Objective To investigate the expression levels of serum hemoglobin β(HBB)in hepatocellular carcinoma(HCC)patients and its correlation with topoisomeraseⅡα(TOP2A)gene.Methods A total of 48 HCC patients visited the Second Affiliated Hospital of Nantong University from August 2023 to September 2024 were selected as the HCC group,and 32 healthy individuals who underwent physical examination during the same period were selected as the healthy control group.Their blood samples were collected,and the ex-pression levels of serum HBB and TOP2A genes were detected by real-time fluorescence quantitative polymerase chain reaction(qRT-PCR).Then,the relationship between the expression of HBB gene and clinicopathological parameters of the patients was ana-lyzed.The Kaplan-Meier Plotter database was used to evaluate the relationship between the expression of HBB gene and the prognosis of HCC.The diagnostic value of the expressions of serum HBB and TOP2A genes for HCC was assessed by the receiver operating charac-teristic(ROC)curve.Spearman rank correlation analysis was used to evaluate the correlation between the expressions of serum HBB and TOP2A genes in HCC patients.The regulatory effect of HBB gene on TOP2A gene was verified by the cell experiment.Results The expression levels of serum HBB gene in HCC patients(0.097[0.055,0.155])were significantly lower than that in healthy controls(1.029[0.625,1.434],U=19,P＜0.001).The expression levels of serum TOP2A gene in HCC patients(1.810[0.825,3.623])were significantly higher than that in healthy controls(1.047[0.604,1.364],U=495,P=0.007).The expression level of serum HBB gene in HCC patients was significantly negatively correlated with that of TOP2A gene(ρ=-0.384,P=0.007).The analysis results of clinicopathological parameters showed that the expression level of HBB gene was only related to tumor size(χ2=4.090,P＜0.05).The Kaplan-Meier survival analysis showed that the 5-year overall survival rate of the patients with low expression of HBB gene was signifi-cantly lower than that with high expression(HR=0.680,95%CI:0.470-0.970,P＜0.05).The analysis of the ROC curve showed that the area under the ROC curve(AUCROC)of HBB gene in diagnosing HCC was 0.987(95%CI:0.963-1.000).When the cut-off value was 0.228,its sensitivity was 100%and specificity was 97%.The AUCROC of TOP2A gene for the diagnosis of HCC was 0.677(95%CI:0.559-0.797).When the cut-off value was 1.285,its sensitivity was 65%and specificity was 75%.The combined detection of HBB and TOP2A genes for the diagnosis of HCC had an AUCROC of 0.988(95%CI:0.965-1.000).When the cut-off value was 0.657,its sensitivity was 100%and specificity was 97%.The cell experiment results showed that the overexpression of HBB gene could inhibit the expression of TOP2A gene,while the knockout of HBB gene had the opposite effect.Conclusion HBB gene is lowly expressed in the serum of HCC patients and is significantly negatively correlated with the expression of TOP2A gene.

Objective To compare the safety of laparoscopic pancreatoduodenectomy(LPD)and open pancreatoduodenectomy(OPD)and analyze the learning curve and safety at different stages of LPD.Methods A retrospective analysis was conducted on the clinical data of 50 LPD patients and 54 OPD patients in the Department of Hepatopancreatobiliary Surgery of Suzhou Hospital Affiliated to Nanjing Medical University from January 2020 to June 2024,and intraoperative and postoperative conditions were compared.The Cumulative Sum(CUSUM)analysis method was used to analyze the technical nodes of the LPD learning curve.Results There were no significant differences in operation time and intraoperative blood loss between the LPD group and the OPD group(P＞0.05).There was also no significant difference in the incidence rates of pancreatic fistula(grade B and C),delayed gastric emptying,postoperative bleeding,biliary fistula and intra-abdominal infection between the LPD group and the OPD group(P＞0.05).A time series plot of operation time was drawn based on the patient's operation time and surgical sequence,yielding a fitted curve.Curve analysis showed initial stage and stable stage were finished at the 17th and 24th cases.The LPD learning curve could be divided into three stages:stage Ⅰ characterized as the initial stage(cases 1 to 17),stage Ⅱ characterized as the stable stage(cases 18 to 24),and stage Ⅲ characterized as the proficient stage(cases 25 to 50).The operation time in stages Ⅱ and Ⅲ was significantly shorter than that in stage Ⅰ,and the intraoperative blood loss in stage Ⅰ was significantly higher than that in stage Ⅲ(P＜0.05).There was no significant difference in the incidence of complications among the three stages(P＞0.05).Conclusion LPD and OPD show no significant differences in indications and safety.The LPD learning curve can be divided into three stages.As the number of surgeries completed increa-ses,the operation time of physicians gradually shortens,and the incidence of complications of patients gradually decreases.

Spleen-stomach damp-heat syndrome is currently the most prevalent TCM pattern in patients with chronic atrophic gastritis (CAG), with internal damp-heat accumulation regarded as a key factor contributing to its prolonged and refractory course. This syndrome represents a critical stage in the progressive pathogenesis of CAG, characterized by a deepening pathological evolution. Modern TCM practitioners generally agree that its core pathogenesis lies in "deficiency in root and excess in superficiality, with internal damp-heat retention", and emphasize a treatment strategy that combines eliminating pathogenic factors and reinforcing the body's healthy qi through dynamic syndrome differentiation. Chinese materia medica used in treating CAG with spleen-stomach damp-heat syndrome can effectively relieve clinical symptoms, improve the internal damp-heat environment, mitigate gastric mucosal atrophy and intestinal metaplasia, and delay the inflammation-to-cancer transformation. Its mechanisms may involve eradication of Helicobacter pylori, repair of gastric mucosal injury, regulation of immune inflammatory response and other aspects, which has the advantages of multi-channel and multi-target.

Objective To investigate the relationship between interleukin-1β (IL-1β) and miR-185-5p in the process of joint injury in acute gouty arthritis (AGA). Methods The serum miR-185-5p levels of 89 AGA patients and 91 healthy volunteers were detected by real-time quantitative PCR. The correlation between miR-185-5p expression level and VAS score or IL-1β expression level was evaluated by Pearson correlation coefficient method. Receiver operating characteristic (ROC) curve was used to evaluate the diagnostic value of miR-185-5p in AGA. THP-1 cells were induced by sodium urate (MSU) to construct an in vitro acute gouty inflammatory cell model. After the expression level of miR-185-5p in THP-1 cells was upregulated or downregulated by transfection of miR-185-5p mimics or inhibitors in vitro, inflammatory cytokines of THP-1 cells, such as IL-1β, IL-8 and tumor necrosis factor α (TNF-α), were detected by ELISA. The luciferase reporter gene assay was used to determine the interaction between miR-185-5p and the 3'-UTR of IL-1β. Results Compared with the healthy control group, the expression level of serum miR-185-5p in AGA patients was significantly reduced. The level of serum miR-185-5p was negatively correlated with VAS score and IL-1β expression level. The area under the curve (AUC) was 0.905, the sensitivity was 80.17% and the specificity was 83.52%. Down-regulation of miR-185-5p significantly promoted the expression of IL-1β, IL-8 and tumor necrosis factor (TNF-α), while overexpression of miR-185-5p showed the opposite results. Luciferase reporter gene assay showed that IL-1β was the target gene of miR-185-5p, and miR-185-5p negatively regulated the expression of IL-1β. Conclusion miR-185-5p alleviates the inflammatory response in AGA by inhibiting IL-1β.

Objective:To investigate long-term auditory changes and characteristics of Alport syndrome（AS） patients with different degrees of renal injury. Methods:Retrospectively analyzing clinical data of patients diagnosed AS from January 2007 to September 2022, including renal pathology, genetic detection and hearing examination. A long-term follow-up focusing on hearing and renal function was conducted. Results:This study included 70 AS patients, of which 33（25 males, 8 females, aged 3.4-27.8 years） were followed up, resulting in a loss rate of 52.9%.The follow-up period ranged from 1.1to 15.8 years, with 16 patients followed-up for over 10 years. During the follow-up, 10 patients presenting with hearing abnormalities at the time of diagnosis of AS had progressive hearing loss, and 3 patients with new hearing abnormalities were followed up, which appeared at 5-6 years of disease course. All of which were sensorineural deafness. While only 3 patients with hearing abnormalities among 13 patients received hearing aid intervention. Of these patients,7 developed end-stage renal disease（ESRD）, predominantly males （6/7）. The rate of long-term hearing loss was significantly different between ESRD group and non-ESRD group（P=0.013）. There was no correlation between the progression of renal disease and long-term hearing level（P>0.05）. kidney biopsies from 28 patients revealed varying degrees of podocyte lesion and uneven thickness of basement membrane. The severity of podocyte lesion was correlated with the rate of long-term hearing loss（P=0.048）, and there was no correlation with the severity of hearing loss（P>0.05）. Among 11 cases, theCOL4A5mutationwas most common （8 out of 11）, but there was no significant correlation between the mutation type and hearing phenotype（P>0.05）. Conclusion:AS patients exhibit progressive hearing loss with significant heterogeneity over the long-term.. THearing loss is more likely to occur 5-6 years into the disease course. Hearing abnormalities are closely related to renal disease status, kidney tissue pathology, and gene mutations, emphasizing the need for vigilant long-term hearing follow-up and early intervention.

Objectives:This study aimed to analyze the clinical and molecular characteristics of carbapenem-resistant Enterobacteriaceae (CRE) bloodstream infection (BSI) in patients with hematological diseases and to explore prognostic risk factors.Methods:This retrospective study included patients with hematologic diseases with CRE BSI at the Institute of Hematology and Blood Diseases Hospital from January 2015 to December 2022. The clinical features, carbapenemase test results, antimicrobial treatments, and outcomes were analyzed.Results:A total of 120 patients developed CRE BSI. Escherichia coli (58/120, 48.3%) was the most prevalent Enterobacteriaceae, followed by Klebsiella pneumoniae (52/120, 43.3%). A total of 93 CRE strains were tested for carbapenemase, of which 75 strains produced carbapenemase (metalloenzyme: 51 strains; serine enzyme: 24 strains). The 30-day mortality rate after BSI was 24.2% (29/120). Univariate analysis revealed significantly lower mortality in patients treated with the ceftazidime-avibactam-containing regimen than in those treated with other antibiotics (7.8% vs 36.2%, P<0.001). Moreover, initiating active therapy within 24 h of BSI onset significantly reduced mortality (15.0% vs 33.3%, P=0.019). The proportion of patients with CRE colonization receiving active therapy within 12 and 24 h was significantly higher compared with patients without colonization (12 h: 14.5% vs 34.1%, P=0.012; 24 h: 40.8% vs 65.9%, P=0.008). Multivariate analysis revealed that septic shock ( HR=24.436, 95% CI 4.148 - 143.966, P<0.001) and pulmonary infection ( HR=9.346, 95% CI 2.718-32.140, P<0.001) were independent risk factors for death within 30 days. Appropriate therapy was initiated within 24 h ( HR=0.225, 95% CI 0.059 - 0.851, P=0.028), and treatment with the ceftazidime-avibactam-containing regimen ( HR=0.082, 95% CI 0.018-0.362, P=0.001) significantly reduced mortality. Conclusion:The prognosis of CRE BSI in patients with hematological diseases is poor. Timely, appropriate therapy and receipt of a ceftazidime-avibactam-containing regimen can improve survival and prognosis.

This paper summarized Professor ZHUANG Lixing's clinical experience in differentiating and treating levodopa-induced dyskinesia （LID） in Parkinson's disease. It is believed that the fundamental pathogenesis of LID lies in the disharmony or malnourishment of tendons and vessels. Based on the clinical manifestations， peak-dose LID is differentiated into two syndromes： syndrome of hyperactive liver yang causing wind and syndrome of deficiency of both liver and kidney. For the syndrome of hyperactive liver yang causing wind， the treatment focuses on calming the liver to stop the wind， and relaxing the tendons to stop tremors. The main prescription used is Zhengan Xifeng Decoction （镇肝熄风汤） with the addition of Shijueming （石决明） and Zhenzhumu （珍珠母）. For the syndrome of deficiency of both liver and kidney， the treatment focuses on nourishing the liver and kidneys， and replenishing yin to stop the wind. The main prescription used is Dabuyin Pills （大补阴丸） with modification. LID in the acoustic phase is differentiated into syndrome of phlegm-damp blocking middle jiao and syndrome of deficiency of both qi and yin. For the syndrome of phlegm-damp blocking middle jiao， the treatment focuses on dissipating phlegm and eliminating dampness， and nurturing tendons and vessels. Wendan Decoction （温胆汤） or Erchen Decoction （二陈汤） with modification is used. For the syndrome of deficiency of both qi and yin， the treatment focuses on replenishing qi and nourishing blood， and nurturing tendons and vessels. The main prescriptions used are Buzhong Yiqi Decoction （补中益气汤） or Bazhen Decoction （八珍汤） or Shenling Baizhu Powder （参苓白术散） with modification. Biphasic LID is differentiated as the Shaoyang pivot disadvantageousness， and the treatment focuses on harmonizing Shaoyang and regulating the pivot. The main prescription used is Xiaochaihu Decoction （小柴胡汤） with modification.
