OBJECTIVE: To investigate the clinical features of primary biliary cirrhosis (PBC) and its treatment by integrated traditional Chinese and western medicine. METHODS: 16 PBC patients were observed. Ursodeoxycholic acid (UDCA) was used in the dose of 13 to 15 mg.kg(-1).d(-1), with some traditional Chinese herb prescription. Results (1) The proportion of women to men was 15:1, the mean age was 52.5 years. AMA-M2 was positive in 14 subjects (87.5%). Biliary tract enzymes and ESR were elevated in all subjects. The ratio of hypercholesterolemia (CHOL) and abnormality in IgM was high (62.5%). Fatigue, pruritus, arthralgia, jaundice, splenomegaly were noted in more than half cases. Every patient had one to four complications. (2) ALP, GGT and Glb declined evidently after 3 months' treatment by western medicine associated with traditional Chinese medicine, and declined markedly after 12 months' treatment (P<0.05 respectively). TBIL and CHOL declined gradually during the treatment course. Symptoms and signs were lightened. CONCLUSION: PBC has complicated and especial clinical features. UDCA therapy is effective in PBC, while traditional Chinese medicine has extraordinary effect in treating the symptoms and signs.

Warfarin is widely used as one of the coumarins anticoagulation drugs in the clinical.Every physician has been disturbed by its narrow therapic index and bleeding complications.It is a difficult thing for the doctor to use it rationally.However,recently,with the rapid development of molecule biology,some research find that gene polymorphism of pharmacodynamics and pharmacokinetics cause the individual variability in drug response.In this review,we focus on the latest development in pharmacogenomics of warfarin at home and abroad in order to give some suggestions for the individual use of warfarin.

To study the inhibitory effects of laminarin (acidic polysaccharide) J201A on the proliferation of human lung fibroblasts (HLF) and its related mechanism of action. Methods: Effect of J201A on the proliferation of HLF was evaluated by MTT assay, and the effects on cell cycle and synthesis of proteins of HLF were assessed by flow cytometry. The existence of J201A receptors on HLF was confirmed by fluorescent staining assay. Results:J201 A inhibited the synthesis of proteins and the proliferation of HLF at G0/G1 stage of cell cycle and J201A receptors existed on HLF. Conclusion:J201A exerted its antifibrotic activity by inhibiting HLF at G0/G1 stage of cell cycle and the synthesis of proteins.

OBJECTIVE:To establish an HPLC method for determining nicardipine hydrochloride(NCD) microspheres in cerebrospinal fluid(CSF) of rabbits by HPLC.METHODS:NCD microspheres were injected into the cistern of rabbits.Cerebrospinal fluid was sampled at different time points and NCD was separated on Agilent-Zorbax column at a flow rate of 1.0 mL?min-1 with column temperature of 30 ℃.The mobile phase consisted of methanol-water(75 :25,pH=6.0) and detection wavelength was set at 236 nm.RESULTS:The linear range of NCD was 2～128 ng?mL-1(r=0.999 8) with recovery of 98.07%.The RSD of intra-day and inter-day were both below 1.47%.The LOD was about 0.5 ng?mL-1.On 3～11 day after medication,the concentration of NCD fluctuated within(14.15?0.37) ng?mL-1.CONCLUSION:The method is simple,rapid and accurate for determination of NCD in cerebrospinal fluid of rabbits.

In the researches of space flight,studies of the effects of microgravity on visual orientation were relatively few.This paper reviews recent progress on this topic.It surveys the spatial orientation problems encountered in spaceflight including 0-G inversion illusions,visual reorientation illusions,EVA height vertigo,and spatial memory problems described by astronauts.A vector model for sensory cue interaction was briefly described.

Objective To compare the influence of aging on apoptosis and the expression of apoptosis-related protein in adult and aged male Wistar rat hearts after acute coronary artery occlusion. Methods The acute myocardial infarction rat model was established by left anterior descending(LAD)occlusion.A total of 115 adult and aged rats,aged 6-24 months,were included in the study.The rats were divided into 4 groups:aged model group,aged control group,adult model group and adult control group.Animals were killed 1,3,5 hours,1 and 7 days after coronary occlusion.Hemodynamic parameters[heart rate(HR),left ventricular systolic pressure(LUSP),left ventricular end-diastolic pressure(LVEDP),±dp/dtmax)]were obtained from each group at every time points.The apoptosis and necrosis of myocardium were detected with TUNEL way and TTC stain.The expressions of Bcl-2 and Bax were analyzed with immumohistochemical stain. Results DNA fragmentation occured 1 hour after coronary occlusion and apparently peaked earlier in the aged than in the adult rat hearts.At 3 hour,the apoptotic index of aged model group was obviousily higher than that in adult model group[(51.90±23.15)%us.(18.67±17.15)%,P<0.01].The basal levels of Bcl-2 and Bax were higher in the aged than in the adult rat hearts.The expression of Bcl-2 in aged model group and adult model group were 2.7±0.9 and 1.8±0.8,P<0.05.The expression of Bax in aged model group and adult model group were 6.2±2.9 and 4.2±1.5,P<0.05. Conclusions The ability of aged rats to resist ischemia is poor,aging may alter the expressions of Bcl-2 and/or Bax,increase cardiomyocyte apoptosis,thereby,enhance the myocardial dysfunction during acute myocardial infarction.

Hypoxia, one major characteristic of malignant solid tumors, not only changes the biological characteristics of tumor cells, but also is the main cause of the failure for conventional chemotherapy and radiotherapy. This paper summarizes the implications of tumor hypoxia and the corresponding techniques,then we present the change in tumor biological characteristics induced by hypoxia. Next we analyze the cause of tumor resistance to chemotherapy and radiotherapy. And finally,We discuss the three antitumor strategies targeting hypoxia, which opens a new path to conquer cancer.[

Objective To construct tissue engineered cartilage with bone marrow mesenchymal stem cells (MSCs) and allogeneic bone matrix gelatin (BMG). Methods Bone marrow was aspirated and MSCs were separated by consecutive 0.70(70%)(V/V) Percoll gradient centrifugation and fibronectin adhesion. In experimental group, rhTGF-?1 and rhIGF-Ⅰ were applied into DMEM to induce proliferation and chondrogenic transformation, while in control group only DMEM was used. Colony forming efficiency (CFE) of MSCs was calculated, procollagen ?1(Ⅱ)mRNA expression in cells was detected by RT-PCR, hexuronic acid in culture medium was measured by carbazole-sulfuric acid method. Allogeneic bone matrix gelatin (BMG) was prepared by successive defatting and decalcification, observed by scanning electronic microscope. Chondrocyte progenitor cells induced from MSCs were seeded into BMG to construct tissue engineered cartilage. Culture masses were sectioned and stained by Masson's trichrome. Results CFE was 21/106 in experimental group, significantly higher than that of control group, which was 3/106 (u=3.878, P
