The incidence of toileting problems is associated with the level of intellectual disability,and more common among the children with severe intellectual disability.This paper would review the classification,prevalence,consequences,origins of toileting problems,and also include the descriptions,assessment and practical considerations of behavioral interventions.

Objective To compare the efficacy of the emergency ESWL within 24 hours after the onset of renal colic and elective ESWL at 5 - 7 days after the onset of renal colic in the treatment for ureteral stones.Method From January 2008 to October 2009, 365 patients in the Second Hospital of Nanchang, with ureteral stones were admitted to our department for renal colic. They underwent emergency ESWL or elective ESWL with HK. ESWL- 108 energy electromagnetic shock wave lithotripter. Success rate of fragmentation, stone-free rate after 2 weeks of operation, pain recurrence rate, and complications were evaluated. The data were analyzed using SPSS 15.0. Results The success rate of fragmentation and the stone-free rate after 2 weeks of emergency ESWL were 96.76% and96.21%, respectively, which were higher than those (88.33% and 87.22%, respectively) of elective ESWL ( P ＜ 0. 05). The postoperative pain recurrence rate of emergency ESWL ( 4.32 % ) was lower than that (9.44%) of elective ESWL ( P ＜0.05). There was no difference of total complications between emergency ESWL (3.24%) and elective ESWL (2.78%) group (P ＞0.05). Conclusions Emergency ESWL is superior to selective ESWL and is the safe and effective method for the management of ureteral stones.

Chronic myeloid leukemia (CML) is a slowly progressing hematopoietic cell disorder. Sphingosine kinase 1 (SPHK1) plays established roles in tumor initiation, progression, and chemotherapy resistance in a wide range of cancers, including leukemia.However, small-molecule inhibitors targeting SPHK1 in CML still need to be developed. This study revealed the role of SPHK1 in CML and investigated the potential anti-leukemic activity of hirsuteine (HST), an indole alkaloid obtained from the oriental plant Uncaria rhynchophylla, in CML cells. These results suggest that SPHK1 is highly expressed in CML cells and that overexpression of SPHK1 represents poor clinical outcomes in CML patients. HST exposure led to G2/M phase arrest, cellular apoptosis, and downregulation of Cyclin B1 and CDC2 and cleavage of Caspase 3 and PARP in CML cells. HST shifted sphingolipid rheostat from sphingosine 1-phosphate (S1P) towards the ceramide coupled with a marked inhibition of SPHK1. Mechanistically, HST significantly blocked SPHK1/S1P/S1PR1 and BCR-ABL/PI3K/Akt pathways. In addition, HST can be docked with residues of SPHK1 and shifts the SPHK1 melting curve, indicating the potential protein-ligand interactions between SPHK1 and HST in both CML cells. SPHK1 overexpression impaired apoptosis and proliferation of CML cells induced by HST alone. These results suggest that HST, which may serve as a novel and specific SPHK1 inhibitor, exerts anti-leukemic activity by inhibiting the SPHK1/S1P/ S1PR1 and BCR-ABL/PI3K/Akt pathways in CML cells, thus conferring HST as a promising anti-leukemic drug for CML therapy in the future.
