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 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 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 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::Microchannels are associated with the progression of atherosclerotic vulnerable plaques. However, in patients with culprit optical coherence tomography (OCT)-defined plaque erosion, the knowledge of microchannels and culprit lesion vulnerability is limited. The aim of this study was to investigate culprit lesion characteristics in patients with ST-segment elevated myocardial infarction (STEMI) caused by plaque erosion with and without microchannels using OCT.Methods::In all, 348 STEMI patients with plaque erosion who underwent OCT of the culprit lesion at the 2 nd Affiliated Hospital of Harbin Medical University (Harbin, China) from August 2014 to December 2017 were included and divided into the microchannel group ( n= 116, 33.3%) and no-microchannel group ( n = 232, 66.7%). The clinical characteristics and OCT-derived plaque features were compared between both groups. Results::Among the 348 STEMI patients with plaque erosion, culprit lesions with microchannels had higher incidence of lipid plaque (59.5% vs. 45.3%, P= 0.012); calcification (41.4% vs. 24.6%, P= 0.002); spotty calcification (30.2% vs. 18.1%, P= 0.014); macrophages accumulation (72.4% vs. 45.7%, P < 0.001); and cholesterol crystals (32.8% vs. 14.2%, P < 0.001) than those without microchannels. In addition, minimal lumen area was smaller ((1.9 ± 0.9) mm 2vs. (2.8 ± 2.3) mm 2, P < 0.001) and lumen area stenosis was greater ((71.3% ± 13.4%) vs. (65.3% ± 19.3%), P= 0.001) in the microchannel group than in the no-microchannel group. Conclusion::In patients with STEMI caused by plaque erosion, one-third manifested typical microchannel characteristics, and those with microchannels were associated with more severe luminal stenosis and more vulnerable plaque features than those without microchannels.
