Deconstruction of lignocellulosic plant cell walls to fermentable sugars by biochemical means is impeded by several poorly understood ultrastructural and chemical barriers. Pretreatment is an essential step by altering the morphological and compositional characteristics of biomass to enhance the sugar release during enzymatic hydrolysis. Therefore, getting insight into this field is necessary to improve the conversion of biomass into biofuels. In this review, we highlight our recent understanding on the impact of various promising pretreatments on biomass, with emphasis on the topochemical and ultrastructural changes of plant cell walls that are related to the reduction of recalcitrance and the consequence of saccharification. It will lend support to the scientific research and development with respect to biomass conversion.

Objective To evaluate the role of spinal Toll-like receptor 4 (TLR4) signaling pathway in the development of inflammatory pain in rats.Methods Thirty-six adult male Sprague-Dawley rats were divided into 3 groups (n=12 each) using a random number table:control group,inflammatory pain group and TLR4 signaling pathway inhibitor epigallocatechin gallate (EGCG) group (EGCG group).Inflammatory pain was induced by injecting 50 μl of complete Freund's adjuvant (CFA) into the ankle joint cavity of the left hindpaw of rats anesthetized with isoflurane.At 1-3 days after injection of CFA,EGCG 30 μg was intrathecally injected once a day in group EGCG.At 1,3 (30 min after intrathecal injection),5and 7 days after injection of CFA,the mechanical paw withdrawal threshold (MWT) and thermal paw withdrawal latency (TWL) were measured.The ipsilateral L4.5 segments of the spinal cord were removed at 3 days after CFA injcction for determination of TLR4 expression (by Western blot) and contents of tumor necrosis factor-alpha (TNF-oα),interleukin-6 (IL-6) and IL-1β in the spinal dorsal horn (by enzymelinked immunosorbent assay).Results Compared with control group,the MWT was significantly decreased and the TWL was shortened at each time point after injection of CFA,the expression of TLR4 in the spinal dorsal horn was up-regulated,and contents of TNF-α,IL-6 and IL-1β in the spinal dorsal horn were increased in inflammatory pain group (P＜ 0.05),and no significant change was found in the parameters mentioned above in EGCG group (P＞0.05).Compared with inflammatory pain group,the MWT was significantly increased and the TWL was prolonged at each time point after injection of CFA,the expression of TLR4 in the spinal dorsal horn was down-regulated,and contents of TNF-α,IL-6 and IL-1β in the spinal dorsal horn were decreased in EGCG group (P＜0.05).Conclusion Spinal TLR4 signaling pathway is involved in the development of inflammatory pain in rats.

Objective:To study the role of indocyanine green(ICG)fluorescence imaging in laparoscopic partial splenectomy (LPS).Methods:The data of 4 patients who underwent ICG fluorescence imaging technology for LPS at Beijing Luhe Hospital Affiliated to Capital Medical University from May 2017 to May 2020 were retrospectively analyzed. There were 3 females and 1 male, aged 46, 41, 27 and 12 years respectively. The extents of spleen preservation were compared between ICG fluorescence imaging with ordinary white light during operation. The residual splenic remnants were tested with fluorescence imaging after splenectomy, which showed fluorescence fading indicating good vascular perfusion.Results:ICG fluorescence imaging was performed on 4 patients. The operation time ranged from 180.0 to 250.0 min, and the intraoperative blood loss ranged from 40.0 to 200.0 ml. The postoperative hospital stay ranged from 4 to 14 days. There were no serious complications. Postoperative histopathology showed: splenic cyst ( n=1), splenic hemangioma ( n=2), and splenic laceration ( n=1). Conclusions:ICG fluorescence imaging technology had a significant role to play in partial splenectomy. This study showed this technique to improve safety of laparoscopic partial splenectomy.
