ABSTRACT
Objective To study the therapeutic effects of omeprazoie in high-dose given by continuous intravenous infusion in the treatment of stress-related mucosal injury of G-I tract in intensive care patients.Method Totally 98 intensive care patients with stress-related mucosal injury(SRMI)were enrolled from August 2006 to October 2008 Department in Intensive Care Unit(ICU)of the Provincial Hospital Affiliated to Shandong University.All the patients were randomly divided into high-dose omeprazoie group(group A)and control group(group B).In group A,omeprazoie was administrated in loading dose of 80 mg Ⅰ.Ⅴ.in 5 minutes followed by maintenance dose of 8.0 mg/h intravenous infusion for 72 hours,while in group B,omeprazoie was given in dose of 40mg/8h intravenous infusion for 72 hours.The pH value of gastric juice was determined by German Roche pH test paper every 2 to 8 hours in the patients of both groups.The coffee like or red juice in the gastrointestine decompressor was observed.At the same time,hemoglobin(HB)was detected by Automatic blood cell analyzer Sysmex XE-2100,blood urea nitrogen(BUN)was determined by Automatic Analyzer Au5400,and buffer excess(BE)was checked by GEM Premie arterial blood gas analyzer in all patients.Data were expressed as mean ± standard deviation(x-± s)and the analysis of variance was done with SPSS 12.0 software.Comparison of mean value between two groups was conducted with t-test and the ratio was calculated by using chi-square test(X2 test).The change was considered as statistically significant if P value was less than 0.05.Results Four,eight,and 24 hours after treatment with omeprazole,the pH values in patients of group A were higher than those in patients of group B(four hous:6.63 ±0.62 vs.3.14 ±0.26,P＜0.01;eight hours and 24 hours:P＜0.05 or P＜0.01).At 8 hours and 24 hours after treatment,the HB was higher,BUN and BE were lower in group A than those in group B(P＜0.03 or P＜0.01).The total rate of hemostasis of upper G-I tract bleeding in group A was higher than that in group B(95.35%vs.78.19%,P＜0.05).Conclusions For treating the intensive care patients with SRMI,the continues intravenous infusion of omeprazole inhigh dose is superior to conventional dosage.
ABSTRACT
Objective To observe the clinical efficacy of ulinastatin(UT) conjoined to high flow continuous blood purification( CBP) in the critical patients with multiple organ dysfunction syndrome(MODS). To evaluate the therapeutic potential of UT and CBP in systemic inflammatory response syndrome (SIRS) , severe sepsis( SS) , acute lung injury (ALI) and acute respiratory distress syndrome (ARDS). Method A total of 122 cases of emergency and critical patients with a score of more than 15 counted up from APACHE H (acute physiology and chronic health evaluation 11 ) were randomly divided into Ulinastatin treatment group (UT group, n = 35) .continuous blood pu-rification(CBP group, n = 31),UT plus CBP (combine group, n = 30) and routine treatment group (control group, n =26). Routine treatment was given to patients of all groups, and patients of UT group had Ulinastatin 0.4 MIU given intravenously every 8 hours for 7 days in addition. Patients of CBP group were managed with continuous blood purification round the clock for 7 days and those of combine group were treated with UT plus CBP for 7 days.The efficacy of the treatment in four groups was assessed,and serum high sensivity reactive protein(hs-CRP) and IL-6 levels were measured on admission and comparison was made between values of biomarkers taken before and 1 d,3 d,and 7 d after treatment in four groups. The changes in WBCs,arterial gas analysis and the oxygena-tion index PaO2/FiO2 were checked, and at the same time, the APACHE II values and the incidence of MODS were compared within four groups. Results (1)One, three and seven days after treatment the plasma hs-CRP and IL-6 levels in UT and CBP groups were reduced significantly more than those in control group ( P < 0. 05), and in combine groups those were more dramatically lowered ( P < 0.05, P < 0.01). Before treatment there was no significance diffience in those values between groups, and there was on diffience in those values between 3 rd day and 7 th day after treatment ( P > 0.05). (2) The 1 st,3 rd and 7 th day after treatment the arterial gas PaO2/FiO2 index in UT and CBP groups was improved more than that in control group ( P < 0.05) , and it in combine group was most significant improved (P < 0.05,P < 0.01). The ALT and creatinine were lower than those in control group ( P < 0.05), and there were no significant differences in ALT and creatinine between groups before treatment (P > 0.05). (3) The 1 st,3 rd and 7th day afer treatment,the APACHE II values in UT and CBP groups were decreased more than those in control group ( P < 0. 05) , and therefore, the incidence of MODS was lower ( P < 0.05). Conclusions Ulinastatin could significantly inhibit the production of inflammatory cytokines and CBP could effectively eliminate inflammatory factors from blood, and the combination of these two approaches produce a more effective therapeutic potential for preventing MODS development.
ABSTRACT
BACKGROUND:Idiopathic interstitial pneumonia is of poor response to treatment. Glucocorticoids are the first medicine for the treatment, however there is only 30% of the patients who are responded. Traditional Chinese drugs (TCD) have been researched hot point for prevention and treatment of pulmonary fibrosis. Many TCD have been used clinically, and with a certain therapeutic effect. Transforming growth factor-β1 and tumor necrosis factor-α are the considerable cytokines to cause pulmonary fibrosis, inhibition of their expression, therefore, may be effective to pulmonary fibrosis.OBJECTIVE: To investigate the interventional effect of qidan granule on pulmonary fibrosis in rats induced by bleomycin A5 and the influence on the expressions of transforming growth factor-β1 and tumor necrosis factorα, and also to compare with those of hydrocortisone.DESIGN:A randomized and interval grouping design.SETTING:Department of Respiratory Medicine, Shandong Provincial Hospital, Shandong University.MATERIALS:The experiment was conducted from May 2003 to March 2004 at Pathological Laboratory of Shandong Provincial Academy of Medical Science. Totally 105 SD male rats, were at random divided into 4groups: normal control group (n= 15 ), model group, qidan group and hydrocortisone group, with 30 rats in each group. Each group was subdivided as7-day, 14-day and 28-day group, with 5 rats in each normal group, and 10in each other groups.METHODS: [1] Model establishment: A perfusion was intrabronchially performed, of 0.25 mL normal saline for rats in normal control group, and of bleomycin A5 0.25 mL ( 5 mg/kg,4 g/L) for rats in other 3 groups, to set up the models of pulmonary fibrosis. [2]Administration: Next day to the beginning of modeling qidan granule (consisting of Radix Astragali seu Hedysari, Radix Salviae Miltiorrhizae, Rhizoma Ligustici Chuanxiong and so on, 3 125 mg/kg) was intragastrically given per day for rats in qidan group, hydrocortisone (25 mg/kg) was intraperitoneally given per day for rats in hydrocortisone group, and normal saline (2 mL/rat) was intragastrically given per day for rats in normal and model groups.[3] Observation indexes: The rats in each group were on the day 7, day 14 and day 28 put to death under the anesthesia, then the lung tissue was taken, stained with hematoxyline-eosin stain for pathological observation of lung tissue. The expressions of transforming growth factor-β1 and tumor necrosis factor-α were detected by immunohistochemistry.MAIN OUTCOME MEASURES:Pathological observation of lung tissue,and the expressions of transforming growth factor-β1 and tumor necrosis factor-α at different time points of rats in each group.RESULTS:Totally 100 rats entered the final result analysis.[1]Pathological observation of lung tissue: In the normal group the structure was normal, in the model group there were alveolitis on the day 7, deterioration of alveolitis on the day 14, and extensive fibrosis on the day 28; the degrees of alveolitis and fibrosis in the qidan group were slighter than those in the model group, and there was normal structure of alveoli; and in the hydrocortisone group the alveolitis on the day 7 and 14 was slighter than that in the model group, but there was no significant difference of fibrosis compared with the model group.[2] Expression of transforming growth factor-β1:In the model group the expression was highest on the day 28 and obviously higher than that in the normal group (3.6±0.4,1.2±0.4,P ＜ 0.01 ); the expression in the qidan group and hydrocortisone group was obviously lower than that in the model group(1.7±0.5,2.5±0.4,P ＜ 0.01), and the expression in the qidan group was lower than that in the hydrocortisone group (P＜ 0.01 ). [3]Expression of tumor necrosis factor-α: In the model group at different time points the expression was continuously increased, the expression in the qidan group and hydrocortisone group was obviously lower than that in the model group(P ＜ 0.05 or P ＜ 0.01), and the expression in the qidan group was lower than that in the hydrocortisone group ( P ＜ 0.01).CONCLUSION: Qidan granule can obviously reduce the extent of pulmonary fibrosis in rats induced by bleomycin A5, lower the expressions of transforming growth factor-β1 and tumor necrosis factor-α, and the effect was better than that of hydrocortisone.
