Objective To investigate the therapeutic effects of Jiaotai Pill(JTP)on type 2 diabetic(T2DM)rats,a systemic study was conducted by examining the changes in neurotransmitter levels related to the hypothalamic-pituitary-adrenal(HPA)axis.Methods The rats were divided into a normal group,a model group,a metformin group(183 mg·kg-1·d-1),and a JTP treatment group(3.3 g·kg-1·d-1).A T2DM model was established using a high-fat diet combined with streptozotocin.After 28 days of intragastric administration of JTP and metformin,metabolic indicators,Fasting blood glucose(FBG),insulin(INS),blood lipids,and pathological changes in the liver and kidneys were measured in each group of rats.Levels of eight neurotransmitters were quantified in serum,urine,and multiple tissues(brain,heart,liver,kidney,intestine,and adrenal gland)using ultra-high-performance liquid chromatography-tandem mass spectrometry.Results Compared to the T2DM model group,the JTP intervention groups showed varying degrees of reduction in water intake,food intake,FBG,INS,and blood lipids(P<0.05).Additionally,the fatty degeneration in the liver,glomerular lesions in the kidneys,and dyslipidemia were significantly improved.JTP intervention significantly modulated the disordered neurotransmitter levels in the blood,urine,and various tissues of T2DM rats(P<0.05),with the greatest number of neurotransmitters showing a notable recovery in blood,urine,brain,and adrenal gland.Conclusion JTP at a dosage of 3.3 g·kg-1·d-1 can improve the glucose and lipid metabolism in rats.JTP can regulate the HPA axis-related neurotransmitter system,mitigating metabolic disturbances and organ damage associated with T2DM.

Objective:To investigate the relationship between empathy and meaning in life among medical students,and explore the mediating role of altruistic behavior.Methods:A total of 581 medical students were recrui-ted.They were assessed with the Interpersonal Reactivity Index-C(IRI-C),Altruistic Behavior Questionnaire of College Students(ABQ-CS),and Quadripartite Existential Meaning Scale(QEMS).The bootstrap method was used to test the hypothesized mediating effect.Results:The scores of IRI-C were positively correlated with the scores of ABQ-CS and QEMS(r=0.45,0.21,Ps＜0.001).The scores of ABQ-CS were positively correlated with the QEMS scores(r=0.46,P＜0.001).Altruism was a complete mediator between empathy and meaning in life,the indirect effect was 0.20(95％CI:0.15-0.26).Conclusion:This study reveals the underlying connections a-mong altruistic behavior,empathy,and meaning in life among medical students,suggesting that interventions targe-ting empathy and altruistic behavior may enhance their meaning in life.

Objective:To elucidate the genomic characteristics of the immunoglobulin (IG) heavy-chain variable region and light-chain variable region, the expression of subclones, and the prognostic significance in patients with CLL.Methods:Blood and/or bone marrow specimens were gathered from a cohort of 36 patients with CLL diagnosed at Jiangsu Province Hospital from December 2018 to May 2023, including 12 cases of B cell receptor (BCR) stereotyped patients. IG heavy-chain (IGH) and light-chain (IG Kappa [IGK] and IG lambda [IGL]) gene rearrangements were performed using next-generation sequencing (NGS) technology to analyze the characteristics and prognostic value in CLL.Results:NGS detection of IG variable region (IGHV) demonstrated a significant correlation and superior consistency with Sanger sequencing ( r=0.957, P < 0.001). Among the 36 patients, the IGH variant (IGHV) was observed in 9 (25.0%) but not in 27 (75.0%) participants. The incidence of the MYD88 mutation was higher among patients with mutated IGHV [1/27 (3.7%) vs 4/9 (44.4%), P=0.00]. A high incidence of trisomy 12 was observed in the IGHV #8/#8B subset [4/11 (36.4%) vs 1/25 (4.0%), P=0.023], which were more likely to develop Richter transformation [8/11 (72.7%) vs 4/25 (16.0%), P=0.002]. In the patient cohort, 36 individuals (36/36, 100.0%) used the IGK variable, whereas 15 individuals (15/36, 41.7%) employed the IGL variable (IGLV). IGLV3 - 21 reported the highest utilization rate in IGLV (5/15, 33.3%). Remarkably, patients with CLL with IGLV3-21 fragments were exclusively observed in the Binet C stage and Rai Phase Ⅲ-Ⅳ, with an incidence of del (13) (q14) at 60.0% (3/5). The median time to first treatment (TTFT) of patients with or without IGLV3 - 21 fragments was 5.2 (1.1 - 41.5) and 9.9 (0.1 - 94.4) months, respectively. Using the total reads threshold of 2.5%, 4 (4/36, 11.1%) samples were detected to have two IGHV productive clones. The median TTFT and overall survival (OS) time were 2.8 (0.9-72.7) and 12.8 months in patients with one mutated clone and 57.5 (32.0-120.7) and 51.8 months in those with two mutated clones, respectively. The median TTFT and OS time were 10.9 (0.3-94.4) and 6.3 (0.1 - 12.5) months in patients with one unmutated clone and 49.9 (22.2 - 211.1) and 30.0 (9.6 - 50.3) months in those with multiple unmutated clones, respectively ( P>0.05) . Conclusions:Detection of IG gene rearrangements using NGS technology not only facilitates the analysis of the IGHV mutation status, dominant clones, and prognostic value but also contributes to the exploration of IGK/IGL gene rearrangement fragments and the utilization of subclones. Further, it provides information about the poor prognosis of IGLV3 - 21 CLL. The shortened survival of the two unmutated clone groups in the IGHV unmutated group may indicate a poor prognosis.

Objective:To evaluate the efficacy and long-term outcomes of fludarabine, cyclophosphamide, and rituximab (FCR) in treatment-na?ve patients with chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) .Methods:Clinical data from 68 CLL/SLL patients treated with FCR at Jiangsu Province Hospital (August 2008–May 2021) were retrospectively analyzed to assess efficacy, safety, and survival outcomes.Results:Among 68 patients [46 males, 22 females; median age 55 (47, 60) years], 13.1% (8/61) had a complex karyotype, 32.3% (20/62) had immunoglobulin heavy variable region mutated (IGHV-M) type, 6.6% (4/61) had del (17p), and 14.8% (8/54) had del (11q). Patients received a median of 6 (4, 6) FCR cycles. The overall response rate was 88.2% (60/68), including 47.0% (32/68) complete remissions. Over a median follow-up of 82 (59, 98) months, 66.2% (45/68) experienced disease progression. Median progression-free survival was 56 (21, 123) months, while median overall survival was not reached. The 5- and 10-year PFS rates were 42.6% (95% CI: 31.9–56.8% ) and 28.7% (95% CI: 19.0–43.4% ), respectively. Poor PFS was associated with del (17p) ( HR=5.04, 95% CI: 1.72–14.74, P=0.003), del (11q) ( HR=5.27, 95% CI: 2.11–13.15, P<0.001), IGHV unmutated (IGHV-UM) ( HR=4.11, 95% CI: 1.72–9.79, P=0.001), complex karyotype (CK) ( HR=3.53, 95% CI: 1.58–7.85, P=0.002), β 2-microglobulin >3.5 mg/L ( HR=2.87, 95% CI: 1.37–6.01, P=0.005). In multivariate analysis, IGHV-UM remained an independent predictor of PFS ( HR=8.63, 95% CI: 1.09–68.40, P=0.042). Sixteen patients with IGHV-M and lacking del (17p) or CK had a median PFS of 123 (58,123) months and a 5-year PFS rate of 70.7% (95% CI: 49.7–99.1% ), reaching a plateau after 5 years with no recurrences by 10 years. Common grade 3–4 adverse events included hematologic toxicity (44.1%, 30/68), infection (36.7%, 25/68), and liver dysfunction (4.4%, 3/68). Among 25 patients receiving single-agent BTK inhibitors after FCR progression, median follow-up was 45 (26, 64) months; 36% (9/25) experienced disease progression, with a median PFS time of 55 (27, 55) months. Conclusion:First-line FCR provides durable long-term benefits for patients with IGHV-M CLL without del (17p) or CK.

Chronic pain has emerged as a prevalent medical challenge in contemporary society.Patients suffering from chronic pain frequently develop comorbid psychological disorders,including anxiety,depression,post-traumatic stress disorder,and various psychiatric syndromes.These psychological complications not only affect patients' pain perception and responses,but may also constitute critical obstacles during pain management interventions.Acupuncture is a long-established clinical practice that has demonstrated remarkable efficacy in alleviating diverse pain types and has shown favorable therapeutic outcomes in ameliorating emotional disturbances such as anxiety and depression.The precise mechanisms underlying acupuncture-induced analgesia and anxiolytic effects,however,remain to be fully elucidated.In this context,it is essential to establish suitable and stable animal models to allow in-depth investigations into the pathogenesis of pain-related emotional disorders and the mechanistic foundations of acupuncture.This article presents a comprehensive review of recent literature regarding the selection of experimental animals,model-establishment method ologies,and behavioral-assessment paradigms pertaining to animal model platforms of chronic pain with comorbid anxiety.We also provide an in-depth discussion of research advancements regarding acupuncture intervention parameters,including needling techniques,acupoint selection,treatment duration,and efficacy evaluation within these animal models.This review proposes comprehensive and reference strategies for constructing preclinical animal models to investigate the mechanisms of acupuncture in managing chronic pain with comorbid anxiety,thus supporting scientific advancements in related research fields.

AIM:This study investigated the potential mechanism of acupuncture regulating adenosine A1 re-ceptor(ADORA1)in the mouse caudate putamen(CPu)to improve neuroplasticity and alleviate inflammatory pain.METHODS:Male C57BL/6 mice were randomly divided into five groups,namely,saline,complete Freund's adjuvant(CFA),acupuncture(MA),acupuncture+ADORA1 shRNA(MA+shRNA),and acupuncture+negative shRNA(MA+NCshRNA)groups.Twenty-one days before modeling,the mice in the MA+shRNA and MA+NCshRNA groups were in-jected with ADORA1 shRNA and control virus into the CPu.Modeling was performed 21 d later by injection of CFA into the right plantar skin of mice in the model and acupuncture groups to induce adjuvant-mediated arthritis.On day 2 after modeling,mice in the acupuncture groups received acupuncture at bilateral"Zusanli"points,30 min per session,once a day,for a total of 7 days.The paw thermal radiation pain threshold was used as an indicator of the effects on pain in the mice.Changes in the protein levels of ADORA1,synaptophysin(SYP),synapsin(SYN)I,SYN II,and brain-derived neurotrophic factor(BDNF)in the CPu were assessed by Western blot,and transmission electron microscopy was used to examine the dendritic structure and synaptic ultrastructure of neurons within the CPu.RESULTS:(1)Compared with the saline group,CFA modeling significantly reduced the thermal radiation pain threshold in mice(P<0.01),as well as the protein levels of ADORA1(P<0.01).Compared with the CFA group,the thermal pain threshold in the MA group in-creased between days 1 and 7 of acupuncture(P<0.05 or P<0.01),and ADORA1 protein levels increased(P<0.01).(2)Compared with the saline group,SYN I,SYN II,and BDNF protein levels were increased in the CFA group(P<0.05 or P<0.01),while relative to the CFA group,the levels of SYN I,SYN II,and BDNF were reduced in the acupuncture group(P<0.05 or P<0.01).No significant changes in SYP protein levels were observed in any of the groups.(3)Golgi staining and Sholl analysis showed that compared with the saline group,there were reductions in the total dendritic length and number of intersection points in the CFA group,while the dendritic spine density increased(P<0.05).Relative to the CFA group,the total dendritic length and the number of intersection points were increased in the MA group,while the dendritic spine density decreased(P<0.05).(4)Transmission electron microscopy revealed that compared with the Sa-line group,the synaptic clefts were narrower in the CFA group,while the density of synaptic vesicles in the presynaptic membrane was increased.Compared with the CFA group,synaptic clefts in the MA group were wider,and synaptic vesi-cle densities in the presynaptic membrane were reduced.(5)Twenty-one days after viral transfection,the thermal pain threshold in the MA and MA+NCshRNA groups increased from day 1 to day 7 of acupuncture relative to the CFA and MA+shRNA groups(P<0.05 or P<0.01),while the expression of ADORA1 was increased in both the MA and MA+NCshRNA groups(P<0.05 or P<0.01).(6)Compared with the CFA and MA+shRNA groups,the protein expression of SYN II and BDNF in the MA and MA+NCshRNA groups was reduced(P<0.05 or P<0.01).No significant changes in SYN I protein were observed in any of the groups.CONCLUSION:Acupuncture on Zusanli point can alleviate chronic pain in CFA-treated mice,potentially mediated by up-regulation of ADORA1 expression in the CPu brain region,thereby improving neuroplasticity.

Objective:To investigate the role of umbilical cord mesenchymal stem cell (MSC) -derived nanovesicles in hair regeneration.Methods:(1) Nanovesicles were prepared by continuously extruding umbilical cord MSCs through polycarbonate membranes, and were identified using transmission electron microscopy and nanoparticle tracking analysis. (2) Six C57BL/6 female mice with full-thickness skin wounds were randomly divided into a nanovesicle group (subcutaneously injected with nanovesicles once at the wound margin) and a control group (subcutaneously injected with an equal volume of phosphate-buffered saline [PBS] at the wound margin) ; skin samples were collected on day 16 for hematoxylin-eosin (HE) staining to assess wound healing and hair follicle regeneration. (3) Human hair follicle dermal papilla cells (DPCs) were isolated using a two-step enzyme method; the uptake of PKH26-pre-labeled nanovesicles by DPCs was observed by fluorescence microscopy; the proliferative activity of DPCs co-cultured with nanovesicles was evaluated using cell counting kit-8 (CCK8) and 5-ethynyl-2'-deoxyuridine (EdU) assays. (4) Six healthy C57BL/6 female mice were randomly divided into two groups after anesthesia, and subcutaneously injected with either fluorescent dye DIR-pre-labeled nanovesicles or PBS; an in vivo imaging system was used to observe the uptake and metabolism of nanovesicles in the mouse skin. (5) Twenty-four C57BL/6 female mice with depilated backs were randomly divided into a nanovesicle group (subcutaneously injected with nanovesicles on days 0, 8, and 15) and a control group (subcutaneously injected with an equal volume of PBS at the same time points) ; skin samples were collected on days 4, 18, and 21 for HE staining to analyze differences in hair follicle cycling; transcriptome sequencing was performed on skin samples collected on day 4. Statistical analyses were conducted using the t test. Results:(1) Transmission electron microscopy showed that nanovesicles exhibited a spherical membranous structure with diameters of 141.3 ± 60.0 nm. (2) In 6 C57BL/6 female mice with full-thickness skin wounds, the wound area on day 12 was significantly smaller in the nanovesicle group (1.27 ± 0.50 mm 2) than in the control group (4.13 ± 1.03 mm 2, t = 4.34, P = 0.012). (3) Fluorescence microscopy revealed that nanovesicles were taken up by DPCs within 20 hours; the absorbance of DPCs was significantly higher in the nanovesicle group than in the control group ( t = 20.23, P < 0.001), and the percentage of EdU-positive cells was also significantly higher in the nanovesicle group (49.62% ± 6.45%) than in the control group (37.58% ± 3.42%, t = 3.69, P = 0.006). (4) In vivo imaging of the 6 C57BL/6 female mice showed strong fluorescence in the back of mice in the nanovesicle group on day 0, which markedly decreased by day 8, while no fluorescence was observed in the control group throughout the experiment. (5) Hair follicle cycle experiments on the 24 C57BL/6 female mice with depilated backs showed that the hair follicle length on day 4 after depilation was significantly longer in the nanovesicle group (368.00 ± 63.17 μm) than in the control group (266.90 ± 34.41 μm, t = 9.87, P < 0.001), and the hair bulb diameter was also significantly longer in the nanovesicle group (54.83 ± 10.32 μm) than in the control group (39.12 ± 7.54 μm, t = 16.02, P < 0.001) ; on day 18, the nanovesicle group showed a significantly higher hair follicle density (19.12 ± 0.90) compared with the control group (11.07 ± 1.51, t = 7.92, P = 0.001) ; on day 21, 46.13% ± 8.64% of hair follicles in the nanovesicle group remained in the anagen phase Ⅵ to the catagen phase Ⅱ, and 46.24% ± 3.29% were in the catagen phases Ⅲ to Ⅳ, while 78.89% ± 18.36% of hair follicles in the control group were in the telogen phases Ⅶ to Ⅷ. Transcriptome sequencing showed that differentially expressed genes in the nanovesicle group were significantly positively enriched in the keratinization process (NES = 2.23, P < 0.001) . Conclusion:Umbilical cord MSC-derived nanovesicles could promote the proliferation of DPCs, advance the entry of hair follicles into the anagen phase, delay their entry into the catagen phase, and induce hair regeneration.
