Objective To explore methods for establishinga cellu lar injury model of blood stasis syndrome (BSS). Methods Two experiments were c arried out. In the first experiment,the injured vascular endothelial cell model of BSS was established by the culture of vascular endothelial cell, and in the seco nd experiment, the vascular endothelial cell injured by the serum of BSS rabbit was cultured. Results In the first experiment, pathological features and end ocrine dysfunction in the primary cultured endothelial cell were similar to the B SS rabbit model, but the above changes did not remain in the subculture. The above changes were also found in the second experiment and were easy to be repea ted. Conclusion The injured vascular endothelial cell model of BSS establis hed b y the above methods reflects or partially reflects the structure and function of BSS rabbit model and the patients with BSS, and can be used to study the pathol ogical mechanism of BSS and therapeutic effect of blood_circulation activating a nd blood_stasis removing herbs.
3. Advances in studies on inhibitors of NF-κB derived from plant
Chinese Traditional and Herbal Drugs 2014;45(19):2855-2863
Plant secondary metabolites (natural products) have been a source for many medicines. Their functions in plants often remain unknown, but in recent years there are more and more new compounds isolated and identified and their medicinal potentials are investigated. The major classes of plant natural products and various derivatives thereof are: phenolics, terpenoids, alkaloids, and lignans. The major transcription factor, nuclear factor-κB (NF-κB) is a central downstream regulator of inflammation, cell proliferation, and apoptosis which controls the expression of more than 500 genes. It plays an essential role in several aspects of human health including the development of innate and adaptive immunity. The degradation of NF-κB is associated with many ailments including cancer and chronic inflammatory diseases. In spite of a vast literature describing NF-κB inhibitors from many natural or synthetic sources, such modulators have not been fully tapped for therapeutic purposes and the search for effective and specific inhibitors for therapeutic use with fewer side effects is still relevant and ongoing. Plant-derived phytochemicals are promising the lead compounds to develop potent and safe inhibitors for cancer and inflammatory disorders driven by NF-κB. The recent knowledge on the plant-derived phytochemicals and their major NF-κB molecular targets are briefly reviewed in this paper.

Pulse-activating injection has the functions of supplementing qi and nourishing yin, and recovering pulse from a collapse state. It is applied in hypotension caused by serious infection or hypovolemia extensively. Pulse-activating injection can be also used to treat hypotension caused by tracheal intubation with good effects. Appropriate application according to state of illness is very important, such as controlling infection and supplementing blood-volume, etc. When applied in cardia insufficiency, vasodilating agent should be used together to regulate dropping rate.

Objective To study the relieving cough effect ofPuji-Xuanfei-Xiaodu decoction on acute bronchitis.Methods 87 patients with acute bronchitis of exterior cold and interior heat were randomly divided into two groups(44 cases in a therapy group and 43 cases in a control group).Puji-Xuanfei-Xiaodu decoction was given to the patients in the therapy group and acute bronchitis syrup was given to the control group, to observe the influence on symptoms of cough, sputum, fever and headache. The course of treatment was 7 days. Results On the reliving cough aspect, 28 cases (63.6%) showed cure effect and 13 cases (29.5%) effctive, the total effective rate was 93.2% in therapy group with 44 cases; while in control group (43 cases), 15 cases (43.9%) showed cure effect and 23 cases (53.5%) effctive, the total effective rate was 88.4%. The symptoms of cough, phlegm, fever, headache and aversion to wind were significantly decreased in two groups. In therapy group, the numbers of cure effect, remarkable effect and efficacy were 22 (50%) ,11(25%) and 8 (18.2%) cases respectively, the total effective rate was 93.19% while the numbers of cure effect, remarkable effect and efficacy were 14 (32.6%) ,8(18.6%) and 12 (27.9%) cases respectively, the total effective rate was 79.07% in control group. The total effective ratio of two groups had significant difference (P>0.05).ConclusionsPuji-Xuanfei-Xiaodu decoction is effective in relieving cough.

Objective To observe the protective effect of Xuefu Zhuyu Decoction (XZD) on vascular endothelial cells (VEC) injured by the serum of blood_stasis_syndrome ( BSS) rabbits. Methods The morphological features of VEC cultured with norma l rabbit serum (Group A), BSS rabbit serum(Group B), the serum of normal rabbit medicated with XZD(Group C) and the serum of BSS rabbit medicated with XZD(Group D) were observed respectively under light microscope and electron microscope. Results Under light microscope, VEC was shrinked, intercellular space widene d and cytoplasm contained dark granules in Group B. The change of intercellular space was not obvious in Group D. Under electron microscope, pinocytotic vesicle s increased, rough endoplasmic reticulum (RER) decreased and dilated, mitochondr ia became smaller and indistinct and only a small amount of microvilli appeared on cell membrane with top expanded and merged in VEC of Group B as compared with Group A and Group C. Less RER but no dilatation and fewer microvilli without to p merged were found in VEC of Group B. Conclusion The serum of BSS rabbits c an injury normal VEC cultured in vitro and XZD exerts a certain protective effe ct on VEC injured by the serum of BSS rabbits.

AlM: To observe the early tear film changes after trabeculectomy using Keratograph 5M.METHODS:Fourty-one patients (46 eyes) of glaucoma who underwent trabeculectomy were involved. First tear break up time ( FTBUT ) , average tear break up time (ATBUT), non-invasive tear meniscus height (NlTMH), lipid layer thickness and meibomian gland scores were measured at 1d preoperatively and at 1d, 1wk, 1mo postoperatively.RESULTS:At 1d, 1wk and 1mo postoperatively, FTBUT and ATBUT decreased greatly (P<0. 05), as well as lipid layer thickness (P<0. 017). NlTMH at 1d postoperatively increased significantly, but at 1wk and 1mo postoperatively decreased greatly (P<0. 05). There was no significantly difference in meibomian gland scores between preoperation and postoperation (P>0. 05). CONCLUSlON: Keratograph 5M could be used to evaluate tear film function rapidly and accurately. Trabeculectomy significantly alters tear film stability and tear secretion in the short term after operation.

Objective Using surface electromyography (sEMG) techniques to investigate the patterns of frequency domain indexes of sEMC signals recorded from adolescent idiopathic scoliosis (AIS) patients' paraspinal muscles. Methods Twenty-five AIS patients were enrolled. All the patients undertook the Biering Sorensen test ( BST) ,the object-lifting test and a semi-bridge test, the ME3000P sEMG instrument was applied to record the electric activities of paraspinal muscles (convex/concave) of all subjects, and the time domain indexes such as averaged EMG(AEMG)and spectrum area(SPA) were analyzed, values in three tests were compared with one way ANOVA. Results The differences of AEMGs and SPAs on both convex and concave sides among the three tests showed no statistical significances (P = 0. 10,0.23, 0. 24 and 0. 45, respectively). Conclusions Any of the Biering Sorensen test( BST) , the object-lifting test or the semi-bridge test can be used to test the electric activities of paraspinal muscles (convex/concave) of AIS patients.
