Objective To investigate the clinical prognostic value of the prognostic nutritional index (PNI) in patients with renal cell carcinoma (RCC) undergoing partial nephrectomy.Methods A retrospective analysis was conducted on the clinical data of RCC patients who underwent partial nephrectomy at our hospital during 2020 and 2024.The optimal cutoff value of PNI was determined based on the maximum Youden index from the receiver operating characteristic (ROC) curve.The clinicopathological characteristics, overall survival (OS), and progression-free survival (PFS) between patients with different PNI levels were compared.Cox regression analysis was used to explore the independent prognostic factors for RCC patients. Results Based on the ROC curve, the optimal cutoff value corresponding to the maximum Youden index was calculated to be 46.675, at which point the sensitivity was 65.3% and the specificity was 62.2%.Of the 815 patients included in the study, 293 (36.0%) patients had a PNI＜46.675.Cox regression analysis confirmed that preoperative PNI, tumor diameter, ISUP classification, and ECOG score were independent risk factors for postoperative OS in patients with RCC who underwent PN (P＜0.05).In addition, preoperative PNI, tumor diameter, ISUP classification and ECOG score were independent risk factors for postoperative PFS (P＜0.05).After covariates in the multivariable Cox regression model were adjusted, patients in the low PNI group demonstrated significantly shorter overall survival (HR=2.392, P＜0.001) and significantly poorer progression-free survival (HR=2.076, P＜0.001) compared to those in the high PNI group.Conclusion Preoperative PNI has significant clinical value in evaluating the prognosis of RCC patients undergoing partial nephrectomy.An elevated preoperative PNI is associated with a better prognosis.

Objective To systematically evaluate the effects of total intravenous anesthesia and inhalational anesthesia on postoperative recovery in patients undergoing transsphenoidal pituitary tumor resection.Methods A comprehensive search was conducted in international biomedical databases including Ovid Medline,Embase,CINAHL(EBSCO),Cochrane Library,and Web of Science,from inception to July 4,2023.Additionally,ClinicalTrials.gov and the World Health Organization International Clinical Trials Registry Platform were searched for ongoing and completed trials.The randomized controlled trials(RCT)comparing total intravenous anesthesia and inhalational anesthesia in patients undergoing transsphenoidal surgery for pituitary tumors were included.The methodological quality of the included studies was evaluated by the Cochrane Collaboration tool.Relevant data were extracted and synthesized for analysis.Results A total of 327 records were identified,of which eight RCTs met the inclusion criteria.Four studies showed that the patients receiving desflurane or sevoflurane anesthesia experienced faster emergence from anesthesia than those receiving propofol.Two studies indicated that patients in the propofol group had lower levels of emergence agitation and a lower incidence of early postoperative nausea and vomiting.The results on postoperative cognitive function were inconsistent across studies.No differences were found between the groups in terms of postoperative complications or overall recovery quality during hospitalization.Conclusions Inhalational anesthesia appears to provide an advantage in promoting faster emergence following transsphenoidal pituitary surgery,whereas total intravenous anesthesia may contribute to smoother and more stable recovery.Further high-quality studies are needed to clarify the effects of different anesthetic techniques on both short- and long-term postoperative recovery.

Purpose To investigate the clinicopathological features,differential diagnosis,and prognosis of breast carcinoma within fibroadenoma(FA).Methods A retrospective analysis was performed on the clinical and imaging data of 21 cases of FA-associated carcinoma.HE staining,immunohistochemistry using the EnVision method,and next-generation sequencing were employed to assess the clinicopathological characteristics and genetic alterations,with a review of the relevant literature.Results All patients were female,aged 21-67 years,with a median age of 48 years.Clinically,all lesions presented with well-circumscribed mass lesions.On imaging,12 cases demonstrated punctate or coarse calcifications,while 3 cases exhibited locally indistinct margins.Pathological examination revealed that the tumors had an average maximum diameter of 2.25 cm,with a gray-white nodular cut surface resembling FA.Microscopically,there was proliferation of either epithelial or spindle cells.The pathological diagnosis was FA-associat-ed in situ carcinoma in 16 cases(15 cases of low-grade ductal carcinoma in situ and 1 case of lobular carcinoma in si-tu),and invasive carcinoma in 5 cases(comprising 2 cases of invasive carcinoma-no special type,1 case of invasive lobular carcinoma,1 case of low-grade adenosquamous carcinoma and 1 case of fibromatosis-like metaplastic carcino-ma).In 18 cases,the carcinoma was confined within the FA,whereas in 3 cases the tumor locally extended beyond the FA,and 1 case exhibited ipsilateral axillary lymph node metastasis.Immunophenotypically,tumor cells in in situ carcinomas were negative for CK5/6,while the myoepithelial cells were p63-positive,and both estrogen receptor(ER)and progesterone receptor(PR)were diffusely and consistently positive.In invasive carcinoma,both ductal and lobular subtypes were ER and PR positive and HER2 negative.Conversely,in the low-grade adenosquamous carcinoma and fi-bromatosis-like metaplastic carcinoma,ER,PR,and HER2 were all negative,with p63 and CK5/6 positivity.Two ca-ses were negative for mismatch repair protein PMS2.Six cases had a family or personal history of malignant tumors;a-mong the 5 cases that underwent next-generation sequencing,2 cases harbored germline BRCA2 mutations,2 cases had germline PMS2 mutations,and 1 case exhibited no definitive genetic alteration.Conclusion Carcinoma arising within FA exhibits atypical clinical and imaging features.In patients with high-risk factors for breast cancer or family history of malignancy,or when calcifications are observed on imaging,prompt excision and biopsy are recommended.Recogniz-ing the abnormal morphology within FA and the use of immunohistochemistry are essential for accurate diagnosis,with careful differentiation from spindle cell metaplastic carcinoma and low-grade adenosquamous carcinoma.Overall,the prognosis is relatively favorable,and treatment should be tailored according to tumor type,molecular subtype,and stage.

Patients suffering from nerve injury often experience exacerbated pain responses and complain of memory deficits. The dorsal hippocampus (dHPC), a well-defined region responsible for learning and memory, displays maladaptive plasticity upon injury, which is assumed to underlie pain hypersensitivity and cognitive deficits. However, much attention has thus far been paid to intracellular mechanisms of plasticity rather than extracellular alterations that might trigger and facilitate intracellular changes. Emerging evidence has shown that nerve injury alters the microarchitecture of the extracellular matrix (ECM) and decreases ECM rigidity in the dHPC. Despite this, it remains elusive which element of the ECM in the dHPC is affected and how it contributes to neuropathic pain and comorbid cognitive deficits. Laminin, a key element of the ECM, consists of α-, β-, and γ-chains and has been implicated in several pathophysiological processes. Here, we showed that peripheral nerve injury downregulates laminin β1 (LAMB1) in the dHPC. Silencing of hippocampal LAMB1 exacerbates pain sensitivity and induces cognitive dysfunction. Further mechanistic analysis revealed that loss of hippocampal LAMB1 causes dysregulated Src/NR2A signaling cascades via interaction with integrin β1, leading to decreased Ca²⁺ levels in pyramidal neurons, which in turn orchestrates structural and functional plasticity and eventually results in exaggerated pain responses and cognitive deficits. In this study, we shed new light on the functional capability of hippocampal ECM LAMB1 in the modulation of neuropathic pain and comorbid cognitive deficits, and reveal a mechanism that conveys extracellular alterations to intracellular plasticity. Moreover, we identified hippocampal LAMB1/integrin β1 signaling as a potential therapeutic target for the treatment of neuropathic pain and related memory loss.

Functional dyspepsia (FD), characterized by persistent or recurrent dyspeptic symptoms without identifiable organic, systemic or metabolic causes, is an increasingly recognized global health issue. The objective of this guideline is to equip clinicians and nursing professionals with evidence-based strategies for the management and treatment of adult patients with FD using traditional Chinese medicine (TCM). The Guideline Development Group consulted existing TCM consensus documents on FD and convened a panel of 35 clinicians to generate initial clinical queries. To address these queries, a systematic literature search was conducted across PubMed, EMBASE, the Cochrane Library, China National Knowledge Infrastructure (CNKI), VIP Database, China Biology Medicine (SinoMed) Database, Wanfang Database, Traditional Medicine Research Data Expanded (TMRDE), and the Traditional Chinese Medical Literature Analysis and Retrieval System (TCMLARS). The evidence from the literature was critically appraised using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach. The strength of the recommendations was ascertained through a consensus-building process involving TCM and allopathic medicine experts, methodologists, pharmacologists, nursing specialists, and health economists, leveraging their collective expertise and empirical knowledge. The guideline comprises a total of 43 evidence-informed recommendations that span a range of clinical aspects, including the pathogenesis according to TCM, diagnostic approaches, therapeutic interventions, efficacy assessments, and prognostic considerations.

Objective:To investigate the effect of physical activity on mortality risk in patients with chronic obstructive pulmonary disease (COPD) in Sichuan Province.Methods:Based on baseline data from 2004 to 2008 from the China Kadoorie Biobank project site in Pengzhou City, Sichuan Province, a total of 8 501 COPD patients aged 30-79 years were enrolled and followed up for a long period to determine mortality outcomes. Quartiles were used to group physical activity levels. The Cox proportional hazards regression model was used to analyze the effect of physical activity level on mortality outcomes.Results:As of December 31, 2017, the cumulative follow-up of the participants totaled 85 600.58 person-years (mean follow-up duration: 10.07 years). During this period, a total of 2 000 deaths were recorded, yielding a cumulative mortality rate of 23.53%. Among these deaths, 665 were attributed to COPD, corresponding to a cumulative mortality rate of 7.82%; and 1 116 were attributed to cardiovascular and cerebrovascular disease (CVD), corresponding to a cumulative mortality rate of 13.13%. The Cox proportional hazards regression model analysis revealed that, after adjusting for confounding factors, total physical activity was associated with a reduced risk of mortality from COPD, CVD, and all causes in patients with COPD. Compared with the low-level group of total physical activity, the medium-high-level group had the lowest risk of COPD mortality, with an HR of 0.39 (95% CI: 0.30-0.49). The high-level group had the lowest risk of CVD death and all-cause death, with HRs of 0.46 (95% CI: 0.37-0.56) and 0.55 (95% CI: 0.48-0.64), respectively. The lowest risk of COPD death and CVD death was found in the medium-high level of work-based physical activity group, with HRs of 0.36 (95% CI: 0.28-0.46) and 0.43 (95% CI: 0.36-0.51), respectively; the risk of all-cause mortality was lowest in the medium-high and high-level groups, with HRs values of 0.53 (95% CI: 0.46-0.61) and 0.53 (95% CI: 0.45-0.61). The risk of COPD death was lowest in the high-level transportation physical activity group, with an HR of 0.66 (95% CI: 0.53-0.83), and the risk of CVD and all-cause death was lowest in the medium-high level group, with HRs of 0.63 (95% CI: 0.53-0.76) and 0.73 (95% CI: 0.64-0.84), respectively. The risk of COPD death and CVD death was the lowest in the high-level domestic physical activity group, with HRs of 0.66 (95% CI: 0.49-0.89) and 0.76 (95% CI: 0.61-0.95), respectively, and the risk of all-cause death was the lowest in the medium-high level group, with an HR of 0.82 (95% CI: 0.72-0.94). There is no statistical association between leisure physical activity and the risk of death from three types of diseases. Conclusions:Total physical activity, including work-based, transportation-based, and domestic physical activity, reduced the risk of COPD, CVD, and all-cause mortality in patients with COPD in Sichuan Province. The magnitude of mortality risk was influenced by the type and level of physical activity.

Objective To analyze the molecular epidemiological characteristics of carbapenem-resistant Klebsiella pneumoniae(CRKP)in a hospital in Hainan Province,explore the differences in the distribution of resistance genes and virulence factors between hypervirulent CRKP(hv-CRKP)and non-hv-CRKP,analyze the clinical significance,and provide basis for optimizing treatment and prevention strategies.Methods CRKP strains isolated from a hospi-tal in Hainan Province from July 2023 to June 2024 were collected retrospectively.Their resistance phenotypes were detected by antimicrobial susceptibility testing.Carbapenemase genes(KPC-2,NDM-1,IPM)and virulence factors(rmpA/rmpA2,iucA,iroB,etc.)were detected by polymerase chain reaction(PCR).Department source,speci-men distribution,and resistance-virulence characteristics were analyzed.Results A total of 76 strains of CRKP were isolated,with an overall isolation rate of 7.7％(76/985).The strains were mainly distributed in the intensive care unit(ICU)(28.9％)and neurosurgery ICU(23.6％),with the highest proportion of strains isolated from re-spiratory tract specimens(60.5％).The resistance genes were mainly KPC-2(72.4％)and NDM-1(21.1％),and the virulence factors mrkD(type Ⅲ pili,85.5％)and fim H(type Ⅰ pili,84.2％)were commonly presented.Among 76 strains of CRKP,39 strains(51.3％)met the criteria for hv-CRKP and all carried KPC-2 gene(100％).The detection rates of resistance genes and virulence factors rmpA2(97.4％),iucA(100％),and iroB(89.7％)were all higher than those of non-hv-CRKP strains(KPC-2,43.2％;rmpA2,0;iucA,8.1％;iroB,13.5％).The main characteristics of hv-CRKP was the combination of KPC-2 resistance gene and rmpA2+iucA+iutA+iroB virulence factors(64.1％).Antimicrobial resistance phenotype of hv-CRKP was different from non-hv-CRKP.hv-CRKP presented higher susceptibility rates to aminoglycosides and compound sulfamethoxazole than non-hv-CRKP.Conclusion The proportion of hv-CRKP and non-hv-CRKP strains in this hospital is comparable.hv-CRKP is characterized by carrying the KPC-2 resistance gene in combination with rmpA2+iucA+iutA+iroB virulence factors,and the proportion of strains carrying multiple virulence factors is higher than that of non-hv-CRKP.Both are generally resistant to β-lactams and quinolones.hv-CRKP has lower resistance rates to aminoglycosides and com-pound sulfamethoxazole than non-hv-CRKP.Its advantage of aminoglycoside susceptibility provides a new treatment option.It is recommended to guide differential medication through molecular typing and strengthen infection control measures in ICU to curb the spread of antimicrobial-resistant bacteria.

Objective To investigate the value of the combined detection of neutrophil CD64(nCD64),C-reactive protein(CRP)and lactate dehydrogenase(LDH)in the diagnosis of refractory Mycoplasma pneumoniae pneumonia(RMPP)in children.Methods A total of 147 children with Mycoplasma pneumoniae infection were enrolled and divided into the RMPP group(n=70)and the general Mycoplasma pneumoniae pneumonia group(GMPP,n=77)based on disease severity and treatment response.The age,gender,white blood cell count(WBC)within 24 hours of admission,serum procalcitonin(PCT),C-reactive protein(CRP)and lactate dehydrogenase(LDH)levels were collected in the study participants.The expression level of nCD64 in peripheral blood was measured using flow cytometry.Multivariate Logistic regression analysis was conducted to identify the independent risk factors associated with RMPP in children.Additionally,a receiver operating characteristic(ROC)curve was constructed to assess the diagnostic performance of the combined detection of nCD64,CRP and LDH for RMPP in children.Results The RMPP group had a longer hospital stay than the GMPP group(P＜0.05).Levels of nCD64,CRP and LDH were significantly higher in the RMPP group compared to those of the GMPP group(P＜0.05),and there were no significant differences in WBC and PCT levels between the two groups.Multivariate Logistic regression analysis showed that elevated nCD64,CRP and LDH were risk factors for RMPP in children(P＜0.05).ROC curve analysis revealed that the areas under the curve(AUC)for nCD64,CRP and LDH in diagnosing RMPP were 0.817,0.863 and 0.805,respectively.The combined detection of three indicators for AUC was 0.948.Conclusion The levels of nCD64,CRP and LDH in blood of children with RMPP are higher than those of children with GMPP.The combined detection of the three indicators has a high diagnostic value for RMPP in children with Mycoplasma pneumoniae pneumonia.
