OBJECTIVETo investigate the influence of continuous renal replacement therapy (CRRT) on the plasma levels of endotoxin and cytokines in severely burned patients with sepsis.

METHODSTen burn patients who received CRRT and another 10 without CRRT were investigated in terms of the changes in their plasma concentrations of endotoxin and some cytokines (TNFalpha, IL-1beta, IL-6, IL-8).

RESULTSThe plasma concentrations of endotoxin and all the cytokines (TNFalpha, IL-1beta, IL-6, IL-8) after CRRT treatment were significantly lower than those before the treatment (P < 0.01), and the plasma levels of the above factors at all the time points after CRRT treatment than those in patients were evidently lower by routine treatment (P < 0.05 - 0.01).

CONCLUSIONCRRT treatment could effectively lower the plasma levels of endotoxin and some cytokines (TNFalpha, IL-1beta, IL-6, IL-8).

This work was aimed to investigate the effect of quinacrine on peripheral granulocytes and lymphocytes, interleukin 1 (IL-1) and interleukin 6 (IL-6) in peripheral blood serum of inflammatory reaction induced by microwave irradiation, and observe the protective effect of quinacrine against microwave irradiation injury. BALB/c mice were suffered from microwave irradiation with the total intensity of 50 mW/cm(2) for 30 minutes, at 1 hour before irradiation quinacrine (12.6 mg/kg or 50.4 mg/kg) was orally administrated. Mice received same volume of water for injection instead of quinacrine were named as microwave irradiation group (MR group), and mice received no microwave irradiation but stayed in microwave irradiation environment also for 30 min were set as control. After microwave irradiation, mice were sacrificed and peripheral blood cells were analyzed with cytoanalyzer, and mice serum interleukin-1β, interleukin-6 were detected by radioimmunoassay. The results showed that microwave irradiation increased the count of peripheral granulocytes and lymphocyte along with prolongation of time, while the increase of these cells in mice administrated quinacrine was markedly delayed. The level of IL-1β in serum of mice was significantly increased after 1 day of microwave irradiation (50 mW/cm(2)), and recovered to normal level after 7 days. The 2 concentrations of quinacrine (12.6 mg/kg, 50.4 mg/kg) could suppress level of IL-1β in serum induced by microwave irradiation. The level of IL-6 in serum of mice was gradually increased after microwave irradiation with intensity of 50 mW/cm(2) for 7 days, but quinacrine administration could delay the rise of IL-6 level, specially within time of 2 days. It is concluded that the quinacrine administration can delay the increase of peripheral granulocytes and lymphocytes inducted by microwave irradiation, and may partially suppress the rise of IL-1β and IL-6 in serum. The results of this study suggest that the quinacrine can provide some protective effect against microwave irradiation injury.

OBJECTIVETo observe the seasonal changes in serum levels of interleukin-1 beta (IL-1β), interleukin-6 (IL-6) and melatonin (MT) in Bizheng rat model, and explore the relationship between MT and the pathogenesis of rheumatoid arthritis.

METHODSOne hundred and sixty Sprague-Dawley rats were randomly divided into four groups in summer (n=80) and winter (n=80) respectively: normal group, collagen-induced arthritis (CIA) model group, operation group, and sham-operation group (n=20 in each group). The CIA model group was injected with collagen emulsion at the base of the tail to induce arthritis. The rats in the operation group received pineal gland resection, and 7 days after the first operation, underwent testectomy or oophorectomy. The rats in the sham-operation group were operated to ligature the sagittal sinus, without extracting the pineal gland. After the operations, the operation group and the sham-operation group both were immunized as the CIA group was. The serum levels of IL-1β, IL-6 and MT in different groups were measured by radioimmunoassay.

RESULTSCompared with the normal group, the serum levels of IL-1β and IL-6 increased in the CIA model, operation, and sham-operation groups both in summer and in winter (IL-1β in summer, P=0.008, P<0.01, P=0.012; IL-1β in winter, P=0.019, P<0.01, P=0.027; IL-6 in summer, P=0.028, P<0.01, P=0.024; IL-6 in winter, P=0.006, P<0.01, P=0.008). In the operation group, the serum levels of IL-1β and IL-6 in winter were higher than in summer, but with no statistically significant differences (P=0.844, 0.679). Compared with the normal group, the serum level of MT significantly increased in summer and winter in both the CIA model group (P=0.002, 0.008) and the sham-operation group (P=0.003, 0.007), while significantly decreased in the operation group (P=0.023, 0.003). There was no significant difference in MT level in the operation group between summer and winter (P=0.947).

CONCLUSIONSThe increase of serum levels of IL-1β and IL-6 may exacerbate the inflammatory reaction and cause a more severe condition in the rheumatoid arthritis. The concentrations of IL-1β, IL-6, and MT correspond with the change of seasons, confirming that there are connections between nature and human body.

OBJECTIVETo compare the systemic and local near atherosclerosis lesion levels of pro-inflammatory factor interleukin-1β (IL-1β) and anti-inflammatory factor IL-10 in patients with coronary artery disease (CAD).

METHODSPlasma samples were collected from 30 individuals without angiographical coronary artery stenosis (control group), 90 patients with CAD (stable angina pectoris, SA, n = 30, unstable angina pectoris/non-ST-segment elevation myocardial infarction, UA/NSTEMI, n = 30 and ST-segment elevation myocardial infarction, STEMI, n = 30). During diagnostic coronary angiography or interventional procedures, systemic samples were obtained from aorta root in all patients (n = 120), local samples from distal of the coronary lesion in patients with CAD (n = 90), and samples from coronary sinus of 14 patients with STEMI. IL-1β and IL-10 were determined by ELISA method.

RESULTSThe result showed systemic levels of IL-1β were lg(-1) (0.97 ± 0.42), lg(-1) (0.98 ± 0.43), lg(-1) (1.21 ± 0.42), lg(-1) (1.30 ± 0.43) ng/L in the control, SA, UA/NSTEMI and STEMI groups, were significantly higher in UA/NSTEMI and STEMI groups compared with the control group (P < 0.05, P < 0.01); systemic IL-10 levels were lg(-1) (0.77 ± 0.29), lg(-1) (0.73 ± 0.45), lg(-1) (0.75 ± 0.35), lg(-1) (1.14 ± 0.36) ng/L in the four groups and was significantly higher in STEMI group than the control group (P < 0.01). The local concentration of IL-1β and IL-10 were similar as the systemic levels in SA group [lg(-1) (0.98 ± 0.41), lg(-1) (0.67 ± 0.47) ng/L], local IL-1β [lg(-1) (1.22 ± 0.48) ng/L] was similar while local IL-10 [lg(-1) (0.89 ± 0.46) ng/L] was significantly higher than the systemic levels in UA/NSTEMI group. The local levels of IL-1β and IL-10 [lg(-1) (1.45 ± 0.45), lg(-1) (1.35 ± 0.31) ng/L] were both significantly higher than the systemic levels in STEMI group (all P < 0.01). The IL-1β levels of systemic, local and coronary sinus in STEMI patients with acute totally occluded left coronary artery [lg(-1) (1.47 ± 0.37), lg(-1) (1.65 ± 0.34), lg(-1) (1.53 ± 0.35)ng/L] and the IL-10 levels [lg(-1) (1.06 ± 0.48), lg(-1) (1.34 ± 0.39), lg(-1) (1.34 ± 0.23) ng/L] were similar. The level of IL-1β in coronary sinus was significantly lower than in culprit lesion (P < 0.05) while IL-10 levels were similar at these two sites (P > 0.05).

CONCLUSIONThe systemic level of pro-inflammatory marker IL-1β and anti-inflammatory marker IL-10 could not reliably reflect the local inflammatory status near the atherosclerosis plaque locations.

Some variables can influence the efficiency of leukocyte removal filter for red cell concentrates. We performed this study to evaluate whether the filtration efficiency for platelet concentrates(PCs) can be influenced by bedside filter(PXL8K, Pall Corporation, USA) used, platelet storage time and transient stopping of platelet agitation, and to measure the amount of cytokines released from donor leukocytes in PCs during the storage time. In addition, we examined the effect of leukocyte reduction by filtration before the storage of PCs on the subsequent generation of cytokines. Any of the above mentioned variables did not make significant differences. From day 1 to day 5, there were significant increases in IL-1 beta (<1 vs. 8.6 pg/mL, p<0.05), IL-8 (<10 vs. 455.3 pg/mL, p<0.05) and TNF-alpha (<4 vs. 16.6 pg/mL, p<0.05) in unflltered PCs, whereas no increased revels of cytokines were found in the cases of prestorage filtration.

OBJECTIVETo explore the effect of acupuncture-anesthetic composite anesthesia (AACA) on the incidence of postoperative cognitive dysfunction (POCD) and changes of TNF-alpha, IL-1beta, and IL-6 in elderly patients.

METHODSTotally 83 patients undergoing surgical resection of gastrointestinal tumor were randomly assigned to the simple anesthesia group (A group, 41 cases) and the AACA group (B group, 42 cases). Patients in Group A received endotracheal general anesthesia. Those in Group B were induced by acupuncture anesthesia for 30 min by needling at Baihui (DU20), Neiguan (PC6), Zusanli (ST36). The electro-acupuncture (EA) apparatus was connected after arrival of qi, with the wave pattern of density 2/100 Hz. The stimulus intensity was set by patients' tolerance, with the peak current of 5 mA. Then the endotracheal general anesthesia was performed and the EA lasted till the end of the surgery. The cognitive function of all patients was assessed before operation and at day 3 after operation using mini-mental state examination (MMSE). POCD was confirmed if with one or more decreased stand- ard. The peripheral venous blood was collected before anesthesia induction (TO), immediately at the end of surgery (T1), 24 h after operation (T2), and 48 h after operation (T3), and serum concentrations of IL-1beta, IL-6, and TNF-alpha were correspondingly measured using ELISA.

RESULTSThe postoperative anesthesia awakening time was shorter in Group B than in Group A [(20.37 +/- 6.09) min vs (29.24 +/- 7.48) min, P < 0.05]. The remifentanil dose used during the operation was less in Group B than in Group A (P < 0.05). The incidence of POCD at day 3 was lower in Group B than in Group A [10/41 (23.8%) vs 15/42 (36.5%), P < 0.05]. The concentrations of IL-1beta, IL-6, and TNF-alpha at T1-T3 were higher than those at TO in the two groups (P < 0.05). The increment of TNF-alpha and IL-1beta was less in Group B than in Group A (P < 0.05). CONCLUSION AACA could reduce the incidence of POCD and inhibit postoperative release of TNF-alpha, IL-1beta, and IL-6 in elderly patients undergoing colorectal cancer resection.

OBJECTIVETo investigate the effects of Modified Sanhuang Decoction (, MSD) enema on the serum tumor necrosis factor alpha (TNF-α) and colonic mucosa interleukin-1β (IL-1β), interleukin-6 (IL-6) levels in experimental ulcerative colitis (UC) rats.

METHODSForty-five male Wistar rats were randomly divided into 4 groups: normal group (n=12), model group (n=11), salazosulfapyridine (SASP) group (n=11) and MSD group (n=11). The UC model was induced by 2,4,6-trinitrobenzene sulfonic acid (TNBS)/ethanol solution. Rats in the normal group and model group were clystered with 0.9% normal saline, while in the SASP group and MSD group were clystered with SASP and MSD enema, respectively. After drug administration (10 mL/kg body weight, for 7 days), colonic gross changes and colonic mucosa histology were observed, serum TNF-α and colonic mucosa IL-1β, IL-6 levels were tested by enzyme linked immunosorbent assay and radioimmunoassay, respectively.

RESULTSAs compared with the normal group, the experimental UC rats, the colonic mucosal damage index scores (CMDIs), histopathological scores (HS) and the serum TNF-α and colonic mucosa IL-1β, IL-6 levels significantly increased (P<0.05 or P<0.01). In the MSD and SASP groups, the ulcer area significantly reduced, and edema disappeared. The CMDIs, HS, the serum TNF-α and colonic mucosa IL-1β, IL-6 levels in the MSD and SASP groups significantly decreased (P<0.05 or P<0.01) compared with the model group. The CMDIs in the MSD group were lower than that in the SASP group (P<0.05), but there were no significant differences in HS, serum TNF-α or colonic mucosa IL-1β, IL-6 levels between the MSD and SASP groups.

CONCLUSIONMSD enema can improve colonic mucosa impairment and decrease serum TNF-α and colonic mucosa IL-1β, IL-6 levels in experimental UC.

OBJECTIVETo observe the change of cytokine interleukin IL-1 beta, IL-6, IL-10, tumor necrosis factor-alpha (TNF-alpha) occurred in acute paraquat (PQ) poisoning rats and to investigate the mechanism of acute lung injury caused by paraquat (PQ) poisoning.

METHODSAll 72 healthy adult Wistar rats were random assigned into normal control groups, paraquat high dose group (120 mg/kg), paraquat middle dose (60 mg/kg) group, paraquat low dose group (30 mg/kg). Three observing periods of time included 8, 24, 72 h and the standards of TNF-alpha, IL-1 beta, IL-6, IL-10 were determined.

RESULTSEvery index of the PQ group was significantly higher than that in the NS group at the same period of time (P<0.05 or P<0.01). In the 72 h group, the high dose group was significantly higher than the middle and low dose group (P<0.05), and there was no significantly difference between the middle and low dose group (P>0.05). For the comparison of index in the same dose group, the group of 72 h was much higher than 8 h group and 24 h group (P<0.05), and there was no difference between the 8h group and 24 h group (P>0.05).

CONCLUSIONThe cytokine may play an important role in paraquat-induced acute lung tissue injury.
