Atractylodes lancea is a perennial herbaceous plant of Asteraceae, with rhizomes for medical use. However, A. lancea plants from different habitats have great variability, and the germplasm resources of A. lancea are unclear and mixed during production. Therefore, it is urgent to protect new varieties of A. lancea. The distinctness, uniformity, and stability(DUS) testing of new plant varieties is the foundation of plant variety protection, and the DUS testing guidelines are the technical basis for variety approval agencies to conduct DUS testing. In this study, the phenotypic traits of 94 germplasm accessions of A. lancea were investigated considering the breeding and variety characteristics of A. lancea in China. The traits were classified and described, and 24 traits were preliminarily determined, including 20 basic traits that must be tested and four traits selected to be tested. The 20 basic traits included 3 quality traits, 5 false quality traits, and 12 quantitative traits, corresponding to 1 plant traits, 2 stem traits, 8 leaf traits, 6 flower traits, and 3 seed traits. The measurement ranges and coefficients of variation of eight quantitative traits were determined, on the basis of which the grading criteria and codes of the traits were determined and assigned. The guidelines has guiding significance for the trait evaluation, utilization, and breeding of new varieties of A. lancea.

The population aging and the coming of the information era are accompanied with the growing incidence of spinal degenerative diseases, which result in heavy social and economic burdens. Under the guidance of the tendon-bone theory, rich experience has been accumulated in the prevention and diagnosis of spinal degenerative diseases with traditional Chinese medicine(TCM), which demonstrates unique advantages. China's government has placed people's health in the strategic position of development, providing a favorable environment for the realization of healthy aging. The Healthy China 2030 advocates special actions for healthy bones. As China is facing an important period of demographic transition, the Traditional Chinese Medicine for Bone Health Program has emerged, combining the needs of the national health strategy and the advantages of TCM. This paper discusses the background and significance of the program. According to the theory of five body constituents and the characteristics of musculoskeletal system diseases, this paper constructs a theoretical system of "tendon-meridian-muscle-bone-marrow" to explain the structure and function of the musculoskeletal system. From the holistic view of TCM, this system shows not only the structure and function of the musculoskeletal system but also the patterns of disease development and the mechanism of TCM treatment. The system facilitates the research on not only the comorbidities related to bone health but also the occurrence, development, and outcome of diseases. In the management of chronic degenerative diseases, attention should be paid to the establishment and improvement of the disease prevention and control system in addition to the disease treatment alone. Finally, this paper introduces the characteristic advantages of TCM in the whole process of prevention, diagnosis, treatment, rehabilitation, and health maintenance of spinal degenerative diseases, aiming to enrich the connotation of the tendon-bone theory, provide ideas and implementation strategies for TCM clinical practice, and ultimately achieve the effective management of the diagnosis and treatment of spinal degenerative diseases.

This study rapidly identified and quantified the chemical components of the Wuzhuyu Decoction nanophase(WZYD-N) and suspension phase(WZYD-S) using ultra-high performance liquid chromatography coupled with triple quadrupole mass spectrometry(UPLC-QQQ-MS/MS). Based on preliminary pharmacodynamic experiments and network pharmacology analysis, the differential anti-inflammatory and analgesic activities of WZYD-N and WZYD-S were explored to understand their pharmacodynamic basis. WZYD-N and WZYD-S were separated by differential centrifugation-dialysis, and their particle size, Zeta potential, PDI, and morphology were characterized by dynamic light scattering and transmission electron microscopy. A method was established to quantify 23 representative components of WZYD using UPLC-QQQ-MS/MS, clarifying the differences in component content between the two phases. The anti-inflammatory and analgesic activities of WZYD-N and WZYD-S were preliminarily investigated using the acetic acid-induced enhanced capillary permeability inflammation model and the acetic acid writhing pain model. Network pharmacology was applied to screen the key anti-inflammatory and analgesic targets and active components of WZYD, and the relationship between the components and pharmacodynamics of WZYD-N and WZYD-S was analyzed based on quantitative results. The results showed that WZYD-N primarily consisted of spherical self-assembled aggregates around 200 nm, with a PDI of approximately 0.299 and a zeta potential of-22.1 mV. With an equivalent amount of crude drugs, obacunone and dihydroevocarpine were quantified in equal amounts in WZYD-N and WZYD-S. The content of rutaecarpine, evocarpine, rutaevine, limonin, and ginsenoside Ro was higher in WZYD-S, while 15 other components, including evodiamine, dehydroevodiamine, ginsenoside Re, 6-gingerol, and ginsenoside Rg_1, were higher in WZYD-N. Moreover, 6-dehydrogingerdione was low in both WZYD-N and WZYD-S. Preliminary pharmacodynamic experiments showed that WZYD-N could reduce the number of writhing responses and inhibit pain responses induced by acetic acid in mice, exhibiting analgesic effects similar to the WZYD group. WZYD-S could reduce the absorbance value of the intraperitoneal lavage fluid in mice, exhibiting anti-inflammatory effects comparable to the WZYD group. Network pharmacology analysis indicated that dehydroevodiamine, rutaecarpine, 6-gingerol, and ginsenoside Rg_1 might be the analgesic active components of WZYD, and limonin, rutaevine, and ginsenoside Ro might be the anti-inflammatory active components of WZYD. This study proposed a novel strategy for elucidating the pharmacodynamic basis of WZYD and innovating classical formulas.

In recent years, the clinical treatment of colorectal cancer(CRC) has made great progress, but chemoresistance is still one of the main reasons for reducing the survival rate of patients with colorectal cancer. Therefore, ameliorating chemotherapy resis-tance is an urgent problem to be solved. The purpose of this study was to investigate the regulatory role and related molecular mechanisms of hydroxysafflor yellow A(HSYA) in colorectal cancer cell proliferation, migration, and 5-fluorouracil(5-FU) chemoresistance. In this study, HCT116 and HT-29 cells were used as research subjects. Firstly, methyl thiazolyl tetrazolium(MTT) assay and colony formation assay were used to detect and analyze the effect of HSYA on the proliferation of CRC cells. Secondly, the effect of HSYA on the cell cycle in CRC cells was analyzed by cell cycle assay. Furthermore, the effect of HSYA on the migration of CRC cells was analyzed by wound-healing assay and Transwell assay. Based on the above, the influences of HSYA on 5-FU chemoresistance of CRC cells and related molecular mechanisms were explored and analyzed. The results showed that HSYA significantly inhibited the proliferation and migration of CRC cells, and arrested the cell cycle in G_0/G_1 phase. In addition, HSYA significantly ameliorated the chemoresistance of CRC cells to 5-FU. The results of acridine orange staining and Western blot showed that the autophagy activity of CRC cells in the HSYA and 5-FU combined treatment group was significantly higher than that in the 5-FU single drug treatment group. As compared with the 5-FU single drug treatment group, the phosphorylation levels of protein kinase B(Akt) and mammalian target of rapamycin(mTOR) in the HSYA and 5-FU combined treatment group were significantly reduced, indicating that the Akt/mTOR signaling pathway in the combined treatment group was down-regulated in CRC cells. In conclusion, HSYA may upregulate autophagy activity through the Akt/mTOR signaling pathway, thereby inhibiting the proliferation and migration of CRC cells and ameliorating the chemoresistance to 5-FU.

Breast cancer is currently one of the caneers with the highest incidence.Clinically, most breast eaneer patients often die due to distant metastasis.In the complex easeade of metasta¬sis, the formation of the pre-metastasis niche ( PMN) has been considered to he cnrcial in the process of distant metastasis of tumors in recent years.Tumors at the primary site secrete tumor- derived secretory factors (TDSF) , extracellular vesicles ( EV) and so on to metastasize target organs.thereby changing the mi- croenvironment of the target organs to adapt to the subsequent distant metastasis of the tumor.Breast cancer is a kind of cancer number of studies have revealed the mechanism of the breast cancer pre-metastatic niche, showing that inhibiting the PMN can reduce breast cancer metastasis.The multi-target and multi- component features of traditional Chinese medicine have been re¬ported to effectively interfere with the formation of PMN.This review summarizes the breast cancer's mechanism of lung pre- metastatic niche formation and traditional Chinese medicine in¬tervention.

Objective: To Summarize the safety, clinical outcome and technical evolution of laparoscopic gastric cancer surgery. Methods: A retrospective cohort study was carried out. Clinical data of 3012 patients who underwent laparoscopic radical gastrectomy for gastric cancer from January 2010 to March 2022 at Department of General Surgery, the First Affiliated Hospital of Nanjing Medical University were retrospectively collected and analyzed. Case inclusion criteria were gastric malignancies confirmed by pathology, without distant metastasis by examination before operation and exploration during operation, patients undergoing laparoscopic radical gastrectomy, intact function of important organs and with complete data. Exclusion criteria were patients who underwent emergency gastric cancer resection due to gastric bleeding, perforation or obstruction, etc., tumor found to invade adjacent organs such as pancreas or transverse colon during the operation, conversion to open surgery during the operation, those who had other malignant tumors (except thyroid cancer) within 5 years, and those had severe cardiopulmonary, liver, or kidney insufficiency before surgery. Outcomes included: (1) baseline information of patients; (2) trend of the quantity of laparoscopic radical gastrectomy year by year; (3) evolution of the mode of digestive tract reconstruction; (4) periopertive outcome short-term complication was defined as complication occurring within 30 days after operation and classified accordiny to the clavien-Dindo criteria; and (5) 5-year overall survival. SPSS software was used for statistical analysis. Continuous variables that obeyed the normal distribution were expressed in the form of Mean±SD. Days of hospital stay that did not follow a normal distribution were expressed as median (Q₁,Q₃), and the Mann-Whiney U test was used for comparison. Discrete variables were expressed as cases (%), and chi-square test or rank sum test was used for comparison between groups. Linear regression analysis was used to analyze the relationship between the amount of surgery and the year of surgery. Kaplan-Meier method and log-rank test were used for survival analysis. Two-tailed P<0.05 was considered as statistically significant. Results: Among the 3012 cases, 2114 were male and 898 were female. The patients' average age at surgery was (61.1±10.7) years old. According to the number of cumulative cases, the patients were divided into three groups: early, intermediate and late, with 1004 patients in each group. The early group consisted of patients undergoing operation from January 2010 to October 2018, the intermediate group consisted of patients undergoing operation from October 2018 to January 2021, and the late group consisted of patients undergoing operation from January 2021 to March 2022. (1) General information: There were 691 (68.8%), 699 (69.6%) and 724 (72.1%) male patients in early, intermediate and late groups respectively; the average age increased from 56.6 years in 2010 to 62.8 years in March 2022. As for the tumor stage T1, T2, T3, T4, there were 49.0%, 14.4%, 23.9% and 12.6% in the early group; 47.5%, 12.9%, 26.9% and 12.6% in the intermediate group; 39.7%, 14.6%, 30.0%, and 15.6% in the late group, respectively. Patients with N0, N1, N2, N3a, N3b stage were 56.8%, 13.7%, 13.4%, 11.0%, and 5.0% in the early group; 55.7%, 12.9%, 12.8%, 11.6%, and 6.9% in the intermediate group; 51.0%, 16.1%, 12.8%, 12.5%, and 7.5% in the late group, respectively. (2) Year-by-year change in the number of gastric cancer operations: From 19 cases per year in 2010 to 786 per year in 2021, the annual number of gastric cancer operations was proportional to the year of operation (y=47.505x, R²=0.67). The proportion of patients with stage I disease showed a fluctuating downward trend over time, while the proportion of patients with stage III disease increased slightly, accounting for 34% until March 2022. (3) Evolution of digestive tract reconstruction methods: Except in 2010, the digestive tract reconstruction method of distal gastrectomy focused on Billroth-II+Braun anastomosis among patients undergoing laparoscopic gastric cancer surgery in other years, whose proportion had gradually increased from less than 20% in 2016 to about 70% after 2021; the gastrointestinal reconstruction methods after total gastrectomy had gradually increased in π anastomosis and overlap anastomosis since 2016, of which π anastomosis reached about 65% in 2019, and overlap anastomosis reached almost 30% in 2020; the anastomosis methods after proximal gastrectomy had been mainly double-channel anastomosis (54%) and esophagogastric anastomosis (30%) since 2016, and double-channel anastomosis accounted for up to 70% in 2019. (4) Operation time: The operation time of early, intermediate and late group was (193.3±49.8) min, (186.9±44.3) min and (206.7±51.4) min respectively. Intermediate group was significantly shorter than early group (t=3.005, P=0.003), while late group was significantly longer than early group (t=5.875, P<0.001) and intermediate group (t=9.180, P<0.001). (5) Postoperative hospital stay: The median length of hospital stay for gastric cancer patients in early, intermediate and late groups was 9 (8, 11) d, 8 (7, 10) d, and 8 (7.5, 10) d respectively. The postoperative hospital stay of intermediate group and late group was significantly shorter than that of early group (Z=-12.467, Z=-5.981, both P<0.001), but there was no significant difference between intermediate group and late group (Z=0.415,P=0.678). (6) Postoperative complication: The morbidity of short-term complication in early, intermediate and late group was 20.4% (205/1004), 16.2% (163/1004), and 16.2% (162/1004) respectively, and above morbidity of intermediate group and late group was significantly lower than that of early group (χ²=5.869, P=0.015; χ²=6.165, P=0.013), while there was no significant difference between intermediate group and late group (χ²=0.004,P=0.952). The morbidity of short-term complication of grade IIIor higher was 8.0% (80/1004), 7.6% (76/1004), and 4.9% (49/1004) in early, intermediate and late group respectively, and above morbidity of late group was significantly lower than that of early and intermediate group (χ²=7.965, P=0.005; χ²=6.219,P=0.013), while there was no significant difference between intermediate group and early group (χ²=0.111,P=0.739). (7) Survival analysis: The follow-up deadline for survival data was December 31, 2021, and the median follow-up time was 29.5 months. The overall 5-year survival rate of all the patients was 74.7%. The 5-year survival rates of stage I, II and III patients were 92.0%, 77.2%, and 40.3% respectively and 5-year survival rates of patients with stage IA, IB, IIA, IIB, IIIA, IIIB and IIIC were 93.2%, 87.8%, 81.1%, 72.7%, 46.2%, 37.1%, and 34.0% respectively. Conclusions: The number of laparoscopic gastric cancer operation in our center is increasing year by year. With the maturity of laparoscopic technology, the morbidity of complication in laparoscopic gastric cancer surgery is decreasing.

OBJECTIVE: To compare the clinical efficacy of lengthened proximal femoral nail anti-rotation(PFNA) combined with minimally invasive percutaneous plate osteosynthesis(MIPPO) and common PFNA in the treatment of AO-A3.3 intertrochanteric fracture. METHODS: The clinical data of 58 patients with AO-A3.3 intertrochanteric fracture treated from January 2015 to April 2020 were retrospectively analyzed. Among them, 27 patients were treated with extended PFNA + MIPPO plate to reconstruct the lateral wall (group A), and 31 patients were treated with closed reduction and PFNA fixation (group B). The bleeding volume, operation time, femoral neck length and tip apex distance(TAD), fracture healing time and postoperative complications were observed and compared between two groups. Harris score was used to evaluate hip joint function 10 months after operation. RESULTS: All patients were followed up for 12 to 28 months. The incision healed well after operation. The bleeding volume and operation time of group A were significantly more than that of group B (P<0.05), and the fracture healing time of group A was significantly less than that of group B(P<0.05). There was no significant difference in the length of femoral neck between two groups at 2 days after operation(P>0.05). The length of femoral neck at 6 months after operation in each group was shorter than that at 2 days after operation(P<0.05), and the shortening of femoral neck at 6 months after operation in group B was significantly shorter than that in group A(P<0.05). There was no significant difference in TAD values between two groups at the same time point(P>0.05) at 2 days and 6 months after operation. There was no significant difference in TAD values between 2 days and 6 months after operation(P>0.05). The incidence of complications in group B was significantly higher than that in group A(P<0.05). The Harris scores of hip joint function in group A were higher than those in group B 10 months after operation (P<0.05). CONCLUSION Compared with the treatment of AO-A3 femoral intertrochanteric fracture with closed reduction and PFNA fixation, the lengthened PFNA combined with MIPPO small plate for reconstruction and fixation of the lateral wall can promote the fracture healing, improve the patient's functional recovery, and significantly reduce the complications.

Objective:To study the soil physical and chemical properties， microorganisms， and metabolites in different culture environments of Gastrodia elata， so as to provide scientific basis for subsequent cultivation of G. elata in multiple environments. Method:The tubersphere soil of G. elata cultured in different environments was collected for analyzing the soil nutrients， microbial numbers， and metabolite differences using the agrochemical method， plate-count method， and gas chromatography-time-of-flight mass spectrometry （GC-TOF-MS）-based non-targeted metabonomic approach. Result:The analysis of soil physical and chemical properties revealed the highest soil moisture， pH， available potassium， and available phosphorus in the spinney and the highest electrical conductivity， total nitrogen， alkali-hydrolyzable nitrogen， and organic matter in the pinewood. As demonstrated by the quantitative analysis of soil microorganisms， the cultivable microorganisms were bacteria， actinomycetes， and fungi， with the bacterial population and total microbial biomass in the spinney and the number of fungi and actinomycetes in the barren slope detected to be the largest. The ratio of bacteria to fungi （B/F value） in the pinewood was the highest， while that in the barren slope was the lowest. The results of metabonomic research demonstrated that the compositions and quantities of soil metabolites in the spinney （Z group）， pinewood （S group）， and barren slope （HD group） varied. Through comparisons between S and Z groups， between HD and Z groups， as well as between HD and S groups by orthogonal partial least squares discriminant analysis （OPLS-DA）， 18， 35， and 24 differential metabolites were separately screened out， and the Kyoto Encyclopedia of Genes and Genomes （KEGG） pathway enrichment analysis yielded 5， 9， and 13 metabolic pathways. There existed a significant causal relationship of the soil physical and chemical properties and microbial numbers with the metabolites. Conclusion:The soil physical and chemical properties， microbial numbers， and metabolite changes differed significantly in different culture environments of G. elata， which were sorted by the suitability in a descending order as follows： spinney > pinewood >barren slope. The soil physical and chemical properties and microbial numbers are the crucial factors driving changes in soil metabolites， suggesting that regulating the soil physical and chemical characteristics and microbial characteristics in the culture environment is an important mechanism for maintaining the G. elata-soil-microbial symbiotic system.

In recent years, with the development of laparoscopic technology and the improvement of surgeons' skill, laparoscopic radical gastrectomy for early gastric cancer has been widely achieved in large centers worldwide. But digestive reconstruction under laparoscopy is still the most important for totally laparoscopic surgery. At present, the oncological safety of totally laparoscopic gastrectomy for early gastric cancer has been preliminarily confirmed. Digestive tract reconstruction after totally laparoscopic distal gastrectomy includes Billroth-Ⅰanastomosis, Billroth-Ⅱ anastomosis and Roux-en-Y anastomosis; after proximal gastrectomy, it includes traditional esophagogastric anastomosis and evolutionary anti-reflux surgery;for total gastrectomy, itincludes esophageal jejunal anastomosis by using circular stapler and linear stapler. These reconstruction methods have their own characteristics, and no consensus has been reached at present. However, in clinical practice, it is necessary to focus on the patient, adjust measures to local conditions, and select the appropriate digestive tract reconstruction method on the premise of ensuring the radical cure of tumors.
