Objective To investigate the effect of external treatment with traditional Chinese medicine on cervical spondylotic radiculopathy(CSR)and summarize nursing key points. Methods One hundred and twenty CSR patients with cervical shoulder pain and upper limb radioactive pain were randomly divided into the treatment group and control group in equal number.The treatment group were managed with external treatment with traditional Chinese medicine and the control group with conventional treatments. The curative effects were compared between the two groups 15 d after treatment. Results The treatment group achieved significantly better curative effect than the control group(P<0.05). Conclusion The external treatment with traditional Chinese medicine may effectively relieve cervical shoulder pains and radioactive pains in upper limbs induced by cervical spondylotic radiculopathy.

Objective To compare the cooling effect of ice compressing using the ice-bag packed by immobilization bag with that using the traditional way. Methods Choose 80 hyperpyretic patients who need ice compressing randomly. These ones were averagely and randomly divided into two groups: the observation group and the control group. Put the ice-bag into the self-designed immobilization bag in observation group and into the wrap as the schoolbook described in the control group, and then place it in the needed position for ice compressing. Results The nursing time was 4.50±2.40 minutes in the observation group while it was 15.52±9.54 minutes in the control group. Otherwise, the cooling effect of the observation group was obviously better than that of the control group. Conclusion Ice compressing with the ice-bag packed by immobilization bag was economical with time and effort, and it improved our nursing's efficiency with the cooling aim fulfilled.

To explore the correlation between nucleated red blood cell (NRBC) count and perinatal asphyxia in neonates.Full-term newborns born from May 2011 to November 2012 were recruited and divided into perinatal asphyxia (n =40) and normal (n =30) groups.Apgar score was recorded immediately at delivery.The umbilical arterial blood was also collected into anticoagulant-treated tube and NRBC was counted by Japan OlympusCX41 biological microscope.NRBC count for perinatal asphyxia group [(10.70 ± 2.61)/100 WBC] was significant higher than that for normal group [(2.67 ± 0.35)/100 WBC].A statistically significant negative correlation existed between NRBC and umbilical arterial blood pH,Apgar score at 1 min,BE value (r =-0.802,P ＜ 0.05 ; r =-0.639,P ＜ 0.05 ; r =-0.566,P ＜ 0.05).Associated with perinatal asphyxia in neonates,NRBC may be used as a simple index for assessing the severity of neonatal perinatal asphyxia.

To investigate the genetic character and origin of the first imported infection case of middle East respiratory syndrome coronavirus (named as MERS-CoV_China GD01), RNA was extracted from swabs of this patient followed by RT-PCR amplification. All coding gene of structural (S, E, M, E) and accessory (ORF3, ORF4a, ORF4b, ORF5, ORF8b) proteins were sequenced and analyzed. Phylogenetic analyses of structural protein coding genes of MERS-CoV_ China GD01 indicates that several substitutes exists in S coding gene and its origin belong group 5 of MERS-CoV, which were recent circulated in Saudi Arabia area, while other three structural genes (N, E, M) were very conserved. Phylogenetic analyses of accessory protein coding genes of MERS-CoV China GD01 indicates that several substitutes exists among ORF3, ORF4a, ORF4b and ORF5, while ORF8b was conserved. In conclusion, genome of MERS-CoV_ China GD01 was general conserved although several genetic variations were found among structural and accessory protein coding genes. This is the first report on sequencing and phylogenetic analyses of the first imported MERS case in China, which may pay the way for prevention and control of imported MERS-CoV infection.

Objective To establish an inactivated viral particle-based ELISA for the detection of antibodies against Middle East respiratory syndrome coronavirus (MERS-CoV) in serum samples collected from a MERS-CoV associated case. Methods Serum samples were collected from 10 newborns and 40 healthy adults. A viral particle-based ELISA was established by using the inactivated MERS-CoV virions as antigen. The levels of IgM and IgG antibodies in the serum samples were detected by the established ELISA and the cut-off values for positive detection were determined. Then the inactivated MERS-CoV virion-based ELISA was used to detect the antibodies against MERS-CoV in 5 serum samples collected from the first im-ported MERS case in China. Results The cut-off values of IgM and IgG antibodies in serum samples for ELISA were determined to be A450 readings of 0. 32 and 0. 42, respectively. The titers of IgM and IgG anti-bodies in serum samples collected at early admission to hospital from the first imported MERS case in China were both 1 ︰ 40. Seroconversion occurred 2 weeks after his admission to hospital with the titers of IgM and IgG reaching to 1 ︰ 320. Conclusion The inactivated MERS-CoV virion-based ELISA was established successfully and could be used for the detection of serum antibodies (IgG and IgM) in MERS associated cases.

OBJECTIVEThe survey will reveal current status of subclinical vitamin A deficiency (SVAD) and explore its affecting factors in children of China.

METHODSTotally 8 669 children aged under 6 years were randomly selected from 14 provinces for clinical examination, health and dietary questionnaire and serum level of vitamin A measurement with fluorescence method. The cut-off value for SVAD was defined as

RESULTSPrevalence of SVAD was 11.7% and that of suspected SVAD 39.2% in all subjects, which decreased with the increase of gross domestic product, average annual family income, mother's schooling and children's age. Prevalence of SVAD and suspected SVAD higher in rural areas (15.0%) than in urban areas (5.2%), and higher in children with a minority mother (22.6%) than in those with a Han nationality mother (8.7%). Prevalence of SVAD and suspected SVAD was higher in children whose blood samples were collected within one week in-taking vitamin A-rich food (12.6%-22.6%) than those in-taking vitamin A daily (4.1%-10.0%), and higher in children suffering from respiratory infection, fever and diarrhea two weeks before their blood collection (15.2%-20.3%) than in those without those diseases (10.1%-11.1%). Logistic regression analysis showed that poor family economic status, living in rural areas, children with a minority mother, younger age, no-dairy milk products intake, and respiratory infection and fever all were risk factors for SVAD.

CONCLUSIONSMore than half of children under six years old in China (50.9%) had vitamin A nutrition problem. Varied factors played roles to different extent in SVAD in children.
