Objective: To investigate the prevalence of overweight and obesity among children and adolescents in Yangzhou City, and its association with screen behaviors, so as to provide scientific evidence for weight management among students. Methods: In May 2025, an electronic questionnaire survey was conducted among children and adolescents in Yangzhou City. A total of 3 722 participants were selected from grades 4 to 12 in 18 primary and secondary schools (108 classes) by using stratified cluster random sampling. The Chi square test was used to compare the differences in the detection rates of overweight and obesity among children and adolescents with 5 types of screen behaviors (watching TV, playing electronic games, scrolling short videos, screen based learning, electronic socializing) in different time groups each day (never, >0~<2 h, ≥2 h). Multivariate Logistic regression analysis was performed to examine the associations of five types of screen behaviors, presence of electronic devices in the bedroom, and screen use during meals on the weight status of children and adolescents. Results: The prevalence of overweight and obesity among children and adolescents was 37.3%. For all five types of screen behaviors, the differences in the distribution of overweight and obesity detection rates among children and adolescents across the three time spent categories were statistically significant ( χ 2=30.76- 70.78 , all P <0.01). After adjusting for confounding factors, multivariate Logistic regression analysis revealed that frequent or always using screens during meals( OR =1.63, 95％ CI =1.14~2.31), playing video games ( OR =1.28, 95% CI =1.11-1.48), browsing short videos ( OR =1.29, 95％ CI=1.09-1.54), and screen based learning ( OR =1.26, 95％ CI =1.10-1.44) were significantly associated with overweight and obesity among children and adolescents (all P <0.05). Conclusions Excessive screen use is positively correlated with the incidence of overweight and obesity in children and adolescents. Targeted interventions on screen behaviors among children and adolescents are therefore warranted.

ObjectiveTo describe the disposal process of the first imported case of Zika virus disease in Shanghai, and to provide a reference for the prevention and control of imported infectious diseases in the future. MethodsA retrospective review was conducted of the process by which epidemiological investigation, etiological testing, and case management were performed by the Shanghai municipal-and district-level Centers for Disease Control and Prevention (CDC) after one imported case of Zika virus disease was identified by Shanghai Customs. ResultsOn April 8th, 2025, customs authority at a certain airport in Shanghai identified a febrile inbound case (case A, female, 40 years old). An antecubital venous blood specimen was obtained and analyzed by nucleic acid testing for various vector-borne pathogens, by which Zika virus nucleic acid was found to be positive. On 9 April, the district CDC collected antecubital venous blood specimens again from Case A and her three accompanying travelers (B, C, and D), and nucleic acid testing was conducted for multiple mosquito-borne infectious diseases. Case A again tested positive for Zika virus nucleic acid, while Traveler D (male, aged 6 years) tested positive for dengue virus nucleic acid. The other two travelers tested negative. Case A and Traveler D were subsequently transferred to a designated district hospital for isolation and treatment. After discharge, both cases left China and returned to their overseas residence. ConclusionCase A was the first imported case of Zika virus disease in Shanghai. For cases with a history of living in endemic areas of multiple infectious diseases such as dengue virus, Zika virus and chikungunya virus, it is necessary to carry out rapid testing of multiple pathogens simultaneously to prevent missed diagnosis or misdiagnosis.

Objective: To analyze the prevalence and determinants of comorbid overweight/obesity and elevated blood pressure among primary and secondary school students in Yangzhou City, and to explore the association between sleep patterns, eating behavior and the comorbidity of overweight/obesity and elevated blood pressure, so as to provide reference for developing prevention strategies targeting common comorbidities in students. Methods: By using stratified cluster random sampling, a total of 8 735 primary and secondary school students were selected from 36 schools in six counties of Yangzhou from October to November 2023. Students underwent physical examinations and a questionnaire survey was conducted using the questionnaire on students health status and influencing factors. The Chi square test was used to compare the detection rate of comorbid overweight/obesity and elevated blood pressure in different groups of primary and secondary school students. The Logistic regression model was used to explore the association between sleep and dietary behaviors and their combined effects and coexistence. Results: The detection rate of comorbid overweight/obesity and elevated blood pressure among primary and secondary school students in Yangzhou was 9.85%, which was higher among boys (12.14%) than girls (7.59%)( χ 2=50.86, P <0.01). After controlling for gender, residence, educational stage, parental education, smoking, drinking, and moderate to vigorous exercise, multivariate Logistic regression analysis showed that irregular breakfast consumption and inadequate daily sleep were associated with a higher risk of comorbidities compared with regular breakfast consumption and adequate daily sleep among overall and primary school students (overall: OR =1.52, 95% CI =1.18- 1.96 , primary school students: OR =2.79, 95% CI =1.61-4.82)(both P <0.05). From the perspective of primary school students of different genders, the risk of comorbidities in girls who consumed breakfast irregularly and had inadequate daily sleep was 3.59 times higher than that in girls who consumed breakfast irregularly and had inadequate daily sleep (95% CI =1.65-7.82, P <0.01). Conclusion The sleep patterns and breakfast behaviors of primary and secondary school students are found to be associated with comorbid overweight/obesity and elevated blood pressure, especially in primary school girls.

Objective: To explore the association between sleep quality, sleep duration with blood pressure in primary and secondary school students with different nutritional status, so as to provide a reference for targeted intervention measures. Methods: By using stratified cluster random sampling method, a total of 10 871 students aged 7 to 18 years were selected from 36 primary and secondary schools in 6 counties of Yangzhou from October to November 2023. Physical examination and questionnaire survey were conducted respectively. Student Health Status and Influencing Factors Questionnaire was used to collected basic information. The overweight/obesity and sleep quality of primary and secondary school students were determined according to the Screening for Overweight and Obesity among School age Children and Adolescents and the Pittsburgh Sleep Quality Index scale. The χ 2 test was used to compare the prevalence of elevated blood pressure in different groups of primary and secondary school students. Multivariate Logistic regression model was used to explore the association between sleep and blood pressure in primary and secondary school students. Results: The prevalence of elevated blood pressure among primary and secondary school students in Yangzhou was 13.86 %, higher among boys (15.13%) than girls (12.62%) ( χ 2=14.30, P <0.01). The elevated blood pressure rate of obese and overweight primary and secondary school students were 26.98% and 14.90%, respectively, higher than 8.71% of non overweight and obese children ( χ 2=482.58, P <0.01). There were statistically significant differences in elevated blood pressure rate among primary and secondary school students in different sleep quality and sleep duration ( χ 2= 8.45, 71.58, P <0.05). After controlling for gender, residence, educational stage, parental education, sedentary time, the results of multiple Logistic regression analysis showed that no correlation between sleep quality and elevated blood pressure under different nutritional status was found among primary and secondary school students. In primary and secondary school students with obesity, prevalence of elevated blood pressure was higher among those with sleep duration <8 and 8 to <9 h/d ( OR=1.54, 1.72, P <0.05). However, there was no significant association found in the other groups ( OR=1.04-1.28, P >0.05). In gender stratification, sleep duration < 8, 8 to <9 and 9 to <10 h/d of obese boys were positively correlated with elevated blood pressure ( OR=1.97, 2.09, 1.86, P <0.05). Conclusion Among obese primary and secondary school students, sleep duration <9 h/d is associated with an increased risk of elevated blood pressure, especially among obese boys.

Objective:To construct four recombinant hemagglutinin (HA) antigens from seasonal influenza viruses and evaluate their immunogenicity in mouse models.Methods:HA coding sequences from four seasonal influenza virus strains Wisconsin (H1N1), Darwin (H3N2), Austria (B/Victoria lineage, BV) and Phuket (B/Yamagata lineage, BY) were optimized and synthesized, and then used to construct four recombinant plasmids. Recombinant baculoviruses were obtained through transformation and transfection. The expression of recombinant HA antigens was identified by SDS-PAGE and Western blot. The recombinant HA antigens were purified by nickel column affinity chromatography and intramuscularly administered to BALB/c mice after formulation with Al(OH) 3 or AddaVax adjuvant. Humoral immune responses were assessed by indirect ELISA and hemagglutination inhibition test, while cellular immune responses were evaluated by ELISPOT. Microneutralization test was used to detect the titers of serum antibodies in mice. Statistical analysis was performed using t test or non-parametric rank sum test. Results:PCR amplification and agarose gel electrophoresis confirmed the correct construction of the recombinant bacmids. Western blot showed verified the successful expression of the four recombinant antigens (H1-HA, H3N2-HA, BV-HA, and BY-HA). SDS-PAGE results showed that the purity of all four recombinant HA antigens exceeded 95%. After three-dose immunization, the total IgG levels in mice immunized with the recombinant H1N1-HA, H3N2-HA, or BV-HA formulated with AddaVax adjuvant were higher than those in the corresponding groups immunized with the same recombinant antigen alone (all P<0.05). The secretion levels of IFN-γ, IL-2, and IL-4 in the group receiving the mixture of all four recombinant HA antigens formulated with AddaVax adjuvant were higher than those in the group immunized with a commercial quadrivalent split influenza vaccine (all P<0.01). Results of the microneutralization test showed that the antibody titer in the quadrivalent split influenza vaccine group was 1∶225, whereas the titer in the group immunized with the mixture of four recombinant HA antigens formulated with AddaVax adjuvant could reach up to 1∶1 200. Conclusions:In this study, four recombinant seasonal influenza virus HA antigens are successfully expressed and demonstrated good immunogenicity in mice when formulated AddaVax adjuvant.

In recent years, rituximab has been gradually used in the treatment of idiopathic membranous nephropathy (IMN). Compared with traditional treatments, the safety and effectiveness of rituximab in the treatment of IMN have been confirmed, which induces remission in 60%-80% of patients. For the remaining 20%-40% patients, several mechanisms can explain rituximab resistance: decreased rituximab bioavailability; internalized by targeted B cells; the generation of anti-rituximab antibody; chronic and irreversible damage to the glomerular filtration barrier; autoreactive B-cell clones in secondary lymphoid organs that cannot be effectively eliminated. The treatment of patients with rituximab-refractory IMN remains controversial and challenging. The recognition of IMN as an antibody-mediated autoimmune disease has rationalized the use of immunosuppressive drugs such as B cell-targeted therapies, plasma cell-targeted therapies, and complement inhibitors. This review mainly summarizes recent advances in the understanding of the physiological mechanisms of rituximab resistance, and in the management of rituximab-refractory IMN, aiming to aid in the clinical management of IMN.

Objective:To explore the long-term efficacy of a modified unilateral cutaneous ureterostomy in bladder cancer patients receiving radical cystectomy.Methods:The medical data of 104 bladder cancer patients who underwent ureterostomy in our hospital from Janurary 2013 to December 2020 were retrospectively analyzed. The patients were divided into unilateral and bilateral group. The unilateral group contained 66 cases, with 53 males and 13 females, average age (71.8±9.8) years, body mass index (BMI)(23.3±3.2)kg/m 2. The bilateral group contained 38 cases, with 33 males and 5 females, average age (75.1±10.8) years; BMI (22.7±3.0)kg/m 2. There was no significant difference in the above characteristics between the two groups ( P>0.05). The pathology, survival status, long-term complications between the two groups were compared. Quality of life was assessed during follow-up using the European Core Questionnaire for Quality of Life in Cancer Patients (EORTC QLQ-C30). Results:The unilateral group contained 46(69.7%) muscle invasive bladder cancer (MIBC) cases, 15 (22.7%) cases with lymph node metastasis, 7 (10.6%) cases with distant metastasis. The bilateral group contained 24(63.2%) muscle invasive bladder cancer(MIBC) cases, 6 (15.8%) cases with lymph node metastasis, 2 (5.3%) cases with distant metastasis. There was no significant difference in disease specific survival between the two groups ( P>0.05). During the follow-up, the incidence of overall complication rate in the unilateral group was significantly lower than that in the bilateral group [43.9% (29/66) vs. 63.2% (24/38), P<0.001]. The incidence of pyelonephritis in unilateral group was significantly lower than that in the bilateral group [16.6%(11/66) vs. 42.1%(16/38), P=0.006]. There was no statistical significance in terms of quality of life before operation in the two groups. After operation, both physical function score[(54.9±7.1) vs.(49.2±6.7)] and emotional function score [(63.1±6.4) vs.(59.9±6.7)] in unilateral group were higher than that in bilateral group ( P<0.05). Conclusions:The modified unilateral cutaneous ureterostomy could achieve relatively low complication rate, and improve the quality of life to some extent compared with bilateral ureterostomy.

OBJECTIVE: To explore the genetic basis for a patient featuring developmental delay. METHODS: The patient and her parents were subjected to G- and C-banded chromosomal karyotyping analysis. The proband was also analyzed by single nucleotide polymorphism microarray (SNP-array). The result was verified by using fluorescence quantitative PCR (qPCR). RESULTS: The proband's karyotype was ascertained as 46,XX, r(15)(p11.2q26.3)[92]/45,XX,-15[9]/46,XX, dic r(15)(p11.2q26.3;p11.2q26.3)[4]. SNP-array revealed that she has carried a de novo deletion at 15q26.3 (98 957 555-102 429 040) spanning approximately 3.4 Mb, which encompassed the IGF1R gene. qPCR has confirmed haploinsufficiency of exons 3, 10 and 20 of the IGF1R gene. Both of her parents had a normal karyotype. CONCLUSION The abnormal phenotype of the proband may be attributed to the microdeletion at 15q26.3, in particular haploinsuffiency of the IGF1R gene and instability of the ring chromosome. Cytogenetic method combined with SNP-array and qPCR can efficiently delineate chromosomal aberrations and provide accurate information for clinical diagnosis and genetic counseling.

Objective:To investigate the effectiveness of surgical treatment for patients with T 4 stage prostate cancer. Methods:The clinical data and prognosis of 18 patients with T 4 stage prostate cancer treated in Shanghai Tenth People's Hospital from July 2013 to December 2019 were retrospectively analyzed. The average age of these 18 patients was 68.3 (53-81)years. 10 patients were castration resistant prostate cancer (CRPC) and 8 patients were hormone-sensitive prostate cancer (HSPC). 10 CRPC patients were treated with surgical treatment due to bladder clot packing and/or lower urinary tract obstruction. 8 HSPC patients had severe hematuria, severe dysuria and local symptoms. The KPS scores of all patients were ≥80 points with an average score of 84 (80-90). The average QOL score of 18 patients was 28 (21-32). 2 cases in 18 patients underwent total pelvic resection for rectal invasion (one CRPC and one HSPC). 7 cases underwent radical cystoprostatectomy for ureteral invasion (5 cases of CRPC, 2 cases of HSPC), 9 cases underwent bladder preservation surgery for bladder neck invasion (4 cases of CRPC, 5 cases of HSPC), of which 4 cases of enlarged lymph node dissection were all HSPC patients. Results:All cases of T 4 stage prostate cancer patients operation were successfully completed, the average operation time was 256 (219-310)min and the median intraoperative blood loss was about 300 (250-350)ml. Four of them (3 cases of CRPC and 1 case of HSPC) received blood transfusion after operation. The average postoperative hospital stay was 21(11-37) days. All 18 cases were followed up and the median follow-up time was 23.8 months. There was no perioperative death, and no bladder-preserving patients had true urinary incontinence or bladder outlet stenosis.2 CRPC cases died 8 and 15 months after surgery respectively, 7 patients were PSA relapse treated with docetaxel or abiterone therapy, and 1 HSPC patient with rectal invasion was followed up for 58 months after total pelvic resection, the PSA level was still 0.003ng/ml, no distant metastasis was found. 8 cases of hormone-sensitive patients were treated with endocrine therapy, and PSA was less than 0.2 ng/ml. The average QOL of 18 patients 3 months after operation was 37 points (25-45), which was significantly higher than that before operation. The average maximum urine flow rate of patients with bladder preservation was 23(19-25)ml/s. Conclusions:For T 4 stage prostate cancer, surgical treatment is feasible and safe for doctors with extensive surgical experience. For CRPC patients, the surgery can significantly improve short-term symptoms and quality of life, and long-term benefits need to be further evaluated with a large sample. For HSPC patients, it can not only improve clinical symptoms and QOL of patients, but also provide long-term benefits.
