Objective To investigate the setup error in patients with spinal bone metastasis who underwent radiotherapy under the guidance of kilovoltage cone-beam CT (KV-CBCT). Methods A total of 118 patients with spinal metastasis who underwent radiotherapy, including 17 cases of cervical spine, 62 cases of thoracic spine, and 39 cases of lumbar spine, were collected. KV-CBCT scans were performed using the linear accelerators from Elekta and Varian’s EDGE system. CBCT images were registered with reference CT images in the bone window mode. A total of 973 data were collected, and 3D linear errors were recorded. Results The patients with spinal bone metastasis were grouped by site, height, weight, and BMI. The P value of the patients grouped only by site was P<0.05, which was statistically significant. Conclusion When grouped by site in the 3D direction, the positioning effect of cervical spine is better than that of thoracic and lumbar spine. The positioning effect of the thoracic spine is better in the head and foot direction but worse in the left and right direction compared with that of the lumbar spine. Instead of extending or narrowing the margin according to the BMI of patients with spinal metastasis, the margin must be changed according to the site of spinal bone metastasis.

ObjectiveTo investigate the influencing factors for traditional Chinese medicine (TCM) syndromes of primary liver cancer, and to provide a theoretical basis for the TCM syndrome differentiation and standardized treatment of liver cancer. MethodsTCM syndrome differentiation was performed for 415 patients who were admitted to Shanxi Institute of Traditional Chinese Medicine and were diagnosed with primary liver cancer based on pathological or clinical examinations from January 2019 to December 2023. The chi-square test was used for comparison of categorical data between groups, and the unordered polytomous logistic regression model was used to investigate the influencing factors for TCM syndromes of liver cancer. ResultsThe common initial symptoms of the 415 patients with primary liver cancer included pain in the liver area (31.81%), abdominal distension (25.30%), abdominal pain (15.18%), and weakness (13.98%), and the main clinical symptoms included poor appetite (70.84%), fatigue (69.16%), pain in the liver area (67.47%), poor sleep (59.04%), abdominal distension (53.01%), and constipation (52.53%). There were significant differences in TCM syndromes between patients with different sexes, courses of the disease, clinical stages, Child-Pugh classes, presence or absence of intrahepatic and extrahepatic metastasis, and presence or absence of transcatheter arterial chemoembolization (TACE) and radiofrequency ablation (all P<0.05). The logistic regression analysis showed that male sex was a risk factor for damp-heat accumulation (odds ratio [OR]=2.036, P=0.048) and the syndrome of spleen-kidney Yang deficiency (OR=5.240, P<0.001); a course of disease of<1 year was a risk factor for damp-heat accumulation (OR=2.837, P=0.004) and syndrome of Qi stagnation and blood stasis (OR=2.317, P=0.021), but it was a protective factor against syndrome of spleen-kidney Yang deficiency (OR=0.385, P=0.005); Child-Pugh class A/B was a protective factor against liver-kidney Yin deficiency (OR=0.079, P<0.001); intrahepatic metastasis was a risk factor for liver-kidney Yin deficiency (OR=5.117, P=0.003) and syndrome of spleen-kidney Yang deficiency (OR=3.303, P=0.010); TACE was a protective factor against liver-kidney Yin deficiency (OR=0.171, P<0.001) and syndrome of spleen-kidney Yang deficiency (OR=0.138, P<0.001); radiofrequency ablation was a risk factor for damp-heat accumulation (OR=4.408, P<0.001) and liver-kidney Yin deficiency (OR=32.036, P<0.001). ConclusionSex, course of disease, Child-Pugh class, intrahepatic metastasis, TACE, and radiofrequency ablation are the main influencing factors for TCM syndromes of liver cancer.

ObjectiveTo explore the potential mechanism by which Huangqi Baijiang Yiren decoction (HBY) repairs the intestinal mucosal injury in the rat model of ulcerative colitis (UC) via the miR-21/suppressor of cytokine signaling 1 (SOCS1)/Janus kinase 1 (JAK1)/signal transducer and activator of transcription 6 (STAT6) signaling pathway. MethodsSixty SPF-grade male SD rats were randomly assigned into six groups: blank, model, low-dose (3.68 g·kg-1) HBY, medium-dose (7.35 g·kg-1) HBY, high-dose (14.5 g·kg-1) HBY, and mesalazine (0.035 g·kg-1), with 10 rats in each group. The rat model of UC was established in other groups except the blank group by 3% dextran sulfate sodium solution. The rats were administrated with corresponding drugs once a day for 7 consecutive days since the 3th day after modeling. The histopathological changes of the colon were observed by hematoxylin-eosin staining, and the Robarts histopathology index (RHI) was scored. Enzyme-linked immunosorbent assay was employed to measure the levels of pro-inflammatory cytokines [interleukin (IL)-6, IL-18, IL-1β, and tumor necrosis factor-α (TNF-α)] in the serum. Real-time PCR was employed to determine the mRNA levels of miR-21, SOCS1, JAK1, and STAT6 in the colon tissue. Western blot was employed to determine the protein levels of SOCS1, JAK1, phosphorylated (p)-JAK1, STAT6, p-STAT6, Occludin, and Claudin-1 in the colon tissue. ResultsCompared with the blank group, the model group showed an increase in disease activity index (DAI) (P<0.01), shortening of colon length (P<0.01), severe histopathological damage in the colon tissue, and an increase in RHI, rises in serum levels of IL-6, IL-1β, IL-18, and TNF-α (P<0.01), up-regulation in mRNA levels of miR-21, JAK1, and STAT6 and protein levels of p-JAK1 and p-STAT6 (P<0.01), and down-regulation in mRNA and protein levels of SOCS1 and protein levels of Occludin and Claudin-1 (P<0.01). The treatment with HBY reduced the DAI (P<0.01), alleviated colon shortening and histopathological damage in the colon tissue, decreased the RHI (P<0.01), lowered the serum levels of IL-6, IL-1β, IL-18, and TNF-α (P<0.01), down-regulated the mRNA levels of miR-21, JAK1, and STAT6 (P<0.05, P<0.01), up-regulated the mRNA level of SOCS1 (P<0.05), up-regulated the protein levels of SOCS1, Occludin, and Claudin-1 (P<0.05, P<0.01), and down-regulated the protein levels of p-JAK1 and p-STAT6 (P<0.05, P<0.01). ConclusionHBY may modulate the miR-21/SOCS1/JAK1/STAT6 signaling pathway to suppress inflammatory responses and restore the intestinal mucosal barrier in UC rats.

Cognitive impairment (CI) is a clinical syndrome characterized by progressive decline in advanced cognitive functions such as memory, thinking, and judgment. Its etiology and pathogenesis are complex, and there is currently a lack of specific drug interventions. Metformin, as a first-line hypoglycemic drug for type 2 diabetes, not only lowers blood glucose levels but also improves CI. This article reviews and summarizes the pharmacological effects and mechanisms of metformin in improving Alzheimer’s disease, diabetes cognitive impairment, cognitive impairment after chemotherapy, in order to provide novel insights and approaches for the treatment of CI-related diseases. Studies have shown that the mechanism by which MET intervenes in CI mainly includes regulating β-amyloid protein and tau protein metabolism, reducing insulin resistance, inhibiting neuroinflammation, improving synaptic plasticity, improving mitochondrial dysfunction, regulating gut microbiota and lipid metabolism, etc. Future research needs to be conducted through interdisciplinary collaboration, fully integrating multiple omics data, and combining advanced technologies to further reveal their mechanisms of effect.

Background::Pancreatic ductal adenocarcinoma (PDAC) is one of the main types of malignant tumor of the digestive system, and patient prognosis is affected by difficulties in early diagnosis, poor treatment response, and a high postoperative recurrence rate. Carbohydrate antigen 19-9 (CA19-9) has been widely used as a biomarker for the diagnosis and postoperative follow-up of PDAC patients. Nevertheless, the production mechanism and potential role of CA19-9 in PDAC progression have not yet been elucidated.Methods::We performed single-cell RNA sequencing on six samples pathologically diagnosed as PDAC (three CA19-9-positive and three CA19-9-negative PDAC samples) and two paracarcinoma samples. We also downloaded and integrated PDAC samples (each from three CA19-9-positive and CA19-9-negative patients) from an online database. The dynamics of the proportion and potential function of each cell type were verified through immunofluorescence. Moreover, we built an in vitro coculture cellular model to confirm the potential function of CA19-9. Results::Three subtypes of cancer cells with a high ability to produce CA19-9 were identified by the markers TOP2A, AQP5, and MUC5AC. CA19-9 production bypass was discovered on antigen-presenting cancer-associated fibroblasts (apCAFs). Importantly, the proportion of immature ficolin-1 positive (FCN1+) macrophages was high in the CA19-9-negative group, and the proportion of mature M2-like macrophages was high in the CA19-9-positive group. High proportions of these two macrophage subtypes were associated with an unfavourable clinical prognosis. Further experiments indicated that CA19-9 could facilitate the transformation of M0 macrophages into M2 macrophages in the tumor microenvironment. Conclusions::Our study described CA19-9 production at single-cell resolution and the dynamics of the immune atlas in CA19-9-positive and CA19-9-negative PDAC. CA19-9 could promote M2 polarization of macrophage in the pancreatic tumor microenvironment.

AIM:To investigate the effect of plate-let(PLT)on angiogenesis in hepatocellular carcino-ma and the intervention effect of Cinobufagin(CBG).METHODS:Firstly,we screened the suitable co-incubation ratio of PLT and hepatocellular carci-noma cells,prepared conditioned medium,and de-termined the half inhibitory concentration of Cinob-ufagin;then,we set up a control group(human um-bilical vein endothelial cells(EC)+conventional me-dium),a crosstalk group(EC+CM_HP(strip culture prepared by crosstalk of HUH7 and PLT)),and an in-tervention group(EC+CM_HP+CBG).The migration,tube-formation and sprouting capacity of EC and the level of vascular endothelial growth factor(VEGF)in co-cultured supernatant were evaluated by scratch assay,tube-formation assay,budding as-say and ELISA assay.Western blot was used to de-tect the expression of VEGFR2 and p-VEGFR2,and reverse verification was performed with inhibitors.A subcutaneous transplantation tumour model of hepatocellular carcinoma in nude mice was estab-lished,with Model group,Model+CBG group and Model+Apa group.The collagen expression of the transplantation tumour was observed by Masson staining,and the expression levels of vascular endo-thelial markers CD31 and CD34 were detected by immunofluorescence.RESULTS:When PLT:HUH7=200,the activity of HUH7 was the strongest,and the crosstalk between HUH7 and PLT significantly promoted the proliferation of EC(P<0.01).Com-pared with Control group,the migration,tube-for-mation and budding ability of Crosstalk group were enhanced,and those of Intervention group were lower than those of Crosstalk group(P<0.01).The expression level of VEGF in the supernatant of Crosstalk group was higher than that of Control group,while that of Intervention group was lower than that of Crosstalk group(P<0.01).The expres-sion level of p-VEGFR2 protein in Crosstalk group was significantly higher than that of Control group,but the expression level of Intervention group was lower than that of Crosstalk group(P<0.01).Large collagen fibre deposition was seen in the Model group,and CBG intervention significantly reduced collagen fibre deposition in the transplanted tu-mour tissues.CD31 and CD34 expression was pres-ent in the hepatocellular carcinoma transplanted tumour tissues in the Model group,and CBG inter-vention significantly reduced the expression of CD31 and CD34 in the liver cancer transplanted tu-mour tissues(P<0.01).CONCLUSION:PLT enhances angiogenesis in hepatocellular carcinoma,and CBG may inhibit its tube-forming ability via the VEGF/VEGFR2 pathway.

Objective:To explore the efficacy and safety of sirolimus in the treatment of diazoxide unresponsive congenital hyperinsulinism(CHI) and summarize the single-center experience.Methods:A retrospective analysis was conducted on the clinical data of 5 cases of CHI treated with sirolimus after ineffective treatment with diazoxide, admitted to the Children′s Hospital Affiliated to Zhengzhou University from January 2017 to December 2022. The efficacy and safety of sirolimus in the treatment of CHI were evaluated.Results:The study included 5 patients, 3 males and 2 females. The age of onset ranged from 1 to 90 days. Initial symptoms included poor mental state(2/5) and convulsions(3/5). Blood glucose levels were 1.1 to 2.3 mmol/L, and insulin levels ranged from 13.52 to 70.53 μIU/mL. Two cases were classified as diffuse type, and the histological type of 3 cases was unknown. Genetic testing confirmed the diagnosis, with whole-exome sequencing revealing an unreported novel mutation in 1 case(ABCC8 exon 25_28del). Of the five patients, three patients were treated with sirolimus after diazoxide and octreotide failed, one patient was treated after unresponsive diazoxide, and the other one was treated after diazoxide, octreotide, and even near-total pancreatectomy failed. The onset age of sirolimus therapy ranged from 1 to 20 months. The maximum dosage of sirolimus was 1.2-3.2 mg·m -2·d -1, and the duration of medication ranged from 2 to 12 months. One patient was fully responsive to sirolimus, and the other four patients were partially responsive. All patients achieved euglycemia with sirolimus alone or in combination with standard CHI treatment. During follow-up, non-infectious diarrhea, elevated carcinoembryonic antigen, elevated triglycerides, and elevated liver enzymes were observed. Conclusion:This study indicates that sirolimus has a certain degree of efficacy in CHI patients for whom diazoxide treatment is ineffective. However, the long-term efficacy and safety warrant further multicenter trials.
