Objective To study and evaluate the consistency and diagnostic value of electrogastrogram(EGG) and gastroscopy in children′s gastrosis diagnosis.Methods A total of 136 children were checked with gastroscopy and EGG during the same period,then compared the diagnostic accordance rate with 2 ways,and analyzed the characteristics of EGG.Results EGG showed certain characteristics in different gastrosis.Diagnosis of EGG in the group of functional illness was consistence with gastroscopy at 95.8%;others were less than 40%.Conclusion EGG can be used as a method of special value to diagnose children′s functional gastrosis and a screening means in general gastrosis.

The necessity to carry out student-oriented teaching of Medical information retrieval and use course in medical postgraduate was analyzed according to its theory followed by an elaboration on its module setting, course management methods, course examination forms and teachers.

AIM: To study the effect of breviscapine on the oxidative stress in the liver and kidney in diabetic rats. METHODS: Diabetes was induced by injection of streptozotocin (ST Z). Rats were randomly divided into three groups: control group, model group, mo del group treated with breviscapine. 8 weeks after STZ injection, liver lesion w as evaluated using HE, oil red O staining and kideny lesion using PAS staining. Malondiadehyde (MDA) levels and antioxidant activities in liver and kidney tissu e were determined by spectrophotometric method. RESULTS: Light microscopy in HE staining showed that liver fatty score was significantly lower in the breviscapine group compared with model ani mals (0.55?0.43 vs 1.54?0.65, P

Arsenic trioxide has been used to treat lymphoma experimentally since it was used to treat acute promyelocytic leukemia successfully. Massive works in this field have been done throughout the world. It was found that arsenic trioxide exerted an anti-lymphomatic effect via many pathways, and many substances could increase or reduce this effect. Arsenic trioxide can be used to treat relapsed and refractory lymphomas resistant to other chemotherapies with some therapeutic effects and limited side effects, which indicates that arsenic trioxide is a new potential drug for lymphoma. This article is an overview about these foundational and clinical studies.

OBJECTIVEThe clinical effect of the Shi's cervical reduction technique for cervical spondylosis and related disorders has confirmed, however, there were few studies on the body motion during manipulation in vivo study. This study is to summary the law of motion and the motion characteristics of the right operation shoulder, elbow, knee and ankle joints by data acquisition and analysis with the 3D motion capture system.

METHODSThe markers were pasted on the head, trunk, left and right acromion, elbow joint, wrist joint inner side and the outer side of the inner and the outer side and the lateral upper arm, forearm lateral, anterior superior iliac spine, posterior superior iliac spine, trochanter, femoral and tibial tubercle, inner and outer side of knee, ankle, fibular head, medial and lateral in first, 2,5 metatarsal head, heel and dual lateral thigh the calf, lateral tibia of one manipulation practioner, and the subject accepted a complete cycle of cervical "Jin Chu Cao and Gu Cuo Feng" manipulation which was repeated five times. The movement trajectory of the practioner's four markers of operation joints were captured, recorded, calculated and analyzed.

RESULTSThe movement trajectories of four joints were consistent, while the elbow joint had the biggest discrete degree. The 3D activities of the shoulder and elbow were more obvious than other two joints, but the degree of flexion and extension in the knee was significantly greater than the rotation and lateral bending.

CONCLUSIONThe flexibility of upper limb joint and stability of lower limb joint are the important guarantees for the Shi's cervical reduction technique, and the right knee facilitated the exerting force of upper limb by the flexion and extension activities. The 3D model built by the motion capture system would provide a new idea for manipulation teaching and further basic biomechanical research.

OBJECTIVETo observe the effect of salidroside on tic behavior and in vivo dopamine DA) and serotonin (5-HT) levels in Tourette syndrome (TS) model rats.

METHODSForty rats were randomly divided into the blank control group, the TS model group, the haloperidol-treated group (0.5 mg/kg x d(-1)), and the salidroside-treated group (50 mg/kg x d(-1)), 10 in each group. TS rat model was induced by imino-dipropio-nitrile (IDPN). Peritoneal injection of haloperidol and salidroside was started from the 4th day of modeling in the haloperidol-treated group and the salidroside-treated group respectively. Normal saline was peritoneally injected to rats in the blank control group and the TS model group respectively. Stereotyped behavior was scored, and changes of DA and 5-HT levels in blood and striatum were measured before modeling, after modeling, and after intervention.

RESULTSCompared with the blank control group, the score of the tic behavior was elevated (P < 0.01) , levels of DA and 5-HT in plasma and striatum were reduced in the model group (P < 0.01, P < 0.05). Compared with the same group after modeling, the tic behavior score decreased and plasma DA levels increased in the two treated groups after intervention (P < 0.01). 5-HT content increased in the salidroside-treated group (P < 0.01). Compared with the model group after intervention, the tic behavior score was significantly reduced (P < 0.01), and DA levels in plasma and striatum were elevated (P < 0.01, P < 0.05) in the salidroside-treated group and the haloperidol-treated group. Compared with the haloperidol-treated group, the tic behavior score increased (P < 0.01), DA levels in plasma and striatum were lowered (P < 0.01, P < 0.05), the 5-HT level increased in plasma and striatum (P < 0.01, P < 0.05) in the salidroside-treated group.

CONCLUSIONSIn the salidroside-treated group, the tic behavior was significantly reduced, and DA levels in plasma and striatum were elevated. Its mechanism might be related to regulating activities of dopamine neurons in striatum.

AIM: To investigate the effects and mechanism of enalapril on nephritis of diabetic mice. METHODS: Diabetes was induced by injection of streptozotocin after uninephrectomy. Rats were randomly divided into three groups: control, diabetes, diabetes treated with enalapril (10 mg?kg~-1 ?d~-1 by gavage). 8 weeks after STZ injection, urine albumin excretion rate (AER) were measured, and glomerular morphology were observed by light microscopy. The levels of malonyldialdehyde (MDA) in renal tissue and urine as well as activities of superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GSH-PX) in renal tissue were determined. Immunohistochemistry for ED-1 (macrophage marker), monocyte chemoattractant protein-1 (MCP-1) and intercellular adhesion molecule-1 (ICAM-1) were performed by streptavidin-biotin complex (SABC) technique. RESULTS: Increased kidney weight, ratio of kidney weight to body weight, AER and expansion of mesangial as well as tuft areas on histological examination of the kidney were significantly attenuated by the treatment of enalapril (P
