ObjectiveTo analyze the potential risk of infection sources during the consolidation phase of schistosomiasis elimination in Lushan County (a mountainous region) of Sichuan Province, and to provide prevention and control strategies for the consolidation of schistosomiasis elimination achievements in mountainous areas. MethodsIn 2024, one to two villages with historically severe epidemics were selected in the heavily endemic townships of Lushan County as monitoring sites to carry out monitoring for wild animal feces, domestic animals, wild rats, free-roaming dogs, local residents, and mobile populations. Follow-up monitoring for previously infected individuals was carried out in Caoping Village of Siyan Town. Statistical analyses were performed to assess the risks associated with infection sources. ResultsA total of 115 fecal samples from 13 species of wildlife were incubated, with all negative. Blood tests were conducted on 492 cattle, 34 sheep, and 261 dogs, with all negative. A total of 2 520 rodent traps were set, capturing 67 wild rats with a capture rate of 2.66%, and no positive wild rats were found upon dissection. The activity track of 25 loose dogs was 2 212 meters at the farthest, 236 meters at the nearest, and 744 meters on average. a total of 68 wild droppings (all dog feces) were picked up along the way, with all negative. Blood tests were performed on 3 540 local population, yielding 39 blood-positive cases with a blood positive rate of 1.1%. Fecal examinations were conducted on 193 individuals, with all negative. A total of 315 blood tests were performed on the mobile population, identifying 1 positive case with a blood-positive rate of 0.32%. One person received a fecal examination, with zero positive. A follow-up survey of 505 previously infected individuals revealed 5 blood-positive cases, with a positive rate of 0.99%. Fecal examinations were conducted on 15 individuals, with all negative. ConclusionIn this investigation, no local or imported sources of schistosomiasis transmission were found. However, there was a wide variety and a large number of potential sources of infection in the local area. It is necessary to actively explore regional monitoring models for schistosomiasis elimination flexibly adjust prevention and control strategies according to local conditions, achieve precise prevention and control, and consolidate the achievements of elimination.

Background: The surgical neck of the humerus is located approximately 2–3 cm distal to the anatomical neck (collum anatomicum) at the junction of the greater and lesser tubercles and the humeral shaft. Owing to the transition between cortical and cancellous bones, this region is biomechanically vulnerable and prone to fractures, particularly in older adults. Fractures of the surgical neck of the humerus are classified under the International Classification of Diseases, 10th Revision (ICD-10), with diagnostic codes S42.21.3, S42.22, and S42.23. National statistics indicate that 210,763 new trauma cases were reported in Mongolia in 2023, representing an 11.6% increase compared to the previous year, of which 11,452 cases (5.4%) involved shoulder and humeral injuries. Aim: This study aimed to compare the clinical effects of traditional Mongolian bone-setting therapy and surgical treatment on pain intensity, shoulder function, range of motion, and activities of daily living in patients with surgical neck of the humerus fractures. Materials and Methods: Based on the Department of Traditional Therapies of the Mongolian National University of Medical Sciences (MNUMS) and the Department of Orthopedic Trauma of the Inner Mongolia International Hospital, Inner Mongolia Autonomous Region, China, a total of 60 patients diagnosed with surgical neck fractures of the humerus were enrolled in this study between January 2024 and December 2025. The patients were randomly assigned into two groups: a Mongolian traditional bone-setting therapy group (n=30) and a surgical treatment group (n=30). Assessments were conducted before treatment and at 1 month and 3 months after treatment. Shoulder joint range of motion, activities of daily living, and muscle strength were evaluated using the Constant–Murley score, while pain intensity was assessed using the Visual Analog Scale (VAS). The collected data were systematically analyzed, and the therapeutic outcomes of the two treatment modalities were comprehensively compared and summarized. Result: The baseline demographic and clinical characteristics were comparable between the groups. In the traditional bone-setting group, VAS scores decreased significantly, whereas Constant–Murley scores improved markedly at both follow-up points. The overall outcomes in the traditional bone-setting group were significantly better than those in the surgical group (P<0.05). Conclusion Traditional Mongolian bone-setting therapy offers rapid pain relief, superior long-term functional recovery, and fewer complications, making it a valuable treatment option, particularly for elderly patients and those unsuitable for surgery.

Objective: To explore the treatment plan for severe papillary defects in the aesthetic zone caused by severe periodontitis, providing a reference for clinical practice. Methods : A patient with severe periodontitis leading to severe papillary defects in the upper anterior teeth from 12 to 23 was treated using interdental tunnel technique combined with personalized connective tissue grafting for periodontal plastic surgery, and stable soft tissue augmentation was achieved. Resin restoration was conducted to modify the crown shape of the aesthetic zone teeth, reconstruct white aesthetics, guide the shaping of the gingival papillae, reduce “black triangles,” and enhance the patient’s confidence in smiling. Results : The patient’s periodontal condition and the regeneration of soft tissues in the aesthetic zone were good, and the smile aesthetics were restored. After a 3-year follow-up, the gingival morphology, color, and texture were good, and the effect was stable. The literature review indicates that for papillary defects in the aesthetic zone, analysis should be conducted based on the following aspects: whether a defect is present in periodontal hard and soft tissues, crown shape, and the distance from the most apical part of the crown contact area to the top of the alveolar crest. Based on the analysis of aesthetic defects and surgical indications, a personalized treatment plan should be designed. Conclusion For patients with obvious papillary defects in the aesthetic zone due to the reduction of periodontal support tissues caused by severe periodontitis, factors such as periodontal hard and soft tissue defects, crown shape, and the distance from the most apical part of the crown contact area to the top of the alveolar crest should be fully considered, and a personalized treatment plan should be formulated after multidisciplinary joint consultation.

Diabetes mellitus （DM） is a metabolic disease caused by absolute or relative insulin deficiency and reduced insulin sensitivity in peripheral cells， posing a serious threat to global health. Chronic complications arising in the later stages of DM can lead to the decline or even loss of function in multiple organs， including the eyes， heart， liver， kidneys， nerves， and feet， making them the primary cause of mortality in DM patients. Although modern medicine has made some progress in the treatment of these complications， challenges such as high costs and adverse drug reactions remain. Thus， identifying highly effective drugs with minimal adverse effects has become a top priority. Astragalus membranaceus is a shining gem in the treasure trove of Chinese medicine. Numerous studies have shown that its primary active component， astragaloside Ⅳ， possesses various biological activities， including anti-inflammatory， antioxidant， and antiviral effects， as well as benefits for cardiac and cerebral function， nerve conduction， and myocardial protection. Meanwhile， the phosphatidylinositol 3-kinase/protein kinase B （PI3K/Akt） signaling pathway plays a crucial role in regulating oxidative stress， inflammatory responses， apoptosis， and autophagy. Extensive research has highlighted the significant role of this pathway in various DM complications， leading to widespread studies on its interaction with astragaloside Ⅳ. This review summarizes research findings on how astragaloside Ⅳ alleviates pancreatic cytotoxicity in DM patients by modulating the PI3K/Akt pathway. Additionally， it highlights its protective effects on basic cardiac function， inhibition of retinal cell damage， improvement of cerebral nerve dysfunction， reduction of chronic kidney and liver damage， and mitigation of neurovascular toxicity in the lower limbs. These insights provide a valuable reference for the clinical application of A. membranaceus and its active monomer， astragaloside Ⅳ， in the treatment of DM and its complications.

Objective:To identify core genes with co-expression trends in the suprachiasmatic nucleus (SCN) and lateral habenula (LHb) through miRNA sequencing, and to explore the molecular mechanisms underlying the onset and progress of sleep disturbances in depression.Methods:A rat model of depression with sleep disturbances was established. Behavioral assessments were conducted using the pentobarbital-induced sleep test, sucrose water consumption test, and open field test. Differentially expressed genes (DEGs) in the SCN and LHb of model rats were analyzed using biological replicates with the limma package and DESeq2 software. Gene ontology (GO), KEGG, Reactome pathway-gene set enrichment analysis (GSEA) were performed on the DEGs.Co-expression networks and protein-protein interaction (PPI) networks were constructed using R and Cytoscape software for further screening of genes with potential regulatory roles.Results:After modeling, the sleep latency in the model group ((679.88±350.05) s) was longer than that in the normal group ((316.25±87.35) s) ( t=-2.851, P=0.022), while the sleep duration in the model group ((33.13±8.41) min) was shorter than that in the normal group ((69.72±25.11) min) ( t=3.907, P=0.004). Additionally, the model group exhibited lower sucrose water consumption, horizontal movement counts, and vertical movement counts compared to the normal group (all P<0.05). Differential expression gene analysis showed, in the SCN, 379 genes were upregulated and 132 genes were downregulated, with the top five most significantly differentially expressed genes being Sec61g, Cox6b1, Ephx2, Thrsp, and Pak2. In the LHb, 1 657 genes were upregulated and 1 737 were downregulated, with the top five most significantly differentially expressed genes being Mrpl32, Mrpl20, Mrpl27, Celsr2, and Uba52. Biological pathways enriched in the SCN were mainly associated with the positive regulation of responses to external and biological stimuli. In contrast, pathways enriched in the LHb were related to neurotransmitter level regulation, developmental growth, neurotransmitter transport, and processes such as learning and memory. Co-expression network analysis identified 864 interactions involving 100 nodes in the SCN and 524 interactions involving 99 nodes in the LHb. Conclusion:The biological functions and signaling pathways of the suprachiasmatic nucleus and lateral habenula are different in the occurrence and development of depression with sleep disturbance, and the significantly differentially expressed genes may play an important role.

Objective:To analyze the differences between subjective refraction and autorefraction in myopic children and adolescents under different ciliary muscle functional states.Methods:A cohort study was conducted.A total of 98 myopic children and adolescents (196 eyes) aged 7-15 years who visited the Shanghai Eye Disease Prevention and Treatment Center from November 2023 to February 2024 were included by random sampling.All participants underwent cycloplegia with 1.0% cyclopentolate and completed both subjective refraction and autorefraction before cycloplegia, after cycloplegia and after recovery from cycloplegia.The spherical equivalent (SE) differences and differences in SE(ΔSE) between different conditions were compared.Proportion of ΔSE, differences in spherical power (ΔS), and differences in cylindrical power (ΔC) of objective and subjective refraction between different conditions within the clinically acceptable error range (-0.25 to 0.25 D) was calculated and compared.This study adhered to the Declaration of Helsinki.The study protocol was approved by the Ethics Committee of Shanghai Eye Diseases Prevention & Treatment Center (No.2021SQ021).Written informed consent was obtained from guardian of each subject before any medical examination.Results:The SE values obtained from autorefraction before cycloplegia, after cycloplegia, and after recovery from cycloplegia were -2.44(-3.47, -1.63), -2.13(-3.25, -1.50), and -2.38(-3.50, -1.66)D, respectively, with a statistically significant overall difference ( χ2=148.36, P<0.001) and statistically significant differences in pairwise comparisons at different time points (all P<0.001); for subjective refraction, the SE values were -2.25(-3.50, -1.50), -2.19(-3.47, -1.45), and -2.28(-3.50, -1.50)D, respectively, with a statistically significant overall difference ( χ2=43.48, P<0.001) and statistically significant differences in pairwise comparisons at different time points (all P<0.001).Subjective refraction ΔSE between before and after cycloplegia, after cycloplegia and after recovery from cycloplegia were significantly smaller than those of autorefraction ( t=2.84, 1.82; both P<0.001).There was no significant difference in ΔSE between subjective refraction and autorefraction between before cycloplegia and after recovery from cycloplegia ( t=-0.43, P=0.070).The proportions of subjective refraction ΔSE within the acceptable error range between before and after cycloplegia, before cycloplegia and after recovery from cycloplegia, and after cycloplegia and after recovery from cycloplegia were significantly higher than those of autorefraction ( χ2=28.32, 11.82, 25.55; all P<0.001).The proportion of subjective refraction ΔS and ΔC both within the acceptable error range between before cycloplegia and after recovery from cycloplegia was 81.63%(160/196) and 79.59%(156/196) between after cycloplegia and after recovery from cycloplegia. Conclusions:Subjective refraction is less affected by different ciliary muscle functional states.The differences in subjective refraction results under different ciliary muscle functional states are mostly within the acceptable error range.The subjective refraction results before or after cycloplegia can be used to better predict the subjective refraction results after recovery from cycloplegia.

Objective To examine the level of sperm flagellar tubulin glycosylation(Gly-Tubulin)in asthenospermia patients(AP)and discuss its significance.Methods According to the principle of inclusion and exclusion criteria,108 patients treated in the Department of Andrology in Xinjiang Uygur Autonomous Region Maternal and Child Health Hospital from June 2021 to May 2022 were rolled in this study.According to the results of semen examine,they were divided into group AP(n=74),and normal control(NC)group(n=34).Colleced the clinical date of both group,such as the age,the sterility period.The levels of sex hormones were detected by chemiluminescence method.The glycosylated Tubulin levels of the sperm were detected by Western blot and immunofluorescence was used for localization analysis,and the relationship between the Gly-Tubulin of sperm flagellar and asthenospermia was analyzed by Multivariate Logistic regression analysis.Results Compared to NC group,the sterility period of group AP was prolong(3.98±0.30 vs 0.78±0.08),the percent of forward sperm motility was decreased(18.55±0.97 vs 46.24±1.89)and the expression level of Gly-Tubulin in the sperm flagellar was decreased(0.64±0.11 vs 1.00±0.00),the differences with statistical significance(t=62.038,χ2=14.394,3.148,all P＜0.05).There were no significant differences in follicle-stimulating hormone(FSH),luteinizing hormone(LH),prolactin(PRL),estradiol(E2),testosterone,semen volume,sperm concentration and total sperm between the two groups(t/χ2=0.043～1.503,all P>0.05).Multivariate Logistic regression analysis showed that the percent of forward sperm motility and the sperm flagellar Gly-Tubulin expression level were independent risk factors for male asthenospermia(Wald χ2=4.406,7.492,P<0.05).Conclusion Abnormal level of Gly Tubulin in sperm flagella may be closely related to the occurrence and development of asthenospermia.
