Observe and study the morphological changes and effects on yoleperoxidase (MPO) of traditional Chinese medical complex Intestine-clearing Suppository (ICS) in preventing and treating ulcerative colitis (UC).Method.. Divide the experimental rats randomly into 6 groups, i.e., blank, salicylazosulfapyridine (SASP), model, high, middle and low dosage of ICS, except the blank group, makeother rats experimental UC model with albumen immunologic method of rabbit colon mucosa, further divide them randomly into 2 experimental groups, i. e. , prevention and treatment, afterwards at 2nd~21st day, give prevention group the medicine, 22nd~35th day, treatment group, then decapitate them and take the colon tissue, and observe it morphologically under optical microscope, measure active MPO, analyse statastic results. Result: Through general morphological observation ,we found there were serious congestion ,edema, mucosa erosion, many large ulcers in the rats of model group; less serious mucosa erosion and quantity of ulcers in SASP and low-dosage ICS groups: small ulcers, not serious mucosa erosion, low degree of congestion and edema in high-and middle-dosage ICS groups; the scores of inflammatory injury of ICS groups were markedly lower than that of model (P＜0. 01), meanwhile, the preventive and reating effectiveness of high-and middle-dosage groups was better than that of SASP (P＜0.05). Under the optical microscope, there were large area of mucosa coloboma in the rats of model group, the ulcer penetrated to muscular layer and serous coat; in SASP group and low-dosage ICS group, there were erosive mucosa and inflammatory cell infiltration, granulation on the base; in middle-and high-dosage groups, large part of colon mucosa recovered, granulation formed on the base, ulcers were obviously less than that in model group (P <＜0.01); there had marked difference compared with that in SASP group (P＜0.05). The MPO active values of high-and middle-dosage groups were markedly lower than that of model group (P ＜ 0.01). Conclusion: Traditional Chinese complex ICS had good prevention and treatment to rats UC, itseffectiveness was positively correlated with dosage and better than that of SASP suppository.

Ocular albinism type 1 (OA1),the most form of the ocular albinism,is an X-linked disorder mainly characterized by a severe reduction of visual acuity,hypopigmentation of the retina,photophobia,strabismus and nystagmus. The OA1 gene is located on chromosome Xp22.32 and the coding sequence is divided into nine exons. The OA1 gene codes for a 404 amino acid protein thought to be a melanosomal transmembrane glycoprotein. The OA1 protein is similar to the G protein-coupled receptors,but it's exact function is not clear. There are many mutations and deletions of the OA1 gene have been found.

Objective To develop a rapid method based on ARMS, named four primers allele-specific PCR(4p-AS PCR), to detect the most common non-deletional ?-thalassemia mutation Hb Constant Spring(Hb CS) by PCR technique. Methods The 4p-ASPCR was used to detect the Hb CS mutation of ?-thalassemia in 38 DNA samples of Hb H disease patients and using PCR-RE and DNA sequencing to confirm the results. Results Among the 38 Hb H disease patients 15 cases was revealed to carry Hb CS, 16 cases were deletional Hb H, and 7 cases need to be defined.Conclusion A simple, rapid and reliable method, named 4P-ASPCR, to detect Hb CS mutation have been developed. It is also may be useful in screen other point mutations such as Hb Quong Sze.

METHODS: The rat model of endometriosis was established, and the expression of ER, PR mRNA in the endometrium was examined by reverse transcription-polymerase chain reaction (RT-PCR). RESULTS: The expression of ER and PR mRNA in ectopic endometrium was significantly lower than that in eutopic and normal endometrium (P

Objective To evaluate the clinical outcome of Vancouver B2 and B3 periprosthetic femoral fractures treated with uncemented modular stems.Methods From September 2011 to April 2014,Twenty-four patients (12 males and 12 females,with the average age 63 years,ranging from 28 to 85 years) with periprosthetic femoral fractures (16 Vancouver B2 and 8 Vancouver B3) were treated with uncemented modular stems.Revision arthroplasty was conducted in all cases by using modular stems with 12 cerclage wirings and 11 great trochanter claw plates.One patient was treated with revision arthroplasty without additional fixations.Extended trochanter osteotomy was performed on 11 patients.Cortical strut allograft was used in 9 patients with severe femoral bone loss.Intraoperative complications including vascular or nerve injury and systemic complications including cardiovascular events,cerebrovascular events and deep vein thrombosis were recorded.Severe postoperative complications such as nonunion,re-fracture,periprosthetic joint infection and dislocation were recorded.The clinical outcome was evaluated by Harris score,Visual Analogue Score and Parker Mobility Score.The radiological outcome was taken to observe the healing status,stem subsidence and stability of the prosthesis.Results Two patients were lost to follow-up.Twenty-two patients were clinically followed-up.Radiological data was recorded in 16 patients.The average follow-up was 33 months (range,12-68 months).All fractures healed within 6 months.The average Harris score improved from 4.0± 1.1 preoperatively to 78.8± 16.2 postoperatively (t=-20.195,P=0.000).The mean Parker Mobility Score improved from 0.5±0.9 preoperatively to 7.0± 1.8 postoperatively (t=-14.835,P=0.000).The mean Visual Analogue Score decreased from 6.4± 1.2 preoperatively to 2.0± 1.5 postoperatively (t=10.879,P=0.000).No nonunion,infection or dislocation was found.One patient underwent re-operation because of re-fracture.Eight mm of prosthesis subsidence was observed in one case at 3 months postoperatively,and reached stable fixation at 6 months postoperatively without further subsidence.Conclusion Uncemented modular stems can achieve distal fixation and implant stability of periprosthetic femoral fractures while retaining optimal biomechanics of the hip.Assisted by femoral reconstruction techniques such as extended trochanter osteotomy,cortical strut allograft,great trochanter claw plates and cerclage wiring,revision arthroplasty using uncemented modular stems could realize optimal outcomes in treating Vancouver B2 and B3 periprosthetic femoral fractures.

ObjectiveTo investigate the role of SAA in rheumatoid arthritis(RA) pathogenesis by analyzing the expression of serum amyloid protein A(SAA) in serum,synovial fluid and synovial membrane in patients with RA.MethodsSAA levels in the serum and synovial fluid in each group were detected.Sera SAA was tested by Western blotting,while the expression of SAA in RA and osteoarthritis(OA) synovium was detected by immunohistochemistry.Comparisons between groups were performed by t-tests or KruskaWallis test.ResultsThe serum levels of SAA were significantly higher in RA [(318±132) μg/L] than those in OA [(127±47) μg/L] and healey controls [(127±41) μg/L,P＜0.01].In RA,the SAA levels in the synovial fluid [ (571±473) μg/L ] were significantly higher when compared to those in O A [ (129±33) μg/L](t=2.46,P=0.04).Western blotting results showed that SAA bands were found in the serum samples of each group,and higher expression of SAA were seen in RA.Pathology study had showed that SAA was observed mainly in endothelial cells,synovial fibroblasts,macrophages and perivascular areas in RA synovium.In OA,SAA was observed in perivascular areas and synovial fibroblasts.ConclusionIn RA,SAA levels in both serum and synovial fluid are significantly higher than those in the controls.High expression of SAA in RA synovium can be observed.Our results suggest that SAA may play a role in inflammation reaction and joint destruction of RA.

Objective To observe the effect of Xiaochaihu decoction(XCD) on experimental endometriosis in rats.Methods Rat models of endometriosis were established and the effect of XCD were evaluated by measuring the volume of ectopic endometrium (EE) and its ultrastructure with transmission electron microscopy.Results After treatment,moderate and high-dosage of XCD(10g/kg and 15g/kg respectively) could markedly inhibit endometrial explant growth and decrease the volume of EE(P 0.05).Meanwhile,the glandular cells in the endometrium after treatment in the moderate and high-dosage groups showed characteristic features of apoptosis:cellular atrophy,condensation of cytoplasm and nuclear chromatin and increase of their density,occurrence of the intercellular apoptotic bodies as well as degeneration and necrosis of stromal cell.Conclusion XCD has obvious effects in inhibiting ectopic endometrium and its mechanism may be related to the reduction of cell death (including apoptosis and necrosis) by regulating the immune function.

AIM and METHODS:The purpose of the study was to characterize the time-related effect of Danazol therapy on endometriosis explant using the rat model. Endometriosis was induced in mature female rats. One group of treated animals as well as controls were sacrificed at 2,4,6 and 8 weeks after treatment at which time the explant was evaluated. RESULTS:Explant volume was significantly reduced in all treatment groups, and the effect was more significant in animals treated for 4 weeks than those treated for only 2 weeks. CONCLUSION:Danazol treatment can cause gradual regression of endometrial explant in a time-related manner.
