Objective To investigate the change of the content of suppressor of cytokine signaling (SOCS-1) in the liver of septic mice and its working mechanism.Methods Adopted Cecalligation and puncture (CLP) to create models of sepsis and divided randomly adult male BALB/c mice into 8 groups,including normal controlled group,sham-operated group,and the killed groups 2 hours,6 hours,12 hours,24 hours and 48 hours after operation.After extracting the RNA and protein from the liver tissue of the mouse groups,reverse transcription polymerase chain reaction (RT-PCR) was adopted to determine the relative content of SOCS-1 mRNA in the tissue,Western blot was adopted to determine the relative content of protein and the SPSS statistics software was adopted to calculate the correlation.Then observed the pathological change of liver tissues,and detected SOCS-1 protein expression by immunohistochemistry.Results After CLP suergery,the expression of SOCS-1 on gene degree in the liver and the expression of SOCS1 on protein degree in the liver increased rapidly at the 6th hour ( P ＜ 0.05 ),with the former reaching peak ( P ＜ 0.05 ) at the 24th hour and the latter remaining high all the time.There were pathological changes such as fatty degeneration and necrosis in the septic liver tissue,hepatic SOCS-1 protein expression could be detected by immunohistochemistry.Conclusions CLP induced sepsis could lead to the increase of the expression of SOCS1 in the liver.

Objective To investigate the expressions of transforming growth factor-?1(TGF-?1)and ?-smooth muscle actin(?-SMA)in the lungs of mice with intra-amniotic endotoxin priming and exposed to 60% hyperoxia after born in order to elucidate the possible relationship with bronchopulmonary dysplasia(BPD).MethodsFifty C57 pregnant mice were divided into 2 groups:lipopolysaccharide(LPS,40 ?g/L)group and saline solution group,and then received an intra-amniotic injection of corresponding solution on E15.The neonatal mice of each group were randomized to be set in 60% oxygen exposure or in room air.So there were 4 subgroups,LPS+air,LPS+hyperoxia,saline+air and saline+hyperoxia groups.On days 1,3,7,10 and 14 after birth(8 rats each time point),the lung histological changes was assessed with hematoxylin and eosin(HE)staining for radial alveolar counting(RAC).The expressions of TGF-?1 and ?-SMA proteins were detected by immunohistochemical and immunofluorescence staining,and the expressions of TGF-?1 and ?-SMA mRNA by real-time polymerase chain reaction(RT-PCR).ResultsIn the LPS+hyperoxia group and saline+hyperoxia group,RAC began to decrease on day 3,and then further declined in a time-dependent manner.Compared with saline+hyperoxia group,LPS+hyperoxia group had significantly lower RAC(P

Magnetic resonance spectroscopy (MRS) of cervical cancer can detect tumor related specific metabolic compounds such as choline,choline compounds,triglyceride,etc.MRS can be used in identification of benign or malignant lesions of cervix,diagnosis of cervical cancer and monitoring the efficacy of radiotherapy and chemotherapy,etc.It will make for the clinical diagnodis and treatment of cervical cancer.

Diffusion-weighted imaging (DWI) is sensitive to identification of cervical lesions and lymph node metastasis.DWI can be used to predict and evaluate the therapeutic effect of cervical cancer.Using magnetic resonance imaging and DWI scans in the process of diagnosis and treatment of cervical cancer,which may contribute to the personalized treatment program and improve prognosis for patients.

ObjectiveTo study the clinical features, arterial involvement, therapeutic strategies and outcomes of Takayasu arteritis (TA). MethodsThe clinical symptoms, arterial images, inflammatory parameters and follow-up information of 173 patients with TA were retrospectively studied. Comparisons between groups were performed by t-test. ResultsThere were 136 female and 37 male patients in this study. The mean age at onset was(26±11 ) years. Hypertension, pulse deficit or asymmetrical pulse, and fever were present in 46.6％, 41.1％, 28.7％ of patients, respectively. The distribution of arterial involvement were 64.7％in aorta, 9.8％ in pulmonary artery, 19.1％ in innominate artery, 65.9％ in common carotid arteries, 65.3％in the subclavian artery, 36.2％ in the renal artery, 12.1％ in the vertebral artery, and 5.8％ in coeliac axis.Elevated erythrocyte sedimentation rate(ESR) was found in 61.0％ patients. Active tuberculosis or history of tuberculosis was implicated in 45 patients(26.0％). Ten patients(5.8％) were hepatitis B virus carriers.Among 105 followed-up patients, 98 patients(94.2％) achieved persistent remission, 17 patients relapsed when corticosteroids were tapered. ConclusionCorticosteroids combined with or steroid alone, supplemented with endovascular intervention procedures or surgical bypass procedures when necessary, can effectively control the clinical symptoms and inflammatory parameters and improve the quality of life of patients.

· AIM: To inspect and compare the functional vision of an aspheric intraocular lens (Tecnis) with those of conventional monofocal silicone and acrylic intraocular lens and multifocal intraocular lens (Array).· METHODS: The IOLs were tested in the eye model, which was designed to be optically equivalent to the theoretical eye model. The eye model is a combination of a spherical photographic lens with 35mm focal length ( IOL put in a water cell)and a charge coupled device (CCD) camera. The images constructed by the lenses are observed on a monitor of personal computer and the contrasts of the images are analyzed by using commercial image processing software.· RESULTS: The modulation transfer function of the eye model equals the scale produced by the theoretical eye model. The images constructed by changing the diameter of aperture stop and IOL.· CONCLUSION: The proposed eye model is useful for testing functional vision and for inspecting differences of intraocular lens.
