Objective To investigate expression of recombinant adenovirus(rAV) vector-mediated report gene in kidney, and to seek for the best passway of rAV vector-mediated gene transfer in vivo.Methods Thirty Sprague-Dawley(SD) rats were divided into 5 groups randomly. rAV-GFP(1013viral particales?L-1) was injected through different ways. 2, 7 and 14 d after injection, GFP expression in left kidney, right kidney, liver and lung was evaluated by fluorescence microscope and computer software. Results GFP gene expressed in kidey and reached peak 7 d after injection expression. Conclusion rAV vector-mediated report gene can be transducted in kidney. The rAV-mediated transgene expression in kidney is a potential strategy in the treatment of renal diseases.

Objective To observe the effects of repetitive transcranial magnetic stimulation (rTMS) on the expression of glial fibrillary acidic protein (GFAP) and OX-42 in hippocampus and dentate gyrus in rats.Methods The rats were treated with 1 Hz, 100 mT TMS 10 min once a day for 14 days, and then the expression of GFAP and OX-42 in hippocampus and dentate gyrus were investigated by ABC technique of immunohistochemistry.Results Compared with the control group, there were no significant difference in the expression of GFAP and OX-42 between the two groups.Conclusion rTMS using our parameters does not cause brain injury in rats.

Objective:To investigate the association between polymorphisms of estrogen receptor ? (ER?) gene (rs3020444) and perimenopausal syndrome (PS) in patients with liver qi stagnation syndrome (LQSS). Metheds:The ER?T/C genotype in 100 patients of PS of LQSS type (PS-LQSS group),86 patients of PS of non-LSDS type (PS-non-LQSS group) and 100 healthy subjects (control) was determined by polymerase chain reaction and restriction fragment length polymorphism (PCR-RFLP) assay. Results:Partitions of ?2 method showed that the higher prevalence of ER?-TT genotypes was noted in PS-LQSS group (?2=8.307,P=0.004),and the higher prevalence of T alleles was noted in PS-LQSS group (?2=7.129,P=0.008). and Multinomial logistic-regression indicated that the odds ratios (OR) of the ER?-TT genotypes vs TC/CC for PS-LQSS was 2.222 (95%CI:1.172-4.744,P=0.015) after adjusting for common miscellaneous factors. Conclusions:It was suggested that ER?-TT genotypes was significantly associated with PS-LQSS,and ESR?-TT may be one of the genes that contribute to PS-LQSS.

Objective To establish a new method for determination of copper, nickel, silver, lead, cadmium and mercury in water with solid phase extraction followed by rapid high performance liquid chromatography. Methods The copper, nickel, silver, lead, cadmium and mercury ions were pre-column derived by tera-(4-dimethylaminophenyl)-porphine (T4-DMAPP). These chelates were enriched by solid phase extraction with C18 cartridge and the 100 times enriched products of were obtained. The chelates were separated on a ZORBAX Stable Bound (4.6 mm?50 mm, 1.8 ?m) by gradient elution with methanol and THF as mobile phase at a flow rate of 2.0 ml/min and detected with photodiode array detector from 350-600 nm. Results The detection limits of nickel, copper, silver, lead, cadmium, and mercury were 3, 2, 4, 3, 1.5 and 3 ng/L respectively, the recovery rates were 92%-104%, relative standard deviations were 2.8%-3.5%. Conclusion This method can be applied to the determination of nickel, copper, silver, lead, cadmium, and mercury in water with good results.

[Objective]To evaluate the methods of operation and clinic effective of thoracolumbar spinal tuberculosis with paraplegia.[Method]Thirty cases of thoracolumbac spinal tuberculosis with paraplegia had been treated with primary anterior debridement,decompression of spinal cord,interbody graft bone,and interbody fixation,anti-tuberculosis drug was taken at 18 monthes ofter the operation.[Result]Thirty cases were followed-up for an overage of 19 months and were healed,in which 2 cases recurrence,29 cases spinal fusion of graft bone,12? of kyphosis correction had been gained,the neuropathic fuction had gained improvement excellently(90%).[Conclusion]It had gained good outcome that operation of the primary anterior debridement decompression of spinal cand interbody graft bone and interbody fixation to treat thoracolumbac spinal tuberculosis with pacaplegia.

Objective To investigate the effects of glucagon-like peptide-1(GLP-1)on the expression of apoptosis-related molecules including programmed cell death 5(PDCD-5)gene in pancreatic ? cells induced by proinflammatory cytokines.Methods Mouse islet ?-cell line NIT-1 was incubated for 24 h with cytokine mixture(Mix)in the absence or presence of GLP-1.The apoptotic cells were assayed by flow cytometry after stained with annexin V-FITC and propidium iodide(PI).The expressions of PDCD5,Fas,and caspase 3 were detected using reverse transcription-polymerase chain reaction(RT-PCR)and Western blot.Results The number of both annexin V single positive cells and annexin V/PI double positive cells significantly increased in the cells treated with 30 U/mL interleukin-1?(IL-1?)+ 100 U/mL interferon-?(IFN-?)+ 100 U/mL tumor necrosis factor-?(TNF-?).The expressions of PDCD5,Fas,and caspase 3 at both mRNA and protein levels were upregulated in the cells exposed to the cytokines.The above-mentioned effects of the cytokines were reversed by 10 nmol/L of GLP-1.Conclusion These data show that the proinflammatory cytokines cause pancreatic ? cell apoptosis via activation of PDCD5 signal pathway and that GLP-1 inhibits the upregulation of PDCD5 expression and the subsequent event of apoptosis induced by the cytokines.

OBJECTIVE:To provide references on how to avoid price war in Chinese drug retailing.METHODS:The status quo of Chinese drug retailing was analyzed,meanwhile the cause and effect of price war were discussed.RESULTS & CONCLUSION:The disadvantages of price war outweigh the advantages,which is sure to be replaced by services-based brand strategy.

Objective To compare the effects of fundus fluorescein angiography (FFA) and indocyanine green angiography (ICGA) on classifications and locations of choroidal neovascularization (CNV) located under subretinal hemorrhage in age-related macular degeneration, and on the area-measuring of subretinal hemorrhage. Methods The medical record of 177 patients with subretinal hemorrhage associated with AMD confirmed by photochrome of ocular fundus, FFA and ICGA examinations were retrospectively reviewed. The locations and classifications of CNV on the images of FFA and ICGA in the 177 patients and the area of subretinal hemorrhage of 30 patients randomly selected from the 177 patients were analyzed and measured. Results On the images of FFA, the locations and classifications of CNV could be defined in 160 patients (90.4%), and CNV was considered eligible for laser therapy in 24 patients (13.6%). On the images of ICGA, the locations and classifications of CNV could be defined in 175 patients (98.9%),and CNV was considered eligible for laser therapy in 51 patients (28.8%). There was no statistical difference of the locations (Z=-0.383,P=0.701) and classifications (?2=2.993,P=0.810) of CNV on the images of FFA and ICGA. The areas of blocked fluorescence measured on the images of FFA (=26.610 mm2 and M= 13.548 mm2) were larger than those of ICGA (=24.714 mm2, M=12.875 mm2) with statistical differences (Z=-3.000,P=0.003) between FFA and ICGA. Conclusions ICGA is beneficial for imaging CNV located under subretinal hemorrhage, and may increase the number of the patients who are considered eligible for laser treatment. The effect of measurement of the area of subretinal hemorrhage in AMD evaluated by FFA is better.
