OBJECTIVE To investigate the characteristics and risk factors of nosocomial infection(NI) in patients with hematological malignancies(HM),and provide the bases for making the controlling measures of NI.METHODS Using the targeted monitoring to study NI in patients with HM,and recording 14 factors such as the time of hospitalization,chemotherapy,count of leukocyte and absolute neutrophil count(ANC) and so on.The data were analyzed with unifactorial ?2 test and multifactorial Logistic-regression analysis.RESULTS Among 242 patients with HM the prevalence of NI was 35.5%(86/242) and the prevalence of NI time-cases was 52.9%(128/242).Among 86 patients of NI there were 27 patients occurred multiple sites NI(31.4%).The main infection sites were upper respiratory tract,gastrointestinal tract,lower respiratory tract,oral cavity and blood.66.7% Of NI happened in the period of chemotherapy and 7 days after chemotherapy.The time of hospitalization and ANC were independent risk factors of NI in patients with HM.CONCLUSIONS The patients with HM are susceptible population of NI,and NI often occurs in the period of chemotherapy and 7 days after chemotherapy.So medical staff should strengthen monitoring,and shorten the time of patient hospitalization and of recovery of ANC to reduce the prevalence of NI efficiently.

Objective:Deeper studies have been rarely reported on the characteristics and influencing factors of the psychological health of army nurses and on the measures for raising their ability of military stress management. To gain an insight into the psychological state of army nurses in the present military streamlining and to explore its countermeasures. Methods:We investigated the psychological state of 123 army nurses from 6 military hospitals by psychometrical methods and psychological interviews,and analyzed the results. Results:Of the total number of subjects,70.73% scored

Objective To explore the changes of Clara cell secretory protein(CCSP) in asthmatic children and the effects of inhaling glucocorticoid (ICS) on CCSP.Methods Sixty children with asthma were selected as asthma group(in which 39 cases were male and 21 cases were female,aged 3-12 years old) and 30 healthy children were selected as healthy control group(in which 20 cases were male and 10 cases were female,aged 3-12 years old).Venous blood samples were collected in asthma group and healthy control group in morning before breakfast,and then sera were obtained by centrifuge in speed of 1 500 r?min-1 in 10 min.The dynamic levels of CCSP were measured in sera by enzyme-linked immunosorbent assay.Results 1.In asthmatic children,the CCSP levels in acute episode,3 months after ICS,6 months after ICS, and 12 months after ICS[(5.140?2.331)?g?L-1,(8.730?3.392)?g?L-1,(10.510?2.813)?g?L-1]were all lower than that in healthy control group[(13.230?4.010)?g?L-1](Pa0.05).2.Compared with acute episode,the patients who ICS for 3 months,6 months and 12 months had significantly higher levels of CCSP (Pa0.05).Conclusions CCSP may play a protective role in the airway inflammation of asthma.Glucocorticoid may increase CCSP level in asthmatic children.Glucocorticoid and CCSP may cooperate in anti-inflammation in airway of asthmatic children.

AIM:To observe the clinical effect of femtosecond laser assisted penetrating keratoplasty.
METHODS: Twenty-four cases ( 24 eyes ) with corneal lesions were performed with femtosecond laser assisted penetrating keratoplasty. Preoperative and postoperative endothelial cell density and visual quality were compared.RESULTS: One week after operation, corneal grafts were clear in 21 eyes (87. 5%), mild cloudy in 3 eyes (12.5%);visual acuity ≥0. 5 in 18 eyes (75. 0%), 0. 2 ~0.4 in 6 eyes ( 25. 0%). After 3mo the mean corneal astigmatism was 2. 16±0. 21D ( range 2. 25 ~ 3. 09D). Compared to conventional penetrating keratoplasty which mean corneal astigmatism was average 3. 67±0. 38D after operation, there was significant difference between two groups ( P< 0. 05 ). There were significant differences between preoperative and postoperative visual acuity and astigmatism (both P<0. 05).
CONCLUSION: Femtosecond laser assisted penetrating corneal transplantation operation can improve patient's visual quality. And compared to traditional penetrating keratoplasty astigmatism decreased significantly, incision can be made in individual shape more precisely and neatly.

OBJECTIVE By investigating the incidence of nosocomial infection with objective monitoring method and prospective overall monitoring method, to analyze the advantage and significance between two methods. METHODS Using the objective monitoring method to study the incidence of nosocomial infection of patients after neurosurgical operation from May to December in 2003 and using the prospective overall monitoring method to study the incidence of nosocomial infection of patients after neurosurgical operation from May to December in 2002. All data were analyzed with Stata 7.0 soft. RESULTS There were 100 cases occurring nosocomial infection in 267 neurosurgical operation patients. The patient incidence of nosocomial infection was 37.5% and the rate of nosocomial infection cases was 50.9% with objective monitoring method, that was significant higher than those data coming from May to December in 2002 with 248 cases under prospective overall monitoring method, with which the patient incidence of nosocomial infection and the rate of nosocomial infection cases were 20.2%(50 cases ) and 21.4%(53 cases), respectively . Statistically significant difference was found (P
