Diabetic ulcer (DU), one of the common and serious complications in patients with diabetes mellitus, often leads to infection, necrosis and amputation, and has a long and costly treatment period. Because of DU's unclear healing mechanism and the difficulty of delayed healing, its treatment and management have been a major challenge in clinical medicine. In recent years, the potential role of mitochondrial autophagy in DU has become a research hotspot with the in-depth study of mitochondrial autophagy mechanism. Previous studies have shown that mitochondrial autophagy is an important intracellular self-repair mechanism that plays a crucial role in maintaining cellular health and functional stability. During the development of DU, mitochondrial autophagy plays multiple roles in attenuating oxidative stress and inflammatory responses, maintaining mitochondrial functional homeostasis, influencing cell proliferation and repair capacity during DU healing, promoting DU healing, and enhancing antimicrobial capacity. In this paper, we illustrate the multiple roles played by mitochondrial autophagy in DU prevention and treatment, as well as the potential applications of mitochondrial autophagy in DU therapy. It is expected to provide a basis for the clinical application of mitochondrial autophagy in DU treatment, and provide more effective strategies and solutions for the treatment of DU.

Objective：This study was designed to summarize the clinical characteristics, biological behavior, and treatment results of acinic cell carcinoma of parotid. Method： Twenty nine cases of acinic cell carcinoma of parotid were collected to make clinical analysis. Results： The clinical feature of acinic cell carcinoma of parotid were observed as following： the incidence of male and female was equal and happen in any age group. The tumor usual located at superficial lobe of parotid, and growth slowly. The course was long with a mean of 5 years. The incidence of cervical lymph node metastasis was 17.2％ and distant metastasis was much less, the local recurrence rate was 20.7％ and the prognosis was relatively better. The survival rates of 3 year,5 year,10 year were 82.7％ ,80％ , and 76.9％ ,respectively. Conclusion： The incidence of acinic cell carcinoma of parotid is low, and acinic cell carcinoma of parotid could be considered as lower malignant tumor. Radical surgical ressection is the most common modality for its treatment, while larger lesion or recurrent cases may receive postoperative radiotherapy so as to decrease local recurrence.

OBJECTIVETo investigate the influence of pleiotrophin (PTN) on the growth of rat hepatocytes.

METHODSPrimary rat hepatocytes were isolated from male Sprague-Dawley rats and divided into three groups: group A (negative control), cultivated in normal culture medium; group B (positive control), cultivated with culture medium supplemented with supernatant from the embryonic fibroblast 3T3 cell line; group C (experimental), cultivated with culture medium supplemented with human recombinant (hr) PTN (100 ng/ml). The hepatocytes' growth rate and level of secreted albumin (ALB) were evaluated by microscopy and biochemical assay, respectively. Significance of between-group differences were assessed by one-way ANOVA, and pairwise comparisons were performed by the least significant difference test.

RESULTSThe growth rates of hepatocytes in groups A, B and C were 2.800+/-0.084%, 4.300+/-0.132% and 3.800+/-0.053%, respectively. The growth rate of group B was significantly higher than the other two groups (F = 333.735, P less than 0.05). For all groups, the highest levels of secreted ALB were detected between the second and sixth day of culture, with g/L concentrations at day 2, 4 and 6 of: group A, 0.550+/-0.010, 0.900+/-0.030 and 0.300+/-0.040; group B, 0.900+/-0.030, 1.300+/-0.020 and 1.400+/-0.030; group C, 0.900+/-0.010, 1.160+/-0.010 and 0.700+/-0.050. The secreted ALB of group B was significantly higher than that of the other two groups (F = 651.355, 338.831 and 863.205, P less than 0.05 ).

CONCLUSIONPTN can benefit in vitro culturing of rat hepatocytes by stimulating growth and enhancing their ability to secrete albumin.

This paper presents a computer-aided diagnosis method for prostate cancer detection using Trans-rectal ultrasound(TRUS) images. Firstly, statistical texture analysis is implemented in every ROI in segmented prostate images. From each ROI, grey level difference vector features, edge-frequency features and texture features in frequency domain are constructed. Then, the number of features is reduced using ANOVA statistics to select the optimal feature subset. Finally, SVM is applied to the selected subset for detecting the cancer regions. Experimental results show that the proposed algorithm can recognize and detect the cancer images effectively so as to supply essential information for a diagnosis.

In this paper, we propose that, the need of the costly re-initialization procedure can be completely eliminated by using the variation formulation, thus increasing the speed of computing operations. The edge detecting function in the geodesic active contour model is improved by incorporating a prior knowledge. The accuracy of the segmentation algorithm can be enhanced by using the minimal variance. Experimental results show that the proposed algorithm can segment the prostate ultrasound images effectively and avoid the problem of contour leakage.
