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.

Objective To assess the relationship between single nucleotide polymorphisms of FcεRIαgene and atopic dermatitis. Methods Genomic DNA samples were extracted from peripheral blood of 97 patients with atopic dermatitis and 283 normal human controls. The polymorphism at the distal promoter region of FcεRIα gene was determined by PCR-ligase detection reaction assay followed by gene sequencing. Results A G/T polymorphism was observed at position rs61828219 in the promoter region of FcεRIα gene, while all the tested individuals were homozygous for T/T at position rs12135235 and A/A at position rs36233780 in the promoter region of FcεRIα gene. The mutation frequency at position rs61828219 was 1.04% and 2.17% in patients with AD and normal human controls, respectively (both P ＞ 0.05). Conclusions In the Chinese Han population, there is a G/T polymorphism at position rs61828219 in FcεRIα gene promoter region, which is unlikely related to the development of AD; however, no polymorphism is detected at position rs12135235 or rs36233780.

Objective To investigate the spatio-temporal expression of P2X3 receptor ( P2X3R) in rats with diabetic mechanical allodynia ( DMA ) .Methods DMA model in rats was induced by intraperitoneal injection of streptozocin ( STZ) .The von Frey filaments were applied to identify the changes of the paw withdrawal threshold ( PWT) in DMA rats.Immunofluorescence was employed to detect the spatio-temporal expression of P2X3R in the spinal dorsal horn (SDH), dorsal root ganglion (DRG) and hind paw skin on different time points after intraperitoneal injection of STZ , respectively.The protein expression of P2X3R in SDH and DRG was further semi-quantitatively analyzed by Western blotting.Results Compared with control group , intraperitoneal injection STZ induced significant mechanical allodynia indicated by the reduced PWT from 7 days, and which reached the peak on 14d and maintained to 28days (P<0.05). The expression of P2X3R in DRG neurons was significantly increased on 14 days and 21 days (P<0.05), while that in SDH and skin was markedly increased on 21 days and 28 days, compared with control group (P<0.05).Conclusion With the progress of DMA, the expression of P2X3R was significantly increased in the SDH, DRG and skin, which was almost parallel with the mechanical allodynia , but the changes in SDH and skin were 1 week later than that in DRG .These results suggest that P2X3R may play a key role in the maintenance of the DMA .

Objective:To explore the relationship between angiotensin converting enzyme (ACE) gene insertion/dele‐tion (I/D) polymorphism and familial essential hypertension (EH) .Methods :Fluorescent in situ hybridization stai‐ning DNA sequencing test was used to detect ACE gene I/D genotype frequency and allele frequency in 46 familial EH patients (familial EH group) ,64 EH patients without family history (non‐familial EH group) and 43 healthy people (healthy control group) .Results:In healthy control group ,non -familial EH group ,familial EH group ACE gene DD genotype frequency was 11.6% ,32.3% and 37.0% ;distribution frequency of D allele was 33.7% , 52.3% and 57.6% respectively .Compared with healthy control group ,there were significant rise in ACE gene DD genotype and D allele frequency in familial EH group and non -familial EH group (P<0.05 or <0.01) ,but there were no significant difference between familial EH group and non‐familial EH group (P>0.05) .Conclusion:ACE gene DD genotype and D allele may be genetic predisposing genes of patients with essential hypertension ,and there is no significant difference in genetic constituent ratio between familial EH patients and non‐familial EH patients .

The article reviewed three aspects of hemiplegic shoulder pain after stroke-introduction, rehabilitation nursing and prospect, in order to provide references for developing effective nursing interventions in the future. We obtained literature from the Cochrane Library, JBI Evidence-based Nursing, PubMed, Wanfang and CNKI Databases between January 2000 and May 2016. According to the principle of three relevant aspects, priority to latest five years and critical appraisal, 39 studies were included. Literature analysis showed that rehabilitation nursing mainly consists of position nursing, supportive devices using, manipulative care and psychological support. Also, it put forward that comprehensive rehabilitation nursing measures have become major means, the combination of Chinese traditional and Western medicine is characteristic therapy in our nation, and nursing practice based on evidence should be set up early to relieve the symptom of hemiplegic shoulder pain and promote quality of life for stroke patients.

Objective To screen the amyloid protein-β(Aβ)degradation-associated genes through peripheral blood monocytes(PBMC)-extracted gene microarray analysis in patients with Alzheimer's disease(AD).Methods PBMC were isolated from blood of elderly AD patients versus age-matched healthy individuals(control).The cDNA(mRNAs)were analyzed using gene microarray.And real-time quantitative polymerase chain reaction detection and enzyme activity analysis were used to verify the primary outcome of gene chip.Results The expression of cathepsin D mRNA in peripheral blood monocytes was 104.70±15.96 in AD patients as compared with the control group 49.86±5.19,and the activity of cathepsin D was (22 620 ± 1 389) RFU in AD versus (32 210 ± 2 284) RFU in control (both P＜0.05).Conclusions The results suggest that the decreased levels of cathepsin D could be the stage markers related to the pathophysiology of AD process.Based on the microarray data,we select cathepsin D genes for further study.
