AIM:To study whether or not Huangshao Yinxue Granula(HYG) has the therapeutic effect on experimental psoriasis. METHODS: The mice were treated with HYG 3.125,6.25,12.5,and 25 g/kg(i.g.) for 1 or 2 weeks.We studied the effects of HYG on mitosis in mice vagina epithelium,the formation of granular layer in scale epidermis of mice tails,the changes in CD3, CD4 and CD8 factors of the serum in psoriasis-like mice and guinea-pigs. RESULTS: HYG could inhibit the mitosis in mice vagina epithelium,promote the formation of granular layer in scale epidermis of mice tails.It could also diminish the value of serum CD4/CD8 of mice to regulate abnormal immune reaction.HYG had evident therapeutic effect on the ear skin damaged with 5% propanolol in psoriasis-like guinea-pigs. CONCLUSION: HYG has therapeutic effect on psoriasis-like animal models.

Objective To investigate the predictive value of the whole nodule size and solid component size of lung adenocarcinoma manifesting as subsolid nodule(SSN) in three different dimensions for pathologic grade.Methods We evaluated retrospectively preoperative chest HRCT data of 125 patients with 127 SSNs surgically resected and pathologically conformed lung adenocarcinomas.All specimens were divided into two groups: a total of 69 SSNs in group A, including 22 AIS and 47 MIA;a total of 58 SSNs in group B, only including IAC.Computer aided diagnosis software were used to measure the one dimension maximum diameter of solid component with lung window setting(1D-SCLW),two dimension maximum diameter of solid component with lung window setting(2D-SCLW),one dimension maximum diameter of solid component with mediastinal window setting(1D-SCMW),two dimension maximum diameter of solid component with mediastinal window setting(2D-SCMW),one dimension maximum diameter of whole nodule with lung window setting (1D-WNLW), two dimension maximum diameter of whole nodule with lung window setting (2D-WNLW), and volume of solid component with threshold of-300 HU (SCT) of all SSNs.Results 1D-SCLW, 2D-SCLW,1D-SCMW,2D-SCMW,1D-WNLW,2D-WNLW and SCT of the group B were significantly larger than those of the group A(P=0.000).ROC analyses indicated that the diagnostic efficiency of SCT for the pathologic grade was the highest among 7 CT features(AUC=0.887, sensitivity:81%,specificity:93%);The cut-off values of 1D-SCLW,2D-SCLW,1D-SCMW,2D-SCMW,1D-WNLW, 2D-WNLW and SCT were 17.50 mm,14.75 mm,9.50 mm,7.75 mm,0.50 mm,1.25 mm and 139.00 mm3.Multiple Logistic regression analysis revealed that SCT was the independent predictor of pathologic grade(OR=4.978,95%CI=1.430-17.331,P=0.012).SCT of 139.00 mm3 or greater was a significant indicator of IAC.Conclusion Among the whole nodule size and solid component size of SSN in three different dimensions on preoperative HRCT, SCT is found to be the independent predictor of pathologic grade, which may provide reference for surgery.

Objective To investigate the predictive value of whole nodule size and solid component size of pulmonary subsolid nodules (SSNs)with different window setting on preoperative HRCT for pathologic grade in lung adenocarcinoma.Methods We retrospectively evaluated preoperative chest HRCT and pathological data of 125 patients with 127 surgically resected lung adenocarcinoma manifesting as SSNs.All specimens were divided into two groups:a total of 69 SSNs in group A,including 22 adenocarcinomas in situ (AIS) and 47 minimally invasive adenocarcinoma (MIA);a total of 58 SSNs in group B,including invasive adenocarcinoma (IAC).Observer 1 used computer aided diagnosis software to measure the volume of whole nodule with lung window setting (WNLW),volume of solid component with lung window setting (SCLW),volume of solid component with mediastinal window setting (SCMW) and volume of solid component with threshold of-300 HU(SCT) of all SSNs.Observer 2 randomly selected 50 SSNs and repeated all the measurements.The interobserver agreement regarding quantitative measurements were evaluated by using intraclass correlation coefficient(ICC).The differences of all quantitative features between two groups were evaluated by Mann-Whitney U test.All the quantitative features were evaluated by using univariate logistic regression analysis,significant quantitative features identified by univariate logistic regression analysis were included in the multivariate logistic regression and independent predictors of pathological grade were obtained.Receiver operating characteristic analysis was conducted for the independent predictive factors that exhibited statistically significant differences in the multivariate logistic regression.Results The interobserver agreement regarding quantitative features were excellent (ICC＞ 0.75).The WNLW,SCLW,SCMW and SCT of group B were significantly larger than those of group A (P＜ 0.001).The univariate logistic regression analysis indicated that WNLW,SCLW,SCMW and SCT were significant (P＜0.001),the multivariate logistic regression analysis indicated that SCT was the independent predictive factor (OR=1.013,95％CI:1.006—1.020,P＜0.001).When SCT larger than 139.00 mm3,SSN was significantly associated with IACs (AUC=0.887,sensitivity=81％,specificity=93％).Conclusion SCT of SSNs on preoperative HRCT can be used to distinguish between AIS-MIA and IAC,which may provide information for choice of operation.

Objective To investigate the effect of calcium antagonist verapamil on the function of rat?- cells and tolbutamide (D860)-induced insulin release.Methods Insulin released from isolated islets were measured in control,verapamil,D860,and verapamil+D860 groups.Furthermore,intravenous glucose tolerance test (IVGTT) was conducted in acute experiments treated with verapamil and D860 respectively to assess?-cell function in rats with the same allocation as in vitro.Another IVGTT was performed in the end of 4 weeks' treatment.The insulin contents in pancreas were assayed and pancreas islets morphology were observed with immunohistochemistry.Results Verapamil could inhibit insulin release from isolated islets.Verapamil group was [(1.244?0.082)ng?ml~(-1)?islet~(-1)]and control group (2.623?0.226) ng?ml~(-1)?islet~(-1)(P0.05).Also,similar results were obtained in normal rats during acute experiments and verapamil reduce the hypoglycemic effect promoted by D860. However,above results were not observed in the end of 4 weeks experiments,and no difference for insulin content and morphological change in islets was found among four groups.Conclusion Treatment of verapamil chronically does not impair islet function and interfere with the hypoglycemic effect of D860 in rats .

OBJECTIVETo investigate the matrix metalloproteinase-9 (MMP-9) expression in vascular endothelial cells stimulated by the serum obtained from children with Kawasaki disease (KD) during the acute phase in the absence and presence of MMP-9 small interfering RNA (siRNA).

METHODSMMP-9 siRNA plasmids were constructed and transduced into vascular endothelial cells (ECV-304) by liposomal transfection. ECV-304 were cultured in 6 different conditional media: KD serum + siRNA negative control, normal serum, KD serum + MMP-9 siRNA1 (pSilencer3.1-MMP1), KD serum + MMP-9 siRNA2 (pSilencer3.1-MMP2), KD serum + gamma-globulin, and KD serum. RT-PCR and Western blot were used to detect MMP-9 expression at mRNA and protein levels in ECV-304.

RESULTSThe mRNA and protein expression of MMP-9 in ECV-304 cultured with 10% serum from KD patients (2.49 +/- 0.03, 1.20 +/- 0.04) and KD serum + siRNA negative control plasmid (2.45 +/- 0.03, 1.15 +/- 0.03) were significantly higher than those cultured with 10% serum from normal control children (1.21 +/- 0.03, 0.52 +/- 0.03, respectively; all P < 0.01) and the increased MMP-9 expression could be significantly inhibited by MMP-9 siRNA1, MMP-9 siRNA2 and gamma-globulin (100 mg/ml, all P < 0.01).

CONCLUSIONSThe increase of MMP-9 expression in vascular endothelial cells induced by the serum from KD patients might take part in the formation of coronary artery lesions. Two customized MMP-9 siRNA plasmids (pSilencer3.1-MMP1 and pSilencer3.1-MMP2) can significantly inhibit both MMP-9 mRNA and protein expression.

Objective To observe the possible association of serum adiponectin level with testosterone level in patients with isolated hypogonadotropic hypogonadism(IHH).Methods The diagnosis of IHH was made,based on clinical presentations,laboratory examinations of hormones and GnRH stimulation test.Serum adiponeetin and testosterone levels were measured in 23 IHH patients and 15 normal men.Results After matched for weight,blood pressure and waist-to-hip ratio,serum testosterone level in IHH group was significantly lower than that in control group [(0.23?0.18 vs 4.20?1.90)?g/L,P

Objective To analyze three different classification criteria, the clinical characteristics of antiphospholipid syndrome(APS)in a cohort of Chinese patients. Methods From January 1996 to October 2006, APS patients diagnosed with different classification criteria were retrospectively studied. Results There were totally 120 APS patients fulfilled at least one criterion, One hundred and one patients fulfilled the 1988 Asherson criteria, 96 patients fulfilled the 1999 Sapporo criteria, and 115 patients fulfilled the 2006 Sydney criteria. The ratio of male to female in a cohort of 115 definite APS patients was 1 to 10.5. The mean period of the disease until entry into the study was 82.6 months, the mean age at study entry was(41?12)years. Ninety patients had thrombosis episodes, among which the most common presenting manifestations were deep venous thrombosis, stroke and skin vasculitis. Forty-six of 92 married women in our cohort had fetal morbidity. Catas- trophic APS occurred in 7 patients. The presence of anticardiolipin antibodies(aCL)was detected in 86 pa- tients, anti-beta-2 glycoproteinⅠantibodies in 58 patients and lupus anticoagulant(LA)in 27 patients. Conclusion The most common presenting manifestations are deep venous thrombosis, stroke and cutaneous manifestations. The sensitivity of Sydney classification criteria is improved by adding anti-beta-2 glycopreteinⅠantibody as one of the laboratory criteria. However, primary APS patients who only presented with thrombo- cytupenia and positive laboratory tests could not satisfy this criterion. In addition, the significance of autoanti- bodies to some coagulant factors in APS needs further study.
