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.

Urine cell-free DNA (ucfDNA) contains DNA fragments released from the lysis of cells in the urinary system, and circulating cell-free DNA (ccfDNA) can also enter the urine after glomerular filtration, and the mutation information carried by tumor DNA contained in ucfDNA and ccfDNA is consistent. Therefore, as a biomarker for molecular diagnosis of urological and non-urinary tumors, ucfDNA, has become a research hotspot in the field of liquid biopsy in recent years. UcfDNA has potential application value in individualized treatment, early diagnosis, dynamic monitoring of therapeutic efficacy, and prognosis assessment, etc. However, in order to realize the clinical application of urine ucfDNA, the extraction and accurate detection of ucfDNA still need to be solved.

OBJECTIVE: To evaluate pharmacokinetics (PK), efficacy, and safety of atezolizumab (anti-PD-L1) in high interest cancers in China, including esophageal cancer (EC), gastric cancer (GC), hepatocellular carcinoma (HCC), nasopharyngeal cancer (NPC), and non-small cell lung can-cer (NSCLC). METHODS: This phase I, open-label study was conducted at 6 Chinese sites from August 4, 2016 to April 15, 2019. The patients were ≥18 years old with a histologically documented incurable or metastatic solid tumor that was advanced or recurrent and had progressed since the last anti-tumor the-rapy. The PK phase characterized PK and safety of atezolizumab following multiple-dose administration when atezolizumab was administered as a single agent. The extension phase studied safety and efficacy of atezolizumab, as monotherapy (EC, GC, HCC, NPC) and with chemotherapy (NSCLC). RESULTS: This study enrolled 120 patients (PK phase: n=20; extension phase: n=20/cohort). Fourty-two patients (42.0%) were PD-L1 positive in atezolizumab monotherapy group (100 patients), of the 9 patients (9.0%) with microsatellite instability-high (MSI-H) tumors. Atezolizumab clearance was 0.219 L/d, and steady state was reached after 6 to 9 weeks (2-3 cycles) of repeated dosing. Objective response rates (ORRs) in EC, GC, HCC, NPC, and NSCLC were 10.0%, 15.0%, 10.0%, 5.0%, and 40.0%, respectively. In the patients with PD-L1 positive tumors, ORR was 11.9% with atezolizumab and 46.2% with atezolizumab plus gemcitabine and cisplatin. Two GC patients achieved durable response after pseudo-progression. The most common treatment-related adverse events in the atezolizumab monotherapy group were fatigue, anemia, fever, and decreased white blood cell count. The most common treatment-related adverse events in the combination group were anemia, decreased white blood cell count, and decreased appetite. No new safety signals were identified. CONCLUSION Atezolizumab's PK, efficacy, and safety were similar in Chinese patients vs. global patients in previous studies.

ObjectiveLymphatic epithelial cells (LECs) are important links involved in lymphatic metastasis in the microenvironment of cholangiocarcinoma. This study aims to detect the modulation of inflammatory factors and chemokines secreted by LECs after stimulation of cholangiocarcinoma cells, and observe the effects of highly expressed factors on lymphangiogenesis.MethodsThe culture medium of cholangiocarcinoma (RBE, HCCC9810), LECs stimulated by cholangiocarcinoma cell culture medium (CCM), and normal LECs were prepared. Inflammatory factors and chemokines in the culture medium were detected using protein chip. The experiments are divided into the following groups, including a blank control group, CCM group, CCM coupled with Anti-ENA-78 group, Anti-ENA-78 group, ENA-78 group, ENA-78 coupled with SB2252002, and SB225002 group. The relationship between the content of factor and time was investigated using ELISA, while the relation between target factors and lymphangiogenesis obtained by cell proliferation and tubule formation assay.ResultsWe found ENA-78, IP-10, GCP-2, MCP-2, MCP-3, MIP-3a, HCC-1, and Lymphotactin expression increased in LECs supernatant after CCM stimulation. However, I-TAC, MIP-1d, IL-10, MIG, PDGF-BB, and CXCL16 factors showed down-regulation. The secretion of ENA-78 in CCM was relatively low. By ELISA, we found that the ENA-78 protein in RBE-LECs and HCCC9810-LECs gradually increased over time, and reached the plateau phase at the point of 48h. The lymphatic tube forming ability of LECs cultured in CCM was significantly increased compared with that of the control group, and this ability could be partially weakened by ENA-78 neutralizing antibodies. In the exogenous ENA-78 protein group, the lymphatic tube formation ability was as well significantly increased compared with that in the control group, and this ability could be effectively blocked by the IL-8B inhibitor.ConclusionThe increased secretion ENA-78 of lymphatic epithelial cells induced by cholangiocarcinoma may play a role in promoting lymphangiogenesis through the IL-8B receptor.

A new type of L. Bulgaricus microcapsule was prepared to improve stability and resistance of L.Bulgaricus probiotics in harsh environments. An optimal method of preparation of L. Bulgaricus microcapsule is as follow. L. Bulgaricus was mixed with 3% alginate solution. The concentration of bacterial suspension was 1×10⁹ cfu·mL^-1. The mixture was microencapsulated by extrusion into 2% CaCl₂ solution with a dispensing equipment. After 30 min solidification, the gel beads were lyophilized to obtain L.Bulgaricus microcapsules. The microencapsulation technology was aimed to improve the stability and survival rate of L. Bulgaricus. The microcapsule was spherical with uniform particle size and intact structure. The tolerance of acid, high temperature, high humidity and the long-term stability of freeze-dried powder and microcapsule were evaluated. The results indicated that microencapsulation technic could greatly improve stability and resistance of L. Bulgaricus probiotics in harsh environments.

OBJECTIVETo analyze the complications of percutaneous kyphoplasty except bone leakge for the treatment of osteoporotic thoracolumbar vertebral compression fractures.

METHODSFrom October 2008 to October 2012,178 patients with 224 osteoporotic vertebral compression fractures were treated with percutaneous kyphoplasty under local anethsia. There were 72 males and 106 females,ranging in age from 58 to 92 years old,with an average of 75.3 years,including 93 thoracic vertebrae and 131 lumbar vertebrae. The complications except bone cement leakage were analyzed during operation and after operation.

RESULTSAll operations were successful and all patients were followed up from 12 to 60 months with an average of 26.2 months. No death was found. Bone cement leakage occurred in 27 cases, about 15.1% in 178 cases; and complications except bone cement leakage occurred in 15 cases. There was 1 case with cardiac arrest,was completely recovery by cardiopulmonary resuscitation (CPR) immediately; and 1 case with temporary absence of breathing,was recovery after treatment. There were 3 cases with fall of blood pressure and slower of heart rate; 1 case with intestinal obstruction; 2 cases with local hematoma and 1 case with intercostal neuralgia. Vertebral body fractures of 2 cases were split by bone cement and the fractures of adjacent body occurred in 4 cases.

CONCLUSIONIt's uncommon complication except bone cement leakge in treatment of osteoporotic thoracolumbar vertebral compression fractures with percutaneous kyphoplasty. The complication of cardiopulmonary system is a high risk in surgery; and cytotoxicity of bone cement,nervous reflex,fat embolism and alteration of intravertebral pressure may be main reasons.

Objective To investigate the influencing factors of diagnostic time in adult moyamoya disease (MMD) and provide evidence for its early diagnosis. Methods The clinical data of 65 consecutive patients, admitted to our hopspital from August 2008 to December 2009, were retrospectively analyzed. Logistic regression nalysis was employed to confirm the relevant factors of diagnostic time. Results The 65 patients with early diagnosis and late diagnosis were 41 (63.1%) and 24 (36.9%), respectively. The percentage of patients firstly visiting a hospital with the third grade, patients with high education and high income, and patients having initial hemorrhage of the early diagnosis group was significantly higher than that in those of late diagnosis group (P<0.05). Through a logistic regression analysis, the grade of initial hospital, the level of education, initial symptom and economic level were significantly associated with the early diagnosis, and the patients having initial hemorrhage and firstly visiting a hospital with higher grade were diagnosed earlier (OR=3.401, 95%CI 1.301-8.892, P=0.013;OR=26.351, 95%CI 4.953-140.193, P=0.000). Conclusion Patients with MMD having initial hemorrhage and firstly visiting a hospital with the third grade can be early diagnosed.
