ABSTRACT
Objective To observe the effects of different anesthetic techniques on T-lymphocyte subsets in patients with cardia cancer. Methods Thirty-two patients undergoing elective radical operation for cardia cancer who had been average assigned into two groups by random digits table, group Ⅰ :general anesthesia;group Ⅱ :epidural anesthesia combined with general anesthesia (16 cases in each group).Peripheral blood T-lymphocyte subsets were measured before induction, after anesthesia, end of operation, 1d,3 d after operation. Results CD3,CD4,CD8 and CD4/CD8 all decreased in two groups after anesthesia,end of operation and 1 d after operation than before induction (P < 0.05). The index almost returned to the baseline values at 3 d after operation in group Ⅱ [ (60.75 ± 4.22 )%, (39.65 ± 3.64)%, (25.90 ± 1.17 )%,1.57 ±0.15](P >0.05),while in group Ⅰ still lower [(55.83 ±5.20)%, (35.15 ±5.65)%, (23.00 ±1.03 )%, 1.47 ± 0.35 ](P< 0.05 ). The two groups ontrast had significant deviation at 3 d after operation (P<0.05). Conclusion Epidural anesthesia combined with general anesthesia can reduce depression of Tlymphocyte subsets induced by surgical trauma and anesthesia.
ABSTRACT
Objective To determine the effects of different anesthetic techniques on T-lymphocyte subsets in patients with esophageal carcinoma. Methods Forty patients were randomly assigned into general anesthesia group (group Ⅰ),or combined generae anesthesia with epidural anesthesia group(group Ⅱ). Peripheral blood CD3, CD4,CD8 were measured before induction ( T1 ), after anesthesia ( T2 ), end of operation ( T3 ), 1d ( T4 ), 3d ( T5 ) after surgery. Resolts CD3,CD4,CD8,CD4/CD8 decreased at T2 in the two groups. In group Ⅱ ,CD3,CD4,CD8,CD4/CD8 ratio almost returned to the baseline values at T4 ,while group Ⅰ did not. Conclusion Epidural anesthesia combined with general anesthesia can reduce depression of T-lymphocyte subsets induced by surgical trauma and anesthesia, and is the anesthetic tecnique of choice for cancer patients undergoing major operation.
ABSTRACT
Objective To study the false positive of enzyme linked immunoinhibition continuous assays to detect CK-MB in clinic,to reasonably explain the results of detection and to get correctly the project of solving.Methods A total of 125 serum specimen of non-myocardial infarction patients were detected by enzyme linked immunoinhibition continuous assays,in retrospective study.To analyze the factors which made the CK-MB enzymatic activity unit pseudo-rising.Results Total CK-MB enzymatic activity was low in 86 serum specimen of adult patients with non-myocardial infarction,but in the patients with tumor,encephalic infarction and allergic disorder the pseudo-positive ratio of the CK-MB enzymatic activity was high.There were 53 cases, in which CK-MB activity accounted for 6%-21% enzymatic activity of CK, and 6 cases accounted for more than 38% in 59 cases in which the CK-MB activity was more than 5% enzymatic activity of CK.In 38 neonate cases, the enzymatic activity of CK ranged from 145U/L to 1974U/L,In 1 case of neonatal respiratory distress syndrome CK-MB activity accounted for more than 90% enzymatic activity of CK.Another haemolytic sample led to false positive result.Conclusion The phenomenon of enzymatic activity rising in the serum specimen of non-myocardial infarction patients may be caused by the factors of lots CK, CK-BB and AK in serum.Those materials maybe have effects on the action between McAb and M subunit of the CK.Some non-inhibit CK-M and the M subunit with B subunit may participate the enzymatic activity together.Because of the shortcoming of method,the single assay should not be taken as the diagnostic basis.
