Objective To investigate whether glaucocalyxin A can reduce inflammatory response in rats with trau-matic fracture.Methods The rats were randomly divided into control group,model group,low GLA(GLA-L),high GLA dose group(GLA-H)and GLA?H+YC?1(HIF?1α inhibitor)group.The level of TNF?α,IL?6,CTX?Ⅰ,CTX?Ⅱ,S?Ca,S?P,BGP and the activities of iNOS and ALP were detected by ELISA.The density and thickness of bone trabeculae were measured by computed tomography.Apoptosis of femur tissue was detected by TUNEL.The cartilage morphology was observed by saffranin O?fast green staining.Western blot was applied to de?tect the expression of HIF?1α,VEGF,CD31,BMP?2,and collagenⅠ proteins in femoral tissue.Results Compared with the control group,the cartilage morphology of rats in the model group was significantly damaged,the level of serum TNF?α,IL?6,CTX?Ⅰ,CTX?Ⅱ,iNOS activity and apoptosis rate of femur tissue were in?creased.Serum S?Ca,S?P,BGP levels,ALP activity,bone trabecular density and thickness,HIF?1α,VEGF,CD31,BMP?2,collagen Ⅰ protein expression levels in femur tissue were all decreased(P<0.05).The mor?phology of cartilage tissue in GLA?L and GLA?H groups was significantly improved,and the level of serum TNF?α,IL?6,CTX?Ⅰ,CTX?Ⅱ,iNOS activity and apoptosis rate of femur tissue were all significantly de?creased.Serum levels of S?Ca,S?P,BGP,ALP activity,bone trabecular density and thickness,HIF?1α,VEGF,CD31,BMP?2,collagen Ⅰ protein expression level in femur tissue were significantly increased(P<0.05).YC?1 was able to weaken the therapeutic effect of GLA on traumatic fracture rats(P<0.05).Conclusions GLA alleviates inflammation and cartilage damage in rats with traumatic fractures,promotes angio?genesis and improves femoral morphology,possibly by activating the HIF?1α/VEGF signaling pathway.

Objective To compare the effect between unilateral and bilateral upper limb training on motor function of severely hemi-plegic upper limbs in subacute stroke patients after priming robot-assisted training.Methods From September,2023 to December,2024,60 inpatients with hemiplegia after stroke were recruited from Guangdong Work Injury Rehabilitation Hospital,and randomly divided into control group(n=30)and experi-mental group(n=30).Both groups first received 30 minutes of upper limb robot-assisted training.Subsequently,the control group received movement-based unilateral upper limb training for 30 minutes,while the experimental group received activity-based bilateral upper limb training for 30 minutes,for three weeks.They were assessed with Fugl-Meyer Assessment-Upper Extremities(FMA-UE),Hong Kong version of the Functional Test for the Hemiplegic Upper Extremity(FTHUE-HK)and modified Barthel Index(MBI)before and after treatment.Results The scores of FMA-UE,FTHUE-HK and MBI improved in both groups after treatment(t>4.020,P<0.01),and all the scores were better in the experimental group than in the control group(t>2.456,P<0.05).Conclusion Activity-based bilateral upper limb training after priming robot-assisted training is more effective on motor function of severely hemiplegic upper limbs in stroke patients.

In recent years, adaptive laboratory evolution (ALE) has emerged as a powerful tool for basic research in microbiology (e.g., molecular mechanisms of microbial evolution) and efforts on evolutionary engineering of microbial strains (e.g., accelerated evolution of industrial strains by bringing beneficial mutations). The ongoing rapid development of next-generation sequencing platforms has provided novel insights into growth kinetics and metabolism of microbes, and thus led to great advances of this technique. In this review, we summarize recent advances in the applications of long-term and short-term ALE techniques mainly for microbial strain engineering, and different modes of ALE are also introduced. Furthermore, we discuss the current limitations of ALE and potential solutions. We believe that the information reviewed here will make a significant contribution to further advancement of ALE.

Objective:To analyze the association of clinical characteristics and laboratory indicators at initial maintenance hemodialysis(MHD)with long-term prognosis in advance-aged patients, and to find influencing factors for the prognosis in advance-aged MHD patients.Methods:This retrospective study was conducted at the Nephrology Department of Beijing Hospital between April 2007 and January 2018.A total of 61 patients receiving first-time hemodialysis at ≥ 80 years of age and undergone regular dialysis for 3 months or longer were enrolled.All patients were followed-up until death or the end of July 1, 2018.Patients were divided into the survivor and non-survivor groups, and differences in clinical characteristics and laboratory indicator values were compared between the two groups.Influencing factors for prognosis in advance-aged MHD patients were analyzed by using multivariate Cox regression.Results:For the 61 subjects, the median follow-up time was 25.8 months.During the follow-up, 32 patients died(52.5%). The main death causes were infectious diseases(40.6%, n=13)and cardiovascular and cerebrovascular diseases(37.5%, n=12). The 1-, 2-, 3-, 4-, and 5-year cumulative survival rates were 75.4%(46/61), 54.1%(33/61), 37.7%(23/61), 22.9%(14/61)and 16.4%(10/61), respectively.The median survival time was 25.8 months for all patients, 27.5 months for patients aged 80-84 years, and 14.9 months for patients aged 85 years and over.The non-survivor group had a higher male ratio(65.6% or 21/32 vs.37.9% or 11/29, χ2=4.678, P=0.031)and lower levels of hemoglobin(85.4±13.0 vs.95.0±17.6 g/L, t=2.867, P=0.019)and albumin(30.3±5.0 vs.34.6±4.8 g/L, t=3.039, P=0.001)than the survivor group.Kaplan-Meier curves indicated that the survival rate decreased with age, and subjects aged less than 85 years had a higher survival rate than subjects aged 85 years and older(the median survival time: 14.9 months vs.27.5 months, Log Rank P=0.006); patients who received continuous renal replacement therapy(CRRT)before dialysis had lower survival rates than patients who did not receive CRRT(the median survival time: 7.8 months vs.29.2 months, Log Rank P=0.002); patients with high serum levels of albumin(≥33 g/L)had higher survival rates than patients with low serum levels of albumin(<33 g/L)(the median survival time: 29.2 months vs.18.9 months, Log Rank P=0.003). Multivariate Cox regression analysis showed that age at initial dialysis( HR=1.136, 95% CI: 1.005-1.285, P=0.041), female( HR=0.409; 95% CI: 0.169-0.994, P=0.048), serum albumin level( HR=0.836, 95% CI: 0.772-0.906, P<0.001)and CRRT before dialysis( HR=6.161, 95% CI: 1.848-20.538, P=0.003)were independent predictors of all-cause mortality in advance-aged patients. Conclusions:Advance-aged patients undergoing hemodialysis have complicated clinical conditions and poor prognosis.Age, gender and serum albumin level at initial dialysis and CRRT before dialysis are independent predictors of prognosis in these patients.

Objective:To explore the changes in the diffusion tensor imaging (DTI) parameters of the pontocerebellar tract 3 months and one year after ischemic stroke and analyze the data′s potential for predicting long-term motor outcomes.Methods:Thirty patients with middle cerebral artery infarction were prospectively studied using DTI within 3 months and 1 year after the onset. A region of interest-based analysis was performed for the fractional anisotropy (FA) of the middle cerebellar peduncles (MCP) in the pontocerebellar fibers (PCF). Neurological functioning was evaluated using the National Institutes of Health Stroke Scale and the degree of paresis was assessed at the same time using paresis grading. At one year after the onset, balance function, functional prognosis and self-care ability were evaluated using the Brunel Balance Scale, the modified Rankine Scale and the Functional Independence Scale respectively.Results:The average FA on the healthy side 3 months and 1 year after onset was significantly less than on the affected side at each time point. The ratio of the FA of the affected side to that of the unaffected side (rFA) in the PCF correlated significantly with the average paresis scores of the lower and upper extremity and the total paresis score at each time point. Moreover, the rFA of the PCF was significantly correlated with the average functional independence score, the prognosis for the upper and lower extremities as well as motor functioning. The area ratio under the ROC curve of the PCF for predicting lower extremity motor outcome was 0.84, and the optimal threshold was 0.92 (sensitivity 71.4%, specificity 73.9%). The area ratio under the ROC curve was not a significant predictor of upper extremity motor outcome.Conclusion:The DTI parameter rFA of the PCF in patients with subacute middle cerebral artery infarction can help to predict the long-term recovery of motor ability. It can serve as an important reference index for predicting the long-term motor ability of the lower limbs.
