epsis is a systemic inflammatory response syndrome triggered by infection， and its high mortality rate is closely associated with immune imbalance， particularly the imbalance in the differentiation of helper T cell （Th） cell subsets [Th1， Th2， Th17， regulatory T cell （Treg） ] . In recent years， traditional Chinese medicine （TCM）， with its characteristics of multi-component and multi-target actions， has demonstrated unique advantages in regulating Th cell differentiation and function， as well as correcting immune imbalances in sepsis， offering new perspectives for immunotherapy of sepsis. This review summarizes relevant studies on the regulation of Th cell differentiation for sepsis treatment by TCM monomers and active ingredients （such as Astragalus membranaceus ， Scutellaria baicalensis ， Coptis chinensis ， Rheum palmatum ， Ganoderma lucidum ， Ginkgo biloba ， and Cistanche deserticola ）， the alcohol extract of Dai Baijie， and TCM formulas and preparations categorized as blood-activating and stasis-removing， purgative and laxative， warming and tonifying yang， and tonifying qi and nourishing yin. The results indicate that these TCM monomers， active ingredients， extracts， formulas， and preparations can regulate the Th1/Th2 and Th17/Treg balance， target the differentiation balance of Th cell subsets， alleviate inflammatory responses， or improve immune suppression， thereby exerting therapeutic effects on sepsis.

Objective: To conduct screening for rare blood types within important blood group systems for the Chinese population, such as Rh, Duffy, Kidd, P1Pk, Diego, and MNS, in the Guangzhou region, and to establish a corresponding rare blood type database and physical repository. Methods: The saline medium microplate method was used to screen blood donors with the ccDEE phenotype combined with either Jk(a-) or Jk(b-). The polybrene microplate method was employed to screen for donors with Fy(a-), s(-), Lu(b-), Di(b-), k(-), and p phenotypes. The urea lysis microplate method was applied to screen for the Jk(a-b-) phenotype. A high-resolution melting (HRM) curve method was established for screening some donors with the Di(b-) phenotype. Subsequently, expanded phenotyping of antigens in the Rh, Kidd, MNS, Duffy, P1Pk, Lewis, Kell, and Lutheran blood group systems was performed on identified rare blood type donors using monoclonal antibodies. The test results are entered into the Rare Blood Type Bank Management System of the Guangzhou Blood Center, enabling functions such as confirmation reminders and cryopreservation storage when the donor donates again. Red blood cells of rare blood types are processed into frozen red blood cells for long-term storage. Results: Among voluntary blood donors, 16 cases of the ccDEE combined with Jk(a-) phenotype were identified (0.221 7%, 16/7 216); 10 cases of the ccDEE combined with Jk(b-) phenotype (0.138 6%, 10/7 216); 78 cases of the Fy(a-) phenotype (0.169 5%, 78/46 012); 39 cases of the Lu(b-) phenotype (0.138 2%, 39/28 214); 31 cases of the s(-) phenotype (0.081 8%, 31/37 913); 22 cases of the Di(b-) phenotype (0.029 9%, 22/73 691); 30 cases of the Jk(a-b-) phenotype (0.010 1%, 30/298 250); and 1 case of the k(-) phenotype (0.001 3%, 1/77 382), which was further identified as KELnull phenotype (K0). No p phenotype donors were identified (0/88 528). A total of 228 units of frozen red blood cells were prepared. The screening results were compared and analyzed with rare blood type data from other regions. Conclusion: This study, through a combination of different screening methods, significantly improved the efficiency of rare blood type screening while remaining cost-effective. By conducting large-scale screening and performing data informatization processing, a database and physical repository of rare blood types in the Guangzhou region were successfully established. This provides a strong guarantee for the timely supply of blood to patients with difficult-to-match and rare blood types in the region, effectively enhances the level of transfusion safety in the region, and offers a practical paradigm for constructing a comprehensive blood transfusion support system.

Aim To elucidate the molecular mecha-nism underlying the inhibitory effect of liquidambaric acid(LDA)targeting TNF receptor associated factor 6(TRAF6)in colorectal cancer.Methods This study employed microscale thermophoresis(MST),drug af-finity responsive target stability assay(DARTS)and cellular thermal shift assay(CETSA)to confirm the direct binding of LDA to TRAF6.Additionally,we generated TRAF6 knockout colorectal cancer HCT116 cells using CRISPR/Cas9 technology,and assessed the impact of LDA on TRAF6-regulated Hippo/YAP and Wnt signaling pathways through immunofluorescence a-nalysis and TOPFlash/Renilla luciferase reporter sys-tem.Co-IP and proximity ligation assays(PLA)were conducted to investigate LDA-regulated TRAF6 pro-tein-protein interactions and elucidate molecular mech-anisms.Results The direct binding of LDA to TRAF6 was confirmed in cell lysates and living cells.LDA promoted TRAF6-dependent nuclear translocation of YAP in colorectal cancer cells,and inhibited Wnt signaling by overexpressing TRAF6.Co-IP and PLA revealed that TRAF6 formed a tripartite complex with YAP and β-catenin in colon cancer cells,where TRAF6 was a key scaffolding protein of the tripartite complex.LDA disrupted the interactions between the TRAF domain of TRAF6 and YAP,as well as YAP and β-catenin.Conclusion LDA regulates Hippo/YAP signaling pathway by targeting TRAF6 and inhib-its colorectal cancer.

With the establishment of bio-psycho-social medical model,both social and psychological factors play an important role in the occurrence,development and treatment of diseases.Hypertension is a common chronic multiple disease in China,and patients are often complicated with depression and other e-motional disorders.The interaction between hypertension and depression significantly increases the risk of poor prognosis.Current studies have shown a bidirectional promoting relationship between hypertension and depression,and they have some com-mon pathogenesis.However,the specific mechanism of their co-morbidity has not been fully elucidated.Renin-angiotensin sys-tem(RAS)plays an important role in the regulation of hyperten-sion and depression and other emotions.It is composed of two antagonistic pathways.The balance is maintained by angioten-sin-converting enzyme 2(ACE2).Therefore,this article reviews the relationship and mechanism of RAS in hypertension,depres-sion and comorbid states,in order to provide new treatment ide-as for hypertension and depression.

Objective:To observe the influence of acupuncture for regulating the mind and replenishing qi combined with butylphthalide soft capsules on sleep parameters and neurological function in patients with sleep disorders after stroke.Methods:From May 2022 to September 2024,a total of 85 patients with sleep disorders after stroke who were admitted to our hospital were prospectively included,and they were divided into control group(received treatment with butylphthalein soft capsules,42 cases)and study group(received treatment with acupuncture for regulating the mind and replenishing qi combined with butylphthalide soft capsules,43 cases)by the double chromosphere method.Sleep parameters,sleep quality score[pittsburgh sleep quality index(PSQI),insomnia severity index(ISI)],related functional scale score[modified edinburgh scandinavian stroke scale(MMSSS),hospital anxiety and depression scale(HADS),Fugl-Meyer assessment scale(FMA),montreal cognitive assessment(MoCA)]and related serum indicators[hypersensitive C-reactive protein(hs-CRP),tumor necrosis factor-α(TNF-α),5-hydroxy tryptamine(5-HT),gama-aminobutyric acid(GABA)]were compared between the two groups.Result:The total sleep time,sleep efficiency,FMA score,MoCA score,5-HT and GABA indicators in the study group after treatment were higher than those in the control group,the number of awakenings,sleep latency,PSQI score,ISI score,MESSS score,HADS score,hs-CRP and TNF-α indicators were lower than those in the control group(P＜0.05).Conclusion:Acupuncture for regulating the mind and replenishing qi combined with butylphthalide soft capsules can effectively improve the sleep quality of patients with sleep disorders after stroke,regulate the neurological functions,reduce inflammatory factors levels,and improve the motor and cognitive function.

Diabetic nephropathy(DN)is a serious complication of diabetes mellitus and a leading cause of end-stage renal diseases.In DN patients,key pathological mechanisms include proteinuria,glomerulo-sclerosis,and fibrosis,largely driven by poor glycemic control and oxidative stress caused by prolonged hyperglycemia.This stress damages renal podocytes and triggers inflammatory mesenchymal infiltration of renal tubular cells,exacerbating the progression of proteinuria and fibrosis.Human umbilical cord-de-rived mesenchymal stem cells(hUC-MSCs)offer promising potential for treating DN due to their strong anti-oxidative properties.In this study,we developed a DN mouse model and treated the mouse via tail vein injections of hUC-MSCs(1×106 cells/mouse).The results indicated that hUC-MSCs significantly lowered fasting blood glucose levels(22.5±3.0 vs 14.7±1.1,P＜0.01)and improved glucose toler-ance,as shown by intraperitoneal glucose tolerance test(IPGTT)results(P＜0.05).Additionally,the renal function improved in hUC-MSCs-treated mice,with marked reductions in oxidative stress markers,including blood urea nitrogen(BUN),urinary creatinine(Ucr),urinary protein(PRO),superoxide dismutase(SOD),and malondialdehyde(MDA)(P＜0.05).Histological analyses through hematoxy-lin-eosin(H&E),Periodic Acid-Schiff(PAS),and Sirius red staining demonstrated alleviation of glo-merular mesangial hyperplasia,glomerular hypertrophy,and tubular inflammation.Furthermore,hUC-MSCs treatment downregulated the expression of oxidative stress-related proteins,such as NADPH oxi-dase 4(NOX4)and thioredoxin-interacting protein(TXNIP),and reduced reactive oxygen species(ROS)production(P＜0.05).Meanwhile,human renal cortical proximal tubule epithelial cells(HK-2 cells)were selected for validation in vitro experiments using high glucose treatment followed by super-natants of hUC-MSCs(MSC-CM),and Western blotting showed that the expression of both NOX4 and TXNIP was inhibited(P＜0.05)and ROS expression was reduced.In conclusion,hUC-MSC treatment effectively lowered blood glucose levels and improved renal function in DN mice,likely through the sup-pression of NOX4 expression and TXNIP-mediated oxidative stress.

To achieve rapid and visual detection of Plasmodium vivax,a detection method based on recombinase polymerase amplification(RPA)technology and lateral flow dipstick(LFD)was established and evaluated.Targeting the conserved sequence of the P.vivax 18S rRNA gene(GenBank:DQ660817.1)as the target sequence,primers and probes were designed with Primer Premier 5,and the P.vivax recombinant plasmid(pUCPv)was constructed as the standard.A sensitive and specific RPA-LFD-based rapid visual detection method for P.vivax nucleic acids was established.The plasmid standard was serially diluted 10-fold to concentrations of 1×103,1×102,1×101,1×10?,and 1×10?1 copies/μL for sensitivity testing.To evaluate specificity,whole blood DNA samples from patients infected with Plasmodium falciparum,Plasmodium malariae,Plasmodium ovale,or Leishmania donovani,as well as healthy participants,were tested by RPA-LFD.Additionally,The assay′s accuracy was evaluated by testing whole blood DNA samples from 24 confirmed P.vivax-infected patients.This study successfully established a sensitive,specific,and rapid visual RPA-LFD method for detecting P.vivax nucleic acids.The assay can complete P.vivax detection within 20 minutes under isothermal conditions at 39 ℃,achieving a sensitivity of 1 copy/μL.There is no significant cross reaction with parasites such as other Plasmodium species and L.donovani,and the specificity is 100%.All 24 DNA samples from confirmed P.vivax patients were detected,showing a 100%detection rate.The developed RPA-LFD assay exhibits excellent sensitivity and specificity,requires only simple heating equipment,and is user-friendly.This rapid visual detection method is particularly suitable for P.vivax screening in low-resource settings.

Objective:To explore the effects of stepped exercise rehabilitation training on cardiopulmonary function and quality of life in patients with ischemic heart disease.Methods:This randomized controlled study enrolled 110 patients with ischemic heart disease admitted to Jiangsu Province Hospital between January 2021 and December 2023.Patients were randomly divided into control group(n=53,routine intervention program)and intervention group(n=52,additional stepped exercise rehabilitation training).After 3-month intervention,cardiopulmonary function[stroke volume(SV),cardiac index(CI),forced expiratory volume in the first second(FEV1),maximum voluntary ventilation(MVV)],quality of life[China questionnaire of quality of life in patients with cardiovascular diseases(CQQC)score],exercise endurance[exercise duration(ED),peak oxygen intake(VO2peak),anaerobic threshold(AT)]and incidence of major adverse cardiovascular events(MACE)were compared between the two groups.Results:We included 53 patients[28 males(52.83％),age 40～69(56.25±7.76)years old]in control group compared to 52 patients[27 males(51.92％),age 40～71(55.25±2.40)years old]in the intervention group after 3-month intervention.Com-pared to patients in the control group,those in the intervention group had significantly higher SV[(65.46±3.58)ml vs.(61.69±3.78)ml],CI[(2.82±0.12)L·min-1·m-2 vs.(2.54±0.09)L·min-1·m-2],FEV1[(2.50±0.06)L vs.(2.31±0.06)L],MVV[(79.66±0.82)L/min vs.(77.16±1.09)L/min],CQQC score[(65.23±2.84)points vs.(47.98±3.25)points],ED[(382.62±31.19)s vs.(353.37±36.32)s],VQ2peak[(20.05±2.43)ml·kg-1·min-2 vs.(16.86±1.61)ml·kg-1·min-2]and AT[(13.34±0.83)ml·kg-1·min-2 vs.(11.46±0.89)ml·kg-1·min-2](P＜0.001 all),and significantly lower total incidence of MACE(11.54％vs.32.08％,P=0.011).Conclu-sion:Stepped exercise rehabilitation training may improve cardiopulmonary function,quality of life,and exercise endurance in patients with ischemic heart disease during the rehabilitation.

Objective:To construct an integrated management model for early screening and diagnosis of PCa based on the In-novative Care for Chronic Conditions Framework(ICCC)and the 1+1 contract-based tiered diagnosis and treatment system(TDTS)in China.Methods:Based on the 1+1 contract-based TDTS platform,we conducted PCa screening for the male residents aged 60 years and above during health check-ups in Pujin Community Health Center from January 1,2023 to December 31,2023.For those with abnormal total prostate-specific antigen(tPSA)≥4 μg/L,we promptly referred them to higher-level hospitals for further diagno-sis and treatment via the two-way referral green channel platform and information sharing service using the 1+1 contract model.We further analyzed the relevant data on screening and diagnosis.Results:A total of 4 080 males aged 71.39±5.059 years received PCa screening from January to December 2023.PSA screening was performed in 43.96％of the male residents,revealing 654 cases of PSA abnormality,with a PSA positivity rate of 16.03％,which was higher than that found in the previous large-scale PCa screenings in other regions of China.Among the males with PSA abnormality,292(44.65％)expressed their willingness for medical referral,while the others did not seek further medical attention for reasons of being asymptomatic,low awareness of the disease,no accompany for medical visits,and concerns about further costs of diagnosis and treatment.Prostate biopsy was recommended to 154 cases after further examinations,which was accepted by 92(59.74％).Fifty-eight cases were diagnosed with Pa,and thedetection rate reached 63.04％.Conclusion:The integrated management model for PSA examination-based early screening and diagnosis of PCa using the 1+1 contract-based TDTS platform is plays a significant role in enhancing peoples awareness and knowledge of PCa and improving the early detection rate of the malignancy.
