ABSTRACT

Objective:To explore the effects of myosteatosis and blood glucose (BG) on postoperative complications in non-diabetic gastric cancer patients receiving supplemental parenteral nutrition (SPN) after gastrectomy.Methods:Patients who underwent radical gastrectomy between March 2017 and June 2021 in the Department of Surgical Oncology, the First Hospital of Lanzhou University were included in this study. Various preoperative inflammatory and nutritional indicators, including skeletal muscle metrics at the third lumbar level on CT, were collected retrospectively. Postoperative BG within 3 days and complications within 30 days were monitored. Patients were divided into two groups according to the presence or absence of myosteatosis (assessed via skeletal muscle density [SMD]) and the differences in postoperative BG and complication incidence were compared. Mediation model was used to analyze the mediating effect of BG in the association between SMD and postoperative complications.Results:A total of 357 patients were included in the study. Compared with the 299(83.8%) patients without myosteatosis , the incidence of hyperglycemia, mean BG, maximal BG, and BG fluctuation while on SPN in the 58(16.2%) patients with myosteatosis were higher, and the comprehensive complication index (CCI) and the incidence of complication were higher ( P<0.05). More importantly, BG showed the mediation effect of -0.0892 in the effect of SMD on CCI ( P<0.05), with the effect size of 19.3%. Conclusion:Myosteatosis and postoperative hyperglycemia are associated with higher incidence of complications, and BG plays an intermediary role in the association between myosteatosis and CCI.

ABSTRACT

The tumor prescriptions contained in Dictionary of Tumor Formulas, Compendium of Good Tumor Formulas, Chinese Pharmacopoeia, Ministry of Health Drug Standards for Chinese Medicine Formulas and National Compilation of Standards for Proprietary Chinese Medicines were selected and organized to construct a database for tumor prescriptions, and the data mining techniques were applied to investigate the prescription regularity of colorectal cancer prescriptions. The formula data were extracted after screening in strict accordance with the inclusion and exclusion criteria, and were then analyzed with Microsoft Excel 2010 for frequency statistics, Apriori block provided by SPSS Clementine 12.0 software for correlation rule analysis, and arules and arulesViz packages in R 4.0.2 software for correlation rule visualization. In addition, SPSS 18.0 software was used for cluster analysis and factor analysis, in which cluster analysis was performed by Ochiai algorithm with bicategorical variables in systematic clustering method and factor analysis was performed mainly with principal component analysis. A total of 285 prescriptions were included in the statistical analysis, and the frequency statistics showed that 43 herbs had been used more than 16 times. The association rules analysis showed that 26 high-frequency me-dicine pair rules were obtained, and the association rules for those dispelling evil spirits, strengthening the body, resolving stasis, dispelling dampness, etc. were visualized. In the cluster analysis, we generated a dendrogram from which 7 groups of traditional Chinese medicines with homogeneity were extracted. 10 common factors were obtained in the factor analysis. The types of herbal medicines involved in the colorectal cancer prescription included anti-cancer antidotes, strengthening and tonifying medicines, blood-regulating medicines, and expectorant medicines, corresponding to the treatment for eliminating evil spirits, strengthening, resolving stasis, and expectorating dampness. The prescriptions for anti-cancer detoxification were normally based on the pairs composed of Scutellaria barbata-Hedyotis diffusa and Sophora flavescens, Sargentodoxa cuneata, S. barbata, often combined with stasis relieving drug and dampness eliminating drug, reflecting the characteristics of treatment for both toxicity and stasis, dampness and toxicity simultaneously. The prescriptions for strengthening the righteousness and tonifying the deficiency were composed of Astragalus membranaceus and Atractylodes macrocephala mainly, exerting the effect of benefiting Qi, strengthening the spleen and drying dampness, tonifying kidney and essence, tonifying blood and invigorating blood. Meanwhile, anti-cancer detoxification medicines shall be reduced as much as possible. The compatibility of the medicines for the intestinal tract reflected the principle of using the right medicine for the right condition and eliminating evil spirits or strengthening the body, as appropriate.

ABSTRACT

Objective To measure the bone mass, the shape of bones and the bone strength through segmentation of the bone cortex in CT images, and to calculate the corresponding parameters in histomorphometry. Methods CT images were first interpreted through the DCMTK to draw information of the corresponding images, then the OpenCV are used for preprocessing on the basis of ROI (range of interest), and the texture features of the image were extracted as the input vector. Results of the manual segmentation were used as the mentor signal to train BP neural network, which were then used for segmenting the bone cortex in a sequence of CT images. Results of the segmentation were further processed and displayed. Results The segmentation efficiency of the bone cortex in CT images through neural network met the needs of the practical application. The separation results showed an obvious shape of the bone cortex with easy distinguishing from the surrounding tissues, which could satisfy the demand of the clinical diagnosis. Conclusions When the texture features of the bone cortex are evident, this method can achieve a more satisfying segmentation effect with smooth contours, high segmentation accuracy and strong adaptability. With less artificial intervention in the process of the image segmentation, this method can be used for batch CT image segmentation of a complete set of the bone cortex. The inadequacy of the method lies in relatively longer training time demanded for the neural network training.

ABSTRACT

Objective To explore the curative effectiveness of transplantation of bone marrow-derived liver stem cells (BDLSCs) transfected with rat interleukin-10 (IL-10) gene in the treatment of liver fibrosis in rats. Methods β2m-/Thy-1+BDLSCs isolated from Wistar rats were transfected with adenovirus-mediated rat IL-10 gene Wistar rats were subcutaneously injected with CCl4 to induce liver fibrosis, and randomly divided into three groups as follows: (1) the model group, infused with 1 ml normal saline (NS); (2) the BDLSC group, infused with NS containing untreated β2m-/Thy-1+BDLSCs (2×105 cells); (3) the IL-10 group, infused with NS containing β2m-/Thy-1+ BDLSCs transfected with IL-10 gene (2×105 cells). Infusion was done via the portal vein. Rats subcutaneously injected with olive oil served as control (the normal group). The BDLCs labeled with diamidine phenylindole dihydrochloride (DAPI) in the liver were localized. Pathological changes and collagen area in liver tissues were observed. Liver function and blood blotting function were tested. Results β2m-/Thy-1+ BDLSCs labeled with DAPI were observed in liver tissues of rats. Significant pathological changes of liver tissues were observed in the model group. Compared with the model group, pathological changes were alleviated to some extent in the BDLSC group. The morphology of liver tissue in the IL-10 group was mostly close to that in the normal group. Collagen deposition of liver tissues was increased obviously in the model group. However, transplantations of untreated and IL-10-transfected BDLSCs both reduced collagen area. Compared with the BDLSC group, collagen deposition was significantly suppressed in the IL-10 group. Transplantation of IL-10-transfected BDLSCs suppressed obviously the levels of ALT, AST, ALP, TBIL, PT and APTT as compared with the model group (P<0. 05). The levels of ALT, TBIL, PT and APTT in the IL-10 group were significantly reduced to the normal levels as compared with those in the BDLSC group (P<0. 05).Conclusions Transplantation of BDLSCs transfected with rat IL-10 gene was effective in treating liver fibrosis in rats. This combined strategy of IL-10 gene and BDLSCs may represent a feasible, effective and safe therapy form for liver fibrosis.
