Objective To analyze the prevalence status of cardiometabolic risk factor (CMRF) and its aggregation among workers engaged in new forms of employment. Methods A total of 5 429 new employment workers (including couriers, online food delivery workers, and ride hailing drivers) who underwent health medical examinations at a tertiary hospital in Beijing City were selected as the research subjects using the judgment sampling method. Data on waist circumference, blood pressure, blood glucose, and blood lipid levels were collected to analyze their CMRF [central obesity, elevated blood pressure, elevated blood glucose, elevated triglycerides, and reduced high-density lipoprotein cholesterol (HDL-C)] and their aggregation (with ≥ 2 of the above 5 risk factors) status. Results The detection rates of central obesity, elevated blood pressure, elevated blood glucose, elevated triglycerides, and reduced HDL-C were 61.2%, 38.2%, 29.5%, 40.9% and 22.6%, respectively. The detection rates of CMRF aggregation was 57.8%. The result of multivariable logistic regression analysis showed that male, age ≥45 years, smoking, overweight, and obesity were risk factors for CMRF aggregation (all P<0.05). Conclusion The detection rate of CMRF and its aggregation among workers with new forms of employment in Beijing City is relatively high. Targeted prevention and control efforts should be strengthened for high-risk populations, especially males, workers aged ≥45 years, smokers, and those who are overweight or obese.

Macroautophagy (referred to as autophagy hereafter) is a major intracellular lysosomal degradation pathway that is responsible for the degradation of misfolded/damaged proteins and organelles. Previous studies showed that autophagy protects against acetaminophen (APAP)-induced injury (AILI) via selective removal of damaged mitochondria and APAP protein adducts. The lysosome is a critical organelle sitting at the end stage of autophagy for autophagic degradation via fusion with autophagosomes. In the present study, we showed that transcription factor EB (TFEB), a master transcription factor for lysosomal biogenesis, was impaired by APAP resulting in decreased lysosomal biogenesis in mouse livers. Genetic loss-of and gain-of function of hepatic TFEB exacerbated or protected against AILI, respectively. Mechanistically, overexpression of TFEB increased clearance of APAP protein adducts and mitochondria biogenesis as well as SQSTM1/p62-dependent non-canonical nuclear factor erythroid 2-related factor 2 (NRF2) activation to protect against AILI. We also performed an unbiased cell-based imaging high-throughput chemical screening on TFEB and identified a group of TFEB agonists. Among these agonists, salinomycin, an anticoccidial and antibacterial agent, activated TFEB and protected against AILI in mice. In conclusion, genetic and pharmacological activating TFEB may be a promising approach for protecting against AILI.

Congenital anomalies of the kidneys and urinary tracts（CAKUT）include a wide range of structural malformations resulting from defects in the morphogenesis of the kidney and the urinary tract. Congenital renal anomaly is common in CAKUT. The pathogenesis of congenital renal anomaly is considered to be multi-factor，involving maternal or external environment，and heredity. With the continuous progress of molecular diagnosis technology，genetic factors have attracted more and more attention. The PBX1 gene was initially discovered by the formation of an E2A-PBX1 fusion gene from a t（1；19）（q23；p13.3）chromosome translocation，which results in pre-B-cell lymphoblastic leukemia.PBX1 gene mutation can cause congenital renal and urogenital malformation syndromes with or without hearing loss，ear abnormalities，and developmental delay. This review deepens the understanding of the role of genes in regulating kidney development by describing the embryonic basis of kidney development，the structure and function of the PBX1 gene，and the pathogenesis of renal anomalies caused by mutations. Further，it summarizes the phenotype and genotype of the PBX1 gene，in order to promote the diagnosis，treatment，and determination progression of congenital renal anomaly.

Objective To investigate the effect of anti-angiogenic drug Sitravatinib combined with poly(adenosine diphosphate[ADP]-ribose)polymerase inhibitor(PARPi)Niraparib on mucosal melanoma cell lines and its possible mechanism.Methods The CCK8 assay was used to detect the maximal half inhibitory concentration(IC50)of Sitravatinib and Niraparib targeting at mucosal melanoma(MM)cell lines.CompuSyn was used to detect the Combination Index(CI)in different concentrations of the two drugs.Flow cytometry was used to detect the effect of drugs on cell apoptosis.Colony formation assay was used to detect the effect of drugs on cell proliferation.Western blot was used to detect the protein expressions and RT-qPCR was used to detect mRNA expression.Results CI values was respectively 0.19 and 0.15 for Sitravatinib(2 μmol/L)in combination with Niraparib(20 μmol/L)in a human vaginal maligant melanoma cell line(HMVII)and a metastasis inguinal lymph node of vulvar malignant melanoma cell line(GAK).Compared with the control group and single-drug groups,the cell proliferation of the combination group was significantly reduced(P＜0.05 or P＜0.01 or P＜0.001).The cell apoptosis rate was signifi-cantly increased(P＜0.01 or P＜0.001).The protein and mRNA expression of apoptosis-related biomarkers signifi-cantly increased(P＜0.001);In addition,the protein and mRNA expression of cell autophagy biomarkers signifi-cantly increased(P＜0.01 or P＜0.001).The protein expression of DNA damage marker significantly increased.Moreover,compared with the control group,The expression of radiation sensitive protein 51(RAD51)recombinase in the Sitravatinib single-drug group and combination group significantly reduced.As the dose of Sitravatinib gradu-ally increased up to 2 μmol/L,the protein and mRNA expression of RAD51 both significantly reduced(P＜0.05 or P＜0.01),the mRNA expression of BRCA1 and BRCA2 also significantly reduced(P＜0.05 or P＜0.01 or P＜0.001).Conclusions Sitravatinib combined with Niraparib inhibits the proliferation of mucosal melanoma cells,induces cell apoptosis and promotes autophagy.The mechanism is potentially related to the inhibition of ho-mology-dependent recombination repairs(HRR).

Objective To analyze the evaluation results of health enterprises in Beijing City and their influencing factors. Methods A total of 40 enterprises that passed the health enterprise evaluation in Beijing from 2021 to 2022 were selected as the study subjects using the judgment sampling method. The total evaluation scores and influencing factors were analyzed based on the size, nature, industry classification, and establishment time of the enterprises. Results The total evaluation score of the 40 health enterprises was (553.1±18.4) points. Scores for the primary evaluation indicators, including management organization and system, occupational disease prevention measures, health environment, health promotion measures, prevention measures for occupational stress caused damage, and musculoskeletal injury prevention measures, were (94.0±4.8), (94.0±4.3), (94.5±3.8), (89.7±4.8), (89.6±4.6), and (91.4±5.9) points, respectively. The result of multiple linear regression analysis showed that, large enterprises had higher total evaluation scores than medium enterprises and micro and small enterprises after controlling for confounding factors such as industry classification and establishment time (all P<0.10). The total evaluation scores of private enterprises and foreign-funded enterprises were lower than that of state-owned or state-participated enterprises (all P<0.10). Conclusion Enterprise size and nature are influencing factors for the total evaluation score of health enterprises. It is necessary to enhance resource and policy support for medium-sized, micro and small enterprises and private enterprises to improve the development of the health enterprises.

Objective:To investigate the efficacy and safety of protein A immunoadsorption (PAIA) combined with rituximab (RTX) in highly sensitized patients who underwent haplo-hematopoietic stem cell transplantation (haplo-HSCT) .Methods:The clinical data of 56 highly sensitized patients treated with PAIA and RTX before haplo-HSCT at the First Affiliated Hospital of Soochow University and Soochow Hopes Hematonosis Hospital between March 2021 and June 2023 were retrospectively analyzed. The number of human leukocyte antigen (HLA) antibody types and the mean fluorescence intensity (MFI), humoral immunity, adverse reactions during adsorption, and survival within 100 days before and after adsorption were measured.Results:After receiving the PAIA treatment, the median MFI of patients containing only HLA Ⅰ antibodies decreased from 7 859 (3 209-12 444) to 3 719 (0-8 275) ( P<0.001), and the median MFI of HLA Ⅰ+Ⅱ antibodies decreased from 5 476 (1 977-12 382) to 3 714 (0-11 074) ( P=0.035). The median MFI of patients with positive anti-donor-specific antibodies decreased from 8 779 (2 697-18 659) to 4 524 (0–15 989) ( P<0.001). The number of HLA-A, B, C, DR, and DQ antibodies in all patients decreased after the PAIA treatment, and the differences were statistically significant (A, B, C, DR: P<0.001, DQ: P<0.01). The humoral immune monitoring before and after the PAIA treatment showed a significant decrease in the number of IgG and complement C3 ( P<0.001 and P=0.002, respectively). Forty-four patients underwent HLA antibody monitoring after transplantation, and the overall MFI and number of antibody types decreased. However, five patients developed new antibodies with low MFI, and nine patients continued to have high MFI. The overall survival, disease-free survival, non-recurrent mortality, and cumulative recurrence rates at 100 days post-transplantation were 83.8%, 80.2%, 16.1%, and 4.5%, respectively. Conclusions:The combination of PAIA and RTX has a certain therapeutic effect and good safety in the desensitization treatment of highly sensitive patients before haplo-HSCT.

Objective: To evaluate the effectiveness and safety of modified Xiaoyao powder for postpartum depression (PPD) by conducting a systematic review of randomized controlled trials (RCTs). Methods: The Chinese National Knowledge Infrastructure Databases (CNKI), the Chinese Scientific Journals Database (VIP), Wanfang, Google Scholar, the SinoMed, Embase, Cochrane Library, and PubMed databases were searched from their inception to April 25, 2023. The Cochrane Risk of Bias tool was used to assess the quality of the trials. We applied the risk ratio to present dichotomous data and the mean difference to present continuous data. Data with similar characteristics were pooled for meta-analysis and heterogeneity was assessed using I2. Results: This review included 35 trials involving 2848 participants. The quality of the included studies was low (unclear randomization processes and insufficient reporting of blinding). Participants treated with modified Xiaoyao powder plus Western medicine showed lower Hamilton Depression Scale (HAMD) depression score than those who used Western medicine alone (mean difference = −2.15; 95% confidence interval:−2.52 to 1.78; P < .00001), and higher effective rate (relative risk = 1.19; 95% confidence interval: 1.15 to 1.24; P < .00001), When comparing modified Xiaoyao alone with Western medicine, the HAMD depression score remained low, however, the efficacy rate was higher in the modified Xiaoyao group. Regarding adverse events, the modified Xiaoyao group reported weight gain, nausea, and diarrhea, but no severe adverse events were reported. Conclusion Modified Xiaoyao may help relieve depression in PPD when used alone or in combination with Western medicine, with minor side effects. Therefore, future high-quality, large-sample size RCTs are warranted.
