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 investigate the status quo and influencing factors of social isolation of parents of children with autism spectrum disorder in order to provide theoretical basis for clinical intervention measures.Methods:A total of 340 parents of children with autism spectrum disorder who visited the Children′s Developmental Behavior Center of Third Affiliated Hospital of Sun Yat sen University were selected by the convenience sampling method as research objects during July to November 2023. A cross-sectional survey was investigated by a general information questionnaire, General Alienation Scale, Social Avoidance and Distress Scale, Affiliate Stigma Scale, Family APGAR Index, Chinese Simplified Version of Social Support Scale, and Social Responsiveness Scale.Results:A total of 323 valid questionnaires were collected, including 235 mothers and 88 fathers; 33 individuals aged 25-29 years, 233 individuals aged 30-39 years, and 57 individuals aged 40-60 years. The subjective social isolation score of parents of children with autism spectrum disorder was 33.24 ± 4.92 and the objective social isolation score was 4.00(2.00,7.00). The results of multiple linear regression analysis showed that the subjective social isolation of parents of children with autism spectrum disorder was influenced by factors including self-assessed health status, whether they worked full-time or not, whether they were satisfied with the division of labor in the family caring for their children, affiliate stigma, family care, and social support (all P<0.05); and the objective social isolation of parents was influenced by factors including the severity of autism symptoms, self-assessed health status, affiliate stigma, and family care (all p<0.05). Conclusions:Parents of children with autism spectrum disorder had some degree of social isolation, and the level of subjective social isolation was higher than objective social isolation. Healthcare professionals should pay attention to parents of autistic children who have high levels of symptom severity, poor self-rated health, do not work full-time, and are dissatisfied with the division of labor in the family caring for their child, and take measures to reduce the affiliate stigma, and to increase the level of family care and social support, so as to improve the social isolation of parents of children with autism spectrum disorder.

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 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 summarize the clinical features and therapeutic outcomes of patients with hyperinsulinemic hypoglycemia (HH) auxiliarily diagnosed by 18F-DOPA positron emission tomography (PET) CT scanning. Methods:The clinical data of 123 patients who were diagnosed with hyperinsulinemic hypoglycemia by comprehensive clinical diagnostic procedures in the Department of Pediatric Endocrinology and Inherited Metabolic Diseases, Children′s Hospital of Fudan University between January 2016 and December 2020 were retrospectively analyzed. Clinical data such as gender, age of onset, province, concurrent serum insulin level measured during hypoglycemia, lesion type of pancreas by 18F-DOPA-PET CT scanning, genetic test results, and treatment were collected successively. The clinical features and therapeutic outcomes were compared between patients with focal and diffuse pancreatic lesions. T test, Rank sum test, and χ2 test were used for comparison between groups. Results:A total of 123 patients with hyperinsulinemic hypoglycemia (72 males and 51 females), whose average age of onset was 3 days (ranging from 1 day to 4 860 days), were recruited from 24 provinces. The concurrent serum insulin level was 7.1 (0.4-303.0) mU/L during hypoglycemia. 18F-DOPA-PET CT scanning identified focal lesions in 25.2% (31/123) and diffuse lesions in 74.8% (92/123) of the patients; 64.2% (79/123) of the HH cases were found to have pathogenic gene variants, in which 88.6% (70/79) were found to have K ATP channel related genes (61 in ABCC8 and 9 in KCNJ11 mutations). Thirty-seven patients (17 focal and 20 diffuse) received surgical treatment with a success rate of 67.6% (25/37). The effective rate of diazoxide for children with diffuse type was significantly higher than that of children with focal group (28.3% (26/92) vs. 9.7% (3/31), χ2=10.31, P=0.001). Conclusions:18F-DOPA-PET CT scan can improve the success rate of surgery. Comprehensive diagnosis of the etiology of hyperinsulinemic hypoglycemia by genetic analysis and 18F-DOPA-PET CT scanning can result in better treatment and prognosis.

Objective:To understand the duration of survival and related influencing factors of HIV/AIDS patients in Liuzhou city.Methods:Both life table method and Kaplan-Meier method were used to calculate the average survival time of HIV/AIDS patients aged ≥15 years reported in Liuzhou city from 2008 to 2018. Factors related to the duration of HIV/AIDS patients were analyzed by univariate and multivariate Cox regression models.Results:A total of 14 856 patients with HIV/AIDS were involved in this study and with the average duration of survival time as 98.74 (95 %CI: 97.73-99.75) months. The cumulative survival rates of 1, 3, 5 and 10 years were 77.0%, 72.0%, 68.0%, 61.0% respectively. Results from the multivariate Cox proportional risk regression analysis showed that factors as sex, level of education, age when HIV infection was confirmed, occupation, route of transmission, source of samples, results of the first CD 4 test and antiviral treatment were all related to the duration of survival to the HIV/AIDS patients. Conclusions:Strategies involving early detection of HIV infection, improvement of the CD 4 initial detection rate and early antiviral treatment will help to significantly reduce the risk of death in HIV/AIDS population. Focus should be on male, middle-aged and elderly (over 41 years old), junior high school education or below farmers and migrant worker populations.

OBJECTIVETo study the infection status of Helicobacter pylori (H. pylori) and sensitivity to commonly used antibiotics in Taizhou district,Zhejiang province.
METHODS39 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.
RESULTSResistance 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).
CONCLUSIONAntibiotic 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 downward trend since 2011. However, the combined resistance rates to levofloxacin and clarithromycin did not seem to reduce since 2012.
