The w or king principle,software and hardware composition,and the functions of the automa tic CMM(Chinese Materia Medica)boiling machine are introduced in this paper.Diff erent from other congener products' temperature control principle,time-sharing power control is applied to this system.The boiling process is more fit for CMM pharmacology than other products.The efficiency of the boiling machine is almost the same as the traditional one.The interrupt service subprogram is used in t his system to perform dynamic LED display.In order to control the output power, the duty ratio of the square-ware is adjusted to control the bi-directional thyr istor's conducting and closing time.Thus,the use of PWM control can be avoided,w hich is a bit complex in designing the software and hardware.The design process of this system is clear and simple.

Objective:To investigate the influence of Xuefu Zhuyu Decoction ( XZD) contained Drug-Serum on the expression of TLR4/NF-κB signals and LOX-1, TNF-α, ICAM-1, VCAM-1 in HUVECs, and to study its possible anti-atherosclerotic mechanism.Methods:HUVECs was cultured in vitro and divided equally into the normal group ,the model group,the ATV group and the XZD group in random.HUVECs were stimulated with LPS for 2 h,then treated separately with the drug-serum and atorvastatin for 24 h,finally measured the expression of TLR 4, MyD88, TRAF-6, NF-κB, LOX-1, TNF-α, ICAM-1 and VCAM-1 mRNA with real-time PCR,the expression of TLR4,NF-κB,LOX-1,TNF-α,ICAM-1 and VCAM-1 protein were analyzed by Western blot method .Results:Protein and mRNA expressions of TLR4,MyD88,TRAF-6,NF-κB,LOX-1,TNF-α,ICAM-1 and VCAM-1 increased significantly after LPS stimulation(vs normal control group,P<0.01),Xuefu Zhuyu Decoction decreased the high expression of TLR 4,MyD88,TRAF-6, NF-κB,LOX-1,TNF-α,ICAM-1 and VCAM-1(vs model group,P<0.05 ).Conclusion:Xuefu Zhuyu Decoction can block the high ex-pression of TLR4 and its downstream signal transduction pathway and the high expression of LOX -1, TNF-α, ICAM-1 and VCAM-1.Maybe it′s the mechanism of Xuefu Zhuyu Decoction exert the function of anti-artherosclerosis.

OBJECTIVETo study the effect of Buyang Huanwu Decoction (BHD), Xuefu Zhuyu Decoction (XZD), and Sijunzi Decoction (SD) contained serums on expressions of Toll-like receptor 4 (TLR4)/nuclear factor (NF)-κB signals, lectin-like oxidized low-density lipoprotein receptor-1 (LOX-1), tumor necrosis factor-α (TNF-α), vascular cell adhesion molecule-1 (VCAM-1), intercellular adhesion molecule-1 (ICAM-1), and to explore possible anti-atherosclerotic mechanisms.

METHODSTwenty New Zealand rabbits were divided into 4 groups at random, i.e., the normal control group, the BHD group (6.7 g/kg), the XZD group (3.6 g/kg), and the SD group (1.6 g/kg), 5 in each group. All medication lasted for 7 successive days. Two h after the final medication, about 50 mL blood was withdrawn from rabbit heart for preparing serums. Human umbilical vein endothelial cell ECV304 were cultured in vitro for 18 h and randomly divided into the blank control group, the model group, the Western medicine (WM) control group, the BHD group, the XZD group, and the SD group at random. ECV304, except in the blank control group, were stimulated with lipopolysaccharide (LPS) for 2 h. Those in the WM control group and CM groups were treated respectively with corresponding CM contained serum for 24 h. Finally gene and protein expressions of TLR4, myeloid differentiation factor 88 (MyD88), tumor necrosis factor receptor-associated factor-6 (TRAF-6), NF-κB, LOX-1, TNF-α, ICAM-1, and VCAM-1 were detected by fluorescent quantitative PCR and Western blot.

RESULTSCompared with the blank control group, mRNA expressions of TLR4, MyD88, TRAF-6, NF-KB, LOX-1 , TNF-cx, ICAM-1, and VCAM-1 increased significantly; protein expressions of TLR4, NF-κB, LOX-1, TNF-α, ICAM-1, and VCAM-1 also increased significantly in the model group (P < 0.01). Compared with the model group, mRNA and protein expressions of each index could be significantly inhibited in the BHD group, the XZD group, and the WM control group (P < 0.05). Besides, mRNA and protein expressions of each index could be significantly elevated more in the BHD group and the XZD group than in the WM control group (P < 0.05). No statistical difference existed in each index between the SD group and the rest groups (P > 0.05).

CONCLUSIONSThe mechanism of BHD and XZD for fighting against atherosclerosis might be associated with inhibiting TLR4/NF-κB signal transduction pathway and expressions of its downstream inflammatory factors such as LOX-1, TNF-α, ICAM-1, and VCAM-1. But SD showed no associated effect on atherosclerosis.

OBJECTIVETo observe the effect of Pi transportation, dampness resolving and phlegm expelling herbs (PTDRPEH) on the obesity degree, fat hormones, and leptin resistance in diet-induced obesity (DIO) rats.

METHODSAmong the 120 Wister rats, 10 were recruited as the blank control group (fed with basal forage), and the remaining 110 were administered with high-fat high-nutrition forage for 17 weeks. According to weight, we obtained 40 DIO rats and 10 diet-induced obesity resistance (DIO-R) rats. DIO rats were further divided into four groups, i.e., the DIO model group (normal saline, at the daily dose of 2 mL), the sibutramine group (at the daily dose of 1.6 mg/kg), the dampness resolving and phlegm expelling group (DRPE, at the daily dose of 3.2 g/kg), and the Pi transportation group (PT, at the daily dose of 3.2 g/kg). All were given by gastrogavage. Normal saline (2 mL) was given by gastrogavage to rats in the blank control group and the DIO-R group. The basal forage was administered to rats in the blank control group, while high fat forage was continually given to rats in the remaining five groups. Their body weights and body lengths were measured after 16 weeks of gastrogavage. All intra-abdominal fat was taken out to measure the degree of obesity and fat contents. Insulin resistance index (IRI), blood glucose, triglycerides, cholesterol, leptin, neuropeptide Y (NPY), tumor necrosis factor alpha (TNF-alpha), and adiponectin were detected after blood withdrawing. Leptin, TNF-alpha, adiponectin, suppressors of cytokine signaling-3 (SOCS-3), and other relevant adipose hormones and inflammatory cytokines were examined in the fat homogenate.

RESULTSCompared with the blank control group, DIO model rats' body weight, body mass index (BMI), fat factor, IRI, serum leptin, TNF-alpha, and SOCS-3 significantly increased (P < 0.05, P < 0.01); serum NPY, serum leptin, and adiponectin decreased (P < 0.05). Leptin increased and NPY decreased in DIO-R model rats. Compared with the DIO group, DIO-R model rats' body weight, BMI, fat factor, IRI, serum NPY, TNF-alpha, and SOCS-3 all decreased (P < 0.05, P < 0.01); leptin and adiponectin in serum and the fat homogenate all increased (P < 0.05, P < 0.01). After intervention with Sibutramine, rats' body weight, BMI, fat factor, and TNF-alpha in the fat homogenate obviously decreased (P < 0.05, P < 0.01). Serum TNF-alpha decreased, leptin and adiponectin increased in rats of the DRPE group (P < 0.05, P < 0.01). BMI, fat factor, IRI, leptin, and SOCS-3 showed a decreasing tendency, but with no statistical difference (P > 0.05). The body weight, BMI, fat factor, IRI, TNF-alpha, and SOCS-3 all decreased in the PT group (P < 0.05, P < 0.01); leptin and adiponectin in the serum and the fat homogenate increased (P < 0.05, P < 0.01).

CONCLUSIONSSibutramine could reduce body weight and TNF-alpha in the adipose tissue. Herbs of PT could inhibit fat diet-induced obesity and insulin resistance (IR), with superior effect to herbs of DRPE. Its mechanism might be closely related to promoting leptin and adiponectin secreted by fat, reducing leptin resistance, and elevating serum levels of leptin and adiponectin.

BackgroundAllogenic immunological rejection is still the common cause of keratoplasty failure.Organ culture is a good choice for gradually attenuating corneal antigeniciy.However,the complicated regulatory mechanism of such allogenic rejection with organ culture gratts is unclear until now.ObjectiveTo investigate the changes of several Thl/Th2 cytokines and T lymphocyte subsets in the rat corneal allogenic transplantation rejection with organ culture grafts.MethodsThirty-six SPF Wistar rats served as donors,and 72 SPF SD rats served as recipients in this study.Seventy-two SD rats were divided into two groups randomly.Organ culture and fresh grafts from Wistar rats were performed on 36 recipients SD rats,respectively.Six normal SD rats were served as the normal control.After transplantation,graft survival time was observed ; Aqueous humor levels of IL-2,IFN-γ,IL-4 and TNF-α were measured by enzyme linked immunosorbent assay.Immunohistochemistry was performed to examine CD25 expressions in grafts.Levels of TNF-αmRNA,IFN-γmRNA,IL-4mRNA and CD25mRNA in grafts were detected by using reverse transcription polymerase chain reagction.The levels of CD28subsets in peripheralblood were determined by Flow Cytometry.The use of experimental animals followed the Statement of ARVO.Results The mean rat graft survival time was longer in the organ culture grafts group( 13.78 d) than that with fresh gratts( 10.56 d)(t=14.945,P =0.000 ).The aqueous humor levels of IL-2,IFN-γ,IL-4 and TNF-α were higher in two allograft groups at day 6,day 13 and day 24 after transplantation than that in the normal control,which peaked at day 13,and the fresh grafts group had the highest level( F=324.891,416.416,240.661,364.533,P=0.000).At day 13,CD25 was weakly expressed in frozen section of two operation groups.The expression of TNF-α and IFN-γmRNA in organ culture grafts group was markedly less than in fresh grafts group at day 13 after surgeries (t =2.464,P =0.039;t=5.438,P=0.001 ),whereas there was no significient difference in IL-4 and CD25 mRNA levels between them (t=-0.782,P =0.457,t =0.712,P =0.497).The percentages of CD28 of the fresh graft group increased significantly and more weakly expressed in organ culture grafts group (P =0.016 ). Conclusions Th1/Th2 cytokines and CD28 lymphocyte subsets may play important roles during corneal allograft rejection with organ culture grafts.
