ObjectiveTo investigate the therapeutic effects and mechanism of decoctions from four kinds of processed products of Aconiti Radix Lateralis Praeparata（ARLP） in deficiency-cold syndrome. MethodsA total of 36 SD rats were randomly divided into the control group， model group， Shengfupian（SFP） group， Paofuzi（PFZ） group， Heishunpian（HSP） group and Paofupian（PFP） group with 6 rats in each group. Except for the control group， rats in other groups were administered hydrocortisone sodium succinate via intramuscular injection to induce a cold deficiency syndrome model. After 14 consecutive days， each ARLP decoction pieces was administered via continuous gastric lavage at a dose of 12 g·kg^-1·d^-1 for 7 d， while the control and model groups received an equivalent volume of physiological saline. After the end of administration， body weight， spleen weight and thymus weight were measured for calculating the spleen and thymus indexes. Hematoxylin-eosin（HE） staining was used to observe the pathological morphology of adrenal tissue. The fully automatic biochemistry analyzer was used to measure the total cholesterol（TC）， triglyceride（TG）， lactic dehydrogenase（LDH） and lactate（LAC） levels in serum. Enzyme-linked immunosorbent assay（ELISA） was employed to measure the contents of 17-hydroxycorticosteroid（17-OHCS）， cortisol（CORT）， triiodothyronine（T₃）， thyroxine（T₄）， thyrotropin（TSH）， immunoglobulin（Ig） M， IgG， cyclic adenosine monophosphate（cAMP） and cyclic guanosine monophosphate（cGMP）. Western blot was used to measure the protein expression levels of protein kinase A（PKA）， cAMP response element-binding protein（CREB）， silent information regulator 1（Sirt1） and peroxisome proliferator-activated receptor γ coactivator-1α（PGC-1α）. And high performance liquid chromatography（HPLC） was used to determine the content of major alkaloids， followed by Pearson correlation analysis with pharmacodynamic indicators. ResultsAfter modeling， compare with the control group， the model rats exhibited symptoms such as lethargy and loose stools， mild abnormalities were observed in adrenal tissue structure， and both spleen and thymus indices were significantly reduced（P<0.01）. Thyroid， adrenal and immune system functions were suppressed， with decreased serum cAMP level and significantly elevated cGMP level（P<0.01）. Compared with the model group， the adrenal injury by hydrocortisone sodium succinate were repaired and the spleen index were increased significantly in all four ARLP groups（P<0.05， P<0.01）. The thymus index in SFP and PFZ groups were increased significantly（P<0.05）. The contents of T₃， TSH， 17-OHCS and CORT were increased significantly in SFP and PFZ groups（P<0.05）. In addition， the content of IgG in SFP， PFZ and PFP groups were increased significantly（P<0.01）， while the content of IgM in PFZ and HSP groups were also increased significantly（P<0.05）. Regarding the cyclic nucleotide system， PFZ significantly elevated cAMP level while reducing cGMP level（P<0.05）， exhibiting the most pronounced effect among the four decoction pieces. For energy metabolism indicators， PFZ significantly improved abnormal markers including TC， TG， LDH， and LAC（P<0.05）. HSP showed marked improvement effects on TG， LDH， and LAC（P<0.05）. Both PFZ and SFP significantly elevated the expression levels of PKA， CREB， Sirt1， and PGC-1α proteins（P<0.01）. Additionally， the diester alkaloids in ARLP showed a strong positive correlation with TG， IgG， and CORT， a strong negative correlation with LAC， a moderate positive correlation with T₄， and moderate negative correlations with cAMP and spleen index. Monomeric alkaloids showed strong positive correlations with TG and IgG， strong negative correlations with LAC， moderate positive correlations with CORT and T₄， and moderate negative correlations with cAMP and spleen index. However， the content of water-soluble alkaloids showed strong positive correlations with TC， LDH， 17-OHCS， T₃， TSH， and thymus index， moderate positive correlations with cAMP， CORT， T₄， and spleen index， and moderate negative correlation with cGMP. ConclusionAmong different processed ARLP decoction pieces， PFZ processed according to ZHANG Zhongjing's method exhibits the most potent warming and cold-dispelling effects. Its pharmacological actions are mediated through regulating the thyroid， adrenal， immune， cyclic nucleotide systems， and material-energy metabolism pathways. Among these， water-soluble alkaloids show strong or moderate correlations with more indicators of deficiency-cold syndrome and exhibit the highest content in PFZ. Therefore， PFZ processed according to ZHANG Zhongjing's method may exert its warming and cold-dispelling effects through water-soluble alkaloids.

Objective:To investigate the related factors of cognitive impairment in middle-aged and old-aged patients with type 2 diabetes mellitus(T2DM).Methods:A total of 970 patients with T2DM(585 middle-aged group and 385 old-aged group)were selected from residents of a large community in Beijing from September to December 2018.The Mini-Mental State Examination(MMSE)was used to assess the cognitive func-tion.Multivariate logistic regression was used to analyze the related factors.Results:The detection rates of cognitive impairment were 12.0％and 13.5％in middle-aged and old-aged patients with T2DM,respectively.Among mid-dle-aged patients with T2DM,work(OR=0.22,95％CI:0.03-0.77)and education at the junior college or un-dergraduate level and above(OR=0.18,95％CI:0.04-0.55)were protective factors for cognitive impair-ment.Myocardial infarction(OR=4.13,95％CI:1.26-13.63)was a risk factor for cognitive impairment.Among old-aged patients with T2DM,drinking tea 1-2 times a week(OR=0.11,95％CI:0.01-0.58)and education at the junior college or undergraduate level and above(OR=0.19,95％CI:0.05-0.54)were protective factors for cognitive impairment.Stroke(OR=3.64,95％CI:1.55-8.39)and good sleep self-assessment(OR=2.75,95％CI:1.13-7.35)were risk factors for cognitive impairment.Conclusion:Cognitive impairment in middle-aged pa-tients with T2DM is related to work,education level and myocardial infarction,and cognitive impairment in old-aged patients with T2DM is related to lifestyle,education level and stroke.

This report described a case of hereditary thrombotic thrombocytopenic purpura (TTP) with neonatal onset. The infant presented with facial petechiae, jaundice, progressive thrombocytopenia, and persistent bleeding at puncture sites shortly after birth. Plasma ADAMTS13 activity was<1%. Whole-exome sequencing identified heterozygous variants in ADAMTS13: c.3121C>T and c.1869delT, inherited from the father and mother, respectively. The infant improved following exchange transfusion and phototherapy. Post-discharge, prophylactic fresh frozen plasma infusion was administered every 3-4 weeks. At the 2-year follow-up, no abnormalities were observed. This case highlights the importance of early recognition and intervention in neonates with unexplained thrombocytopenia, severe non-hemolytic jaundice, and anemia to ensure survival and improve prognosis.

AIM:To investigate the potential of resveratrol(Res)to alleviate cerebral ischemia-re-perfusion injury(CIRI)by activating autophagy.METHODS:One hundred SD rats were purchased and subjected to middle cerebral artery occlusion/reperfusion(MCAO/R)using the suture method.Rats with failed surgeries were excluded,and they were randomly divided into seven groups:Sham(S)group,Model(M)group,Resveratrol pretreatment(Res)group,3-methyladenine(3-MA)group,Resve-ratrol+3-methyladenine(Res+3-MA)group,Z-YVAD group,and Res+Z-YVAD group,with 12 rats in each group.Neurological deficits and brain dam-age were assessed using Longa scoring,TTC stain-ing,and measurement of infarct volume.Immuno-histochemistry,immunofluorescence,and immu-noblotting were employed to detect the expression of autophagy-related proteins Beclin-1,LC3-Ⅱ,P62,and pyroptosis-related proteins NLRP3,caspase-1,GSDMD,IL-1β.RESULTS:Resveratrol pretreatment improved neurological deficits and reduced infarct volume in rats.It upregulated autophagy-related proteins Beclin-1,LC3-Ⅱ,downregulated P62,and pyroptosis-related proteins NLRP3,caspase-1,GSD-MD,IL-1β expression.The autophagy inhibitor 3-MA completely reversed the above effects of Res.After adding the pyroptosis inhibitor Z-YVAD,the changes in autophagy-related proteins Beclin-1,LC3-Ⅱ,and P62 were not significant,while the ex-pression of NLRP3,caspase-1,GSDMD,IL-1β signifi-cantly decreased.Neurological deficits worsened,and infarct volume increased in rats.CONCLUSION:Res attenuates cerebral ischemia-reperfusion injury by activating autophagy and inhibiting pyroptosis,possibly through the regulation of the P62.

Objective:To explore the mechanism of pterostilbene(PTE)in preventing and treating neuroinflamma-tion after cerebral ischemia-reperfusion injury(CIRI)in rats.Methods:Ninety male SD rats were randomly divided in-to a sham group,a model group(MCAO/R),a low-dose PTE group(PTE-L),a medium-dose PTE group(PTE-M),and a high-dose PTE group(PTE-H).CIRI model was prepared by middle cerebral artery occlusion reperfusion(MCAO/R)in rats.The neurological deficit in rats was evaluated by Zea Longa score.The volume of cerebral infarc-tion was detected by TTC staining.The morphological changes of ischemic cortex was observed HE staining.The ex-pressions of cyclooxygenase-2(COX-2),prostaglandin D2 receptor(DP2)and prostaglandin D1 receptor(DP1)were detected by RT-qPCR and Western Blot.The expressions of prostaglandin D2(PGD2),interleukin-1 β(IL-1β)and tumor necrosis factor-α(TNF-α)were detected by ELISA.Results:Compared with the sham group,the MCAO/R group showed a significant increase in neurological scores(P＜0.05),a significant increase in cerebral infarction vol-ume(P＜0.05),and aggravated cortical damage in the ischemic area.Additionally,there were significant increase in the expressions of COX-2,DP2 mRNA and protein(P＜0.05),along with increased expressions of PGD2,IL-1β and TNF-α(P＜0.05).Compared with the MCAO/R group,the PTE-L,PTE-M,and PTE-H groups showed a significant decrease in neurological scores(P＜0.05),a significant decrease in cerebral infarction volume(P＜0.05),and markedly alleviated cortical damage in the ischemic region.Additionally,there were significant decrease in the expres-sions of COX-2,DP2 mRNA and protein(P＜0.05),along with decreased expressions of PGD2,IL-1β and TNF-α(P＜0.05).Furthermore,a dose-effect relationship was observed for the neuroprotective effects of PTE on brain tissue(P＜0.05).However,there were no significant differences in the expressions of DP,mRNA and protein among all groups(P＞0.05).Conclusion:PTE can attenuate the neuroinflammation of CIRI in rats by inhibiting COX-2/PGD2/DP2 signaling pathway.

Background:Esophageal neuroendocrine neoplasms(E-NENs)are rare and highly aggressive malignancies.Although endoscopic resection(ER)has demonstrated efficacy in managing gastrointestinal neuroendocrine tumors,ER for E-NENs lacks systematic evidence.Aims:To evaluate the feasibility and safety of ER in E-NENs,establish risk-stratified follow-up strategies based on tumor grade,invasion depth,and margin status,and define indications for ER.Methods:A retrospective analysis was conducted for 8 E-NEN patients treated with ER at the Endoscopy Center,Zhongshan Hospital,Fudan University from November 2017 to July 2021.The clinicopathological data,procedural parameters,adverse events,and follow-up outcomes were collected to summarize the diagnostic and therapeutic insights.Results:The cohort included 8 patients,with male-to-female ratio of 1:1;the mean age was(71.4±8.5)years.Half of the cases were incidentally detected during asymptomatic endoscopic screening.All tumors were confined to the submucosa:4 were small cell neuroendocrine carcinomas(SCNECs),and 4 were mixed neuroendocrine-non-neuroendocrine neoplasms(MiNENs).Endoscopic submucosal dissection(ESD)was performed in 6 cases and submucosal tunneling endoscopic resection(STER)in 2 cases.Self-limiting fever was reported in one case.One cases required additional surgery due to horizontal margin involving(no recurrence over 67 months follow-up).The median hospitalization was 4.5 days.With a median follow-up of 66 months,the recurrence and all-cause mortality rates were both 25.0%(2/8).Conclusions:MiNENs≤2.5 cm with complete ER exhibit favorable prognoses,whereas SCNECs with high mitotic indices or elevated Ki-67 proliferation indices correlate with poorer outcomes.Post-ER surveillance for E-NENs should meet or exceed esophageal squamous cell carcinoma standards.As the largest single-center ER cohort for E-NENs,this study provides critical evidence for minimally invasive management,though multicenter validation is needed.

Objective:To explore the classification and influencing factors of family resilience and post-traumatic growth in patients with spinal tumor.Methods:A cross-sectional investigation was conducted among 219 inpatients with spinal tumor admitted from July 2021 to July 2022. The General Demographic Information questionnaire, Chinese-Family Resilience Assessment Scale, Posttraumatic Growth Inventory, Family Crisis-Oriented Personal Evaluation Scales (F-COPES), and Social Support Rating Scale (SSRS) were used in the study. The ordinal and multivariate logistic regression analyses was applied to identify the factors associated with the classification of family resilience and post-traumatic growth.Results:Of the 219 patients, there were 62 cases of primary spinal tumors (28.3%). According to the results of latent profile analysis, the respondents were classified into three categories by family resilience and post-traumatic growth, namely family difficulty-resistant type ( n=38, 17.4%), general resilience-struggle type ( n=99, 45.2%) and family adaptation-growth type ( n=82, 37.4%). There were significant differences in occupational status, commitment to housework, family atmosphere( χ2=10.75, P=0.025; χ2=6.95, P=0.031; χ2=11.37, P=0.017), and total score of F-COPES and SSRS ( F=25.95, P<0.001; F=19.06, P<0.001)among three groups. Ordinal and multivariate logisitc regression analyses showed that retirement ( OR=2.928, 95% CI:1.098-7.808, P<0.05), family coping ( OR=1.113, 95% CI:1.063-1.165, P<0.05), and social support ( OR=1.226, 95% CI:1.103-1.362, P<0.05) were independently associated with family resilience and post-traumatic growth in patients with spinal tumor. Conclusion:Patients with spinal tumor have significant differences in characteristics by family resilience and post-traumatic growth. As a result, more targeted interventions should be provided for different categories of spinal tumor patients in the future.
