This research uses six Agrobacterium rhizogenes R1601, R15384, R1000, A4, R1025 and R1 to infect silymarin explants to induce hairy roots and silibin. All of the six A. rhizogenes can induce Silybum marianum to generate hairy roots and the A. rhizogene A4 shows comparatively high infection on the plant. This research determines the condition to induce silymarin hairy roots by the factors of infection time, pre-culturing, co-culturing and pH value. The fact that MS liquid medium fits the proliferation of silymarin hairy roots is determined. Through PCR molecular identification, it can be seen that the DNA plasmids in the A. rhizogenes are successfully integrated into the genome of transformed roots. Using liquid chromatography, it is determined that the silibin content in silymarin hairy roots is 2.5 times that in the plant In this research, the silymarin hairy roots culturing system is established, which lays a foundation for the study of culturing silymarin hairy roots and producing silibin.

Astragalus, which was first documented in Shennong Bencao Jing, is the dried root of Astragalus membranaceus (Fisch.) Bge. or Astragalus membranaceus (Fisch.) Bge. var. mongholicus (Bge.) Hsiao. The active ingredients astragalus membranaceus saponins (AMS), astragalus polysaccharides (APS) and astragalus flavonoids (AFS) have pharmacological effects such as anti-tumor properties, lowering blood sugar, regulating lipid metabolism, cardiovascular protection, anti-oxidation, bone protection, anti-fibrosis, etc. Fibrosis affects almost all organs, particularly vital organs such as the lungs, liver, heart and kidneys. The primary pathological changes of fibrosis involve abnormal increase of myofibroblasts and excessive deposition of extracellular matrix (ECM) components, which lead to the formation of scar tissue, ultimately resulting in fibrosis and even functional loss or failure of organs, which seriously threatens human health and life. Recent, studies have shown that Astragalus membranaceus has a good therapetuic effect on organ fibrosis. This article reviews the current advances of Astragalus in the prevention and treatment of fibrosis of lungs, liver, heart, kidneys and other important organs.

Advocating green, nature, environmental protection, safety and the pursuit of efficacy are the trends of cosmetics in the world. In recent years, more and more Chinese herbal extracts with mild, high safety and small irritation are applied to cosmetics as the natural additives. This has become a new hot spot. The recent application advances of Chinese medicine raw materials in cosmetics are overviewed according to their main functions. This review will provide useful references for the future development and application of Chinese medicinal herbs cosmetics.

OBJECTIVETo investigate the placement of a long tube into the small intestine under fluoroscopic guidance and to evaluate its decompression effect on early postoperative small bowel obstruction (EPSBO).

METHODSFifty-four patients with EPSBO requiring decompression between April 2010 and July 2014 were enrolled in the study. Insertion of a long tube was guided by fluoroscopy. We first used the guide wire to pass the pylorus and then used the 10 Fr feeding tube as an exchangeable tube to put the superstiff wire into the duodenum. Finally the long tube could be passed over the guide wire through the pylorus into the intestine. The total procedure time, the radiation exposure time, and the incidence of complications were evaluated.

RESULTSThe long tubes passed into the jejunum on initial insertion for all patients, so the success rate of this technique was 100%. The long tube was inserted into ileum in 18 patients. The mean total procedure time was 34.4 ± 8.6 minutes, and the mean radiation exposure time 18.9 ± 6.8 minutes. A total of 47 patients (87%) experienced full recovery following long-tube decompression and without the need for surgical intervention.

CONCLUSIONSUsing the wire-exchange technique, it is easy to place a long tube into the small bowel under fluoroscopic guidance. This decompression method is safe and effective for management of EPSBO.

OBJECTIVETo study the numbers and locations of spermatic veins, testicular arteries, and lymphatic vessels in the spermatic cord of the varicocele patient under the laparoscope.

METHODSFifty-seven varicocele patients received laparoscopic ligation of spermatic veins, during which we recorded the numbers and observed the locations of spermatic veins, testicular arteries, and spermatic lymphatic vessels.

RESULTSDuring the surgery, we identified 3.3 ± 1.2 spermatic veins, 1.4 ± 0.9 testicular arteries, and 4.3 ± 1.1 spermatic lymphatic vessels. No statistically significant differences were observed between the two side in the numbers of the spermatic veins, testicular arteries and spermatic lymphatic vessels (P > 0.05). The testicular arteries were seen on the exterior of the spermatic veins and winding around them, while the spermatic lymphatic vessels mostly between the veins.

CONCLUSIONThe spermatic veins, testicular arteries, and lymphatic vessels in the spermatic cord of the varicocele patient have their specific anatomic characteristics. Laparoscopic identification of these vessels may contribute to the surgical treatment of varicocele.

Objective:To study the in vitro antimicrobial activity of traditional Chinese medicine herbal pair of euphorbia humifusa Willd. and portulaca oleracea L. . Methods: The antibacterial effect in vitro of the traditional Chinese medicine herbal pair and the single herb of euphorbia humifusa Willd. and portulaca oleracea L. was studied on staphylococcus aureus, escherichia coli and pseudo-monas aeruginosa by the 2-fold dilution method and the broth micro-dilution method in a 96-well plate. The minimum inhibitory con-centration ( MIC) , minimum bactericidal concentration ( MBC) and the diameter of inhibition zone were determined. Results:The ex-perimental strains showed the different sensitivity among the traditional Chinese medicine herbal pair and the single herb. The antibac-terial and bactericidal activity of the traditional Chinese medicine herbal pair was the most obvious(P<0. 05). As the temperature in-creasing, the antibacterial activity of all water extract on different experimental strains changed. The results of MIC and MBC showed that the effects of water extract on escherichia coli were strongest, that of stapphylococcus aureus were secong, ant that of pseudomonas aeruginosa were relatively weak. Conclusion:The traditional Chinese medicine herbal pair of euphorbia humifusa Willd. and portulaca oleracea L. has antibacterial and bactericidal activity in varying degrees on the experimental strains with some differences, and the changes in the application forms of traditional Chinese medicines has great influence on the antibacterial and bactericidal ability.

Objective To establish a method for culturing neonatal mice cardiomyocytes, and construct an in vitro model of cardiomyocytes for assessing the cardiac toxicity of chemicals. Methods Hearts of neonatal mice of 1 day old were digested with enzyme mixture of trypsin/collagenase type Ⅱ/dispase and the cell suspensions were pre-plated to flask for a short time and then seeded on coated dishes. The cultured cells were treated with 5-fiuorine-deoxy-uridine(15 μg/ml)and uridine(35 μg/ml)to enrich cardiomyocytes that were identified according to the morphology and immunocytochemistry of α-actin antigen. Cardiac myocytes were incubated with 0-64 μg/ml of a fusarium mycotoxin butenolide(BUT) for 12 h. Cell viability was then evaluated by MTT assay. Microscopic observation showed that BUT induced significant morphological changes including cellular swelling, vacuolation and breakage of muscle fibers. Results It was found that 96% of the cultured cells were cardiomyocytes and the myocytes kept beating after 90 days of culture. Concentration-dependent decreases in cell viability following exposure of cardiac myocytes to BUT were observed. Conclusion The results indicated that relatively pure primary culture of neonatal mice cardiomyocytes is successfully established. BUT possesses the potential to induce myocardial toxicity.
