Objective　To develop a new method to induce the gene transfection in high efficiency for eukaryotic cells in vitro. Methods　 Four kinds of p14ARF gene primarily deleted human carcinoma cell line including H460,A549,U251,and PC-3 were transfected with the human p14ARF expression vector (pCI-neo-p14ARF) by using the new nonliposomal transfection reagent Fugene 6. The efficiency of gene transfer was determined by screening the cells in G418. Results　 After 21 days' selection, G418-resistant clones were shown in all the transfected plate. PCR product of p14ARF gene was positive in all the G418-resistant clones. Cytotoxicity of Fugene 6 was detected. The cell proliferation activity was not affected when it was cultured in a high dose of Fugene 6. Conclusion　 These results demonstrate that Fugene 6 is a rapid, feasible, reproducible, and noncytotoxic gene transfection approach for eukaryotic expression vector in vitro.

Objective　To examine whether wild-type p14ARF gene is a candidate suppressor gene for lung cancer. Methods　Human lung cancer cell lines having various endogenous backgrounds in INK4a, p53 and Rb genes were used as the recipients of the wild-type p14ARF gene. The expression of p14ARF mRNA and protein was detected with RT-PCR, immunohistochemistry and Western blot after G418 selection. Clones which expressed both p14ARF mRNA and protein were identified and selected for further experiements. By comparing with the parental and negative control cells treated with empty vectors, the effects of exogenously transfected p14ARF on cell division rate, cell cycle distribution and morphologic alteration were analyzed. In vivo evaluation of the growth rate was also made with the experiment of nude mice tumor formation. Results　Upon transfection with p14ARF gene, cells were arrested at G1 or G1／G2 phase of cell cycle in three wtp53 lung cancer cell lines and their proliferation rates were also inhibited. Conclusion　Human wild-type p14ARF gene has suppressive effect on abnormal proliferation of lung cancer cells, especially in some wtp53 lung cancer cells, and it might be an ideal candidate for gene therapy of human lung cancer.

Objective:To systematically evaluate the therapeutic efficacy of tuina therapy for primary insomnia.Methods:Nine Chinese and English databases were searched from the inception to May 2017 to identify randomized controlled trials (RCTs) studying tuina therapy for insomnia.The enrolled articles were all RCTs with tuina as the monotherapy or major therapy in the experiment group,with clear diagnostic criteria for primary insomnia well recognized worldwide or in China,and Pittsburgh sleep quality index (PSQ I) as one of the outcome measures.Two researchers evaluated the risk of bias and quality of the enrolled studies by following Cochrane Handbook version 5.1.0.The meta-analysis was performed by RevMan version 5.3.Results:Eleven studies were included with a total of 1 076 participants.The Western medication adopted in the control groups were benzodiazepine receptor agonists.The studies were all assessed as high risk of bias for blinding since blinding method was unable to be performed due to the specificity of tuina therapy;no study reported the support of fund or potential interest conflict,so they were all rated unclear for selective reporting.The meta-analysis showed that compared with other traditional Chinese medicine therapies,tuina worked more effectively in reducing the PSQI score (MD=-4.11＜0,95％ confidence interval (CI)-6.01 to-2.22,P＜0.0001);compared with oral administration of Western medication,tuina showed more significant efficacy in reducing the PSQI score (MD=-3.42＜0,95％CI-5.19 to-1.66,P＜0.0001).Subgroup analysis showed that head tuina alone showed no significant difference compared with oral administration of Western medication regarding the change of PSQI score (MD=-4.19＜0,95％CI-8.87 to 0.50,P＞0.05);a combination of head and back tuina could more effectively reduce the PSQI score compared with oral administration of Western medication (MD=-2.08＜0,95％CI-3.09 to-1.06,P＜0.0001).Conclusion:Tuina can produce more significant efficacy in treating primary insomnia compared with other traditional Chinese medicine therapies and oral administration of Western medication,especially the combination of head and back tuina.

AIM: To retrospectively analyze selection of operation, surgery effect, complications and treatment methods of super high myopia combined with rhegmatogenous retinal detachment( RRD) .
METHODS:A total of 47 cases(47 eyes) with the super high myopia patients combined with RRD who accepted scleral buckling of external pressure, vitrectomy combined silicone oil filling, or intravitreous gas injection were chosen in our hospital from Jan. 1, 2011 to Jan. 1, 2016. Best corrected visual acuity ( BCVA), intraocular pressure, retinal reattached rate, closure rate of holes and the postoperative complications of patients in half year were analyzed.
RESULTS:Half a year postoperation, BCVA of twenty-four cases underwent vitrectomy combined silicone oil filling were improving(71%), and eight cases with scleral buckling surgery were enhanced ( 73%) . Statistical test showed the surgical treatment could significantly improve patients'eyesight, especially PPV with silicone oil, but the BCVA of patients with scleral buckling of external pressure in this study had no obvious significance according to the rank sum test. Compare with other surgery, pars plana vitrectomy( PPV ) combined silicone oil filling had more complications, such as high intraocular pressure and diplopia.
CONCLUSION: The therapy of super high myopia patients with rhegmatogenous retinal detachment need many years' clinical experience, surgical skill of clinician and according to the number, the shape and the site of the retinal holes and area of detached retina, they need to choose the right means of surgery, and timely deal with postoperative complications, in order to improve the patients' postoperative retina, reset rate and visual function.

Diabetic retinopathy(DR), one of the most common retinal vascular disease, is one of the causes of blindness for people over the age of 50.In the early stage of DR, microvascular cells are damaged, expand, start to leak, form micro hemangioma, then show occlusion, and non-perfusion area come into being, eventually form new blood vessels because of ischemia and hypoxia of retina.Illness develop into proliferative diabetic retinopathy(PDR).With the aggravation of the disease, PDR can cause the formation of fibrovascular membrane, the more serious fibrillation of epiretinal membrane, resulting in traction retinal detachment(tRD).Present studies suggest that aquaporins, the essential component of new blood vessels, including aquaporin 1 and aquaporin 4, play a significant pole in the development of diabetic retinopathy, causing the destruction of blood retinal barrier, inducing retinal edema, even macular edema, and participating in the formation of retinal angiogenesis.

Myopia is the highest incidence of eye disease in society, it threated people`s eye health seriously.At present, many researchers measure the structural changes of retina which caused by the extension of eye axial due to the refractive error according to the optical coherence tomography(OCT).Besides, multifocal electroretinography(mf-ERG) was used to detect the function of retina in myopia.Global flash mf-ERG can evaluate the function of retina including both outer and inner retina.Some researchers focus on the correlation between structural and functional changes in myopia using OCT and mf-ERG.More researches are needed to clarify the structural and functional changes in myopia.
