The compounded prescription of Chinese crude drug is a key problem in the study of traditional Chinese medicine.A new research field that focuses on the group of effective fractions of Chinese crude drugs becomes more important as the result of combination of the theorem of traditional Chinese medicine and techniques of modern medicine.Up to date,the researches on this field are preliminary,remaining a lot of subjects to be explored.

AIM　To investigate the structural and functional remodeling of thoracic aortae in sinoaortic- denervated (SAD) rats. METHODS　SD rats underwent either SAD or sham-operation at the age of 10 weeks. Sixteen weeks after operation, the contraction and relaxation of the thoracic aortae were measured in isolated preparations; The morphological changes of arteries were examined by using histopathological method and computer image analysis. RESULTS　The NE-induced contraction was increased and Ach-induced relaxation of aortic rings was depressed in SAD rats; The structural remodeling of thoracic aortae was characterized by medial VSMC hypertrophy and matrix accumulations. CONCLUSION　Vascular functional and structural remodeling can be found in sinoaortic-denervated rats.

Objective To evaluate the value of volume rendering technique of MSCT in the diagnosis of pediatric pectus carinatum. Methods MSCT data of 36 children with pectus carinatum were collected.Volume rendering and multiplanar reformation recon-struction techniques were adopted at a postprocessing station.Results There were 35 cases of chondrogladiolar variant and 1 case of chondromanubrial variant,27 cases were symmetric and other 9 cases were asymmetric.VR technique clearly demonstrated the abnormal changes of sternum,costae and costal cartilages.Conclusion VR technique of MSCT can fully display the three-dimension morpho-logical changes of pediatric pectus carinatum,which can supply accurate information for minimally invasive treatment procedure.

Objective To study the impact of different low concentrations of cerium oxide for hepatocellular carcinoma cell prolifera-tion.Methods Three different types of hepatoma cells (Huh7, HepG2,7721) were cultured,and added different concentrations of cerium oxide (0.005,0.01,0.05,0.1,1 μg/mL),of which the cell proliferation was detected by CCK8.The apoptosis-related genes was detected by qRT-PCR technology.The cell cycle was analyzed by flow cytometry.And the effect of low concentration cerium oxide on hepatocellular carci-noma cells tumorigenicity was confirmed by the nude mice experiments.Results CCK8 experiment showed that low concentrations of cerium oxide could promote proliferation of hepatocellular carcinoma cell, especially in concentration of 0.01μg/mL.The qRT-PCR showed that low concentration of cerium oxide could inhibit the apoptosis of hepatocellular carcinoma cell.The flow cytometry analysis had not found any effect of cerium oxide on cell cycle.The tumorigenicity experiments confirmed that low concentrations of cerium oxide could enhance the tumorigenic ability of hepatocellular carcinoma cell.Conclusion Low concentration of cerium oxide can significantly improve the proliferation of liver cancer cells.

Objective: To measure IQ and MQ of patients with cerebral vascular diseases (CVD) involving different cerebral lobes and basal ganglia areas. To provide useful data for clinical assessment of brain functions with respect to degree and range of IQ and MQ impairments. Methods: 60 cases of localized CVD were confirmed by clinical diagnosis and CT scan. The patients were evaluated by the WAIS-RC and WMS-RC after convalescence. Results: There were reliable differences between patients and normal controls ( P

目的探讨对老年2型糖尿病患者行空气净化前后动脉血氧分压(PaO2)和二氧化碳分压(PaCO2)的变化。方法55例老年2型糖尿病患者分为观察组(29例)和对照组(26例)。观察组患者所处疗养室每日24h进行空气净化。分别于净化前、净化后第2、3、4周抽取动脉血检测PaO2 、PaCO2 、PH值和氧饱和度。 结果空气净化4周后,观察组PaO2、PaCO2 、氧饱和度有明显改善(P<0.01),PH值无显著性变化。结论空气净化能改善老年2型糖尿病患者的PaO2 、PaCO2。

OBJECTIVE: To analyze the features of orbital fracture and to discuss its forensic expertise points. METHODS: One hundred and thirty cases of simple orbital fracture from 2010 to 2012 collected from one public security bureau were retrospectively analyzed such as age, gender, tools, position and morphology of the fracture, periorbital and orbital compound injury and the follow-up results after 6 months. RESULTS: In the 130 cases, the wounded were mainly young men and hit by fist. The fracture of simple medial orbital wall accounted for up to 81.5% in all cases. In the periorbital and orbital compound injury, laceration and contusion of eyelid and ethmoidal cellules and maxillary sinus always occurred. After 6 months follow-up, there were 30 cases of comminuted fracture remained enophthalmos compared with the uninjured side. CONCLUSION It is inappropriate to judge the fracture of simple medial orbital wall as minor injury. We should judge the degree of simple orbital fracture after the injury is stable. Detailed ophthalmology inspection is necessary for forensic expertise of simple orbital fracture.

OBJECTIVETo explore the effect of Sedum sarmentosum Bunge Extract (SSBE) on severe acute pancreatitis (SAP) induced acute lung injury (ALI) model rats and their excessive inflammatory reactions.

METHODSForty-two healthy adult male Sprague-Dawley (SD) rats were randomly divided into 3 groups, the sham-operated control group (C), the SAP group (SAP), and the SSBE treated group (SSBE), 14 in each group. SAP induced ALl rat model was induced by retrograde injection of 5% sodium taurocholate (1 mL/kg) into the pancreatic duct. SSBE (100 m/kg) was administrated subcutaneously after the establishment of the SAP model. Equal dose of SSBE was injected again 12 h later. Equal volume of normal saline was administrated in the same way for rats in the C group and the SAP group. Rats were sacrificed after successful modeling and samples taken at 12 and 24 h. Pathological changes in the pancreas and the lung tissue were observed under light microscope. The ascites, serum amylase (AMS), wet/dry proportion (W/D) of the lung tissue, activities of myeloperoxidase (MPO), interleukin-1 (IL-1), IL-6, and tumor necrosis factor-alpha (TNF-alpha) were also measured.

RESULTSAscites and serum AMS activities significantly increased; MPO, IL-1, IL-6, TNF-alpha contents, and W/D ratio also significantly increased in the SAP group, when compared with the C group (P<0.05). Compared with the SAP group, those parameters were all attenuated in the SSBE group at 12 and 24 h (P<0.05, P<0.01). Pathological changes in the pancreas and the lung tissue were alleviated in the SSBE group under light microscope. The injury degree ranged between that of the C group and the SAP group.

CONCLUSIONSSBE could relieve the ALl in SAP model rats, which could be achieved through alleviating inflammation responses of SAP rats.
