OBJECTIVE: To assess the safety and topical efficacy of prim-O-glucosylcimifugin (POG) and investigate the molecular mechanisms of its therapeutic effects in atopic dermatitis (AD). METHODS: The effects of POG on human keratinocyte cell viability and its anti-inflammatory properties were evaluated using cell counting kit-8 assay and reverse transcription-quantitative polymerase chain reaction (RT-qPCR). Subsequently, the impact of POG on the differentiation of cluster of differentiation (CD) 4⁺ T cell subsets, including T-helper type (Th) 1, Th2, Th17, and regulatory T (Treg), was examined through in vitro experiments. Network pharmacology analysis was used to elucidate POG's therapeutic mechanisms. Furthermore, the therapeutic potential of topically applied POG was further evaluated in a calcipotriol-induced mouse model of AD. The protein and transcript levels of inflammatory markers, including cytokines, lymphocyte-specific protein tyrosine kinase (Lck) mRNA, and LCK phosphorylation (p-LCK), were quantified using immunohistochemistry, RT-qPCR, and Western blot analysis. RESULTS: POG was able to suppress cell proliferation and downregulate the transcription of interleukin 4 (Il4) and Il13 mRNA. In vitro experiments indicated that POG significantly inhibited the differentiation of Th2 cells, whereas it exerted negligible influence on the differentiation of Th1, Th17 and Treg cells. Network pharmacology identified LCK as a key therapeutic target of POG. Moreover, the topical application of POG effectively alleviated skin lesions in the calcipotriol-induced AD mouse models without causing pathological changes in the liver, kidney or spleen tissues. POG significantly reduced the levels of Il4, Il5, Il13, and thymic stromal lymphopoietin (Tslp) mRNA in the AD mice. Concurrently, POG enhanced the expression of p-LCK protein and Lck mRNA. CONCLUSION Our research revealed that POG inhibits Th2 cell differentiation by promoting p-LCK protein expression and hence effectively alleviates AD-related skin inflammation.

OBJECTIVE: To assess the outcomes after acupoint application in patients with pharyngeal pain in a real-world settings, and analyze the characteristics of effective population and prescription characteristics of acupoint application. METHODS: Based on CHUNBO platform, patients with pharyngeal pain who were candidates for acupoint application on the basis of physician-evaluation, were enrolled in a nationwide, prospective, 69-week multicenter observational study from August 2020 to February 2022. Propensity score matching (PSM) was used to match the confounding factors and the association rules were used to analyze the characteristics of effective population and prescription characteristics of acupoint application. Outcome assessments included the disappearance rate of pharyngeal pain (within 3, 7, and 14 days), disappearance time of pharyngeal pain, as well as adverse events. RESULTS: Of 7,699 enrolled participants, 6,693 (86.9%) received acupoint application and 1,450 (21.7%) with non-acupoint application. After PSM, there were 1,004 patients each in the application group (AG) and non-application group (NAG). The disappearance rate of pharyngeal pain in the AG at 3, 7, and 14 days were all higher than those in the NAG (P<0.05). The disappearance time of pharyngeal pain in the AG were shorter than that in the NAG (logrank P<0.001, hazard ratio=1.51, 95% confidence interval: 1.41-1.63). The median age of effective cases was 4 years, mainly 3-6 years old (40.21%). The disappearance rate of pharyngeal pain in the application group with tonsil diseases was 2.19 times higher than that in the NAG (P<0.05). The commonly used acupoints for the effective cases were Tiantu (RN 22), Shenque (RN 8) and Dazhui (DU 14). The commonly used herbs for the effective cases were Natrii sulfas, Radix et Rhizoma Rhei, and Herba Ephedrae. Among them, Natrii sulfas was applied to RN 8 most frequently (support 84.39%). A total of 1,324 (17.2%) patients experienced AEs, and mainly occurred in the AG, with significant difference in the incidence of AEs between goups (P<0.05). All AEs reported were the first grade, and the average regression days of AEs was 2.8 days. CONCLUSIONS Acupoint application in patients with pharyngeal pain resulted in improved effective rate and shortened duration, especially children aged 3-6 years old, and those with tonsil diseases. Acupoint of RN 22, RN 8 and DU 14, Natrii sulfas, Radix et Rhizoma Rhei, and Herba Ephedrae were the most commonly used herbs in the treatment of pharyngeal pain.

Diabetic retinopathy (DR), one of the chronic complications of diabetes, is a serious and irreversible blinding disease. It is difficult to detect in the early stage, to control in the progressive stage, to operate in the advanced stage of DR. Recently, the "14th Five-year plan" for National Eye Health proposed to "improve the management mode of chronic eye disease, and build a chronic disease management system". The project team used artificial intelligence technology based on cloud platform, joint outpatient service, virtual ward to explore the comprehensive management of DR from the aspects of early screening, multidisciplinary collaborative diagnosis and treatment, and refined blood glucose management during perioperative period. In the future, it is urgent to integrate DR chronic disease management with other systemic chronic diseases to reduce the blindness caused by DR.

OBJECTIVETo evaluate the effificacy of oral Chinese medicine (CM) in comparison with donepezil, a cholinesterase inhibitor (ChEI), for the treatment of Alzheimer's disease (AD).

METHODSRandomized controlled trials (RCTs) have been searched, and the effect of CM compared with donepezil in AD has been investigated. An electronic search of MEDLINE, Excerpta Medica Database (EMBASE), Cochrane Library, Chinese Biological Medicine Database (CBMdisc), and China National Knowledge Infrastructure (CNKI) to identify articles in English and Chinese from the inception of the database until October 18, 2015. A modifified Jadad score (7-points) to judge the methodological quality of studies, comprehensive meta-analysis was performed with Cochrane Collaboration Revman 5.3. Dichotomous data were analyzed by relative risk (RR) with a 95% confifidence interval (CI), while continuous variables were analyzed by using mean differences (MD) with 95% CI for effect size.

RESULTSSix studies involving 596 AD patients through Jadad assessment with low bias were included in the meta-analysis. No signifificant difference was observed in cognitive improvement and daily abilities of patients using the Mini Mental State Examination (MMSE) (MD: 0.69, 95% CI:-0.17 to 1.56) and Activities of Daily Living (ADL) scale (MD: 0.94, 95% CI:-1.54 to 3.43). There were no signifificant differences in status of illness or MD for mild-moderate AD patients at 24 weeks (MD: 0.62, 95% CI:-2.99 to 4.23) and 48 weeks (MD:-0.73, 95% CI:-5.02 to 3.56). Severe AD patients were also assessed at 24 weeks (MD: 3.13, 95% CI:-6.92 to 13.18) and 48 weeks (MD: 4.23, 95% CI:-6.38 to 14.84). Furthermore, compared with donepezil, Xin (Heart)-regulating CM and Shen (Kidney)-tonifying groups were observed (MD:-1.50, 95% CI:-3.08 to 0.08; MD:-1.92, 95% CI:-3.50 to-0.33; respectively). CM had fewer side effects in AD patients.

CONCLUSIONCompared with donepezil, oral CM showed no signifificant difference in effectiveness in AD patients, and more evidence is needed to verify the fifindings.

The study is aimed to test the effect of Huangqin Tang (HQT) on serum metabolic profile in rats with ulcerative colitis, and explore its possible action mechanism for ulcerative colitis (UC) rats. The model of UC rats with cell immunoreactivity was made using a compound method (trinitrobenzene sulfonic acid plus ethanol). Rats were randomly divided into the control group, the model group, and HQT group. Ultra performance liquid chromatography tandem mass spectrometry (UHPLC-MS), principal component analysis (PCA) and partial least squares-discriminant analysis (PLS-DA) were employed to analyze the metabolic profile among normal group, the model group, HQT group. Potential biomarkers were screened in the serum based on the variable importance projection (VIP) value > 1, P< 0.05. As compared with the normal group, 16 potential biomarkers such as valine, tryptophan, lactic acid and urea were found and identified in the serum of model group rats. As compared with the model group, a part of the biomarkers were restored nearly to a normal state after HQT administration for 10 days. Metabolomic analysis revealed that the HQT has a certain therapeutic effect in UC rats, and the mechanism may be related to regulation of lipid metabolism, amino acid metabolism and energy metabolism.
