Purpose: This study evaluated a school-based mental health program within a psychiatry clerkship to enhance medical students’ competencies in mental health literacy, empathy, communication, and adaptability. The program aimed to bridge theoretical knowledge with practical skills through experiential learning in a real-world, community-based setting. Methods: The study utilized convenience sampling to select 32 medical students from the 2023–2024 psychiatry clerkship cohort. Four focus group discussions, each lasting 60–90 minutes, provided qualitative data, which were analyzed using reflexive thematic analysis in Atlas.ti (ATLAS.ti GmbH, Germany) to identify themes related to professional development. Results: Five key themes emerged, highlighting significant gains in context-sensitive communication, empathy, and mental health literacy specific to adolescent issues. The students reported increased clinical confidence, enhanced resilience through psychological techniques such mindfulness and motivational interviewing, and benefited from sustained engagement and peer support, fostering collaboration and stress management. Conclusion The school-based mental health program enhanced essential competencies in mental health literacy, empathy, communication, and practical skills for medical students. By integrating experiential learning into medical education, the program addressed training gaps, equipping future healthcare providers with the skills necessary for holistic and patient-centered mental healthcare across diverse clinical settings. The approach showed potential for broader applications in medical education to prepare students for comprehensive mental health support skills.

The extracellular domain (p75ECD) of p75 neurotrophin receptor (p75NTR) antagonizes Aβ neurotoxicity and promotes Aβ clearance in Alzheimer's disease (AD). The impaired shedding of p75ECD is a key pathological process in AD, but its regulatory mechanism is largely unknown. This study was designed to investigate the presence and alterations of naturally-occurring autoantibodies against p75ECD (p75ECD-NAbs) in AD patients and their effects on AD pathology. We found that the cerebrospinal fluid (CSF) level of p75ECD-NAbs was increased in AD, and negatively associated with the CSF levels of p75ECD. Transgenic AD mice actively immunized with p75ECD showed a lower level of p75ECD and more severe AD pathology in the brain, as well as worse cognitive functions than the control groups, which were immunized with Re-p75ECD (the reverse sequence of p75ECD) and phosphate-buffered saline, respectively. These findings demonstrate the impact of p75ECD-NAbs on p75NTR/p75ECD imbalance, providing a novel insight into the role of autoimmunity and p75NTR in AD.

AIM:To observe the effect of implantable collamer lens V4c(ICL V4c)implantation on high myopia, and the changes in anterior segment morphology.METHODS:A prospective study was conducted on 100 patients(200 eyes)with high myopia who were treated with ICL V4c implantation in the hospital from February 2018 to March 2021. The best corrected visual acuity(BCVA), uncorrected visual acuity(UCVA), intraocular pressure, higher-order aberration, anterior segment morphology [iridocorneal angle(ICA), central anterior chamber depth(ACD), anterior chamber volume(ACV), central corneal thickness(CCT)and K-value(K)], photopic and scotopic contrast sensitivity before operation and 6 and 12mo after operation were comparatively analyzed.RESULTS:All patients were followed-up. UCVA and BCVA were significantly improved at 6 and 12mo after operation(P<0.05). Total higher-order aberration, horizontal coma and vertical coma showed no significant difference before and after operation(P>0.05). Spherical aberration, ICA, ACD and ACV at 6 and 12mo after operation were significantly smaller than those before operation(P<0.05). Under photopic state, the contrast sensitivity of 3.0 and 6.0 c/d was significantly higher at 6 and 12mo after operation when compared with that before operation(P<0.05). Under scotopic state, the contrast sensitivity of 6.0 c/d was significantly higher at 6 and 12mo after operation when compared with that before operation(P<0.05); there was no significant difference in CCT, K, or intraocular pressure before and after operation(P>0.05).CONCLUSION:Although ICA, ACD and ACV in patients with high myopia are reduced after ICL V4c implantation, the operation can effectively improve visual acuity and visual quality.

Objective: To analyze the course of disease and epidemiological parameters of COVID-19 and provide evidence for making prevention and control strategies. Methods: To display the distribution of course of disease of the infectors who had close contacts with COVID-19 cases from January 1 to March 15, 2020 in Guangdong Provincial, the models of Lognormal, Weibull and gamma distribution were applied. A descriptive analysis was conducted on the basic characteristics and epidemiological parameters of course of disease. Results: In total, 515 of 11 580 close contacts were infected, with an attack rate about 4.4%, including 449 confirmed cases and 66 asymptomatic cases. Lognormal distribution was fitting best for latent period, incubation period, pre-symptomatic infection period of confirmed cases and infection period of asymptomatic cases; Gamma distribution was fitting best for infectious period and clinical symptom period of confirmed cases; Weibull distribution was fitting best for latent period of asymptomatic cases. The latent period, incubation period, pre-symptomatic infection period, infectious period and clinical symptoms period of confirmed cases were 4.50 (95%CI:3.86-5.13) days, 5.12 (95%CI:4.63-5.62) days, 0.87 (95%CI:0.67-1.07) days, 11.89 (95%CI:9.81-13.98) days and 22.00 (95%CI:21.24-22.77) days, respectively. The latent period and infectious period of asymptomatic cases were 8.88 (95%CI:6.89-10.86) days and 6.18 (95%CI:1.89-10.47) days, respectively. Conclusion: The estimated course of COVID-19 and related epidemiological parameters are similar to the existing data.

Objective:To explore the role of macrophage polarization on pericyte-to-myofibroblast transition and renal allograft fibrosis after kidney transplantation(KT).Methods:Allograft tissues were harvestedfrom recipients with chronic allograft dysfunction(CGD)and normal kidney tissues.The expression and distribution of M1/M2 macrophages in kidney tissues were detected by routine and immunofluorescent staining; mRNA of CD68, CD206 and iNOS detected by polymerase chain reaction(PCR); Murine vascular pericytes subjected to TGF-β1 in vitro and the expressions of α-SMA and PDGFR-β in perivascular cells detected by immunoblotting and cellular fluorescence; The co-culturing models of vascular pericytes and M1/M2 macrophages were constructed.The expressions of α-SMA and PDGFR-β in pericytes were detected by immunoblotting, cellular fluorescence and PCR.Results:A marked infiltration of CD68+ iNOS+ M1 macrophages was present in allograft tissues of recipients with CGD while no obvious infiltration of CD68 + CD206 + was observed.The mRNA levels of CD68, iNOS and CD206 were significantly higher in CGD group than those in control group( P<0.05); In CGD allograft tissues, protein expressions of α-SMA and PDGFR-β spiked markedly( P<0.05)while cells with double staining of α-SMA and PDGFR-β were markedly infiltrated in interstitial area of CGD allograft.TGF-β1 could induce a marked elevation of PMT-related markers in a time-dependent manner( P<0.05); Immunoblotting and cellukar fluorescence indicated that M1 macrophages could promote the elevations of α-SMA and PDGFR-β in pericytes in vitro while M2 macrophages showed no effect on pericyte-to-myofibroblast transition in pericytes. Conclusions:M1 macrophage polarization may promote the formation of renal allograft interstitial fibrosis through promoting PMT.
