ObjectiveTo investigate the role and underlying mechanism of the Wnt/β-catenin signaling pathway in the process of Xiaojinwan （XJW）-containing serum interfering with endothelial-mesenchymal transition （EMT） in human breast cancer MDA-MB-231 cells. MethodsXJW-containing serum was prepared by intragastric administration of XJW （4 g·kg^-1） to SD rats. MDA-MB-231 cells were cultured in vitro. β-Catenin overexpression and knockdown plasmids were constructed and transfected into MDA-MB-231 cells. The optimal XJW-containing serum （4 g·kg^-1） according to previous studies was used for β-catenin intervention and overexpression experiments. The groups for intervention/overexpression experiments included intervention/overexpression blank group， β-catenin intervention/overexpression group， intervention/overexpression blank + XJW group， and β-catenin intervention/overexpression + XJW group. Cell morphology was observed under a microscope. Flow cytometry was used to detect and record apoptosis rates. Western blot was performed to measure apoptosis-related proteins ［B-cell lymphoma 2 （Bcl-2）， Bcl-2-associated X protein （Bax）， and active-Caspase-3］ and EMT-related proteins （E-cadherin， N-cadherin， and vimentin）. Real-time polymerase chain reaction （Real-time PCR） was used to detect β-catenin mRNA expression levels in different groups. ResultsIntervention experiment results showed that compared with the intervention blank group， the β-catenin intervention group and the intervention blank + XJW group showed increased apoptosis rates （P<0.05， P<0.01）， elevated protein levels of Bax， active Caspase-3， and E-cadherin （P<0.05， P<0.01）， and decreased protein levels of Bcl-2 and Vimentin （P<0.05， P<0.01）. β-catenin mRNA expression was reduced in the β-catenin intervention group （P<0.05， 0.63 ± 0.15） and the intervention blank + XJW group （P<0.05， 0.79 ± 0.33）. Compared with the β-catenin intervention group， the β-catenin intervention + XJW group exhibited an increased apoptosis rate （P<0.01）， elevated Bax and active Caspase-3 protein levels （P<0.05， P<0.01）， and decreased Bcl-2， N-cadherin， and Vimentin protein levels （P<0.05）. β-catenin mRNA expression was further reduced in the β-catenin intervention + XJW group （P<0.01， 0.22 ± 0.08）. Compared with the intervention blank + XJW group， the β-catenin intervention + XJW group showed an increased apoptosis rate （P<0.01）， elevated Bax， active Caspase-3， and E-cadherin protein levels （P<0.05， P<0.01）， and decreased Bcl-2， N-cadherin， and vimentin protein levels （P<0.05， P<0.01）. β-catenin mRNA expression was also reduced （P<0.05）. Overexpression experiment results showed that compared with the overexpression blank group， the β-catenin overexpression group exhibited a reduced apoptosis rate （P<0.01）， while the overexpression blank + XJW group showed an increased apoptosis rate （P<0.05）. In the β-catenin overexpression and β-catenin overexpression + XJW groups， Bax and E-cadherin protein levels decreased （P<0.05， P<0.01）， while Bcl-2， N-cadherin， and vimentin levels increased （P<0.05）. In the overexpression blank + XJW group， Bax and E-cadherin levels increased （P<0.05， P<0.01）， while Bcl-2， N-cadherin， and vimentin levels decreased （P<0.05， P<0.01）. β-catenin mRNA expression increased in the β-catenin overexpression group （P<0.01， 7.26 ± 1.03） but decreased in the overexpression blank + XJW group （P<0.05， 0.73 ± 0.14）. Compared with the β-catenin overexpression group， the β-catenin overexpression + XJW group showed an increased apoptosis rate （P<0.01）， elevated Bax and E-cadherin levels （P<0.05）， and decreased N-cadherin and vimentin levels （P<0.05）. β-catenin mRNA expression was reduced （P<0.05， 4.65 ± 1.02）. Compared with the overexpression blank + XJW group， the β-catenin overexpression + XJW group exhibited a reduced apoptosis rate （P<0.01）， decreased Bax and E-cadherin levels （P<0.01）， and increased Bcl-2， N-cadherin， and Vimentin levels （P<0.05）. β-catenin mRNA expression increased （P<0.01）. ConclusionXJW-containing serum inhibits breast cancer cell proliferation by suppressing EMT， which is associated with the regulation of the Wnt/β-catenin pathway.

Psychological problems are significant factors that contribute to the occurrence of postoperative complications, reduced quality of life, and prolonged hospital stays. Lung cancer patients who require surgery often experience high psychological stress related to both the disease and the treatment, making them more susceptible to depression and anxiety. Therefore, timely intervention to address these psychological issues is crucial for promoting postoperative recovery and improving patients' quality of life. This paper will review the current status, impact, and interventions for depression and anxiety-related psychological problems in lung cancer surgery patients.

Precancerous lesions of gastric cancer （PLGC） are a group of pathological changes caused by abnormalities in the structure， morphology， and differentiation of gastric mucosal epithelial cells. Since the early symptoms are hidden and non-specific， PLGC is not easy to be diagnosed and it has often developed into intermediate or advanced gastric cancer once being diagnosed and missed the best time for treatment. Accordingly， the incidence of this disease is increasing year by year， which lifts a heavy burden on the patients. The pathogenesis of PLGC is complex， involving inflammatory microenvironment， bile reflux， glycolysis， autophagy， and apoptosis. Currently， PLGC is mainly treated with anti-inflammatory and endoscopic therapies， which are difficult to curb the development of PLGC. Therefore， seeking a safe and effective therapy is an important topic of modern research. Traditional Chinese medicine （TCM）， characterized by treatment based on syndrome differentiation and a holistic view， exerts effects via multiple pathways， mechanisms， and targets. Recent studies have confirmed that TCM can regulate the phosphatidylinositol 3-kinase/protein kinase B/mammalian target of rapamycin （PI3K/Akt/mTOR）， Wnt/β-catenin， Sonic Hedgehog， nuclear factor-κB （NF-κB）， Janus kinase/signal transducer and activator of transcription （JAK/STAT）， hypoxia-inducible factor-1α （HIF-1α）， neurogenic locus notch homolog protein （Notch）， nuclear factor E₂-related factor 2 （Nrf2） and other signaling pathways. By targeting these pathways， TCM can inhibit aerobic glycolysis， reduce oxidative stress， repair the inflammatory microenvironment， regulate cellular autophagy， and promote vascular normalization， thereby delaying or reversing PLGC. However， few researchers have systematically summarized the TCM regulation of PLGC-associated pathways. By reviewing the relevant articles at home and abroad， this paper summarized the roles of the above signaling pathways in the development of PLGC and the research progress in the regulation of signaling pathways by TCM in the treatment of PLGC， with a view to providing a new theoretical basis for the clinical research on PLGC and the drug development for this disease.

Objective:To analyze the drug-resistance pattern and molecular epidemiological characteristics of Enterobacteriales carrying the blaNDM gene in Lishui, aiming to guide clinical anti-infection treatment. Methods:Non-duplicate blaNDM-carrying Enterobacteriales, isolated from Lishui Central Hospital, were collected and identified by VITEK MS. The minimal inhibitory concentrations (MICs) were detected by the broth microdilution method. The ST types of the strains were determined by multilocus sequence typing (MLST). Plasmid types were identified by transformation or conjugation experiments and replication initiator amplification experiments. The transposon structures were detected by PCR amplification. Finally, the epidemic regularity of blaNDM gene in Lishui was analyzed from three levels: clonal group, plasmid, and mobile genetic elements. Results:A total of 109 blaNDM-positive strains were collected. Among them, 60 strains carried the blaNDM-1 gene and 49 strains carried the blaNDM-5 gene. The 109 strains showed 100% resistance to ceftazidime and cefotaxime. The resistance rates to peracillin-tazobactam and imipenem were higher than 80%. Strains carrying the blaNDM-5 gene were more resistant to meropenem than those carrying blaNDM-1 gene( P<0.05). A total of 68 STs were detected from 109 strains, and IncX3, IncFⅡγ, IncA/C and IncT/R plasmids were detected, and 90.83% of the blaNDM genes were located in the IncX3 plasmid. Twelve types of blaNDM gene surrounding structures existed, and they all carried the highly conserved blaNDM- bleMBL- trpF gene sequence. Conclusions:The blaNDM gene has diverse transmission modes in Lishui. The IncX3 plasmid is the main factor mediating its transfer, and all strains carry highly conserved blaNDM- bleMBL- trpF gene sequence.

To report the first case of congenital ichthyosis with woolly hair in China, and to elucidate its genetic variant profile. A 28-year-old female patient presented with rashes on the trunk and limbs for 28 years. Dermatological examination revealed dry and rough skin over the entire body, with well-defined, polygonal, dark brown, adherent scales densely distributed over the trunk and extremities. No significant abnormalities were observed in the mucous membranes, teeth, or nails. The patient exhibited uniformly distributed, woolly and curly hair with a soft, dry texture and normal density; no significant hair breakage or brittleness was observed, while the eyebrows appeared sparse. Hair microscopy showed irregular axial twisting of hair strands at varying intervals; scanning electron microscopy (SEM) revealed irregular hair shafts with some segments appearing flat in a belt-like pattern, and magnified SEM images further demonstrated hair cuticle damage on the surface of hair shafts, manifesting as localized upward curling and longitudinal grooves, indicating structural damage to the hair shafts. Whole-exome sequencing identified a homozygous variant c.124dupC in exon 3 of the PRSS8 gene in the proband, resulting in a frameshift mutation (p.Gln42Profs*24) in the PRSS8 protein. According to the guidelines of the American College of Medical Genetics and Genomics as well as the patient's clinical manifestations, this variant could be preliminarily classified as pathogenic. A diagnosis of syndromic ichthyosis was made. This case represents the first report of syndromic ichthyosis caused by PRSS8 variants in China and the second report in the world, and this condition is proposed to be tentatively named as "ichthyosis-woolly hair syndrome".

Objective:To investigate the association between blood pressure variability (BPV) and all-cause mortality and cardiovascular events in patients undergoing continuous ambulatory peritoneal dialysis (CAPD), and provide reference for clinical management in CAPD patients.Methods:This retrospective cohort study included patients who received CAPD at Guangdong Provincial People's Hospital between May 1, 2010, and July 31, 2023. Baseline and clinical data of the patients were collected. Coefficient of variation of systolic blood pressure (CVSBP) was used to assess BPV. The patients were divided into CVSBP T1, CVSBP T2 and CVSBP T3 groups based on CVSBP tertiles, and the differences among the three groups were compared. Diastolic blood pressure and mean arterial pressure were used to further assess BPV and sensitivity analysis was conducted. The primary endpoint was the composite outcome of all-cause mortality and cardiovascular events. Kaplan-Meier survival curve and Cox regression analysis were used to analyze the association between CVSBP and the primary endpoint.Results:A total of 358 CAPD patients were included, with age of (43.6±13.3) years, and 197 males (55.0%). The proportion of males, proportion of smoking, baseline blood urea nitrogen, serum creatinine and serum albumin in CVSBP T2 (9.08%≤CVSBP<12.55%, n=120) group and CVSBP T3 (CVSBP≥12.55%, n=119) group were lower than those in CVSBP T1 group (CVSBP<9.08%, n=119), and baseline systolic blood pressure, residual kidney Kt/V and total Kt/V were higher than those in CVSBP T1 group, with statistically significant difference among the three groups (all P<0.05). During follow-up of 37(23, 76) months, 49 patients (13.7%) experienced the composite endpoint events, including 12 patients (3.4%) of all-cause deaths and 42 patients (11.7%) of cardiovascular events. Kaplan-Meier survival analysis showed that the incidence of composite endpoint events in CVSBP T3 group was higher than that in CVSBP T1 group and CVSBP T2 group, but the difference was not statistically significant (Log-rank χ2=3.795, P=0.150). Multivariate Cox regression analysis showed that, after adjusting for age, sex, diabetes, baseline systolic blood pressure, residual renal function, and serum albumin, as a continuous variable, CVSBP was not associated with the risk of composite outcome in CAPD patients ( HR=1.058, 95% CI 0.985?1.135, P=0.122); as a categorical variable, with CVSBP T1 group as reference, CVSBP T2 group and CVSBP T3 group were not associated with the risk of composite outcome ( HR=1.222, 95% CI 0.471?3.167, P=0.681; HR=1.827, 95% CI 0.737?4.530, P=0.193). The sensitivity analysis showed that increased variability of diastolic blood pressure ( HR=1.162, 95% CI 1.063?1.270, P=0.021) and increased variability of mean arterial pressure ( HR=1.114, 95% CI 1.030?1.204, P=0.007) were correlated with higher risk of composite outcome in CPAD patients. Conclusions:Systolic blood pressure variability during follow-up is not associated with risk of composite outcome of all-cause mortality and cardiovascular events in CAPD patients. Increased variability of diastolic blood pressure and increased variability of mean arterial pressure are associated with a higher risk of composite outcome in CPAD patients. Interventions to reduce BPV may be helpful to improve the long-term prognosis of CAPD patients.

Objective To conduct preliminary evaluation of the reliability and safety of pancreatic duct-to-jejunum stent-bridging internal drainage as a supplementary approach to pancreaticojejunostomy in central pancreatectomy.Methods The clinical data of 28 patients who underwent robotic central pancreatectomy performed by our team between January 2021 and November 2024 were retrospectively collected,and and follow-up of postoperative endocrine and exocrine functions was performed.Based on the methods of digestive tract reconstruction adopted,the patients were divided into a conventional pancreaticojejunostomy group and a pancreatic duct-to-jejunum stent-bridging internal drainage group(PancreaticoJejunal-Stent bridge group).The operative time,digestive tract reconstruction time,and short-term complications were compared between the two groups.Results Among patients undergoing robotic central pancreatectomy,the digestive tract reconstruction time was shorter(t=5.168,P<0.001)in the PancreaticoJejunal-Stent bridge group([31.1±6.3]min)than that in the conventional pancreaticojejunostomy group([49.7±8.9]min)(t=5.168,P<0.001).The total operative time was(172.7±64.6)min in the PancreaticoJejunal-Stent bridge group and(200.1±52.7)min in the conventional pancreaticojejunostomy group,showing no statistically significant difference(t=1.215,P=0.235).In the PancreaticoJejunal-Stent bridge group,one patient developed a postoperative biochemical fistula,and 14 patients developed grade B pancreatic fistulas.Among the 14 patients with grade B pancreatic fistulas,1 case was complicated by fistula-related intra-abdominal infection,and 13 cases had drainage tube retention time of more than 21 days.In the conventional pancreaticojejunostomy group,2 patients developed postoperative biochemical fistulas,and 11 patients developed grade B pancreatic fistulas.Among the 11 patients with grade B pancreatic fistulas,1 case was complicated by fistula-related intra-abdominal infection,and 1 case was complicated by fistula-related intra-abdominal bleeding and infection.No postoperative gastroparesis,pancreatitis,or grade C pancreatic fistulas occurred in either group.There were no statistically significant differences between the two groups in overall postoperative complication rate(P=0.522),postoperative pancreatic fistula rate(P=0.583),intra-abdominal infection rate(P=0.583),or bleeding rate(P=0.464).Conclusion Pancreatic duct-to-jejunum stent-bridging internal drainage optimizes the anastomosis between the distal end of the pancreas and the jejunum during central pancreatectomy,shortens digestive tract reconstruction time,and reduces surgical complexity without increasing the risk of short-term severe postoperative complications.This approach is safe and feasible.

Objectives:To investigate the clinical efficacy of robot-assisted(RA)unilateral biportal endoscopic lumbar interbody fusion(UBE-LIF)in the treatment of single-level lumbar spinal stenosis(LSS).Methods:A retrospective analysis was conducted on the clinical data of 90 patients with LSS admitted to the Spine De-partment of Foshan Hospital of Traditional Chinese Medicine from August 2023 to February 2024.The pa-tients were divided into an observation group(42 patients,treated with RA-UBE-LIF)and a control group(48 patients,treated with UBE-LIF).The patients' baseline information and clinical data were collected,including age,gender,duration of illness,and lesion segments.The number of fluoroscopic exposures,operative time,intraoperative blood loss,postoperative drainage volume,length of hospital stay,screw placement accuracy(based on the Gertzbein criteria),and the occurrence of complications were compared between the two groups.The visual analogue scale(VAS)score and Oswestry disability index(ODI)were used to quantitatively assess the improvement in back and leg pain and the recovery of lumbar function in patients before surgery and at 1 week,3 months,and 6 months postoperatively.Results:All the patients successfully completed the surgery and were followed up for a period ranging from 6 to 12 months.Compared with the control group,the obser-vation group had significantly fewer fluoroscopic exposures(4.40±0.83 vs 9.92±1.62),less intraoperative blood loss(90.76±13.27mL vs 121.21±16.75mL),postoperative drainage volume(75.93±14.43mL vs 93.02±17.04mL),and length of hospital stay(4.43±1.52d vs 7.19±1.79d)(all P＜0.05).There was no significant difference in oper-ative time between the two groups(118.24±8.91min vs 120.67±10.43min)(P＞0.05).The accuracy rate of RA percutaneous screw placement in the observation group was 97.62％,which was significantly different from that of the control group(89.58％)(P＜0.05).The complication rate in the observation group was 2.38％,which was not significantly different from that of the control group(6.25％)(P＞0.05).The VAS scores for back and leg pain and ODI of both groups at each postoperative time point were significantly lower than those at the previ-ous time point(P＜0.05).There were no significant differences between the two groups preoperatively(P＞0.05),but the improvements in VAS scores and ODI at each postoperative time point(1 week,3 months,6 months)were better in the observation group compared to the control group(P＜0.05).Conclusions:Orthopedic RA-UBE-LIF for the treatment of LSS is accurate and safe,which has satisfactory therapeutic effects.

Energy metabolism reprogramming is one of the pathological mechanisms involved in the occurrence and development of tumors.This article focused on the theory of spleen deficiency in TCM and energy metabolism reprogramming to elaborate the pathological mechanism of tumors.TCM believes that spleen deficiency is an important organ pathogenesis that causes cancer due to deficiency,and spleen deficiency runs through the occurrence and development of tumors.The spleen is the source of qi and blood transformation and dominates the energy metabolism of the whole body.Mitochondria are the regulatory center of energy metabolism in the body,and abnormal mitochondrial energy metabolism is the manifestation of spleen deficiency at the cellular micro level,which is mainly manifested as the limitation of mitochondrial oxidative phosphorylation and the conversion to aerobic glycolysis to provide energy for the rapid growth of tumors.Therefore,based on the theory of spleen deficiency,the treatment based on spleen strengthening is used to prevent and treat tumors by improving energy metabolism,which not only enriches the modern medical connotation of spleen deficiency in TCM,but also provides a new perspective for TCM to treat malignant tumors from the perspective of spleen strengthening.
