Objective To describe the depression of premature infants′ mothers and discuss the related influence factors. Methods A total of 86 premature infants′ mothers completed Edinburgh Postnatal Depression Scale at 3-days postpartum in this descriptive study during August 2014 to January 2015 in Obstetrics and Gynecology Hospital of Fudan University. Results The prevalence of postpartum depression in premature infants′ mothers was 25.6% (22/86). Educational levels, family support, character, and number of abortion of mothers, pregnancy complication, gestational age, birth weight, Apgar score, length of hospitalization, and birth with abnormalities of premature infants were found significantly associated with postpartum depression (P<0.05). By Logistic regression, family support (OR=3.253, 95% CI=1.180-8.966) and length of hospitalization (OR=2.905, 95% CI=1.418-5.952) were the risk factors of the postpartum depression at 3-days after delivery. Conclusions Premature infants′mothers at 3-days postpartum presented with obvious postpartum depression. Psychological intervention should be focused on its influence factors.

Two thermotolerant, ethanol-producing yeast cultures: THFY-4 and THFY-16 were isolated from 381 nature samples. THFY-4 can grow on 30% glucose plate at 51 ℃,while THFY-16 can grow on the same medium at 45℃.After preliminary ide ntification, THFY-4 was identified as Kluyveromyces sp. and THFY-16 belon gs to Saccharomyces genus. The ethanol fermentation experiment shows that T HFY-4 can only produce 4.88% (v/v) ethanol from 20% glucose after 60 hours, wh ile THFY-16 can produce 11.44% ethanol under the same condition. When using s accharified Canna edulis Ker wort as fermentation medium, 9.43%(v/v) ethanol we re produced from 16.1% glucose, which is 91.0% of the theoretical yield.

OBJECTIVETo investigate the mechanism that the formulas for activating blood and resolving stasis can regulate hemopoietic stem cell to produce new blood.

METHODRats were established animal model of acute cerebral infarction by referencing Olivette' method. They were randomly divided into model group, the group of the high, middle, low dose of the formulas for activating blood and resolving stasis. Each group and then wasrandomly divided into subgroups by 1, 3, 7, 14, 28 d. Xuesaitong capsule was formulated into 20, 40, 60 g x L(-1) with normal saline. The rats were given gavage drugs once a day until the experient ended, and the model group was administrated by intragastrical perfusion of normal saline. ELISA was used to detect the expression of SCF in peripheral blood and bone marrow among different groups at different time points. Flow cytometry was used to observe the changes of CD117 in blood and bone marrow.

RESULTThe CD117+ HSC and SCF concentration in peripheral blood and bone marrow of model group were increasing during 1-14 d,there was a peak on the 14th day, then the expression was reducing. CD117+ HSC and SCF concentration rising trend in the group of the high, middle dose of the formulas for activating blood and resolving stasis was preceded model group (P < 0.05).

CONCLUSIONActivating blood and resolving stasis can regulate hemopoietic stem cell to produce new blood, and it is through the regulation of CD117+ HSC number to achieve the purpose.

The response of glueagon to the change of glucose and its relation to blood pressure in 71 eidely patients with type 2 diabetes was investigated. The results showed that the postprandial increment of glucagon in the group of patients with postprandial 2h plasma glucose increment<2.5 mmol/L was significantly higher than that in the group with plasma glucose inerement≥ 2.5 mmoi/L (P<0. 05). The postprandial increment of glucagon in patients with normal blood pressure was significantly higher than that in patients with hypertension (P<0.05). The results suggest that the decreased response of glucagon to the change in plasma glucose in elderly patients with type 2 diabetes is related to increased blood glucose and high blood pressure.
