ObjectiveTo systematically review the methodological quality of guidelines on the management of bronchiolitis in children, then to compare the recommendations and to provide a reference for clinical use. MethodsGuidelines concerning bronchiolitis were electronically retrieved in CNKI, VIP, WanFang Data, CBM, PubMed, EMbase, Medlive, GIN (Guidelines International Network), CGC (China Guideline Chearinghouse), NGC (National Guideline Clearinghouse), AAP (American Academy of Pediatrics), NICE (National Institute for Health and Clinical Excellence) and WHO (World Health Organization) from inception to December 2015. The methodological quality of included guidelines were evaluated according to the AGREE II instrument, and the differences between recommendations were compared. ResultsEight guidelines on bronchiolitis were included, Among them, one guideline was developed by UK, two by US, one by Spain, two by Australia, one by Scottish and one by South Africa. Five of them were evidence-based (EB) guidelines, and 3 were non-EB guidelines. Domain 4 (clarity of presentation) showed the highest scores (81%), then scope and purpose (74%), stakeholder involvement (56%), rigor of development (52%), editorial independence (43%), and scores (42%) were the lowest in domain 3 (applicability). The recommendations of managements and medicines for bronchiolitis were basically consistent, but there were individual differences suggested. ConclusionIn these guidelines, the domain score better is "clarity of presentation" and "scope and purpose ", but the other areas should need to improve. Current our country only has an expert consensus of bronchiolitis, which should be further improved. It's urgent to develop evidence-based guidelines which conforms to the situation of our country, in order to make evidence-based medicine implementation in clinical practice.
Objective To investigate the reliability of culture method of adult human parathyroid cells. Methods Adult human parathyroid tissue was digested by collagenase, then the original generation of cells were cultured and passaged, and their morphological changes were observed and recorded every other day. Part of the passaged cells were observed through electron microscope and its supernatant parathyroid hormone (PTH) was assayed. Meanwhile, the other part of cells were tested the parathyroid markers, including PTH, calcium-sensing receptor (CaSR) and glial cells missing-2 (GCM-2) by PCR. Results Abundant cytoplasm, mitochondria, endoplasmic reticulum and Golgi apparatus from the seventh day's passaged cells were observed by the electron microscopy, as well as, some secretory granules existing in both cytoplasm and intercellular lacuna. Also, the PTH from supernate was detected, and parathyroid specific markers, such as CaSR, PTH, and GCM2 were positive. Conclusions These trials demonstrated the adult human parathyroid cells could be harvested by collagenase digestion and the cultured. Furthermore, the cells remained good shape and kept functioning, making it a potential source for allogeneic cell transplantation to the treatment of permanent hypoparathyroidism.
ObjectiveTo know the situation of nosocomial infection in 2014 in a western region hospital, in order to provide a scientific basis for hospital infection control and management. MethodWe selected the patients on August 14th in 2014 during the time from 00:00 to 24:00 as our study subjects. Bedside investigation and medical records investigation were combined to study the cross-sectional survey of nosocomial infection. We completed the questionnaire, and used statistical methods to count related data about nosocomial infections and community-acquired infections. ResultsA total of 1 908 patients were investigated. The nosocomial infection prevalence rate was 4.45%, and the community-acquired infection prevalence rate was 29.09%. The highest prevalence of nosocomial infection department was the Intensive Care Unit (38.10%); the top three surgical systems were Thoracic Surgery (18.67%), General Surgery (16.67%), and Neurosurgery (10.53%), and the top three medical systems were Endocrinology (11.11%), Neurology (6.67%), and Infectious Diseases Department (5.88%). The top three community-acquired infections occurred in Pediatrics Department (non-neonatal group) (95.37%), Burn surgery (92.31%), and Respiratory Medicine (86.46%). The main infection site for both nosocomial and community-acquired infection was lower respiratory tract (58.24%). Pathogens were mainly Escherichia coli, Klebsiella pneumoniae, Acinetobacter baumannii, Staphylococcus aureus, and Pseudomonas aeruginosa. Hospital and community-acquired infection bacterial spectrum were consistent. And the rate of antibiotics use was 40.82%, in which 126 patients used for prevention (6.60%), and 599 patients used for treatment (31.39%). For patients using the drugs for treatment, bacterial culture submission rate was 80.71%, and the positive rate was 43.78%. ConclusionsThe prevalence of nosocomial infection is reliable, which provides a data support for nosocomial infection prevention and control.
