Objective:To investigate the injury characteristics, treatment strategy and prognosis of acetabular fracture combined with ipsilateral femoral neck fracture.Methods:A retrospective analysis was conducted of the 15 patients with acetabular fracture combined with ipsilateral femoral neck fracture who had been treated from January 2009 to June 2021 at Department of Orthopaedics, The First Hospital Affiliated to Nanjing Medical University. They were 10 males and 5 females, aged from 26 to 68 years (average, 47.1 years). The treatment strategy depended on their injury characteristics. For the 3 patients with incomplete displacement of the femoral neck fracture but no hip dislocation, the femoral neck fracture was treated by closed reduction and internal fixation; for the 7 patients with complete displacement of the femoral neck fracture but no hip dislocation, the femoral neck fracture was treated first by closed reduction and then by open reduction and internal fixation in case the closed reduction had failed; for the 5 patients complicated with hip dislocation (anterior one in 2 cases and posterior one in 3 cases), the femoral neck fracture was treated by open reduction and internal fixation. The acetabular fractures were treated via an appropriate surgical approach depending on their classifications. The operation time, intraoperative bleeding, fracture healing, functional recovery and complications such as postoperative avascular necrosis of the femoral head (NFH) were recorded.Results:In this cohort, the operation time ranged from 170 to 540 min, averaging 210 min, and the amount of intraoperative bleeding from 300 to 7,900 mL, averaging 800 mL. Postoperative X-ray films showed that all acetabular fractures and femoral neck fractures achieved anatomical reduction or satisfactory reduction. All patients were followed up for 1 to 13 years (average, 4 years). One patient had to receive total hip arthroplasty due to nonunion one year after operation, and the fractures in the other 14 patients healed by the first intention. At the last follow-up by the Merle d'Aubigné & Postel scoring, the function of the hip affected was excellent in 3 cases, good in 6 and poor in 6. NFH occurred in 4 cases, of which one had no hip dislocation and 3 had hip dislocation. Ectopic ossification developed in one patient after operation.Conclusions:The incidence of NFH is high in the patients with acetabular fracture combined with ipsilateral femoral neck fracture, especially higher in those complicated with hip dislocation. Treatment strategies should vary according to the injury characteristics. Attention should be paid to protection of the blood supply to the femoral head which significantly improves the prognosis.

Objective:To compare the effect of reduction and internal fixation of composite acetabular fracture with the modified two-window iliofemoral approach and ilioinguinal approach.Methods:A retrospective cohort study was used to analyze the clinical data of 160 patients with composite acetabular fracture admitted to First Affiliated Hospital of Nanjing Medical University from January 2016 to August 2021, including 117 males and 43 females, aged 15-78 years [(44.1±16.0)years]. According to the Letournel classification system, there were 101 patients with both-column fracture, 5 with anterior wall/column combined with posterior semi-transverse fracture and 24 with T-shaped fracture. A total of 80 patients were treated using the modified iliofemoral incision combined with limited Pfannstiel incision (modified two-window iliofemoral approach group) and the other 80 patients were treated using the ilioinguinal approach (ilioinguinal approach group). The fracture healing was observed. The operation time and intraoperative bleeding volume were compared between the two groups. The quality of fracture reduction was evaluated by Matta scoring standard at 1 day and 6 months after operation. The modified Merle d′Aubigne & Postel scoring standard was used to evaluate the function of the affected hip joint at the last follow-up. The incidence of complications such as neurovascular injury, iatrogenic bladder injury, heterotopic ossification and femoral head necrosis were compared between the two groups.Results:All patients were followed up for 12-78 months [(43.3±17.9)months], with bony union of the fracture. The operation time and intraoperative bleeding volume in modified two-window iliofemoral approach group were 150.0 (123.8, 180.0)minutes and 600.0 (500.0, 787.5)ml when compared to 190.0 (150.0, 240.0)minutes and 700.0 (562.5, 887.5)ml in ilioinguinal approach group (all P<0.01). There was no significant difference between the two groups in the quality of fracture reduction at 1 day and 6 months after operation, function of hip joint at the last follow-up and incidence of complications (all P>0.05). Conclusions:For reduction and internal fixation of composite acetabular fracture, the modified two-window iliofemoral approach has advantages over the ilioinguinal approach in reducing operation time and intraoperative bleeding, although both methods yield similar results in fracture reduction quality, postoperative hip function and complication rate.

Objective:To analyze the impact of gender on prognosis in patients with primary hepatocellular carcinoma (HCC) after hepatectomy.Methods:The data of 1 796 patients with HCC who underwent liver resection at the Guangxi Medical University Cancer Hospital from January 2010 to December 2016 were retrospectively analyzed. There were 1 548 males and 248 females, the average age were 49.6 years. Patients were followed up for recurrence and survival. After propensity score matching, the postoperative survival rates of male and female patients were compared. Univariate and multivariate Cox regression was used to analyze independent factors affecting prognosis of patients with HCC after hepatectomy. The age and menopause were analyzed by subgroup analyses.Results:The 1-, 3- and 5-years cumulative overall and recurrence-free survival rates of male patients were significantly lower than that of female patients (all P<0.05). Multivariate analysis showed that female was an independent protective factor affecting postoperative recurrence ( HR=0.777, 95% CI: 0.615-0.982) and overall survival ( HR=0.669, 95% CI: 0.520-0.856). Using a cut-off value of 50 years old, the patients were divided into <50 years old ( n=915) and ≥50 years old ( n=881). In patients who were less than 50 years old, the 1-, 3- and 5-years cumulative overall and recurrence-free survival rates of male patients were significantly lower than those of female patients (all P<0.05). In patients ≥50 years old, there were no significant difference in the cumulative overall and recurrence-free survival rates between male and female patients (all P>0.05). Female patients were then divided into the postmenopausal group ( n=152) and the premenopausal group ( n=96). There were no significant differences in the cumulative overall and cumulative recurrence-free survival rates between the two groups ( P>0.05). Conclusion:The prognosis of female patients with HCC after hepatectomy was significantly better than that of male patients.

ObjectiveTo investigate the prevalence of overweight or obesity in community patients with schizophrenia in Shanghai and to explore the related factors. MethodsStratified cluster sampling method was used and the general condition， physical examination and laboratory examination data of patients with schizophrenia who voluntarily participated in 2020 free health examination of National Basic Public Health Service were analyzed. ResultsA total of 3 200 patients were included into the study ，and the prevalence of overweight and obesity was 36.75% and 17.19%， respectively. Multivariate logistic regression analysis indicated that age between 40 and 60 （OR=1.333， 95%CI： 1.030‒1.724）， intake of first-generation antipsychotics （OR=1.413， 95%CI： 1.112‒1.796）， intake of second-generation antipsychotics （OR=1.573， 95%CI： 1.288‒1.921）， high-normal blood pressure （OR=1.549， 95%CI： 1.245‒1.927）， high-abnormal blood pressure （OR=2.824， 95%CI： 2.204‒3.619）， elevated ALT （OR=1.874， 95%CI： 1.386‒2.535）， elevated FBG （OR=1.270， 95%CI： 1.066‒1.513）， and elevated TG （OR=1.652， 95%CI： 1.335‒2.044） were the related factors that associated overweight or obesity in patients with schizophrenia. ConclusionOverweight and obesity are highly prevalent among community patients with schizophrenia in Shanghai. Age between 40 and 60， taking first-generation and second-generation antipsychotics， blood pressure higher than 120/80 mmHg， elevated ALT， elevated FBG， and elevated TG are associated with overweight or obesity in patients with schizophrenia. To provide personalized health guidance， medical staff in primary health care institutions should pay more attention to high-risk groups of overweight and obesity in schizophrenia patients at annual physical examination.

We previously identified a unique nucleus, the cerebrospinal fluid (CSF)-contacting nucleus. This study aims to understand its gene architecture and preliminarily suggest its functions. The results showed that there were about 19,666 genes in this nucleus, of which 913 were distinct from the dorsal raphe nucleus (non-CSF contacting). The top 40 highly-expressed genes are mainly related to energy metabolism, protein synthesis, transport, secretion, and hydrolysis. The main neurotransmitter is 5-HT. The receptors of 5-HT and GABA are abundant. The channels for Cl^-, Na⁺, K⁺, and Ca²⁺ are routinely expressed. The signaling molecules associated with the CaMK, JAK, and MAPK pathways were identified accurately. In particular, the channels of transient receptor potential associated with nociceptors and the solute carrier superfamily members associated with cell membrane transport were significantly expressed. The relationship between the main genes of the nucleus and life activities is preliminarily verified.

Pancreatic ductal adenocarcinoma (PDAC) is characterized by the highest mortality among carcinomas. The pathogenesis of PDAC requires elevated autophagy, inhibition of which using hydroxychloroquine has shown promise. However, current realization is impeded by its suboptimal use and unpredictable toxicity. Attempts to identify novel autophagy-modulating agents from already approved drugs offer a rapid and accessible approach. Here, using a patient-derived organoid model, we performed a comparative analysis of therapeutic responses among various antimalarial/fungal/parasitic/viral agents, through which econazole (ECON), an antifungal compound, emerged as the top candidate. Further testing in cell-line and xenograft models of PDAC validated this activity, which occurred as a direct consequence of dysfunctional autophagy. More specifically, ECON boosted autophagy initiation but blocked lysosome biogenesis. RNA sequencing analysis revealed that this autophagic induction was largely attributed to the altered expression of activation transcription factor 3 (ATF3). Increased nuclear import of ATF3 and its transcriptional repression of inhibitor of differentiation-1 (ID-1) led to inactivation of the AKT/mammalian target of rapamycin (mTOR) pathway, thus giving rise to autophagosome accumulation in PDAC cells. The magnitude of the increase in autophagosomes was sufficient to elicit ER stress-mediated apoptosis. Furthermore, ECON, as an autophagy inhibitor, exhibited synergistic effects with trametinib on PDAC. This study provides direct preclinical and experimental evidence for the therapeutic efficacy of ECON in PDAC treatment and reveals a mechanism whereby ECON inhibits PDAC growth.
