Objective To investigate the prevalence, distribution characteristics, and influencing factors of mental health problems among the elderly, and to provide a scientific basis for policy-making. Methods A convenience sampling method was used to investigate depression, anxiety, and cognitive function among permanent residents aged 65 and older at 59 mental health care sites for the elderly in Hubei Province. Multinomial logistic regression was employed to analyze influencing factors. Results The screening rates for depression, anxiety, and cognitive function at critical/high-risk levels among the elderly in Hubei Province were 9.7%, 5.4%, and 12.2%, respectively. Urban elderly had lower risks of depression and cognitive function at critical/high-risk levels compared to rural elderly (OR for critical depression = 0.640, P < 0.001; OR for high-risk depression = 0.595, P = 0.012; OR for critical cognitive function = 0.448, P < 0.001; OR for high-risk cognitive function = 0.188, P < 0.001). Six key population groups had higher risks of depression, anxiety, and cognitive function at critical/high-risk levels than others (OR for critical depression = 1.463, P < 0.001; OR for high-risk depression = 1.912, P < 0.001; OR for critical anxiety = 1.462, P < 0.001; OR for high-risk anxiety = 2.882, P < 0.001; OR for critical cognitive function = 1.381, P < 0.001; OR for high-risk cognitive function = 2.345, P < 0.001). A higher number of chronic diseases was associated with increased risks of critical and high-risk depression (OR for critical = 1.316, P < 0.001; OR for high-risk = 3.677, P < 0.001) and cognitive impairment (OR for critical depression = 1.316, P < 0.001; OR for high-risk depression = 3.677, P < 0.001; OR for critical anxiety = 1.512, P < 0.001; OR for high-risk anxiety = 1.801, P < 0.001). Conclusion It is recommended to expand mental health care sites in rural areas, improve the layout of mutual-support elderly care facilities, and explore sustainable models for rural elderly care. Efforts should also focus on enhancing social participation among the elderly through community-based activities, and strengthening cognitive screening and emotional regulation interventions, with particular attention to the mental health needs of older, isolated, and chronically ill individuals.

Objective:To explore the prevalence, clinical features, genetic characteristics and prognosis of Citrin deficiency in Henan province of China.Methods:A total of 986 565 neonates screened by tandem mass spectrometry at the Third Affiliated Hospital of Zhengzhou University from January 2013 to December 2021 were retrospectively analyzed. Analysis of SLC25A13 gene variants and parental verification were carried out for neonates suspected for Citrin deficiency by next-generation sequencing. The clinical, biochemical and genetic characteristics of Citrin deficiency patients were integrated to guide the diet treatment and follow up the growth and development. Paired- t test was used to compare the amino acid levels in the peripheral blood samples before and after the treatment. Results:Nine cases of Citrin deficiency were diagnosed among the 986 565 neonates. Specific elevation of citrulline was observed in all of the 9 cases. Six variants were detected by genetic sequencing, among which c. 852_855delTATG, c. 615+ 5G>A, c. 550C>T and IVS16ins3kb were known pathogenic variants, whilst c. 1111_1112delAT and c. 837T>A were unreported previously. The detection rate for c. 852_855delTATG was the highest (61.6%, 11/18), followed by IVS16ins3kb (16.7%, 3/18). The clinical symptoms of all patients were relieved after the treatment, and the blood amino acid profile and biochemical parameters were significantly improved by gradually falling within the normal range. By June 2022, all patients had shown a good prognosis.Conclusion:The prevalence of Citrin deficiency among neonates from Henan Province by tandem mass spectrometry is 1/109 618, and the carrier rate for the pathogenic variants of the SLC25A13 gene was 1/166. The c. 852_855delTATG may be a hot spot variant among the patients. Discovery of the novel variants has enriched the mutational spectrum of the SLC25A13 gene. Above results have provided a basis for the early diagnosis, treatment, prognosis and genetic counseling for the affected families.

ObjectiveTo investigate the effect of modified Weijingtang on the pyroptosis of RAW264.7 macrophages via the cysteinyl aspartate-specific protease-1 (Caspase-1)/gasdermin D (GSDMD) pathway. MethodLipopolysaccharide (LPS) was used to induce pyroptosis of RAW264.7 cells. The blank group was treated with the blank serum, and the intervention groups were treated with the sera containing different doses of modified Weijingtang. After 24 h, the viability of cells in different groups was examined by the cell counting kit-8 (CCK-8). The pyroptosis and morphology of cells in each group were observed by a scanning electron microscope and a phase-contrast microscope, respectively. The mRNA and protein levels of nucleotide-binding oligomerization domain-like receptor protein 3 (NLRP3), Caspase-1, and GSDMD in each group were determined by real-time fluorescence quantitative polymerase chain reaction (Real-time PCR) and Western blot, respectively. The levels of interleukin (IL)-18 and IL-1β in each group were measured by enzyme-linked immunosorbent assay. ResultUnder the electron microscope, RAW264.7 cells presented the best morphology and structure in the blank group and obvious pyroptosis and leakage of cell contents in the model (LPS) group. Compared with the model group, the intervention groups showed reduced pyroptosis to varying degrees, and the high-dose group had the closest cell morphology and structure to the blank group. Under the optical microscope, RAW264.7 cells were spherical in the blank group and irregular with protrusions in the model group. Compared with the model group, the intervention groups showed improved cell morphology, and the cell morphology in the group with the dose of 20% was the closest to that in the blank group. The mRNA and protein levels of NLRP3, Caspase-1, and GSDMD in the model group were higher than those in the blank group (P<0.05). Compared with the model group, each intervention group showed down-regulated expression of the above indicators (P<0.05). Compared with the blank group, the model group presented elevated levels of IL-18 and IL-1β (P<0.05), which were lowered in the intervention (10%, 20%) groups (P<0.01). ConclusionModified Weijingtang inhibits the pyroptosis of macrophages by down-regulating the Caspase-1/GSDMD pathway and reducing the release of proinflammatory cytokines.

Objective To explore the clinical efficacy and learning curve of robot-assisted thymectomy via subxiphoid approach. Methods The clinical data of patients with robot-assisted thymectomy surgery via subxiphoid approach performed by the same surgical team in the Department of Thoracic Surgery of Shanghai Pulmonary Hospital from February 2021 to August 2022 were retrospectively analyzed. The cumulative sum (CUSUM) analysis and best fit curve were used to analyze the learning curve of this surgery. The general information and perioperative indicators of patients at different learning stages were compared to explore the impact of different learning stages on clinical efficacy of patients. Results A total of 67 patients were enrolled, including 31 males and 36 females, aged 57.10 (54.60, 59.60) years. The operation time was 117.00 (87.00, 150.00) min. The best fitting equation of CUSUM learning curve was y=0.021 2x3–3.192 5x2 +120.17x–84.444 (x was the number of surgical cases), which had a high R2 value of 0.977 8, and the fitting curve reached the top at the 25th case. Based on this, the learning curve was divided into a learning period and a proficiency period. The operation time and intraoperative blood loss in the proficiency stage were significantly shorter or less than those in the learning stage (P<0.001), and there was no statistical difference in thoracic drainage time and volume between the two stages (P>0.05). Conclusion The learning process of robot-assisted thymectomy via subxiphoid approach is safe, and this technique can be skillfully mastered after 25 cases.

Objective:To explore the prognostic value of lymphocyte subsets in adult hemophagocytic syndrome (HPS).Methods:A total of 172 adult HPS patients diagnosed in 8 medical centers from January 2013 to August 2020 were selected for the study, of whom 87 were male (50.6%, 87/172), and 85 were female (49.4%, 85/172), with 68 survivors and 104 deaths. The clinical data were summarized, and variables such as lymphocyte subsets, immunoglobulin characteristics and fibrinogen were retrospectively analyzed, and the correlation between the mentioned variables and patient prognosis was analyzed. The optimal cut-off values of continuous variables were calculated by MaxStat, and the prognostic factors of HPS patients were screened based on the Cox proportional hazard regression model.Results:The median age of HPS patients was 56 (42, 66) years old, and the 5-year cumulative survival rate was 37.4% (37.4/100). The median age, platelet and albumin were 48 (27, 63) years, 84×10 9/L and 32.3 g/L in the survival group, and 59 years, 45.5×10 9/L, and 27.3 g/L in the death group, respectively. The differences between the two groups was statistically significant ( Z=?3.368, P=0.001; Z=?3.156, P=0.002; Z=?3.431, P=0.001). Patients with differentiated cluster 8+(CD8+)<11.1%, CD3+<64.9%, CD4+>51%, and CD4/CD8 ratio>2.18 had poor prognosis (χ 2=7.498, P=0.023; χ 2=4.169, P=0.041; χ 2=4.316, P=0.038; χ 2=9.372, P=0.002). Multivariable analysis showed that CD4/CD8 ratio, age, fibrinogen and hemoglobin were independent prognostic factors in HPS patients ( HR=2.435, P=0.027; HR=5.790, P<0.001; HR=0.432, P=0.018; HR=0.427, P=0.018). Conclusion:Peripheral blood lymphocyte subsets can be used to evaluate the prognosis of patients with HPS; CD4/CD8 ratio, age, fibrinogen, and hemoglobin are independent prognostic factors in HPS patients.

Objective:To explore the genetic basis for a child featuring tetrahydrobiopterin deficiency and global developmental delay.Methods:Clinical and laboratory examinations were carried out for the child. Genomic DNA of the patient was subjected to high-throughput sequencing to identify genetic variants associated with hyperphenylalaninemia. Candidate variants were verified by Sanger sequencing.Results:The result of blood tandem mass spectrometry showed that the Phenylalanine in the blood was 642.7 μmol/l, and the ratio of Phenylalanine/Tyrosine was 5.42. Analysis of urinary pterin: neopterin 0.09 mmol/mol Cr, biopterin 0.04 mmol/mol Cr, biopterin% 77%, which suggested tetrahydrobiopterin deficiency. The parents of the proband were first cousins. DNA sequencing revealed that the proband has harbored homozygous c. 353A>T variants in exon 2 of the GCH1 gene, for which his great grandmother, grandfather, mother, uncle, father and elder brother were heterozygous carriers with normal phenotype and no clinical symptoms associated with dopa responsive dystonia. Conclusion:The homozygous c. 353A>T variant of the GCH1 gene probably underlay the tetrahydrobiopterin deficiency in this pedigree of consanguineous marriage.
