Objective: To analyze the implementation status and challenges of sex education in special education schools, so as to provide a scientific basis for formulating effective promotion strategies. Methods: From November 2023 to January 2024, a census survey was conducted among 120 in service teachers from 7 special education schools in Luzhou. The questionnaire covered the current status of sex education in schools, teachers attitudes and knowledge toward sex education, and their coping methods for students inappropriate sexual behaviors. Results: About 77.5% of teachers reported having provided sex education to students, but 93.2% indicated a lack of specialized sex education textbooks for special children, 90.4% reported no full time teachers for sex education, and the methods of sex education were relatively limited (50.0% mainly based on lecture method). Nearly 95.8% of teachers held a positive attitude toward sex education, with 98.3% supporting its implementation. Only 26.7% of teachers demonstrated a good grasp of sex education knowledge, with the best understood topic being "recognition and protection of private parts" (21.6%). When dealing with students inappropriate sexual behaviors, the active response rate of teachers was 23.9%, with the highest active response rate observed for "intentionally hugging or kissing the opposite sex" (39.7%). Conclusions The special education schools in Luzhou lack comprehensive sex education curricula, teaching materials and full time teachers, sufficient knowledge among teachers, and adequate proactive responses to students inappropriate sexual behaviors. Greater emphasis should be placed on sex education for special children, including the training of dedicated teachers, to provide comprehensive and high quality sex education services for special children.

Objective:To evaluate the efficacy of calaglitzin combined with Degu insulin Liraglutide and pioglitazone metformin in the treatment of obese type 2 diabetes mellitus (T2DM) .Methods:Ninety-nine obese T2DM patients admitted to our hospital from Apr. 2021 to Jun. 2023 were divided into 2 groups according to different treatment methods. The control group ( n=52) were treated with Delgu insulin liraglutide and pioglitazone metformin; the observation group ( n=47) were treated with cagaglizin on the basis of the control group, and both groups were treated for 8 weeks. The therapeutic effect of the two groups was compared. Results:The effective rate of observation group was 95.74% (45/47), higher than that of control group 82.69% (43/52) ( P<0.05). After eight weeks of treatment, the levels of FPG (7.96±0.74) mmol/L, 2hPBG (8.36±1.02) mmol/L and BMI (24.63±1.51) kg/m 2 in the observation group were higher than those in the control group ( P<0.05). After 8 weeks of treatment, HOMA-IR (2.41±0.56) of observation group was lower than that of control group (2.84±0.61), GIR (5.63±0.97) mg·kg -1·min -1 was higher than that of the control group (5.17±0.95) mg·kg -1·min -1 ( P<0.05). After eight weeks of treatment, the levels of TG (4.22±0.43) mmol/L, TC (2.15±0.21) mmol/L and ApoB (1.18±0.14) mmol/L in the observation group were higher than those in the control group (2.49±0.26) mmol/L, (4.69±0.47) mmol/L and (1.45±0.19) mmo l/L ( P<0.05). The incidence of adverse reactions in the observation group was 8.51% (4/47), lower than that in the control group (5.77% (3/52) ( P>0.05) . Conclusion:Taking calaglitzin in combination with Delgu insulin liraglutide and pioglitazone metformin can significantly reduce insulin resistance, increase the sensitivity of peripheral tissues to insulin, reduce blood glucose level and BMI level, and the drug safety is reasonable.

Systemic lupus erythematosus (SLE) is an acute or chronic autoimmune disease characterized by the presence of pathogenic autoantibodies and immune complexes, and multiorgan damage. It is a highly heterogeneous disease and commonly developed in women of childbearing age. The cause of systemic immunopathological injury in SLE is due to the production of autoantibodies by overactivated autoreactive B cells. The treatment of SLE by targeting B cells is very effective, suggesting the critical role of B cells in the development and progression of SLE. However, the current B cell depletion therapies all target the total B cell population, which are not capable of clearing specifically autoreactive B cells since the specific marker molecules and the mechanisms associated with the development of SLE remain unclear. With the development of science and technology, high-throughput sequencing technology provides new ideas for the study of B cell abnormalities in SLE. This review focuses on the progress in high-throughput sequencing to reveal new abnormalities in B cell receptors, new B cell subsets and B cell-related novel therapeutic targets, hoping to provide reference for better understanding the pathogenesis and exploring therapeutic strategies.

In recent years,with the gradual maturity of achievable remote collection of digital health technology,more and more clinical research have applied this technology to improve the quality of data collection and reduce the burden on subjects.However,its technological characteristics of detachment from the diagnostic and treatment environment and real-time transmission of sensitive information also pose corresponding risks to the protection of subjects'rights and interests and data standardization management,among which personal information protection and data control permissions are more prominent issues.Based on risk analysis and regulatory review,this paper explored the responsibilities of multiple parties,including the sponsors,researchers,clinical trial institutions,and ethics committee,as well as proposed five elements of special concern for ethical review,with a view to providing a reference for promoting the standardized development of digital health technology in clinical research.

Objective:To explore the mechanism of zoledronic acid (ZOL) affects osteogenic differentiation and bone formation through the regulation of sirtuin 3 (SIRT3) / P53 expression.Methods:Bone marrow mesenchymal stem cells (BMSCs) were induced to differentiate into osteogenic cells, the expression of SIRT3 in the cells was detected, and the targeting regulation relationship between SIRT3 and P53 was analyzed. The intracellular expressions of SIRT3 and P53 were intervened and ZOL was used to treat the cells. MTT method, Western blot method and kit were used to detect cell viability, osteogenesis-related genes Osteoprotegerin (OPG), runt-related transcription factor 2 (Runx2) expression, alkaline phosphatase (ALP) activity and alizarin red S (ARS) staining, respectively. Ovariectomy (OVX) was used to construct a rat model and explore the effect of ZOL on the progression of osteoporosis (OP) in vivo.Results:ZOL promoted osteogenic differentiation of BMSCs. The expression of SIRT3 was down-regulated in the serum of OP patients (0.78±0.23) compared with that of healthy subjects (1.00±0.26 vs. 0.78±0.23. t=3.85, P<0.001). During the osteogenic differentiation of BMSCs, the expression level of SIRT3 gradually increased with the prolonged induction of osteogenesis. Compared with the p53 protein expression and BMSCs activity in the control group, SIRT3 knockout could increase the expression level of p53 protein (0.59±0.05 vs. 1.01±0.11. t=6.02, P=0.004) but inhibited the activity of BMSCs (100.00±8.41 vs. 51.26±5.59. t=8.36, P=0.001). After ZOL treatment, the inhibitory effect of SIRT3 on cell viability (49.61±5.11 vs. 87.61±7.31. t=7.38, P=0.002) and osteogenesis was relieved, and the level of P53 was inhibited (1.10±0.10 vs. 0.69±0.04. t=6.59, P=0.003). P53 overexpression partially offseted the effects of ZOL on cell viability (84.61±6.52 vs. 66.54±5.47. t=3.68, P=0.021) and osteogenesis. Compared with the sham surgery group, the OVX group showed inhibition of osteogenesis in rats, and ZOL treatment significantly improved osteogenic inhibition. ZOL treatment increased the expression level of SIRT3 protein in bone tissue of OVX rats, but inhibited the expression level of P53. Conclusion:ZOL promoted osteogenic differentiation and bone formation of BMSCs by promoting the ubiquitination and degradation of P53 by SIRT3.

To explore the differentially expressed genes (DEGs) related to biosynthesis of active ingredients in wolfberry fruits of different varieties of Lycium barbarum L. and reveal the molecular mechanism of the differences of active ingredients, we utilized Illumina NovaSeq 6000 high-throughput sequencing technology to conduct transcriptome sequencing on the fruits of 'Ningqi No.1' and 'Ningqi No.7' during the green fruit stage, color turning stage and maturity stage. Subsequently, we compared the profiles of related gene expression in the fruits of the two varieties at different development stages. The results showed that a total of 811 818 178 clean reads were obtained, resulting in 121.76 Gb of valid data. There were 2 827, 2 552 and 2 311 DEGs obtained during the green fruit stage, color turning stage and maturity stage of 'Ningqi No. 1' and 'Ningqi No. 7', respectively, among which 2 153, 2 050 and 1 825 genes were annotated in six databases, including gene ontology (GO), Kyoto encyclopedia of genes and genomes (KEGG) and clusters of orthologous groups of proteins (KOG). In GO database, 1 307, 865 and 624 DEGs of green fruit stage, color turning stage and maturity stage were found to be enriched in biological processes, cell components and molecular functions, respectively. In the KEGG database, the DEGs at three developmental stages were mainly concentrated in metabolic pathways, biosynthesis of secondary metabolites and plant-pathogen interaction. In KOG database, 1 775, 1 751 and 1 541 DEGs were annotated at three developmental stages, respectively. Searching the annotated genes against the PubMed database revealed 18, 26 and 24 DEGs related to the synthesis of active ingredients were mined at the green fruit stage, color turning stage and maturity stage, respectively. These genes are involved in carotenoid, flavonoid, terpenoid, alkaloid, vitamin metabolic pathways, etc. Seven DEGs were verified by RT-qPCR, which showed consistent results with transcriptome sequencing. This study provides preliminary evidences for the differences in the content of active ingredients in different Lycium barbarum L. varieties from the transcriptional level. These evidences may facilitate further exploring the key genes for active ingredients biosynthesis in Lycium barbarum L. and analyzing their expression regulation mechanism.

Objective : To investigate the effect of platelet particles on the extent of intestinal inflammation and in⁃ testinal mucosal permeability in mice with dextran sodium sulfate induced colitis. Methods : The experiment was divided into four groups : normal control group ( n = 10 , drinking sterile distilled water + intraperitoneal injection of 0. 9% sodium chloride solution) , PMPs group ( n = 10 , drinking sterile distilled water + intraperitoneal injection of PMPs) , DSS model group ( n = 10 , drinking DSS solution + intraperitoneal injection of 0. 9% sodium chloride solution) , and experimental group ( n = 15 , drinking DSS solution + intraperitoneal injection of PMPs) . Peripheral blood⁃derived PMPs suspension was collected from inflammatory bowel disease ( IBD) patients. A colitis model was constructed in mice by allowing them to freely drink a 5% DSS solution for 1 week , followed by continuous intraperitoneal injection of PMPs for 7 days. Disease activity index (DAI) scores was recorded daily and the severity of intestinal inflammation with histopathological scores (HI) was assessed by HE staining of colon samples at the end of the experiment. Myeloperoxidase (MPO) , neutrophil elastase (NE) , citrullinated histone H3 (citH3) , and free DNA levels were measured in colon homogenate , observe intestinal mucosal structure by transmission electron microscopy , and intestinal permeability was tested using fluorescein isothiocyanate⁃dextran (FITC⁃D) . Results: Compared with the normal control group , the colonic mucosa of mice in the PMPs group showed edema , severe destruction of epithelial structure , extensive aggregation of inflammatory cells , and increased overall HI score (P < 0. 01) ; the levels of inflammatory factors such as IL⁃1β and TNF⁃α in colonic tissue homogenates of mice in the PMPs group increased (P < 0. 05) , and the expression of NETs increased (P < 0. 05) ; the plasma FITC⁃D level of mice in the PMPs group significantly increased (P < 0. 05) , and the permeability of intestinal mucosa increased. Compared with the DSS group , the experimental group mice had higher plasma FITC⁃D levels ( P < 0. 05 ) and more electron microscopic colonic epithelial damage. Conclusion PMPs induces NETs formation in mice , promotes colonic inflammation in mice , increases intestinal mucosal permeability and aggravates intestinal inflammation in mice with DSS colitis.

Objective: To explore the impact of tennis on the visual health of primary school students, so as to provide a basis for myopia prevention. Methods: In September 2021, a total of 202 third grade students from Fengtai Affiliated School of Renmin University of China in Beijing were recruited, with 75 students in the intervention group and 127 students in the control group. In addition to attending the same cultural and physical education courses, the intervention group added a tennis course twice a week and tested their vision before the intervention (September 2021), middle (January 2022) and later (June 2022). Data collected at different time points in the two groups were analyzed by using independent sample t-test for comparison between blocks, and single factor repeated measurement ANOVA for analysis of time point factors. Results: After intervention, among male subjects, the average visual acuity of the left and right eyes in the intervention group were higher than that in the control group at the third visual acuity test (left eye:5.00±0.13,4.88±0.29, right eye:5.00±0.12,4.88±0.30, t =2.33, 2.36, P <0.05). Among female subjects, the second visual acuity test (left eye:5.03±0.17, 4.86±0.21, right eye:5.03±0.15, 4.85±0.23) and the third visual acuity test (left eye:4.97±0.13, 4.81±0.23, right eye:4.97±0.14, 4.82±0.24) showed that the average visual acuity of the left and right eyes in the intervention group were higher than that in the control group among females (second: t =3.84, 3.87, third: t =3.70, 3.46, P < 0.01 ). After intervention, the detection rate of visual impairment in both males and females control groups increased at three tests, with statistically significant differences ( χ 2=17.86, 34.77, P <0.01). In the first visual acuity test, there was no statistically significant difference in the detection rate of visual impairment between the control group and the intervention group for both males and females ( χ 2=0.01, 0.10, P >0.05). The third visual impairment detection rate of males in the intervention group was lower than that of the control group (20.00% vs 45.45%), while the second and third visual impairment detection rates of female students in the intervention group were lower than those of the control group (22.86% vs 54.00%; 28.57% vs 70.00%) ( χ 2=7.34, 8.24, 14.18, P < 0.01). Conclusions Tennis can alleviate and prevent the occurrence of myopia in primary school students to a certain extent. Sports such as tennis should be actively promoted to protect the visual health of primary school students.
