Systemic lupus erythematosus (SLE) is an autoimmune disease accompanied by various complications, and the exact etiology remains unclear. Treatments for SLE encompass hormone therapy, plasma exchange and immunoadsorption, and targeted biological therapies. Berbamine (BBM), a cellular immunopotentiator with diverse biological functions, has not been reported to have immunomodulatory and therapeutic effects on SLE. The mice were divided into control group, model group, positive control group, low, medium and high BBM groups. In control group, C57BL/6J wild mice received intraperitoneal injection of saline. In model group, MRL/lpr lupus mice were treated with intraperitoneal injection of saline. In positive control group, MRL/lpr lupus mice received intragastric administration of hydroxychloroquine sulfate tablets [Plaquenil, 150 mg/(kg·d)]. In BBM groups, MRL/lpr lupus mice received intragastric administration of different concentration of BBM respectively [20 mg/(kg·d), 50 mg/(kg·d), 100 mg/(kg·d)]. After 8 weeks of treatment, blood was collected from the retro-orbital venous plexus, and ELISA was used to detect the levels of anti-double-stranded DNA (dsDNA) antibodies, antinuclear antibodies (ANA), and anti-small nuclear ribonucleoprotein/Sm (snRNP/Sm) antibodies. Spleen tissues were collected for analysis of Th1/Th2 ratio by flow cytometry. The RNA and protein of spleen were extracted, and the levels of T-box transcription factor T-bet and GATA3 (GATA binding protein 3) mRNA and protein were detected by qRT-PCR and Western blot. The proliferation of white blood cells in the blood was tested by blood routine test. The histopathological changes of kidneys of each group were detected by HE staining. Compared with the model group, the levels of ANA, anti-dsDNA, and anti-snRNP/Sm antibodies were significantly reduced in the BBM-treated groups. The Th1/Th2 ratio was significantly decreased in the model group, but reversed by BBM. Compared with the control group, T-bet expression was significantly downregulated, while GATA3 expression was significantly upregulated in the model group. After BBM intervention, T-bet expression significantly increased, while GATA3 expression decreased compared with the model group. The number of white blood cells significantly decreased in the model group, and increased in the BBM-treated groups. In the model group, the glomerular mesangial and endothelial cells showed significant hyperplasia, clear thrombus was observed in the dilated capillaries, and inflammatory cells infiltrated in the renal interstitium. In medium and high BBM groups, the infiltration of inflammatory cells and capillary thrombosis were significantly decreased. In conclusion, BBM exhibits certain immunomodulatory effects on SLE and promotes the proliferation of white blood cells.

Hypertension is a major risk factor for cardiovascular diseases. Controlling blood pressure can reduce the incidence of cardiovascular events and mortality. The patients with hypertension are mainly treated with antihypertensive drugs. For the patients who can't achieve the target blood pressure with a single drug, comprehensive treatment strategies become particularly important. Chinese patent medicines are prepared by modern extraction and processing technology based on the basic theory of traditional Chinese medicine(TCM). Due to the stable antihypertensive effect, target organ protection, and synergistic effect with western medicine, Chinese patent medicines are becoming one of the effective options for the treatment of hypertension. At present, there are many systematic reviews on the treatment of hypertension with Chinese patent medicines, which makes it difficult for health policy makers and health service providers to choose the best evidence for the treatment. Umbrella review can integrate multiple systematic reviews to comprehensively assess the quality of evidence and potential bias, thereby providing high-quality evidence-based medicine basis for formulating clinical guidelines and optimizing treatment strategies. In this study, the systematic reviews/Meta-analysis of Chinese patent medicines in the treatment of essential hypertension were systematically searched. Sixty-nine articles were included for the umbrella review. Literature information was extracted, and the corrected covered area(CCA) was calculated to quantitatively evaluate the overlap degree of original studies in systematic reviews/Meta-analysis. The risk of bias in systematic reviews(ROBIS) tool and Cochrane RoB tool 2.0 were used to assess the risk of bias of the included studies. A Measure Tool to Assess Systematic Reviews 2(AMSTAR 2) was used to evaluate the methodological quality of systematic reviews/Meta-analysis. The quality of evidence was evaluated based on the Grade of Recommendations Assessment, Development and Evaluation(GRADE). The results showed that the Chinese patent medicines in the categories of treating wind, resolving stasis, and reinforcing healthy Qi were effective in lowering blood pressure. The Chinese patent medicines for resolving stasis combined with conventional treatment can lower blood pressure and the levels of low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, triglyceride, and total cholesterol in the treatment of hypertension complicated with coronary heart disease and hypertension complicated with left ventricular hypertrophy. Moreover, the combined therapy can recover the interventricular septal thickness, left ventricular posterior wall thickness, left ventricular mass index, left ventricular end diastolic diameter, and left ventricular ejection fraction in the case of left ventricular hypertrophy. The Chinese patent medicines for resolving stasis and for replenishing Qi and restoring pulse can be used in combination with conventional treatment for hypertension complicated with arrhythmia, which can lower blood pressure while improving the outcome indicators such as the P-wave dispersion of arrhythmia, left atrial diameter, ejection fraction, heart rate, and recurrence time. Due to the heterogeneity, the efficacy evidence obtained by the umbrella review needs to be further verified through precise clinical studies and long-term follow-up.

OBJECTIVE:
To screen anti-tumor drugs that improve antigen processing and presentation in acute myeloid leukemia (AML) cells.
METHODS:
A TCR-like or TCR mimic antibody that can specifically recognize HLA-A*0201:WT1126-134 ( RMFPNAPYL) complex (hereafter referred to as HLA-A2:WT1) was synthesized to evaluate the function of antigen processing and presentation machinery (APM) in AML cells. AML cell line THP1 was incubated with increasing concentrations of IFN-γ, hypomethylating agents (HMA), immunomodulatory drugs (IMiD), proteasome inhibitors (PI) and γ-secretase inhibitors (GSI), followed by measuring of HLA-ABC, HLA-A2 and HLA-A2:WT1 levels by flow cytometry at consecutive time points.
RESULTS:
The TCR-like antibody we generated only binds to HLA-A*0201+WT1+ cells, indicating the specificity of the antibody. HLA-A2:WT1 level of THP-1 cells detected with the TCR-like antibody was increased significantly after co-incubation with IFN-γ, showing that the HLA-A2:WT1 TCR like antibody could evaluate the function of APM. Among the anti-tumor agents screened in this study, GSI (LY-411575) and HMA (decitabine and azacitidine) could significantly increase the HLA-A2:WT1 level. The IMiD lenalidomide and pomalidomide could aslo upregulate the expression of HLA-A2:WT1 complex under certain concentrations of the drugs and incubation time. As proteasome inhibitors, carfilzomib could significantly decreased the expression of HLA-A2:WT1, while bortezomib had no significant effect on HLA-A2:WT1 expression.
CONCLUSION
HLA-A2:WT1 TCR-like antibody can effectively reflect the APM function. Some of the anti-tumor drugs can affect the APM function and immunogenicity of tumor cells.

OBJECTIVE:
To analyze the Epstein-Barr virus (EBV) load in different lymphocyte subsets, as well as clinical characteristics and outcomes in patients with hematologic malignancies experiencing EBV reactivation.
METHODS:
Peripheral blood samples from patients were collected. B, T, and NK cells were isolated sorting with magnetic beads by flow cytometry. The EBV load in each subset was quantitated by real-time quantitative polymerase chain reaction (RT-qPCR). Clinical data were colleted from electronic medical records. Survival status was followed up through outpatient visits and telephone calls. Statistical analyses were performed using SPSS 25.0.
RESULTS:
A total of 39 patients with hematologic malignancies were included, among whom 35 patients had undergone allogeneic hematopoietic stem cell transplantation (allo-HSCT). The median time to EBV reactivation was 4.8 months (range: 1.7-57.1 months) after allo-HSCT. EBV was detected in B, T, and NK cells in 20 patients, in B and T cells in 11 patients, and only in B cells in 4 patients. In the 35 patients, the median EBV load in B cells was 2.19×104 copies/ml, significantly higher than that in T cells (4.00×103 copies/ml, P <0.01) and NK cells (2.85×102 copies/ml, P <0.01). Rituximab (RTX) was administered for 32 patients, resulting in EBV negativity in 32 patients with a median time of 8 days (range: 2-39 days). Post-treatment analysis of 13 patients showed EBV were all negative in B, T, and NK cells. In the four non-transplant patients, the median time to EBV reactivation was 35 days (range: 1-328 days) after diagnosis of the primary disease. EBV was detected in one or two subsets of B, T, or NK cells, but not simultaneously in all three subsets. These patients received a combination chemotherapy targeting at the primary disease, with 3 patients achieving EBV negativity, and the median time to be negative was 40 days (range: 13-75 days).
CONCLUSION
In hematologic malignancy patients after allo-HSCT, EBV reactivation commonly involves B, T, and NK cells, with a significantly higher viral load in B cells compared to T and NK cells. Rituximab is effective for EBV clearance. In non-transplant patients, EBV reactivation is restricted to one or two lymphocyte subsets, and clearance is slower, highlighting the need for prompt anti-tumor therapy.

OBJECTIVE:
To explore the effects of electroacupuncture (EA) on pregnancy outcomes after assisted reproduction and mitochondrial function of granulosa cells (GCs) in patients with polycystic ovary syndrome (PCOS) and phlegm-dampness syndrome.
METHODS:
In this randomized controlled trial, 90 infertile women with PCOS and phlegm-dampness syndrome were recruited between August 2022 and December 2022. Patients were randomly assigned to the EA and control groups using a random sequence of codes in the order of enrolment, with 45 in in each group. Both groups underwent the ovarian stimulation protocol. The patients in the EA group received EA therapy including Zhongwan (CV 12), Qihai (CV 6), bilateral Xuehai (SP 10), Sanyinjiao (SP 6), Yinlingquan (SP 9), Tianshu (ST 25), Zusanli (ST 36), and Fenglong (ST 40), and the patients in the control group was treated with pseudo-acupuncture. The intervention was 25 min twice a week for a total of 6 times until the trigger day after menstruation had ended in the cycle before oocyte retrieval. The primary outcomes were clinical pregnancy rate (CPR) and the number of high-quality embryos. The secondary outcomes were (1) pregnancy-related indicators, including fresh embryo transfer rate (ETR), ovarian hyperstimulation syndrome (OHSS) rate, early pregnancy loss rate (ePLR), ectopic pregnancy rate, live birth rate (LBR), and cumulative CPR; (2) mitochondrial autophagy and mitochondrial membrane potential (MMP) in GCs; and (3) scoring for Chinese medicine syndrome. Adverse events to assess clinical safety were also monitored.
RESULTS:
The cumulative CPR was significantly higher in the EA group (42/45, 93.3%) than in the control group (38/45, 84.4%, P=0.036). The number of high-quality embryos and fresh ETR in the EA group were higher than those in the control group (3.80±1.65 vs. 2.44±1.34, P<0.001; 46.7% vs 24.4%, P=0.028). Ectopic pregnancies were not observed in either group. There were no significant differences in the fresh CPR, OHSS rate, ePLR or LBR between the two groups (P>0.05). Compared with the control group, the EA group showed lower expression levels of miR-146a-5p mRNA and P62 protein in GCs and higher levels of MMP and the LC3-II/LC3-I protein ratio (all P<0.01). The phlegm-dampness syndrome scores of the EA group were significantly lower than those of the control group (P<0.01).
CONCLUSIONS
EA significantly improved pregnancy outcomes in patients with PCOS and phlegm dampness syndrome. Mechanistically, this effect may be related to EA in decreasing miR-146a-5p mRNA expression, promoting mitochondrial autophagy in GCs, and improving mitochondrial function, which may contribute to improved oocyte quality.

Objective To explore the regulatory role of Abelson interactor 2(ABI2)in progression and prognosis of gastric cancer.Methods TIMER2.0,GEPIA,Kaplan-Meier Plotter and DAVID databases were used to analyze ABI2 expression in pan-cancer and its association with the prognosis of gastric cancer.Gastric cancer and adjacent tissues from 120 patients undergoing radical gastrectomy in our hospital between January,2016 and October,2018 were examined for ABI2 expression and its correlation with disease progression and prognosis.MGC-803 cell models of ABI2 knockdown and overexpression were established for observing the changes in cell proliferation,migration,and invasion,and the impact of ABI2 expression modulation on xenograft growth was evaluated in nude mice.Results Database analysis and examination of the clinical samples showed that ABI2 was highly expressed in gastric cancer tissues.Survival analysis suggested that gastric cancer patients with a high expression of ABI2 had a reduced postoperative 5-year survival rate(P<0.0001),and further Cox univariate and multivariate survival analyses indicated that a high ABI2 expression was an independent risk factor affecting the patients survival outcomes(P=0.022,HR=1.887,95%CI:1.096-3.249).Enrichment analysis suggested the involvement of ABI2 in Wnt signaling.In MGC-803 cells,ABI2 overexpression promoted cell proliferation and xenograft growth in nude mice,increased the expressions of vimentin and N-cadherin,and lowered E-cadherin expression,while ABI2 knockdown produced the opposite effects.Mechanistic analysis revealed that ABI2 overexpression promoted the expressions of Wnt2 and β-catenin in both MGC-803 cells and the xenografts,and their expressions were significantly lowered by ABI2 knockdown.Conclusion ABI2 is highly expressed in gastric cancer,which affects long-term prognosis of the patients,possible due to its regulatory effect on Wnt signaling to promote proliferation,migration and invasion of gastric cancer cells.
