The effects of magnolol (Mag) on hyperglycemia and hyperlipemia, hepatic oxidative stress and cytochrome P4502E1 (CYP2E1) activity of diabetic rats induced by high-fat diet (HFD) and streptozotocin (STZ) were studied. After oral administration of Mag (25, 50 and 100 mg x kg(-1) x d(-1)) for continuous 10 weeks, the blood glucose and lipids (TC, TG and LDL-C) levels, as well as the hepatic CYP2E1 activity and MDA content of diabetic rats, decreased significantly (P < 0.05 or P < 0.01), whereas the oral glucose tolerance and hepatic antioxidant enzymatic activities (CAT and GSH-Px) of diabetic rats, increased significantly (P < 0.05 or P < 0.01). The results indicated that Mag was effective against the hepatic oxidative damage, hyperglycemia and hyperlipemia of diabetic rats induced by HFD and STZ, and the inhibition of Mag on hepatic CYP2E1 activity could be an important mechanism of Mag against hepatic insulin resistance and oxidative damage.

This article aimed at exploring the effects and protective mechanism of β-CM7 on renin angiotensin system (RAS) in diabetic rats myocardial tissue. We divided 32 male SD rats into 4 groups: control group, diabetic model control group, insulin (3.7x10(-8) mol/d) treatment group and β-CM7 (7.5x10(-8) mol/d) treatment group. After 30 days, all rats were decapitated and myocardical tissues were collected immediately. After injection, β-CM7 could decrease the content of Ang II, increase the content of Angl-7. And β-CM7 could improve the mRNA of AT1 receptor and Mas receptor. β-CM7 also could improve the mRNA of ACE and ACE2, enhance the activity of ACE and ACE2. These data confirmed tli β-CM7 could activate ACE2-Angl-7-Mas axis, negative passage in RAS, to inhibit the expression ACE mnRiJA and protein in rat myocardium, alleviate the myocardial tissue damage induced by Ang II. The effect of β-CM7 on inhibiting myocardium damage might be related to ACE/ACE2 passageway.

Objective To explore the predictivevalue of Wilms tumor gene 1 (WT1) level on long-term outcome of acute myeloid leukemia(AML).Methods The study in accordance with the inclusion criteria were collected by computer retrieving PubMed,ScienceDirect,EBSCO,Web of Science,CNKI,VIP and Wan Fang database.The retrieval time was from inception to March 2015,the two researchers according to the inclusion and exclusion independently selected studies and extracted the data and assessed the quality,then Revman 5.2 was used for Meta analysis.Results There were 11 relevant published articles were included with 1497 case patients.Meta analysis showed that High expression of WT1 gene was a negative factor for overall survival rate (OS) and disease free survival (DFS) in patients with AML (HR =1.34,95％CI 1.14-1.58,P ＜ 0.01;HR =1.35,95％CI 1.11-1.64,P =0.003).For cytogenetically normal AML patients,the high expression of WT1 gene was still the unfavorable factor of OS (HR =1.41,95％ CI 1.01-1.99,P =0.05).Conclusion WT1 expression level could be an useful prognosis long-term outcome marker for AML patients.

OBJECTIVETo investigate the technique and its effect of combined nasolabial flap and free auricular composite flap for full-thickness nasal alar defect.

METHODSFrom March 2010 to March 2013, 9 patients with full-thickness nasal alar defects were treated with combined nasolabial flaps and free auricular composite flaps. Composite auricular flap was used as inner lining and cartilage framework. The nasolabial flap at the same side was used as outer lining.

RESULTSAll the patients were followed up for 6-18 months (average, 12 months). All the 9 composite auricular flaps survived completely. Epidermal necrosis happened at the distal end of 1 nasolabial flap. Alar rim was almost normal and symmetric nose was achieved in 6 cases. The arc and the thickness of the alar rim was not enough in 3 cases, resulting in asymmetric appearance.

CONCLUSIONSThe survival area of auricular composite flap can be enlarged with nasolabial flap. The auricular helix edge can be reserved to reconstruct nasal alar rim with smooth and natural arc. Large full-thickness nasal alar defedts can be reconstructed with combined nasolabial flaps and free auricular composite flaps.

Objective To evaluate whether estradiol can inhibit and cure the inflammation of experimental preeclampsia in rats. Methods Experimental preeclampsia was induced in 14-day-pregnant rats by infusion of endotoxin (1.0 ?g/kg). Rats with normal pregnancy were infused with sodium chloride solution.A group of preeclampsia rats was injected with 17?-estradiol (17?-E_2, 1 mg?kg -1 ?d -1 ). Blood pressure, albuminuria,inflammation associated adhesion molecule CD_ 49d and tumor necrosis factor-?(TNF-?) were assessed. Results On pregnant day 19, for normal pregnancy group(group C) the blood pressure was (120.4?2.0)mm Hg (1 mm Hg=0.133 kPa),urinary protein (0.47?0.06)mg/24 hours;for experimental preeclampsia group(group A) blood pressure was (134.2?2.4) mm Hg,urinary protein(0.79?0.10)mg/24 hours; for experimental preeclampsia with 17?-E_2 treatment group (group B) blood pressure was(123.3?1.7)mm Hg,urinary protein (0.51?0.08)mg/24 hours. A significant increase of blood pressure and urinary albumin was observed in group A. CD_ 49d expression and TNF-? concentration were also increased. 17?-E_2 reduced the expression of CD_ 49d , concentration of TNF-?,blood pressure and albuminuria of experimental preeclampsia. However, the weight of fetuses in 17?-E_2 treatment group were less than that in other groups. Conclusion 17?-E_2 can improve the symptoms of experimental preeclampsia,but its effects on fetus need to be further studied.

AIM:To investigate the effects of high plasma triglyceride (TG) caused by apolipoprotein C Ⅲ( ApoC Ⅲ) transgene on the occurrence and development of abdominal aortic aneurysm ( AAA) .METHODS:The animal models of hypercholesterolemia and hypercholesterolemia combined with hypertriglyceridemia were established by feeding high-fat diet to LDLR-/-and ApoC Ⅲ+LDLR-/-mice, respectively.AAA was induced in these mice by pancreatic elastase. By evaluating the incidence of AAA, relative maximal abdominal aortic diameter, disruption of the elastic lamellar structure and expression of matrix metalloproteinases ( MMPs) in the aorta walls of the AAA, the occurrence and development of AAA were compared in LDLR-/-and ApoC Ⅲ+LDLR-/-mice fed with either chow diet or high-fat diet.In addition, an in vitro TNF-α-induced aneurysmal microenvironment model on vascular smooth muscle cells ( VSMC) was used to study the impact of triglyceride-rich lipoproteins ( TRLs) from mice with normal or high contents of ApoCⅢon elastin protein expres-sion.RESULTS:Feeding the high-fat diet aggravated the severity of AAA in the LDLR-/-mice.ApoC Ⅲ+LDLR-/-mice fed with high-fat diet had less severe AAA than LDLR-/-mice fed with high-fat diet.TRLs inhibited degradation of VSMC elas-tin protein induced by TNF-α, and in vitro TRLs from the mice with high content of ApoC Ⅲ, compared to those with nor-mal content of ApoC Ⅲ, had better inhibitory effect on the degradation of elastin.CONCLUSION:High plasma TG caused by ApoC Ⅲtransgene alleviates AAA of the LDLR-/-mice induced by elastase and high-fat diet.The effect is probably attrib-uted to the hypertriglyceridemia caused by ApoC Ⅲtransgene.

Objective: To investigate the association between body mass index ( BMI ) and mortality risk among older Chinese based on the China Health and Retirement Longitudinal Study ( CHARLS ). Methods: The demographic features, BMI, prevalence of chronic diseases and mortality among the elderly at ages of 60 years and greater were captured from the CHARLS database from 2011 to 2018. A multivariable Cox proportional hazards regression model was used to examine the association between BMI and the risk of death. Results: Totally 6 023 subjects were enrolled, including 3 006 men ( 50.09% ) and 3 017 women ( 49.91% ), and 68.69% of the participants ( 4 137 subjects ) were at ages of 60 to 69 years. There were 637 subjects ( 10.58% ) with underweight, 1 544 ( 25.63% ) with overweight, and 557 ( 9.25% ) with obesity. During the follow-up period ( 35 091 person-years ), 1 035 subjects died. Multivariable Cox proportional hazards regression analysis revealed an increased risk of mortality among the underweight elderly ( HR=1.496, 95%CI: 1.261-1.775 ) and a reduced risk of mortality among the obese elderly ( HR=0.671, 95%CI: 0.511-0.881 ) relative to the elderly with normal weight, after adjustment for age, gender, smoking, household registration, administration of anti-diabetic drugs, administration of anti-dyslipidemia drugs, and administration of anti-hypertensive drugs. Conclusion It is found that the risk of mortality among the Chinese elderly correlatives with BMI through the analysis of CHARLS data.

Objective To explore the hierarchical chain management model in blood glucose control and its influence factors in patients with diabetes mellitus.Methods Health management database of diabetic patients was established in 2007 and managed by hierarchical chain management.The number of the patients reached to 1010 till 2011.The blood glucose control of diabetic patients was analyzed and its influence factors were analyzed by multivariate unconditional Logistic regression method.Results The concentration of glycosylated hemoglobin( HbA1c ) of 1010 patients with type 2 diabetes was (8.21 ±:2.70)％.Four hundred and eighty-seven cases (48.22％) reached the blood glucose standard,303 cases (30.00％)reached the blood pressure standard,245 cases (24.26％) reached the blood lipids standard,and 76 cases (7.52％) reached all three standards.Multivariate analysis showed that occupation (OR =2.521,95％ CI:1.871 - 3.397),education level (OR =1.890,95％ CI:1.642 - 2.174),disease course (OR =1.035,95％CI:1.016 -1.055),systolic pressure (OR =1.016,95％ CI:1.007 -1.025) and triglyceride (OR =1.204,95％CI:1.063 - 1.365) were the risk factors of blood glucose control (P ＜0.01).Conclusions Hierarchical chain management model is helpful for the blood glucose control in patients with type 2 diabetes.The comprehensive control and treatment of type 2 diabetes should be taken combined with related risk factors,such as blood pressure,blood lipids and diabetes disease course.
