China is currently in an accelerated stage of population aging, and brain diseases pose a significant threat to the health of the elderly. " Preventing brain aging and maintaining brain health" has become a high-level goal of healthy aging. During the process of aging, the physiological and psychological states of elderly people change, making them prone to nervousness and exhaustion, which can disturb the brain spirit, damage the brain collaterals, and severely endanger brain health. Starting from the holistic view of cultivating both body and spirit in traditional Chinese medicine, based on the physical and mental characteristics of the elderly, this paper applies the concept and method of " relaxation and tranquility" in the protection of elderly brain health, focusing on maintaining relaxation and tranquility in both physical and mental aspects. Specific measures include emphasizing subjective consciousness, relaxing the heart and calming down; utilizing the daoyin method, relaxing the body and calming down, combining relaxation and tranquility, cultivating both body and spirit to prevent diseases and protect the brain, which enables the elderly to have a healthy mind and body, a sense of happiness and fulfillment, and to age gracefully. Simultaneously, advocating for tranquility is also called " respect" for relaxation, following nature to understand constant changes, and improving one′s ability to think positively in old age, in order to expand ideas for the protection of elderly brain health.

Objective: To analyze the effects of blue light on the formation of kidney stones. Methods: A total of 40 rats were randomly divided into 4 groups：A，B，C，and D，with 10 rats in each group.Rats in groups C and D were administered with a mixture of 10 g/L ethylene glycol，20 g/L ammonium chloride，and 100 g/L calcium gluconate via gavage (2 mL per mouse)，while rats in groups A and B received an equal volume of physiological saline via gavage.From the second day after gavage，rats in groups A and C were subjected to twice-daily blue light irradiation (one hour per session) as an intervention，while rats in groups B and D were subjected to fluorescent lamp irradiation using the same method.After 4 weeks of intervention，the 24-hour urine samples were collected，and the rats were then euthanized for the collection of blood and kidney tissue samples.Serum levels of antidiuretic hormone (ADH)，urinary Ca ，and urinary oxalate (Oxa) were measured.Levels of malondialdehyde (MDA) and superoxide dismutase (SOD) in kidney tissues were detected using ELISA.Von Kossa staining was performed to observe pathological changes in kidney tissues and the presence of calcium salt crystals in the kidneys. Results: Compared with groups A and B，groups C and D showed higher accumulation of calcium salt crystals in renal tissues，as well as elevated levels of ADH，urinary Ca ，urinary Oxa，and MDA in renal tissues, additionally，the SOD level in renal tissues was lower (P<0.05).Compared with group D，group C exhibited higher accumulation of calcium salt crystals in renal tissues，along with increased levels of ADH，urinary Ca ，urinary Oxa，and MDA in renal tissues；conversely，the SOD level in renal tissues was lower (P<0.05). Conclusion: Blue light may increase the formation of kidney stones in rats by promoting the secretion of ADH in serum and oxidative stress in kidney tissues through the brain-kidney axis.

The Compilation Instructions for Expert Consensus on Clinical Application of Dieda Huoxue capsules systematically expound the development methods and evidence-based basis of this consensus. In view of the weak clinical application evidence and ambiguous indications of Dieda Huoxue capsules， the Institute of Basic Research in Clinical Medicine of the China Academy of Chinese Medical Sciences and Wangjing Hospital took the lead and collaborated with 33 experts from 28 medical institutions nationwide. They strictly followed the World Health Organization （WHO） guideline-making norms and the Grading of Recommendations Assessment， Development and Evaluations （GRADE） evidence-grading system and completed the compilation through multidisciplinary cooperation. The workflow included constructing clinical questions （19 items were screened by the nominal group technique）， retrieving evidence （from Chinese and English databases and grey literature）， assessing safety （integrating drug monitoring data and clinical investigations）， and forming recommendations and consensus suggestions （3 recommendations were reached via the GRADE grid method， and 16 consensus suggestions were reached by the majority vote rule）. The results indicate that the consensus clearly states that this medicine （Dieda Huoxue capsules） is applicable to conditions like traumatic injury， blood stasis-induced pain， and sudden lumbar sprains. The recommended dose is 6 capsules each time， twice a day. Combining oral administration with external application can enhance the efficacy， and elderly patients should take the medicine at intervals. Safety monitoring suggests that it should be used with caution in people with a bleeding tendency and those with an allergic constitution. The compilation process involved three rounds of reviews by internal and external experts. Literature analysis， the Delphi method， and clinical applicability tests were employed to ensure methodological rigor. The compilation instructions comprehensively present key aspects such as project approval and registration， conflict-of-interest statements， and evidence evaluation through 12 appendices， providing methodological support for the clinical translation of the consensus. In the future， it will be continuously improved through a dynamic revision mechanism.

Objective To discuss the methods,efficacy,and safety of endovascular treatment for ruptured pseudoaneurysm hemorrhage of internal carotid artery(ICA)after radiotherapy for nasopharyngeal carcinoma(NPC).Methods The clinical data of 21 patients with ruptured pseudoaneurysm hemorrhage of ICA after radiotherapy for NPC,who were admitted to the Affiliated Union Hospital,Fujian Medical University of China,were retrospectively analyzed.The patient's surgical strategies were analyzed,the therapeutic results and the clinical and imaging follow-up results were summarized.Of the 21 patients,covered stent implantation was carried out in 8,stent-assisted coil embolization was employed in 6,and direct occlusion of parent artery was adopted in 7.Results Successful endovascular treatment was accomplished in all the 21 patients.Excellent hemostatic effect was obtained immediately after surgery.Aneurysm neck residue was observed in 2 patients,and aneurysm body residue was seen in one patients.Postoperative bleeding recurred in 5 patients,in 4 of them the bleeding stopped after once more occlusion of the parent artery,and one patient developed internal leakage after covered stent implantation and the bleeding stopped after balloon dilation,and this patient died of unknown cause one month later.One patient developed coma after covered stent implantation,CT scan demonstrated subarachnoid hemorrhage and brain swelling,and this patient showed no improvement after treatment and was self-discharged from hospital.ICA occlusion was seen in 3 patients during follow-up period,and 2 patients did not receive a postoperative follow-up visit.In the 19 patients who were followed up,the mRS score was 0 point(n=9),1 point(n=6),2 points(n=2),5 points(n=1),and 6 points(n=1).Conclusion For the ruptured pseudoaneurysm hemorrhage of ICA after radiotherapy for NPC,endovascular treatment is highly safe with reliable efficacy.The covered stent implantation carries good short-term efficacy,but there are also problems such as aneurysm recurrence,internal endoleak,etc.The direct occlusion of parent artery may have more reliable long-term efficacy.(J Intervent Radiol,2024,33:304-308)

Objective To investigate the protective effect of apigenin on renal tubular epithelial cells(HK-2)induced by hyperglycemia and its potential mechanism.Methods HK-2 cells were incubated with d-glucose to establish an in vitro diabetic nephropathy model.Cell viability,apoptosis and oxidative stress were assessed.The mRNA levels of nuclear factor erythroid-2 related factor 2(Nrf2),heme oxygenase-1(HO-1)and epoxy chloropropane Kelch sample related protein-1(Keap1)were measured by quantitative real-time-PCR(q-PCR).Western blot analysis was performed to measure the protein expression of Nrf2.Results In HK-2 cells,high glucose decreased cell viability in a concentration-and time-dependent manner.Apigenin improved the viability of HK-2 cells under high glucose stress,reduced apoptosis and proinflammatory cytokine production,and inhibited the oxidative stress.Apigenin increased mRNA expression of Nrf2 and HO-1,increased expression of Nrf2 protein and reduced the mRNA level of Keap1.Inhibition of Nrf2 using small interfering RNA(siRNA)abolished the protective effects of apigenin on HK-2 cells under high glucose stress.Conclusion Apigenin treatment can alleviate the damage of HK-2 cells under high glucose stress,and exert the anti-oxidation and anti-inflammation effects through Keap1-Nrf2-ARE pathway.

ObjectiveThis study aimed to evaluate the clinical efficacy of Ruyi Zhenbaowan（RYZBW）in the treatment of initial and early knee osteoarthritis （KOA） through a prospective multicenter，randomized，double-blind，and placebo-parallel controlled trial. MethodFrom October 13^th， 2021 to December 25^th， 2021， 240 KOA subjects meeting the acceptance criteria were enrolled in 15 sub-centers including Wangjing Hospital， Chinese Academy of Chinese Medical Sciences， and they were randomly divided into observation group and control group， with 120 cases in each group. The intervention measures for the observation group were RYZBW + health education， and the intervention measures for the control group were RYZBW placebo + health education. The intervention period in both groups was four weeks， and they were followed up for four weeks after the intervention. The primary outcome measure was the total score of Western Ontario and McMaster University Osteoarthritis Index score （WOMAC score）， and the secondary outcome measures were the response rate of visual scale （VAS） pain score， WOMAC sub item scores （joint pain， joint stiffness， and joint function）， quality of life （SF-12） score， and traditional Chinese medicine （TCM） syndrome score. Result（1） Efficacy evaluation. The marginal model results showed that the observation group was better than the control group in improving the WOMAC total score and WOMAC pain score in the treatment of KOA with RYZBW， and the difference was statistically significant （P<0.05）. There was no significant difference between the two groups in improving VAS score response rate， WOMAC function score， WOMAC stiffness score， SF12-PCS （quality of life-physical health） score， SF12-MCS （quality of life-mental health） score， and TCM syndrome score. （2） Subgroup analysis. ① In terms of VAS score response rate， the response rate of the observation group was higher than that of the control group for subjects with baseline VAS score of （4， 5］， and the difference was statistically significant （P<0.05）. ② In terms of TCM syndrome score， for subjects aged ［56， 60］ and ［61， 65］， the decrease in total TCM syndrome score in the observation group was better than that in the control group， and the difference was statistically significant （P<0.05）. ConclusionTibetan medicine RYZBW has good clinical efficacy in improving WOMAC total score， VAS score response rate， WOMAC pain score， WOMAC function score， and TCM syndrome score for patients with initial and early KOA， which can fill the lack of Tibetan medicine RYZBW in the treatment of KOA and make a demonstration study for the inheritance and development of ethnic medicine.

Objective To investigate the effect of rehabilitation instruction based on resourceful theory on the execution intention of exercise behaviour in patient with the first-episode stroke.Methods From September 2022 to February 2023,a total of 80 inpatients with first-episode stroke from a general hospital in Anhui Province participated in the study.Patients in Wards Ⅰ and Ⅱ were assigned to an intervention group,while those in Wards Ⅲ and Ⅳ were assigned to a control group,with 40 patients per group.The patients in control group received standard interventions,while those in the intervention group were offered with a rehabilitation instruction based on resourceful theory in addition to the standard interventions.Stroke patient rehabilitation exercise behaviour execution intention questionnaire,resourcefulness scale and modified Barthel were employed for assessments before and after the intervention.Results After the intervention,the intervention group showed significantly higher scores inexecutive intention of exercise behaviour,resourcefulness level and daily living activities compared to those in the control group(all P＜0.01).Conclusion Rehabilitation instruction based on the theory of resourcefulness can effectively increase the executive intention of exercise behaviour in the patients with first-episode stroke,improve the resourcefulness thinking levels and enhance the daily living activity of the patients.

Objective To construct the demand model of four types of medical resources including beds in hospi-tal,beds in intensive care unit(ICU),ventilators and medical human resources during the major infectious disease epidemic events,simulate and analyze the treatment of infectious diseases when different medical resources are in short supply.Methods Based on the susceptible-exposed-infectious-recovered(SEIR)model,considering the infec-tivity of infected persons,the susceptibility of the population and the immunity of convalescents,the characteristics of asymptomatic COVID-19 patients and different clinical types,the"COVID-19 infection-hospitalization model"was constructed.By collecting and setting the parameters of disease transmission,clinical course and medical re-source shortage scenarios,an analysis model of allocation and supply of urban medical resources during infectious di-sease epidemic events was initially formed based on Anylogic platform,the supply and demand of medical resources during infectious disease events in different scenarios were analyzed.Results In the non-intervention scenario,the peak time of bed demand was on the 107th day,and the peak value was 160.92 beds per thousand people;the peak time of ventilator demand was on the 122nd day,and the peak value was 5.61 units per thousand people;the peak time of ICU bed demand was on the 117th day,and the peak value was 12.78 beds per thousand people;the peak time of the demand for medical human resources was on the 109th day,and the peak value was 151.12 persons per thousand persons.The simulation results suggested that there were some differences in the impact of different medi-cal resources on the outcome of medical treatment.Conclusion This study constructs an analytical tool for the allo-cation and supply of urban medical resources under the epidemic events of infectious diseases,and the results of mul-tiple simulation experiments suggest that bed resources and medical human resources play more important roles in the outcome of medical treatment.

Aim To investigate the effects of L-argi-nine on spontaneous contraction of rat colon and the relative mechanisms.Methods An organ bath system was use to measure the spontaneous contraction of both longitudinal smooth muscle strips(LMS)and circular muscle strips(CMS).Whole-cell voltage-clamp tech-niques were applied to observe the alterations in cur-rents of L-type voltage-dependent Ca2+channels(VD-CCs),and voltage-gated K+channel(Kv)in single smooth muscle cells(SMCs)from rat colon.Results L-Arginine(1 mmol·L-1)significantly enhanced the spontaneous contraction of both LMS and CMS.The excitatory response to L-arginine was remarkably attenuated by tetrodotoxin(1 mmol·L-1)and atro-pine(1 mmol·L-1),antagonist of muscarinic ACh receptor(mAChR).However,the inhibitor of nitric oxide(NO)synthesis L-NNA(1 mmol·L-1)failed to block the action of L-Arginine.Furthermore,whole-cell patch-clamp recordings showed that L-arginine ac-tivated VDCCs and inhibited Kv channels on SMCs.Conclusions L-Arginine exerts an excitatory effect on colonic motility in a nitric oxide(NO)-independent manner and the stimulatory action of L-arginine is part-ly mediated by mAChR.In addition,VDCCs and Kv channels are both involved in L-arginine-induced exci-tation.
