Objective To investigate the effects of ulinastatin pretreatment on oxidative stress response and hepatocyte growth factor (HGF) after hepatectomy in rats.Methods One hundred and twelve pathogen-free male Sprague-Dawley rats,aged 3 months,weighing 230-280 g,were randomly divided into 2 groups (n=56 each): group hepatectomy (group H) and group ulinastatin pretreatment (group U).Left and median lobe resection was performed and then liver ischemia was induced by blood flow occlusion of right and caudate lobes for 30 min,followed by perfusion in both groups.Ulinastatin 50 000 U/kg was injected intravenously at 5 min before occlusion in group U.Eight rats in each group were chosen and the blood samples were taken from the inferior vena cava for measurement of serum ALT and AST activities and HGF concentration before ischemia and at 1,6,12,24and 48 h of reperfusion.Then the right lobe were removed for determination of apoptosis,SOD and myeloperoxidase (MPO) activities,MDA content,expression of proliferating cell nuclear antigen (PCNA) and liver regeneration.Apoptotic index was calculated.Another 8 rats in each group were chosen and the 7 day survival rate was recorded.Results Compared with group H,the levels of ALT,AST,MPO aud MDA and apoptotic index were significantly decreased,and the levels of HGF and SOD,PCNA expression and liver regeneration were significantly increased at different time points in group U (P ＜ 0.05).There was no significant difference in 7 day survival rate between group H and group U (P＞ 0.05).Conclusion Ulinastatin pretreatment can strengthen liver regeneration after hepatectomy in rats,the underlying mechanism may be related to inhibition of oxidative stress response and increase in HGF production.

Through comparative study on Naotaifang containing serum and plasma proteomics (peptide), this article revealed differential proteins (peptides) in the Naotaifang. The characteristics of differential proteins were identified with mass spectrometry. It provides scientific evidences for the pharmacodynamic material basis and Chinese herbal medicine plasma pharmacological method development in the exploration of Naotaifang. A total of 20 healthy adult SD rats were randomly divided into the control group, Naotaifang treatment group according to their weights. Ten rats in each group. Intragastric administration of medication was given for seven consecutive days. Before surgery, rats were fed with water but without food. One hour after the last drug administration, 10% chloral hydrate was injected for intraperitoneal anesthesia. Blood was taken through the common carotid artery. Serum and plasma samples were made after blood was taken from each rat. Serum and plasma samples of five rats were randomly selected from each group. And the two-dimensional electrophoresis (2-DE) technique was used in the comparative study of serum pro-teomics (peptide). The 300 DPI scanning and PDQuest 7.3.0 were used in the analysis. The ESI-MS/MS was used to identify important differences in proteins and screen characteristic serum and plasma protein. The results showed that 20 differential proteins of 5 plasma samples were identified. There were 15 types of proteins expressing up-regulation and 5 types expressing down-regulation. Comparative analysis on the 2-DE gel pictures of Naotaifang containing serum, 19 differential proteins of 5 plasma samples were identified, among which 15 types of proteins express up-regulation and 4 down-regulation. Comparative analysis on the 2-DE gel pictures of Naotaifang containing serum and Naotaifang containing plasma showed that 24 differential proteins of 5 plasma samples were identified, among which 9 types of proteins express up-regulation and 15 down-regulation. The highly expressed proteins were selected to MALDI-TOF-MS between Naotaifang containing serum and Naotaifang containing plasma. There were six successful-ly identified proteins, which were inter-alpha trypsin inhibitor, heavy chain 3, group-specific component, comple-ment factor B, Receptor Complexed with A Heterodimeric Fc, isoform CRA-d, Transferrin. It was concluded that protein with obvious changes in the Naotaifang containing serum and plasma may be related with fibrinolysis and an-ticoagulant. These proteins are involved in angiogenesis, inflammation and other pathological regulations of physiolog-ical processes. They are of great significance in the study of effective target and its signal transduction pathway of Naotaifang.

Objective To investigate the protective effect of propofol pretreatment against hepatic ischemia-reperfusion injury and oxidative stress in rats and the mechanism of the role of GSK-3 β.Methods Sixty SD rats were randomly divided into four groups:sham operation group (S group),ischemia-reperfusion group (I-R group),propofol pretreatment group (P group),TDZD-8 pretreatment group (T group).The hepatic ischemia-reperfusion rat models were established by the method of Nauta.Rats were subjected to 30-min,60-min and 90-min 70％ warm ischemia of liver followed by reperfusion for 120 min,respectively.Propofol (12 mg/kg · h) was injected via femoral vein 30 min before ischemia till the end of reperfusion in P group and TDZD-8 (1 mg/kg) were injected via femoral vein 20 min before ischemia in T group.The animals were killed at 120 min after reperfusion.Blood samples and the liver tissue were obtained.The levels of alanine aminotransferase (ALT),aspartate aminotransferase (AST),lactate dehydrogenase (LDH),malondialdehyde (MDA) and superoxide dismutase (SOD) were analyzed.Liver morphological changes were observed using optical microscopy.p-GSK-3β Ser9 and total GSK-3 β expression was determined by Western blot.Results Compared with S group,AST,ALT,LDH and MDA level was increased,SOD level was reduced,and p-GSK-3 β Ser9 expression was significantly reduced in I-R group.Compared with I-R group,the content of AST,ALT,LDH and MDA was reduced significantly,SOD increased significantly,and the content of p-GSK-3β Ser9 increased significantly in P group and T group.There were no significant differences between P group and T group.The hematoxylin-eosin staining of hepatic tissues revealed in I-R group had severe structural damage and periportal inflammatory cells infiltrated,hepatocyte necrosis and sinusoidal congestion.In P group and T group,liver tissues had normal structure,less cell death,edema and inflammatory cell infiltration.Conclusions Propofol can significantly reduce hepatic ischemia reperfusion injury by reducing oxidative stress and lipid hydroperoxides.This protective effect of Propofol may be associated with the inhibition of GSK-3 β by GSK-3 β Ser9 phosphorylation.

Objective:To investigate the perfection and improvement of the execution of integrative medicine therapy in severe tetanus therapy, to successfully control tetanus severe spasms, autonomic dysfunction and prevent lethal side-effect of prolong and high-dosage sedative-muscle-relaxant therapy, resulted in significant reduction of mortality of tetanus.Methods:Symptoms, treatments and outcome of tetanus patients admitted to Peking University Third Hospital from 1965 to 2020 were reviewed. Patients were classified with Ablett classification. The cases of Ablett grade Ⅲ and Ⅳ were severe tetanus. The patients were divided into two groups according to whether they were treated together with traditional Chinese medicine (TCM) simultaneously during the standard tetanus treatment; the patients in the TCM group were divided into the tetanus TCM medication group and the non tetanus TCM medication group according to the medicine provided whether was in accord with the conventional tetanus TCM prescriptions. The mortality of each group was calculated. In addition, one survived and one deceased case with severe convulsion, autonomic nerve dysfunction (Ablett grade Ⅳ) were selected, combined with the treatment methods and curative effects, the types, use methods and outcomes of Chinese and Western medicine were analyzed.Results:The 46 tetanus cases were treated with Western medicine. Twenty-two of them, TCM were applied. Fifteen of the 22 cases took the TCM prescription which was accord with the conventional tetanus prescription. The mortality of the 46 cases was 21.7% (10/46). The number of non-TCM group was 24 cases, with mortality of 20.8% (5/24); 1 case was Ablett Ⅱ, 1 was Ablett Ⅲ and 3 were Ablett Ⅳ. The number of the TCM group was 22 cases, with mortality of 22.7% (5/22), 2 cases were Ablett Ⅲ, 3 were Ablett Ⅳ. The TCM prescription of these 5 deceased cases was not directed towards tetanus. The tetanus TCM medication group was 15 cases, with no mortality. Case analyses: case 1 was intubated because of severe spasms. Autonomic dysfunction occurred on the 8th day after admission. Esmolol with increasing the dosage of the sedatives and muscle relaxant, was not effective. Tetanus TCM was applied after 2 days of autonomic dysfunction happened. Autonomic dysfunction was then under controlled on the 2nd day post-TCM. She was recovery and discharged after 4 weeks. Case 2, also was intubated because of severe spasms. Autonomic dysfunction happened on the 3rd day after admission, and failed to be controlled by large-dose sedatives, muscle relaxant, and Esmolol. After 8 days of persistent autonomic dysfunction, tetanus TCM was applied and autonomic dysfunction was under controlled on the 2nd day post-TCM administration. Large dosage of muscle-relaxant was applied continuously. After 5 days' administration of TCM, the TCM was withdrew. One day after the withdrawal of TCM, respiratory and cardiac arrest happened because of the diffused bronchiole obstruction with pulmonary secretions loading.Conclusion:Based on the precise and real-time diagnosis of the state of the disease, integrative medicine therapy with an overall analysis tetanus TCM prescription, is the key of declining tetanus mortality.
