To evaluate the charasteristics and risk factors of hospital infections in patients with contagious diseases, 489 patients with contagious diseases were analyzed. Among 18 patients who contracted hospital infections, 17 were suffering from chronic hepatitis. 77 78% of them were over 40 years old. Infection of ascitic fluid, lower respiratory tract, and blood stream comprised 77 78% of the infections. Most of the doctors used antibiotics empirically. The survey showed that patients over 40 years old in an infectious diseases hospital were vulnerable to hospital infections. Hospital infection often occurred in the abdomen, lower respiratory tract, and blood stream. Abdominal paracentesis liver puncture biopsy, and lumbar puncture were the first three exogenous risk factors.

0.05).Conclusions Serum NT-proBNP level is sensitive and specific for the diagnosis of pneumonia complicated with CHF and CHD complicated with CHF. There is an increasing tendency of NT-proBNP level companied increasing pulmonary pressure.

ObjectiveTo investigate the effects of sevoflurane on inhibition of invasive activity and migration of human adenocarcinoma cell line A549 by cisplatin.MethodsThe.human lung adenocarcinoma cell line A549 was obtained from Shanghai Cell Biology Institute,Chinese Academy of Sciences and cultured in RPMI 1640 culture medium containing 10％ fetal calf serum.The cells were inoculated in culture plate and cultured for 24 h and randomly divided into 4 groups:control group; 2.5 ％ sevoflurane group ; cisplatin group and cisplatin + 2.5 ％sevoflurane group.In groups sevoflurane,cisplatin and cisplatin + sevoflurane the cells were exposed to 2.5％sevoflurane or/and cisplatin 10μmol/L for 4 h respectively.The invasive activity of the cells was evaluated by Transwell chamber assay.The migration of the cells was determined by wound healing assay.The expression of MMP-2,MMP-9,Ezrin,and Fascin in the cells was detected by Western blot.ResultsBoth 2.5％ sevoflurane and cisplatin depressed invasive activity and migration of the A549 cells and down-regulated MMP-2,MMP-9,Ezrin and Fascin expression in A549 cells.The inhibitory effects of cisplatin on the A549 cells were potentiated by 2.5 ％ sevoflurane.ConclusionSevoflurane can enhance the inhibition of invasive activity and migration of human adenocarcinoma cell line A549 by cisplatin.

Objective To explore the mechanism of tripterygium wilfordii hook f(TWHF)for Henoch-Schonlein purpura nephritis(HSPN,nephrotic type)in children.Methods All the children with HSPN(nephrotic type)were divided into 3 groups casually.Method of radioactive pairs conjugating analysis was used to determine the numbers of glucocorticoid(GC)receptors(GCRs).Results were statistically analysed respectively.Results GCRs tested in all the patients with HSPN(nephrotic type)before treatment were statistically lower than those in control group of normal children;GCRs in all the patients tested after 1 week treatment with GC were lower than before treatment.Three weeks later,GCRs in patients treated with TWHF increased much higher than them without TWHF.Following up the recurring times of all the patients 3 months to 5 years,they were much more in patients treated without TWHF treatment than in patients treated with it.Conclusions TWHF treatment on HSPN(nephrotic type)is obviously effective.It can not only decrease the dosage of GC,but decrease the recurring times.One of the mechanism may be TWHF can resist the down-regulation GC to GCR,and enhance the effect of GC.

Objective To investigate the effects of isoflurane and sevonumne on apoptosis and expression of CD44 and CD54 in human lung cancer cell line A549.Methods Human lung cancer A549 cells were obtained from Shanghai Cell Biology Medical Research Institute,Chinese Academy of Sciences,and inoculated in 24 well culture plate.After being cultured for 24 h the cells were randomly divided into 3 groups:group Ⅰ control(group C);group Ⅱ isoflurane (group Iso) and group Ⅲ sevoflurane (group Sev).A 549 cells were exposed to 1.7% isoflurane and 2.5%sevoflurane for 4 h respectively in group Iso and Sev respectively,and were then cultured for another 24 h.Apoptosis and expression of CD44 and CD54 in A549 cells were detected with flow cytometer at 0 (T0),2 h(T1) and 4 h(T2) of and 24 h after(T3) exposure to isoflurane and sevoflurane.Results The percentage of apoptotic cells wag significantly higher at T2 and T3 in group Iso than in group C.The percentage of apoptotic cells was significantly higher at T1,T2 and T3 in group Sev than in group Iso and C.The expression of CD44 and CD54 at T1,T2 and T3 was significantly decreased as compared with the baseline at T0 in group Iso and Sev and was significantly lower in group Iso and Sev than in group C.Conclusion Isoflurane and sevoflurane can induce apoptesis of human lung cancer cell line A549, and sevoflurane is more effective. Isoflurane and sevoflurane can inhibit the expression of CD44 and CD54 of human lung cancer cell line A549.

Objective To investigate the effects of different concentrations of sevoflurane on Survivin expression in human adenocarcinoma cell line A549. Methods A549 cells were obtained from Shanghai Cell Biology Medical Research Institute, Chinese Academy of Sciences and inoculated in 96 well culture plate. After being cultured for 24 h, the cells were randomly divided into 4 groups: Ⅰ , Ⅱ , Ⅲ and Ⅳ groups exposed to 95 % O2 -5 %CO2,1.7%, 3.4% and 5.1% sevoflurane respectively. A549 cells were exposed to sevoflurane for 2, 4 and 6 h respectively and then cultured for another 48 h in Ⅱ , Ⅲ and Ⅳ groups. Proliferation of A549 cells were measured by methyl thiazolyl tetrazolium (MTT) assay, and apoptosis was detected with flow cytometer at 48 h after 2, 4 and 6 h sevoflurane exposure. The expression of Survivin in A549 cells was determined by Western blot analysis at 48h after 4 h sevoflurane exposure. Results The rate of proliferation inhibition and percentage of apoptotic cells were significantly higher while the expression of Survivin was significantly lower in a concentration-dependent manner in Ⅱ , Ⅲ and Ⅳ groups as compared with group Ⅰ . Conclusion Sevoflurane can inhibit proliferation and induce apoptosis of A549 cells by inhibition of Survivin expression.

ObjectiveTo observe the clinical effect of Jie-jing Mixture in treating spasticity of apoplectic hemiparalysis.Methods60 cases with spasticity of apoplectie hemipuralysis were divided into 2 groups.30 case for treatment group (routine treatment added by Jie-jing Mixture ) and 30 case for control (only receiving routine treatment ).ResultsThe effective rates was 86.7% (treatment group )and 33.3%(control group )with statistical significance ( P<0.01).Conclusions The Jie-jing Mixture has better effect in treating spastisticity of apoplectic hemiparalysis than that of the conventional therapy.

After 28 foreign species of AM fungi were inoculated in sterilized soil, the effects of the AM mycorrhizal colonization and the medicine quality of Paris polyphylla var. yunnanensis were observed by combination of inoculation test in pot at room temperature and instrumental analysis. The results showed that, compared with control group (CK), the inoculation of foreign AM fungi in the soil influenced the spore density, mycorrhizal infection rate, and colonization intensity of AM fungi in root system of P. polyphylla var. yunnanensis. The inoculation of foreign AM fungi enhanced the mycorrhiza viability of P. polyphylla var. yunnanensis by increasing the activity of succinic dehydrogenase (SDH) and alkaline phosphatase (ALP) in intraradical hyphae. The content of single steroid saponin in rhizome of P. polyphylla var. yunnanensis showed variation after P. polyphylla var. yunnanensis was inoculated by different foreign species of AM fungi, which was beneficial for increasing the medicine quality; however, the kinds of steroid saponin showed no difference. In a degree, there was a selectivity of symbiosis between P. polyphylla var. yunnanensis and foreign AM fungi. And we found that the Claroideoglomus claroideum and Racocetra coralloidea were best foreign AM fungi species for cultivating P. polyphylla var. yunnanensis under field condition.
