Objective To observe the effect of acupoint magnetic therapy on coronary heart disease.Methods 80 patients with coronary heart disease were divided into treatment group( n =40) and control group( n =40).The treatment group was treated with acupoint magnetic therapy on the basis of conventional treatment,and the control group with conventional treatment.Clinical therapeutic effect,the scores of traditional Chinese medicine symptom were observed.Results There was significant difference between the two groups in the total effective rate and the scores of traditional Chinese medicine symptom[90.0％ vs 72.5％,(13.25 ± 3.68 ) vs (15.18 ± 4.16),all P ＜0.05].Conclusion Acupoint magnetic therapy for treatment of coronary heart disease has an obvious therapeutic effect.

Objective To study the correlation between pain, lower limb strength and physical function in patients with primary osteoporosis. Methods Fifty-seven female patients diagnosed with menopause-related low bone mass or primary osteoporosis using a GE calcaneus bone density detector were involved in this study. The muscle strength of their lower limbs was tested with a Biodex system 4 machine. Pain was assessed with a visual analogue scale, and physical function (PF) with the SF-36 instrument. Results Low back pain was significantly correlated with PF, and so was leg pain. Leg pain was also significantly correlated with the strength of the extensors of the dominant leg during low velocity and medium velocity movement. Leg pain was not, however, significantly correlated with the strength of the flexors of the dominant leg during low and medium velocity movement. Conclusions Pain predicts poor physical function in patients with primary osteoporosis or low bone density. During low and medium velocity movement, leg pain significantly predicts poor muscle strength in the extensors of the dominant lower leg, but it has no correlation with the muscle strength of the flexors.

OBJECTIVE:To optimize the preparation technology of Sinomenine topical paste. METHODS:Using“initial vis-cous force”,“holding viscous force”and“peeling strength”as index,heating and stirring time (A,h),heating temperature (B,℃) and the sequence of adding composition (softening agent,blank matrix and sinomenine)(C) as influential factors,the preparation technology of Sinomenine topical paste was optimized by orthogonal test and verified. At the same time,the content of sinomenine was determined by HPLC method. RESULTS:The optimal preparation technology of Sinomenine topical pasta was as follows as adding blank matrix and sinomenine,and then adding softening agent,heating at 80 ℃,stirring for 1 h. In verification test,RSD of comprehensive score for 3 batches of samples were 2.09%(n=3);average contents of samples were 6.7 mg/g, which was in line with the requirement of ≥6.0 mg/g. CONCLUSIONS:The optimal preparation technology of Sinomenine topical pasta is reasonable,stable and feasible. The paste shows good adhesiveness and is qualified in content.

Objective To study the effect of muskmelon juice on immune function of aged mice induced by D-galactose. Method Fifty male Kunming mice were randomly divided into five groups:normal control,aged model and three muskmelon juice (quadruple-diluted,double-diluted and stock juice) groups. The mice in aged model and three muskmelon juice groups were injected subcutaneously with D-galactose at dose of 200 mg/kg?d ,and the normal control with the normal saline of equal volume. The mice in three muskmelon juice groups were treated by intragastric administration twice daily with quadruple-diluted solution,double-diluted solution and stock liquid of muskmelon juice respectively,and the mice in normal control and aged model group with distilled water. Four weeks later,spleen and thymus were weighted,and the immunoglobulim and complement in serum were estimated. Results The thymus index of mice in aged model groop was much lower as compared with normal control. After administration with muskmelon juice,the thymus index was increased and the difference between stock juice and aged model group was significant. As compared with normal control,the serum IgG,IgM,C3,C4 contents of aged model were significantly lowered,but those in muskmelon juice group was increased. The IgG,C3,C4 contents of double-diluted and stock juice group were significantly higher than those of aged model. The spleen index and serum IgA contents fluctuated with same tendency. Conclusion Muskmelon juice can relieve the regression of immune organs in aging process and improve the immune function,suggesting to be effective in anti-aging process.

Objective To study the radiation-protective effects produced by the estrogenic activities of genistein(Gen) for providing experimental basis to develop the food for radiation protection. Method After blocking estrogen receptor (ER) activities by Tamoxifen and Faslodex,the effects of Gen on peripheral leucocytes and lymphocyte counts,serum haemolysin and delayed type of hypersensitivity of the mice were examined after exposure to 4 Gy ? radiation. Results Gen was shown to inhibit the decrease of peripheral leucocytes and lymphocyte counts and the decreased immune response of the ?-irradiated mice. Faslodex (ER? blocker) + Gen eliminated the protective effect of Gen and still caused the similar effects in hematological response and immune response after irradiation. Tamoxifen (ER? blocker) did not have these effects. Conclusion Gen can enhance the immune function in irradiated mice through activation of estrogen receptor ? pathway.

ObjectiveTo explore the mechanism of Taohong Siwutang in regulating the levels of inflammatory mediators， cysteine-dependent aspartate-specific protease Caspase-14， and recombinant envoplakin （EVPL） in the mouse model of psoriasis. MethodForty-eight BALB/c mice were randomized into blank， model， methotrexate tablets（3.6×10^-4 g·kg^-1）， and low-， medium-， and high-dose Taohong Siwutang groups（7.14，14.28，28.56 g·kg^-1）. The mouse model of psoriasis-like skin lesion was induced by applying 5% imiquimod cream on the back of mice， and drug intervention was carried out at the same time. The psoriasis area and severity index （PASI） was scored by photographing. Hematoxylin-eosin staining was employed to observe the pathological changes of the skin， which was evaluated based on the Baker score. The levels of interleukin （IL）-2， IL-17， IL-22， and IL-23 in the peripheral blood of mice were measured by the enzyme-linked immunosorbent assay. Immunohistochemical staining was adopted to detect the positive expression of Caspase-14 and EVPL in mouse skin lesions. Western blot and real-time polymerase chain reaction were employed to determine the protein and mRNA levels， respectively， of IL-2， IL-17， IL-22， IL-23， Caspase-14， and EVPL in mouse skin lesions. ResultCompared with the blank group， the model group showed increased PASI score and Baker score， elevated levels of IL-2， IL-17， IL-22， and IL-23 in the peripheral blood， up-regulated mRNA and protein levels of IL-2， IL-17， IL-22 and IL-23， and down-regulated mRNA and protein levels and positive expression of Caspase-14 and EVPL in skin lesions （P<0.05）. Compared with the model group， drug interventions reduced the PASI score and Baker score， lowered the levels of IL-2， IL-17， IL-22， and IL-23 in the peripheral blood， down-regulated the mRNA and protein levels of IL-2， IL-17， IL-22， and IL-23， and up-regulated the mRNA and protein levels and positive expression of Caspase-14 and EVPL in skin lesions （P<0.05）. ConclusionTaohong Siwutang demonstrates good anti-inflammatory effect and skin barrier repair function in the treatment of psoriasis. It can significantly reduce the levels of inflammatory mediators in the peripheral blood and skin lesions and promote the expression of Caspase-14 and EVPL involved in skin barrier repair in the mouse model of psoriasis.
