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

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

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 investigate the efficacy and safety of clopidogrel hydrogen sulfate plus nimodipine in treating transient cerebral ischemic attack.Methods A total of 159 outpatients and inpatients with transient cerebral ischemic attack in the neurosurgery department and the neurology outpatient department of our hospital from January 1,2012 to September 1,2016 were divided into 3 groups.The group A(43 cases) orally took clopidogrel hydrogen sulfate plus aspirin;the group B (51 cases) treated with oral clopidogrel hydrogen sulfate plus nimodipine;the group C(65 cases) was treated with clopidogrel hydrogen sulfate plus nimotop.The curative effects were observed in 3 groups.The differences of PT.APTT,FIB and PLT in 3 groups were compared between before and after treatment.Results The total effective rate of the group A and C was significantly better than that of the group B(P<0.05),the curative effect had no statistical difference between the group A and C (P>0.05);the effect of the group B and group C on coagulation was superior to that of the group A(P<0.05).The three group had no severe bleeding events(cerebral bleeding,etc.),the difference was statistically significant.Conclusion Clopidogrel hydrogen sulfate combined with nimotop can significantly reduce the frequency of transient cerebral ischemic attack,has little influence on the coagulation indicators,and is safe and effective.

Long-term treatment with an agonist of peroxisome proliferator-activated receptor (PPAR)-γ is associated with bone fractures in the clinical practice. However, the mechanisms underlying the fractures are not fully understood. This study was aimed to examine the effect of rosiglitazone (an agonist of PPAR-γ) of different doses on the proliferation, differentiation, and transforming growth factor beta 1 (TGF-β1)-induced expression of connective tissue growth factor (CTGF) in primary rat osteoblasts in vitro. Osteoblasts were isolated from newly born SD rats and treated with different doses of rosiglitazone (0-20 μmol/L). The proliferation and differentiation of osteoblasts were measured by MTT assay and NPP assay, respectively. The expression of CTGF was determined by RT-PCR and Western blotting. The results showed that most isolated osteoblasts displayed strong alkaline phosphatase (ALP) activity and treatment with different doses of rosiglitazone did not affect their proliferation, but significantly inhibited the differentiation of osteoblasts in a dose-dependent manner. Moreover, treatment with different doses of rosiglitazone significantly reduced the TGF-β1-induced CTGF mRNA transcription and protein expression in a dose-dependent manner in rat osteoblasts. It was concluded that the activation of PPAR-γ may inhibit the differentiation of osteoblasts by reducing the TGF-β1-induced CTGF expression in vitro.
