Visualized Clinical-Radiomics Model Based on Non-Contrast Computed Tomography for Predicting Efficacy of Surufatinib in Hepatic Metastases of Neuroendocrine Neoplasms
1 Introduction Neuroendocrine neoplasms (NENs) are a heterogeneous group of tumors originating from neuroendocrine cells, characteristically differentiated and expressing neuroendocrine markers [1]. In recent years, the clinical detection rate of NENs has increased significantly with the advancement of diagnostic imaging technology and the popularity of health check-ups [2].

3.2. Synthesis and Characterization of AEMs Figure 2 illustrates the synthesis process of the CQAPSU membrane. The process involved the reaction of synthesized VBN with CMPSU, followed by thermal polymerization at 80 °C to yield the cross-linked CQAPSU membrane. Owing to its highly dense cross-linked structure, the membrane exhibited insolubility in common deuterated solvents, precluding 1 H NMR analysis.
A blood-biomarker based CTC-ALRI score predicts recurrence in hepatocellular carcinoma patients following curative resection
Abstract Background: Hepatocellular carcinoma (HCC) recurrence after curative resection remains a critical challenge that significantly compromises long-term survival. This study aimed to develop a novel blood-based prognostic scoring system integrating circulating tumor cells (CTCs) and aspartate aminotransferase-to-lymphocyte ratio index (ALRI) for predicting postoperative HCC recurrence.
Magnetic NaA Zeolites Synthesized from Dual Solid Wastes Enables Selective Efficient Recovery of Rare Earth Ions from Neodymium Iron Boron Electroplating Wastewater
Abstract Click to copy section linkSection link copied! This research leverages the minor iron oxides and carbon contained in Bayan Obo tailings (BOT) and coal gangue for the synthesis of magnetic zeolite NaA, which was subsequently applied to recover and separate rare earth elements (REEs) from Nd–Fe–B passivation solutions.
CNIPA updates patent examination guidelines to address emerging technology, regulate dual filing and invalidations
On 13 November 2025, the China National IP Administration (CNIPA) enacted the amendment to the Patent Examination Guidelines, which will become effective on 1 January 2026.
Quality of guidelines for hyperthyroidism: systematic quality assessment using the AGREE II tool
ABSTRACT Objectives The aim of this study was to systematically assess the quality of different guidelines for the management of patients with hyperthyroidism and to explore and analyze the recommendations and key evidence in different guidelines. Methods A systematic search of databases and websites was conducted to identify treatment guidelines for hyperthyroidism.
Molecular typing and mutational characterization of rectal neuroendocrine neoplasms
1 INTRODUCTION Neuroendocrine neoplasms (NENs), which have seen a rapid increase in incidence in recent years, can occur in whole-body organs and tissues. According to the 2019 World Health Organization (WHO) classification of endocrine and neuroendocrine tumors (NETs), NENs are classified as well-differentiated NETs, poorly differentiated neuroendocrine carcinomas (NECs) and mixed neuroendocrine-non-neuroendocrine neoplasms (MiNENs).

CNIPA measures are a big step forward for patent pledges in China
The China National Intellectual Property Administration (CNIPA) released amended Measures for Registration of Pledge on Patent Rights on 15 November 2021 – these are designed to streamline the patent pledge procedure and provide greater clarity in practice. The measures were published in response to China’s State Council promulgation of the Fourteenth Five-Year Plan for the Protection and Utilisation of IP Rights, on 28 October 2021.
CNIPA clamps down on ‘abnormal’ application practices in fresh drive for patent quality
Co-published Xiaoling Duan The China National IP Administration (CNIPA) has released official statistics, which show that the total number of patent applications for inventions, utility models and designs filed in China is increasing against the backdrop of the covid-19 pandemic. The colossal volume of patent applications filed by domestic applicants and the mixed quality of applied-for patents have long been criticised by domestic and international stakeholders.
Everything you need to know about China’s new Patent Law
Co-published Xiaoling Duan On 17 October 2020 China’s top legislature, the National People’s Congress, passed the fourth round of amendments to the Patent Law, which will come into effect on 1 June 2021. It has been eight years since the first draft was released to solicit public opinions. This latest set of changes updates China’s patent regime in the following ways.
CNIPA’s latest patent practice and 2020 patent objectives
Co-published Xiaoling Duan China’s National Intellectual Property Administration (CNIPA) has published its statistics for the first two quarters of 2020. These indicate that the numbers of patent applications for inventions, utility models and designs for the first quarter were 328,412 (down 3.6% year on year), 563,657 (up 12.1%) and 131,135 (down 16.6%) respectively.
China: Analysing trends in biotechnology patent prosecution in China
Patentability of human embryonic stem cells The amended Patent Examination Guidelines, which China National Intellectual Property Administration (CNIPA) has been implementing since November 1 2019, have brought significant changes to the utilisation of human embryonic stem cells.
