OBJECTIVEWe aim to explore the central auditory nervous system (CANS) functioning in children with nonsyndromic cleft palates by analyzing the auditory evoked potentials and event-related potentials (ERP).

METHODSA total of 34 children with nonsyndromic cleft palates were recruited as subjects, and 27 normally developed children were selected as the normal controls. Auditory brainstem response (ABR), middle latency response (MLR), and mismatch negativity (MMN) of ERP were selected as indices to observe the function of CANS in children in both groups.

RESULTSAstatistically significant difference between the groups was obtainedin the MMN recording (F = 227.69, P < 0.01), whereas no significant group differences were obtained in the ABR and MLR results (P > 0.05). Children with nonsyndromic cleft palates showed diminished MMN responses compared with the normal controls, whereas ABR and MLR were within the normal range.

CONCLUSIONChildren with nonsyndromic cleft palates are at risk of central auditory discrimination dysfunction. The significant abnormal event-related potentials recorded in children with cleft palates suggest that the dysfunction of CANS maybe located at the cortical level and normal function of CANS was located at the brain stem and sub-cortical level.

Objective To evaluate the efficacy and safety of diacerhein in the treatment of patients with knee osteoarthritis.Methods The efficacy and safety of diacerhein was randomly investigated in 42 pa- tients with knee osteoarthritis using parallel group methodology and a double-dummy technique to ensure dou- ble blind status with respect to diacerhein and control drugs diclofenac.Results Significant changes were ob- served in 20 meters walk pain,knee joint tenderness scale,WOMAC index scale,5F-36 health survey,knee joint swelling scale,compared with baseline(P＞0.05)in both diacerhein and diclofenac group respectively.No difference was found between diacerhein group and diclofenae group.The patient global assessment and physi- cian's global assessment were similar in diacerhein group and diclofenac group(P＞0.05).The side effect was similar in two groups.All of these side effects in gastrointestinal tract appeared to be transient.Conclusion Diacerhein can effectively relieve pain and swelling of knee osteoarthritis,and provides us a new effective and safe approach for treating knee osteoarthritis.

Objective To census the preoperative prevalence rate of deep venous thrombosis (DVT) and to evaluate the risk factors of DVT in senile osteoporotic hip fractured patients.Methods The object of study were patients aged 60 and above, and osteoporotic hip fracture by low energy injury in 2013.Based on medical records, all the patients with osteoporotic hip fracture were evaluated the signs and symptoms of DVT in 24 h, D-dimer test and underwent Doppler ultrasound screening of bilateral venous system in lower extremity after admission, and all the patients received preoperative prophylactic anticoagulation.Patients with popliteal and proximal level thrombus or floating thrombus underwent inferior vena cava (IVC) filter insertion.Outcome measures: age, gender, fracture type, D-dimer value in 24 h preoperatively, occurrence time of DVT and region, grade of preoperative American Society of Anesthesiologists, preoperative medical diseases.Results 702 of 946 hip fracture inpatients were comprised in this retrospective study.All were not founded any symptom or signs of DVT.All patients were took preoperative Doppler ultrasound screening and the results as follows: 36 of 302 patients (11.9％) with femoral neck fracture were proved preoperative thrombosis(13 male, 23 female), the average age was 72.7 year-old(range from 62-90 year-old), on the same side as the fractured hip in 31 patients, bilateral thrombosis in 5 patients.74 of 400 patients (18.5％) with intertrochanteric fracture were proved preoperative thrombosis(38 male, 36 female), the average age was 76 year-old (range from 60-95 year-old), on the same side as the fractured hip in 68 patients, bilateral thrombosis in 6 patients.The most prevalence rate of DVT were in the first day after osteoporotic hip fracture, 15 patients (41.7％) with femoral neck fracture and 38 patients (51.40％) with intertrochanteric fracture.There were more proximal level and multiple level involment thrombosis over 5 days after injury.The most thrombosis were proven at calf and popliteal vein.Conclusion The prophylaxis of DVT should be started even in the emergency department in senile patient with osteoporotic hip fracture.To avoid the risk factors, early surgery and early postoperative mobilization will be effective.

Objective To establish a method for determination of 2-chloroacetamide in cosmetics. Methods The gas chromatography method had been developed for determination of 2-chloroacetamide in cosmetics. Samples were solved with ethanol treated with ultrasonic homogenization centrifuge separated by HP-INNWax column determined by FID. Results The 2-chloroacetamide concentration had a better linear range in the range of 0.0-10.0 mg/ml. The minimum detection limit was below 0.01 ?g. The relative standard deviation was less than 5.6% and the recovery rates were 90%-100% respectively. Conclusion This method is simple fast and sensitive.

Objective To investigate the effect of MOTOmed intelligent training system training on balance and lower limb motor function in stroke patients. Methods 120 stroke patients were randomly divided into observation group (n=60) and control group (n=60) according to the random number table. Both groups were treated with routine rehabilitation training, the observation group received MOTOmed intelligent training system in addition. They were evaluated with Fugl-Meyer assessment (FMA), Functional Ambulation Category (FAC), Barthel index (BI), Motricity index (MI-L), modified Ashworth scale (MAS) and Berg balance scale (BBS) before and 4, 8, 12 weeks after treatment. Results There was no difference in the score of FMA, BI, MI-L, BBS, MAS, FAC and the maximum walking speed, stride length and stride frequency between 2 groups before treatment (P>0.05). The scores of FMA, BI, MI-L, BBS, FAC and the maximum walking speed stride length and stride frequency increased in the observation group and there was a uptrend 4 weeks, 8 weeks and 12 weeks after treatment (P<0.05). The score of MAS decreased in the observation group and there was a downtrend after treatment (P<0.05). All the indexes were better in the observation group than in the control group (P<0.05). Conclusion MOTOmed training system combined with routine rehabilitation training can improve the balance and lower limb motor function in stroke patients.

ObjectiveTo investigate the therapeutic effect of genciclovir on cytomegalovirus (CMV) infection of children with cerebral palsy (CP).Methods36 CP children with CMV infection were randomly divided into treatment group and control group with 18 cases in each group. Children of treatment group were treated by genciclovir with 5 mg/kg i.v. drip q l2 h for 14 days at inductive phase and 7.5 mg/kg i.v. drip qod for 6 weeks at maintain phase. Cases of control group were treated by acyclovir with 5 mg/kg i.v. drip q 8 h for 14 days at inductive phase and 7.5 mg/kg i.v. drip q l2 h for 6 weeks at maintain phase. CMV-DNA contents in urine of two groups were measured before and after treatment.ResultsCMV-DNA contents in urine of two groups were not different before treatment (P>0.05). For control group, CMV-DNA contents were also not different before and after treatment. For treatment group, CMV-DNA contents after treatment significantly decreased compared with pre-treatment and that of control group after treatment (P<0.05).ConclusionGenciclovir is effect and safety for CMV infection of CP children.

ObjectiveTo investigate whether the Toxoplasma infection is the risk factor of occurrence of children cerebral palsy.Methods236 children with cerebral palsy and 428 normal children were included. Children were laminated to 4 groups by age:-3 months,-6 months,-9 months,-12 months. Final diagnosis was made by one or more finding following: plasma Toxoplasma DNA(TOX-DNA), plasma Toxoplasma circulating antigen(TOX-CAG), plasma Toxoplasma IgM(TOX-IgM), exclusion other congenital infected diseases.ResultsThe OR and 95%CI were 10.13,3.74-27.42 in -3 months,7.71,2.45-24.28 in -6 months,8.84,1.85-42.31 in-9 months(P<0.01 respectively), and 4.30, 0.83-22.28(P>0.05)in -12 months. ConclusionThere is correlation between the Toxoplasma infection and the children cerebral palsy; the earlier Toxoplasma infection, the greater the risk of cerebral palsy. Congenital Toxoplasma infection may be one of important factors in children cerebral palsy.
