OBJECTIVE To analyze the morbidity,the pathogen and the risk factors of nosocomial infection in department of neurology in our hospital for searching the effective prophylactico-therapeutic measures.METHODS On the basis of investigating the recovery patients in department of neurology in our hospital from Jan 2003 to Dec 2005,we analyzed the morbidity,the infected sites,the difference of the nosocomial infection among underlying diseases,and the high incidence of nosocomial infection induced by invasive examination and cure.RESULTS The morbidity of nosocomial infection in department of neurology was 4.73%,and this was the highest in our hospital.The primary infected sites were the lower respiratory tract,the urinary tract and the upper respiratory tract,and the morbidity of nosocomial infective induced by invasion examination and cure increased obviously.CONCLUSIONS The morbidity of nosocomial infection in department of neurology is obviously above than other departments.Therefore,department of neurology should be emphasized to monitor,control and prevent nosocomial infection in the hospital.

To find a new way to treat patients with ectopic eruption of canine or impaction canine,autogenous transplantation of those teeth was explored and had good results.

Rep78/68 is a kind of nonstructural protein from adeno-associated virus. It inhibits a variety of viruses and tumor transformation. In addition, it has significant effect on the proliferation and metabolism of host cells. In this paper, we reviewed the latest research advances of this protein.

Objective To investigate the diagnostic value of serum soluble transferrin receptor(sTfR) in children with iron deficiency anemia(IDA).Methods Sixty-three children with microcytic hypochromic anemia were divided into IDA and non-IDA(n-IDA)groups,on which sTfR and other iron metabolism related indexes such as serum ferritin(SF) and serum iron(SI) were measured,and(t-test) between groups and analysis of ROC curve were carried out.Results The mean concentration of sTfR in the group of IDA was above normal value and t-test difference was extremely significant compared with n-IDA group(P

BACKGROUND: The increase of the incidence of autoimmune diseases and the autoimmune pathogenesis of vitiligo were reported. OBJECTIVE: We studied the frequency of autoimmune disorders and positivity of antinuclear antibody in Korean vitiligo patients. METHODS: Vitiligo patients (439 patients) and control subjects (197 patients) were interviewed about their history of autoimmune diseases. Laboratory studies including complete blood cell count, urine analysis, blood chemistry, fasting blood sugar, thyroid function test (T3, free T4, TSH), and antinuclear antibody were performed for the screening of autoimmune disorders. RESULTS: The diseases associated with vitiligo were microcytic hypochromic anemia (3.64%), non-insulin dependent diabetes mellitus (2.96%), thyroid disease (3.96%), atrophic gastritis, and alopecia areata. In the control subjects, the associated diseases were microcytic hypochromic anemia (1.62%), non-insulin dependent diabetes mellitus (4.65%), and thyroid disease (3.49%). These results show that the frequency of autoimmune disorders in vitiligo patients is not significantly higher than that in control subjects. Six (54.5%) out of 11 vitiligo patients with thyroid disease were diagnosed as having thyroid disease for the first time. Four (0.91%) out of 438 vitiligo patients showed positive to antinuclear antibody. Positivity of antinuclear antibody was not higher in vitiligo patients than that in control subjects (1.16%). CONCLUSION: Frequency of autoimmune diseases and positive reaction to antinuclear antibody in vitiligo patients were not significantly higher than those in control subjects.

Objective To evaluate the effects of ischemic postconditioning on nuclear factor kappa B (NF-κB) and intercellular adhesion molecule-1 (ICAM-1) expression during lung ischemia-reperfusion (I/R) injury in a dog model of cardiopulmonary bypass (CPB), and further investigate the pulmonary protection induced by ischemic postconditioning and the underlying mechanism.Methods Twelve adult mongrel dogs of both sexes, weighing 12-15 kg, were randomly divided into either CPB group or ischemic postconditioning group (IPO group) using a random number table, with 6 dogs in each group.CPB was established after the chest was opened in dogs anesthetized with pentobarbital sodium.Ischemic postconditioning was induced by 2 cycles of 5 min reperfusion followed by 5 min ischemia immediately after occlusion of the left pulmonary artery was released in group IPO.Before CPB (T1), before occlusion of the artery was released (T2) , and at 2 h after termination of CPB, lung specimens were obtained for examination of pathological changes which were scored (with light microscope) and for determination of the expression of NFκB and ICAM-1 (using Western blot) and wet/dry lung weight ratio (W/D ratio) in left lung tissues.Blood samples were collected from femoral arteries at T1 and T3 for blood gas analysis, and oxygenation index (OI), respiration index (RI) and dynamic lung compliance (Cdyn) were calculated.Results OI and Cdyn were significantly decreased, and RI was increased at T3 , and W/D ratio, pathological scores, and expression of NF-κB and ICAM-1 were increased at T2,3 than at T1 in the two groups.W/D ratio, pathological scores, and expression of NF-κB and ICAM-1 were significantly higher at T3 than at T2 in the two groups.Compared with group CPB, OI and Cdyn were significantly increased, and R1, W/D ratio, pathological scores, and expression of NF-κB and ICAM-1 were decreased at T3 in group IPO.Conclusion Ischemic postconditioning up-regulates the expression of ICAM-1 through inhibiting NF-κB activity, thus reducing lung I/R injury induced by CPB and improving the lung function in dogs.

To detect the expression of the human papilloma virus (HPV) 16 and HPV18 in esophageal squamous cell carcinoma in Minnan area. Methods: Real-time fluorescence quantitative polymerase chain reaction (FQ-PCR) was applied to detect HPV DNA in 100 esophageal carcinoma sample and 100 normal tissues beside the tumor. Results:The positive rates of high-risk HPV 16 and HPV 18 infection in Minnan esophageal carcinoma and in normal tissues beside the tumor were 14.00%, 15.00%and 7.00%, 8.00%, respectively. The positive rates of lymph node and non-lymph node metastases were 40.98%and 10.25%, respectively. These re-sults exhibited statistical significance (P<0.01). HPV 16 and HPV 18 infection was uncorrelated with patient age, pathological type, and tumor grade (P>0.05). Conclusion:HPV16 and HPV 18 infection was correlated to esophageal squamous cell carcinoma in Minnan ar-eas. Such infection may also contribute to the occurrence and development of esophageal squamous cell carcinoma.

Objective To design and develop a quadrature demodulation circuit for detection of ampli-tude and phase information in EIT measurement. Methods A model structure file was built in matlab/simulink using the elements in Ahera DSP Builder and verified by simulated stimulation. Then the model file was convert-ed to VHDL file via Signal Compiler, and the synthesis, adaptation, simulation and hardware implementation were accomplished. Results The simulation and testing results show that the circuit can extract the real and imagi-nary information of the measured signal and it also meets the EIT measuring requirement, with acceptable mea-sure error. Conclusion The demodulation circuit based on DSP Builder can precisely give real and imaginary information of EIT and provides technological support for full-information complex impedance measurement.
