BACKGROUND:There is a group of leukemic stem cell (LSC) in patients with leukemia. These malignant stern cells, although rare, but self-renewal, with a certain degree of differentiation is the existence of leukemic cells and causes of their continued proliferation. Intervention of leukemia-specific targeted treatment drugs has become a research hotspot in recent years. OBJECTIVE: To investigate the influence of traditional medicine compound on expression of flt3 and N-ras mRNA in LSCs. DESIGN, TIME AND SETTING: A randomized, grouping experiment was performed at the Affiliated Hospital of Shandong University of Traditional Chinese Medicine from September 2007 to December 2008.PARTICIPANTS: A total of 50 cases of acute myelocytic leukemia admitted to Department of Hematology, Affiliated Hospital of Shandong University of Traditional Chinese Medicine and Qilu Hospital of Shandong University between 2006 and 2007 were selected, including 5 cases of type FAB, 15 of M2, 9 of M4 and 21 of M5.METHODS: Original prescription: Huangqi, Hedyotic diffusa, Xiaoji, Taizishen, Banzhilian, Pugongying, Rehmannia dride rhizome, Huangjing, Nuzhenzi, ecliptae herba, Tiandong, Maidong, Baizhu, Fuling, Liquorice root. Fuzheng prescription: Huangqi, Hedyotic diffusa, Xiaoji, Banzhilian, Pugongying, ecliptae herba. Preparation: the above-mentioned three groups of drugs were prepared into 1 g/mL medicine liquid by Laboratory of Chinese Drug Preparation of Affiliated Hospital of Shandong University of Traditional Chinese Medicine. When it was negative in sterility test, the liquid was filtrated and sterilized. 5 mL bone marrow was separately harvested from M1, M2, M4, and M5 leukemia patients, diluted and placed in lymphocyte isolation solution. LSCs were purified by magnetic activated cell sorting and flow cytometry. The cell concentration was adjusted to 2×108/L and divided into 4 groups: control (no treatment), and three experimental groups (treated separately with original, Fuzheng, Quxie prescriptions at final concentration of 100 mg/L). The cells were cultured for 48 additional hours. MAIN OUTCOME MEASURES: RT-PCR was used to detect the mRNA expressions of Flt3 and N-ras in LSCs. RESULTS: The expression of flt3 in three experimental groups was significantly decreased compared with control group (P < 0.05), in particular, original prescription group decreased the most (P<0.05), and no significant difference was found between Fuzheng and the Quxie prescription groups (P>0.05). The expression of N-ras in four groups was similar to Flt3. CONCLUSION: Flt3 and N-ras mRNA were overexpressed in LSCs. Chinese medicine original prescription and its Fuzheng or Quxie prescriptions decreased Flt3 and N-ras mRNA expression.

Objective:To explore the clinical characteristics and prognostic risk factors of accidental injuries in pediatric intensive care unit(PICU).Methods:The children with accidental injuries admitted to the PICU at Shanghai Children′s Hospital from January 2017 to December 2019 were analyzed retrospectively.The patients were divided into survival group and death group according to outcome.We collected the patients′ clinical data and laboratory indexes, and analyzed the differences between two groups.Multivariate Logistic regression was used to screen the risk factors of death and receiver-operating characteristic(ROC)curve was used to determine the threshold.Results:(1)A total of 253 children were included, accounting for 5.2% of PICU hospitalization during the same period.There were 137 males(54.2%)and 116 females(45.8%), with an average age of 45(19, 96)months.The top three causes of accidental injuries were fall injury in 82 cases(32.4%), traffic accident in 70 cases(27.7%)and foreign body in 39 cases(15.4%). There were 22 cases of deaths, with a fatality rate of 8.7%.(2)The mean arterial pressure at admission in the death group was lower than that in the survival group( P<0.05), and the total length of stay was longer( P<0.001). There were significant differences in Glasgow coma scale, Pediatric Risk of Mortality Scoring Ⅲ(PRISM Ⅲ)between the two groups( P<0.001). In the death group, and the blood lactic acid(LA) significantly increased( P<0.001), hemoglobin and fibrinogen were lower than those in the survival group, the activated partial thromboplastin time and prothrombin time(PT)were significantly prolonged( P<0.001). (3)Multivariate Logistic regression analysis showed that PRISM Ⅲ score, LA and PT were independent risk factors for the death of accidental injuries.The area under curve(AUC)of PRISM Ⅲ score was 0.987(95% CI 0.976-0.999, P<0.001)and the cut-off value was 11 with a sensitivity of 100% and a specificity of 95.7%.The AUC of LA was 0.886(95% CI 0.810-0.961, P<0.001)and the cut-off value was 3.1 mmol/L with a sensitivity of 85.7% and a specificity of 77.3%.The AUC of PT was 0.835(95% CI 0.730-0.941, P<0.001)and the cut-off value was 13.9 s with a sensitivity of 86.6% and a specificity of 72.7%. Conclusion:The main accidental injuries in PICU of our hospital in the past three years are falling injuries, traffic accidents and foreign body injuries.PRISM Ⅲ score, LA and PT at admission are independent risk factors for predicting death.
