Traditional Chinese medicine(TCM) is the pillar for the development of motherland medicine, and animal medicine has a long history of application in China, characterized by wide resources, strong activity, definite efficacy, and great benefits. It has significant potential and important status in the consumption market of raw materials of TCM. In the context of global climate change, farming system alterations, and low renewability, the depletion of wild medicinal animal resources has accelerated. Accordingly, the conservation and sustainable utilization of wild resources of animal medicinal materials has become a problem that garners increasing attention and urgently needs to be solved. This paper summarizes the current situation of domestic and foreign medicinal animal breeding and research progress in industrial application in recent years and points out the issues related to standardized breeding, germplasm selection and breeding, and quality evaluation standards for medicinal animals. Furthermore, this paper discusses standardized breeding, quality standards, resource protection and utilization, and the search for alternative resources for rare and endangered medicinal animals. It proposes that researchers should systematically carry out in-depth basic research on animal medicine, improve the breeding scale and level of medicinal animals, employ modern technology to enhance the quality standards of medicinal materials, and strengthen the research and development of alternative resources. This approach aims to effectively address the relationship between protection and utilization and make a significant contribution to the sustainable development of medicinal animal resources and the animal-based Chinese medicinal material industry.

The breakage pattern of unit particles during the production of oral solid dosage forms (OSD) is closely related to the quality of intermediate or final products. To accurately characterize the particles and study the evolution law of particle breakage, the Bonding model of the discrete element method (DEM) was used to investigate the breakage patterns of model parameters, particle shape and process conditions (loading mode and loading rate) on the dynamic breakage, force-time curve, breakage rate, maximum breakage size ratio and fracture strength of particles. The results showed that the particle breakage force was positively correlated with normal strength and bonded disk scale, negatively correlated with normal stiffness per unit area and tangential stiffness per unit area, and weakly correlated with tangential strength. The particle breakage rate was negatively correlated with the aspect ratio of the particles, and the maximum breakage size ratio was positively correlated with the aspect ratio of the particles; among the three loading modes, the breakage rate of compression breakage model was the largest, the breakage rate of shear breakage model was the second largest, and the breakage rate of wear breakage model was the smallest; the maximum breakage size ratio was positively correlated with the loading rate, the loading mode and the loading rate had no mutual influence on particle breakage rate, but had mutual influence on the maximum breakage size ratio. The research results will provide a theoretical basis for the shift of OSD from batch manufacturing to advanced manufacturing.

Objective To investigate the incidence rate,clinical characteristics,and prognosis of neonatal stroke in Shenzhen,China.Methods Led by Shenzhen Children's Hospital,the Shenzhen Neonatal Data Collaboration Network organized 21 institutions to collect 36 cases of neonatal stroke from January 2020 to December 2022.The incidence,clinical characteristics,treatment,and prognosis of neonatal stroke in Shenzhen were analyzed.Results The incidence rate of neonatal stroke in 21 hospitals from 2020 to 2022 was 1/15 137,1/6 060,and 1/7 704,respectively.Ischemic stroke accounted for 75％(27/36);boys accounted for 64％(23/36).Among the 36 neonates,31(86％)had disease onset within 3 days after birth,and 19(53％)had convulsion as the initial presentation.Cerebral MRI showed that 22 neonates(61％)had left cerebral infarction and 13(36％)had basal ganglia infarction.Magnetic resonance angiography was performed for 12 neonates,among whom 9(75％)had involvement of the middle cerebral artery.Electroencephalography was performed for 29 neonates,with sharp waves in 21 neonates(72％)and seizures in 10 neonates(34％).Symptomatic/supportive treatment varied across different hospitals.Neonatal Behavioral Neurological Assessment was performed for 12 neonates(33％,12/36),with a mean score of(32±4)points.The prognosis of 27 neonates was followed up to around 12 months of age,with 44％(12/27)of the neonates having a good prognosis.Conclusions Ischemic stroke is the main type of neonatal stroke,often with convulsions as the initial presentation,involvement of the middle cerebral artery,sharp waves on electroencephalography,and a relatively low neurodevelopment score.Symptomatic/supportive treatment is the main treatment method,and some neonates tend to have a poor prognosis.

Objective: To analyze and compare therapy responses, outcomes, and incidence of severe hematologic adverse events of flumatinib and imatinib in patients newly diagnosed with chronic phase chronic myeloid leukemia (CML) . Methods: Data of patients with chronic phase CML diagnosed between January 2006 and November 2022 from 76 centers, aged ≥18 years, and received initial flumatinib or imatinib therapy within 6 months after diagnosis in China were retrospectively interrogated. Propensity score matching (PSM) analysis was performed to reduce the bias of the initial TKI selection, and the therapy responses and outcomes of patients receiving initial flumatinib or imatinib therapy were compared. Results: A total of 4 833 adult patients with CML receiving initial imatinib (n=4 380) or flumatinib (n=453) therapy were included in the study. In the imatinib cohort, the median follow-up time was 54 [interquartile range (IQR), 31-85] months, and the 7-year cumulative incidences of CCyR, MMR, MR(4), and MR(4.5) were 95.2%, 88.4%, 78.3%, and 63.0%, respectively. The 7-year FFS, PFS, and OS rates were 71.8%, 93.0%, and 96.9%, respectively. With the median follow-up of 18 (IQR, 13-25) months in the flumatinib cohort, the 2-year cumulative incidences of CCyR, MMR, MR(4), and MR(4.5) were 95.4%, 86.5%, 58.4%, and 46.6%, respectively. The 2-year FFS, PFS, and OS rates were 80.1%, 95.0%, and 99.5%, respectively. The PSM analysis indicated that patients receiving initial flumatinib therapy had significantly higher cumulative incidences of CCyR, MMR, MR(4), and MR(4.5) and higher probabilities of FFS than those receiving the initial imatinib therapy (all P<0.001), whereas the PFS (P=0.230) and OS (P=0.268) were comparable between the two cohorts. The incidence of severe hematologic adverse events (grade≥Ⅲ) was comparable in the two cohorts. Conclusion: Patients receiving initial flumatinib therapy had higher cumulative incidences of therapy responses and higher probability of FFS than those receiving initial imatinib therapy, whereas the incidence of severe hematologic adverse events was comparable between the two cohorts.

Ecological agriculture is a crucial way for agriculture of Chinese materia medica, which emphasizes the application of ecological principles in the cultivation of traditional Chinese medicine. While long-term intensive farming and modern chemical agriculture have threatened soil health, the sustainable development of ecological agriculture of Chinese materia medica is constrained. No-til-lage can reduce both frequency and intensity of tillage. Compared with conventional agriculture, no-tillage can reduce soil disturbance, maintain no-tillage for a long or permanent period and keep mulching. The application of no-tillage has a long history. More and more studies have shown that no-tillage has many advantages over conventional tillage, and the ecological and economic benefits of no-tillage are particularly outstandingin long-term. The cultivation of Chinese medicinal materials adheres to the principle of not grabbing land from farmland, making full use of the soil resources under forests, mountains and wasteland. Reducing the risk of soil loss and sustai-nable utilization are the core issues in the process of new land cultivation. No-tillage application, which not only inherits the traditional Chinese concept of natural farming, but also integrates the laws of ecological agriculture, will become the core strategies of sustainable development of Chinese materia medica ecological agriculture. This study will introduce the basic concepts and development process of no-tillage, analyze their ecological benefits in ecological agriculture of Chinese materia medica, and put forward their application strategies.

Nitrogen is one of the most frequently used fertilizers in growth of Chinese medicinal plants(CMP). As in many other ecosystems, CMP ecosystem is also composed of plant-herbivore-natural enemy(tritrophic) interactions. Nitrogen fertilizer influences the growth and reproduction of CMP, and it is also able to heavily shape the ecosystem functions of CMP ecosystem through bottom-up forces. Understanding the specific effects of nitrogen fertilizer towards each trophic level will be beneficial to improve the resistance of CMP to herbivore and enhance the control efficiency of nature enemies to herbivore, and eventually, maximize the yield and quality of CMP. Most papers published on nitrogen use in plants focused mainly on the impact of nitrogen fertilization on CMP yield and quality. Influences of nitrogen application on CMP ecosystem get little attention at present. Therefore, this review summed up the potential effects of nitrogen fertilization on CMP ecosystem from perspectives of soil and tritrophic interactions. First of all, nitrogen fertilizer might decrease soil microbial biomass and altered the community structures of soil bacteria, fungi and protozoa. Negative effects of nitrogen fertilizer were found on biodiversity of soil bacteria and protozoa. Different fungi species respond differently to nitrogen fertili-zers. Nitrogen deposition can also decrease the soil pH. Decreases in soil microbial diversity and soil acidification can cause negative effects on CMP growth. In addition, nitrogen fertilizer could regulate the pest resistance of CMP including constitutive and inducible resistance. Both positive and negative effects of nitrogen application were found on pest resistance of CMP. Moreover, the development and predation of natural enemies were influenced by nitrogen deposition. Nitrogen influences natural enemies in many ways including plant volatiles, plant nutrient and structure and the supplementary food quality. Nectar and honeydew of plants and preys serve as important food source for natural enemies especially in early season when preys are still not available. Finally, the interactions between herbivores and their natural enemies were also shaped by nitrogen fertilizer in many aspects like increasing the nutritional content of prey and changing control efficiency of natural enemies. Some herbivores have evolved a strategy to sequester secondary metabolites which they absorbed from plant during their feeding. Studies showed that sequestration efficiency of secondary metabolites in prey could also be regulated by nitrogen. Parasitic, emergence, reproduction rate and longevity of parasites were found positively correlated with nitrogen deposition. Hopefully this study will shed light on practicable and economical application of nitrogen in cultivation of CMP.

Objective To analyze the overall functioning of children with learning disabilities, and develop individualized exercise rehabilitation protocol using International Classification of Functioning, Disability and Health (ICF). Methods Based on the theoretical framework of ICF and the disease diagnosis of International Classification of Diseases (ICD-11), and with the perspective of child development, the functional profiles of cognition, understanding, attention, thinking, motor, and activity and participation of children with learning disabilities were analyzed. A function-oriented and individulized exercise rehabilitation protocol for children with learning disabilities was constructed in light of ICF bio-psycho-social health paradignm and the theory of somatic and mental interaction. Results The functional performance of children with learning disabilities mainly demonstrated in mental dysfunction in physical functioning in the activities and participation limitations, such as learning and applying knowledge, general tasks and demands, and communication. For the environment factors, products and technology for education, products and technology for culture, recreation and sports, and services, systems and policies could also affect children with learning disabilities. Physical activity was beneficial for children with learning disabilities to improve mental and motor functioning and to effectively enhance intellectual, cognitive, attentional, communication, and mobility skills for the overall development of the children. Physical activity for children with learning disabilities was selected according to WHO guidelines for physical activity and sedentary behavior for children, and moderate to vigorous physical activity for at least 60 minutes, as well as high-intensity training no less than three times a week, together with appropriate physical games and leisure physical activities could effectively improve learning outcomes and reduce learning disabilities. Conclusion The health condition, functioning and motor development of children with learning disability had been analyzed using ICD-11 and ICF, and with the theories of somatic and metal interaction and ICF bio-psycho-social model, the holistic and function-oriented exercise rehabilitation program was developed that recommended at least 60 minutes of moderate intensity physical activity, including aerobic exercise and physical games, per day, and at least three times a week of high intensity physical activity of no less than 30 minutes, including plyometrics and physical competition. The development of individualized function-based exercise rehabilitation programs incorporating the learning disability and motor function characteristics of children could effectively improve the cognitive, attentional, and thinking functions of children with learning disabilities, reduce learning disabilities, and promote the overall development of children.

Rhizosphere bacteria play a vital role in plant nutrition absorption,growth and disease resistance. In this study,high-throughput sequencing technology was used to analyze the rhizosphere bacterial communities of Salvia miltiorrhiza and S. miltiorrhiza f. alba. Moreover,the function of dominant rhizosphere bacterial communities was analyzed. We found that Sphingobacteriales,Sphingomonadales and Nitrosomonadaceae were both dominant and specific bacteria in the rhizosphere of S. miltiorrhiza. The main functions of dominant rhizosphere bacteria communities in both species include promoting transformation of soil nutrients,improving plant immunity and ability of stress tolerance. This study was the first to compare rhizobacterial communities structure and function of S. miltiorrhiza and S. miltiorrhiza f. alba,which provided a new theoretical reference for studing the rhizosphere mechanism of healthy S. miltiorrhiza planting in the future.

Objective: To explore the effects of scar excision combined with negative-pressure on repair of hypertrophic scar in burn children. Methods: From October 2010 to August 2016, 25 children with hypertrophic scar after deep burn were hospitalized, with scar course ranging from 3 months to 11 years and scar area ranging from 35 to 427 [83(51, 98)]cm². A total of 35 scars of 25 children were located in trunk (11 scars), upper limb (11 scars), and lower limb (13 scars). All children received scar excision operation and negative-pressure treatment (negative-pressure value ranged from -40 to -20 kPa), among which 6 cases received scar excision operation and negative-pressure treatment for two times for further removal of scars. After scar excision, electronic spring scale was used to measure the tension of the incision. The tension value of children ranged from 3.43 to 23.84 [7.16 (5.59, 9.12)] N, and then the incision was closed with appropriate suture according to the value of the tension. The incision with smaller tension was firstly opened on post operation day (POD) 8. After removing the suture, negative-pressure was conducted to POD 14. The incision with larger tension was firstly opened on POD 12. After removing the suture, biological semi-membrane was used to reduce tension to POD 16. All healed incisions were performed with anti-scar treatment for 1 year and relaxation and fixation for 3 months. General condition of the incision was observed after operation. The reduction percentage of scar area was calculated half-year after operation. The Patient and Observer Scar Assessment Scale was used to record the overall score of scar and scar score of trunk, upper limb, and lower limb before operation and half-year after operation. Data were processed with paired t test and Wilcoxon rank sum test. Results: After removing the suture, all incisions of children healed well without redness, effusion, and rupture. Half-year after operation, the appearance and deformity of incision were obviously improved, and the symptoms including pruritus and pain were basically relieved. Half-year after operation, the scar area of children ranged from 0 to 174 [21(9, 47)]cm^2, which was significantly decreased as compared with that before operation (Z=-5.16, P<0.05). The reduction percentage of scar area ranged from 36% to 100% [(73±19)%]. Half-year after operation, the overall score of scar and scar score of trunk, upper limb, and lower limb of children were obviously decreased as compared with those before operation (with t values from 6.42 to 17.37, P values below 0.05). Conclusions Scar excision combined with negative-pressure treatment has a good clinical effect on repair of hypertrophic scar in burn children, which is suitable for clinical application.
