目的:分析睑板腺功能障碍型干眼(MGD)和水液缺乏型干眼(ADDE)患者的像差和散射相关参数,评估两种干眼类型患者的视觉质量。方法:将2018-01/10在我院门诊就诊的MGD患者25例(MGD组),ADDE患者25例(ADDE组),同时期就诊的健康人25例(对照组)纳入此次研究。三组受试对象填写眼表疾病指数量表(OSDI),接受泪液相关检查:泪液分泌试验(SⅠt)、泪膜破裂时间(TBUT)、角膜荧光染色(FL)。使用iTrace分析仪记录三组受试对象的高阶像差(HO)、球差(SA)、彗差(CA)和三叶草差(TA)的均方根值(RMS)。利用双通道视觉分析仪(OQASⅡ)记录三组受试对象自然状态下的散射值,包括调制传递函数截止频率(MTF cutoff)、斯特列尔比(SR)、客观散射指数(OSI),以及持续睁眼状态下OSI动态变化值(OSI均值)。结果:MGD组的OSDI评分明显高于ADDE组(38.2±5.6 vs 32.2±7.2分,P0.05;CA:t=1.80,P>0.05;TA:t=1.50,P>0.05;SA:t=1.97,P>0.05)。MGD和ADDE组之间的MTF cutoff、SR、OSI无差异(MTF cutoff:33.28±8.28 vs 37.12±9.53,SR:0.19±0.06 vs 0.22±0.08,OSI:1.30±0.32 vs 1.12±0.52,MTF cutoff:t=1.52,P>0.05;SR:t=1.50,P>0.05;OSI:t=1.47,P>0.05)。持续睁眼状态下MGD组的OSI均值明显高于ADDE组(2.386±0.118 vs 1.554±0.058,P<0.001)。结论:治疗干眼的同时需要关注改善患者的视觉质量,MGD患者的视觉质量影响比ADDE患者更加严重。泪膜动态状态下的OSI均值是评估干眼患者视觉质量的敏感指标。

Circular RNAs(circRNAs) play pivotal roles in the development and progression of various diseases, including malignant tumors. However,the biological functions and the underlying mechanisms of many circRNAs remain elusive. In this study, we identified a novel circRNA,circTP63-N, generated through the splicing of exons 2–4 of the TP63 gene in nasopharyngeal carcinoma(NPC). circTP63-N was found to be downregulated in clinical samples of NPC. Both in vitro and in vivo experiments unequivocally demonstrated that circTP63-N inhibits the proliferation and metastasis of NPC cells. Further investigations revealed that circTP63-N interacted with the HSP90AB1 protein, leading to the recruitment of LATS/YAP1 proteins. This, in turn, induced phosphorylation and ubiquitination-dependent degradation of YAP1, resulting in reduced nuclear translocation of YAP1 and inhibition of the transcriptional activation of downstream oncogenic genes, including INHBA, MMP3, and CCNE2. Our findings highlight the identification of circTP63-N, a novel circRNA encoded by an important tumor-relevant gene TP63 and elucidate its molecular mechanism as a tumor suppressor in NPC. These insights offer novel potential molecular markers and therapeutic targets for the clinical diagnosis and treatment of NPC.

Because of the important role of the absorption heat pump in low-grade thermal energy utilization, this paper extends it to micro domain and performs a finite-time thermodynamic modelling for a three-heat-reservoir (THR) thermal Brownian heat pump with heat transfer effect by using an equivalent combined cycle method, which was applied for macro endoreversible THR heat pumps. The working principle and energy transformation rule are studied, and the coefficient of performance (COP) and heating load are derived. With a fixed overall thermal conductance of three heat exchangers, the maximal heating load is determined by optimizing thermal conductance distributions among three heat exchangers and barrier height, and the optimal working temperatures are also obtained. The impact of external heat transfer is elucidated to show the difference between this model and a non-equilibrium thermodynamic one. Results indicate that external heat transfer determines the energy transformation directly, and performance characteristics are closer to reality when external heat transfer is considered. The heating load has a maximal value about thermal conductance allocation ratios. About half the overall heat exchanger inventory needs to be assigned to the heat exchanger of the heating space for maximal heating load. When the cycle is with only heat transfer effect, the net particle numbers are zero, and the cycle fails to pump heat. The research results are expected to offer an idea for thermodynamic optimization and design of micro THR thermal Brownian heat pump devices.
