Obesity is a major risk factor for the generation and development of diabetes, atherosclerosis, hyperlipidemia and cancer. Obesity is accompanied with remodeling of adipose tis-sue, such as changed cell component and function, angiogene-sis, extracellular matrix remodeling and infiltration of inflamma-tory cells. It is important for the prevention of obesity to study adipose tissue remodeling. This review summarizes recent ad-vances in adipose tissue remodeling.

AIM:We conducted an evaluation of clinical data with meta analysis to investigate the preventive effect of 5-aminosalicylic acid (5-ASA) on inflammatory bowel disease ( IBD)-associated colorectal cancer ( CRC) or dys-plasia (Dys) (IBD-CRC/Dys).METHODS: The information was retrieved from the main databases such as PubMed, Web of Science, the Cochrane Library, etc.All full-text articles about the prevention of IBD-CRC/Dys by 5-ASA were in-cluded if they conformed to the standards.The odds ratio ( OR) and its 95% confidence interval ( CI) were calculated. According to the types of IBD and the treatment course, the subgroup analysis was conducted, respectively.RESULTS:Fifteen articles were selected, including 5 038 IBD patients.Pooled analysis showed a protective association between 5-ASA and IBD-CRC/Dys (OR=0.53, 95%CI:0.37~0.76).Among them, both ulcerative colitis patients (OR=0.45, 95%CI:0.27~0.77) and Crohn disease patients ( OR=0.39, 95% CI:0.16~0.97) with 5-ASA therapy were less likely to develop CRC/Dys compared with those without 5-ASA treatment.5-ASA treatment for 1~20 years shows a pre-ventive benefit (OR=0.43, 95%CI:0.25~0.74).However, a minimum 5-ASA exposure of 2~6 months did not show a preventive benefit (OR=0.59, 95%CI:0.26~1.34).CONCLUSION:5-ASA protects against CRC/Dys in IBD pa-tients.Additionally, the protective effect is treatment time dependent.Treatment course for 1~20 years shows an evident preventive benefit.

Objective To probe into the epidemic feature, pa tho genic spectrum and main risk factors of diarrhea during the field training in ar my. Methods Detection of morbidity,investigation of risk factor s and detachment of pathogen were performed. Results The diarrh eal incidence rate of army of field training was 4.36%(106/2 433), which was higher than that of hold garrison(0.98%, 2/204). The incidence rate of officers was lower than that of soldiers. Two incidence peaks concerned with the army motion course were foun d. The detection rate of lapactic bacteria from fecal of patients was 63.1%(65/1 03) and most of them were ETEC, followed by the plesiomonas shigelloides.

Objective:To observe the antitumor effect and mechanism of recombinant human endostatin (Endostar) injection in tumor combined with intraperitoneal injection of cisplatin on subcutaneous transplanted Lewis lung cancer in rats.Methods:A total of 30 C57 rats were selected, and the monoplast suspension of Lewis lung cancer was injected into the left axilla to prepare the subcutaneous transplanted tumor models in the axilla of right upper limb. The models were randomly divided into Groups A, B, and C. Medication was conducted when the tumor grew to 400 mm3. Group A was the control group without any interventional treatment. Group B was injected with Endostar 5 mg.kg-1.d for 10 d. Group C was given the injection of Endostar 5 mg.kg-1.d combined with intraperitoneal injection of cisplatin 5 mg.kg-1.d for 10 d. All the rats in three groups were executed the day after the 10-d medication and the tumor was taken off for measurement of volume and mass changes and calculation of antitumor rate, after which the vascular endothelial growth factor (VEGF) concentration in rats’plasma was determined by ELISA. The tumor tissues were cut for the preparation of conventional biopsies. After hematoxylin-eosin staining, the pathologic histology was examined to observe the structures of tumor tissues, VEGF score and microvessel density (MVD) in each group. Results:The volume and mass of tumor in Groups B and C were significantly lower than Group A (P< 0.05) while the tumor volume and mass in Group C were significantly lower than Group B (P < 0.05). The antitumor rate in Group C was significantly higher than Group B (P < 0.05), but the tumor VEGF score, MVD and plasma VEGF level in Group C were significantly lower than Groups A and B (P < 0.05). In Group B, the tumor VEGF score, MVD and plasma VEGF level were significantly lower than Group A (P < 0.05). The microscopic image of Group C showed that its number of active tumor cells and the blood capillary around tumor was significantly smaller than that of Groups A and B, and meanwhile atrophy and liquefactive necrosis were seen in local tumor.Conclusions:Endostar injection combined with intraperitoneal injection of cisplatin is effective in reducing tumor VEGF score and MVD of transplanted tumor tissues in rats with Lewis lung cancer to obstruct the nutrient supply of tumor cells and kill tumor cells, so that the inhibition of tumor cell proliferation and metastasis can be achieved with a remarkable effect.

Objective To investigate serum total IgE levels of healthy population in two hospitals in Yantai and Weihai areas,to investigate the influencing factors of the levels of serum total IgE,which can provide information for the clinical diagnosis of allergic diseases.Methods The total serum IgE level was measured with chemiluminescence method in 1 200 cases of healthy people and 600 cases of smoking group in different age groups.Results The total IgE level of ≤6 years was (28.53±20.71)IU/mL,7-12 years was (29.74±25.94)IU/mL,13-18 years was (32±22.32)IU/mL,19-44 years was (45.2±36.27)IU/mL,45-60 years was (35.47±27.23)IU/mL,>60 years was (31.2±25.03)IU/mL.There was no effect of serum total IgE in different age groups:≤6 years,7-12 years,13-18 years,45-60 years,>60 years(t=0.610,1.508,0.777,0.160,1.518,all P>0.05),19-44 years was significantly different from other age groups(t=0.075,P<0.01).There was no gender difference of serum total IgE in different age groups (P>0.05).The total IgE level of the smoking group:19-44 years was (55.22±39.16)IU/mL,45-60 years was (42.63±28.46)IU/mL,>60 years was (39.32±26.73)IU/mL.The level of serum IgE in the smoking group was significantly higher than that in the same age group (t=0.142,0.174,0.235,all P<0.05).Conclusion No significant difference existed in healthy people of serum total IgE levels from birth to adulthood.However,the total IgE level rose when reached to 19-44 years,which then slightly declined as the growth of the age.There was no significant difference between male and female of the IgE levels in different age groups.But after the age of 19,smoking can lead to the increase of the total IgE level.

In order to explore a potential indicator of predicting the occurrence and development of gestational trophoblastic tumor, the expression of c-erbB2 oncogene in human normal placenta, hydatidiform mole and choriocarcinoma was investigated. The expression of c-erbB2 was detected immunohistochemically by monoclonal antibody against the gene on the formalin-fixed paraffin sections of 21 hydatidiform moles, 21 invasive moles, 20 choriocarcinomas and 30 normal placentas. Results showed that the expression level of c-erbB2 was significantly higher in gestational trophoblastic tumor than in hydatidiform mole and normal placenta of midterm and term pregnancy (P < 0.05), while there was no significant difference between patients with gestational trophoblastic tumor of stage III, IV and those of stage I, II. It was demonstrated that overexpression of c-erbB2 may closely associated with malignant transformation of hydatidiform mole, not only providing important insight into pathogenesis of gestational trophoblastic tumor, but also having an important significance for the early diagnosis and early treatment of gestational trophoblastic tumor.

To investigate the expression and implication of survivin protein and mRNA in decidua and villus and the effects of mifepristone on its expression, survivin levels in decidua and villus collected from 15 normal early pregnant women and 15 early pregnant women pretreated with 150 mg mifepristone and 400 micrograms misoprostol were assessed by immuno-histochemical techniques and reverse transcriptional-polymerase chain reaction (RT-PCR). Our results showed that survivin proteins were stained in the cytoplasm of trophoblasts and decidual cells and in the nuclei of some of the decidual glandular epithelial cells. The expression was strongest in the trophoblasts and decidual glandular epithelial cells. The expression values in the villus and decidua were (14.56 +/- 2.44) and (10.46 +/- 2.81) respectively for normal pregnant and (8.45 +/- 2.08), (7.33 +/- 1.91) for those pretreated with mifepristone respectively (P < 0.05). The transcription of survivin mRNA in villus and decidua of those pretreated with mifepristone decreased significantly compared with those in the normal pregnant women (P < 0.05). It is concluded that survivin can be expressed in the decidua and villus and mifepristone inhibits its mRNA transcription and protein expression, which could possibly be one of the factors inducing decidual and villous apoptosis.
