Objective To explore the possibility of heterodimerization between orexin type 2α receptor (OX2αR) and orexin type 2β receptor (OX2βR).Methods Using confocal laser scanning microscope,enzyme linked immunosorbent assay (ELISA),fluorescence resonance energy transfer (FRET) and Bioluminescence resonance energy transfer (BRET) to study the interaction between OX2αR and OX2βR.Result Confocal laser scanning microscope and ELISA showed that OX2αR and OX2βR were both expressed in the cytoplasm.The FRET demonstrated that the signal of the experimental group (OX2αR-YFP+ OX2βR-CFP) was significantly stronger than that of control group (YFP+OX2βR-CFP).The BRET value of the experimental group (OX2αR-YFP+OX2βR-Rluc,mBRET ratio was 65± 15) was higher than that of control group (YFP+ OX2βR-Rluc/OX2αR-YFP+Rluc,mBRET ratio was 10±5) (P＜0.05).Conclusion There are heterodimerization between mOX2αR and mOX2βR.

Objective To evaluate the efficacy of DSA-guided percutaneous transhepatic gallbladder catheter drainage (PTGCD) in treating aged patients with acute cholecystitis complicated by severe diseases. Methods The clinical data of 15 aged patients with acute cholecystitis or complicated by severe diseases, who were encountered at authors’ hospital in the past three years and were treated with PTGCD, were retrospectively analyzed. The clinical results were discussed. Results PTGCD was successfully accomplished with single procedure in all 15 patients. Abdominal pain was relieved within one to three days, and the abdominal symptoms and signs subsided or disappeared. Reexamination of routine blood test showed that the white blood cell count decreased to normal range in 1 - 2 weeks, and complete cure was achieved in some patients. Secondary surgery was carried out in some patients after the clinical condition was improved. During the follow-up period no complications occurred in all patients except one who developed biliary leakage after the catheter was retrieved two weeks after the treatment. Conclusion For the treatment of complicated acute cholecystitis in aged patients who are not suitable to receive surgery, DSA-guided percutaneous transhepatic gallbladder catheter drainage is an ideal therapeutic means as it can significantly relieve clinical symptoms.

2', 3', 5'-Tri-O-acetyl-N6-(3-hydroxylaniline)adenosine (WS070117) is a derivative compound of natural product cordycepin. It has significant lipids regulating activity and low toxicity which has been proved by in vitro and in vivo experiments. In this study, 1H NMR-based metabolomics was used to investigate the dose-related effects of WS070117 on hyperlipidemia of high-fat-fed hamsters. The hyperlipidemic hamsters were administrated with six different doses of WS070117, including 3, 12, 50, 100, 200 and 400 mg x kg(-1) x d(-1). 1H NMR spectra of hamster serum were visually and statistically analyzed using two multivariate analyses: principal component analysis (PCA) and orthogonal partial least squares-discriminant analysis (OPLS-DA). As a result, WS070117-treated groups showed dose-related regulation of metabolites associated with lipid metabolism, choline metabolism and glucose metabolism. The dose of 3 mg x kg(-1) x d(-1) of WS070117 only exhibited a little lipids regulating activity. However, the doses of 12 and 50 mg x kg(-1) x d(-1) of WS070117 both regulated the contents of metabolites to reverse significantly toward normal levels. When the dose of WS070117 reached 100 mg x kg(-1) x d(-1), it was more effective than positive control drugs. The work suggested that NMR-based metabolomics might be a valuable approach to evaluate dose-related effects of lipids regulating compounds.

BackgroundWhether the peeling of the inner limiting membrane (ILMP) increase the closure rate of idiopathic macular hole is still in controversy.Some ophthalmologist recommend vitrectomy combined with inner limiting membrane peeling for the treatment of idiopathic macular hole.However,the removal of ILMP is difficult because of its similar appearance to adjacent tissues.Objective This study was to investigate the efficacy of triamcinolone acetonide(TA) and indocyanine green(ICG) double staining-assisted vitrectomy combined with ILM peeling during the surgery.Methods A consecutive case- observational study was designed.The standardized vitrectomy was performed in 25 eye of 23 cases with IMH.During the vitrectomy,TA and ICG were injected into posterior pole vitreous to visualize and assist the ILM peeling.The dying effectiveness was observed,and the closure rate of macular hole,visual acuity,intraocular pressure and complications were evaluated after surgery.Written informed consent was obtained from each patient prior to operation.Results Posterior vitreous cortex and ILM were visible and the residual vitreous and cortex were removed clearly after dying of TA and ICG in all the 25 eyes.During the following-up duration of 3-8 months,the completely anatomical reattachment of the macular area was in 22 eyes ( 88.0％ ) and partially reattachment in 3 eyes( 12.0％ ).The best corrected vision was 0.07-0.60 in all of the operated eyes 2 months after surgery.Conclusions TA and ICG- assisted vitrectomy combined with ILM peeling appears to be a safe and effective method for IMH repair.

The Her-2 proto-oncogene encodes a 185kDa transmenbrane glycoprotein p185 which has intrinsic tyrosine kinase activity. It is overexpressed in several malignant human tumors like breast cancer. A chimeric antibody by assembling a single-chain Fv antibody and a human IgG1 Fc fragment was constructed. This chimeric antibody reacts with tumor surface antigen p185c-erbB-2 specifically. In order to put the antibody into clinical application, two steps purification method was used to attain the antibody’s purity more than 95%. Both the lyophilized pharmaceutical formulations of the antibody were found. The formulations can keep the stability and activity of the antibody for at least one year. These results were the foundation of the chimeric antibody for cancer therapy.

Objective To establish and evaluate a gene microarray for determination katG mutations of Mycobacterium tuberculosis isolates associated with resistance to isoniazid(INH).Methods A panel of probes were designed and gene chips were prepared by dotting.Mycobacterium tuberculosis isolates resistance to 5 drugs was determined by proportional dilution methods.Amplicons of Mycobacterium tuberculosis isolates were detected by our chip and sequenced.Results The drug resistance rate of the isolates to at least one of the anti-tuberculosis drugs was 70.8%(97/137).45 strains out 137 Mycobacterium tuberculosis isolates was resistant to INH(32.8%).katG was successfully amplified from 100% of the susceptible strains and 88.9%(40/45)resistant strains.4 of 45 INH resistant isolates' katG were deleted.27 of 40(67.5%) katG has been detected to have katG 315 codon mutations.The mutations were 315 AAC(Asn,13/40), ACC(Thr,6/40),ACA(Thr,4/40),ATC(Ile,2/40),AGC(Arg,2/40).The mutation rate of katG analyzed by gene chips we prepared were identical to katG sequencing.Conclusion The gene microarray techniques we developed for determination of Mycobacterium tuberculosis resistance to INH are specific, sensitive and may be used as an alternative in clinical laboratory.
