Objective:To analyze the effect of MCT/LCT fat emulsions at different doses on the growth and development of prema-ture and low birth weight infants. Methods: Totally 76 cases of preterm or low birth weight infants were divided into the treatment group (40 cases) and the control group (36 cases), both groups were given MCT/LCT fat emulsions, amino acid and glucose injec-tions in 12-24 h after the birth. The initial dose of MCT/LCT fat emulsions in the treatment group was 2. 0 g·kg-1 ·d-1 and the dose was gradually increased to 3. 0 g·kg-1 ·d-1 with 0. 5 g·kg-1 ·d-1 progressive increase. The initial dose of MCT/LCT fat emulsions in the control group was 0. 5 g·kg-1 ·d-1 , and the dose was increased to 3. 0 g·kg-1 ·d-1 with 0. 5 g·kg-1 ·d-1 progressive in-crease. The treatment course was 7 days. The neonatal weight, serum total bilirubin, direct bilirubin, alanine aminotransferase, total cholesterol, triacylglycerol and blood glucose were monitored in the two groups. Results:The born body mass recovery time of the ob-servation group was (4. 38+0. 93) d, which was significantly shorter than that in the control group [(6. 81+1. 90) d]. After the re-covery, the body weight growth rate of the observation group was (30. 41+1. 81) g·kg-1 ·d-1 , which was significantly higher than that of the control group [(18. 21 +2. 08) g·kg-1 ·d-1, P <0. 05]. After the 7-day treatment, the blood biochemical indices showed no statistically significant difference between the two groups (P>0. 05). Conclusion:Early application of MCT/LCT fat emul-sions at high dose is beneficial to the improvement of nutritional status in premature infants.

To build the Dendrobium nobile -T2DM network, and elucidate the molecular mechanism of D. nobile to type 2 diabetes (T2DM). Collect the chemical composition of D. nobile and the targets on T2DM by retrieving database and documents, build the network of D. nobile to T2DM using the entity grammar systems inference rules. The molecular mechanism of D. nobile to T2DM includes: (1) regulating lipid metabolism by lowering triglyceride; (2) reducing insulin resistance; (3) protecting islet cells; (4) promoting the glucose-dependent insulin tropic peptide (GIP) secretion; (5) inhibiting calcium channel. Under the guidance of network pharmacology, through entity grammar systems inference rules we elucidate the molecular mechanism of D. nobile to T2DM, and provide the basis for the further development of health care products based on D. nobile.

The effects of renal ischemic preconditioning (RIP) on ischemia-reperfused myocardium were examined in the urethane-anesthetized rabbit to determine whether RIP may provide cardioprotection and to observe the role of the renal nerve in such condition. The results obtained are as follows: (1) During 45 min myocardial ischemia and subsequent 180 min reperfusion, blood pressure, heart rate and myocardial oxygen consumption decreased progressively. Epicardial electrographic ST-segment was elevated significantly in the period of ischemia and returned to the baseline gradually in the course of reperfusion. The myocardial infarct size occupied 55.80±1.25% of the area at risk. (2) RIP significantly reduced the myocardial infarct size to 36.51±2.80% (P<0.01), indicating the cardioprotective effect of such an intervention. (3) Renal nerve section (RNS) completely abolished the cardioprotection afforded by RIP, though RNS per se did not affect the myocardial infarct size produced by ischemia-reperfusion. (4) During 10 min renal ischemia, the averaged multi-unit discharge rate of the renal afferent was increased from 0.14±0.08 to 0.65±0.12 imp/s (P<0.01). (5) Pretreatment with an adenosine receptor antagonist 8-phenyltheophylline (10 mg/kg) markedly attenuated the discharge rate of the renal afferent induced by transient renal ischemia, implying that adenosine released in ischemic kidney activated the renal afferent. It is suggested that activation of renal afferents by transient renal ischemia-reperfusion plays an important role in the cardioprotection afforded by RIP.

To explore the influence of glucose level of 75 g oral glucose tolerance test ( OGTT ) druing pregnancy on delivery of large for gestational age infants. This research selected 790 cases of patients diagnosed as gestational diabetes mellitus( GDM) , 478 cases of pregnant women diagnosed as normal glucose tolerance( NGT) from Affiliated Hospital of Jining Medical University in 2014 and followed up until they delivered. Single live births were selected, risk factors which had influence on offsprings, birth weight were analysed. GDM group had significantly higher rate of delivering large for gestational age(LGA)infants than that of NGT group(47. 30% vs 31. 30%, P<0. 05). Adjusting for confounding factors, it suggested that 2 h plasma glucose level of 75 g OGTT was an independent risk factor for the delivery of LGA infants, and 1 mmol/L glucose increment in 75 g OGTT 2 h plasma glucose level, mayincreasetheriskofLGAby29%(OR=1.29,95%CI1.05-1.58,P=0.02). The2hplasmaglucoselevelof75 g OGTT is an independent risk factor for delivery of LGA infants.

Objective To study the influence of progesterone on the cell proliferation of hormone?dependent breast cancer and observe the co?effect of vitamin D and progesterone of different levels on the proliferation of the cell line T?47D in hormone?dependent breast cancer and the interaction be?tween vitamin D and progesterone. Methods The cultured T?47D cells were divided into the high and the low progesterone mono?treated groups to observe the effects of different levels of progesterone on the cell proliferation of hormone?dependent breast cancer cell line(T?47D). The high and the low vitamin D mono?treated groups were set to observe the effects of different levels of vitamin D on the cell proliferation. Groups treated by differ?ent levels of progesterone combined with vitamin D were set to observe the interaction between them. Normal breast cancer cells were set as the con?trol group. The two?factor two?level parallel factorial experiment was conducted to observe the co?effect of different levels of progesterone and vitamin D on the proliferation of T?47D. The growth and apoptosis of cells was observed through detection of absorbance in each group by MTT. Results The cell concentration in high and low progesterone treated groups was increased than that in the control group,and was increased in the low proges?terone treated group compared with the high progesterone treated group(P<0.05). The cell concentration in dual?low level treated group was de?creased than that in the other three groups which were two?factor treated and the control group(P<0.05). Conclusion Progesterone stimulates the cell proliferation of hormone?dependent breast cancer. The concentration?based interaction between vitamin D and progesterone indicates that the bi?directional effect of progesterone on breast cancer cells may be related to the concentration of progesterone and other factors,but the specific interac?tion and the mechanism is unclear.
