ABSTRACT
AIM To study the pharmacodynamics of Baijin Granules [Mallotus apelta (lour.) Muell.Arg.,Smilax china L.],Zhuang medicine,on model rats with sequelae of pelvic inflammatory disease.METHODS The rat model for sequelae of pelvic inflammatory disease was built with mixed bacteria (Escherichia coli and Staphylococcus aureus) and mechanical injury.Subsequently,the rats were randomly divided into eight groups,including model,Baijin Granules low-,middle-,high-dose,positive control (dexamethasone and Huahong Granules),blank control and sham operation groups,with ten rats in each group.After 14 days of successive administration,the hemorheology and blood routine in rats' abdominal aorta were measured by collecting blood in 24 hours of last administration.The pathological morphology of uterine tissue was observed.RESULTS The hemorheology indexes,WBC count and neutrophil percentage were significantly decreased in the model rats,and the pathological morphology of uterine tissue was markedly improved.CONCLUSION Baijin Granules have good therapeutic effects on sequelae of pelvic inflammatory disease in rats.
ABSTRACT
Objective To explore the distributions and clinical characteristics of pathogenic bacteria in SAP patients with secondary infection.Methods We collected clinical data from SAP patients with secondary infection,to analyze the source of samples,pathogenic bacteria and its resistance to commonly used antimicrobial agents.Results (1) Samples Source:A total of 156 positive specimens were obtained,with the largest number from sputum samples (46.79％);The blood samples (70.59％) were collected most within 1 week,sputum samples (64.38％) from 1 week to 2 weeks,and pancreatic necrotic tissues or peripancreatic fluid samples (51.79％) after 3 weeks,with statistically significant differnces.(2) Pathogenic bacteria:156 strains were isolated including 86 strains (55.13％) of gram-negative bacteria (55.13％),of which acinetobacter baumannii and escherichia coli were the most commonly seen,followed by gram-positive bacteria of 41 strains (26.28％),and then fungus of 27 strains (18.59％).(3) Drug resistance:There was a high tolerance rate of commonly used antimicrobial agents,and the drug resistance rate of cinetobacter baumannii to carbapenems antibiotics was 88.00％.Conclusions SAP combined with secondary infection is mainly caused by gram-negative bacteria,and there is a high proportion of multidrug-resistant bacteria.Selecting suitable antimicrobial agents according to bacterial culture is beneficial for the early control of infections.
