ObjectiveTo explore the effects of Wumeiwan on liver metastasis and lung metastasis of colorectal cancer and its potential mechanism. MethodsFirstly， mice were randomized into control， low-dose （20 g·kg^-1） Wumeiwan， high-dose （40 g·kg^-1） Wumeiwan， and paclitaxel （10 mg·kg^-1） groups. Secondly， liver metastasis and lung metastasis models of colorectal cancer were established in mice. After 4 weeks of intervention， the body weight of each mouse was recorded， and the lung weight， liver weight， and survival time of mice with metastatic colorectal cancer were determined. Hematoxylin-eosin （HE） staining was employed to detect the effects of Wumeiwan on liver metastasis and lung metastasis. Real-time PCR was employed to determine the mRNA levels of M1 and M2 macrophage markers in the liver tissue. Finally， the content of M1 macrophage markers CD80 and CD86 in the liver tissue was measured by flow cytometry. ResultsCompared with the control group， Wumeiwan and paclitaxel reduced the body weight （P<0.01） and liver weight （P<0.01） and prolonged the survival of the mouse model of liver metastasis of colorectal cancer （P<0.01）. In the mouse model of lung metastasis of colorectal cancer， Wumeiwan and paclitaxel also reduced the body weight （P<0.01） and lung weight （P<0.01） and extended the survival time （P<0.01）. Histopathological results showed that compared with the control group， Wumeiwan inhibited the liver and lung metastases of colorectal cancer. Real-time PCR results showed that compared with the control group， Wumeiwan upregulated the mRNA levels of M1 macrophage markers IL-1β， IL-6， tumor necrosis factor-α （TNF-α）， inducible nitric oxide synthase （iNOS）， and prostaglandin-endoperoxide synthase 2 （PTGS2） in the liver and lung tissue of mice with liver metastasis and lung metastasis of colorectal cancer （P<0.01）. Meanwhile， Wumeiwan downregulated the mRNA levels of M2 macrophage markers Arg1， CD163， and CD206 （P<0.01）. Meanwhile， the flow cytometry results showed that compared with the control group， Wumeiwan increased the content of CD86 and CD80 （P<0.01）. In addition， immunohistochemical results showed that Wumeiwan promoted the expression of CD86 and inhibited the expression of CD206 in the liver and lung tissue of mice with liver metastasis and lung metastasis. ConclusionWumeiwan can inhibit the liver metastasis and lung metastasis of colorectal cancer by promoting the M1 polarization of macrophages in the liver and lung of the model mice.

Virus-related lymphoma exhibits a dual nature as both a hematologic malignancy and a viral infectious disease， making it more resistant to treatment and associated with poorer prognosis. This paper analyzes the understanding and therapeutic advantages of traditional Chinese medicine （TCM） in virus-related lymphoma. It proposes a TCM-based approach centered around syndrome differentiation， using standardized measurements of the overall TCM condition， multi-omics research of hematologic tumors， and artificial intelligence technologies to identify the "pre-condition" of virus-related lymphoma. A risk warning model will be established to early identify high-risk populations with viral infections that may develop into malignant lymphoma， thereby establishing a risk warning system for virus-related lymphoma. At the same time， a TCM health management approach will be applied to manage and regulate virus-related lymphoma， interrupting its progression and forming a human-centered， comprehensive， continuous health service model. Based on this， a standardized， integrated clinical prevention and treatment decision-making model for virus-related lymphoma， recognized by both Chinese and western medicine， will be established to provide TCM solutions for primary prevention of major malignant tumors.

Objective: To investigate the distribution of traditional Chinese medicine (TCM) syndromes and syndrome elements in lymphoma, as well as the correlation between TCM syndromes and Western clinical indicators, in order to analyze associations between TCM syndromes and these indicators. Methods: From January 2023 to May 2024, 216 patients with lymphoma who met the inclusion criteria in the Department of Hematology, Third People′s Hospital Affiliated to Fujian University of Traditional Chinese Medicine were enrolled. Four diagnostic methods were applied to perform TCM syndrome differentiation and extract syndrome elements. The correlations between various syndromes and blood test indicators of lactate dehydrogenase (LDH), β2-microglobulin (β2-MG), immunoglobulin G (IgG), immunoglobulin M (IgM), immunoglobulin A (IgA), white blood cell (WBC), hemoglobin (Hb), platelet count (PLT), neutrophil (NEUT), immunohistochemical markers of B-cell lymphoma-6 (BCL6), B-cell lymphoma-2 (BCL2), proto-oncogene MYC, and Ki67 protein expression, Ann Arbor staging, international prognostic index (IPI) score, bone marrow infiltration, concurrent infections during chemotherapy, and post-chemotherapy bone marrow suppression rate were analyzed. Results: Five TCM syndromes, ranked by frequency, were syndromes of yin deficiency with phlegm accumulation(41.67%), qi depression with phlegm obstruction(30.56%), cold-phlegm congelation and stagnation(12.96%), phlegm-blood stasis toxin(12.04%), and lingering pathogen due to deficient vital qi(2.77%). Yin deficiency(50.93%) and phlegm(45.37%) were the more prevalent syndrome elements. The TCM syndromes were correlated with β2-MG, PLT, MYC, BCL2/MYC, Ki67 protein expression, and bone marrow infiltration (P<0.05). No statistically significant differences were observed in Ann Arbor staging or IPI score across the syndromes. Compared to the syndrome of cold-phlegm congelation and stagnation, the syndrome of qi depression with phlegm obstruction exhibited higher levels of NEUT, MYC, BCL2/MYC, and Ki67 protein expression, as well as a higher rate of post-chemotherapy bone marrow suppression (P<0.05); the syndrome of phlegm-blood stasis toxin showed higher MYC and BCL2/MYC protein expression and a higher rate of post-chemotherapy bone marrow suppression rate (P<0.05); the syndrome of yin deficiency with phlegm accumulation demonstrated higher MYC and BCL2/MYC protein expression and bone marrow infiltration rates, whereas PLT level was lower (P<0.05); the syndrome of lingering pathogen due to deficient vital qi had higher MYC, BCL2/MYC, and Ki67 protein expression levels, as well as a higher rate of post-chemotherapy bone marrow suppression rate (P<0.05). Compared to the syndrome of qi depression with phlegm obstruction, the syndrome of phlegm-blood stasis toxin exhibited lower Ki67 protein expression (P<0.05); the syndrome of yin deficiency with phlegm accumulation had higher β2-MG level, bone marrow infiltration rate, and rate of concurrent infections during chemotherapy, whereas PLT and NEUT levels and the rate of post-chemotherapy bone marrow suppression rate were lower (P<0.05). Compared to the syndrome of phlegm-blood stasis toxin, the syndrome of yin deficiency with phlegm accumulation had higher β2-MG level, whereas NEUT and the rate of post-chemotherapy bone marrow suppression were lower(P<0.05); the syndrome of lingering pathogen due to deficient vital qi exhibited a higher Ki67 protein expression (P<0.05). Compared to the syndrome of yin deficiency with phlegm accumulation, the syndrome of lingering pathogen due to deficient vital qi also showed a higher Ki67 protein expression(P<0.05). Conclusion The syndrome of yin deficiency with phlegm accumulation is relatively common in lymphoma. There is a correlation between TCM syndromes and Western medicine clinical indicators. The presence of heat signs in the syndromes may indicate active disease and poor prognosis, while the presence of strong pathogenic factors and weak vital qi in the syndromes may indicate a severer chemotherapy-related bone marrow suppression.

ObjectiveThis study aims to observe the effect of sinomenine （SIN） on fatty acid binding protein 4 （FABP4） in synovial tissue of rats with osteoarthritis （OA） and investigate the therapeutic mechanism of SIN on OA， further providing new ideas for the management of osteoarthritis by traditional Chinese medicine （TCM）. MethodsAn OA rat model was constructed and randomly divided into a control group， an OA group， an OA + SIN-L group （50 mg·kg^-1）， an OA + SIN-M （100 mg·kg^-1）， an OA + SIN-H （200 mg·kg^-1）， and an OA + prednisone （PDN） group （5 mg·kg^-1）. Following surgical modeling for three weeks， an appropriate medication was administered for four weeks. During modeling and administration， a hot plate test was performed to detect the pain and swelling of the knee joints of the rats. The periarticular tissue was collected for arthropathological observation at the end of drug administration. The expression of cleaved Caspase-3， B-cell lymphoma-2 （Bcl-2）， Bcl-2 associated X protein （Bax）， and FABP4 in the synovial tissue of rats was detected by Western blot and real-time quantitative polymerase chain reaction （Real-time PCR）， and the expression and distribution of FABP4 protein in the synovial membrane were detected by immunofluorescence. ResultsCompared with those in the control group， the levels of inflammatory factors and FABP4 in the serum of rats in the OA group were significantly increased （P<0.05， P<0.01）， and joint swelling was significantly elevated （P<0.01）. The thermal pain threshold was significantly reduced （P<0.01）， and the expression of FABP4 protein and the fluorescence intensity were significantly increased （P<0.01）. The synovial tissue exhibited significantly increased inflammatory infiltration， proliferated fibroblasts， and an elevated apoptotic index （P<0.05， P<0.01）. Compared with those in the OA group， the serum lipid metabolism indexes of rats in the SIN administration group gradually returned to normal （P<0.05， P<0.01）， while the levels of inflammatory factors and FABP4 in the serum of rats in the SIN-administered group were significantly reduced （P<0.05， P<0.01）， and joint swelling was significantly decreased （P<0.05， P<0.01）. The thermal pain threshold was significantly elevated （P<0.05， P<0.01）， and the expression of FABP4 protein and fluorescence intensity in the synovial tissue were significantly decreased （P<0.05， P<0.01）. The synovial tissue displayed significantly reduced inflammatory infiltration and a decreased apoptotic index （P<0.05， P<0.01）. ConclusionThe therapeutic effect of SIN on OA may be related to the down-regulation of FABP4 expression， reduction of apoptosis， and inhibition of inflammatory factor expression.

Polygonatum sibiricum， as a traditional Chinese medicine with both medicinal and edible properties， has attracted considerable attention due to its functions of nourishing Yin and moistening the lungs， tonifying the spleen and benefiting Qi， and nourishing the kidneys and filling essence. Recent studies have demonstrated that Polygonatum sibiricum plays a significant role in regulating the immune system， effectively enhancing and improving the morphology and function of immune organs， stimulating the proliferation and activation of immune cells， and regulating the secretion and release of immune factors， thereby enhancing the immune function of the body and improving various immune-related diseases. Although a large number of studies have explored the pharmacological effects and mechanisms of P. sibiricum， there has been no systematic review and summary of its immune regulatory activity and mechanisms. Therefore， this article comprehensively reviews the research achievements of P. sibiricum polysaccharides and saponins in the field of immune regulation in recent years， and further sorts out the immune regulatory mechanisms of P. sibiricum in multiple aspects： including increasing the organ index of the spleen and thymus， increasing the number and activity of tumor-suppressive bone marrow hematopoietic stem cells， improving intestinal flora imbalance， regulating the quantity and proportion of T lymphocyte subsets， increasing the level of immunoglobulin， promoting the proliferation of macrophages， enhancing the activity of natural killer cells， increasing the number of white blood cells， and promoting the maturation of dendritic cells， providing a solid theoretical basis and scientific evidence for the research and application of P. sibiricum， and promoting its development and application in traditional Chinese medicine immune enhancers and various functional products.

Objective To explore the diagnosis and treatment experience of malignant peritoneal mesothelioma by analyzing the clinical characteristics of patients with single center peritoneal mesothelioma.Methods Retrospec-tively analyze the clinical data,including age and treatment regimens,of 99 patients with malignant peritoneal mes-othelioma admitted to Peking Union Medical College Hospital from June 2012 to July 2023.Kaplan-Meier for surviv-al analysis and Logistic and Cox regression were applied to assess the impact of factors like age and treatment regi-mens on survival time.Results The median age of diagnosis for 99 patients with peritoneal mesothelioma was 56 years,of which 82 were pathologically diagnosed.Among them,38 cases(51.4%)underwent tumor cell reduction surgery,and 57 cases(77.0%)underwent systemic or local treatment.The median survival time for all patients was 43 years.The age of diagnosis may affect the prognosis of patients with malignant mesothelioma,and those aged≥65 at the time of diagnosis have a worse prognosis.Conclusions Malignant peritoneal mesothelioma is a rare but invasive malignant tumor with a poor prognosis.There is still a need to develop novo drugs and comprehensive treat-ment strategies.

Objective: To investigate the association between high normal blood pressure, hypertension and microalbuminuria (MAU), so as to provide the basis for early screening and prevention of renal injury caused by hypertension. Methods: A multi-stage cluster random sampling method was used to select permanent residents aged 18 to 75 years from six provinces including Hebei, Hunan, Sichuan, Heilongjiang, Qinghai and Jiangxi from September to October 2021. Basic information and lifestyle behaviors were collected through questionnaires. Indices including height, weight and blood pressure were measured. Urinary microalbumin and creatinine were measured in 24-hour urine samples. The associations between high normal blood pressure, hypertension, and MAU were analyzed by using a multivariable logistic regression model. Results: A total of 1 982 residents were surveyed, with 996 residents aged <50 years (50.25%) and 986 residents aged ≥50 years (49.75%). There were 958 males (48.34%) and 1 024 females (51.66%). Normal blood pressure was observed in 653 residents (32.95%), high normal blood pressure in 748 (37.74%) and hypertension in 581 (29.31%). MAU was detected in 164 participants, with a detection rate of 8.27%. The detection rates of MAU among residents with normal blood pressure, high normal blood pressure, and hypertension were 2.14%, 8.16% and 15.32%, respectively, and the difference was statistically significant (P<0.05). Multivariable logistic regression analysis showed that after adjusting for gender, age, educational level, smoking, alcohol consumption, regular exercise and body mass index, the residents with high normal blood pressure (OR=3.535, 95%CI: 1.898-6.585) and hypertension (OR=7.232, 95%CI: 3.808-13.732) had higher risks of MAU compared to those with normal blood pressure; the residents with hypertension (OR=1.914, 95%CI: 1.340-2.735) had a higher risk of MAU compared to those with high normal blood pressure. Conclusions High normal blood pressure and hypertension are associated with an increased risk of MAU.

Objective:To evaluate the efficacy of esketamine combined with different doses of remimazolam for induction of general anesthesia in pediatric patients.Methods:One hundred and sixty pediatric patients of either sex, aged 3-6 yr, of American Society of Anesthesiologists Physical Status classification Ⅰ or Ⅱ, with body mass index of 13-20 kg/m 2, undergoing elective general anesthesia under a laryngeal mask, were divided into 4 groups ( n=40 each) by the random number table method: esketamine combined with propofol group (KP group) and esketamine combined with different doses of remimazolam group (0.2, 0.3, 0.4 mg/kg) groups (KR1 group, KR2 group, KR3 group). Esketamine 0.8 mg/kg was intravenously injected in the preanesthesia room. After entering the operating room, propofol 2.5 mg/kg was intravenously injected in KP group, and remimazolam 0.2, 0.3 and 0.4 mg/kg were intravenously injected in KR1, KR2 and KR3 groups, respectively. When the child lost consciousness and the Modified Observer′s Assessment of Alertness/Sedation Scale score<1, sufentanil and mevacurium were intravenously injected. When the Modified Observer′s Assessment of Alertness/Sedation Scale score≥1, rescue sedation was performed, and 3 min later the laryngeal mask airway was inserted. The onset time of sedation, response to laryngeal mask airway placement, rescue sedation, hypotension, tachycardia, bradycardia, bucking, hiccup, injection pain and apnea were recorded, and the increase rate of perfusion index (PI) was calculated. Results:No response to laryngeal mask implantation occurred in the four groups. Compared with KP group, the onset time of sedation was significantly prolonged, the incidence of hypotension, bradycardia, injection pain and apnea was decreased, the incidence of tachycardia was increased, and the increase rate of PI was decreased in KR1, KR2 and KR3 groups, and the rate of rescue sedation and incidence of bucking were increased in KR1 and KR2 groups ( P<0.05). Compared with KR1 group, the onset time of sedation was significantly shortened in KR2 group and KR3 group, and the rate of rescue sedation and incidence of bucking were decreased in KR3 group ( P<0.05). Compared with KR2 group, the onset time of sedation was significantly shortened, and the rate of rescue sedation was decreased in KR3 group ( P<0.05). There was no significant difference in the increase rate of PI, hypotension, bradycardia, tachycardia, injection pain and apnea among KR1, KR2 and KR3 groups ( P>0.05). There was no significant difference in the incidence of hiccup among the four groups ( P>0.05). Conclusions:Esketamine 0.8 mg/kg combined with remimazolam 0.4 mg/kg can be safely and effectively used for anesthesia induction and has milder inhibition of respiration and circulation as compared with esketamine combined with propofol in pediatric patients.

Objective To analyze the consistency between computer tomography angiography(CTA)and digital subtraction angiography(DSA)in evaluating the global limb anatomic staging system(GLASS)stage of patients with chronic limb-threatening ischemia(CLTI).Methods The clinical data of patients with CLTI,who were admitted to the First Affiliated Hospital of Xi'an Jiaotong University of China to receive treatment between January 2017 and December 2020,were retrospectively analyzed.Taking the DSA assessment as the gold standard,the consistency of CTA and DSA in evaluating the GLASS stage of patients with CLTI was analyzed.Results In the assessment of GLASS stage of CLTI,CTA showed strong agreement with DSA.The weighted Kappa coefficient of CTA and DSA for the staging of femoropopliteal segment was 0.798(95％CI=0.722-0.873,P＜0.01),and the weighted Kappa coefficient of CTA and DSA for the staging of infrapopliteal artery segment was 0.785(95％ CI=0.725-0.845,P＜0.0l).For the overall staging of GLASS,the weighted Kappa coefficient of CTA and DSA was 0.832(95％ CI=0.752-0.91 1,P＜0.01).All the above results indicated that a very strong consistency existed between CTA and DSA in evaluating the GLASS stage of patients with CLTI.Conclusion CTA examination of lower limb can accurately evaluate GLASS score and stage of CLTI patient's target lesions,which is helpful in diagnosing lower extremity arteriosclerosis occlusion disease as well as in assessing the technical difficulty degree of its revascularization operation.(J Intervent Radiol,2024,33:300-303)

Existing antidepressant treatments are generally suboptimal for patients with bipolar disorder(BD).Several studies have explored the efficacy of light therapy(LT)in patients with bipolar depression,along with investigating parameters,devices,and safety aspects of LT.This paper provides a review of these aspects.Numerous meta-analyses and randomized controlled trials have indicated that LT could significantly improve depressive symptoms in BD patients,with both low and high intensity white light having this effect,while the antidepressant effect of blue light remains unclear.LT takes effect rapidly,preferably in the morning,with each session lasting between 30 to 60 minutes,but there is no consensus on the most beneficial LT course for BD patients.The most commonly used device for LT is a lightbox.However further exploration is need regarding the safety of LT glasses.When LT devices that meet safety standards is selected,the overall safety of LT will be high and risk of manic or hypomanic switch will be low for BD patients.In conclusion,LT holds promise for patients with bipolar depression,and further research on LT for BD patients should be conducted to explore LT strategies and develop LT prescriptions.
