Objective To investigate the pulmonary imaging findings and the clinical characteristics of ANCA-associated vasculitis.Methods 16 patients with ANCA-associated vasculitis confirmed by pathology in our hospital were analyzed retrospectively,all patients underwent 1 6-sclice high resolution chest CT scans.The clinical manifestations and lung CT findings of the patients were analyzed.Results The mean age of 1 6 patients (7 male and 9 female)was 62.7 (ranged from 56 to 83).The onset time of the disease was ranged for 1 weeks to 2 years,and it was characterized as multiple organs involvement accompanied by kidney damage with different degrees.The clinical respiratory symptoms inluded fever and cough.The lung HRCT features of ANCA-associated vasculitis were as follows:patchy shadow in 14 cases (87.5%),streak one in 12 (75%),nodular one in 3 (18.8%),cavities in 4 (25%),emphysema and pulmonary bullae in 6 (37.5%),tree-in-bud in 6 (37.5%),pleural effusion in 4 (25%),mediastinal lymph nodes enlargement in 3 (18.8%), pleural thickening in 6 (37.5%),cellular-like in 5 (31.3%),bronchiectasis in 6 (37.5%),round-glass opacity in 10 (62.5%)and reticulate changes in 8 (50%).Some patients were treated by the glucocorticoid (a hormone steroid)or by it in combination with immunosuppressant, and the clinical symptoms were improved and some lesions on X-ray images were significantly reduced or disappeared.Conclusion ANCA-associated vasculitis usually occurs in the majority of middle or old age without gender difference.Multiple organs are easily involved and the lesions in lung may be misdiagnosed as infection.Early CT diagnosis and timely treatment may improve the prognosis.

Objective To analyze the possible risk factors for Parkinson's disease (PD),and to provide clues to its etiology and prevention.Methods A matched case-control study,including 91 cases of PD and 364 controls,was carried out in Shanxi Provincial People's Hospital.Subjects completed an interviewer administered questionnaire about some putative risk factors.Multivariable conditional Logistic regression model was used to analyze the associated factors for PD.SAS 8.0 was used to analyze the data.Results 6 risk factors were found significantly associated with PD.The odds ratio (OR) of Parkinson's disease was 5.421 (95％CI:1.272-23.103) for family history,3.330 (95％CI:1.268-8.741) for rural living more than 10 years,2.495 (95％CI:1.044-5.961) for maternal smoking during pregnancy,1.607 (95％ CI:1.224-2.112) for maternal age more than 37 years,3.673 (95％CI:1.766 7.643) for history of drinking alcohol,2.147 (95％CI:1.279 3.602) for less physical exercising.Conclusions PD is a disease affected by the interaction of genetic and environmental factors,and the risk factors should be intervened selectively.

Lung cancer is the leading cause of morbidity and mortality of malignant tumor.Surgery,radiotherapy and chemotherapy remain the primary means of treatment for lung cancer,while the discoveries of molecular targets and targeted agents for lung cancer are making revolutionary changes and will almost certainly propel progress in this field into the foreseeable future.Biomarker-based individualized comprehensive treatment strategy is expected to benefit the lung cancer patients' survival.Meanwhile,chemotherapy remains the major treatment of advanced non-small cell lung cancer,which requires implementing the "three combinations" dialectical therapy principles,that is,systemic with local,conventional with personalized,eliminating with supporting.

Objective: To investigate the changes of oxygen metabolic parameters and blood glucose concentrations during perioperative period of orthotopic liver transplantation. Methods: The blood gas, cardiac index (CI), mixed venous oxygen saturation (SvO2), oxygen delivery (DO2), oxygen consumption (VO2), oxygen extraction rate (O2ER), and arterial blood glucose were measured at defined time points (before anesthesia induction, 30 min before anhepatic period, 5 min after anhepatic period, 30 min after anhepatic period, 5 min of neohepatic period, 30 min of neohepatic period, and postoperation) in 50 patients receiving liver transplantation. Results: Compared with those before anesthesia induction, no significant changes in CI, SvO2, DO2, VO2, and O2ER were found in pre-anhepatic period. CI, VO2, and DO2 decreased significantly at the early 5 min of the anhepatic period (P<0.05); VO2, DO2, and O2ER decreased significantly at the 30 min of the anhepatic stage (P<0.05). SvO2, DO2, and VO2 increased, but O2ER decreased significantly at the early 5 min of the neohepatic stage (P<0.05). DO2, VO2, and O2ER increased significantly at the 30 min of the neohepatic stage (P<0.05). During preanhepatic stage the blood glucose levels increased progressively but were lower than those during anhepatic stage. During neohepatic stage, blood glucose decreased abruptly but was still higher than the normal level (P<0.05). Conclusion: It suggests that serious imbalance of oxygen metabolism exists during liver transplantation, especially in anhepatic and early neohepatic stages. Blood glucose increases during the preanhepatic stage, reaches the peak during the anhepatic stage, and then decreases gradually.

OBJECTIVETo investigate the role of RLIP76 in regulating multi-drug resistance in small cell lung cancer (SCLC), and to analyze the relationship between its expression and prognosis.

METHODSThe expressions of RLIP76 protein and gene were detected by Western blotting and real-time PCR (RT-PCR) in both the chemosensitive SCLC H69 cell line and chemoresistant H69AR cell line, respectively. siRNA was transfected into the H69AR cells to inhibit RLIP76 expression, and eGFP-RLIP76 was transfected into the H69 cells to enhance RLIP76 expression. The drug-sensitivity of cells to chemotherapeutic drugs (ADM, DDP, VP-16) were detected by CCK8 assay. The expression of RLIP76 in the SCLC tissues was detected by immunohistochemistry. The relationship of RLIP76 expression with clinicopathological features and prognosis of the patients was analyzed.

RESULTSThe expression of RLIP76 in H69AR cells was 13.675 ± 0.983, significantly higher than 1.074 ± 0.107 in the H69 cells (P < 0.01). The drug-sensitivities of H69AR cells to chemotherapeutic drugs were significantly increased when the expression of RLIP76 was down-regulated (P< 0.001). The sensitivities of H69 cells to chemotherapeutic drugs ADM, DDP and VP-16 were significantly decreased after transfection with eGFP-RLIP76 up-regulating the RLIP76 expression (P = 0.003). The positive expression rates were 61.3% and 9.4% in the SCLC tumor tissues and para-cancerous tissues, respectively (P < 0.01). The expression of RLIP76 was significantly correlated with clinical stage, chemosensitivity and overall survival of the SCLC patients (P < 0.05).

CONCLUSIONSOur results suggest that RLIP76 is involved in the regulation of small cell lung cancer multidrug resistance. RLIP76 may serve as a potential target gene to evaluate the chemosensitivity and clinical prognostic for small cell lung cancer.

Objective To screen key genes related to deep vein thrombosis (TDVT) after trauma using gene function assembly analysis. Methods Thirty Sprague Dawley rats were randomized into control, thrombosis and non-thrombosis groups. Traumatic limb DVT models were established in rats through quantitative beating on the bilateral posterior limbs. The Genechip Rat genome 430 2. 0 genechips were applied to detect changes in genes expressions on difference phases of DVT. On the basis of the differential gene expressions in the thrombosis and non-thrombosis groups, the gene function assembly analysis was conducted to define the most significant and concentrated gene functions leading to the biological characters of DVT.Results B factor (bf), complement 4 binding protein α (C4bpα), plasminogen activator inhibitor 1 (serpinel), urokinase-type plasminogen activator receptor (plaur) were screened to be the key genes related to DVT, because they were found to be involved in the functions like complement activation, development,growth, morphogenesis, primary metabolism, cell motility, protein metabolism, localization of cell, locomotion and localization. The abundance values of the genes expressed were 1.6, -0. 2, 2. 1, 5. 1 in the thrombosis group, and -0. 5, - 1.4, 2. 7, 3. 3 in the non-thrombosis group. Conclusion Bf, C4bpα,serpinel, plaur may be the key genes that play a role in the process of DVT.
