Bacille Calmette-Guérin (BCG) vaccine is designed to provide protection against tuberculosis (TB). However, numerous epidemiological, clinical, and immunological studies have shown that BCG vaccination affects neonatal and infant mortality, which may be related to the reduction of TB-unrelated infections and diseases by BCG vaccine. We aimed to discuss the off-target effects of BCG vaccine on un-TB infections and diseases, as well as the potential mechanism and influencing factors. Literature was retrieved mainly from PubMed using medical subject headings "BCG, variations, and non-specific, heterologous or off-target". Studies have showed that BCG vaccination can prevent various heterologous infections, including respiratory tract infections, leprosy, and malaria, treat viral infections including human papillomavirus and herpes simplex virus infection as immunotherapy, and improve the immune responses as vaccine adjuvant. Besides, BCG vaccine can reduce the recurrence rate of non-muscle-invasive bladder cancer, and may provide protection against autoimmune diseases. These off-target effects of BCG vaccine are thought to be achieved by modulating heterologous lymphocyte responses or inducing trained immunity, which were found to be sex-differentiated and affected by the BCG vaccine strains, sequence or time of vaccination.

Objective:To evaluate the clinical efficacy and safety of ex vivo liver resection and autotransplantation (ELRA) by using a Bayesian single-arm Meta-analysis.Methods:Databases of PubMed, Embase, Cochrane Library, Web of Science, CNKI, and Wanfang were searched from January 1, 1990 to December 30, 2021 on ELRA studies. The Bayesian one-arm Meta-analysis was performed by using the statistical software of R (V4.1.2) and the Markov chain-Monte Carlo method was used to simulate the posterior distribution. The mortality rate within 30 days after operation, 1-year survival rate, major postoperative complications, R 0 resection rate and other related indexes were analyzed. Results:A total of 20 studies with 436 patients were included. Bayesian single-arm Meta-analysis showed that the 1-year survival rate after ELRA was 83.24% [95% highest posterior density ( HPD): 72.40%-92.05%]. The 1-year survival rates after surgery were 88.66% (95% HPD: 81.52%-94.50%) for patients with hepatic alveolar echinococcosis and 61.29% (95% HPD: 38.53%-93.68%) for patients with hepatic malignancies, respectively. The mortality rate within 30 d after surgery, the incidence of significant postoperative complications, and the R 0 resection rate were 6.96% (95% HPD: 4.47%-10.15%), 27.91% (95% HPD: 19.00%-38.30%), and 99.84% (95% HPD: 37.61%-100.00%), respectively. Renal failure was the most frequent cause of death after ELRA. Conclusion:ELRA is indicated for hepatic malignancies and hepatic alveolar echinococcosis when intrahepatic resection cannot be accomplished in vivo. The greatest benefit is observed in patients with hepatic alveolar echinococcosis, while only some patients with hepatic malignancies can benefit. The indications for ELRA for hepatic malignancies need to be further studied to define the subgroup of patients who can benefit from this operation.

Meridian theory plays an important role in the guidance of clinical practice of acupuncture and moxibustion. Since the publication of(), the meridian theory has been developed. In the paper, in view of complex science, the topological properties of acupoint-symptom network were analyzed quantitatively by taking acupoint as node and indication as the connection, such as high clustering coefficient and the small world effect. It was the first time to give the abstraction for the topological proof of the high efficiency information transmission property of acupoint-symptom network meridian system at different times. Its quantitative and digitalized significance was analyzed on the development of meridian theory under the complex scientific background so as to provide a new thought and method for the study of meridian theory and acupuncture modernization.

BACKGROUND:U937 cells can be used as a cell model for studying the biological characteristics,signaling pathways,and therapeutic targets of acute myeloid leukemia.Although it has been reported that long non-coding RNA KIAA0125 is highly expressed in acute myeloid leukemia,its biological function in U937 cells remains unclear,and its mechanism of action in the occurrence and development of acute myeloid leukemia needs to be further clarified. OBJECTIVE:To investigate the expression level of long non-coding RNA KIAA0125 in peripheral blood of patients with acute myeloid leukemia and its effect on the proliferation and apoptosis of U937 cells. METHODS:RNA-sequencing was used to analyze the bone marrow monocyte samples from acute myeloid leukemia patients,and the differentially expressed gene long non-coding RNA KIAA0125 was screened.The expression of long non-coding RNA KIAA0125 in peripheral blood of patients with acute myeloid leukemia was detected by qRT-PCR.The relationship between long non-coding RNA KIAA0125 mRNA expression and prognosis in bone marrow cells of 173 acute myeloid leukemia patients and 70 healthy people was statistically analyzed by GEPIA database.Subsequently,recombinant lentivirus technology and CRISPR/Cas9-SAM technology were used to construct U937 cell lines with knockdown/overexpression of long non-coding RNA KIAA0125.qRT-PCR was used to detect the knockdown/overexpression efficiency of long non-coding RNA KIAA0125.Next,CCK-8 assay,flow cytometry,and western blot assay were used to detect the effects of knockdown/overexpression of long non-coding RNA KIAA0125 on the proliferation and apoptosis of U937 cells.Finally,western blot assay was used to detect the effect of knockdown/overexpressed long non-coding RNA KIAA0125 on Wnt/β-catenin signaling pathway-related proteins. RESULTS AND CONCLUSION:(1)The results of qRT-PCR showed that long non-coding RNA KIAA0125 was highly expressed in peripheral blood of acute myeloid leukemia patients.The results of GEPIA database showed that long non-coding RNA KIAA0125 was highly expressed in bone marrow cells of acute myeloid leukemia patients,and the high expression group had worse overall survival.(2)The knockdown efficiency of long non-coding RNA KIAA0125 in knockdown group was 70%,and the U937 cells that stably down-regulated long non-coding RNA KIAA0125 expression were successfully constructed.The expression of long non-coding RNA KIAA0125 in overexpression group was four times that of vector group,and stable U937 cells were successfully constructed.(3)Knockdown of long non-coding RNA KIAA0125 inhibited the proliferation of U937 cells and promoted their apoptosis.Overexpression of long non-coding RNA KIAA0125 promoted the proliferation of U937 cells but had no significant effect on the apoptosis of U937 cells.(4)Knockdown of long non-coding RNA KIAA0125 inhibited the activity of Wnt/β-catenin signaling pathway,while overexpression of long non-coding RNA KIAA0125 activated Wnt/β-catenin signaling pathway.These results confirm that long non-coding RNA KIAA0125 is highly expressed in acute myeloid leukemia peripheral blood.Long non-coding RNA KIAA0125 may affect the proliferation and apoptosis of U937 cells by regulating the Wnt/β-catenin signaling pathway,and may be a potential prognostic marker for acute myeloid leukemia.

Obesity is a chronic, recurrent, and progressive metabolic disorder characterized by the abnormal or excessive accumulation of body fat caused by multiple factors such as genetics, dietary structure, lifestyle and behavior, psychology, environment, and society, leading to an energy surplus. Obesity is a major risk factor that increases the risk of developing various chronic diseases, including type 2 diabetes, hypertension, cardiovascular diseases, stroke, and certain malignancies. The global incidence of obesity is increasing year by year. With the continuous improvement of people's living standards, more than half of adults in China are now overweight or obese, posing a serious threat to people's health and increasing the social and economic burden. It has become a pressing major public health issue that needs to be addressed urgently. The concept of obesity can be traced back to the Huangdi’s Internal Classic (Huang Di Nei Jing), which describes it as "the problems in fat and affluent people are caused by excessive taking of rich food", and suggests that ''frequent intake of rich and greasy foods can produce interior heat. Sweet flavor causes chest fullness. That is why its spleen-Qi flows upwards and changes into consumption-thirst disease. It can be treated by Eupatorii Herba which is used to remove stagnant Qi''. The stagnant qi is caused by the transformation failure of rich and greasy food and wine, so obesity is the disease of stagnant qi. Obesity is caused by indulging in rich and greasy food, wine, spicy and flavorful foods, raw and cold foods, and sweet and greasy foods, or overeating and leading a sedentary lifestyle, staying up late, or experiencing emotional imbalances such as excessive joy, anger, worry, pensiveness, and fear. It can also be caused by congenital abnormalities, leading to improper functioning of the spleen and stomach, dysregulation of the absorption and secretion of the small intestine, and the accumulation of stagnant Qi in the organs and muscles, resulting in a plump physique. The intake of food and drink depends on the functions of the stomach in receiving and decomposing, the small intestine in absorbing and secreting, and the spleen in transforming and transporting. The affected organs in obesity are the spleen, stomach, and small intestine. Orchids, specifically Eupatorii Herba and Lycopi Herba, are aromatic herbs that can regulate the smooth flow of Qi, eliminate stagnation, and cleanse impurities. In a broader sense, any aromatic and pungent substance that can invigorate the spleen, promote clarity, harmonize the stomach, reduce turbidity, and assist in the normal secretion and absorption functions of the small intestine, thereby eliminating excess, is referred to as orchid. Therefore, the treatment principle for obesity is to use ''orchids to eliminate stagnant Qi'', aiming to regulate the functions of the spleen, stomach, and small intestine using aromatic and pungent substances, gradually eliminating excessive dampness, phlegm, turbidity, and heat, and restore the balance of the middle energizer. This way, individuals who are obese can achieve a non-obese state.
