Chinese Journal of Pathophysiology 1986;0(04):-
The role of oxygen free radicals in multiple system organ failure (MSOF) was studied in rats produced by reticuloendothelial system blockade in addition to hemorrhagic shock. In MSOF animals blood reduced glutathione (GSH) elevated to 4.17?0.38 mg/g Hb at day 2, compared with baseline 2.67?0.09. Plasma glutathione peroxidase declined to 1.22?0.27 U/ml?min at day 1, and gradually increased at day 2 and day 3, but still lower than baseline 3.08?0.20. Blood superoxide dismutase (SOD) level was 182.6?27.1 at day 1, lower than baseline 249.5?72.4 ?g/g Hb. Plasma malondialdehyde (MDA) increased twice the normal level of 6.54?31 nmol/ml. Correlation analysis showed that lung index, plasma GPT and creatinine negatively correlated with the level of lung and liver homogenate SOD and kidney homogenate GSH, respectively.Results indicate that there are significant changes in the levels of blood and tissue antioxidants and lipid peroxides during MSOF. Organ failure appears to be correlated with the decrease in tissue antioxidation capacity.
2.The inhibitory effects of sinomeuine on complement - induced shape change and degranulation in rat neutrophils
Chinese Pharmacological Bulletin 1986;0(04):-
Complement activation induces polymorphonucleal neutrophilic leukocyte (PMN) aggregation in circulation causing microvascular occlusion. The activated PMNs release lysosome enzymes which damage the tissue. It might take an important part in shock and multiple organ failure. We pre-treated rat PMNs with sinomeuine, which was extracted and purified from the stem of Sinomeuium acufum Rehd et Wils. It was found to inhibit the morphological changes and lysosome enzymes release in PMNs activated with zymosanactivated plasma. With administration of sinomeuine PMNs remained a spherical shape, no apparent ruffling or cytoplasmic projection and less aggregation. Elastase and Nacetyl-?-D-glucosaminidase content in PMNs supernatant increased less.
3.Sinomeuine and sodium ferulate prevent complement-induced granulocyte aggregation
Chinese Journal of Pathophysiology 1986;0(01):-
Complement-induced polymorphonuclearcytes (PMN) aggregate in microvasculature of vital organs, produce microemboli, and block microcirculation blood flow. Activated PMN release oxygen free radicals, prostaglandins and proteases, in turn, damage endothelial and parenchyma cells. This is an important factor in pathogenesis of multiple system organ failure. We have found that Sinomeuine and Sodium Ferulate prevented PMN aggregation induced by activated complement. Adding the drugs into PMN suspension treated with cytochalasin B, the zymosan activated plasma, PMN aggregation was prevented. The changes of light transmission were smaller than those of control without drugs recorded with platelet aggregometer. The 50% of PMN aggregation inhibition with Sinomeuine was 0.76mg/ml (1.gmmol/L), and 0.82mg/ml (3.8mmol/L) with Sodium Ferulate.

BACKGROUND:Perioperative treatment of emergency liver transplantation for acute hepatic failure is extremely different from common liver transplantation, due to complex conditions, high risk, several complications, and high mortality. OBJECTIVE:To summarize the experience of emergency liver transplantation for acute hepatic failure during the perioperative period, and to increase the success rate in treatment of acute hepatic failure. METHODS:A retrospective analysis was undertaken on the clinical data of 38 cases undergone emergency liver transplantation for acute hepatic failure. There were 21 male and 17 female, who aged 15-69 years. Among them, 23 cases had hepatitis B virus (including 2 cases with hepatitis B and C virus), 7 cases had Wilsons disease, 3 cases had mushroom poisoning, 2 cases had unknown liver damage, 1 case had Tripterygium wilfordi poisoning, 1 case had decompensation after partial liver resection due to trauma, and 1 case had liver transplantation from corpse. RESULTS AND CONCLUSION:The survival time of the involve patients was 13-1 740 days, and the median survival time was 634 days. Perioperative survival rate was 76%, 1-year survival rate was 63%, and 2-year survival rate was 58%. During the perioperation nine cases died of brain edema and intracranial hypertension, renal failure, severe pulmonary infection, multiple organ failure, coagulation disorders (intracranial hemorrhage, upper digestive tract hemorrhage), acute respiratory distress syndrome and primary graft non-function. At present, emergency liver transplantation is stil the most effective way for acute liver failure. Hemorrhage, infection and rejection are the leading causes of the death. Each perioperative treatment is of great significance for the success of liver transplantation and long-term survival.

Ultrasonic microbubbles were used to open blood-brain barriers (BBB) with a reversed and limited behavior feature in the study, which could improve the brain-targeted delivery of anti-tumor drugs. The glioma rat model was prepared. Low-frequency ultrasound was combined with microbubbles to affect the permeability of BBB compared with the permeability of independently administered Evans blue (EB) crossing BBB. Time point and length of ultrasound were investigated whether they affect the permeability of BBB and the damage of brain tissue. The effect of the growth time of glioma on BBB permeability was explored. Only glioma had a very little impact on BBB permeability. However, ultrasonic microbubbles opened the BBB with the features of temporary, limited and reversed behavior and improved EB and magnetic resonance imaging contrast agent penetrating BBB. A length of 30 s ultrasound is appropriate for opening BBB and no damage of brain tissue. Drugs should be injected before ultrasound so that they enter into brain as BBB opening. Ultrasonic microbubbles can open BBB effectively and safely, which improve drugs penetrating BBB under proper time point and length.

Objective To investigate the association between nonalcoholic fatty liver disease (NAFLD) and metabolism or carotid intima-media thickness (CIMT) in Type 2 diabetic(T2DM). Methods According to the liver B-ultrasonography, a total of 321 T2DM patients were divided into two groups, with or without NAFLD. Metabolic indexes such as BMI, BP, blood glucose, blood lipid, uric acid ( UA ), insulin, C-peptipe,insulin resistance index(HOMA-IR) between the two groups were compared, and the relationships between alanine aminotransferase (ALT) and the above indexes were analyzed. Furthermore,the CIMT of the two groups were compared, and the relationships between NAFLD, ALT and CIMT were investigated by correlation and regression analysis. Results Compared with the group without NAFLD, the patients with NAFLD had higher level of BMI, triglyceride ( TG ), UA, fasting blood glucose ( FBG ), fasting insulin ( FIns ), fasting C peptide (FCP) ,HOMA-IR,and lower level of high density lipoprotein ( HDL-C ) significantly; BMI ( OR = 1.25, P <0. 001 ), TG ( OR = 1.74, P = 0. 008 ) and HOMA-IR ( OR = 2. 33, P = 0.010) were independent risk factors of NAFLD while H DL-C was independent protective factor; ALT was positively correlated with BMI (r = 0. 255, P <0. 001 ) ,TG(r =0. 156,P <0. 018) ,UA(r =0. 239,P <0. 001 ) ,FIns(r =0. 213,P =0. 001) ,FCP(r =0. 199,P <0. 003), HOMA-IR ( r = 0. 247, P < 0. 001 ) and negatively correlated with HDL-C ( r = - 0. 199, P =0. 002) ,and BMI (β =0. 456,P =0. 048) ,UA (β =0. 021 ,P =0. 025) and HOMA-IR(β =3.634 ,P =0. 004)were independent associated facrors. The difference of CIMT between the two groups didn't reach statistical significance, while mutiple regression analysis revealed that ALT was independently associated with CIMT(β =0. 002,P = 0. 013). Conclusion T2DM patients with NAFLD show more serious disorder of metabolism and insulin resistance. ALT is an independent risk factor of CIMT in T2DM patients.

AIM: To determine the evolutionary pattern of parenchymal cell apoptosis in multiple organs early after intestinal ischemia-reperfusion(I/R) and its induction mechanisms and the role of apoptosis in triggering SIRS/MODS. METHODS: An I/R model was reproduced by clipping and releasing the superior mesenteric artery in rats and mice. Flow cytometry, electron microscope, DNA agarose gel electrophoresis, TUNEL method, fluorescent and Gomori's silver-HE staining were used to detect apoptosis. Distribution features of apoptotic parenchymal cells in multiple organs were observed. Immunohistochemical staining of HSP 70 and Bcl-2 were performd to study the induction mechanisms of apoptosis.RESULTS and CONCLUSION: 1. Damage of the liver, lung, gut and kidney was appeared in early phase of I/R. The percentages of apoptosis in parenchyma organs increased progressively. The percentages of cell necrosis increased with the prolonged I/R duration. 2. Percentages of apoptosis were much higher near the central veins of liver lobules, in the outer medulla of the kidney, and the antimescenteric border of intestinal mucosal epithelium because of ischemia. 3. The expression of HSP 70 increased and Bcl-2 reduced in the areas mentioned above because of hypoperfusion. 4. Apoptosis of I/R hepatocytes, splenocytes and thymocytes was obviously increased after Kupffer cell blockage with GdCl3, showing the functional state of Kupffer cells may play an important role in SIRS/MODS.
