Using colon adenocarcinoma cell line HT-29 as testing material, adhesion test was carried out for 24 strains of Bifidobacteria isolated from dejecta of longevous people aged one hundred years. The results showed that all strains could adhere to colon adenocarcinoma cells HT-29, among which the strains of TTF, Z2, TZ5 and (J-1) showed higher adhesive capability. Thus these four strains of Bifidobacteria were further tested for their endurance to stomach acid and bile acid. The production of vitamin B by these bacterial were also tested. All these tests indicated that the strain of TTF has high ability to produce Vitamin B_(1), B_(2), B_(6), B_(12), The survival rate after the treatment under pH 3.0 for 120 min was 93.11%, at the same time, the strain TTF can survive after being treated with 2% bile acid for 24h.

To study the stimulation effect to the growth of Bifidobac te rium sp. A04, 4 kinds of oligosaccharide, 8 kinds of Chinese traditional medi cine and 4 kinds of food raw materials were used. The results indicates that so ya bean oligosaccharide is the most effective (P

Objective To assess the efficacy and safety of topical tacrolimus for erosive oral lichen planus (EOLP). Methods Literatures published up to December 2013 were searched from PubMed, Embase, CENTRAL, Chinese BioMedical Literature Database (CBM), and System for Information on Grey Literature in Europe (SIGLE). All randomized controlled trials (RCTs) of topical tacrolimus for EOLP which compared with other interventions or a placebo were considered in this Meta-analysis. Two researchers collected data independently. The assessment of methodological quality was based on Cochrane Handbook and the materials were analyzed with the software Revman 5.2.5. The primary outcome measures were the symptoms (e.g. pain, discomfort) complained by patients. The secondary outcome measures included the improvement rate of clinical signs assessed by the investigators and the incidence of adverse effects (e.g. clinical candidiasis). Results A total of 9 RCTs involving 476 patients were finally included. The pooled odds ratio (OR) of clinical improvement for topical tacrolimusvs. topical corticosteroids was 1.19 [95% confidence interval (CI): 0.64-2.22,I2: 44%]. Regarding to 0.1% tacrolimus and 0.03% tacrolimus, the pooledOR were 1.87 (95 %CI: 0.60-5.82) and 1.47 (95 %CI: 0.14-16.04) respectively in subgroup analysis. No serious adverse events were reported in topical tacrolimus group. Conclusions There was no evidence to support that topical tacrolimus for EOLP was more effective and safer than topical corticosteroids in this Meta-analysis. Clinical assessment criteria should be established and accepted by clinicians and researchers before further RCTs are undertaken.

Objective To investigate the relationship between abdominal aortic calcification (AAC) and outcomes in maintenance hemodialysis (MHD) patients. Methods One hundred and seventy MHD patients in the dialysis center of the Second Hospital of Tianjin Medical University from June 2014 and October 2014 were enrolled prospectively. Abdominal aortic calcification (AAC) was measured using AAC score (AACS) by abdominal lateral plain radiography. According to the AACS, the patients were divided into mild AAC (AACS<5) group and severe AAC (AACS≥5) group for comparison, and Kaplan?Meier analysis was used to compare their survival rates. Multivariable COX regression models were used to determine the risk factors of all?cause mortality and cardiovascular disease mortality in MHD patients. Results Severe AAC (AACS≥5) was present in 28.2%(48/170) patients. The median follow?up duration was 25.6 (22.0, 26.0) months. During the follow?up, 6 patients (4.9%) in AACS<5 group and 14 patients (29.2%) in AACS≥5 group died. Kaplan?Meier analysis showed that patients in AACS≥5 group had higher all?cause mortality rate and cardiovascular disease mortality rate as compared with patients in AACS<5 group (χ2=9.746 ,P=0.002; χ2=9.697 ,P=0.002). Multivariate COX regression analysis demonstrated that high AACS (HR=4.373, 95%CI 1.562?7.246, P=0.005) and hypoproteinemia (HR=0.886, 95%CI 0.797?0.985, P=0.025) were independent risk factors for all?cause mortality, while hypoproteinemia (HR=0.829, 95%CI 0.718?0.956, P=0.010) and low 1,25(OH)D3 (HR=0.769, 95% CI 0.627 ? 0.944, P=0.012) were independent risk factors for cardiovascular disease mortality. Conclusions AAC is significantly associated with overall survival in MHD patients. To further evaluate the relationship between AAC and outcomes in MHD patients, multi?center and long term follow up studies of large sample size are necessary.

In adipose tissues from sreater omentum of patients with type 2 diabetes,the mRNA and protein expressions of human rearranged immunoglobulin?light chain (HSIGVL) 022 were measured by the fluorescent quantitative RT-PCR and immunohistochemistry respectively.The results showed that mRNA and protein levels of HSIGVL022 were up-regulated in patients with type 2 diabetes.The mRNA level of HSIGVL022 was linearly correlated with insulin resistance index,suggesting that this gene may play a role in the pathogenesis of insulin resistance and type 2 diabetes.

Objectlve To detect the KChIP2 mRNA level in rheumatic heart disease patients with or without atrial fibrillation (AF) by real-time PCR.Methods Right atrial appendage samples from rheumatic heart disease patients with (n=17) or without AF (n=13) were obtained during cardiac surgery.Total RNA was extracted from the atrial tissues.and the KChIP2 and Kv4.3 mRNA were detected by SYBR Green I real-time PCR with the GAPDH as the house keeping gene.Result The ratio of KChIP2/GAPDH(0.1468 ±0.0452 VS.0.2200±0.0388,P＜0.01)and the ratio of Kv4.3/GAPDH(0.3946±0.1826 vs.0.5257±0.1427.P＜0.05)were significantly lower in AF patients compared to non-AF patients.Conclusion Down-regulated atrial KChIP2 and Kv4.3 mRNA expressions in rheumatic heart disease patients with chronic AF might be one of the molecular bases responsible for the down-regulation of the Ito current density of AF.

OBJECTIVETo study the clinical features of pediatric acquired immunodeficiency syndrome(AIDS).

METHODSThe epidemiological, clinical and laboratory data of 66 children with AIDS were retrospectively studied.

RESULTSOf the 66 patients, 46 (69.7%) were male and 20 (30.3%) were female, with a mean age of 8.7 years (ranged 2-16 years). The mean age at diagnosis was 7.7 years (ranged 2-15 years). Vertical transmission as the route of infection was documented in 48 cases (72.7%). Fourteen children (21.2%) were infected through blood or blood products. The route of infection could not be identified in 4 cases (6.1%). Body weight loss was noted in 43 cases (65.2%), anemia in 42 cases (63.7%), fever in 40 cases (60.6%), fatigue in 38 cases (57.6%), rash in 31 cases (47.0%), chronic cough in 28 cases (12.1%), chronic diarrhea in 24 cases (36.4%), CNS involvement in 16 cases (24.2%), oral thrush in 13 cases (19.7%), and hepatosplenomegaly in 12 cases (18.2%). Body height of 30 cases (45.4%) and body weight of 26 cases (39.4%) ranked the lower level. The immune system was severely suppressed in 59 cases (89.4%) and moderately suppressed in 7 cases (10.6%).

CONCLUSIONSVertical transmission remained the most common route of pediatric HIV infection. There were various clinical manifestations in children with AIDS. The immune systems of the majority of children with this disorder were severely suppressed.
