OBJECTIVE: To analyze the principle mechanism of the arcus plantaris and its clinical application. METHODS: The states of forces sustained by the arcus plantaris were analyzed and calculated according to the mechanism of the quadratic parabolic arch. RESULTS: The aponeurosis plantaris corresponded to the pull rod of the arcus plantaris. The medial and lateral longitudinal arches formed by the pedal bones were stable with the rod, but unstable without the rod. In the latter condition, on loading, the force sustained by the parabolic arch became a force sustained by a simple beam, and the arcus plantaris tended to disappear and to be flattened. Clinically, 240 feet with talipes equinus were treated with triple arthrodesis. In 34 out of the reexamined 156 feet, the aponeurosis plantaris was cut in addition to the triple arthrodesis and was immobilized with cast for 3 months. One or two years later, their arcus plantaris disappeared, pain developed when walking, and some of them walked with the midtarsal joint against the ground. Then, the triple arthrodesis and shortening of the aponeurosis plantaris were applied on 18 cases, and osteotomy of the calcaneus and reconstruction of the aponeurosis plantaris were made on 10 cases and satisfactory effects were obtained. CONCLUSIONS: In order to achieve satisfactory therapeutic effects of the triple arthrodesis, we should reestablish the arcus plantaris and accurately treat the aponeurosis plantaris for the balance of the surrounding muscle force.

ObjectiveTo develop and preliminarily apply a dynamic scoring information system for critically ill patients to optimize the management system for critically ill patients. Methods? Totally 55 risk factors of three groups were selected based on Acute Physiology and Chronic Health Evaluation Scoring System, Tiss-28 Scoring System 2, critical value and expert consensus and included in the information platform, which was connected to the hospital's information and data system. A dynamic scoring system was designed and developed independently. The system consisted of two modules: alarm and clinical decision-making. An operation protocol was made by the Department of Nursing and included into the nursing management system to ensure that the system could run effectively. Data of inpatients in Tenth People's Hospital of Tongji University from October 2015 to October 2017 was selected. The disease recognition of the dynamic scoring system and the existing MEWS alarm and scoring system and the success rate of treatment in critically ill patients before and after the dynamic scoring system was introduced were compared. Results? The area under receiver operating characteristic curves (AUC-ROC) of the dynamic scoring system was 0.947(95%CI 0.930-0.964), which showed higher recognition of critical illness compared with the MEWS alarm and scoring system (P＜0.05). After the dynamic information system was introduced, the success rate of treatment in critically ill patients was 68.61%, which was higher than that before it was applied (χ2=10.046; P=0.002). Conclusions? The dynamic scoring system can accurately evaluate patients' disease and provide digital data and a list of clinical decisions for nurses, thus improving the success rate of treatment in critically ill patients and enhancing nurses' clinical decision-making ability.

Objective: To explore the influence of three-level collaboration network of pediatric burns in Anhui province on treatment effects of burn children. Methods: The data of medical records of pediatric burn children transferred from Lu′an People′s Hospital and Fuyang People′s Hospital to the First Affiliated Hospital of Anhui Medical University from January 2014 to December 2015 and January 2016 to September 2017 (before and after establishing three-level collaboration network of pediatric burns treatment) were analyzed: percentage of transferred burn children to hospitalized burn children in corresponding period, gender, age, burn degree, treatment method, treatment result, occurrence and treatment result of shock, and operative and non-operative treatment time and cost. Rehabilitation result of burn children transferred back to local hospitals in 2016 and 2017. Data were processed with t test, chi-square test, Mann-Whitney U test, and Fisher′s exact test. Results: (1) Percentage of burn children transferred from January 2014 to December 2015 was 34.3% (291/848) of the total number of hospitalized burn children in the same period of time, which was close to 30.4% (210/691) of burn children transferred from January 2016 to September 2017 (χ²=2.672, P>0.05). (2) Gender, age, burn degree, and treatment method of burn children transferred from the two periods of time were close (χ²=3.382, Z=-1.917, -1.911, χ²=3.133, P>0.05). (3) Cure rates of children with mild, moderate, and severe burns transferred from January 2016 to September 2017 were significantly higher than those of burn children transferred from January 2014 to December 2015 (χ²=11.777, 6.948, 4.310, P<0.05). Cure rates of children with extremely severe burns transferred from the two periods of time were close (χ²=1.181, P>0.05). (4) Children with mild and moderate burns transferred from the two periods of time were with no shock. The incidence of shock of children with severe burns transferred from January 2014 to December 2015 was 6.0% (4/67), and 3 children among them were cured. The incidence of shock of children with severe burns transferred from January 2016 to September 2017 was 3.9% (2/51), and both children were cured. The incidences and cures of shock of children with severe burns transferred from the two periods of time were close (χ²=0.006, P>0.05). Incidence of shock of children with extremely severe burns transferred from January 2014 to December 2015 was 57.1% (32/56), significantly higher than that of burn children transferred from January 2016 to September 2017 [34.5% (10/29), χ²=3.925, P<0.05]. Shock of 25 children with extremely severe burns transferred from January 2014 to December 2015 were cured, and shock of 9 children with extremely severe burns transferred from January 2016 to September 2017 were cured. The cures of shock of children with extremely severe burns transferred from the two periods of time were close ( χ²=0.139, P>0.05). (5) Time of operative treatment of children with moderate, severe, and extremely severe burns transferred from January 2014 to December 2015 was obviously longer than that of burn children transferred from January 2016 to September 2017 (t=2.335, 2.065, 2.310, P<0.05). Time of operative treatment of children with mild burns transferred from the two periods of time was close (Z=-0.417, P>0.05). Costs of operative treatment of children with moderate and severe burns transferred from January 2014 to December 2015 were significantly more than those of burn children transferred from January 2016 to September 2017 (Z=-3.324, t=2.167, P<0.05). Costs of operative treatment of children with mild and extremely severe burns transferred from the two periods of time were close (t=0.627, 0.808, P>0.05). (6)Time of non-operative treatment of children with mild, moderate, and severe burns transferred from January 2014 to December 2015 was obviously longer than that of burn children transferred from January 2016 to September 2017 (t=2.335, Z=-2.095, t=2.152, P<0.05). Time of non-operative treatment of children with extremely severe burns transferred from the two periods of time was close (t=0.450, P>0.05). Costs of non-operative treatment of children with moderate and severe burns transferred from January 2014 to December 2015 were obviously higher than those of burn children transferred from January 2016 to September 2017 (Z=-2.164, t=2.040, P<0.05). Costs of non-operative treatment of children with mild and extremely severe burns transferred from the two periods of time were close (t=0.146, 1.235, P>0.05). (7) Sixty-seven burn children transferred from January 2016 to September 2017 were transferred back to local hospitals for rehabilitation under the guidance of experts of the First Affiliated Hospital of Anhui Medical University, with 25 patients in 2016 and 42 patients in 2017. Effective rehabilitation rates of burn children transferred back to local hospitals for rehabilitation in 2016 and 2017 were both 100%. Conclusions The three-level collaboration network of pediatric burns treatment in Anhui province can effectively increase cure rate of children with mild, moderate, and severe burns, reduce incidence of shock of children with extremely severe burns, shorten time of operative treatment of burn children with moderate, severe, and extremely severe burns, and time of non-operative treatment of children with mild, moderate, and severe burns, reduce treatment costs of children with moderate and severe burns, and improve rehabilitation effectiveness of children transferred from Lu′an People′s Hospital and Fuyang People′s Hospital to the the First Affiliated Hospital of Anhui Medical University.

Objective:To explore the influence of parental compliance on the treatment of hypertrophic scars in burn children.Methods:A retrospective cohort study method was used. From June 2014 to June 2019, 49 children with post-burn hypertrophic scars who met the inclusion criteria and visited the outpatient department of the Department of Burns of the First Affiliated Hospital of Anhui Medical University were included in this study. In the follow-up of 9 months, according to the registration form and the results of the compliance questionnaire for parents, the children were divided into good compliance group (34 cases, 21 males and 13 females, aged 2.0 (2.0, 3.5) years) and poor compliance group (15 cases, 6 males and 9 females, aged 3.0 (2.0, 4.0) years). At the first attendance and in the follow-up of 3, 6, and 9 months, the scar scores of children in good compliance group were evaluated by Vancouver Scar Scale (VSS). At the first attendance and in the follow-up of 9 months, the scar scores of children in poor compliance group were evaluated by VSS. At the first attendance and in the follow-up of 9 months, the scar pruritus scores of children in the 2 groups were evaluated by Verbal Rating Score (VRS). Data was statistically analyzed with chi-square test, Wilcoxon rank sum test, Mann-Whitney U test, independent sample t test, and paired sample t test. Results:At the first attendance, the color, vascular distribution, softness, and thickness scores, and total score in VSS scoring of scars of children in the two groups were similar ( Z=0.834, 0.026, 0.837, 0.076, 1.074, P>0.05). In the follow-up of 9 months, the softness and thickness scores, and total score in VSS scoring of scars of children in good compliance group were significantly lower than those in poor compliance group ( Z=5.518, 4.732, 5.042, P<0.01). Compared with those in the first attendance, the color, vascular distribution, softness, and thickness scores, and total score in VSS scoring of scars of children in good compliance group were significantly decreased in the follow-up of 9 months ( Z=5.241, 5.273, 5.214, 5.245, 3.451, P<0.01); the color and vascular distribution scores, and total score in VSS scoring of scars of children in poor compliance group were significantly decreased in the follow-up of 9 months ( Z=3.606, 3.542, 3.448, P<0.01). At the first attendance, the VRS score of scar pruritus of children in good compliance group was 6.00 (5.00, 6.25) points, which was similar to (5.47±1.69) points in poor compliance group ( Z=0.607, P>0.05). In the follow-up of 9 months, the VRS score of scar pruritus of children in good compliance group was 1.00 (1.00, 1.25) points, which was significantly lower than (3.27±1.71) points in poor compliance group ( Z=2.606, P<0.01). Compared with those in the first attendance, the VRS score of scar pruritus of children in good compliance group was significantly decreased in the follow-up of 9 months ( Z=4.002, P<0.01), while there was no obvious change in poor compliance group in the follow-up of 9 months ( t=3.550, P>0.05). Conclusions:Under the same treatment plan, good parental compliance has a positive effect on the treatment of hypertrophic scars in burn children decreasing the degree of scar hyperplasia and pruritus.

OBJECTIVE To study the therapeutic effect of saikosaponins and paeoniflorin on rats with premenstrual dysphoric disorder(PMDD) model of liver Qi depression and the effect on neurotransmitters in hippocampal brain area. METHODS The PMDD rat model of liver Qi depression was prepared by the time-chosen chronic restraint stress method, and the depressive symptoms of rats were evaluated by the intervention of saikosaponins and paeoniflorin, the open field experiment and forced swimming experiment, and the changes of neurotransmitter levels in the hippocampal brain region of rats were detected by UHPLC-MS/MS target metabolomics. RESULTS The levels of 5-HT, Glu, GABA and NE in the hippocampal brain area of PMDD rats were significantly increased, and the levels of 5-HT, Glu, GABA, NE, DA and E were not statistically significant from those of the normal group after the intervention of saikosaponins and paeoniflorin. CONCLUSION Saikosaponins and paeoniflorin alleviates depression in rats with PMDD by regulating neurotransmitter levels, and it may be the pathway for the clinical treatment of PMDD with liver qi depression in the formulations of Bupleuri Radix and Paeoniae Radix Alba.
