ObjectiveTo predict the mechanism through which Shasheng Maidong Tang enhances the efficacy of chemotherapy for lung cancer via network pharmacology and validate the prediction results in animal experiments. MethodsThe potential mechanism through which Shasheng Maidong Tang enhances the efficacy of chemotherapy for lung cancer was predicted by network pharmacology， liquid chromatography-mass spectrometry （LC-MS）， and molecular docking methods. C57/BL6 mice were assigned into normal， model， cisplatin， and Shasheng Maidong Tang+cisplatin groups. In addition to the normal group， the remaining groups were injected subcutaneously with 0.2 mL of 1×10⁷ cells·mL^-1 Lewis lung cancer cells to establish the Lewis lung cancer model. The daily gavage dose of Shasheng Maidong Tang was 3.58 g·kg^-1， and the concentration of cisplatin intraperitoneally injected on every other day was 2 mg·kg^-1. Drugs were administered for 14 d. The changes in the tumor volume and the rate of tumor suppression were monitored， and the tumor histopathological changes were observed by hematoxylin-eosin （HE） staining. Enzyme-linked immunosorbent assay was employed to measure the interleukin （IL）-6 and interferon （IFN）-γ levels in peripheral blood. Real-time PCR was performed to quantify the mRNA levels of Janus kinase 2 （JAK2）， signal transducer and activator of transcription 1 （STAT1）， and signal transducer and activator of transcription 3 （STAT3） in the tumor tissue of mice. Western blot was employed to determine the protein levels of JAK2， STAT3， B-cell lymphoma-2 （Bcl-2）， cysteinyl aspartate-specific proteinase-3 （Caspase-3）， and Pim-1 proto1 （PIM1） in the tumor tissue. Immunohistochemistry was employed to detect the expression of Bcl-2 and PIM1 in the tumor tissue. ResultsNetwork pharmacological predictions indicated that Shasheng Maidong Tang might enhance the efficacy of chemotherapy for lung cancer by regulating nitrogen metabolism， AGE-RAGE signaling pathway， cancer pathway， and JAK/STAT signaling pathway. The experimental results demonstrated that tumor volume in the cisplatin group and Shasheng Maidong Tang+cisplatin group was reduced compared with the model group， with statistically distinct differences observed on days 14， 17， 20 post modeling （P<0.05）. Notably， the Shasheng Maidong Tang+cisplatin therapy further decreased tumor volume compared with the cisplatin group， showing marked reductions on days 17 and 20 （P<0.05）， consistent with trends visualized in tumor volume comparison charts. The Shasheng Maidong Tang+cisplatin group exhibited higher tumor inhibition rate than the cisplatin group （P<0.05）. Histopathological analysis via HE staining revealed that the tumors in the model group displayed frequent nuclear mitosis， densely arranged cells， hyperchromatic nuclei， and no necrosis. Cisplatin treatment induced partial necrosis and vacuolization， while the Shasheng Maidong Tang+cisplatin group exhibited extensive necrotic regions， maximal vacuolization， disarranged tumor cells， and minimal mitotic activity. Compared with the model group， the cisplatin group and the Shasheng Maidong Tang+cisplatin group showed elevated level of IFN-γ （P<0.01） and declined level of IL-6 （P<0.01） in the peripheral blood. Compared with the cisplatin group， the Shasheng Maidong Tang+cisplatin group presented elevated level of IFN-γ （P<0.01） and lowered level of IL-6 （P<0.01） in the peripheral blood. Compared with the model group， the cisplatin group and the Shasheng Maidong Tang+cisplatin groups showed down-regulated mRNA levels of JAK2 and STAT3 （P<0.01） and up-regulated mRNA level STAT1 （P<0.01）. Compared with the cisplatin group， the Shasheng Maidong Tang+cisplatin group presented down-regulated mRNA levels of JAK2 and STAT3 （P<0.01） and up-regulated mRNA level of STAT1 （P<0.01）. Compared with the model group， the cisplatin group and the Shasheng Maidong Tang+cisplatin group showed down-regulated protein levels of JAK2 （P<0.01）， Bcl-2 （P<0.01）， PIM1 （P<0.01）， and STAT3 （P<0.05）， and up-regulated protein level of Caspase-3 （P<0.01）. Compared with the cisplatin group， Shasheng Maidong Tang+cisplatin group presented down-regulated protein levels of JAK2 （P<0.01）， Bcl-2 （P<0.01）， PIM1 （P<0.01）， STAT3 （P<0.05）， and up-regulated protein level of Caspase-3 （P<0.01）. The Bcl-2 and PIM1 expression results obtained by immunohistochemistry were consistent with those of Western blot. ConclusionShasheng Maidong Tang may enhance the efficacy of chemotherapy in the mouse model of Lewis lung cancer by regulating the JAK2/STAT3 signaling pathway.

The guidelines introduce, for the first time, the unified nomenclature of "Still′s disease" for both sJIA and AOSD, emphasizing the importance of early recognition and stepwise management. Particular attention is given to the role of IL-1 and IL-6 inhibitors in reducing glucocorticoid use. This article aims to assist clinicians in China in better understanding and applying these guidelines to enhance the diagnosis and treatment of Still′s disease.

Objective:To investigate the correlations of KCNJ5 gene mutations and pathological subtypes based on 11β-hydroxylase (CYP11B1)/aldosterone synthase (CYP11B2) immunohistochemistry with clinical characteristics and postoperative outcomes in patients with unilateral primary aldosteronism undergoing adrenalectomy.Methods:This retrospective study enrolled 155 patients with primary aldosteronism who underwent unilateral adrenalectomy at the Department of Hypertension, Ruijin Hospital, Shanghai Jiao Tong University School of Medicine, between May 2023 and May 2024. KCNJ5 mutations were detected by Sanger sequencing, and patients were stratified into KCNJ5-mutant and wild-type groups based on genetic results. The KCNJ5-mutant cohort was further subclassified into complete remission and partial remission groups according to surgical outcomes. For KCNJ5-mutant cases, postoperative tissues underwent immunohistochemical subtyping for CYP11B1/CYP11B2 expression, and were divided into the CYP11B2 mono-positive group (CYP11B1 -/CYP11B2 +) and the CYP11B1/CYP11B2 co-expression group (CYP11B1 +/CYP11B2 +). Correlations of KCNJ5 mutations and pathological subtypes with baseline characteristics, biochemical profiles, and postoperative outcomes in unilateral primary aldosteronism patients were analyzed. Results:A total of 100 patients were included in the final analysis, aged (51.1±11.0) years, including 35 females (35%). The somatic KCNJ5 mutation rate was 69% (69/100), with 69 KCNJ5-mutant and 31 wild-type cases. Compared to wild-type patients, KCNJ5-mutant patients were younger ((48.4±10.8) years vs. (56.9±9.3) years, P=0.000 2), had a higher female proportion (45% vs. 13%, P=0.004 0), exhibited lower preoperative renin levels (3.4 (1.1, 39.5) ng/L vs. 9.7 (2.7, 19.6) ng/L, P=0.009 1) and had a higher rate of complete clinical remission (55% vs. 16%, P=0.000 3). Among KCNJ5-mutant patients, 38 achieved complete remission and 31 achieved partial remission. The complete remission group demonstrated younger age ((45.6±10.2) years vs. (52.0±10.5) years, P=0.012 6), shorter hypertension duration ((6.2±6.1) years vs. (10.7±10.1) years, P=0.020 4), higher preoperative plasma (951.5 (652.2, 1 690.8) pmol/L vs. 749.8 (518.5, 955.4) pmol/L, P=0.027 7) and urinary ((86 271.4±51 873.8) pmol/24 h vs. (61 860.2±24 411.2) pmol/24 h, P=0.019 2) aldosterone levels, greater lateralization index (22.6 (10.1, 42.5) vs. 11.1 (5.1, 19.8), P=0.022 7), fewer baseline antihypertensive defined daily dose (2.6±1.3 vs. 4.0±1.3, P<0.000 1), and larger tumor diameter (1.5 (1.2, 1.8) cm vs. 1.1 (1.0, 1.5) cm, P=0.000 7). Immunohistochemical subtyping revealed CYP11B2 mono-positivity in 24 mutant cases and CYP11B1/CYP11B2 co-expression in 45. The CYP11B2 mono-positive group showed more pronounced postoperative reduction in antihypertensive defined daily dose (2.9±1.3 vs. 2.2±1.2, P=0.018 3), though no significant difference in complete remission rates (46% vs. 60%, P=0.259 8) was observed. Conclusion:In patients with unilateral primary aldosteronism, those carrying KCNJ5 somatic mutations exhibit characteristics such as younger age and a higher proportion of females compared to wild-type patients, along with significantly better surgical outcomes. Moreover, among patients with KCNJ5 mutations, those whose pathological subtype shows pure CYP11B2 expression demonstrate a more pronounced reduction in postoperative antihypertensive defined daily dose than those with co-expression of CYP11B1/CYP11B2.

Objective:To explore the association between pre-diabetes and glomerular hyperfiltration status in residents in China.Methods:The study subjects were the non-diabetes population in China Chronic Disease and Risk Factor Surveillance in 2018. According to the definition of prediabetes, the study subjects were divided into normoglycemic and pre-diabetes groups, and multivariate factorial logistic regression model was used to analyze the association between prediabetes and the risk for glomerular hyperfiltration and glomerular filtration rate decline, respectively. Restricted cubic spline was used to explore the dose-response relationship between different glycemic indexes and the risk for glomerular hyperfiltration.Results:A total of 129 735 eligible study subjects aged 18 to 74 years were included, including 45 336 persons with prediabetes. After adjusting for confounders, the OR for glomerular hyperfiltration in the prediabetes group was 1.26 (95% CI: 1.20-1.32) compared with the normoglycemic group, and prediabetes was not associated with decreased glomerular filtration rate ( OR=1.03, 95% CI: 0.96-1.12). Age-stratified results showed a 28% increase of risk for glomerular hyperfiltration in prediabetes group compared with normoglycemic group in those aged 18-59 year ( OR=1.28, 95% CI: 1.21-1.35), and a 15% increase of risk in old adults aged 60-74 years ( OR=1.15, 95% CI: 1.05-1.25); the risk for glomerular hyperfiltration in women with prediabetes ( OR=1.38, 95% CI: 1.29-1.47) was higher than that in men with prediabetes ( OR=1.14, 95% CI: 1.06-1.22); and the risk for prediabetes glomerular hyperfiltration was higher in those with insufficient physical activity ( OR=1.29, 95% CI: 1.22-1.36) than in those who were physically active ( OR=1.16, 95% CI: 1.04-1.29). Restricted cubic spline results showed that fasting plasma glucose, glycosylated hemoglobin and glomerular hyperfiltration risk all showed U-shaped associations, and 2 hours blood glucose glomerular hyperfiltration risk after taking sugar showed an approximate J-shaped association. Conclusions:The risk for glomerular hyperfiltration exists in the prediabetes population, and prediabetes is not associated with the decrease in glomerular filtration rate. Hyperglycemia control at an early and reversible stage is important to prevent glomerular hyperfiltration developing to hypofiltration and renal impairment.

Cervical spinal cord injury without fracture-dislocation (CSCIWFD) is referred to as a special type of cervical spinal cord injury characterized by traumatic spinal cord dysfunction and no significant bony structural abnormalities on imagines. Duo to the high risk of missed diagnosis during the initial consultation, CSCIWFD may lead to progressive neurological deterioration or even complete paralysis, severely impacting patients′ prognosis. Currently, there are no established consensuses over the diagnosis and treatment of CSCIWFD, such as the lack of evidence-based standards for indications of non-surgical treatment and risk of secondary neurological injury, as well as debates over the optimal timing for surgical intervention and indications for different surgical approaches. To address these issues, the Spine Trauma Group of the Orthopedic Branch of the Chinese Medical Doctor Association organized experts in the relevant fields to formulate Diagnosis and treatment guideline for acute cervical spinal cord injury without fracture- dislocation in adults ( version 2025) . Based on evidence-based medicine and the principles of scientific rigor and clinical applicability, the guidelines proposed 11 recommendations covering terminology, diagnosis, evaluation treatment, and rehabilitation, etc., aiming to standardize the management of CSCIWFD.

Objective:To evaluate the association between hypertension duration and risk for chronic kidney disease in residents in China.Methods:Participants aged 18-74 years from the sixth round of China Chronic Disease and Risk Factor Surveillance in 2018 were included. The age/date at hypertension diagnosis was reported by them, and hypertension duration was calculated based on the age at diagnosis and the age at survey. The hypertension duration was calculated as 0 year (i.e., normotensive participants), 0.1- year, 5.0- years, 10.0- years, and ≥15.0 years. Serum creatinine, urinary albumin, and urinary creatinine levels were measured, and chronic kidney disease was diagnosed when glomerular filtration rate was <60 ml·min -1·(1.73 m 2) -1 and/or urine albumin-to-creatinine ratio was ≥30 mg/g. Multivariable logistic regression analysis, which took intra-group correlation into account, was used to evaluate the association of hypertension duration with chronic kidney disease. Results:A total of 140 662 residents were finally included in the analysis. After adjusting the confounders, including blood pressure, the odds ratio of chronic kidney disease was 1.16 (95% CI: 1.09-1.23), 1.33 (95% CI: 1.20-1.48), 1.33 (95% CI: 1.18-1.49), and 1.43 (95% CI: 1.29-1.60) in study subjects with hypertension durations of 0.1-4.9 years, 5.0-9.9 years, 10.0-14.9 years, and ≥15.0 years, respectively, in comparison with normotensive people. This result was further supported by the positive association between hypertension duration and chronic kidney disease in people with previously diagnosed hypertension. The results of restricted cubic spline suggested that the risk for chronic kidney disease showed a steep increase within 0.1- 4.9 years after hypertension diagnosis, then showed neither increase nor decrease. The above association seemed to be stronger in those with hypertension diagnosed age <45 years. Compared with those with hypertension duration of 0.1-4.9 years, the odds ratio was 1.38 (95% CI: 1.04-1.84), 1.22 (95% CI: 0.91-1.65), and 1.47 (95% CI: 1.04-2.07) in those with hypertension durations of 5.0-9.9 years, 10.0-14.9 years, and ≥15.0 year, respectively. In those with hypertension diagnosis at ≥45 years, the corresponding odds ratio was 1.08 (95% CI: 0.98-1.19), 1.08 (95% CI: 0.97-1.21), and 1.16 (95% CI: 1.02-1.32), respectively. Conclusions:Hypertension duration is positively associated with the risk for chronic kidney disease in residents in China, and this association is independent of blood pressure level. Early diagnosis of hypertension and long-term control of blood pressure are effective strategies for secondary prevention of hypertension-related chronic kidney disease.

Objective:To understand the prevalence of chronic kidney disease (CKD) and influencing factors in adults with hypertension in China and provide evidence for the management of CKD in hypertension patients.Methods:The prevalence data of CKD in hypertension patients in China were collected from China Chronic Disease and Risk Factor Surveillance in 2018, the data of 68 829 hypertension patients were analyzed. After complex weighting, the prevalence of CKD in the study population was compared. A multivariate logistic regression model was used to explore the influencing factors of CKD in adults with hypertension.Results:The prevalence of CKD in the hypertension patients was 18.2% (95% CI: 17.4%-19.0%) and increased with age, and the prevalence was 16.4% in men and 20.6% in women ( P<0.001). In different age groups, CKD at stage G1 mainly occurred in those aged 18-44 and 45-59 years, with the prevalence of 10.8% and 7.8%, respectively, while CKD at stages G2 and G3a mainly occurred in those aged >60 years, with the prevalence of 9.4% and 9.7%. Multivariate logistic regression results showed that in the hypertension patients, being aged ≥60 years, being women, smoking (including current and ever smoking), physical inactivity, being underweight or obese, and suffering from diabetes, dyslipidemia and hyperuricemia were the potential risk factors for CKD (all P<0.05). Conclusion:The prevalence of CKD was higher in people with hypertension than in general population in China, and age, gender, smoking status, physical activity level, and suffering from diabetes, dyslipidemia, and hyperuricemia or not were significant influencing factors. It is necessary to strengthen health education and kidney function testing in adults with hypertension and develop comprehensive CKD prevention and control measures targeting high-risk population.

Objective:To compare the efficacy and safety of crisaborole ointment 2% versus pimecrolimus cream 1% in the treatment of mild to moderate atopic dermatitis in children aged 2 years or older.Methods:A multicenter, randomized, open-label, controlled clinical trial was conducted. A total of 120 pediatric patients aged 2 - 17 years with mild to moderate atopic dermatitis were enrolled from departments of dermatology of 8 hospitals in China between March 2022 and February 2023. The participants were randomly assigned in a 1∶1 ratio to the crisaborole group and the pimecrolimus group, and received the treatment with crisaborole ointment 2% and pimecrolimus cream 1% respectively, twice a day for 4 weeks. Visits were scheduled at baseline/on day 1, as well as on days 8, 15, and 29. The primary efficacy outcome was the percentage of patients achieving the Investigator's Static Global Assessment (ISGA) success (defined as clear [0] or almost clear [1] on the ISGA scale, combined with ≥ 2‐grade improvement from baseline) on day 29. The secondary efficacy outcomes included changes in the Eczema Area and Severity Index (EASI) total scores from baseline to day 29, percentages of patients achieving ISGA improvement (defined as clear [0] or almost clear [1] on the ISGA scale), as well as changes in the Peak Pruritus Numerical Rating Scale (NRS) scores, Dermatology Life Quality Index (DLQI) /Infants' Dermatology Life Quality Index (IDLQI) /Children's Dermatology Life Quality Index (CDLQI) scores, and in the Dermatitis Family Impact (DFI) scores. Drug safety was evaluated according to the incidence of adverse events. Categorical data were compared using the chi-square test. Since measurement data did not follow a normal distribution, the rank sum test was used for comparisons of measurement data between groups.Results:A total of 106 children with mild to moderate atopic dermatitis were included in the per-protocol analysis set, with 52 in the crisaborole group (26 males and 26 females) and 54 in the pimecrolimus group (27 males and 27 females). There were no significant differences in age, disease duration, ISGA and EASI scores at baseline between the two groups (all P > 0.05). On day 29, 22 patients (42.31%) in the crisaborole group and 25 (46.30%) in the pimecrolimus group achieved ISGA success, with no significant difference between the two groups ( χ2 = 0.17, P = 0.68) ; 35 patients (67.31%) in the crisaborole group and 45 (83.33%) in the pimecrolimus group achieved ISGA improvement, also with no significant difference between the two groups ( χ2 = 3.68, P = 0.06) ; additionally, there were no significant differences in the EASI, pruritus NRS, DLQI/IDLQI/CDLQI, or DFI scores between the two groups (all P > 0.05). Adverse reactions to the two topical agents were mainly local reactions such as mild to moderate pain, itching, or worsening of itching, and no obvious systemic adverse reactions occurred. The incidence of drug-related adverse reactions was 46.15% (24 cases) in the crisaborole group and 37.04% (20 cases) in the pimecrolimus group, with no significant difference between the two groups ( χ2 = 0.91, P = 0.34) . Conclusion:The efficacy of crisaborole ointment 2% was comparable to that of pimecrolimus cream 1% in the treatment of mild to moderate atopic dermatitis in children aged ≥ 2 years, and it yielded early and rapid improvement in the quality of life of patients and their families, with good safety and tolerability profiles.

Objective:To investigate the clinical efficacy of open arthrolysis in the treatment of posttraumatic elbow stiffness.Methods:A retrospective analysis was conducted on the data of 407 patients with post-traumatic elbow stiffness treated by open arthrolysis surgery in Shandong Provincial Hospital from January 2010 to January 2024. The cohort included 303 males and 104 females, with a mean age of 38.98±10.90 years (range, 18-72 years) and mean body mass index (BMI) of 24.32±3.29 kg/m 2 (range, 17.91-33.41 kg/m 2). There were 230 patients with right-sided elbow stiffness, 159 patients with left-sided elbow stiffness, and 18 patients with bilateral elbow stiffness. Initial injuries included 21 patients of isolated elbow dislocation; 25 patients of soft tissue injury; and 361 patients of initial intra-articular elbow fractures, among which there were 200 patients of multiple fractures, 87 patients of single distal humerus fracture, 43 patients of single proximal ulna fracture, and 31 patients of single radial head fracture. Initial injuries were treated non-surgically in 69 cases and surgically in 338 cases, among which 177 cases were retained with internal fixation. There were 334 preoperative patients complicated with heterotopic ossification and 73 patients without heterotopic ossification, with 99 patients undergoing early release (stiffness duration <6 months) and 308 patients undergoing late release (stiffness duration ≥6 months). Record the range of motion (ROM) of the elbow joint, forearm rotational range (FRR), visual analogue scale (VAS), Mayo elbow performance score (MEPS), modified Broberg-Morrey score (MBS), Oxford elbow score (OES), and disability of arm, shoulder and hand (DASH) score before and after surgery, and conduct comparative analysis. Results:All patients were followed up for an average of 41.86±10.27 months (range, 13-119 months). At 12 months postoperatively, elbow ROM improved from preoperative 33.7°±26.5° to 101.2°±24.0°, elbow FRR improved from preoperative 101.4°±53.5° to 138.9°±38.7°, the MEPS increased from 60.1±14.7 to 91.5±10.1, the BMS increased from 57.5±12.8 to 83.7±11.0, the OES decreased from 31.6±7.3 to 16.0± 4.6, the DASH score decreased from 38.8±13.9 to 10.1±9.5, and the VAS decreased from 3.0±2.3 to 0.9±1.1, with all changes showing statistical significance ( P<0.05). In patients with preoperative heterotopic ossification, postoperative mean flexion range was 120.1°±15.5° and elbow ROM was 102.6°±23.4°. In patients without preoperative heterotopic ossification, postoperative mean flexion range was 113.9°±15.6° and elbow ROM was 93.4°±26.4°. Statistically significant differences were observed between the two groups in postoperative flexion range and flexion-extension ROM. There were no statistically significant differences in the postoperative above-mentioned indicators between early and late release patients ( P>0.05). The supination range and elbow FRR in patients with multiple fractures were lower than those in patients with distal humerus fractures and proximal ulna fractures; the DASH score in patients with multiple fractures was higher than that in patients with proximal ulna fractures and radial head fractures; the OES score in patients with multiple fractures was higher than that in patients with proximal ulna fractures, and all differences were statistically significant ( P<0.05). Among 407 patients, complications included new-onset postoperative ulnar neuropathy in 61 cases, new heterotopic ossification in 11 cases, recurrent heterotopic ossification in 96 cases, elbow instability in 6 cases, and superficial surgical site infection in 2 cases. Conclusions:Open arthrolysis is an effective treatment option for post-traumatic elbow stiffness. Patients with preoperative heterotopic ossification have a greater postoperative flexion range and elbow flexion-extension range of motion. The surgical timing exerts no significant influence on the ultimate functional outcome of treatment in patients with post-traumatic elbow stiffness. Patients with different initial fracture sites exhibited significant differences in postoperative functional outcomes, including supination, DASH scores, and OES.

Objective:To investigate the infection rate of cytomegalovirus (CMV) and Epstein-Barr virus (EBV) in patients with severe aplastic anemia (SAA) after intensive immunosuppressive therapy in combination with a thrombopoietin receptor agonist (lST+TPO-RA) as well as assess the clinical impact of treatment.Methods:A retrospective, case series study was undertaken involving patients with SAA who were admitted to Soochow Hopes Hematonosis Hospital, The First Affiliated Hospital of Soochow University, and Zhengzhou Third People′s Hospital from June 2022 to February 2025. Thirty patients with complete CMV and EBV monitoring data after IST+TPO-RA treatment were enrolled. The first activation time of CMV and EBV, the maximum viral load, the first negative conversion time, and blood routine tests within 3 days before CMV and EBV positivity, during the positive period, and within 3 days after turning negative were recorded. The patients were followed up for 9 months after the completion of IST. One-way analysis of variance was used to compare the changes of blood routine before and after virus positivity and after turning negative. The χ2 test was used to compare the viral infection rate and the therapeutic effect of IST between the two groups. Results:The 30 SAA patients comprised 15 males and 15 females with an average age of (40.0±16.9) years. Of the 30 patients, 18 (60.0%) were infected with CMV and 6 (20.0%) with EBV. Among them, 17 cases received rabbit anti-human thymocyte immunoglobulin (r-ATG) treatment (r-ATG group), 13 cases received porcine anti-human lymphocyte immunoglobulin (p-ALG) treatment (p-ALG group). The CMV infection rate was significantly higher in the r-ATG group than in the p-ALG group (15/17 vs. 3/13, χ2=13.03, P<0.001); meanwhile, the rate of EBV infection was only slightly higher in the r-ATG group than in the p-ALG group, and the difference did not reach statistical significance (5/17 vs. 1/13, χ2=2.17, P=0.196). In patients infected with CMV, neutrophil, hemoglobin, and platelet counts were significantly decreased during the infection phase, followed by significant increases after CMV clearance ( F=14.48, 11.38, 4.73; all P<0.05). No significant differences in treatment efficacy were found between the r-ATG and p-ALG groups at 3, 6, and 9 months post-IST (all P>0.05). Conclusions:This preliminary study showed that the incidence of CMV and EBV infection in patients with SAA increased after IST, with CMV infections occurring significantly more frequently than EBV infections. The CMV infection rate was significantly higher in patients treated with r-ATG than in those receiving p-ALG. CMV infection was associated with notable alterations in hematological parameters, highlighting the need for close clinical monitoring.
