To report diagnosis and treatment of a patient with rectal cancer and synchronous liver metastases, accompanied by severe coronary artery stenosis and cardiac insufficiency, and to provide a reference for clinical decision-making in such cases through introducing the treatment contradiction, the choice of systemic treatment plan and the timing of operation, and the final outcome. After definitive diagnosis, the patient received systemic therapy with cetuximab＋irinotecan＋oxaliplatin＋raltitrexed, and along with oral medication to improve cardiac function, followed by elective coronary revascularization. After revascularization, the cardiac function of patient was fully improved. And the tumor lesion was effectively controlled after antitumor therapy. Once the cardiac condition of patient stabilized, two-stage surgical resection of the primary rectal cancer and liver metastases was performed, ultimately achieving tumor-free status, and discharged.

AIM: To analyze the value of blue-on-yellow perimetry(B/Y)combined with macular ganglion cells inner plexiform layer(GCIPL)detection in the early diagnosis of open angle glaucoma.METHODS: A prospective case-control study was conducted to collect 100 patients(174 eyes)from May 2023 to May 2024 in Eye Hospital of Wenzhou Medical University as the case group, and 20 healthy volunteers(40 eyes)as the control group. The case group was divided into high intraocular pressure group, suspected glaucoma group, and early glaucoma group based on the examination results. All study subjects underwent comprehensive ophthalmic examination, white-on-white perimetry(W/W)and B/Y examination, and swept source optical coherence tomography(SS-OCT)was used to scan the optic disc and macula to obtain relevant parameters. The value of B/Y combined with macular GCIPL in the diagnosis of open angle glaucoma was analyzed.RESULTS: In the case group, 30 cases(52 eyes)were diagnosed with early primary open angle glaucoma, 46 cases(82 eyes)were suspected of open angle glaucoma, and 24 cases(40 eyes)were diagnosed with high intraocular pressure. The W/W mean defect(MD)and B/Y-MD values in the early glaucoma group were lower than those in the control group, high intraocular pressure group, and suspected glaucoma group. The W/W pattern standard deviation(PSD)and B/Y-PSD values were higher than those in the control group, high intraocular pressure group, and suspected glaucoma group(all P<0.05). The W/W-MD and B/Y-MD values in the suspected glaucoma group were lower than those in the control group and the high intraocular pressure group(all P<0.05). The B/Y-MD values in the high intraocular pressure group were lower than those in the control group(P<0.05). The parameters of GCIPL in the macular area of the early glaucoma group were lower than those of the control group, high intraocular pressure group, and suspected glaucoma group(all P<0.05). The minimum GCIPL in the macular area of the suspected glaucoma group, as well as the upper and lower temporal areas, were lower than those of the control group and the high intraocular pressure group(all P<0.05). The average, upper, lower, temporal, 5:00, 6:00, and 12:00 positions of the retinal nerve fiber layer(RNFL)parameters around the optic disc in the early glaucoma group were lower than those in the control group, high intraocular pressure group, and suspected glaucoma group(all P<0.05). The average and upper RNFL parameters in the suspected glaucoma group were lower than those in the control group and high intraocular pressure group. The rim area of the optic nerve head(ONH)parameters in the early glaucoma group was smaller than that in the control group, high intraocular pressure group, and suspected glaucoma group, while the horizontal and vertical cup-to-disc ratio was higher than those in the control group, high intraocular pressure group, and suspected glaucoma group; the rim area of the suspected glaucoma group was smaller than that of the control group and high intraocular pressure group, and the horizontal and vertical cup-to-disc ratio were higher than those of the control group and high intraocular pressure group(all P<0.05). Receiver operating characteristic(ROC)curve was drawn, and the results showed that visual field parameters, macular GCIPL parameters, and RNFL parameters had certain diagnosibility for early open angle glaucoma and suspected glaucoma. Decision curve was drawn, and the results showed that when the threshold was between 0 and 1.0, the net return rate of diagnosing early open angle glaucoma with the combination of B/Y and macular GCIPL parameters was higher than the individual diagnostic efficacy of each indicator.CONCLUSION: The combination of B/Y and macular GCIPL detection can be an important means for the early diagnosis of glaucoma.

AIM: To analyze the changes of retinal structure and function before and after panretinal photocoagulation(PRP)in patients with proliferative diabetic retinopathy(PDR).METHODS: Prospective study. Totally 98 cases(98 eyes)of PDR patients who underwent PRP in Eye Hospital of Wenzhou Medical University from January 2022 to May 2023 were included. Optical coherence tomography angiography(OCTA)was used to detect central retinal thickness(CRT), central macular thickness(CMT), subfoveal choroidal thickness(SFCT), foveal avascular zone(FAZ), deep vascular complex(DVC)blood flow density, superficial vascular complex(SVC)blood flow density before and at 1 wk, 1 and 3 mo after PRP. During the follow-up, 1 eye underwent vitrectomy, 2 eyes were lost to follow-up, and finally 95 eyes completed 1 a follow-up, with a loss rate of 3%. According to the visual prognosis at 1 a after treatment, the patients were divided into two groups: 73 eyes in good prognosis group and 22 eyes in poor prognosis group(including 9 eyes of visual disability and 13 eyes of visual regression). The changes in retinal structure and function before and after PRP treatment were compared between the two groups of patients, and the receiver operating characteristic(ROC)curve and decision curve were used to analyze the predictive value of retinal structure and function for PDR treatment.RESULTS: There were statistical significant differences in PDR staging, CRT, CMT, SFCT, DVC blood flow density, and SVC blood flow density between the two groups of patients before treatment(all P<0.05). At 1 wk, 1 and 3 mo after treatment, the FAZ area of both groups decreased compared to before treatment, while the blood flow density of DVC and SVC increased compared to before treatment(both P<0.05). However, there was no significant difference in the blood flow density of FAZ, DVC, and SVC between the two groups at 1 wk, 1 and 3 mo after treatment(all P>0.05). The CRT, CMT and SFCT of the two groups at 1 wk after treatment were higher than those before treatment(all P<0.05), but there were no significant differences between the two groups(all P>0.05). The CRT, CMT and SFCT at 1 and 3 mo after treatment were lower than those at 1 wk after treatment and before treatment in both groups. The CRT, CMT and SFCT in the poor prognosis group at 3 mo after treatment were higher than those at 1 mo after treatment, and were higher than those in the good prognosis group(all P<0.05). ROC analysis showed that, at 3 mo after laser treatment in PDR patients, the area under the curve of the CRT, CMT, and SFCT alone or in combination after treatment for 1 a was 0.788, 0.781, 0.783, and 0.902, respectively, and the combined prediction value was better(P<0.05). Decision curve analysis showed that the combined detection of CRT, CMT, and SFCT in PDR patients at 3 mo after treatment can improve the predictive value of visual prognosis.CONCLUSION: The optimal time for retinal structure and function recovery in PDR patients after PRP treatment is between 1 wk and 1 mo. OCTA measurement of CRT, CMT, and SFCT at 3 mo after treatment can predict the visual prognosis during the 1 a treatment period.

Objective To explore the potential causal relationship between occupational pneumoconiosis (hereinafter referred to as "pneumoconiosis") and five mental disorders (depression, bipolar disorder, schizophrenia, insomnia and anxiety) using the two-sample Mendelian randomization (MR) method. Methods Single nucleotide polymorphisms (SNPs) loci associated with pneumoconiosis and five mental disorders were screened from Genome-Wide Association Studies. Inverse variance weighting (IVW), weighted median (WM) and MR-Egger regression methods were used to evaluate the significance of the causal relationship between pneumoconiosis and five mental disorders. Sensitivity analysis was used to evaluate the accuracy and reliability of the research results. Results After matching data of pneumoconiosis and the five mental disorders, 16 SNPs were ultimately included as instrumental variables in this study. The result of MR analysis revealed a positive causal relationship between pneumoconiosis and both depression [IVW: odds ratio (OR) and 95% confidence interval (CI) was 1.017 (1.000-1.035), P<0.05] and bipolar disorder [IVW: OR(95%CI)was 1.046(1.009-1.083), P<0.05; WM: OR (95%CI) was 1.055(1.007-1.105), P<0.05]. Result of sensitivity analysis indicated there was no heterogeneity and horizontal pleiotropy in the above results. There was no causal association observed between pneumoconiosis and schizophrenia, insomnia, or anxiety disorders (all P>0.05). Conclusion This study provides genetic evidence supporting a positive causal relationship between pneumoconiosis and both depression and bipolar disorder.

Effective axon regeneration is essential for the successful restoration of nerve functions in patients suffering from axon injury-associated neurological diseases. Certain self-regeneration occurs in injured peripheral axonal branches of dorsal root ganglion (DRG) neurons but does not occur in their central axonal branches. By performing rat sciatic nerve or dorsal root axotomy, we determined the expression of the dysbindin domain containing 2 (DBNDD2) in the DRGs after the regenerative peripheral axon injury or the non-regenerative central axon injury, respectively, and found that DBNDD2 is down-regulated in the DRGs after peripheral axon injury but up-regulated after central axon injury. Furthermore, we found that DBNDD2 expression differs in neonatal and adult rat DRGs and is gradually increased during development. Functional analysis through DBNDD2 knockdown revealed that silencing DBNDD2 promotes the outgrowth of neurites in both neonatal and adult rat DRG neurons and stimulates robust axon regeneration in adult rats after sciatic nerve crush injury. Bioinformatic analysis data showed that transcription factor estrogen receptor 1 (ESR1) interacts with DBNDD2, exhibits a similar expression trend as DBNDD2 after axon injury, and may targets DBDNN2. These studies indicate that reduced level of DBNDD2 after peripheral axon injury and low abundance of DBNDD2 in neonates contribute to axon regeneration and thus suggest the manipulation of DBNDD2 expression as a promising therapeutic approach for improving recovery after axon damage.

Objective : To explore the mechanism of proliferation of gastric cancer cells induced byHelicobacter pylori(Hp) from the perspective of the mitochondrial unfolded protein response(UPRMT). Methods : C57BL6/J mice, human gastric cancer cells AGS and SGC-7901 cells were infected with Hp, mitochondrial proteins were extracted, and the expressions of UPRMT, including activation of transcription factor 5(ATF5), heat shock protein 60(mtHSP60), heat shock protein 70(mtHSP70) and mitochondrial protease(ClpP), were detected by Western blot. Immunohistochemistry was used to locate the expression sites of 4 proteins in mouse gastric tissue. AGS and SGC-7901 cells were infected with Hp, and cell proliferation was detected by RTCA and CCK-8. Finally, the expression of four indexes in gastric cancer tissues was analyzed by TCGA samples in the UALCAN database. Results : Hp infection could significantly promote the expression of ATF5, mtHSP60, mtHSP70 and ClpP in the mitochondria of gastric epithelial cells of C57BL6/J mice, AGS and SGC-7901 cells, and promote the proliferation of gastric cancer cells. When compared to normal gastric tissues in TCGA samples, ATF5, mtHSP60, mtHSP70, and ClpP were highly expressed in gastric cancer tissues, with statistically significant difference(allP<0.01). Conclusion Hp infection can induce UPRMTin gastric epithelial cells and gastric cancer cells, which in turn promotes cell proliferation.

Background and purpose:Approximately 30%of patients with metastatic colorectal cancer(CRC)develops pulmonary metastasis,yet less than 10%are eligible for surgical resection.Radiofrequency ablation(RFA)serves as an alternative therapy for non-surgical candidates,but the relationship between its efficacy and tumor diameter remains controversial.This study aimed to investigate the impact of tumor size on survival outcomes and local progression risk in CRC patients with pulmonary metastasis after RFA,and to validate the clinical utility of a 3 cm threshold for prognosis.Methods:This retrospective study included CRC patients with pulmonary metastasis who underwent RFA at Fudan University Shanghai Cancer Center between January 2016 and December 2024.Patients were stratified into two groups based on maximum lesion diameter:≤3 cm(Small group)and 3-5 cm(Large group).Patient inclusion criteria:⑴ pathologically confirmed lung metastases originating from CRC,with metastases limited to the lungs or extra-pulmonary metastatic lesions having been radically treated;⑵ maximum lesion diameter<5 cm;⑶complete clinical data available;⑷ complete imaging data available,including computed tomography(CT)images during ablation and contrast-enhanced CT images during postoperative follow-up;⑸ follow-up time of at least＞6 months after RFA;⑹ technical complete ablation;⑺ fewer than 3 pulmonary metastatic lesions.Exclusion criteria:⑴ target lesions previously treated with local therapies such as RFA or radiotherapy;⑵ patients unable to tolerate RFA;⑶ patients with follow-up time＜6 months after RFA.Three senior interventional physicians performed percutaneous RFA under guidance of a 64-slice spiral CT scanner.Chest contrast-enhanced CT scans obtained 1 month after RFA were used as the baseline,followed by contrast-enhanced CT scans every 3 months for 1 year,then every 6 months for subsequent follow-up.This study was approved by the medical ethics committee of Fudan University Shanghai Cancer Center(ethical approval number:2108241-11).Primary endpoints included overall survival(OS),progression-free survival(PFS),and local tumor progression(LTP).Kaplan-Meier analysis and multivariate COX regression were employed to evaluate the independent prognostic value of tumor size.Results:A total of 134 patients who met the inclusion criteria were ultimately enrolled,including 77 in the Small group and 57 in the Large group.With a median follow-up of 35 months,the≤3 cm group demonstrated superior 1-,3-,and 5-year OS rates(100.0%,95.1%,74.2%)compared to the 3-5 cm group(94.7%,36.8%,27.0%,P＜0.0001),and the≤3 cm group demonstrated superior 1-,3-,and 5-year PFS rates(90.9%,34.4%,23.3%)compared to the 3-5 cm group(13.8%,0.0%,0.0%,P＜0.000 1).The≤3 cm group also exhibited significantly lower 1-,3-,and 5-year LTP rates(0.0%,19.7%,33.6%)compared to the 3-5 cm group(46.0%,75.5%,75.5%,P＜0.000 1).Multivariable analysis identified tumor diameter＞3 cm as an independent predictor of worse OS[hazard ratio(HR)=6.49,95%CI:3.18-13.24,P＜0.001],while elevated preoperative carcinoembryonic antigen(CEA)(≥5 ng/mL)correlated with shorter OS(HR=1.82,P=0.033).Conclusion:CRC patients with pulmonary metastasis and tumor diameters of 3-5 cm exhibited significantly inferior survival outcomes after RFA compared to the≤3 cm group.A tumor diameter of 3 cm can serve as a critical threshold for selecting RFA indications,and combining preoperative CEA levels can optimize patient stratification.

Objective To discusse the application effects of the informatization of the review center and the homogeneity of pharmacists on the rationality of emergency department prescriptions.Methods Based on the system rules of the rational drug use management system and manually set custom rules,the changes in pharmacist's review quality,efficiency homogeneity,and prescription rationality were compared before(February 2023 to July 2023)and after(August 2023 to January 2024)the construction of the review center,according to the informatization and process standardization management.Results After the establishment of the review center,analysis of variance showed that the approval rate of pharmacist's review significantly increased compared to before the establishment of the review center(P＜0.05),while the average time consumption increased significantly(P＜0.01).The average review time,average approval time,and average review return time have been extended from(4.50±0.58),(4.50±0.58),and(4.75±0.96)s to(11.67±1.03),(8.50±0.55)and(13.17±0.98)s,respectively.The trend chi-square test showed that the irrationality rate of emergency department prescriptions decreased monthly from 6.27％in August 2023 to 0.93％in January 2024(P＜0.01).Correlation analysis between the number of intervention system rules since the establishment of the review center and the irrationality rate of emergency department prescriptions revealed a significant correlation(P=0.004 4).Conclusions By utilizing the platform of the review center,establishing dedicated review pharmacists and an information pharmacist team,and implementing informatization and standardized management processes,it can contribute to improving the quality and efficiency of prescription review,increasing the qualification rate of prescriptions,ensuring rational drug use,and enhancing the management level and medical quality of hospitals.

Objective To assess the clinical value of a novel surgical technique—Tubeless subxiphoid uniportal video-assisted thoracoscopic surgery with percutaneous suspension technique via balance-shaped sternal elevation device in the resection of anterior mediastinal masses. Methods Patients who underwent tubeless subxiphoid uniportal video-assisted thoracoscopic surgery via balance-shaped sternal elevation device in anterior mediastinal masses process at the Department of Thoracic Surgery, West China Hospital, Sichuan University from March to April 2025 were included, and their clinical data were analyzed. Results A total of 4 patients were included, with 2 males and 2 females, aged 58-75 years. The diameter of the tumor was 2.5-3.0 cm. The operation time was 60.0-150.0 min, intraoperative blood loss was 5-10 mL, pain score on the 3rd day after surgery was 0 points, and postoperative hospital stay was 2-3 days. All patients achieved complete resection of the masses and thymus without perioperative complications. Conclusion The tubeless subxiphoid uniportal video-assisted thoracoscopic surgery with percutaneous suspension technique via balance-shaped sternal elevation device technique optimizes surgical visualization and instrument maneuverability while avoiding complications related to conventional anesthesia and tubing, thereby markedly enhancing the minimally invasive profile of anterior mediastinal masses resections. In addition to maintaining procedural safety, this approach effectively reduces postoperative pain and accelerates patient recovery, highlighting its potential for widespread clinical adoption.
