Recent work has revealed that large numbers of mitotic figures are present in adult hearts,which has implied that there should be some mechanism about nature repair of the adult heart.But the levels of natural repair are not high enough to retrieval the traumatic myocardium.As a new approach to improving the cardiac repair,stem-cell therapy provides an exciting and powerful treatment.We describe the background of natural repair,and summarize the current strategies in the application of stem-cell therapy to repair the traumatic myocardium.

Objective:To discuss the experience accumulation and thinking tralning of clinical pharmacist in the pharmaceutical consultation with SOAP model. Methods:Clinical pharmacist performed the condition evaluation for one patient with Acinetobacter bau-rnannii infection after esophagus cancer surgery and was invited to the consultation for three times. Clinical pharmacist also provided the references for the drug treatment and monitored the whole process. Clinical pharmacist actively followed and pald return visits for the prognosis of the patient for one month. Results: After identifying the pathogen, the experiential therapy was given and the condi-tions of the patient were improved. According to the changes of the conditions, the treatment was adjusted in time with the most suitable drugs for the conditions and infection degree. Finally, the infection was controlled effectively, and the patient was discharged after the 35-day postoperative treatment. Conclusion:During the consultation, clinical pharmacist should correctly judge the conditions of pa-tients, summarize and evaluate the earlier therapy results, and then choose suitable drugs according to the property of PK/PD. Clinical pharmacist also should track the therapy results to assess the conditions of patients and individualize the treatment.

Objective To explore the emergent measures for hematomyelia during microendoscopic discectomy (MED). Methods Different measures, such as electrocoagulation, compression, irrigation, or hemostatic administration, were directed against different types of hematomyelia during MED. Results No conversions to open surgery for hematomyelia were required in all the 287 cases in the study. A follow-up for 4~30 months (mean, 17 months) was carried out. According to the MacNab criteria, excellent results were achieved in 219 cases, good results in 59 cases, fair in 7, and poor in 2. Conclusions Measures for hematomyelia during MED include the decrease of abdominal pressure, strict hemostatic performance, keeping off varicose veins when the protruded intervertebral disc is resected, compression by using gelfoam or styptic cotton, and intravenous administration of thrombin. These measures can effectively improve the surgical safety and the curative effect.

Objective To discuss surgical techniques during microendoscopic discectomy (MED) in the treatment of lumbar intervertebral disc herniation complicated with posterior longitudinal ligament calcification and osteophyte of posterior lumbar border. Methods The self-made arc-like annular knife and L-shape introducer were used during MED in the treatment of 115 patients. Results All the patients were followed for 12~30 months (mean, 22 months). According to the MacNab criteria, excellent or good results were achieved in 109 patients, fair results in 5 patients, and poor in 1, the rate of excellent or good results being 94.8% (109/115 ). No ruptured spinal dura mater, nerve root injuries, or infection of intervertebral space occurred. No conversions to open surgery were required. Conclusions Use of self-made instruments and corresponding modified techniques during MED can effectively manage the problems of posterior longitudinal ligament calcification and osteophyte of posterior lumbar border, which broadens the surgical indication and improves the efficacy and safety.

OBJECTIVE:To systematically review the efficacy of cetuximab combined with chemotherapeutics versus chemo-therapeutics alone in the treatment of metastatic colorectal cancer,and provide evidenced-based reference for clinical treatment. METHODS:Retrieved from Medline,PubMed,EMBase,CJFD,VIP,WanFang database and Cochrane Library,randomized con-trolled trials(RCT)about the efficacy of cetuximab combined with chemotherapeutics(test group)versus chemotherapeutics alone (control group) in the treatment of colorectal cancer were collected. Meta-analysis was performed by using Rev Man 5.2 software after data extract and quality assessment. RESULTS:A total of 12 RCTs were included,involving 8 514 patients. Results of Me-ta-analysis showed progression free survival in test group was significantly longer than control group,the difference was statistical-ly significant [HR=0.87,95%CI(0.79,0.95),P=0.002];compared with control group,there were no significant differences in the disease control rate[OR=1.06,95%CI(0.88,1.27),P=0.54] and overall survival[HR=0.92,95%CI(0.85,1.00),P=0.05] in test group. Results of subgroup analysis showed cetuximeb could significantly prolong the progression free survival of KRAS wild-type patients,the difference was statistically significant[HR=0.80,95%CI(0.66,0.98),P=0.03]. CONCLUSIONS:Compared with che-motherapeutics alone,chemotherapeutics combined with cetuximab can significantly prolong the progression free survival of pa-tients with metastatic colorectal cancer. Due to the limits of quality and sample size,more strict designed,long-term follow-up of large scale RCTs are needed for the further verification of the conclusion.

Objective To study the expression and clinical significance of survivin in acute leukemia. Methods By using semi-quantitative RT-PCR technique, survivin gene expression was detected in 43 acute leukemia(AL). Results Survivin gene expression rate in the cells of AL patients at diagnosis was 69.77%(30/43). Survivin mRNA expression rate in both 18 acute lymphocytic leukemia (ALL) and 25 acute nonlymphocytic leukemia(ANLL) (72.22% and 68.0% respectively) was signficantly higher than that in control group (33.33%,P0.05). Conclusions Survivin gene was highly expressed in AL patients and could be a potential target for treatment of AL.

Serial analysis of gene expression (SAGE) is a powerful high-throughput experimental technique that allows rapid, quantitative analysis of global gene expression in eukaryotic organisms. A short sequence taq (10~14 bp),which is defined by an anchoring enzyme site at a fixed distance from polyA tail, contains sufficient information to iden-tify mRNA transcript from which it originates. The taqs are ligated to obtain concatemers that are cloned into a plasmid vector for sequencing. The identification and abundance of mRNA can be observed through bioinformatics and statistical analysis of a given tag. SAGE is not only applied in obtaining global profile of gene expression in a given cell or tissue, but also help identify a set of specific genes to the cellular conditions by comparing the profiles constructed for a pair of cells that are kept at different conditions. This review covers a general introduction of SAGE, its protocol, meth-odological evolution and applications in parasite biology.

Aim To study the effect of Vitamin C on growth and apoptosis of human cervical cancer cell line HeLa and its mechanisms. Methods HeLa cell line was treated with VitC. Cell proliferation was evaluated with MTT assay. The distribution of cell cycle,the rate of apoptosis and the expression of HPV18 E6,p53,Bax and Bcl-2 protein of the heLa cells, were observed using flow cytometer respectively. TRAP-PCR-ELISA assay was used to evaluate telomerase activity. Results Vitamin C arrested the HeLa cell line in G_0/G_1 phase in a dose and time-dependent manner, and significantly inhibited HeLa cells growth and increased the rate of apoptosis.Expression of HPV18 E6 and Bcl-2 proteins, was down regulated expression of p53 and Bax proteins was upregulated, and the telomerase activity was reduced. Conclusion Vitamin C can significantly inhibit HeLa cells growth and proliferation,arrest them in G_0/G_1 phase and induce their apoptosis.The reason of these changes is the decrease of E6 gene′s expression, and the succedent changes of proteins′ expression in cancer cells,including the downregulated expression of HPV18 E6 and Bcl-2 proteins, upregulated expression of p53 and Bax proteins and reduced telomerae activity.

Objective: Giant left ventricle is one of the important dangerous factors impacting the results of valve replacement operation.In order to improve the efficiency of operation,we summarized our experience in valve replacement surgery for patients with giant left ventricle(LVEDD ≥ 7.0 cm).Methods: We retrospectively analyzed the clinical data of 138 cases of giant left ventricle treated by valve replacement operation in our hospital from June 1996 to April 2008.The preoperative left ventricular end diastolic dimension(LVEDD),left ventricle end systolic dimension(LVESD),left ventricular ejection fraction(LVEF) and left ventricular fractional shortening(LVFS) were 7.38-10.51 cm(mean 7.98?0.39),5.20-7.93(mean 5.88 ? 1.03),0.21-0.66(mean 0.43 ? 0.11) and 0.10-0.45(mean 0.25 ? 0.07),respectively.Eighty-nine of the patients had the heart function(NYHA) of class Ⅲ,and the other 49 class Ⅳ.Mitral valve replacement(MVR) was performed for 57 cases,aortic valve replacement(AVR) for 26,double valves replacement(DVR) for 40,and Bentall operation for the other 15.Meanwhile,78 of them underwent tricuspid valve plasty(TVP),and another 17(LVEDD ≥8.5 cm and LVEF ≤ 25%) partial left ventriculectomy(PLV).Results: The early postoperative mortality rate was 5.8%,mainly due to postoperative multiple organ failure,severe low cardiac output syndrome and ventricular fibrillation.Compared with the preoperative data,postoperative echocardiography showed that LVEDD and LVESD were decreased slowly at 2 weeks,and LVEF and LVFS significantly improved at 6 months.In the 17 patients who underwent PLV,LVEDD and LVESD were significantly reduced at 2 weeks,and LVEF and LVFS markedly improved.Conclusion:The key to the efficiency of valve replacement for giant left ventricle was proper choice of the blood containing stop-beating fluid during the operation,preserving the posterior valve of the mitral valve and the structure beneath it,shortening aortic cross-clamping time as much as possible,and perioperative prevention and management of arrhythmia.The short-term effect of valve replacement with simultaneous PLV is satisfactory,while its long-term effect is yet to be further investigated.
