Fourteen neonatal diabetes mellitus(NDM)patients were recruited. 9 patients were treated with glyburide and the other 5 with insulin. ABCC8, KCNJ11, and INS genes were sequenced in 6 of them. Gene mutations were found in 2, 1, and 1 cases in these genes, respectively. One case with 6q24 hypomethylation and another without known mutation were also found. 8 out of 9 patients treated with glyburide reached euglycemia(88.9%). The other 5 patients with insulin therapy either died or lost contact. The results suggest that glyburide therapy is effective in neonatal diabetes mellitus, while insulin therapy may contribute to poor compliance.

Objective: To study the feasibility of ¹⁸F-fluoro-L-dihydroxyphenylalanine positron emission tomography/Computed tomography (¹⁸F-DOPA PET/CT) scanning in the localization and differential diagnosing of focal versus diffuse form of pancreas lesions in patients with hyperinsulinemic hypoglycemia (HH). Method: Twenty-four patients were diagnosed with HH between January, 2016 and February, 2017 in the Department of Pediatric Endocrinology and Inherited Metabolic Diseases, Children′s Hospital of Fudan University using an integrated clinical and biochemical diagnostic protocol, domestic ¹⁸F-DOPA PET/CT imaging technique were applied after MRI and ultrasound failed to detect pancreas lesions. Pancreas ¹⁸F-DOPA standardized uptake values (SUV) were measured, and pancreas′ lesions were dually analyzed via visual method and pancreas percentage SUV method. Among these patients, 9 patients received surgical pancreatic lesion resections, the correlations among surgical outcomes, histopathological findings and ¹⁸F-DOPA PET/CT scan results were analyzed. Result: Seven patients were detected with focal form of pancreas lesions, the mean peak of SUV was 4.7±1.7(2.6-7.1), and 17 patients were found to have diffuse form lesions after ¹⁸F-DOPA-PET/CT scanning. Among the 24 cases, 9 patients (7 showed focal and 2 showed diffuse ¹⁸F-DOPA PET/CT pancreatic uptake)were euglycemic without any medical support after surgery; the resected pancreatic tissue histopathological results were consistent with that of PET/CT imaging. Only one patient, who responded to medical treatment before surgery, had temporary hyperglycemia after operation. Conclusion Domestic ¹⁸F-DOPA PET/CT could successfully locate and differentiate the pancreatic lesions and thus improve the success of surgery.

Objective To study the infection status of Helicobacter pylori (H. pylori) and sensitivity to commonly used antibiotics in Taizhou district,Zhejiang province. Methods 39 099 cases aged between 5 and 95 years old(mean as 48.42 years)were involved during January 2010 to December,2013 for this study. Sex ratio was 1 ∶ 0.95. Yearly distribution of the number of cases were 5 031,6 709,11 902 and 15 457 in 2010,2011,2012 and 2013,respectively. Gastric mucosal specimens were collected and H. pylori strains were isolated and cultured in the same platform in Zhiyuan Medical Inspection Institute of Hangzhou. Resistance tests of all the H. pylori isolates were performed to 6 commonly used antibiotics:metronidazole,clarithromycin,amoxicillin,gentamicin, levofloxacin and furazolidone with the agar dilution method. The antibiotic resistance rates of H. pylori strains isolated during year 2010-2013 and the changing trends were analyzed. Results Resistance rates to levofloxacin and clarithromycin kept at higher level and the highest was in 2011 and then decreased in both 2012 and 2013 (P<0.01). The resistance rates to both levofloxacin and clarithromycin reached the highest in 2011(P<0.01),and decreased thereafter,with no significant change in 2013 to 2012(P>0.05). Conclusion Antibiotic resistance rate against metronidazole for HP isolate was highest. Resistance rate against amoxicillin and furazolidone,gentamicin was low. Clinical treatment should choose amoxicillin and furazolidone,gentamicin. The resistance rates to levofloxacin and clarithromycin had been seen at a significantly downwarding trend since 2011. However,the combined resistance rates to levofloxacin and clarithromycin did not seem to reduce since 2012.

Objective:To observe the effects of electroacupuncture preconditioning on the autophagy-related pathway protein kinase B (Akt)/mammalian target of rapamycin (mTOR) in myocardial tissue of rats with myocardial ischemia reperfusion injury (MIRI); To investigate the protective mechanism of "Neiguan"(PC 6) on myocardial injury.Methods:Totally 48 SD rats were randomly divided into blank group, sham-operation group, model group and Neiguan group ( n=12 in each group). The Neiguan group was applied to bilateral "Neiguan"(PC 6) by electroacupuncture for 30 min, once daily for consecutive 7 days before model replication. Except in the blank group, the MIRI model was established by ligation of the descending anterior branch of the left coronary artery in the rest groups after the intervention. The histomorphological changes in the myocardium of the rats were observed by HE staining, and the expression levels of Akt, phosphorylated Akt (p-Akt), mTOR and phosphorylated mTOR (p-mTOR) in the myocardium were measured by protein immunoblotting. The ratio of p-Akt/Akt and p-mTOR/mTOR was calculated. Results:In the blank group, the myocardial fibres were arranged regularly and neatly, and no inflammatory cell infiltration or haemorrhage was seen in the interstitium; in the sham-operation group, the arrangement of myocardial fibers was slightly irregular, no rupture was found, and a small amount of myocardial fiber gap was slightly enlarged; in the model group, the distribution of myocardial fibers was disordered, hypertrophic cardiomyocytes increased, some mitochondria were red and swollen or the outer membrane was ruptured, and inflammatory infiltration and hemorrhage were seen in the interstitium; the extent of myocardial lesions in the Neiguan group was less than that in the model group, with a small amount of interstitial hemorrhage and inflammatory cell infiltration. There was no statistical significance in the levels of Akt and mTOR in the myocardial tissues of the rats in each group ( P>0.05); compared with the sham-operation group, the levels of p-Akt, p-mTOR and p-Akt/Akt, p-mTOR/mTOR in the model group decreased ( P<0.01); compared with the model group, the levels of p-Akt, p-mTOR and p-Akt/Akt, p-mTOR/mTOR in the Neiguan group increased ( P<0.01). Conclusion:Electroacupuncture preconditioning may inhibit excessive autophagy by activating the Akt/mTOR pathway in cardiomyocytes of MIRI rats, thereby exerting a protective effect on the myocardium.

Objective To summarize the clinical feature,gene mutations,diagnosis,treatment,and follow-up data of protein-sensitive hypoglycemia,so as to improve the clinical understanding of the disease.Methods Five patients were diagnosed with protein-sensitive hypoglycemia during June in 2015 and December in 2017 from the Department of Pediatric Endocrinology and Inherited Metabolic Diseases,Children's Hospital of Fudan University.Clinical data of 5 cases were summarized,including clinical manifestations,findings of protein sensitivity test,therapy effect and prognosis.The endocrine and metabolic panel was used to investigate the genetic cause of four patients.Related literatures of protein-sensitive hypoglycemia were reviewed,and the phenotypes,genotypes,and therapy effects were summarized.Results Among the 5 patients diagnosed with positive results of protein-sensitive hypoglycemia,three were found to harbor glutamate dehydrogenase 1 (GLUD 1) mutations (c.965G ＞ A,p.R322H:2 cases;c.943C ＞T,p.H315Y:1 case),and another one had complex heterozygous mutations in L-3-hydroxyacyl-CoA dehydrogenase (HADH,c.29G ＞ C,p.R10P;c.89T＞ A,p.V30E).5 patients were euglycemia without any medical support after low protein diet.In 18 literatures retrieved and this study,there were totally 161 cases of protein-sensitive hypoglycemia (149 cases with GLUD1 mutations and 10 cases with HADH mutations).Conclusions When a child was admitted because of hypoglycemia,the diagnosis of protein-sensitive hypoglycemia should be suspected if he or she also had postprandial hypoglycemia,with or without hyperammonemia.Protein sensitivity test is helpful for us to make the diagnosis of protein-sensitive hypoglycemia.

Objective: To investigate the self-reported prevalence, clinical characteristics, complications of allergic rhinitis (AR) and the sensitization of outdoor air pollen allergens in children in the Inner mongolia grassland region. Methods: A multistage, stratified and random clustered sampling with a face-to-face interview survey study in children from 0 to 17 years old was performed together with 10 common allergen skin prick tests (SPT) and measurements of the daily pollen count in 6 regions in the Inner mongolia grassland region from May to August of 2015. SAS 9.4 software was used for data analysis. Results: A total of 2 443 subjects completed the study. The self-reported prevalence of AR was 26.6%. The prevalence of boys was higher than that of girls (28.8% vs 24.3%, χ²=6.157, P<0.05). Subjects from urban areas showed higher prevalence than rural areas (34.7% vs 18.8%, χ²=79.107, P<0.05). There was significant regional difference in the prevalence of AR among the six areas investigated (χ²=221.416, P<0.05). The main clinical symptoms of AR were sneezing (88.2%) and nasal congestion (78.6%). Among combined diseases, asthma accounted for 16.5% (107/650), rhinoconjunctivitis accounted for 47.9% (311/650). The peak season of AR was April and July, with the top SPT positive allergens of Artemisia species and chenopodium in this area. Conclusions The prevalence AR in children in the Inner mongolia grassland region is extremely high. Sneezing is the main clinical symptom. Rhinoconjunctivitis is the most common combined disease. High summer and autumn pollen exposure is the main cause of AR.
