Background and purpose: Chemokines play an important role in cancer occurrence and development. However, little about the function of CCL26 in esophageal squamous cell carcinoma (ESCC) is reported. This study was designed to observe and study the expression of chemokine CCL26 in ESCC tissues and to analyze their association with pathological features of ESCC. Methods: Expressions of chemokine CCL26 in 197 ESCC tissues and their corresponding paraneoplastic normal esophageal tissues were determined by tissue array and immunohistochemistry (IHC) technique, and its correlations to age, gender, lymph nodes metastasis, TNM stage, general classification and 5-year survival rate of ESCC patients were further analyzed. Results: ①CCL26 was expressed in both ESCC and paraneoplastic normal esophageal tissues. The expression of CCL26 in ESCC tissues was signiifcantly higher than that in paraneoplastic normal esophageal tissues (61.8%vs 20.6%, P<0.05).②The expression of CCL26 was correlated with lymph node metastasis, but not correlated with age, gender, tumor cell differentiation, and general classiifcation (P>0.05).③Survival analysis showed that the abnormal expression of CCL26 was associated with 5-year survival rate of patients with ESCC. The 5-year survival rate of ESCC patients with CCL26 positive expression was obviously lower than that of ESCC patients with CCL26 negative expression. Conclusion: CCL26 upexpression might play an important role in the progression and development of ESCC patients. The high level of CCL26 expression is correlated with lymph node metastasis and poor survival. Detection of CCL26 expression may have important prognostic values in ESCC patients.

Objective To investigate the expression of nestin in fibroblasts of adult human dermis.Methods A total of 6 samples of normal human skin were collected.Immunohistochemistry and immunocytochemistry staining were used to detect the nestin expression in adult human dermis and in cultured fibroblasts of different passages(3rd,5th,7th,10th,and 12th passages,respectively) in vitro.Nestin positive cells were counted to evaluate the expression quantity and intensity.Results There were 103.3?67.4 fibroblasts per square millimeter(mm~2) of adult human dermis,and the nestin positive fibroblasts accounted for(9.5?3.0)% of total amount.The amount of nestin positive fibroblasts in vitro was obviously higher than that in vivo.Significant difference was observed in the amount of nestin expression among different passages(P

Objective To study the effects of valsartan and triptergium glycosides on the abnormal expression of connective tissue growth factor(CTGF) in rats with diabetic nephropathy. Methods Sixty male SD rats were randomly divided into normal control group,diabetic nephropathy group(DN group),diabetic nephropathy treated with valsartan group(VAL group) and diabetic nephropathy treated with triptergium glycosides group(TG group).Diabetic nephropathy model was established by intraperitoneal injection of streptozotocin(STZ) in DN group,VAL group and TG group.The rats were sacrificed after 2,4,8 and 12 weeks.The body weight,blood glucose,renal function and urinary albumin excretion rate(UAER) were measured,and the expression of CTGFmRNA in kidney was detected by RT-PCR. Results Compared with control group,the levels of blood glucose,blood urea nitrogen,serum creatinine and UAER were significantly increased in DN group(P

Objective To observe the effects of Sanjia Yigan Granule (S-JG) on hepatic fibrosis and explore its mechanism related to anti-lipid peroxidation in rats. Methods Forty male SD rats were randomly divided into four groups: normal group, model group, and compound Salviae Miltiorrhizae (Sm) group and S-JG group. Dimethylnitrosamine was injected intraperitoneally for 4 weeks to induce hepatic fobrosis. At the same time of modeling, Sm and S-JG were given in the corresponding groups. The rats were killed after four weeks. The histomorphylogic structure of the liver tissues was observed under optical microscope; the levels of MDA and SOD in serum were determined by radioimmunoassay. Results Compared with those in normal group, the collagen area in Masson staining and level of serum MDA were inreased obviously, and the level of serum SOD was dereased obviously in model group (P

OBJECTIVETo investigate the clinical effect of steroids on reducing postoperative edema in rhinoplasty.

METHODSCochrane, Medline data, Pubmed date, were searched and updated on October 2013. Randomized controlled trials(RCTS) studies were included to assess the efficacy of steroids on decreasing postoperative edema after rhinoplasty. The methodological quality of the included studies was evaluated, and date analyses were performed using the Cochrane Collaboration's software RevMan 5.2.

RESULTSA total of 4 RCTS involved 172 patients with rhinoplasty, including 87 patients in the experimental group( steroid) and 85 paitents in control group (placebo). Meta analysis results showed the edema in experimental group was significantly less than that in the control group on postoperative day 1 and 3 (P < 0.01), while the difference was not significant on postoperative day 7 (P = 0.19).

CONCLUSIONSPerioperative application of steroid in rhinoplasty can significantly reduce periorbital edema in the first postoperative day. The edema can completely be relieved after application of steroid for 3 days. It is a safe and effective way to reduce the postoperative edema.

Objective To study the value of the semiquantitative-parameter analysis of wash out index of time-intensity curve (Swash-out) in evaluating the therapeutic effect of neoadjuvant chemotherapy for locally advanced breast cancer (LABC).Methods Fifty-nine women with LABC underwent dynamic contrast enhancedt MRI examination before chemotherapy,after the 2nd cycle and the 4th cycle of chemotherapy.All patients were divided into major histological response group (MHR) and non-major histological response group (NMHR) according to the final pathologic response.Swash-out and the variancetrends of Swash-out before NAC,after the 2nd cycle of NAC and after the 4th cycle of NAC were compared in each group and between the two groups.According to the gold standard of Miller & Payne criterion,Receiver operating characteristic curve (ROC) analysis was performed to evaluate the predicting effect of Swash-out for NAC response,and to compare it with Semi-quantitative TIC curve indicators Smax (steepest slope) and PPE (peak percent enhancement).Results Fifty-nine patients of LABC patients were divided into a MHR group of 34 patients and a NMHR group of 25 patients.Swash before NAC of MHR group was-16.99 (-56.72-41.20),Swash-out after the 2nd cycle of NAC was 5.66(-69.45-53.08),Swash-out after 4th cycle of NAC was 15.95 (-7.80-54.23).Swash-out before NAC of NMHR group was-23.08 (-64.24-34.39),Swash-out after the 2nd cycle of NAC of NMHR group was-23.01 (-52.72-28.70),Swash-out after 4th cycle of NAC of NMHR group was-11.45 (-50.49-50.93).Swash-out variance rate of MHR group after the 2nd and the 4th cycle of NAC were-1.18 (-31.32-60.86) and 1.50 (-86.27-3.61),respectively.Swash-out variance rate of NMHR group after the 2nd and the 4th cycle of NAC were-0.28(-3.24-9.46) and 0.27 (-5.34-3.11),respectively.Swash-out was not significantly different between the two groups before NAC (Z =-0.97,P ＞0.05).Swash-out and Swash-out variance rate of MHR group after the 2nd cycle of NAC were significant higher than that of NMHR group (Z =-3.97 and-3.02,P ＜0.01).Swash-out and Swash-out variance rate of MHR group after the 4th cycle of NAC were significant higher than that of NMHR group (Z =-3.96 and-3.16,P ＜ 0.01).Area under curve (Az) after the 2nd and the 4th cycle of NAC were 0.805 and 0.804,respectively,and no significant difference was found between them (Z =0.019,P ＞0.05).Diagnostic cut-off points were-8.670 for the 2nd cycle of NAC and 4.105 for the 4th cycle of NAC.Diagnostic sensitivity was 79.42％,specificity was 76.00％ and Youden index was 0.554,for after the 2nd and the 4th cycle of NAC.Conclusion Swash-out of TIC curve before NAC cannot predict the response of NAC,Swash-out of TIC curve after the 2nd cycle of NAC and after the 4th cycle of NAC are efficient in predicting the response of NAC.
