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 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 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 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.

Objective To improve the accuracy of prescription checking and provide reference for rational drug administration. Methods Intervention mistakes exsisting in prescription checking in 2016 were retrospectively studied to analyze pharmacist' s misunderstanding during prescription checking. Results The error rate of prescription intervention was higher in department of cardiology, department of general internal medicine and department of neurology, accounting for 0.6％, 0.24％ and 0.23％, respectively.Inaccurate prescriptions for intervention, inaccurate medication and inaccurate repeat injections ranked the top 3 of erroneous prescriptions, with the proportions of 25.11％, 22.98％ and 17.45％, respectively. Conclusion Pharmacists should regularly summarize the misconceptions existed in the prescription audit, take individualized medication thoughts as guidance, strengthen the multi-disciplinary knowledge learning.

Objective To explore whether Rho kinase inhibitor protects endotoxemia mice from kidney injury,and to investigate the mechanism underlying this effect. Methods Adult male C57BL/6 mice were randomly divided into three groups (n = 8 for each group): control,lipopolysaccharide (LPS),and LPS+ Y-27632 (Rho kinase inhibitor). For induction of acute kidney injury,mice were administered 30 mg/kg LPS intraperitoneally. Y-27632 (10 mg/kg body weight) was injected intraperitoneally 18 h and 1 h before injection of LPS,and an equal volume of sterile saline was administered at the corresponding time point in each group. The mice were killed 8 h after LPS administration. Blood samples and kidney tissues were taken and preserved for subsequent analysis. Results Pretreatment with Y-27632 significantly attenuated LPS-induced kidney injury;pretreatment with Y-27632 markedly reduced renal expression of inflammatory cytokines (TNF-α and IL-1β) in endotoxemia mouse,and also significantly inhibited LPS-induced caspase-3 expression in the kidney; and Y-27632 pretreatment dramatically reduced TLR4 protein expression and NF-κBp65 phosphorylation in kidney tissues of endotoxemia mouse. Conclusion Rho kinase inhibitor may inhibit TLR4 and NF-κB signaling pathway to reduce the inflammatory response in the kidneys of endotoxemia mice and alleviate acute renal injury induced by LPS.

Objective To evaluate Chinese nurses' perception of the nursing work environment and to compare the differences among the eight economic regions in mainland China.Thus,policy-makers and nursing managers can optimize and coordinate resources based on the results of this study.Methods Chinese version of Nursing Working Environment Scale was used in the study.A total of 19,000 nurses from 31 provinces and municipalities in mainland China were investigated.Descriptive analysis,cluster analysis and nuclear density estimation were conducted.Results The average score of the nursing work environment was 4.1 points,which means nurses were somewhat satisfied with their work conditions.Specifically,nurses were most dissatisfied with the basic safeguard dimension (3.4 points),followed by sufficient manpower (3.9 points),career development (4.0) and leadership and management(4.0)dimensions.In addition,the eight economic regions could be divided into three categories(P＜0.01)according to the differences of the nursing work environment.The first category included the northeast,northern coastal and middle reaches of the Yellow River economic zone;the second category included eastern coastal economic zone;and the third category included the southern coast,the middle reaches of the Yangtze River,southwest and northwest economic zone.Conclusion The development of the nursing work environment in the vast majority of mainland China is unbalanced and the regional differences are obvious.

Objective To investigated the role of antithrombin Ⅲ (AT-Ⅲ) levels in the early diagnosis of disseminated intravascular coagulation (DIC) in patients with sepsis and the predictive effect of AT-Ⅲ on the development of DIC.Methods A retrospective study was conducted. Patients admitted to intensive care unit (ICU) of the First Affiliated Hospital of China Medical University from January to December in 2015 were enrolled. The patients were divided into sepsis group and non-sepsis group according to the diagnostic criteria of sepsis. In addition, sepsis patients were divided into 3 subgroups according to the international society on thrombosis and haemostasis (ISTH) scores on the first day: overt DIC (ISTH ≥ 5), non-overt DIC (ISTH 1-4) and none DIC group (ISTH = 0). Blood routine test, prothrombin time (PT), fibrinogen (Fib), D-dimer, fibrin degradation products (FDP), acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) scores, sequential organ failure assessment (SOFA) scores and ISTH scores were recorded on the first ICU day. AT-Ⅲ was recorded during 7 days. The differences were compared among these 3 groups. Correlations of AT-Ⅲ with various parameters were calculated by using Pearson correlation analysis in sepsis group and overt DIC group. Receiver operating characteristic (ROC) curves for diagnosis of DIC with AT-Ⅲ, AT-Ⅲ+PT were drawn to evaluate the diagnostic efficiency. The AT-Ⅲ levels of DIC patients were compared between early-onset DIC and late-onset DIC during their ICU stay. The change of AT-Ⅲ levels with time and prognosis in patients with early-onset DIC was compared between groups.Results Totally 445 patients were recruited, with 138 patients in sepsis group, and 307 in non-sepsis group. There were 20 patents diagnosed with overt DIC on the first ICU day, 115 patients non-overt DIC and 3 patients of none DIC. Twenty-five sepsis patients were diagnosed overt DIC during the ICU days. AT-Ⅲ level in sepsis patients on the first ICU day were lower than that in non-sepsis patients [(55.29±13.92)% vs. (76.54±12.31)%,P < 0.01]. Patients with overt DIC had a lower AT-Ⅲ level than non-overt DIC or none DIC patients [(43.85±13.00)% vs. (56.95±13.03)%, (68.00±16.52)%, bothP < 0.05]. It was shown by Pearson correlation analysis that AT-Ⅲ level of sepsis patients on the first ICU day was negatively correlated to ISTH score and PT (r value were -0.467, -0.654, bothP < 0.01). AT-Ⅲ level of overt DIC patient on the first ICU day was negatively correlated with PT (r = -0.675,P = 0.001). It was shown by ROC curve that area under ROC curve (AUC) of AT-Ⅲ combined with PT for diagnosis overt DIC in sepsis patients was higher than that of AT-Ⅲ or PT alone (0.843 vs. 0.763, 0.834), the sensitivity 90.0%, specificity 73.7%. The cut-off value for overt DIC diagnosis in sepsis patients of AT-Ⅲ level alone was 48.5%, sensitivity was 78.0%, specificity was 70.0%. On the first ICU day, AT-Ⅲ level was risen when ISTH score improved in patients with sepsis. There was similar change of AT-Ⅲ level between patients with early-onset DIC and late-onset DIC. AT-Ⅲ level increased with DIC improvement.Conclusion AT-Ⅲ level can be used for diagnosing sepsis-associated overt DIC independently or with a combination of PT. When ISTH score improved, AT-Ⅲ level was risen in patients with sepsis associated DIC.
