Pinelliae Rhizoma (PR), known as Banxia in Chinese, Hange in Japanese, and Banha in Korean, is a renowned herbal medicine in East Asia derived from the dry tuber of Pinellia ternata (Thunb.) Breit. (PT). It is extensively utilized in dispensing granules, classical prescriptions, and herbal formulas to treat various conditions, including cough, infection, phlegm, nausea, asthma, and inflammation. Despite numerous studies on PR and its classical prescriptions over recent decades, a comprehensive synthesis of available evidence regarding its multifunctional roles and therapeutic potential is lacking. This review aims to address this gap by examining emerging evidence from metabonomics, preclinical studies, and clinical trials, while exploring potential trends and prospects for future research. A systematic literature search was conducted across six electronic databases, including PubMed, Web of Science, Scopus, ScienceDirect, Wanfang, and China National Knowledge Infrastructure, to identify relevant articles on PR published until March 2023. PR contains 107 compounds with diverse pharmacological activities, including anti-inflammatory, immune regulatory, anti-viral, anti-cancer, anti-asthma, antitussive and expectorant, antioxidant, anti-obesity, anti-atherosclerosis, anti-microbial, emetic and anti-emetic, anti-convulsant and anti-epileptic, sedative and hypnotic, learning and memory enhancement, and anti-depressant effects. Metabonomic studies suggest that raw PR may exhibit cardiotoxicity and pregnancy toxicity while showing no apparent hepatorenal toxicity. However, limited pharmacokinetic investigations on PR constrain its clinical translation. Furthermore, clinical safety data on PR is scarce, with only four clinical trials assessing its positive effects in pediatric epilepsy, nausea and vomiting, soft tissue injury, and chronic sinus tract. This review aims to enhance understanding of PR and provide valuable information and recommendations for further research and development of herbal medicine.

Objective To observe the value of augmented reality(AR)navigation system for assisting CT-guided puncture of pulmonary nodules in dog models.Methods Five healthy dogs were selected,and 4 target lung rings were implanted in each dog to build pulmonary nodule models.Deferring to crossover design,CT-guided punctures were performed with or without AR navigation 2 and 4 weeks after successful modeling,respectively,while punctures with AR navigation were regarded as AR group and the others as conventional group,respectively.The time duration of puncturing,the times of CT scanning,of needle adjustment,and the deviation distance between needle pinpoint to the center of pulmonary nodule shown on three-dimensional reconstruction were compared between groups.Results The duration time of puncture in AR group and conventional group was(13.62±5.11)min and(20.16±4.76)min,respectively.In AR group,the times of CT scanning,of needle adjustment,and the deviation distance was 2.40±0.50,2.75±0.44 and(2.94±1.92)mm,respectively,while in conventional group was 3.10±0.64,3.70±0.57 and(4.90±3.38)mm,respectively.The introduction of AR navigation was helpful to shortening the duration of puncture,reducing times of CT scanning and needle adjustment,also decreasing positioning error of needle pinpoint(all P＜0.05).In contrast,the variance of puncture sequences and dogs had no obvious effect on the results(both P＞0.05).Conclusion AR navigation system could improve accuracy and efficiency in CT-guided puncture of pulmonary nodules in dog models.

Objective To evaluate the application value of percutaneous angle positioning system based on augmented reality in improving the accuracy of liver puncture.Methods A canine liver with an embedded marking ring was used as the target for puncture.A skilled physician with over 5 years of experience in liver puncture and a novice physician with limited experience in liver puncture separately performed liver puncture using either the augmented reality-based percutaneous angle localization system(navigation)or CT-guided technique alone(non-navigation).The corresponding puncturing data of non-navigation skilled group(Group A),non-navigation non-skilled group(Group B),navigation skilled group(Group C),and navigation non-skilled group(Group D)were obtained.The differences in the evaluation indicators,including the number of CT scans,number of needle adjustment,time spent for operation,and distance of error,between Group A and Group B,between Group C and Group D,between Group A and Group C,and between Group B and Group D,were analyzed.Results Statistically significant differences in the number of CT scans,number of needle adjustment,time spent for operation,and distance of error existed between Group A and Group B,between Group A and Group C,and between Group B and Group D(all P＜0.0 5),while the differences in the number of CT scans,number of needle adjustment,time spent for operation,and distance of error between Group C and Group D were not statistically significant(all P＞0.05)Conclusion In performing liver puncture,the use of percutaneous angle localization system can reduce the number of CT scans,number of needle adjustment,time spent for operation and distance of error,and improve the puncture accuracy as well,which provides a basis for the clinical utilization of this system and the employment of this system-guided puncture technology in primary hospitals.(J Intervent Radiol,2024,33:507-511)

Objective To investigate the metabolic outcomes of primary aldosteronism(PA)patients receiving adrenalectomy(ADX)or spironolactone treatment and the contributing factors to the metabolic outcomes.Methods The clinical data of 70 patients with aldosterone-producing adenoma(APA)and 86 patients with idiopathic hyperaldosteronism(IHA)were retrospectively analyzed.All subjects received confirmatory diagnosis of APA or IHA at the Department of Endocrinology and Metabolism,West China Hospital between March 2018 and October 2020.APA patients underwent ADX,while IHA patients were given spironolactone,a mineralocorticoid receptor antagonist(MRA).After ADX or spironolactone treatment,the outcomes of the metabolic indicators and the inter-group differences between the APA patients and IHA patients were studied.Results There was no significant difference between the baseline data of the APA group and those of the IHA group in terms of age,sex,duration of hypertension,maximum systolic blood pressure(SBP-max),maximum diastolic blood pressure(DBP-max),body mass index(BMI),fasting blood glucose(FBG),lipid parameters,and renal function.IHA patients had higher waist circumference,serum potassium,and plasma renin activity(PRA)than those of the APA patients(all P＜0.05).All patients showed significant improvement in blood pressure,blood potassium,and plasma aldosterone at follow-up.However,they also showed increased triglycerides(TG)accompanied by deterioration in renal function(P≤0.001).Multiple regression showed that TG levels were associated with spironolactone treatment for IHA patients and post-treatment BMI and creatinine levels.Furthermore,APA patients showed improvement in their FBG after ADX(P=0.041),while IHA patients showed elevated levels of FBG after spironolactone treatment(P=0.037).Conclusion After treatment,PA patients still may experience abnormal lipid metabolism and deteriorating renal function.Spironolactone therapy may give rise to worse glucolipid metabolism than ADX therapy does.
