ObjectiveTo observe the effects of Dihuang Yinzi （DY） on motor dysfunction in rats with advanced Parkinson's disease （PD） and to investigate the mechanisms by which DY improves advanced PD symptoms through the "gut microbiota-short-chain fatty acids （SCFAs）-inflammation-neuroprotection pathway". MethodsAn advanced PD rat model was induced by rotenone. Rats were divided into a normal group， model group， positive drug group （levodopa， 50 mg·kg^-1）， and DY low-， medium-， and high-dose groups （5.2， 10.4， 20.8 g·kg^-1）. After 7 days of administration， motor function was evaluated using the open-field， pole-climbing， and inclined plate tests. Hematoxylin-eosin （HE） staining was used to observe pathological changes in the substantia nigra and colon， and immunohistochemistry was performed to detect α-Synuclein （α-Syn） and tyrosine hydroxylase （TH） expression in the substantia nigra. Enzyme-linked immunosorbent assay （ELISA） was used to measure levels of dopamine （DA）， 5-hydroxytryptamine （5-HT）， 3，4-dihydroxyphenylacetic acid （DOPAC）， Levodopa， homovanillic acid （HVA）， tumor necrosis factor-α （TNF-α）， interleukin-6 （IL-6）， and interleukin-1β （IL-1β）. Western blot analysis was used to detect the expression of zonula occludens-1 （ZO-1） and occludin. Gut microbiota diversity was analyzed by 16S rRNA sequencing， and gas chromatography （GC） was used to determine the content of SCFAs in colonic contents. ResultsCompared with the normal group， the model group showed significantly decreased movement speed and distance in the open-field test， prolonged pole-climbing time， and reduced retention angle on the inclined plate （P<0.01）， accompanied by increased α-Syn expression （P<0.01） and decreased TH expression （P<0.01） in the brain. Compared with the model group， all DY dose groups improved motor dysfunction in advanced PD rats to varying degrees （P<0.05， P<0.01） and alleviated pathological damage in the brain and colon. High-dose DY significantly reduced α-Syn aggregation in the substantia nigra （P<0.01） and increased TH expression （P<0.01）. ELISA and Western blot results showed that， compared with the normal group， the model group exhibited decreased levels of DA， 5-HT， DOPAC， Levodopa， and HVA in the striatum （P<0.01）， increased levels of TNF-α， IL-6， and IL-1β in the colon and striatum （P<0.01）， and significantly reduced expression of ZO-1 （P<0.05） and occludin in the colon （P<0.01）. Compared with the model group， all DY dose groups increased the levels of DA， 5-HT， DOPAC， Levodopa， and HVA in the striatum to varying degrees （P<0.05， P<0.01）. In the high-dose DY group， the levels of TNF-α， IL-6， and IL-1β in the colon and striatum were reduced （P<0.01）， while the expression of ZO-1 （P<0.05） and occludin in the intestine was increased. The 16S rRNA sequencing results indicated that the relative abundances of Actinobacteriota， Enterobacteriaceae， and Erysipelotrichaceae were increased in the model group， whereas the relative abundances of Bacteroidota， class Clostridia， Lachnospiraceae， and Akkermansia muciniphila were decreased. These changes were effectively reversed after high-dose DY intervention. GC analysis showed that the content of SCFAs in the colonic contents of rats in the model group was decreased （P<0.05， P<0.01）， while after high-dose DY intervention， the levels of acetate， propionate， isobutyrate， and butyrate were significantly increased （P<0.05， P<0.01）. ConclusionDY may exert therapeutic effects in advanced PD by regulating the gut microbiota-SCFAs-inflammation pathway.

Diabetic kidney disease（DKD） is a chronic kidney structural and functional disorder caused by diabetes. With the global prevalence of diabetes continuing to rise， DKD has gradually become a major cause of chronic kidney disease and end-stage renal disease（ESRD）， posing a serious threat to patients' quality of life and long-term health outcomes. Studies have shown that apoptosis plays a pivotal role in the development and progression of DKD， with its mechanisms involving abnormal activation of multiple signaling pathways such as Toll-like receptor 4（TLR4）/nuclear transcription factor-κB（NF-κB）/B-cell lymphoma-2（Bcl-2）/cysteinyl aspartate-specific proteinase（Caspase）-3， protein kinase R-like endoplasmic reticulum kinase（PERK）/eukaryotic initiation factor 2α（eIF2α）/activating transcript factor 4（ATF4）/CCAAT enhancer-binding protein homologous protein（CHOP）， phosphatidylinositol 3-kinase（PI3K）/protein kinase B（Akt）/glycogen synthase kinase-3β（GSK-3β）， Janus kinase 2（JAK2）/signal transducer and activator of transcription 3（STAT3）， adenosine monophosphate-activated protein kinase（AMPK）/mammalian target of rapamycin（mTOR） and silent information regulator 1（SIRT1）/tumor suppressor protein 53（p53）， thereby accelerating renal pathological damage in DKD. Extensive evidence-based medical studies have confirmed that traditional Chinese medicine（TCM）， leveraging its unique therapeutic advantages of multi-target， multi-component and multi-pathway approaches， has demonstrated remarkable efficacy and favorable safety profiles in treating DKD. Recent studies have demonstrated that active components of TCM can specifically target and modulate key effectors in apoptotic signaling pathways. Meanwhile， traditional compound formulations exert synergistic effects through multiple approaches such as replenishing deficiency and activating blood circulation， detoxifying and dredging collaterals， tonifying kidney essence， and removing stasis and purging turbidity， thereby comprehensively regulating critical pathological processes including endoplasmic reticulum stress and mitochondrial apoptosis pathways. This combined therapeutic approach of molecular targeting and holistic regulation provides novel strategies for delaying the progression of DKD. Based on this， this paper provides an in-depth analysis of key apoptotic signaling pathways and their regulatory mechanisms， while systematically summarizing recent research advances regarding the therapeutic effects of TCM active components， compound formulations， and proprietary Chinese medicines on DKD through modulation of these pathways， with particular emphasis on their underlying molecular mechanisms. These findings not only elucidate the modern scientific connotation and theoretical basis of TCM in treating DKD but also establish a solid theoretical and practical foundation for promoting the wider clinical application and further research of TCM in the field of DKD treatment.

Objective:To explore the role of process management for continuous periheral insulin infusion (CPII) for controlling hyperglycemia during enteral nutrition (EN) for critically ill patients.Methods:A total of 75 patients who received continuous EN treatment in the emergency intensive care unit (EICU) of Qinghai Red Cross Hospital from January 2023 to January 2024 were selected in this historical controlled trial study. Patients who were admitted before the implementation of process management for CPII were included in the historical control group ( n=35), and those who were admitted after the implementation were included in the observation group ( n=40). Both groups were treated with continuous EN infusion combined with micropump-based insulin therapy, with the target blood glucose being<10 mmol/L. The blood glucose values at 4 hours and 8 hours after treatment, the time to reach the target blood glucose and the dosage of insulin, the total amount of insulin at 24 hours, the amount of calories administered when reaching the target blood glucose, the frequency of blood glucose measurement, the incidence of hypoglycemia and hypokalemia, the amount of potassium supplemented for hypokalemia, the length of EICU stay, and the incidence of nosocomial infection were compared between these two groups. Results:The blood glucose levels of the observation group at 4 hours and 8 hours after CPII were significantly lower than those of the control group (both P<0.001), and the time for the observation group to reach the target blood glucose level was significantly shorter than that for the control group ( P<0.001). The total amount of insulin in the observation group when reaching the target blood glucose and the total amount of insulin used within 24 hours were significantly smaller than those in the control group (both P<0.05). The amount of calories administered to the observation group when reaching the target blood glucose level was significantly higher than that of the control group ( P=0.002). The number of blood glucose measurements within 24 hours after insulin initiation in the observation group was significantly larger than that in the control group ( P=0.042), but there was no statistically significant difference in the total number of monitoring during EICU stay ( P=0.561). The incidence rates of hypoglycemia and hypokalemia and the amount of potassium supplemented for hypokalemia in the observation group were significantly lower than those in the control group (all P<0.05). There was no statistically significant difference in the length of EICU stay and the incidence of nosocomial infection between the two groups (both P>0.05). Conclusions:Process management for CPII in critically ill patients promotes rapid glycemic control during enteral nutrition (EN), reduces hypoglycemia, hypokalemia, and nosocomial infections, and improves overall blood glucose stability. It is vital for controlling stress hyperglycemia during EN in critical illness, with excellent safety.

Objective:To survey the relationship among parents'rearing style,family conformity and obsess-ive-compulsive symptoms in patients with obsessive-compulsive disorder(OCD).Methods:Totally 216 patients di-agnosed with OCD were recruited(59 cases of mild obsessive-compulsive symptoms,121 cases of moderate obsess-ive-compulsive symptoms,36 cases of severe obsessive-compulsive symptoms).They were assessed with the Yale-Brown Obsessive-Compulsive Disorder Scale(Y-BOCS),Egma Minnen av Bardndosna Uppforstran(EMBU),and Family Accommodation Scale for Obsessive-Compulsive Disorder-Patient Version(FAS-PV).Results:The severe obsessive-compulsive symptom group had the lowest positive parenting style scores.Conversely,they had the high-est negative parental rearing scores and total FAS-PV scores(Ps＜0.01).The ordered logistic regression results showed that male patients had less severe obsessive-compulsive symptoms(OR=0.22).Patients with lower years of education(OR=0.87)and positive parental rearing scores(OR=0.98,0.97)had more severe obsessive-com-pulsive symptoms.Conversely,higher negative paternal rearing scores(OR=1.02)and total FAS-PV scores(OR=1.04)were associated with more severe obsessive-compulsive symptoms.Conclusion:This study suggests that the severity of obsessive-compulsive symptoms is related to parental rearing style and family accommodation.Patients with severe obsessive-compulsive symptoms are more likely to feel negative paternal rearing style and higher level of family compliance,and less likely to feel positive parental rearing style.

Objective To address the personalized differences in motion gait between stroke patients and healthy older adults,as well as the issue of abnormal gait recognition,a deep learning fusion-based approach is proposed to effectively improve the accuracy of abnormal gait recognition.Methods A model fusing convolutional neural networks(CNN)and bidirectional long short-term memory networks(BiLSTM)was adopted,with the introduction of a residual network(ResNet).Unilateral ankle joint movement data at different walking speeds within a comfortable range were collected from healthy older adults and stroke patients.Signals from inertial sensors and electromyography sensors were used as inputs,while gait features were analyzed and gait differences between the two groups were compared.The effectiveness of the model was validated by comparing the classification performance of traditional deep learning models and CNN-ResNet-BiLSTM models with different layer combinations in terms of abnormal gait recognition accuracy.Results The CNN-ResNet-BiLSTM model,which introduced residual connectivity,performed excellently in abnormal gait recognition.Compared with traditional deep learning models such as the gated recurrent unit(GRU)and long short-term memory network(LSTM),its prediction accuracy was improved by 13.6％and 8.36％,respectively.Additionally,compared with other model combinations,this model achieved an overall accuracy of 97.78％.Conclusions The algorithm proposed in this study can be applied to stroke-related abnormal gait detection,providing technique support for the early diagnosis and precise monitoring of such diseases.

Objective:To investigate the influencing factors of green procurement for medical equipment,so as to provide theoretical basis and policy insights for promoting practices of green procurement for medical institutions.Methods:Based on literature review and expert interviews,a questionnaire about influencing factors of green procurement for medical equipment was formulated,which was used to conduct questionnaire survey for medical institutions of secondary and tertiary grades in Shandong province.The questionnaire included the measured indicators and basic information of medical institutions from four dimensions:pressure of external system(7 items),leadership support(4 items),organizational inertia(5 items),and collaboration degree of stakeholder(5 items).The Likert 5-level scale was adopted to conduct scoring of questionnaire,and the differences in various influencing factors between secondary grade hospital and tertiary grade hospital were compared and analyzed.Results:The scores of tertiary grade hospital were respectively 4.00(3.14,4.82),4.25(4.00,5.00),and 3.60(3.00,4.00)at pressure of external system,leadership support(4 items),organizational inertia(5 items)of three dimensions,and they were 3.86(3.11,4.14),4.00(3.75,5.00),and 3.20(2.80,3.80)at secondary grade hospital,and the differences of them between secondary grade hospital and tertiary grade hospital were significant(Z=-2.243,-2.654,-2.538,P<0.05).There was not significant difference at the dimension of collaboration degree of stakeholder between secondary and tertiary hospitals(P>0.05).Conclusion:A series of measures,such as adopting policy support with differentiation,establishing multi-level incentive mechanisms,reducing organizational change resistance,and improving multi-party coordination mechanisms,can further promote green procurement of medical institutions.

Objective:To quantitatively summarize the catechol-O-methyltransferase ( COMT) gene Val158Met polymorphism and the risk of obsessive-compulsive disorder (OCD). Methods:We searched databases including PubMed, Embase, Weipu and Wanfang for randomized controlled trials (RCTs) investigating the association between COMT gene polymorphisms and OCD up to November 1, 2023. Studies that reported genotype frequencies for both OCD patients and general healthy controls were included. Stata11 software was used to calculate pooled odds ratios ( OR) with 95% CI, perform heterogeneity test, and assess publication bias. Results:19 studies with 2, 393 OCD patients and 4, 134 healthy controls were included. The overall results showed that the Val158Met polymorphism was associated with OCD patients (allele model: OR=1.10, 95% CI: 1.02-1.20, P=0.016; homozygote model: OR=1.25, 95% CI:1.05-1.49, P=0.014; recessive model: OR=1.18, 95% CI:1.01-1.37, P=0.040). In the ethnic-stratified analysis, this significant association was mainly observed in Caucasians (allele model: OR=1.17, 95% CI:1.06-1.30, P=0.003; homozygote model: OR=1.35, 95% CI: 1.08-1.67, P=0.008; recessive model: OR=1.21, 95% CI: 1.01-1.44, P=0.041; dominant: OR=1.20, 95% CI: 1.01-1.43 P=0.040), but not in Asians. In gender-stratified analysis, Met-homozygote was associated with male OCD ( OR=1.75, 95% CI: 1.00-3.04, P=0.049). Moreover, the additional analysis found that the risk of OCD was significantly increased in Caucasian males (allele model: OR=1.48, 95% CI: 1.08-2.03, P=0.014; heterozygote model: OR=1.41, 95% CI: 1.03-1.93, P=0.030; dominant model: OR=1.60, 95% CI:1.08-2.38, P=0.020). Conclusion:This meta-analysis suggests that the COMT gene Val158Met polymorphism is associated with an increased risk of OCD in males, particularly in Caucasian males.

Objective:To summarize the best evidence for oral nutrition management of patients with inflammatory bowel disease (IBD) and to evaluate its effectiveness.Methods:From May 2023 to March 2024, IBD patients, the medical and nursing staff in the Department of Proctology, Zhongshan Hospital of Traditional Chinese Medicine Affiliated to Guangzhou University of Traditional Chinese Medicine, were selected as study subjects using convenience sampling method. Evidence-based nursing was used to summarize the best evidence for oral nutrition management of IBD patients, formulate review indicators, develop best evidence-based practice programs for clinical application through status review and barrier factor analysis. Effectiveness was evaluated at the system level, medical and nursing staff level, and patient level.Results:After evidence-based practice, a multidisciplinary management team and management system for oral nutrition was established at the system level. At the medical and nursing staff level, the oral nutrition knowledge score increased from [50.00 (40.00, 60.00) ] to [100.00 (85.00, 100.00) ], with a statistically significant difference ( P<0.01), and the implementation rate of the three review indicators improved from 0 to 100.00%. At the patient level, oral nutrition knowledge and attitude scores improved from [10.00 (8.00, 12.00) ] and [35.00 (31.00, 40.00) ] to [16.00 (16.00, 16.00) ] and [48.00 (45.00, 48.00) ], respectively, with statistically significant differences ( P<0.01), and the implementation rate of each of the review indicators rose above 80.00% except for indicator 6. The patients' nutrition indicators, including body mass index, waist circumference, left upper arm midpoint circumference and left hand grip strength were improved, and the difference was statistically significant ( P<0.05) . Conclusions:The implementation of evidence-based practice programs can improve the standardization of clinical work of healthcare professionals, enhance patients' nutrition knowledge and attitude, and promote their rational dietary behaviors, thus improving their nutrition status and quality of life.
