Type 2 diabetes is a metabolic disease with increasing prevalence,which causes great socioeconomic burden.Intestinal flora is the microbiota located in the human intestines,which are participating in human growth and development,physiological procedures,or even pathogenesis as a closely connected environmental factor.There have recently been rapid progresses in the research on the relationship between intestinal flora and type 2 diabetes in the field of endocrinology and metabolism.In this article,we reviewed the overall framework and research progress in the relationship between intestinal flora and type 2 diabetes,aiming to shed some light on the future research about this topic.

Objective　To investigate the occurrence of postural hypotension (PH) in patients suffering from type 2 diabetes mellitus with or without hypertension (DMH or DM), and the relationship of PH and diabetic neuropathy, hyperinsulinemia and insulin resistance. Methods　A total of 30 cases of type 2 DM and 30 cases of DMH were included in this study. The blood pressure of all subjects were measured in supine and standing body positions respectively and PH was defined as a decline from supine to standing was ≥20 mmHg in systolic blood pressures (SBP). The concentrations of blood glucose and plasma insulin were measured to calculate the insulin sensitive index (ISI). Autonomic and peripheral function was determined by measuring the postural heart rates and the conduction speeds of superficial peroneal and communicating branch of peroneal nerves etc respectively. Results　Significant difference (P<0.01) was found in the occurrence of PH in the patients with DM (40%) and those with DMH (67%). The changes of postural blood pressure were more obvious in those with DM+PH and DMH+PH than in those with simple DM (P<0.01). The conduction speeds of newes were significantly lower in those with DMH+PH than with simple DM (P<0.05), but the occurrence of autonomic neuropathy had no difference between the 2 groups. There was no difference in postural heart rate, body mass index and blood glucose levels in fasting and 2 h after meal among the DM, DM+PH and DMH+PH groups. The concentrations of plasma insulin of those with DMH+PH were significantly higher, but their ISI significantly lower than those of the patients with DM respectively (P<0.01). The decline of postural SBP in patients with DMH+PH had a significantly positive correlation with their plasma insulin levels in fasting condition (r=0.689, P<0.01). Conclusion　The patients with DMH are more prone to PH compared with those only with DM and PH damages their peripheral nerves. Most of diabetic patients with PH suffer from obvious IR and hyperinsulinemia, and if with hypertension, the above metabolic disturbances are more severe.

Objective To explore pathogenic bacteria distribution and drug susceptibility testing results in children with purulent meningitis in Jinan area. Methods A total of 54 children with purulent meningitis were selected from January 2010 to December 2014, the cerebrospinal fluid smear and culture, according to the national standard of clinical inspection technology for bacteria isolation and identification by disc diffusion method for drug sensitive test were retrospectively analyzed. Results A total of 54 strains of pathogenic bacteria including 36 strains of gram-positive coccus, and 17 strains of gram-negative bacillus and one strain of suspected Neisseria meningitides were found. A total of 31 strains gram positive coccus is Streptococcus pneumoniae, and most gram-negative bacilli is E. coli. In the Gram-positive coccus, 61.3% was sensitive to penicillin, and more than 90% was sensitive to ceftriaxone and cefepime, 83.3% was sensitive to meropenem, 94.7% resistant to azithromycin, and 58.1% resistant to oxazocilline. In Gram-negative bacilli, 60% was sensitive to ampicillin sulbactam 71.4% was sensitive to cephalosporin , 57.1% was sensitive to ceftriaxone , 66.6% was sensitive to cefepime. Conclusions From cerebrospinal fluid cultured of purulent meningitis, Streptococcus pneumoniae and E. coli were major pathogenic bacteria in children with purulent meningitis in Jinan area.

OBJECTIVETo investigate the expression of transcription factor Sp1 in gastric cancer tissue and its correlation with prognosis.

METHODSSp1 expression patterns in specimens of 86 gastric cancers, 57 normal gastric tissues and 53 metastatic lymph nodes were detected by immunohistochemical method. The activity of Sp1 in the tumor and normal tissues was examined by electrophoretic mobility shift analysis (EMSA). The correlation between transcription factor Sp1 expression of tumors and patients' prognosis were statistically analyzed using Cox proportional hazard model.

RESULTSIn normal gastric tissue, Sp1 protein was predominantly expressed in the nuclei of cell located in the mucous neck region, but neither in the gastric pit cells with foveolar differentiation, nor in cells of the glandular epithelium with glandular differentiation. Strong Sp1 expression was also detected in tumor cells, but very weak or even no Sp1 expression in stromal cells or normal glandular cells surrounding the tumor. The median survival time of patients with negative, weak, and strong Sp1 expression was 43, 37, and 8 months, respectively (P < 0.01). Spl expression (P < 0.01) and stage (P < 0.001) were demonstrated as independent prognostic factor by multivariate analysis.

CONCLUSIONNormal and malignant gastric tissue are found to have its own unique Sp1 expression patterns. Sp1 expression may be used as an important survival predictor in human gastric cancer.

Objective To investigate the prevalences of the obesity and hypertension in southern mountain regions of Ningxia. Methods A cross-sectional study was conducted among a representative sample of 10 639 adults using questionnaires, physical examinations, and blood pressure measurement in southern mountain areas with a population proportionate sampling method. Results The prevalences of overweight,obesity,central obesity,high percentage of body fat,and hypertension were 33.53%,10.71%,19.50%,27.69%,and 31.57% respectively, which were 30.31%,9.62%,16.70%,24.90%,and 27.61% after age-adjustment in rural areas of Ningxia,and increased with aging(Ptrend<0.05). The prevalences of overweight,obesity,and hypertension were higher in males than those in females(P<0.05),and that of central obesity was higher in females than in males(P=0.003).The prevalences of hypertension in subjects with overweight, obesity, central obesity, high percentage of body fat were 38. 14%, 53.75%,52.69%,and 48.90%,respectively. Body mass index,waist circumference,and percentage of body fat were positively correlated with systolic and diastolic blood pressure(P<0.05). The multivariable logistic model revealed that the risk of hypertension in different types of obesity increased about 1.5 times. Conclusion There is high prevalence of obesity and hypertension among the adults in southern mountain areas of Ningxia. The prevalence of hypertension in obesity,central obesity,and high percentage of body fat is closed to or more than half of the population investigated.

Objective To investigate the correlation between iodine nutritional status and thyroid diseases in some areas of Ningxia. Methods The physical examination, questionnaire survey, and measurement of urine iodine, thyroid function, thyroid associated antibodies were performed, with thyroid ultrasonography in Jingyuan County, Xingqing District and Guyuan City, Ningxia Yinchuan City, totally including 2827 adults. Results The median urinary iodine of all subjects was 258. 7(76. 6-1506. 4) μg/L. The average level of urinary iodine in rural areas [203.3(64. 6-1154)μg/L] was lower than that in cities[340. 7(114. 8-1726. 1)μg/L, Z=19. 514, P>0. 01]. The average urinary iodine level was lower in people over 65 years old[234. 2(58. 9-2285. 4) μg/L, x2=6.449, P=0. 040]. Subjects in hypothyroidism group [232. 5(69. 2-1682. 3) μg/L] had the lowest average urinary iodine level, while hyperthyroidism group[331. 9(102. 4-1862) μg/L] turned to be the highest group( x2=15. 432, P>0. 01). Compared with the normal group, TPOAb and TGAb increased group had similar median levels of urinary iodine (P>0. 05). If compared with single nodule, multiple nodules group and the normal group's median levels of urinary iodine also had no significant difference(P>0. 05). Conclusion Iodine excess was found in the studied population in these areas of Ningxia.
