ObjectiveFunctional near-infrared spectroscopy (fNIRS), a novel non-invasive technique for monitoring cerebral activity, can be integrated with upper limb rehabilitation robots to facilitate the real-time assessment of neurological rehabilitation outcomes. The rehabilitation robot is designed with 3 training modes: passive, active, and resistance. Among these, the resistance mode has been demonstrated to yield superior rehabilitative outcomes for patients with a certain level of muscle strength. The control modes in the resistance mode can be categorized into dynamic and static control. However, the effects of different control modes in the resistance mode on the motor function of patients with upper limb hemiplegia in stroke remain unclear. Furthermore, the effects of force, an important parameter of different control modes, on the activation of brain regions have rarely been reported. This study investigates the effects of dynamic and static resistance modes under varying resistance levels on cerebral functional alterations during motor rehabilitation in post-stroke patients. MethodsA cohort of 20 stroke patients with upper limb dysfunction was enrolled in the study, completing preparatory adaptive training followed by 3 intensity-level tasks across 2 motor paradigms. The bilateral prefrontal cortices (PFC), bilateral primary motor cortices (M1), bilateral primary somatosensory cortices (S1), and bilateral premotor and supplementary motor cortices (PM) were examined in both the resting and motor training states. The lateralization index (LI), phase locking value (PLV), network metrics were employed to examine cortical activation patterns and topological properties of brain connectivity. ResultsThe data indicated that both dynamic and static modes resulted in significantly greater activation of the contralateral M1 area and the ipsilateral PM area when compared to the resting state. The static patterns demonstrated a more pronounced activation in the contralateral M1 in comparison to the dynamic patterns. The results of brain network analysis revealed significant differences between the dynamic and resting states in the contralateral PFC area and contralateral M1 area (F=4.709, P=0.038), as well as in the contralateral PM area and ipsilateral M1 area (F=4.218, P=0.049). Moreover, the findings indicated a positive correlation between the activation of the M1 region and the increase in force in the dynamic mode, which was reversed in the static mode. ConclusionBoth dynamic and static resistance training modes have been demonstrated to activate the corresponding brain functional regions. Dynamic resistance modes elicit greater oxygen changes and connectivity to the region of interest (ROI) than static resistance modes. Furthermore, the effects of increasing force differ between the two modes. In patients who have suffered a stroke, dynamic modes may have a more pronounced effect on the activation of exercise-related functional brain regions.

BACKGROUND:
The primary limitation to kidney transplantation is organ shortage. Recent progress in gene editing and immunosuppressive regimens has made xenotransplantation with porcine organs a possibility. However, evidence in pig-to-human xenotransplantation remains scarce, and antibody-mediated rejection (AMR) is a major obstacle to clinical applications of xenotransplantation.
METHODS:
We conducted a kidney xenotransplantation in a brain-dead human recipient using a porcine kidney with five gene edits (5GE) on March 25, 2024 at Xijing Hospital, China. Clinical-grade immunosuppressive regimens were employed, and the observation period lasted 22 days. We collected and analyzed the xenograft function, ultrasound findings, sequential protocol biopsies, and immune surveillance of the recipient during the observation.
RESULTS:
The combination of 5GE in the porcine kidney and clinical-grade immunosuppressive regimens prevented hyperacute rejection. The xenograft kidney underwent delayed graft function in the first week, but urine output increased later and the single xenograft kidney maintained electrolyte and pH homeostasis from postoperative day (POD) 12 to 19. We observed AMR at 24 h post-transplantation, due to the presence of pre-existing anti-porcine antibodies and cytotoxicity before transplantation; this AMR persisted throughout the observation period. Plasma exchange and intravenous immunoglobulin treatment mitigated the AMR. We observed activation of latent porcine cytomegalovirus toward the end of the study, which might have contributed to coagulation disorder in the recipient.
CONCLUSIONS
5GE and clinical-grade immunosuppressive regimens were sufficient to prevent hyperacute rejection during pig-to-human kidney xenotransplantation. Pre-existing anti-porcine antibodies predisposed the xenograft to AMR. Plasma exchange and intravenous immunoglobulin were safe and effective in the treatment of AMR after kidney xenotransplantation.

The study investigated the intrinsic changes in material basis of Angelicae Sinensis Radix during wine processing by headspace-gas chromatography-ion mobility spectrometry(HS-GC-IMS), headspace-solid phase microextraction-gas chromatography-mass spectrometry(HS-SPME-GC-MS), and ultra-high performance liquid chromatography-quadrupole-orbitrap mass spectrometry(UPLC-Q-Orbitrap-MS) combined with chemometrics. HS-GC-IMS fingerprints of Angelicae Sinensis Radix before and after wine processing were established to analyze the variation trends of volatile components and characterize volatile small-molecule substances before and after processing. Principal component analysis(PCA) and orthogonal partial least squares-discriminant analysis(OPLS-DA) were employed for differentiation and difference analysis. A total of 89 volatile components in Angelicae Sinensis Radix were identified by HS-GC-IMS, including 14 unsaturated hydrocarbons, 16 aldehydes, 13 ketones, 9 alcohols, 16 esters, 6 organic acids, and 15 other compounds. HS-SPME-GC-MS detected 118 volatile components, comprising 42 unsaturated hydrocarbons, 11 aromatic compounds, 30 alcohols, 8 alkanes, 6 organic acids, 4 ketones, 7 aldehydes, 5 esters, and 5 other volatile compounds. UPLC-Q-Orbitrap-MS identified 76 non-volatile compounds. PCA revealed distinct clusters of raw and wine-processed Angelicae Sinensis Radix samples across the three detection methods. Both PCA and OPLS-DA effectively discriminated between the two groups, and 145 compounds(VIP>1) were identified as critical markers for evaluating processing quality, including 4-methyl-3-penten-2-one, ethyl 2-methylpentanoate, and 2,4-dimethyl-1,3-dioxolane detected by HS-GC-IMS, angelic acid, β-pinene, and germacrene B detected by HS-SPME-GC-MS, and L-tryptophan, licoricone, and angenomalin detected by UPLC-Q-Orbitrap-MS. In conclusion, the integration of the three detection methods with chemometrics elucidates the differences in the chemical material basis between raw and wine-processed Angelicae Sinensis Radix, providing a scientific foundation for understanding the processing mechanisms and clinical applications of wine-processed Angelicae Sinensis Radix.

With the vigorous promotion of organ donation after citizen death in China, increased utilization of marginal livers, and continuous expansion of hepatocellular carcinoma indications for liver transplantation, innovations in techniques such as auxiliary liver transplantation, pediatric liver transplantation, laparoscopic liver transplantation, magnetic liver transplantation,and non-ischemic liver transplantation have significantly improved the number of liver transplantation surgery performed, patient survival rates, and graft survival rates in China, while complication rates have gradually decreased. As such,liver transplantation in China has reached leading or advanced levels internationally. In the new development context,Chinese liver transplantation faces new opportunities and challenges for development. Evolutions in basic diseases of transplant recipients and tumor classifications of will further broaden the population eligible for transplantation and introduce new demands for liver transplantation procedures. Emerging technologies including artificial organs, xenotransplantation,and artificial intelligence are bringing prospects for advancing liver transplantation. Looking ahead, the progression of liver transplantation will go beyond prioritizing patient survival rates and graft survival rates alone, instead emphasizing improved quality of life for transplant recipients post-surgery to an even greater extent.

Objective:To investigate the effect of CD8+CD28-T cells on acute graft-versus-host disease(aGVHD)after haploidentical hematopoietic stem cell transplantation(haplo-HSCT).Methods:The relationship between absolute count of CD8+CD28-T cells and aGVHD in 60 patients with malignant hematological diseases was retrospectively analyzed after haplo-HSCT,and the differences in the incidence rate of chronic graft-versus host disease(cGVHD),infection and prognosis between different CD8+CD28-T absolute cells count groups were compared.Results:aGVHD occurred in 40 of 60 patients after haplo-HSCT,with an incidence rate of 66.67%.The median occurrence time of aGVHD was 32.5(20-100)days.At 30 days after the transplantation,the absolute count of CD8+CD28-T cells of aGVHD group was significantly lower than that of non-aGVHD group(P=0.03).Thus the absolute count of CD8+CD28-T cells at 30 days after transplantation can be used to predict the occurrence of aGVHD to some extent.At 30 days after transplantation,the incidence rate of aGVHD in the low cell count group(CD8+CD28-T cells absolute count<0.06/μl)was significantly higher than that in the high cell count group(CD8+CD28-T cells absolute count ≥0.06/μl,P=0.011).Multivariate Cox regression analysis further confirmed that the absolute count of CD8+CD28-T cells at 30 days after transplantation was an independent risk factor for aGVHD,and the risk of aGVHD in the low cell count group was 2.222 times higher than that in the high cell count group(P=0.015).The incidence of cGVHD,fungal infection,EBV infection and CMV infection were not significantly different between the two groups with different CD8+CD28-T cells absolute count.The overall survival,non-recurrent mortality and relapse rates were not significantly different between different CD8+CD28-T cells absolute count groups.Conclusion:Patients with delayed CD8+CD28-T cells reconstitution after haplo-HSCT are more likely to develop aGVHD,and the absolute count of CD8+CD28-T cells can be used to predict the incidence of aGVHD to some extent.The absolute count of CD8+CD28-T cells after haplo-HSCT was not associated with cGVHD,fungal infection,EBV infection,and CMV infection,and was also not significantly associated with the prognosis after transplantation.

Objective:To investigate the clinical efficacy of extracorporeal shock wave (ESWT) combined with stretching training in the treatment of chronic plantar fasciitis.Methods:A prospective case-control study was conducted to include the patients with chronic plantar fasciitis who had been admitted to Department of Orthopaedic Trauma, Nanfang Hospital, Southern Medical University from June 2021 to June 2022. A SPSS random number generator was used to randomize the patients into an experimental group (receiving treatment with ESWT combined with stretching training) and a control group (receiving stretching training only). Shear wave elastography (SWE) was used to quantitatively evaluate the elastic modulus of the plantar fascia. The 2 groups were compared in terms of visual analogue scale (VAS) pain score, plantar fascia thickness, and elastic modulus of the plantar fascia in the patients at 12 weeks after treatment; the correlation between VAS pain score and elastic modulus of the plantar fascia was examined using Spearman analysis in the patients at 12 weeks after treatment.Results:This study included a total of 41 patients (52 feet), 20 males and 21 females with an age of (49.9±8.2) years. There were 16 left sides, 14 right sides and 11 bilateral sides affected. The course of the disease was 7.0 (6.0, 12.0) months. The 2 groups were comparable because there were no significant differences in the general data before treatment between them ( P>0.05). The VAS pain score at 12 weeks after treatment for the experimental group was 1.0 (1.0, 2.0) points, significantly lower than that for the control group [3.0 (2.0, 3.0) points] ( P<0.05). The elastic modulus of the plantar fascia at 12 weeks after treatment for the experimental group was (79.48 ± 17.65) kPa, significantly higher than that for the control group [(57.08 ± 14.16) kPa] ( P<0.05). However, there was no statistically significant difference between the 2 groups in the thickness of the plantar fascia at 12 weeks after treatment ( P>0.05). There was a significant correlation between VAS pain score and elastic modulus of the plantar fascia after 12 weeks of treatment ( r = -0.708, P<0.001). Conclusion:In the treatment of chronic plantar fasciitis, combination of ESWT and stretching training is more effective than stretching training only.

Traditional Chinese medicine(TCM) has been treating diseases for thousands of years and still holds an irreplaceable position in modern disease treatment. The composition of TCM is complex, and its mode of action features multi-pathway and multi-target characteristics, making its pharmacological actions and mechanisms complicated. The principles and mechanisms of TCM have always been a hot topic among scholars from various fields. Increasingly, studies show that indirect action plays an important role in the mode of action of TCM. The gut microbiota is regarded as a new invisible metabolic organ, and TCM can treat diseases by targeting the gut microbiota, thereby exerting an indirect effect across organs based on the connection between organs. Therefore, this paper summarized the indirect regulatory mechanisms of TCM based on the visceral manifestation theory and the organ axis of modern medical research. It also discussed the talks and communication mechanisms between the gut microbiota and target organs such as the liver, brain, kidney, and lungs, providing references for research on the mechanisms of indirect action of TCM and the development of innovative drugs.
