Objective To investigate the protective effects of mild hypothenmia on myocardium of porcine with septic shock. Method A total of 24 Guishou miniature pigs were randomly(random number) divided into the pre-shock mild hypothermia group, shock mild hypothermia group and shock normothermia control group with 8 in each group. After the anesthesia of pigs, E. coli endotoxin was injected into femoral vein to establish the sepsis model of swine. After modeling, normal saline was continuously administered into femoral vein of pigs in three groups with in-fusion pump at steady speed. In the pre-shock mild hypothermia group,4 ℃ normal saline was used for intravenous injection to produce mild hypothermia before E. eoli endotoxin injection. In the shock mild hypothermia group, 38 ℃ saline was used at first and the 4 ℃ saline was employed after the systolic pressure of mice dropped to 60% of the o-riginal pressure for one hour. In shock normothermia group,38 ℃ saline was used from the beginning to the end of the experiment. The hemodynamics, blood lactate, CtnI, coronary angiography for detecting TIMI flow and the ultra-structural changes under electron microscopy were observed 6 h and 12 h after temperature intervention. Results (1) In pre-shock mild hypothermia group, the findings in all of observation were better than those in shock mild hy-pothermia group and shock normothennia group 6 h and 12 h after temperature intervention (P < 0.01). (2) In shock mild hypothermia group, the CtnI was lower and the ultra-structural changes were less severe than those in shock normothermia group (P < 0.05), but there were no significant differences in blood lactate, TIMI and hemody-namies between shock mild hypotherrnia group and shock normothermia group (P > 0.05). (3) There were no sig-nificant differences in all measurements between shock mild hypothermia group and shock normothennia group after 12 hours later (P > 0.05). Conclusions Mild hypothermia has some protective effects on myocardium of swine with sepsis. If the mild hypothermia is employed before the emergence of shock, the protective effects would be more ef-fective and the cardiac function would maintain at higher efficiency. If the hypothermia is used after the occmTence of shock, it could blunt the cardiac damage and preserve the cardiac function in some extent.

BACKGROUND:Besides drug therapy, regenerative therapy is now a matter of global interest in treating osteoporosis. Therefore, it is also important to find better candidate cels. OBJECTIVE:To cognize the status of drug therapies for osteoporosis and stem cels as regenerative therapy. METHODS:A computer-based search of PubMed was performed by the first author to retrieve articles relevant to stem cel therapy for osteoporosis published from January 2000 to December 2014. The keywords were osteoporosis, drug therapy, bone regenerative medicine, stem cel therapy, which appeared in the title, abstract or keywords, and the relevant references were also looked up. Articles published recently or in authoritative journals were preferred, and finaly 39 articles were included in result analysis. RESULTS AND CONCLUSION:Yoshikazu Mikami and co-workers from Japan found two novel bone formation accelerators, SST-VEDI and SSH-BMI, which provides a new direction for related studies on drug therapy. Due to the osteogenesis ability, lack of ethical controversy and less damage, de-differentiated fat cels and pulp stem cels may be promising candidate cels for bone regeneration medicine.

A 2 L tubular photobioreactor (PBR) was designed, and hydrogen production by Rhodospirillum rubrum uptake hydrogenase deficient mutant in this PBR under artificial illumination condition (including continuous illumination and light/dark cycle condition) and natural day/night cycle was investigated, respectively. Hydrogen production by R. rubrum uptake hydrogenase deficient mutant under artificial illumination lasts five days, and hydrogen yield under continuous illumination and light/dark cycle (12 h:12 h) reaches 5752 mL/PBR ? 158 mL/PBR and 5012 mL/PBR ? 202 mL/PBR, respectively. Under natural day/night cycle, hydrogen production lasts 6~10 days and the maximal hydrogen yield of R. rubrum reaches 2800 mL/PBR with the optimal light intensity of about 30000~40000 Lux. Hydrogen production under natural day/night cycle condition was lower than that under artificial illumination, however, it would be a promising technology of hydrogen production due to low cost and ease of operation of hydrogen production system.
