Objective To investigate the anticoagultive effectiveness and specialty of sodium citrate comparing with hep- arin in continuous venovenous hemodiafiltration (CVVHDF).Methods 50 multiple organ disorder patients undergoing CWHDF were randomly divided into two groups:group A(sodium citrate)27 cases,group B(heparin)23 cases,blood e- lectrolyte,acid-alkali degree,cruor index changes,the blood coagulation of tube path way and blood filter were recor- ded.As the same time,side effects were observed in theraphy.Results The patients of two groups were kept stable vital signs,serum electrolyte and blood gas markers during the therapeutic periods.Moreover,ideal serum creatinine and urea clearance rate and uhrafiltration rate were obtained in all patients.The coagulation and longevity of blood filter of Group A are better than Group B,Group A without sigaificantly prolonged cruor index inside body,the dosage of calcium gluco- nate in Group A are greater than Group B.Conclusion Out body anticongulation of sodium citrate is more effective and reliable than regular heparin anticoagulation.

Objective To investigate the changes of inflammatory factors in the blood serum and their relationship with the immune status of patients with active pulmonary tuberculosis(TB).Methods A total of 97 cases of pulmonary tuberculosis were included from Feb 2003 to Oct 2005,57 of active TB,40 in resting period.Another 41 healthy people were used as normal control.ELISA and APAAP method were used to detect the level of TNF-?, IL-1,IL-6 and the changes of CD_(4),CD_(8)and CD_(4)/CD_(8).Results The levels of IL-1,IL-6,TNF-? were(15.3?1.3),(80.5?7.3) and(77.2?9.8) ng/ml in the normal controls,(33.7?3.6),(293.6?30.5) and(190.7?25.2) in the patients of active TB,and(18.2?2.1),(130.7?14.5),(87.5?10.2) ng/ml in the patients at resting period,which were highest in the patients of active TB.The ratio of CD_(4)and CD_(4)/CD_(8) was(32.3?2.9)% and(0.83?0.17) in the patients of active TB,lower than(48.2?4.4)% and(0.83?0.17) of normal controls.Conclusion The increase of inflammatory factors and decrease of immune activity were the clinical characteristic of patients with active pulmonary tuberculosis,which are of inverse relationship.

Objective To explore the clinical features of systemic onset of juvenile idiopathic arthritis (SoJIA) with atlantoaxial subluxation as the initial manifestation. Methods The clinical data from one SoJIA patient with atlantoaxial subluxation as the initial manifestation were retrospectively analyzed. Results A 9-year-old boy presented the head and neck movement disorder as the ifrst symptom, developed fever on the third day, then rapidly progressed on 23rd day, with a sharp decline in red blood cell, platelet, and hemoglobin, blood coagulation dysfunction, and a large number of bilateral pulmonary exudation. Ultrasonography showed excess lfuid in abdomen, chest, and pericardium. According to the 2001 version of the revised International College of Rheumatology standard, the diagnosis of SoJIA combined macrophage activation syndrome was conifrmed. Then treated with hemoperfusion, ifltration, and methylprednisolone combined with cyclosporine A, the disease was in remission. Conclusion For children with spontaneous atlantoaxial subluxation accompanied by the systemic symptoms, with no obvious skeletal deformity or acute inlfammation etc., should be alerted to the consideration of systemic juvenile idiopathic arthritis.

Objective To explore the effects of extract of Gingko biloba leaves (EGb) on learning, memory and hippoeampal heine oxygenase-1 (HO-1) expression in diabetic rats.Methods The behaviors of streptozotoein-induced diabetic rats were observed by Morris water maze for learning and memory after 6 months of diabetes.The HO-1 mRNA expression and protein expression in hippocampus of diabetic rats were detected by RT- PCR and immunohistochemistry respectively.Results The escape latency time in Morris water maze of diabetic rats was prolonged markedly.HO-1 mRNA and HO-1 protein expressions in hippocampus of diabetic rats were increased (1.635?0.326 vs 0.978?0.214,7.2?1.7 vs 1.9?0.5,respectively,both P＜0.01).The escape latency times in EGb (100,50 mg/kg) treated groups were shortened.HO-1 mRNA and HO-1 protein expressions in hippocampus were decreased at the same time as compared with diabetic group (100 mg/kg:0.954?0.144,2.0?0.8;50 mg/kg:0.988?0.154,2.5?0.6,all P＜0.01).Conclusion EGb can significantly inhibit HO-1 expression in hippocampus and improve learning and memory dysfunction in diabetic rats.

Objective To study the effects of vitamin B_6(VitB_6) injection on small intestinal peristalsis in mice and its mechanisms.Methods The mice were divided into 12 groups:calcium chloride injection group(1 mg/10 g),neostigmine methylsulfate injection group(0.001 5 mg/10 g),atropine sulfate injection group(0.005 mg/10 g),their combination with VitB_6 injection and high/low dose treated groups,high dose VitB_6 injection group(5 mg/10 g),low dose VitB_6 injection group(0.5 mg/10 g) and physiologic saline group(0.1 mL/ 10 g ).After administration 30 minutes,mice were intragastric administration Indian ink(0.1 mL/g),and they were luxated and put to death 20 minutes later.The mice belly were cut open,the length of intestine and distance of Indian ink that had moved were measured,and then the ink progradation rate were calculated.Results Compared with control group,the high dose VitB_6 injection could inhibit normal intestinal peristalsis of mice markedly(P0.05).Conclusions VitB_6 injection can inhibit hyperanakinesia of small intestine in mice,especially high dose.And this will be provided as theory foundation on enterospasm treatment.

OBJECTIVETo investigate the influence of total flavonoids of Elsholtzia splendens (TFES) on isolated ischemia/reperfusion rat hearts and its underlying mechanisms.

METHODSHearts isolated from male SD rats were perfused on the Langendorff apparatus and subjected to global ischemia for 30 min followed by 120 min of reperfusion. The cardiac infarct size was measured by TTC staining. Hemodynamic parameters and the level of lactate dehydrogenase (LDH) in the coronary effluent were measured. Absorbance at 520 nm was determined in isolated cardiac mitochondria exposed to 200 micromol/L CaCl2 to detect the opening of the mitochondrial permeability transition pore.

RESULTSPretreatment with TFES (1, 10, 100 microg/ml) for 5 min decreased infarct size and LDH release and improved the recovery of the left ventricular developed pressure. In mitochondria, the decrease of absorbance at 520 nm evoked by CaCl2 was greatly inhibited by TFES.

CONCLUSIONTFES prevents myocardial ischemia/reperfusion injury, and this cardioprotective effect is probably via inhibiting mitochondrial permeability transition pore opening.
