Objective To investigate the effect of oral fluid resuscitation on circulatory oxygen dynamic parameters in dogs with burn shock.Method Eighteen male Beagle dogs were surgically prepared for the cannulation of carotid cartery and jugular vein,subjected to flame injury 50%total body surface area(TBSA)with fullthick ness 24 hours later,and they then randomly divided into 3 equal groups.The oral fluid resuscitation group (OR group)was intragastrieally injected with infusion of glucose-electrolyte solution(GES)according to parkland formula 0.5h after burn with a dose of 4mL·kg-1·% TBSA-1.Intravenous (IV) GES resuscitation group (VR group)was intravenously injected with infusion of GES as the same dose as OR group,and no-fluid resuscitation (NR)group did not receive any treatment during the first 24 hotrs.In the second 24 hours,all dogs received Ⅳ fluid resuscitation.At the end of 72 hours of injury.the mortality in each group was recorded.The mean arterial arterial pressure(MAP),hematocrit(HCT)and blood lactic acid(LAC)were determined,and blood gas analysis was evaluated for oxygen delivery(DO2),oxygen consumption(VO2)and oxygen uptake(O2ext)before injury and 2,4,8,24,48 and 72 hours after injury.Results Burn injury resulted in a 77.1%decrease in MAP,and a 48.5% increase in HCT and 533.7%increase in LAC in NR group,followed by pngressively lowering of DO2,VO2 and Oext till all animals died with in 24 hours after burn.MAP and HCT levels oftwo resuscitation groups gradually returned to the pre-injury levels within 72 hours after burn,but the LAC levels sill remained significantly higher than the pte-injury levels(P＜0.01).The MAPs of OR group were higher at corresponding intervals within 24 hours post burn than those of NR group(P＜0.01),but they were lower than those of VR group(P＜0.01).The serum LAC in OR group was markedly lowered than that in NR group,but it was higher than that in VR group.Twenty-four hours after burn injury,the DO2 level in OR group showed no significant differences compared with that of the VR group,but the levels of the VO2 and Oext were still much lower than those of VR group (P＜0.01).At the end of 72 hours,3 dogs of NR group died and none of IV group died.Caadusions Oral fluid resuscitation improves oxygen dynamic,alleviates hyperlactacidemia and reduces the mortality of animals with severe burn shock.

Objective To study the expression and significance of miR-26a in intrahepatic cholangiocarcinoma.Methods The expression of miR-26a in 46 intrahepatic cholangiocarcinoma(ICC) tissues and peritumoral tissues was detected by quantitative real time polymerase chain reaction (qRT PCR).The intrahepatic eholangiocarcinoma cell line HCCC-9810 and RBE were transfected with miR 26a mimics and miR 26a inhibitors,respectively,by lipofectamine 2000.The growth curves were constructed by the CCK 8 method.The migration and invasion ability was demonstrated by wound healing and transwell assay.The cell cycle was analyzed by flow cytometry.The potential mechanism was illustrated by Western blotting.Results For the 46 ICC tissues and peritumoral tissues,miR 26a levels were significantly higher in the tumor tissues than in the peritumoral tissues (P＜0.05).Vascular invasion,TNM Ⅲ～Ⅳ stage and lymph node metastasis were significantly associated with high miR 26a expression levels (P＜0.05),but gender,age,tumor amounts,tumor encapsulation,tumor diameter and tumor differentiation showed no significant association (P＞0.05).Enhanced cell proliferation,migration and invasion ability,accelerated G0/G1 phase to S phase transition,activated AKT by PTEN suppression were observed in HCCC-9810 cells with up regulation of miR-26a.Conversely,cell proliferation,migration and invasion ability was inhibited,G0/G1 phase was blocked and AKT was restrained by PTEN increase wkh down regulation of miR-26a in RBE cells.PTEN mRNA in versely correlated with the miR-26a level (r=-0.8272,P＜0.01).Patients with a high miR-26a expression had significantly poorer overall survival (P＜0.05).A high miR 26a exprcssion,multiple tumors and lymph node metastasis were independent prognostic factors of overall survival (P＜0.01).Conclusion Overexpression of miR-26a in intrahepatic cholangiocarcinoma correlated with clinicopath ological features and overall survival,and it potentially promoted tumor proliferation and metastasis through the PTEN/AKT pathway.

BACKGROUND:In recent years, minimal y invasive percutaneous plate fixation has been a selectable method to repair fracture of lower limbs, especial y complex fracture of lower limbs. Its advantages are to reduce the damage to soft tissues, and do not destroy bone nutrient supply vessels. However, there is no unified criterion to select which method in the repair of distal tibial fractures. OBJECTIVE:To observe clinical effects of minimal y invasive percutaneous plate fixation versus open reduction and plate fixation in the repair of distal tibial fractures. METHODS:A total of 60 cases of distal tibial fractures treated with minimal y invasive percutaneous plate osteosynthesis (n=35) and open reduction and plate fixation (n=25) were selected. The time of surgery was identified by evaluating soft tissue. We should pay attention to the protection of soft tissue in surgery and reasonable fixation method should be selected. After fixation, we guided patients to do active early functional exercise. They were fol owed up and regularly received X-ray reexamination. Operation time, weight loading time, healing time and functional recovery were observed and the clinical therapeutic effects of the two methods were compared. RESULTS AND CONCLUSION:Al patients were fol owed-up after surgery. They were fol owed up for 3 to 15 months. No significant difference in healing time of type A fracture was detected between minimal y invasive percutaneous plate fixation and open reduction and plate fixation. The healing time of types B and C fracture was better in minimal y invasive percutaneous plate fixation group than in open reduction and plate fixation group. These results indicated that minimal y invasive percutaneous plate fixation in repair of tibial fractures, especial y distal complex tibial fractures, is an effective method. The healing rate of fracture was high, but postoperative complications were less.

Objective Yangqing Chenfei Formula - To investigate the effect of (YCF) on epithelial mesenchymal transition (EMT) Methods in lung tissues of silicosis model rats. Specific pathogen free adult male SD rats were randomly divided into control group, model group, tetrandrine group and YCF group, with eight rats in each group. The rats in the model group, tetrandrine group and YCF group were intratracheally injected with 1.00 mL of silica suspension with a mass concentration of 50.0 g/L, and the rats in the control group were given an equal volume of 0.9% sodium chloride solution. On the 15th day after modeling, the tetrandrine group was given tetrandrine at a dose of 27.0 mg/kg body weight, the YCF group was given YCF with a dose of 8.91 g/kg body weight, while both the control group and model group were given 2.00 mL 0.9% sodium chloride solution. Gavage wasperformed twice a day in the morning and evening for 14 days. On day 29 of the experiment, after evaluating the tidal volume, - functional residual volume (FRC) and vital capacity of rats in each group, lung tissues were collected, and hematoxylin eosin staining and Masson staining were performed to examine the histopathological changes, and the fibrosis score was evaluated. - - Hydroxyproline level was detected by colorimetry. The expression of type Ⅰ collagen (COL Ⅰ), type Ⅲ collagen (COL Ⅲ), - - - - - - E cadherin (E Cad), N cadherin (N Cad) and α smooth muscle actin (α SMA) protein was detected by immunohistochemistry. - The expression of epithelial cell adhesion molecule (EpCAM) and fibroblast specific protein 1 (FSP 1) was detected by Results immunofluorescence. The lung structure was intact and the alveolar structure was normal in the control group. The alveolar structure was destroyed, the alveolar wall was thickened, and cellular nodules were observed/n the model group. The lung tissue lesions of rats in the tetrandrine group and YCF group were reduced compared with that in the model group, and there was no difference in the degree of lesions between the two groups. The tidal volume, FRC and vital capacity of rats in model P< - P< group decreased (all 0.05), the relative expression of E Cad protein in lung tissue decreased ( 0.05), the fibrosis score and - - - - the level of hydroxyproline, the protein relative expression of COL Ⅰ, COL Ⅲ, N Cad and α SMA in lung tissue increased (all P< - 0.05), while the fluorescence intensity of EpCAM protein decreased, and that of FSP 1 protein increased compared with the P< control group. The tidal volume, FRC and vital capacity of rats in tetrandrine and YCF groups increased (all 0.05), the fibrosis - - - score and the level of hydroxyproline, the protein relative expression of COL Ⅰ, N Cad and α SMA in lung tissue decreased (all P< - P< 0.05), the relative expression of E Cad protein in lung tissues increased ( 0.05), while the EpCAM protein fluorescence - intensity increased and FSP 1 protein fluorescence intensity decreased compared with the model group. The relative expression - P< Conclusion of N Cad protein in lung tissues of YCF group was lower than that of the tetrandrine group ( 0.05). YCF can - improve the lung function, alleviate collagen deposition in lung tissues, and inhibit the epithelial mesenchymal transition in silicosis model rats, and then attenuates the progression of silicotic fibrosis.

Yinchenzhufu decoction (YCZFD) is a classic formula for treating Yin Huang syndrome, which can improve liver injury caused by cholestasis. However, the mechanism of action of YCZFD still remains unclear. This article used network pharmacology, molecular docking, animal experiments, and molecular biology methods to explore the mechanism of YCZFD in treating liver injury caused by cholestasis. A mouse model of acute cholestasis induced by lithocholic acid was used to investigate the effects of YCZFD on liver injury. The experimental procedures described in this paper were reviewed and approved by the Ethical Committee at the Shanghai University of Traditional Chinese Medicine (approval NO. PZSHUTCM190823002). The results showed that YCZFD could reduce the levels of blood biochemical indicators and improve hepatocyte damage of cholestatic mice. Then, multiple databases were used to predict the corresponding targets of YCZFD active components on cholestatic liver injury. An intersection target protein-protein interaction (PPI) networks based on String database and Cytoscape software was used to demonstrate the possible core targets of YCZFD against cholestatic liver injury. The results indicated that core targets of YCZFD include tumor necrosis factor, interleukin-1β, non-receptor tyrosine kinase Src, interleukin-6, etc. GO (gene ontology) and KEGG (kyoto encyclopedia of genes and genomes) enrichment analysis indicated that YCZFD may regulate the tumor necrosis factor signaling pathway, nuclear factor-κB signaling pathway, bile secretion, and other related factors to ameliorate the cholestatic liver injury. AutoDockTools software was used to perform molecular docking verification on the core targets and components of YCZFD. To verify the results of network pharmacology, UPLC-MS/MS method was used to determine the effect of YCZFD on levels of bile acid profiles in mouse liver tissues. It was found that treatment with YCZFD significantly reduced the content of free bile acids, taurine bound bile acids, and total bile acids in the liver tissues of cholestatic mice. Then, results from real time PCR and Western blot also found that YCZFD can upregulate the expression of hepatic nuclear receptor farnesoid X receptor, metabolizing enzyme (UDP glucuronidase transferase 1a1), and efflux transporters (bile salt export pump, multidrug resistance-associated protein 2, multidrug resistance-associated protein 3, etc) in cholestasis mice, promote bile acid metabolism and excretion, and improve bile acid homeostasis. Moreover, YCZFD can also inhibit pyroptosis and inflammation by regulating NOD-like receptors 3 pathway, thereby inhibiting cholestatic liver injury.

The effects of dietary supplementation with Clostridium butyricum on growth performance and humoral immune response in Miichthys miiuy were evaluated. One hundred and fifty Miichthys miiuy weighing approximately 200-260 g were divided into five groups and reared in 15 tanks with closed circuiting culture system. The animals were fed 5 diets: basal diet only (control) or supplemented of the basal diet with C. butyricum at doses of 10(3) (CB1), 10(5) (CB2), 10(7) (CB3) or 10(9) (CB4) CFU/g. Compared with the control, the serum phenoloxidase activity was significantly increased by the supplementation (P<0.05), acid phosphatases activity was increased significantly (P<0.05) at the doses of 10(9) CFU/g. Serum lysozyme activity peaked at dose of 10(7) CFU/g and in the skin mucus at dose of 10(9) CFU/g. Immunoglobulin M level in the serum and skin mucus was increased except at dose of 10(3) CFU/g (P<0.05). The growth at the dose of 10(9) CFU/g was higher than that of the control (P<0.05). It is concluded that supplementation of C. butyricum can mediate the humoral immune responses and improve the growth performance in Miichthys miiuy.
