Objective To explore the effect of remote ischemic conditioning(RIC)combined with binaural beat music(BBM)train-ing in patients with cognitive dysfunction after cerebral infarction.Methods From June,2024 to January,2025,200 patients with cognitive dysfunction after cerebral infarction in the Affil-iated Hospital of North China University of Science and Technology were randomly divided into control group(n=50),RIC group(n=50),BBM group(n=50)and combined group(n=50).All the groups received stan-dardized routine training,RIC group received RIC,BBM group received BBM,and the combined group received RIC+BBM,for 14 days.They were assessed with Montreal Cognitive Assessment(MoCA)and Stroke-Specific Quality of Life Scale(SS-QOL)at baseline,day 14,and day 90.Results Two cases in the control group,four in RIC group,three in BBM group and three in the combined group dropped out.For MoCA scores,the inter-group effect,intra-group effect and interaction effect were all significant(F>13.463,P<0.001).After intervention,on both day 14 and day 90,the score of MoCA was higher in each in-tervention group than in the control group(P<0.05),and was higher in the combined group than in both BBM and RIC groups(P<0.05);and on day 90,it was higher in RIC group than in BBM group(P<0.05).For SS-QOL,the score increased with time in all the groups(χ2>75.182,P<0.001).After intervention,there was signif-icant difference at each time point among four groups(H>18.260,P<0.001).On day 14 and day 90,the score of SS-QOL was higher in the combined group than in the control and BBM groups(|Z|>3.149,P<0.05);on day 90,the score was higher in RIC group than in the control group(|Z|=3.590,P<0.05),and it was higher in the combined group than in RIC group(|Z|=3.186,P<0.05).Conclusion RIC,BBM and their combination all improved cognitive function after cerebral infarction.RIC was superior to BBM,and the combined intervention yielded the greatest benefit.Both RIC and the combined intervention im-proved quality of life,with the combined approach being the most effective.

Objective:To develop and validate a perioperative oral care protocol for patients undergoing oral vestibular approach endoscopic thyroid cancer radical surgery, providing practical guidance for clinical nursing.Methods:The protocol was constructed through literature analysis and Delphi expert consultation. A prospective non-randomized controlled study was conducted using convenience sampling, enrolling 60 patients who underwent oral vestibular approach endoscopic thyroid cancer radical surgery at the First Affiliated Hospital with Nanjing Medical University Thyroid Center between August 2023 and May 2024. Participants were divided into control group (from August to December, 2023) and experimental group (from January to May, 2024) based on admission dates with 30 cases in each group. The control group received routine care, while the experimental group received the developed oral care protocolin on the basis of the control group. Postoperative pain scores, mouth-opening difficulties, and oral cleanliness were compared on days 1, 3, and 7 after surgery.Results:The final protocol comprised 7 first-level indicators (team collaboration, health education, preoperative oral assessment, preoperative management, intraoperative management, postoperative management, and discharge follow-up), 17 second-level indicators, and 49 third-level indicators. The control group had 4 males and 26 females, with an age of (29.57 ± 5.34) years; the experimental group had 6 males and 24 females, with an age of (29.87 ± 6.25) years. On postoperative days 1, 3, and 7, the pain scores were 3.87 ± 1.01, 3.30 ± 0.92, and 2.53 ± 0.68 in the control group and 3.20 ± 0.87, 2.10 ± 0.76, and 1.50 ± 0.51 in the experimental group, respectively. The differences between the two groups were statistically significant ( t = 2.89, 5.12, 6.34, all P<0.05). For mouth-opening difficulties, the control group had 6, 13, and 15 patients with grade I on postoperativedays 1, 3, and 7, respectively, while the experimental group had 10, 20, and 25 patients with gradeⅠ. The control group had 20, 14, and 14 patients with gradeⅡonpostoperative days 1, 3, and 7, respectively, while the experimental group had 17, 10, and 5 patients with gradeⅡ. The control group had 4, 3, and 1 patients with grade Ⅲ on postoperative days 1, 3, and 7, respectively, while the experimental group had 3, 0, and 0 patients with grade Ⅲ. There were 0 cases in both groups with grade Ⅳ. The differences between the two groups on postoperative days 3, and 7 were statistically significant ( χ2 = 10.45, 18.67, both P<0.05). For oral cleanliness, the control group had 3, 4, and 5 patients with excellent cleanliness on postoperative days 1, 3, and 7, respectively, while the experimental group had 11, 16, and 19 patients with excellent cleanliness. The control group had 20, 22, and 23 patients with good cleanliness on postoperative days 1, 3, and 7, respectively, while the experimental group had 18, 13, and 10 patients with good cleanliness. The control group had 7 (23.33%), 4 (13.33%), and 2 (6.67%) patients with poor cleanliness on postoperative days 1, 3, and 7, respectively, while the experimental group had 1 (3.33%), 1 (3.33%), and 1 (3.33%) patients with poor cleanliness. The differences between the two groups were statistically significant ( χ2 = 9.19, 11.32, 16.68, all P<0.05). Conclusions:The developed perioperative oral care protocol is scientifically sound, feasible, and practical. Following the intervention, significant decreases in pain scores, alleviation of trismus symptoms, and marked improvements in oral cleanliness were observed in patients compared to pre-intervention assessments, and worth further clinical application.

OBJECTIVE To analyze the pharmaceutical service process in a fracture patient complicated by fat embolism syndrome （FES） following postoperative fracture， aiming to provide a reference for clinical treatment and pharmaceutical service for similar patients. METHODS Clinical pharmacist participated in the entire treatment process of a patient with FES following postoperative fracture. Based on the patient’s clinical manifestations and test results， literature was reviewed to assist clinical physicians in formulating the therapeutic regimen of glucocorticoids. For the drug-related adverse reactions of renal function impairment and reduced platelet count that occurred during the treatment， suspicious drugs were analyzed and disposed of accordingly. RESULTS The clinical pharmacist recommended Hydrocortisone sodium succinate for injection （100 mg， q8 h， ivgtt， for about one week followed by a gradual dose reduction） for treating FES. The Vancomycin hydrochloride for injection used in this case was assessed as “very probably” associated with the adverse drug reactions of renal function impairment and thrombocytopenia. The clinical physician adopted the pharmacist’s medication recommendations， and the patient’s condition stabilized after treatment， with improvement in adverse reactions， and was discharged from the hospital. CONCLUSIONS The use of glucocorticoids in treating FES has a definite therapeutic efficacy. Clinical pharmacists should individualize the medication plan based on the patient’s pathological state and distinguish it from postoperative sepsis. Meanwhile， drug-induced adverse reactions in the kidney and blood system should be closely monitored.

BACKGROUND:Gastrodin has anti-inflammatory effects and is mainly used in clinical practice for the treatment of ischemic stroke,and its mechanism of action is still unclear. OBJECTIVE:To explore the mechanism of gastrodin intervention on inflammatory injury in ischemic stroke rats. METHODS:Fifty Sprague-Dawley rats were divided into sham-operated group,model group,positive control group,high-dose gastrodin group and low-dose gastrodin group by the randomized numerical method,with 10 rats in each group.Ischemic stroke models were established by the middle cerebral artery occlusion method in all groups of rats except for the sham operation group.Administration in each group started on the 3rd day after surgery,and the rats in the positive control group were intraperitoneally injected with edaravone injection(6 mg/kg),the rats in the high-and low-dose gastrodin groups were intraperitoneally injected with 50 and 10 mg/kg gastrodin injection respectively,and the rats in the sham-operated and model groups were intraperitoneally injected with the equal volume of physiological saline.After 14 days of continuous treatment in each group,the pathological changes in rat brain tissue were observed,and the positive expression of NLRP3 inflammasome and the expression of inflammatory response-related proteins and their mRNAs were detected. RESULTS AND CONCLUSION:Compared with the sham-operated group,the volume of cerebral infarction became larger in the model group;the structure of brain tissue was loose,irregular cavities could be observed,and the number of neurons was reduced and irregularly arranged;the positive expression of NLRP3 inflammasome increased(P<0.01);and the protein and mRNA expression levels of Toll-like receptor 4,myeloid differentiation factor 88,apoptosis-associated speck-like protein containing a caspase-recruitment domain,Caspase-1,and interleukin-1β increased(P<0.01).Compared with the model group,the volume of cerebral infarction became smaller in the high-and low-dose gastrodin groups;the neurons were regularly arranged,increased in number,and uniformly distributed;the positive expression of NLRP3 inflammasome was decreased(P<0.05);the protein and mRNA expression levels of Toll-like receptor 4,myeloid differentiation factor 88,apoptosis-associated speck-like protein containing a caspase-recruitment domain,Caspase-1,and interleukin-1β were decreased in the high-dose gastrodin group(P<0.01);Toll-like receptor 4 protein expression showed no significant changes in the low-dose gastrodin group,and the protein and mRNA expression of the other inflammatory response-associated factors decreased(P<0.05,P<0.01).To conclude,gastrodin attenuates inflammatory injury in ischemic stroke rats,and its mechanism of action may be related to the inhibition of inflammatory response-associate factor expression.

Objective:To analyze the efficacy and safety of daratumumab plus dexamethasone in the treatment of renal injury patients with light chain amyloidosis, and to provide clinical reference.Methods:It was a single center retrospective observational study. The clinical data before and after daratumumab treatment of renal injury patients with light chain amyloidosis treated with daratumumab plus dexamethasone from December 2021 to August 2022 were retrospectively collected. The hematologic response, kidney response, prognosis, and adverse events were analyzed. The treatment regimen was 16 mg/kg intravenous infusion of daratumumab on day 1 + 20 mg intravenous push of dexamethasone on day 1-2, once every 2 weeks. The follow-up was up to February 28, 2023.Results:The study included 18 patients, with age of (58.4±7.7) years old, and a male to female ratio of 11∶7. Eleven patients were newly diagnosed and 7 patients were retreated. There were 7, 5, 5 and 1 patients, respectively at the stage Ⅰ, Ⅱ, Ⅲ and Ⅳ of light chain amyloidosis according to 2012 Mayo stage criteria. The median course of disease before onset was 2.5 (1.0, 8.0) months and the follow-up time was (8.7±2.8) months. The patients received (10±3) times of treatment. The overall hematologic response rates were 9/13, 11/13 and 13/13 at 1 month, 3 months, and 6 months respectively after treatment, meanwhile 8/13, 10/13 and 12/13 achieved at least very good partial response at 1 month, 3 months, and 6 months respectively (the other 5 patients did not undergo detailed evaluation due to baseline difference of serum free κ and λ light chain <20 mg/L). The median duration of hematologic response was 16 (13, 40) days. At 3 months, 6 months and the end of follow-up, 10, 13 and 13 of 18 patients respectively achieved renal response, and the median duration of response was 66 (26, 182) days. During follow-up, the median difference of serum free κ and λ light chain decreased by 93% (72%, 97%). Until the last follow-up, one patient died of organ hemorrhage. Other infusion reactions, leukopenia, neutropenia and infection all improved after symptomatic treatments.Conclusion:Daratumumab plus dexamethasone treatment is effective for light chain amyloidosis nephropathy in inducing hematologic remission and kidney remission, with good safety.
