Objective To investigate the effects of serum isoenzyme and inflammatory factors by large doses of methyl prednisolone shocktherapy in the treatment of patients with acute hundred withered grass poisoned.Methods 46 cases of patients with acute hundred withered grass poisoned from June 2014 to October 2015 in ningbo medical center lihuili hospital were collected and randomly divided into two groups,23 cases in each group.On the base of the conventional treatment,patients in the control group were treated by blood perfusion therapy,patients in the experiment group were treated with large dose of methyl prednisolone shock therapy on the base of the control group,tested and compared the levels of serum enzyme and inflammatory factors before and after treatment,observed the clinical symptoms,clinical efficacy and adverse reactions.Results Compared with before treatment,the levels of IL-1,IL-10,TNF-αand CRP in two groups were decreased (P<0.05),levels of CK, CK-MB, TGF-β1 and HIF-1αdecreased (P<0.05);Compared with the control group,the levels of IL-1,IL-10, TNF-αand CRP in the experiment group were lower (P<0.05);CK,CK-MB,TGF-β1 and HIF-1αlevels were lower (P<0.05),after treatment from the last row of green time,the plasma PQ clearance time and length of hospital stay were shorter (P<0.05),total effective rate was higher (P<0.05).Conclusion Large doses of methyl prednisolone shock therapy in the treatment of patients with acute hundred withered grass poisone has definite clinical efficacy , can reduce the patients’serum CK,CK-MB,TGF-β1,HIF-1αand inflammatory factors levels, with higher security.

Objective To observe curative effect of acupuncture treating children acute upper respiratory infections (AURI).Methods According to random digits table,150 children from clinic emergency department were averagely bring into a acupuncture treatment group and a western medicine treatment group.Patients in the acupuncture treatment group received the treatments of acupunctureing one side of “SiGuan”points,bloodletting in apex satyri,and reducing temperature with tepid sponge bath; while patients in the western medicine treatment group received the treatments of taking ibuprofen suspension,using external pyretolysis patches on forehead,and reducing temperature with an alcohol sponge bath.After the treatment,the near future therapeutic effects:the time of pyretolysis,fevering again in 24 hours and convulsion time,and the prostecdtive efficacy:the time of cough continuing,AURI happening again in 3 months and recovery time of appetite were both observed.Results The time of pyretolysis,fevering again in 24 hours,convulsion time,the time of cough continuing,recovery time of appetite and AURI happening again in 3 months of acupuncture treatment group was(15.6±5.8) minutes,(12.7±3.3) hours,(0.6±0.1) times,(2.3±1.8) days,(2.4±1.6)days,and (35.2±3.9) days respectively; and the western medicine treatment group was (25.5±7.3) minutes,(8.6±4.1) hours,(2.1±0.5) times (6.2±2.4) days,(3.8±1.5) days,and (18.4±5.2) days respectively.Comparing between the two groups,P＜0.05.Conclusion Acupuncture can significantly decrease the time of pyretolysis,cough continuing,recovery time of appetite and convulsion time,and significantly increase the time of fevering again in 24 hours and AURI happening again in 3 months in patients with AURI.

BACKGROUND: At present, there is little related report about producing a whole-kidney acellular matrix (ACM) scaffold in rats using perfusion. The cellular biocompatibility of the ACM is poorly understood. OBJECTIVE: To produce a whole-kidney ACM scaffold in rats by perfusion, to evaluate the cytocompatibility of ACM with the L929 cells in vitro, and to assess the possibility of ACM as the cytoskeleton and tissue-engineered urinary organ construction. DESIGN, TIME AND SETTING: An in vitro observation was performed at the Central Laboratory of Zhujiang Hospital, Southern Medical University from February to May 2009. MATERIALS: Kidneys were obtained from 12-week-old Whista rats, while ureter, renal veins and renal artery were reserved. Intravenous catheters were inserted through renal arteries to establish channels for perfusion. Whole-kidney retrograde perfusion was performed with successively heparinized PBS, 1% SDS, deionized water, 1% TritonX-100 and antibiotic-containing PBS under a pressure of 9.81 kPa to prepare whole-kindney acellular matrix scaffolds. METHODS: ① Samples were randomly divided into blank group (without any cells), negative control group (culture media), experimental group (rat kidney ACM leaching liquor), and positive control group (culture media containing 0.64% phenol). L929 cells in the logarithmic phase were seeded in 96-well plates at the density of 4×10~3/well, with 5 wells in each group. At 24, 72, and 120 hours after incubation, cells were stained with MTT method to detect absorbance at 490 nm and calculate relative growth rate. ② Control group (culture medium), experimental group (rat kidney ACM leaching liquor), and positive control group (culture media containing 0.64% phenol) were set up to detect cell apoptosis at 48 hours after culture using flow cytometry. MAIN OUTCOME MEASURES: Microstructure of the scaffold, cytotoxicity and cell apoptotic rate. RESULTS: After SDS and TritonX-100 union processing, reticulate structures made of basilar membrane and collagen were shown under scanning electron microscope rather than normal structures of cells. At every time intervals (24, 72, and 120 hours), there was no significant difference in the absorbance between experimental group and negative control group (P > 0.05). The grade of the cytotoxicity of the ACM was .0-1. There was no significant difference in cell apoptotic rate between experimental group and negative control group (P > 0.05). CONCLUSION: The whole-kidney acellular matrix scaffolds in rat by perfusion have good biocompatibility.

Objective To investigate the effects of ultra-filtration extract from the mixture of Angelicae Sinensis Radix and Hedysarum Polybotrys (UFE-AH) on the expressions of HSP70 and eNOS in H2O2-induced endothelial cell apoptosis. Methods H2O2 induced ECV-304 cell apoptosis to prepare models. The experiment was divided into normal control group, model group, simple medicine group, medicine intervention group, and all treatment groups received relevant medicine for intervention. Flow cytometry (FCM) was used to detect apoptosis and concentration of intracellular Ca2+;RT-PCR was used to detect the mRNA expression of HSP70 and eNOS;Western blot was used to detect the expression of HSP70 protein;Nitrale reduetase and spectrophotometric method were employed to detect the content of NO. Results Compared with normal control group, cell apoptosis rate, concentration of intracellular Ca2+, and expression of HSP70 increased significantly in model group (P<0.05);gene expression of eNOS mRNA and content of NO decreased (P<0.05). Compared with model group, cell apoptosis rate and concentration of intracellular Ca2+dropped in medicine intervention group (P<0.05);expressions of HSP70, eNOS mRNA and content of NO increased (P<0.05). Conclusion UFE-AH can confront H2O2-induced cell apoptosis H2O2 of ECV-304 human umbilical vein endothelial by increasing the expressions of HSP70 and eNOS and content of NO, and reducing the intracellular calcium overload.
