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 value of serum cell cycle protein-dependent kinase 1(CDK1)and aurora kinase A(AURKA)in the diagnosis of patients with hepatitis B virus-related hepatocellular carcinoma(HBV-HCC).Methods A total of 50 HBV-HCC patients,50 patients with hepatitis B virus-related liver cirrhosis(HBV-LC),and 50 chronic hepatitis B(CHB)patients who were hospitalized in Department of Gastroenterology,Gansu Provincial Hospital,from June 2022 to December 2023 were enrolled,and 50 healthy individuals,matched for age and sex,who received physical examination at Physical Examination Center during the same period of time were enrolled as control group.Related data were recorded for all patients,including age,sex,complications,and the results of routine blood test,liver function,and coagulation for the first time after admission.ELISA was used to measure the serum levels of CDK1 and AURKA.A one-way analysis of variance was used for comparison of normally distributed continuous data between multiple groups,and the least significant difference t-test was used for further comparison between two groups;the Kruskal-Wallis H test was used for comparison of non-normally distributed continuous data between multiple groups and the least significant difference Bonferroni test was used for further comparison between two groups;the chi-square test or the Fisher's exact test was used for comparison of categorical data between groups.The Spearman correlation analysis was used to investigate the correlation between CDK1 and AURKA,and the receiver operating characteristic(ROC)curve and the area under the ROC curve(AUC)were used to investigate the value of CDK1 and AURKA in the diagnosis of HBV-HCC.Results There were significant differences in liver function parameters between the HBV-HCC patients and the control group(all P<0.05);there were significant differences between the CHB group and the HBV-HCC group in albumin,Glb,direct bilirubin,aspartate aminotransferase(AST),gamma-glutamyl transpeptidase(GGT),and alkaline phosphatase(all P<0.05);there were significant differences between the HBV-LC group and the HBV-HCC group in Glb,AST,and GGT(all P<0.05).The HBV-HCC group had significantly higher serum levels of CDK1 and AURKA than the HBV-LC group,the CHB group,and the control group(all P<0.05).There was a significant positive correlation between CDK1 and AURKA in the overall study population and the HBV-HCC patients(r=0.526 6 and 0.815 2,P<0.001).With the control group as reference,CDK1 had an AUC of 0.832 3 in the diagnosis of HBV-HCC,with a sensitivity of 92.86%and a specificity of 75%,and AURKA had an AUC of 0.886 6 in the diagnosis of HCC,with a sensitivity of 95.80%and a specificity of 74%.With the CHB group as reference,CDK1 had an AUC of 0.833 3 in the diagnosis of HBV-HCC,with a sensitivity of 93.75%and a specificity of 75%,and AURKA had an AUC of 0.972 7 in the diagnosis of HBV-HCC,with a sensitivity of 95.83%and a specificity of 91.67%.With the HBV-LC group as reference,CDK1 had an AUC of 0.608 5 in the diagnosis of HBV-HCC,with a sensitivity of 66.67%and a specificity of 54.17%,and AURKA had an AUC of 0.762 2 in the diagnosis of HBV-HCC,with a sensitivity of 95.83%and a specificity of 47.92%.Conclusion The serum levels of CDK1 and AURKA increase with the progression of hepatitis B-associated chronic liver disease,and significant increases in serum CDK1 and AURKA have a certain value in the diagnosis of HBV-HCC.

Objective:To explore the association between the intake and changes in various types of food and the changes in blood pressure in patients with mild to moderate hypertension.Methods:Mild to moderate hypertension participants with complete baseline and outcome data were included from DECIDE-Diet study, a multicenter, randomized controlled trial. Dietary records and blood pressure measurements at both 7-day run-in (baseline) and 28-day intervention phases were collected for enrolled participants. Blood pressure change was defined as the difference between blood pressure at the end of trial and the baseline blood pressure. Baseline intake of food was the average daily intake during the run-in period, and the intake increment was defined as the difference between the average intake during the trial period and the average intake during the run-in period. After adjusting for age, sex, study center, intervention groups, baseline body mass index (kg/m 2), antihypertension medication use, and baseline total calorie intake, a linear regression model was used to analyze the associations of the before-after-intervention change in blood pressure with baseline intake and intake increment of foods. Results:A total of 258 patients with mild to moderate hypertension were included, including 133 males, aged (56.5±9.9) years. (1) After adjusting for confounding factors, there was no significant association between baseline intake of food and baseline blood pressure (all P>0.05). The blood pressure change was negatively associated with baseline intakes of tubers, vegetables, and vegetable oils but positively with baseline intake of meats; and was negatively associated with intake increment of whole grains and fish (all P<0.05). (2) The multiple linear regression analysis showed that baseline intake of vegetables ( β=-0.021, P=0.004), vegetable oils ( β=-0.260, P=0.002), and increment in intake of fish ( β=-0.128, P=0.026) were all significantly associated with changes in systolic blood pressure; baseline intake of vegetables ( β=-0.017, P=0.002), vegetable oils ( β=-0.182, P=0.001), dairy products ( β=0.021, P=0.022), and increment in intake of fish ( β=-0.092, P=0.010) were all significantly associated with changes in diastolic blood pressure. Conclusion:Increasing the intake of whole grains, vegetables, vegetable oils, and fish and decreasing the intake of meat may be beneficial for blood pressure control in patients with mild to moderate hypertension.

Objective:To investigate the clinical effect of progressive transfer of penile flap combined with local scrotal flap in correction of severe concealed penis in children.Methods:The clinical data of children with severe concealed penis admitted to the Children’s Hospital Affiliated to Zhengzhou University from July 2021 to July 2023 were retrospectively analyzed. The concealed penis was corrected by progressive transfer of penile flap combined with local scrotal flap. During the operation, a small amount of excess inner prepuce was removed and the outer prepuce was cut in the middle of the dorsal side of the penis. Then the penile flap was transferred from dorsal to ventral, gradually covering the wound without tension. The local scrotal flap was lifted upwards and sutured to the frenulum for covering the ventral foreskin defect of the penis. The amount of blood loss during the operation was recorded. The pain tolerance, the duration of prepuce edema, the length of penis extension and the healing of skin flap were observed. The appearance of the penis was followed up to observe whether the penis was retracted, and the satisfaction of the children and their guardians was recorded.Results:A total of 32 male children were enrolled, ranging in age from 3 to 10 years, with an average age of 7.2 years. The penis of all the children had a conical appearance, and the penile shaft was buried under the subcutaneous anterior pubis, which was difficult to palpate in its natural state. The average intraoperative blood loss was about 5 ml. All patients had pain after the operation. Two patients needed a pump to relieve pain, and the rest could tolerate it after rectum administration of indomethacin suppositories. The edema of the prepuce was mild after the operation, and the edema basically disappeared when the patient was discharged 7-9 days later. The penis could be lengthened by 1.5-3.0 cm under static conditions, averaging about 2.0 cm. After surgery, only 1 patient had a small area (about 5 mm × 4 mm) of infection in the scrotal flap and poor incision healing, and scar healing after dressing change and intensive nursing. The other flaps healed well. After 6 to 12 months of follow-up, the penis length of 2 cases was slightly retracted from the time of discharge, and the remaining 30 cases had no significant change. The patients and their guardians were satisfied with the operation results.Conclusion:The progressive transfer of penile flap combined with local scrotal flap correction of severe concealed penis in children can fully lengthen the penile body, and the degree of postoperative retraction is low, the appearance of the penis is good, and the patient satisfaction is high.

Objective:To analyze the epidemiological distribution characteristics, influencing factors, and infection rates of pertussis in the population of Henan Province.Methods:From 2022 to 2023, a cross-sectional survey was conducted to investigate the permanent population in Henan Province. Enzyme-linked immunosorbent assay (ELISA) was used to detect anti-pertussis toxin IgG (PT-IgG), analyze the antibody positivity rate (≥20 IU/ml) and median concentration (MC), and estimate the pertussis infection rate based on PT IgG ≥40 IU/ml. The rank sum test was used to compare antibody levels among groups, and the χ2 test was used to compare antibody positive rates and infection rates among groups. Results:A total of 4 810 research subjects were included in this study. The overall positive rate of PT-IgG was 12.10% and MC was 3.04 (0.35, 10.36) IU/ml. There were significant differences both in positive rates and antibody levels of PT-IgG among different regions or age groups (region positive rate: χ2=134.06, P<0.001, MC: H=337.74, P<0.001; age group positive rate: χ2=45.27, P<0.001, MC: H=134.49, P<0.001). Both the positive rate of PT-IgG (25.26%) and MC (8.01 IU/ml) were the highest within one year after completing a full course of vaccination. There were significant differences in positive rates and antibody levels among people receiving different types of pertussis vaccines (positive rate: χ2=12.38, P=0.006, MC: H=17.93, P<0.001). The antibody positivity rate (35.71%) and MC (8.88 IU/ml) of the people who received cell-free pertussis inactivated poliomyelitis influenza type b (combined) vaccine throughout the course were higher than those who received other types of vaccines. The natural infection rate of pertussis was evaluated for individuals aged≥3 years who had no history of pertussis vaccine immunization within the year prior to sampling. With a high vaccination rate, the estimated infection rate of pertussis in the population was 5 757.22/100 000. The infection rates in the 3-year-old (1 940.16/100 000) and 4-year-old (1 765.68/100 000) populations were at a low level among the entire population, reaching their peak at the age of 6 (12 656.71/100 000). Subsequently, although the infection rate continued to decline, it remained at a high level and peaked again at the age of 40-49 years (8 740.39/100 000). There was a statistically significant difference in the estimated infection rate of pertussis among different age groups ( χ2=53.21, P<0.001). Conclusion:The PT-IgG level of pertussis in the population of Henan Province is generally at a low level. The estimated infection rate of pertussis is much higher than the reported incidence rate. A booster dose of pertussis vaccine is recommended at 6 years old.

Glioma is the most common primary central nervous system tumor,mainly derived from glial cells,with strong invasiveness,easy recurrence,and poor prognosis.Glioblastoma is a high-grade glioma with the highest degree of malignancy.The clinical treatment method is mainly surgical resection,supplemented by compre-hensive treatment such as radiotherapy,chemotherapy,and electric field therapy,but the treatment effect is not satisfactory.In recent years,with the rapid development of the field of tumor immunotherapy,CD73 is a novel immune checkpoint related to adenosine metabolism,which can promote tumor progression by inhibiting anti-tumor immune responses and promoting angiogenesis.This article systematically reviews the mechanism of action of CD73 and discusses its biological role and application in glioma,aiming to provide potential treatment options for glioma patients.
