Objective To explore the effects of the multidisciplinary cooperative continue nursing on the quality of life of patients with chronic obstructive pulmonary disease (COPD). Methods From December 2012 to December 2014, hospitalized COPD patients who were in the stable stage of disease and would soon be discharged and met the criteria standards were chosen. Convenient extraction of 64 patients were set as the experimental group in one ward and 50 patients as the control group in the other ward. The conventional discharge guidance was employed in the control group. While the continuation of care before discharge and 1, 3, 6 months after discharge was employed in the experimental group. The indexes such as the quality of life and 6 min walking test distance (6MWD) were observed and compared. Results The total scores and symptoms, activities, influence scores of the quality of life were 48.53±15.78, 35.38± 18.61, 57.95 ±23.69, 52.28 ±15.27 after 6 months intervention in the experimental group and 60.24 ±10.14, 52.76 ±12.36, 68.34 ±15.59, 58.55 ±11.79 in the control group, and there were significant differences (t=-5.69--2.38, P<0.05). 6MWD was (267.46 ±64.64) m after 6 months intervention in the experimental group,which was more than that before intervention (169.42±48.46) m, and there was significant difference (t=-9.71, P<0.01). 6MWD was (201.32±53.93) m after 6 months intervention in the control group, which was not significantly better than that in the experimental group (t=5.82, P<0.01). Conclusions The quality of life of patients with COPD can be significantly improved by the multidisciplinary cooperative continue nursing education after discharge.

Objective To expore the mechanism of low-dose interfone-γ(IFN-γ) influences on differentiation of oligodendrocyte precursor cell. Methods The cerebral cortex samples were obtained from one day old SD rats to form mixed single cell suspensions. After culturing in full medium for 7 to 10 days, succession and differential velocity adherent technique were performed to acquire oligodendrocyte precursor cell and cultured in serum-free medium. IFN-γ, AG490 and Fludarabine were added during the culture of oligodendrocyte precursor cell and reverse transcription-polymerase chain reaction, Western blot and flow cytometry were performed to evaluate the expression of intracellular P27kip1 and its influence on the differentiation of oligodendrocyte precursor cell. Results (1)The expression of P27kip1 mRNA and protein was lower in IFN-γ group than in control group (t=85. 535, P<0. 05;t= 12. 481, P<0. 05), while the expression of P27kip1 mRNA and protein in IFN-γ+AG490 group and IFN-γ+Fludarabine group were both higher than those in IFN-γ group (P<0. 05). (2) The phosphorylation levels of JAK2/STAT1 in INF-γ group were higher than that in the other three groups (P<0. 05). (3) The percentage of myelin basic protein positive cells was (68. 42 ± 2. 53)% in IFN-γ group, lower than that in control group [(88.21 ± 1.97)%](t=10.682, P < 0.05). Myelin basic protein positive cells in IFN-γ + AG490 group were (57. 63 ±2. 75) %, lower than those in the IFN-γ group. The same figure in IFN-γ+Fludarabine group were (79. 53±4. 15)% , higher than those in IFN-γ group (t = 3.957, P<0.05). Conclusions Low-dose IFN-γ can regulate the expression of intracellular P27kip1 through JAK2/STAT1 signal transduction pathway and Fludarabine may participate in this process and improve the differentiation and maturation of oligodendrocyte precursor cell.

Objective To investigate the protective effects and mechanisms of NF-KB inhibitor pyrrolidine dithiocarbamate (PDTC) on infant rabbits with lung injury caused by mechanical ventilation. Methods Twenty healthy infant rabbits were randomly divided into four groups. (1) Mechanical ventilation (MV, with VT = 24 ml/kg);(2) Mechanical ventilation plus PDTC pre-treatment (MVP, VT = 24 ml/kg with PDTC 100 mg/kg injection via ear vein half an hour prior to MV) ; (3) Mechanical ventilation combined with endotoxin (EMV, 0.1 ml/kg of endotoxin dripping into trachea then on MV, VT = 24 ml/kg) ; (4) EMV plus PDTC pretreatment (EMVP, PDTC 100 mg/kg injection via ear vein followed by 0.1 mg/kg of endotoxin dripping into trachea in half an hour then on MV with VT = 24 ml/kg for 4 h continuously. MPO and the activation of NF-κB in lung tissues and the genetic expression and protein quantity of TNF-α and IL-8 in homogenate were measured. The pathological changes in lung tissues were examined. Results Pre-treatment with PDTC had significant minor pathological changes caused by MV and MV plus endotoxin, which were indicated by the fact that MPO, activation of NF-KB and the genetic expression and protein quantity of TNF-α and IL-8 were significantly suppressed. Conclusions PDTC could decrease the expression, synthesis and release of pro-inflammatory cytokines. This may be through suppressing the activation of NF-κB resulting in less infiltration with inflammatory cells and protective effects on lung injury caused by MV and MV plus endotoxin.

Background:Faecalibacterium prausnitzii( Fp) is one of the most abundant bacterium in human intestinal microbiota,and is closely correlated with the process of colitis-associated colorectal cancer(CAC). Aims:To observe the effect of Fp on CAC,and investigate the possible mechanism. Methods:The model of CAC was induced by azoxymethane (AOM)and dextran sodium sulfate( DSS). Fifty-two C57BL/ 6J mice were randomly divided into 4 groups:group A (AOM + DSS),group B(AOM + DSS + Fp),group C(AOM + DSS + Fp supernatant)and group D(control group). All the mice were sacrificed on day 92. DAI was assessed,serum levels of TNF-α and IL-10 were determined by ELISA. HE staining was used to examine the grade of tumor. Expressions of VEGF,COX-2,NF-κB in tumor tissue were measured by immunohistochemistry. Results:The tumorigenesis rates of group A,B,C were 100% ,100% and 77. 8% ,respectively;mainly were high-grade intraepithelial neoplasia. The tumor load in group A was significantly higher than that in group B (P < 0. 01),and the spleen index in group B was significantly higher than that in group C(P < 0. 01). Serum level of TNF-α was significantly lower(P < 0. 05)and IL-10 was significantly higher(P < 0. 05)in group A than that in group B. No significant differences in expressions of VEGF,COX-2,NF-κB were found among group A,B and C. Conclusions:Fp had no obvious effect on the occurrence rate of CAC,and Fp supernatant could decrease the incidence of CAC in mice. Fp and its supernatant could reduce the tumor load via regulating the expressions of TNF-α,IL-10.

Objective To detect the development of fetal nasal bone with ultrasound scan in the second and third trimester, and to evaluate the value of fetal nasal bone hypoplasia in diagnosing fetal chromosomal abnormalities. Methods Prenatal ultrasound examination was performed in 1415 normal fetuses. The nasal bone length (NBL) and the nasal bone angle (NBA) were measured on the mid-sagittal plane. The karyotype of the cases with nasal bone abnormality was analyzed. Results The fetal nasal bone was successfully detected with two-dimensional ultrasonography in 95% of the subjects. The NBL increased with the gestational age while the NBA kept unchanged with the average value of 54. 4?(44. 4?-69. 2?). Forty-two cases with nasal bone hypoplasia were diagnosed prenatally including nasal bone defect (20 cases), small NBA (15 cases), short nasal bone (4 cases) and short nasal bone with small NBA (3 cases). Cordocentesis was performed in 21 cases among which 12 with abnormal karyotype, including 3 cases of trisomy 21, 3 cases of trisomy 13, 4 cases of trisomy 18 and 3 other chromosomal abnormalities. Conclusions Fetal nasal bone hypoplasia was closely related to the chromosomal abnormalities. The evaluation of fetal nasal bone with prenatal sonography is an important criteria for screening fetal chromosome abnormalities during the mid-trimester.

OBJECTIVETo compare the effects between plum-blossom needle tapping at Jiaji (EX-B 2) combined with rehabilitation and simple rehabilitation for ataxia of cerebellar apoplexy.

METHODSSixty patients with ataxia of cerebellar apoplexy were randomly divided into an observation group,and a control group,30 cases in each one. Conventional rehabilitation training was applied in the control group. While based on the treatment as that of the control group, plum-blossom needle tapping at Jiaji (EX-B 2) was used in the observation group. All the treatment was given for 4 weeks. International cooperative ataxia rating scale (ICARS), Berg balance scale (BBS) and Barthel index (BD were observed before treatment,after 2-week treatment and 4-week treatment. Also, clinical effects After treating for 2 weeks and for 4 weeks, the results of ICARS,BBS and BI were obvi were compared.

RESULTSAfter treating for 2 weeksand for 4 weeks, the results of ICARS, BBS and BI were obviously better than those before treatment in the two groups (all P<0.05). After 2-week treatment,there was no sta tistical significance between the two groups (all P>0. 05). After 4-week treatment,all the scores of the observation group were apparently superior to those of the control group (all P<0. 05). The total effective rate was 96. 7% (29/30) in the observation group, better than 80. 0% (24/30) in the control group after 4-week treatment (P<0. 05). CCONCLUSION:Plum-blossom needle tapping at Jiaji(EX-B 2) combined with rehabilitation training markedly improve the coordination and balance functions and activities of daily life, which are better than simple rehabilitation.

Objective To investigate the clinic value of ultrasonographic fetal nasal bone examination as a screening marker for Down syndrome(DS).Methods The study was conducted in the First Affiliated Hospital of Sun Yat-sen University from Oct 2004 to Mar 2007.Two-dimensional ultrasound was used to assess the fetal nasal bone of 1863 normal pregnancies(normal group)and 25 cases with DS fetus (study group)during their second and third trimesters.The incidence of nasal bone absence or short nasal bone in two groups was determined.The fetal nasal bone absence should be confirmed in three orthogonal planes of the fetal face.and the short nasal bone included the cases that the fetal nasal bone was shorter than the 2.5th percentile of normal according to the gestational week.The diagnostic test index was used for assessing the value of fetal nasal bone abnormality as a marker in prenatal screening for DS.Results (1)1761 fetuses of normal group were successfully examined for the nasal bone and the detection rate was 94.5%(1761/1863).102 fetuses failed examination because of inconvenient intra-uterine position.(2)The nasal bone length grew in a linear fashion throughout pregnancy and the growth pattern correlated well with gestational age(r=0.605,P＜0.05)in normal group.The nasal bone was absent in 3 normal fetuses (0.2%,3/1761)and short nasal bone was found in 44 normal fetuses(2.5%,44/1761).(3)The nasal bone was absent in 7 DS fetuses(28.0%.7/25)and short nasal bone was found in 15 DS fetuses (60.0%.15/25).(4)When the absence of nasal bone was used as a cut-off,the sensitivity for DS was 28.0%.the specificity was 99.8%,the positive likelihood ratio was 164.45(95%CI:45.11-599.60),and the negative likelihood ratio was 0.72(95%CI:0.57-O.92).When short nasal bone was used as a cut-off.the sensitivity was 60.O%,specificity was 97.5%.the positive likelihood ratio was 24.03(95%CI:7.15-80.71),and the negative likelihood ratio was 0.41(95%CI:0.29-0.59).Conclusion Fetal nasal bone hypoplasia at the second and third trimester scan is associated with a high risk for Down syndrome and it can be used as a screen marker for this chromosomal abnormality.

Objective To analyze the concomitant malforrnations,chromosomal abnormalities and outcomes in prenatally diagnosed congenital diaphragmatic hernia (CDH) cases. Methods Cases of fetal CDH,prenatally identified in the First Affiliated Hospital of Sun Yat-sen University from January 2002 to November 2008,were recruited.The concomitant realformations,chromosomal abnormalities and outcomes of fetal CDlH were analyzed.Fisher's exact test was applied. Results During the study period,71 CDH cases were identified including 62(87.3%) left-sided CDH and 9 (12.7%) right-sided ones.Among the 71 CDH fetuses,38(53.5%)were isolated CDH.33 (46.5%)were complicated with other realformations(complex CDH),including 18(54.5 0A) cardiovascular defects,10 (30.3%)central nervous system abnormalities,9(27.2 0A)genitourinary abnormalities and others.Fetal karyotying was performed in 19 out of the 71 CDH fetuses.among which 12 were isolated CDH cases with normal karyotype,and 4 of the rest 7(4/7)complex CDH cases with chromosomal abnormalities showing a significant differenee compared to the isolated CDH (P.0.009).Sixty-five pregnancies were terminated including all complex CDH(n=33)and 32 isolated CDH.The rest 6 isolated CDH fetuses were term delivered and 5 of them survived after repair of diaphragmatic hernia and one died after birth. Conclusions Left-sided CDH are more common than right-sided ones. Approximately half of the CDH cases are complicated with other malformations,especially cardiovascular abnormalities.The risk of chromosomal abnormalities increases in complex CDH and is relatively low in isolated CDH.The influence of surgical procedure on the prognosis of CDH has not yet determined.
