Erchentang is a classic formula widely used by medical practitioners throughout history. In this paper，ancient and modern literature of Erchentang were collected， and bibliometrics was employed to analyze its historic evolution，prescription meaning，herbs origin， processing method，preparation methods， and clinical application. A total of 84 pieces of data were collected， and 58 pieces of data involving 53 ancient medical Chinese books were screened， sorted， and processed. Combined with research of modern scholars，the research has found that the Erchentang originated from the Taiping Huimin Huiye Shijie Fang compiled by the Imperial Medical Bureau of the Song Dynasty. The basic information about the origin of the drugs is quite clear. Pinelliae rhizoma in the formula is the dried tuber of Pinellia ternata. Citri exocarpium rubrum is the dried mature peel of Citrus reticulata and its cultivated varieties， with the inner white membrane removed. Poria is the whitest dry sclerotia of Poria cocos； Glycyrrhizae radix et rhizoma is the dried root and rhizome of the Glycyrrhiza uralensis. The dosage is 5.70 g Pinelliae rhizome and Citri exocarpium rubrum， 3.43 g Poria， and 1.69 g Glycyrrhizae radix et rhizoma praeparata cum melle. During the decoction process， the above-mentioned herbs should be chopped， with 300 mL water， 7 g ginger in thick slices， and 2 g Mume fructus added， and it was then simmered together to 180 mL. After removing the medicinal residue， it can be taken warmly. Erchentang has the effect of drying dampness and resolving phlegm， regulating Qi and harmonizing the middle. It can be used in treating the syndrome of phlegm and dampness，as well as symptoms such as frequent cough，white phlegm，fullness in chest and diaphragm，nausea and vomiting，limb drowsiness，anorexia，dizziness，palpitations，white and greasy tongue coating， and slippery pulse. The above results provide reference for future research and development of Erchentang.

Objective: To explore the setting of gray zone of Treponema pallidum (TP) testing by retrospective analysis of blood donors with single reagent reactive anti-TP results, so as to improve blood utilization and supply safety. Methods: Blood samples were collected from 112 blood donors previously deferred due to single reagent reactive TP antibody results between January 2020 and December 2023, and subjected to dual ELISA reagents and TPPA test. The gray zone panel analysis was performed on the two ELISA reagents currently used in our department. The detection rate at each concentration of the gray zone panle was counted, and the corresponding concentrations for C , C , and C and gray zone cut-off were calculated. Results: Among the 50 samples deferred by reagent 1, 19 were confirmed reactive and 31 non-reactive in supplementary testing. Among the 62 samples deferred by reagent 2, 12 were confirmed reactive and 50 non-reactive in supplementary testing. For reagent 1, the detection rate of was 56% for S/CO≥1 and 20% for 0.5≤S/CO<1, retrospectively. For reagent 2, the detection rate was 27% for S/CO≥1 and 12.5% for 0.5≤S/CO<1, retrospectively. The detection rate for S/CO≥1 was higher than those for 0.5≤S/CO<1 for both reagents. All the 112 samples were negative in TPPA test. The C concentration of reagent 1 was 1.51 mIU/mL, and the concentration range of C ±20% was 1.21-1.81 mIU/mL. The C concentration of reagent 2 was 1.45 mIU/mL, and the concentration range of C ±20% was 1.16-1.74 mIU/mL. The C and C concentration of both reagents were within the C ±20% range, suggesting that the gray zone cutoff for both Reagent 1 and Reagent 2 should be set at S/CO=0.8 (80% of the CO value). Conclusion: All anti-TP single reagent reactive samples with S/CO value within the gray zone was tested negative by TPPA. It is necessary to consider the rationality and necessity of establishing the gray zone, so as to ensure blood safety and improve the utilization rate of blood resources.

Xuanfuhua Decoction （旋覆花汤） is considered as the theoretical prototype of the method of unbloc-king collaterals with acrid and moistened medicinals. Guided by the theories of "chronic disease entering the collaterals" and "collaterals performing their functions when there is free flow"， YE Gui further developed this approach into a systematic method. The core of this approach lies in dispersing and opening constraint with acrid medicinals， nourishing and harmonizing collaterals with moistened medicinals， eliminating pathogens and unblocking collaterals with insect medicinals. The disease course of idiopathic pulmonary fibrosis （IPF） is prolonged， with a complex of deficiency and excess， and chronic disease entering the collaterals. The core pathogenesis involves lung collaterals obstruction， fluid depletion with blood stasis， and chronic disease entering the collaterals. Treatment can be guided by the method of unblocking collaterals with acrid and moistened medicinals based on Xuanfuhua Decoction， following a strategy of "dispersing and unblocking， moistening and nourishing， penetrating and venting". Specifically， for lung collaterals obstruction， acrid medicinals can be used to disperse lung qi and open bi （痹）. In case of fluid depletion and blood stasis， moistened medicinals for nourishing lung collaterals are suggested to restore vitality. For chronic disease ente-ring collaterals， it is advised to search and eliminate collateral pathogens in order to dissipate masses.

In recent decades,the incidence of human papillomavirus(HPV)-associated oropharyngeal squamous cell carcinoma(OPSCC)has shown a marked increase.Significant changes have also occurred in the OPSCC diagnosis and treatment paradigm.Deter-mining HPV status prior to treatment is now essential,and radiotherapy/chemotherapy,immunotherapy,and minimally invasive surgical techniques have progressively emerged as key modalities for managing OPSCC.However,alongside these paradigm shifts,a comprehen-sive technical consensus guiding the entire diagnostic and therapeutic process for OPSCC patients is currently lacking.Given China's large population base and the rising incidence of OPSCC,an expert panel convened to develop a clinical technical consensus on OPSCC diagno-sis and management tailored to China's specific context.This consensus aims to further enhance and standardize understanding of OPSCC management techniques among relevant healthcare professionals.

Salmonella has demonstrated considerable potential as a vaccine vector,exhibiting robust immunogenicity,ease of oral administration,and cost-effective production.Live attenuated Salmo-nella carrying heterologous antigens can induce both localized mucosal immunity and systemic a-daptive immune responses in hosts after successfully reaching the intestinal tract via oral delivery.Recent advances such as permanent deletion of virulence genes,regulated-delayed attenuation and lysis systems,have initially achieved a balance between the safety and immunogenicity of these vaccine platforms.Nevertheless,practical applications of such vaccine vectors remain constrained by challenges related to gastrointestinal barrier obstruction,inefficient antigen delivery,and im-mune tolerance.With the rapid advancement of multidisciplinary technologies,these limitations are anticipated to be progressively addressed.This review presented a comprehensive summary and dis-cussion of the immune mechanisms,development strategies,current applications,advantages,and challenges associated with oral live attenuated Salmonella vaccine vectors.It also delineated the fu-ture direction of research and development,with a view to providing theoretical references for re-lated research.

Objective:To study the risk factors of thyroid nodules in patients with type 2 diabetes.Methods:Data of patients with type 2 diabetes with normal thyroid function admitted to the Department of Endocrinology of Heze Municipal Hospital from January to June 2024 were collected. Binary logistic regression was used to analyze the influencing factors of thyroid nodules in patients with type 2 diabetes, and the receiver operating characteristic curve (ROC curve) was used to evaluate the diagnostic efficacy of each influencing factor.Results:Among 162 patients with type 2 diabetes, 96 had thyroid nodules, accounting for 59.3%. The incidence of thyroid nodules in women was significantly higher than that in men (χ 2 = 4.56, P = 0.034). Multivariate logistic regression analysis showed that age (≥50 years old), overweight and obesity [body mass index (BMI)≥24.0 kg/m 2], high glycated hemoglobin (≥10%), and high total cholesterol ( > 6.5 mmol/L) were independent risk factors for thyroid nodules in patients with type 2 diabetes ( OR = 1.83, 1.67, 1.08, 3.65, P < 0.05), and men was an independent protective factor ( OR = 0.63, P = 0.039). The ROC curve results showed that total cholesterol and total cholesterol combined with glycated hemoglobin could distinguish patients with thyroid nodules from those without thyroid nodules, with AUC = 0.64 and 0.68, respectively, and the differences were statistically significant ( P < 0.05). Conclusions:The incidence of thyroid nodules in patients with type 2 diabetes is relatively high. Age, overweight and obesity, high glycated hemoglobin, and high total cholesterol are independent risk factors for thyroid nodules in patients with type 2 diabetes, and total cholesterol has the ability to distinguish patients with thyroid nodules.

Objective To investigate the predictive value of serum interleukin-17(IL-17)and soluble hemoglobin scavenger receptor 163(sCD163)for early anastomotic leakage in patients with colorectal cancer after laparoscopic surgery.Methods From June 2022 to June 2024,80 colorectal cancer patients who underwent laparoscopic surgery were selected as the study subjects.Patients were subdivided into an anastomotic leakage group(17 cases)and a non-anastomotic leakage group(63 cases)according to whether an anastomotic leakage occurred within 7 d postoperatively.Enzyme-linked immunosorbent assay(ELISA)was applied to detect the levels of serum IL-17 and sCD163 in patients on preoperative day 1,postoperative day 1,postoperative day 3,postoperative day 5,and postoperative day 7.The clinical data of the two groups were compared.Multivariate Logistic regression was applied to analyze the influencing factors of early anastomotic leakage in colorectal cancer patients after laparoscopic surgery.The receiver operating characteristic curve(ROC curve)was applied to analyze the predictive value of serum IL-17 and sCD163 levels for early anastomotic leakage in colorectal cancer patients after laparoscopic surgery.Results The percentage of distance between tumor and anus＜7 cm was higher in the anastomotic leakage group than that in the non-anastomotic leakage group,and the amount of drainage was more than that in the non-anastomotic leakage group at 7 d postoperatively,the differences were statistically significant(P＜0.05).There were statistically significant differences in the levels of serum IL-17 and sCD163 between the two groups of patients at different time points,as well as in time and interaction effects(P＜0.05).Distance between tumor and anus＜7 cm(O R=3.176,95％CI:1.128～8.940),serum IL-17 level ≥ 43.95 pg/mL at 3 d postoperatively(O R=2.145,95％CI:1.281～3.592),and serum sCD163 level ≥ 81.02 pg/mL at 5d postoperatively(OR=1.852,95％CI:1.225～2.801)were the risk factors of early anastomotic leakage in patients with colorectal cancer after laparoscopic surgery(P＜0.05).The area under the curve(AUC)of the combination of serum IL-17 and sCD163 in predicting early anastomotic leakage in colorectal cancer patients after laparoscopic surgery was 0.923,which was superior to the single diagnosis of serum IL-17 and sCD163(Zcombination-IL-17=2.77,Zcombination-sCD163=2.11,P＜0.05).Conclusion Serum IL-17 and sCD163 levels are elevated in colorectal cancer patients with early anastomotic leakage after laparoscopic surgery.The combined detection of the two has certain clinical value in predicting early anastomotic leakage in patients with colorectal cancer after laparoscopic surgery.
