Chinese Medical Equipment Journal 1993;0(06):-
Objective To explore optimal proposal and theorical mechanism for treatment of chronic ulcerative colitis(UC) with the therapeutic instrument inducting combined energies into anus.Methods 76 patients with mid-range chronic UC were sampled and divided into two groups randomly.Patients in both groups were all withdrawn from drugs and treated with the therapeutic instrument inducting the combined energies into the anus by choosing different combined energies.There were 41cases in the treated group and they were treated with intracavity electrod synchronizing with electrotherapy,heat therapy,magnetic therapy and massor.35 cases in the control group were treated with intracavity electrod synchronizing with heat therapy and magnet therapy.The two groups were compared after twelve months.Results The general improvement rate and cure rate of the two groups showed great significant difference(P

Objective To discuss the expression and the related factors of E-selectin in insulin-resistant(IR)rat endothelium. Methods Wistar rats were randomly divided into 3 groups: high fat feed,high fructose feed and the control feed(HF group,HG group and NC group). IR rat model was established by high fat feeding or high fructose feeding for 4 weeks and was evaluated with euglycemic clamp technique. E-selectin protein expression was detected by Western-blot analysis. Results The expression of E-selectin protein in vessel endothelium was increased in HF group and HG group compared with that in NC group (P<0.01), and higher in HF group than in HG group (P<0.05). E-selectin protein expression was correlated significantly with TG, FFA, FIns and HOMA-IR in HF group and HG group (P<0.05). Conclusions IR may cause the increased expression of E-selectin in endothelium of rats fed with high fat or fructose.

Objective Aim to explore how severe chyle blood serum effects on the End-point method of colorimetry,velocity method,immunological transmission turbidimetry(TIA)three types of common biochemical tests and their different influ-ences.Methods Collected 20 normal appearance serums,divided each pooled serum into A,B,C,D,E,F and G 7 experimen-tal groups and one control group.Each group contented for 1ml serum.Added intralipid 10,20,40,80,160μl and 320μl to the experimental groups from A to G in turn to prepare into different concentrations of simulate chylous samples.Tested each group by the End-point method of colorimetry,velocity method and TIA which represented by Glucose (Glu),uric acid (UA),Total bilirubin (TBil),aspartate aminotransferase (AST),gamma-glutamyl transpeptidase (GGT),lactate dehydro-genase (LDH),hypersensitive C reactive protein (hs-CRP),Apolipoprotein A1 (apoA1 )andβ2-microglobulin (β2-MG). Used pair T test for both experimental group and their control group.Results In terms of TIA,there were statistical differ-ences between all the experimental groups and their control groups in the three projects (t=-2.842~29.465,P<0.05).In terms of the End-point method of colorimetry,there were statistical differences between all the experimental groups and their control groups (t=-34.942~13.884,P<0.05)except for A group in Glu experiment (t=1.875,P=0.068>0.05).In terms of velocity method,there were no statistical differences between all the experimental groups and their control groups (t=-1.532~1.619,P>0.05)except for the B and C groups in GGT experiment (t=2.234&5.006,P<0.05).Conclusion Severe chyle blood serum had significant influence on the End-point method of colorimetry and TIA,as well as less influ-ence on velocity method.

AIM:To develop a new method to determine cucurbitacin B in Pedicellus Melo by capillary zone(electrophoresis(CZE).) METHODS:All the samples were analysed on a fused silica capillary(75 cm?75 ?m I.D.) by using 50 mmol/L sodium borate solution(containing 5% acetonitrile) as the background electrolyte with the running voltage at 12.0 kV and detection wavelength of 265 nm.And clorprenaline hydrochloride was applied as the internal standard. RESULTS:The results showed a good linear correlation between relative peak area of cucurbitacin B(y) and its concentration(x) over the range of 0.15~1.2 mg/mL.Regression equation was y=(0.003 4x)+0.058,r=0.999 7,and the average recovery for baicalin was 100.2% with the RSD at(2.11%). CONCLUSION:The method is rapid,simple,reproducible and produces low pollution.It serves as a novel way to determine cucurbitacin B.

AIM:To study the effect of contact system in monocyte adhesion induced by urokinase-type plasminogen activator (U-PA). METHODS:U937 cells were labeled with [3H] thymidine in the culture medium, test reagents were added into the cell suspension in 24-well plates. The counts?min -1 were counted in a liquid scintillation counter. RESULTS:U-PA-induced monocyte adhesion was inhibited by high-molecular-weight kininogen and kallikrein, and promoted by factor Ⅻ and plasminogen. CONCLUSION:these contact system proteins may be important modulators of U-PA-induced monocyte adhesion, a process which is involved in many pathophysiological events.

Aim To assay the mutagenicity of Enphorbia lunulata(EL) decoction and to modify the Ames test for evaluation the mutagenicity of herbal medicine samples.Method The mutagenicity of EL decoction was assayed by standard Ames test; the teratogenicity was done by mammalian bone marrow chromosomal aberration test. In modified Ames test system,the influence of histidine EL decoction was excluded by additional negative control, in which the test media was supplied with histidine (histidine amount equaled to the histidine in different concentration of EL decoction).Result The mutagenicity of EL decoction was positive in the standard Ames test. The teratogenicity of EL decoction was negative in mammalian bone marrow chromosomal aberration test. By the modified Ames tests,the mutagenicity of EL decoction was negative.Conclusion The standard Ames test is not suitable for evaluating the mutagenicity of EL decoction, but the modified Ames test is. The mutagenicity in vitro and the teratogenicity in vivo of EL decoction are all negative.

Objective To observe the impact of IL-1β on the expression of lectin-like oxidized LDL receptor 1 (LOX-1) and ATP-binding cassette transporter A1 (ABCA1) in human mesangial cell line (HMCL), and its association with cholesterol homeostasis of HMCL. Methods Levels of LOX-1 and ABCA1 of HMCL induced by IL-1β were examined by using real-time PCR and Western blot. Results IL-1β up-regulated LOX-1 mRNA and protein expression. Treated with 5 μg/L IL-1β, the levels of LOX-1 mRNA and protein reached the peak after 6 h and 24 h of stimulation and were 6.87 folds and 1.88 folds of control rspectively. The expression of ABCA1 mRNA and protein of lipid-loaded HMCL was down-regulated by IL-1β Stimulated with 5 μg/L IL-1β the expression of ABCA1 mRNA and protein decreased to the lowest level, 19.0% and 50.62% of the baseline respectively. Conclusions The expression of LOX-1 can be up-regulated while the expression of ABCA1 can be decreased by the stimulation of IL-1β. IL-1β can enhance dyslipidemia and influence the balance of cholesterol homeostasis of HMCL.

Objective To explore the role of apparent diffusion coefficient (ADC) value of diffusion-weighted imaging (DWI) in the differentiation between benign and malignant bone tumors. Methods Echo planar imaging DWI was performed in 18 patients with benign tumor or tumorous lesion and 26 patients with malignant tumor of bone. Three b-values (0, 500 and 1000 s/mm2) were applied. The lowest, highest, and whole ADC values were measured for each lesion, respectively. Results The lowest ADC values of benign bone tumor[ mean( 1.28±0. 49) ×10-3mm2/s ] were significantly higher than that of malignant tumor [ mean ( 0. 92±0. 35 )×10-3mm2/s, t = 2. 839, P < 0. 01 ]. The whole ADC values of benign bone tumor [ mean (1.62±0. 51 ) ×10-3mm2/s] were significantly higher than that of malignant tumor [ mean ( 1.21±0. 36) ×10-3mm2/s, t = 3. 092, P < 0. 01 ]. However, there were much overlapping between benign and malignant bone tumor in the lowest and whole ADC values. There was no significant difference for the highest ADC values between benign [. Mean ( 2. 02±0. 55 )×10-3mm2/s] and malignant bone tumor[ mean( 1.71±0. 65 ) ×10-3mm2/s, t = 1. 669, P > 0. 05 ]. Excluding cases of bone cyst and aneurismal bone cyst, the lowest, highest, and whole ADC values of benign bone tumor was (1.11± 0. 31 )×10-3mm2/s, ( 1.88±0. 49)×10-3mm2/s, and( 1.45±0. 35 )×10-3mm2/s, respectively. There was no significant difference for the lowest, highest, or whole ADC values between benign and malignant bone tumor (t = 1. 728, 0. 964, and 2. 012, respectively, P > 0. 05). Conclusion ADC value is useless for the differentiation between benign and malignant bone tumors.
