DNA vaccine is used in infectious diseases initially, and later is applied in neoplastic diseases, allergic diseases and other fields with the further understanding of DNA vaccine and the development of genetic engineering. DNA vaccine transfers the genes encoding exogenous antigens to plasmid vector and then is introduced into organism. It controls the antigen proteins synthesis, thus induces specific humoral and cellular immune responses. So it has a broad application prospect in allergic diseases. Compared with the traditional protein vaccines used in specific immunotherapy, DNA vaccine has many advantages, including high purity and specificity, and improvement of patients' compliance etc. However, there are still two unsolved problems. First, the transfection rate of unmodified naked DNA plasmid is not high, Second, it's difficult to induce ideal immune response. In this study, we will review the progress of DNA vaccine applications in respiratory allergic diseases and its various optimization strategies.

Objective To evaluate the efficacy and safety of proton pump inhibitor (PPI)plus prokinetic drug on the treatment of laryngopharyngeal reflex .Methods According to predetermined criteria of inclusion and exclu-sion ,Cochrane Central Register of Controlled Trails(CENTRAL) ,Embase ,Elsevier ,Pubmed ,VIP ,Wanfang Data , CNKI and CBM were searched for the randomized controlled trails of proton pump inhibitor and prokinetic drug on the treatment of laryngopharyngeal reflex diseases from the date of establishment of the datebases to November 2012 .Revman 5 .1 software and GRAED profiler 3 .6 software were applied to analysis the data ,which was extrac-ted by three independent evaluators .Results A total of 346 related articles were obtained ,7 trails were included , 614 patients in total .The results of Meta -analysis showed that :the overall effictive rate of combination therapy with proton pump inhibitors plus prokinetic drug in patients with laryngopharyngeal reflex was higher than those in the control group [RR=1 .18 ,95% CI(1 .10 ,1 .28) ,P<0 .0001] .The rate of improvement of laryngeal signs exam-ined by fiberoptic laryngoscope was higher than those in the control group [RR= 1 .38 ,95% CI(1 .16 ,1 .65) ,P<0 .001] .The average relief time of dysphonia symptoms was shorter than those in the control group [MD = -1 .70 , 95 CI (-2 .95 ,-0 .45) ,P<0 .001] .Conclusion The effect of proton pump inhibitor plus prokinetic drug on the treatment of laryngopharyngeal reflex is superior to those of proton pump inhibitors or prokinetic drug only ,but in terms of safety ,more large-sample ,high-quality randomized controlled trails are required .

PURPOSE: Anaplastic large cell lymphoma (ALCL) is a rare aggresive non-Hodgkin lymphoma, of which over 50% of cases have an aberrant nucleophosmin (NPM)‒anaplastic lymphoma kinase (ALK) fusion protein. Both mechanistic target of rapamycin (mTOR) inhibitor everolimus and ALK inhibitor crizotinib have shown promising antitumor activity in ALK-positive cancer cell lines. However, their combined effect has not yet been investigated. MATERIALS AND METHODS: We evaluated the anti-proliferative effects of everolimus and/or crizotinib in ALK-positive ALCL cell lines, Karpas 299 and SU-DHL-1, and lung adenocarcinoma cell line, NCI-H2228. RESULTS: We found that individually, both everolimus and crizotinib potently inhibited cell growth in a dose-dependent manner in both Karpas 299 and SU-DHL-1 cells. A combination of these agents synergistically inhibited proliferation in the two cell lines. Crizotinib down-regulated aberrant AKT and ERK phosphorylation induced by everolimus. Combination treatment also significantly increased G0/G1 cell-cycle arrest, DNA damage, and apoptosis compared with everolimus or crizotinib alone in ALK-positive ALCL cells. In the Karpas 299 xenograft model, the combination treatment exerted a stronger antitumor effect than monotherapies, without significant change in body weight. The synergistic effect of everolimus and crizotinib was also reproduced in the ALK-positive lung adenocarcinoma cell line NCI-H2228. The combination treatment abrogated phosphoinositide 3-kinase/AKT and mTOR signaling pathways with little effect on the Ras/ERK pathway in NCI-H2228 cells. CONCLUSION: Crizotinib combinedwith everolimus synergistically inhibits proliferation of ALK-positive ALCL cells. Our results suggest that this novel combination is worthy of further clinical development in patients with ALK-positive ALCL.

Allergic rhinitis (AR) is a global health problem that causes major illnesses and disabilities worldwide. Epidemiologic studies have demonstrated that the prevalence of AR has increased progressively over the last few decades in more developed countries and currently affects up to 40% of the population worldwide. Likewise, a rising trend of AR has also been observed over the last 2–3 decades in developing countries including China, with the prevalence of AR varying widely in these countries. A survey of self-reported AR over a 6-year period in the general Chinese adult population reported that the standardized prevalence of adult AR increased from 11.1% in 2005 to 17.6% in 2011. An increasing number of original articles and imporclinical trials on the epidemiology, pathophysiologic mechanisms, diagnosis, management and comorbidities of AR in Chinese subjects have been published in international peer-reviewed journals over the past 2 decades, and substantially added to our understanding of this disease as a global problem. Although guidelines for the diagnosis and treatment of AR in Chinese subjects have also been published, they have not been translated into English and therefore not generally accessible for reference to non-Chinese speaking international medical communities. Moreover, methods for the diagnosis and treatment of AR in China have not been standardized entirely and some patients are still treated according to regional preferences. Thus, the present guidelines have been developed by the Chinese Society of Allergy to be accessible to both national and international medical communities involved in the management of AR patients. These guidelines have been prepared in line with existing international guidelines to provide evidence-based recommendations for the diagnosis and management of AR in China.

【Objective】 To study the therapeutic effect of autologous platelet-rich plasma(PRP) on joint injury. 【Methods】 Selected patients with joint injury treated in the Department of Transfusion Medicine of General Hospital of Southern Theatre Command of PLA from 2019 to 2020 were enrolled as the research objects, including 5 patients with shoulder joint injury, 34 patients with knee joint injury and 9 patients with ankle joint injury. All patients were treated with PRP injection at the injury site. The functional score and VAS score before and after treatment were compared. 【Results】 After 6 months of treatment, the CMS score and VAS of 5 patients with shoulder joint injury after treatment were (83.00±5.39) and (1.60±0.40), better than those before treatment (60.00±7.58)and (4.20±0.49)(P<0.05); The Lysholm knee score and VAS of 34 patients with knee joint injury after treatment were (80.73±2.43) and (2.07±0.24), better than those before treatment(50.30±2.96) and (4.28±0.33) (P<0.05); The AOFAS Ankle Hindfoot Scale and VAS of 9 patients with ankle joint injury after treatment were (68.44±4.59) and (2.56±0.53), better than those before treatment (42.67±4.57) and (4.89±0.63) (P<0.05). 【Conclusion】 For common joint injury sites, the clinical effect of using PRP injection is significant, which can effectively relieve pain and improve motor function, which is worthy of clinical application.
