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.

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.

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.

Objective: To investigate the effect and mechanism of liraglutide on vasodilatation of thoracic aortic ring in experimental rats.
Methods: The thoracic aortic rings were isolated from 32 male SD rats and divided into 2 groups: Without endothelium group and With intact endothelium group, n=16 in each group. The contractile force of vascular ring was detected and the effect of liraglutide (1×10-5 mol/L) on vasodilatation of norepinephrine (NE, 1×10-6 mol/L) pre-contracted ring was observed. The aortic ring in With intact endothelium group was further divided into 2 sub-groups:①the aortic ring was pre-treated by the inhibitor of nitric oxide synthase (NOS) (L-NAME at 10-4 mol/L),② the aortic ring was pre-treated by non-specific ATP-sensitive-potassium (KATP) channel (Glibenclamide at 10-5 mol/L), n=8 in each group. The impacts of liraglutide on those 2 sub-groups were studied.
Results: Liraglutide had no effect on isolated aortic ring at basic condition. Liraglutide at (10-5 mol/L) had vasodilatation effect in both Without endothelium and With intact endothelium groups, the effect was stronger in With intact endothelium group and the maximum vasodilatation reached 17%, P<0.05. In both pre-treated sub-groups, the effect of liraglutide on vasodilatation in sub-group①reached 4%, P<0.05, and the effect in sub-group②
reached 14%, P>0.05.
Conclusion: Liraglutide had obvious effect of vasodilatation on NE pre-contracted thoracic aortic ring in experimental rats, the mechanism might be related to NOS, while KATP channel could not block the vasodilatation effect of liraglutide.

Objective:To establish a method for the determination of nimesulide granules by HPLC. Methods:An Inertsil ODS-SP C18 column(250 mm × 4. 6 mm,5 μm) was used, and the mobile phase was 0. 01 mol·L-1 potassium hydrogen phosphate anhy-drous-acetonitrile(55∶45)[adjusting pH to (7. 2 ± 0. 05) with phosphoric acid]. The detection wavelength was set at 399nm and the flow rate was 1.0 ml·min-1. The injection volume was 20 μl. Results: The linear range of nimesulide was 0.044-0.222 μg(r=0. 999 9), the average recovery was 99. 22% and RSD was 0. 46%(n=6). Conclusion:The method is simple, accurate with promis-ing sensitivity and reproducibility, and can be used in the determination of nimesulide granules .

The prognosis of advanced gastric cancer and gastroesophageal junction (GEJ) adenocarcinoma is poor. Although che-motherapy prolongs patient survival and improves quality of life to a greater extent best supportive care compared to, the median over-survival of patients with advanced gastric cancer is limited to approximately 7-10 months. With remarkable progress in the understand-ing of molecular mechanisms, molecular-targeted agents have been developed and evaluated in international randomized phaseⅢclini-cal trials. These agents may change the treatment mode of this disease. A ToGA study initially demonstrated that the trastuzumab, the monoclonal antibody of HER-2, as a molecular-targeted agent, in combination with chemotherapy, can prolong the overall survival of patients to 13.8 months. Several agents targeting angiogenesis, c-Met, PARP, and immunotherapy are currently subjected to clinical tri-als. This review summarizes the current status of molecular-targeted therapies for gastric cancer and GEJ adenocarcinoma.

Objective To study metabolism of glucose and lipidin patients with hyperandrogenism and analyze the risk of their cardiovascular disease.Methods Object of study:firstly,choosed 118 cases of women of reproductive age from April 2013 to July 2014.Then detected their serum Testosterone (T),Estradiol (E2),fasting plasma Glucose (FPG),fasting plasma insu-lin (FINS),triglycerides (TG),total cholesterol (TC),high-density lipoprotein cholesterol (HDL-C),low-density lipopro-tein cholesterol (LDL-C),lipoprotein (a),body mass index (BMI).Finally,divided them into different groups and analyzed the results using SOSS19.0 software and two independent samples t-test statistical method.Results BMI,T,FPG,HOMA-IR and TG were significantly more higher (P <0.05)in the group of hyperandr-ogenism than in the group of normal con-trol.However,E2,TC,HDL-C,LDL-C and LP(a)had no significant difference (P >0.05)in statistics between the group of hyperandrogenism and the group of normal control.Hyperandr-ogenism group was divided into PCOS group and non-PCOS group according to etiology.In those two groups,BMI,T,E2,FPG,HOMA-IR,TG,TC,HDL-C,LDL-C and LP(a)had no significant difference in statistics (P >0.05).According to the definition of obesity adults in china,78 patients with hyperan-drogenism were divided into 2 group,one with BMI normal (BMI<24 kg/m2 )and the other group with overweight and obe-sity (BMI≥24 kg/m2 ).In group with overweight and obesity,BMI,T,FPG,HOMA-IR,TG,TC,LDL-C and LP (a)were significantly higher than the group with BMI normal (P <0.05),moreover,HDL-C was significantly lower than the group normal (P <0.05).E2 had no significant difference in statistics between the two groups (P >0.05).Conclusion Investiga-tion of the relation between hyp-erandrogenism and metabolism of glucose and lipid,can not only practically guide life style and drug therapy,but also prevent cardio-vascular disease.

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.
