Objective To evaluate the clinical application effect of fracture liaison service(FLS)mode after percutaneous vertebroplasty(PVP)/percutaneous kyphoplasty(PKP)for thoracolumbar fragility fracture.Methods A prospective study was conducted,and 762 patients with thoracolumbar fragility fracture who underwent PVP/PKP in the department of orthopedics in our hospital from January 2018 to May 2021 were included and divided into the control group(374 cases)and the observation group(388 cases)according to the random number table method.Patients in the control group received routine osteoporosis intervention,while the patients in the observation group implemented FLS through Blue Bull Medical Care or Chronic Health APP on the basis of the control group to systematically manage the osteoporosis treatment after discharge.The follow-up lasted for 12 months,and the 8-item Morisky medication adherence scale(MMAS-8)score,pain visual analogue scale(VAS)score,Oswestry disability index(ODI)score and Hamilton depression rating scale(HAMD)score at discharge,and 6 months and 12 months after discharge of the two groups were compared.The incidences of re-fracture and constipation 6 months and 12 months after discharge of the two groups were compared.The Cobb angle and bone mineral density T-value of injured vertebrae 6 months and 12 months after discharge of the two groups were compared.Results There was no statistically significant difference in the MMAS-8 score,VAS score,ODI score or HAMD score at discharge of patients between the two groups(P>0.05).The VAS score,ODI score and HAMD score 6 months and 12 months after discharge in the observation group were lower than those in the control group(P<0.05),the MMAS-8 score in the observation group was higher than that in the control group(P<0.05),and the incidences of re-fracture and constipation in the observation group were lower than those in the control group(P<0.05).There was no statistically significant difference in the Cobb angle of injured vertebrae 12 months after discharge of patients between the two groups(P>0.05).The bone mineral density T-value 12 months after discharge in the observation group was higher than that in the control group(P<0.05).Conclusion The FLS mode can significantly improve the medication compliance of patients,relieve pain,depression and constipation,improve bone mineral density,and significantly reduce the incidence of vertebral re-fracture in patients after vertebral augmentation surgery;however,it has no significant effect on the Cobb angle of injured vertebrae.

Objective:To compare the surgical procedures and postoperative effects of PFNA and DHS in the treatment of intertrochanteric fracture in elderly patients.Methods:The clinical data of 30 elderly patients with intertrochanteric fracture treated in our department from March 2013 to March 2017 were retrospectively analyzed.15 cases were treated with PFNA internal fixation and 15 cases with DHS internal fixation.The average length of operation,the amount of bleeding during operation,the time of hospitalization and the difference of postoperative functional recovery were compared between the two surgical procedures.Results:The intraoperative bleeding of the DHS group was more than that of the PFNA group,and the difference was statistically significant (P＜0.05).There was no significant difference in length of operation,time of hospitalization or postoperative hip function between the two groups.Conclusions:DHS is similar in clinical efficacy to PFNA in the treatment of intertrochanteric fracture in elderly patients,especially for intertrochanteric fractures with simple fracture types and intact lateral wall of the femur.DHS has the advantages of anatomical reduction and simple operation,which is worthy of clinical promotion.

To evaluate the efficacy of changing grains on the prevention and treatment of Kashin-Beck Disease (KBD) in children, community-based trials were acquired from seven electronic databases (up to July 2014). As a result, the methodological quality of the six trials that have been included into our analysis was low. The pooled ORs favoring the prevention and treatment effects of changing grains were 0.15 (95% CI: 0.03-0.70) and 2.13 (95% CI: 1.44-3.16) respectively by meta-analysis. Subgroup analysis demonstrated the pooled OR favoring treatment effect of exchanging grains rather than drying grains both compared with endemic grains. The results showed that changing grains had obvious effects on the prevention and treatment of KBD in children. However, the evidences were limited by the potential biases and confounders. Large and well-designed trials are still needed.

Fragments encoding amino acids 76-130 in the linear conserved region (LCR) of A/Hubei/1/2010 (H5N1) HA2 was fused to hepatitis B core antigen (HBc) to generate a LCR-HBe virus-like particle (VLP). Results showed that the fusion protein of LCR-HBc was highly expressed in this prokaryotic expression system. The purified LCR-HBc particle stimulated high levels of IgG production in mice with a titer of > 1:12 800, and provided 50% cross-protection against lethal challenge by H1N1 viruses.

BACKGROUNDAndrographolide has been shown to have anticancer activity on diverse cancer cell lines representing different types of human cancers. The aim of this research was to investigate the anticancer and apoptotic effects of andrographolide on the BGC-823 human gastric cancer cell line.

METHODSCell proliferation and IC50 were evaluated using MTT assay, cell-cycle analysis with flow cytometry apoptotic effects with Annexin-V/propidium iodide double-staining assay, and morphologic structure with transmission electron microscopy. Immunohistochemistry and reverse-transcription PCR was used to analyze Bcl-2, Bax, and caspase-3 expressions.

RESULTSAndrographolide showed a time- and concentration-dependent inhibitory effects on BGC-823 cell growth. Compared to controls, the number of cells in the G0-G1-phase increased significantly, S and G2-M-phase cells decreased after 48 hours of treatment with andrographolide, and both early and late apoptotic rates increased significantly compared to the controls, all in a concentration-dependent manner. Bax and caspase-3 expressions were markedly increased, and Bcl-2 expression was decreased.

CONCLUSIONSAndrographolide inhibits BGC-823 cell growth and induces BGC-823 cell apoptosis by up-regulating Bax and caspase-3 expressions and down-regulating Bcl-2 expression. Andrographolide may be useful as a potent and selective agent in the treatment of human gastric cancers.

Objective To investigate the impact of cytochrome P450 (CYP) 2C19 681G>A polymorphism on long-term prognosis of clopidogrel-treated Chinese patients after percutaneous coronary intervention (PCI).Methods Between January 1, 2009 and August 31,2009, 267 patients with coronary heart disease who received PCI and treated with clopidogrel for 12 months were enrolled. CYP2C19*2 was detected by MALDI-TOF MS and patients were grouped into CYP2C19*1/*1(n=130) and CYP2C19*2 carriers group (n=137). Follow-up was 12 months. The primary endpoint was angina recurrence, urgent coronary revascularization, acute myocardial infarction, stent thrombosis, death and the combined end points. Results Baseline data were similar between two groups (P>0.05).Urgent coronary revascularization and the combined end points occurred more frequently in CYP2C19*2 carriers than in CYP2C19*1/*1 patients (7.3% vs. 1.5% and 8.0% vs. 2.3% respectively,all P<0.05). But incidence of angina recurrence, acute myocardial infarction, stent thrombosis and death was similar between two groups (all P>0.05).Hazard risk of 1 year cumulative survival of CYP2C19*2 carriers group was significantly higher than CYP2C19*1/*1 group after PCI (HR=3.59, 95%CI: 1.02-12.87, P<0.05). Conclusion CYP2C19 681G>A polymorphism is a determinant of prognosis in coronary heart disease patients receiving chronic clopidogrel treatment after PCI.

OBJECTIVETo evaluate the clinical significance of 320-slice CT hepatic artery images in patients with liver transplantation.

METHODSA total of 58 patients underwent CT scanning by 320-slice scanner after liver transplantation. They were divided into 2 groups according to the concentration of contrast media as follows: Group A (27 cases, 350 mgI/ml iopromide), Group B (31 cases, 370 mgI/ml iopromide). Contrast medium was infused at 6 ml/s, with a total dose of 50 ml. Images were generated by dynamic volume scanning and were processed by 4D digital subtraction angiography (DSA) imaging software. The time-density curve (TDC) of the hepatic artery was delineated. The time to peak, peak contrast enhancement were recorded. The physiological parameters such as body weight and height were analyzed.

RESULTS(1) There were no differences in clinical parameters such as age, sex, height, weight, or BMI between groups. The time to peak of hepatic artery of group A and B was (19.71+/-3.11) s and (20.06+/-3.67) s, and had no significant difference. The maximum peak enhancement of hepatic artery in groups B was higher than that group A (P < 0.05). (2) 4D DSA revealed hepatic artery pseudo-aneurysm (n = 2), and hepatic artery mild stenosis (n = 13), moderate stenosis (n = 5), severe stenosis (n = 9) and occlusion (n = 1), segmental moderate and severe stenosis (n = 4), and compensatory circulation with hepatic artery severe stenosis and occlusion (n = 6). hepatoportal arteriovenous fistulas (HPAVF, n = 12), donor-recipient hepatic artery mismatch (n = 3). Hepatic arterial branch are decreased and opened in 15 cases and 8 cases.

CONCLUSION320-slice CT hepatic artery images is safe, noninvasive, and accurate technique to evaluate hepatic arterial complications after liver transplantation.
