Objective To analyze the prevalence season and trend of meningococcal disease in China by epidemic years from 2004 to 2008 in order to provide scientific basis for making strategies of meningococcal disease prevention and control.Methods The incidence numbers of meningococcal disease were calculated by weeks,epidemic years and areas.The seasonality and prevalence trends of meningococcal disease were analyzed by circular distribution.Results The incidence trend of meningococcal disease had obvious seasonality in China (P

Objective To analyze the correlation between miR-31 and ESCC in expression of miR-31 in the plasma of ESCC in Xinjiang Kazak and Han nationality patients. Methods The plasma samples were collected respectively from patients with ESCC in 20 cases and healthy subjects in 20 cases. The relatively expression of miR-31 was detected by real-time Q-PCR. Results The expression of miR-31 with ESCC were higher than those of the normal control group, which related to the degree of tumor differentiation in Kazak ESCC patients (P < 0.01); the levels of miR-31 relative expression in Kazak were higher than that of Han (P = 0.008, P = 0.027). Conclusion miR-31 may be involved in the occurrence of ESCC in Han and Kazak nationality. miR-31 might be another risk factor in high incidence of ESCC in Kazak than Han nationality.

Objective Preoperative autologous blood donation ( PABD) may reduce the need for allogeneic blood , but it may also cause a short massive blood loss in pregnant women , and its fetal and maternal safety has to be adequately assessed .This study was to evaluate the feasibility and safety of PABD for pregnant women and their fetuses . Methods A prospective observational study was conducted among the women who met the inclusion criteria and gave birth in Nanjing Drum Tower Hospital between January and December 2013 .According to the clinical validation of risk stratification criteria for peripartum hemorrhage of California 2013 , the ca-ses were classified into a low-, a medium-, and a high-risk group.Data on blood donation procedures , obstetric outcomes, and blood transfusions were collected after delivery for analysis . Results Totally, 92 pregnant women accomplished 115 blood donations .The median volumes of the donated blood were 300, 300, and 400 mL in the low-, medium-, and high-risk groups, respectively ( P>0.001).There were no significant changes in HR , SBP and SpO2 during the blood donation procedures (P>0.05) except for the fall of diastolic blood pressure by an average of 3.4 mmHg (P<0.05) at 5 minutes after blood collection, which was restored to normal later.Non-reassuring fetal heart rate patterns were not found in any of the cases .The levels of HB and HCT were remarkably lower af-ter donation than before it (P<0.05) but restored to normal before delivery in the PABD cases who donated once only (P>0.05), which were similar to those in the cases who donated twice , with no significant differences before and after the donation (P>0.05). Homologous blood transfusion was performed for 5 cases (17.9%) in the high-risk group, with the volume of blood loss >2000 mL in all the cases.All the newborns survived without asphyxia and there was no perinatal death . Conclusion PABD can provide timely autologous whole blood donation for pregnant women .Under strict management , PABD is feasible and safe for pregnant patients who are at a high risk for massive blood loss during delivery or have a rare type of blood no readily available .

AIM: To investigate in vitro effects of cholecystokinin octapeptide(CCK-8) on the expressions of B7.1 and B7.2 and the costimulatory activity of T lymphocytes in unstimulated macrophages.METHODS: Mouse peritoneal macrophages were isolated and incubated with CCK-8(10-12-10-6 mol/L) for indicated time.The B7.1 and B7.2 expressions of murine peritoneal macrophages were analyzed by flow cytometry.CD4+T cells were isolated from mouse spleen using immunomagnetic beads,and cultured with 1/4 numbers of macrophages which were pretreated with CCK-8 and/or anti-B7.1 antibody,anti-B7.2 antibody,CCK1R antagonist CR1409,CCK2R antagonist CR2945 for 24 h.ConA was added into the culture medium to stimulate CD4+T cell proliferation.The proliferation was determined by measuring -TdR incorporation in a ?-scintillation counter.RESULTS: B7.1 and B7.2 expressions and costimulatory activity of peritoneal macrophages were enhanced by CCK-8 in a dose-dependent manner,and the maximal effects occurred at the concentrations of 10-9 mol/L to 10-7 mol/L.Anti-B7.2 antibody,but not anti-B7.1 antibody,reduced the modulatory role of CCK-8 on costimulatory activity.Both CR1409 and CR2945 reversed the effect of CCK-8 on costimulation,and the role of CR1409 was more significant.CONCLUSION: CCK-8 enhances macrophage costimulatory activity by upregulating B7.2 expression,which is mediated by CCK1R and CCK2R.CCK1R might be the major receptor responsible for the modulation of CCK-8 on costimulation.

OBJECTIVETo detect potential mutations of PHEX gene in four pedigrees affected with hypophosphatemic rickets (HR) and provide prenatal diagnosis for a fetus at 13th gestational week.

METHODSThe coding regions and exon/intron boundaries of PHEX, FGF23, DMP1, ENPP1, CLCN5 and SLC34A3 genes of the probands were analyzed by targeted next-generation sequencing (NGS). Suspected mutations were verified by Sanger sequencing among unaffected relatives and 200 unrelated healthy individuals. Deletions were confirmed by multiplex ligation-dependent probe amplification (MLPA) detection of probands, unaffected relatives and 20 unrelated healthy individuals. Prenatal diagnosis for a fetus with high risk was carried out through MLPA analysis.

RESULTSFour PHEX mutations were respectively detected in the pedigrees, which included c.850-3C>G, exon 11 deletion, exon 13 deletion and c.1753G>A (p.G585R). Among these, exon 11 deletion, exon 13 deletion and c.1753G>A (p.G585R) were novel mutations and not found among unaffected relatives and healthy controls. In pedigree 3, the same mutation was not found in the fetus.

CONCLUSIONMutations of the PHEX gene probably underlies the disease among the four pedigrees. NGS combined with Sanger sequencing and/or MLPA detection can ensure accurate diagnosis for this disease.

OBJECTIVETo compare the predictive value of liver enzymes and alcohol consumption for determining risk of type 2 diabetes (T2DM).

METHODSA cross-sectional study was conducted in Zhengzhou with a total of 2, 693 men.Participants' height, weight, and histories of smoking and drinking were recorded. Levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), gamma-glutamyl transferase (GGT) and blood glucose, as well as related metabolic indexes were detected.

RESULTSModerate daily alcohol consumption (more than 35 g ethanol/week and less than 140 g ethanol/week) decreased the risk of type 2 diabetes (OR =0.376, 95% CI:0.306 -0.463, P less than 0.05) but increased risk for higher levels of GGT and ALT (OR GGT =3.012, 95% CI:2.357-3.849, Pless than 0.01; ORALT =1.473, 95% CI:1.043-2.081, Pless than 0.05). In joint analyses of alcohol consumption and liver enzymes, the group of nondrinkers/light drinkers (less than or equal to 35 g ethanol/week) in the fourth quartile of GGT levels had the highest risk for type 2 diabetes (OR =12.219, 95% CI:6.217-24.016, P less than 0.01). The relationship of ALT and daily alcohol consumption with the risk of type 2 diabetes was almost the same as that of GGT (nondrinkers/light drinkers in the fourth quartile of ALT levels (OR =5.357, 95% CI:3.070-9.350, P less than 0.0 1).

CONCLUSIONGGT, ALT and daily alcohol consumption were independently associated with risk of type 2 diabetes. Nondrinkers/light drinkers with the highest levels ofGGT orALT were at high risk of type 2 diabetes.

Objectives To explore acute meningitis and encephalitis syndrome (AMES) surveillance in 4 China prefectures, to understand the epidemiological features and disease burden of neisseria meningitides (Nm) meningitis, streptococcus pneumoniae (Sp) meningitis, haemophilus influenza type b (Hib) meningitis and Japanese encephalitis and provide evidence for related disease prevention and control. Methods AMES surveillance were conducted in Jinan, Shandong Province and Yichang, Hubei Province in September 2006, and in 13 districts of Shijiazhuang, Hebei Province and Guigang City, Guangxi Zhuang Autonomous Region in April 2007. Six hospitals in each city were selected as monitoring pilot hospitals to carry out reports of suspected cases of acute meningitis and encephalitis, case investigation, blood specimens and cerebrospinal fluid specimen collection, anti?JEV IgM antibody enzyme?linked immunosorbent assay, Nm, Sp and Hib culture and polymerase chain reaction detection, etc. According to the age group, the incidence of bacterial meningitis and Japanese encephalitis in local residents<20 years old was estimated. Results From 2006 to 2013, a total of 19 423 surveillance cases were reported in four cities, of which 11 071 (56.99%) were reported in the pilot hospitals. Of the 11 071 cases, 5 315 were tested for bacteriology and 9 180 were tested for anti?JEV IgM antibodies. Among the bacteriological tests, 176 cases were positive, including 75 cases of Nm positive, 91 cases of Sp positive and 10 cases of Hib positive. The incidence of three bacterial meningitis is estimated for people under 20 years old, with estimated incidence of Nm, Sp and Hib meningitis in children <5 years old was 0.46/100 000-0.71/100 000, 0.34/100 000-0.83/100 000 and 0.32/100 000-0.57/100 000 respectively; the estimated incidence of Nm and Sp meningitis in children aged 5-9 years was 0.59/100 000-1.14/100 000 and 0.50/100 000-1.66/100 000 respectively. In 732 cases of positive JE cases, the positive detection rates of<5 years old, 40-49 years old and ≥50 years old were 9.51% (95/999), 28.09% (66/235) and 33.85% (130/384), respectively. The estimated annual incidence rate of JE was 0.12/100 000-0.79/100 000.ratio of cases 1.19∶1. Most of cases (27.30%) were children and adolescents aged 5-14 years and those (26.84%) aged over 45 year. Conclusion The study found that primary and secondary school students are the key population of Nm meningitis, suggesting that it is necessary to explore the enhanced immunization study of meningococcal vaccine in this population; Sp has the possibility of occurrence in all age groups;<5 years old children are the main population of Hib meningitis.

Due to the difference of cultural background, the psychological, social and spiritual needs of dying people are very different, so there are great differences in the care and nursing concept of dying people in different countries and nationalities. In order to construct the modern hospice care, we should actively learn from the western experience, but more important is to dig the local ideological resources from the traditional culture, build a set of caring care theory and practice rooted in China and originated from the concept of a good end of Chinese traditional culture, with the characteristics of the times and the cultural confidence of the Chinese nation, serving the Chinese people, and with Chinese characteristics.
