The development and application of processing technology is closely related to the quality of Chinese medicine. Currently, Chinese medicine processing is still in the mechanization stage with limited processing equipment, low levels of automation and intelligence. As a result, the imprecise control of parameters during processing leads to unstable quality of Chinese herbal pieces. However, with the arrival of the big data era and the continuous development of "Internet+", Chinese medicine processing technology and equipment have been continuously improved and updated, and gradually shifted to the development direction of automation and intelligence. The linkage production technology of Chinese herbal pieces optimizes the separate processing equipment coupling into the production line for continuous manufacture of Chinese herbal pieces, intending to improve production efficiency. The large-scale industrialized production of Chinese herbal pieces tends towards digital technology of processing experience and online inspection technology based on machine vision, electronic nose, and electronic tongue. These technologies are crucial prerequisites for standardizing the parameters of Chinese medicine processing. And further by docking the processing process and equipment with the internet, realizing the intelligent control of the production process is an important process for the transformation and upgrading of Chinese herbal piece industry in the future. In this paper, we summarized the development characteristics of different stages of Chinese medicine processing technology, combed application and development of processing theory, the evolution of processing equipment, and problems in the current industrial development stage of Chinese medicine processing, in order to provide ideas and methods for achieving digital and intelligent innovation of processing technology as well as high-efficient and high-quality production of Chinese herbal pieces.

Abstract: Objective To investigate the clinical types of children's tinea capitis and the distribution of fungal pathogens in Wuhan from 2011 to 2020, and to provide scientific basis for the prevention, diagnosis and treatment of children's tinea capitis. Methods Laboratory data of children with tinea capitis in outpatient and inpatient department of dermatology in Wuhan No.1 Hospital from January 2011 to December 2020 were collected. A total of 542 cases of pediatric tinea capitis were included, with 239 male cases and 303 female cases. Microscopic examination of fungi and culture identification were performed on the affected skin lesions of the children. Chi-square test was used to analyze the differences in pathogen spectrum of children with different age groups and clinical type. Results Among the pediatric tinea capitis patients, the age group with the highest prevalence was preschool children(3 to <7 years old), accounting for 48.52%(263/542). The top three pathogenic fungi were Trichophytes violaceum(49.26%, 267/542), Microsporum canis(31.55%, 171/542) and Trichophyton mentagrophytes (9.96%, 54/542). Trichophyton violaceum was the main pathogen in all ages, followed by Microsporum canis. The infection rate of Microsporum canis in children over 7 years old was lower than that in children under 7 years old, and the infection rate of Trichophyton rubrum in infants was higher than that in other ages. The distribution of Trichophytes violaceum, Trichophyton mentagrophytes, Nannizzia gypseum and Microsporum ferrugineum was uniform in all age groups. Trichophytes violaceum and Trichophyton tousurans mainly caused black-dot ringworm, Microsporum canis mainly caused tinea alba, Trichophyton mentagrophytes,Nannizzia gypseum and Trichophytonrubrum mainly caused kerion. Except for Microsporum ferrugineum, the composition ratios of other fungi species showed statistically significant differences among different clinical types of tinea capitis(P<0.05). Conclusions Preschool children are the most commonly affected age group by pediatric tinea capitis, and black-dot ringworm caused by Trichophytes violaceum is the main clinical type. Analysis of the high-riskage group, pathogenic fungi and clinical types of tinea capitis in children can enhance the understanding of its epidemiological characteristics, which is helpful for early diagnosis and targeted standardized treatment of pediatric tinea capitis.

Objective:To explore the different coagulation state in patients with adenomyosis and its clinical significance.Methods:Clinical data of the patients admitted to the First Affiliated Hospital of Nanjing Medical University from January 2017 to December 2021 were retrospectively analyzed. (1) Differential coagulation state between 25 healthy women and 25 patients with adenomyosis were compared during menstrual and non-menstrual periods. (2) The coagulation indexes of 145 patients with adenomyosis (observation group 1) and 129 patients with cervical intraepithelial neoplasia grade Ⅲ (control group 1) who underwent hysterectomy in non-menstrual period were compared. (3) The coagulation indexes of 154 patients with adenomyosis (observation group 2) and 147 women without myometrial lesions (control group 2) who underwent endometrial curettage during uterine bleeding period were compared. (4) Correlations of coagulation index with cancer antigen 125 (CA 125), cancer antigen 19-9 (CA 19-9) and uterine volume in patients with adenomyosis were analyzed. Results:(1) The coagulation state of each health women during the menstrual and non-menstrual period showed no significant differences (all P>0.05). For the 25 patients with adenomyosis, fibrinogen [FIB; 2.61 g/L(2.50-3.10 g/L)] and D-dimer [0.60 mg/L (0.40-1.00 mg/L)] in the menstrual period were significantly higher than those in the non-menstrual period [2.25 g/L (1.90-2.70 g/L) and 0.27 mg/L (0.20-0.40 mg/L), respectively; both P<0.01], while thrombin time [TT; 16.70 s (16.10-17.40 s)] in the menstrual period was significantly lower than that in the non-menstrual period [17.95 s (17.20-18.40 s); P<0.01]. (2) In the non-bleeding period, D-dimer [0.26 mg/L (0.20-0.40 mg/L)] and platelet count [257.0×10 9/L (212.0×10 9/L-308.5×10 9/L)] of observation group 1 were significantly higher than those of control group 1 (all P<0.01). Besides, FIB ( r=0.237, P=0.004) and D-dimer ( r=0.373, P<0.001) were positively correlated with CA 125, while prothrombin time (PT; r=-0.208, P=0.012) and internationalized normalized ratio of plasma prothrombin time (PT-INR; r=-0.201, P=0.015) were negatively correlated with CA 19-9. (3) In the bleeding period, PT [10.70 s (10.10-11.20 s)] and PT-INR [0.93 (0.90-1.00)] of observation group 2 were significantly lower than those of control group 2 (all P<0.01), while D-dimer [0.41 mg/L (0.20-0.80 mg/L)] was significantly higher than that in the control group 2 ( P<0.001). Furthermore, FIB ( r=0.252, P=0.038) and D-dimer ( r=0.321, P=0.008) were positively correlated with uterine volume, while activated partial thromboplastin time (APTT; r=-0.190, P=0.018) and TT ( r=-0.304, P=0.012) were negatively correlated with uterine volume. (4) During non-menstrual period and uterine bleeding period, APTT and TT in patients of observation group 1 and 2 combined with anemia were significantly lower than those of non-anemia patients (all P<0.05). Conclusion:Patients with adenomyosis have a tendency to hypercoagulability in both the uterine bleeding and non-bleeding periods, which may be related to enlarged uterine volume, increased serum CA 125 and anemia.

Objective:To assess impact of radiation from nuclear power on the surrounding environment, a dose assessment model was constructed and relevant dose coefficients were determined through refined animal models.Methods:Zebrafish is one of the most important aquatic model animals in the radiation hazard assessment of nuclear power liquid effluent. A geometric model of zebrafish containing internal bones and visceral organ was established for dose estimation. The internal and external dose coefficients (DC) of the zebrafish model were calculated by Monte Carlo method with seven nuclides as the source term, 3H, 40K, 58Co, 60Co, 110Ag, 134Cs, 137Cs, which are common in nuclear liquid effluents and environmental monitoring. Results:The level of nuclide gamma energy determines dose coefficients for external radiation. The dose coefficients of most nuclides in internal organs was higher than that in whole body, and the internal organ dose of 58Co was 165% higher than that in whole body. The internal radiation dose coefficients of the model established in this study was relatively high, and the internal radiation dose coefficients caused by 60Co was 2.6 times of existing ellipsoid model, which suggested that the different internal materials and the choice of different particle types would affect the energy deposition. Conclusions:Refining of model animals is important. Accurate assessment of the organs dose coefficients of model animals is helpful to assess the radiation effects on non-human species.

Objective:
To understand the prevalence and influencing factors of children with ASD in central and eastern Inner Mongolia, and to provide theoretical basis for disease prevention and prevalence of ASD.
Methods:
Sixteen primary schools and kindergartens were selected from 5 cities in central and eastern Inner Mongolia through random cluster sampling. A total of 15 817 children aged 3-14 years were selected. Children who were positive using Clancy Autism Behavior Scale were further diagnosed according to the teacher s nomination form and the Autism Behavior Checklist, as well as the diagnostic criteria of the fifth edition of the American Diagnostic & Statistical Manual of Mental Disorders by 2 professionals.
Results:
The prevalence of ASD was 0.27% (42/15 817), with prevalence in urban areas (0.16%, 15/9 231) higher than that of rural areas (0.41%, 27/6 586) ( χ 2=8.89, P <0.01). Logistic regression analysis showed that maternal education and language development were negatively associated with ASD in urban children [ OR =0.29(95% CI =0.12-0.69) and 0.18(95% CI =0.05-0.60), P <0.05]. ASD in rural children were positively associated with enuresis and introverted family members [ OR =7.09(95% CI =1.60-32.27) and 8.63(95% CI =3.10- 24.01 ), P <0.05].
Conclusion
High prevalence of ASD is found in urban area of central and eastern Inner Mongolia. Unhealthy habits, neonatal diseases, low parental education, delayed language development and poor exercise performance are primary factors associated with ASD in both urban and rural areas.
