To be on the alert on infants with esophageal foreign body, and to pay more attention to the button battery esophageal foreign body, the clinical data of a 12-month-old infant with button battery esophageal foreign body, which was missed diagnosis for up to 4 months, is analyzed. And the related literature is reviewed. An esophagoscopy was carried out to remove the foreign body. A favorable outcome was achieved. When the infants have unexplained gastrointestinal symptoms, we should consider the possibility of an esophageal foreign body. We should pay attention to the button battery due to its highly corrosive to the esophagus. Timely diagnosis, reasonable operation are the keys to cure.

Patients' HR, MAP, SpO2 and ECG changes were recorded at 10min,20min,30min and 40min after injection. Results The HR,MAP,SpO2 levels of group A and SpO2 level of group B had no significant changes. There are significant changes in HR,MAP of group B. Conclusion Penequinine hydrochloride can be used as preoperative medication and it is conducive to the maintenance of cardiovascular stability.

ObjectiveTo explore the genetic impact of TPH1 A218C,MAOA-uVNTR on abnormal frontal lobe of depressed patients and the interactions between the two polymorphisms using the method of genetic imaging.Methods28 patients with major depression and 34 healthy controls which were equal in sex,age,years of education and had negative family history of mental illness were recruited in our study.All paticipants underwent functional Magnetic Resonance Imaging (FMRI) in negative emotion recognition and were divided into different genotypes.Then frontal lobe was extracted as region of interest by WFU software into six subregions-bilateral superior frontal lobe,middle frontal lobe and inferior frontal lobe.ResultsPatients (0.19 ± 0.01 ) and controls (0.15± 0.05 ) with TPH1 AA genotype showed increased activation in left inferior frontal lobe than patients and controls with AC or CC genot.Patients with AA genotype showed increased activation in right inferior frontal gyrus(0.28 ±0.07) than other five groups as well.Patients with MAOA-H genotype showed increased activation in right middle frontal gyrus(0.15 ±0.06),left inferior frontal gyrus(0.18±0.02) than patients and controls with L genotype.Superimposition of TPH1 A218C and MAOA-uVNTR exsited in abnormal function of left inferior frontal gyrus(F=4.98,P =0.047 ).Patients with AA and H genotype showed increased activation in this area significantly than other patient group.ConclusionDifferent genes in serotonin system can affect brain function through a common 5-HT feature.

Objective To search and evaluate the quality of reports of clinical trial studies published in Chinese Pediatric Emergency Medicine according to CONSORT statement.Methods We collected all articles published in Chinese Pediatric Emergency Medicine from January 1,2011 to November 31,2015 through searching the WanFang Database,then evaluated and analyzed clinical trial studies.Results Among all 1317 articles we retrieved,62 (4.7％)of them belong to clinical trial study.According to CONSORT statement,all the articles satisfied items from 1b to 6b (including abstract,introduction,trial design,participants,interventions and outcomes),only 30(48.4％) and 4(6.5％) articles mentioned item 8a (method used to generate the random allocation sequence)and 8b(type of randomization;details of any restriction),respectively.None of the editors reported item 9(mechanism used to implement the random allocation sequence,describing any steps taken to conceal the sequence until interventions were assigned)and 10(who generated the random allocation sequence,who enrolled participants,and who assigned participants to interventions).Among 62 included studies,33(53.2％)studies concentrated on respiratory system diseases.However,studies about nervous system,circulatory system and digestive system were 5(8.1％),4(6.5％)and 4 (6.5％) respectively.Although all the results had statistical significance,only 38(61.3％),7(11.3％) and 5 (8.1％)mentioned randomization,follow-up and blinding respectively.Flow diagram was only included in one (1.6％) article.Conclusion The articles of clinical trial studies published in Chinese Pediatric Emergency Medicine did not take CONSORT statement as reference completely.

BACKGROUND:It is discovered recently that miRNA is a new regulator that is able to have an impact on gene expression and miRNA contributes to proliferation, differentiation and self-renewal of pluripotent stem cels.
OBJECTIVE:To investigate the mechanism by which miR-155 regulates chondrogenic differentiation of bone marrow mesenchymal stem cels.
METHODS: Sixty healthy Sprague-Dawley aged 12 weeks were randomized into study group and control group, with 30 in each group. Under anesthesia, rats were sacrificed to harvest bone marrow of the lower limbs. Then bone marrow mesenchymal stem cels were isolated, cultured, and transfected with miR-155 mimics in the study group and a negative control sequence in the control group. After chondrogenic induction, RT-PCR was used to detect the expressions of Sox9, Colagen II, Aggrecan and Colagen X gene, and western blot assay to detect the expression of Sox9 and Runx2 proteins.
RESULTS AND CONCLUSION:Compared with the control group, the mRNA expressions of Sox9, Colagen II and Aggrecan were higher, but the mRNA expression of Colagen X was lower in the study group (P < 0.05); the protein expression of Sox9 was higher, but the protein expression of Runx2 was lower in the study group (P < 0.05). These findings indicate that miR-155 promotes the chondrogenic differentiation of bone marrow mesenchymal stem cels and moreover, it can suppress the hypertrophy trend of bone marrow mesenchymal stem cels differentiating into chondrocytes.

Objective To construct adenovirus vector with agiostatinK1-5 gene and to investigate the function of suppression to proliferation and migration for vascular endothelial cells.Methods With the use of gene recombination and clone technology, we constructed the adenovirus vector with the gene of angiostatin K1-5. In vitro vascular endothelial eclls proliferation assay and migration activity were performed through direct infection,MTT and transwell chemotaxis assay. Results 50% TCID indicated that the condence of resultant viruses was 1.5?109PFU/mL. It was purified by CsCL banding,final yield were generally 1.1?1010 PFU/mL plaquing-forming units. Through indirect infect assay and MTT, we found angiostatin K1-5 inhibited human vascular endothelial cells proliferation. We utilized human vascular endothelial cells to study the effect angiostatin K1-5 on cell migration,the result showed that adenoviruse vector with angiostatin K1-5 significantly inhibited HUVEC migration.Conclusion We successfully constructed adenoviruse vector with angiostatin K1-5 and demonstrated its inhibitory effect on proliferation andmigration of HUVEC.

Objective To summarize the clinical experience in Da Vinci surgical system-assisted hepatopancreatobiliary surgery.Methods From January to December in 2009,94 patients with hepatopancreatobiliary diseases were treated at General Hospital of Second Artillery of PLA.The surgical procedure and postoperative recovery of patients were analysed.Results A total of 90 patients had successfully undergone robotic surgery,and 4 patients were converted to open surgery with the conversion rate of 4%(4/94).Sixteen patients received surgeries for hepatic diseases,and 1 patient with a giant hemangioma in the right posterior hepatic lobe was converted to open surgery,because a very close relationship between the hemangioma and inferior vena cava was observed;27 patients received surgeries for hilar diseases;19 patients underwent surgeries for pancreatic diseases,and 3 patients were converted to open surgery,including 2 with poor exposure of the giant pancreatic head carcinoma and 1 with tumors in the distal common bile duct:32 patients received other surgeries,including 6 with choledochojejunostomy and 11 with laparoscopic common bile duct exploration.Conclusions Almost all kinds of operations for hepatopanereatobiliary diseases could be performed by Da Vinci surgical system.Da Vinci surgical system expands the indications for laparoscopic surgery.
