Therapeutic effect on post-stroke spastic paralysis of upper extremity treated with combination of kinematic-acupuncture therapy and rehabilitation training / 中国针灸

OBJECTIVE@#To compare the clinical therapeutic effect on post-stroke spastic paralysis of the upper extremity between the combination of kinematic-acupuncture therapy and rehabilitation training and the combined treatment of the conventional acupuncture with rehabilitation training.@*METHODS@#A total of 60 patients of post-stroke spastic paralysis of the upper extremity at the non-acute stage were randomized into an observation group (30 cases) and a control group (30 cases, 1 case dropped off). On the base of the routine western medication and rehabilitation treatment, the kinematic-acupuncture therapy was added in the observation group and the conventional acupuncture was used in the control group. Baihui (GV 20), Dazhui (GV 14), Jiaji (EX-B 2) from T to T, Tianzong (SI 11), Jianzhen (SI 9), Jianyu (LI 15) and Quyuan (SI 13) were selected in both groups. The treatment was given once daily and the treatment for 14 days was as one course. The one course of treatment was required in this research. Separately, before treatment and in 7 and 14 days of treatment, the score of simplified Fugl-Meyer scale of the upper extremity (FMA-UE), the grade of the modified Ashworth scale (MAS) and the score of the modified Barthel index scale (MBI) were compared between the two groups.@*RESULTS@#Compared before treatment, in 7 and 14 days of treatment, FMA-UE score was increased obviously in either group (<0.01). In 14 days of treatment, FMA-UE score in the observation group was higher than that in the control group (<0.05). In 7 and 14 days of treatment, MAS grades of shoulder joint, elbow joint, wrist joint and metacarpophalangeal joint were all improved markedly in the two groups (<0.05). Compared with the grades in 7 days of treatment, MAS grades of elbow joint and metacarpophalangeal joint were improved markedly in 14 days of treatment in the two groups (<0.05). Compared with the control group, MAS grades of elbow joint and metacarpophalangeal joint were improved more markedly in the observation group in 14 days of treatment (<0.05). Compared with the score before treatment, MBI score was increased in 7 and 14 days of treatment respectively in the observation group (<0.05, <0.01). In 14 days of treatment, MBI score was increased in the control group (<0.01).@*CONCLUSION@#For the patients with post-stroke spastic paralysis of the upper extremity at the non-acute stage, the combined treatment with kinematic-acupuncture therapy and rehabilitation training obviously improves the motor function of the upper extremity and the muscle tone of elbow joint and metacarpophalangeal joint. The therapeutic effect of this combination is better than that of the combined treatment of the conventional acupuncture with rehabilitation training. Additionally, this combined therapy improves the ability of daily life activity.

Effects of matrix metalloproteinase 9 inhibition on the blood brain barrier and inflammation in rats following cardiopulmonary resuscitation / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>Neuroprotective strategies following cardiopulmonary resuscitation (CPR) are an important focus in emergency and critical care medicine. Matrix metalloproteinases (MMPs), especially MMP9 attracted much attention because of its function in focal brain ischemia/reperfusion injury. In the focal cerebral ischemia model in rats, SB-3CT can suppress the expression of MMP9, relieving brain edema, and there was no studies on global cerebral ischemia-reperfusion injury after CPR.</p><p><b>METHODS</b>One hundred and twenty rats were randomly assigned to sham-operated (n = 40), resuscitation treatment (n = 40), and resuscitation control (n = 40) groups. Sham-operated group rats were anesthetized only and intubated tracheally, while the resuscitation treatment and resuscitation control groups also received cardiac arrest by asphyxiation. In the resuscitation treatment group, SB-3CT was injected intraperitoneally after restoring spontaneous circulation (ROSC), defined as restoration of supraventricular rhythm and mean arterial pressure (MAP) > or = 60 mm Hg for more than 5 minutes. The resuscitation control group also implemented ROSC without injection of SB-3CT. The rats were executed and samples were taken immediately after death, then at 3, 9, 24, and 48 hours (n = 8). Brain tissue expression of MMP9 protein, MMP9 mRNA, water content, Evans blue content, TNF-alpha, IL-1, and IL-6 was measured, and the brain tissue ultramicrostructure studied with electron microscopy.</p><p><b>RESULTS</b>In the resuscitation control group, brain tissue expression of MMP9 protein and mRNA, water content, Evans blue content, TNF-alpha, IL-1, and IL-6 were significantly elevated at 3 hours, and peaked at 24 hours after resuscitation, when compared with the sham-operated group (P < 0.05). Tissue ultramicrostructure also changed in the resuscitation control group. By contrast, although all these indexes were increased in the resuscitation treatment group compared with the sham-operated group (P < 0.05), they were lower than in the resuscitation control group (P < 0.05).</p><p><b>CONCLUSIONS</b>Expression of MMP9 protein and mRNA, water content, Evans blue content, TNF-alpha, IL-1, and IL-6 increased in rat brain tissue after CPR, indicating disruption of the blood-brain barrier and excess inflammatory reaction. MMP9 expression was reduced with SB-3CT, resulting in reduced brain injury.</p>

Comparison of three analgesic methods for postoperative pain relief and their effects on plasma interleukin-6 concentration following radical surgery for gastric carcinoma / 南方医科大学学报

<p><b>OBJECTIVE</b>To compare the efficacy of preemptive epidural analgesia combined with postoperative epidural analgesia, postoperative epidural analgesia alone and intravenous analgesia for postoperative pain relief and their effects on plasma interleukin-6 (IL-6) concentration following radical surgery for gastric carcinoma.</p><p><b>METHODS</b>Sixty-six patients with gastric carcinoma scheduled for gastrectomy were randomly divided into 3 groups, namely group P (n=22), group E (n=22) and group V (n=22), to receive preemptive epidural analgesia combined with postoperative epidural analgesia, exclusive postoperative epidural analgesia, and exclusive postoperative intravenous analgesia, respectively. Hemodynamic data were recorded for all the patients during the operation, and visual analogue scale (VAS) was used to assess the pain intensity at 4, 8, 16, 24, 48 and 72 h after surgery. Plasma IL-6 concentration was determined before surgery and at 24, 48, 72 h after surgery.</p><p><b>RESULTS</b>No significant changes occurred in the hemodynamics during the preoperative periods. VAS and IL-6 were lower in group P than in group E and V, and group E had lower measurement than group V (P<0.05).</p><p><b>CONCLUSION</b>Preemptive epidural analgesia combined with postoperative epidural analgesia provides more satisfactory pain relief and more effectively prevents IL-6 increment than exclusive epidural analgesia or intravenous analgesia after gastrectomy for gastric carcinoma.</p>
