RESUMEN
BACKGROUND: Sacral nerve neuromodulation (SNM) has been considered the optimal second-line treatment for fecal incontinence (FI). However, SNM involves high cost and requires highly skilled operators. Percutaneous tibial nerve stimulation (PTNS) has emerged as an alternative treatment modality for FI, yielding varying clinical outcomes. We conducted this meta-analysis to evaluate the effectiveness and safety of PTNS compared to sham electrical stimulation for FI. METHODS: PubMed, Embase, Web of Science, and the Cochrane Library were searched for studies from May 12, 2012 to May 12, 2022. RESULTS: Four randomized controlled studies were included in this review, involving a total of 439 adult patients with FI (300 in the PTNS group and 194 in the sham electrical stimulation group). Our meta-analysis revealed that PTNS demonstrated superior efficacy in reducing weekly episodes of FI compared to the control groups (MD - 1.6, 95% CI - 2.94 to - 0.26, p = 0.02, I2 = 30%). Furthermore, a greater proportion of patients in the PTNS group reported more than a 50% reduction in FI episodes per week (RR 0.73, 95% CI 0.57-0.94, p = 0.02, I2 = 6%). However, no significant differences were observed in any domains of the FI Quality of Life (QoL) and St Mark's incontinence scores (MD - 2.41, 95% CI - 5.1 to 0.27, p = 0.08, I2 = 67%). Importantly, no severe adverse events related to PTNS were reported in any of the participants. CONCLUSIONS: Our meta-analysis revealed that PTNS was more effective than sham stimulation in reducing FI episodes and led to a higher proportion of patients reporting more than a 50% reduction in weekly FI episodes.

OBJECTIVE: The aim of this study was to investigate the expression levels of the serum transforming growth factor-ß1 (TGF-ß1) CXC type chemokine ligand 13 (CXCL13) in primary Sjogren's syndrome (pSS) patients and its correlation with disease severity. METHOD: Thirty patients with pSS admitted to Nanjing Traditional Chinese Medicine Affiliated Hospital of Nanjing University of Traditional Chinese Medicine from January 2021 to December 2022 were included as the pSS group, while 30 patients who underwent physical examination during the same period were included as the control group. The levels of TGF-ß1 and CXCL13 were detected. The diagnostic value of TGF-ß1 and CXCL13 for pSS was analyzed. Detection of serum TGF-ß1 and CXCL13 levels in pSS patients with different disease activities and lip gland pathological grading of pSS was done. We compared the correlation between TGF-ß1 and CXCL13 levels and disease activity and labial gland pathological grading in pSS patients. RESULT: The TGF-ß1 and CXCL13 levels in the pSS group were higher than those in the control group. The area under the receiver operating characteristic (ROC) curve (AUC) for TGF-ß1 and CXCL13 diagnosis of pSS was 0.790 (95% confidence interval (CI): 0.720~0.861) and 0.838 (95% CI: 0.778~0.898), respectively. The serum TGF-ß1 and CXCL13 levels of pSS patients significantly increase with the increase of disease activity and lip gland pathological grading. The TGF-ß1 and CXCL13 levels in pSS patients were positively correlated with disease activity and lip gland pathological grading. CONCLUSION: The levels of TGF-ß1 and CXCL13 in pSS patients were increased, and it was closely related to disease activity and lip gland pathological grading, which can be used as an effective indicator for the diagnosis of pSS. Key Points ⢠The TGF-ß1 and CXCL13 levels in the pSS group were higher than those in the control group. ⢠The TGF-ß1 and CXCL13 levels in pSS patients were positively correlated with disease activity and lip gland pathological grading. ⢠TGF-ß1 and CXCL13 can be used as an effective indicator for the diagnosis of pSS.

UGT1A1 is the main enzyme that catalyzes the metabolic elimination and detoxification of SN-38, the active form of the drug irinotecan. Milk thistle products have been used widely to protect the liver from injury associated with the use of chemotherapeutic agents. To evaluate whether SN-38 metabolism can be affected by milk thistle products, the inhibitory effects of silybins on UGT1A1*1 and UGT1A1*6 were evaluated in the present investigation. Both silybin A and silybin B potently inhibited SN-38 glucuronidation catalyzed by UGT1A1*1 or UGT1A1*6. It was noteworthy that silybin A and silybin B showed synergistic effect in UGT1A1*1 microsomes at concentration around IC50, while additive effect in UGT1A1*6. According to the predicted AUCi/AUC ratios (the ratio of the area under the plasma concentration-time curve of SN-38 in the presence and absence of silybins), the coadministration of irinotecan and several milk thistle products, including silybin-phosphatidylcholine complex, two Legalon capsules, four Silymarin tablets or four Liverman capsules, may lead to clinically significant herb-drug interactions (HDI) via UGT1A1 inhibition. Meanwhile, Rgut values were much higher than 11 in all the groups, indicating potential HDI due to intestinal UGT1A1 inhibition.

OBJECTIVE: Depression and metabolic disorders have overlapping psychosocial and pathophysiological causes. Current research is focused on the possible role of adiponectin in regulating common biological mechanisms. Xiaoyao San (XYS), a classic Chinese medicine compound, has been widely used in the treatment of depression and can alleviate metabolic disorders such as lipid or glucose metabolism disorders. However, the ability of XYS to ameliorate depression-like behavior as well as metabolic dysfunction in mice and the underlying mechanisms are unclear. METHODS: An in vivo animal model of depression was established by chronic social defeat stress (CSDS). XYS and fluoxetine were administered by gavage to the drug intervention group. Depression-like behaviors were analyzed by the social interaction test, open field test, forced swim test, and elevated plus maze test. Glucose levels were measured using the oral glucose tolerance test. The involvement of certain molecules was validated by immunofluorescence, histopathology, and Western blotting. In vitro, hypothalamic primary neurons were exposed to high glucose to induce neuronal damage, and the neuroprotective effect of XYS was evaluated by cell counting kit-8 assay. Immunofluorescence and Western blotting were used to evaluate the influences of XYS on adiponectin receptor 1 (AdipoR1), adenosine 5'-monophosphate-activated protein kinase (AMPK), acetyl-coenzyme A carboxylase (ACC) and other related proteins. RESULTS: XYS ameliorated CSDS-induced depression-like behaviors and glucose tolerance impairment in mice and increased the level of serum adiponectin. XYS also restored Nissl bodies in hypothalamic neurons in mice that exhibited depression-like behaviors and decreased the degree of neuronal morphological damage. In vivo and in vitro studies indicated that XYS increased the expression of AdipoR1 in hypothalamic neurons. CONCLUSION: Adiponectin may be a key regulator linking depression and metabolic disorders; regulation of the hypothalamic AdipoR1/AMPK/ACC pathway plays an important role in treatment of depression by XYS.

This article investigated the role and the specific mechanism of Ruscogenin in Sjögren's syndrome (SS). NOD/ShiLtJ mice were treated with Ruscogenin, and acinar cells isolated from submandibular glands were treated with TNF-α, Ruscogenin and transfected with NLRP3 overexpression plasmid. Salivary flow rate (SFR) was measured at weeks 11, 13, 15, 17, and 20. Histological analysis of the submandibular glands was conducted by hematoxylin-eosin staining assay. IL-6, IL-17, TNF-α, and IL-1ß mRNA expression was detected through qRT-PCR. AQP 5, AQP 4, P2X7R, NLRP3, caspase 1, IL-1ß, Bax, and Bcl-2 protein levels were tested by western blot. Cell apoptosis was assessed through acridine orange and propidium iodide (AO/PI) staining assay and flow cytometry assay. Ruscogenin ameliorated the SFR and submandibular gland inflammation of NOD/ShiLtJ mice. Ruscogenin promoted the preservation of acinar cells and suppressed inflammation-related factors (P2X7R, NLRP3, caspase 1, and IL-1ß) in submandibular gland tissues of NOD/ShiLtJ mice. Ruscogenin inhibited acinar cell apoptosis in NOD/ShiLtJ mice and reversed TNF-α-induced apoptosis and inflammation of acinar cells. NLRP3 overexpression reversed the repressive effect of Ruscogenin on TNF-α-induced inflammation and apoptosis of acinar cells. Ruscogenin ameliorated SS by inhibiting NLRP3 inflammasome activation.
RESUMEN
BACKGROUND: Attention deficit hyperactivity disorder (ADHD) is a neurodevelopmental disorder diagnosed during adolescence and adulthood. Assessment of the long-term risks of the current drugs for ADHD treatment has been insufficient, and little is known concerning the long-term therapeutic effects of psychostimulants. Commercially available traditional Chinese medicine compound oral preparations [e.g., Dimu Ningshen (DMNS)] have been widely used in the clinical treatment of ADHD, but their influence on the interaction between gut microbes and potential metabolomes remains inconclusive. METHODS: We used a series of behavioral experiments to evaluate the behavioral effects of DMNS on adolescent and adult ADHD rats and used 16S rDNA sequencing of gut microbes and nontarget metabolomics to evaluate the potential pathogenesis of ADHD and explore the biological mechanism of DMNS in ADHD treatment. RESULTS: For the first time, DMNS was shown to reduce the excessive activity of adult and adolescent ADHD rats and improve the attention deficit of adult ADHD rats. DMNS improved the structural composition of the ADHD gut microbiota and reduced the abundance of Ruminococcaceae_NK4A214_group, Ruminococcus_2, and Eubacterium_nodatum_group. Simultaneously, DMNS increased the circulating levels of peripheral monoamine neurotransmitter precursors (e.g., phenylalanine) and reduced the circulating levels of peripheral fatty acid amides (e.g., oleamide). Finally, the changes in the ADHD serum metabolites were strongly correlated with the gut microbiota. CONCLUSION: DMNS has a good effect in treating ADHD, and it may exert this effect by regulating the gut microbiota and affecting metabolites in the peripheral circulation.

BACKGROUND: Taxol is an efficient anticancer drug accumulated in Taxus species. Pseudotaxus chienii is an important member of Taxaceae, however, the level of six taxoids in P. chienii is largely unknown. RESULTS: High accumulation of 10-DAB, taxol, and 7-E-PTX suggested that P. chienii is a good taxol-yielding species for large-scale cultivation. By the omics approaches, a total of 3,387 metabolites and 61,146 unigenes were detected and annotated. Compared with a representative Taxus tree (Taxus yunnanensis), most of the differentially accumulated metabolites and differential expressed genes were assigned into 10 primary and secondary metabolism pathways. Comparative analyses revealed the variations in the precursors and intermediate products of taxol biosynthesis between P. chienii and T. yunnanensis. Taxusin-like metabolites highly accumulated in P. chienii, suggesting a wider value of P. chienii in pharmaceutical industry. CONCLUSIONS: In our study, the occurrence of taxoids in P. chienii was determined. The differential expression of key genes involved in the taxol biosynthesis pathway is the major cause of the differential accumulation of taxoids. Moreover, identification of a number of differentially expressed transcription factors provided more candidate regulators of taxol biosynthesis. Our study may help to reveal the differences between Pseudotaxus and Taxus trees, and promote resource utilization of the endangered and rarely studied P. chienii.

AIM: To study the influence of total glucosides of paeony (TGP) on the expression of peripheral blood programmed cell death protein 1 (PD-1) and its ligand (PD-L1) in patients with primary Sjögren's syndrome (pSS). METHOD: Ten patients with new-onset pSS were selected as the experimental group and were treated with 1.8 g of TGP (the main ingredient is Radix Paeoniae Alba) daily for 3 months; furthermore, 10 physically healthy individuals were selected as the control group. Peripheral blood mononuclear cells were isolated, and flow cytometry was used to detect PD-1 expression on the surface of CD4+ T and CD8+ T lymphocytes and PD-L1 expression on the surface of CD14+ monocytes and CD19+ B cells before and after treatment in the experimental and control groups. Furthermore, plasma levels of soluble PD-1 (sPD-1), interleukin (IL)-10, and IL-17A were also determined using enzyme-linked immunosorbent assay. RESULTS: The PD-1 expression on the surface of CD4+ T and CD8+ T lymphocytes in the peripheral blood of patients with pSS were significantly higher than in the control group (P < 0.001). However, PD-L1 expression on the surface of CD14+ monocytes declined but not significantly (P > 0.05), and PD-L1 expression on the surface of CD19+ B cells increased significantly (P < 0.001). Moreover, sPD-1 and IL-17A levels in the plasma of the experimental group were significantly higher than in the control group (P < 0.001), but the IL-10 level was significantly lower than in the control group (P < 0.001). After TGP treatment, PD-1 expression on the surface of CD4+ T and CD8+ lymphocytes in the peripheral blood of patients with pSS had decreased significantly (P < 0.001); the PD-L1 expression on the surface of CD19+ cells had decreased significantly (P < 0.001); and the PD-L1 expression on the surface of CD14+ monocytes did not differ significantly (P > 0.05). Furthermore, the levels of sPD-1 and IL-17A in plasma had decreased (P < 0.01) and IL-10 levels had increased after TGP treatment (P < 0.01). CONCLUSION: PD-1/PD-L1 molecules expressed on the surface of T cells, B cells, and monokaryon participated in the pathogenesis and development of SS through interactions. Therefore, TGP, which may increase the expression of PD-1 and its relevant ligand PD-L1 in the peripheral blood mononuclear cells, may play a role in the pathogenesis and development of SS through the PD-1/PD-L1 pathway by regulating regulatory T cells/T helper cell 17.

BACKGROUND: In rice, the pistil is the female reproductive organ, and it consists of two stigmas and an ovary. The stigma is capable of receiving pollen grains and guiding pollen tube growth. The ovary holds the embryo sac, which is fertilized with male gametes to produce seed. However, little is known about the gene function and regulatory networks during these processes in rice. RESULTS: Here, using the RNA-Seq technique, we identified 3531 stigma-preferential genes and 703 stigma-specific genes within the rice pistils, and we verified 13 stigma-specific genes via qRT-PCR and in situ hybridization. The GO analysis showed that the transport-, localization-, membrane-, communication-, and pollination-related genes were significantly enriched in the stigma. Additionally, to identify the embryo sac-preferential/specific genes within the pistils, we compared a wild-type ovary with a mutant dst (defective stigma) ovary and found that 385 genes were down-regulated in dst. Among these genes, 122 exhibited an ovary-specific expression pattern and are thought to be embryo sac-preferential/specific genes within the pistils. Most of them were preferentially expressed, while 14 of them were specifically expressed in the pistil. Moreover, the rice homologs of some Arabidopsis embryo sac-specific genes, which played essential roles during sexual reproduction, were down-regulated in dst. Additionally, we identified 102 novel protein-coding genes, and 6 of them exhibited differences between the stigma and ovary in rice as determined using RT-PCR. CONCLUSIONS: According to these rice ovary comparisons, numerous genes were preferentially or specifically expressed in the stigma, suggesting that they were involved in stigma development or pollination. The GO analysis indicated that a dry rice stigma might primarily perform its function through the cell membrane, which was different from the wet stigma of other species. Moreover, many embryo sac-preferential/specific genes within the pistils were identified and may be expressed in female rice gametophytes, implying that these genes might participate in the process of female gametophyte specialization and fertilization. Therefore, we provide the gene information for investigating the gene function and regulatory networks during female gametophyte development and fertilization. In addition, these novel genes are valuable for the supplementation and perfection of the existing transcriptome in rice, which provides an effective method of detecting novel rice genes.

Objective To evaluate the efficacy and safety of Liujin Runzao Concentrated Decoction (LRCD) for the treatment of primary Sjögren's syndrome (pSS). Methods Forty pSS patients with fluid depletion and distribution obstacles syndrome (FDDOS) were randomly assigned to the experimen- tal group and the control group according to 1:1 proportion. All patients received standard therapy: Radix Paeoniae alba total glycosides 600 mg, twice per day. Patients in the experimental group additionally took LRCD, 30 mL each time, twice per day. The therapeutic course for all was 4 weeks, and two courses for all. The improvement of dry mouth and dry eyes were comprehensively evaluated. Each outcome of composite index constitutions (integrals of dry eyes and dry mouth, salivary flow rate, Schirmer test) was respectively reported. Schirmer test and salivary flow rate were determined as well. Score of TCM syndrome, blood sedimentation,'immunoglobulin, and adverse drug reactions were observed. Results The effective rate of comprehensive effect for dry eyes and dry mouth improvement at the end of 8 weeks was 80% in the experimental group and 35% in the control group, with statistical difference (X² =8. 286, P <0. 05). As for the composition of comprehensive effect for dry eyes and dry mouth improvement: The score for dry eyes and dry mouth decreased in the two groups more after treatment than before treatment. The difference in pre-post treatment score for dry eyes and dry mouth at week 8 was higher in the experimental group than in the control group. The difference in pre-post treatment score at week 8 was 1. 71 (95% Cl: -0. 37 -3. 78) between the two groups (P <0. 05). The difference in pre-post treatment Schirmer test and salivary flow rate at week 8 was higher in the experimental group than in the control group, but with on statistical difference (P >0. 05). The difference in pre-post treatment Schirmer test and salivary flow rate at week 8 was 2. 74 mL/15 min (95% Cl: 0. 49 -4.98) and 0. 13 mm/5 min (95% Cl: 0. 92 -1. 23) between the two groups (P <0. 05). The score of TCM syndrome decreased more in the two groups, as compared with before treatment. The difference in pre-post treatment score of TCM syn- drome at week 8 was 1. 71 (95% CI: -1. 40 -4. 81) between the two groups (P >0. 05). One case of uri- nary tract infections occurred in the control group, while no obvious adverse event occurred in the exper- imental group. Conclusion Standard treatment combined LRCD showed better comprehensive effect for dry eyes and dry mouth in pSS patients with FDDOS, and was more safe.
