Implementation science (IS) aims to systematically analyze and address the real-world gaps from evidence to practice and the influencing factors of the context. It is necessary to carry out qualitative research to gather relevant implementation outcomes. Nevertheless, traditional qualitative analysis has issues such as consuming a great deal of time and energy, and it is unable to promptly provide the crucial data required for implementation science research. The Rapid Qualitative Analysis (RQA) method, through semi-structured interviews and the adoption of techniques such as immediate data condensation and matrix analysis, can effectively shorten the cycle of qualitative data collection and data processing. RQA can promptly identify social determinants of health such as structural barriers, facilitators, and the behavioral characteristics of target groups. It provides a real-time basis for public health decision-making, the interpretation of complex social phenomena, and the process and effectiveness evaluation of research projects. Although RQA is difficult to conduct in-depth theoretical analysis based on grounded theory, its efficiency and flexibility make it the preferred tool for large-scale and time-sensitive research. Thus, it has been widely applied in implementation science research. This paper sorts out the core concepts and commonly used technical methods of RQA, as well as the differences between RQA and traditional qualitative analysis. It also explores the applications of RQA in intervention optimization, process evaluation, and implementation outcome evaluation. By integrating specific cases, this paper clarifies its application value in the field of implementation science. In the future, it is advisable to explore the integration of RQA with technologies such as artificial intelligence and big data, in order to bridge the gap between the transformation of scientific research achievements into practice. Under circumstances of limited resources or tight time constraints, RQA can be used to efficiently conduct implementation science research, providing convenient and scientific methodological and technical support for accelerating evidence-based practice.

Background Sunshine duration is closely associated with population mental health and emotional states, although its relationship with mental and behavioral disorders (MBD) remains insufficiently studied. Objective To analyze the effect of sunshine duration on hospital admissions for MBD in Zigong City, Sichuan Province. Methods Hospital admission records for MBD from 10 medical institutions, meteorological data, and ambient air pollutant concentrations were collected in Zigong City from January 1, 2019 to December 31, 2024. A distributed lag non-linear model (DLNM) was employed to calculate single-day and cumulative lag effects of different sunshine duration exposures—0 h (P₀, P₅, P₂₅), 6 h (P₇₅), and 10.4 h (P₉₅)—on hospitalization risks for MBD, stratified by diagnostic category, sex, and age groups. Results This study analyzed 36597 hospital admissions for MBD in Zigong City. The exposure-response curve for sunshine duration at lag 0 d exhibited an inverted N-shaped pattern, with minimum relative risk (RR) of hospitalizations observed at 14 h sunshine duration. The immediate effects of different levels of sunshine duration on the hospitalization risk for MBD, schizophrenia, schizotypal and delusional disorders (SSDD), and neurotic, stress-related and somatoform disorders (NSSD) were significant, with the cumulative effect peaking at lags 12–13 days. For extremely short sunshine duration 0 h, the maximum relative risk (RR) values (with 95% confidence intervals, 95%CI) of hospitalization risk were 1.209 (1.001, 1.459) at lag 1 d for SSDD patients and 1.398 (1.133, 1.724) at lag 0 d for NSSD patients, respectively. The cumulative effect on hospitalization risk induced by short sunshine duration 6 h was higher than that induced by extremely short sunshine duration 0 h and long sunshine duration 10.4 h. Among populations stratified by gender and age, male patients and those aged over 70 years had higher hospitalization risks. For short sunshine duration 6 h, the cumulative RR (CRR) value (95%CI) of hospitalization risk for male MBD patients was 3.373 (1.362, 8.358) at cumulative lag 0–12 d, which was higher than that for female patients [2.943 (1.471, 5.889) at cumulative lag 0–13 d]. The population aged over 70 years was more sensitive to single-day and cumulative lag effects on hospitalization risk than other age groups. For short sunshine duration 6 h, the RR and CRR values (95%CI) of single-day and cumulative lag effects on hospitalization risk were 1.336 (1.002, 1.783) at lag 0 day and 5.085 (1.680, 15.392) at cumulative lag 0–12 d, respectively. At lag 13 d, long sunshine duration 10.4 h exposure was associated with depression hospitalizations in patients <20 years with RR=1.127 (95%CI: 1.002, 1.270). Conclusion When the daily sunshine duration is less than 14 h, it will increase the hospitalization risk of MBD in the population to varying degrees, with both single-day and cumulative lag effects. It is recommended that the public, especially vulnerable groups such as people with MBD aged 70 years and above and those with depression under 20 years, strengthen health protection to reduce the health risks caused by changes in sunshine.

Objective To explore the correlation between the pathogenesis of toxins damaging liver collateral and the incidence of type 2 diabetes mellitus(T2DM)based on the theory of five circuits and six qi.Methods A total of 986 patients with T2DM treated in the Department of Endocrinology and Metabolism at the Affiliated Hospital of Changchun University of Chinese Medicine from February 2019 to October 2023 were selected as the study subjects.The influences of circuit and qi indicators in the theory of five circuits and six qi on the constitutional characteristics of T2DM patients and the role of pathogenesis of toxins damaging liver collateral in the incidence of T2DM were investigated.Results(1)The five-circuit and six-qi analysis showed that the yearly circuit and sitian/zaiquan conditions had no significant effect on the constitutional characteristics of patients with T2DM(P＞0.05).However,dominant circuit,guest circuit,dominant qi and guest qi significantly influenced the constitutional characteristics of patients with T2DM(P＜0.05).For the distribution of circuit-qi indicators at birth among the 986 patients,dominant circuit was predominated by the terminal circuit of taiyang cold-water,guest circuit was characterized by deficient wood circuit or excessive water circuit,dominant qi was predominated by yangming dry-metal,and guest qi was characterized by taiyin damp-earth.(2)The correlation between the pathogenesis of toxins damaging liver collateral and the incidence of T2DM through comparative analysis revealed that the conveying and dispersing function of the liver plays a leading role in maintaining the body's yin-yang balance and ensuring free movement of qi,indicating that the critical role of toxins damaging liver collateral is the key to the incidence of diabetes.Conclusion Circuit-qi indicators have a certain influence on the constitutional characteristics of T2DM patients.The circuit-qi features at birth of the individuals prone to T2DM are as follows:dominant circuit predominated by the terminal circuit of taiyang cold-water,guest circuit characterized by deficient wood circuit or excessive water circuit,dominant qi being yangming dry-metal,and guest qi being taiyin damp-earth.Pathogenesis of toxins damaging liver collateral is closely related to the incidence of T2DM.Therefore,in treatment,the regulatory role of the liver should be emphasized,and liver-soothing herbs should be used based on syndrome differentiation,aiming for holistic treatment of the physique and the spirit and enhancing the therapeutic efficacy.The exploration will provide a new perspective and approach for the treatment of T2DM.

Objective:To understand the prevalence and related factors of three common chronic diseases, hyperlipidemia, hypertension and diabetes in HIV-infected persons.Methods:As of December 2023, HIV-infected persons >15 years old who are receiving antiviral therapy (ART) and follow-up in Henan Province were selected as the study objects. Questionnaires, physical examinations, and blood samples were collected to collect demographic information, ART, body weight, blood lipids, blood pressure, and blood sugar of HIV-infected persons. The logistic regression model was used to analyze the related factors of hyperlipidemia, hypertension and diabetes.Results:Among 4 023 HIV-infected patients, the prevalence rates of hyperlipidemia, hypertension, and diabetes were 64.47% (2 594/4 023), 16.80% (676/4 023), and 10.54% (424/4 023), respectively. Multivariate analysis showed that hyperlipidemia was positively associated with ≥40 years of age, overweight and obesity, two nucleoside reverse transcriptase inhibitors (NRTIs) + proteasome inhibitors (PIs) regimen and two NRTIs+ integrase inhibitor regimen, and negatively associated with low body weight. Hypertension was positively correlated with the age group ≥40 years old, family history of cardiovascular and cerebrovascular diseases, overweight and obesity, ART time ≥0.5 years, and negatively correlated with low body weight. Diabetes was positively associated with age group ≥40 years, family history of cardiovascular and cerebrovascular disease, overweight and obesity, and negatively associated with the use of two NRTIs+PIs treatment regimens.Conclusions:In 2023, the prevalence of hyperlipidemia, hypertension, and diabetes among HIV-infected people in Henan Province was relatively high, and the risk of common chronic diseases among those ≥40 years old, overweight and obese, and those with a family history of cardiovascular and cerebrovascular diseases was also relatively high. It is recommended to strengthen the prevention and management of common chronic diseases among HIV-infected people.

Objective To investigate the correlation of serum levels of Spexin,FoxO1 and insulin resistance(IR)with prognosis in patients with gestational diabetes mellitus(GDM).Methods A total of 198 patients with GDM were prospectively selected as the GDM group,and 195 healthy pregnant women who underwent physical examinations during the same period were selected as the control group.The age at enrollment,gestational age,triglyceride(TG),pre-pregnancy body weight,fasting insulin(FINS),parity,fasting blood glucose(FBG),total cholesterol(TC)and homeostasis model assessment of insulin resistance index(HOMA-IR)of the subjects were collected.The serum levels of Spexin and FoxO1 in subjects were detected by enzyme-linked immunosorbent assay(ELISA).According to the pregnancy outcome,the GDM patients were divided into the adverse pregnancy outcome group(96 cases)and the good pregnancy outcome group(102 cases).The correlations between serum Spexin,FoxO1,and HOMA-IR in GDM patients were analyzed by Pearson's method.Logistic regression was used to analyze risk factors affecting the pregnancy outcome of GDM patients.The predictive value of serum Spexin and FoxO1 levels for the pregnancy outcome of GDM patients was analyzed by receiver operating characteristic(ROC)curve.Results The serum levels of FINS,TG,FBG,Spexin,FoxO1 and HOMA-IR were higher in the GDM group than those in the control group(P＜0.01).Pearson correlation analysis showed that serum levels of Spexin and FoxO1 in GDM patients were positively correlated with HOMA-IR,and serum level of Spexin was positively correlated with FoxO1(P＜0.05).The incidences of gestational hypertension,cesarean section,macrosomia,neonatal malformations,low birth weight infants and neonatal asphyxia were higher in the GDM group than those in the control group(P＜0.05).Serum levels of Spexin and FoxO1 and FINS,FBG and HOMA-IR were significantly higher in the adverse pregnancy group than those in the good pregnancy group(P＜0.01).Multivariate Logistic regression analysis showed that the increased Spexin and FoxO1 were the risk factor for adverse pregnancy outcomes in GDM patients(P＜0.01).The ROC curve analysis showed that the area under the curve(AUC)of serum Spexin and FoxO1 levels for predicting pregnancy outcomes in GDM patients was 0.887 and 0.883,respectively,and the AUC of combined prediction was 0.942.Conclusion Serum levels of Spexin and FoxO1 are elevated in GDM patients,and both are related to IR.The combination of the two can assist in judging the pregnancy outcome of GDM patients.

To understand the progress of, summarize the lessons learned from and analyze the challenges in the national schistosomiasis elimination program of China in 2024, this article presented the endemic situation of schistosomiasis and national schistosomiasis surveillance results in the People’s Republic of China in 2024. By the end of 2024, Shanghai Municipality, Zhejiang Province, Fujian Province, Guangdong Province and Guangxi Zhuang Autonomous Region continued to consolidate schistosomiasis elimination achievements, and 7 provinces of Jiangsu, Sichuan, Yunnan, Hubei, Hunan, Anhui and Jiangxi maintained the criteria of schistosomiasis transmission interruption. A total of 450 counties (cites, districts) were found to be endemic for schistosomiasis in China in 2024, including 26 061 endemic villages covering 73 630 500 residents at risk of infections. Among the 450 counties (cities, districts) endemic for schistosomiasis, 388 (86.22%) achieved the criteria of schistosomiasis elimination and 62 (13.78%) achieved the criteria of transmission interruption. In 2024, a total of 4 102 624 individuals received immunological tests for schistosomiasis in China, with 44 823 sero-positives identified (1.09% seroprevalence), and a total of 169 722 individuals received parasitological examinations, with 1 egg-positives detected. A total of 27 321 cases with advanced schistosomiasis were documented in China by the end of 2024. In 2024, a total of 575 686 bovines were raised in schistosomiasis-endemic villages of China, and 113 842 bovines received immunological tests, with 235 sero-positives detected (0.21% seroprevalence), while no egg-positives were identified among the 167 475 bovines receiving parasitological examinations. In 2024, snail survey was performed covering an area of 680 498.27 hm² in China, and 190 778.66 hm² snail habitats were identified, including 59.09 hm² emerging snail habitats and 704.23 hm² reemerging snail habitats. In 2024, a total of 19 665 schistosomiasis patients receiving chemotherapy with praziquantel in China, and expanded chemotherapy was given to humans at 571 722 person-times and to bovines at 306 740 herd-times. In addition, snail control with chemical treatment covered 117 111.37 hm² snail habitats across China in 2024, and the actual area of chemical treatment was 66 562.95 hm², while environmental improvements were performed in snail habitats covering an area of 1 374.26 hm². The national schistosomiasis surveillance results showed that the mean prevalence rates of Schistosoma japonicum infections were both 0 among humans and bovines in China in 2024, and no S. japonicum infection was detected in snails. These data demonstrated that the prevalence of schistosomiasis remained at a low level in China in 2024; however, the areas of snail habitats remained high and the number of fenced cattle showed a slight increase. To address these risks, it is imperative to maintain the integrated strategy with an emphasis on management of the source of S. japonicum infection and intensified snail control in high-risk areas, and to reinforce schistosomiasis surveillance and forecast and snail control in high-risk areas.

Objective:To apply artificial intelligence（AI）in classifying ovarian tumors on ultrasound images，and compare the diagnostic results of several sonographers with varying seniority levels.Methods:A total of 645 patients diagnosed with adnexal masses via gynecological ultrasound examination at Qilu Hospital of Shandong University from January 2021 to December 2024 were enrolled. Three deep learning architectures，i.e.，Alexnet，Densenet121，and Resnet50 were developed and used to internally test the classification effectiveness of ovarian tumors，while the optimal model was selected for external testing. Two junior sonographers and two senior sonographers were recruited to independently diagnose ovarian tumors in the external test dataset. Subsequently，the benign and malignant results of the model's predictions were disclosed to each sonographer，and their revised diagnoses on the same external test data in combination with the best AI model were recorded.Results:The optimal model achieved an accuracy of 0.941，sensitivity of 0.936，and specificity of 0.944 on the internal test dataset，and maintained robust performance on the external test dataset with accuracy of 0.891，sensitivity of 0.880，and specificity of 0.907. Compared to junior sonographers，the optimal model demonstrated significantly higher sensitivity in discriminating benign from malignant ovarian tumors（0.880 vs. 0.723，0.602；all P<0.05）. No statistically significant difference was observed in diagnostic accuracy between the optimal model and senior sonographer 1（ P=0.05）. With assistance from the optimal model，junior sonographers achieved significant improvements in both sensitivity and specificity（sensitivity：0.723 vs. 0.843，0.602 vs. 0.819；specificity：0.778 vs. 0.833，0.685 vs. 0.741；all P<0.05）. Conclusions:The optimal model achieves comparable performance to that of senior sonographers in ovarian tumor classification. With model assistance，the diagnostic performance of junior sonographers is significantly improved.

Objective:To investigate the effect of titanium wire-absorbable suture dual line combined firm stitching technique in costal cartilage framework shaping for auricular reconstruction in congenital microtia patients.Methods:A retrospective study was conducted on 120 patients with congenital microtia who underwent auricular reconstruction surgery at the Plastic Surgery Hospital of Chinese Academy of Medical Sciences and Peking Union Medical College from January 2020 to December 2021. Among these, 86 were male and 34 were female, with an age range of 6-15 (8.5±2.1) years. All patients underwent auricular reconstruction using the expanded skin flap method, and the titanium wire-absorbable suture dual line combined firm stitching technique was used to construct a multi-layer three-dimensional autologous costal cartilage framework. Postoperative follow-up was conducted for 1 to 3 years to evaluate the morphology, stability, patient satisfaction, and occurrence of adverse reactions.Results:Of the 120 patients, 119 (99.2%) achieved primary healing. The reconstructed auricles were lifelike with clear substructures, and the long-term shape of the auricles remained stable without significant deformation. One patient developed a local skin infection and ulceration, leading to exposure of the cartilage framework, which was successfully repaired using a temporal fascia flap and free skin graft. A total of 85.8% (103/120) of the patients were satisfied with the postoperative results, 13.3% (16/120) rated the outcome as average, and 0.8% (1/120) were dissatisfied. No cases of hematoma or flap necrosis were observed in any of the patients.Conclusion:The costal cartilage framework, constructed using the titanium wire-absorbable suture dual line combined firm stitching technique, demonstrates good clinical effects for auricular reconstruction with no severe adverse reactions.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.
