Chronic rhinosinusitis with nasal polyps (CRSwNP) and asthma is a common clinical refractory airway disease. Comprehensive treatment of nasal endoscopic surgery including nasal endoscopic surgery and medication, which can significantly improve nose-pulmonary symptoms and make sinusitis and asthma easier to be controlled by medication, has certain superiority. But the existence of disease heterogeneity of CRSwNP with asthma causes different reactions to the current treatment, which manifests as parts of polyps and asthma easy to recur and difficult to control. According to the research recently, the study of the heterogeneity of airway diseases, for example endotype, is a hot area of research. Endotype is a subtype of a condition, which is defined by a distinct functional or pathobiological mechanism. This is distinct from a phenotype, which is any observable characteristic or trait of a disease. Different Inflammatory subtypes often represent different pathophysiology and even different pathogenesis. The concept of inflammatory subtypes of airway diseases provides a new perspective for studies of airway diseases of endotype and the mechanism of combined airway diseases. This review summarizes recent advances in the clinical characterization and treatment of the CRSwNP with asthma. On this basis, we analyze and summarize the heterogeneity of CRSwNP and asthma separately from the perspective of inflammatory subtypes. Then according to the concept of the combined airway diseases and the common pathogenesis, we put forward the definition of inflammatory subtypes of the CRSwNP with asthma and preliminarily discuss the method of the definition.

Specific antibodies purified from sera of rabbit infected with Toxoplasma gondii were used to immun-oscreen the 12-mer and 7-mer phage random peptide libraries. By 3 rounds of screening, 70 clones were picked out ra-ndomly to test the specificity and 43 were found positive by ELISA. 23 of the 43 positive clones showing strong reaction in ELISA were picked out for sequencing. Clone A7 was selected as mimic antigen in ELISA test after analysis of the 23 short peptide sequences. 23 out of 47 sera from rabbits infected with Toxoplasma gondii were ELISA positive by A7 mimic antigen with a positive rate of 68.1%, and 10 of 155 sera from healthy persons showed false positive with a sp-ecificity of 93.5%. The primary result suggests that mimic antigen may have a potential use in diagnose of toxoplasmosis.

Objective To investigate the changes of thrombomodulin and matrix metalloproteinase-9 in sepsis and determine their significance in the early diagnosis and prognosis of multiple organ dysfunction syndrome. Methods The plasma levels of thrombomodulin and matrix metalloproteinase-9 in 32 ICU patients with sepsis were measured by immunofluorescence. Results Compared with control group,the levels of TM and MMP-9 were significantly higher on the day of the diagnosis of sepsis(P

Objective: To study the effects of herbimycin A on proliferation and NO production stimulated by IL 1 in chondrocytes. Methods: IL 1 alone or in combination with herbimycin A was administered.Chondrocytes proliferation was detected by crystal violet dying method and NO production was detected by Griess method. Results: IL 1 inhibited chondrocytes proliferation. Herbimycin A dose dependently reversed the effect. Also herbimycin A could inhibit NO production induced by IL 1. Conclusion: The reversing effect of herbimycin A on chondrocytes proliferation may be mediated by NO.

Objective: To study the effect of lipopolysaccharides(LPS) on nitric oxide(NO) production in synoviocytes and inhibition of genistein on it.Methods: LPS or LPS+genistein stimulated synoviocytes in vitro .NO in culture medium was determined by Griess method.Results: LPS dose and time dependently induced NO production in synoviocytes; Genistein (6.25 50 ?mol/L) dose dependently inhibited the production of NO induced by lipopolysaccharide.Conclusion:The effect of LPS on NO production can be dose dependently inhibited by genistein,this may be mediated by tyrosine kinase(PTK).

Hydrocortisone-induced yang-deficiency animal model has now become the generally accepted model of yang deficiency. However, assessing the most appropriate dose of hydrocortisone is a long-term challenge. For analyzing the modeling dose, the authors have built several kinds of yang-deficiency models induced by hydrocortisone at different doses, and analyzed the experimental data with various mathematical statistical methods. In order to discuss the effects of the modeling dose on the basis of previous research, the authors introduced Ridit analysis.

Background The main mechanism of diabetic retinopathy (DR) is the formation of retinal neovascularization. Vascular endothelial growth factors (VEGF) is primarily factor for DR. Objective The goal of this study was to investigate the effects of angelicae sinensis decoction for supplementing blood ( ASD), a kind of traditional prescription of Chinese herbal medicine, on vascular endothelial growth factor (VEGF) level in vitreous and serum of STZ-induced type 2 diabetes mellitus. Methods Thirty-four SPF male SD rats were fed using high fat diet for 8 weeks and then the streptozocin of 25 mg/kg was intraperitoneally injected to create the type 2 diabetic models. ASD (3.6 g/kg) and 10 mg/kg Gli of 5 mi were administered intragastrically from the 4th day of high fat die though 8 weeks respectively. Other 10 matched rats were used as normal control group. The body weight, blood glucose level ,triglycerides (TG) and high density lipoprotein (HDL) were detected in 4 and 8 weeks after usage of drug. The vitreous and serum samples were obtained in the 8 th weeks for the VEGF detection by enzyme-linked immunosorbent assay (ELISA). This experiment comlied with the Regulations for the Administration of Affair Concerning Experimental Animals by State Science and Technology Commission. Results The body weight and HDL in DM group were significantly lower than those of normal control group in 4 or 8 weeks ( P＜0. 01 ), but in ASD and Gli groups ,the body weight and HDL were higher than those of the DM group (P＜0. 05 ). the blood glucose level and TG were elevated in DM group compared with normal control group (P＜0. 01 ), but those in ASD group and Gli group were decreased in comparison with DM group ( P＜0.05 ). EIISA revealed that no significant differences were found in VEGF levels between normal control group and ASD group or Gli group (P＞0. 05 ), but in DM group, the serum VEGF level (147.65±4. 55 ng/L) was reduced and vitreous VEGF level (673.45± 100. 85 ng/L) was raised,showing the considerable differences (P＜ 0.05 ). No any correlation was found between serum VEGF level and vitreous VEGF level (r=0.314,P＞0. 05). Conclusion ASD can decrease the VEGF level in vitreous,implying that ASD postpone the occurrence of diabetic retinopathy in DM rat.

Epithelial ovarian cancer is the most lethal gynecologic malignancy, drug?resistance will eventually appear after re?peated intermittent chemotherapy. However, second?line chemotherapy only works on a few patients, new drugs with better efficacy and less side effects are needed. There are a number of promising results of molecular targeted therapy in recent clinical trials for patients with recurrent epithelial ovarian cancer, such as Bevacizumab, Olaparib, Pazopanib, etc. They have been demonstrated to improve progression?free survival of patients with platinum?resistant ovarian cancer, which might become a new strategy for such patients. In this review, we summarized the current status and progress of targeted therapy for recurrent epithelial ovarian cancer.

Objective:To evaluate the effect of thermocycling on nano-silver-incorporated silicone denture liner for Candida albicans (CA)adhesion.Methods:Specimens(1 0 mm ×1 0 mm ×3 mm)of silicone denture liner(control)and that incorporated with nano-sil-ver were prepared according to the manufacturer's direction.8 of the each kind of specimens were immersed in distilled water for 24 h at 37 ℃,and 8 were subjected to thermocycling for 4 000 cycles at temperatures ranging from (5 ±1 )℃to (55 ±1 )℃with a 60 s dwell time per temperature.In vitro CA adhesion assay was used to measure the levels of adherence to the specimens.Data were analysed sta-tistically.Results:Thermocycling increased CA adhesion to control specimens(P<0.05),and did no change the adhesion to nano-sil-ver incorporated specimens(P>0.05 ).The adhesion of CA to nano-silver incorporated specimens was fewer than that to the controls with or wihout themocycling(P<0.01 ).Conclusion:Nano-silver incorporation may inhibit CA adhesion to silicone denture liner.Ther-mal cycling has no influence on C.albicans adhesion to silicone denture liner incorporated nano-sliver.
