Objective:To investigate the clinical and genetic variation characteristics of a child with autosomal dominant lateral temporal lobe epilepsy caused by de novo variation of the MICAL1 gene. Methods:Clinical data of the patient with autosomal dominant lateral temporal lobe epilepsy caused by MICAL1 gene variation diagnosed in Children′s Hospital of Soochow University in August 2019 were collected. The whole exome sequencing was performed on the core members of the family, and the characteristics of gene variations were analyzed. Results:The proband, a 10 years and 5 months old boy, was admitted to the hospital because of "intermittent convulsions for 7 years". The clinical manifestations included focal or generalized tonic-clonic seizures and hearing aura, with normal language and intellectual development. No abnormalities were found in the T 1 and fluid attenuated inversion recovery sequences of the cranial 3.0 T magnetic resonance imaging and 3D thin-slice magnetic resonance imaging.Long-range video electroencephalogram showed the distribution of spinous and slow spinous waves in the left frontal and temporal areas. The results of whole exome gene sequencing in the core family members showed heterozygous de novo missense variation in the MICAL1 gene of the proband (NM_022765): c.763G>T(exon6)(p.Val255Leu) that had not been reported. According to American College of Medical Genetics and Genomics and Association for Molecular Pathology guidelines (2015), the mutation was considered potentially pathogenic. The application of antiepileptic drugs was effective in controlling epileptic seizures. Conclusions:Auditory symptoms are main clinical manifestations for the child with autosomal dominant lateral temporal lobe epilepsy. Antiepileptic drugs can effectively control epileptic seizures of the child, and the MICAL1 gene c.763G>T (p.Val255Leu) mutation is the genetic cause of the proband.

Objective To explore the mechanism by which cancer-associated fibroblasts(CAFs)regulate CD13-high expression neutrophil-like myeloid-derived suppressor cell(CD13hi-nMDSC)migration in pancreatic ductal adenocarcinoma(PDAC),so as to provide potential molecular targets and experimental evidences for immunotherapy in patients.Methods CAFs were isolated and purified from pancreatic cancer tissues of 5 PDAC patients.The phenotype and purity of CAFs were identified by immunofluorescence and flow cytometry.The expression of related factors in CAF was detected by quantitative polymerase chain reaction(qPCR)and enzyme-linked immunosorbent assay(ELISA).CAF conditioned medium and myeloid-derived suppressor cell(MDSC)migration system were constructed by Transwell to observe the migration of MDSCs and to study the specific mechanisms by which the aforementioned cytokines participate in regulating the migration of MDSCs.Results The isolated primary CAFs expressed activation biomarkers fibroblast activation protein(FAP)and α-smooth muscle actin(α-SMA),while the human foreskin fibroblasts(HFFs)of control cells did not express FAP and α-SMA.qPCR results showed that the mRNA expression levels of interleukin 6(IL-6),monocyte chemotactic protein 1(MCP-1),and stromal cell-derived factor 1(SDF-1)in CAFs were higher than those in HFFs(all P＜0.01).The contents of IL-6,MCP-1,and SDF-1 in the CAF culture supernatant were significantly higher than those in the HFF culture supernatant(all P＜0.01),and the secretion content increased with the prolongation of culture time.Compared with HFF conditioned medium and regular medium(RPMI 1640),CAF conditioned medium could recruit more total MDSCs and CD13hi-nMDSCs(all P＜0.01).The addition of SDF-1 recombinant protein alone in the culture system could induce the migration of total MDSCs and CD13hi-nMDSCs,and the addition of SDF-1 neutralizing antibodies or C-X-C motif chemokine receptor 4(CXCR4)blocking antibodies could significantly reduce the migration of CD13hi-nMDSCs induced by CAF conditioned medium(all P＜0.01).Although MCP-1 alone could also induce the migration of total MDSCs and CD13hi-nMDSCs,the number of CD13hi-nMDSCs migrating was significantly less than that of the SDF-1 experimental group.The IL-6 recombinant protein did not induce the migration of total MDSCs or CD13hi-nMDSCs.Conclusion CAFs can mediate the migration of total MDSCs and CD13hi-nMDSCs in PDAC through SDF-1/CXCR4 pathway.

Non-small cell lung cancer (NSCLC), a leading cause of cancer-related deaths worldwide, remains a significant clinical challenge despite advances in immune checkpoint inhibitors therapy, with drug resistance persisting as a major obstacle. Palmitoylation, a critical post-translational modification (PTM) primarily catalyzed by palmitoyltransferases of the zinc finger DHHC-type (ZDHHC), has recently demonstrated important implications in NSCLC. This review aims to elucidate the mechanisms and clinical potential of ZDHHC-mediated protein palmitoylation in NSCLC progression and immune escape.

Objective To explore the perioperative safety of video-assisted thoracic surgery (VATS) in Day Care Unit and the risk factors for delayed discharge under centralized management model. Methods The patients with VATS managed by the Day Care Unit of the Drum Tower Hospital Affiliated to Nanjing University Medical School in 2021 were retrospectively collected. The patients’ postoperative data and risk factors for delayed discharge were analyzed. Results A total of 383 patients were enrolled, including 179 males and 204 females with an average age of 46.09±14.82 years. Eleven (2.87%) patients developed grade 3-4 postoperative complications during the hospitalization. Eighteen (4.70%) patients visited unscheduled outpatient clinic within 7 days, and 6 (1.57%) patients were re-hospitalized within 30 days after discharge. The remaining patients had no significant adverse events during the 30-day follow-up. The average length of hospital stay was 2.27±0.35 d. The length of hospital stay was over 48 h in 48 (12.53%) patients. The independent risk factor for delayed discharge was lobectomy or combined resection (OR=3.015, 95%CI 1.174-7.745, P=0.022). Conclusion VATS can be safely conducted under the centralized management in Day Care Unit. The risk factor for delayed discharge is the extent of surgical resection.

Respiratory syncytial virus (RSV) is an enveloped, negative-sense, single-stranded RNA virus of the Orthopneumovirus  genus of the Pneumoviridae family in the order Mononegavirales. RSV can cause acute upper and lower respiratory tract infections, sometimes with extrapulmonary complications. The disease burden of RSV infection is enormous, mainly affecting infants and older adults aged 75 years or above. Currently, treatment options for RSV are largely supportive. Prevention strategies remain a critical focus, with efforts centered on vaccine development and the use of prophylactic monoclonal antibodies. To date, three RSV vaccines have been approved for active immunization among individuals aged 60 years and above. For children who are not eligible for these vaccines, passive immunization is recommended. A newly approved prophylactic monoclonal antibody, Nirsevimab, which offers enhanced neutralizing activity and an extended half-life, provides exceptional protection for high-risk infants and young children. This review provides a comprehensive and detailed exploration of RSV's virology, immunology, pathogenesis, epidemiology, clinical manifestations, treatment options, and prevention strategies.

Objective To determine risk factors of postoperative pulmonary complications within 1 month in patients undergoing thoracic surgery in Day Care Unit.Methods The total of 200 patients routinely scheduled for VATS under centralized management were enrolled in this study.On the postoperative day 1,lung ultrasound(LUS)was conducted by one physician in the ward.The patients received at least once Chest X-ray or CT in outpatient department within 30 days after discharge.The composite of out-of-hospital PPCs,and the value of LUSS in predicting the PPCs was appraised.Furthermore,we identified the perioperative risk factors associated with PPCs in VATS patients.Results Of 200 recruited VATS patients eligible in the Nanjing Drum Tower Hospital,188 participants received LUS examination and finally completed the 30 days follow-up.Of whom,68 patients developed the varied types of PPCs.Multivariable Logistic regression analysis indicated that comorbidity of immune system disease(P = 0.021),lobar resection(P = 0.031)and the postoperative 24 hours LUSS(P = 0.002)were independent risk factors for PPCs within 30 days after VATS.Conclusion Comorbidity of immune system disease,lobar resection and the postoperative 24 h LUSS were independent risk factors for PPCs within 30 days after VATS.

Objective:To investigate the effects of oocyte maturation trigger using follicle-stimulating hormone (FSH) plus human chorionic gonadotropin (hCG) on clinical outcomes of in vitro fertilization/intracytoplasmic sperm injection and embryo transfer (IVF/ICSI-ET) in gonadotropin-releasing hormone agonist (GnRH-a) cycles. Methods:The retrospective cohort study included 682 patients aged up to 40 years with normal ovarian response who underwent IVF/ICSI-ET at Department of Reproductive Medicine, Women and Children's Hospital, Xiamen University School of Medicine between Feburary 2016 and April 2017. Patients were grouped by whether oocyte maturation was triggered with 250 μg recombinant hCG (r-hCG) plus 300 U urinary FSH (uFSH, dual trigger group, n=439) or 250 μg r-hCG alone (r-hCG group, n=243). The main observation indexes were the clinical pregnancy rate and the live birth rate, and the secondary observation indexes were the high-quality embryo rate, the implantation rate, the biochemical pregnancy rate, the abortion rate, etc. Results:There were no statistically significant differences between the two groups in age, infertility duration, body mass index (BMI), anti-Müllerian hormone (AMH), total dosage and duration of gonadotropin (Gn) used, number of embryos transferred (all P>0.05). The live birth rate, the clinical pregnancy rate, the miscarriage rate, the normal fertilization rate, the cleavage rate, the embryo formation rate and the high-quality embryo rate were not significantly different between the two groups (all P>0.05). The implantation rate [40.47% (191/472)] and the biochemical pregnancy rate [64.20% (156/243)] were higher in dual trigger group than in r-hCG group [32.42% (272/893), P=0.003; 55.35% (272/893), P=0.025]. Conclusion:Dual trigger of oocyte maturation with 250 μg r-hCG plus 300 U uFSH has no benefit on the clinical pregnancy rate and the live birth rate, but could improve the implantation rate and the biochemical pregnancy rate in women undergoing short-acting GnRH-a protocol in IVF/ICSI-ET.
