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.

Background Previous studies found that high temperature and heatwave increase the risk of traffic injuries. The complex road conditions in Yunnan Province result in frequent traffic accidents. However, there is limited evidence on the correlation between heatwave and traffic injuries in Yunnan Province. Objective To assess the association between heatwave events and traffic injuries, to estimate its disease burden, and to identify relevant sensitive groups. Methods We collected data on traffic injury cases and concurrent meteorological information from four surveillance sites in Yunnan Province, China: Dali, Lufeng, Zhaoyang, and Qilin from May to September each year from 2015 to 2023. Traffic injury cases refer to patients who visited the outpatient or emergency departments of local surveillance hospitals for the first time due to traffic injuries. Meteorological data were derived from the fifth generation atmosphericreanalysis dataset of the global climate provided by the European Centre for Medium-Range Weather Forecasts. A time-stratified case-crossover design combined with distributed lag non-linear model was used to analyze the association between short-term exposure to heatwave and traffic injuries. We also conducted subgroup analyses by sex, age, occupation, injury cause, activity at the time of injury occurrence, and severity of injury. Results A total of 34764 traffic injury surveillance cases were included in the analysis. The risk of traffic injuries occurred during heatwave was 1.13 times (95%CI: 1.07, 1.20) greater than those occurred during non-heatwave, and 2.64% (95%CI: 1.49%, 3.73%) of traffic injuries were attributed to heatwave exposure throughout the study period. The results of stratified analysis showed greater impacts of heatwave on the risk of traffic injuries in female [odds ratio (OR)=1.17, attributable fraction (AF)=3.23%], people aged 15-64 years (OR=1.13, AF=2.68%), farmers/workers (OR=1.22, AF=4.07%), people with non-motor vehicle traffic injuries (OR=1.17, AF=3.24%), people who were driving or riding when injuries occurred (OR=1.12, AF=2.43%), and people with minor injuries (OR=1.18, AF=3.49%) ( P<0.05). Longer duration [excess risk (ER)=0.99%] and greater intensity (ER=4.12%) of heatwave had greater impacts on the risk of traffic injuries (P<0.05). Conclusion Heatwave events are associated with an increased risk of traffic injuries. Female, people aged 15-64, farmers/workers, people with non-motor vehicle traffic injuries, those injured while driving/riding a vehicle, and people with minor injuries are particularly vulnerable. The findings suggest that targeted mitigation and adaptation measures should be taken to address the risk of traffic injuries associated with extreme climate events.

Objective To study the dynamic changes in the secretion of neurotransmitters glutamic acid(Glu)and γ-aminobutyric acid(GABA)in the central auditory brain area,in order to explore the effects of sodium salicy-late on different locations of the auditory pathway.Methods A total of 126 SD rats were injected intraperitoneally with salicylate,and were divided into 10 groups including injection groups for 1,2,4,8,and 24 hours,chronic in-jection groups for 3,7,and 14 days,and chronic recovery groups for 21 and 28 days with 6 rats in each group,as well as their corresponding blank control groups.Rats in each group were anesthetized and materials were collected for further use.High-performance liquid chromatography(HPLC)was performed to detect and compare the dynam-ic changes in the levels of Glu and GABA in the auditory cortex,inferior colliculus,cochlear nucleus,and hippocam-pus of the auditory center of rats in each group at different time points.Results Compared with the control group,within 24 hours of acute injection of salicylate,the Glu content in the auditory cortex reached the peak in 1 hour,and the hippocampus reached the peak at the 4th hour after injection,and then decreased slowly.The GABA con-tent in the four brain regions showed a slow upward trend in the chronic injection period,reached the peak on the 7th day,decreased and approached normal level on the 14th day,and basically returned to the normal level in the re-covery period.Conclusion These findings indicate that salicylate has a certain short-term excitatory and stimulating effect on the central auditory system.Under the mechanism of central plasticity,after long-term injection of salicy-late,the release of neurotransmitters reaches a new excitation/inhibition balance in the central area.Glu and GABA may each play a different role that may ultimately lead to the development of tinnitus.

A 76-year-old female patient took soaking water of Tetrastigma hemsleyanum 15 g daily by herself after lung cancer resection and chemotherapy. After 3 months of medication, the patient developed fatigue and dry mouth. After 4 months of medication, decrease of white blood cells and hemoglobin and increase of fasting blood glucose and glycosylated hemoglobin appeared and were gradually aggravated. After 6 months of medication, the white blood cell count was 2.8×10 9/L, hemoglobin was 88 g/L, red blood cell count was 3.05×10 12/L, fasting blood glucose was 10.01 mmol/L, and glycosylated hemoglobin was 6.93%. Diabetes mellitus, leukopenia, and anemia were diagnosed, which were considered to be related to Tetrastigma hemsleyanum. The patient was asked to stop drinking the soaking water of Tetrastigma hemsleyanum and the traditional Chinese medicine decoction was given. Two months later, the patient′s blood cells returned to normal, fasting blood glucose was 6.08 mmol/L, and glycosylated hemoglobin was 6.10%. The prescribed daily dose of Tetrastigma hemsleyanum in Chinese Medicine Record is 3-9 g. Diabetes mellitus and hemocytopenia in the patient might be related to overdose and long-time use of the drug.

Objective To observe the effects of rehabilitation intervention on the quality of life (QOL) of patients after coronary artery bypass grafting. Methods Fifty-eight hospital patients in need of coronary artery by-pass grafting (CABG) were randomly assigned to a cardiac rehabilitation group ( rehab ; n = 31 ) or a routine care group (control; n = 27 ). In the rehab group, patients received progressively increasing movement and appropriate psychological intervention. Changes in the medical outcome study short form (SF-36) scores and 6 min walk dis-tances (6MWDs)as well as the length of post-operative stays in hospital were observed in both groups. Results Compared with the control group, patients in the rehab group scored significantly higher on the SF-36. Their physical functioning, general health, vitality, role-emotion and mental health scores improved significantly, their final 6MWDs were longer, and they had significantly shorter average hospital stays after the operation. Conclusions Rehabilita-tion training can improve QOL for patients after coronary artery bypass grafting.

Objective To observe the effects of rehabilitation on the quality of life and capacity of aerobic exercise in patients after coronary artery bypass graft. Methods 58 patients after coronary artery bypass graft were divided into rehabilitation group (n=31) and control group (n=27). Patients in the control group received routine drug treatment out of hospital, while the rehabilitation group was guided regularly for rehabilitation. All patients were surveyed with the MOS item short form health survey (SF-36) and 6 min walking test on the 15th and the 90th day after operation. Results Compared with the control group，the scores of all the items of SF-36 in rehabilitation group improved (P<0.01) except in body pain. The result of 6MWT was also higher in rehabilitation group than in controls(P<0.01). Conclusion Rehabilitation can improve capacity of aerobic exercise and the quality of life of patients after coronary artery bypass grafting.

Objective To investigate whether iron mass induces HO-1 overexpression and explore the role of HO-1 in rat intracerebral hemorrhage(ICH). Methods In this study,144 hydrated chloride aldehyde-anesthetized Sprague- Dawley rats were used,autologous blood were injected into the right caudate nucleus to establish the ICH model.Saline injection and health were served as controls.Deferoxamine(DFO)with an intraperitoneal injection served as intervention group.Enhanced Perl's reaction was used for iron staining and brain iron deposits were determined.Brain HO-1 level were examined by immunohistochemical analysis and reverse transcription polymerase chain reaction(RT-PCR). Results There was a 21-fold increase in iron deposits around the hematoma 7 days after the infusion of 100 μl of autologous blood.Markedly increased levels of perihematomal HO-1 immunoreactivity and HO-1 mRNA in all ICH rats were detected at 3-14 days.The addition of DFO significantly reduced iron deposits in the ipsilateral basal ganglia at 7-14 days after ICH.DFO also inhibited HO-1 overexpression at day 7,14.Correlations test showed that there were positive correlations of iron sediments with HO-1mRNA(r=0.647)and HO-1 immunopositive cells(r=0.209). Conclusions ICH causes iron accumulation in the brain.Iron overloading may induce HO-1 upregulation after ICH.Ratherly,the HO-1 moderate increasing possibly fits with the events,whereas HO-1 overexpression may result in its dysfunction.It may be prudent to intervene ICH with HO-1 inhibitor.
