CEPS sludge was compared with conventional primary and secondary sludge for the VFAs yield. Fe-based CEPS sludge exhibited the highest efficiency of organic recovery. Fermented CEPS sludge liquor provided a sufficient carbon source for denitrification. 99% of nitrate removal was achieved based on the Fe-CEPS and sludge fermentation.

超滤(UF)工艺已广泛应用于饮用水处理中。然而,藻类及其分泌物会导致严重的膜污染,在实际生产过程中对超滤工艺构成巨大挑战。本文开发了一种简单实用的化学强化反冲洗(CEB)技术,考察了次氯酸钠(NaClO)、氯化钠(NaCl)、氢氧化钠(NaOH)、柠檬酸钠及其组合对藻源膜污染的控制效能。结果表明,化学清洗剂的类型是影响超滤膜水力不可逆膜污染(HIMF)的关键因素。其中,NaClO 对HIMF的控制效果最佳,其次是NaCl。此外,与单独使用NaClO相比,将NaClO与NaCl、NaOH或柠檬酸钠等组合使用对HIMF的控制效果并没有明显提升。NaClO 的最优投加量和投加方案为10 mg∙L−1,且最佳投加频次为每天两次。通过开展长周期的中试和生产实验进一步表明CEB技术可有效缓解藻源膜污染,尤其是HIMF。此外,与不添加化学药剂的常规水力反冲洗相比,CEB技术主要是通过氧化作用有效地去除包括生物聚合物、腐殖质和蛋白质类物质等在内的有机污染物,削弱有机污染物与膜表面之间的黏附力,从而显著降低HIMF。因此,CEB技术可在低药剂条件下有效地缓解藻源膜污染,是一种有效阻控超滤处理含藻地表水过程膜污染的方法。

Primary hepatic carcinoma (PHC) is a common malignant tumor in China. Cancer is comprehensively treated with various therapeutic regimes, including traditional Chinese medicine (TCM). TCM has been widely used to improve the quality of life, delay the time of cancer progression, and prolong the median survival time. This systematic review with meta-analysis aimed to assess the effect of TCM combined with Western therapy on primary hepatic carcinoma. A comprehensive literature search was conducted in six databases, including CNKI, VIP, Wan-Fang Database, CBM, PubMed, and Cochrane library. A total of 44 randomized controlled trials (RCTs) involving 3429 participants suffering from PHC were selected. Meta-analysis results indicated that the overall effect of TCM and Western integrative treatment on PHC was higher than that of Western intervention alone, which can postpone tumor recurrence and metastasis and prolong the overall survival time of patients with PHC. Although the obtained evidence remained weak because of the poor methodological quality of the included studies, this review provided relevant data supporting the efficacy and safety of TCM combined with Western therapies. In future research, individual RCT studies should incorporate accepted standards for trial design and reporting, proper outcome indicators according to international standards, blinding in allocation concealment, and valid follow-up periods.

Digital clubbing, which has been recognized as a sign of systemic disease, is one of the most ancient diseases. However, the pathogenesis of clubbing and hypertrophic osteoarthropathy has hitherto been poorly understood. The study of a clinically indistinguishable idiopathic form (primary hypertrophic osteoarthropathy, PHO) provides an opportunity to understand the pathogenesis of hypertrophic osteoarthropathy. Current advances in the study of PHO are discussed. The impaired metabolism of prostaglandin E2 (PGE2) plays a central role in its pathogenesis.
