Salvia miltiorrhiza Bunge （Lamiaceae） is a medicinal plant widely used in Traditional Chinese Medicine for treating cardiovascular and cerebrovascular diseases. Chloroplasts are double-membrane-bound, chlorophyll-containing organelles and responsible for photosynthesis in plant cells. The structural information of chloroplast genomes serves as the foundation for precise exogenous gene insertion, site selection, and chloroplast genome modification. In this study, a comprehensive analysis and comparison of 125 chloroplast genomes from S. miltiorrhiza and 76 congeneric species were conducted, focusing on sequence characteristics, codon usage bias, simple sequence repeats （SSRs）, contraction/expansion of chloroplast genome boundaries, and phylogenetic relationships, which could provide a theoretical foundation for advancing chloroplast genetic engineering, genetic diversity analysis, molecular breeding, and species identification within the Salvia genus.

Objective : To compare the tooth drift differences between different types of patients after orthodontic extraction for 1.5 months (45 days) without return to the clinic on time for some reasons. Methods: This study has been reviewed and approved by the Ethics Committee, and informed consent has been obtained from patients. A total of 84 patients had bilateral premolars extracted but were not bonded the bracket for some reasons. The upper and lower jaw dental models were cast, scanned, and reconstructed in 3D. Patients were divided into 12 groups based on extraction positions (first premolar or second premolar), jaw types (maxilla or mandible) and vertical facial types (average angle, high angle, or low angle). Multivariate analysis of variance was used to analyze the changes in the following five indicators in different types of patients who were interrupted for 1.5 months after extraction: anterior tooth crowding, width between canines, width between first molars, tooth extraction space, and overbite of anterior teeth. Results : The tooth extraction position, jaw type and vertical facial type had an effect on the reduction in tooth extraction space and anterior tooth crowding before and after the sudden emergent state (1.5 months after tooth extraction) (P<0.001), and the tooth extraction position and vertical facial type had an effect on the increase in anterior tooth overbite (P<0.001). The drift of bilateral adjacent teeth was greater in patients with first premolars extracted than in those with second premolars extracted (P<0.001), and the drift of bilateral adjacent teeth in the maxilla was larger than that of the mandible (P<0.001). The drift of bilateral adjacent teeth in patients with high angles was more obvious than that of patients with average angles and low angles (P<0.001). Conclusion For orthodontic patients who have maxillary tooth extraction, first premolar extraction, and even high angles in the vertical facial type, the bilateral adjacent teeth are easier to drift, orthodontic treatment should be carried out soon after extraction, and attention should be given to anchorage control.

Objective:To control the pandemic of coronavirus disease 2019 (COVID-19) effectively, strict isolation measures have been taken in China. Suspected patients must be isolated, and the confirmed patients specifically are isolated in negative-pressure isolation rooms. During the isolation, patients face difficulty in adapting to their surrounding environment, worry about the prognosis of the disease, lack confidence in treatment, separate from their families, and have a sense of distance from medical staff. Isolated patients may possess the feelings of negativity, including loneliness, anxiety, depression, insomnia, and despair. Hence, to reduce the risk of adverse psychological outcomes,"family member-like"care strategies were developed and implemented to solve problems associated with the COVID-19 pandemic. This study aims to examine whether using"family member-like"care strategies can improve psychological resilience and reduce depression, anxiety, and stress symptoms among patients with COVID-19 in an isolation ward.Methods: A quasi-experimental design was used to evaluate the"family member-like"care strategies for adult patients with COVID-19 in an isolation ward. COVID-19 patients in the Xiangya ward of the West District of the Union Hospital of Tongji Medical College of Huazhong University of Science and Technology in Wuhan, Hubei province, were included in this study from February 9 to March 20, 2020. Healthcare providers who volunteered as family members were assigned to patients. They practiced one-to-one care and provided continuous and whole care for the patients who were from admission to discharge. Connor-Davidson Resilience Scale-10 (CD-RISC-10) and Depression Anxiety Stress Scale-21 (DASS-21) were used to evaluate the resilience and psychological status of COVID-19 inpatients upon hospital admission, 2 weeks after admission, and at their discharge from the hospital. Results: The questionnaire response rate of the"family member-like"strategies was 100％. Of the 60 patients, 39 (65.0％) were male, and 21 (35％) were female. The hospital stay was (27.5±3.5) days. All the 60 patients were cured and discharged without any death and serious complications. The total scores for CD-RISC were 8.83±6.86 at admission, 29.13±5.42 at 2 weeks after admission, and 33.87±6.14 at discharge, which were significantly improved at the 2 follow-ups (F=404.564, P<0.001). Multivariate analysis and repeated measurements also indicated that patients experienced significant improvements in tenacity (F=360.839, P<0.001), strength (F=368.217, P<0.001), and optimism (F=328.456, P<0.001) at the 2 follow-ups. The total scores of DASS-21 were 49.27±11.30 at admission, 30.77±16.71 at 2 weeks after admission, and 4.17±11.03 at discharge, and the scores were significantly decreased at the 2 follow-ups (F=270.536, P<0.001). Multivariate analysis and repeated measurements also indicated that patients experienced significant decreases in depression (F=211.938, P<0.001), anxiety (F=285.592, P<0.001), and stress (F=287.478, P<0.001) at the 2 follow-ups.Conclusion:"Family member-like"strategies had positive effects on improving psychological resilience and reducing the symptoms of anxiety and depression of COVID-19 patients. It might be an effective care method for COVID-19 patients. It should be incorporated into emergency care management to improve care quality during public health emergencies of infectious diseases.

Objective:To explore the effectiveness and safety of tirofiban in patients with reocclusive ischemic stroke after intravenous thrombolysis with alteplase.Methods:Eighty-four patients with re-occlusive ischemic stroke after intravenous thrombolysis with alteplase, admitted to our hospital from January 2018 to May 2020, were prospectively chosen; these patients were divided into tirofiban group and routine (non-tirofiban) group ( n=42). In addition to thrombolysis, patients in the routine group received intensive lipid-lowering, collateral circulation improvement, blood glucose control, and early rehabilitation therapy; after thrombolysis for 24 h, patients without intracranial hemorrhage were given oral aspirin, 0.1 g/d, for 90 d. After thrombolysis and re-occlusion, patients in the tirofiban group were intravenously pumped with 0.4 μg/(kg·min), which was changed to 0.1 μg/(kg·min) after 30 min for 24 h; at 24 h after thrombolysis, brain CT was reexamined: tirofiban was discontinued for patients with intracranial hemorrhage, and intravenous pumping of tirofiban was continued for patients without intracranial hemorrhage for 24 h. Effectiveness was evaluated by comparing the general clinical data, National Institutes of Health Stroke Scale (NIHSS) scores 7 d after treatment, and modified Rankin Scale (mRS) scores 90 d after treatment between the two groups. Safety was assessed by comparing the intracranial hemorrhage, symptomatic intracranial hemorrhage, and mortality within 90 d of treatment between the two groups. Results:There were no significant differences in age, gender, underlying diseases, risk factors, baseline NIHSS scores, time from onset to start of treatment, infarction sites, and TOAST classification between the 2 groups ( P>0.05). NIHSS scores 7 d after treatment ([10.05±4.73] min vs. [7.93±4.68] min), mRS scores 90 d after treatment (3.48±1.48 vs.2.55±1.93), and good prognosis rate 90 d after treatment (21.4% vs. 42.9%) showed significant differences between the routine group and tirofiban group ( P<0.05). In terms of safety, there were no significant differences in intracranial hemorrhage rate (4.76% vs. 7.14%), symptomatic intracranial hemorrhage incidence (2.38% vs. 2.38%) and mortality (2.38% vs. 2.38%) between the 2 groups ( P>0.05). Conclusion:It is safe and effective for tirofiban in patients with re-occlusive ischemic stroke after intravenous thrombolysis with alteplase.

Radiotherapy is the most common treatment for nasopharyngeal carcinoma, and the radiotherapy technique is essential for the prognosis of nasopharyngeal carcinoma. Due to the complexity of the structure of the intensity-modulated device and the accuracy of the clinical requirements of radiotherapy, it is inevitable that higher requirements will be imposed on the process of intensity-modulated radiotherapy. Currently, gaps exist in the radiotherapy equipment and personnel qualification among radiotherapy units, and thus the homogenization in the radiotherapy remains to be strengthened in China. With the application of radiotherapy information management system, digital medicine and artificial intelligence technologies in the field of radiotherapy, the original process fails to meet the application needs of the new precise radiotherapy technology. Therefore, this process is designed based on the existing radiotherapy procedures for nasopharyngeal carcinoma in combination with the latest developments in the field of radiotherapy, aiming to establish a novel standard process recommendation, ensuring the standardization and homogenization of radiotherapy and achieve the individualized intensity-modulated radiotherapy for nasopharyngeal carcinoma patients.

Exosome is a kind of biological membrane structure at nanometer level. It is secreted by various cells in the body and widely distributed in most body fluids, such as saliva, blood, and milk. Biological active substances, including mRNAs, microRNAs, cytokines, and transcription factor, have been identified in the exosomes. MiRNAs are short and non-coding RNAs that modulate gene expression at the posttranscriptional level. MiRNAs extensively involves in henogenesis, cell proliferation and apoptosis. With various biological functions, exosome-derived miRNAs can not only be served as biomarkers to diagnose tumor, neurological diseases and mental disorders, but also possess potential as therapeutic targets.
