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.

Objective:
To explore the ideal sagittal position of the lower third of the face in high-angle patients with different forehead forms and to provide a reference for clinical treatment.
Methods:
Informed consent and portrait authorization were obtained from all patients, and the study passed the ethical review of the unit. We categorized forehead forms into four types: straight, rounded, type I angular (angled at the middle third of the forehead) and type II angular (angled at the upper third of the forehead). Profiles of high-angle patients with different forehead forms were collected. The initial position was when the facial axis point (FA point) was positioned at the goal anterior-limit line (GALL). After being silhouetted, the lower third of the face was moved forward and backward by 1 mm, 2 mm, 3 mm, and 4 mm each, plus the initial silhouetted picture, to obtain 9 images for each patient. A survey was created with these lateral profile silhouettes, and the silhouette images were ranked by 30 orthodontists and 30 laypersons.
Results:
There were significant differences in profile scores at different movement distances of the lower third of the face among high-angle patients with different forehead shapes (P<0.05). Overall, high-angle patients with straight or type II angular foreheads had higher scores when the lower third of the face did not move. For high-angle patients with a rounded forehead, orthodontists and laypersons gave the highest scores when the lower third of the face was moved backward by 2 mm and 4 mm, respectively. For high-angle patients with a type I angular forehead, orthodontists thought the scores of backward movement of 4 mm were the highest, and laypersons thought the scores of backward movement of 3 mm were the highest. No significant difference was found in scores between orthodontists and laypersons (P>0.05).
Conclusion
The forehead forms and the sagittal position of the lower third of the face will affect the face’s profile aesthetics. Patients with straight and type Ⅱ angular foreheads has the best profile when the FA point is located on the GALL line. For patients with rounded and type Ⅰ angular foreheads, a posterior location of the lower third of the face is more desirable than the initial position.

Objective:To observe and analyze the structural characteristics of the optic discs in high myopia (HM) combined with primary open-angle glaucoma (POAG) and the optic disc parameters with diagnostic efficacy.Methods:A cross-sectional study. From August 2020 to March 2021, a total of 114 eyes of 68 patients with POAG, HM and healthy volunteers who were diagnosed by Department of Ophthalmology, The First Affiliated Hospital of Kunming Medical University were included in the study. Among them, 21 POAG patients (39 eyes) were divided into H+P group (9 patients, 18 eyes) and non-H+P group (12 patients, 21 eyes) according to whether or not HM was combined; 26 HM patients (37 eyes) were selected as HM group; 21 healthy volunteers (38 eyes) were selected as normal control group. The subjects included 31 males (51 eyes) and 37 females (63 eyes), whose average age was 36.93±12.60 years old. Diopter, central corneal thickness (CCT) and axial length (AL) were measured. There was no significant difference in age ( F=8.333), sex composition ratio ( χ2=0.863), and CCT ( F=1.425) among the four groups ( P>0.05); while, there were significant differences in AL ( F=69.956), diopter ( F=37.711), visual field index (VFI) ( F=43.254) and mean defect (MD) ( F=49.793) among the four groups ( P<0.01). Enhanced depth imaging using optical coherence tomography was used to obtain the tilt parameters, the disc rim parameters, the lamina cribrosa parameters and the retinal nerve fiber layer (RNFL) thickness. The tilt parameters included optic disc horizontal diameter, optic disc vertical diameter, optic disc ellipse index (horizontal diameter/vertical diameter); the disc rim parameters included Bruch’s membrane opening-minimal rim width (BMO), optic cup area, optic disc area, disc rim area, cup-disc area ratio; the lamina cribrosa parameters included anterior laminar insertion depth (ALID), prelaminar neural tissue (PLNT), and lamina cribrosa thickness. The pairwise comparison between groups were performed by ANOVA test. Pearson correlation analysis was used to analyze the correlation between disc tilt parameters, disc rim parameters, lamina cribrosa parameters and visual field parameters, as well as between disc rim parameters and RNFL thickness. According to receiver operating characteristic (ROC) curve and area under the curve (AUC), the predictive value of those above related factors for HM combined with POAG was evaluated. Results:Tilt parameters: compared with the optic disc horizontal diameter of non-H+P group, those of normal control group, HM group and H+P group were significantly decreased ( P<0.05), the ellipse indices of HM group and H+P group were significantly lower than those of normal control group and non-H+P group ( P<0.05). The results of correlation analysis showed that the optic disc horizontal and vertical diameters were negatively correlated with MD ( r=-0.302,-0.235; P=0.002, 0.017), and negatively correlated with VFI ( r=-0.291,-0.246; P=0.003, 0.013). Disc rim parameters: the disc cup area and cup-disc area ratio of non-H+P group and H+P group were significantly larger than those of normal control group and HM group ( P<0.05). The disc rim area and the average BMO of HM group, non-H+P group and H+P group were significantly smaller than those of normal control group ( P<0.05). The results of correlation analysis showed that the cup-disc area ratio ( r=-0.584), the average BMO ( r=0.650) had the highest correlation with the average RNFL thickness ( P<0.001). The superior, inferior, nasal and temporal BMO were all positively correlated with the corresponding quadrant RNFL thicknesses ( r=0.431, 0.656, 0.362, 0.375; P<0.05); the optic disc rim area, the average BMO were positively correlated with MD ( r=0.449, 0.618) and VFI ( r=0.449, 0.605) ( P<0.05), among which the correlation of the average BMO was the highest; the optic cup area and cup-disc area ratio were negatively correlated with MD ( r=-0.346,-0.559) and VFI ( r=-0.312,-0.548) ( P<0.001), among which the correlation of the cup-disc area ratio was the highest. Lamina cribrosa parameters: ALID of non-H+P group and H+P group were significantly deeper than those of normal control group and HM group ( P<0.05). LC of non-H+P group and H+P group were significantly thinner than those of normal control group and HM group ( P<0.05). The results of correlation analysis showed that ALID was negatively correlated with MD and VFI ( r=-0.402, P<0.001), VFI ( r=-0.405, P=0.001); LC was positively correlated with MD and VFI ( r=0.403, P<0.001), VFI ( r=-0.401, P=0.015). Comparison of diagnostic efficiency between various optic disc parameters: the results of ROC analysis showed that the cup-disc area ratio had the highest diagnostic performance (AUC=0.847, P=0.007), the maximum Youden index was 0.563, the sensitivity and specificity were 0.833 and 0.730, respectively, and the best critical value was 0.340. Conclusions:Optic disc tilt is more pronounced in HM combined with POAG; BMO in each quadrant could objectively reflect the disc rim defect of HM combined with POAG; the thinning and the backward shift of the lamina cribrosa were consistent with the aggravation of the visual field defect. Among them, the cup-disc area ratio had better diagnostic performance.

Seed quality plays an important role in the agricultural and animal husbandry production, the effective utilization of genetic resources, the conservation of biodiversity and the restoration and reconstruction of plant communities. Seed aging is a common physiological phenomenon during storage. It is a natural irreversible process that occurs and develops along with the extension of seed storage time. It is not only related to the growth, yield and quality of seed and seedling establishment, but also has an important effect on the conservation, utilization and development of plant germplasm resources. The physiological mechanisms of seed aging are complex and diverse. Most studies focus on conventional physiological characterization, while systematic and comprehensive in-depth studies are lacking. Here we review the recent advances in understanding the physiology of seed aging process, including the methods of seed aging, the effect of aging on seed germination, and the physiological and molecular mechanisms of seed aging. The change of multiple physiological parameters, including seed vigor, electrical conductivity, malondialdehyde content and storage material in the seed, antioxidant enzyme activity and mitochondrial structure, were summarized. Moreover, insights into the mechanism of seed aging from the aspects of transcriptome, proteome and aging related gene function were summarized. This study may facilitate the research of seed biology and the conservation and utilization of germplasm resources.

Objective:To investigate the efficacy and safety of radiotherapy for all metastases in patients with metachronous oligo-metastatic prostate cancer after radical treatment.Methods:From October 2011 to February 2021, 41 patients with prostate cancer with less than 5 metastases after radical treatment were retrospectively analyzed in a single center. The median age at radiotherapy was 68 (57-81) years. Forty patients (98%) received androgen deprivation therapy (ADT). There were 28 patients in the hormone sensitive (HSPC) group and 13 patients in the hormone resistant (CRPC) group. The median initial PSA was 24.4 (7.4-399.0) ng/ml. Tumor stage: T 2 stage 11 patients, T 3 stage 27 patients, T 4 stage 3 patients.30 patients were in N 0 stage and 11 patients in N 1 stage. Gleason score was 7 in 12 patients, 8 in 9 patients, 9 in 18 patients, and 10 in 2 patients.33 patients were treated with surgery, and 8 patients were treated with radiotherapy. The time span from diagnosis to metastasis was 3.1 (0.2-1.8) years. Conventional imaging examination (CT/ MRI/bone scan) before radiotherapy was used in 7 patients, and PSMA PET/CT examination was used in 34 patients.The median PSA before radiotherapy was 1.3(0.1-33.8) ng/ml. There were 62 metastases in 41 patients, including 1 lesion in 28 patients, 2 lesions in 9 patients, 3 lesions in 2 patients, and 5 lesions in 2 patients. Fifty-four patients had bone metastases and eight had retroperitoneal lymph node metastases. Twenty-two bone metastases were located in the pelvis, 18 in the vertebral body, 12 in the ribs, one in the femur and one in the sternum.The median metastatic volume was 5.8(0.2-81.7) cm 3.Daily image-guided rotational intensity modulated radiotherapy was used to cover all metastases.Dose segmentation modes include 37.5Gy/7.5Gy/5F, 60Gy/3Gy/20F, 65-70Gy/2.6-2.8Gy/25F.The median biological effective dose (BED 3) was 120 (67-147) Gy. The primary endpoint was biochemical progression-free survival (BPFS), the secondary endpoints were acute and late toxic side effects, local relapse-free survival (LPFS), and overall survival (OS). Results:The median follow-up time was 21 months (range 5-72 months). All patients completed radiotherapy, and 16 patients had grade 1 to 2 acute toxicity and side effects, and no grade 3 or above acute and late stage side effects. 1-year LPFS was 97.1%.The 1-year and 2-year BPFS were 77.5% and 59.2%, respectively. The median BPFS time was 29 months (range 13.9-44.2 months). Univariate analysis showed that the HSPC group ( P<0.001) and the group with total metastatic volume ≤ 5.8cm 3 ( P=0.010) had higher BPFS. The median BPFS time was 37 months in the retroperitoneal lymph node metastases subgroup and 17 months in the bone metastases subgroup ( P=0.141). In the HSPC group, the median BPFS was 30(22-38) months. After radiotherapy, PSA decreased in all 28 patients, and increased in 6 patients. The median BPFS was 12(4-18) months. In the CRPC group, the median BPFS was 4(0-8) months. PSA decreased in 10 patients (76.9%) after radiotherapy, and PSA decreased in 6 patients. The median BPFS was 5(3-28) months. Three patients’PSA did not decrease after radiotherapy, and they were treated with new endocrine therapy drugs, chemotherapy, immunotherapy and other systemic therapy. Conclusions:For patients with metachronous metastases after radical treatment, full coverage radiotherapy has good safety and high local control rate. HSPC patients and patients with low tumor load could be recommended to receive radiotherapy for all metastatic lesions preferentially, and patients with only retroperitoneal lymph node metastases may have better prognosis after radiotherapy than patients with bone metastases.

Objective:To develop and validate a nomogram for predicting the 1-and 3-year survival rates of patients receiving peritoneal dialysis.Methods:Patients who underwent peritoneal dialysis for the first time in Zhujiang hospital from January 1, 2010 to December 31, 2017 were enrolled. The patients from January 1, 2014 to December 31, 2017 were enrolled in a training dataset. Baseline clinical data were collected and the primary endpoint was all-cause death. Cox proportional hazard regression models were used to analyze risk factors affecting the survival rates. Nomograms were generated using the R rms package. The Harrell' concordance index (C-index), receiver operating characteristic curve and calibration curve were used to verify the performance of the model. Patients who underwent peritoneal dialysis from January 1, 2010 to December 31, 2013 were then selected to validate the external predictive accuracy of the prediction models.Results:The prediction cohort enrolled 457 patients, with a median follow-up time of 27.67(18.37, 39.22) months, and 64 patients (14.00%) died during follow-up. The 1-and 3-year cumulative survival rates were 96.4% and 83.0%. Multivariate analysis showed that aging (every 1 year old increase, HR=1.07, 95% CI 1.04-1.09, P<0.001), stroke ( HR=3.63, 95% CI 1.93-6.85, P<0.001), higher cholesterol (every 1 mmol/L increase, HR=1.51, 95% CI 1.20-1.89, P<0.001), higher neutrophil-to-lymphocyte ratio (every 1 increase, HR=1.12, 95% CI 1.05-1.20, P=0.001), and lower albumin ( HR=0.89, 95% CI 0.82-0.95, P=0.001) were independent risk factors affecting the survival rates of PD patients. The C-index of the prediction cohort and the validation cohort were 0.815(95% CI 0.765-0.865) and 0.804(95% CI 0.744-0.864, respectively). Both internally and externally verified calibration curves showed that the predicted results were close to the actual survival rates. Conclusion:Based on age, blood total cholesterol level, stroke history, and NLR, the prognosis prediction model of peritoneal dialysis patients established with nomogram can help predict the 1-year and 3-year survival rates of peritoneal dialysis patients.
