Acute lung injury(ALI) is a critical clinical condition primarily characterized by refractory hypoxemia and infiltration of inflammatory cells in lung tissue, which can progress into a more severe form known as acute respiratory distress syndrome(ARDS). Immune cells and inflammatory cytokines play important roles in the progression of the disease. Due to its unclear pathogenesis and the lack of effective clinical treatments, ALI is associated with a high mortality rate and severely affects patients' quality of life, making the search for effective therapeutic agents particularly urgent. Ginseng Radix et Rhizoma, the dried root of the perennial herb Panax ginseng from the Araliaceae family, contains active ingredients such as saponins and polysaccharides, which possess various pharmacological effects including anti-tumor activity, immune regulation, and metabolic modulation. In recent years, studies have shown that ginsenosides exhibit notable effects in reducing inflammation, ameliorating epithelial and endothelial cell injury, and providing anticoagulant action, indicating their comprehensive role in alleviating lung injury. This review summarizes the pathogenesis of ALI and the molecular mechanisms through which ginsenosides act at different stages of ALI development. The aim is to provide a scientific reference for the development of ginsenoside-based drugs targeting ALI, as well as a theoretical basis for the clinical application of Ginseng Radix et Rhizoma in the treatment of ALI.

OBJECTIVE: To investigate the molecular mechanism and explore blood transfusion strategies for a proband exhibiting the JK (a-b-) phenotype and anti-JK³ high frequency antigen antibody and her eight family members. METHODS: The Kidd blood phenotype and irregular antibodies in a family were identified by serologic tests. Exon 4-11 and intron region of SLC14A1 gene were sequenced by Sanger method. RESULTS: The combination of the gene JK*B (c.499A>G,c.512G>A,c.588A>G) and gene JK*B (c.342-1G>A,588A>G) in this family were considered to result in the JK (a-b-) phenotype in two members. The members carrying gene JK*A(c.130G>A,588A>G) all present serological JK^a+W. Members carrying gene JK*B (c.499A>G,c.588A>G) all present serological JK^b+W, which has not been previously reported to cause antigenic weakening. The proband with JK (a-b-) phenotype produced anti-JK³ antibodies, the hospital formulated a number of blood preparation strategies for the patient and she was discharged after recovery. CONCLUSION In this study, the molecular mechanism of JK (a-b-) in this family was identified, the transfusion strategy of rare blood group was established in our institution preliminary, and the necessity of establishing a rare blood group bank was revealed in this region. It is suggested that JK*B (c.499A>G,c.588A>G) may be a new genetic pattern leading to the weakening of Kidd antigenicity, which lays a foundation for the study of population genetics.

[Objective] To explore the cellular composition and gene expression characteristics of adrenocortical adenoma (ACA) based on single-nuclear RNA sequencing. [Methods] The postoperative resection samples of 2 ACA cases treated at our hospital during Jul.and Aug.2022 were collected.The cellular composition was isolated and identified with single-nuclear RNA sequencing, the adrenal cortical subgroups were subdivided with specific cortical cell subgroup markers, and the characteristic gene expression profile was studied. [Results] The main components of ACA were adrenal cortical cells (78.62%), endothelial cells (1.91%), fibroblasts (3.09%), macrophages (14.34%), and T cells (2.05%). Subdivision of cortical cells revealed a group of undefined cells (1.08%), in addition to zona glomerulosa (ZG) cells (1.77%), zona fasciculata (ZF) cells (94.98%), and zona reticularis (ZR) cells (2.17%). These undefined cells were characterized by high expression of intercellular adhesion molecule 1, growth arrest and DNA damage inducing proteins β, tumor necrosis factor α inducing protein 3 and CD36 molecules.According to correlation analysis of the gene expression, these undefined cells were similar to the ZF cells.DEGs enrichment analysis indicated that the metabolic process enrichment index was the highest in biological processes.Reactome GO enrichment analysis revealed that the immune system cytokine signaling response was the most significant.KEGG signaling pathway analysis showed that Th17 cell differentiation pathway was the mostly enriched.DEGs were found to be most closely related to viral infection by DO enrichment analysis. [Conclusion] This study reveals for the first time the gene expression profile characteristics of cell subset in ACA, which can provide reference to explore the mechanism of ACA.

Objective:To explore the influence of simultaneous integrated boost intensity-modulated radiation therapy (SIB-IMRT) on tumor markers and quality of life after breast-conserving surgery for breast cancer.Methods:Patients after breast-conserving surgery for breast cancer in the Third People' s Hospital of Chengdu were selected from June 2015 to June 2018 as the study subjects. Fifty-five cases with conventional radiotherapy (CRT) were selected and included in control group, and 49 cases with SIB-IMRT were enrolled as observation group. The radiotherapy time and radiotherapy-related adverse reactions, serum tumor markers (β2-microglobulin (β2-MG), carbohydrate antigen 125 (CA125), tissue polypeptide specific antigen (TPS), carbohydrate antigen 153 (CA153)) before radiotherapy and at 6 months after radiotherapy, short-term solid tumor treatment effect at 6 months after radiotherapy and quality of life (progression-free survival (PFS), overall survival (OS)) after 5 years of follow-up were collected in both groups of patients. Measurement data were presented as xˉ± s by t test. Enumeration data were analyzed by χ2 test or Fisher test. Nonparametric rank sum test was used to compare the distribution of ranked data between groups. Results:The radiotherapy time in observation group was shorter than that in control group ((37.46±6.74) d vs (43.63±7.26) d), and the incidence of radiotherapy-related adverse reactions was lower than that in control group (14.29% (7/49) vs 32.73% (18/55))(Statistical values were 4.47 and 4.83, P values were <0.001 and 0.028). At 6 months after radiotherapy, the levels of β2-MG, CA125, TPS and CA153 in observation group were lower compared to control group ((1.25±0.21) mg/L vs (1.86±0.37) mg/L, (15.17±2.56) kU/L vs (18.81±3.13) kU/L, (9.43±1.58) μg/L vs (13.49±2.51) μg/L, (11.75±1.63) kU/L vs (15.46±3.07) kU/L) ( t=10.17, 6.44, 9.73, 7.56; all P<0.01), but there was no statistical significance in disease control rate between the two groups ( P>0.05). The observation group had higher objective remission rate (53.06%(26/49) vs 32.73%(18/55)), and the difference was statistically significant( χ2=4.39, P=0.036). After a 5-year follow-up, 44 patients in the observation group survived (89.80%, 44/49), with an OS of (57.92±11.21) months; 42 patients in the control group survived (76.36%, 42/55), with an OS of (54.05±10.14) months. There was no statistically significant difference between the two groups (both P>0.05). The PFS of the observation group patients was higher than that of the control group ((54.93±10.07) months compared to (50.76±9.95) months), and the difference was statistically significant ( t=2.12, P=0.036). Conclusion:Simultaneous integrated boost intensity-modulated radiation therapy for breast cancer patients undergoing breast-conserving surgery can reduce the levels of serum tumor markers, improve the breast aesthetics, and enhance the short-term and long-term quality of life of patients.

Objective:To investigate the application value of single-sperm sequencing in resolving the carrier status of preim-plantation genetic testing(PGT)for chromosomal structural rearrangements in Robertsonian translocations.Methods:Haplotypes were constructed by single-sperm isolation combined with single-sperm sequencing for a patient with 45,XY,der(13;14)(q10;q10).Twenty single-sperm samples were isolated by mechanical braking and subjected to whole-genome amplification(WGA),and then the Asian Screening Array(ASA)gene chip was used to detect the 183 708 single nucleotide polymorphisms(SNP)of the WGA products.The single sperm associated with the translocation that could be used as haplotype inference was detected by copy number variation(CNV)sequencing,and the chromosomal haplotypes with normal and Robertsonian translocations were inferred.Three biopsy samples of embryonic trophoblast cells were used as the objects.After whole-genome amplification,high-throughput sequencing was employed to determine the status of the translocation chromosome carried by the embryos.The available blastocysts were selected for transfer,and the amniotic fluid samples were taken at 18 weeks of gestation to confirm whether the fetus carried the pathogenic muta-tion.Results:A total of 6 037 SNP sites were screened by single-sperm sequencing,and 30 sites selected to distinguish normal and translocation haplotypes.Preimplantation haplotype analysis showed that all the three embryos were euploids without Robertsonian translocation chromosome.Genetic testing of amniotic fluid in the second trimester confirmed that the karyotype of the fetus was 46,XN,carrying no Robertsonian translocation chromosome.Conclusion:For male carriers of Robertsonian translocation,single sperm sequencing can be used to screen SNP sites to construct haplotypes for distinguishing normal and Robertsonian translocation em-bryos,and to provide a basis for embryo selection by preimplantation chromosomal structural genetic testing.

Objective:To explore the prevalence and independent associated factors of vascular calcification (VC) in non-dialysis chronic kidney disease (CKD) patients of stage 3-5.Methods:It was a single-center cross-sectional observational study. Non-dialysis stage 3-5 CKD patients ≥18 years old who were admitted to the Department of Nephrology, the First Affiliated Hospital of Sun Yat-sen University from May 1, 2022 to December 31, 2022 with VC evaluation were enrolled. The patients' general information, laboratory examination and imaging data were collected. Coronary artery calcification (CAC), thoracic aorta calcification (TAC), abdominal aorta calcification (AAC), carotid artery calcification and aortic valve calcification (AVC) were evaluated by cardiac-gated electron-beam CT (EBCT) scans, lateral lumbar x-ray, cervical macrovascular ultrasound and echocardiography, respectively. The differences in clinical data and the prevalence of VC at different sites of patients with different CKD stages were compared, and the prevalence of VC at different sites of patients in different age groups [youth group (18-44 years old), middle-aged group (45-64 years old) and elderly group (≥65 years old)] and patients with or without diabetes were compared. Multivariate logistic regression analysis was used to analyse the independent associated factors of VC for different areas.Results:A total of 206 patients aged (51±14) years were included, including 129 (62.6%) males. There were 44 patients with CKD stage 3 (21.4%), 51 patients with CKD stage 4 (24.8%), and 111 patients with CKD stage 5 (53.9%). CKD was caused by chronic glomerulonephritis [104 cases (50.5%)], diabetic kidney damage [35 cases (17.0%)], hypertensive kidney damage [29 cases (14.1%)] and others [38 cases (18.4%)]. Among 206 patients, 131 (63.6%) exhibited cardiovascular calcification, and the prevalence of CAC, TAC, AAC, carotid artery calcification, and AVC was 37.9%, 43.7%, 37.9%, 35.9% and 9.7%, respectively. The overall prevalence of VC in young, middle-aged and elderly patients was 24.6%, 73.6% and 97.4%, respectively. With the increase of age, the prevalence of VC in each site gradually increased, and the increasing trend was statistically significant (all P<0.001). The overall prevalence of VC in CKD patients with diabetes was 92.5% (62/67), and the prevalence of VC at each site in the patients with diabetes was significantly higher than that in the patients without diabetes (all P<0.001). Multivariate logistic regression analysis revealed that age (every 10 years increase, OR=2.51, 95% CI 1.77-3.56, P<0.001), hypertension ( OR=5.88, 95% CI 1.57-22.10, P=0.009), and diabetes ( OR=4.66, 95% CI 2.10-10.35, P<0.001) were independently correlated with CAC; Age (every 10 years increase, OR=6.43, 95% CI 3.64-11.36, P<0.001) and hypertension ( OR=6.09, 95% CI 1.33-27.84, P=0.020) were independently correlated with TAC; Female ( OR=0.23, 95% CI 0.07-0.72, P=0.011), age (every 10 years increase, OR=3.90, 95% CI 2.42-6.29, P<0.001), diabetes ( OR=5.37, 95% CI 2.19-13.19, P<0.001) and serum magnesium ( OR=0.01,95% CI 0-0.35, P=0.014) were independently correlated with AAC. Moreover, age and diabetes were independently correlated with carotid artery calcification, AVC and overall VC Conclusions:The prevalence of VC in non-dialysis CKD patients of stage 3-5 is 63.59%, of which CAC reaches 37.9%, TAC is the most common one (43.7%), while AVC is the least one (9.7%). Age and diabetes are the independent associated factors for VC of all sites except TAC, while hypertension is an independent associated factor for both CAC and TAC.

Through consulting the ancient herbs， medical books and modern literature， this paper made textual research on the name， origin， producing area， quality evaluation， collection and processing of medicinal materials of Sang （Mori Folium， Mori Cortex， Mori Ramulus， Mori Fructus） in famous classical formulas， in order to provide a basis for the development of famous classical formulas containing medicinal materials of Sang. According to the research， Mori Folium and Mori Cortex were first used as medicines in Shengnong Bencaojing ， Mori Ramulus was first used as medicine in Jinxiaofang， and Mori Fructus was first used as medicine in Xinxiu Bencao. Before the Tang dynasty， there were Nyusang and Shansang. Since Tang dynasty， there were many sources of medicinal materials of Sang， including Baisang （Morus alba）， Jisang （M. australis）， Shansang （M. mongolica）， etc. According to textual research， the mainstream varieties were M. australis， M. alba and their cultivated varieties. In modern times， according to the relevant information and the Chinese Pharmacopoeia， M. alba is the original base. In ancient times， the origin of mulberry changed with the development of sericulture， mulberry has been widely planted since the Song dynasty. In the Ming and Qing dynasties， mulberry has been planted most in Jiangsu and Zhejiang. In modern times， they are mainly produced in Jiangsu， Zhejiang， Anhui， Hunan and other places. In recent years， due to the related policies and strategies such as "moving silkworms from east to west"， the center of silkworm breeding has gradually transferred to the west. As for the quality evaluation and harvesting and processing of mulberry medicinal materials， Most of the ancient and modern records of Mori Folium are the same. They are harvested after frost， and dried after removing impurities. The quality is better when the leaves are large and thick， yellowish green， holding prickly hands and undergoing frost. The harvesting period of Mori Cortex is slightly different in ancient and modern records. Ancient books record that it can be harvested all the year round， but in modern times， it is mostly harvested from late autumn to the next spring. The processing methods include removing soil and fibrous roots， scraping off yellow-brown rough skin， peeling off white skin and drying in the sun. The quality is better when they are white， thick， flexible， free of rough skin and full of powder. There are few records about the collection， processing and quality evaluation of Mori Ramulus and Mori Fructus in ancient Chinese herbal books. According to modern literature， Mori Ramulus is usually collected in late spring and early summer， with leaves removed， slightly dried， sliced while fresh， and dried in the sun. The best quality of Mori Ramulus is fine and tender with the yellow and white section. Mori Fructus is harvested from April to June when the fruit turns red， and dried in the sun， or slightly steamed and dried in the sun， and it is better to be big， dark purple， oily and thick. There are many processing methods of mulberry medicinal materials. Ancient books record stir frying， baking， burning and steaming of Mori Folium， in modern times， there is honey-roasted method， but most of them are used as raw products. In ancient materia medica， Mori Cortex has firing method， baking method， stir-frying method， honey-fried method， etc. In modern times， there are stir-fried and honey-fried methods， and most of them are used as raw products. Ancient books record that Mori Ramulus has cutting and frying methods， while modern ones have cutting， frying， wine-processed and bran-processed methods. Processing methods of Mori Fructus are consistent in ancient and modern times， and they are mostly dried after being cleaned or steamed. Based on the research results， it is suggested that M. alba should be selected as mulberry medicinal materials in the famous classical formulas， and appropriate medicinal parts and processing methods can be selected according to the indications of the famous classical formulas.

By referring to the relevant ancient herbal literature， medical records and prescription books， the textual research of Violae Herba has been conducted to verify the name， origin， producing area， quality evaluation and processing method changes. The results showed that the name of Zihua Diding originated from its flower color and plant morphological characteristics. The primitive plant of Violae Herba is Viola genus of Violaceae， V. yedoensis， as stipulated in the 2020 edition of Chinese Pharmacopoeia， has been the mainstream in past dynasties of China. Violae Herba is mainly wild， and it is widely distributed throughout the country. Since modern times， the quality of Violae Herba is better with integrity， green color and yellow root. There are few records on the harvesting and processing methods of Violae Herba in ancient times， most of which are directly used after drying. It is suggested that the collection and processing methods of Violae Herba in the famous classical formulas can be implemented in accordance with the provisions of the 2020 edition of Chinese Pharmacopoeia.
