OBJECTIVE To analyze the differences in chemical components of Gardenia jasminoides before and after processing with ginger， and to evaluate the quality differences among different producing areas. METHODS Ultra-high performance liquid chromatography-tandem time-of-flight mass spectrometry was used to analyze the compositional differences of G. jasminoides before and after processing with ginger. The water content， total ash， and ethanol-soluble extract content of ginger- processed G. jasminoides were determined according to the 2020 edition of Chinese Pharmacopoeia. High performance liquid chromatography was adopted to determine the contents of genipin gentiobioside， geniposide， crocin Ⅰ and crocin Ⅱ in ginger- processed G. jasminoides. RESULTS A total of 49 chemical components were identified from raw G. jasminoides and ginger- processed G. jasminoides， including 14 flavonoids， 15 iridoids， 10 organic acids， 2 alkaloids and 8 other compounds. Among them， 42 components were detected in raw G. jasminoides， 28 in ginger-processed G. jasminoides， and 21 components were common to both. After processing with ginger， raw G. jasminoides lost 21 components （including iridoids， flavonoids， alkaloids， and others）， while 7 chemical components were added （including coumarins， organic acids， organic acid esters， and flavonoids）. For the 15 batches of ginger-processed G. jasminoides， the water content ranged from 5.64% to 7.11%， total ash from 2.92% to 4.87%， and ethanol-soluble extract from 40.61% to 58.02%. The average contents of genipin gentiobioside， geniposide， crocin Ⅰ and crocin Ⅱ were 0.108 7， 0.542 2， 0.565 0， and 0.012 5 mg/g， respectively. CONCLUSIONS After processing with ginger， G. jasminoides loses 21 components， while 7 new components are added. Differences are observed in the water content， total ash， ethanol-soluble extract， and the contents of genipin gentiobioside， geniposide， crocin Ⅰ， and crocin Ⅱ of ginger-processed G. jasminoides from different producing areas. Notably， samples from Fujian exhibit high contents of genipin gentiobioside and ethanol-soluble extract， while samples from Jiangxi have a high content of crocin Ⅰ.

Objective To analyze the core elements of standardized diagnosis of occupational carpal tunnel syndrome (OCTS). Methods Data of first reported OCTS case in Guangdong Province were retrospectively analyzed, including occupational exposure history, clinical manifestations, auxiliary examinations, and on-site occupational health investigation results. Furthermore, standardized diagnostic approaches for such occupational diseases were explored. Results The patient worked in a garment manufacturing enterprise, engaged in fabric cutting. The patient had a occupational history of at least three consecutive years of repetitive right wrist work, holding a 15.2 kg electric cutting tool for a cumulative 6.6 hours per day, with awkward wrist movements repeated 13 times per minute. Clinical symptoms included numbness and reduced muscle strength in the areas of median nerve distribution of the right hand, which were aggravated during work and relieved after rest. Physical examination showed inability of right hand to perform fine motor opposition movements of the thumb with the index, middle, and ring fingers; decreased tactile, pain, vibration, graphesthesia, and kinesthetic sensations below the right wrist; and positive Tinel′s sign over the median nerve at the wrist crease level, Phalen′s test, and reverse Phalen′s test of right wrist. Both wrist high-frequency color Doppler ultrasonography and nerve conduction studies and electromyography indicated damage to the right median nerve. However, only the findings from high-frequency color Doppler ultrasonography of the wrist meet the diagnostic criteria specified in GBZ 336-2025 Diagnostic Standard for Occupational Carpal Tunnel Syndrome. On-site occupational health investigation confirmed that the work involved typical repetitive wrist work, and three co-workers in similar positions exhibited comparable symptoms. The case was ultimately diagnosed as OCTS. Conclusion The definitive diagnosis of OCTS requires comprehensive evaluation of four core elements: a clear occupational exposure history, typical clinical symptoms and signs, characteristic objective examination findings, and quantitative on-site occupational health investigation data. Only when these four elements corroborate each other and non-occupational causative factors are excluded can a definitive diagnosis be made.

Abstract To clarify the service targets, service contents, and safeguard mechanisms of the basic public service program for student vision health management, the study grounded in the current status of child and adolescent myopia prevention and control in China and integrated with the practical experience and innovative practices of Wuhan National Demonstration Area for Student Vision Health Management, takes education as the main thread and schools as the base, consolidating resources from multiple stakeholders including education administrative departments, schools, families, and professional technical service institutions. Centering on four core components—vision health education, monitoring and record keeping, risk prevention and control, and dynamic management, the study constructs a multi tiered basic public service system for vision health management of primary and secondary school students. It further proposes the use of an intelligent management platform and a "three tier color coded early warning" mechanism (red, yellow, blue) to prevent and control student myopia at the source, providing schools with replicable and operable implementation pathways to enhance the level of student vision health management.

Objective To explore the diagnostic value of serum sex hormone binding globulin(SHBG),in-sulin-like growth factor-1(IGF-1)and bone age index(BAI)in girls with precocious puberty(PP).Methods A total of 220 girls with PP who were treated in this hospital from January 2022 to August 2024 were selected as the research subjects.The research subjects were divided into 104 children with central preco-cious puberty(CPP,CPP group)and 116 children with simple premature thelarche(SPT,SPT group)accord-ing to the type of the patients' disease.Another 110 girls with normal physical examination and development during the same period were selected as the control group.The levels of serum SHBG and IGF-1 in each group were determined and BAI was calculated.The diagnostic efficacy of the combined detection of serum SHBG,IGF-1 and BAI for CPP was analyzed through the receiver operating characteristic curve,and the correlation between serum SHBG,IGF-1,BAI and sex hormone indicators in girls with PP was analyzed by Pearson corre-lation analysis.Results The levels of height,basal follicle-stimulating hormone(FSH),basal luteinizing hor-mone(LH),and estradiol(E2)in the CPP group and the SPT group were higher than those in the control group,and the differences were statistically significant(P＜0.05).The serum SHBG levels in the CPP group and the SPT group were lower than those in the control group,and the differences were statistically significant(P＜0.05).The serum IGF-1 and BAI in the CPP group and the SPT group were higher than those in the control group,and the differences were statistically significant(P＜0.05).The area under the curve(AUC)of the three combined diagnoses of PP in girls was 0.941,which was significantly larger than those of IGF-1 and BAI(Z=8.140,9.470,both P＜0.05).The AUC of the three combined diagnoses of CPP in girls was 0.958,which was significantly higher than those of the single tests of serum SHBG,IGF-1,and BAI(Z=2.821,7.363,6.412,all P＜0.05).The levels of serum SHBG in PP of girls were negatively correlated with those of IGF-1,BAI,basal FSH,basal LH and E2(P＜0.05).Serum IGF-1 was positively correlated with BAI,basal FSH and basal LH(P＜0.05),but not correlated with E2(P＞0.05).BAI was positively correla-ted with the levels of basal FSH,basal LH and E2(P＜0.05).Conclusion The combination of serum SHBG and IGF-1 with BAI has certain diagnostic value for PP in girls,especially for the diagnosis of CPP,which is significantly superior to a single test.

Objective To investigate the relationship between serum glucagon-like peptide-1(GLP-1),monocyte chemoattractant protein-1(MCP-1),insulin-like growth factor binding protein-3(IGFBP-3)and glycolipid metabolism,bone metabolism and microvascular complications(MC)in children with type 1 diabe-tes mellitus(T1DM).Methods A total of 211 children with T1DM(T1DM group)admitted to Handan Cen-tral Hospital,Xingtai Traditional Chinese Medicine Hospital,Baoding First Central Hospital and Handan Ma-ternal and Child Health Hospital from January 2021 to February 2023 were selected,patients were divided into MC group(63 cases)and non-MC group(148 cases)according to whether MC was complicated within 1 year,and 108 healthy children who underwent physical examination during the same period were selected as control group.The levels of serum GLP-1,MCP-1,IGFBP-3 and glucose and lipid metabolism indexes[fasting plasma glucose(FPG),fasting insulin(FINS),glycosylated hemoglobin(HbA1c),homeostasis model assessment of insulin resistance(HOMA-IR),total cholesterol(TC),triglyceride(TG),high density lipoprotein cholesterol(HDL-C),low density lipoprotein cholesterol(LDL-C)]and bone metabolism indexes[bone specific alkaline phosphatase(BALP),osteocalcin(OST),type I collagen cross-linked C-terminal peptide(CTX)]were detec-ted.The correlation between serum GLP-1,MCP-1,IGFBP-3 and glucose and lipid metabolism,bone metabo-lism in children with T1DM were analyzed by Pearson and Spearman correlation coefficient.Taking MC in children with T1DM as the dependent variable,the influencing factors were determined by multivariate uncon-ditional Logistic regression model,and the predictive value of serum GLP-1,MCP-1 and IGFBP-3 for MC were analyzed by receiver operating characteristic curve.Results The levels of serum GLP-1,FINS,HDL-C,BALP,OST and CTX in the T1DM group were lower than those in the control group,while the levels of MCP-1,IGFBP-3,FPG,HbA1c,HOMA-IR,TG and LDL-C in the T1DM group were higher than those in the control group,the differences were statistically significant(P<0.05).Serum GLP-1 in children with T1DM was negatively correlated with FPG,HbA1c,HOMA-IR,TG and LDL-C,and positively correlated with FINS,HDL-C,BALP,OST and CTX(P<0.05).MCP-1 and IGFBP-3 were positively correlated with FPG,HbA1c,HOMA-IR,TG and LDL-C,and negatively correlated with FINS,HDL-C,BALP,OST and CTX(P<0.05).Follow-up for 1 year,the incidence of MC in 211 children with T1DM was 29.86%(63/211).Elevated HbA1c,HOMA-IR,LDL-C,MCP-1 and IGFBP-3 were independent risk factors for MC in children with T1DM,and elevated GLP-1 was an independent protective factor(P<0.05).The area under the curve of ser-um GLP-1,MCP-1 and IGFBP-3 combined to predict MC in children with T1DM was 0.919,which was grea-ter than 0.781,0.788 and 0.794 predicted by serum GLP-1,MCP-1 and IGFBP-3 alone(P<0.05).Conclu-sion The decrease of serum GLP-1 level and the increase of MCP-1 and IGFBP-3 levels are related to glyco-lipid metabolism,bone metabolism disorder and MC in children with T1DM,the combined application of ser-um GLP-1,MCP-1 and IGFBP-3 has a good predictive value for MC in children with T1DM.

Objective To investigate the impact of high mobility group box 1(HMGB1)on hydrogen peroxide(H2O2)-induced DNA damage and senescence in lens epithelial cells(LECs)under oxidative stress conditions.Methods Fluorescent quantitative real-time polymerase chain reaction(RT-PCR)technology was used to detect the mRNA expres-sion of HMGB1 in the anterior capsule tissue of patients with age-related cataract(ARC group)and epiretinal membrane(control group).Western blot analysis was employed to examine the changes in the protein expression of HMGB1 in the LEC line SRA01/04 after treatment with varying concentrations of H2O2(0,100,200,and 400 μmol·L-1).The optimal concentration was selected for subsequent establishment of a cellular oxidative damage model.The cultured SRA01/04 cells were divided into three groups:Control(untreated),HA(transfected with the control plasmid HA),and OE-HMGB1 groups(transfected with the HMGB1 plasmid).The mRNA and protein expression levels of HMGB1 were detected by RT-PCR and Western blot.The cultured SRA01/04 cells were divided into three groups:H2O2(treated with 400 μmol·L-1 H2O2),H2O2+HA(transfected with the control plasmid HA and simultaneously treated with 400 μmol·L-1 H2O2),and H2O2+OE-HMGB1 groups(transfected with the HMGB1 plasmid and simultaneously treated with 400 μmol·L-1 H2O2).Immunofluorescence was used to detect DNA oxidative damage in cells from each group.Western blot analysis was per-formed to assess the protein expression levels of phosphorylated histone H2A(γH2A),tumor protein p53(P53),cyclin-dependent kinase inhibitor 1A(P21),and cyclin-dependent kinase inhibitor 2A(P16)in cells from each group.Additional-ly,senescence-associated-β-galactosidase(SA-β-gal)staining was conducted to detect senescent changes in cells from each group.Results RT-PCR results indicated that the relative mRNA expression level of HMGB1 in the anterior capsule tissue of the ARC group was significantly decreased,compared with that in the control group(P＜0.001).Furthermore,in the H2O2-induced oxidative damage model,the relative protein expression level of HMGB1 decreased with the increase of the concentration of H2O2.Both RT-PCR and Western blot analyses revealed that the mRNA and protein expression levels of HMGB1 were both significantly elevated in the OE-HMGB1 group,compared with those in the HA group(both P＜0.001).The immunofluorescence staining results demonstrated that the protein expression of γH2A and the fluorescence intensity in the H2O2+OE-HMGB1 group were significantly decreases,compared with those in H2O2 and H2O2+HA groups(all P＜0.001).SA-β-gal staining results showed that the H2O2+OE-HMGB1 group had significantly less cells stained by SA-β-gal than H2O2 and H2O2+HA(both P＜0.001).Additionally,Western blot analysis revealed that,compared with those in H2O2 and H2O2+HA groups,the relative expression levels of senescence-associated proteins P53,P21,and P16 were significantly decreased in the H2O2+OE-HMGB1 group(all P＜0.01).Conclusion HMGB1 inhibits the accumula-tion of damaging DNA and senescence in LECs by enhancing DNA damage repair capabilities.

Objective:To evaluate the long-term outcomes and predictors of coronary atherosclerotic lesions deemed functionally non-ischemic (quantitative flow ratio(QFR)>0.80) and deferred from intervention.Methods:This study is a post-hoc analysis of the FAVOR Ⅲ China trial, which enrolled 3 825 patients with stable or unstable angina pectoris or with myocardial infarction occurring at least 72 hours prior to screening, between December 5, 2018 and January 9, 2020 from 26 research centers in China. Coronary vessels with QFR>0.80 and without interventional treatment were analyzed in this study. The primary endpoint was 3-year target vessel revascularization. Vessels with revascularization (revascularized group) during follow-up were matched 1∶1 using propensity score matching to comparable vessels without revascularization (non-revascularized group). Multivariate Cox regression analysis was used to identify the risk factors for target vessel revascularization (TVR).Results:A total of 6 212 functionally negative vessels with deferred intervention were included in the final analysis, among which 153 vessels (2.5%) underwent TVR during a 3-year follow-up. Prior to propensity score matching, 6 059 vessels comprised the non-revascularized group. At the vessel level, compared to the non-revascularized group, the revascularized group exhibited a significantly higher proportion of males (79.1% (121/153) vs. 70.2% (4 253/6 059), P=0.018), higher body mass index ((25.6±4.0) kg/m2 vs. (24.3±5.2) kg/m2, P=0.003), and a higher prevalence of hypertension (73.9% (113/153) vs. 65.1% (3 944/6 059), P=0.025). And 152 pairs of vessels were successfully matched. Multivariate Cox regression analysis identified in-stent restenosis lesions ( HR=2.59, 95% CI 1.28-5.23, P=0.008) as an independent risk factor for target vessel revascularization. Conclusions:Coronary lesions classified as functionally non-ischemic at baseline are not entirely stable and may progress to lesions that requiring revascularization over time. In-stent restenosis emerges as a critical independent predictor of revascularization.

Objective:Investigate the impact of calcification on the long-term outcomes of patients with coronary chronic total occlusion (CTO) after percutaneous coronary intervention (PCI).Methods:A retrospective cohort study was conducted. Patients who underwent PCI and had at least one CTO lesion at Fuwai Hospital between January 2010 and December 2013 were consecutively enrolled. Calcification was evaluated by coronary angiography, and patients were divided into two groups: moderate/severe calcification group and non/mild calcification group. Clinical follow-up was completed up to 5 years. Incidence of PCI-related complications and immediate procedural outcomes were compared between two groups, and the primary endpoint was the target lesion failure (TLF) at 5 years after PCI. Clinical follow-up endpoint events were analyzed using Kaplan-Meier survival analysis with log-rank test, and Cox multivariate regression model was used to evaluate the relationship between calcification and TLF.Results:The study included 2 659 CTO patients with an age of (57.2±10.5) years, of whom 442 (16.6%) were female, and among whom 13.5% (360/2 659) had moderate/severe calcification. Compared with the non/mild calcification group, the moderate/severe calcification group had a higher incidence of PCI-related complications (43.2% (156/361) vs. 32.5% (772/2 374), P<0.001) and procedural failure (34.3% (124/361) vs. 24.3% (577/2 374), P<0.001). Additionally, the moderate/severe calcification group showed a higher risk of the primary endpoint event (TLF) during the 5-year follow-up (19.8% vs. 15.3%, log-rank P=0.028). Higher incidence of cardiac death was observed in moderate/severe calcification group (5.7% vs. 2.7%, log-rank P=0.003). Cox multivariate regression analysis revealed that moderate/severe calcified plaques remained an independent risk factor for 5-year TLF after CTO-PCI ( HR=1.34, 95% CI: 1.01-1.79, P=0.043). Conclusion:Compared with CTO patients with non/mild calcification, those with moderate/severe calcification have higher procedural failure and complication rates, as well as poorer long-term prognosis, mainly due to an increase in cardiac death.

Objective:To assess the value of chromosomal microarray analysis (CMA) for the detection of low-level mosaicisms in amniotic fluid samples, and to retrospectively analyze the rare cases of mosaicisms.Methods:Chromosomal karyotype of the fetus was determined by G-banding analysis of cultured amniotic fluid cells. CMA was used to detect copy number variation of fetal chromosomes, and fluorescence in situ hybridization (FISH) was used to determine the proportion of fetal chromosomal mosaicisms in uncultured amniotic fluid cells. Results:Among 825 prenatal samples, 4 cases of true fetal mosaicisms were detected, which yielded an incidence of 0.48%. Two cases were sex chromosomal mosaicisms, and two were autosomal mosaicisms, which involved chromosomes 8 and 9, respectively. All cases were verified by G-banding analysis of cultured amniotic fluid cells, CMA, and/or FISH.Conclusion:CMA has a great value for detecting low-level mosaicisms in amniotic fluid samples, though the positive results need to be verified by other techniques and should be interpreted with caution. The review of rare cases can provide a basis for prenatal genetic counseling.
