Objective To explore the electroencephalography(EEG)characteristics of patients with knee osteoarthritis(KOA)which are different from those of healthy subjects during dynamic balance tests,and study the connection and influence between brain activity and KOA.Methods Fifteen patients with KOA and 17 healthy subjects performed the timed up and go test(TUGT)and five times sit-to-stand test(5STS).The EEG characteristics of the 4 frequency bands,namely δ(0.5-4 Hz),θ(4-8 Hz),α(8-14 Hz)and β(14-30 Hz)of 9 electrodes including CZ,C3,C4 in the central region,PZ,P3,P4 in the parietal lobe,and OZ,O1,O2 in the occipital lobe of the cerebral cortex of the subjects were recorded.Time and frequency domain analysis were conducted.Results During 5STS,the time-domain amplitudes of electrodes C4,P3,and P4 in the δ band,electrodes C4,P3,and P4 in the θ band,and electrodes P3 and P4 in the β band of KOA patients were significantly higher than those of healthy subjects(P<0.05);the power of EEG signals of electrodes P3,P4,and O2 in the β band was significantly higher than that of healthy subjects.During TUGT,except that the time-domain amplitude of electrode PZ in the θ band of KOA patients was significantly lower than that of healthy subjects(P<0.05),there was no significant difference in all electrodes in other frequency bands;the power of EEG signals of electrodes C3,CZ,C4,PZ,P4,O1,OZ,O2 in the δ band and electrodes CZ,P3,PZ,and OZ in the α band and electrodes CZ,P4,OZ,and O2 in the β band was significantly lower than that of healthy subjects(P<0.05).Conclusions Compared with healthy subjects,the activity in the parietal lobe area of the brain of KOA patients during 5STS was stronger,while the brain activity in the central region,parietal lobe,and occipital lobe areas of KOA patients during TUGT was weaker than that of healthy subjects.This study may provide some references for clinicians in the prevention and treatment of KOA.

OBJECTIVE To evaluate the efficacy,safety and economics of the centrally procured generic versus original esomeprazole in the treatment of acute non-variceal upper gastrointestinal bleeding(ANVUGIB).METHODS A retrospective collection of real-world clinical data was conducted for ANVUGIB patients who received treatment at Shenzhen People's Hospital and University of Hong Kong-Shenzhen Hospital from January 2018 to March 2024.Patients were divided into imported original drug group(original drug group,221 cases)and centrally procured generic drug group(generic drug group,75 cases)according to the types of drug used.Propensity score matching(PSM)was performed at a ratio of 3∶1 to compare the clinical efficacy,safety and economics between the two groups.RESULTS Totally 241 patients were included after PSM,with 170 in the original drug group and 71 in the generic drug group.There were no significant differences between the two groups in terms of rebleeding rate,rate of second endoscopic intervention,blood transfusion rate,length of hospital stay,mortality due to gastrointestinal bleeding,30-day readmission due to rebleeding,and overall survival rate(P＞0.05).The incidence of adverse events among all patients in both groups also showed no statistically significant difference(P＞0.05);furthermore,the adverse events reported by the respective hospitals to the National Center for ADR Monitoring were comparable between the two groups.After PSM,the median total drug cost and high-dose esomeprazole cost in the generic drug group were significantly lower than those in the original drug group,while the median nursing fee and bed fee were significantly higher than those in the original drug group(P＜0.05).There was no statistically significant difference between the two groups in terms of median total hospitalization expenses,total treatment costs,laboratory fees,examination fees,material costs,or consultation fees(P＞0.05).CONCLUSIONS The clinical efficacy and safety of centrally procured generic esomeprazole in the treatment of ANVUGIB are comparable to those of the original drug,and it is more economical.

OBJECTIVE: To preliminarily investigate the effects and mechanism of action of Yishen Yangsui Formula (, YSYSF)on the recovery of neurological function in rats with degenerative cervical myelopathy. METHODS: Fifty adult SD female rats were randomly divided into control group, sham group, model group, YSYSF group and positive drug group by using randomized numerical table method. In the model group, YSYSF group and positive drug group, polyvinyl alcohol acrylamide interpenetrating network hydrogel(water-absorbent swelling material) was used to construct a rat spinal cord chronic compression model. The sham group was implanted with the water-absorbent swelling material and then removed without causing spinal cord compression. The control group, the sham group and the model group were given equal amounts of saline by gavage, the group of YSYSF was given Chinese herbal medicine soup by gavage 9.1 g·kg^-1 once a day, and the positive drug group was given tetrahexylsalicylglucoside sodium monosialate ganglioside by intraperitoneal injection 4.2 mg·kg^-1 once a day. The motor function of the rats was assessed by the BBB method after 1, 3, 7, and 14 d of drug administration. The spinal cord tissues were taken from rats executed 14 d after drug administration, and the morphological changes of the spinal cord compression site were observed by HE staining, and the expression levels of Caspase-1, GSDMD, NLRP3, PYCARD, IL-1β, and IL-18 were detected in the area of spinal cord injury by Western blot method. RESULTS: The BBB scores of the control group and the sham group were normal at all time points after modeling, which were higher than the BBB scores of the model group, the YSYSF, and the positive drug group (P<0.05). From the 3rd day after gavage, at all time points, the BBB scores of rats in the YSYSF group and the positive drug group were higher than those of rats in the model group (P<0.05). The staining pattern of HE spinal cord tissue was normal in the control group and the sham group, and the HE spinal cord in the model group was severely damaged with a large number of neuron deaths, whereas the damage to the spinal cord and neuron cells was reduced in the YSYSF group and the positive drug group. The expression levels of caspase-1, GSDMD, NLRP3, PYCARD, IL-1β and IL-18 in the spinal cord of the model group were significantly higher than those of the sham group (P<0.0001), and the expression levels of caspase-1, GSDMD, NLRP3, PYCARD, IL-1β, and IL-18 in the YSYSF group and the drug group were significantly lower than those in the model group (P<0.05). CONCLUSION YSYSF can improve the motor function of rats with degenerative cervical spinal cord disease, alleviate the pathological changes, and promote the recovery of spinal cord neurological function. The specific mechanism may be related to the inhibition of the activation of inflammatory vesicles NLRP3 and PYCARD, the reduction of the release of inflammatory factors IL-1β and IL-18, the reduction of the expression of caspase-1 and GSDMD, the reduction of cellular death, and the inhibition of inflammatory response.

OBJECTIVE:To systematically assess the effect of blood flow restriction combined with endurance training on aerobic capacity,lower limb muscle strength,and sports performance of athletes using Meta-analysis. METHODS:3210 studies were searched in CNKI,VIP,WanFang,PubMed,Embase,Web of Science,ScienceDirect,and Cochrane databases before March 2023.After screening,12 studies and 14 research reports were included.The traditional Meta-analysis and network Meta-analysis were performed by Review Manager 5.4 and Stata 14. RESULTS:Endurance training with blood flow restriction had a medium effect size on maximal oxygen uptake(standardized mean difference(SMD)=0.59,95%confidence interval(CI):0.28-0.90,P＜0.05)and no heterogeneity.The effect of continuous pressure was better than the other pressure types(P＜0.05).Compared with sports events by anaerobic energy supply,sports events by aerobic energy supply showed better effects(P＜0.05),which was set as follows:4-8 weeks of aerobic training,20-30 minutes once,3 or more sessions per week,for a total of 12 or more sessions.Secondly,endurance training with blood flow restriction showed a large effect on the lower limb muscle strength(SMD=0.99,95%CI:0.61-1.37,P＜0.05)and no heterogeneity.A subgroup analysis showed muscle endurance was the best improved(SMD=1.11;95%CI:0.37-1.85),followed by knee extension strength(SMD=1.02,95%CI:0.37-1.67)and knee flexion strength(SMD=0.87,95%CI:0.24-1.51).Finally,endurance training with blood flow restriction showed a medium effect on sports performance(SMD=0.59,95%CI:0.13-1.06,P＜0.05),and the subgroup analysis showed a medium effect on running performance(SMD=0.55,95%CI:0.05-1.06,P＜0.05)and no heterogeneity.There was only one item of soccer specific performance that was not analyzed. CONCLUSION:Endurance training combined with blood flow restriction can improve the aerobic capacity,lower limb muscle strength,and sports performance of the athletes.And there is a large effect on lower limb muscle strength and a medium effect on aerobic capacity and sports performance.A training schedule of progressive mixed-intensity aerobic endurance training under continuous pressure for no less than 4 weeks,3 sessions per week,20-30 minutes per session,for 12 or more sessions in total is easy to obtain better training results.

Objective To explore the value of baseline plasma soluble type 2 myeloid cell trigger receptors(sTREM2)in evaluation for early hematoma enlargement in elderly patients with spontan-eous cerebral hemorrhage(SCH).Methods Clinical data of 240 patients with acute SCH admitted to our hospital from January 2020 to August 2022 were collected and analyzed retrospectively.According to the expansion of the hematoma volume,they were divided into non-expansion group(172 cases)and expanded group(68 cases).Baseline head CT scanning was performed in all patients within 24 h of onset,clinical and imaging data were analyzed,and the volume of cerebral hematoma was calculated.Blood samples were collected immediately after admission and sTREM2 and galectin-3 levels were measured.Results Compared with the non-expansion group,the ex-panded group had larger cerebral hematoma volume,and increased levels of sTREM2,galectin-3,hs-CRP and TNF-a at admission(P＜0.01).Pearson correlation analysis showed that the expres-sion levels of sTREM2 and galectin-3 were positively correlated with cerebral hematoma at ad-mission(r=0.784,P=0.012;r=0.815,P=0.004).ROC curve analysis indicated that the sensi-tivity of combined serum sTREM2 and galectin-3 levels was significantly higher than that of sin-gle detection(85.59％vs 73.73％and 64.41％,P＜0.05),and the AUC value was 0.896(95％CI:0.741-0.932).Conclusion The baseline plasma level of sTREM2 is significantly increased in eld-erly SCH patients after early hematoma expansion.So,sTREM2 can be used as a risk marker for early expansion of hematoma,and its combined detection with galectin-3 shows higher diagnostic value.

Objective:To investigate the value of dual-detector spectral CTA in distinguishing infarct core from penumbra in patients with acute ischemic stroke(AIS), and to further explore the risk factors associated with infarct core and their predictive value.Methods:The imaging and clinical data of 163 patients with AIS who met the inclusion criteria admitted to the Second Affiliated Hospital of Soochow University from March 2022 to May 2023 were retrospectively analyzed. Patients from March 2022 to December 2022 were used as the training group, and patients from January 2023 to May 2023 were used as the validation group for internal validation. The head and neck spectral CTA and brain CT perfusion imaging with dual-layer detector spectral CT were all carried out on all patients. Using CTP as reference, the patients were divided into infarct core group and non-infarct core group according to whether an infarct core occurred in the hypoperfusion regions of brain tissue. Multivariate logistic regression analysis was used to screen predictors related to the infarct core. The receiver operating characteristic (ROC) curve was used to evaluate the predictive efficacy.Results:A total of 163 patients were included in the study, including 112 in the training group and 51 in the validation group. There were significant differences in iodine density, effective atomic number, hypertension, triglyceride and neutrophils between the two groups ( P< 0.05). The cutoff values for iodine density values and effective atomic number values were 0.215 mg/mL and 7.405, respectively. Multivariate logistic regression analysis showed that iodine density and hypertension were independent risk factors for infarct core in AIS, and triglyceride was an independent protective factor. The area under the ROC curve (AUC) of iodine density value was the largest (0.859), with a sensitivity of 70.27%, and a specificity of 90.67%, which had a good predictive value. The ROC curve analysis results for the validation group were consistent with the training group. Conclusions:Spectral CT parameters iodine density values and effective atomic number values have the potential to distinguish the infarct core area from the penumbra area in patients with AIS. Iodine density and hypertension were independent risk factors of infarct core in AIS, triglyceride was an independent protective factor, and iodine density values obtained by dual-layer spectral detector CT had a high predictive value.

Objective CT scans combined with Mimics software were used to measure femoral offset(FO),rotation center height(RCH)and lower leg length discrepancy(LLD)following total hip arthroplasty(THA),and the relationship between FO,RCH and LLD after THA is discussed.Methods Retrospective analysis was performed on 40 patients with unilateral THA who met standard cases from October 2020 to June 2022.There were 21 males and 19 females,18 patients on the left side and 22 patients on the right side,aged range from 30 to 81 years old,with an average age of(58.90±14.13)years old,BMI ranged from 17.3 to 31.5 kg·m-2withan average of(25.3±3.4)kg·m-2.There were 30 cases of femoral head necrosis(Ficattype Ⅳ),2 cases of hip osteoarthritis(Tonnis type Ⅲ),2 cases of developmental hip dislocation combined with end-stage osteoarthritis(Crowe type Ⅲ),and 6 cases of femoral neck fracture(Garden type Ⅳ).Three-dimensional CT reconstruction of pelvis was taken preoperative and postoperative,and three-dimensional reconstruction model was established after processing by Mimics software.FO,RCH and LLD were measured on the model.The criteria for FO reconstruction were as follows:postoperative bi-lateral FO difference less than 5 mm;the standard for equal length of both lower limbs was as follows:postoperative LLD differ-ence less than 5 mm.Results Bilateral FO difference was positively correlated with LLD(r=0.744,P＜0.00l).Chi-square test was performed between the FO reconstructed group and the non-reconstructed eccentricity group:The results showed that the i-sometric ratio of lower limbs in the FO reconstructed group was significantly higher than that in the FO reconstructed group(x2=6.320,P=0.012).The bilateral RCH difference was significantly negatively correlated with LLD(r=-0.877,P＜0.001).There is a linear relationship between bilateral FO difference and bilateral RCH difference and postoperative LLD,and the lin-ear regression equation is satisfied:postoperative LLD=0.038x-0.099y+0.257(x:postoperative bilateral FO difference,y:post-operative bilateral RCH difference;Unit:cm),F=77.993,R2=0.808,P=0.009.Conclusion After THA,LLD increased with the increase of FO and decreased with the increase of RCH.The effect of lower limb isometric length can be obtained more easily by reconstruction of FO.There is a linear relationship between the bilateral FO difference and the bilateral RCH difference after THA and LLD,and the regression equation can provide a theoretical reference forjudging LLD.
