Infectious diseases occur and evolve through a dynamic contest between pathogenic qi and the body's healthy qi， with marked stage-dependent progression. This paper constructs a whole-course system of syndrome differentiation and treatment based on the theories of "struggle between pathogenic qi and healthy qi" and "relapse due to overexertion after recovery". The former reveals the intrinsic link between the waxing and waning of pathogenic and healthy qi and the evolution of syndromes， guiding stratified interventions during acute stage by discerning the location and nature of pathogenic factors and determining appropriate strategies for eliminating pathogens and supporting healthy qi according to the dynamics of deficiency and excess syndromes. The latter focuses on the recovery stage after infection and disease relapse， emphasizing harmonizing yin， yang， qi and blood to restore functions of zang-fu （脏腑） organs， and combining unblocking， tonifying， and turbidity-dispelling methods to eliminate both new and lingering pathogens. Throughout the whole-course treatment， attention should be paid to dynamic pathogenesis and stage-to-stage coherence， with emphasis on formula-syndrome correspondence， and integration of modern diagnostic and therapeutic measures， to construct individualized strategies bridging disease stages and integrating prevention with treatment， thereby systematically leveraging the integrative strengths of traditional Chinese medicine in the prevention and treatment of infectious diseases.

Objective:To investigate the effects of intravenous lidocaine infusion (IVLI) on the quality of intraoperative neurophysiologic monitoring (IONM) in patients with thyroid tumor.Methods:A prospective randomized controlled study was conducted. A total of 60 patients with thyroid tumor undergoing thyroidectomy in the First Clinical Medical College of Shanxi Medical University between September 2022 and May 2023 were selected. According to the random number table method, all patients were divided into the lidocaine group and the control group, 30 cases in each group. The patients in the lidocaine group were continually given IVLI during the operation and the patients in the control group were continually given the equal 0.9% NaCl solution infusion during the operation. All patients in the 2 groups were induced by the same way of total intravenous anesthesia, and no muscle relaxants were added during anesthesia except the induction dose, and enhanced nerve monitoring tracheal catheter was inserted in the 2 groups. According to the standardized procedure of IONM, the electrode impedance values were measured at the time of eliciting the V1 and V2 signals from the vagus nerve, respectively, and the difference value was defined as the drop in the aggregate impedance level (DAIL). DAIL, perioperative hemodynamic parameters and postoperative recovery quality were compared between the 2 groups.Results:There were no statistically significant differences in the baseline data, operation time, intraoperative dosage of propofol and remifentanil between the 2 groups (all P > 0.05). Compared with the control group, the lidocaine group had a higher proportion of patients with DAIL<50% [80.0% (24/30) vs. 40.0% (12/30), χ2 = 10.00, P = 0.002], a lower hemodynamic fluctuation during extubation [mean arterial pressure: (95±6) mmHg (1 mmHg = 0.133 kPa) vs. (104±7) mmHg, t = 31.00, P < 0.001; heart rate: (73±5) times/min vs. (92±6) times/min, t = 172.58, P < 0.001], a lower visual analog score 24 h after surgery [(2.0±0.7) scores vs. (3.7±0.8) scores, t = -8.86, P < 0.001], a higher score of quality of recovery-15 scale [(127±11) points vs. (118±13) points, t = 2.92, P = 0.005]. Conclusions:IVIL can improve the quality of IONM in patients with thyroid tumor during surgery, reduce perioperative hemodynamic fluctuation and improve postoperative recovery quality of patients.

Objective: Based on the theoretical framework of Risk Perception-Efficacy Appraisal-Behavioral Response, the study aims to explore the group heterogeneity in high temperature health risk perception and behavioral responses among college students in Chongqing, so as to provide a scientific basis for implementing differentiated health interventions. Methods: A multi stage cluster sampling method was used to select 856 students from five universities in Chongqing. Data were collected using a validated questionnaire. One way analysis of variance and independent samples t-test were used to analyze individual differences, Pearson correlation analysis was employed to examine relationships between variables, multiple linear regression was used to identify influencing factors, a structural equation model was constructed to validate the theoretical pathways, and the Bootstrap method was applied to test mediating effects. Results: In the risk perception dimension, the severity score of high temperature health hazards among college students (3.28±0.89) was higher than that of susceptibility score (2.94±0.93). Efficacy appraisal showed that the response efficacy score was the highest (3.91±0.81). In behavioral responses, adaptive behaviors were most prominent (5.43±2.75), while emergency preparedness behaviors were the lowest (2.71±1.33). The structural equation model validated the pathway of "threat appraisal → efficacy appraisal → behavioral response" ( χ 2/df=2.49, RMSEA =0.05). Self efficacy played a fully mediating role between threat appraisal and behavioral response, with a mediation effect value of 0.10 (95% CI =0.02-0.19). K means cluster analysis categorized the subjects into three groups, with the core barriers to behavior being economic constraints (22.3%), lack of motivation (34.8%), and insufficient cognition (34.1%), respectively. Conclusions Decision making regarding high temperature health behaviors among college students follows psychological pathway of "cognition-appraisal-action" with self efficacy serving as a key mediating variable driving behavioral change. Targeted interventions should be implemented for groups with different characteristics.

ObjectiveTo investigate the effects of Tongxinluo capsules on traditional Chinese medicine （TCM） syndrome elements and major adverse cardiovascular events （MACEs） in patients with chronic coronary syndrome of Qi deficiency and blood stasis type. MethodsA multicenter and prospective cohort study was conducted. The intervention of Tongxinluo Capsules was used as the exposure factor， and the patients were divided into an exposure group （integrated traditional Chinese and western medicine treatment group） and a non-exposure group （western medicine treatment group）. The patients were followed up for one year. The TCM syndrome element scores were assessed by using a syndrome element diagnosis scale on the day of enrollment and in the third， sixth， and twelfth months， and the incidence of MACE within one year was recorded. ResultsA total of 186 patients were included， with 128 patients in the exposure group and 58 patients in the non-exposure group. There was no significant difference in baseline data between the two groups. Compared with those in the pretreatment period for each group， the Qi deficiency and blood stasis syndrome scores in the treatment and follow-up period were significantly improved （P<0.05）. Compared with the non-exposure group， the exposure group exhibited significantly decreased Qi deficiency syndrome scores in the treatment and follow-up period （P<0.01） and significantly reduced blood stasis syndrome scores in the sixth month （P<0.05）. In the remaining follow-up period， there was no statistically significant difference between the two groups. Compared with that of the non-exposure group， during the treatment period （the third month）， the difference in Qi deficiency and blood stasis syndrome scores of the exposure group was statistically significant （P<0.05， P<0.01）. At the end of the follow-up period， patients in the non-exposure group had a MACE probability of 6.90% （4/58）， higher than 3.13% in the exposure group （4/58）. Compared with patients with angina pectoris who used conventional medicine， patients administered with Tongxinluo Capsules had a relative risk（RR） of 0.45 ［95%confidence interval（95%CI） 0.12-1.75， P=0.26］. There was no significant difference in the incidence of MACE within one year between the two groups. ConclusionTongxinluo capsules can improve the degree of Qi deficiency in patients with chronic coronary syndrome in the short term， and the improvement effect of blood stasis syndrome appears in the medium and long term. They can better improve the Qi deficiency syndrome in the long term. Within one year， the incidence of MACE in the exposure group was lower than that in the non-exposure group.

OBJECTIVE: To investigate the genetic etiology of six adult patients with Dilated cardiomyopathy (DCM), and analyze the structure of the identified variants, for providing reference for the diagnosis of DCM. METHODS: Six adult patients with DCM (patients 1-6) admitted to the Department of Cardiology of Zhumadian Central Hospital from January 2023 to December 2023 were recruited. Clinical data of the patients were retrospectively collected. And 5 mL of peripheral blood was collected from each patient. Pathogenic variants of the patients were detected by whole exome sequencing (WES), and candidate variants were verified by Sanger sequencing. The possible functional significance of the identified missense variants was evaluated using software including SIFT, PolyPhen-2 and Mutation Taster. Specific regions of the MYBPC protein encoded by the MYBPC3 gene from different species were aligned using Mutation Taster. The wild-type and mutant MYBPC proteins were constructed using homologous modeling software MODELLER v10.4 and three-dimensional structures were visualized using PyMOL software. The molecular interaction between MYBPC-C5 domain and myosin with or without the mutation was further analyzed using ZDOCK module in Discovery Studio 2019 software. Pathogenicity ratings for the detected variant sites were performed in accordance with the Standards and Guidelines for the Interpretation of Sequence variants by the American College of Medical Genetics and Genomics (ACMG) (hereafter referred to as the ACMG Guidelines). This study was reviewed and approved by the Ethics Committee of Zhumadian Central Hospital (Approval No. 2022092007). RESULTS: The six DCM patients had typical symptoms of heart failure, and echocardiography showed whole-heart dilation and decreased ventricular wall motion, left ventricular end-diastolic dimension (LVEDD) was 59-74 mm, left ventricular ejection fraction (LVEF) was 35%-43%, and left ventricular fractional shortening (LVFS) was 17%-28%. Variations of the DCM related genes, including a c.98473A>T (p.Lys32825*) variation of the TTN gene and a c.1976T>C (p.Ile659Thr) variation of the MYBPC3 gene, were identified in two patients. Multiple software predicted that both mutations were deleterious. MYBPC3-Ile659Thr mutation affected the highly conserved residue within the C5 domain of MYBPC. Three-dimensional structural analysis of homologous modeling revealed the alterations in amino acid properties and interactions with surrounding amino acids caused by the MYBPC3-Ile659Thr mutation. Further molecular docking analysis showed that the Ile659Thr mutation altered both the hydrogen bond and salt-bridge interactions between the MYBPC-C5 domain and the ligand myosin. CONCLUSION Two mutations associated with DCM were identified in this study. The abnormal conformation of the mutant protein further affected its interaction with the ligand myosin, resulting in the phenotype of DCM.
