The modernization of the governance system for traditional Chinese medicine （TCM） constitutes the institutional cornerstone for advancing the high-quality development of the TCM sector in China. Drawing on focus group discussions with TCM administrative leaders， experts， and scholars who examined the connotations， implementation pathways， problems， and challenges associated with the modernization of TCM governance and governance capacity， this study employed a constructivist grounded theory methodology. Through systematic procedures including initial coding， focused coding， axial coding， and theoretical coding， the study develops a theoretical framework for the modernization of the TCM governance system， with "governance goals - governance philosophy - collaborative governance - institutional systems" as the core. Building upon this framework， the study proposes several implementation strategies for modernizing TCM governance system， such as prioritizing people's health， fostering cultural confidence in TCM， enhancing multi-stakeholder collaboration， and comprehensively improving the institutional architecture of TCM. These findings offer theoretical insights to support the advancement of a modernized TCM governance system.

SMART (S = Specific, M = Measurable, A = Attainable, R = Relevant, T = Time-bound) principle is a goal-setting theory that includes five aspects: clarity, measurability, achievability, relevance, and timeliness. This online nutrition practice course introduces SMART principle teaching methodology to help students build autonomous learning capabilities. Questionnaires were used to learn about students' satisfaction. We also evaluated the students' practical skills by measuring students' self-perception of collaborative attitude, leadership, communication skills and intellectual challenge abilities before and after the course. The results found that 89.7% (26/29) of the students were generally satisfied with this online nutrition practice course. About 86.2% (25/29) of the students thought online learning was acceptable. By the end of the course, students' self-perception of collaborative attitude, leadership, communication skills and intellectual challenge abilities were increased by 7%, 13%, 14% and 10%, respectively. This online nutrition practice course indicates that SMART principle can help students build autonomous learning capabilities by setting practical, specific and time-limited teaching objectives, which improves students' learning enthusiasm and effectively enhances the practice ability of students.

Objective:To investigate the role of growth arrest specific protein 6 (Gas6) in regulating macrophage polarization in wound healing.Methods:Clean male B6 mice were randomly(random number) divided into the normal group, skin defect group, skin defect group + normal saline group (PBS group), skin defect + Gas6 (1 μg) group, skin defect + Gas6 (5 μg) group, and skin defect + Gas6 (10 μg) group. Ten mice in each group were used to observe the healing of skin wounds. Macrophages were isolated from the wound tissues of the remaining 6 mice on the fifth day after modeling. The levels of IL-6 and IL-10 were detected by enzyme-linked immunosorbent assay (ELISA), the mRNA expression levels of arginase-1 (Arg-1) and inducible nitric oxide synthase (iNOS) were detected by RT-PCR, and flow cytometry was used to detect the expression of M1 marker CD197, M2 marker CD163 and F4/80. HE staining was used to detect the pathological changes of skin wounds. Masson staining was used to analyze the granulation tissue and collagen deposition.Results:Scab began to form on the surface of the wound on the third day after the skin defect model was established. The wound area of the Gas6 treatment group was smaller than that of the PBS group, and the wound healing was better than that of the PBS group. Compared with the normal group, the proportion of CD197 in macrophages of the skin defect group was significantly increased ( P=0.00 49), the proportion of CD163 and F4/80 double positive was significantly decreased ( P=0.00 86), the level of IL-6 was significantly increased ( P=0.00 13), the level of IL-10 was significantly increased ( P=0.00 14), the level of iNOS mRNA was significantly increased ( P=0.00 8), and Arg-1 was significantly increased in the skin defect group The mRNA level was significantly decreased ( P=0.01 21), and the inflammatory infiltration was aggravated. Compared with the PBS group, the proportion of CD197 in the Gas6 treatment group was significantly decreased ( P=0.00 0), the double positive rates of CD163 and F4/80 were significantly increased ( P = 0.00 0), the level of IL-6 was significantly decreased (P = 0.00 0), the level of IL-10 was significantly increased ( P=0.00 03), the level of iNOS mRNA was significantly decreased ( P=0.00 18), the level of Arg-1 mRNA was significantly increased ( P=0.00 1), and the number of inflammatory cells and the number of collagen fibers were increased. Conclusions:Gas6 can promote the transformation of macrophages from M1 to M2 in mice with skin defect, which is beneficial to the wound healing of skin defect.

From May 2013 to March 2020, 25 patients with acute necrotizing fasciitis were admitted to Beijing Chaoyang Emergency Rescue Center, including 18 males and 7 females, aged 7 to 78 years. The lesions were mainly located in the lower extremities, with the original lesion areas ranging from 20 cm×15 cm to 83 cm×42 cm. After admission, comprehensive systemic treatment was performed, the lesion area was cut open and drained as soon as possible, and the necrotic tissue was removed. Vacuum sealing drainage was performed when the necrotic tissue in the wound was reduced. The wounds were directly sutured or repaired with thin split-thickness skin grafts taken from head and/or thigh or local skin flaps after the wounds were improved. The skin grafts and flaps survived well after surgery, and the wound was completely closed. None of the 25 patients had amputation. A total of 21 patients were followed up for more than half a year, showing no recurrence of acute necrotizing fasciitis and no difference in the function of their injured limb after the wound healing than before the onset.

Objective To evaluate the clinical efficacy and adverse events of intensity-modulated radiotherapy ( IMRT ) in the treatment of intermediate risk localized prostate cancer, and analyze the significance of prostate-specific antigen ( PSA) level changes. Methods Clinical data of 66 patients with intermediate risk localized prostate cancer admitted to our hospital between 2007 and 2018 were retrospectively analyzed. Sixty patients were treated with endocrine therapy before radiotherapy. The radiation field covered the pelvic lymph node drainage area in 6 cases. Forty-seven patients received image-guided radiotherapy ( IGRT) . The median dose in the prostate and seminal vesicle was 78 Gy and 48 Gy in the pelvic lymph node drainage area. The survival rate was calculated using the Kaplan-Meier method. Results The median age was 77 years. The median follow-up time was 71. 3 months. The 5-year sample size was 47. The 3-and 5-year overall survival (OS) was 98％ and 90％.The 3-and 5-year cancer-specific survival (CSS) was 100％ and 93％.The 3-and 5-year biochemical relapse-free survival was 97％ and 86％. The mean time of PSA declining to the nadir was 5. 83 months. The median level of PSA nadir was 0. 06 ng/ml after IMRT. The incidence of grade I andⅡearly adverse events in the urinary system was 38％ and 6％. The incidence of grade I andⅡearly adverse events in the gastrointestinal system was 21％ and 3％. The incidence of grade I andⅡadvanced-stage adverse events in the urinary system was 9％ and 2％. The incidence of grade I advanced-stage adverse events in the gastrointestinal system was 5％. Conclusions IMRT yields high clinical efficacy in the treatment of intermediate risk localized prostate cancer with a low risk of adverse events in the early and advanced stage. The monitoring of PSA after IMRT contributes to the assessment of clinical prognosis.

Objective To analyze the data from intensity-modulated radiotherapy ( IMRT) for prostate cancer guided by kilovoltage cone-beam computed tomography (CBCT), and to provide a clinical basis for selecting the optimal image registration method and reasonable target volume margins.Methods A total of 16 patients with prostate cancer who received radical IMRT were enrolled, and CBCT for online position verification was performed 214 times.The images were obtained after conventional skin marking and laser alignment, and automatic registration, bone registration, soft tissue registration, and manual registration were performed for CBCT images and planned CT images.The differences between these four registration methods were evaluated, and the margins for extending clinical target volume into planning target volume (PTV) were calculated.Results The setup errors in left-right, anterior-posterior, and cranial-caudal directions for automatic registration, bone registration, soft tissue registration, and manual registration were-0.6±2.8 mm/-0.6±4.5 mm/-0.6±3.8 mm,-0.7±2.7 mm/-0.9±4.5 mm/-0.8±4.1 mm,-0.8± 2.6 mm/-0.3±4.4 mm/-1.1±4.0 mm, and-0.6±2.9 mm/-0.7±5.1 mm/-0.9±3.9 mm, respectively. There were no significant differences between the four registration methods.The margins for extension in the left-right, anterior-posterior, and cranial-caudal directions were calculated as 4.7 mm, 5.2 mm, and 6.5 mm, respectively.Conclusions With a comprehensive consideration of various factors, a default setting of automatic registration and manual fine adjustment is appropriate for CBCT-guided radiotherapy for prostate cancer.The margins for extension in the left-right, anterior-posterior, and cranial-caudal directions are 4.7 mm, 5.2 mm, and 6.5 mm, respectively.

Objective To observe the motions of the rectum and bladder by image?guided radiotherapy ( IGRT) and to analyze their impact on treatment. Methods Eighteen patients with prostate cancer undergoing intensity?modulated radiotherapy ( IMRT) were enrolled in the study and 247 cone?beam computed tomography ( CBCT) images were obtained from this study. The clinical target volume, bladder, and rectum were contoured on all simulated CT and CBCT to examine their volume and position changes. The dose distributions were recalculated based on the data of the x?, y?, and z?axis setup errors. The doses to planning target volume ( PTV) and organs at risk were calculated in the replanning, and their impact on treatment was analyzed. Comparison of the planning and replanning results was made by paired t?test. The effects of displacements and volumes of the bladder and rectum on target doses were analyzed by Pearson correlation method. Results Great changes in the volumes of the bladder and rectum were observed during the treatment. For the planning and replanning results, PTVD95% was 7777. 37 cGy vs. 7628. 56 cGy ( P=0. 027), PTV Dmin was 87. 91 cGy vs. 83. 35 cGy (P=0. 000), and RVP was 5. 89% vs. 8. 31%(P=0. 000). There were correlations between PTVD95% and the motions of the bladder and rectum, with correlation coefficients of 0. 296 and 0. 177, respectively. The correlation coefficient between rectal volume and PTVD95% was 0. 115, indicating a certain correlation. There is a certain correlation between and PTV Dmin and bladder volume, with a correlation coefficient of?0. 128. Conclusions The recovery of the state during localization for the bladder and rectum, especially the latter, has great significance to ensure the target dose and reduce exposure of the rectum in the IMRT for prostate cancer.

Objective To compare the ventilatory effects between three-way laryngeal mask airway (TLMA)and tracheal catheter (TC) on hemodynamics, respiratory function and stress responses on patients during bronchoalveolar lavage (BAL). Method Forty patients scheduled for BAL under general anesthesia were divided (stratified sampling) into either TLMA group (group T,n = 20) or TC group (group C, n = 20) according to the stratified sampling principle. SpO2, SBP, DBP and HR were measured in 5 min after entering the operating theater (To), just before inserting TLMA or TC(T1), immediately after inserting TLMA or TC(T2) ,3 min(T3), 5 min(T4), 10 min(T5)after mechanical ventilation, 10 min(T6),20 min(T7), 30 min(T8)during the course of BAL,immediately after extubating TLMA or TC (T9)and 3 min after extubating TLMA or TC (T10). The tidal volume (VT), peak inspiratory airway pressure (Ppeak) and end expiratory CO2 pressure(PETCO2)were recorded at T2,T4,T6,T7, T8, T10. The venous blood samples were taken at T0, T2, T3, T4, T6, T9, T10 for the measurements of epinephrine(AE), norepinephrine(NE)and dopamine (DA) levels with high performance liquid chromatography.Data were dealt with SPSS version 10.0 statistic software. The variables of hemodynamics and stress responses were analyzed with ANOVA of repeating test data. P ＜ 0.05 means the difference in statistical significance. Results In group C, SBP, DBP and HR were significantly higher than those in group T at T2 ,T3 ,T9 (P ＜ 0.05). In group C, the levels of Ppeak were significantly higher than those in group T at T6 ,T7 ,T8 (P ＜ 0.05), and the concentrations of AE, NE and DA were also significantly higher in group C than those in group T at T2, T3 and T9 (P ＜0.05). Conclusions Ventilation with TLMA in patients during BAL is better than TC in respects of keeping stable ventilation, stable hemodynamics and producing less stress responses.

Three-way laryngeal mask airway (tLMA) was used in 31 patients aged 4-68 yr, weighing 10- 79 kg undergoing tracheal foreign body removal under general anesthesia. Anesthesia was induced with propofol 3 mg/kg, vecuronium 0.12 mg/kg and remifentanil 0.4 μg/kg. tLMA was inserted. The patients were mechanically ventilated. Anesthesia was maintained with iv infusion of propofol 2 mg . Kg-1 ? H-1, vecuronium 0.08 mg·kg-1·h-1 and remifentanil 0.15 μg·kg-1 ·min-1 . Radial artery was cannulated for BP monitoring and blood sampling. The operation time was 6-34 min and mechanical ventilation time 19-45 min. There was no significant change in SP, DP, HR, VT, Ppeak and Ppeak CO, during operation as compared with the baseline values before anesthesia. SpO2 was significantly increased at T2-6. PCO2, PO2 and O2sat were obviously improved after tLMA was used. All the patients emerged bom anesthesia within 30 min after operation. No aspiration, obvious gastrointestinal inflation, and pharyngeal and laryngeal edema and injury occurred. Mild agitation occurred in a short time during the recovery period in one patient. No complication occurred.
