This study reported the analysis of plasma phospholipid metabolism of the rats and the pathological biomarkers between the type 2 diabetes model control group (MC) and the normal control group (NC). SD rats were randomly divided into 2 groups: NC and MC. To investigate state of plasma metabolite profiling in normal body, type 2 diabetes mellitus (T2DM) model group using UPLC-Q-TOF/MS which was used as analysis tool in this research. The compounds were identified by UPLC-Q-TOF/MS based on MS/MS fragment ions information, element composition in MassLynx 4.1 and the Lipid Maps database. The sign of two groups of samples in specific markers for screening was through a software package in R software (BioMark software). The results show that the pathological markers were mainly phosphatidylcholine (PC) and triglycerides (TG); the 2-acyl PC in the MC group was less more obviously than that in the NC group; high carbon number and high degree of unsaturation of the TG was reduced under the condition of type 2 diabetes. In the state of type 2 diabetes, metabolic changes occurred in rat plasma phospholipids obviously, which had a close relationship with the occurrence and development of T2DM.

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.

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.

ObjectiveTo investigate the clinical features and risk factors of patient with Wegener's granulomatosis complicated with pulmonary infection.Methods Patients with Wegener's granulomatosis admitted to our hospital in the past 11 years were retrospectively analyzed.Comparisons between groups were performed by t tests or Fisher test.ResultsPulmonary infection occurred in 27 cases with an incidence rate of 29％.Twenty-six percent of pulmonary infections occurred at the initial diagnosis,and 44％ occurred within 6 months,while 30％ occurred later than 6 months.The clinical manifestations of pulmonary infection were productive cough (89％),hemoptysis (63％),fever and fatigue (56％),chest pain and pactoralgia (33％).The most common causative pathogen were bacteria(59％ ),fungi(37％ ),and tubercle bacillus(37％ ).Sinus infection(P=0.01),hypoproteinemia(P=0.03),hypoimmunoglobulinemia (P=0.007),and methylprednisolone pulse therapy(P=0.002) were the risk factors for pulmonary infection.ConclusionThe occurrence of Wegener's granulomatosis complicated with pulmonary infection is high within 6 months.The most common clinical manifestation is productive cough.The most common causative pathogens are bacteria,tubercle bacillus and fungi.Sinus infection,hypoproteinemia,hypoimmunoglobulinemia,and methylprednisolone pulse therapy are risk factors of pulmonary infection.

Objective To investigate the sleep quality and life quality of soldiers in a navy warship troop, and to explore the correlation between sleep quality and life quality and their influencing factors. Methods Random cluster sampling method was used to select navy soldiers from a navy warship troop. The subjects were surveyed by Pittsburgh sleep quality index (PSQI) scale and World Health Organization Quality of Life-Brief scale (WHOQOL-BREF). Results A total of 160 questionnaires were sent out and 154 valid questionnaires were returned (response rate 94.6%). Of 154 subjects, 31.8% (49/154) had good sleep quality, 53.2% (82/154) had moderate sleep quality, and 14.9% (23/154) had poor sleep quality. The soldiers with good sleep quality had significantly higher scores than those with poor sleep quality in physical, psychological, social and environmental domains of life quality (P0.05 or P0.01). Total PSQI score and most of scores of 7 parts of life quality, including subjective sleep quality, sleep latency, sleep time, sleep disturbances, hypnotic drugs, daytime dysfunction and sleep efficiency, were negatively correlated with the scores of 4 domains of sleep quality. There was significant difference in sleep latency of the subjects with the educational level of junior high school, senior high or polytechnic school, junior college, undergraduate college, or graduate degrees (F＝5.368, P0.01), and the subjects with junior college degree had the highest score of sleep latency, while those with undergraduate college degree had the lowest score of sleep latency. Soldiers had a higher score of sleep latency than the officers (t＝2.069, P＝0.040). There was significant difference in the social domain scores of life quality between navy servicemen with military service time 8 years, 3-8 years and ≤2 years (F＝3.401, P＝0.036). Officers had a higher score of social domain than soldiers (t＝－2.093, P＝0.038). Conclusion The sleep quality of navy servicemen should be improved. Improving sleep quality can effectively ameliorate life quality. The sleep quality and life quality of navy servicemen are related to educational levels, work categories and military service time. The corresponding psychological and behavioral intervention should be carried out according to the characteristics of different personnels.
