The endophytic bacterum 01-144 was marked by using the method of antib iotic-resistance. Colonization of 01-144 in tomato root and stem was investig ate d. Result showed that 01-144 colonized in the root and stem and the colonizing a bility in the root was stronger than in the stem after dipping seed or watering root treatmeat, It was also found that this bacterium could more easly colonized in the low stem than in the upper stem. The population fluctuation of 01-144 ha d the same trend in both root and stem i.e.first increased then decreasing, an d the fluctuation in the root was more even than in the stem.

Objective To summarize the management of cardiopulmonary bypass(CPB) for infants below 10 kilograms with congenital heart diseases.Methods From Jan 2010 to Apr 2011,the clinical datas of 122 infants aged from 1.5 months to 2 years with body weight 3 to 10 kilograms,who underwent open heart surgery under mild or moderate hypothermia CPB were retrospectively analyzed.Results Among all the 122 infants,CPB time was 13 ~ 118 min [(62.69 ± 21.48) min],aortic cross-clamp time was 0 to 86 min [(35.47 ± 19.51) min].All patients were spontaneous resuscitation and successfully weared from the machine,no severe complications associated with CPB occurred,3 infants died (2.46%,3/122) after operation.Conclusion Using membrane oxygenator,circuit tubing and artery filter with less priming,and highflow perfusion during CPB,maintaining hemodynamics stable,holding reasonable hematocrit and colloid osmotic pressure,good myocardial protection and ultrafiltration are the significant elements of the management of CPB in infants with weight less than 10 kilograms.

Objective To investigate correlation factor of anastomotic leakage after anus-preserving operation for low rectal cancer. Methods Clinical data of 128 cases in recent 3 years of low rectal cancer after anus-preserving operation were retrospectively analyzed. Results The incidence rate of anastomotic leakage in the group were 10.9%(14/128). The patients of male,were age of ≥ 65 years old and <7cm of the anal margin from lower tumor,dukes the later stages,complicated by obstruction, diabetes, and hypoalbuminemia. The take place easily anastomotic leakages in the patients which were(all P < 0.05). Conclusion The rate of anastomotic leakage after anus-preserving operation for low rectal cancer is related to personal factors ,tumor factors and complicating diseases ,etc.

This paper analyzed current problems and challenges facing hospitals in alarm management both abroad and at home. Based on a survey conducted on alarm management in hospitals, plus an analysis on different kinds of data interfaces and data exchange protocols of the medical equipment used in ICUs, a solution of alarm management is put forwarded which is based on alarm information integration and processing. It aims at improving medical equipment alarm management and reducing relevant adverse events.

The contents of cAMP and (14C)-AA metabolites in rabbit platelets were measured with RIA and radioactive TLC, respectively. PGE, could cooperate with the effect of CI-930. on platelets to increase the cAMP contents. It had no influence on the effect of CI-930 on metabolites of (14C)-AA, at the same time. SQ-22536 100?mol?L-1 could not chang the effect of CI-930 on platelets, which increase cAMP contents and affect AA metabolism. The date suggest that there is not relation between the effect of CI-930 on AA metabolism and on the cAMP contents in platelets.

The effects of C1-930, a known selective phosphodiesterase 111 inhibitor, on vascular resistance and rat aortic strip contraction were studied CI-930 025mg/kg injected into the perfused artery, reduced vascular resistance markedly in femoral artery and internal carotid artery in anaesthetized rats. The action lasted for about 15-20 min. CI-930 in vitro inhibited norepinephrine (NE) and TXA2/PGH, mimetic U-46619 induced rat aortic strip contraction significantly with PD, values of 6.71 and 5.5 respectively. The inhibitory effects of CI-930 on NE and U-46619 induced contraction were more potent than that of KG induced contraction. CI-930 0.01 - 10?mol/L exhibited a potential inhibitory effects on intracellular Ca2+ dependent contraction of rat aortic strip induced by NE, but had no effect on extracellular Ca2+ dependent contraction. The results suggest that CI-930 can possess a potent intracellular Ca2+ dependent vasodilating effects in vitro and in vivo.

Localized scleroderma (LoS) is a chronic autoimmune skin disorder characterized by fibrosis and hardening of the skin and subcutaneous tissues, potentially affecting deeper tissues and other organs. Currently, China lacks evidence-based guidelines for the diagnosis and management of LoS, which poses a challenge to disease recognition and leads to significant variation in treatment strategies across medical centers. To address this problem, we plan to establish a nationwide, multidisciplinary expert team through the Chinese Society of Plastic Surgery to initiate the development of the
