OBJECTIVE To investigate the clinical characteristics,nasal endoscope and imaging findings, misdiagnosis and treatment results of sphenoid sinus malignant tumor.METHODS The clinical data of 9 cases with sphenoid sinus malignant tumor were summarized and analyzed.Headache was found in 8 patients, ophthalmic symptoms in 3 patients,nasal bleeding and obstruction in 3 patients,and cranial nerve palsy in 2 patients.They were often misdiagnosed as sphenoid sinusitis and nasopharyngeal carcinoma.RESULTS Only 1 patient with papillary carcinoma was cured for 6 years.One patient with neuroendocrine carcinoma was alive for 3 years after treatment.Four patients died at 2 to 3 years.Two patients were alive at 1 year after operation. One patient was lost to follow up.CONCLUSION Sphenoid sinus tumor had no characteristic symptoms in early stage.It is easy to misdiagnose and delay diagnosis. Patients with headache,visual symptoms and nasal bleeding should take nasal endoscopy,CT scan and MRI examination at early stage.

Electrophysiology examination is an important technique in studying amblyopia, which mainly includes electrooculography( EOG), electroretinography ( ERG), visual evoked potential( VEP). This study does not only summarizes the definition, the mechanisms and the meaning of these indexes in the relevant research progress in recent years, but also makes a comment on the controversies among the relevant research conclusions.

The normal growth of blood vessels is the result of dynamic balance of angiogenic factor and inhibitory factor in vascular tissue.However, when the balance is broken, the growth of new blood vessels will be induced.Endogenous angiogenesis inhibitory factor, is a group of negative feedback molecules produced by the body itself that inhibit angiogenesis.Its function of inhibiting angiogenesis is mainly realized by promoting the binding of angiogenic factor to its receptor, or its downstream angiogenesis signal, or promoting vascular endothelial apoptosis.The study of angiogenesis inhibitory factor has potential clinical significance for the prevention and treatment of retinal neovascularization.Recent studies on retinal neovascularization inhibitory factor are reviewed in this paper.

Drug safety has always been a global focus. Discovery and accurate information acquisition of adverse drug reaction have been the most crucial concern. Terminology of adverse drug reaction makes adverse reaction medical report meaningful, standardized and accurate. This paper discussed the domestic use of the terminology WHOART and MedDRA in terms of content, structure, and application situation. It also analysed the differences between the two terminologies and discusses the future trend of application in our country

Objective To analyze the risk factors of laryngeal carcinoma.Methods The data of laryngeal carcinoma inpatients of our hospital from October 2005 to November 2007 were reviewed retrospectively by a case control analysis.Results The males who have smoking addiction,alcohol consumption,family history of malignant tumor and have more risks to suffer from laryngeal carcinoma.For The family history,OR is 2.01 in the single factor analysis,and in the multivariate analysis the OR is 2.27.Conclusion Gender,smoking,alcohol and family history of malignant tumor have great effect on the risk of laryngeal carcinoma.Family history of malignant tumor is an independent risk factor.

OBJECTIVETo investigate the characteristic changes in the infrared thermogram of chronic prostatitis (CP) patients and find some evidence for the auxiliary diagnosis and therapeutic evaluation of the disease.

METHODSFifty CP patients and 20 healthy male volunteers were included in this clinical trial. The infrared thermograms of the subjects were compared between the two groups for characteristic changes. The values obtained were used for the auxiliary diagnosis and therapeutic evaluation of the disease.

RESULTSCompared with the healthy males in the same age group, the CP patients showed extremely significant abnormal changes in the average temperature value in the hypogastrium (H), pubis (P), scrotum (S), and groin (G) (P < 0.01). The average H temperature value of the CP patients was correlated negatively with the CP symptom index (CPSI) (P < 0.01, Pearsons correlation coefficient = -0.519), while the S temperature positively with CPSI (P < 0.01, Pearsons correlation coefficient = 0.446). In addition to the H value, the P, S, and G values were all correlated in different degrees with CPSI (P < 0.01), which the S value exhibited the most significantly negative correlation (Pearson's correlation coefficient = -0.898).

CONCLUSIONThere are some characteristic changes in the hypogastrium temperature of CP patients in the infrared thermogram, which has a potential application value for the auxiliary diagnosis, symptom assessment, and therapeutic evaluation of CP.

Objective To summarize surgical results of secondary tunnel-like subaortic stenosis( STSS) after congenital heart disease( CHD) operations, analyze the pathogenesis of STSS, evaluate the operative effect and prognosis.Methods We analyzed clinical data of 25 patients who underwent surgical repair for STSS in Fuwai Hospital from January 2009 to December 2015.There were 17 males and 8 females.CHD types included double outlet right ventricle, ventricular septal defect and par-tial atrioventricular septal defect, et al.The median age of the patients when they received their first CHD operations was 1 year (1 month to 42 years).The median age of the patients when they received TSS repair was 5 years and 8 months(2 years and 10 months to 48 years) .The surgical types contained modified Konno procedure , Konno procedure, resection of the conal sep-tum, resection of fibromuscular ridge and myectomy, removal and reconstruction of the intraventricular baffle.Results All the patients successfully received their TSS repair .There was no surgical death in this study .The preoperative gradient of aortic valve pressure was 81(43 to 159)mmHg(1 mmHg=0.133 kPa), and the postoperative gradient was 8.2(4.0 to 46.2) mm-Hg.Ⅲ degree atrioventricular block was occurred in 2 patients after operation and both 2 patients needed to set permanent pacemaker.All the patients were followed up after discharge for a median duration of 2 years( 4 months to 6 years) .During follow-up, none of the patients had any clinical symptom or subaortic restenosis , and there was no late death .Conclusion The pathogenesis of STSS is perhaps related to turbulent flow and shear stress to the left ventricular outflow tract , resulting in the proliferation of fibromuscular marterials and stenosis in the left ventricular outflow tract .The modified Konno procedure and resection of the conal septum are safe and effective.

Objective To study blood lipids levels of patients with ischemic cerebral vascular disease (ICVD).Methods The blood lipids levels were measured in 2886 subjects with ICVD enrolled from 1991 to 2004,in which 1430 subjects from 2000 to 2004 were classified into a sub-group;400 healthy persons receiving physical examination were enrolled as controls.Results The blood TC,TG and LDL-C levels were significantly higher in the sub-group than those in the control group.Both in males and females, the morbidity of abnormal blood lipid metabolism and blood lipids level gradually increased with the age and the lapse of decades.Total cholesterol level of male younger than fifty,averaging (4.43?0.51) mmol/L, increased to (4.96?0.85) mmol/L after fifty years old.The same thing happened to females,from (4.30?0.49) mmol/L to (5.01?0.90) mmol/L.TG and LDL-C increased in patients older than fifty compared with those younger than fifty.In the groups above 50 years old,the blood lipids levels of females were significantly higher than those of males.The morbidity of abnormal blood lipid metabolism of male increased from 24.5% in (1991 to 1994) to 38.1% (2001 to 2004) and of female from 22.3% (1991 to 1994) to 38.5% (2001 to 2004).Conclusions Abnormal blood lipid in Foshan is one of the most important reasons to ICVD.

There are some problems with this course of medical laboratory special English, such as reference materials, teaching contents, teaching ways, the evaluation forms, etc. The department of medical laboratory of North Sichuan Medical College did exploratory reforms including 1+n teaching mode (one major teacher and several co-operational teachers in discussion section), Flipped classroom and interactive teaching, new formative assessment forms (usual performance combing final shows grade), etc. They used innovative teaching way with the purpose of establishing new teaching way , cultivating abilities of au-tonomous learning and comprehensive application.

Class Ⅱa bacteriocins can be considered as the major subgroup of bacteriocins from lactic acid bacteria, not only because of their large number, but also because of their activities and potential applications. They have first attracted particular attention as listericidal compounds and are now believed to be the next in line if more bacteriocins are to be approved in the future. The present review attempts to provide an insight into general knowledge available for class Ⅱa bacteriocins and discuss common features and recent findings concerning these substances.
