Objective:To explore the impact of diabetes mellitus on perioperative myocardial injury and cardiac function recovery in patients undergoing off-pump coronary artery bypass grafting (CABG).Methods:The clinical data of 40 patients with coronary heart disease who underwent off-pump CABG in Changsha Central Hospital from 2015 to 2025 were retrospectively included. They were divided into the diabetes group (20 cases) and the control group (20 cases) according to whether they had type 2 diabetes mellitus. Myocardial injury markers (creatine kinase isoenzyme, troponin I, lactate dehydrogenase) before surgery, on the 1st and 3rd days after surgery and before discharge, as well as cardiac function indicators (B-type natriuretic peptide, left ventricular ejection fraction) before surgery and before discharge were compared between the two groups. The postoperative recovery speed (mechanical ventilation time, intensive care unit stay, vasoactive drug use time, postoperative hospital stay) was also compared between the two groups.Results:Before surgery, there were no statistically significant differences in myocardial injury markers and cardiac function indicators between the two groups (all P>0.05). On the 3rd day after surgery, lactate dehydrogenase in the diabetes group was significantly higher than that in the control group ( P<0.05), while there were no statistically significant differences in creatine kinase isoenzyme and troponin I between the two groups (all P>0.05). Before discharge, the levels of creatine kinase isoenzyme and B-type natriuretic peptide in the diabetes group were significantly higher than those in the control group (all P<0.05), and the left ventricular ejection fraction was significantly lower than that in the control group ( P<0.05). Compared with the control group, the diabetes group had significantly longer mechanical ventilation time, intensive care unit stay, and postoperative hospital stay (all P<0.05), but there was no statistically significant difference in the use time of vasoactive drugs ( P>0.05). Conclusions:For patients with coronary heart disease complicated with diabetes mellitus, their preoperative cardiac status is comparable to that of patients without diabetes mellitus, but they show a characteristic dynamic injury pattern after surgery: early elevation of lactate dehydrogenase suggests susceptibility to subcellular injury, and long-term abnormalities of creatine kinase isoenzyme, B-type natriuretic peptide, and decrease in left ventricular ejection fraction indicate myocardial repair disorders. Compared with patients without diabetes mellitus, those with diabetes mellitus require a longer recovery time after off-pump CABG, and targeted perioperative management strategies are urgently needed.

ObjectiveTo investigate the effect and mechanism of polysaccharide in water extract of Cyclocarya paliurus （CPWP） in inhibiting benign prostatic hyperplasia （BPH）. MethodsCPWP was obtained by heating reflux， aqueous extraction， alcohol precipitation， and freeze drying. The chemical composition and structural properties of CPWP were analyzed by high performance liquid chromatography with 1-pheny-3-methyl-5-pyrazolone pre-column derivatization and infrared spectroscopy. Male SD rats were randomly assigned into control， model， finasteride （ig 5 mg·kg^-1）， and low-， medium-， and high-dose （ig 50， 75， 100 mg·kg^-1） CPWP groups， with 8 rats in each group. The BPH model was established by subcutaneously injecting propionate testosterone in castrated rats. The rats in the drug intervention groups were administrated with corresponding drugs， and those in the control group were administrated with an equal volume of normal saline each day. After 30 consecutive days， the rats were sacrificed， and the prostate tissue was separated and weighed. The effects of drug interventions on the body weight， prostate wet weight， and prostate index of rats were examined. The prostate tissue was stained with hematoxylin-eosin （HE） for observation of pathological changes. Enzyme-linked immunosorbent assay was employed to measure the level of dihydrotestosterone （DHT）， and immunohistochemical staining was used to detect the expression of steroid 5 alpha-reductase 2 （SRD5A2） and Ki67 in the prostate tissue. ResultsCPWP was identified as a saccharide， with characteristic absorption peaks of saccharides. CPWP showed the total sugar content of 44.15% and molecular weight within the range of 5.5-78.8 kDa， being composed of mannose， rhamnose， galacturonic acid， glucose， galactose， xylose， and arabinose. Compared with the control group， the model group had significantly increased prostate wet weight and prostate index （P<0.01）， thick and tall prostate epithelial cells， increased internal wrinkles， papillary expansion into the cavity， an elevation in DHT level in the serum， and up-regulated expression of SRD5A2 and Ki67 in the prostate tissue （P<0.05， P<0.01）. Compared with the model group， both the finasteride and CPWP groups showed decreases in prostate wet weight and prostate index （P<0.05， P<0.01）， thinned prostate epithelial cells， with only a small portion of internal wrinkles and papillary expansion into the cavity， shortened papillary protrusions， lowered DHT level in the serum， and down-regulated expression of SRD5A2 and Ki67 in the prostate tissue （P<0.01）. Moreover， CPWP exerted effects in a dose-dependent manner. ConclusionCPWP inhibits BPH by regulating the expression of SRD5A2.

Purpose To characterize the clinicopathological features of gastrointestinal mesenchymal tumors(GMTs)resected via endoscopic techniques.Methods A retrospective analysis was conducted on 495 cases of endo-scopically resected GMTs.Clinical information,histomorphological findings,immunohistochemical profiles,and mo-lecular characteristics were reviewed.Results The cohort included 495 patients aged 20-78 years(median:53 years).The majority of tumors were located in the stomach(58.8％)and esophagus(36.8％).Histologically,most tumors consisted of spindle cells,with a minority composed of epithelioid cells;fibrocollagenous or myxoid stroma was occasionally observed.Immunohistochemically,leiomyomas showed diffuse positivity for α-SMA(98.8％)and desmin(99.3％),gastrointestinal stromal tumors(GISTs)expressed CD117(99.4％),DOG1(97.6％),and CD34(97.0％),and schwannomas were positive for S-100(93.7％).The predominant tumor types were leiomyomas(54.1％)and GISTs(33.7％),while the remaining 12.2％comprised other rare types.Various endoscopic resection techniques were employed based on the tumors' anatomical depth,including endoscopic submucosal dissection(ESD,40.5％),submucosal tunneling endoscopic resection(STER,17.1％),endoscopic mucosal resection(EMR,16.5％),endoscopic full-thickness resection(EFTR,13.9％),and endoscopic submucosal excavation(ESE,12.0％).EMR and ESD were primarily used for superficial lesions,while deeper tumors with were more often treated with STER,EFTR,and ESE.The rate of negative resection margins was lower in GISTs(72.2％)and other tumors with indistinct margins,compared to leiomyomas(92.6％)and those with well-defined boundaries.Conclusion Leiomyomas and GISTs are the most common gastrointestinal mesenchymal tumors resected via endoscopy.A variety of resection techniques are applicable depending on tumor location and depth.Accurate pathological diagnosis should be based on HE morphology,supplemented by endoscopic findings,margin status,immunohistochemistry,and necessary molecular tests.

Objective:To investigate the expression of DNA polymerase δ catalytic subunit gene 1(POLD1)in bladder cancer tissues and its correlation with patients'clinicopathological characteristics and prognosis,and to explore its effect on the proliferation,migration,and invasion of bladder cancer 5637 cells.Methods:Sixty cases of bladder cancer tissues and paired adjacent noncancerous tissues preserved in the Department of Pathology,Shanxi Bethune Hospital,from January to June 2021 were collected.Immunohistochemistry was performed to detect POLD1 protein expression in bladder cancer tissues.Patients were divided into high-and low-expression groups according to POLD1 levels,and the correlations between POLD1 level with clinicopathological characteristics and prognosis were analyzed.Bladder cancer 5637 cells were cultured routinely and divided into a control group(untransfected),a sh-NC group(transfected with sh-NC-GFP lentivirus vector),and a sh-POLD1 group(transfected with sh-POLD1-GFP lentiviral vector).Transfection efficiency was validated using fluorescence microscopy and WB method.Cell proliferation,migration,and invasion were assessed using CCK-8,wound-healing,and Transwell assays.5637 cell-transplanted tumor experiment was performed to detect the effect of POLD1 knockdown on the growth of transplanted tumors.Results:POLD1 was highly expressed in bladder cancer tissues(P<0.05).High POLD1 expression was significantly associated with advanced clinical stage and pathological grade(all P<0.05).Patients with high POLD1 expression exhibited shorter progression-free survival,reduced overall survival,lower 3-year survival rate,and higher recurrence and metastasis rate(all P<0.05).The expression of POLD1 was successfully knocked down in 5637 cells,which significantly inhibited the proliferation,migration,and invasion abilities of 5637 cells(all P<0.05).In vivo,POLD1 knockdown significantly inhibited the growth of transplanted tumors(P<0.05).Conclusion:POLD1 is highly expressed in bladder cancer tissues,and its upregulation is associated with tumor stage,pathological grade,and patient prognosis.POLD1 knockdown can inhibit the malignant biological behaviors of bladder cancer cells.

AIM:To analyze the Pharmaceutical Care Network Europe(PCNE)classification system used for evaluating the drug related problems(DRPs)of tacrolimus concentration fluctuations in kidney transplant recipients.METHODS:Kidney transplant recipients were selected as the study subjects,who experienced fluctuations in tacrolim-us blood concentrations and clinical pharmacist in-tervention during outpatient follow-up.PCNE(9.0)classification system was used to evaluate the DRPs of tacrolimus.And the DRP problems,causes,inter-vention plans,acceptance and status were ana-lyzed.RESULTS:A total of 700 kidney transplant re-cipients were enrolled from July 2019 to December 2021,and 1014 DRPs were found.The problems of DRPs included the occurrence of adverse drug events(P2.1,60.16％)and poor treatment out-comes(P1.2,39.84％);The main reasons included dosage selection(C3,43％),others(C9,38.4％),and drug selection(C1,9.41％);Clinical pharmacists ac-tively intervened at the recipient level(I2,98.92％)and drug level(I3,1.08％);The acceptance rate of the intervention plan(A1.1+A1.3)reached 98.62％,and the complete implementation rate(A1.1)reached 72.09％;79.29％of DPRs were fully or par-tially resolved(O1.1 and O2.1).CONCLUSION:Clini-cal pharmacists can use PCNE to evaluate tacrolim-us therapeutic drug monitoring(TDM)related DRPs,help standardize TDM pharmaceutical ser-vice models,standardize TDM abnormal result in-terpretation and intervention workflows,and pro-mote safe and rational drug utilization.

AIM:To understand the efficacy and safety of amikacin(AMK)for the treatment of car-bapenem-resistant Klebsiella pneumoniae pneu-moniae(CRKP)in preterm infants and to establish a management process for the use of amikacin in preterm infants.METHODS:CRKP-infected preterm infants treated with amikacin between January 2019 and December 2021 were retrospectively ana-lyzed,and parametric data paired t-tests were used to assess the efficacy and safety of amikacin for the included infectious and safety indicators,and to es-tablish a management process for amikacin use in preterm infants.RESULTS:Eight cases of CRKP in-fection were included,with the main diagnosis of pneumonia and sepsis.eight preterm infants were screened for the AMK ototoxicity gene mitochon-drial gene MT-RNR1(MT-RNR1 1494C＞T and MT-RNR11555A＞G)before amikacin treatment,and none of them were found to have the gene variant.after receiving amikacin sulphate injection treat-ment for 7 days,the indicators of infectivity were improved,and was statistically significant(P＜0.01).No clinical ototoxicity or nephrotoxicity was ob-served in the children before or after treatment.CONCLUSION:Aminoglycosides are still the main antibiotics used for the empirical treatment of sus-pected infections in preterm infants,especially drug-resistant bacterial infections.Despite the risk of ototoxicity and nephrotoxicity,we provide man-agement procedures and recommendations for neonatal treatment with amikacin to reduce the risk of ototoxicity and nephrotoxicity in AMK.
