ABSTRACT
OBJECTIVE To understand the current status of research on traditional Chinese medicine（TCM） human resources， and to provide a reference for expanding research ideas on TCM human resources and promoting the construction of TCM talents. METHODS From January 1， 2000 to December 31， 2022， literature related to TCM human resources was collected from the three major databases of CNKI， Wanfang and VIP. Using CiteSpace 5.8 R3 software， visualization analysis was performed for the literature in terms of publication time， journal sources， authors， institutions and areas， funding， research content， keywords， etc. RESULTS A total of 324 literature related to TCM human resources in China were included， and the number of literature issued showed an upward trend， with an annual average of 14.09 literature； 161 kinds of journals were involved， core journals accounted for 18.21% of the total publication volume； a total of 23 authors had published 2 or more literature， with a total of 55 literature published （16.98%）； a total of 416 institutions were involved， mainly schools （66.83%）； 60.49% of the literature were supported by the fund. The majorities of 324 literature were survey studies （170 literature）， and most of them used self-designed questionnaires （55 literature）； the high-frequency keywords included talent training， human resources， TCM， etc. The keywords were clustered into 7 categories， such as “human resources“”talent training“”TCM industry“”TCM services“”talent training models” “fairness” and “TCM talents”. The main problems described in the literature included insufficient talent， lack of reasonable distribution of regional structure， lack of reasonable plans for talent training， and insufficient professional knowledge and abilities. Continuously cultivating high-level talents and improving employment conditions in areas with severe human resource loss were the corresponding countermeasures proposed in the literature. CONCLUSIONS The research on TCM human resources starts late but has developed rapidly overall， and the quality of research needs to be improved； the structure of research team is single and unevenly distributed geographically； there is a structural imbalance in the allocation of human resources， as well as problems such as a shortage of professional talents， low levels of education and training and incomplete development systems.
ABSTRACT
【Objective】 To compare the histological characteristics of porcine pancreatic elastase （PPE） induced abdominal aortic aneurysms （AAA） and angiotensin Ⅱ （AngⅡ） induced AAA in mice. 【Methods】 In the PPE group， the mouse abdominal aorta segment from the infrarenal abdominal aorta to the iliac artery was isolated and its branch arteries were ligated to avoid leakage during PPE perfusion. We perfused the isolated aorta segment with a PPE solution at a concentration of 1.5 U/mL for 5 min and then closed the abdominal cavity. The diameter of the abdominal aorta was measured before and 14 days after the surgery， and the perfusion segment of the arteries was collected at day 14 after the surgery. The histological characteristics of the aneurysm were analyzed and graded by histological and immunohistochemical methods. In the AngⅡ group， ten apolipoprotein E knockout mice were prepared， and AngⅡ [1 000 ng/(kg·min)] was infused with osmotic pumps for 28 days. The aorta was separated and the aneurysm aorta segment was analyzed. The wild type mice were used as normal health controls. 【Results】 In the PPE group， the diameter of the PPE perfused aorta segments increased and was significantly larger than the basal diameter ［（0.52±0.02） mm vs. （1.23±0.11） mm］ at day 14 after surgery. All the ten mice developed AAA after PPE application. The histological results showed typical pathological features of AAA in PPE perfused mice， such as elastic fiber breakage， smooth muscle exhaustion， and increased inflammation. Six of the ten mice developed aneurysms after AngⅡ infusion （6/10）. The aneurysms/dilatations were mostly in the suprarenal abdominal aorta， but also in the thoracic aorta and aortic arch. The histology analysis showed that the formation of arterial dissection was common after AngⅡ infusion， and the typical vascular “false lumen” was found. The breakage of elastic fibers， the exhaustion of smooth muscle damage， and the inflammatory response were not as typical as the PPE model in AngⅡ perfused animals. 【Conclusion】 The histological characteristics of PPE induced AAA are very typical and well present the inflammatory process in the development of aneurysm. The AngⅡ model is suitable for the study of aneurysms combined with aortic dissection. Both models have their own advantages and can complement each other.
ABSTRACT
Objective: To explore the effect of transthoracic color Doppler echocardiography on evaluating myocardial impact injury caused by eccentric aortic regurgitation (AR). Methods: Transthoracic color Doppler echocardiographic imaging data were collected in 26 cases with local deformation of some part of the ventricular septum or left ventricular free wall rammed by moderate and above eccentric AR, and the morphological characteristics of ventricular wall impact injury were analyzed. Results: Myocardial impact injury caused by eccentric AR located at the basal-mid segment of ventricular septum or left ventricular wall (26/26, 100%). Both inferoseptal and inferior wall were impacted in 4 cases (4/26, 15.38%), only inferior wall were impacted in 5 cases (5/26,19.23%), both inferior and inferolateral wall in 13 cases (13/26, 50.00%), inferolateral wall in 2 cases (2/26, 7.69%), while inferoseptal, inferior and inferolateral wall all were impacted in 2 cases (2/26, 7.69%).No anterolateral, anterior nor anteroseptal wall was impacted. Local dilatation was observed at the impacted wall in all cases (26/26, 100%). Severe hypokinesia was detected in 6 cases(6/26, 23.08%), mild hypokinesia in 10 cases(10/26, 38.46%),while normal motion was observed in the rest 10 cases(10/26, 38.46%). In addition to local wall dilatation and hypokinesia, myocardial fibrosis could be observed from LGE images in one case. Local perfusion and metabolism decreased on radionuclide perfusion images in severe cases, but not in mild cases. Conclusion: Moderate and above eccentric AR can cause damage to some part of the wall impacted directly by the eccentric aortic regurgitation, and the location and extent of damage can be evaluated using color Doppler echocardiography.
ABSTRACT
Objective To analyze the types and risk factors of community-acquired infections (CAI)in diabetic patients by system analysis method of evidence-based medicine.Methods China National Knowledge Infrastructure (CNKI),Wanfang database,VIP database were searched by computer,domestic published researches on CAI and related risk factors in dia-betic patients were aggregated,Meta-analysis was conducted by stata 1 1 .0 software.Results A total of 1 2 literatures were included in the study .The average rate of CAI in diabetic patients was 39.55% (22.12%-55.86%).The major infec-tions were respiratory system infection(40.74%),urinary tract infection(27.35%),tuberculosis(10.80%),skin and soft tissue infection(9.19%),and hepatobiliary system infection (5.57%).Stratified analysis on risk factors revealed that OR and OR95%CI of chronic complication,age,disease course,glycemic control,gender,type of diabetes,subtype of ketoac-idosis was 1.63(1.45,1.82),1.30(1.19,1.42),1.47(1.35,1.61),0.68(0.61,0.76),0.69(0.64,0.75),1.37 (1.13,1.66 )and 0.87(0.62,1.23),respectively.There was no publication bias and combined results were stable. Conclusion The main CAI in diabetic patients are respiratory system infection,urinary tract infection,tuberculo-sis,skin and soft tissue infection,and so on ;several factors,such as female,older age,long-term disease course, poor glycemic control,and complication,can contribute to the increase of CAI in diabetic patients.
ABSTRACT
A survey on smoking status and risk factors was conducted among 3373 residents in two districts of Shen yang city during November 2008 and September 2009 ; the pulmonary function tests were also performed for all subjects.A logistical regression model was used to evaluate the risk factors of smoking,and the knowledge about diseases caused by smoking was evaluated by chi-square test.The overall smoking rate was 50.7％ ( 1710/3373 ) ; 86.8％ (1458/1680) for males a(un)14.9％ (252/1693)for females.The risk factors of smoking ( P ＜ 0.05 ) in order of OR value were as follows:drinking,work environment and underlying diseases ; the protective factors were:female,educational level,overweight ( BMI ≥ 24) and old age.The survey on knowledge of smoking-related disease was conducted in 2478 residents including 815 smokers and 1663 non-smokers. The awareness levels about whether smoking can cause COPD,asthma,birth defects,malignant tumor,abortion,growth retardation,fetal death and myocardial infarction were significantly different between smokers and non-smokers.
