Chinese Journal of Nosocomiology 2004;0(10):-
OBJECTIVE To investigate distribution and drug resistance status of infections in urinary system and offer scientific basis for reasonable usage of antibiotics. METHODS Totally 258 isolates collected from urinary infection specimens were identified and drug susceptibility test was performed. RESULTS Escherichia coli rated the top one,73.3%.The isolates were susceptible to imipenem and amikacin.The resistant rate to other 6 antibiotics were above 50%. CONCLUSIONS The drug resistance rate of isolates collected from urinary infection specimens goes upward,so we should pay attention to.

OBJECTIVE To prevent and control hospital cross-infection and hematogenous disease dissemination during oral cavity procedures.METHODS The problems that existed universally in instrument treating processes during oral cavity procedures were taken seriously.The perfect management rules and regulations were established.The instructions of technical operation were carried out strictly.We strengthened own-self occupation protection and implemented the standard prevention isolation principle.We guaranteed oral cavity synthesis method to implement,such as the instrument cleaning,disinfection,and antiseptic quality.RESULTS The hospital infection occurred in the oral cavity procedures could be reduced and avoided fundamentally through implementing infection control measure.The medical safety could be ensured.CONCLUSIONS The personnel standard diagnosing and treating operation of medical care should be established in hospital.The idea of disinfection and isolation asepsis should be enhanced.Own-self occupation protection must be required strictly.It is extremely important to control the infection during the oral cavity procedures.

Chinese Journal of Nosocomiology 2004;0(10):-
OBJECTIVE To guide the reasonable application of antibiotics. METHODS The isolation and culturing of bacteria were done according to The National Clinical Laboratory Operation Rules. RESULTS The main pathogens from urine were Escherichia coli(49.5%),Enterococcus faecium and E.faecalis,from sputum were Pseudomonas aeruginosa(32.5%),E.coli and Klebsiella pneumoniae,from pus were E.coli,Staphylococcus aureus and coagulase-negative Staphylococcus(CNS),and from blood and prostatic fluid were CNS. CONCLUSIONS Meticillin-resistant CNS(MRCNS) strains are more often seen than meticillin-resistant S.aureus(MRSA) ones,and Vancomycin-resistant Staphylococcus(VRS) strains are not discovered.Staphylococcus are mostly sensitive to vancomycin.E.coli and K.pneumoniae are still sensitive to the first,second,third and fourth generation cephalosporins.

OBJECTIVE To understand the knowledge about nosocomial infection of the personal. METHODS A questionnaire investigation was carried out by the hospital local area network(LAN). RESULTS A total of 202 questionnaires were sent in during one month, and statistic result could be looked up at any moment. CONCLUSIONS Questionnaire investigation via LAN can find the shortcomings of the nosocomial infection management correctly and quickly.

OBJECTIVE To determine the distribution of bacterial flora in hospital infection and to provide laboratory(evidence) for controlling hospital infection and selecting rationally antibiotics in clinic practice.METHODS All(isolates) were identified by routine procedure.MRSA and ESBLs-producing rate of Escherichia coli and Klebsiella pneumoniae were(examined.) RESULTS Among all these clinical infectious specimens,there were 202 strains of Gram negative bacilli,(accounting) for 40.9%(202/495);166 strains of fungi,accounting for 33.5%;621 strains of Gram positive cocci,for 20.6%(102/495).Candida albicans,E.coli,Pseudomonas aerugionosa,C.tropicalis and C.glabrata took the first five bacteria in infection.Analysis of drug resistant bacteria suggested that the isolated rate of ESBLs-producing strains in Staphylococcus aureus be 47.6%,be CNS in MRCNS 78.1% and MRSA in SA be 42.3%.CONCLUSIONS Multidrug resistance and fungus infection are the main risk factors in our hospital.We must improve means of treatment on clinical work and use antibiotic rationally to reduce the infection rate.

OBJECTIVE To analyze risk factors in order to provide scientific gist in diagnosis and treatment of central venous catheter related sepsis(CRS) in patients with total parenteral nutrition(TPN). METHODS To make comparison of the 57 cases of CRS with 423 cases of non-CRS during 1998-2002.First,monovariable chi-square test and then non-condition Logistic regression analysis of the markedly different factors in SPSS10.0 were conducted. RESULTS The major risk factors might be infectious disease,duration of central venous catheter in,location of catheter, type of catheter and material of catheter,and serum protein

OBJECTIVE To define the regularity of survival ability of HIV in natural environment,and prevent(infection) through contacting with positive body fluids during daily life or medical work.METHODS Having been diluted by sterile water or 10% serum RPMI 1640 medium,HIV was exposed to 4℃,room temperature(20-26℃) or 37℃ for different period of time.TCID_(50) of these samples was detected.Non-pathological samples were blind passaged for three generations.RESULTS HIV infective ability persisted more than 35 days both in(water) and medium at 4℃;whereas it persisted 7-14 days in water,14-21 days in medium at room temperature and 37℃.CONCLUSIONS HIV has higher resistance in natural environment.To prevent accidental spreading of HIV,HIV positive liquids and contaminants staffs should be treated carefully.

OBJECTIVE To evaluate the use of antibiotics in general hospitals of Ningbo. METHODS Totally 4 391 case history records in April,2004 of 12 hospitals were investigated on the use of antibiotics. RESULTS Medicines incomes accounted for 55.16% in total revenue in a hospital,and antibiotics accounted for 32.66% among medicines incomes.Antibiotics using rate was 62.11% in internal medicine departments.The percentage of antibiotics using without evidence was 23.92%,the combined antibiotics using rate was 49.89%.The average duration for antibiotics using was 10.83 days.Antibiotics using rate in surgery departments before operation was 71.00%,during operation was 20.48%,the combined antibiotics using rate during operation was 14.50%,antibiotics using rate after operation was 96.55%.Antibiotics using for treatment accounted for 62.37% and for prevention was 24.17%. CONCLUSIONS Antibiotics using rate is high in hospitals in Ningbo.Income of medicine is also an important part of total revenue in a hospital.We should pay more attention to management on clinical use of antibiotics.

OBJECTIVE To study the clinic feature and cause of misdiagnosis of early stage syphilis and evaluate the significance of histopathology in the diagnosis of the disease. METHODS Totally 1 200 early syphilis cases were analyzed.The serologic test for syphilis was performed.Thirty five of them were performed with histopathological examination. RESULTS The primary syphilis was found to be commonly misdiagnosed as chancroid,genital herpes,scabies nodules and ulcus vulvae acutum.For secondary syphilis,macular syphilide and maculopapular syphilide were easily misdiagnosed as pityriasis rosea or dermatitis.The papulosquamous syphilide was commonly misdiagnosed as psoriasis.The condyloma latum was commonly misdiagnosed as condyloma acuminatum. CONCLUSIONS The serologic test is important in diagnosis of primary syphilis.The histopathologic test plays a role in diagnosis of primary syphilis,condyloma latum and papulosquamous syphilide,but of limited value in diagnosis of macular syphilide.
