Objective: To study difference of the immune response between oral administration and intraperitoneal injection of total polysaccharide of Sijunzi decoction (SJTP) in mice. Methods: The immunosuppressed mice model was established by intraperitoneal injection of cyclophosphamide (CY). The effects of SJTP on the weight of immune organs,hemolysin response and delayed type hypersensitivity (DTH) were observed,and the influences on normal mouse spleen lymphocytic proliferation of mice were also studied. Results:SJTP can remarkably counteract the immunosuppression induced by CY, decrease the weight loss immune organs,increase the hemolysin response and DTH,and promote the proliferation of lymphocytes.The effect of oral administration is superior to intrapertoneal injection.Conclusion:SJTP can improve the humoral and cellalar immunity of mice.The immune activities resulting from oral administration of SJTP have some special characteristics,and its possible mechanism is also discussed.

OBJECTIVETo establish a SPE-HPLC method for analyzing astilbin in rats serum and explore the effects of Yinxieling (YXL) prescription and Smilacis Glabrae Rhizoma on the pharmacokinetic characteristics of effective components.
METHODMale Sprague-dawley rats were administrated YXL and Smilacis Glabrae Rhizoma respectively. At different time points, serum concentration of astilbin was extracted by Solid Phase Extraction (SPE) and determined using HPLC method. Chromatographic separation was achieved on a reversed-phase Phenomenex C18 column with the mobile phase of methanol-acetonitrile-formic acid water solution (0.05% formic acid) and gradient elution, temperature of bar was 24 degrees C, flow rate was 0.8 mL x min(-1).
RESULTThe method showed excellent linearity over the concentration range 0.266-53.1 mg x L(-1) of astilbin (r = 0.996). The extract recoveries were from 79.0% to 89.1%. Significant diffenerce in pharmacokinetic parameter of astilbin including t1/2, Cmax, AUC(0-t), AUC(0-infinity) and MRT were obtained through non-compartment model after oral administration of YXL prescription comparing with Smilacis Glabrae Rhizoma.
CONCLUSIONThe method was applied to a pharmacokinetic study of astilbin. It indicated that the bioavailability of astilbin in YXL enhanced in rats and one of the reasons may be that components of prescription affect the pharmacokinetics of astilbin in vivo.

Objective· To evaluate the safety of neoadjuvant therapy which was constituted by docetaxel based systemic chemotherapy and maximal androgen blockage for patients with locally advanced prostate cancer and to summarize the related adverse events and clinical managements.Methods· From June 2015 to February 2017,the clinical data of 55 patients undergoing neoadjuvant chemotherapy combined with complete androgen deprivation were retrospectively reviewed.The patients were given docetaxel and prednisone as DP regimen every 3 weeks and LHRH analogues with bicalutamide as maximal androgen deprivation for a total of 4 cycles.All treatment-related adverse events were observed and then recorded.Results· Two cases with liver function impairment after 2 cycles of treatment were withdrawn from the study.No severe allergic reactions occurred during neoadjuvant therapy.The most common adverse events were hematologic toxicity,while 23.6% of patients had grade Ⅲ-Ⅳ neutropenia,and about 12.7% had anemia.Due to a relatively short course of treatment,the skin or mucous damage,peripheral neurotoxicity and fluid retention were rare.However,hot flash,male breast development as well as erectile dysfunction were very frequently observed due to maximal androgen deprivation.The majority of these adverse events were relieved by symptomatic and supportive treatment.Conclusion · After strict selection,4 cycles of neoadjuvant chemotherapy combined with total androgen blockade could be well tolerated by the patients with high-risk locally advanced prostate cancer.Even though the adverse events were controllable,they still need to be closely monitored during treatment in order to reduce the incidence.In addition,the very low testosterone level associated endocrinal metabolic disorders caused by complete androgen deprivation were also of great concern.

Mammalian reproduction is closely related to their metabolic status. The hypothalamus-pituitary-gonad axis ( HPG axis) is regulated by various metabolic factors. Glucagon-like peptide-1 ( GLP-1) is one of various metabolic factors that not only affect glycemic and metabolic control, but also with many other effects, including affecting HPA axis. The function of GLP-1 is related to the location of glucagon-like peptide-1 receptor ( GLP-1R) distribution. It has been confirmed that GLP-1R is widely distributed in HPG axis. The effects of GLP-1 and GLP-1R agonists on the HPG axis have also attracted much attention. The positive effects of GLP-1 and GLP-1R agonists on the HPG axis indicated it could be the new target for the new treatment for gonadal diseases. The role of GLP-1 and GLP-1R agonists in the central nervous system is reviewed.

Patients with spinal cord injury is associated with seriously affected gastrointestinal function and imbalance of intestinal flora, leading to increased inflammation of spinal cord nerves. With the proposal of the theory of gut microbiota-gut-brain axis in recent years, the regulatory role of gut microbiota in the central nervous system and gastrointestinal system has gradually attracted attention. Although a considerable number of studies have focused on the effects of intestinal flora characteristics on spinal cord nerve function repair in patients with spinal cord injury from different perspectives, there are numerous research models for treating spinal cord injury with intestinal flora as intervention targets and remains a lack of unified and effective clinical treatment methods. In this paper, the authors review the research progress in characteristics of intestinal microflora and intestinal microflora-targeted therapeutic methods in patients with spinal cord injury, hoping to provide a reference for the clinical treatment and basic research of spinal cord injury.

Purpose:
In non-metastatic prostate cancer (nmPCa) setting, it is important to early identify the patients at risk of biochemical recurrence (BCR) for immediate postoperative intervention. Our study aimed to evaluate the potential clinical utility of circulating tumor DNA (ctDNA) for predicting disease recurrence.
Materials and Methods:
This real-world observational study evaluated 161 cases of nmPCa undergoing next-generation sequencing at our institution. A total of 139 ctDNA samples and 31 biopsied tumor tissue underwent genomic profiling. The study endpoint was BCR after radical prostatectomy. Relationships between the ctDNA status and the biochemical progression-free survival (bPFS) were analyzed by log-rank test and multivariate Cox regression.
Results:
Of 161 enrolled patients, 19 (11.8%) harbored deleterious alterations in NCOR2, followed by BRCA2 (3.7%), ATR (2.5%), and CDK12 (2.5%). Of available pre-operative blood samples (n=139), ctDNA was detectable in 91 (65.5%). Until last follow-up, 56 of 68 patients (85.3%) with detectable ctDNA had achieved BCR, whereas only eight of 39 patients (20.5%) with undetectable ctDNA had achieved BCR. Patients who had undetectable ctDNA experienced significantly longer bPFS compared with those who had detectable ctDNA (not available vs. 8.2 months; hazard ratio, 0.14; p < 0.01). Pre-operative ctDNA status was a significant prognostic factor of disease recurrence.
Conclusion
Pre-operative ctDNA detection could identify patients at high risk of recurrence and has the potential to inform immediate postoperative interventions, but these approaches remain to be validated in prospective studies. ctDNA studies can provide insights into accurate monitoring and precise treatment rather than simply following routine clinical care.

Objective:To investigate alterations in functional connectivity network and brain function activity in childhood absence epilepsy (CAE) based on neuromagnetic signals by using multi-frequency magnetoencephalography.Methods:Twenty-five drug-naive children diagnosed with CAE from the Affiliated Brain Hospital of Nanjing Medical University and the Affiliated Children′s Hospital of Nanjing Medical University during October 2022 and March 2024 and 25 healthy controls matched for age and sex from community were recruited in this cross-sectional study. The interictal data, ictal data of CAE and healthy control children were collected using a CTF-275 channel magnetoencephalography system. Corrected amplitude envelope correlation was used to construct functional connectivity network, and network-based statistics were used to compare network differences between groups. Relative power spectral density was used to describe the distribution characteristics of whole-brain spectral power. Nonparametric permutation tests were conducted 1 000 times to compare spectral power differences between groups.Results:In terms of functional connectivity, significant increases in network activity were observed in the low-frequency bands (δ, θ) during interictal periods in children with CAE. A sub-network with significantly increased functional connectivity, including key nodes of the default mode network, was observed in the δ band. Compared with interictal periods, functional connectivity in the δ band decreased during absence seizures in children with CAE, while connectivity in the mid-to-high-frequency bands (α-γ2) increased. In terms of spectral power, children with CAE during interictal periods exhibited widespread magnetic source activation in the δ band, activation in parts of the parietal and occipital lobes in the θ band, and significantly decreased magnetic source intensity in most areas of the parietal, occipital, and temporal lobes in the α-γ2 band. Compared with interictal periods, children with CAE during absence seizures exhibited widespread magnetic source activation in the δ band, and significantly decreased activation in the θ-γ2 band. According to the magnetic source distribution map, during absence seizures, the frontal lobe replaced the parieto-occipital region in cortical activation in the α band.Conclusion:In the analysis of functional network and spectral power based on multi-frequency neuromagnetic signals, the network pattern and magnetic source activation of children with CAE during interictal periods were significantly different from those of healthy children, and there were characteristic changes in neuromagnetic signals during consciousness impairment caused by absence seizures in children with CAE.
