Objective To evaluate the safety of the 13-valent pneumococcal polysaccharide conjugate vaccine (tetanus toxoid/diphtheria toxoid) (PCV13-TT/DT) among age-eligible children in Tianjin through a combination of active and passive surveillance methods. Methods From July 15, 2023, to August 31, 2024, active surveillance for adverse events following immunization (AEFI) was conducted among recipients of PCV13-TT/DT at 18 selected vaccination clinics in Tianjin. Recipients were monitored through on-site observation or telephone follow-up within 30 minutes after vaccination and on days 1, 3, 7, and 28. Passive surveillance for AEFI was conducted among recipients of PCV13-TT/DT at other vaccination clinics across the city. The incidence of AEFI was analyzed using descriptive epidemiological methods. Results A total of 24 916 recipients of PCV13-TT/DT were observed, with 440 AEFI cases reported, resulting in an overall incidence rate of 176.59 per 10 000. The incidence rate of AEFI in active surveillance was 813.79 per 10 000, significantly higher than that in passive surveillance (20.49 per 10 000; P< 0.001). The incidence rates of general reactions, abnormal reactions, and coincidental cases in active surveillance were 744.44 per 10 000, 8.16 per 10 000, and 61.19 per 10 000, respectively, all of which were higher than those in passive surveillance (18.49 per 10 000, 0.50 per 10 000, and 1.50 per 10 000), with P values < 0.05. General reactions were mainly characterized by fever, local redness, and local induration. Abnormal reactions included angioedema and allergic rash. Coincidental cases were mainly infections. No severe adverse reactions occurred. Conclusion The large-scale vaccination of PCV13-TT/DT after its launch has good safety, and continuous strengthening of vaccine safety monitoring is needed.

Objective: To investigate the prevalence and influencing factors of the co-occurrence of elevated blood pressure and depressive symptoms among junior and senior high school students in Anhui Province, so as to provide evidence for comprehensive interventions on physical and mental health among adolescents. Methods: From September to December 2024, a multi stage random cluster sampling method was used to select 103 225 junior and senior high school students from 16 prefecture level cities in Anhui Province. Data were collected through questionnaire surveys and physical measurements. Elevated blood pressure was determined according to the Reference of Screening for Elevated Blood Pressure among Children and Adolescents Aged 7-18 Years. Depressive symptoms among middle school students were assessed using the Center for Epidemiologic Studies Depression Scale (CES-D). Chi-square test, Chi-square test for trend, and multivariate Logistic regression model were used to analyze the risk factors for the co-occurrence of elevated blood pressure and depressive symptoms. Results: The detection rate of elevated blood pressure was 15.22%, the detection rate of depressive symptoms was 18.56%, and the co-occurrence rate of the two conditions was 2.67% among junior and senior high school students. Multivariate Logistic regression analysis showed that after controlling for gender, school stage, household registration, and overweight and obesity status,compared with those who don t drink sugary drink and eat fried food, and get enough sleep, sugar sweetened beverage intake <1 and ≥1 time/d( OR =1.28,1.61), fried food consumption ≥1 time/d( OR =1.37), and insufficient sleep ( OR =1.54) were all associated with an increased risk of the co-occurrence of elevated blood pressure and depressive symptoms(all P <0.05). Daily fresh vegetable intake ≥1 time/d( OR =0.78) and fresh fruit intake ≥1 time/d( OR =0.85) were both associated with a decreased risk of the co-occurrence(both P <0.05). Compared with students who did not eat breakfast, students who ate breakfast sometimes and every day ( OR =0.62,0.36) had a lower co-occurrence risk(both P < 0.05). Junior and senior high school students with daily outdoor activity duration≥1 h ( OR =0.81) had a lower risk of the co-occurrence of elevated blood pressure and depressive symptoms ( P <0.05). Conclusions Sugar sweetened beverage drink and fried food consumption, inadequate consumption of fresh vegetables, fruits and breakfast, lack of outdoor activity, and insufficient sleep are risk factors for the co-occurrence of elevated blood pressure and depressive symptoms among junior and senior high school students in Anhui Province. It is necessary to establish school health promotion strategies integrating nutrition, exercise and sleep management as intervention targets to reduce the co-occurrence risk of elevated blood pressure and depressive symptoms among junior and senior high school students.

With the widespread application of chemotherapy, immunotherapy, and targeted therapy, cardiotoxicity associated with anti-tumor treatment has gained increasing attention. Drug-induced cardiac injury can significantly impact patients’ quality of life and may even limit the overall efficacy of anti-tumor therapy. The underlying mechanisms include oxidative stress, inflammatory responses, mitochondrial dysfunction, apoptosis, and immune dysregulation. Owing to multitarget effects, low toxicity, and holistic regulatory properties, Chinese traditional medicines have demonstrated considerable potential in cardioprotection. This review summarizes the principal mechanisms of drug-induced myocardial injury related to anti-tumor therapy and highlights recent advances in the prevention and treatment of cardiotoxicity using Chinese medical formulae, such as compound danshen dripping pills, nuanxinkang, qili qiangxin capsules, and shengmai powder, as well as their bioactive constituents. The cardioprotective effects of these agents are discussed in terms of their antioxidative, anti-inflammatory, immunomodulatory, and mitochondrial-protective actions. Furthermore, it highlights certain traditional medicines that exhibit unique advantages in synergistic cardioprotective and anti-tumor therapy. Future efforts should focus on well-designed, systematic clinical studies to facilitate the translational application of integrated Chinese and Western medicine in cardio-oncology.

Aging is an inevitable, physiological process of the human body, leading to deterioration in bodily function and increased susceptibility to various diseases. Effective endogenous therapeutic strategies for anti-aging and related diseases remain limited. Exercise confers multifaceted benefits to physical health by augmenting osteogenic and myogenic processes, enhancing cardiovascular and nervous system function, and attenuating chronic inflammation. Angiogenesis and lymphangiogenesis play pivotal roles in anti-aging, tissue repair, and immune response modulation, underscoring their potential as therapeutic targets for age-related diseases. Modulating angiogenic and lymphangiogenic pathways may provide a promising strategy for mitigating vascular decline and immune system dysfunction associated with aging. Exercise-induced endogenous angiogenesis and lymphangiogenesis can exert beneficial effects on physiological function, thereby representing a potential therapeutic paradigm for combating age-related decline and diseases. This review offers a thorough summary of the present knowledge regarding angiogenesis and lymphangiogenesis induced by exercise, encompassing the underlying mechanisms and the effects in different organs. In addition, it explores the potential of physical activity as a non-pharmacological intervention for anti-aging strategies and disease management, offering novel insights into the intersection of physical activity, aging, and disease progression.

Objective: To analyze the association of participation in non-sports extracurricular tutoring classes with the prevalence of screening myopia, axial length (AL) and axial length to corneal radius ratio (AL/CR) among primary school students, so as to provide evidences for formulating myopia prevention and control policies. Methods: In December 2024, combination of convenience and cluster sampling method was used to select 2 273 students from two primary schools in Hefei City, Anhui Province. Ophthalmic examinations and questionnaire surveys were conducted to obtain information on myopia, AL, AL/CR and participation in various types of extracurricular tutoring. A binary Logistic regression model was used to analyze the association between non-sports tutoring and screening myopia, and multiple linear regression models were used to examine the associations between non-sports tutoring and AL and AL/CR. Results: Among the surveyed students, the participation rate in non-sports extracurricular tutoring classes was 64.9% , and the overall prevalence of screening myopia was 39.1%. The average AL and AL/CR were (23.60± 1.01 ) mm and (3.00±0.12), respectively. Univariate analysis showed that students who attended non-sports, music, or academic tutoring classes for ≥2 h per week had higher risks of screening myopia and greater AL/CR values than non-participants (screening myopia: OR =1.38, 1.82, 1.55; AL/CR: β =0.01, 0.03, 0.03; all P <0.05). After adjusting for sex, grade, and participation in sports tutoring, multivariate analysis indicated that participation in non-sports and musical instrument tutoring classes for ≥2 h per week remained significantly associated with higher risks of screening myopia ( OR =1.26, 1.49, both P <0.05). Multiple linear regression showed that participation in musical instrument tutoring for ≥2 h per week was positively correlated with AL ( β=0.14, P < 0.05). Conclusions Participation in non-sports extracurricular tutoring is common among primary school students. Attending non-sports tutoring classes for ≥2 h per week increases the risk of screening myopia.

Objective To understand the epidemic characteristics and genotype distribution of acute hepatitis B in Tianjin, and to find out the relationship between genotype and epidemic characteristics. Methods The information of acute hepatitis B cases with a local address in Tianjin was collected through the National Infectious Disease Surveillance System in Tianjin from 2018 to 2022. The patient outcomes were followed up through hospital system records and telephone survey, and hepatitis B virus (HBV) genotypes were detected by fluorescent PCR. Results From 2018 to 2022, there were 387 cases of acute hepatitis B with local address reported in Tianjin, with an average annual reported incidence rate of 0.52/100 000, showing a downward trend in general (χ²=28.553，P<0.001). The reported male to female incidence ratio was 1.68. The age distribution was mainly concentrated in the 30-65 age group, with the highest incidence rate (1.22/100 000) reported in the 35-39 age group. 72.87% of cases showed negative HBsAg after 6 months of follow-up following diagnosis. The proportion of cadres and staff who turned negative (92.16%) was significantly higher than that of those who did not turn negative (0%). The median ALT (1508.00 U/L) in the turning negative group was significantly higher than that in the non-turning negative group (976.00 U/L). Among 315 cases with successful genotyping, genotype C accounted for 81.27%, and genotype B accounted for 14.92%, with 47 cases. The median ALT of genotype B patients with acute hepatitis B (1585.00 U/L) was significantly higher than that of genotype C patients (988.00 U/L). Conclusion The reported incidence rate of acute hepatitis B in Tianjin is relatively low, and shows a downward trend. Young and middle-aged men are prone to infect HBV. Genotype C is the main genotype, and genotype B HBV causes more serious liver damage in patients with acute hepatitis B.

Objective:To evaluate the clinical outcomes of endoscopic-assisted polyether ether ketone (PEEK) patient-specific implant (PSI) revision for over-resected mandibles caused by the mandibular angle osteotomy.Methods:A retrospective analysis was conducted on 24 patients [8 males, 16 females, aged 19-57 (32.5±9.5) years] with 39 over-resected mandibles that underwent PEEK-PSI mandibular angle revision surgery at the Affiliated Friendship Plastic Surgery Hospital of Nanjing Medical University from January 2019 to December 2023. Preoperative cone-beam computed tomography (CBCT) data were used to design and fabricate customized PEEK PSIs based on individual anatomical requirements. An intraoral incision approach with endoscopic assistance was employed to meticulously dissect soft tissue attachment around the angle region, followed by the implantation of a customized PEEK PSI. Postoperative CBCT scans were performed for 3D reconstruction, with root mean square error (RMSE) and maximum deviation (MaxD) as accuracy metrics. Patients′ satisfaction was assessed preoperatively and ≥6 months postoperatively using the face questionnaire (FACE-Q) scores, which included overall facial appearance, lower face and jawline, appearance distress, psychological health and social function.Results:All 24 patients achieved satisfactory recovery with primary healing of intraoral incisions. No complications such as infection, nerve injury, or implant rejection occurred during follow-up period. Patients′ facial appearance and jaw line contouring were significantly improved. Fine anatomical fitting between PEEK-PSI and defect areas was observed: RMSE ranged from 0.117 to 0.315 mm, and MaxD was (5.485±1.300) mm. FACE-Q scores demonstrated significant improvements after surgery in overall facial appearance [(49.8±5.4) vs (65.0±5.3) scores], lower face and jawline [(42.5±5.3) vs (56.1±4.6) scores], appearance distress [(60.0±6.9) vs (70.6±6.5) scores], psychological health [(62.0±5.0) vs (70.8±5.3) scores], and social function [(60.3±4.3) vs (69.3±5.8) scores] (all P<0.001). Conclusion:Endoscopic-assisted PEEK-PSI revision for over-resected mandibles following mandibular angle osteotomy exhibits high surgical precision and safety, effectively restoring mandibular contour and significantly enhancing patients′ satisfaction.

Objective:To explore the effect of target-oriented management of regional cerebral oxygen saturation (rScO 2) monitoring on gastrointestinal surgery in elderly patients with fragile brain function. Methods:A total of 60 elderly patients with fragile brain functional surgery admitted to Changzhi People′s Hospital from January 2022 to December 2022 were divided into the study group and the conventional group by the random number table method, each group with 30 cases, rScO 2 monitoring target-oriented management and conventional anesthesia monitoring management were given respectively during the operation. The levels of mean arterial pressure (MAP), blood gas analysis and cerebral oxygen metabolism indexes were compared between the two groups at different time points. Postoperative recovery related indexes and the incidence of postoperative delirium (POD) and postoperative cognitive dysfunction (POCD) were recorded and compared between the two groups. Results:The level of MAP at 30 min after anesthesia in the study group was significantly higher than that in the conventional group: (90.50 ± 6.03) mmHg vs. (82.05 ± 6.10) mmHg, 1 mmHg = 0.133 kPa, there was statistical difference ( P<0.05). The levels of blood lactic acid (Lac) and blood glucose (GLU) at 60 min and immediately after surgery in the study group were lower than those in the conventional group: (1.45 ± 0.48) mmol/L vs. (1.90 ± 0.51) mmol/L, (1.34 ± 0.42) mmol/L vs. (1.65 ± 0.46) mmol/L; (7.17 ± 0.90) mmol/L vs. (7.62 ± 0.76) mmol/L, (6.70 ± 0.87) mmol/L vs. (7.11 ± 0.67) mmol/L, there were statistical differences ( P<0.05). The jugular veinoxygen content (CjvO 2) at 60 min after operation in the study group was higher than that in the conventional group: (98.16 ± 20.34) ml/L vs. (85.32 ± 18.54) ml/L; cerebral extraction rate of oxygen (CERO 2) and the internal jugular veno-arterial blood lactic acid difference (Djv-aLac) were lower than those in the conventional group: (33.00 ± 7.86)% vs. (40.52 ± 9.05)%, (0.15 ± 0.05) mmol/L vs. (0.21 ± 0.07) mmol/L, there were statistical differences ( P<0.05). The recovery time, tracheal extubation time and hospital stay in the study group were lower than those in the conventional group: (12.25 ± 2.00) min vs. (15.00 ± 3.14) min, (14.00 ± 2.34) min vs. (20.12 ± 4.37) min, (9.00 ± 1.13) d vs. (9.65 ± 1.25) d, there were statistical differences ( P<0.05). The POD incidence in the study group was lower than that in the conventional group: 6.67%(2/30) vs. 26.67%(8/30), there was statistical difference ( χ2 = 4.32, P<0.05). The incidence of POCD within 1 week after surgery had no statistical difference between the two groups ( P>0.05). Conclusions:rScO 2 monitoring and target-oriented management can better maintain the stability of hemodynamics and cerebral oxygen metabolism in elderly patients with fragile brain function, and can improve blood gas analysis index, reduce the occurrence of postoperative POD and other cognitive abnormalities, which is beneficial to their postoperative outcome.

Objective:To explore the effect of transcranial direct current stimulation (tDCS) on dysphagia in hemispheric stroke patients.Methods:Sixty-two hemispheric stroke patients with dysphagia were randomized into an ipsilateral group, a contralateral group and a bilateral group with 20 in each group. The ipsilateral and contralateral groups received tDCS over their ipsilesional and contralesional hemispheres, respectively, while in the bilateral group it was over both hemispheres. That was followed by conventional swallowing therapy. Before and after 2 weeks of the treatment, swallowing function was assessed using the modified Mann Assessment of Swallowing Ability (MMASA) and a Swallow Severity scale (SSS). Linear regressions were evaluated to highlight the factors most influencing recovery from post-stroke hemispheric dysphagia.Results:After the treatments, the average MMASA and SSS scores had increased significantly in all three groups. There was no significant difference in the average post-treatment MMASA and SSS scores between the ipsilateral and contralateral groups, but the bilateral group showed significantly better average post-treatment MMASA and SSS scores compared to the other two groups. Linear regression analysis confirmed that the tDCS protocol (group allocation) was a significant predictor of recovery.Conclusion:Bilateral tDCS can effectively promote the recovery of swallowing function after a hemispheric stroke. It demonstrates greater therapeutic benefits than unilateral tDCS.

Objective:To investigate the role of endoplasmic reticulum stress(ERS)-related long non-coding RNA(lnc RNA)Gm9795 in the progression of hepatocellular carcinoma(HCC).Methods:This retrospective cohort study included 80 HCC patients who underwent routine surgical procedures at Nanjing Jiangning Hospital from 2014 to 2020.Colecting clinical datas from all patients and using real-time fluorescence quantitative PCR to detect the expression level of Gm9795 in 80 patients'cancer and adjacent tissues,as well as in HCC cells(HepG2,Hep3B,HCCLM3,and Huh7).The correlation between Gm9795 expression and overall survival time and recurrence free survival time of HCC patients was analysised.Constructing HCCLM3 cells overexpressing Gm9795 through lentiviral infection,and constructing Huh7 cells silencing Gm9795 expression through liposome transfection.The proliferation ability of cells was evaluated using CCK-8 assay and colony formation assay,while the migration and invasion ability of cells were detected using Transwell assay.Identification of Gm9795 specific binding protein by mass spectrometry(MS).The effect of overexpressing or silencing Gm9795 expression on the expression of C/EBP homologous protein(CHOP)gene was detected by Western blotting.The CHOP gene was simultaneously transferred into HCCLM3 cells overexpressing Gm9795,and the effects of up-regulating CHOP expression level on the proliferation,migration,and invasion of HCCLM3 cells were evaluated using CCK-8 assay,colony formation assay,and Transwell assay.Results:Compared with adjacent tissues,the expression level of Gm9795 was significantly up-regulated in HCC tissues(P<0.001).The expression levels of Gm9795 in all HCC cells were significantly higher than in normal hepatocytes LO2(all P<0.05).Higher expression levels of Gm9795 were associated with aggressive clinical pathological features,including tumor size,multiple tumors,Barcelona Clinic Liver Cancer(BCLC)staging,and portal vein tumor thrombus(all P<0.05).The results of multivariate analysis showed that high expression level of Gm9795 was an independent prognostic factor for overall survival and recurrence free survival in HCC patients(both P<0.05).The higher expression of Gm9795 was significantly correlated with shorter overall survival and recurrence free survival in the cohort(both P<0.01).Compared with the Vector group,the proliferation,migration,and invasion of HCCLM3 cells were significantly enhanced in the Gm9795 overexpression group(all P<0.01);Compared with the siNC group,the proliferation,migration,and invasion of Huh7 cells were significantly reduced in the siGm9795-1 and siGm9795-2 groups(all P<0.01).CHOP was identified as a Gm9795 specific binding protein by MS.Compared with the Gm9795+Vector group,the Gm9795+CHOP group showed significant reductions in proliferation,migration,and invasion of HCCLM3 cells(all P<0.01).Conclusions:Gm9795 is up-regulated in HCC tissues,and the high expression of Gm9795 is an independent prognostic factor for the overall survival of HCC patients.Gm9795 promotes the proliferation and invasion of HCC cells in vitro,and its mechanism may be related to the inhibition of ERS mediated by CHOP signaling pathway.
