Objective To investigate the impact of dietary protein intake on the prevalence of type 2 diabetes in adult residents, and to provide a reference for formulating diabetes prevention and control measures. Methods The research was based on cross-sectional survey data from the Nutrition and Health Follow-up Study of Chinese Residents in Chongqing (2021). Energy and nutrient intake was calculated in combination with the Chinese food composition table. Multivariate logistic regression was used to analyze the association between dietary protein and diabetes, and then restricted cubic spline regression (RCS) was used to analyze the dose-response relationship between dietary protein intake and the development of diabetes. Results Among the 1 415 adult residents, dietary intake of total protein, animal protein, and plant protein was 69.69g/d, 26.26g/d, and 43.43g/d, respectively. The ratio of protein to energy supply was 14.31%, and the prevalence of diabetes was 18.02%. Comparing with the residents in the first percentile of total dietary protein intake, the multivariable-adjusted odds ratios of those in the second and third percentile were 1.754 and 2.453 respectively. Comparing the residents in the third percentile with those in the first percentile, the multivariable-adjusted odds ratios of diabetes were 1.592 for protein energy supply ratio, and 1.558 for animal protein intake. Conclusion High protein intake, high protein energy supply ratio and high animal protein intake may increase the risk of diabetes, and different types of protein may have different effects on diabetes.

Colorectal cancer （CRC） ranks as the second leading cause of cancer death worldwide. Although preventive colonoscopy screening has improved the survival rate of CRC patients in the past few years， there are still many patients diagnosed after symptoms appear. The surgery for CRC carries high risks and high recurrence， and ideal therapies remain to be developed. The Janus kinase/signal transducer and activator of transcription （JAK/STAT） signaling pathway has become a focus of research due to its central role in cellular activities. As a classic oncogenic pathway， the JAK/STAT signaling pathway offers new possibilities for diagnosing and treating various malignancies， and it paves a new way for developing therapies for CRC. This pathway not only participates in basic cellular processes， such as proliferation， differentiation， and apoptosis but also plays a crucial role in immune responses and inflammation. Abnormal activation of the JAK/STAT signaling pathway is closely related to the occurrence and development of CRC. Studies have shown that the active components and compound prescriptions of traditional Chinese medicine （TCM） can inhibit the proliferation， invasion， migration， and angiogenesis while promoting the apoptosis and autophagy of CRC cells by interfering with the JAK/STAT signaling pathway. Furthermore， this pathway may also play a role in regulating the sensitivity of tumor cells to chemotherapy and radiotherapy， thus influencing the effectiveness of tumor treatment and impeding the progression of CRC. In recent years， research results have been updated rapidly， and previous literature summaries have failed to incorporate the latest findings， creating obstacles to accessing current literature. Therefore， this article supplements and summarizes information from the definition of the JAK/STAT pathway， association of this pathway with CRC， and TCM intervention of CRC. This review aims to provide references for future development of molecular biology regarding CRC and the research and development of new drugs.

This article retrospectively analyzed the clinical data of three recipients who developed acute antibody mediated rejection (AMR) after receiving different courses of immunotherapy prior to liver transplantation for hepatocellular carcinoma. It focused on their diagnostic and therapeutic processes, including the immunosuppressive induction regimen [rabbit anti-human thymocyte globulin (rATG) + methylprednisolone] , postoperative liver function changes, diagnostic methods for acute AMR (such as allograft liver biopsy, panel reactive antibody testing, and donor-specific antibody testing) , and the combination treatment strategies used (rATG, rituximab, intravenous immunoglobulin, and plasma exchange). The aim of this article is to summarize the clinical characteristics, diagnosis, and treatment experiences of acute AMR occurring after liver transplantation in patients with liver cancer who had received immunotherapy, explore the potential risks involved, and provide a reference for clinicians in managing such cases.

Aim To investigate the effects of the fangchinoline derivative LYY-32 on the biological prop-erties of the BLM642-1290 DNA helicase,in order to lay a foundation for further research on its antitumor activity.Methods Fluorescence polarization assay,malachite green-phosphate and ammonium molybdate colorime-try,and fluorescein-labeled DNA gel electrophoresis experiments were conducted to study the effects of fangchinoline derivative LYY-32 on the DNA binding activity,ATPase activity,and DNA unwinding activity of BLM642-1290 DNA helicase.The effects of LYY-32 on the DNA unwinding activity of DNA helicase in cells were studied using fluorescent techniques and time-lapse microscopy.Ultraviolet spectral scanning was used to investigate the effects of LYY-32 on the confor-mation of the BLM642-1290 DNA helicase.Results At a concentration of 10 μmol·L-1,the inhibition rate of LYY-32 on BLM642-1290 DNA helicase binding to dsDNA was 53.17％.At a concentration of 5 μmol·L-1,the inhibition rate of LYY-32 on BLM642-1290 DNA helicase binding to ssDNA was 88.49％.The inhibition rate of LYY-32 on the ATPase activity of BLM642-1290 DNA he-licase was 89.3％at a concentration of 50 μmol·L-1.When the concentration of LYY-32 exceeded 5μmol·L-1,its inhibition rate on the DNA unwinding activity of BLM642-1290 DNA helicase was 100％.LYY-32 also significantly inhibited the DNA unwinding ac-tivity of DNA helicase in cells.However,LYY-32 had no effect on the conformation of BLM642-1290 DNA heli-case.Conclusion The DNA binding activity,AT-Pase activity,and DNA unwinding activity of BLM642-1290 DNA helicase could be significantly inhibi-ted by the fangchinoline derivative LYY-32.

To address the issue of reduced signal quality of photoplethysmography caused by local fluctuation,an approach called locally orthogonal weighted polynomial fitting(LOWPF)is proposed for signal smoothing.After determining the positions of the fluctuation sequences using the forward-backward difference XOR method,weighted polynomial fitting is applied to these sequences,and the fitted values are used to replace the fluctuation sequences to achieve signal smoothing.By constructing orthogonal basis functions,the condition number of the coefficient matrix is reduced,and the stability of the equation system solution for higher-order fitting is improved.Simulation results demonstrate that the smoothed signal's XOR smoothness of the proposed method surpasses that of the moving average algorithm and the empirical mode decomposition reconstruction algorithm.The smoothing results on 241 sets of measured PPG signals show that LOWPF achieves an efficiency of smoothness of 89.10%,significantly higher than the 78.05%of empirical mode decomposition and the 59.13%of the 5-point moving average algorithm.LOWPF has promising application prospects for smoothing signals with significant local fluctuations.

Objective:To investigate whether the highly expressed chemokine ligand 17(CCL17)in cervical cancer(CC)pro-motes the progression of CC through M2 macrophage polarization.Methods:The effect of CCL17 on the expression of IL-27 in CC cell line was detected by flow cytometry and ELISA.The effects of CCL17 and IL-27 on proliferation and differentiation of U937 cells were analyzed.The co-culture model of macrophages and CC cells were established to detect the effects of CCL17 on the proliferation of U937 and CC cells.Results:The CC cells secreted significantly higher levels of IL-27 after stimulation with CCL17.In addition,IL-27 but not CCL17 significantly upregulated interleukin 27 receptor(IL-27R,consisted of WSX-1 and GP130)on U937 cells.IL-27 de-rived from CC cells can promote the proliferation of U937 cells and induce the polarization of M2 macrophages.In the co-culture sys-tem,the level of IL-27 secreted by CC cells stimulated by CCL17 was significantly increased,and both CCL17 and IL-27 promoted the proliferation of CC and U937 cells,and the effect of CCL17 was partially reversed by αIL-27.Conclusion:CCL17 promotes the proliferation of macrophages and induces M2 polarization by stimulating CC cells to secrete IL-27,thereby enhancing the crosstalk be-tween CC cells and macrophages.Eventually,CCL17 participates in the malignant evolution of CC.

OBJECTIVE: To compare clinical efficacy between side-opening and front-opening bone cement injectors in percutaneous kyphoplasty(PKP) for the management of thoracolumbar osteoporotic vertebral compression fractures(OVCFs). METHODS: A retrospective cohort study was conducted, comprising 62 patients with single-segment thoracolumbar OVCFs (T₁₁-L₂), who underwent bilateral PKP at our department during the period from June 2020 to October 2021. Patients were categorized into two groups based on the specific bone cement injector employed during the surgical procedure: the side-opening group (n=29) and the front-opening group (n=33). Among them, the side-opening group consisted of 6 male and 23 female patients, with a mean age of (73.32±9.11) years. The front-opening group included 7 male and 26 female patients, with a mean age of (71.29±10.39) years. The variables encompassed essential patient characteristics were recorded, such as gender, age, bone mineral density (BMD), and fracture level (T₁₁-L₂), as well as procedural aspects, including operation duration, cement injection volume, cement distribution type (lobular or diffuse), occurrence of cement leakage, pre-and post-operative visual analogue scale (VAS) pain scores, and vertebral compression ratio. RESULTS: All patients underwent successful surgery, with a mean follow-up duration of (15.37±3.03) months. There were no statistically significant differences in gender, age, BMD, fracture level, preoperative vertebral compression degree, and VAS scores between the side-opening group and the front-opening group (P>0.05). The operation time, the mean cement injection volumes, the distribution of bone cement within the vertebrae has no statistically significant difference between two groups(P>0.05). Both the side-opening and front-opening groups showed significant improvements in VAS scores at 3 days and 6 months after operation (P<0.05). However, there was no significant difference in VAS scores between the two groups at both 3 days and 6 months after the operation (P>0.05). CONCLUSION Side-opening bone cement injectors in bilateral PKP surgery for single-segment thoracolumbar OVCF achieve similar clinical efficacy as front-opening injectors, without significant improvement in cement distribution and containment.

OBJECTIVE: To observe the clinical efficacy of 3D printing spinal external fixator combined with McKenzie therapy for patients with lumbar dics herniation (LDH). METHODS: Sixty patients with LDH between January 2022 and January 2023 were enrolled. Among them, 30 patients were given McKinsey training. According to different treatment methods, all patients were divided into McKenzie group and McKenzie + 3D printing group, 30 patients in each group. The McKenzie group provided McKenzie therapy. The McKenzie + 3D printing group were treated with 3D printing spinal external fixation brace on the basis of McKenzie therapy. Patients in both groups were between 25 and 60 years of age and had their first illness. In the McKenzie group, there were 19 males and 11 females, with an average age of (48.57±5.86) years old, and the disease duration was (7.03 ±2.39) months. The McKenzie + 3D printing group, there were 21 males and 9 females, with an average age of (48.80±5.92) years old, and the disease duration was(7.30±2.56) months. Pain was evaluated using the visual analogue scale (VAS), and lumbar spine function was assessed using the Oswestry disability index (ODI) and the Japanese Orthopaedic Association (JOA) score. VAS, ODI and JOA scores were compared between two groups before treatment and at 1, 3, 6, 9 and 12 months after treatment. RESULTS: All patients were followed up for 12 months. The VAS for the McKenzie combined with 3D printing group before treatment and at 1, 3, 6, 9, and 12 months post-treatment were(6.533±0.860), (5.133±1.008), (3.933±0.868), (2.900±0.759), (2.067±0.640), (1.433±0.504), respectively. In the McKenzie group, the corresponding scores were (6.467±0.860), (5.067±1.048), (4.600±0.968), (3.533±1.008), (2.567±0.728), (1.967±0.809), respectively. The ODI of the McKenzie group before treatment and at 1, 3, 6, 9, and 12 months post-treatment were (41.033±6.810)%, (37.933±6.209)%, (35.467±6.962)%, (27.567±10.081)%, (20.800±7.531)%, (13.533±5.158)%, respectively. For the McKenzie combined with 3D printing group, the corresponding ODI were(38.033±5.605)%, (33.000±6.192)%, (28.767±7.045)%, (22.200±5.517)%, (17.700±4.836)%, (11.900±2.771)%, respectively. The JOA scores of the McKenzie combined with 3D printing group before treatment and at 1, 3, 6, 9, and 12 months post-treatment were(8.900±2.074), (13.133±2.330), (15.700±3.583), (20.400±3.480), (22.267±3.084), (24.833±2.640), respectively. In the McKenzie group, the corresponding scores were(9.200±2.091), (12.267±2.406), (15.333±3.198), (18.467±2.240), (20.133±2.751), (22.467±2.849), respectively. Before the initiation of treatment, no statistically significant differences were observed in the VAS, ODI, and JOA scores between two groups (P>0.05). At 3, 6, 9, and 12 months post-treatment, the VAS in the McKenzie combined with 3D printing group was significantly lower than that in the McKenzie group, and the difference was statistically significant (P<0.05). The comparison of ODI between two groups at 1, 3, 6, 9, and 12 months post-treatment revealed statistically significant differences (P<0.05). At 6, 9, and 12 months post-treatment, the JOA score in the McKenzie combined with 3D printing group was significantly higher than that in the McKenzie-only group, and the difference was statistically significant (P<0.05). CONCLUSION The combination of 3D printed functional spinal external fixation brace with McKenzie therapy can significantly improve and maintain lumbar function in patients with LDH.

Objective:To explore the influencing factors for pathological upgrading in prostate cancer patients with a Gleason score of 3 + 3 undergoing targeted biopsy，and to establish a nomogram prediction model.Methods:A retrospective analysis was conducted on 191 patients with localized prostate cancer diagnosed with a Gleason score of 3 + 3 through targeted biopsies at the First Affiliated Hospital of Nanjing Medical University from January 2020 to June 2024. The age of the patients was 67（61，73）years，with prostate-specific antigen（PSA）level of 7.44（5.53，10.19）ng/ml，prostate volume of 35.64（26.59，48.97）ml，and PSA density（PSAD）of 0.20（0.14，0.31）ng/ml 2. Among them，61 cases（31.94%）had a Prostate Imaging Reporting and Data System（PI-RADS）score of 3，104 cases（54.45%）had a score of 4，and 26 cases（13.61%）had a score of 5. The diameter of the main lesion was 10.75（7.86，14.00）mm. The lesions were located in the peripheral zone in 78 cases（40.84%），the transition zone in 99 cases（51.83%），and the anterior fibromuscular stroma in 14 cases（7.33%）. The lesions were found at the apex in 56 cases（29.32%），in the body in 120 cases（62.83%），and at the base in 15 cases（7.85%）. MRI revealed only one lesion with a PI-RADS score ≥ 3 in 131 cases，two suspected lesions in 43 cases，three suspected lesions in 12 cases，and four suspected lesions in 5 cases. Systematic biopsy was positive in 121 cases（63.4%）and negative in 70 cases（36.6%）. The lesions were confined to the left lobe in 63 cases（32.98%），right lobe in 68 cases（35.60%），and involved both lobes in 60 cases（31.41%）. The interval between biopsy and surgery was 9.0（7.0，14.0）days. Univariate analyses were performed using Mann-Whitney U tests or χ2 tests，and multivariate logistic regression was used to identify independent predictors of pathological upgrading. A nomogram model was constructed based on these independent predictors. The model’s discriminative ability was assessed using the area under the receiver operating characteristic（ROC）curve（AUC），and internal validation of the model’s consistency was conducted using the bootstrap resampling method. Decision curve analysis（DCA）was performed to assess clinical utility. Results:Among the 191 cases，60（31.4%）had no pathological upgrading after surgery，while 131（68.6%）showed upgrading. Univariate analysis showed that the maximum diameter of the main lesion［9.0（6.0，13.2）mm vs. 11.0（8.4，14.0）mm］，number of suspicious lesions on MRI［1.0（1.0，1.0）vs. 1.0（1.0，2.0）］，number of positive systematic biopsy cores［1.0（0，2.0）vs. 1.0（0，3.0）］，percentage of positive systematic biopsy cores［0.08（0，0.17）vs. 0.12（0，0.25）］，number of positive targeted biopsy cores［2.0（1.0，3.0）vs. 3.0（1.0，4.0）］，percentage of positive targeted biopsy cores［0.37（0.24，0.75）vs. 0.50（0.38，0.85）］，level of the index lesion，location of the index lesion，and PI-RADS score were associated with pathological upgrading（ P < 0.05）. Multivariate logistic regression analysis showed that PI-RADS score 4（ OR = 5.88，95% CI 2.41 - 14.35），number of suspicious lesions on MRI（ OR = 4.15，95% CI 1.88 - 9.17），location of the index lesion in the transition zone（ OR = 6.86，95% CI 2.81 - 16.73），and percentage of positive targeted biopsy cores（ OR = 4.37，95% CI 1.38 - 14.90）were independent risk factors for pathological upgrading（ P < 0.05）. The nomogram model constructed using these predictors had an AUC of 0.845. Internal validation using the Bootstrap method yielded an AUC value of 0.812，indicating high predictive accuracy of the model. The calibration curve indicated good calibration. Decision curve analysis showed that the threshold range for net benefit in the model was between 12% - 100%. Conclusions:The PI-RADS score 4，the number of lesions with PI-RADS ≥ 3，the location of the main lesion in the transition zone，and the percentage of positive needles in targeted biopsy are independent risk factors for pathological upgrading from Gleason score 3 + 3. The nomogram model constructed from these factors demonstrates good predictive performance and provides a reference for clinical decision-making.
