Primary liver cancer is a common malignant tumor in China. The current main treatment methods include surgical resection, liver transplantation, interventional therapy, radiofrequency ablation, chemotherapy, targeted therapy, and immunotherapy. Yttrium-90 microsphere selective internal radiation therapy (90Y-SIRT) represents a critical treatment option for converting unresectable intermediate to advanced hepatocellular carcinoma. This report details a case of a patient with a giant hepatocellular carcinoma in the right lobe treated with 90Y resin microsphere at the Third Affiliated Hospital of Sun Yat-sen University. Post-treatment, the tumor showed significant necrosis and reduction in size, with a marked decrease in alpha fetoprotein (AFP) levels and notable improvement in clinical symptoms. The case highlights the substantial efficacy of 90Y-SIRT in controlling tumor progression and enhancing patient quality of life.

Pinellia ternata, belonging to the Pinellia genus within the Araceae family, is a medicinal plant due to its tubers. There are severe issues with unclear germplasm and mixed varieties in its cultivation, necessitating urgent new variety protection efforts. The distinctness, uniformity, and stability (DUS) testing of the plant variety is the basis for protecting new plant varieties, and the DUS test guidelines are the technical basis for DUS testing. To develop the DUS test guidelines for P. ternata, agronomic traits of 229 germplasm of P. ternata were observed and measured during its two growth stages over the years, and each character was graded and described. A total of 38 traits were selected as the test traits of the DUS test guideline for P. ternata. There were three plant traits, 19 leaf traits, six flower traits, two fruit traits, two tuber traits, five bulbil traits, and one ploidy trait. These traits could be divided into 22 quality characters, 12 quantitative characters, and four pseudo-quantitative characters, as well as seven groups, including plants, leaves, flowers, fruit, tubers, bulbils, and ploidy. By searching for standard traits, 10 standard varieties were ultimately determined. Preparing these guidelines will have great significance for reviewing and protecting P. ternata varieties, safeguarding breeders' rights, and promoting the development of the P. ternata industry.

ObjectiveTo investigate the potential mechanisms of Zhimu (Anemarrhena asphodeloides)-Huangbai (Phellodendron amurense) medicinal pair in alleviating postmenopausal osteoporosis (PMOP). MethodsSixty unpregnant female SD rats were randomly divided into five groups, blank group, model group, low-dose Zhimu-Huangbai group, high-dose Zhimu-Huangbai group, and estradiol group, with 12 rats in each group. Except for the blank group, all other groups had their ovaries removed to create PMOP rat models, while the blank group only had the fat tissue around the ovaries removed. One week after the ovarian removal, the low-dose and high-dose Zhimu-Huangbai groups received concentrated solution of Zhimu and Huangbai with 1.8, 7.2 g/(kg·d) via gavage, the estradiol group received estradiol solution 0.09 mg/(kg·d) via gavage, and the blank group and the model group received 10 ml/(kg·d) of normal saline via gavage, once daily for 12 weeks. Before sampling, the body mass of the rats was recorded, and uterine tissue was taken to calculate the uterine index. The levels of interleukin-1β (IL-1β), interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) in serum were detected by ELISA; micro CT was used to examine the parameters of femoral microstructure, including bone volume/tissue volume (BV/TV), trabecular number (Tb.N), trabecular thickness (Tb.Th), bone mineral density (BMD), trabecular separation (Tb.Sp), and cortical bone area (Ct.Ar). HE staining was used to observe pathological changes in the femur; RT-qPCR was used to detect the mRNA expression of osteogenic-adipogenic differentiation-related factors in femoral tissue, including Runt-related transcription factor 2 (Runx2), bone morphogenetic protein 2 (BMP-2), peroxisome proliferator-activated receptor γ (PPARγ), chemerin and chemokine-like receptor 1 (CMKLR1). ResultsCompared with the blank group, the model group showed a significant increase in body mass, a significant decrease in the uterine index, BV/TV, Tb.N, Tb.Th and BMD, a significant increase in Tb.Sp, and serum IL-1β, IL-6, and TNF-α levels, a significant reduction of mRNA expression of Runx2 and BMP-2 in bone tissue, and a significant increased mRNA expression of PPARγ, chemerin, and CMKLR1 (P<0.01). HE staining revealed that the femoral tissue showed a reduction and sparsity of trabeculae, a significant enlargement of the medullary cavity, and a large number of fat cells. Compared to the model group, the low-dose, high-dose Zhimu-Huangbai groups, and estradiol group showed significant improvements in all the above-mentioned indicators (P<0.05 or P<0.01). HE staining revealed a significant increase in trabeculae, more organized arrangement, and a marked reduction in fat cells. Compared to low-dose Zhimu-Huangbai group, the high-dose Zhimu-Huangbai group exhibited a significant increase in the uterine index and BMD, and a significant reduction in body mass and PPARγ and Chemerin mRNA expression (P<0.05 or P<0.01). Compared to high-dose Zhimu-Huangbai group, the estradiol group showed a decrease in uterine index, BV/TV, Tb.N, Tb.Th, BMD, and BMP-2 mRNA expression, while the levels of IL-1β, TNF-α, and IL-6, as well as Tb.Sp and the mRNA expressions of PPARγ, chemerin, and CMKLR1 increased (P<0.05 or P<0.01). ConclusionThe Zhimu-Huangbai medicinal pair can alleviate PMOP bone loss, and its mechanism of action is related to reducing the levels of inflammatory factors, correcting the disorder of osteogenic-adipogenic differentiation of bone marrow mesenchymal stem cells (BMSCs), and promoting the differentiation of BMSCs into osteoblasts.

Objective:To explore the value of Plan-Do-Check-Act (PDCA) management model in improving the quality of breast ultrasound diagnosis.Methods:From January 1 to December 31, 2021, patients undergoing breast nodule surgery in the Union Hospital, Tongji Medical College, Huazhong University of Science and Technology were selected for breast ultrasound Breast Imaging Reporting and Data System (BI-RADS) classification diagnosis and follow-up. Using pathological results as the gold standard, the malignant rate of different BI-RADS grade and the coincidence rate of ultrasound diagnosis of breast cancer before the first treatment were analyzed. PDCA cycle management mode was introduced to analyze, learn and sort out the quality of breast ultrasound diagnosis. The same method was used to follow up the breast ultrasound diagnosis in the ultrasound department of our hospital from January 1 to December 31, 2022. The results of two follow-up visits were compared.Results:Compared with 2021, the malignancy rates of category 3 and 4a BI-RADS diagnosed by ultrasonic diagnosis of breast nodules in hospitals in 2022 were closer to the malignancy rates recommended by the classification guidelines of BI-RADS (all P<0.05). There was no significant difference in the malignant rate of BI RADS 4b, 4c and 5 types of nodules (all P>0.05). In 2022, compared with 2021, the ultrasound diagnosis coincidence rate before the first treatment of breast disease increased from 90.4%(1 592/1 761) to 95.9%(1 806/1 884). Conclusions:PDCA management mode is helpful to improve the classification and diagnosis quality of breast ultrasound BI-RADS, and better assist clinical diagnosis and treatment.

Objective:To evaluate the diagnostic efficacy and practicality of the Jaundice color card (JCard) as a screening tool for neonatal jaundice.Methods:Following the standards for reporting of diagnostic accuracy studies (STARD) statement, a multicenter prospective study was conducted in 9 hospitals in China from October 2019 to September 2021. A total of 845 newborns who were admitted to the hospital or outpatient department for liver function testing due to their own diseases. The inclusion criteria were a gestational age of ≥35 weeks, a birth weight of ≥2 000 g, and an age of ≤28 days. The neonate′s parents used the JCard to measure jaundice at the neonate′s cheek. Within 2 hours of the JCard measurement, transcutaneous bilirubin (TcB) was measured with a JH20-1B device and total serum bilirubin (TSB) was detected. The Pearson′s correlation analysis, Bland-Altman plots and the receiver operating characteristic (ROC) curve were used for statistic analysis.Results:Out of the 854 newborns, 445 were male and 409 were female; 46 were born at 35-36 weeks of gestational age and 808 were born at ≥37 weeks of gestational age. Additionally, 432 cases were aged 0-3 days, 236 cases were aged 4-7 days, and 186 cases were aged 8-28 days. The TSB level was (227.4±89.6) μmol/L, with a range of 23.7-717.0 μmol/L. The JCard level was (221.4±77.0) μmol/L and the TcB level was (252.5±76.0) μmol/L. Both the JCard and TcB values showed good correlation ( r=0.77 and 0.80, respectively) and agreements (96.0% (820/854) and 95.2% (813/854) of samples fell within the 95% limits of agreement, respectively) with TSB. The JCard value of 12 had a sensitivity of 0.93 and specificity of 0.75 for identifying a TSB ≥205.2?μmol/L, and a sensitivity of 1.00 and specificity of 0.35 for identifying a TSB ≥342.0?μmol/L. The TcB value of 205.2?μmol/L had a sensitivity of 0.97 and specificity of 0.60 for identifying TSB levels of 205.2 μmol/L, and a sensitivity of 1.00 and specificity of 0.26 for identifying TSB levels of 342.0 μmol/L. The areas under the ROC curve (AUC) of JCard for identifying TSB levels of 153.9, 205.2, 256.5, and 342.0 μmol/L were 0.96, 0.92, 0.83, and 0.83, respectively. The AUC of TcB were 0.94, 0.91, 0.86, and 0.87, respectively. There were both no significant differences between the AUC of JCard and TcB in identifying TSB levels of 153.9 and 205.2 μmol/L (both P>0.05). However, the AUC of JCard were both lower than those of TcB in identifying TSB levels of 256.5 and 342.0 μmol/L (both P<0.05). Conclusions:JCard can be used to classify different levels of bilirubin, but its diagnostic efficacy decreases with increasing bilirubin levels. When TSB level are ≤205.2 μmol/L, its diagnostic efficacy is equivalent to that of the JH20-1B. To prevent the misdiagnosis of severe jaundice, it is recommended that parents use a low JCard score, such as 12, to identify severe hyperbilirubinemia (TSB ≥342.0 μmol/L).

Extracellular polymeric substances(EPS)constitutes crucial elements within bacterial biofilms,facili-tating accelerated antimicrobial resistance and conferring defense against the host's immune cells.Developing precise and effective antibiofilm approaches and strategies,tailored to the specific charac-teristics of EPS composition,can offer valuable insights for the creation of novel antimicrobial drugs.This,in turn,holds the potential to mitigate the alarming issue of bacterial drug resistance.Current analysis of EPS compositions relies heavily on colorimetric approaches with a significant bias,which is likely due to the selection of a standard compound and the cross-interference of various EPS compounds.Considering the pivotal role of EPS in biofilm functionality,it is imperative for EPS research to delve deeper into the analysis of intricate compositions,moving beyond the current focus on polymeric materials.This ne-cessitates a shift from heavy reliance on colorimetric analytic methods to more comprehensive and nuanced analytical approaches.In this study,we have provided a comprehensive summary of existing analytical methods utilized in the characterization of EPS compositions.Additionally,novel strategies aimed at targeting EPS to enhance biofilm penetration were explored,with a specific focus on high-lighting the limitations associated with colorimetric methods.Furthermore,we have outlined the challenges faced in identifying additional components of EPS and propose a prospective research plan to address these challenges.This review has the potential to guide future researchers in the search for novel compounds capable of suppressing EPS,thereby inhibiting biofilm formation.This insight opens up a new avenue for exploration within this research domain.
