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.

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 investigate the effect of relaxing needling at the contracted sites of meridian-muscle regions in the patients with post-stroke shoulder-hand syndrome (SHS) at acute stage. METHODS: Eighty patients with post-stroke SHS at acute stage were randomized into an observation group (40 cases, 1 case dropped out) and a control group (40 cases, 1 case was eliminated). In the control group, the routine medication, basic rehabilitation training, and hyperbaric oxygen therapy were administered. In the observation group, besides the treatment as the control group, relaxing needling was delivered at the contracted sites of meridian-muscle regions. These contracted sites were distributed along three yin meridians of hand and three yang meridians of hand on the affected upper limbs. The intervention was given once daily, 5 times a week and for 4 weeks. Before and after treatment, the scores of visual analogue scale (VAS) for pain, edema degree, modified Barthel index (MBI), and Fugl-Meyer assessment (FMA) for motor function, and the integrated electromyography (iEMG) of surface electromyogram (sEMG) were observed in the two groups. The curative effect was evaluated after treatment and in follow-up of 2 months after treatment in the two groups. RESULTS: After treatment, VAS scores and the scores of edema degree were reduced when compared with those before treatment in the two groups (P<0.05), and the scores in the observation group were lower than those in the control group (P<0.05). MBI and FMA scores increased after treatment compared with those before treatment in the two groups (P<0.05), and the scores in the observation group were higher than those in the control group (P<0.05) after treatment. The iEMG values of the biceps brachii, triceps brachii, and wrist extensors were elevated after treatment in comparison with those before treatment (P<0.05) in the two groups, and the values in the observation group were larger than those in the control group after treatment (P<0.05). The total clinical effective rate in the observation group was 92.3% (36/39), which was better than that of the control group (74.4%, 29/39, P<0.05) after treatment; and that of the observation group was 97.4% (38/39), which was better than 82.1% (32/39) in the control group (P<0.05) in follow-up. CONCLUSION Relaxing needling at the contracted sites of meridian-muscle regions in treatment of post-stroke SHS at acute stage can attenuate the symptoms such as upper limb pain, swelling and spasm, improve motor function and the activity of daily living of patients.

Disruption of the intestinal mucosal barrier caused by gut dysbiosis and metabolic imbalance is the underlying pathology of inflammatory bowel disease (IBD). Traditional Chinese medicine Wuji Wan (WJW) is commonly used to treat digestive system disorders and showed therapeutic potential for IBD. In this interdisciplinary study, we aim to investigate the pharmacological effects of WJW against experimental colitis by combining functional metabolomics and gut-microbiota sequencing techniques. Treatment with WJW altered the profile of the intestinal microbiota and notably increased the abundance of Lactobacillus, thereby facilitating the conversion of tryptophan into indole-3-acetic acid (IAA) and indoleacrylic acid (IA). These indole derivatives activated the aryl hydrocarbon receptor (AhR) pathway, which reduced colonic inflammation and restored the expression of intestinal barrier proteins. Interestingly, the beneficial effects of WJW on gut barrier function improvement and tryptophan metabolism were disappeared in the absence of gut microbiota. Finally, pre-treatment with the AhR antagonist CH-223191 confirmed the essential role of IAA-mediated AhR activation in the therapeutic effects of WJW. Overall, WJW enhanced intestinal barrier function and reduced colonic inflammation in a murine colitis model by modulating Lactobacillus-IAA-AhR signaling pathway. This study provides novel insights into colitis pathogenesis and presents an effective therapeutic and preventive approach against IBD.

Objective To explore the efficacy and safety of antiplatelet therapy in patients with acute ischemic stroke(AIS)complicated with gastric cancer.Methods Clinical data of 89 patients with AIS complicated with gastric cancer who were hospitalized in the First People's Hospital of Huzhou from January 2018 to October 2022 were retrospectively analyzed.The patients were divided into treatment group(59 cases)and untreated group(30 cases)according to whether they received antiplatelet therapy or not,and the clinical characteristics and prognosis of the two groups were compared.To analyze the clinical features and influencing factors of gastrointestinal bleeding complicated by antiplatelet therapy in AIS patients with gastric cancer.Results The patients in treatment group were younger than those in untreated group,and had more history of antiplatelet therapy,hypertension and cardiovascular disease,the difference was statistically significant(P<0.05).The National Institute of Health stroke scale(NHISS)and modified Rankin scale(mRs)of patients in treatment group were lower than those in untreated group after antiplatelet therapy,the difference was statistically significant(P<0.05).The incidence of bleeding in treated group was significantly higher than that in untreated group(P<0.05),most of the patients had mild hemoglobin decline.Multivariate Logistic analysis suggested that chronic renal insufficiency,gastric cancer lesion diameter≥2cm and T1-T2 stage are risk factors for gastrointestinal bleeding in AIS patients with gastric cancer after taking aspirin for antiplatelet therapy.Conclusion In AIS patients with gastric cancer,aspirin antiplatelet therapy can effectively improve cerebrovascular function and reduce the degree of brain nerve damage.However,when these patients are combined with T1-T2 stage,chronic renal insufficiency and gastric cancer lesion diameter≥2cm,gastrointestinal bleeding is easy to occur.

Objective To detect the changes of serum microRNA-126(miR-126)before interventional thrombectomy for acute cerebral infarction,and to explore its correlation with the prognosis of patients.Methods A retrospective analysis was performed on 101 patients with cerebral infarction who underwent interventional thrombectomy in he First People's Hospital of Huzhou from January 2019 to December 2021.The patients were followed up for 2 month.According to modified Rankin scale(mRS),they were divided into good prognosis group(mRS≤2 points,56 cases)and poor prognosis group(mRS>2 points,45 cases).The clinical data of two groups and the difference of miR-126 before thrombectomy were compared,and the effect of serum miR-126 change on the prognosis of patients with cerebral infarction was analyzed.Results The serum miR-126 level before thromrectomy in good prognosis group was significantly higher than that in poor prognosis group[(9.31±2.14)vs.(1.36±0.28),P<0.01].There was a negative correlation between miR-126 and National Institute of Health stroke scale(NIHSS)score(r=-0.737,P<0.01),and a positive correlation between miR-126 and good collateral circulation(r=0.645,P<0.01).The area under the receiver operating characteristic curve for establishing miR-126 to predict prognosis after thrombolectomy for cerebral infarction was 0.818.The sensitivity and specificity were 78.9%and 86.0%at the optimal cut-off value.Conclusion The change of serum miR-126 level before thrombectomy may be related to the prognosis of patients with cerebral infarction,which can be used as a marker to predict the prognosis of cerebral infarction after interventional therapy.

Currently,human health due to corona virus disease 2019(COVID-19)pandemic has been seriously threatened.The coronavirus severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)spike(S)protein plays a crucial role in virus transmission and several S-based therapeutic approaches have been approved for the treatment of COVID-19.However,the efficacy is compromised by the SARS-CoV-2 evolvement and mutation.Here we report the SARS-CoV-2 S protein receptor-binding domain(RBD)inhibitor licorice-saponin A3(A3)could widely inhibit RBD of SARS-CoV-2 variants,including Beta,Delta,and Omicron BA.1,XBB and BQ1.1.Furthermore,A3 could potently inhibit SARS-CoV-2 Omicron virus in Vero E6 cells,with EC50 of 1.016 pM.The mechanism was related to binding with Y453 of RBD deter-mined by hydrogen-deuterium exchange mass spectrometry(HDX-MS)analysis combined with quan-tum mechanics/molecular mechanics(QM/MM)simulations.Interestingly,phosphoproteomics analysis and multi fluorescent immunohistochemistry(mIHC)respectively indicated that A3 also inhibits host inflammation by directly modulating the JNK and p38 mitogen-activated protein kinase(MAPK)path-ways and rebalancing the corresponding immune dysregulation.This work supports A3 as a promising broad-spectrum small molecule drug candidate for COVID-19.

Objective:To make an individual phantom that was printed by using three dimension(3D)technique,which could reflect the real situation of patient,and to analyze the computed tomography(CT)value and dose distribution of radiotherapy on each organ of the inside of the 3D-printed individual phantom.Methods:According to the localization of CT image of the patient,the empty shell of 3D structure of each organ were reconstructed and printed by using 3D technique.The CT value was used as basis to select the equivalent material of each organ to perform fill,which could obtain the individual phantom of chest that could appear the structural characteristics of patient.The treatment plan of patients were included in treatment plan group,and the plans which were transplanted to 3D-printed individual phantom from treatment plan of patients were included in phantom plan group.The dosimetric parameters of the plans of two groups were compared.Results:The average CT values of left and right lung,soft tissue,cancellous bone,compact bone and heart of the phantom plan group were respectively-709,-737,14,144,760 and 28 HU.The errors of the all CT values between phantom images and located images of patients were less than 16.7%.The exposure doses of normal tissues of radiotherapy plans on the images of two groups could meet the clinical requirements.The minimum dose(Dmin),mean dose(Dmean),the corresponding doses of 98%,50% and 2% target volumes(D98%,D50% and D2%),conformity index(CI),homogeneity index(HI),monitor unit(MU)of dosimetric parameters of the target region could meet the clinical requirements without statistically significant differences.There was significant differences in the maximum dose(Dmax)of the target region(t=2.678,P＜0.05).Among of these Dmax values,the Dmax value of phantom plan group was larger,which was(56.97±0.32)Gy.Conclusion:The CT value,tissue structure and spatial distribution of the phantom,which is finally designed,can emulate the chest of human body in radiotherapy.It has verified the feasibility that 3D-printed phantom is applied in measuring dose in the quality assurance of radiotherapy.

Objective:To investigate the correlation between the levels of CC chemokine ligand 2 (CCL2) and periostin (POSTN) in serum and alveolar lavage fluid of patients with acute exacerbation of chronic obstructive pulmonary disease (COPD) complicated with respiratory virus infection and lung function.Methods:From March 2020 to March 2023, 96 patients with acute exacerbation of COPD admitted to our hospital were collected. Among them, 34 patients with concurrent respiratory virus infection were included in the infected group, and 62 patients without respiratory virus infection were included in the uninfected group. Enzyme linked immunosorbent assay (ELISA) was applied to detect the expression levels of CCL2 and POSTN in serum and alveolar lavage fluid. Pearson method was applied to analyze the correlation between CCL2 and POSTN levels in serum and alveolar lavage fluid of infected patients and lung function indicators.Results:The levels of CCL 2 ( t=12.633, 9.253 2, 2) and POSTN ( t=12.370, 7.383) were significantly increased in the infected group compared with the uninfected group ( P<0.05). Compared with the uninfected group, the 6-minute walking test (6 MWT), peak expiratory flow rate (peak expiratory flow, PEF), forced expiratory volume at the first second (forced expiratory volume in one second, FEV 1), and the forced lung capacity (forced vital capacity, FVC), FEV 1/FVC, and maximum middle breath mean flow rate (maximal mid-expiratory flow curve, MMEF) were significantly lower ( t=14.141, 24.165, 22.421, 21.223, 5.278, 29.456, P<0.05). Correlation analysis showed that the levels of CCL2 and POSTN in the serum and alveolar lavage fluid of the infected group were negatively correlated with the levels of 6MWT, PEF, FEV1, FVC, FEV1/FVC, and MMEF ( P<0.05). Conclusions:CCL2 and POSTN levels were highly expressed in serum and alveolar lavage fluid of patients with respiratory virus infection during acute exacerbation of COPD, which were closely related to lung function.
