Objective:To evaluate the safety and feasibility of the in-situ needle fenestration combined with the in vitro physician modified fenestration technique to reconstruct supra-aortic branches during thoracic endovascular aortic repair (TEVAR) for aortic arch lesions requiring landing at Z0 and Z1.Methods:From Nov 2017 to Dec 2019, eighteen patients who underwent both the in-situ needle fenestration and the in vitro physician modified fenestration techniques to extend the proximal landing zone to Z0 and Z1 during TEVAR were included in our study.Results:Sixteen patients underwent in vitro physician modified fenestration ,two patients underwent in vitro physician modified fenestration to reconstruct both the left common carotid artery and the innominate artery. All eighteen patients received in-situ needle fenestration to preserve the left subclavian artery. Supra aortic branches were preserved in all patients (38/38, 100%). There was no Type Ⅰ endoleak. Type Ⅱ endoleak was found in four paitnets (4/18). Type Ⅲ endoleak occurred in one patient (1/18). Type Ⅳ endoleak in four patients (4/18). Type Ⅲ endoleak needed open aortic arch repair 6 months later. The median follow-up time was 12 months. One (1/18) died in 12 months and the other patients were doing well.Conclusions:The joint application of the in-situ needle fenestration and the in vitro physician modified fenestration to reconstruct supra-aortic branches during TEVAR for aortic arch pathologies requiring landing at Z0 and Z1 was satisfactory.

BACKGROUND: Greatly importance has been attached to ceramic-on-ceramic bearing surface due to its excel ent wear resistance. But the risks of squeaking and ceramic fracture also go with it. Up til now, the choice between ceramic-on-ceramic and ceramic-on-polyethylene bearing surfaces in primary total hip arthroplasty remains controversial. OBJECTIVE: To compare the clinical outcomes and safety between ceramic-on-ceramic versus ceramic-on-polyethylene bearing surfaces in total hip arthroplasty based on meta analysis. METHODS: We electronical y searched databases including PubMed/Medline, Embase, Web of Science, Cochrane Col aboration database, Chinese Biomedical Literature Database (CBMdisc) and China National Knowledge Internet for randomized control ed trials on the comparison between ceramic-on-ceramic versus ceramic-on-polyethylene bearing surfaces in total hip arthroplasty from inception to January 2015. References of the included studies were also retrieved. Investigators severely selected the studies, extracted data and assessed the quality according to the inclusion and exclusion criteria. Then, meta-analysis was performed using RevMan 5.2 software. RESULTS AND CONCLUSION: Nine randomized control ed trials were included, involving 1 231 hips with ceramic-on-ceramic prosthesis and 932 hips with ceramic-on-polyethylene prosthesis. Meta analysis showed that both bearing surfaces achieved satisfied function recovery. But ceramic-on-ceramic had significantly increased risks of squeaking and ceramic fracture, meanwhile ceramic-on-polyethylene showed significantly higher wear rate. There were no significant differences in intra- or post-operative dislocation, osteolysis and other complications and prosthesis failure with any reason between two bearing surfaces. These results suggest that during the short- to mid-term fol ow-up period, no sufficient evidence can tel that ceramic-on-ceramic was obviously super than ceramic-on-polyethylene. Long-term fol ow-up is required for further evaluation.

OBJECTIVETo evaluate the association of cytotoxic T lymphocyte-associated antigen-4 (CTLA-4) + 49A/G polymorphism with type 1 diabetes mellitus (T1DM) in children.

METHODSPapers about the association of CTLA4+49A/G polymorphism with T1DM in children were collected by searching PubMed, EBSCO, CBM, CNKI, and Wanfang Data. A meta-analysis was performed to examine differences in the genotypes (AG, GG, and GG+AG) and G allele at position 49 of the CTLA-4 gene between a childhood T1DM group and a control group.

RESULTSA total of 10 papers involving 1084 T1DM children and 1338 healthy children were included. The Meta-analysis was performed to evaluate the association of the genotypes (AG, GG, and GG+AG) and the G allele at position 49 of the CTLA-4 gene with T1DM using a fixed effect model according to the heterogeneity test results of all studies. The pooled OR values (95% CI) were 1.13 (0.97-1.33), 1.42 (1.16-1.75), 1.20 (1.03-1.40), and 1.21 (1.09-1.33), suggesting a significant difference in genotypes (AG, GG, and GG+AG) and the G allele at position 49 of the CTLA-4 gene between the two groups.

CONCLUSIONSCTLA-4 +49A/G polymorphism is associated with T1DM in children.

OBJECTIVETo investigate magnetic resonance imaging (MRI) characteristics of ovarian carcinosarcoma and the diagnostic value of MRI.

METHODSThe MRI features of ovarian carcinosarcoma and clinical data of 5 patients with ovarian carcinosarcoma were reviewed. All the lesions were confirmed by surgery and pathological examination.

RESULTSMRI of ovarian carcinosarcoma in the 5 cases all showed large tumor mass and heterogeneous high-intensity on T2-weighted images and low-intensity on T1-weighted images, with laminar or stripe-like enhancement. Hemorrhage and necrosis were also displayed in some lesions. In two cases, the tumors invaded the greater omentum, sigmoid colon and the body of the uterus, with regional lymph node involvement. Pelvic effusion was observed in all the cases with pelvic hematocele in 1 case.

CONCLUSIONMRI is useful in the detection and staging of ovarian carcinosarcoma.

OBJECTIVETo investigate the relationship between the stages of calcification of the third molar and age among children in Chengdu.

METHODSThe study subjects consisted of children between 2009 and 2011 at the Department of Orthodontics, West China Hospital of Stomatology, Sichuan University. Panoramic radiographs were obtained. The stages of calcification of the third molar were analyzed by Demirjian's method. The development of the third molar between the male and female was evaluated by independent samples t-test analysis. The Spearman rank correlation was applied to analyze the stages of calcification of the third molar and chronological age.

RESULTSThe development of the third molar of the male was different from that of the female at stage A of calcification of the third molar(P=0.026). The Spearman rank correlation coefficient revealed highly significant relationships between the stages of calcification of the third molar and chronological age of the three groups (male, r=0.808, P=0.000; female, r= 0.729, P=0.000; all, r=0.760, P=0.000). Furthermore, the linear regression equations were established as follows: Yall= 4.898+2.036X: Ymale=4.987+2.046X; Yfemale=4.819+2.036X.

CONCLUSIONThe stages of calcification of the third molar may be an available indicator in judging chronological age of teenager.

Objective: To systemically evaluate clinical efficacy of ivabradine (IVA) treating the patients with chronic heart failure (CHF). Methods: We searched PubMed, Conchrane Library, EMbase, CBM, CNKI and Wanfang database to enroll the random control trials of IVA treating CHF up to 2016-10. Meta-analysis was performed by RevMan 5.2 software. Results: A total of 12 English literature were finally enrolled which including 2 groups: IVA group, n=807 and Control group, n=800. Meta-analysis showed that compared with Control group, IVA group had increased LVEF (MD=2.68, 95％CI 1.85-3.50, P<0.00001), decreased left ventricular end-diastolic volume (MD=-5.78, 95％ CI -9.79 to -1.76, P=0.005), decreased left ventricular end-systolic volume (MD=-8.91, 95％ CI -11.23 to -6.59, P<0.00001) and reduced N-terminal pro-brain natriuretic peptide (MD=-109.22, 95％ CI -126.42 to -92.01, P<0.00001); while systolic blood pressure (MD=6.02, 95％CI -0.80 to 12.84, P=0.08) and diastolic blood pressure (MD=3.6495％ CI -0.48 to 7.77, P=0.08) were similar between 2 groups. Conclusion: IVA improved ventricular remodeling in CHF patients and had no obvious effect on blood pressure. The long-term effect and safety of IVA should be further confirmed by high quality random control trial and the result from evidence-based medicine.

Objective To adopt the expression profile chip to investigate the effect of Rabdosia serra (Maxim.) hara water extract on related gene of human hepatocellular carcinoma(HCC) HepG2 cells for researching the possible mechanism of its water extract on HCC.Methods The human HCC HepG2 cells were cultured in vitro.After adding Rabdosia serra (Maxim.) hara water extract (9.54 mg/mL) for 24 h action,the expression profile chip was adopted to detect the HepG2 gene change after Rabdosia serra (Maxim.) hara action and then the chip results were verified by using RT-PCR and Western blot.Results The phase contrast microscope observation found that compared with the negative control group,the number of HepG2 cells was significantly reduced after Rabdosia serra (Maxim.) hara water extract action.The expression profile results showed that after Rabdosia serra (Maxim.)hara water extract action for 24 h,264 genes were risen to over twice folds compared with the negative control group and 194 genes were decreased by over twice folds compared with the negative control group.The gene ontology(GO) and KEGG analysis indicated that Rabdosia serra (Maxim.) hara could up-regulate multiple genes in DUSPs and IGFBPs family and down-regulate multiple genes in MCMs family.The RT-PCR detection found that compared with the negative control group,DUSP1 and IGFBP1 in the Rabdosia serra (Maxim.) hara treatment group were increased,while FXR and ALDH8A1 were decreased (P＜0.01),which were consistent with the results of expression profile chip.The Western blot results found that the protein expression level of DUSP1 in the Rabdosia serra (Maxim.) hara treatment group was also significantly higher than that in the negative control group (P＜ 0.01).Conclusion The expression profile chip shows that Rabdosia serra (Maxim.) hara can inhibit the proliferation of HCC cells by regulating multiple genes.
