Transfusion and Anemia Expertise Initiative-Control/Avoidance of Bleeding developed a strategy for platelet and plasma infusion management in critically ill children based on systematic reviews and consensus meetings of international multidisciplinary experts. One good practice statement and six expert consensus statements were proposed for plasma and platelet transfusions in critically ill children following severe trauma, traumatic brain injury, and/or intracranial hemorrhage. This article introduces the specific methods and basis for the formation of recommendations in this part of the guide.

ObjectiveTo observe the clinical efficacy of Gandou Fumu Granules （GDFMG） combined with sodium dimercaptosulphonate （DMPS） on liver fibrosis in Wilson disease （WD） patients with the syndrome of phlegm and blood stasis， evaluate its effect on cuproptosis-related indicators， and explore the possible mechanisms of cuproptosis in WD-related liver fibrosis. MethodsSixty WD patients diagnosed with the syndrome of phlegm and blood stasis between January 2023 and December 2023 were randomly divided into a control group and an observation group， with 30 patients in each group. The control group received the copper chelator DMPS for the first 6 days， followed by calcium gluconate injection for the next 2 days， completing an 8-day treatment cycle. The observation group received GDFMG in addition to the treatment regimen of the control group， with both groups treated for 21 cycles. A Beckman fully automated biochemical analyzer was used to detect levels of type Ⅳ collagen （CⅣ）， hyaluronic acid （HA）， laminin （LN）， N-terminal propeptide of type Ⅲ procollagen （PⅢ-NP）， and serum copper （SCu） before and after treatment in both groups. Enzyme-linked immunosorbent assay （ELISA） was used to measure levels of ferredoxin 1 （FDX1）， lipoic acid synthetase （LIAS）， and dihydrolipoamide S-acetyltransferase （DLAT）. Atomic absorption spectroscopy measured 24-hour urine copper levels before treatment and after the 7， 14， and 21 treatment cycles in both groups. An Fibro Touch （FT） non-invasive liver fibrosis diagnostic device was used to measure liver stiffness （LSM） in both groups before and after treatment. Traditional Chinese medicine syndrome score （TCMSS） was evaluated at the same intervals. Clinical efficacy， adverse events， and safety indicators were also compared. ResultsAfter treatment， levels of CⅣ， HA， LN， and PⅢNP significantly decreased in both groups compared to pre-treatment levels （P<0.01）. The observation group showed a more pronounced reduction compared to the control group （P<0.05）. There were no statistically significant differences in SCu levels in both groups before and after treatment. After treatment， levels of FDX1，LIAS and DLAT significantly increased in both groups（P<0.01）. The observation group showed more notable improvements in these indicators than the control group （P<0.05）. After the 7， 14， 21 treatment cycles， 24-hour urine copper levels significantly increased in both groups compared to pre-treatment levels （P<0.01）. The observation group had a greater increase in 24-hour urine copper levels than the control group after treatment （P<0.05，P<0.01）， and although 24-hour urine copper levels increased after 7 cycles， a gradual decline was observed in subsequent cycles. After treatment， LSM levels significantly decreased in both groups compared to pre-treatment levels （P<0.01）， with the observation group showing a greater reduction than the control group （P<0.05）. Clinical efficacy was significantly better in the observation group than the control group （P<0.05）. No significant differences in the incidence of adverse events or safety indicators were observed between the two groups after treatment. ConclusionGDFMG combined with DMPS can reduce LSM in WD patients with liver fibrosis and the syndrome of phlegm and blood stasis， inhibit cuproptosis， and improve clinical efficacy.

Objective To investigate risk factors for residual lesions after initial transurethral resection of bladder tumors(TURBT)and risk factors for tumor recurrence after second TURBT in patients with non-muscle-invasive bladder cancer(NMIBC)in order to provide reference for clinical management.Methods A case-control study design was adopted to include 120 NMIBC patients who underwent initial TURBT and then second surgery within 2～8 weeks in our department from January 2017 to January 2025.Based on the presence of residual lesions after the initial TURBT or not,the patients were divided into a residual lesion group(n=34)and a non-residual lesion group(n=86).Chi-square test and multivariate logistic regression analysis were performed to identify potential risk factors for residual lesions following the initial TURBT.Univariate and multivariate Cox regression models were used to analyze potential risk factors for tumor recurrence after the second TURBT.Results The residual lesion rate after initial TURBT was 28.33％.Chi-square test analysis revealed that tumor stage T1(Chi-square=5.756,P=0.016)and broad tumor base(Chi-square=4.331,P=0.037)were factors influencing residual lesions after initial TURBT.Multivariate logistic regression analysis identified tumor stage T1(OR=3.047,95％CI:1.128～8.226,P=0.028)as an independent risk factor for residual lesions after initial TURBT.The tumor recurrence rate after second TURBT was 17.5％.Multivariate Cox regression analysis identified tumor stage T1(OR=4.258,95％CI:1.248～14.532,P=0.021),intravesical chemotherapy instillation after second TURBT(OR=3.539,95％CI:1.284～9.752,P=0.015),history of urinary system tumors(OR=3.002,95％CI:1.145～7.873,P=0.025)and high platelet-to-lymphocyte(PLR)ratio(OR=2.798,95％CI:1.115～7.023,P=0.028)as independent risk factors for tumor recurrence after second TURBT.Conclusion Tumor stage T1 and broad tumor base are risk factors for residual lesions after initial TURBT,while tumor stage T1,intravesical chemotherapy instillation after second TURBT,history of urinary system tumors and high PLR ratio are risk factors for tumor recurrence after second TURBT.Comprehensive analysis on above 4 indicators can effectively assess the risk of tumor recurrence in NMIBC patients following second TURBT,and timely early medical intervention is beneficial for improving patient outcomes.

Objective Melatonin has been shown to have neuroprotective effects.This study is aimed at observing the effects of copper deposition on cognitive function in a toxic milk(TX)mouse model of Wilson disease(WD),and investigating the effects and mechanisms of action of Gandou Bushen Decoction(GDBSD)on melatonin synthesis and pineal function in the WD model mice.Methods A total of 30 homozygous TX mice were randomly assigned to 3 groups(n=10 in each group),including a WD group,a GDBSD group,and a dimercaptosuccinic acid(DMSA)group.A total of 10 DL mice were included in the normal control(NC)group.The structure and copper content of pineal gland tissues,oxidative stress and apoptosis-related markers,and serum melatonin levels were evaluated using hematoxylin-eosin(HE)staining,enzyme-linked immunosorbent assay(ELISA),flow cytometry,and Western blot.Results Compared with the NC group,the WD group exhibited decreased learning and cognitive abilities(P＜0.05),damaged pineal gland structure,increased copper content,reactive oxygen species(ROS)levels,and mitochondrial damage rate in the pineal gland(P＜0.01),altered levels of melatonin and oxidative stress-related markers(P＜0.05),upregulated expression levels of pro-apoptotic proteins Bax and Caspase-3,and decreased expression of the anti-apoptotic protein Bcl-2(P＜0.01).After treatment with GDBSD and DMSA,the SIRT3/FOXO3α signaling pathway was activated,the copper content in the pineal gland was reduced,and oxidative stress and apoptosis-related damages were improved,leading to an improvement in learning and memory abilities(P＜0.05).Conclusion GDBSD can alleviate cognitive impairments in WD mice caused by pineal gland copper deposition by inhibiting oxidative stress and apoptosis in the pineal gland.The underlying molecular mechanism is associated with the regulation of the SIRT3/FOXO3α signaling pathway.

ObjectiveTo explore the possible mechanisms of Shoutai Wan （寿胎丸） in treating recurrent miscarriage （RSA） from the perspective of immune tolerance under the acidic microenvironment at the maternal-fetal interface. MethodsFemale CBA/J mice were randomly divided into normal group， model group， progesterone group， and Shoutai Wan group， with 15 mice in each group. The mice in the normal group and model group were given 0.2 ml distilled water by gavage each day， the Shoutai Wan group given Shoutai Wan decoction 0.15 g/（10 g·d） by gavage， the progesterone group given progesterone tablets 0.44 mg/（10 g·d） by gavage. After gavage for 14 days， the mice were cohabited. Female CBA/J mice in the normal group were mated with male BALB/c mice at a ratio of 2∶1， and female CBA/J mice in the other groups were mated with male DBA/2 mice at a ratio of 2∶1 to establish the RSA mouse model. Vaginal smears were taken from the female mice the next morning， and the appearance of a large number of spermatozoa and the presence of a vaginal plug were considered as the first day of pregnancy. After the appearance of the plug， the mice were continued to be administered according to the previous method until the 10th day of pregnancy. On the 10th day of pregnancy， maternal-fetal interface tissues were collected from each group of mice， and lactate dehydrogenase colorimetric method was used to detect lactate （LA） content； qPCR method and Western blot method were used to detect the expression of immune-related factors interleukin-4 （IL-4）， interferon-gamma （IFN-γ）， transforming growth factor beta 1 （TGF-β1）， and forkhead box protein 3 （Foxp3） mRNA and protein； flow cytometry was used to detect the numbers of helper T lymphocyte 1 （Th1）， helper T lymphocyte 2 （Th2）， regulatory T cell （Treg）， classical macrophage （M1）， and alternative macrophage （M2）. The bivariate Pearson test was used to analyze the correlation between LA content and the numbers of Th1， Th2， Treg， M1， and M2 cells， as well as the correlation between LA content and the expression of IL-4， IFN-γ， TGF-β1， Foxp3 protein， and mRNA. ResultsOn the 10th day of pregnancy， compared with the normal group， the LA content decreased in the model group， and the expression of IL-4， TGF-β1， Foxp3 protein and mRNA in the maternal-fetal interface tissues decreased， while the expression of IFN-γ protein and mRNA increased. The numbers of Th1 and M1 cells increased， while the numbers of Th2， Treg， and M2 cells decreased （P＜0.05 or P＜0.01）. Compared with the model group， the LA content increased in the Shoutai Wan group and progesterone group. The expression of IL-4， TGF-β1， Foxp3 protein and mRNA in the maternal-fetal interface tissues increased， while the expression of IFN-γ protein and mRNA decreased. The numbers of Th1 and M1 cells decreased， while the numbers of Th2， Treg， and M2 cells increased （P＜0.05 or P＜0.01）. The LA content was positively correlated with the numbers of Th2， Treg， and M2 cells， and the expression of IL-4， TGF-β1， Foxp3 protein， and mRNA （P＜0.05 or P＜0.01）； the LA content was negatively correlated with the numbers of Th1， M1 cells， and the expression of IFN-γ protein and mRNA （P＜0.05 or P＜0.01）. ConclusionShoutai Wan may improve immune tolerance by regulating the expression of immune-related factors in the acidic microenvironment at the maternal-fetal interface of RSA model mice， thereby exerting its role in preventing miscarriage.

Objective To observe the value of B1 corrected T1 mapping for distinguishing pathological types and differentiation degrees of lung cancers.Methods A total of 74 lesions in 65 patients with lung cancers were prospectively enrolled,including 49 poorly differentiated lesions and 25 moderately or well differentiated ones,i.e.42 adenocarcinomas,14 squamous cell carcinomas and 18 small cell lung cancers(all poorly differentiated).B1 corrected T1 mapping was performed,ROI(ROI1 and ROI2)were delineated using 2 methods,and T1 values of different pathological types and differentiation degrees lung cancers were compared.The receiver operating characteristic(ROC)curves were drawn,and the areas under the curve(AUC)were calculated.Results Significant differences of T1 values were found among different pathological types of lung cancer(all P＜0.05),as well as between small cell lung cancer and the rest 2 types of lung cancer(both P＜0.05).There were significant differences of T1 values between poorly differentiated and moderately well differentiated lung cancer(squamous cell carcinoma+adenocarcinoma)(both P＜0.05).Taken ROI1 T1 value=1 524.21 ms as the cut-off value,the AUC of T1 value for distinguishing poorly differentiated and moderately well differentiated lung cancer(squamous cell carcinoma+adenocarcinoma)was 0.698,with sensitivity of 64.50％and specificity of 76.00％.Taken ROI2 T1 value=1 630.68 ms as the cut-off value,the AUC of T1 value was 0.676,with sensitivity of 54.80％and specificity of 80.00％.Conclusion B1 corrected T1 mapping was helpful for distinguishing pathological types and differentiation degrees of lung cancers.

Objective To analyze the registered clinical trials of headache treated by TCM;To discuss the current research status;To provide reference for the optimization of subsequent clinical trial research plans.Methods All clinical trials of headache treated by TCM were retrieved from the ChiCTR and the ClinicalTrials.The retrieval time was from the database establishment to May 22,2023.The general characteristics,study types,intervention measures and outcome indicators of the trials were analyzed respectively.Results A total of 104 registered studies were included,with the number of registered studies increasing since 2004 and reaching a peak in 2020,involving 25 provincial administrative regions or countries and 69 clinical trial institutions;the funding sources were mainly scientific research funds of universities,national finance and local finance.The research type was mainly intervention research;the designing scheme was mainly randomized parallel control study;the high frequency random method was simple random method;45 registered studies used blind methods.Exploratory studies/pre-trials were the most commonly used in the phases of clinical researches.Most of the registered studies were single-center clinical trials with a total sample size of 9 648 patients.The main interventions were acupuncture and oral Chinese medicines.The high frequency outcome indicators included life quality of score,headache attack frequency,headache attack days and headache severity,etc.There were some problems in outcome indicators,such as non-standard,lack of TCM characteristic advantages,and insufficient patient participation.Conclusion The number of registered studies of headache treated by TCM has increased by year,but there are some problems in design elements,such as random method,blind method,number of research centers,sample size and the setting of outcome indicator.
