In response to the clinical needs of cancer treatment and rehabilitation, Professor Lin Hongsheng proposed the Wuzhi Wuyang (five treatments and rehabilitation) concept on the basis of years of clinical experience and the Guben Qingyuan (consolidate the foundation and clear the source) theory. Wuzhi Wuyang emphasizes the importance of treatment and rehabilitation and aims to provide personalized and stage-specific treatment and rehabilitation plans by integrating the advantages of traditional Chinese medicine (TCM) and modern medicine to achieve comprehensive life-cycle management for patients with cancer. The proposal of Wuzhi Wuyang has provided new ideas and methods for the treatment, prevention, and rehabilitation of cancer, along with valuable references for clinical practice and academic research. This article summarizes the connotation of Wuzhi Wuyang and its application in the comprehensive management of cancer prevention and treatment with TCM.

Ischemia-reperfusion (I/R) injury following skin flap transplantation is a critical factor leading to flap necrosis and transplant failure. Antagonizing inflammatory responses and oxidative stress are regarded as crucial targets for mitigating reperfusion injury and enhancing flap survival. In this study, caffeic acid-vanadium metal polyphenol nanoparticles (CA-V NPs) were prepared for the treatment of skin flap ischemia and reperfusion. This study was conducted using a one-step method to prepare new types of CA-V NPs with uniform sizes and stable structures. In vitro, the CA-V NPs exhibited CAT-like and SOD-like activities and could effectively scavenge ROS, generate oxygen, and alleviate oxidative stress. In the H₂O₂-induced cellular oxidative stress model, CA-V NPs effectively reduced ROS levels and inhibited apoptosis through the XIAP/Caspase-3 pathway. In the cellular inflammation model induced by LPS combined with IFN-γ, CA-V NPs reprogrammed macrophage polarization toward the M2 phenotype and reduced inflammatory responses by reducing the expression of the chemokines CCL4 and CXCL2. In addition, animal experiments have shown that CA-V NPs can alleviate oxidative stress in skin flap tissues, inhibit apoptosis, promote angiogenesis, and ultimately improve the survival rate of skin flaps. CA-V NPs provide a new target and strategy for the treatment of flap I/R injury.

Ferroptosis is a form of programmed cell death characterized by overwhelmed lipid oxidation, and it has emerged as a promising strategy for cancer therapy. Enhanced ferroptosis could overcome the limitations of conventional therapeutic modalities, particularly in difficult-to-treat tumors. In this study, we developed a dual-modality therapy in nanomedicine by combining paclitaxel (PTX) chemotherapy and pyropheophorbide-a (Ppa) phototherapy. Heparin (HP) was grafted with poly(N-(2'-hydroxy) propyl methacrylamide) (pHPMA) using reversible addition-fragmentation chain transfer polymerization to form HP-pHPMA (HH), which was utilized to deliver Ppa and PTX, yielding HP-pHPMA-Ppa (HH-Ppa) and HP-pHPMA-PTX (HH-PTX), respectively. The prodrug-based combinational nanomedicine (HH-PP) was formed by co-assembly of HH-PTX and HH-Ppa. It was found that HH-PP treatment significantly disrupted lipid metabolism in triple-negative breast cancer (TNBC) cells, induced extensive lipid oxidation, and promoted ferroptosis. In vivo, HH-PP intervention achieved a tumor growth inhibition rate of 86.63% and activated adaptive immunity with an elevated CD8⁺ cytotoxic T cell infiltration level. This combinational nanomedicine offers a promising platform for co-delivery of multiple therapeutic agents. It exerts a promising anti-tumor effect via enhanced ferroptosis and ferroptosis-induced immune activation by disrupting lipid metabolism in TNBC cancer cells.

Results: There was a good linear relationship for the 9 kinds of biogenic amines at 2.0 to 500.0 μg/L (r≥0.996). The limit of detection was 0.1 to 0.2 mg/L, and the limit of quantitation was 0.3 to 0.6 mg/L. The spike recovery rate of 9 kinds of biogenic amines ranged from 83.5% to 108.6% at 0.1 and 1.0 mg/L, with relative standard deviations of 2.8% to 8.7%. Conclusion Non-derivation-prime ultra-high performance liquid chromatography-tandem mass spectrometry can be used for the rapid quantitative detection of biogenic amines in yellow rice wine.

BACKGROUND:Gingival thickness is an important indicator to determine gingival phenotype.The correct evaluation of gingival phenotype is helpful for the smooth going of periodontal surgery,implant implantation and orthodontic treatment.The search for a comfortable,accurate and convenient method of measuring gingival thickness has always been a research hotspot in this field. OBJECTIVE:To analyze the gingival thickness in different dental positions and to study the consistency of cone-beam computed tomography(CBCT)image and digital intraoral scanners and cone-beam computed tomography(DIS-CBCT)superimposition image for measuring gingival thickness and determining whether the gingiva is thick or thin. METHODS:Twenty volunteers(10 males and 10 females)with complete maxillary dentition were recruited.The thickness of the gingiva 2 mm below the buccal gingival margin of 160 teeth was measured by CBCT image and DIS-CBCT digital superimposition image.Gingival thickness was used to determine whether the gingiva was thick or thin.Paired t-test was used to analyze the differences in gingival thickness measured by the two methods.Pearson correlation analysis was used to evaluate the correlation between the gingival thickness results of the two methods.The intraclass correlation coefficient(ICC)and Bland-AItman chart were used to analyze the repeatability and consistency in measuring gingival thickness using the two methods.Kappa value was used to analyze the consistency in determining whether the gingiva was thick or thin using the two methods. RESULTS AND CONCLUSION:The gingival thickness measured by CBCT image and DIS-CBCT digital superimposition image was(1.47±0.39)and(1.42±0.36)mm,respectively(t=5.673,P＜0.05).Pearson correlation analysis showed that the gingival thickness measured by the two methods was positively correlated(r=0.968,P＜0.001).In the CBCT group,the values of intraobserver and interobserver ICC were 0.980-0.982 and 0.984,respectively;in the DIS-CBCT group,the values of intraobserver and interobserver ICC were 0.941-0.984 and 0.964,respectively(P＜0.001).The intergroup ICC value of gingival thickness measured by the two methods was 0.967(P＜0.001).Bland-AItman analysis showed that 4.37%(7/160)of the points measured by both methods for gingival thickness was outside the 95%limits of agreement.There were 71 cases of thick-gingiva and 89 cases of thin-gingiva measured by CBCT imaging,and 59 cases of thick-gingiva and 101 cases of thin-gingiva measured by DIS-CBCT digital superimposition image.The Kappa value of the two groups was 0.845(P＜0.001).These findings indicate that there is a significant difference in the thickness measurement of the gingiva 2 mm below the gingival margin between the CBCT group and the DIS-CBCT group,but the correlation is very strong.The repeatability and consistency of gingival thickness measurement are both high,and there is a good consistency between the two methods when used to determine whether the gingiva is thick or thin.

Objective To observe the value of nomogram model based on clinical and ultrasonic characteristics for diagnosing lymphoma.Methods Data of 176 patients with suspected lymphoma due to enlarged superficial lymph nodes were retrospective analyzed.The patients were divided into lymphoma group(n=90,invasive subgroup[n=40]and non-invasive subgroup[n=50])or non-lymphoma group(n=86)based on pathological results.Clinical and ultrasonic data were compared between groups and subgroups.Multivariate logistic regression was used to screen the independent risk factors of lymphoma,and then a nomogram was constructed.Receiver operating characteristic curves were drawn to evaluate the efficacy of conventional ultrasound,conventional contrast-enhanced ultrasound(C-CEUS),high-frame-rate contrast-enhanced ultrasound(H-CEUS)and nomogram for diagnosing lymphoma.Results Multivariate logistic regression analysis revealed that age＞59 years,cortical stripe/reticular hyperecho of lymph nodes and"centrifugal firework"enhancement pattern showed with H-CEUS were all independent risk factors of lymphoma(all P＜0.05).Taken 59 years as the best cut-off value of patients'age,the sensitivity,specificity,accuracy and the area under the curve(AUC)for diagnosing lymphoma was 67.78%,58.10%,63.06%and 0.630,respectively.The sensitivity,specificity,accuracy and AUC of cortical stripe/reticular hyperecho of lymph nodes for diagnosing lymphoma was 73.33%,58.10%,65.91%and 0.657,respectively,while of"centrifugal firework"pattern enhancement in H-CEUS was 77.78%,69.80%,73.86%and 0.738,respectively.AUC of conventional ultrasound,C-CEUS,H-CEUS and nomogram for diagnosing lymphoma was 0.657,0.540,0.738 and 0.844,respectively.Conclusion Nomogram model based on clinical and ultrasonic characteristics had good diagnostic efficacy for lymphoma,and"centrifugal firework"pattern enhancement in H-CEUS could be regarded as the specific characteristic of lymphoma.

Objective To evaluate the short-term clinical efficacy of photodynamic therapy(PDT)assisted mechanical debridement(MD)in the treatment of peri-implantitis.Methods According to the new international classification of periodontal diseases and peri-implant diseases in 2018,single tooth implants diagnosed as peri-implantitis were included.Before treatment,the probing depth(PD),modified sulcus bleeding index(mSBI),and modified plaque index(mPLI)were recorded as the baseline,with mSBI≥1 sites as the treatment sites.The MD group was a control group,and only mechanical subgingival debridement was performed.The PDT group was treated with photodynamic therapy twice,immediately after subgingival debridement and one week after.Follow-up was ar-ranged at 6 and 12 weeks after the end of treatment to examine the changes in PD,mSBI,and mPLI at the included implant treatment sites.Results A total of 35 patients were included in this study,with 38 teeth affected by peri-implantitis and 154 treatment sites.The PDT group and MD group included 20 and 18 implants respectively,with a total of 78 treatment sites included in the PDT group,51 sites with PD≥6 mm,and 27 sites with PD＜6 mm.A total of 76 treatment sites were included in the MD group,including 53 sites with PD≥6 mm and 23 sites with PD＜6 mm.At baseline,there was no statistically significant difference in PD,mSBI,and mPLI between the two groups.At 6 and 12 weeks after treatment,there were statistically significant differences in clinical indicators between the two groups compared to baseline(P＜0.05).Among them,the mSBI in the PDT group was significantly lower than that in the MD group at 6 weeks after treatment(P＜0.05).At sites with PD≥6 mm,the mSBI of the PDT group was significantly lower than that of the MD group at 6 and 12 weeks after treatment(P＜0.05).The number of implants in the PDT group and MD group that reached the treatment endpoint at 12 weeks follow-up was 70.00%and 55.56%,respectively,and there was no difference between the two groups(P＞0.05).Conclusion Photodynamic therapy assisted with mechanical debridement can effectively treat peri-implantitis and is a safe and ef-fective auxiliary method,and has significant therapeutic effects on in-flammation control and improvement of mSBI in those sites with PD≥6 mm.

Objective To explore the effect and possible mechanism of aerobic exercise and empagliflozin(EMPA)on isoproterenol(ISO)-induced pathological cardiac remodeling.Methods Mice were divided randomly into control(Con),ISO,exercise(EX)+ISO,EMPA+ISO,and EX+EMPA+ISO groups.Mice in the EX groups were trained continuously for 6 weeks,mice in the EMPA groups were gavaged continuously for 4 weeks,and mice in the ISO groups were injected subcutaneously with ISO for 7 days before dissection.After euthanasia,the whole heart mass index,left heart mass index,heart mass to tibial length ratio,and left heart mass to tibial length ratio were calculated by weighing and measuring.Pathological changes,collagen fiber deposition,and myocardial cell cross-sectional area in the hearts were detected by hematoxylin and eosin,Sirius red,and wheat germ agglutinin staining.The expression levels of genes and proteins related to cardiac fibrosis and hypertrophy,macrophage infiltration,ferroptosis,and the phosphoinositide 3-kinase(PI3K)/AKT pathway were examined by quantitative reverse transcription-polymerase chain reaction,Western Blot,and immunofluorescence staining.Results(1)The whole heart mass index,left heart mass index,heart mass to tibial length ratio,and left heart mass to tibial length ratio showed downward trends in the EX+ISO group compared with the ISO group.The whole heart mass index and left heart mass index were significantly decreased in the EMPA+ISO group(P＜0.01,P＜0.05),and the heart mass to tibial length ratio and left heart mass to tibial length ratio were both down regulated.Mice in the EX+EMPA+ISO group had a significant decrease in whole heart mass index(P＜0.05),and the other three indicators were all down-regulated.(2)Myocardial cells were more orderly in the three intervention groups compared with the ISO group,with significant reductions in inflammatory cell infiltration(P＜0.01),the area of cardiac fibrosis,and the cross-sectional area of myocardial cells(P＜0.001).(3)The mRNA and protein expression levels of Col 1 and Anp were significantly reduced in the three intervention groups compared with the ISO group(P＜0.05,P＜0.01,P＜0.001).Col 3 mRNA expression significantly reduced in the EMPA+ISO and EX+EMPA+ISO groups(P＜0.05),and showed a downward trend in the EX+ISO group.(4)Macrophage infiltration and IL-6 mRNA levels were significantly reduced in the three intervention groups compared with the ISO group(P＜0.05,P＜0.01,P＜0.001).(5)Nrf2 and Gpx4 mRNA levels were upregulated in the three intervention groups compared with the ISO group,with a significant increase in GPX4 protein expression(P＜0.01,P＜0.001)and a significant decrease in HO-1 protein expression(P＜0.01,P＜0.001).(6)Pi3k mRNA levels were significantly increased in the EX+ISO group compared with the ISO group(P＜0.05),and Pi3k mRNA was upregulated in the EMPA+ISO and EX+EMPA+ISO groups.Akt mRNA levels showed an upward trend in the three intervention groups.PI3K and phospho-AKT protein levels were significantly increased in the EX+ISO group(P＜0.01,P＜0.05),and showed an increasing trend in the EMPA+ISO and EX+EMPA+ISO groups.Conclusions Moderate intensity aerobic exercise,the novel hypoglycemic drug EMPA,and their combination can alleviate ISO-induced pathological cardiac remodeling,possibly via a mechanism related to activation of the PI3K/AKT signaling pathway and inhibition of cardiac ferroptosis.

Objective: Attention deficit hyperactivity disorder (ADHD) is a polygenic neurodevelopmental disorder with significant gender differences. The sexual dimorphism of ADHD may be associated with estrogen acting through estrogen receptors (ESR). This study investigates the impact of ESR gene polymorphism and its interactions with neurodevelopmental genes on ADHD susceptibility. Methods: The study compared genotyping data of single nucleotide polymorphisms in ESR1 and ESR2 in 1,035 ADHD cases and 962 controls. The gene-gene interactions between ESR genes and three neurodevelopmental genes (brain-derived neurotrophic factor [BDNF], synaptosomal-associated protein of 25 kDa gene [SNAP25], and cadherin-13 [CDH13]) in ADHD were investigated using generalized multifactor dimensionality reduction and verified by logistic regression analysis. Results: The G allele of rs960070/ESR2 (empirical p=0.0076) and the A allele of rs8017441/ESR2 (empirical p=0.0426) were found significantly higher in ADHD cases than in the controls but not in male or female subgroups. Though no difference was found in all subjects or females, the A allele of rs9340817/ESR1 (empirical p=0.0344) was found significantly higher in ADHD cases than controls in males. We also found genetic interaction models between ESR2 gene, neurodevelopmental genes and ADHD susceptibility in males (ESR2 rs960070/BDNF rs6265/BDNF rs2049046/SNAP25 rs362987/CDH13 rs6565113) and females (ESR2 rs960070/BDNF rs6265/BDNF rs2049046) separately, though it was negative in overall subjects. Conclusion The ESR gene polymorphism associates with ADHD among Chinese Han children, with interactions between ESR genes and neurodevelopmental genes potentially influencing the susceptibility of ADHD.

  Objective  Different from other etiologies of early-onset scoliosis (EOS), congenital early-onset scoliosis (CEOS) is mainly linked to vertebral anomalies, such as formation failures and segmentation failures at the apex segments. So far, there is little research on CEOS patients who have completed traditional growing rods (TGR) treatment, and the initial outcomes of TGR with or without apical control technique (ACT) are different. Therefore, we compared the "final" results of CEOS patients who completed TGR treatment with or without ACT.  Methods  We conducted a retrospective study of CEOS patients who completed TGR treatment from 2007—2020. They either had final fusion or were followed up after reaching skeletal maturity. We split the patients into two groups based on whether they had ACT with TGR or not. The ACT-TGR group had apical vertebrectomy/hemivertebrectomy with short fusion and TGR. The TGR-only group had only TGR. We looked at their demographic features, radiographic measurements, and complications.  Results  This study enrolled 46 CEOS patients, of which 13 patients were in the ACT-TGR group and 33 patients in the TGR group. The ACT-TGR group had a longer distraction interval (1.17 years vs. 0.75 years). The ACT-TGR group had a larger preoperative main curve [87.00(63.50, 98.00)], but the residual curve degrees were comparable between the two groups at the last follow-up (P=0.354). At the last follow-up, the T1-12 and T1-S1 heights were similar between the two groups. The ACT-TGR group had a lower number of implant-related complications per patient (0.77 vs. 1.48). Three patients in the ACT-TGR group underwent final fusion, while 17 patients in the TGR group underwent final fusion (P=0.060).  Conclusions  Both ACT-TGR and traditional TGR coud effectively correct deformity and preserve spinal growth in CEOS patients. ACT-TGR had a better corrective effect on patients with severe deformity and did not have a significant impact on spinal height. For patients with acceptable correction, spontaneous fusion and without implant failure, retaining the implant and continuing observation could be a strategy for graduating from growing rod treatment.
