Objective: To investigate the willingness to accept preventive treatments and its related factors among college freshmen with latent tuberculosis infection (LTBI), so as to provide the evidence for preventive treatment intervention measures for students with LTBI. Methods: Cluster sampling method was used to select 368 LTBI freshmen from 8 colleges and universities in Changzhou in September 2023, who conducted a questionnaire survey on the willingness to receive preventive treatment. General demographic data were collected and relevant data were collected using tuberculosis knowledge scale, General Anxiety Disorder-7 (GAD-7), Patient Health Questionnaire-9 (PHQ-9), Adaptation, Partnership, Growth, Affection and Resolve (APGAR), and a self developed Stigma Scale. A binary Logistic regression model was constructed with the willingness to accept preventive treatment as the dependent variable to analyze the willingness to accept preventive treatment and the influencing factors. Results: A total of 253 LTBI college freshmen were willing to take preventive treatment, the acceptance rate was 68.75%. The rate of willingness to accept preventive treatment for LTBI was higher among students whose fathers had an education level of high school, compared to those whose fathers had an education level of junior high school or below ( OR =2.16, P <0.05). LTBI students whose per capita family income was >5 000-10 000 yuan and >10 000 yuan were more willing to accept LTBI preventive treatment than those whose per capita family income was <3 000 yuan ( OR =2.72, 4.46, P <0.05). LTBI students who engaged in physical exercise for more than 2 hours per week were more willing to accept than those who exercised less than 0.5 hours per week ( OR =1.91, P <0.05). LTBI students with high levels of tuberculosis knowledge and stigma were more likely to receive preventive treatment ( OR =1.18, 1.11, P < 0.05). LTBI students with high PHQ-9 ( OR =0.85) and GAD-7 ( OR =0.92) scores were more likely to refuse preventive treatment ( P <0.05). Conclusion The present study revealed a moderate level of willingness of LTBI students to preventive treatment in Changzhou City, and the acceptance is affected by family factors, healthy lifestyles, tuberculosis knowledge and psychological status.

Objective:To analyze the value of 68Ga-fibroblast activation protein inhibitor (FAPI)-04 PET/CT in the detection of myocardial injury in patients treated with anti-tumor therapy. Methods:A retrospective study was conducted on 164 patients who underwent 68Ga-FAPI-04 PET/CT to evaluate the efficacy of anti-tumor therapy in Renji Hospital, School of Medicine, Shanghai Jiao Tong University between August 2021 and March 2024. The patients were divided into 68Ga-FAPI-04-positive group ( n=63, 36 males, 27 females, age (66.7±9.6) years) and 68Ga-FAPI-04-negative group ( n=101, 42 males, 59 females, age (55.2±14.1) years) based on the uptake of left ventricular myocardium (LVM). Moreover, FAPI-04 uptake was analyzed based on different types and locations, and the corresponding SUV max differences were analyzed by Kruskal-Wallis rank sum test. The differences of SUV max between 68Ga-FAPI-04-positive group and 68Ga-FAPI-04-negative group were analyzed by Mann-Whitney U test. The clinical factors such as gender, age, body mass index (BMI), previous history of coronary heart disease, left ventricular ejection fraction (LVEF), smoking history, hypertension, diabetes, cancer types and immune checkpoint inhibitors (ICIs) treatment were collected, and their predictive values for LVM 68Ga-FAPI-04 uptake were investigated by the binary logistic regression analysis. Results:Fifty patients of the 68Ga-FAPI-04-positive group (79.4%, 50/63) showed focal uptake of LVM, 7 patients (11.1%, 7/63) showed multifocal myocardial uptake, and 6 patients (9.5%, 6/63) showed diffuse myocardial uptake. A total of 127 uptake lesions were found, and most of them were located in the septum (37.8%, 48/127). The SUV max of LVM in 68Ga-FAPI-04-positive group and 68Ga-FAPI-04-negative group were 4.00(3.10, 5.40) and 1.31(1.20, 1.40) respectively ( z=-10.82, P<0.001). Differences of the SUV max among focal uptake group, multifocal myocardial uptake group, and diffuse myocardial uptake group were not significantly different (4.00(3.00, 5.10) vs 7.60(3.60, 9.30) vs 3.95(3.05, 5.05); H=3.81, P=0.149). There is no statistically significant difference either in FAPI uptake among different sites of LVM ( H=1.51, P=0.825). Age, previous history of coronary heart disease, BMI, LVEF and ICIs treatment were independent predictive factors for positive 68Ga-FAPI-04 uptake in the LVM (odds ratio ( OR) values: 0.87-10.43, all P<0.05). Conclusion:68Ga-FAPI-04 PET/CT is a potential new imaging method for the visualization of myocardial injury in patients with anti-tumor therapy.

Objectives: . Despite the efficacy of surgical treatments, the high rate of recurrence in juvenile nasopharyngeal angiofibroma (JNA) after surgery remains an unresolved problem. The present study comprehensively analyzed the risk factors and characteristics of JNA recurrence, providing clinical guidance for reducing recurrence. Methods: . A total of 123 patients who underwent surgery for JNA between 1997 and 2019 at a single hospital were analyzed retrospectively. Univariate and multivariate analyses were used to assess the clinical risk factors for the recurrence of JNA. The relapse-free survival and annual cumulative recurrence rates were analyzed for subgroups defined according to clinical parameters. Results: . After screening, 78 of the 123 patients were included in the present study. The main risk factors associated with JNA recurrence included the year of diagnosis, tumor size, sphenoid bone invasion, Radkowski stage, surgical approach, and intraoperative bleeding. Importantly, the surgical approach and sphenoid bone invasion were independent prognostic factors affecting recurrence. Patients who underwent endoscopic surgery without sphenoid bone invasion exhibited longer relapse-free survival. In the present study, the overall cumulative recurrence rate of JNA was 38.7%, and recurrence occurred mainly in the first year after the initial surgery. Conclusion . Endoscopic surgery achieved better relapse-free survival in JNA patients, and patients with sphenoid bone invasion should be carefully explored to avoid residual JNA. The recurrence rate of JNA differed among subgroups defined based on clinical parameters and was highest in the first year after surgery. Computed tomography or magnetic resonance imaging, along with close follow-up, should be performed strictly within 1 year after the primary operation.

In order to investigate developmental coordination disorder (DCD) of kindergarten children in Zhejiang province, 200 ordinary kindergartens were randomly selected by stratified random sampling in 11 prefecture-level cities of Zhejiang Province, and 38 900 children from 1 000 classes in each grade were then randomly selected into the study from June 2019 to December 2019. The Little DCD Questionnaire and a self-designed questionnaire were used to screen the DCD of those children. There were 36 807 valid questionnaires, and 6.50% (2 391/36 807) of them were positive results. The results showed that boy, age ≤5 years, overweight or obesity, left handedness, comorbidity with motor or developmental disorders and premature infants were risk factors of DCD in children. As for parents and families, maternal gestational age<20 years, maternal overweight or obesity before pregnancy, low-middle level education of parents, direct family and low income of family were also associated with DCD in children. Therefore, it is necessary to conduct early prevention and intervention strategies targeting on identified risk factors among relevant population.

To effectively solve the serious impact of high oil in the kitchen wastewater on the downstream treatment process, an excellent oil-degrading strain Aeromonas allosaccarophila CY-01 was immobilized to prepare Chitosan-Aeromonas pellets (CH-CY01) by using chitosan as a carrier. Oil degradation condition and efficiency of CH-CY01 pellets were assessed. The growth of immobilized CH-CY01 was almost unaffected, and the maximum degradation rate of soybean oil was 89.7%. Especially at 0.5% NaCl concentration, oil degradation efficiency of CH-CY01 was increased by 20% compared with free cells. In the presence of a surfactant (sodium dodecylbenzene sulfonate) at 1 mg/L, the degradation efficiency of oil by CH-CY01 was increased by 40%. Moreover, using the high-oil catering wastewater as the substrate, more than 80% of the solid oil was degraded with 1% (V/V) CH-CY01 pellets treatment for 7 days, significantly higher than that of free cells. In summary, immobilized CH-CY01 significantly improved the efficiency of oil degradation.

Objective:To explore the clinical effect of moderate exercise therapy and fracture liaison service in osteoporotic hip fracture.Methods:From June 2018 to June 2020, 120 patients with osteoporotic hip fracture admitted to Nanjing Hospital Affiliated to Nanjing Medical University were selected. The patients were divided into study group and control group by random number table method, 60 cases in each group. The control group was treated with routine nursing and moderate exercise therapy, and the control group was treated with fracture liaison service, clinical observation and comparison of treatment compliance, bone mineral density (BMD), Numerical Rating Scale (NRS) score and nursing satisfaction before and after intervention.Results:The BMD and NRS scores in the study group were (0.90±0.25) g/cm 2, (1.0±0.3) points, higher than those in the control group (0.80±0.18) g/cm 2, (1.0±0.25) points. The difference was statistically significant ( t values were 2.514, 2.547, P<0.05). The total compliance rate and nursing satisfaction of the study group were 93.30% (56/60) and 95.00% (57/60) respectively, which were significantly higher than 80.00% (48/60) and 83.33% (50/60) of the control group. The difference was statistically significant ( χ 2 values were 4.615, 4.227, P<0.05). Conclusion:Moderate exercise therapy and fracture contact service intervention can effectively improve bone mineral density and total compliance rate, relieve pain and improve nursing satisfaction.

Objective:To investigate the risk factors for different types of single subcortical infarction (SSI) in middle cerebral artery territory and the risk factors for early neurologic deterioration (END).Methods:Patients with SSI in middle cerebral artery territory admitted to the Department of Neurology, People's Hospital Affiliated to Jiangsu University from January 2020 to April 2021 were enrolled retrospectively. According to the distribution of infarction, the patients were divided into proximal SSI (pSSI) and distal SSI (dSSI). The demographics, vascular risk factors and baseline clinical data were collected. END was defined as new signs and/or symptoms of neurological deficit or aggravation of any neurological deficit within 2 weeks after onset. Multivariate logistic regression analysis was used to determine the independent risk factors for pSSI and END. Results:Seventy-six patients with acute SSI in the middle cerebral artery territory were included, 41 patients (53.9%) in the pSSI group, 35 (46.1%) in the dSSI group; 13 (17.1%) in the END group, and 63 (82.9%) in the non-END group. There were no significant differences in age, gender, vascular risk factors and baseline National Institutes of Health Stroke Scale score between the pSSI group and the dSSI group. The total cholesterol, fasting blood glucose levels and the ratio of pSSI in the END group were significantly higher than those in the non-END group ( P<0.05), while the high-density lipoprotein cholesterol level was significantly lower than that of the non-END group ( P<0.05). Multivariate logistic regression analysis showed that pSSI was an independent risk factor for the occurrence of END in patients with SSI (odds ratio 6.75, 95% confidence interval 1.26-36.23; P=0.026). Conclusion:There was no significant difference in risk factors between pSSI and dSSI, but patients with pSSI were more prone to END.

Objective To seperate fetal nucleated red blood cells (fNRBCs) from the whole maternal peripheral blood effectively by designing a circular channel microfluidic chip. Methods A microfluidic chip is designed by utilizing the margination in blood flow and the specific adhesion characteristics of immuno-agent anti-CD147. With the whole umbilical cord blood, the effects of different shear forces on the enrichment of fNRBCs was studied by immunofluorescence counting. Results Increasing shear rate in microfluidic chip could improve the number of captured fNRBCs compared with the static adhesion. With the increase of shear rate of blood flow, the number of the captured cells increased at first, and then decreased. Conclusions The use of microfluid chip can effectively seperate fNRBCs from the whole blood. The results provide an experimental reference for the non-invasive prenatal diagnosis research and the exploration on the mechanism of fetal cell migration.

Objective To investigate the effect of exercise diary on arm exercise compliance ofpatients with peripherally inserted centralcatheter (PICC). Methods Thirty patients with PICC hospitalized in our hospital from June to August in 2017 were selected as the control group, where the patients received guidance on functional exercises through arm exercise videos and routine methods. Another thirty-two patients hospitalized in our hospital from September to November of 2017 were selected as the observation group, where in addition to the same treatment as in the control group and these patients received interventions using their self-designed exercise diary for a total of 31 days. Their compliance with functional exercises before and after intervention and the incidences of venous thrombosis after intervention were compared between the two groups. Results After interventions, the compliance rate of arm exercises in the observation group was significantly higher than that of the control group (90.6% vs. 26.7%, P＜0.05). The incidence of venous thrombosis in the observation group was significantly lower than that of the control group (3.1% vs. 30.0% , P＜0.05). Conclusions Exercise diary can improve the arm exercise compliance of PICC patients and prevent the occurrence of venous thrombosis. It is worthy of clinical application and promotion.
