Objective To observe the effect of new moist dressings on pressure ulcers after spinal cord injury. Methods 58 spinal cord injured patients complicated with pressure ulcers were divided into observation group (n=29) and control group (n=29). The observation group accepted moist dressings, while the control group accepted routine dry dressings, TDP and ultraviolet irradiation. The incidence of im provement were recorded 2 weeks after treatment, and the time of healing were compared. Results 11 cases cured, 17 cases relieved in the observation group, and it was 5 and 18 cases in the control group, respectively (P<0.05). It spent (26.69±16.48) days to cure in the observa tion group, and (38.24±22.47) days in the control group (P<0.05). Conclusion The moist therapy may promote the cure of pressure ulcers af ter spinal cord injury, and shorten the time of cure.

Alzheimer′s disease ( AD) is the most common disease leading to dementia .With aging of the population , the morbidity of AD is increasing significantly , which brings serious burden personally and socially .So the early diagnosis of AD has be-come the hotspot in the current research field .In order to highlight new ideas for the early diagnosis of AD , the current review will ana-lyze from the first international diagnostic criteria for AD dementia to the latest conceptual framework for research on subjective cogni -tive decline in preclinical Alzheimer′s disease.

Objective To analyze the diagnostic significance of the expression of perinuclear anti-neutrophil cytoplasmic antibody(pANCA) and anti-Saccharomyces cerevisiae antibody(ASCA) in the patients with inflammatory bowel disease(IBD).Methods Serum samples were collected from 97 patients with IBD,including 86 patients with ulcerative colitis(UC) and 11 with Crohn′s disease(CD).Another group of 36 persons in whom colonoscopic examination was negative served as control.Determinations of ASCA and pANCA were performed using indirect immunofluorescence test(IIFT).Results The positive rate of pANCA in group UC,CD and control was 27.9%,0% and 0%,respectively.Obviously,the rate in group UC was higher than that in the other two groups(P0.05).Four of 11 CD patients(36.4%) were severe cases,among them 3 showed ASCA+;7 were moderate cases(63.6%),and among them 1 case showed ASCA+.The positive ratio of ASCA was significantly different between severe and moderate CD cases(P

Objective To evaluate the changes and significances of malondialdehyde(MDA)and Superoxide dismutase(SOD)in unstable angina pectoris(UAP)patient after percutaneous coronary intervention(PCI). Methods MDA and SOD were tested in 25 UAP patients before and 1h,24h,72h after PCI.20 UAP patients who were performed on coronary angiography(CAG) and 20 normal individuals entered this study as contrasts.All the UAP patients were followed up for 3 months。 Results Level of MDA in UAP cases significantly increased compared with the normal individuals, P

Objective To verify the traditional serrated pathway by comparing microsatellite instability(MSI) status among traditional serrated adenoma, traditional adenoma, serrated colorectal cancer and non-serrated coloreetal cancer. Methods Seventy-five paraffin-embedded tissue samples, including 15 with serrated adeneearcinoma (Sca), 20 with non-serrated adenocareinoma (N-Sca), 20 with traditional serrated adenoma(TSA) and 20 with villous adenoma(AD) were collected from the pathology department of our hospital. Genomic DNA was extracted from these samples and then amplified with fluorescently-labeled primer specific for BAT25 and BAT26. The MSI status was detected with DNA automatic sequencer. Results Six of 18 samples with TSA harbored MSI-H and twelve MSI-L/MSS; 18 samples with conventional adenoma were exclusively of MSS; 3 of 13 samples of serrated carcinoma harbored MSI-H and ten MSI-L/MSS; 18 of 19 N-Sca samples harbored MSI-L/MSS and only one MSI-H. With Chi-square test, the MSI frequency in AD group and N-Sca group was significantly lower than that in TSA group and Sca group ( P < 0. 05 ) ; but with no statistical difference between the TSA group and Sca groups ( P > 0. 05 ). Conclusion MSI-H frequency in AD group and N-Sca group was obviously lower than that of TSA group and Sca group. It is concluded that there might be a new traditional serrated neoplasia pathway which is different from the conventional adenoma-carcinoma carcinogenesis pathway, but we still need prospective follow-up studies to verify its existence.

Assessment of left ventricular function is an important part of the function of whole cardiac.Two-dimensional speckle tracking imaging technology can track single pixel and get its trajectory,thus we can fully knowledge the function of left ventricular.At present,a large number of clinical studies have confirmed the significance of two-speckle tracking imaging in the evaluation of left ventricular function,and the details were reviewed in this article.

A total of 175 patients with type 2 diabetes mellitus (T2DM) were composed of 69 with normoalbuminuria,60 with microalbuminuria,and 46 with macroalbuminuria.The control group consisted of 64 healthy individuals.Serum YKL-40 levels were determined with ELISA method and related metabolic data were collected.Serum YKL-40 levels were significantly higher in T2DM group than in control group(P＜0.01).Significant correlations of YKL-40 were found with the ratio of microalbuminuria to uric creatinine(r=0.677,P＜0.01),HbA1C (r =0.562,P＜0.01),systolic blood pressure (r =0.372,P =0.001),HOMA-IR (r =0.460,P =0.001),low density lipoprotein-cholesterol (r=0.304,P=0.012),age(r=0.260,P=0.015),blood uric acid (r=0.329,P=0.018),and high density lipoprotein-cholesterol (r=-0.247,P=0.032).YKL-40 may play a role in the occurrence and development of diabetic nephropathy.

Objective To detect the expression of T cell immunogloblin and mucin domain-containing molecule 3 (Tim-3) mRNA in peripheral blood mononuclear cells (PBMC) isolated from asthmatic children and asthmatic murine,and to explore the role of Tim-3 in bronchial asthma.Methods Recruiting 97 cases asthmatic children,47 children with acute asthma exacerbation(acute attack group),50 children with asthma remission (remittent group)and 42 children as the healthy control group.The Tim-3 mRNA expression was measured by using reverse transcription-polymerase chain reaction(RT-PCR) method.The levels of interleukin-6 (IL-6) and transforming growth factor-5 (TGF-β)were determined with enzyme-linked immunosorbent assay (ELISA),and to analyze the correlation between Tim-3 mRNA and the level of IL-6.The asthmatic murine models were randomly divided into 2 groups:normal control group and asthma group.There were 10 mice in each group.PBMC in each group were collected.Expression of Tim-3 mRNA was detected by using real-time PCR.The level of CD4 + IL-17 + and CD4 + CD~ + FoxP3 + which reflected Th17 and regulatory T cells(Treg) expression respectively were detected by using flow cytometry,and the correlation between Tim-3 and Thl7/Treg level was analyzed.Results Expression of Tim-3 mRNA in children with acute asthma exacerbation was significantly higher than those in remission stage and healthy control group (all P ＜ 0.05).The expression of Tim-3 mRNA in children with asthma remission was significantly higher than that in healthy control group (P ＜ 0.05),and the level of IL-6 in children with acute asthma exacerbation was significantly higher than those in remission stage and healthy control group (all P ＜ 0.05).In the murine model of asthma group,the level of Tim-3 mRNA in PBMC was significantly higher than that in normal control group (P ＜ 0.01),and in asthma group CD4 + IL-17 + expression was significantly higher than normal control group but CD4 + CD25 + FoxP3 + was significantly lower than that in normal control group (all P ＜ 0.05),and the ratio of Th17/Treg increased in asthma group compared with normal control group (P ＜ 0.05).Tim-3 mRNA expression in PBMC was correlated positively with CD4 + IL-17 + level and Th17/Treg ratio respectively (all P ＜ 0.05),but was correlated negatively with CD4 + CD25 + FoxP3 + level(all P ＜ 0.05).Conclusions The high level expression of Tim-3 mRNA in asthmatic children participated in the airway inflammation,which is associated with IL-6,and animal experiments indicating that Tim-3 is closely related with the imbalance of Th1 7/Treg,indicated that Tim-3 may play a certain role in asthma.

Along with the development of biomarkers, the diagnostic criterion for early AD is continuously progressing until the preclinical stage of AD, on the base of which, the conception of subjective cognitive decline was raised.In order to highlight new ideas of the early diagnosis for AD in its preclinical stage, the current paper will talk about SCD in connection with neuroimaging tech-niques and examination of cerebrospinal fluid.
