Objective Varicosis of great saphenous vein has a gradually increased morbidity rate in the troop. We conducted a meta-analysis of the result of two main treatment modalities, namely EVLA (endovenous laser ablation) and HL/ S (high ligation with stripping), in order to provide a better reference for the surgical option. MethodsLiterature published before November 2014 was selected and screened on the basis of inclusion and exclusion criteria for PRISMA statement (preferred reporting items for systematic reviews and meta-analyses), and Epidata (3.1 version) were used for data extraction and RevMan (5.2 version) used for meta-analysis. ResultsA total of seven randomized controlled trials in patients with 1402 cases involving 1455 legs were included in this study. Meta-analysis indicated that: technical success rate was 98.5% and 98.4% for HL/S and EVLA, respectively and OR was 1.06 (95% CI 0.45-2.52), P=0.89; long-term recurrence rate was 15.8% in HL/S and 15.5% in EVLA, OR 1.11 (95% CI 0.18-1.52), P=0.53; long-term reflux rate was 12.5% for HL/S and 15.7% for EVLA, OR 0.65 (95% CI 0.34-1.22), P=0.18. The mean difference of AVVSS (Aberdeen Varicose Vein Symptoms Severity Score) was 0.17 (95% CI -0.63-0.96), P=0.68. ConclusionThere is no significant difference between EVLA and HL/S in the success rate, long-term recurrence rate, long-term reflux rate, and long-term postoperative AVVSS, and both treatment modalities could be the appropriate option for the treatment of varicosity of great saphenous vein.

Objective To investigate the immunogenicity and cross protective effects of two novel HCV DNA vaccines in a mice model.Methods Two self-replicating alphavirus vector-based HCV DNA vaccines, pSCK CE1E2Y and pSCK H155, were constructed based on the genes encoding the structural pro-teins (Core, E1 and E2) and structural and NS3 fusion proteins (Core, E1 , E2 and NS3) of a HCV strain isolated from a Chinese patient (genotype 1b, Hebei strain), respectively.Western blot analysis was per-formed to detect the expression of fusion antigens.The BALB/c mice were intradermally immunized with the recombinant DNA vaccines by using electroporation.The immune responses induced in mice and the cross protective effects of the recombinant DNA vaccines were evaluated.Results The DNA vaccines effectively expressed the target antigens in vitro.The antigen-specific antibody responses and specific T cell immune re-sponses were induced in mice by the immunization of replicative DNA vaccines.However, no effective cross protection was provided by either of the DNA vaccines in the surrogate challenge model based on a recombi-nant heterologous HCV (JFH1, 2a) vaccinia virus strain.Conclusion Although no effective cross protec-tion was observed, both of the two replicative DNA vaccines could induce strong humoral and cellular im-mune responses against multi-target antigens of HCV strains.This study has paved the way for further inves-tigation on the development of novel HCV vaccines.

The T-cell immunoglobulin and immunoreceptor tyrosine-based inhibitory motif domain (TIGIT) is an inhibitory receptor mainly expressed on active T-cells, or natural killer cells (NK cells) that activate negative stimulus signals in immune cells by combining with multiple ligands on the surface of target cells including tumor cells and infected cells. TIGIT plays an important regulatory role in the immune pathogenesis of tumors, viral infections and various autoimmune diseases by inhibiting the over activation of cells and the over secretion of proinflammatory cytokines. Recent researches show that TIGIT is highly expressed in T cells and NK cells of cancer patients, and is related to disease progression and poor clinical prognosis. Researchers try to enhance the activity of T cells or NK cells by blocking the binding of TIGIT and its ligand for therapeutic intervention. At present, there have been many reports about the use of anti-TIGIT monoclonal antibody treatment in different mouse tumor models leading to tumor regression, TIGIT has received extensive attention in cancer immunotherapy as a promising target for next generation cancer immunotherapy. Several clinical trials are currently evaluating the efficacy of anti-TIGIT monoclonal antibodies (mAbs) in patients with several cancers. The most advanced candidate, tiragolumab, has exhibited remarkable efficacy in programmed cell death ligand 1 (PD-L1)-positive non-small cell lung carcinoma (NSCLC) patients in phase Ⅱ clinical trials, in combination with PD-L1 blockade. However, the specific mechanism of TIGIT blockade remains to be fully elucidated.

After 6mo of followed-up, the best corrected visual acuity were all improved in varying degrees (P<0. 05), intraocular foreign body size combined with retinal detachment was the risk factor for visual impact (P<0. 05).
CONCLUSION:Vitrectomy has obvious advantages in the treatment of metal intraocular foreign bodies. Timely and appropriate vitrectomy is very important to the recovery of visual function.

Objective: To understand the prevalence of hepatitis C virus ( HCV ) infection in sentinel surveillance in Liaoning Province from 2015 to 2019, in order to provide evidence for the precise prevention and control of HCV. Methods: The HCV sentinel surveillance data of 5 kinds of populations, including dialyzed patients, patients receiving invasive diagnosis and treatment, family planning outpatients, people receiving physical examination and unpaid blood donators in Liaoning Province from 2015 to 2019 were retrieved, and the HCV positive rates of different years, gender and age groups in the five populations were analyzed. Results: There were 26 000 persons surveyed and 61 HCV positive cases were detected from 2015 to 2019. The HCV positive rate was 0.23%. The HCV positive rates of dialyzed patients, patients receiving invasive diagnosis and treatment, family planning outpatients, people receiving physical examination and unpaid blood donators were 0.40%, 0.70%, 0.25%, 0.24% and 0.14%, respectively. The HCV positive rates of dialyzed patients, patients receiving invasive diagnosis and treatment, and unpaid blood donators had significant downward trends ( P<0.05 ). The HCV positive rates of males and females were 0.22% and 0.26%, without any significant difference ( P>0.05 ). The HCV positive rate of people aged above 70 years old was 1.15%, the highest among different age groups. Conclusions The prevalence of HCV infection among the patients with hemodialysis and with invasive diagnosis and treatment is relatively high. The level of HCV antibody of older age groups should be monitored regularly.

Objective To investigate the development strategy of novel T cell based vaccine against HCV infection.Methods BALB/c mice were primed with pSCK-based DNA vaccine and boosted with type 5 adenoviral vector-based vaccine, which expressed the structural proteins ( Core, E1 and E2) de-rived from a Chinese HCV patient (genotype 1b, Hebei strain).Enzyme linked immunospot assay (ELIS-POT) and intracellular cytokine staining ( ICS) were used to analyze the elicited antigen-specific immune re-sponses and the efficacy of cross-protection.Results Immunization of mice with the prime-boost vaccination strategy elicited stronger T cell immune responses against multiple HCV antigens than using the DNA vac-cines alone, especially the IFN-γ-secreting T cell responses against E1 protein as indicated by ELISPOT as-say.ICS data indicated that the prime-boost regimen elicited more TNF-α-producing CD4+and IFN-γ-produ-cing CD8+T cells against E1 protein and high levels of IFN-γ-producing CD4+and CD8+T cells against E2 protein in comparison with immunization with DNA vaccines.Moreover, the prime-boost vaccination was ca-pable of eliciting effective cross-protection in a surrogate challenge model based on a recombinant heterolo-gous HCV (JFH1, 2a) vaccinia virus.Conclusion The prime-boost vaccination using DNA and rAd5-based vaccine expressing HCV structural antigens induced significant cellular immune response and cross-protection in mice, suggesting the possibility of using it as a promising T cell based vaccine against HCV in-fection.
