OBJECTIVE: To evaluate early effectiveness of posterior 180-degree decompression via unilateral biportal endoscopy (UBE) in the treatment of lumbar spinal stenosis (LSS) combined with Michigan State University (MSU)-1 lumbar disc herniation (LDH). METHODS: A retrospective analysis was conducted on clinical data from 33 patients with LSS combined with MSU-1 LDH, who met selection criteria and were treated between March 2022 and January 2024. All patients underwent UBE-assisted 180-degree spinal canal decompression. The cohort comprised 17 males and 16 females, aged 37-82 years (mean, 67.1 years). Preoperative presentations included bilateral lower limbs intermittent claudication and radiating pain, with disease duration ranging from 5 to 13 months (mean, 8.5 months). Affected segments included L _{3, 4} in 4 cases, L _{4, 5} in 28 cases, and L ₅, S ₁ in 1 case. LSS was rated as Schizas grade A in 4 cases, grade B in 5 cases, grade C in 13 cases, and grade D in 11 cases. LDH was categorized as MSU-1A in 24 cases, MSU-1B in 2 cases, and MSU-1AB in 7 cases. Intraoperative parameters (operation time, blood loss) and postoperative hospitalization length were recorded. The visual analogue scale (VAS) score and Oswestry Disability Index (ODI) were used to assess the lower limb pain and functional outcomes after operation. Clinical efficacy was evaluated at last follow-up via modified MacNab criteria. Quantitative radiological assessments included dural sac cross-sectional area (DSCA) measurements and spinal stenosis grading on lumbar MRI. Morphological classification of lumbar canal stenosis was determined according to the Schizas grading, categorized into four grades. RESULTS: The operation time was 60.4-90.8 minutes (mean, 80.3 minutes) and intraoperative blood loss was 13-47 mL (mean, 29.9 mL). The postoperative hospitalization length was 3-5 days (mean, 3.8 days). All patients were followed up 12-16 months (mean, 13.8 months). The VAS score and ODI improved at immediate and 3, 6, and 12 months after operation compared to before operation, and the differences between different time points were significant ( P<0.05). At last follow-up, the clinical efficacy assessed by the modified MacNab criteria were graded as excellent in 23 cases, good in 9 cases, and poor in 1 case, with an excellent and good rate of 96.97%. Postoperative lumbar MRI revealed the significant decompression of the dural sac in 32 cases, with 1 case showing inadequate dural expansion. DSCA measurements confirmed progressive enlargement and stenosis reduction over time. The differences were significant ( P<0.05) before operation, immediately after operation, and at 6 months after operation. At 6 months after operation, Schizas grading of spinal stenosis improved to grade A in 27 cases and grade B in 6 cases. CONCLUSION Posterior 180-degree decompression via UBE is a safe and feasible strategy for treating LSS combined with MSU-1 LDH, achieving effective neural decompression while preserving intervertebral disc integrity.

ObjectiveTo analyze the clinical treatment plan and traditional Chinese medicine （TCM） medication rule of children with primary nephrotic syndrome （PNS） in the First Affiliated Hospital of Henan University of Chinese Medicine. MethodsThe gender and age of children firstly diagnosed with nephrotic syndrome in the pediatric nephrology department of the First Affiliated Hospital of Henan University of Chinese Medicine from November 2019 to December 2022 were collected， and the use of immunosuppressive agents and related frequencies were counted. According to the inclusion and exclusion criteria， an independent TCM prescription database for children with nephrotic syndrome was established. Excel was used to analyze the relevant information of the literature. The frequency counting， association rule analysis， and cluster analysis were carried out on TCM in the prescription， and the high-frequent drugs were analyzed. Results（1） General information： A total of 711 children were included， consisting of 522 males （73.42%） and 189 females （26.58%）. The ratio of male to female was about 2.76∶1. The disease mainly occurred in infants and preschool age， and the average age of onset was （4.74 ± 3.48） years old. （2） Clinical treatment plan and use of immunosuppressive agents： Of the 711 children with PNS， 237 were treated with hormone alone （32.33%）， and 474 （66.67%） received immunosuppressive agents combined with hormones. In the initial treatment， hormone combined with Tacrolimus （TAC） was the preferred treatment （32.91%）. For children with refractory PNS who exhibited poor clinical efficacy， Rituximab （RTX） was mostly used for treatment， with a ratio of up to 23.63%. （3） TCM syndrome and medication rule： In PNS syndrome differentiation， Qi and Yin deficiency was identified as the main syndrome. This involved a total of 477 cases， accounting for 67.09%. Yang deficiency of spleen and kidney was observed in 118 cases， accounting for 16.60%. A total of 711 children were included， of which 706 children were treated with TCM. This involved a total of 706 prescriptions， 226 TCM， and 9 793 frequencies. There were 30 herbs used more than 95 times. The top five TCM were Radix et Rhizoma Glycyrrhizae （81.16%）， Radix Astragali （71.81%）， Poria （68.84%）， Rhizoma Atractylodis Macrocephalae （63.60%）， and Fructus Corni （57.37%）. The drug association rules and network diagram showed that the combination of ''Radix Astragali-Rhizoma Atractylodis Macrocephalae-Poria'' was the closest， and five types of combinations were obtained by cluster analysis. ConclusionIn the diagnosis and treatment of PNS in children， TAC combined with hormones shows good clinical efficacy and high safety. For children with refractory PNS， RTX combined with hormones can be used. TCM medication for PNS should follow the basic principles of strengthening the body and vital Qi and make good use of drugs such as Radix Astragali， Poria， Rhizoma Atractylodis Macrocephalae， and cornus to regulate the Yin and Yang balance and achieve better clinical efficacy.

Objective To investigate the associations between physical health status,refraction and ocular biometrics in school-age children,and further clarify the relation of eyes'refractive status to physical growth and development,so as to provide scientific evidences for myopia prevention and con-trol.Methods A total of 1718 children(977 boys and 741 girls)aged 8-12 years were enrolled in this study.They were collected uncorrected visual acuity,refraction and ocular biometrics,including spherical equivalent,cylindrical equivalent,axial length(AL),corneal refraction(K1,K2)and anteri-or chamber depth(ACD),as well as the AL/CR ratio and spherical equivalent refraction(SER).Moreover,their height,weight and physical fitness level were measured,including speed,strength,flexibility,agility and aerobic endurance.Then all data were analyzed using the Pearson correlation,One-way ANOVA and multiple linear regression model.Results The overall prevalence of myopia was 43.83%,which was higher in girls than in boys(46.96%vs.41.45%).Moreover,the height and weight of school-age children were negatively correlated with SER(P<0.01),but positively correlated with AL,ACD and AL/CR(P<0.01).After controlling the age and gender variables in the multiple linear regression model,it was found that for 10-cm increase in height,SER decreased by 0.013 D(P<0.01),AL extended by 0.022 mm(P<0.01),and ACD increased by 0.002 mm(P<0.05).In addi-tion,for 10-kg increase in the body weight,the AL would be 0.009 mm longer(P<0.05)and ACD 0.002 mm deeper(P<0.05).Moreover,the speed,strength and agility were negatively correlated with SER(P<0.01,P<0.05),but positively correlated with AL,ACD and AL/CR(P<0.01,P<0.05).The maximal oxygen uptake level was positively correlated with SER(P<0.01),and negatively correlated with AL,ACD and AL/CR(P<0.01,P<0.05).After controlling the age and gender variables in the multiple linear regression model,it was found that the children with worse speed quality had shorter AL(-0.043 D,P<0.05).Meanwhile,the better agility was accompanied by the lower SER(-0.003 D,P<0.01),longer AL(+0.002 mm,P<0.05),lighter ACD(+4.812e-4 mm,P<0.05),and higher AL/CR(+2.446e-4,P<0.05).Conclusion With variables of age and gender controlled,the height,weight,and the speed and agility quality are highly associated with eyes'refractive status among chil-dren aged 8-12 years old.It is suggested that the human body may have a coordination mechanism to regulate the development of the body stature,physical fitness and ocular biometrics in the early child-hood,which should be considered in their myopia prevention and control.

Knee osteoarthritis(KOA)is a common musculoskeletal disease,and ferroptosis is a new type of programmed cell death involving iron ions.This paper summarized the relationship between the pathological changes of ferroptosis and the onset of KOA,and reviewed the progress of traditional Chinese medicine(TCM)intervention in KOA based on the pathological changes of ferroptosis.The pathological changes of ferroptosis are mainly related to the imbalance of amino acid antioxidant system,iron metabolism disorder and lipid peroxide accumulation.The cystine/glutamate antiporter(System XC-),glutathione(GSH)and glutathione peroxidase 4(GPX4)are the core targets for regulating ferroptosis,involving the main signaling pathways for studying the TCM intervention of KOA via ferroptosis.Single herbs such as Drynariae Rhizoma,Scutellariae Barbatae Herba,Epimedii Folium,Astragali Radix,Ligustri Lucidi Fructus,and Achyranthis Bidentatae Radix,and multi-herb formulae such as Duhuo Jisheng Decoction and Yougui Pills,can inhibit the ferroptosis of chondrocytes through multiple targets and multiple pathways,thus treating KOA.The research of the TCM intervention on the ferroptosis of chondrocytes and its associated signaling pathways can provides a novel approach for expanding the TCM therapy of KOA.

OBJECTIVES: To investigate the inhibitory effect of Danshen Injection on endothelial-mesenchymal transition (EndMT) induced by peritoneal dialysis fluid in HMrSV5 cells and the role of the TGF‑β/Smad signaling pathway in mediating this effect. METHODS: HMrSV5 cells cultured in 40% peritoneal dialysis solution for 72 h to induce EndMT were treated with 0.05%, 0.1% and 0.5% Danshen Injection. CCK-8 assay was used to assess the changes in viability of the treated cells, and the levels of interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), transforming growth factor-β (TGF-β), and vascular endothelial growth factor (VEGF) in the cell supernatant were detected using ELISA; Western blotting was performed to detect the protein expressions of E-cadherin, α-smooth muscle actin (α-SMA), p-Smad 2/3, and Smad 7 in the cells. RESULTS: Culture in 40% peritoneal dialysis fluid for 72 induced significant EndMT in HMrSV5 cells, which exhibited obviously lowered cell viability. Danshen Injection within the concentration range of 0.025%-1.5% did not significantly affect the viability of the cells. Exposure of HMrSV5 cells to peritoneal dialysis fluid for 72 h significantly increased the production of IL-6, TNF‑α, TGF‑β and VEGF, upregulated the protein expressions of α‑SMA and p-Smad 2/3, and lowered the expressions of E-cadherin and Smad7 proteins. Treatment of the exposed cells with Danshen injection significantly increased cell viability and cellular expressions of E-cadherin and Smad 7 proteins and reduced the production of IL-6, TNF-α, TGF-β and VEGF and the protein expressions of α‑SMA and p-Smad 2/3. CONCLUSIONS Danshen Injection can suppress peritoneal dialysis fluid-induced EndMT in HMrSV5 cells possibly by regulating the TGF-β/Smad signaling pathway.

Objective:In this study, we aimed to compare the short-term safety of two digestive tract reconstruction techniques, laparoscopic total abdominal overlap anastomosis and laparoscopic-assisted end-to-side anastomosis, following radical resection of Siewert Type II adenocarcinoma of the esophagogastric junction.Methods:In this retrospective cohort study, we analyzed relevant clinical data of 139 patients who had undergone radical surgery for Siewert Type II esophagogastric junction adenocarcinoma. These included 89 patients treated at the First Affiliated Hospital of Air Force Medical University from November 2021 to July 2023, 36 patients treated at the First Affiliated Hospital of Xi'an Jiaotong University from December 2020 to June 2021, and 14 patients treated at the Yuncheng Central Hospital in Shanxi Province from September 2021 to November 2022. The group consisted of 107 men (77.0%) and 32 women (23.0%) of mean age 62.5±9.3 years. Forty-eight patients underwent laparoscopic total abdominal overlap anastomosis (overlap group), and 91 laparoscopic-assisted end-to-side anastomosis (end-to-side group). Clinical data, surgical information, pathological findings, postoperative recovery, and related complications were compared between the two groups.Results:There were no significant differences in general clinical data between the overlap and end-to-side anastomosis groups (all P>0.05), indicating comparability. There was no significant difference in operation time (267.2±60.1 minutes vs. 262.8±70.6 minutes, t=0.370, P=0.712). However, the intraoperative blood loss in the overlap group (100 [50, 100] mL) was significantly lower compared to the end-to-side group (100[50, 175] mL, Z=2.776, P=0.005). Compared to the end-to-side group, longer distances between the tumor and distal resection margin proximal(1.7±1.0 cm vs. 1.3±0.9 cm, t=2.487, P=0.014) and the tumor and distal resection margin (9.5±2.9 cm vs. 7.9±3.5 cm, t=2.667, P=0.009) were achieved in the overlap group. Compared with the end-to-side group, the overlap group achieved significantly earlier postoperative ambulation (1.0 [1.0, 2.0] days vs. 2.0 [1.0, 3.0] days, Z=3.117, P=0.002), earlier time to first drink (4.7±2.6 days vs. 6.2±3.0 days, t=2.851, P=0.005), and earlier time to first meal (6.0±2.7 days vs. 7.1±3.0 days, t=2.170, P=0.032). However, the hospitalization costs were higher in the overlap group (113, 105.5±37, 766.3) yuan vs. (97, 250.2±27, 746.9) yuan; this difference is significant ( t=2.818, P=0.006). There were no significant differences between the two groups in postoperative hospital stay, total number of lymph nodes cleared, or time to first postoperative flatus (all P>0.05). The incidence of surgery-related complications was 22.9%(11/48) in the overlap group and 19.8% (18/91) in the end-to-side group; this difference is not significant (χ2=0.187, P=0.831). Further comparison of complications using the Clavien-Dindo classification also showed no significant differences ( Z=0.406, P=0.685). Conclusions:Both laparoscopic total abdominal overlap anastomosis and laparoscopic-assisted end-to-side anastomosis are feasible for radical surgery for Siewert Type II esophagogastric junction adenocarcinoma. Laparoscopic total abdominal overlap anastomosis achieves longer proximal and distal resection margins and better postoperative recovery; however, end-to-side anastomosis is more cost-effective.
