Background and purpose:Connective tissue growth factor(CTGF) is a member of CCN family,it has been reported that CTGF involve in many biological processes and various pathological conditions.In our study,the correlation of CTGF expression and biological effects on breast cancer cell lines were investigated.Methods:The eukaryotic expression vectors containing CTGF open reading frame(ORF) pcDNA3.0/CTGF were constructed and transfected into breast cancer cell lines.The relationship between CTGF expression and breast cancer cell growth ability and proliferation,cell cycle distribution,apoptosis,cell motility and invasive capacity in vitro were observed.Results:Upregulation of CTGF expression in MCF-7 cell line could inhibit its growth ability and proliferation,increased the proportion of G0G1 phase cells,enhanced apoptosis and inhibited its invasive ability in vitro.Downregulation of CTGF expression in MDA-MB-231 cell line increased its growth ability and proliferation,decreased apoptosis and promoted its invasive ability in vitro.There were no differences of cell motility among different groups in MCF-7 and MDA-MB-231 cell lines.Conclusions:CTGF can inhibit breast cancer cell growth by increasing cell apoptosis and/or the proportion of cells in G0G1 phase.CTGF can also inhibit breast cancer cell invasive ability.

Objective Non-alcoholic fatty liver ( NAFL) is a metabolic disease and levocarnitine can be used to improve the energy metabolism of the patient .This study aimed to evaluate the clinical efficacy of levocarnitine in the treatment of NAFL . Methods We retrospectively analyzed 85 cases of NAFL treated by lifestyle intervention (control group, n=40) or by lifestyle intervention +levo-carnitine medication (medication group, n=45).In addition to lifestyle intervention, the patients in the medication group received oral levocarnitine at 10 mL tid for 4 weeks followed by a reduced dose of 10 mL bid for another 8 weeks. Results Twelve weeks after treat-ment, 37 cases (82.2%) in the medication group showed remarkable improvement and the other 8 failed to respond.In the control group, 23 cases (57.5%) were improved and 17 cases remained unimproved .There were statistically significant differences in the rate of therapeutic effectiveness between the two groups of patients (P<0.01).No adverse effects were observed during the levocarnitine medi-cation. Conclusion Lifestyle intervention +levocarnitine medication can improve NAFL .

Objective To describe the prevalence and change of rationing of nursing care (RNC) in medical and surgical units of level 2 and level 3 general hospitals across Guangdong province. Methods RNC were measured by asking nurses about the completion status of 12 necessary nursing care activities, and the prevalence of RNC in 2014 was compared with the study results from the China Hospital Nursing Workforce Research(CNWR) in 2009 (exclusively using the data of Guangdong province) to describe the change of RNC. Results Six activities were rationed averagely in 2014, and the most frequent activities rationed wereComfort/talk with patients accounted for 69.8% (975/1 396) andEducating patients and familiesaccounted for 67.3%(940/1 396). According to the CNWR in 2009, the average number of nursing care activities rationed was 3 which was statistically lower than the number in 2014 (P < 0.01). Conclusions RNC is prevalent in level 2 and level 3 general hospitals across Guangdong province, especially psychosocial care to the patients; the prevalence of RNC has not decreased since 2009.

Objective To evaluate the value of ultrasound (US) in assessment knee joint inflammation in patients with juvenile rheumatoid arthritis(JRA).Methods US scans of the knees obtained in 30 children at clinically active stage; JRA was compared with those obtained in 30 healthy children and 10 JRA patients in clinical remission.Results Changes in synovial membrane thickness and presence of fluid in suprapatellar bursa showed statistically significant differences between JRA patients with active disease and the other subjects.Alterations in contour of the articular cartilage were demonstrated in 10 knees of patients with JRA.Conclusion US is a simple sensitive and reliable methods for the assessment and monitoring of knee joint involvement in JRA.

Objective The control rate of blood pressure in hypertension patients is very low in our country , while follow-up intervention can significantly improve the situation .This study aimed to evaluate the clinical effects of anti-hypertension under follow-up intervention . Methods From October 2013 to October 2014 , 125 patients with hypertension were chose as the study objectives after first clinical anti-hypertension and were divided into intervention group (follow-up,n=65) and control group(no follow-up,n=60). Comparative analysis was made in blood pressure control , compliance with therapy and cardiovascular event incidence between the two groups after 12 weeks'intervention. Results After 12 weeks, diastolic and systolic blood pressure in intervention group was signifi-cantly lower than that in control group (P<0.05).Significant difference was also found in the compliance with drug-taking between in-tervention group and control group (73.8%vs 43.3%, P<0.01).During the follow-up period, 1 case in the control group suffered stroke and unstable angina pectoris hospitalized for treatment . Conclusion Follow-up intervention after clinical service can improve the efficacy of blood pressure control and encourage the patients to live healthy lifestyle .

Objective To establish a closed-chest pulmonary embolism-reperfusion animal model by Swan-Ganz catheter and to explore the mechanisms of pulmonary embolism(PE)-reperfusion injury(RI). Methods Experiments were made on 14 mongrel dogs,ranging in weight from 15 to 18 kg,anesthetized with 3% pentobarbital sodium.The dogs were intubated with I.D.7 endotracheal tubes.Under sterile conditions,a 7 F Swan-Ganz catheter via the external jugular vein was positioned in the unilateral pulmonary diaphragmatic lobe(DL)artery.Occlusion/reperfusion of the DL artery was controlled with 1.2 ml diluted contrast agent filled into/drawn from the balloon.After the 24 h PE,the balloon was deflated to result in 4 h reperfusion of the DL.Measurements of blood gases and tumor necrosis factor-?(TNF-?)were made at normal condition,at 24 h PE and at 4 h reperfusion.Thin-section CT scans were performed at normal condition,24 h PE,30 min,1,2,3 and 4 h reperfusion,respectively.At the end of each experiment, tissue specimens of bilateral diaphragmatic lobes were obtained for both wet/dry(W/D)weight ratio and for pathological study.Results Reperfusion pulmonary edema(RPE)was an acute,mixed,noncardiogenic edema that was observed in all 14 dogs who had been successfully established as PE/RI animal models.RPE demonstrated heterogeneous ground-glass opacifications that predominated in the areas distal to the recanalized vessels.It manifested pathologically as an edematous lung infiltrated by inflammatory cells.The mean ofPaO_2 and TNF-? of 4 h reperfusion was(81?4)mm Hg(l mm Hg=0.133 kPa)and(16.0? 2.5)pg/ml,which were significantly different(P

Objective To investigate the correlation of single nucleotide polymorphisms( SNP) of rs228648 and rs2890565 in urotensin Ⅱ (UTS2)gene with polycystic ovary syndrome(PCOS). Methods The genotypes of two SNPs in UTS2 gene were determined through polymerase chain reaction Tin-shift genotyping method. 101 Chinese Han families trios in Shandong Province consisting of fathers,mothers,and affected daughters with PCOS and 105 healthy women were recruited. The physiological and biochemical parameters including serum follicular stimulating hormone(FSH),luteinizing hormone( LH),testosterone,fasting plasma glucose,and insulin were also measured. Results The distributions of three genotypes and two alleles of SNP rs228648 in UTS2 gene were similar between PCOS group and control group. The distributions of genotypes of SNP rs2890565 in UTS2 gene differed significantly between PCOS group and control group (P<0. 05). The frequency of A allele of SNP rs2890565 in UTS2 gene was significantly higher in PCOS group than that in control group( P<0.05). Transmission disequilibrium test(TDT) did not show significantly biased transmission of two different alleles from parents to affected daughters at rs228648 locus (P>0. 05) ,but showed an excess transmission of A allele from heterozygous parents to affected offspring at rs2890565 locus (P<0. 05). The carriers with GG genotype of SNP rs228648 had significantly higher HOMA-IR compared to those with AA and AG genotypes. The carriers with AA or AG genotype of SNP rs2890565 had significantly higher fasting plasma glucose and fasting insulin compared to those with GG genotypes. HOMA-IR in cases with AA genotype was significantly higher than that with GG genotype. Conclusions There is no association of SNP rs228648 with PCOS, but exists association with insulin resistance. The genetic polymorphism of UTS2 gene rs2890565 may be associated with PCOS,and the higher frequency of A allele is likely to contribute to PCOS.

ObjectiveTo investigate the profile of Th17/Treg balance in the peripheral blood of patients with systemic lupus erythematosus (SLE).MethodsThirty-two SLE patients in active disease were selected and 30 SLE patients in remission were included in this study.The control group was consisted of 25healthy individuals.The expressions of IL-17 and FoxP3 on CD4+ T cells in the peripheral blood were assessed by flow cytometry and the mRNA levels of these two cytokines were examined by quantitative PCR respectively.ANOVA was used for statistical analysis.ResultsThe percentage of CD4+IL-17+ T cells and IL-17mRNA expression of the active group were significantly higher than those of the remission group and control group[(l.0l±0.22)％,(2.04±0.63)vs (0.48±0.16)％,(1.12±0.34) vs (0.41±0.12)％,1; P＜0.01].There was no difference between the remission group and control group(P＞0.05).However,the percentage of CI4+FoxP3 + T cells and FoxP3 mRNA expression of the active group were significantly lower than those of the remission group and control group [(2.36±t0.54)％,(0.42±0.16) vs (4.34±0.95)％,(0.87±t0.28) vs (5.09±11.17)％,1; P＜0.01 ],and there was also significant differencesbetween the remission group and control group(P＜0.05).ConclusionThl7/Treg balance shift may exist in the peripheral blood of patients with SLE and the degree of imbalance may be related to disease activity of SLE.
