Objective:To investigate if injury-related myofibroblast induction could occur in bronchial epithelial cells and the role of TGF-?_1(rhTGF-?_1) in epithelial-myofibroblast transdifferentiation. Methods:Cultured bronchial epithelial cells, 16HBE-14o, were exposed to poly-L-arginine(PLA). Using a immunohistochemical method, ?-smooth muscle actin (?-SMA) expression was detected in those cells after being treated with PLA . Relative activity of chloramphenicol acetyltransferase(CAT) was assessed in 16HBE-14o cells, which were transiently transfected with VSMP8 plasmid containing ?-SMA promoter linked to CAT gene, at different time points after rhTGF-?_1(10 ?g/L) treatment. Results:①?-SMA positive, spindle-shaped cells emerged among the regenerated 16HBE-14o epithelial cells following damage. The number of ?-SMA positive 16HBE-14o cells increased and cell repair was delayed under rhTGF-?_1 stimulation.② CAT activity increased significantly in VSMP8 plasmid transfected 16HBE-14o cells 24 h after TGF-?_1 stimulation.

In the research field of quality control in Chinese medicinal materials, variation in active ingredients of medicinal plant is always the key and hot issues. With the development of high-throughput sequencing technologies and reducing cost, a large numbers of genes from medicinal plant were cloning and provide a solid foundation for further research of gene structure and its biological function, and also provides conditions for explore active ingredient variation and its quality control from the perspective of molecular pharmacognosy. This paper introduces the concept of homologous gene, gene duplication and classification. We prospect the function of duplicated genes in the role of molecular mechanism research about variation in active ingredients, aiming at providing a new way for medicinal materials quality control.

OBJECTIVE:To provide reference for rational use of narcotics drugs in the clinic. METHODS:A total of 5 841 prescriptions of narcotic drugs in our hospital from Jan. 2012 to Dec. 2013 were selected as subjects. The utilization of drugs was an-alyzed statistically using DDDs,DDC and DUI as index. The situation of pharmacists prescriptions dispensing was analyzed with missing rate of unqualified prescriptions as an indicator. RESULTS:7 narcotics drugs DUI≤1.00 in 2012. 9 narcotics drugs DUIs≤1.00 in 2013. The highest missing rate of unqualified prescriptions was 9.33% in the inpatient pharmacy in 2013. The amount and DDDs of Morphine hydrochloride injection,Morphine sulfate sustained-release tablet and Oxycodone sustained-release tablet all in-creased in 2013,compared to in 2012;DUI of all morphine preparation were >1.00. DUI of Codeine phosphate tablet and Bucin-nazine tablet were decreased from 1.64 and 1.11 in 2012 to 1.02 and 0.74 in 2013,tending to be reasonable. The amount and DDDs of Sulfentanyl injection,Remifentanil injection and Fentanyl patch all in 2013,compared to in 2012. CONCLUSIONS:The utilization of narcotics drugs in our hospital basically tend to be rational,but still many deficiencies exist. We should strengthen in-tervention and management on the the utilization of narcotic drugs further.

Objective To investigate the influence of fixation of both lower limbs with negative pressure vacuum cushion and fixation of both ankles with self-made foam mat on setup errors in radiotherapy for rectal cancer.Methods A total of 12 patients with rectal cancer were enrolled in 2014 and randomly divided into group A (using negative pressure vacuum cushion) and group B (using self-made foam mat).An offline registration analysis was performed for the images of 108 times (A,B group of 54 times) of kilovoltage cone-beam CT (CBCT) before and after treatment.Grey scale translation error registration was used,and the results of registration were analyzed.The setup errors in x-axis (left-right direction),y-axis (cranial-caudal direction),and z-axis (anterior-posterior direction) were compared between the two groups.Results There was no significant difference in the absolute setup error in the y-axis between the two groups (2.13±0.64 mm vs.2.61±1.17 mm,P=0.399),while group A showed significantly lower absolute setup errors in the x-axis and z-axis than group B (x-axis:1.51±0.28 mm vs.2.70±1.05 mm,P=0.039;with an error rate of 7.41％ vs.42.59％;z-axis:1.10±0.29 mm vs.2.37±0.71 mm,P=0.002;with an error rate of 1.85％ vs.35.19％).Conclusions In the radiotherapy positioning for rectal cancer,fixation of both lower limbs with negative pressure vacuum cushion effectively avoids the translation and rotation of both lower limbs,reduces absolute setup errors,and has higher accuracy than fixation of both ankles with self-made foam mat.

Objective The mortality rate of the children after surgical repair of congenital heart disease associated with acute renal injure has been reported to be 30％-79％.Peritoneal dialysis is the common treatment method for those patients,but the optimal time to initiate peritoneal dialysis is still controversial.The aim of this study was to investigate the clinic outcome of early peritoneal dialysis to the children following cardiac surgery.Methods We performed a retrospective chart of children following cardiac surgery from January 2008 to December 2009.The total number was 4561,62 of them were performed PD treatment.Data on the PD treatment children were collected from pre-operation to hospital discharge.Early peritoneal dialysis group was defintes as PD initiated at operation room or the interval between the end of operation to starting peritoneal dialysis less than 3hrs.the others were traditional PD group.Results The whole PD treatment rate was 1.36％,15 patients died.The mortality were 10.71％ (3/28) in early PD and 35.29％ (12/34) in conditional PD group respectively (P =0.036).2 patients were met RIFLE(risk,injury,failure,loss,and end-stage renal disease,RIFLE)classification as failure grade in early PD group while 10 patients in traditional PD group (P =0.001).After PD treatment 24hrs,the Vasoactive-Inotrope Scores and serum creatinine values were much lower in the early PD group children than those in the traditional PD group[(19.00 ±2.39) vs(37.00±5.22),P=0.002;(50.51 ±21.84) vs(130.13±76.09),P=0.001)].Conclusion This study shows that early PD can prevent the children after congenital heart surgery to develop AKI,and reduce the severity of the clinic status.Early intervention with PD is associated with low mortality.

50 years).The values of ADC,FA,?_1,?_2 and ?_3 in putamen and globus pallidus were calculated after diffusion tensor scanning,and then analyzed the differences between the two tissues.The differences of ADC,FA,?_1,?_2 and ?_3 values among age groups were analyzed by using analysis of variance(ANOVA),and their relationship with age were accessed by using Pearson correlation.Results Between the correspondent age groups,the ADC value was higher in the putamen[(6.68?0.40)?10~(-4),(6.47?0.36)?10~(-4),(6.44?0.34)?10~(-4)mm~2/s]than that in the golbus pallidus[(6.13?0.50)?10~(-4),(6.05?0.33?10~(-4),(6.05?0.52)?10~(-4)mm~2/s],and the value of FA in the putamen(0.20?0.03,0.23?0.03,0.25?0.03)was lower than that in the globus pallidus(0.35?0.03,0.36?0.03,0.37?0.04).ANOVA analysis of the FA value among age groups revealed there were significant differences in the putamen(F=10.082,P=0.000),and the same analysis of eigenvalue ?_3 in the putamen also showed significant differences(F=5.675,P=0.005).The FA value in the putamen was significantly elevated with aging(r=0.555,P
