Objective To study the influence of survivin mutant-T34A ( survivinT34A) and survivin deletant-N-terminal 8 amino acids residues ( survivinN-8AA ) on the cell cycle distribution and chemosensitivity in human ovarian cancer HO-8910 cells for explorating the roles of modified survivin-mediated apoptosis induced by chemotherapeutic agents and possible signaling pathways involved. Methods pcDNA3.1 plasmid contained wild-type, survivinT34A and survivinN-8AA genes were transfected into HO-8910 cells,respectively, the control groups were HO-8910 cells transfected with pcDNA3. 1 plasmids. The expression of mRNA was examined by reverse transcription(RT) PCR and identified by DNA sequencing; the cell cycles were determined by flow cytometer analysis ( FCM ); the growth inhibitions rate of cisplatin ( DDP),paclitaxel (PTX) and LY294002 on the transfected cells were determined using methyl thiazolyl tetrazolium (MTT) assay. Results (1) The RT-PCR procedures and genome sequences showed that the survivin mRNA were expressed stable in the transfected HO-8910 cells. (2) There was lower percent of G0/G1 phase cells in SN-HO-8910 cells than that in PC-HO-8910 cells (44. 72% vs. 49.64%, P <0. 05) ;while higher percentage of G2/M phase and S phase cells( 1.06% and 54. 22% vs. 0. 56% and 49. 80%, P < 0. 05 ).There was lower the G2/M phase and S phase cells in M-HO-8910 cells 0. 16% and 36. 33%, than that in PC-HO-8910 cells( P < 0. 05 ); while higher percentage of G0/G1 phase cells(63. 51% ,P < 0. 05 ). G0/G1 ,G2/M and S phase cells in Sur-HO-8910 cells were 54. 46%, 0. 62% and 44. 92%, and there were not significantly difference ( P > 0. 05 ), compared to those in PC-HO-8910 cells. ( 3 ) The inhibitory concentration ( IC50 ) of DDP and PTX were higher in Sur-HO-8910 cells than those in control cells [(20. 4 ±6. 1)vs. (14.4 ±3.9)μmol/L,(36.7 ±4.0) vs. (28.6 ±3.6) μmol/L;all P<0.05]. The IC50 of DDP and LY294002 in SN-HO-8910 cells were lower than those in control cells[(7. 6 ± 1.0) vs. ( 14. 4 ± 3.9)μmol/L, ( 13.2 ± 4. 0) vs. (41.0 ± 7. 9 ) μmol/L; all P < 0. 01]. The IC50 of PTX [( 37. 9 ± 4. 8 ) μmol/L]in SN-HO-8910 cells were higher than that in control cells(P <0. 05). The IC50 of DDP in M-HO-8910 cells [(9.9 ± 1.2) μmol/L] were lower than that in control cells(P <0. 05) ,and the IC50 of LY294002 in M-HO-8910 cells [(66. 9 ± 4. 8) μ mol/L] higher than that in control cells ( P < 0. 01 ). Conclusions The changes of cells cycle distribution caused by survivinT34A or survivinN-8AA enhanced the G2/M cell cycle-dependent chemosensitivity of PTX. Compared to survivinT34A, survivinN-8AA preferentially to mediate the cytotoxicity of DDP and LY294002, suggesting that it may be related to the cell cycle-dependence of survivin function and to blockage of the formation of its active dimer.

Objective:
On the basis of the dominant frequency index of functional connectivity, the "brain age" analysis method was used to explore abnormal development patterns of sensorimotor networks in boys with autism spectrum disorder(ASD).
Methods:
The resting state functional magnetic resonance data (7-12 years old) for 105 boys with ASD and 102 matched boys with normal development from the ABIDE public database were screened. Functional connection networks in different frequency bands of sensorimotor related brain regions were constructed for each individual, and the frequency of the strongest connection were constructed as the optimal frequency of the connection. Brain age analysis was used to explore the difference between brain age and chronological age in boys with ASD.
Results:
The brain sensorimotor network of boys with ASD showed an abnormal development pattern of overdevelopment followed by underdevelopment, and the transition between the two patterns occurred at approximately 7.8 years of age. Older boys with ASD (older than 10 years) whose underdevelopment trend was suppressed had lower ASD severity( r=-0.43, P < 0.05 ).
Conclusion
The brain sensorimotor network in boys with ASD has an abnormal development process, and the brain chronological age difference in the sensorimotor network has potential as a neuroimaging marker to measure the development of ASD.

OBJECTIVETo investigate the value of serum IgA/C3 ratio in the diagnosis of IgA nephropathy and explore its relationship with the clinicopathological features of the patients.
METHODSSixty-six patients with IgA nephropathy, 111 with other glomerular diseases, and 40 healthy control subjects without kidney disease were tested for serum IgA and C3 levels using CRM470 adjusted standardized immune turbidimetric method, and the IgA/C3 ratio was calculated. According to Oxford and Lee's classification criteria, we analyzed the pathological grades of the renal biopsy samples from patients with IgA nephropathy. The ROC curve was used to assess the value of serum IgA and IgA/C3 ratio in predicting IgA nephropathy.
RESULTSPatients with IgA nephropathy had an elevated serum IgA/C3 ratio than those with other glomerular diseases and the control subjects, with an area under the ROC curve of 0.776. An elevated serum IgA/C3 ratio was not found to significantly correlate with the pathological grade of renal biopsy samples in patients with IgA nephropathy.
CONCLUSIONIn the absence of renal biopsy findings, serum IgA/C3 ratio can help in the diagnosis of IgA nephropathy.
