ObjectiveTo develop an assay to quantitatively detect anti-BP180NC16A IgG subclasses and to assess the significance of anti-BP180NC16A lgG in bullous pemphigoid (BP).MethodsThe Glutathione S-transferase(GST)-BPI80NC16A fusion protein was expressed in E.coli system and purified by affinity chromatography.An improved enzyme-linked immunoabsorbent assay (ELISA) was developed and used to detect anti-BP180NCI6A IgG subclasses in serum samples from 10 patients with BP,5 patients with pemphigoid gestationis (PG),1 patient with linear IgA bullous dermatosis (LIBD) and 2 patients with pemphigus.Results The optimal condition for the ELISA was determined by cross assay as follows:the concentration of GSTBP180NC16A fusion protein for coating,500 μg/L; the condition for coating,4 ℃ for 12 hours; the dilution ratio of sera and secondary antibody,1∶ 100 and 1 ∶ 2000 respectively; the condition for incubation,37 ℃ for 1 hour;,the condition for the enzyme-substrate reaction,37 ℃ for 20 minutes.Of the 10 patients with BP,all were positive for anti-BP180NC16A IgG1,9 for IgG2,5 for IgG3,and 9 for IgG4.Anti-BP180NC16A IgG was undetected in any of the serum samples from 2 patients with pemphigus vulgaris or 1 patient with adult LIBD.All the 5 sera from patients with PG; were positive for all the anti-BP180NC16A IgG subclasses,which were predominated by IgGl and IgG3.ConclusionThe developed ELISA is a highly specific and reproducible semiquantitative method for the detection of anti-BP180NCI6A IgG subclasses in patients with BP and PG.

?receptors are particularly abundant in the CNS. ? receptors have been shown to exhibit such a wide variety of actions as modulating glutaminergic, dopaminergic and cholinergic neurotransmission. They also play an important role in maintaining cell growth and proliferation, learning and memory. Recent evidence suggests the possible involvement of ? receptors in the pathogenesis of schizophrenia. More researches are expected to supply new targets for treatment and diagnosis.

Objective:This study aims to explore the relationship between serum response factor (SRF) expression level and gas-tric cancer progression by detecting SRF expression level in cancer cells. Methods:The SRF gene in SGC-7901 cells was silenced by RNA interference. Transfection efficiency was detected by fluorescence microscopy, cell proliferation by CCK 8 method, SRF gene and protein expression level by real-time polymerase chain reaction and Western blot, and cell cycle by flow cytometry. Results:Cell treat-ment with siRNA-SRF induced significant reduction in SRF mRNA levels. Western blot analysis showed that SRF protein decreased by 40.1%in the siRNA group compared with that in the control group (P<0.05). Compared with the blank, negative, and mock transfection control groups, cell proliferation of the siRNA-SRF group decreased. The inhibition ratio reached 64.24%, as measured by the CCK-8 assay (P<0.05). Treatment with siRNA could block SGC-7901 cell cycle at G0/G1 phase (P<0.05). Conclusion:SRF expression is close-ly associated with gastric carcinoma cell proliferation. SRF protein level detection can provide a certain reference value in evaluating malignant gastric carcinoma progression. SRF is possibly an important target for the prevention and control of gastric cancers.

Objective To explore the effective of minimally invasive techniques for diagnosis and treatment of the spinal fungal infec-tions. Methods The clinical data of 6 patients with spinal fungal infection in our hospital from January 2012 to June 2014 was reviewd. All patients were taken biopsy diagnosis for spinal fungal infection by percutaneous endoscopic lumbar discectomy. Along with the oral antifungal drugs treatment,all the patients received the interbody fusion surgery by percutaneous pedicle screw fixation and debridement. The clinical and image data were collected during the 6 months following period. Results The symptoms of all the patients was relieved after surgery and no complications occurred. All the patients were followed up for 6 months. The value of ESR and CRP decreased to normal level at the first month after operation. The VAS scores decreased from (7. 0 ± 0. 8) to (0. 8 ± 0. 7) and the ODI scores decreased from (56. 1 ± 7. 7) to (5. 7 ± 2. 1). The X-ray image confirmed solid fusion at the 6 months after surgery. Conclusion The minimally invasive technique of spine is a good way to treat spinal fungal infection.

Objective To study the correlation between histopathological findings and X-ray appearances of ameloblastomas.Methods X-ray characteristics and histopathological features in 153 cases of ameloblastomas were analyzed retrospectively, and their relation was comparatively analyzed. Results ① On radiography,the lesions appeared as multilocular in 82 cases(53.59) and unilocular in 71 cases(46.41). ② 96 cases were classic ameloblastomas,including follicular type in 13 cases and non-follicular type in 83 cases,X-ray showed unilocular appearance in 35(36.46) and multilocular appearance in 61 cases(63.54).57 cases were unicystic ameloblastoma ,X-ray showed unilocular appearance in 36 cases(63.16) and multilocular appearance in 21 cases(36.84).There was significant diffrence statistically in the X-ray features of uniloculus and multiloculus between the two histopathological patterns(P﹤0.005). Conclusion Unicystic ameloblastomas often have unilocular radiologic appearance,classic ameloblastomas are mostly of multilocular radiologic appearance,while,the honeycomb radiologic appearances are common seen follicular type ameloblastoma.

Objective To survey the relationship between myocardial damage of chronic and latent Keshan disease with A360P missense mutation in desmin gene exon6. Methods By clinical epidemiology method,30 cases had been collected randomly among chronic Keshan disease patients and 30 cases equally among healthy adults (inner control groups) in Diantou town,Huangling county,Shaanxi province,a Keshan disease area,and 30 cases among health adults(outer control group) in Chang'an district,Xian city,a normal area. Genome DNA had been extracted from 90 blood samples. Different restriction sites had been analyzed by the methods of PCR,digested by restriction endonuclease and electrophoresis. By virtue of Bsp1286 Ⅰ enzyme,122 bp and 60 bp strap could be found in control group from exnn4,showing that Bsp1286 Ⅰ enzyme was active. By virtue of Bsp1286 Ⅰ enzyme,desmin gene exon6 was digested to 184 bp and 66 bp strip when A360P missense mutation site exited in exon6. Results One hundred and twenty two bp and 60 bp strap could be found in control group from exon4 digested by Bsp1286 Ⅰ ,which showed Bsp1286 Ⅰ enzyme was active. Two hundred and fifty bp strips can only be found in digest products of exon6. One hundred and eighty-four and 66 bp strips which were the products of DNA digested by Bsp1286 Ⅰ could not be found. A360P missense mutation site of desmin gene exon6 had not been found among chronic and latent Keshan disease patients and tow control groups in Keshan disease area and in normal area. Conclusions A360P missense mutation site of desmin gene exon6 has not been found among chronic and latent Keshan disease patients. A360P missense mutation of desmin gene exon6 probably is not predisposing genes of chronic Keshan disease.
