Objective: To investigate the recreational use status of electronic products among high school students in Shanxi Province and the influencing factors for excessive use, so as to provide insights into the promotion of rational use of electronic products among high school students. Methods: The high school students from 117 schools in Shanxi Province were selected using the stratified random sampling method, and basic information, lifestyle behaviors and recreational use of electronic products were collected using questionnaire surveys. The prevalence of excessive recreational use of electronic products was analyzed, and the factors affecting excessive recreational use of electronic products among high school students were analyzed using a multivariable logistic regression model. Results: A total of 13 804 valid questionnaires were recoverd, with an effective rate of 98.32%. There were 6 634 males (48.06%) and 7 170 females (51.94%), with a median age of 17.00 (interquartile range, 1.00) years. There were 7 024 students in Grade One (50.88%) and 6 780 students in Grade Two (49.12%). The prevalence of recreational use of electronic products was 14.18% (1 958 cases). Multivariable logistic regression analysis showed that males (OR=1.461, 95%CI: 1.325-1.611), students in Grade Two (OR=1.720, 95%CI: 1.559-1.897), students whose parents had below high school education (OR=1.391, 95%CI: 1.156-1.674), students without parental support (OR=1.281, 95%CI: 1.078-1.523), students not living on campus (OR=1.142, 95%CI: 1.026-1.271), students without myopia (OR=1.121, 95%CI: 1.008-1.248), and students with sufficient sleep (OR=1.162, 95%CI: 1.054-1.281) had a higher risk of excessive recreational use of electronic products. Conclusion The prevalence of excessive recreational use of electronic products among high school students in Shanxi Province was relatively high, which was related to gender, grade, parental education, parental attitudes, boarding status, myopia and sleep quality.

Objective:To summarize the genetic and phenotypic features of MORC family CW-type zinc finger 2 (MORC2) gene-related neuropathy in Chinese patients. Methods:The clinical and whole exome sequencing data of MORC2 gene-related neuropathy families with a definitive genetic diagnosis were collected from the Third Xiangya Hospital of Central South University between 2010 and 2023. Literature involving Chinese families with MORC2 gene-related neuropathy was extensively reviewed to provide a comprehensive summary of the genetic and phenotypic spectrum of the disease. Results:A total of 10 families with MORC2 gene-related neuropathy were identified and analyzed. Six different heterozygous pathogenic variants in the MORC2 gene were observed among these families, including the novel variant c.1330G>C (p.G444R) that had not been previously reported. Six families presented as axonal Charcot-Marie-Tooth disease caused by variants in the MORC2 gene (CMT2Z) phenotype with childhood or adult onset, and carried variants c.754C>T (p.R252W), c.1199A>G (p.Q400R), c.1330G>C (p.G444R), or c.1396G>A (p. D466N); 3 families manifested as severe spinal muscular atrophy (SMA)-like phenotype with infantile onset, all carried c.260C>T (p.S87L); 1 family carried c.1181A>G (p.Y394C), presented as DIGFAN syndrome phenotype with infantile onset combined with mental and motor retardation. Systematic review showed 8 Chinese families carried pathogenic variants of the MORC2 gene, among which 5 families were associated with the CMT2Z phenotype, carrying c.754C>T (p.R252W), c.1079A>G (p.E360G), c.1220G>A (p.C407Y), or c.1397A>G (p.D466G); 1 family was associated with SMA-like phenotype, carrying c.260C>T (p.S87L); and 2 families were associated with DIGFAN syndrome, carrying c.79G>A (p.E27K) and c.292G>A (p.G98R). Conclusions:A novel pathogenic variant c.1330G>C (p.G444R) of the MORC2 gene associated with the CMT2 phenotype is reported. Eleven pathogenic variants of the MORC2 gene have been reported in the Chinese patients to date, and c.754C>T(p.R252W) may be the most common. Patients with MORC2 gene-related neuropathy carrying different variants present with significant clinical heterogeneity, manifesting as CMT2Z, early-onset severe SMA-like myasthenia, or DIGFAN syndrome.

ObjectiveTo explore the mechanism of Naoxintong capsules' intervention in cerebral ischemia-reperfusion by building a mouse cerebral ischemia-reperfusion model based on short-chain fatty acids. MethodC57BL/6J male mice were randomly divided into the sham group， model group， Naoxintong group （158.9 mg∙kg^-1）， and Ginaton group （12.1 mg∙kg^-1） according to the random number table method. The model of cerebral ischemia-reperfusion （MCAO/R） was prepared via the filament occlusion method. The effect of Naoxintong capsules on brain injury in MCAO/R mice was evaluated by the neuroethological score， cerebral infarction area determination， Nissl staining， and immunofluorescence staining. Hematoxylin-eosin （HE） staining and Western blot were employed to evaluate the effect of Naoxintong capsules on the intestinal barrier in MCAO/R mice. The content of short-chain fatty acids in mouse feces was detected by LC-MS/MS. ResultCompared to the sham group， the model group exhibited significant increases in the cerebral infarction area， neuroethological score， and cell apoptosis rate （P<0.01）， with a notable decrease in the number of Nissl bodies （P<0.01）. The protein expression levels of Claudin-1 and Occludin were significantly reduced （P<0.05）. Compared with the model group， the intervention of Naoxintong capsules significantly decreased the cerebral infarction area （P<0.05） and improved the neuroethological score （P<0.01） and cell apoptosis rate （P<0.01）， with the number of Nissl bodies （P<0.01） and expression levels of Claudin-1 and Occludin proteins （P<0.01） increased. LC-MS/MS results showed that compared to the sham group， the model group featured a significantly reduced content of acetic acid， propionic acid， and butyric acid in feces （P<0.01）， while valeric acid， isovaleric acid， and isobutyric acid levels were increased （P<0.01）. The intervention of Naoxintong capsules notably lowered the content of valeric acid， isovaleric acid， and isobutyric acid （P<0.01）. ConclusionNaoxintong capsules can improve brain and intestinal barrier damage and play a protective role in cerebral ischemia-reperfusion by regulating the content of short-chain fatty acids.

ObjectiveBased on the integrated strategy of "empirical prescriptions in ancient books-medical cases by prestigious doctors-computational analysis"， this study aims to explore and analyze the prescriptions and medical cases for treating tremors in traditional Chinese medicine （TCM）， predict their efficacy， and obtain the core prescriptions for treating tremors in TCM， providing references for clinical application and new drug development. MethodThe Chinese Medicine Prescription Database and the China National Knowledge Infrastructure （CNKI） were searched for relevant prescriptions and medical cases for treating tremors in TCM to establish a database of prescriptions for tremors. The Traditional Chinese Medicine Inheritance Computer System （V3.0） was used to analyze and explore the medication rules including drug frequency， properties， flavor， meridian tropism， and pharmacological effects， as well as core drugs and formula associations. A multi-target drug efficacy prediction platform based on network robustness was used to evaluate the predicted efficacy of the core prescriptions obtained. Based on the integration of ancient prescriptions， prestigious doctors' medical cases， and network analysis results， the priority level of the developed prescriptions was determined through comprehensive evaluation. ResultA total of 81 ancient prescriptions were screened， involving 246 drugs， and 171 prescriptions were screened from prestigious doctors' medical cases， involving 278 drugs. The frequently used TCM drugs were mostly warm in nature and sweet in flavor， mainly acting on the liver， spleen， and kidney meridians. In terms of efficacy， they were mainly effective in tonifying deficiency， soothing liver and extinguishing wind， activating blood and resolving blood stasis， clearing heat， and resolving exterior. Through association rules and K-means clustering， the core prescriptions were composed of high-frequency drugs such as Glycyrrhizae Radix et Rhizoma， Ginseng Radix et Rhizoma， Astragali Radix， Atractylodis Macrocephalae Rhizoma， Angelicae Sinensis Radix， Poria， Gastrodiae Rhizoma， and Uncariae Ramulus Cum Uncis. Drug combinations mainly focused on tonifying Qi and nourishing blood， with the additional functions of calming wind and dredging collaterals. Clustering analysis of core prescriptions from ancient prescriptions and prestigious doctors' medical cases， as well as multi-target drug efficacy prediction， showed that Combination 1 had the highest disturbance score on the disease network. Furthermore， comparative analysis revealed consistent results with both the analysis of ancient prescriptions and prestigious doctors' medical cases， indicating its optimal development potential based on theoretical inheritance and empirical practice. In comparison， Combinations 3， 2， and 4 were less utilized in contemporary clinical practice， with lower rankings in network disturbance scores， suggesting that their development value still warranted further exploration. ConclusionTCM clinical treatment of tremors emphasizes the regulation of the liver， spleen， and kidney. In line of syndrome differentiation， drugs potent in soothing liver， extinguishing wind， activating blood， and resolving blood stasis are added based on deficiency-tonifying drugs. The core prescriptions based on Glycyrrhizae Radix et Rhizoma， Angelicae Sinensis Radix， Paeoniae Radix Alba， Astragali Radix， Poria， and Atractylodis Macrocephalae Rhizoma （combination 1） have the highest potential development value. The integrated strategy "empirical prescriptions in ancient books-medical cases by prestigious doctors-computational analysis" can be used for the screening of candidate prescriptions for new TCM drugs.

Objective:To investigate the prevalence of cataracts, the surgical coverage, and postoperative visual acuity of adults in Ningxia.Methods:A cross-sectional study using multistage cluster random sampling was conducted.Ten survey sites in Ningxia were selected and the population aged 18 years and over was surveyed with questionnaire, height and weight measurements, visual acuity, intraocular pressure, fundus photography and slit-lamp examinations.Cataract prevalence and its influencing factors were analyzed.Cataract prevalence, surgical coverage and presenting visual acuity (PVA) and best corrected visual acuity (BCVA) after surgery were investigated in different age groups of the examined population.The study adhered to the Declaration of Helsinki and was approved by the Ethics Committee of the People's Hospital of Ningxia Hui Autonomous Region (No.[2023]-LL-010).Participants signed informed consent prior to the examination.Results:A total of 6 145 people should be examined, and 5 721 people were actually examined, with an examination rate of 93.10%.The study population consisted of 2 558 males, accounting for 44.71%, and 3 163 females, accounting for 55.28%, with ages ranging from 18 to 93 years old and an average age of (64.27±13.48) years.Among them, 1 180 patients diagnosed with cataract, with a cataract prevalence of 20.62%.The prevalence of cataract increased with age and decreased with education level, showing statistically significant differences ( χ2=1 091.32, 581.92; both at P<0.01).The prevalence of cataract was significantly higher among people with hypertension, diabetes mellitus, hyperlipidemia, and coronary heart disease than those without these diseases ( χ2=274.65, 118.15, 78.05, 182.71; all at P<0.01).Cataract surgery was performed in 245 cases in the cataract patient population, with a surgical coverage rate of 20.76%.Of the 245 cases, 229 cases were implanted with IOLs, with an implantation rate of 93.40%.The social burden rate of cataract blindness was 2.29%, and increased with age.Of the 339 eyes that underwent cataract surgery, 241 had a PVA≥0.3, accounting for 71.09%, and 272 had a BCVA≥0.3, accounting for 80.24%. Conclusions:In Ningxia, cataracts are still the main cause of vision impairment and blindness in the elderly, and the social burden rate of cataract blindness is high.Moreover, the coverage rate of cataract surgery is low, so both the coverage and quality of surgery need improvement.
