Tanshinones are a large class of hydrophobic natural products isolated from traditional Chinese herb Salvia miltiorrhiza Bunge and related plants. Tanshinones include tanshinone ⅡA, cryptotanshinone, tanshinone I, dihydrotanshinone, and so on. Both the tanshinones and the salvianolic acids have been identi-fied as the characteristic and main active ingredients of Salvia miltiorrhiza Bunge with cardiovascular protective activities. Ac-cumulated data in recent years have revealed that tanshinones possess remarkable anti-cancer activities both in vivo and in vitro. In this review, we summarize the latest progress of the an-ti-cancer effect and the underlying mechanisms of tanshinones, particularly with emphasis on tanshinone ⅡA, which might pro-vide reference for the further research and development of these compounds.

Objective To explore the effect of suction toothbrushing in oral care of patients with dysphagia.Methods sixty patients with dysphagia from the neurology department and rehabilitation department in our hospital were equally divided into the experiment group and the control group randomly: the former used suction toothbrushing for oral care and the latter physiological saline for oral care.The two groups were compared in respect of bad breath,oral cleanliness,time for conducting oral care,stomatitis, oral ulcer and pathogenic bacteria in oral cavity.Results The time for conducting oral care in the experiment group was significantly shorter than that in the control group(P<0.001).The score on oral cleanliness of the experiment group was significantly higher than that in control group(P<0.001).The bad breath,stomatitis or oral ulcer,and mucosa damage in the experiments group were all lower than those in the control group.The number of oral bacteria on the 5th day in the experiment group was smaller than that in the control group(P<0.005).Conclusion For the patients with dysphagia,the suction toothbrushing may be effective for cleaning the mouth,reducing oral complications and improving the satisfaction degree.

Systematic pharmacological evaluation of material basis for the efficacy of Chinese herbal formula is one of the key issues in Chinese materia medica(CMM),which is in urgent need of solution.However,its scientific connotation is still controversial in academic circles.The material basis for the efficacy of Chinese herbal formula is the total non-endogenous bioactive compound(derived either directly or indirectly from this formula) exerting the therapeutic effects,which is generated by the interaction of the formula with human body and reaches certain concentration in the target organs or tissues.Systematic evaluation of material basis for the efficacy of Chinese herbal formula is the cornerstone of modernization and internationalization of CMM,while the quality control of CMM is its prerequisite.

The proliferation of vascular smooth muscle cells is closely related to the pathogenesis of a variety of diseases, such as atherosclerosis, hypertension, diabetes, vascular restenosis, and etc. A proper model for smooth muscle cell proliferation can be served as an important tool for exploring the molecular mechanisms of smooth muscle cell proliferation and the screening of potential inhibitory agents. Various factors can induce the proliferation of smooth muscle cells with different mechanisms and pathological significance. The ox-LDL, AGEs, angiotensin II (AngⅡ), high glucose, tumor necrosis factor (TNF) and etc. have been successfully applied in the establishment of smooth muscle cell proliferation model. This article summarized the most commonly used models for smooth muscle cell proliferation. The inhibitory effects of Chinese herbal medicine, especially the isolated pure compounds were discussed. It was aimed to provide references for the screening of smooth muscle cells based medications as well as studies on related research and development of Chinese herbal medicine.

Thirty assistant general practitioners (GPs) of Jiading District Shanghai were trained for clinical skills and communication skills by using standardized patients (SP) in outpatient department from January to April 2014.The scores of clinical skills and communication skills were evaluated and compared before and two months after training.The results showed that the score of clinical skills [(72 ± 5) vs (56 ± 7), t=7.871, P＜0.05] and communication skills [(71 ±4) vs (45 ±5), t =9.573, P＜0.05] were significantly improved after training.After training, the scores of medical history taking [(36 ±5) vs (28 ± 6), t =4.352], clinical thinking [(17 ± 2) vs (14 ± 3), t =3.974], health education [(3 ± 1) vs (2 ± 1), t =3.090] and medical record v,riting [(13 ± 1) vs (8 ±2), t =5.317] were significantly higher than those before training (all P ＜ 0.05).But there was no difference in reception time management [(4 ± 0) vs (4 ± 0), t =1.025] before and after training (P ＞ 0.05).After training, the scores and the proportions of the trainees qualified for building physician-patient relationship [(20 ± 3) vs (15 ± 4), t =4.056],collecting information and providing feedback [(22 ±4) vs (13 ±3), t =4.682], understanding complaints from patients' perspective [(5 ± 2) vs (3 ± 2), t =3.107], sharing information and obtaining informed consent [(19 ± 4) vs (11 ± 5), t =4.322] and closing consultation [(6 ± 2) vs (3 ± 1), t =2.987] were higher than before training (all P ＜ 0.05).The results indicate that training by using SP can effectively improve the clinical skills and communication skills of assistant GPs.

OBJECTIVE To investigate the clinical and etiologic characteristics and treatment of central venous catheter-related(sepsis).METHODS Forty cases of patients with central venous catheter-related sepsis and their clinical manifestation,etiologic profiles and outcome of treatment were retrospectively analyzed.RESULTS Forty six strains were isolated including 23 strains of Gram-positive cocci,19 of Gram-negative bacilli and 4 of fungi.The most frequent(isolates) were Staphylococcus epidermidis.CONCLUSIONS The most common organism causing CRS is S.epidermidis;the key preventive measure is to avoid inner and outer pollution of catheter;antibiotic lock-technique can be taken for the treatment of uncertain CRS.If it is no effect after 24-48 hours,it is necessary to remove venous catheter promptly.

This study is to investigate the effect of artesunate on transforming growth factor-beta1 (TGF-beta1) induced epithelial-mesenchymal transition (EMT) and its possible mechanism. After the in vitro cultured RLE-6TN cells were treated with TGF-beta1 then artesunate intervened on it, after 24 h, expression of the markers of mesenchymal cell was assayed using Western blotting and real-time PCR analysis. Western blotting was also used to detect the effect of TGF-beta1 on the Smad3 and Smad7 expressions of RLE-6TN cells. Morphological alterations were examined by phase-contrast microscope, and ultrastructure changes by electron microscope. Incubation of RLE-6TN cells with TGF-beta1 resulted in the up-regulation of the expression of the mesenchymal cell markers, after artesunate intervened on it, resulted in the down-regulation of the expression. Meanwhile, incubation with artesunate intervened on RLE-6TN cells could lead to the apparent down-regulation of the expression of Smad3 and up-regulation of Samd7 and the transition of RLE-6TN cells to mesenchymal-like by TGF-beta1 induction, after artesunate intervened on it, RLE-6TN cells to epithelial-like. TGF-beta1 induced epithelial-mesenchymal transition process; artesunate can inhibit TGF-beta1-induced epithelial-mesenchymal transition process, the possible mechanism is up-regulation of the expression of Smad7 and down-regulation of the expression of Smad3, meanwhile inhibits phosphorylation of Smad3.

Objective To study the tumorigenetic characteristics of side population (SP) cells and their exsistence in gastric cancer cell lines and tissues.Methods Flow cytometry and the DNA-binding dye Hoechst 33342 staining were used to analyze sorted SP cells in 3 gastric cancer cell lines(SGC-7901,BCIC-823 and MKN28).SP cells and non-SP cells(main population cells)isolated from SGC-7901 cell line weresubcutaneously injected into 36 nude mice with 500,5000 or 50 000 cells per mouse,respectively.Thetumorigenity was observed 8 weeks after injection.The expression of ATP-binding cassette sub-family Gmember 2(ABcG2)mRNA in three gastric cell lines and its level in gastric cancer tissues were detected by real-time PCR and immunostaining.respectively.Results The proportion of SP cells was accounted for 1.0%in SGC-7901 cells and 1.3%in BGc-823 cells.No SP cell was found in MKN28 cells.As low as 500 SP cells or 50 000 non-SP cells could initiate tumors in mice.The expression of ABcG2 mRNA was higher in SGC-7901(O.162)and BGC-823(O.096)cell lines than that in MKN28 cell line(0.005).The value of AtCG2 mRNA/beta-aetin mRNA and protein in gastric cancer tissues was different from those in gastritis tissues.Condasimm SP cells have strong ability of tumorigenesis compared with non-SP cells.The expression of ABCG2 is found in gastric cancer tissues and part gastritis tissues.The more the SP cells in gastric cell lines,the higher the expression of ABCG2.
