Objective:To investigate the value of radiomics nomogram based on standardized pre-treatment chest enhanced CT in predicting the mutation status of epidermal growth factor receptor (EGFR) for patients with lung adenocarcinoma.Methods:A retrospective analysis was conducted on pre-treatment chest enhanced CT images and clinical data of 262 patients from the affiliated hospital of Jining Medical University with pathologically proven primary lung adenocarcinoma who received EGFR gene testing, including EGFR wild type ( n=122) and mutant type ( n=140). The patients were divided into training group ( n=183) and testing group ( n=79) according to a ratio of 7∶3 by stratified sampling method. Standardized pre-processed the images, delineated the ROI and extracted the radiomics features. Least absolute shrinkage and selection operator (LASSO) algorithm was used to reduce the dimension and select key features. The standardized radiomics model, clinical model and the combined model were established by Logistic Regression (LR) machine learning method. Calculated the Rad-score and drew the nomogram. ROC curve and Delong were used to evaluate and compare the predictive performance of different models. Results:23 standardized enhanced CT radiomics features and 4 clinical features were selected. The predictive performance of standardized radiomics model was better than that of non-standardized radiomics model [area under curve (AUC): 0.863 vs. 0.805, t=2.19, P<0.05]. The AUCs of the combined model and standardized radiomics model were higher than that of the clinical model (training group: 0.885, 0.863 vs. 0.774, t=3.57, 2.17, P<0.05; testing group: 0.873, 0.829 vs. 0.763, t=2.19, 2.02, P<0.05). The radiomics nomogram was built based on Rad-score, age, sex, smoking history and BMI. Conclusions:The combined model and standardized radiomics model could effectively predict the mutation status of EGFR gene in lung adenocarcinoma patients before treatment, providing valuable clinical insights.

Objective:To summarize the progress in research of economic evaluation of HIV vaccination strategies in the world, and provide reference for future decision-making and research on HIV vaccination.Methods:The key words used for literature retrieval were "HIV/AIDS", and "vaccine/vaccination" and "economic evaluation/cost-effectiveness analysis/cost-utility analysis/cost-benefit analysis/HTA". Literatures about the economic evaluation of HIV vaccination strategies published as of July 31, 2022, were retrieved from Wanfang Data (Wanfang), China Hospital Knowledge Database (CHKD), and PubMed databases. The quality of the articles was evaluated and analyzed comprehensively.Results:A total of 17 study articles with good quality were included. Results from the comprehensive analysis showed that HIV vaccination is a cost-saving or cost-effective strategy for key populations or the whole population. HIV vaccination could effectively reduce new infections and improve the quality of life of population. Factors, such as vaccine efficiency, coverage rate, price, and risk behavior change after vaccination, would affect the vaccination effect in different targeted populations.Conclusions:There were limited high-quality research data about the economic evaluation of HIV vaccination strategies. It is necessary to conduct in-depth research based on real-world evidence.

Objective To investigate the effects of Huoxue Yiqi Decoction(composed of Carthami Flos,Crataegi Fructus,Salviae Miltiorrhizae Radix et Rhizoma,and Astragali Radix)combined with Pinggan Qianyang Muzu Powder(composed of Uncariae Ramulus cum Uncis,Prunellae Spica,Chrysanthemi Flos,Lonicerae Japonicae Flos and Cassiae Semen)on blood lipid metabolism and cardiac function in female patients with essential hypertension.Methods A total of 220 female patients with essential hypertension of qi deficiency and blood stasis type were randomly divided into observation group and control group,with 110 cases in each group.The control group was treated with conventional western medicine,and the observation group was treated with Huoxue Yiqi Decoction orally combined with Pinggan Qianyang Muzu Powder for foot bath on the basis of treatment for the control group.The course of treatment for the two groups covered one month.Before and after treatment,the two groups were observed in the changes of blood pressure,blood lipid,traditional Chinese medicine(TCM)syndrome scores and cardiac function indicators of left ventricular ejection fraction(LVEF)and stroke volume(SV).After treatment,the clinical efficacy of the two groups was evaluated.Results(1)After one month of treatment,the total effective rate of the observation group was 95.45%(105/110),and that of the control group was 84.55%(93/110).The intergroup comparison(tested by chi-square test)showed that the efficacy of the observation group was superior to that of the control group(P＜0.01).(2)After treatment,the TCM syndrome scores of primary symptoms and secondary symptoms in the two groups were decreased when compared with those before treatment(P＜0.05),and the decrease in the observation group was superior to that in the control group(P＜0.01).(3)After treatment,the levels of systolic blood pressure(SBP)and diastolic blood pressure(DBP)in the two groups were lower than those before treatment(P＜0.05),and the decrease of SBP and DBP levels in the observation group was significantly superior to that in the control group(P＜0.01).(4)After treatment,the levels of blood lipid indicators of total cholesterol(TC),triglyceride(TG)and low density lipoprotein cholesterol(LDL-C)in the two groups were lower than those before treatment(P＜0.05),and the levels of high density lipoprotein cholesterol(HDL-C)were higher than those before treatment(P＜0.05).The decrease of TC,TG and LDL-C levels and the increase of HDL-C level in the observation group were significantly superior to those in the control group(P＜0.01).(5)After treatment,the levels of cardiac function indicators of LVEF and SV in the two groups were higher than those before treatment(P＜0.05),and the increase of LVEF and SV levels in the observation group was significantly superior to that in the control group(P＜0.01).Conclusion The combination of Huoxue Yiqi Decoction and Pinggan Qianyang Muzu Powder exerts certain effect in the treatment of female patients with essential hypertension of qi deficiency and blood stasis type.The combined therapy is effective on controlling blood pressure,improving blood lipid metabolism and cardiac function indicators.

Objective:To evaluate the efficacy and safety of intensity modulated radiotherapy (IMRT) and programmed death-1 (PD-1) immunotherapy combined with single-agent chemotherapy for patients with local failure of esophageal cancer after initial radical chemoradiotherapy.Methods:Clinical data of 80 patients with local failure of esophageal cancer after initial radical chemoradiotherapy treated with IMRT or PD-1 immunotherapy combined with single-agent chemotherapy in People's Hospital of Xinghua between June 2014 and June 2023 were retrospectively analyzed. IMRT was delivered at 1.8-2.0 Gy per fraction, 5 fractions per week, with a total dose of 45.0-60.0 Gy in 40 patients (IMRT group). The other 40 patients received PD-1 immunotherapy combined with single-agent chemotherapy (PD-1 immunotherapy combined with single-agent chemotherapy group). Kaplan-Meier method was used for univariate analysis and the cumulative survival probability. Log-rank test was used for survival significance test. Cox proportional hazards model was used for multivariate analysis of related factors affecting overall survival (OS), progression-free survival (PFS) and local control (LC).Results:By December 2023, the follow-up rate was 100%. The 1- and 2-year OS rates in the IMRT group were 66.1% and 18.9%, with a median OS time of 10.1 months. In the PD-1 immunotherapy combined with single-agent chemotherapy group, the 1- and 2-year OS rates were 72.3% and 36.9%, with a median OS time of 12.4 months. There was a significant difference in OS rates between two groups ( χ2=3.89, P=0.049). The 1- and 2-year PFS rates in the IMRT group were 47.4% and 31.6%, with a median PFS time of 8.5 months. In the PD-1 immunotherapy combined with single-agent chemotherapy group, the 1- and 2-year PFS rates were 70.0% and 64.2%, with a median PFS time of 11.9 months. There was no significant difference in the PFS rates between two groups ( χ2=2.66, P=0.103). The 1- and 2-year LC rates in the IMRT group were 68.6% and 62.3%, with a median LC time of 8.9 months. In the PD-1 immunotherapy combined with single-agent chemotherapy group, the 1- and 2-year LC rates were 72.8% and 66.7%, with a median LC time of 12.0 months. There was no significant difference in LC rates between two groups ( χ2=0.18, P=0.672). Grade 2 radiation esophagitis and radiation pneumonitis developed in 82.5% (33/40) and 32.5% (13/40) in the IMRT group, respectively. The incidence of grade 1-2 peripheral blood leukopenia was 40.0% (16/40), 50.0% (20/40) for grade 1-2 peripheral blood thrombocytopenia, 27.5% (11/40) for moderate to severe anemia, and 20.0% (8/40) for grade 1-2 thyroid dysfunction in the PD-1 immunotherapy combined with single-agent chemotherapy, respectively. Single- and multi-factor analysis showed that the failure site ( χ2=9.01, P=0.011) and short-term efficacy ( χ2=7.78, P=0.005) were the independent prognostic factors affecting OS. The short-term efficacy was the independent prognostic factor for PFS ( χ2=31.63, P<0.001). The short-term efficacy was the independent prognostic factors affecting LCS ( χ2=17.64, P=0.001) too. Conclusion:For the patients with local failure of esophageal cancer after initial radical chemoradiotherapy, the combination of PD-1 immunotherapy with single-agent chemotherapy yields better survival prognosis than re-irradiation alone, but it is still necessary to pay attention to the related drug toxicities.

Objective: To compare the efficacies between open surgery and axillary non-inflatable endoscopic surgery in papillary thyroid carcinoma (PTC). Methods: A retrospective analysis was performed on 343 patients with unilateral PTC treated by traditional open surgery (201 cases) and transaxillary non-inflating endoscopic surgery (142 cases) from May 2019 to December 2021 in the Head and Neck Surgery of Sichuan Cancer Hospital. Among them, 97 were males and 246 were females, aged 20-69 years. 1∶1 propensity score matching (PSM) was performed on the enrolled patients, and the basic characteristics, perioperative clinical outcomes, postoperative complications, postoperative quality of life (Thyroid Cancer-Specific Quality of Life), aesthetic satisfaction and other aspects of the two groups were compared after successful matching. SPSS 26.0 software was used for statistical analysis. Results: A total of 190 patients were enrolled after PSM, with 95 cases in open group and 95 cases in endoscopic group. Intraoperative blood losses for endoscopic and open groups were [20 (20) ml vs. 20 (10) ml, M (IQR), Z=-2.22], postoperative drainage volumes [170 (70)ml vs. 101 (55)ml, Z=-7.91], operative time [135 (35)min vs. 95 (35)min, Z=-7.34], hospitalization cost [(28 188.7±2 765.1)yuan vs. (25 643.5±2 610.7)yuan, x¯±s, t=0.73], postoperative hospitalization time [(3.1±0.9)days vs. (2.6±0.9)days, t=-3.24], and drainage tube placement time [(2.5±0.8) days vs. (2.0±1.0)days, t=-4.16], with statistically significant differrences (all P<0.05). There was no significant difference in surgical complications (P>0.05). There were significant diffferences between two groups in the postoperative quality of life scores in neuromuscular, psychological, scar and cold sensation (all P<0.05), while there were no statistically significant differences in other quality of life scores (all P>0.05). In terms of aesthetic satisfaction 6 months after surgery, the endoscopic group was better than the open group, with statistically significant difference (χ²=41.47, P<0.05). Conclusion: Endoscopic thyroidectomy by a gasless unilateral axillary approach is a safe and reliable surgical method, which has remarkable cosmetic effect and can improve the postoperative quality of life of patients compared with the traditional thyroidectomy.

Background In mainland China, patients with neovascular age-related macular degeneration (nAMD) have approximately an 40% prevalence of polypoidal choroidal vasculopathy (PCV). This disease leads to recurrent retinal pigment epithelium detachment (PED), extensive subretinal or vitreous hemorrhages, and severe vision loss. China has introduced various treatment modalities in the past years and gained comprehensive experience in treating PCV.Methods A total of 14 retinal specialists nationwide with expertise in PCV were empaneled to prioritize six questions and address their corresponding outcomes, regarding opinions on inactive PCV, choices of anti-vascular endothelial growth factor (anti-VEGF) monotherapy, photodynamic therapy (PDT) monotherapy or combined therapy, patients with persistent subretinal fluid (SRF) or intraretinal fluid (IRF) after loading dose anti-VEGF, and patients with massive subretinal hemorrhage. An evidence synthesis team conducted systematic reviews, which informed the recommendations that address these questions. This guideline used the GRADE (Grading of Recommendations, Assessment, Development, and Evaluation) approach to assess the certainty of evidence and grade the strengths of recommendations. Results The panel proposed the following six conditional recommendations regarding treatment choices. (1) For patients with inactive PCV, we suggest observation over treatment. (2) For treatment-na?ve PCV patients, we suggest either anti-VEGF monotherapy or combined anti-VEGF and PDT rather than PDT monotherapy. (3) For patients with PCV who plan to initiate combined anti-VEGF and PDT treatment, we suggest later/rescue PDT over initiate PDT. (4) For PCV patients who plan to initiate anti-VEGF monotherapy, we suggest the treat and extend (T&E) regimen rather than the pro re nata (PRN) regimen following three monthly loading doses. (5) For patients with persistent SRF or IRF on optical coherence tomography (OCT) after three monthly anti-VEGF treatments, we suggest proceeding with anti-VEGF treatment rather than observation. (6) For PCV patients with massive subretinal hemorrhage (equal to or more than four optic disc areas) involving the central macula, we suggest surgery (vitrectomy in combination with tissue-plasminogen activator (tPA) intraocular injection and gas tamponade) rather than anti-VEGF monotherapy. Conclusions Six evidence-based recommendations support optimal care for PCV patients' management.

【Objective】 To explore the influencing factors of adolescent runaway and its correlation with family health so as to provide epidemiological evidence for future comprehensive interventions. 【Methods】 Using the quota sampling method, 1 065 adolescents aged 12-18 years old were surveyed by Questionnaire Star in 120 cities in China from July to September 2021. A well-developed electronic questionnaire was used to collect information about demographic characteristics, psychological characteristics, family health, social support, and behavior of running away from home. Univariate analysis and Logistic regression were used to explore the influencing factors of adolescent runaway and its correlation with family health. 【Results】 A total of 1 065 adolescents were investigated, among whom 334 were the only children (31.36%) and 442 were boys (41.50%). Univariate analysis revealed that 7.6% of teenagers had the experience of running away from home in the last 30 days. Participants who were ethnic minorities (P=0.031) and had education of technical school or junior college (P=0.029) and a low family income (P<0.001) were more likely to have running away behavior. Adolescents with low self-efficacy (P=0.005), depression (P<0.001), anxiety (P<0.001), and more stress had higher detection rates of runaway behavior. However, adolescents with higher family health and social support were less likely to run away from home (P<0.01). Multivariate analysis showed that compared with adolescents with low family health, adolescents with high (OR=0.16, 95% CI: 0.06-0.46) and moderate (OR=0.27, 95% CI: 0.14-0.55) family health had a significantly lower risk of runaway behavior. 【Conclusion】 The family is of great significance in preventing teenagers from running away from home. Parents should build a good parent-child relationship and create a happy family atmosphere to reduce the occurrence of teenagers running away from home.

To investigate the prevalence of diabetes mellitus (DM) among residents in Chongchuan district, Nantong city in 2012 and 2018, and evaluate the effectiveness of community comprehensive management of DM. Based on the data of 17 780 and 13 382 residents in the cross-sectional surveys of the " National Demonstration Area for Comprehensive Prevention and Control of Chronic Diseases " project in Chongchuan District of Nantong City, Jiangsu Province in 2012 and 2018, 4 583 and 3 996 DM-related information were obtained. The population of Jiangsu Province in 2012 and 2018 was used as the reference for standardization. The rates of prevalence and management (including awareness, treatment, treatment of patients who knew their diabetic situation, control and control of patients under treatment) of DM in the two surveys were compared using chi-square test. The results showed that in 2012 and 2018, the prevalence rates of DM were 12.0% and 15.7% (χ²=24.25, P<0.05), and the standardized rates were 10.1% and 10.8% (χ²=1.05, P=0.306). The incidence rates were 5.7% and 2.3%, respectively (χ²=55.60, P<0.05). The standardized prevalence rates in the two surveys were 9.7% and 11.6% for males (χ²=3.66, P=0.056) and 10.5% and 9.9% for females (χ²=0.50, P=0.481), 7.2% and 6.5% (χ²=0.85, P=0.357) for people aged 18-59 years old and 20.6% and 21.9% (χ²=0.91, P=0.339) for people aged 60 years and over, respectively. The standardized rates of awareness, treatment, treatment of patients who knew their diabetic situation, control, and control of patients under treatment in 2018 were 84.4%, 80.3%, 95.2%, 58.4%, and 70.2%, respectively, higher than 47.2%, 23.4%, 44.8%, 30.4% and 59.4% in 2012 (χ²=183.33, χ²=380.65, χ²=282.99, χ²=93.24, χ²=6.22, all P<0.05). Among men, the standardized rates of awareness, treatment, treatment of patients who knew their diabetic situation, and control in 2018 were 85.8%, 78.8%, 91.8% and 62.7%, higher than 50.5%, 37.5%, 72.3% and 32.6% in 2012 (χ²=78.40, χ²=96.17, χ²=27.55, χ²=48.96, all P<0.05). Similarly, the standardized management rates in 2018 were 83.0%, 81.7%, 98.5%, 54.1% and 65.1%, higher than 44.0%, 10.0%, 18.3%, 28.2% and 48.8% in 2012 among women (χ²=105.52, χ²=326.36, χ²=317.22, χ²=43.34, χ²=3.87, all P<0.05). The standardized rates of awareness, treatment, treatment of patients who knew their diabetic situation, and control of people aged 18-59 and 60 years and over were 82.9%, 79.7%, 96.1%, 55.0% and 88.0%, 81.8%, 93.0% and 67.2%, higher than 42.6%, 19.8%, 42.2%, 27.5% and 63.9%, 36.8%, 53.9%, 40.8% in 2012 (χ²=44.51, χ²=102.17, χ²=57.78, χ²=21.65, all P<0.05; χ²=71.18, χ²=181.55, χ²=146.26, χ²=59.23, all P<0.05). The comprehensive prevention and control system of chronic diseases, which comprehensively covered the life of community residents, had good management effect on DM, and effectively promoted health education and health promotion.
