Emodin is one of the main active ingredient of Rheum palmatum, and has anti-inflammatory, anti-bacterial, anti-viral and other effects. In recent years, it arouse concern since it has a significant anti-tumor effect with low toxicity. In this paper we mainly report the anti-cancer effects of emodin according to the studies of the past five years, including four parts such as inhibit tumor growth, inhibit migration and invasion, enhance the efficacy of combination therapy, increase chemosensitivity and attenuated side effects. We hope that our work may provide a reference for further study.

OBJECTIVETo investigate the inhibitory effects and mechanism of apigenin (APG) on dominant response of Th2 cells in asthma model of mice.

METHODSThirty-two 6-week-old healthy BALB/c mice, SPF grade, were randomly divided into four groups equally, the normal control group (A), the asthma model group (B), and the two APG groups (C and D) consisted of asthma model mice treated respectively with high-dose (20 mg/kg per day) and low-dose (2 mg/kg per day) APG given by dissolving in 1% dimethyl sulphoxide via intraperitoneal injection. The murine asthma model was established by ovalbumin (OVA) sensitization and provocation. Twenty-four hours after the last airway provocation, acetylcholine (Ach) was administered via caudalis vein for measuring airway resistance by pulmonary function detector; levels of IL- 4 and IL-13 in bronchoalveolar lavage fluid (BALF) and total IgE in serum were determined by enzyme-linked immunosorbent assay (ELISA); total and differential cell counts in BALF were measured by light microscopy; the airway inflammatory infiltration was detected by haematoxylin and eosin (HE) staining; and the signal transducer and activator of transcription 3 (GATA-3) in the lung tissue was determined by Western blot analysis.

RESULTSAs compared with Group A, the airway hyper-reactivity, airway inflammation, cell count and eosinophil percentage in BALF, levels of total serum IgE and BALF IL-4 and IL-13, and GATA-3 protein expression in the lung tissue were significantly increased in Group B (P < 0.05). As compared with Group B, all the above-mentioned indices in Group C and D were lower, showing respective significant difference (P < 0.05), and significant difference was also shown between the two APG treated groups (P < 0.05).

CONCLUSIONAPG could reduce the airway inflammation and hyper-reactivity by down-regulating the expressions of pulmonary GATA-3 and Th, cytokines, which is a potential drug for asthma therapy.

Objective: To observe the clinical efficacy of electroacupuncture (EA) plus Tanbo-plucking the trigger points for scapulohumeral periarthritis (SP). Methods:A total of 80 patients with SP were randomized into an observation group and an EA group by the random number table, with 40 cases in each group. The EA group was treated with EA therapy, and the observation group was treated with EA therapy plus Tanbo-plucking the trigger points. After treatment, the visual analog scale (VAS) and Melle scores of the two groups were compared to evaluate the improvement of shoulder pain and functional activity, and meanwhile the clinical efficacy was observed. Results: After treatment, the total effective rate of the observation group was 95.0％ and the cure and markedly effective rate was 72.5％. The total effective rate of the EA group was 87.5％ and the cure and markedly effective rate was 42.5％. There was no significant difference in the total effective rate between the two groups (P>0.05). The cure and markedly effective rate of the observation group was higher than that of the EA group, and the difference between the two groups was statistically significant (P<0.05). After treatment, the intra-group differences in VAS and Melle scores of both groups were statistically significant (bothP<0.001). The inter-group differences in the changes of the VAS and Melle scores after treatment were statistically significant (bothP<0.001). Conclusion: EA plus Tanbo-plucking the trigger points has a better curative effect than EA therapy alone in the treatment of SP.

Objective To observe the rate-adaptive response of dual sensor pacemakers integrated with activity sensor and minute ventilation sensor.Methods Fifty patients with chronotrepic incompetence were implanted with pacemakers of integrated sensor.The patients with pacemakers implanted were arranged to take upstairs test,downstairs test and tapping test under the monitor of integrated sensor,minute ventilation sensor and activity sensor respectirely.The rate-adaptive responses were tracked down every 15 seconds with remote heart rate monitor.The results were compared with the control group patients with normal sinal chronotropic function(n=15).Results In activity sensor group,pacing rates were significantly higher than the normal control group in downstairs test and tapping test.In minute ventilation sensor group,pacing rates increasement was significantly slower in the beginning of upstairs test.Pacing rates of integrated group were similar to the normal control group in upstairs and downstairs tests.Conclusion The rate-adaptive pacing response of dual sensor integrated with activity sensor and minute ventilation sensor,which is mostly close to the normal chronotropic response,better than that of single sensor.

The hexane extract from marine actinomycetes 124092 showed potent inhibition on B16 cell line by MTT assay. The hexane extract was fractionationed on silica gel column by vacuum liquid chromatography to afford 6 fractions(Fr1~Fr6), and Fr6 showed cytotoxic activity. To determine the bioacitve components of hexane extract, Fr6 was analyzed by GC/MS. The main components were identified as palmitic acid (11.76%), oleic acid (12.16%), linoleic acid (14.77%), and lactobacillic acid (61.31%). It have been reported that palmitic acid, oleic acid, and linoleic acid possess cytotoxic activity on rat ascites tumor cells and linoleic acid have suppressive effect on human lung adenocarcinoma cells.

Objective To explore therapeutic effects and mechanisms of radical scavenger edaravone on experimental cerebral hemorrhage.Methods Two hundred-forty male SD rats were divided randomly into four groups:control group,cerebral hemorrhage group,edaravone treatment group before operation (A) and edaravone treatment group after operation (B).Experimental cerebral hemorrhage model was made according to the method reported by Rosenberg.Water quantity contained in brain and nervous missing sign were observed,meanwhile the levels of superoxide dismutase (SOD) and malondialdehyde (MDA) in brain tissue were measured.Results Compared with cerebral hemorrhage group,nervous missing sign and water quantity contained in brain obviously changed in edaravone treatment group (P

Objective To explore the application and effect of case-based learning(CBL)in vas-cular surgery clinical teaching. Methods Totally 37 resident doctors were randomly divided into 2 groups respectively: CBL teaching group (n=21)and traditional teaching group (n=16). CBL teaching was con-ducted through the following procedures:selecting typical cases-establishing and applying typical case library-autonomous learning-holding regular seminars. Traditional teaching was conducted through the following procedures: basic theory studying-participating in clinical practice-participating in case discus-sion. Evaluation was conducted based on test socre (written test and clinical operational skill test)and res-idents' feedback of teaching effect. Data were statistically described and independent sample t test was performed. Results Theoretical exam score and clinical skill test score were high in CBL group than in traditional group ((thoretical score:(85.53 ±1.75) vs. (79.94 ±2.29);clinical skill test score:(85.10±1.64)vs.(80.31±1.82)). CBL teaching group had advantages in improving learning efficiency, cultivat-ing clinical thinking,promoting mastery and application of knowledge,broadening knowledge, promoting communication and expression ability and improving study enthusiasm ,et al . Conclusion CBL teaching can effectively improve the teaching quality and obtain higher evaluation. Typical case li-brary should be constantly improved and education of vascular surgical basic theory should be strength-ened to promote CBL.

Objective To evaluate the efficacy and safety of topical retinoids in the treatment of acne vulgaris compared with placebo, antibiotics, benzoyl peroxide and sulfur preparation. Methods According to the Cochrane reviewer′s handbook, randomized controlled clinical trials were selected for the systematic review. Results Up to 2002, 15 clinical trials (2,439 patients) that met the inclusion criteria were selected. There were four clinical trials which showed that topical retinoids were more effective than that of placebo (RR=1.87, and 95% CI: 1.13 ~ 3.11),especially for noninflammatory lesions (RR=12.70,and 95% CI : 4.09 ~ 39.40). There were 3 clinical trials which showed that topical retinoids had better efficacy than that of sulfur preparations (RR=1.75, and 95% CI: 1.42 ~ 2.16). For 7 clinical trials of retinoids compared with benzoyl peroxide, and 3 clinical trials of retinoids compared with antibiotics, no conclusion could be drawn. All the clinical trials showed that there were local side effects, including erythema, and scaling etc in the patients using topical retinoids, but no systematic side effects were observed, however, pregnant women had to be very cautious. Conclusions Topical retinoids are effective for acne vulgaris, and has better efficacy than sulfur preparation does, but there is not enough evidence to clarify that the efficacy of topical retinoids is better than that of benzoyl peroxide and antibiotics.
