Chinese Journal of Biochemical Pharmaceutics 2017;37(9):301-303
Objective To study the effect and safety of controlled-release dinoprostone on the induced labor of late pregnancy . Methods 60 cases of late pregnancy puerpera were treated in our hospital from February 2014 to September 2015, and divided into the control group and the experimental group with reference to the stochastic indicator method, 30 cases in each group. The control group were given induced labor by oxytocin, and the experimental group were given induced labor by controlled-release dinoprostone, Changes of Bishop score, effects of promoting cervical mature, induced labor situation, and adverse reaction were compared between two groups. Results After medication, the cervical Bishop score of the group (8.35±0.93) points were significantly higher than (6.64±0.72) of the control group (P<0.05). The total effective rate 96.67%(29/30) of promoting cervical mature in the experimental group was significantly higher than 80.00% (24/30) of the control group (P<0.05). Medicine to clinical time (14.89±1.57)h and total labor time (6.94±1.52) h of the experimental group were significantly better than (21.48±2.35) h and (9.30±1.31) h of the control group (P<0.05). The rate of delivery by vagina of the experimental group 83.33% (25/30) was significantly higher than 60.00% (18/30) of the control group (P<0.05). There was no different on adverse reaction rate between two groups. Conclusion There was good effects of Controlled-release dinoprostone on the induced labor of later pregnancy, with high rate of delivery by vagina and better safety.

Objective To apply fluorescence-activated cell sorting (FACS) and magnetic activated cell sorting (MACS) in sorting natural killer (NK) cells from human peripheral blood. The efficiency of these two methods were compared so that the basic conditions for the further study on the lower proportion of peripheral blood cells could be created. Methods Twenty cases of normal peripheral blood and 3 cases of post-hematopoietic stem cell transplantation (post-HSCT) were collected and NK cell were sorted by FACS and MACS. Results Before sorting the normal peripheral blood, the proportion of the NK cell in the leukocyte was (12.86±3.62) %, the purity of NK cell was up to (96.15±2.03) % and the recovery was (95.08±2.16) %after sorting by FACS, the purity was up to (93.35±3.61) % and the recovery was (94.11±3.01) % by MACS.And before sorting the post-HSCT peripheral blood, the proportion of the NK cell in the leukocyte was (11.01±2.08) %, the purity of NK cell was up to (96.22±2.16) % and the recovery was (95.27±1.18) % after sorting by FACS. The purity was up to (90.98±1.94) % and the recovery was (94.54±3.52) % by MACS. Thereis difference in purity of NK cell (t = 5.925, P <0.05), while no difference in rate of recovery between 2methods (t = 0.789, P >0.05). Conclusion FACS is more efficient, rapidly and easily than MACS in sorting NK cell, especially for post-HSCT cases.

[Summary] Epigenetics defines heritable changes in gene expression that are not coded in the DNA sequence itself.Three systems,including DNA methylation,RNA-associated silencing and histone modification,are used to initiate and sustain epigenetic silencing.Type 2 diabetes mellitus(T2DM) is a polygenic disorder,which is caused by both genetic and environmental factors.However,pathogenesis of T2DM has not been elucidated.Recent studies have indicated that epigenetics may play an important role in the pathogenesis of T2DM,which is involved in the development and differentiation of β cell,secretion of β cell,insulin sensitivity and so on.Researches related to epigenetics may provide a new measure and target to clarify the pathogenesis of T2DM as well as prevent and treat the disease.

Background Recent studies have confirmed that sulforaphane (SFN) can activate multiple pathways,and promote the expression of the antioxidants in cells.Thioredoxin (Trx) plays an important role in maintaining the intracellular redox in the steady state.Objective This study was to investigate the effect and mechanism of SFN on Trx expression in bovine trabecular meshwork cells (BTMCs) cultured in vitro.Methods BTMCs were cultured in vitro and identified by morphological evaluation.The third generation of BTMCs were cultured in the medium with 0,10,20 and 30 μmol/L SFN for 30 minutes.Real-time PCR was applied to measure the expression of Trx mRNA in BTMCs.The BTMCs were randomly divided into normal control group,LY294002 group,U0126 group,SFN group,LY294002 +SFN group and U0126+SFN group.The expressions of Nrf2 protein and Trx protein in each group were measured by Western blot.Results The BTMCs was successfully cultured in vitro.The expressions of Trx mRNA were significantly different among the different concentrationss of SFN treatment (F=88.090,P<0.01).The expressions of Trx protein and Nrf2 protein in the LY294002 +SFN group,U0126 +SFN group and SFN group were significantly higher than those in the normal control group (all at P < 0.01).The expressions of Trx protein and Nrf2 protein in the LY294002+SFN group and U0126+SFN group were significantly higher than those in the SFN group (all at P<0.01).Conelusions SFN can activate Nrf2 by phosphatidylinositol-3-kinase (PI3K)/protein kinase B (Akt) and mitogen-activated protein kinase (MAPK)/extracellular regulated protein kinases 1/2 (ERK1/2) signaling pathways,which can increase the expression level of Trx in BTMCs cultured in vitro.

Effects of acupuncture on spontaneous discharges of nerve cells in ventromedial neucleus of hypothalamus (VNH) and levels of monoamine neurotransmitters in rats of obesity were observed. Results indicated that levels of tyrosine (Tyr) and dopamine f DA) were decreased, and the levels of 5 -hydroxytryptamine (5 - HT) and 5 - hydroxyindole acetic acid (5 - HIAA) increased in VNH; The frequency of spontaneous discharges of nerve cells in VNH lowered significantly in the obesity group as compared with those in the normal group; When acupuncture attained effect of weight reduction, the frequency of spontaneous discharges of nerve cells in the VMH increased obviously; the levels of Tyr, DA, tryptamine , and 5 - HT/5 - HIAA increased, and 5 - HT level decreased in VMH tissue. It is suggested that the benign regulative action of acupuncture on VNH is possibly one of the crucial factors for acupuncture in reducing body weight.
