ObjectiveTo study the effect of Tetrax balance test and exercise on the balance function of stroke patients with hemiplegia. Methods50 stroke patients with hemiplegia and with disorder of balance function were divided into treatment group (25 cases) and control group (25 cases). The patients in both groups received regularly rehabilitation train and medical therapy. The treatment group was given balance train and motor function train responded to the analysis of the Tetrax balance assessment as well. They were evaluated with Berg balance scale, motor function of lower extreme in Fugl-Meyer Assessment (FMA) and activities of daily living (ADL) before and 4 weeks, 8 weeks, 12 weeks after treatment respectively. ResultsThere was no difference in balance function and motor function of lower extreme and ADL between treatment group and control group before treatment (P>0.05), but 4 week, 8 week, 12 week after treatment, there were significant improvement for balance function and motor function of lower extreme in both groups (P<0.01), and the treatment group improved more significantly than those of control group (P<0.05).ConclusionTexrax balance assessment can help understand the obstacle in balance function and formulate more suitable rehabilitation treatment.

Conclusion Motomed Gracile can facilitate the recovery of children with spastic cerebral palsy.

Objective To evaluate the BALB/c murine infective effects in different concentrations and different aerosol challenge times by Bordetella pertussis.Methods Four experiment groups according to different concentrations and different aerosol challenge times were designed.BALB/c murines were challenged by aerosol way.Group 1: 1010cfu/mL Bordetella pertussis challenge 15 min, group 2: 1010cfu/mL challenge 30 min, group 3: 109cfu/mL challenge 30 min, group 4: 1011cfu/mL challenge 30 min, using the normal saline challenge 30 min as control.At 0d,3d,7d,14d and 21d after challenge, the WBCs of all groups were measured and lung tissues were homogenized to calculate the bordetella pertussis clone in lung.Results After 3 days of challenge, WBCs in all groups were slightly increased.The WBCs of group 1, group 2, group 3 and group 4 were significantly increased after 7 days, with the average numbers of 8.52×109 per/L, 1.74×1010per/L, 1.15×1010per/L and 5×1010per/L, respectively.After 14 days, they were 1.77×1010per/L, 1.67×1010per/L, 1.27×1010per/L and 3.84×1010per/L respectively.WBCs in all groups were dramatically declined after 21 days.The WBC of negative control group had no obvious change during the whole process with the stable number of 3.4~7.0×109per/L.Bordetella pertussis were detected in lung of all experimental groups in each sampling point.The CFU in lung wase at peak at 7d or 14d after challenge, which was obviously decreased at 21d.Conclusion This aerosol challenge method can establish a bordetella pertussis infection mouse model successfully.

Objective:To evaluate the clinical significance of the coincidence test with 3D mirror image of unaffected side in the treatment of contralateral calcaneal fracture.Methods:A retrospective analysis was performed of the 35 patients who had been treated for single calcaneal fracture by coincidence test with 3D mirror image of unaffected side from January 2016 to June 2018 at Department of Trauma Orthopedics, The Sixth Hospital of Ningbo. They were 29 males and 6 females with an average age of 44 years (from 18 to 71 years). By Sanders classification, 19 cases were type Ⅱ and 16 cases type Ⅲ. CT scan and reconstruction of both calcaneuses was performed. The image of unaffected calcaneus was mirrored by Mimics software to guide virtual treatment of contralateral calcaneal fracture. Preoperatively the virtual bilateral calcaneuses and the reduced calcaneus were 3D printed to guide the actual operation. The coincidence test with 3D mirror image of unaffected side was used to evaluate fracture reduction after operation. Postoperative parameters such as B?hler Angle, Gissane Angle, calcaneal width, and coincidence of the affected calcaneal bone were recorded at 12 months after surgery. The clinical outcomes were assessed by American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score and visual analogue scale (VAS) score.Results:In this cohort, operation time averaged 43.9 min (from 30 to 55 min), time from admission to operation 3.6 d (from 0 to 14 d), and hospital stay 6.3 d (from 3 to 11 d). The patients were followed up for an average of 18.8 months (from 13 to 24 months). All patients achieved bone union after an average of 17 weeks (from 12 to 26 weeks). Re-collapse of subtalar articular surface, talocalcaneal joint fusion, loss of calcaneal height or length, and calcaneal width increase were observed in none of the patients. The VAS scores averaged 2 (from 0 to 4), and the AOFAS scores 93.3 (from 76 to 98). The total coincidence was 95.2%±3.5%. Spearman test indicated a positive correlation between postoperative total coincidence and AOFAS score ( ρ=0.588, P<0.05). Conclusion:The coincidence test with 3D mirror image of unaffected side can be used to treat contralateral calcaneal fracture, with advantages of reduced surgical time, increased surgical accuracy and fine clinical outcomes.

Objective To investigate the effects of different concentrations and adsorption methods of aluminum hydroxide adjuvant produced by different manufacturers on the immunogenicity of the diphtheria-tetanus-acellular pertussis and inactivated poliovirus combined vaccine ( DTaP-sIPV) . Methods Five anti-gens of DTaP were adsorbed onto different concentrations (0. 42 mg/ml, 0. 47 mg/ml and 0. 52 mg/ml) of aluminum hydroxide from different manufacturers through sequential and separate adsorption. Adsorbability, anti-pertussis toxin ( PT)/filamentous hemagglutinin ( FHA)/pertactin ( PRN)/diphtheria toxoid ( DT)/tet-anus toxoid ( TT) antibodies and the potency of vaccines were detected. Results The adsorbability of alu-minum hydroxide adjuvant slightly decreased with the reduction of concentration. No significant difference in potency and antibody level was observed between sequential and separate adsorption. Moreover, no signifi-cant difference in antibody level was observed between vaccines prepared with aluminum hydroxide adjuvant produced by General Chemical Corp and our institute. Conclusion Aluminum hydroxide adjuvant produced by our institute at the concentration of 0. 52 mg/ml and separate adsorption method are suitable for prepara-tion of DTaP-sIPV.

Objective: To understand sensory characteristics and its correlation with behavioral problems among children with autism spectrum disorder (ASD), so as to provide reference basis for early diagnosis and comprehensive intervention of ASD children. Methods: Using cross sectional survey, 193 ASD children trained by Nantong rehabilitation institutions were recruited from September 2021 to February 2022. All children were investigated with the Short Sensory Profile (SSP) and Parent Symptom Questionnaire (PSQ). Results: Among the 193 ASD children, 106 (54.9%) children had abnormal sensory characteristics, including 45 (23.3%) with possible abnormalities and 61 (31.6%) with obvious abnormalities. The abnormal rate of auditory filtering was the highest in the seven dimensions, reaching 85.0%, followed by low strength/weakness, motor sensitivity, taste/smell sensitivity, low response/seeking sensation, vision/hearing sensitivity and tactile sensitivity. The total incidence of sensory abnormalities was 93.3%. There were significant differences in six dimensions of PSQ scale scores of ASD children with different degrees of sensory abnormalities, including conduct problems, learning problems, psychosomatic disorders, impulsive hyperactivity, anxiety and hyperactivity index ( H =38.89, 38.90, 19.53, 46.34, 34.54, 54.90, P <0.01). With the aggravation of sensory abnormalities in children with ASD, the scores of all dimensions of the PSQ scale increased significantly. The total score of SSP was negatively correlated with the six dimensions of conduct problems, learning problems, psychosomatic disorders, impulsive hyperactivity, anxiety and hyperactivity index in PSQ ( r =-0.53, -0.50, -0.32, -0.55, -0.43, -0.61, P <0.01). Conclusion ASD children generally have sensory abnormalities, which coincide with severity of behavioral problems. There is a positive correlation between sensory abnormalities and behavioral problems in ASD children. More attention should be paid to the abnormal sensory characteristics of children with ASD in the future diagnosis and treatment process.

Objective:To understand the sensory characteristics of children with autism spectrum disorder (ASD), and to explore its relationship with the clinical symptoms and to provide a reference basis for early diagnosis and intervention treatment of ASD.Methods:A cross-sectional survey was conducted to collect 216 children diagnosed with ASD according to DSM-5 from September 2021 to December 2021.All children were investigated with short sensory profile (SSP), autism behavior checklist (ABC) and social response scale (SRS). SPSS 21.0 was used for statistical analysis and the correlation between sensory characteristics and clinical symptoms of ASD children was analyzed by Pearson correlation.Results:The results showed that 120 of 216 with ASD children had abnormal SSP total score, with an abnormal rate of 55.6%.Among the seven dimensions, the abnormal rate of auditory filtering was the highest, reaching 83.8%, followed by low strength/weakness(60.2%), motor sensitivity(43.5%), low response/sensation seeking(39.8%), taste/smell sensitivity(37.5%), vision / hearing sensitivity(27.8%) and tactile sensitivity(17.6%), and the total incidence of paresthesia was 92.1%.There were significant differences in the total score of ABC and the five dimensions of sensation, communication, body movement, language and life self-care of ASD children with different sensory characteristics ( F=39.15, 39.99, 46.02, 29.18, 50.98, 51.76 respectively, all P<0.01). There were significant differences in the total score of SRS and social perception, social cognition, social communication, social motivation among ASD children with different sensory characteristics ( F=19.33, 29.47, 24.82, 29.68, 31.48, 39.86 respectively, all P<0.01). With the aggravation of sensory abnormalities, the total scores of ABC and SRS and the scores of each dimension increased.The total score of SSP was negatively correlated with the scores of sensation, communication, body movement, language, self-care and the total score of ABC ( r=-0.613, -0.631, -0.643, -0.558, -0.657, -0.679 respectively, all P<0.01). The total score of SSP was negatively correlated with social perception, social cognition, social communication, social motivation, autism behavior and the total score of SRS ( r=-0.440, -0.527, -0.504, -0.522, -0.542, -0.595 respectively, all P<0.01). Conclusion:Sensory abnormalities are common in ASD children, and with the aggravation of sensory abnormalities, the core symptoms and behavioral performance of ASD children are more obvious and positively correlated.

Tongue diagnosis is one of the diagnostic methods of Traditional Chinese Medicine (TCM), but its development has always been restricted by the lack of objective quantitative indicators. With the rapid development of computer technology and the advent of the algorithm era, the modernization of TCM tongue diagnosis has gradually become a hot research spot. This paper annalyses the literature and related patents of the modernization of tongue diagnosis and summarizes the R&D progress and application of tongue diagnosis as well as related instruments. It is found that domestic and foreign scholars focus on tongue diagnosis related research and attach importance to the formulation of relevant international standards. Tongue collection and analysis technology continues to develop; tongue diagnostic instruments are also gradually enriched. At present, their applications are extended to family self-use, but they are still mainly used in teaching, scientific research and other fields, involving the clinical efficacy evaluation of TCM, clinical case classification and health management, and there is still much room for development. In the future, we should strengthen the communication between multi-regional research centers, promote the communication among talents in different fields, constantly make up for the deficiencies and promote the development of tongue diagnosis research.

Objective:To observe the effect of speech training based on mirror neuron theory on children with functional articulation disorder (FAD).Methods:Fifty children with FAD were randomly divided into a training group and a control group, each of 25. Both groups received 30 minutes of conventional speech training 5 times a week for 24 weeks, while the training group was additionally given 20 minutes of speech training based on mirror neuron theory simultaneously. Before and after the intervention, both groups were evaluated using the articulation speech ability assessment scale and the oral motor ability assessment scale.Results:Before the treatment, there were no significant differences between the 2 groups in any of the measurements. After the treatment, significant improvement was observed in all of the measurements for both groups, but at that point the training group′s articulation, motor ability of the lower jaw, tongue and lips were all significantly superior to the control group′s averages.Conclusions:Speech training based on mirror neuron theory can significantly improve the articulation, intelligibility and oral motor functioning of children with functional articulation disorder.

Objective: To explore the impact of maternal anxiety during pregnancy on social emotional development of toddlers aged 1-3 year old, so as to provide references for scientific early parenting and early intervention for toddlers with social emotional difficulties. Methods: From September 2022 to March 2023, a total of 815 toddlers aged 1-3 who underwent physical examinations and their mothers at Nantong Maternal and Child Health Hospital were enrolled. The Chinese Infant Toddler Social and Emotional Assessment (CITSEA) was used to evaluate the social emotional ability among toddlers. Maternal anxiety evaluated using the Self rating Anxiety Scale (SAS) during prenatal visit was collected. Results: The average scores on the externalizing, internalizing, dysregulation and competence domains of the CITSEA were (49.40±9.48,47.42±9.60,48.67± 10.15 , 50.07± 10.20), respectively. Among boys, the score of externalizing domain (50.89±9.45) was higher than that of girls (48.76± 9.50 ), while the score of competence domain (49.22±10.30) was lower than that of girls (51.17±9.84), and the differences were statistically significant( t =2.10, -3.03, P <0.05). The detection rates of abnormalities in the externalizing, internalizing, dysregulation, and competence domains were 7.36%, 7.12%, 7.61%, and 7.24%, respectively. Among them, boys (8.43%,6.32%, 7.96 %,7.49%) and girls (6.19%, 7.99 %,7.22%,6.96%) showed no statistical differences ( χ 2=1.50, 0.85, 0.16, 0.09, P >0.05). There were significant differences in externalizing domain scores（47.77±9.52，49.56±8.95，52.51±9.77） and competence domain scores（51.70±10.38，49.65±10.05，46.68±10.03） among toddlers of different maternal anxiety（normal, mild, moderate to severe） （ F =7.05,7.10, P <0.01）. There were significant differences in the abnormal detection rate of externalizing domain （4.81%，7.54%，11.17%） and competence domain（4.81%，6.96%，11.73%）（ χ 2=6.60，7.98， P ＜0.05）. Conclusion Maternal anxiety during pregnancy has a negative impact on the social emotional development among toddlers. In order to improve social emotional development of toddlers, multidimensional social support and education during pregnancy should be carried out.
