China Pharmacy 1991;0(03):-
OBJECTIVE:To investigate the antiviral action of emodin in combination with other Chinese active medicine components on Coxsackie virus B3(CVB3) and explore the possible antiviral mechanism.METHODS:Hep-2 cells infected by CVB3 were cultured with different concentration and proportion of the emodin and other Chinese medicine components for 72 hours and their inhibitory effects on CVB3 replication were evaluated with cell survival rates by MTT assay.RESULTS:In the Hep-2 cell system,all the combinations between emodin and other medicine components could inhibit cytopathic effect(CPE) of CVB3-infected cells,increase cells' survival rates and decrease the cytotoxicity.The drug combination which showed the best effect of killing viruses directly was emodin:curcumine:banlangen(2:1:2),and the one showing the highest efficacy in inhibiting the replication of CVB3 in cells was emodin:curcumine:banlangen(2:0:1).CONCLUSION:The toxicity of emodin was reduced and its anti-CVB3 activity was enhanced by its combined use with other Chinese active medicine components.
3.Effect of recombinant human interleukin-1 receptor antagonist on metabotropic glutamate receptor 5 of the hippocampus following global cerebral ischemia reperfusion
Chinese Journal of Tissue Engineering Research 2005;9(40):158-161
BACKGROUND: Interleukin-1 receptor antagonist can relieve damage of neuron and protect nerve. Aminoglutaric acid can induce exitotoxicity through activating some kinds of aminoglutaric acid receptor, at the same time, can protect nerve through some receptors. But the relationship between them was unclear during the process of cerebral ischemia reperfusion.OBJECTIVE: To investigate the effect of neuroprotective actions of interleukin-1 receptor antagonist on hippocampal neurons, and the relationship between interleukin-1 receptor antagonist and metabotropic glutamate receptor 5 within the process of cerebral ischemic reperfusion injury.DESIGN: Completed randomized controlled study.SETTING: State Key Laboratory of Magnetic Resonance and Atomic and Molecular Physics, Wuhan Institute of Physics and Mathematics, Chinese Academy of Sciences; School of Medicine & Life, Jianghan University.MATERIALS: The experiment was performed at State Key Laboratory of Magnetic Resonance and Atomic and Molecular Physics, Wuhan Institute of Physics and Mathematics, Chinese Academy of Science from May 2004 to January 2005. Totally 32 well-being pure breed male Wistar rats were selected.METHODS: Totally 32 rats were divided into four groups by method of the simple random sampling: normal group (n=8) received no surgical treatment, sham operated group (n=8) subjected to only dorsal and ventral neck midline incisions and gently dissection of the bilateral common carotid arteries free of surrounding nerve fibers without occlusion of the both vertebral arteries and common carotid arteries, saline group (n=8) suffered from the permanently occlusion of the both vertebral arteries by electrocauterization and transient (20 minutes) occlusion of bilateral common carotid arteries respectively, and received the treatment of a 2 μL normal saline injection into right lateral ventricle at the rate of 0.4 μL/minute following a needle withdrawal within 5 minutes, and experiment group (n=8) offered the same procedure of the saline group but for that the equivalent amount of rhIL-1ra took the place of normal saline into the lateral ventricle. Hematein-eosin staining was applied to observe pathological changes and immunohistochemistry (ABC) was used to survey the IR of mGluR5 varieties of the hippocampal neurons.MAIN OUTCOME MEASURES: ① Basic pathological changes of hip pocampus and cerebral cortex; ② mGluR5 immunoreactivity (IR) of hippocampus, the sensitive area to cerebral ischemia.RESULTS: Two rats were excluded from the experiment on account of their convulsion during reperfusion (one of the experiment group, another of the saline group), data of 30 rats was entered final analysis. ①Basic pathological changes of hippocampus and cerebral cortex: The Hemateineosin (H.E) staining showed that there is little pathological discrepancy between the normal group and the sham operated group, apparent neuronal degeneration such as peripheral edema around neurons, pyknosis, karyorrhexis and so onin the hippocampus and cortex of the rats of the saline group compared with those of the previous groups, and also the pronounced lower degree of neuronal degenerationin the rats of the experiment group.② mGluR5 immunoreactivity (IR) of hippocampus, the sensitive area to cerebral ischemia (absorbency): The immunohistochemistry presented that the mGluR5 immunoreactivity (IR) of CA1, CA3 areas of the normal group and sham group rats was strong positive (CA1: 0.54±0.12, 0.54±0.05; CA3:0.57±0.02, 0.58±0.08;P > 0.05) Compared with of the normal group and sham group, the mGluR5 IR of the saline and the experiment groups reduced apparently (CA1: 0.30±0.03, 0.40±0.04; CA3: 0.30±0.04, 0.42±0.06;P < 0.01), but the mGluR5 IR of the experiment group was quite stronger than that of the saline one (P < 0.05).CONCLUSION: IL-1ra, one member of the Interleukin-1 family (system)of the cytokines, and mGluR5, one subtype of the metabotropic glutamate receptors were both involved in the pathophysiological process of the global cerebral ischemia reperfusion injury of the rat. Also, as the antagonist of the proimflammatory medium intetleukin-1 receptor, IL-1ra may show neuroprotection by affecting the mGluR5 expression of the CA1 and CA3 areas of the rat hippocampus within the process of cerebral ischemic reperfusion injury. Furthermore, here it demonstrated that besides IL-1ra, other factors might regulate the expression of mGluR5.
4. Spindle cell lesions in breast diseases
Academic Journal of Second Military Medical University 2011;32(11):1249-1254
Breast tumors are the most common tumors of epithelial origin. Some tumors or tumor-like lesions of the breast may display a morphology similar to mesenchymal tumors predominated by spindle cells. However, such morphology is apt to be confused with others due to lack of the characteristic histopathology. This paper reviews some spindle cell lions in the breast, in an attempt to provide theoretical evidences for the differentiation diagnosis of breast tumors and tumor-like lions.

Objective To investigate the clinicial significance of continuous glucose monitoring(CGM)of patients with severe traumatic brain injury(sTBI). Methods By glucose monitoring method,80 patients with sTBI〔Glasgow coma score(GCS)3-8〕in Department of Critical Care Medicine of Qingyuan People's Hospital in Guangdong Province from January 2012 to December 2012 were divided into two groups:41 patients in CGM group and 39 in regular glucose monitoring(RGM)group. The continuous glucose monitoring system(CGMS)was applied to monitor glucose level in the CGM group,and the finger blood was taken by portable blood glucose meter in the RGM group. The two groups were treated with insulin on the basis of glucose level,respectively. The relationships between the condition of glycemic excursions and the acute physiology and chronic health evaluationⅡ(APACHEⅡ)score or prognosis and between the incidence of hypoglycemia and prognosis were seen in the two groups. Results The close linear correlations between APACHEⅡ score and glycemic excursion in two groups,i.e. mean amplitude of glycemic excursions(MAGE)and coefficient of variation of glucose(GluCV),were documented(both P<0.05). The MAGE of the especially severe patients(GCS 3-5)was obviously higher than that of severe ones(GCS 6-8),and with the increase of APACHEⅡ score,the MAGE of patients was gradually elevated,the difference being statistically significant(both P<0.05). The incidence of hypoglycemia(7.32%vs. 23.08%)and fatality rate of 30 days(12.20%vs. 30.77%)in CGM group were lower than those of RGM group(both P<0.05). The MAGE and fatality rate of 30 days were positively correlated in CGM group(r=0.597,P=0.007),and the GLuCV and fatality rate of 30 days were positively correlated in RGM group(r=0.622,P=0.019). Conclusion CGM is beneficial to timely observe condition of glycemic excursions in sTBI patients and avoid occurrence of hypoglycemia or hyperglycemia,guiding the treatment of insulin and improving patients' prognosis.
