Objective To verify the relationship between qi-yin deficiency syndrome and the etiology and diagnostic information on type 2 diabetes mellitus.Methods Data of 185 cases of qi-yin deficiency syndrome of type 2 diabetes and 351 cases of other syndromes at TCM Hospital of Hongqiao District in Tianjin and Metabolic Disease Hospital of Tianjin Medical University were randomly collected. Etiology and diagnostic information of qi-yin deficiency syndrome were screened by the likelihood radio of forward step method by using Logistic regression analysis. On this basis, the relationship between qi-yin deficiency syndrome and the etiology and diagnostic information was verified by using maximum likelihood estimation method of the structural equation model.Results The goodness of fit index of the model (GFI) was 0.909; root mean square residual (RMR) of that was 0.071; comparative fit index (CFI) of that was 0.942, which suggested that the fitting effect of the model was good. The reasonable interpretation of the relationship between qi-yin deficiency syndrome and the etiology and diagnostic information was given. Conclusion From the aspect of single syndrome factors, the relationship between qi-yin deficiency syndrome and the etiology and diagnostic information on type 2 diabetes mellitus is verified.

Objective To compare the value of dynamic ultrasound(US)and magnetic resonance imag-ing(MRI)in the diagnosis of anterior cruciate ligament(ACL)injury.Methods A total of 258 patients diagnosed with ACL knee injury between January 2019 and December 2022 at our hospital were select-ed.All patients underwent arthroscopy,followed by MRI and dynamic ultrasound(US)examinations,with the interval between the two examinations no more than 48 hours.Patients were grouped accord-ing to their injury severity(type Ⅰ oedema,type Ⅱ partial tear and type Ⅲ complete tear),injury stage(acute,≤2 weeks;subacute,2 weeks＜T≤2 months;chronic,＞2 months)and injury site(mid-,femo-ral,and tibial starting and ending tears).Then their diagnostic values of MRI and dynamic ultrasound examinations were compared using the arthroscopic results as the standard.Results A total of 258 pa-tients were included in this study.According to arthroscopic results,24 and 226 ones were diagnosed as type Ⅰ and type Ⅲ injuries,respectively,while the corresponding positive rates of MRI(100%and 99.1%)were higher than US(33.3%and 77.0%).Moreover,8 cases were diagnosed as type Ⅱ inju-ries based on the arthroscopic results.However,only 6 were correctly diagnosed by MRI with 2 misdi-agnosed as type Ⅰ injuries,while no cases were given correct diagnosis by US,with 6 and 2 misdiag-nosed as type Ⅲ and Ⅰ injuries.Out of the 234 patients arthroscopically confirmed ACL rupture,106 were in the acute phase,48 and 80 in the subacute and chronic phases.The diagnostic positive rates of MRI were 98.11%,100%,and 97.50%for patients in the acute,subacute and chronic phases,re-spectively,while the corresponding values of US were 60.38%,100%and 77.50%,respectively.More-over,the MRI diagnostic positive rate was 97.85%,100%,and 100%,while that of US was 78.49%,20.00%,and 85.71%for patients with arthroscopic femoral stop,mid-range and tibial stop tears,respectively.In patients with ACL injuries in the acute and chronic phases,as well as those with femoral stop and mid-range tears,the diagnostic positive rate of MRI was significantly higher than that of US(P＜0.05).For patients in the subacute stage,both tests had a 100%positive rate,without showing significant differences(P＞0.05).Conclusion US is superior to MRI in screening ACL injuries of different types and courses clinically,especially for those in the subacute stage.

Objective:To evaluate the degree of anxiety and depression of medical staff during the epidemic period of the COVID-19, and to provide theoretical basis for the pertinence psychological intervention timely.Methods:The investigation about the psychological status of 183 medical staffs on duty during the epidemic period was conducted using Self-Rating Anxiety Scale (SAS) and Self-Rating Depression Scale (SDS) from 18th to 20th February, 2020, who came from Tianjin and other provinces. The respondents were divided into first-line and non-first-line groups according to their jobs, and local and non-local groups according to their work places, respectively. The data was collected by "Star Questionnaires" using the mobile terminal, and the statistical analysis was carried out to compare whether there were differences in depression and anxiety among medical staff of different groups.Results:The total SAS score (48.96±9.21) and SDS score (56.69±7.57) of all medical staff were higher than those of the national norm SAS (33.80±5.90) and SDS (41.88±10.57) from 1158 individuals ( P<0.01) . Among 183 medical staff, the anxiety was found in 87 individuals and the rate of anxiety was 47.5%. The depression was found in 134 individuals and its rate was 73.2%. The anxiety combined with depression was found in 69 individuals and its rate was 37.7%. The scores of SAS and SDS of first-line group were (49.40±9.77) and (55.76±6.86) , respectively. And those of non-first-line group were (48.69±8.87) and (57.29±7.96) . They were higher than those of the national norm, and the differences were both statistically significant ( P<0.01) , but there was no difference between the first-line group and non-first-line group. The scores of SAS and SDS of local group were (48.23±9.04) and (56.76±7.05) , while those of non-local group were (50.63±9.45) and (56.54±8.71) , respectively. The differences were statistically significant ( P<0.01) , compared with the national norm respectively. But there was no difference between the local group and non-local group. No matter which classification criteria were used, there was no statistically significant difference in the severity distribution of anxiety and depression among different groups ( P>0.05) . Conclusion:The anxiety and depression exist obviously among the medical staff during the epidemic period of the COVID-19, and the psychological intervention should be taken out in time.

Objective To explore the research state and topics of lung cancer with chronic obstructive pulmonary disease (COPD) in China using the visualization methods. Methods Literature about lung cancer with COPD was searched through WanFang, CNKI, CBM, PubMed, The Cochrane Library and EMbase databases from inception to March 2018 by computer. We used BICOMS software to analyze the main information and produce co-word matrix, gCLUTO software to cluster, and NetDraw and Cytoscape software to draw the pictures. Results There were 304 studies related to lung cancer with COPD which originated from 173 journals including 23 indexed by Chinese Science Citation Database (CSCD) with 42 articles published, accounting for 13.8% of the total number of studies. There were 37 articles from 24 journals indexed by Science Citation Index (SCI) accounting for 12.2% of the total number of studies. The studies grew rapidly since 2012. The study involved 32 provinces, municipalities, and autonomous regions, among which Beijing, Sichuan, Shanghai, Guangzhou and Jiangsu provinces and cities were the main research areas. Sixty-nine high-frequency keywords were obtained with frequency 2 as the threshold, which was clustered into 5 categories by dual cluster analysis. Among them, topic 0 showed pathogenesis and radiological diagnosis of lung cancer with COPD, topic 1 was about the clinical characteristics of different pathological types of lung cancer with COPD and Chinese medicine treatment, topic 2 aimed at the impact of risk factors on surgical complications and the relationship between chemotherapy or targeted therapies and patient survival prognosis, topic 3 involved the pigenetic correlation between lung cancer and COPD and topic 4 was about clinical studies of perioperative comprehensive management of lung cancer patients with COPD. Conclusion The bibliometrics results show that there are considerable-amount achievements on lung cancer combined with COPD in China, and the researches have gradually increased since 2012. Horizontal research topics are extensive, and the focus of the study is to explore the perioperative comprehensive management and basic research of lung cancer with COPD, but the longitudinal themes need to be further studied. The results of some studies have not yet reached a consensus. There are few high-quality multi-center studies and a lack of clinical-directed achievement.
