OBJECTIVETo explore the effect of Tanshinone II A on severe acute pancreatitis (SAP) lung injury (ALI) rats and its possible mechanism.

METHODSSD rats were injected with sodium taurocholate to induce SAP group, and then intervened with sodium tanshinone II A sulfonate ( STS group). Simultaneously a sham-operation group (SO group) was set up. There were 24 rats in each group. The survival state and wet-to-dry weight ratio of lung tissues were observed. Activities of myeloperoxidase (MPO) in lung were determined by MPO reagent kit. Pathologic changes of lung tissues were determined by Hofbuaer method. Expression levels of three cytokines, TNF-alpha, IL-1beta, and intercellular cell adhesion molecule-1 (ICAM-1) were detected by ELISA.

RESULTSThe survival state of rats in the SAP group was deteriorated. The wet-to-dry weight ratio, MPO activities, pathologic changes in lung tissues, and expression levels of TNF-alpha, IL-1beta, and ICAM-1 increased significantly more in the SAP group than in the SO group (P < 0.05). Compared with those in the SAP group, the survival state of rats in the STS group was improved; the wet-to-dry weight ratio, MPO activities, pathologic changes in lung tissues, and expression levels of TNF-alpha, IL-1beta, and ICAM-1 obviously decreased in the STS group (P < 0.05).

CONCLUSIONTanshinone II A had remarkable effect on SPA LI rats, which might be associated with changing cytokines levels and attenuating infiltration of lung inflammatory cells.

Objective To investigate the prevalence of nodular gastritis,duodenal ulcer before and after eradicative treatment of helicobactor pylori(Hp) infection in children with gastroscopy.Methods This was a retrospective analysis of 1 275 children,age ranging 1 to 16 years old,collected from our hospital in recent 10 years,detecting rates of before eradicative treatment and after eradicative treatment were analyzed.Gastroscopes were analyzed with regard to a possible association with the infection.Results The detecting rate(11.89%) of duodenal ulcer after eradicative treatment was lower than that(17%) before eradicative treatment(P

0.05).There was significant difference of curative effect before and after treatment of children with RAP(?2=6.74,P

Objective To evaluate the efficacy and feasibility of the coil-and-glue method for the reduction of lung volume in rabbit emphysema model.Methods Sixteen rabbits of emphysema model were divided into the occlusion group(n=10),in which both anterior bronchi were occluded using the coil-and- glue method,and the control group(n=6).The maximal static pressure of airway(P_(max)),peak expiratory flow(PEF),end-expiratory volume(EEV)and pressure of oxygen(PO_2)were measured at ante- emphysema,post-emphysema,1 week and 4 week after occlusion respectively.The expectoration(or migration)of coil and collapse of lung were also investigated.Results P_(max)was(20.0?1.3)and(17.1? 1.4)cm H_2O(1 cm H_2O=0.098 kPa)in the occlusion group at ante-emphysema and post-emphysema respectively.P_(max)was(19.2?1.4)cm H_2O in the occlusion group in the 1 week after the occlusion,while (17.1?1.5)cm H_2O in the control group(F=6.68,P

Three compounds were isolated from solid culture of endophyte Myrothecium roridum IFB-E091 in Artemisia annua. Their structures were determined as (S)-(-)-N-[2-(3-hydroxy-2-oxo-2,3-dihydro-1H-indol-3-yl)-ethyl]-acetamide (1), N-(4-hydroxyphenethyl)acetamide (2) and asperfumoid (3), in which compound 1 was a new indole derivative. In cytotoxicity assay, the compound 1 had no obvious inhibition activity in human hepatoma cell line SMMC-7721 and human cervical carcinoma cell line HeLa.

The data mining technology was introduced, and the law and peculiarity of TCM syndrome and treatment were analyzed in this paper. Concurrently, the application of the data mining in TCM researches on rule of syndrome and treatment was roughly summarized and its advantages and existing problems were pointed out. In order to enhance the efficiency and the appliance value of the mining technology and to accelerate the development of TCM research, the method for integrating multi-algorithms to make the mining was proposed.

Objective To explore the relationship between the serum level of E-selectin and S128R polymorphisms in the exon 4 of E-selectin gene and acute myocardial infarction (AMI) in local Han peoples. Method The genotype of E-selectin were detected by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method in 168 patients with acute myocardial infarction and 200 healthy controls,and the serum level of E-selectin was measured by enzyme-linked immunosorbent assay (ELISA).Results There was significant difference in frequencies of allele and genotype in S128R polymorphism between acute myocardial infarction and control groups respectively,The relative risk suffered from acute myocardial infarction of SS genotype was 2.234 times of the SR genotype (OR=2.234,95% CI:1.112～4.437),The serum E-selectin level was significantly higher among carriers of SR genotype as compared with SS genotype (41.65?8.87)?g/L vs (34.23?6.72)?g/L,P
