The use of optimal regulatory sequences for simultaneous expression of the transgenes might play a significant role in engineering plants with increased disease and insect resistance.The plant expression vector pOMS-GUS,which contained the GUS gene under the control of a chimeric promoter based upon the mannopine synthase(mas)promoter and the octopine synthase(ocs)enhancer,was constructed.Used as control,another vector pMAS-GUS,carried the GUS gene driven by only the mas promoter.The two vectors were introduced into tobacco plants by Agrobacterium-mediated transformation.Fluorometric assays for GUS activity and reverse transcription-polymerase chain reaction(RT-PCR)analysis revealed that GUS gene expressed weakly with untreated transgenic tobacco while the level of GUS activity increased steadily after 1 h subjected to wounding.The expression of the mas and ocs/mas promoters was induced a further 1.8-fold and 5.7-fold,respectively.SA(1 mmol/L)or MJ(250 ?mol/L)treatment also caused a large induction of the ocs/mas chimeric promoter;And the application of SA in combination with MJ(1 mmol/LSA & 250 ?mol/L MJ)produced an additive effect that exceeded the wounding response.The results showed that the ocs/mas chimeric promoter is a strong inducible promoter that can be activated by various stresses.The chimeric promoter should have utility in development of disease and insect resistant transgenic crops.

Clinical data of 2 children with cystic fibrosis (CF) and Pseudomonas aeruginosa infection in the Department of Pediatrics of Sichuan Provincial People′s Hospital from April 2018 to June 2019 were retrospectively analyzed.Patient 1 was an 11-year-old girl with no history of recurrent respiratory infections. Pseudomonas aeruginosa was found in the first sputum culture.A large number of yellow and white secretions were visible under repeated fiberoptic bronchoscopy.Chest CT showed multiple spots and tree-in-bud signs around the bronchi of both lungs. CFTR gene test results revealed 3 heterozygous mutations: c.2909G>A (chr7: 117246728), c.*133T>A (chr7: 117307295) and c. *125delT (chr7: 117307285). The other patient was a 7-year-old boy with a history of recurrent respiratory infections.His parents were close relatives.Multiple cultures of sputum and bronchoalveolar lavage fluid of the boy were Pseudomonas aeruginosa, and chest CT suggested dilation and inflammation in bronchi of both lungs.Gene detection showed that the c. 380T>G homozygous mutation at chromosome chr7-117171059 resulted in an amino acid change p. leu127stop (nonsense mutation). This article suggests that CF should be considered for Pseudomonas aeruginosa infected children having signs of bronchiectasis on chest CT and a large number of secretions under bronchoscopy.Besides, it is necessary for such kind of children to perform genetic testing in time to confirm the diagnosis as soon as possible.

Objective To monitor the change of cardiac function in neonatal sepsis by using the ultrasonic cardiac output monitor(USCOM).Methods Thirty two cases of mild sepsis neonates and nineteen cases of severe sepsis neonates were enrolled and thirty three cases of healthy neonates were enrolled in the control group.The cardiac output indicators of three groups were monitored by USCOM.The differences of cardiac function among 3 groups and the changes of candiac function after treatment in septic neonates were investigated.Results Compared with control group,the heart rate,systemic vascular resistance of mild sepsis neonates group and severe sepsis neonates group were significantly higher,and the cardiac output,systolic volume,cardiac index,aortic peak velocity were significantly lower,the differences were statistically significant(P<0.05).The cardiac index,cardiac output were significactly lower in severe sepsis neonates group than those in mild sepsis neonates group(P<0.05).After improving cardiac function treatment,all cardiac function indexes of sepsis neonates were improved than before treatment,the differences were statistically significant(P<0.05).Conclusion There are significant cardiac function changes in sepsis neonates.The cardiac function and overall circulation state monitoring by USCOM is fast and convenient,and USCOM can provide the basis for treatment and evaluation of the neonatal sepsis.

ObjectiveTo investigate changes of anorectal dysfunction in patients with complete cervical and thoracic spinal cord injury.Methods30 hospitalized cases with complete spinal cord injury and 30 healthy volunteers were performed with anorectal manometry. Changes of manometric characteristics of anorectal and sphincter function were recorded when subjects were resting and bearing down.ResultsDuring defecation, the decreased amplitude of the anal pressure, the pressure gradient between rectal and anal and the index of defecation in patients with complete spinal cord injury were lower than that of in healthy volunteers (P<0.01).Conclusions The anorectal coordination during attempting to defecate and mechanism of initiative defecation were impaired. The mechanism of the reflectivity defecation was the main approach to defecate for patients with complete cervical and thoracic spinal cord injury.

ObjectiveTo evaluate the change of bowel function in patients with spinal cord injury(SCI).Methods70 patients with SCI were reviewed by a face to face interview survey.ResultsThere was highly significant difference between pre and post SCI patients in bowel symptoms, defecation frequency, defecation time, success rate of defecation, toilet dependency and methods of opening bowel.Conclusions There is a high incidence of bowel disorder in patients after SCI. More intensive bowel care programs should be provided for SCI patients.
