ABSTRACT
Objective To investigate the effects of transcutaneous electrical acupoint stimulation (TEAS) and electro-acupuncture (EA) combined with local anesthesia on cerebral blood flow (CBF) and Brain function in CAS patients.Methods Eighty cases of CAS were randomly as signed into EA group (group A),TEAS group (group T) and sham group (group C).Patients in group A received EA at acupoints of Shuigou (GV26) and Baihui (GV20),Hegu (L14) and Waiguan (TE5) at the same side of the stenting before 30 min of operation.Patients in group T received TEAS at the same acupoints through self-adhesive skin electrodes.In group T and group A,stimulations were continued until the end of the operation.The patients in group C did not received EA or TEAS.Blood pressure (BP) and heart rate (HR) were maintained at + 10％-20％ of baseline.Preoperative and postoperative average Vm,PI,RI of middle cerebral artery were measured.The occurrence of hyperperfusion and preoperative and postoperative scores at 1 week,1 month,3 months National Institute of Health Stroke Scale and Global Assessment Scale were recorded.Results The Vm of groups A and T was significantly less than group C (P＜0.05).The incidence of hyperperfusion of groups A and T were 3.7％,0％ and 25.0％ respectively (P＜0.05).NIHSS score of group A and group T were lower than those of group C during postoperative 1 week,1 month,3 month (P＜0.05),while the difference between groups A and T had no statistical significance.GES score of group A and group T during postoperative 1 week improved significantly than that of group C (P＜0.05).Conclusion Both TEAS and EA combined with local anesthesia in CAS operation could reduce the increase of postoperative cerebral blood flow and the incidence of postoperative hyperperfusion,and obviously improve brain function during postoperative 1 week.Both TEAS and EA combined with local anesthesia could be a worthwhile anesthesia method in CAS patients.
ABSTRACT
Objective To study the significance of serum interleukin(IL)-18,IL-22 and IL-23 levels in rheumatoid arthritis.Methods 40 patients of rheumatoid arthritis w ho received therapy from December 2014 to December 2016 in our hospital were selected,and 40 cases of healthy people in our hospital for the same pe-riod were selected as a control group,the expressions of serum IL-18,IL-22 and IL-23 were compared between the two groups;The relationship between the serum IL-18,IL-22,IL-23 and the severity of rheumatoid arthri-tis,before and after treatment and clinical indicators were analyzed.Results The serum IL-18[(741.82 ± 45.60)pg/mL],IL-22[(62.34 ± 3.72)pg/mL]and IL-23[(141.73 ± 18.31)pg/mL]in rheumatoid arthritis group were higher than that of control group[(231.28 ± 26.71),(37.26 ± 3.91),(48.28 ± 5.70)pg/mL],and the difference has statistical significance(P<0.05);the serum IL-18,IL-22 and IL-23 in highly active group rheumatoid arthritis patients were significantly higher than that of moderate active group and stable/mild ac-tive group,serum IL-18,IL-22 and IL-23 in the moderate active group were significantly higher than that of stable/mild active group,and the difference has statistical significance(P<0.05);after treatment,the serum levels of IL-18,IL-22 and IL-23 in patients with rheumatoid arthritis were significantly lower than those before treatment,and the difference has statistical significance(P< 0.05);the results of correlation analysis show that there was a positive correlation between the serum IL-18 and joint tenderness index,joint swelling index, C reactive protein and bone destruction score(P<0.05),and there was a positive correlation between the ser-um IL-22,IL-23 and VAS score,the time of morning stiffness,joint pain index,swelling index,platelet count,C reaction protein and done destruction score(P<0.05).Conclusion The serum IL-18,IL-22,and IL-23 are closely related to the severity of rheumatoid arthritis,which can increase with the aggravation of disease,and it also helps to assess the effectiveness of disease treatment,application value is high.
ABSTRACT
@#Objective To observe the effects of repeated dosing of 6% hydroxyethyl starch (130/0.4) or 7.5% sodium chloride on brain edema after experimental intracerebral hemorrhage (ICH) in rats. Methods 167 male SD rats were divided into four groups randomly: Sham operation group (S, n=20), ICH control group (M, n=38), 7.5% sodium chloride group (N, n=55) and 6% hydroxyethyl starch group (H, n=54). The model of the ICH was established with stereotactically infusing 50 μl of the autologous femoral artery blood into the right caudate nucleus. group N and group H received 7.5% sodium chloride 5 ml/kg and 6% hydroxyethyl starch 30 ml/kg at 2 h, 24 h, 48 h and 72 h after operation respectively. The tumor necrosis factor-alpha (TNF-α), interleukin-6 (IL-6), superoxide dismutase (SOD) and malondialdehyde (MDA) in the tissue around the hemorrhage were measured at different time point. Results The IL-6 in group N was significantly more than that in group M at 24 h and 72 h after infusion (P<0.05), and the TNF-α in group H was less than that in group M at 24 h and 48 h after infusion (P<0.05). The SOD in group M decreased to the bottom at 48 h and 72h after ICH. SOD in group N and group H at 24 h, 48 h and 72 h after infusion was both significant more than that in group M (P<0.05). MDA in group H at 72 h after infusion was less than that in group M (P<0.05). Conclusion Repeated infusion of 6% hydroxyethyl starch (130/0.4) or 7.5% sodium chloride can decrease inflammatory response of brain tissue after ICH, which may protect brain from oxidative damage.
ABSTRACT
Objective To investigate the effects of repeated administrations of 6% hydroxyethy] starch (HES) 130/0.4 or 7.5 % NaCl (NS) on brain water content (BWC) after experimental intracerebral hemorrhage (ICH) in rats.Methods One hundred and sixty-seven male SD mrs weighing 260-300 g were randomly divided into 4 groups: group Ⅰ sham operation (S) (n = 20) ;group Ⅱ ICH (n = 38) ;group Ⅲ NS + ICH (n = 55) and group Ⅳ HES + 1CH (n = 54). The animals were anesthetized with intraperitoneal 10% chloral hydrate 400 mg/kg. Experimental ICH was produced by injection of fresh autologous blood 50 μl into right caudate nucleus. In group NS (group Ⅲ) 7.5% NaCl 5 ml/kg and in group HES (group Ⅳ) 6% HES 30 ml/kg were injected at 2, 24, 48 and 72 h after ICH. In group S and ICH (group Ⅰ and Ⅱ) 5 animals were killed at 2, 24, 48 and 72 h after ICH, while in group Ⅲ (NS) and Ⅳ (HES) 5 animals were killed at 2, 24, 48 and 72 h after ICH, immediately before and after NS/HES infusion for determination of ipsilateral and contralateral cerebral cortex and basal ganglion, weight and W/D weight ratio. Rosenberger behavior scores and survival rates were also recorded. Results In group Ⅲ (NS + ICH) and Ⅳ (HES + ICH) the water content of ipsilateral cerebral cortex and basal ganglion was significantly lower than in group Ⅱ (ICH). Rosenberger behavior scores at 24 h and 48 h after ICH were significantly lower in group NS and HES than in group Ⅱ (ICH) . The survival rates at 24, 48 and 72 h after ICH were significandy lower in group Ⅱ than in group NS and HES, especially at 72 h in group HES. Conclusion Repeated administrations of 6% HES 130/0.4 or 7.5% NaCl can ameliorate brain edema after ICH.
