Objective: To investigate the effects of endurance running at different intensities on self-control of sedentary university students, and to reveal the immediate and sustained effects of exercise on cognitive control. Methods: Ninety students with sedentary behaviors from 7 universities in a university city in Shandong Province were selected by cluster stratified random sampling. 21, 23, 21 and 25 students in the high, medium and low intensity groups and the blank control group completed the 30min endurance running exercise, combined with the willingness of the subjects. The Stroop test was conducted immediately after exercise, 5, 15 and 30 min after exercise, and the correct rate and response time of the Stroop test were used as two indicators of self-control. Results: In the immediate post-exercise period, the correct response time for the control group ( 774.03 ±127.85)ms], the high-intensity group [(745.37±109.59)ms], the moderate-intensity group [(627.90±129.18)ms] and the low-intensity group [(689.90±129.79)ms] were statistically significant ( F =6.27, P <0.05). The correct rate for the control group [(94.40±2.02)%], the low-intensity group [(95.38±1.96)%], the high-intensity group [(92.43±2.32)%] and the moderate-intensity group [(96.39±1.08)%] were statistically significant ( F =14.87, P <0.05). High-intensity endurance running exercise was able to achieve the best performance at 30 min and beyond on the Stroop test response and correctness ( P <0.05), while moderate-intensity endurance running had a better effect on improving self-control than low-intensity endurance running at 30 min post-exercise. Conclusion High and moderate-intensity endurance running exercises can effectively improve self-control in sedentary university students. It is recommended that moderate or high intensity endurance running be performed as the body can tolerate it to improve self-control and cognitive ability.

[Objective]To investigate the chemical compositions,antioxidant and anti-inflammatory activities of Jiangshan Polygonatum sibiricum alcoholic extract(PSAE)in vitro.[Methods]The chemical compositions of PSAE were identified by ultra performance liquid chromatography-quadrupole time-of-flight mass spectrometry(UPLC-Q/TOF-MSE),its antioxidant activity was studied,and in vitro experiments were conducted to determine its effect on lipopolysaccharide(LPS)-induced THP-1 cells.Molecular docking was further used to validate the results.[Results]PSAE contained 17 chemical compositions,including 5 flavonoids,5 saponins,3 lignans,1 phenolic acid,1 steroid and 2 other compositions.In vitro experiments showed that PSAE possessed great antioxidant activity.Besides,PSAE could increase the viability of LPS-induced THP-1 cells,significantly decrease the levels of tumor necrosis factor-α(TNF-α)and interleukin-1β(IL-1β)in cell supernatants and the expression of NOD-like receptor thermal protein domain associated protein 3(NLRP3),apoptosis-associated speck-like protein containing CARD(ASC)and cysteinyl aspartate specific proteinase-1(Caspase-1).Molecular docking results showed that 16 of the 17 chemical compositions detected in PSAE had good docking activities with the core targets of NLRP3,ASC and Caspase-1.[Conclusion]PSAE has great antioxidant and anti-inflammatory activities,and the main active compositions may be flavonoids and saponins.

Objective:To investigate the early outcome of endoscopy-assisted percutaneous non-fusion fixation of unilateral C 1 lateral mass screw and C 2 pedicle screw in treatment of type II odontoid fracture in elderly patients. Methods:A retrospective case series study was conducted to analyze clinical data of 12 elderly patients with type II odontoid fracture admitted to Second Affiliated Hospital of Chongqing Medical University from July 2016 to September 2018. There were 5 males and 7 females, aged 66-89 years [(75.2±6.7)years]. American Society of Anesthesiologists (ASA) scores for all patients were greater than 2 points. Ten patients were classified to Grade E and the other two were classified to Grade D by American Spinal Injury Association (ASIA) scale scores. All patients underwent endoscopy-assisted percutaneous non-fusion fixation of unilateral C 1 lateral mass screw and C 2 pedicle screw. The operation time, intraoperative blood loss, hospital stays, intraoperative and postoperative complications were collected. The Neck Disability Index (NDI) scores and ASIA scale scores were compared preoperatively and 6 weeks postoperatively. The visual analogue scales (VAS) were recorded preoperatively, 6 weeks, 3, 6, 9 and 12 months postoperatively. Fracture healing was followed up postoperatively. Results:Operation time was 98-169 minutes [(123.2±17.7)minutes]. Intraoperative blood loss was 20-40 ml [(30.0±7.1)ml]. Hospital stays were 6-9 days [(7.3±0.7)days]. No neurovascular injury was observed intraoperatively and postoperatively. The NDI were 8%-30%[(19.3±6.3)%] 6 weeks postoperatively, significantly lower than 19%-45%[(33.1±9.9)%] preoperatively( P<0.05). All patients' ASIA scale scores reached grade E postoperatively. The VAS constantly decreased from 6-9 points [(7.8±0.9)points] preoperatively to 1-3 points [(1.8±0.6)points] 12 months postoperatively ( P<0.05). All the patients achieved bone healing after 4-11 months [(7.3±2.1)months]. Conclusion:For type II odontoid fracture in elderly patients, endoscopy-assisted percutaneous unilateral atlantoaxial screw non-fusion fixation can relieve pain and achieve rapid recovery of neck function and bone healing.

OBJECTIVE:This paper collects relevant literature on blood flow restriction training combined with resistance training,and analyzes the different effects of blood flow restriction training combined with resistance training on athletes'muscle-related indexes and specialized abilities in accordance with the paradigm of systematic evaluation and Meta-analysis,aiming to provide data support for athletes to utilize blood flow restriction training in their training practices. METHODS:Chinese and foreign databases(CNKI,WanFang,PubMed,Web of Science,SPORTDiscus)were searched to collect randomized controlled trials on the effects of blood flow restriction training combined with resistance training on limb circumference,muscle mass,muscle strength,and specialized ability of college athletes from January 1st,2000 to October 12th,2023.At least two researchers evaluated the quality of the included literature using the Cochrane Collaboration risk of bias assessment tools and criteria.Heterogeneity tests,data merging,subgroup analyses,forest plotting,and sensitivity analyses were performed using RevMan 5.4,and funnel plots with publication bias evaluation and sensitivity analyses were performed.The evaluation indexes were limb circumference,muscle thickness,muscle strength and specialized ability,and subgroup analyses were performed for different specialized athletic abilities. RESULTS:(1)A total of 18 randomized controlled trials with 403 subjects were included,and according to the Cochrane Collaboration's risk of bias assessment tool,the quality of literature in the included literature was grade A in 16 articles and grade B in 2 articles.(2)Comparing the effects of blood flow restriction training combined with resistance training and resistance training,there was no significant difference between the two groups in terms of limb circumference[standardized mean difference(SMD)=0.03,95%confidence interval:-0.16-0.21,P=0.78],and a significant difference between the two groups in terms of muscle thickness(SMD=0.14,95%CI:0.01-0.27,P=0.03)and muscle strength(SMD=0.37,95%CI:0.14-0.60,P=0.001).(3)Subgroup analyses of the indicators of specialized capacity indicated that there was high heterogeneity in the analyzed results of distance metrics(I2=73%)and time metrics(I2=55%),which was analyzed as a possible reason due to the differences in testing methods and assessment of metrics'significance in the studies;there was no heterogeneity(I2=0%)in the analyzed results of power metrics;blood flow restriction training combined with resistance training had a significant effect on distance metrics(P<0.01).(4)The results of the combined effect showed the effect of blood flow restriction training combined with resistance training vs.resistance training for specialized ability(P=0.41),suggesting that there is no significant effect of different training methods on specialized ability. CONCLUSION:Both blood flow restriction training combined with resistance training and resistance training can promote muscle thickness,muscle strength and specialized ability in college athletes.Meanwhile,blood flow restriction training combined with resistance training has a more significant effect on muscle thickness,muscle strength and some specialized abilities compared with resistance training.Therefore,blood flow restriction training can be scientifically and rationally integrated into specialized training,so as to achieve a better training effect by integrating the differentiated physiological stimuli to the muscles.However,due to the small number of included studies and other possible limitations,more high-quality,multi-sport type and sex randomized trials need to be included in the future to confirm this.

OBJECTIVES: To evaluate the value of thrombospond in Type I domain-containing 7A (THSD7A) and M-type phospholipase A2 receptor (PLA2R) in primary membranous nephropathy (PMN) and to explore the relationship between their antibody levels and prognosis. METHODS: Renal tissues in 128 patients with membranous nephropathy in the Second Xiangya Hospital of Central South University were collected from February 2015 to August 2017, including 108 patients with primary membranous nephropathy (PMN group) and 20 patients with secondary membranous nephropathy (SMN) (SMN group). Indirect immunofluorescence method was used to detect the expression of PLA2R antigen in kidney tissues,and the glomerular expression of THSD7A antigen was examined by immunohistochemistry and indirect immunofluorescence. The serum levels of anti-PLA2R antibodies and THSD7A antibodies were also detected by ELISA. According to the results of PMN examination,the patients were also divided into a PLA2R-related membranous nephropathy group and a THSD7A-related membranous nephropathy group. RESULTS: The positive rate of PLA2R in the renal tissues in the PMN group was higher than that in the SMN group (78% in the PMN group, 35% in the SMN group, <0.01),while the positive rate of anti-PLA2R antibody in the PMN group was also higher than that in the SMN group (50% in the PMN group, 25% in the SMN group, <0.05).The serum level of anti-PLA2R antibody was positively correlated with 24 h urine protein (=0.254, <0.05) and negatively correlated with serum albumin (=-0.236, <0.05). The expression of THSD7A was positive in glomeruli in 7 cases of the PMN group (6%) by immuno-histochemistry, and which was positive in 1case of the SMN group (5%).The serum levels of anti-THSD7A antibody in the PMN group were higher than those in the SMN group [(0.49±0.26) pg/mL in the PMN group,(0.34±0.27) pg/mL in the SMN group, <0.05]. There was no difference in the clinical characteristics between the PLA2R-related membranous nephropathy group and the THSD7A-related membranous nephropathy group. CONCLUSIONS PLA2R and THSD7A are the target antigen of PMN, and the associated autoantibodies are helpful for the differential diagnosis of PMN. The anti-PLA2R antibody levels can reflect the severity of the disease and evaluate the effect of treatment. The incidence of THSD7A membranous nephropathy is low, and monitoring the serum anti-THSD7A antibody levels can assess patients' condition and predict disease outcome.
