ObjectiveTo explore the effects of Yiqi Yangyin Huoxue principle on the expression of neurotrophin-3 of the frontal lobe cortex neurons in diabetic rat brain. Methods The diabetic rat model was produced by intraperitoneal injection of streptozotocin(STZ).The Yiqi Yangyin Huoxue drugs was poured into the stomach of the treated group. The brains were taken and the expression of neurotrophin-3 was estimated with immunochemistry 8 weeks later. Results Immunochemistry showed that there were many positive cells in the frontal lobe cortex of the normal group and they were deeply dyed.Positive cells of the model group decreased and their color was shallow .The number and the color of positive cells in the treated group were close to that of the normal group. Conclusion The Yiqi Yangyin Huoxue principle can effectively improve the degenerating of the frontal lobe cortex neurons in diabetic rat brain.

Esophageal cancer is the leading cause of cancer-related deaths worldwide.A single intraoperative intervention is unlikely to benefit the outcome.A multimodal management plan that includes the use of TEA seems to demonstrate improved results in high-volume centers.Anesthetic management may contribute to the containment of pulmonary morbidity and anastomotic leakage by the use of TEA,protective ventilation strategies during OLV,prevention of tracheal aspiration,and judicious fluid management.

Objective:To compare the cardiovascular effects of sufentanyl and fentanyl as combined with propofol in anesthesia during laparoscopic cholecystectomy(LC).Methods:Patients undergoing LC were randomly divided into two groups: 60 patients in the Sufentanyl group(group S,0.3 ?g/kg) and 53 patients in the Fentanyl group(group F,3 ?g/kg).The mean arterial pressure(MAP),heart rate(HR),cardiac output(CO),and cardiac index(CI) were recorded before induction,before pneumoperitoneum,after pneumoperitoneum and at the end of operation.Results:There was no difference in MAP,HR,CO or CI between the two groups before induction.The values of HR and CO increased significantly in group F after preumoperitoneum comparing with the values before preumoperitoneum(P

Objective To investigate the effect of Buyanghuanwu decoction(BYHWD) on angiogenesis and Ang-1/Tie-2 expression after focal cerebral ischemia in mice. Methods Focal cerebral ischemia was induced by 30 min of middle cerebral artery occlusion followed by reperfusion. BYHWD (20 g/kg) was administered orally 24 h after ischemia and once a day. The neurological score and the corner test were used to evaluate sensorimotor function during 28 days after ischemia. The microvessels density and the expression of Ang-1/Tie-2 in the ischemic boundary zone were determined by immunohistochemistry on 28 days after ischemia. Results Compared with the model group, BYHWD significantly ameliorated neurological dysfunction and reduced the number of right turn during 3 to 28 days after ischemia(P＜0.05 ). In addition,the numbers of CD31 ,Ang-1 and Tie-2 immunopositive cells were (437 ±59) ,(389 ±61 ) and (251 ±42) at the boundary zone in model group 28 days after ischemia,respectively. However, BYHWD treatment significantly increased the numbers of CD31(609 ± 68 ), Ang-1 (551 ±66) and Tie-2 (342 ±46) immunopositive cells(P＜0. 01 ). Conclusion BYHWD promotes angiogenesis,which may contribute to recovery of neurological function after focal cerebral ischemia,and Ang-1/Tie-2 pathway appears to mediate BYHWD-induced angiogenesis.

Objective To look for and confirm the downstream regulated gene of microRNA (miRNA)-148a in pancreatic cancer cell line.Methods The target gene regulated by miRNA-148a was predicted through bio-informatics analysis.The plasmid containing desired gene and with luciferase 3'-untranslated region (3'-UTR) reporter was constructed.Pancreatic cancer cells BXPC-3 were transfected with analogs and inhibitors of miRNA-148a by liposomes.The activity of luciferase was measured to determine whether miRNA-148a directly connected with desired gene.The expression level of miRNA-148a was changed in BXPC-3 cells,and the changes of target gene v-verb-b2 erythroblastic leukemia viral oncogene homolog 3 (awian) (ErbB3) expression were detected by Western blot at protein level.The data were analyzed by one way ANOVA.Results There was a conservative binding site of ErbB3 with miRNA-148a detected by bio-informatics analysis,miRNA-148a directly combined with ErbB3 and the activity of luciferase decreased to (25.00+47.00) ％ of the negative control (F=4.66,P＜ 0.01).After miRNA-148a overexpression,the gray value of ErbB3 expression in BXPC-3 cells decreased to (26.16±4.69)％ of control group (F=6.563,P＜0.05).Conclusion miRNA-148a directly targeted and regulated the expression of ErbB3 in pancreatic cancer cell line BXPC-3.

Objective Clinical effects of dot from body skin irradiated xenogeneic skin improved composite graft.Methods Selected 80 patients with severe burn patients randomized after admission on the basis of conventional treatment,3-5 days line Crust treatment group transplanted autologous point-like skin irradiation pigskin coverage.Results Treatment of patients in group one week dressing see irradiated pigskin Tiefu full two weeks the pigskin was dry scab-like.Wound healing treatment group (29 ± 5) days (P ＜ 0.01) was significantly shorter than the control group(39 ±4) days.Wound healing rate of treatment is significantly higher than the control group (P ＜0.01).Wound infection rate reduced greatly reduce labor intensity and dressing,and reduce pain.1 year after scar formation in patients with good flexibility and functionality.Conclusions Punctate since improved composite body skin irradiated xenogeneic skin transplantation can improve skin graft survival rate,promote wound healing,treatment of a large area of the burn wound repair is feasible and effective.

Objective To investigate the relationship between the activity of Janus kinase/signal transducer and activator of transcription (JAK/STAT) signaling pathway in cerulein-induced pancreatic acinar cell line AR42J. Methods The in vivo model of AP was induced by cerulean treated pancreatic acinar cell line AR42J, then RPM and AG490 were given for intervention. Western blot was used to determine theexpressions of JAK1 and phosphorylation JAK1 ( P JAK1 ) , STAT1, PSTAT1 and TNFα, IL-1β, IL-6. The expressions of IL-6, IL-1 β, and TNFα mRNA were measured by RT-PCR. Survival rate of cells was evaluated by trypan blue stain. Results The relative expressions of JAK1, P JAK1, STAT1, P STAT1 and TNF-o, IL-1β, IL 6 without cerulean treatment were 0.09 ±0.04,0.14 ±0.08,0.21 ±0.09,0.12 ±0.12,0.10 ±0.02,0.08 ± 0.03,0.02 ± 0.02. After cerulean treatment, the expressions of abovementioned protein increased in a time-dependant manner, the expressions at 24h were 0.53 ± 0.09,0.53 ± 0.13,0.56 ± 0.09,0.55 ± 0.10,0.25 ± 0.04,0.25 ±0.09,0.27 ±0.07, which were significantly higher than those in the control group (P ＜0.05). 2 4 h after RPM and AG 4 9 0 inhibition, the expressions of TNF-α, IL-1 β, IL-6 proteins significantly decreased to 0.17 ± 0.03and 0.17 ± 0.01,0.15 ± 0.05 and 0.14 ± 0.07,0.19 ± 0.04 and 0.19 ± 0.05; their expressions of mRNA significantly decreased ( P ＜ 0.05 ). The cell survival rates in RPM and AG490 treatment group were (72.4 ± 11.2) %, (69.7 ± 9.8 ) %, and in cerulein-stimulated cells (42.2 ± 12.3 ) % ( P ＜ 0.05 ).Conclusions The JAK1/STAT1 signaling pathway was involved in pancreatic inflammatory response with cerulein stimulation. Early treatment with inhibitors to the JAK1/STAT1 signaling pathway might control the inflammatory response in acute pancreatitis.

Objective To investigate the relationship between acute biliary pancreatitis (ABP) and anomalous pancreaticobiliary duetal union (APBDU). Methods 131 patients with ABP were enrolled to test the serum total bilirubin (TB), alanine amintransferase (ALT), aspartate amintransferase (AST), alkaline phosphates (ALP), γ-glutamyl transferase (γ-GT). All the patients received medical treatment, and then these tests were performed again. Thereafter, all the patients underwent selective surgery and intra-operative cholangiography was performed to observe the pancreaticobiliary duetal union. Results 27 patients (20.6%) with APBDU were found in 131 patients. Among them, 8 cases (29.6%) was B-P subtype (TypeⅠ), 16 cases (59.3%) was P-B subtype (TypeⅡ) , and the remaining 3 cases was mixed subtype (TypeⅢ). A significant decrease of ALT, AST, ALP, γ-GT after non-surgical treatment in both group of APBDU and NAPBDU was noted (P＜0.05). The serum levels of ALT, AST,γ-GT in APBDU patients were (71.81± 23.19) U/L, (47.85±27.87) U/L, (52.86±31.49) U/L, respectively; and in NAPBDU patients were (51.96±15.40) U/L, (40.77±16.58) U/L, (34.86±26.47) U/L. The difference was statistically significant (P＜0.05). Condusions APBDU is an important etiology of ABP.
