Dysregulation of immune response is currently recognized as one of the important pathological factors in ulcerative colitis (UC). Based on the confirmation that the Sini San (SNS) can significantly improve the colon inflammation induced by dextran sulfate sodium sulfate (DSS) in mice, the present work systematically studied the xenobiotics in the colon and mesenteric lymph nodes, spleen, and thymus of UC mice after administration of SNS by high-performance liquid chromatography-ion trap time-of-flight mass spectrometry (HPLC-IT-TOF-MS). The results showed that, in addition to the colon, some components and their metabolites in SNS could be distributed in immune tissues, and it was found that the quality of relatively low-abundance and weakly responsive components such as saikosaponin a, paeoniflorin, and glycyrrhizic acid had the characteristics of efficient transmission to the colon and lymphoid organs. These components were very likely to be the source of pharmacodynamic substances of SNS. The findings of this study lay a foundation for the study of the efficacy and molecular mechanism of the components against ulcerative colitis, and also provide a scientific basis for the rational clinical application of SNS, which is expected to promote the secondary development of its preparations.

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 construct an evaluation index system for the effectiveness of cough and wheeze pharmaceutical care clinic （CWPC） among asthma patients， and to provide assessment tools and a theoretical basis for improving the control level of asthma patients and standardizing pharmaceutical care. METHODS Literature analysis and semi-structured interviews were used to establish the evaluation index system for the effectiveness of CWPC among asthma patients. Delphi method was used to conduct two rounds of expert correspondence consultation， and the index weights were determined by the analytic hierarchy process. The reliability and validity of the constructed index system were analyzed by questionnaire. RESULTS Totally 29 experts from three disciplines of medicine， pharmacy and nursing were selected from the third-grade class A hospitals in Henan province. After two rounds of expert correspondence consultation， the effectiveness evaluation index system of CWPC asthma patients （including 9 sub- dimensions， such as lung function， symptoms； 35 measurement items， such as wheezing and respiratory rate） was finally determined from three core dimensions of structure level， function level and literacy management level， and the weight value of each dimension index was determined. The results of the reliability and validity analysis confirmed the scientific rationality of the index system. CONCLUSIONS The constructed CWPC effectiveness evaluation index system for asthma patients has a high degree of recognition， reliability and validity， and can be used as a measurement tool for the effectiveness evaluation of asthma patients.

The core of diagnosing and treating diseases in traditional Chinese medicine lies in syndrome differentiation. The eight principles of syndrome differentiation serve as guidance for syndrome differentiation. As one of the eight principles of syndrome differentiation， the differentiation of deficiency and excess is the basic and critical method. Ischemic stroke is currently the leading cause harming the health of Chinese residents. Although the hypotheses about the cause of ischemic stroke have evolved from external wind to the later internal wind and to the modern theory of toxin damaging the brain collaterals， they all believe that this disease is rooted in internal deficiency and external excess. According to available studies， although stroke is characterized by complex pathogenesis and rapid progression of syndromes， the key cause evolution has a regularity， that is， from excess to deficiency. This article analyzes the historical evolution of the etiology， pathogenesis， and syndrome differentiation schemes of stroke. There are diverse schemes for the syndrome differentiation of stroke， which make it difficult to choose in clinical practice. In view of this problem， this paper puts forward a new approach of staging sequential treatment of ischemic stroke based on the differentiation of deficiency and excess according to the evolution law of the key cause of stroke. Furthermore， we conducted a randomized controlled study on 100 patients with ischemic stroke to evaluate this new approach. The results showed that the staging sequential treatment of ischemic stroke based on the differentiation of deficiency and excess demonstrated definite clinical efficacy. In addition， this article reviews the previous research results of our team and the research achievements of other teams to preliminarily explore the relationship between stroke syndromes and biomarkers， aiming to provide an objective basis for unveiling the pathogenesis of stroke. In summary， according to the key cause evolution （from excess to deficiency）， the treatment of ischemic stroke by stages based on differentiation of deficiency and excess can facilitate the rapid intervention and improve the clinical efficacy on ischemic stroke.

Background::Human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) can profoundly affect the mental health of the people living with HIV (PLWH), with higher rates of anxiety, depression, and sleep disturbances. The disparities in neuropsychological problems evaluated by physicians and self-assessed by patients are still unknown.Methods::A total of 5000 PLWH and 500 physicians from 167 hospitals were enrolled in this cross-sectional study from September 2022 to February 2023. 4-Item Patient Health Questionnaire (PHQ-4) was used for the evaluation of depressive issues and anxiety issues by PLWH. Each physician assessed 10 PLWH under their care for the presence of depressive or anxiety issues. The primary outcomes of this study are the concordance rates on the depressive issues and anxiety issues evaluation between physicians and PLWH. The Cohen’s kappa test was used to assess the agreement between physicians and PLWH.Results::The concordance rate for the evaluation of depressive issues is 73.84% (95% confidence interval [CI]: 72.60-75.04%), and it is significantly different from the expected rate of 80% ( P <0.001). Similarly, the concordance rate for the evaluation of anxiety issues is 71.74% (95% CI: 70.47-72.97%), which is significantly different from the expected rate of 80% as per the null hypothesis ( P <0.001). The overestimation rate by physicians on depressive issues is 12.20% (95% CI: 11.32-13.14%), and for anxiety issues is 12.76% (95% CI: 11.86-13.71%). The mismatch rate for depressive issues is 26.16% (95% CI: 24.96-27.40%), and for anxiety issues is 28.26% (95% CI: 27.02-29.53%). The underestimation rate by physicians on depressive issues is 13.96% (95% CI: 13.03-14.95%), and for anxiety issues is 15.50% (95% CI: 14.52-16.53%). For the treatment regiments, PLWH sustained on innovative treatment regimen (IR) related to a lower prevalence of depressive issues (odds ratio [OR] = 0.71, 95% CI: 0.59-0.87, P = 0.003) and a lower prevalence of anxiety issues (OR = 0.63, 95% CI: 0.52-0.76, P <0.001). PLWH switch from conventional treatment regimen (CR) to IR also related to a lower prevalence of depressive issues (OR = 0.79, 95% CI: 0.64-0.98) and a lower prevalence of anxiety issues (OR = 0.81, 95% CI: 0.67-0.99). Conclusion::Nearly one in three PLWH had their condition misjudged by their physicians. The findings underscore the need for improved communication and standardized assessment protocols in the care of PLWH, especially during the acute phase of HIV infection.

Objective:To explore the outcomes and problems of the Beijing Nursing Association Emergency Specialist Nurse Training Course, so as to provide reference for improving the training of emergency specialist nurses.Methods:Convenience sampling was used to select 75 trainees from the 2023 Beijing Nursing Association Emergency Specialist Nurse Training Course as survey subjects. Beijing Nursing Association Emergency Specialist Nurse Training Scoring Criteria was used to score trainees from four aspects of theoretical knowledge, skill operation, case analysis, and review defense, and to summarize and analyze the existing problems.Results:A total of 75 questionnaires were distributed, and 75 valid questionnaires were collected, with a valid response rate of 100.0%. The theoretical knowledge score was (68.4±10.7), with a minimum of 38.0 and a maximum of 91.0, and the pass rate (number of passing trainees divided by the total number of trainees) was 81.3%. The score for the review defense was (78.8±5.7), with a minimum of 65.0 and a maximum of 94.0, and a pass rate of 100.0%. The skill operation score was (93.5±3.7), with a minimum of 85.0 and a maximum of 99.0, and a pass rate of 100.0%. The score for the case analysis was (90.2±5.6), with a minimum score of 80.0 and a maximum score of 100.0, and a pass rate of 100.0%. The main reasons for losing points in the theoretical knowledge were mechanical ventilation and cardiopulmonary resuscitation. The main reasons for losing points in the review defense were topic selection and paper writing. The main reasons for losing points in skill operation were preparation before operation and key points after operation. The main reasons for losing points in the case analysis were the consultation ideas and treatment measures.Conclusions:The trainees of the emergency specialist nurse training course currently have a relatively good overall professional practical skills, but there are significant differences in theoretical knowledge, weak scientific research capabilities, and room for improvement in triage decision-making. It is suggested to give full play to the advantages of teachers and set up a variety of Internet courses for trainees to learn on their own to meet the personalized needs of trainees and improve teaching homogeneity.

Objective:To explore the application of beside wheelchair seating training in patients with acute respiratory distress syndrome (ARDS) and mechanical ventilation, so as to provide the reference for the nursing of acquired myasthenia in EICU.Methods:A total of 66 ARDS patients with mechanical ventilation treated in Beijing Hospital from July 2017 to July 2019 were assigned to the experimental group and the control group according to the admission time, 33 cases in each group. Patients in the control group received routine nursing, while the experimental group implemented beside wheelchair seating training. The differences in muscle strength, self care ability, duration of mechanical ventilation, length of EICU stay as well as complications between the two groups were compared.Results:The incidence of EICU acquired myasthenia in the experimental group was 18.2% (6 cases), which was significantly lower than that in the control group 42.4% (14 cases), the difference was statistically significant ( χ2=4.59, P<0.05). Out of EICU, the Medical Research Council (MRC) scores and Modified Barthel Index (MBI) scores were (48.27 ± 5.11), (59.67 ± 7.33) points in the experimental group, which were significantly higher than those in the control group (44.88 ± 6.75), (54.06 ± 8.53) points, the differences were statistically significant ( t=2.30, 2.86, both P<0.05). The length of EICU stay and duration of mechanical ventilation were (8.24 ± 1.48) d, (7.15 ± 1.48) d, in the experimental group, which were significantly lower than those in the control group (9.85 ± 2.99) d, (8.24 ± 1.77) d, the differences were statistically significant ( t=2.77, 2.72, both P<0.05). The oxygenation index after 30 minutes of weaning was (296.64 ± 15.45) mmHg (1 mmHg=0.133 kPa), which was significantly higher than that in the control group (288.36 ± 16.75) mmHg, the difference was statistically significant ( t value was 2.09, P<0.05). Conclusions:The beside wheelchair seating training can effectively decrease the incidence of EICU acquired myasthenia as well as shorten the duration of mechanical ventilation and length stay in EICU of patients with ARDS. It is safe and effective, and has good clinical application value.

Tertiary lymphoid structure (TLS) is the ectopic lymphoid tissue around the chronic inflammatory site of tumor, infection diseases, autoimmunity diseases, organ transplantation and so on. TLS is regarded as the vital niche of antitumor immune response in tumor microenvironment for abundant immune cells, and is correlated with better clinical outcomes and immunotherapy response in most solid tumors. As a typical inflammation-driven cancer, hepatocellular carcinoma (HCC) is controversial with the influence of TLS on patients prognosis. In this paper, the composition, formation mechanism, recognition and clinical value of TLS in HCC were briefly reviewed.
