Objective:To evaluate the efficacy and safety of narrow-band intense pulsed light in the treatment of erythromelanosis follicularis faciei et colli (EFFC).Methods:The patients with EFFC, diagnosed at the Department of Cosmetic Laser Surgery, Hospital for Skin Disease, Chinese Academy of Medical Sciences, and Peking Union Medical College, from January 2017 to December 2022, were retrospectively evaluated. There were 28 patients, including 24 males and 4 females. They ranged in age from 15 to 35 (21.0±4.2) years. All patients received three sessions of narrow-band intense pulsed light treatments, with intervals of 1-2 months. A follow-up visit was completed 1-2 months after three treatments, and efficacy was evaluated. Two dermatologists assessed the clinical improvement in erythema, pigmentation, and follicular papules on a 4-point scale (0=0-25% improvement, 1=26%-50% improvement, 2=51%-75% improvement, and 3=76%-100% improvement). Adverse events were also recorded.Results:A total of 28 patients received three sessions of narrow-band intense pulsed light treatments and were followed-up. After three treatments, the mean improvement scores for erythema, follicular papules, and pigmentation were (2.02±0.65), (1.38±0.59) and (0.80±0.61) respectively. Among these patients, 67.9% (19/28) experienced over 50% improvement in erythema, 39.3% (11/28) showed over 50% improvement in follicular papules, and 7.1% (2/28) demonstrated over 50% improvement in pigmentation. No blisters and scars were formed.Conclusions:Narrow-band intense pulsed light is a safe and effective treatment for patients with EFFC, particularly for those presenting with erythema.

Pregnancy in patients with Eisenmenger syndrome (ES) is associated with high maternal mortality rates of 30%‒50%, or even up to 65% in the case of a cesarean section (Yuan, 2016). Here, we report a case of term pregnancy complicated with ES and severe pulmonary artery hypertension (PAH), which was managed by a multidisciplinary team (MDT) and resulted in an uncomplicated delivery via elective cesarean section. The goal of this study is to emphasize the importance of multidisciplinary approach in the management of pregnancy with ES, which can profoundly improve maternal and infant outcomes.

Objective:To investigate the effect of miRNA (miR) -193b-5p on melanogenesis and its possible mechanisms.Methods:Human primary melanocytes were isolated from discarded normal foreskin tissues of healthy males after circumcision, and cultured in vitro. miR-NC mimics (miR-NC mimic group) and miR-193b-5p mimics (miR-193b-5p mimic group) were transfected into human primary melanocytes and human MNT1 melanoma cells, separately. After transfection, real-time quantitative PCR (RT-qPCR) was performed to determine the overexpression efficiency of miR-193b-5p at 48 hours, Western blot analysis to determine the expression of melanogenesis-related proteins tyrosinase (TYR) and microphthalmia-associated transcription factor (MITF) in human primary melanocytes and human MNT1 melanoma cells at 72 hours, and the melanin content in the above cells was determined by a sodium hydroxide solubilization method at 1 week. The target gene of miR-193b-5p was predicted by using Targetscan algorithms and verified by dual-luciferase reporter assay, and RT-qPCR and Western blot analysis were performed to analyze changes in mRNA and protein expression of the target gene respectively after the overexpression of miR-193b-5p. Two-independent-samples t test was used for comparisons between two groups. Results:In human primary melanocytes and human MNT1 melanoma cells, the miR-193b-5p expression levels were significantly higher in the miR-193b-5p mimic groups than in the miR-NC mimic groups ( t = 65.57, 22.49, respectively, both P < 0.001) , and the melanin content was significantly lower in the miR-193b-5p mimic groups (0.091 ± 0.007, 0.130 ± 0.004, respectively) than in the miR-NC mimic groups (0.117 ± 0.002, 0.188 ± 0.032, t = 5.98, 3.24, P < 0.01, < 0.05, respectively) . Western blot analysis showed that the expression of melanogenesis-related proteins TYR and MITF in both human primary melanocytes and human MNT1 melanoma cells was significantly lower in the miR-193b-5p mimic groups than in the miR-NC mimic groups (all P < 0.01) . TargetScan analysis and dual-luciferase reporter assay revealed a binding site for miR-193b-5p in the 3′ untranslated region of the transcriptional regulator CITED2. After up-regulation of miR-193b-5p expression in human primary melanocytes and human MNT1 melanoma cells, the CITED2 mRNA and protein expression levels significantly decreased compared with the miR-NC mimic groups (all P < 0.05) . Conclusion:miR-193b-5p overexpression can down-regulate the expression of melanogenesis-related proteins TYR and MITF, and then inhibit melanogenesis, which may be related to the targeted inhibition of CITED2 expression.

From February 1 to April 30, 2021, 48 general practice resident physicians in the First Affiliated Hospital of Naval Medical University were randomly divided into study group and control group with 24 in each group. The common comorbidities of the community-dwelling elderly, namely diabetes, diabetic retinopathy and osteoporosis were selected as teaching cases. The residents in control group received conventional teaching, while the scenario simulation teaching model of multicomorbity co-treatment was applied for the study group. The teaching effect, satisfaction and self-efficacy scores were compared between two groups. After training, the knowledge levels, the mastery of referral indicators and the performance of fundus ophthalmoscopy in the study group were significantly better than those in the control group ( t=2.27, 6.34, 4.09; P<0.05). They were (80.96±11.27) vs. (73.96±10.09), (10.33±2.41) vs. (6.38±1.88), (70.27±10.44) vs. (63.50±7.98), and students′ satisfaction and self-efficacy evaluation were higher than those of the observation group (all P<0.05). It is suggested that the simulation teaching of multi-disease co-treatment scenario is more beneficial than the traditional teaching to improve the comprehensive care ability of standardized training physicians in general practice for patients with chronic disease.

The coronavirus disease 2019 (COVID-19) pandemic has stimulated tremendous efforts to develop therapeutic agents that target severe acute respiratory syndrome coronavirus 2 to control viral infection. So far, a few small-molecule antiviral drugs, including nirmatrelvir-ritonavir (Paxlovid), remdesivir, and molnupiravir have been marketed for the treatment of COVID-19. Nirmatrelvir-ritonavir has been recommended by the World Health Organization as an early treatment for outpatients with mild-to-moderate COVID-19. However, the existing treatment options have limitations, and effective treatment strategies that are cost-effective and convenient for tackling COVID-19 are still needed. To date, four domestically developed oral anti-COVID-19 drugs have been granted conditional market approval in China. These drugs include azvudine, simnotrelvir-ritonavir (Xiannuoxin), leritrelvir, and mindeudesivir (VV116). Preclinical and clinical studies have explored the efficacy and tolerability of mindeudesivir and supported its early use in mild-to-moderate COVID-19 cases at high risk for progression. In this review, we discuss the most recent findings regarding the pharmacological mechanism and therapeutic effects focusing on mindeudesivir and other small-molecule antiviral agents for COVID-19. These findings will expand our understanding and highlight the potential widespread application of China's homegrown anti-COVID-19 drugs.

A new definition of metabolic dysfunction-associated fatty liver disease (MAFLD) has recently been proposed. We aim to examine the associations of MAFLD, particularly its discordance from non-alcoholic fatty liver disease (NAFLD), with the progression of elevated brachial-ankle pulse wave velocity (baPWV) and albuminuria in a community-based study sample in Shanghai, China. After 4.3 years of follow-up, 778 participants developed elevated baPWV and 499 developed albuminuria. In comparison with the non-MAFLD group, the multivariable adjusted odds ratio (OR) of MAFLD group for new-onset elevated baPWV was 1.25 (95% confidence interval (CI) 1.01-1.55) and 1.35 (95% CI 1.07-1.70) for albuminuria. Participants without NAFLD but diagnosed according to MAFLD definition were associated with higher risk of incident albuminuria (OR 1.77; 95% CI 1.07-2.94). Patients with MAFLD with high value of hepamet fibrosis score or poor-controlled diabetes had higher risk of elevated baPWV or albuminuria. In conclusion, MAFLD was associated with new-onset elevated baPWV and albuminuria independently of body mass index, waist circumference, and hip circumference. Individuals without NAFLD but diagnosed as MAFLD had high risk of albuminuria, supporting that MAFLD criteria would be practical for the evaluation of long-term risk of subclinical atherosclerosis among fatty liver patients.

Autism spectrum disorder (ASD) is a neurodevelopmental disorder, and its prevalence has been increasing during the recent years, which has posed a great impact on the families of the patients and society. Epidemiological studies have found that environmental exposure factors have an important impact on the occurrence and development of ASD, including pesticides, heavy metals, poly- and perfluoroalkyl substances, phenols, and air pollution. This paper focused on the relationship between environmental exposure to the above mentioned typical environmental exposure factors and the occurrence of ASD, in order to provide reference for related research of ASD.

Tumor-targeted immunotherapy is a remarkable breakthrough, offering the inimitable advantage of specific tumoricidal effects with reduced immune-associated cytotoxicity. However, existing platforms suffer from low efficacy, inability to induce strong immunogenic cell death (ICD), and restrained capacity of transforming immune-deserted tumors into immune-cultivated ones. Here, an innovative platform, perfluorooctyl bromide (PFOB) nanoemulsions holding MnO₂ nanoparticles (MBP), was developed to orchestrate cancer immunotherapy, serving as a theranostic nanoagent for MRI/CT dual-modality imaging and advanced ICD. By simultaneously depleting the GSH and eliciting the ICD effect via high-intensity focused ultrasound (HIFU) therapy, the MBP nanomedicine can regulate the tumor immune microenvironment by inducing maturation of dendritic cells (DCs) and facilitating the activation of CD8⁺ and CD4⁺ T cells. The synergistic GSH depletion and HIFU ablation also amplify the inhibition of tumor growth and lung metastasis. Together, these findings inaugurate a new strategy of tumor-targeted immunotherapy, realizing a novel therapeutics paradigm with great clinical significance.
