Objective:To explore the mediating role of disease progression′s fear and positive affect in the relationship between disease perception and demoralization in patients with chronic heart failure. It provided a theoretical basis for targeted interventions for healthcare workers.Methods:From October 2022 to March 2023, 320 patients with chronic heart failure in the First Affiliated Hospital of Zhengzhou University were selected as the research objects by convenience sampling. The General Information Questionnaire, Demoralization Scale Redacted Mandarin Version, Brief Illness Perception Questionnaire, Fear of Progression Questionnaire-Short Form, Positive and Negative Affect Schedule (Positive Affect Schedule) were used to conduct the questionnaire survey exploring the mediating effects of fear of disease progression and positive emotions between disease perception and disorientation by construction structural equation model.Results:There were 268 valid questionnaires. Of the 268 patients, 168 were male and 100 were female, 3.36% (9/268) were ≤40 years old, 55.22% (148/268) were 41-65 years old, and 41.42% (111/268) were >65 years old. Correlation analysis showed that disease perception was positively correlated with disease progression ′s fear, and every dimension of demoralization ( r values were 0.300-0.586, all P<0.01), and negatively correlated with positive affect ( r=-0.374, P<0.01); disease progression′s fear was negatively correlated with positive affect ( r=-0.318, P<0.01), and positively correlated with every dimension of demoralization ( r values were 0.339-0.464, all P<0.01); positive affect was negatively correlated with every dimension of demoralization ( r values were -0.430--0.334, all P<0.01). Structural equation model analysis showed that the direct effect of disease perception on demoralization was significant ( β=0.407, P<0.01), and both mediating effects of disease progression ′s fear and positive affect between disease perception and demoralization in patients with chronic heart failure were significant ( β=0.074, 0.079, both P<0.01). The chain mediating effect of disease progression ′s fear and positive effect was also significant ( β=0.019, P<0.01). Conclusions:Disease perception could directly predict the demoralization of patients with chronic heart failure and indirectly predict the demoralization of patients with chronic heart failure through the mediating effect of disease progression ′s fear, positive affect, and the chain mediating effect of disease progression ′s fear and positive affect.

Objective It aims to construct an evaluation index system for the development level of intelligent health insurance,which can serve as a reference for health insurance management departments in assessing the develop-ment level of intelligent health insurance and the implementation of health insurance informatization.Methods Key events in intelligent health insurance were identified based on event system theory and text analysis.The evaluation index system was determined through a combination of expert interviews and Delphi expert consultations.The entro-py method was used to calculate the weights of each index,followed by the assessment of the current and ideal de-velopment levels.Results A total of 16 experts were consulted.After two rounds of Delphi expert consultation,two first-level indicators and 18 second-level indicators were finally included in the system.The current development level of intelligent health insurance in China is at the intelligent development stage(2.524 points),while the ideal de-velopment level is at the intelligent improvement stage(4.073 points).The positivity coefficient of both rounds of Del-phi expert consultation was 100%,with an authority coefficient of 0.842,and the degree of expert coordination im-proved with each round.Conclusion The constructed evaluation index system exhibits high scientificity,stability,and generalizability.It can provide an effective evaluation tool for the development of intelligent health insurance in various pooled areas.

Objective:To analyze the risk factors of internalizing problems in adolescents aged 12 to 18 years,and provide supporting evidence for the scientific prevention and effective control of internalizing problems in adolescents.Methods:By systematically searching the Chinese and English databases such as CNKI,VIP,Wan-fang,PubMed,Web of Science,Psychology and Behavioral Sciences Collection,PsycInfo,PsycArticles and ERIC,literature on risk factors of internalizing problems among adolescents in the past 22 years was collected,and non-clinical literature using CBCL or YSR or TRF scales to measure related internalizing problems were included.Meta analysis was performed using CMA3.0,with r as the effect size indicator and random effects model combined with the effect size of risk factors.Results:Finally,77 and 18 risk factors literatures were included,including 7 risk fac-tors of individuals,7 risk factors of family,and 4 risk factors of school/community.The average correlation between family risk factors and internalizing problems of adolescents was the highest.Among family risk factors,parent-child attachment had the highest correlation.Conclusion:Individual risk factors,family risk factors and school/com-munity risk factors are significantly positively correlated with adolescent internalizing problems,and family risk fac-tors(especially parent-child attachment quality)have the highest correlation with adolescent internalizing problems.

Objective To explore the clinical efficacy and safety of probiotic-assisted chemotherapy in patients advanced colorectal cancer(CRC).Methods Patients with advanced CRC admitted to the First Affiliated Hospital of Hunan Normal University from March 2022 to March 2023 were enrolled.CRC patients were randomly divided into the test group(Bifidobacterium triple viable capsule,capecitabine+oxaliplatin)and the control group(capecitabine+oxaliplatin)by random number table method.The short-term efficacy(objective response rate and disease control rate),incidence of gastrointestinal adverse reactions,Karnofsky performance status(KPS)score,and serum tumor markers CA72-4,CA19-9 and CEA levels were compared between the two groups.Results A total of 120 patients with CRC were included,including 60 patients in the test group and 60 in the control group.Compared with the control group,the objective remission rate and disease control rate in the testl group were significantly higher(P<0.05).There was no significant difference in the incidence of nausea and acid reflux between the two groups(P>0.05),and the incidences of abdominal pain,bloating,constipation and diarrhea in the test group were significantly lower than those in the control group(P<0.05).There was no significant difference in KPS score,serum CA72-4,serum CA19-9 and serum CEA levels between the two groups before treatment(P>0.05),and after 4 weeks of treatment,the KPS score of the test group was significantly higher than that of the control group(P<0.05),and the serum levels of CA72-4,serum CA19-9 and serum CEA were lower than those of the control group(P<0.05).Conclusion Probiotics-assisted chemotherapy improve the near-term efficacy,reduce gastrointestinal adverse effects,and improve the quality of life in patients with advanced CRC.

Temporomandibular joint (TMJ) diseases are common clinical conditions. The number of patients with TMJ diseases is large, and the etiology, epidemiology, disease spectrum, and treatment of the disease remain controversial and unknown. To understand and master the current situation of the occurrence, development and prevention of TMJ diseases, as well as to identify the patterns in etiology, incidence, drug sensitivity, and prognosis is crucial for alleviating patients′suffering.This will facilitate in-depth medical research, effective disease prevention measures, and the formulation of corresponding health policies. Cohort construction and research has an irreplaceable role in precise disease prevention and significant improvement in diagnosis and treatment levels. Large-scale cohort studies are needed to explore the relationship between potential risk factors and outcomes of TMJ diseases, and to observe disease prognoses through long-term follw-ups. The consensus aims to establish a standard conceptual frame work for a cohort study on patients with TMJ disease while providing ideas for cohort data standards to this condition. TMJ disease cohort data consists of both common data standards applicable to all specific disease cohorts as well as disease-specific data standards. Common data were available for each specific disease cohort. By integrating different cohort research resources, standard problems or study variables can be unified. Long-term follow-up can be performed using consistent definitions and criteria across different projects for better core data collection. It is hoped that this consensus will be facilitate the development cohort studies of TMJ diseases.

Objective To analyze and compare the clinical effects of femoral neck dynamic cross screw system(FNS)and cannulated screws(CS)in the treatment of vertically unstable femoral neck fractures.Methods The clinical data and short-term follow-up results of 40 patients with vertically unstable femoral neck fractures admitted from July 2020 to August 2021 were retrospectively analyzed.According to different internal fixation methods,40 patients were divided into two groups,20 cases in FNS group included 11 males and 9 females with a median of 58.5(50.3,62.5)years old,and 20 in CS group included 9 males and 11 females with a median of 52.0(40.5,58.0)years old.The operation time,knife edge length,blood loss and treatment cost of two gruops were observed and compared.The postoperative fracture healing and internal fixation were evaluated with X-ray imaging data,and the femoral neck shortening of the affected side was measured.The incidence of thigh irritation,the time of partial weight bearing and full weight bearing,early necrosis of femoral head,reoperation revision and Harris scores were compared between two groups.Results FNS group was followed up for 18.0(15.0,19.0)months,CS group for 17.0(15.0,18.8)months.There was no significant difference in operation time,incision length and blood loss between two groups(P＞0.05).The cost of diagnosis and treatment in FNS group was higher than that in CS group(P＜0.001).In FNS group,there was no irritation sign of the affected side thigh,while in CS group,there were 6 cases with discomfort or irritation sign of the lateral thigh(P＜0.05).The average time of partial weight bearing activity in CS group was later than that in FNS group(P＜0.05);However,there was no significant difference in the activity time of complete weight bearing between two groups(P=0.011＞0.05).At the last follow-up,the shortened length of the affected femoral neck in CS group was greater than that in FNS group(P＜0.05).There was no early necrosis of femoral head and reoperation in both groups.There was no significant difference in Harris score be-tween two groups 12 months after operation(P＞0.05).Conclusion FNS treatment of vertically unstable femoral neck fractures can significantly reduce the incidence of lateral thigh irritation sign,and effectively reduce the postoperative shortening rate of vertically unstable femoral neck fractures,which can provide a relatively stable anti rotation force and anti cutting force,so that patients can go to the ground relatively early,which is conducive to the recovery of the affected hip joint function after surgery.It is a new option for the surgical treatment of vertically unstable femoral neck fractures.However,due to the high cost of treat-ment,In clinical practice,appropriate surgical treatment is selected according to the actual situation.

Protein as the allergens could lead to allergy. In addition, a widespread class of allergens were known as glycans of N-glycoprotein. N-glycoprotein contained oligosaccharide linked by covalent bonds with protein. Recently,studies implicated that allergy was associated with glycans of heterologous N-glycoprotein found in food, inhalants, insect toxins, etc. The N-glycan structure of N-glycoprotein allergen has exerted an influence on the binding between allergens and IgE, while the recognition and presentation of allergens by antigen-presenting cells (APCs) were also affected. Some researches showed thatN-glycan structure of allergen was remodeled by N-glycosidase, such as cFase I, gpcXylase, as binding of allergen and IgE partly decreased. Thus, allergic problems caused by N-glycoproteins could potentially be solved by modifying or altering the structure ofN-glycoprotein allergens, addressing the root of the issue. Mechanism of N-glycans associated allergy could also be elaborated through glycosylation enzymes, alterations of host glycosylation. This article hopes to provide a separate insight for glycoimmunology perspective, and an alternative strategy for clinical prevention or therapy of allergic diseases.
