OBJECTIVE To investigate the distribution and drug resistanc of nosocomial infection pathogens from lower respiratory tract in senile patients in different season.METHODS The sputum samples from lower respiratory tract infection in senile patients in two years,were collected to identify pathogens and drug sensitivity test j udged according to NCCLS standard.RESULTS The gram-negative bacilli accounted for 85.7%.The gram- posutive bacilli accounted for 14.3%.The predominant pathogens were Pseudomonas aeruginosa(20.3%),Kleb- siella pneumoniae(14.5%),Acinetobacter lwof fi(9.8%),coagulase-negative staphylococci(9.0%).The distribution and antibiotic-resistanc of main pathogens had different characteristics in different season. CONCLUSIONS Understanding the characteristics of local pathogen spectruma and the antibiotic-resistanc of main pathogens in different season were signincant on prevention and therapy of the lower respiratory tract infection in senile patients.

OBJECTIVE To investigate the distribution and drug resistance of nosocomial infection pathogens from lower respiratory tract in senile patients. METHODS The sputum and lower respiratory tract secretion in the senile patients with lower respiratory tract infection were collected nearly five years,and identified.The drug sensitivity test,the results of examination were judged according to NCCLS standard. RESULTS The Gram-negative bacilli accounted for 79.5%.The Gram-positive bacteria accounted for 20.5%.The predominant pathogens were Pseudomonas aeruginosa(19.6%),coagulase-negative Staphylococci(CNS)(18.7%),and acinetobacter lwoffi(11.6%).The resistant bacteria were markedly increasing. CONCLUSIONS The Gram-negative bacilli are the major pathogens in the senile deceased patients.The incidence of CNS infection is markedly increasing.The isolating rate of meticillin-resistant CNS is 100.0%.

Objective To investigate the possible protective effects of hydrogen sulfide (H2S) on rats with multiple organ dysfunction syndrome (MODS). Methods NaHS was taken as a donor of H2S. Forty Sprague-Dawley rats were divided into 5 groups with 8 rats in each group:sham group,MODS 12 h model group,MODS 24 h model group,NaHS protection 12 h and 24 h groups. The content of superoxidase dismutase (SOD),malondialdehyde (MDA),glutathione peroxidase (GSH-Px),alanime transaminse (ALT),creatine kinase (CK) and creatinine (Cr) in serum were measured,respectively. The histopathological changes in the heart,liver,lung,kidney and small intestine were observed. Results The serum content of SOD and GSH-Px was significantly higher in protected H2S groups (P

Increasing cerebral blood flow in ischemic penumbra helps to promote neurological function recovery.Fibroblast growth factor is closely associated with angiogenesis after stroke;it may improve cerebral blood flow in ischemia penumbra,and thus contributes to neurological function recovery.Its application will become a novel approach in the treatment of ischemic stroke.

Background and purpose: Epithelial ovarian carcinoma is the most malignant tumor in female reproductive system because of its resistance to chemotherapy. Fructose-1, 6-bisphosphatase (FBP1) is a rate-limiting enzyme in gluconeogenesis used to catalyze the hydrolysis of fructose-1, 6-bisphosphate to fructose-6-phosphate and inorganic phosphate, thereby inhibiting the effect of glycolysis in tumor cells. This study aimed to investigate the association between the expression of FBP1 and chemosensitivity. Methods: The expression level of FBP1 in ovarian cancer patients was measured by immunohistochemistry. Results: According to the results of immunohistochemistry in 209 ovarian carcinoma specimens, the percentage of positive FBP1 expression was about 49.3% (103/209). Loss of FBP1 was a negative factor of survival (42.6 months vs 62.1 months, P=0.003). Besides, patients who were sensitive to chemotherapy displayed significantly higher scores of FBP1 expression than patients who were resistant to therapy (P=0.007). Conclusion: The rate-limiting enzyme FBP1 in gluconeogenesis can be used as a biomarker for predicting the chemoresistance and prognosis of ovarian cancer patients.

Objective To investigate the expression of human bone morphogenetic protein-7(hBMP-7)in rat bone malTOW stromal cells(BMSC)with a recombinant adenovirai vector carrying the hBMP-7 gene(Ad-hBMP-7) and study the effecta of Ad-hBMP-7 transfection on BMSC difierentiation.in order to explore the possibility for hBMP-7 gene therpy.Methods The rat BMSC cultured in vitro.They were divided into 3 groups:untreated group,Ad-hBMP-7 and Ad-GFP transduced treated group.The rat BMSC were transfected by Ad-hBMP-7 and Ad-GFP. The expression of hBMP-7 was detected by RT-PCR and Western blot analysis.and the alkaline phosphatage (ALP)activity of the BMSC was observed.ResulIs In the Ad-hBMP-7 transduced treated group.hBMP-7 mRNA expression wag manifested detected by RT-PCR(470 bp),Westem blot analysis demonstrated that these cells indeed produced the hBMP-7 protein(Mr.15×103);10 days after transduction treatment,most of the BMSC were had brown black particles stained positively by ALP activity.But in Ad-GFP transduced treated group and untreated group they did not.Conclusions Ad-hBMP-7 could efficiently transfect BMSC and promote the conversion to osteoblast.The expression of hBMP-7 in rat BMSC provides a basis for hBMP-7 gene therapv.
