Objective: To investigate the current status of benefit finding among young and middle-aged patients with type 2 diabetes mellitus (T2DM) and analyze its influencing factors, so as to provide a reference for improving the level of benefit finding in this population. Methods: From November 2022 to May 2023, young and middle-aged patients with T2DM aged 18-59 years hospitalized in the endocrinology departments of 2 tertiary hospitals in Hengyang City, Hunan Province were selected as survey subjects by a convenience sampling method. Basic demographic information was collected using a general questionnaire survey. Benefit finding, resourcefulness, and stigma were evaluated using the Benefit Finding Scale, the Chinese Version of the Resourcefulness Scale, and the Type 2 Diabetes Stigma Assessment Scale, respectively. A multiple linear regression model was used to analyze the influencing factors of benefit finding among young and middle-aged patients with T2DM. Results: A total of 305 young and middle-aged patients with T2DM were investigated, including 222 males (72.79%) and 83 females (27.21%). There were 231 cases aged 45-59 years, accounting for 75.74%. The scores for benefit finding, resourcefulness, and stigma were (42.86±6.06), (75.12±11.30), and (41.20±10.10), respectively. Multiple linear regression analysis showed that young and middle-aged patients with T2DM who were male (β′=0.088), aged 18-<45 years (β′=0.083), absence of diabetes complications (β′=0.124), and had higher resourcefulness scores (β′=0.679) had higher levels of benefit finding, while patients with higher stigma scores (β′=-0.097) had lower levels of benefit finding. Conclusion The level of benefit finding among young and middle-aged patients with T2DM was moderate, and was related to gender, age, diabetes complications, resourcefulness, and stigma.

Objective To investigate the levels and influencing factors for eye lens dose of interventional radiology workers, and to provide a basis for reasonable and scientific radiation protection. Methods Thermoluminescent eye lens dosimeters were used to monitor the left and right eye lens doses of interventional radiology workers in real time during different surgical positions and varying eye protection conditions. The annual eye lens doses for the operators were estimated based on their yearly workload. The differences in eye lens doses under different conditions were analyzed and the influencing factors were identified. Results For individual interventional operations, the range of personal dose equivalent H_p(3) of the left eye of interventional radiology workers was ( < MDL ~ 418.33) μSv, the median (Q₁, Q₃) was 9.29 ( < MDL, 40.79) μSv, and the mean was 40.79 ± 70.36 μSv. The estimated annual eye lens doses were 4.05 mSv and 17.80 mSv based on the median and mean values of the eye lens dose of a single operation multiplied by average annual frequency of operations per person, respectively. The left eye lens dose was higher than the right eye lens dose of the same operator (Z = −4.24, P < 0.05), and the dose of the right eye lens was strongly positively correlated with that of the left eye lens. The left eye lens dose of the first surgeon was higher than that of the second surgeon in the same operation (Z = −3.10, P < 0.05). The eye lens dose was influenced by operator position (χ² = 9.149, P = 0.002, OR = 8.343), eye protection (χ² = 4.619, P = 0.032, OR = 4.352), and air kerma area product (χ² = 8.032, P = 0.005, OR = 5.488). Conclusion According to the results of this study, a significant portion of interventional operators have eye lens doses that approach or exceed international occupational dose limits. It is recommended to pay attention to the operation frequency of the first operator and the air kerma area product of interventional operation, and strengthen radiation protection and dose monitoring for the eye lens of interventional radiology workers.

Objective To access the current situation of the service capacity of radiation health technical service institutions in Jiangxi Province, analyze the existing problems of these institutions, and provide a scientific basis for standardizing the management of such institutions and improving their service capability. Methods A total of 11 radiation health technical service institutions in Jiangxi Province in the National Occupational Health Technical Service Organization Management Information System were selected as the monitoring objects. During the period from 2022 to 2024, 5-6 technical service institutions were selected each year and comprehensively evaluated and inspected using a checklist formulated by the state. Results Among the 16 quality monitoring results of 11 institutions, 2 (12.5%) were rated as excellent, 12 (75%) as qualified, and 2 (12.5%) as unqualified. The risk level assessment identified 7 (43.75%) high-risk institutions, 9 (56.25%) medium-risk institutions, and 0 (0%) low-risk institutions. Conclusion The overall service capacity of radiation health technical service institutions in Jiangxi Province needs to be improved. Notably, institutions within the health system, such as centers for disease control and prevention, show significant shortcomings in both on-site and laboratory testing capabilities.

BACKGROUND: Premature menopause, defined as natural menopause before age 40, is associated with diminished ovarian reserve. Despite growing concerns regarding environmental pollutants, no large-scale population-based studies have systematically examined the association between urinary polycyclic aromatic hydrocarbon metabolites (UPAHMs) and premature menopause. METHODS: This cross-sectional study analyzed 2001-2020 NHANES data, including urinary levels of six PAH metabolites: 1-naphthol (1-NAP), 2-naphthol (2-NAP), 3-fluorene (3-FLU), 2-fluorene (2-FLU), 1-phenanthrene (1-PHE), and 1-pyrene (1-PYR). Premature menopause was self-reported as natural menopause occurring before age 40. Multivariable logistic regression assessed UPAHMs' association with premature menopause, with restricted cubic splines (RCS) evaluating nonlinear trends. Subgroup analyses examined demographic interactions. RESULTS: Among 2,565 participants, 662 reported premature menopause. Multivariable logistic regression showed significant associations between elevated urinary levels of 1-NAP (OR: 1.01, 95% CI: 1.00-1.02, P = 0.02), 2-NAP (OR: 1.01, 95% CI: 1.00-1.02, P = 0.02), and 3-FLU (OR: 1.03, 95% CI: 1.01-1.05, P = 0.01) and increased risk of premature menopause. RCS analysis revealed significant nonlinear relationships for 2-NAP, 3-FLU, 2-FLU, 1-PHE, and 1-PYR with premature menopause risk. White participants showed greater susceptibility to UPAHMs. CONCLUSION Elevated UPAHMs, particularly 1-NAP, 2-NAP, and 3-FLU, were linked to higher premature menopause risk, with nonlinear trends observed. White individuals demonstrated greater vulnerability, emphasizing the need for targeted interventions to reduce PAH exposure.

The Janus kinase/signal transducers and activators of transcription (JAK-STAT) control natural killer (NK) cells development and cytotoxic functions, however, whether long non-coding RNAs (lncRNAs) are involved in this pathway remains unknown. We found that miR155HG was elevated in activated NK cells and promoted their proliferation and effector functions in both NK92 and induced-pluripotent stem cells (iPSCs)-derived NK (iPSC-NK) cells, without reliance on its derived miR-155 and micropeptide P155. Mechanistically, miR155HG bound to miR-6756 and relieved its repression of JAK3 expression, thereby promoting the JAK-STAT pathway and enhancing NK cell proliferation and function. Further investigations disclosed that upon cytokine stimulation, STAT3 directly interacts with miR155HG promoter and induces miR155HG transcription. Collectively, we identify a miR155HG-mediated positive feedback loop of the JAK-STAT signaling. Our study will also provide a power target regarding miR155HG for improving NK cell generation and effector function in the field of NK cell adoptive transfer therapy against cancer, especially iPSC-derived NK cells.

Crohn 's disease (CD) is an intestinal inflammatory disease of unknown etiology, the pathophysiological mechanism is still unclear. The enteric nervous system (ENS) is responsible for the autonomous regulation of intestinal function. Therefore, ENS dysfunction may be the core of the pathophysiological mechanism of CD. Here, we review the pathophysiological mechanism by which ENS contributes to the development of CD, with a focus on the role of aberrant histological manifestations of ENS and plexitis in predicting the recurrence of CD following surgery.

Objective:To investigate the value of the five-sectional screening method of the central nervous system（CNS）in early detection of fetal CNS abnormalities during the first trimester.Methods:The data of pregnant women who underwent nuchal translucency（NT）screening at the Affiliated Suzhou Hospital of Nanjing Medical University from September 2018 to September 2023 were retrospectively analyzed. And a five-sectional screening method of CNS was performed in all fetuses at the meantime. The five-sectional screening protocol in the first trimester consists of the mid-sagittal plane of the fetal head，trans-ventricular plane，trans-thalamus plane，axial plane of the fetal head at the posterior fossa level，and the sagittal plane of the fetal spine. All fetuses underwent ultrasound screening during the second trimester and the third trimester sequentially after NT screening. All the ultrasound findings were tracked，and all fetuses were followed up until delivery or after induction. Fetuses with CNS abnormalities found or suspected in the first trimester were reviewed by at least one senior physician，and follow-up examinations were routinely performed after 2 weeks to further confirm the diagnosis or find other abnormalities that may be present.Results:A total of 13 679 fetuses were screened，included 11 415 singleton pregnancies and 1 132 twin pregnancies. Among them，there were 289 cases of missed follow-up and unexplained fetal death，included 263 singleton pregnancies and 13 twin pregnancies. A total of 13 390 fetuses were finally included，among which，35 cases developed CNS abnormalities with 34 cases detected by prenatal ultrasound and 1 case of closed spina bifida missed in prenatal diagnosis，and the detection rate of CNS malformation by prenatal ultrasound was 97.14%（34/35）. Of the 35 fetuses with CNS abnormalities，24 were detected by the CNS five-sectional screening method in the first trimester，with a sensitivity of 68.57%，a specificity of 100%，a positive predictive value of 100%，and a negative predictive value of 99.92%. Among them，there were 2 cases of anencephaly，3 cases of exencephaly and 6 cases of encephalocele were all detected in the first trimester. In addition，6 cases of holoprosencephaly，3 cases of severe ventriculomegaly，2 cases of open spina bifida，and 2 cases of Dandy-Walker malformation were detected in the first trimester. In this study，1 case of agenesis of corpus callosum（ACC），1 case of arachnoid cyst，1 case of lissencephaly，1 case of schizencephaly，and 1 case of mega cisterna magna were not detected in early pregnancy.Conclusions:The fetal five-sectional screening method of CNS in the first trimester has high specificity，positive predictive value and negative predictive value for the detection of fetal CNS abnormalities，but the sensitivity is moderate. The five-sectional screening method for CNS in early pregnancy may be an effective method for early detection of fetal CNS abnormalities.

Objective:To investigate the diagnostic value of fetal cardiac ultrasound view visualization in the first trimester for congenital heart disease（CHD）.Methods:A retrospective analysis was performed on 13 323 singleton fetuses who underwent first-trimester（11-13 +6 weeks）ultrasound screening at the Ultrasound Medicine Center，the Affiliated Suzhou Hospital of Nanjing Medical University from January 2018 to June 2024. Cardiac views including the four-chamber view（4CV），left ventricular outflow tract view（LVOT），and Results:The study group showed significantly higher rates of "poorly visualized" 4CV，LVOT，and 3VT than the control group（2.70% vs. 0.14%， P=0.005；36.49% vs. 4.76%， P<0.001；36.49% vs.2.46%， P<0.001）. The efficacies of combination 1（any view abnormal）and combination 2（any view "poorly visualized" or "abnormal"）were comparable，with AUCs of 0.86 and 0.85（ P=0.424）. The AUCs of combination 3（3VT "poorly visualized" or any view "abnormal"）and combination 4（4CV "poorly visualized" or any view "abnormal"）were 0.88 and 0.86（ P=0.424），all significantly higher than combination 5（LVOT "poorly visualized" or any view "abnormal"，AUC=0.84，all P<0.05）. Conclusions:"Poorly visualized" cardiac views in the first trimester demonstrate good diagnostic efficacy for CHD，particularly when 3VT or 4CV are affected，warranting heightened clinical vigilance for fetal cardiac anomalies.

Objective:To investigate the hepatoprotective effect of N-acetylcysteine(NAC)on rats with liver injury induced by cisplatin and its effect on intestinal flora and the expression of interleukin-6(IL-6),tumor necrosis factor-α(TNF-α),and nuclear factor-kappa B(NF-κB).Methods:Male Sprague-Dawley rats were randomly divided into control group(CG),cisplatin group(CP),and NAC group.The rats in the NAC group were given NAC 15 mg/kg by gavage for 8 consecutive days.At half an hour after intragastric administration on the fifth day,all rats except those in the NC group were given intraperitoneal injection of 8 mg/kg cisplatin to induce acute liver injury.An automatic biochemical analyzer was used to measure the content of aspartate aminotransferase(AST),alanine aminotransferase(ALT),alkaline phosphatase(ALP),and total bilirubin(TBIL);liver index was calculated for the rats;Western blot was used to measure the relative expression levels of NF-κB,IL-6,and TNF-α in liver tissue;the 16S rDNA technique was used to measure and analyze the amplification information of the V3-V4 regions of each sample.Results:Compared with the NC group,the CP group had significant increases in the content of AST,ALT,ALP,and TBIL,while NAC reversed the abnormal liver function caused by cisplatin.Compared with the NC group,the CP group had a sig-nificant increase in liver index(P=0.000),while the NAC group had a significant reduction in liver index compared with the CP group(P=0.007).Compared with the NC group,the CP group had signifi-cant increases in the expression levels of IL-6,TNF-α,and NF-κB,while the NAC group showed reductions in the expression of these genes,with significant differences in the expression of IL-6 and TNF-α(P=0.006 and 0.000).Compared with the NC group,the CP group had a significant increase in the α-diversity index of intesti-nal flora,while compared with the CP group,the NAC group tended to have a reduction in the α-diversity index of intestinal flora.Com-pared with the CP group at the phylum level,the NAC group had an increase in the abundance of Actinobacteria and a reduction in the abundance of Firmicutes.Compared with the CP group at the genus level,the NAC group had a reduction in the abundance of Rumino-coccaceae and increases in the abundance of Bifidobacterium and Allobaculum.Conclusion:NAC can alleviate acute liver injury caused by cisplatin,possibly by downregulating the expression of IL-6,TNF-α,and NF-κB and regulating the abundance and diver-sity of intestinal flora.
