ObjectiveTo observe the intervention effect of Fufang Kangjiaolv capsules on anxiety-like behaviors in the rat model of chronic restraint stress （CRS） and explore the mechanism underlying the anti-anxiety effect via the microbiota-gut-brain axis. MethodsRats were assigned into blank， model， positive drug （diazepam， 1 mg·kg^-1）， and low-， medium-， and high-dose （0.75， 1.5， 3 g·kg^-1， respectively） Fufang Kangjiaolv capsules groups. After 14 days of administration， the elevated plus maze test， open field test， light and dark box test， and marble burying test were performed. Hematoxylin-eosin staining was employed to observe the pathological changes in the hippocampus and colon of rats， and Nissl staining was conducted to observe the damage of hippocampal neurons. The gut microbiota was analyzed by 16S rRNA gene sequencing. Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） was employed to determine the mRNA levels of zonula occludens-1 （ZO-1） and occludin in the colon of rats. The levels of tumor necrosis factor-α （TNF-α）， interleukin-6 （IL-6）， and interleukin-1β （IL-1β） in the colon， serum， and hippocampus were determined by enzyme-linked immunosorbent assay. Western blot was employed to determine the protein levels of ZO-1， occludin， nuclear factor-κB p65 （NF-κB p65） in the colon tissue and NF-κB p65 and brain-derived neurotrophic factor （BDNF） in the hippocampal tissue. ResultsCompared with the blank group， the model group showed reductions in the time and frequency ratio of rats entering the elevated plus maze， the time and frequency of rats entering the central area of the open field， the time of entering the open box， the times of passing through the light and dark box， and the number of unburied beads （P<0.05， P<0.01）. Compared with the model group， Fufang Kangjiaolv capsules ameliorated the anxiety of the model rats to varying degrees， and the high-dose group had the best effect， with increases in the proportions of time and frequency of rats entering the open arm in the elevated plus maze （P<0.05）， the number of rats entering the central area in the open field （P<0.05）， the time of entering the open box， the times of passing through the light and dark boxes， and the number of unburied beads （P<0.01）. Moreover， the high-dose group showed alleviated pathological damage of hippocampal neurons and colon. The results of 16S rRNA gene sequencing showed that the model group had increased relative abundance of Firmicutes， Deferribacterota， Romboutsia， and Phascolarctobacterium， while it had decreased relative abundance of Bavcteroidota and Lactobacillus. The drug administration groups showed increased relative abundance of Bavcteroidota， Bacteroides， norank f norank o Clostridia UCG-014， and Blautia and decreased relative abundance of Firmicutes and Deferribacterota. Compared with the blank group， the model group showed down-regulated protein and mRNA levels of ZO-1 and occludin in the colon （P<0.01）， elevated levels of TNF-α， IL-6， and IL-β in the colon， serum， and hippocampus （P<0.01）， up-regulated protein level of NF-κB p65 in the colon and hippocampus （P<0.01）， and down-regulated protein level of BDNF in the hippocampus （P<0.05）. Compared with the model group， high-dose Fufang Kangjiaolv capsules up-regulated the mRNA levels of ZO-1 and occludin in the colon （P<0.01）， lowered the levels of TNF-α， IL-6， and IL-β in the colon， serum， and hippocampus （P<0.01）， up-regulated the protein levels of ZO-1 （P<0.01） and occludin （P<0.05） in the colon， down-regulated the protein level of NF-κB p65 in the colon and hippocampus （P<0.05）， and up-regulated the protein level of BDNF in the hippocampus. ConclusionFufang Kangjiaolv capsules can reduce the anxiety-like behaviors in the rat model of CRS by regulating the gut microbiota disturbance， up-regulating the expression of tight junction proteins in the colon， repairing intestinal mucosal mechanical barrier， and down-regulating NF-κB/BDNF signaling pathway， thereby reducing peripheral and central inflammation. This study proves the hypothesis that Fufang Kangjiaolv capsules play an anti-anxiety role via the microbiota-gut-brain axis， providing a new idea for further research.

AIM: To observe related influence of eye-use behaviors on the onset and progression of myopia among primary school student in Minhang district, Shanghai under the background of “double reduction”, and evaluate the impact of eye-use habit and behavior on the myopia development in children and adolescents.METHODS:A stratified cluster sampling method was adopted to select study subjects for longitudinal observation. Random sampling was conducted among grade 1-4 students from three primary schools in Minhang District, Shanghai from September to December 2021 after the implementation of the “double reduction” policy, with a 2-year observation period. Annual vision screenings were performed to obtain uncorrected visual acuity, non-cycloplegic refraction data, and spherical equivalent(SE). Biometric measurements were taken to acquire axial length(AL)and corneal curvature(CR). Questionnaires were administered to investigate the eye-use behaviors of participants. Taking myopia ≤-0.50 D as the diagnostic criterion, myopia incidence were calculated. SE and AL changes were used to evaluate myopia progression. Logistic regression analysis was employed to identify risk factors for myopia, and analyze the relationship between eye-use behaviors and myopia development or progression.RESULTS:A total of 2 986 children complete a follow-up for 2 a. The baseline prevalence of poor vision was 32.74%, increasing to 38.92% and 43.73% at 1 and 2 a follow-up, respectively, demonstrating a yearly upward trend. Taking uncorrected visual acuity combined with non-cycloplegic refraction as clinical screening criteria for myopia, the incidence was 24.72%, 27.60%, and 29.64% at baseline, 1, and 2 a follow-ups, respectively. These showed no statistical significant difference compared to the diagnostic standard of cycloplegic refraction SE(23.98%, 27.03%, and 29.17%; all P>0.05). Logistic regression analysis found that daily outdoor and sleep duration were protective factors against myopia(OR=0.54, 0.84, all P<0.05), while age, parental myopia, duration of offline education, online education, electronic device usage, and poor visual posture were identified as risk factors(OR=2.72, 1.54, 1.72, 1.12, 1.47, 1.26, all P<0.001). Further analysis of myopia progression in baseline myopic children over 2 a revealed that age, parental myopia, baseline SE, duration of offline/online education, electronic device usage, and poor visual posture may contribute to rapid myopia progression.CONCLUSION:Under the background of “double reduction”, the eye-use behavior among primary school students in Minhang District, Shanghai has an important impact on the occurrence and development of myopia. In order to effectively prevent and control myopia, it is necessary to further strengthen the education and guidance of eye-use behavior.

AIM: To compare the effectiveness of foldable capsular body(FCB)with traditional scleral buckling(SB)in the treatment of experimental retinal detachment animal models.METHODS: After successfully establishing rhegmatogenous retinal detachment(RRD)animal models, 24 New Zealand white rabbits were randomly divided into three groups(RRD models group, SB group, and FCB group), with 8 rabbits in each group. The FCB and SB groups underwent SB and FCB surgeries for the RRD animal models, while the RRD models group only consists of RRD models without any surgical intervention during the follow-up period. The follow-up duration was 3 mo. Wide-field neonatal fundus imaging system and ophthalmic B-ultrasound were used to assess the fundus conditions before and after surgery. The Icare® TONOVET Plus tonometer was utilized to evaluate intraocular pressure changes before and after surgery. The Eaton and Draize scoring systems were selected to monitor postoperative inflammatory reactions.RESULTS: The retinal reattachment rates in the FCB and SB groups were 87.5% and 75.0%, respectively, with no statistically significant difference between the groups(P>0.05). The intraocular pressure in both the FCB and SB groups increased postoperatively compared to preoperative levels(P<0.01), and there were no significant differences in intraocular pressure at any time points during the follow-up period between the groups(P>0.05). The intraocular pressure in the RRD models group remained at a low level throughout the follow-up period. The average surgical time for the FCB group was 16.87±2.29 min, which was shorter than 46.25±4.74 min in the SB group(t=-15.166, P<0.001). According to the Eaton and Draize scoring systems, the FCB group had lower grades of conjunctival hyperemia and edema in the early postoperative period compared to the SB group, indicating milder inflammatory reactions(P<0.05).CONCLUSION: Both FCB and SB are effective in treating experimental RRD. Compared to SB, FCB is simpler to operate, and also has a shorter surgical time and milder postoperative inflammatory reactions.

Nucleotide-binding oligomerization domain (NOD)-like receptor protein 3 (NLRP3) is a cytosolic pattern recognition receptor that recognizes multiple pathogen-associated molecular patterns and damage-associated molecular patterns. It is a cytoplasmic immune factor that responds to cellular stress signals, and it is usually activated after infection or inflammation, forming an NLRP3 inflammasome to protect the body. Aberrant NLRP3 inflammasome activation is reportedly associated with some inflammatory diseases and metabolic diseases. Recently, there have been mounting indications that NLRP3 inflammasomes play an important role in liver injuries caused by a variety of diseases, specifically hepatic ischemia/reperfusion injury, hepatitis, and liver failure. Herein, we summarize new research pertaining to NLRP3 inflammasomes in hepatic injury, hepatitis, and liver failure. The review addresses the potential mechanisms of action of the NLRP3 inflammasome, and its regulation in these liver diseases.

OBJECTIVES: The application of photodynamic therapy in solid tumors has attracted increasing attention in recent years, and the efficiency of photosensitizers is a crucial determinant of therapeutic efficacy. This study aims to evaluate the cytotoxic effects of a novel photosensitizer, PEG-MTPABZ-PyC, in photodynamic therapy against gastric cancer cells. METHODS: Gastric cancer MKN45 cells were treated with PEG-MTPABZ-PyC. A high-content live-cell imaging system was used to assess the cellular uptake kinetics and subcellular localization of the photosensitizer. The cytotoxic effects of PEG-MTPABZ-PyC-mediated photodynamic therapy were examined using the cell counting kit-8 (CCK-8) assay and flow cytometry, while the intrinsic cytotoxicity of the photosensitizer alone was verified by the CCK-8 assay. Intracellular reactive oxygen species (ROS) generation after photodynamic therapy was detected using 2'-7'-dichlorodihydrofluorescein diacetate (DCFH-DA). RESULTS: PEG-MTPABZ-PyC alone exhibited no cytotoxicity toward MKN45 cells, indicating excellent cytocompatibility. The compound efficiently entered cells within 6 hours and localized predominantly in lysosomes. Upon light irradiation, PEG-MTPABZ-PyC-mediated photodynamic therapy induced significant cytotoxicity compared with the control group (P<0.05) and generated abundant intracellular ROS. CONCLUSIONS The novel photosensitizer PEG-MTPABZ-PyC demonstrates potent photodynamic cytotoxicity against gastric cancer cells, showing promising potential for further development in gastric cancer photodynamic therapy.

Objective:To explore the application and research progress of lasers in the treatment of kidney neoplasms through an integrated bibliometric and Meta-analysis study.Methods:On June 7th, 2024, an online search of the Web of Science Core Collection (WoSCC) and China National Knowledge Infrastructure (CNKI) databases for all relevant literature on lasers in kidney neoplasms was conducted. The retrieved results were subjected to a comprehensive bibliometric analysis. The high-quality studies were then screened to further describe the clinical characteristics of patients who underwent laser-assisted laparoscopic partial nephrectomy (LLPN). Subsequently, a Meta-analysis was performed using RevMan 5.4.1 software on further selected high-quality studies to compare the changes in renal function before and after LLPN treatment, and the differences in efficacy between LLPN and traditional laparoscopic partial nephrectomy (LPN).Results:Our study obtained a total of 549 publications on lasers in kidney neoplasms, including 513 in English and 36 in Chinese. Bibliometric analysis revealed an overall upward trend in the annual publications and citations in this field. China was found to be a leading contributor ranking second in total publications ( n=100, 18.2%). The primary application of laser treatment was in nephron-sparing surgery for kidney neoplasms, especially in LPN. We further screened 11 high-quality studies comprising 284 patients who underwent LLPN for kidney neoplasms. Comprehensive descriptive statistical analysis was performed on clinical characteristics of the 284 patients. All patients had T 1a stage tumors with a mean tumor length of 2.6 cm (range: 0.8-4.0 cm), all being local, solitary, and exophytic tumors. Further Meta-analysis indicated that there were no significant differences in renal function indicators including both serum creatinine levels ( MD=4.52, 95% CI-9.73-0.69, P = 0.09) and estimated glomerular filtration rate ( MD=3.05, 95% CI-1.03-7.13, P= 0.14) before and after LLPN. Additionally, compared to traditional LPN, LLPN showed significantly reduced operative time ( MD=-10.58, 95% CI= -13.11-8.06, P<0.001), but no significant differences in estimated blood loss ( MD= -27.09, 95% CI-67.38-13.21, P=0.19) and hospital stay ( MD=-1.59, 95% CI-3.42-0.25, P=0.09). Conclusions:The application of lasers in managing of kidney neoplasms is arousing increasing attention among urologists. LLPN offers several advantages, including precise cutting and effective hemostasis. This technique demonstrates considerable clinical value for patients with exophytic T 1a kidney neoplasms undergoing "zero-ischemia" nephron-sparing surgery.
