ABSTRACT
OBJECTIVE@#To compare the clinical effect of wheat grain moxibustion combined with rehabilitation training and simple rehabilitation training on finger spasm after stroke.@*METHODS@#A total of 80 patients with finger spasm after stroke were randomly divided into an observation group and a control group, 40 cases in each group. The control group was given routine rehabilitation training, once a day, 30 min each time. The observation group was given wheat grain moxibustion at Shixuan (EX-UE 11) on the basis of the control group, 8~10 moxibustion cones at each point, once a day. Both groups were treated for 6 days as one course of treatment for 4 courses. The motor function of the affected hand (Fugl-Meyer assessment [FMA] score) and muscle tension (modified Ashworth scale [MAS] grading), surface EMG indexes (wrist dorsiflexor muscle and flexor carpal metacarpal muscle mean square [RMS] value), hand muscle strength (neurological deficit score [NDS]) and daily living ability (modified Barthel index [MBI] score) were compared between the two groups before and after treatment, and clinical efficacy was evaluated.@*RESULTS@#After treatment, FMA and MBI scores in the 2 groups were increased compared with before treatment (P<0.05), and those in the observation group were higher than the control group (P<0.05). The RMS value of wrist dorsiflexor muscle and flexor carpal metacarpal muscle in relaxation and passive function testsand and NDS in the 2 groups were lower than those before treatment (P<0.05), and those in the observation group were lower than the control group (P<0.05). MAS grading in the 2 groups was improved compared with before treatment (P<0.05), and that in the observation group was better than the control group (P<0.05). The total effective rate of the observation group was 92.5% (37/40), which was higher than that of the control group (80.0%, 32/40, P<0.05).@*CONCLUSION@#Wheat grain moxibustion at Shixuan (EX-UE 11) combined with rehabilitation training can improve the hand motor function and daily living ability of patients with finger spasm after stroke, improve the degree of spasm and the function of wrist dorsiflexor muscle and flexor carpal metacarpal muscle, the clinical effect is better than simple rehabilitation training.

<p><b>OBJECTIVE</b>To investigate the value of flow cytometry (FCM) detection in prognostic evaluation of minimal residual disease (MRD) of acute myeloid leukemia (AML) patients after allogeneic hematopoietic stem cell transplantation (allo-HSCT).</p><p><b>METHODS</b>Eighty-two cases of AML (except M3) after allo-HSCT who accord to enrolled condition (no MRD positive after allo-HSCT confirmed by regular flow cytometry detection and followed-up for 2 years) from April 2012 to September 2016 in our department were selected. Among 82 cases males were 50 and females were 32 with average age of 27.27 (2-57) years old. According to FAB classification, 2 cases were classified as M0/M1, 51 cases as M2, 24 cases as M4/M5 and 5 cases as M6. The antibody panels were selected accordingly to the initial leukemia associated immunophentype(LAIP) of patients.</p><p><b>RESULTS</b>Twenty patients (24.39%) were identified as MRD(0.10%-4.91%, mean 1.64%) in 82 AML patients after allo-HSCT (all the patients were in complete remission phase based on bone marrow morphology). During follow-up, 16 cases relapsed (relapse rate 80%)in 20 MRDcases, including 1 case with extramedullary relapse; 4 out of 62 MRDcases relapsed (relapse rate 6.45%)in bone marrow, and 2 cases extramedullary relapsed. The average survival time of leukemia- free survival (LFS) in group MRDwas 15.19 ± 3.99 months, median LFS was 10± 3.84 months. The average LFS time was 53.50 ± 1.69 months in MRDgroup (P<0.001). The average overall survival (OS) of the MRDgroup was 22.52 ± 5.72 months, the median OS was 18 ± 3.27 months; the average OS time was 42.86 ± 2.83 months in MRDgroup(P=0.008).</p><p><b>CONCLUSION</b>For the patients with morphologically complete remission after allo-SCT, the FCM regular monitoring of bone marrow MRD closely relates with its relapse rate, LFS and OS. Compared with the MRDgroup, the relapse rate of MRDgroup is significantly increases, and the LFS and OS significantly decreases.</p>
ABSTRACT
<p><b>OBJECTIVE</b>To study the effect and mechanism of mTOR signaling on adipogenesis of bone marrow mesenchymal stem cells(BM-MSCs) from aplastic anemia (AA) patients through regulation of PPARγ.</p><p><b>METHODS</b>BM-MSCs were isolated from 24 newly diagnosed AA patients and 24 healthy controls. The surface antigen expression of BM-MSCs was identified by flow cytometry. The capacity of adipogenic differentiation of BM-MSCs was determined by lipid droplets based on Oil Red O staining and by the expression of FABP4 based on Western blot. Protein levels of mTOR signaling and PPARγ were tested by immunofluorescence and Western blot.</p><p><b>RESULTS</b>AA BM-MSCs displayed an enhanced capacity of differentiating into adipocytes, compared with control BM-MSCs. It was found that mTOR was activated in AA BM-MSCs. Moreover, the expression levels of p-mTOR and PPAR-γ in AA BM-MSCs showed a parallel differentiation-dependent increase during adipogenic differentiation, which were significantly higher than that of control BM-MSCs at the same time point of adipogenic differentiation. mTOR inhibitor rapamycin did not only inhibit the adipogenic differentiation of BM-MSCs from AA pateints at the early-middle stage, but also partly reversed the adipogenic differention of BM-MSCs from AA pateints at the late stage by PPARγ regulation.</p><p><b>CONCLUSION</b>mTOR signaling may play a critical role in the adipogenic differentiation of BM-MSCs from AA patients by positively regulating PPARγ expression.</p>

A little is known about the specific marker on the surface of acute leukemia cells, leading to the lack of the specific diagnosis method for acute leukemia. Therefore, in this study, cell-systematic evolution of ligands by exponential enrichment (cSELEX) was performed to screen the aptamers binding to CD33(+)/CD34(+) cells from the patients with acute myeloblastic leukemia (AML) of M(2) subtype (AML-M₂) so as to provide the basis for finding the specific marker on the surface of AML-M(2) CD33(+)/CD34(+) cells. Firstly, AML-M₂ CD33(+)/CD34(+) cells were sorted and used as targeted cells, and normal CD33(+)/CD34(+)cells were used as counter-targeted cells; the aptamers binding to CD33(+)/CD34(+) cells from patients with AML-M₂ were screened from the single strand deoxyribonucleic acid (ssDNA) library by cSELEX. Subsequently, each aptamer structure was analyzed after cloning and sequencing. The results indicated that after 13 round of screenings, the enrichment of aptamers in the ssDNA library was ranged from 0.7% to 52.9%, and reached steady state at 13th round screening. Sequence analysis for 30 aptamers showed that most of the aptamers born one of the three conserved sequences of CCCCT, CTCTC, and CTCAC. Secondary structure analysis indicated that three different secondary structures existed in these aptamers. It is concluded that the aptamers binding to the AML-M(2) CD33(+)/CD34(+) cells are successfully screened, which lay the basis for further looking for the specific marker on the surface of AML-M₂ CD33(+)/CD34(+) cells, and the molecular diagnosis of the AML-M₂ leukemia.

<p><b>BACKGROUND</b>The 2009 influenza A (H1N1) virus infection is associated with the high risk of severe complications and is spreading more rapidly throughout the world than other reported seasonal influenzas. This study aimed to evaluate the efficacy and safety of the nature herbal medicine Lianhuaqingwen capsule (LHC) in patients infected with influenza A (H1N1) virus.</p><p><b>METHODS</b>A total of 244 patients aged 16 - 65 years confirmed with influenza A (H1N1) virus infection by the real time RT-PCR were randomized to one of two treatment groups of 122 patients each. Each group assigned to receive either LHC or Oseltamivir for five days and observation for seven days. The patients were enrolled within 36 hours of illness onset if they had an axillary temperature of ≥ 37.4°C and with at least one of the following symptoms: nasal obstruction, runny nose, cough, sore throat, fatigue, headache, myalgia, chills and sweating. The primary end point was the duration of illness.</p><p><b>RESULTS</b>Of 244 patients, 240 (98.36%) patients with a median age 21 years completed the study between October 24, 2009 and November 23, 2009. There were no significant overall differences between LHC treated and Oseltamivir treated patients in the median duration of illness (LHC 69 hours vs. Oseltamivir 85 hours P > 0.05) or the median duration of viral shedding (LHC 103 hours vs. Oseltamivir 96 hours, P > 0.05). However, it was worthwhile to note that LHC significantly reduced the severity of illness and the duration of symptoms including fever, cough, sore throat, and fatigue (P < 0.05). Both study medications were well tolerated. No drug related serious adverse events occurred during the study.</p><p><b>CONCLUSIONS</b>Compared with Oseltamivir, LHC achieved a similar therapeutic effectiveness reduction of the duration of illness and duration of viral shedding. Therefore, LHC might be an alternative therapeutic measure for influenza A (H1N1) virus infections.</p>
