Objective:To compare the clinical efficacy and adverse events of different postoperative radiotherapy strategies (adjuvant radiotherapy versus salvage radiotherapy) and different irradiation fields (prostate bed versus prostate bed + pelvic radiation) in patients after radical prostatectomy for prostate cancer.Methods:This retrospective analysis included clinical data from 115 patients with localized or locally advanced prostate cancer who received intensity-modulated radiotherapy (IMRT) after radical prostatectomy at Beijing Hospital between March 2014 and September 2023. Among them, 40 patients received adjuvant radiotherapy, and 75 received salvage radiotherapy. And 74 patients received irradiation to both the prostate bed and pelvic (prostate bed + pelvic radiation group), while 41 patients received irradiation to the prostate bed alone (prostate bed irradiation group). Comparison was made between the adjuvant radiotherapy group and salvage radiotherapy group, as well as between prostate bed + pelvic radiation group and prostate bed irradiation group, in terms of overall survival (OS), progression-free survival (PFS), locoregional recurrence-free survival (LRRFS), and the incidence of adverse events. Clinical characteristics were compared using the chi-square test. Survival rates were calculated using the Kaplan-Meier method and compared using the log-rank test. Prognostic factors affecting survival were analyzed using Cox multivariate regression.Results:The median follow-up duration was 73.1 months. The 5-year OS, PFS and LRRFS rates for the entire cohort were 96.4%, 86.4%, and 93.2%, respectively. A total of 59 patients (51.3%) experienced grade 1-2 acute radiotherapy-related adverse events, while 43 patients (37.4%) experienced grade 1-2 late radiotherapy-related adverse events. No grade ≥ 3 late adverse events were observed. There were no statistically significant differences in OS, PFS, or LRRFS between the adjuvant and salvage radiotherapy groups ( P = 0.807, 0.996, and 0.976, respectively), or in the incidence of grade 1-2 acute or late adverse events ( P > 0.05). The OS rate in the prostate bed + pelvic radiation group was significantly lower than that in the prostate bed irradiation group ( P = 0.036), while no significant differences were found in PFS or LRRFS ( P = 0.109 and 0.190, respectively), or in the incidence of grade 1-2 acute or late adverse events ( P > 0.05). Multivariable analysis showed no statistically significant differences in OS, PFS, or LRRFS between the adjuvant and salvage radiotherapy groups, or between the prostate bed and prostate bed + pelvic irradiation groups ( P = 0.756, 0.341, 0.605; 0.938, 0.987, 0.605, respectively). Conclusions:In the era of modern IMRT, both adjuvant and salvage radiotherapy, as well as prostate bed and prostate bed + pelvic irradiation, demonstrate similar efficacy and safety profiles after radical prostatectomy for prostate cancer. Treatment outcomes were favorable, and adverse events were minimal.

[Objective]To explore the academic characteristics and the current status of active inheritance of the acupuncture and moxibustion schools in northern Zhejiang.[Methods]Through literature search,data query,personnel interview and other ways,collect the relevant records of acupuncture and moxibustion in northern Zhejiang,sort out the representative schools and summarize their common academic characteristics.[Results]Upon reviewing the literature,it was discovered that the acupuncture and moxibustion schools in northern Zhejiang had a long and storied history,holding a significant position within the academic system of the"Xiushui medical school".Through historical medical research and interviews,it was summarized that the acupuncture and moxibustion in northern Zhejiang possessed five major academic characteristics:precise acupoint selection,diligent study of classics,skillful application of techniques,compassionate medical practice and emphasis on moxibustion therapy.However,the schools faced challenges such as slow transmission,traditional methods and limited dissemination scope during the process of inheritance.[Conclusion]The acupuncture and moxibustion schools in northern Zhejiang have demonstrated distinct academic characteristics and potential for intergenerational innovation in acupoint theory,manual skills and humanistic care.Their inheritance practices have deepened the academic connotations of the"Xiushui medical school".In the future,it is essential to enhance the current status of active inheritance through modern technology and communication methods to promote the widespread dissemination and sustainable development of the academic ideas of northern Zhejiang acupuncture and moxibustion.

Objective To evaluate the role of remimazolam in lipopolysaccharide(LPS)-induced M1 microglial polarization and its relationship with Toll-like receptor 4(TLR4).Methods BV2 mi-croglia cells were randomly divided into 5 groups(n=20):control group,LPS group(1 μg/ml for 24 h),remimazolam+LPS group(remimazolam group,pretreated with 100 μg/ml remimazolam for 20 min followed by LPS),remimazolam+LPS+Neoseptin-3 group(agonist group,50 pmol Neoseptin-3 dissolved in DMSO),and remimazolam+LPS+DMSO group(agonist control group).The contents of TNF-α and IL-1β in the supernatant were detected by ELISA.The expres-sion of M1 microglia markers,inducible nitric oxide synthase(iNOS)and TLR4 at mRNA.Immu-nofluorescence staining was employed to identify the location of iNOS.Results When compared to the control group,the contents of TNF-α and IL-1β in the supernatant and the expression of iNOS[(14.757±0.986)％vs(1.561±0.08)％]and TLR4 at mRNA and protein levels were sig-nificantly higher in the other four groups(P＜0.05).Remimazolam treatment reversed the increa-ses of the TNF-α and IL-1β contents in the supernatant and mRNA and protein expression of iNOS[(3.767±0.364)％vs(14.757±0.986)％]and TLR4 induced by LPS(P＜0.05).In addi-tion,remimazolam agonist Neoseptin-3 restored the effects of LPS on above molecules[iNOS:(6.827±0.642)％vs(3.767±0.364)％,all P＜0.05].But,there were no statistical differences in above molecules between the agonist group and agonist control group(P＞0.05).Conclusion The mechanism by which remimazolam inhibits LPS-induced M1 microglial polarization is related to down-regulation of TLR4 expression.

Pulmonary blast injury has become the main type of trauma in modern warfare, characterized by externally mild injuries but internally severe injuries, rapid disease progression, and a high rate of early death. The injury is complicated in clinical practice, often with multiple and compound injuries. Currently, there is a lack of effective protective materials, accurate injury detection instrument and portable monitoring and transportation equipment, standardized clinical treatment guidelines in various medical centers, and evidence-based guidelines at home and abroad, resulting in a high mortality in clinlcal practice. Therefore, the Trauma Branch of Chinese Medical Association and the Editorial Committee of Chinese Journal of Trauma organized military and civilian experts in related fields such as thoracic surgery and traumatic surgery to jointly develop the Clinical treatment guideline for pulmonary blast injury ( version 2023) by combining evidence for effectiveness and clinical first-line treatment experience. This guideline provided 16 recommended opinions surrounding definition, characteristics, pre-hospital diagnosis and treatment, and in-hospital treatment of pulmonary blast injury, hoping to provide a basis for the clinical treatment in hospitals at different levels.

OBJECTIVE： To establish a determination method for the concentration of cajanonic acid A （CAA） in liver microsome incubation system， and to compare the metabolism characteristics of it in different species of liver microsomes. METHODS： CAA was dissolved in liver microsome incubation system of rat， Beagle dog and human initiated by reduced nicotinamide adenine dinucleotide phosphate （NADPH）， and was incubated in water at 37 ℃. The reaction was terminated with acetonitrile at 0， 5， 10， 15， 30， 45 and 60 min， respectively. Using genistein as internal standard， the concentration of CAA in  different incubation systems was determined by UPLC-MS/MS. The determination was performed on Waters BEH C18 column with mobile phase consisted of water （containing 0.1％ formic acid）-acetonitrile （containing 0.1％ formic acid） （45 ∶ 55， V/V） at the flow rate of 0.25 mL/min. The column temperature was 30 ℃， and the sample size was 2 μL. The electrospray ionization source was used to the select reaction monitoring mode for negative ion scanning. The ion pairs for quantitative analysis were m/z 353.14→309.11 （CAA）， m/z 269.86→224.11 （internal standard） respectively. The residual percentage and enzymatic kinetic parameters of CAA in different incubation systems were calculated according to the mass concentration of CAA at 0 min. RESULTS： The linear range of CAA was 0.05-20 μg/mL； the limit of quanti- tation was 0.05 μg/mL， and the lowest detection limit was 0.01 μg/mL. RSDs of intra-day and inter-day were lower than 10％； relative errors ranged －4.83％-8.94％； extraction method and matrix effect did not affect the determination of the substance to be measured. At 60 min of incubation， residual percentages of CAA in rat， Beagle dog and human liver microsomes were（62.79±9.99）％，（64.07±11.59）％，（96.66±5.71）％， respectively. The half-life period （72.19， 68.61 min） of CAA in rat and Beagle dog liver microsomes were significantly shorter than human liver microsome （364.74 min）. The clearance rates [0.019 2， 0.020 2 mL/（min·mg）] were significantly higher than human liver microsome [0.003 8 mL/（min·mg）] （P＜0.05）. CONCLUSIONS： Established UPLC-MS/MS method is simple， rapid， specific and sensitive， and can be used for the determination of CAA concentration in liver microsome incubation system and the study of metabolism stability in vitro. The stability of CAA metabolism in rat and Beagle dog liver microsomes are poorer than human liver microsome.
