We used retrovial vector LXSN to construct recombinant retroviral vector with mutant membrane bound TNF - ? gene. The vectors were introduced into packaging cell line, CRIP cells. The G418-resistant colonies were selected and the supernatants of the colonies were used to determine the virus titers. The titer of virus was 1? 104CFU/ml and the retroviral vectors were used to tranduced the human gastric cancer cell line, MGC-803 cells. The results of southern blot assay showed thai the targel gene had integrated into the genomic DNA of MGC-803T. MGC - 803Tcells were ablc to kill L929 cell line, but the parent cell line showed no cytotoxicily to the cells at all. There was no any variance in the morphological appearance and growlh rate in vilro of MGC-803N and MGC-803T cells. The results of inoculation in nude mice with these cells indicated that MGC-803T cells showed a considerable decrease in size of tumor. These results suggested that the retroviral vectors expressing mulant TNF -? gene were successfully construed. MGC - 803T cells showed cytotoxicily slrongly lo L929 cell line in vilro and lumorigenicity .

Neovascular glaucoma ( NVG ) is a series of blinding and intractable eye diseases, which caused by various intraocular or extraocular diseases. The iris and angle neovascularization and vascular membrane fiber contraction may eventually lead to progressive elevation of intraocular pressure and angle closure. Because of complex etiology, the treatment of NVG is intractable and inefficient. Based on the articles published in recent years, we reviewed the progressions of the relevant cytokines and animal models.

Objective To observe the effect of simvastatin on intimal proliferation in abdominal aorta of rabbits after stenting.Methods Thirty male New Zealand white rabbits were allocated into two groups including the control group(n=15)and the treatment group(n=15).All the rabbits were fed on 1.5% high cholesterol diet and underwent ballon injury of abdominal aorta from femoral approach and stents were implanted in the segments with stenosis rate greater than 50%.Rabbits in the treatment group were given simvastatin 5 mg/d after stenting.Neointima proliferation of the stented segments was examined on the 30th day after stenting by histological staining and the expression of P27kip1 and PCNA in each group was also analyzed.Results Histological staining showed that on the 30th day after stenting,the thickness of vessel wall(0.107?0.072 mm vs 0.133?0.047 mm,P=0.006)and the area of neointima(0.975?0.084 mm2 vs 1.350?0.043 mm2,P=0.001)were less in the simvastatin treatment group compared with the control and the rate of lumen loss was less than that of the control(20.460%?2.325% vs 31.020%?1.904%,P=0.002).The expression of P27kip1 in the neointima VSMC cell nuclear was higher(7.149?0.305 vs 2.997?0.310,t=9.551,P

Objective To explore the association between Q-1 and T1 locus polymorphism in ADAM33 gene and chronic obstructive pulmonary disease in Han population in northern Guizhou by detecting Q-1 and T1 locus polymorphism in ADAM33 gene in patients with COPD in the distribution of frequency ,provide a theoretical basis for the prevention and treatment of COPD. Methods Polymerase chain reaction and DNA sequencing tech-nology,electrophoresis separation method were applied to detect Q-1 and T1 locus polymorphism in ADAM33 gene. Results The genotype distribution of Q-1 and T1 locus in the case group and the control group of ADAM33 gene were in accordance with the Hardy-Weinberg equilibrium law and ADAM33 gene Q-1,T1 locus were C and T alleles. There was no significant difference in genotype and allele frequency distribution between the case group with control group,and COPD complicated with chronic respiratory failure(COPD)and hypoxemia(P > 0.05). T1(83 bp,112 bp)at a high probability of two heterozygous in the same samples(18/19),and is located in the encoding region. Conclusion No association was found between Q-1,T1 locus polymorphism in ADAM33 gene and chronic obstructive pulmonary disease in Han population in northern Guizhou.

Objective To analyze morbidity,mortality and epidemiological characteristics of epidemic encephalitis B (Japanese encephalitis) from 2002 to 2013 in Zunyi.Methods The descriptive and statistical analysis of the incidence and death of epidemic encephalitis B from 2002 to 2013 in Zunyi was carried out.Results The morbidity and mortality were on a downward trend of epidemic encephalitis B in Zunyi from 2002 to 2013;most of the death and incidence cases occurred in July and August from children living scattered and students under age 15;after immunization expansion,the incidence of encephalitis B showed significant differences between ages,occupations,and time points (P<0.05);in the regional distribution of epidemic encephalitis B,incidence and mortality had significant differences (P<0.05).Conclusion Promising results might be generally obtained after expansion of encephalitis B immunization.However,there is a tendency of shifting back in terms of onset age and month.Therefore,comprehensive prevention measures should be implemented according to the epidemiological features of epidemic encephalitis B.

The therapeutic effects and mechanisms of traditional Chinese kidney-tonifying drugs in treating osteoporosis have become the focus under study. Pharmacological studies have shown that traditional Chinese kidney-tonifying drugs are promoters for the proliferation of osteoblasts, inhibitors for the activity of osteoclasts, regulators for the estrogen level and its receptor, plays important roles in promoting osteogenesis and suppressing adipogenesis of marrow mesenchymal stem cells (MSCs), modulating the function of OPG/RANK/RANKL system and the metabolism of calcium and phosphorus, as well as antioxidation. The anti-osteoporotic active ingredients and pharmacological action mechanism of traditional Chinese kidney-tonifying drugs are summarized from the perspective of molecular and cell biology in this paper, so as to provide references for the study of their mechanism of anti-osteoporosis and for the development of traditional Chinese kidney-tonifying and bone-strengthening drugs.

Objective To analyze the curative effect of super-early keyhole surgery in treatment of hypertensive cerebral hemorrhage. Methods Clinical data of patients with hypertensive cerebral hemorrhage who received treatment in our hospital from April 2010 to October 2012 were retrospectively analyzed. Patients were divided into the observation group ( keyhole surgery group) and the control group ( routine group) by different therapeutic methods. The operation time, rate of hematoma clearance, postoperative complications, and recovery of neu-ral function of the two groups were compared. Results The observation group had a shorter operation time than the control group, and the difference was statistically significant(P<0. 001). There was no singnificant difference between the two groups in rate of hematoma clear-ance at the time of tube drawing(P>0. 05). The observation group had less postoperative complications than the control group, and the difference was statistically significant(P<0. 05). The observation group had a lower rate of metabolic disorders than the control group with a statistically significant difference(P<0. 05). Patients of the observation group had a higher scores of SSS than patients of the control group 28 days after operation, and the difference was statistically significant(P<0. 05). 6 months after operation, the observation group had a bet-ter ADL than the control group, and the difference was statistically significant(P<0. 05). Conclusion Super-early keyhole surgery which has less intraoperative injury, postoperative complication, and metabolic disorders, can achieve a better effect than routine operation. And it is of better neural functional recovery.
