Two isomeric pentacyclic-triterpenic acids were isolated from the root of Ampelosis brevipedunculata var hancei Rhed for the first time. One acid was identified as oleanolic acid by means of physico-chemical properties and spectral analysis. The other one was acetylatcd and confirmed by X-ray diffraction analysis. This acid was proved to be betulinic acid.

From Hippophae rhamnoides L.oil free seed, acylated ?-sitosterol ?-D-glucoside was isolated.By alkaline hydrolysis, acylated steryl glucoside yielded ?-sitosterol-?-D-glucoside and fatty acids which were identified as palmitic, stearic, oleic, linoleic, linolenic and decadecylenic acids.These results suggest that acylated steryl glucoside may be esterified forms of ?-sitosterol-?-D-glucoside which was identified by means of physicochemical properties, spectral analysis and synthesis, ?-sitosterol ?-D-glucoside in relatively small doses (i. e. 12mg/kg) was found to be an effective agent in the treatment of acetic acid-induced chronic ulcer in mice.

Objective To observe the bacteriostatic effect of single herbs, traditional complex prescription and ultra-micro powder of Qiweibaizhusan. Methods The inhibiting zone and MIC of single herb and compound of Qiweibaizhusan on Escherichia coli, Staphylococcus aureus, Eubacterium aerofaciens, Pseudomonas aeruginosa, Salmonella sp, Saccharomyces cerevisiaes and Candida glabrata were measured by filter paper method. Results The growth of the tested bacteria and yeast except Staphylococcus aureus and Salmonella sp were inhibited by ginseng. The antibacterial effect of licorice was the best, and only Pseudomonas aeruginosa’s growth was not inhibited by licorice. The growth of Staphylococcus aureus and Eubacterium aerofaciens were inhibited by Agastache rugosa. The growth of Escherichia coli, Staphylococcus aureus, Eubacterium aerofaciens and Pseudomonas aeruginosa were inhibited by Poria cocos. Only Eubacterium aerofaciens’s growth was inhibited by Radix aucklandiae and fried Atractylodes macrocephala. The growth of all the bacteria and yeast were not inhibited by Radix puerariae. The growth of Staphylococcus aureus, Eubacterium aerofaciens and Salmonella sp were inhibited by the traditional decoction and ultra-micro powder of complex prescription of Qiweibaizhusan, and all the MIC of ultra-micro powder were smaller than the traditional decoction. Conclusion The main antibacterial component of Qiweibaizhusan was ginseng and licorice. The inhibiting effect of ultra-micro powder on bacteria was better than traditional decoction of Qiweibaizhusan in vitro.

Background: Anal fissure is one of the most common anal-rectum diseases, and approximately 10 percent patients with chronic anal fissure ultimately receive surgery. Relieving postoperative pain and protecting functions of the sphincter are central issues for coloproctologists. Objective: To evaluate the efficacy and safety of anoplasty in the treatment of chronic anal fissures. Design, setting, participants and interventions: In this prospective, multicenter, randomized controlled trial, 120 adult patients with chronic anal fissure were referred from Department of Coloproctology of Yueyang Hospital of Integrated Traditional Chinese Medicine Affiliated to Shanghai University of Traditional Chinese Medicine, Shanghai Ninth People's Hospital Affiliated to Shanghai Jiao Tong University School of Medicine and Shanghai Municipal Hospital of Traditional Chinese Medicine. The patients were enrolled from January 2009 to April 2010 and randomly divided into study (mucosa advancement flap anoplasty, abbreviated as anoplasty) group and control (fissurectomy) group. The two groups were assessed separately, and the main outcome measures were observed for 2 weeks, with a short-term follow-up for 6 weeks. Main outcome measures: Degree of pain, haemorrhage and anal canal pressure were observed and recorded preoperatively, and on the third day, the fourteenth day and the sixth week postoperatively. The wound healing time was also recorded. Surgical complications of the two groups were recorded and compared on the third day and the sixth week postoperatively. The curative effects associated with the surgery were analyzed on the fourteenth day and the sixth week after surgery and the therapeutic results were evaluated. Results: Three patients were dropped out due to the early discharge from hospital and losing connection (1 in study group and 2 in control group). Overall the surgery showed that the anoplasty group had better results than the fissurectomy group in the curative effect on the sixth week after operation (P<0.05). Time of wound healing in the anoplasty group was (17.22±4.41) d and was better than (21.24±7.44) d of the fissurectomy group (P<0.05). Concerning the relief of wound pain, the anoplasty group achieved better results than the fissurectomy group at the third day, the fourteenth day and the sixth week after operation (P<0.05). Anoplasty reduced bleeding and had better efficacy than the fissurectomy at the third day and the fourteenth day after operation (P<0.05), however, there was no statistical difference at the sixth week after operation (P>0.05). There were no significant differences in relieving the anal canal pressure (P>0.05) and the surgical complications (dysuria, edema of anal margin, fever, infection, anal incontinence and anal deformation) between the two groups (P>0.05). None of the patients suffered postoperative complications by the sixth week after operation. Furthermore, there was no recurrence in either of the two groups at six weeks after operation. Conclusion: The results indicate that anoplasty for chronic anal fissures has advantages such as better therapeutic effects, less postoperative pain, a shorter healing time and no incidence of anal incontinence.

Objective:To explore the features the gait of elderly persons with type 2 diabetes and peri-pheral neuropathy.Methods:Twenty patients no less than 60 years old with type 2 diabetes and peripheral neuropathy (DPN) formed a DPN group, while 20 counterparts with type 2 diabetes but without peripheral neuropathy composed the DM group, and another 20 healthy counterparts served as a control group. The three groups were tested using the Swedish Qualisys motion capture system and their walking speed, step length, step width, stride frequency and stride length, bipedal foot support phase time, single foot support phase time, peak plantar pressure, and regional-holding time were collected and compared.Results:The average walking speed, stride length and stepping frequency of the DPN group were all significantly lower than the other 2 groups′ averages. Their bipedal support phase was significantly longer, but their single foot support phase time was significantly shorter. And in the DPN group the average first and second peak plantar pressures and the second peak pressure time were significantly greater than the other groups′ averages.Conclusions:Elderly patients with type 2 diabetes and peripheral neuropathy have significant gait abnormalities, decreased walking stability, as well as increased plantar pressure and plantar compression time.

Alanyl-glutamine dipeptide is an important component in parenteral nutrition, which can be decomposed into alanine and L-glutamine in vivo. It plays multiple functions including maintaining intestinal barrier, improving immunity, promoting protein synthesis, and regulating the production and release of inflammatory mediators. Substantial clinical evidences have demonstrated its favorable effectiveness and safety. Rational application of alanyl-glutamine dipeptide can reduce postoperative complications, shorten hospital stay and save medical costs. There are still controversies at home and abroad on the applicable population and dosage of alanyl-glutamine dipeptide. Chinese Society of Parenteral and Enteral Nutrition organized China's experts of related disciplines to compile international standards in accordance with the latest guidelines and consensus, so as to achieve the goal of standardized application and patient benefits.

Objective: To investigate the effects of heme oxygenase-1 (HO-1) knockdown on proliferation, invasion and migration of lung adenocarcinoma A549 cells and explore the mechanism. Methods: The expression levels of HO-1 mRNA in human bronchial epithelial cells (HBECs) and human lung cancer cell lines (A549, H1299, H358 and H1993) were detected by real-time quantitative polymerase chain reaction (RT-qPCR), and immunohistochemistry (IHC) was used to detect the expression level of HO-1 in human lung adenocarcinoma specimens. The HO-1 short hairpin RNA (shRNA) was transfected into A549 cells by RNA interference technique. HO-1 stably deleted A549 cells were selected (HO-1 shRNA group) and verified by RT-qPCR and western blot. HO-1 shRNA A549 cells and control shRNA A549 cells were treated with the inducer of autophagy Torin1 or its inhibitor Bafilomycin A1 (Baf A1), respectively. The expressions of autophagic markers LC3B and p62 were determined by western blot. The proliferation, invasion and migration abilities of each group of A549 cells were assessed by cell counting, Transwell and wound healing assays, respectively. Results: The expressions of HO-1 mRNA in lung cancer cell lines (A549, H1299, H358 and H1993) were significantly higher than that of HBECs, and HO-1 upregulated in human lung adenocarcinoma. The expression of p62 protein and the ratio of LC3B-Ⅱ/ LC3B-Ⅰ in no treatment group, Torin1 treatment group and Baf A1 treatment group were significantly higher than those of the corresponding control group (P<0.05). After 11 days of culture, the number of cells in HO-1 shRNA group were 41.8%, 30.4% and 14.0% of the corresponding control group, respectively. The number of lower chamber cells in HO-1 shRNA group were (35.7±2.1), (27.0±1.0) and (38.0±1.0)/field, respectively, which were lower than (66.0±9.2), (39.3±1.2) and (43.0±2.6)/field of the corresponding control group, respectively (P<0.05). The migration distances of HO-1 shRNA group were (7.47±0.91) mm, (4.23±0.82) mm and (5.42±0.24) mm, which were lower than (10.07±1.26) mm, (7.14±0.07) mm and (12.04±0.80) mm of the corresponding control groups, respectively (P<0.05). Conclusion Knockdown of HO-1 inhibits the proliferation, invasion and migration of A549 cells by impeding autophagy.

ObjectiveTo analyze the expression of molecular marker affecting the prognosis of acute myeloid leukemia （AML） patients from bioinformatics database， thus providing an experimental basis for further exploration of a novel molecular marker for the prognosis of AML. MethodsThe prognostic data of 179 AML patients from The Cancer Genome Atlas （TCGA） database were examined for differential gene analysis and survival analysis. The bone marrow samples of 74 healthy individuals （HI） and 542 de novo AML patients in the dataset GSE13159 downloaded from the Gene Expression Omnibus （GEO） database were analyzed to detect the difference in the expression levels of differential target genes. Peripheral blood and bone marrow samples were collected from 18 de novo AML patients and 20 age- and gender-matched healthy controls， and real-time fluorescent quantitative PCR was used to validate the expression levels of the differential genes in the AML patients. ResultsBioinformatics data analysis showed that the optimal cut-off value of Homo sapiens NK2 homeobox 3 （NKX2-3） calculated by R language was 0.051. Survival analysis revealed a statistically poorer overall survival in de novo AML patients with high NKX2-3 expression than in those with low NKX2-3 expression （P = 0.0036）. NKX2-3 was highly expressed in patients with de novo AML than in HI and the difference was statistically significant （P < 0.001）. Real-time fluorescence quantitative PCR verified the expression levels of the NKX2-3 gene in AML patients and confirmed that compared with those in HI， in the de novo AML patients， NKX2-3-1 and NKX2-3-2 were highly expressed and were significantly correlated （P = 0.000， P = 0.000）. ConclusionNKX2-3 is highly expressed in de novo AML patients， and the AML patients with high NKX2-3 expression have poor overal survival. NKX2-3 may be closely related to the clinical outcome and prognosis of AML.
