Objective To observe the aging,apoptosis,cell cycle arrest and oxidative stress in human skin fibroblast(HSF)induced by UVB,and to detect the expression profiles of p66Shc,a determinant of oxidative stress response and life span,in this process.Methods HSF cells were exposed to UVB at a subcytotoxic dosage twice a day for three days.The cells without exposure served as control.After another 24-hour culture,SA-β-Gal staining was performed to evaluate the senescence state of the cells,flow cytometry to observe cell apoptosis;cell cycle arrest was detected by serum starvation and flow cytometry:ELISA was applied to detect intracellular levels of superoxide dismutase(SOD)and malondialdehvde(MDA),and Western blotting to analyze the expression of p66Shc protein.Results The percentage of cells positive for SA-β-Gal staining increased from 0 to 98.3% after UVB radiation,which strongly suggested an aging state of HSF cells.The percentage of apoptotic cells increased from 0.96% to 37%.and 80.07% of the HSF cells were arrested in G0/G1 phase following the irradiation.Intracellular SOD activity decreased from(52.35±4.97)ng/g to(7.81±0.68)ng/g(P<0.01).while intracellular MDA was found to increase from(3.52±0.34)ng/g to(33.91±3.20)ng/g(P<0.05).The p66Shc protein was found to be weakly expressed in HSF in 24 hours following the exposure to UVB,and a stronger expression was noted 48 hours later.Conclusions HSF cells are induced into a state of senescence associated with oxidative stress after UVB irradiation,which may be applied as an in vitro model in aging research.The expression of p66Shc is increased in HSF during this process,and further studies are needed to explore the relation between p66Shc and oxidative stress as well as cellular aging.

AIM To study the protective effects of Jingqi Capsules (Cordycps Militaris,Rehmanniae Radix Praeparata,Lycii Fructus,) on the damage to rat reproductive system induced by cyclophosphamide.METHODS After low and high dose groups of Jingqi Capsules and positive group were administered for two weeks in advance,cyclophosphamide [25 mg/(kg · d)] modeling was conducted consecutively by intraperitoneal injection for five days except the normal group,while the treatment groups were administered consecutively.All the rats were executed the day after the end of the modeling.Serum testosterone content was measured by radioimmunoassay;body weight,testis,epididymis and prostate of rats were weighed and organ coefficient was calculated;morphology of testis was observed by HE;sperm count and sperm motility were detected by CASA;apoptosis of cells was observed by TUNEL.RESULTS Compared with the model group,each dose group of Jingqi Capsules increased in the level of serum testosterone and organ coefficient of testis,epididymis and prostate.The damage to seminiferous epithelium relieved and the number of all spermatogenic cells increased.Sperm count and sperm motility increased.Decrease in apoptosis of cells was demonstrated by TUNEL.CONCLUSION Jingqi Capsules has protective effects on damage to rat reproductive system induced by cyclophosphamide.

AIM: To investigate the effects of goat placenta immunoregulating factor(GPIF) on the expression of costimulatory molecules lineaged T cells in BALB/c mice.METHODS: Animal model for immunodeficiency made from BALB/c mice with whole-body irradiation by 5 Gy 60Co?-ray was applied for research.The immunosuppressive mice were injected with GPIF for seven days continuously.FACS was applied to analyze the rate of CD28+,CD152+,CD4+CD28+,CD8+CD28+,CD4+CD152+ and CD8+CD152+ cells in splenic lymphocytes and ELISA method was employed to measure the amount of IL-2 and IFN-? in serum of mice.RESULTS: GPIF increased the percentage of CD28+,CD4+CD28+ and CD8+CD28+ cells(P

In both type 1 and type 2 diabetes mellitus,β-cell mass (BCM) is lost.Various treatments are developed to restore or reconstruct BCM.The development of non-invasive methods to quantify BCM in vivo offers the potential for early detection of β-cell dysfunction prior to the clinical onset of diabetes.PET imaging with radioligands that directly target the pancreatic β-cells appears promising.The ability to determine the BCM has been investigated in several targets and their corresponding radiotracers,including radiolabeled receptor ligands,antibodies,metabolites and reporter genes.Therefore,we summarize the recent progress in radionuclide molecular imaging of pancreatic β-cells.

Objective To investigate the role of inhaled corticosteroids (ICS) on transforming growth factor - ?1 (TGF - ?1 )of asthmatic remodeling model Methods One hundred and eight guinea pigs were divided into 3 groups randomly and equally: asthmatic group( A), therapeutic group(B), control group(C) Three groups were treated by ovalbumin, budesonide, normal saline respectively The lung tissue specimens were collected after the guinea pigs were killed; the expression of TGF- ?1 was determined Results The expressions of TGF-?1 in A, K and C groups were(41 83 ? 10. 45) %, (27. 22 ? 8. 09)% , (15. 36 ? 2. 64)% respectively at 12 weeks.

Background Some researching results of sodium hyaluronate eye drops treating dry eye have been reported home and abroad.To evaluate these results using the method of evidence-based medicine (EBM) has an important clinical significance.Objective This secondary study was to systematically evaluate the efficacy of sodium hyaluronate eye drops for the treatment of dry eye.Methods Meta analysis was adopted in this study.The electronic bibliographic databases were searched according to the prescribed strategy,including Medline,PubMed,VIP,CBM,CNKI,Wanfang Data using the method of Cochrane systematic review.The literature published time was limited from the commencement of each database to December,2011.Randomized controlled trials (RCTs) of sodium hyaluronate eye drops treating dry eye were included and the methodological quality of the RCTs was assessed by two evaluators using Jadad measuring scale,and homogeneous evaluation by Meta-analysis was performed.Statistical analysis of clinical data was performed using RevMan 5.0 software provided by the Cochrane Collaboration.With odds ratio (OR) value as the effect index,the randomized effect model was used to analyze the clinical heterogeneity.Results A total of 4 RCTs involving 686 patients were included.Jadad scale evaluation showed 7 points in 2 literature,4 points in 1 literature and 2 points in 1 literature.In all the RCTs,344 patients with dry eye were treated using sodium hyaluronate as the sodium hyaluronate eye drops group,and 342 dry eyes applied placebo,normal saline solution,hydroxymethyl cellulose,hydroxypropyl methyl cellulose respectively as the control group.Meta-analysis indicated that the total effective rate (OR) was 2.55 with the 95% confidence interval (CI) 0.94-6.93.The symptoms were improved in 183 cases in the experiment group and 130 cases in the control group.No significant difference was found in the OR between the sodium hyaluronate eye drops group and the control group (Z =1.84,P=0.07).Conclusions Meta-analysis indicates that sodium hyaluronate eye drops can improve the symptom of dry eye,but have no significence with the control group.However,owing to fewer number and uneven quality of included RCTs,the large sample size and multicenter of RCTs is still needed to verify the superiority of sodium hyaluronate eye drops for dry eye.

ObjectiveTo investigate the effort of MHA-bBMP implantation combined with limited contacted titanium net duct fixation on femoral shaft bone defect of rabbit.Methods48 rabbits were divided into the experimental group (treated with bionic bone MHA-bBMP plus titanium net duck) and control group (treated with iliac autograft plus titanium net duct) with 24 animals in each group. The rabbit femoral shaft bone defect model was established by cutting 10 mm bone fragment off. After operation, bionic bone MHA-bBMP/iliac autograft was implanted into bone defect area and fixed with limited contacted titanium net duck. The general condition, serum alkaline phosphatase, X-ray, histopathologic examination and electron microscope were performed.ResultsThe fixation stability of titanium net duck in two groups was good. The bone defect of two groups was repaired. The results of phosphatase, X-ray, histopathologic examination and electron microscope of two groups were not significantly different.ConclusionBionic bone MHA-bBMP is a high bioactivity substitute, and can obtain therapeutic effect equal to iliac autograft when repairing rabbit's femoral shaft defect.
