ObjectiveTo observe the prevention and control effect of processed Polygonatum cyrtonema on depression induced by chronic unpredictable mild stress （CUMS） in female rats. MethodsForty rats were assigned into control， model， and low-， medium-， and high-dose processed P. cyrtonema groups according to the random number table method， with 8 rats in each group. The rat model of depression was established with the CUMS method. The body mass， open field test， forced swimming test， Morris water maze test， levels of neurotransmitters ［dopamine （DA）， 5-hydroxytryptamine （5-TH）， and acetylcholine （ACh）］， serum levels of sex hormones ［gonadotropin-releasing hormone（GnRH）， testosterone （T）， and estradiol （E₂）］ and inflammatory factors ［tumor necrosis factor-α （TNF-α）， interleukin （IL）-6， and IL-10］， and mRNA and protein levels of factors in the brain-derived neurotrophic factor （BDNF）/tyrosine kinase receptor B （TRKB）/cAMP-response element binding protein （CREB） pathway were employed to evaluate the effect of processed P. cyrtonema on the CUMS-induced depression in female rats. ResultsThe body mass， open field test results， and forced swimming test results showed that the rat model of depression was successfully established. The comparison of behaviors， neurotransmitters， sex hormones， inflammatory factors， and neural pathways among groups showed that processed P. cyrtonema had different effects of preventing the development of depression in female rats. SPSS 25 was used for statistical analysis of error and significance. T test was conducted between groups. Each treatment group showed significant therapeutic effect compared with the model group （P<0.05）. Processed P. cyrtonema elevated the level of 5-TH （P<0.01） and lowered the levels of DA and ACh （P<0.01） in the brain tissue of female rats. In addition， it reduced the serum levels of GnRH， T， E₂， TNF-α， and IL-6 （P<0.05） and up-regulated the mRNA levels of BDNF and TRKB in the rat brain. ConclusionProcessed P. cyrtonema has a non-hyperactive preventive effect on CUMS-induced depression in rats， which provides a theoretical basis for the development of processed P. cyrtonema as a functional food product.

Congenital myasthenic syndrome（CMS）is a group of neuromuscular transmission disorders caused by genetic defects，and it is characterized by an early age of onset，fatigable weakness of skeletal muscle，and a high disability rate，with respiratory failure as a common cause of death. Endplate acetylcholinesterase deficiency（EAD）caused by COLQ gene mutations is a subtype of CMS，and repetitive compound muscle action potential（R-CMAP）in nerve conduction examination is the key evidence for diagnosis. The heterogeneity of clinical phenotypes of CMS often leads to misdiagnosis or missed diagnosis，resulting in delayed treatment. This article reports a case of CMS caused by COLQ mutation and summarizes the pathogenesis，mechanisms，clinical manifestations，electrophysiological characteristics，differential diagnosis，treatment，and prognosis of the disease with reference to relevant literature，in order to improve the understanding of this subtype of CMS among clinicians.

BACKGROUND: The available evidence regarding the benefits of percutaneous coronary intervention (PCI) on patients receiving dialysis with coronary artery disease (CAD) is limited and inconsistent. This study aimed to evaluate the association between PCI and clinical outcomes as compared with medical therapy alone in patients undergoing dialysis with CAD in China. METHODS: This multicenter, retrospective study was conducted in 30 tertiary medical centers across 12 provinces in China from January 2015 to June 2021 to include patients on dialysis with CAD. The primary outcome was major adverse cardiovascular events (MACE), defined as a composite of cardiovascular death, non-fatal myocardial infarction, and non-fatal stroke. Secondary outcomes included all-cause death, the individual components of MACE, and Bleeding Academic Research Consortium criteria types 2, 3, or 5 bleeding. Multivariable Cox proportional hazard models were used to assess the association between PCI and outcomes. Inverse probability of treatment weighting (IPTW) and propensity score matching (PSM) were performed to account for potential between-group differences. RESULTS: Of the 1146 patients on dialysis with significant CAD, 821 (71.6%) underwent PCI. After a median follow-up of 23.0 months, PCI was associated with a 43.0% significantly lower risk for MACE (33.9% [ n  = 278] vs . 43.7% [ n  = 142]; adjusted hazards ratio 0.57, 95% confidence interval 0.45-0.71), along with a slightly increased risk for bleeding outcomes that did not reach statistical significance (11.1% vs . 8.3%; adjusted hazards ratio 1.31, 95% confidence interval, 0.82-2.11). Furthermore, PCI was associated with a significant reduction in all-cause and cardiovascular mortalities. Subgroup analysis did not modify the association of PCI with patient outcomes. These primary findings were consistent across IPTW, PSM, and competing risk analyses. CONCLUSION This study indicated that PCI in patients on dialysis with CAD was significantly associated with lower MACE and mortality when comparing with those with medical therapy alone, albeit with a slightly increased risk for bleeding events that did not reach statistical significance.

Objective To investigate the impact of catheter-associated urinary tract infection(CAUTI)on the prognosis of neurosurgical inpatients with indwelling catheters.Methods Neurosurgical inpatients with indwelling catheters and hospital stays＞2 days from January 2018 to December 2023 were selected as the study subjects.CAUTI during hospitalization was used as the exposure factor.A 1∶2 propensity score matc-hing method was applied to control for confounding factors,subsequently,63 patients were included in the CAUTI group and 121 in the non-CAUTI group.The impact of CAUTI on prognostic indicators in these pa-tients was analyzed.Results A total of 554 neurosurgical inpatients with indwelling catheters were included,among whom 70 developed CAUTI,yielding an infection rate of 12.64％.After propensity score matching,compared with the non-CAUTI group,the CAUTI group showed significantly longer hospital stays and in-dwelling catheter durations,higher total hospitalization costs,and higher out-of-pocket expenses,the differ-ences were statistically significant(P＜0.05).However,there was no significant difference in mortality be-tween the two groups(P＞0.05).Among the various medical cost items,significant differences were observed in medical service fees,diagnostic fees,other treatment fees,Western medicine fees,antibacterial drug fees,traditional Chinese medicine fees,consumable costs,and other expenses(P＜0.05),while no significant differ-ence was found in surgical treatment fees(P＞0.05).Conclusion CAUTI prolongs hospital stays and in-dwelling catheter durations,and increases medical costs.Effective measures should be taken to prevent and control CAUTI,thereby improving patient prognosis,reducing patients' direct financial burden,and enhancing the utilization of medical resources.

IgA nephropathy（IgAN）is a common primary glomerular disease in children，characterized by the deposition of IgA or IgA-dominant immune complexes in the glomeruli.The clinical manifestations are highly heterogeneous，with some children progressing to end-stage renal disease.The prognosis of IgAN is influenced by multiple factors，involving clinical，pathological，and laboratory examinations.Among the clinical factors，persistent proteinuria，reduced baseline estimated glomerular filtration rate（eGFR），hypertension during follow-up，and hyperuricemia are risk factors for poor prognosis.The predictive value of hematuria remains controversial.Pathologically，the Oxford classification highlights that segmental sclerosis，tubular atrophy/interstitial fibrosis，and crescents are significantly associated with disease progression，with tubular atrophy/interstitial fibrosis serving as an independent risk factor for poor outcomes.The prognostic significance of mesangial hypercellularity and endocapillary hypercellularity requires further validation.Among the biomarkers，serum galactose-deficient IgA 1 and complement-related markers（such as IgA/C3 ratio）show potential predictive value，but need to be supported by large samples studies.This article reviews the clinical，pathological，and biomarker-related risk factors influencing the prognosis of pediatric IgAN，aiming to provide basis for developing risk prediction models and guiding individualized treatment strategies.

Objective To investigate the sleep disorders and its effects on the changes in quality of life in patients with liver cancer from the hospital admission to 6 months after surgery and to analyse the correlation between the sleep disorder and quality of life.Methods A total of 214 patients who underwent surgery for liver cancer for the first time were included in the study.Demographic questionnaire,Pittsburgh sleep quality index(PSQI),and functional assessment of cancer therapy-hepatobiliary(FACT-Hep)were used for the investigation at admission and at 1,3 and 6 months after surgery.Multiple linear regression was employed to analyse the correlation between the sleep disorders at the admission and its effect on quality of life up to 6 months after surgery.Results Toally 214 patients finished the study at admission and 209 finished the study 1 month after surgery,and 208 finished the stuoly 3 months after surgery,and 205 patients finished the study 6 months after surgery.The scores of both of PSQI at admission and the quality of life at 6 months after surgery varied across the tested time points with a statistically significant difference(both P<0.001).The overall level of sleep disorder in the patients showed a characteristic pattern with initially increasing and then decreasing,and the quality of life presented a characteristic tendency of starting from high to low and then gradually increasing.It showed that the sleep disorder at admission was attributive to the poorer quality of life at 6 months after surgery.The hierarchical regression analysis showed that among the patients at BCLC Stage A,sleep disorder at admission was the influencing factor of the quality of life at 6 months after surgery.Conclusions The sleep disorder and quality of life in the patients who had surgical operations for hepatocellular carcinoma both changed dynamically from admission to the 6 months after surgery.The quality of life was poor in the patients with sleep disorder at admission.Therefore,medical staff should enhance the sleep management at admission,conduct dynamic assessment of the sleep disorder and quality of life of the patients,and then develop continuity nursing measures to improve the quality of life after surgery.

Objective To establish a noninvasive diagnostic model for liver fibrosis in chronic hepatitis B(CHB)patients with normal alanine aminotransferase(ALT)and an age of≤30 years by selecting specific indicators from the commonly used noninvasive indicators such as clinical,biochemical,and imaging indicators,to avoid invasive liver biopsy in such patients to some extent,and to guide the timing of antiviral therapy.Methods A total of 251 CHB patients with normal ALT and an age of≤30 years who underwent liver biopsy in Shenzhen Third People's Hospital and The First Hospital of Changsha from January 2019 to January 2022 were enrolled,with 175 patients in the model group and 76 patients in the validation group,and commonly used clinical indicators were obtained based on clinical experience and related articles.The two-independent-samples t test or the two-independent-samples Mann-Whitney U rank sum test was used for comparison of continuous data between groups,and the chi-square test was used for comparison of categorical data between groups.A Spearman rank correlation analysis was used to investigate the correlation between each indicator and liver fibrosis and identify the indicators with correlation(P<0.01,r>0.200);a Logistic regression analysis was used to establish a noninvasive diagnostic model,and the receiver operating characteristic(ROC)curve was used to evaluate its performance and perform validation of the model;this model was then compared with the widely used models of aspartate aminotransferase-to-platelet ratio index(APRI)and fibrosis-4(FIB-4).The Kappa consistency test was used to investigate the consistency of pathological results.Results A total of 17 commonly used clinical indicators were obtained,among which 9 indicators(ALT,aspartate aminotransferase[AST],gamma-glutamyl transpeptidase[GGT],ferritin[FERR],platelet count[PLT],procollagen type Ⅲ amino-terminal peptide[PⅢP],collagen Ⅳ[CⅣ],HBV DNA,and spleen thickness)were correlated with liver fibrosis(P<0.01,r>0.232).Based on the above indicators,the predictive model was established as P=1/(1+e-γ),γ=-1.902+0.106×AST-0.011×PLT-0.265×HBV DNA+0.059×PⅢP,in which P was the probability for predicting≥S2 liver fibrosis and γ was the predictive index.The comparison between each indicator and the model showed that the model had the largest area under the ROC curve of 0.852,with a sensitivity of 92.7%and a specificity of 76.9%.The model was validated in 76 patients and showed an accuracy of 77.600%.The model was compared with APRI and FIB-4,and the results showed that the model has good accuracy.Conclusion Compared with the models of APRI and FIB-4 commonly used in the world,this model can more accurately judge the degree of liver fibrosis in such patients,thereby replacing liver biopsy to some extent and guiding the timing of antiviral therapy.

Objective Exploring the relationship between changes in serum Golgi apparatus transmem-brane glycoprotein 73(GP73)and chitosanase 3-like protein 1(CHI3L1)levels and liver fibrosis and lesion sever-ity in patients with hepatitis B(CHB).Methods Using a case-control study,80 patients diagnosed with CHB infection and developing liver fibrosis in the Infectious Disease Department of Changsha First Hospital from June 2020 to June 2023 were selected as the liver fibrosis group,while 120 patients diagnosed with CHB infection but not developing liver fibrosis in the Infectious Disease Department of our hospital were selected as the control group.The serum GP3,CHI3L1,liver function,and fibrosis indicators of the two groups of patients were compared,and the liver fibrosis group was divided into mild according to Scheuer system standards Perform stratified analysis on patients with significant liver fibrosis.Results The serum GP3 and CHI3L1 levels in the liver fibrosis group were significantly higher than those in the control group,with statistical significance(P＜0.05);The ROC curves were plotted using serum GP3,CHI3L1,and GP3+CHI3L1,respectively.The sensitivity for diagnosing liver fibrosis in CHB patients was 62.81%,60.94%,and 96.33%,with specificity of 80.66%,80.05%,and 75.30%.The AUC values under the curves were 0.792,0.756,and 0.908,respectively;The levels of ALT,AST,HA,LN,PC III NP,C IV,and CG in the liver fibrosis group were higher than those in the control group,and the PLT measurement values were lower than those in the control group,with statistical significance(P＜0.05);49 patients with moderate to severe liver fibrosis(33 in S2 phase and 16 in S3 phase)and 31 patients with mild liver fibrosis(all in S1 phase)had significantly higher serum GP3 and CHI3L1 levels than mild patients,with statistical significance(P＜0.05);The levels of DBIL,ALT,AST,HA,LN,PC III NP,C IV,and CG in patients with moderate to severe liver fibrosis were higher than those in the mild group,and the PLT measurement values were lower than those in the mild group,with statistical significance(P＜0.05).Conclusion The serum GP3 and CHI3L1 levels in CHB patients with liver fibrosis are significantly elevated,and there is a certain correlation with the degree of liver fibro-sis.The combination of these two indicators is beneficial for diagnosing liver fibrosis in CHB patients.

Objective:To explore the utility of combining repeated transcranial magnetic stimulation (rTMS) with action observation therapy (AOT) in improving the upper limb motor functioning of children with hemiplegic spastic cerebral palsy (HSCP).Methods:A total of 66 children with HSCP were randomly divided into a sham stimulation group, an rTMS group and a combination group, each of 22. In addition to routine rehabilitation, the sham stimulation and rTMS groups received the relevant treatment or sham treatment, while the combination group also received action observation therapy (AOT). The treatment was administered daily, five times a week for 12 weeks. Before and after the treatment, everyone′s upper limb muscle tone was evaluated using the modified Ashworth Scale (MAS), and fine motor function, grasping and hand coordination were quantified using the fine component of the Peabody Motor Development Scale (PDMS-FM) and the Carroll upper limb function test (UEFT).Results:After the treatment, significant improvement was documented in the average MAS scores of the bicipital arm and wrist flexors of all three groups, and also in their average PDMS-FM scores, fine motor quotient (FMQ) scores and UEFT scores. After 12 weeks the combination group significantly out-scored the other two groups in terms of their average biceps and wrist flexor MAS scores, PDMS-FM grasping area and visual-motor integration area scores, FMQ score and UEFT score. There was no significant difference between the other two groups in any of the outcome measurements, on average.Conclusions:Supplementing rTMS and routine rehabilitation with AOT more effectively improves the upper limb muscle tension, upper limb functioning and fine finger manipulation of children with hemiplegic spastic cerebral palsy.
