Objective:To report construction of Evidence-Based Guidelines for the Diagnosis and Treatment of Distal Radius Fractures in Adults (2024) using the Delphi method.Methods:Literature related to the study of adult distal radius fractures was fully searched for and evaluated. An expert group was established from representative experts from all over the nation. The related clinical issues were established by consulting the experts in the form of electronic questionnaires, strictly following the Delphi research method. After the first draft of Evidence-Based Guidelines for the Diagnosis and Treatment of Distal Radius Fractures in Adults (2024) was written, an expert consultation questionnaire was designed for the recommendation opinions to determine the recommendation strength.Results:The clinical issues were determined by 2 rounds of correspondence based on the Delphi method. For the both rounds of correspondence, the questionnaire recovery rates were respectively 88.68% (47/53) and 98.11% (52/53), and the expert authority coefficients >0.7. According to the screening criteria based on the importance of clinical issues (mean importance score <3.5 points or a coefficient of variation ≥0.25 points and a full score ratio <30%) and expert opinions, a total of 40 clinical issues were deleted in the first round of determination of clinical issues, and a total of 5 clinical issues deleted in the second round of determination of clinical issues. The reliability analysis of the results of the 2 rounds of questionnaires showed that the Cronbach α coefficient was >0.9. In the questionnaire to determine the recommendation strength, according to the screening criteria for the consistency of recommendation strength (consistency ≥ 70%) and expert opinions, a total of 26 recommendations were screened in the first round. In the second round when the remaining 4 recommendations were investigated, one recommendation reached the consistency of recommendation strength ≥ 70%. Eventually, 27 recommendations were formed.Conclusion:The Evidence-Based Guidelines for the Diagnosis and Treatment of Distal Radius Fractures in Adults (2024) constructed using the Delphi method shows good scientific validity, authority, and reliability, providing methodological references for guideline development and research.

Using chemoproteomic techniques, we first identified EIF2AK2, eEF1A1, PRDX3 and VPS4B as direct targets of berberine (BBR) for its synergistically anti-inflammatory effects. Of them, BBR has the strongest affinity with EIF2AK2 via two ionic bonds, and regulates several key inflammatory pathways through EIF2AK2, indicating the dominant role of EIF2AK2. Also, BBR could subtly inhibit the dimerization of EIF2AK2, rather than its enzyme activity, to selectively modulate its downstream pathways including JNK, NF-κB, AKT and NLRP3, with an advantage of good safety profile. In EIF2AK2 gene knockdown mice, the inhibitory IL-1β, IL-6, IL-18 and TNF-α secretion of BBR was obviously attenuated, confirming an EIF2AK2-dependent anti-inflammatory efficacy. The results highlight the BBR's network mechanism on anti-inflammatory effects in which EIF2AK2 is a key target, and inhibition of EIF2AK2 dimerization has a potential to be a therapeutic strategy against inflammation-related disorders.

A series of new monobactam sulfonates is continuously synthesized and evaluated for their antimicrobial efficacies against Gram-negative bacteria. Compound 33a (IMBZ18G) is highly effective in vitro and in vivo against clinically intractable multi-drug-resistant (MDR) Gram-negative strains, with a highly druglike nature. The checkerboard assay reveals its significant synergistic effect with β-lactamase inhibitor avibactam, and the MIC values against MDR enterobacteria were reduced up to 4-512 folds. X-ray co-crystal and chemoproteomic assays indicate that the anti-MDR bacteria effect of 33a results from the dual inhibition of the common PBP3 and some class A and C β-lactamases. Accordingly, preclinical studies of 33a alone and 33a‒avibactam combination as potential innovative candidates are actively going on, in the treatment of β-lactamase-producing MDR Gram-negative bacterial infections.

Objective: To explore the correlation of age at menarche and prehypertension in female college students. Methods: Age at menarche of 558 female college students was collected, while blood pressure, height and weight were measured, and body mass index(BMI) was calculated. Results: Average age at menarche was (12.48±0.95) years, prevalence of prehypertension was 17.56% (98/558). The age of menarche was 8-11, 12, 13, 14, 15-19, and the prevalence of hypertension was 30.95%, 10.00% , 17.31%, 10.81%, 31.58% respectively, U shape association was observed in the association between prehypertension with age at menarche, lowest when age at menarche was <12 years. There was no significant difference in prehypertension between age at menarche was 13, 14 years old with 12-year-old group, those age at menarche 8-11 or 15-19 had a significantly higher risk of developing prehypertension than those 12-year-old( OR =4.03, 4.15, P <0.05). Conclusion Early or late menarche is associated with high blood pressure, appropriate intervention for girls with early menarche and obesity may be beneficial in reducing their future hypertension.

Gadoxetate magnetic resonance imaging (MRI) is widely used in clinical practice for liver imaging. For optimal use, we must understand both its advantages and limitations. This article is the outcome of an online advisory board meeting and subsequent discussions by a multidisciplinary group of experts on liver diseases across the Asia-Pacific region, first held on September 28, 2020. Here, we review the technical considerations for the use of gadoxetate, its current role in the management of patients with hepatocellular carcinoma (HCC), and its relevance in consensus guidelines for HCC imaging diagnosis. In the latter part of this review, we examine recent evidence evaluating the impact of gadoxetate on clinical outcomes on a continuum from diagnosis to treatment decision-making and follow-up. In conclusion, we outline the potential future roles of gadoxetate MRI based on an evolving understanding of the clinical utility of this contrast agent in the management of patients at risk of, or with, HCC.

Objective:This study uses two markers of resting-state functional MRI (r-fMRI) to investigate changes in spontaneous neural activity and their correlation with postpartum depression (PPD) severity.Methods:A total of 15 individuals with PPD, who met the diagnostic criteria for DSM-5 unipolar depression, 24-Item Hamilton Depression Scale (HAMD 24) scores greater than 20, Edinburgh Postnatal Depression Scale (EPDS) score≥12, and 16 postpartum healthy mothers (control group) matched with age and education were examined using r-fMRI. Two-sample t-test was used to compare the amplitude of low-frequency fluctuation (ALFF) and regional homogeneity (ReHo) values between groups. Pearson correlation analysis was used to determine the correlation between the ALFF and ReHo of the abnormal brain region and the HAMD 24 and EPDS scores. Results:Compared with the healthy control (HC), PPD showed increased ALFF in the right cerebellum anterior lobe culmen and the left dorsolateral prefrontal cortex (DLPFC), and decreased ALFF in the right parietal lobe (individual voxel P<0.005, cluster size >10 voxels, Alphasim correction). PPD had increased ReHo values in the left superior?frontal?gyrus,?orbital?part, inferior?frontal?gyrus,?orbital?part, middle?frontal?gyrus, precuneus, inferior?parietal lobule than HC. Decreased ReHo values were found in the right inferior?occipital?gyrus, inferior?frontal?gyrus, frontal lobule and left cerebellum inferior semi-lunar lobule (individual voxel P<0.005, cluster size>10 voxels, Alphasim correction). The ALFF value of the left DLPFC was positively correlated with the HAMD 24 score in PPD ( r=0.585, P=0.022). Age, body mass index and education years of each subject was included as covariates, partial correlation coefficient was still statistically significant ( r = 0.561, P = 0.046). Conclusion:This r-fMRI study suggested that changes in the spontaneous neural activity of these regions were related to emotional responses. PPD cases with high ALFF values in the left DLPFC had severe depression.
