Objective : To examine the effect of moderate aerobic exercise on the 10-year risk of atherosclerotic cardiovascular disease (ASCVD) in patients with hypercholesterolemia, so as to provide insights into ASCVD prevention. Methods : The patients with hypercholesterolemia admitted to the Affiliated Hospital of Hebei University from September 2019 to September 2020 were recruited and randomly assigned into the intervention group and the control group using a random number table. Participants in both groups received routine lipid-lowering therapy and health education, and participants in the intervention group were given additional interventions of moderate aerobic exercise. Serum lipid levels were measured before and after 12 weeks of interventions. The 10-year risk of developing ASCVD was evaluated in both groups following interventions. Results : There were 50 participants with hypercholesterolemia in each of the intervention and control groups. The mean age was ( 38.80±1.42 ) years in the intervention group and ( 37.14±1.23 ) years in the control group, and males were accounted for 46.00% and 40.00%, respectively. The increase in high-density lipoprotein cholesterol ( HDL-C ), the reduction in total cholesterol ( TC ), triglyceride ( TG ), low-density lipoprotein cholesterol ( LDL-C ) and the 10-year risk of ASCVD were all significantly greater in the intervention group than those in the control group before and after the interventions ( P<0.05 ). Conclusion Moderate aerobic exercise may reduce the 10-year risk of ASCVD through regulating blood lipid levels.

AIMTo investigate the intestinal absorption of silybin (SLB) in male rats.

METHODSSingle-pass intestinal perfusion (SPIP) technique was performed in each isolated region of the small intestine at a flow rate of 0.1 mL x min(-1). The samples of perfusate and portal plasma were collected at the designated periods of time after rat intestinal perfusion and analyzed for drug by HPLC.

RESULTSThe absorption rate constant (k(a)) and the effective permeability (P(eff)) of SLB at 190 microg x mL(-1) were determined for each segment. These data indicated the absorption rate were duodenum > jejunum > ileum > colon. SPIP was also performed in duodenum with three concentrations of SLB (80, 190 and 300 microg x mL(-1)). The concentration dependent changes of k(a) and P(eff) were evident in the duodenum perfusion of silybin. At silybin perfusate concentrations of 80 microg x mL(-1), k(a) and P(eff) were different from the values at either of the two higher concentrations (190 and 300 microg x mL(-1), P < 0.05). However there was no difference between 190 microg x mL(-1) and 300 microg x mL(-1) groups. The drug mass appearing in the plasma further indicated the absorption were duodenum > jejunum > ileum > colon.

CONCLUSIONSLB can be absorbed in whole intestinal sections. When the concentration raises to a certain level, the uptake of SLB will not increase.

Objective To investigate the significance of serum CD25 / serum ferritin in the diagnosis of lymphoma-associated hemophagocytic syndrome (LAHS),so as to provide the clinical basis for improving its recognition and giving effective therapy. Methods The serums were collected from 70 patients with hemophagocytic syndrom in Beijing Friendship Hospital, Capital Medical University during the period from October 2008 to June 2011, including 31 LAHS cases and 39 other disease-associated HPS cases. The serum CD25 level in HPS patients was measured with enzyme-linked immunosorbent assay (ELISA), and the serum ferritin was measured on the same day. Then the serum CD25/ferritin ratio was calculated and the differences of the serum CD25, serum ferritin and serum CD25/ferritin ratio between two groups were compared. Results The variance of serum CD25 [(15760.52±7851.74) pg/ml vs (12727.41±11285.28) pg/ml,t=-1.78,P=0.075] and serum ferritin levels (1750.00 ng/ml vs 2947.00 ng/ml,Z=-1.490,P=0.136)were not statistically significant between two groups,while the serum CD25/serum ferritin ratio in LAHS patients was significantly higher than the other group(8.57×10-3 vs 2.84×10-3,Z=-2.106,P=0.035).Conclusion The serum CD25/ serum ferritin ratio is statistically higher in LAHS patients, which might be a novel useful marker for predicting underlying malignant lymphoma in HPS patients.

This paper introduces a monitor that can monitor five physiological parameters (ECG, blood pressure, spo2, respiration and temperature) based on Wireless Sensor Networks. The monitor will be applied to hyperbaric oxygen chambers. After acquisition, the signal will be displayed on the LCD screen of the monitor terminal in the cabin. At the same time, the Zigbee RF module will send the signal to the extravehicular guardianship PC terminals. This monitor equipment can realize synchronous real-time monitoring both inside and outside. What's more? A host can also display monitoring data the three monitor terminals collected. Preliminary clinical tests show that the monitors are safe and the monitoring results are satisfactory.

Objective To prepare the 99Tcm-survivin mRNA antisense peptide nucleic acid (PNA)and investigate its value as a gene imaging agent in tumor bearing mice and early diagnosis in tumor.Methods Survivin mRNA antisense PNA and mismatch PNA were synthesized.Four amino acids (Gly- (D)Ala-Gly-Gly) and Aba (4-aminobutyric acid) were linked to the 5' end of PNA.Gly- (D)Ala-Gly-Gly served as a chelating moiety for strong chelation of 99Tcm and Aba acted as a spacer to minimize the steric hindrance.PNAs were labeled with 99Tcm by the ligand-exchange method.The labeling efficiency and radiochemical purity were measured by HPLC and ITLC methods.There were five BALB/c nude mice bearing human lung carcinoma ( A549 ) in each of antisense PNA and mismatch PNA groups.Gene imaging of 99Tcm-survivin mRNA antisense and mismatch PNAs were performed at 1,2 and 4 h post the injection,respectively,and the T/NT ratio was measured by the method of ROI.The statistical comparisons of average values were performed with the two-group t-test for independent sample by SPSS 13.0.Results The product kept stable in vitro.The labeling efficiency of 99Tcm-survivin mRNA antisense PNA was (95.48 ±1.92)％ and more than 85％ after the incubation for24 h in serum.The radiochemical purity was ＞ 95％.The labeling efficiency of mismatch PNA was similar to the antisense PNA.99Tcm-survivin mRNA antisense PNA was especially uptaken by tumor lesion,and its accumulation reached the top at 4 h post the injection.T/NT ratios at 1,2,and 4 h were 2.70 ± 0.28,3.44 ± 0.35,4.21 ± 0.63,respectively.In the comparison,the T/NT ratio of 99Tcm-survivin mRNA mismatch PNA at 4 h (3.12 ±0.50) was significantly lower (t =2.918,P =0.019).Conclusions 99Tcm-survivin mRNA antisense PNA has high labeling efficiency,good stability and no need of purification.Its characteristic of especial uptake by tumor lesion provides the potential value in early diagnosis of tumor.

In order to investigate the expression of serum sHLA-G in hemophagocytic syndrome (HPS) patients and to evaluate its clinical significance, the clinical data of HPS patients in Capital Medical University Beijing Friendship Hospital during the period from September 2008 to July 2010 were collected. They were divided into infection-associated HPS, tumor-associated HPS and rheumatological disease-associated HPS according to cause of diseases. The serum concentration of sHLA-G in HPS patients and 25 healthy controls was measured by enzyme-linked immunosorbent assay (ELISA), the correlations between sHLA-G level and laboratory indicators were analyzed. The results showed that the level of serum sHLA-G in HPS patients was significantly higher than that in healthy controls (p = 0.003), but the difference was not statistically significant between HPS groups of different causes (p = 0.233). The positive correlation of sHLA-G level in HPS patients with platelet count was found, but there was no positive correlation of their sHLA-G levels with WBC, Hb, Plt, ALT, AST, LDH, Alb, TBil, DBil, IBil, Cr, BUN, TG, fibrinogen and ferritin levels detected on same day. It is concluded that the the increase of serum sHLA-G levels in HPS patients may be caused by different factors such as infection, tumor, T cell activation and over-stimulation of several cytokines. sHLA-G can inhibit NK cell activity, resulting in formation of abnormal immune storm, and may be play a role in the pathogenesis of HPS.

The aim of this study was to investigate the influence of neonatal isolation stress on hyperlocomotion in complexin II knockout mouse (Cplx2(-/-)). The mice were randomly divided into 4 groups: Cplx2(-/-) with stress, Cplx2(+/+) with stress, Cplx2(-/-) without stress and Cplx2(+/+) without stress. Isolation stress was employed on the pups of stress groups from the 2nd day after the postnatal to the 21st day. The PCR was used to determine the gene type and the hyperlocomotion test was employed to detect the change of animal behavior after methamphetamine or saline injection (i.p.). The results showed that the animals of all groups increased their movement after injection of 0.2 mg/kg methamphetamine in different levels (P < 0.01), compared with those injected with saline. The Cplx2(-/-) mouse with stress revealed a significant increase in the distance of free movement after injection of 0.2 mg/kg methamphetamine compared with the knockout mouse without stress (P < 0.001). When Cplx2(-/-) mouse with stress was compared with wild type with stress, Cplx2(-/-) mouse with stress had more movement (P < 0.001), indicating that Cplx2 has effect on the hyperlocomotion as well. These results suggest an involvement of stress and Cplx2 in the movement behavior of mice.

AIM:To investigate the angiogenic effect and mechanisms of astragaloside IV(AS-IV)in rats with myocardial infarction via protein kinase D 1(PKD1)-histone deacetylase 5(HDAC5)-vascular endothelial growth factor (VEGF)signaling pathway.METHODS:The classic model of myocardial infarction by ligation of the left anterior de-scending coronary artery was replicated,and the rats were randomly divided into model group,AS-IV group,and AS-IV+CID755673(PKD1 inhibitor)group.The sham operation control group and DMSO control group were also set up.All the rats were given intravenous injection via caudal vein.The rats were sacrificed 4 weeks later,and segmental heart samples were used for HE staining and Masson staining.The expression of PKD1,HDAC5 and VEGF was analyzed by immunohis-tochemistry,RT-PCR and and Western blot.RESULTS:Compared with sham operation group and DMSO group,the myo-cardium in model group showed disordered arrangement, accompanied with necrotic myocardial cells and obvious fibrosis tissue.After treatment with AS-IV,the morphological changes of myocardium were obviously improved,and the number of new blood vessels increased significantly.However,after treatment with AS-IV+CID755673,the myocardial tissues of the rats became disordered again,with increased necrotic cells and some closed vessels.The mRNA and protein expression of PKD1,HDAC5 and VEGF in myocardial tissue in model group was significantly lower than that in sham operation and DMSO groups(P<0.05).The expression in AS-IV group was significantly higher than that in model group(P<0.01), while that in AS-IV+CID755673 group was significantly lower than that in AS-IV group(P<0.05).CONCLUSION:AS-IV promotes the angiogenesis of myocardial tissues in the rats after myocardial infarction partly by regulating the PKD 1-HDAC5-VEGF signaling pathway.

ObjectiveTo investigate the value of 99Tcm labeled survivin mRNA antisense peptide nucleic acid (PNA) as an imaging agent in the specific diagnosis for carcinoma.MethodsSurvivin mRNA antisense PNA was labeled directly with 99Tcm by the ligand-exchange method.Twenty nude mice with lung carcinoma A549 xenografts were randomly divided into 4 groups.Three groups were used for biodistribution study and one group was used for imaging study.Other twenty mice infected by staphylococcus aureus underwent the same procedure.The biodistribution and imaging of 99Tcm-survivin mRNA antisense PNA was studied at 1,2 and 4 h respectively after the intravenous injection in nude mice bearing lung carcinoma A549 xenografts or inflammation models.SPSS 13.0 was used in the study and all data were analyzed by t test.ResultsBiodistribution results showed that the highest radioactivity was found in the liver,and then in the kidney.Four hours after the administration of the imaging agent,the radioactivity ratios of target-tonon target (T/NT,tumor or inflamumatory lesions to the contralateral regions) in tumor model group were significantly higher than those in inflammation model group ( 3.69 ± 1.13 vs 2.03 ± 0.47,t =3.01,P =0.02 ).Tumors were clearly visible in the tumor model groups at 0.5 h and still clearly seen at 4 h after the injection of antisense PNA.On the contrary,inflammatory lesions could not be seen clearly.Conclusion 99Tcm labeled survivin mRNA antisense PNA can be used to distinguish tumor from inflammation and it may provide a new feasible method for specific tumor diagnosis.
