To investigate plasma N-terminal pro-brain natriuretic peptide (NT-BNP) levels and to assess their clinical significance in elderly patients with isolated diastolic dysfunction. Methods Plasma NT-BNP level were measured by electrochemiluminescence immunoassay in 34 symptomatic patients (Group 1), 34 asymptomatic patients (Group 2) with isolated diastolic dysfunction, and in 16elderly healthy subjects (control group, Group 3), serving controls. Colored Doppler echocardiography was performed to evaluate the patients' cardiac structures and functions. Results The plasma NT-BNP level in Group 1 was significantly higher than those in Group 2 and Group 3 and increased with the severity of heart failure. There was no significant difference of plasma NT-BNP levels between Group 2 and Group 3 (p＞0.05). A NT-BNP value of 102.75 pg/mL showed a sensitivity of 88.2%, a specificity of 87.5%, and an accuracy of 88.1% for diagnosing diastolic dysfunction. Patients with restrictive filling pattern on echocardiography had higher NTBNP levels than those of impaired relaxation pattern (1961.2±304.9 versus 460. 1±92.7pg/mL, p＜0.001). Conclusion The elevation of plasma NT-BNP level in elderly patients with isolated diastolic dysfunction correlates with the severity of their diastolic abnormalities.The level of plasma NT-BNP has an important clinical value in the diagnosis of elderly patients with isolated diastolic dysfunction.

Objective To observe the influencing factors of recurrence and metastasis for postoperative breast cancer high-risk population, and TCM regimen of syndrome differentiation and treatment was used to validate its significance for the prevention of recurrence and metastasis. Methods The influencing factors of recurrence and metastasis of 178 postoperative breast cancer high-risk cases with positive hormone receptor were studied. The recurrence and metastasis, disease-free survival and accumulative points of TCM symptoms of integrated group (with TCM syndrome differentiation and endocrine therapy) and western medicine group (with endocrine therapy) were compared. Results Lymph node metastasis, cancer staging and TCM therapy had influence on the disease-free survival rate of postoperative breast cancer high-risk patients. TCM therapy was the independent prognostic factor for disease-free survival. 3-year recurrence and metastasis rate was lower in integrated group than that in western medicine group, with statistical difference (P=0.03). The total accumulative points of TCM symptoms in both two groups decreased after treated for 3 and 6 months, integrated group showed greater significance. TCM therapy was better for the treatment of irritability, hot flash and perspiration, good for spontaneous perspiration and insomnia, but poor in dry mouth, bitter taste in mouth and fatigue. Conclusion Lymph node metastasis, cancer staging and TCM therapy are main influencing factors for recurrence and metastasis. TCM therapy with regimen of syndrome differentiation and treatment can reduce 3-year recurrence and metastasis rate, improve TCM symptoms, especially is significant for the improvement of irritability, hot flash and perspiration.

To study the effect of sodium aescinate in inducing human breast cancer MCF-7 cells apoptosis and its possible mechanism. MTT assay was used to detect the inhibitory effect of sodium aescinate on the proliferation of MCF-7 cells. The morphological changes were observed under inverted microscope. DAPI nuclear staining was used to detect the changes in cell nucleus. Annexin V-FITC/PI flow cytometry was adopted to test the apoptosis rate. Changes in apoptosis-related proteins (PARP, cleaved caspase-8 and pro-caspase-3), cell survival-associated signal molecules (AKT and ERK) and their common upstream kinase SRC was detected by Western blotting. The result showed that after different concentrations of sodium aescinate were used to treat breast cancer MCF-7 cells, they inhibited the proliferation of MCF-7 cells in a dose-dependent manner, induced cell apoptosis (typical morphological changes in nucleus, significant increase in cell apoptosis rate). The expressions of cleaved PARP and caspase-8 increased, while the expression of pro-caspase-3 decreased, which further verified sodium aescinate's effect in inducing cell apoptosis. Sodium aescinate significantly inhibited the phosphorylation of cell survival-related signal molecules (AKT, ERK) and down-regulate the activation of their common up-stream kinase SRC. The findings indicated that sodium aescinate can block signals transiting to downstream molecules AKT, ERK, inhibit the proliferation of breast cancer cell MCF-7 cell apoptosis and induced cell apoptosis by suppressing the activation of SRC.

OBJECTIVE:To provide theoretical foundation for individualized treatment of aspirin in patients with cardiovascu-lar disease. METHODS:Domestic and foreign literatures in recent years were collected and summarized. RESULTS & CONCLU-SIONS:The gene polymorphism can significantly affect the platelet activity. GPIII a PLA2,PEAR1 and PTGS1 alleles are associat-ed with aspirin resistance,and cardiovascular events have significant difference in different genotype patients. Adjusting reasonably dosage regimen and conducting individualized treatment according to the genetic testing result and other factors can reduce aspirin resistance and the incidence of cardiovascular adverse events in the patients.

This article investigated the applicability of the near infrared spectroscopy (NIR) technology, combined with the least squares support vector machines (LS SVM) used for the quality monitoring of medicated leaven fermentation. First, near infrared spectra of 67 medicated leaven samples were obtained by near infrared spectroscopy system in the wavelength range of 400 2 500 nm, and then the protease and amylase activity were measured by Folin phenol method and DNS method. Thereafter, the LS SVM was employed to calibrate models. The Rc and Rp of protease in near infrared model were 0.975 and 0.938, respectively; The RMSEC and RMSEP were 5.297 and 9.795, respectively. The Rc and Rp of amylase in near infrared model were 0.987 and 0.973, respectively; The RMSEC and RMSEP were 7.215 and 6.864, respectively. This model has good prediction ability and is suitable for quality monitoring in medicated leaven fermentation process. The research achievement could lay a certain foundation for the near infrared spectral analysis technology applied in the field of traditional fermentation processing.

OBJECTIVETo investigate diagnosis and therapeutic effects of knee joint synovial chondromatosis with arthroscopic.

METHODSFrom March 1995 to July 2011, 28 patients with knee joint synovial chondromatosis were treated. Among them, 18 males and 10 females ranging age from 25 to 81 (mean 55.2) years,the course of disease ranged from 0.5 to 15 (mean 5.6) years. Clinical manifestation mainly included pain, swell and functional limitation of knee joint. Knee open surgery (17 cases) and laparoscopic surgery (10 cases) were respectively used. Clinical symptom,image data,pathological manifestation and effects under arthroscopy were observed, Lysholm scoring was used to evaluate effects.

RESULTSAll patients were followed up except one lost, the duration ranging from 6 to 24 months. Lysholm score in knee open surgery was increased from (41.89 +/- 6.81) preoperatively to (67.73 +/- 7.62) postoperatively;while in laparoscopic surgery it was increased from (40.78 +/- 7.54) preoperatively to (77.46 +/- 8.43) postoperatively.

CONCLUSIONArthroscopic surgery, which has no risk of rupture of incision, nonunion, earlier to exercise, is a good method to diagnosis and treat knee joint synovial chondromatosis.
