in the middle,the resistance rates of ciprofloxacin(31.02％),gentamicin(34.76％),nalidixic acid (37.43 ％),erythromycin (41.18 ％),chloramphenicol (41.18％) were relatively low.The multi-drug resistance was common among Campylobacter isolates with a rate of 72.19％.The prevalence of adhesion-associated gene cadF,flagellin gene flaA,invasion associated protein gene iamA,toxin regulation gene cdtB was 100％,80.75 ％,71.12％ and 94.65％,respectively.The results indicated that the Campylobacter contamination occurred in the slaughtering procedures of duck,and the antimicrobial resistance of Campylobacter isolates was relatively serious.In addition,the virulence-associated genes were detected widely among Campylobacter isolates.Therefore,the supervision of antimicrobial agents using at rearing stage should be strengthened,along with health management in duck production chain.
ABSTRACT
Objective To investigate the antimicrobial resistance and resistance profiles of Salmonella isolates,from the pork production chain in several districts of Sichuan province and to determine the correlation between serotype and the pulse field gel electrophoresis(PFGE)patterns. Methods From 2010 to 2011,a total of 112 Salmonella isolates from pork production chain were examined for their antimicrobial susceptibility,using the micro-dilution method against 10 antimicrobial agents. Results were assessed by the standard by the Clinical and Laboratory Standards Institute (CLSI,2010). In addition,PFGE patterns were investigated among the Salmonella strains from different sources,under different serovars and antimicrobial profiles. Results For Salmonella isolated from the pork production chain,resistance to tetracycline(89.29%)was frequently observed. Many isolates were resistant to spectinomycin(36.61%),trimethoprim/sulfamethoxazole(35.71%), nalidixic acid(33.93%)and ampicillin(24.11%),but all of the isolates were susceptible to ceftiofur. 33.93% of the isolates were multi-drug resistant. Salmonella isolates from the pork production chain had 19 antibiotic resistance profiles. Totally,34 PFGE patterns were detected among 74 Salmonella isolates from the pork production chain,with the PFGE patterns of the 74 Salmonella isolates sharing 40%to 100%similarities. Conclusion The antimicrobial resistances of the Salmonella isolates were commonly detected from the pork production chain in Sichuan province suggesting that Salmonella might horizontally spread from food animals to retail meat products.

BACKGROUND: Hanshibi granule indicates rheumatism due to blockage of cold and damp.OBJECTIVE: To observe the effects and safety of intervention of hanshibi granule on rheumatism due to blockage of cold and damp and the comparative observation was carried on by taking zhengqingfengtongning as the control drug.DESIGN: Case randomized-controlled observation was designed.SETTING: Luoyang Bone-setting Hospital of Henan Province.PARTICIPANTS: Totally 400 cases of rheumatism due to blockage of cold and damp visited in Luoyang Orthopedic Hospital of Henan Province were volunteered in the observation from May 2000 to February 2002.Hanshibi granule was composed of fuzhi (Radix Aconiti Praeparata),huangqi (Radix Astragali), weilingxian (Radix Clematidis), more than 10 herbs, 10 g each bag. Zhengqing fengtongning tablet is 20 mg each tablet.METHODS: Based on the randomization and sequence of visiting, the cases were divided into observing group and the control at the ratio of 3:1.In the observing group, hanshibi granule was administrated, 1 bag/time,3 times/day, infused with water. In the control, zhengqing fengtongning tablet was administered orally, 2 tablets/time, 3 times/day; 1 week later,if there was no harmful reaction, it was administered 3 tablets/time,3 times/day. For rheumatic arthritis (RA) and ankylosing spondylitis (AS),the drugs were taken for 2 months as 1 course, and for knee osteoarthritis,the drugs were taken for 1 month as 1 course. The changes of ESR, C-reactive protein (CRP) and rheumatic factor (RF) and uric acid (UA) were determined and recorded. Criteria on evaluation: ① Evaluation on therapeutic effects on syndromes: Remarkable effect: the symptoms were improved remarkably after treatment and symptom integral was 0-1 score or decreased by ≥ 2/3. Effect: the symptoms were improved after treatment and the symptom integral was decreased by≥1/3.② Evaluation on therapeutic effects on symptoms: Remarkable effect: The symptom integral was reduced to 0 score or reduced by 2 scores after treatment, such as joint pain, swelling, tender pain, morning stiffness and functional impairment. Effect: the integral was reduced by 1 score after treatment. ③ Evaluation on total therapeutic effects on diseases: Remarkable effect: the symptoms and physical signs disappeared basically, the main laboratory indexes were improved remarkably and reduced by ≥ 50%. Effect: The symptoms and physical signs were alleviated and the main laboratory indexes were improved.MAIN OUTCOME MEASURES:① Total clinical therapeutic effect,therapeutic effect on different symptoms and diseases between two groups.②Safety of hanshibi granule.RESULTS: Totally 400 cases were employed, of which, 300 cases were in observing group and 100 cases in the control. In observing group, 19 cases were dropped out and 281 cases were in the statistics. In the control,6 cases were dropped out and 94 cases were in the statistics.①Comparison of total clinical therapeutic effects between two groups: The total effective rate in the observing group was higher significantly than that in the control (94.31％, 84.04％, P ＜ 0.01). ② Comparison of therapeutic effects on different symptoms between two groups: There was no significant difference in the therapeutic effects on joint pain, swelling,tender pain, functional disturbance and morning stiffness between two groups (P ＞ 0.05). ③ Comparison of therapeutic effects on different diseases between two groups: There was no significant difference in the therapeutic effects on RA, AS and knee osteoarthritis (P ＞ 0.05). ④ Safetyof hanshibi granule: abnormal urine routine for a part of cases before treatment was improved after treatment. ST-T wave alternation in ECG for a part of cases before treatment was not aggravated obviously after medication.CONCLUSION: Both hanshibi granule and zhengqingfengtong tablet, the control drug improves significantly joint pain, swelling, tender pain, functional impairment and morning stiffness in rheumatism due to blockage of cold and damp, in which, the effect of intervention of hanshibi granule is superior to that of the control drug, without obvious harmful reactions;therefore, such drug can be taken as a safe and effective one for rheumatism due to blockage of cold and damp.
