This article was aimed to study the factors associated with sleep quality of anger-out and anger-in population based on the frequent pattern-tree (FP-Tree) growing algorithm with data mining. The algorithm of structuring frequent model FP-tree and mining frequent itemsets were designed. The database information scanned was recorded by using FP-Tree growing algorithm through state-trees. The frequent itemsets met minimum support required was generated through reducing the search space of project sets and scanning database only one. The data mining of all factors associated with emotional diseases was actualized. The results showed that factors associated with sleep quality of anger-out and anger-in population were disturbance in respiration, cough or snoring, feeling cold, hot or nightmares. The total time for program analysis was 2 seconds. It was concluded that data mining algorithm based on FP-Tree frequent itemsets can effectively realize the useful information receiving from factors associated with emotional diseases.

By using the pharmacophore model of mineralocorticoid receptor antagonists as a starting point, the experiment stud- ies the method of traditional Chinese medicine formula design for anti-hypertensive. Pharmacophore models were generated by 3D-QSAR pharmacophore (Hypogen) program of the DS3.5, based on the training set composed of 33 mineralocorticoid receptor antagonists. The best pharmacophore model consisted of two Hydrogen-bond acceptors, three Hydrophobic and four excluded volumes. Its correlation coefficient of training set and test set, N, and CAI value were 0.9534, 0.6748, 2.878, and 1.119. According to the database screening, 1700 active compounds from 86 source plant were obtained. Because of lacking of available anti-hypertensive medi cation strategy in traditional theory, this article takes advantage of patent retrieval in world traditional medicine patent database, in order to design drug formula. Finally, two formulae was obtained for antihypertensive.

Objective To observe the sub-chronic effects of low doses of arsenic poisoning in rabbits exposed to different periods on some of the serum enzymes and biochemical indicators, and to provide the basis for screening of meaningful hematologic indicators for early diagnosis of arsenic poisoning. Methods Twelve adult rabbits,weighing 2.0 - 3.5 kg, were randomly divided into four groups, 3 in each group, and they were fed with drinking water containing sodium arsenite 0(control),0.01,0.05,0.25 mg/L, respectively. Serum alanine aminotransferase (ALT), aspartate amino transferase (AST), alkaline phosphatase (ALP), γ-glutamyl transacylase (y-GT), total protein(TP), albumin(ALB), globulin(GLP), and ALB/GLP of rabbit were measured by SYSMEX-180 automated biochemistry analyzer after 8 weeks and 12 weeks exposure. Results The results showed that ALT in 0.05 mg/Lgroup of 12 week[(60.00 ± 4.14)U/L]increased significantly compared with the control[(41.50 ± 2.12)U/L, P ＜0.05];AST in 0.25 mg/L group of 8 week and 12 week[(46.50 ± 3.21 ), (52.33 ± 3.81 )U/L]increased significantly compared with the control[(21.33 ± 3.53), (29.50 ± 3.23 )U/L, all P ＜ 0.05];ALP in 0.05 mg/L and 0.25 mg/L group of 12 week [(78.68 ± 4.85 ), ( 103.00 ± 7.83 ) U / L]increased significantly compared with the control [(45.50 ± 5.50)U/L, all P ＜ 0.05];γ-GT in 0.05 mg/L group of 12 week[(19.33 ± 7.50)U/L]increased significantly compared with the contro1[(8.50 ± 3.53)U/L, P＜ 0.05]. TP, ALB, GLP, ALB/GLP of different groups of 8 week and 12 week were not significantly different statistically(F= 0.77,0.02,0.16,3.14 and 0.51,0.29,0.41,0.52, all P ＞ 0.05). Conclusions Zero point zero five mg/L and higher doses of sub-chronic arsenic exposure has some major damage to the liver. Compared with other serum enzymes and the biochemical indexes, serum AST is a early sensitive indicator of liver injury of the arsenic poisoning.

The combined application of statins that inhibit HMG-CoA reductase and fibrates that activate PPAR-α can produce a better lipid-lowering effect than the simple application, but with stronger adverse reactions at the same time. In the treatment of hyperlipidemia, the combined administration of TCMs and HMG-CoA reductase inhibitor in treating hyperlipidemia shows stable efficacy and less adverse reactions, and provides a new option for the combined application of drugs. In this article, the pharmacophore technology was used to search chemical components of TCMs, trace their source herbs, and determine the potential common TCMs that could activate PPAR-α. Because there is no hyperlipidemia-related medication reference in modern TCM classics, to ensure the high safety and efficacy of all selected TCMs, we selected TCMs that are proved to be combined with statins in the World Traditional/Natural Medicine Patent Database, analyzed corresponding drugs in pharmacophore results based on that, and finally obtained common TCMs that can be applied in PPAR-α and combined with statins. Specifically, the pharmacophore model was based on eight receptor-ligand complexes of PPAR-α. The Receptor-Ligand Pharmacophore Generation module in the DS program was used to build the model, optimize with the Screen Library module, and get the best sub-pharmacophore, which consisted of two hydrogen bond acceptor, three hydrophobic groups and 19 excluded volumes, with the identification effectiveness index value N of 2. 82 and the comprehensive evaluation index CAI value of 1. 84. The model was used to screen the TCMD database, hit 5,235 kinds of chemical components and 1 193 natural animals and plants, and finally determine 62 TCMs. Through patent retrieval, we found 38 TCMs; After comparing with the virtual screening results, we finally got seven TCMs.

BACKGROUND:Intermittent negative pressure has been proven to promote the repairing of soft tissue and bone healing, but the effect of negative pressure on the tendon-bone healing after anterior cruciate ligament reconstruction has not been reported.
OBJECTIVE:To research the effect of intermittent negative pressure on tendon-bone healing after anterior cruciate ligament reconstruction and on the biomechanics of tendon grafts.
METHODS:A total of 24 New Zealand white rabbits were randomly selected to establish the models of anterior cruciate ligament reconstruction of autogenous semitendinosus. The hind leg of one side was selected randomly as the negative pressure group, and the joint of the negative pressure side was connected with the micro-negative pressure aspirator through drainage tube and maintained a low-intensity and intermittent negative pressure;the contralateral hind leg was as the control and connected with ordinary drainage tube. Drainage tubes of both sides were removed at the same time after 5 days. At 6 weeks after modeling, the joint fluid was drawn to detect the expression levels of interleukin-1β;femur-ligament-tibia complex was used for tension measurement of tendon graft, and histological observation of tendon-bone interface.
RESULTS AND CONCLUSION:One rabbit had joint infection, and final y 23 rabbits were included in the study. Tension measurement results showed that maximum load for breakage in negative group pressure was significantly greater than that in the control group (P<0.05). Histological observation found that the number of osteoblasts in the negative pressure group was significantly more than that in the control group, and the difference was statistical y significant (P<0.01). Detection of synovial fluid showed that iterleukin-1βcontent in synovial fluid of the negative pressure group was lower than that in the control group, and the difference was statistical y significant (P<0.01). Intermittent negative pressure may play an active role in tendon-bone healing and modeling of tendon graft after anterior cruciate ligament reconstruction.

OBJECTIVETo observe the relationship between the parameters of artery elasticity and coronary artery stenosis in normotensive and hypertensive patients with coronary artery disease (CAD).

METHODSSystemic vascular compliance (SVC), systemic vascular resistance (SVR), brachial artery compliance (BAC) and brachial artery resistance (BAR) were measured by Dynapulse 200M (Pulse Metric, Inc., USA) in 88 hypertensive and 41 normotensive patients with chest pain before coronary artery angiography.

RESULTS(1) The prevalence rate of severe coronary disease (> or = 2 coronary branches) was higher in hypertensives than in normotensives (64.7% vs. 27.1%, P < 0.05); (2) the peripheral artery buffering function was significantly lower in hypertensives than in normotensives [SVC: (0.85 +/- 0.10) ml/mm Hg (1 mm Hg = 0.133 kPa) vs. (1.17 +/- 0.11) ml/mm Hg; BAC: (0.047 +/- 0.011) ml/mm Hg vs. (0.063 +/- 0.010) ml/mm Hg, all P < 0.05]; (3) Lower arterial elasticity was associated with severe coronary artery stenosis.

CONCLUSIONThe non-invasive obtained artery elasticity is associated with the degree of coronary artery stenosis in hypertensive patients with CAD.
