1.Research progresses in the distribution of ocular tissue of microRNAs and its relationship with oculopathy
Chinese Journal of Experimental Ophthalmology 2012;(10):956-960
MicroRNAs(miRNAs) are a newly discovered class of small noncoding RNAs that rcgulate gene expression by translational repression or mRNA degradation.It has become evident that miRNAs are involved in many important biological processes,including tissue differentiation and development,showing a tissue specificity and development-stage specificity.In the other hand,miRNAs play critical roles in neovascularization and a variety of pathophysiological processes,such as pathological angiogenesis,oxidative stress response,immune response and inflammation.Currently,miRNAs of the retina,lens and cornea have been established,and they would be potential therapeutic targets in the eye diseases.Here,the distribution of miRNAs in the eye and their role in ocular diseases were summarized.
2.New progress in the surgical treatment of low rectal cancer
International Journal of Surgery 2015;42(5):356-360
Rectal cancer is one of the common malignant tumors in China,and the incidence rate is rising year by year.Comprehensive treatment based on surgical operation is the major treatment of low rectal cancer.The treatment concept requires not only radical resection of tumor,but also preservation of the anal and urogenital function,to improve the quality of patients' life.By improving the accuracy of preoperative staging of rectal cancer,neoadjuvant therapy,and following the principle of total mesorectal excision,patients can benefit in terms of increased resection rate,decreased operation complication incidence,increased sphincter preservation,decreased local recurrence and increased overall survival rate.With the development of medical technology,minimally invasive surgery of low rectal cancer has been developed rapidly.In this paper,new progress in the surgical treatment of low rectal cancer will be reviewed.

4.Pharmacological Treatment Strategies for Alzheimer's Disease.
Journal of the Korean Medical Association 2002;45(4):401-408
Alzheimer's disease(AD) is one of the most common causes of mental deterioration in elderly individuals, accounting for around 45~60% of the overall cases of dementia over 65 years of age. Although there is presently no "cure" for AD, a large number of potential therapeutic interventions have emerged to correct cholinergic dysfunctions. Currently, cholinergic therapy, particularly cholinesterase inhibition, represents the most realistic approach to the symptomatic treatment of AD. Modest efficacy for mild to moderate AD has been shown in well-designed clinical trials for tacrine, donepezil, rivastigmine, and galantimine. Among other treatment options, estrogen replacement therapy in postmenopausal women is under active investigation, but recent studies showed somewhat disappointing results. Epidemiological and clinical data suggest that nonsteroidal anti-inflammatory drugs are beneficial in the treatment and prevention of AD. But prednisone and COX-2 inhibitor, celecoxib showed no clinical benefit in recent studies. Alpha-tocopherol and gingko biloba showed some beneficial effect in delaying the progression of AD and enhancing cognitive functions. Immunization with beta amyloid peptide was considered to be the only method to prevent and halt disease progression in patients with AD. Recently, phase II clinical trial using synthetic beta amyloid peptide (AN-1792) was discontinued because some patients showed neuro-inflammation which may be caused by autoimmune responses.

5.Research on Archive System of Electronic Medical Case
Chinese Medical Equipment Journal 1989;0(01):-
Objective To construct a computerized medical case archive system, which can realize the electronic storage of medical case. Methods Virtual print was used in archive computerized medical cases and electronic signature was used to ensure the legality of the archives. Results The system realized the patient-centered medical information integration and raised the level of medical information storage and management significantly. Conclusion The favorable foundation was established fully in the medical cases archiving system, but the system can be improved in future.
6.Pathological changes and tissue repair methods of hallux valgus
Chinese Journal of Tissue Engineering Research 2009;13(50):9958-9961
The pathological changes of hallux valgus are diversity, including adduct of metatarsus primus, increasing of the intermetatarsal angle between the first and second metatarsal bones, increasing of hallux valgus angle, dislocation of sesamoides, lost of soft tissue balancing. X-ray is the most important method to measure the pathological changes of hallux valgus. The multiformity of hallus valgus pathological changes makes manner of repairing variety. The main methods include operation on soft tissue, osseous surgery, fusion of joint and figuration of joints. The selection of the surgical methods should be individualization according to the idiographic pathological changes of hallux valgus patients.

Objective To study the effects of zinc-metallothionein (ZnMT) on the cadmium-induced oxidative damage of liver and kidney in mice. Methods The model of laboratory animal was established by 14 d-cadmium exposure to Kunming mice. Then the cadmium-poisoning mice were grouped as Cd-ZnMT group and Cd-ZnSO4 group and perfused orally by solution of ZnMT and ZnSO4 for 14 days respectively. The morphological changes of liver and kidney were observed by electron microscope. The contents of malonydiadehyde (MDA), the activities of superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) in supernatant fluid of liver and kidney were determined. Results The decreases of the contents of MDA, the increases of the activities of SOD and GSH-Px in liver and kidney of mice in Cd-ZnMT and Cd-ZnSO4-exposure group were observed compared with those in cadmium-exposure group, the dose-effect relationships were also found. The increases of the activities of SOD and GSH-Px, the decrease of contents of MDA of liver and kidney, were found in Cd-ZnMT-exposure group compared with those of Cd-ZnSO4-exposure group, but without statistical significances. The morphological damages of liver and kidney observed by electron microscope in mice of cadmium-exposure group were more serious than those in mice treated with solution of ZnMT and ZnSO4 after cadmium exposure. Conclusion ZnMT could repair the lipid peroxidative damages in liver and kidney in mice induced by exposure to cadmium in a certain degree.

9.Effects of Exogenous No-DL-3-Hydroxybutyrate and Insulin on Skeletal Muscle Protein Metabolism in Rats after Early Severe Burn Injury
Journal of Third Military Medical University 1984;0(01):-
The effects of exogenous Na-DL-3-hydroxybutyate (3-HOBNa)and insulin(I) on skeletal muscle protein metabolism in rats inflicctcd with 37% TBSA full thickness scalding were studied It was found that the scrum acctoacctatc (AcAc) of the burned animals showed no significant difference from the control on the 4th day postburn,but the free fatty acid (FFA) decreased markedly and the urinary 3 - methylhistididne(3-MH) excretion and the protein de -gradation rate of the soleus muscle of the injured hind limb increased na kedly.Infusion of 3-HOBNa for 3 consecutive days following burns could lower the urinary 3-MH excretion and the protein,degradation rate of the soleus muscle with no significant influence on the skeletal muscle protein anabolism.Moreover,investigations revealed that there was no syncrgistic effect of insulin-kctone body combinalioan on the anti-catabolic capacity in burned rats.
10.Diagnosis of hilar cholangiocarcinoma with multi-slice com-puted tomography
Chinese Journal of Digestive Surgery 2010;9(3):230-231
Hilar cholangiocarcinoma always presents with a mass, thickness of the bile duct wall or nodules in the bile duct. Computed tomography (CT) can demonstrate the above findings with high partial resolution as well as dilation of the intrahepatic bile duct. CT can show the field and the involvement of adjacent vessels on 3D reconstruction images for hilar cholangiocarcinoma spreading along the lumen of the bile duct. CT images can also demonstrate vessel involvement when evaluating the resectability. When combined with 3D reconstruc-tion, the sensitivity and specificity of CT imaging can reach 90.5% and 91.7% , respectively, for detecting vessel involve-ment.
