ABSTRACT
Objective To investigate the clinical effect of amiodarone combined with psychological intervention in the treatment of senile rapid arrhythmia.Methods 120 cases of elderly patients with rapid arrhythmia diagnosed and treated in our hospital from January 2015 to January 2017 were divided into two groups: the control group was treated with the system, the observation group was treated with the system combined with amiodarone+The clinical data of amiodarone combined with psychological intervention in the treatment of senile rapid arrhythmia were discussed and compared with the data obtained from the two groups.Results The clinical effect of the observation group (system synthesis+amiodarone+psychological intervention) in the treatment of elderly patients with tachyarrhythmia was better than that of the control group (systematic synthesis).The clinical symptoms improved significantly and the adverse reactions were few Statistically significant (P<0.05).Conclusion The clinical effect of prescription system combined with amiodarone+psychological intervention in patients with rapid arrhythmia is significant, which can effectively improve the clinical symptoms and less adverse reactions.It is widely used in the treatment of elderly patients with rapid arrhythmia.
ABSTRACT
Objective To extract the Ginseng polysaccharide (GPS), polysaccharides of Tricholoma matsutake (PTM)and polysaccharide of Lentinus edodes (PLE)from gingeng, tricholoma matsutake and lentinus edodes respectively,and to analyze and identify their structures,and to prepare their complex,and to study the indirect antitumor activity invitro of polysaccharide complex.Methods The polysaccharides were extracted with hot water and precipitated by ethanol.The carbohydrate levels were determined by the method of phenol-sulfuric acid.The m-hydroxyphenyl method was used to determine the levels of uronic acid, and the national standard method was used to determine the levels of starch.Infrared spectroscope and chemical methods were performed to analyze their structures. Orthogonal experiment was used to study mixing methods. Cytotoxic T lymphocyte experiment and LDH release assay were performed to detect the influence of polysaccharide complex of GPS,PTM,and PLE in the CTL killing activity,and its indirect killing effect on the P815 cells.Results The extraction rates of GPS,PTM, and PLE were 8.85%,9.40%,and 10.50%;the levels of total polysaccharides were 62.96%,59.13%,and 33.86%;the levels of uronic acid were 16.44%,9.37%,and 16.44%;the starch levels were 7.26%,2.80%,and 3.77%,respectively.The identification results showed that the polysaccharides were obstrained.When the quality ratio of the three kinds of polysaccharides was 1∶1∶1 and the concentration was 600 mg·L-1 ,the CTL cytotoxicity was the highest.Conclusion The polysaccharide complex is obtained,identified and characterized. Polysaccharide complex can enhance the cytotoxicity of CTL and has the indirectly inhibitory effect on the proliferation of P815 cells.
ABSTRACT
Objective To extract,isolate and identify the polysaccharide from ginseng,and to investigate its anti-tumor activity in vitro. Methods The ginseng polysaccharide was obtained through water extraction and ethyl alcohol deposition method. Use the Sevage method to remove the protein in the crude polysaccharide. The structural characteristics of the polysaccharide were determined by FT-IR spectra.The RM-1 and HeLa cells were divided into control group and different concentrations (0,50,100,200,300,400 and 500 mg·L-1 )of ginseng polysaccharide groups. The survival rates of the cells in various groups were detected by MTT method. The indirect killing effects of ginseng polysaccharide with different concentrations (0,50,100,200,300,400 and 500 mg·L-1 )on the cancer cells were determined by CTL test. Results The extraction rate of ginseng polysaccharide was 8.7 6% and the structural characteristics demonstrated that the main component of the extract was polysaccharide.The result of MTT showed that there were no significant differences of the survival rates of RM-1 and HeLa cells between different concentrations of ginseng polysaccharide groups after treated for 24 h compared with control group (P>0.05).The result of CTL test showed that the cytototic LHD release rates in different concentrations of ginseng polysaccharide groups were increased significantly (P<0.05)compared with control group;with the increase of ginseng polysaccharide concentration, the cytotoxic LDH release rates were increased firstly and then were decreased.When the concentration of ginseng polysaccharide was 100 mg·L-1 ,the cytotoxic LDH release rate was the biggest.Conclusion Ginseng polysaccharide can indirectly inhibit the growth of the tumor cells by activating T cells and play an anti-tumor effect.
