Wild-type p53 has been shown to be involved in several aspects of cell growth control. In order to study the role of wild-type p53 in the growth of lung adenocarcinoma cell line GLC-82, recombinant p53 adenovirus vector and the control LacZ gene were constructed. Infection conditions were detected by biochemistry staining for LacZ s expression product ?-gal, immunohistochemical analysis for p53 protein expression, and PCR technique for the infected cells. The cell growth rate and cell cycle were analysed with flow cytometry. The results showed that the constructed recombinant adenovirus vector could infect cells with high level expression of (?-gal and p53 protein and p53 cDNA could be found in the infected cells. The wild-type p53 could inhibit GLC-82 cell proliferation and cause cellular death. These results indicated that wild-type p53 gene mediated by adenovirus vector might be used in the treatment of lung adenocarcinoma.

Background Studies show that retinal neurodegeneration may precede retinal microvascular changes in diabetes mellitus.The apoptosis of retinal ganglion cells (RGCs) is an early finding in retinal neurodegeneration.Toll-like receptor 4 (TLR4) is proved to be up-regulated in diabetic rats retina.However,the impact of TLR4 on RGCs damage in retinal neurodegeneration is poorly understood.Objective The aim of this study was to investigate the expressing change of TLR4 induced by high glucose in RGCs in order to offer a basis for the prevention diabetic retinal neurodegeneration and the study on targeting drugs.Methods RGCs were isolated and purified from the retinas of SPF SD rats aged postnatal 1-3 days by using papain digestion method and then were identified by immunofluorescence technology to detect the expression of Brn3a,a specific marker of RGCs.The cells were divided into normal control group and 10,20,30 mmol/L glucose groups.The expressions of TLR4 mRNA and protein in the ceils were detected by real-time fluorescence quantitative PCR and Western blot analysis in 24 and 48 hours after addtion of glucose.All procedures performed in studies were in accordance with the Association for National Institutes of Health (NIH) Statement for the Care and Use of Laboratory Animals recommendations.The protocol was approved by the Ethics Committee of Renmin Hospital of Wuhan University.Every effort was made to minimize animal discomfort and stress.Results The normal cells grew well with the shape of near roundness after inoculaton.The cells were gradually enlarged and clustered with obvious axons and dendrites 24 hours after purifying.Brn3a showed the positive expression in cultured cells.At 24 hours and 48 hours after glucose culture,the cell structures were gradually invisible in most cells.The expressions of TLR4 mRNA in the cells were 0.945 ±0.237,1.180±0.193 and 0.827±0.213 at 24 hours and 1.509±0.422,2.433±0.617 and 1.435±0.410 at 48 hours after culture in the 10,20 and 30 mmol/L glucose groups,respectively,which were significantly higher than 0.600±0.099 and 0.724±0.302 in the normal control group (all at P＜0.01).The expressions of TLR4 protein in the cells were 0.442±0.147,0.626±0.128 and 0.330±0.153 at 24 hours and 0.464±0.121,0.930±0.441 and 0.394±0.158 at 48 hours after culture in the 10,20 and 30 mmol/L glucose groups,respectively,which were significantly higher than 0.090±0.050 and 0.094±0.070 in the normal control group (all at P＜0.01).Conclusions A large number of RGCs die in a high-glucose environment in vitro,meanwhile,the expression of TLR4 up-regulates in the cells,indicating that TLR4 maybe participate in the damage of RGCs induced by high glucose.

Objective To investigate the clinical efficacy of postoperative three-dimensional conformal radiotherapy concurrent with paclitaxel +TS-1 chemotherapy in the treatment of advanced gastric carcinoma.Methods A total of 60 patients with advanced gastric carcinoma were randomly divided into treatment group and control group.In treatment group,30 patients received simultaneous three-dimensional conformal radiations therapy combined with paclitaxel +TS-1 chemotherapy.In control group,30 patients received paclitaxel +TS-1 chemotherapy.The long term survival rate,local recurrence rate and side reactions were observed in two groups.Results The 1,2-year survival rate in treatment group [93.1％ (27/29),75.9 ％ (22/29)] and control group [72.4 ％ (21/29),48.3 ％ (14/29)] had significant difference (P ＜ 0.05).The 1,2-year local recurrence rate in treatment group [6.9％ (2/29),13.8％ (4/29)] and control group [31.0％ (9/29),44.8 ％ (13/29)] had significant difference (P ＜ 0.05 or ＜ 0.01).The side reactions in two groups were mainly manifested as leukopenia,thrombocytopenia,anemia,nausea,vomiting,liver function damage and oral mucositis.The incidence rate of nausea,vomiting in treatment group was significantly higher than that in control group [83.3％ (25/30) vs.53.3％ (16/30)] (P =0.012).Conclusions Postoperative threedimensional conformal radiotherapy concurrent with paclitaxel +TS-1 chemotherapy in the treatment of advanced gastric carcinoma may improve the long-term survival rate,lower local recurrence rate.But the adverse reactions are increased.

BACKGROUND:Researches have found that minocycline plays a neuroprotective effect by inhibiting the microgliacel proliferation and activation and suppressing glial cels to release cytokines and chemokines. OBJECTIVE:To investigate the influence of minocycline on glial cel line derived neurotrophic factor, NTN and gene expression in substantia nigra and corpus striatum in Parkinson’s disease model rats.
METHODS:144 rats were randomly divided into four groups, with 36 rats in each group. In the normal control group, no intervention was given. In the model and experimental groups, 6-hydroxydopamine was injectedin the right substantia nigra pars compacta and ventral tegmental area to establish Parkinson’s disease models. In the sham surgery group, vitamin C was injected in the two points. In the experimental group, after model establishment, rats were intragastricaly given 4.5 g/L minocycline 45 mg/kg. From then on, additional 22.5 mg/kg minocycline was added every 12 hours. The last group was normal control group. Immediately, 12 hours, 1, 7, 14 and 21 days after model induction, SP immunohistochemistry was used to detect the expression of glial cel line derived neurotrophic factor and NTN expression in the substantia nigra and corpus striatum. RT-PCR was used to identify glial cel line derived neurotrophic factor and NTN mRNA expression in the substantia nigra and corpus striatum.
RESULTS AND CONCLUSION:Both in the substantia nigra and corpus striatum, the positive cel number and relative gene expression of glial cel line derived neurotrophic factor and NTN were lower in the model group than in the normalcontrol and sham surgery groups (P< 0.05). Glial cel line derived neurotrophic factor-and NTN-positive cel number and relative expression were higher in the experimental group than in the model group (P< 0.05). These findings suggest that minocyclinecan delay the process of Parkinson’s disease pathogenesis by promoting glial cel line derived neurotrophic factor protein and gene expression.

Objective To compare the efficacy and safety between Chinese generic imatinib (Xinwei(R),Jiansu Hansoh Pharmaceutical Group Co.,Ltd.) versus branded imatinib (Glivec(R),Novartis) in patients with newly-diagnosed chronic myeloid leukemia in chronic phase (CML-CP).Methods Patients with newly diagnosed CML-CP were enrolled and assigned to receive either Xinwei or Glivec at an initial dose of 400 mg/d according to patients' financial capability.The efficacy and adverse effects were evaluated.Results From January 2014 to September 2015,145 eligible patients were assigned to Xinwei (n =89) or Glivec (n =56) group.All patients were treated and followed up at least 3 months.At 3 months,the complete response rates were 95.5％ (85/89) and 100％ (56/56),major cytogenetic response rates were 74.2％ (66/89) and 80.4％ (45/56),and the proportions of achieving BCR-ALBIS ≤ 10％ were 76.1％ (67/88) and 82.1％ (46/56) in Xinwei and Glivec groups respectively (all P ＞0.05).With a median follow-up of 12 months,2 patients in each group progressed to accelerate or blast phase.Hematologic and non-hematologic side effects were similar between the 2 groups.Conclusions Early hematological,cytogenetic and molecular responses between Xinwei and Glivec are comparable in newly-diagnosed CML-CP patients.The progression rate and side effects are also similar between the 2 groups.

Objective To investigate the afflication of non-humidified low flow nasal oxygen inhalation in the ICU patients. Methods Four hundred patients hospitalized in ICU and needing continuous low-flow oxygen inhalation for more than 24 h were randomly divided into experiment group and control group equally.The experiment group were managed with dried humidification bottle oxygen inhalation and the control group conventional humidified bottle oxygen inhalation.The two groups were compared in terms of 24 h respiratory reactions,bacterial contamination of the humidified bottle,complaints of patients about oxygen inhalation noises and time for nurses to change the humidified bottles.Results The two groups had no significant difference in adverse symptoms(all P>0.05).The rate of bacterial contamination in the experimental group was significantly lower than the control group(P<0.05),the noises were lower and the time for changing the bottle shorter(P<0.05).Conclusion Non-humidified low flow nasal oxygen inhalation in ICU patients is good for reducing the rate of bacterial contamination of humidified bottle and lowering workload and oxygen-inhaling noises.
