Photodynamic therapy is the first treatment confirmed to be effective in the treatment of exudative age-related macular degeneration in 2000,which had been introduced to China in the same year.The pathological new vessels were destructed by the singlet oxygen and oxygen free radical released by activated photosensitizer.In the next 12 years,it has been widely applied for the treatment of subfoveal and parafoveal choroidal neovascularization caused by all kinds of chorioretinal diseases.More than a treatment,it also help us to explore the pathogenesis of fundus disease,the capability to embolize the capillaries within the treating area let us not only understand the mechanism of central serous chorioretinopathy and polypoidal choroidal vasculopathy,but also make it a effective cure for them.However,there are still a lot of unsolved questions such as the mechanism of photodynamic therapy,the relationship with human genomic difference,and even the development of angiogenesis.Besides with the more novel medications and strategies available,we also face the appropriate application for indications,selection of combined therapy and optimization of treatment regimens.Further investigations about the photodynamic therapy and disease and their relations from both basic and clinical study will guide us the treatment in clinic and also reveal the truth of related fundus diseases deep under the surface.

Effects of temperature and anesthesia on various excitability indexes of sciatic—peronael nerve were observed in toads. The results show that standard electrical quantity(a) changes regularly with the change of excitability. The higher excitability, the less the "a" value. But "b" in Weiss's fomula, chronaxie (Chr), rheobase (Rh), and intensity-duration curve do not indicate excitability. The time constant (RC)of the cell membrane is not related to the changes of excitability. Thus, "a" is an actual index of measuring excitability.

Colorectal cancer(CRC) is one of the most common tumors with a high prevalence of cancer-related morbidity and mortality.Several environmental factors,especially dietary factors,can affect the initiation and development of CRC.Recent studies have shown that adjusting nutrition components in diet,such as folate,calcium,vitamin D,selenium and fibre,may help to prevent the development of CRC.The objective of article is to review mechanisms of these nutritional components in the process of preventing CRC.

The problems and causes about public hospitals regulation were analyzed based on the theory of regulation incentive using the model of principal-agent.Establishing the independent regulation institution and designing the incentive compatibility system between the government and public hospitals were the strategies.All of the reform practices should be implemented to improve the public welfare and efficiency of public hospitals.

Objective To understand Parkinson disease (PD) medication compliance, and analyze its main influencing factors. Methods The questionnaire method was adopted to survey 130 cases of Parkinson disease patients general information, disease, drug, psychological status, social support and so on. Results The two average score of Parkinson patients medication compliance were (2.36 ± 1.16) points and (9.96 ± 2.60) points. Its influencing factors had personal monthly income, medication concept, PD drug adverse reaction,social support, mental state and anxiety disorder. Conclusions Parkinson patients medication compliance behavior overall is good, but these patients who can be in strict accordance with the doctor′s advice has very few. And the influencing factors are in the majority. According to the influencing factors of medication adherence, medical staff should implement targeted medication guide, in order to improve the medication complianceand their quality of life.
