ObjectiveTo evaluate the usefulness of an ultrasonography-based method to examine quadriceps femoris contracting. MethodsThe thickness of bilateral rectus femoris (RF) and vastus intermedius (VI) and the cross-sectional area (CSA) of RF was measured in 10 healthy subjects (n=20) in a relaxed position and 3 isometric contraction states using ultrasonography by two examiners. The date was compared with paired t test. Half of these subjects (n=10) were also measured with MRI at rest. The date was also compared with paired t test. ResultsThere was no significant difference between MRI and static compound ultrasonography, nor between two examiners. There was a significant difference (P<0.05) in thickness of RF and VI between relaxed and isometric contraction conditions. There was no significant difference among isometric contraction conditions. There was no significant difference among measurements of RF-CSA. Conclusionultrasonography shows good validity and reliability in measuring quadriceps shape.

Objectives:To observe the relationship between 2 different ways of nasal tube nutrition supplement patterns and clinical patients'endurance and complication. Methods:Self contrast study was used in 8 cases of old patients supplied with nasal tube nutrition for 4 months(perfusion and dripping pattern 2 months each). Biochemical indices and enteric complications before and after nasal tube nutrition were observed. Results:Slowly dripping supplement pattern greatly decreased the incidence of inhalation pneumonia and other complications related with gastro enteric nutrition supplement,such as diarrhea,bloating,vomits and etc.The nutritional status was obviously improved when the continuous dripping supplement pattern was used. Conclusions:Continuous dripping supplement pattern is better than perfusion supplement pattern.

? AlM: To examine choroidal thickness and its relationship with axial length and spherical equivalent by spectral domain optical coherence tomography ( SD -OCT ) in patients with myopic choroidal neovascularization ( mCNV) .
?METHODS: We prospectively recruited 30 cases of mCNV in Beijing Anzhen Hospital from October 2010 to December 2014. SD-OCT was used to measure choroidal thickness subfoveally and at 1. 5mm superiorly, inferiorly, nasally and temporally ( SFCT, SCT1. 5mm , lCT1. 5mm , NCT1. 5mm , TCT1. 5mm ) . Paired t- test was conducted to assess the difference of spherical equivalent, axial length and choroidal thickness between mCNV group and controls. Logistic regression analysis was performed to evaluate the correlation between spherical equivalent, axial length, choroidal thickness and mCNV.
?RESULTS: The difference of spherical equivalent and axial length between mCNV group and controls was not significant (P>0. 05). lnferior was decreased in mCNV group compared with controls (140. 85±33. 46μm vs 168. 95±45. 36μm). The difference was significant (P=0. 008). Logistic regression demonstrated that decreased choroidal thickness ( lCT1. 5mm ) at inferior location was associated with mCNV (OR=2. 12;95%CI 1. 35~3. 28;P=0. 02).
?CONCLUSlON: The decrease of lCT1. 5MM may be one of the risk factors of mCNV.

Objective To study the clinical characteristics and treatment of primary nasal B-cell lymphoma (PNBCL). Methods A retrospective analysis was performed based on the clinical records of 18 PNBCL cases who were treated from January 2009 to June 2015. The clinical manifestations, imaging features, diagnosis approaches and treatment of them were analyzed. Results The main symptoms were nasal obstruction and rhinorrhea. Of all patients, 15 cases were in Ann Arbor stageⅠE-ⅡE, and 3 cases were in Ann Arbor stageⅢE-Ⅳ. The median age was 51 years (12-76 years). The ratio of men to women was 11:7. Only 1 patient had B symptoms. Elevated LDH levels were observed in 4 patients. 13 patients were diffuse large B-cell lymphoma(DLBCL), 3 patients were mantle cell lymphoma, and 2 patients were Burkitt lymphoma. CT examination showed the abnormal nasal soft tissue shadow, with unilateral location and light to moderate enhancement. 14 patients received combination chemotherapy only, and 3 patients received chemotherapy and radiotherapy. Total effective rate was 82.3 % (14/17). At the time of last follow-up, 5 patients died, and the 3-year OS rate was 54.5%(6/11). Conclusions Most PNBCL patients are in Ann Arbor stageⅠE-ⅡE and B symptoms are rare, and the most common pathological types is DLBCL. The treatment for PNBCL is chemotherapy, radiotherapy can assist, but the prognosis is poor, and innovative chemotherapy regimens are necessary.

?AIM:To evaluate the incidence and clinical properties of dry eye after phacoemulsification in age-related cataract patients.?METHODS: Samples were collected from 145 age -related cataract patients (145 eyes).Dry eye was analyzed at 0, 7, 30, 90 and 180d after phacoemulsification by 1 ) Ocular Surface Disease Index questionnaire ( OSDI ) , 2 ) tear meniscus height ( TMH ) , 3 ) corneal fluorescein staining, 4) tear film break-up time (BUT), 5)SchirmerⅠtest( SⅠt) .?RESULTS:The symptoms and signs of dry eye, such as narrowing of TMH, shorting of BUT, decreasing of SⅠt, cornea staining by fluorescein, occurred as early as 7d post-phacoemulsification and were measured by OSDI questionnaire and 4 additional clinical tests.Over the six-month observation the severity of dry eye peaked at 30d and then gradually relieved.? CONCLUSION: The severity of dry eye after phacoemulsification peaked at 30d and gradually improved over time. Considering the characteristics of ocular surface for aged people ophthalmologists should pay more concern on evaluating the occurring of dry eye after phacoemulsification so as to improve the life quality of these people.
