Objective: To assess the current status of bacterial detection capabilities in various blood collection and supply and related laboratories across China, and to identify key factors affecting the consistency of test results. Methods: A pooled analysis was conducted on data from 21 external quality assessment (EQA) rounds for blood bacterial detection carried out by the China International Transfusion Infection Prevention and Control (CITIC) project from 2019 to 2025. The study covered three types of laboratories-blood centers, central blood stations, and commercial laboratories—across 23 provincial-level administrative regions in China. Statistics were compiled on the number of participating laboratories, and the concordance rates were calculated for different institution types, different automated blood culture systems, different bacterial concentrations, and different strains. Non-standard reporting issues were also reviewed, and statistical methods were applied for analysis. Results: Over the seven-year period, the number of participating laboratories increased from 161 to 236, with an average annual growth rate of 6.58%, and the annual concordance rates ranged from 82.61% to 94.92%. The overall laboratory concordance rates for the three types of participating laboratories were all>89.0% (P>0.05), while commercial laboratories showed a significant year-by-year increase (70.97%-100%, P<0.05). The concordance rates of automated blood culture systems from eight manufacturers showed no significant differences (97.98%-100%, P>0.05), indicating stable performance across all devices. The overall sample concordance rate was 98.88%, with negative samples showing a lower rate than positive samples (97.97% vs 99.14%); positive sample rates increased with higher concentrations; and low-concentration Gram-negative bacterial samples had a lower concordance rate than Gram-positive ones (93.15% vs 100%). A total of 50 instances of non-standard result reporting were identified, with incorrect time units accounting for the highest proportion (52.0%). Conclusion The participation scale and overall testing proficiency of blood collection and supply and related laboratories nationwide have improved year by year, and all types of automated blood culture devices can meet the requirements for blood bacterial screening. Detection of negative and low-concentration positive samples remains a weak link in current bacterial EQA, and the standardization of laboratory data reporting requires further strengthening. Continuous: external quality assessment, targeted training, and standardized reporting procedures can effectively enhance the homogenization level of blood bacterial testing across the country and ensure the safety of clinical transfusion.

Viral pneumonia in the Lancang-Mekong River Basin exhibits distinct regional epidemiological characteristics and pathogenic mechanisms. Filthy dampness constitutes the core pathogenic factor of the disease here, and the core pathogenesis lies in the yang failing to be stored in the you (酉) position. Clinically, the fundamental therapeutic principle is established as boosting qi to expel filth and guiding yang qi to descend and converge into the you position. In the early stage, the pathogenesis is characterized by the pervasive diffusion of filthy dampness, yang qi floating externally and failing to be stored, and the lung failing to diffuse qi. The treatment focuses on invigorating yang qi to dispel filth and dredging the you pathways, primarily using modified Ganlu Xiaodu Decoction (甘露消毒丹). In the progressive stage, the pathogenesis involves the tenacious stagnation of filthy dampness, yang constraint transforming into heat, and the rampant spread of heat-toxins. The therapeutic approach shifts to acrid medicinals for opening and bitter medicinals for promoting descent, rectifying healthy qi to expel filth, utilizing modified Dayuan Beverage (达原饮). In the recovery stage, filthy dampness gradually recedes, accompanied by the depletion of qi and yin, and insufficient kidney yang. The treatment emphasizes supplementing qi and nourishing yin, accompanied by warming yang, with modified Yunv Decoction (玉女煎).

Objective To explore and verify the prognostic value of endothelial cells in glioblastoma. Methods Through bioinformatics analysis of the TCGA and CGGA databases, we screened endothelial cell-related markers in GBM single-cell data according to a series of criteria. Moreover, univariate Cox regression analysis was performed to obtain and screen endothelial cell prognosis-related markers and construct endothelial cell-related prognostic risk score. qPCR experiments was used to verify the differences in the expression of prognostic markers in GBM tissues and peritumoral normal brain tissues. Kaplan-Meier method was used to construct the survival curve to identify the prognostic efficacy of the prognostic risk score. Results A total of 2 115 prognostic genes of glioblastoma (GBM) were screened. Among them, 1 494 was upregulated and 621 was downregulated. Seven groups of cells were obtained after GBM single-cell sequencing analysis, including AC-like tumor cells, endothelial cells, monocytes/macrophages, NB-like tumor cells, neurons, OC-like tumor cells, and OPC-like tumor cells. According to the differential genes of endothelial cells and the corresponding screening criteria, four genes (DUSP6, STC1, VWA1, and TM4SF1) were screened for risk-score construction. The expression of the target gene in GBM tissues and normal brain tissues around the tumor was significantly up-regulated detected by qPCR. The risk score=0.171*DUSP6+0.144*STC1+0.041*VWA1−0.004*TM4SF1. Conclusion The glioblastoma endothelial cells’ risk score determined in this study can preferably predict the prognosis of patients.

Objective:To investigate the staging criteria of renal tuberculosis,and to analyze the diagnostic and therapeutic characteristics as well as prognostic outcomes at different stages.Methods:A retrospective analysis was conducted on the clinical data of 134 patients with renal tuberculosis who were admitted to the Second Hospital of Lanzhou University between January 2019 and December 2023.The study cohort included 62 males and 72 females,with a mean age of(46.63 ± 13.52)years and a mean body mass index(BMI)of(22.85 ± 3.73)kg/m 2. A total of 107 patients resided in rural areas. Sixty patients had a history of pulmonary tuberculosis. Tuberculous lesions were located in the left kidney in 72 cases and in the right kidney in 62 cases. The main presenting complaints included irritative lower urinary tract symptoms in 85 patients and systemic symptoms in 92 patients. Ureteral involvement was observed in 97 patients,bladder involvement in 32 patients,and genital involvement in 9 patients. Based on computed tomography(CT)findings,the number,extent,and degree of renal destruction caused by tuberculous lesions were comprehensively evaluated in axial,coronal,and sagittal planes. The primary staging criteria included lesion diameter(2 cm)and the proportion of renal volume involved by the lesion(one-third,one-half,and two-thirds). Renal tuberculosis was classified into three stages and six subtypes:Stage Ⅰa,a solitary lesion with a diameter ≤ 2 cm;Stage Ⅰb,a solitary lesion >2 cm or multiple lesions confined within one-third of the renal volume;Stage Ⅱa,lesions involving more than one-third but confined within one-half of the renal volume;Stage Ⅱb,lesions involving more than one-half but confined within two-thirds of the renal volume;Stage Ⅲa,lesions involving more than two-thirds of the renal volume with a glomerular filtration rate(GFR)of the affected kidney <10 ml/min;and Stage Ⅲb,complete renal calcification,presenting as an “autonephrectomy”. Among the 134 patients included in this study,7 were classified as Stage Ⅰa,17 as Stage Ⅰb,20 as Stage Ⅱa,19 as Stage Ⅱb,62 as Stage Ⅲa,and 9 as Stage Ⅲb. The severity of hydronephrosis was graded as follows:mild,renal pelvic separation <2 cm;moderate,2-3 cm;and severe,>3 cm. Prior to treatment,the mean renal pelvic separation was(1.76 ± 0.92)cm in Stage Ⅰa,(1.69 ± 0.81)cm in Stage Ⅰb,and(1.10 ± 0.82)cm in Stage Ⅱa,corresponding to mild to moderate hydronephrosis. All 7 patients in Stage Ⅰa underwent ureteroscopic examination and double-J stent placement,combined with a 6-month short-course anti-tuberculosis regimen consisting of isoniazid,rifampicin,pyrazinamide,and ethambutol for 2 months(intensive phase),followed by isoniazid and rifampicin for 4 months(continuation phase). Among the 17 patients in Stage Ⅰb,13 presented with hydronephrosis and underwent ureteroscopic examination and double-J stent placement in combination with 6 months of anti-tuberculosis therapy,while 4 patients with isolated renal tuberculosis received anti-tuberculosis therapy alone for 6 months.Of the 20 patients in Stage Ⅱa,4 with hydronephrosis underwent ureteroscopic examination and double-J stent placement plus 6 months of anti-tuberculosis therapy,whereas 16 underwent nephroureterectomy. All 19 patients in Stage Ⅱb underwent nephroureterectomy. Among the 62 patients in Stage Ⅲa,60 underwent nephroureterectomy,while 2 refused surgery and were treated with the 6-month short-course anti-tuberculosis regimen. Of the 9 patients in Stage Ⅲb,8 underwent nephroureterectomy;in 1 patient,surgery was not performed due to severe adhesions in the operative field,and the patient received the 6-month short-course anti-tuberculosis regimen instead. Follow-up assessments included clinical symptoms,erythrocyte sedimentation rate(ESR),serum creatinine,degree of renal pelvic separation,and imaging findings from urinary tract CT. Efficacy was evaluated according to the following criteria:Cure was defined as clinical stability with all of the following conditions:① improvement of systemic symptoms,including absence of flank pain,fever,and lower urinary tract irritative symptoms,with normalization of erythrocyte sedimentation rate(ESR);② negative urine culture for Mycobacterium tuberculosis;and ③ complete calcification of renal lesions and/or no evidence of tuberculous lesions at other sites. Stable disease was defined as no change in the size or extent of renal tuberculosis lesions. Progressive disease was defined as enlargement or increase in the number of tuberculous lesions or involvement of additional sites. Results:Among the 7 patients in Stage Ⅰa,follow-up imaging after treatment showed a mean renal pelvic separation of(0.44 ± 0.56)cm,which was significantly reduced compared with baseline( t = 3.909, P = 0.008). Five patients achieved cure,1 remained stable,and 1 showed disease progression and subsequently underwent nephroureterectomy,resulting in postoperative cure. In Stage Ⅰb,among 13 patients with hydronephrosis,post-treatment imaging showed a mean renal pelvic separation of(0.8 ± 0.75)cm,a statistically significant improvement from baseline( t = 5.633, P < 0.01). Six patients were cured,4 remained stable,and 3 experienced disease progression and underwent nephroureterectomy. Of the 4 patients with isolated renal tuberculosis,2 were controlled,and 2 progressed and underwent nephroureterectomy. In Stage Ⅱa,among 4 patients with tuberculous hydronephrosis,post-treatment renal pelvic separation was(1.20±0.98)cm,with no significant difference from baseline( t = -1.675, P = 0.193);these patients underwent nephroureterectomy 1-2 years later. The remaining 16 patients without hydronephrosis underwent nephroureterectomy and were cured. All 19 patients in Stage Ⅱb underwent nephroureterectomy;17 were cured,and 2 developed ipsilateral perirenal fluid collections 3 months postoperatively,which resolved spontaneously with the standard 6-month anti-tuberculosis regimen. Among 62 patients in Stage Ⅲa,60 underwent nephroureterectomy. Of these,54 were cured;1 developed a urinary tract infection within 2 weeks postoperatively;3 showed contralateral renal disease progression at 3 months;and 1 developed ipsilateral perirenal fluid at 3 months,which resolved spontaneously with standard anti-tuberculosis therapy. One patient developed solitary kidney failure 7 months postoperatively and underwent ureteral stent placement,with disease remaining stable thereafter. Two patients refused surgery and received only anti-tuberculosis therapy;during follow-up,1 patient experienced disease progression and died of disseminated tuberculosis after 1 year,while the other developed contralateral renal involvement at 3 months and received standard 6-month therapy,with disease remaining stable. Among 9 patients in Stage Ⅲb,8 underwent nephroureterectomy and were cured. One patient,with severe adhesions precluding surgery,received anti-tuberculosis therapy alone,and disease remained stable over a 2-year follow-up. Conclusions:The CT-based staging system for renal tuberculosis proposed in this study(three stages and six subtypes)effectively reflects the severity of renal lesions and clearly delineates the clinical characteristics and prognostic outcomes at each stage. Stage Ⅰ patients treated with anti-tuberculosis drugs combined with double-J stent placement demonstrated favorable outcomes and high renal preservation rates. In contrast,Stages Ⅱ and Ⅲ patients showed poor responses to anti-tuberculosis therapy combined with drainage,with a higher risk of disease progression and relatively worse prognosis,highlighting the recommendation for early nephroureterectomy of the affected kidney.

Undifferentiated spindle cell sarcoma of the prostate is clinically rare. This article reports a case of a 29-year-old male who presented on February 7,2022,with a two-week history of localized pain in the perineal area and spermatic cord. The diagnosis of prostatic undifferentiated spindle cell sarcoma was confirmed by imaging studies and prostate needle biopsy pathology. After consultation by the urologic oncology multidisciplinary team and considering the patient's preference,a treatment plan of radical radiotherapy combined with chemotherapy,immunotherapy,and targeted therapy was adopted,Partial stereotactic body radiotherapy(P-SBRT)was delivered to the tumor center with a total dose of 74.4 Gy,combined with cisplatin and pembrolizumab. Lung metastasis progression occurred 1.5 months after radiotherapy,and treatment was switched to a combination of pirarubicin,ifosfamide,pembrolizumab,and bevacizumab. After 39 months of follow-up,the disease remained well-controlled with preserved organ function and long-term survival. This case,utilizing a multidisciplinary comprehensive diagnosis and treatment model,provides a reference for organ-preserving non-surgical management in patients with prostate soft tissue sarcoma.

Biological clock is a pattern of rhythms in which organisms exhibit cycles approaching 24 h in order to adapt to periodic changes in the external environment.Gut microbiota is the sum of extremely large number of microorganisms parasitized in humans and animals.Disorders of the biological clock increase the risk of metabolic diseases,and the occurrence of these disorders is closely related to the interaction with the dysbiosis of the gut microbiota.With the deepening of the understanding of the brain-gut axis,targeting gut microbiota to ameliorate biological clock disorders and associated diseases has achieved major theoretical breakthroughs and was partially applied in clinical practice,including dietary interventions such as time restricted feeding,development of microbial-related products(probiotics and postbiotics),and fecal microbiota transplantation.This article reviews the research progress of intestinal flora and rhythmicity,as well as targeting intestinal flora for the treatment of biological clock disorders,so as to provide new ideas for the prevention and treatment of rhythm disorders and concurrent diseases.

Tongue squamous cell carcinoma (TSCC) is a prevalent malignancy that afflicts the head and neck area and presents a high incidence of metastasis and invasion. Accurate diagnosis and effective treatment are essential for enhancing the quality of life and the survival rates of TSCC patients. The current treatment modalities for TSCC frequently suffer from a lack of specificity and efficacy. Nanoparticles with diagnostic and photothermal therapeutic properties may offer a new approach for the targeted therapy of TSCC. However, inadequate accumulation of photosensitizers at the tumor site diminishes the efficacy of photothermal therapy (PTT). This study modified gold nanodots (AuNDs) with the TSCC-targeting peptide HN-1 to improve the selectivity and therapeutic effects of PTT. The Au-HN-1 nanosystem effectively targeted the TSCC cells and was rapidly delivered to the tumor tissues compared to the AuNDs. The enhanced accumulation of photosensitizing agents at tumor sites achieved significant PTT effects in a mouse model of TSCC. Moreover, owing to its stable long-term fluorescence and high X-ray attenuation coefficient, the Au-HN-1 nanosystem can be used for fluorescence and computed tomography imaging of TSCC, rendering it useful for early tumor detection and accurate delineation of surgical margins. In conclusion, Au-HN-1 represents a promising nanomedicine for imaging-based diagnosis and targeted PTT of TSCC.

BackgroundPostpartum depression (PPD) is a prevalent postpartum complications that significantly compromises women's psychological and physical well-being. Repetitive transcranial magnetic stimulation (rTMS), a conventional neuromodulation technique, has been increasingly used in the treatment of PPD. However, high-quality evidence regarding its efficacy and safety remains limited. ObjectiveTo evaluate the efficacy and safety of rTMS in the treatment of PPD, thereby providing references for clinical treatment. MethodsDatabases including Cochrane Library, PubMed, Embase, CNKI, Wanfang, VIP and China Biology Medicine disc (CBM) were electronically searched for randomized controlled trials (RCTs) on rTMS for PPD, with the search spanning from database inception to February 8, 2025. Study quality was assessed using the Cochrane Handbook for Systematic Reviews of Interventions 5.0.1, and the certainty of evidence was graded according to the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. Meta-analysis was conducted using RevMan 5.3 and Stata 12.0. The outcomes of the Meta-analysis included the total effective rate, Edinburgh Postnatal Depression Scale (EPDS) score, Hamilton Depression Rating Scale (HAMD) score, and adverse reactions (dizziness, headache, nausea, diarrhea, and the overall incidence of adverse reactions). ResultsA total of 11 studies involving 729 patients with PPD were included. Meta-analysis results showed that the total effective rate in the study group was significantly higher than that in the control group (OR=5.54, 95% CI: 3.07–10.01, P<0.01). Both EPDS score (SMD=-2.38, 95% CI: -3.39–-1.37, P<0.01) and HAMD score (SMD=2.53, 95% CI: 1.21–3.85, P<0.01) in the study group were significantly lower than those in the control group, with statistically significant differences. Comparisons between the study group and control group reveal no significant differences in the incidence of dizziness and headache (RR=1.47, 95% CI: 0.63–3.43, P>0.05), nausea (RR=1.46, 95% CI: 0.55–3.86, P>0.05), diarrhea (RR=0.71, 95% CI: 0.23–2.20, P>0.05), and overall adverse reactions (RR=1.30, 95% CI: 0.79–2.15, P>0.05). GRADE assessment rated the four indicators of dizziness and headache, diarrhea, overall incidence of adverse reactions, and EPDS score as "moderate-certainty evidence", and rated the total effective rate, nausea, and the HAMD score as "low-certainty evidence". ConclusionrTMS demonstrates certain therapeutic efficacy for PPD, with a safety profile comparable to conventional treatment.
