Objective: To compare the effects of 12 week Tai Chi combined with inspiratory muscle resistance training on cardiopulmonary function among male college students in health care classes, so as to provide a reference for improving the cardiopulmonary function of the students. Methods: From March to May 2025, 72 male students from the physical education health care classes at North University of China were selected and randomly divided into the control group ( n =25), the Tai Chi group ( n = 24), and the Tai Chi combined with inspiratory muscle resistance training group (combined group, n =23) by random number table method. The control group maintained normal living habits, the Tai Chi group underwent 12 weeks of Tai Chi exercise (three sessions per week, 90 minutes per session), and the combined group received 12 weeks of Tai Chi training (three sessions per week, 60 minutes per session) combined with 30 minutes of inspiratory muscle resistance training. Cardiovascular function[heart rate(HR), stroke volume(SV), cardiac output(CO), mean systolic pressure(MSP), mean diastolic pressure(MDP), vascular elastic dilatation coefficient (VDC), total peripheral resistance (TPR), viscosity (V)], pulmonary function [vital capacity (VC), forced vital capacity (FVC), maximum minute ventilation volume (MVV), forced expiratory volume in one second (FEV1), FEV1/FVC] and heart rate variability (HRV) [HR, standard deviation of the normal to normal intervals (SDNN), root mean square successive difference (RMSSD), low frequency (LF), high frequency (HF), LF/HF] of the three groups of subjects were tested before and after the experiment, the data were analyzed using analysis of covariance. Results: There were no statistically significant differences in any indicators among the three groups before the intervention ( F =0.00-2.49, all P >0.05). After the intervention, except FEV1/FVC, MDP and V, there were statistically significant differences of pulmonary function, cardiovascular function and HRV indicators among the three groups ( F =4.38-62.93, all P <0.05). Compared with the control group [(VC ( 3.28± 0.30)L, FVC (3.20±0.29)L, MVV (107.01±9.55)L, SV (65.68±2.34)mL, CO (5.36±0.18)L/min, VDC (0.40±0.03), step index (50.64±3.11), MSP (133.17±6.47)mmHg, TPR (1 281.34±100.78)dyn ·s ·cm -5 ], the VC [(3.43±0.24, 3.69±0.21)L], FVC [(3.34±0.16, 3.46±0.20)L], MVV [(112.54±8.95, 117.11±6.37)L], SV [(71.75±4.20, 75.39±3.71)L/time], CO[( 5.53± 0.14, 5.58±0.15)L/min], VDC (0.43±0.03, 0.44±0.02) and step index (53.38±5.77, 56.17±4.91) in the Tai Chi group and the combined group significantly increased, while the MSP [(120.17±6.42, 118.04±12.99)mmHg] and TPR [( 1 227.01 ±107.25, 1 217.69±64.93)dyn ·s ·cm -5 ] significantly decreased (all P <0.05).

Objective:To investigate the predictive value of N-terminal pro-brain natriuretic peptide (NT-proBNP), cystatin C (CysC) and interleukin-17 (IL-17) in relapse after radiofrequency catheter ablation (RFCA) in elderly patients with persistent atrial fibrillation.Methods:The clinical data of 69 elderly patients with persistent atrial fibrillation underwent RFCA (atrial fibrillation group) in Shanghai Pudong New Area People′s Hospital from January 2020 to December 2021 were retrospectively analyzed. Additionally, 69 healthy subjects underwent physical examinations during the same period were selected as the healthy control group. The levels of serum NT-proBNP, CysC and IL-17 were detected. The relapse after RFCA was recorded. Multivariate Logistic regression was used to analyze the independent risk factors of relapse after RFCA in elderly patients with persistent atrial fibrillation. The values of NT-proBNP, CysC and IL-17 in predicting the relapse after RFCA in elderly patients with persistent atrial fibrillation were evaluated by the receiver operating characteristics (ROC) curve.Results:The serum NT-proBNP, CysC and IL-17 before operation and 7 d after operation in atrial fibrillation group were significantly higher than those in healthy control group: (789.41 ± 89.22) and (358.96 ± 50.24) ng/L vs. (114.38 ± 32.56) ng/L, (1.42 ± 0.30) and (1.20 ± 0.21) mg/L vs. (0.98 ± 0.17) mg/L, (12.48 ± 3.21) and (9.83 ± 2.58) ng/L vs. (7.85 ± 2.13) ng/L, and there were statistical differences ( P<0.05); compared with healthy control group, there were no statistical difference in the indexes 1 and 3 months after operation ( P>0.05). The serum NT-proBNP, CysC and IL-17 7 d, and 1, 3 month after operation in atrial fibrillation group were significantly lower than those before operation, and there were statistical differences ( P<0.05). The 69 patients were followed up for 1 year, with 20 cases experiencing relapse and 49 cases not experiencing relapse. There were no statistical differences in the serum NT-proBNP, CysC and IL-17 before operation and 7 d after operation between relapse patients and non-relapse patients ( P>0.05); the serum NT-proBNP, CysC and IL-17 1 and 3 months after operation in relapse patients were significantly higher than those in non-relapse patients, 1 month after opertion: (132.49 ± 32.84) ng/L vs. (115.56 ± 27.61) ng/L, (1.10 ± 0.15) mg/L vs. (0.99 ± 0.12) mg/L and (8.59 ± 1.76) ng/L vs. (7.65 ± 1.58) ng/L; 3 months after operation: (140.37 ± 32.83) ng/L vs. (119.90 ± 25.44) ng/L, (1.17 ± 0.20) mg/L vs. (1.02 ± 0.15) mg/L and (9.12 ± 2.31) ng/L vs. (7.74 ± 1.80) ng/L, and there were statistical differences ( P<0.05 or<0.01). Multivariate Logistic regression analysis result showed that the serum NT-proBNP, CysC and IL-17 1 and 3 months after operation were the independent risk factors of relapse after RFCA in elderly patients with persistent atrial fibrillation ( P<0.01). ROC curve analysis result showed that the area under curve (AUC) of the serum NT-proBNP, CysC, IL-17 and the combination of three indexes 3 months after operation in predicting the relapse after RFCA in elderly patients with persistent atrial fibrillation were higher than those at 1 month after operation (0.813 vs. 0.783, 0.770 vs. 0.721, 0.725 vs. 0.717 and 0.927 vs. 0.833; P<0.05), the AUC of combination of three indexes 1 and 3 months after operation was significantly higher than that of individual indexes at each time point ( P<0.05). Conclusions:The elevated levels of serum NT-proBNP, CysC and IL-17 after operation in elderly patients with persistent atrial fibrillation are closely related to the relapse after RFCA, and can be used as biochemical indicators to predict recurrence.

Objective:To investigate the correlation between different degrees of white matter hyperintensities (WMHs) and outcome after intravenous thrombolysis (IVT) in patients with acute ischemic stroke.Methods:Patients with AIS received intravenous thrombolytic therapy with standard dose of alteplase in the First Hospital of Putian City from January 2019 to June 2022 were retrospectively included. The Fazekas scale was used to score the WMHs shown on MRI, and the patients were divided into without or mild WMH group and moderate-to-severe WMH group. The clinical baseline data and the clinical outcome after 3 months of the two groups were compared. The poor outcome was defined as the modified Rankin scale score >2. Multivariate logistic regression analysis was used to determine the influence of the severity of WMHs on the outcome after intravenous thrombolysis. Results:A total of 103 patients with AIS were included. Their age was 64.85±10.89 years old, and 66 (64.1%) were men. There were 60 patients (58.3%) in the without or mild WMH group, and 43 (41.7%) in the moderate-to-severe WMH group. There were significant differences in age, body mass index, systolic blood pressure, baseline National Institutes of Health Stroke Scale (NIHSS) scores, as well as the proportion of patients with hypertension, smoking, hemorrhagic transformation and poor functional outcome at 3 months after onset in different degrees of WMH groups (all P<0.05). There were 73 patients (70.9%) in the good outcome group and 30 (29.1%) in the poor outcome group. There were significant differences in age, body mass index, baseline NIHSS score, WMH score, as well as the proportion of patients with hypertension, large atherosclerotic stroke and symptomatic intracranial hemorrhage between the two groups ( P<0.05). Multivariate logistic regression analysis showed that after adjusting for confounding factors, moderate-to-severe WMHs were the independent risk factors for the poor outcome at 3 months after intravenous thrombolysis (odds ratio 3.810, 95% confidence interval 1.298-1.124; P=0.015). Conclusion:Moderate-to-severe WMHs are associated with the poor outcome in patients with AIS at 3 months after intravenous thrombolysis.

Jiawei Xiaoyao San (JWXYS) has shown excellent clinical efficacy in anxiety disorder, but has not yet attracted widespread attention. The animal experiments, clinical trials and mechanism studies of JWXYS were reviewed in this article, which may provide a reference for developing new anxiolytic drugs based on this prescription. The literature was searched in PubMed and CNKI and the documents written in English or with English abstracts were selected. JWXYS could reduce the anxiety symptoms of patients alone and reduce the adverse reactions when it is used in combination with other drugs in the clinic. In preclinical studies, JWXYS also showed therapeutic effects in reducing anxiety-like behavior. The mechanisms may include improving the hypothalamic-pituitaryadrenal (HPA) axis and hormone disorders, increasing neurotransmitter content, neurogenesis, and regulating the synthesis of related enzymes. This article shows that JWXYS could effectively treat anxiety disorders by regulating the central nervous system. In the future, with the participation of more researchers, it is expected to develop innovative drugs for the treatment of anxiety disorders based on JWXYS.

Insufficient catalytic efficiency of flavonoid 6-hydroxylases in the fermentative production of scutellarin leads to the formation of at least about 18% of by-products. Here, the catalytic mechanisms of two flavonoid 6-hydroxylases, CYP82D4 and CYP706X, were investigated by molecular dynamics simulations and quantum chemical calculations. Our results show that CYP82D4 and CYP706X have almost identical energy barriers at the rate-determining step and thus similar reaction rates, while the relatively low substrate binding energy of CYP82D4 may facilitate product release, which is directly responsible for its higher catalytic efficiency. Based on the study of substrate entry and release processes, the catalytic efficiency of the L540A mutation of CYP82D4 increased by 1.37-fold, demonstrating the feasibility of theoretical calculations-guided engineering of flavonoid 6-hydroxylase. Overall, this study reveals the catalytic mechanism of flavonoid 6-hydroxylases, which may facilitate the modification and optimization of flavonoid 6-hydroxylases for efficient fermentative production of scutellarin.

OBJECTIVE: To summarize the effectiveness of Kirschner wire buckling combined with bone fixation in the treatment of metacarpal avulsion fracture. METHODS: The clinical data of 35 patients of metacarpal avulsion fracture admitted between March 2017 and June 2022 were retrospectively analyzed. There were 22 males and 13 females; the age ranged from 20 to 55 years, with an average of 31.6 years. There were 17 cases of the second metacarpal avulsion fracture, 6 cases of the fourth metacarpal avulsion fracture, and 12 cases of the fifth metacarpal avulsion fracture. The causes of injury included 21 cases of strangulation, 8 cases of sprain, and 6 cases of sports injury. X-ray film examination showed that the size of the avulsion fracture of metacarpal bone ranged from 0.30 cm×0.20 cm to 0.55 cm×0.45 cm. The total active motion (TAM) of the injured finger before operation was (154.00±17.38)°. The time from injury to operation was 3-10 days, with an average of 5.8 days. Follow-up regularly after operation, X-ray film and CT examination were performed to evaluate fracture healing and TAM of injured finger was measured. The finger function was evaluated by the trial standard of upper limb function evaluation of Hand Surgery Society of Chinese Medical Association. RESULTS: All the incisions healed by first intention. All 35 patients were followed up 9-36 months, with an average of 28 months. All metacarpal avulsion fractures achieved bony healing, and the healing time was 4-6 weeks, with an average of 4.8 weeks. The metacarpophalangeal joint of the patient was stable, without stiffness, and the flexion and extension activities were good. At last follow-up, the TAM of the injured finger reached (261.88±6.23)°, which was significantly different from that before operation ( t=-35.351, P<0.001). The finger function was evaluated according to the trial standard of upper limb function evaluation of the Society of Hand Surgery of Chinese Medical Association, and 33 cases were excellent and 2 cases were good, with an excellent and good rate of 100%. CONCLUSION The treatment of metacarpal avulsion fracture with Kirschner wire buckling combined with bone fixation has the advantages of less trauma, firm fixation, and less interference to the soft tissue around metacarpophalangeal joints, which is a good alternative method for the metacarpal avulsion fracture.

Objective:To explore the expression of long non-coding RNA-myeloid differentiation factor 88 (lnc-MyD88) and its relationship with the prognosis of patients with epithelial ovarian cancer (EOC).Methods:A total of 70 EOC patients who underwent initial cytoreductive surgery and platinum-based drugs combined with paclitaxel for 6 to 8 courses were selected at Sichuan Cancer Hospital from January 2016 to January 2019. The fresh cancer tissue specimens were collected. In addition, 28 fresh normal ovarian tissues from patients who underwent surgery for benign gynecological diseases during the same period were collected as control group. Reverse transcription (RT) and real-time quantitative polymerase chain reaction (qPCR) were used to detect the expression of lnc-MyD88 and myeloid differentiation factor 88 (MyD88) mRNA in EOC tissues and normal ovarian tissues. The correlation between the expression of lnc-MyD88 and MyD88 mRNA in EOC was analyzed by Pearson′s correlation coefficient. The relationship between lnc-MyD88 expression and clinicopathological characteristics of patients with EOC was analyzed. Kaplan-Meier method was used to calculate the survival rate of patients. The log-rank test was used for univariate survival analysis, and Cox proportional hazard model was used for multivariate survival analysis.Results:(1) RT-qPCR showed that the relative expression level of lnc-MyD88 and MyD88 mRNA in EOC were 0.009 (0.000-0.049) and 0.001 (0.000-0.006), respectively, which were significantly higher than those of normal ovarian tissues (all P<0.01); Pearson′s correlation coefficient showed that the expression of lnc-MyD88 and MyD88 mRNA in EOC was positively correlated ( r2=0.610, P<0.01). (2) The high expression rate of lnc-MyD88 in EOC patients with lymph node metastasis, distant metastasis and chemotherapy resistance (71%, 64% and 70%, respectively) were significantly higher than the patients in control group (41%, 40% and 35%, respectively; all P<0.05). There were no statistically significant in the high expression rate of lnc-MyD88 in EOC patients with different ages, pathological types, pathological grades, surgical pathological stages, postoperative residual lesion size, and ascites cancer cells (all P>0.05). (3) Univariate analysis showed that surgical pathological staging, lymph node metastasis, distant metastasis, postoperative residual tumor size, and high expression of lnc-MyD88 and MyD88 mRNA significantly affected the progression-free survival (PFS) and overall survival (OS) of EOC patients (all P<0.05), ascites cancer cells were the risk factors that significantly affected PFS in EOC patients ( P=0.040); multivariate analysis showed that surgical pathological staging and high expression of lnc-MyD88 and MyD88 mRNA were independent factors affecting PFS and OS in EOC patients (all P<0.05), the size of residual lesions after surgery was an independent factor affecting PFS in EOC patients ( P=0.001). Conclusions:The level of lnc-MyD88 expression in ovarian cancer tissues was significantly increased. Lnc-MyD88, as a molecular marker for the poor prognosis of EOC, is related to the expression of MyD88 in EOC, and may be involved in its expression regulation, thereby affecting the survival and prognosis of EOC patients.

Objective:To investigate the application and curative effect of fat grafting in supraorbital area in double blepharoplasty in patients with negative vector of the eyelid- globe.Methods:From January 2019 to January 2020, 78 patients who came to Fuzhou Meilai Huamei Beauty Hospital for double blepharoplasty were collected as patients with negative eyelid- globe vector. The patients were randomly divided into 2 groups, with 42 cases in the combined group and 36 cases in the simple group. The combined group underwent double blepharoplasty combined with fat grafting in the supraorbital area, and the simple group only underwent double blepharoplasty.Results:The postoperative follow-up was 3-12 months, with an average follow-up of 6 months. The efficacy of the combined group and the simple group was compared. There was no surgical complications in both groups. In improving the eyelid-globe vector, the combined group was higher than that of the simple group. The overall satisfaction of the combined group was higher than that of the simple group. Among them, the satisfaction of eye appearance, self-confidence, mental health, surgical results, decision-making and facial rejuvenation were all higher than those of the simple group, and there was no difference in the impact on early life between the two groups.Conclusions:Double blepharoplasty undergoing fat grafting in the supraorbital area at the same time are safe and conforms to the aesthetic standard. The patients are satisfied with the postoperative effects.
