The natural process of life and death has been profoundly and widely involved and increasingly manipulated by the fast developed technology of life science,which could change the human beings' state of life as well as the state of death.Thus,human beings are motivated to think multidimensionally on life and death from the perspective of science,such as the weakening of sacredness of life,the technology employed in life,the socialization of lifestyles,the exploration of the nature of death,the pluralism of different ways of death and the systematization in the education of death.These considerations will no doubt contribute to the mutual promotion of the development of morality and the advancement of life science technology.

Objective To study the recent clinical efficacy of compound matrine injections combined with three-dimensional conformal intensity modulated radiotherapy in the treatment of locally advanced pancreatic cancer.Methods 48 cases of untreated locally advanced pancreatic cancer were randomly divided into treatment group (compound matrine injections combined with three-dimensional conformal intensity modulated radiotherapy) and control group (three-dimensional conformal intensity modulated radiationtherapy),there were 24 cases in each group.Three-dimensional conformal intensity modulated radiation therapy used 95 ％ isodose coverage PTV.Using 6 MV X-ray irradiation,2 Gy/day,5 times/week,the total radiation dose was 50 Gy/25 times/5 weeks to complete.Treatment group:one week before treatment infusion of compound matrine injections 20 ml/time,l/d,21-day was one cycle.Control group:simple intensity modulated radiotherapy.Results After treatment,the clinical benefit response rate of the treatment group was 87.5 ％ (21/24),the control group was 70.83 ％ (17/24),the difference was statistically significant (P =0.045).Term efficacy rate of the treatment group was 79.17 ％ (19/24),the control group was 50.00 ％ (12/24),the difference was statistically significant (P =0.035).Adverse reactions were hematologic toxicity,leukopenia occurred in the treatment group was 16.67 ％ (4/24),but the control group was 45.83 ％ (11/24),the difference was statistically significant (P =0.029).Conclusion The effects of compound matrine injections combined with three-dimensional conformal intensity modulated radiotherapy for locally advanced pancreatic cancer are good,they can relieve pain,improve short-term efficacy,reduc side effects,and improve the quality of life.

Objective: To compare short-term efficacy of enhanced phase-I cardiac rehabilitation and ordinary phase-Ⅰ cardiac rehabilitation in patients after coronary artery bypass grafting (CABG). Methods: A total of 254 patients received CABG in our hospital from 2015-07 to 2015-10 were enrolled including 196 male and 58 female at the mean age of (59.92±7.80) years. Relevant health education was conducted and echocardiography, emotion, grip strength were assessed before operation. Based on personal aspiration, the patients were assigned to 2 groups at the 1st day after CABG: Enhanced phase-I cardiac rehabilitation (Enhanced) group, the patients received every day one to one training by physical therapist for 7 days and Ordinary phase-I cardiac rehabilitation (Ordinary) group, the patients received unified instruction by physical therapist prior operation. Relevant parameters were compared between 2 groups at 1 week post-operation which were mainly focused on left ventricular ejection fraction (LVEF), emotional assessment as health questionnaire 9-items (PHQ-9), generalized anxiety disorder 7-items (GAD-7) and grip strength. Results: Before operation: LVEF, PHQ-9 scores, GAD-7 scores and grip strength were similar between 2 groups.1 week post-operation: compared with Ordinary group, Enhanced group had the higher LVEF (62.88±5.21) % vs (59.00±9.83) %, P<0.05; Enhanced group showed slightly lower PHQ-9, GAD-7 scores and slightly higher grip strength without statistic meaning. Conclusion: Enhanced phase-I cardiac rehabilitation presented slight superiority as improved LVEF which implied that even 1 week specific training may benefit CABG patients.

· AIM: To evaluate the safety of eye anterior tissue when plasmin (Pm) and hyaluronidase (HS) are injected into pigs'vitreouses to induce posterior vitreous detachment(PVD).· METHODS: 15 pigs without ocular diseases were randomly assigned to groups A,B,C (5 in each group). For each pig, one eye was experimental, the other eye was control. The experimental eye received intravitreal injection with enzyme:group A: 50U(0.1mL) HS; group B: 0.5U(0.1mL) Pm; group C: 0.5U(0.05mL) Pm combined with 50U(0.05mL) HS; while the control eye received intravitreal injection with equivalent dose of balanced salt solution (BSS). Postoperative reactions in the eyes were carefully observed by clinical examinations such as slit-lamp microscopy and direct and indirect ophthalmoscopy and measurement of intraocular pressure (IOP). Eyeballs were extirpated 7 days after the operation and histological examination was carried out. The corneas and irises were observed under light microscope (LM). The epithelia of ciliary bodies and lens were studied with transmission electron microscope (TEM).· RESULTS: In all experimental eyes and control eyes of group A, B and C, histological examination showed: under LM ,the corneas and irises of experimental eyes had no histological abnormality in structure; Under TEM, epithelial cells of ciliary bodies and the lens were tightly arrayed with clear cellular boundaries, clear intracellular structure, intact cell membranes, and intact nuclei; There was no significant difference in the clinical examinations and in the change of IOP between preoperation and postoperation, between the experimental group and the control group.· CONCLUSION: With 0.5U Pm and HS 50U injected into pigs' vitreouses to induce PVD, alone or combined with two enzymes, evaluation revealed no evidence of toxicity on the eye anterior tissue. The dosage was proved to be safe for eye anterior tissue.

Depression, a seriously harmful disease to peoples ’ physical and mental health , is prevailing world-wide.But the etiology and pathological mechanism is still not fully uncovered .With the development of social economy and the pace of life speeding up , increasing pressure and vulnerable emotion cause depression incidence increased rapidly .For the further research on depression , study of depression mechanism and antidepressant drugs highly depends on effective ani -mal models .The degree of similarity of animal models to human disease status and the accuracy and reliability of evaluation methods of animal models directly influence the value of the resuts of experiments .In this article we introduce the common-ly used animal models of depression , the evaluation indicators at organism , organ, and molecular levels , and to provide theoretical references for the further studies on depression .

By using single spleen colony transplantation technique and sex chromosome typing as natural cytogenetic markers, we have been able to demonstrate that most spleen colony forming cells in the adult bone marrow or in foetal liver of inbred LACA or C57 mice possess the potential of re-establishment of myeloid and lymphoid lines of cells in lethally irradiated mice. However, most of the spleen colony forming cells in the peripheral [blood of normal mice possess weak or no potentiality to proliferate or re-establish hemopoiesis in lethally irradiated mice. Our results support the notion that the CFU-S population in mice is heterogeneous.From the nature of colony forming cells in the peripheral blood of normal mice, we are convinced that the assessment of CFU-S content relying upon the spleen colonies as the unique sign to indicate the self-renewal ability of a spleen colony forming cell is by no means valid inasmuch as some plu-ripotent . hemopoietic progenitors derived from pluripotent hemopoietic stem cells may have the same ability to form colonies in vivo.
