A retrospective analysis was carried out in 36 patients with blunt diaphragmatic rupture during March 1991 and March 2006. Twenty-two diagnoses were confirmed preoperatively, and the rest 14were confirmed perioperatively. Three patients underwent surgical treatment after no response to conservative therapy. Thoracotomy was performed in 21 patients, laparotomy in 9, thoracotomy plus laparotomy in 5 and combined thoraco-laparotomy in 1. Most diaphragmatic rupture may be caused by blunt collision and could lead to thoracoabdominal injury. In spite of high mortality rate, the condition is usually under diagnosed. Definite diagnosis and timely operation are important to increase survival rate and reduce mortality.

Objective To investigate the serum level of calcium-binding protein A9(S100A9)in patients with rheumatoid arthritis and explore its potential clinical significance. Methods The serum level of S100A9 was measured by ELISA in 79 rheumatoid arthritis (RA) patients and 20 healthy controls (HC). The correlation of S100A9 level and relevant clinical parameters were analyzed. Results The serum level of S100A9 was significantly increase in RA patients than those in HC. The serum level of S100A9 was higher in high disease activity than that in moderate and low disease activity in the RA group. There was a positive correlation in serum S100A9 level and DAS28 score,Rheumatoid factor,tender joint count and swollen joint count. Conclusion The serum level of S100A9 increases in RA patients and correlates with RA activity.

Objective:To provide a retrospective analysis of the levels of occupational external exposure of radiation workers in Hubei province from 2009 to 2018 in a way to prevent and control its risks.Methods:The external individual doses were surveyed for 50 070 radiation workers between 2009 and 2018 by the effort of the Hubei Provincial Center for Disease Control and Prevention. Under the relevant national standards, the external radiation doses to radiation workers were conducted by using TLDs.Results:The average annual collective effective dose to radiation workers in a 10 years period was 1.93 man·Sv, the median of average annual effective dose of 0.14 mSv ( P25- P75: 0.06-0.30 mSv), and the average annual effective dose of 0.40 mSv. The annual effective doses received by 46 562 workers were less than 1 mSv, accounting for 92.99% of the total monitored workers. The annual effective dose varied dependent on occupational categories, showing a year-by-year decline trend and staying at a low level after 2012. The relative high radiation doses were seen in nuclear medicine and interventional radiology in medical applications, non-destructive testing and well logging in industrial applications, and other types of radiation applications. Conclusions:The average annual effective dose decreased year in a by year manner and kept at a low level. This indicated that the radiological protection measures taken during the 10 years ensure the health of workers. The continuous monitoring result suggest that much more attention should be paid to such categories workers as nuclear medicine, interventional radiology, non-destructive testing, well logging and others through improving radiation protection measures.

Objective To understand the impairment and compensation mechanism of brain function in pa-tients with non-fluent aphasia after ischemic stroke. The fractional amplitude of low frequency fluctuation (fALFF) method was used to analyze the functional magnetic resonance imaging (fMRI) data in the resting state between the aphasia patients and the normal controls. Methods The scans of the resting state of fMRI were performed in 17 aphasia patients and 19 age-, education-, and sex-matched healthy control subjects. The scan sequence was single-shot echo planar image,DPARSF software was used to analyze fALFF data of the aphasia patients and the healthy controls. Results Compared to the control group, the value in right superior temporal gurus, inferior parietal lob-ule, frontal lobe cortex, and postcentral gurus were significantly increased in the aphasia group. The fALFF in bilat-eral cerebellum and right thalamus were also decreased in the aphasia group. Conclusions The fALFF values in some brain region in the aphasia group were abnormal in the resting state , indicating a few pathological change of brain function in patients with non-fluent aphasia after ischemic stroke.

[Objective]To investigate the value of degree centrality(DC),a novel resting-state fMRI parameter,in voxel-wise whole-brain functional networks analysis in primary insomnia(PI)after acupuncture therapy.[Methods]The resting state fMRI were performed in 29 PI patients and 22 age,education,and sex-matched normal healthy subjects. Analysis of DC map changes between the two patient groups and the control group were performed by two sample t test.(threshold at P<0.05).[Results]Compared with the control group,patients with PI showed significantly reduced DC value in middle temporal gyrus(MTG. R);hippocampus(HIP. B);parahippocampal gyrus(PHG. R);putamen(PUT. R);cuneus(CUN. L).[Conclusions]Changes of DC value occurred in some region of brain in the PI patient groups when compared with the control group. It was indicated that DC ,as a novel resting-state fMRI parameter in the voxel-wise whole-brain functional networks ,might be an appealing alternative approach for further study on pathologic and neuropsychological states of PI.

Objective To investigate the prevalence and risk factors of hyperuricemia (HUA) in rural residents of Gaoyou City,Jiangsu Province.Methods A total of 4504 rural residents were investigated in a cross-sectional study.Questionarre survey and physical examination were used for the stndy.Fatsing venous blood samples were collected for biochemical examination.T-test,chi-square test for multiple-group data comparison and logistic regression analysis were used for statistical analysis.Results The prevalence of HUA was 11.9％,15.7％ in male,which was significantly higher than 8.6％ in the female (P＜0.01),the risks of HUA in male was 1.98 times higher than in female.The average value of serum uric acid in this population was higher than.that of female.The prevalence of HUA in female increased with age.Non-conditional logistic regression analysis showed WHR,Cr,Tg,hypertension were the independent risk factors of male patients with HUA.Age,BMI,Cr,Tg,hypertension were independent risk factors of HUA in female.Conclusion The prevalence of HUA can be affected by age and sex.Weight control,keeping blood pressure and blood lipid profiles in normals levels are important for the prevention of HUA.

Objective To study the expression of Adiponectin (AD) and its receptors Adiponectin receptor 1 (Adipo R1) and Adipo R2 in the synovial fluids and the synovium of rheumatoid arthritis (RA). Methods ELISA was used to determine the levels of AD in 23 RA and 23 osteoarthritis (OA) patients. Real-time PCR and Western blot techniques were employed to study the expression of AD, AdipoR1 and AdipoR2 in the synovium of 10 RA and OA patients. Results It was observed that approximately twice more adiponeetin in the synovial fluids of patients with RA than with OA. Adiponectin and AdipoR1, but not AdipoR2 mRNA, were significantly expressed in synovium of RA patients in comparison with OA. Adiponectin and AdipoR1 protein were wuch more expressed in synovium from RA than those from OA. Conclusion High expression of Adiponectin and AdipoRl is likely to contribute to the formation of inflammatory joints in RA.

Objective To explore the potential role of high levels of adiponectin (AD) in the inflammatory joint of rheumatoid arthritis (RA). Methods ELISA was used to measure the levels of AD, IL-Iβ,IL-6, IL-8, TNF-α, MCP-1 and MMP-9 in the synovial fluids of RA and osteroarthritis (OA), the levels of these cytokines were tested after the synovial fibroblasts (SFLs) were stimulated with AD. Doublelabeling immunohistochemistry was used to analyze the expression of AD in RA synovium. Cytokines were measured by ELISA after SFLs were stimulated with AD. The expression of RANKL was detected by real-time PCR after MH7A were treated with AD and IL-6 ANOVA, Student's t-test, Mann-Whitney U-tese, Spearman's-test were used for statistical analysis. Results High levels of AD in RA synovial fluids were correlated with IL-6 levels. Double labeling immunohistochemistry showed that AD was localized in fibroblasts. MCP-1 and IL-6 were dramatically increased in human synovial fibroblasts following incubation with recombinant AD for 24 h. RANKL mRNA was significantly increased in MH7A after treated with AD and IL-6. Conclusion High levels of AD in the inflammatory joints of RA are likely to contribute to the high expression of IL-6, MCP-1 and RANKL, which may play an important role in the chronic inflammation, osteoclasts activation and bone erosion in RA.
