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.

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.

Objective To observe the lumbosacral plexus nerves by diffusion tensor tractography (DTT) and quantitatively evaluate them by using diffusion tensor imaging (DTI) in healthy volunteers.Methods A total of 60 healthy volunteers (30 males and 30 females) underwent DTI scanning.Mean FA values of the lumbosacral plexus nerves (both sides of lumbar roots L3 to S1,proximal and distal to the lumbar foraminal zone) were quantified.Differences among various segments of lumbar nerve roots were compared with ANOVA test and SNK test.Differences between two sides of the lumbar nerve roots at the same lumbar segment were compared with paired-samples t test.Differences between the proximal and the distal nerve to the the lumbar foraminal zone at the same lumbar segment were compared with paired-samples t test.The lumbosacral plexus nerve was visualized with tractography.Results (1) The lumbosacral plexus nerve was clearly visualized with tractography.(2) Mean FA values of the lumbar nerve roots L3 to S1 were as followings:proximal to the left lumbar foraminal zone 0.202 ± 0.021,0.201 ± 0.026,0.201 ± 0.027,0.191 ±0.016,distal to the left lumbar foraminal zone 0.222 ± 0.034,0.250 ± 0.028,0.203 ± 0.026,0.183 ± 0.020,proximal to the right lumbar foraminal zone 0.200 ± 0.023,0.202 ± 0.023,0.205 ± 0.027,0.191 ±0.017,distal to the right lumbar foraminal zone 0.225 ±0.032,0.247 ±0.027,0.205 ± 0.033,0.183 ±0.021.Mean FA values were significantly different between the proximal nerve to the distal nerve in lumbar nerve roots L3,L4,S1 (t =-9.114-2.366,P ＜ 0.05),but not significantly different in L5 (P ＞ 0.05).Differences were not found between the right and left side nerves at the same lumbar segment (P ＞ 0.05).(3) The whole length of the lumbar roots nerve L3 to S1 can be visualized clearly by using DTT.Conclusions Diffusion tensor imaging and tractography can show and provide quantitative information of human lumbosacral plexus nerves.DTI is a potential tool for the diagnosis of lumbosacral plexus nerve disease.

Objective To explore the relative factors of unstable plaques of carotid atherosclerosis in ischemic eerebrovascular patients.Methods Carotid arteries of a total of 132 cases with ischemic cerebrovascular disease of carotid artery system were inspected by color Doppler ultrasound.The plaques discovered were classified according to ultrasonic appearance and their stability was judged.The relation between hypertension,diabetes,hyperlipemia, smoking and unstable plaques of carotid atheroselerosis was analyzed.Results The most common site of plaque for- mation was the bifurcate of the common carotid artery(56.99%),and the second commonest was carotid artery (23.12%).The incidence of unstable plaques in the patients with smoking,hypertension and diabetes was higher than those without them(P

Objective To observe the therapeutic effect of Qingxiang Concentrated Pill (QCP) on mammary gland hyperplasia (MGH) in rats. Methods Injection of estradiol were given to establish rat models of MGH and QCP was given QCP at the same time. Pathologic changes of mammary gland in rats were observed under light microscope. Changes of breast diameter, mammary gland volume and weight were measured; serum sex hormones levels, SOD activity and MDA content were also estimated. Results QCP could decrease the increased breast diameter, mammary gland volume and weight, reduce the numbers of mammary gland lobules and mammary acini and the diameter of acinar cavities. It could also decrease eatradiol level and MDA content in serum, inhibit the decrease of the coefficient of thymus and increase the serum progesterone level. Conclusion QCP can regulate sex hormone levels, inhibit lipid peroxidation and relieve the pathologic changes of mammary gland in MGH rats.
