Abstract To explore the effect of Multi-Disciplinary Team (MDT) mode in the diagnosis and treatment of Coronavirus Disease 2019 (COVID-19) Pneumonia. A total of 65 patients with suspected COVID-19 pneumonia were included. On February 8, 2020, our hospital officially became a designated hospital for the treatment of COVID-19, and the MDT mode was implemented throughout the diagnosis and treatment for newly admitted patients with suspected COVID-19. The patients were divided into control group and observation group according to whether received MDT mode. Our results showed that the diagnosis time in the observation group was significantly shortened than that in the control group (2.51 days vs. 3.47 days) (p < 0.05). The average daily hospitalization costs in the observation group was significantly decreased in comparison with the control group (¥766.1 vs. ¥1190.4) (p < 0.001). The average daily cost of protective materials in the observation group was significantly reduced in comparison with the control group (¥4226.90 vs. ¥5308.20) (p < 0.001). Compared with the control group, the subjective symptoms of patients in the observation group were significantly improved (p < 0.001). In conclusion, the MDT mode shortens the diagnosis time of, reduces the hospitalization costs, and improves the subjective symptoms of COVID-19.

We determined the effects of enhanced recovery after surgery (ERAS) in patients undergoing radical surgery for gastric carcinoma. Sixty patients undergoing radical gastrectomy for gastric carcinoma in Lishui Hospital between March and October 2016 were randomized to receive either ERAS (30 patients) or conventional care (30 patients, controls). Clinical, economic, and laboratory indices were analyzed. ERAS patients showed faster recovery and shorter postoperative hospital stays than the controls (P<0.05). Some clinical indices (i.e., time to first flatus and defecation, time to removal of drainage tubes, time to resumption of oral feeding, time to postoperative mobilization, and postoperative complications) were significantly better in ERAS patients than in controls. Duration of postoperative infusion was lower in ERAS patients than in controls (P<0.05). In ERAS patients, serum albumin and prealbumin were higher on postoperative day 7, C-reactive protein was lower on postoperative days 3 and 7, and neutrophil count was lower on postoperative day 3 compared to the values in controls (P<0.05 for all). IgM levels were higher in ERAS patients on postoperative days 3 and 7 (P<0.05), while IgG levels were higher on postoperative day 3 (P<0.05). Total T lymphocytes were higher in ERAS patients on postoperative day 3, while helper T cells and CD4+/CD8+ ratio were higher on postoperative days 3 and 7 (P<0.05 for all). In gastric carcinoma patients, ERAS may reduce perioperative inflammation, improve immunity and postoperative nutrition, shorten hospitalization, and enhance rehabilitation.

In this paper, two low carbon microalloyed steels, named as steel A and steel B, were fabricated by ultra fast cooling (UFC). In both steels, the microstructures containing quasi polygonal ferrite (QF), acicular ferrite (AF) and granular bainite (GB) can be obtained by UFC process. The amount of AF in steel B is more than that in steel A. The size and distribution of precipitates (Nb/Ti carbonitrides) in steel B are finer and more dispersed than those of in steel A due to relatively low finish cooling temperature. The mechanical properties of both steels are effectively enhanced by UFC process. UFC process produces low-temperature transformation microstructures containing a significant amount of AF. The mechanical properties of steel B were more satisfactory than those of steel A due to the finer average grain size, the greater amount of the volume fractions and smaller size of secondary phases.

Background and Objectives: Currently, there is a serious need to find practical biomarker(s) for Major Depressive Disorder (MDD) therapeutic target(s). This study aimed to investigate the association between microRNA (miRNA, miR) expression level in Peripheral Blood Mononuclear Cells (PBMCs) and symptomatology improvement in MDD patients before and after six-week antidepressant treatment. Methods: By using an Affymetrix array that covers 723 human miRNAs, 26 miRNAs were identified with significantly altered expression in PBMCs in MDD patients, of which 10 miRNAs were selected for quantitative real-time Reverse Transcription Polymerase Chain Reaction (RT-PCR) study. Twenty out of all the 81 MDD patients were selected for miRNA expression levels testing and symptomatology assessments before and after six-week treatment. Results: Compared with the control group, the expression levels of miR-26b, miR-4743, miR-4498, miR-4485 and miR-1972 of the MDD group were significantly higher (P < 0.05); the changes of expression levels of miR-4743, miR-4498, miR-4485 and miR-1972 were positively related to retardation improvement (P < 0.05), and the change of expression level of miR-26b negatively to the improvement of day and night change (P < 0.05); regression analysis result demonstrated that the alteration of miR-4485 expression accounted for 28.8% of retardation improvement (P < 0.05). Conclusions: These five miRNAs (miR-4743, miR-4498, miR-4485, miR-1972 and miR-26b) may serve as biomarker for MDD diagnosis and therapeutic targets for MDD treatment.

A investigação química das plantas Phyllanthus cochinchinensis (Euphorbiaceae) levou ao isolamento de três novos glicosídeos fenólicos, filantuosídeos A-C, juntamente com 12 compostos conhecidos. Suas estruturas foram determinadas com base em extensivas análises espectroscópicas e métodos químicos. Dentre eles, filantuosídeos A e B são dois glicosídeos fenólicos raros, com um esqueleto C6-C3-C6. A configuração absoluta dos filantuosídeos A e B foi estabelecida por dicroísmo circular elétrico calculado (ECD) usando teoria do funcional da densidade e a sua abordagem dependente do tempo (TDDFT). Os compostos isolados também tiveram sua citotoxicidade e atividade antimicrobial testadas.

Chemical investigation of the whole plants of Phyllanthus cochinchinensis (Euphorbiaceae) led to the isolation of three new phenolic glycosides, phyllanthuosides A-C, together with 12 known compounds. Their structures were established on the basis of extensive spectroscopic analysis and chemical methods. Among them, phyllanthuosides A and B are two of the rare phenolic glycosides, featuring with a C6-C3-C6 skeleton. The absolute configurations of phyllanthuosides A and B were established by calculated electric circular dichroism (ECD) using time dependent density functional theory (TDDFT). The isolates were also tested for their cytotoxicity and antimicrobial activity.

Background: Bacterial wilt caused by Ralstonia solanacearum is the most devastating disease in peanut. Planting resistant peanut cultivars is deemed as the sole economically viable means for effective control of the disease. To understand the molecular mechanism underlying resistance and facilitate breeding process, differences in gene expression between seeds of Rihua 1 (a Virginia type peanut variety resistant to bacterial wilt) inoculated with the bacterial pathogen suspension (10(9) cfu ml-1) and seeds of the same cultivar treated with water (control), were studied using the GenefishingTM technology. Results: A total of 25 differentially expressed genes were isolated. Expression of genes encoding cyclophilin and ADP-ribosylation factor, respectively, were further studied by real time RT-PCR, and full length cDNAs of both genes were obtained by rapid amplification of cDNA ends. Conclusions: The study provided candidate genes potentially useful for breeding peanut cultivars with both high yield and bacterial wilt resistance, although confirmation of their functions through transgenic studies is still needed.
