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.

Pg.The adherence activity of periodontal pathogens to HA was enhanced by Ss and Av.When cultivated with Sm,the adherence activity of Pg was reduced.Periodontal pathogens had no effect on the adherence activity of Sm and Av,and Ss excepted. Conclusion The adherence activity of periodontal pathogens is lower than that of cariogenic bacteria.Periodontal pathogens can utilize early-attached bacteria to become those predominant bacteria in periodontal ecosystem.

? 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.

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.

Objective To analyze comprehensively the monitoring data of iodized salt in Zhangjiakou city during 2001 to 2009, and to provide basic information for working out control strategies of the iodine deficiency disorders. Methods According to the iodized salt monitoring requirements in National Iodine Deficiency Disorders Monitoring Program of Ministry of Health, a batch of nine salt samples were taken from each processing (wholesale)company of each county or district of the seventeen counties(districts) of Zhangjiakou once a month. Two townships (towns, street offices) were selected by their location of east, south, west and north in each county(district), and a township in central area each year. Four villages(neighborhoods) were selected in each township(town, street office),and eight household salt samples were collected in each village(neighborhood), and quantitatively determined by direct titration of iodine. Results Iodized salt processing(wholesale) : during 2001 to 2009, a total of 1728 batches was monitored, 1689 batch qualified, batch qualification rate 97.74%;15552 salt samples were tested, 15 357 qualified, iodized salt qualification rate 98.75 %. Household salt levels : 5297 villages (neighborhoods) of 1305 townships(towns, street offices) were monitored, 44 316 salt samples were collected, 43 274 qualified, iodized salt qualification rate 98.04%(43 274/44 141 ), iodized salt coverage rate 99.61%(44 141/44 316), qualified iodized salt consumption rate 97.65%(43 274/44 316). Rate of non-iodized salt was 0.40%(260/44 316), and salt median iodine was 30.02 mg/kg. Conclusions The iodized salt quality indicators are within the state-controlled range in Zhangjiakou city for nine years which remaines at relatively stable levels with a smaller range of annual fluctuations.Detection of non-iodized salt over the years has become the main factors affecting the effectiveness of the prevention and control measures.We should increase monitoring,supervision,and universal health education,and prevent the spread of non-iodized salt.

?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.
