Objective:To observe the effects of bundled pulmonary rehabilitation on static pulmonary function, cardiopulmonary exercise function and inflammatory factors in patients with moderate or severe stable chronic obstructive pulmonary disease (COPD).Methods:Sixty moderate or severe COPD patients in stable phase from December 2017 to October 2018 in Affiliated Zhongshan Hospital of Dalian University were selected. The patients were divided into control group and rehabilitation group by random digits table with 30 cases each. The patients of control group received routine medicine therapy, and the patients of rehabilitation group received bundled pulmonary rehabilitation besides routine medicine therapy. Pulmonary function, cardiopulmonary exercise function and inflammatory factors in each group were tested before treatment and 3, 6 month after treatment.Results:In control group, there were no statistical differences in the pulmonary function, including the forced expired volume in one second (FEV 1), FEV 1 as percentage of predicted (FEV 1%pred), FEV 1/forced vital capacity (FVC); cardiopulmonary exercise function, including the peak load, peak VO 2, peak VO 2 as percentage of predicted (peak VO 2% pred), peak VO 2/kg, peak VE 3 and 6 months after treatment compared with those before treatment ( P>0.05); in rehabilitation group, there were no statistical differences in the indexes 3 months after treatment compared with those before treatment ( P>0.05), the indexes 6 months after treatment were significantly improved compared with those before treatment and 3 months after treatment ( P < 0.05). In control group, the C-reactive protein (CRP) and interleukin (IL-6) before treatment and 3 months after treatment and tumor necrosis factor-α (TNF-α) before treatment and 3, 6 months after treatment had no significant difference ( P > 0.05); the CRP and IL-6 6 months after treatment were significantly lower than those before treatment and 3 months: (5.48 ± 0.91) mg/L vs. (6.26 ± 0.99) and (6.09 ± 0.97) mg/L, (9.17 ± 1.04) ng/L vs. (10.83 ± 1.79) and (10.29 ± 1.53) ng/L, P < 0.05. In rehabilitation group, the CRP, IL-6 and TNF-α 3 and 6 months after treatment were significantly lower than previous phase: (5.21 ± 0.87) and (5.67 ± 0.91) mg/L vs. (6.15 ± 0.92) mg/L, (8.56 ± 1.17) and (10.03 ± 1.61) ng/L vs. (11.06 ± 2.01) ng/L, (7.16 ± 1.33) and (8.05 ± 1.62) ng/L vs. (8.97 ± 2.05) ng/L, P < 0.05. In rehabilitation group, the CRP, IL-6 and TNF-α before and after treatment were negatively correlated with pulmonary function (FEV 1, FEV 1% pred and FEV 1/FVC) and cardiopulmonary exercise function (peak load, peak VO 2, peak VO 2% pred, peak VO 2/kg and peak VE) ( r=- 0.641 to - 0.884, P < 0.01). Conclusions:Bundled pulmonary rehabilitation in patients with moderate or severe stable COPD can improve pulmonary function and cardiopulmonary exercise function and reduce inflammatory factors.

Objective: To analyze the clinical characteristics of patients with relapsed/refractory primary central nervous system lym-phoma (PCNSL) and to explore the factors that influence the prognosis, in order to provide evidence for the clinical diagnosis and treat-ment. Methods: Sixty-four patients with relapsed/refractory PCNSL diagnosed from October 2006 to August 2015 were selected. The clinical features, treatment plans, and laboratory examination data were retrospectively analyzed. Cox regression was used for multi-variate analysis. Results: Univariate and multivariate analyses showed that progression-free survival of first time (PFS1)≤1 year and Kar-nofsky performance status (KPS) score<70 points were independent prognostic factors in patients with first relapsed/refractory PCNSL. The median PFS2 and overall survival of second time (OS2) were 19 and 21 months, respectively, in patients with PFS1≥1 year, where-as the median progression free survival of second time (mPFS2) and OS2 were 10 and 14 months, respectively, in patients with PFS1<1 year. The median PFS2 (mPFS2) in patients with first relapse/refractory KPS score≥70 points and those with KPS score<70 points were 40 and 10 months, respectively, and the median OS2 were 43 and 12 months, respectively. The median PFS for the methotrexate (MTX) and non-MTX groups was 18 and 10 months, respectively. Multivariate analysis showed that the salvage therapy was a relevant factor influencing the patient's PFS. However, univariate analysis showed that the median OS2 in the MTX and non-MTX groups was 23 and 12 months, respectively, with significant difference but without any correlation with prognosis. Conclusions: progression-free sur-vival (PFS)≤1 year and KPS score<70 were independent prognostic factors in patients with first relapsed/refractory PCNSL. Patients with relapsed/refractory PCNSL who continuously received high-dose MTX-based treatment may have improved long-term treatment outcomes.

Objective:To study the CT features for solitary fibrous tumor (SFT) in the abdomen and pelvis and to improve the diagnostic accuracy.Methods:Fourteen patients with SFT were collected in our hospital from January,2011 to December,2015.Characteristic of images were analyzed and compared for 10 SFT,which located outside the abdominal organs with extragastrointestinal stromal tumors (EGIST),leiomyosarcoma,and schwannoma.Results:Necrosis and cystic formation were frequently present in SFT in the abdomen and pelvis.CE-CT showed serpentine vessels along the periphery,while pattern of enhancement was maplike inhomogeneous progressive.Comparing with the EGIST or schwannoma,the difference of CT value in non-contrast and the arterial phase were statistically significant (P＜0.05).The numbers of peritumoral circuity vessel were significantly different between SFT and EGIST (~=18.27,P＜0.008) or between SFT and schwannoma (x2=19.25,P＜0.008).Comparing with the leiomyosarcoma or schwannoma,SFT located outside the abdominal organs.We found that tumor necrosis rate was significantly different between SFT and leiomyoscarcoma (x2=8.00,P＜0.008).Conclusion:SFT in the abdomen and pelvis show certain CT characteristics.The CT value in noncontrast and at the arterial phase,tumor necrosis rate,and serpentine vessels along the periphery were pivotal in differentiating SFT from leiomyosarcoma,EGIST and schwannoma.

Objective To study the effect of lipid peroxidation and anti-lipid peroxidation and the pigment in skin of C57BL/6 mice exposed to arsenic.Methods Forty male C57BL/6 mice were divided into four groups via the random number table method,ten mice in each group,and the mice were fed ad libitum drinking water containing arsenic at 0,1,5 and 25 mg/L concentrations for a period of 6 weeks,respectively.Twelve days before the end of the experiment,procedure of depilation was performed to induce anagen of hair cycle.On the 30th day of experiment,the activity of superoxide dismutase (SOD) was determined by nitrite method,the activity of glutathione peroxidase (GSH-Px) was determined by dithiobisobenzoic acid method,the content of malondialdehyde (MDA) in skin of C57BL/6 mice was determined by thiobarbituric acid method.Melanin was measured by NaOH dissolution method.Results No significant difference was found in body weight and water intaken between groups (F =0.119,0.363,P ＞ 0.05).The activity of SOD [(16.00 ± 5.05),(13.96 ± 2.02),(10.46 ± 3.14) U/mg prot] in 1,5 and 25 mg/L arsenic groups were all significantly lower than that in control group [(20.36 ± 4.82) U/mg prot,P ＜ 0.05].GSH-Px activity in 1,5 and 25 mg/L arsenic groups [(98.14 ± 23.92),(87.18 ± 10.87),(53.56 ± 19.97) U/mg prot] were all significantly lower than that in control group [(119.34 ± 33.14) U/mg prot,P ＜ 0.05].While MDA levels in 5 and 25 mg/L arsenic groups [(9.09 ± 2.04),(11.48 ± 2.21) nmol/mg prot] were significantly higher than that of control group [(6.19 ± 0.56) nmol/mg prot,P ＜ 0.05] and that of 1 mg/L arsenic group [(6.52 ± 1.67) nmol/mg prot,P ＜ 0.05).No significant difference was found in melanin levels (P ＞ 0.05).Conclusions Lipid peroxidation and the decreasing of antioxidation may be one of the mechanisms of arsenic-induced skin damage.Arsenic-induced skin melanin content change is not found.

BACKGROUND:It is generaly believed that the spine wil be extended, and vertebral muscle atrophy, bone loss of vertebral body, increased height and area of intervertebral disc, changes of composition of intervertebral disc wil occur in the condition of weightlessness. These are likely to be the cause of high incidence of low back pain. OBJECTIVE:To observe changes in lumbar spine bone microstructure analysis of simulated weightlessness on rhesus lumbar spine biomechanics. METHODS:Fourteen young rhesus monkeys were randomly divided into two groups: control group (n=7;free activities in the cage during the experiment), and experimental group (n=7; the use of head-down-10° on a special bed by bundle lying to simulate weightlessness). RESULTS AND CONCLUSION:(1) The results of Micro-CT examination: in the experimental group, structure model index in trabecular bone of increased. Trabecular bone changed from plate-like to the rod-like change. The intersection number of bone tissue in unit length to non-bone tissue declined. The average width of the canal between the trabecular bone increased, suggesting that there have been signs of osteoporosis in the experimental group. (2) Under an optical microscope, in the experimental group, bone hyperplasia line was disordered and irregular. Thick endplate trabecularbone became smal, shalow, and arranged substantialy perpendicular to the direction of trabecular bone and cartilage endplate. The closer the endplate surface, the smaler trabecular bone was. Compared with the control group, these smal trabecular bones were thin and curved. Bone marrow cavity was oval. The degree of the connection between the trabecular bones is poor, reflecting the structural characteristics of significant osteoporosis. (3) It is indicated that weightlessness affected the biomechanical properties of rhesus lumbar motion unit.

OBJECTIVE: To evaluate the diagnostic value of liver imaging reporting and classification criteria of data system (LI-RADS) MRI on primary hepatic carcinoma (HCC).
 METHODS: The MRI images of 100 patients (72 patients with HCC, 4 with regenerative nodules, 13 with hemangioma, 4 with liver cyst, 3 with Liver abscess, 2 with inflammatory pseudotumor, 1 with hepatic arteriovenous fistula, 1 with Limitations of steatosis) with liver disease were collected in Xiangya Hospital from January, 2014 to January, 2015. All patients were at the risk of HCC. The images were reviewed according to the LI-RADS categorization by American College of Radiology (ACR) under a condition of blindness to the pathological data. The sensitivity, specificity and the area under the ROC curve in the diagnosis of HCC with the LI-RADS categorization were calculated by three associate professors from the Department of Radiology, Xiangya Hospital.
 RESULTS: The area under the ROC curve was 0.925 in the 100 patients with HCC. Of the 100 pathologically confirmed patients, 20 cases were LR1 and LR2. However, the post-operation pathological examination showed benign tumor (negative predictive value was 100%). There were 25 HCC in 31 cases of LR3, 27 HCC in 29 cases of LR4 (positive predictive value was 93.1%). All of 20 cases of LR5 were HCC (positive predictive value was 100%). If LR1 and LR2 were considered negative, and LR3, 4, 5 were positive, then the sensitivity, the specificity and the area under the ROC curve was 100%, 71.4% and 0.925, respectively. If LR1, 2 and 3 were considered negative and LR4 and LR5 were positive, the sensitivity, the specificity and the area under the ROC curve was 100%, 90.9% and 0.974, respectively.
 CONCLUSION The MRI LI-RADS categorization is highly sensitive and specific in the diagnosis of HCC, which can improve the diagnostic accuracy.

OBJECTIVETo investigate the epidemic status of Hepatitis B in children aged 1-14 in 3 counties of Guangdong province in 2013, and to evaluate the effect of hepatitis control in children aged 1-14 after hepatitis B vaccine was integrated into the national immunization program in 2002 and catch-up vaccination was conducted from 2009 to 2011.

METHODSA multi-stage stratified random sampling was designed to survey 1 621 children aged 1-14 in rural area of Nanxiong county, Haifeng county and Xinxing county by questionnaires including general information, medical history and risk factors. The samples were tested with chemiluminescence method to detect hepatitis B virus (HBV) surface antigen (HBsAg), antibody to HbsAg (anti-HBs) and antibody to HBV core antigen (anti-HBc). Chi-square test was used to compare the positive rate of HBV serum markers in different age groups, vaccine histories, birth weight and HBV infection status of mother.

RESULTSAmong the children aged 1-14 in 3 counties rural regions of Guangdong province, the positive rate of HBsAg, anti-HBs, and anti-HBc was 1.11% (18/1 621), 60.69% (982/1 618) and 1.92% (31/1 617), respectively. The HBsAg positive rate of vaccinated children (0.84%, 13/1 547) was lower than that of unvaccinated children (1/13) or children with unknown vaccination status (6.56%, 4/61) (χ² = 22.64, P < 0.001). The HBsAg positive rate (0.45%, 5/1 118) of the children with birth-dose given within 24 hours was lower than those that of children given beyond 24 hours (2.63%, 61/190) (χ² = 10.21, P < 0.001). The HBsAg positive rate (5/18) of children with birth weight under 2 kilogram was higher than that of children with birth weight above 2 kilogram (0.78%, 12/1 548) (χ² = 120.8, P < 0.001). The HBsAg positive rate of children born to HBsAg-positive mothers (2.80%, 3/107) was higher than that of children born to HBsAg-negative mothers (0.21%, 1/470) (χ² = 8.50, P = 0.004). With the age increasing, the coverage and timely birth-dose coverage of Hepatitis B vaccine (HepB) decreased, and the positive rate of anti-HBs gradually decreased.

CONCLUSIONAfter the catch-up vaccination was conducted in unvaccinated children aged 1-14 years from 2009 to 2011, the HBsAg and anti-HBc positive rate decreased, while the anti-HBs positive rate increased significantly.

OBJECTIVETo evaluate the outcome after endovascular aortic repair (EVAR) of abdominal aortic aneurysms (AAA) in single center.

METHODSA total of 711 AAA patients treated by EVAR in Department of Vascular Surgery, People's Liberation Army General Hospital and met the inclusion criteria from January 2004 to June 2014 were followed-up and analyzed. There were 612 male and 99 female patients, with a mean age of (69±13) years in this study group. The primary outcome of the study was all-cause mortality, secondary outcome included procedural data, intervention-related morbidity and secondary therapeutic procedures. The endpoint was death. Kaplan-Meier survival analysis were used to analyze long-term survival and cumulative probability of intervention related morbidity. Cox proportional hazards regression was used to analyze factors influenced the survival. Multivariable analysis were adjusted for covariates.

RESULTSThere were 74.8% of total patients followed up. The longest follow-up period was 10.4 years (mean 3.8 years). For the primary outcome of all-cause mortality, 140 deaths occurred. Intervention related morbidity was 9.3%, secondary therapeutic procedures was 5.3%.The Kaplan-Meier survival curve showed that cumulative survival is 78% (95% CI: 74% to 82%) in 5 years, 67% (95% CI: 61% to 74%) in 10 years and the cumulative probability of intervention related morbidity is 10.5% (95% CI: 7.3% to 13.7%) in 5 years, 19.3% (95% CI: 11.9% to 26.0%) in 10 years. Cox proportional hazards regression showed that age>75 years, American Society of Anesthesiologists classification III or IV, smoking, diabetes significantly increase the risk of long-term all-cause mortality, while hypertension significantly decreases the risk.

CONCLUSIONSLong-term outcome after EVAR of AAA in the study is similar to those advanced studies.The management of risk factors would improve the prognosis of these patients.
