Objective To prolong the shelf life of RBCs stored at non-4℃, and improve the ability of blood supplying during wartime. Methods 12 bags of packed RBC were collected from 12 volunteers presenting blood, respectively, and each was averagely divided into 5 parts(groups): combination group, new solution group, ammonia group, control group and 4℃ group. The fist 4 groups were stored at room temperature, and were tested for ATP concentration daily. 4℃ group was stored at 4℃, and RBC ATP concentration was measured at the end of its shelf life, which served as a critical ATP concentration. When RBC ATP concentration of the fist 4 groups decreased to the level of critical ATP, the time of preservation was their shelf life. 6 bags of packed RBC were added the same solution as the combination group, and each was averagely divided into 4 parts(groups)after stored at room temperature for 12 days, which were washed for 0, 5,10 and 15min before centrifugation, respectively. The residual ammonia and the recovery ratio of RBC were measured after washing. Results The shelf life of combination group,new solution group,ammonia group and control group was 12,6,6 and 5 days, respectively. The residual ammonia could be effectively cleaned up after either washing 4 times with 5 min balance time or 3 times with 10 or 15 min balance time. The recovery ratio of RBC was 88.5% and 83.1% after washing 3 and 4 times, respectively. Conclusion The combination of new solution and ammonia was a good additive solution for RBC preservation at non-4℃, and the residual ammonia can be cleaned up using normal saline.

Chemokine CXCL9/Mig (monokine induced by IFN-?) belongs to the subfamily of chemotactic cytokines known as CXC-chemokines. In vivo CXCL9 is mainly induced by IFN-? in macrophages and primary glial cells. In vitro, CXCL9 can be secreted by cells such as macrophages, microvascular endothelial cells and neutrophils, in response to the synergy of IFN-? and TLR(toll-like receptor) ligands. CXCL9 is a chemoattractant for activated T lymphocytes, tumor-infiltrating T-lymphocytes, but not for neutrophils or monocytes. The receptor specific for CXCL9 is CXCR3, a G protein-coupled protein which has seven transmembrane domain. The structure and the chemical characterization of CXCL9, as well as its effects on autoimmune deseases, allograft rejection, cancer therapy were reviewed.

OBJECTIVE To summarize the use of intraoperative neuromonitoring system for monitoring and protection of recurrent laryngeal nerve during thyroid surgery. METHODS There were 21 cases in this study, included 5 cases with thyroid cancer, 9 cases with thyroid benign tumor and 7cases with hyperthyroidism. Intraoperative neuromonitoring system includes the host monitor, stimulus detection pin of recurrent laryngeal nerve, special EMG endotracheal intubation tube which contacts vocal cord, grounding conductive circuit electrode, and anti-jamming probe. Operation method: a "three-step method" was adopted. First we revealed the cervical vagus nerve trunk and tested our instruments, and then dissected and protected the recurrent laryngeal nerve, followed by removal of thyroid tissue. RESULTS In all 21 patients, operative side recurrent laryngeal nerve were exposed from lower thyroid blood vessels to the larynx. All patients were phonated as well as before operation, and without drinking cough. CONCLUSION The intraoperative neuromonitoring system can avoid damage of the recurrent laryngeal nerves when we exposed the recurrent laryngeal nerve before resection of the thyroid tissue and tumor.

Objective To observe the postconditioning cardioprotective effects of atorvastatin (ATV) on ischemia-re?perfusion injury in isolated rat heart, and the role of phosphatidylinositol-3-kinase , protein kinase B(PI3K-Akt), mitochon?drial ATP-sensitive potassium (mito-KATP channel) and mitochondrial permeability transition pore (mPTP) thereof. Meth?ods Healthy male Wistar rats were randomly divided into 9 groups:ischemia reperfusion (I/R) control group, atorvastatin postconditioning (ATV) group, ATV plus PI3K inhibitor LY294002 (ATV+LY294002) group, LY294002 group, ATV plus mi?to-KATP channel inhibitor 5-hydroxydecanoate (ATV+5-HD) group, 5-HD group, ATV plus mPTP inhibitor ATR (ATV+ATR) group, ATR group and ethanol group. Model rats were given 30-min ischemia followed by 120-min reperfusion. The myocardial infarction size, hemodynamic parameters, creatine kinase isoenzyme (CK-MB), lactate dehydrogenase (LDH), nic?otinamide adenine dinucleotide (NAD+) and the expression of myocardial protein kinase B (Akt) and myocardial phospho-pro?tein kinase B (p-Akt) were evaluated. Results Compared with the control group, atorvastatin reduced the myocardial in?farction size, CK-MB and LDH(P<0.05), increased NAD+(P<0.05). There were no significant differences in the myocardi?al infarction size, CK-MB, LDH and NAD+between ATV+LY294002 group, ATV+5-HD group and ATV+ATR group. The hemodynamic parameters were improved in ATV group compared with those in control group. Western blot analysis con? firmed the significant phosphorylation of Akt in ATV group, ATV+5-HD group and ATV+ATR group compared with those of control group. There were no significant differences in the phosphorylation of Akt between ATV +LY294002 group, LY294002 group, ATR group and 5-HD group. Conclusion Atorvastatin postconditioning could attenuate the ischemia-re?perfusion injury through activating the PI3K-Akt, promoting mito-KATP channel opening and inhibiting mPTP opening.

OBJECTIVE To investigate the effect of furanodiene(FDE),a diterpene derived from the medicinal plant Zedoary,on apoptosis of human gastric cancer MGC-803 cells induced in vitro. METHODS MGC-803 cells were treated with FDE 46.29~740.74μmol·L-1 for 24,48 and 72 h,and the cell viability was detected with MTT assay. Cell morphology was observed by light microscopy and Hoechst33342 staining. Flow cytometry was used to detect cell apoptotic rate and cell cycle. Rh123 staining and fluorescence probe DCFH-DA were employed to detect the changes in mitochondrial membrane potential (MMP) and reactive oxygen species(ROS). RESULTS MTT Results showed that FDE 46.29-740.74μmol · L-1 exhibited significantly higher cytotoxicity to gastric cancer MGC-803 cells. IC50 for MGC-803 of 24,48 and 72 h treatment was 347.91,257.41 and 101.01μmol·L-1,respectively. Treatment with FDE 92.58-370.32μmol·L-1 for 24 h also caused significant morphological changes in MGC-803 cells. AnnexinⅤ-FITC/PI double staining showed that the apoptotic rate increased after FDE 92.58-370.32μmol·L-1 treatment for 24 h(P<0.05). FDE enabled MGC-803 cell cycle arrest in S phase. DCFH-DA staining showed that FDE resulted in an increase in intracellular ROS levels(P<0.05) when PDE concentration was 370.37μmol·L-1(P<0.05). MMP decreased after FDE treatment when PDE concen?tration was 370.37μmol·L-1(P<0.05). CONCLUSION FDE Possesses potent tumor selected toxicity and can induce apoptosis of MGC-803 cells through cell cycle arresting,which is related to inhibition of DNA biosynthesis.
