Objective To compare intravascular ultrasound (IVUS) and coronary angiography in measuring the lumen diameter and coronary arteries stenosis rate, to investigate the impact of IVUS in the choice of surgical indications, surgical procedure guidance and effects of operation.Methods The patients who underwent percutaneous coronary intervention(PCI) therapy from may 2013 to may 2014 were divided into IVUS-guided intervention therapy group (n=89) and coronary angiographyguided group (n=90).Their baseline parameters, lesion features, MACE and restenosis during follow-up were analyzed.Results Baseline clinical and angiographic characterisitcs were well matched and show no significant differences between the two groups.Compared to angiography-guided group, the minimum lumen diameter (MLD) of IVUS-guided group were higher, diameter stenosis (DS) and lesion length (LL) were lower in IVUS-guided intervention therapy group.The detection rate of calcified and eccentric lesion were significantly higher in IVUS-guided group.There were 204 (93.6 ％) and 195 (87.8％) high-pressure balloons used in post-inflation in two groups, respectively.The MLD and plaque burden of IVUS-guided group were obviously improved after stent implantation.Conclusions IVUS-guided intervention therapy in PCI is safe and effective, may be helpful for the judgment of lesion, evaluating stent implantation and guiding high-pressure balloon post-inflation.IVUS-guided intervention could get the bigger immediate lumen diameter and lower plaque burden than coronary angiography without serious short-term or long-term complications.

Objective: To investigate the mental health literacy levels among residents in Ningbo City, so as to provide the evidence for implementing the mental health service policy and targeted mental health education. Methods: Permanent residents at ages of 12 years and older were recruited in Ningbo City using the multi-stage stratified random sampling method from August to December, 2020. Subjects' mental health literacy levels were evaluated using the national mental health literacy survey of China, and the gender-, age-, region- and educational level-specific levels of mental health literacy were investigated. Results: A total of 6 654 questionnaires were allocated, and 6 392 valid questionnaires were recovered, with an effective recovery rate of 96.06%. The respondents included 2 967 men ( 46.42% ) and 3 425 women ( 53.58% ). The respondents were predominantly at ages of 18 to 44 years ( 2 705 residents, 40.19%) , lived in urban areas ( 3 823 residents, 59.81% ), and had an educational level of junior high school and below ( 3 195 residents, 49.98% ). The level of mental health literacy was 19.06%, and the score of mental health knowledge was ( 64.06±18.39 ) points. In the dimension of mental health skills, the scores of interpersonal support, cognitive reappraisal and transferred attention were ( 2.58±0.51 ), ( 2.45±0.57 ) and ( 2.82±0.49 ) points, and the score of mental health awareness was ( 3.63±0.47 ) points. A higher level of mental health literacy was seen in women than in men ( 20.64% vs. 17.22%, P<0.05 ) and in urban residents than in rural residents (20.95% vs. 16.23%, P<0.05 ). In addition, there were age- and educational level-specific levels of mental health literacy among residents ( P<0.05 ), and a higher level was seen in residents at ages of 18 to 45 years ( 28.98% ) and with a bachelor degree (40.89% ). Conclusions A high level of mental health literacy is found in residents in Ningbo City. Mental health promotion campaigns are recommended among men, rural elderly residents with a low educational level.

OBJECTIVE: To discuss the quality of reporting in randomized controlled trials (RCTs) of Chinese herbal medicine (CHM), and to provide suggestions for improving the reporting of future clinical studies in this therapeutic area. METHODS: A search of the Cochrane Library was conducted to identify RCTs of CHM. A revised CONSORT checklist designed for CHM clinical studies was implemented. The revised CONSORT checklist contained 63 items, including the following new items added specifically for CHM: (1) "syndrome of disease" based on Chinese medicine theories; (2) rationale of CHM formula; (3) formula composition; (4) preparation form of CHM; (5) quality control of CHM. RESULTS: The overall reporting quality of the RCTs as assessed with the revised CONSORT checklist varied between 19% and 44%, with a median score of 32% (standard deviation 8%). CONCLUSION: The overall quality of reporting of RCTs of CHM evaluated with a revised CONSORT checklist was poor, reflecting the need for improvements in reporting future clinical trials in this area. RECOMMENDATIONS: To improve the quality of reporting of RCTs of CHM, we recommend adopting a revised CONSORT checklist that includes items specific to CHM. We also recommend that editors of CHM journals require authors to use a structured approach to presenting their trials as a condition of publication.

Objective: To evaluate the efficacy and safety of catheter-directed interventional therapy in patients with acute pulmonary embolism(PE). Methods: PE was diagnosed by CT pulmonary angiography(CTPA). After risk stratification, a total of 79 PE patients (age (58.9±14.9) years old)were treated with catheter-directed interventional therapy via pulmonary vessels. The changes of pulmonary hemodynamics were compared before and after treatment. The risk of complications and side effects were observed. Results: The pulmonary artery pressure was changed followed by interventional therapy. The interventional therapy significantly decreased mean pulmonary arterial pressure (mPAP) from (35.3±11.2)mmHg (1 mmHg=0.133 kPa) to (30.0±10.6)mmHg (t=8.803,P<0.05) and the echocardiographic derived right ventricular dimension to left ventricular dimension (RV/LV) ratio from 0.93±0.16 to 0.83±0.15 (t=6.868,P<0.05). The arterial partial pressure of oxygen was increased from (69.0±8.6)mmHg to (75.1±9.9)mmHg (t=8.561,P<0.05) . The oxygen saturation was also increased from (93.9±2.9)% to (95.1±1.9)% at 24 h after the treatment (t=2.621,P<0.05) . Patients were further grouped as high-risk group (n=28) and intermediate risk group (n=51). mPAP and RV/LV ratio were significantly reduced in the two subgroups (all P<0.05) and the range of reduction was more significant in the high-risk group. Five patients experienced minor bleeding complication, 3 patients suffered worsened dispone post procedure and were treated with mechanical ventilation, 1 patient died, and 1 patient developed recurrent PE. Conclusion The catheter-directed interventional therapy improves pulmonary hemodynamics and reduces load of right ventricle both in high-risk or intermediate risk PE patients, this therapy strategy is safe and effective for patients with PE.

Objective: To investigate the sonographic characteristics of papillary thyroid microcarcinoma(PTMC) and the preoperative prediction value for cervical lymphatic metastasis of PTMC. Methods: Three hundred and fifty-eight PTMC patients who were confirmed by pathology and accepted partly or totally thyroidectomy and neck dissection were collected to analyze the sonographic characteristics, all patients were classified according to multifocal carcinoma nodules and solitary carcinoma nodules; cervical lymphatic metastasis or not; the maximum diameter of carcinoma nodules. Univariate analysis and Logistic regression analysis were used. Results: Compared with solitary PTMC, multifocal PTMC was prone to emerge blood flow signals, heterogeneity, cervical lymphatic metastasis(all P<0.05). By univariate analysis, the risk factors of cervical lymphatic metastasis in PTMC were multifocal lesions and the total maximum diameter >1 cm, irregular edge, irregular shape, microcalcification, capsular invasion(all P<0.05). With Logistic regression analysis, the independent risk factors of cervical lymphatic metastasis in PTMC were multifocality and capsular invasion. Combining multifocality and capsular invasion, which area under the ROC(AUC) was 0.807. Conclusions Combining multifocality and capsular invasion significantly improves the risk of cervical lymphatic metastasis in PTMC by ultrasonography.
