Ankylosing spondylitis is a chronic immunoinflammatory disease that mainly affects the spine and the sacroiliac joint， the mechanism of which is closely related to signaling pathways， such as osteoprotegerin （OPG）/receptor activator of nuclear factor-κB （RANK）/RANK ligand， mitogen-activated protein kinase （MAPK）， Wnt/β-catenin （β-catenin）， phosphoinositide 3- kinase/protein kinase B/mammalian target of rapamycin （PI3K/Akt/mTOR）. Traditional Chinese medicine has the characteristics of multiple components and targets， and is widely used for the treatment of autoimmune diseases due to its low toxicity， strong specificity， and high efficacy. This review found that monomers and compounds of traditional Chinese medicine can exert anti ankylosing spondylitis effects by intervening in the aforementioned signaling pathways， regulating immune inflammatory responses， and inhibiting biological processes such as bone destruction， ectopic osteogenic differentiation， cell apoptosis， and autophagy.

OBJECTIVE: To observe the therapeutic effect of electroacupuncture (EA) in improving early enteral nutrition tolerance in patients with acute pancreatitis (AP) under the concept of accelerated rehabilitation, and to explore the related mechanism based on the changes in autonomic nerve characteristics. METHODS: A total of 42 patients with AP were randomized into an observation group (21 cases, 1 case dropped out) and a control group (21 cases, 1 case dropped out). The control group received standard basic treatment for AP. On the basis of the treatment in the control group, EA was applied in the observation group, bilateral Zusanli (ST36), Yixian point (Extra), Tianshu (ST25), Neiguan (PC6) and Zhongwan (CV12) were selected as the main points, and the supplementary points were selected according to syndrome differentiation. Ipsilateral Zusanli (ST36) and Yixian point (Extra) were connected to EA, using discontinuous wave, in frequency of 2 Hz, 30 min a time, once a day for 6 continuous days. The enteral nutrition tolerance score was observed before treatment and after 3 and 5 days of treatment; the visual analogue scale (VAS) score for abdominal pain was observed before treatment and after 3 days of treatment; the time of reaching the feeding goal and hospital stay was recorded; the levels of C-reactive protein (CRP) and amylase were measured before treatment and after 5 days of treatment; the heart rate variability (HRV) indexes (standard deviation of NN intervals [SDNN], average standard deviation of NN intervals [SDANN], root mean square of successive NN interval differences [rMSSD], low frequency [LF] and high frequency [HF], ratio of low frequency to high frequency [LF/HF]) were monitored in the two groups. RESULTS: After 3 and 5 days of treatment, the enteral nutrition tolerance scores were decreased compared with those before treatment in both groups (P<0.01), the reductions in the observation group were larger than those in the control group (P<0.01). After 3 days of treatment, the VAS scores for abdominal pain were decreased compared with those before treatment in both groups (P<0.01), the reduction in the observation group was larger than that in the control group (P<0.01). The time of reaching the feeding goal and hospital stay in the observation group was shorter than that in the control group (P<0.05). After 5 days of treatment, the CRP and amylase levels were decreased compared with those before treatment in both groups (P<0.01), the reduction of CRP level in the observation group was larger than that in the control group (P<0.01). In the observation group, SDNN, SDANN and LF/HF were lower than those in the control group (P<0.05, P<0.01), while rMSSD was higher than that in the control group (P<0.01). SDNN, SDANN and LF/HF were positively correlated with the enteral nutrition tolerance scores after 3 and 5 days of treatment (P<0.05), while rMSSD was negatively correlated with the enteral nutrition tolerance scores after 3 and 5 days of treatment (P<0.01). CONCLUSION Electroacupuncture can improve enteral nutrition tolerance in patients with AP by regulating autonomic nervous function, alleviating the inflammation, promoting accelerated recovery, and reducing the length of hospital stay.

OBJECTIVE: To investigate the diagnostic efficacy of ^99mTc-MDP three-phase bone scintigraphy (TPBS) combined with C-reactive protein (CRP) for periprosthetic joint infection (PJI). METHODS: The clinical data of 198 patients who underwent revision surgery of artificial joint between January 2017 and January 2024 and received TPBS examination before surgery were retrospectively analyzed. There were 77 males and 121 females with an average age of 63.74 years ranging from 24 to 92 years. There were 90 cases of hip arthroplasty and 108 cases of knee arthroplasty. PJI was diagnosed according to the 2013 American Musculoskeletal Infection Society (MSIS) standard diagnostic criteria. The sensitivity, specificity, accuracy, negative predictive value (NPV), and positive predict value (PPV) were calculated. The receiver operating characteristic (ROC) curve was used to compare the diagnostic performance of the three methods, and the area under curve (AUC) was used to evaluate the diagnostic performance. RESULTS: According to the 2013 MSIS criteria, 116 cases were diagnosed as PJI, and the remaining 82 cases were aseptic loosening. The cases of PJI diagnosed by TPBS, CRP, and TPBS-CRP were 125, 109, and 137 respectively, and the cases of aseptic loosening were 73, 89, and 61 respectively. The sensitivity, accuracy, NPV, and PPV of TPBS-CRP combination in the diagnosis of PJI were higher than those of TPBS and CRP, but the specificity was lower than that of TPBS and CRP. ROC curve analysis further showed that the AUC value of TPBS-CRP combination was better than that of TPBS and CRP. The severity of bone defect and the duration of symptoms in patients with false positive TPBS diagnosis were worse than those in patients with true negative TPBS diagnosis (P<0.05), but there was no significant difference in the survival time of prosthesis between the two groups (P>0.05). Among the patients diagnosed with PJI by TPBS, CRP, and TPBS-CRP, 49, 35, and 54 patients had received antibiotic treatment 2 weeks before diagnosis, respectively. There was no significant difference in the diagnostic accuracy of TPBS and TPBS-CRP before diagnosis between patients treated with and without antibiotics and those not treated (P>0.05). The diagnostic accuracy of antibiotic therapy before CRP diagnosis was significantly lower than that of untreated patients (P<0.05). CONCLUSION TPBS and CRP have limited specificity in differentiating PJI from aseptic loosening. The TPBS-CRP combination diagnostic method can synergize the local bone metabolic characteristics and systemic inflammatory response to achieve higher diagnostic accuracy, but caution should be exercised in patients with severe bone defects and longer symptom duration.

Checkpoint blockade immunotherapy has emerged as a transformative approach in cancer treatment by activating tumor-infiltrating T cells. However, the efficacy of PD-L1 blockade is restricted in "cold" tumors, which are characterized by low immunogenicity, presenting a challenge to immunotherapy. This study introduces an innovative strategy, utilizing cathepsin-cleavable N-(2-hydroxypropyl) methacrylamide (HPMA) polymer-assisted combined photodynamic therapy (PDT) and PD-L1 degradation for the first time, effectively treating T cell-deficient tumors. The degradable main-chain polymer, conjugated with photosensitizer porphyrin, facilitates the accumulation of reactive oxygen species (ROS), triggering immunogenic cell death (ICD) and promoting cytotoxic T lymphocytes (CTLs) infiltration into tumors. Multivalent peptide antagonists of PD-L1 promote PD-L1 degradation in lysosomes through receptor crosslinking, overcoming the adaptive cycling of PD-L1 to the tumor cell surface. These findings demonstrate that polymer-assisted PDT and PD-L1 crosslinking degradation represent a potential novel strategy for anti-tumor immunotherapy, providing valuable tools for expanding immunotherapy applications in immunosuppressive cancers.

Objective:To investigate the incidence characteristics and influencing factors of non-alcoholic fatty liver disease (NAFLD) in rural Uyghur ethnic group residents in Xinjiang Production and Construction Corps and to provide scientific evidence for early identification and prevention of NAFLD for residents.Methods:A total of 10 158 participants were included from the Xinjiang Uygur ethnic group population cohort. A prospective cohort study and Cox proportional hazards regression model analysis were used to explore the influencing factors and clustering of NAFLD, and the dose-response relationship between related biochemical indicators and the risk of NAFLD was studied using a restricted cubic spline.Results:The cumulative incidence rate of NAFLD was 6.9%, and the incidence density of NAFLD was 12.06/1 000 person-years. The incidence density of NAFLD in females was higher than in males (14.72/1 000 person-years vs. 9.17/1 000 person-years, P<0.001). The incidence density of NAFLD gradually increased with age in the total population, both men and women (all P<0.001). In the general population, an education level of junior high school or above was a protective factor for NAFLD, while older age, divorce, widowhood, overweight, obesity, hypertension, increased glomerular filtration rate, decreased HDL-C, increased LDL-C, and increased ALT were risk factors for NAFLD. Estimated glomerular filtration rate (eGFR), HDL-C, LDL-C, and ALT were non-linearly correlated with the incidence of NAFLD, and there was a significant dose-response relationship between them. Only 19.1% of residents had no NAFLD risk factors; over 80.9% had ≥1 NAFLD risk factors. The risk of NAFLD increased with the number of risk factors. Conclusions:The incidence of NAFLD in rural Uygur ethnic group residents in Xinjiang Production and Construction Corps was relatively low, but most residents had one or more risk factors for NAFLD. Prevention and control of NAFLD in this population cannot be ignored. In addition, people of older age, divorced or widowed, low education level, overweight or obese, hypertension, and abnormal eGFR, HDL-C, LDL-C, and ALT were the high-risk groups of NAFLD that need to be paid attention to in this population.

Interferon regulatory factor 1(IRF-1)is a member of the IRF family.It is the first transcription factor to be identified that could bind to the interferon-stimulated response element(ISRE)on the target gene and displays crucial roles in the interferon-induced signals and pathways.IRF-1,as an important medium,has all of the advantages of full cell cycle regulation,cell death signaling transduction,and reinforcing immune surveillance,which are well documented.Current studies indicate that IRF-1 is of vital importance to the occurrence and evolution of multifarious liver diseases,including but not limited to inhibiting the replication of the hepatitis virus(A/B/C/E),alleviating the progression of liver fibrosis,and aggravating hepatic ischemia-reperfusion injury(HIRI).The tumor suppression of IRF-1 is related to the clinical characteristics of liver cancer patients,which makes it a potential indicator for predicting the prognosis and recurrence of liver cancer;additionally,the latest studies have revealed other effects of IRF-1 such as protection against alcoholic/non-alcoholic fatty liver disease(AFLD/NAFLD),cholangiocarcinoma suppression,and uncommon traits in other liver diseases that had previously received little attention.Intriguingly,several compounds and drugs have featured a protective function in specific liver disease models in which there is significant involvement of the IRF-1 signal.In this paper,we hope to propose a prospective research basis upon which to help decipher translational medicine applications of IRF-1 in liver disease treatment.

Objective:To analyze the influencing factors of not achieving textbook outcome (TO) after laparoscopic radical surgery in patients with malignant pancreatic body and tail tumor, and to establish and evaluate a nomogram for predicting the failure to achieve TO.Methods:The clinical data of 111 patients with malignant pancreatic body and tail tumors undergoing laparoscopic radical surgery in the Department of Hepatobiliary and Pancreatic Surgery in Henan Provincial People's Hospital from January 2020 to December 2022 were retrospectively analyzed, including 44 males and 67 females, aged (53.8±14.7) years. All patients were staged TNM I to II, including pancreatic ductal adenocarcinoma ( n=102, 91.9%), pancreatic neuroendocrine tumor ( n=5, 4.5%), and pancreatic intraductal papillary mucinous tumors ( n=4, 3.6%). The patients were randomly divided into a training set ( n=78) and a test set ( n=33) at a ratio of 7∶3. The 78 patients in the training set were further divided into TO group ( n=28) and control group ( n=50, not achieving TO). Based on the univariate and multivariate logistic regression analysis of training set, the influencing factors of failure to achieve TO after laparoscopic radical surgery in patients with pancreatic body and tail tumor were analyzed. A nomogram based on the multi-factors were established to predict the failure to achieve TO. Receiver operating characteristic (ROC) curve, calibration curve, decision curve analysis (DCA) were utilized to evaluate the nomogram. Results:There were significant differences in tumor diameter, positive lymph nodes, operation time and CT value of pancreas between the TO and control groups (all P<0.05). Multivariate logistic regression analysis showed that tumor diameter >4 cm ( OR=9.673, 95% CI: 2.198-42.579), positive lymph node ( OR=5.385, 95% CI: 1.514-19.154), pancreatic CT value ( OR=0.594, 95% CI: 0.392-0.902) were the influencing factors for patients who did not achieve TO (all P<0.05). Based on the results of multiple factors, a nomogram was established to predict the failure to achieve TO after laparoscopic radical surgery. The area under the ROC curve of the nomogram was 0.849 (95% CI: 0.757-0.940) and 0.873 (95% CI: 0.730-1.000) in the training and test sets, respectively. The calibration curve was close to the ideal curve and the predicted results of the nomogram matched well with the actual results. The DCA showed that the nomogram has obvious positive net benefit. Conclusion:The nomogram constructed with tumor diameter > 4 cm, positive lymph nodes and CT value of pancreas for prediction of the patients with pancreatic body and tail malignant tumor after laparoscopic radical surgery did not achieve TO has good performance.

Objective:To compare the therapeutic efficacy of laparoscopic versus open hepatectomy based on three-dimensional image reconstruction in the treatment of hepatocellular carcinoma (HCC) in the central region of liver.Methods:Clinical data of 118 patients with HCC located in the central region of liver undergoing hepatectomy in the People's Hospital of Zhengzhou University from January 2020 to December 2023 were retrospectively analyzed, including 85 males and 33 females, aged (57.5±8.9) years old. According to surgical approach, patients were divided into two groups: the open surgery group ( n=66) and laparoscopic surgery group ( n=52). All patients underwent three-dimensional image reconstruction preoperatively to determine the tumor location and its relationship with the hepatic vessels. The operative duration, intraoperative blood loss, incidence of postoperative complications, postoperative hospital stay, and prognosis were compared between the groups. Results:Compared to open surgery, patients in laparoscopic group were younger [(55±9) years old vs. (59±8) years old], and experienced a longer operative time [212.5 (152.5, 262.3) min vs. 161.5 (135.8, 210.0) min] and a shorter postoperative hospital stay [11.0(9.0, 13.0) d vs. 13.0(11.0, 15.3) d] (all P<0.05). Postoperative pathology indicated that R0 resection was achieved in both groups. The incidence of postoperative complications were comparable between the two groups [34.6% (18/52) vs. 39.4% (26/66), χ2=0.28, P=0.594]. The 1-year and 3-year recurrence-free survivals were 69.7% and 53.0% in laparoscopic group, similar to those in open group (71.2% and 53.8%, respetctively, P=0.953). Conclusion:Laparoscopic hepatectomy based on three-dimensional image reconstruction is safe and feasible for HCC in central region in terms of clinical prognosis. Laparoscopic surgery is also associated with a shorter postoperative hospital stay.

Objective To develop a prognostic model that integrates preoperative imaging,pathological features,and tumor marker indexes for predicting metastasis in sentinel lymph nodes(SLN).Methods The preoperative examination data of 232 breast cancer patients admitted to the First Affiliated Hospital of Zhengzhou University between January 2022 and April 2023 were retrospectively analyzed.The dataset was randomly divided into a training set(174 cases)and a validation set(58 cases)at a ratio of 3∶1.Univariate and multivariate logistic regression analyses were performed to identify independent predictors influencing SLN metastasis.A nomogram was constructed,and its accuracy and clinical applicability were evaluated using receiver operating characteristic(ROC curve)analysis,calibration curve analysis,and decision curve analysis.Results The multivariate analysis revealed that palpability,CA153,calcification,and ALN blood flow signal were identified as independent risk factors for SLN metastasis(P<0.05).These four variables were integrated into a nomogram and plotted on the ROC curve.The area under the curves(AUCs)for the training set and validation set were 0.810(95%CI:0.744～0.876)and 0.737(95%CI:0.606～0.867),respectively,indicating good predictive accuracy as demonstrated by the calibration curve.Conclusion Revised sentence:"Developing a nomogram for preoperative prediction of SLN metastasis in breast cancer patients offers a non-invasive approach for clinical application and serves as a reliable tool to identify breast cancer patients who may not require SLN biopsy,thereby facilitating decisions regarding further axillary lymph node dissection(ALND)and adjuvant therapy.

Objective:To analyze the clinical characteristics of children with systemic lupus erythematosus (SLE) combined with thrombotic microangiopathy (TMA), and clarify the clinical outcomes and related risk factors of pediatric patients through their treatment and follow-up.Methods:This was a single-center retrospective case-control study. Children diagnosed with SLE combined with TMA between January 2017 and January 2023 at Beijing Children′s Hospital, Capital Medical University, were selected as the TMA group, and SLE children without TMA were selected as the control group.According to the prognosis, children in the TMA group were further divided into the good prognosis group and the poor prognosis group.The data of the children were collected, including age, gender, SLE disease activity, clinical presentations at the time of diagnosis and at the time of thrombosis, laboratory examinations, treatment strategies, prognosis, and follow-up results.The chi-square test and Z-test were used for comparison of count data.The t-test was used for comparison of metrological pairing data.The Fisher′s exact test was used to compare the differences between the 2 groups in categorical variables.The univariate Logistic regression was used to analyze the risk factors of poor prognosis. Results:There were 29 cases in the TMA group, and the incidence of TMA accounted for 2.53% of SLE patients; 33 cases were in the control group.The age at diagnosis of TMA was 13 years and 5 months (ranging from 9 years, 1 month and 5 days to 17 years and 4 months).The common clinical manifestations in order of prevalence were renal involvement (28 cases, 96.55%), hematologic involvement (26 cases, 89.66%), serous effusion (17 cases, 58.62%), rash (13 cases, 44.82%), and neurologic involvement (12 cases, 41.38%).Pleurisy or pericarditis, renal involvement and neurological involvement occurred more often in the TMA group than in the control group (17 cases vs.3 cases, 28 cases vs.10 cases, 12 cases vs.3 cases), and the TMA group showed less facial rash and arthritis than the control group (13 cases vs.25 cases, 4 cases vs.17 cases), and the differences were statistically significant (all P<0.05).The Systemic Lupus Erythematosus Disease Activity Index score in the TMA group [(24.14±9.42) scores] was significantly higher than that in the control group [(10.18±9.42) scores], and the difference was statistically significant ( t=3.233, P<0.05).The hemoglobin level, platelet count, and complement C3 level of the children in the TMA group were significantly lower than those in the control group, whereas the double stranded DNA antibody, lactate dehydrogenase, D-dimer, urea, creatinine, ferritin level, and urine protein quantitation were significantly higher than those in the control group, and the differences were statistically significant (all P<0.05).In the TMA group, 5 cases had decreased ADAMTS13 activity, and 5 cases had significantly increased complement C5b9.A total of 15 cases (51.72%) in the TMA group underwent renal biopsy, and 13 of them had combined renal TMA.In the TMA group, 28 patients (96.6%) received hormone therapy, 17 patients received plasma exchange, and 12 patients were treated with immunosuppressants and biologics; 19 patients (65.5%) improved, and 10 patients (34.5%) gave up the treatment due to deterioration of the disease.The urea level and peripheral blood fragmented erythrocyte rate in the good prognosis group were significantly lower than those in the poor prognosis group [(13.18±4.39) mmol/L vs.(21.16±10.14) mmol/L, t=2.975, P=0.006; 8/17 (47.06%) vs.7/7 (100%), χ2=5.929, P=0.015].The univariate Logistic regression analysis showed that the fragmented erythrocyte, ADAMTS13 activity and urea were the independent risk factors for poor prognosis (all P<0.05). Conclusions:SLE patients with moderate-to-severe disease activity, especially children with hemolytic anemia, thrombocytopenia, and renal dysfunction as prominent manifestations, should be alert to the risk of TMA.Early diagnosis and treatment are crucial.
