Objective: To understand the changing trends and related factors of knowledge, attitude and practice (KAP) regarding the three major infectious diseases (acquired immunodeficiency syndrome, tuberculosis, hepatitis B) among freshmen in Jiangsu from 2019 to 2022, so as to provide a reference basis for the health education of infectious diseases in schools. Methods: From 2019 to 2022, a total of 33 944 freshmen from 20 universities in Jiangsu Province were randomly selected for four consecutive years to investigate their KAP levels online through self designed questionnaires on three major infectious diseases. The multiple linear regression model was used to analyze the changing trends of students KAP levels of the three major infectious diseases, and to explore the influencing factors of KAP. Results: From 2019 to 2022, the knowledge scores(18.0±3.1,18.4±3.2,18.7±3.2,18.8±3.2), related to the three major infectious diseases showed an upward trend ( F=436.50, P <0.01), and the positive attitude reporting rates were 81.77%, 81.46%, 82.68% and 81.74%, respectively. The reporting rates of positive practice were 80.11%, 79.25%, 79.08 % and 79.04%, respectively. Multiple linear regression showed that school type, parental education level, mother s occupation, average income per person in family and living arrangements during high school all had an impact on the knowledge ( β = -1.510 -0.559), attitudes ( β =-0.043-0.065) and practice ( β =-0.028-0.027) of the three major infectious diseases ( P < 0.05 ). The family residence areas only affected the reporting rate of positive attitude scores ( β =0.002-0.065), and whether only children or not affected the reporting rate of positive practice scores ( β =0.009)( P <0.05). The knowledge score showed an upward trend ( β= 0.297, P <0.01), the positive attitude reporting rate showed no statistically significant change ( β=0.001, P =0.22), and the positive practice reporting rate showed a downward trend ( β=-0.005, P <0.01). Conclusions Freshman in Jiangsu Province from 2019 to 2022 have shown a separation in KAP scores regarding the three major infectious diseases. Targeted measures should be taken to improve their health practice level.

OBJECTIVE: To investigate the effectiveness of TiRobot-assisted minimally invasive treatment for fragility fractures of the pelvis (FFP) in elderly patients. METHODS: A retrospective analysis was conducted on the clinical data of 176 patients with FFP who were admitted between July 2018 and July 2024 and met the selection criteria. Among them, 95 patients underwent TiRobot-assisted closed reduction and minimally invasive cannulated screw fixation (robot group), while 81 patients underwent traditional open reduction and plate screw fixation (control group). There was no significant difference in baseline data such as gender, age, fracture classification, disease duration, and preoperative visual analogue scale (VAS) pain scores between the two groups ( P>0.05). The following parameters were recorded and compared between the two groups, including operation time, intraoperative blood loss, intraoperative transfusion rate, volume of intraoperative blood transfusion, maximum incision length, hospital stay, maximum residual displacement, reduction quality, fracture healing time, incidence of complications, VAS scores, Majeed pelvic function scores, and functional grading. RESULTS: All surgeries in both groups successfully completed. The robot group exhibited significantly shorter operation time, reduced intraoperative blood loss, lower intraoperative transfusion rate, smaller volume of intraoperative blood transfusion, shorter maximum incision length, and shorter hospital stay compared to the control group ( P<0.05). In the robot group, a total of 14 INFIX internal fixation frames and 280 cannulated screws were implanted, among which 250 screws were rated as excellent, 17 as good, and 13 as poor, resulting in a screw placement excellent and good rate of 95.36%. Radiological review revealed that the excellent and good rate of reduction quality was in 91.58% (87/95) in the robot group and 81.48% (66/81) in the control group, with no significant difference in postoperative maximum residual fracture displacement or reduction quality between the two groups (P>0.05). All patients in both groups were followed up 12-66 months, with an average of 28.9 months, and there was no significant difference in follow-up time between the two groups ( P>0.05). The fracture healing time in the robot group was significantly shorter than that in the control group ( P<0.05). At last follow-up, both groups showed significant improvement in VAS scores compared to preoperative values ( P<0.05); the change values of VAS scores, Majeed scores, and the excellent and good rate of Majeed pelvic function were significantly higher in the robot group than in the control group ( P<0.05). Regarding postoperative complications, there was no significant difference between the two groups in terms of gait changes, secondary surgeries, heterotopic ossification, incision infections, walking difficulties, internal fixation failure, or mortality rates ( P>0.05); however, the incidence of delayed wound healing was significantly lower in the robot group than in the control group ( P<0.05). CONCLUSION TiRobot-assisted minimally invasive treatment of elderly FFP is superior to traditional open reduction and internal fixation in terms of surgical trauma control, postoperative rehabilitation speed, and functional recovery.

Objective:To investigate the effect of protein tyrosine phosphatase D(PTPRD)demethylation on the proliferation,migration,and chemoresistance of gastric cancer(GC)cells through the phosphatidyl inositol 3 kinase/protein kinase B/mammalian target of rapamycin(PI3K/Akt/mTOR)pathway.Methods:The gastric cancer MKN-74 and MKN-45 cells,as well as human gastric mucosal epithelial GES-1 cells,GES-1 were cultured in vitro and PTPRD expression was detected.MKN-45 cells and their drug-resistant variant MKN-45/5-FU cells were routinely cultured and transfected with various vectors:PTPRD empty vector(NC group,NC/5-FU group),PTPRD overexpressing adenovirus(PTPRD group,PTPRD/5-FU group),shRNA empty vector(sh-NC group,sh-NC/5-FU group),shRNA PTPRD lentivirus(sh-PTPRD group,sh-PTPRD/5-FU group),and PTPRD overexpressing adenovirus+10 μmol/L 740Y-P treatment(PTPRD+740Y-P group,PTPRD+740Y-P/5-FU group).MTT assay and wound healing assay were used to assess cell proliferation and migration.Cell autophagy levels were assessed using autophagy assay,and the expression of epithelial-mesenchymal transition(EMT)and PI3K/Akt/mTOR pathway related proteins was detected using western blot(WB).MKN-45 cells were treated with 0,2.5,5,10,20 and 40 μmol/L 5-aza solutions,and the PTPRD mRNA expression and cell proliferation in MKN-45 cells were detected using qPCR and MTT assays.Results:PTPRD mRNA and protein were significantly downregulated in gastric cancer cells(P<0.05).Compared with the MKN-45 group,the numbers of autophagosomes and autophagosomes,as well as the protein expression of PTPRD,E-cadherin,and BAX significantly increased in the PTPRD group(all P<0.05),while cell proliferation,migration rate,and protein expression of p-PI3K,vimentin,p-Akt,and p-mTOR decreased significantly(all P<0.05);However,in the sh-PTPRD group,cell proliferation activity,migration rate,and protein expression of p-PI3K,vimentin,p-Akt,and p-mTOR increased notably,while the quantity of autophagosomes,autophagosomes,and protein expression of PTPRD,E-cadherin,and BAX decreased(all P<0.05).Compared with the PTPRD group,the PTPRD+740Y-P group showed an increase in cell proliferation activity,migration rate,protein expression of p-PI3K,vimentin,p-Akt,and p-mTOR(all P<0.05),and a decrease in number of autophagosomes,autophagosomes,and protein expression of PTPRD,E-cadherin,and BAX(all P<0.05).With the increase of 5-aza concentration,the mRNA expression of PTPRD in MKN-45 cells increased(P<0.05),while the cell proliferation activity decreased(P<0.05).Compared with the MKN-45/5-FU group,the cell migration rate and proliferation activity decreased in PTPRD/5-FU group,while the sh-PTPRD/5-FU group showed an increase in cell migration rate and proliferation activity(all P<0.05).Compared with the PTPRD/5-FU group,the PTPRD+740Y-P/5-FU group showed an increase in cell migration rate and proliferation activity(all P<0.05).Conclusion:PTPRD is downregulated in GC cells,and its demethylation may inhibit proliferation and migration of GC cells and enhance chemosensitivity by suppressing the PI3K/Akt/mTOR pathway.

Objective: To explore the efficacy and safety of clonidine adhesive patch in Tourette syndrome (TS) patients with comorbid attentiondeficit/hyperactivity disorder (ADHD). Methods: This study was conducted on a sample of children and adolescents with TS who had comorbid ADHD between May 2012 and March 2015. The patients were diagnosed according to Diagnostic and Statistical Manual of Mental Disorders Fourth Edition, and were randomly assigned to four different dose groups: 1.0 mg/week, 1.5 mg/week, 2.0 mg/week and placebo group, and the symptom was evaluated by Swanson, Nolan, and Pelham Rating Scale, Version IV (SNAP-IV) and Yale Global Tic Severity Scale scales every 2 weeks. The primary outcome was tic disorders (TD) effective rate at week 8. Results: One hundred and twenty-seven TS patients with comorbid ADHD in 2.0 mg/week (n=35), 1.5 mg/week (n=27), 1.0 mg/week (n=36) and placebo groups (n=29) were included in this subgroup analysis. The TD effective rate of the 2.0 mg, 1.5 mg, and 1.0 mg groups at week 8 were significantly better than that in placebo group (85.7%, 81.5%, and 86.1% vs. 20.7%, all p<0.0001). All groups demonstrated significant improvements in SNAP-IV total scale scores compared to baseline (p=0.0004), with treatment groups showing only a trend for better performance compared to placebo group at week 8, without statistical differences (22.1±15.41, 21.3±11.96, and 21.2±12.48 vs. 26.0±13.37, p=0.3385). A total of 9 adverse reactions occurred, all recovered spontaneously without additional medication. Conclusion Clonidine adhesive patch could safely and effectively reduce the tic symptoms of TS patients with comorbid ADHD, and might be potentially helpful in the ADHD symptoms control.

Objective:To explore the assessment value of quantitative parameters of dynamic contrast-enhanced magnetic resonance imaging(DCE-MRI)and tumor markers in assessing the curative effect of neoadjuvant chemotherapy for breast cancer.Methods:A total of 75 patients with breast cancer who received neoadjuvant chemotherapy combined with surgical intervention in Jining No.1 People's Hospital from May 2019 to May 2022 were selected,and they were divided into effective group(54 cases)and ineffective group(21 cases)according to the Response Evaluation Criteria In Solid Tumour(RECIST).The Ve,Kep and Ktrans of DCE-MRI quantitative parameters and CEA,CA125 and CA15-3 levels of tumor markers between two groups were compared before and after chemotherapy,and the receiver operating characteristics(ROC)curve was adopted to analyze the predictive efficiency of each diagnostic method.Results:After chemotherapy,the differences of the Ve,Kep and Ktrans of quantitative parameters between the two groups were significant(t=7.237,51.695,16.879,P<0.05),respectively.The differences of the CEA,CA125 and CA15-3 of tumor markers between two groups were significant(t=44.201,6.736,6.885,P<0.05),respectively.The AUC value of combined prediction of 6 indicators included Ve,Kep,Ktrans,CEA,CA125 and CA15-3 was 0.979 in predicting the curative effect of neoadjuvant chemotherapy for breast cancer,which was significantly higher than the AUC value of each alone indicator,and the differences of them were statistically significant(Z=2.993,2.679,2.510,2.731,3.215,3.071,P<0.05),respectively.Conclusion:The combination of tumor markers and DCE-MRI quantitative parameters can better predict the curative effect of neoadjuvant chemotherapy for breast cancer,which can indirectly assess the prognosis.

Diabetes mellitus type 2 might cause mild cognitive impairment in its advanced stages,potentially progressing to dementia.Diabetic cognitive impairment(DCI)stands as a chronic complication of diabetes mellitus,with its underlying pathogenesis still remaining elusive.Research has revealed that gut microbiota dysbiosis influenced the central nervous system through the"microbiota-gut-brain axis",thereby contributing to the progression of cognitive impairment.Therefore,the regulation of gut microbiota emerges as a promising approach to the prevention and treatment of DCI.This article comprehensively reviews the mechanisms through which gut microbiota influences DCI.Furthermore,it delves into experimental studies exploring targeted therapies for gut microbiota,including probiotics,fecal microbiota transplantation,dietary and nutrient interventions,as well as traditional Chinese medicine.These studies not only address diabetes-related cognitive impairment but also consider aspects such as glycolipid metabolism and inflammation.The insights gleaned from these studies provide valuable guidance for the clinical application of gut microbiota-targeted intervention in DCI.

Diabetes mellitus and its consequences have gained increased attention with the incidence rate rising.Diabetic cognitive impairment (DCI), a neurological consequence of diabetes mellitus, has shown a significant increase in recent years, and its related mechanisms need to be elucidated. Short-chain fatty acids (SCFAs), which are metabolites of dietary fiber fermented by gut microbiota and play a significant role in the "microbial-gut-brain axis", have become a popular research topic in recent years for their link to diabetes mellitus and brain function. Therefore, it is important to explore the relationship between SCFAs and DCI. This review summarized the changing characteristics of SCFAs in diabetes mellitus, cognitive impairment and DCI populations, as well as the mechanisms of SCFAs in DCI, which include glucose-lipid metabolism, pathological protein aggregation, inflammation, and mitochondrial autophagy.Future studies should address the common pathophysiological mechanisms of diabetes mellitus and cognitive impairment, in order to explore the effects of different types and doses of SCFAs in DCI and the underlying mechanisms, so as to provide a theoretical basis for the prevention and treatment of the disease in the context of the "co-morbidity model" .

Objective: To understand the trends and associated factors of tuberculosis knowledge and behavior among freshmen from Jiangsu Province, 2019 to 2022, so as to provide theoretical support for the popularization of tuberculosis knowledge and the prevention and control of tuberculosis in universities. Methods: From 2019 to 2022, a total of 33 944 freshmen from 20 universities in Jiangsu Province were selected by stratified random sampling, and tuberculosis knowledge and behavior were surveyed online using a selfdesigned questionnaire. Oneway variance trend test and multiple linear regression analysis were used to analyze the trend of knowledge and behavior levels, and a multiple linear regression model was used to analyze the influencing factors. Results: The overall awareness rate of tuberculosis among freshmen from Jiangsu Province was 90.6%, and the overall awareness rates from 2019 to 2022 were 88.4%, 90.4%, 91.7%, and 91.8%, respectively. The overall behavioral accuracy rate was 92.3%, with the annual rates from 2019 to 2022 being 91.8%, 92.3%, 92.7%, and 92.4%, respectively. Both the awareness rate and accuracy behavior rate increased annually (F=216.67, 11.75, P<0.01). The multiple linear regression analysis showed that school type, ethnicity, fathers educational level, mothers educational level, mothers occupation, family per capita monthly income, and living arrangement in high school affected both personal knowledge awareness rate and personal behavioral accuracy rate (β=-0.047-0.035, P<0.01), while region, gender, family residence, and being an only child only affected behavioral accuracy rate (β=-0.003-0.032, P<0.05). Conclusions The tuberculosis knowledge and behavior levels of freshmen from Jiangsu Province have been increasing by year. Targeted health education should be carried out based on the relevant influencing factors to further enhance the tuberculosis prevention and control literacy.
