Objective To evaluate the roles of B-type natriuretic peptide (BNP) in predicting the severity of community-acquired pneumonia (CAP) by studying the correlation between them.Methods A total of 202 patients with CAP admitted from December 2011 to December 2012 were enrolled in this study.All these patients were checked with laboratory tests for BNP level,C-reactive protein (CRP),white blood cell count (WBC) as well as other markers needed for obtaining pneumonia severity index (PSI).The differences in BNP levels,CRP levels,and WBC were compared among different degrees of pneumonia severity,and the correlation between BNP levels and PSI was investigated by a linear correlation analysis.The patients enrolled were divided into a high-risk group (defined as Ⅳ-Ⅴ grade of PSI) and a low-risk group (defined as Ⅰ-Ⅲgrade of PSI).Meanwhile,they were also divided into a survivor group and a non-survivor group according to outcomes.BNP levels between the two groups were compared,and a receiver operating characteristic (ROC) curve analysis was performed on the BNP levels versus PSI.Results BNP levels increased with CAP severity (r =0.782,P ＜0.01).The mean level of BNP (263.2 ± 119.6) pg/mLof patients in the high-risk group was significantly higher than that of patients (71.5 ± 54.3) pg/mL in the low-risk group (P ＜ 0.01).The patients in the non-survivor group had significantly higher BNP levels compared to the survivor group [(343.86 ± 125.49) vs.(183.00 ±121.71) pg/mL,P ＜ 0.01].In addition,there were positive correlations between BNP levels and PSI (r =0.782,P＜0.001),between BNP levels and CRP levels (r =0.560,P＜0.01),and between BNP levels and WBC (r =0.513,P＜0.001).The BNP level had a high accuracy in predicting the severity of CAP (AUC =0.952).The optimal cut-off point of BNP level for distinguishing high-risk from low-risk patients was 125.0 pg/mL,with a semitivity of 0.891 and a specificity of 0.946.Moreover,BNP level had a definite accuracy in predicting mortality (AUC =0.823).Its optimal cut-off point for predicting death was 299.0 pg/mL,with a sensitivity of 0.675 and a specificity of 0.816; its negative predictive cut-off value was 0.926,and positive predictive value was 0.426.Conclusions BNP level is positively correlated with the severity of CAP.The patient with BNP level above 125.0 pg/mL should be hospitalized immediately and patients with BNP level higher than 299.0 pg/mL are at the high risk of death.Therefore,BNP is a useful biomarker for evaluating the severity of patients with CAP.

Cryptotanshinone (CPT)is a major fat-soluble ingre-dient in Salvia,which is a traditional blood-activating and stasis-dissolving drug.CPT has been gradually concerned,because it has a remarkable therapeutic effect on cardiovascular diseases, cancer and neurodegenerative diseases.A large number of exper-imental and clinical studies have shown that CPT can primarily inhibit tumor cell′s proliferation,angiogenesis,invasion and ad-hesion and induce apoptosis.Thus to some extent,it hinders in-vasion of tumor cell and prevents the distant metastasis.This pa-per focuses on the anti-tumor metastasis of CPT.

OBJECTIVE: To establish a rapid molecular identification method for Polygonatum filipe species. METHODS: Polymorphism analysis on DNA of P. filipe and P. cyrtonema was performed by using inter simple sequence repeat (ISSR) and sequence-related amplified polymorphism (SRAP) molecular markers. Differential ISSR and SRAP bands between the two species were sequenced and species-specific sequence characterized amplified region (SCAR) primers were designed for the identification of P. filipe and P. cyrtonema. RESULTS: Under respective optimal annealing temperature, three pairs of SCAR primers can specifically amplify three fragments of 150, 354 and 518 bp only from P. filipe, respectively, not from P. cyrtonema. The SCAR-PCR test was simple and convinent to operate, and reproducible. The molecular identification technology based on SCAR markers was further validated by testing 8 samples of Polygonatum tubes sold in market. CONCLUSION: SCAR molecular technology developed in this study can be used for the assistant identification of P. filipe species.

BACKGROUND: Although pneumonia severity index (PSI) is widely used to evaluate the severity of community-acquired pneumonia (CAP), the calculation of PSI is very complicated. The present study aimed to evaluate the role of B-type natriuretic peptide (BNP) in predicting the severity of CAP. METHODS: For 202 patients with CAP admitted to the emergency department, BNP levels, cardiac load indexes, inflammatory indexes including C-reactive protein (CRP), white blood cell count (WBC), and PSI were detected. The correlation between the indexes and PSI was investigated. BNP levels for survivor and non-survivor groups were compared, and a receiver operating characteristic (ROC) curve analysis was performed on the BNP levels versus PSI. RESULTS: The BNP levels increased with CAP severity (r=0.782, P<0.001). The BNP levels of the high-risk group (PSI classes Ⅳ and Ⅴ) were significantly higher than those of the low-risk group (PSI classes Ⅰ–Ⅲ) (P<0.001). The BNP levels were significantly higher in the non-survivor group than in the survivor group (P<0.001). In addition, there were positive correlations between BNP levels and PSI scores (r=0.782, P<0.001). The BNP level was highly accurate in predicting the severity of CAP (AUC=0.952). The optimal cut-off point of BNP level for distinguishing high-risk patients from low-risk ones was 125.0 pg/mL, with a sensitivity of 0.891 and a specificity of 0.946. Moreover, BNP level was accurate in predicting mortality (AUC=0.823). Its optimal cut-off point for predicting death was 299.0 pg/mL, with a sensitivity of 0.675 and a specificity of 0.816. Its negative predictive cut-off value was 0.926, and the positive predictive cut-off value was 0.426. CONCLUSION: BNP level is positively correlated with the severity of CAP, and may be used as a biomarker for evaluating the severity of CAP.
