ObjectiveTo avoid stress responses in experimental monkeys caused by direct capture, and to improve the adaptability and experimental efficiency of marmosets in behavioral, two-photon imaging, and electrophysiological experiments, a device for immobilizing marmosets without the need for capture is developed. MethodsA set of compatible transport cage and monkey chair was produced through 3D graphic design and printing. First, the transport cage was aligned with the feeding outlet of the experimental housing cage, and the marmoset was gently guided into the transport cage. Then, the transport cage was connected to the monkey chair, and the marmoset was gently guided into the chair for immobilization. Subsequent experiments were carried out afterward. The effectiveness was evaluated by observing the efficiency of transport and immobilization, the marmoset cooperation level, and stress responses. ResultsAfter testing and improvements, the device successfully completed immobilization of marmosets without the need for capture, significantly improving the fluency and efficiency of the experiment. As the number of operations increased, the marmosets became more cooperative, and the operation speed was significantly enhanced. After using the device, the stress responses were noticeably reduced, with marmosets showing lower stress levels. In particular, compared to traditional capture methods, the use of this device significantly reduced marmoset anxiety and discomfort, increasing their cooperation levels during the experiment. ConclusionThe monkey chair device designed allows for restraint of marmosets without the need for capture, ensuring smooth progress of subsequent experiments while also safeguarding animal welfare. This device is easy to operate, highly practical, cost-effective, and has great potential for widespread application.

Objective To explore the association of the magnitude of systolic blood pressure reduction(SBPr)with post-procedure 24 h symptomatic intracranial hemorrhage(sICH)and 90-day clinical outcomes in patients with successful endovascular thrombectomy(EVT).Methods Consecutively registered patients with EVT caused by anterior circulation large vessel occlusion stroke(LVOS)in the First Affiliated Hospital of Wannan Medical College(Yijishan Hospital)between July 2015 and April 2023 and patients with successful reperfusion were analyzed.Demographic data,medical history(hypertension,diabetes),the trial of Org 10172 in acute stroke treatment(TOAST)classification,the baseline National Institutes of Health Stroke Scale(NIHSS)score and the baseline Alberta stroke early CT(ASPECT)score of patients were collected.And procedure related parameters(including time from onset to puncture,time from onset to reperfusion,occluded site[internal carotid artery,M1 segment of middle cerebral artery,M2 segment of middle cerebral artery],collateral circulation status[determined based on preoperative occluded angiography showing the range of collateral circulation in the occluded vessel area,defined as good collateral circulation with a reflux range of ≥ 50%and poor collateral circulation with a reflux range of<50%]),immediate postoperative reperfusion status(evaluated using the modified thrombolysis for cerebral infarction[mTICI]grading,successful reperfusion defined as mTICI grading of 2b-3),24 hours sICH,and 90 days clinical outcomes(evaluated using the modified Rankin scale score at 90days after EVT,with a score ≤ 2indicating a good prognosis and a score>2indicating a poor prognosis).SBPr was defined as(baseline SBP-mean SBP)/baseline SBP x 100%.According to the the magnitude of SBPr,SBPr is divided into 5 categories(<-10%,-10%-10%,>10%-20%,>20%-30%and>30%).Based on the clinical outcomes at 90 days and the occurrence of sICH at 24 hours after EVT,patients were divided into a good prognosis group and a poor prognosis group,as well as an sICH group and a non-sICH group.The relationship between SBPr and postoperative 90 days clinical prognosis or sICH was analyzed using a binary Logistic regression model.Subgroup analysis was conducted based on a history of hypertension(yes and no),continuous intravenous hypotensive therapy(yes and no),baseline ASPECT scores(3-5 and 6-10),and collateral circulation status(good and bad).Using a restricted cubic plot to depict the relationship between SBPr and sICH and clinical prognosis at 90days.Results(1)In total,731 patients were included.The median age was 71(62,77)years and 424(58.0%)were men.The median baseline NIHSS score was 14(12,18),the median baseline ASPECT was 9(7,10),405(55.4%)patients achieved 90-day modified Rankin scale score 0-2,and 35 patients(4.8%)developed sICH.(2)Multivariate analysis showed that the older age(OR,1.036,95%CI 1.017-1.056),the higher baseline NIHSS score(OR,1.095,95%CI1.049-1.144),the lower baseline ASPECT score(OR,0.704,95%CI 0.636-0.780),diabetes(OR,1.729,95%CI 1.084-2.758),bad collateral circulation(good collateral circulation vs.bad collateral circulation,OR,0.481,95%CI 0.332-0.696)and SBPr>30%(SBPr-10%-10%as a reference,OR,2.238,95%CI 1.230-4.071),the higher the risk of poor clinical outcomes at 90 days(all P<0.05).Continuous intravenous hypotensive therapy is a risk factor for postoperative 24 h sICH(OR,2.278,95%CI 1.047-4.953;P=0.038),while SBPr 20%-30%is associated with a lower risk of postoperative 24 h sICH(SBPr-10%-10%as a reference,OR,0.362,95%CI0.131-0.998;P=0.049).(3)The restrictive cube plot shows that there is a U-shaped relationship between SBPr after EVT and poor clinical outcomes at 90 days,while there is a nearly linear relationship with the occurrence of sICH.The more SBP reduction,the lower the incidence of sICH.(4)In the subgroup analyses,in the non-hypertension history and the good collateral circulation group,SBPr>30%has a higher risk of poor clinical outcomes compared to SBPr-10%-10%(OR and 95%CI were 2.921[1.000-8.528]and 2.363[1.078-5.183],respectively,with P=0.05 or P<0.05);After EVT,the group receiving continuous intravenous hypotensive therapy and the baseline ASPECT score 6-10 groups showed a significant correlation between SBPr>30%and poor clinical outcomes at 90 days(SBPr-10%-10%as a reference,OR and 95%CI were 2.646[1.168-5.993]and 2.481[1.360-4.527],respectively,with P<0.05).The correlation between SBPr and lower incidence of sICH was only found in the subgroup of poor collateral circulation(SBPr-10%-10%as a reference,SBPr>20%-30%:OR,0.133,95%CI 0.027-0.652;SBPr>30%:OR,0.104,95%CI 0.013-0.864;all P<0.05).Conclusions Among patients who achieved successful reperfusion with EVT,SBPr might be related to a worse functional outcome at 90 days and sICH 24 h after operation.However,the relationship may exhibit significant heterogeneity across different subgroups.Baseline ASPECT score,history of hypertension,collateral circulation,and the use of continuous venous hypertension after EVT have been highlighted in individualized blood pressure management after EVT.

Objective:To put forward a self-created aesthetic concept of " Five narrow and one low" and to evaluate the clinical effect of contouring the upper arm and its surrounding area under this concept.Methods:From January 2020 to January 2023, 55 female patients, aged 20 to 50 (mean age 33.0±6.4) years, had their upper arms and surrounding area contours shaped according to the concept of " five narrow and one low" in Changsha My Like Medical Cosmetology Hospital. Liposuction was performed in the upper arm, scapular area, accessory breast area, and armpit area under local swelling combined with sedation and anesthesia. After liposuction in the medial upper arm, bipolar radiofrequency Body Tite compression was performed. Multiple botulinum toxin injections were performed postoperatively in the bilateral traperius muscles. The maximum circumference and sag distance of upper arm of both sides before and after surgery were measured. Patients′ satisfaction was assessed by satisfaction questionnaire.Results:The patients were followed up for 1-6 months after operation, and the liposuction (minimum-maximum) of 55 cases was (1 200±383) ml. The maximum circumference of the left upper arm was (32.85±4.98) cm before surgery and (27.03±3.13) cm after surgery. The maximum circumference of the left upper arm was reduced by (18.65±2.79) %. The maximum circumferential diameter of the right upper arm was (33.3±5.3) cm before surgery and (27.23±3.30) cm after surgery. The maximum circumferential diameter of the right upper arm was reduced by (18.42±2.84) %. The maximum sag distance of the upper arm was (7.12±2.08) cm before surgery and (4.04±1.22) cm after surgery. The maximum sag distance of the upper arm was reduced by (43.22±4.08) %. All the follow-up patients believed that the aesthetic effect of " five narrow and one low" was achieved, the satisfaction score was 4.62±0.51, and no serious complications occurred.Conclusions:The application of the aesthetic concept of " Five narrow and on low" in the contour shaping of the upper arm and the surrounding aera can achieve a better uniform, smooth and smooth surgical effect.

Objective To investigate the influencing factors for acute multiple vessels occlusion(MVO)and its impact on the prognosis of patients with anterior circulation acute large vessel occlusion stroke(ALVOS)who achieved successful recanalization after endovascular treatment(EVT).Methods Patients with anterior circulation ALVOS who received successful EVT at the Yijishan Hospital of Wannan Medical College between July 2015 and April 2023 were retrospectively analyzed.Baseline data,including age,sex,onset-to-puncture time(OTP),onset-to-recanalization time(OTR),medical history(including atrial fibrillation,diabetes,hypertension),alcohol and smoking history,admission blood pressure(systolic and diastolic),Alberta stroke program early CT score(ASPECTS),National Institutes of Health stroke scale(NIHSS)score,trial of Org 10172 in acute stroke treatment(TOAST)classification(atherosclerotic type,cardioembolic type,and other etiology types),and 90-day modified Rankin scale(mRS)score were collected.Collateral circulation was assessed based on the degree of contrast agent reflux observed in the occluded arterial supply area during delayed DSA,and patients were classified into poor and good collateral circulation groups.Malignant cerebral edema was defined as a midline shift of ≥5 mm on the follow-up CT scan performed on day 3 post-surgery.The primary endpoint(efficacy indicator)was the 90-day mRS score,with mRS score≤ 2 considered as a good prognosis and mRS score>2 considered as a poor prognosis.The secondary endpoint(safety indicator)was the 90-day mortality rate.All patients were divided into MVO and non-MVO groups based on whether they had single or multiple intracranial vessel occlusions.Acute MVO was defined as the detection of acute occlusion of other large or medium vessels,in addition to the main vessels(internal carotid artery or M1/M2 segments of the middle crebral artery[MCA]),in CT angiography,MR angiography,or DSA,resulting in ischemia in brain regions distinct from the main occlusion area.Factors that showed statistically significant differences in univariate analysis were further analyzed using multivariate Logistic regression to identify the risk factors for the occurrence of acute MVO and the factors associated with the prognosis of ALVOS patients.Results A total of 846 patients with ALVOS were included,with ages ranging from 26 to 94 years(mean age[69±11]years).The proportion of male patients was 57.2%(484/846).The median admission ASPECTS was 8(7,9)and the median admission NIHSS score was 14(12,18).The incidence of malignant cerebral edema at 3 days post-surgery was 13.4%(112/835),and the 90-day mortality rate was 19.1%(162/846).(1)Among the 846 ALVOS patients,810(95.7%)were in the non-MVO group and 36(4.3%)were in the MVO group.Univariate analysis showed significant differences between the MVO and non-MVO groups in terms of atrial fibrillation,malignant cerebral edema,admission ASPECTS,admission NIHSS scores,TOAST classification,collateral circulation,rate of complete recanalization,and 90-day poor prognosis rate(all P<0.05).However,there was no statistically significant difference in 90-day mortality between the two groups(P=0.193).Multivariate Logistic regression analysis showed that TOAST classification of cardioembolic type(OR,16.089,95%CI 1.835-141.061,P=0.012)and other etiology types(OR,9.768,95%CI 1.078-88.540,P=0.043)were associated with the occurrence of MVO.(2)Among the 846 ALVOS patients,445 had a good prognosis at 90days,and 401 had a poor prognosis.Univariate analysis showed that,compared to the good prognosis group,the poor prognosis group had a lower proportion of males and smokers,and a higher proportion of patients with older age,higher baseline systolic blood pressure,hypertension,diabetes,and atrial fibrillation(all P<0.01).Additionally,the poor prognosis group had higher admission NIHSS scores(P<0.01),lower admission ASPECTS,lower rates of good collateral circulation and complete recanalization,higher rates of malignant cerebral edema and MVO,and statistically significant differences in TOAST classification distribution(all P<0.01).Multivariate Logistic regression analysis showed that MVO was associated with poor 90-day prognosis in ALVOS patients after EVT(OR,3.368,95%CI 1.149-9.878,P=0.027).Furthermore,older age(OR,1.045,95%CI 1.025-1.066),diabetes(OR,1.719,95%CI 1.080-2.734),higher baseline systolic blood pressure(OR,1.012,95%CI 1.004-1.019),lower admission ASPECTS(OR,0.746,95%CI 0.674-0.826),higher admission NIHSS score(OR,1.115,95%CI 1.070-1.162),without immediate postoperative complete recanalization(OR,0.413,95%CI 0.290-0.592),poor collateral circulation(OR,0.594,95%CI 0.415-0.851),and malignant cerebral edema(OR,6.191,95%CI 3.026-12.670)were all associated with poor 90-day prognosis after EVT in ALVOS patients(all P<0.05).Conclusions The TOAST classification of cardioembolic type and other etiology types is associated with MVO.MVO is a risk factor for poor outcomes after successful EVT in ALVOS patients.

Objective To investigate the composition of symptom clusters in early postoperative breast cancer patients and analyze the sentinel symptoms of each cluster of symptoms. Methods A total of 309 patients who underwent mastectomy were conveniently sampled and surveyed using the Chinese version of the Anderson Symptom Inventory. Principal component analysis and varimax orthogonal rotation were employed to analyze the symptom clusters, and their associations were analyzed using the Apriori algorithm model to identify the sentinel symptoms of each cluster of symptoms. Results Three symptom clusters were identified in early postoperative breast cancer patients: neuro-sleep symptom cluster [fatigue (weakness)-distress-pain-sleepiness-restless sleep], sensory-perception symptom cluster (numbness-forgetfulness-shortness of breath-sadness-dry mouth), and digestive system symptom cluster (nausea-vomiting-loss of appetite). Fatigue was the sentinel symptom of the neuro-sleep symptom cluster, numbness was the sentinel symptom of the sensory-perception symptom cluster, and nausea was the sentinel symptom of the digestive system symptom cluster. Conclusion Early postoperative breast cancer patients experience multiple symptom clusters, with sentinel symptoms existing in each cluster. Healthcare staff should develop intervention measures based on sentinel symptoms to improve the efficiency of symptom management and reduce the degree of symptom distress for patients.
