Objective: To analyze the intervention effects of moderate to vigorous classroom physical exercise on psychological sub health among Uyghur junior high school students, providing reference for mental health promotion and intervention in the ethnic group. Methods: From April to July 2022, 647 eighth grade Uighur junior high school students from two middle schools in the Kashgar Prefecture, Xinjiang, were selected using a random cluster digital sampling method. They were randomly assigned to a control group ( n =326) and an intervention group ( n =321). While adhering to the regular curriculum, the intervention group additionally received 12 week, 36 session (every Monday, Wednesday, and Friday afternoon) moderate to vigorous classroom physical exercise intervention (45 minutes per session, including warm up, main exercises, and cool down activities). Self administered psychological sub health was completed through Brief Instrument on Psychological Health of Youths before and after intervention, and the data were analyzed using covariance analysis. Results: Before intervention, there were no statistically significant differences between the control and intervention groups in the total scores for psychological sub health or in the scores for the three dimensions including emotional problems, conduct problems, and social adaptation difficulties ( t =0.76, 0.40, 0.01, 0.94 , all P >0.05). After intervention, the scores of the intervention group s junior high school students on the emotional problems, conduct problems, and social adaptation difficulties dimensions decreased by 0.50, 0.28, and 0.18, respectively, compared with the control group, and all differences were statistically significant ( t =3.35, 3.36, 2.07, all P <0.05). The main effect of the psychological sub health category was statistically significant ( F =60.66, P <0.01, partial η 2=0.09). Compared with the control group, the psychological sub health scores of junior high school students in the intervention group decreased by 0.96 ( t =3.42, P < 0.05 ). Conclusion The 12 week moderate to vigorous classroom physical exercise intervention has a positive effect on the psychological sub health of Uyghur junior high school students.

Objective To explore the imaging data and pathological factors affecting the postoperative recurrence of solitary fibrous tumor(SFT)of the central nervous system.Methods A retrospective analysis was conducted on the data of 40 patients with SFT confirmed by pathology.All patients were divided into recurrence group(n=12)and non-recurrence group(n=28)based on the follow-up results.Univariate analysis and Cox proportional hazards model were used to screen the risk factors of recurrence,and the Kaplan-Meier method was used to compare the recurrence-free survival(RFS)among different groups.Results Univariate analysis showed that the Ki-67 index in the recurrence group was significantly higher than that in the non-recurrence group(median 38.5%vs 10.0%,P<0.001),and the proportion of WHO grade 3 was higher than that in the non-recurrence group(66.67%vs 7.14%,P<0.001).MRI features were significantly associated with recurrence,including the maximum diameter of the tumor[(6.63±1.10)cm vs(4.16±1.64)cm,P<0.001],peritumoral edema(91.67%vs 28.57%,P<0.001),and midline structure shift(83.33%vs 17.86%,P<0.001).Multivariate analysis suggested that the risk of recurrence increased by 122%for each 1 cm increase in the maximum diameter of the tumor[hazard ratio(HR)=2.22,95%confidence interval(CI)1.33-3.72],and by 27%for each 1%increase in the Ki-67 index(HR=1.27,95%CI 1.02-1.61),respectively.Conclusion MRI features such as maximum diameter of the tumor,significant peritumoral edema,and midline structure shift should be alert to high recurrence risk,and with pathological grading and Ki-67 index,it can provide significant basis for prognosis evaluation.

The incidence of osteoporotic thoracolumbar vertebral fracture (OTLVF) in the elderly is gradually increasing. The kyphotic deformity caused by various factors has become an important characteristic of OTLVF and has received increasing attention. Its clinical manifestations include pain, delayed nerve damage, sagittal imbalance, etc. Currently, the definition and diagnosis of OTLVF with kyphotic deformity in the elderly are still unclear. Although there are many treatment options, they are controversial. Existing guidelines or consensuses pay little attention to this type of fracture with kyphotic deformity. To this end, the Lumbar Education Working Group of the Spine Branch of the Chinese Medicine Education Association and Editorial Committee of Chinese Journal of Trauma organized the experts in the relevant fields to jointly develop Clinical guidelines for the diagnosis and treatment of osteoporotic thoracolumbar vertebral fractures with kyphotic deformity in the elderly ( version 2024), based on evidence-based medical advancements and the principles of scientificity, practicality, and advanced nature, which provided 18 recommendations to standardize the clinical diagnosis and treatment.

Objective:To explore the correlations of neurological function recovery and intraoperative bone window parameters with intracranial pressure (ICP) changes at perioperative period in patients with large hemispheric infarction (LHI) after standard large bone flap decompression.Methods:Forty LHI patients accepted standard large bone flap decompression in Department of Neurosurgery, People's Hospital of Zhengzhou University from December 2020 to December 2023 were enrolled. ICP was measured before decompression, at the time of bone flap removal, during dural opening, and 24 h after decompression. Correlations of National Institutes of Health Stroke Scale (NIHSS), Extended Glasgow Outcome Scale (GOSE) and Glasgow Coma Scale (GCS) score changes, length and area of the bone window, bone window area/cranial bone area, infarct brain tissue volume/brain tissue volume with ICP changes were analyzed by Pearson's correlation. Length and area of bone window in patients with good neurological function recovery (NIHSS score decreased by≥5, GOSE score increased by≥3, or GCS score increased by≥3 before and after decompression) were calculated.Results:ICP at the time of bone flap removal, during dural opening, and 24 h after decompression was significantly lower than that before decompression ( P<0.05); ICP at the time of bone flap removal was higher than that at 24 h after decompression and during dural opening. Reduction between ICP before decompression and that during dural opening was more obvious than ICP reduction before and 24 h after decompression and ICP reduction before decompression and at the time of bone flap removal, with significant differences ( P<0.05). Postoperative NIHSS scores were significantly lower than preoperative ones ( P<0.05), and both postoperative GOSE and GCS scores were significantly higher than preoperative ones ( P<0.05). Decrease of NIHSS score, increase of GOSE and GCS scores before and after decompression were positively correlated with ICP reduction before and 24 h after decompression ( r=0.386, P=0.018; r=0.411, P=0.033; r=0.319, P=0.037); length and area of the bone window were positively correlated with ICP reduction before and 24 h after decompression ( r=0.461, P=0.028; r=0.536, P=0.034); bone window area/cranial bone area was positively correlated with ICP reduction before and 24 h after decompression ( r=0.438, P=0.027), while infarct brain tissue volume/brain tissue volume was negatively correlated with ICP reduction before and 24 h after decompression ( r=-0.371, P=0.031). Of the 40 patients, 25 had good neurological function recovery after decompression, with length of the bone window ranged 12.3-16.7 cm and area of the bone window ranged 54.5-91.9 cm 2. Conclusion:Standard large bone flap decompression can reduce ICP and improve prognosis in LHI patients; intraoperative bone window parameters are obviously correlated with ICP reduction before and 24 h after decompression; length of the bone window ranged 12.3-16.7 cm and area of the bone window ranged 54.5-91.9 cm 2 are suggested for decompression.

Objective:To explore the factors associated with severe bleeding after percutaneous nephrolithotomy (PCNL) in male patients and evaluate the efficacy of interventional embolization.Methods:A retrospective case series study was conducted at Nankai Hospital of Tianjin, China, from January 2018 to October 2021. The clinical data of 230 male patients with upper urinary tract stones were analyzed. The observation indicators included age, hypertension, diabetes, renal function abnormalities, history of preoperative anticoagulant use, stone size, stone type, number of puncture channels, operation time and degree of hydronephrosis. To describe the clinical characteristics of bleeding after percutaneous nephrolithotomy in men, and analyze the factors associated with severe bleeding after PCNL. Single factor analysis was performed using the Chi-square ( χ2) test, and multivariate analysis was performed using logistic regression analysis. Results:Univariate analysis showed that diabetes mellitus ( χ2=4.90, P=0.027), abnormal renal function ( χ2=18.32, P<0.001), history of preoperative oral anticoagulants ( χ2=5.10, P=0.024), abnormal bleeding and coagulation function ( χ2=8.22, P=0.004) and the number of puncture channels ( χ2=22.08, P<0.001) were the related factors affecting bleeding after PCNL. Multivariate logistic regression analysis showed that diabetes mellitus ( P=0.032), abnormal renal function ( P<0.001), and the number of puncture channels ( P<0.001) were the independent risk factors of bleeding after PCNL. Of the 28 patients with bleeding after PCNL, 25 were treated with interventional embolization, with a technical success rate of 100.0% and a clinical success rate of 89.3%. Conclusions:For patients with renal calculi and comorbid diabetes, renal function abnormalities, and multiple punctures, relevant preventive measures should be actively administered before PCNL to reduce the risk of postoperative bleeding. For patients with severe bleeding of the kidney after PCNL, TAE is a safe and effective minimally invasive treatment method.

OBJECTIVE To explore the role and underlying mechanism of tournefolic acid B （TAB） on the improvement of glucose metabolism and renal function in diabetic nephropathy （DN） model mice. METHODS DN model mice were established by high-fat diet combined with streptozotocin， and then randomly divided into model group， positive control group （vitamin E， 20 mg/kg）， TAB low-dose， medium-dose and high-dose groups （1， 2， 4 mg/kg）， with 12 mice in each group； normal control group was given regular diet. Each group was given relevant medicine or normal saline intragastrically， once a day， for 4 consecutive weeks. The glucose metabolic function was estimated by fasting blood glucose， glucose tolerance test， insulin tolerance test and serum insulin concentration. The renal coefficients and biochemical indicators related to renal function [serum uric acid， blood urea nitrogen， creatinine levels， and ratio of urine microalbumin to creatinine] were detected in mice； the contents of biochemical indicators related to oxidative stress [superoxide dismutase （SOD）， glutathione peroxidase （GSH-Px）， malondialdehyde （MDA）， 8-hydroxydeoxyguanosine （8-OHdG）] were determined in renal tissue of mice； the pathological morphology of renal tissue was observed； the expressions of extracellular matrix （ECM） deposition related factors [transforming growth factor β1 （TGF- β1）， fibronectin （Fn）， type Ⅳ collagen （Col Ⅳ）] and protein kinase B （Akt）/nuclear factor erythroid 2-related factor 2 （Nrf2）/heme oxygenase-1 （HO-1） pathway related proteins were determined in renal tissue of mice. RESULTS Compared with normal control group， fasting blood glucose， area under glucose tolerance curve， area under insulin tolerance curve， serum insulin content， the levels of uric acid， urea nitrogen and creatinine @qq.com and ratio of urinary microalbumin to creatinine in serum， the contents of MDA and 8-OHdG and the protein expressions of TGF-β1， Fn and Col Ⅳ were increased significantly in model group （P＜0.05）， while the contents of SOD， GSH-Px and the protein expressions of p-Akt， Nrf2， HO-1 in renal tissue were decreased significantly （P＜0.05）； the significant thickening of the basement membrane， accumulation of mesangial matrix， glomerulosclerosis and interstitial fibrosis of the renal tubules were all found. Compared with model group， above indexes of mice were all reversed significantly in TAB groups （P＜0.05）， and pathological changes were alleviated in a dose-dependent manner. CONCLUSIONS TAB can improve blood glucose metabolism and kidney function and alleviate renal tubulointerstitial fibrosis in DN model mice， the mechanism of which may be associated with activating the Akt/Nrf2/HO-1 signaling pathway and suppressing ECM deposition.

Objective:In general, patients with seropositive rheumatoid arthritis (RA) are considered to show an aggressive disease course. However, the relationship between the two subgroups in disease severity is controversial. Our study is aimed to compare the clinical characteristics and prognosis of double-seropositive and seronegative RA in China through a real-world large scale study.Methods:RA patients who met the 1987 American College of Rheumatology (ACR) classification criteria or the 2010 ACR/European Anti-Rheumatism Alliance RA classification criteria, and who attended the 10 hospitals across the country from September 2015 to January 2020, were enrolled. According to the serological status, patients were divided into 4 subgroups [rheumatoid factor (RF)(-) anti-cyclic citrullinated peptide (CCP) antibody (-), RF(+), RF(+) anti-CCP antibody(+), anti-CCP antibody(+)] and compared the disease characteristics and treatment response. One-way analysis of variance was used for measurement data that conformed to normal distribution, Kruskal-Wallis H test was used for measurement data that did not conform to normal distribution; paired t test was used for comparison before and after treatment within the group if the data was normally distributed else paired rank sum test was used; χ2 test was used for count data. Results:① A total of 2 461 patients were included, including 1 813 RF(+) anti-CCP antibody(+) patients (73.67%), 129 RF(+) patients (5.24%), 245 RF(-) anti-CCP antibody(-) patients (9.96%), 74 anti-CCP antibody(+) patients (11.13%). ② Regardless of the CCP status, RF(+) patients had an early age of onset [RF(-) anti-CCP antibody(-) (51±14) years old, anti-CCP antibody(+) (50±15) years old, RF(+) anti-CCP antibody(+) (48±14) years old, RF(+)(48±13) years old, F=3.003, P=0.029], longer disease duration [RF(-) anti-CCP antibody(-) 50 (20, 126) months, anti-CCP antibody(+) 60(24, 150) months, RF(+) anti-CCP antibody(+) 89(35, 179) months, RF(+) 83(25, 160) months, H=22.001, P<0.01], more joint swelling counts (SJC) [RF(-) anti-CCP antibody(-) 2(0, 6), Anti-CCP antibody(+) 2(0, 5), RF(+) anti-CCP antibody(+) 2(0, 7), RF(+) 2(0, 6), H=8.939, P=0.03] and tender joint counts (TJC) [RF(-) anti-CCP antibody(-) 3(0, 8), anti-CCP antibody(+) 2(0, 6), RF(+) anti-CCP antibody(+) 3(1, 9), RF(+) 2(0, 8), H=11.341, P=0.01] and the morning stiff time was longer [RF(-) anti-CCP antibody(-) 30(0, 60) min, anti-CCP antibody(+) 20(0, 60) min, RF(+) anti-CCP antibody(+) 30(10, 60) min, RF(+) 30(10, 60) min, H=13.32, P<0.01]; ESR [RF(-) anti-CCP antibody(-) 17(9, 38) mm/1 h, anti-CCP antibody(+) 20(10, 35) mm/1 h, RF(+) anti-CCP antibody(+) 26(14, 45) mm/1 h, RF(+) 28(14, 50) mm/1 h, H=37.084, P<0.01] and CRP [RF(-) anti-CCP antibody(-) 2.3 (0.8, 15.9) mm/L, Anti-CCP antibody(+) 2.7(0.7, 12.1) mm/L, RF(+) anti-CCP antibody(+) 5.2(1.3, 17.2) mm/L, RF (+) 5.2(0.9, 16.2) mm/L, H=22.141, P<0.01] of the RF(+)patients were significantly higher than RF(-) patients, and RF(+) patients had higher disease severity(DAS28-ESR) [RF(-) anti-CCP antibody(-) (4.0±1.8), anti-CCP antibody(+) (3.8±1.6), RF(+) anti-CCP antibody(+) (4.3±1.8), RF(+) (4.1±1.7), F=7.269, P<0.01]. ③ The RF(+) anti-CCP antibody(+) patients were divided into 4 subgroups, and it was found that RF-H anti-CCP antibody-L patients had higher disease severity [RF-H anti-CCP antibody-H 4.3(2.9, 5.6), RF-L anti-CCP antibody-L 4.5(3.0, 5.7), RF-H anti-CCP antibody-L 4.9(3.1, 6.2), RF-L anti-CCP antibody-H 2.8(1.8, 3.9), H=20.374, P<0.01]. ④ After 3-month follow up, the clinical characteristics of the four groups were improved, but there was no significant difference in the improvement of the four groups, indicating that the RF and anti-CCP antibody status did not affect the remission within 3 months. Conclusion:Among RA patients, the disease activity of RA patients is closely related to RF and the RF(+) patients have more severe disease than RF(-) patients. Patients with higher RF titer also have more severe disease than that of patients with low RF titer. After 3 months of medication treatment, the antibody status does not affect the disease remission rate.

Objective To observe the clinical efficacy of Dachaihu decoction in treatment of stroke-associated pneumonia (SAP) in the elderly patients with excess-heat syndrome and acute ischemic stroke (AIS). Methods One hundred elderly patients with excess-heat syndrome and SAP admitted to the Department of Neurology of Tianjin Nankai Hospital from August 2015 to September 2016 were enrolled, and they were divided into a control group and an observation group according to the random number table, 50 cases in each group. Both groups were given conventional neurological treatment, while the observation group additionally received Dachaihu decoction (the ingredients of the decoction: bupleurum 15 g, scutellariae 10 g, pinellia 10 g, fructus aurantii immaturus 15 g, radix paeoniae alba 10 g, rhubarb 5 g, ginger 10 g, jujube 2), and according to the individual's symptoms and signs, the above ingredients can be added and/or subtracted, 1 dose per day, divided into two parts, 1 part taken in the morning and 1 part in the evening orally, 14 days as a therapeutic course. The body temperature recovery time, the duration of antibiotic treatment, the changes of Clinical Pulmonary Infection Score (CPIS) and National Institutes of Health Stroke Scale (NIHSS) score before and after treatment of the two groups were observed and the therapeutic effects in the two groups were evaluated. Results The body temperature recovery time (days: 6.56±2.70 vs. 8.08±3.23) and the duration of antibiotic treatment (days: 8.78±2.80 vs. 10.02±2.90) in the observation group were significantly shorter than those in the control group (both P ＜ 0.05); with the prolongation of treatment, after treatment, the CPIS and NIHSS score were decreased significantly in both groups, reaching the lowest levels on the 14th day, and the degrees of score descent in observation group were more significant than those of the control group (CPIS score: 0.68±0.59 vs. 1.12±0.96, NIHSS score: 6.38±2.31 vs. 7.44±2.74, both P ＜ 0.05); the total effective rate in the observation group was significantly higher than that in the control group [92% (46/50) vs. 76% (38/50), P ＜ 0.05]. Conclusion The therapeutic effect of Dachaihu decoction used for treatment of SAP in elderly patients with excess-heat syndrome is favorably effective and safe.
