Objective To investigate the existing nuclear radiation health emergency response capacity of local health systems at nuclear power plant sites in Guangdong Province. Methods The health administrative departments of all nuclear power plants sites in Guangdong Province, along with radiation health protection institutions, designated nuclear radiation treatment hospitals, and township health centers, were selected as the study subjects using the purposive sampling method. A series of standardized questionnaires on the capacities for nuclear radiation health emergency response, developed uniformly by the National Institute for Radiological Protection, Chinese Center for Disease Control and Prevention, were adopted to separately investigate the capacities for nuclear radiation health emergency response in the study subjects. Results There were 13 health administration departments, 15 radiological health protection institutions, 18 designated hospitals for nuclear radiation medical response, and 18 township health centers located in the nuclear power plants sites in Guangdong Province. Among the 13 health administration departments, the Health Commission of Guangdong Province met all 15 criteria for nuclear radiation health emergency response capacities. All six prefecture-level health administrative departments possessed more than 10 capacities for nuclear radiation health emergency response, while only one of the six county-level departments had more than 10 such capacities. Among radiation health protection institutions, the provincial-level institution possessed all 18 capacity for nuclear radiation health emergency response; of the six prefectural-level institutions, only four had more than 10 capacities; none of the eight county-level institutions or 18 township health centers possessed more than 10 capacities. Among designated nuclear radiation treatment hospitals, provincial-level institution met all 32 capacities for nuclear radiation health emergency response; of the eight prefecture‑level hospitals, only four meet more than ten such capacities; and of the nine county‑level hospitals and 18 township health centers, none possess more than 10 capacities. Conclusion Provincial- and prefectural-level nuclear radiation emergency capacity in Guangdong Province is adequate, whereas county-level and township health centers have obvious weaknesses in organizational structure, personnel training, equipment reserves, funding, and technical reserves; emergency response capacity needs urgent enhancement.

Objective To analyze the current status of nuclear radiation health emergency response capacity in areas of the nuclear power plants in Guangdong Province, and to formulate a construction plan for municipal-level nuclear radiation health emergency response teams. Methods Provincial-, municipal-, and county-level administrative regions in the nuclear power plant host areas of Guangdong Province were selected as the study subjects. A series of questionnaires designed by the National Institute for Radiological Protection, Chinese Center for Disease Control and Prevention, were used to assess the capacity of nuclear radiation health emergency response. Based on the findings, a construction plan for municipal-level nuclear radiation health emergency response teams was formulated. Results A total of 13 administrative regions which host nuclear power plants were involved, including one provincial-level, six municipal-level, and six county-level regions. The availability rates of 31 capacity indicators of nuclear radiation health emergency response among 13 administrative regions ranged from 15% to 100%, with an average of 51%. Provincial-level capacity of nuclear radiation health emergency response was relatively well established, county-level radiation monitoring and protection capacity was nearly absent, municipal-level regions possessed basic capacity, but with obvious regional disparities and a general lack of specialized facilities and materials required for the treatment of nuclear radiation injuries, making them the key level for improvement in nuclear radiation health emergency response. The Construction Plan for Municipal-Level Nuclear Radiation Health Emergency Response Teams specifies that the total number of team members should be no fewer than 30 to ensure rapid response and immediate arrival at the scene. The List of Key Professional Equipment proposes the prioritized allocation of five categories of equipment: personal basic equipment, contamination detection and classification equipment, decontamination equipment, medical treatment equipment, and command and logistical support equipment. Conclusion Nuclear radiation health emergency response capacity in Guangdong Province requires further improvement, particularly in standardized development of municipal-level nuclear radiation health emergency response teams. The Construction Plan for Municipal-Level Nuclear Radiation Health Emergency Response Teams defines capacity requirements and provides a list of essential equipment, offering a practical reference for other regions.

Objective:
To evaluate the cost-utility of different pulmonary tuberculosis screening programs using a decision tree-Markov model, so as to provide the theoretical basis for pulmonary tuberculosis prevention and control strategies among elderly patients with diabetes mellitus in Nanjing.
Methods:
The baseline data for this study were obtained from the National Basic Public Health Service Project Management Information Platform. The baseline cohort consisted of patients with diabetes mellitus aged ≥65 years with no history of active tuberculosis and/or currently taking anti-tuberculosis medications. Based on symptoms and chest X-ray findings, three different screening protocols for pulmonary tuberculosis were developed: a passive screening protocol for patients presenting with symptoms, a two-step screening protocol involving X-ray examination following positive symptoms, and a combined screening protocol involving X-ray examination following symptom-based screening; Treeage Pro 2022 software was used to construct a decision tree-Markov model simulating the incidence and progression of pulmonary tuberculosis in elderly patients with diabetes mellitus. The incremental cost-utility ratio (ICUR) of the three screening strategies was calculated and compared in terms of yuan per quality-adjusted life year (QALY), and sensitivity analyses were performed on the model.
Results:
In a simulated screening of 100 000 elderly patients with diabetes mellitus, the number of pulmonary tuberculosis cases detected by passive screening, two-step screening, and combined screening were 3 116, 4 656, and 5 086, with corresponding detection rates of 3.12%, 4.66%, and 5.09%, respectively. The differences were statistically significant (P<0.05). The number of pulmonary tuberculosis-related deaths were 513, 160, and 82, with corresponding mortality of 16.46%, 3.44%, and 1.61%, respectively, and the differences were also statistically significant (P<0.05). Compared with the passive screening strategy, the ICURs for the two-step screening and combined screening strategies were 37 546.89 yuan/quality-adjusted life-year (QALY) and 77 827.52 yuan/QALY, respectively, both of which demonstrated cost utility. Compared with the two-step screening strategy, the ICUR for the combined screening strategy was 197 395.55 yuan/QALY, demonstrating cost utility. Sensitivity analysis indicated that the results were generally robust; when the willingness-to-pay threshold was set at 241 041 yuan/QALY, the combined screening strategy had the highest probability of being cost-utility effective, at 63.70%.
Conclusions
Theoretically, the combined screening protocol for pulmonary tuberculosis, consisting of symptom screening followed by X-ray examination, is more cost-utility effective among elderly patients with diabetes mellitus in Nanjing City. Therefore, its implementation is recommended for this population.

Objective:To observe the pregnancy outcomes of patients with unexplained recurrent spontaneous abortion (URSA) after interventional treatment or expectant treatment.Methods:This prospective study followed up 398 patients with recurrent spontaneous abortion from March 2017 to September 2022 in seven hospitals. Among them, 267 patients were diagnosed with URSA, including 124 patients who were initially diagnosed in the interventional treatment hospital and 143 patients who were initially diagnosed in the expectant treatment hospital. All URSA patients were followed up for 33 months. Ongoing pregnancy rates were observed as main outcome indicators.Results:A total of 127 patients became pregnant, and 107 of them had sustained pregnancies, the ongoing pregnancy rate was 84.25% (107/127). The ongoing pregnancy rate was 86.11% (31/36) in the interventional treatment group and 83.52% (76/91) in the expectant treatment group, with no significant difference ( P>0.05). During the follow-up, the ongoing pregnancy rates in the interventional treatment hospital and the expectant treatment hospital were 75.71% (53/70) and 94.74% (54/57), respectively, with a significant difference ( P<0.05). The ongoing pregnancy rate after interventional treatment in the interventional treatment hospital was 82.76% (24/29), which was similar to the 94.00% (47/50) after expectant treatment in the expectant treatment hospital ( P>0.05). Conclusion:The ongoing pregnancy rate of interventional treatment for URSA patients has not been significantly improved, suggesting that it may not be necessary to carry out this treatment.

Objective:To assess the preliminary efficacy and safety of modified Société Internationale d′Oncologie Pédiatrique Epithelial Liver Tumor Study Group (SIOPEL)-4 protocol for pediatric hepatoblastoma (HB) with lung metastases.Methods:This prospective cohort study enrolled 27 newly diagnosed pediatric HB with lung metastases who received the modified SIOPEL-4 protocol at Shanghai Children′s Medical Center, Shanghai Jiao Tong University School of Medicine, and Shanghai Children′s Hospital between January 2020 to December 2023. Clinical characteristics, lung response rates to induction chemotherapy, treatment outcomes, prognostic factors and sever chemotherapy toxicities at different stages were analyzed. Survival analysis was performed by Kaplan-Meier method. Univariate prognostic analysis was conducted by Log-Rank test.Results:Of the 27 patients, there were 17 males and 10 females, with the age of 21 (15, 33) months. During the follow-up of 31 (12, 45) months for 17 continuous complete remission patients, 4 cases disease progression (2 cases death) and 6 cases relapse were observed. The 2-year event free survival (EFS) and overall survival (OS) rate was (58±11)% and (89±7)%, respectively. All the 27 patients had response to block 1-3 induction chemotherapy (cisplatin+doxorubicin), with 14 cases (52%) achieving complete response and 13 cases (48%) achieving partial response of lung metastatic lesions, the 2-year EFS rate was (81±12)% and (34±14)%, respectively ( χ 2=6.76, P=0.009), the 2-year OS rate was 100% and (79±13)%, respectively ( χ2=2.12, P=0.145). Patients with caudate lobe tumors or ≥10 pulmonary metastatic nodules had significantly lower EFS rates ( χ2=5.36, 7.84, P=0.021, 0.005, respectively). The incidence of grade 3/4 neutropenia after block 1-3 induction chemotherapy, CD (carboplatin+doxorubicin), and VI (vincristine+irinotecan) consolidation chemotherapy was 90% (73/81), 75% (58/77), and 31% (11/35), respectively. The incidence of grade 3/4 thrombocytopenia was 77% (62/81), 69% (53/77), and 14% (5/35), respectively. The incidence of grade 3/4 infections was 64% (52/81), 25% (19/77), and 20% (7/35), respectively. The differences between the groups were statistically significant ( χ2=43.51, 42.69, 33.00, all P<0.001). Two patients (10%) of the 20 evaluable patients for ototoxicity occurred grade 3 and higher hearing impairment, with 1 patient requiring a hearing aid. Conclusions:The modified SIOPEL-4 regimen shows good preliminary efficacy and safety in treating pediatric HB with lung metastases. The prognosis for patients with residual lesions in the lungs after induction chemotherapy needs to be improved. Attention should be given to the ototoxicity induced by high-dose cisplatin chemotherapy.

Objective:To analyze the iodine nutrition status and its related factors among adults aged 18 years and above in Zhejiang Province in 2022.Methods:A multistage stratified sampling method was used to select 4 320 adults aged 18 years and above from 16 on-site survey sites in Zhejiang Province for the study. A questionnaire was used to investigate the general demographic information and personal dietary characteristics of the study participants. Household edible salt and urine samples were collected to detect salt iodine content and urinary iodine level by using direct titration and cerium arsenate-catalyzed spectrophotometry, respectively, to evaluate the iodine nutritional status according to the standard. The multiple-ordered logistic regression model was used to analyze the factors influencing the urinary iodine concentration.Results:The age of the 4 320 study participants was (51.19±15.33) years, with males accounting for 44.44% (1 920). About 40.16% of adults (1 735) were from coastal areas and 56.37% (2 435) from urban areas. The salt iodine content, M ( Q1, Q3), of the 4 320 household edible salt samples was 21.10 (0.00, 24.16) mg/kg, including 1 662 non-iodized salt samples, 182 unqualified iodized salt samples and 2 476 qualified iodized salt samples. The rate of iodized salt coverage was 61.53%, and the rate of qualified iodized salt consumption was 57.31%. There was a statistically significant difference in the proportion of qualified iodized salt in adult households among different regions ( P<0.001), with the proportion of non-iodized salt gradually decreasing from coastal to inland areas ( χ 2trend=618.458, P<0.001). The urinary iodine concentration M ( Q1, Q3) was 137.60 (86.85, 210.60) μg/L in 4 320 adult urine samples, with the urinary iodine levels of<100, 100-199, 200-299, and≥300 μg/L accounting for 31.64% (1 367), 40.56% (1 752), 17.66% (763), and 10.14% (438), respectively. There was a nonlinear positive correlation between household salt iodine content and urinary iodine level in adults aged 18 years and above by using the χ 2 test for trend ( χ 2regression=231.10, P<0.001 and χ 2skew=28.81, P<0.001). Urinary iodine concentrations were higher in men than in women ( P=0.029) and higher in adults in rural areas than in urban areas ( P<0.001). There were statistically significant differences in the distribution of iodine nutritional status among adults of different ages, regions, and urban and rural areas (all P<0.001). The proportion of those with urinary iodine levels<100 μg/L gradually increased with age ( χ 2trend=37.493, P<0.001), and gradually decreased from coastal areas to inland areas ( χ 2trend=71.381, P<0.001). The results of the multiple-ordered logistic regression model analysis showed that compared with adults aged 18 to 44 years and male adults, those aged 45 to 59 years and female adults had lower urinary iodine levels, with OR (95% CI) of 0.75 (0.68-0.83) and 0.85 (0.76-0.95), respectively. Compared with adults in coastal and urban adults, those in sub-coastal, inland and rural adults had higher levels of urinary iodine, with OR (95% CI) of 1.89 (1.63-2.19), 2.02 (1.72-2.37) and 1.46 (1.28-1.66), respectively. Conclusion:The overall iodine nutrition level of adults aged 18 years and above in Zhejiang Province in 2022 is generally appropriate. However, there is a potential risk of iodine deficiency among adults in coastal areas.

Objective To investigate the predictive value of preoperative systemic inflammatory response index(SIRI)combined with clinicopathological parameters for postoperative recurrence in cervical cancer and to construct a prognostic model in order to optimize recurrence risk assessment.Methods Patients with cervical cancer who underwent standard surgical treatment at the First Affiliated Hospital of Chongqing Medical University(training cohort,n=996)and Chongqing Maternal and Child Health Hospital(validation cohort,n=496)between January 2017 and January 2022 were retrospectively enrolled based on our strict inclusion and exclusion criteria.Univariate and multivariate Cox regression analyses were performed to identify independent prognostic factors for recurrence-free survival(RFS),and then a nomogram was constructed.Receiver operating characteristic(ROC)curve was plotted to assess the predictive performance of the model,and the area under the curve(AUC)and calibration curve were employed to evaluate the model.Kaplan-Meier survival analysis was performed to determine the clinical application.Results Cox regression analysis demonstrated that International Federation of Gynecology and Obstetrics(FIGO)stage(P<0.001),tumor size(P<0.001),pathological type(P<0.001),tumor grade(P=0.007),parametrial invasion(P<0.001),depth of myometrial invasion(P=0.019),lymphovascular space invasion(P=0.019),vaginal margin involvement(P=0.010),adjuvant therapy(P=0.012),and SIRI(P<0.001)were independent prognostic factors for RFS.Our nomogram model based on above prognostic factors exhibited superior predictive performance for 1-,3-,and 5-year RFS,with a significantly higher AUC value(0.886)than those of single-parameter models.Conclusion Our nomogram model demonstrated good accuracy in predicting RFS in cervical cancer patients,providing a potential tool for personalized clinical decision-making in recurrence risk management.
9.A bibliometric analysis of non-coding RNA and mesenchymal stem cell research
Chinese Journal of Tissue Engineering Research 2025;29(1):87-94
BACKGROUND:Non-coding RNA,as a class of RNA molecules that do not encode proteins,plays a crucial role in cellular regulation.Simultaneously,mesenchymal stem cells possess multipotent differentiation capabilities,making them vital for tissue repair and regeneration.In recent years,researchers have extensively explored the role of non-coding RNA in regulating the functions of mesenchymal stem cells. OBJECTIVE:To systematically understand the trends and key areas of research related to non-coding RNA and mesenchymal stem cells through bibliometric analysis. METHODS:Literature data on non-coding RNA and mesenchymal stem cell-related research were retrieved from the Science Citation Index Expanded in the Web of Science Core Collection from 1990 to the present.The literature data were analyzed using bibliometric tools such as VOSviewer and CiteSpace,focusing on publication output,clustering,citation frequency,burstiness,and intermediary centrality with respect to years,countries or regions,research institutions,cited references,and keywords.This analysis aimed to reveal the knowledge base and emerging hotspots in the research field. RESULTS AND CONCLUSION:(1)This study included a total of 5 348 articles for analysis,showing a significant growth trend in relevant literature from 1997 to 2021.Although there was a slight decrease in 2022,the publication output remained at a high level.China dominated the research in this field,with Shanghai Jiao Tong University being the most active contributor.(2)Analysis of cited references revealed that highly bursty,intermediary,and cited articles were mainly related to topics such as microRNA,extracellular vesicles,and bone metabolism.These articles constitute an important knowledge base for research on non-coding RNA and mesenchymal stem cells.(3)Burstiness analysis of keywords identified persistent bursts in keywords such as exosomes,circular RNA,extracellular vesicles,and injury.(4)Cluster evolution analysis of keywords with continuous growth in publication output included clusters related to tumor microenvironment,osteoarthritis,oxidative stress,and extracellular vesicles.These keywords reflect the current and future research hotspots in the field.(5)The findings of this study not only illustrate the research trends in the field of non-coding RNA and mesenchymal stem cells but also provide potential directions and insights for researchers.

Objective:To investigate the clinical diagnosis and treatment of IgG4-related disease(IgG4-RD) primarily involving the nasal cavity and skull base. Methods:A retrospective analysis was conducted on the clinical data of 8 patients with IgG4-RD primarily involving the nasal cavity and skull base who visited the Nasal and Skull Base Surgery Department at Xiangya Hospital from October 2017 to January 2024. The cohort comprised 4 males and 4 females, aged 8 to 69 years. Clinical data, laboratory examination results, imaging findings, histopathological results, and treatment plans were collected. The clinical manifestations, diagnosis, treatment and follow-up results of IgG4-RD primarily involving nasal cavity and skull base were summarized and previous literature were also reviewed. Results:The initial symptoms in the 8 patients included nasal congestion, headache, sensory function decline, and facial deformities. Three patients also had parotid and pulmonary involvement. Among the 8 patients, 4 underwent partial surgical resection combined with glucocorticoid therapy; 1 underwent partial surgical resection combined with glucocorticoid and immunosuppressant therapy; 1 received glucocorticoid therapy alone; and 2 received glucocorticoid combined with immunosuppressant therapy. Follow-up was conducted one month after treatment, lasting from 5 to 79 months. During the follow-up period, recurrence was observed in 1 patient treated with glucocorticoid combined with immunosuppressants and in 1 patient treated with glucocorticoid alone, while the other 6 patients achieved significant remission. Conclusion:The diagnosis of nasal cavity and skull base IgG4-RD requires the combination of histopathology, laboratory tests, and imaging results. Treatment primarily includes glucocorticoids or combined immunosuppressants. For patients with significant compression symptoms, sensory function impairment, or facial deformities, surgical resection is an important treatment option. Given the high risk of recurrence, early intervention, active treatment, and long-term follow-up are crucial.
