Objective The nursing staff's output and journals distribution of core scientific journals papers were analyzed, providing evaluation data and a decisive basis for scientific research management. Methods A retrospective analysis was performed to the publication of core journals papers of nursing staff in 2013-2015 based on the publication from different nursing positions , the ranking of published nursing papers from different departments and different journals by using analysis method of bibliometric. Results About 1550 nursing papers were published , of which the number of authors whose paper was published in core journals was 216 , the number of papers published in core journals was 378, and 38 authors published more than 3 papers (17.6%). The core journals papers published rate in different position was statistically significant (P<0.01). The papers published journals were concentrated in nursing class. Dominated the first 3 places in the list of core journals paper number of departments were department of nursing , cancer center and operation room, respectively. Conclusion In order to improve the nursing scientific research level of nursing staff, it is necessary to establish a theoretical system of scientific knowledge training , formulate a long-term effective mechanism in paper management , focus on scientific research talent introduction and training and mobilize the nursing research enthusiasm of nursing staff.

Objective To explore pathogenic composition of hand,foot and mouth disease(HFMD),and the molecular typing of enterovirus in Tianjin Children′s Hospital in 2016.Methods Single center study.A total of 327 samples of HFMD cases which collected from Tianjin Children′s Hospital from March to November in 2016 were tested for nucleotide acid of enterovirus(EV),human enterovirus 71(EV71),Coxsackievirus A 16(CA16)by real-time reverse transcription polymerase chain reaction(RT-PCR),among which 104 sample of other EV positive were selected to amplify and sequence the whole VP1 region by using RT-PCR.Homology was analyzed and phylogenetic tree were constructed by comparison of the sequence with all subgenotype of EV by Chromas1.62 and MEGA6.06.EV positive rate in different age groups were compared by SPSS20.0.Results Of all the 327 HFMD cases tested,there were 272 EV positive cases,the constituent ratio of EV71,CA16 and other EV were 55.1％(150/272),6.6％(18/272)and 38.2％(104/272)respectively.The EV positive rates of different age groups(69.0％-90.9％)were different significantly(x2=15.897,P=0.044),the 3 years-old-group had the highest EV positive rate than that of the other age groups(90.9％,40/44).Of all 104 samples of other EV tested,34 were CA10(12.5％)and 14 were CA6(5.1％).Phylogenetic analysis of 11 EV71 VP1 and 20 CA10 VP1 showed that the EV71 and CA10 strains belonged to genotype C4a and genotype G,respectively.ConclusionsEV71 was still the predominant pathogen in spite of the constituent ratio of other EVs increased markedly in 2016 in Tianjin.It is important to enhance etiological monitoring for control and prevention of HFMD.

To observe a PPAR-alpha agonist effect of N-oleoylethanolamine (OEA) on CB2 (cannabinoid receptor 2), an anti-inflammatory receptor in vascular endothelial cell, healthy HUVECs and TNF-alpha induced HUVECs were used to establish a human vascular endothelial cell inflammatory model. Different doses of OEA (10, 50 and 100 micromol x L(-1)) had been given to HUVECs, cultured at 37 degrees C for 7 h and then collected the total protein and total mRNA. CB2 protein expression was detected by Western blotting and CB2 mRNA expression was assayed by real-time PCR. As the results shown, OEA (10 and 50 micromol x L(-1)) could induce the CB2 protein and mRNA expression, but not 100 micromol x L(-1). To detect if anti-inflammation effect of OEA is partly through CB2, CB2 inhibitor AM630 was used to inhibit HUVEC CB2 expression, then the VCAM-1 expression induced by TNF-alpha was detected, or THP-1 adhere to TNF-alpha induced HUVECs was examined. OEA (50 micromol x L(-1)) could inhibit TNF-alpha induced VCAM-1 expression and THP-1 adhere to HUVECs, these effects could be partly inhibited by a CB2 inhibitor AM630. The anti-inflammation effect of OEA is induced by PPAR-alpha and CB2, suggesting that CB2 signaling could be a target for anti-atherosclerosis, OEA have wide effect in anti-inflammation, it may have better therapeutic potential in anti-inflammation in HUVECs, thus achieving anti-atherosclerosis effect.

Objective:To explore the cytogenetic characteristics of hypospadias in children by karyotype analysis.Methods:From June 2008 to May 2018, 45 children with hypospadias in Tianjin Children's Hospital had cytogenetic abnormalities. Their median age was 10 months(range 3 hours to 5 years old). Of the 45 cases, 20 were proximal hypospadias, 1 was middle hypospadias. All 24 cases had varying degrees of genitourinary malformations. Among them, 15 cases had unilateral or bilateral cryptorchidism, 5 cases had scrotal division, 3 cases had penile scrotal transposition, 3 cases had small penis, 3 cases had indirect inguinal hernia, 1 case had repeated urethra, 1 case had hydrocele and 1 case had concealed penis. To the other systemic malformations, there was 1 with cleft lip and palate and 1 with congenital heart disease. G-banding karyotype analysis of peripheral blood lymphocytes was performed in all 45 cases.Results:Among the 45 cases of hypospadias with abnormal karyotypes, with an abnormal rate of 14.0%, 28 cases (62.22%) had sex chromosome abnormalities, including (47, XXY), (46, XX/47, XXY), (45, X0/47, XYY), etc. Sexual inversion occurred in 8 cases (17.78%), all of which were 46, XX. There were 4 autosomal abnormalities (8.89%), including (46, XY, 9p+ ), (46, XY, 10p+ ) and (46, XY, 1q+ ). Chromosome polymorphism was found in 4 cases (8.89%), including [46, XY, inv(9)] and [46, XY, 16qh+ ], and the equilibrium translocation of 1 case (2.22%) was [45, XY, -21, -22, + t(21; 22)]. Among the 45 cases, 8 sex reversal children with (46, XX) chromosome karyotype were all proximal hypospadias.Conclusions:Children with hypospadias may be associated with chromosomal karyotype abnormalities, including sex chromosomal abnormalities, autosomal abnormalities, chromosome polymorphism and balanced translocation. Among them, sex chromosome abnormality was the most common and balanced translocation was the least.

OBJECTIVETo explore the relation of the anogenital distance (AGD) with cryptorchidism in male newborns.

METHODSThis study included 350 male infants delivered in two community hospitals between September 2013 and September 2014. Within 24 hours after birth, a pediatric surgeon measured the AGD of the neonates and determined whether they had cryptorchidism. According to the testicular position, we divided the undescended testes into three types: upper scrotal, inguinal, and non-palpable.

RESULTSTotally 39 cases of cryptorchidism were found in the 350 newborns. The AGD of the cryptorchidism infants was significantly shorter than that of the normal neonates ([2.01 ± 0.22] vs [2.35 ± 0.19] cm, P < 0.01), and statistically significant differences remained even when preterm and low birth-weight infants were excluded ([2.32 ± 0.14] vs [2.06 ± 0.19] cm; (2.37 ± 0.17) cm vs (2.12 ± 0.12) cm, all P < 0.01). The newborns with higher-position cryptorchidism had a shorter AGD, though with no significant difference (F = 0.434, P > 0.05). No significant differences were observed in the AGD between unilateral and bilateral cryptorchidism ([1.96 ± 0.13] vs [2.02 ± 0.17] cm, P > 0.05).

CONCLUSIONShorter AGD is associated with a higher incidence of cryptorchidism in male newborns. AGD could serve as a potential biomarker for disruption of androgen action during the male programming window period.

In 2013, the World Health Organization reported the first case of human infection with a new influenza A (H7N9) virus in China. This has caused damage and panic within certain areas in China. Therefore, analysis of this virus with bioinformatics technology is very necessary. Neuraminidase (NA) is one of the most important antigens of the influenza virus and an important target for anti-flu drugs. In this study, the nucleotide and protein sequences of NA gene of A/H7N9 influenza viruses were retrieved from the NCBI database, and MEGA 5.0 software was employed to construct a phylogenetic tree based on the nucleotide coding sequence; BioEdit software was used to align the nucleotide and protein sequences of NA and calculate the homologies of nucleotides and amino acids and then to analyze the important mutation sites of NA gene. The results demonstrated that the spread of influenza virus H7N9 showed certain geographical and temporal relations. The H7N9 virus isolated from China in 2013 belonged to Euroasiatic serotype, and its NA stalk region hadobvious variation, which may be one of the reasons that this virus infects human. These analyses may be very helpful for understanding the evolutionary relationship and mutation trend of A/H7N9 influenza viruses.
