ObjectiveTo investigate the effect of daily living activity training on the self-care ability of children with cerebral palsy.Methods Sixty children with cerebral palsy were equally divided into control group and observation group. The former group were managed with rehabilitative therapy and the latter were given ADL training consecutively for 6 months apart from rehabilitative therapy.The two groups were compared in terms of score on ADL after 6 months treatment.Results There was no difference in the score on activities of daily living between the two groups before intervention (P>0.05),but the score after treatment in the obsertation group was significantly higher than that of the control group (P<0.01).Conclusion The ADL training is effective for improving the self-care ability of children with cerebral palsy and promoting the rehabilitation of children.

Objective To investigate the perception of Mandarin's tones by children with speech development disorders so as to provide a theoretical basis for clinical rehabilitation.Methods Thirty children with speech development disorders (DPDs) aged 4 to 6 were matched with 30 healthy counterparts as a control group.Both groups underwent the tone perception experiment,which included tone identification and discrimination tasks.The speech stimuli were 11 computer-simulated voices expressing a continuum of sounds from Mandarin speech ranging from /bá/ to /bà/.The two groups were compared in their ability to identify and differentiate the tones.Results Both groups showed typicalS-shaped identification curves in a category pattern.The category boundaries of the control group were between stimulus steps 6 and 7,significantly different from those of the experimental group where the boundary fell between stimulus steps 5 and 6.On the distinguishing curve,both groups presented obvious peak values.The stimulus steps of the peaks and the crossing points of the identification curves were consistent.In addition,the average ahsolnte value (b1) of the identification curve and the peaks' degree of steepness (DP) of the DPD group's distinguishing curve were significantly lower than those of the control group.At the same time,the average boundary width (Wcb) was significantly higher than that of the control group.Conclusion Children with speech development disorders perceive Mandarin tones with categories different from those of normal children.They may have difficulty in perceiving tones,which might be an important factor leading to pronunciation errors.

Objective:To investigate the short term efficacy of laparoscopic assisted transanal total mesorectal excision (taTME) for low rectal cancer.Methods:The prospective study was conducted. The clinicopathological data of 80 patients who underwent laparoscopic assisted taTME for low rectal cancer in 8 medical centers，including 27 cases in the First Affiliated Hospital of Jilin University，16 cases in the Daping Hospital of Army Medical University，15 cases in the Beijing Friendship Hospital of Capital Medical University，10 cases in the Peking University Cancer Hospital，7 cases in the Peking Union Medical College Hospital of Chinese Academy of Medical Sciences，2 cases in the Peking University People′s Hospital，2 cases in the Liaoning Cancer Hospital Institute，1 case in the Ruijin Hospital of Shanghai Jiaotong University School of Medicine，from August 2017 to September 2018 were collected. Observation indicators：(1) clinical data of enrolled patients；(2) surgical situations；(3) postoperative histopathological examination；(4)postoperative complications and hospitalization. Measurement data with skewed distribution were represented as M(range). Count data were described as absolute numbers and (or) percentages. Results:(1) Clinical data of enrolled patients：a total of 80 patients were selected for eligibility. There were 59 males and 21 females，aged from 53 to 79 years，with a median age of 61 years. (2）Surgical situations：all 80 patients underwent surgery successfully，including 73 cases undergoing low anterior resection，4 cases undergoing Hartmann operation，1 case undergoing intersphincteric and abdominoperineal resection，1 case undergoing other operations and 1 case missing operation information. Nineteen of the 80 patients underwent transabdominal and transanal operations simultaneously. The operation time of 80 patients was 255 minutes (range，211?305 minutes). Of 80 patients，77 cases had the volume of intraoperative blood loss ≤500 mL，3 cases had the volume of intraoperative blood loss >500 mL，44 cases underwent instrumental anastomosis，24 cases underwent manual anastomosis，12 cases were missing anastomosis information，66 cases had specimens been taken out through anus，2 cases had specimens been taken out through Pfannens-tiel incision，10 cases had specimens been taken out through other ways，2 cases were missing the information of specimens removal ways，57 cases underwent preventive stoma，32 cases under-went anal canal indwelling，30 cases underwent free of splenic flexure and 2 cases were converted to open surgery. (3) Postoperative histopathological examination：of 80 patients，68 cases had the integrity of mesorectal specimens with complete，5 cases had the integrity of mesorectal specimens with near complete，1 case had the integrity of mesorectal specimens with not complete，6 cases were missing the information of integrity of mesorectal specimens，1 case had rectal perforation，1 case had positive circumferential margin and 1 case had positive distal margin. The number of lymph node dissected and diameter of tumor were 12(range，9?16) and 3.0 cm(range，1.9?4.0 cm) of 80 patients. Four of 80 patients achieved pathological complete remission. Cases with tumor stage as T0 stage，Tis stage，T1 stage，T2 stage，T3 stage or T4 stage of the pT staging，cases with tumor stage as N0 stage，N1 stage or N2 stage of the pN staging，cases with tumor stage as M0 stage or M1 stage of the pM staging were 4，2，11，24，35，4，55，21，4，75，5 of 80 patients. (4) Postopera-tive complications and hospitalization：8 of 80 patients underwent anastomotic leakage，including 2 cases with grade A anastomotic leakage，4 cases with grade B anastomotic leakage and 2 cases with grade C anastomotic leakage.Seven of 80 patients underwent intestinal obstruction. The 2 cases with grade A anastomotic leakage were improved after symptomatic drug treatment，the 4 cases with grade B anastomotic leakage were improved after treatment with antibiotics or catheter drainage and the 2 cases with grade C anastomotic leakage were improved after operation. The duration of hospital stay of 80 patients was 14 days(range，11?21 days). No patient died during hospitalization.Conclusion:Laparoscopic assisted taTME for low rectal cancer is safe and feasible，which has a good short term efficacy.
