Objective To study the relationship of microinflammation,nutrition and common carotid artery intima-media thickness(CCA-IMT) for the early prevention and interference of ischemic stroke. Methods(CCA-IMT was) measured by carotid arterial ultrasound in 250 elderly subjects.The levels of serum high-sensitivity C-(reactive) protein(hsCRP),ferritin,albumin,pre-albumin and transferrin were assayed at the same time.According to the results of CCA-IMT,all the subjects were divided into five groups:

Objective To induce cord blood derived endothelial progenitor cells(EPCs)into endothelial cells,and investigate the feasibility of these cells as the seed cells of tissue engineering cardiovascular replacement.Methods Mononuclear cells were isolated from fresh cord blood by 6%HES and density gradient centrifugation.Isolated cells were cultured in medium supplemented with vascular endothelial growth factor(VEGF).Attached cells were identied by morphology,immunofluorescence staining and flow cytometry.Results The percentage of mononuclear cells isolated from fresh cord blood was(3.4?2.1)?10~7/mL.The morphology of attached cells changed while being cultured and inducted,from small-sized round cells to spindle-like cells,to a typical cobblestone morphology,and the total number of cells was 10~7.After 7 days of culture,immunofluorescence staining showed that the vWF and VEGFR-2 were expressed.Compared with the original,cell markers CD_133 decreased(3.11%?1.05%) to(0.09%?0.02%),P

OBJECTIVE: To study the deduction of injury-causing instruments and its value as judicial evidence. METHODS: To collect 146 cases involved in injury-causing instruments deduction, which accepted by Judicial Appraisal Center of Wannan Medical College during the period from 1998 to 2007, then to deduce the instrument by analyzing the characters of injuries in body surface. The accuracy of those deductions was evaluated by comparing the deduced instruments with the actual instruments. RESULTS: The deduction from sharp injuries was more accurate than that from blunt injuries. CONCLUSION Sometimes the result of deduction about injury-causing instruments are uncertain, it may be accepted as judicial evidence when supported by other evidences.

OBJECTIVETo evaluate the therapeutic effect of Liujunzi decoction combined with Zuojin pills in treating the radioactive duodenitis and their mechanism, and compare with clinical routine acid suppressants combined with mucous membrane protective preparations to study the mechanism of their efficacy.

METHODAccording to the study of Williams J P and characteristics of duodenitis, and by reference to the radiation enteritis modeling standard, we took the lead in establishing the mouse radioactive duodenal injury model. The model mice were randomly divided into the control group (n = 26), traditional Chinese medicine (TCM) group (n = 16) and the western medicine (oral administration with famotidine 0.5 mL + almagate suspension 0.3 mL per mouse, once a day) group (n = 16). After the standard administrating, such objective indexes as general condition, weight, changes in health score, pathology and expression of inflammatory factors were observed to evaluate the efficacy.

RESULTThe radioactive duodenitis model of mice was successfully established with 12 Gy. Mice in the control group suffered from weight loss, anorexia, low fluid intake, loose stools, and occasionally mucous bloody stool, poor spirit, dim fur, lack of exercise and arch back. Mice in drug intervention groups were generally better than those in the pure irradiation group. The IL-6, IL-1beta, TNF-alpha mRNA expressions in spleen and mesenteric lymph node tissues in TCM and western medicine groups showed a declining trend compared with the control group. Their concentrations in peripheral blood serum also slightly changed. The TCM group revealed notable advantage in reducing inflammatory factors. The microscopic observation showed that a better mucosa repair in intervention groups than the pure irradiation group. The improved Chiu's scoring method showed a statistical significance in the difference between TCM and western medicine groups (P < 0.05).

CONCLUSIONLiujunzi decoction combined with Zuojin pills could treat acute radiation enteritis, regulate organic immunity, and inhibit acute injury, promote local tissue repair, with the potential to resist such adverse effects as radiation intestinal fibrosis. The regulation of inflammatory factor release is one of efficacy generation mechanisms.

This study is to investigate the impairment and possible mechanism of endothelium-dependent relaxation of mice mesenteric arteries induced by mmLDL. Wire myography was employed to examine endothelial function of mesenteric arteries. Ultramicrostructure of mesenteric vascular beds were detected by transmission electron microscope. The results showed that endothelium cell edema and peeling, vascular elastic membrane fracture traces in mmLDL group. Endothelium-dependent relaxation was decreased in a time-dependent and dose-dependent manner by using mmLDL, compared with normal arteries. In endothelium-derived hyperpolarizing factor (EDHF)-mediated relaxation, the Rmax and pIC50 were decreased from (63 +/- 5) % and 6.42 +/- 0.09 of normal saline control to (31 +/- 3) % and 5.67 +/- 0.07 in mmLDL group (P < 0.001, P < 0.001), respectively. In nitric oxide (NO)-mediated relaxation, the Rmax and pIC50 were decreased from (45 +/- 4) % and 5.93 +/- 0.08 in normal saline control to (32 +/- 4) % and 5.43 +/- 0.11 in mmLDL group (P < 0.05, P < 0.01), respectively. There is no significant alteration of prostacyclin I2 (PGI2) pathway between these two groups. In conclusion, mmLDL induced the impairment of the ultramicrostructure of mesenteric vascular endothelium cell as well as the endothelium-dependent relaxation. The latter includes the dysfunction of NO- and EDHF pathway mediated endothelium-dependent relaxation.

Obj ectiev The purpose of this study is to assess the impact of bone metastasis on survival in non-small cell lung cancer(NSCLC),Which were treated with gefitinib for more than 6 months,and to identify the prognostic factors of patients with NSCLC presenting bone metastasis .Methods We compared the overall survival(OS), progression-free survival(PFS),1-year2,-year and 3-year survival rates between two cohorts based on bone metastasis ,as well as the prognostic factors in the patients with bone metastasis .Results In total, 76 patients were included in the study ,in which there are44 patients with no bone metastasis and32 patients with bone metastasis.The cohorts were similar in OS (19.000 ±3.317 months vs.26.000 ±2.121 months,P =0.625)as well as PFS (14.000 ±1.843 months vs.16.000 ±1.411 months,P=0.328).The 1-year survival rate was 63.6%in no bone metastasis cohort,but was increased to 96.9%in the other cohort.The survival rates at 2 years(34.1%vs.56.3%,P=0.054)and 3 years(18.2%vs.18.4%,P=0.950)were similar.The univa-riate analysis showed that a worse prognosis was more likely existed in elderly patients ( aged >60 years) and with pulmonary progression ,whereby factors including gender ,pathology s,moking index ,brain metastases ,bone related events and the application of radiotherapy ,bisphosphonates might not be independently associated with the surviv -al late.Analysis of multiple variables indicated a favorable prognosis for patients with no pulmonary progression . Conclusion This retrospective study shows that bone metastasis may not shorten the survival in patients whose pulmonary lesion was controlled by gefitinib .On the contrary ,pulmonary progression may be more likely the cause of death in patients with bone metastasis .Non suggestion is given to discontinue gefitinib when the bone metastasis appears.
