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:To observe the clinical effect of needling gluteus medius muscle trigger point (TrP) plus chiropractic for sacroiliac joint subluxation.Methods:A total of 124 cases conforming to the inclusion criteria of sacroiliac joint subluxation were classified by anterior subluxation and posterior subluxation,and randomized into a TrP group and a conventional group respectively.There were 63 patients with anterior subluxation who were randomized into a TrP group of 32 cases (including 4 dropped out cases) and a conventional group of 31 cases (including 3 dropped out cases);and 61 patients with posterior subluxation who were randomized into a TrP group of 31 cases (including 3 dropped out cases) and a conventional group of 30 cases (including 3 dropped out cases).Patients in the TrP group received the treatment of needling gluteus medius muscle TrP plus chiropractic,while patients in the conventional group received conventional acupuncture treatment plus chiropractic.The treatment was done twice a week for a succession of 8 weeks.Then,the pain visual analog scale (VAS),Oswestry disability index (ODI) and therapeutic efficacy were evaluated.Results:After treatment,the total effective rate of TrP group with anterior subluxation was 96.9％,higher than 77.4％ in the conventional group,the difference showed a statistical significance (P＜0.05);the total effective rate was 93.5％ in the TrP group with posterior subluxation,higher than 73.3％ in the conventional group.After treatment,the VAS and ODI scores in both groups dropped obviously,the differences showed statistical significance (all P＜0.05);the scores of VAS and ODI in the TrP group were obviously lower than those in the conventional group (all P＜0.05).Conclusion:Needling gluteus medius muscle TrP plus chiropractic had a better therapeutic effect than conventional acupuncture plus chiropractic for sacroiliac joint subluxation.

Objective: To establish an animal model for research of maxillary protraction. Methods: 16 pubertal rabbits were assigned randomly to 2 groups. Titanium bone markers were fixed on each side of mucogingival junction, 1 cm above incisor teeth. The experimental group underwent maxillary protraction by self-made distraction devices. A down and forward elastic force (about 3.43 N) was exerted for 30 days. Results: In 30 d, the distance of premaxilla movement in the experimental group was 1.89 mm averagely, while that in the control group was only 0.11 mm. Cephalometric analysis indicated that the maxilla of rabbits was moved forward obviously by appliance in the experimental group, and maxilla was not rotated. There was no obvious difference between the control and the experimental groups. Conclusion: Animal model used in this experiment for maxillary protraction is reliable. The appliance can move the rabbits maxilla forward obviously during the maxillary protraction.

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 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.

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
