BACKGROUND:Studies demonstrated that miR-135a-5p was highly expressed in mouse embryonic palatal mesenchymal cells with cleft palate induced by dexamethasone.The primary cilium and its mediated Shh signaling pathway were involved in the autophagy of mouse embryonic palatal mesenchymal cells.It is speculated that miR-135a-5p may regulate autophagy in mouse embryonic palatal mesenchymal cells through primary cilia and its mediated Shh signaling pathway. OBJECTIVE:To investigate the regulatory effect of miR-135a-5p on autophagy of mouse embryonic palatal mesenchymal cells. METHODS:In vitro,palatal mesenchymal cells from C57BL/6J mouse embryos were extracted and cultured.Cell transfections were set up as follows:(1)the cells were divided into control group,miR-135a-5p negative control group and miR-135a-5p mimic group;(2)NC+miR-NC group,KIF3B overexpression group,and miR-135a-5p+KIF3B group:qRT-PCR was performed to verify transfection efficiency of miR-135a-5p and KIF3B.A transmission electron microscope was used to observe the number of autophagosome/autophagolysosome in the cells of each group.The degree of fluorescence expression of autophagy marker LC3B was determined by the immunofluorescence technique.The protein expression of KIF3B,LC3 and P62 was determined by western blot assay.(3)The cells were divided into miR-135a-5p negative control group,and SAG treated group,and SAG+miR-135a-5p group.qRT-PCR was used to detect the mRNA expression levels of Gli3,a key transcription factor downstream of Shh signaling.The protein expressions of autophagy-related proteins LC3 and P62 were detected by western blot assay. RESULTS AND CONCLUSION:(1)After overexpression of miR-135a-5p,the number of autophagosome/autophagolysosome was significantly increased(P<0.01).The fluorescence density of LC3B increased significantly(P<0.01);the protein expression of KIF3B and P62 decreased(P<0.01),and the protein expression of LC3 increased.(2)After overexpression of KIF3B,the number of autophagosome/autophagolysosome was significantly decreased(P<0.01);the fluorescence density of LC3B was decreased(P<0.01);the protein expression of P62 was increased(P<0.01),and the protein expression of LC3 was decreased(P<0.01).Targeted expression of KIF3B was inhibited by miR-135a-5p(P<0.01);the number of autophagosome/autophagolysosome,the fluorescence intensity of LC3B as well as the protein expression of LC3 were reversed(P<0.01)and the protein expression of P62 was decreased(P<0.01).(3)SAG significantly increased the mRNA expression of Gli3(P<0.01),increased the protein expression of P62(P<0.01),and decreased the protein expression of LC3(P<0.01).When miR-135a-5p was added,Gli3 mRNA expression was significantly decreased(P<0.01);P62 protein expression was decreased(P<0.01),and LC3 protein expression was reversed(P<0.01).(4)These results indicate that miR-135a-5p targets the inhibition of KIF3B and promotes autophagy in mouse embryonic mesenchymal cells possibly by negatively regulating the Shh signaling pathway.

Ankylosing spondylitis (AS) combined with lower cervical fracture is often categorized into unstable fracture, with a high incidence of neurological injury and a high rate of disability and morbidity. As factors such as shoulder occlusion may affect the accuracy of X-ray imaging diagnosis, it is often easily misdiagnosed at the primary diagnosis. Non-operative treatment has complications such as bone nonunion and the possibility of secondary neurological damage, while the timing, access and choice of surgical treatment are still controversial. Currently, there are no clinical practice guidelines for the treatment of AS combined with lower cervical fracture with or without dislocation. To this end, the Spinal Trauma Group of Orthopedics Branch of Chinese Medical Doctor Association organized experts to formulate Clinical guidelines for the treatment of ankylosing spondylitis combined with lower cervical fracture in adults ( version 2024) in accordance with the principles of evidence-based medicine, scientificity and practicality, in which 11 recommendations were put forward in terms of the diagnosis, imaging evaluation, typing and treatment, etc, to provide guidance for the diagnosis and treatment of AS combined with lower cervical fracture.

【Objective】 To analyze the clinical features of patients with infected pancreatic necrosis (IPN) complicated with fungal infection so as to identify possible risk factors for death. 【Methods】 We analyzed the clinical data of patients with IPN admitted to Xuanwu Hospital Capital Medical University from January 1, 2017 to December 31, 2021. According to the results of pancreatic necrotic tissue and drainage fluid culture, the patients were divided into the group with fungal infection and the group without fungal infection. The baseline data, clinical features and outcomes of the two groups were compared, and the risk factors for death in patients with fungal infection were analyzed. 【Results】 We included a total of 214 patients in the study, of whom 49 patients in the fungal infection group had wider necrotic involvement, lower hematopoietic volume, and higher blood glucose at admission. Patients with fungal infection had a higher proportion of multidrug-resistant bacteria (MDRB), and hospital and ICU stay as well as parenteral nutrition duration were also longer. In the group of patients with fungal infection, the proportion of patients undergoing surgery did not increase (P>0.05), but the proportion of patients with perioperative organ failure and death was higher (P<0.05). Candida albicans (44.8%) was the most common fungus detected, followed by Candida parapsilosis (28.6%) and Candida tropicalis (8.2%). Logistic regression analysis showed that MDRB infection (OR=1.37, 95% CI:1.02-1.83), fungemia (OR=1.53, 95% CI:1.06-2.23), hyperglycemia (OR=1.65, 95% CI:1.28-2.10), new organ failure (OR=1.65, 95% CI:1.19-2.29) and bleeding complications (OR=1.64, 95% CI:1.28-2.10) after surgery were risk factors for death in patients with fungal infection. 【Conclusion】 Fungal infection increases mortality in patients with IPN and the incidence of new organ failure after surgery. Attention to fungemia, MDRB infection, hyperglycemia, organ failure and postoperative bleeding can help reduce the risk of death.

@#Objective To investigate the relationship between preoperative mean daily step counts and pulmonary complications after thoracoscopic lobectomy in elderly patients. Methods From 2018 to 2021, the elderly patients with pulmonary complications after thoracoscopic lobectomy were included. A 1∶1 propensity score matching was performed with patients without pulmonary complications. The clinical data were compared between the two groups. Results Totally, 100 elderly patients with pulmonary complications were enrolled, including 78 males and 22 females, aged 66.4±4.5 years. And 100 patients without pulmonary complications were matched, including 71 males and 29 females aged 66.2±5.0 years. There was no significant difference in the preoperative data between the two groups (P>0.05). Compared to the patients with pulmonary complications, the ICU stay was shorter (8.1±4.4 h vs. 12.9±7.5 h, P<0.001), the first out-of-bed activity time was earlier (8.8±4.5 h vs. 11.2±6.1 h, P=0.002), and the tube incubation time was shorter (19.3±9.2 h vs. 22.5±9.4 h, P=0.015) in the patients wihout pulmonary complications. There was no statistical difference in other perioperative data between the two groups (P>0.05). The mean daily step counts in the pulmonary complications group were significantly less than that in the non-pulmonary complications group (4 745.5±2 190.9 steps vs. 6 821.1± 2 542.0 steps, P<0.001). The daily step counts showed an upward trend for three consecutive days in the two groups, but the difference was not significant. Conclusion The decline of preoperative mean daily step counts is related to pulmonary complications after thoracoscopic lobectomy in elderly patients. Recording daily step counts can promote preoperative active exercise training for hospitalized patients.

@#Abstract: The new generation of artificial intelligence technology, represented by deep learning, has emerged as a crucial driving force in the advancement of new drug research and development. This article creatively proposes a workflow named “Molecular Factory” for the design and optimization of drug molecules based on artificial intelligence technology. This workflow integrates intelligent molecular generation models, high-performance molecular docking algorithms, and accurate protein-ligand binding affinity prediction methods. It has been integrated as a core module into DrugFlow, a one-stop drug design software platform, providing a comprehensive set of mature solutions for the discovery and optimization of lead compounds. Utilizing the “Molecular Factory” module, we conducted the research of second-generation inhibitors against Menin that can combat drug resistance. Through the integration of computational and experimental approaches, we rapidly identified multiple promising compounds. Among them, compound RG-10 exhibited the IC50 values of 9.681 nmol/L, 233.2 nmol/L, and 40.09 nmol/L against the wild-type Menin, M327I mutant, and T349M mutant, respectively. Compared to the positive reference molecule SNDX-5613, which has entered Phase II clinical trials, RG-10 demonstrated significantly enhanced inhibitory activity against the M327I and T349M mutants. These findings fully demonstrate the unique advantages of the "Molecular Factory" technology in practical drug design and development scenarios. It can rapidly and efficiently generate high-quality active molecules targeting specific protein structures, holding significant value and profound implications for advancing new drug discovery.

Objective: To investigate the clinicopathological features, molecular genetic features, differential diagnosis and prognosis of ELOC mutated renal cell carcinoma. Methods: From January 2015 to June 2022, 11 cases of renal cell carcinoma with clear-cell morphology, expression of CAⅨ and CK7 and no 3p deletion were collected. Two cases of ELOC mutant renal cell carcinoma were diagnosed using whole exome sequencing (WES). The clinical features, morphology, immunophenotype, FISH and WES results were analyzed. The relevant literature was reviewed. Results: The two patients were both male, aged 29 and 51 years, respectively. They were both found to have a renal mass by physical examination. The maximum diameters of the tumors were 3.5 cm and 2.0 cm, respectively. At the low magnification, the tumors were well-defined. The tumor cells showed a pushing border and were separated by thick fibrous bands, forming nodules. The tumor cells were arranged in a variety of patterns, including tubular, papillary, solid nest or alveolar. At high magnification, the tumor cells were large, with well-defined cell borders and clear cytoplasm or fine eosinophilic granules. CAⅨ was diffusely box-like positive in both cases. Case 1 was partially and moderately positive for CK7, strongly positive for CD10, diffusely and moderately positive for P504S, and weakly positive for 34βE12. In case 2, CK7 and CD10 were both partially, moderately positive and P504s were diffusely positive, but 34βE12 was negative. FISH results showed that both cases had no 3p deletion. ELOC c.235T>A (p.Y79N) mutation was identified using WES in case 1, while ELOC c.236_237inv (p.Y79C) mutation was identified in case 2. Conclusions: As a new clinical entity, ELOC mutated renal cell carcinoma may be underdiagnosed due to its overlap with clear cell renal cell carcinoma in morphology and immunophenotype. The diagnosis of renal cell carcinoma with ELOC mutation should be confirmed by morphology, immunohistochemistry, FISH and gene mutation detection. However, more additional cases are needed to explain its biological behavior and prognosis.
