Chinese Journal of Nosocomiology 1994;0(01):-
OBJECTIVE To explore optimal change dressing of the incision of trachea.METHODS Seventy-eight patients were randomly and equally divided into the traditional group and test group.In traditional group,after dressings change with conventional disinfection,the sterile gauze was cut into "E" shape and overlapping covered on the incision of trachea around the trachea cannula from top to bottom and fixed with adhensive plaster.In test group,after dressings change with conventional disinfection,the special sterile drainage was fixed and smoothed around the trachea cannula from left to right(or from right to left).RESULTS In test group,skin incision colonies of patients were significantly lower than that in traditional group(P

Objective: To establish human embryonic kidney(HEK) 293 cell lines that that can stably express the muscle nicotinic acetylcholine receptor(AChR).Methods: The pcDNA3.1 plasmid was constructed and transfected into HEK293 cells with lipofectin,the stable transfectants screened by G418 and the protein expression identified and analyzed by immunohistochemistry.Results: After G418 screening,14 of the transfected cell lines highly expreesed ?-nAchR and 4 showed an obvious expression of ?-nAChR,as demonstrated by the immunohistochemical analysis.Conclusion: HEK293 cell lines stably expressing m-nAChR were constructed successfully.

Command of the JCI standard is conducive to promoting the "Patient-centered" quality management concept awareness and realizing the patient safety objective. To this end, a campaign to stage the hospital quality management system and bottom-up quality activities has been launched. These efforts may help improve the hospital quality management system, covering such aspects as standardized document management, human resource management, normalized diagnosis and therapy management centering on clinical path, clinical nursing service quality, safety management, equipment and facility management, as well as data analysis and quality improvement system. These have been subject to and certified by JCI with a gold medal.

AIM: To study effects and adverse drug reactions of mtrisone in the treatment of patients with severe acute respiratory syndrome. METHODS: The information of the medications in 680 patients with severe acute respiratory syndrome (SARS) in Xiaotangshan Hospital was collected by HIS system and the effects and ADRs of metrisone were staiated. RESULTS: The kinds of drugs of SARS patients who had been cured by metrisone were more than those which were not cured by metrisone. Condition of SARS patients who had been cured by metrisone was more serious than those which were not cured by metrisone. The ADRs rate, blood glucose and leukocyte of SARS patients who had been cured by metrisone are higher than those which were not cured by metrisone while blood K+ is lower. CONCLUSION: The utilization of metrison to SRAS patient should be more cautious to balance the effects and ADRs of metrisone.

Objective:To understand the pathogen distributions of community-acquired pneumonia (CAP) in children, and to provide evidence for clinical diagnosis and treatment.Methods:The hospitalized children with CAP in Shanghai General Hospital, Shanghai Jiao Tong University School of Medicine from January to December 2022 were selected as the research subjects. They were divided into infant group (28 d to less than one year), toddler group (one year to less than three years), preschool age group (three years to less than six years), and school age group (not less than six years) by age. According to the onset season, they were divided into spring group (February to April), summer group (May to July), autumn group (August to October), and winter group (January, November to December). Deep airway sputum samples were collected from all patients for bacterial culture identification. Respiratory viruses (influenza A virus (IVA), influenza B virus (IVB), respiratory syncytial virus (RSV), adenovirus, parainfluenza virus type 1 (PIV1), parainfluenza virus type 2 (PIV2), parainfluenza virus type 3 (PIV3)) were detected using direct immunofluorescence assay. Mycoplasma pneumoniae (MP) DNA was detected using fluorescent quantitative polymerase chain reaction, and particle agglutination was used to detect serum MP antibodies. Statistical analysis was performed using the chi-square test. Results:Among the 397 cases of CAP in children, pathogens were detected in 269 cases, with a positivity rate of 67.8%. A total of 309 pathogens were identified, including 204 strains of MP (66.0%), 60 strains of bacteria (19.4%), 42 strains of viruses (13.6%), and three strains of fungi (1.0%). Staphylococcus aureus (19 strains), Haemophilus influenzae (15 strains) and Streptococcus pneumoniae (five strains) were the predominant bacteria, while RSV (19 strains) and PIV3 (nine strains) were the main viruses. The distribution rates of MP, bacteria, and viruses showed statistically significant differences among different age groups ( χ2=99.82, 24.71 and 17.40, respectively, all P<0.05). MP infection was mainly observed in the preschool age group and school age group, and bacterial infection predominantly occurred in the infant group, and viral infection was most common in the toddler group. Among virus infected patients, RSV was detected in the toddler group and the preschool age group, while three cases of PIV3 cases were found in children over five years old. The distribution differences of MP, bacterial and viral infections between different seasons were statistically significant ( χ2=141.65, 20.44 and 31.87, respectively, all P<0.001), with a higher prevalence in winter. RSV infections demonstrated a clear seasonal trend, with 16 cases of RSV infections occurring in winter and spring. Conclusions:MP is the most frequently detected pathogen in children with CAP. Bacterial infection is the most common pathogen in infants with CAP. RSV is the most common viral pathogen, with infections concentrated in the toddler group and the preschool age group, and prevalence in winter and spring. Attention should be paid to PIV3 pneumonia in children over five years old. Rational drug use should be based on the pathogen spectrum characteristics of different seasons and age groups before selecting empirical treatment combinations.
