Adipose stem cel s have been confirmed to promote the repair of soft tissue after damage, and the action mechanism is possibly related to the paracrine of adipose stem cel s, that is adipose stem cel s secrete a variety of cytokines, which may promote the restoration of damaged cel s. However, little report addressed the types of adipose stem cel s secreted factors, contents of each factor, and role in soft tissue repair after damage, especial y oral mucosa. To observe the influence of vascular endothelial growth factor, platelet-derived growth factor, and basic fibroblast growth factor in adipose stem cel-conditioned medium on the proliferation of oral mucosa fibroblasts. Protein microarray analysis was used to analyze the contents of vascular endothelial growth factor, platelet-derived growth factor, and basic fibroblast growth factor in adipose stem cel-conditioned medium. CCK8 analysis was used to analyze the effects of adipose stem cel-conditioned medium with different concentrations of vascular endothelial growth factor, platelet-derived growth factor, and basic fibroblast growth factor (0, 1, 10, 20, 50 and 100μg/L) or the neutralizing antibody of the three kinds of cytokines on the proliferation of oral mucosa fibroblast on 1, 2, 3, 4 and 5 days. High contents of vascular endothelial growth factor, platelet-derived growth factor, and basic fibroblast growth factor were contained in adipose stem cel-conditioned medium (signal value>300). Adipose stem cel-conditioned medium could promote the proliferation of oral mucosa fibroblasts, wherein, the promotion effects of platelet-derived growth factor and basic fibroblast growth factor were very significant, and the peak changes could be observed with variation of cytokines concentrations. The optimal concentrations of platelet-derived growth factor and basic fibroblast growth factor were 50μg/L and 1μg/L, respectively (P ≤ 0.05). The neutralizing antibody of platelet-derived growth factor and basic fibroblast growth factor inhibited the promotion effect of adipose stem cel-conditioned medium. On the other hand, vascular endothelial growth factor had no significant effect on the proliferation of oral mucosa fibroblasts. Adipose stem cel-conditioned medium can promote the proliferation of oral mucosa fibroblasts, platelet-derived growth factor and basic fibroblast growth factor in adipose stem cel-conditioned medium have obvious promotion effects, which are dependent on the cytokine concentrations. Therefore, we should pay attention to choose the optimal concentrations of cytokines, thereby effectively promoting the proliferation of fibroblasts.

Objective To study the correlation between the changes of sex hormone level in different perinatal periods and perinatal depression (PND). Methods Between February 2014 and February 2015, 300 pregnant women from the Third Affiliated Hospital of Guangzhou Medical University were enrolled in this study. In the first trimester (12 weeks), the third trimester (34 weeks) and postpartum period (7 and 42 days), blood samples were collected and radioimmunoassay was performed to detect the levels of sex hormones, including estrogen, progesterone, prolactin, luteinizing hormone and follicle-stimulating hormone. Self Depression Scale and Edinburgh Postnatal Depression Scale were used for psychological assessment, and PND was diagnosed by psychiatrists as PND group, and non-PND cases served as control group. Two-sample t-test, variance analysis and Bonferroni test were used to compare the changes of sex hormones at different time points between the two groups. Results A total of 180 pregnant women completed the four stages of research. Fifity-four cases were diagnosed as PND, including 10 cases in the first trimester, 16 new cases in the third trimester, 14 new cases at postpartum 7 days, and 14 new cases at postpartum 42 days. (1) Comparison of the sex hormone levels between the two groups:The estrogen levels of the first trimester, the third trimester and postpartum 7 and 42 days in PND group were (4 107.30±344.68), (13 261.60±593.32), (1 281.70±151.54) and (161.40±12.21) pmol/L, and lower than in the control group [(8 619.60±514.92), (14 330.00±353.15), (3 585.90±150.83) and (270.50±11.86) pmol/L, respectively] (all P<0.05). The progesterone levels of the first trimester and postpartum 7 and 42 days in PND group were (105.49±20.40), (24.23±3.53) and (6.40±3.53) nmol/L, and higher than those in the control group [(85.80±19.06), (5.71±2.36) and (3.87±2.03) nmol/L] (t=-2.389, -2.660 and -2.103, all P<0.05). The prolactin and luteinizing hormone levels of the postpartum 42 days in PND group were lower than in the control group [(9.40±1.69) vs (17.50±1.64)μg/L, t=-4.059;(0.32±0.21) vs (2.21±0.17) mU/L, t=-12.302] (both P<0.05). The levels of follicle-stimulating hormone in the first trimester, the third trimester and postpartum 7 days were not detectable in both groups, but PND group had a lower level at postpartum 42 days than the control group [(2.22±0.58) vs (3.15±0.29) mU/L, t=-15.525, P=0.000]. (2) Sex hormone levels at different time points:There were significant differences in estrogen levels between the four time points in both groups. There was significant difference in progesterone in the PND group at four time points, while in the control group, significant differences were found between postpartum 42 days and the first and third trimester. Prolactin levels were lowest at postpartum 42 days in both groups among the four time points (Bonferroni test, all P<0.05). Conclusions Low estrogen levels and high progesterone levels and their changes in perinatal period may be correlated with PND.

Objective: To explore the correlation among overweight, obesity and markers of prethrombotic state in patients with coronary heart disease (CHD). Methods: A total of 288 patients to hospital from 2013 to 2014 and diagnosed as CHD by coronary angiography were selected. According to body mass index (BMI), they were divided into CHD control group (n=106), overweight group (n=121) and obesity group (n=61). Levels of fibrinogen (Fg), plasma D dimmer (D-D), von Willebrand factor (vWF), antithrombin Ⅲ (AT-Ⅲ) and plasminogen activator inhibitor (PAI)-1 were compared among three groups, then received correlation analysis.Results: Compared with CHD control group, there were significant rise in levels of triglyceride, total cholesterol, fasting blood glucose and mean arterial pressure, morbidity rates of hypertension and diabetes mellitus in overweight group and obesity group, P<0.05 or <0.01. Compared with CHD control group, there were significant rise in levels of Fg [(2.89±0.60) g/L vs. (3.54±0.63) g/L vs. (3.92±0.94) g/L], D-D [(282.13±73.15) ng/ml vs. (390.04±73.54) ng/ml vs. (471.92±80.38) ng/ml], vWF [(108.62±24.66)% vs. (138.45±25.96)% vs. (161.20±29.39)%] and PAI-1 [(6.97±1.28) ng/ml vs. (9.60±1.73) ng/ml vs. (12.33±2.16) ng/ml] in overweight group and obesity group, P<0.01 all, and those of obesity group were significantly higher than those of overweight group, P<0.01 or <0.05; AT-Ⅲ level [(89.94±17.99)% vs. (69.89±20.22)%] significantly reduced in obesity group (P<0.05). Pearson correlation analysis indicated that BMI was positively correlated with markers of prethrombotic state [Fg: r=0.536, P<0.001; D-D: r=0.250, P<0.001; vWF: r=0.611, P<0.001;PAI-1: r=0.788,P<0.001). Conclusion: BMI is positively correlated with markers of prothrombotic state in CHD patients.

Objective To evaluate the right ventricular(RV)systolic function in patients with primary pulmonary hypertension(PPH)using real -time three -dimensional echocardiography(RT -3DE)and ultrasonic two-dimensional speckle tracking imaging(STI).Methods Patients with PPH were divided into three groups according to pulmonary arterial systolic pressure(PASP),consisted of mild group,moderate group and severe group,with 20 cases in each group.20 healthy cases were included as the control group.The global RV dysfunction,including RV end -diastolic volume(EDV),end -systolic volume(ESV),stroke volume(SV),ejection fraction(EF),tricuspid annular plane systolic excursion(TAPSE),longitudinal peak systolic strain(SL),longitudinal peak systolic strain rate(SRL), longitudinal peak systolic velocity(VL)in RV free wall and interventricular septum for basal,mid and apical segment were detected by using RT -3DE and STI.Results Global RV ESV increased in all groups(t =3.10,7.53,7.72,all P <0.01),but The RV EDV in the moderate and severe group was higher than that of normal and mild groups(t =4.02,5.82,3.04,5.15,all P <0.01),the RT SV and EF in all case groups was fewer than that of normal(t =-9.33 ~-2.71,all P <0.05).Linear correlation analysis showed negative correlation between EF and ESV,EDV (r =-0.776,-0.638,all P <0.01).The level of RV free wall peak systolic displacement of tricuspid annulus, ventricular septal annulus peak systolic displacement,tricuspid annulus peak systolic displacement midpoint and the right longitudinal ventricular shortening fraction were significantly lower than those of the control group(all P <0.01). Linear correlation analysis showed positive correlation between EF and TAPSE(r =0.761,0.593,0.745,0.773,all P <0.01).The VL and SL in RV free wall and interventricular septum for basal,mid and apical segment were fewer than the control group(P <0.05 or P <0.01),but SRL of RV for all segments showed no significantly different in all groups(P >0.05).Conclusion RT -3DE and STI technology can be useful in assessing RV function every period.

Objective To screen the anti-nasopharyngeal carcinoma scFv from a human anti-nasopharyngeal carcinoma single-chain phage antibody library, and identify its characteristics. Methods The single-chain phage antibody library was subjected to three rounds of positive and negative cell panning and enrichment, and then it was selected by ELISA. The binding specificity of phage antibodies with naso-pharyngeal carcinoma cells was confirmed by immunohistochemistry. Results After panning, enrichment and testing by ELISA, 3 phage an-tibody clones reacting with CNE2 more strongly than HUVEC and NP69 were picked out from 4212 clones. One clone, HNSAO33, was fur-ther analyzed after DNA sequencing. The results of immunohistochemistry with cultured cells were similar to those of ELISA. HNSAO33 spe-cifically reacted to nasopharyngeal carcinoma cells in most human nasopharyngeal carcinoma tissue sections except a few human normal naso-pharyngeal tissue sections. The distinction of positive rates was of a great statistical significance. Conclusion ELISA and immunohisto-chemistry results confirmed HNSAO33 specifically bind with nasopharyngeal carcinoma cells. The seFv fragment against nasopharyngeal carci-noma may be further developed and applied in clinical diagnosis and therapy of nasopharyngeal carcinoma.
