RESUMEN
OBJECTIVE:To investigate the pathogen distribution and drug resistance situation in bronchoalveolar lavage fluid (BALF) from patients with refractory pulmonary infection,and provide reference for clinical rational drug use. METHODS:The sputum and BALF specimen of 136 inpatients with refractory pulmonary infection from the First People’s Hospital of Zhenjiang City from Jan. 2012 to Dec. 2015 were cultured and identified,pathogen detection was compared,and results of drug sensitivity test for pathogen in BALF specimen was analyzed. RESULTS:The positive rates of sputum and BALF specimen of 136 inpatients were 22.06%and 47.79%,with statistical significance(P<0.01);a total of 32 and 72 strains were isolated,they mainly were Ste-notrophomonas maltophilia,Pseudomonas aeruginosa,Acinetobacter baumannii and Staphylococcus aureus. S. maltophilia in BALF was sensitive to minocycline and levofloxacin;resistance rate of P. aeruginosa to common antibiotics was lower than 50%;A. baumannii was sensitive to imipenem,ampicillin sodium and sulbactam sodium,amikacin and minocycline;S. aureus was sen-sitive to linezolid,chloramphenicol and vancomycin. CONCLUSIONS:The positive rate of BALF specimen is higher than spu-tum,the pathogens are mainly Gram-negative bacteria. Clinic should rationally select antibiotics based on the drug sensitivity test and clinical symptoms.
RESUMEN
Recent studies have found that peptide therapies tar-geting specific epitopes can avoid nonspecific immune suppres-sion induced by traditional medicines for the treatment of autoim-mune diseases, and have shown great therapeutic effect in ani-mal models of autoimmune diseases and clinical trials. The pa-per summaries the research progress and trends of peptide drugs for the treatment of autoimmune diseases from candidate peptide sources and their suppression mechanisms, which can provide a theoretical basis for the in-depth understanding of immune toler-ance and allow for discovery of new treatment for autoimmune diseases.
RESUMEN
OBJECTIVE:To provide reference for the prevention,diagnosis and treatment of drug eruptions in the clinic. METHODS:A total of 102 drug eruption cases from 1998 to 2007 in our hospital were analyzed in respect of the allergizing drugs and the types and the clinical features of the drug eruptions. RESULTS: The drug eruptions were mostly induced by antimicrobials (45 cases),followed by antipyretic analgesics (15 cases) and Chinese medicines (15 cases). Erythema polymorphe (39 cases) was the most common clinical type,followed by urticaria (18 cases) and fixed erythema (15 cases). CONCLUSION: Clinician should attach great importance to patients' drug allergic history and medication history so as to reduce the incidence of drug eruption.
RESUMEN
OBJECTIVE:To study the general pattern and characteristics of adverse drug reactions(ADR) induced by tinidazole.METHODS:Tinidazole-induced ADR cases reported in the internal pharmaceutical journals retrieved from Jan.1994 to Jun.2006 were analyzed statistically.RESULTS:The ADR induced by tinidazole were diversified in clinical manifestation,but allergic response was the most common type,followed by the lesion of nervous system and digestive system etc.CONC-LUSION:Clinicians should attach great importance to the ADR induced by tinidazole.
RESUMEN
Aim To study the preventive and therapeutic effects of total flavonoids of Litsea Coreana level on nonalcoholic steatohepatitis in rats.Methods 48 SD rats were randomized into control,model,NA,TFLC(50,100,200 mg?kg~(-1))groups(n=8).The control group were only fed with a standard diet and the other groups were fed with a standard diet and fat emulsion(10 ml?kg~(-1));At the same time,the control and model groups were fed with CMC-Na,the other groups were fed with relative medicine.The stool TG,TC,the serum TG,TC,ALT,AST,MDA,SOD and hepatic TG,TC,MDA,SOD were detected dynamically.Results The model group developed NASH after 3 weeks.NA and TFLC(100,200 mg?kg~(-1))significantly reduced TG of the serum and liver tissue,and ameliorated hepatocellular macrovesicular steatosis.TFLC(200 mg?kg~(-1))markedly inhibited increased MDA in serum and liver tissue,and also elevated SOD in liver tissue.Conclusions TFLC markedly reduced the TG level of serum and liver tissue.Liver histopathological examination showed TFLC ameliorated hepatocellular macrovesicular steatosis.The protective and therapeutic effects of TFLC on NASH may be associated with inhibitory effect of fat absorption and lipid peroxidation.
RESUMEN
AIM To establish the hyperlipidemia and hyperlipidemic fatty liver animal model.METHODS 30 SD rats were randomized into control group (n=10)and model group(n=20).The rats of model group were fed with a standard diet and fat emulsion( 10 ml?kg -1);while the rats of control group were only fed with a standard diet.The serum TG,TC,ALT,AST,MDA,SOD and hepatic TG,TC,MDA,SOD were detected dynamically and with histologically.RESULTS The model group developed hyperlipidemia which TG and TC were elevated significantly after 1 week. 10 rats which were selected randomly in the model group were killed and the serum and liver were obtained after 2 weeks. The serum TG,TC,ALT and hepatic MDA of the model group rats were higher than the control's,while the hepatic SOD were lower. At the same time,the light degree hepatic steatosis of 2 rats were induced.The third week,both control group and model rats(n=10) were killed and the serum and the liver were obtained. Compared with the control group, the serum TG,TC,ALT,AST,MDA?SOD and hepatic TG,MDA of the model group rats were markedly higher, while the serum SOD and the hepatic SOD were significantly lower.The histopathology research showed hepatocellular macrovesicular steatosis and hepatitis in the model group. CONCLUSINOS The experimental animal model of hyperlipidemia and hyperlipidemic fatty liver in rats were successfully established for 1 week and 3 weeks fed with fat emulsion.
