Objective To explore the deficiency of upper limb movement in children with autism and its related factors. Methods 30 au-tism children aged 7-13 years old, and 30 healthy children aged 7-8 years from February to May, 2014 were enrolled. Their range of motion, comprehensive strength and cooperation, endurance, and muscular tension were tested. Results All the indexes of autism children lagged be-hind the healthy children (P<0.01), expect the muscular tension of the right upper limb (P>0.05). The endurance of boys was better than girls (P=0.020), and there was no difference in other aspects between them (P>0.05). The type of autism for more upper limb movement cor-related with obstruction of Jianjing acupoint (GB21) (r=0.515, P=0.013), and was significantly different with the type of less limb move-ment (χ2=8.533, P=0.003). Conclusion Compared with healthy children, the joint motion is relatively flexible, but lack of strength, and with poor persistence and unbalance development between left and right upper limbs. Motor rehabilitation should be conducted according to their movement features and the condition of meridian.

CONCLUSIONS:Cancer pain cataplasm has good release and transdermal performance. Its transdermal kinetics is in line with Higuchi equation.

Based on carbon metabolic pathway analysis of Escherichia coli MG1655, an aerobic succinate fermentation platform was constructed by knocking out five genes (ptsG, poxB, pta, iclR and sdhA), which was named E. coli QZ1111. Flask cultivation results showed that E. coli QZ1111 could accumulate succinate with a concentration of 26.4 g/L under aerobic conditions. The byproduct acetate was only 2.3 g/L. The production ratio of succinate and acetate reached 11.5:1.

Objective:To observe the effect of combining transcranial direct current stimulation (tDCS) with functional electrical stimulation-assisted cycling (FES-cycling) on lower limb motor function early after a stroke.Methods:Thirty-seven survivors of a recent stroke were divided into a tDCS treatment group ( n=18) and a pseudo-stimulation group ( n=19). While receiving routine rehabilitation training and clinical drug treatment, the tDCS treatment group also cycled in response to functional electrical stimulation while simultaneously receiving tDCS anode stimulation of the motor cortex M1 area. The pseudo-stimulation group followed the same protocol but with the tDCS stimulation inactivated. Both groups were treated for 20min daily, 5 days weekly for 4 weeks. Before and after the 4 weeks of treatment, the lower limb motor function, walking ability and ability in the activities of daily living of both groups were evaluated using the Fugl-Meyer assessment scale for the lower extremities (FMA-LE), the timed up and go test (TUGT) and the modified Barthel index (MBI) respectively. Transcranial magnetic stimulation was used to detect each subject′s cerebral cortex motor threshold (CMT) , cortical latency (CL) and central motor conduction time (CMCT) as well as the amplitude (Amp) of the motor evoked potential of the lower limb primary motor cortex (M1 area). Results:After 4 weeks of treatment, the average FMA-LE and MBI scores and TUGT times of the two groups had improved significantly compared with those before treatment. The average FMA-LE score and TUGT time of the tDCS group were significantly better than those of the pseudo-stimulation group. The average CMT, CL and CMCT in both groups were significantly lower than those before the intervention, while the average Amp had increased significantly, but there were significant differences in the average CMT, Amp, CL and CMCT between the two groups after the 4 weeks of treatment.Conclusions:Transcranial direct current stimulation combined with cycling assisted by functional electrical stimulation can effectively stimulate excitability in the motor cortex soon after a stroke. That should promote the recovery of nerve activity and lower limb function.

Objective To observe the therapeutic effect of low dose tolvaptan combined with furosemide in ederly patients with CHF and diuretic resistance (DR).Methods Eighty-five elderly patients with CHF and DR were divided into observation group (n=43) and control group (n=42).The patients in observation group were treated with cardiotonics and hypotensors plus oral tolvaptan (15 mg/d) combined with intravenous furosemide (40 mg/d).The therapeutic effect of low dose tolvaptan combined with furosemide was assessed.Results The average urinary volume was larger,and the LVEDV was significantly lower in two groups after treatment than before treatment (P＜0.05).The urinary volume was significantly larger while the LVEDV was significantly lower in observation group than in control group (2.89±0.87 L/d vs 2.43±0.49 L/d,P=0.01;103.6±21.5 ml vs 116.7±24.3 ml,P=0.01).The total effective rate was significantly higher in observation group than in control group (86.0％ vs 71.4％,P=0.01).Conclusion Low dose tolvaptan combined with furosemide can effectively improve the DR and therapeutic effect in elderly CHF patients,and is thus worth popularization in clinical practice.

Urinary incontinence is a common disease of women. Approximately there are two billion patients with urinary incontinence globally, SUI accounts for almost 1/2 of urinary incontinence. Stress urinary incontinence not only affects women′s health and limits the patients′ daily behavior and physical activity, resulting in anxiety, depression, etc. In view of the high prevalence of SUI, the high impact rate and low rate of diagnosis and treatment, the clinical medical professionals need to understand the relevant contents of SUI. This review will summarize the risk factors about stress urinary incontinence and the development of pelvic floor muscle rehabilitation. We hope to provide reference for clinical practice.

Objective To explore the application effects of hip muscle training on female patients with stress urinary incontinence (SUI).Methods Totally 48 female patients with mild to moderate SUI were recruited in this study from the Second Hospital of Hebei Medical University from January to November 2015 by using purposive sampling method. According to the random number table,the participants were divided into the intervention group (n=24) and the control group (n=24). Patients in the intervention group received resisted hip muscle exercise,including the hip internal rotation and hip external rotation. Patients in the control group received conventional pelvic floor muscle exercise (PFME). The intervention lasted for 12 weeks,and the application effects were evaluated by the questionnaire of urinary incontinence quality of life (I-QOL) and the urine pad test before the intervention,eight weeks,and 12 weeks after the intervention.Results After the intervention,the urine leakage was significantly decreased,and the I-QOL score was increased (P<0.05). Although the urine leakage had no statistical difference between two groups (P>0.05),the total I-QOL scores and the scores of social barriers dimension were higher inr the intervention group compared with that in the control group (P<0.05). But on the dimension of limited behavior and the psychological impact,there were no statistical differences between two groups (P>0.05).Conclusions Resisted hip muscle training can effectively decrease the urine leakage and improve the quality of life of female patients with mild to moderate SUI.

Objective:To analyze the epidemiological characteristics of human respiratory syncytial virus (HRSV) in cases of febrile respiratory syndrome in China from 2010 to 2020.Methods:Based on the sub-project of the National Science and Technology Major Project for Infectious Disease Prevention and Control "Infectious Disease Monitoring Technology Platform", active monitoring of febrile respiratory syndrome cases was conducted in sentinel hospitals in 31 provinces across China (excluding Hong Kong, Macau, and Chinese Taiwan) from January 2010 to December 2020, resulting in the inclusion of 191 441 cases. Clinical specimens of monitored cases were screened for HRSV nucleic acid, and the differences in HRSV detection rates among different age groups, regions, and time periods were analyzed using the χ 2 test/Fisher exact probability method. Results:Among the 191 441 cases of febrile respiratory syndrome in China from 2010 to 2020, the age group M ( Q1, Q3) was 9 (2, 40) years old, with 83 773 cases (43.8%) in the <5 years old group. There were 113 660 males, with a male-to-female ratio of 1.5∶1.0. There were as many as 105 508 cases (55.2%) of scattered children and preschool children. About 70 565 cases (36.9%) lived in the northern region. There were 13 858 HRSV positive cases, with a total positive rate of 7.2%. The positive rate of HRSV detection in the northern population was 5.7% (4 004/70 565), which was lower than that in the southern population (8.2%, 9 854/120 876), and the difference was statistically significant (χ 2=407.4, P<0.001). HRSV was detected in all age groups, with the highest positive rate of 23.9% in the <6 months age group. The month with the highest positive rate was December, and autumn and winter were the main epidemic seasons. Both northern and southern HRSV subtypes were mainly infected with type A, with a low proportion of mixed infections of type A and type B. Conclusion:HRSV is a common pathogen causing respiratory infections in children from 2010 to 2020. It can be detected throughout the year and shows the main peak of prevalence in autumn and winter. The HRSV strain is mainly classified as a type A infection.
