Objective:To observe the clinical efficacy of treating infantile diarrhea due to spleen deficiency with five-step pediatric tuina of Huxiang school. Methods:Using a randomized controlled trial design, sixty eligible kids with diarrhea due to spleen deficiency were randomized into an observation group and a control group, with 30 cases in each group. The observation group was intervened by the five-step pediatric tuina method of Huxiang school, and the control group received conventional tuina treatment. The intervention was conducted once a day, consecutive 5-day treatment as 1 course, at a 2-day interval between courses, successively for a total of 4 courses. Changes in the primary and secondary symptoms of diarrhea due to spleen deficiency were observed, and the clinical efficacy was evaluated. Results: After treatment, the scores of primary and secondary symptoms and the general score of diarrhea due to spleen deficiency were improved; the improvements in fecal form and frequency, decreased appetite, bloating after meals and fatigue and sluggishness were more significant in the observation group than in the control group. Conclusion: The five-step pediatric tuina method of Huxiang school and conventional tuina both can improve the primary and secondary symptoms in infantile diarrhea due to spleen deficiency, while the former one can produce more significant efficacy.

OBJECTIVETo investigate the distribution of constitution types of Chinese medicine (CM) in the elderly living at home in Beijing downtown, and to explore its relationship with life habits.

METHODSA total of 3894 senile more than 60 years old were enrolled in this study. Their constitution types of CM were typed using CM constitution questionnaire. Meanwhile, their demographic features, disease condition, diet habits, exercise habits, sleep habits, and so on were investigated. Multivariate Logistic regression analysis was used to evaluate the relationship between life habits and constitution types of CM.

RESULTSThe number of mild type constitution senile was 1111 (28.53%) and the number of biased constitutions 2783 (71.47%). Biased constitutions of the top three were qi deficiency constitution (662, 17.00%), yang deficiency constitution (445, 11.43%), and blood stasis constitution (363, 9.32%). Univariate analysis showed that different habits of diet, exercise, and sleep exist among the senile of different constitutions (P < 0.05). By taking mild type constitution, multivariate Logistic regression analysis (except demographic indices and chronic history) showed that significantly positive correlation existed between qi deficiency constitution and favor for hot food (OR = 1.349, P = 0.015), yang deficiency constitution and favor for hot food (OR = 2.448, P < 0.01), phlegm-wetness constitution and favor for barbecue food (OR = 2.144, P = 0.003), wet-heat constitution and favor for sweet food (OR = 1.355, P = 0.032), wet-heat constitution and favor for tea (OR = 1.359, P = 0.047), blood stasis constitution and favor for hot food (OR = 1.422, P = 0.017), and qi depression constitution and favor for hot food (OR = 1.446, P = 0.031). Regular exercise had negative correlation with qi deficiency constitution (OR = 0.397, P < 0.01), yang deficiency constitution (OR = 0.522, P < 0.01) , phlegm-wetness constitution (OR = 0.475, P < 0.01), wet-heat constitution (OR = 0.647, P = 0.015), blood stasis constitution (OR = 0.608, P = 0.001), qi depression constitution (OR = 0.541, P = 0.001), and special diathesis constitution (OR = 0.466, P < 0.01). Early sleep and rise habit had negative with phlegm-wetness constitution (OR = 0.414, P < 0.01), wet-heat constitution (OR = 0.536, P = 0.015), blood stasis constitution (OR = 0.515, P = 0.004), and special diathesis constitution (OR = 0.526, P = 0.039).

CONCLUSIONSDifferent constitution types of CM might be highly related to specific life habits. Cultivating better life habits can improve biased constitutions of CM.

Objective: To explore the protective mechanism of acupuncture plus mild hypothermia for cerebral ischemia-reperfusion injury (CIRI) by observing the effects of acupuncture plus mild hypothermia on miRNA-204 and its target gene expressions in CIRI rat brain tissues. Methods: Sixty Sprague-Dawley rats were divided into a blank control group, a sham operation group, a model group, an acupuncture group, a mild hypothermia group and an acupuncture plus mild hypothermia group according to the random number table method (n=10). Except for the blank control group and the sham operation group, rats in the other 4 groups received CIRI modeling. After the model was successfully established, rats in the blank control group were bred routinely for 72 h without any interventions; rats in the sham operation group and the model group were bred routinely for 72 h, and only received binding without other interventions after surgery; rats in the acupuncture group were bred routinely for 72 h, and received acupuncture at Dazhui (GV 14), Baihui (GV 20) and Shuigou (GV 26) after binding; rats in the mild hypothermia group were bred routinely for 72 h, and received mild hypothermia intervention for 72 h after binding; rats in the acupuncture plus mild hypothermia group were bred routinely for 72 h, followed by receiving acupuncture as in the acupuncture group and mild hypothermia therapy as in the mild hypothermia group after binding. The neurological impairment score, cerebral infarction area ratio, the expressions of miRNA-204 and its target genes including Map3k8, Ntrk2 and Ppp3r1 in the ischemic hippocampus of each group were observed after 72 h of intervention. Results: Before intervention, compared with the blank control group and the sham operation group, the neurological impairment scores and the infarction area ratios of the modelled rats were statistically significantly increased (all P<0.01), indicating that the model was successful. After intervention, compared with the model group, the neurological impairment scores of the three intervention groups were significantly reduced (all P<0.01); compared with the acupuncture group and the mild hypothermia group, the infarction area ratio in the acupuncture plus mild hypothermia group was significantly reduced (both P<0.01); compared with the model group, the three intervention groups showed significant inhibition of miRNA-204 expression in brain tissues (all P<0.05), which was most significant in the acupuncture plus mild hypothermia group (P<0.01); compared with the acupuncture group and the mild hypothermia group, the Map3k8 expression in the acupuncture plus mild hypothermia group was significantly increased (both P<0.01), but there were no significant differences in Ntrk2 and Ppp3r1 expressions between groups (all P>0.05). Conclusion: Acupuncture, mild hypothermia, and acupuncture plus mild hypothermia reduced the neurological impairment score and the cerebral infarction area in CIRI rats, while acupuncture plus mild hypothermia showed the most significant effect. In regulating miRNA-204 target gene expressions, acupuncture plus mild hypothermia showed the same effect on Ntrk2 and Ppp3r1 expressions, while better effect on Map3k8 expression compared with either acupuncture or hypothermia.

The objective was to study the incidence and prognosis significance of -7/7q- abnormalities in acute leukemia and myelodysplastic syndrome. Conventional cytogenetic analysis of R-band was used to test -7/7q- chromosome abnormalities in 410 patients with acute leukemia (AL), in 71 cases of myelodysplastic syndrome (MDS) and in 36 cases of chronic myelogenous leukemia in accelerated phase (CML-AP). The results showed that the incidences of -7/7q- abnormalities in AL, MDS and CML-AP patients were 4.88%, 9.86% and 8.33% respectively. The -7/7q- abnormalities could be found in acute myeloblastic leukemia (AML) and acute lymphocytic leukemia (ALL), incidences of which were 4.70% and 6.25% (P > 0.05) respectively. 9 cases had -7 or 7q- as the sole chromosome abnormalities, 22 cases showed other additional chromosome abnormalities: -X, -5, +8, t(3; 3), t(11;16) and t(2;11). Monosomy -7 and 7q- abnormality clone was found in one patient with MDS-RAEB, and the number of cells with -7 abnormality was greater than that of 7q- abnormality cells. Four patients acquired CR among 7 patients with ALL after chemotherapy, but 2 out of 13 patients with AML achieved CR while 6 out of 7 patients with MDS transformed into AL. No patients with CML-AP achieved CR. In conclusion, -7/7q- is a frequent aberration in hematologic malignancies as well as AML and ALL. The monosomy -7 and 7q-abnormalities were detected in the same patient. The patients with -7/7q- abnormalities show poor prognosis.

A CALLG2008 protocol was developed by the Chinese Acute Lymphoblastic Leukemia Cooperative Group for adult acute lymphoblastic leukemia (ALL).We retrospectively analyzed 153 newly diagnosed adult patients with Philadelphia chromosome (Ph)-positive ALL enrolled into imatinib (400 mg/d) plus CALLG2008 regimen between 2009 and 2015.The median age was 40 years (range,18-68 years),with 81 (52.3％) males.The overall hematologic complete remission (CR) rate was 96.7％ after induction.With a median follow-up of 24.2 months,the estimated 3-year overall survival (OS) and event-free survival (EFS) rates were 49.5％ (95％ confidence interval (CI):38.5％-59.5％) and 49.2％ (95％ CI:38.3％-59.2％),respectively.Fifty-eight (36 with haploidentical donor) patients underwent allogeneic hematopoietic stem cell transplantation (allo-HSCT) in first CR.Among the patients in CR1 after induction,both the 3-year OS and EFS were significantly better in the allo-HSCT group than in the without allo-HSCT group (73.2％,95％ CI:58.3％-83.5％ vs.22.2％,95％ CI:8.7％-39.6％ and 66.5％,95％ CI:50.7％-78.2％ vs.16.1％,95％ CI:5.1％-32.7％,respectively).Multivariate analysis showed that allo-HSCT and achievement of major molecular response were associated with favorable OS or EFS independently.Interestingly,in the allo-HSCT cohort,the donor type (haploidentical versus matched donors) had no significant impact on EFS or OS.All these results suggested that imatinib plus CALLG2008 was an effective protocol for Ph-positive ALL.Haploidentical donors can also be a reasonable alternative expedient donor pool.

OBJECTIVETo evaluate the expression of CD133 and its clinical significance in acute leukemia (AL) patients.

METHODSThe expression of CD133 and CD133 mRNA in leukemic blasts from 76 AL patients were detected by three-color flow-cytometry and hemi-quantitative RT-PCR respectively.

RESULTS(1) CD133 mRNA expression was highly correlated with CD133 expression in both of normal donors and AL patients groups. The expression of CD133 in AL patients was significantly higher than that in control group (P < 0.01). (2) The positive rates of CD133 and CD133 mRNA in AL group were 42.1% (32/76) and 46.1% (35/76) respectively. There was no significant difference in CD133 expression between AML-M(3) and normal control, AML and ALL, as well as T-ALL and B-ALL. The expression of CD133 in AML-M(4) were significantly higher than those in other AML subtypes (81.8% vs 43.7% and 81.8% vs 46.9% at CD133 and CD133 mRNA level, respectively, P < 0.01). (3) The expression of CD133 in AML was significantly correlated with the expression of CD34 and HLA-DR (P < 0.001). (4) The expression of CD133 had no relationship with the clinical prognostic factors such as cytogenetic or molecular aberrations, WBC counts, LDH, mdr1 expression and age. (5) There was a trend toward lower CR rate in CD133(+) cases, but only CD34/CD133(+) double positive cases had significant lower CR rate than that of negative ones (44.4% vs 71.4%, P < 0.05).

CONCLUSIONSAL had significantly higher CD133 expression compared to normal control. The detection of CD133 expression might help to identify AL type and predict therapeutic outcomes. Co-expression of CD133/CD34 might convey adverse prognosis of AL.

OBJECTIVETo inhibit the expression of beta-catenin and investigate the effect of the beta-catenin gene on Jurkat and K562 cells.

METHODSsiRNA specifically knocking down the expression of beta-catenin was used to testify the function of beta-catenin in Jurkat and K562 cells. Real time polymerase chain reaction and Western blot were performed respectively to testify the mRNA level and protein level of beta-catenin. Growth curve was determined by counting viable cells using trypan blue refusal-dyed method. The proliferation of cells was assayed by clonogenic counting and MTT method. The apoptotic cells were measured by Annexin V/PI staining. The cell cycle analysis was performed based on propidium iodide staining.

RESULTSCompared with the control group (transfected with siRNA directed against scramble gene), the survival, colonogenicity, and proliferation of the Jurkat and K562 cells were significantly decreased in experimental group transfected with beta-catenin siRNA. The colonogenicity was decreased from 31.9 +/- 5.55 (siRNA) to 25.0 +/- 5.13 (control) in Jurkat cells, and from 47.33 +/- 8.52 (siRNA) to 39.33 +/- 6.26 (control) in K562 cells (both P <0.05). The inhibition rate was (49.3 +/- 9.86)% (siRNA) and (15.1 +/- 6.55)% (control) respectively in Jurkat cells, and (39.4 +/- 7.56)% (siRNA) and (10.1 +/- 6.89)% (control) in K562 cells (both P <0.05). In addition, the apoptotic rate increased from (23.5 +/- 2.82)% (control group) to (55.9 +/- 2.22)% (experiment group) in Jurkat cells and from (14.9 +/- 8.54)% (control group) to (27.9 +/- 15.3)% (experiment group) in K562 cells. However, cell cycle analysis revealed no obvious phases change both in Jurkat and in K562 cells.

CONCLUSIONKnock-down of beta-catenin gene may decrease the proliferation, survival, and clonogenicity in Jurkat cells and K562 cells.

OBJECTIVETo investigate the expression of beta-catenin in patients with leukemia and explore its significance in leukemias.

METHODSRT-PCR was used to detect the expression of beta-catenin in bone marrow mononuclear cells (BMMNCs) from patients with leukemia. Immunocytochemistry was in some of patients to detect the distribution of beta-catenin at the same time. The clinical significance of beta-catenin was analyzed in combination with patients' clinical information.

RESULTSExpression of beta-catenin was statistically higher in acute myeloid leukemia (AML) and acute lymphocytic leukemia (ALL) samples than in normal donors (P = 0.001 and 0.016 respectively) and chronic phase chronic myeloid leukemia (CML) patients (P = 0.001 and P = 0.008 respectively), while there was no statistic difference between AML and ALL patients (P = 0.58). In addition, beta-catenin expression in chronic phase CML patients was like that in normal donors (P = 0.49), but increased significantly in blast crisis and accelerated phase. Immunocytochemical analysis revealed that BMMNCs from normal donors expressed beta-catenin on the plasma membrane and cytoplasma, while those from acute leukemia expressed beta-catenin to varying degrees in the nucleus as well. The expression of beta-catenin gene statistically showed the highest level in M5 (n = 15) and the lowest level in M3 (n = 18). No clinical features, such as, age, initial WBC count, therapy response rate, blast cell numbers or cytogenetic risk was found to be correlated with the expression of beta-catenin excepting for CD34+ positive rate (P = 0.004) in AML.

CONCLUSIONAs a key mediator of Wnt signal transduction way, overexpression of beta-catenin in leukemia cells indicates that it might be aberrantly activated in acute leukemia, accelerated or blastic phase of CML.

OBJECTIVETo evaluate the efficacy and safety of the HAA regimen (homoharringtonine,cytarabine and aclarubicin)as salvage chemotherapy in the treatment of refractory/relapsed acute myeloid leukemia (AML).

METHODSWe retrospectively analyzed 64 patients with refractory/relapsed AML who received the HAA regimen as salvage chemotherapy. The complete remission (CR)rate was analyzed. Kaplan-Meier method was used to estimate overall survival (OS) and relapse free survival (RFS), and the differences were compared by Log-rank test.

RESULTSThe overall CR rate was 70.1%, and 67.1% of the patients attained CR after the first induction course. The early death rate was 0. The median follow-up time was 61 (range:6-120) months. The estimated 3-year OS rate was 46.8% and the estimated 3-year RFS rate was 42.8%. The CR rates of patients with favorable/intermediate and unfavorable cytogenetics were 76.4% and 33.3%, respectively. The 3-year OS of favorable/intermediate and unfavorable group were 53.7% and 10.0%, respectively. The median survival time of unfavorable group was only 8 months. The side effects associated with the HAA regimen were tolerable, in which the most common toxicities were myelosuppression and infection.

CONCLUSIONHAA regimen is associated with a higher rate of CR and longer-term survival and its toxicity can be tolerated. The regimen is suitable for refractory/relapsed AML patients with favorable or intermediate risk .
