[Expert consensus on the application of critical care ultrasonography in invasive procedures].

The evolution of critical care medicine is inextricably linked to the development of critical care procedures. These procedures not only facilitate diagnosis and treatment of critically ill patients, but also provide valuable insights into disease pathophysiology. While critical care interventions offer undeniable benefits, the potential for iatrogenic complications necessitates careful consideration. The recent surge in critical care ultrasound (US) utilization is a testament to its unique advantages: non-invasiveness, real-time bedside availability, direct visualization of internal structures, elimination of ionizing radiation exposure, repeatability, and relative ease of learning. Recognizing the need to optimize procedures and minimize complications, critical care utrasound study group of Beijing critical care ultrasound research assocition convened a panel of critical care experts to generate this consensus statement. This document serves as a guide for healthcare providers, aiming to ensure patient safety and best practices in critical care.

Effectiveness of Pamidronate Infusion in the Treatment of Charcot Arthropathy.

Introduction: The objective of this case series is to investigate the efficacy and safety of intravenous infusion of Pamidronate, a second generation bisphosphonate, in the treatment of active Charcot arthropathy. Materials and methods: All patients with active Charcot arthropathy treated at the medical centre from 1 January 2013 to 30 June 2020 were included in the study. Efficacy outcome was evaluated based on time to consolidate findings observed through radiographic examination, while safety outcome was evaluated based on the incidence of adverse event (AE) occurrence. Results: A total of 81 patients (37 male, 44 female) diagnosed with active Charcot arthropathy were included. 64.2% of patients were at stage 1 of Charcot arthropathy whereas 35.8% were at stage 2. The mean time to consolidate for stage 1 and stage 2 was 6.50 ± 4.21 months and 3.63 ± 2.92 months respectively (p-value = 0.139). No significant association was observed between gender, ethnicity and disease stage with the consolidation time (p-value >0.05). The rate of AE incidence was 2.5%, observed in 2 patients who developed a fever during the treatment. No other serious AE was observed in the study. Conclusion: Intravenous Pamidronate infusion is a safe and effective treatment option for Charcot arthropathy.

Intravoxel incoherent motion diffusion-weighted imaging of solitary pulmonary lesions: initial study with gradient- and spin-echo sequences.

AIM: To evaluate the feasibility and image quality of intravoxel incoherent motion diffusion-weighted imaging (IVIM) using gradient- and spin-echo (GRASE) in solitary pulmonary lesions (SPLs) compared to echo planar imaging (EPI) and turbo spin-echo (TSE) at 3 T. MATERIALS AND METHODS: Forty-two patients with SPLs underwent lung magnetic resonance imaging (MRI) using TSE-IVIM, GRASE-IVIM, and EPI-IVIM at 3 T. Signal ratio (SR), contrast ratio (CR), and image distortion ratio (DR) of three sequences were compared. The reproducibility and repeatability of the apparent diffusion coefficient (ADC) and IVIM-derived parameters were assessed using the interclass correlation coefficient (ICC) and coefficient of variation (CV). The repeatability of the ADC and IVIM-derived parameters between all sequences was evaluated using the Bland-Altman method. RESULTS: EPI-IVIM had a higher SR, lower CR, and higher DR (p<0.05); however, there was no significant difference between TSE-IVIM and GRASE-IVIM (p>0.05). Compared to the D and f values of TSE-IVIM (ICC lower limit >0.90), GRASE-IVIM and EPI-IVIM showed poor reproducibility (ICC lower limit<0.90). The repeatability of the ADC and D values obtained by TSE-IVIM (CV, 1.93-2.96% and 2.44-3.18%, respectively) and GRASE-IVIM (CV, 2.56-3.12% and 3.21-3.51%, respectively) were superior to those of EPI-IVIM (CV, 10.03-10.2% and 11.30-11.57%). The repeatability of D∗ and f values for all sequences was poor. Bland-Altman analysis showed wide limits of agreement between the ADC and IVIM-derived parameters for all sequences. CONCLUSION: GRASE-IVIM reduced the DR, improved the stability of the ADC and D values on repeated scans, and had the shortest scanning time.

The first intron of EIJ1 confers a specific response to wounding and herbivore stresses.

Plants are constantly exposed to different kinds of biotic stress, such as herbivore attack and wounding. To deal with these stresses, plants have evolved sophisticated defence mechanisms to protect themselves. Previously, we found that EIJ1 (EDS1-interacting J protein 1) plays a negative regulatory role in plant disease resistance in Arabidopsis thaliana. Follow-up studies revealed that EIJ1 specifically responds to wounding and herbivore stresses. The expression of EIJ1 was specifically induced by wounding or herbivore stress, as demonstrated by similar results in EIJ1 protein assay. Interestingly, GUS staining found that the promoter of EIJ1 is not involved in the induction of expression under wounding stress. Instead, we identified the first intron of EIJ1 as a key factor in response to wounding stress. Deleting the first intron of EIJ1 resulted in a loss of response to wounding stress in plants. Our results broaden the role of EIJ1 in plant resistance to biotic stress and provide new insights into plant responses to biotic stress.

[Analysis and treatment workflow of modified seven-step approach for acute respiratory and circulatory disorders].

Acute respiratory and circulatory disorders are the most common critical syndromes, the essence of which is damage to the organs/systems of the heart and lungs. These comprise the essential manifestation of disease and injury progression to the severe stage. Its development involves the following components: individual specificity, primary disease strike, dysregulation of the host's response, and systemic disorders. Admission for acute respiratory and circulatory disorders is a clinical challenge. Based on a previously proposed flow, a critical care ultrasound-based stepwise approach (PIEPEAR) as a standard procedure to manage patients with acute cardiorespiratory compromise and practical experience in recent years, a modified seven-step analysis and treatment process has been developed to help guide clinicians with rational thinking and standardized treatment when faced with acute respiratory and circulatory disorders. The process consists of seven steps: problem-based clinical analysis, intentional information acquisition, evaluation of core disorder based on critical care ultrasound, pathophysiology and host response phenotype identification, etiology diagnosis, act treatment through pathophysiology-host response and etiology, and re-check. The modified seven-step approach is guided by a "modular analysis" style of thinking and visual monitoring. This approach can strengthen the identification of clinical problems and facilitate a three-in-one analysis. It focuses on pathophysiological disorders, body reactions, and primary causes to more accurately understand the condition's key points, and make treatment more straight forward, to finally achieve the aim of "comprehensive cognition and refined treatment".

[Human amniotic membrane plug for recurrent retinal detachment associated with pathologic myopic macular hole].

A 60-year-old woman presented with a history of "pathological myopia combined with macular hole retinal detachment, " for which she underwent vitrectomy, internal limiting membrane tamponade, and silicone oil filling surgery one year ago. Seven months ago, the silicone oil was removed. She now returned to seek medical attention as her visual acuity has declined by 10 diopters. Examination revealed a recurrence of macular hole retinal detachment. The patient was treated with combined amniotic membrane tamponade and silicone oil filling. During the surgery, the frozen amniotic membrane was cut into 2 mm × 2 mm and placed under the macular hole retina after silicone oil filling. Within 6 months after the surgery, her retina repositioned well, the macular hole closed, and her visual function improved from hand motion to 0.05. No severe complications were observed. Therefore, this surgical approach provides a new perspective for treating recurrent pathological myopia combined with macular hole retinal detachment.

Diagnosis of spinal dural arteriovenous fistula: a multimodal MRI assessment strategy.

AIM: To identify more specific screening indicators at magnetic resonance imaging (MRI) for the diagnosis of spinal dural arteriovenous fistulas (SDAVFs) and to determine an efficient diagnostic strategy. MATERIALS AND METHODS: This retrospective study analysed clinical and imaging data of patients diagnosed with SDAVF and alternative myelopathy who underwent conventional MRI examinations. Additionally, three-dimensional (3D) T2-weighted sampling perfection with application-optimised contrasts using different flip-angle evolutions (3D-T2-SPACE) and contrast-enhanced magnetic resonance angiography (CE-MRA) data from patients with SDAVF were compared with digital subtraction angiography (DSA) data. RESULTS: The age of onset, perimedullary flow voids (PFV), distribution of lesions, syringomyelia, degree of spinal oedema, and cauda equina disorder (CED) were factors that showed statistically significance in the identification of SDAVF with alternative myelopathy. After controlling for age, gender, PFV, degree of spinal cord swelling, and syringomyelia, the multivariable ordinal logistic regression model showed that the CED sign (OR = 32.46; 95% confidence interval [CI]: 2.47-427.15; p=0.008) was an independent predictor for SDAVF. The diagnostic model constructed using the PFV and CED signs had better diagnostic performance, with an area under the curve of 0.957 (p<0.001), maximum Youden index of 0.844, sensitivity of 92.9%, and specificity of 91.5%. Both 3D-T2-SPACE (77.8%) and CE-MRA (83.3%) sequences had good localisation values for SDAVF. Combining the two imaging examinations had better diagnostic accuracy than that of DSA. CONCLUSION: CED and PFV on conventional MRI were specific indicators for the diagnosis of SDAVF. To compensate for the lack of fistula localisation on conventional MRI, 3D-T2-SPACE and CE-MRA can be used. Together they complement each other and have good diagnostic potential.

[Based on CT radiomics model for predicting the response to first-line chemotherapy of diffuse large B-cell lymphoma].

Objective: To investigate the potential value of CT Radiomics model in predicting the response to first-line chemotherapy in diffuse large B-cell lymphoma (DLBCL). Methods: Pre-treatment CT images and clinical data of DLBCL patients treated at Shanxi Cancer Hospital from January 2013 to May 2018 were retrospectively analyzed and divided into refractory patients (73 cases) and non-refractory patients (57 cases) according to the Lugano 2014 efficacy evaluation criteria. The least absolute shrinkage and selection operator (LASSO) regression algorithm, univariate and multivariate logistic regression analyses were used to screen out clinical factors and CT radiomics features associated with efficacy response, followed by radiomics model and nomogram model. Receiver operating characteristic (ROC) curve, calibration curve and clinical decision curve were used to evaluate the models in terms of the diagnostic efficacy, calibration and clinical value in predicting chemotherapy response. Results: Based on pre-chemotherapy CT images, 850 CT texture features were extracted from each patient, and 6 features highly correlated with the first-line chemotherapy effect of DLBCL were selected, including 1 first order feature, 1 gray level co-occurence matrix, 3 grey level dependence matrix, 1 neighboring grey tone difference matrix. Then, the corresponding radiomics model was established, whose ROC curves showed AUC values of 0.82 (95% CI: 0.76-0.89) and 0.73 (95% CI: 0.60-0.86) in the training and validation groups, respectively. The nomogram model, built by combining validated clinical factors (Ann Arbor stage, serum LDH level) and CT radiomics features, showed an AUC of 0.95 (95% CI: 0.90-0.99) and 0.91 (95% CI: 0.82-1.00) in the training group and the validation group, respectively, with significantly better diagnostic efficacy than that of the radiomics model. In addition, the calibration curve and clinical decision curve showed that the nomogram model had good consistency and high clinical value in the assessment of DLBCL efficacy. Conclusion: The nomogram model based on clinical factors and radiomics features shows potential clinical value in predicting the response to first-line chemotherapy of DLBCL patients.

[Expert consensus on late stage of critical care management].

We wished to establish an expert consensus on late stage of critical care (CC) management. The panel comprised 13 experts in CC medicine. Each statement was assessed based on the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) principle. Then, the Delphi method was adopted by 17 experts to reassess the following 28 statements. (1) ESCAPE has evolved from a strategy of delirium management to a strategy of late stage of CC management. (2) The new version of ESCAPE is a strategy for optimizing treatment and comprehensive care of critically ill patients (CIPs) after the rescue period, including early mobilization, early rehabilitation, nutritional support, sleep management, mental assessment, cognitive-function training, emotional support, and optimizing sedation and analgesia. (3) Disease assessment to determine the starting point of early mobilization, early rehabilitation, and early enteral nutrition. (4) Early mobilization has synergistic effects upon the recovery of organ function. (5) Early functional exercise and rehabilitation are important means to promote CIP recovery, and gives them a sense of future prospects. (6) Timely start of enteral nutrition is conducive to early mobilization and early rehabilitation. (7) The spontaneous breathing test should be started as soon as possible, and a weaning plan should be selected step-by-step. (8) The waking process of CIPs should be realized in a planned and purposeful way. (9) Establishment of a sleep-wake rhythm is the key to sleep management in post-CC management. (10) The spontaneous awakening trial, spontaneous breathing trial, and sleep management should be carried out together. (11) The depth of sedation should be adjusted dynamically in the late stage of CC period. (12) Standardized sedation assessment is the premise of rational sedation. (13) Appropriate sedative drugs should be selected according to the objectives of sedation and drug characteristics. (14) A goal-directed minimization strategy for sedation should be implemented. (15) The principle of analgesia must be mastered first. (16) Subjective assessment is preferred for analgesia assessment. (17) Opioid-based analgesic strategies should be selected step-by-step according to the characteristics of different drugs. (18) There must be rational use of non-opioid analgesics and non-drug-based analgesic measures. (19) Pay attention to evaluation of the psychological status of CIPs. (20) Cognitive function in CIPs cannot be ignored. (21) Delirium management should be based on non-drug-based measures and rational use of drugs. (22) Reset treatment can be considered for severe delirium. (23) Psychological assessment should be conducted as early as possible to screen-out high-risk groups with post-traumatic stress disorder. (24) Emotional support, flexible visiting, and environment management are important components of humanistic management in the intensive care unit (ICU). (25) Emotional support from medical teams and families should be promoted through"ICU diaries"and other forms. (26) Environmental management should be carried out by enriching environmental content, limiting environmental interference, and optimizing the environmental atmosphere. (27) Reasonable promotion of flexible visitation should be done on the basis of prevention of nosocomial infection. (28) ESCAPE is an excellent project for late stage of CC management.

Detection of SARS-CoV-2 IgG antibodies and inflammatory cytokines in saliva-a pilot study.

Objective: The pandemic caused by SARS-CoV-2 virus continues to have a profound effect worldwide. However, COVID-19 induced oral facial manifestations have not been fully described. We conducted a prospective study to demonstrate feasibility of anti-SARS-CoV-2 IgG and inflammatory cytokine detection in saliva. Our primary objective was to determine whether COVID-19 PCR positive patients with xerostomia or loss of taste had altered serum or saliva cytokine levels compared to COVID-19 PCR positive patients without those oral symptoms. Our secondary objective was to determine the correlation between serum and saliva COVID-19 antibody levels. Materials and methods: For cytokine analysis, saliva and serum were obtained from 17 participants with PCR-confirmed COVID-19 infection at three sequential time points, yielding 48 saliva samples and 19 paired saliva-serum samples from 14 of the 17 patients. For COVID-19 antibody analyses, an additional 27 paired saliva-serum samples from 22 patients were purchased. Results: The saliva antibody assay had 88.64% sensitivity [95% Confidence Interval (CI) 75.44%, 96.21%] to detect SARS-CoV-2 IgG antibodies compared to serum antibody. Among the inflammatory cytokines assessed - IL-6, TNF-α, IFN-γ, IL-10, IL-12p70, IL-1ß, IL-8, IL-13, IL-2, IL-5, IL-7 and IL-17A, xerostomia correlated with lower levels of saliva IL-2 and TNF-α, and elevated levels of serum IL-12p70 and IL-10 (p < 0.05). Loss of taste was observed in patients with elevated serum IL-8 (p < 0.05). Conclusions: Further studies are needed to construct a robust saliva-based COVID-19 assay to assess antibody and inflammatory cytokine response, which has potential utility as a non-invasive monitoring modality during COVID-19 convalescence.

[Materia medica illustrations related to the regional names in Shandong province in Ben Cao Tu Jing].

Ben Cao Tu Jing had 48 materia medica illustrations related to the regional names in Shandong province. It was found that 42 of them were plant medicinal materials, distributed in seven areas in Shandong province. This study examined these illustration of plant medicinal materials and found that 26 species of these illustration of plant medicinal materials were identified with three genera and 11 illustrations were unverified. Most materia medica illustrations relating to the regional names in Shandong province were found mainly in Yanzhou, Qizhou and Zizhou. This indicated that materia medica were widely used in these areas in the Northern Song Dynasty. The haustorium of Cuscuta Chinensis were depicted in the "Shanzhou Tu Si Zi" and the habitat of wild poriacocos was described. This showed that the illustrators of Ben Cao Tu Jing might have conducted fieldwork and reflected on the main principles about how to identify materia medica in Ben Cao Tu Jing Zou Chi. Inconsistencies were found between the illustrations and the expressions of plant medicinal materials in some illustrations, such as Gui Jiu, Ginsen and Shan Zhu Yu. This suggested that in the Northern Song Dynasty Stemmacantha Uniflora, Belamcanda chinensis might have been mixed up with Dysosma and Pinellia Pedatisecta might have been mixed up with Pinellia Ternata. This was in line with the compiling theories of Su Song that they could be recorded together when the illustrations and literature were inconsistent with each other.

The Role of Oral Health in the Acquisition and Severity of SARS-CoV-2: A Retrospective Chart Review.

Objective: Studies have shown that gingival crevices may be a significant route for SARS-CoV-2 entry. However, the role of oral health in the acquisition and severity of COVID-19 is not known. Design: A retrospective analysis was performed using electronic health record data from a large urban academic medical center between 12/1/2019 and 8/24/2020. A total of 387 COVID-19 positive cases were identified and matched 1:1 by age, sex, and race to 387 controls without COVID-19 diagnoses. Demographics, number of missing teeth and alveolar crestal height were determined from radiographs and medical/dental charts. In a subgroup of 107 cases and controls, we also examined the rate of change in alveolar crestal height. A conditional logistic regression model was utilized to assess association between alveolar crestal height and missing teeth with COVID-19 status and with hospitalization status among COVID-19 cases. Results: Increased alveolar bone loss, OR = 4.302 (2.510 - 7.376), fewer missing teeth, OR = 0.897 (0.835-0.965) and lack of smoking history distinguished COVID-19 cases from controls. After adjusting for time between examinations, cases with COVID-19 had greater alveolar bone loss compared to controls (0.641 ± 0.613 mm vs 0.260 ± 0.631 mm, p < 0.01.) Among cases with COVID-19, increased number of missing teeth OR = 2.1871 (1.146- 4.174) was significantly associated with hospitalization. Conclusions: Alveolar bone loss and missing teeth are positively associated with the acquisition and severity of COVID-19 disease, respectively.

[Materia medica illustrations related to the regional names in Zhejiang province in Ben Cao Tu Jing].

Ben Cao Tu Jing had 38 materia medica illustrations related to the regional names in Zhejiang province. It was found that 30 of them were identified as being named after regional names in Zhejiang province, involving 20 families and 29 genera. One of the 38 materia medica illustrations was mineral medicine and seven of them were unverified. The twenty-five of these materia medica illustrations with regional names were found to be consistent with their names used today. Five of them came from similar names in Zhejiang province in the Northern Song Dynasty, another five of the 25 names were known with the names but not entity for the lack of full descriptions and drawings. It was found that the drawing and the text of "Ming Zhou Huang Yao" and "Qin Zhou Hong Yao" in Ben Cao Tu Jing were reversed. By comparing the materia medica illustrations related to regional names in Da Guan Ben Cao by Liu Jia and Zheng He Ben Cao by Zhang Huicun, the name and the illustration of "Jin Zhou Bei Mu" in Zheng He Ben Cao by Zhang Huicun was more believable than "Yue Zhou Bei Mu" in Da Guan Ben Cao by Liu Jia. "Tai Zhou Wu Yao" and "Zhe Ba Wei", as genuine medicinal materials in Zhejiang, can be traced back to the illustrations of "Tai Zhou Wu Yao", "Yue Zhou Bai Zhu", "Mu Zhou Mai Dong", "Wen Zhou Peng 'e Shu", "Yue Zhou Bei Mu" and "Tian Tai Wu Yao" in Ben Cao Tu Jing. These findings provided text and drawing literature of herbs in the Song Dynasty for the research of genuine medicinal materials and their characteristics in Zhejiang province. They also showed that the utilization and development of the resources of traditional Chinese medicine in Zhejiang in the Northern Song Dynasty mainly focused on the coastal areas.

Differences in Muscle Quantity and Quality by HIV Serostatus and Sex.

OBJECTIVE: People with HIV (PWH) experience greater declines in both muscle function and muscle mass with aging. Whether changes in muscle quality and quantity with aging differ between men and women with HIV and the implications on muscle function are not established. DESIGN: In coordinated substudies of the Multicenter AIDS Cohort Study and Women's Interagency HIV Study, participants completed physical function and falls assessments; total trunk/thigh density, inversely related to fatty infiltration, and area were quantified from computed tomography (CT) scans. METHODS: Generalized linear models were used to explore variables affecting density/area, and associations between area/density and physical function and falls. RESULTS: CT scans were available on 387 men (198 PWH) and 184 women (118 PWH). HIV serostatus was associated with greater lateralis, paraspinal, and hamstring area, but lower psoas area and density. Older age and female sex were associated with smaller trunk muscle area and lower density. Both lower muscle area and muscle density were associated with several measures of impaired physical function. The odds of falling were lower with greater hamstring density, but not associated with other measurers of muscle area or density. CONCLUSIONS: In summary, older adults with HIV appear to have smaller and less dense (fattier) psoas, a key component in truncal stability and hip flexion that could have implications on physical function. The longitudinal associations of muscle area and density with physical function require careful investigation, with a particular focus on characteristics and interventions that can preserve muscle area, density, and function over time.

[Development of a nomogram for predicting the risk of colorectal advanced adenomas].

Objective: To explore the risk factors of colorectal advanced adenomas (AA) and construct a nomogram to predict the risk of colorectal AAs. Methods: Clinical data of patients were retrospectively collected who underwent their first colonoscopy from January 2017 to December 2020 in the First Affiliated Hospital of Nanjing Medical University and were pathologically confirmed harboring colorectal polyps. A credible random split-sample method was used to divide data into training and validation cohorts (split ratio=7∶3). Univariate and multivariate logistic regression analysis were used to identify the predictors of colorectal advanced adenomas, and a nomogram was developed based on the above results. The validation cohort was used for internal validation of the nomogram. The discriminatory value of the nomogram was evaluated using the area under the receiver operating characteristic (ROC) curve (AUC). The consistency between actual outcomes and predicted probabilities was evaluated by the calibration curve. The clinical validity of the model was evaluated by the decision analysis curve (DCA). Results: A total of 1 936 patients with colorectal polyps were eligible. Including 1 356 patients in the training cohort (840 males and 516 females), and 580 patients in the validation cohort (379 males and 201 females), with the mean ages of (57.4±9.8) and (57.6±9.7) years, respectively. There were 1 502 (77.6%) patients without AAs and 434 [22.4%,1-9 mm 73(16.8%) cases、>9-<20 mm 271(62.5%) cases、≥20 mm 90(20.7%) cases] patients with AAs. The regression analysis found that age (OR=1.018, 95%CI:1.003-1.033), fatty liver (OR=1.870, 95%CI:1.274-2.744), low-density lipoprotein (LDL) (OR=1.378, 95%CI:1.159-1.637), fecal occult blood test (FOBT) (OR=2.597, 95%CI:1.857-3.631), and location of adenomas [proximal (OR=2.869, 95%CI:1.727-4.764), distal (OR=2.791, 95%CI:1.721-4.527)] were identified as predictors of colorectal AAs. The AUC of the nomogram was 0.664 (95%CI:0.630-0.698) in the training cohort and 0.640 (95%CI:0.587-0.693) in the validation cohort. The calibration curve showed good consistency between the predicted and actual risk, and the Hosmer-Lemeshow (H-L) test P value was 0.830 and 0.150 in the training cohort and the validation cohort. DCA demonstrated that the nomogram had a better clinical application value. Conclusions: A nomogram with five predictors, including age, fatty liver, LDL, FOBT, and location of adenomas, helped predict the risk of colorectal AAs in patients with polyps and implemented colorectcal cancer stratified screening strategy for colonoscopy in the high-risk population.

[The quality control standards and principles of the application and training of critical ultrasonography].

Critical ultrasonography is widely used in ICU and has become an indispensable tool for clinicians. However, besides operator-dependency of critical ultrasonography, lack of standardized training mainly result in the physicians' heterogenous ultrasonic skill. Therefore, standardized training as well as strict quality control plays the key role in the development of critical ultrasonography. We present this quality control standards to promote better development of critical ultrasonography.

[Types of medicine paintings in herbaceous and woody medicines in Ben Cao Tu Jing].

A total of 568 paintings of herbaceous plants and woody plants as medicine were involved in Ben Cao Tu Jing, accounting for 60% of the total drug illustrations and 76% of the botanical medicine paintings. These medicinal paintings can be classified into four types: original plant paintings, medicinal material paintings, plant and medicinal material paintings, and plant and their habitat paintings. The original plant paintings can be specifically divided into five sections: the whole plant paintings with roots, partial aerial part paintings with roots, plant paintings with ground lines, rootless plant paintings, and broken branch paintings. Among them, the drawings of " the broken branch paintings " and " the whole plant paintings with roots " are consistent with the basic principles of collecting plant specimens. Additionally, "the plant and medicinal material paintings " and "the medicinal material paintings "reflect that they were drawn based on the market survey of medicinal materials or collected medicinal materials specimens. These medicine painting demonstrate rich characteristics of medicinal plants and medicinal materials and a high artistic quality with realistic details.These paintings in Ben Cao Tu Jing echoes Tu Jing, combine the art of painting with the cognition ofnatural science, as the rudiment of early paintings of plant science.
