ABSTRACT
Idiopathic systemic capillary leak syndrome (ISCLS) is a rare disease, the clinical manifestation is increased acute episodic capillary leakage (SCL), leading to protein-rich fluid leakage from the blood vessels to the interstitial tissue space, resulting in progressive systemic edema, hypoproteinemia, hypotension, blood concentration and other clinical symptoms. Because of ISCLS frequent recurrences, high mortality, pathogenesis unclear and no definite treatment plan, it is extremely important to fully understand the disease to carry out early intervention to save the patients' lives. This article reviews the progress of ISCLS, including its disease onset characteristics, clinical features, pathological mechanism, diagnosis and treatment of ISCLS.
ABSTRACT
Objective To analyse the clinicopathological characteristics of synovial sarcoma (SS) from histomorphology,immunohistochemical (IHC) and fluorescence in situ hybridization (FISH),and to investigate the related factors influencing the prognosis of SS patients.Methods 94 cases were collected,including 60 SS cases and 34 in dined to SS cases.The expressions of common antibodies related to the diagnosis of SS Vimentin,CD99,AE1/AE3,EMA,CD34,Calponin,Ki-67 were detected by IHC,and the SYT-SSX fusion gene was detected by FISH.The clinical pathologic factors that affecting the prognosis of patients were analyzed through the statistical method.Results The positive rates of Vimentin,CD99,AE1/AE3,EMA,CD34,Calponin,Ki-67 were 100.00 ％,74.47 ％,36.17 ％,28.72 ％,17.02 ％,90.43 ％ and 60.64 ％ respectively.FISH results showed that 81 patients were tested with SYT gene translocation,including 54 cases who were considered as SS,and 27 cases who were suspected/inclined to SS,and the number of positive cells surpassed 80 ％.The gene translocation was not related with the patient' s age,sex,tumor position,histological type,differentiation of the cancer (all P ＞ 0.05).Single factor survival analysis showed that the degree of differentiation,tumor diameter,the recurrence and metastasis had certain influences on patients' survival time (all P ＜ 0.05).Multiple factors regression analysis showed that the degree of differentiation and tumor diameter were the risk factors influencing the prognosis of SS (risk coefficients ＞ 1,P ＜ 0.05).Conclusions IHC combined with FISH SYT-SSX fusion gene detection have the vital significance in the diagnosis of SS.The degree of differentiation and tumor size are the risk factors influencing the prognosis of SS.

ABSTRACT
Purpose To ana1yze the expression features of 5-F1uorouraci1(5-FU)metabo1ic enzyme thymidy1ate synthetase(TS),thy-midine phosphory1ase( TP),dihydropyrimidine dehydrogenase( DPD)and its re1ationship with c1inicopatho1ogica1 factors and progno-sis in co1orecta1 cancer,in order to further exp1ore its potentia1 significance in guiding co1orecta1 cancer chemotherapy. Methods Es-tab1ishment of a tissue microarray containing 72 patients with co1orecta1 cancer,and 56 norma1 tissue( dista1 cut edge tissue near carci-noma)was used to detect TS,TP,and DPD by immunohistochemistry,and to ana1yze its re1ationship with c1inicopatho1ogica1 factors and prognosis of co1orecta1 cancer through statistica1 method. Results The expression of TS in co1orecta1 cancer was 1ower than that in norma1 tissue(P=0. 876),which was associated with TNM(P=0. 043)and positive1y corre1ated with patients’overa11 surviva1(P=0. 027),the expression of TP in co1orecta1 cancer was higher than that in norma1 tissue(P=0. 315)that was associated with 1ymph node metastasis(P=0. 009)and negative1y corre1ated with the prognosis of patients(P=0. 040),DPD expression in co1orecta1 canc-er was higher than that in norma1 tissue(P=0. 071),which was re1ated to the histo1ogic type(P=0. 029). Overa11 surviva1 was sig-nificant1y shortened in co1orecta1 cancer with DPD high expression( P=0. 011). Conclusions TS,TP and DPD might be app1ied as important index of prognosis in co1orecta1 cancer patients using 5-FU adjuvant chemotherapy. The expression of TS re1ated c1ose1y with the c1inica1 stage is a bio1ogica1 marker of tumor progression. TP expression is c1ose1y re1ated to 1ymph nodes metastasis and recur-rence,which is an important factor of postoperative recurrence and metastasis.

DESIGN: Randomized and controlled observation SETTING: Department of Rheumatology , Guangdong Hospital of Traditional Chinese Medicine PARTICIPANTS: Totally 80 inpatients with ankylosing spondylitis hospitalized in the Clinic of Department of Rheumatology, Guangdong Hospital of Traditional Chinese Medicine from June 2003 to April 2004 were involved. The patients were randomly divided into 2 groups with 40 patients in each group. Informed consent was obtained. METHODS: Experimental group: 2 capsules of total glucosides of peony was taken orally, three times per day; methotrexate 10 mg/time, once per week; sulfasalazine 0.5 g/time, three times per day. Control group:methotrexate and sulfasalazine were taken orally and the dosage and method were the same as those in the experimental group. Two groups all used the same NSAID (Nimesulide) , 0.1 g/time, twice per day. The period of the treatment was 3 months. Evaluation of spinal column function and laboratory examination was performed before treatment and 4, 8 and 12 weeks after treatment. MAIN OUTCOME MEASURES: Primary outcomes: Bath ankylosing spondylitis activity index, Bath ankylosing spondylitis function index [1-2],duration of morning stiffness, systemic pain and spinal pain on a four point Likert scale, overall assessment of patient and physician on a four point scale. Secondary outcomes: ①erythrocyte sedimentation, C-reaction protein,Schober test, chest expansion, Occiput to wall distance and finger to floor distance.② Adverse events and side effects. RESULTS: The observation of 38 patients in the experiemtnal group and 37 patients in the control group was completed. ①Result of Bath ankylosing spondylitis activity index, Bath ankylosing spondylitis function index,duration of morning stiffness, pain and spinal pain on a four point Likert scale, overall assessment of patient and physician on a four point scale:The indices at week 4, 8 and 12 werevmore significantly decreased than those before treatment in each group (P ＜ 0.05); the Bath ankylosing spondylitis activity index, pain and spinal pain on a four point Likert scale,overall assessment of patient and physician on a four point scale at week 4and all the indices at week 8 and 12 were more significantly decreased than those in the control group (P ＜ 0.05). ② Evaluation result of Erythrocyte sedimentation rate (ESR) and C reaction protein, Schober test, chest expansion , occiput to wall distance and finger to floor distance: Each index at week 4, 8 and 12 in the experimental group were significantly decreased than those before treatment (P ＜ 0.05), those at week 8 and 12 in the control group were more significantly decreased than those before treatment (P ＜ 0.05). ESR , C reactive protein (CRP) , chest expansion and finger to floor distance at week 12 in the control group were more significantly decreased . ③ Adverse events and side effects: All adverse reactions occurred transiently during the course of disease in the two groups. Undisposed or after having taken live-protective medicine, all patients recovered.Drug was not withdrawn in any case.The incidence of adverse reaction in the experimental group was lower than that in the control group [10％ (3/30),57％(17/30) ,P ＜ 0.05]. CONCLUSION: Combination of total glucosides of paeony, methotrexate and sulfasalazine has an enhanced effect and better safety without special adverse reaction in the treatment of ankylosing spondylitis.
