Objective:To investigate the clinicopathological features, mutation, therapeutic efficacy and the factors influencing the prognosis of patients with cardiac diffuse large B-cell lymphoma (DLBCL).Methods:A retrospective case series study was performed. The clinical data of 11 cardiac DLBCL patients in Ruijin Hospital of Shanghai Jiao Tong University School of Medicine from January 2016 to October 2020 were retrospectively analyzed. NovaSeq sequencing platform was used to detect gene mutations in 5 patients, and bioinformatics analysis of sequencing data was conducted through public database to identify the mutation sites of pathogenic genes. Kaplan-Meier method was used to analyze the progression-free survival (PFS) and the overall survival (OS). Univariate Cox proportional risk model was used to analyze the influencing factors of prognosis.Results:Among 11 patients with cardiac DLBCL, 5 were male and 6 were female. The age [ M ( Q1, Q3)] was 61 years (45 years, 70 years). All 11 patients were non-germinal center B-cell (non-GCB) type. There were 2 primary cases and 9 secondary cases; 9 cases with Ann Arbor stage of Ⅲ-Ⅳ, 10 cases with increased lactate dehydrogenase (LDH) and 9 cases with international prognostic index (IPI) score equal to or higher than 3 scores. Among 11 patients, 9 cases received a first-line treatment based on the R-CHOP (rituximab, cyclophosphamide, epirubicin/doxorubicin hydrochloride liposomes, vincristine and prednisone) regimen, of which 8 patients achieved complete remission (CR), and 1 patient achieved stable disease (SD); 1 patient received IR2 (ibrutinib + rituximab + lenalidomide) treatment regimen and achieved SD, and 1 patient received supportive treatment only and achieved progression of the disease. The follow-up time was 39.9 months (25.6 months, 57.3 months). The 3-year PFS rate and 3-year OS rate of 11 patients was 54.5%, 77.9 %, respectively. Univariate Cox regression analysis showed that gender, B symptoms, Ann Arbor stage, LDH level, number of extranodal lesions, IPI score were not correlated with PFS and OS of patients (all P > 0.05). Among 5 cases undergoing gene detection, KMT2D mutations and PIM1 mutations were detected in 2 cases,respectively. Interestingly, KMT2D mutations were only found in secondary cardiac DLBCL patients (2/3), while PIM1 mutations were only detected in primary cardiac DLBCL patients (2/2). Conclusions:Most cardiac DLBCL patients are non-GCB type and have advanced clinical stage, while may benefit from R-CHOP treatment regimen. PIM1 and KMT2D are the commonly mutated genes in cardiac DLBCL.

Objective·To analyze the clinicopathologic characteristics,gene mutation profile,and prognostic factors of thyroid diffuse large B-cell lymphoma(DLBCL).Methods·From November 2003 to December 2021,a total of 66 patients with thyroid DLBCL[23 cases(34.8%)with primary thyroid DLBCL,and 43 cases(65.2%)with secondary thyroid DLBCL]admitted to Ruijin Hospital,Shanghai Jiao Tong University School of Medicine were retrospectively analyzed for their clinicopathological data,survival and prognostic factors.Gene mutation profiles were evaluated by targeted sequencing(55 lymphoma-related genes)in 40 patients.Results·Compared to primary thyroid DLBCL,secondary thyroid DLBCL had advanced ratio of Ann Arbor stage Ⅲ?Ⅳ(P=0.000),elevated serum lactate dehydrogenase(LDH)(P=0.043),number of affected extranodal involvement≥2(P=0.000),non-germinal center B cell(non-GCB)(P=0.030),BCL-2/MYC double expression(DE)(P=0.026),and international prognostic index(IPI)3?5-scores(P=0.000).The proportion of patients who underwent thyroid surgery(P=0.012)was lower than that of patients with primary thyroid DLBCL.The complete remission(CR)rate in primary thyroid DLBCL patients was higher than that in secondary thyroid DLBCL patients(P=0.039).Fifty-five patients(83%)received rituximab combined with cyclophosphamide,doxorubicin,vincristine,and prednisone(R-CHOP)-based first-line regimen.The estimated 5-year progression free survival(PFS)rate of primary thyroid DLBCL patients was 95.0%,higher than the 49.7%of the secondary patients(P=0.010).Univariate analysis showed that Ann Arbor Ⅲ?Ⅳ(HR=4.411,95%CI 1.373?14.170),elevated LDH(HR=5.500,95%CI 1.519?19.911),non-GCB(HR= 5.291,95%CI 1.667?16.788),and DE(HR=6.178,95%CI 1.813?21.058)were adverse prognostic factors of PFS in patients with thyroid DLBCL.Ann Arbor Ⅲ?Ⅳ(HR=7.088,95%CI 0.827?60.717),elevated LDH(HR=6.982,95%CI 0.809?60.266),and DE(HR=18.079,95%CI 1.837?177.923)were adverse prognostic factors of overall survival(OS).Multivariate analysis showed that Ann Arbor Ⅲ?Ⅳ(HR=4.693,95%CI 1.218?18.081)and elevated LDH(HR=5.058,95%CI 1.166?21.941)were independent adverse prognostic factors of PFS in patients with thyroid DLBCL.Targeted sequencing data showed mutation frequency>20%in TET2(n=14,35%),KMT2D(n=13,32%),TP53(n=11,28%),GNA13(n=10,25%),KMT2C(n=9,22%),and TP53 were adverse prognostic factors of PFS in patients with thyroid DLBCL(P=0.000).Conclusion·Patients with primary thyroid DLBCL have better PFS and OS than those with secondary thyroid DLBCL.Ann Arbor Ⅲ?Ⅳ,elevated LDH,non-GCB,and DE(MYC and BCL2)are adverse prognostic factors in thyroid DLBCL.TET2,KMT2D,TP53,GNA13,and KMT2C are commonly highly mutated genes in thyroid DLBCL,and the prognosis of patients with TP53 mutations is poor.

In cardiovascular disorders, neurological diseases, and chronic metabolic diseases, the nuclear factor erythroid 2-related factor 2 (Nrf2) signaling pathway is essential for maintaining cell homeostasis. According to studies, boosting Nrf2 expression can be used to cure or prevent chronic diseases that are characterized by oxidative stress, inflammation, and mitochondrial dysfunction. Nonalcoholic fatty liver disease (NAFLD) is a chronic metabolic liver disease characterized by hepatic steatosis brought on by a number of causes other than alcohol. In recent years, its incidence has gradually risen across the globe. According to relevant studies, NAFLD and the Nrf2 signaling pathway are tightly connected. Inhibiting lipid production and metabolism-related enzymes, repairing impaired liver metabolism, and lowering hepatic lipid storage are all possible with Nrf2 activation. Exercise is a powerful tool for treating and preventing NAFLD. However, exercise type, exercise intensity, environment, and exhaustion all have an impact on the Nrf2 signaling pathway. By activating Nrf2, exercise can lessen liver inflammation, oxidative stress, endoplasmic reticulum stress, and insulin resistance, and ameliorate liver damage to improve NAFLD. The activation of Nrf2 signaling pathway, its associated mechanism of controlling antioxidation, and the impact of exercise on the Nrf2 signaling pathway are all explained in this work. Based on the pathogenesis of NAFLD, this article examines the connection between exercise, Nrf2, and NAFLD, and the current state of knowledge regarding Nrf2’s role in the amelioration of NAFLD through exercise. It offers a theoretical frame of reference for future research into how Nrf2 might be used to improve NAFLD.

Objective To investigate the effect of Xiao Chaihu Decoction and Xiangsha Liujunzi Decoction on the changes of gastric mucosal pathological score and gastrointestinal hormones in patients with chronic atrophic gastritis(CAG)of liver stagnation and spleen deficiency type.Methods A total of 156 cases of CAG patients with liver stagnation and spleen deficiency syndrome were randomly divided into a control group and an observation group,78 cases in each group.The control group was treated with conventional western medicine,and the observation group was treated with Xiao Chaihu Decoction and Xiangsha Liujunzi Decoction on the basis of treatment for the control group.The course of treatment covered four weeks.The changes in the scores of traditional Chinese medicine(TCM)symptoms such as epigastric distention and pain,poor appetite,loose stools,limb weakness,belching and acid regurgitation,gastric mucosal pathological scores and serum levels of gastrointestinal hormones of motilin(MTL)and gastrin(GAS)in the two groups were observed before and after treatment.The negative conversion rate of Helicobacter pylori(Hp)in the two groups was compared,and the clinical efficacy and safety of the two groups were evaluated.Results(1)After four weeks of treatment,the total effective rate of the observation group was 93.59％(73/78),which was significantly higher than 82.05％(64/78)of the control group,and the difference between the two groups was statistically significant(P＜0.05).(2)After treatment,the scores of TCM symptoms such as epigastric distention and pain,poor appetite,loose stool,limb weakness,belching and acid regurgitation in the two groups were significantly decreased compared with those before treatment(P＜0.05),and the decrease in the observation group was significantly superior to that in the control group(P＜0.05).(3)After treatment,the pathological scores of gastric mucosa in the two groups were significantly decreased when compared with those before treatment(P＜0.05),and the decrease in the observation group was more significant than that in the control group(P＜0.01).(4)After four weeks of treatment,the negative conversion rate of Hp in the observation group was 91.03％(71/78),which was significantly higher than that in the control group(75.64％,59/78),and the difference between the two groups was statistically significant(P＜0.05).(5)After treatment,the level of serum GAS in the two groups was significantly decreased(P＜0.05)and the serum MTL level was significantly increased compared with that before treatment(P＜0.05);the decrease of serum GAS level and the increase of serum MTL level in the observation group were significantly superior to those in the control group(P＜0.05).(6)There were no obvious abnormalities in the routine test of blood,urine,stool,kidney function,and liver function,electrocardiograph and other safety indicators during the treatment of the two groups of patients,no adverse reactions such as dizziness,rash and chest distress occurred either,with high safety.Conclusion Xiao Chaihu Decoction combined with Xiangsha Liujunzi Decoction exerts a significant therapeutic effect on GAS of liver stagnation and spleen deficiency type,which can effectively relieve the clinical symptoms,improve the pathological changes of gastric mucosa and promote Hp negative conversion.The therapeutic mechanism may be related to the regulation of gastrointestinal hormone levels.

Objective To investigate the clinical characteristics and prognosis of pneumococcal meningitis(PM),and drug sensitivity of Streptococcus pneumoniae(SP)isolates in Chinese children.Methods A retrospective analysis was conducted on clinical information,laboratory data,and microbiological data of 160 hospitalized children under 15 years old with PM from January 2019 to December 2020 in 33 tertiary hospitals across the country.Results Among the 160 children with PM,there were 103 males and 57 females.The age ranged from 15 days to 15 years,with 109 cases(68.1% )aged 3 months to under 3 years.SP strains were isolated from 95 cases(59.4% )in cerebrospinal fluid cultures and from 57 cases(35.6% )in blood cultures.The positive rates of SP detection by cerebrospinal fluid metagenomic next-generation sequencing and cerebrospinal fluid SP antigen testing were 40% (35/87)and 27% (21/78),respectively.Fifty-five cases(34.4% )had one or more risk factors for purulent meningitis,113 cases(70.6% )had one or more extra-cranial infectious foci,and 18 cases(11.3% )had underlying diseases.The most common clinical symptoms were fever(147 cases,91.9% ),followed by lethargy(98 cases,61.3% )and vomiting(61 cases,38.1% ).Sixty-nine cases(43.1% )experienced intracranial complications during hospitalization,with subdural effusion and/or empyema being the most common complication[43 cases(26.9% )],followed by hydrocephalus in 24 cases(15.0% ),brain abscess in 23 cases(14.4% ),and cerebral hemorrhage in 8 cases(5.0% ).Subdural effusion and/or empyema and hydrocephalus mainly occurred in children under 1 year old,with rates of 91% (39/43)and 83% (20/24),respectively.SP strains exhibited complete sensitivity to vancomycin(100% ,75/75),linezolid(100% ,56/56),and meropenem(100% ,6/6).High sensitivity rates were also observed for levofloxacin(81% ,22/27),moxifloxacin(82% ,14/17),rifampicin(96% ,25/26),and chloramphenicol(91% ,21/23).However,low sensitivity rates were found for penicillin(16% ,11/68)and clindamycin(6% ,1/17),and SP strains were completely resistant to erythromycin(100% ,31/31).The rates of discharge with cure and improvement were 22.5% (36/160)and 66.2% (106/160),respectively,while 18 cases(11.3% )had adverse outcomes.Conclusions Pediatric PM is more common in children aged 3 months to under 3 years.Intracranial complications are more frequently observed in children under 1 year old.Fever is the most common clinical manifestation of PM,and subdural effusion/emphysema and hydrocephalus are the most frequent complications.Non-culture detection methods for cerebrospinal fluid can improve pathogen detection rates.Adverse outcomes can be noted in more than 10% of PM cases.SP strains are high sensitivity to vancomycin,linezolid,meropenem,levofloxacin,moxifloxacin,rifampicin,and chloramphenicol.[Chinese Journal of Contemporary Pediatrics,2024,26(2):131-138]

Aim To investigate the mechanisms of Chaijin JieYu Anshen formula modulating the depres-sive behaviors and the synaptic plasticity of hippocam-pal neurons in insomnia-concomitant depression rats based on the histone deacetylase 5(HDAC5)/myocyte enhancer factor 2C(MEF2C)pathway.Methods A rat model of insomnia-concomitant depression was es-tablished by PCPA injection combined with chronic un-predictable mild stress(CUMS),and the experiment was divided into the control group,the model group,the high,medium and low dose group of Chaijin JieYu Anshen formula,and the positive drug group.The de-pression of rats was evaluated by sugar-water prefer-ence test,open field test and morris water maze.The levels of 5-hydroxytryptamine(5-HT)and dopamine(DA)in serum were measured by enzyme linked im-munosorbent assay(ELISA).The pathological damage of hippocampal neurons was observed by HE staining and Nissl staining.The damage of dendritic spines of hippocampal neurons was observed by Golgi staining,and the levels of HDAC5,MEF2C,postsynaptic densi-ty-95(PSD-95)and synaptophysin 1(SYN1)in hip-pocampus were measured by Western blot,immunohis-tochemistry and immunofluorescence.Results Com-pared with the model group,the Chaijin JieYu Anshen formula could increase the sugar-water preference rate of the model rats,reduce the immobility time in the open field experiment,increase the total activity dis-tance,shorten the evasion latency in the localization navigation experiment,and prolong the residence time in the quadrant where the platform was located in the space exploration experiment(P＜0.05,P＜0.01).Moreover,the Chaijin JieYu Anshen formula improved the hippocampal neuron and dendritic spine damage and increase the dendritic branch length and dendritic spine density of hippocampal neurons(P＜0.01,P＜0.01),restore the serum levels of 5-HT and DA in insomnia-concomitant depression rats(P＜0.05,P＜0.01),down-regulate the HDAC5 protein,and up-regulate the expression of MEF2C,PSD-95,and SYN1 protein(P＜0.05,P＜0.01 or P＜0.001).Conclusions Chaijin JieYu Anshen formula may alle-viate the depression-like behavior of model rats by re-ducing the expression of HDAC5 protein,thus deregu-lating the inhibition of transcription factor MEF2C,promoting the expression of PSD-95 and SNY1 protein,and exerting a protective effect on hippocampal neurons and synapses.

Objective·To analyze the clinicopathologic characteristics of patients with kidney-involved diffuse large B-cell lymphoma(DLBCL),including clinical characteristics,pathological characteristics,gene mutation profiles,and prognostic factors.Methods·One hundred and forty-nine patients with kidney-involved DLBCL,admitted to Ruijin Hospital,Shanghai Jiao Tong University School of Medicine from July 2005 to November 2021,were retrospectively analyzed for their clinicopathological data,survival and prognostic factors,which included therapeutic methods,clinical outcomes,staging,etc.Gene mutation profiles were evaluated by targeted sequencing of 54 lymphoma-related genes.Prognostic factors were also analyzed based on the information mentioned above.Results·A total of 149 kidney-involved DLBCL cases were included,of which 89 patients(58.4%)were aged over sixty,121 patients(81.2%)were staged Ann Arbor Ⅲ?Ⅳ,27 patients(18.1%)had an Eastern Cooperative Oncology Group(ECOG)performance status of two or more,121 patients(81.2%)had elevated serum lactate dehydrogenase(LDH)level,111 patients(74.5%)had extranodal invasion in at least two organs and 131 patients(87.9%)scored over 2 points on the international prognosis index(IPI).The estimated 5-year overall survival(OS)rate and progression-free survival(PFS)rate of kidney-involved DLBCL patients were 52.2%and 50.4%respectively.Univariate analysis revealed that elevated serum LDH levels were an adverse prognostic factor for both OS(P=0.048)and PFS(P=0.033).In pathological characteristics,145 patients(97.3%)belonged to DLBCL,not otherwise specified(NOS)and 39 patients(26.3%)belonged to germinal center B-cell(GCB)according to Hans classification.Among 144 patients who could be evaluated for clinical outcomes,87 patients(60.4%)got complete response(CR).Targeted sequencing data from 75 kidney-involved DLBCL patients showed high mutation frequency in PIM1(n=23,31%),MYD88(n=22,29%),CD79B(n=21,28%)and KMT2D(n=18,24%),with CD79B mutation indentified as an adverse prognostic factor for OS in patients with kidney-involved DLBCL(P=0.034).Conclusion·Elevated serum LDH level is an adverse prognostic factor in patients with kidney-involved DLBCL.The prognosis of patients with CD79B mutations is poor.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Objective: To understand the performance of pulmonary function tests in people aged ≥40 years and its changes in China, and provide evidence for the evaluation of the effect of chronic obstructive pulmonary disease (COPD) prevention and control in China. Methods: The subjects of the survey were from COPD surveillance during 2014-2015 and during 2019-2020, which covered 31 provinces (autonomous regions and municipalities) in China. The survey used multi-stage stratified cluster random sampling method, the trained investigators conducted face-to-face interview to know whether subjects had previous pulmonary function testing or not. Complex sampling weighting was used to estimate the rate of pulmonary function testing in people aged ≥40 years, and the pulmonary function testing rates of the two COPD surveillance periods were compared. Results: A total of 148 427 persons were included in the analysis, including 74 591 persons during 2014-2015 and 73 836 persons during 2019-2020. In 2019-2020, the pulmonary function testing rate in Chinese residents aged ≥40 years was 6.7% (95%CI: 5.2%-8.2%), the rate in men (8.1%, 95%CI: 6.7%-9.6%) was higher than that in women (5.4%, 95%CI: 3.7%- 7.0%), and the rate in urban residents (8.3%, 95%CI: 6.1%-10.5%) was higher than that in rural residents (4.4%, 95%CI: 3.8%-5.1%). The rate of pulmonary function testing increased with the increase of education level. During 2019-2020, the residents with history of chronic respiratory diseases had the highest rate of pulmonary function testing (21.2%, 95%CI: 16.8%-25.7%), followed by the residents with respiratory symptoms (15.1%, 95%CI: 11.8%-18.4%) , the pulmonary function testing rate in those who knew the name of chronic respiratory disease was higher than that in those who did not knew the name of respiratory disease, and the pulmonary function testing rate in former smokers was higher than that in current smokers and non-smokers. Those exposed to occupational dust and/or harmful gases had a higher rate of pulmonary function testing compared with those who were not exposed, and those who used polluted fuels indoors had a lower rate of pulmonary function testing than those who did not use polluted fuels indoors (all P<0.05). Compared with 2014-2015, the pulmonary function testing rate in residents aged ≥40 years in China increased by 1.9 percentage points during 2019-2020, and the rate of pulmonary function testing in groups with different characteristics all increased, and the rates of pulmonary function testing increased by 7.4 percentage points and 7.1 percentage points in residents with respiratory symptoms and in those with history of chronic respiratory diseases (all P<0.05). Conclusions: Compared with 2014-2015, the rate of pulmonary function testing increased in China during 2019-2020 and the increase in residents with history of chronic respiratory diseases and respiratory symptoms was relatively obvious, but the overall pulmonary function testing rate was still at a low level. Effective measures should be taken to further increase the rate of pulmonary function testing.

Objective: To understand the prevalence of smoking and its change in adults aged ≥40 years in China and provide evidence for the development of chronic obstructive pulmonary disease (COPD) prevention and control strategies. Methods: The data of this study were obtained from COPD surveillance in China during 2014-2015 and during 2019-2020. The surveillance covered 31 provinces (autonomous regions and municipalities). A multi-stage stratified cluster random sampling were used to select residents aged ≥40 years, and face-to-face interviews were conducted to collect the information about their tobacco use. After complex sampling weighting of the samples, the current smoking rate, average age to start smoking and average daily cigarette consumption of people with different characteristics during 2019-2020 were estimated, and the changes in the current smoking rate and average daily cigarette consumption were analyzed from 2014-2015 to 2019-2020. Results: During 2019-2020, the current smoking rate in adults aged ≥40 years was 27.2%, and the rate was much higher in men (52.1%) than in women (2.5%).The average age of the smokers to start smoking was 20.0 years old, and men usually started smoking at younger age (19.6 years) compared with women (27.9 years). The average daily cigarette consumption of daily smokers was 18.0 sticks, and the consumption of men (18.3 cigarettes) was higher than that of women (11.1 cigarettes). Compared with the surveillance results during 2014-2015, the current smoking rate had decreased by 2.8 percentage points in the general population, 4.1 percentage points in males, 1.6 percentage points in females, and the urban and rural areas fell by 3.1 percentage points and 2.5 percentage points, respectively. The average daily cigarette consumption decreased by 0.6 sticks. Conclusions: In recent years, the current smoking rate and average daily cigarette consumption in adults aged ≥40 years decreased in China, but smoking is still common in more than quarter of this population and more than half of men aged ≥40 years. It is necessary to take targeted tobacco control measures based on population and regional characteristics to further reduce the smoking level of the population.
