Malignant tumor metastasis is the key factor leading to poor prognosis of patients， and it is a difficult problem to be overcome in the field of tumor therapy. Metabolic reprogramming， as a key link in the regulation of tumor metastasis activity， affects the growth， invasion， and metastasis of tumor cells by changing the metabolic pathways of intracellular substances （such as glucose， amino acids， lipids， and nucleotides）. In particular， metabolic reprogramming plays a key role in the multistage linked steps related to tumor metastasis and can play a crucial role in several key stages of tumor tissue dissociation in situ， hematogenous metastasis， and remote colonization. Malignant tumor cells can selectively adjust their own metabolic state to adapt to the growth conditions of different metastatic microenvironments and colonization sites and then choose the most favorable growth and metabolism strategy. According to the holistic concept of traditional Chinese medicine （TCM）， the metastasis of malignant tumors is generally closely related to the metabolic state of the whole body. One of the advantages of TCM in the treatment of malignant tumors is systemic regulation. With its multi-pathway， multi-target， and multi-component therapeutic characteristics， TCM can effectively control the metastasis of malignant tumors by regulating the degradation of tumor epithelial mesenchymal transformation （EMT） and extracellular matrix （ECM）， anchoring the independent growth of tumor cells and the tumor microenvironment. In this paper， the potential regulatory effects of metabolic reprogramming on the metastasis of malignant tumors were discussed， and the latest research progress of the regulation of metabolic reprogramming by TCM on tumor metastasis was reviewed. At the same time， the key targets of TCM and its bioactive components in the process of tumor metastasis intervention were reviewed. This study aims to provide a more valuable basis and clearer idea for the treatment of malignant tumor metastasis by regulating metabolic reprogramming with TCM.

[Objective] To compare the clinical efficacy of super pulse thulium laser enucleation of the prostate (SPThuLEP) with "open tunnel" and transurethral holmium laser enucleation of the prostate (HoLEP) in the treatment of benign prostatic hyperplasia (BPH), in order to provide reference for the treatment options of BPH. [Methods] The clinical data of 112 BPH patients treated in our hospital during Jan.2023 and Jul.2023 were retrospectively analyzed, including 65 treated with SPThuLEP with "open tunnel" and 57 with HoLEP.The operation time, postoperative hemoglobin decrease, postoperative bladder irrigation, catheter indwelling time, hospitalization time and complications were compared between the two groups.The changes of maximum urine flow rate (Qmax), international prostate symptom score (IPSS), quality of life score (QoL), postvoid residual (PVR) and prostate-specific antigen (PSA) were compared between the two groups before operation and one month after operation. [Results] All operations were successful without conversion to open or transurethral plasmakinetic resection.The postoperative decrease of hemoglobin in SPThuLEP group was lower than that in HoLEP group [(13.12±6.72) g/L vs. (21.02±6.51) g/L], with statistical difference (P<0.05). There were no significant differences in the operation time [(63.35±15.73) min vs.(61.02±17.55) min], postoperative bladder irrigation time [(1.07±0.45) d vs. (1.06±0.36) d], catheter indwelling time [(2.98±0.56) d vs. (3.01±0.63) d] and hospitalization time [(3.63±0.61) d vs.(3.79±0.76) d] between the two groups (P>0.05). No blood transfusion, secondary bleeding or unplanned hospitalization occurred, and there were no serious complications such as transurethral electroresection syndrome (TURS), urethral stricture and urinary incontinence.One month after operation, the Qmax, IPSS, QoL, PVR and PSA of the two groups were significantly improved compared with those before operation (P<0.05), but with no statistical difference between the two groups (P>0.05). [Conclusion] SPThuLEP with "open tunnel" has comparable efficacy as HoLEP in the treatment of BPH.With advantages of small amount of bleeding and high safety, this minimally invasive technique can be widely popularized in clinical practice.

ObjectiveTo investigate the current status of latent tuberculosis infection (LTBI) among the elderly population in rural areas of Changxing County, Zhejiang Province, and to provide an evidence for the development of LTBI prevention and control measures. MethodsBetween January and May 2024, elderly individuals participating in urban and rural residents’ health checkups were screened for Mycobacterium tuberculosis infection using a domestically produced interferon-γ release assay (IGRA) kit. Individuals tested positive by IGRA but without active tuberculosis were classified as LTBI cases. The prevalence of LTBI among the participants was subsequently analyzed. ResultsAmong the 6 765 subjects, 637 tested positive by IGRA, including one identified active tuberculosis patient, resulting in a LTBI prevalence rate of 9.40%. There was a statistically significant difference in positivity rates across different IGRA methodologies (χ²=35.530, P<0.001). Higher LTBI rate was observed in males, individuals with a history of diabetes mellitus, and those with a history of pulmonary tuberculosis, exhibiting statistically significant differences (χ²=32.401, P<0.001; χ²=5.789, P=0.020; χ²=39.248, P<0.001, respectively.) No statistically significant difference in LTBI rate was found across different age groups (χ²=0.238, P=0.971). ConclusionThe prevalence of LTBI among the elderly rural residents in Changxing County is relatively low. Male, individuals with a history of diabetes mellitus, and those with a history of pulmonary tuberculosis have an increased risk of LTBI, warranting targeted risk monitoring and timely interventions.

ObjectiveTo explore the effect of Tanreqing injection combined with Ceftazide on the clinical efficacy， lung function， and laboratory inflammatory index of patients suffering from phlegm heat obstructing lung syndrome in acute exacerbation of chronic obstructive pulmonary disease （AECOPD）. MethodFrom June 2021 to June 2023， 76 patients diagnosed with phlegm heat obstructing lung syndrome in AECOPD were enrolled in the respiratory and critical medical department of Jieshou Hospital of Traditional Chinese Medicine. They were randomly divided into a control group and an observation group with 38 cases each. The control group used Ceftazidime intravenous drip and other conventional oxygen inhalation and antispasmodic treatment measures of western medicine. The observation group received Tanreqing injection intravenous drip based on the treatment of the control group， with a course of 10 days. The changes of laboratory indicators such as hs-CRP， calcitonin （PCT）， and interleukin-6 （IL-6） before and after treatment were analyzed， and the improvement of forced expiratory volume in the first second （FEV₁）， forced vital capacity （FVC）， one second rate （FEV₁/FVC）， assessment and improvement of the British Medical Research Society’s dyspnea index （mMRC）， self-evaluation test of chronic obstructive pulmonary disease patients （CAT）， and traditional Chinese medicine syndrome score was compared. In addition， the total effective rate between the two groups after treatment was compared. ResultAfter treatment， the hs-CRP， PCT， IL-6， FEV₁， FVC， FEV₁/FVC， mMRC， CAT scores， and traditional Chinese medicine syndrome evaluation of both groups improved （P<0.01）. After treatment， compared with the control group， the observation group showed more significant improvements in hs-CRP， PCT， IL-6， FEV₁， FVC， FEV₁/FVC， mMRC， CAT scores， and traditional Chinese medicine syndrome evaluation， and the difference was statistically significant （P<0.05，P<0.01）. The total clinical effective rate of the control group was 86.84% （33/38）， while that of the observation group was 94.74% （36/38）. The therapeutic effect of the observation group was better than that of the control group （χ²=8.471， P<0.05）. ConclusionTanreqing injection combined with Ceftazidime has obvious efficacy in the treatment of phlegm heat obstructing lung syndrome in AECOPD， which is better than the treatment of Ceftazidime antibiotics alone. It can reduce the risk of acute exacerbation， alleviate clinical symptoms， and delay the decline of lung function.

Objective To explore the application value of vesicourethral anastomosis with maximal urethral length preservation(MULP)and bladder neck preservation(BNP)in laparoscopic radical prostatectomy(LRP)or robot-assisted laparoscopic radical prostatectomy(RALP)for high-risk prostate cancer(HRPC)in terms of early urinary continence and oncology.Methods Clinical data of 23 HRPC patients who underwent LRP(including RALP)with MULP and BNP in our hospital during May 2022 and Jan.2024 were retrospectively analyzed.Patients'basic information,surgical parameters,postoperative complications,oncological outcomes and urinary incontinence were collected and analyzed.Results All operations were completed successfully without conversion to open surgery.The operation time was(108±31)min,average blood loss(112±45)mL,hospital stay(5.5±1.5)days,urethral catheterization time(12.6±1.8)days,and no patient received blood transfusion during operation.The urinary continence rates at the time of catheter removal,and at 1,3,and 6 months after surgery were 39.1％,65.2％,73.9％,and 91.3％,respectively.Two patients had positive margins,both of which were at the neurovascular bundle.No patient developed surgery-related complications,urinary obstruction or fistula after surgery.Conclusion Vesicourethral anastomosis with MULP and BNP in LRP for HRPC can effectively improve patients'early urinary continence rate and postoperative quality of life without increasing the oncological risk.

Objective To study the effect of MT-1207 on blood glucose,blood lipids and atherosclerosis in mice.Methods The apolipoprotein E knockout(ApoE-/-)mice were fed with normal feed,drug feed containing losartan and drug feed containing MT-1207 at a dosage of 30 mg/kg.The body weight,blood glucose and blood lipids were detected,and the plaque area of atherosclerotic was evaluated.8-week-old male C57 mice were fed a high fat diet and given intragastric administration of MT-1207 and losartan at a dose of 30 mg/kg per day.The body weight,blood glucose and lipids levels were also examined to further evaluate the effects of MT-1207 on blood glucose and lipids levels.Results ApoE-/-mice treated with MT-1207 and losartan gained weight faster.There was no significant improvement in blood glucose and lipid levels,and no significant change in atherosclerotic plaque area.MT-1207 and losartan had no significant improvement effect on blood glucose and blood lipids of C57 mice.Conclusion MT-1207 and losartan couldn't improve the levels of blood glucose,blood lipids and atherosclerosis,and couldn't aggravate atherosclerosis.

Objective To explore the correlation of molecular pathological grading with WHO grade 1 meningioma recurrence,malignant progression,and patients'survival.Methods The medical records and paraffin-embedded tissues of patients with surgically resected WHO grade 1 meningioma were collected.The molecular pathological risk grading suggested by Maas et al.was adopted,and the patients were graded as low,intermediate,and high risk.Univariate log-rank test and multivariate Cox regression analyses were performed to determine the relationship between molecular risk grading and patient progression-free survival(PFS),malignant progression-free survival(MPFS),and overall survival(OS).Results Among 198 patients,152(76.8%)were graded as low risk,showing no 1p deletion;42(21.2%)patients were graded as intermediate risk,including 18 patients with 1p deletion,10 patients with 1p combined with 6q deletion,and 14 patients with 1p combined with 14q deletion;and 4(2%)patients were graded as high risk,including two patients with TERT promoter mutation,one patient with CDKN2A/B homozygous deletion,and one patient with 1p,6p,and 14q combined deletion.Multivariate analysis showed that molecular risk grading was negatively associated with PFS(HR:0.029,95%CI:0.011-0.080),MPFS(HR:0.032,95%CI:0.004-0.274),and OS(HR:0.074,95%CI:0.032-0.174;P<0.05).Conclusion The biological behavior of histological grade 1 meningiomas still exhibits heterogeneity,and further molecular pathological risk grading can more accurately reflect their biological behavior and evaluate patient prognosis.

Background::Hypothermia therapy has been suggested to attenuate myocardial necrosis; however, the clinical implementation as a valid therapeutic strategy has failed, and new approaches are needed to translate into clinical applications. This study aimed to assess the feasibility, safety, and efficacy of a novel selective intracoronary hypothermia (SICH) device in mitigating myocardial reperfusion injury.Methods::This study comprised two phases. The first phase of the SICH was performed in a normal porcine model for 30 minutes ( n = 5) to evaluate its feasibility. The second phase was conducted in a porcine myocardial infarction (MI) model of myocardial ischemia/reperfusion which was performed by balloon occlusion of the left anterior descending coronary artery for 60 minutes and maintained for 42 days. Pigs in the hypothermia group ( n = 8) received hypothermia intervention onset reperfusion for 30 minutes and controls ( n = 8) received no intervention. All animals were followed for 42 days. Cardiac magnetic resonance analysis (five and 42 days post-MI) and a series of biomarkers/histological studies were performed. Results::The average time to lower temperatures to a steady state was 4.8 ± 0.8 s. SICH had no impact on blood pressure or heart rate and was safely performed without complications by using a 3.9 F catheter. Interleukin-6 (IL-6), tumor necrosis factor-α, C-reactive protein (CRP), and brain natriuretic peptide (BNP) were lower at 60 min post perfusion in pigs that underwent SICH as compared with the control group. On day 5 post MI/R, edema, intramyocardial hemorrhage, and microvascular obstruction were reduced in the hypothermia group. On day 42 post MI/R, the infarct size, IL-6, CRP, BNP, and matrix metalloproteinase-9 were reduced, and the ejection fraction was improved in pigs that underwent SICH.Conclusions::The SICH device safely and effectively reduced the infarct size and improved heart function in a pig model of MI/R. These beneficial effects indicate the clinical potential of SICH for treatment of myocardial reperfusion injury.

Objective To investigate the expression of OTU deubiquitinase 3(OTUD3)and interleukin en-hancer binding factor 2(ILF2)in esophageal squamous cell cancer and their correlation with clinicopathologi-cal characteristics and prognosis.Methods A total of 102 patients with esophageal squamous cell cancer who underwent radical resection in Huai'an Fifth People's Hospital between January 2019 and July 2020 were in-cluded in this study.Immunohistochemistry was used to detect OTUD3 and ILF2 expression.Spearman rank correlation analysis was conducted to assess the relationship between OTUD3 and ILF2.Kaplan-Meier surviv-al curves were used to analyze the impact of OTUD3 and ILF2 expression on patient survival prognosis.COX regression analysis was employed to identify prognostic factors.Results Compared with adjacent tissues,the positive rate of OTUD3 was lower and the positive rate of ILF2 was higher in esophageal squamous cell cancer tissues,and the differences were statistically significant(P＜0.05).A significant negative correlation was ob-served between the expression of OTUD3 and ILF2 in esophageal squamous cell cancer(r=-0.712,P＜0.001).Furthermore,patients with TNM stage Ⅲ,low differentiation,and lymph node metastasis exhibited a lower positive rate of OTUD3 and a higher positive rate of ILF2 compared to patients with TNM stage Ⅰ-Ⅱ,medium-high differentiation,and no lymph node metastasis(P＜0.05).The 3-year survival rate for the OTUD3-positive group was significantly higher than that of the OTUD3-negative group(Log-rank x2=5.869,P=0.015).The 3-year survival rate for the ILF2-positive group was significantly lower than that of the ILF2-negative group(Log-rank x2=16.257,P＜0.001).TNM staging,lymph node metastasis,degree of differentiation,OTUD3,and ILF2 were independent factors affecting the prognosis of esophageal squamous cell cancer patients.Conclusion Decreased expression of OTUD3 and increased expression of ILF2 in esopha-geal squamous cell cancer tissues are implicated in the malignant progression of esophageal squamous cell cancer and serve as independent factors affecting patient outcomes.
