This study was conducted to evaluate the efficacy and safety of Simotang Oral Liquid in the treatment of functional dyspepsia in adults. "Simotang Oral Liquid" "Simotang" "Si Mo Tang" "Si Mo Tang Oral Liquid" were used for retrieval of the relevant papers from CNKI, Wanfang, VIP, SinoMed, PubMed, Cochrane Library, Springer Link, and Web of Science from database inception to June 2021. Randomized controlled trial(RCT) of Simotang Oral Liquid in the treatment of functional dyspepsia in adults was screened out for Meta-analysis which was conducted in RevMan 5.3. A total of 16 RCTs were included. Meta-analysis showed that compared with the control group, Simotang Oral Liquid increased the total response rate and lowered the traditional Chinese medicine syndrome scores, serum cholecystokinin(CCK), serum nitric oxide(NO), and incidence of adverse reactions. However, the serum substance P(SP) had no statistical difference between the two groups. Simotang Oral Liquid is effective and safe in the treatment of functional dyspepsia in adults. However, this study has evidence and limitations, so the conclusions need to be further verified by large sample and multicenter clinical studies.

Aim To investigate the effects of scutellarein on the macrophage foam cell formation and cholesterol efflux, and the underlying mechanism. Methods THP-1 cells were differentiated with PMA, and the cell viability was detected by MTT assays. The effects of scutellarein on the cholesterol efflux and macrophage foam cell formation were evaluated by using NBD-la-beled cholesterol and the cholesterol detection kit. The effects of scutellarein on the activation of PPARγ-LXRα-ABCA1 signaling pathway were determined by molecular docking, ELISA, dual-luciferase reporter and Western blot. The effects of PPARγ knowdown on scutellarein-induced cholesterol efflux and inhibiting macrophage foaming were analyzed by siRNA interference. Results Scutellarein dose-dependently inhibited oxLDL-induced cholesterol accumulation, accelerated cholesterol efflux and significantly increased the protein expression of LXRα and ABCA1. At the same time, scutellarein could bind PPARγ and initiate its downstream LXRa-ABCAl signaling pathway. In addition, gene silencing of PPARγ not only significantly inhibited scutellarein-induced LXRα-ABCA1 signaling pathway and cholesterol efflux, but also reversed the inhibitory effect of scutellarein on macrophage foaming. Conclusions Scutellarein could promote the cholesterol efflux by activating PPARγ and initiating the downstream LXR-ABCA1 signaling pathway, thereby prevent the macrophage foam cell formation.

Aim To determine the effect of FATP5 gene silencing on fatty hepatic cell inflammation and to explore its possible mechanism. Methods Five shR-NA sequences were designed and synthesized. The efficient FATP5-shRNA was screened by the siCHECK™ system. After preparing the FATP5-shRNA lentivirus, the FATP5 gene silence hepatic cell lines was obtained by HepG2 cell infection and puromycin screening. The FATP5 silencing efficiency was detected by Western blot. Then the oleic acid induced ROS and MDA generation, TNF-a and IL-6 protein expression and secretion, and NF-kB activation in FATP5 gene silence cells were analyzed by the detection kit, Western blot, nucleo-plasmic separation and reporter gene system. Results In the gene silence cells, FATP5 protein expression was reduced by 90% and the lipid accumulation was also significantly inhibited. Moreover, the FATP5 knockdown could reduce the oleic acid induced ROS and MDA generation, and suppress the NF-kB activation, thereby inhibiting the protein expression and secretion of TNF-a and IL-6. Conclusions FATP5 gene silence inhibits fatty hepatic cell inflammation, and its mechanism may be related to the inhibition of oxidative stress and lipid peroxidation.

Objective: To understand the knowledge, attitude, and current status of vaccination of herpes zoster vaccination among urban residents aged 25 years and above in China. Methods: In August to October 2022, a convenience sampling method was used to survey residents aged 25 years and above at 36 community centers in 9 cities across China. Questionnaires were used to collect basic information, knowledge, and attitude toward herpes zoster and its vaccination, as well as vaccination status and reasons for non-vaccination among residents. Results: A total of 2 864 urban residents were included in the study. The total score of residents' cognition of herpes zoster and its vaccine was 3.01±2.08, and the total score of their attitude was 18.25±2.76. Factors such as being male (β=-0.45, P<0.001), older than 40-59 years (β=-0.34, P=0.023) or ≥60 years (β=-0.68, P<0.001), married (β=-0.69, P=0.002) were negatively associated with knowledge score. The educational level of high school or secondary school (β=0.44, P=0.036), college (β=0.65, P=0.006), bachelor's degree and above (β=1.20, P<0.001), annual net household income ≥120 000 Yuan in 2021 (β=0.42, P=0.020), having urban employee medical insurance (β=0.62, P=0.030), having public or commercial medical insurance (β=0.65, P=0.033), and having a history of chickenpox (β=0.29, P=0.025) were positively associated with knowledge scores. Being male (β=-0.38, P=0.008) and not remembering a history of chickenpox (β=-0.49, P=0.012) were negatively associated with attitude scores. Annual net household income in 2021 was between 40 000-80 000 Yuan (β=0.44, P=0.032) or between 80 000-120 000 Yuan (β=0.62, P=0.002) or ≥120 000 Yuan (β=0.93, P<0.001), and a history of herpes zoster (β=0.59, P=0.004) were positively associated with attitude scores. Of the 2 864 residents surveyed, only 29 (1.01%) had received the herpes zoster vaccine, with a vaccination rate of 1.70% for those aged 50 years and above, with the main reason for non-vaccination being lack of knowledge about the herpes zoster vaccine, followed by the high price. 42.67% of the population said they would consider getting the herpes zoster vaccine in the future. Conclusion: Low knowledge of herpes zoster and its vaccine, positive attitudes towards the preventive effects of herpes zoster and its vaccine, and extremely low vaccination rates among the urban population in China call for multiple measures to strengthen health education and vaccination recommendations for residents, especially for the elderly, low-education and low-income populations.

Vascular dementia(VD) is a condition of cognitive impairment due to acute and chronic cerebral hypoperfusion. The available therapies for VD mainly focus on mitigating cerebral ischemia, improving cognitive function, and controlling mental behavior. Achievements have been made in the basic and clinical research on the treatment of VD with traditional Chinese medicine(TCM) active components, including Ginkgo leaf extract, puerarin, epimedium, tanshinone, and ginsenoside. Most of these components have anti-inflammatory, anti-apoptotic, anti-oxidant, and neuroprotective effects, and puerarin demonstrates excellent performance in mitigating cholinergic nervous system disorders and improving synaptic plasticity. Puerarin, ginkgetin, and epimedium are all flavonoids, while tanshinone is a diterpenoid. Puerariae Lobatae Radix, pungent in nature, can induce clear Yang to reach the cerebral orifices and has the wind medicine functions of ascending, dispersing, moving, and scurrying. Puerariae Lobatae Radix entering collaterals will dredge blood vessels to promote blood flow, and that entering the sweat pore will open the mind, which is in line with the TCM pathogenesis characteristics of VD. This study reviews the progress in the mechanism of puerarin, the main active component of Puerariae Lobatae Radix, in treating VD. Puerarin can ameliorate cholinergic nervous system disorders, reduce excitotoxicity, anti-inflammation, inhibit apoptosis, alleviate oxidative stress injury, enhance synaptic plasticity, up-regulate neuroprotective factor expression, promote cerebral circulation metabolism, and mitigate Aβ injury. The pathways of action include activating nuclear factor erythroid 2-related factor 2(Nrf2)/antioxidant response element(ARE), vascular endothelial growth factor(VEGF), extracellular regulated protein kinases(ERK), phosphatidylinositol-3-kinase(PI3K)/protein kinase B(Akt), Janus-activating kinase 2(JAK2)/signal transducer and activator of transcription 3(STAT3), AMP-activated protein kinase(AMPK), as well as inhibiting the tumor necrosis factor α(TNF-α), transient receptor potential melastatin 2(TRPM2)/N-methyl-D-aspartate receptor(NMDAR), p38 mitogen-activated protein kinase(p38 MAPK), Toll-like receptor 4(TLR4)/nuclear factor-kappaB(NF-κB), early growth response 1(Egr-1), and matrix metalloproteinase 9(MMP-9). By reviewing the papers about the treatment of VD by puerarin published by CNKI, Wanfang, VIP, PubMed, and Web of Science in the last 10 years, this study aims to support the treatment and drug development for VD.

In order to standardize the clinical diagnosis and treatment decision-making with traditional Chinese medicine for pa-tients of coronavirus disease 2019(COVID-19) and put the latest clinical study evidence into clinical practice, the international trust-worthy traditional Chinese medicine recommendations( TCM Recs) working group started the compilation of Living Evidence-based Guideline for Combination of Traditional Chinese and Western Medicine for Treatment of COVID-19 on the basis of the standards and re-quirements of WHO handbook, GRADE and RIGHT. This proposal mainly introduces the formulation methods and processes of the living guidelines in details, such as the composition of the working group, the collection and identification of clinical issues and out-comes, the production of the living systematic review and the consensus of recommendations. The guidelines will continue to monitor the clinical study evidences of TCM in the prevention and treatment of COVID-19, and conduct regular evidence updating, retrieval and screening. When there is new study evidence, the steering committee will evaluate the possibility of the evidence to change clinical practice or previous recommendations, so as to decide whether the recommendations for the guidelines shall be implemented or upda-ted. The main criteria considered in the guideline updating are as follows:(1) There are new high-quality randomized controlled trial(RCT) evidences for TCM uninvolved in the previous edition of the guidelines;(2) as for the TCM involved in the guidelines, living sys-tematic review shows that new evidence may change the direction or strength of the existing recommendations. The specific implementation of the living evidence-based guidelines will take this proposal as the study basis and framework, in order to ensure the standardization of the formulation process and methods. This will be the first exploration of the methodology for living guidelines in the field of TCM.

Objective:
To recover broad-neutralizing monoclonal antibodies (BnAbs) from avian influenza A (H5N1) virus infection cases and investigate their genetic and functional features.
Methods:
We screened the Abs repertoires of expanded B cells circulating in the peripheral blood of H5N1 patients. The genetic basis, biological functions, and epitopes of the obtained BnAbs were assessed and modeled.
Results:
Two BnAbs, 2-12D5, and 3-37G7.1, were respectively obtained from two human H5N1 cases on days 12 and 21 after disease onset. Both Abs demonstrated cross-neutralizing and Ab-dependent cellular cytotoxicity (ADCC) activity. Albeit derived from distinct Ab lineages, , V 1-69-D2-15-J 4 (2-12D5) and V 1-2-D3-9-J 5 (3-32G7.1), the BnAbs were directed toward CR6261-like epitopes in the HA stem, and HA I45 in the hydrophobic pocket was the critical residue for their binding. Signature motifs for binding with the HA stem, namely, IFY in V 1-69-encoded Abs and LXYFXW in D3-9-encoded Abs, were also observed in 2-12D5 and 3-32G7.1, respectively.
Conclusions
Cross-reactive B cells of different germline origins could be activated and re-circulated by avian influenza virus. The HA stem epitopes targeted by the BnAbs, and the two Ab-encoding genes usage implied the VH1-69 and D3-9 are the ideal candidates triggered by influenza virus for vaccine development.

Objective:
Interferon-induced transmembrane protein 3 (IFITM3) is an important member of the IFITM family. However, the molecular mechanisms underlying its antiviral action have not been completely elucidated. Recent studies on IFITM3, particularly those focused on innate antiviral defense mechanisms, have shown that IFITM3 affects the body's adaptive immune response. The aim of this study was to determine the contribution of IFITM3 proteins to immune control of influenza infection .
Methods:
We performed proteomics, flow cytometry, and immunohistochemistry analysis and used bioinformatics tools to systematically compare and analyze the differences in natural killer (NK) cell numbers, their activation, and their immune function in the lungs of -/- and wild-type mice.
Results:
-/- mice developed more severe inflammation and apoptotic responses compared to wild-type mice. Moreover, the NK cell activation was higher in the lungs of -/- mice during acute influenza infection.
Conclusions
Based on our results, we speculate that the NK cells are more readily activated in the absence of IFITM3, increasing mortality in -/- mice.
