A 20-year-old male patient presented to the Department of Dermatology of Peking Union Medical College Hospital with complaints of an 8-year history of facial scarring, swelling of the lower limbs, and a 4-year history of scalp thickening. Physical examination showed thickening furrowing wrinkling of the skin on the face and behind the ears, ciliary body hirsutism, blepharoptosis, and cutis verticis gyrate. Both lower limbs were swollen, especially the knees and ankles. The skin of the palms and soles of the feet was keratinized and thickened. Laboratory examination using bone and joint X-ray showed periostosis of the proximal middle phalanges and metacarpals of both hands, distal ulna and radius, tibia and fibula, distal femurs, and metatarsals.Genetic testing revealed two variants in SLCO2A1, c.1658T > A and c.96+4A > C.Through multidisciplinary consultation, we confirmed the diagnosis of pachydermoperiostosis.

Purpose: The aim of this study was to investigate the feasibility of an intelligent handheld ultrasound (US) device for assisting non-expert general practitioners (GPs) in detecting carotid plaques (CPs) in community populations. Methods: This prospective parallel controlled trial recruited 111 consecutive community residents. All of them underwent examinations by non-expert GPs and specialist doctors using handheld US devices (setting A, setting B, and setting C). The results of setting C with specialist doctors were considered the gold standard. Carotid intima-media thickness (CIMT) and the features of CPs were measured and recorded. The diagnostic performance of GPs in distinguishing CPs was evaluated using a receiver operating characteristic curve. Inter-observer agreement was compared using the intragroup correlation coefficient (ICC). Questionnaires were completed to evaluate clinical benefits. Results: Among the 111 community residents, 80, 96, and 112 CPs were detected in settings A, B, and C, respectively. Setting B exhibited better diagnostic performance than setting A for detecting CPs (area under the curve, 0.856 vs. 0.749; P<0.01). Setting B had better consistency with setting C than setting A in CIMT measurement and the assessment of CPs (ICC, 0.731 to 0.923). Moreover, measurements in setting B required less time than the other two settings (44.59 seconds vs. 108.87 seconds vs. 126.13 seconds, both P<0.01). Conclusion Using an intelligent handheld US device, GPs can perform CP screening and achieve a diagnostic capability comparable to that of specialist doctors.

ObjectiveTo observe the effect of modified Tianwang Buxindan （MTBD） on the skin of sleep-deprived （SD） mice and investigate its mechanism. MethodSixty 2-month-old female Kunming mice were randomly divided into a blank group， a model group， a vitamin C （VC， 0.08 g·kg^-1）， and MTBD low-， medium-， and high-dose groups （6.5， 12.5， 25 g·kg^-1）. Except for the blank group， the other groups were subjected to SD mouse model induction （using multiple platform water environment method for 18 hours of sleep deprivation daily from 15：00 to next day 9：00）， continuously for 14 days， and caffeine （CAF， 7.5 mg·kg^-1） was injected intraperitoneally from the 2nd week onwards， continuously for 7 days. While modeling， the blank group and the model group were administered with normal saline （0.01 mL·g^-1）， and the other groups received corresponding drugs for treatment. On the day of the experiment， general observations were recorded （such as body weight， spirit， fur， and skin）. After sampling， skin tissue pathological changes were observed under an optical microscope using hematoxylin-eosin （HE） and Masson staining methods. Skin thickness and skin moisture content were measured. Biochemical assay kits were used to detect skin hydroxyproline （HYP） content， skin and serum superoxide dismutase （SOD） activity， and malondialdehyde （MDA） content. Enzyme-linked immunosorbent assay （ELISA） was used to detect serum interleukin （IL）-6， tumor necrosis factor （TNF）-α， and IL-1β levels in mice. Western blot was used to detect skin tissue type Ⅰ collagen （ColⅠ）， type Ⅲ collagen （ColⅢ）， phosphatidylinositol 3-kinase （PI3K）， phosphorylated （p）-PI3K， protein kinase B （Akt）， p-Akt， nuclear factor E₂-related factor 2 （Nrf2）， heme oxygenase （HO）-1， and nuclear factor （NF）-κB protein expression. ResultCompared with the blank group， the model group showed varying degrees of changes. In general， signs of aging such as reduced body weight （P<0.01）， listlessness， dull fur color， and formation of wrinkles on the skin appeared. Tissue specimen testing revealed skin thinning， flattening of the dermoepidermal junction （DEJ）， and reduced collagen fibers under the optical microscope. Skin thickness and moisture content decreased， skin tissue HYP content significantly decreased （P<0.01）， skin and serum SOD activity significantly decreased （P<0.01）， and MDA content significantly increased （P<0.01）. Serum IL-6， TNF-α， and IL-1β levels significantly increased （P<0.01）. Skin ColⅠ， ColⅢ， p-PI3K/PI3K， p-Akt/Akt， Nrf2， and HO-1 protein expression significantly decreased （P<0.05， P<0.01）， and NF-κB expression increased （P<0.01）. Compared with the model group， the VC group and the MTBD low-dose group showed increased skin moisture content， HYP content， SOD activity， and ColⅠ， ColⅢ， p-PI3K/PI3K protein expression （P<0.05， P<0.01）， and decreased serum MDA content （P<0.05）. In addition， a decrease in serum IL-6 and IL-1β levels was detected in the MTBD low-dose group （P<0.05）， while the above indicators in the MTBD medium- and high-dose groups improved （P<0.05， P<0.01）. ConclusionSleep deprivation accelerates the aging process of the skin in SD model mice. MTBD can improve this phenomenon， exerting anti-inflammatory and antioxidant effects， and its mechanism of action may be related to the activation of the PI3K/Akt/Nrf2 signaling pathway.
