Cells undergo glucose metabolism reprogramming under the influence of the inflammatory microenvironment, changing their primary mode of energy supply from oxidative phosphorylation to aerobic glycolysis. This process is involved in all stages of inflammation-related diseases development. Glucose metabolism reprogramming not only changes the metabolic pattern of individual cells, but also disrupts the metabolic homeostasis of the body microenvironment, which further promotes aerobic glycolysis and provides favourable conditions for the malignant progression of inflammation-related diseases. The metabolic enzymes, transporter proteins, and metabolites of aerobic glycolysis are all key signalling molecules, and drugs can inhibit aerobic glycolysis by targeting these specific key molecules to exert therapeutic effects. This paper reviews the impact of glucose metabolism reprogramming on the development of inflammation-related diseases such as inflammation-related tumours, rheumatoid arthritis and Alzheimer's disease, and the therapeutic effects of drugs targeting glucose metabolism reprogramming on these diseases.

In metabolic diseases, the accumulation of reactive oxygen species and oxidative stress are closely associated with ferroptosis. As a key regulatory factor, the imbalance between glycolysis and fatty acid metabolism can participate in ferroptosis directly or indirectly, thereby regulating the occurrence and development of various metabolic diseases. The essence of ferroptosis is a new regulatory cell death mode, which is caused by the excessive accumulation of iron-dependent lipid peroxide. It is closely related to glycolysis and fatty acid metabolism, which plays an important role in metabolic diseases. This regulatory cell death mode is significantly distinguished from other programmed cell death modes and has unique changes in cell morphology, symbolic characteristics and mechanisms. This paper first illustrates the main mechanism of glycolysis and fatty acid metabolism imbalance in the occurrence of ferroptosis, then reviews the research progress of ferroptosis in tumor, diabetes, rheumatoid arthritis and other metabolic diseases, and finally reveals the internal connection between glycolysis-fatty acid metabolism imbalance and ferroptosis, as well as its impacts on metabolic diseases, which provide new strategies for the prevention and treatment of metabolic diseases.

The chemical constituents from the stems and leaves of Cratoxylum cochinchinense were isolated and purified using silica gel, ODS gel, and Sephadex LH-20 gel column chromatography, as well as preparative HPLC. The chemical structures of all isolated compounds were identified on the basis of their physicochemical properties, spectroscopic analyses, and the comparison of their physicochemical and spectroscopic data with the reported data in literature. As a result, 21 compounds were isolated from the 90% ethanol extract of the stems and leaves of C. cochinchinense, which were identified as cratocochine(1), 1-hydroxy-3,7-dimethoxyxanthone(2), 1-hydroxy-5,6,7-trimethoxyxanthone(3), ferrxanthone(4), 3,6-dihydroxy-1,5-dimethoxyxanthone(5), 3,6-dihydroxy-1,7-dimethoxyxanthone(6), 1,2,5-trihydroxy-6,8-dimethoxyxanthone(7), securixanthone G(8), gentisein(9), 3,7-dihydroxy-1-methoxyxanthone(10), pancixanthone B(11), garcimangosxanthone A(12), pruniflorone L(13), 9-hydroxy alabaxanthone(14), cochinchinone A(15), luteolin(16), 3,5'-dimethoxy-4',7-epoxy-8,3'-neolignane-5,9,9'-triol(17), N-benzyl-9-oxo-10E,12E-octadecadienamide(18), 15-hydroxy-7,13E-labdadiene(19), stigmasta-4,22-dien-3-one(20), and stigmast-5-en-3β-ol(21). Among these isolates, compound 1 was a new xanthone, compounds 2-5, 7, 8, 12, and 16-21 were isolated from the Cratoxylum plant for the first time, and compounds 11 and 13 were obtained from C. cochinchinense for the first time. Furthermore, all isolated compounds 1-21 were appraised for their anti-rheumatoid arthritis activities by MTS method through measuring their anti-proliferative effect on synoviocytes in vitro. As a result, xanthones 1-15 displayed notable anti-rheumatoid arthritis activities, which showed inhibitory effects on the proliferation of MH7A synoviocytes with the IC_(50) values ranging from(8.98±0.12) to(228.68±0.32) μmol·L~(-1).

Objective: To understand the incidence of chronic obstructive pulmonary disease (COPD) in the Suzhou cohort, and explore the risk factors for the development of COPD in Suzhou, and provide a scientific basis for COPD prevention. Methods: This study was based on the China Kadoorie Biobank project in Wuzhong District, Suzhou. After excluding individuals with airflow obstruction and self-reported chronic bronchitis, emphysema, or pulmonary heart disease at baseline, 45 484 individuals were finally included in the analysis. Cox proportional risk models were used to analyze risk factors of COPD and calculate hazard ratios and 95% confidence interval (CI) in the Suzhou cohort. The effect modifications of smoking on the association between other risk factors and COPD were evaluated. Results: Complete follow-up was available through December 31, 2017. Participants were followed up for a median of 11.12 years, and 524 individuals were diagnosed with COPD during the follow-up period; the incidence was 105.54 per 100 000 person-years. Multivariate Cox proportional risk regression models showed that age (HR=3.78, 95%CI:3.32-4.30), former smoking (HR=2.00, 95%CI:1.24-3.22), current smoking (<10 cigarettes/day, HR=2.14, 95%CI:1.36-3.35;≥10 cigarettes/day, HR=2.69, 95%CI:1.60-4.54), history of respiratory disease (HR=2.08, 95%CI:1.33-3.26), daily sleep duration ≥10 hours (HR=1.41, 95%CI:1.02-1.95) were associated with increased risk of COPD. However, education level of primary school and above (primary or junior high school, HR=0.65, 95%CI:0.52-0.81; high school and above, HR=0.54, 95%CI:0.33-0.87), consuming fresh fruit daily (HR=0.59, 95%CI:0.42-0.83) and consuming spicy food weekly (HR=0.71, 95%CI:0.53-0.94) were associated with reduced risk of COPD. Conclusions: The incidence of COPD is low in Suzhou. Older age, smoking, history of respiratory disease, and long sleep duration were risk factors for the development of COPD in the Suzhou cohort.

Medicinal plants or Chinese materia medica (CMM) are now attracting worldwide attention as they have increasingly prominent advantages over chemical drugs in disease treatment and healthcare. Since the 1990s, World Health Organization (WHO) and International Organization for Standardization established the Technical Committee of Traditional Chinese Medicine (ISO/TC 249) have carried out the development of quality standards on medicinal plants or CMMs respectively, and a considerable number of monographs and international standards have been published. Since the two international organizations adhere to different principles, the standards they develop naturally have different emphasis. Driven by market demand and international trade, ISO mainly takes quality, efficacy and safety into consideration when developing standards, while WHO pays more attention to clinical practice, quality control and medication guidance. Up to now, there is a lack of comparative analysis on the records, background, principles, basic content, and main requirements of quality standards on medicinal plants or CMMs respectively published by WHO and ISO. Therefore, based on international standards of CMM developed by ISO/TC 249 platform and WHO Monographs on Selected Medicinal Plants, this paper systematically compares the purposes, selected principles, standard-developing process, basic content, and main quality requirements to summarize their similarities and differences, and find their merits, aiming to serve as a reference to the development of international standards for CMMs that helps them go global.

BACKGROUND:
Currently, more and more infertility couples are opting for combined acupuncture to improve success rate of in vitro fertilization (IVF). However, evidence from acupuncture for improving IVF pregnancy outcomes remains a matter of debate.
OBJECTIVE:
To quantitatively summarized the evidence of the efficacy of acupuncture among women undergoing IVF by means of systematic review and meta-analysis.
METHODS:
Four English (PubMed, Web of Science, EMBASE, and Cochrane Register of Controlled Clinical Trials) and Four Chinese databases (Wanfang Databases, Chinese National Knowledge Infrastructure, Chinese Science and Technology Periodical Database, and SinoMed) were searched from database inception until July 2, 2023. Randomized controlled trials (RCTs) that evaluated the acupuncture's effects for women undergoing IVF were included. The subgroup analysis was conducted with respect to the age of participants, different acupuncture types, type of control, acupuncture timing, geographical origin of the study, whether or not repeated IVF failure, and acupuncture sessions. Sensitivity analyses were predefifined to explore the robustness of results. The primary outcomes were clinical pregnancy rate (CPR) and live birth rate (LBR), and the secondary outcomes were ongoing pregnancy rate and miscarriage rate. Random effects model with I2 statistics were used to quantify heterogeneity. Publication bias was estimated by funnel plots and Egger's tests.
RESULTS:
A total of 58 eligible RCTs representing 10,968 women undergoing IVF for pregnant success were identifified. Pooled CPR and LBR showed a signifificant difference between acupuncture and control groups [69 comparisons, relative risk (RR) 1.19, 95% confifidence intervals (CI) 1.12 to 1.25, I2=0], extremely low evidence; 23 comparisons, RR 1.11, 95%CI 1.02 to 1.21, I2=14.6, low evidence, respectively). Only transcutaneous electrical acupoint stimulation showed a positive effect on both CPR (16 comparisons, RR 1.17, 95%CI 1.06 to 1.29; I2=0, moderate evidence) and LBR (9 comparisons, RR 1.20, 95%CI 1.04 to 1.37; I2=8.5, extremely low evidence). Heterogeneity across studies was found and no studies were graded as high-quality evidence.
CONCLUSION
Results showed that the convincing evidence levels on the associations between acupuncture and IVF pregnant outcomes were relatively low, and the varied methodological design and heterogeneity might inflfluence the fifindings. (Registration No. PROSPERO CRD42021232430).

Coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2, is a major public health issue. The epidemic is unlikely to be contained until the global launch of safe and effective vaccines that could prevent serious illnesses and provide herd immunity. Although most patients have mild flu-like symptoms, some develop severe illnesses accompanied by multiple organ dysfunction. The identification of pathophysiology and early warning biomarkers of a severe type of COVID-19 contribute to the treatment and prevention of serious complications. Here, we review the pathophysiology, early warning indicators, and effective treatment of Chinese and Western Medicine for patients with a severe type of COVID-19.

Objective: To explore the heterogeneity and correlation of clinical phenotypes and genotypes in children with disorders of sex development (DSD). Methods: A retrospective study of 1 235 patients with clinically proposed DSD in 36 pediatric medical institutions across the country from January 2017 to May 2021. After capturing 277 DSD-related candidate genes, second-generation sequencing was performed to analyzed the heterogeneity and correlation combined with clinical phenotypes. Results: Among 1 235 children with clinically proposed DSD, 980 were males and 255 were females of social gender at the time of initial diagnosis with the age ranged from 1 day of age to 17.92 years. A total of 443 children with pathogenic variants were detected through molecular genetic studies, with a positive detection rate of 35.9%. The most common clinical phenotypes were micropenis (455 cases), hypospadias (321 cases), and cryptorchidism (172 cases) and common mutations detected were in SRD5A2 gene (80 cases), AR gene (53 cases) and CYP21A2 gene (44 cases). Among them, the SRD5A2 mutation is the most common in children with simple micropenis and simple hypospadias, while the AMH mutation is the most common in children with simple cryptorchidism. Conclusions: The SRD5A2 mutation is the most common genetic variant in Chinese children with DSD, and micropenis, cryptorchidism, and hypospadias are the most common clinical phenotypes. Molecular diagnosis can provide clues about the biological basis of DSD, and can also guide clinicians to perform specific clinical examinations. Target sequence capture probes and next-generation sequencing technology can provide effective and economical genetic diagnosis for children with DSD.

ObjectiveTo explore the effect of Qingfei Jiangmai decoction (QJD) on the content of mercapturic acids in urine in healthy people amid PM2.5 (particles 2.5 microns or less in size) pollution. MethodA total of 84 healthy students of 18-30 years old in Beijing were recruited and they were randomized into the test group (42 in total, with 1 dropout) and control group (42 in total, with 3 dropouts). During the pollution, the test group and the control group respectively took QJD granules and placebo for 7 days (1 bag/time, 2 times/day), and another 7-day intervention with the same drugs was performed at an interval of 4 weeks. The time-activity patterns were recorded during the intervention. On-line solid phase extraction-liquid chromatography/tandem mass spectrometry (SPE-LC-MS/MS) was performed to detect the content of PM2.5-related metabolites S-phenylmercapturic acid (SPMA), 3-hydroxypropylmercapturic acid (3-HPMA), 3-hydroxy-1-methylpropylmercapturic acid (HMPMA), N-acetyl-S-(2-nitrile ethyl)-L-cysteine (CEMA), and N-acetyl-S-(2-hydroxy ethyl)-L-cysteine (HEMA) in urine before and after intervention. Statistical analysis was followed. ResultThe content of CEMA, HEMA, 3-HPMA, and HMPMA in the test group was all higher after the intervention than before the intervention, with the significant difference in HEMA (P<0.05). After intervention, content of HEMA and SPMA was significantly higher in the test group than in the control group (P<0.05), and the difference in HEMA (Z=-3.614, P<0.01) and HMPMA (Z=-1.988, P<0.05) before and after invention in the test group was significantly larger than that in the control group. After the intervention, HEMA in the test group was significantly higher than that in the control group (F=7.597, P<0.01). ConclusionDuring PM2.5 pollution, QJD can increase the excretion of HEMA, a metabolite of ethylene oxide, in the urine of healthy people in Beijing, and enhance the detoxification process of toxic components in PM2.5, which is of great value in preventing and treating haze-related illnesses.
