Odontogenic maxillary sinusitis(OMS)is a subtype of maxillary sinusitis(MS).It is actually inflammation of the maxillary sinus that secondary to adjacent infectious maxillary dental lesion.Due to the lack of unique clinical features,OMS is difficult to distinguish from other types of rhinosinusitis.Besides,the characteristic infectious pathogeny of OMS makes it is resistant to conventional therapies of rhinosinusitis.Its current diagnosis and treatment are thus facing great difficulties.The multi-disciplinary cooperation between otolaryngologists and dentists is absolutely urgent to settle these questions and to acquire standardized diagnostic and treatment regimen for OMS.However,this disease has actually received little attention and has been underrepresented by relatively low publication volume and quality.Based on systematically reviewed literature and practical experiences of expert members,our consensus focuses on characteristics,symptoms,classification and diagnosis of OMS,and further put forward multi-disciplinary treatment decisions for OMS,as well as the common treatment complications and relative managements.This consensus aims to increase attention to OMS,and optimize the clinical diagnosis and decision-making of OMS,which finally provides evidence-based options for OMS clinical management.

Bronchiectasis is a complex and heterogeneous group of diseases with their own characteristics in terms of etiology, symptoms, infections and inflammation, among which infections are both the most common cause of bronchiectasis and the most important factor contributing to the progression of the disease and affecting the prognosis. The current paper will focus on the characterization, diagnosis and treatment of pathogenic bacteria in bronchiectasis.

Objective To investigate the relationship between pulmonary arterial ( PA) enlargement and pulmonary function in patients with chronic obstructive pulmonary disease (COPD).Methods From December 2012 to June 2016,78 patients with acute exacerbation of COPD in the Eighth People＇s Hospital of Qingdao were selected. According to pulmonary CT findings,they were divided into two groups : PA enlargement group (38 cases) was PA＞3.0cm,normal PA group(40 cases) was PA≤3.0cm.FEV1and FVC of stable phase were compared.Results The FEV1of men in the A enlargement group was (1.08 ±0.44)L,that in the normal PA group was (1.44 ±0.66)L,the difference was statistically significant (t＝2.27,P＝0.028).The FEV1of women in the PA enlargement group was (0.90 ±0.41)L,which in the normal PA group was (1.35 ±0.58)L,the difference was statistically significant (t＝2.28,P＝0.026).Correlation analysis showed that the diameter of PA was negatively related with FEV 1/FVC(r＝-0.509,P＝0.001),PA enlargement was related with lung function decline.Conclusion COPD patients with PA enlargement are more associated with accelerated loss of lung function and should be treated early.

We reported a case of pulmonary capillary hemangiomatosis (PCH) and introduced its diag-nosis, differential diagnosis, pathogenesis and development of treatment based on the review of Dana Point 2008 Classification of Pulmonary Hypertensiona and current literatures .A 43-year-old female presented progressive dyspnea, elevated pulmonary arterial pressures and CT pulmonary angiography (CTPA) imaging of main pulmonary arterial enlargement and wide spread ill -defined centrilobular nodules of ground-glass opacity.Her histologic features were proliferation of capillary channels within alveolar walls as well as muscularization of arterioles and medial hypertrophy of muscular pulmonary arteries.The treatment with diuretics and warfarin was used promptly , but unfortunately was ineffective. The patient died three months after diagnosis .PCH is a very rare vascular disease with poor prognosis . The diagnosis of PCH rests on the integration of clinical and radiographic information with pathologic fea -tures, however pathology is the most reliable means .Because clinical symptoms, imaging and histological features of pulmonary veno-occlusive disease (PVOD) and PCH broadly overlap, differential diagnosis should be made carefully.Among the various pathologic features proliferation of capillaries within alveolar walls is the key point for diagnosing PCH , which is also the most critical criteria for differentiating PCH from PVOD.So far the only definitive treatment for PCH is lung transplantation , without which the pa-tient will die several months after diagnosis .

Objective: To analyze the current situation and effect of vertical integrated of rural health services in Dafeng County. Method: Policy documents and data are collected and interviews are implemented for studying the integrated situation. Results: The vertical integration in Dafeng County is virtual joint form with forming 6 city-level medical volunteer service teams and 52 health management teams. With the imple-mentation of fully integrated management, signing service with rural doctor mode is carried out, which pro-mote the establishment of rural unified service standards and regulations. Using health card of residents which promote the regional shared of treatment information. Conclusions: Vertically integrated mode had connection in health management teams, supported by fully integration, developed by signing service with rural doctor and carried by residents’ health card, which could provide reference for implementing vertical integration of rural health service. But strategies needed to be strengthened in improving health services’ ability of township hospitals, clarifying interest relationship as well as integrating health service regulations and strengthen the health information system for sharing and docking.

Objective To improve the diagnosis and treatment of pulmonary cryptococcosis.Methods The clinical data of 3 cases of pulmonary cryptococcosis were analyzed and reviewed.Results The cases were tested by percutaneous lung biopsy and were confirmed by histopathologic examination.The sputum cultures were negative and serum latex cryptococcal antigen agglutination tests were positive.Two of them had mild to moderate symptoms and were treated by fluconazol;the other with meningitis had severe symptoms and was treated by amphotericin B.All of them were clinically cured.Conclusion Percutaneous lung biopsy combined with latex cryptococcal antigen agglutination tests is helpful for diagnosis of pulmonary cryptococcosis.Patients with mild to moderate symptoms should be firstly treated by fluconazol and those with severe symptoms or meningitis,by amphotericin B.

Objective To observe the effect of atropine and N-nitro-L-arginine methyl ester (L-NAME) on the pressure of lower esophageal sphincter (LESP) regulated by electro-acupuncturing (EA) at Zusanli acupoint (He-Sea, st 36) of stomach meridian and explore the neural mechanism of EA. Methods Forty-eight rats were divided into six groups:control group, EA group, atropine group, atropine+EA group, L-NAME group and L-NAME+EA group. LESP was observed and recorded by using three-channel perfusion manometric measurement system. Results LESP increased significantly under or after EA at Zusanli acupoint. Cholinergic M receptor blocker partly abolished the influence of EA on LESP, but EA could restore the decreased pressure of cholinergic M receptor blocked rats. Nitric oxide synthase (NOS) inhibitor increased LESP, and EA could make it higher. Conclusions The main efferent pathway of regulating effect of EA at Zusanli acupoint on LESP is via the chlinergic nerve of vagus, and other mechanism possibly exits.

To describe the clinical,radiological and pathological characteristics of idiopathic pulmonary alveolar proteinosis(I-PAP)and to evaluate the methods of diagnosis and treatment.Three patients were successfully diagnosed and treated in our hospital and the literature on the subject was reviewed.Three patients,two males and one female(mean age 46 years),were diagnosed averagely in 4 months.Two severe patients presented with progressive dyspnea and type I respiratory failure,and one mild patient only with dry cough and hypoxemia.Chest X-ray radiographs all showed perihilar "butterfly" shadow and chest CT scans showed diffused ground-glass opacities(GGO),typically with "map" changes and "crazy paving" patterns.All the patients underwent bronchoscope,branchoalveolar lavage fluid(BALF)had grossly opaque and/or milky appearance and its sediment was periodic acid-Schiff stain positive.Transbronchoscopic lung biopsy(TBLB)specimens were obtained and under light microscopy alveoli and some of the small bronchioles were filled with eosinophilic proteinaceous material with needle-like clefts.By electron microscopy numerous cellular debris and extracellular multilamellated bodies were found.Two severe patients were successfully treated with sequential whole-lung lavage and one required repeated lavages.I-PAP is rare and prone to be misdiagnosed.The radiological features may indicate the diagnosis and examinations of TBLB and BALF can make the accurate diagnosis.Whole-lung lavage is the most effective therapy by now and granulocyte-macrophage colony-stimulating factor(GM-CSF)may be beneficial in some patients.

Objective:To evaluate the efficacy and safety of talc poudrage pleurodesis via semi-rigid medical thoracoscopy in the treatment of malignant pleural effusions,as well as the factors that may influence the outcomes.Methods:A series of 27 patients with malignant pleural effusion underwent medical thoracoscopic talc poudrage pleurodesis between July 2005 and September 2007 in Peking University First Hospital.Results:There were 16 male and 11 female patients in the series,the average age being 65.2 years.All the patients had documented malignant pleural effusions,including 16 cases of adenocarcinoma,6 of malignant mesothelioma,2 of squamous cell carcinoma,1 of lymphoepithelioma-like carcinoma,1of small cell carcinoma and 1 of undifferentiated lung cancer.Thirty days after the procedures,complete successful pleurodesis was achieved in 22 cases,and partial successful in 4 cases.Pleurodesis was not successful in one case.Overall successful rate was 96.3%(26/27).The average duration of thoracic tubing was 6.85 days.Chest pain,fever and an increase in peripheral WBC after the procedure occurred in 19(70.4%,19/27),21(77.8%,21/27),and 12(44.4%,12/27)cases respectively.No respiratory failure occurred.Conclusion:Medical thoracoscopic talc poudrage pleurodesis is a safe and effective method for the treatment of malignant pleural effusion.
