IgA nephropathy (IgAN) is a glomerulonephritis characterized by diffuse deposition of immune complexes mainly composed of IgA in the mesangial area of the glomerulus. However, some patients show monotypic IgA deposits in the immunofluorescence examination, and its clinicopathological significance is not yet clear. The renal pathological changes of IgAN with monotypic IgA deposition are similar to those of proliferative glomerulonephritis with monoclonal IgA deposit (IgA-PGNMID), which has a risk of progressing to hematological malignancies and a worse clinical prognosis. It is necessary to differentiate them based on clinical pathological manifestations and hematological examinations. Based on previous literature reports and the research results of our research group, this review summarizes and analyzes the mechanism, clinical and pathological characteristics, and prognosis of IgAN with monotypic IgA deposition, and the relationship between IgAN with monotypic IgA deposition and IgA-PGNMID, to improve clinical doctors' understanding of IgAN with monotypic IgA deposition, reduce missed diagnosis and misdiagnosis, and improve patients' prognosis.

BACKGROUND:Current treatment strategies for chronic non-healing wounds have shown unsatisfactory results,necessitating the exploration of novel therapeutic approaches.Concentrated growth factors,rich in high-concentration growth factors and possessing a stable natural three-dimensional structure,have demonstrated significant application value in the treatment of chronic non-healing wounds.OBJECTIVE:To review the current status of concentrated growth factor application in chronic non-healing wounds,analyze the shortcomings of concentrated growth factor in clinical applications,and propose constructive suggestions and prospects.METHODS:CNKI,WanFang,and VIP databases were searched with the key words of"concentrated growth factor,platelet concentrate products,chronic wound,chronic ulcer,wound healing,platelet-rich plasma,platelet-rich fibrin"in Chinese.PubMed was searched with the key words of"CGF,concentrated growth factor,platelet concentrate products,chronic wound,chronic ulcer,wound healing,PRP,PRF,platelet-rich plasma,platelet-rich fibrin"in English.The articles published from 2000 to 2024 were searched and further analyzed and summarized after screening.RESULTS AND CONCLUSION:Concentrated growth factor,with its diverse application forms,high concentration of growth factors,natural three-dimensional structure,compatibility with various material technologies,relatively low cost,and ease of operation,has demonstrated significant clinical value in the treatment of chronic wounds.Numerous researchers have validated its positive effects in chronic wound therapy through clinical applications.However,there is currently no clear consensus on standardized concentrated growth factor application protocols,and certain deficiencies have been revealed in practical applications,including issues with dosage,centrifugation settngs,identification schemes,and preparation methods for different forms of concentrated growth factor.There is substantial room for research on concentrated growth factor,and it is believed that with a clear consensus on its application in the future,concentrated growth factor could play a significant role in clinical practice.

Objective:To preliminarily explore the clinical value of three-dimensional ultrasound fusion imaging(3DUS FI) visualization technology in guiding precise needle placement during thermal ablation of hepatocellular carcinoma (HCC).Methods:A total of 56 HCC patients (59 lesions)who underwent 3DUS FI guided thermal ablation were retrospectively analyzed in the First Affiliated Hospital of Sun Yat-sen University from November 2019 to December 2021. All patients were collected with three-dimensional ultrasound volume image before ablation which were fused with real-time two-dimensional ultrasound image for registration, and then the tumor and the safety margin of 5 mm were segmented and marked. Finally, the thermal ablation was performed under three-dimensional visualization. Contrast-enhanced CT/MRI was performed 1 month after thermal ablation to evaluate whether the lesion was completely ablated and measure the ablative margin, and the relationship between ablative margin and the incidence of local tumor progression (LTP) was also analyzed.Results:During the ablation, all lesions could be successfully registered and displayed in three-dimension. Postoperative contrast-enhanced ultrasound showed that all lesions were completely ablated. A total of 37 lesions could be evaluated for ablative efficacy and ablative margin based on contrast-enhanced CT/MRI 1 month after themal ablation, of which 32 (86.5%) lesions achieved complete ablation and obtained at least 5 mm ablative margin. During the follow-up period, LTP was occurred in 4 lesions, 3 of the lesions occurred at the ablative margin< 5 mm. Both 1-year and 2-year cumulative LTP rates were all 7.1%. None of patients had serious complications or deaths associated with thermal ablation.Conclusions:3DUS FI real-time guidance technology is feasible and safe in visually guiding precise needle placement during thermal ablation of HCC.

Objective:To explore the value of ultrasound fusion navigation technology in the biopsy of parapharyngeal-infratemporal fossa-skull base (PIS) lesions.Methods:This study was conducted at the First Affiliated Hospital of Sun Yat-Sen University from March 2021 to March 2022 and included 8 patients [3 females and 5 males; age, (50±20) years; range, 16-76 years] with PIS lesions who needed to clarify the pathological diagnosis. The ultrasound fusion navigation with CT or MRI was used to guide lesion biopsy, and the technical feasibility, pathological diagnostic results and complications were evaluated.Results:The biopsy procedures were successful in all 8 patients, and the lesion size ranged from 2.2 to 6.5 cm. The exact pathological diagnosis was obtained in 7 patients, and the diagnostic rate was 87.5% (7/8). No major complication was observed after the biopsy. Mild complications occurred in 1 case, with a incidence of 12.5% (1/8).Conclusions:Ultrasound fusion navigation-guided biopsy is feasible, effective, and safe in the biopsy of deep head and neck lesions.

Objective:To investigate the short-term efficacy of thoracoscopic radical surgery in the treatment of esophageal cancer and its influence on the expression of trigger receptor-1 (TRE-1) and tumor necrosis factor receptor-associated protein 1 (TRAP1).Methods:A total of 68 patients with esophageal cancer who were admitted to First People′s Hospital of Ningyang from June 2016 to June 2019 were selected and divided into thoracoscope radical surgery group and raditional surgery group by stratified sampling method, with 34 cases in each group. The thoracoscopic radical surgery group was treated with thoracoscopic radical surgery, and the traditional surgery group was treated with traditional open radical esophageal cancer surgery with neck, chest, and abdominal incisions. The levels of inflammatory factors, immune function, lung function indexes, TREM-1, TRAP1 expression and complications of the two groups were observed and compared.Results:Before operation, the levels of inflammatory factors tumor necrosis factor (TNF)-α, interleukin (IL)-6, IL-10 in two groups had no significant differences ( P>0.05). At 2 d after operation, the levels of TNF-α, IL-6, IL-10 in two groups were increased and the levels of above index in the thoracoscopic radical surgery group were lower than those in the traditional surgery group: (23.21 ± 0.32) mg/L vs. (29.69 ± 0.48) mg/L, (232.15 ± 23.64) ng/L vs. (246.73 ± 25.89) ng/L, (0.64 ± 0.19) ng/L vs. (0.89 ± 0.21) ng/L, and there were statistical differences ( P<0.05). Before operation, the levels of CD 3+, CD 4+, CD 8+, and CD 4+/CD 8+ in two groups had no significant differences ( P>0.05). At 2 d after operation, the levels of CD 3+, CD 4+, CD 8+ decreased and the level of CD 4+/CD 8+ increased, and the levels of CD 3+, CD 4+, CD 8+, CD 4+/CD 8+ in the thoracoscopic radical surgery group were higher than those in the traditional surgery group: (46.78 ± 1a2.43)% vs. (41.32 ± 9.36)%, (46.12 ± 9.68)% vs. (41.59 ± 7.98)%, (27.42 ± 4.27)% vs. (21.38 ± 3.16)%, 1.47 ± 0.46 vs. 1.25 ± 0.27, and there were statistical differences ( P<0.05). Before operation, the levels of forced expiratory volume in one second (FEV 1), forced vital capacity (FVC), FEV 1/FVC in two groups had no significant differences ( P>0.05). At 2 day after operation, the levels of FEV 1, FVC, FEV 1/FVC in two groups decreased, and the levels of FEV 1, FVC, FEV 1/FVC in the thoracoscopic radical surgery group were higher than those in the traditional surgery group: (2.37 ± 0.72) L vs. (1.82 ± 0.53) L, (3.34 ± 1.06) L vs. (2.43 ± 0.82) L, (62.47 ± 15.26)% vs. (53.67 ± 12.28)%, and there were statistical differences ( P<0.05).Before operation, the expression of TREM-1 and TRAP1 in two groups had no significant differences ( P>0.05). At 2 d after operation, the expression of TREM-1in the thoracoscopic radical surgery group was higher than that of traditional surgery group: (141.56 ± 34.69 vs. 121.54 ± 22.75); the expression of TRAP1 was lower than that of the traditional surgery group: (1.63 ± 0.51 vs. 2.11 ± 0.64), and there were statistical differences ( P<0.05). The postoperative complication rate of the thoracoscopic radical surgery group was lower than that of the traditional surgery group:5.88%(2/34) vs. 23.53%(8/34), and there was statistical difference ( χ2=4.221, P=0.040). Conclusions:The short-term efficacy of thoracoscopic radical surgery in the treatment of esophageal cancer is better than that of the traditional surgery group, which can increase the expression of TREM-1, reduce the expression of TRAP1, and reduce the inflammatory response and the impact on the immune function.

Objective:To analyze the gray-scale ultrasound and contrast-enhanced ultrasound features in secondary hyperparathyroidism (SHPT) to construct a clinical and ultrasound-based model, and to investigate the relationship between this model and serum intact parathyroid hormone(iPTH) level in order to find proper indicators for evaluation of the severity of SHPT.Methods:From February 2016 to March 2021, a total of 59 SHPT patients with 181 parathyroid glands (PTGs) admitted to the First Affiliated Hospital of Sun Yat-Sen University were enrolled. Gray-scale ultrasound and contrast-enhanced ultrasound were performed in every participant. Patients were divided into low-iPTH group ( iPTH<800 ng/L) and high-iPTH group (iPTH≥800 ng/L) according to the serum iPTH level. The characteristics of gray-scale ultrasonic imaging and contrast-enhanced ultrasonic imaging were analyzed by 2 sonographers.Biochemical parameters were collected and combined with ultrasonic characteristics to construct the clinical and ultrasound-based model. The relationship between the model and serum iPTH level was analyzed by multivariate linear regression (stepwise). Independent influencing factors on serum iPTH level was investigated in SHPT patients without iPTH-reducing drugs using history.Results:There were 19 patients in low-iPTH group and 40 patients in high-iPTH group.Serum calcium, serum phosphorus, serum creatinine, PTG number, total PTG volume, blood scores, calcification and cysts scores, CEUS scores (washing-in phase and washing-out phase) were significantly different between two groups(all P<0.05). The multivariate linear regression (stepwise) showed that serum phosphorus, total PTG volume and blood scores were independently related with serum iPTH level (standardized β coefficient were 0.387, 0.254 and 0.242 respectively; all P<0.05). Conclusions:Serum phosphorus, total PTG volume and blood scores are independent influencing factors on serum iPTH level. Ultrasonography combined with clinical parameters can help evaluate the severity of SHPT more accurately.
