0.05). Removal of two thirds or the entire horizontal portion of the TFCC caused a statistically significant difference in the percentage of force transmitted through the ulna compared with the intact force data (t=3.4,P

Objective To determine the monokine levels of serum and synovial fluid (SF) in patients with JSpAs and estimate the correlation between monokines and inflammatory indices.Methods Serum and SF monokines (IL 1?,IL 1?,IL 6,IL 8,IL 12 and TNF ?) were measured by sandwich ELISA in patients with JSpAs ( n =28) and healthy controls ( n =10).The correlation between serum monokines and inflammatory indeces and between both serum and SF monokine levels was analysed.Results Elevated serum level of IL 6 was found in patients with JSpAs as compared to healthy controls ( P

Objective To investigate the dynamic variation of subsets of myeloid derived suppressor cells (MDSC) and their ratio in septic mice, and to discuss their role in the development of sepsis. Methods Male C57BL/6 mice were randomly divided into sepsis model group and sham group according to random number table. Polymicrobial sepsis was induced by using cecal ligation and puncture (CLP), while mice in sham group only underwent laparotomy and laparorrhaphy without CLP. Thirty mice in each group were used to observe living condition, and the 20-day survival rate was compared between the two groups. In addition, subsets of MDSC in peripheral blood, spleen and bone marrow were analyzed with flow cytometry for other 60 mice (12 mice at each time point, as 0, 3, 7, 12 and 20 days). Spleens were harvested at 7 days for weighing, and single cell suspension of spleen tissue was prepared for splenocyte counting. Histopathologic changes in spleen tissue and liver tissue were observed under light microscope after hematoxylin and eosin (HE) stain. Results ① No mice died in sham group within 20 days after the operation. On the other hand, 10 mice in model group died within 20 days, and the difference in survival rate between the two groups was statistically significant (100.0% vs. 66.7%, χ2 = 11.861, P = 0.001). ② The spleens in model group showed obvious enlargement and significantly outweighed as compared with those in sham group (mg: 413.33±41.63 vs. 111.67±17.56, t = 11.564, P = 0.000), and the total count of splenocytes was significantly higher than that in sham group (×109/L: 21.20±2.43 vs. 1.87±0.06, t = 13.578, P = 0.005). ③ Pathological sections with HE staining showed that the liver tissue and spleen tissue remained normal in sham group. In model group, the hepatic tissue showed acute inflammatory reaction, including tissue disruption, capillary congestion, infiltration of neutrophils, marked edema of hepatocytes and focal hepatocellular necrosis. Abnormalities were also found in the spleen tissue: the red pulp and white pulp were disordered, splenic sinus was congested with numerous red cells, the splenic capsule thickened, immature myeloid cells with circular nuclei proliferated in the subcapsular region and perivascular region, splenic cord and splenic sinus were infiltrated with a large number of hematopoietic cells. ④ No significant changes in the monocytic MDSC (M-MDSC) and granulocytic MDSC (G-MDSC), and their ratio were found in peripheral blood, spleen and bone marrow at every time point in sham group. On the other hand, in model group, the ratio of M-MDSC and G-MDSC was continuously increased in peripheral blood, spleen and bone marrow, and M-MDSC only slightly decreased at 20 days. On the other hand, the ratio of M-MDSC/G-MDSC rose at first followed by a decrease. The ratio of M-MDSC/G-MDSC in peripheral blood was higher than 1 from 3 days after the operation, reaching the peak at 12 days (compared with 0 day: 4.16±0.53 vs. 0.79±0.11, P < 0.05), while the ratio of M-MDSC/G-MDSC in spleen and bone marrow after CLP were lower than 1 at all time points, reaching the peak on 7 days after the operation (compared with 0 day: 0.70±0.06 vs. 0.25±0.02 in spleen, 0.39±0.06 vs. 0.11±0.01 in bone marrow, both P < 0.05), and then gradually decreased afterwards. Conclusion Subgroups of MDSCs were continuously aggregated in the peripheral blood, spleen and bone marrow, and their ratio rose first and decreased afterwards along with the development of sepsis, and the changes may reflect the change of immune status at different stages of sepsis.

Objective To study the clinical features of follicular occlusion triad, and whether it is a hereditary disease. Methods Based on the clinical examination of a case who developed squamous cell carcinoma secondary to follicular occlusion triad, the pedigree of the patient was surveyed and analyzed. Results There were a total of thirteen patients in this pedigree, the age of onset was about 20 years old. The clinical features and laboratory examination of the proband was consistent with follicular occlusion triad. Conclusions Hereditary factor is important in the pathogenesis in follicular occlusion triad,and the disease maybe an autosomal dominant inherited disease.

Department of rheumatology and immunology is a compulsory training department for the standardization training of the residents. However, it has been noted that the residents often ignore the importance of rheumatology. They are usually short of communication skill with the patients and theoretical knowledge. They often have high error rate in the clinical work and training their clini-cal skills and thinking ability is very difficult in the actual work. All of these problems may decrease the training quality and make the training a mere formality. Therefore, in order to carefully implement resident standardization training, a set of specific training programs has been developed, involving in theory of knowledge, practice standardization and comprehensive quality training. With these training programs, the quality and efficiency of the residents' training has greatly improved.

Objective To study the gait footprint parameters of the normal children and the cerebral palsy (CP) children, and to explore its clinical value. Methods A total of 2 800 normal children aged 3 to 10 years and 139 spastic CP children aged 3 to 5 years were recruited in this study. The normal children were divided into seven groups with one year interval, and were measured with regard to the length of foot and step, step width and foot angle of footprint of every age group with self made oil printed carpet. The footprint of the CP children were measured and compared with that of the normal children at the same age. Results It was revealed that there was significant difference between the normal and the CP children ( P

Objective To investigate the risk factors of in-stent restenosis (ISR) after coronary implantation of drug-eluting stent Methods One hundred and fifty-seven patients including 118 males and 39 females,who underwent successful implantation of drug-eluting stent, were recruited in the study. The patients were divided into the restenosis group (33 patients) and non-restenosis group ( 124 patients) according to the angiographic results. The associations of ISR with clinical and coronary angiographic characteristics were analyzed using univiriate analysis and logistic regression. Results In the restenosis group,there were 18 cases of diabetes mellitus ( 54. 5% ), 26 cases of frequency angina ( 78. 8% ), which were significantly higher than those of 31 cases of diabetes (25.0%) and 72 case of frequent angina (58. 1% ) in the non-restenosis group (χ2 = 10. 60, P ＜ 0. 01, χ2 = 4. 77, P = 0. 03 for diabetes mellitus and frequent angina, respectively). Compared to non-restenosis group, the occurrence rates of chronic total occasion, bifurcatus lesions, diffuse lesions were significandy higher in the restenosis group ( 19. 3% vs 7. 6% χ2 =5.92,21.1% vs 10. 2% χ2 =4. 34,26. 3%vs 12. 1% χ2 =6. 32,Ps ＜0. 05). Fifty-seven stents were implanted into the restenosis group,and one hundred and fifty-seven into the non-restenosis group. Logistic regression analysis showed that diabetes, frequent angina,chronic total occlusion lesions, bifurcatus lesions, diffuse lesions, stent length and diameter were significantly associated with restenosis ( OR value were 3.52,2. 59,3.05,3. 14,3.08,0. 93,95% CI were 1.56 - 7.90,1.02 - 6. 59,1.11 - 8. 36,1.30 - 7.59,1.34 - 7.05,0. 88 - 0. 98 respectively, Ps ＜ 0. 05 ). Conclusion After implantation of drug-eluting stent, diabetes mellitus, chronic total occasion lesions, frequent angina, diffuse lesions, bifurcatus lesions and stent length and diameter are associated with follow-up restenosis.

Objective To seek more direct evidence of the role of the posterior parietal cortex (PPC) in controlling visuospatial attention.Methods Forty healthy subjects took the Attention Network Test following continuous theta burst stimulation (cTBS) applied over the left or right PPC or sham stimulation.The Attention Network Test measures the alerting,orienting and executive control components of visual attention separately.Results Subjects responded to spatial cues significantly slower after cTBS.Alerting and orienting showed deficits after cTBS over the right PPC.cTBS over the left PPC resulted in significant improvements in alerting,but not in the orienting.Furthermore,there were significant differences in the alerting and orienting indices between cTBS over the left and right PPC,but not in the executive control index.Conclusions The results suggest that the right PPC is associated with spatial orienting and the alerting function.The findings supported the theory of inter-hemispheric competition for visuospatial attention.Visuospatial attention bias might be selectively modulated through cTBS.
