Research progress on magnetic resonance imaging-guided proton therapy for tumors

With the application of magnetic resonance imaging (MRI)-guided photon therapy, the concept of combining real-time MRI guidance with proton therapy, namely, MRI-guided proton therapy (MRPT), has attracted widespread attention. It is expected that MRPT canmitigate the uncertaintiesduring the treatment of proton therapy to make full use of the physical advantages of protons. However, multiple electromagnetic interactions between proton therapy and MRI-guided systems may lead to mutual interference between the two systems. This article review the research progress on the MRPT system, aiming to provide certain reference for the design of MRPT system.     

Chemical constituents from the whole herb of Hemiphragma heterophyllum

Phytochemical investigation on Hemiphragma heterophyllum led to the isolation of two new compounds, heterophyllumin A (1) and heterophylliol (3), along with nine known compounds, (?)-sibiricumin A (2), iridolactone (4), jatamanin A (5), dihydrocatalpolgenin (6), 25-hydroperoxycycloart-23-en-3β-ol (7), 24-methylenecycloartanol (8), (+)-pinoresinol (9), hexadec-(4Z)-enoic acid (10), and 9,12, 15-octadecatrienoic acid (11). Their structures were elucidated on the basis of detailed spectroscopic analyses and by comparison with literature data. Further, the structure of compound 3 was unambiguously confirmed by single-crystal X-ray analysis. Some of those compounds showed moderate activity in the α-glucosidase inhibition assay.

     

Melatonin differentially regulates pathological and physiological cardiac hypertrophy: Crucial role of circadian nuclear receptor RORα signaling

Exercise‐induced physiological hypertrophy provides protection against cardiovascular disease, whereas disease‐induced pathological hypertrophy leads to heart failure. Emerging evidence suggests pleiotropic roles of melatonin in cardiac disease; however, the effects of melatonin on physiological vs pathological cardiac hypertrophy remain unknown. Using swimming‐induced physiological hypertrophy and pressure overload‐induced pathological hypertrophy models, we found that melatonin treatment significantly improved pathological hypertrophic responses accompanied by alleviated oxidative stress in myocardium but did not affect physiological cardiac hypertrophy and oxidative stress levels. As an important mediator of melatonin, the retinoid‐related orphan nuclear receptor‐α (RORα) was significantly decreased in human and murine pathological hypertrophic cardiomyocytes, but not in swimming‐induced physiological hypertrophic murine hearts. In vivo and in vitro loss‐of‐function experiments indicated that RORα deficiency significantly aggravated pathological cardiac hypertrophy, and notably weakened the anti‐hypertrophic effects of melatonin. Mechanistically, RORα mediated the cardioprotection of melatonin in pathological hypertrophy mainly by transactivation of manganese‐dependent superoxide dismutase (MnSOD) via binding to the RORα response element located in the promoter region of the MnSOD gene. Furthermore, MnSOD overexpression reversed the pro‐hypertrophic effects of RORα deficiency, while MnSOD silencing abolished the anti‐hypertrophic effects of RORα overexpression in pathological cardiac hypertrophy. Collectively, our findings provide the first evidence that melatonin exerts an anti‐hypertrophic effect on pathological but not physiological cardiac hypertrophy via alleviating oxidative stress through transactivation of the antioxidant enzyme MnSOD in a RORα‐dependent manner.     

腹腔镜解剖性肝切除术与非解剖性肝切除术的前瞻性对比研究

目的探讨腹腔镜下解剖性肝切除术和非解剖性肝切除术治疗肝癌的临床疗效。 方法按照前瞻性随机对照试验选取本院2015年1月至2018年2月期间收治的106例肝癌患者进行，按照随机数字表法分为解剖组(行腹腔镜解剖性肝切除术)和非解剖组(行腹腔镜非解剖性肝切除术)各53例。采用SPSS20.0统计软件对数据进行分析，围术期指标、肝功能指标用( ±s)表示，采用独立t检验；术后并发症发生率、术后1年复发转移率和生存率组间比较用χ²检验；P<0.05为差异有统计学意义。 结果解剖组的手术时间明显长于非解剖组，但术中出血量、输血量明显减少，住院时间显著短于非解剖组(P<0.05)。非解剖组术后第1、3、7天血清ALT、TBIL值明显高于解剖组(P<0.05)；术后1、3天血清AST值解剖组低于非解剖组(P<0.05)。解剖组术后并发症发生率为7.5%低于非解剖组22.6%(P<0.05)。解剖组与非解剖组1年总体生存率分别为94.3%和88.6%，两组差异无统计学意义(P>0.05)；1年无瘤生存率分别为90.6%和75.5%(P＝0.038)，两组差异有统计学意义(P<0.05)。 结论相对于腹腔镜非解剖性肝切除术，腹腔镜解剖性肝切除术临床疗效更好，并有效提高1年无瘤生存率，值得在临床上进一步推广应用。     

The Influence of the Common Cold on Self-Rated Health: A Population-Based Study

ObjectiveStudies on the association between self-rated health and acute conditions are sparse. The aim of this study was to examine whether individuals respond to acute conditions (such as the common cold) in health ratings as well as the effect of chronic conditions (using the Charlson comorbidity score) on self-rated health.MethodsThe national representative survey data was linked with the claims data from the Taiwan National Health Insurance for 13,723 adults ≥ 18 years. Ordered logistic regressions with fractional polynomials were estimated to determine the relationship between the frequency of common cold episodes and the Charlson comorbidity score on self-rated health. The interactions between these two variables and the baseline age were tested.ResultsSelf-rated health worsens with the increased frequency of both common cold episodes and the Charlson comorbidity score. Both variables have a non-linear relationship with self-rated health. Younger individuals put heavier weight on acute health conditions than their older counterparts.ConclusionIndividuals respond to questions regarding their self-rated health based on their acute health condition along with chronic condition. Thus the information on self-rated health depends on the timing the information is collected, and whether at that time the individual experienced acute health conditions or not.
