Objective To analyze the clinical and immunological manifestations of antiphospholipid syndrome(APS)in a cohort of 100 patients.Methods The clinical and serologic features of APS(Sapporo preliminary criteria)in 100 patients were analyzed retrospectively.Results The cohort consisted of 79 female patients and 21 male patients witb a mean age of 36?13 years at diagnosis.Primary APS was presented in 37% of patients;APS was secondary to systemic lupus erythematosus(SLE)in 46%,lupus-like syndrome in 14%. Eighty percent of the patients had thrombosis,43(54%)patients had venous thrombosis,18(22%)had arterial thrombosis,15(19%)had both arterial and venous thrombosis.4(5%)had thrombosis of microcirculation. Forty-two(52%)patients presented thrombosis at a single site,26(32%)at two sites,12(15%)at three or more sites.Forty-five(56%)patients experienced one thrombotic episode,20(25%)patients had only one re- currence,and 15(19%)had more thrombosis.The most common manifestations of thrombosis were deep vein thrombosis(36%),pulmonary embolism(30%)and stroke(26%),with heart,kidney,gastrointestinal tract and other organs involvements.Thirty-four(51%)female patients had spontaneous fetal losses including intrauter- ine fetus death and recurrent spontaneous abortion.Seventy-one(71%)patients developed thromboeytopenia. The presence of antieardiolipin antibody(ACL)was detected in 84 patients(84%).Among 90 patients with APS,alone ACL was detected in 38 patients(42%),both ACL and lupus anticoagulant(LA)were detected in 36(40%),LA alone in 16(18%).Patients with APS associated with SLE or lupus-like syndrome had higher frequency of arthritis,leukopenia,antinuclear antibodies(ANA)and low complement levels.Female patients had a higher frequency of leukopenia,ANA and ACL.Male patients had a higher prevalence of deep venous thrombosis in the lower limbs and LA.Conclusion APS is an autoimmune disorder characterized by recurrent arterial and venous thrombosis,fetal loss,or thrombocytopenia with the presence of ACL and/or LA.In APS secondary to with SLE,the patient's sex can modify the disease expression and define specific subsets of APS.

Objective To investigate the effect of hyperlipidemia on glomerulus podocyte injury with IgA nephropathy.Methods Fifty-one IgA nephropathy patients with biopsy-proven were selected.Immunohistochemistry was applied to detect the expression of WT1,a marker of podocyte,in the renal tissue of patients with IgA nephropathy.The density of podocyte per glomerulus wascalculated using specific software.Results Triglyceride (TG) was positively correlated with glomerulus podocyte injury,serumcreatinine and glomerulosclerosis in IgA nephropathy (r =0.549,0.770,0.698,P ＜ 0.05 or ＜ 0.01 ),and there was no correlation with 24 h proteinuria.The expression of WT1 was significantly decreased in glomerulus of patients with IgA nephropathy (P ＜ 0.01 ).There was no correlation between the expression of WT1 and 24 h proteinuria,but the expression of WT1 was positively correlated with serum creatinine and glomerulosclerosis (r =0.765,0.679,P ＜0.01).Conclusion Hyperlipidemia may induce glomerulus podocyte injury in IgA nephropathy,and it may contribute to the progression of IgA nephropathy.

Study a method for the detemination of the content of polysaccharides in Gentiana farreri, and analysis of the content of polysaccharides from different producing areas. The results showed that using the anthrone-sulfuric acid method, simple operation, accurate result. Sample was measured at 620 nm absorbance after anthrone-sulfuric acid color, at this wavelength, solution absorption and glucose showed a good linear relationship; The linearity was in the range of 0.01-0.07 g x L(-1) (r = 0.996 7). The recovery rate was 99.41%, with RSD of 2.0%. Considering the experimental conditions, to determine the solid-liquid ratio 1:60, extracting time 50 min, concentration of ethanol 80%. The mass fraction of polysaccharides was the highest to reached 0.743% in G. farreri from Gansu Xiahe. This experiment has laid a good foundation for further study on G. farreri.

Objective To investigate the usefulness of 99Tcm-MDP whole body bone scintigraphy (WBBS) in patients with synovitis,acne,pustulosis,hyperostosis,osteitis (SAPHO) syndrome.Methods 99Tcm- MDP WBBS was performed in 25 patients (6 males,19 females,mean age =(55.1 ±9.8) years)with SAPHO syndrome.Bone lesions were classified into five categories:anterior chest wall,spine,mandible,sacroiliac joint,and limbs.The typical scintigraphic manifestations of SAPHO syndrome were summarized and compared to other radiological imaging data.Results Among 25 patients,32％ of cases (8/25)were associated with skin lesion; 48％ ( 12/25 ) were pathologically diagnosed with chronic nonspecific bone inflammation by bone biopsy.On 99Tcm-MDP WBBS,abnormal metabolic foci at anterior chest wall were found in all cases,most of which located in the sternocostoclavicular region (96％,24/25 ),including sternoclavicular joints (60％,15/25),first costosternal junctions (48％,12/25),and manubriosternal junctions (44％,11/25 ).Only 20％ of the patients (5/25) demonstrated the typical scintigraphic characteristic:“bull's head” sign.The second most frequent part was spine (44％,11/25).Appendicular skeleton was affected in 16％ (4/25) patients.WBBS also demonstrated additional skeletal lesions in 68％ (17/25 ) of the patients,mainly in first costosternal junctions (7 patients),sternoclavicular joints (6 patients),manubriosternal junctions (5 patients) and spine (4 patients).Conclusions Abnormal metabolic foci in sternocostoclavicular region and other imaging manifestations on 99Tcm- MDP WBBS can be used to diagnose,differentiate,and localize the insidious lesion and evaluate the lesion activity in patients with SAPHO syndrome.

OBJECTIVETo explore the effects of hepatitis B immune globulin (HBIG) in prevention of mother-to-infant hepatitis B virus (HBV) transmission.

METHODA total of 279 pregnant women positive for HBsAg alone or for both HBsAg and HBeAg were enrolled into this study from January 2001 to May 2005. They were respectively divided into two groups at random, namely, only HBsAg-positiveexperimental group (n = 80), only HBsAg-positive control group (n = 60), both HBsAg and HBeAg-positive experimental group (n = 79) and both HBsAg and HBeAg-positive control group (n = 60). The two experimental groups were injected with HBIG once every four weeks until labor. The two control groups received no HBIG. The infants received intramuscular HBIG 16 hours after birth and two weeks later, in addition to routine immunization with hepatitis B vaccine. The infants were followed up and HBsAg was determined.

RESULTSThe HBsAg infection rates of babies in the four groups were respectively 3%, 13%, 10%, 32%. The infection rate of the infants whose mothers were injected with HBIG was significantly lower than that of the control group.

CONCLUSIONThe HBIG could effectively prevent HBV transmission from mothers to infants and reduce the HBV infection rate.
