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.

The traditional culture methods and the molecular biology methods were used to study the rhizosphere bacterial diversity between fusarium wilt resistant and susceptible watermelon. The results showed that the diversity and the equality of cultured rhizosphere bacteria of resistant watermelon were higher than those of the susceptible watermelon. The reason was that the cultured rhizosphere bacterial di- versity index H′ and 1/D of the resistant watermelon were higher than those of the susceptible watermelon and that the cultured rhizosphere bacterial equality index E of the resistant watermelon were higher than those of the susceptible watermelon. The dominant cultured bacterial genotypes were different between re- sistant and susceptible watermelon. The genotype 1 is the dominant genotype of resistant watermelon, con- sists 51.1%. The genotype 7 is the dominant genotype of susceptible watermelon, consists 58.7%.

BACKGROUND: Absorbable material is a hotspot in orthopedics, which is biodegradable, avoids fixation residues and second surgical trauma compared with the traditional internal fixation.OBJECTIVE: To investigate the clinical efficacy and safety of K-wires, screws and absorbable rods for the internal fixation of Mason II-III radial head fractures.METHODS: Totally 45 patients with Mason Ⅱ-Ⅲ radial head fractures were collected from January 2010 to December 2015 admited in Zhangjiagang First People's Hospital and Zhangjiagang Hospital of Traditional Chinese Medicine, and were then divided into three groups (n=15 per group), followed by implanted with K-wires (group A), screws (group B)and absorbable rods (group C), respectively. The baseline data, operation time, blood loss, healing time, Mayo and Broberg-Morrey scores were compared among groups.RESULTS AND CONCLUSION: (1) There were no significant differences in the baseline data, operation time, blood loss,and healing time among groups (P > 0.05). (2) The Mayo scores in the groups A, B, and C were (88.45±6.22),(92.37±5.60), and (90.82±6.58), respectively; the Broberg-Morrey scores in the groups A, B, and C group were ((90.82±6.83), (93.05±6.54), and (91.68±7.15), respectively; all above scores showed no significant differences among groups (P > 0.05). (4) The total incidence rate of complications in the groups A, B, and C was 20％ (2/15), 13％ (2/15),and 7％ (1/15) respectively, showing no significant difference among groups (P > 0.05). (4) These results indicate that the absorbable rods can obtain satisfactory treatment outcomes for Mason II-III radial head fractures, which is equivalent to the traditional internal fixation. Moreover, it can avoid secondary operation for removing internal fixators and the adverse impact of stress shielding, so it is recommended to be used in clinic.

AIMTo search for flavonoids which possess stronger vasorelaxation action.

METHODSFour quercetin glycosides (1a - d) were synthesized from quercetin in three steps i. e. selective protection of quercetin, condensation with corresponding acetyiglycosyl bromide, and then removal of the protecting group; Six flavone compounds (2a - f) were prepared from phloroglucinol according to the conventional methods; The structures of synthetic compounds were confirmed by IR, 1H NMR, 13C NMR and MS. Vasorelaxation action of ten synthetic quercetin derivatives (or analogues) and four natural flavonoids compounds were examined on the isolated rat thoracic aorta rings; Comparative octanol-water partition coefficients (logP) were measured using a reversed-phase HPLC method.

RESULTSMost of the tested flavonoids showed concentration dependent relaxation effects against PE-induced contractions of rat aortic rings. These compounds had stronger action with the augment of logP values.

CONCLUSIONCompound 3-bromo-5 ,7-dihydroxyflavone (2d) was identified to have the most potent vasodilating action. These compounds exert vasodilating effects that are related to the logP values. A structure-activity relationship of flavonoids was suggested.

OBJECTIVETo assess the efficacy of tendons of minimally invasive therapy (TMIT) combined drug therapy by comparing it with treatment by drug therapy alone on patients with knee osteoarthritis (KOA).

METHODSTotally 60 KOA patients were assigned to the treatment group and the control group according to random digit table, 30 in each group. Patients in the control group took Hydrochloric Acid Glucosamine Capsule and Celecoxib Capsule. Patients in the treatment group additionally received TMIT. The treatment course for all was 4 weeks. Scores for visual analogue scale (VAS) and the Western Ontario and McMaster Universities (WOMAC) Osteoarthritis Index were observed and recorded at week 1 and 4 after treatment by acupotomology mirror.

RESULTSCompared with before treatment, improvement was shown in VAS score, pain and stiffness degrees, activities and functions, and WOMAC scores at week 1 and 4 after treatment in all patients with statistical difference (P < 0.05). Besides, better effect was shown in the treatment group (P < 0.05).

CONCLUSIONSTMIT combined drug therapy could relieve KOA patients' pain, stiffness and joint activities, elevate the overall efficacy. TMIT was easily operated with less injury.

Uridine diphosphate (UDP)-GalNAc : polypeptide N-acetylgalactosaminyltransfemse (ppGalNAcT) catalyzes the initial step in mucin type O-glycosylation in the Golgi apparatus. Here generation and characterization of a polyclonal antibody to human ppGalNAcT2 were described. The subcellular location of ppGalNAeT2 in SGC7901 cell line was investigated using Western blot analysis of fractionated cell extracts and confocal microscopy with this antibody and two Golgi markers: Golgi SNARE (soluble N-ethylmalemide-sensifive factor attachment protein receptor) of 28 ku (GS28) and trans-Golgi network (TGN) 38, markers for the c/s- and trans-Golgi apparatus, respectively. Morphometric analyses indicated that ～60% of the ppGalNAcT2 signal colocalized with the GS28, while～36% of the c/s-Golgi marker colocalized with the ppGalNAeT2. Approximately 34% of the ppGalNAcT2 signal colocalized with the TGN38, whereas 38% of the trans-Golgi marker colocalized with the ppGalNAcT2. The results provide unequivocal evidence for the location ofppGalNAcT2 within the Golgi apparatus, and further highlight the importance of this organelle in the initiation of O-linked glycosylation.
