OBJECTIVE:To provide reference for improving medication compliance and treatment effect of the hypertension pa-tients. METHODS:3 community health center in Tianjin Hebei district were randomly selected,and 100 hypertension patients who were randomly selected from each community health center in Jan. 2015 to Dec. 2015 in Tianjin investigated by questionnaire sur-vey to explore the basic situation,drug utilization,medication compliance,and the influential factors of medication compliance were analyzed with Logistic regression analysis. RESULTS:Totally 300 questionnaires were sent out,and 300 were recycled with effective recovery of 100%. In the investigation,taking 2 drugs accounted for the majority of hypertension patients (51.67%);CCB and ACEI were most commonly used in the treatment of patients with hypertension(accounting for 59.33% and 30.67%,re-spectively);the proportion of good medication compliance was 34.00%;the community health center,drug type,economy,time to take medicine,hypertension knowledge were main factors for influencing the medication compliance of patients. CONCLU-SIONS:The treatment of hypertension patients should take some intervention measures,especially taking necessary measures for the main factors that influence the medication compliance of the patients to improve medication compliance of patients and treat-ment effect.

BACKGROUND:Traditional distal femoral fixation plate screw breakage is relatively common. Designing good anatomical and attached fixation system is the key for clinical application.
OBJECTIVE:To perform finite element analysis in two states of motion of the minimal y invasive distal femoral fixation system, compare stress distribution of different parts in the same fixed way, different fixed methods and the same fixed parts of different motion states.
METHODS:Imaging data of a 34-year-old male patient weighing 68 kg with 33-C1 type fracture of distal femur were selected. CT data were input into Mimics 16.0 for reconstruction. PRO-E software was used to establish minimal y invasive internal fixation system with distal femoral locking plate. Data were introduced into reconstructed models of distal femur fracture in Mimics for grid division. Data were introduced into Ansys products 11.0 to construct finite element model, fix the surface of distal femur, and loaded 340 N on greater trochanter of femur. Stress distribution of each plate, screw hole and screw tail was analyzed in each group. Stress at the same region was compared in flexion and extension movement states.
RESULTS AND CONCLUSION:(1) Finite element models of anatomic locking plate for distal femur fracture fixation were successful y established, total y 43 536 units, 41 256 nodes. (2) With the steel segment gradual y down (S1-S5), the stress gradual y increased. A1-A5 with the increase in the number of screws, the stress gradual y increased, but A6 suddenly decreased. (3) According to the cloud atlas of stress, these were wel distributed except A1. From distal end to extremity of screw, the stress of screws increased. Among corresponding segments, significant differences in stress around the nail holes and steel segment stress were detected. Moreover, the steel stress was greater than the stress of corresponding segment of screw hole. (4) Results suggest that using anatomical locking plate and minimal y invasive internal fixation system for distal femur fracture in a variety of fixed modes and moving conditions, the stress of each part is less than the yield strength of the titanium al oy screw, so the fixed system wil not produce instantaneous deformation or fracture.

0.05) but CO, SV and CVP increased and SVR decreased significantly after AHH in both groups as compared with those before AHH. pH, Lac and COP did not change significantly after AHH. There was no significant difference in the volume of solution infused, blood loss, CO, SV, CVP and SVR between the two groups. Conclusion Age is not a primary factor negating the use of AHH. Under combined general-epidural anesthesia AHH with 6% hydroxyethyl starch (15 ml?kg-1 ) can be well tolerated by the elderly patients without cardiac and pulmonary disease.

35 % and the intraoperative blood loss was expected to be 800-1 600 ml. The operations were performed under combined general-epidural anesthesia. General anesthesia was induced with fentanyl 2-4 ?g?kg-1 , thiopentone 5 mg?kg-1 and succinylcholine 1.5mg? kg-1 and maintained with isoflurane inhalation and intermittent iv boluses of vecuronium. Epidural anesthesia was performed at T5-6 (thoracic surgery), T10-11 (upper abdominal surgery) or L3-4 (lower abdominal surgery) . A mixture of 0.1% lidocaine +0.2% dicaine was used for epidural block during operation. The patients were randomly divided into 2 groups: (1) ANIH group ( n = 18) and (2) AHH group ( n = 20) . Blood volume (BV) was calculated according to following formula: BV (ml) (male) = Height (cm)? 28.5 + Body weight (kg) ? 31.6 - 2 820,BV(ml) (female) = Height(cm)? 16.25 + Body weight (kg) ? 38.46 - 1 369. 1 000-1 200 ml of 6% HES (200/0.5) and 500 ml of lactated Ringer's solution (about 25%-30% of BV) were infused at a rate of 50ml?min-1 when induction of anesthesia was started in both groups. In group I (ANIH) 400-600 ml of blood (about 10%-15% of BV) was removed through radial artery before induction of anesthesia. The removed blood was reinfused at the end of surgery. Vital signs (BP,HR,CVP and ST-T changes) , Hct, oncotic pressure and arterial blood lactate concentration were monitored during operation. Results The vital signs were fairly stable during perioperative period in both groups. Transient hypotension developed in 16.7% (3/8 in group Ⅰ ) and 15.0% (3/20 in group Ⅱ ) of patients during induction of anesthesia. CVP was significantly elevated in both groups but the increase in CVP was significantly higher in group Ⅱthan that in group Ⅰ . In group Ⅰ (AN1H) moderate hemodilution was achieved (Hct = 29.9% 2.9%) while in group Ⅱ (AHH) only mild hemodilution was achieved (Hct = 32.9% ?2.9%) .Hct was significantly higher in group Ⅰ(31.5% ?5.1%) than that in group Ⅱ (27.7% ?3.6%) at the end of surgery. Blood loss was comparable between the two groups, and oncotic pressure and blood lactate level were within normal range in both groups. Conclusion ANIH is more effective and safer than AHH without obvious adverse effects, and can avoid exceedingly high CVP commonly seen in AHH. ANIH is a hemodilution technique of choice in the elderly patients.

Objective To investigate the effect of isoflurane administered before ischemia on polymorphonuclear neutrophil (PMN) infiltration and expression of adhesion molecules in the lung injured by ischemia-reperfusion.Methods One-hundred and twenty male SD rats weighing 250-350 g were randomly divided into 4 groups ( n = 30 each) :Ⅰ sham operation group (S) ;Ⅱ I/R group in which hilum of left lung was clamped for 45 min and then undamped for reperfusion; Ⅲ Iso + I/R in which 1 MAC isoflurane was inhaled for 30 min before ischemia and Ⅳ Iso + S in which 1 MAC isoflurane was inhaled for 30 min without I/R. The animals were anesthetized with intraperitoneal pentobarbital 50 mg?kg-1 then tracheostomized and mechanically ventilated with 100% O2(VT= 10-15 ml?kg-1) . PaCO2 was maintained at 35-45 mm Hg. Right jugular vein and left carotid artery were cannulated for BP monitoring, blood sampling and fluid and drug administration. Anesthesia was maintained with ketamine 10 mg?kg-1?h-1 and vecuronium 0.1 mg?kg-1?h-1. 1 MAC isoflurane (1.38% in rats) was inhaled for 30 min before hilum of left lung was clamped with an atraumatic clamp. Left lung ischemia was maintained for 45 min then the left lung was released for reperfusion. MAP was monitored and blood gases were analyzed during experiment. The animals were killed at the end of 45 minute ischemia and at 30, 60 and 120 min reperfusion and left lung was removed for: (1) determination of W/D lung weight ratio, myeloperoxidase (MPO) activity and expression of ICAM-1 mRNA; (2) light and electron microscopic examination; (3) broncho-alveolar lavage (BAL). BAL fluid (BALF) was collected and the number of cells, percentage of PMN and total protein concentration in BALF and the expression of CD18 on PMN surface were determined. Results The W/D lung weight ratio, MPO activity and expression of ICAM-1 mRNA in the lung tissue, the percentage of PMN and TP concentration in BALF and the expression of CD18 on PMN surface were all significantly increased during reperfusion in I/R group but isoflurane pretreatment significantly attenuated the I/R induced increases. Histological examination showed that the I/R induced lung injury was also ameliorated by isoflurane pretreatment. Conclusion Inhalation of isoflurane before ischemia could protect the lungs against I/R injury by inhibiting the PMN infiltration and expression of ICAM-1 mRNA and CD-18.

To increase efficiency of automated leucocyte pattern recognition using lower feature dimensions, a novel inter-class distinctive feature selection method for chromatic leucocyte images was proposed based on attribute hierarchical relationship. According to the attribute constraints in formal concept analysis, we established a knowledge representation and discovery method based on the hierarchical optimal diagram by defining attribute value and visual representation of optimized hierarchical relationship. It was applied to human peripheral blood leucocytes classification and 12 distinctive attributes were simplified from 60 inter-class attributes, which contributes significantly to reduced feature dimensions and efficient inter-class feature classification. Compared with the classical experimental data, the inter-class distinctive feature selection method based on hierarchical optimal diagram was proved to be usable and effective for six leucocyte pattern recognition.
