[Study on changes of Styrax varieties].

Styrax is a commonly used imported traditional Chinese medicinal material in China. It was introduced to China in the Han Dynasty and was first described as a traditional Chinese medicine in Miscellaneous Records of Famous Physicians(Ming Yi Bie Lu). In this paper, by combing ancient and modern Chinese and foreign herbal medicine books and modern literature, combined with the results of field investigations on the origin of Styrax, the changes of Styrax involving the name, quality evaluation, origin, place of origin, and harvesting and processing were systematically verified. The results show that since ancient times, the origin and place of origin of Styrax have been unclear. The medical scientists of all dynasties in China have evaluated the quality of Styrax from four aspects: texture, viscosity, odor concentration, and color. The varieties of Styrax changed twice. The first change may have occurred during the Sui and Tang Dynasties, and the base changed from Styrax officinalis to Liquidambar orientalis. The second change was in modern times, and the base changed from L. orientalis to L. styraciflua. At the same time, the place of origin changed for the first time, from Turkey, Syria, and other countries in southern Asia Minor to Honduras, Guatemala, and other countries in Central America and southern North America. This paper studied the historical evolution of Styrax in terms of quality evaluation, origin, place of origin, character, and harvesting and processing. At the same time, it summarized the application of Styrax in the western countries, which can provide a historical basis for the further development and utilization of Styrax.

The LiV3 O8 Superlattice Cathode with Optimized Zinc Ion Insertion Chemistry for High Mass-Loading Aqueous Zinc-Ion Batteries.

Resolving the sluggish transport kinetics of divalent Zn2+ in the cathode lattice and improving mass-loading performance are crucial for advancing the zinc-ion batteries (AZIBs) application. Herein, PEO-LiV3 O8 superlattice nanosheets (PEO-LVO) with expanded interlayer spacing (1.16 nm) are fabricated to provide a high-rate, stable lifetime, and large mass-loading cathode. The steady in-plane expansion without shrinkage after the first cycle, but reversible H+ /Zn2+ co-insertion in PEO-LVO are demonstrated by operando synchrotron X-ray diffraction and ex situ characterizations. Moreover, the large capacity of PEO-LVO is traced back to the optimized Zn2+ insertion chemistry with increased Zn2+ storage ratio, which is facilitated by the interlayer PEO in lowering the Zn2+ diffusion barrier and increased number of active sites from additional interfaces, as anticipated by density functional theory. Due to the optimized ion insertion resulting in stalled interfacial byproducts and rapid kinetics, PEO-LVO achieves excellent high mass-loading performance (areal capacity up to 6.18 mAh cm-2 for freestanding electrode with 24 mg cm-2 mass-loading and 2.8 mAh cm-2 at 130 mA cm-2 for conventional electrode with 27 mg cm-2 mass-loading). As a proof-of-concept, the flexible all-solid-state fiber-shaped AZIBs with high mass-loading woven into a fabric can power an electronic watch, highlighting the application potential of PEO-LVO cathode.

Single-Plane Retroperitoneoscopic Adrenalectomy Guided by Indocyanine Green Dye: An Optimized Step.

Background: The objective of this study was to explore the perioperative outcomes of single-plane posterior retroperitoneoscopic adrenalectomy (SPRA) guided by indocyanine green dye (ICG) fluorescence imaging. Methods: A retrospective analysis of patients who underwent SPRA from April to September 2023 in our center was conducted. Patients were divided into the ICG group and the non-ICG group, based on whether they received intraoperative ICG fluorescence guided or not. Baseline and perioperative data were recorded and analyzed by R software (R 4.3.1). Results: A total of 23 patients were enrolled in the study, with 12 in the ICG group and 11 in the non-ICG group. The demographics including age, gender, body mass index, or American Society of Anesthesiologists classification showed no significant differences between groups. There were obvious advantages in shortening adrenal gland localization time and total operative time, as well as reducing estimated blood loss in the ICG group compared with the non-ICG group (5.58 ± 0.36 minutes vs 7.55 ± 0.62 minutes, p < 0.001; 27.50 ± 5.46 minutes vs 45.00 ± 10.99 minutes, p < 0.001; 22.91 ± 7.57 mL vs 54.54 ± 18.90 mL, p < 0.001; respectively). Furthermore, patients in the ICG group exhibited significantly lower visual analog pain scale scores at 24 hours postoperatively and at discharge (p = 0.001 and p = 0.006, respectively). The oral intake intervals, hospital stays, and perioperative complications were comparable between groups. Conclusions: ICG-guided SPRA could be a safe and effective procedure for patients with adrenal tumors. This technique improves the accuracy and efficacy of adrenal gland localization and has shown benefits in perioperative outcomes. The use of ICG fluorescence guidance represents a promising clinical application.

Effect of Magnetic Field on Maskless Localized Electrodepositing Three-Dimensional Microstructure of Nano Nickel Crystals.

In the intricate process of maskless localized electrodeposition (MLED) for fabricating three-dimensional microstructures, specifically nickel micro-columns with an aspect ratio of 7:1, magnetic fields of defined strength were employed, oriented both parallel and anti-parallel to the electric field. The aim was to achieve nanocrystalline microstructures and elevated deposition rates. A detailed comparative analysis was conducted to examine the volumetric deposition rate, surface morphology, and grain size of the MLED nickel crystal 3D microstructures, both in the absence and presence of the two magnetic field directions, facilitated by a self-assembled experimental setup. The results indicate that the anti-parallel magnetic field significantly boosts the volumetric deposition rate to a notable 19,050.65 µm3/s and refines the grain size, achieving an average size of 24.82 nm. Conversely, the parallel magnetic field is found to enhance the surface morphology of the MLED nickel crystal 3D microstructure.

Bladder neck contracture following transurethral surgery of prostate: a retrospective single-center study.

PURPOSE: Bladder neck contracture (BNC) is a rare but intolerant complication after transurethral surgery of prostate. The present study aims to investigate the incidence and risk factors of BNC in patients diagnosed benign prostate hyperplasia (BPH) and following transurethral resection or enucleation of the prostate (TURP/TUEP). METHODS: This retrospective study included 1008 BPH individuals who underwent transurethral surgery of the prostate between January 2017 and January 2022. Patients' demographics, medical comorbidities, urologic characteristics, perioperative parameters, and the presence of BNC were documented. Univariate and multivariate analyses were conducted to identify the risk factors. RESULTS: A total of 2% (20/1008) BPH patients developed BNC postoperatively and the median occurring time was 5.8 months. Particularly, the incidences of BNC were 4.7% and 1.3% in patients underwent Bipolar-TURP and TUEP respectively. Preoperative urinary tract infection (UTI), elevated PSA, smaller prostate volume (PV), bladder diverticulum (BD), and B-TURP were significantly associated with BNC in the univariate analysis. Further multivariate logistic regression demonstrated preoperative UTI (OR 4.04, 95% CI 2.25 to 17.42, p < 0.001), BD (OR 7.40, 95% CI 1.83 to 31.66, p < 0.001), and B-TURP (OR 3.97, 95% CI 1.55 to 10.18, p = 0.004) as independent risk factors. All BNC patients were treated with transurethral incision of the bladder neck (TUIBN) combined with local multisite injection of betamethasone. During a median follow-up of 35.8 months, 35% (7/20) of BNC patients recurred at a median time of 1.8 months. CONCLUSION: BNC was a low-frequency complication following transurethral surgery of prostate. Preoperative UTI, BD, and B-TURP were likely independent risk factors of BNC. TUIBN combined with local multisite injection of betamethasone may be promising choice for BNC treatment.

[Textual research on Bungarus Parvus].

Bungarus Parvus, a precious animal Chinese medicinal material used in clinical practice, is believed to be first recorded in Ying Pian Xin Can published in 1936. This study was carried out to analyze the names, geographical distribution, morphological characteristics, ecological habits, poisonousness, and medicinal parts by consulting ancient Chinese medical books and local chronicles, Chinese Pharmacopeia, different processing standards of trditional Chinese medicine(TCM) decoction pieces, and modern literatures. The results showed that the earliest medicinal record of Bungarus Parvus was traced to 1894. In 1930, this medicinal material was used in the formulation of Annao Pills. The original animal, Bungarus multicinctus, was recorded by the name of "Bojijia" in 1521. The morphological characteristics, ecological habits, and poisonousness of the original animal are the same in ancient and modern records. The geographical distribution is similar between the ancient records and modern documents such as China Medicinal Animal Fauna. The dried body of young B. multicinctus is used as Bungarus Parvus, which lack detailed references. As a matter of fact, it is still inconclusive whether there are differences between young snakes and adult snakes in terms of active ingredients, pharmacological effects, and clinical applications. This study clarified the medicinal history and present situation of Bungarus Parvus. On the basis of the results, it is suggested that systematic comparison on young and adult B. multicinctus should be carried out to provide references for revising the medicinal parts of B. multicinctus.

Clinical analysis of 114 cases of bronchiolitis in infants.

BACKGROUND: Bronchiolitis is a common lower respiratory tract infection in infants and young children. Severe cases may be accompanied by obvious dyspnea and oxygen saturation decline. AIM: To summarize the clinical features, standard diagnosis, and treatment of bronchiolitis. METHODS: This is a retrospective analysis of 114 pediatric patients (74 males, 40 females) who were first diagnosed as having bronchioles at the Department of Pediatrics of Tongling Maternal and Child Health Hospital from January 2019 to December 2019. The clinical features, imaging features, treatment, and other clinical data were recorded and analyzed. RESULTS: The age of onset of the disease was mainly from 1 mo to 6 mo (75.4%), and the time to hospital visit was mostly from the 2nd day to the 4th day of the course of the disease (75.4%). Lung imaging examination showed increase in lung texture, fuzzy (93.8%). The main treatment was atomization therapy: Budesonide combined with terbutaline (45.6%) and budesonide combined with salbutamol (38.5%). The average hospitalization time was 7.1 ± 2.4 d, and the overall cure rate was 94.7%. In patients without bacterial infection, the use of antibiotics significantly prolonged the length of hospital stay (7.8 ± 2.5 d vs 5.7 ± 1.8 d) and improved the cure rate (98.3% vs 87.9%, P < 0.05). CONCLUSION: Infants with bronchiolitis are mainly male and tend to have a good prognosis. However, the unneeded use of antibiotics may prolong the length of hospital stay significantly, which imposes the burden both on the patients and hospital system.

c-Jun as a one-way valve at the naive to primed interface.

BACKGROUND: c-Jun is a proto-oncogene functioning as a transcription factor to activate gene expression under many physiological and pathological conditions, particularly in somatic cells. However, its role in early embryonic development remains unknown. RESULTS: Here, we show that c-Jun acts as a one-way valve to preserve the primed state and impair reversion to the naïve state. c-Jun is induced during the naive to primed transition, and it works to stabilize the chromatin structure and inhibit the reverse transition. Loss of c-Jun has surprisingly little effect on the naïve to primed transition, and no phenotypic effect on primed cells, however, in primed cells the loss of c-Jun leads to a failure to correctly close naïve-specific enhancers. When the primed cells are induced to reprogram to a naïve state, these enhancers are more rapidly activated when c-Jun is lost or impaired, and the conversion is more efficient. CONCLUSIONS: The results of this study indicate that c-Jun can function as a chromatin stabilizer in primed EpiSCs, to maintain the epigenetic cell type state and act as a one-way valve for cell fate conversions.

Cation Defect-Engineered Boost Fast Kinetics of Two-Dimensional Topological Bi2 Se3 Cathode for High-Performance Aqueous Zn-Ion Batteries.

The challenge with aqueous zinc-ion batteries (ZIBs) lies in finding suitable cathode materials that can provide high capacity and fast kinetics. Herein, two-dimensional topological Bi2 Se3 with acceptable Bi-vacancies for ZIBs cathode (Cu-Bi2-x Se3 ) is constructed through one-step hydrothermal process accompanied by Cu heteroatom introduction. The cation-deficient Cu-Bi2-x Se3 nanosheets (≈4 nm) bring improved conductivity from large surface topological metal states contribution and enhanced bulk conductivity. Besides, the increased adsorption energy and reduced Zn2+ migration barrier demonstrated by density-functional theory (DFT) calculations illustrate the decreased Coulombic ion-lattice repulsion of Cu-Bi2-x Se3 . Therefore, Cu-Bi2-x Se3 exhibits both enhanced ion and electron transport capability, leading to more carrier reversible insertion proved by in situ synchrotron X-ray diffraction (SXRD). These features endow Cu-Bi2-x Se3 with sufficient specific capacity (320 mA h g-1 at 0.1 A g-1 ), high-rate performance (97 mA h g-1 at 10 A g-1 ), and reliable cycling stability (70 mA h g-1 at 10 A g-1 after 4000 cycles). Furthermore, quasi-solid-state fiber-shaped ZIBs employing the Cu-Bi2-x Se3 cathode demonstrate respectable performance and superior flexibility even under high mass loading. This work implements a conceptually innovative strategy represented by cation defect design in topological insulator cathode for achieving high-performance battery electrochemistry.

DCX-EMAP is a core organizer for the ultrastructure of Drosophila mechanosensory organelles.

Mechanoreceptor cells develop specialized mechanosensory organelles (MOs), where force-sensitive channels and supporting structures are organized in an orderly manner to detect forces. It is intriguing how MOs are formed. Here, we address this issue by studying the MOs of fly ciliated mechanoreceptors. We show that the main structure of the MOs is a compound cytoskeleton formed of short microtubules and electron-dense materials (EDMs). In a knock-out mutant of DCX-EMAP, this cytoskeleton is nearly absent, suggesting that DCX-EMAP is required for the formation of the MOs and in turn fly mechanotransduction. Further analysis reveals that DCX-EMAP expresses in fly ciliated mechanoreceptors and localizes to the MOs. Moreover, it plays dual roles by promoting the assembly/stabilization of the microtubules and the accumulation of the EDMs in the MOs. Therefore, DCX-EMAP serves as a core ultrastructural organizer of the MOs, and this finding provides novel molecular insights as to how fly MOs are formed.

FaceScape: 3D Facial Dataset and Benchmark for Single-View 3D Face Reconstruction.

In this article, we present a large-scale detailed 3D face dataset, FaceScape, and the corresponding benchmark to evaluate single-view facial 3D reconstruction. By training on FaceScape data, a novel algorithm is proposed to predict elaborate riggable 3D face models from a single image input. FaceScape dataset releases 16,940 textured 3D faces, captured from 847 subjects and each with 20 specific expressions. The 3D models contain the pore-level facial geometry that is also processed to be topologically uniform. These fine 3D facial models can be represented as a 3D morphable model for coarse shapes and displacement maps for detailed geometry. Taking advantage of the large-scale and high-accuracy dataset, a novel algorithm is further proposed to learn the expression-specific dynamic details using a deep neural network. The learned relationship serves as the foundation of our 3D face prediction system from a single image input. Different from most previous methods, our predicted 3D models are riggable with highly detailed geometry under different expressions. We also use FaceScape data to generate the in-the-wild and in-the-lab benchmark to evaluate recent methods of single-view face reconstruction. The accuracy is reported and analyzed on the dimensions of camera pose and focal length, which provides a faithful and comprehensive evaluation and reveals new challenges. The unprecedented dataset, benchmark, and code have been released to the public for research purpose.

Identifying a distinct fibrosis subset of NAFLD via molecular profiling and the involvement of profibrotic macrophages.

BACKGROUND: There are emerging studies suggesting that non-alcoholic fatty liver disease (NAFLD) is a heterogeneous disease with multiple etiologies and molecular phenotypes. Fibrosis is the key process in NAFLD progression. In this study, we aimed to explore molecular phenotypes of NAFLD with a particular focus on the fibrosis phenotype and also aimed to explore the changes of macrophage subsets in the fibrosis subset of NAFLD. METHODS: To assess the transcriptomic alterations of key factors in NAFLD and fibrosis progression, we included 14 different transcriptomic datasets of liver tissues. In addition, two single-cell RNA sequencing (scRNA-seq) datasets were included to construct transcriptomic signatures that could represent specific cells. To explore the molecular subsets of fibrosis in NAFLD based on the transcriptomic features, we used a high-quality RNA-sequencing (RNA-seq) dataset of liver tissues from patients with NAFLD. Non-negative matrix factorization (NMF) was used to analyze the molecular subsets of NAFLD based on the gene set variation analysis (GSVA) enrichment scores of key molecule features in liver tissues. RESULTS: The key transcriptomic signatures on NAFLD including non-alcoholic steatohepatitis (NASH) signature, fibrosis signature, non-alcoholic fatty liver (NAFL) signature, liver aging signature and TGF-ß signature were constructed by liver transcriptome datasets. We analyzed two liver scRNA-seq datasets and constructed cell type-specific transcriptomic signatures based on the genes that were highly expressed in each cell subset. We analyzed the molecular subsets of NAFLD by NMF and categorized four main subsets of NAFLD. Cluster 4 subset is mainly characterized by liver fibrosis. Patients with Cluster 4 subset have more advanced liver fibrosis than patients with other subsets, or may have a high risk of liver fibrosis progression. Furthermore, we identified two key monocyte-macrophage subsets which were both significantly correlated with the progression of liver fibrosis in NAFLD patients. CONCLUSION: Our study revealed the molecular subtypes of NAFLD by integrating key information from transcriptomic expression profiling and liver microenvironment, and identified a novel and distinct fibrosis subset of NAFLD. The fibrosis subset is significantly correlated with the profibrotic macrophages and M2 macrophage subset. These two liver macrophage subsets may be important players in the progression of liver fibrosis of NAFLD patients.

Broad phosphorylation mediated by testis-specific serine/threonine kinases contributes to spermiogenesis and male fertility.

Genetic studies elucidate a link between testis-specific serine/threonine kinases (TSSKs) and male infertility in mammals, but the underlying mechanisms are unclear. Here, we identify a TSSK homolog in Drosophila, CG14305 (termed dTSSK), whose mutation impairs the histone-to-protamine transition during spermiogenesis and causes multiple phenotypic defects in nuclear shaping, DNA condensation, and flagellar organization in spermatids. Genetic analysis demonstrates that kinase catalytic activity of dTSSK, which is functionally conserved with human TSSKs, is essential for male fertility. Phosphoproteomics identify 828 phosphopeptides/449 proteins as potential substrates of dTSSK enriched primarily in microtubule-based processes, flagellar organization and mobility, and spermatid differentiation and development, suggesting that dTSSK phosphorylates various proteins to orchestrate postmeiotic spermiogenesis. Among them, the two substrates, protamine-like protein Mst77F/Ser9 and transition protein Mst33A/Ser237, are biochemically validated to be phosphorylated by dTSSK in vitro, and are genetically demonstrated to be involved in spermiogenesis in vivo. Collectively, our findings demonstrate that broad phosphorylation mediated by TSSKs plays an indispensable role in spermiogenesis.

Primary seminal vesicle Burkitt lymphoma in a patient living with HIV undergoing radical prostate and seminal vesicle resection: a rare missed case report.

Primary seminal vesicle Burkitt lymphoma (PSBL) is rare that is not frequently reported. Burkitt lymphoma is often associated with extranodal organs. The diagnosis of carcinoma in seminal vesical can be difficult. In this report, we present a missed case of PSBL in a male patient who underwent radical prostate and seminal vesicle resection. We retrospectively analyzed the clinical data to explore the diagnosis, pathological features, treatment, and prognosis of this rare disease. The patient visited our hospital for dysuria, and the serum prostate-specific antigen (PSA) was moderately elevated. Pelvic magnetic resonance imaging (MRI) and computed tomography (CT) scans suggested a notable enlargement of the seminal vesicle. The patient then underwent radical surgery and the pathology diagnosis revealed Burkitt lymphoma. The diagnosis of PSBL is difficult, and the prognosis is generally poorer than that of other types of lymphoma. However, earlier diagnosis and treatment may help to improve the survival rate among patients with Burkitt lymphoma.

Camrelizumab as adjuvant therapy in urothelial carcinomas after radical surgery in people living with HIV.

BACKGROUND: Immune checkpoint inhibitors (ICIs) are effective strategies for multiple cancers and may be safe in people living with HIV (PLWH). Camrelizumab is a monoclonal antibody against PD-1 activating T cells against tumor cells. Evidence of camrelizumab's safety and activity in PLWH with urothelial carcinoma (UC) is lacking. Here, findings in a cohort of people living with HIV with advanced or metastatic urothelial carcinoma are presented. METHODS: Patients who had locally advanced or metastatic disease after radical surgery were given camrelizumab (200 mg intravenously every 3 weeks). The primary endpoint was objective response per Response Evaluation Criteria in Solid Tumors version 1.1. The second endpoint was adverse events after treatment. RESULTS: In total, nine patients were included in this study with a median follow-up of 6.2 months (4.1-20.5). The objective response rate achieved 55%. Tumor response comprised 2 (22%) complete responses and 3 (33%) partial responses. The median of progression-free survival was 6.2 months (95% CI, 9.83-20.63). Only two grade 3 adverse reactions were reported (no toxic deaths or immune-related deaths). CONCLUSION: Camrelizumab showed potent antitumor activity and acceptable safety in PLWH with advanced or metastatic urothelial carcinoma.

[Slicing specifications in general rule of processing in Chinese Pharmacopoeia from slicing development of Chinese materia medica processed product and thinking and suggestion on slicing techniques].

Slicing is critical in the processing of Chinese materia medica(CMM) processed product and the specification(thickness) is closely related to the quality of the decoction. On the basis of clarifying the concept and evolution of slicing of CMM processed product by reviewing the Chinese herbal classics of the past dynasties and general rules of local processing standards, this study discussed the development history of slicing specifications in general rules of Chinese Pharmacopoeia(2020 edition), analyzed the current situation and key problems, and proposed the thinking and suggestion on promoting the sound development of slicing of CMM processed product. Since 2000, the slicing thickness of CMM processed product in the general rules of local CMM processed product processing specifications newly revised and issued by 27 provinces, autonomous regions, and municipalities has been consistent with that in the general rules of the Chinese Pharmacopoeia(2020 edition). The standard that the thickness of extremely thin pieces is less than 0.5 mm is rarely retained, and the pieces in 0.5-1 mm thickness have not been found on the market, which is consistent with the provisions of the general rules of the Chinese Pharmacopoeia. This study can provide a historical and modern basis for the rationality of slicing of CMM processed product.

Camrelizumab for cancers in patients living with HIV: one-single center experience.

OBJECTIVES: The primary objective was to evaluate the safety of the anti-PD-1 antibody camrelizumab in people living with HIV (PLWH); the secondary objective was to evaluate tumor response. METHODS: From May 8, 2018, to December 10, 2021, twenty-four patients with HIV and advanced cancer as well as a CD4+ T-cell count greater than or equal to 100 cells/µL were treated with camrelizumab in daily practice. We describe the demographic characteristics, safety, and clinical course of these 24 PLWH with cancer treated with camrelizumab. Safety was assessed using the current Common Terminology Criteria for Adverse Events (CTCAE). The tumor response was assessed according to the Response Evaluation Criteria in Solid Tumors, version 1.1 (RECIST 1.1). RESULTS: The median number of cycles was 8 (4-26). Only two grade 3 adverse reactions were reported (no toxic deaths or immune-related deaths). Among the 24 patients, 2 (8%) complete responses and 6 (25%) partial responses were observed. 7 patients (29%) were at stable tumor status and others progressed. CONCLUSIONS: Data from the present study strongly support the use of camrelizumab (monoclonal antibodies targeting the PD-1 pathway) in this population, as it appears to be a feasible approach with no deleterious effects on PLWH and tolerability and acceptable efficacy. In addition, these findings further support the inclusion of PLWH with cancer in clinical trials evaluating the safety and efficacy of ICIs on cancer.

The Efficacy and Safety of Tislelizumab as Adjuvant Treatment for Advanced or Metastatic Bladder Cancer in People Living With HIV: A Retrospective Multi-Center Study.

BACKGROUND: People living with HIV (PLWH) have a worse prognosis than the general population. Locally advanced or metastatic bladder cancer (BCa) in PLWH has gradually been increasing in recent years. Immune checkpoint inhibitors can improve antitumor activity in the general population, but relevant data in PLWH are unknown. We thus evaluated the efficacy and safety of tislelizumab in PLWH with locally advanced or metastatic BCa. METHODS: This retrospective study included 24 patients with locally advanced or metastatic BCa, both HIV positive or negative who underwent tislelizumab treatment (200 mg i.v. every 3 weeks, Q3W) from the multi-centers between December 2019 and March 2022. Demographic details, clinical data, and cancer status were collected. The overall survival (OS), progression-free survival (PFS), overall response rate (ORR), disease control rate (DCR), clinical benefit rate (CBR), and treatment-related adverse events (TRAEs) were recorded and evaluated. RESULTS: A total of 24 individuals were chosen for this study, 10 had HIV and the other 14 did not. The median OS in the HIV-negative group was 62.3 (95% CI, 52.6 to 72.2) was no longer than that of the PLWH group 41.9 (95% CI, 32.9 to 51.0) weeks (HR .7, [95% CI, .17 to 3.30], P = .70). Furthermore, the median PFS in the HIV-negative group was 50.0 (95% CI, 36.2 to 63.9) was also no longer than that of the PLWH group 35.9 (95% CI, 25.5 to 46.3) (HR, 1.34, [95% CI, .38 to 4.69], P = .63). Of 24 patients, treatment-related adverse events, grade 3 or 4 occurred in 2 in the PLWH group and 3 in the HIV-negative group. CONCLUSION: This retrospective multi-center study suggested that tislelizumab may provide encouraging antitumor activity and could be generally well tolerated. In this retrospective analysis of patients with locally advanced or metastatic BCa, it seems that PLWH may have similar overall and progression-free survival compared to HIV-negative cases.

Quantitative and qualitative analysis of Artemisiae Verlotori Folium and Artemisiae Argyi Folium by high-performance liquid chromatography coupled with quadrupole-time-of-flight mass spectrometry.

Artemisiae Argyi Folium (Aiye in Chinese) has been widely used since ancient times. In the Lingnan region (Southern China), the leaf of Artemisia verlotorum Lamotte, which is named Hongjiaoai (HJA) because the roots are red (Hongjiao means red foot in Chinese), has been used as a local substitute for Artemisiae Argyi Folium. The plant has a long medicinal and edible history that can be traced to the Jin Dynasty. However, there is no systematic and reliable method to control the quality of Artemisiae Verlotori Folium. In this study, a comprehensive method involving high-performance liquid chromatography coupled with diode array detection and quadrupole-time-of-flight high-definition mass spectrometry was established to identify and quantify eight constituents (including organic acids and flavonoids) in Artemisiae Verlotori Folium and Artemisiae Argyi Folium as well as high-performance liquid chromatography fingerprints of the two varieties. Moreover, dissimilarities of chemical compositions among the two varieties were further investigated by orthogonal partial least squares discrimination analysis and cluster analysis. This research not only explored the similarities and differences between Artemisiae Verlotori Folium and Artemisiae Argyi Folium in eight components but also provided a qualitative and quantitative analytical method that quickly, accurately, and comprehensively assesses the quality of Artemisiae Verlotori Folium.
