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 genetic basis of RhD-negative phenotype in the blood donor population of Nantong City. Methods: RHD genotyping was performed on 386 randomly selected RhD-negative donor samples (from a total of 676 RhD-negative donors identified between January 20, 2023, and June 28, 2024) using polymerase chain reaction (PCR), and the inconclusive results were confirmed by nucleotide sequencing. Results: Ten RHD allele types were identified: The complete deletion variant RHD 01N.01 was predominant (64.25%, 248/386); followed by RHD 01EL.01 (19.69%, 76/386). RHD 01N.03, RHD 01N.04, RHD 01N.16 and RHD 01EL.32 were frequently observed., RHD 01EL.02, RHD 01EL.08, RHD 01EL.37 and RHD 01N.25 were rare, and two exon deletion variants remained uncharacterized. The phenotypic distribution of RhD-negative blood donors was ccee (55.44%)>Ccee(31.09%)>ccEe(5.96%)>CCee(5.44%)>CcEe(1.81%)>CcEE(0.26%), and the antigen distribution trend was e(99.74%)>c(94.56%)>C(38.60%)>E(8.03%). A correlation was observed between RHD genotypes and RhCE phenotypes. Conclusion: The Nantong blood donor population exhibits unique RHD gene polymorphisms. Integrating RhCE serological phenotyping with RHD genotyping is essential for ensuring transfusion safety.

OBJECTIVE: To investigate the clinical efficacy of lengthened proximal femoral nail antirotation (PFNA) and InterTan in the treatment of subtrochanteric femur fractures in the elderly. METHODS: A retrospective analysis was performed on the data of 65 elderly patients diagnosed with subtrochanteric femoral fractures who met the inclusion criteria between October 2016 and January 2022. The enrolled patients were categorized into two groups according to the type of internal fixation used: the lengthened proximal femoral nail antirotation(PFNA) group and the InterTan group. There were 32 patients in the PFNA group, comprising 20 males and 12 females, with ages ranging from 60 to 85 years old with an average of (69.3±6.7 ) years old. Among these patients, 15 patients resulted from traffic accidents and 17 patients were caused by falls. According to the Seinsheimer classification system, there were 11 patients as type Ⅱ, 14 patients as type Ⅲ, 6 patients as type Ⅳ, and 1 patient as type Ⅴ. The InterTan group comprised 33 patients, including 20 males and 13 females, aged from 60 to 85 years old with an average of (69.8±7.8 ) years old. Of these, 15 patients resulted from traffic accidents, while 18 patients were caused by falls. According to the Seinsheimer classification system, 10 patients as type Ⅱ, 15 patients as type Ⅲ, 7 patients as type Ⅳ, and 1 patient as type Ⅴ. The intraoperative blood loss, operative duration, and fracture healing time were recorded and compared between two groups. The quality of fracture reduction was assessed using Chang's criteria. Additionally, the Harris hip score was utilized to evaluate hip function in both groups at 3 months postoperatively and at the final follow-up. RESULTS: All patients were followed up for a period ranging from 10 to 20 months with an average of (14.6±4.5) months. No statistically significant differences were observed between two groups in terms of operation time, intraoperative blood loss, quality of fracture reduction, or reduction methods (P>0.05). Three months after the surgery, the Harris hip score in the InterTan group was 80.0(78.0, 83.5) points, which was significantly higher than that in the PFNA group, which recorded a score of 77.5(75.0, 81.8) points. This difference was statistically significant (P<0.05). At the final follow-up, the Harris hip score in the InterTan group was 80.0(76.5, 87.0), while that in the PFNA group was 78.0(74.3, 82.8). No statistically significant difference was observed between two groups (P>0.05). CONCLUSION The use of lengthened PFNA and InterTan in the treatment of elderly subtrochanteric femur fractures can both achieve good treatment results, with the advantages of simple operation, firm fixation, and low failure rate of internal fixation. The lengthened InterTan can achieve better hip function than PFNA.

Testicular histology based on testicular biopsy is an important factor for determining appropriate testicular sperm extraction surgery and predicting sperm retrieval outcomes in patients with azoospermia. Therefore, we developed a deep learning (DL) model to establish the associations between testicular grayscale ultrasound images and testicular histology. We retrospectively included two-dimensional testicular grayscale ultrasound from patients with azoospermia (353 men with 4357 images between July 2017 and December 2021 in The First Affiliated Hospital of Sun Yat-sen University, Guangzhou, China) to develop a DL model. We obtained testicular histology during conventional testicular sperm extraction. Our DL model was trained based on ultrasound images or fusion data (ultrasound images fused with the corresponding testicular volume) to distinguish spermatozoa presence in pathology (SPP) and spermatozoa absence in pathology (SAP) and to classify maturation arrest (MA) and Sertoli cell-only syndrome (SCOS) in patients with SAP. Areas under the receiver operating characteristic curve (AUCs), accuracy, sensitivity, and specificity were used to analyze model performance. DL based on images achieved an AUC of 0.922 (95% confidence interval [CI]: 0.908-0.935), a sensitivity of 80.9%, a specificity of 84.6%, and an accuracy of 83.5% in predicting SPP (including normal spermatogenesis and hypospermatogenesis) and SAP (including MA and SCOS). In the identification of SCOS and MA, DL on fusion data yielded better diagnostic performance with an AUC of 0.979 (95% CI: 0.969-0.989), a sensitivity of 89.7%, a specificity of 97.1%, and an accuracy of 92.1%. Our study provides a noninvasive method to predict testicular histology for patients with azoospermia, which would avoid unnecessary testicular biopsy.

BACKGROUND: Blood glucose and serum albumin have been associated with cardiovascular disease prognosis, but the impact of admission-blood-glucose-to-albumin ratio (AAR) on adverse outcomes in critical ill coronary artery disease (CAD) patients was not investigated. METHODS: Patients diagnosed with CAD were non-consecutively selected from the MIMIC-IV database and categorized into quartiles based on their AAR. The primary outcome was 1-year mortality, and secondary endpoints were in-hospital mortality, acute kidney injury (AKI), and renal replacement therapy (RRT). A restricted cubic splines model and Cox proportional hazard models assessed the association between AAR and adverse outcomes in CAD patients. Kaplan-Meier survival analysis determined differences in endpoints across subgroups. RESULTS: A total of 8360 patients were included. There were 726 patients (8.7%) died in the hospital and 1944 patients (23%) died at 1 year. The incidence of AKI and RRT was 63% and 4.3%, respectively. High AAR was markedly associated with in-hospital mortality (HR = 1.587, P = 0.003), 1-year mortality (HR = 1.502, P < 0.001), AKI incidence (HR = 1.579, P < 0.001), and RRT (HR = 1.640, P < 0.016) in CAD patients in the completely adjusted Cox proportional hazard model. Kaplan-Meier survival analysis noted substantial differences in all endpoints based on AAR quartiles. Stratified analysis and interaction test demonstrated stable correlations between AAR and outcomes. CONCLUSIONS The results highlight that AAR may be a potential indicator for assessing in-hospital mortality, 1-year mortality, and adverse renal prognosis in critical CAD patients.

The disturbance of the human microbiota influences the occurrence and progression of many diseases. Live therapeutic bacteria, with their genetic manipulability, anaerobic tendencies, and immunomodulatory properties, are emerging as promising therapeutic agents. However, their clinical applications face challenges in maintaining activity and achieving precise spatiotemporal release, particularly in the harsh gastrointestinal environment. This review highlights the innovative bacterial functionalized encapsulation strategies developed through advances in physicochemical and biological techniques. We comprehensively review how bacterial encapsulation strategies can be used to provide physical barriers and enhanced adhesion properties to live microorganisms, while introducing superior material properties to live bacteria. In addition, this review outlines how bacterial surface coating can facilitate targeted delivery and precise spatiotemporal release of live bacteria. Furthermore, it elucidates their potential applications for treating different diseases, along with critical perspectives on challenges in clinical translation. This review comprehensively analyzes the connection between functionalized bacterial encapsulation and innovative biomedical applications, providing a theoretical reference for the development of next-generation bacterial therapies.

Objective:To investigate the clinicopathological features, immunophenotype and molecule characteristics of EWSR1::CREM fusion malignant epithelioid neoplasm in soft tissue.Methods:The clinical and pathological data of 2 cases of EWSR1::CREM fusion malignant epithelioid neoplasm in soft tissue diagnosed at the Department of Pathology, Beijing Jishuitan Hospital, Beijing, China from May 2023 to May 2024 were analyzed. Immunohistochemical study, fluorescence in situ hybridization (FISH) and next generation sequencing (NGS) were performed. Relevant literature was reviewed.Results:There were one male and one female patients, aged 35 and 29 years, respectively. The tumors developed in the somatic soft tissue, including calf and chest wall, and were 6.0 and 6.2 cm in size, respectively. The imaging studies suggested space-occupying lesions in muscle tissue. Case 1 did not involve the bone, while Case 2 showed fracture of the 8th rib. Microscopically, a fibrous pseudocapsule surrounded by lymphocytes and plasma cells was identified. The tumors were composed of small to medium-sized round and short spindle-shaped cells, showing nodular or sheet-like pattern. The tumor cells showed round nuclear outline, coarse chromatin with prominent nucleoli. Immunohistochemically, tumor cells showed diffuse positivity of ALK (D5F3), MUM1 and Syn, focal or patchy positivity of CKpan, EMA, S-100, NSE, WT-1 and SMA, and a high Ki-67 index (20%-30%). FISH demonstrated break-apart signals of EWSR1 gene in the 2 cases. NGS revealed EWSR1::CREM gene fusion. Case 2 showed an ATRX gene mutation. The two patients were free of recurrence or metastasis at the 10-month and 1-month follow-up, respectively.Conclusions:EWSR1::CREM fusion malignant epithelioid neoplasm is rare and lacks distinctive morphological and immunohistochemical features. FISH and NGS can help make a definitive diagnosis.

Objective:To observe the clinical efficacy of laparoscopic non mesh vaginal sacral fixation(LSC)in the treatment of pelvic organ prolapse(POP)patients with mainly middle pelvic defects.Methods:55 cases of laparoscopic non mesh LSC patients with POP with mainly middle pelvic defects were selected from August 2019 to February 2023 at Liuzhou Hospital of Guangzhou Women and Children's Medical Center.The surgical condition of POP patients were observed.Patients were followed up after surgery,the position and recurrence of the anterior vaginal wall(Ba)point,posterior vaginal wall(Bp)point,and vaginal apex(C)point in POP patients before and after surgery were observed.The preoperative and postoperative pelvic floor dysfunction questionnaire scores of POP patients treated by laparoscopic non mesh LSC were compared.And the occurrence of short-term and long-term complications in POP patients after surgery were observed.Results:Among the 55 POP patients with laparoscopic non mesh LSC,11 underwent bilateral adnexectomy,3 underwent bilateral salpingectomy,55 underwent anterior vaginal wall repair,28 underwent posterior vaginal wall repair,2 underwent paravaginal repair,and 28 underwent perineal laceration repair.Additionally,2 underwent tension free mid urethral suspension via the pubic posterior vaginal wall,and 3 underwent mid urethral folding.The average duration of the surgery was(197.8±48.7)minutes,and the intraoperative blood loss was 50(30,50)mL.The postoperative indwelling time of the urinary catheter was 2.0(1,3)days,the postoperative residual urine volume was 6(0,11)mL,and the hospital stay was 10(8,12)days.Among the 55 POP patients,all surgeries were successful,with a success rate of 100％.The follow-up period ended in September 2024,with an average follow-up time of(42.14±11.37)months.2 cases were lost to follow-up,and 53 patients were successfully followed up,including 48 outpatient follow-up patients and 5 telephone follow-up patients.Among the 48 outpatient follow-up patients,1 case had a recurrence of the anterior vaginal wall,with a recurrence rate of 2.08％(1/48).The patient did not undergo anterior vaginal wall repair during surgery,and after surgery,the patient felt that there was a mass protruding from the vagina.However,the symptoms improved on their own after rest,and no further surgery was performed.The comparison of Ba points,C points,and Bp points before and after surgery in 48 outpatient follow-up patients showed statistically significant differences(P＜0.05).The comparison of preoperative and postoperative pelvic organ prolapse distress inventory(POPDI),Urogenital distress inventory(UDI),and Pelvic Floor Distress Inventory-short From-20(PFDI-20)scores among 53 POP patients showed statistically significant differences(P＜0.05),there was no statistically significant difference in preoperative and postoperative colorectal-anal distress inventory(CRADI)scores among the 53 POP patients(P＞0.05).There were a total of 11 cases of postoperative complications in 55 POP patients,including 1 case of enteritis,2 cases of urinary tract infections,1 case of bladder injury,1 case of lower back pain,pelvic pain,and difficulty defecation,and 5 cases of newly developed urinary incontinence.The incidence of complications was 20.00％(11/55).The long-term follow-up results of POP patients showed that 4 patients had no sexual activity after surgery,and 49 patients resumed sexual activity after surgery,among them,47 patients reported an improvement in their sexual experience compared to before surgery,accounting for 95.92％(47/49).Two patients were unable to have normal sexual activity due to painful intercourse,accounting for 4.08％(2/49).Conclusion:Laparoscopic non mesh LSC treatment for POP patients with mainly middle pelvic defects has a high success rate,few complications,good short-term and long-term follow-up effects,and can significantly improve pelvic floor dysfunction symptoms.

TAFRO syndrome is a systemic inflammatory disease with unknown etiology.It has low incidence rate and progresses rapidly,which poses a significant challenge for clinicians to make a timely diagnosis and provide reasonable treatment.This article retrospectively analyzed a 65-year-old male patient with iMCD-TAFRO admitted to Minhang Hospital,Fudan University,and visited the Department of Nephrology due to bilateral lower limb edema.The patient exhibited systemic edema,fever,and multiple enlarged lymph nodes.A comprehensive examination showed thrombocytopenia,renal dysfunction,elevated CRP levels,multiple serosal fluid accumulations,and bone marrow reticulin fibrosis.For further diagnosis and treatment,he visited the Hematology Clinic of Zhongshan Hospital,Fudan University.Based on the clinical manifestations,the diagnosis of TAFRO syndrome was considered.After further lymph node pathological consultation,the diagnosis was confirmed as idiopathic multicentric Castleman disease(iMCD)-TAFRO syndrome.Later,the patient was transferred to the hematology department of Minhang Hospital,Fudan University.After 15 days of treatment with methylprednisolone,cyclosporine A,rituximab,and thrombopoietin,there was no significant improvement in the condition.Due to personal reasons,the patient discontinued further treatment and passed away 2 weeks later.
