大戟科植物学名订正

大戟科(Euphorbiaceae)是被子植物中的大科,是热带植物区系中的重要成分,还有橡胶[Hevea brasiliensis (Willd. ex A. Juss.) Muell. Arg.]、木薯(Manihot esculenta Crantz.)、油桐[Vernicia fordii (Hemsl.) Airy Shaw]等重要的粮食、经济植物和巴豆(Croton tiglium L.)、大戟(Euphorbia pekinensis Rupr.)、余甘子(Phyllanthus emblica L.)等常用药用植物,是一个具有重要经济价值的植物类群.     

科布尔黄耆（豆科）新异名及其在中国分布的新资料

通过野外标本采集、鉴定和对国内标本馆大量标本的观察研究,在国内文献中首次报道了科布尔黄耆(As-tragalus koburensis Bunge);纠正了之前国内几个标本馆将科布尔黄耆鉴定为乳白花黄耆(A.galactites Pall.)的错误;同时将宁夏黄耆(A.ningxiaensis Podlech et L.R.Xu)处理为科布尔黄耆的一个异名;并对科布尔黄耆在中国的分布范围和生态地理特征进行了讨论。     

A comparative analysis of kinetic models of erythrocyte glycolysis

Since the 1970s, with Heinrich as a pioneer in the field, numerous kinetic models of erythrocyte glycolysis have been constructed. A functional comparison of eight of these models indicates that the production of ATP and GSH in the red blood cell is largely controlled by the demand reactions. The rate characteristics for the supply and demand blocks indicate a good homeostatic control of ATP and GSH concentrations at different work loads for the pathway, while the production rates of ATP and GSH can be adjusted as needed by the demand reactions.     

云南节肢蕨属(水龙骨科)一新种——贯众叶节肢蕨

报道了产于中国云南高黎贡山的水龙骨科Polypodiaceae节肢蕨属Arthromeris一新种——贯众叶节肢蕨A.cyrtomioides S.G Lu＆C.D.Xu。该新种的植标大小与节肢蕨A .lehmanni（Mett.）Ching相似。但叶片的背面密被绒毛,表面被短柔毛,侧生羽片9-16对。该新种在毛被方面与厚毛羽毛节肢蕨A.tomentosa W.M.Chu相似,但羽片边缘无软骨质的膜质边,侧生羽片多达9-16对。

Serum MicroRNAs Related with Chemoradiotherapy Resistance in Advanced-Stage Cervical Squamous Cell Carcinoma

OBJECTIVE: To investigate the serum microRNAs as biomarkers in predicting chemoradiotherapy resistance in advanced-stage cervical squamous cell carcinoma (ACSCC) patients. METHODS: Serum samples were collected from International Federation of Gynecology and Obstetrics (FIGO) stage IIB to IIIB cervical squamous cell carcinoma patients treated with platinum based Concomitant Chemoradiotherapy (CCRT) in our hospital during September 2013 to November 2015. Twenty well-matched samples (10 resistant and 10 sensitive) were chosen to screen the miRNA expression profile using serum samples pooled with microarrays. miRNAs expressed significantly different between two groups were further verified in 131 patients (29 resistant and 102 sensitive) serum samples with TaqMan Real-time PCR. The AUC was used to evaluate the accuracy of the biomarkers for prediction. RESULTS: MiR-136-5, miR-152-3p and miR-206 were expressed significantly different between sensitive and resistant groups. Results of 131 patients verification showed that the levels of miR-206 in sensitive samples and resistant samples were 2.715 ± 0.2115 and 14.64 ± 1.184, respectively, which was significantly different (P < .0001), while miR-136-5p and miR-152-3p could not be tested without pre-amplification reactions. Univariate analysis revealed that miR-206 expression was significantly associated with patients' DFS. Multivariate analysis demonstrated that miR-206 expression, tumor differentiation and pelvic lymph nodes metastasis were the independent prognostic factors associated with DFS in this cohort (P = .008, 0.000, 0.000, respectively). The probability of the prognostic accuracy of miR-206 expression in predicting chemoradiotherapy sensitivity of ACSCC patients was 91.3% (79.3% sensitivity and 92.2% specificity). CONCLUSION: Serum miR-206 is a powerful tool in predicting chemoradiotherapy sensitivity in ACSCC patients.
