OBJECTIVE: To investigate the clinical features and pathogenesis of a child with Stargardt disease caused by variants of ABCA4 gene. METHODS: A child presented at Shenzhen Eye Hospital between September 5, 2020, and April 3, 2023 was selected as the study subject. Clinical data of the child were collected. Whole exome sequencing was performed on peripheral blood samples from the child and his parents. Candidate variants were validated by Sanger sequencing and bioinformatic analysis. This study was approved by the Medical Ethics Committee of Shenzhen Eye Hospital (Ethics No.: 2022KYPJ072). RESULTS: The child was a 10-year-old male presenting with uncorrected visual acuity of 0.1 in both eyes without improvement with refractive correction. Fundus photography showed diffusely distributed yellow-white flecks in the macular region. FAF revealing central hypofluorescence surrounded by a hyperfluorescent ring, and OCT demonstrating significant foveal thinning (right eye: 45 μm; left eye: 50 μm) with ellipsoid zone disruption. Whole exome sequencing and Sanger sequencing revealed that the child has harbored compound heterozygous variants of the ABCA4 gene, namely c.2384G>T (p.Gly795Val) and c.2903G>A (p.Arg968Glu), which were inherited from his phenotypically normal parents and consistent with an autosomal recessive inheritance. This specific combination of the variants was previously unreported. According to the guidelines from the American College of Medical Genetics and Genomics (ACMG) guidelines, both variants were classified as likely pathogenic (PM2_Supporting+PM3+PP3+PP4; PM1+PM2_Supporting+PP3+PP4). CONCLUSION The novel compound heterozygous variants of the ABCA4 gene probably underlay the genetic etiology of Stargardt disease type 1 in this child. Above finding has expanded the mutational spectrum of the ABCA4 gene among the Chinese population and provided further evidence for understanding the genetic heterogeneity and genotype-phenotype correlation of the Stargardt disease.

Objective:To report the clinical efficacy of adjuvant therapy based on pathological results following immunotherapy combined with targeted therapy and sequential curative surgical procedures in patients with initially unresectable hepatocellular carcinoma.Methods:This is a retrospective case series study. Data from 100 patients who underwent adjuvant therapy based on pathological results following immunotherapy combined with targeted therapy and sequential curative surgical procedures with long-term survival were collected from December 2018 to December 2022 at the Faculty of Hepato-Pancreato-Biliary Surgery, First Medical Center, Chinese People′s Liberation Army General Hospital. According to inclusion and exclusion criteria, 47 cases were included, among which patients who met the discontinuation criteria and maintained a drug-free tumor-free status. Thirty-nine male and eight female patients were included, with an age of (54.2±18.8)years(range:38 to 73 years) at initial diagnosis. At the time of initial diagnosis, 43 cases (91.5%) were classified as Barcelona Clinic Liver Cancer stage C. Survival curves were made using Kaplan Meier method.Results:Forty-seven patients underwent R0 resection, all achieved a drug-free tumor-free state through postoperative adjuvant therapy based on pathological examination results. Thirty-six patients(76.6%) maintained a drug-free tumor-free survival status for more than 6 months,28 patients(59.6%) for more than 12 months,and 8 patients(17.0%) for more than 24 months. The longest drug-free tumor-free survival in this cohort reached 48 months. The median follow-up time in this study was 32 months. After diagnosis, the overall survival rates at 1- and 3- years were 97.7%(95% CI:93.4% to 100%) and 90.7%(95% CI:82.5% to 99.8%). The postoperative recurrence-free survival rates at 1- and 3- years were 91.0%(95% CI:83.0% to 99.8%) and 71.3%(95% CI:58.7% to 86.5%). Conclusions:The adjuvant therapy based on pathological results following immunotherapy combined with targeted therapy and sequential curative surgical approach provides long-term survival benefits for patients with initially unresectable hepatocellular carcinoma. Standardized adjuvant therapy maybe sustain long-term tumor-free status,and achieve drug-free tumor-free survival.

Objective:To explore the independent risk factors for the occurrence and aggravation of lower back pain (LBP) in patients with Parkinson′s disease (PD), in order to provide reference for clinical diagnosis and treatment.Methods:A retrospective analysis was conducted on the case data of 309 PD patients who visited the Affiliated Yixing Hospital of Jiangsu University from June 2018 to May 2020. The KING Parkinson′s Disease Pain Scale (KPPS) was used to quantitatively evaluate the LBP of PD patients, who were divided into LBP group and Non LBP group. The general clinical data, PD related data, and imaging data of the two groups were compared and analyzed. Binary logistic regression analysis was used to evaluate independent risk factors for LBP in PD patients. Pearson correlation analysis was conducted between KPPS scores and various factors, and linear regression analysis was used to identify the relevant risk factors that exacerbate LBP in PD patients.Results:Compared with the Non LBP group, the LBP group had lower bone mineral density (BMD) and a lower proportion of patients who engaged in daily exercise. The difference between the two groups was statistically significant (all P<0.05). Compared with the Non LBP group, patients in the LBP group had a longer course of illness, higher stiffness scores, a higher proportion of patients with fluctuating symptoms, higher UPDRS-Ⅲ scores, and a higher proportion of patients with thoracolumbar fascial injury (TLFI) and lumbar sagittal imbalance. The differences between the two groups were statistically significant (all P<0.05). The results of binary logistic regression analysis showed that combined TLFI ( OR=2.773, 95% CI: 1.219-6.309, P=0.015), combined lumbar sagittal imbalance ( OR=4.835, 95% CI: 2.244-10.421, P<0.001), and lower BMD ( OR=2.818, 95% CI: 1.767-4.493, P<0.001) were risk factors for LBP in PD patients. The KPPS score was correlated with BMD and TLFI ( r=-0.146, 0.294, all P<0.05). The linear regression results showed that the merged TLFI ( B=2.271, β=0.285, P<0.001) was positively correlated with KPPS score, indicating a risk factor. Conclusions:The combination of TLFI, lumbar sagittal imbalance, and lower BMD is closely related to the occurrence of LBP in PD patients, and the combination of TLFI is an independent risk factor for exacerbating LBP symptoms. Clinical attention should be paid to the prevention and treatment of TLFI in PD patients.

Objective:To assess the long-term outcome of sequential radical surgery after immune combined with targeted therapy for patients with initially unresectable hepatocellular carcinoma (HCC).Methods:Clinical data of 100 patients with initially unresectable HCC undergoing sequential radical surgery after immune combined with targeted therapy at the Faculty of Hepato-Pancreato-Biliary Surgery of Chinese PLA General Hospital from December 2018 to August 2023 were prospectively collected, including 87 males and 13 females, with a median age of 55 (24-73) years. The pre-treatment tumor staging was determined using the China liver cancer staging (CNLC). The efficacy of immune combined with targeted therapy was accessed using the modified response evaluation criteria in solid tumor (mRECIST). The cycles of immune combined with targeted therapy were analyzed. The tumor residual of resected tissue was analyzed through a standard pathological protocol. The prognosis was analyzed using the Kaplan-Meier method.Results:Upon initial diagnosis, there were 46 cases (46.0%) staged CNLC-Ⅲa and 40 (40.0%) staged CNLC-Ⅲb. There were also 14 cases (14.0%) staged CNLC-Ⅰb, Ⅱa, and Ⅱb who underwent immune combined with targeted therapy due to rupture of tumor or insufficient liver remnant. All patients received a median of 5 (3-28) cycles of immune combined with targeted therapy and underwent radical surgery after successful conversion. According to mRECIST, 14 (14.0%) were determined as complete remission, 63 (63.0%) as partial remission, 18 (18.0%) as stable disease, and 5 (5.0%) as disease progression. Of 24 (24.0%) were defined as pathologically complete remission by postoperative pathology. Furthermore, pathological tumor residue was less than 10% in 61 (61.0%) cases and less than 50% in 82 (82.0%) cases. The 1, 3, and 5 year-overall survival rates of patients were 98.0%, 83.1%, and 74.5%, respectively. The 1, 2 and 3 year-recurrence-free survival rates were 67.5%, 54.8%, and 49.6%, respectively.Conclusion:Sequential radical surgery after immune combined with targeted therapy benefits the long-term survival of patients with initially unresectable HCC.

Objective:To investigate the causal association between immune cell and different types of sepsis by using Mendelian randomization (MR) method, and to find the immune cell phenotypes causally associated with sepsis.Methods:Summary data for various circulating immune cell phenotypes were obtained from the GWAS catalog (GCST90001391-GCST90002121). Sepsis data were sourced from the UK Biobank database. Single nucleotide polymorphisms (SNP) were used as instrumental variables. The correlation threshold of P < 5×10 -6 was used to identify the strongly correlated instrumental variables, and the code was used to remove the linkage disequilibrium and the instrumental variables with F-value < 10. Inverse variance weighting (IVW) was used as the main research method to evaluate the stability and reliability of the results, including Cochran's Q test, MR-Egger regression and Leave one out. Reverse MR analysis was performed based on the immunophenotypic results of the removal of horizontal pleiotropy, and the immune cell phenotype with one-way causal association was obtained. Odds ratio ( OR) and 95% confidence interval (95% CI) were used to represent the effect value of the results. Results:CD16 on CD14 -CD16 + monocyte had horizontal pleiotropy in sepsis ( OR = 0.965?4, 95% CI was 0.933?5-0.998?3, P = 0.039?6). There were five immunophenotypes that had reverse causal associations with the types associated with sepsis. After excluding immune cell phenotypes with horizontal pleiotropy and reverse causation, a total of 42 immune cell phenotypes with sepsis, 36 immune cell phenotypes with sepsis (28-day death in critical care), 32 immune cell phenotypes with sepsis (critical care), 44 immune cell phenotypes with sepsis (28-day death), and 30 immune cell phenotypes had potential causal associations with sepsis (under 75 years old). After false discovery rate (FDR) correction, the correlations between BAFF-R on IgD - CD38br and sepsis (28-day death) were negative and strong ( OR = 0.737?8, 95% CI was 0.635?9-0.856?0, P = 6.05×10 -5, PFDR = 0.044?2). Conclusion:A variety of immune cell phenotypes may have a protective effect on sepsis, especially BAFF-R on IgD - CD38br expression is negatively correlated with sepsis (28-day death), which provides a new idea for immune modulation therapy in sepsis.

When conducting long-term experimental verification of urine regeneration using ground equipment of manned space water regeneration system,it was found that the ion exchange removal ability of the water regeneration system is also affected when the pre-treatment agent changes.Therefore,the influence behavior and mechanism of pre-treatment agent changes on the ion exchange removal capacity of water regeneration systems were studied through small sample experiments,water quality composition analysis,and other means.The results showed that with the increase of CrO3 content in the pre-treatment agent,the organic acid content in distilled water increased,leading to an increase in the conductivity,an increase in the organic carbon content,and a decrease in pH value of distilled water.Organic acids have low degree of dissociation in water,and their selectivity coefficients are low when exchanging with strong alkaline anion exchange resins.This results in a slow ion exchange rate of the acid ion.As the organic acid content in distilled water increases,the ion exchange band of acid ion widens and shifts backwards,causing resin penetration,resulting in a decrease in the ion exchange removal ability of the water regeneration system.
