Objective To explore the incidence and prognosis of citrin deficiency in Maoming,and to understand mutation types and frequency of SLC25A13 gene.Methods A total of 88 322 newborns born in Maoming from April 2022 to January 2025 were selected as research subjects.These specimens were screened using tandem mass spectrometry.Newborns with elevated citrulline levels or suspected clinical symptoms of citrin deficiency were recalled immediately for further genetic confirmation,and treated confirmed cases were followed up.Results Among 88 322 newborns,53 cases were positive for citrulline by tandem mass spectrometry,43 cases were recalled with positive initial screening,23 cases were still positive for citrulline after re-examination.Finally,1 case of neonatal intrahepatic cholestasis caused by citrin deficiency(NICCD)was clinically diagnosed,and 10 cases were diagnosed with SLC25A13 gene,of which 1 case was false negative.Therefore,the total positive predictive value was 18.87％(10/53),and the prevalence rate of NICCD in Maoming was 1/8029(11/88 322).A total of 5 mutation sites were detected in 10 neonates with NICCD gene diagnosis,and the top 3 mutation sites in the order of proportion were:c.852-855delTATG accounted for 65.0％(13/20),c.615+5G>A accounted for 15.0％(3/20),IVS16ins3kb accounted for 10.0％(2/20).Among the 11 cases,1 case refused treatment and died of liver failure,while the remaining 10 cases were developing well after standardized treatment.Conclusion The incidence of neonatal citrin deficiency in Maoming is significantly higher than in other areas.Tandem mass spectrometry enables rapid early detection of citrin deficiency,though false-negative results may occur in individual cases.Combining genetic sequencing can improve diagnostic accuracy,and achieve precise management of inherited metabolic diseases.

With the deepening of the reform of the medical and health system,the high-quality development of public hospitals has put forward higher requirements for the modern management system.This article takes a top-tier hospital in Huai'an as an example to explore the practical path and effectiveness of constructing a target management system for department directors in large public hospitals.The research achieved a comprehensive improvement in management efficiency by building a multi-di-mensional discipline evaluation system,promoting the construction of key specialties,creating a'trinity'medical quality man-agement system,strengthening the construction of quality control centers,and combining personalized target management respon-sibility agreements with the selection mechanism for outstanding department directors.Over the three years of implementation,key indicators of the hospital,such as the number of key specialties,CMI value,proportion of fourth-level surgeries,and average length of stay,have significantly improved.The research shows that this system,through the synergistic effect of goal orientation and performance incentives,effectively promotes the coordinated development of discipline construction,medical quality,and op-erational efficiency,providing a reference management paradigm for public hospitals to transition from scale expansion to connota-tion enhancement.

Objective:To investigate the effect of laparoscopic sleeve gastrectomy (LSG) on weight loss in patients with different degrees of obesity.Methods:A retrospective analysis was performed on 152 patients with obesity who underwent LSG in Affiliated Huaian No.1 People′s Hospital of Nanjing Medical University from March 2019 to May 2022, including 119 females (78.3%) and 33 males (21.7%), with a mean age of (30.9±7.9) years (ranging from 18 to 58 years). The body mass index (BMI) was 30.0-34.9 kg/m 2, 35.0-39.9 kg/m 2 and ≥40.0 kg/m 2 in Ⅰ, Ⅱ and Ⅲ objesity groups respectively ( n=38, 57, 57). The body measurements, biochemical indexes, percentage of excess weight loss (%EWL) and percentage of total weight loss (%TWL) were collected and analyzed before and after surgery at 1, 3, 6, 12 months. Statistical analysis was conducted using SPSS 22.0 software. Results:LSG was successfully implemented in 152 patients. Body weight, BMI, waist circumference, hip circumference, waist-to-hip ratio, liver function, blood glucose and lipid parameters all decreased at each time point of postoperative follow-up, while uric acid increased at 1 month and decreased at 3, 6 and 12 months after surgery and then gradually decreased. At 12 months after surgery, the body weight was (75.9±17.0) kg ( t=15.14, P<0.001), BMI (26.2±3.7) kg/m 2 ( t=14.44, P<0.001), waist circumference (89.0±10.7) cm ( t=9.20, P<0.001), hip circumference 100.6±7.6 cm ( t=12.67, P<0.001), alanine aminotransferase (18.2±16.6) μ/L ( t=2.83, P=0.018), aspartate aminotransferase (15.2±14.2) μ/L ( t=2.84, P=0.018), fasting plasma glucose (4.6±0.5) mmol/L ( t=2.01, P=0.026), triglyceride 1.1±0.5 mmol/L ( t=3.71, P=0.005) and uric acid 340.2±102.7 μmol/L ( t=4.46, P=0.001), all were lower than those before surgery with statistical significance. At 6 months after surgery, the %EWL in Ⅰ, Ⅱ and Ⅲ obesity groups was (92.7±35.5) %, (86.1±16.0) % and (67.5±14.0) % respectively, with statistical significance among the 3 groups ( F=5.38, P=0.010). The %TWL was (20.5±7.4) %, (28.5±5.2) % and (28.9±6.1) % in the three groups respectively, and the overall difference was statistically significant ( F=3.50, P=0.043). At 1 year after surgery, there was no significant difference in %EWL and %TWL among the 3 groups. Conclusions:LSG was effective in treating simple obesity, with improvements of body weight, waist circumference, hip circumference, liver function, blood glucose and lipid and uric acid. In the first 6 months after surgery, %EWL in patients with class Ⅰ obesity was higher than that in patients with class Ⅲ obesity, achieving relatively better weight loss. However patients with class Ⅲ obesity also experienced significant weight loss until 1 year after surgery.

Objective To investigate the clinical characteristics and dosimetric parameters associated with acute hematologic toxicity (AHT) resulting from radiation-induced damage to hematopoietic organs in patients undergoing chemoradiotherapy for cervical cancer and to provide a reference for establishing dose constraints in relevant regions of interest (ROIs) and predicting adverse tissue reactions during the development of clinical treatment plans. Methods A retrospective analysis was conducted on 556 patients with cervical cancer who underwent chemoradiotherapy at our hospital. Univariate (χ² and t-test) and multivariate (binary logistic regression analyses) methods were employed to investigate the association of clinical factors and pelvic dose-volume parameters with grade ≥ 3 AHT in patients with cervical cancer. Clinical factors comprised patients’ age, clinical stage, pathologic stage, whether the patient had received chemotherapy in the radiotherapy cycle of interest, and dose-volume dosimetric parameters V_x and D_mean for pelvic bone marrow (BM) and femoral head (FH) structures. Results The incidence of AHT among the included cases was 30.4% (169/556). Chi-square analysis of the clinical factors revealed that whether the patient had received chemotherapy, patient’s age, and pathologic stage had a significant impact on AHT. Univariate analysis showed that the factors associated with AHT were mean dose, V₅, V₁₀, V₁₅, V₂₀, and V₂₅ of BM and FH; dosimetric parameters such as V₃₅ of FH had a significant impact on the development of AHT. Multivariate logistic regression analysis identified V₁₅ of pelvic BM as an independent risk factor for AHT (P=0.041), with a threshold value of 84.29% as determined by a receiver operating characteristic (ROC) curve. Conclusion Whether a patient had received chemotherapy in the radiotherapy cycle of interest, and patient’s age and pathologic stage can serve as predictors of AHT. V₁₅ of BM is an independent risk factor for AHT development. Therefore, when formulating a treatment plan, it is crucial to ensure that pelvic V₁₅ remains below 84.29% to effectively reduce the incidence of grade ≥ 3 acute bone marrow depression.

Objective:To investigate the role and diagnostic value of miRNA-205 in chronic kidney disease (CKD) patients with vascular calcification.Methods:It was divided into in vitro cell experiment and retrospective cohort study. In vitro experiments were conducted by using rat thoracic aortic smooth muscle cells. Alizarin red staining and calcium content detection were used to detect the calcification of vascular smooth muscle cells (VSMCs). Alkaline phosphatase (ALP) test kit was used to measure ALP activity. Western blotting was used to detect the protein expression levels of osteogenic transcription factors runt-related transcription factor 2 (Runx2), α smooth muscle actin (α-SMA) and smooth muscle-22α (SM-22α) in VSMCs. qRT-PCR was used to detect miRNA-205 and Runx2 expression levels. The double luciferase reporter gene assay was used to verify the targeted relationship between miRNA-205 and Runx2. The non-dialysis patients with CKD 3-5 stage from June 2020 to January 2021 in the Department of Nephrology of Fourth Hospital, Hebei Medical University were selected. According to coronary artery calcium score (CACs), the patients were divided into non-calcification group (CACs=0), mild-moderate calcification group (0 400). Spearman correlation analysis was used to analyze the correlation between miRNA-205 and Runx2 and vascular calcification. Logistic regression model and receiver operating characteristic (ROC) curve analysis were used to analyze the ability of miRNA-205 to predict the vascular calcification in patients with CKD. Results:(1)Compared with the control group, calcium nodules were more, and the calcium content, ALP activity and Runx2 protein level were higher, and the expression levels of miRNA-205, α-SMA and SM-22α were significantly lower in high phosphorus group (all P<0.05). Overexpression of miRNA-205 significantly reduced the calcification of VSMCs and Runx2 protein level, and increased the protein levels of α-SMA and SM-22α (all P<0.05). miRNA-205-5p reduced the activity of luciferase in the wild-type Runx2-3'-end non-coding region plasmid. (2) Eighty CKD patients were enrolled, with age of (57.50±14.93) years old and 49 males (61.3%). The results of comparison of miRNA-205 and Runx2 expression levels in non-calcification group ( n=26), mild- moderate calcification group ( n=30) and severe calcification group ( n=24) showed that, the higher degree of calcification, the lower miRNA-205 expression level and the higher Runx2 mRNA expression level (all P<0.05). miRNA-205 was negatively correlated with CACs ( r=-0.50, P<0.01) and Runx2 was positively correlated with CACs ( r=0.55, P<0.01). Multivariate logistic regression analysis results suggested that miRNA-205 ( OR=0.451, 95% CI 0.122-0.873) was an independent influencing factor of vascular calcification in CKD patients. The area under the ROC curve of miRNA-205 and miRNA-205 combined with Runx2 for predicting vascular calcification were 0.796 (95% CI 0.697-0.859) and 0.924 (95% CI 0.866-0.982), respectively. Conclusions:miRNA-205 inhibits vascular calcification by targeting Runx2 to negatively regulate osteogenetic phenotype transformation of VSMCs and is expected to be an early diagnostic marker of vascular calcification in CKD patients.

OBJECTIVE To reveal the role of the basal forebrain(BF)GABAergic neurons in the regulation of isoflurane anesthesia and to elucidate the underlying neural pathways.METHODS The activity of BF GABAer-gic neurons was monitored during isoflurane anesthesia using a genetically encoded calcium indicator in Vgat-Cre mice of both sexes.The activity of BF GABAer-gic neurons was manipulated by chemogenetic and opto-genetic approaches.Sensitivity,induction time and emer-gence time of isoflurane anesthesia were estimated by righting reflex.The electroencephalogram(EEG)power and burst-suppression were monitored by EEG recording.The effects of activation of GABAergic BF-thalamic reticu-lar nucleus(TRN)pathway on isoflurane anesthesia were investigated with optogenetics.RESULTS The activity of BF GABAergic neurons was generally inhibited during isoflurane anesthesia,obviously decreased during the induction of anesthesia and gradually restored during the emergence from anesthesia.Activation of BF GABAergic neurons with chemogenetics and optogenetics promoted behavioral emergence from isoflurane anesthesia,with decreased sensitivity to isoflurane,delayed induction and accelerated emergence from isoflurane anesthesia.Optogenetic activation of BF GABAergic neurons prom-oted cortical activity during isoflurane anesthesia,with decreased EEG delta power and burst suppression ratio during 0.8%and 1.4%isoflurane anesthesia,respectively.Similar to the effects of activating BF GABAergic cell bod-ies,photostimulation of BF GABAergic terminals in the TRN also strongly promoted cortical activation and behav-ioral emergence from isoflurane anesthesia.CONCLU-SION The GABAergic neurons in the BF is a key neural substrate for general anesthesia regulation that facilitates behavioral and cortical emergence from general anesthe-sia via the BF-TRN pathway.
