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.

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.

BACKGROUND:Previous studies have demonstrated that normal rat liver homogenate supernatant can induce human umbilical cord mesenchymal stem cels to differentiate into hepatocyte-like cels with partial hepatocyte functions. However, whether fibrotic liver homogenate supernatant can work or how the inducing effect is remains unclear. OBJECTIVE:To investigate the differentiation potential of human umbilical cord mesenchymal stem cels into hepatocytes under the normal liver and fibrotic liver microenvironment in vitro. METHODS:Liver fibrosis was induced in the SD rats by repeated intraperitoneal injections of 3% thioacetamide at a dose of 200 mg/kg body mass, twice a week for 4 weeks, and then fibrotic liver tissues and normal liver tissues were used to prepare liver homogenate supernatants. Passage 3 human umbilical cord mesenchymal stem cels were used and divided into standard control group (cels were cultured in DMEM/F12 with 10% fetal bovine serum), fibrotic liver homogenate supernatants group (cels were cultured in DMEM/F12 with 10% fetal bovine serum and 50 g/L fibrotic liver homogenate supernatants), normal liver homogenate supernatants group (cels were cultured in DMEM/F12 with 10% fetal bovine serum and 100 g/L normal liver homogenate supernatants). The morphological changes of the cels in each group were recorded under inverted microscope; the protein levels of CK18, AFP, CYP3A4, CYP2E1, CYP2D6 and TPH2 were evaluated using western blot assay. Furthermore, the concentration of albumin in the cels was measured. RESULTS AND CONCLUSION:After a 7-day inducement, the stem cels in liver homogenate supernatants groups lost their fusiform shape and changed into hepatocyte-like cels with the morphous of round shape. Compared with the standard control group, the hepatocyte-like cels in the two liver homogenate supernatants groups exhibited human hepatocyte biomarkers, CK18 and AFP. The standard control group cels could express a little amount of CYP2E1, while cels in the two liver homogenate supernatants groups could express CYP3A4, CYP2E1, CYP2D6, TPH2. Compared with the standard control group, the expression level of CYP2E1 in the two liver homogenate supernatants groups increased significantly (P < 0.01), and however, the relative levels of CYP3A4, CYP2E1, CYP2D6, TPH2 in the two liver homogenate supernatants groups showed no statistical significance (P > 0.05). At the same time, compared with the standard control group, the concentration of albumin in the two liver homogenate supernatants groups markedly increased (P < 0.01), but there was no difference between the two liver homogenate supernatants groups (P > 0.05). Experimental findings demonstrated that both of normal liver tissue and fibrotic liver tissue microenvironments could induce human umbilical cord mesenchymal stem cels to differentiate into hepatocyte-like cels. To achieve the same effect, compared with normal liver tissue, fibrotic liver tissue required lower concentrations, suggesting that fibrotic liver tissue microenvironment may be more conducive to differentiation of umbilical cord mesenchymal stem cels into hepatocytes.

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.
