ObjectiveTo explore the dose-effect relationship and safety of high， medium， and low doses of raw Astragali Radix in the modified Huangqi Chifengtang （MHCD） for treating proteinuria in immunoglobulin A （IgA） nephropathy， and to provide scientific evidence for the clinical use of high-dose Astragali Radix in the treatment of proteinuria in IgA nephropathy. MethodsA total of 120 patients with IgA nephropathy， diagnosed with Qi deficiency and blood stasis combined with wind pathogen and heat toxicity， were randomly divided into a control group and three treatment groups. The control group received telmisartan combined with a Chinese medicine placebo， while the treatment groups were given telmisartan combined with MHCD containing different doses of raw Astragali Radix （60， 30， 15 g）. Each group contained 30 patients， and the treatment period was 12 weeks. Changes in 24-hour urinary protein （24 hUTP）， traditional Chinese medicine （TCM） syndrome scores， effective rate， and renal function were observed before and after treatment. Safety was assessed by monitoring liver function and blood routine. ResultsAfter 12 weeks of treatment， 24 hUTP significantly decreased in the high， medium， and low-dose groups， as well as the control group （P<0.05， P<0.01）. The TCM syndrome scores in the high， medium， and low-dose groups also significantly decreased （P<0.01）. Comparisons between groups showed that the 24 hUTP in the high-dose group was significantly lower than in the medium， low-dose， and control groups （P<0.05， P<0.01）， and the 24 hUTP in the medium-dose group was significantly lower than in the control group （P<0.05）. The TCM syndrome scores in the high and medium-dose groups were significantly lower than in the low-dose and control groups （P<0.05， P<0.01）. The total effective rates for proteinuria in the high， medium， low-dose， and control groups were 92.59% （25/27）， 85.19% （23/27）， 60.71% （17/28）， and 57.14% （16/28）， respectively. The effective rates in the high and medium-dose groups were significantly higher than in the low-dose and control groups （χ²=13.185， P<0.05， P<0.01）. The effective rates for TCM syndrome scores in the high， medium， low-dose， and control groups were 88.89% （24/27）， 81.48% （22/27）， 71.43% （20/28）， and 46.43% （13/28）， respectively. The efficacy of TCM syndrome scores in the high and medium-dose groups was significantly higher than in the control group （χ²=14.053， P<0.01）. Compared with pre-treatment values， there was no statistically significant difference in eGFR and serum creatinine in the high and medium-dose groups. However， eGFR significantly decreased in the low-dose and control groups after treatment （P<0.05）， and serum creatinine levels increased significantly in the control group （P<0.05）. No statistically significant differences were observed in urea nitrogen， uric acid， albumin， total cholesterol， triglycerides， liver function， and blood routine before and after treatment in any group. ConclusionThere is a dose-effect relationship in the treatment of IgA nephropathy with high， medium， and low doses of raw Astragali Radix in MHCD. The high-dose group exhibited the best therapeutic effect and good safety profile.

Objective:To explore the association between different feeding methods during the first six months after birth and the physical growth of children aged 3 to 5 years.Methods:Data were from the "Taicang and Wuqiang mother-child cohort study"(TAWS) in China. Children were enrolled at birth between November 2016 and September 2020 and followed up at 1, 2, 3, 6, 8, 12, 18, and 24 months, as well as at ages 3 to 5 years. Based on feeding methods within six months of age, children were categorized into an "exclusive breastfeeding group" and a "formula-feeding group". Birth-related information and feeding practices between 8 and 24 months were collected, alongside dietary habits, physical activity, and illness during preschool years. Height and weight of preschool children were measured to calculate height-for-age Z-score (HAZ), weight-for-age Z-score (WAZ), body mass index-for-age Z-score (BAZ), and the rates of stunting, underweight, wasting, overweight, and obesity. After adjusting for demographic factors, birth-related information, feeding practices between 8 to 24 months, preschool dietary habits, physical activity, and health status, multiple linear regression and logistic regression were adopted to analyze the influence of feeding methods within six months of age on the physical growth of children aged 3 to 5 years.Results:A total of 1 233 children were included, comprising 629 boys and 604 girls. The number of children aged 3, 4, and 5 years was 436, 406, and 391, respectively. About 754 children were categorized into the exclusive breastfeeding group and 479 into the formula-feeding group. Children who were introduced to formula milk within six months of age had higher HAZ (0.09±0.99), WAZ (0.24±1.07) and BAZ (0.26±1.11) scores at ages 3 to 5 compared to the exclusive breastfeeding group [HAZ, WAZ, and BAZ were (-0.04±0.92), (0.06±1.02) and (0.11±1.08), respectively]. After adjusting for confounding factors, multiple linear regression analysis showed that the β (95% CI) values for HAZ, WAZ and BAZ in the formula-feeding group were 0.16 (0.06-0.25), 0.17 (0.06-0.29) and 0.15 (0.02-0.27), respectively, compared to the exclusive breastfeeding group. After adjusting for confounding factors, the results of the multivariate logistic regression model indicated that there were no statistically significant differences in the risks of stunting, underweight, wasting, overweight, and obesity during the preschool years between the exclusive breastfeeding group and the formula-feeding group, with OR (95% CI) values of 1.04 (0.41-2.62), 0.99 (0.27-3.57), 1.63 (0.53-4.95), 1.08 (0.66-1.74), and 1.58 (0.70-3.60), respectively. Conclusion:Exclusive breastfeeding within six months of age does not increase the risk of undernutrition (including stunting, underweight or wasting) during preschool years. However, the introduction of formula feeding within six months of age significantly increases the physical growth level of the preschool stage.

Objective:To compare the clinical efficacy and safety of bronchial artery chemoembolization (BACE) combined with anlotinib (BACE+A) versus BACE alone in patients with stage III-IV non-small cell lung cancer (NSCLC).Methods:A total of 94 patients with advanced NSCLC treated at six interventional centers between November 2020 and November 2021 were retrospectively enrolled. Patients were divided into the BACE+A group ( n=46) and the BACE alone group ( n=48) based on treatment regimen. Baseline and perioperative clinical data were collected and compared between the two groups. Treatment response was evaluated using the modified Response Evaluation Criteria in Solid Tumors (mRECIST) at 1, 6, and 12 months after the first BACE procedure. Objective response rate (ORR), disease control rate (DCR), progression-free survival (PFS), overall survival (OS), and treatment-related adverse events (AEs) were recorded. Kaplan-Meier survival curves were plotted to compare median OS and PFS between groups. Cox proportional hazards regression analysis was used to identify factors influencing OS and PFS. Results:The Kaplan-Meier analysis showed that the median OS was significantly longer in the BACE+A group (18.8 months, 95% CI 16.3-21.3) than in the BACE group (13.4 months, 95% CI 11.6-15.2) ( P=0.001). The median PFS was also significantly longer in the BACE+A group (9.0 months, 95% CI 7.3-10.7) compared to the BACE group (6.1 months, 95% CI 4.9-7.3) ( P=0.001). At 6 and 12 months post-first BACE, the ORR (43.5%, 40.0%) and DCR (89.1%, 83.3%) were significantly higher in the BACE+A group than in the BACE group (ORR: 20.8%, 14.8%; DCR: 66.7%, 59.3%) (all P<0.05). Multivariate Cox regression identified treatment with BACE+A ( HR=0.42, 95% CI 0.27-0.72, P=0.002), tumor stage ( HR=1.80, 95% CI 1.05-3.07, P=0.031), presence of pre-existing complications requiring intervention ( HR=2.72, 95% CI 1.65-4.50, P<0.001), and >2 BACE procedures ( HR=0.32, 95% CI 0.15-0.68, P=0.003) as independent factors influencing OS. Treatment with BACE+A ( HR=0.49, 95% CI 0.32-0.76, P=0.001), tumor stage ( HR=1.72, 95% CI 1.07-2.77, P=0.025), multi-arterial tumor blood supply ( HR=2.76, 95% CI 1.76-4.31, P<0.001), and>2 BACE procedures ( HR=0.40, 95% CI 0.22-0.71, P=0.002) were independent factors influencing PFS. There was no significant difference in BACE-related adverse events between the two groups (all P>0.05). Hypertension, fatigue, hand-foot syndrome, and anorexia were common anlotinib-specific adverse reactions in the combination group, but no grade 4 or higher adverse reactions were observed. Conclusions:BACE combined with anlotinib demonstrates superior efficacy compared to BACE alone in treating advanced NSCLC, significantly prolonging OS and PFS. The safety profile is manageable, with adverse events remaining within tolerable limits.

Ulcerative colitis （UC）， a chronic， non-specific inflammatory bowel disease with typical symptoms such as abdominal pain， diarrhea， and bloody stools， demonstrates a high relapse rate and difficulty in curing. Sishenwan， first recorded in Internal Medicine Abstract （Nei Ke Zhai Yao）， are a classic prescription for treating diarrhea caused by deficiency of the spleen and kidney Yang. The core therapeutic principle of Sishenwan is warming and tonifying the spleen and kidney， and astringing the intestine and stopping diarrhea. In recent years， Sishenwan have demonstrated distinct advantages in the clinical treatment of UC. The pathogenesis of UC involves multiple factors， including immune dysregulation and gut microbiota imbalance. Although Western medicine is effective in the short term， its side effects， high relapse rate， and resistance associated with long-term use pose substantial challenges. Sishenwan have shown excellent clinical outcomes in the treatment of UC due to deficiency of the spleen and kidney Yang. Modern clinical studies indicate that Sishenwan， used alone or in combination with Western medicine or other Chinese medicine compound prescriptions， significantly improve the clinical efficacy in treating UC due to deficiency of the spleen and kidney Yang. Sishenwan effectively alleviate core symptoms such as mucus， pus， and blood in stools， and persistent abdominal pain， reduce Mayo scores and the relapse rate， and improve patients' quality of life. Research on the material basis reveals that Sishenwan contain multiple active ingredients such as psoralen， isopsoralen， and evodiamine. Mechanism studies indicate that Sishenwan inhibit the inflammatory cascade reactions by regulating the signal network through multiple targets. Sishenwan regulate cellular immunity and restore intestinal immune homeostasis. At the microecological level， Sishenwan promote the intestinal barrier repair through the "microbiota-metabolism-immunity" axis. The current research still needs to be deepened in aspects such as the mining of specific biomarkers for syndromes and the exploration of the collaborative mechanism of traditional Chinese and Western medicine. In the future， a full-chain system covering syndrome differentiation， targeting， and monitoring needs to be constructed for promoting the paradigm transformation of Sishenwan into precision drugs. This review systematically explains the treatment mechanism of Sishenwan regarding the combination of disease and syndrome and its multi-target regulatory characteristics， providing a theoretical basis and transformation direction for the treatment of UC with integrated traditional Chinese and Western medicine.

This study explored the effect of the Mycobacterium tuberculosis(Mtb)PE/PPE family protein PE_PGRS37 on the growth of Mycobacterium smegmatis(Ms)and macrophage autophagy during Mtb infection.The pe_pgrs37 gene was amplified from Mtb genome through PCR,and the recombinant vector pAIN-PE_PGRS37 was successfully constructed through homologous recombi-nation.pAIN-PE_PGRS37 and pAIN were integrated into Ms through electroshock to construct pAIN-PGRS37/Ms and pAIN/Ms re-combinant bacteria.Western blotting indicated that the PE_PGRS37 protein was correctly expressed in pAIN-PE_PGRS37/Ms.The re-combinant bacteria were inoculated in 7H9/7H10 medium,and their colony morphology and growth curves were observed.No signifi-cant difference in colony morphology was observed between pAIN-PE_PGRS37/Ms and pAIN/Ms.The growth rate significantly in-creased between 10 and 16 h,and a plateau was reached at 26 h.After infection of U937 cells with pAIN-PE_PGRS37/Ms and pAIN/Ms,macrophage autophagy flow was detected with western blotting and immunofluorescence.In the pAIN-PE_PGRS37/Ms-infected group,compared with the pAIN/Ms-infected group,macrophage LC3-II and p62 protein expression was significantly up-regulated(P<0.001)and inhibited autophagosome and lysosome fusion.The intracellular survival of the recombinant bacteria was detected through colony counting,and pAIN-PE_PGRS37/Ms showed significantly greater survival in macrophages at 12 h,24 h,and 48 h than pAIN/Ms(P<0.05).Our results suggested that PE_PGRS37 protein promotes Mycobacterium survival in macrophages by blocking macro-phage autophagy flow,thus inhibiting macrophage autophagy.

Conclusion:Exclusive breastfeeding within six months of age does not increase the risk of undernutrition (including stunting, underweight or wasting) during preschool years. However, the introduction of formula feeding within six months of age significantly increases the physical growth level of the preschool stage.

Myeloid neoplasms (MNs) belong to a group of hematological malignancies characterized by the abnormal biological functions of hematopoietic stem progenitor cells. The abnormal immune and hematopoietic microenvironment of patients with MN interact with malignant clonal hematopoietic stem cells, promoting the occurrence and development of their diseases. MN large granular lymphocyte proliferation (MN-LGLP) is a special and rare clinical phenomenon in this type of disease. Currently, research on this disease in domestic and international cohorts is limited. This study analyzes the clinical and laboratory characteristics of this type of patient and explores the impact of LGLP on the clinical characteristics and survival of patients with MN. Patients with MN-LGLP are prone to neutropenia and splenomegaly. The presence of LGLP is not a risk factor affecting the survival of patients with MN-LGLP. STAG, ASXL1, and TET2 are the most common accompanying gene mutations in MN-LGLP, and patients with MN-LGLP and STAG2 mutations have poor prognoses.
