Abstract: Objective　To explore the epidemiological and clinical characteristics of non-tuberculous mycobacterial(NTM) pulmonary disease in Hainan in recent years, and to provide data support for the prevention and treatment of NTM pulmonary disease. Methods　Medical records of patients diagnosed with NTM pulmonary disease who treated at the Second Affiliated Hospital of Hainan Medical University (Hainan Provincial Tuberculosis Hospital) from January 2018 to December 2022 were collected. The demographics, regional distribution, temporal distribution, distribution of mycobacterial species, clinical symptoms, and radiological imaging changes of these patients were analyzed. Results　A total of 225 confirmed cases of NMT pulmonary disease were collected in this study, with 133(59.1%) female patients outnumbering 92(40.9%) male patients. The disease predominantly affected people over 50 years old, with 192 cases (85.3%), and the major onset age range was 61-<81 years old, with a median age of 63 and an average age of 62. Farmers comprised the majority of the patients, with 112 cases (49.8%). More patients were from the western region (90 cases, 40.0%) than from the central region (76 cases, 33.8%), followed by the eastern region (59 cases, 26.2%). A total of 10 strains were detected from 225 samples, with the most common strains being Mycobacterium intracellulare (92 cases, 40.9%), Mycobacterium chelonae/abscessus(80 cases, 35.6%), and Mycobacterium avium (15 cases, 6.7%), followed by Mycobacterium kansasii (5 cases, 2.2%), Mycobacterium fortuitum (4 cases, 1.8%), and Mycobacterium parascrofulaceum (3 cases, 1.3%). There were 10 cases (4.5%) of mixed infections, including Mycobacterium avium and Mycobacterium intracellulare (8 cases, 3.6%), Mycobacterium intracellulare and Mycobacterium chelonae/abscessus (1 case, 0.4%), and Mycobacterium fortuitum and Mycobacterium chelonae/abscessus (1 case, 0.4%). The primary clinical manifestations of NTM pulmonary disease included cough and sputum (219 cases, 97.3%), hemoptysis (92 cases, 40.9%), fever (61 cases, 27.1%), dyspnea (57 cases, 25.3%), night sweats (52 cases, 23.1%), weight loss (50 cases, 22.2%), and thoracodynia (35 cases, 15.6%). There was no significant difference in symptoms between male and female patients. Pleural thickening (188 cases, 83.6%) and bronchiectasis (151 cases, 67.1%) were the most common imaging changes in NTM pulmonary disease, followed by cavities (93 cases, 41.3%), emphysema (41 cases, 18.2%), and lung damage (28 cases, 12.4%). Male patients were more likely to have lung damage and emphysema, while female patients were more likely to have bronchiectasis. Conclusions　The distribution of NTM species is diverse in Hainan area, with Mycobacterium intracellulare, Mycobacterium chelonae/abscessus, and Mycobacterium avium are dominant species. NTM pulmonary disease and pulmonary tuberculosis have similar clinical features, which requires attention for differentiation in clinical practice.

OBJECTIVE To investigate the effects and mechanism of luteolin on osteogenic repair of bone defects. METHODS The targets and potential pathways of luteolin in the treatment of bone defects were screened by network pharmacology method， and then the top 2 targets were selected by Hub gene screening for molecular docking verification， with binding energy as the evaluation standard. In vitro experiments were conducted on rat bone mesenchymal stem cells （BMSC） and rat umbilical vein endothelial cells （RUVEC）. Phenotypic validation was performed using alkaline phosphatase staining， alizarin red S staining， and in vitro angiogenesis experiments. Western blot assay was used to detect the protein expressions of phosphatidylinositol 3 kinase （PI3K） and protein kinase 1 （Akt1）， so as to validate the mechanism of luteolin on osteogenic differentiation of BMSC and angiogenesis of RUVEC in vitro. RESULTS The results of network pharmacology showed that the effects of luteolin on vascular formation and bone repair in bone defects were mainly related to Akt1， SRC， estrogen receptor 1， epidermal growth factor receptor， cyclooxygenase 2， matrix metalloproteinase 9 targets， and were closely related to PI3K-Akt signaling pathway. The results of molecular docking showed that luteolin binding to Akt1 and SRC proteins was stable. The results of in vitro experiments showed that luteolin could significantly improve the expressions and activities of alkaline phosphatase in BMSC， increased the number of calcium salt deposits and calcified nodules， and promoted calcification of BMSC. Compared with luteolin 0 μmol/L group， the angiogenesis ability of RUVEC was enhanced significantly in luteolin 1， 10 μmol/L groups， the length of blood vessels and the protein expressions of PI3K and Akt1 were significantly increased （P＜0.05 or P＜0.01）； the higherthe concentration， the better the effect. CONCLUSIONS Luteolin may play a role in promoting angiogenesis and bone repair at the fracture site by activating PI3K/Akt signaling pathway and promoting the protein expressions of PI3K and Akt1.

Objective:To analyze and summarize the implementation effect of basic essential surgical training (BEST) course of laparoscopic skills over the past 10 years and the practical experience in updating course content and models.Methods:The pre-class assessment questionnaires, basic laparoscopic operation assessment results, and post-class assessment questionnaires of the students who participated in the BEST course of laparoscopic skills were collected. According to the period of the course construction, the students were divided into two groups, namely students who used the course of single training system in the early stage (traditional group) and students who used the course integrating a variety of training systems after the course model was updated in the later stage (test group). The two groups were compared for the scores of track circle moving, tunnel crossing, and high and low columns, as well as their subjective evaluation of course setting and implementation effect. The t-test, Wilcoxon test, or chi-square test was conducted according to the data type using SPSS 13.0. Results:The time for 150 traditional group students to complete track circle moving, tunnel crossing, and high and low columns was 1.08 min (0.81 min, 1.60 min), 2.20 min (1.60 min, 3.27 min), and 4.86 min (3.28 min, 6.36 min), respectively, while the time for 75 test group students to complete the three operations was 1.27 min (0.87 min, 1.83 min), 2.57 min (1.58 min, 4.07 min), and 4.35 min (2.90 min, 6.42 min), respectively, with no significant difference between the two groups ( P>0.05). In terms of students' subjective evaluation of the course, a higher percentage of the test group students were satisfied with classroom environment, teaching method arrangement, training equipment, training opportunities, helping clinical work, and meeting pre-class expectations than those in the traditional group. Conclusion:The constantly updated BEST course can ensure the training quality of trainees and obtain their higher satisfaction. The benefits of this course in clinical practice can be further verified through long-term follow-up of these trainees.

OBJECTIVE To investigate the role of clinical pharmacists in the treatment of a patient with Epstein-Barr （EB） virus encephalitis. METHODS Clinical pharmacist participated in drug diagnosis and therapy for a patient with EB virus encephalitis. According to the physiological characteristics of the disease and the pharmacokinetic-pharmacodynamic characteristics of antibiotics， clinical pharmacists suggested that the dose should be adjusted as ceftriaxone 2 g， q12 h+meropenem 2 g， q8 h. Based on the uncontrolled infection of the patient， pharmacists suggested that ceftriaxone should be stopped and vancomycin 1 million U and q12 h should be used as alternative therapy. According to the results of etiology， pharmacists suggested that acyclovir should be discontinued and replaced with ganciclovir 5 mg/kg， q12 h. The electrolyte disturbance of the patient may be adverse drug reactions caused by Mannitol injection， it was recommended to stop the drug. RESULTS The clinician followed the advice of the clinical pharmacists. After treatment， the patient improved and was discharged. CONCLUSIONS Clinical pharmacists can carry out pharmaceutical care for patients with EB virus encephalitis， assist physicians in optimizing the treatment plan of patients， and ensure the effectiveness and safety of drug treatment.

Radiation-induced brain injury (RBI) is the most serious complication of head and neck tumor after radiotherapy. The pathogenesis of RBI is complicated, and the clinical course is irreversible, while no effective treatment available. The activation of glial cells is one of the main theories of RBI, and the prevention and treatment of RBI by targeting glial cells is the focus of current research. As a post-transcriptional regulatory factor, microRNA (miRNA) has been confirmed to be involved in regulatingglial cell radiosensitivity, inflammation type transformation, autophagy, exosomatic, long non-coding RNA (lncRNA), circular RNA (circRNA) and other related pathways, thereby mediating the occurrence and development of cascade reaction of inflammatory injury and neurological function repair of central nervous system (CNS) disease. Therefore, the establishment of miRNA - glial regulatory network may provide a new strategy for the prevention and treatment of RBI.
