Objective To investigate the effects of sevoflurane preconditioning on the expression of pulmonary angiotensin converting enzyme (ACE) mRNA in lung tissues during lung ischemia-reperfusion (I/R) in rats.Methods Fifty-four male Sprague-Dawley rats,weighing 250-320 g,were randomly divided into 3 groups (n =18 each):sham operation group (group S),I/R group and sevoflurane preconditioning group (group SP).The animals were anesthetized,tracheostomized and mechanically ventilated.Lung I/R was induced by clamping the left pulmonary hilum for 45 min followed by 120 min reperfusion in groups I/R and SP.While the left pulmonary hilum was only isolated but not ligated in group S.2.1％ sevoflurane was inhaled for 30 min,and lung I/R was induced 10 min after the end of inhalation in group SP.Six rats in each group were chosen at 30,60 and 120 min of reperfusion and sacrificed,lungs were removed for determination of wet/dry lung weight (W/D) ratio,MPO activity (by colorimetric method) and the expression of ACE mRNA (by RT-PCR) and for microscopic examination in lung tissues.Results Compared with group S,the W/D ratio,MPO activity and expression of ACE mRNA were significantly increased in groups I/R and SP (P ＜ 0.05).Compared with group I/R,the W/D ratio,MPO activity and expression of ACE mRNA were significantly decreased in group SP (P ＜ 0.05).Microscopic examination showed that the pathologic changes were significantly attenuated in group SP compared with group I/R.Conclusion Sevoflurane preconditioning can reduce lung I/R injury through downing-regulating the expression of ACE mRNA in rats.

OBJECTIVE:To observe the clinical efficacy and safety of sodium hyaluronate combined with glucosamine in the treatment of knee osteoarthritis. METHODS:1 220 patients with knee osteoarthritis were randomly divided into observation group and control group. The patients in control group were treated with Sodium hyaluronate injection alone,once a week;while the ob-servation group was additionally and orally treated with Glucosamine hydrochloride capsules two tablets,three times a day. The course of treatment was 5 weeks in both groups. The relevant physicotherapeutics and oral medication in the treatment of the dis-ease should be stopped. The clinic efficacy,visual analog scale(VAS)and lysholm knee score before and after treatment,and inci-dence of adverse reaction were observed. RESULTS:Total effective rate of observation group was significantly higher than control group,with statistically significant difference(P<0.05). After treatment,VAS and lysholm knee scores in both groups were signifi-cantly lower than before,and observation group was lower than control group,with significant differences(P<0.05). There were no severe adverse reactions during treatment. CONCLUSIONS:Sodium hyaluronate combined with glucosamine has more signifi-cant clinical efficacy in the treatment of knee osteoarthritis than sodium hyaluronate alone,with good safety.

Objective To study the relationship between the diabetic autonomic neuropathy (DAN) and the cerebrovascular disease. Methods The heart rate variability (HRV) was measured in 77cases of type 2 diabetes 〔49 men, 28 women, age (63.1?11.4)years〕. Forty-one cases suffered from DAN (group A), 36 cases without DAN (group B) according to the results of HRV. All the cases received the examination with transcranial Doppler ultrasonography (TCD). Results Compared with group B, the abnormality detected with TCD was higher in group A, cerebrovascular compliance was commonly decreased and cerebrovascular stenosis was also extensively observed. Conclusion DAN seems to be one of the risk fcators in inducing cerebrovascular disease.
