Effect of Shuanghuanglian Oral Solution on Liver Function in a Mouse Model of Non-alcoholic Steatohepatitis

[Objectives]To observe the effect of Shuanghuanglian oral solution on liver function in BABL/cJ mice in non-alcoholic steatohepatitis(NASH)model.[Methods]The BABL/cJ mice were randomly divided into three groups:a control group,a model group,and an experimental group.The experimental group was administered with 10%Shuanghuanglian oral solution at a dose of 0.1 mL/(10 g·d),while the control group and experimental group received an equivalent dosage of normal saline.All three groups were treated for a period of 28 d.The liver function of the mice in each group was examined after the treatment.[Results]The body mass,liver index,triacylglycerol(TG),total cholesterol(TC),aspartate aminotransferase(AST),and alanine aminotransferase(ALT)levels were all significantly reduced compared to the model group(P<0.05).[Conclusions]Shuanghuanglian oral solution has a beneficial effect on liver function in BABL/cJ mice.

Rapid and Sensitive Assay of the Main Components in Shuanghuanglian Preparations by UPLC-TOF-MS

1 Introduction As already known, complex prescription has been the outstanding feature of traditional Chinese medicine（TCM）. This fact therefore brings complicated formula with multicomponents from multimaterals, which produces some difficulties to detect the components and to control the quality. Shuanghuanglian preparations（SHLs）, including oral liquid, injection powder, capsule, and tablet, belong to a family of refined traditional Chinese patent medicine and a combined herbal remedy comprised of three herbs：

Inhibitory effects of Shuanghuanglian injection on nuclear factor-kappa B expression in mice with viral encephalitis in a time-and dose-dependent manner

Previous studies have confirmed that the anti-virus effects of Shuanghuanglian injection may be associated with nuclear factor-kappa B activity. This study observed nuclear factor-kappa B expression in mice with viral encephalitis, and showed significant decreases in nuclear factor-kappa B protein and mRNA levels following Shuanghuanglian injection. The inhibitory effect was more significant with prolonged intervention duration and increased treatment dose. These findings verify that Shuanghuanglian injection plays a therapeutic role in viral encephalitis by reducing expression of nuclear factor-kappa B in a time- and dose-dependent manner.

Outlining the keyword co-occurrence trends in Shuanghuanglian injection research: A bibliometric study using CiteSpace Ⅲ

Objective:To explore the evolvement and new trends in the use of Shuanghuanglian injection(SHLI).Methods:China National Knowledge Infrastructure(CNKI),PubMed,and Embase were extensively searched using the search terms“Shuanghuanglian injection”and“Shuanghuanglian fenzhen”to retrieve articles relevant to SHLI(1992e2020).Retrieved articles were further investigated by two authors to exclude those unrelated to SHLI.The bibliographical references of the included articles were exported as raw data and then treated using the CiteSpace tool to visualize the mapping of the SHLI research domain.Essential clusters and highly frequent keywords were quantified for further analysis.The clusters were automatically labeled by the algorithm of tf*idf for objective analysis.Basic bibliometric features,including article types and yearly trend in article numbers were also determined and discussed.Results:The modules of the keywords of interest presented clear boundaries with a high modularity score(Q=0.73).High-confidence clusters were identified,including bioactivity fingerprint(S=0.99),equal pupils(S=0.91),drug preparation department(S=0.87),difficulty in respiration(S=0.85),peristalsis(0.88),and Danshen powder injection(S=0.94).The characteristic keywords in terms of frequency and burstiness were Shuanghuanglian powder for injection(F=235,B=5.22),SHLI(F=112,B=11.39),and adverse drug reactions(ADRs;F=104,B=7.35).Conclusion:In the field of SHLI study,there are five major topic categories:bioactivity fingerprint;ADR mechanism and cause detection;proper preparation;clinical evidence accumulation;and efficacy in diseases with no effective treatment and combination usage.The trend for using modern methodologies from a science-based perspective to study SHLI will continue to exist.The causes of multi-factorial ADRs may be an important topic for future studies.

Shuanghuanglian injection downregulates nuclear factor-kappa B expression in mice with viral encephalitis

A mouse model of viral encephalitis was induced by intracranial injection of a Coxsackie virus B3 suspension. Quantitative real-time reverse transcription-PCR and western blot assay were applied to detect mRNA and protein expression of intelectin-2 and nuclear factor-kappa B in the viral encephalitis and control groups. Nuclear factor-kappa B and intelectin-2 mRNA and protein expression were significantly increased in mice with viral encephalitis. After intraperitoneal injection of Shuanghuanglian at a dose of 1.5 mg/kg for 5 successive days, intelectin-2 and nuclear factor-kappa B protein and mRNA expression were significantly decreased. To elucidate the relationship between intelectin-2 and nuclear factor-kappa B, mice with viral encephalitis were administered an intracerebral injection of 107 pfu recombinant lentivirus expressing intelectin shRNA. Both protein and mRNA levels of intelectin and nuclear factor-kappa B in brain tissue of mice were significantly decreased. Experimental findings suggest that Shuanghuanglian injection may downregulate nuclear factor-kappa B production via suppression of intelectin production, thus inhibiting inflammation associated with viral encephalitis.

Effects of Shuanghuanglian Propolis Oral Liquid on Growth Performance and Intestinal Microflora of Broilers

[ Objective] The paper was to investigate the effects of adding different levels of Shuanghuanglian propelis oral liquid in drinking water on growth performance and intestinal microflora of broilers. [ Method] Ninety one-day-old broilers were randomly divided into three groups （group I, group 1I and group III）： group I was the control group, and groups II and III were added with 0.5 and 1.0 mL/L Shuanghuanglian prepolis oral liquid in drinking water, respec- tively. [ Result] Compared with broilers in group I, the average daily gains of broilers in group II and group III increased significantly （ P 〈 0.05 ） ; the feed gain ratio of broilers in group III was significandy lower than that in group I （ P 〈 0.05 ） ; the number of intestinal LactobaciUus spp. in group II and group III in- creased significantly （ P 〈 0.05 ） ; the number of Salmonella spp. and Escherichia coli in group lII decreased significantly （ P 〈 0.05 ） ; the number of Bgrdobacterium spp. increased significantly （ P 〈 0.05 ）. [ Conclusion] Adding 0.5 and 1.0 mL/L Shuanghuanglian propolis oral liquid in drinking water could improve growth performance and intestinal micreflora of broilers, and the dose of 1.0 mL/L is recommended in clinical application.
