Effectiveness and safety of Chaihu-Shugan-San for treating depression based on clinical cases: An updated systematic review and meta-analysis.

BACKGROUND: Chaihu-Shugan-San (CSS), a Traditional Chinese Medicine formula, has been widely used for treating depression since the Ming Dynasty, as recorded in Jingyue Quanshu, but its effectiveness and safety lack comprehensive and objective evaluation. Based on our meta-analysis, we aimed to adequately evaluate the efficacy and risk of CSS by considering the latest clinical literature. METHODS: Multiple databases, including PubMed, Embase, Web of Science, SinoMed, China National Knowledge Infrastructure, Chongqing VIP, and Wanfang, were used to collect clinical data. The quality of the included clinical studies was assessed using the Cochrane Risk of Bias Tool, and the data were meta-analyzed using Review Manager 5.0 and Stata 17. The data were obtained from a genome-wide association study, and Mendelian randomization (MR) was performed using R Software 4.3.2 with the TwoSampleMR and MR Pleiotropy RESidual Sum and Outlier packages. RESULTS: A total of 15 studies with 1034 patients and 6 antidepressant drugs were included in this work. Meta-analyses revealed that drug combinations of CSS and antidepressants significantly improved depressive symptoms (weighted mean difference = -4.21; 95% confidence interval [CI]: -5.62--2.81), increased the effective rate (odds ratio [OR] = 3.82; 95% CI: 2.44-6.83), and reduced side effects (OR = -3.55; 95% CI: -5.66--1.43) compared with antidepressant monotherapy. Additionally, compared with antidepressant monotherapy, CSS alone exhibited fewer side effects (95% CI:-9.25--6.95). Like antidepressants, CSS also improved depressive symptoms (weighted mean difference = -0.05; 95% CI: -0.63--0.52) and increased the effective rate (OR = 1.07; 95% CI: 0.52-2.20). Additionally, MR was used to evaluate the safety of traditional antidepressants, as there was a causal association between amitriptyline and body mass index. CONCLUSION: This analysis demonstrated that compared with traditional antidepressants, CSS combined with antidepressants was more effective and safer for treating depressed patients. MR showed that a causal relationship may exist between amitriptyline and body mass index. Therefore, clinicians should carefully consider the advantages and potential drawbacks of Traditional Chinese Medicine and classic drugs to serve patients better.

The essential oil of Kochia scoparia (L.) Schrad. as a potential repellent against stored-product insects.

Chemical composition of the essential oil from Kochia scoparia (L.) Schrad. (syn. Bassia scoparia (L.) A. J. Scott) was analyzed in quality and quantity by GC-MS and GC-FID. Repellent activities of the essential oil from K. scoparia (KSEO) were evaluated against two common species of stored-product insects Tribolium castaneum Herbst and Liposcelis bostrychophila Badonnel. Results indicated that KSEO mainly consisted of eugenol, ß-caryophyllene, and α-humulene, accounting for 75.6%, 8.2%, and 1.4% of the total oil, respectively. KSEO and the three major components were repellent to T. castaneum and L. bostrychophila adults. Notably, KSEO exerted significant effects, comparable to the positive control DEET at 2 and 4 h post-exposure. Eugenol at 63.17-2.53 nL/cm2 exhibited high percentage repellency ranging from 96 to 70% against L. bostrychophila during 4-h exposure. To gain further insights into the repellent activity, molecular docking simulation was performed with eugenol as the ligand and an odorant binding protein TcOBPC12 (gene: TcOBP10B) from the model insect T. castaneum as the receptor. Docking calculation results revealed that TcOBPC12 had binding affinity to eugenol (△G = - 4.52 kcal/mol) along with a hydrogen bond of 0.18 nm (1.8 Å) long forming between them, which could be an important target protein associated with identifying volatile repellent molecules. This work highlights the promising potential of KSEO as a botanical repellent for controlling stored-product insects.

Molecular identification and genotyping of Blastocystis sp. in sheep and goats from some areas in Inner Mongolia, Northern China.

Blastocystis sp. is a kind of unicellular intestinal commensal which is widely distributed in humans and animals, and frequently found in the people who are in close contact with animals. To investigate the prevalence and evaluate the zoonotic potential of Blastocystis sp. in sheep and goats from Inner Mongolia, China, a total of 1037 samples were collected from them, and subjected to nested PCR amplification based on the small subunit ribosomal RNA (SSU rRNA) gene of Blastocystis sp. The sanger sequencing was used for Blastocystis sp. subtype identification. The results indicated that the average infection rate of Blastocystis sp. was 10.70% [95CI: 8.82%-12.58%] (111/1037), including 11.30% [95CI: 7.96%-14.64%] for sheep (39/345) and 10.40% [95CI: 8.13%-12.67%] for goats (72/692). Five Blastocystis subtypes (ST5, ST10, ST14, ST21 and ST26) were identified in the present study. Among them, ST10 was the most dominant subtype in sheep and goats, accounting for 70.27% (78/111) of the total identified positive samples. This is the first report regarding Blastocystis sp. subtypes ST21 and ST26 in goats in China. This study has provided a detail epidemiological data on the prevalence and subtypes distribution of Blastocystis sp. in sheep and goats in Inner Mongolia, China. Our results indicated that sheep and goats could be reservoir host for multiple Bastocystis subtypes, including the zoonotic subtypes. Further studies among humans, livestock and wild animals are needed to better understand their role in the spread of Blastocystis sp.

Aflatoxin B1 Exposure in Sheep: Insights into Hepatotoxicity Based on Oxidative Stress, Inflammatory Injury, Apoptosis, and Gut Microbiota Analysis.

The widespread fungal toxin Aflatoxin B1 (AFB1) is an inevitable pollutant affecting the health of humans, poultry, and livestock. Although studies indicate that AFB1 is hepatotoxic, there are few studies on AFB1-induced hepatotoxicity in sheep. Thus, this study examined how AFB1 affected sheep liver function 24 h after the animals received 1 mg/kg bw of AFB1 orally (dissolved in 20 mL, 4% v/v ethanol). The acute AFB1 poisoning caused histopathological injuries to the liver and increased total bilirubin (TBIL) and alkaline phosphatase (AKP) levels. AFB1 also markedly elevated the levels of the pro-inflammatory cytokines TNF-α and IL-6 while considerably reducing the expression of antioxidation-related genes (SOD-1 and SOD-2) and the anti-inflammatory gene IL-10 in the liver. Additionally, it caused apoptosis by dramatically altering the expression of genes associated with apoptosis including Bax, Caspase-3, and Bcl-2/Bax. Notably, AFB1 exposure altered the gut microbiota composition, mainly manifested by BF311 spp. and Alistipes spp. abundance, which are associated with liver injury. In conclusion, AFB1 can cause liver injury and liver dysfunction in sheep via oxidative stress, inflammation, apoptosis, and gut-microbiota disturbance.

Quantitative analysis of nutrients for nucleosides, nucleobases, and amino acids hidden behind five distinct regions-derived Poria cocos using ultra-performance liquid chromatography coupled with triple-quadrupole linear ion-trap tandem mass spectrometry.

Poria cocos is an edible fungus used as a health product and traditional Chinese medicinal preparation. Nevertheless, little is known about its nutrients. In this study, ultra-high performance liquid chromatography coupled with triple-quadrupole linear ion-trap tandem mass spectrometry was conducted to quantify nucleosides, nucleobases, and amino acids in 32 batches of Poria cocos samples collected from Anhui, Sichuan, Hubei, Hunan, and Guizhou. Subsequently, the linearity, precision, repeatability, stability, and recovery of our methods were validated. Samples from different regions were clearly separated by partial least squares discriminant analysis and cluster analysis. Our results suggested that Poria cocos samples from different geographical environments differed in nucleosides, nucleobases, and amino acids. The plot of variable importance for projection disclosed differential compositions of L-Leucine, Uridine, L-Asparagine, L-Glutamine, L-phenylalanine, L-Ornithine monohydrochloride, L-Hydroxyproline, Taurine, and Inosine in Poria cocos from five regions. We found the highest content of total analytes, total amino acids, and total non-essential amino acids in Poria cocos from Anhui, total essential amino acids in the Sichuan samples, and total nucleosides in the Hunan samples. Overall, we determined the content of Poria cocos-derived nucleosides, nucleobases, and amino acids, providing the foothold for further chemical mining and use of Poria cocos.

Pharmacokinetics-derived absorbed components responsible for Guizhi-Fuling capsule target PI3K/Akt-Erk to exert an anti-dysmenorrhea effect.

ETHNOPHARMACOLOGICAL RELEVANCE: Guizhi-Fuling capsule (GZFL), a well-known herbal remedy, has been widely used to treat primary dysmenorrhea (PD). Hence, systematic identifying multiple active ingredients and the involved mechanism is essential and urgently needed for GZFL. AIM OF THE STUDY: This study was planned to assess the pharmacokinetics of GZFL in rats, and identify whether these GZFL-derived absorbed components (ACs) contribute to the efficacy of source herbs and relevant mechanism. MATERIALS AND METHODS: The in vivo pharmacokinetic profile of 11 phytochemicals and 13 metabolites in healthy and PD rats were evaluated using liquid chromatography with mass spectrometry (LC-MS/MS). Whereafter, the introduced contribution strategy assessed ACs' effect (doses = their contents in GZFL) in PD rats with the mechanism. RESULT: The pharmacokinetic profiles of prototypes and metabolites differed in healthy and PD rats. As a main proxy of GZFL, 11ACs exerted an anti-PD effect (improvement of indexes for writhing latency, writhing time, PGF2α/PGE2, TXB2/6-keto-PGF1α and ß-EP) by regulating PI3K-Akt/ERK pathway. CONCLUSION: As a paradigmatic example, 11ACs contributed an average of 113.55% to GZFL in terms of anti-PD efficacy, providing an approach to rapidly, accurately and consistently identify the bioactive components and their pathway from herbs.

Molecular characterizations of Giardia duodenalis based on multilocus genotyping in sheep, goats, and beef cattle in Southwest Inner Mongolia, China.

Giardia duodenalis is an important zoonotic parasite that causes economic losses to animal husbandry and threatens public health. In the present study, a total of 1466 fresh fecal samples were collected from sheep (n = 797), goats (n = 561) and beef cattle (n = 108) in Southwest Inner Mongolia, China. Giardia duodenalis was initially screened via nested polymerase chain reaction (PCR) targeting the ß-giardin (bg) gene, and bg-positive samples were subjected to PCR amplification targeting the glutamate dehydrogenase (gdh) and triose phosphate isomerase (tpi) genes. A total of 4.0% of samples (58/1466) were positive for G. duodenalis, with a prevalence of 3.4% in sheep, 3.7% in goats and 5.2% in beef cattle. Three G. duodenalis assemblages (A, B, and E) were identified, with E as the prevalent assemblage. Four and one novel assemblage E sequences were obtained for the gdh and tpi loci, respectively and four assemblage E multilocus genotypes (MLG) were obtained. This study demonstrates high genetic variations in G. duodenalis assemblage E, and provides baseline data for preventing and controlling G. duodenalis infection in livestock in Inner Mongolia.

Title: Caractérisation moléculaire de Giardia duodenalis basée sur le génotypage multilocus chez les ovins, les caprins et les bovins dans le sud-ouest de la Mongolie intérieure, en Chine. Abstract: Giardia duodenalis est un parasite zoonotique important, qui cause des pertes économiques à l'élevage et menace la santé publique. Dans la présente étude, un total de 1466 échantillons fécaux frais ont été prélevés sur des moutons (n = 797), des chèvres (n = 561) et des bovins de boucherie (n = 108) dans le sud-ouest de la Mongolie intérieure, en Chine. Giardia duodenalis a été initialement criblé via une réaction en chaîne par polymérase imbriquée ciblant le gène de la ß-giardine (bg), et les échantillons bg-positifs ont été soumis à une amplification par PCR ciblant les gènes de la glutamate déshydrogénase (gdh) et de la triose phosphate isomérase (tpi). Au total, 4,0 % (58/1466) des échantillons étaient positifs pour G. duodenalis, avec une prévalence de 3,4 % chez les ovins, 3,7 % chez les caprins et 5,2 % chez les bovins. Trois assemblages de G. duodenalis (A, B et E) ont été identifiés, E étant l'assemblage prédominant. Respectivement quatre et une nouvelle séquences de l'assemblage E ont été obtenues dans les loci gdh et tpi, et quatre génotypes multilocus (MLG) de l'assemblage E ont été mis en évidence. Cette étude montre des variations génétiques élevées dans l'assemblage E de G. duodenalis et fournit des données de base pour prévenir et contrôler l'infection à G. duodenalis chez le bétail en Mongolie intérieure.

[Effects and evaluation of different processing and drying methods on components in Paeoniae Radix Alba].

The present study evaluates different processing and drying methods and investigates their effects on the chemical components in Paeoniae Radix Alba via content determination. The fresh medicinal materials of Paeoniae Radix Alba collected from Bozhou of Anhui province were processed(boiled and peeled) and dried(hot air-dried, infrared-dried, and microwave-dried) at different temperatures(40, 50, 60 and 70 ℃), and the 11 components(monoterpene glycosides, polyphenols, tannin, and benzoic acid) in Paeoniae Radix Alba were determined by ultra-performance liquid chromatography coupled to triple quadrupole with electrospray tandem mass spectrometry(UPLC-TQ-MS). Then the compounds in processed and dried samples were analyzed by partial least squares discriminant analysis(PLS-DA) and orthogonal partial least squares discriminant analysis(OPLS-DA), and the contribution rates of differential components were evaluated by variable important in projection(VIP). The results indicated that the samples obtained by different processing and drying methods could be distinguished. Albiflorin, gallic acid, 1,2,3,4,6-pentakis-O-galloyl-ß-D-glucose, and benzoic acid were the common differential components in boiled Paeoniae Radix Alba. Benzoic acid was the common differential component in peeled Paeoniae Radix Alba. Gallic acid was the common differential component in Paeoniae Radix Alba dried by different methods. The samples could not be distinguished after drying at different temperatures due to the lack of common differential components. This study is expected to provide a reference for the selection of processing and drying methods and the optimization of processing parameters.

[Comparative study on differences of Paeonia lactiflora from different habitats based on fingerprint and chemometrics].

This study aims to compare the differences of Paeonia lactiflora from different habitats by establishing fingerprint. The fingerprint of P. lactiflora was established by UPLC. The samples collected from Sichuan,Hebei,Henan,Shanxi and Anhui were analyzed. The common peaks were identified by UPLC-Q-TOF/MS. The relative peak area of the common peaks was analyzed through similarity evaluation system( 2012 edition) for chromatographic fingerprint of traditional Chinese medicine developed by the National Pharmacopoeia Commission. Twelve common peaks were obtained and ten components were identified by reference substance and literature comparison. The similarity of each sample to the reference fingerprint is greater than 0. 900. However,all samples were clearly divided into 5 groups according to habitats after PLS-DA analysis. The peaks 2,6( ethyl gallate),10( galloypaeoniflorin) and 12( benzoyl paeoniflorin) were found to be the main difference components between the samples from five different habitats through the VIP value map. The study found that the variety of ingredients in the different areas are basically similar. But there are some differences in the content of the four components. The results of this study can provide reference at choosing and utilizing P. lactiflora from different places comprehensively.

Down-expression of miR-152 lead to impaired anti-tumor effect of NK via upregulation of HLA-G.

It is known that chronic HBV infection (CHB) is the major risk factor for hepatocellular carcinoma (HCC) because CHB could not only cause liver tumorigenesis but also lead to change of local microenviroment and lower immune response to infected and cancerous cells (immune tolerance). Human leucocyte antigen-G (HLA-G) belongs to a non-classic MHC-I family and was considered to be an immune tolerance molecule, which could bind to immunosuppressive receptors of natural killer cell (NK) and T cells and trigger immunosuppressive signaling. Recently, numerous studies highlighted that microRNAs (miRNAs) were significantly differentially expressed in HCC tumorigenesis, and the expression was tissue-specific, indicating that miRNAs may cause great epigenetic changes in HCC tumorigenesis. In this study, we found that the expression of HLA-G was upregulated by hepatitis B virus (HBV) infection and miR-152; a HLA-G-targeting miRNA was downregulated by HBV infection. And high expression of HLA-G further suppressed NK against cancer cells, providing a new concept that miR-152 was involved in HBV-induced hepatocellular carcinoma.

Expression of immunoglobulin-like transcript (ILT)2 and ILT3 in human gastric cancer and its clinical significance.

Immune inhibitory receptors play an important role in organ transplantation, autoimmune diseases and cancers. Immunoglobulin-like transcript (ILT)2 and ILT3 belong to the inhibitory receptors of the ILT family, which have been reported to regulate a broad range of cellular functions involved in the immune response. They contain immunoreceptor tyrosine-based inhibitory motifs (ITIMs), which are related to immune regulation. Although ILT receptors have been studied in dendritic cells (DCs), T cells, NK cells and other cell types, the expression and clinical significance of ILT2 and ILT3 in gastric cancer have yet to be elucidated. Here, the expression of ILT2 and ILT3 in gastric cancer cell lines and pathologic tissues, as well as their effects on the cytotoxicity of NK92MI against the gastric cancer cell lines MKNI with ILT2lowILT3low and HGC-27 with ILT2highILT3high were detected. The results suggest that ILT2 and ILT3 are expressed with diverse degrees in gastric cancer cells and tissues, and the expression of ILT2 is related with differentiation and size of tumors. Furthermore, the cytotoxic activity of NK92MI against the MKNI cell line was stronger than that against HGC-27. This study indicates that ILT2 and ILT3 play a key role in gastric cancer immune escape, and ILT2 may be a new target in the clinical diagnosis and treatment of gastric cancer.
