Objective To investigate the effects of Propofol in blood spinal cord barrier (BSCB) disruption induced by spinal cord ischemia reperfusion injury (SCIRI). Methods 72 Japanese white rabbits were randomly assigned into 3 groups: sham-operation group (S); ischemia/reperfusion group (I/R) and Propofol treatment group (I/R + P). The Group S was separated the aorta without cross-clamping. SCIRI was induced in rabbits by infrarenal aortic occlusion for 30 minutes. Propofol was intravenously infused at 10 minutes before aortic clamping and at onset of reperfusion in the Group I/R + P. The Group S and Group I/R were intravenously infused 0.9%sodium chloride. Hind-limb motor function was assessed using Tarlov criteria, and histological observation by histological examination. The permeability of the BSCB was examined using EB as vascular tracers. The expression of MMP-9, claudin-5 and NF-κB were assessed by Western blot, RT-PCR. Results Propofol minimized the neuromotor dysfunction and histopathological deficits and attenuated EB extravasation. In addition, Propofol suppressed SCIRI-induced increase of MMP-9 and NF-κB. Finally, Propofol reduced the loss of claudin-5. Conclusion Propofol stabilizes the BSCB integrity after SCIRI. This beneficial effect is partly mediated by inhibition of MMP-9 and preservation claudin-5 and relates to inhibiting the NF-κB signal pathway.

Objective To investigate the acoustic characteristics of the voice of 3~6 years old children with hearing-impairment. Methods The voice samples were collected from 148 hearing-impaired children and 122 normal children, all aged 3~6 years. The acoustic parameters including F0, F0SD, jitter, shimmer, NNE, OQ, SQ, AQ, STF were compared. Results The F0, SQ, STF, F0SD, jitter were more in the children with hearing-impairment than in the normal children (P<0.05). There was no significant difference between hearing-impairment and normal children in shimmer, NNE, OQ and AQ (P>0.05). There was no significant difference of all the acoustic parameters among children with different ages (P>0.05), except the NNE was less in 3~4 years old children than 5~6 years old children (P<0.05). There was no significant difference of all the acoustic parameters between boys and girls (P>0.05). Conclusion The vibration of vocal cords is instable and irregular,saying overquick and close intensely in hearing-impaired children. The age and sex do not influence the acoustic parameters, except NNE is less in younger children.

Objective To explore the speech respiratory characteristics of 7-15 years old children with spastic cerebral palsy and the differences between ordinary children and children with cerebral palsy.Methods The maximum phonation time (MPT) and maximum counting ability (MCA) of 90 ordinary children and 58 children with cerebral palsy aged 7-15 years were measured and a comparison between the 2 groups were conducted.Results (1) Age has significant effects on MPT and MCA of the ordinary children (P ＜0.05).The MPT and MCA of the ordinary children at the age of 7 ～9 years and 10 ～ 12 years are lower than the ones at the age of 13 ～ 15 years.Age has almost no effects on MPT and MCA of children with cerebral palsy(P ＞0.05) ; (2)Sex has no significant effects on MPT and MCA of ordinary children and children with cerebral palsy (P ＞0.05) ; (3) The MPT and MCA of children with cerebral palsy are significantly lower than those of ordinary children (P ＜0.05).Conclusions The MPT and MCA of ordinary children are increased with the growth of age,especially after the age of 13 years,but the children with spastic cerebral palsy do not show that kind of trend and demonstrate a state of retardation of speech respiratory function.Compared with ordinary children,the children with spastic cerebral palsy are easier to suffer from insufficient respiratory support and poor respiratory-phonatory coordination.

Objective To investigate the expression of CEA, NSE and CYFRA21-1 in lung cancer, and the significance of combined determination of three tumor markers in the detection of lung cancer. Methods CEA, NSE and CYFRA21-1 levels in serum of 65 patients with lung cancer, 50 patients with benign lung diseases and 38 normal adults were measured by enzyme linked immunosorbent assay (ELISA). The association of CYFRA21-1, NSE, and CEA level with the type of lung cancer in pathology were also studied. Results In comparison, the serum levels of CEA, CYFRA21-1 were increased more obviously in patients with lung cancer than that of patients with benign lung diseases and the normal adults (P<0.01). The levels of serum and the sensitivity of CEA, NSE and CYFRA21-1 were related to pathology type. The sensitivity and specificity increased by combined measurement of CEA, NSE, and CYFRA21-1. Conclusion These findings suggest that the serum CEA, NSE and CYFRA21-1 levels is increased in patients with lung cancer, and the increasing extents is not same in lung cancer with different pathology types. CEA, NSE and CYFRA21-1 are significant in adjuvant diagnosis of lung cancer.

Objective:To explore the research progress and hotspots of nurse-led care models in China, in order to provide references for further research.Methods:The Papers related to nurse-led care models included before 2019 were retrieved from Wanfang database and based on core nursing periodicals from Chinese S&T Journal Citation Reports(Natural Science)(2018 edition), used Bicomb2.0 for word frequency analysis of key words, then used SPSS22.0 for clustering analysis.Results:Totally 118 references and 33 high frequency keywords were retrieved. The number of literature about nurse-led showed a fluctuating upward trend. Researchers could get most of the information about nurse-led intervention mode from Journal of Nursing Science, Chinese Nursing Research and Chinese Nursing Management. By cluster analysis, the hotspots of nurse-led mainly involved critical illness, tumor, chronic disease, community rehabilitation and so on. Conclusions:The nurse-led model has been used in many kinds of diseases and has formed a certain scale, but there is still more room for development. Nursing experts from different regions should strengthen cooperation to improve the nurse-led intervention mode.

OBJECTIVETo evaluate the prognosis of cervical intraepithelial neoplasia grade 1 (CIN1) at different follow-up time points in Chinese women and the relationship with high-risk human papillomavirus (HR-HPV) infection.

METHODSBiopsy-confirmed CIN1 women were followed up from cervical cancer screening cohorts established during 1999 to 2008 in Xiangyuan county, Yangcheng county, Qinxian county and Wuxiang county, Shanxi Province.In each follow-up visit, participants were examined by visual inspection with acetic acid, liquid-based cytology and HR-HPV DNA testing. Those with any positive results received colposcope and biopsies. The cumulative incidence rates of CIN grade 2 or worse (CIN2+) and CIN grade 3 or worse (CIN3+), regression rates and persistent rates were calculated using pathological findings as a gold standard. The risks of progression related with HR-HPV were evaluated stratified by baseline and follow-up HR-HPV status.

RESULTSA total of 228, 224, 261 and 105 CIN1 women received the 1-year, 2-year, 6-year and 11-year follow-up exams, respectively. The cumulative incidence rate of CIN2+ among baseline HR-HPV positive women was 4.8% (6/126), 10.7% (16/150), 16.9% (29/172) and 35% (19/55) in the above follow-up visits, respectively, and their risk of progression was 2.7(95%CI:0.3-22.0), 2.9 (95%CI:0.7-12.1), 12.0 (95%CI:1.7-86.2) and 30.6 (95%CI:1.9-493.5) times higher than baseline HR-HPV negative women. Moreover, the cumulative incidence of CIN2+ among women with positive HR-HPV both at baseline and follow-up visit was 11% (6/55), 14% (6/42), 17% (10/60) and 50% (13/26) in the above follow-up visits, respectively.No new CIN2+ cases were found among those with negative HR-HPV both at baseline and follow-up visits.

CONCLUSIONGiven that CIN1 progression is related to HR-HPV infection, different follow-up intervals and strategies for CIN1 should be taken according to HR-HPV infection status.

OBJECTIVETo explore the relation between genetic polymorphisms of NQO1, GSTT1 and risks of chronic benzene poisoning (BP).

METHODSA case-control study was conducted. 152 BP patients and 152 workers occupationally exposed to benzene without poisoning manifestations were investigated. Polymerase chain reaction (PCR), denaturing high-performance liquid chromatography(DHPLC) and sequencing were used to detect the single nucleotide polymorphisms(SNPs) of the promoter and complete coding-region of NQO1 gene. Multiple PCR was used to detect GSTT1 genotype.

RESULTSIn smoking population, there was 7.73-fold (95% CI: 1.71-34.97, P = 0.010) of risk in BP subjects carrying NQO1c. 609 T/T genotype, compared with those carrying C/C and C/T. genotype. In drinking population, the individuals carrying the 6th extron of NQO1c. 609 T/T homozygote genotype had a 11.00-fold(95% CI: 1.89-63.83, P = 0.005) risk of BP compared to those with NQO1c. 609 C/T and C/C genotypes.

CONCLUSIONThe subjects carrying NQO1c. 609 T/T genotype and together with the habit of smoking or drinking may be more susceptible to BP.
