OBJECTIVETo study the antalgic and antiphlogistic functions and mechanism of ronggudingtong (RGDT) plaster (traditional Chinese medicine).

METHODSThe painful models were established with hot plate test or acetic acid writhing and the inflammatory models were established with daubing dimethylbenzene on auricle or injecting formaldehyde in toe or synovial envelope to study the antalgic and antiphlogistic functions of RGDT Plaster. The total protein and leukotriene B4(LTB4) in inflammatory exudate were detected to investigate the antalgic and antiphlogistic mechanism of RGDT plaster. The mice were randomly divided into different groups (n = 11), on the basis of drug using, the indexes of pain threshold, swelling degree were observed. Sixty-six mice were used to establish gasbag synovitis model and randomly divided into normal control group,model control group, positive control group (Voltaren gel 0.8 mg/d)and low/medium/high dosage RGDT plaster treating groups(30 mg/d, 60 mg/d, 120 mg/d).

RESULTS30 mg/d, 60 mg/d,120 mg/d RGDT plaster could upgrade the pain thresholds, remit auricular and foot swelling (P < 0.05, P < 0.01), and degrade total protein and LTB4 in inflammatory exudates (P < 0.05, P < 0.01).

CONCLUSIONRGDT plaster has some antalgic and antiphlogistic functions, and one of the mechanisms is depressing synthesis of LTB4.

Objective: To observe the clinical efficacy difference in treating irritable bowel syndrome-diarrhea (IBS-D) of liver-qi stagnation and spleen-deficiency pattern with different treatment protocols, and the effects on serum levels of 5-hydroxytryptamine (5-HT), substance P (SP) and vasoactive intestinal peptide (VIP), for unveiling the mechanism of intradermal needle therapy plus pinaverium bromide in treating IBS-D. Methods: A total of 123 IBS-D patients were divided into an observation group, a Western medication group and an integrated Western and Chinese medication group using the random number table method, with 41 cases in each group. The Western medication group was given oral pinaverium bromide, 50 mg each time and 3 times a day. The integrated Western and Chinese medication group was given additional Chinese herbal medicine Tong Xie Yao Fang, one dose each day. The observation group was given additional intradermal needle therapy on the basis of the Western medication group. The whole intervention lasted for 6 weeks. Before and after treatment, the scores of gastrointestinal symptoms, traditional Chinese medicine (TCM) symptoms, irritable bowel syndrome (IBS) symptom severity scale (IBS-SSS) and IBS quality of life (IBS-QOL) questionnaire, as well as the serum levels of 5-HT, SP and VIP were observed. The clinical efficacy was estimated. Results: The total effective rate was 92.7％ in the observation group, 68.3％ in the Western medication group and 78.1％ in the integrated Western and Chinese medication group. The total effective rate was higher in the observation group than in the other two groups, and higher in the integrated Western and Chinese medication group than in the Western medication group, showing statistical significance (all P<0.05). After treatment, the scores of gastrointestinal symptoms, TCM symptoms and IBS-SSS showed significant decreases in the three groups, presenting statistical significance compared with the baseline (all P<0.05); the scores of gastrointestinal symptoms, TCM symptoms and IBS-SSS were notably lower in the observation group than in the other two groups (all P<0.05), and lower in the integrated Western and Chinese medication group than in the Western medication group (all P<0.05). After treatment, the eight component scores of IBS-QOL showed significant increases in the three groups compared with the baseline (all P<0.05); the eight component scores in IBS-QOL were significantly higher in the observation group than in the other two groups (all P<0.05), and higher in the integrated Western and Chinese medication group than in the Western medication group (all P<0.05). After treatment, the serum levels of 5-HT, SP and VIP decreased markedly in the three groups compared with the baseline (all P<0.05); the serum levels of 5-HT, SP and VIP were significantly lower in the observation group than in the other two groups (all P<0.05), and lower in the integrated Western and Chinese medication group than in the Western medication group (P<0.05). Conclusion: Treatment with intradermal needle therapy plus pinaverium bromide results in significant improvements in the gastrointestinal symptoms and quality of life in patients with IBS-D of liver-qi stagnation and spleen deficiency pattern, and effectively regulates the gastrointestinal hormone production.

It is a common understanding that turbidity and precipitation of traditional Chinese medicine are easy to occur in the process of decocting. At present, our research group found that the cause of "multi-phase of traditional Chinese medicine decoction" mainly came from the interaction between the effective components of traditional Chinese medicine, especially the interaction of acid and base components. For example, the Liquorice and Rhizoma chinensis was a supramolecular system formed by a large number of active components in the decoction (>30%), and could stably exist in the decoction system. In this study, the supramolecular part was extracted, and the morphology of the supramolecular part was characterized by scanning electron microscopy and dynamic light scattering. It was observed that the supramolecular particles were uniform in size and regular in shape. The main components of supramolecular sites were identified by liquid mass spectrometry (LC-MSⁿ). The results of UV and IR spectra showed that the chemical components of Liquorice and Rhizoma chinensis in the co-decocting process collided with each other, and weak bonds were formed between the functional groups of the molecules, which then induced the aggregation to form supramolecules. Thereafter, Through the diarrhea model of mice, sensory evaluation and antibacterial activity evaluation found that Liquorice and Rhizoma chinensis decocted together enhanced the antibacterial activity of Rhizoma, and compatibility "reconcile" Rhizoma "big bitter cold" property compared with single decoction group and interval administration group. All animal experiments were approved by the Animal Ethics Committee of Beijing University of Chinese Medicine, and the relevant regulations of Beijing University of Chinese Medicine on experimental animals were strictly followed. In this study, supramolecular chemistry method was used to preliminarily discuss the scientific connotation of "increasing efficiency and decreasing toxicity" of Liquorice and Rhizoma chinensis combined decoction from three perspectives of "property, efficacy and taste", and provide new ideas for the basic research of "reconcile" compatibility of Liquorice.

OBJECTIVETo study changes in the radiographic appearance during weight-bearing and non-weigh-bearing in hallux valgus, and to analyse the correlation between the elasticity of plantar soft tissue of hallux valgus and the pain under the metatarsal head.

METHODSFrom May 2012 to October 2012, 240 feet of 120 patients with hallux valgus were enrolled in the study. The degrees of the pian under the metatarsal head of all the patients were observed. AP and lateral X-ray films of feet were taken on the condition of weight-bearing and non-weight-bearing. So the hallux valgus angle (HVA), the inter-metatarsal angle between the first and second metatarsals (IM1-2), the inter-metatarsal angle between the first and fifth metatarsals (IM1-5), top angle of the medial longitudinal arch (TAOTMLA),and anterior angle of the medial longitudinal arch (AAOTMLA) were measured on the X-ray films. The differences of HVA, IM1-2, IM1-5, TAOTMLA and AAOTMLA between two groups were compared, and the correlation between the changes of IM1-2, IM 1-5, TAOTMLA, AAOTMLA and the degree of the pain under the metatarsal head were analysed.

RESULTSOne hundred and forty-eight feet had the pain under the metatarsal head. The IM1-2, IM1-5 and TAOTMLA increased on weight-bearing position compared with those on non-weight-bearing position, but the HVA and AAOTMLA decreased on weight-bearing position compared with those on non-weight-bearing position. There was a moderate relationship between the changes of IM 1-2,IM1-5 and the degree of the hallux valgus deformity, as well as the relationship between the different of IM1-5 and the degree of the pian under the metatarsal head.

CONCLUSIONThe degree of the collapse of the arch of foot with hallux valgus becomes serious with its deformity increasing. The pain under the metatarsal head of hallux valgus increases with the increased changes of IM 1-2,IM 1-5 and TAOTMLA. Analysis of the X-ray observation indexes of hallux valgus on weight-bearing position and non-weight-bearing position has important significance in evaluating the degree of the collapse of the arch of foot with hallux valgus,preventing and curing the the pain under the metatarsal head.

OBJECTIVETo observe the effects of scorpion and centipede on interleukin (IL)-2, IL-4, IL-10 in the small intestinal mucosa and joint injury of rats with collagen induced arthritis (CIA).

METHODSSixty Wistar rats were randomly divided into 6 groups: the normal control group, the model group, the low dose scorpion and centipede group, the middle dose scorpion and centipede group, the high dose scorpion and centipede group, and the type II collagen treatment group. The joints' volume was measured 40 days after type II collagen (CII) induced rheumatoid arthritis model was established. The joint injury was observed by naked eyes. The expression levels of IL-2, IL-4, and IL-10 in the small intestine tissue homogenate were detected by enzyme linked immunosorbent assay (ELISA).

RESULTSThe joint injury score and volume of two hind limbs were obviously higher in the model group than in the normal control group since the 23rd day (P < 0.01). Rats were accompanied with red, swollen, and deformed foot toes and ankle joints. Walking was even affected. Meanwhile, the joint injury score and volume of two hind limbs were obviously lowered by medicated with 0.4, 0.2, 0.1 g/kg scorpion and centipede, as well as CII on the 32nd day after medication (P <0.05, P < 0.01). The expression levels of IL-2, IL-4, and IL-10 in the small intestine tissue homogenate were obviously lower in the model group than in the normal control group (P < 0.05, P < 0.01). Compared with the model group, only the expression levels of IL-2 and IL-4 in the small intestine tissue homogenate of the high dose scorpion and centipede group and the type II collagen treatment group significantly increased. The expression level of IL-10 significantly increased in the high and middle dose scorpion and centipede groups, as well as the type II collagen treatment group, showing statistical difference (P < 0.05, P < 0.01).

CONCLUSIONSScorpion and centipede could effectively release the joint injury of rats with CIA. Its mechanism might be correlated with increased expression levels of IL-2, IL-4, and IL-10 in the small intestine mucosa.
