OBJECTIVE: To analyses the causes and prevention of systemic complications of functional endoscopic sinus surgery (FESS) in patients with chronic rhinosinusitis. METHOD: Three typical cases were reported including their medical history, preoperative diagnosis, medications during preoperational period, complications and treatment. The causes and preventive measures of systemic complications were analyzed. RESULT: Three patients were all suffered from chronic rhinosinusitis with nasal polyps (CRSwNP). After FESS, 1 case was complicated with coma and hyponatremia, 1 case with acute myocardial infarction, and 1 case with lower extremity deep venous thrombosis. The patient with coma and hyponatremia was soon waked after intravenous infusion of 10% sodium chloride. Two patients with acute myocardial infarction and lower extremity deep venous thrombosis were soon completely rehabilitated after emergency thrombolytic therapy and endovascular intervention. Three patients were completed recovered from their systemic complications without any severe sequela. CONCLUSION Systemic hemostatic drugs should be banned in patients with hypercoagulable state in perioperation period of FESS in order to avoid severe systemic complications. Timely vascular interventional treatment can prevent severe sequels.

Objective To explore the role of caveolin-1 in nonalcoholic fatty liver disease (NAFLD) caused by high-fat diet.Methods A total of 12 ten-week-old male C57BL/6 mice were fed with high-fat and high-cholesterol diet for 14 weeks to establish the NAFLD animal model.And six syngeneic mice fed with normal diet at the same time were taken as control.All the mice were sacrificed by the end of 14th week,body weight,liver weight and the changes of serum lipids of the two groups were compared.The changes of caveolin-1 at mRNA and protein levels in the liver of mice with NAFLD were detected by quantitative polymerase chain reaction (qPCR) and Western blot.The liver steatosis of the mice was observed under light microscopy after stained by hematoxylin and eosin.The changes of distribution of caveolin-1 in liver were examined by immunohistochemistry.The differences of caveolin-1 at mRNA and protein level in livers between the two groups were compared by t test.The differences of immunohistochemical scores of caveolin-1 expression in the livers of mice with different degree of fatty liver were analyzed by ordinal variables of two independent samples ranksum test analysis.Results After 14 weeks high-fat and high-cholesterol diet,all the mice of experiment group developed NAFLD.Nine of which were severe and three were moderate.Compared with the control group,serum total cholesterol,high density lipoprotein cholesterol and low density lipoprotein cholesterol of experiment group significantly increased ((1.940 ± 0.300) mmol/L vs (3.771±0.800) mmol/L,(1.120±0.066) mmol/L vs (2.224±0.420) mmol/L,(0.510±0.191) mmol/L vs (1.241±0.660) mmol/L,t=-3.760,-5.474,-3.332,all P＜0.01),however there was no significant difference in triglyceride (P＞0.05).The caveolin-1 of experiment group significantly increased at mRNA (1.536 ±0.226 vs 0.980± 0.272,t=3.371,P＜0.05) and protein levels (0.643±0.240 vs 0.100±0.130,t=4.847,P＜0.01).The immunohistochemical results indicated that the increased caveolin-1 expression mainly distributed in the membrane of hepatocytes,cytoplasm and membrane of lipid droplets.Conclusion The up-regulated caveolin-1 expression in the livers of NAFLD mice induced by high-fat and high-cholesterol may be involved in the mechanism of NAFLD.

OBJECTIVE: To analyze the causes of misdiagnosis in patients with familial nasal bleeding and to improve the level of diagnosis and treatment. METHOD: The clinical characteristics of 7 families with nose blood were analyzed retrospectively and 2 typical cases were reported, including their treatment and misdiagnosis in consulting, out-patient and in-patient. RESULT: Typical case 1 was misdiagnosed and mistreated for 42 years, misdiagnosed as blood disease so that the patient was biopsied in bone marrow, misdiagnosed as endometriosis so that the patient was performed uterus resection. Typical case 2 was misdiagnosed and mistreated for 17 years, misdiagnosed as upper digestive tract hemorrhage so that the patient was performed endoscopic sleeve ligation, misdiagnosed as inferior turbinate hemangioma so that the patient was performed nasal endoscopic surgery. CONCLUSION Neglect of family history and the typical signs are the causes of misdiagnosis. So asking about the family history and checking for the typical signs in patients with nose blood can avoid misdiagnosis.

Gingival recession is one of the common oral symptoms. Periodontal soft tissue defects caused by gingival recession and problems related to aesthetics, prosthetics and orthodontic treatment have garnered increasing attention. This article reviews the etiology, classification and treatment of gingival recession to provide a reference for the diagnosis and treatment of gingival recession. Anatomical characteristics of teeth, bacterial and viral infection, Occlusion trauma, Improperbrushing methods and other daily behaviors and iatrogenic factors may lead to gingival recession. Miller classification is the most commonly used classification standard. It is divided into 4 degrees according to the relationship between gingival recession and the association between the gingival membrane and the loss of adjacent alveolar bone or interdental papilla. Gingival surgeries, such as coronally advanced flap, laterally positioned flap, subepithelial connective tissue graft for Miller Ⅰ degrees and Ⅱ gingival recession retreat, obtain a more satisfactory success rate. Regarding the Ⅲ degree gingival recession, the postoperative curative effect is poor and can only cover part of the root. Regarding Ⅳ degrees gingival recession, surgery cannot reach the root surface coverage. For patients with Miller Ⅳgingival recession caused by severe periodontitis, the surgical treatment is poor, and repair methods, such as sputum, can also be considered. In recent years, a variety of biological materials have been jointly applied to gingival surgery, such as tooth enamel matrix derivative (EMD), allograft acellular dermal matrix (ADM), porcine collagen matrix (PCM) and platelet-rich fibrin (PRF). The use of these biomaterials can improve root coverage, increase gingival thickness and keratinized gingival width, avoid the requirement of palatal flap removal, reduce the surgical risk and increase patient compliance.

Objective: To compare the staining effect of coffee and red tea to the different denture base materials, and to investigate the cleaning efficacy of four denture cleansers. Methods : All samples were separately soaked in 1％NaClO、 Efferdent、 Polident partial and Polident overnight for 12 times within 12 days after staining by the coffee and red tea. Then, the color values of the samples were measured by the spectrocolorimeter. Results : The staining effect between coffee and red tea in the two materials was statistically significant (P < 0.05); the invisible denture materials are easily colored than heat-curing denture base resins (P < 0.05); there was also a statistical difference in the cleaning effect of the denture cleaning agents at each cycle stage (P < 0.05); the trend is different in different phases of color difference (ΔE) (P < 0.05). Conlusion Compared with the Polident partial, the cleaning efficacy of 1％NaClO、Efferdent and Polident overnight were better.
