One hundred and forty mice, weighing 30-35 grams, were divided into irradiation group (12 Gy total body irradiation from a 60Co source), combined radiation-burn group (12 Gy total body irradiation and 15% TBSA third degree burns), and normal control group.The dynamic changes of the intestinal epithelium were observed with light and electron microscopes and autoradiography within 96 hours after injuries, and attention was paid to the formation and conversion of the misshapen cells. It was Jound that the proliferative cycle of the young cells in the intestinal crypts which were severely injuried by irradiation was significantly retarded, and their G1-phase to G2-phase were prolonged. These cells gradually changed into misshapen cells. Some of the misshapen cells could not divide and finally they wer.e desquamated; abortive proliferation was found in some of them; some others showed pathological karyokinesis. Thus polymorphic cells were formed. It was difficult to show that the misshapen cells could take part in the repair of the intestinal epithelium. It is speculated that the misshapen cells might to some extent have the function of absorption, secretion and barrier.

Objective To investigate the effect of Mannatide capsules and Thymic peptide on children with recurrent respiratory tract infections(RRI) and the influnence on their immunity. Methods 160 patients with recurrent respiratory tract infections were randomly divided into the control group and the treatment group,the treatment group were treated with Mannatide capsales and Thymic peptide while the control group with only the routine therapy. Results The effect of the treatment group was over the control one(P＜0.01),two groups of the patients were promoted on Ig level,and the effect of 160 cases in the treatment group was more obvious than that of the control one(P＜0.05). Conclusion Mannatide and Thyrnic peptide applied together are effective in treating children with recurrent respiratory tract infections.

Objective To investigate the expression of S-phase kinase associated protein 2 (Skp2) in rats with acute liver failure (ALF) and its significance. Methods There were 256 male SD rats used in this study, among which 240 were injected with D-galactosamine (D-GaIN) to set up ALF model. The rats were divided into 3 groups: ALF model group, free hepatocellular transplantation group, microencapsulated hepatocyte transplantation group, which were intraperitoneally injected with 2 mL of RPMI 1640 culture medium, free hepatocellular suspension and microencapsulated hepatocyte suspension, respectively. The other 6 rats were in control group and the rest 10 rats were used for hepatocyte isolation. Expressions of Skp2 protein in hepatocytes of rats at different time points were detected by immunohistochemical technique. Levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST) and total bilirubin (TBil) were detected by automatic biochemistry analyzer. The survival rate in each group was observed. Comparisons among groups were done using one-factor analysis of variance. Results Levels of ALT, AST and TBil decreased more significantly by intraperitoneal transplantation of microencapsulated hepatocytes than those by intraperitoneal transplantation of free hepatocytes (P<0. 05). Skp2 labeling indices after 36 h of injection in ALF model group, free hepatocellular transplantation group and microencapsulated hepatocyte transolantation grouo were (28. 2±6.1) %, (41.4± 10. 5) % and (68. 0±10.8) %, respectively (F=29. 08 , P<0. 05). There were 4, 6 and 11 out of 15 rats survived in the 3 groups, respectively. Conclusion The dynamic observation of Skp2 expression could be used to judge the regeneration of hepatocytes.

Objective To study curative efficacy of cyclophosphamide combined with VAD regimen in treatment of multiple myeloma and its effects on coagulation function.Methods 78 patients of multiple myeloma who received therapy from July 2013 to July 2016 in our hospital were selected as research objects, and divided into the control group and the observation group , the control group was treated with VAD regimen, while the observation group was treated with cyclophosphamide combined with VAD regimen.Then coagulation factor and anti-coagulation factor activity, adverse reaction, therapeutic effect after treatment between two groups were compared.Results After treatment, decreased blood coagulation factor, Protein C, protein S and antithrombin were increased between two groups , the difference was not statistically significant.Incidence of adverse reactions in observation group was less than the control group[15.38%(6/39)vs 46.15%(18/39)], the difference was statistically significant(P<0.05);The total effective rate of observation group was statistically higher than that in the control group [ 89.74%( 35/39 ) vs 58.97%( 23/39 ) ] , the difference was statistically significant(P<0.05).Conclusion Cyclophosphamide combined with VAD regimen is well for multiple myeloma, which can effectively improve the patient's condition, improve the life quality of patients, and will not cause a greater impact on blood coagulation function.

Objective To explore the effects and relationship of tert-butyl hydroperoxide (t-BHP) and hypoxia in transient ischemia-like attack (TIA-like) in Kunming mice.Methods Fifty-six mice were randomly divided into normal saline group (group A), t-BHP group (group B), t-BHP plus hypoxia group (group C) and model group (group D). Fourteen mice in group D were injected t-BHP (0.11 mol/L, 10 ml/kg) through tail vein with an interval of 24 hrs to induce TIA-like attack. The average time of TIA-like was ( 3.7? 1.1) days, and this time was used as experimental evidence to collect blood sample in other groups. Hemorheological indexes before TIA-like attack were observed in different experimental conditions.Results Compared with group A, the whole blood viscosity at shear rate 100S-1, 1S-1 and Fibrinogen were significantly increased in group B and group C (all P

Objective To analyze the relationship between hepatitis B virus gene mutation at site 1896 in precore region and genotypes as well as liver function parameters. Methods The fluorescent quantitative PCR and sequencing method were applied to measuring the relevant indicators in 50 patients with chronic hepatitis B. Results There was significant difference in ALT level between hepatitis B patients with site 1896 mutation and ones with wild-type; and HBV mutation at site 1896 in precore region was unrelated to the genotypes. Conclusion HBV mutation at site 1896 in precore region may be associated with continous viral invasion invasion into hepatocytes.

Objective To investigate Bcl-2 expression in the peripheral blood mononuclear cells and its clinical significance of liver fibrosis (LF). Methods Tested Bcl-2 protein levels in T, B cells of 47 patients (male 17, female 30) with LF, 35 patients (male 24, female 11) with chronic hepatitis B and no LF and 41 cases (male 29, female 12) normal controls by two color cytofluorography. Results Among them, LF patients, chronic hepatitis B without LF and normal controls, the proposition of T cells (including CD3~+, CD4~+ and CD8~+ subgroups) and CD19~+ B cells expressed Bcl-2 protein increased significantly in LF patients (P

Objective To analyze the etiology and the clinical characteristis of fever in older patients in Wenzhou.Methods Totolly 87 cases admitted to the First Affiliated Hospital of Wenzhou Medical College from January 2001 to April 2004 were retrospectively analyzed;all cases displayed fever as the major clinical manifestation and met the criteria of fever well.Results The etiology of fever which was infectious disease was in 44 of the 87 cases,accounting for 50.6%,collagen-vascular diseases 4.6%,neoplasms 10.3% and miscellaneous diseases 5.7%.In 28.7% of the cases the etiology could not be found.And in the infectious disease the tuberculosis accounted for 13.6%(6/44). Ultrasonography ,X-rays,CT scan,MRI,the marrow puncture and biopsy contributed to the final diagnosis in 21.1%,16.9%,63%,0,16.7% and 57.1% of the cases,respectively.Conclusion Because the symptoms of the older patients'febrile diseases are atypical,the diagnosis is more difficult.Infectious disease still remains a major cause of the fever in the elderly.A thorough history of disease,full physical examination of the patient and routine laboratory studies,especially erythrocyte sedimentation rate,are very important in determining the etiology of febrile disease.Early and reasonable use of non-invasive imaging techniques and the essential invasive methods are helpful to diagnosis.

Objective To evaluate the effectiveness of PGE1 therapy for survival and incidence of complications in patients with liver failure.Methods MEDLINE,EMBASE.com,Cochrane Controlled Register and CBMdisc were searched.Randomized controlled trials of PGE1 therapy for liver failure were collected and reviewed.The quality of articles was evaluated and data was extracted from it.The odds ratio for death and complications among the patients with PGE1 therapy as well as the blank controls was calculated at the end of therapy.The results of meta-analysis were assessed according to sensitivity and bias.RevMan4.2 was applied to process the data.Results The results of meta-analysis showed that PGE1 reduced the case-fatality ratio of liver failure [OR=0.30,95%CI(0.23～0.37)] and the risk difference was decreased 29% in PGE1 patients compared with the blank controls.And there was statistical significance in PGE1 reducing the incidence of hepatorenal syndrome,but occurance of the complieations such as hepatic encephalopathy,bleeding,infection etc.These results were not reversed in the analysis of sensitivity,and the analysis of bias showed little bias of them.Conclusions PGE1 can reduce the case-fatality ratio of liver failure and the incidence of hepatorenal syndrome.The accuracy of the results are low due to the poor quality of the included trials.Thus, the effect of PGE1 on liver failure needs to be further evaluated through randomized controlled trials of high quality to be carried out in multicenter and large samples.
