Objective To study the effects of mifepristone on fetus liver and kidney in the management of second-trimester pregnancy. Methods We selected 16 of the second-trimester pregnant (1 6 to 22 weeks) women who requested termination of pregnancy, and divided them in to two groups. In the mifepristone group (n=8), each woman received 150 mg mifepristone orally (separated to 25 mg, twice per day), following which prosta glandin (600 ?g) was orally administered on the fourth morning. The contro l group (n=8) was induced labor with water bag. After the fetal disengagemen t, immediate anatomization was performed on the fetus and 4 small pieces of live r and kidney tissues were obtained. Then the samples for electron microscope wer e prepared and observed. Results Compared with the control group, liver and kidney u ltrastructure in the mifepristone group showed extensive pathological changes. Conclusion Termination of pregnancy with mifepristone can d amage the liver and kidney of fetus, so it will be not suitable to continue preg nancy after unsuccessful induced labor by mifepristone in the second-trimester pregnancy. Mifepristone should be carefully used to end the mature pregnancy.

AIM:To investigate the effect and safety of intravitreous injection of conbercept ( 0. 5mg ) on macular edema secondary to central retinal vein occlusion ( CRVO) . ·METHODS: According to the selective criteria, from October 2014 to October 2015, 48 cases ( 48 eyes ) of patients with macular edema secondary to CRVO were collected, which were divided randomly into conbercept group ( 24 cases, 24 eyes ) and control group ( triamcinolone acetonide 4mg/0. 1mL, 24 cases , 24 eyes ) . The best-corrected visual acuity ( BCVA ) , intraocular pressure, intravitreous injection, fundus oculi, central macular thickness ( CMT ) and related complications were observed before and 1wk, 1, 3, 6 and 12mo after intravitreous injection. · RESULTS: There was no difference on BCVA, intraocular pressure, intravitreous injection, fundus oculi and CMT between the two groups before operations ( P>0.05). There were no significant differences (P>0.05) of the BCVA between two groups after treatment for 1wk, 1, 3, 6 and 12mo. Before and after treatment, the decrease of CMT in conbercept group was respectively 130. 17 ± 1. 72μm, 253. 33 ±3. 14μm, 318. 00±1. 41μm, 20. 01±1. 21μm and 15. 09 ± 1. 41μm, and no related complications.

Toll-like receptors (TLRs) family may play important roles in inflammatory bowel disease. This study examined the expression of TLR2, TLR4 and TLR9 in the colonic tissues of patients with ulcerative colitis (UC) and explored their roles in the pathogenesis of UC. Colonic biopsies were taken from the colon of 30 patients with mild or moderate UC (at active phase) and 10 healthy controls during colonoscopy. TLR2, TLR4 and TLR9 protein expression levels were immunohistochemically detected. The mRNA expression levels of TLR2, TLR4 and TLR9 were assessed by reverse transcription polymerase chain reaction (RT-PCR). The disease activity index (DAI), colonoscopic and histologic grades and fecal microbial flora were determined. Histological examination showed that the intestinal mucous membrane of UC patients underwent acute inflammation changes. Immunohistochemistry exhibited that the expression levels of TLR2, TLR4 and TLR9 in colon epithelia and inflammatory cells were higher in UC patients than in control group (P<0.01). The mRNA expression levels of TLR2, TLR4 and TLR9 were increased in UC patients but were not detected in the normal controls. Expression levels of TLR2, TLR4 and TLR9 were positively correlated, and bore close correlation with DAI, colonoscopic and histologic grades and fecal microbial flora. An important mechanism of UC might be that abnormal activation of mucosal immunity by intestinal dysbacteriosis caused dysregulation of TLRS that mediates innate immunity.

Objective To investigate the relationship between glucokinase regulator protein ( GCKR) gene polymorphism rs780094 and hyperuricemia in Uygur in Xinjiang. Methods A case-control study including 1 026 patients with hyperuricemia and 1 030 normal subjects was conducted. All the subjects were genotyped for GCKR gene rs780094 by Sequenom MassARRAY system. The results of rs780094 genotype and allele frequency between hyperuricemia group and control group were compared. The associations of different genotypes of rs780094 with blood pressure, blood lipid, and blood glucose were analyzed. Logistic regression analysis was used to analyse the relationship between polymorphism of rs780094 and hyperuricemia in Uygur in Xinjiang. Results The distributions of three genotypes(G/G, A/G, A/A) and two allele frequency (G and A) in GCKR rs780094 revealed statistical difference ( P<0. 05 ) between hyperuricemia group and control group. A tendency toward association with hyperuricemia was observed under dominant model(OR=1. 295, 95%CI 1. 078~1. 554,P=0. 006) and recessive model(OR=1. 284, 95% CI 1. 024 ~1. 611,P=0. 030). The levels of systolic blood pressure, diastolic blood pressure, and total cholesterol were lower in hyperuricemia group with GCKR gene rs780094 loci GG genotype than those with AA+AG genotype. After adjusting confounding factors which had significant difference in the single factor analysis, logistic regression analysis showed that rs780094 A/A and A/G might be risk factors of hyperuricemia in Uygur in Xinjiang (OR=1. 355,95% CI 1. 094 ~1. 679,P=0. 005). Conclusion The GCKR rs780094 is associated with hyperuricemia in Uygur in Xinjiang. The A/A and A/G genotype of the GCKR rs780094 may increase the risk of hyperuricemia.

Objective To understand the clinical features of Behcet′s Disease( BD) with pulmonary hypertension( PH) .Methods The etiology, clinical features, treatment and prognosis of 25 patients with Bahcet′s disease ( BD) complicated with pulmonary hypertension ( PH) admitted in Peking Union Medical College Hospital from January 2000 to August 2015 were retrospectively reviewed.Results Total 912 BD patients were hospitalized during the same period, among whom 25 cases were complicated with PH accounting for 3%.There were 15 males (60%) and 10 females (40%), with the mean age of (33 ±12) years (range 19 to 66 years).The median interval from the diagnosis of BD to the onset of PH was 1 year (range 0 to 40 years).The most common cause of PH was heart valve disease (n=10, 40%), followed by pulmonary arterial stenosis or occlusion (n=6, 24%), pulmonary arterial aneurysm with thrombus (n=1, 4%), pulmonary thrombosis (n=1, 4%), cardiomyopathy (n=1, 4%);there were no causes identified in 6 cases (24%).Pulmonary arterial pressures estimated by echocardiography were 40 to 117 mmHg (1 mmHg=0.133 kPa) with a mean pressure of (60 ±22) mmHg.When the PH developed, elevated erythrocyte sedimentation rate ( ESR ) and increased hypersensitive C-reactive protein ( hs-CRP ) were founded in 48% ( 11/23 ) and 82% ( 14/17 ) of patients, respectively.After treated with glucocorticoid (96%,24/25), immunosuppressive agents(92%, 23/25), anticoagulation or thrombolysis(36%,9/25) and specific targeted vasodilator(32%,8/25), the levels of ESR and hs-CRP declined in 91% (10/11) and 71%(10/14) of patients, respectively; and pulmonary arterial systolic pressure declined in 50% of cases (8/16).Among 9 patients followed for 2 to 96 months, 4 died, 1 aggravated, 2 kept stable and 1 improved.Conclusion PH is an uncommon complication in disease.Heart valve disease, pulmonary artery involvement are the major causes of PH.The therapeutic effect and prognosis are poor.

OBJECTIVETo investigate the expression of extracellular matrix metalloproteinase induced (EMMPRIN) in the interface tissue, and explore the role of EMMPRIN in the aseptic loosening of prostheses.

METHODSImmunohistochemistry was performed to characterize the EMMPRIN-expressing cells at sites of interface tissue around aseptic loosened hip prostheses in 16 cases. Reverse transcription-polymerase chain reaction (RT-PCR) was performed to study the existence of EMMPRIN mRNA in interface tissue samples. And it was followed up by computer assisted image analysis in order to detect the A values of their expression. Synovium of hip joint of 8 femoral neck fracture were in control group.

RESULTSStrong immunostaining of EMMPRIN was found in the macrophages and fibroblasts of lining-like layers and vascular endothelium of synovial membrane-like interface tissue around loosened prostheses. Expression of EMMPRIN was significantly higher in interface tissue than the control synovium (z=-3.252, P=0.001). RT-PCR of interface tissue samples disclosed the presence of EMMPRIN mRNA of 14 cases. In interface tissue, the A value of EMMPRIN increased significantly compared to control synovium (P<0.01).

CONCLUSIONOver-expression of EMMPRIN up-regulates the production of matrix metalloproteinase (MMPs) in the interface tissue. And it can promote the bone destruction around prostheses. Thereby it may be one of methods to prevent and treat aseptic loosening of prostheses by repression the biology activity of EMMPRIN.

The effects of the concentration of sulfuric acid and the ratio of liquid to solid on xylose yield from sugar cane bagasse in its hemicellulose hydrolysis process were studied with the Quadratic Rotary Combination Design. Regression analysis showed that there was a marked regression relationship between the two factors and xylose yield. As the result of optimizing the hydrolysis conditions by regression equation, xylose yield of 24 g/100 g sugar cane bagasse was obtained when sulfuric acid concentration was 2.4 g/L and liquid to solid ratio was 6.2 under the conditions of stream pressure of 2.5 x 10(4) Pa and hydrolysis time of 2.5 h. The macroporous resin adsorption was proved to be a good method to reduce the concentration of yeast cell growth inhibitor in sugar cane bagasse hemicellulose hydrolysate and to enhance the hydrolysate fermentability. The hydrolysate treated with macroporous resin adsorption under pH2 was used as the substrate for xylitol production by a xylitol-producting yeast, Candida tropicalis AS2.1776. At an initial xylose concentration of 200 g/L, all xylose was consumed within 110 h with a xylitol production rate of 1.15 g/L.h, and a xylitol yield of 0.64 g/g xylose.
