ObjectiveTo investigate the clinical efficacy and mechanisms of Qigui Didang decoction in the treatment of kidney collateral stasis syndrome in patients with stage Ⅲ-Ⅳ diabetic kidney disease （DKD） in a real-world setting. MethodsPatients with stage Ⅲ-Ⅳ DKD with kidney collateral stasis syndrome admitted to Beijing Aerospace General Hospital from January 2022 to December 2024 were selected for clinical study. According to treatment methods， patients were divided into the Qigui Didang decoction group （Qigui Didang decoction + conventional treatment） and the control group （conventional treatment alone）. A 1∶1 propensity score matching （PSM） method was used to reduce bias caused by confounding factors. Clinical efficacy， traditional Chinese medicine （TCM） symptom scores， renal function indicators， mRNA expression related to pathway mechanisms， glycolipid metabolism indices， and adverse reactions were compared between the two groups. ResultsA total of 120 patients with stage Ⅲ-Ⅳ DKD with kidney collateral stasis syndrome were included， including 62 cases in the Qigui Didang Decoction group and 58 cases in the control group. Before matching， there were statistically significant differences between the two groups in DKD stage， baseline urinary albumin-to-creatinine ratio （UACR）， 24-hour urine total protein （24 h-UTP）， and estimated glomerular filtration rate （eGFR） （P<0.05）. After matching， 47 cases were included in each group， and there was no statistically significant difference in baseline data between the two groups. After matching， the total clinical effective rate of the Qigui Didang decoction group was significantly higher than that of the control group （χ²=4.681， P<0.05）. Compared with data before treatment， the scores of primary and secondary TCM symptoms in the Qigui Didang decoction group were significantly decreased （P<0.05）. Compared with data before treatment， serum creatinine （SCr）， 24 h-UTP， and UACR levels were significantly decreased， while eGFR was significantly increased in the Qigui Didang decoction group （P<0.05）. Compared with data before treatment， the mRNA expression of silent information regulator 1 （Sirt1） was significantly upregulated， while the mRNA expression of nuclear factor-kappa B （NF-κB） and tumor suppressor protein p53 （p53） was significantly downregulated in the Qigui Didang decoction group （P<0.05）. Compared with data before treatment， fasting plasma glucose （FPG）， 2-hour postprandial plasma glucose （2 hPG）， glycated hemoglobin A1c （HbA1c）， total cholesterol （TC）， triglycerides （TG）， and low-density lipoprotein cholesterol （LDL-C） levels were decreased， while high-density lipoprotein cholesterol （HDL-C） levels were increased （P<0.05）. There was no statistically significant difference in adverse reactions between the two groups. ConclusionQigui Didang decoction combined with conventional treatment can significantly improve renal function， glycolipid metabolism， and TCM syndromes in patients with stage Ⅲ-Ⅳ DKD with kidney collateral stasis syndrome， with good safety. The mechanism may be related to the regulation of the Sirt1/NF-κB/p53 signaling pathway.

With the rising incidence of diabetes， diabetic kidney disease （DKD） has become a significant global health burden. Although current prevention and treatment strategies can partially delay the progression of DKD， the risk of patients advancing to end-stage renal disease remains high. Since the concept of the "gut-kidney axis" was first introduced at the International Congress on Dialysis in 2011， research on the role of gut microbiota in the pathogenesis of DKD has received increasing attention. This review summarizes the current research on gut microbiota， explores the mechanisms through which it contributes to DKD development， and outlines clinical approaches for DKD prevention and treatment based on the "gut-kidney axis" theory. Evidence indicates that dietary interventions， intake of probiotics or prebiotics， use of metformin and novel antidiabetic drugs， and application of traditional Chinese medicine （TCM） compound formulas can effectively improve gut microbiota composition， influence metabolite production， and restore the intestinal mucosal barrier. These interventions can further regulate intestinal innate immunity and inflammatory responses， thereby modulating the progression of DKD. Despite challenges posed by the traditional oral administration of water-decocted TCM compound formulas and the complexity of their ingredients， increasing evidence suggests that TCM may indirectly affect the occurrence and development of DKD by modulating gut microbiota. This finding provides a new perspective on the potential mechanisms of TCM in DKD treatment and may offer novel strategies for DKD prevention and therapy.

Traditional Chinese medicine （TCM） offers a rich theoretical foundation and clinical experience for the prevention and treatment of cardiovascular-kidney-metabolic syndrome（CKM）， demonstrating unique advantage. Building on previous work in managing diabetes， its complications， and chronic kidney disease， our team has proposed a five-phase evolution theory of "constraint， heat， deficiency， stasis， and toxin" as the core pathogenesis. These phases correspond to the pathological progression of constraint of phlegm-dampness， constraint transforming into heat， heat damaging qi and yin， stasis accumulated in the collateral vessels， and toxin induced by deficiency and stasis. In the prevention and treatment of CKM by TCM， it is emphasized to integrate the concept of "treating disease before it arises" with constitution theory， and incorporate the "2-5-8" prevention and treatment strategy， which combines prevention with treatment， tailors interventions to different phases， and employs comprehensive treatment modalities. Our goal is to leverage TCM's holistic advantages in preventing and treating CKM.

G protein-coupled receptors (GPCRs) are a large family of membrane protein receptors, and Takeda G protein-coupled receptor 5 (TGR5) is a member of this family. As a membrane receptor, TGR5 is widely distributed in different parts of the human body and plays a vital role in regulating metabolism, including the processes of energy consumption, weight loss and blood glucose homeostasis. Recent studies have shown that TGR5 plays an important role in glucose and lipid metabolism disorders such as fatty liver, obesity and diabetes. With the global obesity situation becoming more and more serious, a comprehensive explanation of the mechanism of TGR5 and filling the gaps in knowledge concerning clinical ligand drugs are urgently needed. In this review, we mainly explain the anti-obesity mechanism of TGR5 to promote the further study of this target, and show the electron microscope structure of TGR5 and review recent studies on TGR5 ligands to illustrate the specific binding between TGR5 receptor binding sites and ligands, which can effectively provide new ideas for ligand research and promote drug research.

African swine fever virus(ASFV)I177L gene deletion vaccine is one of the key directions of African swine fever(ASF)live attenuated vaccine research and development.In order to effec-tively distinguish between the wild-type ASFV strain and the I177L gene-deleted strain,specific primers and probes were designed based on ASFV B646L and I177L genes,respectively.After screening and optimization,a duplex real-time PCR method was developed that can simultaneously detect these two genes.The results showed that ASFV B646L and I177L genes were detected spe-cifically and simultaneously by the method developed without cross-reactions with porcine circovir-us type 2,Seneca virus A,classical swine fever virus,foot-and-mouth disease virus,porcine respira-tory and reproductive syndrome virus.The detection limits of the duplex real-time PCR for recom-binant plasmids pUC57-B646L and pUC57-I177L were 1×103 copies/mL.The intra-and inter-as-say coefficients of variation were less than 4％,respectively.Detection of 122 pork and pork prod-ucts using the duplex real-time PCR developed and the real-time PCR recommended by WOAH showed that the coincidence rates of the two methods for B646L gene detection was 100％with two amplification curves appeared in the positive results of the established methods.The method established in this study can be used for the detection of ASFV I177L gene deletion strains,which provides technical support for ASF surveillance and epidemiological investigation.

Objective:To investigate the effects of allogeneic hematopoietic stem cell transplantation (allo-HSCT) in treatment of high-risk multiple myeloma (MM) patients and its influencing factors of the prognosis.Methods:The clinical data of 44 high-risk MM patients treated with allo-HSCT in Changzheng Hospital Affiliated of Naval Military Medical University from April 2003 to March 2017 were retrospectively analyzed. The overall response rate (ORR), relapse rate, non-relapse-related death (NRM) rate, graft-versus-host disease (GVHD) incidence of patients were also analyzed. Kaplan-Meier was used to analyze the overall survival (OS) rate and progression-free survival (PFS) rate after transplantation. Cox proportional hazard model was used to make regression analysis of the factors affecting the prognosis.Results:Among 44 patients, 38 cases could be evaluated for efficacy after transplantation. The median follow-up time was 111 months (0-216) months, 22 cases survived, 22 cases died, 21 cases relapsed. Before transplantation, complete remission (CR) rate was 29.5%(13/44), very good partial remission(VGPR) rate was 45.5%(20/44), partial remission (PR) rate was 22.7% (10/44), stable disease (SD) rate was 2.3% (1/44); After transplantation, CR rate was 71.7%(27/38), VGPR rate was 13.2% (5/38), PR rate was 13.2% (5/38), the progression of the disease (PD) rate 2.6% (1/38). The 5-year OS rate and PFS rate was 51.8% and 47.8%, the 10-year OS rate and PFS rate was 51.3% and 43.1%, respectively; the 5-year and 10-year cumulative disease relapse rate was 38.6% and 45.4%, the 5-year cumulative NRM rate was 25.0%. Acute GVHD rate was 38.6% (17/44) and grade 3-4 acute GVHD rate was 6.8% (3/44); chronic GVHD rate was 27.3% (12/44). Cox univariate and multivariate analysis showed that the use of bortezomib before transplantation ( HR = 3.461, 95% CI 1.211-9.880, P = 0.020) and post-transplant infection ( HR = 0.283, 95% CI 0.098-0.819, P = 0.020) were independent factors affecting OS after transplantation. Conclusions:Allo-HSCT can overcome the high-risk factors of MM and is worth to try for high-risk MM patients. The use of bortezomib before transplantation and post-transplant infection can be important factors affecting OS after transplantation.

Objective:To investigate the treatment options for multiple myeloma patients with central nervous system involvement (CNS-MM) , as well as their clinical characteristics and prognostic factors.Methods:Between January 2011 and January 2022 our center diagnosed 18 people with CNS-MM. A retrospective analysis was done on the clinical information from the initial diagnosis and central nervous system involvement, and it was compared to 1∶3 matched newly diagnosed MM from the same period. Analysis was done on the clinical characteristics and survival rates of the two groups.Results:In patients with CNS-MM, the median time of onset was 14.2 (0.9-79.6) months and the median overall survival (OS) was 30.5 months from initial diagnosis and only 3.8 months in patients after CNS involvement. The CNS-MM patients showed more IgD type ( P=0.010) , severer anemia ( P=0.014) , a higher proportion of bone marrow plasma cells ( P=0.013) , more extramedullary lesions ( P=0.001) , and increased lactic dehydrogenase (LDH) ( P=0.009) when compared to the control group. Lenalidomide or pomalidomide-based combinations had higher rates of hematology and CNS remission than bortezomib or daratumumab-based regimens (75.0% vs 16.7% , P=0.019) . Patients who received IMiD-based regimens and had 2 high-risk factors at initial diagnosis (high LDH and extramedullary lesions) had a significantly lower incidence of CNS-MM ( P=0.026) . At the initial diagnosis, LDH ( P=0.008, HR=7.319, 95% CI 1.663-32.219) and extramedullary lesions ( P=0.006, HR=8.054, 95% CI 1.828-35.486) were independent risk factors for the occurrence of CNS-MM. Conclusion:Patients with CNS-MM had a poor prognosis. Patients with high LDH or extramedullary lesions at the time of the initial diagnosis are more likely to have CNS-MM. The prognosis of this patient may be improved by immunoregulator-based therapy.

Objective:To investigate the efficacy and safety of daratumumab in relapsed and refractory multiple myeloma (RRMM) .Methods:The clinical characteristics, adverse reactions, efficacy, and prognosis of 46 patients with RRMM treated with daratumumab in Shanghai Changzheng Hospital from September 2017 to March 2020 were retrospectively analyzed.Results:All patients were treated with daratumumab-based regimen: 8 in the Dd group, 35 in the DRd group, and 3 in the DVd group. With a median follow-up of 9.6 months, the overall response rate (ORR) was 75% [complete remission (CR) rate 18.2% ] among the 44 patients available for evaluation. The ORRs of patients resistant to bortezomib, lenalidomide, and both were 70.6% , 69.2% , and 63.6% , respectively. The CR rates of patients resistant to bortezomib, lenalidomide, and both were 17.6% , 11.5% , and 13.6% , respectively. No significant difference was observed in ORR and CR rates among the three groups. The ORRs of the DRd, DVd, and Dd groups were 85.3% , 66.7% , and 28.6% , respectively ( P=0.007) . The median PFS of 46 patients was 8.9 months, the median OS was not reached, and the 1-year OS rate was 74% . The median PFS and OS in the DRd group were longer than those in the Dd group (PFS: 14.4 months vs 2.0 months; OS: not reached vs 5.2 months) . After treatment with daratumumab, neutropenia is the most common hematological adverse reaction above grade 3. Non-hematological adverse reactions are mainly infusion-related adverse reactions and infections. Prognostic analysis showed that patients with extramedullary invasion had shorter PFS and OS compard with patients without extramedullary invasion (PFS: 5.7 vs 14.4 months, P=0.033; OS: 6.3 months vs not reached, P=0.029) . The OS of patients with an ECOG score of 3-4 was significantly shorter than patients with an ECOG score of 1-2 (5.9 months vs not reached, P=0.004) . Conclusion:Daratumumab-based regimens have good efficacy and safety in the treatment of RRMM.

Objective:To summarize the clinical characteristics and prognosis of 51 patients with Waldenstr?m’s macroglobulinemia (WM) and evaluate the efficacy and adverse reactions of ibrutinib in the treatment of WM.Methods:We carried out a single-center retrospective study, including 51 patients with WM of our single center from November 2008 to October 2019.Results:The median age at diagnosis was 65 years with a male-to-female ratio of 2.64∶1. There were 9 (18%) , 21 (41%) , and 21 (41%) ISSWM stage low-, intermediate- and high-risk patients identified, respectively. A total of 27 (73%) patients harbored MYD88 L265P mutation. The median follow-up time was 38.6 (0.3-120.0) months, the median progression free survival was 46.4 months, and the median overall survival was not reached. The overall remission and major remission rates of patients who received ibrutinib were 87% and 80%, respectively. The median time to achieve at least partial remission of patients treated with ibrutinib was 8 weeks, which was earlier than those treated with other drugs ( P<0.05) . Conclusion:WM is often seen in elderly men. MYD88 L265P had a high frequency in WM. The findings of our study validate the efficacy of ibrutinib monotherapy. Even in patients with advanced age and at high risk of ISSWM, the overall remission rate and major remission rate are high. Ibrutinib is a safe and effective therapy because of its rapid onset and rare serious adverse reactions.
