ObjectiveTo investigate the optimal termination time for acupuncture in treating patients with acute peripheral facial paralysis and its cost-effectiveness. MethodsA total of 120 eligible patients with acute-stage peri-pheral facial paralysis were randomly assigned to either the mild dysfunction termination group and the complete recovery termination group， with 60 patients in each group. Both groups received the standard acupuncture treatment protocol. Treatment in the mild dysfunction termination group was terminated when the Sunnybrook facial grade scale （SFGS） score first reached or exceeded 83 points， while that in the complete recovery termination group was terminated when the SFGS score first reached or exceeded 95 points. Assessments were conducted before treatment， 6 and 12 months after onset. SFGS， facial disability index （FDI） including physical function （FDIp） and social function （FDIs）， self-rating anxiety scale （SAS）， and self-rating depression scale （SDS） scores were assessed before treatment， and 6 and 12 months after onset. Any acupuncture-related adverse events during treatment were recorded for safety evaluation. Treatment sessions and medical costs including direct costs， indirect costs， insurance coverage， total societal costs， and patient out-of-pocket expenses were also recorded， and an economic evaluation was conducted including cost-effectiveness ratio （CER） and incremental cost-effectiveness ratio （ICER）. ResultsUltimately， 56 patients in the mild dysfunction termination group and 55 in the complete recovery termination group completed the follow-up. At 6 and 12 months after onset， SFGS and FDIp scores in both groups improved significantly while FDIs， SAS and SDS scores decreased （P＜0.05）. Comparison of scores between groups 6 months and 12 months after onset showed no statistically significant differences （P＞0.05）. During the trial， the incidence of adverse events was 13.3% （8/60） in the mild dysfunction termination group and 18.3% （11/60） in the complete recovery termination group， with no statistically significant difference （P＞0.05）. The number of treatment sessions， total social costs， and out-of-pocket expenses in the mild dysfunction termination group were significantly lower than those in the complete recovery termination group （P＜0.05）. The CER of the mild dysfunction termination group in SFGS， FDIp， FDIs， SAS， and SDS scores was lower than that of the complete recovery termination group. The ICER analysis showed that continuing treatment until full recovery incurred an additional cost of 573.30 CNY/point in SFGS improvement， whereas 1-point improvement in FDIp， FDIs， SAS， and SDS required 21,355.25 CNY， 1779.60 CNY， 3713.96 CNY， and 2755.52 CNY， respectively. ConclusionFor acupuncture in treating acute peripheral facial palsy， terminating treatment when mild dysfunction is achieved yields long-term efficacy comparable to that of continuing treatment until complete recovery， while significantly reducing medical costs and socioeconomic burden.

Objective:To evaluate the effect of terlipressin combined with dopamine on intraoperative renal perfusion and early postoperative renal function in patients undergoing living-donor kidney transplantation.Methods:In this prospective cohort study, 84 patients of either sex, aged 18-64 yr, with a body mass index of 18.5-28.0 kg/m 2, of American Society of Anesthesiologists Physical Status classification Ⅲ or Ⅳ, undergoing living-donor kidney transplantation at the First Affiliated Hospital of Zhengzhou University from September 2022 to July 2024, in whom dopamine was continuously infused during operation to maintain fluctuation in the mean arterial pressure within 10% of the baseline value, were selected and divided into dopamine group (group D, n=42) and dopamine+ terlipressin group (group DT, n=42) based on whether terlipressin was used during operation. Terlipressin was continuously infused at a constant rate even before induction in group DT. The renal artery resistance index, intraoperative urine output, urine output within 24 h after surgery, concentration of creatinine within 7 days after surgery, glomerular filtration rate and delayed postoperative transplanted renal function were recorded. Results:Compared with group D, the intraoperative renal vascular resistance index was significantly reduced, the intraoperative urine output was increased ( P<0.01), and no statistical change was found in the urine output within 24 h after surgery, concentration of creatinine within 7 days after surgery, glomerular filtration rate and incidence of delayed postoperative transplanted renal function in group DT ( P>0.05). Conclusions:Terlipressin combined with dopamine provides better efficacy than dopamine alone in improving intraoperative renal perfusion and exerts no effect on early postoperative renal function in patients undergoing living-donor kidney transplantation.

Objective:To analyze the pathogenicity and clinical phenotype associated with a newly identified heterozygous variant in the ZEB1 gene that causes posterior pleomorphic corneal dystrophy (PPCD). Methods:A pedigree study was conducted.Clinical data of four people in 2 generations from one family with PPCD who visited Henan Eye Hospital in October 2023 were collected, including 3 patients. Relevant ophthalmic examinations were performed.Best corrected visual acuity, slit lamp microscopy, intraocular pressure, Pentacam corneal topography, Corvis ST corneal biomechanics analyzer, corneal endothelial microscopy, swept-source anterior segment coherence optical tomography (CASIA), laser scanning confocal microscopy, and ultra-wide-field fundus photography were performed to examine clinical phenotypes.Peripheral venous blood samples were collected from family members to extract genomic DNA, and whole exome sequencing was performed.Sanger sequencing and pedigree co-segregation analysis were carried out.Conservation analysis was performed using GERP+ + and Clustal Omega software, and the pathogenicity of the variant was assessed according to American College of Medical Genetics and Genomics (ACMG) guidelines.This study protocol adhered to the Declaration of Helsinki and was approved by the Ethics Committee of Henan Eye Hospital (No.HNEECKY-2019[15]).All subjects or guardian signed informed consent.Results:This family conformed to autosomal dominant inheritance.Under a slit-lamp microscope, corneal endothelial vesicular lesions in both eyes could be seen in the proband, her father and her brother.Under a laser scanning confocal microscope, endothelial cells were missing at the lesions, and some were crater-like changes, and some lesions were circular or elliptical vesicular, and no other systemic abnormalities were observed.The ocular and physical examination of the proband's mother showed no abnormalities.Genetic testing results showed that the proband, her father and her brother all carried the ZEB1c.790G>A (p.Gly264Arg) heterozygous variant, but her mother did not carry the variantion.Sanger sequencing verified that this variantion was co-segregated within the family.The variantion is a newly discovered missense mutation that had not been reported in the Thousand Genomes Project, Genome Aggregation Database, and ExAC database.The prediction results of the variant by MutationTaster, SIFT, PROVEAN, VESST3, DANN, FATHMM-MKL, CADD, fitCons and other software were harmful, and GERP+ +, Weblogo, Clustal Omega analysis showed that the amino acids affected by the variant were highly conservative.According to the ACMG Guidelines, this variation was possible pathogenic.Conclusions:The identification of the missense mutation c. 790G>A (p.Gly264Arg) in the ZEB1 gene within this PPCD family provides new insights into the genetic basis of PPCD and the variant may be the pathogenic variant of in this family.

Objective To explore the changes in neural activity in patients with type 2 diabetes mellitus(T2DM)and their corre-lation with executive function,and to analyze the neural mechanisms underlying the decline in executive function in T2DM patients.Methods Thirty-one T2DM patients(T2DM group)and thirty-two healthy controls(HC)(HC group)matched for body mass index(BMI)underwent resting-state functional magnetic resonance imaging(rs-fMRI)scans and N-back task tests were included.Differ-ences in the amplitude of low-frequency fluctuation(ALFF),regional homogeneity(ReHo),and seed-based functional connectivity(FC)between the two groups were compared,and partial correlation analyses were performed between the difference results and N-back task performance.Results The T2DM group showed prolonged reaction time(RT)in the 1-back and 2-back tasks.T2DM patients exhibited increased ALFF in the bilateral caudate nucleus,left medial superior frontal gyrus,and right postcentral gyrus,as well as elevated ReHo in the right putamen.FC analysis revealed significant alterations in FC between the caudate nucleus,putamen,and multiple brain regions in T2DM patients,with some of these FC changes significantly correlated with RT and accuracy(ACC)in the N-back task.Conclusion The decline in executive function in T2DM patients may be associated with abnormal neural activity in brain regions such as the striatum,salience network,and frontoparietal control network.FC further decreases under increased cognitive load.These findings provide evidence for the study of the neural mechanisms of executive function impairment in T2DM patients.

BACKGROUND:The extracellular matrix is a complex network structure,which not only builds physical support for tissue cells,but also plays an important regulatory role in cell survival,proliferation,and death.Abnormal changes in the biochemical and biomechanical properties of the extracellular matrix can significantly affect the proliferation,migration,immune evasion,and treatment resistance of tumor cells.Stiffness is an important mechanical property of the extracellular matrix,and abnormalities in matrix stiffness are closely related to tumor progression.OBJECTIVE:By reviewing the mechanism of extracellular matrix sclerosis,the impact of high stiffness matrix on tumor progression,and the latest research progress in the treatment of cancer based on reducing matrix stiffness,to deeply understand the mechanical properties of the extracellular matrix,improve the understanding of the complex mechanism of tumor progression,and provide new ideas and directions for tumor treatment.METHODS:"Extracellular matrix function,extracellular matrix stiffness,collagen deposition cross-linking,extracellular matrix stiffness therapy,immunotherapy"were used as the search terms in Chinese and English.Relevant literature published from January 2016 to June 2024 was searched in CNKI,PubMed,and WanFang databases,and 80 articles were finally included for review.RESULTS AND CONCLUSION:(1)Deposition and excessive cross-linking of collagen and elastin in the extracellular matrix leads to matrix remodeling,which in turn increases matrix stiffness.This sclerosis activates pro-cancer signaling pathways such as cyclin-D1,Rho/ROCK,p-PXN-Rac1-YAP,and STAT3/p-STAT3,promotes malignant behaviors such as cancer cell proliferation,metastasis,tumor microangiogenesis and immune escape,and accelerates tumor progression.(2)Reducing the deposition and cross-linking of matrix proteins can reduce matrix stiffness,which cannot only inhibit the activation of multiple cancer-promoting signaling pathways,but also enhance the penetration and delivery of drugs at tumor sites,which is a new strategy for cancer treatment.(3)At present,drugs based on matrix degradation to reduce tumor stiffness are under development,and a few drugs have entered the clinical trial stage,which are expected to provide a new powerful weapon for tumor treatment.
