Objective:To investigate the association between dietary diversity and the risk of major adverse cardiovascular events (MACE) after percutaneous coronary intervention (PCI) in patients with coronary heart disease (CHD) .Methods:A total of 553 patients diagnosed with CHD and undergoing PCI in the Department of Cardiology at the Second Affiliated Hospital of Harbin Medical University between May and November 2023 were enrolled using a convenience sampling method. A Semi-Quantitative Food Frequency Questionnaire was used to assess patients' dietary intake after PCI, and the Dietary Diversity Score (DDS) was calculated. Patients were followed up for one year to determine the incidence of MACE.Results:History of hypertension, history of hyperlipidemia, body mass index, use of antiplatelet agents, use of diuretics, triglycerides, smoking index and DDS were identified as factors influencing the occurrence of MACE after PCI ( P<0.05) . Among these, higher dietary diversity had a protective effect against MACE. Conclusions:After PCI, patients with lower DDS experienced MACE more frequently than those with higher scores. Increased dietary diversity can effectively help prevent MACE in patients after PCI.

Objective:To explore the current dietary patterns and influencing factors of patients with coronary heart disease (CHD) in severe cold regions, aiming to provide scientific evidence for developing targeted dietary interventions.Methods:A total of 340 patients with CHD who visited the Department of Cardiology at the Second Affiliated Hospital of Harbin Medical University between September and December 2023 were selected using convenience sampling. Patients were assessed using a general information questionnaire, Semi-Quantitative Food Frequency Questionnaire, Food Choice Questionnaire, Nutritional Knowledge Questionnaire, 7-Item Generalized Anxiety Disorder Scale, and Patient Health Questionnaire-9.Results:A total of 340 questionnaires were distributed, and 333 valid questionnaires were collected, with an effective response rate of 97.94% (333/340). Two dietary patterns were identified among patients with CHD in severe cold regions: a "fruit-nut-dairy" dietary pattern and a "meat-seafood-grain" dietary pattern. Factors influencing the "fruit-nut-dairy" dietary pattern included gender, nutritional knowledge, and food choice motivations such as accessibility, sensory appeal, brand and packaging, and emotional dimensions ( P<0.05). Factors influencing the "meat-seafood-grain" dietary pattern included body mass index (BMI), living alone or not, monthly income, and food choice motivations such as convenience, health attributes, sensory appeal, and price ( P<0.05) . Conclusions:When providing dietary interventions for CHD patients, targeted control of factors such as gender, BMI, living alone or not, monthly income, nutritional knowledge, and key elements of food choice motivations may optimize patients' irrational dietary structures and reduce adverse disease outcomes.

Objective: To understand the epidemiological characteristics of pulmonary tuberculosis (PTB) in Shaanxi Province from 2016 to 2021, so as to provide the basis for improving PTB prevention and control strategies. Methods: The incidence data of PTB cases in Shaanxi Province were collected from the Tuberculosis Information Management System of the Chinese Disease Prevention and Control Information System from 2016 to 2021. The temporal, geographical, and demographic distribution characteristics of PTB were described. Results: A total of 121 280 PTB cases were reported in Shaanxi Province from 2016 to 2021, with the reported incidence rate decreasing from 56.30/105 in 2016 to 40.98/105 in 2021 (P<0.05). The etiological positivity rate increased from 16.61% in 2016 to 54.37% in 2021 (P<0.05). The average annual number of reported cases peaked in March (1 984.67 cases, accounting for 9.81%), followed by January (1 885.50 cases, accounting for 9.33%), and hit its lowest in October (1 458.50 cases, accounting for 7.22%). The incidence of PTB was relatively high in northern Shaanxi and southern Shaanxi, at 67.99/105 and 64.05/105, respectively, while it was relatively low in Guanzhong Region, at 44.83/105. The incidence rates of Ankang City (85.81/105), Fugu County (73.92/105), and Yulin City (72.20/105) ranked the top three. There were 80 111 male cases and 41 169 female cases of PTB, with a male-to-female ratio of 1.95︰1. The reported incidence rate of males (67.38/105) was significantly higher than that of females (36.61/105), and the difference was statistically significant (P<0.05). Among males, the highest average reported incidence rate was found in the 80 to <85 age group (179.46/105), while among females, the highest was in the 75 to <80 age group (104.38/105). The main occupations were farmers, accounting for 68.87% (83 526 cases). Conclusions The reported incidence rate of PTB in Shaanxi Province showed an overall downward trend from 2016 to 2021, with a high incidence in winter and spring. The epidemic in southern Shaanxi and northern Shaanxi is more severe than in Guanzhong Region of Shaanxi Province. The incidence of PTB is predominantly found among males, the elderly, and farmers.

Objective: To observe and compare the clinical effects of different electroacupuncture waveforms on primary dysmenorrhea. Methods: This was a prospective, randomized, three-group, parallel-controlled trial. Participants with primary dysmenorrhea were randomly divided into dense-sparse wave, continuous wave, and discontinuous wave groups in a 1:1:1 ratio. Two lateral Ciliao (BL 32) points were used. All three groups started treatment 3–5 days before menstruation, once a day for six sessions per course of treatment, one course of treatment per menstrual cycle, and three menstrual cycles. The primary outcome measure was the proportion with an average visual analog scale (VAS) score reduction of ≥50% from baseline for dysmenorrhea in the third menstrual cycle during treatment. The secondary outcome measures included changes in dysmenorrhea VAS scores, Cox Menstrual Symptom Scale scores and the proportion of patients taking analgesic drugs. Results: The proportion of cases where the average VAS score for dysmenorrhea decreased by ≥50% from baseline in the third menstrual cycle was not statistically significant (P > .05). Precisely 30 min after acupuncture and regarding immediate analgesia on the most severe day of dysmenorrhea, there was a statistically significant difference in the dense-sparse wave group compared with the other two groups during the third menstrual cycle (P < .05). Additionally, there was a statistically significant difference between the dense-sparse wave and discontinuous wave groups 24 h after acupuncture (P < .05). Conclusions Waveform electroacupuncture can alleviate primary dysmenorrhea and its related symptoms in patients. The three groups showed similar results in terms of short- and long-term analgesic efficacy and a reduction in the number of patients taking analgesic drugs. Regarding achieving immediate analgesia, the dense-sparse wave group was slightly better than the other two groups.

Objective:To investigate the status quo and influencing factors of the somatization of depressive emotions among college students, in order to provide a theoretical basis for the reform of mental health education and the formulation of operable mental health counseling for college students.Methods:Totally 297 college students from two institutions of higher education in Heilongjiang Province were selected by convenience sampling and investigated with the College Student Depressive Emotion Somatization Questionnaire, Attitudes Toward Seeking Professional Psychological Help Scale-Short Form (ATSPPH-SF), and the Type D Personality Scale (DS14) .Results:The total score for the College Student Depressive Emotion Somatization Questionnaire among the 297 students was (28.49±8.07), and the total score for the ATSPPH-SF was (21.98±2.73). Multiple linear regression analysis showed that the influencing factors for the somatization of depressive emotions in college students were professional psychological help-seeking attitudes and whether they had a Type D personality ( P < 0.05) . Conclusions:During university education, there should be a focus on students' personality traits and the positivity of their attitudes toward seeking professional psychological help in order to mitigate the occurrence of adverse psychological issues such as symptoms of depressive somatization.

Objective To compare and explore the differences between the eight batches of drugs in the centralized procurement list and the 2018 edition of the national essential medicine list,and to provide reference for updating and improving the national essential medicine list and the national centralized procurement list of drugs.Methods The category,generic name variety,specification,and other information of drugs included in the centralized drug procurement were collected and compared with the 2018 edition of the national essential medicine list,and the reasons for differences were analyzed.Results A proportion of 39%of centralized procurement drugs were listed in national essential medicines.Forty pharmacological classifications were not involved in the drugs of centralized procurement.Only anticoagulant and thrombolytic drugs with dual attributes accounted for a smaller variety proportion than the specification proportion.Conclusion There are some differences between the centralized procurement list and the 2018 edition of the national essential medicine list,which have some rationality,but also some problems to be solved.

Objective:To clarify the mechanism of type D personality on plaque vulnerability in patients with coronary heart disease based on the stress-mediator model.Methods:Using the convenient sampling method, a total of 386 patients with coronary heart disease who were admitted to Department of Cardiology of the Second Affiliated Hospital of Harbin Medical University from December 2020 to May 2021 were selected as the research objects. The patients were investigated using Type D Personality Scale-14 (DS-14) , Self-rating Anxiety Scale, Self-rating Depression Scale, The Stress Appraisal Measure (SAM) and Trait Coping Style Questionnaire (TCSQ) . At the same time, optical coherence tomography was used to evaluate the plaque characteristics of patients with coronary lesions. A structural equation model was used to construct a model of influencing factors of plaque vulnerability in patients with type D personality coronary heart disease.Results:Among the patients with coronary heart disease in this study, there were 138 patients with type D personality and 200 patients in the vulnerable plaque group. The D-type personality score, anxiety, depression, negative coping and cognitive evaluation scores in the vulnerable plaque group were higher than those in the non-vulnerable plaque group, and the differences were statistically significant ( P<0.01) . The active coping score of the vulnerable plaque group was lower than that of the non-vulnerable plaque group, and the difference was statistically significant ( P<0.01) . The results of structural equation modeling showed that type D personality could directly or indirectly affect plaque vulnerability through cognitive assessment (β=0.588, P<0.01) and negative coping (β=0.189, P<0.05) . Among them, cognitive assessment (β=-0.061, 0.121; P<0.01) and negative coping (β=-0.124, 0.031; P<0.01) had indirect effects on plaque vulnerability. Negative coping (β=0.215, P<0.01) , psychological responses (β=0.241, -0.150, P<0.01) and physiological responses (β=-0.321, P<0.01) had direct effects on plaque vulnerability. Conclusions:Cognitive evaluation, coping style, psychological response and physiological response of patients with type D coronary heart disease can affect plaque vulnerability through various pathways. Therefore, strengthening the clinical screening of type D personality can early identify the high-risk population of plaque vulnerability, and at the same time, individualized and systematic psychological behavior intervention should be carried out for such population, so as to move the prevention and treatment of coronary heart disease forward.
