Taxifolin (TAX) is a natural compound known for its liver protection effect, but the mechanism remains unknown. Phosphorylated proteomics analyses discovered that the phosphorylation level of NDRG1 at T328 was a key event of TAX-improved liver fibrosis. We established models with NDRG1 knockout (KO) in vivo and in vitro, demonstrating that NDRG1 KO attenuated the development of hepatocyte injury, and combining NDRG1 KO and TAX administration did not result in a reduction in protection against liver injury. Cellular thermal shift assay and surface plasma resonance analysis showed that TAX directly binds to NDRG1 rather than its upstream kinase, subsequently demonstrating that TAX regulated phosphorylation of NDRG1 at T328 through binding to its C289 site. NDRG1 T328A (phosphorylated mutation) and T328E (mimic phosphorylation) in vivo and in vitro confirmed that pNDRG1T328 exacerbates hepatocyte injury along with DNA damage, inflammatory response, and apoptosis, thereby contributing to hepatic stellate cells (HSCs) activation. In contrast, TAX can inhibit the above pathological abnormalities and block hepatocyte injury-triggered HSCs activation and fibrosis. Overall, TAX is a potent liver protection drug primarily targeting NDRG1 and inhibiting pNDRG1T328 in hepatocytes.

ObjectiveTo observe clinical effectiveness and safety of lumbar oscillatory manipulation in the treatment of patients with lumbar disc herniation. MethodsThis study recruited 90 lumbar disc herniation patients who were randomly divided into 45 cases each in the treatment group and the control group. The treatment group was given lumbar oscillatory manipulation, while the control group was given traditional lumbar obliquely pulling manipulation, and both groups were treated twice a week for 4 weeks. The Oswestry dysfunction index (ODI) score, lumbar spine mobility, and the absolute values of difference in hardness between the left and right sides of the lumbar erector spinae muscle were compared between groups of patients before treatment and after 2 and 4 weeks of treatment; the shear wave elastic modulus of multifidus muscle and abdominal muscle thickness were compared between groups before treatment and after 4 weeks of treatment; the clinical effectiveness of the treatment was compared, and the safety evaluation was carried out. ResultsCompared with the group before treatment, the ODI scores and the the absolute values of difference in hardness between the left and right sides of the lumbar erector spinae muscle decreased after 2 and 4 weeks treatment in both groups, and the mobility of the lumbar vertebrae in all directions of anterior flexion, posterior extension, left lateral flexion, and right lateral flexion increased; the shear wave elastic modulus of bilateral multifidus muscles of the fourth lumbar vertebral segments decreased, and the thickness of abdominal muscle increased after 4 weeks of treatment in both groups (P<0.05). Compared with the control group, the ODI score of the treatment group decreased after 2 weeks of treatment, and the shear wave elastic modulus value of bilateral multifidus muscle of the fourth lumbar vertebral segment decreased and the thickness of abdominal muscle increased after 4 weeks of treatment (P<0.05). The total effective rate was 90.48% (38/42) in the treatment group and 71.43% (30/42) in the control group, and the clinical effectiveness of the treatment group was better than that of the control group (P<0.05). No adverse events occurred in both groups during the study. ConclusionLumbar oscillatory manipulation is superior to traditional lumbar obliquely pulling manipulation in relieving symptoms of lumbar disc herniation and improving lumbar spine function, which may be related to its improvement in the elasticity of the multifidus muscle.

Objective:To investigate the efficacy of anatomical resection (AR) in the early stages of treating solitary hepatocellular carcinoma (HCC) combined with liver cirrhosis with a diameter of ≤5 cm in comparison to different surgical methods of preferential hepatic parenchymal preservation (non-anatomical liver resection, NAR).Methods:The clinical data of 1 390 cases with solitary HCC combined with liver cirrhosis at an early stage who underwent liver resection at Mengchao Hepatobiliary Hospital of Fujian Medical University and six other medical centers from September 2013 to May 2019 were retrospectively analyzed. Patients were divided into the AR group (486 cases) and the NAR group (904 cases) and the wide surgical margin (WSM) group (745 cases) and the narrow surgical margin (NSM) group (645 cases) according to whether they received AR and the width of the surgical margin (1 cm). The basic information of the patients, preoperative evaluation index data, and postoperative follow-up (follow-up every 3 months) were collected. The Kaplan-Meier method was used to plot the survival curve.The log-rank test was used to compare the difference in survival between the two groups. The Cox proportional hazards regression model was used to analyze the factors affecting the prognosis. Propensity score matching (PSM) was applied to reduce intergroup bias.Results:The overall survival (OS) rates for all patients at 1, 3, and 5 years were 95.5%, 79.9%, and 63.5%, respectively. The recurrence-free survival (RFS) rates were 81.5%, 59.0%, and 43.7%, respectively. There was a statistically significant difference in RFS rate between the AR group and the NAR group prior to PSM, but no statistically significant difference in OS rate (RFS rate: 47.0% vs. 41.9%, P<0.05; OS rate: 64.4% vs. 62.9%, P>0.05). The postoperative RFS rate and OS rate were significantly superior in the WSM group than those of the NSM group (RFS rate: 47.8% vs. 37.2%, P<0.001; OS rate: 69.0% vs. 57.3%, P<0.001). There was no statistically significant difference in OS rate and RFS rate between the AR group and the NAR group following PSM (RFS: 46.3% vs. 45.1%, P>0.05; OS rate: 64.0% vs. 64.3%, P>0.05).The 5-year OS and RFS rates in the WSM group were 66.8% and 60.2%, respectively. The 5-year OS and RFS rates for the NSM group were 48.7% and 41.4%, respectively, with a statistically significant difference ( P<0.05). Cox multivariate analysis indicated that serum albumin, tumor diameter, microvascular invasion, and surgical margin were independent prognostic factors affecting OS and RFS. The Child-Pugh grade and satellite lesions were independent prognostic factors affecting OS. Conclusion:Anatomical liver resection is not an independent risk factor for prognosis, but the state of the resection margin determines the prognosis of patients with solitary HCC combined with cirrhosis. Therefore, hepatic resection margins should be prioritized in such patients.

Objective:To identify the bacteria isolated from sepsis patients in a tertiary hospital in Shanghai and analyze their antimicrobial resistance features.Methods:This study included 439 patients with clinically diagnosed sepsis who underwent microbiological culture in a tertiary hospital in Shanghai from July 2021 to October 2024. Results of microbiological culture and antimicrobial susceptibility testing were retrospectively collected and analyzed. Differences between groups were analyzed using Chi-square test and Fisher′s exact test. Results:The positive rate of microbiological culture was 49.0% (215/439). The positive rate of blood culture was 24.1% (93/386) and 100 strains were isolated from the samples, including 57 Gram-negative bacteria (57.0%). The predominant isolates in blood samples were Escherichia coli, Klebsiella pneumoniae, and coagulase-negative staphylococci. The positive rate of bacterial culture from bronchoalveolar lavage fluid samples was 84.1% (37/44), with Klebsiella pneumoniae, Acinetobacter baumannii, and Pseudomonas aeruginosa being the predominant strains. The positive rate of bacterial culture from urine samples was 35.6% (127/357), with Escherichia coli, Klebsiella pneumoniae, and Enterococcus faecium being the most common. Escherichia coli, Klebsiella pneumoniae, Enterococcus faecium, coagulase-negative staphylococci, Pseudomonas aeruginosa, and Acinetobacter baumannii exhibited high resistance rates to fluoroquinolones [46.8% (29/62)-97.0% (32/33)]. The resistance rates of Acinetobacter baumannii to most commonly used antibiotics were >80.0%. The resistance rates of Escherichia coli and Klebsiella pneumoniae to the third-generation cephalosporins ranged from 41.8% (28/67) to 66.0% (31/47). Carbapenem resistance was observed in 38.1% (24/63)-40.3% (25/62) of Klebsiella pneumoniae isolates, and most of the isolates from bronchoalveolar lavage fluid samples showed a higher resistance rate than those from blood or urine samples ( P<0.05). Conclusions:The positive rate of bacterial culture is nearly 50% in this study, with Gram-negative bacteria being the most common. Six major pathogenic bacteria exhibit high resistance rates to fluoroquinolones. Klebsiella pneumoniae isolates have high resistance rates to the third-generation cephalosporins and carbapenems, with significant differences in the resistance rate between isolates from different samples, and it should be cautious to choose the third-generation cephalosporins and carbapenems in clinical practice.

Objective:To analyze the efficacy of phantom-less quantitative computer tomography (PL-QCT) for the diagnosis of osteoporosis in patients with lumbar degenerative diseases.Methods:From October 2021 to October 2023, a total of 1 248 patients with lumbar degenerative disease who did not receive anti-osteoporosis treatment in the Department of Spine Surgery, Tianjin Hospital were retrospectively analyzed. There were 520 males and 728 females, aged 62.31±9.37 years (range, 40-87 years), height 1.66±0.08 m (range, 1.43-1.89 m), weight 69.04±8.27 kg (range, 49-93 kg). The mean body mass index was 26.11±3.67 kg/m 2 (range, 14.40-37.11 kg/m 2). Dual-energy X-ray absorptiometry (DXA) and PL-QCT were used to diagnose osteoporosis, and the detection rates of the two diagnostic methods were compared. The receiver operating characteristic (ROC) curve of PL-QCT for the diagnosis of osteoporosis was drawn, the area under the curve (AUC) and 95% confidence interval (CI), sensitivity and specificity were calculated. Results:Among 1 248 patients with lumbar degenerative diseases, 626 (50.2%) were diagnosed as osteoporosis by PL-QCT, 423(33.9%) were diagnosed by spine DXA, 488(39.1%) were diagnosed by hip DXA and 539 patients(43.2%) were diagnosed by dual-site DXA. The detection rate of osteoporosis of PL-QCT was higher than that of spine DXA (χ 2=193.557, P<0.001), hip DXA (χ 2=322.201, P<0.001) and dual-site DXA (χ 2=94.683, P<0.001), and the difference was statistically significant. Taking the diagnostic results of spinal DXA for osteoporosis as a reference, the ROC curve of PL-QCT for the diagnosis of osteoporosis showed a sensitivity of 79%, a specificity of 81%, and an AUC and 95% CI of 0.82(0.79, 0.85). Taking the diagnostic results of hip DXA for osteoporosis as a reference, the ROC curve of PL-QCT for the diagnosis of osteoporosis showed a sensitivity of 85%, a specificity of 55%, and an AUC and 95% CI of 0.75(0.71, 0.78). Taking the diagnostic results of two-site DXA for osteoporosis as a reference, the ROC curve of PL-QCT for the diagnosis of osteoporosis showed a sensitivity of 72%, a specificity of 75%, and an AUC and 95% CI of 0.81(0.78, 0.83). Conclusion:Compared with DXA, PL-QCT has a higher detection rate of osteoporosis in patients with degenerative lumbar spine disease and good diagnostic efficacy.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

Objective:To construct a nomogram based on preoperative MRI imaging features for the prediction of muscle-invasive upper urinary tract urothelial carcinoma(UTUC)and evaluate its performance.Methods:This retrospective cohort study analyzed the clinical data of 99 UTUC patients treated at the First Affiliated Hospital of Nanjing Medical University from April 2018 to May 2024. Among them,69(69.7%)were male and 30(30.3%)were female,with a median age of 67.0 years. All patients underwent preoperative MRI and radical nephroureterectomy. According to postoperative pathology,tumors staged ≥ T 2 were assigned to the muscle-invasive group,and those staged ≤ T 1 were assigned to the non-muscle-invasive group. Baseline data,pathological information,and imaging characteristics were collected and compared between the two groups. Logistic regression analysis was performed to identify risk factors for muscle-invasive UTUC,and a nomogram was constructed. The diagnostic performance of the model was assessed using receiver operating characteristic(ROC)curves,calibration curves,and decision curve analysis(DCA). Results:Among the 99 patients,70(70.7%)were diagnosed with muscle-invasive UTUC,and 29(29.3%)with non-muscle-invasive UTUC. The muscle-invasive group had significantly larger tumor size[4.5(2.8,7.0)cm vs. 3.0(2.3,4.5)cm, P = 0.029],a higher incidence of multifocal tumors[37.1%(26/70)vs. 3.5%(1/29), P < 0.001],patchy tumors[30.0%(21/70)vs. 6.9%(2/29), P = 0.019],spiculated tumor margins[52.9%(37/70)vs. 17.2%(5/29), P = 0.001],tumor compression on renal parenchyma or periureteral/peripelvic fat[68.6%(48/70)vs. 10.3%(3/29), P < 0.001],high-grade pathology[92.9%(65/70)vs. 75.9%(22/29), P = 0.043],lymph node metastasis[28.6%(20/70)vs. 0, P = 0.001],and lymphovascular invasion[42.9%(30/70)vs. 10.3%(3/29), P=0.002]. The apparent diffusion coefficient(ADC)values[0.9(0.8,1.1)× 10 -3 mm2/s vs. 1.1(1.0,1.4)× 10 -3 mm2/s, P < 0.001]and normalized ADC(NADC)values[0.8(0.7,1.0)vs. 0.9(0.8,1.1), P = 0.002]were significantly lower in the muscle-invasive group. Univariate logistic regression identified multifocality,patchy tumor patterns,spiculated tumor margins,tumor compression on renal parenchyma or periureteral/peripelvic fat,and low NADC values as risk factors for muscle-invasive UTUC(all P < 0.05). Multivariate analysis revealed multifocality( OR = 17.903,95% CI 1.650 - 194.253, P = 0.018),tumor compression on renal parenchyma or perirenal / ureteral fat( OR = 14.690,95% CI 3.069 - 70.323, P < 0.001),and low NADC value( OR = 0.016,95% CI 0.001 - 0.471, P = 0.017)as independent risk factors. A nomogram was constructed based on these factors. The area under the ROC curve(AUC)of the model was 0.898(95% CI 0.838 - 0.957),with an optimal cutoff value of 0.639. The model showed an accuracy of 83.8%,sensitivity of 81.4%,and specificity of 89.7%. Calibration curves indicated good calibration,and DCA showed that the model provided substantial clinical net benefit. Conclusions:This study constructed a nomogram based on preoperative MRI features,including tumor multifocality,compression on renal parenchyma or periureteral/peripelvic fat and NADC value,which demonstrates good predictive performances for muscle-invasive UTUC.

Objective:To evaluate the diagnostic value of the vesical imaging-reporting and data system(VI-RADS)for determining muscle invasion in variant histology urothelial carcinoma(VUC)of the bladder.Methods:A retrospective analysis was performed on the pathological and imaging data of 518 bladder cancer patients admitted to Jiangsu Province Hospital between January 2013 and January 2023. Patients were stratified into pure urothelial carcinoma(PUC)group( n = 457)and variant urothelial carcinoma(VUC)group( n = 61)based on the presence of histological variants. In the PUC group,there were 390 males(85.3%)and 67 females(14.7%),with a mean age of(66.9 ± 11.2)years. Tumor characteristics included maximum diameter ≥ 30 mm in 149(32.6%),< 30 mm in 308(67.4%),multiple tumors in 147(32.2%),solitary in 310(67.8%),pedunculated morphology in 143(31.3%)and non-pedunculated in 314(68.7%). Histological grading identified high-grade tumors in 319 patients(69.8%)and low-grade tumors in 138(30.2%). Pathological stage distribution included 191 of T a(41.8%),127 of T 1(27.8%),76 of T 2(16.6%),47 of T 3(10.3%),and 16 of T 4(3.5%)patients. The VUC group included 61 patients,comprising 51 males(83.6%)and 10 females(16.4%),with a mean age of(65.8 ± 11.4)years. Tumor characteristics were maximum diameter ≥ 30 mm in 38(62.3%),< 30 mm in 23(37.7%),multiple tumors in 16(26.2%),solitary in 45(73.8%),pedunculated morphology in 11(18.0%)and non-pedunculated in 50(82.0%). Histological grading identified high-grade tumors in 59 patients(96.7%)and low-grade tumors in 2(3.3%). Pathological stage distribution included 3 of T a(4.9%),15 of T 1(24.6%),15 of T 2(24.6%),20 of T 3(32.8%),and 8 of T 4(13.1%)patients. No statistically significant differences were found between the two groups in gender,age,or tumor multiplicity( P > 0.05). Statistically significant differences were found in pathological grade,pathological stage,maximum tumor diameter,and pedunculated morphology( P < 0.05). Furthermore,an external validation cohort of 278 bladder cancer patients treated between February 2023 and February 2024 from multiple centers(Jiangsu Provincial People’s Hospital,The First Affiliated Hospital of Zhengzhou University,Union Hospital Tongji Medical College Huazhong University of Science and Technology,Jiangsu Provincial Hospital of Traditional Chinese Medicine,Suzhou Municipal Hospital,Huaian First People’s Hospital,Yixing People’s Hospital)was retrospectively analyzed to externally validate the performance of VI-RADS scoring in predicting muscle invasion of VUC. This cohort included a PUC subgroup of 241 patients,comprising 196 males(81.3%)and 45 females(18.7%),with a mean age of(68.0 ± 10.7)years. Tumor characteristics were maximum diameter ≥ 30 mm in 85(35.3%),< 30 mm in 156(64.7%),multiple tumors in 65(27.0%),solitary in 176(73.0%),pedunculated morphology in 76(31.5%)and non-pedunculated in 165(68.5%). Histological grading identified high-grade tumors in 175 patients(72.6%)and low-grade tumors in 66(27.4%). Pathological staging comprised 107 patients of T a(44.4%),78 of T 1(32.4%),22 of T 2(9.1%),22 of T 3(9.1%),and 12 of T 4(5.0%). The VUC subgroup consisted of 37 patients,comprising 29 males(78.4%)and 8 females(21.6%),with a mean age of(70.5 ± 9.5)years. Tumor characteristics were maximum diameter ≥ 30 mm in 23(62.2%),< 30 mm in 14(37.8%),multiple tumors in 9(24.3%),solitary in 28(75.7%),pedunculated morphology in 7(18.9%)and non-pedunculated in 30(81.1%). Histological grading identified high-grade tumors in 36 patients(97.3%)and low-grade tumors in 1(2.7%). Pathological staging comprised 1 patient of T a(2.7%),9 of T 1(24.3%),7 of T 2(18.9%),19 of T 3(51.4%),and 1 of T 4(2.7%). In this validation cohort,no significant differences were found in gender,age,tumor multiplicity,or pedunculated morphology between the PUC and VUC subgroups( P > 0.05). Significant differences were observed in pathological grade,pathological stage,and maximum tumor diameter( P < 0.05). Three radiologists independently reviewed and scored the multiparametric MRI(mp-MRI)in a blinded manner. Inter-reader agreement was assessed using the weighted kappa statistic. Differences in variables between the two groups were compared using t-tests,chi-square tests,or Fisher’s exact test. The diagnostic performance of VI-RADS for muscle invasion in VUC and PUC was comprehensively evaluated using receiver operating characteristic(ROC)curves,the area under the curve(AUC),and cut-off values determined by the Youden’s index. The DeLong test was used to assess whether the diagnostic performance of VI-RADS differed between VUC and PUC. Results:In the retrospective single-center cohort,the AUC of VI-RADS for assessing muscle invasion was 0.895(95% CI 0.864?0.922)in the PUC group,with a cut-off value of > 3,and the AUC was 0.896(95% CI 0.791-0.960)in the VUC group,with a cut-off value of > 3. The difference between the two groups was not statistically significant( P = 0.986). Using a VI-RADS score > 3 as the cut-off value,the accuracy,sensitivity,specificity,positive predictive value(PPV),and negative predictive value(NPV)for diagnosing muscle invasion status in the PUC group were 85.8%(392/457),70.5%(98/139),92.5%(294/318),80.3%(98/122),and 87.8%(294/335),respectively. The corresponding values for the VUC group were 82.0%(50/61),76.7%(33/43),94.4%(17/18),97.1%(33/34),and 63.0%(17/27).In the retrospective multicenter cohort,the AUC of VI-RADS for assessing muscle invasion was 0.891(95% CI 0.845?0.927)in the PUC group,with a cut-off value of > 2,and the AUC was 0.898(95% CI 0.754?0.973)in the VUC group,with a cut-off value of > 3. The difference between the two groups was not statistically significant( P = 0.897). Using a VI-RADS score > 3 as the cut-off value,the accuracy,sensitivity,specificity,PPV,and NPV for diagnosing muscle invasion status in the PUC group were 85.9%(207/241),58.9%(33/56),94.1%(174/185),75.0%(33/44),and 88.3%(174/197),respectively. The corresponding values for the VUC group were 81.1%(30/37),77.8%(21/27),90.0%(9/10),95.5%(21/22),and 60.0%(9/15).In the single-center cohort,the Kappa values for inter-reader agreement in assessing muscle invasion status using VI-RADS were 0.881( P < 0.01)for the PUC group and 0.941( P < 0.01)for the VUC group among the three readers. In the multicenter cohort,the Kappa values were 0.858( P < 0.01)for the PUC group and 0.838( P < 0.01)for the VUC group. Conclusions:VI-RADS demonstrates similarly high diagnostic performance for assessing muscle invasion in both PUC and VUC,which is applicable for diagnosing muscle invasion status in VUC,and shows good inter-reader agreement.

This study explored the mechanism of Xiangsha Liujunzi Decoction(XSLJZD) in the treatment of functional dyspepsia(FD) based on inositol-requiring enzyme 1(IRE1)/apoptosis signal-regulating kinase 1(ASK1)/c-Jun N-terminal kinase(JNK) pathway-mediated autophagy in interstitial cells of Cajal(ICC). Forty-eight SPF-grade male SD suckling rats were randomly divided into a blank group and a modeling group, and the integrated modeling method(iodoacetamide gavage + disturbance of hunger and satiety + swimming exhaustion) was used to replicate the FD rat model. After the model replications were successfully completed, the rats were divided into a model group, high-dose, medium-dose, and low-dose groups of XSLJZD(12, 6, and 3 g·kg~(-1)·d~(-1)), and a positive drug group(mosapride of 1.35 mg·kg~(-1)·d~(-1)), and the intervention lasted for 14 days. The gastric emptying rate and intestinal propulsion rate of rats in each group were measured. The histopathological changes in the gastric sinus tissue of rats in each group were observed by hematoxylin-eosin(HE) staining. The ultrastructure of ICC was observed by transmission electron microscopy. The immunofluorescence double staining technique was used to detect the protein expression of phospho-IRE1(p-IRE1), TNF receptor associated factors 2(TRAF2), phospho-ASK1(p-ASK1), phospho-JNK(p-JNK), p62, and Beclin1 in ICC of gastric sinus tissue of rats in each group. Western blot was used to detect the related protein expression of gastric sinus tissue of rats in each group. Compared with those in the blank group, the rats in the model group showed decreased body weight, gastric emptying rate, and intestinal propulsion rate, and transmission electron microscopy revealed damage to the endoplasmic reticulum structure and increased autophagosomes in ICC. Immunofluorescence staining revealed that the ICC of gastric sinus tissue showed a significant elevation of p-IRE1, TRAF2, p-ASK1, p-JNK, and Beclin1 proteins and a significant reduction of p62 protein. Western blot revealed that the expression levels of relevant proteins in gastric sinus tissue were consistent with those of proteins in ICC. Compared with the model group, the body weight of rats in the high-dose and medium-dose groups of XSLJZD was increased, and the gastric emptying rate and intestinal propulsion rate were increased. Transmission electron microscopy observed amelioration of structural damage to the endoplasmic reticulum of ICC and reduction of autophagosomes, and the p-IRE1, TRAF2, p-ASK1, p-JNK, and Beclin1 proteins in the ICC of gastric sinus tissue were significantly decreased. The p62 protein was significantly increased. Western blot revealed that the expression levels of relevant proteins in gastric sinus tissue were consistent with those of proteins in ICC. XSLJZD can effectively treat FD, and its specific mechanism may be related to the inhibition of the expression of molecules related to the endoplasmic reticulum stress IRE1/ASK1/JNK pathway in ICC and the improvement of autophagy to promote gastric motility in ICC.

Fritillariae Cirrhosae Bulbus is the dried bulb of perennial herbaceous plants in the Fritillaria genus(Liliaceae family) and is a representative traditional Chinese medicinal material with distinctive regional characteristics. Clinically, it is widely used in the treatment of dry cough, bronchial asthma, and other respiratory diseases, possessing significant medicinal and economic value and being highly esteemed in TCM. Currently, Fritillariae Cirrhosae Bulbus primarily relies on wild harvesting. However, due to excessive collection, its wild resources have drastically declined, and all source species have been classified as category Ⅱ in the List of National Key Protected Wild Plants, exacerbating the supply-demand imbalance in the market. To mitigate this issue, large-scale cultivation through the domestication of wild Fritillariae Cirrhosae Bulbus has become an inevitable trend. However, its strict environmental requirements, low propagation efficiency, high seedling mortality, and immature cultivation techniques have severely hindered industrialization. This study investigates the domestication process of Fritillariae Cirrhosae Bulbus, focusing on seed propagation, seedling cultivation, and medicinal material production. It also reviews the species and distribution of wild resources, their endangered status, market supply-demand dynamics, and the historical and current development of domestication. The findings indicate that enhancing propagation efficiency, optimizing cultivation models, and distinguishing between seed propagation and medicinal material production are key measures to accelerate the industrialization of domesticated Fritillariae Cirrhosae Bulbus. This research aims to promote the industrialization of Fritillariae Cirrhosae Bulbus domestication and provide a reference model for the conservation and sustainable utilization of rare and endangered medicinal plant resources.
