This study aims to investigate the mechanism of Linderae Radix water extract(LRWE) in the prevention and treatment of diarrhea-predominant irritable bowel syndrome(IBS-D) based on serum metabolomics. Eighteen 2-week-old male SD rats were randomized into control, IBS-D model, and LRWE groups. The rats in other groups except the control group received gavage of senna concentrate combined with restraint stress for the modeling of IBS-D. The rats in the LRWE group were administrated with LRWE(5.4 g·kg~(-1)) by gavage, and those in the control and IBS-D model groups with an equal volume of distilled water for a total of 14 days. The visceral sensitivity was evaluated by the abdominal withdrawal reflex(AWR) score, and the degree of diarrhea was assessed by the fecal water content(FWC). The morphological changes of the colon and the morphology and number of goblet cells were observed by hematoxylin-eosin(HE) and periodic acid-schiff(PAS) staining, respectively. Ultra-high performance liquid chromatography-tandem mass spectrometry(UPLC-MS/MS) was used for the screening of the potential biomarkers in the rat serum and their related metabolic pathways. The results showed that LRWE reduced the AWR score, decreased FWC, and alleviated visceral sensitivity and diarrhea symptoms in IBS-D rats. HE and PAS staining showed that LRWE mitigated low-grade intestinal inflammation and increased the number of mature secretory goblet cells in the colonic epithelium of IBS-D rats. A total of 25 potential biomarkers of LRWE in treating IBS-D were screened out in this study, which were mainly involved in riboflavin, tryptophan, glycine, serine and threonine metabolism, glyoxylate and dicarboxylate metabolism, and cysteine and methionine metabolism. The regulatory effects were the most significant on the riboflavin and tryptophan metabolism pathways. LRWE may alleviate the visceral hypersensitivity by promoting energy metabolism and amino acid metabolism, enhancing intestinal barrier function, and improving intestinal immune function in IBS-D rats.

OBJECTIVE:
To re-evaluate the systematic review/Meta-analysis of acupuncture and moxibustion for childhood autism (CA), aiming to provide decision-making basis for clinical diagnosis and treatment.
METHODS:
The systematic review and/or Meta-analysis of acupuncture and moxibustion for CA were searched in PubMed, EMbase, Cochrane Library, SinoMed, CNKI and Wanfang databases. The retrieval time was from the database establishment to May 5th, 2022. PRISMA (preferred reporting items for systematic reviews and Meta-analyses) was used to evaluate the report quality, and AMSTAR 2 (a measurement tool to assess systematic reviews 2) was used to evaluate the methodological quality, bubble map was used to construct the evidence map and GRADE was used to evaluate the quality of evidence.
RESULTS:
A total of 9 systematic reviews were included. The PRISMA scores ranged from 13 to 26. The report quality was low, and there was a serious lack in the aspects of program and registration, search, other analysis and funding. The main problems in methodology included not making prespecified protocol, incomplete retrieval strategy, not providing a list of excluded literatures, and incomplete explanation on heterogeneity analysis and bias risk. The evidence map showed that 6 conclusions were valid, 2 conclusions were possible valid and 1 conclusion was uncertain valid. The overall quality of evidence was low, and the main factors leading to the downgrade were limitations, followed by inconsistency, imprecision and publication bias.
CONCLUSION
Acupuncture and moxibustion has a certain effect for CA, but the quality of reporting, methodology and evidence in included literature need to be improved. It is suggested to perform high-quality and standardized research in the future to provide evidence-based basis.

Objective:To evaluate the diagnostic value of 1, 3-β-D glucan (BDG), mannan IgM antibody (Mn-IgM) and mannan IgG antibody (Mn-IgG) in invasive candidiasis and to compare the differences in the diagnostic capability of serological markers used alone or in combination.Methods:Serum samples of 126 patients with invasive candidiasis and 104 healthy people who took physical examination during the same period were collected. BDG was detected by dynamic chromogenic method, and Mn-IgM and Mn-IgG were detected by ELISA. The sensitivity, specificity, positive predictive value, negative predictive value, Youden index, coincidence rate and Kappa value of the three serological markers used alone or in combination in the diagnosis of invasive candidiasis were analyzed and compared. The receiver operating characteristic (ROC) curves were drawn and the areas under the curves (AUCs) were calculated.Results:The levels of BDG, Mn-IgM and Mn-IgG in patients with invasive candidiasis were significantly higher than those in healthy people ( P<0.01). The sensitivity, specificity, Kappa value and AUC of BDG were 48.41%, 92.31%, 0.389 and 0.842. The sensitivity, specificity, Kappa value and AUC of Mn-IgM were 64.29%, 91.35%, 0.540 and 0.829. The sensitivity, specificity, Kappa value and AUC of Mn-IgG were 27.78%, 95.19%, 0.214 and 0.737. The sensitivity, specificity, Kappa value and AUC of BDG+ Mn-IgM were 76.19%, 88.46%, 0.637 and 0.921. The sensitivity, specificity, Kappa value and AUC of BDG+ Mn-IgG were 59.52%, 91.35%, 0.491 and 0.856. The sensitivity, specificity, Kappa value and AUC of Mn-IgM+ Mn-IgG were 69.84%, 90.38%, 0.588 and 0.891. The sensitivity, specificity, Kappa value and AUC of BDG+ Mn-IgM+ Mn-IgG were 80.16%, 88.46%, 0.679 and 0.922. Conclusions:The sensitivity of Mn-IgM was higher than that of BDG and Mn-IgG in the diagnosis of invasive candidiasis. When the serological biomarkers were used in combination, BDG+ Mn-IgM and BDG+ Mn-IgM+ Mn-IgG had relatively high Kappa value and AUC, showing high accuracy. The clinical diagnostic value of multiple serological biomarkers used in combination was significantly higher than that of any serological biomarkers used alone. Early combined detection and continuous monitoring of multiple serological biomarkers in patients with high risk of invasive candidiasis could be used clinically to adjust antifungal treatment strategies timely.

ObjectiveTo investigate the intervention effect of Danggui Buxuetang on oxidative stress and inflammatory response in diabetic kidney disease (DKD) rats from its improvement of podocyte mitochondrial dysfunction. MethodSD rats were randomly divided into the control group and modeling group, and the ones in the latter group rats were fed a high-glucose and high-fat diet and then intraperitoneally injected with a small dose of streptozotocin (STZ) for inducing type 2 diabetes. The successfully modeled rats were randomized into the model group, high- and low-dose (1.44 and 0.72 g·kg-1) Danggui Buxuetang groups, and irbesartan (0.017 g·kg-1)group and gavaged with the corresponding drugs, while those in the normal and model groups with an equal volume of normal saline. After 20 weeks of drug intervention, the urinary microalbumin-to-urine creatinine ratio (UACR) and serum malondialdehyde (MDA) content and manganese superoxide dismutase (MnSOD) activity in each group were measured. The pathological changes in renal tissue were observed by Masson trichrome staining, and periodic acid-silver metheramine (PASM) staining, followed by the observation of ultrastructural changes in podocytes under the transmission electron microscope (TEM). The expression level of reactive oxygen species (ROS) in rat kidney tissue was detected using a fluorescent probe dihydroethidium (DHE). The protein expression levels of peroxisome proliferator-activated receptor γ -coactivator -1α (PGC-1α), nucleotide-binding domain like receptor protein 3 (NLRP3), and Wilms tumor protein-1 (WT-1) were measured by immunohistochemistry (IHC), and the expression levels of NLRP3, interleukin-1β (IL-1β),and WT-1 in podocytes by immunofluorescence (IF) assay. The mRNA expression levels of PGC-1α and NLRP3 in the renal tissues were determined by real-time fluorescence quantitative polymerase chain reaction (Real-time PCR), and the protein expression levels of PGC-1α, MnSOD, NLRP3, and IL-1β were assayed by Western blot. ResultCompared with the normal group, the model group exhibited elevated UACR and MDA content, weakened MnSOD activity (P<0.01), glomerular hypertrophy, thickened basement membrane, mesangial hyperplasia, increased extracellular matrix, K-W nodules, podocyte mitochondrial swelling, disordered mitochondrial cristae, foot process fusion or loss, vacuolization, increased ROS (P<0.01), enhanced NLRP3 and IL-1β but diminished WT-1 expression in podocytes, down-regulated PGC-1α mRNA expression (P<0.01) and PGC-1α and MnSOD protein expression (P<0.01), and up-regulated NLRP3 mRNA expression and NLRP3 and IL-1β protein expression (P<0.01). Compared with the model group, Danggui Buxuetang high-dose group significantly decreased UACR and MDA, enhanced MnSOD activity (P<0.05, P<0.01), improved renal histopathology and podocyte mitochondrial ultrastructure, decreased ROS (P<0.05, P<0.01) and NLRP3 and IL-1β expression in podocytes, enhanced WT-1 expression in podocytes, up-regulated the mRNA and protein levels of PGC-1α and MnSOD, and down-regulated the mRNA and protein levels of NLRP3 and IL-1β (P<0.05, P<0.01). ConclusionDanggui Buxuetang alleviates oxidative stress, reduces inflammatory response, protects kidney, and delays the progression of DKD possibly by improving the mitochondrial dysfunction in podocytes of DKD rats.

ObjectiveTo observe the effect of Danggui Buxuetang on podocyte pyroptosis in diabetic kidney disease (DKD) rats and to explore the possible mechanism of its prevention and treatment of DKD and podocyte pyroptosis. MethodEight of the 50 male SD rats were randomly classified into a normal group, and the remaining 42 were fed a high-glucose and high-fat diet for six weeks and then intraperitoneally injected with 35 mg·kg-1 streptozotocin (STZ) for inducing type 2 diabetes. After successful modeling, they were randomized into the model group, low- (0.72 g·kg-1) and high-dose (1.44 g·kg-1) Danggui Buxuetang group, and irbesartan (0.017 g·kg-1) group and gavaged with the corresponding drugs, while those in the normal group and model group with an equal volume of normal saline, once per day, for 20 weeks. During the medication, the fasting blood glucose (FBG) and 24 h urine protein (24 h-UTP) were measured regularly. After administration, the pathological changes in renal tissues were observed by periodic acid-silver metheramine (PASM) staining, followed by the observation of ultrastructural changes in podocytes under the transmission electron microscope (TEM). Serum levels of interleukin-1β (IL-1β) and interleukin-18 (IL-18) were determined by enzyme-linked immunosorbent assay (ELISA).

Idiopathic asthenozoospermia, a common factor in male infertility, is characterized by altered sperm motility function in fresh ejaculate. Although the β-defensin 126 (DEFB126) protein is associated with asthenozoospermia, DEFB126 gene polymorphisms have not been extensively studied. Therefore, the association between DEFB126 gene polymorphisms and asthenozoospermia requires further investigation. Screening was performed by semen analysis, karyotype analysis, and Y microdeletion detection, and 102 fertile men and 106 men with asthenozoospermia in Chengdu, China, were selected for DEFB126 gene sequence analyses. Seven nucleotide mutations and two nucleotide deletions in the DEFB126 gene were detected. rs11467417 (317-318 del/del), rs11467497 (163-166 wt/del), c.152T>C, and c.227A>G were significantly different between the control and asthenozoospermia groups, likely representing high-risk genetic factors for asthenozoospermia among males. DEFB126 expression was not observed in sperm with rs11467497 homozygous deletion and was unstable in sperm with rs11467417 homozygous deletion. The rs11467497 four-nucleotide deletion leads to truncation of DEFB126 at the carboxy-terminus, and the rs11467417 binucleotide deletion produces a non-stop messenger RNA (mRNA). The above deletions may be responsible for male hypofertility and infertility by reducing DEFB126 affinity to sperm surfaces. Based on in silico analysis, the amino acids 51M and 76K are located in the highly conserved domain; c.152T>C (M51T) and c.227A>G (K76R) are predicted to be damaging and capable of changing alternative splice, structural and posttranslational modification sites of the RNA, as well as the secondary structure, structural stability, and hydrophobicity of the protein, suggesting that these mutations are associated with asthenozoospermia.

Polyethylene glycol (PEG) surface film-forming method was used to prepare hydrophilic Indigo Naturalis decoction pieces with stable effect.The preparation process of modified Indigo Naturalis was optimized and its microscopic properties,hydrophilicity,antipyretic efficacy,and safety were systematically evaluated.With equilibrium contact angle as assessment index,the influence of modifier type,modifier dosage,dispersant dosage,and co-grinding time on water solubility of Indigo Naturalis was investigated by single factor test.The results showed that the optimal preparation process was as follows.The 6%PEG6000 is dissolved in 10%anhydrous ethanol solution by sonification and then the mixture is ground with Indigo Naturalis for 2 min.The resultant product is dried on a square tray in an oven at 60℃to remove ethanol and thereby the PEG-modified hydrophilic Indigo Naturalis decoction pieces are yielded.The morphological observation under scanning electron microscope (SEM) indicated that the modified Indigo Naturalis had smoother surface than Indigo Naturalis,and energy spectrometer measurement showed that the nitrogen (N),calcium(Ca),oxygen (O),and silicon (Si) on the surface of modified Indigo Naturalis powder were less than those of Indigo Naturalis powder.Modified Indigo Naturalis had the equilibrium contact angle 18.96°smaller,polar component 22.222 m J·m~(-2)more,and nonpolar component 7.277 m J·m~(-2)smaller than the Indigo Naturalis powder.Multiple light scattering technique was employed to evaluate the dispersion in water and the result demonstrated that the transmittance of Indigo Naturalis and modified Indigo Naturalis was about85%and 75%,respectively,suggesting the higher dispersity of modified Indigo Naturalis.The suspension rate of modified Indigo Naturalis in water was determined by reflux treatment.The result showed that 57%of Indigo Naturalis was not wetted after refluxing for1 h,while the modified Indigo Naturalis was all wetted and dispersed into water.The dissolution of indigo and indirubin of modified Indigo Naturalis increased and the process was more stable.Then,rats were randomized into the blank group,model group,acetaminophen group,Indigo Naturalis group,and hydrophilic Indigo Naturalis group.The temperature changes of rats were observed after administration and the concentration of IL-1βand TNF-αin serum and IL-1βand PGE_2in hypothalamus was measured.The results indicated that the temperature of Indigo Naturalis group and hydrophilic Indigo Naturalis group dropped and the IL-1βlevel of the hydrophilic Indigo Naturalis group decreased (P<0.05) as compared with those in the model group.Thus,both Indigo Naturalis and hydrophilic Indigo Naturalis had antipyretic effect,particularly the hydrophilic Indigo Naturalis.The acute toxicity test of hydrophilic Indigo Naturalis verified that it had no toxicity to rats.In this study,the hydrophilic Indigo Naturalis decoction pieces were prepared with the PEG surface film-forming method,and the antipyretic efficacy and safety were evaluated,which expanded the technological means of powder modification for Chinese medicine and provided a method for clinical use of Chinese medicine.
