Pancreatic cystic lesions(PCLs) have been increasingly recognized in clinical practice. Although inflammatory cysts(pseudocysts) are the most common PCLs detected by cross-sectional imaging modalities in symptomatic patients in a setting of acute or chronic pancreatitis, incidental pancreatic cysts with no symptoms or history of pancreatitis are usually neoplastic cysts. For these lesions,it is imperative to identify mucinous cysts(intraductal papillary mucinous neoplasms and mucinous cystic neoplasms) due to the risk of their progression to malignancy. However, no single imaging modality alone is sufficient for a definitive diagnosis of all PCLs. The cyst fluid obtained by endoscopic ultrasound-guided fine needle aspiration provides additional information for the differential diagnosis of PCLs. Current recommendations suggest sending cyst fluid for cytology evaluation and measurement of carcinoembryonic antigen(CEA) levels. Unfortunately, the sensitivity of cytology is greatly limited, and cyst fluid CEA has demonstrated insufficient accuracy as a predictor of mucinous cysts. More recently, cyst fluid glucose has emerged as an alternative to CEA for distinguishing between mucinous and nonmucinous lesions. Herein, the clinical utility of cyst fluid glucose and CEA for the differential diagnosis of PCLs was evaluated.

Bionic surface structures, inspired by the flora, were developed for Sheet-Bulk Metal Forming （SBMF） in order to locally control the friction condition by adjusting the wetting behavior. Five bionic structures were micromilled on ASP 2023 in annealed as well as hardened and tempered conditions. Subsequently, the structured surfaces were plasma-nitrided and coated with a CrA1N thin film. The influence of the treatment method on the structural geometry was investigated with the aid of a scanning electron microscope and 3D-profilometer. The wetting behaviors of water and deep drawing oil （Berufluid ST6007） on bionic surfaces were evaluated using contact angle measurements. The resulting micro-milled structures exhibit an almost identical shape as their bionic models. However, the roughness of the structured surfaces is influenced by the microstructure. The combination of plasma-nitriding and Physical Vapor Deposition （PVD） leads to an increase in roughness. All bionic struc- tures possess higher contact angles than that of the unstructured surfaces when wetted by water. This can be explained by the fact that the structural elevations block the spreading. When the bionic surfaces are wetted by deep drawing oil, the lubricant spreads in the structural cavities, leading to smaller contact angles. Furthermore, the anisotropy of the structure has an influence on the wetting behavior.

We report the case of an 84-year-old female who had a partial gastrectomy with Billroth-Ⅱ anastomosis 24 years ago for a benign peptic ulcer who now presented an acute pancreatitis secondary to an afferent loop syndrome. The syndrome was caused by a gallstone that migrated through a cholecystoenteric fistula. This is the first description in the literature of a biliary stone causing afferent loop syndrome.

In this review, we recall how stars contribute to the search for dark matter and the specific role of the Sun. We describe a more complete picture of the solar interior that emerges from neutrino detections, gravity and acoustic mode measurements of the Solar and Heliospheric Observatory （SOHO） satellite, becoming a reference for the most common stars in the Universe. The Sun is a unique star in that we can observe directly the effect of dark matter. The absence of a signature related to Weakly Interacting Massive Particles （WIMPs） in its core disfavors a WIMP mass range below 12 GeV. We give arguments to continue this search on the Sun and other promising cases. We also examine another dark matter candidate, the sterile neutrino, and infer the limitations of the classical structural equations. Open questions on the young Sun, when planets formed, and on its present internal dynamics are finally dis- cussed. Future directions are proposed for the next decade： a better description of the solar core, a generalization to stars coming from seismic missions and a better under- standing of the dynamics of our galaxy which are all crucial keys for understanding dark matter.

We read with great interest the study by Way et al.1 published in this journal,which described and compared the acute changes in central arterial stiffness(AS),wave reflections,and central hemodynamics(CH)in response to a bout of high-intensity interval exercise(HIIE)and moderate-intensity continuous exercise(MICE)in adults with *** authors reported a significant reduction in augmentation index(AIx)corrected by a heart rate(HR)of 75 beats/min(AIx@75)and central systolic blood pressure after HIIE,without significant changes in the pulse wave velocity(PWV).In view of this important research topic and our recent contributions to it,we would like to raise some points of discussion that might help to better elucidate the findings observed in the current study,and also suggest pertinent directions to further studies.

Chinese medicine practitioners apply the differentiation reasoning for decision-making. The wide scope of Chinese medicine intervention provides coverage of methods and techniques with applications to primary, secondary and tertiary levels of prevention. The rapid evolution of mathematical and computational techniques allowed the implementation of several models for pattern differentiation that were tested for several physiologic systems. Concurrently, it is argued that pattern differentiation might improve the efficacy of either traditional or conventional medical interventions. This article reviewed the influence of pattern differentiation into clinical practice organized by medical field： general pattern differentiation; genitourinary （recurrent cystitis）; cardiovascular （coronary heart disease; arterial hypertension; angina pectoris）; neurology （stroke）; surgery; metabolic （diabetes mellitus）; hepatic （cirrhosis）; gastrointestinal （chronic superficial gastritis）; orthopedic （low back pain; rheumatoid arthritis; cervical spondylosis; elbow arthritis）; oncology （gastric mucosal dysplasia; lung cancer）; gynecologic and obstetric manifestations （nausea and vomiting）. The reviewed studies presented achievements that have contributed to the integration of Chinese medicine and evidence-based medicine in the treatment of many mild and severe diseases. Target diseases considered as major public health problems were also investigated and the results are promising regarding the possibility to treat guided by pattern differentiation.

This study investigated the effects of yerba mate consumption, a South American beverage, on cardiac remodeling in rats. For this purpose, 24 male Wistar rats were divided into Control Group (CG) which received filtered water and a standard diet, and Yerba Mate Group (YM), 6 g of Ilex paraguariensis in 100 ml water and the same diet, for 30 days. The YM group showed a reduction in final body weight and food consumption without altering weight gain. Regarding cardiac remodeling, the YM group exhibited a decrease in the right ventricle weight/final body weight ratio, suggesting cardiac atrophy, without affecting the atria and left ventricle. There was no change in cardiomyocyte area or nuclear fractal dimension in both groups. However, animals that consumed yerba mate showed increased collagen deposition and a smaller fractal dimension in the left ventricle. The consumption of yerba mate at room temperature for 30 days induced changes in cardiac remodeling, as evidenced by increased collagen deposition and alterations in fractal dimension in the left ventricle.
