Objective This study aims to test the hypothesis that low density granulocytes (LDGs) is involved in the pathogenesis of DM associated-Interstitial lung disease (ILD).Methods Forty eight DM patients (28 with ILD) and 19 age-and sex-matched healthy Chinese volunteers were recruited to this study.LDGs percentage in peripheral blood mononuclear cells (PBMCs) was tested by flow cytometry.Neutrophilrelated genes (LL-37,MPO and MMP-8) expressions in PBMCs were tested by quantitative RT-PCR.Myositis disease activity assessment visual analogue scales (MYOACT) was used to assess the disease activity.Percentages of LDGs were compared in patients with ILD and without by using unpaired t test with Welch's correction,the correlations between LDGs and clinical parameters were further analyzed by linear correlation analysis.The expressions of neutrophil-related mRNA and proteins in PBMCs were compared by using MannWhitney U test.Results LDGs percentage in PBMCs was 7.1-fold higher in DM patients than healthy controls [(9.1±11.5)％ vs (1.3±0.7)％,t=4.664,P＜0.01].LDGs percentage in PBMCs was 2.7-fold higher in DM patients with ILD than DM patients without ILD [(12.3±14.1)％ vs (4.5±2.6)％,t=2.835,P=0.008 3].The mRNA expression level of LL-37,MPO and MMP-8 and LL-37 protein levels in the DM group were significantly higher than those in the control group.LDGs percentage positively correlated with MYOACT lung disease activity scores (r=0.439,P=0.010).Conclusion Percentage of LDGs in PBMCs is significantly increased in DM patients with ILD and positively correlated with MYOACT lung disease activity scores,suggesting that abnormall increasing of LDGs is a potential contributor to the pathogenesis of DM-associated ILD.

Objective To study the clinical features and treatment of cervical spondylosis with dissociated motor loss in upper extremity. Methods Data analysis was done in 10 patients with cervical spondylosis with dissociated motor loss in upper extremity, in aspects of symptoms, sign, radiologic feature, electromyogram and treatment. Results There are 2 subtypes of cervical spondylosis with dissociated motor loss in upper extremity: Keegan and Non-Keegan types. The patients with Keegan type of cervical spondylosis manifested weakness and atrophy in the upper extremity, and no radicular pain was reported. The Non-Keegan type is in fact a combination of radicular and spinal insult in the cervical region. Our clinical practice showed that surgical operation was preferred to the conservative treatment for patients with this disease. Conclusion A well understanding of this disease is of great importance for avoiding mistakes in diagnosis and treatment of this disease.

Objective To investigate the related risk factors in patients with atrial fibrillation in order to prevent and delay the occurrence of atrial fibrillation.Methods Five hundred and fifty-eight inpatients with atrial fibrillation were retrospectively analyzed from June 2005 to June 2008.They were divided into several groups according to the age and the characteristics of the elder patients with atrial fibrillation were analyzed.Results In the 558 cases with atrial fibrillation, there were 298 males (53.4%) and 260 females (46.6%) aged from 21 to 97 years.The average age was (72.8 ±10.1) years.There were 57 cases aged 21-59 years(10.2 %)and 501 cases aged 60-97 years(89.8 %).The total number of inpatients in our hospital was 11 869, and there were 4049 cases aged<60 years, 2527 cases aged 60-69 years, 3971 cases aged 70-79 years, 1244 cases aged 80-89 years and 78 cases aged>90 years.The proportions of the inpatients with atrial fibrillation in the above five age groups of inpatients were 1.4%(57 cases), 4.2%(107 cases), 6.6% (262 cases), 9.5%(118 cases)and 17.9% (14 cases), respectively.In 558 cases with atrial fibrillation, there were 230 cases (41.2%) with paroxysmal atrial fibrillation, 44 cases (7.9%) with persistent atrial fibrillation and 284 cases (50.9%) with permanent atrial fibrillation.The most common underlying disease was hypertension in the 558 cases, followed by coronary heart disease, heart failure, diabetes, rheumatic heart disease and so on.Conclusions The prevalence of atrial fibrillation is increased with aging.Hypertension, coronary heart disease, rheumatic heart disease, heart failure, hyperthyroidism,diabetes, chronic pulmonary disease and renal failure are all the risk factors for atrial fibrillation.

Objective To discuss the relationship of hypertension with ageing and comorbidities in 6426 inpatients. Methods The data of 6426 inpatients with hypertension from May 2005 to May 2009 were analyzed retrospectively. All inpatients were divided into four groups: the young-aged group from 18 to 44 yrs (n= 312, 4. 8%), the middle-aged group from 45 to 59 yrs (n= 1529,23.8%), the elderly group from 60 to 79 yrs (n=3847, 59.9%) and the old old group from 80 to 99 yrs (n=738, 11.5%). The percentages of hypertension patients in the same age group over the same period were calculated and the comorbidities were observed respectively. Results Of 6426 hypertensive cases, there were 3438 males (53.5%) and 2988 females (46.5%), ranging from 18 to 99 yrs with the average age of (66.3± 12. 1) yrs. There were 25 504 inpatients over 18 years old including 11 208 in the youth group, 5389 in the middle-aged group, 7596 in the elderly group and 1311 in the old old group. The proportions of hypertension inpatients to total in-patients in the four age groups were 2.8%, 28. 4%, 50.7% and 56.3% respectively. In the youth and middle-aged groups, numbers of males with hypertension were more than of females, however there was no significant difference in gender in the elderly and the old old groups. Within 6426 inpatients with hypertension, 2069 (32.2 %) had diabetes mellitus, 1508 (23.5%) had hyperlipidemia, 105 (1.6 % )had sleep apnea syndrome, 1061 (16.5%) had coronary artery disease, 904 (14.1%) had heart failure, 2353 (36.6%) had stroke and 678 (10. 6%) had kidney failure. Conclusions The prevalence of hypertension increases with ageing significantly. The correlated risk factors for hypertension include diabetes mellitus, hyperlipidemia and sleep apnea syndrome, being a clustering phenomenon, especially for elder patients. These risk factors also deteriorate the damage on heart,brain, kidney and other target organs, which might ultimately result in serious cardio-cerebral vascular events. Therefore, besides control of blood pressure, we should strengthen the complex treatment on hypertension to prevent and delay the occur of complicating diseases.

Objective To assess the theoretical knowledge and practical skills of parasitic diseases among technicians from disease control and prevention institutions. Methods The Assessment on National Parasitic Disease Control and Prevention Techniques was organized in September,2015. Together,124 subjects from disease control and prevention institutions at prov-ince,prefecture or county levels in 31 provinces joined the assessment. A database was built consisting of subjects'basic infor-mation and assessment scores. Statistical analysis was used to analyze the scores by gender,age,professional title,institutions and places of participants. Results The average total score of all the subjects was 123.3,with a passing rate of 57.3%. The av-erage scores of male subjects(48 subjects)and female subjects(76 subjects)were 125.9 and 121.7 respectively;the average scores of the subjects aged under 30 years(57 subjects),between 30 and 40 years(61 subjects)and above 40 years(6 sub-jects)were 119.6,128.1 and 111.2 respectively;the average scores of persons with junior(94 subjects),intermediate(28 sub-jects)and senior(2 subjects)professional titles were 119.2,135.9 and 140.5 respectively. The average theoretical assessment score of all the subjects was 61.9,with a passing rate of 62.9%. The average practical skill assessment score of all the subjects was 61.4,with a passing rate of 58.1%. Conclusions The theoretical assessment results range widely. The theoretical knowl-edge results of technicians from disease control and prevention institutions are low in general. Therefore ,the specific training based on daily work needs to be enhanced.

Objective To evaluate the influence of grape seed proanthocyanidin extract (GSPE) on sunburn cell formation and p53 protein expression induced by acute ultraviolet injury. Methods Ten volunteers were enrolled in this study. The buttock region served as the exposed region. Four areas were randomized and delineated on the buttock: one area (control area) received no exposure or product, the other 3 areas were exposed to two minimal erythema doses (MED) of simulated solar radiation (SSR) for 3 days. Of the 3 exposed areas, one area (SSR) received no product before exposure, one area (SSR + Veh) was pretreated with vehicle, the third area (SSR + GSPE) with the samples of GSPE. GSPE or vehicle was applied 30 minutes before each exposure at 2 μL/cm2. Skin biopsy was performed 24 hours after the last exposure, and skin specimens were subjected to hematoxylin eosin (HE) staining and histochemical analysis for p53 protein. Results There was a statistical difference in the number of sunburn cells per high power field (×200) between SSR sites and SSR + GSPE sites (29.8±11.1 cells vs 2.2±0.2 cells, P<0.01). A significant decrease was noticed in the account of p53 protein-positive cells per high power field (×200) in SSR + GSPE sites com-pared with the SSR sites (4.6±0.7 cells vs 19.3±3.4 cells, P<0.05). Conclusion GSPE exerts a poten-tial protective effect against acute ultraviolet injury and can serve as a natural sunscreen.

Clinical data and manifestations on muhi-slice spiral CT (MSCT) of 11 patients with disseminated peritoneal adenomucinosis (DPAM) were retrospectively reviewed.The CT manifestations were also compared with surgical and histopathological findings.MSCT findings showed a large amount of gel-like ascites in 9 cases and local cystic masses in 2 cases.Among 9 cases with a large amount ascites,abdominal multiple cystic masses were shown in 5 case,and infiltration of the greater omentum and mesentery in 5 cases.Hepatic scalloping was found in 6 cases ; parenchymal invasion of the liver or spleen were showed in 5 cases; calcification of the cystic masses in 5 cases.Ovary mueinous cystadenoma was presented in 3 female patients.Enlarged lymph nodes and omental cake were not found in all cases.The results indicate that the characteristic MSCT manifestations of DPAM include diffuse gel-like ascites,multiple cystic masses with or without calcification,hepatic scalloping and parenchyma invasion.
