Objective The purpose of this study was to explore the impact of consistency primary nursing model on improvement of obstetric nursing care quality.Methods The sample consisted of 230 postpartum women in the intervention group and the other 240 postpartum women in the control group of non-intervention.The intervention is the use of new model of consistency primary nursing.Women finished the scale of overall patient satisfaction before their delivery.The other data of obstetric nursing care quality score were collected by study staff for three months.Data were analyzed using t test.Results Score of patients' overall satisfaction and obstetric nursing care quality in the invention group were much higher than that of the control group except for first-aid articles and disinfection and isolation.Conclusions The consistency primary nurs-ing model resulted in higher satisfaction and nursing care quality standard.It is suggested to extend this new nursing model in most maternity and infant hospitals and other general hospitals.

Objectives Tostudytheexpressionchangesofproproteinconvertase1(PC1)incerebral cortex nerve cells and its substrate neuropeptide Y (NPY)after focal cerebral ischemia in mice and to investigatetheeffectofPC1inneuronalischemicinjury.Methods Twenty-fourmaleC57micewere randomly allocated into a sham-operation group,an ischemia-reperfusion 4-or 24-hour group with computer (n=8 in each group). A rat model of middle cerebral artery occlusion was induced by the intraluminal suture method. Western blot and real-time quantitative nucleic acid amplification were used to detect the expression changes of PC1,NPY,and mRNA in mouse cortical neurons. Results (1)Compared with the sham operation group,the expression of PC1 mRNA of ischemic cortex brain tissue at ischemic side in the ischemia-reperfusion 4-hour group increased 2. 66 ± 0. 24 and in the ischemia-reperfusion 24-hour group expressed 2. 07 ± 0. 23 (all P<0. 05). Compared with the sham operation group,the PC1 precursor protein level increased significantly at 4 hours (P<0. 05). There was no significant difference in the 24-hour group (P >0. 05 ). (2 )Compared with the sham operation group,the preproNPY mRNA and protein level increased significantly after reperfusion in the ischemia-reperfusion 4-hour group (P < 0. 05 ),the mRNA expressed 2. 31 ± 0. 27,and the increase of precursor protein level continued until 24 hours. Conclusion TheexpressionofprecursorPC1increasedaftercerebralischemia-reperfusioninmice, thus affecting the processing activity of PC1 ,and resulting in NPY protein,an active substrate of PC1 accumulated with the form of precursors,which may be one of the underlying mechanisms of neuronal ischemic injury.

OBJECTIVETo provide preimplantation genetic diagnosis(PGD) for two couples carrying thalassemia mutations and chromosomal abnormalities.

METHODSCouple 1 were both carriers of β 41/42 thalassemia mutations, while the husband has carried a reciprocal translocation with a karyotype of 46,XY,inv(9)(p11;q13),t(11;22)(q25;q13). Couple 2 were both carriers of α (-SEA) thalassemia mutation. Their chromosome karyotypes were both normal, but had two spontaneous abortions. The couples had received 1 and 3 blastocysts respectively through in vitro fertilization(IVF) cycles. Following the biopsy, the cells underwent whole genome amplification, and the amplified DNA from each embryo was subjected to genetic testing and a 23-chromosome single nucleotide polymorphism(SNP) microarray assay.

RESULTSThe embryo of couple 1 was diagnosed as carrier of β 41/42 thalassemia with euploid chromosomes. The embryo was transferred and resulted in intrauterine pregnancy. Similarly, an embryo of couple 2 was verified as carrier of α (-SEA) thalassemia with euploid chromosomes.

CONCLUSIONPGD for aneuploidy coupled with testing for single gene disorders via trophectoderm biopsy and whole genome amplification is feasible. The approach can attain diagnosis with minimal damage with sound clinical outcome.

BACKGROUND/AIMS: Functional dyspepsia (FD) remains a great clinical challenge since the FD subtypes, defined by Rome III classification, still have heterogeneous pathogenesis. Previous studies have shown notable differences in visceral sensation processing in the CNS in FD compared to healthy subjects (HS). However, the role of CNS in the pathogenesis of each FD subtype has not been recognized. METHODS: Twenty-eight FD patients, including 10 epigastric pain syndrome (EPS), 9 postprandial distress syndrome (PDS), and 9 mixed-type, and 10 HS, were enrolled. All subjects underwent a proximal gastric perfusion water load test and the regional brain activities during resting state and water load test were investigated by functional magnetic resonance imaging. RESULTS: For regional brain activities during the resting state and water load test, each FD subtype was significantly different from HS (P < 0.05). Focusing on EPS and PDS, the regional brain activities of EPS were stronger than PDS in the left paracentral lobule, right inferior frontal gyrus pars opercularis, postcentral gyrus, precuneus, insula, parahippocampal gyrus, caudate nucleus, and bilateral cingulate cortices at the resting state (P < 0.05), and stronger than PDS in the left inferior temporal and fusiform gyri during the water load test (P < 0.05). CONCLUSIONS: Compared to HS, FD subtypes had different regional brain activities at rest and during water load test, whereby the differences displayed distinct manifestations for each subtype. Compared to PDS, EPS presented more significant differences from HS at rest, suggesting that the abnormality of central visceral pain processing could be one of the main pathogenesis mechanisms for EPS.

OBJECTIVETo understand the distribution of diarrheagenic Escherichia (E.) coli in population in Shanghai and discuss the practice model of cooperation in enteric infectious disease prevention and control between public health institution and hospital.

METHODSSentinel hospitals were assigned, standard detection and identification of diarrheagenic E. coli were conducted, incidence curve of diarrheagenic E. coli infection was drawn and epidemiologic survey and laboratory detection were conducted for suspect diarrheagenic E. coli infection outbreaks.

RESULTSA total of 7 204 stool specimens were collected from diarrhea patients in 4 hospitals during 2012-2013, in which 712 (9.9% ) were diarrheagenic E. coli positive, including 351 enteropathogenic E. coli (EPEC) strains, 292 enterotoxigenic E. coli (ETEC) strains, 32 enteroinvasive E. coli(EIEC) strains and 6 Shiga toxin-producing E. coli (STEC/EHEC) strains, as well as 31 mixed strains. EPEC infection mainly occurred in children aged 1-5 years; and all of these infections were caused by aEPEC. The incidence peak of ETEC infection was during August, the positive rate was >20%. The ETEC infection mainly occurred in infants aged 1-28 days in 2012 and in people aged 20-60 years in 2013 (P<0.05). ST was the major type (59.6%), followed by LT (27.8%) and ST/LT (12.6%). EIEC infection increased in children obviously in 2013 (P<0.01). No EHEC O157:H7 case was detected, but two EHEC O26:H11 (eae-hlyA-stx1a) cases in children were reported for the first time in Shanghai. The survey result indicated that the multidrug-resistant ETEC (STh-CS21-CFA/I-ClyA-EatA-ST2332-SHNL0005) strain causing outbreak in 15 newborns in Shanghai in 2012 was in the same clone as the strain detected in Zigong in Sichuan province.

CONCLUSIONSignificant change has occurred in diarrheagenic E. coli distribution in Shanghai in recent years, ETEC has potential risk to cause outbreak of hospital acquired infection in neonates and food borne infection. The active surveillance on ETEC and other enteric pathogens by both public health institutions and hospitals need to be improved.
