Objective To study the function of LSD1 in the development of neurons and the influence of LSD1 on mood and memory-related behavior in mice. Methods The LSD1(flox / flox) transgenic mice were crossed with Nestin?cre(Tg) transgenic mice, using Cre?LoxP recombination system, to generate LSD1 conditional knockout of neural stem cell ( LSD1?CKO) mice, LSD1(flox/ flox) Nestin?cre(Tg) mice, and LSD1(flox/ flox) mice as control. The neuron proliferation in LSD1?CKO mice was further detected by immunofluorescence staining. At the same time, the mood and memory?related behavior of LSD1?CKO mice were examined using several methods:sucrose preference test ( SPT) , forced swimming test ( FST) and novel?object recognition ( NOR) assay. Results In the LSD1 brain?specific CKO mice, the neuron proliferation rate in the hippocampus was significantly reduced ( P=0. 023 ) , the preference for sucrose was reduced ( P =0. 0075 ) , immobility duration during the forced swimming test was increased (P<0. 05), and LSD1?CKO mice also exhibits memory?decline (P=0. 0019) during the novel?object recognition test. Conclusions Depletion of LSD1 in mouse brain neural stem cells leads to significant reduction of the neuron proliferation in the hippocampus. LSD1?CKO mice show more negative emotions and memory impairment.

Objective To summarize the clinical nursing experience for patients with malignant obstructive jaundice after receiving percutaneous biliary radiofrequency ablation (RFA) and stent implantation. Methods The postoperative nursing experience in 9 patients with malignant obstructive jaundice who received percutaneous biliary RFA together with stent implantation were retrospectively analyzed. The postoperative complications and the nursing intervention measures were analyzed and evaluated. Results Biliary RFA and subsequent stent implantation were successfully carried out in all 9 patients. After the procedure, biliary fistula occurred in one patient, biliary hemorrhage in 2 patients and biliary infection in 2 patients. The patient, who developed biliary fistula, died one week later, and the clinical conditions in the remaining 4 patients were improved after symptomatic treatment. During the follow-up period of one month, the patients were in good condition. Conclusion The main purpose of postoperative nursing for patients after receiving percutaneous biliary RFA is to prevent the occurrence of bile duct perforation, hemorrhage, infection, etc. It is very important to keep the patients under close observation and comprehensive nursing so as to make an early detection and timely treatment of such complications, thus to reduce the incidence of complications causing serious consequences as well as to promote an early recovery.

BACKGROUND: It has been widely reported that the most types of cancer are probably originated from cancer stem cells (CSCs) which are subpopulations of tumor cells. Recent studies also suggested that lung cancer could arise from CSCs. However, the phenotypic characteristics of CSCs in lung cancer have not been precisely described.OBJECTIVE: To systematically analyze the expression of the most common CSC markers in cell line A549.METHODS: A549 cells were cultured for 1 week under the condition of conventional high glucose. After that, flow cytometry was used to assess the expression of putative stem cell markers, including CD133, CD24, CD44 and ABCG2.Cells were then sorted according to the expression of CD44 and CD24 markers by fluorescence-activated cell sorting (FACS) and characterized using their sphere-forming capacity in serum free medium supplemented with several growth factors.RESULTS AND CONCLUSION: A549 cells expressed the CSC markers CD44 and CD24 at 64.23％ and 58.62％,whereas the expression of both ABCG2 and CD133 was around 0.9％. Double-positive CD44/133 populations were rare.CD44+/CD24+ and CD44+/CD24- subpopulations respectively exhibited 54.64％ and 23.38％ expression. CD44+/CD24+ and CD44+/CD24- subsets were sorted by FACS. Both isolated subpopulations formed spheres in the serum free medium supplemented with basic fibroblast growth factor and epidermal growth factor. However, there was no significant difference in the sphere formation efficiency among CD44+/CD24+ and CD44+/CD24- subsets as well as A549 cells. Our findings suggest that CD44 and CD24 cannot be considered as potential markers for isolating lung CSCs in cell line A549, and further investigation using in vivo assays is required.

Objective To discuss the effective early postoperative fluid management in infant living-donor liver transplantation. Methods From January 2008 to March 2009, 17 cases of infant living-donor liver transplantation were carried out. According to infant postoperative physiological and hemodynamic characteristics, rehydration was properly controlled on the surgery day, the negative fluid balance was achieved as soon as possible in three days. The infant condition changes, vital signs and urine output were closely monitored. At the same time, the nature and volume of fluid infusion was timely adjusted to maintain the infant in a stable environment in accordance with the laboratory tests. Results The early postopera-donortive hemodynamic stability was effectively maintained in 17 cases of infants, no case appeared with the capacity-related complications. Conclusions It is the key to reduce postoperative complications and mortality with effective circulating blood volume and hemodynamic stability and the negative fluid balance state in the postop-erative 3 days.

Objective To investigate the myocardial protection of intraoperative continuous in-fusion of esmolol in elderly patients undergoing laparoscopic surgery.Methods Sixty patients,thirty-two males and twenty-eight females,aged 65-80 years,weighing 40-80 kg,ASA physical status Ⅰ orⅡ,undergoing selective general anesthesia laparoscopic resection of gastrointestinal cancer were ran-domly divided into 2 groups (n = 30 ):esmolol group (group E)and control group (group NS). Group E was administered esmolol 0.3 mg/kg 3 minutes before intubation,then with a continuously infusing rate of 50 μg · kg-1 · min-1 until extubation.Group NS was administered saline instead. MAP,HR,SpO 2 ,PET CO 2 ,BIS and RPP were recorded before intubation (T0 ),intubation (T1 ), pneumoperitoneum (T2 ),the end of surgery (T3 ),extubation (T4 )and 30 minutes after extubation (T5 ).The serum levels of cTnI,CK,CK-MB and LDH were measured before anesthesia and 6,30 hours after surgery.Adverse cardiovascular event happened during perioperation and 3 months follow-ing up was recorded.Results HR,MAP,RPP at T1 ,T2 ,T4 in group E were obviously lower com-pared with group NS (P <0.05).There were no significant differences in the serum levels of cTnI, CK,CK-MB and LDH between two groups at different time points.No major adverse cardiovascular event happened in two groups during perioperation and 3 months following up.Conclusion Intraoper-ative continuous infusion of esmolol 50 μg· kg-1 · min-1 can not significantly influence the serum level of myocardial injury marker in the elderly patients without myocardial damage undergoing lapa-roscopic resection of gastrointestinal cancer.Howerver,it can effectively reduce the cardiovascular re-sponse caused by stimulation,decrease myocardial oxygen consumption,protect myocardial.

Objective To investigate effect of hyperbaric oxygen therapy (HBOT) on delayed encephalopathy after carbon monoxide poisoning (DEACMP).Methods This was a prospective random study of 60 patients with DEACMP admitted to Beijing Tiantan Hospital.Among them,32 constituted the HBOT group and 28 were controls.All of the patients in both groups were given drugs to improve microcirculation and rehabilitation treatment.Additionally,the patients in the HBOT group were given hyperbaric oxygen therapy.The Mini-Mental State Examination (MMSE),the Barthel index and an index of age-related white matter changes (ARWMC) were used assess the patients' cognition,motor function and cerebral white matter lesions on the day of enrollment and on the 35th and 70th day after treatment.Results Before treatment there was no significant difference in average MMSE,Barthel index or ARWMC scores between the groups.In the HBOT group the average MMSE and Barthel index scores on the 35th and 70th day after enrollment were significantly higher than on the day of enrollment and the average ARWMC score on the 70th day was significantly lower than at enrollment.On the 35th day the average MMSE and Barthel index scores of the HBOT group were significantly higher than those of the control group,but there was no significant difference in the groups' average ARWMC scores.On the 70th day after enrollment the HBOT group's average MMSE and Barthel index scores were still significantly higher than those of the control group,but its average ARWMC score was significantly lower.Conclusion HBOT can help improve cognitive and notor function and also alleviate cerebral white matter lesions of DEACMP patients.
