Objective To search for the differences of serum proteins expression in ulcerative colitis (UC) by proteomics method and to preliminary explore the potential biological markers of ulcerative colitis. Method The serum of 30 ulcerative colitis patients and 30 healthy individuals were collected. The equal amounts of proteins in pooled serum were separated by two-dimensional gel electrophoresis (2-DE) and then compared and analyzed by image analysis software to recognize the differences of protein expression. Some spots of proteins with different expression were identified by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF-MS).Result There was no statistic significant in age, weight index, smoking and alcohol taking between UC group and control (P ＞ 0.05 respectively). Thirty-nine proteins with significant different expression between UC patients and healthy individuals were preliminary screened out. Nine of those spots were selected, after analyzed by MALDI-TOF-MS, it was found that the expression of haptoglobin, heat shock factor protein 2, receptor tyrosine kinase, aldehyde reductase,apolipoproteinC-Ⅲ, pericentriol material 1 increased in ulcerative colitis patients, keratinl, filamin A interacting protein 1 and tropomyosin 3 decreased. Conclusions With proteomics 2-DE and spectrometry methods, nine UC associated serum proteins were screened out and identified, which provide new molecular markers for the research of UC biological behavior.

Objective To observe the impact of ginkgo biloba extract(Ginaton) on nerve functioninpa-tients withdelayed encephalopathy after acute carbon monoxide poisoning(DEACMP). Methods 96 patients with DEACMP treated in our hospital from April 2011 to February 2017 were randomly divided into a control group and a study group. The control group received hyperbaric oxygen ,control of intracranial pressure ,and improvement of brain cell metabolism;while the study group receivedintravenous injection of Ginaton 70 mg(adding into 250 mL of 0.9% sodium chloride) once daily fora 2-week therapeutic course. MRIand EEGwere used forexamination in DEACMP patients within 24 h after onset and 14 days after treatment. Changes in MRI and EEG examination , clinical symptoms ,mini-mental state examination (MMSE) score ,Barthel index (BI),and Montreal cognitive assessment(MoCA)were assessed before and after treatment between the two groups. Results The therapy wasef-fective in 39 patients in the study group,with a total effectiveness rate of 81.25%;and in 29 patients in the control group,with a total effectiveness rate of 60.42%. There was significant difference between the two groups (χ2 =5.042,P = 0.025). Inadmission,there were no differences between the two groups in the abnormal signals of MRI,abnormal rate of EEG,and the scores on MMSE,BI,andMoCA(P>0.05). After a 14-day treatment,the abnormal signals of MRI,abnormal rate of EEG,andthe scores on MMSE,BI,and MoCA score were improved better in the study than in the control group(P < 0.05). The MMSE score was negatively correlated with disease severity in DEACMP patients(r=-0.832,P=0.000). Conclusions Early treatment with Ginaton can effectively improvethe cerebral lesions on MR,the abnormal rate of EEG,andthe scores on MMSE,BI,and MoCA. It has certain clinical efficacy.

Objective To investigate the relationship between soluble CD14-st (Presepsin)and assessment,prognosis in patients with acute paraquat poisoning (APP).Methods A total of 82 patients with APP treated in Emergency Department of Harrison International Peace Hospital Affiliated to Hebei Medical University from January 2013 to January 2016 were divied into three groups:mild poisoning group (n =20),moderate poisoning group (n =36)and severe poisoning group (n =26).According to the outcomes,patients were divided into survivor group (n =28)and non-survivor group (n =54).Another 50 healthy subjects were selected as control group.In control group,samples of 3 mL venous blood from 50 healthy subjects were collected for laboratory examination.Samoles of 10 mL venous blood from all patients were collected before and 72 hours,7 days after treatment to detect presepsin,C reactive protein (CRP), tumor necrosis factor α(TNF-α),interleukin-6 (IL-6)and interleukin-10 (IL-10).Before and 72 hours, 7 days after treatment,the change of Acute physiology and chronic health evaluation (APACHE)Ⅱscore and the outcomes in 28 days were observed.The variance analysis of repeated measures was used for comparison among multiple groups,and the t test was used to compare changes of detected biomarkers between two groups,and the outcomes in 28 days between two groups were compared with chi square test. Pearson correlation test was used to analyze the correlation between Presepsin in patients with APP and the survival rate.Results APACHE Ⅱ scores and the serum level of prespsin,CRP,TNF-α,IL-6 at admission and 72 hours,7 days after treatment in three poisoning groups were significantly increased compared with control group,IL-10 were decreased compared with control group (P <0.05 ),and there were significant differences in those biomarkers between moderate group and mild group,and between severe group and mild group,moderate group (P <0.05).At admission,72 h,7 d after admission,APACHEⅡscore and the serum levels of presepsin,CRP,TNF-α,IL-6 in non-survivor group were higher than those in survivor group,and IL-10 in non-survivor was lower than that in survivor group (P <0.05).The mortality rates of these 3 groups were 25.00%,69.44% and 92.31%,demonstrating significant differences among three groups (P <0.05).The AUCs were 0.862 and 0.731 for presepsin and APACHEⅡscore respectively at admission.The predictive capability of presepsin for 28-day mortality was superior over that of APACHEⅡscore (P <0.05).The level of serum presepsin in patients with APP was negatively correlated with the survival rate (r =-0.285,P =0.009).Conclusions The detection of prespsin has important clinical value in the severity assessment and prognosis in patients with APP.It is an important guidance for early therapeutic strategy.

Acupuncture at Baliao points for urinary incontinence has the advantages of obvious therapeutic effect, simple operation and few complications, which is mainly used for the treatment of urinary incontinence after stroke, urinary incontinence after spinal cord injury, stress urinary incontinence and urinary incontinence of bladder overactivity, etc. Urinary incontinence after stroke and spinal cord injury is a complication of disease, most of which are combined with acupuncture at Baliao points on the basis of primary disease treatment. The bladder meridian of foot-Taiyang has the characteristics of "entering the collateral brain" and "carrying spine to the waist". Baliao points can conduct induction along the bladder meridian to the sick site along the bladder meridian, and can play a certain therapeutic role in the treatment of the primary disease. Stress urinary incontinence and urinary incontinence of bladder overactivity can be regarded as independent diseases. Since Baliao points are located in the lumbosacral region which is close to the bladder, acupuncture can play a role in the near treatment of acupoints, improve the operation of bladder qi and blood, and the curative effect has a cumulative effect.
