BACKGROUND: Studies of umbilical cord blood stem cells transplantation for liver function failure have demonstrated that Astragalus membranaceus preparation can stimulate hemopoietic stem/progenitor cell proliferation.OBJECTIVE: To explore the effect of Astragalus membranaceus injection on the differentiation of umbilical cord blood stem cell into hepatocyte in vitro and in vivo for the treatment of liver failure. METHODS: The third and fourth passage of human umbilical cord blood stem cells (HUCBSCs) were collected. In drug screening test, there were 4 groups: cells were separately cultured with 0, 40, 200, and 400 mg/L Astragalus membranaceus injection to screen the appropriate for cell growth. In cell differentiation test, there were 2 groups: HUCBSCs were respectively cultured with hepatocyte growth factor (HGF, 10 μg/L), and HGF (10 μg/L) plus 200 mg/L Astragalus membranaceus injection. D-aminogalactose was intraperitoneally injected to establish a model of acute liver failure. Surviving model rats (48 hours) were randomly divided into six groups: model control, Astragalus membranaceus injection, rat peripheral blood mononuclear cells, combination, combination+Cytoxan, and combination+dexamethasone groups. The alpha fetoprotein mRNA and albumin mRNA expression was determined by RT-PCR, and liver function indexes were observed. RESULTS AND CONCLUSION: Different mass concentration of Astragalus membranaceus injection displayed varied influence on HUCBSC proliferation: 200 mg/L was the best for HUCBSC proliferation. Compared with HUCBSC cultured with HGF alone, the number of albumen-positive cells in HUCBSCs cultured with 200 mg/L Astragalus membranaceus injection and HGF was greater (P < 0.05). Moreover, the expression of albumen mRNA in combination, combination+Cytoxan, and combination+dexamethasone groups was greater than rat peripheral blood mononuclear cells group, while alpha fetoprotein mRNA expression was only greater than rat peripheral blood mononuclear cells group in early stage. At 7 days of treatment, the values of alanine aminotransferase, aspartate amino transferase and total bilirubin were significantly greater in combination, combination+Cytoxan, and combination+dexamethasone groups compared with model control, Astragalus membranaceus alone and rat peripheral blood mononuclear cells groups (P < 0.05), but no differences were observed among model control, Astragalus membranaceus alone and rat peripheral blood mononuclear cells groups (P > 0.05). Results indicate that Astragalus membranaceus injection at 200 mg/L can promote the proliferation and differentiation of HUCBSCs into hepatocyte in vitro and in vivo, ameliorate liver function and improve treatment effect of HUCBSC transplantation for liver failure.

Objective To investigate the effects of goal-oriented scheme for continuous mild sedation on patients with mechanical ventilation.Methods A total of 78 patients undergoing mechanical ventilation were enrolled via simple random number sampling method from January,2013 to December,2015,and divided into the experimental group(n=38)and the control group(n=40).The experimental group received goal-oriented scheme for continuous mild sedation designed by our department,and the control group received routine sedation protocol.Total sedative dosage,duration of mechanical ventilation,length of ICU stay,fatality rate in ICU,ventilator-associated pneumonia,pneumothorax,accidental extubation,tracheotomy were recorded.Results Duration of mechanical ventilation,length of ICU stay and total sedative dosage,incidence of ventilator-associated pneumonia and rate of tracheotomy in the experimental group were significantly lower than those in the control group and the differences were statistically significant(P＜0.05).There were no significant differences in accidental extubation,reintubation and barotrauma between two groups (P＞0.05).Conclusion Goal-oriented scheme for continuous mild sedation can reduce total sedative dosage,length of ICU stay,duration of mechanical ventilation,rates of ventilator-associated pneumonia and tracheotomy.It is safer and more effective which can improve the prognosis of mechanically ventilated patients.

Objective To compare the advanced non -small cell lung cancer (NSCLC)patients before and after chemotherapy peripheral blood EGFR mutation status,we understand whether the chemotherapy drug impacts the EGFR mutation status of the advanced NSCLC patients,so as to improve the precision of EGFR TKIs -drug use. Methods To collect the peripheral blood of 30 cases of advanced NSCLC before chemotherapy and after chemotherapy for 6 cycles.DHPLC technique was used to detect the EGFR mutation states of EGFR exon 19 and in exon 21.Results In 30 patients,chemotherapy prior EGFR mutation positive rate was 53.3% (16 /30).After 6 cycles of chemotherapy, the EGFR mutation positive rate was 36.6% (11 /30),the consistent rate was 56.6 (17 /30)before and after chemo-therapy,inconsistent rate was 53.4% (13 /30).10 cases from positive to negative before chemotherapy,3 cases from negative into positive before chemotherapy with statistical significance (P =0.046).Six EGFR19 exons changed, change rate of 20%,8 EGFR21 exons shift changed at a rate of 26%.EGFR19,21 shift in 1 case,with no statistical significance(P =0.39,P >0.05).Conclusion (1)The late NSCLC patients before and after peripheral blood of EGFR mutation status change,so before starting the targeted therapy we must recive real -time detection of peripheral blood EGFR mutation status,so as to decide whether to choose EGFR TKIs targeted drug therapy.(2)EGFR21 exons transformation rate is higher than EGFR19 exons conversion rate,but with no statistical difference,this phenomenon may be related to EGFR19 exons patients who with EGFR mutations -TKIs treatment efficiency is higher.
