Vaspin,a serine protease inhibitor derived from visceral adipose tissue,has been identified as an adipokine with insulin-sensitizing effects in a rat model of type 2 diabetes.Recent studies showed that the administration of recombinant human vaspin significantly improved insulin sensitivity and glucose tolerance,and reversed the expression of genes that may promote insulin resistance in diet-induced obese mice.However,the regulation of serum vaspin concentration in individuals with insulin resistance,and the association of vaspin with obesity,type 2 diabetes,and insulin resistance related disorders remain unclear.

Betatrophin,discovered in 2013,is a protein secreted by liver,white adipose tissues,and brown adipose tissues.Betatrophin can improve glucose tolerance in mice by promoting islet β cell proliferation and increasing the number of β cells significantly and specifically.At the same time,Betatrophin is involved in lipid metabolism.Betatrophin may work as the new target for treatment of diabetes and disorders of lipid metabolism.

However the IgG 2 content was lower after the treatment and that of control (P

Objective Esophageal spindle cell carcinoma is a rare type of esophageal squamous cell carcinoma , which was usually named esophageal carcinosarcoma .This article was to discuss the clinical characteristics , treatment and prognostic factors of e-sophageal spindle cell carcinoma . Methods The clinical and pathological data of 28 cases of esophageal spindle cell carcinoma were retrospectively analyzed .The prognostic factors was analyzed for various factors including gender , age, smoking history , tumor loca-tion, tumor size, lymph node metastasis, histological type, pathological staging and adjuvant treatment regimen .Kaplan-Meier method was applied to calculate the survival rate , log rank method for single prognostic factor analysis and Cox proportional hazard regression model for multivariate analysis of prognosis . Results One-year, three-year, and five-year survival rates were 89.3%(25/28), 67.1%(19/28), 38.5%(10/28)respectively.Single factor analysis showed that the pathological type , N stage, T stage, pTNM stage were the factors influencing the prognosis(P﹤0.05), while gender, age, smoking and drinking history, tumor location, tumor size, operation incision selection , adjuvant treatment regimen were not .Multivariate analysis showed pTNM stage were the independent fac-tors affecting the prognosis of esophageal spindle cell carcinoma (χ2 =13.104, P=0.000). Conclusion Esophageal spindle cell carcinoma is a rare kind of esophageal squamous cell carcinoma with less invasiveness , low rate of lymph node metastasis and good progno-sis.Radical operation is the preferred treatment .

In order to investigate the effects of aconitine on [Ca2+] oscillation patterns in cultured myocytes of neonatal rats, fluorescent Ca2+ indicator Fluo-4 NW and laser scanning confocal microscope (LSCM) were used to detect the real-time changes of [Ca2+] oscillation patterns in the cultured myocytes before and after aconitine (1.0 micromol/L) incubation or antiarrhythmic peptide (AAP) and aconitine co-incubation. The results showed under control conditions, [Ca2+] oscillations were irregular but relatively stable, occasionally accompanied by small calcium sparks. After incubation of the cultures with aconitine, high frequency [Ca2+] oscillations emerged in both nuclear and cytoplasmic regions, whereas typical calcium sparks disappeared and the average [Ca2+] in the cytoplasm of the cardiomyocyte did not change significantly. In AAP-treated cultures, intracellular [Ca2+] oscillation also changed, with periodic frequency, increased amplitudes and prolonged duration of calcium sparks. These patterns were not altered significantly by subsequent aconitine incubation. The basal value of [Ca2+] in nuclear region was higher than that in the cytoplasmic region. In the presence or absence of drugs, the [Ca2+] oscillated synchronously in both the nuclear and cytoplasmic regions of the same cardiomyocyte. It was concluded that although oscillating strenuously at high frequency, the average [Ca2+] in the cytoplasm of cardiomyocyte did not change significantly after aconitine incubation, compared to the controls. The observations indicate that aconitine induces the changes in [Ca2+] oscillation frequency other than the Ca2+ overload.

Aconltium plants are a group of important poisonous plants in the Ranunculaeeae family of Angiosperm subphylum.and one of the earliest recorded poisonous plants in China as well.In their tubers(root)have hypertoxic Aconitium alkaloids,which belong to the group of diesterditerpene alkaloids.It is repeatedly reported in China that aconitine poisoning,and even death from aconitine poisoning,caused by the individual differences in pharmaceutical tolerance of aconitine,taking the wrong medicine or inadequate dosage,or put in the poison by homicide.At present,the research on aconitine is mainly limited to clinical treatment,but lack of research on toxicity mechanism of aeonitine.This paper reviews some progress relating to the toxicological mechanisms of this kind of alkaloid.

Objective To investigate the differences of EUS images between stromal tumors and leiomyoma in esophagus and cardia. Methods EUS image of 13 cases of stromal tumors and 11 cases of leiomyoma diagnozed immunohistochemically were collected. Information of gray scale including mean value and dissociation of lesions and submucosal layer were analyzed. Gray scale values of lesions were calibrated according to that of the submucosal layer. Results The mean value of corrected gray scale of stromal tumors was 0. 285, which was significantly different from that of leiomyoma (0. 185, P ＜ 0. 05). Dissociation of gray scale of stromal tumors was 8. 14, which was also significantly different from that of leiomyomia (4. 59,P ＜0. 05). Conclusion In esophagus and cardia, stromal tumors exhibits higher and more inhomogeneous ultrasound echo than leiomyoma.
