ObjectiveTo evaluate the clinical efficacy and safety of acupuncture combined with levodopa in the treatment of Parkinson's disease（PD）. MethodsA total of 60 patients with PD were enrolled and randomly assigned to test group or control group， with 30 patients in each group. The control group received levodopa only， starting at 100 mg per dose， three times daily， with gradual increases not exceeding a maximum daily dose of 800 mg. The test group received acupuncture three times per week in addition to levodopa. Both groups were treated for 12 weeks. Assessments were conducted before treatment， after 6 and 12 weeks treatment， using the Unified Parkinson's Disease Rating Scale（UPDRS）， Wearing-Off Questionnaire-9（WOQ-9）， Montreal Cognitive Assessment（MoCA）， Mini-Mental State Examination（MMSE）， Depression Rating Scale（DRS）， Hamilton Depression Scale（HAMD）， Hamilton Anxiety Scale（HAMA）， PD Questionnaire-39（PDQ-39）， and Pittsburgh Sleep Quality Index（PSQI）. Repeated measures ANOVA was utilized to evaluate the effects of time， group， and their interaction on each index. Spearman correlation analysis was conducted to examine the relationships between combined treatment and outcome scores. Adverse events in both groups were recorded throughout the study. ResultsBoth groups showed significant improvements after 6 and 12 weeks treatment， with decreases in UPDRS total score， WOQ-9 total score， DRS score， HAMD score， HAMA score， PDQ-39 score， and PSQI score， and increases in MoCA and MMSE scores（P＜0.05）. Compared with the control group， the test group demonstrated significantly greater improvements in all the above indicators after 6 and 12 weeks （P＜0.05）. Repeated measures ANOVA showed significant time main effects， group main effects， and their interaction across all outcome measures（P＜0.01）. Spearman correlation analysis revealed that combined therapy was significantly negatively correlated with UPDRS， WOQ-9， DRS， HAMD， HAMA， PDQ-39， and PSQI scores， while positively correlated with MoCA and MMSE scores after 12 weeks of treatment（P＜0.05）. Both groups did not experience any serious adverse events and did not affect treatment. ConclusionAcupuncture combined with levodopa is more effective than levodopa alone in improving motor function， non-motor symptoms， cognitive function， depression and anxiety， quality of life， and sleep quality in patients with PD， with good safety.

OBJECTIVE To explore the efficacy and safety of ruxolitinib in the treatment of myelofibrosis （MF）. METHODS A retrospective collection of data was conducted on 42 MF patients who were treated with ruxolitinib in a standardized manner for more than 6 months in the Third People’s Hospital of Bengbu from September 2018 to April 2024. The clinical symptom scores， spleen size reduction， and MF grading of the patients before and after treatment were analyzed. Additionally， the occurrence of adverse reactions with a causality assessment result of “definite”“probable” or “possible” was recorded. The patients’ survival status was followed up. RESULTS After 6 months of treatment， both clinical symptom scores and the total score were significantly decreased than before treatment （P＜0.05）. The length and thickness of the spleen were significantly shorter than before treatment （P＜0.05）. MF classification in 5 patients decreased by 1 level compared with baseline， 1 case was level 2 and dropped to level 0， 14 patients remained stable. The main adverse reactions were anemia （26 cases）， thrombocytopenia （14 cases）， infection （11 cases）， and gastrointestinal discomfort （9 cases）. Thirty-nine patients survived， with a survival rate of 92.86%. CONCLUSIONS Ruxolitinib can effectively improve the clinical symptoms of patients with MF， shrink the spleen， stabilize and even improve MF grading， and holds promise for bringing long-term survival benefits to MF patients. Adverse reactions are mainly anemia， thrombocytopenia， infection and gastrointestinal discomfort.

Astrocytes in the spinal dorsal horn (SDH) exhibit diverse reactive phenotypes under neuropathic conditions, yet the mechanisms driving this diversity and its implications in chronic pain remain unclear. Here, we report that spared nerve injury (SNI) induces marked upregulation of both complement component 3 (C3⁺, A1-like) and S100 calcium-binding protein A10 (S100A10⁺, A2-like) astrocyte subpopulations in the SDH, with elevated microglial cytokines including interleukin-1α, tumor necrosis factor-α, and complement component 1q. Transcriptomic, immunohistochemical, and Western blot analyses reveal co-activation of multiple reactive astrocyte states over a unidirectional shift toward an A1-like phenotype. Fibroblast growth factor 8 (FGF8), a neuroprotective factor via FGFR3, mitigated microglia-induced C3⁺ astrocyte reactivity in vitro and suppressed spinal C3 expression and mechanical allodynia following intrathecal administration in SNI mice. These findings reveal a microglia-astrocyte signaling axis that promotes A1 reactivity and position FGF8 as a promising therapeutic candidate for neuropathic pain by modulating astrocyte heterogeneity.

ObjectiveTo investigate the safety and feasibility of intra-biliary drainage tube placement after laparoscopic common bile duct exploration in elderly patients with choledocholithiasis， and to provide more options for surgical procedures in the clinical management of elderly patients with choledocholithiasis. MethodsA retrospective analysis was performed for the clinical data of 52 elderly patients with choledocholithiasis who were admitted to Department of Hepatobiliary Surgery， Affiliated Dalian Friendship Hospital of Dalian Medical University， from November 2021 to October 2024. According to the biliary drainage method after surgery， the patients were divided into internal drainage group with 24 patients and T-tube drainage group with 28 patients， and there were 19 patients in each group after propensity score matching. The two groups were compared in terms of perioperative parameters and postoperative complications. The Wilcoxon rank-sum test was used for comparison of continuous data between two groups， and the chi-square test or the Fisher’s exact test was used for comparison of categorical data between two groups. ResultsCompared with the T-tube drainage group， the internal drainage group had a significantly shorter length of postoperative hospital stay and a significantly lower volume of postoperative bile loss （Z=-2.845 and -5.633， both P<0.05）， while there were no significant differences between the two groups in time of operation， intraoperative blood loss， and drainage tube indwelling time （all P>0.05）. There were no significant differences between the two groups in postoperative bile leak， stone recurrence， biliary stricture， and drainage tube-related complications， and the internal drainage group had a significantly lower total complication rate than the T-tube drainage group ［1 （5.3%） vs 7 （36.8%）， P<0.05］. ConclusionFor elderly patients with choledocholithiasis， intra-biliary drainage tube placement after laparoscopic common bile duct exploration can shorten the length of postoperative hospital stay， reduce bile loss， and lower the incidence rate of postoperative complications， thereby helping to accelerate postoperative recovery.

Objective: To translate the Maternal Blue Scale (MBS) into Chinese, and evaluate the reliability and validity. Methods: The MBS was translated back-translated, culturally adapted and pre-tested according to the Brislin translation model to develop the Chinese version of MBS. Postpartum women from obstetrics centers in three tertiary general hospitals in Shandong Province were selected using convenience sampling method to assess the reliability and validity of the Chinese version of MBS. Content validity was evaluated based on expert ratings. Criterion-related validity was evaluated using the Chinese version of the Edinburgh Postnatal Depression Scale (EPDS) as the criterion. Structural validity was evaluated using exploratory and confirmatory factor analyses. Reliability was assessed by calculating Cronbach's α and split-half reliability. Receiver operating characteristic (ROC) curve was plotted to evaluate predictive validity. Results: Totally 500 questionnaires were allocated, and 479 valid ones were recovered, with an effective recovery rate of 95.80%. The Chinese version of MBS consisted of 32 items across 6 dimensions: mother-infant communication, infant feeding, role adaptation, maternal responsibilities, family acceptance and social support. The item-level content validity index ranged from 0.900 to 1.000, and the scale-level content validity index/average was 0.990. The correlation coefficient between the Chinese version of MBS scores and the Chinese version of EPDS scores was 0.675 (P<0.05). Exploratory factor analysis extracted 6 common factors, with a cumulative variance contribution rate of 74.581%. Confirmatory factor analysis indicated good model fit, with a root mean square error of approximation of 0.014, a goodness of fit index of 0.896, a comparative fit index of 0.996, an incremental fit index of 0.996, a normed fit index of 0.913, and a Tucker-Lewis index of 0.995. The overall Cronbach's α was 0.924, and the split-half reliability was 0.765. The Cronbach's α of each dimension ranged from 0.809 to 0.956, and the split-half reliability ranged from 0.807 to 0.966. The area under the ROC curve was 0.909 (95%CI: 0.880-0.937). At the optimal cutoff score of 75.5, the Youden index reached its maximum of 0.698, with a sensitivity of 0.874 and a specificity of 0.824. Conclusion The Chinese version of MBS has good reliability and validity, and it is suitable to evaluate maternal blue among Chinese postpartum women.

Objective To explore the current status of posttraumatic growth (PTG) among nurses at psychiatric department and analyze its latent profiles and population characteristics. Methods A total of 357 nurses from psychiatric departments of five tertiary Grade A hospitals were selected as the research subjects using the convenience sampling method. The PTG and professional quality of life were studied using the Posttraumatic Growth Inventory and the Chinese version of the Compassion Fatigue Scale. Results The PTG score of the nurses was (56.6±23.2). The scores of compassion satisfaction, burnout, and secondary traumatic stress among nurses were (32.6±7.2), (26.9±5.9), and (26.0±5.4), respectively. The result of potential profile analysis showed that the nurses could be divided into three latent profiles based on PTG levels: low PTG group (34.4%), moderate PTG group (44.0%), and high PTG group (21.6%). The results of multinomial logistic regression analysis showed that the nurses who slept 7-8 hours per day were at higher risk of being in the high PTG group compared with those who slept more than eight hours per day (P<0.05). Psychiatric nurses who took regular exercise were at higher risk of being in the high PTG group compared with those who took irregular exercise (P<0.05). The nurses who had high job satisfaction scores were at higher risk of being in the high PTG group compared with those who had low job satisfaction scores (P<0.01). The nurses with higher compassion satisfaction scores increased the risk of being in the high PTG group compared with those with lower compassion satisfaction scores (P<0.01). The nurses with higher burnout scores increased the risk of being in the low PTG group compared with those with lower burnout scores (P<0.01). Conclusion The PTG characteristics of the nurses exhibit heterogeneity and can be categorized into three distinct profiles. Sleep duration, regular exercise, job satisfaction, compassion satisfaction, and burnout are influencing factors for the PTG latent profiles of nurses working at psychiatric department.

Objective To use superparamagnetic iron oxide nanoparticles(SPIONs)to label chimeric antigen receptor(CAR)T cells targeting carcinoembryonic antigen(CEA),and perform magnetic resonance imaging(MRI)to real time trace CEA CAR-T cells in vivo.Methods Appropriate amount of ferumoxytol,heparin sodium and protamine sulfate were mixed at high(ferumoxytol 100 μg/mL,heparin sodium 4 IU/mL,protamine sulfate 120 μg/mL),medium(ferumoxytol 50 μg/mL,heparin sodium 2 IU/mL,protamine sulfate 60 μg/mL),and low(ferumoxytol 25 μg/mL,heparin sodium 1 IU/mL,protamine sulfate 30 μg/mL)concentrations to form a SPIONs complex ferumoxytol/heparin/protamine(FHP),and then co-incubated with CEA CAR-T cells for cell labeling.The biocompatibility of FHP was detected by CCK-8 assay,EdU assay and flow cytometry.The uptake of FHP was detected by Prussian blue staining,and SPIONs content in the cells was quantitatively detected by inductively coupled plasma-mass spectrometry(ICP-MS).Flow cytometry was used to detect the lytic effect of FHP-labeled CEA CAR-T cells on tumor cells,and MRI was employed to scan FHP-labeled CEA CAR-T cells.Results FHP at high,medium,and low concentrations had no significant effect on the activity of CEA CAR-T cells,with cell activity above 100％determined by CCK-8 assay.DNA proliferation was above 94.3％in EdU assays.Prussian blue staining showed that CEA CAR-T cells could take FHP up,with the uptake increased with the increment of FHP concentration.ICP-MS showed that the intracellular Fe content was 440.23±189.36 ng/mL.Tumor cell killing experiment showed that FHP-labeled CEA CAR-T cells had excellent killing capability against tumor cells.MRI scans indicated that T2WI signals of FHP-labeled CEA CAR-T cells were significantly reduced with increasing FHP concentration(P＜0.01).Conclusion SPIONs complex FHP shows good biocompatibility and can effectively label CEA CAR-T cells.SPIONs complex FHP can be used as a magnetic marker for CEA CAR-T cells and a feasible MRI tracer for clinical application.

Objective To observe the comfort effect of gene-transfected pig skin in patients with arc burn wound.Methods A total of 56 patients with electric arc burn treated in our hospital from June 2020 to December 2022 were enrolled and then randomly divided into treatment group and control group,with 28 cases in each group.Both groups were treated with debridement,including removing pollutants and necrotic skin,and cleaning the wounds with normal saline.After debridement,the shallow second-degree burn wounds in the control group were covered with silver ion functional antibacterial dressing and wrapped with sterile cotton pad,while those in the treatment group were covered with thawed and softened gene-transfected pig skins.For the deep second-degree burn wounds,after simple debridement,the wounds were treated with scab grinding in 48 h after burn when the condition of the patients was stable.After this,the wounds in the control group and the treatment group were treated as the shallow wounds,respectively.Visual Analogue Scale(VAS),State Anxiety Inventory(SAI)score,treatment process satisfaction,patient comfort and time for wound healing were observed and compared between the 2 groups.Results There was no significant difference in the VAS score and SAI score between the 2 groups at the first dressing change(P＞0.05),but the VAS score and SAI score were obviously lower in the treatment group than the control group at the second and third dressing changes(P＜0.05).The treatment group obtained notably better comfort level and shorter time for wound healing than the control group(P＜0.05).Conclusion Gene-transfected pig skin shows good efficacy in the wound surface of arc burn,which can shorten the wound healing time,reduce the pain of dressing change and improve the satisfaction and comfort of patients.

Objective To investigate the effect of microRNA-223(miR-223)on prostate cancer cell damage by regulating the Kelch-like epichlorohydrin related protein 1(Keap1)/nuclear factor E2 related factor 2(Nrf2)/antioxidant response element(ARE)signaling pathway.Methods The prostate cancer cell line PC3 was cultured and randomly divided into control,down-regulated miR-223,and up-regulated miR-223 groups.Changes in miR-223 expression,cell proliferation rate,cell migration number,cell invasion number,apoptosis rate,and expression level of Keap1/Nrf2/ARE signaling pathway were explored.Results Compared with the control group,the cell invasion number,cell migration number,cell proliferation rate,Nrf2 and ARE expression increased at 24,48 and 72 h in down-regulated miR-223 group,while the expressions of miR-223,Keap1 and apoptosis rate decreased(P<0.05).Compared with the down-regulated miR-223 group,24,48 and 72 h cell proliferation rate,cell invasion number,cell migration number,ARE and Nrf2 expression decreased in the up-regulated miR-223 group,while miR-223,apoptosis rate and Keap1 expression increased(P<0.05).Conclusion Regulation of miR-223 effectively ameliorates prostate cell injury,and the mechanism may be related to the Keap1/Nrf2/ARE signaling pathway.
