AIM To study relationship of injury induced by nitric oxide, oxidation, peroxidation, lipoperoxidation with chronic cholecystitis. METHODS The values of plasma nitric oxide (PNO), plasma vitamin C (P-VC), plasma vitamin E ( P-VE ), plasma β-carotene ( P-β-CAR ), plasma lipoperoxides (P-LPO), erythrocyte superoxide dismutase (E-SOD), erythrocyte catalase (ECAT), erythrocyte glutathione peroxidase (E-GSHPx) activities and erythrocyte lipoperoxides (ELPO) level in 77 patients with chronic cholecystitis and 80 healthy control subjects were determined, differences of the above average values between the patient group and the control group and differences of the average values between preoperative and postoperative patients were analyzed and compared, linear regression and correlation of the disease course with the above determination values as well as the stepwise regression and correlation of the course with the values were analyzed. RESULTS Compared with the control group, the average values of P-NO, P-LPO, E-LPO were significantly increased ( P < 0.01 ), and of P-VC, P-VE, P-β-CAR, E-SOD, E-CAT and E-GSH-Px decreased ( P < O. 01 ) in the patient group. The analysis of the linear regression and correlation showed that with prolonging of the course, the values of P-NO, P-LPO and E-LPO in the patients were gradually ascended and the values of P-VC, P-VE, P-β-CAR, E-SOD, E-CAT and E-GSH-Px descended (P < 0. 01 ). The analysis of the stepwise regression and correlation indicated that the correlation of the course with P-NO, P-VE and P-β-CAR values was the closest. Compared with the preoperative patients, the average values of PNO, P-LPO and E-LPO were significantly decreased (P < 0.01 ) and the average values of PVC, E-SOD, E-CAT and E-GSH-Px in postoperative patients increased ( P < 0.01) in postoperative patients. But there was no significant difference in the average values of P-VE, P-W-CAR preoperative and postoperative patients. CONCLUSION Chronic cholecystitis could induce the increase of nitric oxide, oxidation, peroxidation and lipoperoxidation.

Therapeutic efficacy of high-dose vitamin C on acute pancreatitis and its potential mechanisms

AIM: To observe the therapeutic efficacy of high-dose Vitamin C 0/it. C) on acute pancreaUtis (AP), and to explore its potential mechanisms. METHODS: Eghty-four AP patients were divided into treatment group and control group, 40 healthy subjects were taken as a normal group, In the treatment group, Vit. C (10 g/day) was given intravenously for 5 days, whereas in the control group, Vit. C (1 g/day) was given intravenously for 5 days. Symptoms, physical signs, duration of hospitalization, complications and mortality rate were monitored. Meanwhile, serum amylase, urine amylase and leukocyte counts were also determined. The concentration of plasma vitamin C (P-VC), plasma lipid peroxide (P-LPO), plasma vitamin E (P-VE), plasma β-carotene (P-β-CAR), whole blood glutathione (WB-GSH) and the activity of erythrocyte surperoxide dimutase (E-SOD) and erythrocyte catalase (E-CAT) as well as T lymphocyte phenotype were measured by spectrophotometry in the normal group and before and after treatment with Vit. C in the treatment and the control group. RESULTS: Compared with the normal group, the average values of P-VC, P-VE, P-β-CAR, WB-GSH and the activity of E-SOD and E-CAT in AP patients were significantly decreased and the average value of P-LPO was significantly increased, especially in severe acute pancreatitis (SAP) patients (P&lt;0.05. P-VC, P=0.045; P-VE, P=0.038; P=0.041;P-β-CAR, P=0.046; WB-GSH, P=0.039; E-SOD, P=0.019;E-CAT, P=0.020; P-LPO, P=0.038). Compared with the normal group, CD3 and CD4 positive cells in AP patients were significantly decreased. The ratio of CD4/CD8 and CD4 positive cells were decreased, especially in SAP patients (P&lt;0.05. CD4/CDs, P=0.041; CD4, P =0.019). Fever and vomiting disappeared, and leukocyte counts and amylase in urine and blood become normal quicker in the treatment group than in the control group. Moreover, patients in treatment group also had a higher cure rate, a lower complication rate and a shorter in-ward days compared with those in he control group. After treatment, the average value of P-VC was significantly higher and the values of SIL-2R, TNF-α, IL-6 and IL-8 were significantly lower in the treatment group than in the control group (P&lt;0.05 P-VC, P=0.045; SIL-2R, P=0.012; TNF-α, P=0.030; IL-6, P=0.015,and IL-8, P=0.043). In addition, the ratio of CDJCD8 and CD4 positive cells in the patients of treatment group were significantly higher than that of the control group after treatment (P&lt;0.05. CD4/CDs, P =0.039; CD4, P=0.024). CONCLUSION: High-dose vitamin C has therapeutic efficacy on acute pancreatitis. The potential mechanisms include promotion of anti-oxidizing ability of AP patients, blocking of lipid peroxidation in the plasma and improvement of cellular immune function.

动脉瘤性蛛网膜下腔出血患者血液及脑脊液中内皮素和一氧化氮含量变化

目的探讨动脉瘤性蛛网膜下腔出血（ＳＡＨ）患者血液及脑脊液中内皮素（ＥＴ）和一氧化氮（ＮＯ）的含量与脑血管痉挛（ＣＶＳ）及临床病情的关系。方法采用放射免疫方法测定血液和脑脊液中ＥＴ含量;采用硝酸还原酶法测定血液和脑脊液中ＮＯ的代谢产物ＮＯ－ｘ（ＮＯ－２和ＮＯ－３）含量。结果ＳＡＨ后血液和脑脊液中ＥＴ含量增高（Ｐ＜００５）,且重症组高于轻症组（Ｐ＜００５）;而ＳＡＨ后血液和脑脊液中ＮＯ含量则下降（Ｐ＜００５）,重症组下降更加明显（Ｐ＜００５）。结论提示ＳＡＨ后脑血管痉挛和迟发性脑缺血可能系ＥＴ升高和ＮＯ下降使大脑动脉持续收缩所致,且临床症状的严重程度与ＥＴ增高和ＮＯ下降的程度密切相关。本实验结果支持ＳＡＨ后ＣＶＳ发生机制中ＥＴ与ＮＯ动态平衡破坏学说。
