OBJECTIVE To probe into the impact factors of the nosocomial respiratory tract infections after the operations with tracheal intubation under general anesthesia in order to establish the prevention and treatment strategies and provide the scientific basis.METHODS By descriptive epidemiological method and case-control study method,80 cases with nosocomial respiratory tract infections in nearly 3 years who had tracheal intubation under general anesthesia were selected,and another 180 patients with non-nosocomial respiratory tract infections with tracheal intubation under general anesthesia were selected as the control.RESULTS The incidence of the nosocomial infections from 5923 patients of the operation with tracheal intubation under general anesthesia from 2005 to 2007 accounted for 10.1%.The incidence of the respiratory tract infections of operations under general anesthesia accounted for 5.25%.The nosocomial respiratory tract infection from the tracheal intubation under general anesthesia toped the list and accounted for 52.0%.It showed seven impact factors on the nosocomial respiratory tract infection after the operation with tracheal intubation under general anesthesia by the multi-factorial Logistic regression,respectively,with significant differences(P1).CONCLUSIONS There are many impact factors that the nosocomial respiratory tract infection(especially lower respiratory tract infection) resulting from the operation with tracheal intubation under general anesthesia.The study shows the main risk factors: age,the complications of the disease,surgical condition,the ventilation time of tracheal intubationunder the anesthesia,post-operative recovery time,smoking status,the time that the operated patients start coughing after the operation.Therefore,the prevention is especially important.

Objective: Our aim was to study the role of telomerase activation in the course of cervical carcinogenesis and progression.Methods:Telomeric repeat amplification protocol(TRAP) assay was used to measure telomerase activity in tissue samples with various cervical conditions:40 with cervical cancer, 50 with cervical intraepithelial neoplasia(CIN), 20 with normal cervice. Results:The positive rate of telomerase activity was 95.0%,44.0%, and 10.0% in cervical cancer, CIN, and normal cervices, respectively, which was significantly higher in cervical cancer than that in CIN and normal cervices, so was that in CIN than that in normal cervices (P<0.01) . The positive rate was 22.2%, 37.5%, and 75.0% in CINⅠ,Ⅱ, and Ⅲ, respectively, which was significantly higher in CINⅢ than that in CIN Ⅱand CINⅠ (P<0.01).Conclusion:Telomerase activation may relate to cervical carcinogenesis, which correlates well with the grade of cervical lesions.

The exact scales of volume and density of human internal organs were measured synchronously with the intelligentized volum-densimeter, which was made. by ourself. These primary values of normal and diffuse pathologic changes can refer easily and used for the diagnosis in human autopsy of pathology and forensic pathology. It is expectated to be co-operated widely in that the basic values of volume and density will be obtained from all organs of the human body with the population of different races. But up to now, we are still lack these primary values in anthropology and medicine.
