The protective effect of Astragalus saponins or Astragalus mongholicus bunge on the micro -model of cultured new born rat heart cells infected with Coxsackie B, virus was observed. After inoculation with 1000 TCID Coxsackie B, virus, the cardiac enzyme lactic acid dehydrogenase (LDH) was much lower in the Astragalus saponins or Astragalus mongholiais bunge treated groups than in those untreated groups, but the synthesis rate of DNA was higher. Virus titer in the supernatant of cultures was detected 48 h after virus challenge. The virus titer of the Astragalus saponins (Lg 3.78 TCID) or the Astragalus mongholiais bunge (Lg 4.33 TCID50) treated groups was lower than in those untreated groups (Lg 5.78 TCID50). These results show that the Astragalus saponins may be a useful drug in treatment of acute viral myocarditis.

Macrophage colony-stimulating factor receptor(c-Fms),encoded by the c-fms proto-oncogene,is a member of type III receptor tyrosine kinase family. c-Fms activation by binding with its ligand plays important roles in the survival, proliferation and differentiation of the monocyte-macrophage lineage and the development of embryo. Over expression of c-Fms and its ligand result in abnormalities of intracellular signaling pathways mediated by c-Fms, which is associated with tumorigenesis and inflammation. The inhibitors targeting c-Fms block intracellular signaling pathways by inhibiting c-Fms receptor tyrosine kinase are potential drugs for tumor and arthritis therapeutics.

Objective To investigate the effect of TanshinoneⅡA (TSN) on the cell hypertrophy induced by angiotensinⅡ(AngⅡ) in the primary culture of neonatal rat cardiomyocytes. Method The effect of TSN on cardiomyocyte was evaluated by the 3-[4, 5-dimethylthiazol-2-yl] -3, 5-diphenylformazan (MTF) assay. As the index of eardiomyocyte hypertrophy, protein synthesis rate was measured by H-Leucine incorporation and the cell size was determined by phase contrast microscope. The proto-oncogene c-los mRNA and c-jun mRNA expression was assessed using reverse transcription polymerase chain reaction (RT-PCR). Results Exposure of the myocytes to TSN (5～80 mmol/L) for 24hours produced no cytotoxicity. Protein synthesis rate and proto-oneogene c-fos and c-Jun mRNA expression of eardinmyoeytes increased significantly after AngⅡtreatment, and TSN inhibited these effect of AngⅡ.Conclusions TSN can prevent the hypertrophy of eardiomyocytes induced by AngⅡ, which be attributable relate to the decreased expression of proto-oncogene c-los and c-jun mRNA by TSN.

This system is designed to effectively grease stacin,moisture and particde in the com- pressed air through various fictering mater als.In the same machine,it can finish a series of proce- dures such as washing,drying,filling and sealing the ampoules.It not only shorten the production process,reduce contamination links,but also increase the end product rates by 10% whereas de- crease the ampoule loss rates by over 5%.Simple,safe and reliable,it saves time,labour and elec- tric energy.

The effects of antibacterials are mainly focus on inhibiting the proliferation of the bacteriums or killing them directly in various ways. Consequently, antibacterials were mainly used in the therapy of infectious diseases. However, besides the effect of anti bacterials, some antibacterials have other effects as well, such as the effects of antitumor, immunomodulation and antivirus etc. So it is very important to understand the effects and their mechanisms of antibacterials roundly so as to apply them more rationally.

Objective: To study the relationship between blood pressure (BP) rhythm and cognitive function in elder hypertension patients. Methods: Our research included in 2 groups: Hypertension group:n=74 patients≥80 years and Control group, n=36 elder subjects without hypertension. 24-hour ambulatory blood pressure monitoring (ABPM) was conducted in both groups. According to nocturnal BP reduction rate, Hypertension group was further divided into 4 subgroups as Dipper type BP subgroup, Non-dipper type BP subgroup, Anti-dipper type BP subgroup and Super-dipper type BP subgroup. Cognition function was evaluated by Mini-menta state examination (MMSE) form, MMSE score was compared among different groups and subgroups. Results: By MMSE score, the abilities of orientation, memory, attention, calculation and recall were different between Hypertension group and Control group,P<0.05. By MMSE score, the abilities of orientation and memory were different between Anti-dipper type BP subgroup and Dipper type BP subgroup,P<0.05; the abilities of orientation, memory, attention, calculation and recall were different between Non-dipper type BP subgroup and Dipper type BP subgroup,P<0.05; the memory was different between Super-dipper type BP subgroup and Dipper type BP subgroup,P<0.05. Conclusion: In elderly hypertension patients, compared to those with normal BP rhythm, the abnormal BP rhythm patients had the higher probability to suffer from cognitive dysfunction which was mainly as decreased abilities of orientation, memory, attention, calculation and recall.

This study was aimed to solve the problem of overall syndrome differentiation information collection on patient’s main complain of traditional Chinese medicine (TCM) four diagnostic methods, in order to make syndrome differentiation standard of premenstrual syndrome (PMS) with liver-qi invasion pattern. The method of cluster sampling was applied in the investigation. The appropriate structural equation modeling (SEM) was established according to multi-dimension indexes of case features and TCM theories. The results of the “information acquisition form for doctor” structural equation showed that emotion dimension, body-symptom dimension, organism condition dimension load coefficients were 0.715, 0.574 and 0.904, respectively. The results of the “information acquisition form for patient” structural equation showed that emotion dimension, body-symptom dimension, organism condition dimension load coefficients were 0.705, 0.945 and 0.848, respectively. There were strong relativities among all dimensions. Combined with TCM theories, the main symptom of identified PMS with liver-qi invasion pattern was “irritable and angry”. And the secondary symptoms contained headache, breast tenderness, distention and pain of lower abdomen and stomach. The combining symptoms were insomnia, dreaminess, swelling of extremities, fatigue, inefficiency for work and housework, hard to focus the attention. It was concluded that the combination of information acquisition method from both the doctor and patient established a relative comprehensive information acquisition system. It established the syndrome differentiation standard of PMS with liver-qi invasion pattern for the first time based on epidemiologic investigation. It provided important reference for the study of PMS subtype.

Objective To compare the efficacy and safety of robot assisted laparoscopic radical prostatectomy (RALRP) and retropubic radical prostatectomy (RRP).Methods From May 2004 to September 2013,data from 124 prostate cancer patients were collected.Of them,41 cases underwent RALRP,and 83 cases underwent RRP.The following clinical data was reviewed and analyzed,including operation time,blood loss,transfusion rate,duration of catheterization,time of postoperative hospital stay,postoperative pathology,continence and biochemical recurrence.Results All the operations were successfully performed,without RALRP converted to open surgery.The mean operation time of the RALRP group and the RRP group was 224 min and 165 min,mean blood loss was 266 ml and 659 ml,the transfusion rates were 20％ and 86％,the mean postoperative hospital stay was 16.4 d and 17.9 d,the positive margin rates were 24％ and 10％,the differences were significant (P ＜ 0.05).The mean catheterization time was 27.2 d and 23.5 d (P ＞ 0.05).The 6-month,1-year and 2-year biochemical recurrence rates were 8％,21％ and 24％ in RALRP group,and 13％,16％,31％ in RRP group.The 3-month,6-month,1-year and 2-year continence rates were 56％,70％,80％ and 94％ in RALRP group,and 55％,70％,78％ and 79％ in RRP group.For biochemical recurrence and continence rates,there was no significant difference between the 2 groups.Conclusions RALRP possesses advantages of less bleeding and faster recovery.In addition,the effect of postoperative oncology and continence is similar to open surgery.
