RESUMO
OBJECTIVE To explore the material basis and potential mechanism of Kazakh classic prescription Wuzdekh （WZDK） in the treatment of enteritis. METHODS LC-MS/MS technology was used to analyze the chemical components in WZDK. Through network pharmacology and molecular docking technology， the main chemical components of WZDK were screened and the target was predicted； therapeutic effect and target of WZDK on acute enteritis were verified through in vivo experiments. The acute enteritis model of mice was induced by dextran sulfate sodium salt； the general condition of the mice was observed during administration and the disease activity index （DAI） score was calculated； pathological changes of the intestine and mRNA expression of core target were validated by HE staining and quantitative real-time PCR. RESULTS A total of 316 chemical components were obtained by LC-MS/MS. The core targets of network pharmacological analysis mainly included interleukin 1β（IL- 1β）， protein kinase B1 （AKT1）， tumor protein p53 （TP53）， IL-6， tumor necrosis factor （TNF） and so on. The results of molecular docking showed that chemical components such as mairin， lappadilactone， costunolide and dehydrocostus lactone were stable in binding to the core target. The results of in vivo experiment showed that， compared with model group， high dose （5.00 g/kg） of WZDK could significantly reduce the DAI score （P＜0.05）， improve inflammatory cell infiltration and mucosal tissue damage of colon tissue， and significantly down-regulated mRNA expressions of IL-6， TNF-α， IL-1β and TP53 in colon tissue（P＜ 0.05 or P＜0.01）. CONCLUSIONS Chemical components of WZDK such as mairin， lappadilactone， costunolide and dehydrocostus lactone may play the role of improving the imbalance of local inflammatory factors in the intestine and repairing damage of colonic mucosal tissue by down-regulating mRNA expressions of TNF-α， IL-6， IL-1β and TP53 in colon tissue.
RESUMO
Objective To summarize the CT features of pulmonary mucormycosis in post hematopoietic stem cell transplantation (HSCT) patients with leukemia,to provide timely and accurate guidance for clinical treatment.Methods 9 pulmonary mucormycosis in post HSCT patients with leukemia confirmed by surgery,biopsy and sputum culture were analyzed retrospectively.Distribution,morphology and CT features of the disease were analyzed and summarized.All patients were underwent non-enhanced MSCT.Results Reversed halo sign (n=7);patchy ground glass opacity (GGO) (n =5);bilateral multiple pulmonary nodules and nodular GGO (n=3);bilateral multiple pulmonary micro-cysts with spiculate boundary (n=1);pleural effusion (n=2);pneumo-mediastinum (n 1) were seen.Two or more than two CT signs were seen in some patients.The interval time between the appeared reversed halo sign and the transplantation were 0.5-19 months in 7 patients,which median time was 10 months and 6 cases (85.7％) appeared within 18months.8 patients (88.9 ％) presented cough,expectorated white or yellow phlegm,among them,4 cases (50 ％) presented bloodstained sputum or hemoptysis.3 cases (37.5 ％) presented left chest pain.1 case was asymptomatic.6 patients (66.7 ％) presented significant increased body temperature with the range from 38.4 ℃ to 39.6 C,the median was 39 C.3 patients (33.3％) showed normal temperature.The WBC counting was between 0.16-3.31 × 109/L,the median was 0.7 × 109/L.The neutrophil cell counting was between 0-2.46 × 109/L,with the median of 0.09 × 109/L.Among them,7 patients (77.8％) found reversed halo sign with neutrophil counting between 0-1.63 × 109/L,and the median was 0.09 × 109/L.Conclusion Various imaging manifestations of pulmonary mucormycosis are seen in post HSCT patients with leukemia.When patients is in agranulocytosis phase after transplantation HSCT,it is highly suggested pulmonary mucormycosis infection when the characteristic reversed halo sign is found.
RESUMO
Objective To summarize the MRI manifestations of immunosuppressive drugs associated encephalopathy after allogeneic hematopoietic stem cell transplantation (allo-HSCT) in children with aplastic anemia. Methods Fifteen patients with immunosuppressive drugs associated encephalopathy after allogeneic hematopoietic stem cell transplantation for aplastic anemia during January 2014 to October 2016 were analyzed retrospectively. There were 7 males and 8 females, aged from 3 to15 years old, with the median age of 7 years old. Ten cases presented dizziness and headache while other 4 cases presented blurred vision, blind and gaze. Only one case suffered from seizure and loss of consciousness. MRI patterns including distribution, morphology and signal intensity were analyzed after treatment. Follow up MRI were performed after reducing drug dose and symptom remission. The duration of immunosuppressive drugs associated encephalopathy of the 15 cases were 1-14 months, with 6 months in 9 cases. Results Focal lesions were found in 11 cases, in which the deep nuclei were involved in one case and the white matter was involved in 10. Four patients showed both cerebral cortex and white matter lesions, including cerebellum and brainstem invasion in one patient. No corpus callosum lesions were found. Various degree of brain atrophy was found in all patients. Cortical lesions showed swelling and involved subcortical white matter presented as arc shape or strip-like lesions. Patchy patterns were found in deep white matter. Thin layer shaped lesions were found in the periventricular white matter. Small flake-like lesions were found in the brain stem and the cerebellum. The lesions showed hypointensity on T1WI, equal or high signal on T2WI. T2WI FLAIR showed equal or high signal;DWI in the cortex and subcortical white matter lesions showed iso-or high signal, while other lesions were isointense. Eight cases acquired clinical relief in short term without obvious improvement on MRI image. Both clinical symptoms and imaging findings improved in 6 cases. One case showed clinical relief but progression on MRI. Conclusions MRI is an effective way to find immunosuppressive drugs-related encephalopathy in children with aplastic anemia after allogeneic hematopoietic stem cell transplantation. It can help the diagnosis and provide the information for clinical treatment.
