Effect of lower thoracic epidural block on intestinal epithelial cell apoptosis during hemorrhagic shock and resuscitation in rats / 临床麻醉学杂志

Objective To investigate the effect of lower thoracic epidural block on intestinal epithelial cell apoptosis during hemorrhagic shock and resuscitation in rats.Methods Sixty-four male SD rats placed with lower thoracic epidural catheter were randomly divided into four groups (n=1 6 each):group Sham (sham operation),group HSR (hemorrhagic shock and resuscitation),group NS (hemorrhagic shock and resuscitation+epidural saline 100 μl/kg),and group TEA (hemorrhagic shock and resuscitation+epidural 0.075% ropivacaine 100 μl/kg).The hemorrhagic shock was made described by Chaudry.Rats were resuscitated by transfusing shed blood and normal saline 60 min after hemorrhagic shock.Malondialdehyde (MDA)content,superoxide dismutase (SOD)activity, and protein expression of Bax and Bcl-2 in intestinal epithelium were detected,and epithelial apoptosis index was calculated at 2 h after resuscitation.Results Compared with group Sham,intestinal epithe-lial MDA,Bax expression and epithelial apoptosis were significantly increased,while SOD activity were markedly decreased in groups HSR,NS and TEA (P<0.05).Compared with groups HSR and NS,intestinal epithelial MDA,Bax expression and epithelial apoptosis were significantly decreased, while SOD activity and Bcl-2 expression were markedly increased in group TEA (P <0.05 ). Conclusion Lower thoracic epidural block can enhance the antioxidant and anti-apoptotic ability,and inhibit the oxidative stress and cell apoptosis of intestinal epithelium.Therefore,it can promote the survival rate after hemorrhagic shock and resuscitation through protecting intestinal barrier.

Clinical Observation of Shenqiluotong Capsule on 100 Patients with Diabetes Mellitus Crura Angiopathy / 中国中医药信息杂志

Objective To observe the clinical effect of Shenqiluotong capsule on diabetes mellitus crura angiopathy.Methods Two hundred patients with diabetes mellitus crura angiopathy were randomly divided into two groups.One hundred patients in the treatment group were administrated Shenqiluotong capsule and enteric-coated aspirin tablet orally.One hundred patients in the control group were only given enteric-coated aspirin tablet orally.The effectiveness,clinical symptom and sign,glucose,blood fat,hemodynamics,crura artery diameter,peak value rate,blood flow volume and side effect were observed before and after treatment.Results The total effective rate in the treatment group and the control group were 89 % and 71% respectively(P
