Adopting prospective, multi-center, random, single-blind and equal rank-control methods, 226 patients with rheumatoid arthritis (RA) were divided into two groups. The 114 patients of the test group were treated with oral sustained release tablets of Tripterygium Wilfordii (TW-SR), 2 tablets twice a day for 4 weeks, 112 patients of the control group received tablets of Tripterygium Wilfordii (TW) orally 2 tablets 3 times per day for 4 weeks. Testing results showed the total effective rates of the two groups were 92.11 % and 90.65 %, respectively (P>0.05). The adverse reaction rate of TW-SR was 20.18%, which was lower than that of TW group of 70.54% (P<0. 01). Results of pre-clinical pharmacologic experimental study demonstrated that TW-SR has obvious anti-inflammatory, analgesic and immunosuppressive actions the same as TW, while the toxicity of TW-SR was less than that of TW significantly. 相似文献

Objective: To investigate the effect of Tripterygium polyglycosid on establishing airway eosinophil infiltration and related airway hyperresponsiveness of asthmatic mice. Methods: A mature murine asthmatic model was made with ovabulmin sensitized and challenged C57BL/6 mice. Forty mice were divided into four groups with 10 mice in each group: mice sensitized and challenged with saline (WS group), mice sensitized and challenged with ovalbumin (WO group), mice sensitized and challenged with ovalbumin and treated with Tripterygium polyglycosid (TP group) and Dexamethasone (DXM group). The mice were intraperitoneally injected with 20 μg chicken ovabulmin emulsified in injected alum on days 0 and 14, then were challenged with an aerosol generated from 1% ovabulmin on days 24, 25 and 26. Tripterygium polyglycosid was injected intraperitoneally at 50 mg/kg on days 25, 26 and 27 after ovabulmin challenge. Dexamethasone was administrated to mice at 2 mg/kg on day 21, 23 before ovabulmin challenge. The airway hyperresponsiveness, mucus production, eosinophils in parabronchial area and bronchoalveolar lavage fluid and the level of interleukin-5, granulo-macrophage clone stimulating factor in bronchoalveolar lavage fluid were measured as indexes of inflammation. Results: Tripterygium polyglycosid treatment after ovabulmin challenge completely inhibited eosinophil in?ltration in bronchoalveolar lavage fluid [(0.63±0.34)×104 vs. (75.0±14.8)×104, P<0.05] and the peribrochial area (12.60±3.48 mm2 vs. 379.0±119.3 mm2, P<0.05),mucus overproduction in airway (2.8±1.7 vs. 7.1±5.6, P<0.05), and ncreased interleukin-5 levels in bronchoalveolar lavage fluid (28.8±2.8 pg/mL vs. 7.5±3.5 pg/mL, P<0.05). Meanwhile, Tripterygium polyglycosid treatment after ovabulmin challenge also partially inhibited airway hyperresponsiveness. The level of granulo-macrophage clone stimulating factor in bronchoalveolar lavage fluid didn''t change with drugs intervention. Conclusions: The administration of Tripterygium polyglycosid could inhibit the established airway inflammation and reduce the airway hyperresponsiveness of allergic asthmatic mice. It provides a possible alternative therapeutic for asthma. 相似文献

Summary Ultrafiltration as a means to control hematocrit and blood volume during cardiopulmonary bypass was evaluated in two groups
of 15 mongrel dogs. In both groups, the fluid input and urinary output were similar (P> 0.20). The amount of filtrate ranged from 950 to 2600 ml (mean 1740.0±426.5 ml), and resulted in an average intraoperative
fluid balance of +424.9±131.4 ml. In the control group the fluid balance was +2693.6±222.4 ml, more than in the Ultrafiltration
group (P< 0.00l). The mean hematocrit and hemoglobin before ultrafiltration amounted to 13.22% and 4.96g% respectively, whereas after
ultrafiltration the variables increased to 23.33g% and 8.28g% respectively (P< 0.00l). Our results suggest that ultrafiltration is a relatively simple, safe and effective method of hemoconcentration
during cardiopulmonary bypass. 相似文献

Summary To evaluate the changes of 3′, 5′-cyclic adenosine monophosphate (cAMP), thromboxane A2(TXA2) and prostacyclin (PGI2) in cerebrospinal fluid (CSF) in the asphyxiated newborn and explore their roles in hypoxic-ischamic brain damage (HIBD).
Thirty-six full term newborns were divided into 3 groups, including 12 with moderate-severe hypoxic-ischaemic encephalopathy
(HIE), 13 with mild HIE, 11 without HIE (control group). The levels of cAMP, TXB2 (TXA2 metabolite) and 6-keto-PGF1α (PGI2 metabolite) in CSF and plasma were measured 36–72 h after birth by RIA, and the concentrations were expressed as nM/L (cAMP),
ng/L(TXB2 and 6-keto-PGF1α). The infants were followed-up at 6 and 12 month of age and Mental Development Index (MDI) and Psychomotor Development Index
(PDI) were measured using Bayley Scales of Infant Development (BSID). The CSF cAMP level in moderate-severe HIE group was
8.60±2.40, significantly lower than that of the mild HIE group (14.83±2.84) and the control group (24.43±2.39) (for bothP<0.01). The levels of TXB2 and 6-keto-PGF1α in CFS in the moderate-severe HIE group (206.06±29.74, 168.47±23.02, respectively) were significantly higher than in the
mild HIE group (83.37±28.57, 131.42±16.57, respectively,P<0.01) and the control group (41.77±21.58, 86.23±13.05, respectively,P<0.01). The level changes of cAMP, TXB2 and 6-keto-PGF1α in plasma in all groups were similar to those in CSF, but no significant difference was found between mild HIE group and
the control group (P>0.05). The follow-up results showed that MDI and PDI of the moderate-severe HIE group were the lowest (84.79±13.34, 83.50±13.28,
respectively), followed by mild HIE group (102.19±7.02, 99.94±9.08, respectively), with the control group being the highest
(116.63±12.08, 116.69±10.87, respectively). Univariate analysis showed some significant difference (the moderate-severe HIE
group vs. the mild HIE group or the control group,P<0.01; the mild HIE group vs. the control groupP<0.05). The results suggested that the concentration of cAMP, TXA2 and T/K ratio in CSF after neonatal asphyxia might be sensitive markers in evaluating the severity of brain damage in early
stage and predicting the future outcome.

To investigate the role of platelet membrane glycoprotein (GP) Ib/Ⅸ/Ⅴ complex and its subunit GP Ibα in patients with hemorrhagic thrombopathy (HT), the expressions of GP Ib/Ⅸ/Ⅴ complex and GP Ibα,defined as mean fluorescence intensity (MFI), were assessed by flow cytometry. The maximum aggregation of platelet was determined by turbidity method. These indicators were compared among 68 HT patients with the presenting complaint of hemorrhage, 33 well-controlled HT patients and 32 normal healthy subjects. The results showed that the MFI of GP Ib/Ⅸ /Ⅴ complex and GP Ibα was markedly lower in HT patients with current hemorrhage than that in the healthy subjects, with difference being statistically significant (P〈0.05). There was no significant difference in the expressions of GP Ib/ Ⅸ/ Ⅴ complex and GP Ibα between well-controlled HT patients and normal healthy subjects (P〉0.05). It was concluded that the expression of GP Ib/Ⅸ /Ⅴ complex, the receptor of thrombin and von Willebrand factor, was down-regulated in HT patients with current hemorrhage, which might result in the dysfunction of platelet aggregation and recurrence of HT. 相似文献
