Based on spleen deficiency-phlegm dampness as the core pathogenesis of obesity， and integrating recent advances in modern medicine regarding the key role of immune inflammation in obesity， this paper proposes a multidimensional pathogenic network of "obesity-spleen deficiency-phlegm dampness-immune imbalance". Various traditional Chinese medicine （TCM） herbs that strengthen the spleen， regulate qi， and resolve phlegm and dampness can treat obesity by improving spleen-stomach transport and transformation， promoting water-damp metabolism， and regulating immune homeostasis. This highlights immune inflammation as an important entry point to elucidate the TCM concepts of "spleen deficiency-phlegm dampness" and the therapeutic principle of "strengthening the spleen and eliminating dampness to treat obesity". By systematically analyzing the intrinsic connection between "spleen deficiency generating dampness， internal accumulation of phlegm dampness" and immune dysregulation in obesity， this paper aims to provide theoretical support for TCM treatment of obesity based on dampness.

Pediatric acute liver failure (PALF) is a rare and critical clinical syndrome with a poor prognosis. Its etiology is complex, with a significant proportion of cases having remained classified as indeterminate or cryptogenic PALF. With the application of high-throughput sequencing technologies, a spectrum of disorders caused by specific genetic metabolic defects and characterized by stress-sensitive Recurrent acute liver failure (RALF) has been gradually unveiled, collectively termed Infantile liver failure syndrome (ILFS). Although the molecular mechanisms underlying the subtypes ILFS1, ILFS2, and ILFS3 differ by involving aminoacyl-tRNA synthetase defects, vesicular transport disorders, and autophagy abnormalities, respectively, they share a common clinical phenotype of RALF triggered by fever or infection. This article has systematically reviewed the clinical phenotypic spectrum, molecular genetic characteristics, differential diagnosis strategies, and therapeutic advances of the three ILFS subtypes, with the goal of improving early clinical recognition and precise intervention, and providing an important reference for evaluating the prognosis of different subtypes.

BACKGROUND:Repetitive trans-spinal magnetic stimulation(rTSMS)can inhibit inflammatory responses following spinal cord injury.rTSMS applies magnetic field stimulation to the spinal cord region to modulate neuronal excitability and synaptic transmission,thereby promoting plasticity and repair of the nervous system. OBJECTIVE:To observe the effects of rTSMS on the Toll-like receptor 4(TLR4)/nuclear factor(NF)-κB/NLRP3 signaling pathway after spinal cord injury and explore its mechanism in promoting motor function recovery. METHODS:Male C57BL/6J mice,SPF grade,were randomly divided into sham surgery group,spinal cord injury group,and rTSMS group.The latter two groups of mice were anesthetized and the T9 vertebral plate was removed using rongeur forceps to expose the spinal cord,and the spinal cord was clamped using a small aneurysm clip for 20 seconds to establish the spinal cord injury model.Mice in the rTSMS group underwent a 21-day rTSMS intervention starting on day 1 after spinal cord injury.The stimulation lasted 10 minutes per day,5 days per week with an interval of 2 days.Basso Mouse Scale scores were used to assess motor function recovery in mice after spinal cord injury at 1,3,7,14,and 21 days after spinal cord injury.Western blot was employed to detect the expression of AQP4,apoptotic factors Bax,Bcl-2,CL-Caspase-3,inflammatory factors tumor necrosis factor-α,interferon-γ,interleukin-6,interleukin-4,and the TLR4/NF-κB/NLRP3 signaling pathway related proteins in the injured spinal cord.Oxidative stress assay kit was used to measure the activity of superoxide dismutase,glutathione peroxidase,and malondialdehyde content at the site of spinal cord injury.Immunofluorescence staining was performed to detect the expression of neuronal nuclei(NeuN). RESULTS AND CONCLUSION:The Basso Mouse Scale score in the rTSMS group was significantly higher than that in the spinal cord injury group(P<0.05).Compared with the spinal cord injury group,the rTSMS group showed a reduction in spinal cord water content.The expression of AQP4 protein,malondialdehyde content,and expression of Bax,Bcl-2,CL-Caspase-3,tumor necrosis factor-α,interferon-γ,interleukin-6,and TLR4/NF-κB/NLRP3 signaling pathway related proteins were all decreased in the rTSMS group,while the activities of superoxide dismutase and glutathione peroxidase,as well as the expression of Bcl-2,interleukin-4,and NeuN,were all increased(P<0.05).These results suggest that rTSMS downregulates the expression of proteins related to the TLR4/NF-κB/NLRP3 signaling pathway,alleviating symptoms after spinal cord injury such as spinal cord edema,oxidative stress,apoptosis,and inflammation,exerting neuroprotective effects,and thereby promoting the recovery of hindlimb motor function after spinal cord injury.

Objective:To explore the potential profile characteristics of cancer-related worries in patients after surgery for early-stage lung cancer, and the influencing factors of different categories, provide reference for patients to formulate individualized rehabilitation programs and psychological intervention measures.Methods:A cross-sectional survey method was used to conveniently select patients who received outpatient follow-up after lung cancer surgery at Shanghai Pulmonary Hospital Affiliated to Tongji University from October 2022 to October 2023 as the survey subjects. The general information questionnaire, the Chinese version of Brief Cancer-related Worry Inventory, the Chinese version of the MD Anderson Symptom Inventory, Brief Illness Perception Questionnaire, 10-item Connor Davidson Resilience Scale and Medical Coping Modes Questionnaire were examined. Latent profile analysis was performed on the cancer-related worry scores of lung cancer surgery patients, and its influencing factors were explored by binary Logistic regression analysis.Results:A total of 302 patients after lung cancer surgery were included, including 111 males and 191 females, aged 18-83(52.73 ± 13.07) years, and the Chinese version of the Brief Cancer-related Worry Inventory scored 380.00 (130.00, 720.00) points. The cancer-related worry of patients after lung cancer surgery could be divided into two potential profile categories: "high worry type" (138 patients accounted for 45.70%) and "low worry type" (164 patients accounted for 54.30%). Symptom burden ( OR=1.055, 95% CI 1.039-1.072), illness perception ( OR=1.190, 95% CI 1.127-1.256), resilience ( OR=0.933, 95% CI 0.886-0.983), and coping modes of confrontation ( OR=0.857, 95% CI 0.757-0.971) and acceptance-resignation ( OR=1.247, 95% CI 1.050-1.481) were influencing factors for grouping cancer related worry profiles (all P<0.05). Conclusions:There was significant heterogeneity in the level of cancer-related worries among patients after surgery for early-stage lung cancer. It is recommended that medical staff provide targeted continuity care measures based on the characteristics of worries of different categories of patients to improve patients' postoperative mental health and quality of life.

Obsessive-compulsive disorder (OCD) is characterized by recurrent episodes of intrusive thinking and/or behavior, persistent and variable symptoms, and chronic recurrence. It is clearly recommended in the OCD treatment guidelines that psychotherapy can effectively improve clinical symptoms and play an important role in maintaining long-term efficacy. However, previous research and clinical practice paid little attention to the application of psychological interventions in OCD.Currently, there is insufficient understanding of psychotherapy for OCD, especially the proven first-line exposure and response prevention therapy (ERP), cognitive-behavioral therapy, and Morita therapy.Due to limited resources, they have not received effective intervention. Therefore, this article reviews the relevant research on psychological therapy intervention for OCD in recent years, summarizes the intervention effects of different psychological therapy methods on OCD and further elaborates on possible therapeutic mechanisms.Based on this, combined with the existing research, this article clarifies the effect of various behavioral psychological interventions and their combined treatment, and explores group and online forms of psychological intervention in order to increase the accessibility of psychotherapy for OCD patients.

This paper reports a case of edentulous patient with severe resorption of mandibular alveolar ridge who was treated with tissue conditioner to obtain the shape and marginal position of mandibular personalized denture base,and the final denture was dupli-cated by digital subtraction milling technique.After one year of follow-up,the retention of denture was significantly improved,and there was no soft and hard tissue tenderness or discomfort during mastication.These results suggest that the treatment plan for severe alveolar ridge absorption has clinical application value and promotion potential.

BACKGROUND:While antivenom has provided hope for treating snakebites,it is not always effective for local tissue damage caused by venomous snakes.Additionally,antivenom has several limitations,including the risk of hypersensitivity,immune reactions like"serum sickness,"and accessibility issues in some regions.Consequently,there is an urgent need to explore complementary or alternative therapies and therapeutic targets for snakebites in clinical settings.OBJECTIVE:To observe the effect of the 717 Jiedu Decoction on the expression of extracellular matrix proteins and matrix metalloproteinases/tissue inhibitors of metalloproteinases in the local tissues of rats bitten by Agkistrodon halys.METHODS:SD rats were randomly divided into a control group,a model group,an anti-viper venom serum group,and 717 Jiedu Decoction low-,medium-and high-dose groups.Except for the control group,all other groups received an injection of 1.25 mL/kg of viper venom into the gastrocnemius muscle of the left hind limb to create a model.The 717 Jiedu Decoction low-,medium-and high-dose groups were administered a preventive oral gavage of 1.98,3.96,and 7.92 g/kg daily for seven consecutive days prior to the viper venom injection.The anti-viper venom serum group received a tail vein injection of 0.6 mL of antivenom serum two hours after the venom injection.Twenty-four hours post-injection,the pathological changes in the gastrocnemius muscle were observed using hematoxylin-eosin staining.The expression levels of matrix metalloproteinase-2,matrix metalloproteinase-9,tissue inhibitor of metalloproteinase-1,and tissue inhibitor of metalloproteinase-2 proteins,as well as their mRNA in serum and gastrocnemius muscle,were evaluated using ELISA and qPCR.The expression levels of type Ⅰ collagen,type Ⅳ collagen,fibronectin,laminin,α-smooth muscle actin,transforming growth factor-β1,CD31,and vascular endothelial growth factor in the gastrocnemius muscle were analyzed by immunohistochemistry.RESULTS AND CONCLUSION:(1)Compared to the control group,the model group displayed significant local inflammatory cell infiltration,hemorrhage,muscle structure disruption,and myocyte degeneration and necrosis.The protein and mRNA levels of matrix metalloproteinase-2,matrix metalloproteinase-9,and tissue inhibitor of metalloproteinase-1 in serum and gastrocnemius muscle were elevated(P＜0.05 or P＜0.01),while the mRNA expression of tissue inhibitor of metalloproteinase-2 was reduced(P＜0.01).The protein levels of type Ⅰ collagen and type Ⅳ collagen in the gastrocnemius muscle were significantly decreased(P＜0.01),whereas the protein levels of laminin,vascular endothelial growth factor,and CD31 were increased(P＜0.05 or P＜0.01);however,there were no significant changes in the protein levels of fibronectin,α-smooth muscle actin,and transforming growth factor-β1(P＞0.05).(2)In contrast to the model group,the 717 Jiedu Decoction low-,medium-and high-dose groups and the anti-viper venom serum group demonstrated alleviated myocyte damage,with improved reduction in inflammatory cell infiltration and hemorrhage.The levels of matrix metalloproteinase-2,matrix metalloproteinase-9,and tissue inhibitor of metalloproteinase-1 in serum and gastrocnemius muscle were significantly reduced(P＜0.05 or P＜0.01).In the high-dose 717 Jiedu Decoction group,the protein level of tissue inhibitor of metalloproteinase-2 was upregulated(P＜0.05).Type Ⅰ collagen,type Ⅳ collagen,laminin,α-smooth muscle actin,and transforming growth factor B1 protein expression were elevated(P＜0.05 or P＜0.01),and there was a dose-effect relationship;vascular endothelial growth factor expression was decreased(P＜0.05 or P＜0.01),there was no significant difference in the expression of fibronectin(P＞0.05);the expression of CD31 protein was elevated in the 717 Jiedu Decoction low-dose group(P＜0.01).The results showed that 717 Jiedu Decoction could promote the production of α-smooth muscle actin and transforming growth factor β1 by regulating the expression of matrix metalloproteinase 2,matrix metalloproteinase 9 with tissue metalloproteinase inhibitory factor 1,and tissue metalloproteinase inhibitory factor 2,so as to make the synthesis of extracellular matrix greater than the degradation,maintain the extracellular matrix homeostasis,and then promote the repair of local tissue damage in pit viper bites.

OBJECTIVE To study the levels of serum chitinase-like protein-40(YKL-40),protease-activated recep-tor 1(PAR1)messenger ribonucleic acid(mRNA)and programmed cell death molecule 5(PDCD5)in patients with influenza A virus infection-related pneumonia,and to investigate their relationship with prognosis.METHODS A total of 951 patients with simple influenza A virus infection diagnosed and treated in Linfen People's Hospital from Jan.2022 to Jan.2024 were selected as the influenza A group,166 patients with influenza A virus infection-related pneumonia were selected as the influenza A pneumonia group,963 healthy people who underwent physical examination in the hospital during the same period were selected as the healthy group,and the levels of serum YKL-40,PAR1 mRNA and PDCD5 were compared among the three groups.According to the prognosis of pa-tients with influenza A virus infection-related pneumonia,the patients in the influenza A pneumonia group were di-vided into a good prognosis group(139 cases)and a poor prognosis group(27 cases),the levels of serum YKL-40,PAR1 mRNA and PDCD5 were compared between the two groups,and the predictive value of the combina-tion of the three on the prognosis of patients with influenza A virus infection-related pneumonia was analyzed.RESULTS The levels of serum YKL-40,PAR1 mRNA and PDCD5 in the influenza A pneumonia group were(39.41±7.85)ng/ml,(11.31±3.52)and(3.04±0.89)μg/L,respectively,which were higher than those in the influenza A group[(28.19±5.88)ng/ml,(5.87±1.29),(1.96±0.55)μg/L]and the healthy group,and those in the influenza A group was higher than in the healthy group(P＜0.05).The levels of serum YKL-40,PAR1 mRNA and PDCD5 in the poor prognosis group were(45.73±9.63)ng/ml,(13.20±4.11)μg/L and(3.96±1.32)μg/L,respectively,which were higher than those in the good prognosis group(P＜0.05).The ar-ea under the curve(AUC)of serum YKL-40,PAR1 mRNA,and PDCD5 combined to predict the prognosis of pa-tients with influenza A virus infection-associated pneumonia was 0.840,which was higher than that of the three tests alone(P＜0.05).CONCLUSION The occurrence of influenza A virus infection and its related pneumonia cause elevated levels of serum YKL-40,PAR1 mRNA and PDCD5,and the combination of the three can effective-ly improve the prognostic value of patients with influenza A virus infection-related pneumonia.

Objective:To explore the values of reticulin fiber staining (RFS) in evaluating bone marrow (BM) involvement of lymphoma and in grading of BM biopsy from adult lymphoma patients.Methods:Retrospectively,354 cases of adult lymphoma were collected from November 2023 to May 2024 at Peking University Cancer Hospital. BM samples were stained with RFS and immunohistochemical staining (IHC), and flow cytometry (FCM) was also performed with the BM aspirations simultaneously. RFS was graded according to the European Consensus, as high grade (grade 2-3) indicating BM involvement in the study. BM involvement was considered as definite if no less than two positive findings among IHC, FCM, and RFS. Statistical analyses were performed via SPSS software (V23.0).Results:In this series, 52.3% (185/354) of the patients were male; 35.0% (124/354) aged >60 years; BM involvements were found in 34.5% (122/354) cases with high grade of RFS, which, in turn, were lymphoblastic leukemia/lymphoma (ALL/LBL) group (4/4), indolent B-cell lymphoma (IndBCL) group (49.1%, 53/108), transformed B-cell lymphoma (TrBCL) group (2/5), invasive B-cell lymphoma (InvBCL) group (26.5%, 41/155), T and NK cell lymphoma (TNKCL) group (27.3%, 12/44) and classical Hodgkin lymphoma (CHL) group (26.3%, 10/38); if classified by specific types, T-ALL/LBL (2/2), B-ALL/LBL (2/2) and CLL/SLL (8/10) ranked top three. In terms of the positive rate of BM involvement evaluated by RFS, no significant difference was seen between either gender or age groups ( χ2=3.416, P=0.332 and χ2=4.200, P=0.241); however, significant differences were observed between different lymphoma groups and types ( χ2=29.961, P=0.012 and χ2=102.546, P<0.001, respectively). BM invasion rates indicated by IHC and FCM were 25.4% (90/354) and 13.8% (49/354), respectively. The overall BM invasion rate was 24.3% (86/354), and the sensitivity of RFS, IHC, and FCM was 90.8%, 97.8%, and 55.8%, and specificity was 84.1%, 99.6%, and 98.9%, respectively. Overall, the concordance rate of RFS with IHC and FCM was 83.6% and 74.0%, respectively, including 85.8% and 74.2% for InvBCL group, 79.6% and 75.0% for IndBCL group, 84.1% and 75.0% for TNKCL group, 81.6% and 73.7% for CHL group, 5/5 and 2/5 for TrBCL group, and 4/4 and 3/4 for ALL/LBL group. Conclusions:In the evaluation of BM involvement status of adult lymphoma, high sensitivity and specificity are observed by RFS, and high concordance is also noted with both IHC and FCM. Thus, the BM infiltrating status of adult lymphoma could be evaluated more accurately by a combined usage of the three methods.

Objective To explore the influencing factors of abnormal increase of plasma water-soluble vitamins in patients with parenteral nutrition(PN).Methods A total of 862 hospitalized patients receiving nutritional diagnosis and treatment were enrolled.Daily water-soluble vitamin supply and total urine output were monitored.If patients underwent renal replacement therapy(RRT),the ultrafiltration volume was recorded.Plasma concentrations of nine water-soluble vitamins(Vit-C,B1,B2,B3,B5,B6,B7,B9 and B12)were measured.According to the test results,patients were divided into the accumulation group and the non-accumulation group.Renal function(BUN,Cr,UA),inflammatory indicators(CRP,WBC,NEU,SII)and nutritional indicators(ALB,PA,Hb,LYM)were compared between the two groups.Logistic regression was used to analyze the independent risk factors for the accumulation of water-soluble vitamins.Results There was a high incidence of abnormal plasma water-soluble vitamin levels,including Vit-B2(36.08%),Vit-B6(16.01%)and Vit-B5(13.81%).Compared with the non-accumulation group,the Vit-B2 accumulation group had higher levels of age,BUN,Cr,UA and NEU,and lower levels of ALB,PA and urine volume.The Vit-B5 accumulation group had higher levels of BUN,Cr,UA and NEU,and lower levels of LYM,Hb,ALB,PA and urine volume.Patients in the Vit-B6 accumulation group was older,with increased levels of BUN,Cr and UA,and decreased levels of LYM,Hb,ALB,urine volume and vitamin intake(P＜0.05).Multivariate Logistic regression analysis showed that the elevated level of BUN was independent risk factors for Vit-B2 accumulation,the elevated BUN and reduced urine volume were independent risk factors for Vit-B5 accumulation,and elevated BUN and Cr,as well as reduced urine volume,were independent risk factors for Vit-B6 accumulation.Receiver operating characteristic curve analysis showed that the area under the curve for BUN in predicting Vit-B2,B5 and B6 accumulation were 0.659(95%CI:0.620-0.697),0.728(95%CI:0.675-0.781)and 0.785(95%CI:0.738-0.831),respectively,with high specificity but low sensitivity.Conclusion The serum levels of water-soluble vitamins are affected by renal function.When implementing parenteral nutrition water-soluble vitamins supplementation,the patient's renal function status should be evaluated,and the risk of abnormal elevation of Vit-B2,B5 and B6 should be vigilantly monitored.
