ObjectiveTo investigate the inhibitory effect of peroxisome proliferator-activated receptor-?(PPAR?) agonist on mesangial cell(MC) proliferation and extracellular matrix expression induced by angiotensin Ⅱ(Ang Ⅱ).MethodsThe incorporation of 3H-thymidine(3H-TdR) and cell count were used as the measurement of MC proliferation.MC cell-cycle was analyzed by flow cytometry.Mouse primary MC was treated with various concentration of Ang Ⅱ(1,10,100 nmol/L) in the presence or Absence of N-acytosistin(NAC) or rosiglitazone.Transforming growth factor-?1(TGF-?1),plasminogen activator inhibitor-1(PAI-1),and fibronectin(FN) mRNA expression were determined by real time-PCR.Reactive oxygen species(ROS) production was measured by 2,7-dichlorofluorescein diacetate(DCFDA) fluorescence.Results1.One hundred nmol/L Ang Ⅱ increased 3H-TdR incorporation and cell number by 2.14 and 2.32 fold,respectively.Ang Ⅱ-induced MC proliferation was inhibited by PPAR? agonist rosiglitazone with dose-dependent manner in mouse MC.2.One hundred nmol/L Ang Ⅱ stimulation for 24 h induced 48% MC processed to S and G2/M phase.Rosiglitazone significantly blocked Ang Ⅱ increased cell number in S and G2/M phase.3.Rosiglitazone reduced Ang Ⅱ-induced TGF-?1,PAI-1,and FN mRNA expression with dose-dependent manner.4.One hundred nmol/L Ang Ⅱ stimulation for 60 min increased ROS production by 3.85 folds.Rosiglitazone significantly inhibited Ang Ⅱ-induced ROS production.Ten ?mol/L rosiglitazone almost completely blocked Ang Ⅱ-induced ROS production.ConclusionPPAR? agonist rosiglitazone could block Ang Ⅱ-induced MC proliferation and extracellular matrix expression via inhibition of ROS production.

OBJECTIVETo observe the difference in clinical efficacy on focal vitiligo treated with heat-sensitive moxibustion in comparison with medication, and discuss its effect mechanism.

METHODSSixty-eight cases were randomized into a moxibustion group (38 cases) and a medication group (30 cases). Additionally, 20 healthy persons were selected randomly as a normal group. In the moxibustion group, the heat-sensitive moxibustion was applied to Hegu(LI 4), Quchi(LI 11), Yanglingquan(GB 34), Zusanli(ST 36), Xuehai(SP 10) and the others, once a day. In the medication group, triamcinolone acetonide cream was used externally and locally, twice a day. In the two groups, the treatment of 15 days made one session. The efficacy was observed after continuous treatment for 3 sessions. The hemorheology test was done in all of the subjects. The radioimmunoassay was adopted to determine the levels of Interleukin 2 (IL-2), Interleukin 6 (IL-6), Interleukin 10 (IL-10) and tumor necrosis factor (TNF-alpha) before and after treatment.

RESULTSThe levels of IL-6, IL-10 and TNF-alpha in vitiligo patients were higher significantly than those in the normal group (P<0. 01, P<0. 05), the level of IL-2 was lower significantly than that in the normal group (P<0. 01) before treatment. After 3 sessions treatment, IL-2 level was increased significantly in the moxibustion group and the levels of IL-6, IL-10 and TNF-alpha were reduced, without significant differences as compared with the normal group (all P>0. 05). But the differences were significant as compared with those in the medication group (all P<0. 05). The curative and remarkably effective rate was 76. 3% (29/38) after treatment in the moxibustion group, which was higher significantly than 13. 3% (4/30, P<0. 05) in the medication group.

CONCLUSIONHeat-sensitive moxibustion achieves very good clinical efficacy on focal vitiligo, which is probably via promoting blood circulation and regulating the levels of IL-6, IL-10 and TNF-alpha.

Objective To investigate the value of serum?-human chorionic gonadotropin(?-HCG) and progesterone monitoring in medicinal conservative treatment for ectopic pregnancy. Methods Sixty patients with ectopic pregnancy treated with methotrexate were divideded into group A(n=39,?-HCG0.05).The time of serum progesterone level declining to normal level was significantly shorter than that of ?-HCG in both group A and group B(P

AIM:To observed the variation regularity of corneal endothelial cells in patients with different diabetes duration after phacoemulsification, and investigate the effects of diabetes and its disease duration on corneal endothelial cells.
METHODS: Ninety-seven ( 135 eyes ) cataract patients with diabetes were selected randomly and divided into GroupⅠ( which diabetes duration ≥10a) and GroupII(which diabetes duration <10a) according to their disease duration. Additionally 62 (89 eyes) age-related cataract patients were randomly selected as the control group. The corneal endothelial cell density ( CD ) , proportion of hexagonal cell and coefficient of variation ( CV ) in the three group patients were measured respectively before phacoemulsification and after surgery. And the measurement results were statistically analyzed.
RESULTS:The corneal endothelial CD and proportion of hexagonal cell in the three group were decreased after surgery compared with preoperative. But the CV of corneal endothelial cells was increased on the 1 st wk and in 1st mo after surgery compared with the preoperative. The difference was statistically significant (P<0. 05). The corneal endothelial CD and proportion of hexagonal cell in the two diabetic groups were lower than the control group after surgery. However, the CV of corneal endothelial cells was higher than the control group. The difference was statistically significant ( P < 0.05 ) . There was no significant difference in the corneal endothelial CD, proportion of hexagonal cell and CV between the two diabetic groups before phacoemulsification (P>0. 05). The proportion of hexagonal cell in Group Ⅰ was lower than which in GroupIIafter surgery. While the CV was higher than which in Group II. The difference was statistically significant (P<0. 05).
CONCLUSION: Phacoemulsification has some damage on the corneal endothelial. Since the impact of diabetes on the morphology and function of corneal endothelial cell was related to the diabetic duration. So phacoemulsification has more obvious damage on the corneal endothelial in diabetic patients. And the diabetic duration was longer, the damage on the corneal endothelial in phacoemulsification was more easily.

Objective To investigate the effect of astragaloside,one of the active components of astragalus membranaceus,on myocardial nerve growth factor(NGF)expression in murine myocarditis model with coxsackievirus B(CVB_3).Methods One hundred Balb/c mice were randomly divided into 6 groups.Group A [n=10,treated with carboxymethylcellulose(CMC) 0.1 mL,ig,for 1 week] were served as normal controls group and group B(n=10,treated with 9% astragaloside 0.1 mL,ig,for 1 week)as high-dose control.Eighty infected mice treated with CMC and 1%,3%,9% astragaloside 0.1 mL,ig,for 1 week (n=20 in each group)were served as group C(myocarditic control group),D(low-dose intervention group),E(middle-dose intervention group),F(high-dose intervention group),respectively.The mice were killed and their hearts were removed after 14 days.The expression levels of NGF mRNA and protein in the myocardium were examined by RT-PCR and immunohistochemistry,respectively.Results The mortality was significantly reduced in 9% astragaloside treated infected mice that was 10%(2/20)vs 45%(9/20)in group C(P
