Objective To study the effect of ligustrazini (LGT) and propofol (PRO) on hepatocellular energy metabolism in the reperfusion injury after hepatic ischemia in rabbits and its mechanism. Methods The rabbits were randomly divided into four groups (n=10 in each), hepatic ischemia-reperfusion (HIR) group, HIR+LGT group (B), HIR+PRO group (C) and HIR+ LGT+PRO group (D). The contents of adenosine triphosphate (ATP), adenosine diphosphate (ADP), adenosine monophosphate (AMP), total adenylic acid number (TAN), energy charge (EC), malondialdehyde (MDA), superoxide dismutase (SOD) and nitric oxide products (NO2-/NO3-) in the liver tissue were measured at 45 minutes after reperfusion. Results The contents of ATP, NO and SOD activity of the liver tissue in B, C, D groups were higher than those in HIR group (P

AIM: To observe the effects of ketamine on preventing the increase of postoperative morphine requirement induced by fentanyl.METHODS: Sixty women undergoing total abdominal hysterectomy by spinal anaesthesia were assigned to 4 groups consisting of placebo(normal saline,C),fentanyl(3 bolus of 1 ?g/kg,at 15 min intervals,F),ketamine(infusion of 15 ?g?kg-1?min-1 ketamine from the skin incision until 20 min before the end of the surgery,K),ketamine and fentanyl(infusion of 15 ?g?kg-1?min-1 ketamine from the skin incision until 20 min before the end of the surgery plus 3 bolus of 1 ?g/kg fentanyl,at 15-min intervals,FK).The cumulative morphine consumption,pain score,and adverse effects(nausea, vomiting,hallucination,dizziness and itching) were recorded at 1,3,6,12,24,48 h postoperatively.RESULTS: There were no significant differences in age,weight,duration of surgery and the post-operative sensory block time.The cumulative morphine consumption in group F was significantly higher than those in group C at 3,6,12 h postoperatively(P

To study the function of lipoprotein lipase (LPL)with Asn291 Ser and Lys312insC compound mutation in LPL gene knockout heterozygous (LPL~(+/-)) mice. The results showed that triglycerides, free fatty acids, blood glucose and weight of LPL~(+/-) mice were higher than those of c57 mice(P<0. 05). The expressions of LPL Mrna and LPL protein of LPL~(+/-) group were lower than those of c57 group(P<0.05). The injection of Asn291Ser +Lys312insC protein caused little change of the lipid mass and LPL activity,but the injection of normal LPL protein induced obvious decrease of lipid mass and increase of the LPL activity.

Objective:To find the correlation of wrist bone mineral density ( BMD ) to wrist synovitis and erosion , by comparing wrist BMD and ultrasonography .Methods: A number of 80 female RA pa-tients were examined by BMD measurement of the femoral neck , spine and non-dominant wrist using du-al-energy X-ray absorptiometry ( DXA ) .Synovitis of the wrist was examined by ultrasonography .The wrist joint ( radiocarpal joint , dorsal midline , and carpoulnar joint ) was assessed in the same side of DXA, with transverse and longitudinal scans for USGS synovial hypertrophy and proliferation , tenosynovi-tis,tendinitis and bone erosion .Colour and power doppler ultrasonography ( PDUS) were used to sum the synovitis score .Results:We found:( 1 ) In the study , 80 female RA patients were enrolled , the mean age was 54.6 ±13.3 (27.0-80.0) years, the disease duration was 48 (12-116) months, and the body Mass Index was 23.0 ±4.0 (14.8-31.2) kg/m2 .The Wrist BMD ( g/cm2 ) in RA significantly reduced, compared with normal controls (0.297 ±0.121 vs.0.420 ±0.180,P<0.01).(2) The Wrist BMD (g/cm2) exceeded in early RA compared with the established RA (0.326 ±0.103 vs.0.285 ± 0 .132 ,P<0 .01 );the positive rate of severe osteoporosis in wrist was lower in early RA compared with the established RA(47.8%vs.64.9%, P<0.05); the positive rate of bone erosion in wrist by ultra-sound was lower in early RA compared with the established RA (39.1%vs.56.1%, P<0.01).(3) The wrist BMD ( g/cm2 ) in RA with high disease activity reduced compared with moderate and low disease activity (0.267 ±0.140 vs.0.280 ±0.126) and (0.267 ±0.140 vs.0.320 ±0.103) respec-tively , P<0 .05 ) .The percentages of positive ACPA in the high and moderate disease activity groups were significantly higher than those in the remission group (85% vs.81.8% and 92.6% vs.81.8%, respectively).DAS28ESR was correlated with wrist BMD (r=-0.288, P<0.01).(4) A significant positive correlation was found between wrist and spine /femur BMD ( r=0.634, P<0.01, r=0.795, P<0.01), and a negative correlation between wrist and disease duration and DAS 28ESR (r=-0.286, r=-0.301,P<0.01).There was a highly significant positive correlation between wrist BMD and femur BMD (r=0.95,P<0.05).(5) RA patients in wrist osteoporosis group had higher RF positive rate and ACPA rate than wrist osteopenia group (75.5%vs.55.6%,P<0.05,100% vs.83.3%, P<0.05). The patients of BMD osteoporosis group had higher DAS 28ESR compared with osteopenia group (5.3 ± 1.8 vs.3.7 ±1.5, P<0.01).The percentages of synovitis (61.5%vs.51.7%, P<0.05), tendeni-tis (14.3%vs.10.0%, P<0.05) and bone erosion (54.2%vs.46.2%, P<0.05) in wrist by ultra-sonography in osteoporosis group were higher than those of osteopenia group .(6) The wrist BMD in ne-gative bone erosion group by ultrasonography was lower than that in positive bone erosion group [ (0.333 ± 0.107) g/cm2 vs.(0.264 ±0.125) g/cm2, P<0.01], also the PDUS score was higher than positive bone erosion group (4.53 ±1.40 vs.2.55 ±2.66,P<0.01).Compared with negative bone erosion group, the patients in positive bone erosion group had longer disease duration (96.0 ±104.7) months vs.(66.2 ±78.0) months, P<0.05), higher percentage of RF (81.0% vs.53.8%,P<0.01), ACPA (92.7%vs.79.5%, P<0.05).and higher DAS28ESR (5.4 ±1.8 vs.4.2 ±2.0,P<0.05).

Malaria vaccines are being developed against different stages in the parasite's life cycle. Although not directly protective ,the sexual stage vaccines would induce antibodies that would prevent infection of mosquitoes when ingestedin a bloodmeal containing sexual stage parasites. pfs25 has been tested to be an important candidate antigen for malarial transmission blocking vaccine . In this report we analyzed the complete code of pfs25 gene of Plasmodium falciparum PFD-3/YN isolate. The result shows that the gene encoding pfs25 of PED-3/YN isolate has a mutant which generates a PstI endonuclease restriction site and shares 99.2％ nucleotide homology with that of NF4 isolate.

AIM: To observe the relationship between the reversal effect of 4 alkaloids of TCM on expression of P170 being obtained multi-drug resistance to mouse S180 tumor cell induced by chemotherapy protocol of PFC and the adjustment of the cell apoptosis.And to discuss the difference among alkaloids of TCM on reversion of being obtained multi-drug resistance in clinic.To improve the curative effect thereby. METHODS: By the methods of less dosage of Chemotherapy PFC,to set up the mouse models of multi-drug resistance of S180 tumor cell.At the same time to give the mouse matrine,terandrine,oxymatrine and berberine hydrooh loride for 2 weeks and then to observe the P170,TOPOⅡ,Fas and apoposis by flow cytometry. RESULTS: Matrine and terandrine could obviously reduce the expression of P170,the activation of TOPOⅡ induced by Chemotherapy and increase the ratio of the express of Fas and the apopsis of drug resistance to tumor cell.And berberine hydrochloride could obviously reduce the expression of TOPOⅡ. CONCLUSION: The adjustment to the apoposis of tumor cell by matrine and terandrine is related to the reversion of being obtained multi-drug resistance to tumor cell' expression,besides the different degree

Diabetic rat model was induced by high fat diet combined with streptozotocin (STZ). After the model was established, blood samples were taken from jugular veins to examine plasma adrenocorticotropic hormone (ACTH) and corticosterone, and hypothalamus and pituitary were removed for real-time PCR. There were no significant differences in basal plasma ACTH and corticosterone level among control, obese, and obese diabetic rats (P=0.07). The corticosterone rhythm in obese and obese diabetic rats was impaired. Hypothalamus glucocorticoid receptors (GR) mRNA expressions yielded similar results in the groups, but 11β-HSD1 mRNA expression in obese diabetic rats was up-regulated ( vs control rats, P<0.05 ). The expressions of GR and 11β-HSD1 in pituitary of obese diabetic and obese rats were significantly down-regulated (both P<0.05). In the obese diabetic rats, the impaired glucocorticoid negative feedback was partly due to down-regulation of 11 β-HSD1 and GR expressions in pituitary.
