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.

They were evaluated with Ashworth Assessment and manual muscle testing (MMT) 6 months after treatment. Results The scores of intervention group improved more significantly than those in control group （P<0.05）. 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 explore the effects of Omaha system-based nursing intervention on patients after percutaneous coronary intervention (PCI). Methods? Totally 200 patients receiving PCI in Ningbo First Hospital from February 2016 to November 2017 were selected using convenient sampling and divided into the control group (n=100) and the observation group (n=100) according to the random number table. Patients in the control group received conventional nursing care, while patients in the observation group received nursing care based on Omaha system. The incidence of postoperative vascular complications was evaluated between the two groups. Self-Depression Scale (SDS), Self-Anxiety Scale (SAS) and the nursing satisfaction questionnaire were used to evaluate the effects of intervention. Results? The incidence rate of postoperative vascular complications was lower in the observation group than in the control group (P＜ 0.05); the SAS and SDS scores of the observation group were lower than those of the control group (P＜0.05); and the satisfaction at discharge of the observation group was higher than that of the control group (P＜ 0.05). Conclusions? Omaha system-based nursing interventions can reduce the incidence rate of postoperative vascular complications, ameliorate patients' negative emotions and improve their satisfaction, which is worth promoting in clinical practice.

Objective:To establish an intelligent management system and explore its application in the management of high-value consumables in Interventional Operating Room.Methods:Supply and processing and distribution (SPD) combined with the intelligent management system was applied in the Intervention Center at Ningbo First Hospital of Zhejiang Province in October 2019. High-value consumables managed with traditional information management between October 2018 and September 2019 were included into the control group, while those managed with SPD combined with the intelligent management system from October 2019 to September 2020 were included into the observation group. The high-value consumable system and inventory compliance rate, average daily inspection time, average daily claim time, timely supply of consumables, return rate of unused consumables, and nurse satisfaction under the two different management modes were compared.Results:The coincidence rates of the high-value consumable system inventory and actual inventory in the observation group and the control group were 98.26% (226/230) and 85.21% (196/230) , respectively; the average daily inspection time, (67.44±1.42) min in the observation group was less than (108.00±2.51) min in the control group, and the average daily claim time, (53.41±5.24) min was less than (118.22±4.68) min in the control group; the total rate of untimely supply of consumables and unreturned unused consumables in the observation and control groups were 3.46% (138/3 986) and 20.86% (881/4 224) , respectively; and the satisfaction of nurses in the two groups were 93.75% (135/144) and 63.89% (92/144) . The differences between the two groups were all statistically significant ( P<0.05) . Conclusions:The construction and application of the intelligent consumable management system can effectively improve the standardization and refinement of the management of high-value consumables in the Interventional Operating Room, and reduce the operating cost of the department.

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 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.
