Objective To compare the efficacy and safety of transurethral blue laser vaporization of the prostate, transurethral resection of the prostate (TURP) or plasmakinetic resection of the prostate in the treatment of benign prostatic hyperplasia (BPH). Methods The domestic and foreign clinical studies on transurethral blue laser vaporization of the prostate (observation group), TURP or plasmakinetic resection of the prostate (control group) in the treatment of BPH during Jan. 2015 and Mar. 2025 were retrieved. The data were extracted with Cochrane systematic review method. The operation time, decrease in hemoglobin, bladder irrigation time, catheter indwelling time, total complication rate, retrograde ejaculation rate and urinary incontinence rate of the two groups were compared with RevMan 5.3.0 statistical software. Results A total of 5 Chinese studies involving 491 patients (248 in the observation group and 243 in the control group) were included in the Meta-analysis. Compared with the control group, the observation group had shorter operation time [MD=-20.80, 95%CI:-26.88—-14.72, P＜0.00001], less decrease in hemoglobin [MD=-10.61, 95%CI: -20.21—-1.01, P=0.03], shorter bladder irrigation time [MD=-17.85, 95%CI: -32.62—-3.09, P=0.002], shorter catheter indwelling time [MD=-1.71, 95%CI: -2.81—- 0.62, P=0.002], lower total complication rate [OR=0.11, 95%CI: 0.06—0.21, P＜0.00001], lower retrograde ejaculation rate [OR=0.05, 95%CI: 0.02—0.16, P＜0.00001] and lower urinary incontinence rate [OR=0.24, 95%CI: 0.07—0.79, P=0.02]. There were no significant differences in other complications between the two groups (P＞0.05). The international erectile function score (IIEF-5) of the observation group was significantly higher than that of the control group [MD=1.87, 95%CI:1.16—2.57, P＜0.00001]. There were no significant differences in international prostate symptom score (IPSS), maximum urinary flow rate (Qmax) and post-voiding residual (PVR) between the two groups (P＞0.05). Conclusion All three surgical procedures can effectively improve the lower urinary tract symptoms of BPH patients. Compared with TURP or plasmakinetic resection of the prostate, transurethral blue laser vaporization of the prostate has obvious advantages in terms of perioperative recovery, reduction of total complications, urinary incontinence and retrograde ejaculation rates, and preservation of sexual function.

Objective To evaluate the application effect of modified jejunostomy in thoracoscopic Ivor-Lewis esophagectomy. Methods A retrospective analysis of patients who underwent Ivor-Lewis esophagectomy for middle and lower esophageal cancer from 2017 to 2023 in Department of Cardiothoracic Surgery, Anqing Municipal Hospital was performed. The patients from 2017 to 2020 receiving "C+I" in the upper jejunum according to the "C+I" model, with fistula fixed with only two purse-string sutures and the abdominal wall were allocated into a group A. The patients from 2021 to 2023, on the basis of "C+I" suture, with the jejunum and abdominal wall fixed with 3-0 absorbable thread for 1-2 needles at the proximal or distal end of the fistula 10-15 mm, and the upper jejunum and abdominal wall fixed into "curtain" were allocated into a group B. The operation time, jejunostomy time, postoperative pathological stage, and enteral nutrition-related complications such as the incidence of incomplete intestinal obstruction, closed loop intestinal obstruction and intestinal volvulus requiring secondary surgery, skin redness and swelling of intestinal fluid leakage, stoma tube blockage, and accidental extubation were compared between the two groups. Results A total of 243 patients were enrolled in this study. The group A consisted of 118 patients (72 males, 46 females) with a mean age of (64.58±6.30) years. The group B consisted of 125 patients (76 males, 49 females) with a mean age of (65.11±6.81) years. All patients successfully underwent thoracoscopic Ivor-Lewis esophagectomy without perioperative mortality. There were no statistical differences between the two groups in operative time, jejunostomy creation time, or the rate of feeding tube occlusion (P>0.05). However, statistical differences were observed in the incidence of incomplete intestinal obstruction (P=0.035) and closed-loop intestinal obstruction requiring reoperation (P=0.017). The incidence of complications at the stoma site, such as intestinal fluid leakage and redness/swelling, was significantly higher in the group A (n=36) than that in the group B (n=7) (P<0.001). Conclusion The modified jejunostomy can significantly reduce the incomplete intestinal obstruction, closed loop intestinal obstruction and secondary operation rate after "C+I" jejunostomy, and significantly improve the leakage of intestinal fluid at the stoma and the injury of surrounding skin and soft tissue. Improvements in certain technologies reduce operational difficulties.

ObjectiveTo study the effect of Taikong Yangxin Pills on the metabolism of simulated weightless rats based on metabolomics and discuss the metabolism mechanism. MethodsIn the simulated space capsule environment on the ground， the rat model of simulated weightlessness was established by the tail suspension method. Rats were randomly grouped as follows： out-of-capsule control， in-capsule control， model， and high （3.0 g·kg^-1） and low （1.5 g·kg^-1） doses of Taikong Yangxin Pills， and they were administrated with corresponding drugs by gavage for 28 days. The serum levels of endogenous metabolites in rats were determined by ultra-performance liquid chromatography-quadrupole time-of-flight mass spectrometry （UPLC-Q-TOF/MS）. The obtained data were processed by principal component analysis （PCA） and orthogonal partial least squares-discriminant analysis （OPLS-DA） to screen for differential metabolites and potential biomarkers. MetaboAnalyst 5.0 was used for pathway enrichment analysis to explain the metabolic regulation mechanism of the drug. ResultsCompared with the out-of-capsule control group， the in-capsule control group showed elevated levels of thirteen metabolites， including 14-hydroxyhexadecanoic acid， linoleic acid， and α-linolenic acid （P<0.05）， which suggested that the space capsule environment mainly affected the metabolism of α-linolenic acid and linoleic acid in the rats. Compared with the in-capsule control group， the model group showed lowered levels of fourteen metabolites， including 4-imidazolone-5-propionic acid， isocitric acid/citric acid， and L-tyrosine （P<0.05）， which were recovered after the treatment with Taikong Yangxin pills （P<0.05）. The pathway enrichment analysis revealed that weightlessness induced by tail suspension and drug intervention mainly involved the phenylalanine， tyrosine， and tryptophan biosynthesis， tyrosine metabolism， histidine metabolism， and citric acid cycle. ConclusionThe simulated space capsule environment and simulated weightlessness induced by tail suspension can both affect the metabolism level of rats. Taikong Yangxin pills can ameliorate the metabolic abnormality in the rat model of weightlessness by regulating various amino acids and energy metabolism-related pathways.

We surveyed tick species and their carried pathogens for three important emerging zoonotic diseases(Babesiosis,Lyme disease,and fever with thrombocytopenia syndrome)at border areas between China and Mongolia,to provide data support for the construction of a database on cross-border transmission of important tick-borne diseases and the prevention and control of zoonotic tick-borne diseases in border areas.In 2023-2024,tick samples were collected from 12 border areas along the Sino-Mongolian bor-der,and tick species were identified according to morphology and molecular biology,then tested for the pathogens of three newly emerging zoonotic diseases with real-time fluorescence quantitative PCR and conventional PCR.Positive samples were verified through gene sequencing.A total of 2 477 ticks of five genera and nine species were collected from the border areas of China and Mongolia.The dominant tick species were identified as the grassland leatherback tick,the full-groove tick,and the small glaucous-eyed tick.The overall positivity rates of ticks carrying Babesia,Lyme disease spirochetes,and fever with thrombocytopenia virus in the 12 border ar-eas were 8.32%,11.59%,and 0%,respectively.Babesia,the most widely distributed tick species,was detected in ticks at eight areas in the eastern,central,and western parts of the China-Mongolia border.This species was found in eastern,central,and western ports along the Sino-Mongolian border;showed tick positivity rates of 0.37%-38.82%;and was most frequently carried by full-groove hard ticks.Spirochetes of Lyme disease were the next most widely distributed,and were detected in samples from four port areas,primarily in the eastern ports along the Sino-Mongolian border;97.2%of positive samples were detected in full-groove hard ticks.Zoonotic Babe-sia spp.were widely distributed in the border crossing areas of China and Mongolia,and included five species of Babesia microti,Ba-besia venatorum,and Babesia divergens,whereas the Lyme disease spirochetes were prevalent mainly in the east,including five geno-types of Borreliella garinii,Borreliella afzelii,and Borrelia burgdorferi sensu stricto.Co-infection with Babesia and Lyme disease spiro-chetes was present in hard ticks throughout the groove,and co-infected samples accounted for 74.27%of Babesia positive and 53.31%of Lyme disease positive samples.Thus,Babesia and Lyme disease spirochetes were found to be important tick-borne emerging zoo-notic pathogens in the Sino-Mongolian border crossing areas,the infected ticks were primarily full-grooved hard ticks,and co-infections were found.

Objective To observe the value of artificial intelligence iterative reconstruction(AIIR)for abdominal and pelvic CT examination after total hip arthroplasty(THA).Methods Totally 64 patients after THA who underwent abdominal and pelvic CT examinations were retrospectively collected,including 31 patients received routine CT scanning and 33 patients received dual-energy CT scanning.AIIR and hybrid iterative reconstruction(HIR)algorithms were used to obtain AIIR and HIR images based on conventional CT images,respectively,while 70-140 keV(interval of 5 keV)virtual monoenergetic images(VMI)were reconstructed based on dual-energy CT images.VMI with the best comprehensive imaging qualities were selected for analysis.Subjective scores and objective evaluation results of imaging quality were compared among different kinds of images.Results The subjective scores of artifacts,bones,diagnostic confidence,as well as displaying of pelvic organs and blood vessels on both AIIR images and VMI were all higher than those of HIR images(all P＜0.001),while no significant difference was found between AIIR images and VMI(all P＞0.017).Pairwise comparison of high-density artifact fraction and skeletal artifact fraction on AIIR,HIR images and VMI showed significant differences(all P＜0.001).No significant difference of low density artifact fraction nor high density noise fraction was detected between AIIR image and VMI(both P＞0.017),and the objective evaluation results were different from those of HIR images(both P＜0.017).The low density noise fraction of AIIR images was lower than that of HIR images(P＜0.017),while no significant difference was found between AIIR or HIR images and VMI(both P＞0.017).The bone noise fraction of AIIR and HIR images were both higher than that of VMI(both P＜0.017),while no significant difference was found between these two kinds of images(P＞0.017).Conclusion AIIR could reduce artifacts and image noise of abdominal and pelvic CT examination after THA and improve imaging quality.

BACKGROUND:Defective outgrowth of chondrocyte mitophagy causes degenerative chondrocyte pathological changes such as apoptosis and matrix loss.OBJECTIVE:To investigate the effects and possible mechanism of Juanbi Decoction-containing serum on interleukin-1β-induced inflammatory response and apoptosis of rat knee joint chondrocytes.METHODS:Fifty male Sprague-Dawley rats were randomly given saline,Juanbi Decoction in low,medium and high doses(1.24,2.48 and 4.96 g/kg),and celecoxib(positive drug)group.Drug-containing serum was obtained by continuous gavage for 2 weeks.(1)Chondrocytes were isolated and randomly divided into control group,interleukin-1β group,Juanbi Decoction low,medium and high dose containing serum groups and positive drug serum group.Cell counting kit-8 assay was used to detect cell viability;immunofluorescence double staining was used to detect mitophagy level;immunofluorescence was used to detect the phosphorylated AMP-activated protein kinase level;western blot was used to detect the expression of PTEN induced putative kinase 1/Parkin pathway-related protein and cleaved caspase-3;and ELISA was used to detect inflammatory factor level.(2)PTEN induced putative kinase 1 siRNA and Compound C were used for intervention to explore the role of AMP-activated protein kinase/PTEN induced putative kinase 1/Parkin pathway in the regulation of mitophagy by Juanbi Decoction-containing serum.RESULTS AND CONCLUSION:(1)Compared with the control group,chondrocyte survival,type II collagen,phosphorylated AMP-activated protein kinase,PTEN induced putative kinase 1,Parkin,and microtubule-associated proteins 1 light chain 3 protein levels,and mitophagy levels were significantly lower in the interleukin-1β group(P<0.05),while cleaved caspase-3 protein levels,interleukin-6,interleukin-8 and tumor necrosis factor-α levels were significantly higher(P<0.05).Compared with the interleukin-1β group,opposite changes in all the above indexes were observed in Juanbi Decoction low,medium and high dose containing serum groups and positive drug serum group(P<0.05).(2)PTEN induced putative kinase 1 siRNA significantly inhibited the effect of Juanbi Decoction-containing serum on mitophagy in interleukin-1β-treated chondrocytes and reduced the protective effect of Juanbi Decoction-containing serum on interleukin-1β-induced inflammation and apoptosis in chondrocytes;Compound C reversed the effect of Juanbi Decoction-containing serum on the PTEN induced putative kinase 1/Parkin signaling pathway in interleukin-1β-treated chondrocytes.To conclude,Juanbi Decoction-containing serum inhibits chondrocyte inflammation and apoptosis by affecting the level of mitochondrial autophagy,thereby attenuating interleukin-1β-induced chondrocyte degradation by a mechanism that may be related to the regulation of the AMP-activated protein kinase/PTEN induced putative kinase 1/Parkin pathway.

BACKGROUND: Arsenic trioxide (ATO) is indicated as a broad-spectrum medicine for a variety of diseases, including cancer and cardiac disease. While the role of ATO in hepatic ischemia/reperfusion injury (HIRI) has not been reported. Thus, the purpose of this study was to identify the effects of ATO on HIRI. METHODS: In the present study, we established a 70% hepatic warm I/R injury and partial hepatectomy (30% resection) animal models in vivo and hepatocytes anoxia/reoxygenation (A/R) models in vitro with ATO pretreatment and further assessed liver function by histopathologic changes, enzyme-linked immunosorbent assay, cell counting kit-8, and terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling (TUNEL) assay. Small interfering RNA (siRNA) for extracellular signal-regulated kinase (ERK) 1/2 was transfected to evaluate the role of ERK1/2 pathway during HIRI, followed by ATO pretreatment. The dynamic process of autophagic flux and numbers of autophagosomes were detected by green fluorescent protein-monomeric red fluorescent protein-LC3 (GFP-mRFP-LC3) staining and transmission electron microscopy. RESULTS: A low dose of ATO (0.75 μmol/L in vitro and 1 mg/kg in vivo ) significantly reduced tissue necrosis, inflammatory infiltration, and hepatocyte apoptosis during the process of hepatic I/R. Meanwhile, ATO obviously promoted the ability of cell proliferation and liver regeneration. Mechanistically, in vitro  studies have shown that nontoxic concentrations of ATO can activate both ERK and phosphoinositide 3-kinase-serine/threonine kinase (PI3K-AKT) pathways and further induce autophagy. The hepatoprotective mechanism of ATO, at least in part, relies on the effects of ATO on the activation of autophagy, which is ERK-dependent. CONCLUSION Low, non-toxic doses of ATO can activate ERK/PI3K-AKT pathways and induce ERK-dependent autophagy in hepatocytes, protecting liver against I/R injury and accelerating hepatocyte regeneration after partial hepatectomy.
