Chronic myeloid leukemia (CML) is characterized by the accumulation of active BCR-ABL protein.Imatinib is the first-line treatment of CML;however,many patients are resistant to this drug.In this study,we aimed to compare the differences in expression patterns and functions of time-series genes in imatinib-resistant CML cells under different drug treatments.GSE24946 was downloaded from the GEO database,which included 17 samples of K562-r cells with (n=12) or without drug administration (n=5).Three drug treatment groups were considered for this study:arsenic trioxide (ATO),AMN107,and ATO+AMN107.Each group had one sample at each time point (3,12,24,and 48 h).Time-series genes with a ratio of standard deviation/average (coefficient of variation) >0.15 were screened,and their expression patterns were revealed based on Short Time-series Expression Miner (STEM).Then,the functional enrichment analysis of time-series genes in each group was performed using DAVID,and the genes enriched in the top ten functional categories were extracted to detect their expression patterns.Different time-series genes were identified in the three groups,and most of them were enriched in the ribosome and oxidative phosphorylation pathways.Time-series genes in the three treatment groups had different expression patterns and functions.Time-series genes in the ATO group (e.g.CCNA2 and DAB2)were significantly associated with cell adhesion,those in the AMN107 group were related to cellular carbohydrate metabolic process,while those in the ATO+AMN107 group (e.g.AP2M1) were significantly related to cell proliferation and antigen processing.In imatinib-resistant CML cells,ATO could influence genes related to cell adhesion,AMN107 might affect genes involved in cellular carbohydrate metabolism,and the combination therapy might regulate genes involved in cell proliferation.

AIM:To observe the changes of macular thickness in patients after cataract operation.
METHODS: A total of 126 patients ( 133 eyes ) were divided into two groups that were included in this study. The group (68 eyes of 64 case) with phacoemulsification combined intraocular lens implantation and ( 65 eyes of 62 cases ) with manual small incision cataract surgery ( MSICS) . There was no complication before and during the surgery. Optical coherence tomography ( OCT) was examined 1, 3mo before and after surgery. The visual acuity and macular thickness were compared after surgery. The SPSS 17. 0 software was used for statistical analysis. The paired t-test was used before and after surgery. Independent-samples t test was used in two groups before and after surgery,α=0. 05.
RESULTS: The cataract phacoemulsification group:preoperative and 1mo after surgery, the mean macular thickness was 241. 3±10. 9μm and 279. 7±16. 5μm, with significant difference ( P < 0. 01 ). The mean macular thickness was 245. 6±12. 6μm 3mo after surgery without statistical difference compared with preoperative ( P>0-05). The mean macular thickness was 279. 7±16. 5μm 1mo after surgery and 245. 6±12. 6μm 3mo after surgery with statistical difference(P<0. 05). Three eyes displayed cystoid macular edema at 1mo after surgery and 2 eyes of them was resolved 3mo after surgery. The group of MSICS: preoperative and 1mo after surgery, the mean macular thickness was 240-5±11. 9μm and 280. 7±16. 8μm, with significant difference (P<0. 01). The mean macular thickness was 246. 6±13. 2μm 3mo after surgery without statistical difference compared with preoperative ( P >0-05). One month after surgery and 3mo after surgery, the mean macular thickness were 280. 7±16. 8μm and 246-6±13. 2μm, with statistical difference (P<0. 05). Two eyes displayed cystoid macular edema at 1mo after surgery and 2 eyes were resolved 3mo after surgery. Between the two groups pre-operation or after operation for 1, 3mo respectively P values were without statistical difference (P>0. 05).
CONCLUSION: The macular thickness and macular edema can be found 1mo after cataract phacoemulsification and MSICS. Three months post-operatively, macular edema disappears and does not show statistical difference compared with preoperative. The increase of macular thickness has no obvious relationship with the choice of surgery.

Objective:To synthesize the mental resilience of Chinese children tested with the Resilience Scale for Chinese Adolescents (RSCA)to evaluate its status as well as the research status. Methods:Four Chinese elec-tronic databases including China Biology Medicine disc (CBM),VIP Database,China National Knowledge Infra-structure (CNKI)and WangFang Database were searched from database established to December 2014. Literatures that reported the mental resilience status of Chinese children tested with RSCA were included. A statistical formula was used to synthesize means and standard deviations to get a total score;the standard mean difference (SMD)and 95% confidence interval (95%CI)of scores measured with RSCA scale were used to conduct meta-analyses usingthe software of Review Manager 5. 2 for comparison between different subgroups. Results:Thirty-nine studies with 16 493 children were included for the final analysis. Quantitative synthesis results showed that the average total score of Chinese children was (3. 3 0. 6 ). The status of psychological resilience was at a good level. The average psychological resilience scores of girls,not left-behind children,urban children,Han children and not-only-child were higher than those of boys [SMD (95%CI):-0. 09 (-0. 14--0. 05 )],left-behind children [SMD (95%CI):-0. 37(-0. 56--0. 19)],rural children [SMD (95%CI):0. 26(0. 13 -0. 38)],minority children [SMD (95%CI):0. 12(0. 04-0. 21)]and only-children [SMD (95%CI):0. 30(0. 16-0. 44)]respectively. Conclusion:The mental resilience of Chinese children is modest with internal diversity.

OBJECTIVETo observe the clinical efficacy of acupuncture at Hegu (LI 4) on central facial nerve paralysis after ischemic stroke, and explore dose-effect relationship among different stimulation intensities of acupuncture at Hegu (LI 4) as well as its optimal treatment plan.
METHODSAccording to different acupuncture stimulation intensities which were based on treatment time and needle insertion direction, fifty patients were randomly divided into a Hegu 1 group, a Hegu 2 group, a Hegu 3 group, a Hegu 4 group and a control group, ten cases in each one. Different stimulation intensities of acupuncture at Hegu (LI 4) combined with facial paralysis acupoints, including Yingxiang (LI 20), Dicang (ST 4), Jiache (ST 6) and Quanliao (SI 18), were applied in Hegu 1 to 4 groups; meanwhile acupuncture at stroke acupoints, including Neiguan (PC 6), Shuigou (GV 26) and Sanyinjiao (SP 6), and medication treatment were adopted. Except acupuncture at Hegu (LI 4), the treatment of the control group was identical as Hegu groups. The treatment duration lasted for 14 days. The House-Brackmann facial never grading systems (H-B), Toronto facial grading system (TFGS), degrees of facial never paralysis (DFNP), facial disability index (FDI) and clinical efficacy were compared among groups.
RESULTS(1) Compared before the treatment, H-B, TFGS, DFNP and physical function score in FDI were all improved significantly in the Hegu 1 to 4 groups (all P < 0.05), but social function score in FDI was not obviously improved (all P > 0.05); all the scores in the control group were not evidently changed (all P > 0.05). (2) Compared with the control group, differences of H-B before and after treatment in the Hegu 1 to 4 groups, differences of TFGS in the Hegu 2 group and differences of DFNP in the Hegu 1 and Hegu 2 group were significantly improved (all P < 0.05). The differences of any scale among Hegu 1 to 4 groups were not significant (all P > 0.05), in which the most evident change was found in Hegu 2 group. (3) The total effective rate was 90.0% (9/10), 100.0% (10/10), 90.0% (9/10) and 80.0% (8/10) in Hegu 1 to 4 groups, which were significantly higher than 60.0% (6/10) in the control group (all P < 0.05).
CONCLUSIONAcupuncture at Hegu (LI 4) has affirmative clinical efficacy on central facial nerve paralysis after ischemic stroke, in which oblique insertion along the opposite direction of meridian for 5 s of twirling manipulation has the best clinical effect.

OBJECTIVETo observe the analgesic effects of single-and combined-laser irradiation with low-intensity applied at "Zusanli" (ST 36) in rats, and their relation to degranulation of mast cells.
METHODSSixty-six SD rats were randomly divided into 6 groups: normal control group (Group NC), model control group (Group MC), sham irradiation group (Group SI), 10.6 microm laser irradiation group (Group 10.6 microm LI), 650 nm laser irradiation group (Group 650 nm LI) and combined (10.6 microm + 650 nm) laser irradiation group (Group CLI). Complete Freund's Adjuvant (0.05 mL) was injected into the left ankle joints of all the rats except those in Group NC to cause acute adjuvant-induced arthritis. In treatment, laser irradiation was applied at "Zusanli" (ST 36) for 30 minutes in all the rats except those in Group NC and Group MC. The paw withdrawal latency (PWL) to radian heat was used to compare analgesic effects among the groups. By means of toluidine blue, dyed slices of local tissues of "Zusanli" (ST 36) were used to observe changes of mast cell degranulation before and after laser irradiation.
RESULTSThe pain thresholds to irradiation of the rats in Group 650 nm LI and Group CLI were significantly higher than those in Group MC and Group SI (P < 0.01), and the mast cell degranulation rate in Group 650 nm LI and Group CLI were also significantly higher than that in Group MC and Group SI (P < 0.001). The pain threshold and mast cell degranulation rate in Group 10. 6 microm LI were not significantly different from those in Group MC and Group SI. There was a linear correlation between mast cell degranulation rate and PWL with 0. 737 in coefficient (P < 0.001).
CONCLUSIONSingle 650 nm laser and combined 650 nm + 10.6 microm laser with low intensity irradiated at "Zusanli" (ST 36) in acute adjuvant rats can provide remarkable analgesic effects, and there was a positive correlation between mast cell degranulation rate and analgesic effects, which plays an important part in laser irradiation-induced analgesia.
