Objective To examine the effects of intravenous thrombolysis with Tissue-type plasminogen activator (rt-PA) combined with mild hypothermia therapy on patients with acute cerebral infarction and further investigate under?lying mechanism for the treatment of cerebral infarction. Methods Sixty cases of cerebral infarction patients were random?ly divided into three groups with 20 patients in each group:①The control group was given rt-PA intravenous thromboly?sis;②The treatment group 1:intravenous thrombolytic therapy combined with local mild hypothermia treatment for 12 h;③The treatment group 2:intravenous thrombolytic therapy and local mild hypothermia in the treatment of 24 h. We col?lected NIHSS score before and after thrombolytic therapy, patient monitoring (ICP) changes during thrombolytic therapy, March (MRS) score and complications during follow-up after thrombolysis, The serum levels of SOD and MDA were as? sessed before and after thrombolytic therapy. Results NIHSS score was lower in both treatment group 1 and treatment group 2 than in the control group (P<0.05) at 72 h, 7 d, 14 d after thrombolysis. MRS was lower in both treatment group 1 and treatment group 2 than in the control group (P<0.05) at 3 months after thrombolytic therapy. MRS were lower in treat?ment group 2 than in the treatment group 1 (P<0.05). ICP in treatment group 1 and the concentration of MDA in treat?ment group 2 were lower, compared with control group (P<0.05) at 24 h, 72 h and 7 d after thrombolysis. ICP was lower in treatment group 2 than treatment group 1 at 7d after thrombolysis. The concentration of SOD was higher in treatment groups than in control group (P<0.05) at 24, 72 h and 7d after thrombolysis. ICP and MDA concentration were lower in treatment group 2 than in treatment group 1(P<0.05) at 72h and 7d after thrombolysis. The concentration of SOD was higher in treatment group 2 than in the treatment group 1 at 7 d after thrombolysis (P<0.05). There was no significant dif?ference in adverse events and mortality among groups (P>0.05). Conclusion Rt-PA intravenous thrombolysis combined with mild hypothermia treatment can improve the prognosis of patients with cerebral infarction without increasing the inci?dence of adverse reactions. In addition, thrombolysis combined with mild hypothermia 24 h has better effect than with mild hypothermia 12 h. The beneficial effects may be accomplished by reducing oxidative stress reaction.

Objective To observe the clinical effect of the club exercise designed ourselves on the prevention of should-hand syndromeafter stroke. Methods 100 stroke patients in early stage, whose motor function of upper limb were lower than Grade Ⅲ evaluated byBrunnstrom assessment and without shoulder pain and swelling of hand, were randomly divided into control group (n=50) and observationgroup (n=50). All of them received routine rehabilitation therapy, and the observation group received club exercise in addition. The incidenceof shoulder pain, the active range of motion of shoulder, the motor function of upper limb and activities of daily living (ADL) of 2groups were evaluated before and 2 courses (60 d) after treatment. Results There was no statistical difference between 2 groups before thetreatment (P>0.05). After 2-course treatment, the incidence of shoulder pain was significantly lower in the observation group than in the controlgroup (P<0.001), the active range of motion of shoulder, motor function of upper limb and ADL were significantly better in the observationgroup than in the control group (P<0.001). Conclusion The club exercise can prevent the pain of shoulder joint, increase the activerange of motion of shoulder joint and improve the motor function of upper limb and ADL in patients after stroke.

Objective To investigate the clinical factors influencing the treatment efficacy of microsurgery on patients with cerebral arteriovenous malformations (AVMs). Methods One hundred and eleven patients,admitted to our hospitals from January 1,2003 to December 31,2009 and underwent microsurgical cerebral AVMs resection were chosen in our study; their clinical data were retrospectively analyzed.The functional neurological status was classified with modified Rankin scale 7 d and 6 months after surgery. Binary logistic regression models were applied to test the effect of patient gender, age,intra-cerebral hemorrhage,and the size,deep venous drainage pattern and location of AVMs on long-term and short-term treatment efficacy. Results Twenty-nine patients (26.1％) showed new neurological deficits 7 d after the surgery.Univariate analysis and multivariate analysis demonstrated that deep venous drainage, eloquent location and large size of AVMs, high Spetzler-Martin grading aneurysms and no intra-cerebral hemorrhage were significantly associated with new early neurological deficits (P＜0.05),while gender and age of the patients had no significant association with new early neurological deficits (P＞0.05).The scores of neurological status scale in patients with Spetzler-Martin grading Ⅰ,Ⅱ and Ⅲ were significantly different between 7 d and 6 months after the surgery (P＜0.05). Conclusion AVMs patients having deep venous drainage,eloquent location and large size of AVMs,and having aneurysm and intra-cerebral hemorrhage may be the risk factors of new early neurological deficit after microsurgical resection; analyzing the Spetzler-Martin grading before surgery can help to determine the treatment options.

OBJECTIVETo investigate the effect of aluminum chloride on dissociated Ca(2+) in hippocampus neuron cells in mice and the relationship to the learning and memory.

METHODSMale ICR mice in the three intoxicated groups were administered with the double distilled water containing AlCl(3) (10, 50, 300 mg.kg(-1).d(-1)) while those in the control group were administered with the double distilled water for 100 days. The methods of behavior toxicology such as Morris swim maze were used for studying the effect of aluminum chloride on the changes of learning and memory in mice. With calcium sensitive fluorescence indicator Fura-2 as the fluorescent probe, the influence of the subchronic exposure to Al on the dissociated Ca(2+) in hippocampus neuron cells was observed.

RESULTSThe dissociated Ca(2+) in hippocampus neuron cells in the middle dosage group and the high dosage group [(412.25 +/- 53.20), (467.37 +/- 32.85) times] was lower than those in the control group [(293.91 +/- 32.21) times] respectively (P < 0.01), and correlated positively with the dose and dissociated Ca(2+) (r = 0.861, P < 0.01). Compared with the control group, the latent period was lengthened (P < 0.05) in the middle dosage and the high dosage group.

CONCLUSIONThe subchronic exposure to AlCl(3) in mice affects the dissociated Ca(2+) in hippocampus neuron cells. The increase of dissociated Ca(2+) in hippocampus neuron cells may be correlated with the disfunction of cognition in the aluminium intoxicated mice.

Objective To study the therapeutic effects of human umbilical cord mesenchymal stem cells (hUCMSCs) on acute liver failure ( ALF) induced by D-galactosamine (D-gal) and lipopolysaccharide (LPS) in rats. Methods The ALF model was obtained through intraperitoneal injection of D-gal(300 mg/kg)and LPS (20μg/kg)in Wister rats. The hUCMSCs were transplanted after intoxication. All rats were divided into four groups, and each group received either hUCMSCs or 0.9% NaCl solution through intraperitoneal or tail-intravenous injection. To evaluate the liver function of each group, the levels of alanine aminotransferase (ALT), total bilirubin (TBil) and serum albumin (Alb) were measured on the day of hUCMSCs transplantation and the following 1, 2, 3, 5 and 7 days. All rats were then sacrificed to examine the liver histology at day 7. Analyses were done by using Fisher's exact test, unpaired t test and Mann-Whitney U test. Results There were no significant differences of survival rates among four groups (Fisher's exact test, both P = 1. 00). The levels of ALT, TBil and Alb in group receiving hUCMSCs intraperitoneally were (804. 9 ± 88. 0) U/L,(17. 4±2. 7) μmol/L and (20. 9±0. 8) g/L, respectively after 2 days of injection, whereas in the corresponding control group, those were (1294. 3± 171. 4) U/L, (32. 3±5. 5) μmol/L and (16. 1±0. 9) g/L, respectively, which indicated that hUCMSCs transplantation significantly improved the liver function (t = 2. 640, P =0.020;t=2.529, P = 0. 025;t= - 3. 833, P = 0. 002). Both of hUCMSCs-transplanted groups showed no significant differences. Liver histological data showed that transplantation of hUSMSCs through either intraperitoneal or tail-intravenous injection alleviated liver damage (U=4. 500, P = 0. 005;U=4. 500, P = 0. 008) and the mitotic index also increased in hUCMSCs-transplanted groups (U=4. 000, P = 0. 005; U=5. 500, P = 0. 013). Conclusions The levels of ALT, TBil and Alb can rapidly normalize in ALF rats after injected with hUCMSCs either intraperitoneally or tail-intravenously. hUCMSCs application raises the mitotic index, enhances hepatocellular regeneration and improves histological status.

Background and purpose:Vascular endothelial growth factor(VEGF) is a potent angiogenic mediator and angiogenesis has important effects on tumor growth and metastasis.The present study was to investigate the relationship between genetic polymorphism of VEGF and heredity risk factor of lung cancer.Methods:VEGF genotypes were determined by PCR-RFLP method in 171 patients with lung cancer and 172 healthy controls.Software PHASE 1.0 was used to construct the haplotypes of every individual.Unconditional logistic regression model was used to analyze the statistical association of genotypes or haplotypes in the two groups adjusted by gender and age. Results:Individuals with at least one-2578A allele had a significantly decreased risk of lung cancer compared with those carrying-2578CC genotype.When the analyses were stratified by gender,the combined-2578 CA and AA genotype,were associated with a considerably reduced risk of lung cancer(P=0.001,OR=0.303,95%CI=0.15 3-0.601).The distribution of the two haplotypes(936C/-2578C and 936C/-2578A) among overall lung cancer cases was significantly different from that among the controls(P=0.016,0R=0.317,95%CI=0.124-0.809 and P=0.018,OR=0.547, 95%CI=0.331-0.903).When the cases were categorized by tumor histology,the distribution of C-C haplotype in the adenocarcinoma(AC) group was associated with a substantially lowered risk of AC(P=0.004,0R=0.237,95%CI=0.090- 0.627),compared with the reference haplotypes.Conclusion:VEGF polymorphism may be a critical risk for the genetic risk factor to lung cancer.
