OBJECTIVE: To investigate the function of activator protein-1 (AP-1) in proliferation and collagen synthesis of cardiac fibroblasts (CFs) in neonatal rats induced by tumor necrosis factor-alpha (TNF-alpha), and to explore the mechanism of Qiangxin Decoction (QXD), a compound traditional Chinese herbal medicine, in reversing cardiac fibrosis. METHODS: CFs derived from neonatal rats were cultured with enzymatic dissociation, and fibrosis of the CFs was induced by TNF-alpha. The CFs were divided into normal control group, untreated group, 5% QXD-containing serum group, 10% QXD-containing serum group and 20% QXD-containing serum group. After 24-hour culture of QXD-containing serum, AP-1 mRNA was detected by real-time fluorescent quantitative polymerase chain reaction; proliferation and collagen synthesis of CFs were assayed by thiazolyl blue assay (MTT) and measured by hydroxyproline respectively, in order to determine the effect of different dosage decoction on the proliferation and collagen synthesis of CFs. RESULTS: After 24-hour stimulation of TNF-alpha in CFs, compared with those in normal control group, the expression of AP-1 mRNA and cardiac fibroblast proliferation and collagen synthesis increased significantly (P<0.05). However, Qiangxin Decoction could reduce the expression of AP-1 mRNA and decreased the proliferation and collagen synthesis of CFs significantly (P<0.05). CONCLUSION: Qiangxin Decoction can inhibit proliferation and collagen synthesis of CFs induced by TNF-alpha, and reverse cardiac fibrosis, which may be related to its down-regulation of the expression of AP-1.

Objective If IL-2 and IFN-? are united,perhaps we may see a more significant antitumor effect.A fusion gene of IL-2 and IFN-? was designed and constructed by DNA engineering.Methods CEA promotor、IL-2cDNA and IFN-?cDNA were obtained by PCR and RT-PCR.SDS-PAGE was used to examine the results;pcDNA-IL-2、pcDNA-IFN-?、pCEA-IL-2/ IFN-?、pEGFP-IL-2/ IFN-? were transfected to CEA high expression cell line(Lovo)by use of liposome.The fusion protein expression was examined by fluorescence microscope and Western blotting.Results IL-2/ IFN-? fusion gene can be expressed in tumor cells.Its expression is more obvious in CEA high expressed cells(Lovo),and can be located in cell plasma.Conclusion The fusion gene can be expressed in plasma of CEA high expressed cell lines.It may have a new anti-tumor effects.

It is necessary to have a research on dental fluorosis in a population to minimize the prevalence and severity of caries.It is important to research the pathogenesis of enamel fluorosis and prevention and control of dental fluorosis and caries.This article reviews the progress in chemistry and biology of dental fluorosis.

Objective To investigate the impact of psoriacis on quality of life in patients with psoriasis. Methods A questionnaire interview included daily life and activities social activities and psychologic status were conducted of. Results 48 patients, 14 patients(29%) were impacted on quatity of life in heavy, 23 patiemts(48%) in middle, 11 patients(23%) in mildly no impact in zero. Conclusion The psoriasis valgaris influenced the Quality of life.

As a kind of cytoskeleton protein,vimentin is a major member of intermediate filament family.Vimentin is found mainly in mesenchymal cells,and its expression and phosphorylation are regulated by many factors.In the past,vimentin was revealed as a scaffold maintaining cellular integrity,and recent studies shed lights on the evidence that vimentin played many important roles in cellular adhension,growth,apoptosis,cell signaling as well as inflammatory response.This article summarizes the recent progress of vimentin about its expression and function.Abstract:SUMM ARY As a kind of cytoskeleton protein,vimentin is a majormember of intermed iate filament fam i-ly.V imentin is found mainly in mesenchymal cells,and its expression and phosphorylation are regulated by many factors.In the past,vimentin was revealed as a scaffold maintaining cellular integrity,and re-cent stud ies shed lights on the evidence that vimentin played many important roles in cellular adhension,growth,apoptosis,cell signaling as well as inflammatory response.This article summarizes the recent progress of vimentin about its expression and function.

The clinical data and ultrasound findings of 185 patients with thyroid nodules undergoing thyroidectomy from June to December 2015 were retrospectively reviewed.Postoperative pathology confirmed malignant thyroid nodules in 86 cases and benign nodules in 99 cases.The ultrasonographic findings showed that there were significant differences in obscure boundary [51％ (44/86) vs.16％ (16/99)],hypoecho [(95％ (82/86) vs.27％ (27/99)],internal micro-calcification [63％ (54/86) vs.21％ (21/99)] and lymph node enlargement [33％ (28/86) vs.5％ (5/99)] between malignant and benign nodules (all P ＜ 0.05).The sensitivity,specificity,positive predictive value,negative predictive value and accuracy of thyroid imaging reporting and data system (TI-RADS) in differentiation of malignant and benign thyroid nodules were 77％ (66/86),86％ (85/99),83％ (66/80),81％ (85/105) and 82％ (151/185),respectively.The positive rates of thyroid globulin antibody(TGAb) and thyroid peroxydase antibody (TPO-Ab) in malignant nodules [6％ (5/79) and 25％ (20/79)] were significantly higher than those in benign nodules [0 (0/94) and 12％ (11/94)] (both P ＜0.05).There was no significant difference in free T3 (FT3),free T4 (FT4) and TSH between the two groups [(4.91-± 0.78) vs.(4.93-± 1.98) pmol/L,(13.57 ±2.22) vs.(13.58 ±2.17)pmol/Land(1.78±1.40) vs.(1.88±2.36)mU/L] (allP＞0.05).The results indicate that TI-RADS grading and thyroid immunity index are valuable for differential diagnosis of thyroid nodules.

Objective To study the effect of reconbinant growrh hormone(rGH) on the tumor cell proliferation in the transplantation liver tumor models in rats,to explore the advantages and disadvantages of rGH in the treatment of liver carcinoma.Methods The male weaning rats were used to vaccinate and transgenerate by intraperitoneal injection of abdominal fluid contarning tumor cells from the celiar transplantation tumor rats, the others weaning rats were used to be the solid tumor rats by subcutaneous vaccination with abdominal fluid of tumor cells.The solid tumor were divided into pieces (2 mm?2 mm?3 mm),which were inserted into the liver of the 82 adult male rats to establish the transplantation liver tumor models.and then the models were divided into experimental group and control group randomly.After 3 days,experimental group were given rGH (0.5U/ kg?d)and control group were given via caudal vein NS for 5 days.All the rats were killed in 8d,10d,12d,respectively.The rats, tumors and livers were weighted,the number of hepatocytes,carcinoma cells and mitotic index were measured,the number of 3 H-TdR incorporation in vivo was measured in 8 days after operation. Results There were no significant difference in all the results between the two groups,except the rat's weight of 8days after operation and the tumor weight in different phase.Conclusions The rGH has no significant effect on the proliferation of tumor cell in transplantation liver models in rats.
