Objective To investigate the effect of Biyankang Tablets on quality of life and recurrence rate in patients with chronic rhinosinusitis after functional endoscopic sinus surgery (FESS). Methods A total of 78 patients with chronic rhinosinusitis treated in our hospital during October 2014 to November 2016 were selected, and they were randomly divided into the control group and the traditional Chinese medicine (TCM) group according to the order of admission, with 39 cases in each group. Both groups were treated with FESS, and the TCM group was additionally treated with Biyankang Tablets. The clinical efficacy, inflammatory factors [interleukin-4 (IL-4), interleukin-8 (IL-8)], the prognosis [visual analogue scale (VAS) score of rhinosinusitis and the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30)], drug safety and recurrence rates in the two groups were observed. Results After treatment, the total effective rate of treatment in TCM group was significantly higher than that in the control group (89.74% vs 71.79%) (χ2=4.044, P<0.05). After treatment, IL-4, IL-8 and VAS scores in the two groups were significantly decreased, and the scores of EORTC and QLQ-C30 were significantly increased, and the changes of scores in TCM group after treatment were more significant than those in the control group (P<0.05). After treatment, there was no significant difference in the incidence of adverse reactions between the two groups, and the recurrence rate in TCM group was significantly lower than that in the control group in 1 year after treatment (P<0.05). Conclusion TCM Biyankang Tablets is significantly effective in the treatment of patients with chronic rhinosinusitis after FESS. It can significantly inhibit the expression of inflammatory factors, effectively improve the prognosis and quality of life, and significantly reduce the recurrence rate.

Objective The aim of this study was to elucidate the effects of homocysteine (Hcy) on the expression and secretion of tissue factor pathway inhibitor (TFPI) in endothelial cells (Ecs). Methods Cultured human umbilical vein endothelial cells (HUVECs) (ECV-304 strain) were incubated with homocysteine (Hcy) in different concentrations of 0, 25, 50, 100?mol/L, and 1,5,10mmol/L, respectively, for 24 hours. Cell viability was then determined by MTT assay, and lactate dehydrogenase (LDH) released into the culture medium was measured to assess cell damage. Antigen levels of the free form of TFPI after Hcy exposure were measured in culture media with ELISA (Diagnostica Stago, France). Furthermore, the total content of TFPI was assessed with cellular ELISA. Results Hcy in concentrations of 0～1mmol/L did not produce cell toxicity as shown by cell viability and LDH determination in culture media after 24 hours of incubation. When the endothelial cells were exposed to concentrations up to 5mmol/L, cell viability decreased, and a higher concentration of Hcy (10mmol/L) elicited a significant cytotoxic effect, as shown by a decreased cell viability and a higher amount of LDH in culture supernatants compared with the control cells. All the TFPI absorbance values in Hcy-treated cells and the free TFPI levels in culture supernatants were significantly increased, especially in the 50?mol/L group. Conclusion A lower concentration of Hcy did not show signs of cell toxicity but it could promote the expression and secretion of TFPI. The results can help us partly explain why the TFPI level was increased in some patients with hyperhomocysteinemia. They also suggested that Hcy could play an important role in the modulation of coagulation processes in blood circulation.

Objective To investigate behavioral disposition of nurses in emergency room and analyze influential factors.Methods A total of 200 nurses from the emergency room participated in the survey using demographic questionnaire and the nursing behavior questionnaire.Results The total average score of the nursing behavior was(3.13±0.54),and the influential factors included the level of hospital,the time span for the job and the continued education on the infectious diseases(all P<0.01).Conclusions The nursing behaviors was at the medium level.The nursing administrators should provide the nurses with personal protection apparatus,strengthen education on infectious diseases and use incentive mechanism so as to improve the ER nurses' nursing behavior.

Objective To study the effects of the HBV x gene (HBx) on the biological characteristics and the expression of DNA repair enzyme hMTH1 mRNA of the L02/HBx transgene cell model. Methods Light microscopy was used to observe the morphologic characteristics of gene-transfected cell strain Lff2/HBx that stably expressed the HBx protein and the control groups of L02 and L02/PcDNA3.1. The changes of L02/HBx on the proliferation, cell cycle and apoptosis were observed by MTT assays and flow cytometry analysis respectively. Moreover, the malignant transformation of L02/HBxwas assayed by colony formation in soft agar and the expression of DNA repair enzyme hMTH1 mRNA was assayed in each group by real-time qPCR. Results Inversion phase contrast microscope showed that the morphologic characteristics of L02/HBx had changed obviously compared with control groups. The MTT showed that L02/HBx proliferated more quickly and flow cytometry analysis indicated that HBx could accelerate the progression of cell cycle and inhibit apoptosis. Colony formation in soft agar demonstrated that the rate of colony formation of L02/HBx was remarkably higher than the L02 and the L02/peDNA3. 1 cells (P<0. 05). The real-time qPCR detection showed that the expression of hMTH1 mRNA in L02/HBx was significantly higher than that in the control groups ( P < 0. 05 ). Conclusion HBx could play an important role in the malignant transformation of L02/HBx and the over expression of hMTH1 mRNA.

To observe the alteration in the expression of DNA repair enzymes hOGG1 and hMYHalpha and the change in 8-OHdG levels in the HBx gene-transfected cells HepG2/HBx and to explore the mechanisms of the HBV-associated hepatocellular carcinoma, the gene-transfected cells HepG2/HBx which stably expressed HBx was established, and the effect of HBx on the cell cycle and proliferation of HepG2 was examined. By using the beta-actin as the interior control, real-time polymerase chain reaction (Real-time qPCR) was employed to quantitatively detect the expression of DNA repair enzymes hOGG1 and hMYHalpha in the HepG2/HBx, the control cells HepG2 and HepG2 transfected with pcDNA3.1 vector (HepG2/pDNA3.1). The 8-OHdG levels were determined by HPLC/ECD in the established gene-transfected cells HepG2/HBx and the control cells HepG2 and HepG2/pcDNA3.1. Our results showed that the expression of DNA repair enzyme hMYHalpha in the HepG2/HBx (0.021+/-0.007) was significantly lower than that of HepG2 (0.099+/-0.041) (P<0.05) and HepG2/pDNA3.1 (0.121+/-0.005) (P<0.05). However, the no significant differences existed in the expression of DNA repair enzyme hOGG1 among the three cell strains (P>0.05). The 8-OHdG level in the HepG2/HBx was significantly higher than that in HepG2 and HepG2/pcDNA3.1 (P<0.05). It is concluded that HBx gene may inhibit the expression of DNA repair enzyme hMYHalpha mRNA to impair the ability to repair the intracellular DNA oxidative damage, to increase the oxidative DNA-adduct 8-OHdG and to affect the nucleotide excision repair function, thus participate in the occurrence and development of hepatocellular carcinoma.

Background Our previous studies found that mesenchymal stem cells (MSCs) can ameliorate experimental autoimmune uveitis (EAU) and reduce tissue impairment.Its mechanism is still pending.Objective This study was performed to investigate the effects of MSCs on T cell subsets and antigen presenting cells (APCs) in EAU rats.Methods MSCs were isolated from bone marrow of six male Wistar rats and cultured by plastic adherence method.Twelve female Lewis rats were assigned randomly into MSCs group and PBS group.EAU rat model was induced by immunization with 200 μl emulsion containing 30 μg interphotoreceptor retinoid-binding protein (IRBP) 1177-1191 polypeptide fragment R16 and complete Freund adjuvant (CFA).The eye manifestations of the rats were observed and scored under the slit lamp microscope after modeling.The R16-immunized rats were treated intravenously with 5×106/ml MSCs for 3 consecutive days from day 9 to 11 after modeling in the MSCs group,and the equivalent volume of PBS was used with the same way in the PBS group.Fifteen days after modeling,the spleens and draining lymph nodes were collected to evaluate the proportion of interferon-γ (IFN-γ) positive CD4+ T cells,interleukin-17 (IL-17)positive CD4+ T cells and forkhead helix transcription factor p3 (Foxp3) positive CD4+ T cells by flow cytometry.The T cells and APCs from the different groups were cocultured and divided into PBS cocultured group,MSCs cocultured group, PBS-MSCs cross-cultured group and MSCs-PBS cross-cultured group under the stimulation of R16 at the concentration of 0.3,1.0 or 10.0 μg/ml, and the proliferation indexes of the T cells in different groups were assayed by 5-bromodeoxyuridine (BrdU) Elisa kit.The use of experimental animals complied with the regulations on the management of experimental animals promulgated by the national science and technology commission.Results The ocular surface inflammatory scores of 11,12,13 and 14 days after modeling in the MSCs group were significantly lower than that in the PBS group (t=3.825,5.100,4.250,3.400, all at P＜0.05).Compared with the PBS group, the proportions of IFN-γ positive CD4+ T cells in spleen and draining lymph notes were considerably decreased in the MSCs group (t =5.651,4.376, both at P＜0.05) , so were the IL-17+ CD4+ T cells (t =3.300,4.925, both at P＜0.05).However,the proportions of Foxp3 + CD4+ T cells in spleen and draining lymph notes were statistically raised in the MSCs group compared with the PBS group (t =-5.172,-2.825,both at P＜0.05).The proliferation index of T cells increased with the rise of R16 dose in the PBS cocultured group, and the proliferation indexes were all declined in the MSCs cocultured group compared with the PBS cocultured group under the stimulation of 0.3,1.0 and 10.0 μg/ml of R16 (P =0.027,0.000,0.000).In addition, significant reduces of proliferation indexes of T cells were seen in the PBS-MSCs cross-cultured group and MSCs-PBS cross-cultured group in comparison with the PBS cocultured group when stimulated by 1.0 μg/ml and 10.0 μg/ml R16 (1.0 μg/ml R16 : P =0.001,0.000;10.0 μg/ml R16:P=0.000,0.000).Conclusions MSCs can ameliorate EAU by inhibiting the functions of antigen-specific T cells and APCs and up-regulating T regulatory cells in EAU rats.

Objective To investigate the current status and changing patterns of hemodialysis in Wenzhou areas of China from 1999 to 2006. Methods Data of blood purification centres of 18 hospitals in Wenzhou areas from 1999 to 2006 were collected. The incidence, prevalence, mortality, the etiology and the relevant factors such as age, gender, dialysis ages, outcomes and causes of death in end stage renal disease(ESRD) patients on hemodialysis(HD) were analyzed retrospectively. Results The incident number and the number of patients increased annually while the mortality remained steady. The male patients outnumbered the female every year, but the male/female ratio was decreasing. The percentage of both young and oldly patients was increasing. The first cause was chronic glomerulonephritis, although the constituent ratio of glomerulonephritis decreased year by year. The constituent ratio of diabetic nephropathy and hypertensive nephropathy increased. The constituent ratio of dialysis age 1-2 years group decreased, ≤1 year, 2-3 years, 3-4 years groups were relatively steady, and 4-5 years, 5-10 years, 10 years groups increased. The number of patients receiving renal transplantation and transferring to peritoneal dialysis increased annually. The leading cause of death was cardiovascular incidence (19.9%), followed by cerebrovascular disorder (10.8%), systemic failure (10.8%), hemorrhagic diseases(4.7%) and infectious diseases(4.3%). The constituent ratio of cardiovascular incidence and cerebrovascular disorder were relatively steady. The constituent ratio of hemorrhagic diseases and systemic failure showed great fluctuation. The constituent ratio of infectious diseases and malnutrition was decreasing. Conclusions In Wenzhou area from 1999 to 2006, the patients number has been increasing annually. The onset age of HD is 30-70 years old, and proves a younger tendency and older tendency. The leading cause is chronic glomeralonephritis. The constituent ratio of diabetic nephropathy and hypertensive nephropathy rises year by year. The long-term survival rate of HD patients is improved. The leading cause of death is cardiovascular accident.
