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). The HRV showed improvement. Moreover, compared with the Tai Chi group, VC, FVC, MVV, FEV1[(2.99±0.14，3.05±0.15)L], SV, step index, RMSSD[( 45.41± 9.59，52.82±7.67)ms] and HF [(2.74±0.13，2.87±0.16)ms 2] increased, while HR [(77.17±6.01, 73.83± 3.71)beats/min ] decreased in the combined group (all P < 0.05 ). Conclusion Twelve weeks of Tai Chi exercise and Tai Chi combined with inspiratory muscle resistance training can improve the cardiopulmonary function of male college students in health care classes, and the effect of the combined training is superior to that of Tai Chi training alone.

Objective:To study the impact of hyperbaric oxygen (HBO) therapy on emotion and cognitive disorders in patients with Parkinson’s disease (PD).Methods:A total of 60 patients diagnosed as PD in the Department of Neurology of Guangzhou Xinhai Hospital from July 2014 to July 2019 were selected as study objects and given HBO therapy on the basis of conventional medication. The Hamilton anxiety rating scale (HAMA), the Hamilton depression rating scale (HAMD), the unified Parkinson’s disease rating scale (UPDRS), and P300 wave were used before and after 4 courses of HBO treatment to measure the changes of patients’ medical conditions, so as to evaluate the effects of HBO on emotion, mental behavior, motor and cognitive functions of PD patients.Results:Compared with those before the 4 courses of HBO treatment, the incidences of anxiety, depression, and cognitive disorder in 60 patients dropped significantly; the HAMA and HAMD scores were significantly decreased; the incubation period of P300 wave was significantly reduced, while its amplitude was significantly increased ( P<0.05); the total UPDRS score, and the scores of UPDRSⅠ, UPDRSⅡ and UPDRSⅢ were all significantly decreased ( P<0.05); the daily levodopa equivalent dosage (DLED) was significantly reduced ( P<0.05) and the Hoehn and Yahr scale improved when the medication was "off" ( P<0.05). Conclusion:HBO therapy can effectively relieve the emotional and cognitive disorders and other non-motor symptoms in PD patients by reducing the incidence of their depression and anxiety, so as to contain the PD condition, lessen the severity of cognitive dysfunction, hence improving their activity of daily living.

Objective To evaluate the clinical value of ankle arthroscopy in diagnosis and treatment of Danis-Weber type B ankle fracture associated with injury to the distal tibiofibular syndesmosis.Methods A retrospective study was conducted of the 35 patients who had been treated at Department of Orthopaedics,Ruijin Hospital North for Danis-Weber type B ankle fracture from February 2014 to December 2016.They were 23 males and 12 females,with an average age of 43.1 years (from 18 to 65 years).Each of them underwent 4 examinations to detect whether injury to the distal tibiofibular syndesmosis was complicated or not:preoperative CT and MRI,C-ann roentgenography and ankle arthroscopy before and after internal fixation of the ankle.The diagnostic rates of the complicated injury by the 4 examinations were compared.The patients complicated with injury to the distal tibiofibular syndesmosis received surgical repair of the injury using TightRope in addition to internal fixation of the ankle,and injury to the deltoid ligament was repaired simultaneously using 3.5 mm anchor nails in case the injury was concomitant.The repair and stability of the distal tibiofibular syndesmosis were observed using ankle arthroscopy again.Results The Cotton and external rotation tests under C-arm roentgenography before surgery and after internal fixation of the ankle demonstrated that 13 cases were complicated with injury to the distal tibiofibular syndesmosis.Of the other 22 patients who had not been diagnosed with the injury by C-arm roentgenography,6,13 and 11 were diagnosed with the injury respectively by CT,MRI and ankle arthroscopy.The diagnostic rates of Danis-Weber type B ankle fracture associated with injury to the distal tibiofibular syndesmosis were 37.1％ (13/35),54.3％ (19/35),74.3％ (26/35) and 68.6％ (24/35) respectively by C-arm roentgenography,CT,MRI and ankle arthroscopy.In the sensitivity to the injury,MRI ＞ ankle arthroscopy ＞ CT ＞ C-arm roentgenography,with significant differences between them (P ＜ 0.05).The ankle arthroscopy confirmed the repair efficacy in the 24 patients complicated with injury to the distal tibiofibular syndesmosis and negative results of Cotton and external rotation tests in them.Additionally,ankle arthroscopy revealed 16 cases of injury to the deltoid ligament at the medial ankle.Conclusions Ankle arthroscopy can provide evidence for correct diagnosis and treatment of Type B ankle fracture complicated with injury to the distal tibiofibular syndesmosis,because it allows direct observation of the medial deltoid ligament of the ankle and the distal tibiofibular syndesmosis.It can be also used to assess the stability of the tibiofibular syndesmosis after repair of the injury.
