为了更好地开发与利用辣木籽，以辣木籽为原料，研究了不同体积分数乙醇（20%、40%、60%、80%）分级醇沉得到的辣木籽粗多糖（P20、P40、P60、P80）的单糖组成差异以及抗氧化活性，并采用紫外可见光谱（UV-Vis）和傅里叶红外光谱（FT-IR）对纯化后的辣木籽多糖结构进行表征。结果表明：4种辣木籽粗多糖的主要成分均为鼠李糖（Rha）、半乳糖（Gal）和葡萄糖（Glc），其中粗多糖P80中单糖总含量最高（84.09 μg/mg）；在4种辣木籽粗多糖中，P20（1 mg/mL）对DPPH自由基和超氧阴离子自由基清除率均最高，分别为50.24%、34.54%，P40（1 mg/mL）对羟自由基清除率最高，为76.92%，P80的总还原力最强；通过UV-Vis和FT-IR表征可知，不同体积分数乙醇能够对辣木籽粗多糖进行分级醇沉。综上，采用不同体积分数乙醇进行醇沉的辣木籽粗多糖有不同的抗氧化活性，需要根据具体应用有针对性地提取。In order to better develop and utilise Moringa oleifera seeds, the differences in the composition of key monosaccharides as well as antioxidant activity of crude polysaccharides (P20, P40, P60, P80) from Moringa oleifera seeds obtained by graded alcohol precipitation with different volume fraction of ethanol (20%, 40%, 60%, 80%) were investigated, and the structure of purified polysaccharides of Moringa oleifera seeds was characterized using ultraviolet-visible spectroscopy (UV-Vis) and Fourier transform-infrared spectroscopy (FT-IR). The results showed that the main components of the four crude polysaccharides were rhamnose (Rha), galactose (Gal) and glucose (Glc), among which the crude polysaccharide P80 had the highest content of total monosaccharides (84.09 μg/mg); among the four crude polysaccharides of Moringa oleifera seeds, P20 (1 mg/mL) had the highest scavenging rate of DPPH radicals and superoxide anion radicals, with 50.24% and 34.54%, respectively, P40 (1 mg/mL) had the highest scavenging rate of hydroxyl radicals（76.92%）, and P80 had the strongest total reducing power; it was known that different volume fraction of ethanol were able to carry out graded alcohol precipitation of crude polysaccharides from Moringa oleifera seeds by UV-Vis and FT-IR. In summary, crude polysaccharides extracted with different volume fraction of ethanol have different antioxidant activities and need to be extracted according to specific applications.

Aiming at the flexible Job-Shop lot-streaming scheduling problem, based on the single minute exchange of die(SMED), this paper established an intermingling scheduling optimization model with objections of minimizing the makespan and the total number of sub-lots, considering the flexibility of sublots splitting and sublots intermingling, automatic changeover and material transportation. Then it proposed an improved two-archive based multi-objective evolutionary algorithm to optimize the objective function. This algorithm adopted the framework of evolutionary algorithm. Based on the framework of evolutionary algorithm, it designed a two-archive based on hypervolume indicator and improved Pareto dominance to balance the convergence and diversity of the population. And according to the characteristics of lot-streaming intermingling problems, it proposed the forward/backward decoding and sub-lot splitting left-shift strategies in the decoding stage. In the stages of neighborhood exploration and global search, it designed adaptive evolution operators for lot splitting and sub-lot intermingling schemes respectively to improve the global search and local search capabilities of the algorithm. Based on different scale examples, it tested the performance of the proposed algorithm and the classical multi-objective algorithms. The experimental results show that the algorithm has obvious advantages in convergence and diversity. [ABSTRACT FROM AUTHOR]

Objective To investigate the relationships between the levels of serum microRNA-155-5p (miR-155-5p) and suppressor of cytokine signaling1（SOCS1) and the degree of lesion and the imbalance of helper T cell 17（Th17）/reg⁃ ulatory T cell (Treg) in oral lichen planus (OLP) patients. Methods Seventy-six OLP patients (observation group) were selected, including 28 non-erosive OLP patients and 48 erosive OLP patients (29 mild to moderate erosive OLP patients, 19 severe erosive OLP patients）, and meanwhile, 50 healthy volunteers (control group) were randomly selected during the same period. Peripheral venous blood of all subjects was collected. Real-time fluorescence quantitative PCR was used to detect serum miR-155-5p and SOCS1 mRNA, and flow cytometry was used to detect the of Th17 ratio and Treg ratio, and to calculate the Th17/Treg. Pearson/Spearman correlation analysis was used to analyze the relationship between serum miR-155-5p level and SOCS1 mRNA level, and their relationships with the ratios of Th17, Treg and Th17/Treg in the peripheral blood. Results Compared with the control group, the serum miR-155-5p level, Th17 ratio and Th17/ Treg in peripheral blood increased, while the serum SOCS1 mRNA level and Treg ratio in peripheral blood decreased in the observation group (all P<0. 05）. In patients with non-erosive, mile-to-moderate erosive and severe erosive OLP, serum miR-155-5p levels, Th17 ratio and Th17/Treg in peripheral blood gradually increased, while serum SOCS1 mRNA level and Treg ratio in peripheral blood gradually decreased (all P<0. 05）. Correlation analysis showed that the serum miR155-5p level was negatively correlated with serum SOCS1 mRNA level in OLP patients (r=–0. 809, P<0. 01）. Serum miR-155-5p level was positively correlated with Th17 ratio and Th17/Treg in peripheral blood (r/rs =0. 819 and 0. 820, both P<0. 05）, and was negatively correlated with Treg ratio (r=–0. 735, P<0. 05）. Serum SOCS1 mRNA level was nega⁃ tively correlated with Th17 ratio and Th17/Treg in peripheral blood (r/rs =–0. 770 and–0. 790, respectively； both P< 0. 05）, and was positively correlated with Treg ratio (r=0. 733, P<0. 05）. Conclusion The serum miR-155-5p level increased and serum SOCS1 mRNA level decreased in OLP patients, and the changes of both levels were closely related to the severity of disease and Th17/Treg imbalance.

Objective: To investigate the efficacy and safety of domestic rituximab-based chemotherapy in patients with diffuse large B-cell lymphoma. Methods: A total of 31 patients with diffuse large B cell lymphoma diagnosed in the Department of Hematology of Anhui No2 Provincial People's Hospital from March 2020 to May 2022 were retrospectively analyzed. All patients received domestic rituximab-based chemotherapy, including 25 patients with non-germinal center diffuse large B cell lymphoma and 6 patients with germinal center diffuse large B cell lymphoma.These patients received at least 2-8 cycles of combination chemotherapy for 21-28 days as a cycle, and the efficacy was evaluated and adverse events were monitored after 2 cycles. Results: In this study, 31 patients with diffuse large B-cell lymphoma were treated with rituximab-based combined chemotherapy, and the efficacy was evaluated as complete remission (CR) in 16 cases (51.6%), partial remission (PR) in 10 cases (32.3%), stable disease (SD) in 2 cases (6.5%), progressive disease (PD) in 3 cases (9.7% ). The overall response rate was 83.9% . Among 31 patients with diffuse large B-cell lymphoma treated with domestic rituximab, the incidence of common adverse reactions was as follows: hematologic toxicity 29.0% (9/31), including neutropenia, thrombocytopenia, etc. Followed by infection 19.4% (6/31), gastrointestinal symptoms 16.1% (5/31), including abdominal pain, diarrhea, constipation and so on. All the common adverse reactions were improved after symptomatic treatment. Only 1 patient had anaphylaxis (3.2%, 1/31), and 1 patient died due to severe illness. Conclusion: Domestic rituximab has good clinical efficacy and safety in the treatment of patients with diffuse large B-cell lymphoma, with few adverse reactions, which is worthy of further exploration and application.

Sharing charging piles can alleviate the current situation of difficult charging of electric vehicles. However, the shared charging pile platforms based on the third-party platform face the problem of trust; although shared charging pile platforms based on the blockchain can provide a trust environment, these platforms lack verification of users, pile owners, charging capacity and other information. In order to solve the above problems, this paper proposed a security supervision scheme of shared charging pile based on blockchain. The scheme could securely store the key information of users, pile owners or operators through the shared charging trust model based on double chain. It designed a penetrating supervision scheme on the model to check the identity of users, pile owners or operators upward and the correctness of information such as charging capacity and charging speed downward. Experimental evaluation shows that the proposed scheme can improve the security of the platform with a small overhead. [ABSTRACT FROM AUTHOR]
