BACKGROUND:Traditional surgery for lumbar disc herniation involves extensive excision of tissue surrounding the nerve for decompression and removal of protruding lumbar intervertebral discs,which poses various risks and complications such as nerve damage causing paralysis,lumbar instability,herniation recurrence,intervertebral space infection,and adjacent vertebral diseases. OBJECTIVE:To propose the symmetrically adduction of lumbar decompression induced resorption of herniated nucleus pulpous technique for lumbar spine symmetrically decompression,showing the induced resorption of herniated nucleus pulpous phenomenon and early clinical efficacy,and then analyze its decompression mechanism. METHODS:214 patients with lumbar disc herniation at Department of Orthopedics,First Affiliated Hospital of Zhengzhou University from March 2021 to May 2023 were enrolled in this study.Among them,81 patients received conservative treatment as the control group,and 133 patients received symmetrically adduction of lumbar decompression induced resorption of herniated nucleus pulpous treatment as the trial group.Before surgery,immediately after surgery(7-14 days),and early after surgery(over 1 year),MRI images were used to measure the volume changes of lumbar disc herniation.CT images were used to measure the posterior displacement distance of the lumbar spinous process ligament complex,as well as the width and height of the lateral recess.Japanese Orthopaedic Association scores were used to evaluate the patient's neurological function recovery. RESULTS AND CONCLUSION:(1)Control group:81 patients with lumbar disc herniation were treated conservatively,with a total of 171 herniated lumbar discs.The average follow-up time was(22.7±23.1)months.The first and second MRI measurements of 171 herniated lumbar discs showed herniated lumbar disc volumes of(551.6±257.9)mm3 and(792.2±330.4)mm3,respectively,with an average volume increase rate of(53.2±44.4)%,showing statistically significant differences(P<0.001).Out of 171 herniated lumbar discs,4 experienced natural shrinkage,with an absorption ratio of 2.3%(4/171)and an absorption rate of(24.5±9.9)%.(2)Trial group:133 patients with lumbar disc herniation had a total of 285 herniated lumbar discs.(1)Immediately after surgery:All patients were followed up immediately after surgery.229 out of 285 herniated lumbar discs experienced retraction,with an absorption ratio of 80.3%(229/285)and an average absorption rate of(21.5±20.9)%,with significant and complete absorption accounting for 6.5%.There were a total of 70 herniated lumbar discs in the upper lumbar spine,with an absorption ratio of 85.7%(60/70),an average absorption rate of(23.1±19.5)%,and a maximum absorption rate of 86.6%.There were 215 herniated lumbar discs in the lower lumbar spine,with an absorption ratio of 78.6%(169/215),an average absorption rate of(21.0±21.3)%,and a maximum absorption rate of 83.2%.Significant and complete absorption of the upper and lower lumbar vertebrae accounted for 5.7%and 6.5%,respectively,with no statistically significant difference(P>0.05).The average distance of posterior displacement of the spinous process ligament complex immediately after surgery was(5.2±2.8)mm.There were no significant differences in the width and height of the left and right lateral recess before and immediately after surgery(P>0.05).The Japanese Orthopaedic Association score immediately after surgery increased from(10.1±3.4)before surgery to(17.0±4.8),and the immediate effective rate after surgery reached 95.6%.(2)Early postoperative period:Among them,46 patients completed the early postoperative follow-up.There were 101 herniated lumbar discs,with an absorption ratio of 94%(95/101)and an average absorption rate of(36.9±23.7)%.Significant and complete absorption accounted for 30.6%,with a maximum absorption rate of 100%.Out of 101 herniated lumbar discs,3 remained unchanged in volume,with a volume invariance rate of 2.97%(3/101).Out of 101 herniated lumbar discs,3 had an increased volume of herniated lumbar discs,with an increase ratio of 2.97%(3/101)and an increase rate of(18.5±18.4)%.The Japanese Orthopaedic Association score increased from preoperative(9.3±5.1)to(23.5±4.0),with an excellent and good rate of 93.4%.(3)The early postoperative lumbar disc herniation absorption ratios of the control group and trial group were 2.3%and 85.9%,respectively,with statistically significant differences(P<0.001).(4)Complications:There were two cases of incision exudation and delayed healing in the trial group.After conservative treatment such as dressing change,no nerve injury or death occurred in the incision healing,and no cases underwent a second surgery.(5)It is concluded that symmetrically adduction of lumbar decompression induced resorption of herniated nucleus pulpous is a new method for treating lumbar disc herniation that can avoid extensive excision of the"ring"nerve and achieve satisfactory early clinical efficacy.It does not damage the lumbar facet joints or alter the basic anatomical structure of the lateral recess,fully preserves the herniated lumbar discs,and can induce significant or even complete induced resorption of herniated nucleus pulpous.Symmetrically adduction of lumbar decompression induced resorption of herniated nucleus pulpous provides a new basis and method for the clinical treatment of lumbar disc herniation.

Objective: To investigate the mechanism of action of Wuzi Yanzong pill (WYP) in rats with oligoasthenozoospermia (OAZ) via metabolomics and to provide a possible basis for improving this WYP-based treatment. Methods: A rat model of OAZ was established by treating male Sprague–Dawley rats with glucosides from Tripterygium wilfordii Hook. F. Seventy-two rats were randomly divided into six groups: control, L-carnitine (positive control), model, and low-, medium-, and high-dose WYP groups. Rats in the experimental groups were treated with WYP for 4 weeks. At the end of the treatment period, sperm cell quality (density, motility, and viability) was assessed using a semen analysis system, mitochondrial membrane potential (MMP) was assessed using flow cytometry, and testicular injury was assessed using hematoxylin and eosin staining to validate the therapeutic effect of WYP in OAZ. Further, serum metabolomics-based analysis was performed using high-performance liquid chromatography-mass spectrometry to identify differential metabolic pathways and possible mechanisms of action of WYP in OAZ treatment. Results: A rat model of OAZ was considered successfully-established after comparing the quality of spermatozoa in the model group to that in the control group. WYP-M and WYP-H treatments significantly improved sperm cell density, motility, and viability compared with those in the model group (all P < .05). Compared with the model group, both WYP-M and WYP-H treatments increased MMP values (P = .006 and P = .021 respectively), while there was no significant difference in the L-carnitine group. L-carnitine and WYP administration reversed damage to the testes to varying degrees compared with that in the model group. Further, 44 differential metabolites and four metabolic pathways, especially autophagy pathway, related to OAZ were identified via metabolomics. Conclusions WYP improves sperm cell quality and MMP in OAZ primarily via autophagy regulation. These findings can be employed to improve the efficacy of WYP in humans.

Objective To explore the mechanism of microRNA(miRNA)-365a-3p affecting the function of vascular endothelial cells involved in the pathogenesis of preeclampsia(PE).Methods Primary human umbilical vein endothelial cells(HUVECs)were set as a NC group(transfected miR-365a-3p NC),a mimics group(trans-fected miR-365a-3p mimics)and a inhibitor group(transfected miR-365a-3p inhibitor).Logarithmic HUVECs cells were set as the blank group.The cell proliferation,migration and angiogenesis in each group were detected.Dual luciferin assay verified the targeting relationship between miR-365a-3p and downstream gene.The protein expressions of TGF-β1,Smad4 and Smad7 in each group were detected.Results Compared with the blank group and the NC group,the absorbance value and mobility of 24,48 and 72 h were decreased(P＜0.05),the number of tubular structures per field were decreased in the mimics group(P＜0.05),the absorbance value and mobility of 24,48 and 72 h were increased(P＜0.05),and the number of tubular structures per field were increased in the inhibitor group(P＜0.05).Dual luciferin assay showed that Smad7 was a target gene of miR-365a-3p.Compared with the blank group and the NC group,the protein expressions of TGF-β1 and Smad4 in the mimics group were increased(P＜0.05),while the protein expression of Smad7 was decreased(P＜0.05).The protein expression levels of TGF-β1 and Smad4 in the inhibitor group were decreased(P＜0.05),while the protein expression levels of Smad7 were increased(P＜0.05).Conclusion miR-365a-3p may affect the function of vascular endothelial cells by regulating the downstream TGF-β signaling pathway,and thus participate in the pathogenesis of PE.

Objective:To explore the gene mutation characteristics and the relationship between gene mutations and long-term prognosis in clinical stage ⅠA lung adenocarcinoma patients.Methods:A retrospective analysis was conducted on 63 clinical stage ⅠA lung adenocarcinoma patients who underwent surgical resection at the Cancer Hospital of the Chinese Academy of Medical Sciences from January 2007 to October 2012, with documented postoperative recurrence or metastasis, as well as those who had a follow-up duration of 10 years or more without recurrence or metastasis. Whole exome sequencing (WES) technology was used to analyze the gene mutation profiles in tumor tissues and univariate and multivariate Cox regression analysis were used to clarify the influencing factors for patient prognosis.Results:After long term follow-up, 13 out of the 63 patients (21%) experienced recurrence or metastasis. WES technology analysis revealed that the most common tumor related gene mutations occurred in epidermal growth factor receptor (EGFR), with a mutation rate of 65.1% (41/63), followed by tumor protein p53 (TP53), fatatypical cadherin 1 (FAT1), low density lipoprotein receptor-related protein 1B (LRP1B), mechanistic target of rapamycin (MTOR), phosphatidylinositol-4,5-bisphosphate 3-kinase catalytic subunit gamma (PIK3CG), and SWI/SNF related, matrix associated, actin dependent regulator of chromatin, subfamily A, member 4 (SMARCA4), with mutation rates of 30.2% (19/63), 20.6% (13/63), 15.9% (10/63), 15.9% (10/63), 15.9% (10/63), and 15.9% (10/63), respectively. Multivariate Cox regression analysis showed that PIK3CG mutations ( HR=21.52, 95% CI: 3.19-145.01),smoothened (SMO) mutations ( HR=35.28, 95% CI: 3.12-398.39), catenin beta 1 (CTNNB1) mutations ( HR=332.86, 95% CI: 15.76-7 029.05), colony stimulating factor 1 receptor (CSF1R) mutations ( HR=8 109.60, 95% CI: 114.19-575 955.17), and v-Raf murine sarcoma viral oncogene homolog B (BRAF) mutations ( HR=23.65, 95% CI: 1.86-300.43) were independent risk factors affecting the prognosis of clinical stage ⅠA lung adenocarcinoma patients. Conclusions:PIK3CG, SMO, CTNNB1, CSF1R, BRAF gene mutations are closely related to long-term recurrence or metastasis in clinical stage ⅠA lung adenocarcinoma. Patients with these gene mutations should be given closer clinical attention.

Objective To explore the risk factors for renal anemia in hemodialysis patients with end-stage kidney disease (ESKD). Methods A total of 48 ESKD patients undergoing hemodialysis in our hospital from December 2021 to December 2022 were selected as study objects. They were divided into renal anemia group (86 cases) and non-anemia group (62 cases) based on hemoglobin (Hb) levels and diagnostic criteria for renal anemia. Clinical data between the two groups were compared. Random forest algorithm and multivariate Logistic regression analysis were used to screen for factors influencing renal anemia, and a multivariate Logistic regression model was established. Cross-validation was also employed to verify the stability of the model. A risk stratification system was developed, and patients were stratified based on cut-off values obtained from X-Tile software. The areas under the receiver operating characteristic (ROC) curves were used to evaluate the discrimination ability of the multivariate Logistic regression model and the risk stratification system. Results Among 148 ESKD patients, the incidence of renal anemia was 58.11% (86/148). Hypertension, increased neutrophil-to-lymphocyte ratio (NLR), elevated C-reactive protein (CRP), increased serum ferritin (SF), and elevated intact parathyroid hormone (iPTH) were identified as risk factors for renal anemia (P < 0.05). Administration of α-calcidol, increased erythropoietin (EPO), elevated triglyceride (TG), and increased serum albumin (ALB) were protective factors (P < 0.05). The goodness-of-fit test for the multivariate Logistic regression model showed a Nagelkerke R2 of 0.593. Based on the cut-off values for risk scores obtained from X-Tile software, patients were stratified into low-risk group (< 4 points, 29 cases), medium-risk group (4 to < 7 points, 64 cases), and high-risk group (≥7 points, 55 cases), with renal anemia incidence rates of 24.14%, 57.81%, and 76.36%, respectively. The difference in renal anemia incidence rates among the three groups was statistically significant (P < 0.001). In the training set, the areas under the ROC curves for the multivariate Logistic regression model and the risk stratification system were 0.826 and 0.811, respectively, and were 0.804 and 0.789, respectively in the validation set. Conclusion The occurrence of renal anemia in hemodialysis patients with ESKD is influenced by various factors, including hypertension, NLR, CRP, etc.

Objective:To analyze and verify the expression of ISL1 gene in myocardial infarction, and explore its mechanism of action in myocardial infarction.Methods:By analyzing the chip expression profile data in the GEO database, the expression characteristics of the ISL1 gene in myocardial infarction, as well as the highly co expressed related genes and enriched pathway functions of the ISL1 gene, were identified. Patients with myocardial infarction and their healthy controls were included, and the expression of genes such as ISL1 and GRIN2D was verified using real-time polymerase chain reaction (RT-PCR).Results:The expression level of ISL1 gene in myocardial infarction samples was higher than that in the control group samples. In the GSE59867 and GSE29111 datasets, there are a total of 152, 231, and 329 intersections of the top 2000, top 2500, and top 3000 related genes, respectively. The functional annotation of co-expressed genes revealed that intersection genes were closely related to organ development, matrix protein formation, epithelial cell differentiation, and the activity of related signaling pathways during embryonic development. Finally, in the construction of the ISL1 related ceRNA regulatory network, 12 genes were located in the ISL1 top 2000 related mating set, and together with miRNAs, they participated in the formation of 21 pairs of miRNA-mRNA. And through multiple queues, the key regulatory gene was identified as GRIN2D, which competitively bound to multiple miRNAs with ISL1 and its expression was highly negatively correlated with ISL1 in two independent datassets ( r=-0.52, -0.41). The RT-PCR results showed that the expression levels of miR-128-3p, miR 27a-3p, and miR-27b-3p in the acute myocardial infarction group were lower than those in the control group, while the expression levels of ISL1 and GRIN2D were higher than those in the control group (all P<0.01). Conclusions:ISL1 may play a protective role in myocardial infarction by participating in the formation of matrix proteins, differentiation of epithelial cells, and activity of related signaling pathways.

Objective: To systematically review the associations of physical activity (PA), sedentary behavior (SB) and sleep with obesity, as well as isotemporal substitution effects among behaviors, determined with compositional data analysis methods, to provide a reference for obesity interventions among children and adolescents. Methods: Studies in the CNKI, Wanfang, PubMed, SPORTDiscus, Web of Science and Medline databases were searched from January 1, 2014 to May 1, 2022. Two experienced reviewers independently completed document screening, data extraction and quality assessment. Results: Sixteen articles were included, with a methodological quality score range of 7-12 points. Moderate to vigorous physical activity (MVPA), sleep and obesity were negatively correlated, and substituting other behaviors with MVPA decreased obesity risk. The substitution time ranged from 1.5 min/day to 60 min/day. Light physical activity(LPA) and SB were positively correlated with obesity. Conclusion MVPA is the primary focus of obesity interventions in children and adolescents, and extra 60 min of MVPA per week on the existing level of physical activity may be the minimum necessary to decrease the risk of obesity.
