Effect of Shaolin internal qigong exercise on the surface electromyography signals of shoulder muscle groups in patients with capsulitis of the shoulder / 针灸推拿医学（英文版）

Objective: To unveil the efficacy of Shaolin internal qigong exercise in treating capsulitis of the shoulder (CS) and explore objective outcome measures by observing the changes in the surface electromyography (sEMG) signals of shoulder muscle groups after regular practice of Shaolin internal qigong exercise in CS patients. Methods: Sixty CS patients were randomized into two groups by the random number table method, with 30 cases in each group. Patients in the qigong group practiced Shaolin internal qigong exercise on a regular basis, while patients in the electroacupuncture (EA) group received EA treatment. Before and after treatment, the sEMG signals of six muscles, i.e. biceps brachii, triceps brachii, deltoid, pectoralis major, latissimus dorsi and trapezius muscles, of the affected side were recorded at 45° abduction of the shoulder, 60° forward flexion and 90° internal rotation with the elbow flexed during maximal isometric contraction, and the integrated electromyography (iEMG) of each muscle was calculated. Results: The total effective rate was 93.3％ in the qigong group, higher than 83.3％ in the EA group (P<0.05). Intra-group comparison showed that the iEMG of biceps brachii, triceps brachii, pectoralis major and deltoid muscles in the qigong group increased significantly after intervention at 45° abduction of the shoulder, 60° forward flexion and 90° internal rotation with the elbow flexed (all P<0.05), and the iEMG of trapezius and latissimus dorsi muscles decreased (both P<0.05); in the EA group, the iEMG of biceps brachii, pectoralis major and deltoid muscles increased significantly during contraction (all P<0.05), while the iEMG of triceps brachii, trapezius and latissimus dorsi muscles had no significant changes (all P>0.05). After intervention, there were significant differences in the iEMG of most of muscles between the two groups (all P<0.05), except for the iEMG of deltoid muscle at 45° of abduction of the shoulder joint during isometric contraction (P>0.05). Conclusion: Shaolin internal qigong exercise can effectively increase the motion intensity of the biceps brachii, triceps brachii, pectoralis major and deltoid muscles and reduce the compensation of the latissimus dorsi and trapezius muscles in CS patients; compared with EA, it produces a better result in improving the coordination and stability in shoulder joint movements.

The influence of oxygen partial pressure change and vascularization of rabbit wound through negative pressure wound therapy / 中华外科杂志

<p><b>OBJECTIVE</b>To investigate the effect of vacuum sealing drainage (VSD) on variation of oxygen partial pressure (PtO2) and vascularization.</p><p><b>METHODS</b>The 12 cases of rabbit's wound models were undergoing the VSD (vacuum group, n = 6) or conventional therapy (conventional group, n = 6). Variation of PtO2 was measured by oxygen partial pressure admeasuring apparatus, expression of hypoxia inducible factor 1α (HIF-1α) mRNA was measured by real-time fluorescent quantitative PCR, content of vascular endothelial growth factor (VEGF) was measured by ELISA after tissue homogenate in 7 days. Vascular endothelial cell (VEC) and new blood capillary (NBC) of hematoxylin-eosin slice of tissue were counted by using light microscope.</p><p><b>RESULTS</b>Average value of PtO2 of vacuum group was significant lower than conventional group (t = -99.780 to -5.305, P < 0.01). Expression of HIF-1α (30 minutes, 1, 6, 12 hours were 3.11 ± 0.07, 3.68 ± 0.26, 4.16 ± 0.13 and 3.91 ± 0.26 respectively) and content of VEGF (30 minutes, 1, 6, 12 hours were 103.3 ± 2.4, 134.2 ± 9.0, 167.8 ± 3.8 and 232.1 ± 9.5 respectively) of vacuum group were increased after 30 minutes and significant lower than conventional group (t = 13.038 - 80.208, P < 0.01), and both of them were reduced after 24 hours (P < 0.05). Counting numbers of VEC (2.47 ± 0.45 to 4.70 ± 0.38) and NBC (1.33 ± 0.49 to 4.33 ± 0.68) of vacuum group were increased at the same time-point and significant higher than conventional group (t = -0.670 to 16.500, P < 0.05).</p><p><b>CONCLUSIONS</b>PtO2 of wound surface could be reduced significantly by VSD. Expression of HIF-1α and content of VEGF were increased by VSD for enhancing differentiated state of VEC and construction of NBC, which were better for vascularization and wound healing.</p>

Monitoring and evaluating on cell injury in patients with severe trauma / 中华急诊医学杂志

Objective To observe the changes in cytokines, oxygen free radicals, acidulous production in serum and to investigate the effectiveness of monitoring metabolism of cells and the method for evaluating cell injury in patients with severe trauma. Method The detailed data of 117 patients rescued and managed carefully from May 2005 to February 2007 were assessed and stratified with ISS and APACHE Ⅱ , and the serum levels of arterial blood lactate(ABL) ,base deficit(BD) ,superoxide(SOD) ,lipid peroxide(LPO) ,TNF-α and IL-6 were measured in real-time according to the condition of the patient. Results The monitoring biomarkers obviously changed with injury severity which endangered the situation of patients after trauma (P < 0.05) , especially in the patients with ischemia , hypoxia, shock, iniection, SIRS, and MODS (P < 0.01). The persistence of extremely elevated levels of biomarkers meant the organ failure and fatality of patients after trauma, and there was a obvious differece between those cases and cases without elevation of biomarkers ( P < 0.01). Conclusions The outcome of patients after trauma is closely correlated with injury severity,infection and MODS,and the levels of biomarkers including ABL, SOD, IPO, TNF-a and IL-6 are useful indicators of outcome measure.
