Neovascular glaucoma is a rare and severe complication of hypoperfusion retinopathy.The appearance of hypoperfu- sion retinopathy complicating neovascular glaucoma in ophthalmolscopy and fundus fluorescein angiography shows a special feature. Neovascular glaucoma occurs when new fibrovascular tissues proliferate onto the chamber angle and obstruct the trabecular meshwork. The stenosis or occlusion of internal carotid artery is the most common reason of hypoperfusion retinopathy in elder people.Early recog- nition and treatment of patients with carotid occlusive diseases may prevent more serious complications.

This paper aimed to analyse and review the literature of diagnosis and treatment of Chinese aphasia at home in recent years. The advanced brain imaging technology and events related potentials, besides the traditional neuropsychological check method, had been much more applicated and studied in the diagnostic research of Chinese aphasia at present, and in the future the check methods of Chinese aphasia showed diversification, systematic and standardized development. A large number of clinical reshearches tended to comprehensive treatment as the main approach for Chinese aphasia in a conclusion.

This article briefly summarized the meaning, category and function of qi, tubes and viscera in human body respectively after combining exploring the theories of traditional Chinese medicine(TCM) and clinical practices. Afterward, we put forward the theory of Qi-Tube-Viscera and elaborated its close relationship with the physiological status of the human, and then we thought the relationships of qi, tube and viscera respectively, at last we draw a conclusion that qi, tube and viscera only came from qi. And the clinical guiding significance of the theory of Qi-Tube-Viscera and itsBalanced steady state, Nature and Man in One, State medicine were narrated to demonstrate that new theory of Qi-Tube-Viscera has high signifance in the theory of TCM and clinical practice.

Objective To investigate the effects of Morusin on cell line proliferation, cell cycle and cell apoptosis of colorectal cancer HCT116 cell;To discuss its mechanism. Methods HCT116 cells were treated with different concentrations of Morusin for 72 h. Cell proliferation was detected by CCK-8 assay, and cell growth inhibition rate and IC50 value were calculated. HCT116 cells were treated with 25.4, 50.8 μmol/L Morusin for 24 h, 48 h and 72 h. Cell morphology was observed under the microscope, and cell proliferation was detected by CCK-8 assay. After HCT116 cell line was treated with 25.4μmol/L Morusin for 24 h, cell cycle phase distribution was detected by flow cytometry and the cell apoptosis was detected by TUNEL assay under the fluorescence microscope. Post-intervention protein expressions were detected by Western Blot. Results The inhibitory effects of Morusin on the proliferation of HCT116 cell line was concentration/time dependent and IC50 value at 72 h was 25.4μmol/L;Morusin induced the cell cycle arrest at G0/G1 phase and G2/M phase, but there was no induction of cell apoptosis;Morusin significantly decreased the expression ofβ-catenin and its target c-Myc, and downregulated the expressions of cyclinD1 and cyclinB1, which were involved in cell cycle regulation. Conclusion Morusin can inhibit HCT116 cell cycle and the proliferation of colorectal cancer cells. Its mechanism might be realized by suppressing the activity ofβ-catenin pathway and reducing the protein expressions of cyclinD1 and cyclinB1.

Objective To investigate the effects of Xiaotan Sanjie Recipe (XTSJR) on the proliferation and apoptosis of colorectal cancer cell;To study its relevant mechanism. Methods The original XTSJR aqueous solution was lyophilized, weighted, and dissolved in cell culture and stored. HCT116 cell line was treated with different concentrations of XTSJR for 72 h, and the cell proliferation was detected by CCK-8 assay. XTSJR treated HCT116 cell line with the concentration of 0.94 mg/mL and 1.88 mg/mL for 24 h, 48 h, 72 h, and the cell proliferation was detected by CCK-8 assay. HCT116 cell line was treated with different concentrations (0.24, 0.47, 0.94, 1.88 mg/mL) of XTSJR for 72 h. The cell apoptosis was detected by TUNEL assay under the fluorescence microscope, and the post-intervention expression of Caspase3 protein was detected by Western blot. Results The inhibitory effects of XTSJR on the proliferation of HCT116 cell line was concentration-time dependent. The IC50 value at 72 h-time point was 0.94 mg/mL. Medicine concentration and the treated time have interactive contribution to the inhibitory effect. XTSJR induced the cell apoptosis. The apoptosis rate increased with the increasing medicine concentration. There was statistically significant difference compared with the control group ( P<0.01). After treatment the expression of Pro-Caspase3 decreased, while the expression Cleaved Caspase3 protein increased. Conclusion XTSJR inhibits the proliferation of HCT116 cell line and induce apoptosis. Its mechanism might be related to the activity of Caspase3 protein.
