Objective Research the effect of anti-inflammatory and anti-oxidation drugs on acute stroke patients. Methods 128 patients with acute ischemic stroke are divided into two groups- combined treatment group (71) and control (57). Test serum biomarkers and evaluate neurological function and living ability before and after therapy, compare between groups and intra-group. To observe the effects of combined therapy on serum biomarkers and prognosis in acute stage. Results ( 1 ) MMP-9 of combined treatment group (3.23 ±0. 99) ng/L is higher than control (2. 82 ± 4. 21 )ng/L before therapy (P ＜0. 05). (2) The level of pre-treatment ox-LDL-Ab in combined treatment group ( 0. 08 ± 0. 01 ) U/ml higher than posttreatment (0. 07 ±0. 01 ) U/ml (P ＜ 0. 05 ). The level of pre-treatment NIHSS in control group (5.76 ±6.61) score higher than post-treatment (4.22 ±5.45) score,P＜0.05. Conclusion Combined treatment can degrade serum MMP-9 and ox-LDL in acute ischemic stroke patients, but it can't obviously improve the earlier prognosis.

Objective To assess the incidence, types and risk factors of atherothrombotic events (AT) within 7 days after transient ischemic attack (TIA) with ABCD2 Score in Chinese patients. Methods With ABCD2 Score, we retrospectively reviewed the medical records of 198 TIA patients ,which met the inclusion criteria of our study. They were divided into a low risk group (ABCD2 ≤3) and a moderate-high risk group(ABCD2≥4) and the incidence, types and risk factors of AT within 7 days after TIA were evaluated and compared respectively with χ2 test between the two groups. Statistic significance was considered as P < 0.05. Results The order of the frequency of accompanying diseases was hypertension 68.18% (135/198), diabetes 23.74% (47/198), coronary artery disease 21.72% (43/198), ischemic stroke 15.66% (31/198) and hyperlipemia 12. 63% (25/198). AT within 7 days after TIA was observed in 6.19% (6/97) of the patients in the low risk group, all of them were suffering from TIA recurrence. In the moderate-high risk group, 14. 85% (15/101) of the patients experienced AT, including 2 eases of TIA recurrence, 10 cases of ischemic stroke, 1 case of both TIA recurrence and ischemic stroke, 1 case of angina pectoris and 1 case of myocardial infarction. There was no peripheral vascular disease or death from vascular disease. Incidence of AT within 7 days in the moderate-high risk group was significantly higher than that in the low risk group (51.70% vs 27. 27%, P < 0.05). Conclusion TIA patients with ABCD2 ≥4 are at higher risk of AT within 7 days after TIA onset.

PURPOSE: To investigate the neuroprotective effect of growth hormone(GH) on neuronal cell necrosis and apoptosis at 1 week and 3 weeks after hypoxic ischemic brain injury. METHODS: Sprague-Dawley rats, seven-day-old, were used. Rats were anesthetized with ether less than 5 minutes. The right carotid artery was cut between double ligation. And then, rats were allowed to recover for 30 minutes followed by exposure to 8% oxygen at 37 degrees C for 2 hours for hypoxic ischemic insult. The study group was divided into 2 groups, control group(N=3) and GH treated group(N=3). GH treated group received intraperitoneal injection of GH 1 IU 2 hours after hypoxic ischemic insult following daily adminstration as same dose for 5 days. Rats were decapitated at 1 week and 3 weeks after hypoxic ischemic brain injury. After then, right hippocampal CA1 and CA3 neurons of rat brains were examined. RESULTS: Necrosis was significantly less in GH treated group than control group, and was more prominent at 3 weeks in both groups. The apoptosis was not found in GH treated and control group. CONCLUSION: GH has a neuroprotective effect on neuronal cell deaths(especially necrosis) from 1 week to 3 week after hypoxic ischemic insult in neonatal rat.

Objective Endogenous cadiac stem cells become the famous star in the cardiac regeneration field in recent years.But the biological behavior of cardiac stem cells has not been fully explained clearly.This experiment intends to research the cardiac stem cell niche and its characteristics,as well as the succinct method for cardiac stem cells (Cardiospheres derived cells) culture in vitro.Methods Hearts from four 8-week-old SD rats were cut into pieces less than I mm3.Then,the small tissues were digested by trypsogen and collagenase in turn.And the undigested myocardium was collected and cultured in media until the de novo cells bespread the pertri-dish bottom.The 3rd generation of cardiac stem cells were harvested and prepared for immunofluorescence to detect the expression of related molecular markers,so as to identify the differentiation of these stem cells.Then,the cultural tissues were collected and embedded in paraffin,and the H-E staining,Masson staining,immunoflnorescence and TUNEL apoptosis assay were carried out.In addition,EdU was added into the medium and cuhured for 72 hours before the cultural tissues were harvested so as to label the proliferative cells.Results After 7 ～ 10 days in culture,some small,round and phase-bright cells aresed from the adherent plated tissue.These cells had the spontaneous differentiation potency in vitro culture.The immunofluorescence shows mitotic phase cells were c-kit positive,and most of passage cells were α-sarcomeric actin 、cardiac troponin T、flk-1 and vemintin positive while CD90 negative,but few of them were α-smooth muscle actin 、conexin-43 、CD31 and CD45 positive.There were lots of newborn cells grow exuberantly while accompanied apoptosis of myocardial cells in the paraffin section.The myocardial collagen remodels in the cultural myocardial tissues at the same time.The proliferative cells in the cultural tissues were EdU positive.Throe myocardium within the cultural tissues were MMP-2、MMP-9 and TGF-β1 positive,On the contrary,the proliferative cells were almost negative when stained with those antibodies.Conclusion Conclusions It's a convenient way to harvest cardiac stem cells by the use of myocarlial? tissues cultured in vitro.Those stem cells grow and proliferate in the cultural myocardial tissues accompanied with the degradation of extracellular matrix.Cardiospheres derived stem cells have the spontaneous differentiation potency when cultured in vito,and should be a promising? seed cells for stem cell therapy.

Objective To investigate the safety and efficacy of structured triglycerides in parenteral nutrition in elderly patients with acute biliary tract infection.Methods 62 elderly patients with acute biliary tract infection under conservative therapy were randomly divided into structured triglycerides (ST) group and medium-chain triglycerides plus long-chain triglycerides (MCT/LCT) group.Patients underwent parenteral nutrition for 5 days.Levels of hepatic enzymes,blood triglycerides,nitrogen balance,fasting blood insulin and glucose were compared between the two groups after 5 days of parenteral nutrition.Results There were no significant differences in levels of hepatic enzymes,blood triglycerides and fasting blood glucose between ST group and MCT/LCT group.Plasma total bilirubin (T-Bill) levels were increased in the two groups,and T-Bill level dropped faster in the ST group than in the MCT/LCT group after 7 days of parenteral nutrition(P＜ 0.05).The difference in total cholesterol level dropping was significant between ST group and MCT/ LCT group (P＜0.05).The cumulative nitrogen balance for 5 days had significant difference between ST and MCT/LCT groups [(4.7-±-2.2) g vs.(2.8±0.7) g,P＜0.05].STG group versus MCT/LCT group had less fluctuation of fasting blood insulin level after 1,4 and 7 days of parenteral nutrition.Conclusions In the acute phase of biliary tract infection in elderly patients,ST-based parenteral nutrition can provide energy and help maintain nitrogen balance,with a little fluctuation of fasting blood insulin level.Short-term nutritional support may have better tolerance in the liver and has little effect on the change of hepatic enzymes.
