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.

Objective To study the clinical features ,the high risk features ,the treatments and the outcomes of chronic obstruc-tive pulmonary disease(COPD) patients combined with invasive pulmonary aspergillosis(IPA) .Methods The clinical dates of 48 COPD patients combined with IPA were retrospectively analyzed .Results The clinical manifestations of 48 COPD patients com-bined with IPA were dyspnea ,lung rales ,chest pain ,cough ,cough phlegm ,fever .Radiological findings were presented as pulmonary inflammatory exudation ,consolidation ,cavity of lungs .The treatments were effective in 16 cases ,ineffective in 32 cases .Conclusion Early diagnosis and treatment is important in COPD patients combined with IPA .

Gap junction is one kind of synapse coexisting with chemical synapse in the nervous system. Nowadays with the development of electrophysiological technique,more research began to focus on the role of gap junction in the neural network,especially in the cognitive function. Gap junction collaborates with chemical synapses to induce the neural network activities related to memory and perception,such as gamma and ripple oscillation,which is regarded as the mechanism of the role of gap junction in cognitive function. This review introduces the structure of gap junction,distribution and expression of different kinds of connexins in central nervous system,which are the basic element of gap junction. Furthermore,this review discusses the role of gap junction in cognition related network oscillations and activity-dependent plasticity of gap junction.

AIM: To explore the clinical therapeutic effect of compound Xueshuantong combined with laser treatment in central serous chorioretinopathy ( CSCR) patients.
METHODS: A total of 181 cases of central serous chorioretinopathy patients treated in our hospital were randomly divided into treatment group ( 91 cases ) and control group ( 90 cases ) . The patients in control group underwent laser treatment, those in treatment group received oral compound Xueshuantong after laser treatment. Clinical curative effect, the average light sensitivity and serum testosterone, estrogen levels of two group were compared.
RESULTS: After 3wk of treatment, the total effective rate of the treatment group was 90. 1%, 72. 2% in the control group, the treatment group was significantly higher (χ2 = 10. 473, P= 0. 001 ); After 6wk of treatment group, the total effective rate was also significantly higher than that in the control group (χ2 = 4. 499, P= 0. 034). Healing time, visual recovery time in treatment group was significantly less than those in the control group, the mean sensitivity was significantly higher, the difference between the two groups was statistical significance ( P<0.05). After the treatment the hormone of patients in the two groups were significantly decreased, the treatment to reduce the level of serum hormone level was significantly better than those in the control group, the difference between the two groups was statistical significance ( P<0.05).
CONCLUSION: Compound Xueshuantong combined with laser in the treatment of central serous chorioretinopathy, can significantly improve the efficacy, shorten the course of disease, is conducive to the recovery of visual function, and worth the clinical promotion.

Clinical trials have demonstrated that arsenic trioxide was effective in the treatment of acute promyelocytic leukemia. Based on this fact, more and more studies have been carried out to study its role in the treatment of human hepatocarcinoma cell. This article reviews arsenic trioxide in trial studies and clinical use of hepatoma carcinoma cell.

Yi Guan Jian decoction is a traditional Chinese medicine formula noted in Wei Yu-huang's Xu Ming Yi Lei An (Supplement to the Classified Medical Records of Famous Physicians). Acne vulgaris and chronic pelvic inflammation could be successfully treated by the decoction following the principle of formula corresponding to syndromes. The identical characteristics of constitution are found among the patients treated by the decoction, known as the "Yi Guan Jian constitution". It indicates that patients can be treated according to the constitutional characteristics.
