(2) Compared with conventional group, mild hypothermia group 7 d NIHSS and 24 h, 7 d ICP and ScvO2 improved significantly (P < 0.05). (3) The CVP, MAP, PT, and PLT showed no difference in two groups before and after-treatment . ( 4 ) Rate of good outcome in mild hypothermia group was significantly higher than conventional group in 90 days (P < 0.01); while the mortality rate showed no difference. Conclusions Mild hypothermia can obviously improve END in stroke with intra-arterial thrombolysise, bring better outcome among survival patients, though can not reduce mortality.

Objective To investigate the protective effects of ischemic preconditioning on myocardial ischemia/reperfusion injury in diabetic rats.Methods Twenty-eight healthy male rats were injected streptozotocin at dose of 45 mg/kg by tail and be fed with normal diet for 4 weeks,then rats were randomly divided into iscbemia/reperfusion (I/R) group and ischemic preconditioning (IP) group.ST segment of electrocardiograph changes and arrhythmias of all rats were recorded before ischemia and 0,15,30 minuets after ischemia and 0.5,2 h after reperfusion.TTC staining was performed to determine myocardial infarct size.TUNEL assay was used to assesse cardiomyocyte apoptosis.The expression of antiapoptotic gene (Bcl-2) and proapoptotic (Bax) was determined by immunohistochemistry.Results Compared with I/R group,ST segment elevation of patients in IP group decrease from (0.675 ±0.150) mV to (0.489 ±0.161) mV at 30 min after ischemia(P ＜0.05).Meanwhile the onset of ventricular premature contraction(VPC) in IP group was (18.21 ± 5.36) min,later than that of control group ((6.47 ± 4.28) min,t =5.241,P =0.000).The duration of VPC was (6.07 ± 4.33) min,shorter than that of I/R group ((16.71 ± 5.48) min,t =4.924,P ＜ 0.01)).The incidence of ventricular tachycardia (VT) and ventricular fibrillation (VF) of lP group remarkably decreased compared with I/R group (VT:57.14％ (8/14) vs.14.29％ (2/14),x2 =5.600,P =0.018 ; VF:50.00％ (7/ 14) vs.14.29％ (2/14),x2 =4.094,P=0.043).The myocardial infarct size in IP group was (12.50 ± 9.45) ％,smaller than that of I/R group ((37.50 ± 11.40)％,t =3.211,P =0.006).Cardiomyocyte apoptotic index (AI) was attenuated in IP group than that of I/R group((24.31 ± 3.12)％ vs.(19.01 ± 4.32)％,t =3.227,P =0.006),which was correlate with increased the ratio of Bcl-2/Bax((0.103 ±0.045) vs.(0.221 ±0.101),t =2.670,P =0.015).Conclusion IP treatment for diabetic rats shows a protect effect on myocardial I/R injury through attenuating myocardial apoptosis,and increasing the ratio of Bcl-2/Bax.

Objective To study the effects of mild hypothermia on cognitive function , synapsinⅠexpression and synaptic ultrastructure of hippocampus in epileptic rats induced by global cerebral ischemia. Methods Forty-eight male SD rats were randomly divided into control (NC) group, sham-operated (Sham) group, normothermic epilepsy (NT) group and mild hypothermic epilepsy (HT) group. The model of postischemic audio-genetic seizure was established by chest compression. Hypothermia intervention was given to HT group. Immunocytochemistry was conducted to detect the expressions of synapsin I in hippocampus at days 1 , 3, 14. the synaptic ultrastructure and cognitive function were respectively observed by electron microscope and Morris water maze. Results Compared with NC and Sham group, the expression of synapsinI in NT group was decreased, the escape latency was prolonged and across platform number decreased (P < 0.05). The synapses were decreased in number, and mitochondria was viewed swelling, synaptic membranes unclear, myelin fractured. Compared with NT group, the expression of synapsinⅠin HT group had no obvious change in 24 h but was significantly increased in days 3 and 14 (P < 0.01); The escape latency was decreased and the number of cross platform increased (P < 0.01); Synaptic structure was clear, with interface growing and postsynaptic density thickened. Conclusion Mild hypothermia may improve the cognitive function of the epileptic rats induced by global cerebral ischemia by upregulating the expression of synapsinⅠand alleviating the damage of synaptic structure.

BACKGROUND: Blood pressure of children increases with ages, and is related to anthropometric parameters, diet, sports, and other factors. To analyze relative factor of a little high blood pressure of children provides a scientific evidence for prevention and cure of primary hypertension. OBJECTIVE: To investigate correlation between blood pressure and anthropometric parameters among children. DESIGN: Cross-sectional study. SETTING: Department of Hygiene of Weifang Medical College. PARTICIPANTS: According to cluster sampling, 1 546 pupils in grade three or four were selected from a primary school for physical examination and questionnaires. Totally 1 508 pupils with complete data were regarded as the subjects.METHODS: Partial correlation analysis was used to analyze correlation between blood pressure and anthropometric parameters among children.MAIN OUTCOME MEASURES: Correlation among anthropometric parameters, systolic pressure and diastolic pressure.RESULTS: ① Correlation coefficients of systolic pressure with sex, age, height, body mass, chest circumference of Peason were 0.078, 0.166, 0.337, 0.313 and 0.304 (P ＜ 0.01). ② Correlation coefficients of diastolic pressure with sex, age, height, body mass, chest circumference of Peason were 0.047, 0.120, 0.268, 0.271 and 0.251 (P ＜ 0.01). ③ After controlling two effect of anthropometric parameters on each other, systolic pressure and diastolic pressure were only correlated with height and chest circumference (P ＜ 0.01), but was not correlated with age, sex and body mass (P ＞ 0.05). CONCLUSION: After controlling the effect of anthropometric parameters on each other, systolic pressure and diastolic pressure of children were positively correlated with height and chest circumference.

Background and purpose:Hypoxia induced the decreased radiosensitivity of tumor cells, which was the cause of tumor radioresistance and relapse and metastasis. During the course, HIF-1a played the most important role in the regulation of hypoxia. However, it’s still unknown about the effect of HIF-1a on the radiosensitivity of hypoxia tumor cells and the relationship with autophagy. This study was to inhibit HIF-1αexpression in hypoxic lung adenocarcinoma cell line A549 with RNA interference (RNAi), and explore its effect on hypoxic cell radiosensitivity and autophagy. Methods: Plasmids pHIF-1α-shRNA and Neg-shRNA (negative control) were constructed and transfected into hypoxic A549 cells, this positive clone was named A549/HIF-1α-shRNA. Clone formation array was applied to calculate the value of D0, SF2, SER. The expression of HIF-1α, LC3, c-parp was detected by Western blot. Results:The SF2 of hypoxic A549 cell was 0.62, which was higher than that of normoxic A549 cell, SER was 1.45. The level of LC3Ⅱincreased significantly and the level of c-parp decreased after the radiation of hypoxic A549 cell. The level of HIF-1a increased in hypoxic A549 cells. The expression of HIF-1αin hypoxic A549 cells was suppressed markedly after transfection of HIF-1α-shRNA;this clone was named A549/HIF-1α-shRNA. The SF2 and SER were significantly lower in A549/HIF-1α-shRNA cells, 0.45 and 0.72 respectively. Under the hypoxic condition and after the inhibition of HIF-1α, the expression of LC3Ⅱ decreased significantly and the expression of c-parp increased. Conclusion:We successfully established a cell model that HIF-1αexpression was suppressed almost completely by RNAi. The inhibition of HIF-1αby shRNA may raise the radiosensitivity and decrease the autophagy of hypoxic A549 cells in vitro.

Objective To investigate the correlation of serum anti-M-type phospholipase A2 receptor (PLA2R) antibody with laboratory parameters of idiopathic membranous nephropathy (IMN) in adult patients with membranous nephropathy (MN),and to explore the role of anti-PLA2R antibody in the pathogenesis of IMN. Methods Forty-six adult patients with biopsy-proved glomerular diseases were involved in this study,including 20 cases with IMN,7 cases with IgA nephropathy (IgAN),6 cases with hepatitis B-associated membranous nephropathy (HBV-MN),6 cases with minimal change nephropathy (MCN),4 cases with focal segmental glomerulosclerosis (FSGS) and 3 cases with class Ⅴ lupus nephritis.Total RNA was extracted from human glomeruli and was reversely transcribed to the first-strand cDNA.The full-length human M-type PLA2R was amplified by PCR and the 605 bp product was subcloned into eukaryotic expression vector containing CMV promoter.The recombinant human M-type PLA2R plasmid vector was transiently transfected into human embryonic kidney (HEK) 239T cell line using the FuGene6 transfection reagent.Western blotting was used to detect serum anti-PLA2R antibodies.Correlations of antiPLA2R antibody level with laboratory parameters,including serum albumin,total cholesterol,Scr and 24-hour urine protein,of IMN patients were evaluated. Results Among 20 cases with IMN,15 cases showed positive anti-PLA2R antibodies (positive rate 75％).Of 7 cases with IgAN and 6 cases with HBV-MN,only 1 case showed positive anti-PLA2R antibody respectively (positive rate 14.29％ and 16.67％ respectively).Anti-PLA2R antibody was negative in other patients.The positive rate of anti-PLA2R antibody in IMN patients was significantly higher than that in patients with secondary MN and other types of glomerlonephritis (all P＜0.01).Furthermore,anti-PLA2R antibody level was positively correlated with 24-hour urine protein(r=0.803,P＜0.01) and negatively correlated with serum albumin in IMN patients (r=-0.816,P＜0.01). Conclusions The high positive ratio of anti-PLA2R antibody may indicate that it is the specific autoantibody in IMN.AntiPLA2R antibody is correlated with IMN disease severity,which indicates that it may be the pathogenic autoantibody in IMN.
