Objective To establish the quality standard for Jianpi Fugan Pills. Methods Angelicae Sinenis Radix and Atractylodis Macrocephalae Rhizome in the formulation were qualitatively identified by TLC. The content of ferulic acid was analyzed by HPLC. TIANHE C18 column (250 mm×4.6 mm, 5 μm) was used with a mobile phase of acetonitrile-0.085% phosphorous acid (17∶83). The content was detected at wavelength of 323 nm. The flow rate was 1.0 mL/min, and temperature was 25 ℃.

Objective To introduce the role of pancreatic stellate cells in pancreatic fibrosis and the progress in treatment of pancreatic fibrosis. Methods Relevant literatures were collected and reviewed. Results Pancreatic stellate cells activation was closely related to pancreatic fibrosis. Inhibition of pancreatic stellate cells activation could provide a new approach in clinical treatment of chronic pancreatitis. Conclusion Pancreatic stellate cells are the key to pancreatic fibrosis,which are becoming the target for anti-fibrosis of the pancreas and treatment of chronic pancreatitis.

Objective To investigate the characteristics of memory impairment in patients with ischemic cerebrovascular diseases(ICVD)for further understanding in the cognitive impairment at early stage.Methods Forty-six ICVD patients aged 49 to 80 years old and forty-six matched volunteers,all from the same hospital during Sep 2005 to Feb 2006,were enrolled.Mini-mental state examination(MMSE),clinical memory scale(CMS),Fuld object-memory evaluation(FOM)and rapid verbal retrieve(RVR)were used to evaluate the cognitive and memory function.Results The ICVD patients had lower scores in every memory function than the controls(P

BACKGROUND:Cholesterol is closely linked to the occurrence and progression of atherosclerosis. Current approaches to study celular cholesterol dynamics have their own limitations.
OBJECTIVE: To measure the cholesterol efflux rate of RAW 264.7 mouse macrophages by BODIPY-Cholesterol labeling and to explore the effects of extracelular cholesterol and lipopolysaccharide on the cholesterol efflux rate.
METHODS:RAW 264.7 cels were cultured in vitro with DMEM containing 10% fetal bovine serum, and labeled with BODIPY-Cholesterol for 1, 2, 4, 8 hours. Then, the cels were rinsed with serum-free DMEM and inoculated for 6, 12, 24, 48, 96 hours to optimize the labeling time and incubation time. We measured and compared the cholesterol efflux rates after cultured cels were treated with cholesterol, lipopolysaccharide, human sera with high cholesterol or human sera with normal cholesterol.
RESULTS AND CONCLUSION: The best labeling time for BODIPY-Cholesterol was 2-8 hours. Cholesterol efflux rates were gradualy decreased after the cels that were labeled for 2 hours were incubated with increasing concentrations of cholesterol (0.1, 0.5, 2.5 mmol/L,P< 0.01). Treating cels with lipopolysaccharide also decreased the cholesterol efflux rate (P < 0.05). Furthermore, the cholesterol efflux rate was decreased after cels were treated with human sera with high cholesterol (P< 0.05). These findings indicate that BODIPY-Cholesterol can be used to measure celular cholesterol efflux rate and to study the effects of extracelular cholesterol and lipopolysaccharide on the cholesterol efflux rate.

The majority of patients with malignant tumors have hypercoagulable state,which easily leads to thrombosis,and is closely related with recurrence of tumor metastasis.The formation mechanism of hypercoagulable state is related to tumor,tumor treatment,complications etc.The main diagnostic indicators are the platelet,cruor and fibrinolysis,P-selectin and lysosomal protein,blood rheology.Tumor patients with the high risk of thrombus should use low molecular weight heparin.Thromboembolism should be prevented in bedridden patients with tumor and tumor associated operation.Tumor patients with venous thromboembolism should be given thrombolytic treatment.Tumor patients with hypercoagulable state should be treated by antico-agulant therapy combined with chemotherapy.

The successful cryopreservation of reproductive cells has important practical significance in many fields. In order to improve the recovery rate and viability of cryopreserved cells, it is necessary to study the permeability characteristics of cell membrane to both water and cryoprotectant. In this paper we review the studies on membrane permeability of animal reproductive cell for the recent years. We firstly list the typical permeability data of spermatozoa and oocyte membrane for water and cryoprotectant. We then analyze the effects of these characteristics on the design of cryopreservation protocol. We also introduce the latest experimental methods to measure the cell membrane permeability.

Objective To optimize combined CT pulmonary angiography (CTPA) and renal venography (rCTV) and to evaluate its value for the detection of venous thromboembolism in patients with nephrotic syndrome (NS).Methods Ninety NS patients suspected of venous thromboembolism because of abnormal D-dimer value were included in this prospective study.The first 45 patients were defined as group 1 (protocol 1).These patients underwent CTPA,then rCTV 25 s after CTPA,last inferior vena cava scanning after another 25 s.The following 45 patients as group 2 (protocol 2).These patients underwent CTPA and then inferior vena cava scanning 50 s after CTPA,3 patients in group 2 were excluded because of unavailable CTPA or rCTV.Vessel enhancement of CTPA and rCTV,and radiation doses for two protocols were compared with independent sample student t test.Incidence and distribution of pulmonary embolism and renal vein thrombosis were recorded and compared by using Chi-square test.Results Enhancement values of pulmonary trunk for groups 1 and 2 were (335.5 ± 111.3) and (335.0 ± 76.0) HU,right renal vein were (142.7 ±33.3) and (140.7 ±25.9) HU,left renal vein were (141.6 ±26.4) and (138.8 ±33.6) HU respectively,without any statistical difference (t values were 0.026,0.322 and 0.452,P ＞0.05).Radiation dose to the patients receiving protocol 2 were lower than that of patients receiving protocol 1 [volume CT index,(19.7 ± 4.3) vs (13.6 ± 3.0) mGy; dose length product,(1019.9 ± 878.5) vs (532.0 ± 132.9) mGy · cm; both P ＜0.01].Of 87 NS patients,44 venous thromboembolism events were detected,resulting in the incidence of 50.6％ (44/87),including pulmonary embolism in 19 patients,renal vein thrombosis and pulmonary embolism in 17,renal vein thrombosis in 7,and inferior vena cava in one patient.The detection rate were 48.9％ (22/45) and 52.4％ (22/42),there was no significant difference (x2 =0.106,P =0.745).Conclusion Combined CTPA and rCTV with protocol 2 (CTPA and inferior vena cava phase scanning 50 s after CTPA) is suitable to clinical application and pulmonary embolism is the most common thromboembolism complication in NS patients.

Objective To evaluate the diagnostic accuracy of digital subtraction bone removal CT angiography (DS-BR-CTA) and dual energy bone removal CTA (DE-CTA) compared with conventional and rotational DSA. Methods A total of 264 patients underwent 3D-DSA were enrolled, 190 of them underwent also DS-BR-CTA, while 74 underwent DE-CTA as well. Aneurysms detected with DS-BR-CTA and DE-CTA were analyzed compared with 3D-DSA on per-patient and per-aneurysm basis. The sensitivity, specificity, positive predictive value and negative predictive value of two methods for diagnosis of aneurysm were calculated. Results Taking DSA as the standard, the sensitivity and specificity of DS-BR-CTA to detect intracranial aneurysms was 96.90％ and 98.36％ on per-patient basis, while 97.37％ and 99.97％ on per-aneurysm basis, and the sensitivity and specificity for the detection of aneurysm ≤3 mm was 88.89% and 98.36%. The sensitivity and specificity of DS-BR-CTA to detect intracranial aneurysms was 98.25% and 100% on per-patient basis, 95.52% and 100% on per-aneurysm basis, and the sensitivity and specificity for the detection of aneurysm ≤3 mm was 90.91% and 100%. Conclusion DE-CTA has a comparable diagnostic accuracy with DS-BR-CTA to diagnose intracranial aneurysms, and can be used in the routine workflow for detection of intracranial aneurysms.
