OBJECTIVETo explore the effect of Sedum sarmentosum Bunge Extract (SSBE) on severe acute pancreatitis (SAP) induced acute lung injury (ALI) model rats and their excessive inflammatory reactions.

METHODSForty-two healthy adult male Sprague-Dawley (SD) rats were randomly divided into 3 groups, the sham-operated control group (C), the SAP group (SAP), and the SSBE treated group (SSBE), 14 in each group. SAP induced ALl rat model was induced by retrograde injection of 5% sodium taurocholate (1 mL/kg) into the pancreatic duct. SSBE (100 m/kg) was administrated subcutaneously after the establishment of the SAP model. Equal dose of SSBE was injected again 12 h later. Equal volume of normal saline was administrated in the same way for rats in the C group and the SAP group. Rats were sacrificed after successful modeling and samples taken at 12 and 24 h. Pathological changes in the pancreas and the lung tissue were observed under light microscope. The ascites, serum amylase (AMS), wet/dry proportion (W/D) of the lung tissue, activities of myeloperoxidase (MPO), interleukin-1 (IL-1), IL-6, and tumor necrosis factor-alpha (TNF-alpha) were also measured.

RESULTSAscites and serum AMS activities significantly increased; MPO, IL-1, IL-6, TNF-alpha contents, and W/D ratio also significantly increased in the SAP group, when compared with the C group (P<0.05). Compared with the SAP group, those parameters were all attenuated in the SSBE group at 12 and 24 h (P<0.05, P<0.01). Pathological changes in the pancreas and the lung tissue were alleviated in the SSBE group under light microscope. The injury degree ranged between that of the C group and the SAP group.

CONCLUSIONSSBE could relieve the ALl in SAP model rats, which could be achieved through alleviating inflammation responses of SAP rats.

Population pharmacokinetics of vancomycin (VAN) in the Chinese patients was described by using nonlinear mixed-effects modeling (NONMEM). 619 VAN serum concentrations data from 260 patients including 177 males and 83 females were collected separately from two centers. A one-compartment model was used to describe this sparse data. No significant difference was observed between two center datasets by introducing SID covariate. The final model was as CL= (θ (base0+ θ(max) x(1 -e(-θ(Age)(Age/72) and V = θ x θ (Age)(Age/72). The creatinine clearance (CL(Cr)) and Age were identified as the most significant covariate in the final model. Typical values of clearance (CL) and volume of distribution (V) in the final model were 2.91 L x h(-1) and 54.76 L, respectively. Internal model validation by Bootstrap and NPDE were performed to evaluate the robustness and prediction of the final model. The median and 95% confidence intervals for the final model parameters were based on 1000 Bootstraps. External model evaluation was conducted using an independent dataset that consisted of 34 patients to predict model performance. Pharmacodynamic assessment for VAN by AUC (0-24 h) to MIC ratios of over 400 was considered to be the best to predict treatment outcomes for patients. AUC (0-24 h) was calculated by clearance based on the above population model. The results indicate that the conventional dosing regimen probably being suboptimal concentrations in aged patients. The approach via population pharmacokinetic of VAN combined with the relationship of MIC, Age, CL(Cr) and AUC(0-24 h)/MIC can predict the rational dose for attaining efficacy.

OBJECTIVE: To explore the methods to assess the function disorder of patients with mild psychiatric impairment due to road traffic accidents. METHODS: In contrast to that of the patient with physical impairment, the function disorder of the patient with mild psychiatric impairment was assessed by the standard assessment instruments, such as the Barthel index of ADL (BI), Functional Activities Questionnaire (FAQ), Social Disability Screening Schedule (SDSS), Activity of Daily Living Scale (ADL), Physical Self-maintenance Scale (PSMS), and Instrumental Activities of Daily Living Scale (IADL). RESULTS: Except BI, the each total score of FAQ, SDSS, ADL, PSMS, and IADL correlated well with the rank of psychiatric impairment. The difference of each total score of rating scales among different physical impairment rank was not statistically significant. At the impairment rank of level 10, the difference of each total score of FAQ and ADL was not significant between the two groups; each total score of BI, SDSS, and IADL in psychiatric impairment was higher than that of physical impairment, while the total score of PSMS in psychiatric impairment was lower than that of physical impairment. At the level 9, except PSMS, the each total score of BI, FAQ, SDSS, IADL and ADL in psychiatric impairment was higher than that of physical impairment. At the level 8, except BI and PSMS, the each total score of FAQ, SDSS, IADL and ADL in psychiatric impairment was higher than that of physical impairment. CONCLUSION The different criteria for assessment of mild psychiatric and physical impairment may exist, and appropriate indexes for assessment between physical and psychiatric impairment need to be further elucidated.
