ObjectivesTo explore the impact of high body mass index (BMI) on irritable bowel syndrome (IBS) in Chinese adolescents.MethodsThe students were randomly selected from middle school and high school. They completed the epidemiological questionnaire of IBS and had their height, body mass measured.ResultsIn total, 1173 students were recruited, including 700 middle school students and 473 high school students. The incidence of overweight/obesity was 30.52%. The incidence of overweight/obesity was not significantly different between boys (28.40%) and girls (32.65%) (P=0.114), and there was not significantly different between students from middle school (30.57%) and high school (30.44%) (P=0.963). Two hundreds and twenty-one students suffered from IBS and the incidence of IBS was 18.84% with no significant gender difference. The incidence of IBS was significantly higher in students from middle school (13.43%) than those from high school (26.85%) (P<0.001). The incidence of IBS was not statistically significant be-tween overweight/obese students (22.07%) and normal weight students (17.42%) (P=0.061). The distribution of IBS subtypes had no statistical significance between overweight/obese and normal weight students (χ2=0.91,P=0.823). ConclusionsOverweight/obesity and IBS were extremely prevalent in Chinese adolescents, but the correlation be-tween them remains to be confirmed.

Background and purpose:Internal mammary sentinel nodes (IMSNs) lymphoscintigraphy could guide in ?-detecting and removing the IMSNs for the purpose of biopsy during the operation,which is helpful to determine the necessity of postoperative radiotherapy. However,IMSNs imaging rate remains low if using axillary lymph nodes (ALNs) lymphoscintigraphy. This study was to investigate the tracer’s properties and try to improve the IMSNs imaging rate through changing the label procedure. Methods:The boiling time of 99mTC-sulphur colloidal particles was shortened from 3~5 minutes to 2 minutes during the label procedure, then the colloidal particles’ diameter, distribution and stability were observed by Transmission Electron Microscope (TEM), then the IMSNs lymphoscintigraphy was performed. Results:This colloidal tracer’s shape and distribution remained stable for 3 hours, and 90% of the particles had a diameter of 10 nm, the particles tended to aggregate afterwards. 4 hours after labeling, the diameter of particles exceeded 100 nm. IMSNs could be clearly imaged if the tracer was freshly used (within 3 hours after labeling). Conclusion:Within 3 hours after the labeling the unfiltered colloidal tracer with modified procedure, the particle could be used and internal mammary lymph nodes could be imaged more clearly.

The serum concentration of vitamin A (VA) and B-carotene were determined in 50 healthy pregnant women in the later trimesters and parturition, their newborns and 20 non-pregnant women. In the meantime the contents of placental tissues were determined too. The results showed; 1. The serum VA content(2.17 umol/L, 62ug/dl)of pregnant women in the later trimesters was higher than that of non-pregnant women (1.37umol/L, 39ug/dl), but it decreased immediately after delivery. 2. There was no significant def-ference of the serum B-carotene concentration between the pregnant women and non-pregnant women. 3. The cord blood VA and B-carotene contents were much lower than those of maternal blood. 4. The contents of B-caro-tene in placentas were 9.6 times as much as VA. 5. The efficiency of transport of B-carotene from maternal blood to placental tissue was higher than that of VA, and lower than that from placenta to cord blood.

Objective To explore the relationship between β2-microglobulin and D-Dimer concentration in the pregnancy-induced hypertension patients with kidney injury.Methods The 120 cases of kidney injury pregnancy-induced hypertension patients were enrolled in our hospital from Nov 2010 to Nov 2015 (served as observation group).The levels of BUN,Scr,UA,β2-microglobulin and D-Dimer were detected.The 100 cases of healthy subjects and 120 cases of normal pregnancy women were taken as controls,respectively.Results Compared with healthy control and normal pregnancy women,the levels of BUN,Scr,UA were increased significantly in the observation group (P<0.05).The results also showed that the expression of NGAL,NLRP3,NADPH oxidase subunits,TGFβ,Smad2,Smad3,β2-microglobulin and D-Dimer were sharply increased as compared with the other two group (P<0.05).Conclusion β2-microglobulin and D-Dimer are significantly related with pregnancy-induced hypertension patients with kidney injury and they would be taken as clinical indicators for the diagnosis of this disease.

[ ABSTRACT] AIM:To investigate the effects of everolimus on the experimental IgA nephropathy in rats and its possible mechanisms .METHODS:The rat model of experimental IgA nephropathy was established .The rats were ran-domly divided into control group , IgA group and everolimus treatment group .After the corresponding treatments were gi-ven, urinary red blood cells , protein and N-acetyl-β-D-glucosaminidase ( NAG) were examined .Immunofluorescence stai-ning was used to analyze the level of IgA precipitation in the renal tissues .Additionally, the protein expression of myeloid differentiation factor 88 (MyD88), TLR4, NF-κB, IL-4 and IL-13 was determined by Western blot.The mRNA levels of IL-4 and IL-13 were detected by qPCR .RESULTS:Everolimus significantly inhibited the increases in the urinary levels of red blood cells, protein and NAG in experimental IgA nephropathy rats .Furthermore, IgA nephropathy-induced increases in the protein expression of MyD88, TLR4, NF-κB, IL-4 and IL-13 were attenuated after everolimus treatment .Similar re-sults were obtained in the mRNA levels of IL-4 and IL-13 by qPCR detection .CONCLUSION: Everolimus improves the impairments of renal function in experimental IgA nephropathy rats as evidenced by decreasing urinary red blood cells , pro-tein and NAG, which may be related to the inhibition of MyD 88, TLR4, NF-κB, IL-4 and IL-13 expression.

The effects of polysaccharidical peptides (PSP) on the functions of tumour infiltrating lymphocytes (TILs) in vitro was explored. The results showed that PSP, at the concentration of 37-1200?g/ml, promoted the proliferation of TILs in dose-related manner. Combination of PSP with interleukin-2 (IL-2) enhanced the cytotoxicity of TILs and reduced the dose of IL-2 used for activating TILs. The results suggested that PSP could augment the proliferation and cytotoxicity of TILs in vitro.
