The microcirculatory perfusion of liver, spleen, kidney, small intestine andtail were measured by a laser doppler flowmeter after intravenous injection of agkistro-don antithrombotic anzyme (0. 05 U, 0. 025 U/100 g B. W.) in 40 hemorrhagic shockrats and 15 hemorrhagic rabbits. The results showed that 5～20 min after injection therenal perfusion increased significantly, but there was no marked increase of renal arteryblood flow when it was simultanously detected with a electromagnetic flowmeter, thoughthe urine was increased. Authors suggested that Svate may have decreased the resistenceof renal microcirculation and accelerate the veosity of renal microcirculation, thus theyincreased the microcirculatory perfusion in renal cortex.

Garcinia plants are one of the rich sources of natural xanthones and benzophenones which have attracted a great deal of attention from the scientists in the fields of chemistry and pharmacology. Recently, many structurally unique constituents with various bioactivities, especially anti-tumor activity, have been isolated from Garcinia plants. This concise review focused on the anti-cancer activity natural products isolated from Chinese Garcinia plants, and the research finding by authors and collaborators over the past several years were cited.

Objective: To investigate the effects of simulated altitude acute hypoxia on appetite and orexin mRNA expression in rats. Methods: Rats were exposed to hypobaric chambersimulating different high altitude (3000m,4000m,5000m,6000m) for different times (8h/d;1d,3d and 7d respectively), and the changes of appetite, weight gain, and the orexin mRNA expression in hypothalamus of rats were examined. Results: With the increasement of hypoxia time and simulated altitude, the total food intake of rats and the orexin A and B mRNA expression in hypothalamus decreased gradually as compared with control. After 7 days of hypoxia, the weight gain of rats was significantly different(P

This study aimed at exploring the effects of Griffipavixanthone,a natural small molecule extracted from Garcinia esculenta,on the autophagy and the mechanism behind it.Cervical cancer HeLa cells were selected as the model in vitro.Confocal microscopy,flow cytometry and immunoblotting were performed to know the impacts of Griffipavixanthone on signaling pathway over autophagy flux and calcium level;while nude mouse model was established to explore its anti-cancer action in vivo.It was found that Griffipavixanthone significantly induced GFP-LC3 puncta formation and the accumulation of LC3-Ⅱ/LC3-Ⅰ,and increased the protein expression of SQSTM1 in HeLa cells in a time and concentration dependent manner.MTT assay results showed that Griffipavixanthone inhibited the growth of HeLa cells in a dosage dependent manner,and eliminated the tolerance of tumor cells to nutrient starvation,which fastened the death of cells.Griffipavixanthone also down-regulated the concentration of calcium in the cytoplasm.Furthermore,the in vivo study indicated that intratumoral injection of Griffipavixanthone presented the anti-cancer effect to a certain extent.In conclusion,it was suggested that Griffipavixanthone inhibit autophagy with the potential to be developed into a clinical anti-cancer agent.Griffipavixanthone sensitized HeLa cells to nutrient stress-induced cell death through inhibiting the autophagy flux and the level of calcium in the cytoplasm.

Objective To evaluate the diagnosis and treatment of pseudoaneurysm .Methods The clinical data of 17 cases of pseudoaneurysm from Jan .2007 to Dec .2011 were reviewed retrospectively ,10 cases were caused by iatrogenic ,6 cases were drug caused by injection of poison ,and 1 case was was caused by trauma .2 cases of brachial artery pseudoaneurysm ,and 15 cases of arte-ria femoralis pseudoaneurysm .1 case was treated by simple compressive therapy ,the other 16 underwent surgical treatment and the pseudoaneurysm was removed ,in which 3 cases were treated by artery patch repair ,7 were treated by bypass with prosthetic grafts , 2 were treated by bypass with saphenous vein ,4 were treated by bypass with superficial femoral vein branch .Results There was no death except 1 case died because her family gave up ,All patients with signs and symptoms were significantly alleviated ,and there was no severe ischemia limb leading to amputation in postoperative follow-up .Conclusion The revascularization of the artery in pseudoaneurysm patients can make a significant improvement in the long-term quality of life .

0.05).Genotype B with YMDD mutations in 10 samples were found,including 2 YIDD(M+I) mutations and 8 YVDD(M+V) mutations.Genotype C with YMDD mutations in 68 samples were found,including 44 mutations I(M+I) and 24 mutations V(M+V).There was significant difference in YMDD mutation types between genotypes B and C(?2=5.5,P

Objective To evaluate a new gene therapy for the treatment of experimental occlusive arterial disease Methods Magnetic nanospheres were produced, VEGF gene was cloned for subsequent construction of eukaryotic expression plasmid The magnetic gelatin microspheres used in targeted gene therapy were prepared by emulsion crosslinking method The microspheres were injected intrafemorally in rabbits through contralateral femoral artery, and the ischemic limb was placed in a magnetic field Angiography was performed on day 10 and day 30 respectively The capillary density and the capillary to muscle fiber ratio were determined histochemically Results Compared to the controls there was significant collateral artery development in VEGF transfected group The capillary density and the capillary to muscle fiber ratio were significantly higher for the VEGF transfected group than for the control group. The capillary density of control was (125?23)/mm 2, and in VEGF group was (298?27)/mm 2, P

Objective To explore and analyze the application effect of hospital quality monitoring system in medical quality management.Methods 800 patients from March 2021 to March 2022 were selected as the control group and routine medical quality management was adopted;and 800 patients from April 2022 to April 2023 were selected as the experimental group and the hospital quality monitoring system was adopted for medical quality management.Results The complication rate and re-admission rate after implementation were significantly lower than before implementation,with statistical significance(P＜0.05).The satisfaction of patients after implementation was significantly higher than before implementation,and the difference was statis-tically significant(P＜0.05).The score of medical service quality after implementation was significantly higher than before im-plementation,and the difference was statistically significant(P＜0.05).Conclusion The application effect of hospital quality monitoring system in medical quality management is remarkable,and it is worthy of promotion.

Objective To systematically evaluate the effect of red ginseng on improving metabolic syndrome,and to provide basis for clinical practice.Methods Retrieval from PubMed,Embase,The Cochrane Library,Web of Science,Clinical Trials Gov,WanFang Data and CNKI databases,articles of RCTs about red ginseng on improving metabolic syndrome were included.The searching range was from the establishment of the database to May 2022.The articles were screened according to inclusion and exclusion criteria,and then the inclusion study was analyzed through RevMan 5.4.1 software.Results Totally 17 randomized controlled trials involving 957 patients were included.Compared with the control group,red ginseng exhibited significant effect on fasting blood glucose,total cholesterol,low-density lipoprotein,systolic blood pressure and diastolic blood pressure(P<0.05),and its effect was related to the disease,age,duration of administration and dosage.Conclusion Red ginseng could significantly improve the symptoms of hyperglycemia,hyperlipidemia and hypertension in metabolic syndrome,which provides a theoretical basis for clinical use of red ginseng in treating metabolic syndrome.
