1.Medical imaging in the diagnosis of ocular fundus diseases
Chinese Journal of Ocular Fundus Diseases 2011;27(2):109-113
Ophthalmic imaging including radiographic imaging, acoustic imaging and optical imaging,as a branch of medical imaging has developed rapidly. Optical imaging is very suitable for fundus examination because of the physiological characteristics of the eye. Ophthalmoscope and fundus fluorescein angiography are two historical stages of fundus optical imaging, which become an independent new discipline now, including infrared fundus photography, fundus autofluorescence, fundus fluorescein and indocyanine green angiography and optical coherence tomography. Comprehensive optical imaging plays an irreplaceable role in the diagnosis and treatment evaluation of ocular fundus diseases. Appropriate understanding the principles and significance of various optical imaging methods is very important for their clinical applications.
2.A unique inhibitor of fVⅡa/TF: Nematode Anticoagulant Protein c2
Chinese Pharmacological Bulletin 1987;0(02):-
Nematoda anticoagulant protein c2((NAPc2)) is a protein originally isolated from the canine hookworm Ancylostoma caninum.NAPc2 binds to a noncatalytic site on fⅩa then selectively inhibits fVⅡa/TF complex.NAPc2 is proven to be a safe and potent anticoagulant in Phase Ⅰ and Phase Ⅱ clinical trials,and it has prolonged elimination half-life(longer than 50 h).In a word,NAPc2 may play a promising role in the prevention and treatment of thrombosis,disseminated intravascular coagulopathies(DIC) and tumor.

Objective To explore the protective effect of liraglutide ( Li) on the proximal tubular cells ( PTECs) of rats induced by model control. Methods The PTECs of rats were obtained by primary culture and divided into normal control group ( NC) , model control group ( HG) , HG+low-dose Li group, HG+medium-dose Li group, and HG+high-dose Li group ( n-6 in each group) . After 72 h of incubation, the activity of Na+/K+-ATPase in PTECs was measured by the liquid scintillation counter. Protein expression of Toll-like receptor 4 ( TLR4 ) was measured by Western blotting. Interleukin-6 ( IL-6 ) , tumor necrosis factor-α (TNF-α) and plasminogen activator inhibitor-1 (PAI-1) in culture supernatants were measured by the enzyme linked immunosorbent assay (ELISA). Results Compared with NC, activity of Na+/K+-ATPase [(2 737. 88±317. 22)μmol·g-1 ·h-1 ] and the protein expression of TLR4 in PTECs, IL-6, TNF-α and PAI-1 in culture supernatants were significantly increased in HG (P<0. 05, or P<0. 01). Compared with HG, activity of Na+/ K+-ATPase and the protein expression of TLR4 in cells, IL-6, TNF-αand PAI-1 in culture supernatants reduced significantly in HG+medium-or high dose Li groups (P<0. 05, or P<0. 01). Conclusion Liraglutide can inhibit the expression of inflammatory cytokines and stabilize the Na+/ K+-ATPase’ s activity in PTECs in high glucose environment. Therefore, it may play a role in kidney protection.

The original teaching of clinical pharmacy for stomatology course did not let students aware of the importance of drugs in the treatment of oral diseases. The original teaching framework was rearranged:decentralizing knowledge of oral diseased related clinical pharmacy into several mod-ules;setting general knowledge into the oral basic medical module;adding the practice of visiting the pharmacy and manufacturing laboratory. Teaching process was closely combined with clinics and was integrated with disease-centered oral medicine curriculum integration system. Students responded that the teaching effect was better. The rearranged teaching method can enhance students' attention on drug treatment for oral diseases,improve their ability of clinical medication and promote the teaching quality.

Cancer is a leading cause of death worldwide. Although a variety of cancer therapies, such as surgical resection and local ablation, chemoembolization, radiotherapy, and systemic chemotherapy, have developed rapidly in recent years, the curative effect and 5 year-survival rate of cancer remain to be unsatisfactory. In recent years, with the deepening basic research of hydrogen, its role on the treatment of various diseases including cancer has attracted an increased attention. Hydrogen can promote the apoptosis of colon cancer cells, and which combined with 5-fluorouracil has a synergistic effect and can reduce the renal toxicity induced by cisplatin, without affecting its anti-tumor effect. Hydrogen can alleviate the side effects of radiotherapy, significantly improve the quality of life for patients with liver cancer, and does not affect the effect of radiotherapy. Hydrogen application provides a new therapeutic approach to the treatment of cancer. The specific mechanism of hydrogen in cancer treatment needs further study. This article reviewes the research progress of the role of hydrogen on the treatment of cancer, including antioxidant, anti-inflammatory, adjuvant chemoradiotherapy, and the regulation of signaling pathways.

Objective To study the correlation between emotion regulation type and mental quality of young army men.Methods 487 young army men were measured with the Mental Quality Questionnaire of Army men and the questionnaire of army men's emotion regulation types.Results (1)Compared to soldiers,non-commissioned officers were tend to use affective-appeal((16.65±3.57)vs(15.65±3.45),t=2.08,P<0.05).The dimension of altective-appeal was significantly different in service age(F=2.85,P<0.05).The dimension of cognitive-focus had significantly difference between different education levels of soldiers(F=3.94.P<0.01).(2)The dimensions of cognitive-focus(t=4.41,P<0.01) and self-comfort(t=4.44.P<0.01) were significantly different in mental quality level.(3)There was a significant relationship between the army men's emotion regulation types and mental quality(P<0.05).Affective-appeal,behavior-restrain and self-comfort were significantly positive predictions of mental quality,meanwhile cognitive focus was negative.Conclusion There is a significant relationship between the army men's emotion regulation types and mental quality.

The canonical Wnt signaling pathway has been the hot spot in the signaling pathway studies which are related to ovary carcinogenesis in recent years,whose activation may induce the multiplication and self-renewal,survival and metastasis of ovarian cancer stem cells.The target gene mutations of key members in the canonical Wnt pathway and abnormal expresses of negative regulation molecules are closely associated with the occurrence and development of ovarian cancer.Deeply investigating the regulative mechanisms of canonical Wnt signaling pathway in ovarian cancer,and taking this as the therapeutic target to conduct the basic research and preclinical experiment may provide theoretical basis for treating better ovarian cancer patients in clinical practice.
