To investigate the collective influence of sarcopenia on the extended prognosis of hospitalized elderly individuals with type 2 diabetes mellitus(T2DM). Patients with T2DM aged 65 years and older, who were admitted to the Geriatrics Department of Peking Union Medical College Hospital between January 2017 and January 2021, were consecutively enrolled in the study. The presence of sarcopenia was evaluated based on the diagnostic criteria established by the Asian Working Group for Sarcopenia(AWGS) in 2014. Additionally, assessments were made on the patients' comorbidities, functional status, nutritional status, and geriatric syndromes. Follow-up was conducted through outpatient visits and telephone calls to monitor outcomes such as severe disability, rehospitalization, and all-cause mortality. Cox regression analysis was performed to investigate the impact of concurrent sarcopenia on the long-term prognosis of hospitalized elderly individuals with T2DM. A total of 244 elderly inpatients with T2DM who met specific criteria were included in the study, comprising 110 males(45.1%) and 134 females(54.9%), with ages ranging from 65 to 93 years and a median age of 74 years. Sarcopenia was observed in 25.4%(62/244) of patients. Over a follow-up period of three to seven years(median 5.6 years), elderly T2DM patients with sarcopenia exhibited significantly higher rates of severe disability, rehospitalization, and all-cause death compared to those without sarcopenia(all The prevalence of sarcopenia is notably high among hospitalized elderly patients with T2DM, greatly affecting their long-term prognosis. It is imperative for clinicians to prioritize screening and implement interventions for sarcopenia in elderly T2DM patients to improve their quality of life and overall prognosis.

Objective: This study aims to investigate the associations between genetic variations of pyroptosis pathway related key genes and adverse events (AEs) of postoperative chemoradiotherapy (CRT) in patients with rectal cancer. Methods: DNA was extracted from the peripheral blood which was collected from 347 patients before CRT. Sequenom MassARRAY was used to detect the genotypes of 43 haplotype-tagging single nucleotide polymorphisms (htSNPs) in eight pyroptosis genes, including absent in melanoma 2 (AIM2), caspase-1 (CASP1), caspase-4(CASP4), caspase-5 (CASP5), caspase-11 (CASP11), gasdermin D (GSDMD), gasdermin E (GSDME) and NLR family pyrin domain containing 3 (NLRP3). The associations between 43 htSNPs and AEs were evaluated by the odd ratios (ORs) and 95% confidence intervals (CIs) by unconditional logistic regression models, adjusted for sex, age, clinical stage, tumor grade, Karnofsky performance status (KPS), surgical procedure, and tumor location. Results: Among the 347 patients with rectal cancer underwent concurrent CRT with capecitabine after surgery, a total of 101(29.1%) occurred grade ≥ 2 leukopenia. rs11226565 (OR=0.41, 95% CI: 0.21-0.79, P=0.008), rs579408(OR=1.54, 95% CI: 1.03-2.29, P=0.034) and rs543923 (OR=0.63, 95% CI: 0.41-0.98, P=0.040) were significantly associated with the occurrence of grade ≥ 2 leukopenia. One hundred and fifty-six (45.0%) had grade ≥ 2 diarrhea, two SNPs were significantly associated with the occurrence of grade ≥ diarrhea, including CASP11 rs10880868 (OR=0.55, 95% CI: 0.33-0.91, P=0.020) and GSDME rs2954558 (OR=1.52, 95% CI: 1.01-2.31, P=0.050). In addition, sixty-six cases (19.0%) developed grade ≥2 dermatitis, three SNPs that significantly associated with the risk of grade ≥2 dermatitis included GSDME rs2237314 (OR=0.36, 95% CI: 0.16-0.83, P=0.017), GSDME rs12540919 (OR=0.52, 95% CI: 0.27-0.99, P=0.045) and NLRP3 rs3806268 (OR=1.51, 95% CI: 1.03-2.22, P=0.037). There was no significant difference in the association between other genetic variations and AEs of rectal cancer patients (all P>0.05). Surgical procedure and tumor location had great impacts on the occurrence of grade ≥2 diarrhea and dermatitis (all P<0.01). Conclusion: The genetic variants of CASP4, CASP11, GSDME and NLRP3 are associated with the occurrence of AEs in patients with rectal cancer who received postoperative CRT, suggesting they may be potential genetic markers in predicting the grade of AEs to achieve individualized treatment of rectal cancer.

The discovery of drug targets plays a crucial role in drug research. Accurate information of small molecule drug-protein interaction can be provided by label-free target discovery technology without any structural modification at the small molecule. So, the label-free drug target discovery technology had become the powerful tool to discover the targets of drugs. Due to the “multi-component and multi-target” characteristics of traditional Chinese medicines (TCMs), the research on its targets and mechanism had been restricted. Based on potential of the label-free target discovery technology in the research of TCMs, this paper summarized the label-free target discovery technology and its application in TCMs research. It will provide a reference for the discovery of targets of TCMs and a new view for promoting the modernization of TCMs.

Glucagon-like peptide-1 (GLP-1) is a major hormone of incretin hormone and gut-brain axis, which is related to the control of energy homeostasis and the occurrence of obesity. In addition to suppressing appetite, GLP-1 has neuroprotective effects by acting on areas of the brain involved in stress response and mood regulation. Depression is a common mental disease, and GLP-1 is closely related to depression. This article reviews the role and mechanism of GLP-1 in depression.

HSP90 is a widely distributed molecular chaperone that participates in a variety of cellular processes and plays an important role in the meiosis of germ cells. However, its role in the gonadal development of hermaphroditic Whitmania pigra is not yet clear. To explore the effect of HSP90 on the germ cell development of Wh. Pigra, this study cloned the wpHSP90 gene, performed bioinformatics analysis, and measured its expression levels. The results showed that the cloned wpHSP90 was 2 592 bp in length, with an open reading frame(ORF) of 2 373 bp, encoding 790 amino acids. Prediction analysis revealed 85 phosphorylation modification sites on serine, threonine, and tyrosine residues of the wpHSP90 protein. Structural domain prediction and multiple sequence alignment results showed that wpHSP90 contained two conserved domains of HSP90 and exhibited the highest homology with Helobdella robusta, with a sequence similarity of 80.72%. RT-qPCR results showed that the relative expression level of wpHSP90 in the gonads of 5-month-old Wh. pigra was positively correlated with temperature within the range of 12 ℃ to 28 ℃. The expression level in the female gonads was significantly higher than in the male gonads and correlated with the trend of germ cell development in the ovaries and testes. In conclusion, wpHSP90 may be involved in regulating the development of germ cells, particularly oocytes, in Wh. pigra. This study provides a reference for further research on the gonadal development mechanism in Wh. pigra.

Objective:To systematically evaluate the efficacy and safety of general anesthesia versus conscious sedation in patients with endovascular therapy for acute ischemic stroke.Methods:Databases, including English databases PubMed, Embase and Cochrane, as well as Chinese databases Wan Fang Data and CNKI, were screened for randomized controlled trials (RCT) of general anesthesia versus conscious sedation on the effect of endovascular treatment for acute anterior circulation ischemic stroke. The searching period was from the establishment of databases to July 14, 2022. Two researchers independently screened literatures, extracted data and evaluated the risk of bias. And meta-analysis was performed using RevMan5.3 software.Results:A total of 7 RCTs involving 923 patients were included, with 461 in the general anesthesia group and 462 in the other. As the meta-analysis showing, general anesthesia could significantly improve the good outcomes (modified Rankin Scale score≤2) at 3 months after endovascular treatment in comparison with conscious sedation ( OR=1.34, 95% CI 1.01-1.78, P=0.04), and significantly increased the rate of successful revascularization ( OR=1.87, 95% CI 1.32-2.65, P<0.001). In addition, there were no statistically significant differences between the two groups in mortality ( OR=0.93, 95% CI 0.66-1.29, P=0.65), symptomatic intracranial hemorrhage ( OR=0.88, 95% CI 0.57-1.35, P=0.55) and intervention-related complications ( OR=0.83, 95% CI 0.50-1.36, P=0.46). However, general anesthesia was associated with higher risk for both 20% reduction in mean arterial pressure ( OR=4.76, 95% CI 1.49-15.19, P=0.008) and pneumonia ( OR=2.58, 95% CI 1.51-4.39, P<0.001). Conclusions:Compared with conscious sedation, endovascular treatment under general anesthesia in patients with acute anterior circulation ischemic stroke may contribute to better outcomes and higher successful revascularization. However, this method will lead to the risk of blood pressure variability and the incidence of pneumonia.
