Through learning philosophy,human beings can overcome the fear of death and gain the wisdom of life.With the rapid development of modem high-tech,some people advocate to pursue the immortality of individual life using science and technology.This is the most restless thoughts,originating from the false belief of dogmatic rationalism:with the development of science and technology,human beings are possible to fully grasp the mysteries of the nature (including human body).In fact,nature as well as human body is always hidden in infinite mystery.The pursuit of immortality is from the pursuit of meaning.Setting up morality,making contribution,and achieving glory by writing are the legitimate ways for human beings to pursuit immortality as cultural animals.One just can pursue immortality in the cultural sense,but cannot pursue the immortality of individual life.

Objective To evaluate the clinical results of phacoemulsification combined with pars plana vitrectomy for eyes with cataract and proliferative diabetic retinopathy. Design Non-controlled retrospective case series study. Participants 123 eyes with proliferative diabetic retinopathy (PDR) and cataract. Methods Phacoemulsification,posterior chamber intraocular lens (PCIOL) implantation combined with pars plana vitrectomy were done in 123 eyes with proliferative diabetic retinopathy (PDR) and cataract. Postoperative vision,number of secondary procedures and surgical complications were analyzed. Main Outcome Measures Postoperative visual improvement and associated complications. Results All 123 eyes underwent combined surgery. The average follow-up was 10 months. 99 eyes (81%) experienced postoperative vision improvement of varying degrees. Vision improved by 2 lines or more in 93 eyes (76%). No apparent corneal edema or corneal decompensation were encountered. One patient with type 1 diabetes developed neovascular glaucoma 6 months after surgery. Retinal detachment occurred in 1 eye and reoperated. Vitreous hemorrhage requiring secondary procedure happened in 4 eyes. All 24 eyes (19%) without vision improvement were found to be with diabetic maculopathy. Conclusions Phacoemulsification combined with pars plana vitrectomy can be used as an effective surgical tool to improve visions in patients with PDR and cataract. Diabetic maculopathy is the major cause of poor visual improvement. (Ophthalmol CHN ,2006,15: 198-201)

Objective The aim of this paper is to develop a holistic mathematical model to quantify the correlation between skin thermal sensation and noxious stimuli,since skin thermal pain is one of the most common problems in everyday life and the understanding of the underlying physical mechanisms is still not clear.Methods The model is developed by considering the biothermomechanical behaviour of skin tissue and by incorporating the current understanding of biophysical and neurophysiological mechanisms of pain sensation.Results The proposed model consisted of three interconnected sub-models: peripheral modulation of noxious stimuli,which converts the energy from a noxious thermal stimulus into electrical energy via nerve impulses;transmission,which transports these neural signals from the site of transduction in the skin to the spinal cord and brain;and modulation and perception in the spinal cord and brain.The model predictions agree well with existing experimental data.Conclusion With this model,a direct relationship has been built between the level of thermal pain sensation and the character of noxious stimuli.

Objective To investigate the role of atrial natriuretic peptide(ANP) and endothelin 1 (ET-1) of newborns with congenital heart failure and its clinical significance.Methods One hundred newborns with congenital heart disease were selected as our subjects.They were divided into 3 groups according to cardiac function grading criteria and that were grade Ⅰ group(30 cases),grade Ⅱ group(40 cases) and grade Ⅲ-Ⅳ group(30 cases).Another 30 normal newborns were served as control group matched with age,gender.ET-1,ANP were detected.Results The levels of ET-1 and ANP in newborns of grade Ⅲ-Ⅳ were (132.35 ±5.26) ng/L and (9.25 ± 2.37) pmol/L,significant higher than that in control group((53.62 ± 3.81) ng/L and (1.15 ±0.09) pmol/L;P ＜0.01).As the severity of the disease in newborns with congenital heart failure,the level of ET-1,ANP were activated more.There was a positive correlation between ET-1 and grade of cardiac function (r =0.35,P ＜ 0.01).Meanwhile,it also showed a positive correlation between ANP and cardiac function (r =0.72,P ＜ 0.01).Conclusion ET-1,ANP in newborns with congenital heart disease are activated with characterized of chronic heart failure,and related to severity of the disease.

Objective To explore the causes and surgical management of acute gangrenous cholecvstitis(AGC)after endoscopic sphincterotomy(EST).Methods Clinical and pathological data of 1066 patients who underwent EST from June 2003 to January 2007 were analyzed retrospectively.ResultsAGC was complicated in 16 patients(16/1066,1.5%),who underwent emergency operations and no death occurred.During the follow-up period of 4 to 36 months,no infection or obstruction was found.Conclusion Difficuitv in EST manipulation and biliary obstrucion might play a leading role in AGC after EST,and early surgical intervention is effective.

Recent studies about the GCT are focusing on searching for new standards and indexes to prognose the biological behavior of the GCT because of the traditional standards and indexes have been realized often not agree with to the clinic. we review the lately research about the biological behavior of the GCT, then analyse and sum up the correlative indexes that could be significant in studying the prognosis of the GCT.

Clinical tutors' personality manifesting during the process of clinical practice and daily communication with medical interns has a series of influences on medical ethics formation of medical interns,including influences of direction,demonstration,contraction,and halo effect.Thus,clinical tutors should pay attention to cultivating a decent moral personality,and hospitals should value the proper combination of moral evaluation and supervision for medical staff in order to achieve the unity of heteronomous morality and self discipline,and effectively promote the formation of decent morality and personality of clinical tutors.
