Objective To obtain the fusion genes of several human orphan G protein coupled receptors (oGPCRs) with Gi1α subtype of G protein and their expression system. Methods The whole open reading frames of GPR45, GPR85, GPR174 and Gilα were cloned by RT-PCR from HepG2 cDNA separately,and the corresponding fusion genes were amplified by overlap extension PCR. Then, the fusion genes-containing pBacmids were successfully constructed with the Bac-to-Bac baculovirus expression system indicated by specific transposition and virus recombination. The insect Sf9 cells were transfected with pBacmid-oGPCRs-Gi1α, and the supernatant containing recombinant virus was harvested. With the supernatant, insect Sf9 cells were infected under an optimized condition (MOI=5, infection time=72 h) and the fusion proteins were prepared and detected by Western blotting.Results The three fusion genes of GPCR45, GPR85 or GPR174 with Gi1α were obtained. The corresponding fusion proteins could be properly prepared in Sf9 cells.Conclusion Human oGPCRs could be fused with Gilα, and the fusion genes could be expressed using the Bac-to-Bac baculovirus expression system in insect Sf9 cells.

The association between thyroglobulin gene polymorphism and autoimmune thyroid disease was investigated.A total of eight case-control studies were included.E33SNP was associated with increased susceptibility of autoimmune thyroid disease in recessive model (OR =1.54,95 % CI 1.21 ~ 1.97,P =0.024),while E12SNP was associated with increased susceptibility of autoimmune thyroid disease in allele model (OR =1.12,95% CI 1.05 ~1.21,P =0.033).Thyroglobulin gene polymorphism seems to be associated with autoimmune thyroid disease.

Objective To study CT-guided localization of additional pulmonary nodules with microcoils prior to video-assisted thoracoscopic surgery (VATS) resection in patients with suspected lung cancer.Methods Eleven patients suspected lung cancer underwent preoperative microcoils localization towards additional small pulmonary nodules.The head of microcoil was pinpointed adjacent to the target nodule while its end tail remained above the visceral pleura.VATS were performed within 24 hours, and comprehensive assessments were conducted according to surgical and pathological outcomes of primary and additional lesions, and suitable surgical processes were followed.Results All 11 localizing pulmonary nodules (4-15 mm in diameter) were successfully removed after VATS, 9 microcoils'' end tails of which were placed above visceral pleural surface.There were no serious complications related with localizing procedure.Other 16 lesions including 11 primary ones were resected.The surgical and pathological outcomes for lung lesions were utterly assessed.Conclusion Microcoil preoperative localization provides helpful orientation for complete resection and assessment of multiple pulmonary lesions in patients with suspected lung cancer.

ObjectiveTo study basic pattern of normal youth in gait analysis.Methods28 healthy young persons as experimental subjects were studied. The gait analysis system based on digital video and digital image processing was employed to obtain kinematic parameters.ResultsThe means and standard deviations of kinematic parameters of normal youth were obtained. The differences of gait patterns between males and females were compared. The correlations between gait parameters and height, weight were analyzed respectively.Conclusions It is recommended that the values of the gait parameters and the trends obtained can be used as a standard gait pattern of normal youth. Statistically significant differences exist between the males and the females for most of the gait parameters. Furthermore, the differences of the values of gait parameters between the males and the females are not led only by the difference of height except very few parameters.

Streptomyces hygroscopicus 17997 produces the antiviral and antitumor ansamycin antibiotic, geldanamycin. Studies on geldanamycin biosynthetic pathway will provide good tools for genetic manipulation of the antibiotic-producing strain to improve the productivity or to facilitate making novel geldanamycin analogs. The structural similarities between geldanamycin and ansamycins such as rifamycin or ansatrienin suggest that both geldanamycin and ansamycins has a closely related pathways of biosynthesis and that biosynthetic system for geldanamycin is similar to the one of type I polyketide synthase (PKS) enzyme system. To explore the possible PKS genes involved in geldanamycin biosynthesis, the degenerate primers were designed according to the conserved sequence of KS-AT region from erythromycin and oleandomycin type I PKS genes. Cosmids containing multiple PKS genes (pCGBK2,4,6,10,11,18) were obtained by hybridization with the PCR products, which were amplified from S. hygroscopisus 17997 genomic DNA. The designed primers above were used for PCR. Development of a Streptomyces temperate phage phiC31-derivative KC515( tsrR) transduction system was carried out for identification of cosmids containing the PKS gene related to biosynthesis of geldanamycin. Several factors, mainly the Ca2+ and Mg + concentrations in different culture media affecting the frequency of gene transfection, were optimized .Transfection efficiency could reach up to 10(3) /microg DNA on YMG medium supplemented with 10mmol/L MgSO4. Reversely, the transfection efficiency decreased when YMG medium was supplemented with 30mmol/L MgSO4. Gene transfection system based on the integration-defective phage KC515 had been established for S. hygroscopicus17997. Recombinant phages (ph111, 258, 287, 116, 105) were constructed by insertion of the homologous to PKS gene fragments into the KC515 phage vector. Gene disruption experiments were performed by transduction of recombinant phages into S. hygroscopicus 17997 genome, and disruption of geldanamycin production was observed as a result of homologous recombination between the cloned insert in recombinant phage and the S. hygroscopicus 17997 genome by integration. Thiostrepton resistant transductants were selected and integration event was analyzed by Southern hybridization. The fermentation broth extracts from five resistant transductants were analyzed by TLC and HPLC. The results showed that only G16 mutant failed to produce geldanamycin. This result showed that the integration of the insert DNA fragment in recombinant phage phl6 into the chromosome of S. hygroscopicus disrupted the expression of the geldanamycin biosynthetic genes. The original cosmid pCGBK10 containing this cloned insert was predicted to encode PKS genes in the geldanamycin biosynthesis. This study laid the foundation for cloning the PKS genes involved in geldanamycin biosynthetic gene cluster from S. hygroscopicus 17997.
