ABSTRACT Introduction: We aim to compare the safety and effectiveness of the KangDuo (KD)-Surgical Robot-01 (KD-SR-01) system and the da Vinci (DV) system for robot-assisted radical nephroureterectomy (RARNU). Materials and Methods: This multicenter prospective randomized controlled trial was conducted between March 2022 and September 2023. Group 1 included 29 patients undergoing KD-RARNU. Group 2 included 29 patients undergoing DV-RARNU. Patient demographic and clinical characteristics, perioperative data, and follow-up outcomes were collected prospectively and compared between the two groups. Results: There were no significant differences in patient baseline demographic and preoperative characteristics between the two groups. The success rates in both groups were 100% without conversion to open or laparoscopic surgery or positive surgical margins. No significant difference was observed in docking time [242 (120-951) s vs 253 (62-498) s, P = 0.780], console time [137 (55-290) min vs 105 (62-220) min, P = 0.114], operative time [207 (121-460) min vs 185 (96-305) min, P = 0.091], EBL [50 (10-600) mL vs 50 (10-700) mL, P = 0.507], National Aeronautics and Space Administration Task Load Index scores, and postoperative serum creatinine levels between the two groups. None of the patients showed evidence of distant metastasis, local recurrence, or equipment-related adverse events during the four-week follow-up. One (3.4%) patient in Group 2 experienced postoperative enterovaginal and enterovesical fistulas (Clavien-Dindo grade III). Conclusions: The KD-SR-01 system is safe and effective for RARNU compared to the DV Si or Xi system. Further randomized controlled studies with larger sample sizes and longer durations are required.

ABSTRACT Banana stalk production for fiber is an important crop activity in southern China. The fiber extraction technology used has a great impact on the effectiveness and quality of the fiber from banana stalks. A mechanical model of the process for banana stalk fiber extraction was developed through theoretical analysis. The existing problems of machines for banana stalk fiber extraction include high rates of fiber impurity and damaged fibers. A 3-factor 3-horizon orthogonal rotation combination test was established. The rates of fiber impurity and damaged fibers were the evaluation indices. The significant order of the factors determining the rate of fiber impurity, from largest to smallest, was the gap between the scraper and the holding plate, the number of scrapers, and the rotational speed of the scraping knives roller. The significant order of factors for the rate of damaged fiber was the gap between the scraper, the rotational speed of the scraping knives roller, and the number of scrapers. The optimized banana straw fiber extraction machine was tested in the field. The results show that the development of this model can provide valuable experience and references for understanding and improving other similar agricultural machinery and equipment.

Abstract Objective To analyze the effect of mast cells (MCs) in neurogenic inflammation and the neuroimmune response of trigeminal ganglia (TG) due to pulpitis and detect the regulatory effect of curcumin (Cur) on neuroimmune responses induced by pulpitis. Methodology Immunohistochemistry, toluidine blue staining (TB), and other methods were used to detect the dynamic changes of MCs, as well as tryptase expression changes and protease activated receptor 2 (PAR2) and calcitonin gene-related peptide (CGRP) levels in the neuroimmune response induced by pulpitis. After administering Cur by intraperitoneal injection, the expression levels of Toll-like receptor 4 (TLR4), CGRP, glial fibrillary acidic protein (GFAP), fractalkine (CX3CL1), Tumor necrosis factor (TNF-α), and other factors were examined in the TG of pulpitis-induced rats. Results After pulpitis induction, the expression of CGRP-positive neurons and GFAP-positive soluble guanylate cyclase (SGC) in the TG significantly increased. A large number of MCs underwent degranulation. MCs were scattered between the CGRP-positive nerve fibers. MCs showing a typical degranulated state within the TG significantly increased and tryptase-positive MCs surrounded the TG nerve fibers and neurons. After treatment with Cur, the inflammatory response in the periodontal bone induced by pulpitis decreased and promoted early tissue repair. The expression of TNF-α significantly decreased as did degranulation of MCs. In contrast, the expression of CGRP, TLR4-positive neurons, activated SGCs, and PAR2-positive TG neurons significantly decreased. MCs could participate in the neuroimmune response induced by pulpitis by the tryptase signaling pathway. Conclusion Importantly, Cur inhibited the degranulation of MCs, downregulated the expression of tryptase and PAR2 in the TG, and attenuated the activation response of osteoclasts in the apical periodontium.

Early and accurate diagnosis of acute graft-versus-host disease (aGVHD) after allogeneic hematopoietic stem cell transplantation is crucial for the prognosis of patients. This study identified a potential biomarker for the severity of aGVHD after human leukocyte antigen (HLA)-haploidentical peripheral blood hematopoietic stem cell transplantation (haplo-PBSCT). We included 20 healthy subjects and 57 patients who underwent haplo-PBSCT. Of these patients, 22 developed aGVHD after haplo-PBSCT. The results showed that patients with aGVHD had significantly increased levels of Tim-3+/Perforin+/Granzyme B+CD8+ T cells, but significantly decreased Galectin-9. The differences in Galectin-9 and Tim-3+/Granzyme B+CD8+ T cells between grade I-II aGVHD and III-IV aGVHD were also significant. In vitro, the apoptosis of CD8+ T cells from aGVHD patients was significantly increased after Tim-3/Galectin-9 pathway activation, which decreased Granzyme B secretion. As revealed by univariate analysis, the level of Tim-3+CD8+ T cells was a risk factor for severe aGVHD. ROC analysis demonstrated that high levels of Tim-3+CD8+ T cells had a significant diagnostic value for severe aGVHD, with an area under the curve of 0.854 and cut-off value of 14.155%. In conclusion, the binding of Tim-3 with exogenous Galectin-9 can promote apoptosis of CD8+ T cells and affect the secretion of Granzyme B. Tim-3+CD8+ T cells have the potential to serve as immunological markers for assessing the severity of aGVHD after haplo-PBSCT and identifying patients at a higher risk for severe aGVHD. graftversushost graft versus host (aGVHD HLAhaploidentical HLA haploidentical haploPBSCT. haploPBSCT haplo PBSCT .

Abstract Objective To investigate the value of a nomogram based on multiparametric and multiregional MR images to predict Isocitrate Dehydrogenase-1 (IDH1) gene mutations in glioma. Data and methods The authors performed a retrospective analysis of 110 MR images of surgically confirmed pathological gliomas; 33 patients with IDH1 gene Mutation (IDH1-M) and 77 patients with Wild-type IDH1 (IDH1-W) were divided into training and validation sets in a 7:3 ratio. The clinical features were statistically analyzed using SPSS and R software. Three glioma regions (rCET, rE, rNEC) were outlined using ITK-SNAP software and projected to four conventional sequences (T1, T2, Flair, T1C) for feature extraction using AI-Kit software. The extracted features were screened using R software. A logistic regression model was established, and a nomogram was generated using the selected clinical features. Eight models were developed based on different sequences and ROIs, and Receiver Operating Characteristic (ROC) curves were used to evaluate the predictive efficacy. Decision curve analysis was performed to assess the clinical usefulness. Results Age was selected with Radscore to construct the nomogram. The Model 1 AUC values based on four sequences and three ROIs were the highest in these models, at 0.93 and 0.89, respectively. Decision curve analysis indicated that the net benefit of model 1 was higher than that of the other models for most Pt-values. Conclusion A nomogram based on multiparametric and multiregional MR images can predict the mutation status of the IDH1 gene accurately.

Abstract Introduction: Long QT Syndrome (LQTS) is an inherited disease with an abnormal electrical conduction system in the heart that can cause sudden death as a result of QT prolongation. LQT2 is the second most common subtype of LQTS caused by loss of function mutations in the potassium voltage-gated channel subfamily H member 2 (KCNH2) gene. Although more than 900 mutations are associated with the LQTS, many of these mutations are not validated or characterized. Methods and results: Sequencing analyses of genomic DNA of a family with LQT2 identified a putative mutation. i.e., KCNH2(NM_000238.3): c.3099_3112del, in KCNH2 gene which appeared to be a definite pathogenic mutation. The family pedigree information showed a gender difference in clinical features and T-wave morphology between male and female patients. The female with mutation exhibited recurring ventricular arrhythmia and syncope, while two male carriers did not show any symptoms. In addition, T-wave in females was much flatter than in males. The female proband showed a positive reaction to the lidocaine test. Lidocaine injection almost completely blocked ventricular arrhythmia and shortened the QT interval by ≥30 ms. Treatment with propranolol, mexiletine, and implantation of cardioverter-defibrillators prevented the sustained ventricular tachycardia, ventricular fibrillation, and syncope, as assessed by a 3-year follow-up evaluation. Conclusions: A putative mutation c.3099_3112del in the KCNH2 gene causes LQT2 syndrome, and the pathogenic mutation mainly causes symptoms in female progeny.

Abstract Pea sprouts are derived from sprouted peas and are popular for their high vitamin C and flavonoid content, as well as their rapid growth and ease of production. Enhancing its nutritional value with simple treatments is worth exploring, In the present study, we applied supplemental UV irradiation to pea sprouts and examined various components such as vitamin C and flavonoid substances in the treated pea sprouts. Meanwhile, to investigate the mechanism of action of UV irradiation on pea sprouts, we performed high-throughput RNA sequencing (RNA-Seq) analysis to probe the genome-wide expression profile of pea sprouts under UV irradiation, generating 41.90 Gb of Clean Data, the results were also validated by reverse transcription-polymerase chain reaction (RT-qPCR), and the raw data of sequencing were submitted to the SRA repository. Further transcriptome analysis showed that UV irradiation significantly affected the expression of genes in metabolic pathways, especially those of some key enzymes that affect substance metabolism.

RESUMO OBJETIVO: Investigar os efeitos curativos da manipulação lombar com o movimento de puxar oblíquo combinado a terapia por exercícios de sling-training para dor lombar baixa crônica não específica. METODOLOGIA: Um total de 60 pacientes com dor lombar baixa crônica não específica no ambulatório foram incluídos neste estudo. Esses pacientes foram divididos aleatoriamente em dois grupos: o grupo de observação e o grupo de controle. O grupo de controle aderiu apenas à terapia por exercícios de sling-training três vezes por semana, enquanto o grupo de observação aderiu à manipulação lombar com o movimento de puxar oblíquo combinado à terapia por exercícios de sling-training uma vez por semana. O tratamento durou quatro semanas. RESULTADOS: (1) Antes e após o tratamento, o escore de ODI foi comparado no grupo. Uma significância estatística notável foi observada a partir do terceiro dia (P<0,05). No terceiro mês de acompanhamento, a diferença nos escores de ODI entre os dois grupos foi estatisticamente significante (P<0,05). (2) Antes e após o tratamento, observou-se que diferenças nos escores de VAS a partir do terceiro dia foram estatisticamente significantes (P< 0,05). (3) A diferença de força muscular entre os dois grupos apresentou significância estatística notável no terceiro mês de acompanhamento (p<0,05). CONCLUSÃO: A função de reabilitação efetiva da manipulação lombar com o movimento de puxar oblíquo combinada à terapia por exercícios de sling-training em pacientes com dor lombar baixa crônica não específica é superior à da terapia por exercícios de sling-training sozinha.

SUMMARY OBJECTIVE: To investigate clinical curative effects of lumbar oblique-pulling manipulation in combination with sling-exercise-therapy training on chronic nonspecific lower back pain. METHODS: A total of 60 patients with chronic nonspecific lower back pain in the Outpatient Department were included in this study. These patients were randomly divided into two groups: the observation group and the control group. The control group adopted a single sling-exercise-therapy training three times a week, while the observation group adopted lumbar oblique-pulling manipulation in combination with manipulation treatment once a week. The course of treatment lasted for four weeks. RESULTS: (1) Before and after treatment, the ODI score was compared within the group. A remarkable statistical significance was observed from the third day (P<0.05). At the third month of follow-up, the difference in ODI scores between these two groups was statistically significant (P<0.05). (2) Before and after treatment, it was observed that differences in VAS scores from the third day were statistically significant (P<0.05). (3) The difference in muscle strength between these two groups had remarkable statistical significance in the third month of follow-up (P<0.05). CONCLUSION: The effective rehabilitation function of lumbar oblique-pulling manipulation in combination with sling-exercise-therapy training in patients with CNLBP is superior to that of sling-exercise-therapy training alone.

RESUMO OBJETIVO: O objetivo deste estudo é investigar a expressão de Id-1 em tecidos de adenocarcinoma colorretal em humanos e investigar sua correlação com os parâmetros patológicos clínicos de câncer colorretal. MÉTODOS: Os níveis de expressão de proteína e mRNA Id-1 em 50 amostras de tecido colorretal normal e 50 amostras de tecido de adenocarcinoma colorretal foram detectados através de reação em cadeia de polimerase precedida de transcrição reversa e western blot. Além disso, a proteína Id-1 foi detectada através de imuno-histoquímica. A correlação entre a expressão de Id-1 e características clínico-patológicas foi analisada. RESULTADOS: O nível de expressão de mRNA Id-1 em tecidos de adenocarcinoma colorretal e tecidos colorretais normais foi de 0,96 ± 0,03 versus 0,20 ± 0,04, respectivamente; a diferença foi estatisticamente significativa (P= 0,011). Além disso, a expressão da proteína Id-1 foi maior em tecidos de adenocarcinoma colorretal do que em tecidos colorretais normais (0,82 ± 0,04 versus 0,31 ± 0,02, P= 0,020). Além disso, a taxa de expressão positiva de proteínas Id-1 foi maior em tecidos de adenocarcinoma colorretal do que em tecidos colorretais normais (72,00% vs. 24,00%, X2=23,431, p=0,000). A expressão de Id-1 foi correlacionada com a profundidade da invasão tumoral, estágio TNM, metástases linfonodais, invasão vascular e metástase hepática (P<0,01). Todavia, essa expressão não se correlacionou com o tamanho do tumor e graus de diferenciação (P>0,05). CONCLUSÃO: A alta expressão de Id-1 em tecidos de adenocarcinoma colorretal desempenham um importante papel no processo do câncer, e é esperado que se torne um novo indicador de monitoramento de tumores para o diagnóstico clínico, tratamento e estimativa de prognóstico.

SUMMARY BACKGROUND: This study aims to investigate the expression of Id-1 in human colorectal adenocarcinoma tissues and explore its correlation with the clinical pathological parameters of colorectal cancer. METHODS: The Id-1 mRNA and protein expression levels of 50 specimens of normal colorectal tissues and 50 specimens of colorectal adenocarcinoma tissues were detected using reverse-transcription polymerase chain reaction and western blot. Furthermore, Id-1 protein was detected using immunohistochemistry. The correlation between the expression of Id-1 and clinicopathologic features was analyzed. RESULTS: The mRNA expression level of Id-1 in colorectal adenocarcinoma tissues and normal colorectal tissues was 0.96 ± 0.03 vs. 0.20 ± 0.04, respectively; and the difference was statistically significant (P=0.011). Furthermore, Id-1 protein expression was higher in colorectal adenocarcinoma tissues than in normal colorectal tissues (0.82 ± 0.04 vs. 0.31 ± 0.02, P=0.020). In addition, the positive protein expression rate of Id-1 was higher in colorectal adenocarcinoma tissues than in normal colorectal tissues (72.00% vs. 24.00%, X2=23.431, P=0.000). The expression of Id-1 was correlated with the depth of tumor invasion, TNM stage, lymph node metastasis, vessel invasion, and liver metastasis (P<0.01). However, this expression was not correlated with tumor size and differentiation degrees (P>0.05). CONCLUSIONS: The high Id-1 expression in colorectal adenocarcinoma tissues play an important role in the process of cancer, and is expected to become a new tumor monitoring indicator for clinical diagnosis, treatment, and prognosis judgment.

The aim of this study was to elucidate the concise effects of a traditional herb pair, Curcumae rhizoma-Sparganii rhizoma (CRSR), on uterine leiomyoma (UL) by analyzing transcriptional profiling. The UL rat model was made by intramuscular injection of progesterone and gavage administration of diethylstilbestrol. From 11 weeks of the establishment of the model, rats of the UL+CRSR group were gavaged daily with CRSR (6.67 g/kg). The serum concentrations of progesterone (P) and estradiol (E2) were determined by radioimmunoassay, the uterine index was measured by caliper measurement, and the pathological status was observed by hematoxylin and eosin stain. Gene expression profiling was checked by NimbleGen Rat Gene Expression Microarrays. The results indicated that the uterine mass of UL+CRSR rats was significantly shrunk and serum P and E2 levels significantly reduced compared to UL animals and nearly to the level of normal rats. Results of microarrays displayed the extensive inhibition of CRSR upon the expression of proliferation and deposition of extracellular matrix (ECM)-related genes, and significantly regulated a wide range of metabolism disorders. Furthermore, CRSR extensively regulated key pathways of the UL process, such as MAPK, PPAR, Notch, and TGF-β/Smad. Regulation of the crucial pathways for the UL process and ECM metabolism may be the underlying mechanisms of CRSR treatment. Further studies will provide clear clues for effectively treating UL with CRSR.

ABSTRACT Bombyx mori nucleopolyhedrovirus (BmNPV) disease is one of the most serious silkworm diseases, and it has caused great economic losses to the sericulture industry. So far, the disease has not been controlled effectively by therapeutic agents. Breeding resistant silkworm varieties breeding may be an effective way to improve resistance to BmNPV and reduce economic losses. A precise resistance-detection method will help to accelerate the breeding process. For this purpose, here we described the individual inoculation method (IIM). Details of the IIM include pathogen BmNPV preparation, mulberry leaf size, pathogen volume, rearing conditions, course of infection, and breeding conditions. Finally, a resistance comparison experiment was performed using the IIM and the traditional group inoculation method (GIM). The incidence of BmNPV infection and the within-group variance results showed that the IIM was more precise and reliable than the GIM.

In order to develop new-typed multifunctional composite nanofibers, PANI/Fe3O4/PVP flexible bifunctional composite nanofibers with simultaneous electrical conduction and magnetism have been successfully fabricated via a facile electrospinning technology. Polyvinyl pyrrolidone (PVP) is used as a matrix to construct composite nanofibers containing different amounts of polyaniline (PANI) and Fe3O4 nanoparticles (NPs). The bifunctional composite nanofibers simultaneously possess excellent electrical conductivity and magnetic properties. The electrical conductivity reaches up to the order of 10-3 S · cm-1. The electrical conductivity and saturation magnetization of the composite nanofibers can be respectively tuned by adding various amounts of PANI and Fe3O4 NPs. The obtained electricity-magnetism bifunctional composite nanofibers are expected to possess many potential applications in areas such as electromagnetic interference shielding, special coating, microwave absorption, molecular electronics and future nanomechanics. More importantly, the design concept and construct technique are of universal significance to fabricate other bifunctional one-dimensional nanostructures.

OBJETIVO: A cirurgia torácica vídeo-assistida (CTVA) tem sido uma intervenção de escolha para o tratamento de pneumotórax espontâneo (PS) com bolha pulmonar. Nosso objetivo foi apresentar uma abordagem de CTVA uniportal unilateral para bulectomia bilateral e avaliar sua eficácia terapêutica. MÉTODOS: Entre maio de 2011 e janeiro de 2012, cinco pacientes foram submetidos a bulectomia bilateral por essa abordagem. Todos apresentavam PS bilateral. A TCAR pré-operatória mostrou que todos os pacientes tinham bolhas bilaterais no pulmão apical. As indicações cirúrgicas, os procedimentos de operação e os desfechos foram revisados. RESULTADOS: Todos os pacientes foram submetidos com sucesso a essa abordagem para bulectomia bilateral, sem complicações intraoperatórias. A mediana de tempo para a retirada do dreno torácico foi de 4,2 dias, e a mediana do tempo de hospitalização no pós-operatório foi de 5,2 dias. A mediana de seguimento pós-operatório foi de 11,2 meses. Um paciente teve recidiva de PE do lado esquerdo três semanas após a cirurgia e foi submetido a abrasão pleural. CONCLUSÕES: A bulectomia bilateral utilizando CTVA uniportal combinada com acesso contralateral ao mediastino anterior é tecnicamente confiável e promove desfechos favoráveis para pacientes com PS que desenvolvem bolhas bilaterais no pulmão apical. Entretanto, para a realização desse procedimento cirúrgico, são necessários cirurgiões com experiência em CTVA, instrumentos toracoscópicos longos, entre outras exigências.

OBJECTIVE: Video-assisted thoracoscopic surgery (VATS) has been a surgical intervention of choice for the treatment of spontaneous pneumothorax (SP) with lung bulla. Our objective was to introduce a uniportal VATS approach for simultaneous bilateral bullectomy and to evaluate its therapeutic efficacy. METHODS: Between May of 2011 and January of 2012, five patients underwent bilateral bullectomy conducted using this approach. All of the patients presented with bilateral SP. Preoperative HRCT revealed that all of the patients had bilateral apical bullae. We reviewed the surgical indications, surgical procedures, and outcomes. RESULTS: All of the patients were successfully submitted to this approach for bilateral bullectomy, and there were no intraoperative complications. The median time to chest tube removal was 4.2 days, and the median length of the postoperative hospital stay was 5.2 days. The median postoperative follow-up period was 11.2 months. One patient experienced recurrence of left SP three weeks after the surgery and underwent pleural abrasion. CONCLUSIONS: Bilateral bullectomy through uniportal VATS combined with contralateral access to the anterior mediastinum is technically reliable and provides favorable surgical outcomes for patients with bilateral SP who develop bilateral apical bullae. However, among other requirements, this surgical procedure demands that surgeons be experienced in VATS and that the appropriate thoracoscopic instruments are available.
