Objective To investigate the regularity and clinical significance of cortisol(Cor),adrenocorticotrophic hormone(ACTH),atrial natriuetic peptide(ANP) and interleukin-6(IL-6) changes before and after operation stress.Methods The ACTH,Cor,ANP and IL-6 levels in 18 children with abdominal neoplasms(12 male and 6 female,8 cases with sacrococcygeal teratoma,5 cases with hepatoblastoma,and 5 cases with nephroblastoma) were measured before and after operation(24 hours before operation;4,24,48,and 72 hours after operation).Eighteen children were divided into the study group and the control group.The children in the former group were accompanied with stress ulcer,intestinal obstruction and infection shock or even death after operations,while the children in the later group recovered without any complication.The ACTH,Cor,ANP in serum were measured by radioactive immune analysis(RIA) assay,and serum IL-6 level were measured by enzyme linked immunosorbent assay(ELISA).Results In 2 groups,serum levels of ACTH,Cor,ANP,IL-6 increased significantly 4 h after operation.The changes in ACTH and ANP were similar in 2 groups.Cor in the control group reached its peak 24 h after operation,and then decreased gradually to the pre-operation levels 72 h after operation;IL-6 reached its peak 4 h after operation,and then decreased slowly.It was still at a high level in 48 h after operation,and then decreased to pre-operation levels 72 h after operation.But serum Cor,IL-6 in the study group slightly increased 24 h after operation,and were apparently higher than those in the control group(Pa

ObjectiveTo investigate the role of vascular endotheliar growth factor(VEGF),chemokine receptor 4(CXCR4) and stromal cell-derived factor-1(SDF-1) in Wilms tumor as well as their relationship with clinical features by examining the expressions of VEGF,CXCR4 and SDF-1.MethodsThirty cases of Wilms tumor samples and 12 cases of adjacent kidney tissue were collected from the First and the Third Affiliated Hospital of Zhengzhou University from May 2003 to May 2008.Thirteen boys and 17 girls aging from 4 months to 7 years old of whom were 22 favorable histologic types and 8 unfavorable histologic types.By means of cytoplasm to dye buffy for masculine cell,staining intensity and percentage of positive tumor cells serve as the judgment criteria for being positive or negative.All tissues would be tested by hematoxylin and eosin stain at the same time.ResultsThe positive expression rate of VEGF,CXCR4 and SDF-1 in Wilms tumor were 63.33%,70.0% and 53.33%.Those in adjacent normal kidney tissue were 25.0%,8.3% and 16.7%.The 2 groups were statistically significant(Pa

Objective To explore the hemostatic mechanism of micron rhubarb charcoal(MRC) for the treatment of gastric ulcer bleeding.Methods Both Kunming mice and SD rats were used as the experimental animals,and were randomized into blank control group,Yunnan white powder(9g?kg-1?d-1)group,and high-,middle-and low-dose MRC(8,4 and 2g?kg-1?d-1)groups,respectively,ig for 6 days.After treatment,bleeding time(BT),coagulation time(CT),and platelet count in mice were detected,and the platelet function and fibrinolytic activity in rats were examined.Results In mice MRC groups,BT and CT were shortened(P

Objective To explore the inhibition effect of interleukin-10(IL-10)on pneumonic anaphylacticitis in mice with asthma and its effects on the level of serum IgE.Methods Thirty BALB/c male mice whose weight were(20?2)g were randomly divided into 3 groups:normal group(n=10),asthma model group(n=10)and IL-10 treatment group(n=10).Asthma model group and IL-10 group were sensitized with 1 g?L-1 ovalbumin,then asthma model was made with inhallating 10 g?L-1 VOA 20 mL.The normal group was not administered anything as a negative group.Before inhallating with 10 g?L-1 VOA,asthma model group was administered inhalation with 9 g?L-1 saline 0.1 mL,and IL-10 treatment group was administered inhalation with 0.1 mL IL-10 whose concentration was 0.2 ?g?L-1.The level of IgE was measured by ELISA reagent box,eviscerated lungs after collecting blood and then made them into pathological slices.Results There was an obvious distinction in the mice pathological change of lungs and bronchus between asthma model group and other groups,but no significant difference between IL-10 treatment group and normal group.There was no obvious infiltration of inflammatory cells in the airways of IL-10 treatment group and normal group.However,there were a great number of inflammatory cells in the interstitial and peribronchovascular regions of asthma model group.The levels of serum IgE were(5.219?0.427)?g?L-1,(6.633?0.145)?g?L-1 and(5.503?0.566)?g?L-1 in normal group,asthma model group and IL-10 treatment group,respectively.The level of serum IgE in asthma model group increased obviously compared with normal group and IL-10 treatment group,with significant differences(Pa0.05).Conclusions Inhalation of IL-10 can optimally control the pneumonic anaphylacticitis,improve the situation of airway inflammation in mice asthmatic model and reduce the IgE serum level.

Objective To evaluate the therapeutic effect of acupoint catgut embedding on gastrointestinal dysfunction after surgery in patients with severe traumatic brain injury.Methods Sixty-eight consecutively hospitalized patients with gastrointestinal dysfunction after surgery in patients with severe traumatic brain injury admitted to the Department of Intensive Care Unit (ICU) in the First Affiliated Hospital of Zhejiang University of Chinese Medicine from January 2015 to December 2015 were enrolled.Six of those patients were withdrawn from the course of observation,and actually only 62 patients entered the study.They were divided into an observation group (32 cases) and a control group (30 cases) by random number table.All the patients of two groups were given conventional treatment of western medicine for consecutive 7 days.The observation group was additionally treated with acupoint catgut embedding.The control group took mosapride tablets via a nasogastric tube 5 mg,3 times a day.Intra-abdominal pressure (IAP),gastric residual volume (GRV),time for reaching standard enteral nutrition,serum diamine oxidase(DAO),D-Lactate activity,incidence of hospital-acquired pneumonia (HAP),hospitalization days in ICU,28-day mortality and adverse reactions of acupoint catgut embedding were observed in the two groups.Results After treatment,the levels of IAP,DAO,D-lactic acid were lower than those before treatment,GRV was less than that before treatment in the two groups,and after treatment for 7 days the changes were more significant in the observation group [IAP (cmH2O,1 cmH2O =0.098 kPa):12.42±3.11 vs.17.70 ± 2.98,GRV (mL):129.54 ± 57.54 vs.242.91 ± 99.29,DAO (U/L):9.06± 2.84 vs.13.60 ± 7.16,D-Lactate (mg/L):16.47 ± 5.39 vs.26.29 ± 9.62,all P ＜ 0.01].Days of mechanical ventilation (days:6.97 ± 4.13 vs.9.23 ± 4.61),time for reaching standard enteral nutrition (days:4.25 ± 3.15 vs.5.50 ± 3.12) and hospitalization days in ICU (days:9.50± 4.03 vs.12.20 ± 6.38) in observation group were significantly shorter than those in control group (all P ＜ 0.05).The incidence of HAP [15.6％ (5/32) vs.40.0％ (12/30)] and 28-day mortality [3.1％ (1/32) vs.6.7％ (2/30)] in observation group were obviously lower than those in control group.The patients in observation group had no significant adverse reactions of acupoint catgut embedding.Conclusions Acupoint catgut embedding therapy is not only easy to operate,but also can effectively improve gastrointestinal motility and intestinal barrier function in patients with gastrointestinal dysfunction after surgery of severe head injury,thus it is beneficial to reaching the enteral nutritional goal in less time,reducing the incidence of HAP,shortening the hospitalization time in ICU and promoting the recovery of the patients.

Objective To investigate the macrophages (Mφ) phenotype mechanism in acute kidney injury caused by severe acute pancreatitis (SAP).Methods Sixty-four male Wistar rats were randomly divided into control group (SO) and SAP group (n =32 in each group).SAP rat model was made by retrograde cholangiopancreatic injection of 5％ sodium taurocholate.At 2,6,12 and 24 h after modeling,the samples of blood and kidney tissue were collected.The levels of blood urea nitrogen (BUN) and creatinine (Cr) were detected by using automatic biochemical analyzer.The expressions of IL-12,TNF-α,IL-10 and TGF-β mRNA of kidney tissue were detected by fluorescence quantitative polymerase chain reaction (QRT-PCR).The levels of CD68,iNOS and Arg-1 were measured by Western blot.Results In the SAP group at each interval,BUN and Cr concentrations were significantly higher than those of the control group (P ＜ 0.01,P ＜ 0.05) ; Compared with the control group,the expressions of IL-12,TNF-α,IL-10 and TGF-β mRNA in renal tissue of SAP group were significantly higher (P ＜ 0.01,P ＜ 0.05).In the SAP group,the levels of CD68,iNOS and Arg-1 were higher than those in the control group.Conclusions Inflammation and inflammatory imbalances may be pathological factors of acute kidney injury following SAP.

Objective To study the changes of interleukin-4(IL-4),IL-6,IL-8 in children with idiopathic thrombocytopenic purpura(ITP).Methods The serum of IL-4,IL-6,IL-8 in 35 ITP patients and 20 normal control children were detected by enzyme-linked immunosorbent assay.Results The serum IL-4,IL-6,IL-8 in ITP patients were elevated. There were significant difference between ITP group and control group(P

Objective To investigate the expressions of transferrin receptor (TfR) mRNA, ferritin(Fn) mRNA and iron regulatory proteinl (IRP-1) mRNA in the placentas complicated with fetal iron deficiency(ID). Methods Depending on the cord SF,the subjects were divided to fetal ID group and fetal iron sufficient( IS) group. TfR mRNA, Fn mRNA and IRP - 1 mRNA in placentas were measured by RT - PCR. Results 1. The expression of TfR mRNA in ID group was 1.10 ? 0. 26, it was significantly higher than that in IS group (t=0.028 P0.05) ;4. TfR mRNA and Fn mRNA correlated with fetal IS respectively. Conclusion Fetal ID induces highly expressed TfR mRNA and lower level of Fn mRNA to furthest satisfy the iron need for fetus.
