Objective To systematically evaluate the efficacy and safety of traditional Chinese medicine (TCM) compound in treating pulmonary nodules, providing evidence-based medical evidence for TCM intervention in pulmonary nodules. Methods Computer search of PubMed, CNKI, Wanfang, VIP, and SinoMed was conducted to select randomized controlled trials (RCTs) of TCM compound intervention in pulmonary nodules, with the retrieval time from the inception to November 29, 2023. The Cochrane bias risk assessment tool was used to evaluate the quality of the included studies, and Review Manager 5.4 was used for Meta-analysis. Results A total of 18 RCTs were included, covering 8 provinces across the country, with a total sample size of 1301 patients. The TCM compounds used in the included studies all incorporated the method of dissolving phlegm and dissipating nodules. There was a high risk of bias uncertainty in the included studies. Meta-analysis results suggested that TCM compound could significantly reduce the diameter of pulmonary nodules [MD=−1.41, 95%CI (−1.70, −1.13), P<0.001], decrease the number of nodules [MD=−0.37, 95%CI (−0.73, −0.01), P=0.05], alleviate clinical symptoms [MD=−4.84, 95%CI (−6.04, −3.64), P<0.001], and improve lung function [forced expiratory volume in one second (FEV1), MD=0.55, 95%CI (0.09, 1.01), P=0.02; FEV1/forced vital capacity, MD=6.12, 95%CI (4.47, 7.78), P<0.001]. However, there was no statistically significant difference in the probability of malignancy between the experimental group and the control group [MD=−0.01, 95%CI (−0.01, 0.00), P=0.09]. Conclusion TCM compound can significantly reduce the diameter of pulmonary nodules, decrease the number of nodules, alleviate clinical symptoms, and improve lung function, but future multicenter, large-sample, high-quality RCTs are still needed to further explore and verify this conclusion.

Objective To explore the barriers of implementing collaborative chronic wound management within medical consortium and provide references for ensuring continuous care for chronic wound patients.Methods Using purposive and snowball sampling methods,14 specialist nurses participating in chronic wound collaborative management across medical consortium in 7 provinces/municipalities(Beijing,Shanghai,Zhejiang,Sichuan,etc.)were selected for semi-structured interviews between December 2023 and January 2024.Data were analyzed via content analysis.Results Totally 4 themes and 8 subthemes were identified,including management and organizational level(the management system needs improvement;the function of medical information mutual recognition has not been fully realized),resource and technology level(there are insufficient nursing resources at the grassroots hospitals;the specialized nursing capabilities of wound nurses at grassroots hospitals need to be enhanced),patient and demand level(patients' trust is insufficient;patients' concepts are rigid),information technology and support level(the informatization construction of grassroots hospitals lags behind;the intelligence of information systems is insufficient).Conclusion Wound specialist nurses encounter various difficulties when participating in the coordinated management of chronic wounds within the medical consortium.The management and organizational system constraints hinder the effectiveness of the nursing coordination;the resource and technology gap affects the implementation of graded wound care in the region;the lack of patient trust and misconceptions intensify the resistance to coordination;the lagging in information technology construction limits the innovative development of nursing coordination.

In this work,a fluorescent probe PIN was synthesized using indole-3-carbohydrazide and pyrenecarboxaldehyde as raw materials.PIN showed weak fluorescence emission in aqueous solution with acetonitrile volume fraction of 70％.However,when Cu2+was added to this aqueous solution of PIN,a new fluorescence emission peak appeared at 495 nm,and the intensity of this peak gradually increased with the increase of concentration of Cu2+,and also caused a significant change in the fluorescence color of the solution.In contrast,the addition of 15 kinds of other common metal ions did not cause such change.The detection limit of PIN for Cu2+was 78.7 nmol/L,which was much lower than the maximum permitting level of Cu2+in drinking water in hygienic standard for drinking water in China.Therefore,PIN was a highly selective and sensitive fluorescence-enhanced probe for Cu2+.Meanwhile,the addition of Cu2+could also cause a new absorption peak at 440 nm in the ultraviolet-visible absorption spectrum of the aqueous solution of PIN,and meanwhile the colorless PIN solution changed into yellow,exhibiting the performance of PIN as a colorimetric probe for Cu2+.By fitting with the Levenberg-Marquardt algorithm equation,the binding ratio of PIN to Cu2+was 2:1,and the binding constant was 3.42×1012 L2/mol2.In addition,the binding mode of PIN with Cu2+was explored by using proton nuclear magnetic resonance(1H NMR)titration experiments and density functional theory simulations.The results showed that the addition of Cu2+could cause the aggregation of PIN molecules to form excimers,thus showing highly selective recognition.Finally,PIN was made into a simple test strip,which could achieve rapid and convenient fluorescence detection of Cu2+in actual water samples.

Objective:To investigate clinicopathologic characteristics and molecular genetic profiles of embryonal rhabdomyosarcoma (ERMS) of the middle ear.Methods:A total of 11 cases of primary middle ear ERMS diagnosed and treated at the Fudan University Affiliated Eye and ENT Hospital between January 2016 and June 2024 were collected. Their clinicopathologic features, immunophenotypes, and molecular genetic alterations were analyzed. Relevant literature was reviewed.Results:There were 8 male and 3 female children. The mean age was 6 years, median age, 6 (5, 7) years, with a range of 1 to 11 years. Clinical manifestations included otorrhea, ear pain, ear fullness, tinnitus, and hearing loss, with some patients also presenting with facial paralysis, hoarseness, and choking on drinking. Otoscopic examination revealed granulomatous neoplasms in the external auditory canal. Imaging studies showed irregular soft-tissue masses in the middle ear region, accompanied by bony destruction and invasion of adjacent structures. Histologically, 10 of the tumors were composed of primitive small round cells, stellate cells, and short spindle-shaped cells, with an alternating loose and dense distribution pattern, and varying degrees of rhabdomyoblastic differentiation in some areas. One tumor exhibited the classic botryoid subtype morphology. Immunohistochemistry supported the diagnosis of rhabdomyosarcoma, and the Ki-67 proliferation index ranged from 40% to 80%. Next-generation sequencing (DNA-seq) was performed on 9 cases, revealing copy number variations of chromosome 7 in 4 cases, PDE4DIP mutations in 5 cases, and C19orf69::TPM3 gene fusions in 6 cases. HPV PCR testing showed HPV11 positivity in 2 cases. All 11 patients underwent surgical treatment, with 4 patients receiving adjuvant chemoradiotherapy. Follow-up until February 2025 revealed 8 deaths, among which 4 cases harbored both C19orf69::TPM3 fusions and PDE4DIP mutations and one had C19orf69::TPM3 fusions alone.Conclusions:ERMS of the middle ear is a rare type of malignant tumor with a relatively poor prognosis. Our study indicates that the concurrence of PDE4DIP mutation and C19orf69::TPM3 gene fusion may indicate poor prognosis in middle ear EMRS, providing a potential target for subsequent individualized treatment.

Spine fracture and dislocation are common traumatic spinal conditions that often require surgical intervention due to compromised spinal stability. Surgical approaches include anterior, posterior, and combined anterior-posterior spinal procedures. According to the specific surgical requirements, patients may be placed in the prone position or repositioned between prone and supine positions during surgery. Intraoperative repositioning has become an essential step in patient positioning. However, during repositioning, patients with spinal fracture and dislocation are at increased risk for complications such as hemodynamic instability, nerve injury, and pressure injuries to the skin and soft tissue. Notably, due to the instability of the spinal cord, even minor manipulations can further exacerbate the damage, potentially leading to severe outcomes like paraplegia. Although the current clinical guidelines provide instructive recommendations for standard position, there remains no specific protocols for intraoperative repositioning in patients with spine fracture and dislocation. With a concern for the lack of clinical studies on positioning techniques, risk prevention, and operational norms for special patients, no applicable guidelines or standards are available. A consensus was required to provide clinical reference, meet the requirements of surgical treatment, and minimize the safety risks of patients caused by improper placement of positions. Professional Committee of Operating Room Nursing of Shaanxi Nursing Association organized experts in nursing management and operating room nursing from major hospitals across China to formulate Expert consensus on intraoperative repositioning for patients with spinal fracture and dislocation ( version 2025). The consensus provides 11 recommendations covering pre-repositioning preparation, intraoperative maneuvers, and post-repositioning observation, aiming to provide references for clinical standardization of the intraoperative repositioning process and protection of patients′ safety.

Objective:To evaluate the efficacy and immunological mechanisms of pegylated interferon α-2b (Peg-IFNα-2b) antiviral therapy in treatment-naive patients with chronic hepatitis B(CHB).Methods:A total of 166 treatment-naive CHB patients, who were treated at Department of Infectious Diseases, the Second Affiliated Hospital of Nanchang University from March 2021 to March 2023, were enrolled in this study. All the patients received Peg-IFNα-2b therapy for 48 weeks. Serum hepatitis B virus (HBV) DNA, HBV serological markers, biochemical parameters, peripheral blood lymphocyte subsets and serum cytokine levels were detected and compared before and after treatment. Chi-square test, Mann-Whitney U test and paired sample t test were used for statistical comparison. Multivariate logistic regression analysis was used to analyze the influencing factors of hepatitis B surface antigen (HBsAg) seroconversion by stepwise regression method, and the receiver operator characteristic curve (ROC curve) was used to evaluate the predictive efficacy of immune indicators on HBsAg seroconversion. Results:Among the 166 treatment-naive CHB patients, the rate of HBV DNA negativity following 48 weeks of Peg-IFNα-2b therapy was 71.08%(118/166), the rate of hepatitis B e antigen (HBeAg) negativity was 32.05%(25/78), and the rate of HBsAg negativity was 20.48%(34/166). HBsAg negativity rate was 52.17%(24/46) in patients with baseline HBsAg<200 IU/mL, 10.26%(4/39) in patients with baseline HBsAg 200 to <1 200 IU/mL, and 7.41%(6/81) in patients with baseline HBsAg≥1 200 IU/mL, and the difference was statistically significant( χ2=39.37, P<0.001). After 48 weeks of treatment, serum levels of alanine transaminase (ALT), aspartate transaminase (AST), total bilirubin (TBil), and alpha-fetoprotein (AFP) were significantly lower than those before treatment ( Z=9.33, 8.58, 5.99, 2.36, respectively, all P<0.05). lmmune indicators were detected in 58 patients, and the proportion of peripheral blood lymphocytes increased significantly post-treatment, with notable increases in CD3 + CD8 + T/CD3 + T, CD3 + CD4 + DR + /CD3 + CD4 + , CD3 + CD8 + DR + /CD3 + CD8 + , CD3 + CD8 + CD38 + /CD3 + CD8 + , CD3 + CD8 + CD28 + /CD3 + CD8 + , and CD19 + B cells, and the differences were all statistically significant ( t=-2.56, t=-8.65, Z=-3.58, t=-3.66, Z=-3.04, t=-3.62, t=-3.87, respectively, all P<0.05). Conversely, the proportion of CD3 + , CD3 + CD4 + T/CD3 + T, CD3 + CD4 + CD45RO + /CD3 + CD4 + , CD3 + CD8 + CD45RO + /CD3 + CD8 + and the CD4 + /CD8 + ratio decreased significantly post-treatment ( t=3.13, t=5.61, t=3.69, Z=3.95, Z=7.33, respectively, all P<0.05). No significant differences were observed in the proportion of CD16 + CD56 + natural killer (NK) cells, CD3 + CD4 + CD28 + /CD3 + CD4 + , CD3 + CD4 + CD38 + /CD3 + CD4 + cells before and after treatment (all P>0.05). Serum levels of interleukin(IL)-8, IL-12P70, and IL-17 significantly decreased post-treatment ( Z=2.85, 3.26, 4.12, respectively, all P<0.05), while IL-2, IL-1β, and interferon(IFN)-α levels were significantly elevated compared to baseline ( Z=-4.92, -4.85, -9.01, respectively, all P<0.001). There were no significant differences in IL-4, IL-6, and IL-10 levels before and after treatment (all P>0.05). Logistic regression analysis identified CD3 + CD8 + T/CD3 + T(odd ratios ( OR)=1.198, 95%confidence interval( CI) 1.003 to 1.432, P=0.046), CD3 + CD4 + DR + /CD3 + CD4 + ( OR=1.185, 95% CI 1.035 to 1.357, P=0.014), CD3 + CD8 + DR + /CD3 + CD8 + ( OR=0.813, 95% CI 0.690 to 0.958, P=0.013), CD3 + CD4 + CD38 + /CD3 + CD4 + ( OR=0.678, 95% CI 0.488 to 0.940, P=0.020), CD3 + CD8 + CD38 + /CD3 + CD8 + ( OR=1.272, 95% CI 1.069 to 1.512, P=0.007), CD19 + B cells( OR=0.752, 95% CI 0.582 to 0.971, P=0.029), IL-2( OR=8.568, 95% CI 1.927 to 38.087, P=0.005), and IL-17( OR=0.728, 95% CI 0.535 to 0.989, P=0.042) as independent factors influencing HBsAg seroconversion. The area under the curve (AUC) of the proportion of dCD19 + B cells (the reciprocal of CD19 + B cells) for predicting HBsAg seroconversion was 0.716, the sensitivity was 0.636, and the specificity was 0.809. The AUC of IL-2 was 0.657, the sensitivity was 0.818, and the specificity was 0.404. The AUC of dIL-17 (the reciprocal of IL-17 levels) was 0.624, the sensitivity was 0.727, and the specificity was 0.489. The AUC of IL-2 and dIL-17 as a combined predictor was 0.830, the sensitivity was 0.909, and the specificity was 0.787. Conclusions:Peg-IFNα-2b demonstrates significant antiviral, biochemical, and serological responses in treatment-naive CHB patients, with enhanced efficacy in patients exhibiting HBsAg levels <200 IU/mL. In patients with HBsAg<200 IU/mL, the rate of HBsAg negativity reached 52.17%.Peg-IFNα-2b can regulate the immune function of patients with CHB by increasing the proportion of activated T lymphocyte subsets and functional subsets. The proportion of CD19 + B cells, IL-2 levels, and IL-17 levels hold predictive value for achieving HBsAg seroconversion.

Objective:To investigate the efficacy and potential mechanism of sulfasalazine (SASP) therapy for intrahepatic cholestasis.Methods:Forty SD rats were randomly divided into a normal group (carboxymethylcellulose sodium 0.5%), a model group (carboxymethylcellulose sodium 0.5%), a SASP group (sulfasalazine 150 mg/kg), and an ursodeoxycholic acid (UDCA 100 mg/kg) group, with ten rats in each group. The cholestatic liver injury model was induced using α-naphthylisothiocyanate. Blood samples were collected to detect liver biochemistry and cholestasis indexes. Rat liver tissue was collected for hematoxylin-eosin staining and Mason staining. Liver tissue was analyzed using transcriptome sequencing, real-time reverse transcription quantitative polymerase chain reaction, Western blotting and flow cytometry. Simultaneously, the level of inflammatory factors, total cholesterol, and total bile acids were measured in liver tissue. A t-test or a nonparametric test was selected based on the distribution and variance characteristics of the data. Results:The serum levels of alanine aminotransferase [(386.88±155.77) U/L], aspartate aminotransferase [(593.13±251.44) U/L], alkaline phosphatase [(561.25±167.54) U/L], total bilirubin [(38.00±29.75) mol/L] and total bile acids [(191.31±91.48) mol/L] were significantly lower in the SASP than the model groups [(778.75±313.59) U/L, (1 159.38±274.62) U/L, (801.25±161.28) U/L, (86.63±27.83) mol/L, (432.63±151.54) mol/L, P<0.05]. Liver histopathology showed that the inflammatory cells in the manifold area, the bile duct proliferation and dilation, and the collagen deposition in the manifold area were significantly improved under the pathological state of cholestasis in the SASP group. The results of transcriptome sequencing demonstrated that SASP activated the peroxisome proliferator actived receptor α (PPAR α) and inhibited Th17 cell differentiation. The PPARα mRNA level in the liver tissue of rats was significantly increased in the SASP group compared with that in the model group [(0.41±0.28) vs. (0.16±0.04), P<0.05], and the expression of 3-hydroxy-3-methylglutaryl coenzyme A reductase was decreased compared with that in the model group [(3.09±1.16) vs. (8.19±2.19), P<0.05], which was also verified at the protein level. The concentrations of total cholesterol [(0.31±0.34) mmol/g] and total bile acids [(2.58±0.99) μmol/g] were lower than the model group [(0.83±0.62) mmol/g and (4.07±0.91) μmol/g] ( P<0.05), and at the same time it was accompanied by lower levels of inflammatory factors ( P<0.05). SASP treatment decreased the expression of retinoic acid receptor-related orphan receptor γt gene ( P<0.05) and the proportion of Th17 ( P<0.05). Conclusion:SASP can improve cholestatic liver injury, and its mechanism is related to the activation of peroxisome proliferator-activated receptor α and the inhibition of Th17 cell differentiation.
