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.

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.

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.
7. Macrophage colony-stimulating factor receptor and its inhibitors: Research advances
Journal of International Pharmaceutical Research 2010;37(5):340-345
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 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.

Objective To study the prevention and treatment of severe complications of percutaneous radiofrequency ablation(PRFA)for hepatic malignancy. Methods A series of 939 patients with primary hepatic carcinoma or hepatic metastasis confirmed by pathological examinations or clinical manifestations underwent 1098 treatments of PRFA between January 2006 and December 2009. All the patients were followed up to study the short-or long-term complications related to PRFA. Results Complications developed in 9 patients: bile duct injury (4 patients), hemothorax (2 patients), and intra-abdominal hemorrhage (3 patients). The incidence of complication was 0.82% (9/1098) and the complication-related mortality was 11.1% (1/9). Conclusions Although PRFA which is minimally invasive, is a safe and effective treatment, there were still risks for this procedure, especially when the tumor is located at the portahepatic region or the patient has coagulopathy. Some serious complications can be prevented. It is important to observe the strict indications for RFA and to carry out the procedure carefully. Early detection of complication is important.

Objective To evaluate the clinical value of SAA by detecting their expression levels in patients with lung cancer and the analysis of the relativity of SAA for early diagnosis.Methods There are 243 cases specimens obtained from lung cancer patients who were newly diagnosed and without any treatment in Zhejiang Cancer Hospital from April 2014 to June 2015.The 243 lung cancer individuals were 147 male, and 96 female, their ages ranged from 29 to 85 years, with an average age of 63 years.The distribution of pathological type was as follows:95 patients were adenocarcinoma, 102 patients were squamous carcinoma, and 46 patients were small cell carcinoma.The distribution of TNM staging systems was as follows: 59 patients in stage 1and stage 2, 54 patients in stage 3, and 130 patients in stage 4.While 179 cases physical examination as the control.There were 94 individuals male, and 85 individuals female.Their ages ranged from 26 to 86 years, with an average age of 61 years.By using latex enhanced immune turbidimetric method, serum SAA concentrations in patients with lung cancer and healthy controls were checked on the Hitachi-7600 automated chemistry analyzer ( Hitachi ).The comparisons of all analyses values between healthy controls and lung cancer were estimated by two independent samples nonparametric tests ( Mann-Whitney U).The association between SAA and lung cancer prognostic factors such as age, smoking status and metastasis, was evaluated by spearman correlation and multivariate analysis.Results The median and interquartile spacing of SAA concentration was 42.36 mg/L (9.35, 74.22) in lung cancer patients.While 24 mg/L ( 3.25, 21.45 ).The median level of SAA in lung cancer patients (42.36 mg/L) were significantly higher than in healthy controls (11.24 mg/L), and difference reached statistically significant (Z=-2.403,P=0.006).Nevertheless, there was no significant difference in SAA concentrations among the different pathological types(Z=-1.013, P=0.339), ages (Z=0.578, P=0.458) and gender(Z=0.726, P=0.246) of lung cancer patients.While the level of SAA in has smoking status (Z=-2.282, P=0.013) and distant metastasis (Z=-2.138, P=0.017) of lung cancer was higher.By drawing ROC curve, the cut off value of SAA in distinguishing lung cancer with healthy control was 14.48 mg/L.Meanwhile, the AUC was 0.811, the accuracy is 89.12% and the sensitivity was 88.73%.Serum concentration was positively related with smoking status ( r =0.331, P =0.018 ) and distant metastasis ( r =0.372, P=0.015 ) by Spearman correlation analysis .Conclusion Serum SAA concentrations may contribute to the auxiliary diagnosis of lung cancer, evaluate the clinical stage and distant metastases of lung cancer.
