Objective To investigate the effects of Qi-reinforcing and blood-activating prescription,Qidan Tongmai Tablet(QDTMT) on the IL-10 in the rat model of myocardial ischemia/reperfusion injury.Methods A model of myocardial ischemia/reperfusion injury was reproduced by ligation of left anterior descending branch of the coronary artery.Thirty-six male SD rats were randomly divided into six groups(n=6):sham operation group,model group,Diltiazem Hydrochloride group,QDTMT high-dose group,QDTMT medium-dose group and QDTMT low-dose group.After the left anterior descending branch of coronary artery was occluded for 30 minutes followed by reperfusion for 2 hours,the whole blood was collected via right common carotid artery and the serum level of IL-10 was measured by ELISA.At the same time,HE staining was performed to detect the pathological change in myocardium,and the ultrastructural alterations of rats were observed with transmission electron microscope.Results The contents of IL-10 in serum were increased in QDTMT groups.Electron microscopic examination showed that pathologic changes of myocardiocytes in QDTMT groups were milder than those of the model group.The effects in QDTMT high-dose group were better than that in the low-dose group,and has insignificant difference with Diltiazem Hydrochloride group.Conclusion Qi-reinforcing and blood-activating prescription inhibits the inflammatory reaction by facilitating the expression of endogenous IL-10 and improving myocardial ultrastructural changes after myocardial ischemia/reperfusion in rats.These actions may contribute to its protective effect on the ischemic myocardial cells.

Background miRNAs are a group of non-coding small RNA molecules,and they play an important role in regulating the apoptosis of LECs.The biological effects and mechanisams of miRNAs on LECs in agerelated cataract still need to be further elucidated.Objective This study was to investigate the anti-oxidative effects of miR-204 on age-related cataract in vitro.Methods The specimens of anterior lens capsules from agerelated cataract patients and normal donors were collected in Shandong Eye Institution and 20 subjects for each.The expression level of miR-204 was detected and compared between cataractous eyes and normol eyes by real-time fluorescence quantitative PCR (RT-qPCR).HLE-B3 cells,a human LEC line,were cultured,and the oxydative stress models of LECs were established by adding 200 μmol/L H2 O2 in the medium.The models were divided into model control group,miR-204 agomir group,agomir negative control group,miR-204 antgomir group and antagomir negative control group according to the difference of tranfected agents,and normal cells served as the control group.Twenty-four hours after transfection,the expression levels of miR-204 mRNA in the cells of various groups were detected by RT-qPCR to varify the transfection rate.Apoptosis rate of the cells was assayed by flow cytometry.The relative expression levels of TP53INP1 mRNA and p53 mRNA as well as their proteins were detected by RT-qPCR and Western blot,respectively.Results The mean expression level of miR-204 was significantly lower in the anterior lens capsules of cataractous eyes than that in the normal eyes (t=14.21,P＜0.05).The mean apoptosis rate of cells was 1.31±0.12,4.90±0.28,2.60±0.15,4.39±0.20,5.74±0.13 and 4.34±0.63 in the normal control group,model control group,miR-204 agomir group,agomir negative control group,miR-204 antgomir group and antagomir negative control group,respectively.The apoptosis rate was significantly increased in the model control group compared with the normal control group (t =-20.69,P＜0.01) and the apoptosis rate was also increased in the miR-204 antagomir group compared with antagomir negative control group (t =3.79,P＜0.05);while the apoptosis rate in the miR-204 agomir group was significantly declined in comparison with agomir negative control group (t=-12.20,P＜0.01).The relative expression levels of TP53INP1 and p53 mRNA and proteins in the cells were significantly higher in the model control group than those in normal control group (mRNA:t =6.44,11.71,both at P＜0.0I;protein:t =10.72,19.40,both at P＜0.01),and so were between the miR-204 antagomir group and antagomir negative control group (mRNA:t =4.07,3.74,both at P＜ 0.05;protein:t =7.18,10.58,both at P＜0.05).However,the expression levels of TP53INP1 and p53 mRNA and protein were significantly reduced in the miR-204 agomir group in comparison with the agomir negative control group (mRNA:t =-19.28,-10.58,both at P＜0.05;protein:t=-6.50,-6.36,both at P＜0.05).Conclusions miR-204 induces oxidative damage of age-related cataract via targeting TP53INP1,which suggests that the activation of TP53INP1-p53 signaling may be involved in the development of age-related cataract.

Three patients with carotid body tumor were treated by surgery in our department from 1994 to 1998. There were 3 females with age from 23 to 40 years old. Among 3 cases, 2 cases were misdiagnosis as neurilemmoma before operation. The size of tumor was 2.5×2.5cm in 1, 3.0×3.0cm in 2. The treatment methods were surgery alone in 2, combined radiotherapy in 1. All patients were cured who had not serious complications. We think that the three symptoms of carotid body tumor are important bases for diagnosis on this disease. However, color B ultrasonography, DSA, CT or MRI also provided informations for useful diagnosis.

Objective To study the diagnostic value of air plethysmography (APG) in deep venous valvular incompetence of lower limbs and the relationship between deep venous reflux and calf muscular pump function. Methods Sixty-five varicose cases (89 limbs) were detected by APG in alterations of venous filling index (VFI), ejection fraction(EF), residual volume fraction(RVF) and outflow fraction(OF). Of 89 limbs, 18 limbs were in GradeⅠ of deep venous reflux, 24 in Grade Ⅱ, 18 in Grade Ⅲ and 12 in Grade Ⅳ. Integrated vectors analysis (Hotelling T 2test) was done with these index. Venography was performed in all patients. Results There were statistical differences in VFI between each two Grades of deep venous reflux except for between Grade Ⅰ and Ⅱ. There were also statistical differences in EF,RVF and OF between Grade Ⅳ and the other Grades. Hotelling T 2test showed significant testing efficiency of APG. ConclusionsDeep venous valvular insufficiency of lower limbs can be assessed by APG. VFI is a reliable quantitative index for evaluating the degree of deep venous reflux. There may be an exponent relation between deep venous reflux and calf muscular pump function.

Objective To evaluate the role of δ receptor in reduction of hypoxia-reoxygenation (H/R) injury to cardiomyocytes by morphine preconditioning in rats with chronic heart failure.Methods Adult male Sprauge-Dawley rats weighing 220-250 g were used in the study.Chronic heart failure was induced by injection of adriamycin 2 mg/kg via the tail vein once a week for 6 weeks.Their hearts were removed 2 weeks after the last injection and the cardiomyocytes were isolated and cultured.The cells were randomly divided into 5 groups ( n =8 each):control group (group C); H/R group; morphine preconditioning group (group MPC); morphine preconditioning + naloxone (opioid receptor antagonist ) group (group MPC + Naloxone) ; morphine preconditioning + naltrindole ( δ receptor antagonist) group ( MPC + Naltrindole group).The cells were cultured in normal culture atmosphere in group C and were exposed in hypoxic air for 3 h followed by 1 h reoxygenation in the other groups.Morphine preconditioning was performed immediately before hypoxia in group MPC.Naloxone and naltrindole were added before morphine preconditioning in groups MPC + Naloxone and MPC + Natrindole respectively.At 1 h of reoxygenation,the cell viability ( by MTT assay),activities of lactate dehydrogenase ( LDH ) and creatine kinase (CK),and cell apoptosis were detected.The apoptotic rate was calculated.Results The cell viability was significantly lower,and the activities of LDH and CK and apoptotic rate were significantly higher in groups H/R,MPC + Naloxone and MPC + Natrindole than in group C (P ＜ 0.05).The cell viability was significantly higher,and the activities of LDH and CK and apoptotic rate were significantly lower in group MPC than in group H/R ( P ＜ 0.05).Conclusion Morphine preconditioning reduces H/R injury to cardiomyocytes through activating δ receptor in rats with chronic heart failure.

Objective To investigate the expression of p53 up-regulated modulator of apoptosis (PUMA) and p53 protein and relationship with clinicopatbological parameters in human gastric cancers. Methods Primary gastric carcinoma and adjacent normal mucosa were obtained from 84 consecutively enrolled patients undergoing gastric cancer resection at Peking University People's Hospital during the period from April 2001 to May 2003. Immunohistochemistry staining was used to measure the expression of PUMA and p53 proteins both in normal and malignant tissues. Results PUMA expression is significantly weaker in primary gastric carcinoma compared to adjacent normal mucosa (P <0. 01 ). Weak PUMA expression in gastric cancer correlates with depth of tumor invasion ( P < 0. 01 ), advanced pTNM stage ( P < 0. 05 ) and poor overall survival of patients ( P < 0. 05 ). p53 protein expression in gastric carcinoma is significantly higher than adjacent normal mucosa ( P < 0. 01 ). There was a significant negative correlation between the expression of PUMA protein and p53 protein in gastric carcinoma (P < 0. 05 ). Conclusion PUMA expression in gastric carcinoma is significantly lower compared to adjacent normal mucosa. Weak PUMA expression in gastric cancer correlates with depth of tumor invasion, later pTNM stage and poor overall patient survival.

Objective To explore a high molluscicidal efficient method in special Oncomelania hupensis snail environments. Methods In 2005 and 2006,in large special environments(rubble creek beaches and seepage barren hills with snails),the me-chanical soil-buried method(excavator digging to bury deep snails)and manual soil-buried method were used respectively,and the results were compared for the cost-effectiveness. Results With the mechanical soil-buried method in 2006,the investment was 0.78 yuan/m2,and the compression rate of snail areas was 100%;with the manual soil-buried method in 2005,the investment was 1.34 yuan/m2,and the compression rate of snail areas was 20.26%. The former was much better than the latter. Conclusion In the large special environments with snails,the mechanical soil-buried method is superior to manual soil-buried method.
