Four key attributes,position,rate,shape and force,are programs of pulse tracing put forward by ZHOU Xue-hai,a medical practitioner in late Qing dynasty.The essences of four key attributes are'images'of di erent levels.There are complex relationships between pulse tracing and position,rate,shape and force attributes,which include not only subordinate relationship and static-dynamic relationship between four attributes but double relationship between four attributes and pulse tracing.

? AlM: To investigate the therapeutic effects of Pranoprofen on tear dynamic abnormity induced by conjunctivochalasis ( CCh) .
?METHODS: Seventy cases ( 70 eyes ) whose the main symptoms was epiphora induced by CCh were divided into II, Ⅲ and Ⅳ in 3 groups according to Zhang’s grading standards, meanwhile, all the patients were treated with the eye drops of Pranoprofen for 2wk. After that, the curative effect of each group was analyzed before and after treatments according to the symptoms, dye disappearance test, bitter taste test and tear break-up time.
?RESULTS: After 2wk treatment of Pranoprofen, the symptom of patients at grade I and II improved obviously grade Ⅲ improved more, grade Ⅳ did little. The positive rate of dye disappearance was the highest in grade II, the second in grade Ⅲ, and the third in gradeⅣ. There was significant difference among the 3 groups (P<0. 05). The time of bitter taste test was shortened (P<0. 05) and the tear break-up time was prolonged (P<0. 05) in grade II after treatment, however, the time of those in gradeⅢandⅣhad not changed than before ( P>0. 05).
?CONCLUSlON: Pranoprofen has good effects on tear dynamic abnormity induced by grade II of cch.

Objective To explore the operation timing and technique selection of floating knee injury in children.Methods According to Letts types,36 cases were divided into 5 types.The function outcome in every group was compared by Karlstrorm criterion according operation timing or technique selection respectively.Results Thirty-six cases were followed up for an average of 25 months(19 to 84 months).The rate of excellent and good results accounted for 94.12%(16/17) in one stage operation,78.95%(15/19)in stages,60%(6/10)in 2 stages,respectively.Conclusions It may be recommended to treat children with floating knee injury with open reduction intenal fixation or external fixation.The best operation time shall be urgent treatment of both femur and tibia fracture.

Objective To investigate the level of serum free fatty acid (FFA )after improving the life style in patients with coronary heart disease complicated metabolic syndrome and the effect of therapeutic life style on traditional risk factors of coronary artery disease.Methods A total of 395 patients with coronary heart disease complicated metabolic syndrome were recruited.Pa-tients were divided into intervention group (group A,conventional drug therapy+ intensive life style intervention,n=97)and non-intervention group (group B,conventional drug therapy,n=38)according to the scores of life style.Serum free fatty acid (FFA) was determined by ELASA.The scores of life style was obtained bylife style questionnaire.Results (1)The serum FFA of pa-tients with coronary heart disease complicated metabolic syndrome were positively related to waist circumference and waist-high-ra-tio.(2)Waist circumference,BMI and FFA of group A were significantly lower than those in group B after therapeutic life style in-tervention(P <0.05).(3)Compared with the baseline,the constitution index and FFA in group A were significantly lower after 6-months therapeutic life style intervention(P <0.05).Conclusion Therapeutic life style can reduce the level of FFA and constitution index of the patients with coronary heart disease complicated metabolic syndrome.

Objective To assess the application of contrast-enhanced ultrasound (CEUS) in evaluation of the renal cortical and medullary perfusion changes before and after acute renal failure (ARF) in rabbits. Methods Rabbit ARF models were established with intramuscular 50% glycerin (12-15 ml/kg) injection into rabbits' thighs. One day before and after ARF models establishment, CEUS was performed on each rabbit. The renal perfusion time-intensity curve (TIC) was analyzed, including parameters like AT (arrival time), TTP (time to peak intensity), A (amplitude of peak intensity), AUC (area under the curve), β (slope rate of TIC) of renal cortex and medulla. Results The value of A and β before model establishment was (17.36±13.73) dB and (5.38±2.08) dB/s, respectively, both was significantly higher than those after glycerin injection ([6.59±4.25] dB and [1.58±1.41] dB/s, respectively) (P<0.05). The value of TTP and AUC before model establishment was (2.46±1.76) s and (329.31±171.70) dBs, both was significantly lower than those after injection ([5.93±4.80] s and [722.28±354.14] dBs, respectively) (P<0.05). No significant difference was found in AT of renal cortex and AT, A, TTP, AUC, β of renal medulla, nor in SCr or BUN. Conclusion CEUS can display the changes of perfusion image of the renal cortex of the ARF earlier than SCr and BUN.
