Objective To assess the early prognosis of 117 patients after carduopulmonary resuscitation (CPR) in ICU by using the markers of inflammation,Glasgow Coma Scale (GCS) and Acute Physiology and Chronic Health Evaluation Ⅱ (APACHE Ⅱ) scores.Methods A total of 117 CPR patients admitted between 2010 January to 2012 December were enrolled for study.Within 24 h after admission,inflammatory markers,blood routine items,hepatorenal function,electrolytes of blood were measured.The GCS and APACHE Ⅱ scores were recorded.Arterial blood gas analyses were performed at 0,12,and 24 h after hospitalization,and the 12-h and 24-h lactate clearance rates were calculated.Seven days after treatment,according to the outcomes,the patients were divided into survival group and death group,and the clinical data of two groups were analyzed.Results (1) Of them,73 patients died and 44 survived.Factor analysis showed that age,time elapsed from resuscitation to ICU admission,D-dimer,arterial oxygenation index (FiO2),arterial blood pH,arterial blood lactate concentration upon ICU admission,GCS score and APACHE Ⅱ score were significantly different between the two groups (P ＜ 0.05or P ＜ 0.01); (2) Two classification logistic regression analysis showed that D-Dimer,GCS score and APACHE Ⅱ score significantly correlated with the mortality risk of the patients in the wake of CPR with relative odds ratios of 1.000,2.091,and 0.531,respectively (P ＜ 0.05 or P ＜ 0.01) ; (3) Receiver operating characteristic curve analysis indicated that the area under the curve of GCS (0.821) and APACHE Ⅱ (0.869) had higher predictive value than D-dimer (0.655).The highest accuracy (84.6％) in predicting patient survival was achieved when the GCS score was 6.5.Meanwhile,the highest accuracy (82.1％) in predicting patient death was achieved when the APACHE Ⅱ score was 17.5.Conclusions Both GCS score and APACHE Ⅱ score has obvious correlation with the prognosis of the critically ill patients after CPR and could be used to predict prognosis at early stage.

Background and purpose:miR-196a2 functions as an oncogene during tumor initiation and pro-gression. The up-regulation promotes tumor cell proliferation, invasion and metastasis. Therefore, it is promising to be an important tumor biomarker. The aim of this study was to investigate whether rs11614913, a gene polymorphic site ofmiR-196a2, is associated with the risk of leukemia.Methods:A case-control analysis was employed. Bone marrow or periph-eral blood was collected from 210 leukemia patients diagnosed from Jan. 2009 to Jul. 2015 in Yantaishan Hospital (case group) as well as 250 healthy people who were physically examined during the same period (control group). Polymerase chain reaction-restriction fragment length polymorphism (PCR-PFLP) was used to detect the genotype of rs11614913. Application test was used to compare the difference in the frequency of each genotype between case group and control group. The odds ratio (OR) of SNP allelic genes was calculated using logistic regression analysis and 95%CI represented the risk of leukemia for each genotype.Results:The distribution differences in the frequency of T/T, C/C, C/T genotype of miR-196a2 rs11614913 between case group and control group were statistically significant (P<0.05). The risk of leukemia for individuals who carried mutant homozygous C/C was 2.661-fold higher than those carried wild-type homozygous T/T, and the difference was statistically significant (P<0.05).Conclusion:ThemiR-196a2 gene polymorphic site rs11614913 was associated with the risk of leukemia. Mutant homozygous C/C or C allelic gene carrying was probably a risk factor for leukemia.

OBJECTIVETo study the effect of red peony root (RPR) on serum proteome in rat suffering from noxious heat with blood stasis Syndrome (NH-BS).

METHODSThe differences of serum proteome among rats in four groups, treated with lipopolysaccharide (LPS), RPR, LPS + RPR and saline respectively, were analyzed by bi-dimensional electrophoresis (2DE) assay. LPS was administered by intravenous injection and RPR by oral intake.

RESULTS(1) Serum of rats with LPS induced NH-BS showed significant changes in volume of serum protein (xPr) in 13 points on 2DE collagen, the volume of xPr 16 and 19 were significantly lower, volume of xPr 1, 2, 3, 4, 6, 7, 8, 9, 11, 12 and 23 were significantly higher respectively, as compared with those in the normal control group. (2) After being treated with RPR, the increased volume of xPr 1, 2, 3, 4 and 9 significantly decreased, and the decreased xPr 16 significantly increased, with xPr 2, 3 restored to normal level but the xPr16 still lower and xPr 1, 4, 9 higher than those in the normal group. RPR showed interaction with LPS on xPr 1, 3, 9, and 16. (3) For xPr 19, the interaction of RPR with LPS might be synergistic. (4) In the group treated with RPR, volumes of xPr 13 and 14 were significantly higher and those of 15, 17 were significantly lower than those in the normal group respectively, but the similar changes didn't found in the LPS group.

CONCLUSIONThe molecular basis of therapeutic effect of RPR on NH-BS might be through the regulation of xPr 1, 2, 3, 4, 9 and 16.

OBJECTIVE: To construct hypoxia/radiation inducible promotor HRE1.Egr-1, and to observe its promotive effect on the expression of yCDglyTK gene in nasopharyngeal cancer HNE-1 cells and the anti-tumor effect of yCDglyTK and to lay an experimental foundation for further exploration of new gene-radio therapy of nasopharyngeal cancer. METHODS: pcDNA3.1(-)HRE1.Egr-1.yCDglyTK was constructed by gene recombination technique. Stable yCDglyTK-expressing HNE-1 cells were generated by transfecting the recombinant plasmid into the target cells with liposome. The expression of yCDglyTK was detected by Western blot in 4 groups: a normoxia group, a radiation group, a hypoxia group, and a hypoxia and radiation group. The killing effect of 5-FC in different circumstances was determined by MTT. RESULTS: The expression of yCDglyTK/5-FC gene in all the groups was significantly different(P<0.01),especially in the hypoxia and radiation group. The killing effect of 5-FC on HNE1 cells varied under different conditions, especially in the hypoxia and radiation group. CONCLUSION Hypoxia and radiation can induce the activity of fusion promoter HRE1.Egr-1, and obviously promote the anti-tumor effect of yCDglyTK/5-FC system, suggesting that yCDglyTK may be a candidate suicide gene for gene-radio therapy of NPC.

OBJECTIVETo prepare anti-von Willebrand factor A3 (vWF-A3) domain monoclonal antibodies(mAbs) which block vWF-A3 binding to collagen, and characterize their biochemical properties and functions.

METHODSBALB/c mice were immunized with purified recombinant vWF-A3 protein (rvWF-A3). Murine anti-human vWF-A3 mAbs were developed by standard hybridoma technology and identified with ELISA. The recognition of the mAbs with rvWF -A3 and reduced human vWF was identified by Western-blot. The effect of mAbs on binding of purified human vWF to human placenta or calf skin collagen III was studied with collagen binding inhibition test.

RESULTSA group of 30 murine anti-human vWF-A3 mAbs was obtained, from which 2 clones were identified as inhibitory ones and designated as SZ-123 and SZ-125. SZ-123 and SZ-125 could react specifically with human vWF and rvWF-A3 respectively, while neither of them reacted with rvWF-A1 and rvWF-A2. Western-blot showed that SZ-123 and SZ-125 could recognize a 27 x 10(3) band of rvWF-A3 and 2 reduced human vWF bands at 250 x 10(3) and 170 x 10(3). SZ-123 and SZ-125 not only inhibited the binding of purified human vWF (1.5 and 3.0 microg/ml) to human type III collagen and to calf skin collagen III in a dose dependent manner, but also inhibited the binding of plasma vWF from human, rhesus monkeys or Beagle dogs to the two collagens.

CONCLUSIONSZ-123 and SZ-125 are neutralizing mAbs against vWF-A3 domain and may have therapeutic potential as an antithrombotic agent.

OBJECTIVETo discuss the early diagnostic methods and therapeutic principles of aneurysmal subarachnoid hemorrhage (SAH), and evaluate the therapeutic efficacy objectively.

METHODSUsing neuro-imaging examinations combined with case history and clinical symptoms to make the early diagnosis of 96 case with aneurysmal SAH, and Guglielmi detachable microcoil (GDC) was utilized for early intracapsular embolization in the ruptured aneurysms. Efficient symptomatic treatment was done early after operation.

RESULTSAll of 96 cases were early diagnosed and successfully embolized; Among them, the aneurysmal lumen was 100% occluded in 83 cases, 95% in 8 cases, 90% in 5 cases. There were 3 cases complicating with aneurysms rupture during operation, 5 cases with cerebral vasospasm. One case was affected by microcoil terminal escape after operation, 3 recurrent cases were all cured with secondary GDC embolization. There were 9 complications associated with embolization techniques and 13 cases (13.5%) occurring permanent sequelae associated with SAH. According to the Glasgow prognosis score, 77 patients got grade I, 7 grade II, 6 grade III, 3 grade IV, and 3 grade V. The mortality rate was 3.1%.

CONCLUSIONSTo make early etiological diagnosis of the SAH patients, using GDC to embolize the aneurysms, and earlier efficient symptomatic treatment are important methods to improve the curative rate and reduce the mortality rate.

OBJECTIVETo study the serum proteome of rat endotoxemia treated by figwort root (FR).

METHODThe differences of serum proteome among rats treated with lipopolysaccharide (LPS), FR, LPS + FR and saline respectively were analyzed by two-dimensional electrophoresis (2DE) assay.

RESULTThe volumes of sixteen serum proteins (xPr) in LPS induced-endotoxemia group were greatly changed compared with those of the control group. Among them, the volumes of xPr 16, 19 were significantly decreased, and the volumes of xPr 1, 2, 3, 4, 5, 6, 7, 8, 9, 11, 12, 14, 18, 23 were significantly increased. When treated with FR, the volumes of xPr 1, 6, 7, 8, 9, 11, 12, 14, 18, 23 were significantly decreased, and the volumes of xPr 8, 9, 11, 12, 23, 14 were back to normal level. Two factors statistic analysis showed that FR had interaction with LPS for xPr 1, 5, 8, 10, 11, 12, 18, 19, 20, 21, 22, and FR might be the functional antagonist of LPS. We also observed that the volumes of xPr 10, 13, 15, 20, 21, 22 were found to change significantly only in FR treated group but not in LPS treated group or control group. Interestingly, the volume of xPr 13, 20, 21, 22 were increased and the volume of xPr 10, 15 were decreased.

CONCLUSIONThe molecular basis of therapeutic effect of FR on endotoxemia might be through the regulation of xPr 1, 6, 7, 8, 9, 11, 12, 14, 18, 23. We can use proteomic techniques to study the molecular mechanisms of diseases treated by functional Chinese herbs and the combination of different herbs is necessary for the treatment of endotoxemia, as FR can not regulated all the changed proteins induced by LPS.
