[Analysis of microbial community of heat resistant microorganisms in Chinese herbal pieces].

To investigate the composition and diversity of heat resistant microorganisms in contaminated Chinese herbal pieces. Matrix-assisted laser desorption/ionization time of flight mass spectrometry (MALDI-TOF-MS) protein fingerprinting and 16S rRNA high-throughput sequencing of Illumina Miseq were used to analyze the heat resistant microbial community of 9 varieties of Chinese herbal pieces. Stem pieces (Spatholobi Caulis, Tetrapanacis Medulla, Stachyuri Medulla) showed highest detection rate and most species of contaminants; However fruit pieces (Schisandrae Sphenantherae Fructus) had the lowest detection rate and least species of contaminants; among root pieces, the detection rate and number of contaminants species were lower in Tuber Dioscoreae Persimilis and Rehmanniae Radix Praeparata. The heat resistant microbial community was mainly of Bacillaceae and Paenibacillaceae, and Bacillus showed the highest detection rate among them, followed by Brevibacillus, Paenibacillus, and Solibacillus. The rest genus in high-throughput sequencing analysis included Enterobacter, Brevundimonas, Leuconostoc, Methylobacterium, Dechloromonas, Pantoea, Klebsiella, and Erwinia. There were potential risk factors in heat resistant microbial community of Chinese herbal pieces, so we shall improve the microbial limit standard, strictly control the pathogenic bacteria in the product, and strengthen the supervision and management in production and circulation of Chinese herbal pieces.

[Effect of Lymphocyte/Monocyte Ratio on Clinical Features and Prognosis of Patients with Primary Gastrointestinal Diffuse Large B Cell Lymphoma].

OBJECTIVE: To analyze the effect of lymphocyte/monocyte ratio(LMR) on clinical features and prognosis of patients with primary gastrointestinal diffuse large B cell lymphoma(PGI-DLBCL). METHODS: The clinical data of 38 PGI-DLBCL patients with complete follow-up data in our hospital were analyzed retrospectively. The absolute lymphocyte count(ALC), absolute monocyte count(AMC) and LMR were counted by automating complete blood cell count statistics in newly diagnosed patients, and then the LMR cut off value was obtained by ROC curve. All patients were divided into ≤3.9 group and >3.9 group according to cut off value. RESULTS: Out of 38 patients 21 male and 17 female with a median age 55 old years (29-73 years), 7 cases died, the clinical B symptom occurred in 7 cases (18.4%); the pathologic type of 13 cases (34.2%) belonged to germinal center B-cell like, the primary gastral and intestinal DLBCL were observed in 18 and 20 cases respectively. The chisquare test showed that the LMR associated with of clinical stage and tumor size of PGI-DLBCL. The median survival time was 44 months (7-100 months), and 5-year overrall survival(OS) rate was 78.3% for 38 PGI-DLBCL cases. The univariate analysis showed that age (P=0.021), stage (P=0.012), IPI score (P=0.001), LDH level (P<0.001), tumor size (P=0.037) and LMR (P=0.026) all associate with the 5 years OS rate(%), and the difference was between them statistically significant, but the multivariate analysis showed that only clinical staging is independent risk factors for the OS. CONCLUSION: LMR shows an important effect on clinical features and prognosis of PGI-DLBCL.

[Study of pancreases ß-cell function in first-degree relatives of type 2 diabetes patients].

AIM: To investig the pancreases ß-cell function in no-diabetic first-degree relatives of type 2 diabetes mellitus( FDR) patients. METHODS: Collect T2DM first-degree relatives, and divided them into three groups:no-diabetes group with normal sugar tolerance (NGT); no-diabetes with abnormal sugar tolerance (IGT); new-confirmed T2DM. apart from that three group patients, 30 normal people with no-related disease risks were also collected as normal control (NC). All four groups of patients were experienced with intravenous glucose tolerance test (IVGTT) and counting the first phase of pancreases function by statistic AIR35 and insulin sensitive index (ISI). RESULTS: New-confirmed T2DM patients with the significantly abnormal statistic results about AIR3.5 and ISI, while NGT patients had the abnormal results compared with normal control group but better than T2DM patients. CONCLUSION: Compared with normal group patients, NGT group appeared decrease of pancreases first phase secretes and insulin resistance but not aggravate enough to induce type 2 diabetes.
