为探讨长吻海蛇（Hydrophis platurus）的宏观及微观形态特征，运用经典分类及扫描电镜观察方法，对相关标本的形态特征及鳞片微皮纹结构进行观察，结果表明：标本深色的背面与浅色的腹面具有清晰的分界，吻部明显突出，背、腹部鳞片的形状和大小无明显分别；背部鳞片显微皮纹结构表现为多个耳状结构沿身体纵轴方向交错排列，整个视野呈现为波纹状，耳状结构之间为较深的沟槽，耳状结构侧面布满小孔。标本形态结构符合长吻海蛇形态特征，其鳞片显微皮纹结构与同属眼镜蛇科（Elapidae）的陆上种类，如舟山眼镜蛇（Naja atra）、广西华珊瑚蛇（Sinomicrurus peinani）明显属于不同模式。长吻海蛇鳞片显微皮纹结构表现出显著的水生生活适应特征，此结构特征有利于长吻海蛇在游泳时减少阻力，其沟槽和小孔有利于对海水截留。研究结果认为，蛇类鳞片显微皮纹结构具有明确的分类学意义，但鳞片超微结构差异可能不适合用于推断蛇类系统进化关系。

青头潜鸭(Aythya baeri),东亚鸟种,曾广泛分布于从东北亚到东南亚并印度次大陆的广大地区[1],因其数量明显下降于20世纪90年代中期被视为易危物种(VU)[2],2008年被提升为濒危物种(EN)、2012年再升至极危物种(CR),“因其数量骤降”[3]。

Objective: To investigate the difference of the attention bias of the resilience level of professional technicians in hospital to negative information. Methods: A total of 383 professional technicians of logistics administrative posts in a third-level military hospital were selected and divided into high and low groups according to their scores on the resilience scale (the top 27% of the participants were in the high resilience group, and the bottom 27% were in the low resilience group). There were 22 participants in each of the high and low resilience groups that met the requirements. The attention bias test was conducted on the professional technicians in the high and low resilience groups using the Dot-probe Paradigm. A mixed experimental design of 2 (group: low resilience group, high resilience group) x2 (stimulus clues: negative stimulus, neutral stimulus) was adopted. The dependent variables were correct rate and reaction time. Results: The interaction between the response group and the stimulus cue was statistically significant (P<0.05), the response time of negative stimulus in low resilience group was lower than that of neutral stimulus. The main effect of the cue condition was statistically significant in both groups (P<0.05), the correct rate of negative stimulus was lower than that of neutral stimulus. Conclusion: This study shows that the professional technicians in the high resilience group do not have obvious attention bias to negative information, while the professional technicians in the low resilience group have obvious attention bias to negative emotional information.

The spleen is the largest lymphoid organ of the body, which participates in the regulation of metabolic balance. High altitude hypoxia environment can affect lipid metabolism in spleen tissue, but the key mechanism of lipid metabolism is still unclear. We aimed to use lipidomic analysis to study the effect of high altitude hypoxia on lipid metabolism in mouse spleen tissue. C57BL/6 mice were placed at an altitude of 4 200 m and 400 m, respectively, and after 30 days the spleen tissues were harvested and lipidomic analysis was performed using an ultra-high performance liquid chromatography-Orbitrap mass spectrometry system. Under the high altitude hypoxia environment, the spleen index of mice and the white pulp decreased, and the germinal center expanded with other pathological changes. The results of lipidomic analysis showed that a total of 41 lipid subclasses and 2 473 lipid molecules were identified, and triacylglycerides (TGs) and phosphatidylcholines (PCs) were the two most identified lipid molecules. Using univariate and multivariate analysis, 44 differentially expressed lipid molecules were identified, which were mainly concentrated in phospholipid metabolism. Subsequently, RT-qPCR was performed on the key enzymes hes in the phospholipid metabolic pathway, and it was found that the mRNA expression levels were different (P<0.05). It suggested that high altitude hypoxia environment mainly affects the phospholipid metabolism of mouse spleen tissue via reducing the contents of PC and phosphatidic acid (PA), promoting their conversion to phosphatidylethanolamine (PE) and cardiolipin (CL) and facilitating the PE production via the CDP-Etn pathway. This study provides a new experimental basis for the abnormal metabolism of phospholipids in spleen tissue under high altitude hypoxia environment. [ABSTRACT FROM AUTHOR]

Objective: To explore the therapeutic effect of combination of Gusegzumab and Xiaobi Tang on psoriasis vulgaris and its impact on blood cell derived inflammatory markers. Methods: 86 patients with psoriasis vulgaris admitted to our hospital from October 2020 to October 2023 were selected. They were divided into an observation group and a matched group, with 43 patients in each group. The matched group received treatment with Gusegzumab, while the observation group received treatment with Gusegzumab combined with Xiaobi Tang. Compare the clinical efficacy of two groups of patients, including changes in blood cell derived inflammation indicators, changes in Th17/Treg cell levels, and changes in liver and kidney function before and Post-treatment. Results: The total effective rate of the observation group was higher than that of the matched group(P<0.05); Pretherapy, there was no difference in the levels of NLPR, dNLR, AISI, SII, SIRI, MLR, PLR, and NLR between the two groups of patients(P>0.05). Post-treatment, the levels in both groups of patients decreased. The observation group was lower than the matched group(P<0.05); Pretherapy, there was no difference in Treg, Th17, and Th17/Treg between the two groups of patients(P>0.05). Post-treatment, there were differences between the two groups, and between the observation group and the matched group(P<0.05); There was no difference in the expression levels of liver function related indicators such as alkaline phosphatase(ALP), glutamic pyruvic transaminase(ALT), glutamic oxaloacetic transaminase (AST), blood creatinine (Scr), urea nitrogen (BUN), and cystatin C (CysC), as well as renal function related indicators between the two groups of patients Pretherapy(P>0.05), Post-treatment, there was no change in liver function related indicators such as ALP, ALT, and AST in the two groups of patients. The observation group showed a decrease in renal function related indicators such as SCr, BUN, and CysC, and the observation group was lower than the matched group (P<0.05). Conclusion: The combination of Gusegzumab and Xiaobi Tang has a significant therapeutic effect on psoriasis vulgaris, and can reduce the level of blood cell derived inflammatory indicators in the body. The anti-inflammatory response may be related to the combination therapy further regulating the Th17/Treg balance, and increasing Xiaobi Tang treatment does not cause significant damage to the patient's liver function, which can improve the level of renal function.

OBJECTIVE: To systematically review the efficacy and safety of silver sulfadiazine ointment in local treatment of burn. METHODS: PubMed, Embase, the Cochrane Library and other databases were retrieved to collect the randomized controlled study with silver sulfadiazine ointment in local treatment of burn ( intervention with silver sulfadiazine and control with other materials). The retrieval time was from Jan. 1st, 2010 to Jun. 1st, 2022. For the included randomized controlled studies, Cochrane bias risk assessment tool was used to evaluate study quality, and RevMan 5. 3 software was used for Meta-analysis to compare the wound healing time and infection rate of burn treated by silver sulfadiazine and other materials. RESULTS: Totally 11 studies were included. Meta-analysis results showed that compared with other materials, silver sulfadiazine could not shorten the wound healing time of burn, and the difference was not statistically significant (MD= -0. 31,95%CI = -2. 89-2. 26,P = 0. 81). Meanwhile, there was no significant difference in the infection rate between silver sulfadiazine group and other materials group (18. 09% vs. 14. 81%, P>0. 05). CONCLUSIONS: Based on current clinical studies, silver sulfadiazine has shown worse effect on wound healing in burn than other materials. No differences are observed between silver sulfadiazine and other materials in the prevention of infection. [ABSTRACT FROM AUTHOR]
