As an efficient gene transfer vehicle lentiviral vector has been widely used in therapy research. Comparing with other retrovirus vectors, lentiviral vectors have the unique ablility of transfecting nondividing cells and terminal differentiated cells. In addition, lentiviral vectors can accommodate two or more promoters and can carry larger foreign gene insertions. Now the new generation of lentiviral vectors encoding transcriptional control sequence provides effective means for the regulation of foreign gene expression. The development of lentiviral vectors and its application in the gene therapy field were summarized.

Background Graves ophthalmopathy is generally considered to be an organ-speeifie autoimmune disease.It was reported that 99Tc-methylenediphosphonate (99Tc-M)P) has therapeutic effect on Graves ophthalmopathy,though the mechanism has not been completely delineated.Objective This study was to explore the effects of 99Tc-MDP on the proliferation of retrooeular fihrohlasts (RFs) hyaluronic acid (HA) synthesis,and the expression rate of human leucocyte antigen-DR (HLA-DR) and intercellular adhesion molecule-1 (ICAM-1) in cultured RFs.Methods Retroocular connective tissue was obtained from 2 eyes with Graves ophthalmopathy during the orbital decompression surgery.RFs were cultured with explant culture method in DMEM medium with 20％fetal bovine serum.The cells of 2-7 generations were used in the study.Interferon γ (IEN-γ),interleukin-1 (IL-1),tumor necrosis factor-α (TNF-α) was added in medium for 72 hours to stimulate the growth of the RFs,and then 10,100 and 1000 mg/L 99Tc-MDP was respectively used to co-culture the cells with IFN-γ,IL-1 or TNF-α.3H-TdR incorporation was used to detect the proliferation of RFs,and synthesis of HA,expression rate of HLA-DR and ICAM-1 in RFs were assayed by radio-immunoassay and flow cytometry,respeetively.Results Cultured cells showed the fibrous shape under the inverted microseope with the positive response for vimentin and absent response for cytokeratine.After addition of TNF-α,IFN-γ and IL-1,the proliferation value of RFs,HA level,the expression rate of HLA-DR and ICMA-1 in RFs was (4918.33±297.91) counts/min,(505.83±41.29)mg/L,(56.88±14.67)％ and (63.57± 14.11)％ respectively,showing significant differenee in comparison with normal control group(P＜0.01).However,after co-culture of ＞100 mg/L 99Tc-MDP with TNF-α,IFN-γ and IL-1,the proliferation value of RFs,HA level,the expressing rates of HLA-DR and ICMA-1 were significantly lower than those in the TNF-α,IFN-γ and IL-1 only culture groups(P＜0.01),but were still higher than those in the normal group.Conclusions 99Tc-MDP can suppress cytonike-induced activation and growth of RFs derived from Graves ophthalmopathy in vitro at a dosedependent manner.

Objective:To apply immuno-PCR for detection of anti-Sm antibodies.Methods: Immuno-PCR was established for anti-Sm antibodies in SLE sera using SaHIgG-DNA probe. The experimental conditions were optomized and methological identifieation indicated obvious in crease(×107 ) in sensitivity compared with that of ELISA. The positive rate of anti-Sm antibodies was 54.9% in SLE sera, and significantly higher than that of ELISA. Intra-and inter-CV were 2.3%～4.8% and 3.7%～6.9% respectively. Immuno-PCR was positively correlated with ELISA( p ＜0.001). Therefore, immuno-PCR for anti-Sm antibodies is specific,sensitive,reproducible and practical clinically.

Phospholipid fatty acids are the major constituents of the membranes of all living cells, and different groups of microorganism synthesize a variety of PLFA through various biochemical pathways. Several PLFAs can be used as "signatures" to analyze changes in microbial biomass and microbial communities structure. More and more PLFA method was used in soil microbial analysis. This article briefly reviewed the applications of PLFA methods in soil microbial analysis.

This article was aimed to evaluate the efficacy of acupuncture and flunarizine for migraine treatment. Randomized controlled trials (RCTs) in migraine treatment by acupuncture andflunarizine were searched in the Pubmed, Cochrane Library, CNKI, VIP, and W anfang database. The quality of inclusion criteria were assessedaccording to the CochraneCollaboration's recommended methodand the effective data was extracted. Then, the RevMan5.2 software was used in thesummary and analysis of the effective literatures. The results showed thatthe total sample size was893 cases, with 10 studies according to the inclusion criteria. Meta-analysis showed that the short-term efficacy of the treatment group was higher than the control group [RR = 1.27, 95%CI (1.11, 1.45), P<0.000 4];the long-term efficacy of the treatment group was higher than the control group [RR = 1.76, 95%CI (1.05, 2.94), P=0.03]; headache degree of improvement was better than thecontrol group [MD = -2.00, 95%CI (-3.01, -0.99), P=0.000 1]. It was concluded that acupuncture was more effective than flunarizinein migraine treatment. However, the whole study sample size was relatively small, thequality assessment was not high, and the funnel plot analysis was left-right asymmetry, which indicated the presence of publication bias. It was concluded that more high-quality clinical cases should be confirmed in the future.

The effects of solid-state fermentation (SSF) and submerged fermentation (SmF) and the addition of olive oil on the whole-cell lipase production by Rhizopus chinensis CCTCC M201021 were investigated.Compared with SSF, higher biomass, hydrolytic activity and synthetic activity were observed in SmF.By the addition of olive oil, the synthetic activity of whole-cell lipase in both fermentations was enhanced significantly, especially in SmF, while the biomass and the hydrolytic activity were also increased.Hence, olive oil serves as both carbon source and the inducer of lipases in fermentation.It was also found that the synthetic activity of whole-cell lipase was not accordant to the hydrolytic activity during both SmF and SSF, suggesting that isoenzymes with difference in lipase properties may be produced by Rhizopus chinensis.

Cornea is the major refractive components of the eye. As a viscoelastic tissue, cornea exhibits complicated biomechanical properties: non - linear elasticity, anisotropy and viscoelasticity. The biomechanical properties play an important role in keeping the normal structureand function. Changes in biomechanical properties are always earlier than the clinical symptoms. So quantitative measurement of the biomechanical properties benefits the early diagnosis and treatment of diseases. Different methods to measure the biomechanical properties of cornea were reviewed in detail, including classic ex vivo destructive tests, commercially available in vivo measuring methods and other emerging methods with the potential for clinical application but not validated for in vivo measurement. The operating principles, advantages as well as limitations of these methods were also described.

Objective To explore the effect of minimally invasive surgery in patients with multiple fractured ribs complicated with traumatic diaphragmatic hernia. Methods Clinical data of 48 patients with multiple fractured ribs complicated with traumatic diaphragmatic hernia from January 2010 to January 2016 were retrospective analyzed. All the patients were divided into control group and observation group according to the operation method, 24 cases in each. Patients in control group were treated with thoracotomy, while patients in observation group were treated by video-assisted thoracic surgery. Results The incision length, operative time, blood loss, postoperative thoracic drainage time and hospital stay in the observation group were significantly lower than that in control group, and the difference was statistically significant (P < 0.05). Patients with fractured ribs of the two groups were cured after bandage fixation and the observation group were treated with no conversion to thoracotomy. Clinical efficiency of the two groups were 91.67% and 79.16% and the overall complication rate was 8.32% and 37.48% respectively, the difference is statistically significant (P < 0.05). Conclusion The video-assisted thoracic surgery in treatment of multiple fractured ribs complicated with traumatic diaphragmatic hernia has advantages of less trauma and blood loss during operation, shorter operation time, faster postoperative recovery, and better curative effect, lower incidence of complications. It can be further promoted and used in clinical.
