Objective: To explore the association between takeout fast foods and sugar sweetened beverage consumption with co-occurrence of anxiety and depressive symptoms among first year junior high school students in Yunnan Province, so as to provide theoretical basis for the prevention of anxiety and depressive symptoms co-occurrence among adolescents. Methods: A random cluster sampling involving 8 500 first year junior high school students in 11 counties in Yunnan Province was conducted by a questionnaire survey from October to December 2022. The Depression Anxiety Stress Scale-21 (DASS-21) was applied to assess anxiety and depressive symptoms in first year junior high school students. Chi-square test was used to compare the anxiety-depression co-occurrence symptoms of first year junior high school students with different demographic characteristics. The association between takeout fast foods and sugar sweetened beverage consumption with co-occurrence of anxiety and depressive symptoms of adolescents was analyzed by binary Logistic regression models. Results: The detection rate of co-occurrence of anxiety and depression symptoms among first year junior high school students in Yunnan Province was 26.92%. After controlling for demographic variables and other confounders, takeout fast foods and sugar sweetened beverage consumption( OR=1.50, 95%CI =1.27-1.77) was associated with anxiety-depression co-occurrence symptoms among first year junior high school students in Yunnan Province ( P <0.01). Stratified analysis showed that both Han ( OR=1.37, 95%CI =1.07-1.77) and ethnic minorities ( OR=1.60, 95%CI =1.29-2.00) exhibited statistically significant associations between takeout fast foods and sugar sweetened beverage consumption with co-occurrence of anxiety and depressive symptoms(both P <0.05). Conclusions Takeout fast foods and sugar sweetened beverage consumption increases the risk of co-occurrence of anxiety and depressive symptoms among first year junior high school students in Yunnan Province. It is recommended to strengthen guidance on the consumption of such products among junior high school students to prevent co-occurrence of anxiety and depressive symptoms.

ObjectiveTo prepare triptolide-Chuanxiong Rhizoma extract ethanol transfersomes（TP-CX@TESs）， conduct its quality evaluation， and investigate its in vitro anti-inflammatory efficacy and the underlying mechanisms. MethodsTP-CX@TESs was prepared via the ultrasonic injection method. With encapsulation efficiency and particle size as evaluation indicators， Box-Behnken design-response surface methodology（BBD-RSM） was employed to optimize the formulation process. The TP-CX@TESs prepared under the optimal process was characterized and evaluated for in vitro transdermal performance. A lipopolysaccharide（LPS）-induced RAW264.7 cell inflammation model was established. After 24 h of drug intervention， the levels of inflammatory factors such as nitric oxide（NO）， interleukin-6（IL-6）， and tumor necrosis factor-α（TNF-α） in the cell supernatant were detected. Western blot was used to determine the protein expression levels of Janus kinase 2（JAK2）， signal transducer and activator of transcription 3（STAT3）， and α7 nicotinic acetylcholine receptor（α7nAChR）， and real-time fluorescence quantitative polymerase chain reaction（Real-time PCR） was applied to measure the mRNA expression levels of JAK2， STAT3， the encoding gene of α7nAChR（CHRNA7）， and nuclear transcription factor-κB（NF-κB）. ResultsResults of BBD-RSM showed that the optimal formulation for preparing TP-CX@TESs was as follows：egg yolk lecithin content of 2.3%， ethanol volume fraction of 30%， and ratio of polysorbate-80 to egg yolk lecithin of 2∶5. Microscopic characterization revealed that TP-CX@TESs exhibited a spherical-like structure with a particle size of （105.60±3.85） nm， a polydispersity index of 0.19±0.03， and a Zeta potential of （-15.89±0.98） mV. The encapsulation efficiencies of triptolide， ferulic acid， and ligustilide were （76.88±4.40）%， （78.84±4.40）%， and （65.88±0.06）%， respectively. Both in vitro release and transdermal penetration of triptolide， ferulic acid， and ligustilide in TP-CX@TESs all followed the first-order kinetic model， showing a certain sustained-release property. Experimental results in RAW264.7 cells indicated that TP-CX@TESs significantly inhibited the release of NO， TNF-α， and IL-6（P<0.01）， remarkably upregulated the protein expression levels of STAT3 and α7nAChR（P<0.01）， increased the mRNA expression level of CHRNA7， and significantly downregulated the mRNA expression level of NF-κB（P<0.05， P<0.01）. ConclusionThe optimized formulation process of TP-CX@TESs is simple and feasible， along with favorable in vitro release property， good transdermal permeability， and excellent in vitro anti-inflammatory activity， the mechanism is related to the inhibition of NF-κB.

A mounting body of research suggests that circRNAs significantly contribute to the develop-ment of myocardial fibrosis.The microarray results of human circular RNA expression profile indicated that circHERC4_041 expression increased in the myocardium of patients with heart failure,RT-qPCR a-nalysis confirmed that the myocardial expression level of circHERC4_041 in individuals with heart failure were considerably elevated compared to that in healthy organ donors.Fluorescence in situ hybridization(FISH)confirmed that circHERC4_041 was abundant in the cytoplasm of human cardiomyocyte AC16.Overexpression of circHERC4_041 in mouse myocardial fibroblasts(mCFs)mediated by adenovirus in-hibited the expression of fibrosis-related proteins in mCFs.Experiments involving cell proliferation,wound healing,and Transwell assays demonstrated that overexpression of circHERC4_041 suppressed the growth and mobility of mCFs(P＜0.001).Sequence analysis results suggested that circHERC4_041 con-tains potential ribosome entry sequence(IRES)and open reading frame(ORF).Western blot confirmed that circHERC4_041 could translate the 516 amino acid HERC4-516aa protein,which was mainly located in the cytoplasm of the cell.Cell functional experiments confirmed that circHERC4_041 inhibited the fi-brotic phenotype of mCFs by specifically translating HERC4-516aa(P＜0.05).The specific interaction between HERC4-516aa and transglutaminase 2(TGM2)was confirmed by IP-MS screening and Co-IP i-dentification.Further results found that the degradation of TGM2 was promoted through proteasome path-way.The overexpression of TGM2 in mCFs facilitated by adenoviral vectors could counteract the suppres-sive effects of HERC4-516aa on the fibrotic phenotype of mCFs.Therefore,this study confirmed that the HERC4-516aa protein translated by circHERC4_041 can specifically bind to TGM2 to inhibit the fibrotic phenotype of myocardial fibroblasts.

Objective·To compare the safety and short-term outcomes of robot-assisted versus laparoscopic-assisted proximal gastrectomy combined with double-flap esophagogastrostomy in the treatment of early upper gastric cancer.Methods·A retrospective cohort study was conducted to analyze the clinical and pathological data of 31 early gastric cancer patients who underwent proximal gastrectomy combined with double-flap esophagogastrostomy for gastrointestinal reconstruction at the Department of Gastrointestinal Surgery,Renji Hospital,Shanghai Jiao Tong University School of Medicine,from September 2023 to March 2024.Based on the surgical approach,patients were divided into the robot-assisted surgery group(robotic group,20 cases)and the laparoscope-assisted surgery group(laparoscopic group,11 cases).General clinical data,intraoperative conditions,and postoperative recovery between the two groups were compared.At the 6-month postoperative follow-up,upper gastrointestinal radiography and esophagogastroscopy were performed to assess anastomotic stricture and gastroesophageal reflux disease.Additionally,the gastric cancer-specific module of the European Organization for Research and Treatment of Cancer(EORTC),Quality of Life Questionnaire-Stomach 22(QLQ-STO22),was used to evaluate the patients' quality of life.Results·The general data of the two groups,including gender,age,preoperative comorbidities,American Society of Anesthesiologists(ASA)classification,Siewert classification,and pathological staging of tumors,showed no statistically significant differences(all P>0.05).All patients successfully underwent the procedure without conversion to open surgery.The time for gastroesophageal anastomosis was significantly shorter in the robotic group compared to the laparoscopic group[(31.09±8.23)min vs(43.73±8.83)min,P<0.001],while there were no statistically significant differences in other intraoperative and postoperative parameters,including operative time,intraoperative blood loss,number of lymph nodes removed,duration of gastric tube placement,time to start a liquid diet,length of postoperative hospital stay,and incidence of postoperative complications(all P>0.05).At the 6-month postoperative follow-up,30 patients completed the follow-up,with one patient lost to follow-up in the robotic group.Upper gastrointestinal radiography and esophagogastroscopy results showed that only one patient in the laparoscopic group developed an anastomotic stricture,while one patient in the robotic group developed grade A and one developed grade B gastroesophageal reflux disease(GERD).In addition,one patient in the laparoscopic group also developed grade B GERD.The incidences of GERD and anastomotic stricture showed no statistically significant differences between the two groups(both P>0.05).EORTC QLQ-STO22 results indicated that the robotic group had significantly lower scores in the dimensions of dysphagia,gastroesophageal reflux,and dietary restrictions,as well as in the total score,compared to the laparoscopic group(all P<0.05).Conclusion·Robot-assisted proximal gastrectomy combined with double-flap esophagogastrostomy is safe and feasible.It shortens anastomosis time and offers potential advantages in postoperative functional recovery and quality of life improvement.

Objective:To investigate the temporal correlation between occupational stress and elevated blood pressure among petroleum workers in Xinjiang.Methods:Based on the Occupational Health Study Cohort of Petroleum Workers (OHSPIW), 1600 petroleum workers in Xinjiang who underwent occupational health examinations from May to June 2015 and December 2017 were selected as the research subjects. The occupational stress of workers was evaluated using the Occupational Roles Questionnaire (ORQ) in the Occupational Stress Inventory-Revised (OSI-R). The blood pressure measurement data of physical examination results were collected. The relationship between the ORQ total score and blood pressure was analyzed using Spearman rank correlation, and the causal time-series relationship between occupational stress and elevated blood pressure over time was analyzed by cross-lagged path analysis modelling.Results:In the baseline data of petroleum workers, the systolic blood pressure (SBP) and diastolic blood pressure (DBP) were 124.00 (119.00, 128.00) and 77.00 (73.00, 82.00) mmHg respectively, with an ORQ total score of 164.00 (154.00, 174.00) points. In the follow-up data, the SBP and DBP were 126.00 (123.00, 128.00) and 78.00 (75.00, 82.00) mmHg respectively, and the ORQ total score was 168.00 (157.00, 181.00) points. The results of the correlation analysis showed that the ORQ total score of petroleum workers was positively correlated with the levels of SBP and DBP ( P<0.05), and the ORQ total score at follow-up was negatively correlated with the baseline levels of SBP and DBP ( P<0.05). The results of the cross-lagged path analysis showed that the path coefficients from the baseline ORQ total score of petroleum workers to the follow-up SBP and DBP levels were statistically significant ( ρ=0.06, 0.06, P=0.032, 0.011). In terms of time sequence, the increase in the ORQ total score preceded the increase in the SBP and DBP levels. Conclusion:The occupational stress of petroleum workers is related to blood pressure, and the increase of occupational stress precedes the change of blood pressure. This correlation may increase the risk of hypertension among petroleum workers.

Objective To analyze the imaging features of cerebral small vessel disease in patients with type 2 diabetes mellitus by multimodal MRI.Methods The clinical data of 160 patients with cerebral small vessel disease admitted to our hospital from January to December 2020 were retrospectively analyzed.According to whether they were complicated with type 2 diabetes mellitus,they were divided into the diabetic group and the non-diabetic group,with 80 cases in each group.Both groups underwent multimodal MRI scans.And the severity of lacunar infarction,the severity of subcortical and periventricular white matter lesions,white matter integral and cerebral microbleeds of patients in the two groups were compared.Results The severity of lacunar infarction(χ2=34.076,P=0.001),subcortical white matter lesions(χ2=25.000,P=0.001),periventricular white matter lesions(χ2=22.895,P=0.001)and white matter integral(t=12.370,P=0.001)of patients in the diabetic group were significantly higher than those in the non-diabetic group.No cerebral microbleeds were detected in either group of patients.Conclusion Patients with cerebral small vessel disease and type 2 diabetes mellitus show characteristic multimodal MRI changes.The increase in the number of lacunar infarction lesions and the aggravation of white matter lesions can be used as the characteristic imaging basis for the diagnosis of type 2 diabetes mellitus related cerebral small vessel disease.

Objective To investigate the clinical significance of the combined screening of thyroid stimulating hormone(TSH)and seven candidate pathogenic genes of congenital hypothyroidism(CH)for CH.Methods 16 645 newborns delivered in Nanjing Women and Children's Healthcare Hospital from July 2022 to July 2023 were performed the screening of TSH.Their DNA was extracted from dried blood spots and the chip capture second-generation sequencing technology was used to detect the candidate pathogenic genes,in-cluding dual oxidase 2(DUOX2),dual oxidase maturation factor 2(DUOXA2),prophet of pit-1(PROP1),thyroid-stimulating hor-mone receptor(TSHR),thyroid peroxidase(TPO),thyroglobulin(TG),and paired box 8(PAX8).The sensitivity,specificity,pos-itive predictive value(PPV),and negative predictive value(NPV)of the screening of TSH,candidate genes,and their combination for CH were analyzed.Results A total of 13 CH patients were screened out based on sensitive thyroid stimulating hormone(sTSH)and free thyroxine(FT4),including 3 patients with hyperthyrotropinemia.Among them,11 were screened out by TSH alone,4 were screened out by candidate genes alone,and 2 were screened out by the combination of TSH and candidate genes.The sensitivity,speci-ficity,PPV,and NPV of TSH for screening CH were 84.62％,99.23％,7.91％,and 99.97％,respectively.The sensitivity,specifici-ty,PPV,and NPV of candidate genes for screening CH were 30.77％,99.87％,15.38％,and 99.87％,respectively.The sensitivity,specificity,PPV,and NPV of the combination of TSH and candidate genes for screening CH were 100％,99.09％,7.88％,and 100％,respectively.The primary mutant gene in the samples with positive candidate genes was DUOX2(85.71％),mainly point muta-tions,among which the c.1588A>T variant was the most common(16.67％).PAX8(14.29％)was the second most common variation,and all of the variation point were c.280G>A.No positive samples for the pathogenic variants of DUOXA2,TSHR,PROP1,TPO,and TG were detected.Conclusion The combined screening of TSH and candidate genes helps to improve the screening efficacy of CH.The genetic etiology of CH in Nanjing area may be mainly the variation of DUOX2 and PAX8 genes.

Objective:To investigate the electron microscopic evaluation results of pre-transplant biopsies of deceased donor kidneys and the corresponding recovery of graft function in recipients after kidney transplantation.Methods:A retrospective analysis was conducted on the clinical data and donor kidney electron microscopy (EM) reports of 196 kidney transplant recipients who underwent pre-implantation kidney biopsies at Renmin Hospital of Wuhan University between October 2020 and June 2023. The ultrastructural pathological features assessed in the pre-transplant kidney biopsy included: the number of glomeruli, the presence of leukocytes and endothelial cells within the glomeruli, the arrangement of capillary loops, abnormalities in podocytes, mesangial cells, mesangial matrix and glomerular basement membrane (GBM), and multilayering of the peritubular capillary basement membrane. Referring to the Mayo Clinic/Renal Pathology Society Consensus Report on the pathological classification, diagnosis, and reporting of glomerulonephritis, the expert consensus on renal biopsy pathology reporting models, and the content of the 2019 Banff Transplant Pathology Meeting, a scoring system was established for ultrastructural pathology of donor kidneys. According to the scores, the recipients were divided into three groups: Group A (total score ≥ 8 points, 94 cases), Group B (total score between 6 and 8 points, 85 cases), and Group C (total score < 6 points, 17 cases). The serum creatinine, estimated glomerular filtration rate (eGFR), and proteinuria at postoperative day 1, day 7, month 1, month 3, month 6, and year 1 were compared among the three groups.Results:Among the 196 donor kidneys, EM examination before transplantation showed the following findings: 19 cases (9.7%) had prominent leukocyte infiltration within the glomeruli, 8 cases (4.1%) had mild leukocyte infiltration, and the remaining 169 cases (86.2%) showed no obvious increase in glomerular leukocytes. Glomerular capillary loop collapse or narrowing was seen in 19 cases (9.7%). Endothelial cell proliferation was observed in 32 cases (16.3%). Homogeneous thickening of the GBM (400-900 nm) was present in 82 cases (41.8%). Foot process effacement ranged from partial to diffuse. Podocyte vacuolar degeneration was seen in 62 cases (32.1%), and podocyte swelling in 10 cases (5.1%). Electron-dense deposits in the mesangial area were observed in 9 cases (4.6%). Mild tubular epithelial swelling was present in 6 cases (3.1%). Only 22 cases (11.2%) showed no multilayering of the peritubular capillary basement membrane, while 174 cases (88.8%) showed 2 to 5 layers of multilayering. All donor glomeruli showed irregular capillary loop arrangement, and the renal interstitium showed scattered inflammatory infiltration and varying degrees of collagen fiber deposition. Group C had significantly higher qualitative proteinuria levels at day 7 and month 1 post-transplantation compared with Groups A and B ( P=0.036, 0.004). There were no statistically significant differences in other renal function indicators among the groups (all P>0.05). Conclusions:Pre-transplant electron microscopy of donor kidneys helps in accurately assessing donor kidney quality and identifying subtle pre-existing pathological changes. It can serve as a reference tool for predicting post-transplant functional recovery. Mild ultrastructural abnormalities in donor kidneys have a relatively controllable impact on long-term graft outcomes.

Objective To analyze the results of newborn screening for galactocerebrosidase(GALC)gene and enzyme activity and pro-vide a basis for the clinical diagnosis and genetic counseling of Krabbe disease.Methods The dried blood samples on filter paper from 12 744 newborns born at Nanjing Women and Children's Healthcare Hospital from March 18,2022 to December 31,2022 were collect-ed.The pathogenic variant sites of GALC gene were detected using the chip capture next-generation sequencing technology and Sanger sequencing was used for family validation.The tandem mass spectrometry was used to determine the enzyme activity of GALC in dried blood spots.The comparison of GALC enzyme activity between the carriers with GALC variants and negative group was conducted using the independent sample t-test.Results Among the 12 744 newborns,315 were identified as the carriers with GALC variants,with a carrier rate of 1/40.The most common variant was c.1901T＞C(269 cases,1/47),followed by c.1592G＞A(12 cases,1/1 062).Four newborns(P1-P4)were found to have two pathogenic variant sites and 2 cases were homozygous variants of c.1901T＞C.Family validation showed that the two variant sites in the four newborns were inherited from their parents,leading to a diagnosis of Krabbe dis-ease.Meanwhile,the family validation of the potential P2 patient's sister revealed that they had the same genotype,and the diagnosis of Krabbe disease was made.A preliminary threshold of 0.42 μmol/(L·h)for the enzyme activity of GALC detected by the tandem mass spectrometry was established based on 200 newborn samples.The GALC enzyme activities of 4 children with Krabbe disease were 0.74,0.21,0.17,and 0.29 μmol/(L·h),respectively.The GALC enzyme activity of the P2 patient's sister was 0.28 μmol/(L·h).Except for the P1 patient,the GALC enzyme activities of the P2,P3,and P4 patients and the P2 patient's sister were reduced,indica-ting a positive result.Conclusion The carrier rate of pathogenic variants in the GALC gene is relatively high,with the hotspot mutation being c.1901T＞C.The estimated prevalence of Krabbe disease is 1/3 186.The screening strategy using genetic testing as the primary screening and enzyme activity testing as the second screening can effectively improve the diagnostic efficiency of Krabbe disease,provi-ding a reference for the clinical diagnosis and genetic counseling of Krabbe disease.
