ObjectiveTo analyze the dead reasons in treatment of acute myocardial infarction (AMI) by emergent percutaneous coronary intervention (EPCI) during perioperation. Methods The clinical characteristics of the dead patients,results of EPCI and reasons of death were retrospectively analyzed in 473 patients with AMI who received EPCI treatment during March 2004 to March 2011. ResultsAmong the 18 cases(3.8％)dead patients,there were 8 case with three-vessel lesions,5 cases with two-vessel lesions, 2 cases with single vessel lesion and 3 cases with left main lesion. Nine patients were accompanied with hypertensions,5 cases with diabetes mellitus, 1 case with old myocardial infarction, 2 cases with old cerebral infarction, 1 case with chronic obstructive pulmonary disease complicated by severe pneumonia, and 1 case with chronic renal insufficiency. Nine patients died of cardiogenic shocks , 4 cases (22. 2％) of heart ruptures, 2 cases (11.1％) of noreflow,1 case (5.6％) of massive hemorrhage of the upper alimentary tract, 1 case (5.6％) of respiratory failure and 1 cases (5.6％) of refractory ventricular fibrillation.ConclusionsPrimary reasons for perioperative death were cardiac shock and heart rupture in treatment of acute myocardial infarction by EPCI. Multi-vessel lesion, complications with hypertensions and diabetes mellitus may serve as succumbed factors of death.

Objective To assess the risk of malnutrition in elder home-care patients through mini nutritional assessment (MNA) and study the correlations between total MNA score and 18 individual questions in this patient group.Methods In May 2011,62 elder home-care patients from our center answered the MNA questionnaire.And the results were used to analyze the correlations between total MNA score and individual questions and the correlations among MNA classifications and body mass index(BMI),mid-arm muscle circumference (MAMC) and calf circunference (CC).Results According to MNA,18％ were malnourished ( 11/62 ),47％ at risk of malnutrition ( 29/62 ) and 35％ well-nourished ( 22/62 ) ; BMI,independence,mobility,neuropsychological problems,ingesting method,MAMC,CC and selfperceived nutritional status,self-perceived health status showed strong correlations with total MNA score (0.601,0.600,0.666,0.611,0.627,0.618,0.726,0.612,0.672,P ＜0.05).And weight loss within a month,number of daily meals and intake of drinks showed weak correlations with total MNA score (0.35,0.319,0.288,P ＜ 0.05 ).Positive correlations existed among MNA classifications and BMI,MAMC,CC (15.45,19.85,31.89,P＜0.05).Conclusions The elder home-care patients have a high risk for malnutrition.Half of 18 individual questions are strongly correlated with total MNA score in this patient group.

Objective:To investigate the expressions and significance of tyrosine kinase receptor EphA2 and its ligand ephrinA1 in human malignant gliomas and their correlation with tumor angiogenesis. Methods:The expressions of EphA2, ephrinA1, and CD105-stained microvessel density (MVD) were detected via immunohistochemical assay in 62 glioma tissues and 8 normal brain tissues. The correlation between EphA2 and ephrinA1 expression and microvessel counts in the glioma tissues were assessed. Results:Immunohistochemical staining results revealed that variable levels of EphA2 and MVD expression were significantly higher than that of the normal brain samples. Statistical difference was observed in EphA2 and MVD expressions between human gliomas and normal brain samples (P<0.01). The positive rate of EphA2 and MVD expressions was significantly higher in high-grade gliomas (WHO III-IV) than that in low-grade gliomas (WHO I-II) (P<0.01). EphrinA1 was expressed at low levels in most malignant gliomas, and the increased ephrinA1 expression was associated with lower-grade histology. MVD was significantly positively correlated with EphA2 expression (r=0.713, P<0.01) and significantly negatively correlated with ephrinA1 expression (r=-0. 772, P<0.01). EphA2 was significantly negatively correlated with ephrinA1 expression (r=-0.912, P<0.01). Conclusion:Specifically over-expressed EphA2 and its low-expressed ligand ephrinA1 in malignant gliomas may be closely correlated with the invasion and malignant degree of gliomas. Cooperation is involved in the angiogenesis and has an important function in the initiation and progression of gliomas.

Objective:To identify differentially expressed proteins related with malignant transformation of esophageal squamous cell carcinoma (ESCC) using proteomic analysis. Methods:Two-dimensional gel electrophoresis (2-DE) and matrix-assisted laser desorption/ionization timE-of flight mass spectrometry (MALDI-TOF-MS) in combination with protein database searching were used to determine and identify differentially expressed proteins in esophageal cancer cell lines (EC1, EC18, and EC109) and immortal cell line (NECA-E6E7-hTERT). Western blotting and immunocytochemistry were used to verify the differential expression of annexin 2 in esophageal cancer cell lines and immortal cell line (NECA-E6E7-hTERT). Real-time fluorogentic quantitative PCR(RFQ-PCR) was performed to analyze the expression level of annexin A2 mRNA.Results: A total of 15 differentially expressed proteins were identified with more than 5 folds difference. Among them three proteins were down-regulated and 12 proteins were up-regulated. Western blotting and immunocytochemical analysis verified the down-regulation of annexin A2 protein in ESCC cell lines. However, differential expression pattern of annexin A2 mRNA was not consistant with its protein expression in ESCC cell lines and immortal cell line (NECA-E6E7-hTERT). Conclusion:The findings provide important clues for identifying the candidate biomarkers for high-risk population screening and early diagnosis of ESCC. Post-translative regulation/modification contributes to the down-regulation of annexin A2 protein.

BACKGROUND:Currently, neural stem celltransplantation can be performed through three main approaches:local lesions, blood circulation, and cerebrospinal fluid.
OBJECTIVE:To review the transplantation of neural stem cells or neural precursor cells via the cerebrospinal fluid in the treatment of central nervous system diseases.
METHODS:A computer-based search of PubMed and CHKD databases was performed to retrieve articles concerning transplantation of neural stem cells via the cerebrospinal fluid, and its application and therapeutic mechanism in the treatment of central nervous system diseases in both animal experiment and clinic study published from 2000 to 2009.
RESULTS AND CONCLUSION:It is suitable for neural stem cellsurvival, proliferation, and differentiation in the cerebrospinal fluid. Transplantation of neural stem cells via the cerebrospinal fluid is effective and feasible to treat central nervous system diseases. However, some problems have not been solved, such as the source of neural stem cells, the optimal time window and celldose, the safety and the long-term effect. Further studies are needed to pave the way for the intrathecal injection of neural stem cells in the treatment of central nervous system diseases.

Objective To investigate the reasons of HOXA5 overexpression in GBM and the molecular mechanism of miR-128-3p regulating the proliferation, invasion and apoptosis of glioblastoma multiforme. Methods After increasing and decreasing miR-128-3p expression in U87 cell lines by lentivirus transfection, the changes of HOXA5 expression were detected by Western blot, to explore the correlation between miR-128-3p and HOXA5 in GBM. The dual-luciferase reporter tests were performed to detect the target interaction of miR-128-3p with HOXA5. Through CCK-8 test, Transwell test, flow cytometric assay and tumor cell xenograft in nude mice, we verified molecular mechanism of miR-128-3p regulating the proliferation, invasion and apoptosis of GBM in vitro and in vivo. Results The expression level of HOXA5 was decreased in U87 cell line after miR-128-3p upregulation. In addition, the expression level of HOXA5 was increased in U87 cell line after miR-128-3p downregulation (P < 0.05). The expression level of HOXA5 was correlated negatively with the expression of miR-128-3p in U87 cell lines. MiR-128-3p targetedly interacted with 3'UTR of HOXA5 and inhibited the expression of HOXA5. The proliferation, invasion and anti-apoptosis of U87 cells were significantly decreased in the miR-128-3p+control group. Conclusion MiR-128-3p regulates negatively the proliferation, invasion and anti-apoptosis of GBM cells by targeting HOXA5. The overexpression of HOXA5 is induced by downregulation of miR-128-3p in GBM.

Objective To investigate the molecular mechanism of SNHG5 regulating the proliferation, invasion and apoptosis of glioblastoma multiforme (GBM) cells by targeting miR-421. Methods Real-time quantitative PCR test was performed to detect the expression levels of SNHG5 and miR-421 in 31 cases of GBM tissue samples and 32 cases of normal brain tissue samples. After increasing or decreasing SNHG5 expression in U87 cell lines by lentivirus or plasmid transfection, the changes of miR-421 expression were measured by real-time quantitative PCR, to explore the correlation between SNHG5 and miR-421 in GBM. The dual-luciferase reporter test was performed to explore the target interaction of SNHG5 and miR-421. The plasmids with low expression of SNHG5 and miR-421 were cotransfected into U87 cells for the rescue experiment. CCK-8 test, Transwell test, flow cytometry and tumor cell xenograft in nude mice were used to verify molecular mechanism of SNHG5 regulating the proliferation, invasion and apoptosis of GBM in vitro and vivo. Results The expression level of miR-421 was decreased in U87 cell line after SNHG5 upregulation. In addition, the expression level of miR-421 was increased in U87 cell line after SNHG5 downregulation (P < 0.05). The expression level of SNHG5 was correlated negatively with the expression of miR-421 in GBM and U87 cell line. The result of luciferase reporter tests indicated SNHG5 targetedly interacted with miR-421. Rescue experiment results showed that compared with si-SNHG5+miR-421-inhibitor group, the proliferation, invasion and anti-apoptosis ability of U87 cells were significantly inhibited in the si-SNHG5+control-inhibitor group, the expression levels of BAX and p21 were significantly higher, the expression levels of CyclinD1 and Bcl-2 were lower remarkably (P < 0.05). Conclusion SNHG5 promotes the proliferation, invasion and anti-apoptosis of GBM by targeting miR-421 and regulating the expression of CyclinD1, p21, BAX and Bcl-2. Downregulation of miR-421 is related to SNHG5 overexpression in GBM.

【Objective】 To retrospectively analyze the indexes of autologous blood transfusion during heart valve replacement, in order to provide reference for allogeneic blood transfusion during heart valve replacement surgery under direct vision. 【Methods】 The data of 180 patients who underwent heart valve replacement in our hospital from January 2020 to December 2021 were analyzed retrospectively. The patients were divided into allogeneic and non-allogeneic blood transfusion group based on whether allogeneic blood was transfused during the operation, and the general data and 24 hours pre- and post-operative clinical examination indexes were compared. 【Results】 Multivariate logistic regression analysis showed that age (OR=1.110, 95% CI: 1.058-1.165, P<0.05) and intraoperative cardiopulmonary bypass time (OR=1.062, 95% CI: 1.038-1.086, P<0.05) were risk factors for allogeneic blood transfusion, and preoperative Hb content (OR=0.910, 95%CI: 0.868-0.953, P<0.05) was a protective factor. The RBC count(4.16±0.73 vs 4.52±0.71)×10¹²/L and Hb(120.94±17.97 vs 136.57±19.33) g/L at 24 hours preoperative in the allogeneic transfusion group were lower than those in the non-allogeneic transfusion group, and the RBC(3.51±0.53 vs 4.13±0.78)×10¹²/L, Hb(114.15±11.68 vs 124.79±14.96)g/L and platelet count(124.28±32.11 vs 148.29±26.62)×10⁹/L at 24 hours postoperative were significantly lower than those in the non-allogeneic transfusion group (P<0.05). 【Conclusion】 Age and intraoperative cardiopulmonary bypass time are the risk factors for autologous and allogeneic blood transfusion during heart valve replacement under direct vision, and the preoperative Hb content is a protective factor. It is necessary to evaluate the symptomatic treatment of patients before operation and reduce allogeneic blood transfusion.
