ObjectiveTo observe the effect of healthy side tilt training on balance function in patients with Pusher syndrome (PS) after stroke. MethodsFrom February, 2021 to November, 2023, 40 patients with PS after stroke in People's Hospital of Bayingolin Mongolian Autonomous Prefecture were selected. They were divided into control group (n = 20) and experimental group (n = 20) in accordance with the order of the patients' admission. The control group received comprehensive training for paralyzed limbs combined with sitting balance training, and the experimental group received comprehensive training for paralyzed limbs combined with healthy side tilt training, for three weeks. They were assessed with Burke Lateropulsion Scale (BLS), Fugl-Meyer Assessment-Balance (FMA-B) and modified Barthel Index (MBI) before and after treatment. ResultsAfter treatment, BLS score significantly decreased in both groups (t > 12.603, P < 0.001), and was lower in the experimental group than in the control group (t = -2.559, P < 0.05). The scores of FMA-B and MBI were significantly increased in both groups (|Z| > 3.941, |t| > 12.082, P < 0.001), and FMA-B score was higher in experimental group than in the control group (Z = -2.538, P < 0.05). ConclusionComprehensive training for paralyzed limbs combined with healthy side tilt training can effectively improve the balance function and postural control of patients with PS after stroke, and improve the activities of daily living.

Objective To explore the clinical characteristics of patients with diffuse large B-cell lymphoma (DLBCL) accompanied with KMT2D gene mutation and the impact of its co-mutated genes on prognosis. Methods Clinical data of 155 newly diagnosed DLBCL patients were obtained. The second-generation sequencing method was used to detect 475 hotspot genes, including KMT2D mutation. Patients were divided into the KMT2D mutation group and KMT2D wild-type group based on the presence or absence of KMT2D gene mutation. Clinical characteristics, differences in co-mutated genes, and survival differences between the two groups were compared. Results The frequency of KMT2D mutation was 31%, which is predominantly observed in elderly patients (P=0.07) and less in the double-expressor phenotype (P=0.07). Compared with the KMT2D wild-type group, KMT2D gene mutation was associated with higher co-mutation rates of CDKN2A (OR=2.82, P=0.01) and BCL2 (OR=3.84, P=0.016), while being mutually exclusive with MYC gene mutation (OR=0.11, P=0.013). In univariate survival analysis, no statistically significant difference in overall survival (OS) was found between the KMT2D mutation group and the wild-type group (P=0.54). Further analysis of the prognostic significance of KMT2D with other gene mutations indicated that patients with KMT2D^mutBTG2^mut had poorer OS than those with KMT2D^wt BTG2^mut (P=0.07) and KMT2D^wt BTG2^wt (P=0.05). On the contrary, patients with KMT2D^mut CD79B^mut had better OS than those with KMT2D^mut CD79B^wt (P=0.09), with no prognostic impact observed for other co-mutated genes. Multivariate Cox regression analysis revealed that Ann Arbor stages Ⅲ and Ⅳ (HR=2.751, 95%CI: 1.169-6.472, P=0.02), elevated LDH levels (HR=2.461, 95%CI: 1.396-4.337, P=0.002), Ki-67 index>80% (HR=1.875, 95%CI: 1.066-3.299, P=0.029), and KMT2D^mutBTG2^mut(HR=4.566, 95%CI: 1.348-15.471, P=0.015) were independent risk factors for OS in patients with DLBCL (P<0.05). Conclusion DLBCL patients with KMT2D mutation often have multiple gene mutations, among which patients with a co-mutated BTG2 gene have poor prognosis.

BackgroundIt has been shown that academic procrastination， cognitive emotion regulation strategies， anxiety and mobile phone dependence are closely related， but the detailed mechanism by which academic procrastination contributes to mobile phone dependence remains largely unclear and mediation analysis is currently lacking. ObjectiveTo explore the mediation role of cognitive emotion regulation strategies and anxiety in the relationship between academic procrastination and mobile phone dependence among college students， so as to provide references for the prevention and intervention of college students' mobile phone dependence. MethodsIn March 2023， 474 students from Xinjiang Normal University were selected by random sampling technique， and Mobile Phone Addiction Index （MPAI）， Procrastination Assessment Scale-Students （PASS）， Beck Anxiety Inventory （BAI） and Cognitive Emotion Regulation Questionnaire-Chinese version （CERQ-C） were used to conduct the survey. Pearson correlation analysis was adopted to examine the correlation among all variables， and Process 3.5 macro program was utilized to determine the mediation effect of cognitive emotion regulation strategies and anxiety on the relationship between academic procrastination and mobile phone dependence among college students. Results①PASS scores were positively correlated with the scores on CERQ-C negative cognitive emotion regulation strategy， BAI and MPAI （r=0.374， 0.229， 0.661， P<0.01）， CERQ-C negative cognitive emotion regulation strategy scores were positively correlated with BAI and MPAI scores （r=0.372， 0.498， P<0.01）， and BAI scores were positively correlated with MPAI scores （r=0.340， P<0.01）. ② Both negative cognitive emotion regulation strategy and anxiety exerted an mediation effect on the relationship between academic procrastination and mobile phone dependence among college students， with an effect value of 0.094 （95% CI： 0.056~0.137） and 0.013 （95% CI： 0.001~0.029）， and a chained mediation effect of negative cognitive emotion regulation strategy and anxiety on the relationship between academic procrastination and mobile phone dependence among college students was also documented， with an effect value of 0.015 （95% CI： 0.006~0.026）. ConclusionAcademic procrastination is proved to be effective in predicting college students' mobile phone dependence both directly and indirectly through either separate or chained mediation of negative cognitive emotion regulation strategy and anxiety. ［Funded by Social-Science Fund Project in Xinjiang （number， 2023CSH068）； Scientific Research Projects of Universities in Xinjiang Uygur Autonomous Region （number， XJEDU2023P081）］

OBJECTIVE To investigate the mechanism of gossypol acetic acid （GAA） in the treatment of uterine fibroids. METHODS Human leiomyoma cells SK-UT-1 were selected as objects to investigate the effects of different concentrations （5， 10， 20， 40， 80， 160 μmol/L） of GAA on the activities of cell proliferation. 4D-DIA proteomic detection and bioinformatics analysis were carried out to screen differential proteins. Gene ontology （GO） analysis and Kyoto Encyclopedia of Genes and Genomes （KEGG） signaling pathway analysis were performed. The expressions of top 3 proteins [N-myc downstream regulated gene 1 （NDRG1）， epidermal growth factor receptor feedback inhibitor 1 （ERRFI1）， CXC chemokine ligand 3 （CXCL3）] with differential fold changes in SK-UT-1 cells were determined. RESULTS 10-160 μmol/L GAA could significantly reduce the survival rate of SK- UT-1 cells （P＜0.05）. Proteomics results showed that a total of 921 differentially expressed proteins were obtained， including 254 up-regulated proteins and 667 down-regulated proteins. The differentially expressed proteins were mainly distributed in mitochondria， nucleus， extracellular matrix， etc. Bioinformatics results showed that differentially expressed proteins were mainly involved in signaling pathways such as PI3K/AKT （phosphoinositide 3-kinase/protein kinase B）， MAPK （mitogen-activated protein kinase）， TNF （tumor necrosis factor）， etc.， which mainly involved cell apoptosis， aging， and movement. GAA significantly decreased protein expressions of NDRG1 and CXCL3 （P＜0.05）， but increased protein expression of ERRFI1 （P＜0.05）. CONCLUSIONS The improvement effect of GAA on uterine fibroids may involve signaling pathways such as PI3K/AKT， MAPK， TNF， etc. It can improve the occurrence and development of uterine fibroids by downregulating the expressions of NDRG1 and CXCL3 proteins， upregulating the expression of ERRFI1 protein， and affecting the proliferation and apoptosis of uterine fibroid cells.

AIM: To compare the changes in corneal epithelial thickness(CET)after small incision lenticule extraction(SMILE)and femtosecond laser-assisted in situ keratomileusis(FS-LASIK).METHODS: A total of 187 patients(187 eyes)who underwent either SMILE or FS-LASIK at Urumqi Aier Eye Hospital between December 2022 and November 2023 were collected. The patients were divided into SMILE group and FS-LASIK group according to surgical methods. The CET of the patients was measured by optical coherence tomography(OCT)system before surgery and at 1 wk, 1, 3, and 6 mo postoperatively.RESULTS: Changes in corneal epithelial thickness(△CET)in the central, paracentral, and mid-peripheral regions were compared at 6 mo postoperatively. The SMILE group was characterized by the most significant thickening in the central area and the least thickening in the mid-peripheral area; while the FS-LASIK group was characterized by the most significant thickening in the paracentral area and the least thickening in the mid-peripheral region. At 1 wk, 1, 3, and 6 mo postoperatively, within the 0-7 mm corneal area, the △CET for both the SMILE and FS-LASIK groups was correlated with the preoperative spherical equivalent.CONCLUSION: Within 6 mo postoperatively, both SMILE and FS-LASIK showed a similar trend in epithelial thickening but with distinct characteristics. The change in corneal epithelial thickness for both procedures was positively correlated with the preoperative diopter.

AIM: To observe the changes of corneal densitometry(CD)and higher-order aberrations after small incision lenticule extraction(SMILE), and to explore their correlations and influencing factors.METHODS: Prospective study. A total of 62 high-degree myopia and compound myopic astigmatism patients(62 eyes)who underwent SMILE in Urumqi Aier Eye Hospital from December 2022 to November 2023 were collected. The CD, root mean square of corneal higher-order aberrations(RMS HOA), spherical aberration, vertical coma, horizontal coma, and corneal epithelial thickness(CET)of the patients were measured before surgery, and at 1 d, 1 wk, 1, 3, and 6 mo after surgery, respectively.RESULTS:There were 4 patients lost to follow-up during the period, all due to failure to attend scheduled reexaminations. The number of complete and valid cases was 58 eyes. The CD in the central and paracentral regions of the anterior, middle, and total layer of the cornea increased significantly on the first day after surgery(all P<0.003). At 6 mo after surgery, there was a slight but statistically significant decrease in the CD of the central and paracentral regions of the anterior and the total anterior layer(all P<0.003). Compared with the preoperative baseline values, the RMS HOA, spherical aberration, and vertical coma significantly increased at 6 mo after surgery(all P<0.003), while the change in horizontal coma was not statistically significant. Compared with the preoperative baseline values, the CET in the central, paracentral, and peripheral regions of the cornea, as well as the total average CET in the 0-7 mm range of the cornea increased at 6 mo after surgery(all P<0.003). At 1 d after surgery, CD of the anterior layer and total layer in the central region of the cornea were positively correlated with the CET in the central region(rs=0.327, rs=0.250, all P<0.05). At 6 mo after the surgery, the CD of the middle layer and posterior layer in the central corneal region were negatively correlated with the preoperative spherical equivalent and the change of RMS HOA(all P<0.05).CONCLUSION:The anterior CD decreases at 6 mo after SMILE for high myopia correction, and there is a certain correlation between the changes in CD and some clinical parameters.

Five compounds were isolated and purified from the water extract of Elaeagnus oxycarpa Schlechtend leaf by multi-dimensional reversed-phase preparative liquid chromatographic system based on the separation and enrichment model. Their structures were identified by spectral analysis such as NMR, MS, UV, IR and by comparison with literature information as 2,4(1H,3H)-pyrimidinedione (1), elaeagnussugarester B (2), elaeagnussugarester A (3), elaeagnussugarester C (4), gallic acid (5). Compounds 2-4 are new compounds, compound 1 was isolated from Elaeagnus oxycarpa Schlechtend for the first time. The antioxidant and anti-tyrosinase activities of these compounds were evaluated by using the 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical method, the 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) free radical method, the potassium ferricyanide reduction method and the colorimetric method with L-tyrosine as substrate. The results showed that compounds 2-5 have good antioxidant activities and inhibitory effect on tyrosinase. Compound 4 exhibited the most strong antioxidant activities, with IC₅₀ = 3.59 ± 0.06 μmol·L^-1 for DPPH free radical scavenging ability, IC₅₀ = 10.04 ± 0.20 μmol·L^-1 for ABTS free radical scavenging ability, and total reduction capacity of compound 4 was better than vitamin C respectively. Compound 3 possessed better inhibitory effect on tyrosinase with IC₅₀ = 0.25 ± 0.06 mmol·L^-1.

ObjectiveTo investigate the role and mechanism of Go-Ichi-Ni-San complex subunit 1 （GINS1） in the progression of hepatocellular carcinoma （HCC） and the development of chemotherapy resistance. MethodsThe tumor database GEPIA2 was used to analyze the differential expression of GINS1 between HCC patients and healthy individuals， and pathological tissue samples were collected from 40 HCC patients who were admitted to The Affiliated Tumor Hospital of Xinjiang Medical University and the First Affiliated Hospital of Xinjiang Medical University from May 2017 to January 2021. Immunohistochemical staining was used to measure the difference in the expression of GINS1 between HCC tissue and corresponding adjacent tissue， and the correlation between the expression level of GINS1 and the clinical TNM stage of HCC was analyzed. Western blot was also used to measure the difference in the expression of GINS1 between HCC Huh7/Hep3B/Li-7/MHCC97H cell lines and normal human QSG7701 hepatocytes. The method of lentivirus transfection was used to establish the MHCC97H cell line with stable GINS1 knockdown and its negative control cell line. CCK-8 assay and colony formation assay were used to measure cell proliferative capacity； scratch assay was used to measure cell migration ability； Transwell assay was used to measure cell invasion ability； cells were treated with oxaliplatin to measure their sensitivity to chemotherapy drugs. Nude mice were used to establish a tumor-bearing model and observe the effect of GINS1 knockdown on the growth of HCC in vivo. Western Blot was used to measure the expression levels of the proteins associated with the Notch pathway and the JAK/STAT pathway. The cells were treated with the Notch receptor agonist Jagged-1 to analyze the association between GINS1 and the Notch/JAK/STAT pathway. The independent-samples t test was used for comparison of continuous data between two groups； a one-way analysis of variance was used for comparison between multiple groups， and the least significant difference t-test was used for further comparison between two groups. ResultsThe expression of GINS1 was upregulated in HCC patients， HCC tissue， and HCC cell lines （all P<0.05）， and the expression level of GINS1 was positively correlated with the clinical TNM stage of HCC （r=0.822， P=0.011）. Compared with the negative control cells， the GINS1-knockdown MHCC97H cells showed significant reductions in proliferation， migration， and invasion activities （all P<0.01） and a significantly enhanced sensitivity to oxaliplatin （P<0.01）. Compared with the nude mice in the control group， GINS1 knockdown caused significant inhibition of tumor weight and volume in vivo in nude mice （all P<0.001）. Compared with the negative control cells， the GINS1-knockdown MHCC97H cells showed significant reductions in the expression levels of Notch1， Notch3， p-JAK2， and p-STAT3 （all P<0.05）， while there were no significant differences in the overall expression levels of JAK2 and STAT3 （P>0.05）. After Jagged-1 treatment， the GINS1-knockdown MHCC97H cells showed significant increases in proliferation， migration， and invasion activities and a significant reduction in sensitivity to oxaliplatin， as well as significant increases in the levels of p-JAK2 and p-STAT3 （all P<0.05）. ConclusionGINS1 is upregulated in HCC and can promote HCC progression and chemotherapy resistance through the Notch/JAK2/STAT3 pathway.

Objective: To analyze the time varying characteristics of weight among Han primary and secondary school students in Xinjiang from 1985 to 2019, so as to provide a scientific basis for formulating nutrition policies for adolescents in ethnic minority areas. Methods: Weight data of Han primary and secondary school students aged 7-18 in Xinjiang from the National Student Physical Fitness and Health Survey from 1985 to 2019 were selected. Statistical analysis was conducted by using general linear model test, one way ANOVA and t-test. The weight development trends in 2025 and 2030 were predicted through time series analysis. Results: From 1985 to 2019, the weight of Han Chinese boys and girls from primary and secondary schools in Xinjiang showed a continuous upward trend (boys: B =0.25,girls: B =0.16, P <0.01). There were statistically significant differences in weight between boys and girls aged 7-18 in different years (boys: F =102.35-142.05, girls: F =98.03-140.59, P <0.01). Compared with 1985, the weight of urban boys and girls increased by 11.92 and 7.95 kg in 2019, as well as rural boys and girls by 11.36 and 5.61 kg, and the average weight gain of urban students was greater than that of rural students. From 1985 to 2019, the weight of urban boys and girls were higher than that of rural boys and girls (boys: t =30.12-37.55, girls: t =30.12-38.64, P <0.01). In 2005, the weight difference between urban and rural boys and girls was the largest, at 4.23 and 2.32 kg. The average weight of boys and girls in the age groups of 7-18 would continue to increase in 2025 and 2030; compared with 2019, the 7-year old age group for boys and the 17-year old age group for girls would have the largest growth in 2030 by 2.29 and 3.75 kg. Conclusions From 1985 to 2019, the weight of students aged 7-18 in Xinjiang showed an upward trend, and the weights of both boys and girls would gradually increase in 2025 and 2030. Attention should be paid to students physical health and adopt comprehensive measures to prevente overweight and obesity.
