Methods: From March 2020 to March 2023, 100 inpatients with DS were classified into groups A, B, C, and D based on the CARDS classification system. Preoperative radiological data were analyzed to measure the severity of central canal stenosis, facet joint arthropathy, intervertebral disc herniation, and spinal epidural lipomatosis, osteophyte formation, range of motion (ROM), and computed tomography value of the vertebral bodies. The radiological characteristics and clinical contraindications for OLIF were compared among the groups. Results: Of the 100 patients, 51% had clinical contraindications for OLIF, which included 85%, 25%, 62.5%, and 20% of patients in groups A, B, C, and D, respectively. Compared with group B, group A demonstrated greater severity of central canal stenosis, whereas group C showed a higher degree of facet joint arthropathy. More patients in groups A and C had severe central canal stenosis. Regarding the ROM results, group A had segmental stiffness, whereas group D presented relatively unstable slip segments. Conclusions Patients with different DS subtypes have varied radiological characteristics. Groups B and D are suitable candidates for OLIF. Most patients in group A are unsuitable for OLIF because of bony hyperplasia, severe spinal stenosis, and segmental stiffness.

Purpose: This study aimed to investigate the molecular characteristics associated with better prognosis in breast cancer. Methods: We performed targeted sequencing of 962 genes in 56 samples, categorizing them into long-term and short-term survival groups as well as chemotherapy-sensitive and chemotherapy-resistant groups for further analyses. Results: The results indicated that the tumor mutational burden values were significantly higher in the short-term survival and chemotherapy-resistant groups (p = 0.008 and p = 0.003, respectively). Somatic mutation analysis revealed that the mutation frequencies of BCL9L and WHSC1 were significantly lower in the long-term survival group than those in the short-term survival group (p = 0.029 and p = 0.024, respectively). CREB-regulated transcription coactivator 1 (CRTC1) mutations occurred significantly more frequently in the chemotherapy-resistant group (p = 0.027) and were associated with shorter progression-free survival (p = 0.036).Signature weighting analysis showed a significant increase in Signature.3, which is associated with homologous recombination repair deficiency in the chemotherapy-sensitive group (p = 0.045). Conversely, signatures related to effective DNA repair mechanisms, Signature.1 and Signature.15, were significantly reduced (p = 0.002 and p < 0.001, respectively). Kyoto Encyclopedia of Genes and Genomes pathway analysis indicated that gene mutations were significantly enriched in the JAK-STAT signaling pathway. Conclusion This study, through intergroup comparative analysis, found that immunotherapy (using programmed death 1/programmed death-ligand 1 inhibitors) may improve the prognosis of patients with short survival and chemotherapy resistance. Additionally, the study revealed that mutations in BCL9L and WHSC1 could serve as biomarkers for breast cancer prognosis, while CRTC1 mutations and Signature.3 could predict chemotherapy response. The study also found that the JAK-STAT pathway might be a potential therapeutic target for chemotherapy resistance. Therefore, this study identifies molecular characteristics that influence the prognosis of breast cancer patients, providing important theoretical insights for the development of personalized treatment strategies.

Objective As important components in the microenvironment of hepatocellular carcinoma(HCC),hepatic stellate cells(HSCs)and hydrogen sulfide(H2S)participate in various biological processes that regulate the development and progression of HCC.Through the co-culture of HSCs and HCC cells,this article aims to investigate the role and mechanism of HSCs in regulating the apoptosis of HCC cells by secreting H2S.Methods The HSC cell line(LX-2)and HCC cell lines(HepG2 and PLC/PRF/5)were used for experiment.RT-qPCR and Western Blot(WB)were used to measure the mRNA and protein expression levels of cystathionine γ-lyase(CSE),a key synthase for H2S;ELISA was used to measure the concentration of H2S in supernatant;next-generation sequencing,cell immunofluorescence assay,chromatin immunoprecipitation(ChIP),and WB were used to measure the JNK/JunB-TNFSF14 signaling pathway genes,binding sites,and related proteins after HepG2 cells were treated by H2S.LX-2 cells were co-cultured with HepG2 or PLC/PRF/5 cells in a Transwell chamber;CCK-8 assay and flow cytometry were used to measure the viability and apoptosis of HCC cells,and WB was used to measure the H2S-TNFSF14 signaling pathway-related proteins.All cell experiments were repeated three times.The independent-samples t test was used for comparison of continuous data between two groups;a one-way analysis of variance or the analysis of variance with repeated measures was used for comparison between multiple groups,and the Dunnett-t test was used for further comparison between two groups.Results LX-2 cells synthesized H2S mainly through CSE,and the concentration of H2S in supernatant of LX-2 cells gradually increased over time(22.89±0.08 pg/mL vs 28.29±0.15 pg/mL vs 36.19±1.90 pg/mL,F=79.63,P<0.05).In LX-2 cells,the mRNA expression level of CSE was significantly higher than that of CBS and MPST(1.008±0.13 vs 0.320±0.014 vs 0.05±0.02,F=80.84,P<0.05).When CSE was inhibited by PPG,the concentration of H2S decreased with the increase in the concentration of PPG(P<0.05).LX-2 cells were co-cultured with HepG2 or PLC/PRF/5 cells,and over the time of culture,there were significant reductions in the viability of HepG2 cells(87.48%±0.82%vs 70.48%±0.641%vs 52.89%±0.57%vs 45.20%±0.69%,F=1 517.13,P<0.001)and PLC/PRF/5 cells(92.41%±0.48%vs 74.10%±0.73%vs 53.70%±0.60%vs 44.00%±0.27%,F=2626.21,P<0.001)and significant increases in the apoptosis of HepG2 cells(12.88%±0.64%vs 15.5%±0.16%vs 18.43%±0.37%vs 13.01%±0.58%,F=142.15,P<0.001)and PLC/PRF/5 cells(8.51±0.05 vs 12.80±0.33 vs 15.59±0.21 vs 10.72±0.30,F=676.40,P<0.001),with the most significant changes on day 3.Next-generation sequencing showed that endogenous H2S and NaHS(endogenous H2S donor)were involved in regulating the expression of various genes in HepG2 cells.By releasing H2S,NaHS and LX2 activated the JNK/JunB signaling pathway and upregulated the expression of the apoptosis gene TNFSF14 in HCC cells,with increased binding between p-JunB and the transcriptional regulatory regions of the TNFSF14 gene.Conclusion In the microenvironment of HCC,HSCs activate the JNK/JunB signaling pathway in HCC cells through the signal molecules CSE/H2S,and there is an increase in the expression of TNFSF14,thereby promoting the apoptosis of HCC cells.

Objective:To analyze the temporal trends of the incidence rate of tuberculosis (TB) in Shaanxi Province and provide a reference for WHO to control the prevalence of TB effectively.Methods:Joinpoint regression was used to analyze the trend of the incidence rate of TB in Shaanxi Province from 2004 to 2022, and the seasonal autoregressive moving average model was used to forecast the incidence rate of TB in Shaanxi Province to 2030.Results:The incidence rate of TB in Shaanxi Province decreased from 90.896/100 000 in 2004 to 35.364/100 000 in 2022, showing a general downward trend (AAPC=-7.72%, P<0.001). From 2014 to 2019, the reduction trend slowed down (APC=-0.69%, P=0.814), of which the largest decline occurred from 2019 to 2022 (APC=-13.26%, P=0.010). The predicted incidence rate of TB in Shaanxi Province from 2020 to 2022 was higher than the reported incidence rate, with the expected incidence rate of 51.342/100 000 in 2022 and 43.468/100 000 in 2030. Conclusion:The incidence rate of TB in Shaanxi Province shows a downward trend from 2004 to 2022, but the decline has shrunk in recent years. It is predicted that the downward trend will continue to slow down by 2030.

Objective To observe the value of propofol combined with etomidate in bariatric surgery based on hemodynamics and stress response.Methods Patients admitted to Shanxi Bethune Hospital who underwent bariatric surgery from January 2020 to January 2021 were retrospectively selected and divided into an experimental group (propofol combined with etomidate) and a control group (propofol) according to the intraoperative anesthesia regimen.The patient's surgical time,awakening time,extubation time,hemodynamic indicators[heart rate (HR),mean arterial pressure (MAP),blood oxygen saturation (SpO2)],stress indicators[adrenocorticotropic hormone (ACTH),adrenaline (ADR),cortisol (COR)],Mini Mental State Examination (MMSE) score,and adverse reactions were recorded.Results A total of 80 patients were included in the study,among which 47 cases were in the experimental group,and 33 cases were in the control group.There was no statistically significant difference in operation time,awakening time and extubation time between the two groups (P>0.05).Immediately after intubation,HR and MAP of the experimental group were lower than those of the control group,and SpO2 was higher than that of the control group (P<0.05).Serum ACTH,ADR and COR levels in the experimental group were higher than those in the control group immediately after intubation and 5 min after extubation (P<0.05).The MMSE score of the experimental group 10 min after awakening was higher than that of the control group (P<0.05).The difference in the incidence of adverse reactions between the two groups was not statistically significant (P>0.05).Conclusion The use of propofol combined with etomidate in weight loss surgery can reduce hemodynamic fluctuations,alleviate cognitive impairment,alleviate stress reactions,and does not significantly increase anesthesia adverse reactions,which is with good safety.
