On the basis of the Uncaria transcriptome, specific primers were designed for UrSTR. The full-length cDNA of UrSTR (GeneBank: OL310251) was 1 541 bp, encoding 345 amino acid residues, and the promoter region sequence of UrSTR (GeneBank: OL310252) was 1 179 bp. Phylogenetic tree is revealed that UrSTR had a closest relationship with STR from Ophiorrhiza pumila and Ophiorrhiza japonica. Localization of UrSTR protein is revealed located in the vacuole membrane. Plant-care analysis indicated that the promoter region sequence of UrSTR, covering multiple light, stress and hormone-response cis-regulatory elements, and verified transcriptional activity. The results of SDS-PAGE show that pET-28a-UrSTR recombinant protein was successfully expressed, and the size was anticipated. The UrSTR prokaryotic expression system needs to be optimized in the later stage. The research lays the foundation for further purification to study its structure and functional characterization of the UrSTR protein.

Aleutian mink disease parvovirus (AMDV) causes a persistent infection associated with immune complex disease, hypergammaglobulinemia, and high levels of antiviral antibodies. Despite the presence of an antibody, the virus is not cleared in vivo. Pre-existing antibodies may enhance viral infections, by Fc-receptor-mediated antibody-dependent enhancement (ADE), but the mechanism that underlies ADE has not been fully defined. Three models have been proposed, including: (1) interactions between antibody and FcR, complement C3 fragment and CR, or between C1q and C1qR, which promotes viral attachment to cells; (2) suppression of IFN-gamma-mediated host-cell antiviral gene expression by the upregulation of negative regulators of pathogen pattern recognition; and (3) the promotion of early IL-10 secretion. In addition, the role of cytokine IL-6 in ADE mediated disease development is discussed, to facilitate a better understanding of the pathogenesis of AMDV infection, as well as give insights into rational vaccine design approaches.

Chlorogenic acid displays several important roles in the therapeutic properties of many herbs, such as antioxidant activity, antibacterial, antiviral, scavenging free radicals and exciting central nervous system. Only about one-third of chlorogenic acid was absorbed in its prototype, therefore, its gut metabolites play a more important role in the therapeutic properties of chlorogenic acid. It is necessary to consider not only the bioactivities of chlorogenic acid but also its gut metabolites. This review focuses on the potential activities and mechanisms of chlorogenic acid and its gut metabolites on central nervous system diseases.

Objective To evaluate the effectiveness of arthroscope-assisted surgical technique in treating knee fractures and knee peripheral fractures.Methods From September 2000 to December 2005,there were 46 cases with knee or knee peripheral fractures,in whom artbroseope-assisted surgical technique was performed in 36 cases including 24 males and 12 females,with mean age of 30.5 years (18-52 years).Of 36 cases,26 cases with patella fractures were treated by internal fixation of tension band using cancellous bone screws,four with distal end femoral fractures by retrograde interlocking using intramedullary nail and six with fractures of tibial plateau and tibial condyle crista by internal fixation u- sing cancellous bone screws.Results The mean hospitalization was eight days.A follow up for 3-36 months(average 14 months)in 36 cases showed fracture healing.Of 36 cases,32 cases regained full knee range of motion,four left with terminal flexion,with mean loss of 15?,and had thigh circumference (10 cm above knee)1.1 cm(range 0.6-2.0 cm)shorter than health side and two had slight pain in the knee joint.Lysholm knee joint function score was 86.5+7.6 for patellar fractures,tibial plateau frac- tures and condylar crista fractures.Conclusion As for knee or knee peripheral fractures,arthroscope- assisted surgical technique can provide fine monitoring,decrease trauma and complications,fixate inter- nally and help early ground exercise.

AIM: To investigate the time - effect relationship between the expression of rhodopsin and recoverin and photoreceptor damage induced by N - nethl - N -nitrosourea ( MNU) .
METHODS: Thirty-six 7-week old Sprague-Dawley ( SD ) rats were intraperitoneally injected with MNU ( 60mg/kg ) and were put to death by dislocation of cervical vertebra 6, 12, 24h; 3, 7d after injection ( 6 per group) , respectively. As a control, six rats were injected with phosphate buffer saline (PBS) 5mL/kg and sacrificed on d3 after injection. The degree of photoreceptor apoptosis was detected by HE staining, terminal deoxynucleotidyl transferase-mediated dUTP nick end-labeling ( TUNEL ) and transmission electron microscope ( TEM ) in the right eyes. The mRNA expressions of rhodopsin and recoverin were detected different time after injection by Western blot and immunohistochemical method in the left eyes.
RESULTS:The dissolution of photoreceptor nucleus and apoptosis body were first perceived at 12h by TEM; most of cells at outer nuclear layer were presented positive reaction. The apoptotic index reached peak ( 29. 7% ±2.3%) at 24h which was coincided with the observation of TEM. The results of immunohistochemistry displayed that rhodopsin and recoverin were on a declining curve with time extension. Furthermore, the results of Western blot indicated that rhodopsin had dramatic decline at 6h after injection (P<0. 05), and extremely significant difference comparing to control group after 12h ( P<0. 01 ); while recoverin dramatic declined at 12h, and extremely significant difference after 24h (P<0. 01).
CONCLUSION:60mg/kg MNU intraperitoneally injection one - time may specifically induce photoreceptor apoptosis, The mechanism of down - regulation of rhodopsin and recoverin may be related to the selected apoptosis of photoreceptors.

Objective To analyze the pathological and clinical characteristics of patients with idiopathic IgA nephropathy accompanied by vasculitic/crescentic lesion (IgA-V/C). Methods Data of 222 patients diagnosed as idiopathic IgA nephropathy by renal biopsy, among them 87 cases with vasculitic/crescenlic (V/C)lesion, from our department in 2004 were analyzed retrospectively. Clinical and pathological data from patients with IgA-V/C were compared to those of non-IgA-V/C patients and of lupus nephritis (LN) patients with V/C lesion. Results Vasculitic/crescentic lesion was found in 39.19% (87/222) patients with idiopathic IgA nephropathy.And about( 14.08?12.75)% of the glomeruli was affected. It should be taken into account that there was no significant differences of clinical manifestations including blood pressure, urinary protein excretion between IgA-V/C group and non-IgA-V/C group .except serum creatinine(Scr)level which was significantly higher in IgA-V/C group. In addition, only 37.9% of IgA-V/C patients presented high Scr level,thus the lesion of V/C in idiopathic IgA nephropathy was easily overlooked. Patients with idiopathic IgA nephropathy were found to have higher percentage of glomerular sclerosis (64.86% vs 40.00%) and ratio of sclerostic glomeruli to total glomeruli [ (26.98 ?24.68)% vs (16.10 ?18.80)% ]as compared to LN group, which further predicated the progressing characteristics of IgA nephropathy. Conclusions Vasculitic/crescentic lesion is a quite common finding in idiopathic IgA nephropathy and often associated with no dramatically symptoms. It is possible for vasculitic/crescentic lesion to induce unmarked lose of nephron slowly and continually, so as to accelerate IgA nephropathy progression to end-stage renal failure.

Objective To investigate the prevalence of mite sensitivity in patients with urticaria or other skin rashes, and to observe the clinical efficacy of a specific immunotherapy(SIT) by the Injectio dermatophagoidei farinae for the patients.Methods In 7-year period(1998-2005), skin prick test(SPT) with a dust mite(Df) allergen was carried out to detect the prevalence of mite sensitivity in OPD patients suffering from skin rashes.Among the patients sensitive to mite with SPT ≥++ response, 3 groups were established.In group A, routine SIT with Injectio dermatophagoidei farinae was conducted.In 9-week increasing dose phase, three stepwise increasing volumes(0.3ml, 0.6 ml and 1.0 ml) each case was injected subcutaneously with mite concentration of 1 ∶ 100 000(w/v) , 1 ∶ 10 000(w/v) or 1 ∶ 5 000(w/v) respectively once a week, followed by a maintenance dose phase for an injection with 1 ∶ 5 000(w/v) 1.0 ml/wk for 6 weeks.Group B received rush SIT with mite injections.A total of 15 injections in a course of therapy with same concentration and volume was given as those for the routine ones except shortened intervals, namely, 9 initial injections completed in 3 days by three injections of each concentration per day with two 30 min intervals, maintenancedoses were then provided in 6 days with 1 ∶ 5 000(w/v) 1.0 ml/d.Thereafter, both groups A and B were maintained for one year with a dose of 1 ∶ 5 000(w/v) 1.0 ml every 2 wk.Group C received antihistamine treatment as control, the patients received daily oral Ebastine 10 mg in the morning and Cetirizine dihydrochloride 10 mg in the evening for one week course and pro re nata later.Levels of serum tIgE and serum mite sIgE were detected by ELISA in 20 urticaria cases before and after one year mite SIT.Results Altogether, 2 685 cases with skin rashes were detected by Df allergen SPT.The prevalence of urticaria cases sensitive to mite was 70.3%(1 754/2 496), which was higher than that of eczema 63.5%(54/85) and anaphylactoid purpura 60.6%(63/104)(P
