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.

OBJECTIVE: To observe the effects of Tongdu Tiaoshen acupuncture (for unblocking the obstruction in the governor vessel and regulating the spirit) on depression-like behavior and the hippocampal Endophilin A1/reactive oxygen species (ROS) pathway in the chronic unpredictable mild stress (CUMS) model rats, and explore the mechanism of this therapy for depression. METHODS: Forty-eight male SD rats of SPF grade were randomly divided into a normal group (n=12) and a modeling group (n=36). In the modeling group, CUMS was performed to establish depression model. The successfully-modeled rats were randomized into a model group, a Tongdu Tiaoshen acupuncture group (referred to as the acupuncture group), and a fluoxetine group, with 12 rats in each group. In the acupuncture group, "Baihui" (GV20), "Shenting" (GV24), "Shuigou" (GV26) and "Dazhui" (GV14) were stimulated with acupuncture. This intervention measure was delivered once a day, continuously for 6 days; it was discontinued on day 7 and was completed in 28 days. In the fluoxetine group, intragastric administration was done with fluoxetine solution (2.1 mg/kg), once a day, and for 28 consecutive days. Before and after modeling, and after intervention completion, the body mass, sucrose preference rate and the total distance of movement and the boxes of horizontal crossing in the open field experiment were observed in each group. After intervention, using HE staining, the hippocampal neuron morphology was observed; using Nissl staining, the hippocampal Nissl body number was counted. The hippocampal mitochondria was observed under transmission electron microscopy. The average fluorescence intensity of ROS in hippocampal was determined using flow cytometry. With Western blot method, the protein expression of Endophilin A1, growth associated protein 43 (GAP-43), and brain-derived neurotrophic factor (BDNF) in hippocampal was detected; and with RT-qPCR method, the mRNA expression of Endophilin A1, GAP-43, and BDNF was recorded. Using the immunofluorescence, the average fluorescence intensity of Endophilin A1, GAP-43, and BDNF in hippocampal tissue was determined. RESULTS: Compared with the normal group, in the model group, the body mass, sucrose preference rate, and the total distance of movement and the boxes of horizontal crossing in the open field experiment decreased (P<0.01); the hippocampal neuronal structure was unclear, the matrix was relatively loose, and the number of Nissl body decreased (P<0.01); mitochondrial structure was disarranged, the outer membrane was ruptured, mitochondrial cristae was irregular or missed; the average fluorescence intensity of ROS in hippocampal tissue, the protein and mRNA expression and the average fluorescence intensity of Endophilin A1 in hippocampal tissue increased (P<0.01), while the protein and mRNA expression of GAP-43 and BDNF and its average fluorescence intensity decreased (P<0.01). Compared with the model group, the acupuncture group and the fluoxetine group showed the increase in body mass, sucrose preference rate, the total distance of movement and the boxes of horizontal crossing in the open field experiment (P<0.05, P<0.01); the hippocampal neuronal structure became relatively clear, the matrix was relatively dense, and the number of Nissl body was elevated (P<0.01); mitochondrial structure got normal and disarranged slightly, the average fluorescence intensity of ROS in hippocampal tissue, the protein and mRNA expression and the average fluorescence intensity of Endophilin A1 in hippocampal tissue were reduced (P<0.01), while the protein and mRNA expression of GAP-43 and BDNF and the average fluorescence intensity rose (P<0.01, P<0.05). Compared with the fluoxetine group, the acupuncture group presented the increase in the average fluorescence intensity of ROS, the protein expression and the average fluorescence intensity of Endophilin A1, the protein expression of GAP-43 and the mRNA expression of BDNF (P<0.01, P<0.05), and the decrease of the protein expression and the average fluorescence intensity of BDNF, the mRNA expression of Endophilin A1, and the average fluorescence intensity of GAP-43 (P<0.01, P<0.05). CONCLUSION Tongdu tiaoshen acupuncture alleviates depression-like behaviors in CUMS model rats and protects hippocampal neurons, which may be related to suppressing Endophilin A1/ROS signaling pathway and attenuating oxidative stress reactions.

Objective:To explore the clinical changes in levels of the new clinical marker serum hepatitis B virus (HBV) pregenomic RNA (pgRNA) in patients with chronic hepatitis B (CHB) with long-term antiviral therapy.Methods:100 CHB cases who were initially treated with nucleos(t)ide analogues (NAs) at Peking University First Hospital were included. The levels of alanine aminotransferase (ALT), HBV DNA, hepatitis B e-antigen (HBeAg), and hepatitis B surface antigen (HBsAg) during the follow-up period were measured. The TaqMan-based real-time quantitative PCR method was used to detect serum HBV pgRNA levels. The independent sample t-test and Mann-Whitney U test were used to compare continuous variables between groups, while Pearson's χ2 test and Fisher's exact test were used to compare categorical variables. Results:HBV pgRNA levels decreased significantly in patients who developed virological responses at 48 weeks ( n = 54) during subsequent treatment compared to those who did not ( n = 46). The HBV pgRNA level was lower in HBeAg-positive patients than in HBeAg-negative patients ( P < 0.05 or P < 0.01). Patients with higher HBV DNA and HBeAg-positivity levels at baseline had a higher HBV pgRNA level following antiviral therapy. There was no statistically significant difference in HBV pgRNA levels in patients with different HBV pgRNA levels at baseline after antiviral therapy. There was no correlation between serum HBV pgRNA and HBsAg at baseline, but there was a correlation after long-term antiviral therapy, while there was a weak correlation between HBV pgRNA and HBsAg at the fifth and ninth years of antiviral therapy ( r = 0.262, P = 0.031; r = 0.288, P = 0.008). Conclusion:HBV pgRNA levels were higher with higher HBV activity in CHB patients with long-term antiviral 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.

Objective:To explore the influence of perceived stress on bedtime procrastination in college students,as well as the mediating role of daily ego-depletion and the moderating effect of guilt.Methods:The Per-ceived Stress Scale(PSS-4),State Self-Control Scale(SSCCS)and Bedtime Procrastination Scale(BPS)were used to track the daily perceived stress,ego-depletion and sleep procrastination of 34 college students for 14 days.The 1-1-1 and 2-1-1 multi-layer linear models were constructed by HLM to test the mediating and mod-erating effects.Results:Daily ego-depletion scores played a mediating role in the influence of daily perceived stress scores on daily bedtime procrastination scores(γ20=0.49,P＜0.001),guilt scores moderated the effect of daily ego-depletion scores on daily bedtime procrastination scores(γ11=0.03,P＜0.05).Conclusion:Daily perceived stress could not only directly predict bedtime procrastination on the night in college students,but also indirectly af-fect daily bedtime procrastination through daily ego-depletion.When ego-depletion is high,guilt can reduce college students'bedtime procrastination.

In recent years, researchers have found that patients with nonalcoholic fatty liver disease (NAFLD) often have urolithiasis, and the incidence of urolithiasis increases gradually with the severity of NAFLD. Meanwhile, the detection rate of NAFLD was higher in patients with urolithiasis than in normal controls. In this paper, we reviewed the domestic and international studies on the correlation between urolithiasis and NAFLD and described the related pathogenesis, such as insulin resistance, oxidative stress, abnormal lipid metabolism and impaired glyoxalate detoxification. Meanwhile, this paper proposed preventive measures to reduce the risk of development and recurrence of NAFLD-associated urolithiasis by addressing the common risk factors of both diseases, including metabolism-related diseases, lifestyle and diet.

Objective To investigate the serum levels of soluble programmed death-1 (sPD-1) and soluble programmed death-ligand 1 (sPD-L1) in chronic hepatitis B (CHB) patients with clinical cure, the correlation between programmed death-1 (PD-1) and lymphocytes by flow cytometry, and the recovery of hepatitis B virus (HBV)-specific immunity. Methods A total of 26 CHB patients with clinical cure, 26 treatment-naïve CHB patients, and 26 healthy controls who were diagnosed at the outpatient service of Peking University First Hospital from January to May of 2022 were enrolled, and related clinical data and peripheral blood samples were collected. ELISA was used to measure the serum levels of sPD-1 and sPD-L1, and flow cytometry was used to measure the expression of PD-1 in peripheral blood lymphocytes. CHB patients with clinical cure were compared with the treatment-naïve CHB patients and the healthy controls. The Kruskal-Wallis H test was used for comparison of non-normally distributed continuous data between three groups, and the chi-square test was used for comparison of categorical data between groups. The Pearson correlation analysis or the Spearman correlation analysis was used to investigate the correlation between two continuous variables. Results For the 26 CHB patients with clinical cure, the mean time of antiviral therapy was 8.33 years, with entecavir as the antiviral drug. The CHB patients with clinical cure had significantly higher levels of sPD-1 and sPD-L1 than the healthy controls ( P < 0.05) and significantly lower percentages of PD-1 + cells/lymphocytes and PD-1 + CD8 + T cells/lymphocytes than the treatment-naïve CHB patients ( P < 0.05). In the treatment-naïve CHB patients, the serum levels of sPD-1 and sPD-L1 were moderately negatively correlated with HBsAg level ( r =-0.524 and -0.583, both P < 0.05). The serum levels of sPD-1 and sPD-L1 were moderately positively correlated with PD-1 + CD8 + T cells/lymphocytes ( r =0.535 and 0.419, both P < 0.05). In the CHB patients with clinical cure, the serum levels of sPD-1 and sPD-L1 were not correlated with age, sex, alanine aminotransferase, T cells/lymphocytes, CD8 + T cells/lymphocytes, PD-1 + T cells/lymphocytes or PD-1 + CD8 + T cells/lymphocytes (all P > 0.05). Conclusion The serum levels of sPD-1 and sPD-L1 in treatment-naïve CHB patients are mainly associated with exhausted CD8 + T cells in peripheral blood, while there is no significant correlation between serum sPD-1/sPD-L1 and exhausted CD8 + T cells in peripheral blood in CHB patients with clinical cure.
