WRKY proteins, a big family of transcription factors, are involved in regulation diverse developmental and physiological processes in plants. Here, a novel WRKY gene, OsWRKY52, was isolated from a rice cDNA library. This gene included an open reading frame of 1 719 bp in length, and the deduced polypeptide contained 572 amino acids,sharing 54% identity with a WRKY1 protein from Avena sativa. Expression of OsWRKY52 gene was induced rapidly by Magnaporthe grisea in the incompatible interaction with rice plant. OsWRKY52 protein, expressed prokaryotically bound specifically to W box cis elements derived from the promoter of a rice PR1a. Transcriptional activation assay was performed by a yeast one- hybrid method. Regions of transactivation were identified to be the N-terminal serine- and threonine-rich islands and the C-terminal acidic domain of OsWRKY52. These results suggest that OsWRKY52, as a transcription activator, may be involved in defense responses against Magnaporthe grisea in rice plants.

Objective To investigate the outcomes of increased gestational diabetes mellitus (GDM) and the influencing factors after the implementation of the new GDM diagnostic criteria.Methods A total of 1 439 GDM women who delivered in the Peking University First Hospital between May 1,2011 and December 31,2012 were studied and divided into two groups.Group Ⅰ included the women who met the new GDM diagnostic criteria (fasting plasma glucose and 1 or 2 h plasma glucose levels for 75-g oral glucose tolerance test performed between 24 and 28 weeks of gestation were no less than 5.1,10.0 and 8.5 mmol/L),but did not meet the National Diabetes Data Group (NDDG) criteria;and Group Ⅱ included the women who met the NDDG criteria only.Women in Group Ⅰ were further divided into two subgroups according to whether attending the one-day GDM outpatient visit.Follow-up rate and detecting rate of abnormal glucose metabolism at 6-12 weeks after delivery were analyzed.Chi-square test,t test and multivariate Logistic analysis were used for statistical analysis.Results There were 849 GDM women in Group Ⅰ (59.0％,849/1 439) and 590 (41.0％,590/1 439) in Group Ⅱ.The follow-up rate in group Ⅰ was lower than in group Ⅱ [25.9％(220/849) vs 32.0％(189/590),x2=6.112,P=0.013].There were five cases of impaired fasting glucose and 34 impaired glucose tolerance in Group Ⅰ;and four cases of impaired fasting glucose,56 impaired glucose tolerance,eight impaired fasting glucose tolerance with impaired glucose tolerance and five diabetes mellitus in Group Ⅱ;there were significant differences [17.7％(39/220) vs 38.6％(73/189),x2=33.810,P=0.000].(2) In Group Ⅰ,the increased glucose level at 2 h in oral glucose tolerance test during pregnancy (OR=1.547,95％CI:1.038-2.306,P=0.032) and family history of diabetes mellitus (OR=1.879,95％CI:1.066-3.313,P=0.020) were risk factors for postpartum abnormal glucose metabolism,while breast-feeding was a protective factor (OR=0.290,95％CI:0.092-0.914,P=0.035).(3) In group Ⅰ,the follow-up rate in those who attended the one-day GDM outpatient visit was higher than those who did not [30.7％(185/603) vs 14.2％(35/246),x2=23.780,P=0.000],but the detecting rate of postpartum abnormal glucose metabolism were similar in women attending the one-day GDM outpatient visit and those not attending [17.8％(33/185) vs 17.1％(6/35),x2=0.020,P=0.887].Conclusions Increased GDM women still have glucose metabolism abnormality after delivery,especially those who have higher glucose level at 2 h after glucose intake in 75 g oral glucose tolerance test during pregnancy and who have a family history of diabetes mellitus.The one day GDM outpatient visit may improve the follow-up rate for these women.

OBJECTIVETo observe the aging law on anti-hypertensive effect of scrapping therapy on primary hypertension so as to provide the reference evidence for the best treatment frequency of scrapping therapy.

METHODSEighty-nine patients of primary hypertension complied with inclusive criteria were treated with scrapping therapy according to syndrome differentiation. The stimulated sites included the courses of the governor vessel and the bladder meridian on the neck and back region, the line from Quchi (LI 11) to Shousanli (LI 10) and that from Zusanli (ST 36) to Fenglong (ST 40). The strong stimulation for reducing attempt was applied to the case of excessi syndrome, determined by subcutaneous capillary rupture and subcutaneous blood stasis. The mild stimulation for reinforcing attempt was applied to the case of deficiency syndrome, determined by subcutaneous capillary hyperemia and skin flush. Each site was scrapped for 10 times, about 5 cm in width, for 15 min. One scrapping treatment was required. The blood pressure was taken as the observation index separately, named 2:00 pm, 2:30 pm, 3:00 pm, 3:30 pm, 4:00 pm, 5:00 pm, 6:00 pm and 8:00 pm one day before scrapping, the time before scrapping in the afternoon on the day of treatment, the moment (2:00 pm), 2:30 pm, 3:00 pm; 3:30 pm, 4:00 pm, 5:00 pm, 6:00 pm and 8:00 pm after scrapping, in 24 h and 48 h after scrapping.

RESULTS(1) After one scrapping, the blood pressure was reduced to be (137. 51±10. 24)/(81. 06±10. 56) mmHg half a hour after scrapping from (149. 00±10. 19)/(85. 30±10. 96) mmHg (1mmHg~0. 133 kPa) before scrapping (P<0. 01). (2) The differences were significant in blood pressure at each time point after scrapping as compared with that before scrapping (all P<0. 01). (3) Through nonlinear regression analysis, the systolic blood pressure after scrapping was increased up to 140 mmHg in 47. 2 h after scrapping.

CONCLUSIONScrapping therapy achieves the apparent immediate anti-hypertensive effect on primary hypertension. It is suitable to apply scrapping treatment once every other day.
