OBJECTIVE:To establish the quality standard of Danchong liniment.METHODS:Cortex Moutan,Radix Isatidis,Rhizoma Paridis,Fructus Crataegi and Fructus Mume in the formula were identified qualitatively by TLC.The content of Paeonol was determined by HPLC in which Hypersil C18 column(150 mm?4.6 mm,5 ?m)was used with mobile phase consisted of methanol-water(45∶55)at a flow rate of 1 mL?min-1.The detection wavelength was set at 274 nm and the column temperature was set at 30 ℃.RESULTS:Clear characteristic spots of Cortex Moutan,Radix Isatidis,Rhizoma Paridis,Fructus Crataegi and Fructus Mume were noted in TLC identification.The linearity of Paeonol was good in the range of 0.048 2～0.482 0 ?g(r=0.999 9)with an average recovery of 99.01%(RSD=1.60%,n=6).CONCLUSION:The established quality standard can be used for the quality control of Danchong liniment.

Objective To evaluate the association between serum 25-hydroxyvitamin D3 [25 (OH)D3] and arterial stiffness in patients with chronic kidney disease (CKD).Methods Three hundred patients with CKD were included,and were divided into two groups based on serum 25(OH)D3 levels:vitamin D deficient [25(OH)D3 ＜ 20 μg/L] and vitamin D non-deficient [25(OH)D3≥20 μg/L].Brachial ankle pulse wave velocity (baPWV),which reflected arterial stiffness,was calculated using the single-point method.Clinical data were collected in details.Correlation between serum 25(OH)D3 level and baPWV was assessed by the single factor correlation test and multiple linear regression analysis.Results The prevalence of vitamin D deficiency was 62.7％(188/300).The concentration of 25(OH)D3 was (17.62±8.54) μg/L in total patients,but was (12.38±4.55) μg/L and (26.44±6.05) μg/L in the subgroups of vitamin D deficient and non-deficient,respectively(P ＜ 0.01).There was a higher value of baPWV in the group of vitamin D deficient than that of vitamin D non-deficient (1 827.34±429.11 vs 1 555.31 ±353.14,P ＜ 0.01).Serum 25(OH)D3 level and baPWV was negatively correlated in total patients(r=-0.38,P ＜ 0.01) and each stage of CKD(stage 2-5)[r=-0.30,P ＜ 0.05; r=-0.26,P ＜ 0.05; r=-0.46,P ＜ 0.01; r=-0.57,P ＜ 0.01].Multiple linear regression analysis showed that vitamin D level was independently associated with baPWV(Model 1:β=-0.18,P ＜ 0.01; Model 2:β=-0.17,P=0.01).Both models accounted for 50％ (R2=0.50) of total variance of baPWV.Conclusions Vitamin D deficiency is common in CKD,and a low 25(OH)D3 level is significantly associated with increased arterial stiffness in these patients.Clinical intervention studies are needed to clarify whether treatment with vitamin D decreases the risk of cardiovascular disease in patients with CKD.

Objective To continually observe the monocyte chemoattraetant protein-1(MCP-1) expression in rats with anilateral ureteml obstruction, and to explore the relationship between MCP-1 and p38MAPK, and as well as the nuclear transcription faetor-кB (NF-кB). Method Thirty-six rots were randomly assigned to sham op-eration group (contorl group) and unilateral ureteral obstruction group (UUO group). Renal tissues were examined under light microscope 8 h,24 h and 72 h after operation, Immunhistochemistry was used to measure the expression of MCP-1 and NF-кB. RT-PCR and Western bot were employed to determine MCP-1 mRNA and p38MAPK pro-tein,respectively.Serum creatinine and ure nitrogen were examined with biochemistry methods. Results Com-pared with control group, the expression of MCP-1 mRNA in UUO group dramatically increased (control group:0.401±0.039;UUO group 8 h:0.894±0.137;24 h: 1.416±0.135;72 h: 1.894±0.14, P<0.05).The explosion of MCP-1 protein in renal interstitium of UUO group also markedly increased (control group: 50.08±3.210. UUO group 8 h:108.25±4.325;24 h: 179.34±3.237;72 h: 230.12±3.026, P<0.05),and the expressions of NF-кB and p38MAPK in UUO group were also stimulated (p38MAPK: control group: 110.65±9.734. UUO group 8 h:200.15±8.326; 24 h:272.74±7.244;72 h:549.11±9.544, P<0.05). There were positive correlations between MCP-1 and p38MAPK as well as NF-кB(r=0.74,r=0.81,P<0.01).Conclusions Tne increased expression of MCP-1 may participate in the injury mechanisms of renal tubulointesti-tinm in UUO rats. The increased expression of p38MAPK may induce NF-кB expression in the tubules, and then NF-кB promotes the expression of MCP-1.

To propose the hypothesis of the requirement for optimum ratio of various active cons tituents of Chinese materia medica with desired effects, which suggests that both single drug and compound drug prescriptions have their own target effects corresponding to their main indications and their active constituents must be in optimum ratio This hypothesis was initially tested in an ischemic animal model The neuroprotection of Yushen Oral Liquor (YSOL, an oral liquor made of Chinese materia medica) on neuronal injury in CA1 region of rat hippocampus following transient forebrain ischemia was used as an index to evaluate the drug's effect By combination of HPLC and pharmacological method, the relationship of HPLC and pharmacodynamical results of each sample made of YSOL was studied to observe the chromatogram peaks representing the drug's neuro protective effects There are three peaks named as R1, R2, and R3 for YSOL, which closely correlate to the drug's neuronal protective effects and the relative weight but not the absolute quantity of those peaks plays a critical role in producing neuronal protective effects of YSOL on ischemia induced neuronal damage The results provide experimental data supporting our proposed hypothesis

AIM: To determine tanshinone Ⅱ_A and salvianolic acid B by HPLC gradient elution. METHODS: HPLC was used with Hypersil-ODS C_(18) column(150 mm?4.6 mm,5 ?m).The mobile phase consisted of methanol-water 0~20 min(35-90:6510),20-25 min(90-95:10-5),25-30 min(95:5)gradient elution.The flow rate was 1.0 mL/min with column temperature at 30 ℃.The UV detection wavelength was at 286 nm in 0-20 min and 270 nm in 20-30 min,respectively. RESULTS: The linear range of tanshinone Ⅱ_A and salvianolic acid B were in the range of 0.014 448-0.096 32(r=0.999 97), and 0.198 6-3.972 ?g(r=0.999 94),respectively.The average recoveries were 99.62%(RSD=2.28%) and 100.58%(RSD=2.5%),respectively.(CONCLUSION:) The method is accurate、sensitive、reproducible,and suitable for the quality control of Chaidan Jieyu Granules.

Methods In addition to conventional rhytidectomy, the operation included transection of lower orbicularis palpebrorum ligament ,excision of the herniated orbital fat, suspension of lower obicularis palpebuorum muscle. Results The method has produced a satisfied result in 25 cases since 1999. Conclusion On the base of conventional rhytidectomy, we transect the lower orbicularis palpebrorum ligament to elevate and stabilize the orbicularis muscle to the periosteum above the level of lateral canthus, which improves nasopalpebromalar groove and obtains more youthful appearance of the mid face.
