Objective To study the expression of CDK4 andβ-Catenin and their relevance in glioma. Methods We used immunohistochemistry to detect the expression of CDK4 andβ-Catenin in forty-five glio-ma tissues and eight normal tissues.According to the classification standard of WHO in 2000 classify and grade the tissues.Results There were significant differences of CDK4 andβ-Catenin expressions between normal tis-sues and glioma tissues(P<0.01).The expression of CDK4 and β-Catenin had positive correlation with the pathological grades of glioma and histological type and increased(P <0.05).Furthermore,the expression of CDK4 was positively correlated with the expression ofβ-Catenin in glioma(r=0.52,P<0.01).Conclusion The increased expression of CDK4 andβ-Catenin may have correlation with malignant change of glioma and oc-curance of glioblastoma,and their combination is expected to become an important indicator in assessing malignant glioma.

Objective To study the cytogenetic changes in HPV-immortalized cells(SHEE)for further investigating the esophageal carcinogenesis. Methods Giemsa staining was used to show the modal number of chromosomes.G-banding was done to observe the chromosomal aberrations.Fluorescence in situ hybridization(FISH)of the interphase nuclei with the centromere probes of chromosome 1,7 and 8 were performed to determine the numerical abnormalities. Results The modal numbers at passage 10 and 20 were 58-63 and 57-64, respectively.Passage 61 had a bimodal distribution 58-61 and 63-65.The structural aberrations could almost be found in all of karyotypes.The following structural aberrations were identified:1.del(1)(q12);2.del(1)(p32);3.der(4),t(4;?)(q31;?);4.der(5),t(5:?)(q31;?).FISH results showed that trisomy 1 and tetrasomy 7 markedly increased with the increase of passages and disomy 8 kept in faint change in all passages.Conclusion The modal number moved right slowly in the graph of the modal distribution and the increases of chromosomal numbers were in imbalance with increases of passages of SHEE.The structural aberrations of chromosome were found in most of karyotypes.Our results suggest that the cell immortalization is a multistep process involved in the multiple chromosomes.;

This study was aimed to discover core agent for the treatment of ulcerative colitis and explore the medication rules . A total of 525 ulcerative colitis medical records in the Jiangsu Province Hospital of TCM were selected from 2009 to 2013 . The records were input into the structured information acquisition system of clinical diagnosis and treatment . The complex network analysis was used to analyze core drugs of prescription and drug compatibility after data mining and rule processing . The results showed that the core drugs are Diyu , Huanglian, Muxiang, Baishao, Xianhecao, Danggui, Chaobaizhu, Huangqin, Zicao, Yiyiren, Fuling, Shanyao. It was concluded that data mining can be an objective method in the analysis of core drugs and compatibility in the treatment of ulcerative colitis. It can also be used to guide the clinical prescription medication.

Objective:To evaluate the clinical efficacy of individualized thrombolysis-assisted comprehensive intervention for deep vein thrombosis (DVT) in the lower limbs.Methods:This study included 32 patients with acute lower limb DVT diagnosed by angiography who received treatment at the Jianhu Clinical Medical College of Yangzhou University from March 2012 to November 2021. These patients first received implantation of an inferior vena cava filter. Then they were divided into a control group and an observation group based on treatment methods. The control group received thrombolytic catheterization and a routine infusion of urokinase. In the observation group, balloon dilation was performed first, and a large lumen catheter was used to draw blood clots. Subsequently, urokinase at a dose based on fibrinogen measurement was injected through a thrombolytic catheter. Swelling reduction, venous patency, and complications of the affected limbs were monitored.Results:In the control group, the difference in thigh circumference before treatment was (4.65 ± 1.06) cm, and after treatment, it was (2.76 ± 1.25) cm. In the observation group, the difference in thigh circumference before treatment was (4.73 ± 1.03) cm, and it was (1.40 ± 0.83) cm after treatment. In the control group, the difference in calf circumference before treatment was (2.24 ± 0.90) cm, and it was (1.56 ± 0.86) cm after treatment. In the observation group, the difference in calf circumference before treatment was (2.40 ± 0.83) cm, and it was (0.80 ± 0.73) cm after treatment. After treatment, the differences in thigh circumference and calf circumference between the healthy and affected sides were statistically significant ( t = 3.58, 2.67, both P < 0.05). After treatment, there was a significant difference in venous patency between the control and observation groups (34.02% [33/97] vs. 68.18% [60/88], t = 3.44, P < 0.05). After 12 months of follow-up, the Villalta scale score, which was used to evaluate post-thrombotic syndrome, was (9.23 ± 4.07) points in the control group, which was significantly different from (5.73 ± 3.39) points in the observation group ( t = 2.62, P < 0.05). Conclusion:Individualized thrombolysis-assisted comprehensive intervention is highly effective in the treatment of DVT in the lower limbs and results in few complications.

Extended circulation of anticancer nanodrugs in blood stream is essential for their clinical applications. However, administered nanoparticles are rapidly sequestered and cleared by cells of the mononuclear phagocyte system (MPS). In this study, we developed a biomimetic nanosystem that is able to efficiently escape MPS and target tumor tissues. The fabricated nanoparticles (TM-CQ/NPs) were coated with fibroblast cell membrane expressing tumor necrosis factor (TNF)-related apoptosis inducing ligand (TRAIL). Coating with this functionalized membrane reduced the endocytosis of nanoparticles by macrophages, but increased the nanoparticle uptake in tumor cells. Importantly, this membrane coating specifically induced tumor cell apoptosis via the interaction of TRAIL and its cognate death receptors. Meanwhile, the encapsulated chloroquine (CQ) further suppressed the uptake of nanoparticles by macrophages, and synergized with TRAIL to induce tumor cell apoptosis. The vigorous antitumor efficacy in two mice tumor models confirmed our nanosystem was an effective approach to address the MPS challenge for cancer therapy. Together, our TM-CQ/NPs nanosystem provides a feasible approach to precisely target tumor tissues and improve anticancer efficacy.
