Objective To analyze outcome of pulmonary tuberculosis(TB) patients in different household in Shenzhen in 2008, and provide scientific basis for development of TB control strategy. Methods The data from monthly,quarterly,annual report as well as the TB report card and other related information were collected and analyzed. Results A total of 4 826 active pulmonary tuberculosis patients were found in 2008, in which 86.0% were mobile population;2 349 cases of new smear positive pulmonary tuberculosis patients were found;Mobile population cure rate of new smear positive(75.0%) was significantly lower than that of household population(P＜0.01). Mobile population moving out or loss rate of new smear positive(13.5%) was significantly higher than that of household population(P＜0.01). Conclusion Mobile population cure rate of new smear positive was lower and moving out or loss rate of new smear positive(13.5%) was higher. Mobile population TB control in Shenzhen was the key and difficult.

Objective To understand the situation of drug resistance( DR) and multi-drug resistance( MDRTB) tuberculosis in Shenzhen and provide scientific evidence for TB control in Shenzhen. Methods According to drug resistance TB guidelines issued by WHO/IUALD, all new smear positive cases and.new registered retreatment smear positive cases in 2005 and 2009 were included in the surveillance. A total of 1856 strains of mycobacterium tuberculosis were isolated and drug susceptibility test were performed with the proportional method. Results In 2005, the overall DR rate was 18. 3% , 17. 2% and 31. 3% for initial and acquired DR respectively, overall MDR rate was 4. 74% ,3.25% and 21.9% respectively for initial and acquired MDR. In 2009, the overall DR rate was 17.4% , 16% and 39. 3%for initial and acquired DR respectively,overall MDR rate was 3.8% ,3.02% and 16.4% respectively for initial and acquired MDR. In 2005,2009, the rates of acquired DR and acquired MDR were significantly higher than the rates of initial DR and initial MDR. Conclusion The incidence of TB drug resistance in Shenzhen was high and merits attention.

Objective To separate and cultivate homo umbilical cord blood (UCB) hematopoietic stem cell (HSC) in vitro, and u-tilize bone marrow desmohemoblast stem cell as trophoblastic layer combined with cytokine to amplify umbilical cord blood hematopoietic stem/progenitor cell. Methods Ficoll lymph-cell separating medium density gradient centrifugalization was used to segregate UCBHSC.Bone marrow desmohemoblast stem ceil and cytokine were added, and the sum of NC cells and CD34 + cells was counted. Results The sum of NC cells amplified 75.2±15.0 times, and the sum of CD 34 + cells amplified 18.7±12.3 times. Conclusions It has significant effect on amplification of hematopoietic stem cell with bone marrow desmohemoblast stem cell and eytokine when HSC are cultured in vitro.

Objective To assess the value of serum amyloid A (SAA) in patients with acute asthma attack. Methods Sixty-four asthmatic patients in acute phase and 20 healthy individuals were included. The asthmatic patients were divided into bacterial infection-induced group and non-bacterial infection-induced group. Lung function test and chest X-rays test were conducted And inflammatory cell counts , serum SAA and CRP levels were measured. SAA were compared among subgroups of asthmatic patients and healthy controls and the diagnostic value of SAA to distinguish bacterial infection-induced asthma was estimated. Results SAA of both asthma subgroups were significantly higher when compared with the healthy individuals, and it was higher in bacterial infection-induced group than that in non-bacterial infection-induced group. In terms of ROC curve , AUC was 0.966 for SAA to distinguish merging bacterium infection, and the cut-off value was 36.67mg/L with sensitivity of 92.3% and specificity of 88.2%. Conclusions SAA increases in patients during acute asthma attack, and particularlymore obviously in bacterial infection-induced patients. It may be used as a reliable biomarker to distinguish merging bacterium infection during acute asthma attack.

This article mainly expounded the actuality,the importance and the improving way of enhancing the western rural education.

Objective To study the feasibility of using heat and moisture exchangers (HME)as an alternative to heated humidifiers (HH) in patients undergoing mechanical ventilation. Methods 266 pa-tients with mechanical ventilation admitted to our ICU over the recent 3 years were allocated to the experi-mental group (humidification with a heat and moisture exchanger) and the control group (with heated hu-midifier), and the effect of humidification, the reserved time of artificial airway, the time on mechanical yen-tilation, the time of stay in ICU, the ineidenee of ventilator-associated pneumonia (VAP) and the mor-tality rate were comparatively studied and analyzed. Results Significant differences were found between the experimental and the control group in effect of humidification, insufficiency of humidification or excessive hu-midification, airway spasm and time on mechanical ventilation and time of stay in ICU. The incidence of VAP in the control group was significantly higher than that in the experimental group. There were no significant dif-ference between the two groups in the reserved time of artificial airway and the mortality rate. There were no accident of humidification occurred in the experimental group while there were one case complicated with air-way burn and 11 eases complicated with choking with water in the control group. Conclusions We conclude that HH can be replaced by HME on mechanical ventilation while disease evolution and effect of humidification should be monitored closely and keep HME unobstructed.

OBJECTIVE: Explore the model of universal NICU newborns' hearing screening in high-risk neonates, preliminary understanding factor of hearing damage. METHOD: Transient evoked otoacoustic emissions (TEOAE) and automatic auditory brainstem response (AABR) were used to detect newborns' hearing in 13 315 objects, that is newborns' hearing screening in NICU with TEOAE test who not pass, 42 days after will use AABR rescreening. Children's Hearing Center of Guangxi Child Health Hospital will diagnose the newborns that did not pass in 3 months. RESULT: In these 13 315 newborns, 5 151 subjects who did not pass the initial screening, 1910 subjects who also did not pass after 42 days, 1167 subjects cannot pass the rescreening after 3 months, 642 subjects were diagnosed congenital hearing impairment by Brainstem Auditory Evoked Potential Test, the rate is 4.82%. CONCLUSION TEOAE and AABR are the suitable model of universal newborns' hearing screening in high-risk neonates.

Spillage of cyst contents during surgical operation is the major cause of recurrence after hydatid cyst surgery. Instillation of a scolicidal agent into a hepatic hydatid cyst is the most commonly employed measure to prevent this complication. SB202190 is a pyridinyl imidazole derivative and is known to be a specific inhibitor of p38 MAPK. In the present study, the scolicidal effect of SB202190 was investigated. Freshly isolated Echinococcus granulosus protoscolices were subjected to SB202190 treatment (10, 20, 40, and 80 microM), and the effects on parasite viability were monitored by trypan blue staining. Corresponding effects were visualized by scanning and transmission electron microscopy. Dose-dependent protoscolex death within a few days of SB202190 treatment was observed. Although the in vitro scolicidal effect of SB202190 was satisfactory, the in vivo efficacy of this drug and also possible side effects remain to be further investigated.
