The cerebral blood flow indicators (middle cerebral artery, posterior cerebral artery, anterior cerebral artery, and basilar artery) were significantly changed after the treatment in group A1, A2 and A3 (P<0.05). After the treatment, there were significant differences in comparing the cerebral blood flow indicators between group A1 and B1, A2 and B2, and A3 and B3 (P<0.05).Conclusion Stage treatment withTiao He Ying Wei needling can improve the sleep quality of insomnia patients.

Objective:To explore the epidemiological characteristics, clinical characteristics, treatment strategies and clinical results of non-dislocated hyperextension tibial plateau fracture.Methods:A total of 25 cases of non-dislocated hyperextension tibial plateau fracture patients were collected, including 12 males and 13 females, aged 27-79 years with an average age of 51±15 years. Causes of injury: 18 cases of traffic accident, 2 cases of heavy injury, 5 cases of falling injury. Schatzker classification of tibial plateau fracture: 4 cases of type II, 5 cases of type IV, 13 cases of type V, 3 cases of type VI. Three columns theoretical classification: 4 cases of simple lateral column, 5 cases of simple medial column, 7 cases of medial column+lateral columns, 9 cases of three columns. Preoperative tibial plateau posterior slope angle was -10-0 degrees, average-5.2 degrees. Preoperative MRI showed 5 cases of medial collateral ligament (MCL) injury, 3 cases of posterolateral complex (PLC) complex injury, 2 cases of PLC+ posterior cruciate ligament (PCL) injury and 10 cases of menisci injury. The change of tibial plateau posterior slope angle was more than 10 degrees in patients with ligament injury, 5 patients had a tibial plateau posterior slope angle change more than 15 degrees, 5 patients had a tibial plateau posterior slope angle change more than 10 degrees, and the patients with a tibial plateau posterior slope angle change less than 10 degrees had no ligament injury; 6 patients with simple lateral column or medial column fracture had a ligament injury, 2 patients with medial column+lateral column fracture had a ligament injury, and 2 patients with three column fracture had a ligament injury.Results:All patients were followed up for 12-24 months, with an average of 16.4 months. The operation time was 124±33 min (65-180 min), and the bleeding volume was 106±48 ml (20-200 ml). All patients were treated by open reduction and internal fixation. According to the characteristics of fracture, targeted reduction of articular surface and restoration of lower limb force line were carried out. The plate was placed on the anterior part of tibial plateau to fix the fracture fragment. Evaluation of postoperative fracture reduction: 20 cases were anatomic reduction, 5 cases were good reduction (between 2-5 mm articular surface collapse), and the excellent rate of fracture reduction was 100%. Internal fixation: 4 cases were treated with simple lateral plate, 2 cases with simple medial plate, 15 cases with medial+ lateral plate, 1 case with medial plate+ lateral anchor suture, 1 case with medial plate+ posterior screw, 1 case with lateral plate+ fibular screw, 1 case with medial plate + lateral plate+ lateral anchor suture. The meniscus was repaired in 8 patients, including 5 medial and 3 laterals. The fracture healing time was 3-6 months (mean 3.3 months). The postoperative knee Rasmussen score was 24.9±3.5 (18-29), and the postoperative knee joint mobility was 118°±9° (90°-130°). Superficial infection occurred in 2 patients.Conclusion:The main imaging characteristic of "non-dislocated hyperextension tibial plateau fracture" is the change of tibial plateau posterior slope angle. The injury of single anteromedial column/anterolateral column fracture is easy to combine with the "diagonal" injury, and when the tibial plateau posterior slope angle changes more than 10 degrees, it is easy to be associated with peripheral ligament injury. By using open reduction and internal fixation, restoring the joint articular surface and lower limb force line, repairing the soft tissue structure and ligament, and reconstructing the stability of knee joint, we can achieve satisfactory results.

Objective:To study the effect of diabetes mellitus (DM) on sepsis in patients with pyogenic liver abscess (PLA).Methods:The clinical data of 116 patients with PLA treated in the Affiliated Hospital of Jiangnan University from January 2021 to May 2022 were retrospectively analyzed, including 64 males and 52 females, aged (62.3±12.6) years old. Patients were divided into DM group ( n=56) and non-DM group ( n=60), which were also divided into the sepsis group ( n=29) and the non-sepsis group ( n=87). The clinical features were compared among the groups, the risk factors of PLA complicated with sepsis were analyzed by multivariate logistic regression. Mediation model was used to analyze how DM affects the development of sepsis. Results:Compared with the non-DM group, patients in DM group had higher incidences of hypertension and acute physiology and chronic health evaluation II, a higher proportion of blood neutrophil count, a higher serum levels of triglyceride, urea nitrogen, fasting blood glucose and glycated hemoglobin at admission. The DM group also higher incidences of hypoproteinemia, pleural effusion, and sepsis, with longer hospital stay and higher hospitalization cost (all P<0.05). The levels of hemoglobin, albumin and hematocrit were lower in DM group (all P<0.05). Multivariate logistic regression analysis showed that comorbidity of DM ( OR=3.431, 95% CI: 1.245-9.455) and abscess with a larger diameter ( OR=1.664, 95% CI: 1.258-2.220) were associated with a higher risk of developing sepsis (all P<0.05). Mediation model showed that neutrophil count and triglyceride were the mediating variables of sepsis in patients with PLA. Conclusion:Comorbidity of diabetes is an independent risk factor of developing sepsis in patients with pyogenic liver abscess. Diabetes may induce sepsis by affecting the neutrophils and triglyceride.

Objective:To study the logistic regression model and Chi-square automatic interaction detection decision tree model in the prediction of the recurrence of acute pancreatitis (AP).Methods:Clinical data of 364 patients with AP admitted to the Affiliated Hospital of Jiangnan University from June 2021 to June 2022 were retrospectively analyzed, including 219 males and 145 females, aged 53 (19-91) years. The patients were divided into the recurrence group ( n=63), those who experienced a second or more episodes of AP, and the initial group ( n=301), those who were diagnosed of AP for the first time. Univariate and multivariate logistic regression analyses were performed to identify the factors associated with recurrence of AP, and the decision tree model was used to analyze those factors. Receiver operating characteristic (ROC) curve were plotted to analyze the predictive performance of the two models. Results:Multivariate logistic regression analysis showed that age ( OR=0.969, 95% CI: 0.949-0.990, P=0.004), body mass index ( OR=1.142, 95% CI: 1.059-1.232, P=0.001), and hyperlipidemia ( OR=3.034, 95% CI: 1.543-5.964, P=0.001) were independent factors influencing the recurrence of AP. The accuracy of the model in predicting recurrence was 83.2% (303/364). The decision tree model showed that hyperlipidemia and body mass index were factors influencing the recurrence of AP, with an accuracy of 82.7% (301/364) in predicting recurrence. The area under the ROC curve was larger in the logistic regression model compared to that in the decision tree model (0.776 vs 0.730, Z=2.02, P=0.043). Conclusion:The logistic regression model and the Chi-square automatic interaction detection decision tree model can help predict the recurrence of AP. It is recommended to combine the two models to better guide clinical practice.

Nucleos(t)ide analogues (NUC) can inhibit the replication of hepatitis B virus (HBV) and effectively treat chronic hepatitis B (CHB), but they cannot completely eradicate HBV and cannot prevent the progression to hepatitis B cirrhosis and liver cancer in the context of a low viral load. In recent years, traditional Chinese medicine has been widely used in the treatment of CHB. This article elaborates on the application and mechanism of traditional Chinese medicine in inhibiting HBV replication, reducing the content of HBeAg, and delaying the progression to hepatitis B cirrhosis, and it is proposed that traditional Chinese medicine can improve the therapeutic effect of NUC in the treatment of CHB.

Glycolysis plays an important role in the development and progression of liver diseases and shows varying degrees of enhancement in different liver diseases, and it is closely associated with mitochondrial dysfunction (oxidative phosphorylation deficiency and reactive oxygen species production), which helps to fill energy production deficiency caused by impaired oxidative phosphorylation. Therefore, it might be possible to search for potential new therapies for liver diseases through targeted regulation of the key factors in aerobic glycolysis, such as hexokinase 2, pyruvate kinase M2, and other regulatory pathways. From the perspective of the association between glycolysis and liver diseases, this article elaborates on the therapeutic significance and potential value of glycolysis in liver diseases, in order to provide new ideas for the diagnosis and treatment of liver diseases.

Inflammation is closely associated with the development of cancer. Tumor-associated macrophages (TAM) actively participate in tumor-related inflammation and promote tumor growth and metastasis, while under certain conditions, TAM also show cytotoxicity and tumor killing activity and thus inhibit the progression of cancer. Crosstalk between TAM and neighboring cells is closely associated with the progression of hepatocellular carcinoma (HCC) and drug resistance during treatment. This article summarizes the role of macrophages in HCC and the crosstalk between macrophages and other cells, so as to provide new strategies for the clinical diagnosis and treatment of HCC.

Liver failure is a common end-stage liver disease syndrome in clinical practice characterized by massive necrosis of hepatocytes leading to rapid liver failure, and it is currently believed that excessive inflammation and immune response are the core mechanisms of this disease. Endogenous lipid mediators are involved in the regulation of a variety of inflammatory processes, including initiation, maintenance, and regression, and eicosanoids and pro-decomposition lipid mediators, as well as their complex metabolic pathways and transduction signals, play a key role in the regulation of these processes. This article reviews the key role of endogenous lipid mediators in the pathophysiological mechanism of inflammation and immune dysfunction in liver failure and the potential significance and new therapeutic opportunities of lipid immune pathway in liver failure, in order to provide new ideas for the clinical diagnosis and treatment of liver failure.

BACKGROUND: Epidermal growth factor receptor (EGFR) and cellular-mesenchymal to epithelial transition factor (c-Met) are widely expressed on cancer cells. There is a synergistic effect of EGFR and HGF/c-Met pathways on proliferation, downstream activation of signal transduction and an additive effect. Studies show that combination of both signaling pathways could potentially be targeted in a synergistic fashion. Amivantamab, a bispecific monoclonal antibody targeting EGFR and c-Met, yielded robust and durable responses in a variety of clinicals trials. However, few researches have reported its efficacy in Chinese non-small cell lung cancer (NSCLC) patients. This study was conducted to evaluate the effectiveness and tolerance of Amivantamab in NSCLC patients with EGFR/MET gene abnormalities at Peking University Cancer Hospital. METHODS: The study enrolled NSCLC patients who received Amivantamab in our hospital between August 2020 and December 2021, and analyzed the response, survival, and treatment-related adverse events. RESULTS: Fifteen patients were enrolled in this research, and six of them received Amivantamab treatment and the other nine patients received Amivantamab plus Lazertinib treatment. The rates of partial response (PR), stable disease (SD), and progressive disease (PD) were 46.7% (7/15), 46.7% (7/15) and 6.7% (1/15), respectively. The overall response rate (ORR) and disease control rate (DCR) were 28.6% (2/7) and 100.0% (7/7) in seven patients with EGFR exon 20 insertion, respectively. The ORR and DCR were 40.0% (2/5) and 100.0% (5/5) in five post-osimertinib EGFR-mutant patients, respectively. After a median follow-up of 8.7 months, the median progression-free survival and overall survival were not reached. The most common treatment-related adverse events were rash (86.7%), paronychia (80.0%), and infusion-related reactions (60.0%), and most of them were graded as 1 to 2. Grade 3 to 4 adverse events included rash (33.3%), alanine aminotransferase elevation (13.3%), gamma-glutamyl transpeptidase elevation (13.3%), peripheral edema (6.7%), thromboembolism (6.7%), interstitial lung disease (6.7%), and thrombocytopenia (6.7%). CONCLUSIONS Amivantamab was effective in Chinese NSCLC patients with EGFR exon 20 insertion and post-Osimertinib EGFR-mutant patients, similar to the results of clinical trials conducted in western countries. Amivantamab was well tolerated and emphases should be put on adverse events such as rash, paronychia, and infusion-related reactions.
