Objective: To understand the prevalence of myopia among primary and secondary school students in minority areas of Yunnan Province, and to explore the influence of outdoor activities and short-distance use of eyes, so as to provide a basis for early myopia intervention. Methods: In October 2020, the survey was conducted among 1 782 primary and secondary school students in three cities of Yunnan through a multi stage random cluster sampling method. All subjects underwent a questionnaire survey and the visual acuity examination at baseline. The first follow-up was conducted in October 2021 to obtain 1 691 valid samples, and the second follow-up was conducted in May 2023 to obtain 1 367 valid samples. Factors associated with myopia among primary and secondary school students were explored by using generalized estimating equations. Results: The prevalence rates of myopia in 2020, 2021 and 2023 were 52.64%, 61.62% and 69.35%, respectively, showing an increasing trend ( χ 2 trend =91.77, P <0.05). The results of multivariate regression analysis on the generalized estimation equations showed that age at baseline ( OR =1.31), girls ( OR =1.76), Hani ethnicity ( OR =0.75), Bai ethnicity ( OR =0.69), parental myopia ( OR =1.97-2.29), parents often reducing children s exercise time for homework or tutoring ( OR =1.35), less than 1 time or 2-3 times of ball sports per week ( OR =1.27, 1.20 ), reading and writing in the classroom during the break ( OR =1.27), reading in direct sunlight occasionally ( OR =1.20), using only desk lamp for writing at home ( OR =0.71), more than 1 hours of short-distance eye use for a break once ( OR =1.23) were associated with myopia among primary and secondary school students ( P <0.05). Conclusions Outdoor activities and short-distance use of eye among primary and middle school students in minority areas in Yunnan province are suboptimal. Enhancing the related environmental and behavioral factors can effectively mitigate the occurrence and progression of myopia.

Background Indoor air quality directly affects people's health, especially the impact of chemical pollutants in residential indoor air on children and the elderly is more significant. Objective To understand the pollution status of common chemical pollutants in residential indoor air in Shijiazhuang, evaluate the health risks of chemical pollutants to school-age children and the elderly, and provide reference for controlling indoor pollution in residential environment. Methods Using stratified random sampling, a total of 60 households were selected from 2 urban areas and 1 surrounding rural area in Shijiazhuang City, specifically in July 2023 (non-heating season) and December 2023 (heating season), respectively. Relevant data was collected through on-site sampling [including CO, CO₂, PM₁₀, PM_2.5, NO₂, SO₂, O₃, ammonia, formaldehyde, benzene, toluene, xylene, total volatile organic compounds (TVOC), trichloroethylene, and tetrachloroethylene] and survey questionnaires. The pollutant concentrations were evaluated following the Standards for indoor air quality of GB/T 18883-2022, and the inhalation exposure risks of the target population were assessed based on the health risk assessment method. Results In the indoor air of the urban and rural residence in Shijiazhuang City, except for CO, NO₂, SO₂, toluene, and xylene, which did not exceed the standard limits, other pollutants showed varying degrees of exceedance. The non-qualified rates of PM₁₀, PM_2.5, and CO₂ in the urban areas were higher than those in the rural areas (P < 0.05). The seasonal difference analysis showed that the non-qualified rates of PM_2.5, PM₁₀, CO₂, trichloroethylene, and tetrachloroethylene in the urban areas were higher in the heating season than in the non-heating season (P<0.05); the non-qualified rates of ammonia and formaldehyde in the rural areas increased significantly in the non-heating season(P<0.05). The health risk assessment indicated that the maximum hazard quotient (HQ) of tetrachloroethylene for the elderly exceeded 1, while the HQ values for ammonia, formaldehyde, benzene, toluene, xylene, and trichloroethylene remained below 1 for either children or the elderly. For carcinogenic risks, the median carcinogenic risk (CR) of formaldehyde for school-aged children or the elderly fell within the range of 10⁻⁶-10⁻⁴, whereas the median CR values for benzene, trichloroethylene, and tetrachloroethylene were all below 10⁻⁶. Conclusion The primary indoor air pollutants exceeding the national standard limits in residential areas of Shijiazhuang City include CO₂, PM₁₀, TVOC, PM_2.5, formaldehyde, ammonia, trichloroethylene, and tetrachloroethylene. The levels of these pollutants exhibit significant urban-rural and seasonal variations. Special attention should be paid to the non-carcinogenic risk of tetrachloroethylene to the elderly and the carcinogenic risks of formaldehyde to school-age children and the elderly.

Objective To evaluate the therapeutic efficacy for surgical treatments among patients with hepatic cystic echinococcosis in Gansu Province from 2006 to 2023, so as to provide insights into optimization of the diagnosis and treatment strategies against hepatic cystic echinococcosis. Methods The demographic and clinical data of all echinococcosis cases included in central government fiscal transfer payment program for echinococcosis control and undergoing surgical treatments in Gansu Province from 2006 to 2023 were captured. Hepatic cystic echinococcosis patients with complete medical records and follow-up data were included in the study, and patients’ characteristics, including hospital where patients received diagnosis and treatment, methods of case identification, year of surgery, classification of lesions, number of lesions, size of lesions, course of disease, surgical methods, and post-surgical follow-up data. The cure and recurrence of hepatic cystic echinococcosis were evaluated according to the Guidelines for Management of Echinococcosis Patients in the Central Government Fiscal Transfer Payment Program, and the cure and recurrent rates were calculated. Results Data were collected from 1 686 surgical patients with hepatic cystic echinococcosis. According to the inclusion and exclusion criteria, 1 222 hepatic cystic echinococcosis patients undergoing surgical treatments were included during the period from 2006 to 2022, including 1 166 cured patients (95.42%) and 88 patients with postsurgical recurrence (7.20%), and the cure rate of surgical treatments appeared a tendency towards a rise among patients with hepatic cystic echinococcosis from 2008 to 2022 (χ²_trend = 19.39, P < 0.05). The cure rates of hepatic cystic echinococcosis were 100% (177/177), 94.81% (128/135) and 94.62% (861/910) among patients detected through regular physical examinations, screened by the central government fiscal transfer payment program for echinococcosis control, and those who passively sought healthcare services, respectively (χ² = 9.95, P < 0.05). The cure rates of hepatic cystic echinococcosis were 95.96% (1 046/1 090) among patients with a disease course of 2 years and less and 90.90% (120/132) among patients with a disease course of over 2 years (χ² = 6.87, P < 0.05), and there were significant differences in the cure rates among patients with hepatic cystic echinococcosis in terms of number of lesions (χ² = 24.44, P < 0.05) and surgical methods (P < 0.05). The cure rate of hepatic cystic echinococcosis patients was significantly higher following initiation of the central government fiscal transfer payment program for echinococcosis control (96.06%, 1 096/1 141) than before the program (86.42%, 70/81) (χ² = 16.06, P < 0.05), and the cure rate of hepatic cystic echinococcosis patients was significantly higher in designated hospitals (96.48%, 741/768) than in non-designated hospitals (93.37%, 366/392) (χ² = 5.78, P < 0.05). The median follow-up period was 4 (interquartile range, 7) years among 1 222 hepatic cystic echinococcosis patients undergoing surgical treatments. The recurrent rate of hepatic cystic echinococcosis appeared a tendency towards a decline from 2008 to 2022 (χ²_trend = 36.86, P < 0.05), with a reduction from 23.08% (9/39) in 2008 to 1.85% (1/54) in 2021, and the post-surgical recurrence rate of hepatic cystic echinococcosis was lower following initiation of the central government fiscal transfer payment program for echinococcosis control (5.87%, 67 / 1 141) than before the program (25.93%, 21/81) (χ² = 45.51, P < 0.05). In addition, the post-surgical recurrence rate of hepatic cystic echinococcosis was higher in non-designated hospitals (10.46%, 41/392) than in designated hospitals (5.60%, 43/768) (χ² = 9.12, P < 0.05), and there was a significant difference in the post-surgical recurrence rate among patients with hepatic cystic echinococcosis in terms of surgical methods (P < 0.05), with the highest recurrence rate (11.54%) seen among patients undergoing percutaneous fine-needle aspiration of cyst fluids-based surgical procedures (P < 0.05). Conclusion Since the initiation of the central government fiscal transfer payment program for echinococcosis control in Gansu Province in 2006, an increase in the surgical cure rate and a reduction in the recurrence of hepatic cystic echinococcosis had been found among patients with hepatic cystic echinococcosis, indicating a high overall therapeutic efficacy.

Objective:To explore the clinical, imaging, and pathological features of glottic squamous cell carcinoma of the larynx and their relationship with prognosis. Methods:A retrospective analysis was conducted on the clinical, imaging, and pathological data of 130 patients with glottic squamous cell carcinoma of the larynx who were treated at the First People's Hospital of Yinchuan and the General Hospital of Ningxia Medical University from January 2018 to March 2023. Imaging examinations （CT and MRI） were used to evaluate the lesion boundary clarity, density, enhancement nature, and enhancement degree. Postoperative pathological examination was used to determine the pathological nature, immunohistochemistry, etc. Statistical methods such as χ² test, Spearman correlation analysis, multivariate logistic regression analysis, and Kaplan-Meier method were used to analyze the data. Results:Among the 130 patients, 127 were male and 3 were female, with an average age of （61.92±9.595） years. There was a correlation between clinical, imaging, and pathological features. Multivariate analysis showed that heterogeneous MRI density （OR=12.414;P=0.019） and squamous cell carcinoma as a subtype were correlated. The initial symptom of non-hoarseness （HR=6.045;P=0.010） and unclear MRI boundary （HR=12.559; P=0.029） were independent risk factors for poor prognosis in patients with glottic squamous cell carcinoma of the larynx. Conclusion:There is a correlation between the clinical, imaging, and pathological features of patients with glottic squamous cell carcinoma of the larynx, and they can affect prognosis. The initial symptom of non-hoarseness and unclear MRI boundary of the tumor are independent risk factors for poor prognosis.

Objective:To compare the efficacy and safety of red light and daylight photodynamic therapy in the treatment of facial common acne.Methods:From March 2019 to November 2019, 52 patients with facial common acne who received 5-aminolevulinic acid photodynamic therapy in the Department of Dermatology, Chongqing Hospital of Traditional Chinese Medicine were enrolled, including 34 males and 18 females, aged 18-35 years, with an average age of 23.2 years. A 5% concentration of 5-aminolevulinic acid was applied to the entire face, with the right side of the face being exposed to red light for 20 minutes and the left side to daylight for 2 hours. The treatment was administered once a week for a total of 4 sessions. After the treatment, the acne remission, adverse reactions, and patient satisfaction on both sides of the face were compared.Results:Compared with before treatment, the number of inflammatory and non-inflammatory lesions on both sides of the face in the enrolled patients decreased, and there was no significant difference in the clearance rate of skin lesions between the two sides [53.7% (28/52) vs 59.1% (31/52), χ 2=0.89, P>0.05]. The overall effective rate on the red light side was 88.5% (46/52), and 82.7% (43/52) on the daylight side, with no significant difference between the two (χ 2=0.38, P>0.05). In terms of adverse reactions, mild erythema was common, and it was less on the daylight side than on the red light side [34.6% (18/52) vs 19.2% (10/52), χ 2=5.98, P<0.05]. During the treatment period, the pain score on the daylight side decreased compared to the red light side [(7.6±2.3) vs (4.1±1.3), t=13.10, P<0.001]. Overall satisfaction with the daylight side was reported in 49 cases (94.2%), and with the red light side in 37 cases (71.2%), with the daylight side being higher than the red light side, and the difference was statistically significant (χ 2=9.60, P<0.05). Conclusion:Daylight photodynamic therapy is as effective as red light photodynamic therapy for common acne, but it produces fewer adverse reactions and higher patient satisfaction.

Objective:To evaluate the short-term rehabilitation effect of wearable visual training devices based on extended reality (XR) glasses in patients after macular hole surgery.Methods:A self-controlled study was conducted.Eleven patients with monocular low vision after macular hole surgery were recruited at Renmin Hospital of Wuhan University from October 2022 to March 2024.All patients underwent biofeedback training for 3 months using the independently developed visual rehabilitation training glasses LOOKBON T10.The LogMAR best corrected visual acuity (BCVA), retinal sensitivity, effective fixation rate, fixation stability, reading speed, vertical metamorphopsia (MV), horizontal metamorphopsia (MH), and Chinese version of the visual-related quality of life assessment form (CVRQoL-25) were compared before and after training.This study adhered to the Declaration of Helsinki.The study protocol was approved by the Ethics Committee of Renmin Hospital of Wuhan University (No.WDRY2024-K263).Written informed consent was obtained from each subject.Results:After training, the patients' BCVA, retinal sensitivity, effective fixation rate, fixation stability, and reading speed were 0.69±0.19, (21.61±2.75)db, (92.43±4.06)%, (93.09±4.31)%, and (104.82±21.85) characters/minute, respectively, which were significantly improved compared to 0.85±0.28, (17.71±3.17)db, (31.83±19.05)%, (32.35±19.12)%, and (69.64±20.17) characters/minute before training ( t=5.253, -5.987, -11.561, -12.003, -11.682; all at P<0.001).After training, MV and MH were (0.29±0.20)° and (0.21±0.24)°, respectively, which were significantly reduced compared to pre-training (0.44±0.24)° and (0.43±0.41)° ( t=9.238, 4.068; both at P<0.01).After training, the CVRQoL-25 score was 1 193.18±229.43, which was significantly higher than pre-training 947.73±203.86 ( t=-11.687, P<0.001). Conclusions:The application of wearable visual training equipment based on XR glasses can effectively improve the visual function of patients with poor visual function recovery after macular hole surgery, and enhance their quality of life.

Objective:To explore the relationship between the degree of devascularization and clinical outcomes after interventional embolization and sclerotherapy for peripheral arteriovenous malformations.Method:A retrospective analysis was conducted on the data of 37 patients with peripheral arteriovenous malformations admitted at Department of Cardiovascular Surgery, China-Japan Friendship Hospital from July 2021 to June 2023. All patients received the treatment of "nidus" and/or outflow veins embolization combined with sclerotherapy injection. Two experienced physicians evaluated the degree of devascularization before and after treatment, and conducted a correlation study with clinical outcomes after follow-up.Result:All 37 patients were symptomatic. Swelling and pain accounted for 75.7% of all the cases. Twenty-six patients received only one procedure, 3 patients received re-interventional treatments. The average follow-up time was（13.3±5.0）months. Clinical symptoms were completely relieved in 14 patients, and partial relief in 22 patients. The overall effective rate was 97%. There were 6 patients with degree of de vascularization<50% during procedure, 16 patients with degree of 50%-75%, and 5 patients with degree of 75%-90%, 10 cases with degree over 90%. Patients with devascularization degrees less than 60% can not achieve clinical symptom relief.Conclusions:There is a positive correlation between the degree of devascularization and clinical outcomes in the interventional embolization and sclerotherapy of peripheral arteriovenous malformations, and 60% of the degree of devascularization can serve as the "threshold" for effectiveness of treatment.

Antipsychotics, lithium preparations can cause a variety of renal side effects, most of which occur insidiously. The paper reports a 46-year-old female patient developing fatigue and soft paresis after taking lithium carbonate for 17 years. Laboratory tests showed hypokalemia, distal renal tubular acidosis (dRTA), and renal calculus. After discontinuation of lithium carbonate, partial remission of hypokalemia and dRTA were observed. Combined with literature review, in addition to dRTA, the renal side effects of lithium preparations also include acute toxic kidney injury, nephrogenic diabetes insipidus and various glomerulopathy.

It is estimated that approximately seven million people worldwide are affected by inflammatory bowel disease(IBD),causing a huge burden on healthcare systems and society.In the occurrence,progression,and treatment of IBD,the intestinal microbiota and its key metabolic product,bile acids,play a crucial role.The intestinal microbiota not only participates in the biotransformation of bile acids,enriching the diversity of bile acids,but also regulates their synthesis and transport through the farnesoid X receptor(FXR).Meanwhile,bile acids contribute to regulating the structure and function of the intestinal microbiota by supporting microbial diversity,exerting direct toxicity,participating in indirect antimicrobial pathways,and influencing microbial metabolic capabilities.Furthermore,under normal physiological conditions,intestinal microbiota-derived bile acids facilitate the repair process of the intestinal epithelial barrier.They also promote the balance of the immune system by modulating the functions of various immune cells including helper T(Th)cells 17,regulatory T(Treg)cells,CD8+T cells and natural killer T(NKT)cells,thereby slowing down the development of IBD.This article focuses on exploring the role of intestinal microbiota and bile acids in the onset and progression of IBD,and investigating new effective treatment strategies by targeting intestinal microbiota and bile acids,such as bile acid receptor modulators,probiotics,prebiotics,fecal microbiota transplantation(FMT),and phage therapy.

Objective:To explore the clinical and genetic characteristics of five children with epilepsies due to variants of SCN8A gene. Methods:Clinical data of five children (four males and one female) admitted to Linyi People′s Hospital due to hereditary epilepsies between August 2015 and August 2022 were collected. Whole exome sequencing was carried out for these children, and candidate variants were verified by Sanger sequencing.Results:All of the five children were found to harbor variants of the SCN8A gene. Case 1, who had benign familial infantile epilepsy, inherited a known pathogenic c. 4840A>G variant from his father with similar symptoms. Cases 2 to 4 had presented with intermediate epilepsy. Among these, case 2 has harbored a de novo c. 3967G>A variant which was rated as pathogenic (PS1+ PS2+ PM1+ PM2_Supporting+ PP3) based on the guidelines from the American College of Medical Genetics and Genomics. Cases 3 and 4 were found to respectively harbor a de novo c. 415A>T and a c. 4697C>T variant, which were both rated as likely pathogenic (PS2+ PM1+ PM2_Supporting+ PP3). Case 5, who had early-onset infantile epileptic encephalopathy transformed into Lennox Gastaut-like syndrome, has harbored a de novo c. 5615G>A variant, which was known to be pathogenic. The children had their age of onset ranging from 2 to 14 months, and all had focal seizures and generalized tonic clonic seizures. Four children (cases 1, 2, 3 and 5) had cluster seizures, four (cases 1 to 4) had become seizure-free after single or dual treatment and showed normal growth and development, whilst case 5 was drug-resistant and showed severe developmental retardation. Conclusion:The five children had new features such as cluster seizures, occasional benign seizures in adulthood, and intermediate epilepsy which are prone to relapse after discontinuation of medication, which may be attributed to the pathogenic variants of the SCN8A gene.
