Objective To investigate the relationship between Sjgren′s synd rome and associated other skin diseases. Methods Clinical features, laboratory a nd histopathological findings and causes were analyzed retrospectively in 13 cas es of Sjgren′s syndrome. Results Thirteen patients were studied, including 1 male and 12 female, the mean age of onset was 35.3 years old. All 13 cases prese nted features of xerostomia and xerophthalmia. The diagnosis was confirmed by po sitive Schirmer′s test, corneal fluorescein staining, and sialography. The asso ciated other dermatoses were verruca planae, pemphigus, lichen planus, vitiligo, herpes zoster, herpes simplex and systemic lupus erythematosus. All cases were treated with Chinese traditional and western medicines. Twelve cases improved ma rkedly, one eventually died of liver and renal failure and circulation failure. Conclusions The pathogenesis of Sjgren syndrome may be linked to autoimmunity, and immunological aberration has been implicated in most of associated skin dis eases. The intrinsic relationship between Sjgren syndrome and associated other dermatoses needs further investigation.

Objective To investigate the effect of curcumine on the expression of matrix metalloproteinase-9 (MMP-9) in human umbilical vein endothelial cell (HUVEC). Methods HUVEC were cultured and identified in vitro .After cultured with curcumine at different concentration for 24 hours, the expression of MMP-9 in HUVEC was detected by cytoimmunochemical staining method and ELISA . Results All concentrations of curcumine can restrain the expression of HUVEC after co- culturing with the cells for 24 hours. The inhibitory effect got stronger with the increase of the concentration of curcumine. Conclusion The curcumine can depress the expression of matrix metalloproteinase-9 in HUVEC obviously.

To assess the normal value of left ventricular twist (LVtw) and examine the changes with normal aging by 2-dimensional ultrasound speckle-tracking imaging (STI), 121 healthy volunteers were divided into three age groups: a youth group (19-45 y old), a middle-age group (46-64 y old) and an old-age group (> or = 65 y old). Basal and apical short-axis images of left ventricular were acquired to analyse LV rotation (LVrot) and LVrot velocity. LVtw and LVtw velocity was defined as apical LVrot and LVrot velocity relative to the base. Peak twist (Ptw), twist at aortic valve closure (AVCtw), twist at mitral valve opening (MVOtw), untwisting rate (UntwR), half time of untwisting (HTU), peak twist velocity (PTV), time to peak twist velocity (TPTV), peak untwisting velocity (PUV), time to peak untwisting velocity (TPUV) were separately measured. The results showed that the normal LV performs a wringing motion with a clockwise rotation at the base and a counterclock-wise rotation at the apex (as seen from the apex). The LVtw velocity showed a systolic counterclock-wise twist followed by a diastolic clockwise twist. Peak twist develops near the end of systole (96%+/-4.2% of systole). With aging, Ptw, AVCtw, MVOtw, HTU and PUV increased significantly (P<0.05) and UntwR decreased significantly (P<0.05). However, no significant differences in TPUV, PTV and TPTV were noted among the 3 groups (P>0.05). It is concluded that LV twist can be measured non-invasively by 2-dimensional ultrasound STI imaging. The age-related changes of LVtw should be fully taken into consideration in the assessment of LV function.

Objective To assess the influence of the risk factors of coronary heart disease(CHD) on the prognosis of pereutaneous coronary interventions (PCI). Methods The risk factors of CHD was retrospectively col-lected from 446 patients (mean age (SD) : 60.23(9.75) yrs,84.97% male )who were admitted to the First Affili-ated Hospital of Lanzhou University from January, 2007 to July, 2008. These patients were diagnosed as CHD and treated with PCI. Major adverse cardiac events (MACE) were followed up for 12 months after PCI,and its associatian with the risk factors of CHD was investigated. Results Among all the patients,2.24% (10/446) had family history of CHD, 20.63% (92/446) was complicated with diabetes, 52.26% (242/446) with hypertension, 42.15% (118/446) with dyslipidemia, 62.33% (278/446) of the patients was overweight, and 57.85% (258/446) was smoker. Within 12 months of follow-up, MACE incidence rate were 5.83%. Univariate analysis showed the propor-tions of female,family history of CHD, overweight, hypertension and smoker were significandy different between the patients with MACE and those without MACE (χ~2=4.133,6.848,3.997,3.939,4.120, respectively,P<0.05). Logistic regression analysis showed family history and overweight increased the risk of MACE (OR=7.383 and 10. 504,respectively,95% CI=1.639-33.246 and 1.231-59.598, P<0.05), being male protected against MACE (OR=0.058,95%CI=0.014-0.236,P<0.05). Conclusions The prognosis of patients of CHD under-went PCI was good. After PCI,the risk factors of CHD such as smoking,hypertension ,overweight,ete should be un-der control to decrease the occurrence of MACE.

Objective To evaluate the perfusion parameters in different zone of placenta using CPS,to research placental blood perfusion of different zone. Methods A total of 60 pregnant rats were divided into 3groups, 15 day,17 day and 20 day of gestation with 20 animals in each group,the placenta was divided into the central zone and marginal zone. SonoVue was injected by tail vein of rat using CPS, the time-intensity curves of the central zone and marginal zone were drawn and perfusion paramcters were calculate by software ACQ and Sonoliver. Surface area densities of different zone of placental maternal blood space was measured with histoligical method,and using immunohistochemical marked the placenta vascular. Results Arrivel time(AT) and time-to-peak(TTP) of placenta central zone was earlier than marginal zone,the peak intensity(PI) of the central zone was higher than that of the marginal zone ( P ＜ 0.05). There was significant difference between the central zone and marginal zone of surface area densities of placental maternal blood space ( P ＜0.05). PI of the central zone and marginal zone and the surface area densites of placenta was positively correlated ( P ＜0.05). The placental blood vessels was not expressed by factor Ⅷ.Laminin in the placental basement membrane expression of 20 day of gestation was not continuous or missing. Conclusions The surface area densities of central zone and marginal zone was different. CPS technique can be sensitive to detect changes of the placenta vascular bed in different zone.

French hospital administrators have undergone several changes to meet the needs of economic and social development,resulting in the pattern of hospital administration by both the central government and regional organizations.This paper made descriptions and analysis of the French hospital administrators and came up with the following insights:Making public hospitals as the main health service provider benefits provision of public services; public and private hospitals can jointly meet public service needs under government regulation; the government should focus on controlling health care resources;medical service system needs an overall policy guidance; hospital management organizations should streamline in the reform.
