Objective To study the morphological changes in peripheral blood cells and bone marrow cells of the patients suffering from mustard gas poisoning and their relationship with the degree of poisoning. Method The peripheral blood cells and marrow cells were examined morphologically after mustard gas poisoning. Results The total WBC count was reduced progressively in 44 patients, among them 10 patients showed granulocytopenia or agranulocytosis. Severe injury to eosinophils was seen also in the early period, and the percentage and absolute value of lymphocytes were significantly lowered too. However, platelets were not significantly influenced. The red cell count and hemoglobin level were elevated because of hemoconcentration. Blood marrow cells showed marked morphological changes. WBC became swollen with appearance of poisonous granules and vacuoles in their cytoplasm. Deformed lymphocytes (LY) could be found in the marrow cells of all the patients, mainly in the form of immature lymphocytes. It was shown that mustard gas produced serious damage to the hematopoitic cells of the bone marrow in the early period. Conclusions The examination of pheripheral blood and bone marrow cells is an important measure to determine the degree of mustard gas poisoning. The decrease in the absolute value of lymophocyte count and the time of its recovery, and degree of inhibition of hematopoiesis are closely related to the degree of mustard gas poisoning.

AIM: To investigate the key molecular mechanism of inflammatory response in alveolar epithelial cells induced by nontypeable haemophilus influenzae(NTHi).METHODS: A549 cells were co-cultured with NTHi(multiplicity of infection,MOI: 10) and harvested 15 min and 30 min after stimulation.The phosphorylation of p38 mitogen activated protein kinase(p38 MAPK) in A549 cells was detected by Western blotting.The intracellular expression of nuclear factor-?B(NF-?B) p65 was examined by flow cytometry 4 h after stimulation.A549 cells were preincubated with p38 inhibitor(SB203580) or NF-?B inhibitor(PDTC) for 1 h and then stimulated with NTHi for 24 h.The level of interleukin 8(IL-8) in the supernatants was determined by enzyme-linked immunosorbent assay(ELISA).RESULTS: The phosphorylation of p38 MAPK was rapidly induced by NTHi stimulation.The expression of NF-?B p65 in A549 cells after NTHi stimulation was significantly up-regulated compared with control group(P

OBJECTIVE: To investigate the effects of resveratrol on the expression of SIRT1,the activity of eNOS and the secretion of NO of highlipid cultured primary human umbilical vein endothelial cells(HUVEC).METHODS: HUVEC were divided into normal control group,highlipid group and highlipid+resveratrol group,cultured for 24 hours.The expression of SIRT1 mRNA and protein were analyzed by RT-PCR and Western blot methods.Supernatant were used to analyze the nitric oxide(NO) content and activity of endothelial nitric oxide synthase(eNOS).RESULTS: Compared with highlipid group,resveratrol group increased the expression of SIRT1 mRNA and protein,the activity of eNOS and the secretion of NO(P

BACKGROUND:Neural stem cells (NSCs) hold self-renewal and multi-directional differentiation potential. NSCs differentiation into neurons in high proportion under induction conditions exhibits broad application prospect. OBJECTIVE:To explore the effect of basic fibroblast growth factor (bFGF)-chitosan carrier on the NSCs differentiation into neurons in vitro, and whether the differentiated neurons could form synaptic-like connection with myocytes. METHODS:After purification, the NSCs were co-cultured with chitosan, soluble bFGF or bFGF-chitosan carrier. After 7-day induction, the NSCs differentiation into neurons was observed by immunofluorescence staining of beta tubulin Ⅲ. The NSCs differentiation into cholinergic neurons was observed through double immunofluorescence staining of ChaT and beta tubulin Ⅲ. The synaptic-like connection between the neurons and myocytes was observed by triple staining of beta tubulin Ⅲ and MHC. RESULTS AND CONCLUSION:The percentage of differentiated neurons in the bFGF-chitosan carrier group was 74%, which was significantly higher than that in the other two groups. Additionally, the synaptic-like connection formed between the differentiated neurons and myocytes. To conclude, the bFGF-chitosan carrier promotes the NSCs differentiation into neurons to form synaptic-like connection with the co-cultured myocytes.

Purpose To exp1ore the expression and c1inica1 significance of epiderma1 growth factor receptor( EGFR)and human epi-derma1 receptor-2(HER-2)in co1orecta1 carcinoma. Methods Immunohistochemistry(IHC)PV-9000 was used to detect the expres-sion of EGFR and HER-2 in 78 cases of co1orecta1 carcinoma. Si1ver in situ hybridization( SISH)was used to detect HER-2 amp1ifica-tion in co1orecta1 carcinoma. Results The positive rates of EGFR in 78 co1orecta1 carcinomas were 69. 23%( 54/78 ). The differ-ences of the expression of EGFR between different depth of invasion group and 1ymph node metastasis group were statistica11y signifi-cant. The differences of the expression of EGFR between different aging group,gender group,tumor size,different histo1ogica1 grading group and Dukes stage were insignificant. The positive rates of HER-2 in 78 cases of co1orecta1 carcinoma were 25. 64%(20/78). The differences of the expression of HER-2 between different depth of invasion group and 1ymph node metastasis group were statistica11y sig-nificant. The differences of the expression of HER-2 between different aging group,gender group,tumor size,histo1ogica1 grading group and Dukes stage were insignificant. The expression of EGFR and HER-2 was positive1y corre1ated. Among the 20 cases of HER-2 protein overexpression,10 cases showed HER-2 gene amp1ification,15 cases showed HER-2 protein overexpression(~)by IHC and 10 cases showed HER-2 gene amp1ification by SISH. The rate of HER-2 gene amp1ification was 66. 67%. 5 cases with 1ow HER-2 protein overexpression( +)and no case showed HER-2 gene amp1ification. Conclusions EGFR and HER-2 are high1y ex-pressed in co1orecta1 carcinoma. EGFR and HER-2 expression is connected to invasion and metastasis process of co1orecta1 carcinoma. The both may be synergy. The corre1ation between HER-2 protein overexpression(~)and HER-2 gene amp1ification is statisti-ca11y significant. Therefore,immunohistochemistry can be regarded as an initia1 screening method for HER-2 gene amp1ification,and then SISH testing shou1d be done as we11 to confirm the resu1t. It is usefu1 for mo1ecu1ar target therapy to detect HER-2 status in co1or-ecta1 carcinoma.
