The purpose of this study was to investigate the prevalence of plasmid-mediated AmpC beta-lactamases in Escherichia coli and Klebsiella pneumoniae from five children's hospitals in China. A total of 494 E. coli and 637 K. pneumoniae isolates were collected from five children's hospitals in China from 2005 to 2006. The isolates with decreased susceptibility to cefoxitin were subjected to confirmation test with 3-aminophenyl boronic acid. Polymerase chain reaction (PCR) amplification of the blaAmpC, blaTEM, blaCTXM, and blaSHV genes and their gene sequencing were performed. Transconjugants were achieved by conjugation experiments. Plasmid-mediated AmpC beta-lactamases were found in 10.1% of K. pneumoniae (64/637) and in 2.0% of E. coli (10/494) strains. The proportion of plasmid-mediated AmpC-producing strains significantly increased from 2005 (2.6%) to 2006 (9.3%) (p<0.001). The DHA-1-producing isolates were the most prevalent type (93.2%, 69/74). The sequences of blaDHA-1 genes were all identical to those from the GenBank. Strains of blaCMY-2 were isolated from five isolates (6.8%), which were all from E. coli. One sequence of blaCMY-2 differs from blaCMY-2 in the GenBank. Eighteen of the 74 (24.3%) AmpC-producing K. pneumoniae and E. coli isolates coproduced an extended-spectrum beta-lactamase (ESBL). Cefoxitin resistance was transferred to 15 of the 74 positive strains (20.3%). Our study has demonstrated the occurrence of plasmid-mediated AmpC beta-lactamases in E. coli and K. pneumoniae in Chinese pediatric patients and DHA-1 type AmpC enzymes had the highest prevalent rate. The CMY-2 AmpC beta-lactamases from the children's hospitals in China in this study are the first reported. Hence, continuous surveillance of the prevalence and evolution of AmpC beta-lactamase is important.

Wide variations were found between the four hospitals studied in the amount and type of antibiotics prescribed although the diseases treated appeared the same. This variation may have been due to differences in disease severity, regional diversity in bacterial resistance or variations in empiric treatment regimens. Despite the introduction of Chinese Ministry of Health Antibiotic Guidelines in 2004, the pattern of antibiotic use in individual hospitals remained unchanged from 2002 to 2006. Antibiotic utilization studies need be taken to the next level; comparing drugs used to treat specific diseases with guideline recommendations. In addition, educational and other interventions to ensure better compliance with guidelines are urgently required.

The incidence of HPIV infection in children is on the rise, particularly following the emergence of SARS-CoV-2, which presents a potential risk to the health of children. Objective: This study aims to investigate the epidemiological and clinical features of human parainfluenza virus (HPIV) in children admitted to Xianyang Children's Hospital (Xianyang Caihong Hospital) from January 2022 to December 2022. Methods: Out of the 5873 cases of hospitalised children, the ones which had HPIV as the only pathogen and were non-standard cases were excluded, and the rest were analysed for their clinical characteristics, based on the six nucleic acids kits used to detect HPIV in respiratory tract viruses. Results: Among 5873 cases of Nasopharyngeal swab specimens, there were 795 cases of HPIV antigen positive, of which 794 cases of HPIV3（13.52%, 3 cases of HPIV1（0.05%; There were 472 males (13.92%) and 325 females (13.09%) in them(χ2 =0.381, P=0.362).The infection rates in spring, summer, autumn and winter were 8.03%, 55.71%, 28.48% and 7.78%, respectively, and the difference of pairwise comparison were statistically significant (χ2=539.158, P=0).There were 318 cases (19.51%) in infant group and 164 cases (10.86%) in children group (χ2=45.118, P=0). With HPIV as the sole pathogen including 363 cases of bronchopneumonia, 237 cases of bronchitis, 8 cases of pertussis syndrome, 84 cases of bronchiolitis. Conclusion: ⑴. During the period of January to December 2022, Xianyang Children's Hospital has seen a high prevalence of HPIV, a virus causing lower respiratory tract infection, especially HPIV3. ⑵.No statistical evidence showed a difference between men and women in terms of high morbidity during spring and summer, which was more common among infants and young children. ⑶. Among children infected with HPIV, the four most common respiratory illnesses are bronchopneumonia, bronchitis, pertussis syndrome, and bronchiolitis. After undergoing symptomatic treatment, most children showed marked improvement. It is imperative to gain a thorough understanding of HPIV infections in children, enabling timely prevention and symptomatic treatment, identifying critical and serious illnesses, and reducing morbidity and mortality.

Background: The management of diabetes-related risk factors could effectively reduce the occurrence of its complications, improve the quality of life of patients, and reduce the mortality of patients. Data analysis based on the eKTANG platform could greatly improve the efficiency of communication between patients and doctors, and strengthen the treatment and management of diabetes. Aim: We created eKTANG to monitor patient health effectively. The eKTANG health management system aims to extensively intervene in blood glucose monitoring, nutrition, exercise, medicine, and health education to enable diabetes patients to achieve optimal treatment results. Methods: Diabetes patients diagnosed by Henan University Medical School included through the eKTANG platform were randomly divided into three groups: member service package group, discharge/outpatient follow-up group, and out-of-hospital care group. We conducted intensive out-of-hospital interventions for three groups of patients for three months to help patients formulate precise blood glucose control plans and conduct training. The traditional group was compared with the eKTANG platform group, and the physiological indicators and patient compliance of the four groups were observed 6 months later. Results: In the eKTANG platform management group, the average blood glucose compliance rate increased significantly, and the percentage of average blood glucose in the range of 3.9-10.0 showed an upward trend. Fasting blood glucose and postprandial blood glucose showed a downward trend. At the same time, the number of patients per capita blood glucose monitoring showed a significant increase compared with the control group. Conclusion: The establishment of the eKTANG platform can improve the efficiency of patient’s medical treatment, improve their lifestyles, reduce the incidence of patient complications, and build a virtuous circle gradually. This research has strengthened the health management and autonomy of diabetic patients and improved the efficiency of treatment. It is worthy of promotion.
