Virus-related lymphoma exhibits a dual nature as both a hematologic malignancy and a viral infectious disease， making it more resistant to treatment and associated with poorer prognosis. This paper analyzes the understanding and therapeutic advantages of traditional Chinese medicine （TCM） in virus-related lymphoma. It proposes a TCM-based approach centered around syndrome differentiation， using standardized measurements of the overall TCM condition， multi-omics research of hematologic tumors， and artificial intelligence technologies to identify the "pre-condition" of virus-related lymphoma. A risk warning model will be established to early identify high-risk populations with viral infections that may develop into malignant lymphoma， thereby establishing a risk warning system for virus-related lymphoma. At the same time， a TCM health management approach will be applied to manage and regulate virus-related lymphoma， interrupting its progression and forming a human-centered， comprehensive， continuous health service model. Based on this， a standardized， integrated clinical prevention and treatment decision-making model for virus-related lymphoma， recognized by both Chinese and western medicine， will be established to provide TCM solutions for primary prevention of major malignant tumors.

Objective: To investigate the distribution of traditional Chinese medicine (TCM) syndromes and syndrome elements in lymphoma, as well as the correlation between TCM syndromes and Western clinical indicators, in order to analyze associations between TCM syndromes and these indicators. Methods: From January 2023 to May 2024, 216 patients with lymphoma who met the inclusion criteria in the Department of Hematology, Third People′s Hospital Affiliated to Fujian University of Traditional Chinese Medicine were enrolled. Four diagnostic methods were applied to perform TCM syndrome differentiation and extract syndrome elements. The correlations between various syndromes and blood test indicators of lactate dehydrogenase (LDH), β2-microglobulin (β2-MG), immunoglobulin G (IgG), immunoglobulin M (IgM), immunoglobulin A (IgA), white blood cell (WBC), hemoglobin (Hb), platelet count (PLT), neutrophil (NEUT), immunohistochemical markers of B-cell lymphoma-6 (BCL6), B-cell lymphoma-2 (BCL2), proto-oncogene MYC, and Ki67 protein expression, Ann Arbor staging, international prognostic index (IPI) score, bone marrow infiltration, concurrent infections during chemotherapy, and post-chemotherapy bone marrow suppression rate were analyzed. Results: Five TCM syndromes, ranked by frequency, were syndromes of yin deficiency with phlegm accumulation(41.67%), qi depression with phlegm obstruction(30.56%), cold-phlegm congelation and stagnation(12.96%), phlegm-blood stasis toxin(12.04%), and lingering pathogen due to deficient vital qi(2.77%). Yin deficiency(50.93%) and phlegm(45.37%) were the more prevalent syndrome elements. The TCM syndromes were correlated with β2-MG, PLT, MYC, BCL2/MYC, Ki67 protein expression, and bone marrow infiltration (P<0.05). No statistically significant differences were observed in Ann Arbor staging or IPI score across the syndromes. Compared to the syndrome of cold-phlegm congelation and stagnation, the syndrome of qi depression with phlegm obstruction exhibited higher levels of NEUT, MYC, BCL2/MYC, and Ki67 protein expression, as well as a higher rate of post-chemotherapy bone marrow suppression (P<0.05); the syndrome of phlegm-blood stasis toxin showed higher MYC and BCL2/MYC protein expression and a higher rate of post-chemotherapy bone marrow suppression rate (P<0.05); the syndrome of yin deficiency with phlegm accumulation demonstrated higher MYC and BCL2/MYC protein expression and bone marrow infiltration rates, whereas PLT level was lower (P<0.05); the syndrome of lingering pathogen due to deficient vital qi had higher MYC, BCL2/MYC, and Ki67 protein expression levels, as well as a higher rate of post-chemotherapy bone marrow suppression rate (P<0.05). Compared to the syndrome of qi depression with phlegm obstruction, the syndrome of phlegm-blood stasis toxin exhibited lower Ki67 protein expression (P<0.05); the syndrome of yin deficiency with phlegm accumulation had higher β2-MG level, bone marrow infiltration rate, and rate of concurrent infections during chemotherapy, whereas PLT and NEUT levels and the rate of post-chemotherapy bone marrow suppression rate were lower (P<0.05). Compared to the syndrome of phlegm-blood stasis toxin, the syndrome of yin deficiency with phlegm accumulation had higher β2-MG level, whereas NEUT and the rate of post-chemotherapy bone marrow suppression were lower(P<0.05); the syndrome of lingering pathogen due to deficient vital qi exhibited a higher Ki67 protein expression (P<0.05). Compared to the syndrome of yin deficiency with phlegm accumulation, the syndrome of lingering pathogen due to deficient vital qi also showed a higher Ki67 protein expression(P<0.05). Conclusion The syndrome of yin deficiency with phlegm accumulation is relatively common in lymphoma. There is a correlation between TCM syndromes and Western medicine clinical indicators. The presence of heat signs in the syndromes may indicate active disease and poor prognosis, while the presence of strong pathogenic factors and weak vital qi in the syndromes may indicate a severer chemotherapy-related bone marrow suppression.

【Objective】 To investigate the prognostic value of tumor location in patients with upper tract urothelial carcinoma (UTUC) treated with radical nephroureterectomy (RNU), and to develop and validate a nomogram model for predicting the overall survival (OS). 【Methods】 UTUC patients undergoing RUN at our hospital during Jan.2010 and Dec.2022 were retrospectively collected, 70% of whom were included in the training group and 30% in the validation group.According to the tumor location, patients were divided into renal pelvis tumor (RPT) group and ureteral tumor (UT) group.The differences in clinicopathological features and prognosis were analyzed.Based on multivariate Cox results, a nomogram model for predicting OS was developed and validated. 【Results】 A total of 366 patients (196 RPT and 170 UT) were included in this study.There were statistically significantly differences in urine cytology (P=0.001), hydronephrosis (P<0.001), history of bladder tumor (P=0.021), pathological T stage (P<0.001) and histological structure (P=0.037) between the two groups.Multivariate Cox results showed that patients with UT had a worse prognosis (HR=2.00, 95%CI: 1.22-3.27, P=0.006).Factors of the nomogram for predicting OS included age, tumor location, lymphovascular invasion and pathological T stage.The model showed good discrimination and calibration, and performed well in internal verification. 【Conclusion】 Compared with RPT, UT has a worse prognosis and the fat around the tumor should be surgically removed more thoroughly to avoid micro-residual.We successfully coustructed a nomogram model that can be used to predict the OS of UTUC patients after RNU surgery.

Objective To evaluate the value of systemic inflammatory markers(SIM)in the prognosis of patients with bladder cancer undergoing radical cystectomy.Methods Clinical data of 233 patients with bladder cancer who underwent radical cystectomy in the Affiliated Hospital of Xuzhou Medical University during Dec.2011 and Nov.2020 were retrospectively collected,the SIM score was calculated and patients were grouped.Progression-free survival(PFS)was assessed with Kaplan-Meier analysis,and differences between groups were compared with log-rank test.Factors affecting PFS were analyzed with Cox proportional risk model.The patients were randomly divided into a training set(n=164)and a verification set(n=69)according to 7:3 ratio,and a nomogram model was established and verified.Results Cox regression analysis showed that SIM score and pathological T staging were independent predictors of PFS(P＜0.05).A predictive model was established based on SIM score and pathological T staging.The area under the receiver operating characteristic(AUC)curve for predicting 1-year,3-year,and 5-year PFS were 0.939,0.943,and 0.943,respectively.After the model was applied to evaluate the validation set,the performance was still stable.Conclusion The prediction model based on SIM score and clinicopathological T staging can accurately predict the survival of patients with bladder cancer after radical cystectomy,and can be used to guide individualized treatment of patients.

Objective:To prepare the chitin/hyaluronic acid/collagen hydrogel loaded with mouse adipose-derived stem cells and to explore its effects on wound healing of full-thickness skin defects in rats.Methods:The research was an experimental research. Chitin nanofibers were prepared by acid hydrolysis and alkaline extraction method, and then mixed with hyaluronic acid and collagen to prepare chitin/hyaluronic acid/collagen hydrogels (hereinafter referred to as hydrogels). Besides, the hydrogels loaded with mouse adipose-derived stem cells were prepared. Thirty male 12-week-old guinea pigs were divided into negative control group, positive control group, and hydrogel group according to the random number table, with 10 guinea pigs in each group. Ethanol, 4-aminobenzoic acid ethyl ester, or the aforementioned prepared hydrogels without cells were topically applied on both sides of back of guinea pigs respectively for induced contact and stimulated contact, and skin edema and erythema formation were observed at 24 and 48 h after stimulated contact. Adipose-derived stem cells from mice were divided into normal control group cultured routinely and hydrogel group cultured with the aforementioned prepared hydrogels without cells. After 3 d of culture, protein expressions of platelet-derived growth factor-D (PDGF-D), insulin-like growth factor-Ⅰ (IGF-Ⅰ), and transforming growth factor β 1 (TGF-β 1) were detected by Western blotting ( n=3). Eight male 8-week-old Sprague-Dawley rats were taken and a circular full-thickness skin defect wound was created on each side of the back. The wounds were divided into blank control group without any treatment and hydrogel group with the aforementioned prepared hydrogels loaded with adipose-derived stem cells applied. Wound healing was observed at 0 (immediately), 2, 4, 8, and 10 d after injury, and the wound healing rate was calculated at 2, 4, 8, and 10 d after injury. Wound tissue samples at 10 d after injury were collected, the new tissue formation was observed by hematoxylin-eosin staining; the concentrations of interleukin-1α (IL-1α), IL-6, IL-4, and IL-10 were detected by enzyme-linked immunosorbent assay method; the expressions of CD16 and CD206 positive cells were observed by immunohistochemical staining and the percentages of positive cells were calculated. The sample numbers in animal experiment were all 8. Results:At 24 h after stimulated contact, no skin edema was observed in the three groups of guinea pigs, and only mild skin erythema was observed in 7 guinea pigs in positive control group. At 48 h after stimulated contact, skin erythema was observed in 8 guinea pigs and skin edema was observed in 4 guinea pigs in positive control group, while no obvious skin erythema or edema was observed in guinea pigs in the other two groups. After 3 d of culture, the protein expression levels of PDGF-D, IGF-I, and TGF-β 1 in adipose-derived stem cells in hydrogel group were significantly higher than those in normal control group (with t values of 12.91, 11.83, and 7.92, respectively, P<0.05). From 0 to 10 d after injury, the wound areas in both groups gradually decreased, and the wounds in hydrogel group were almost completely healed at 10 d after injury. At 4, 8, and 10 d after injury, the wound healing rates in hydrogel group were (38±4)%, (54±5)%, and (69±6)%, respectively, which were significantly higher than (21±6)%, (29±7)%, and (31±7)% in blank control group (with t values of 3.82, 3.97, and 4.05, respectively, Pvalues all <0.05). At 10 d after injury, compared with those in blank control group, the epidermis in wound in hydrogel group was more intact, and there were increases in hair follicles, blood vessels, and other skin appendages. At 10 d after injury, the concentrations of IL-1α and IL-6 in wound tissue in hydrogel group were significantly lower than those in blank control group (with tvalues of 8.21 and 7.99, respectively, P<0.05), while the concentrations of IL-4 and IL-10 were significantly higher than those in blank control group (with tvalues of 6.57 and 9.03, respectively, P<0.05). The percentage of CD16 positive cells in wound tissue in hydrogel group was significantly lower than that in blank control group ( t=8.02, P<0.05), while the percentage of CD206 positive cells was significantly higher than that in blank control group ( t=7.21, P<0.05). Conclusions:The hydrogel loaded with mouse adipose-derived stem cells is non-allergenic, can promote the secretion of growth factors in adipose-derived stem cells, promote the polarization of macrophages to M2 phenotype in wound tissue in rats with full-thickness skin defects, and alleviate inflammatory reaction, thereby promoting wound healing.

Objective:To investigate the efficacy and safety of oral semaglutide in Chinese patients with type 2 diabetes mellitus(T2DM) inadequately controlled by diet and exercise only.Methods:In the randomized, double-blind, multicenter, multinational PIONEER-11 trial, Chinese patients were prospectively randomly assigned to receive oral semaglutide 3, 7, or 14 mg, or placebo. The primary endpoint was the change from baseline in glycated hemoglobin(HbA 1C) at week 26. This is a pre-defined subset analysis to assess the efficacy and safety in Chinese patients. Results:Totally 390 Chinese T2DM patients were enrolled(mean age 51 years), with a T2DM duration of 1.8 years, HbA 1C of 7.9%, and BMI of 26.5 kg/m 2 at baseline. Overall, changes at week 26 from baseline in HbA 1C were -1.1%, -1.6%, -1.6%, and 0.0%, and in bodyweight were -0.7, -1.9, -2.6, and -0.7 kg in oral semaglutide(3, 7, or 14 mg) and placebo groups, respectively. Compared to the placebo group, estimated treatment differences(ETDs) in HbA 1C for the 3, 7, and 14 mg groups were -1.2%(95% CI -1.4, -0.9), -1.7%(95% CI -1.9, -1.4), and -1.6%(95% CI -1.9, -1.4)(all P<0.001), respectively, and in weight loss for the 7 mg and 14 mg groups were -1.2 kg(95% CI -2.1, -0.4; P=0.006) and -1.9 kg(95% CI -2.8, -1.0; P<0.001), respectively. The most frequent gastrointestinal adverse events were diarrhea(oral semaglutide: 3.1%-12.5% vs placebo: 2.0%) and nausea(3.1%-6.3% vs 2.0%), mostly mild in severity and transient. Conclusion:In Chinese patients with T2DM who had insufficient glycemic control with diet and exercise only, oral semaglutide showed better glycemic control at doses of 3, 7, and 14 mg and more weight loss at doses of 7 and 14 mg compared to placebo, with a safety profile consistent with that observed in the global trial population.

Acral melanoma(AM)is the most common histologic subtype of melanoma in dark-skinned patients and is associated with a worse prognosis and a high mortality rate,largely due to the inconspicuous nature of early-stage lesions,which can lead to late diagnosis.Because of the overlapping clinical and histopathological features of AM with other forms of cutaneous melanomas,early detection of AM requires a multidisciplinary approach that integrates various diagnostic modalities,including clinical examination,dermoscopy,histopathology,molecular testing,radiological imaging,and blood tests.While surgery is the preferred method of treatment for AM,other therapeutic options may be employed based on the stage and underlying etiology of the disease.Immune checkpoint inhibitors,molecular targeted therapy,radiotherapy,chemotherapy,and oncolytic virotherapy represent promising advanced treatment options for AM.In this review,we provide an overview of the latest advancements in diagnostic and therapeutic methods for AM,highlighting the importance of early detection and the prompt,individualized management of this challenging disease.

Objective:To understand the status quo of nutrition knowledge, attitude and behavior of nurses in class A tertiary hospital and its influencing factors, and to provide reference for the development of reasonable and standard nutrition training courses.Methods:The knowledge, attitude and behavior of nutrition of 207 nurses in 28 class A tertiary hospitals from 17 provinces cities on October 25-26, 2019 were investigated Questionnaire on Nutritional Knowledge, Attitude and Behavior Cognition of Nurses.Results:The scores of nurses′ nutritional knowledge, attitude and behavior were (69.70 ± 2.92), (82.76 ± 4.97) and (64.90 ± 4.77) respectively. There were significant differences in nurses′ nutritional knowledge, attitude and behavior at different ages, nursing ages, whether they had children, the highest educational background, department rotation, technical titles, administrative positions, employment methods, article publication, whether they had participated in nutrition training courses and in different regions ( F values were 6.80-60.95, t values were 2.94-7.08, all P<0.05). The main factors affecting nutrition knowledge were region, nursing age, the highest educational background, department rotation and whether they had participated in nutrition training courses ( t values were -6.88-6.73, all P<0.05). The main factors affecting nutritional attitude were region, nursing age and the highest educational background ( t=-2.22, 6.84, 3.21, all P<0.05). The main factor affecting nutritional behavior was nursing age ( t=5.45, P<0.05). Conclusions:Nurses′ nutritional attitude level is excellent, but their mastery of nutritional knowledge and nutritional nursing behavior level need to be improved. Reasonable, scientific and feasible nutritional training courses should be formulated according to the influencing factors of their nutritional knowledge, attitude and behavior, so as to improve nurses′ nutritional knowledge, belief and behavior level and improve the nutritional status and prognosis of hospitalized patients.

Objective:To investigate the risk factors for nonunion after surgery for femoral shaft fractures in order to reduce them.Methods:The clinical data were retrospectively analyzed of the 804 patients with femoral shaft fracture who had been treated from January 2014 to December 2020 at Department of Orthopaedics, Xijing Hospital. There were 575 males and 229 females, aged from 18 to 96 years (average, 43.7 years). The patients were divided into 2 groups according to whether nonunion had occurred after surgery: a nonunion group of 112 cases and a fracture healing group of 692 cases. The preoperative general data, such as age, gender and fracture type, as well as intraoperative and postoperative data, such as operation time, internal fixation method, reduction method and internal fixation failure, were compared between the 2 groups. Items with P<0.05 were included in the multivariate logistic regression analysis to identify the risk factors for nonunion. Results:There were statistically significant differences between the nonunion group and the fracture healing group in smoking history, drinking history, injury mechanism, injury type, multiple injuries, fracture AO classification, fixation method, internal fixation failure, postoperative infection and use of non-steroid anti-inflammtory drugs ( P<0.05). Multivariate logistic regression analysis showed that smoking ( OR=3.261, 95% CI: 2.072 to 5.133, P<0.001), high energy injury ( OR=2.010, 95% CI: 1.085 to 3.722, P=0.026), multiple injuries ( OR=3.354, 95% CI: 1.985 to 5.669, P<0.001), AO type 32-C fracture (type 32-C fracture used as a reference, P=0.034), internal fixation failure ( OR=3.517, 95% CI: 1.806 to 6.849, P<0.001), external stent fixation (external stent fixation used as a reference, P=0.009) were the risk factors for nonunion after femoral shaft fractures. Conclusions:After surgery for patients with femoral shaft fracture, special attention should be paid to those with a smoking habit, high-energy injury, multiple injuries, AO type 32-C fracture, external stent fixation or a failed internal fixation, because they are high-risk groups prone to postoperative nonunion.
