OBJECTIVE: To investigate whether the allergic factors impact the severity of chronic rhinosinusitis or not, further more, to explore the relationship between allergic rhinitis and chronic rhinosinusitis. METHOD: A retrospective review was done on 103 patients. All of these patients were under functional intranasal endoscopic sinus surgery after expectant treatment is ineffective. We devided the patients into different groups according to the result of skin prick and specific IgE and if there is difference in VAS score, Lund and Kennedy endoscopic score, Lund-Mackay CT score between the groups. We also analysed the symptoms in different chronic rhinosinusitis patients allerged to variant kinds of allergen. The SPSS 17.0 software was used to analyze the data. Statistical analysis was performed by t-test, rank order test or χ2 test. RESULT: The duration of the disease, VAS score of nasal blockage, score of Lund-Mackay CT and Lund and Kennedy endoscopic before the operation were in no statistical sense after when compared with the two groups of patients with chronic rhiriosinusitis who grouped according the result of skin prick and specific IgE. The VAS score of facial pressure and loss of smell was higher in patients with chronic rhinosinusitis which the skin prick and specific IgE were positive. The VAS score of nasal discharge was higher in patients with chronic rhinosinusitis who got negative skin prick and specific IgE result. The symptoms of chronic rhinosinusitis improved with operation no matter the group of skin prick and specific IgE positive or negative and VAS score of nasal blockage improved significantly in negative group. The symptoms of sneezing, rhinorrhoea and rhinocnesmus improved after operation among the chronic rhinosinusitis patients with skin prick and specific IgE. The number of cockroach allergy is larger among the patients with chronic rhinosinusitis without polyps than the one among the patients with chronic rhinosinusitis with polyps. CONCLUSION Allergic factor didn't impact much the severity of chronic rhinosinusitis patients who were failed in expectant treatment, besidesthe postoperative outcomes showed that only influence the severity of nasal discharge, facial pressure and loss of smell. Different kinds of allergen were found between the patients of chronic rhinosinusitis with or without polyps. No significantly functional endoscopic sinusitis sugrery outcome were related to the allergic factor. But the allergic factor may interfere the remission of nasal discharge after surgery.

Objective To investigate the effects of osteopontin (OPN) antisense oligodeoxynucleotide (AS-ODN)on OPN mRNA expressions and adherence to collagen gel of rat renal mesangial cell line (1097). Methods One AS-ODN complementary chain to rat OPN cDNA sequences was designed and synthesized. All nucleotides of different kinds of oligodeoxynucleotide (including antisense, sense and mismatch sense) were modified with phosphrothioate. All the ODNs were mixed with cationic liposome(DOTAP) respectively. The cultured 1097 cells were incubated with different concentration of ODN at 37t for 48 hours, then total RNA was extracted from cultured cell line with Trizol reagent. OPN mRNA expression was detected with RNA dot blot and RT-PCR. The cell adhesion ability was measured with collagen gel attachment lest. Results OPN mRNA expression of mesangial cells was higherly upregulated in the medium with calf serum compare to that in the medium without serum. AS-ODN could suppress the expression of OPN mRNA in mesangial cells with dose-dependent and its lowest inhibitory concentration was 2. 5 ?mol/L, but mismatch ODN or sense ODN have no inhibitory effects on the OPN mRNA expression of mesangial cells even if at a high ODN concentration of 30 ?mmol/L. AS-ODN-treated cells weakly adhered to the collagen gel and could be easily detached off. The mesangial cells treated with mismatch ODN or sense ODN still had a good adherent ability to collagen gel. Conclusions Calf serum can induce rat renal mesangial cells higherly expressing OPN mRNA. Osteopontin antisense oligodeoxynucleotide can specifically suppress mesangial cells OPN mRNA expression and adhension to collagen gel.

CDKs proteins are a kind of cell cycle protein-dependent kinases, which serve as important roles in controlling cell division and transcriptional stages. Among them, CDK9, as a key regulator responsible for the transcriptional elongation of cells, drives the development of various malignant cells and is considered as an important target in the field of anti-tumor drug development. However, the CDK family proteins feature high conservativeness and similarity in structure, leading to the poor selectivity and severe side effects for traditional small-molecular CDK9 inhibitors, which has limited their clinical applications. In view of this, there is an urgent need to investigate CDK9 targets through a novel strategy. The PROTAC is an emerging drug discovery strategy that the degrader could specifically recognize the target protein through indirect linkage with ubiquitin ligases and ultimately eliminate the target protein through the ubiquitination degradation system. This paper provides a brief overview of the structure and function of CDK9 protein, its relationship with the poor prognosis of clinical diseases, as well as the currently reported small molecular inhibitors. The latest research progress on the targeted degradation of CDK9 protein based on PROTAC technology is highlighted. Finally, the development prospects of this target protein in this novel technology field are summarized and prospected, aiming to provide a reference for the development of antitumor drugs in this direction.

Objective To investigate the correlation between angiotensin converting enzyme(ACE) gene polymorphism and kawasaki disease(KD).Methods A 287 bp Alu fragment in intron 16 of the ACE gene was used as insertion(I)/deletion(D) polymorphism marker. The ACE genotype of 28 children (10 children complicated coronary dilataltion) with KD and 35 healthy controls were detected by polymerase chain reaction (PCR), and ACE concentration in blood serum was measured by ultraviolet-spectrophotometer assay.Results 1.The ACE concentration was significantly higher in KD group than that in healthy control group(P
