Objective To investigate the impact of nutritional risk-based intervention on the quality of life and survival prognosis of patients with the locally advanced pancreatic cancer and undergoing the chemotherapy.Methods A total of 118 patients with the pancreatic cancer and admitted to the Department of Hepatobiliary and Minimally Invasive Surgery,Lincang People's Hospital from April 2021 to April 2024 were selected and randomly divided into the nutritional intervention group and the control group,with 59 patients in each group.All patients received the palliative chemotherapy,and the control group received the routine dietary guidance,while the intervention group received the nutritional intervention based on the nutritional risk score.The nutritional status,quality of life score,and survival prognosis of the two groups were compared.Results The NRS2002 score of the intervention group and the control group gradually increased from the first to the sixth chemotherapy,and the NRS2002 score of the intervention group was lower than that of the control group at the 4th,5th,and 6th chemotherapy(P<0.05).The incidence of malnutrition in the intervention group was lower than that of the control group at the 1st,2nd,and 3rd chemotherapy(11.9%,30.9%,and 32.2%,respectively),but there was no significant difference(P>0.05);The incidence of malnutrition in the intervention group was significantly lower than that of the control group at the 4th,5th,and 6th chemotherapy(32.2%,45.8%,and 52.5%,respectively),while the incidence of malnutrition in the control group was 59.3%,69.5%,and 88.5%,respectively(P<0.05);The quality of life score of the intervention group in all dimensions was significantly higher than that of the control group after the treatment(P<0.05).After the nutritional intervention,the median OS time and median PFS time of the patients were significantly improved(P<0.05).Conclusion Nutritional intervention can reduce the nutritional risk during the chemotherapy for locally advanced pancreatic cancer patients and improve their quality of life.

Background Exposure to air pollutants increases the risk of diseases in multiple systems, including respiratory and cardiovascular systems, yet its association with neurological diseases remains unclear. Objective To quantitatively evaluate the association between short-term exposure to air pollutants and outpatient and emergency visits for neurological diseases, identify potential susceptible populations, and quantify associated disease burden. Methods Daily 24-hour average concentrations of fine particulate matter (PM_2.5), inhalable particulate matter (PM₁₀), sulfur dioxide (SO₂), nitrogen dioxide (NO₂), and carbon monoxide (CO), daily maximum 8-hour average concentration of ozone (O₃), daily meteorological data (24-hour average temperature, 24-hour average relative humidity), and data on daily outpatient and emergency department visits for neurological diseases from two hospitals in Conghua District, Guangzhou, China, were collected from 2015 to 2022. A time-stratified case-crossover design was adopted, and a conditional Poisson regression model was constructed to analyze the association between air pollution exposure and neurological disease visits. Two-pollutant models and sensitivity analysis were used to validate model stability. Stratified analyses by season (cold season: from November to March; warm season: from April to October), sex (male, female), and age (≤45 years, 46–60 years, ≥61 years) were performed to identify vulnerable group. Additionally, the number and proportion of neurological disease visits attributable to short-term air pollutant exposure were calculated. Results A total of 72 673 outpatient and emergency department visits for neurological diseases were included during the study period. Most of the patients were middle-aged and elderly individuals (69.89% were over 45 years old) and females (60.25%). The results of single-pollutant models showed that for each interquartile range (IQR) increase in exposure to PM_2.5, PM₁₀, SO₂, NO₂, CO, and O₃, the risk of outpatient and emergency department visits for neurological diseases increased by 7.54% (95%CI: 4.69%, 10.46%), 6.66% (95%CI: 3.92%, 9.46%), 16.72% (95%CI: 10.58%, 23.19%), 8.12% (95%CI: 4.82%, 11.53%), 5.60% (95%CI: 2.34%, 8.97%), and 6.11% (95%CI: 2.91%, 9.40%), respectively. The results of the two-pollutant model showed that the association between PM_2.5 and SO₂ exposure and outpatient and emergency department visits for neurological diseases were relatively stable. The stratified analyses showed that the effect of SO₂ was stronger in the cold season. It was estimated that 8.32% (95%CI: 5.55%, 10.96%) and 6.65% (95%CI: 4.27%, 8.96%) of the outpatient and emergency department visits were attributable to short-term exposure to SO₂ and PM_2.5, respectively. Conclusion Exposure to PM_2.5 and SO₂ is associated with increased risks of outpatient and emergency visits for neurological diseases. SO₂ shows stronger effects during the cold season, and exposure to air pollution contributes to up to 8.32% of neurological disease visits.

Objective To compare the short-term clinical outcomes between Natural Orifice Specimen Extraction Surgery(NOSES)and conventional laparoscopic surgery(CLS)for rectal cancer.Methods Clini-cal data of 120 patients with rectal cancer admitted to this hospital from May 2021 to May 2023 were retro-spectively analyzed.They were divided into a NOSES group and a CLS group(60 cases each)according to sur-gical approach.Short-term efficacy of both surgical approaches was analyzed.Results The NOSES group had longer operative time,shorter postoperative hospital stay,and lower incision infection rate than the CLS group(P<0.05).Serum CRP levels in the NOSES group were lower than those in the CLS group on postoperative days 1,3,and 5(P<0.05).VAS scores in the NOSES group were lower than those in the CLS group at 6 hours and days 1-7 postoperatively(P<0.05).The proportion of patients requiring additional dezocine anal-gesia was lower in the NOSES group at 6 hours and days 1-4 postoperatively(P<0.05).CEA levels gradu-ally decreased over time in both groups(P<0.05),but showed no significant intergroup difference(P>0.05).Conclusion Compared with CLS,NOSES has advantages of less postoperative pain,faster recovery,and shorter hospital stay for rectal cancer patients.

Objective:To describe the clinical manifestations, genetic mutation site, diagnosis, and treatment of a patient with multisystem proteinopathy type 1 (MSP1) caused by valosin-containing protein ( VCP) gene mutation, and to improve clinicians′ understanding of this disease. Methods:A retrospective analysis was performed on clinical and genetic data from a confirmed VCP gene missense mutation-associated MSP1 case diagnosed at the Department of Neurology, Affiliated Zhongda Hospital, School of Medicine, Southeast University in January 2024. A 12-month follow-up and systematic literature review were performed for comprehensive analysis. Results:The 53-year-old male patient presented with progressive limb weakness over 7 months. Neurological examination demonstrated tongue fasciculations, asymmetric proximal muscle weakness in all four limbs, left patellar hyperreflexia, positive right Chaddock sign, and bilateral Hoffmann signs. Electrophysiological studies demonstrated extensive neurogenic damage. Lower-limb muscle magnetic resonance imaging (MRI) showed selective fatty infiltration in specific muscle groups. Biceps brachii biopsy pathology revealed rimmed vacuoles and grouped atrophy of typeⅡfibers. Immunofluorescence confirmed aberrant aggregation of VCP within atrophic myofibers, showing co-localization with p62 and transactive response DNA binding protein 43 (TDP-43). Whole-genome sequencing identified a heterozygous c.463C>T (p.Arg155Cys) missense mutation in exon 5 of the VCP gene, classified as a likely pathogenic mutation according to the guidelines of the American College of Medical Genetics and Genomics and the Association for Molecular Pathology. The patient was diagnosed with MSP1 with amyotrophic lateral sclerosis and inclusion body myopathy as the main clinical manifestation based on clinical manifestations, electrophysiology, imaging, histopathology, and genetic findings. After 12 months of riluzole therapy, disease progression remained relatively slow. Literature review identified 67 relevant articles, revealing 87 VCP mutation genotypes and 19 clinical phenotypes. Conclusions:MSP1 is a genetically and phenotypically heterogeneous spectrum of multisystem degenerative disorders. This case represents the first reported VCP-related MSP1 in China, characterized by amyotrophic lateral sclerosis combined with inclusion body myopathy. Riluzole treatment demonstrates slowed disease progression over 1 year.

Hearing loss is the most prevalent disabling disease. Cochlear implantation（CI） serves as the primary intervention for severe to profound hearing loss. This consensus systematically explores the value of genetic diagnosis in the pre-operative assessment and efficacy prognosis for CI. Drawing upon domestic and international research and clinical experience, it proposes an evidence-based medicine three-tiered prognostic classification system（Favorable, Marginal, Poor）. The consensus focuses on common hereditary non-syndromic hearing loss（such as that caused by mutations in genes like GJB2, SLC26A4, OTOF, LOXHD1） and syndromic hereditary hearing loss（such as Jervell & Lange-Nielsen syndrome and Waardenburg syndrome）, which are closely associated with congenital hearing loss, analyzing the impact of their pathological mechanisms on CI outcomes. The consensus provides recommendations based on multiple round of expert discussion and voting. It emphasizes that genetic diagnosis can optimize patient selection, predict prognosis, guide post-operative rehabilitation, offer stratified management strategies for patients with different genotypes, and advance the application of precision medicine in the field of CI.
