Objective To analyze the effect of Huashi Xingyu Qingre decoction therapy through identification of the differentially expressed saliva proteins of oral lichen planus. Method The saliva of OLP patients before and after treatment were collected. Total saliva proteins were extracted. The differentially expressed saliva proteins were screened by two-dimensional fluorescence difference gel electrophoresis and identified by liquid chromatography-mass spectrometry. The differentially expressed proteins were analyzed by Western-blot. Results Six differentially expressed proteins were identified as salivary amylase, serum albumin, IgM, carbonic anhydrase VI, zinc-α2- glycoprote and sIgA. The expression level of serum albumin, IgM, carbonic anhydrase VI and zinc-α2-glycoprotein after treatment were lower than that before. However, the expression level of sIgA was higher. The differences were statistically significant. Conclusions Some differentially expressed saliva proteins of OLP before and after Huashi Xingyu Qingre decoction therapy are characterized, and they may play a vital part in the occurrence and development of OLP.

To construct and validate a deep learning-based bone age prediction model for children living in both plain and highland regions. A model named "ethnicity vision gender-bone age net (EVG-BANet)" was trained using three datasets, including the Radiology Society of North America (RSNA) dataset [training set( EVG-BANet exhibited MAD of 0.34 and 0.52 years in RSNA and RHPE test sets, respectively. In the self-established test set, the model achieved MAD of 0.47 years (95% CI: 0.43-0.50) with accuracy within 1 year of 97.72% (95% CI: 95.56-99.01%). For the external test set, MAD was 0.53 years(95% CI: 0.48-0.58), with accuracy within 1 year of 89.45% (95% CI: 85.03-92.93). EVG-BANet demonstrated high accuracy in bone age prediction, and therefore can be applied in children living in both plain and highland.

Objective:To summarize and elucidate the impact of ambient air pollution on biological aging among middle-aged and older adults.Methods:"Air pollution""Biological age""Epigenetic age""Biological aging"and"Epigenetic aging", as well as specific names of air pollutants and biological age were used as search keywords. This study searched the databases of PubMed and Web of Science for eligible English articles and CNKI, CQVIP, Wanfang, CBM, CSTP and other Chinese databases for eligible Chinese articles from inception until June 30, 2023. The language was limited to Chinese and English.Results:Among the 14 included articles, five studies investigated the impact of air pollution on DNA methylation age using different algorithms, while six studies explored the relationship between air pollutants and telomere length. Six studies focused on frailty as an outcome, and an additional study revealed the relationship between fine particulate matter (PM 2.5) and its components with composite indicator age (KDM age). The results indicated that, although different forms of biological ages were susceptible to different ambient air pollutants at different degrees, previous studies had consistently found that the increased levels of PM 2.5 and one of its major components, black carbon (BC), could significantly accelerate the biological aging of middle-aged and older adults. Similar trends were observed with nitrogen oxides (NO x) and ozone (O 3) but with relatively limited evidence. Conclusion:Major air pollutants could accelerate the biological aging of middle-aged and older adults.

The development of medical technology has prolonged the life of patients, but in the face of incurable but imminent death, hospice care is needed to help patients die comfortably, peacefully and with dignity. As important recipients of hospice care, minors need special attention because of their particularity in physiology, psychology and social roles. Suggestions on the Standard of Hospice Care Procedure for Minors makes up for the deficiency that the existing standards do not target minors as a special group, standardizes the process of hospice care, and plays a role in protecting the rights and interests of minors.

Tinea of vellus hair is caused by dermatophyte infection of vellus hairs, and commonly affects children. It usually occurs on the face, and clinically manifests as annular or semi-annular erythema gradually spreading to the surrounding area, with central clearing and a slightly elevating border covered with papules and papulovesicles. Intense inflammation, which may manifest as pustules, erosions, exudation, scales and crusts, can be observed in patients with severe tinea of vellus hair. Direct microscopy of fungi showed abundant hyphae and/or spores on vellus hairs. Topical antifungal therapy is usually ineffective, and systemic antifungal therapy should be considered. In order to reduce the high rate of missed diagnosis and misdiagnosis, and to improve clinicians′ understanding of this disease, this review summarizes the incidence, clinical manifestations, diagnosis and treatment of tinea of vellus hair.

Triptolide (TP), a major active component of Tripterygium wilfordii Hook.F. (TWHF), is used to treat rheumatoid arthritis (RA). However, it has a narrow therapeutic window due to its serious toxicities. To increase the therapeutic index, a new triptolide-loaded transdermal delivery system, named triptolide-loaded liposome hydrogel patch (TP-LHP), has been developed. In this paper, we used a micro-needle array to deliver TP-LHP to promote transdermal absorption and evaluated this treatment on the pharmacokinetics and pharmacodynamics of TP-LHP in a rat model of collagen-induced arthritis (CIA). The pharmacokinetic results showed that transdermal delivery of microneedle TP-LHP yielded plasma drug levels which fit a one-compartment open model. The relationship equation between plasma concentration and time was C=303.59×(e(-0.064t) -e(-0.287t) ). The results of pharmacodynamic study demonstrated that TP-LHP treatment mitigated the degree of joint swelling and suppressed the expressions of fetal liver kinase-1, fetal liver tyrosine kinase-4 and hypoxia-inducible factor-1α in synovium. Other indicators were also reduced by TP-LHP, including hyperfunction of immune, interleukin-1β and interleukin-6 levels in serum. The therapeutic mechanism of TP-LHP might be regulation of the balance between Th1 and Th2, as well as inhibition of the expression and biological effects of vascular endothelial growth factor.
