One hundred and seventy-two strains of endophytic fungi were isolated from Taxus mairei,Cephalotaxus fortunei and Torreya grandis cv.merrillia.The result of the antifungal assay shows that ninety strains of the fungi have antagonism against one or more botanical pathogenic fungi,such as Neurospora sp.,Trichoderma sp.,Fusarium sp.etc.The percentage of antifungal strains to tested strains are as follows:40% Cephalotaxus fortunei,54.2% Taxus mairei,57.1% Torreya grandis cv.merrillia.Thirty-five strains have high antifungal activities,and their inhibition zone diameter is at least 15mm.The active endophytic fungi were identified as 18 genera,most of which belong to Paecilomyces and Fusarium etc.

In this study, the ameliorative effects of Flos Abelmoschus manihot on mice with chronic inflammatory bowel disease (IBD) were investigated and its effects on the structure of the intestinal flora as well as the lipid profile in feces of IBD mice were analyzed. All animal welfare and experimental procedures followed the regulations of the Animal Ethics Committee of Nanjing University of Chinese medicine. A mouse model with chronic IBD induced by dextran sulfate sodium (DSS) was used to evaluate changes in body weight, disease activity index (DAI), colonic histopathological damage as well as gene expression levels of inflammatory factors in the colon. Fecal samples from mice in each group were collected and subjected to Illumina high-throughput sequencing to detect the abundance of intestinal flora; samples were analyzed by UHPLC-Q-Exactive^® HF Quadrupole-Orbitrap^® of untargeted lipidomics, which detects lipid content in feces. Administration of Flos Abelmoschus manihot could significantly restore the body weight and ameliorate colonic histopathological damage in IBD mice. Sequencing of the gut microbiota revealed that the species diversity and richness of the gut microbiota in IBD mice were decreased, with a significant increase in the abundance of Verrucomicrobia and a significant decrease in the abundance of Bacteroidetes; Flos Abelmoschus manihot significantly increased the richness and diversity of intestinal microbiota in IBD mice, increased the number of taxa species at each level, and restored the abundance of bacteria in the phylum Bacteroidetes. Analysis of fecal lipid profiles identified the most significant changes in sphingolipid and glycerophospholipid metabolic pathways in IBD mice, with Flos Abelmoschus manihot inhibiting ceramide and sphingomyelin synthesis in sphingolipid metabolism. In summary, Flos Abelmoschus manihot can effectively improve the disease condition of mice with chronic IBD, and it has the effect of regulating intestinal flora homeostasis and lipid metabolism, but the related mechanism between the two still needs to be deeply explored.

Euphorbia kansui (EK) is a toxic herbal drug, and often used after vinegar-processing to reduce its toxicity. In present study, a 1H-NMR based metabonomic approach was used to evaluate the detoxification effect of vinegar-processed EK. The water extracts of EK and VEK were administered orally to male SD rats at doses of 9 g x kg(-1) x d(-1) for 1 week, respectively, and one more week observation was further conducted. The control group was orally given with saline. Histopathological studies of liver samples on the 8th and 15th day were conducted, and the metabolites of rat urine and liver were analysed by 1H-NMR. Histopathological studies of liver samples from EK and VEK treated rats showed no negative impacts. In metabonomic analyses of urines, changes of metabolites indicated liver damages, kidney lesions and imbalance of gut microbes in the second week. VEK-treated rats showed a quite lower toxicity compared with EK-treated ones. The present study revealed that the metabonomic approach might be helpful for the evaluation of toxicity of EK and detoxic effect of VEK.

OBJECTIVETo investigate the characteristic of colonic transmission in functional constipation (FC) and the effect of traditional Chinese medicine (TCM) Sini Powder (SP) on it.

METHODSThe colonic transmission time (CTT) of 36 patients with FC (the FC group) and 22 healthy subjects (control group) was measured through colonic transmission test, and CTT of entire colon and that of various subsections was calculated with Hinton method and Arhan method respectively. After then, the FC group was treated with SP for 7 days, and CTT was detected again after treatment.

RESULTSBefore treatment, body mass index (BMI) was higher, CTT of entire colon, left half colonic section, and sigmoid-rectal section were longer in the FC group than those in the control group (P < 0.05), no statistical difference in CTT of right half colon was found between the two groups (P > 0.05). After FC patients being treated with SP, their CTT of whole colon, left half colonic section and sigmoid-rectal section were significantly shortened (P < 0.05).

CONCLUSIONFC patients were characterized by increased BMI and CTT prolonged and unevenly distributed in subsections, especially in the left half colon, sigmoid and rectum; SP could shorten the CTT in FC patients.

OBJECTIVETo investigate the effects of glycyrrihizic acid (GA) and prednisone on renal injury in chronic aristolochic acid nephropathy (AAN) rat model.

METHODSNinety-eight male Wistar rats of SPF grade were randomly divided into 4 groups, the normal control group (n = 20), the GA group, the model group, and the prednisone group, 26 rats in each group. Rats in the latter 3 groups were made into AAN model by administration of aristolochic acid (AA, contained in extract of Caulis Aristolochiae Manshuriensis) 20 mg/(kg x d) by gastric gavage, and equal volume of drinking water was given to rats in the control group. Medication was started 2 h later, the GA group was treated with GA 25 mg/(kg x d), the prednisone group with prednisone 3.15 mg/(kg x d), and to the other two groups equal volume of drinking water was given. Body weight was measured weekly, renal function related indices and morphology of the renal tissue were examined at the 4th, 8th and 12th weekend.

RESULTSAlong with the feeding time, body weight in the control group increased steadily, while that in the treated groups increased slowly. The ratio of serum creatinine/body weight increased markedly in the model group, while it significantly lowered in the treated groups. Morphological examination showed that the structural injury in the treated groups was milder than that in the model group, and its degree of fibrosis was milder also (15% - 20% vs 30%). Electronmicroscopy showed that AA induced, injury degeneration and necrosis of renal tubular epithelial cells, and markedly injured the cell organs, such as mitochondria, and induced nuclear variation, while in the treated groups, it was mainly limited in renal tubule, with normal cell organs, few nucleolus variation and less interstitial collagen fibers.

CONCLUSIONGA and prednisone could reduce the serum creatinine level, improve renal function, relieve the renal morphological changes, and decrease the inter stitial fibrosis, showing a definite preventing effect on chronic AAN in rats.

Objective To evaluate the effect and clinical value of open surgery combined ultrasound-guided Mammotome in the treatment of multiple breast lumps. Methods Four hundred and forty-four patients in our hospital from Jan. 2006 to Jun. 2008 were divided into 3 groups, who underwent classical open surgery, ultrasound-guided Mammotome operation, or combined therapy respectively and followed by post-operation visits reguarly. The operation effects were compared between the 3 groups. Results Compared with the classical open surgery, combined therapy had no difference in time of procedure and procedural bleeding, but had lower incidence of local skin, better incision condition and higher satisfaction of patients. Compared with ultrasound-guided Mammotome operation, combined therapy took less time in procedure, and in the same time had less procedural bleeding, lower post-operation complication and higher patients satisfaction. Conclusions Combined therapy has high complete removal rate, low post-operation complication as well as cosmetic effect. It has special advantages over the other two kinds of surgery, so it has wide clinical application.
