Objective: This study compared the effects of personalized exercise versus acupuncture on multidimensional cognitive function in individuals at high risk for stroke with mild cognitive impairment (MCI). Methods: A randomized controlled trial enrolled 200 stroke-risk adults aged 50−80 years. Ninety participants diagnosed with MCI (MMSE, HIS, CDR criteria) were randomly assigned to exercise (n = 30), acupuncture (n = 30), or control (n = 30) groups. Interventions lasted 6 months. Cognitive outcomes (MMSE, Raven’s Progressive Matrices, Digit Symbol Substitution Test, Animal Fluency, Rey-Osterrieth test, Stroop test) were assessed before and after intervention. Multivariate regression identified risk factors for MCI. ANOVA was used for group comparisons. Results: Hypertension (aOR = 1.5) and diabetes (aOR = 1.3) were significant risk factors for MCI. After intervention, the exercise group showed the largest MMSE improvement (Δ = 5.0), compared with acupuncture (Δ = 3.0) and control (Δ = 1.0) (p < 0.001). Exercise produced greater gains in non-verbal reasoning (31.8% vs. 26.1% in acupuncture, p < 0.01). Acupuncture more effectively enhanced processing speed and attention (DSST: Δ = 26 vs. Δ = 20 in exercise, p = 0.03) and executive function (Stroop interference time: Δ = 16 vs. Δ = 15 seconds in exercise, p = 0.04). Both interventions significantly improved verbal fluency (p < 0.001), with larger benefits in those with baseline MMSE ≤ 20. Conclusion Hypertension and diabetes are key risk factors for MCI in stroke-prone individuals. Exercise yields greater improvement in global cognition and memory, whereas acupuncture is more effective for enhancing attention and executive function. Both modalities benefit verbal fluency, particularly in lower-functioning participants.

Objective:To explore the application value of renin-angiotensin-aldosterone system (RAAS) indexes in the clinical diagnosis of essential hypertension.Methods:Eighty-eight patients with essential hypertension treated in the 962nd Hospital of the PLA Joint Logistics Support Force from April 2023 to May 2024 were enrolled as the observation group, and 80 normotensive healthy subjects undergoing physical examination in the same hospital during the same period were selected as the control group. RAAS-related indexes [angiotensin Ⅱ (ATⅡ), plasma renin activity (PRA), and aldosterone (ALD)] were detected in both groups. The levels of ATⅡ, PRA, ALD, and the ratio of plasma ALD to PRA (ARR) were compared between the two groups and among subgroups with different hypertension severities in the observation group. The diagnostic efficacy of each index for essential hypertension was analyzed by receiver operating characteristic (ROC) curve.Results:The levels of ALD, ATⅡ, and ARR in the observation group were significantly higher than those in the control group, while the PRA level was significantly lower (all P<0.05). Among the three subgroups in the observation group, the levels of ATⅡ, ALD, and ARR showed a significant increasing trend in grade 1, grade 2, and grade 3 hypertension subgroups, while the PRA level showed a significant decreasing trend (all P<0.05). ROC curve analysis showed that the areas under the curve (AUC) of plasma PRA, ATⅡ, ALD, and ARR for the diagnosis of essential hypertension were 0.814, 0.703, 0.687, and 0.879, respectively. The combined detection of the four indexes had an AUC of 0.918, with the highest sensitivity and accuracy. Conclusions:Changes in RAAS indexes are closely related to the occurrence and severity of essential hypertension. PRA and ARR are effective indexes for the diagnosis of essential hypertension. The combined detection of the four indexes can achieve more ideal diagnostic efficacy and improve the diagnostic satisfaction of patients.

Objective:To investigate the clinical efficacy and safety of ultrasonic bone scalpel in nasal osteotomy.Methods:A retrospective analysis was conducted on clinical data from the patients who received ultrasonic bone scalpel-assisted nasal osteotomy in the Nasal Plastic & Reconstructive Surgery Department, Plastic Surgery Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College between January 2023 and April 2024. All patients underwent open lateral approach osteotomy using an ultrasonic bone scalpel under direct vision, combined with augmentation rhinoplasty using autologous costal cartilage grafting. Intraoperatively, the nasal dorsum was fully exposed, and the lateral nasal cartilage was separated from the nasal septum, followed by precise bone tissue incision using the ultrasonic bone scalpel. Parameters recorded included operative time, and postoperative complications. Based on the standardized photographs taken before the operation and during the 6-month follow-up after the operation, the observer global aesthetic improvement scale (GAIS) was evaluated by a third-party doctor, with a score ranging from 1 to 5. The smaller the score, the more significant the improvement compared to before the operation. The satisfaction of patients with the surgical outcome was evaluated and classified into four levels: very satisfied, satisfied, dissatisfied, and very dissatisfied.Results:A total of 25 female patients were enrolled, aged 20 to 38 years, with an average age of 27.1 years. All procedures were completed successfully, with a mean operative time of (25.4±4.2) minutes. Postoperative localized swelling of varying degrees was observed. Follow-up ranged from 6 to 18 months, with nasal contour and curvature stabilizing by 6 months postoperatively. No complications, such as infection, nasolacrimal duct, lacrimal sac, medial canthal ligament, nerve injuries, or sensory disturbances, were reported. Two cases exhibited mild nasal bone widening at the 6-month follow-up, though no surgical revision was requested. Significant improvement in external nasal morphology was achieved in all patients, with high satisfaction rates. The patients satisfaction survey showed that 18 cases (72%) were very satisfied and 7 cases (28%) were satisfied with the surgical outcome. GAIS scores reflected positive evaluations [(1.24±0.51) points].Conclusion:The ultrasonic bone scalpel for nasal osteotomy offers the advantages of high-precision cutting and efficient hemostasis. It is highly effective in reshaping the nasal contour, with shorter osteotomy time, reduced intraoperative bleeding, and a lower postoperative complication rate. This study provides some insights into plastic surgeons in optimizing nasal bone modification strategies.

Objective To investigate correlations of the ratio of specific brain region volume to total brain volume(ratio％),standard uptake value(SUV)of specific brain region based on 18F-FDG PET/MR examination in Alzheimer disease(AD)patients,as well as the relationship between changes of these two.Methods Fifty AD patients were retrospectively collected.Based on FDG PET/MR,the ratio％and the mean SUV(SUVmean)of 40 specific brain regions were obtained,and the correlation between ratio％and SUVmean for each region were evaluated.According to a database of normal brains,Z-scores for ratio％and SUVmean were calculated to represent structural and functional changes in AD patients,and the correlation between these 2 Z-scores was assessed.Results Correlations were found between ratio％and SUVmean,also between Z-scores of these two parameters in 29 brain regions(r=0.288 to 0.778,all P＜0.05).Among them 7 brain regions,i.e.bilateral middle temporal gyrus,right fusiform gyrus,right hippocampus,right precuneus,left lingual gyrus and right parahippocampal gyrus exhibited correlation coefficients greater than 0.6.Conclusion There were some relationships between brain structural and metabolic functions and their changes in AD patients showed on FDG PET/MR.

There is significant inter-individual variation of pharmacokinetics and pharmacody-namics in patients receiving tacrolimus(TAC)for an-ti-rejection therapy,which cause the rejection or toxic action.Based on results of therapeutic drug monitoring and pathophysiological index of trans-plant patients,the individualized dosing regimen can be designed and adjusted by using model in-formed precision dosing(MIPD).The patients'clini-cal outcome can be improved.In the consensus,the different methods of MIPD used for patients re-ceived TAC for anti-rejection therapy were intro-duced,which can be used for the designing and ad-justing doing regimen,predicting adverse drug reac-tion,improving medication adherence and econom-ics during therapy.

AIM:To explore the causal association between the counts of five types of white blood cells—neutrophils,monocytes,eosinophils,baso-phils,and lymphocytes—and venous thromboem-bolism(VTE).METHODS:Mendelian randomization(MR)analysis method was used,with genetic vari-ants associated with the five types of white blood cells as instrumental variables,and venous throm-boembolism occurrence risk as the outcome vari-able,inverse variance-weighted(IVW)method was employed as the primary analysis method,with MR-Egger regression,weighted median(WM),sim-ple model,and weighted mode methods used as supplements,to analyze the causal association be-tween the counts of five types of white blood cells and VTE,followed by reverse MR analysis.RE-SULTS:Neutrophil and lymphocyte counts are caus-ally associated with the risk of VTE.For neutrophil count,the IVW estimate(OR=0.867,95%CI:0.761-0.981,P=0.031),MR-Egger estimate(OR=0.754,95%CI:0.571-0.996,P=0.048),weighted median es-timate(OR=0.846,95%CI:0.729-0.981,P=0.027),and weighted model estimate(OR=0.748,95%CI:0.595-0.942,P=0.014)were calculated.For lympho-cyte count,the IVW estimate(OR=0.838,95%CI:0.741-0.949,P=0.005)and weighted median esti-mate(OR=0.024,95%CI:0.718-0.977,P=0.024)were calculated.Reverse MR analysis showed a causal association between the risk of VTE and neu-trophil count,the IVW estimate(OR=0.989,95%CI:0.980-0.999,P=0.024).CONCLUSION:Neutrophil and lymphocyte counts are related to the risk of VTE,and decrease in neutrophil and lymphocyte numbers may increase the risk of VTE.VTE occur-rence risk is associated with neutrophil count,and reducing the risk of VTE occurrence may increase neutrophil count.Further research is needed to un-derstand the underlying biological mechanisms be-hind this relationship.

Purpose To investigate the correlation between molecular typing of urothelial carcinoma(UC)and its clinicopathologic features and prognosis,in order to explore the prognostic markers and therapeutic targets for UC.Methods 115 patients with UC were retrospectively analyzed.Immunohistochemical markers GATA-3,CK20,CK5/6 and CD44 were used for molecular typing of UC(luminal-like type,basal-like type and null).Correlations between molecular typing and clinicopathological features were analyzed using the Chi-square test and Fisher precise test.Sur-vival analysis was performed using the Kaplan-Meier test and Log-rank test.Results The expression of GATA-3 and CK20 was negatively correlated with the clinical stage of UC,while the expression of CD44 was positively correlated with the clinical stage of UC(both P＜0.05).CK20 was a marker of good prognosis(P=0.03).The proportion of clinically advanced UC with basal-like type was significantly higher than that of luminal-like type(78.4％vs 53.4％,P=0.033).Among the histologic variants,UC with neuroendocrine differentiation(100％),sarcomatoid carcinoma(80.0％)and squamous differentiation(77.8％)were basal-like type.All plasmacytoid and lymphoepithelioma-like types,as well as 81.8％of micropapillary UC.Among the null phenotypes,the differential variant predominated(66.7％).Compared with the luminal-like type,although the prognosis of basal-like UC was worse,there was no sta-tistically significant difference(P＞0.05).Conclusion Patients with CK20-expressing UC had a significantly better prognosis.The main histologic variants types of basal-like type and coelomofacial type are different.Molecular typing of UC using immunohistochemical markers is suggestive of clinical staging and prognosis of patients.
