At least 40% of these strains were resistant to imipenem ,aminoglycosides or the fourth generation cephalosporins .All the 4 were gram negative bacilli in Department of Respiratory Medicine ,mainly non‐fermentative bacteria and Enterobacteriaceae , most of which were multi‐drug resistant .MRSA is becoming an important pathogenic bacteria .The prevalence of E .coli is significantly different between the pneumonia associated with cerebral hemorrhage and that associated with cerebral infarction .

BACKGROUND:Owing to containing large amounts of growth factors, platelet-rich plasma has been widely used in bone regeneration, wound healing, and so on, while few studies have been reported on cartilage tissue engineering. OBJECTIVE:To explore the effects of platelet-rich plasma on the proliferation and differentiation of chondrocytes, and the feasibility of constructing tissue-engineered cartilage by the combination of chondrocytes and platelet-rich plasma. METHODS:We detected the concentrations of transforming growth factor-β, insulin-like growth factor-1, platelet-derived growth factor and epidermal growth factor BB in the whole blood, platelet-rich plasma, and activated platelet-rich plasma. The rabbit articular chondrocytes were cultured in 10%, 15%, 20%, 30%platelet-rich plasma for 7 days, then the cellproliferation was tested by cellcounting kit-8, and cartilage-related genes (col agen type II, Aggrecan, Sox-9) were determined using QT-PCR. The chondrocytes/platelet-rich plasma composite was implanted subcutaneously into the rabbits, and the samples were harvested after 6 weeks of transplantation for histological examination. RESULTS AND CONCLUSION:The levels of different growth factors in the platelet-rich plasma were higher than those in the whole blood (P<0.05), but lower than those in the activated platelet-rich plasma (P<0.05). Platelet-rich plasma at different concentrations promoted the proliferation of chondrocytes. When the concentration of platelet-rich plasma was no more than 20%, the proliferation of chondrocytes showed a concentration-dependent manner. The 20%platelet-rich plasma showed the best effects to promote the expression of col agen type II (P<0.05), while the 15%platelet-rich plasma could maximize the expression of Sox-9 and Aggrecan (P<0.05). After transplantation of chondrocytes/platelet-rich plasma composite, cartilage-like tissue formed with cartilage lacuna-like structures, and rich extracellular matrix was found, which indicates platelet-rich plasma can be used as an injective scaffold in cartilage tissue engineering.

Purpose:To investigate effect on bcl-2 and bax expression in apoptic PGCl_(3) cells and to study the mechanism of apoptosis of PGCl_(3) cells induced by death associated protein kinase(DAPK).Methods:Eukaryotic express vector pcDNA3.1-DAPK was tranfected into High-metastasis Non-small Lung Cancer Cell PGCl_(3).Changes of bcl2 and bax expression were detected with RT-PCR.Phospharation of Bcl-2 was examined with Westernblotting.Results:It was demonstrated that bcl-2 expression was down regulated,but bax expression did not change in apoptosis of PGCl_(3) cells induced by DAPK.Level of Phospharation of Bcl-2 increased.Conclusions:Apoptosis of PGCl_(3) cells induced by over-expression of DAPK may be associated with down regulating of bcl-2 expressio and increase of phospharation of Bcl-2.

Objective To investigate the effect of MT-1 and MT-2 in liver damage in chronic inorganic arsenate exposure mice and to explore the mechanism of arsenic-induced liver damage. Methods The male Kunming mice were randomly divided into control and exposed groups. The control group was given ordinary feed and tap water. The exposed group was given ordinary feed and 300 mg/L of sodium arsenite solution by drinking water. After 10 months of treatment, the activity of serum alanine aminotransferase (ALT), aspartate aminotransferase(AST) and globulin (Glb) content were determined. The total RNA was extracted by the TRIzol-phenol-chlorofor-method from the liver tissue. The quantity of the RNA was determined by spectrophotometry and its purity was judged at a ratio of A260/A280. Then real-time PCR(RT-PCR) was used to measure the mRNA expression of MT-1 and MT-2. Results Compared with the control group, serum ALT, AST activity and Glb content were higher and the MT-1 and MT-2 mRNA content was lower in the exposed group (P

OBJECTIVE: To standardize the management on test of hospital preparations to ensure the quality of preparations. METHODS: The Access database and Word application of in Microsoft Office automatic groupware were integrated organically using VBA programming, and the data management system suitable for hospital preparation test was designed. RESULTS: The print files of various primary records and reports related to testing work exhibited beautiful page and uniformed format. Testing data of preparations were included into data base by computer recording, which facilitated data inquiry and data processing related to quality of hospital preparations. CONCLUSION: Due to this system, both the efficiency and quality of hospital preparation test work have been enhanced, which contributes to institutionalization and standardization of hospital preparation work.

Objective To study the phenotype profiles of bone marrow micrometastatic tumor cells in patients with breast cancer. Methods Immunocytochemical staining was used to study the biologic markers of disseminated tumor cells, and U-PA activity of the plasma in the bone marrow was assayed in breast cancer patients.Results Judged by positive immunocytochemical staining of EMA and CK19, bone marrow micrometastasis was found in 30 out of 72 (41 67%) breast cancer patients. The primary tumor size (? 2=6 417, P=0 040) and p53 protein expression (? 2 =5 930, P=0 025) were significantly correlated with the incidence of micrometastasis. Disseminated tumor cells expressed low protein cyclinD1, p53,Ki-67, EGFR, and high protein p21. Tumor size and axillary lymph node status were found to be significantly correlated with the u-PA activity level. Conclusion Disseminated tumor cells in the bone marrow was in a status of low-cycling and low-proliferation.

Objective:To compare the sleep behaviors and the coping styles between chronic insomniacs and normal sleepers.Methods:The self-made questionnaire of sleep behaviors (including the irrational beliefs and attitudes toward sleep, the dysfunctional sleep behaviors and anxiety on evening),the coping styles and the internal-external locus of control(I-E) score were administered to 62 chronic insomniacs and 62 normal sleeper matched by age and sex.Results:The irrational beliefs and attitudes toward sleep, the dysfunctional sleep behaviors, the anxiety on evening, and the scores of I-E and of the self-blame in coping style were higher in the chronic insomniacs than in normal controls. The scores of problem-solving of the chronic insomniacs were lower than that of the normal controls. Regression analysis indicated the irrational beliefs about sleep and the dysfunctional sleep behaviors were associated with problem-solving and I-E scores.Conclusions:Chronic insomnia group has irrational beliefs and attitudes toward sleep, they have more dysfunctional sleep behaviors and higher anxiety on evening. Their ability of problem-solving is impaired and they incline to attribute their fate to external control.
