Insulinoma (islet β-cell tumor) is one of the most common pancreatic endocrine tumors. It has a typical clinical manifestation called Whipple's triad. And so far, surgical treatment is the only curative method. But the localization diagnosis of insulinoma is difficult. Recently, with advances in diagnostic tech-niques, the localization diagnosis of insulinoma accuracy has markedly improved. This paper makes a brief overview of the progress in diagnosis and treatment of insulinoma.

Objective To investigate the effect of solute cartier organic anion transporter family, member 1B1 (SLCOIBI) gene variants on the response to therapy with repaglinide in type 2 diabetes. Methods 100 newly-diagnosed type 2 diabetic patients were treated with repaglinide during a course of 48 weeks. Anthropometrie parameters and indices related to glucose metabolism were measured periodically. Genotypes of SLCO1B1 D130N and V174A were detected by PCR-restriction fragment length polymorphism (RFLP) and sequencing respectively. Results Eighty-nine patients accomplished the 48-week follow-up visits. D130N variant in SLCO1B1 gene was associated with repaglinide treatment, DD genotype had better HbA1C lowering effect than N allele carrier [△HbA1C: (-2.29±0.23) % vs (-1.49±0.21)%, P<0.05]. No association was detected between D130N and the other effects of repaglinide on glucose metabolism related phenotypes. Conclusion D130N variant in SLCO1B1 gene is associated with the response to repaglinide treatment in patients with type 2 diabetes. DD homozygotes had a better effect than N allele carriers.

Objective To explore the effects and mechanisms of hepatitis B virus-X protein (HBx) on invasion and migration of hepatocellular carcinoma (HCC) cells.Methods The retrospective cohort study was conducted.The clinicopathological data of 30 patients with liver tumor (20 with HCC and 10 with benign tumor of liver) who were admitted to the Affiliated Hospital of Xuzhou Medical College between July 2014 and July 2015 were collected.HCC tissues of 20 patients with HCC (with history of HBV infection) were collected by surgical resection and peritumoral normal tissues (outside of tumor capsule) of 10 patients with benign tumor of liver (without history of HBV infection) were collected.The expressions of epidermal growth factor receptor 3 (ErbB3)in HCC tissues and peritumoral normal tissues were detected by immunohistochemistry (IHC).The relative expressions of ErbB3 and HBx in HCC tissues and peritumoral normal tissues were detected by Western blot,and relative expressions of ErbB3 in HepG2 of which green fluorescent protein (GFP) and GFP-HBx were respectively transfected were detected.The relative expressions of ErbB3 mRNA in HepG2 transfected by GFP and GFP-HBx were detected by real-time polymerase chain reaction (RT-PCR).The migration and invasion of HepG2 were respectively detected by Transwell assay with and without matrix.The measurement data with normal distribution were represented as $± s.The comparisons between groups were evaluated with the independent-sample t test.Correlation analysis was done by the Pearson test.Results (1) The expressions of ErbB3 were detected by IHC:relative value of mean optical density (MOD) of ErbB3 in HCC tissues of 20 patients with HCC and peritumoral normal tissues of 10 patients with benign tumor of liver were 2.54± 1.33 and O.99±0.29,respectively,with a statistically significant difference (t =6.542,P ＜ 0.05).(2) The relative expressions of ErbB3 and HBx were detected by Western blot:relative expressions of ErbB3 and HBx were respectively 0.79±0.13,1.10±0.28 in HCC tissues of 10 patients with HCC and 1.07±0.17,0 in peritumoral normal tissues of 10 patients with benign tumor of liver,with statistically significant differences (t =3.229,19.486,P＜0.05).The results of Pearson test showed that there was a positive correlation of expression between ErbB3 and HBx in HCC tissues (r=O.637,P＜ 0.05).(3) The relative expressions and transcriptional levels of ErbB3 were detected by Western blot and RT-PCR:relative expressions of ErbB3 in HepG2 of which GFP and GFP-HBx were respectively transfected were O.75±0.11 and 1.10±0.10,respectively,with a statistically significant difference (t=4.291,P＜0.05).The relative expressions of ErbB3 mRNA in HepG2 of which GFP and GFP-HBx were respectively transfected were O.38±0.03 and O.94±0.07,respectively,with a statistically significant difference (t=11.703,P＜O.05).(4) The effects of ErbB3 on migration and invasion of HepG2:numbers of transmenbrane cell in HepG2 of which His and His-ErbB3 were respectively transfected by Transwell assay with matrix were respectively 271± 18 and 463± 31,respectively,with a statistically significant difference (t =8.202,P＜0.05).Numbers of transmenbrane cell in HepG2 of which His and His-ErbB3 were respectively transfected by Transwell assay without matrix were respectively 315±38 and 549±34,respectively,with a statistically significant difference (t =8.310,P＜0.05).Conclusion HBx protein can promote the invasion and migration of hepatocellular carcinoma cells through up-regulating expressions of ErbB3 protein.

Objective: To analyze the spatial-temporal characteristics of other infectious diarrhea (OID) in Jiangsu province from 2010 to 2017, and to provide evidence for setting up prevention and control programs of the disease. Methods: Data was from the Chinese Center for Disease Control and Prevention and the Statistics Bureau of Jiangsu province. Descriptive methods were used to illustrate the epidemiological characteristics of OID from 2010 to 2017. Global autocorrelation statistics method (Moran’s I) was used to detect the spatial autocorrelation of OID, annually. Kulldorff M spatiotemporal scan statistics was used to analyze the spatial-temporal clustering of OID. ArcGIS 10.0 software, SaTScan 9.4 software and Excel 2017 software were also applied. Results: A total of 126 341 OID cases were found in Jiangsu province from 2010 to 2017 with an average annual incidence as 19.96/100 000. Children under five accounted for 55.08% (69 590/126 341) of the total cases. Obvious seasonal backshift with the increasing trends of the OID was noticed. There appeared four areas with high incidence of OID in the whole province, including Wuxi, Suzhou, Yancheng and Xuzhou. OID showed positive spatial autocorrelation at the county level with higher Moran’s I from 0.19 to 0.33 (P<0.01). There appeared four positive clusters, all occurred in the high incidence period of OID, including the cluster area from the intersection areas of Changzhou and Wuxi (RR=7.61, LLR=2 605.80, P<0.01), respectively. Conclusion With the increasing trends and the seasonal backshift of OID cases, pathogen surveillance programs set for those scattered children under five, in clustered regions and epidemic seasons should be strengthened.

Chronic cerebral hypoperfusion leads to white matter injury (WMI), which subsequently causes neurodegeneration and even cognitive impairment. However, due to the lack of treatment specifically for WMI, novel recognized and effective therapeutic strategies are urgently needed. In this study, we found that honokiol and magnolol, two compounds derived from Magnolia officinalis, significantly facilitated the differentiation of primary oligodendrocyte precursor cells (OPCs) into mature oligodendrocytes, with a more prominent effect of the former compound. Moreover, our results demonstrated that honokiol treatment improved myelin injury, induced mature oligodendrocyte protein expression, attenuated cognitive decline, promoted oligodendrocyte regeneration, and inhibited astrocytic activation in the bilateral carotid artery stenosis model. Mechanistically, honokiol increased the phosphorylation of serine/threonine kinase (Akt) and mammalian target of rapamycin (mTOR) by activating cannabinoid receptor 1 during OPC differentiation. Collectively, our study indicates that honokiol might serve as a potential treatment for WMI in chronic cerebral ischemia.
