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 evaluate the efficacy and safety of rituximab (RTX) in the treatment of idiopathic membranous nephropathy (IMN), explore the influencing factors of the therapeutic effect and construct a nomogram model for predicting the therapeutic effect.Methods:A single retrospective study was conducted in IMN patients in the First Affiliated Hospital of Zhejiang University School of Medicine from January 2017 to December 2022. All patients received monotherapy with RTX and were followed up for at least 12 months. RTX regimen adopted a B-cell guided regimen to achieve 0 cells/μl of peripheral blood CD19+ B cells through multiple administrations, followed by monitoring every 2?3 months and adding doses as needed to maintain this state. The complete response rate, partial response rate, and composite response rate at 6 months, 12 months and the end of follow up were analyzed. Logistic stepwise regression and R language were applied to construct a nomogram model for efficacy prediction. The receiver operating characteristic (ROC) curve, calibration curve and Hosmer-Lemeshow test were used to internally validate the nomogram model.Results:A total of 147 IMN patients were included in the study, with age of 56 (47, 65) years, 99 (67.4%) males. There were 69 (46.9%) newly treated patients, 78 (53.1%) retreatment patients. The follow-up time was 14.4 (12.0, 15.0) months. The total RTX dose was 1 800 (1 200, 2 400) mg. The composite response rates at 6 months, 12 months and the end of the follow-up were 36.7% (54/147), 59.9% (88/147) and 63.3% (93/147), respectively. The complete remission rates at 6 months, 12 months and the end of the follow-up were 6.1% (9/147), 13.6% (20/147) and 19.7% (29/147), respectively. Logistic stepwise regression analysis showed that age ≥ 65 years ( OR=0.335, 95% CI 0.135?0.833), retreatment ( OR=0.333, 95% CI 0.144?0.771), high cholesterol ( OR=0.716, 95% CI 0.577?0.888), high serum creatinine ( OR=0.978, 95% CI 0.963?0.993) and B-cell reconstruction within 6 months ( OR=0.273, 95% CI 0.115?0.645) were independent correlated factors affecting composite remission. Based on these factors, a nomogram model for predicting the therapeutic effect of RTX in IMN patients was constructed. The ROC curve indicated that the accuracy of this model in predicting composite remission was good ( AUC=0.814, 95% CI 0.744-0.883). The calibration curve showed that the predicted composite response rate had a good fit with the actual response rate (Hosmer-Lemeshow test χ2=11.917, P=0.155). Conclusions:RTX has good efficacy and safety as a monotherapy for IMN patients. The constructed nomogram prediction model has high discrimination and accuracy to predict the efficacy of RTX treatment for IMN.

This study aims to investigate the effects of the skin tissue derived peptides on proliferation, apoptosis, migration and collagen expressions in keloid fibroblasts. From January 2015 to January 2017, patients with hypertrophic scar who underwent surgical excision in department of plastic surgery of Nanjing maternal and child health hospital were included in this retrospective study. Four peptides were selected from the differential peptides between human hypertrophic scar and normal skin tissue. They were named as peptide deregulated in hypertrophic scar 2-5 (PDHPS2-5). Bioinformatics and functional analysis were performed. A low dose of 10 μmol/L of four peptides were respectively added to the culture medium of human primary keloid fibroblasts for 24 h. Cell counting kit-8 (CCK-8) were used to detect the changes in cell viability. Cell apoptosis was detected by flow cytometry. Cell migration ability was checked by Transwell chamber. The protein expressions of collagen COL1A2 (Collagen type I alpha 2) and the myofibroblast marker gene ACTA2 (Actin alpha 2) were analyzed by Western blot. The results showed that bioinformatics prediction analysis revealed that peptide PDHPS4 has the longest half-life and the highest thermal stability. Compared with the control group, low dose of four peptides had no significant effect on the survival rate and apoptosis of keloid fibroblasts tested by CCK-8 assay and flowcytometry. Transwell analysis showed that one peptides (PDHPS5) can significantly inhibit the cell migration ability (The optical density value in Control is 0.81±0.11, in PDHPS5 is 0.27±0.03, t=8.61, P=0.001). Western blot analysis showed that four peptides (PDHPS2, PDHPS3, PDHPS4, PDHPS5) can significantly inhibit the protein expressions of COL1A2 (The relative protein band intensity in Control is 1.02±0.02, in PDHPS2 is 0.21±0.04, in PDHPS3 is 0.26±0.03, in PDHPS4 is 0.53±0.04, in PDHPS5 is 0.73±0.04, t=31.38, 38.54, 18.88, 11.07 respectively, all P value are less than 0.01). Three peptides (PDHPS2, PDHPS3, PDHPS5) can significantly inhibit the protein expressions of ACTA2 (The relative protein band intensity in Control is 1.02±0.02, in PDHPS2 is 0.64±0.05, in PDHPS3 is 0.77±0.06, in PDHPS5 is 0.47±0.07, t=12.08, 6.38, 14.06 respectively, all P value are less than 0.01). In conclusion, the differentially expressed peptides in human hypertrophic scar tissue can affect the function of keloid fibroblasts and collagen expressions to varying degrees. Among them, two peptides (PDHPS2,PDHPS3) significantly inhibit the protein expressions of COL1A2 and ACTA2. The peptide PDHPS5 has high stability, significantly suppresses cell migration, and reduces the protein expressions of COL1A2 and ACTA2, which may provide a new strategy for scar prevention and treatment.

Objective　By exploring the function of sulfakinin (SK) and sulfakinin receptor (SKR) of Aedes aegypti, it laid a certain experimental basis and theoretical basis for the research and development of new insecticides targeting neuropeptides and their receptors. Methods　This study investigated the roles of SK and its receptor gene in Ae. aegypti using bioinformatics analysis and Clustered Regularly Interspaced Short Palindromic Repeats(CRISPR)/Cas9 knockout technology. Subsequently, RNA interference technology was employed to suppress the expression of SK or its receptor in adult mosquitoes. Lastly, transcriptome sequencing technology was utilized to identify and analyze differentially expressed genes between the interference group and the control group in order to gain insights into their functions. Results　It was found that there is only one SK receptor in Ae. aegypti. In addition, during the construction of mutant strains of Ae. aegypti SK and its receptor gene, it was found that only 2% of the G0 generation mutant strains mutated to form chimeras, with a large number of male chimeras dying, and only 14% of female chimeras being able to lay eggs, ultimately resulting in no effective G1 generation mutants. Transcriptome data showed, compared to the control group, 181 genes were significantly differentially expressed after interfering with the SK gene, with 62 genes significantly upregulated and 119 genes significantly downregulated. In addition, after interference with the sulfakinin receptor, 110 genes exhibited significant differential expression, including 20 upregulated and 90 downregulated genes. Cross-analysis of the two datasets identified 46 genes with significant expression changes after interference with sulfakinin or its receptor, with only 4 genes upregulated and the remaining 42 genes significantly downregulated, and the differentially expressed genes were mainly enriched in the metabolic pathway, endocrine system, and digestive system. Conclusions　The SK and its receptor gene are highly conserved and may primarily play roles in regulating the energy metabolism and digestion functions in Ae. aegypti, thus playing an important role in regulating insect growth and development.
