ObjectiveTo analyze the impact of maternal postpartum depression (PPD) at 2 months postpartum on caregiving for infants aged2 to 24 months, and to provide a scientific basis for future maternal and infant healthcare services. MethodsBased on the Shanghai Maternal-Child Pairs Cohort, 1 060 mother-child pairs were selected from those fully participating in follow-up visits at 2, 6, 12, and 24 months postpartum. Pregnancy and childbirth-related information was collected using standardized questionnaire surveys and hospital obstetric and maternity records. The Edinburgh postpartum depression scale was used to assess the maternal postpartum depressive symptoms at 2 months postpartum. At 2, 6, 12, and 24 months postpartum, questionnaire survey was used to evaluate the maternal responsiveness in caregiving and the provision of early learning opportunities for infants. Scores for responsive caregiving and early learning opportunities at 2, 6, 12, and 24 months were grouped based on the 25th percentile (P₂₅) of total scores. The mixed-effects model was used to analyze the longitudinal impact of maternal postpartum depression at 2 months on the caregiving of 2 to 24-month-old infants. ResultsThe longitudinal results from the mixed-effects model did not show an impact of maternal PPD on infant responsive caregiving within 12 months and early learning opportunities within24 months. However, cross-sectional analysis revealed that, compared to the non-PPD group, the risk of low responsive caregiving at 2 months in the PPD group was 93% higher (OR=1.931, 95%CI: 1.113‒3.364, P=0.019). The risks for low provision of early learning opportunities at2 months and 24 months increased by 59% (OR=1.589, 95%CI: 1.082‒2.324, P=0.017) and 60% (OR=1.598, 95%CI:1.120‒2.279, P=0.010), respectively. ConclusionMaternal postpartum depression increases the risk of low responsive caregiving at 2 months, but its long-term effects warrant further research.

Wilson disease is a copper metabolism disorder caused by mutations in the ATP7B gene， which encodes a copper-transporting ATPase β， and can result in multisystem damage. The kidneys are the third most commonly affected organs after the liver and brain. In recent years， numerous diagnostic and treatment guidelines for Wilson disease have emerged. However， most of these focus primarily on hepatic and neurological manifestations and their management， with limited coverage of renal involvement. The high incidence， low awareness， and lack of clinical specificity of Wilson disease-related renal damage （WDRD） have made early detection and intervention particularly challenging in clinical practice. To further optimize the treatment of patients with WDRD， improve clinical diagnosis and management， and enhance patients' quality of life， the Neurology Committee of the Chinese Association of Integrative Medicine， in April 2024， initiated a revision of the first expert consensus on the integrated diagnosis， treatment， and management of WDRD. This effort brought together experts in hepatology， encephalopathy （neurology）， and nephrology from many tertiary-level grade A hospitals and research institutions across China. Through comprehensive literature review and integration of frontline clinical experience， the expert group jointly developed Chinese Expert Consensus on Integrated Chinese and Western Medicine Management of Wilson Disease-related Renal Damage （hereinafter referred to as the "Consensus"）. This article provides a detailed interpretation of the Consensus in terms of diagnostic criteria， traditional Chinese medicine （TCM） syndrome differentiation and treatment classification， and comprehensive disease management， aiming to better guide clinical application. Regarding diagnostic criteria， the Consensus integrates the latest standards in China and abroad， highlights the importance of biochemical diagnosis， and compensates for the limitations of genetic testing. In the area of TCM syndrome differentiation and treatment， the Consensus refines four major syndrome types， introduces a newly defined syndrome， i.e.， phlegm， blood stasis， and heat accumulation， and elaborates on treatment principles， prescriptions， and clinical modification rules for each syndrome. For comprehensive disease management， the Consensus emphasizes multi-dimensional intervention strategies， including diet， exercise， emotional regulation， medication， and medical care， with the goal of maximally controlling the progression of renal dysfunction and helping patients achieve a better quality of life.

"MS/MS spectrum to structure"plays a critical role in the confirmative identification of complicated matrices and is currently regarded as an extremely challenging endeavor.MS/MS information provides vital clues to structural identification.In this study,a strategy was proposed to facilitate unambiguous identification through matching MS3 with MS2 spectra.Initially,MS3 spectra of the featured ions(c-and y-type ions)generated by the decomposition of ester functional group in esters and the MS2 spectrum of the structural unit([M-H]-)were all captured on the Qtrap-MS platform equipped with two tandem-in-space collision cells,including the second quadrupole cell(q2)and linear ion trap(LIT)chambers(actually the third quadrupole unit).Subsequently,the MS/MS spectrum matching between MS3 spectra of the ester compound and MS2 spectra of the structural unit(s)were achieved.As a result,the findings corresponding to MS3 and MS2 spectra matching were summarized.Finally,based on HR-MS/MS information of total salvianolic acid derivatives(TSA),36 kinds of compounds were preliminarily identified through matching with literature information and database retrieval.The applicability of MS3 and MS2 spectra matching strategy was further justified by the confirmative identification of phenolic acid compounds(Rosmarinic acid and salvianolic acid B)in TSA.Above all,MS3 and MS2 spectra matching strategy was quite meaningful towards advancing"MS/MS spectrum to structure"analysis through recognizing and identifying featured fragment ions,and also provided inspiration and new insights for the structural characterization.

Aim To investigate the effects of hedysar-um polybotrys polysacchcaide(HPS)on gastric muco-sal inflammation of diabetic gastroparesis(DGP)rats and its possible mechanism.Methods A total of 62 male Wistar rats were randomly divided into the control group(12)and the modeling group(50).Except for the control group,the remaining rats were given multi-ple intraperitoneal injections of streptozotocin(25 mg ·kg-1 for three consecutive days)and irregular feed-ing of high-sugar and high-fat diet to replicate DGP model.The model rats were randomly divided into the model group(intragastatically purified water),low,medium and high dose HPS groups(50,100,200 mg ·kg-1·d-1)and the metformin group(90 mg· kg-1·d-1),respectively,and the control group was intragastrically treated with equal volume of purified water once a day for eight weeks.The pathological morphology of gastric mucosa was observed by HE stai-ning;the contents of TNF-α,IL-6,GAS and MTL in gastric mucosa were detected by ELISA.The expres-sion of JAK2 and STAT3mRNA in gastric mucosa was detected by RT-PCR.The levels of JAK2 and STAT3 proteins and their phosphorylation in gastric mucosa were detected by Western blot.Results Compared with the control group,the gastric mucosa of the model group showed a large number of inflammatory cells in-filtrated by HE staining.The contents of TNF-α and IL-6 significantly increased(P＜0.01),while the contents of GAS and MTL significantly decreased(P＜0.01).The mRNA expressions of JAK2 and STAT3 significantly increased(P＜0.05).p-JAK2and p-STAT3 significantly increased(P＜0.01).Compared with the model group,gastric mucosal inflammation was improved in each administration group.The con-tents of TNF-α and IL-6 decreased significantly,while the contents of GAS and MTL increased significantly.The mRNA expressions of JAK2 and STAT3 were sig-nificantly reduced.The expressions of p-JAK2 and p-STAT3 significantly decreased(P＜0.05).Conclu-sions HPS can improve gastric mucosal inflammation and repair gastric mucosal damage in rats,and its mechanism may be related to the regulation of JAK2/STAT3 signaling pathway.

Objective:To investigate the value of 3D CT reconstruction in diagnosis of chronic lateral ankle instability (CLAI) combined with syndesmotic diastasis (SD).Methods:A retrospective study was conducted to analyze the clinical data of 160 patients with CLAI who had been examined by arthroscopy from January 2018 to September 2022 at Department of Foot and Ankle Surgery, Wuhan Fourth Hospital. There were 64 males and 96 females with an age of (39.8±12.6) years. Eighty-one left and 79 right feet were affected; the time from injury to surgery was (27.3±11.6) months. The patients were divided into a widened interval group and a normal interval group according to the syndesmotic width measured, with 2 mm as a critical value. After preoperative 3D CT reconstruction, the differences in anterior tibiofibular distance, posterior tibiofibular distance, the narrowest tibiofibular distance, fibular translation, fibular rotation, and syndesmotic area (SA) were compared between the 2 groups. Univariate and multivariate analyses were performed successively to identify the risk factors. The receiver operating characteristic (ROC) curve was used to identify the best predictive factor and critical value. According to the findings of previous research, the above analyses were repeated to determine the best predictive factor and critical value respectively in the sex subgroup, fibular morphology subgroup and incisura feature subgroup.Results:The binary logistic regression showed that SA was a risk factor for CLAI combined with SD ( OR=1.196, 95% CI: 1.122 to 1.275, P < 0.001). The ROC curve revealed an area under curve of 0.847 and the difference critical value of 22.06 mm 2 that indicated a sensitivity of 80.4% and a specificity of 78.9%, respectively. Subgroup analyses showed that SA was suitable for male and female patients and patients with different fibular morphologies and incisura features but the difference critical values were different. Conclusion:In 3D CT reconstruction, measurement of SA may help the diagnosis of CLAI combined with SD.

Objective:To compare the clinical features and prognosis between newly diagnosed diffuse large B-cell lymphoma(DLBCL)patients with and without hemophagocytic syndrome(HPS).Methods:The clinical data of 45 DLBCL patients in Gansu Provincial Hospital from January 2012 to December 2021 were retrospectively analyzed.The patients were divided into HPS group(15 cases)and non-HPS group(30 cases).The clinical features and prognosis of the two groups were compared,and survival analysis was performed using Kaplan-Meier method.Results:Patients with HSP were mostly characterized by fever,cytopenia and splenomegaly.The levels of ferritin and soluble CD25 increased in all patients.The level of fibrinogen decreased in 66.67％patients,while triglyceride increased in 53.33％patients,and bone marrow hemophagocytosis occurred in 80.00％patients.Compared with non-HSP group,the proportions of patients with advanced stage(Ann Arbor stage Ⅲ/Ⅳ)and lactate dehydrogenase(LDH)≥ 240 U/L were higher in HSP group(both P＜0.05).The median survival time of HSP group was 8.0 months,which was significantly shorter than 45.5 months of non-HSP group(P＜0.001).Conclusion:The DLBCL patients with HPS have later Ann Arbor stage,higher LDH and shorter overall survival time compared with patients without HPS.

Objective:To analyze the prognostic nutritional index(PNI),controlling nutritional status(CONUT)and fibrinogen/albumin ratio(FAR)levels in elderly patients with multiple myeloma(MM)and their prognostic impact.Methods:The clinical data of 74 elderly MM patients diagnosed in Gansu Provincial Hospital from January 2020 to July 2022 were retrospectively analyzed.The optimal cut-off values for PNI,CONUT score and FAR were obtained by receiver operating characteristic(ROC)curve,which were used for grouping patients.The correlation of above three indexes with clinical parameters such as sex,serum calcium(Ca),β2-microglobulin(β2-MG),serum creatinine(Cr)in elderly MM patients were analyzed.The survival rates of patients with different levels of each index were compared.Univariate and multivariate analysis of the impact of clinical indicators on the prognosis of patients were performed.Results:The optimal cut-off values for PNI,CONUT score and FAR were 39.775,3.5 and 0.175,respectively,according to which the patients were divided into high and low group.Statistical analysis showed that there were significant differences in albumin level among different groups(all P＜0.05).In addition,there was a significant difference in hemoglobin between high-PNI group and low-PNI group(P＜0.05),while in sex distribution between high-FAR and low-FAR group(P＜0.05).The survival rate of elderly MM patients with increased PNI,decreased CONUT score and FAR was higher(all P＜0.05).Univariate and multivariate analysis showed that β2-MG,Cr,PNI,CONUT score and FAR were independent prognostic factors for elderly MM patients.Conclusion:PNI,CONUT score and FAR are related to some clinical indicators of elderly MM patients,and have an impact on the prognosis.

Objective:To investigate the clinical characteristics and prognosis of primary bone marrow lymphoma.Methods:The clinical data of 6 patients with primary bone marrow lymphoma admitted to Gansu Provincial People's Hospital from February 2011 to March 2023 were collected,and their clinical characteristics and prognosis were retrospectively analyzed and summarized.Results:The median age of 6 patients was 61(52-74)years old.There were 2 males and 4 females.All patients had fever and abnormal blood routine examination.Physical examination and imaging examination showed no lymphadenopathy,no extranodal lesions in lung,gastrointestinal,liver and spleen,skin,etc.After strict exclusion of systemic lymphoma involvement in the bone marrow,the diagnosis was confirmed by bone marrow examination,5 cases were primary myeloid diffuse large B-cell lymphoma and 1 case was primary myeloid peripheral T-cell lymphoma(NOS).1 case abandoned treatment,5 cases received CHOP-like or combined R regimen,including 1 case of autologous stem cell transplantation.4 cases died and 2 case survived.The median OS was 5.5(1-36)months.Conclusion:The prognosis of primary marrow lymphoma is poor,and bone marrow-related examination is an important means of diagnosis.Diffuse large B-cell lymphoma is the most common histomorphologic and immune subtype,and autologous hematopoietic stem cell transplantation may improve the prognosis.

Objective:To analyze the clinical characteristics and occurrence of thrombotic/bleeding events of patients with myeloproliferative neoplasm(MPN),and explore the main influencing factors,and create a risk prediction.Methods:The clinical data of 126 MPN patients with BCR-ABL fusion gene negative in the Department of Hematology of Gansu Provincial Hospital from January 2016 to September 2021 were collected,and their clinical characteristics,occurrence of thrombotic/bleeding events and main influencing factors were analyzed and summarized retrospectively.Then,a risk prediction model for thrombotic/bleeding events in MPN patients was constructed.Results:Among 126 MPN patients,50 patients(39.7％)had experienced thrombotic/bleeding events,including 44 patients(34.9％)with thrombotic events and 6 patients(4.8％)with bleeding events.Among thrombotic diseases,cerebral thrombosis was the most common(23/44,52.3％),followed by 9 cases of limb artery thrombosis mainly characterized by finger and toe tip artery ischemia,occlusion and gangrene(9/44,20.5％).Bleeding events included intracerebral hemorrhage and gastrointestinal hemorrhage.Univariate analysis showed that hypertension,hyperhomocysteinemia,white blood cell(WBC)≥10 × 109/L,hematocrit(HCT)≥49％,platelet(PLT)≥600 × 109/L and JAK2V617F gene mutation were risk factors for thrombotic/bleeding events in MPN patients,while CALR gene mutation was a protective factor.Multivariate analysis showed that hypertension and PLT ≥ 600 × 109/L were independent risk factors for thrombotic/bleeding events in MPN patients.The goodness of fit of the constructed risk prediction model was 0.872,and the area under the ROC curve was 0.838.The model was validated with clinical data,the sensitivity,specificity and accuracy was 78.85％,87.83％and 84.13％,respectively.Conclusion:The risk of thrombotic/bleeding events in MPN patients with high WBC count,hypertension and hyperhomocysteinemia is higher.Controlling hypertension and hyperhomocysteinemia and reducing WBC and PLT counts are helpful to prevent thrombotic/bleeding events and improve the life quality of patients.

Objective:To explore and analyze the incidence rate,influencing factors and impact on prognosis of pulmonary hypertension(PH)in patients with Philadelphia chromosome negative myeloproliferative neoplasms(Ph-MPNs).Methods:The clinical data of 271 patients with Ph-MPNs were retrospectively analyzed,and different disease subtypes were classified.Patients with different disease types were further divided into PH+and PH-groups according to whether HP occurred.Statistical methods were used to analyze the incidence rate,risk factors,and impact on prognosis of PH in Ph-MPNs patients.Results:The overall incidence rate of PH among 271 patients was 26.9％,and according to the classification of disease subtypes,it was found that the incidence rate of PH in patients with primary myelofibrosis(PMF)was significantly higher than those of patients with polycythemia vera and essential thrombocythemia(both P＜0.05).Multivariate regression analysis showed that advanced age,long disease course,JAK2 positive and increased hematocrit,lactate dehydrogenase,monocyte count,and uric acid level were independent risk factors for PH in Ph-MPNs patients(OR＞1,P＜0.05),and there were some differences in the independent risk factors between different disease subtypes.Survival analysis results showed that the overall survival(OS)rate of PH+patients was significantly lower than that of PH-patients in other types except for PMF(all P＜0.05).Conclusion:The incidence rate of PH in Ph-MPNs patients is high,and its risk factors are diverse.The OS rate of Ph-MPNs patients with PH is low.Therefore,we should be highly alert to the occurrence of PH in Ph-MPNs patients clinically.
