Objective To compare the efficacy and safety of excimer laser 308 nm phototherapy alone and the combination of excimer laser 308 nm and topical application of vitamine D3 alanogue tacalcitol in the treatment of vitiligo. Methods Seventy-eight patients with vitiligo were enrolled in the single-blind clinical trial, treated with excimer laser 308 nm. The lesions were devided into two groups: patients in the experimental group were instructed to use tacalcitol ointment and the control group were applied with placebo ointment. The lesions were evaluated once per month and photos taken for analyses of clinical effects. Results The results in different locations were compared, the effective rates of the experimental group in cephalofacial site, trunk and limbs were 93.51%, 84.16 % and 42.35 %, respectively. The effective rates of control group in opposite and adjacent sites were 90.9 %, 77.45 % and 34.15 %, respectively (P < 0.05). The comparison of results in different types of lesions indicated that the effective rate of the experimental group in vitiligo vulgaris and segmental vitiligo were 73.81% and 84.00 %, respectively. The effective rate of control group in vulgaris and segmental vitiligo were 86.8 %, 77.45 % and 34.15 %, respectively (P <0.05 ). The comparison of results in radiation times and doses of phototherapy showed that the radiation time and dose on the time of initial pigment regeneration were (16. 15 ± 3.22)times and (4.40 ± 5.03)J/cm2 in the experimental group, while ( 18.56 ± 3.50) times and ( 6.60 ± 1.01 ) J/cm2 ( P < 0.05 ) in the control group, the time and dose on the time of apparent effect were ( 20. 36 ± 1.50 ) times and ( 7.50 ± 3.54 ) J/cm2 in the experimental group, and (21.68 ± 2.40) times and( 8.80 ± 9.24)J/cm2 (P < 0.05 ) in the control group. Conclusion Application of tacalcitol ointment in combination with twice-weekly 308 nm excimer laser light phototherapy is an effective alternative treatment for patients with generalized vitiligo.

OBJECTIVETo observe the efficacy on post-stroke mild cognitive impairment (MCI) treated with acupuncture at Jing-well points on the differentiated meridians and temple-three-needle therapy.
METHODSSeventy-three of stroke patients were randomized into an acupuncture group (37 cases) and a conventional treatment group (36 cases). Twenty healthy aged people in physical examination were collected as a control group. In the acupuncture group, on the basis of the conventional treatment of internal medication, the acupuncture at Jing-well points on the differentiated meridians and temple-three-needle therapy were applied. In the conventional treatment group, no any therapy was used except the conventional treatment of internal medication. In the control group, no any intervention was adopted. Neuroscan Nuamps electroencephalogram recording analysis system was used to determine the event-related potentials P300, and the amplitude and mini mental state examination (MMSE) score was observed before and after treatment in both groups.
RESULTSAfter treatment, in the acupuncture group, P300 latent stage was shortened, and the amplitude and the score of MMSE were increased (P < 0.05, P < 0.01). In the conventional treatment group, above indices were not changed obviously as compared with that before treatment (all P > 0.05). Compared with the conventional treatment group, the differences in P300 latent stage, amplitude and MMSE score were remarkable in the acupuncture group (P < 0.05, P < 0.01).
CONCLUSIONThe acupuncture at Jing-well points on the differentiated meridians and temple-three-needle therapy improves the cognitive function of the patients with MCI.

To explore the association between polymorphisms of transcription factor 7-like 2 gene (TCF7L2) and type 2 diabetes mellitus in Hefei district. The results suggest that the genetic variation DG10S478 in the TCF7L2 gene was not associated with type 2 diabetes mellitus in Hefei district ( P>0.05 ). However, its attribution to the susceptibility of type 2 diabetes mellitus in Hefei is not important.

OBJECTIVETo study the effect of ex vivo expansion on the adhesion activities of umbilical cord blood hematopoietic stem and progenitor cells (HSPC).
METHODSFresh UCB CD(34)(+) cells were cultured in a serum and stroma-free culture system. At day 7, day 10 and day 14, CD(34)(+) cells were re-selected from the expanded products. The expression of adhesion molecules (CAMs) such as VLA-4, VLA-5, LFA-1, ICAM-1, HCAM, L-selectin and PECAM-1, and the adhesion activity of the expanded CD(34)(+) cells were evaluated and compared with those of precultured fresh CD(34)(+) cells.
RESULTS(1) The CD(34)(+) cells expressing homing-related CAMs were increased (from 15-fold increase for CD(34)(+) CD(54)(+) subset to 72-fold increase for CD(34)(+) CD(49e)(+) subset at day 14). (2) The expressions of CD(49d), CD(44), CD(11a) and CD(49e) on the expanded CD(34)(+) cells were increased or sustained the same levels as those on fresh UCB CD(34)(+) cells, while the expression of CD(62L), CD(54) and CD(31) on expanded CD(34)(+) cells declined with the cultivating. (3) Spontaneous adhesion and SDF-1-induced adhesion tended to be increased in the course of the first 10 day's culture.
CONCLUSIONSThe culture system used in this study could substantially support the expansion of HSPCs expressing the above CAMs, and the expanded HSPCs would sustain their intrinsic adhesion potentials.

OBJECTIVETo study the effect of ex vivo expansion on the migration ability and the CXCR4 expression of umbilical cord blood (CB) hematopoietic stem/progenitor cells (HSPC).
METHODSCD(34)(+) cells isolated from fresh CB samples were cultured in a serum-free and stroma-free culture system. On day 7, 10 and 14, CD(34)(+) cells were re-selected from the expanded cells, and the expression of CXCR4 and the transmigration ability of these CD(34)(+) cells were evaluated respectively and compared with those of the precultured fresh CD(34)(+) cells.
RESULTS(1) SDF-1 induced a higher migration percentage of fresh or expanded CB CD(34)(+) cells than that of uninduced ones. (2) Both of the uninduced and SDF-1-induced migrations were slightly reduced in the first week and then much more reduced in the second week expansion (P < 0.05). (3) The number of the CD(34)(+)CXCR4(+) cells were significantly increased during the culture period, but there was a downtrend of CXCR4 expression on CD(34)(+) subset; the expression levels on day 10 and 14 were lower than that on day 0.
CONCLUSIONSThe expanded HSPC would sustain the chemotactic activity during one-week-culture, but with further extended culture time their intrinsic homing potential would be partly impaired.

Objective To compare the efficacy and safety of induction therapy in 3+7 protocol and 3+10 protocol in children with acute myeloid leukemia (AML). Methods Two protocols were carried out in our hospital during January 2010 to January 2015, namely 3+7 protocol(AML-06,A group) and 3+10 protocol (modified AML protocol, B group). A total of 56 cases aged from 1 year-old to 13 year-old were enrolled in A group with male to female ratio at 31:25. Five of them were classified as FAB M1, 25 as M2, 11 as M4, 10 as M5, 2 as M6 and 3 as M7. Another 44 cases aged from 1 year to 12 years were enrolled in B group with a male to female ratio at 26:18, and 17 cases were classified as FAB M2, 14 as M4, 9 as M5, 2 as M6, and 2 as M7. Efficacy and adverse events were compared between the two groups. Results The complete remission rate (CR) of B group was 70.4%, while CR in A group was 48.2%. Considering the CR, 3+10 protocol showed higher efficacy than 3+7 protocol (P< 0.05). The major adverse event was bone marrow suppression. Treatment-related mortality (TRD) in A group was 1.8%, which was lower than that in B group (2.3%). The overall survival rate in A group was 75.0%, which was lower than that in B group (86.4%, P< 0.05). Conclusions The induction therapy of 3+10 protocol and 3+7 protocol showed effectiveness for AML treatment. The 3+10 protocol showed a higher CR than 3+7 protocol with no TRD increase, indicating that the 3+10 protocol should be recommended for AML treatment in children.

BACKGROUND AND PURPOSE: Epidemiological data of cerebral small vessel disease (CSVD) in the general population of China are lacking. We report on the prevalence of lacunes, white matter hyperintensity (WMH), and cerebral microbleeds (CMBs) in a community-based sample in China and compare the results with those of other studies. METHODS: This was a cross-sectional analysis of the population-based Shunyi Study in China. A total of 1,211 stroke-free participants (mean age, 55.6±9.3 years; 37.4% men) with available 3 Tesla (3T) magnetic resonance images were included in this analysis. Demographic information and risk factor data were assessed. The overall and age-specific prevalence of lacunes, WMH, and CMBs was evaluated. Associations between cardiovascular risk factors and the presence of these lesions were analyzed by multiple logistic regression. RESULTS: Our study showed a prevalence of 14.5% for lacunes, 72.1% for periventricular hyperintensity (PVH), 65.4% for deep white matter hyperintensity (DWMH), and 10.6% for CMBs. When compared with other community-based samples, individuals in the same age group showed a higher burden of lacunes and a relatively lower prevalence of CMBs. Advanced age was independently associated with the prevalence of these CSVD markers, while the presence of hypertension increased the risk of lacunes, PVH/DWMH, and CMBs in deep or infratentorial locations. CONCLUSIONS: A higher burden of lacunes but a relatively lower prevalence of CMBs was observed in this Chinese population. This notable result highlights the challenge of CSVD prevention in China. Chinese have a risk factor profile for CSVD similar to those in other populations.
