Objective To investigate the screening results and factors affecting abnormal detection rates among high-risk groups of esophageal cancer and to explore effective intervention measures. Methods We investigated and collected the information on gender, education level, age, marital status, symptoms of reflux esophagitis (heartburn, acid reflux, belching, hiccup, foreign body sensation in the pharynx, and difficulty swallowing), consumption of pickled vegetables, salt use, and esophageal cancer incidence of villagers in a natural village in Wenfeng District, Anyang City, Henan Province. Changes in reflux esophagitis symptoms in the high-incidence area of esophageal cancer before and after 16 years were observed, and the relationship of such changes with esophageal cancer was analyzed. Results In 2008, 711 cases were epidemiologically investigated, including 213 cases with one of the symptoms of reflux esophagitis such as heartburn, acid reflux, belching, hiccups, foreign body sensation in the pharynx, and difficulty swallowing (sorted in accordance with the abovementioned symptoms; if there are multiple symptoms, then the former is taken); 55 cases with at least two related symptoms, among which the most symptom was heartburn in 108 cases (15.1%); followed by acid reflux, belching, etc. In 2024, the same group of people was investigated, and eight people were missing because of relocation. A total of 703 people were successfully investigated, of which 189 cases (26.8%) had one of the symptoms of reflux esophagitis, such as heartburn (sorted in accordance with relevant symptoms, if there are multiple symptoms, then the former will be selected); 167 cases (23.7%) had at least two related symptoms, among which the most symptom was heartburn in 139 cases (19.7%); followed by acid reflux. Over 16 years, among the 703 people investigated, 45 cases had esophageal cancer and they had one or more of the abovementioned symptoms. No significant differences in the reflux esophagitis-like symptoms were found between 2008 and 2024 (P=0.26); no significant differences in the composition of reflux esophagitis-like symptoms were found between 2008 and 2024 (P=0.299). Conclusion The detection rate of reflux esophagitis-related symptoms in the population in a high-risk area of esophageal cancer has not decreased in the past 16 years, and the high-risk factors still exist. Esophageal cancer is closely related to reflux esophagitis, and clinical practice can provide early diagnosis and treatment for high-risk population.

Objective To understand the disease spectrum of a natural village in an area with high incidence of esophageal cancer to provide a reference for precise prevention and control. Methods From 2008 to 2024, 711 asymptomatic people over the age of 35 years in a natural village with high incidence of esophageal cancer in China were surveyed, and 171 of them were subjected to gastroscopy, biopsy, and pathological examination. All participants were followed up for a long time, and their disease history was recorded. Results A total of 16 years of follow-up were performed, and 703 people were effectively followed up. In 2008, 171 people underwent gastroscopy, and 160 people had biopsy and pathological results in endoscopic screening. By 2024, 76 people had been diagnosed with malignant tumors of 12 different types, and among these people, 45 had esophageal cancer. Conclusion Esophageal cancer remains a significant cause of morbidity and mortality from malignant tumors in this region. Biopsy and pathological examination should be strengthened during gastroscopy, and follow-ups and regular check-ups should be given high importance to reduce the incidence and mortality rates of esophageal cancer.

Objective: To analyze the disease burden of chronic obstructive pulmonary disease (COPD) and changes in its risk factors among residents in Zhejiang Province from 1990 to 2021, so as to identify key priorities for COPD prevention and control. Methods: Data on COPD mortality and disability-adjusted life years (DALY) for residents in Zhejiang Province from 1990 to 2021 were collected from the Global Burden of Disease (GBD) 2021 database. Standardized mortality and standardized DALY rate were calculated using the GBD 2021 world population standard structure. Premature mortality was computed via the life table method. The average annual percent change (AAPC) was applied to analyze trends in COPD mortality, DALY rate, and premature mortality. Changes in deaths of COPD risk factors were evaluated using population attributable fraction (PAF). Results: From 1990 to 2021, the standardized COPD mortality in Zhejiang Province decreased from 272.40/100 000 to 70.56/100 000 (AAPC=-4.395%), and the standardized DALY rate declined from 4 167.37/100 000 to 1 071.89/100 000 (AAPC=-4.396%). Similar downward trends were observed in both males (AAPC=-3.933%, -4.173%) and females (AAPC=-4.785%, -4.480%), all P<0.05. Crude mortality and DALY rates increased with age, and the crude mortality and DALY rates of various age groups in Zhejiang Province showed decreasing trends from 1990 to 2021 (all P<0.05). The premature mortality declined from 4.37% to 0.60% from 1990 to 2021 (AAPC=- 6.206%), with consistent trends across males and females (AAPC=- 6.144%, - 6.379%, all P<0.05). From 1990 to 2021, particulate matter pollution showed the largest reduction in PAF (- 56.76%), while ambient ozone pollution had the largest increase (103.07%) in Zhejiang Province. By 2021, smoking became the leading risk factor for deaths of COPD (PAF=43.32%). Conclusions The standardized mortality, standardized DALY rate, and premature mortality for COPD show consistent declining trends in Zhejiang Province from 1990 to 2021. However, risk factors such as smoking and ambient ozone pollution require intensified focus to further reduce disease burden of COPD.

Recently, male reproductive health has attracted extensive attention, with the adverse effects of circadian disruption on male fertility gradually gaining recognition. However, the mechanism by which circadian disruption leads to damage to male reproductive system remains unclear. In this review, we first summarized the dual regulatory roles of circadian clock genes on the male reproductive system: (1) circadian regulation of testosterone synthesis via the hypothalamic-pituitary-testicular (HPT) and hypothalamic-pituitary-adrenal (HPA) axes; (2) non-circadian regulation of spermatogenesis. Next, we further listed the possible mechanisms by which circadian disruption impairs male fertility, including interference with the oscillatory function of the reproductive system, i.e., synchronization of the HPT axis, crosstalk between the HPT axis and the HPA axis, as well as direct damage to germ cells by disturbing the non-oscillatory function of the reproductive system. Future research using spatiotemporal omics, epigenomic assays, and neural circuit mapping in studying the male reproductive system may provide new clues to systematically unravel the mechanisms by which circadian disruption affects male reproductive system through circadian clock genes.

COMPERA 2.0 risk stratification has been demonstrated to be useful in patients with precapillary pulmonary hypertension (PH). However, its suitability for patients at risk for post-capillary PH or PH associated with left heart disease (PH-LHD) is unclear. To investigate the use of COMPERA 2.0 in patients with severe aortic stenosis (SAS) undergoing transcatheter aortic valve replacement (TAVR), who are at risk for post-capillary PH, a total of 327 eligible SAS patients undergoing TAVR at our institution between September 2015 and November 2020 were included in the study. Patients were classified into four strata before and after TAVR using the COMPERA 2.0 risk score. The primary endpoint was all-cause mortality. Survival analysis was performed using Kaplan-Meier curves, log-rank test, and Cox proportional hazards regression model. The study cohort had a median (interquartile range) age of 76 (70‒80) years and a pulmonary arterial systolic pressure of 33 (27‒43) mmHg (1 mmHg=0.133 kPa) before TAVR. The overall mortality was 11.9% during 26 (15‒47) months of follow-up. Before TAVR, cumulative mortality was higher with an increase in the risk stratum level (log-rank, both P<0.001); each increase in the risk stratum level resulted in an increased risk of death (hazard ratio (HR) 2.53, 95% confidential interval (CI) 1.54‒4.18, P<0.001), which was independent of age, sex, estimated glomerular filtration rate (eGFR), hemoglobin, albumin, and valve type (HR 1.76, 95% CI 1.01‒3.07, P=0.047). Similar results were observed at 30 d after TAVR. COMPERA 2.0 can serve as a useful tool for risk stratification in patients with SAS undergoing TAVR, indicating its potential application in the management of PH-LHD. Further validation is needed in patients with confirmed post-capillary PH by right heart catheterization.

Radiopharmaceuticals operate by combining radionuclides with carriers. The radiation energy emitted by radionuclides is utilized to selectively irradiate diseased tissues while minimizing damage to healthy tissues. In comparison to external beam radiation therapy, radionuclide drugs demonstrate research potential due to their biological targeting capabilities and reduced normal tissue toxicity. This article reviews the applications and research progress of radiopharmaceuticals in cancer treatment. Several key radionuclides are examined, including ²²³Ra, ⁹⁰Y, Lutetium-177 (¹⁷⁷Lu), ²¹²Pb, and Actinium-225 (²²⁵Ac). It also explores the current development trends of radiopharmaceuticals, encompassing the introduction of novel radionuclides, advancements in imaging technologies, integrated diagnosis and treatment approaches, and equipment-medication combinations. We review the progress in the development of new treatments, such as neutron capture therapy, proton therapy, and heavy ion therapy. Furthermore, we examine the challenges and breakthroughs associated with the clinical translation of radiopharmaceuticals and provide recommendations for the research and development of novel radionuclide drugs.

Objective:To investigate the clinical efficacy of bilateral V-Y advancement island flaps on buttocks in repairing postoperative defects in patients with perianal Paget′s disease.Methods:From January 2009 to January 2021, a retrospective analysis was performed on clinical data collected from 13 patients with perianal Paget′s disease, whose perianal defects resulting from the tumor resection were reconstructed with bilateral V-Y advancement island flaps on the buttocks in the Department of Dermatology, Hangzhou Third People′s Hospital. The postoperative recovery of the buttocks and the effects on the defecation function were evaluated.Results:The areas of perianal defects in 13 cases ranged from 4.8 cm × 5.6 cm to 12.2 cm × 6.4 cm. All defects were successfully repaired by using the bilateral V-Y advancement island flaps, and all surgical wounds healed primarily. One case first received temporary ileostomy, and then received ileostomy closure 3 months later, resulting in the recovery of defecation function; in another 1 case of perianal Paget′s disease comorbid with rectal cancer, the permanent sigmoid colostomy was performed to divert feces, and the defecation function was lost. After the follow-up for 1 - 6 years, the buttocks were symmetrical in shape in all the 13 patients, and 12 with preserved anus had normal defecation function. No tumor recurrence was observed in 12 patients without other malignant tumors after the operation, while 3 patients experienced mild anal stenosis without anal mucosa eversion or wound dehiscence; 1 patient with perianal Paget′s disease complicated by anal canal adenocarcinoma developed bilateral inguinal lymph node and internal iliac lymph node metastasis 1 year after the operation, and died 6 months later.Conclusion:The bilateral V-Y advancement island flaps on the buttocks have the advantages of reliable blood supply and sufficient advancement mobility, and can be used to repair large skin defects around the anus.

Objective Evaluation of the clinical efficacy of f trochanteric flip osteotomy combined with Kocher-Langen-beck approach for high acetabular posterior wall fracture.Methods Between January 2020 and December 2022,20 patients with high acetabular posterior wall fractures were retrospectively analyzed,including 12 males and 8 females,aged 18 to 75 years old.They were divided into two groups according to the different surgical methods.Ten patients were treated with greater trochanteric osteotomy combined with Kocher-Langenbeck approach as the observation group,including 5 males and 5 fe-males,aged from 18 to 75 years old.Ten patients were treated with Kocher-Langenbeck approach alone as the control group,including 7 males and 3 females,aged from 18 to 71 years old.Matta reduction criteria were used to evaluate the reduction quality of the two groups,and Harris score was used to compare the hip function of the two groups at the latest follow-up.The operation time,blood loss and postoperative complications of the two groups were analyzed.Results All patients were followed up for 10 to 24 months.According to the Matta fracture reduction quality evaluation criteria,the observation group achieved anatomical reduction in 6 cases,satisfactory reduction in 3 cases,and unsatisfactory reduction in 1 case,while the control group only achieved anatomical reduction in 3 cases,satisfactory reduction in 3 cases,and unsatisfactory reduction in 4 cases.At the final follow-up,the Harris hip score ranged from 71.4 to 96.6 in the observation group and 65.3 to 94.5 in the control group.According to the results of Harris score.The hip joint function of the observation group was excellent in 6 cases,good in 3 cases,and fair in 1 case.The hip joint function of the control group was excellent in 2 cases,good in 3 cases,fair in 3 cases,and poor in 2 cases.In the observation group,the intraoperative blood loss ranged from 300 to 700 ml,and the operation dura-tion ranged from 120 to 180 min;in the control group,the intraoperative blood loss ranged from 300 to 650 ml,and the opera-tion duration ranged from 100 to 180 min.Complications in the observation group included 1 case of traumatic arthritis and 1 case of heterotopic ossification,while complications in the control group included 3 cases of traumatic arthritis,3 cases of het-erotopic ossification and 1 case of hip abduction weakness.Conclusions Trochanteric flip osteotomy combined with the Kocher-Langenbeck approach significantly improved anatomical fracture reduction rates,enhanced excellent and good hip joint function outcomes,and reduced surgical complication incidence compared to the Kocher-Langenbeck approach alone.Clinical application of this combined approach is promising,although larger studies are needed for further validation.

Objective:To investigate the effect of overexpression of T cell restricted intracellular antigen 1(TIA1)gene in M2-type tumor-associated macrophages(M2-TAMs)on invasion and migration of gastric cancer cells and its mechanism.Methods:Primary TAMs were extracted from gastric cancer tissues and induced to differentiate into M2-TAMs using IL-4 and IL-13.The TIA1 overex-pression plasmid(oe-TIA1)and its empty vector were transfected into M2-TAMs.The expression levels of TIA1 mRNA and protein were detected by qRT-PCR and Western blot.The expression levels of CD206 and CD163 were detected by flow cytometry.The levels of IL-10,TGF-β,VEGF-A and Arg-1 in cell culture supernatant were detected by ELISA.The transfected M2-TAMs were co-cultured with gastric cancer BGC-823 cells by Transwell co-cultivation system,and PI3K agonist 740Y-P was used to intervene in parallel.The cell migration ability was detected by scratch assay.Transwell assay was used to detect cell invasion ability.Protein expression levels of PI3K,p-PI3K,AKT,p-AKT,MMP-2 and MMP-9 in the cells were detected by Western blot.Results:①Compared with primary TAMs,the levels of CD206 and CD163 expression in M2-TAMs cells and IL-10,TGF-β,VEGF-A and Arg-1 in cell culture superna-tant were significantly increased(P<0.05),while the expression levels of TIA1 mRNA and protein were significantly decreased(P<0.05).Overexpression of TIA1 gene significantly decreased the expression levels of CD206 and CD163 in M2-TAMs and IL-10,TGF-β,VEGF-A and Arg-1 in cell culture supernatant(P<0.05).②Overexpression of TIA1 gene in M2-TAMs could significantly reduce the migration and invasion ability and the expression levels of p-PI3K/PI3K,p-AKT/AKT,MMP-2 and MMP-9 proteins in BGC-823 cells(P<0.05).③740Y-P could significantly reverse the inhibitory effects of overexpression of TIA1 gene in M2-TAMs on migration,inva-sion and PI3K/AKT signaling pathway of BGC-823 cells.Conclusion:Overexpression of TIA1 gene in M2-TAMs can affect the inva-sion and migration of gastric cancer cells by blocking the PI3K/AKT signaling pathway.
