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.

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 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.

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.

Objective:To analyze ultrasonic and clinical manifestation of noncompaction of the ventricular myocardi‐um (NVM) in order to guide clinical early diagnosis and treatment .Methods :Echocardiographic manifestations of 36 NVM patients were observed .Combined with electrocardiogram (ECG) ,cardiac MRI and coronary angiography (CAG) etc .,clinical manifestations of NVM were comprehensively analyzed .Results:Multiple coarse trabecular muscles and deep crypts among them were founded in heart chamber in all cases .Color Doppler showed that blood flow inside the crypts communicated with blood flow in heart chamber ,there were 33 cases (91.6% ) of left ventri‐cle type and three cases (8.4% ) of right ventricle type .Different types of abnormal ECG existed in all cases and at‐rial fibrillation occupied the largest proportion (50% ,18/36) .Some MRI results were accorded with those of ultra‐sound .In most cases ,CAG didn′t show coronary stenosis .Conclusion : Echocardiography is most convenient and effective examination ,which can provide important basis for diagnosis and treatment of noncompaction of ventricular myocardium .

Objective To quantitatively measure the perfusion parameters of placenta in different stage of pregnant rats using contrast-enhanced ultrasonography (CEUS) with contrast pulsed sequencing (CPS), and to analyze the relationship between perfusion parameters and changes of placental vascular bed. Methods Sixty healthy pregnant rats in according to the requirements of the experiment was divided into three groups: 15 days, 17 days and 20 days of gestation with 20 animals in each group. One blous injection of SonoVue (Sonovue 1.0 ml/kg) via a tail vein was administered to each rat, and the time-intensity curves (TIC) of placenta and uterine muscle wall were drawn with ACQ using CPS technique with MI 0.20, and the perfusion parameters were calculated. Then 4 μm vertical placenta sections were cut and stained with hematoxylin and eosin. Surface area densities of placental maternal blood space was measured with image analysis software. Results The peak intensity (PI) of 17 days and 20 days was higher than that of 15 days pregnant rats (P＜0.05). There was no difference in PI between 17 days and 20 days (P＞0.05), and nor of arrivel time (AT) and time-to-peak (TTP) (P＞0.05) among the three groups. There was significant difference of surface area densities of placental maternal blood space among the three groups (P＜0.05). PI was positively correlated to the surface area densites of placenta (P＜0.05). Conclusion There is close relationship between peak intensity and area densities of placental maternal blood space. CPS technique can sensitivly detect changes of the placenta vascular bed in different stage of pregnant rats.
