BACKGROUND: The available evidence regarding the benefits of percutaneous coronary intervention (PCI) on patients receiving dialysis with coronary artery disease (CAD) is limited and inconsistent. This study aimed to evaluate the association between PCI and clinical outcomes as compared with medical therapy alone in patients undergoing dialysis with CAD in China. METHODS: This multicenter, retrospective study was conducted in 30 tertiary medical centers across 12 provinces in China from January 2015 to June 2021 to include patients on dialysis with CAD. The primary outcome was major adverse cardiovascular events (MACE), defined as a composite of cardiovascular death, non-fatal myocardial infarction, and non-fatal stroke. Secondary outcomes included all-cause death, the individual components of MACE, and Bleeding Academic Research Consortium criteria types 2, 3, or 5 bleeding. Multivariable Cox proportional hazard models were used to assess the association between PCI and outcomes. Inverse probability of treatment weighting (IPTW) and propensity score matching (PSM) were performed to account for potential between-group differences. RESULTS: Of the 1146 patients on dialysis with significant CAD, 821 (71.6%) underwent PCI. After a median follow-up of 23.0 months, PCI was associated with a 43.0% significantly lower risk for MACE (33.9% [ n  = 278] vs . 43.7% [ n  = 142]; adjusted hazards ratio 0.57, 95% confidence interval 0.45-0.71), along with a slightly increased risk for bleeding outcomes that did not reach statistical significance (11.1% vs . 8.3%; adjusted hazards ratio 1.31, 95% confidence interval, 0.82-2.11). Furthermore, PCI was associated with a significant reduction in all-cause and cardiovascular mortalities. Subgroup analysis did not modify the association of PCI with patient outcomes. These primary findings were consistent across IPTW, PSM, and competing risk analyses. CONCLUSION This study indicated that PCI in patients on dialysis with CAD was significantly associated with lower MACE and mortality when comparing with those with medical therapy alone, albeit with a slightly increased risk for bleeding events that did not reach statistical significance.

Amoenucles A-F (1-6), six previously undescribed nucleoside derivatives, and two known analogs (7 and 8) were isolated from the culture of Aspergillus amoenus TJ507. Their structures were elucidated through spectroscopic analysis, single-crystal X-ray crystallography, and chemical reactions. Notably, 3 and 4 represent the first reported instances of nucleosides with an attached pyrrole moiety. Of particular significance, the absolute configuration of the sugar moiety of 1-4 was determined using nuclear magnetic resonance (NMR), electric circular dichroism (ECD) calculations, and a hydrolysis reaction, presenting a potentially valuable method for confirming nucleoside structures. Furthermore, 1, 2, and 5-8 exhibited potential tumor necrosis factor α (TNF-α) inhibitory activities, which may provide a novel chemical template for the development of agents targeting autoimmune and inflammatory diseases.

OBJECTIVE To investigate the potential mechanism of the effect of ginkgo flavone aglycone （GA） against doxorubicin （DOX）-induced cardiotoxicity. METHODS The male ICR mice were randomized into control group （CON group）， model group （DOX group） and GA+DOX group （GDOX group）， with 12 mice in each group. The DOX group was injected with DOX solution at a dose of 3 mg/kg via tail vein every other day， and the GDOX group was given GA suspension intragastrically at a dose of 100 mg/kg every day+DOX solution at a dose of 3 mg/kg via tail vein every other day， for 15 consecutive days. After the end of administration， the serum levels of aspartate aminotransferase（AST）， creatine kinase（CK）， creatine kinase isoenzyme（CK- MB） and lactate dehydrogenase（LDH） in mice were detected in each group. Based on the metabolomics method， UHPLC-Q- Exactive Orbitrap HRMS method was used； based on principal component analysis （PCA） and orthogonal partial least squares- discriminant analysis （OPLS-DA）， the differentially expressed metabolites （DEMs） were screened using the criteria of variable importance in the projection≥1， fold change of peak area＞1 and P＜0.05； biological analysis was conducted based on databases such as HMDB and PubChem. RESULTS Compared with CON group， serum levels of AST， CK， CK-MB and LDH were increased significantly in DOX group （P＜0.05）； compared with DOX group， the serum levels of the above indicators （except for CK-MB） were decreased significantly in GDOX group （P＜0.05）. PCA and OPLS-DA showed that myocardial tissue samples of CON group， DOX group and GDOX group were isolated completely. After database matching， 37 common DEMs were identified， among which 17 DEMs were significantly up-regulated in the DOX group and significantly down- regulated in the GDOX group， and 8 DEMs were significantly down-regulated in the DOX group and significantly up-regulated in the GDOX group； pathway enrichment involved the biosynthesis of unsaturated fatty acids， arachidonic acid metabolism， linoleic acid metabolism， taurine and hypotaurine metabolism； the key metabolites in the above pathways included docosahexaenoic acid， arachidonic acid， phosphatidylcholine （16∶0/18∶3） and taurine. CONCLUSIONS GA may regulate the biosynthesis of unsaturated fatty acids， arachidonic acid metabolism and other metabolic pathways by acting on the core metabolites such as docosahexaenoic acid and arachidonic acid， thus alleviating the cardiotoxic effects of DOX.

OBJECTIVE To investigate the mechanism by which Ginkgo flavone aglycone （GA） reduces the cardiotoxicity of doxorubicin （DOX） based on transcriptomics and proteomics. METHODS Thirty-six mice were randomly assigned to control group （CON group， tail vein injection of equal volume of physiological saline every other day+daily intragastric administration of an equal volume of physiological saline）， DOX group （tail vein injection of 3 mg/kg DOX every other day）， and GDOX group （daily intragastric administration of 100 mg/kg GA+tail vein injection of 3 mg/kg DOX every other day）， with 12 mice in each group. The administration of drugs/physiological saline was continued for 15 days. Mouse heart tissues were collected for RNA-Seq transcriptomic sequencing and 4D-Label-free quantitative proteomic analysis to screen differentially expressed genes and proteins， which were then subjected to Kyoto encyclopedia of genes and genomes （KEGG） enrichment analysis. The expression levels of Apelin peptide （Apelin）， phosphatidylinositol 3-kinase （PI3K）， and protein kinase B （Akt） mRNA and protein in mouse heart tissues， as well as the phosphorylation levels of PI3K and Akt proteins， were verified. H9c2 cardiomyocytes were divided into control group （CON group）， DOX group （2 μmol/L）， and GDOX group （2 μg/mL GA+2 μmol/L DOX） to determine cell viability and the levels of key glycolytic substances in the cells. RESULTS Six common pathways were identified from transcriptomics and proteomics， including the Apelin signaling pathway， the PI3K-Akt signaling pathway， and insulin resistance. Among them， the Apelin and PI3K-Akt signaling pathways were the most enriched in terms of gene numbers. Target validation experiments showed that compared to the CON group， the relative expression of Apelin， PI3K and Akt mRNA and protein levels， as well as the phosphorylation levels of PI3K and Akt proteins， were significantly decreased in the DOX group （P＜0.05 or P＜0.01）. The relative expression of Apelin， PI3K and Akt mRNA and the phosphorylation levels of PI3K and Akt proteins were significantly increased in the GDOX group as compared with the DOX group （P＜0.05 or P＜0.01）. Cellular experiments indicated that compared to the CON group， cell viability in the DOX group was significantly decreased （P＜0.05）， the relative uptake of glucose and the relative production of pyruvate and lactate were significantly increased （P＜0.05）， and the relative production of ATP was significantly reduced （P＜0.05）. Compared to the DOX group， cell viability in the GDOX group was significantly increased （P＜ 0.05）， and the relative production of pyruvate and lactate was significantly reduced （P＜0.05）. CONCLUSIONS GA may alleviate DOX-induced cardiotoxicity by upregulating the mRNA and protein expression of Apelin， PI3K， and Akt in heart tissues， and regulating glycolytic processes.

Objective To analyze the clinical features and surgical treatment strategies of T4a thyroid cancer.Methods We retrospectively analyzed patients with thyroid cancer treated in the Department of Head and Neck Surgery of Sichuan Cancer Hospital from January 2004 to May 2021.A total of 303 cases were included and statistically analyzed for pathological type,invaded organs,surgical approach,survival time,and overall survival rate.The postoperative survival curves of the patients were analyzed using the Kaplan Meier method.Results Of the 303 patients enrolled,53 patients were lost to follow-up,and the 1-year,3-year and 5-year overall survival rates were 98.4％(246/250),97.0％(224/231)and 90.2％(92/102),respectively.Of the 94 patients with recurrent laryngeal nerve invasion only,13 were lost to follow-up,and the 1-year,3-year and 5-year overall survival rates were 100％(81/81),98.7％(77/78)and 97.4％(38/39),respectively.There were 151 patients with invasion of recurrent laryngeal nerve and tracheal/laryngeal/esophageal nerve,31 of them were lost to follow-up,and the 1-year,3-year and 5-year overall survival rates were 96.7％(116/120),95.3％(101/106)and 82.2％(37/45),respectively.According to the survival curve analysis,the group with recurrent laryngeal nerve invasion only had an advantage in overall survival time over the group with recurrent laryngeal nerve and tracheal/laryngeal/esophageal invasion.Conclusion Surgical resection is supposed to be preferred for T4a thyroid cancer if there is a chance of surgery.A reasonable surgical strategy,radical surgery while preserving the vital tissues and organs,and one-stage repair and reconstruction can bring patients a better quality of life and prognosis.

Objective:To evaluate safety and efficacy of B-type suture method ileostomy.Methods:Clinical data from 204 patients undergoing laparoscopic low anterior resection combined with protective ileostomy was analysed. Patients were divided into B-type suture ileostomy group ( n=67) and traditional ileostomy group ( n=137). Results:compared with traditional ileostomy group, B-type suture ileostomy group showed statistically significant differences in total operation time [(164±26) min vs. (172±24) min, t=2.229, P=0.027], ileostomy time [(12.7±2.3) min vs. (14.8±2.2) min, t=-6.565, P<0.001], blood loss [(57±20) ml vs. (69±31) ml, t=-2.797, P=0.006], postoperative hospital stay [(10.2±1.9) d vs. (11.8±2.3) d, t=-4.851, P<0.001], specimen incision infection rate (0 vs. 5.1%, P=0.047), postoperative body pain [82 (79-84) vs. 78 (76-80), Z=-5.805, P<0.001], and ileostomy incorporation time [(46±11) min vs. (51±12) min, t=-2.540, P=0.012]. Conclusion:B-type suture ileostomy for prophylactic ileostomy in laparoscopic low anterior resection for rectal cancer is safe and feasible.

Objective:To analyze the normal expression levels of different lung cancer tumor markers(TM)in the cerebrospinal fluid and to explore the influence of serum TM levels and brain parenchymal metastasis,to more accurately determine whether the cerebrospinal fluid TM levels of patients with suspected meningeal metastasis is elevated.Methods:The clinical data of 80 patients diagnosed with non-lepto-meningeal metastasis at Tianjin Medical University Cancer Hospital between January 2015 and February 2024 were collected,including 16 patients without lung cancer and 64 patients with lung cancer.Normal TM levels in the cerebrospinal fluid of patients without lung cancer and the difference in TM levels between the cerebrospinal fluid and serum samples were analyzed.The correlation between serum and cerebrospinal fluid TM levels was also analyzed.We then compared the differences in TM levels in the cerebrospinal fluid between groups with brain parenchymal metastasis and without brain parenchymal metastasis.Results:Normal levels of TPSA,CA19-9,CEA,Cyfra21-1,and SCC in the cerebrospinal fluid were lower than those in the serum(P<0.05);however,the levels of ProGRP and NSE in the cerebrospinal fluid were higher than those in the serum(P<0.05).The levels of TPSA,SCC,ProGRP,NSE,CEA,CA19-9,and Cyfra21-1 in the cerebrospinal fluid did not correlate with those in the serum(all P>0.05).The cerebrospinal fluid levels of TPSA,SCC,ProGRP,and CA19-9 were not significantly increased in patients with brain parenchymal metastasis compared to those in patients without brain parenchymal metastasis(P>0.05).Al-though CEA and Cyfra21-1 levels increased(P<0.05),their median values increased by less than 2 times and were all within the reference range;whereas,the level of NSE in the group with brain parenchymal metastasis was lower than that in the control group.Conclusions:The basal levels of ProGRP and NSE in normal cerebrospinal fluid were significantly higher than those in the serum;whereas,the expression levels of other TM in the cerebrospinal fluid were significantly lower than those in the serum.Whether the levels of TM in the serum were elevated and whether brain parenchymal metastasis was present,did not have a clinically significant impact on the TM levels in the cerebrospinal fluid.

Objective:To summarize the clinical value of fetoscopy in the prenatal diagnosis and treatment of amniotic band syndrome (ABS).Methods:A retrospective analysis was conducted on the clinical data of seven ABS fetuses who underwent prenatal fetoscopic intervention at the Third Affiliated Hospital of Zhengzhou University from December 2020 to August 2023. Literatures related to fetoscopic treatment of ABS were searched in databases including China National Knowledge Infrastructure, Wanfang Data, and PubMed. Clinical data were extracted and the characteristics and intervention effects of fetoscopic surgery in the treatment of ABS were summarized.Results:(1) Preoperative evaluation: the gestational age at diagnosis for the seven ABS fetuses was (19.8±4.4) weeks, and the gestational age at fetoscopic intervention was (22.2±2.8) weeks. The indications for fetoscopic intervention included umbilical cord involvement (3 cases), limb amniotic band with circular constriction (2 cases), and unclear visualization of digits (3 cases). (2) Pregnancy outcomes: among the seven ABS fetuses, four cases underwent selective termination of pregnancy due to severe intrauterine limb amputation, and three cases underwent fetoscopic lysis of amniotic bands. Among the latter three cases, one case experienced intrauterine fetal death (IUFD) two weeks after the procedure, and two cases had good postoperative outcomes. (3) Literature review: a total of 40 cases, including 37 cases from 17 articles and three cases from our institution, were included in the analysis. The indications for fetoscopic surgery included limb amniotic band with circular constriction and involvement of the umbilical cord. The success rate of the surgery was 82% (33/40), and 78% (29/37) of the affected limbs retained good functionality. Premature rupture of membranes was the most common complication, with an incidence rate of 48% (16/33). The average interval from the surgery to membrane rupture was (6.1±5.1) weeks, and the average interval from the surgery to delivery was (10.5±4.1) weeks, with an average gestational age at delivery of (33.7±3.6) weeks. The pregnant women were divided into single Trocar group (27 cases) and double Trocar group (13 cases) based on the surgical approach. The success rates in single Trocar group and double Trocar group were 78% (21/27) and 12/13, respectively, and the difference was not statistically significant ( χ2=0.474, P=0.491). The gestational age of delivery in the single Trocar group and double Trocar group was (32.7±3.4) and (35.4±3.2) weeks, respectively, and the difference was statistically significant ( t=-2.185, P<0.05). There were no statistically significant differences in the success rate of the surgery, incidence of premature rupture of membranes, interval between surgery and membrane rupture, interval between surgery and delivery, and preterm delivery rate between the two groups (all P>0.05). Conclusions:Fetoscopy could be used for prenatal assessment and intrauterine treatment of ABS. Fetoscopic lysis of amniotic bands may be an effective method for treating ABS, which helps preserve limb function and prevent intrauterine limb amputation and IUFD.

Objective:To apply the best evidence for nutritional management in patients with chronic heart failure (CHF) into clinical practice and evaluate its effectiveness.Methods:Totally 80 CHF patients admitted to the Department of Cardiology at the Affiliated Hospital of Chengde Medical University from October 2022 to March 2023 and 23 nurses involved in the project were selected by convenience sampling. The 40 CHF patients admitted from October to December 2022 formed the baseline group, while those admitted from January to March 2023 constituted the evidence application group. Evidence-based nursing methods were implemented in four stages: evidence retrieval, current status review, evidence implementation, and effectiveness evaluation. The compliance rates of review indicators, nurses' knowledge of nutritional management for CHF patients, and patient outcomes related to nutrition status and readmission rates were compared before and after evidence-based practice.Results:After evidence-based practice, the compliance rates of review indicators increased from 0-60.87% to 80.00%-100.00%. Nurses' scores on nutritional management knowledge for CHF patients increased significantly from (48.48±13.09) to (91.30±4.82), with a statistically significant difference ( P<0.05). The NRS 2002 scores of CHF patients decreased from (3.05±0.50) to (2.10±0.44), MNA-HF scores increased from (18.20±2.64) to (21.24±2.94), and albumin levels increased from (37.33±4.98) g/L to (39.24±3.29) g/L, all with statistically significant differences ( P<0.05). The 3-month readmission rate for CHF patients in the evidence application group was 10.00% (4/40), significantly lower than the 27.50% (11/40) in the baseline group ( P<0.05) . Conclusions:Evidence-based nursing practice for nutritional management in CHF patients can enhance nurses' knowledge, improve patients' nutritional status, reduce readmission rates, and improve the quality of nursing care.

Objective To compare the difference in binocular visual function after implantation of different types of intraocular lenses(IOL).Methods A total of 63 patients(126 eyes)with age-related cataract who underwent phacoe-mulsification combined with IOL implantation in Yantai Affiliated Hospital of Binzhou Medical University from October 2021 to June 2023 were collected.Among them,22 patients(44 eyes)were implanted with monofocal IOL in both eyes(mono-focal group),21 patients(42 eyes)were implanted with monofocal and multifocal IOL in both eyes,respectively(mixed group),and 20 patients(40 eyes)were implanted with multifocal IOL in both eyes(multifocal group).Another 22 patients(44 eyes)with physiological presbyopia were selected from the medical examination center of the same hospital during the same period as the control group.Uncorrected distance visual acuity(UDVA),uncorrected near visual acuity(UNVA),defocus curve,amplitude of accommodation(AMP),positive relative accommodation(PRA),negative relative accommo-dation(NRA),binocular cross-cylinder(BCC),accommodative convergence/accommodation ratio(AC/A),rupture point at the near point of convergence(NPC),near-far distance positive fusional vergence(PFV)and negative fusional vergence(NFV)rupture points,and near-far distance stereopsis of patients in the four groups were recorded and compared during the 3-month follow-up.Results After three months of follow-up,there was no significant difference in UDVA among the four groups(P＞0.05),while the UNVA of patients in the multifocal group and the mixed group was better than that in the control group and the monofocal group(all P＜0.05).The defocus curves of patients in the mixed group and the multifocal group were bimodal.There were statistically significant differences in AMP,NRA,PRA,and BCC among the four groups(all P＜0.05).There was no statistically significant difference in the AC/A ratio and far-distance NFV and PFV rupture points among the four groups(all P＞0.05).There were statistically significant differences in NPC rupture point and near-distance NFV and PFV rupture points among the four groups(all P＜0.05).There was no statistically significant difference in the proportion of patients with normal far-distance stereopsis among the four groups(P＞0.05).The proportion of pa-tients with normal near-distance stereopsis in the mixed group was significantly lower than that in the other three groups(all P＜0.05).Conclusion Multifocal IOL can effectively improve postoperative UDVA and UNVA in cataract patients.Binocular implantation of multifocal IOL is beneficial to the reconstruction of binocular visual function in far-and near-dis-tance conditions after cataract surgery.The mixed implantation of monofocal and multifocal IOL affects the recovery of near-distance binocular stereopsis in the short term.
