Objective To investigate the therapeutic effect of traditional Chinese medicine(TCM)recipe of nourishing kidney and activating blood for treatment of cisplatin induced acute kidney injury(AKI)in mouse model. Methods Twenty-one male BALB/c mice were randomly divided into three groups:control group,AKI model group and treatment group with the above TCM recipe(each n=7). The AKI model was reproduced by a single intraperitoneal injection of cisplatin 20 mg/kg;the TCM recipe with dosage of 10μL · g-1 · d-1 was given to the treatment group,while equal volume of normal saline was given to the model and control groups by gavage,lasting for 6 days in all groups. The changes of each mouse body weight were observed;mouse venous blood serum creatinine(SCr)level was detected,changes of renal tissue weight and its histopathology were observed under light microscope,and the score of acute tubular necrosis(ATN)was calculated. Results Compared to the control group,the body and renal weight in AKI model group were significantly lowered〔body weight(g):17.18±0.29 vs. 19.33±1.43,renal weight(g):0.28±0.01 vs. 0.32±0.11,both P<0.01〕,and SCr and ATN scores were significantly increased in AKI model group〔SCr(μmol/L):86.77±10.97 vs. 14.37±0.81,ATN score:3.33±0.52 vs. 0.17±0.41,both P<0.01〕. Compared to AKI model group,the body weight(g:18.70±0.28)and renal weight(g:0.31±0.01)in the treatment group were markedly increased,and SCr(μmol/L:21.98±5.52)and ATN scores(2.00±0.63)were significantly lower than those of the AKI model group(all P<0.01). Under optical microscope,there were mouse renal tubular epithelial cell edema and necrosis,renal interstitial inflammatory cell infiltration,the glomerular form roughly normal in the AKI model group;compared with the AKI model group,in the treatment group the degree of mouse renal tubular necrosis was significantly reduced and glomerular form was basically normal. Conclusion The TCM recipe of nourishing kidney and activating blood can reduce SCr and improve the pathological changes of renal tissue in cisplatin induced AKI mouse models,thus it has therapeutic effect for treatment of AKI in mice.

Objectlve To investigate the effects of sevoflurane or ischemic preconditioning on the expression of extracellular signal-regulated kinase (ERK) and calmodulin (CaM) during lung ischemia-reperfusion (I/R)in rats. Methods Twenty-four male SD rats weighing 270-320 g were randomly divided into 4 groups ( n = 6each): sham operation group (group S), group I/R, ischemic preconditioning group (group IP), and sevoflurane preconditioning group (group SP). In group S, the hilum of the left lung was dissociated after thoracotomy but not occluded. In group I/R, lung I/R was produced by occlusion of the hilum of the left lung for 45 min followed by 120 min of reperfusion. In group IP, the hilum of the left lung was occluded for 5 min and unclamped for 5 min for 2 times before the model was established. In group SP, sevoflurane was inhaled for 30 min at the end-tidal concentration of 2.1% before lung ischemia. All rats were sacrificed at 120 min of reperfusion and the lung tissues were taken for determination of the contents of TNF-α and IL-6 by ELISA and the expression of ERK mRNA and CaM mRNA by RT-PCR. Results Compared with group S, the contents of TNF-α and IL-6 and the expression of ERK mRNA and CaM mRNA were significantly increased in group I/R, IP and SP ( P < 0.05). Compared with group I/R, the contents of TNF-α and IL-6 and the CaM mRNA expression were significantly decreased, while the expression of ERK mRNA was significantly increased in group IP and SP ( P < 0.05). There was no significant difference in the each index metioned above between group IP and SP ( P > 0.05 ). Conclusion Sevoflurane preconditioning and ischemic preconditioning can protect the lung from I/R injury through down-regulating the expression of CaM and up-regulating the expression of ERK.

Background and purpose:Radiomics is an emerging field that generates large amounts of valuable clinical information through extracting quantitative imaging features. The purpose of this study was to use the radiomics approach to assess the value of features captured from PET and CT in predicting the therapeutic effect in stageⅠ non-small cell lung cancer (NSCLC) after stereotactic ablative radiotherapy (SABR).Methods:Patients with stageⅠ NSCLC conifrmed by pathology and treated with SABR were included retrospectively. The gross tumor volume (GTV) was deifned by two radiologists. PET and CT scan images were collected, and radiomic features were further extracted and analyzed. Non-negative matrix factorization was used to distinguish patients with or without local control.Results:Sixteen patients were eligible for analysis. This study identiifed two PET features (LL_GLCM_Maximal_Correlation_Coeffcient and HL_GLRMS_LRE) captured from PET/CT as having signiifcance in classifying patients with or without disease development. This study not ifnd similar results in CT scans.Conclusion:It seems feasible to use radiomics information effects from PET/CT to predict therapeutic effects of SABR in stageⅠ NSCLC. Further investigation is needed.
