ObjectiveTo analyze the distribution characteristics of traditional Chinese medicine （TCM） constitution and factors associated with hyperuricemia （HUA） in the HUA population， providing a reference for persona-lized prevention and management of HUA. MethodsA cross-sectional study was conducted among individuals who had completed both serum uric acid （SUA） testing and TCM constitution identification during health examinations. According to SUA levels， participants were divided into a hyperuricemia group and a normal SUA group； according to the constitution identification results， participants were classified into balanced constitution， single biased constitution， and mixed constitution. The distribution characteristics of TCM constitution were compared between the two groups； participants in the hyperuricemia group were stratified by sex and age （≥18 years and ＜40 years， ≥40 years）， and the distribution characteristics of TCM constitution were compared across different sex and age groups. Logistic regression was used to analyze factors associated with HUA， with further stratified analyses by sex and age. ResultsA total of 10 920 participants were included， comprising 4170 cases （38.19%） in the hyperuricemia group and 6750 cases （61.81%） in the normal serum uric acid group. According to TCM constitution， there were 420 cases （3.85%） with balanced constitution， 6108 cases （55.93%） with single biased constitution， and 4392 cases （40.22%） with mixed constitution. In the hyperuricemia group， there were 80 cases （19.05%） with balanced constitution； 2275 cases （37.25%） with single biased constitution， among which damp-heat constitution （1205 cases， 52.97%）， phlegm-dampness constitution （500 cases， 21.98%）， and qi-stagnation constitution （181 cases， 7.96%） accounted for relatively high proportions； and 1815 cases （41.33%） with mixed constitution， among which mixed constitution involving phlegm-dampness （51.35%， 932 cases）， mixed constitution involving blood stasis （47.00%， 853 cases）， and mixed constitution involving damp-heat （41.21%， 748 cases） accounted for relatively high proportions. Logistic regression showed that qi-stagnation constitution （OR=1.68）， mixed constitution involving qi-stagnation （OR=1.53）， mixed constitution involving phlegm-dampness （OR=1.55）， and mixed constitution involving blood stasis （OR=1.50） were independently associated with HUA （P＜0.05）. Sex-stratified analysis showed that mixed constitution involving phlegm-dampness was positively associated with HUA risk in females； age-stratified analysis showed that， among individuals aged ≥18 and ＜40 years， qi-stagnation constitution， mixed constitution involving qi stagnation， and mixed constitution involving phlegm-dampness were positively associated with HUA risk （all P＜0.05）. ConclusionThe prevalence of HUA differs markedly by sex and age. Mixed constitution accounts for a higher proportion of HUA patients. Qi-stagnation constitution， mixed constitution involving qi stagnation， mixed constitution involving phlegm-dampness， and mixed constitution involving blood stasis are associated with HUA. Notably， the specific association of mixed constitution involving phlegm-dampness in females and qi-stagnation constitution in young adults is particularly prominent.

Objective:To analyze factors influencing the melasma severity, and to evaluate the efficacy of different treatment modalities.Methods:A retrospective analysis was conducted on clinical data from patients diagnosed with melasma at the Pigmentary Disorders Specialty Clinic in the Department of Dermatology, Huashan Hospital, Fudan University from July 2018 to December 2023. Patients' Fitzpatrick skin types, lesion color, locations and subtypes were evaluated by dermatologists, the melasma area and severity index (MASI) scores were calculated, and ΔMASI scores (baseline MASI scores - post-treatment MASI scores) were used for efficacy evaluation. The t test and one-way analysis of variance were used to analyze factors influencing the severity of melasma, the paired t test was used to analyze the differences in MASI scores before and after treatment, and a multivariate linear regression model was established to analyze factors influencing the efficacy in the treatment of melasma. Results:A total of 254 patients (including 249 females, 98.0%) with melasma were included, with ages of 40.8 ± 6.1 years. The Fitzpatrick skin type was Ⅲ in 213 (83.9%) patients, and Ⅳ in 41 (16.1%) patients; 180 (70.9%) patients lacked the habit of using sunscreens regularly. According to the location of pigment deposition, 166 cases (65.4%) were classified as epidermal type, and 88 (34.6%) as mixed type. Pigmented lesions were located on the cheek (174 cases, 68.5%), midface (26 cases, 10.2%), or lower jaw (54 cases, 21.3%), with periorbital involvement observed in 127 cases (50.0%). Before treatment, baseline MASI scores were significantly higher in the skin type Ⅳ group (19.75 ± 5.08) than in the skin type Ⅲ group (14.47 ± 4.18, P < 0.001), in the non-sunscreen users (16.45 ± 4.61) than in the sunscreen users (12.59 ± 3.91, P < 0.001), in the epidermal type group (15.99 ± 4.82) than in the mixed type group (14.07 ± 4.35, P < 0.001), in the mandibular type group (18.37 ± 5.14) than in the midfacial type group (14.23 ± 3.46, P < 0.001) and malar type group (14.54 ± 4.40, P < 0.001), as well as in the patients with periorbital involvement (16.54 ± 4.90) than in those without (14.10 ± 4.26, P < 0.001). According to the main treatment regimens, the patients were divided into the topical 2% hydroquinone group (109 cases, topically treated with 2% hydroquinone cream nightly), topical non-hydroquinone skin-lightening agents group (36 cases, topically treated with non-hydroquinone skin-lightening or exfoliating agents), oral tranexamic acid group (50 cases, treated with oral tranexamic acid 250 mg twice daily), and alpha hydroxy acid (AHA) chemical peeling group (30 cases, receiving AHA chemical peeling treatment monthly with the AHA concentration escalating from 20% to 50%). After treatment, MASI scores were significantly reduced from baseline in all the 4 groups (all P < 0.001), and the ΔMASI values significantly differed among the topical 2% hydroquinone group, topical non-hydroquinone skin-lightening agents group, oral tranexamic acid group, and AHA chemical peeling group (1.65 ± 2.19, 1.40 ± 2.16, 4.58 ± 3.09, 3.39 ± 3.61, respectively, F = 17.40, P < 0.001). The oral tranexamic acid group and AHA chemical peeling group showed significantly superior efficacy compared to the topical 2% hydroquinone group and topical non-hydroquinone skin-lightening agents group (all P < 0.05), while there was no significant difference in the efficacy between the oral tranexamic acid group and the AHA chemical peeling group ( P > 0.05). After adjustment for potential confounders in the multivariate linear regression model, the oral tranexamic acid group (β = 2.64) and AHA chemical peeling group (β = 1.55) still showed significantly superior efficacy compared to the topical 2% hydroquinone group (both P < 0.05) ; the skin type Ⅳ group exhibited significantly superior efficacy compared to the skin type Ⅲ group (β = 1.87, P < 0.001) . Conclusions:Dark skin color, lack of sun protection habits, epidermal melasma, and mandibular-type melasma, and periorbital involvement were associated factors for the severity of melasma. Oral tranexamic acid and AHA chemical peeling appeared to exhibit superior efficacy compared to topical 2% hydroquinone cream and topical non-hydroquinone skin-lightening agents.

Acquired dermal macular hyperpigmentation (ADMH) is a group of diseases clinically characterized by grayish-black macules and patches, with pigment predominantly deposited in the dermis. ADMH includes Riehl's melanosis, lichen planus pigmentosus, and erythema dyschromicum perstans/ashy dermatosis. In light of the remarkable similarities in both morphological and histopathological characteristics among this group of diseases, the academic community has recently proposed the new nosological term "acquired dermal macular hyperpigmentation" to achieve integration and unified classification of these related disorders. This review comprehensively elaborates on advances in the diagnosis and treatment of ADMH, including clinical manifestations, dermoscopic findings, pathological characteristics, and treatment progress.

Given the increasing concern regarding antibacterial resistance, the antimicrobial properties of naphthoquinones have recently attracted significant attention. While 1,4-naphthoquinone and its derivatives have been extensively studied, the antibacterial properties of 5,8-dihydroxy-1,4-naphthoquinone derivatives remain relatively unexplored. This study presents a comprehensive in vitro and in vivo analysis of the antibacterial activity of 35 naturally sourced and chemically synthesized derivatives of 5,8-dihydroxy-1,4-naphthoquinone. Kirby-Bauer antibiotic testing identified three compounds with activity against methicillin-resistant Staphylococcus aureus (MRSA), with one compound (PNP-02) demonstrating activity comparable to vancomycin in minimum inhibitory concentration, minimum bactericidal concentration (MBC), and time-kill assays. Microscopic and biochemical analyses revealed that PNP-02 adversely affects the cell wall and cell membrane of MRSA. Mechanistic investigations, including proteomic sequencing analyses, Western blotting, and RT-qPCR assays, indicated that PNP-02 compromises cell membrane integrity by inhibiting arginine biosynthesis and pyrimidine metabolism pathways, thereby increasing membrane permeability and inducing bacterial death. In an in vivo mouse model of skin wound healing, PNP-02 exhibited antibacterial efficacy similar to vancomycin. The compound demonstrated low toxicity to cultured human cells and in hemolysis assays and remained stable during serum incubation. These findings suggest that PNP-02 possesses promising bioactivity against MRSA and represents a potential novel antibacterial agent.

ObjectiveTo observe the efficacy and safety of Zhuyuwan in the treatment of hyperlipidemia （syndrome of phlegm turbidity and obstruction） complicated with carotid atherosclerosis. MethodsA total of 120 patients with hyperlipidemia （syndrome of phlegm turbidity and obstruction） complicated with carotid atherosclerosis were randomly allocated into a treatment group and a control group， with 60 patients in each group. The control group orally took rosuvastatin calcium tablets， 10 mg each time， once a day. The treatment group took Zhuyuwan granules， 1 dose a day in 3 times. Both groups received diet and exercise guidance and were treated for 24 consecutive weeks. The traditional Chinese medicine （TCM） symptom scores were recorded before and after treatment. The levels of blood lipids ［total cholesterol （TC）， triglycerides （TG）， low-density lipoprotein cholesterol （LDL-C）， and high-density lipoprotein cholesterol （HDL-C）］， carotid color ultrasound ［carotid intima-media thickness （IMT）， plaque number， maximum plaque area， and maximum plaque thickness］， vascular intimal repair-related factors ［nitric oxide （NO）， endothelin-1 （ET-1）， soluble intercellular adhesion molecule 1 （sICAM-1）， and thromboxane B2 （TXB2）］， and oxidative stress-related indicators ［superoxide dismutase （SOD） and glutathione peroxidase （GSH-Px）］ were measured before and after treatment. The occurrence of adverse reactions was observed during treatment， and the clinical efficacy of the two groups was compared after treatment. ResultsThe trial was completed and 112 patients （57 in the treatment group and 55 in the control group） were included in the statistical analysis， and the general information of the two groups was comparable. The total response rate in the treatment group was 87.72% （50/57）， which was higher than that （74.55%， 41/55） in the control group （χ²=4.823， P<0.05）. After treatment， the scores of main TCM symptoms such as body obesity， chest tightness， and limb numbness， the scores of secondary symptoms such as palpitation， insomnia， tastelessness in the mouth， reduced appetite， tongue and pulse manifestation scores， and the total TCM symptom score decreased in both groups （P<0.05， P<0.01）. Moreover， the treatment group had lower scores of main symptoms such as body obesity， head heaviness， chest tightness， nausea， salivation， and limb numbness， scores of secondary symptoms such as tastelessness in the mouth and reduced appetite， and total TCM symptom score than the control group （P<0.05， P<0.01）. After treatment， both groups showed declines in TC， TG， LDL-C， IMT， plaque number， maximum plaque area， maximum plaque thickness， ET-1， sICAM-1， and TXB2 （P<0.05， P<0.01） and elevations in levels of HDL-C， NO， and SOD （P<0.05， P<0.01）. The treatment group had lower TC， TG， LDL-C， IMT， plaque number， maximum plaque area， maximum plaque thickness， ET-1， sICAM-1， and TXB2 （P<0.01） and higher levels of HDL-C， NO， SOD， and GSH-Px （P<0.05， P<0.01） than the control group. During treatment， adverse reactions occurred in 3 cases （5.26%， 1 case of dizziness， 1 case of acid reflux， and 1 case of constipation） in the treatment group and 4 cases （7.27%， 2 cases of upper respiratory tract infection， 1 case of abdominal pain， and 1 case of low back pain） in the control group. ConclusionZhuyuwan can effectively reduce blood lipid levels， inhibit the formation of carotid atherosclerotic plaque， and alleviate the syndrome of phlegm turbidity and obstruction by promoting vascular intima repair and improving the antioxidant function.
