This study examined the construction of eukaryotic expression plasmid of human transforming growth factor-β3 (hTGF-β3) and its inducing effect on the differentiation of precartilaginous stem cells (PSCs) into chondroblasts. hTGF-β3 gene was amplified by using polymerase chain reaction (PCR) and then inserted into the eukaryotic expression plasmid pcDNA3.1 to construct the eukaryotic expression plasmid pcDNA3.1(+)-hTGF-β3. Rat PSCs were isolated and purified by employing an immunomagnetic cell sorting system. pcDNA3.1(+)-hTGF-β3 was transfected into purified PSCs with the use of linear polyamines. The expression of TGF-β3 and cartilage-specific extracellular matrix (ECM) components was detected after transfection by real-time quantitative PCR, ELISA, immunochemistry and Western blotting, respectively. The results showed that the eukaryotic expression plasmid pcDNA3.1(+)-hTGF-β3 was successfully established as identified by enzyme digestion and DNA sequencing. Real-time quantitative PCR and ELISA revealed that hTGF-β3 was strongly expressed in pcDNA3.1(+)-hTGF-β3-transfected PSCs. Real-time quantitative PCR, immunochemistry and Western blotting showed that the cartilage-specific ECM markers, i.e., cartilage oligomeric matrix protein (COMP), Aggrecan, collagen type X and II were intensely expressed in the pcDNA3.1(+)-hTGF-β3-transfected cells. It was concluded that hTGF-β3 could be stably expressed in pcDNA3.1(+)-hTGF-β3-transfected PSCs and induce the differentiation of PSCs into chondroblasts.

Objective To explore the health-relate quality of life(QOL) status of adult persistent allergic rhinitis (PAR);the change of QOL of pro-post specific immunotherapy (SIT) and pharmacotherapy .Methods Skin prick tests(SPT) were performed on PAR patients .According to the results ,80 adult cases that were allergic to dermatophagoides were enrolled in ENT outpatient clinic of affiliated hospital of Nantong University from April to August 2011 .The patients were randomly allocated to receive either specific immunotherapy(n=40) or pharmacotherapy (n=40) ,all of them were given RQLQ before and after half-year treatment ;40 cases without any allergic diseases were chosen from ENT in-patient department ,and were given RQLQ .The scores of previous treatment of the PAR group were compared with health control group ,then compared with the scores of post-treatment ,and also compared the scores of post-treatment between the immunotherapy group and pharmacotherapy group .Results The scores of the PAR patients were higher than that of health control patients in all dimensions of RQLQ (P< 0 .05) ,and the most troublesome problems were nasal symptoms .The scores of the patients who received SIT were evidently lower than that of pro-treatment in all dimensions of RQLQ(P<0 .05) ,the scores of the patients who received medical treatment were also lower than before (P<0 .05) , and the scores of the SIT group were lower than the pharmacotherapy group (P<0 .05) .Conclusion The QOL of adult patients with PAR was improved after SIT or drug treatment ,and QOL improvement is more obvious treat by SIT .

OBJECTIVE:To provide reference for rational use of antibacterial drugs in the clinic. METHODS:In retrospective study,outpatient and emergency antibacterial drugs prescriptions were randomly selected from a hospital during 2013-2014,and then analyzed statistically. DDDs of antibacterial drugs were analyzed by using DDD method. RESULTS:From 2013-2014,the ap-plication rate of antibacterial drugs in the hospital declined substantially from 13.8% to 11.9%,and the rate of irrational use dropped from 2.7% to 1.2%. The application rate of antibacterial drugs was higher in pediatric department,emergency department and urology department;drug cost per capita was higher in infectious department,nephrology department and emergency depart-ment. The application rate of antibacterial drugs in pediatric department decreased greatly in 2014,compared with 2013,maintain-ing about 40%. The application rate of antibacterial drugs in emergency department during Jan.-Sept. in 2014 was lower than corre-sponding period in 2013,and that of the hospital during Jan.-Sept. in 2014 was lower than corresponding period in 2013,but dur-ing Oct.-Dec. in 2014 was slightly higher than corresponding period in 2013. Single type of antibacterial drugs were mainly used in outpatient department,accounting for 91.50% and 90.77% of antibacterial drug prescriptions in 2013 and 2014;two-drug account-ed for 8.44% and 9.11%. The top 3 antibacterial drugs in the list of DDDs during 2013-2014 were roxithromycin,cefuroxime and cefminox. CONCLUSIONS:The use of antibacterial drugs is up to the requirements of Nation Special Rectification Actirity for Clin-ical Application of Antibacterial Drugs in 2013. The prescription comment improve the quality of antibacterial drug prescriptions and rational use index greatly in outpatient department,but the application rate of antibacterial drugs is too high in some depart-ment. There still is irrational use of antibacterial drugs.
