Objective To investigate the relationship between the expression of CC chemokine ligand 5(CCL5)and S100 calcium binding protein A4 (S100A4)protein in breast cancer tissues with clinicopathological features and prognosis.Methods The expression of CCL5 and S100A4 in 40 cases of normal breast tissues and 120 cases of breast cancer were detected by immunohistochemistry,and the relationship between the degree of expres-sion and the clinicopathological features and prognosis of breast cancer was analyzed.Results The expression posi-tive rates of CCL5 and S100A4 in breast cancer tissues were 56.67% and 62.50% respectively,which were not expressed in normal breast tissues,and the differences were statistically significant (χ2CCL5 =39.403,P <0.01;χ2S100A4 =47.062,P <0.01).The expression of CCL5 in breast cancer tissues was statistically correlated with clinical staging(χ2 =10.141,P <0.01 ),pathological type (χ2 =5.769,P =0.017)and lymph node metastasis (χ2 =34.178,P <0.01),but not correlated with patients'age,tumor size,pathological grading(all P >0.05 ).And the expression of S100A4 was statistically correlated with clinical staging(χ2 =44.311,P <0.01)and lymph node metas-tasis(χ2 =14.843,P <0.01 ),but not correlated with patients'age,tumor size,pathological type and pathological grading(all P >0.05).The expression of CCL5 and S100A4 in breast cancer was positively correlated(r =0.301, P <0.01).CCL5 was positively correlated with the recurrence of breast cancer(OR =6.270,P <0.01),and S100A4 was not correlated with the recurrence of breast cancer(OR =1.103,P =0.768).Survival analysis showed that the disease -free survival time of patients with positive CCL5 expression was significantly shorter than the patients with negative CCL5 expression(χ2 =11.851,P <0.01 ),and the disease -free survival time of patients with positive S100A4 expression was significantly shorter than the patients with negative S100A4 expression(χ2 =5.433,P =0.021).The joint detection showed that the disease -free survival time in CCL5(+)+S100A4(+)group was sig-nificantly lower than that of CCL5(+)or S100A4(+)group(χ2 =15.341,P <0.01)and CCL5 (-)+S100A4 (-)group(χ2 =15.341,P <0.01).Conclusion The expression of CCL5 and S100A4 in breast cancer can reflect the metastasis and staging of breast cancer,which can be used to judge the clinical pathological characteristics and prognosis of breast cancer.

Abstract: Molecular genetic map is a fundamental organizational tool for genomic research. However, a genetic linkage map for Bupleurum chinense DC. has not been developed. In this study, with the theory of pseudo-testcross, 96 F1 plants from an intraspecific cross of B. chinense were used as mapping populations. Twenty eight ISSR (inter-simple sequence repeat) primers and 44 SSR (simple sequence repeat) primers were used to detect the polymorphisms between the parental plants, and of them, 28 ISSRs and 14 SSRs were selected to analyze the F1 populations. The map consisted of 13 linkage groups which included 80 (72 ISSRs and 8 SSRs) loci, and covered 2 633.9 cM with an average density of 33.4 cM. All 13 linkage groups consisted of 2-31 loci ranging in length from 15.4-1295.7 cM. This map will provide a basis for studies on gene mapping, map-based cloning and maker-assisted selection of important traits in B. chinense.

Objective To study the influence of early intensive blood pressure (BP) lowering treatment on peri-he?matomal secondary neuronal injury and prognosis after acute intracerebral hemorrhage. Methods A randomised con?trolled trial consisting of 36 consecutive patients within 6 h of intracerebral hemorrhage onset were randomly assigned to intensive BP lowering group and guideline BP lowering group. All patients underwent MR spectroscopy at 72 h and were followed up 90 days. N Acetyl Aspartate/Creatine (NAA/Cr) and lactic acid wave around peri-hematomal at 72 h, neuro?logic function at early stage, and death and/or disability at 90d were compared between these two group. Results Spec?trum lines were obtained from thirty-one patients:14 from intensive BP lowing group and 17 from guideline BP lowering group. There was no significant difference in the percentage declines of NAA/Cr at 72 h between the two groups (13.3%± 4.2% vs. 11.9%± 2.8%, P = 0.308). There was no statistical differences either in neurologic function at 7 d or in death and/or disability at 90 d (P>0.05). Conclusions Early intensive BP-lowering treatment had no role on peri-hematomal secondary neuronal injury and prognosis after acute intracerebral hemorrhage. Further high-quality and large-scale ran?domised controlled trial are necessary to verify this result.

Objective To observe the incidence and clinical feature of sleep-related breathing disorder in patients with idiopathic pulmonary fibrosis (IPF). Methods Thirty-four IPF patients who were measured by polysomnography (PSG) were collected in the Department of Respiration of Tianjin Medical University General Hospital. According to the results of apnea hypoventilation index (AHI), patients were divided into pure IPF group (AHI<5 events/h, n=7) and IPF combined with obstructive sleep apnea hypopnea syndrome (IPF+OSAHS) group (AHI≥5 events/h, n=27). The PSG reports of two groups were analyzed, and the correlation between AHI and pulmonary function and oxygen saturation in sleep and at wake were analyzed. Results (1)Thirty-four IPF patients were all demonstrated sleep disorders, low sleep efficiency, increased proportion of stageⅠand stageⅡand decreased proportion of stageⅢand rapid eye movement (REM). The arousal index and the proportion of stageⅠand stageⅡwere higher in IPF+OSAHS group than those of pure IPF group (P<0.01), while the proportion of stageⅢwas lower in IPF+OSAHS group than that of pure IPF group (P<0.01). There was no significant difference in stage REM between two groups. (2)Twenty-seven patients (79%) combined with OSAHS, among which five subjects (15%) were mild OSAHS with 5 events/h≤AHI<15 events/h, and 22 subjects (65%) were moderate-severe with AHI≥15 events/h. The main type of sleep-disorder breathing was hypoventilation, which mainly happened in stage REM. (3) Thirty-four IPF patients showed sleep hypoxemia, and the oxygen desaturation index (ODI) was higher in IPF-OSAHS group than those of pure IPF group (P<0.05). (4)The AHI was positively correlated with body mass index (r=0.791, P<0.05), and was negatively correlated with forced vital capacity (FVC%pred) (r=-0.574, P<0.05) and forced expiratory volume in 1 second (FEV1%pred) in IPF patients (r=-0.664, P<0.05). The lowest oxygen saturation (LSO2) and mean oxygen saturation (MSO2) in sleep were positively related with oxygen saturation at wake (r=0.421 and r=0.464, P<0.05 respectively). Conclusion The IPF patients show severe sleep disorder and hypoxemia, which can be worsen by OSAHS and produce negative effect on daily life. We should initiate active treatment in patients with sleep-related breathing disorders.

Aim To explore the effects of chrysin on endothelial dysfunction induced by acute high glucose.Methods ① The effects of chrysin on normal isolated aortic at contraction induced by PE and on endothelial dysfunction induced by high glucose were tested in the following medium: normal group,chrysin group;normal-glucose group: glucose 11mmol·L-1 in Krebs' solution;high-glucose group: glucose 44 mmol·L-1 in Krebs' solution;mannitol group: mannitol 33 mmol·L-1 in Krebs' solution and chrysin group: 44 mmol·L-1 Glu+chrysin 1.0 μmol·L-1 in Krebs' solution.② The effects of chrysin on HUVEC cell viability after incubated in high glucose were observed in the following groups: normal-glucose group: glucose 5.5 mmol·L-1 in culture solution;high-glucose group: glucose 33.3 mmol·L-1 in culture solution;mannitol group: mannitol 27.8 mmol·L-1 in culture solution and chrysin group: chrysin(25,50 μmol·L-1)in culture solution.And the NO release was also testd in these groups.Results ① Chrysin could induce vaso-dilation in a dose-dependent manner at normal glucose.The Emax was(58.94±9.61)％,and the EC50 value was 51.9 μmol·L-1.After incubating the aortic rings with high glucose(44 mmol·L-1)for 4 h,there were significant differences in ACh-induced vascular relaxation between the normal glucose group and the high glucose group.The Emax was(32.12±3.92)％and the EC50 value was 78.0 μmol·L-1 of high glucose group(P<0.01).The endothelium-independent relaxation induced by SNP was not significantly different between the two groups.And chrysin(1.0 μmol·L-1)could reverse the decline of ACh-induced vasorelaxation response induced by high glucose(44 mmol·L-1).The Emax was(70.7±3.87)％and the EC50 value was 0.852 μmol·L-1.② The cell viability of HUVEC was depressed after incubated in high glucose,and chrysin could reverse the decline in a concentration-dependent way.And chrysin in defferent concentrations could increase the cell NO release.Conclusion Chrysin could prevent the acute high glucose-induced vascular endothelial dysfunction and could increase the NO release.

Objective:To investigate the clinical features, operative approach and method of petrous apex chol-esteatoma, to improve the effect of operation and to reduce surgical complications. Method:Two cases of patients with giant petrous apex cholesteatoma were treated by trans labyrinth approach,one of which was successfully operated with oto-endoscope-assisted surgery. Result; No cerebrospinal fluid leakage, infection, vertigo or disequilibrium was found in the two cases after operation. Conclusion:Temporal CT and MRI are of great importance in clinical diagnosis and choice of surgical approach. Surgery by trans-labyrinth approach paves way for removing cholesteatoma thoroughly, dealing with facial nerve and repairing cerebrospinal fluid leakage. Surgery is considered to be the only way to cure petrous apex cholesteatoma, while the key procedure to prevent recurrence lies in complete removal of lesion, long-time strict follow up and regular clearance of the surgical field.

Objective To examine the relationship between gender and intraventricular hemorrhage (IVH) in very low birth weight infants (VLBWI) and extremely low birth weight infants (ELBWI).Methods From January 1,1999 to December 31,2012,data on VLBWI and ELBWI,who were admitted to the neonatal intensive care unit of Yuying Children's Hospital within 14 d after birth,were retrospectively collected.The Chi-square test and t test were used to compare neonatal outcomes between male and female infants.The Logistic model was used to analyze the risk factors for IVH.Results A total of 1 008 cases were enrolled,including 615 males and 393 females,895 VLBWI and 113 ELBWI.The incidence of IVH was 15.1％ (152/1 008) and the incidence of severe IVH was 8.4％ (85/1 008).Compared with females,males had a higher total incidence of IVH [17.2％ (106/615) vs 11.7％ (46/393),x2=5.728,P＜0.05] and severe IVH [9.8％ (60/615) vs 6.4％ (25/393),x2=3.896,P＜0.05].These differences were also seen in VLBWI with a birth weight of 1 250 to 1 499 g [IVH:13.7％ (47/344) vs 7.8％ (17/217),x2=4.473,P=0.034; severe IVH:7.6％ (26/344) vs 2.8％ (6/217),x2=5.684,P=0.017].Logistic regression analysis showed that the risk factors for IVH were as follows:gestational age ＜28 weeks (aOR=2.012,95％CI:1.288-3.143,P＜0.05),neonatal respiratory distress syndrome (aOR=l.584,95％CI:1.007-2.492,P＜0.05),invasive mechanical ventilation (aOR=2.743,95％CI:1.826-4.121,P＜0.05),electrolyte disturbance (aOR=2.128,95％CI:1.092-4.149,P＜0.05) and periventricular leukomalacia (aOR=2.901,95％CI:1.312-6.416,P＜0.05),but not male sex (aOR=1.351,95％CI:0.917-1.991,P=0.128).The risk factors for severe IVH were gestational age ＜28 weeks (aOR=2.200,95％CI:1.305-3.708,P＜0.05),invasive mechanical ventilation (aOR=4.714,95％CI:2.809-7.911,P＜0.05) and electrolyte disturbance (aOR=2.232,95％CI:1.047 4.759,P＜0.05),but not male sex (aOR=1.361,95％CI:0.823 2.252,P=0.247).Conclusions Male VLBWI and ELBWI have a higher incidence of IVH and severe IVH,but male sex is not a risk factor for IVH or severe IVH.
