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 investigate the correlation between serum Chemerin and nerve growth associated protein (GAP) -43 levels and hyperhomocysteinemia (HHcy) in acute ischemic stroke.Methods:The clinical data of 149 patients with acute ischemic stroke admitted to the Sun Simiao Hospital of Beijing University of Traditional Chinese Medicine from March 2021 to May 2023 were retrospectively analyzed, and the patients were divided into observation group (97 cases) and control group (52 cases) according to whether they were combined with HHcy. Observation group patients were divided into mild group ( n=29), moderate group ( n=38) and severe group ( n=30) according to the severity of the disease. The serum Chemerin and GAP-43 levels of the observation group and the control group were compared, and the serum Chemerin and GAP-43 levels of the observation group with different severity of disease were compared, and the correlation between the serum Chemerin and GAP-43 levels and the severity of acute ischemic stroke patients with HHcy was analyzed. The influencing factors of poor prognosis in patients with acute ischemic stroke complicated with HHcy were analyzed, and receiver operating characteristic (ROC) curve was drawn to analyze the predictive value of serum Chemerin and GAP-43 for poor prognosis in patients with acute ischemic stroke complicated with HHcy. Results:The levels of Chemerin and GAP-43 in the observation group were higher than those in the control group (all P<0.05). Serum Chemerin and GAP-43 levels in the severe group were higher than those in the mild group and the moderate group (all P<0.05), and serum Chemerin and GAP-43 levels in the moderate group were higher than those in the mild group (all P<0.05). Pearson correlation analysis showed that serum Chemerin and GAP-3 levels were positively correlated with the severity of acute ischemic stroke patients with HHcy ( r=0.458, 0.497, all P<0.05). Among 97 patients with acute ischemic stroke complicated with HHcy, 19 had poor prognosis and 78 had good prognosis. In the poor prognosis group, the proportion of diabetes, the severity of the disease and the levels of blood glucose, C-reactive protein (CRP), vascular endothelial growth factor (VEGF) and malondialdehyde (MDA) were higher than those in the good prognosis group (all P<0.05), and the superoxide dismutase (SOD) was lower than those in the good prognosis group ( P<0.05). Logistic regression analysis showed that the severity of the disease, CRP, Chemerin and GAP-43 were the influential factors for the poor prognosis of acute ischemic stroke patients with HHcy (all P<0.05). ROC curve results showed that the area under the curve (AUC) of serum Chemerin and GAP-43 levels and their combination in predicting poor prognosis of acute ischemic stroke patients with HHcy were 0.799, 0.804 and 0.907, respectively, and the AUC of the combination was larger ( P<0.05). Conclusions:Serum Chemerin and GAP-43 levels are closely related to the severity and prognosis of acute ischemic stroke patients with HHcy, and their combined value is higher in predicting poor prognosis.

The "golden hour" strategy is an important measure to improve the short-term and long-term prognosis of neonates.It refers to optimizing interventions within one hour after birth, including neonatal resuscitation, transportation and early active treatment measures.Preterm birth and its complications are one of the main causes of neonatal death.Studies about "golden hour" strategy in premature infants have confirmed that it can increase the early stability, reduce complications and improve prognosis of preterm infants.This article reviews recent progress of "golden hour" in preterm infants and provide more information about quality improvement in premature infants care.

Emergency transport of critically ill neonates is an important means to reduce neonatal mortality and improve prognosis.Neonatal transport score is used to evaluate the safety of transport, mainly including transport risk index of physiologic stability, mortality index for neonatal transportation, transport related mortality score and intrauterine transport score.Evaluating the severity of disease of critically ill newborns before, during and after transport can reduce the occurrence of transport complications, reduce neonatal mortality, improve prognosis and increase the success rate of treatment.This paper reviews the research progress of critical neonatal transport scoring at home and abroad to help clinicians choose appropriate scoring methods according to specific conditions, in order to provide a basis for continuous quality improvement in this field.

Objective:To investigate the adhesion of polydopamine-modified collagen membrane composites to cartilage tissues and the effect on chondrocyte proliferation, and further explore the possibility of their application in autologous chondrocyte transplantation.Methods:Porous collagen membranes were prepared, and the polydopamine-modified collagen membrane composites were constructed by the adsorption method. The physical and chemical properties and structural characteristics of the membranes, such as thermal stability, thermal properties, porous structure, and surface element composition, were characterized by infrared spectroscopy, thermogravimetric analysis, differential thermal analysis, scanning electron microscopy, and X-ray photoelectron spectroscopy, respectively. The adhesion between the polydopamine-modified collagen membrane and fresh cartilage tissue was tested by a mechanical testing machine. The effects of the membranes on the adhesion and proliferation of rabbit chondrocytes were investigated by in vitro cell culture.Results:The structure and surface element composition of the membranes altered with the increase in the adsorption time of polydopamine, and the capacity of polydopamine increased with the increase in the adsorption time. The thermal stability and thermal properties of collagen membrane materials were not significantly affected by the adsorption of polydopamine. The adhesion of the membrane to cartilage tissue increased with the increase in the amount of absorbed polydopamine. The membranes showed a time-dependent promoting effect on the proliferation of the chondrocytes.Conclusions:The polydopamine-modified collagen membrane has potential application in articular cartilage repair, but more research is required to optimize the membrane before it is used in articular cartilage repair.

Objective:To investigate the efficacy and safety of peritoneal dialysis (PD) in end-stage renal disease (ESRD) patients with liver cirrhosis (LC).Methods:Clinical data of PD patients receiving regular treatment followed up for≥6 months, and aged≥18 years in the Third Affiliated Hospital of Hebei Medical University Peritoneal Dialysis Center from January 1, 2013 to March 31, 2020 were retrospectively collected. The patients were divided into LC-PD group and non-LC-PD group according to whether they had LC or not. Propensity score matching (PSM) was used to match the LC-PD group and the non-LC-PD group with 1∶4 ratio. The baseline clinical data, dialysis adequacy, peritonitis and clinical outcomes between the two groups were compared. Kaplan-Meier survival curve and Log-rank test were used to compare the survival rate and technical survival rate between the two groups.Results:A total of 241 PD patients were included in this study. After PSM, 13 cases in LC-PD group and 52 cases in non-LC-PD group were included. Compared with non-LC-PD group, patients in LC-PD group had lower baseline urine volume ( Z=-3.546, P<0.001) and serum albumin ( Z=-2.609, P=0.009). At the follow-up of 3, 6, 12 and 24 months, total serum protein ( t=-3.319, P=0.002), serum albumin ( t=-4.019, P<0.001), triglyceride ( Z=-2.263, P=0.024), and serum phosphorus ( Z=-2.173, P=0.030) in the LC-PD group were lower than those in non-LC-PD group. During the follow-up period of 2 years, the patients in the LC-PD group had significantly higher serum albumin than baseline values ( χ2=16.901, P=0.001), and there was no statistically significant difference between the two groups ( χ2=0.155, P=0.694). The decline rate of residual kidney Kt/V in the LC-PD group was slower than that in the non-LC-PD group ( χ2=44.589, P<0.001). The incidence of peritonitis in LC-PD group was higher than that in the non-LC-PD group, with a statistically significant difference (0.59/patient-year vs 0.20/patient-year, Z=-2.135, P=0.033). The composition ratio of pathogenic bacteria in both groups was mainly gram-positive bacteria (10/25 vs 11/30) and proportion of Streptococcus in LC-PD group was higher than that in non-LC-PD group (4/10 vs 0/11, P=0.035). The proportion of Escherichia coli in the first peritonitis was higher than that in LC-PD group (4/9 vs 1/22, P=0.017). The Kaplan-Meier survival curve results showed no statistically significant difference in survival rate (Log-rank χ2=0.491, P=0.484) and technical survival rate (Log-rank χ2=0.408, P=0.523) between the two groups. Conclusions:PD is a safe and effective treatment mode for ESRD patients with LC, and the survival rate and technical survival rate are comparable to those patients without LC. The incidence of peritonitis in patients with LC-PD in our dialysis center is higher than that in the non-LC-PD patients, and gram-positive bacterial infections are the mainstay, suggesting that attention should be paid to strengthening patient management and training.

ObjectiveTo study the conceptual framework and methodological system of the International Classification of Functioning, Disability and Health (ICF) in occupational therapy and its systematic implementation in clinical practice. MethodsBased on the ICF theory and the policy documents of the World Federation of Occupational Therapists, the conceptual framework of occupational therapy and the systematic implementation in clinical settings based on the ICF framework were analyzed. ResultsThis study constructed a conceptual framework and approach for occupational therapy based on ICF, and clarified the goals, principles, and implementation methods of integrated occupational therapy interventions in rehabilitation services. The goal of occupational therapy interventions was to improve the individual activity and participation through multidisciplinary and cross-cutting implementation of integrated occupational therapy programs to optimize functioning. Occupational therapy was based on the bio-psycho-social model, adhered to the principles of person-centeredness and functioning orientation, and implemented individualized intervention programs in different context. In clinical practice, it was recommended to follow ICF-based standardized process and systematically use World Health Organization Family International Classifications: functioning and unmet needs analysis using ICHI; functional classification, assessment and coding using ICF; disease classification, diagnosis and coding using ICD; intervention of occupational therapies using ICHI to build a systematic occupational therapy service system. ConclusionAn ICF-based occupational therapy concept and methodological system has been built, a comprehensive clinical occupational therapy implementation model has been established, the goal of activity and participation oriented occupational therapy interventions has been clarified, and the systematic, structured, standardized and refined level of occupational therapy has been enhanced.

In order to screen African swine fever virus (ASFV) diagnostic antigen with the best enzyme linked immunosorbent assay (ELISA) reactivity. By establishing the ELISA method, the diagnostic antigen of ASFV p30 protein expressed by baculovirus-insect cell expression system as reference, we explored the antigenic properties and diagnostic potential of ASFV p35 protein expressed by prokaryotic expression system as a diagnostic antigen. The results of Western blotting and immunofluorescence show that the molecular weight of the recombinant p35 protein and p30 protein obtained was 40 kDa and 30 kDa, respectively, and these two proteins had good immuno-reactivity with ASFV positive serum. Recombinant p30 and p35 proteins were used as diagnostic antigens to establish ELISA, and the sensitivity and repeatability of these methods were tested. The results show that although the detection sensitivity of the p30-ELISA established in this study was higher than that of the p35-ELISA, the sensitivity of p35-ELISA was 95.8%, and variations in intra- and inter-assay repeatability of the two methods were less than 10%. The coincidence rate between the p35-ELISA and the imported kit was 97.2%. Results show that p35-ELISA was sensitive and stable, and could detect specific antibodies against ASFV.
