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 investigate the relationship between tooth loss and the occurrence of esophageal cancer in a natural village in Wenfeng District, Anyang City, Henan Province. Methods A prospective cohort study was conducted to observe the occurrence of tooth loss and esophageal cancer among the asymptomatic residents of the natural village for 16 years from January 2008 to July 2024. Data were analyzed by chi-square test, binary logistic regression, and restricted cubic spline. Results Among the total population of 711 cases, 136 cases were lost to follow-up and 575 cases were included in the final statistics, including 45 cases with esophageal cancer. Significant statistical difference was found between esophageal cancer patients with and without tooth loss (P<0.05). Logistic regression analysis showed that tooth loss was associated with the occurrence of esophageal cancer (OR=3.977, 95%CI: 1.543-10.255). After the adjustment for confounders, tooth loss remained significantly associated with the occurrence of esophageal cancer (OR=3.038, 95%CI: 1.035-8.914). A nonlinear dose-response relationship was observed between the number of teeth lost and the incidence of esophageal cancer. When the number of teeth lost was less than 12, the risk of esophageal cancer increased with the number of teeth lost. When more than 12 teeth were lost, the risk of esophageal cancer decreased as the number of teeth lost increased. Conclusion Tooth loss is a risk factor for the occurrence of esophageal cancer in this natural village. When the number of teeth lost is less than 12, the risk of esophageal cancer increases with the number of teeth lost.

ObjectiveTo analyze the drug resistance and the molecular typing characteristics through pulsed field gel electrophoresis (PFGE) of Campylobacter spp. isolated from patients with infectious diarrhea in Baoshan District of Shanghai, and to provide a basis for Campylobacter spp. prevention and control and clinical medication. MethodsCampylobacter spp. was isolated, cultured and identified from stool samples of diarrheal patients collected from medical institutions at two monitoring sites in Baoshan District from 2019 to 2022. Antimicrobial susceptibility testing for 12 antibiotics was conducted on the isolated Campylobacter jejuni (C. jejuni) and Campylobacter. Coli (C. coli), and molecular typing was performed using PFGE. ResultsA total of 179 strains of Campylobacter spp. were isolated from 1 786 samples of diarrheal patients, with a positive rate of 10.02%. The highest resistance rate of C. jejuni was to ciprofloxacin (98.63%), followed by tetracycline (97.26%) and nalidixic acid (89.73%). C. coli was completely resistant to ciprofloxacin and nalidixic acid (100.00%), followed by tetracycline (90.91%). The multidrug resistance rates of C. jejuni and C. coli were 89.73% and 100.00%, respectively. 142 strains of C. jejuni produced 122 PFGE bands, while 33 strains of C. coli produced 33 PFGE bands, and the distribution of the bands was relatively dispersed. ConclusionFrom 2019 to 2022, the detection rate of Campylobacter in diarrheal patients was relatively high in Baoshan District of Shanghai, the multidrug resistance rate of Campylobacter isolates from diarrheal patients was relatively serious, in addition, the drug resistance pattern was complex, and the PFGE band pattern displayed a polymorphic distribution.

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.

The developmental origins of health and disease(DOHaD)suggests that a poor maternal developmental environment during pregnancy can significantly increase the risk of chronic metabolic diseases such as obesity,diabetes mellitus(DM),and cardiovascular disease in offspring during adulthood.The adverse environmental factors of the father's generation influence the glucose and lipid metabolism of the offspring.The environmental factors exposed by the father before fertilization,such as over nutrition,obesity,diabetes caused cross generation reprogramming in offspring,and develop glucose and lipid metabolism disorders,which can last for one or more generations.Currently,paternal origin of health and disease(POHaD)has received widespread attention and has important scientific value and social significance.This article reviews the research progress on the impact of parental nutritional environment on offspring glucose metabolism.

BACKGROUND:It is of great significance to find new diagnostic markers of the disease and molecular targets for the treatment of the disease and the alleviation of organ injury.Ferroptosis is a newly discovered form of cell death.Overactivation of ferroptosis in animal models of sepsis is associated with the activation of inflammatory response and the injury of the liver,heart,kidney and other important organs,but the relationship between ferroptosis and bloodstream infection is not very clear. OBJECTIVE:To study the changes and biological significance of ferroptosis in a mouse model of blood stream infection induced by different bacteria. METHODS:Blood stream infection models induced by gram negative bacteria Escherichia coli,Klebsiella pneumoniae and gram positive bacteria Staphylococcus aureus and Enterococcus faecalis were established in SPF-grade ICR male mice,with 42 mice in each group.The mRNA expression levels of ferroptosis marker genes transferrin receptor 1 and glutathione peroxidase 4 in the liver,myocardium and kidney were detected at 0.5,1,3,6,12,24 and 48 hours after modeling.Another 18 SPF-grade ICR male mice were selected and randomly divided into dimethyl sulfoxide(DMSO)control group,DMSO+Klebsiella pneumoniae group,and Ferrostatin-1+Klebsiella pneumoniae group,with 6 mice in each group.In the latter two groups,animal models of Klebsiella pneumoniae bloodstream infection were established by tail vein injection of Klebsiella pneumoniae suspension,and 5 mg/kg Ferrostatin-1 and an equal dose of DMSO were given intraperitoneally 1 hour prior to the modeling of bloodstream infection,respectively.Serum levels of alanine aminotransferase,aspartate aminotransferase,blood creatinine,blood urea nitrogen,phosphocreatine kinase isoenzyme,lactate dehydrogenase,and mRNA expression levels of ferroptosis marker genes in various tissues were assayed at 6 hours after modeling. RESULTS AND CONCLUSION:After bloodstream infection modeling,the mRNA expression levels of transferrin receptor 1 in the liver,myocardium and kidney of bloodstream infection mice with different bacteria increased first and then decreased;and the mRNA expression level of glutathione peroxidase 4 decreased first,then increased,and reached the peak at 6 hours after modeling.The changes in transferrin receptor 1 and glutathione peroxidase 4 mRNA levels in bloodstream infection mice induced by gram-negative bacteria were more significant than those in blood stream infection mice induced by gram-positive bacteria,especially in bloodstream infection mice induced by Klebsiella pneumoniae.At 6 hours after bloodstream infection induced by Klebsiella pneumoniae,the levels of alanine aminotransferase,aspartate aminotransferase,serum creatinine,blood urea nitrogen,creatine phosphate kinase isoenzyme,lactate dehydrogenase in mice were significantly increased.Before modeling,Ferrostatin-1 intervention significantly reduced the levels of alanine aminotransferase,aspartate aminotransferase,serum creatinine,blood urea nitrogen,creatine phosphate kinase isoenzyme,and lactate dehydrogenase.All these findings indicate that the activation of ferroptosis in bloodstream infection mice induced by different bacteria is obvious,and the activation of ferroptosis in bloodstream infection mice induced by gram-negative bacteria is more obvious.Inhibition of iron death significantly attenuates liver,myocardial,and kidney injury in the mouse model of bloodstream infection induced by Klebsiella pneumoniae.

The objective was to report a relatively rare case of fulminant type 1 diabetes(FT1 DM)complicated with acute pancreatitis(AP),to summarize the characteristics as well as experience of diag-nosis and treatment,and to explore its pathogenesis.Clinical data of a case of FT1DM complicated with AP in the Department of Endocrinology of our hospital were analyzed retrospectively.A 66-year-old male presented with acute fever and abdominal pain,accompanying with the significantly elevated pancreatic enzymes,and his abdominal CT scan showed exudation around the pancreas.The clinical manifestations mentioned above were consistent with the diagnosis of AP.Five days after onset,the patient developed clinical symptoms,such as obvious thirst,polyuria,polyasthenia and fatigue.Meanwhile,his plasma glucose increased significantly and the diabetic ketoacidosis(DKA)occurred.The patient's fasting and postprandial 2 hours C peptide decreased significantly(all 0.02 μg/L),glycated hemoglobin level was not high(6％),and his islet-related autoantibodies were undetectable.Thus,the patient could be diag-nosed with FT1DM.After the treatment of fasting,fluid replacement,anti-infection,somatostatin,anti-coagulation and intravenous insulin sequential subcutaneous insulin pump,the patient gained the allevia-tion of pancreatitis,restoration of oral intake,and relatively stable blood glucose levels.Summarizing the characte-ristics of this case and reviewing the literature,FT1DM complicated with AP was relatively rare in FT1DM.Its common characteristics were described below:(1)Most cases started with AP and the blood glucose elevated within 1 week,or some cases had the simultaneously onset of AP and FT1DM.(2)The clinical course of AP was short and relieved no more than 1 week;Pancreatic imaging could completely return to normal within 1 to 4 weeks after onset.(3)The etiology of AP most was idiopathic;The elevation of pancreatic enzyme level was slight and the recovery was rapidly compared with AP of other etiologies.FT1DM could be complicated with AP,which was different from the physiological mani-festations of pancreatic disease in general FT1DM patients.Virus infection mignt be the common cause of AP and FT1DM,and AP might be the early clinical manifestation of some FT1DM.The FT1DM patients developed with abdominal pain was easy to be missed,misdiagnosed and delayed,which should receive more attention in clinic.

Background and objective Isoliquiritigenin(ISL)is an important pharmacological constituent of Glycyrrhiza glabra,which possesses a range of physiological and pharmacological activities,as well as significant antitumor ac-tivity,and can be used as a potential drug for targeted cancer therapy.LINC01503 is an oncogene,which has been closely asso-ciated with the malignant biological processes of many cancers.The aim of this study was to investigate the effects of ISL on the proliferation,apoptosis,invasion and migration oflung squamous carcinoma cells by regulating LINC01503.Methods Plasma was collected from lung squamous carcinoma patients and healthy individuals treated at Tangshan People's Hospital from Janu-ary 2021 to December 2022.The expression of LINC01503 in lung squamous carcinoma plasma,tissues and cells was detected by real-time quantitative fluorescence polymerase chain reaction(qRT-PCR).Lung squamous carcinoma cells were treated with different concentrations of ISL for 24 h,and LINC01503 expression was detected by qRT-PCR.The cells were treated in groups:si-NC group,si-LINC01503 group,DMSO(0.1％dimethyl sulfone)group,ISL group,pc DNA3.1(+)-NC group,pc DNA3.1(+)-LINC01503 group,ISL+pc DNA3.1(+)-NC group and ISL+pc DNA3.1(+)-LINC01503 groups.CCK-8 assay,clone formation assay,flow cytometry,Transwell assay and scratch assay were used to explore the effect of LINC01503 on the functional phenotype of lung squamous carcinoma cells.Results Fluorescence in situ hybridization results showed that the average fluorescence intensity of LINC01503 in tissue microarrays of lung squamous carcinoma patients was higher than that in paracancerous tissues(P＜0.05).The expression of LINC01503 in the plasma of patients with lung squamous carcinoma was higher than that in the plasma of healthy individuals(P＜0.05).Knockdown of LINC01503 inhibited the proliferation,invasion and migration of lung squamous carcinoma cells and promoted apoptosis(P＜0.05).ISL inhibited the proliferation,invasion,migration and promoted apoptosis of lung squamous carcinoma cells(P＜0.05).Overexpression of LINC01503 followed by intervention with ISL reversed the promotional effect of overexpression of LINC01503 on the proliferation,invasion and migration of lung squamous carcinoma cells as well as the inhibitory effect on apoptosis(P＜0.05).Conclusion LINC01503 was highly expressed in lung squamous carcinoma,and LINC01503 could promote the proliferation,invasion and migra-tion of lung squamous carcinoma cells and inhibit the apoptosis,ISL could inhibit the proliferation,invasion and migration of lung squamous carcinoma cells and promote apoptosis of lung squamous carcinoma cells by regulating the expression of LINC01503.

Objective:To explore the application and clinical efficacy of functional neural navigation multimodal image fusion technology combined with intraoperative fluorescein sodium in the surgery of lung cancer brain metastases.Methods:Forty patients with lung cancer and brain metastasis admitted to the Department of Neurosurgery of Inner Mongolia Autonomous Region People's Hospital from January 2020 to January 2024 were collected as the observation group. Another 40 patients with lung cancer brain metastases who underwent microscopic resection at Inner Mongolia Autonomous Region People's Hospital from January 2016 to December 2019 were selected as the control group. All patients received head CT examination, head MRI examination, MRI enhanced sequence and MRA, MRV and DWI sequence scanning before operation. Functional neural navigation system was used to perform preoperative multi-modal image fusion to realize three-dimensional display of tumor lesions, and display the position relationship between tumor and functional areas, conduction bundles and large blood vessels, so as to make preoperative navigation plan. After conducting a fluorescein sodium allergy test on the patient before surgery, a small dose of fluorescein sodium (2 mg/kg) was intravenously injected during the operation. During the operation, neuro navigation was combined with fluorescein sodium to perform tumor resection by displaying the boundary between tumor tissue and normal brain tissue under a Pentero 900 Zeiss microscope 560 fluorescence mode. Both groups collected tumor tissue samples for pathological classification and immunohistochemical analysis, comparing and analyzing differences in tumor resection degree, postoperative occurrence of new neurological dysfunction, postoperative muscle strength improvement, changes in KPS scores before and after surgery, and the occurrence of complications. The metric data that conforms to normal distribution is represented by xˉ± s, and the comparison of means between two groups is conducted using independent sample t-test. Calculate the percentage based on the count data, and compare the inter group rates using the χ2 test. P<0.05 indicates statistical significance of the difference. Results:Compared with the control group, the total tumor resection rate of observation group (75.0% (30/40) ) and KPS score of 3 months after surgery (82.5% (33/40)) were better than those of the control group (52.5% (21/40) and 60% (24/40)), and the differences were statistically significant ( χ2 value was 4.94 and 4.38, P values were 0.026 and 0.036). The rate of postoperative new neurological dysfunction in the observation group (22.5% (9/40)) was lower than that in the control group (45.0% (18/40)), and the difference between the two groups was statistically significant ( χ2=4.53, P=0.033). The length of hospital stay ((21.48±3.23) days), operation time ((216.65±56.76) points) and complication rate (37.5% (15/40)) in observation group were lower than those in control group ((22.43±2.34) days, (225.62±37.68) points, 45.0% (18/40)). However, the difference was not statistically significant ( t/ χ2 values were 1.51, 0.83, and 0.46, respectively; P values were 0.136, 0.408, and 0.496, respectively). The 12-month survival rate of observation group (67.5%(27/45) respectively was significantly higher than that of control group (40.0%(16/40) respectively, and the difference was statistically significant ( χ2=6.08, P=0.014). Conclusion:Functional neural navigation multimodal image fusion technology combined with intraoperative fluorescein sodium can accurately locate the tumor and determine the boundary relationship between the tumor and normal brain tissue during lung cancer brain metastasis surgery, improve tumor resection rate, enhance patient quality of life, and ultimately improve patient prognosis without increasing the risk of related complications.

Objective:To explore the clinical manifestations and characteristics of serum adrenal cortex hormone spectrum in patients with adrenocortical hypercortisolism with different pathological types of adrenal adenoma.Methods:A retrospective analysis was conducted on 68 patients with adrenal Cushing's syndrome who underwent surgical treatment in the Department of Endocrinology and/or Urology, Peking University First Hospital from January 2018 to June 2022. Among them, 12 patients had obvious eosinophilic changes in pathology(eosinophilic group), and 56 patients had no obvious eosinophilic changes(non-eosinophilic group). Among eosinophilic group, one male and 11 females, age(49.83±9.87) years old, body mass index (BMI)(25.86±3.21) kg/m 2, systolic blood pressure (140.25±20.72)mmHg(1 mmHg=0.133 kPa), diastolic blood pressure(91.00±14.87)mmHg, 7 cases were overt Cushing's syndrome.

There was no statistically significant difference in the above indicators between the two groups ( P>0.05).In terms of laboratory tests, 0: 00 cortisol levels in the eosinophilic group and non-eosinophilic groups were 14.95(5.93, 23.2) ng/dl and 6.69(4.07, 11.35) ng/dl ( P=0.044), the cortisol levels after 1mg dexamethasone inhibition test were 20.19(11.29, 26.92) ng/dl and 5.94(2.68, 12.90) ng/dl ( P=0.005), and 8: 00, 16: 00, and 0: 00, ACTH levels were 2.08 (1.02, 2.90) pg/ml and 8.37(2.30, 11.67) pg/ml ( P=0.006), 1.22(1.00, 3.20) pg/ml, and 4.22(1.80, 6.33) pg/ml ( P=0.012), 0.65 (0, 2.63) pg/ml, and 2.76(1.44, 5.57) pg/ml( P=0.023), serum triglyceride were 1.92(1.31, 2.50) mmol/L and 1.31(1.04, 1.80) mmol/L ( P=0.026), and the differences were statistically significant. In terms of target organ damage, there were 6 cases and 10 cases ( P=0.017) in the eosinophilic group and non eosinophilic group with ventricular wall hypertrophy, 1 case and 0 cases( P=0.030) in the aortic dissection group, and 4 cases and 5 cases ( P=0.024) with four or more types of target organ damage, respectively, with statistically significant differences. Two groups of preoperative serum adrenal cortex hormone profiles were detected by liquid chromatography tandem mass spectrometry. The differences in adrenal cortex hormone profiles and hormone ratios between the two groups were compared. Age, gender, and statistically significant indicators were included in a multivariate logistic regression model to analyze the correlation between each indicator and eosinophilic changes. Results:Adrenal cortical hormone profile of the two groups showed that the serum estrone levels in the eosinophilic group and non-eosinophilic group were 20.27(13.49, 39.81) pg/ml and 12.59(8.08, 21.18) pg/ml ( P=0.034), and 11-hydroxyandrostenedione levels were 692.34(536.19, 1 049.66) pg/ml and 1 157.60(710.78, 1 539.30) pg/ml( P=0.026), with statistically significant differences; There were no statistically significant difference in the expression levels of other hormones ( P>0.05). In terms of hormone ratio, the estradiol/testosterone ratios in the eosinophilic and non eosinophilic groups were 0.14(0.08, 0.62) and 0.04(0.01, 0.09)( P=0.008), the estrone/androstenedione ratios were 0.06(0.05, 0.12) and 0.04(0.03, 0.06)( P=0.007), the 11-hydroxyandrostenedione/androstenedione ratios were 2.26(1.30, 2.69) and 4.03(2.48, 5.25)( P=0.008), the estriol/estrone ratios were 0.10(0.03, 0.29) and 0.25(0.12, 0.51)( P=0.016), the estriol/estradiol were 0.22(0.03, 0.30) and 0.33(0.12, 0.73)( P=0.032), and the differences were statistically significant. The results of multivariate analysis showed that estrone ( OR=1.04, 95% CI 1.01-1.07, P=0.009) and estrone/androstenedione ( OR=25 008 670.29, 95% CI 8.45-74 015 852 572 024.10, P=0.025) were independently associated with eosinophilic pathology. Conclusions:Adrenocortical hypercortisolism patients with eosinophilic pathology have higher levels of serum cortisol secretion, more pronounced inhibition of the hypothalamic pituitary adrenal axis, more significant metabolic disorders and target organ damage, and higher production of estrone.
