Objective To investigate the impact of whole body vibration training combined with intermittent blood flow restriction on the motor function and community activity in elderly stroke patients with hemiplegia.Methods A total of 80 convalescent hemiplegic patients after stroke who were hospitalized in the Rehabilitation Medicine Department of Yichang Central People's Hospital(Xiling Campus)from October 2021 to December 2023 were included and randomly divided into control group(n=25),vibration group(n=28)and combination group(n=27)using the random number table method.All patients received conventional rehabilitation training,on the basis;the vabration group received whole body vibration training,while the combination group received whole body vibration training combined with intermittent blood flow restriction.Before and after 6 weeks of training,the balance function was evaluated with Berg balance scale(BBS),while the gait function was tested with 6-minute walking test(6MWT)and the Community Balance and Mobility scale(CB&M)was used to assess the community activity ability.The community balance and mobility(CB&M)were evaluated in the first and third month after discharge.Results There was no significant difference in BBS,CB&M scores and 6MWT walking distance between the three groups before training(P>0.05).After 6 weeks of training,the three groups showed significant increases in the BBS,CB&Mscores and the walk distance of 6MWT(P<0.001).Furthermore,compared with the control group,the combination group and the vibration group were significantly beter(P<0.05),and there was no signifi-cant difference between the combination group and the vibration group(P>0.05).At the first and third month of follw-up after discharge,the CB&M scores of the three groups were significantly higher than those of the control group(P<0.05),while there was no significant difference between the CB&M scores of the combination group and the vibration group at the first month of follow-up(P>0.05).But the CB&M scores of the combination group was higher than those of the vibration group at the third month of follow-up,and the difference was statistically signifi-cant(P<0.05).Conclusion On the basis of conventional rehabilitation,whole body vibration training combined with intermittent blood flow restriction can significantly enhance balance function,balance confidence,walking ability and mobility in early stage of community life for elderly stroke patients with hemiplegia,potentially facilitat-ing their return to community life.

AIM: To investigate the effects of agkis-trodon halys venom anti-tumor component (AHVAC-) on the biological behavior of gastric cancer MKN-28 cells. METHODS: Gastric cancer MKN-28 cells were treated with the experimental concentrations (5, 10, 15 μg/mL) of AHAVC- for 24 h. Cell proliferation and toxicity assay (cell counting kit-8, CCK-8) was used to detect the inhibition rates of the cells in different concentrations of AHVAC-. The migration ability of the cells was evaluated by wound-healing and Transwell assay. The apoptosis were observed by laser confocal microscopy with annexin V-mCherry/DAPI double staining, and the apoptosis rates were analyzed by flow cytometry with annexin V-FITC/PI double fluorescence staining. The protein level of Caspease-3 was determined by Western blot. RESULTS: Compared with normal control group, the results of AHVAC- concentration groups showed that with the increase of AHVAC- concentration, the proliferative activity of MN-28 cells decreased gradually (P<0.01), the cell migration ability decreased gradually (P<0.01), and the cell apoptosis rate increased (P<0.05). The expression of apoptosis-related protein Caspease-3 was up-regulated (P<0.01). CONCLUSION: AHVAC- inhibits proliferation and migration of gastric cancer MSN-28 cells and induces apoptosis.

OBJECTIVE To investigate the therapeutic effect of natural phenolic compound p-hydroxybenzoic acid(HA) on adjuvant arthritis(AA) induced by the complete Freund's adjuvant(CFA), and to clarify the mechanism of HA preliminary. METHODS Apart from the normal group, all rats received 0.1 mL CFA by plantar subcutaneous injection to induce AA rats model. And rats with AA were randomized to the model group, the low-, medium-, and high-dose HA group(2.5, 5, and 10 mg·kg-1, respectively), the positive control group(indomethacine, 5 mg·kg-1). The rats in each group were orally treated with the corresponding drugs for therapeutic intervention. The volume and leg thickness of the rats in each group were recorded and an inflated articular score was obtained. Inflammation cytokine expression(TNF-α, IL-1β and IL-6) was determined by ELISA and qPCR. Radiographs and HE staining were used to observe histopathological and pathological changes in the foot. The expressions of caspase-1 and NF-κB were examined in Western blotting. RESULTS HA could significantly alleviate joint swelling in AA rat(P<0.05), inhibited the production of inflammatory factors(TNF-α, IL-1β and IL-6) from protein and mRNA levels(P<0.05), and decreased the expression levels of caspase-1 and NF-κB at protein level(P<0.05). HA alleviated ankle injury in rats by X-ray examination, and HE staining showed that HA could significantly inhibit the infiltration of inflammatory cells and the destruction of cartilage surface(P<0.05), and these results were dose-dependent. CONCLUSION HA may relieve rheumatoid arthritis by inhibiting the NF-κB/casepase-1 signaling pathway.

Objective: To evaluate the efficacy and safety of intravascular ultrasound guidance drug-coated balloon (DCB) in percutaneous coronary intervention (PCI) of situ coronary artery lesions in patients with acute coronary syndrome (ACS), and its effect on thrombus precursor protein (TpP). Methods: Seventy-eight patients with ACS in Central Hospital of Changchun City from January 2015 to January 2019 were selected, including 46 cases with unstable angina pectoris and 32 cases with acute non-ST-segment elevation myocardial infarction. The patients were divided into DCB group (38 cases) and drug-eluting stent (DES) group (40 cases) by random digits table method. Intravascular ultrasound was used to guide PCI in both groups, and DCB and DES were used respectively. Coronary angiography was performed immediately and 6 months after PCI in both groups. Minimum lumen diameter (MLD) was measured by QCA system, and the lumen loss (LLL) was calculated at 6 months after PCI. Plasma TpP before PCI, 1 and 6 months after PCI was measured by enzyme-linked immunosorbent assay (ELISA). Major adverse cardiovascular events (MACE) including cardiac death, myocardial infarction and target lesion revascularization (TLR) were followed up 1, 3, 6 and 12 months after PCI. Results: Immediately after PCI, there was no statistical difference in MLD between DCB group and DES group: (1.87 ± 0.23) mm vs. (2.16 ± 0.15) mm, P>0.05; 6 months after PCI, the LLL in DCB group was significantly smaller than that in DES group: (0.31 ± 0.28) mm vs. (0.48 ± 0.19) mm, and there was statistical difference (P<0.05). There were no significant differences in the incidences of myocardial infarction, TLR and cardiac death in DCB group (P>0.05). Before PCI and 6 months after PCI, there was no statistical difference in TpP between 2 groups (P>0.05); 1 month after PCI, the TpP in DCB group was significantly lower than that in DES group: (15.31 ± 6.13) mg/L vs. (19.46 ± 8.24) mg/L, and there was statistical difference (P<0.05). Conclusions DCB is an accurate and effective treatment for ACS patients with situ coronary artery disease under the intravascular ultrasound guidance, and it can reduce the risk of thrombosis.

Objective: To evaluate the effect of intracoronary injection of recombinant human urokinase on plasma P-selectin in AMI patients with no-reflow during acute PCI. Methods: Ninety-two patients with acute ST-segment elevation myocardial infarction or acute non-ST-segment elevation myocardial infarction admitted to Center Hospital of Changchun City in January 2017 and December 2018 were randomly divided into two groups: 47 patients with intracoronary injection of sodium nitroprusside as control group and 45 patients with intracoronary injection of recombinant human urokinase as treatment group. Among them, 58 were males and 36 were females. The onset time was less than 12 h. The basic data, serum P-selectin, myocardial perfusion index and major adverse cardiovascular events were compared between the two groups. Results: In the treatment group, the corrected TIMI frame number, instant TIMI grade 3 blood flow, myocardial chromogenic grade 3 blood flow, myocardial necrosis marker CTnI, serum P-selectin were significantly lower than those in the control group: 31.26 ± 4.58 vs. 35.15 ± 6.25, 71.1%(32/45) vs. 51.1%(24/47), 64.4%(29/45) vs. 55.3%(26/47), (28.46 ± 3.95) ng/ml vs. (30.18 ± 3.47) ng/ml, (13.26 ± 4.58) ng/ml vs. (15.04 ± 3.98) ng/ml, and EF function was better. In the control group. The incidence of major adverse cardiac events in the treatment group was lower than that in the control group within one month after operation, but there was no statistical significance. Conclusions There is no reflux in patients with AMI during PCI. Intracoronary injection of recombinant human urokinase can improve myocardial perfusion without reflux and has no effect on fibrinolytic system in vivo. It does not increase the risk of systemic hemorrhage and the incidence of serious adverse cardiovascular events.

Total 3 483 students in 4 to 9 grade from primary and middle school in Xiling District of Yichang city were selected by stratified cluster random sampling method between September and October 2016 to participate in screening for abnormal angle of trunk rotation(ATR),including 1 797 boys and 1 686 girls aged 9-15 years.The ATR was measured with Scoliometer and the ATR >5°was defined as abnormal.The overall abnormal ATR rate was 7.60%(265/3 483), that in boys was 4.73%(85/1797)and in girls was 10.68%(180/1 686)(χ2=43.75,P<0.05).The abnormal ATR rate in age group 13-15 was higher than that in age group 9-12[10.62%(159/1 496)vs.5.33%(106/1 987),χ2=36.92,P<0.01].Students with low BMI had higher abnormal ATR rate than that with normal or higher BMI(χ2=30.00,P<0.01);and students with left handedness had lower abnormal ATR rate than that with right handedness or double handedness(χ2=6.59,P=0.04).The abnormal ATR rate was not associated with dietary habits or sports in the daily life of students.The results show that gender,age,BMI and handedness affect abnormal rate of ATR.

Background and purpose: AMP-activated protein kinase (AMPK) plays an important role in the regulation of cell metabolism and energy balance and is associated with cell proliferation, survival and multiple signaling pathways. Recent reports found that AMPK is involved in tumor suppression and drug resistance. The aim of this study was to explore the effect of AMPK on the anti-tumor effect of adriamycin and underlying mechanism in breast cancer MCF-7/adr cells. Methods:The anti-proliferative effects of adriamycin was detected by methyl thiazolyl tetrazolium (MTT) assay in MCF-7/adr, MCF-7/adr-vector and MCF-7/adr-AMPKαcells. The cell morphology in each group was stained with the lfuorescent dye Hoechst 33528, and the effects on apoptosis induction were examined by lfow cytometry (FCM). The intracellular concentration of adriamycin was detected by lfuorescence assay. The resis-tance-and apoptosis-related proteins were analyzed by Western blot. Results:The growth of breast cancer MCF-7/adr cells was inhibited by adriamycin in a dose-and time-dependent manner. The IC50 values at 24 and 48 h were (36.8±2.1) and (28.8±1.3) μg/mL, respectively. AMPKαover-expression enhanced the cytotoxic effect of adriamycin in MCF-7/adr-AMPKαcells in a dose-and time-dependent manner. Its IC50 values at 24 and 48 h were (16.0±0.7) and (4.2±0.2) μg/mL, respectively. Fluorescent morphological assay showed that AMPKαoverexpression contributed to adriamycin induced apoptosis in MCF-7/adr-AMPKαcells. After treatment with 1.0 μg/mL adriamycin for 48 h, the apoptosis rates of MCF-7/adr, MCF-7/adr-vector and MCF-7/adr-AMPKα cells were (12.0±1.4)%, (12.7±1.6)% and (32.0±4.2)%, respectively, indicating that overexpression of AMPKα enhanced the adriamycin-induced apoptosis in MCF-7/adr cells. Fluorescence microplate assay showed that over expression of AMPKαsigniifcantly increased the intracellular accumulation of adriamycin, in a concentration dependent manner. Western blot analysis showed that, compared with MCF-7/adr and MCF-7/adr-vector cells, the expressions of Bax, caspase-3 and cleaved PARP proteins were increased. Meanwhile, Bcl-2 and P-gp protein expressions were decreased in MCF-7/adr-AMPKαcells. Furthermore, the release of cytochrome c from mitochondria into the cytosol was also observed in MCF-7/adr-AMPKαcells. Conclusion:AMP-Kαoverexpression can enhance the chemosensitivity of breast cancer MCF-7/adr cells to adriamycin through inhibiting the drug effux transporter and regulating the expression of apoptosis-related proteins.
