Objective To study the role of CXC chemokine receptor 5 (CXCR5) in the pathogenesis of bullous pemphigoid (BP) by detecting the expression of CXCR5 on follicular helper T (Tfh) cells in skin lesions of BP.Methods An immunohistochemical procedure was used to detect CXCR5 expression in biopsy specimens from skin lesions of 16 patients with BP and normal skin of 10 healthy individuals.Results CXCR5 was mainly expressed in the cytoplasm and membrane of Tfh cells in the basal cell layer of normal skin as well as in both basal cell layer and prickle cell layer of BP lesions.The number of CXCR5-positive ceils per high power field (× 400) was 11.16 ± 4.47 in normal skin specimens,significantly lower than that in lesional skin specimens (35.70 ± 12.20,t =6.07,P ＜ 0.01).Conclusion CXCR5 may be involved in the pathogenesis of BP.

OBJECTIVE To explore the clinical distribution and drug resistance of extended-spectrum ?-lactamases(ESBLs) producing Enterobacter cloacae.METHODS The clinical distribution and drug resistance of 73 strains of E.cloacae and ESBLs producing E.cloacae identified in our hospital from Jan 2002 to Jan 2004 were analyzed.RESULTS Among them,the highest detectable rate was in respiratory department and from phlegm specimen.No ESBLs producing E.cloacae and non-(ESBLs) were resistant to imipenem;no non-ESBLs were resistant to cefepime,but some ESBLs producing E.cloacae was resistant to it;all ESBLs producing E.cloacae and non-(ESBLs) were resistant to ceftriaxone and amoxicillin/clavulanic acid.CONCLUSIONS E.cloacae is one of the(commonest) pathogens in nosocomial infection,and ESBLs producing E.cloacae has a high detectable rate,its drug resistance has increased;the clinic should choose antimicrobial agents rationally according to drug sensitive tests in vitro.

Objective:To investigate the effect of the new nanomaterials,polyamidoamine dendrimers PAMAM-D,mediated foreign gene human decay accelerating factor(hDAF) for xenotransplantation transfected pig sperm cells.Methods:PAMAM-D/hDAF cDNA compounds were made.The compounds were divided into 0.2 μg,0.4μg,0.6μg,0.8 μg and 1.0μg groups (each group adding corresponding dose of PAMAM-D in accordance with the N/P ratio 10:1,20:1,40:1),then were digested by restriction enzymes.The compounds were incubated with washed pig sperm cells.Then the transfection efficiency was detected by in situ hybridization in the different groups.Results:The PAMAM-D molecule can prevent electrophoretic migration of DNA in the compound.After digested the compounds by restriction enzymes,DNA can not be degraded.The transfection efficiency was different in different groups.Among the total,the efficiency was higher in both groups of 0.4 μg and 0.6μg than that of others.The top was the group of 0.4 μg linear plasmid plus PAMAM-D when the N/P ratio was 20:1(47.5%±O.2%,167% vs control group).Conclusion:PAMAM-D can improve the efficiency of exogenous gene transfeeted pig sperm cells,which can reinforce the stable binding of exogenous DNA to sperm cells.

To develop simple, rapid, and efficacious diagnostic methods for malaria is one of the remaining key tasks for malaria control. Previously, we have created a phage-displayed antibody library against Plasmodium falciparum. Six clones of antibody with good reactivity to HRP-II in ELISA were isolated from the library after 3 rounds of enrichment. Soluble ScFvs were produced and the characteristics were determined. The results of Western blot showed that they could bind to HRP-II specifically and had a relative molecular mass(Mr) about 31 000. The work provided a solid fund for diagnostic kit development for malaria.

Objective To analyze temporal and kinematic parameters of video fluoroscopic images of swallowing using a digital acquisition and analysis system and to verify the reliability of this method.Methods Eighteen patients with dysphagia were requested to completed six swallows (3 ml and 5 ml of thin liquid, thick liquid, and paste mixed with 600 kg/m3 barium sulfate suspension) in the natural sitting position.Video fluoroscopy was used to measure the oral transit times, soft palate elevation times, hyoid movement times, laryngeal closure times, cricopharyngeal muscle opening times, hyoid anterior movement (HAM) , hyoid superior movement (HSM) , cricopharyngeal muscle opening diameter and pharyngeal constriction rate.Each was extracted from the videos four times by two raters working separately with an interval of 4 weeks between the sets of evaluations.Results Reliability varied among the different observations.HAM and HSM showed inter-rater reliability between 0.41 and 0.60 and intra-rater reliability between 0.61 and 0.80.The other observations all demonstrated acceptable reliability.Conclusion The self-designed digital acquisition and analysis system tested showed acceptable reliability and could be applied to analyze swallowing function clinically.

Rotator cuff disease and degenerative osteoarthritis are caused by many factors. Several studies had shown that rotator cuff disease was related to lateral extension of the acromion and glenoid inclination. A new parameter, critical shoulder angle (CSA), which is defined as the angle between a line connecting the superior to the inferior margins of the glenoid and a line connecting the inferior margin of the glenoid to the inferolateral edge of the acromion measured on anteroposterior (AP) shoulder radiographs, is proposed to comprehensively reflect the relationship between abnormal anatomical structure and rotator cuff injury. There is a close relationship between CSA and the injury of rotator cuff and the osteoarthritis of glenohumeral joint: the injury of rotator cuff is often accompanied by a larger CSA (> 35 °), and a smaller CSA (< 30 °) is closely related to the occurrence of glenohumeral arthritis. Therefore, CSA is helpful for the diagnosis of rotator cuff injury and glenohumeral osteoarthritis. Correction of abnormal CSA by arthroscopic lateral acromial osteotomy also provides a new idea for the treatment of shoulder diseases. In this paper, we reviewed the research progress of the angle from five aspects: definition, measurement, biomechanical significance, treatment and ethnic differences.

Objective: This study aimed to compare and analyze the functional differences between peripheral blood mono-cyte-derived dendritic cells (DCs) of Helicobacter pylori-positive and H. pylori-negative patients with gastric cancer. Methods:H. py-lori infection was detected in 84 patients with gastric cancer in our hospital from January 2011 to October 2012 by the 14C-urea breath test. DCs were generated from monocytes isolated by an adherent method from the two groups of patients and cultured in the presence of rhIL-4, rhGM-CSF, and rhTNF-α. Furthermore, the expression of surface marker molecules was determined by fluorescence-activat-ed cell sorting analysis. The cytotoxicity of DCs pulsed T cells against gastric carcinoma cell was assessed by the lactate dehydroge-nase-releasing assay. The secretion of IL-12 and IFN-γin the supernatant was determined by enzyme-linked immunosorbent assay. Re-sults:No difference was observed in the morphological change of the maturation process. The mean expression of CD1a, CD80, CD83, CD86, and HLA-DR molecules in DCs of H. pylori-infected patients was higher than that in DCs of H. pylori-negative group, and the differences were statistically significant except for CD1a and HLA-DR. The cytotoxicity activities, IL-12 release, and IFN-γrelease in the H. pylori-positive group were significantly higher than those in the H. pylori-negative group (P<0.05). Conclusion:H. pylori infec-tion has no effect on the morphological change of the maturation process of monocyte-derived DCs. These data clearly demonstrate that monocyte-derived DCs of H. pylori-infected patients with gastric cancer can induce stronger maturation and activation than those of H. pylori-negative patients.

In a word, this teaching reform has achieved good results in practice.

Objective: To evaluate the elastic modulus of Beagle's periodontal ligament(PDL) by means of nanoindentation, and to help build constitutive model of PDL precisely. Methods: 24 cross sections were obtained from the tooth root of lower first molars of beagle dog. With nanoindentation, intrusion and unloading to PDL sites on different planes of long axial and in different directions on the same plane of tooth root were achieved, and the load-displacement curves were obtained, from which the elastic modulus was calculated and analyzed. Results: The elastic modulus of the beagle's periodontal ligament varied from 0. 452-1. 542 Mpa. There was no significant difference in elastic modulus of the beagle's lower first premolar PDL in relation to different planes of long axial, while significant difference was found in different directions (buccal/lingual sides and mesial/distal sides) on the same plane of tooth root(P＜ 0. 05). Conclusion: There was a difference in the elastic modulus of periodontal ligament in buccal/lingual sides and mesial/distal sides of the same tooth root.
