ObjectiveTo investigate intrapulmonary expression of ICAM-1 mRNA and the relationship between the expression of ICAM-1 and lung injury in ANP. Methods ANP was reproduced by retrograde injection of 3.5% sodium taurocholate. Animals were sacrificed at 1,4,12 and 24 hours after induction of pancreatitis. Intrapulmonary ICAM-1 mRNA expression was assayed by reverse transcription-PCR. The following parameters were also measured: Serum amylase, histologic grading of lung injury and intrapulmonary myeloperoxidase (MPO). ResultsThere was intrapulmonary overexpression of the ICAM-1 mRNA on the first hour and persisted up to 12-24 hours with the increase of serum amylase and intrapulmonary MPO after pancreatitis induction. Score of the lung injury correlated well with the expression of the ICAM-1 mRNA and intrapulmonary MPO (r=0.85, 0.85 and 0.96, all P

OBJECTIVE: To explore whether there are beta-amyloid protein (Abeta) binding elements in heart-beneficial recipe (HBR, a compound traditional Chinese herbal medicine), which can ameliorate the cytotoxicity of Abeta. METHODS: The extract of HBR and Abeta(1-40) were co-precipitated, and the Abeta(1-40) in pellets was detected by immunoblotting. Affi-gel-Abeta(1-40) was constructed, and Affi-gel-Abeta(1-40) affinity elements from the extract of HBR were analyzed by high-performance liquid chromatography (HPLC). The assay of lactic dehydrogenase (LDH) release from the primary cultured rat cortex neurons was used to evaluate the cytotoxicity of Abeta(1-42), and the protection effects of the HBR serum and the Affi-gel-Abeta(1-40) treated HBR serum. RESULTS: Immunoblotting examination showed Abeta(1-40) could be co-precipitated with components of HBR following co-incubation, and the amount of Abeta(1-40) within pellets decreased when the HBR extract was diluted. Abeta(1-40) affinity elements from the extract of HBR, eluted from Affi-gel-Abeta(1-40) by glycine solution (pH=2.5), could be detected by HPLC-fluorescent detector system. The analysis of LDH release showed that exposure of neurons to 5 micromol/L Abeta(1-42) for 48 h caused a significant increase of LDH release in either a serum free or 10% serum contained culture condition (P<0.01). The rat HBR serum was able to suppress Abeta(1-42) induced LDH release (P<0.05), whereas Affi-gel-Abeta(1-40) treated HBR serum still maintained the ability to attenuate Abeta(1-42) induced LDH release although the effect was somewhat decreased compared with Affi-gel treated HBR serum. CONCLUSION: There are Abeta affinity components in HBR, which could not increase the Abeta cytotoxicity, but might be able to inhibit the cytotoxicity of Abeta. The results implied that the exploration of Abeta affinity elements from Chinese medicinal recipe which is effective for Alzheimer disease, might be an important direction in Alzheimer disease therapeutic research area.

Objective To evaluate the effects of repeated sevoflurane anesthesia on long-term cognitive function in lactating rats.Methods Twenty-four healthy Spragne-Dawley rats,aged 7 days,weighing 14-17 g,were randomly divided into 3 groups (n =8 each):control group (group C),2.6 ％ sevoflurane group (group S1),and 1.5％ sevoflurane group (group S2).At 7,14 and 21 days after birth,2.6％ and 1.5％ sevoflurane and carrier gas were inhaled for 1 h in groups S1,S2 and C,respectively.Visible plafform trial was carried out on 28 and 29 days after birth,and the swimming speed of the rats was recorded.Place navigation test was performed on 32-36 days after birth,and the escape latency was recorded.Spatial probe test was carried out on 36 days after birth,and the time spent in the platform quadrant,swimming distance and the number of times crossing the platform quadrant was recorded.Results Compared with group C,the escape latency was significantly prolonged in groups S1 and S2 (P ＜ 0.05).The escape latency was significantly longer in group S1 than in group S2 (P ＜0.05).There were no significant differences between the three groups in the swimming speed,time spent in the platform zone,swimming distance and the number of times crossing the platform quadrant (P ＞ 0.05).Conclusion Repeated inhalation of sevoflurane during lactation can impair the long-term declarative memory,which is concentration-related,while it has no effects on the associative learning in rats.

Objective To investigate the effect of a selective cyclooxygenase-2 inhibitor on tumor metastasis,tumor angiogenesis,and vascular endothelial growth factor(VEGF)of orthotopic implanted human gastric carcinoma in non.obesity diabetes(NOD)severe combined immune deficiency(SCID)mice.Methods Human gastric cancer SGC-7901 tissues were orthotopically implanted into the stomach of the NOD SCID mice.Forty mice were randomly divided into two groups which received either intravenous injections of 0.9% Nacl solution (0.9% NaCL solution group)or 50mg/kg.d Nimesulide(Nimesulide group)twice weekly for two weeks.Mice were sacrificed in the 5th week after implantation.Tissues from stomach and other organs were obtained for histopathologieal evaluation.The intratumoral microvessel density(MVD)and VEGF protein expression in tumor were evaluated by immunochemical method.Results The tumor metastasis rates were 18/20 in 0.9% Nacl solution group and 5/20 in Nimesulide group(P＜0.05).MVD was 9.5±2.9 in 0.9% NaCl solution group and 3.9±2.1 in Nimesulide group(P＜0.01).VEGF protein expression was 90% in 0.9%NaCl solution group and 25% in Nimesulide group(P＜0.01).Conclusions Nimesulide can inhibit the metastasis or gastric cancer through inhibiting tumor VEGF expression and tumor angiogenesis with no obvious anticoagulant activity.

Objective:To observe the clinical curative effect of integrated traditional Chinese and western medicine in the treat-ment of patients with ocular herpes zoster. Methods:Seventy patients with ocular herpes zoster in our hospital were selected during De-cember 2011 to December 2013. According to random number table,the patients were divided into two groups. The patients in the con-trol group were treated with ganciclovir 5. 0 mg·kg-1 ·h-1 , ivd, qd and ganciclovir ophthalmic gel, qid. The patients in the observa-tion group were treated with Banlangen granules and acupuncture additionally. The clinical efficacy, the time of blistering, pain and crusting and adverse reactions in the two groups were observed and compared. Results:After the treatment, the effective rate of the ob-servation group was 94. 29% , while that of the control group was 77. 14% (P<0. 05). The time of blistering, pain and crusting in the observation group was significantly shorter than that in the control group (P<0. 05). The incidence of adverse reactions of the ob-servation group was 2. 86%, while that of the control group was 11. 43%(P>0. 05). Conclusion:The clinical efficacy of integrated traditional Chinese and western medicine in the treatment of ocular herpes zoster is obviously better than that of western medicine treat-ment alone with fewer adverse reactions and shorter time of blistering, pain and crusting.

Objective To investigate the effect of sevoflurane anesthesia on the expression of hippocampal apolipoprotein E (ApoE) mRNA of rats.Methods Sixty healthy male Sprague-Dawley rats,weighing 300-400 g,aged 15 weeks,were randomly divided into 2 groups (n=30 each) using a random number table:50％ oxygen group (group C) and 3.2％ sevoflurane group (group S).The rats in group C inhaled 50％ oxygen for 2 h,while those in group S inhaled 3.2％ sevoflurane in 50％ oxygen for 2 h.Morris water maze test was carried out before anesthesia and at 24 and 72 h after anesthesia.At 2,24 and 72 h after anesthesia,hippocampal specimens were obtained for determination of the expression of ApoE mRNA by RT-PCR.Results Compared with group C,no significant change was found in the escape latency,time of staying at the original platform quadrant,frequency of crossing the original platform,and swimming distance before and after anesthesia,and the expression of ApoE mRNA was up-regulated after anesthesia in group S.There was no significant difference in the escape latency,time of staying at the original platform quadrant,frequency of crossing the original platform,and swimming distance before and after anesthesia,and expression of ApoE mRNA at each time point after anesthesia between the two groups.Conclusion Cognitive dysfunction induced by sevoflurane has no relationship with the up-regulated expression of ApoE mRNA in the hippocampus of rats.

Objective To explore the exercise risk of urban residents aged18 to 65 years old.MethodsHealth screening and cardiovascular risk stratification were performed among adults18 to 65 years old in 2010by using exercise risk assessmentrecommendedbyAmerican College of Sports Medicine.Result A total of15 498 subjects were recruited 9293 males and 6205 females,mean age (44.8 ±11.1) years,8929(57.6％ ) in the lower risk group,5323(34.3％ ) in the moderate risk group,and 1246(8.1％ ) in the higher risk group.The proportion of those in the higher risk group was increased with age.Conclusion Risk assessment and Physical Activity Readiness Questionnaires should be used before physical activity programme is initiated,especially in middle aged or elderly people.

Objective To explore the relationship between glycosylated hemoglobin and pulse wave velocity in non-diabetic elderly people.Methods Totally 163 subjects were included after exclusion of liver or kidney disfunction,diabetes mellitus or malignant tumor.They were divided into two groups:group A (HbA1c＜5.7％) (n＝54) and group B (HbA1c 5.7％-6.4％)(n＝109).The age,pulse wave velocity,systolic blood pressure,diastolic blood pressure,blood chemistry and hypertension were compared between the two groups.Multi factor analyse was conducted to analyze the relative factors for pulse wave velocity.Results Systolic blood pressure was higher in group B than in group A (P ＜ 0.05).Multi-linear stepwise regression analyses suggested that age,hypertension,glycosylated hemoglobin were positively related to pulse wave velocity in non-diabetic elderly people (β values were 20.382,144.061,93.195,all P＜0.10).Conclusions Glycosylated hemoglobin is related to arterial stiffness in non-diabetic elderly people,it can be used as a predictive and control target of cardiovascular and cerebrovascular disease in old people.
