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.

BACKGROUND:Bone tissue transplantation or osteogenic material fil ing is after used for bone defect repair. To remove autologous bone tissues can lead to additional damage and secondary deformity, therefore, it is extremely urgent to search for a new osteogenic material. OBJECTIVE:To construct the porousβ-tricalcium phosphate (β-TCP)/col agen scaffold modified with human bone morphogenetic protein 2 (hBMP2) gene, and to observe its effects on differentiation of MC3T3-E1 cel lines. METHODS:The porousβ-TCP/col agen scaffold modified with hBMP2 gene was prepared. Then in vitro culture system of MC3T3-E1 cel lines with composite scaffold was established. There were scaffold and plate groups, and each group was divided into two subgroups according to the different concentrations of plasmid. Samples were col ected and observed morphological y by scanning electron microscope and light microscope after complex culture. After 1, 3, 7 and 14 days of induction, calcium nodules were observed through alizarin red staining, the cel cycle was detected by real-time PCR, and expressions ofαI-chain col agen type I gene, Osterix and bone sialoprotein were observed. RESULTS AND CONCLUSION:The number of cel s adhered, differentated and distributed on the composite scaffold was significantly higher than that of the single scaffold (P<0.05). Alizarin red staining and real-time PCR detection showed that the osteogenesis ability of MC3T3-E1 cel lines in the scaffold group was stronger than that in the plate group. To conclude, the porousβ-TCP/col agen scaffold modified with hBMP2 gene is an appropriate candidate for bone defect repair.

Objective To investigate the effect of vascular tortuosity and bending radius on the new type knitting stents (LVIS stent ) releasing on the cavernous sinus segment of internal carotid artery. Methods From December 2015 to January 2016,31 consecutive patients with wide-neckedaneurysm treated with LVIS stents and the proximal end of the stent released in the cavernous segment at the Department of Neurosurgery,Changhai Hospital,the Second Military Medical University were enrolled. According to whether the stents completely adhered to the walls or not after the first release,they were divided into two groups:a satisfactorily release group (n =23 )or an unsatisfactorily release group (n =8 ). The differences of vascular tortuosity and bending radius of the 2 groups were compared.Results Thevascular tortuosities of the satisfactorily release group and the unsatisfactorily release group were 118° ± 23° and 147° ± 19° respectively. There was significant difference (P=0. 028). The vascular bending radii were 3. 4 ± 0. 7 mm and 2. 8 ± 0. 7 mm respectively. There was significant difference (P=0. 042). The mean vascular tortuosity was larger and the mean vascular bending radius was smaller in the unsatisfactorily release group. Conclusions The greater the vascular tortuosity,the smaller the vascular bending radius may be connected with the unsatisfactorily release in the LVIS stent. The evaluation of vascular tortuosity is conductive to the guidance of the stent release technique before stent implantation.

Authors described the patterns,core measures and mechanisms of coordinated care delivery in the localities and analyzed initial outcomes of this practice.It is found that such practice has optimized distribution of regional healthcare resources,implemented first visit to primary institutions, and the care delivery to separate emergency from outpatient service.In addition,the paper analyzed problems found in localities in terms of policy,public hospitals and primary institutions,and proposed elements required for coordinated care delivery system to succeed,such as enhanced policy support, enhanced multi-departmental coordination,and public hospital reform to explore feasible approaches.

Objective To establish a three- dimensional hindlimb gait data toolkit (THGT) for healthy and spinal cord injured (SCI) non-human primate (rhesus monkey) based on Matlab to realize upload of original data, automatic gait division, calculation and drawing of multiple gait parameters, etc. Methods Vicon system was used to collect three-dimensional hindlimb gait data of healthy and SCI (after 6 weeks) rhesus monkey to obtain the kinematics data of both hindlimbs in continuous strides. It was analyzed with THGT to process the gait division, calculation and drawing of multiple gait parameters. Results THGT read the data, distinguished cycles of gait, calculated 140 kinds of gait parameters and drew graphs of the results. Conclusion THGT extends the universality of the Vicon data, realizes automatically gait division and friendly interactive interface, and puts out the visible results.

OBJECTIVETo study the radiosensitizing effect of resveratrol on hypopharyngeal carcinoma cell line FADU in vitro.
METHODSHypopharyngeal carcinoma cell line FADU was cultured in in vitro DMEM. Its inhibition on cell proliferation was detected using cytotoxicity test (MTT assay). The cell survival curve was drawn using clone formation to obtain sensitive enhancement ratio (SER). Changes of the cell cycle and cell apoptosis were analyzed using flow cytometry (FCM).
RESULTSResults of MTT showed the inhibition of resveratrol on FADU cells increased along with its concentrations (P < 0.05). Results of clone formation indicated the surviving fraction at 2 Gy (SF2) was 0.717 ± 0.062 in the irradiation group, and 0.426 ± 0.035 in the resveratrol plus irradiation group (with SER ranged 1.684 ± 0.178) with statistical difference (P = 0.007). Results of FCM showed that after radiation of 4 Gy radiation, cells at G2/M phase arrest increased, but cells at G1 decreased. After radiation of resveratrol for 24 h, cells at G1 decreased, but cells at G2/M phase and S phase arrest increased. When 4 Gy radiation combined resveratrol was used, cells at G2/M phase arrest significantly increased, but cells at G1 significantly decreased. The apoptosis rate was 1.94% ± 1.65% in the control group, 4.56% ± 0.92% in the irradiation group, 2.03% ± 1.46% in the resveratrol group, and 23.11% ± 7.22% in the resveratrol plus irradiation group. There was statistical difference between the resveratrol plus irradiation group and the rest 3 groups (P < 0.05).
CONCLUSIONResveratrol could enhance the radiosensitivity of hypopharyngeal carcinoma FADU cells in vitro possibly by inducing cell apoptosis and causing changes in the cell cycle distribution.
