Cancer cells display a decreased mitochondrial respiration along with an abnormal activation of glycolysis to satisfy the demand of the malignant growth even in the presence of oxygen.This phenomenon may be caused by mitochondrial dysfunction,hypoxia of microenvironment and the abnormal activation of upstream regulators of glycolysis pathway.Treatment targeted at the glycolysis pathway and its upstream regulators may provide a new therapeutic strategy of cancer.

Objective To investigate the relationship between the intercellular adhesion molecule-1(ICAM-1) and lymphocyte function associated with antigen-1( LFA-1) and acute rejection of liver transplantation in rats. Methods SD rats and Wistar rats were randomly divided into normal control group, isograft group, and allograft group. Liver biopsies from the recipients were obtained on the day 2,4, and 7 postoperatively to examine the expression level of ICAM-1 and LFA-1 in liver grafts. Samples were firstly stained with specific monoclonal antibodies using immunohistochemistry stain and then applied to image semiquantitive analysis. Results The expression levels of ICAM-1 and LFA-1 in allograft group were obviously higher than those in both isograft group and normal group. Moreover, the expression levels of ICAM-1 and LFA-1 were correlated positively with the degree of acute liver rejection. Conclusions Detecting the expressions of ICAM-1 and LFA-1 in liver graft tissue may be helpful to the diagnosis of acute rejection after liver transplantation.

【Objective】To investigate the relationship between the expression of lymphocyte function-associated antigen-1 (LFA-1) on peripheral lymphocytes and acute rejection after orthotopic liver transplantation (OLTx) in rat.【Methods】Adult male rats were divided into 2 groups.In the non-rejection group,40 SD rats were used as both donors and recipients.In the rejection group,20 Wistar rats were used as donors and 20 SD rats as recipients.Blood samples were collected through the tail vein 1 day before transplantation and on days 1、3、5、7 after OLTx.The expression of LFA-1 (CD11a) on peripheral lymphocytes was analyzed by using indirect immunofluorescent marker-flow cytometry.【Results】The expression level of LFA-1 on peripheral lymphocytes in recipient rats after orthotopic liver transplantation was markedly lower than that before operation (P<0.01);The expression level of LFA-1 on peripheral lymphocytes in rats with acute liver rejection was significantly higher than that in the non-rejection group (P<0.01).【Conclusion】Monitoring the expression level of LFA-1 on peripheral lymphocytes may be helpful to the diagnosis of acute graft rejection.

Objective:To investigate the effects of Nano-chitosan rhBMP-2 Gel(NCS/BMP-2 Gel)on the repair of mandibular de-fect.Methods:NCS/BMP-2 Gel and NCS Gel were prepared and respectively injected into the subcutaneous space on both sides of dorsum of 9 rats.3 rats were respectively sacrificed 10,20 and 30 d after injection.The subcutaneous nodules were histologicaly ex-amined.Mandibular defect was made in 54 SD rats and the rats were divided randomly and into 3 groups(n=18):NCS/BMP-2 Gel was implanted into the defects in group 1,NCS Gel in group 2,no injection in group 3.Animals were sacrificed 3,6 and 9 weeks after transplantation.X-ray examination,pathologic observation were conducted.Results:Subcutaneous nodules were found in both sides of the rat dorsum.The residual mandibular defect area in study group 1 was apparently smaller than that in group 2 and 3(P<0.05). More new bone formation was observed in the gel injected area in group 1 than in group 2 and 3.Conclusion:Nano-CS/BMP-2 Gel is biocompatible and can accelerate the healing of mandibular defect.

AIM:To study the protective effect and mechanism of Gujingdan(Radix Astragali,Fructus Alpiniae oxyphyllae,Radix et Rhizoma Salviae miltiorrhizae,Herba Epimedii,Semen Euryales,etc.) on the acute renal injury caused by Gentamicin in rats.METHODS:90 rats were randomly divided into normal control group,pathologic model group,preventive group which included high,middle and low dosages of Gujingdan(4 g/kg,2 g/kg,1 g/kg) and positive control group which was treated with Shenkangning(2 g/kg) and treated group which included the same groups as the preventive group.The preventive groups were respectively given Gujingdan and Shenkangning for two weeks and ahead one week.On the seventh day,except the normal group the others were continuously injected gentamicin by abdominal cavity(100 mg/kg/day) seven days.At the same time,the treated group were given Gujingdan and Shenkangning by ig for seven days.When the experiment was over,the content of ?-N-acetyglocosamidase(NAG),serum creatinine(SCR) and blood urea nitrogen(BUN) were examined,and the renal histological changes were observed.RESULTS:NAG,BUN,SCR of the groups which were treated with Gujingdan were remarkly lower than that of the pathologic model group;SOD、ATP were higher and MDA was lower than that of the model group.Histological changes showed that renal tubular epithelial cells of the groups treated with Gujingdan were similar to the changes of normal group and much better than that of positive group and pathologic model group.CONCLUSION:Gujingdan has the protective effect on acute renal injury caused by Gentamicin.The mechanism may be that Gujingdan has the function of inhibiting oxidation,protecting and stabilizing cell membrane.

Objective · To compare the prevalence of tobacco advertisement before and after implementation of the new edition of Advertising Law of the People's Republic of China and evaluate the effects of implementation of the new Advertising Law. Methods · Tobacco sales places, public places, and streets in Shanghai were randomly selected to observe tobacco advertisement and complete the survey. The survey was carried out in 10 districts of Shanghai in June 2015 with 10 tobacco sales places selected in each district, and in 4 districts of Shanghai in June 2016 with 25 tobacco sales places selected in each district. Sales places included convenient stores, tobacco stores, supermarkets, and kiosks. In addition, public transport waiting points, public transport vehicles, hospitals, shopping centers, restaurants, bars, and Internet cafes were selected into survey in 2016. Results · In 2016, the proportion of tobacco sales places having tobacco advertisement was lower than that in 2015, but the proportion of tobacco promotion behaviors was higher. In 2016, 128 public places and streets were investigated and only 1 had outdoor tobacco advertisement. Conclusion · The new edition of Advertising Law has significant effect on controlling tobacco advertisement, but tobacco sales places still have tobacco advertisement with various disguised promotion forms. Tobacco sales places have diversified business styles and minors often enter these places. It is recommended that a clear definition of disguised forms of tobacco advertisement should be made, tobacco advertisement at tobacco sales places needs to be supervised, the release of tobacco advertisement should be strictly reviewed, and existing tobacco advertisement should be severely punished, so as to prevent minors from exposing to tobacco advertisement and information luring smoking.

BACKGROUND:Absorption and atrophy of the alveolar ridge always happen after tooth extraction. There are stil a lot of difficulties to be worked out to prevent the atrophy of the alveolar ridge. OBJECTIVE:To investigate the effect of the nano-chitosan/bone morphogenetic protein hydrogel on preventing absorption of the residual alveolar ridge of the rats. METHODS:Total y 54 Sprague-Dawley rats were divided randomly and equal y into three groups. A model of residual alveolar ridge was made by extraction of the left central incisor. Nano-chitosan bone morphogenetic protein hydrogel was implanted into the rat’s alveolar fossa of the experimental group;the alveolar fossa of the control group was implanted with nano-chitosan hydrogel;the alveolar fossa of the blank group was implanted with nothing. Rat’s mandible was ful y dissected after 3, 6, 9 weeks, respectively. Molybdenum target X-ray examination and pathological observation were evaluated. RESULTS AND CONCLUSION:At weeks 3, 6, 9 postoperation, the residual alveolar ridge was absorbed to different degrees, which was milder in the experimental group than the cotrol group and blank group (P<0.05). After 3 weeks, in the blank group, less new bone formed, but bleeding and a large amount of inflammatory cells were visible; in the control group, a few of osteoid tissues and lymphocytes were found; in the experimental group,new bone formed and a small amount of inflammatory cells were observed. After 6 weeks, new bone formed obviously in the experimental group, a little new bone formed in the control group, but less new bone formed in the blank group. After 9 weeks, a large amount of new bone formed in the experimental group with good osteogenic ability; only a few of new bone formed in the control and blank groups. Nano-chitosan/bone morphogenetic protein hydrogel can be used to prevent the absorption of the residual alveolar ridge after tooth extraction.
