Objective To study the influence of carboxymethyl-chitosan (CM-chitosan) on phenotype and proliferation of chondrocytes stimulated by recombinant human interleukin-1? (rhIL-1?), and explore its mechanism. Methods Chondrocytes were isolated and cultured. 10 ng/ml IL-1? with or without CM-chitosan of varied concentrations were added into the culture medium. After 24 h, changes of proliferative ability of chondrocytes were tested by MTT and flow cytometry. Proteoglycan synthesis was measured by incorporation of Na235SO4 into chondrocytes, nitric oxide (NO) production was detected by Greiss reaction, mRNA expression of typeⅠ、Ⅱcollagens, Aggrecan and inducible NO synthase (iNOS) were examined by semi-quantitative reverse transcription-polymerase chain reaction (RT-PCR). Results CM-chitosan could significantly antagonize IL-1?-induced inhibitory effect on proliferation of chondrocytes, restore proteoglycan synthesis of chondrocytes, decrease NO production of IL-1?-induced chondrocytes, increase the mRNA expression of typeⅡcollagen and Aggrecan, but decrease the expression of typeⅠcollagen and iNOS. The effects of CM-chitosan were in a dose-dependent manner. Conclusion CM-chitosan can maintain the proliferation and phenotype of IL-1?-induced chondrocytes.

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.

Objective To explore the relationship among the sense of coherence,empowerment and self-efficacy in peritoneal dialysis patients.Methods General information,the Sense of Coherence Scale,the Peritoneal Dialysis Empowerent Scale-Short Form and the Self-Efficacy for Managing Chronic Disease Scale were used to investigate a total of 160 peritoneal dialysis patients in a third-class hospital in Tianjin from March to June,2015.Results The mean score of the sense of coherence,empowerment,self-efficacy were (62.01±11.94) points,(4.09±0.68) points and (6.08±2.19) points.Both the sense of coherence and empowerment could positively influence the self-efficacy of peritoneal dialysis patients directly (r=0.429-0.571,P ＜ 0.01),and the sense of coherence could also indirectly influence the self-efficacy through the mediation of empowerment (β decreased from 0.429 to 0.172,P ＜ 0.01),the mediation effect accounted for 60.1％ of the total effect.Conclusions Medical staff should take different actions to improve the sense of coherence and empowerment to improve the self-efficacy of peritoneal dialysis patients.

Designing of natural product-like compounds using natural products as template structures is an important strategy for the discovery of new drugs. Gambogic acid (GA), which is a Garcinia natural product with a unique caged xanthone scaffold, inhibits potent antitumor activity both in vitro and in vivo. This review summarized the researches on the identification of the antitumor pharmacophore of GA, and the design, structural optimization and structure-activity relationship (SAR) of natural product-like caged xanthones based on it.

OBJECTIVETo explore effects of Shenqi preparation,Traditional Chinese Medicine, on anti-fatigue and anti-oxidant functions.

METHODSOne hundred and twenty mice were randomly divided into control group and 3 experimental groups. The high, medium and low-dose of Shenqi preparation were given to the 3 experimental groups respectively, while distilled water to the control group for 15 d. The loaded swimming time, the level of lactate, serum urea nitrogen (SUN), muscle and liver glycogen, liver super-oxide dismutase (SOD), the content of malondialdehyde (MDA), glutathione peroxidase(GSH-Px) were assayed.

RESULTSThe loaded swimming test showed that the exhausted swimming time of 3 experimental groups [(296.0 +/- 25.3)s, (437.0 ĝ 38.9)s, (595.0 +/- 53.9)s respectively] was longer than that of control group [(231.0 +/- 22.5)s, P < 0.05, P < 0.01]. The liver glycogen content of the high and medium-dose experimental groups were higher than that of control group respectively (P < 0.01). The SUN content of each experimental group was less than that of the control group (P < 0.01, P < 0.05). Moreover,in the medium and high dose experimental groups, less accumulation of lactate was found (P < 0.01, P < 0.05), and the content of liver SOD and GSH-Px was higher (P < 0.01, P < 0.05). The content of liver MDA in high-dose experimental group was less than that of the control group (P < 0.05).

CONCLUSIONShenqi preparation, especially the high and medium-dose experimental groups, is able to improve exercise tolerance and has anti-fatigue and anti-oxidant effects in mice.
