Two novel skeleton sesquiterpenoids (1 and 6), along with four new iphionane-type sesquiterpenes (2-5) and six new cyperane-type sesquiterpenes (7-11), were isolated from the whole plant of Artemisia hedinii (A. hedinii). The two novel skeleton compounds (1 and 6) were derived from the decarbonization of iphionane and cyperane-type sesquiterpenes, respectively. Their structures were elucidated through a comprehensive analysis of spectroscopic data, including high-resolution electrospray ionization mass spectrometry (HR-ESI-MS) and 1D and 2D nuclear magnetic resonance (NMR) spectra. The absolute configurations were determined using electronic circular dichroism (ECD) spectra, single-crystal X-ray crystallographic analyses, time-dependent density functional theory (TDDFT) ECD calculation, density functional theory (DFT) NMR calculations, and biomimetic syntheses. The biomimetic syntheses of the two novel skeletons (1 and 6) were inspired by potential biogenetic pathways, utilizing a predominant eudesmane-type sesquiterpene (A) in A. hedinii as the substrate. All compounds were evaluated in LX-2 cells for their anti-hepatic fibrosis activity. Compounds 2, 8, and 10 exhibited significant activity in downregulating the expression of α-smooth muscle actin (α-SMA), a protein involved in hepatic fibrosis.

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.

Acute respiratory infection caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) had caused a global pandemic since 2019, and posed a serious threat to global health security. Traditional Chinese medicine (TCM) has played an indispensable role in the battle against the epidemic. Many components originated from TCMs were found to inhibit the production of SARS-CoV-2 3C-like protease (3CLpro) and papain-like protease (PLpro), which are two promising therapeutic targets to inhibit SARS-CoV-2. This study describes a systematic investigation of the roots and rhizomes of Sophora tonkinensis, which results in the characterization of 12 new flavonoids, including seven prenylated flavanones (1-7), one prenylated flavonol (8), two prenylated chalcones (9-10), one isoflavanone (11), and one isoflavan dimer (12), together with 43 known compounds (13-55). Their structures including the absolute configurations were elucidated by comprehensive analysis of MS, 1D and 2D NMR data, and time-dependent density functional theory electronic circular dichroism (TDDFT ECD) calculations. Compounds 12 and 51 exhibited inhibitory effects against SARS-CoV-2 3CLpro with IC₅₀ values of 34.89 and 19.88 μmol·L^-1, repectively while compounds 9, 43 and 47 exhibited inhibitory effects against PLpro with IC₅₀ values of 32.67, 79.38, and 16.74 μmol·L^-1, respectively.

We reported a clinical caseof gas gangrene in the lower back and buttocks due to local intramuscular injection. A 43-year-old male was treated by local private clinic for low back pain. He underwent local intramuscular injection in his lower back and buttocks. 5 or 6 hours after the treatment,he felt worsen of low back pain (VAS 5 points)with a fever. After one day of treatment, the lower back pain was even worse(VAS 8 points). And he had soy-sauce urine and a high fever. The results of laboratory examination and clinical manifestation suggested multiple organ failure within a short period of time. Imaging (CT) suggested large area of gas and muscle necrosis in the lower back and buttocks. Considering the progress of the disease, emergency surgery on lumbar back and right buttocks was performed after hospitalization. Rapid bacterial smear reported gram-positive coarse bacteria. Anaerobic culture suggested clostridium perfringens. Aerobic culture result did not show any bacterial growth. According to the clinical manifestation, imaging (CT), intraoperative judgment and postoperative anaerobic culture results, the clinical diagnosis was gas gangrene. Gas gangrene is a special infectious disease in clinic, which can be characterized by low morbidity, difficult early diagnosis,rapid disease progression and high mortality. Sinceintramuscular injection leaded to this disease in our case, the importance of standardized aseptic procedures should be emphasized.

Traditional Chinese Medicine (TCM) is an important reservoir for bioactive natural products. TCM extraction methods by water decoction and wine tincture are an integral part of TCM and essential for their widely acknowledged efficacy. In this study, we selected 6 common TCMs that are rich in chemistry to investigate whether the TCM extraction methods deliver molecules with drug-like physical chemical properties. Six TCM herbal materials were extracted by water, 95% ethanol, and sequential hexane, dichloromethane and methanol. The extracts were analyzed by HPLC and H NMR. Isolation on one of the extracts yielded 32 compounds, their physical chemical properties were analyzed by Instant JChem. Our results showed that ethanol extraction, which mimics TCM wine tincture, delivered compounds with physical chemical properties compliant to Lipinski's rule of 5.

Gastric cancer (GC) is a highly heterogenic disease, and it is the second leading cause of cancer death in the world. Common chemotherapies are not very effective for GC, which often presents as an advanced or metastatic disease at diagnosis. Treatment options are limited, and the prognosis for advanced GCs is poor. The landscape of genomic alterations in GCs has recently been characterized by several international cancer genome programs, including stud-ies that focused exclusively on GCs in Asians. These studies identiifed major recurrent driver mutations and provided new insights into the mutational heterogeneity and genetic proifles of GCs. An analysis of gene expression data by the Asian Cancer Research Group (ACRG) further uncovered four distinct molecular subtypes with well-deifned clini-cal features and their intersections with actionable genetic alterations to which targeted therapeutic agents are either already available or under clinical development. In this article, we review the ACRG GC project. We also discuss the implications of the genetic and molecular ifndings from various GC genomic studies with respect to developing more precise diagnoses and treatment approaches for GCs.
