OBJECTIVE:To establish a method for simultaneous determination of 4 effective components in the couple of Coptidis Rhizoma and Evodiae Fmctus,and to investigate rational proportion of the couple.METHODS:HPLC method was adopted.The determination was performed on Welch XB C18 column with mobile phase consisted of acetonitrile-1.5 mmol/L sodium dodecyl sulfate solution (pH adjusted to 5.0 with phosphoric acid) (gradient elution) at the flow rate of 1.0 mL/min.The detection wavelength was set at 265 nm,and the column temperature was 30 ℃.The sample size was 10 μL.RESULTS:The linear ranges of berberine hydrochloride,martin hydrochloride,evodiamine and rutacarpine were 2.24-44.80 μg/mL(r=0.999 9),1.26-31.50 μg/mL(r=0.999 8),2.70-81.00 μg/mL(r=0.999 8),1.65-49.50 μg mL(r=0.999 9),respectively.RSDs of precision,stability and reproducibility tests were all lower than 3.0%.The recoveries were 98.11%-100.73% (RSD=1.04%,n=6),96.54%-103.47%(RSD=1.86%,n=6),95.49%-102.36% (RSD=2.05%,n=6),97.19%-103.24% (RSD=2.19%,n=6),respectively.When the proportion of Coptidis Rhizoma-Evodiae Fructus(m/m) was 2∶ 1,the comprehensive content of each component was the highest.CONCLUSIONS:The method is simple,accurate,stable and reproducible,and can be used for simultaneous determination of 4 effective components in different compatibility proportions of the couple of Coptidis Rhizoma and Evodiae Fructus.The rational proportion of the couple of Coptidis Rhizoma and Evodiae Fructus is 2 ∶ 1.
3.Neuroremodeling and depression
Chinese Journal of Behavioral Medicine and Brain Science 2016;25(12):1142-1146
Depression is a common mental and psychiatry disorder. Depression is easy to recur and hard to cure.These urgent problems origin from the limited understanding of this disease and the big heteroge-neity in its genology. Generalized from recent relative papers we discovered that the important onset and sus-taining basis of depression is neuroremodeling,which includes the persistent changes of histocytology,ultra-structure of synapse and abnormal expressions of gene and protein of neurons in key brain regions,and so on. These changes affect the correct dealing on the neural message which lead to depression and become the sus-taining biological basis. Therefore the key strategies to prevent and cure depression lie on preventing,individ-ual therapy and reversing neuroremodeling.

Objective To study the pathological and ultramicrostructural characteristics of organ tissues in relation to the clinical course of severe acute respiratory syndrome (SARS). Methods Post-mortem tissue samples of organs (lungs, heart, liver, spleen, kidneys, pancreas, stomach ) were obtained by needle biopsy from four SARS patients who died in middle and late stages 3-5 weeks after the onset of the disease. The pathological samples were studied by light and electron microscope, immunohistochemistry, histochemistry and indirect immuno-fluorescent antibody test. Results The main pathological features were early interstitial pulmonary fibrosis or organizing pneumonia. Fibroblasts were increased in the interalveoli septa and young connective tissue was found to fill the alveoli. Diffuse alveolar damage (DAD) with alveolar pneumocytes proliferation and an increase in macrophages were found. Desquamative alveolitis also existed at the same time. Squamous metaplasia and syncytial giant cells with multinuclei could be seen. CD3 + and CD20 + lymphocytes were markedly decreased and CD68 + macrophages and S-100 + dendritic cells increased in spleen. Proliferation of bone marrow cells became restrained . Hepatocytes were vacuolated with fatty degeneration. Electron microscopy showed the presence of coronavirus-like particles 80-60nm in diameter enveloped in the cytoplasm of the type Ⅱ pneumocytes, endothelial cells and lymphocytes. Conclusions A novel coronavirus is the cause of the newly recognized severe acute respiratory syndrom (SARS). The main target organs are lung and immune system. Different pulmonary pathological features were found in patients dying from the disease in different stages. All of specimens showed positive reaction of SARS-fluorescence antibody.

Objective To examine current use, associated complications, and short-term outcomes in patients with acute myocardial infarction (AMI) requiring intra-aortic balloon pump (IABP) counterpulsation. Methods A single-centre registry was conducted between October 2004 and July 2008. Data were collected from 121 consecutive AMI patients treated with IABP counterpulsation at the 28th Division of Beijing Anzhen Hospital. Results Among 806 patients with AMI, IABP counterpulsation was employed in 121 patients. Placement of an IABP was indicated for hemodynamic support during high-risk catheterization and/or angioplasty (66.9%) and cardiogenic shock (27.3%). Balloon insertions were successful in 98.3% of patients and duration of mean use was 34.2?16.2 hours. No major IABP complications occurred in all the patients. Diagnostic catheterization was performed in all the patients inserted with IABP, and 93.4% underwent coronary revascularization before hospital discharge. The total in-hospital mortality was 13.2% (34.4% in patients with cardiogenic shock) and varied markedly by indication and use of revascularization procedures. Conclusion IABP counterpulsation may be successfully employed for a wide variety of conditions in the AMI setting, providing significant hemodynamic support with rare major complications in a high-risk patient population. IABP counterpulsation may reduce mortality in patients with AMI undergoing reperfusion therapy.
