Osteocalcin is a bone matrix noncollagen protein which is one of the most abundant secretory products of osteoblasts. Resent studies have demonstrated that osteocalcin is not only a specific biochemical marker of bone turnover, but also involved in the regulation of energy metabolism. Further studies in the pathophysiological functions of osteocalcin might contribute to the treatment of obesity, diabetes, and metabolic syndrome.

Objective To evaluate the clinical efficacy of submucosal tunnel endoscopic resection (STER) for upper gastrointestinal muscularis propria submucosal tumors (SMTs) with diameter ≥3.5 cm.Methods The clinical data of 14 patients with SMTs≥3.5 cm who were admitted to the Second Xiangya Hospital of Central South University between October 2011 and July 2014 were retrospectively analyzed, including 13 patients with tumor at esophagus and 1 patient with tumor at cardia.All patients underwent STER and the observed indexes included operation tine, tumor location and diameter, results of pathological examination and occurrence of postoperative complications.All patients were followed up regularly at the out-patient department including reexamination of gastroscopy, endoscopic ultrasonography (EUS) and computed tomography (CT) till August 2014.Measurement data with normal distribution were presented as average (range).Results All the 14 patients underwent STER successfully with mean operation time of 83 minutes (range, 60-160 minutes).Fourteen tumors were exited, with 13 located at esophagus and 1 at gastric cardia.En bloc resection was achieved in 13 patients and the tumors were extracted through the tunnel.The tumor in the remaining 1 patient was large with a diameter of 5.3 cm and close to trachea, it was extracted by 2 pieces.The average diameter of 14 tumors extracted was 4.1 cm and postoperative pathological examination confirmed the tumors as leiomyomas.Three patients had postoperative complications, subcutaneous emphysema occurred in 1 patient and retrosternal pain in 1 patient.One patient suffered mucosal laceration and recovered after a metal stent was inserted for 2 weeks.The average duration of postoperative hospital stay was 6.4 days (range, 4.0-8.0 days).All patients were followed up for a median time of 11.5 months (range, 1.0-24.0 months) with no recurrence.Conclusion STER is a safe and effective method for SMTs with diameter≥3.5 cm.

Objectives To investigate the effects of ethanol on neural development and kainate receptor expression in young mice. Methods Fetal alcohol spectrum disorder model was established by administration of 20% ethanol solu?tion to 7-day-old Kunming mice and control animals received physiological saline (The number of treatment and control were 80 and 40, respectively ). Body weight and general biological features were observed every day. Morris water maze was used to test learning and memory ability. Fluoro-Jade B was used to examine neural cells 24 hours after treatment in additional thirty 7-day-old Kunming mice which were further divided into two groups:a treatment group receiving 20%ethanol solution (n=15) and a control group receiving physiological saline (n=15). The development of neural cells and expression levels of kainite receptors were examined by using immunofluorescence staining. Results The body weight was significantly lighter in treatment group than in control group(control:21.13 ± 1.72g,treatment:13.96 ± 2.98g,P<0.05). Morris test showed that model group had longer latency than control group to find hidden platform(control:21.05± 5.31s,treatment:34.15±3.26s,P<0.05). Spatial probe test revealed that the number of passing through the platform were significantly smaller in model group than in control group(control:2.70 ± 1.25 times,treatment:0.93 ± 0.80 times,P<0.05). Astrocyte development anomaly was evident after ethanol treatment for 7 days. The expression levels of kainite re?ceptor GluR-6 and KA2 were up-regulated in the CA region of the hippocampus after ethanol treatment for 7 days. Con?clusion Kainite receptor GluR-6 and KA2 in CA region of the hippocampus may contribute to ethanol-induced hippo?campal neural development anomaly.

Acute suppurative thyroiditis (AST) is a rare non-specific infectious disease of thyroid gland.The signs and symptoms of AST may mimic those of a variety of noninfectious inflammatory conditions or other anterior neck infectious diseases.AST is a progressive disease and is also potentially life threatening if devoid of prompt diagnosis and proper treatment.Herein,we report a case in order to call attention to the diagnosis and treatment of AST.

To investigate the relationship between serum glutamic acid decarboxylase antibody (GAD-Ab)titer and the first-phase insulin release (1PH)in newly-diagnosed type 2 diabetic patients. 1053 newly-diagnosed type 2 diabetic patients were divided into 3 groups, including 71 individuals with GAD-Ab≥1 U/ml (positive group), 171 individuals with GAD-Ab ranging from 0 to 1 U/ml (negative-1 group), and 811 individuals with GAD-Ab=0 (negative-2 group). IPH was evaluated by arginine stimulation test. In the patients of negative-2, negative-1, and positive groups, the respective values of 1 PH were subsequently decreased significantly (P< 0. 01) , and the detection rates of the decreased insulin secretion were 74. 85%, 87. 13%, and 100%, respectively. Stepwise regression analysis indicated that disease duration, GAD-Ab titer, HbA_1C, and body mass index were the major independent contributing factors. The titer of GAD-Ab has an important impact on 1PH defect in type 2 diabetic patient. Detection of GAD-Ab not only provides an evidence for clinical type, but would also be helpful in determining the islet β-cell function.
