The objective of this study is to evaluate the performance of three models for estimating daily evapotranspiration(ET) by employing flux observation data from three years(2007, 2008 and 2009) during the growing seasons of winter wheat and rice crops cultivated in a farmland ecosystem(Shouxian County) located in the Huai River Basin(HRB), China. The first model is a two-step model(PM-Kc);the other two are one-step models(e.g., Rana-Katerji(R-K) and advection-aridity(AA)). The results showed that the energy closure degrees of eddy covariance(EC) data during winter wheat and rice-growing seasons were reasonable in the HRB, with values ranging from 0.84 to 0.91 and R2 of approximately 0.80. Daily ET of winter wheat showed a slow decreasing trend followed by a rapid increase, while that of rice presented a decreasing trend after an increase. After calibrating the crop coefficient(Kc), the PM–Kc model performed better than the model using the Kc recommended by the Food and Agricultural Organization(FAO). The calibrated key parameters of the R-K model and AA model showed better universality. After calibration, the simulation performance of the PM-Kc model was satisfactory. Both the R-K model and AA model underestimated the daily ET of winter wheat and rice. Compared with that of the R-K model, the simulation result of the AA model was better, especially in the simulation of daily ET of rice. Overall, this research highlighted the consistency of the PM-Kc model to estimate the water demand for rice and wheat crops in the HRB and in similar climatic regions in the world.

慢性阻塞性肺疾病(chronic obstructive pulmonary disease,COPD)是一种因长期吸入有毒颗粒,特别是吸烟所导致的进行性肺功能障碍(疾病),持续接触这些有害物质会引发异常的炎症反应,进而造成呼吸系统永久性损伤,最终导致不可逆的病理变化。肺巨噬细胞(lung macrophages,LMs)是关键的先天免疫效应细胞,在识别、吞噬和清除病原体,以及处理吸入的有害颗粒物(如香烟烟雾和颗粒物PM)方面扮演着重要角色。LMs在炎症因子的激活下向M1或M2方向极化,分别发挥着促炎/抗炎作用,参与COPD肺实质的损伤(肺气肿)和修复(气道重塑)的全过程。它们还负责吞噬和清除凋亡或坏死的组织细胞,共同维护COPD患者肺内的微环境稳定。现代研究揭示,巨噬细胞极化在COPD的发病与发展中占据着举足轻重的地位,其具备减轻气道炎症、抑制组织重塑,以及抗氧化应激等多重功效,因此被视为COPD治疗的潜在靶点。近年来,中医药及其活性成分靶向M1/M2巨噬细胞极化平衡治疗COPD的研究成为热点领域,以巨噬细胞极化状态的调节为目标,通过中医药及其活性成分的干预平衡COPD患者肺组织中的炎症反应,并促进修复过程。该文深入探讨了近年中医药及其活性成分在这一领域的研究成果,旨在为COPD的精准诊疗策略提供新的科学依据和有力支持。

目的通过基因检测早期诊断家族性高胆固醇血症(familial hypercholesterolemia,FH)一家系,旨在提高临床医生对FH的识别及诊断能力,早期进行干预治疗。方法收集就诊于福建医科大学附属第一医院神经内科高胆固醇血症家系的临床资料,并进行基因测序分析。结果家系成员中有7例发现存在高血胆固醇、高血低密度脂蛋白胆固醇(LDL-C),患者年龄8~59岁。Ⅱ5因反复心绞痛,检查发现冠脉狭窄行冠状动脉支架置入术。基因检测发现所有患者均存在LDLR基因Exon13 c.1879 G>A(p.A627T)位点杂合突变,最终诊断为FH。结论FH起病隐匿,早期无明显临床症状,极易漏诊。基因检测技术对FH患者及其亲属进行遗传筛查,不仅有助于早期诊断,还可根据基因型进行个体化治疗,特别是对儿童患者的预防性治疗具有重要意义。

AIM To explore the effects of omeprazole on chemoradiotherapy efficacy and tumor recurrence in rectal cancer. METHODS The medical data of 125 rectal cancer patients who received the same neoadjuvant chemoradiotherapy(CRT) followed by surgery were retrospectively collected. Patients who received omeprazole(OME) orally at a dose of 20 mg at least once daily for six days and/or intravenously at 40 mg a day were recognized as eligible OME users(EOU). Otherwise, patients were regarded as non-eligible OME users(non-EOU).Moreover, a preferred OME dose cut-off of 200 mg on tumor recurrence was obtained by receiver operating characteristic(ROC) curves. Patients were divided into two groups: the effective OME group(EOG, OME ≥ 200 mg) and the non-effective OME group(non-EOG, OME < 200 mg). RESULTS The good response rate of CRT efficacy(50.8%) in EOU was significantly increased compared with nonEOU(30.6%)(P = 0.02). The recurrence rate in the EOG was 10.3%, which was significantly lower compared with 31.3% in non-EOG(P = 0.025). The good response rate of CRT efficacy in EOG was 55.2%, which was obviously higher compared with 36.5% in non-EOG, with a significant difference(P = 0.072). Multivariate Cox analysis demonstrated that OME(nonEOG and EOG) was an independent and significant impact factor for DFS(P = 0.048, HR = 0.30, 95%CI: 0.09-0.99).CONCLUSION When applied as an adjuvant drug in cancer treatment for relieving common side effects of chemotherapy, omeprazole has a synergetic effect in improving CRT efficacy and decreasing rectal cancer recurrence.
