Objective To observe the clinical efficacy of acupuncture combined with western medicine in the treatment of lumbar disc herniation(LDH)of qistagnation and blood stasis type.Methods A total of 62 cases of patients with LDH of qistagnation and blood stasis type were randomly divided into observation group and control group,with 31 cases in each group.The control group was given conventional western medicine for treatment,and the observation group was treated by acupuncture on the basis of the control group,the course of treatment covered three consecutive weeks.After three weeks of treatment,the clinical efficacy of the two groups was evaluated,and the changes in the Japanese Orthopedic Association(JOA)scores and Oswestry Disability Index(ODI)scores,as well as the Visual Analogue Scale(VAS)scores of pain,were observed before and after the treatment of the patients in the two groups.The changes in muscle tension,muscle hardness,and muscle elasticity of the multifidus muscle(MM)and lumbar multifidus muscle(LMM)before and after treatment were compared between the two groups.And the safety and the occurrence of adverse reactions in the two groups were evaluated.Results(1)The total effective rate was 96.77%(30/31)in the observation group and 74.19%(23/31)in the control group.The efficacy of the observation group was superior to that of the control group,the difference being statistically significant(P<0.05).(2)After treatment,the VAS,JOA,and ODI scores of the patients in the two groups improved significantly(P<0.05),and the improvement in the observation group was significantly superior to that in the control group,with a statistically significant difference(P<0.01).(3)After treatment,the muscle tension,muscle hardness,and muscle elasticity of LMM and MM of patients in the two groups were significantly improved(P<0.05),and the improvement in the observation group was significantly superior to that in the control group,the difference being statistically significant(P<0.05).(4)The incidence rate of adverse reactions was 9.68%(3/31)in the observation group and 9.68%(3/31)in the control group;the intergroup comparison showed that there being no statistically significant difference(P>0.05).Conclusion Acupuncture combined with western medicine in the treatment of LDH of qistagnation and blood stasis type can significantly improve the lumbar function and clinical symptoms of the patients,and improve the muscular performance of the patients'LMM and MM,so as to enhance their quality of life.

Catheter-based percutaneous coronary intervention has become a crucial approach for treating obstructive coronary artery disease and is widely applied in clinical practice.Although the new generation of drug-eluting stents(DES)has significantly reduced the incidence of post-procedur-al restenosis and improved long-term clinical outcomes,in-stent restenosis(ISR)remains one of the key challenges affecting the long-term efficacy of percutaneous coronary intervention.Recent studies have demonstrated that DES still have certain inherent limitations.From the metallic stent platform,drug coating to the polymer carrier,each component may exert varying degrees of biological effects on the vascular intima.Optical coherence tomography(OCT),as a high-resolution intravascular imaging technique,has shown significant value in the mechanism research,etiological diagnosis,and clinical classification of ISR.It can clearly identify the tissue composition and morphological characteristics of ISR,providing a precise basis for the formulation of individualized treatment strategies.This review aimed to systematically search the existing literature,comprehensively review the clinical and patho-logical features of ISR after DES implantation,focus on the OCT-based ISR classification system,and summarize the current treatment strategies and latest advances for ISR.

BackgroundNon-suicidal self-injury （NSSI） behaviors are common among adolescents with depressive disorders， and school bullying is recognized as a major risk factor. Previous research has shown that self-esteem and alexithymia are closely associated with both school bullying and NSSI. However， the mediating roles of self-esteem and alexithymia in the link between school bullying and NSSI are unclear. ObjectiveTo explore the mediating roles of alexithymia and self-esteem in the relationship between school bullying and NSSI behaviors in adolescents with depressive disorders， in order to inform intervention strategies targeting NSSI in this population. MethodsA total of 335 adolescents diagnosed with depressive disorders and treated at the First Psychiatric Hospital of Harbin from July 2023 to October 2024 were enrolled. Assessments included a self-developed demographic questionnaire， Adolescent Non-suicidal Self-injury Assessment Questionnaire-Behavior （ANSAQ-B）， Delaware Bullying Victimization Scale-Student （DBVS-S）， Rosenberg Self-Esteem Scale （RSES）， and 26-item Toronto Alexithymia Scale （TAS-26）. Pearson correlation analysis was used to examine the relationship among variables. Controlling for gender and age at onset of depressive symptoms， mediation analysis was performed using the “mediation” package in R 4.4.2. ResultsScores on DBVS-S and TAS-26 were positively correlated with ANSAQ-B score （r=0.408， 0.417， P<0.01）， while RSES scores were negatively correlated（r=-0.300， P<0.01）. Regression analysis showed that school bullying and alexithymia significantly positively predicted NSSI behaviors （B=0.212， 0.333， P<0.01）， while self-esteem negatively predicted NSSI behaviors （B=-0.368， P<0.01）. Alexithymia was found to mediate the relationship between school bullying and NSSI behaviors， with an indirect effect of 0.040 （95% CI： 0.018~0.069） ，account for 17.17% of the total effect. The indirect effect through self-esteem was not statistically significant （95% CI： -0.004~0.069）. ConclusionExposure to school bullying and high levels of alexithymia are important predictors of NSSI behavior in adolescents with depressive disorders， and school bullying may indirectly influence NSSI behavior through alexithymia. ［Funded by Scientific Research Project of Health Commition of Heilongjiang Province，（number， 20230303090154］

Depression (Dep) is one of the most common concomitant symptoms of Parkinson's disease (PD), but there is a lack of detailed pathologic evidence for the occurrence of PD-Dep. Currently, the management of symptoms from both conditions using conventional pharmacological interventions remains a formidable task. In this study, we found impaired activation of extracellular signal-related kinase (ERK), reduced levels of transcription and translation, and decreased expression of brain-derived neurotrophic factor (BDNF) in the medial prefrontal cortex (mPFC) of PD-Dep rats. We demonstrated that the abnormal phosphorylation of α-synuclein (pS129) induced tropomyosin-related kinase receptor type B (TrkB) retention at the neuronal cell membrane, leading to BDNF/TrkB signaling dysfunction. We chose SEW2871 as an ameliorator to upregulate ERK phosphorylation. The results showed that PD-Dep rats exhibited improvement in behavioral manifestations of PD and depression. In addition, a reduction in pS129 was accompanied by a restoration of the function of the BDNF/ERK signaling loop in the mPFC of PD-Dep rats.

Objective:To investigate the expression and methylation status of the SALL4 gene in placental tissues of fetal growth restriction (FGR) and its effects on trophoblast cell proliferation, migration, and invasion. Methods:Placental tissues were collected from 20 full-term FGR patients and 20 healthy term controls who underwent regular prenatal examination and cesarean section at the Third Affiliated Hospital, Zhengzhou University between July 2023 and February 2024. SALL4 mRNA and protein expression were analyzed by quantitative real-time polymerase chain reaction (qRT-PCR) and Western blot. Methylation specific polymerase china reaction (MSP) assessed promoter methylation levels. HTR8/SVneo cells were transfected with SALL4-targeting small interfering RNA (si-SALL4) or negative control small interfering RNA (si-NC). HTR8/SVneo cells were treated with the demethylating agent 5-aza-2′-deoxycytidine (5-Aza-dC) to inhibit gene methylation (5-Aza-dC group) or with 10% RPMI-1640 medium as a vehicle control. Transfection efficiency (for siRNA) and the efficacy of 5-Aza-dC-induced demethylation were assessed by qRT-PCR and Western blot. The functional effects of SALL4 knockdown and methylation inhibition on trophoblast cells were evaluated using proliferation assays, scratch wound healing assays, and Transwell invasion assays. Statistical analyses included independent t-tests and Chi-square test. Results:(1) Human tissues: FGR placentas showed lower SALL4 mRNA (0.802±0.194 vs. 1.015±0.186, t=3.55) and protein expression (0.445±0.114 vs. 0.701±0.113, t=3.19), alongside higher methylation rates of SALL4 [80% (16/20) vs. 15% (3/20), χ2=14.44] compared to controls (all P<0.05). (2) In vitro: si-SALL4 transfection reduced HTR8/SVneo proliferation (OD450 at 48 h: 0.653±0.021 vs. 0.827±0.040, t=6.60), migration [healing rate at 48 h: (24.317±2.637)% vs. (49.327±1.961)%, t=13.18], and invasion [counted invaded cells: (133.000±6.557) vs. (272.667±18.009) cells, t=12.62] versus si-NC (all P<0.05). Conversely, 5-Aza-dC treatment increased HTR8/SVneo proliferation (0.917±0.042 vs. 0.783±0.031, t=－4.47), migration [(71.097±3.354)% vs. (51.632±2.877)%, t=－7.63], and invasion [(384.000±12.166) vs. (202.833±7.095) cells, t=－13.69] versus vehicle control (all P<0.05). Conclusions:Hypermethylation of the SALL4 promoter in FGR placentas suppresses its expression, impairing trophoblast cell function. Demethylation restores SALL4 expression and enhances cellular proliferation, migration, and invasion, involving in the occurrence and development of FGR disease.

Objective:To analyze the hepatic tissue inflammatory activity and influencing factors in HBeAg-positive patients during normal alanine aminotransferase (ALT) and indeterminate phases so as to provide a basis for evaluating the disease condition.Methods:Patients with HBeAg-positive with normal ALT and HBV DNA levels below 2 × 10 7 IU/ml from January 2017 to December 2021 were selected as the study subjects. A histopathologic liver test was performed on these patients. Age, gender, time of HBV infection, liver function, HBsAg level, HBV DNA load, genotype, portal vein inner diameter, splenic vein inner diameter, splenic thickness, and others of the patients were collected. Significant influencing factors of inflammation were analyzed in patients using logistic regression analysis, and its effectiveness was evaluated using receiver operating characteristic (ROC) curves. Results:Of the 178 cases, there were 0 cases of inflammation in G0, 52 cases in G1, 101 cases in G2, 24 cases in G3, and one case in G4. 126 cases (70.8%) had inflammatory activity ≥ G2. Infection time ( Z=-7.138, P<0.001), γ-glutamyltransferase ( t ?=-2.940, P=0.004), aspartate aminotransferase ( t ?=-2.749, P=0.007), ALT ( t ?=-2.153, P=0.033), HBV DNA level ( t ?=-4.771, P=0.010) and portal vein inner diameter ( t ?=-4.771, P<0.001) between the ≥G2 group and < G2 group were statistically significantly different. A logistic regression analysis showed that significant inflammation in liver tissue was independently correlated with infection time [odds ratio (OR)=1.437, 95% confidence interval ( CI): 1.267-1.630; P<0.001)] and portal vein inner diameter ( OR=2.738, 95% CI: 1.641, 4.570; P<0.001). The area under the curve (AUROC), specificity, and sensitivity for infection time and portal vein inner diameter were 0.84, 0.71, 0.87, 0.72, 0.40, and 0.95, respectively. Conclusion:A considerable proportion of HBeAg-positive patients have inflammation grade ≥G2 during normal ALT and indeterminate phases, pointing to the need for antiviral therapy. Additionally, inflammatory activity has a close association with the time of infection and portal vein inner diameter.

The pulmonary complications associated with inflammatory bowel disease (IBD) predominantly affect the airways, with bronchiectasis being the most frequently observed condition. Concurrently, there is a notable increase in the prevalence of IBD among individuals with pulmonary disorders. This trend suggests a possible reciprocal relationship between IBD and pulmonary diseases, indicative of the "gut-lung axis" at play. The etiology of bronchiectasis in the context of IBD remains elusive, and there is a dearth of effective clinical tools for monitoring and prevention. This paper delves into the pathogenesis of IBD-related bronchiectasis, with a particular emphasis on the role of the gut-lung axis in this scenario. It scrutinizes the impact of immune responses and dysbiosis of the microbiome on the chronic inflammation observed in both the intestinal tract and the respiratory system.
