Objective:To investigate esomeprazole combined with early enteral nutrition on the immune function and intestinal flo-ra in the elderly by patients with severe acute pancreatitis. Methods:Totally 78 elderly by patients with severe acute pancreatitis were selected and randomly divided into the observation group (39 cases) and the control group (39 cases). The control group was treated with early enteral nutrition therapy, and the observation group was treated with esomeprazole additionally. The treatment course was 14 days. Results:The total effective rate of the observation group was higher that of the control group (P<0. 05). The abdominal pain relief time, recovery time of bowel sounds, abdominal distension relief time, and the time of serum amylase returning to normal and u-rine amylase returning to normal in the observation group were all better than those in the control group (P<0. 05). The incidence of intestinal flora disorders in the observation group was lower than that in the control group (P<0. 05). After the treatment, CD3+, CD4+ and CD4+/CD8+ increased in both groups (P<0. 05), and those in the observation group were higher than those in the con-trol group (P<0. 05). Serum amylase and urine amylase decreased in both groups after the treatment (P<0. 05), and the decrease in the observation group was more significant than that in the control group (P<0. 05). No serious adverse drug reactions appeared in both groups. Conclusion:Esomeprazole combined with early enteral nutrition in the elderly by patients with severe acute pancreatitis shows significant effect, and the effect may be related with improving the immune function and intestinal flora.

Objective To analyze the CT and MRI performances of chromophobe cell renal carcinoma,to improve the understanding of the disease.Methods The CT and MRI performances of 16 patients with chromophobe cell renal carcinoma confirmed by post-operation pathology were analyzed retrospectively.Results Among 13 cases examined by CT,8 cases had homogeneous lesion including the homogeneous lesions density of 5 cases higher than that of normal renal parenchyma,and the other 5 cases had inhomogeneous density.After enhanced scan,the uneven essence ingredients were markedly enhanced in homogeneous density and inhomogeneous density cases,and the enhancement degree in arterial phase was lower than that of the renal cortex and higher than that of the renal medulla.Among 8 cases checked by MRI,2 cases had signal homogeneity with long T1 weighted imaging and long T2 weighted imaging signal,of which 5 cases appeared high signal in T1 weighted imaging flat lesions.The enhancement mode were similar with CT.In 5 patients examined by CT and MRI at the same time,their density,signal and the pattern strengthening were similar.Conclusions Chromophobe cell renal carcinoma is a rare malignant renal cell carcinoma,and CT and MRI can reflect the composition and hemodynamic changes.When homogeneity and high density or T1WI appeared high signal,disease was large and necrosis was less,and strengthening belt was appeared in lesions,it is value on diagnosis of chromophobe cell renal carcinoma.

METHODSTranswell cubicle was applied to build the co-cultured model in non-contact style. The differences of cell proliferation and the resistance of anti-tumour drug (5-fluoropyrimidinedione, 5-FU and Cisplatin, CDDP) between co-cultured group and single cultured group were evaluated by Cell Counting Kit 8-assay(CCK-8). The invasion ability was detected by Transwell assay. The expressions of stem cell makers, apoptosis-related factors and epithelium-mesenchymal transition (EMT)-related factors were detected by RT-PCR.

RESULTSThe proliferation ability of KATO-III( cells in co-cultured group was significantly stronger than that in single cultured group. The growth rate of KATO-III( cells in co-cultured group was significantly higher than that in single cultured group after treatment of 5-FU and CDDP(P<0.05). The mRNA expression level of Bcl-2 was significantly higher in co-cultured group KATO-III( cells(P<0.05), while the mRNA expression level of Bax was significantly lower in co-cultured group KATO-III( cells(P<0.05) in comparison with those in single cultured group. As compared to KATO-III( cells in single cultured group, the number of infiltrating-membrane cells was significantly higher (37.33±5.22 vs 14.56±2.54, P<0.01) in co-cultured group, and the mRNA expression levels of Snail and N-cadherin were significantly higher in co-cultured group KATO-III( cells (P<0.05), while the mRNA expression level of E-cadherin was significantly lower in co-cultured group KATO-III( cells (P<0.05). The expressions of CD133, Nanog and Sox-2 mRNA in co-cultured group KATO-III( cells were significantly higher than those in single cultured group(P<0.05).

CONCLUSIONSIn co-cultured model sharing non-contact style, BMSC can enhance such properties of KATO-III( gastric cancer cells as the proliferation, the invasion and the chemoresistance. Furthermore, the regulatory mechanisms may be related to the increase of the expressions of some stem cell markers in gastric cancer cells.

Autism spectrum disorder (ASD) is a multifactorial disease, with social difficulties and repetitive behaviors as its core symptoms. With the improvement of diagnostic methods, the detection rate of ASD is increasing year by year.Cognitive flexibility impairment is very obvious in most autistic patients.More and more studies have shown that cognitive flexibility impairment is related to the occurrence and development of core symptoms. However, the mechanism of cognitive flexibility impairment in autism remains unclear. The frontal lobe plays an important role in advanced cognition, and its complete development is related to cognitive function. Recent studies have shown that frontal lobe dysfunction is closely related to cognitive flexibility deficits in autistic patients, and the abnormal changes in the frontal lobe, the associated default mode network dysfunction and frontal striatal circuit defects may be the important mechanisms of cognitive flexibility impairment. Based on the recent clinical and basic studies on cognitive flexibility in autism, this article reviews the mechanisms of frontal lobe and related circuits involved in the impairment of cognitive flexibility in autism.
