OBJECTIVE To study the distribution and drug resistance supervision of infection pathogens of Gram-negative bacterial pneumonia in lower respiratory tract of senile patients and draft preventive and control measures.METHODS The sputum and lower respiration secretion of 368 senile patients were cultured to detect pathogens which were confirmed by routine methods.The disk diffusion test was adopted to analyze drug resistantce.RESULTS Pseudomonas aeruginosa rated the top one,reached 25.0%;the drug resistance supervision manifested that the resistant rates of Gram negative organisms to the routine drugs were high except for Haemophilus influenzae.And extensive-spectrum beta-lactamases(ESBLs) occurred with rate of 30.2%.CONCLUSIONS It is very necessary for clinical microbiology department to detect pathogens of lower respiratory tract pneumonia among senile patients and then to give reasonable advice for medicine in time.

OBJECTIVE To investigate the spread status and drug-resistance of pathogenic bacteria causing chronic bacterial prostatitis among the senile patients,and provide the reference for clincal diagnosis and treatment.METHODS Prostatic fluid from the senile patients with chronic bacterial prostatitis was collected,and bacterial cultures and susceptibility tests were performed.The data were analyzed statistically.RESULTS Among 216 prostatic fluid specimens from the senile patients with chronic bacterial prostatitis,140 isolates of pathogenic bacteria were detected.In these strains,Gram-positive cocci accounted for 60.0% and most of them were Staphylococcus aureus.Gram-negative bacilli accounted for 40.0% and most of them were Escherichia coli.Pathogens causing prostatitis have been resistant to the common antibiotics.Among the total staphylococci,meticillin-resistant Staphylococcus(MRS) accounted for 34.8%.And among the total Enterobacteriaceae,ESBLs producing bacteria accounted for 35.6%.CONCLUSIONS Chronic bacterial prostatitis in the senile patients possesses intractability and persisting.It is important to monitor the pathogens and their drug-resistance.

AIM:To develop a method for determining cholic acid by HPLC-ELSD and GC was applied to determing muscone;in Jawei Xihuang Soft Capsule(Calculus Bovis,Moschus,Venenum Bufonis,Olibanum,Myrrha).METHODS:A C18 column(Kromasil C18,5 ?m,4.6 mm?250 mm)was used as stationary phase,the mobile phase was methanol-0.01% glacial acetic acid(73:27) at a flow rate of 1.0 mL/min.The parameters of ELSD were set as follows:evaporation temperature was 40 ℃,carrier gas(N2) pressure was 200 kPa.The GC system consisted of DB-1 capillary column(30 m?0.32 mm?0.25 ?m) and FID as the detector.The programmed temperature-GC and internal standard method were employed to determine the content of muscone.RESULTS:The linear ranges of cholic acid and muscone were in the range of 45.2 ng-904 ng and 0.05 mg/mL—0.5 mg/mL respectively.The average recoveries were 99.06% and 99.40% with RSD of 1.56% and 0.95% respectively.CONCLUSION:The method is convenient and accurate,and it can be used for the quality evaluation of Jawei Xihuang Soft Capsule.

After an analysis of the matching for library and teaching model of MOOC, MOOC-related problems were pointed out, such as insufficient supplementary resources, no soft environment for attending MOOC, limita-tions of traditional service model, and how to construct a MOOC-based service model for medical teaching in library was elaborated with suggestions proposed for changing the traditional service model in library, such as bringing into full play of the advantages of intensive information and the supplementary role of library in medical teaching , and providing new types of service.

The essay discussed on how traditional Chinese medicine (TCM) recognizes the mechanism of fatigue stage from three organs of liver, spleen and heart. TCM believes the mechanism of fatigue in sub-health lies in stagnation of liver Qi due to emotional disorder and deficiency both Qi and blood due to overexertion hurting heart and spleen. Stagnation of liver Qi plays an leading role in the occurrence and development of fatigue state, while the strain of heart and spleen is the important manifestation of this state.

Objective To investigate the changes of serum cytokines IL-2,IL-8,IL-10 and IFN-? in infants with cytomegalovirus hepatitis before and after ganciclovir treatment,and explore the underlying mechanisms of ganciclovir and the immunological changes in the development and progression of cytomegalovirus(CMV) infection.Methods CMV-IgM in the serum samples of 72 infants with identified cytomegalovirus infection were measured by enzyme-linked immunosorbent assay(ELISA).CMV DNA in blood was measured by quantitative PCR.CMV-IgM(+) and CMV DNA(+) were as observed group 1(35 cases,without hepatitis).Those with abnormality of ALT were regarded as observed group 2(37 cases,with hepatitis).Another 30 matched healthy infants were enrolled as healthy control group.Levels of serum IL-2,IL-10,IL-8 and IFN-? of each group were examined by ELISA,and CMV masculine hepatitis group were cured with ganciclovir(5mg/kg,i.v.,twice per day for 14 d,and then once per day for 14 d after a 7 days'interval),then the levels of above factors were examined again.Results The levels of IL-8 and IL-10 in observed group 1 were significantly higher than those in healthy control group(t=3.74,9.56;P0.05).After ganciclovir treatment,the level of IL-2 in observed group 2 was significantly higher than that in observed group 1(t=3.41,P0.05).The levels of IL-8,IL-10 and IFN-? were decreased significantly(t=6.52,7.24,14.23;P

Aim To explore the mechanisms of Curcumin which plays a role of protecting cells through regulating the activity of GSK-3?.Methods Plasmid APPswe and BACE1-mychis were transiently co-transfected into SHSY5Y cells.The cells were treated with Curcumin and then were collected to determine the mRNA and protein levels of GSK-3?,?-catenin and CyclinD1 by RT-PCR and Western blot. Immuno-fluoresecnt staining was used to detect the location and expression of ?-catenin and GSK-3?, and ELISA was for the generation of A?.Results RT-PCR and Western blot results showed that in the cells, Curcumin inhibited the expression of GSK-3? mRNA and protein, and promoted the expression of GSK-3?-Ser9 protein (P
