AIM: To systematically evaluate the efficacy and safety of low-concentrations atropine eye drops in controlling adolescent myopia.METHODS:A computer search was conducted on Wanfang Data, CNKI, VIP, PubMed, Cochrane Library, and Embase databases from January 2010 to March 2024 on clinical studies on low-concentration atropine eye drops for controlling adolescent myopia. Two researchers independently screened trials, extracted data, evaluated risk of bias and quality, and used Review Manager5.4 software to perform Meta-analysis.RESULTS:A total of 17 articles, involving 3 764 cases and 3 952 eyes, were included. The Meta-analysis showed that compared with the control group, low concentrations of atropine could effectively slow down the growth of axial length [MD=-0.15, 95% CI(-0.20, -0.10), P<0.00001], significantly controlled the changes in spherical equivalent [MD=0.39, 95% CI(0.29, 0.48), P<0.00001], and had a significant effect on pupil diameter [MD=0.80, 95% CI(0.33,1.28), P=0.0010] and amplitude of accommodation [MD=-2.54, 95%CI(-4.49, -0.60), P=0.01].CONCLUSION:Low-concentrations atropine are effective in controlling spherical equivalent and axial length of myopia in adolescents, significantly affecting pupil diameter and amplitude of accommodation, and effectively delaying the progression of myopia.

Objective:To investigate dietary patterns of individuals aged ≥50 in Shanghai and analyze their association with frailty.Methods:Using data from the third wave of the Study on Global Ageing and Adult Health in Shanghai conducted between 2018 and 2019. We collected the frequency and average intake of food by the food frequency questionnaire. Factor analysis was used to extract dietary patterns, and a frailty index was constructed using the ratio of the cumulative total score of health deficits to 35 health-related variables considered. We used an ordinal multinomial logistic regression model to analyze the association between dietary patterns and frailty.Results:A total of 3 274 participants aged (67.9±9.2) years were included in the study, including 1 971 (60.2%) men and 1 303 (39.8%) women. We extracted four dietary patterns: high-protein-nuts pattern, potato-bean-vegetable-fruit pattern, poultry-meat pattern, and high-oil-salt pattern. After adjusting for confounding factors, the logistic regression analysis showed that compared with the high-oil-salt pattern, the high-protein-nuts pattern was negatively associated with the risk of higher frailty ( OR=0.743, 95% CI: 0.580-0.951). We did not find an association between dietary patterns and frailty between the different gender groups. In the age group 50-64, the high-protein-nuts and potato-bean-vegetable-fruit patterns were negatively correlated with a higher degree of frailty than the high-oil-salt pattern. In the low-level physical activity group, the high-protein-nuts pattern was negatively correlated with a higher degree of frailty than the high-oil-salt pattern ( OR=0.509, 95% CI: 0.361-0.720). However, we found no significant effect of the high-protein nuts pattern, potato-bean-vegetable-fruit pattern, and poultry-meat pattern on the risk of higher frailty compared to the high-oil-salt pattern in the moderate to high level of physical activity group. Conclusions:Compared to the high-oil-salt pattern, dietary patterns with a higher intake of high-protein nuts, potatoes, legumes, and fruits and vegetables might be associated with a lower risk of higher frailty in residents aged 50-64 years of age than with a high oil and salt pattern. At the same time, it may have a more significant protective effect in people with lower physical activity levels. It is suggested that a diet rich in high-protein foods, nuts, potatoes, beans, vegetables, and fruits may help reduce and delay the risk of frailty.

Objective:To understand the association between vitamin D level and grip strength in people aged ≥50 years in Shanghai.Methods:Data were obtained from the WHO's Study on Global Ageing and Adult Health in Shanghai during 2018-2019. Logistic regression model was used to analyze the association between vitamin D level and grip strength, and a stratified analysis was conducted for different gender, age and dairy product intake groups. Restricted cubic spline was used to evaluate the dose-response association between vitamin D level and low grip strength.Results:A total of 4 391 participants were included in the study, including 2 054 men (46.8%), with an average age of (67.02±8.81) years. And 1 421 individuals (32.4%) had low grip strength; 1 533 individuals (34.9%) had vitamin D deficiency, and 401 individuals (9.1%) had vitamin D deficiency. After adjusted for confounding factors, the logistic regression results analysis showed that individuals with vitamin D deficiency had a higher risk for low grip strength ( OR=1.41, 95% CI: 1.09-1.83). In men, after adjusting for confounding factors, vitamin D deficiency was positively associated with the risk for low grip strength ( OR=1.67, 95% CI: 1.12-2.50), but there was no significant association between vitamin D level and grip strength in women ( OR=1.30, 95% CI: 0.97-1.74). In age group 60-69 years and ≥80 years, there was significant association between vitamin D deficiency and low grip strength after adjusting for confounding factors ( OR=1.57, 95% CI: 1.05-2.35; OR=2.40, 95% CI: 1.08-5.31). In people who had daily intake of dairy product <250 ml, there was positive association between vitamin D deficiency and low grip strength, but there was no significant association in people who had daily dairy product ≥250 ml after adjusting for confounding factors. The restrictive cubic spline demonstrated that risk of low grip strength might decreased with the increase of vitamin D levels, however, the difference was not significant ( P>0.05). Conclusions:This study demonstrated that there is association between vitamin D level and grip strength. People with vitamin D deficiency have higher risk for low grip strength.

Objective:To explore the HIV-1 drug resistance in patients with HIV/AIDS in Guilin city following the failure of antiretroviral treatment (ART).Methods:Plasma samples were collected from patients in Guilin who had received ART for more than 1 year and had a HIV viral load greater than or equal to 1 000 copies/ml from January 2019 to December 2023, and demographic information was also collected for HIV-1 genotype subtype analysis and drug resistance testing to determine the resistance mutation loci and the susceptibility of the strains to drugs.Results:A total of 766 patient samples with failed ART collection and successful amplification were collected, of which 536 (69.97%, 536/766) were male, with an average age of 53 years; a total of 8 HIV-1 subtypes were detected, with CRF01_AE (80.55%, 617/766), CRF07_BC (11.10%, 85/766) and CRF08_BC (6.92%, 53/766) predominated. The drug resistance analysis showed that the HIV-1 drug resistance rate was 34.86% (267/766), including nucleoside reverse transcriptase inhibitors (NRTIs), non-nucleoside reverse transcriptase inhibitors (NNRTIs) and protease inhibitor (PI), with dual resistance to NRTIs/NNRTIs (48.31%, 129/267) and NNRTIs resistance (43.07%, 115/267) predominantly. A total of 37 resistance mutation sites were detected, 14 NRTIs-associated mutation sites mainly included M184V/I (47.57%, 127/267), K65R (18.73%, 50/267), K70E/N/T/G/R (13.11%, 35/267), etc., and 18 NNRTIs-associated mutation sites mainly included K103 N/R (56.93%, 152/267), V179 D/E/T (21.72%, 58/267), G190C/S/Q (17.23%, 46/267), and V106I/M (16.85%, 45/267), etc.; and 5 PIs-associated mutation sites was the highest with L10V/I mutation rate (3.00%, 8/267).Conclusions:HIV/AIDS patients in Guilin have shown favorable outcomes in antiviral therapy, with a relatively low overall incidence of drug resistance. However, it is essential to enhance surveillance to reduce the spread of drug-resistant strains in the future.

Objective: To investigate the willingness to accept preventive treatments and its related factors among college freshmen with latent tuberculosis infection (LTBI), so as to provide the evidence for preventive treatment intervention measures for students with LTBI. Methods: Cluster sampling method was used to select 368 LTBI freshmen from 8 colleges and universities in Changzhou in September 2023, who conducted a questionnaire survey on the willingness to receive preventive treatment. General demographic data were collected and relevant data were collected using tuberculosis knowledge scale, General Anxiety Disorder-7 (GAD-7), Patient Health Questionnaire-9 (PHQ-9), Adaptation, Partnership, Growth, Affection and Resolve (APGAR), and a self developed Stigma Scale. A binary Logistic regression model was constructed with the willingness to accept preventive treatment as the dependent variable to analyze the willingness to accept preventive treatment and the influencing factors. Results: A total of 253 LTBI college freshmen were willing to take preventive treatment, the acceptance rate was 68.75%. The rate of willingness to accept preventive treatment for LTBI was higher among students whose fathers had an education level of high school, compared to those whose fathers had an education level of junior high school or below ( OR =2.16, P <0.05). LTBI students whose per capita family income was >5 000-10 000 yuan and >10 000 yuan were more willing to accept LTBI preventive treatment than those whose per capita family income was <3 000 yuan ( OR =2.72, 4.46, P <0.05). LTBI students who engaged in physical exercise for more than 2 hours per week were more willing to accept than those who exercised less than 0.5 hours per week ( OR =1.91, P <0.05). LTBI students with high levels of tuberculosis knowledge and stigma were more likely to receive preventive treatment ( OR =1.18, 1.11, P < 0.05). LTBI students with high PHQ-9 ( OR =0.85) and GAD-7 ( OR =0.92) scores were more likely to refuse preventive treatment ( P <0.05). Conclusion The present study revealed a moderate level of willingness of LTBI students to preventive treatment in Changzhou City, and the acceptance is affected by family factors, healthy lifestyles, tuberculosis knowledge and psychological status.

Objective:To discuss the clinical characteristics,diagnosis,and treatment of Shwachman-Diamond syndrome(SDS),and to enhance the clinicians'awareness of the disease.Methods:The clinical materials of one patient diagnosed with SDS,primarily presented with neutropenia and elevated transaminase levels,confirmed by genetic testing were retrospectively analyzed.The clinical manifestations,genetic features,diagnosis,and treatment methods of SDS were analyzed complemented with the relevant literatures.Results:This patient was a male child,aged 27 months.His initial clinical presentations were neutropenia and elevated transaminase levels.The patient had previously experienced diarrhea when the patient was 3 months old,which improved after treated with oral pancreatic enzyme dispersion.Over the past six months,the patient had recurrent respiratory infections.Upon admission,the examination results showed there was dental enamel hypoplasia,and the imaging results showed the abnormal bone density in the long bones of the limbs.The genetic sequencing results showed a homozygous mutation in the Shwachman-Bodian-Diamond syndrome(SBDS)gene(c.258+2T>C).During hospitalization,the patient received the hepatoprotective care and granulocyte augmentation supportive treatment,leading to an improvement in his condition,and the patient was discharged.During a one-year follow-up,the patient's condition was stable.Conclusion:The typical presentation of the SDS patient includes diarrhea,liver function abnormalities,hematologic abnormalities,and skeletal anomalies,particularly neutropenia;there may also be developmental delays and involvement of the heart,liver,central nervous system,skeleton,and immune system.The genetic testing of suspected children is crucial,and it can aid in the early diagnosis and treatment of SDS patients.

Objective To investigate the clinical diagnostic value of extra-spindle pole-like protein 1(ESPL1)in the progression of hepatitis B virus(HBV)-related liver fibrosis.Methods A total of 228 patients with HBV infection who were admitted to The First Affiliated Hospital of Guangxi Medical University from June 2017 to August 2023 were enrolled.The transient elastography system FibroScan was used to determine liver stiffness measurement(LSM)for all patients,and according to the LSM value,they were divided into non-liver fibrosis group with 80 patients,mild liver fibrosis group with 83 patients,advanced liver fibrosis group with 30 patients,and liver cirrhosis group with 35 patients.ELISA was used to measure the serum level of ESPL1.The Kruskal-Wallis H test was used for comparison of the serum level of ESPL1 between the four groups;the Spearman correlation analysis was used to investigate the correlation between ESPL1 and LSM;the receiver operating characteristic(ROC)curve was used to analyze the value of serum ESPL1 in predicting the progression of liver fibrosis.Results The liver cirrhosis group had a significantly higher serum level of ESPL1 than the non-liver fibrosis group and the mild liver fibrosis group(both P<0.05),and the advanced liver fibrosis group and the mild liver fibrosis group had a significantly higher serum level of ESPL1 than the non-liver fibrosis group(both P<0.05).The correlation analysis showed that there was a positive correlation between serum ESPL1 and LSM in the patients with HBV infection and varying degrees of liver fibrosis(r=0.515,P<0.001).Serum ESPL1 had an area under the ROC curve(AUC)of 0.809 in predicting liver cirrhosis and an AUC of 0.638 in predicting advanced liver fibrosis,with a sensitivity of 87.5%and 100%,respectively,and a specificity of 59.7%and 31.3%,respectively.Conclusion There is a certain correlation between serum ESPL1 and HBV-related liver fibrosis,and higher serum ESPL1 may indicate a higher degree of liver fibrosis.Serum ESPL1 is expected to become one of the serum markers for assisting in the diagnosis of liver cirrhosis and an important clinical method for dynamically monitoring the progression of liver fibrosis in patients with HBV infection.

Background Steel workers are exposed to occupational hazardous factors such as dust, noise, and heat, and often work in shifts, making them prone to sleep disorders. Objective To explore potential influencing factors of sleep disorders among workers in a steel enterprise in Gansu Province, and provide a basis for reducing the risk of sleep disorders among them. Methods From January to March 2022, a self-made questionnaire combined with the Pittsburgh Sleep Quality Index (PSQI) were used to investigate the employees of a steel enterprise in Gansu Province. According to their PSQI scores, they were divided into a normal sleep group and a sleep disorder group. The general demographic variables of the two groups were balanced by 1∶1 propensity score matching (PSM). Multiple logistic regression was used to analyze the contributing factors of sleep disorders. Restricted cubic spline (RCS) model was used to analyze potential dose-response relationship between weekly working hours and sleep disorders. Results The prevalence of sleep disorders in the steel workers was 48.06% (6029/12544). After PSM, 5847 pairs were successfully matched, and the distributions of matched variables were well balanced between the two groups. The results of multiple logistic regression showed that hypertension (OR=1.39, 95%CI: 1.24, 1.56), diabetes mellitus (OR=1.34, 95%CI: 1.07, 1.66), three-shift system (OR=1.26, 95%CI: 1.12, 1.41), dust exposure (OR=1.14, 95%CI: 1.01, 1.29), noise exposure (OR=1.23, 95%CI: 1.09, 1.39), heat exposure (OR=1.16, 95%CI: 1.04, 1.29), and work injury (OR=1.22, 95%CI: 1.02, 1.46) increased the risk of sleep disorders. Compared with workers with < 10 years of service, those with 10-20 years (OR=1.31, 95%CI: 1.19, 1.44), 20-30 years (OR=1.34, 95%CI: 1.19, 1.52), and ≥30 years of service (OR=1.35, 95%CI: 1.19, 1.53) had a higher risk of sleep disorders. Compared with non-exercise workers, the risk of developing sleep disorders was lower in workers with occasional exercise (OR=0.61, 95%CI: 0.56, 0.66) and regular exercise (OR=0.55, 95%CI: 0.49, 0.62). The RCS model showed that the weekly working hours and sleep disorders in the steel workers showed a nonlinear dose-response relationship (P<0.05 for overall trend, P<0.05 for nonlinear test). The relationship between weekly working hours and sleep disorders showed a "U" shaped distribution, with a significant increase in the risk of sleep disorders when the weekly working hours exceeded 49 h. Conclusion The non-occupational influencing factors of sleep disorders of employees in the steel enterprise include hypertension, diabetes, physical exercise, and occupational influencing factors include length of service, weekly working hours, shifts, dust exposure, noise exposure, heat exposure, and work injuries. It is recommended to consider both occupational and non-occupational factors to formulate appropriate sleep disorder prevention and control measures for steel employees to reduce the risk of sleep disorders.

Detailed characterizations of genomic alterations have not identified subtype-specific vulnerabilities in adult gliomas. Mapping gliomas into developmental programs may uncover new vulnerabilities that are not strictly related to genomic alterations. After identifying conserved gene modules co-expressed with EGFR or PDGFRA (EM or PM), we recently proposed an EM/PM classification scheme for adult gliomas in a histological subtype- and grade-independent manner. By using cohorts of bulk samples, paired primary and recurrent samples, multi-region samples from the same glioma, single-cell RNA-seq samples, and clinical samples, we here demonstrate the temporal and spatial stability of the EM and PM subtypes. The EM and PM subtypes, which progress in a subtype-specific mode, are robustly maintained in paired longitudinal samples. Elevated activities of cell proliferation, genomic instability and microenvironment, rather than subtype switching, mark recurrent gliomas. Within individual gliomas, the EM/PM subtype was preserved across regions and single cells. Malignant cells in the EM and PM gliomas were correlated to neural stem cell and oligodendrocyte progenitor cell compartment, respectively. Thus, while genetic makeup may change during progression and/or within different tumor areas, adult gliomas evolve within a neurodevelopmental framework of the EM and PM molecular subtypes. The dysregulated developmental pathways embedded in these molecular subtypes may contain subtype-specific vulnerabilities.
