Magnetic Resonance Imaging(MRI)technology can directly show the changes of brain network and explain the central mechanism of Tai Chi remodeling of brain structure and function.In this paper,we collected the domestic and foreign research on the influence of Tai Chi movement on the brain network by using MRI technology,and combed it from the perspective of brain structure and function changes.The results revealed that Tai Chi may promote memory function,cognitive flexibility,inhibitory control,and working memory capacity by remodeling the structure and function of the medial temporal lobe and prefrontal cortex in older adults,which may be a potential central mechanism for Tai Chi to improve memory and cognitive control in the elderly.However,there are some problems in the current research,such as small sample size,insufficient long-term follow-up,and difficult evaluation of exercise intensity.It is necessary to carry out large-sample and long-term detailed research to further verify the current research results.

Objective:To evaluate the safety and efficacy of ciprofol and propofol for gynecological surgeries with general anesthesia through a meta-analysis.Methods:Electronic databases including PubMed, Embase, Cochrane, Web of Science, China National Knowledge Infrastructure, Wanfang Data, China Biomedical Literature Database, and China Science and Technology Journal Database were searched for randomized controlled trials comparing the safety and efficacy of ciprofol and propofol in gynecological surgeries with general anesthesia from inception to May 2023. Meta-analysis was performed using Revman 5.4 software.Results:Six randomized controlled trials were included, involving 741 patients, of which 371 received ciprofol and 370 received propofol. Compared with propofol group, the emergence time was significantly prolonged, the difference in mean arterial blood pressure, systolic blood pressure and diastolic blood pressure before and after anesthesia induction was decreased, and the incidence of injection pain, respiratory depression, body movement and hypotension was decreased in ciprofol group ( P<0.05). There were no significant differences between the two groups in terms of time of successful anesthesia induction, difference in BIS values and heart rate before and after anesthesia induction, and incidence of tachycardia, bradycardia and hypertension ( P>0.05). Conclusions:Ciprofol is comparable to propofol in terms of efficacy and has better safety than propofol when used in gynecologic surgeries with general anesthesia.

Objective:To investigate the prognostic factors associated with unresectable (stage Ⅲa-Ⅳ, according to the 7th edition of the AJCC cancer staging manual) lung squamous cell carcinoma.Methods:We retrospectively analyzed 350 patients with inoperable locally advanced, recurrent or metastatic lung squamous cell carcinoma who were admitted to the First Affiliated Hospital of Chinese Medical University from January 2005 to June 2018. The clinical pathological data, treatment and survival follow-up information of the patients were collected. Kaplan-Meier survival was used to compare the overall survival rate of different risk groups. Univariate analysis and multivariate Cox regression analysis were used to determine the independent prognostic factors.Results:A total of 350 patients were enrolled. The median overall survival (OS) of these patients was 16.7 months. Univariate analysis showed the stage, Eastern Cooperative Oncology Group(ECOG), first-line chemotherapy evaluation (RECIST version 1.1), radiation therapy, number of systemic chemotherapy lines, carcinoembryonic antigen (CEA), cancer antigen 125 (CA125), C reactive protein (CRP), lactate dehydrogenase (LDH), whether liver, brain, boneor metastasis were associated with the OS of patients with advanced lung squamous cell carcinoma (all P<0.05). Multivariate analysis showed that ECOG score ( HR=1.855, 95% CI: 1.063-3.239, P=0.030), whether underwent lung resection ( HR=0.476, 95% CI: 0.302-0.751, P=0.001), first-line chemotherapy evaluation [stable disease (SD): HR=0.293, 95% CI: 0.159-0.540, P<0.001; complete response (CR)+ partial response (PR): HR=0.223, 95% CI: 0.120-0.413, P<0.001], CRP ( HR=1.715, 95% CI: 1.080-2.723, P=0.042), LDH ( HR=1.116, 95% CI: 0.780-1.596, P=0.002) and CEA ( HR=1.855, 95% CI: 1.361-2.528, P<0.001) before chemotherapy, liver metastasis ( HR=2.453, 95% CI: 1.461-4.120, P=0.001) are independent prognostic factors for patients with unresectable lung squamous cell carcinoma. Conclusion:The ECOG score, surgical treatment history, first-line chemotherapy, LDH, CEA and CRP before chemotherapy, liver metastasis are independent prognostic factors for patients with advanced lung squamous cell carcinoma.

Objective:To explore the relationship between their proficiency, needle penetration angle and the success rate of puncture by using a self-developed venipuncture angle monitor based on remote sensing technology, and measured the needle penetration angle of people with different venipuncture proficiency levels.Methods:A total of 30 sophomore medical school undergraduates without venipuncture experience and 30 nurses with more than 3 years of clinical experience each were recruited. Volunteers performed punctures on a rubber puncture model of the arm. The result of each puncture, the volunteer′s estimated insertion angle, and the actual insertion angle measured by the monitor were recorded and analyzed.Results:The puncture success rate of the nurse group was 96.7% (58/60), and the puncture success rate of the student group was 51.7% (31/60). The puncture success rate of the nurse group was higher than that of the student group( χ2 value was 29.4, P<0.05); The estimated difference of the average angle of the nurse group was (5.2 ± 1.9) °, and the estimated difference of the average angle of the student group was (8.9 ± 2.6) °. The estimated difference of the nurse group was less than the student group ( Z value was -7.10, P<0.05); the most suitable venipuncture angle range for beginners was (31.6 ± 6.4)°. Conclusions:There is a correlation between the success rate of venipuncture and the puncture angle, and optimum puncture angle for beginners in the controlled model was (31.6±6.4)°. At both skill levels, operator estimates of the puncture angle were commonly larger than the actual angle. The angle monitor based on remote sensing technology makes the precise study of venipuncture possible.

Objective: To investigate the effect of nicorandil on ventricular arrhythmia in patients with acute ST-segment elevation myocardial infarction (STEMI) treated with emergent percutaneous coronary intervention (PCI). Methods: A total of 120 acute STEMI patients treated with emergent PCI in our hospital from January 2015 to June 2016 were randomly divided into control group and experiment group (n=60 each). Patients in both groups received conventional therapy.Patients in experiment group took 10 mg nicorandil orally before PCI and received oral nicorandil treatment (15 mg/d, three times daily) for 3 days.QT disperse(QTd), correct QTd(QTcd) and the occurrence rate of ventricular arrhythmia were compared between two groups. Results: QTd at 6, 24, 48 and 72 hours((70.6±4.4), (67.2±5.3), (55.7±8.5), (48.2±8.2) ms, respectively) after PCI was significantly lower in the experiment group than those of control group ((77.1±7.1), (71.3±6.5), (65.1±8.1), (57.2±5.4) ms, all P<0.05). The level of QTd was also significantly lower in the experiment group at 6, 24, 48 and 72 hours((77.5±7.7), (67.7±8.6), (61.2±7.5), (52.9±8.4) ms, respectively) after PCI comared to those of control group ((88.6±8.1), (79.2±7.8), (74.4±7.4), (69.6±8.6) ms, all P<0.05). There was no significant difference in the incidence of reperfusion arrhythmia during PCI procedure between the two groups.The prevalence of the ventricular premature beat in the experiment group (25/60, 41.7%) was significantly lower than in the control group(45/60, 75.0%) within 3 days after PCI(P<0.01), the prevalence of the no sustained ventricular tachycardia and ventricular fibrillation in the experiment group(6/60, 10.0%) was also significantly lower than in the control group (18/60, 30.0%, P<0.01) within 3 days after PCI. Conclusions Nicorandil use prior and post PCI could decrease the occurrence rate of ventricular arrhythmia in STEMI patients undergoing emergent PCI, and this effect might be related with reduced QTd and QTcd post medication.

Objective To investigate the effect of Probucol combined with Enalapril-folic acid tablets on endothelial function in elderly patients with H-type hypertension.Methods A total of 180 elderly patients with H type hypertension were randomly divided into three groups (n =60,each):Group A (conventional treatment),Group B (conventional treatment + a tablet containing 10 mg enalapril and 0.8 mg Folic acid/day) and Group C (conventional treatment + 500 mg Protocol twice daily + a tablet containing 10 mg Enalapril and 0.8 mg folic acid/day).Plasma hemocyanin (Hcy) and asymmetric dimethylarginine (ADMA) levels and serum nitric oxide (NO) and endothelial NO synthase (eNOS) levels were measured before treatment,and 1 and 6 months after treatment.Results In Group A,plasma Hcy and ADMA levels and serum NO and eNOS levels had no significant differences before treatment versus 1 and 6 months after treatment (P＞0.05).Plasma Hcy and ADMA levels decreased and serum NO and eNOS levels increased in Group B 6 months after treatment,compared with those at pretreatment or 1 month after treatment,which were either lower or higher than those in Group A 6 months after treatment (all P＜0.05).Plasma Hcy and ADMA levels decreased and serum NO and eNOS levels increased in Group C 6 months after treatment,compared with those at pretreatment or 1 month after treatment,which were either lower or higher than those in Groups A and B 6 months after treatment (all P＜0.05).After adjustment for other risk factors,partial correlation analysis showed that plasma ADMA was positively correlated with plasma Hcy,while plasma ADMA and Hcy were negatively correlated with serum eNOS and NO (all P＜0.05).Conclusions Probucol in combination with Enalapril-folic acid tablets may be beneficial in improving endothelial function and mitigating the development of atherosclerosis.
