Objective:To investigate the current status of application of stereotactic body radiation therapy (SBRT) in China, aiming to provide reference for promoting the development of this technology.Methods:From January to March 2024, a questionnaire was designed and distributed online, targeting member units of the Professional Committee of Stereotactic Radiosurgery Treatment, which covers 175 radiotherapy units in 30 provinces and regions nationwide. The survey focused on the current application of SBRT technology and its utilization in the treatment of early-stage non-small cell lung cancer (NSCLC). A statistical description of the survey results was presented.Results:Of 175 questionnaires distributed, a total of 130 valid responses were collected, with an effective response rate of 74.3%. A total of 81.5% (106/130) of the units had implemented SBRT technology, and 99.1% of the respondents believed it was necessary to further promote SBRT technology, yet the actual training rate was only 67.0%. SBRT equipment configuration: there were a total of 267 SBRT equipment, featuring a diverse range of types, with traditional linear accelerators as the mainstays, accounting for 76.0% ( n=203), followed by 12.0% ( n=32) for TOMO, 6.4% ( n=17) for Cyber knife, 3.7% ( n=10) for Gamma knife, and proton/heavy ion equipment at 1.5% ( n=4), respectively. The percentage of units with multi-leaf collimator leaf widths ≤0.5 cm was 93.4% (99/106). The application of SBRT: the first radiotherapy unit commenced SBRT in 2000, and this technology entered a period of rapid growth after 2015, sustaining a steady increase over the past decade; SBRT technology was mainly applied in the brain, lung, liver, bone, adrenal gland, and kidney, with application rates of 97.2%, 94.3%, 86.8%, 71.7%, 56.6%, and 27.4%, respectively, while the application rates for the pancreas, metastatic lymph nodes, and other parts were less than 5%. Current status of SBRT technology application in early-stage NSCLC: 90.6% (96/106) of units had implemented SBRT; pre-treatment multi-disciplinary diagnosis and treatment accounted for 77% (74/96); the proportion of application units for peripheral and central type lung cancer lesions both exceeded 57.3%, whereas the application rate for ultra-central type and lesions > 5 cm lung cancer was less than 30%; there was significant variability in the selection of reference guidelines, dose fractionation patterns, and the concept of central type among units. Conclusions:The development of SBRT technology in China is in a period of steady growth, but several issues such as low training rate and lack of standardization still exist. The survey results provide important reference for clinical training and promotion of SBRT technology in China.

Xiaoqinglong Decoction comes from Shang Han Lun, which is the main treatment for wind chill and fluid retention. It is treated as a classic formula for cold-cough, which syndromes of no sweat but tight pulse, cough, cough with white phlegm, and vomiting. This article discussed the efficacy of Xiaoqinglong Decoction in tonifying yang in lung, which can help transport phlegm, and then cough can be relieved.

Objective To determine the molecular pathway of reconstituted basement membrane extract(BME)embedment in the context of promoting islet cell survival.Methods Mouse islet cells were isolated and embedded in BME for in vitro culture.Caspase-3,integrin-α1 and 5,PDX-1,Akt,FAK and phospho Erk were detected using Western blot.Results Islet cells embedded with BME were partially protected from apoptosis indicated by a lower caspase-3 level and an increased phosphoAkt activity compared with untreated control.In addition,an increase of α3-integrin,FAK protein level and FAK activity were observed as well.Furthermore,the expression of PDX-1 and phosphoErk at the 48 h mark were preserved,suggesting the positive effect of BME to islet activity.Conclusion These results indicate that the embedment of BME construction can up-regulate α3 integrin and its signal transduction,which may improve viability and function of islet cells.
