Objective To elucidate the changes in the gut microbiota and molecular mechanism of huaier in enhancing the efficacy of oxaliplatin (OXA) chemotherapy in gastric cancer (GC). Methods The effects of huaier on the gut microbiota structure and intestinal barrier function in MKN45-bearing mice were analyzed by using 16S rRNA sequencing, RT-qPCR, and IHC. UPLC-MS and network pharmacology, as well as in vivo experimental approaches, were employed to investigate the key bioactive constituents of huaier systematically and elucidate the underlying mechanisms by which huaier exerts therapeutic effects against GC. The expression of the PI3K/AKT/SREBP pathway was detected in cancer cells and tissues via Western blot analysis. The safety profile of huaier combined with OXA was verified through serum biochemistry and HE-stained tissue section analyses. Results Huaier inhibited the PI3K/AKT/SREBP pathway by increasing the abundance of Akkermansia muciniphila, reduced lipid droplet deposition, and ultimately enhanced the sensitivity to OXA in the treatment of GC. Conclusion This study demonstrates the value of huaier in gastric cancer treatment by enhancing chemosensitivity and provides novel insights into its systemic therapeutic effects through molecular mechanisms and gut microbiota modulation.

The guideline and item classification approach represents a distinct historical method ology, first introduced by ZHU Xi in his Compendium of Comprehensive Mirror for Aid in Government during the Southern Song Dynasty. LOU Ying later adapted this framework to the field of traditional Chinese medicine, critically analyzing and addressing the limitations of prior academic theories. By drawing upon the rich intellectual traditions of classical texts and historical works, LOU Ying restructured and refined his ideas, ultimately establishing the "guideline and item" medical theory. This innovative framework profoundly influenced LOU Ying′s work, shaping both the compilation of medical texts and the development of novel theoretical approaches in traditional Chinese medicine. In disease differentiation and treatment, LOU Ying proposed the theory of guideline and item classification, that is, taking yin and yang as two guidelines, taking qi and blood, exterior and interior, upper and lower parts, deficiency and excess, cold and heat as ten items, and constructing a syndrome differentiation system focusing on qi and blood, focusing solely on upper and lower parts, distinguishing exterior and interior, carefully examining deficiency and excess, and distinguishing cold and heat. The guideline and item classification system integrates and harmonizes multiple syndrome differentiation method ologies, including the eight-principle pattern identification, viscera syndrome differentiation, differentiation of syndromes according to the pathogenesis of Sanjiao, and qi-blood-fluid pattern identification. As a precursor to modern method of syndrome differentiation and treatment, it possesses unique theoretical significance and considerable clinical relevance. Its applicability to diagnosing and treating various diseases, coupled with its greater operational practicality compared to other methods, highlights its value in contemporary clinical practice. This system offers a complementary and enhanced framework for syndrome differentiation and treatment, warranting further adoption and promotion in the clinical setting.

BACKGROUND: The available evidence regarding the benefits of percutaneous coronary intervention (PCI) on patients receiving dialysis with coronary artery disease (CAD) is limited and inconsistent. This study aimed to evaluate the association between PCI and clinical outcomes as compared with medical therapy alone in patients undergoing dialysis with CAD in China. METHODS: This multicenter, retrospective study was conducted in 30 tertiary medical centers across 12 provinces in China from January 2015 to June 2021 to include patients on dialysis with CAD. The primary outcome was major adverse cardiovascular events (MACE), defined as a composite of cardiovascular death, non-fatal myocardial infarction, and non-fatal stroke. Secondary outcomes included all-cause death, the individual components of MACE, and Bleeding Academic Research Consortium criteria types 2, 3, or 5 bleeding. Multivariable Cox proportional hazard models were used to assess the association between PCI and outcomes. Inverse probability of treatment weighting (IPTW) and propensity score matching (PSM) were performed to account for potential between-group differences. RESULTS: Of the 1146 patients on dialysis with significant CAD, 821 (71.6%) underwent PCI. After a median follow-up of 23.0 months, PCI was associated with a 43.0% significantly lower risk for MACE (33.9% [ n  = 278] vs . 43.7% [ n  = 142]; adjusted hazards ratio 0.57, 95% confidence interval 0.45-0.71), along with a slightly increased risk for bleeding outcomes that did not reach statistical significance (11.1% vs . 8.3%; adjusted hazards ratio 1.31, 95% confidence interval, 0.82-2.11). Furthermore, PCI was associated with a significant reduction in all-cause and cardiovascular mortalities. Subgroup analysis did not modify the association of PCI with patient outcomes. These primary findings were consistent across IPTW, PSM, and competing risk analyses. CONCLUSION This study indicated that PCI in patients on dialysis with CAD was significantly associated with lower MACE and mortality when comparing with those with medical therapy alone, albeit with a slightly increased risk for bleeding events that did not reach statistical significance.

Objective:To analyze the current preparation and usage situation of first-aid drugs in the rescue vehicles in children's medical institutions, and provide references for optimizing the list of emergency drugs.Methods:First-aid drug lists in the rescue vehicles of 12 children's medical institutions from 11 provinces and municipalities in China were collected through questionnaire surveys, and the drugs as well as their quantities were compared. The existing problems in the use of first-aid drugs in the 12 medical institutions were investigated by on-site interviews. The usage information of first-aid drugs in the rescue vehicles of the General Surgery and Cardiology Department of Shanxi Children's Hospital from May 2022 to April 2023 was collected through the hospital information center, and usage frequency and dosage per patient of the drugs were calculated. Descriptive statistical analysis was conducted on the collected data.Results:The first-aid drug lists in 12 hospitals were various, including 7 to 22 kinds of drugs and involving a total of 23 drugs. These mainly included vasoactive drugs, cardiotonic drugs, antiarrhythmic drugs, antiangina and anti-ischemic drugs for the heart, antispasmodic drugs, diuretics, dehydrating drugs, sedative-hypnotic drugs, and glucocorticoids, all of which were injections. The drugs that were included in all the lists of 12 hospitals were epinephrine, dopamine, dexamethasone, furosemide, and atropine. The drug lists of different rescue vehicles throughout the hospital were the same in 4 hospitals, while the lists varied among departments based on their specific clinical needs in the other 8 hospitals. None of the 12 hospitals had a first-aid drug usage manual. The on-site interview results showed that, the existing problems about drug preparation and use in rescue vehicles mainly involved the following 6 aspects: drug types, quantities, labels, storage, procurement, and usage. In Shanxi Children's Hospital, the types and quantities of first-aid drugs in rescue vehicles of General Surgery Department and Cardiology Department were the same. There were 6 and 9 kinds of drugs were used in the 2 departments during rescue operations, respectively. The drugs that were never used in either department included promethazine, lidocaine, diazepam, phenobarbital, raceanisodamine, sodium bicarbonate, atropine, glucose, and calcium gluconate.Conclusions:The phenomenon of unreasonable kinds and quantities of first-aid drugs in the rescue vehicles existed in the children's medical institutions, and the drugs provided did not fully match the actual clinical needs. There was an urgent need for preparation guidelines and usage manuals of first-aid drugs that were suitable for children's medical institutions to enhance the scientificity of drug supply and the correctness of usage.

Objective: Imaging parameters of Chiari malformation type I (CMI) development are not well established. This study aimed to collect evidence of general or specific imaging measurements in patients with CMI, analyze indicators that may assist in determining the severity of CMI, and guide its diagnosis and treatment. Methods: A comprehensive search was conducted across various databases including the Cochrane Library, PubMed, MEDLINE, Scopus, and Embase, covering the period from January 2002 to October 2023, following predefined inclusion criteria. Meta-analyses were performed using RevMan (ver. 5.4). We performed a quantitative summary and systematic analysis of the included studies. This study was registered in the PROSPERO (International Prospective Register of Systematic Reviews) prior to initiation (CRD42023415454). Results: Thirty-three studies met our inclusion criteria. The findings indicated that out of the 14 parameters examined, 6 (clivus length, basal angle, Boogard’s angle, supraocciput lengths, posterior cranial fossa [PCF] height, and volume) exhibited significant differences between the CMI group and the control group. Furthermore, apart from certain anatomical parameters that hold prognostic value for CMI, functional parameters like tonsillar movement, obex displacement, and cerebrospinal fluid dynamics serve as valuable indicators for guiding the clinical management of the disease. Conclusion We collated and established a set of linear, angular, and area measurements deemed essential for diagnosing CMI. However, more indicators can only be analyzed descriptively for various reasons, particularly in prognostic prediction. We posit that the systematic assessment of patients’ PCF morphology, volume, and other parameters at a 3-dimensional level holds promising clinical application prospects.
