Background: Radiographic guided percutaneous gastrostomy has become a safe and effective enteral nutrition method for patients who can not eat by mouth. Fluoroscopy, computed tomography (CT) and cone-beam CT have been routinely used clinically. The aim of this study was to compare the advantages and disadvantages of percutaneous gastrostomy using different radiographic guided methods. Methods: We retrospectively analyzed the clinical data of 538 patients undergoing percutaneous gastrostomy in our department. According to the image guidance method used in gastrostomy, the patients were divided into groups A by fluoroscopy guidance, group B by fluoroscopy combined with C-arm CT guidance, and group C with the whole process CT guidance. The gastrostomy success rate, complication rate, procedure time, and patient radiation dose were analyzed in the three groups. Results: Among 538 patients, 534 were successful and the success rates are 94.3%, 99.3%, and 100% in group A, B, and C, respectively (P > 0.05). There were 3 cases occurred postoperative bleeding as serious adverse events and transferred to surgical gastrostomy. The minor complications include local infection, hyperplasia of granulation tissue, tube obstruction or prolapse, and local pain of the ostomy. The minor complication rates were 10.5%, 10.4%, and 7.7% in group A, B, and C, respectively (P > 0.05). The average procedure time was 25.57 ± 5.99 minutes, 29.01 ± 6.63 minutes, and 45.47 ± 8.98 minutes, respectively (χ2 = 87.98, P < 0.001). The average radiation dosage was 27.30 ± 19.27 mGy, 145.07 ± 106.08 mGy, and 2,590.26 ± 1,088.22 mGy, respectively (χ2 = 204.44, P < 0.001). Conclusion: There were no significant differences in the success rates and complication rates of gastrostomy under the three guiding methods. For difficult cases, CT-guided gastrostomy may be a very useful supplemental method.

Background: In mainland China, awareness of disease of elderly cancer patients largely relies on the patients' families. We developed a staged procedure to improve their awareness of disease. Materials and Methods: Participants were 224 elderly cancer patients from 9 leading hospitals across Southern China. A questionnaire was given to the oncologists in charge of each patient to evaluate the interaction between family and patients, patient awareness of their disease and participation in medical decision-making. After first cycles of treatment, increased information of disease was given to patients with cooperation of the family. Then patient awareness of their disease and participation in medical decision-making was documented. Results: Among the 224 cancer elderly patients, 26 (11.6%) made decisions by themselves and 125 (55.8%) delegated their rights of decision-making to their family. Subordinate family members tended to play a passive role in decision-making significantly. Patients participating more in medical decision-making tended to know more about their disease. However, in contrast to the awareness of disease, patient awareness of violation of medical recommendations was reversely associated with their participation in medical decision-making. Improvement in awareness of diagnosis, stages and prognosis was achieved in about 20% elderly cancer patients. About 5% participated more actively in medical decision-making. Conclusions: Chinese elderly cancer patient awareness of disease and participation in medical decision-making is limited and relies on their family status. The staged procedure we developed to improve patient awareness of disease proved effective.
Genetic and Epigenetic Alterations in Bladder Cancer
Hong-Tao Li,Christopher E. Duymich,Daniel J. Weisenberger,Gangning Liang 대한배뇨장애요실금학회 2016 International Neurourology Journal Vol.20 No.S1
Bladder cancer is one of the most common cancers worldwide, with a high rate of recurrence and poor outcomes as a result of relapse. Bladder cancer patients require lifelong invasive monitoring and treatment, making bladder cancer one of the most expensive malignancies. Lines of evidence increasingly point to distinct genetic and epigenetic alteration patterns in bladder cancer, even between the different stages and grades of disease. In addition, genetic and epigenetic alterations have been demonstrated to play important roles during bladder tumorigenesis. This review will focus on bladder cancer-associated genomic and epigenomic alterations, which are common in bladder cancer and provide potential diagnostic markers and therapeutic targets for bladder cancer treatment.

Nanorod hydroxyapatite powders were synthesized using H3PO4 and Ca(OH)2 as precursor materials via a combination of chemical precipitation and microwave techniques route. Effects of various reactive solvent, heating mode of microwave and microwave time on phase stability and morphology of as-prepared hydroxyapatite were investigated based on orthogonal design. The results suggested that when the reactive solvent was pure water, uniform, no agglomerated rod-like hydroxyapatite was formed. Increasing microwave time improved the crystallinity and morphology of rod-like hydroxyapatite, significantly. Heating mode of microwave had a profound influence on the shape, dispersibility and morphology of nanorod hydroxyapatite. Continuously heating by microwave was better for synthesis of nanorod hydroxyapatite. Phase stability of high energy metastable hydroxyapatite brought by microwave route was improved by low temperature presintering.

Sepsis is a systemic inflammatory responsesyndrome caused by severe infections. Astilbin is a dihydroflavonolderivative found in many medicinal and foodplants with multiple pharmacological functions. To investigatethe effects of astilbin on sepsis-induced acute lunginjury (ALI), cecal ligation and puncture was performed onrats to establish a sepsis-induced ALI model; these ratswere then treated with astilbin at different concentrations. Lung injury scores, including lung wet/dry ratio, proteinleakage, myeloperoxidase activity, and inflammatory cellinfiltration were determined to evaluate the effects ofastilbin on sepsis-induced ALI. We found that astilbintreatment significantly attenuates sepsis-induced lunginjury and improves survival rate, lung injury scores, lungwet/dry ratio, protein leakage, myeloperoxidase activity,and inflammatory cell infiltration. Astilbin treatment alsodramatically decreased the production of inflammatorycytokines and chemokines in bronchoalveolar lavage fluid. Further, astilbin treatment inhibited the expression andproduction of macrophage inhibitory factor (MIF), whichinhibits the inflammatory response. Collectively, these datasuggest that astilbin has a protective effect against sepsisinducedALI by inhibiting MIF-mediated inflammatoryresponses. This study provides a molecular basis for astilbinas a new medical treatment for sepsis-induced ALI.

Glycosylation is often used to improve a natural product’s properties such as water solubility, chemical stability, pharmacological potency, and structure diversification. In this study, we studied the enzymatic synthesis of novel isobavachalcone glucosides using a UDP-glycosyltransferase (YjiC) from Bacillus licheniformis DSM-13. The chemical structures of compounds 1 and 2 were elucidated by spectroscopic techniques, including LC–MS, MS, and NMR. Meanwhile, the parameters of glycosylation reaction such as incubation time, UDP-glucose concentration, and pH of buffer were also optimized during this study. Furthermore, the compounds 1 and 2 exhibited weak anti-proliferative activities against five human cancer cell lines, with IC50 values ranging from 58.6 to 86.6 lM.
