Objective: To investigate the clinical efficacy of fecal microbiota transplantation (FMT) for treating steroid-refractory gastrointestinal acute graft-versus-host disease (GI-aGVHD) . Methods: This analysis included 29 patients with hematology who developed steroid-refractory GI-aGVHD after allogeneic hematopoietic stem cell transplantation (allo-HSCT) in Huaian Hospital Affiliated to Xuzhou Medical University from March 2017 to March 2022. Among them, 19 patients underwent FMT treatment (the FMT group) and 10 patients did not (the control group). The efficacy and safety of FMT were assessed, as well as the changes in intestinal microbiota abundance, lymphocyte subpopulation ratio, peripheral blood inflammatory cytokines, and GVHD biomarkers before and after FMT treatment. Results: ① Complete remission of clinical symptoms after FMT was achieved by 13 (68.4%) patients and 2 (20.0%) controls, with a statistically significant difference (P<0.05). Intestinal microbiota diversity increased and gradually recovered to normal levels after FMT and FMT-related infections did not occur. ②The proportion of CD3(+) and CD8(+) cells in the FMT group after treatment decreased compared with the control group, and the ratio of CD4(+), regulatory T cells (Treg), and CD4(+)/CD8(+) cells increased (all P< 0.05). The interleukin (IL) -6 concentration in the FMT group was lower than that in the control group [4.15 (1.91-5.71) ng/L vs 6.82 (2.40-8.91) ng/L, P=0.040], and the IL-10 concentration in the FMT group was higher than that in the control group [12.11 (5.69-20.36) ng/L vs 7.51 (4.10-9.58) ng/L, P=0.024]. Islet-derived protein 3α (REG3α) was significantly increased in patients with GI-aGVHD, and the REG3α level in the FMT group was lower than that in the control group after treatment [30.70 (10.50-105.00) μg/L vs 74.35 (33.50-139.50) μg/L, P=0.021]. Conclusion: FMT is a safe and effective method for the treatment of steroid-refractory GI-aGVHD by restoring intestinal microbiota diversity, regulating inflammatory cytokines, and upregulating Treg cells.

This study aimed to investigate the effective substances and mechanism of Yishen Guluo Mixture in the treatment of chronic glomerulonephritis(CGN) based on metabolomics and serum pharmacochemistry. The rat model of CGN was induced by cationic bovine serum albumin(C-BSA). After intragastric administration of Yishen Guluo Mixture, the biochemical indexes related to renal function(24-hour urinary protein, serum urea nitrogen, and creatinine) were determined, and the efficacy evaluations such as histopathological observation were carried out. The serum biomarkers of Yishen Guluo Mixture in the treatment of CGN were screened out by ultra-performance liquid chromatography-quadrupole time-of-flight/mass spectrometry(UPLC-Q-TOF-MS) combined with multivariate statistical analysis, and the metabolic pathways were analyzed. According to the mass spectrum ion fragment information and metabolic pathway, the components absorbed into the blood(prototypes and metabolites) from Yishen Guluo Mixture were identified and analyzed by using PeakView 1.2 and MetabolitePilot 2.0.4. By integrating metabolomics and serum pharmacochemistry data, a mathematical model of correlation analysis between serum biomarkers and components absorbed into blood was constructed to screen out the potential effective substances of Yishen Guluo Mixture in the treatment of CGN. Yishen Guluo mixture significantly decreased the levels of 24-hour urinary protein, serum urea nitrogen, and creatinine in rats with CGN, and improved the pathological damage of the kidney tissue. Twenty serum biomarkers of Yishen Guluo Mixture in the treatment of CGN, such as arachidonic acid and lysophosphatidylcholine, were screened out, involving arachidonic acid metabolism, glycerol phosphatide metabolism, and other pathways. Based on the serum pharmacochemistry, 8 prototype components and 20 metabolites in the serum-containing Yishen Guluo Mixture were identified. According to the metabolomics and correlation analysis of serum pharmacochemistry, 12 compounds such as genistein absorbed into the blood from Yishen Guluo Mixture were selected as the potential effective substances for the treatment of CGN. Based on metabolomics and serum pharmacochemistry, the effective substances and mechanism of Yishen Guluo Mixture in the treatment of CGN are analyzed and explained in this study, which provides a new idea for the development of innovative traditional Chinese medicine for the treatment of CGN.

Objectives: To investigated the safety and efficacy of treating patients with acute non-ST-segment elevation myocardial infarction (NSTEMI) and elevated levels of N-terminal pro-hormone B-type natriuretic peptide (NT-proBNP) with levosimendan within 24 hours of first medical contact (FMC). Methods: This multicenter, open-label, block-randomized controlled trial (NCT03189901) investigated the safety and efficacy of levosimendan as an early management strategy of acute heart failure (EMS-AHF) for patients with NSTEMI and high NT-proBNP levels. This study included 255 patients with NSTEMI and elevated NT-proBNP levels, including 142 males and 113 females with a median age of 65 (58-70) years, and were admitted in the emergency or outpatient departments at 14 medical centers in China between October 2017 and October 2021. The patients were randomly divided into a levosimendan group (n=129) and a control group (n=126). The primary outcome measure was NT-proBNP levels on day 3 of treatment and changes in the NT-proBNP levels from baseline on day 5 after randomization. The secondary outcome measures included the proportion of patients with more than 30% reduction in NT-proBNP levels from baseline, major adverse cardiovascular events (MACE) during hospitalization and at 6 months after hospitalization, safety during the treatment, and health economics indices. The measurement data parameters between groups were compared using the t-test or the non-parametric test. The count data parameters were compared between groups using the χ² test. Results: On day 3, the NT-proBNP levels in the levosimendan group were lower than the control group but were statistically insignificant [866 (455, 1 960) vs. 1 118 (459, 2 417) ng/L, Z=-1.25,P=0.21]. However, on day 5, changes in the NT-proBNP levels from baseline in the levosimendan group were significantly higher than the control group [67.6% (33.8%,82.5%)vs.54.8% (7.3%,77.9%), Z=-2.14, P=0.03]. There were no significant differences in the proportion of patients with more than 30% reduction in the NT-proBNP levels on day 5 between the levosimendan and the control groups [77.5% (100/129) vs. 69.0% (87/126), χ²=2.34, P=0.13]. Furthermore, incidences of MACE did not show any significant differences between the two groups during hospitalization [4.7% (6/129) vs. 7.1% (9/126), χ²=0.72, P=0.40] and at 6 months [14.7% (19/129) vs. 12.7% (16/126), χ²=0.22, P=0.64]. Four cardiac deaths were reported in the control group during hospitalization [0 (0/129) vs. 3.2% (4/126), P=0.06]. However, 6-month survival rates were comparable between the two groups (log-rank test, P=0.18). Moreover, adverse events or serious adverse events such as shock, ventricular fibrillation, and ventricular tachycardia were not reported in both the groups during levosimendan treatment (days 0-1). The total cost of hospitalization [34 591.00(15 527.46,59 324.80) vs. 37 144.65(16 066.90,63 919.00)yuan, Z=-0.26, P=0.80] and the total length of hospitalization [9 (8, 12) vs. 10 (7, 13) days, Z=0.72, P=0.72] were lower for patients in the levosimendan group compared to those in the control group, but did not show statistically significant differences. Conclusions: Early administration of levosimendan reduced NT-proBNP levels in NSTEMI patients with elevated NT-proBNP and did not increase the total cost and length of hospitalization, but did not significantly improve MACE during hospitalization or at 6 months.

This study aims to study the effective substance and mechanism of Ziziphi Spinosae Semen extract in the treatment of insomnia based on serum metabolomics and network pharmacology. The rat insomnia model induced by p-chlorophenylalanine(PCPA) was established. After oral administration of Ziziphi Spinosae Semen extract, the general morphological observation, pentobarbital sodium-induced sleep test, and histopathological evaluation were carried out. The potential biomarkers of the extract in the treatment of insomnia were screened by ultra-high performance liquid chromatography-mass spectrometry(UHPLC-MS) combined with multivariate analysis, and the related metabolic pathways were further analyzed. The "component-target-pathway" network was constructed by ultra-high performance liquid chromatography coupled with quadrupole-Exactive mass spectrometry(UHPLC-Q-Exactive-MS/MS) combined with network pharmacology to explore the effective substances and mechanism of Ziziphi Spinosae Semen in the treatment of insomnia. The results of pentobarbital sodium-induced sleep test and histopathological evaluation(hematoxylin and eosin staining) showed that Ziziphi Spinosae Semen extract had good theraputic effect on insomnia. A total of 21 endogenous biomarkers of Ziziphi Spinosae Semen extract in the treatment of insomnia were screened out by serum metabolomics, and the metabolic pathways of phenylalanine, tyrosine and tryptophan biosynthesis, phenylalanine metabolism, and nicotinate and nicotinamide metabolism were obtained. A total of 34 chemical constituents were identified by UHPLC-Q-Exactive-MS/MS, including 24 flavonoids, 2 triterpenoid saponins, 4 alkaloids, 2 triterpenoid acids, and 2 fatty acids. The network pharmacological analysis showed that Ziziphi Spinosae Semen mainly acted on target proteins such as dopamine D2 receptor(DRD2), 5-hydroxytryptamine receptor 1 A(HTR1 A), and alpha-2 A adrenergic receptor(ADRA2 A) in the treatment of insomnia. It was closely related to neuroactive ligand-receptor interaction, serotonergic synapse, and calcium signaling pathway. Magnoflorine, N-nornuciferine, caaverine, oleic acid, palmitic acid, coclaurine, betulinic acid, and ceanothic acid in Ziziphi Spinosae Semen may be potential effective compounds in the treatment of insomnia. This study revealed that Ziziphi Spinosae Semen extract treated insomnia through multiple metabolic pathways and the overall correction of metabolic disorder profile in a multi-component, multi-target, and multi-channel manner. Briefly, this study lays a foundation for further research on the mechanism of Ziziphi Spinosae Semen in treating insomnia and provides support for the development of innovative Chinese drugs for the treatment of insomnia.

Quality evaluation of Chinese medicinal decoction pieces is vital for the development of the downstream industries, and is an important channel for implementing the strategy of "higher quality, higher price, and priority for the high quality" for traditional Chinese medicine. At the moment, the quality of Chinese medicinal decoction pieces is mainly evaluated based on chemical component examination. Considering the weak preliminary research foundation and poor research conditions, traditional experience-based evaluation is undervalued in the quality rating of Chinese medicinal decoction pieces. However, traditional experience is a summary of the quality of Chinese medicinal materials based on clinical experience, which thus can be a potential basis for the quality evaluation of the decoction pieces. It is a challenge in the evaluation of Chinese medicinal decoction pieces to objectify the traditional experience-based evaluation from multiple aspects such as chemistry, effect, and characterization via modern techniques. Therefore, this study developed the "experience-ingredients-activity-electronic sensing" evaluation system for Chinese medicinal decoction pieces on the basis of experience-based assessment, chemical ingredients that can truly reflect the traditional experience, biological effect assessment, and electronic sensory evaluation, which is expected to quantify the traditional experience of quality evaluation of Chinese medicinal decoction pieces via chemistry, biology, and sensory simulation. The evaluation system can serve as a reference for clinical experience-based quality evaluation of Chinese medicinal decoction pieces.

Parkinson's disease （PD） is a neurodegenerative disease that seriously endangers the health of the middle-aged and elderly people. The main clinical manifestations include motor symptoms such as bradykinesia， static tremor， and myotonia and non-motor symptoms like constipation， mental disorders， sleep disorders， and autonomic nervous dysfunction. Its etiology and pathogenesis have not been fully understood， and the clinical efficacy is not satisfactory. By searching the relevant literature in China and abroad in recent years， this paper summarized the etiology， pathogenesis， and treatment of PD in both traditional Chinese medicine （TCM） and western medicine as well as the integrated TCM and Western medicine treatment. In general， liver and kidney deficiency is recognized by domestic experts in related fields as the main pathogenesis of PD. The abnormal aggregation of α-synuclein， oxidative stress， mitochondrial dysfunction， ubiquitin-proteasome system dysfunction， neuroinflammation， autophagy， microbiota-gut-brain axis regulation， and excitatory neurotoxicity are closely related to the pathogenesis of this disease. At present， treatment based on syndrome differentiation， empirical formulae from famous doctors， single Chinese herbs， and acupuncture and moxibustion are mainly adopted for the tackling of PD in TCM. Western medicine is still dominated by drug replacement therapy， supplemented by such surgical treatments as traditional immunotherapy， neurotrophic factors， and deep brain stimulation （DBS）， rehabilitation and exercise therapy， and scientific nursing. Gene therapy has become a new technical means for the treatment of this disease in recent years. In addition， the combined therapy of TCM and Western medicine has received increasing importance. This paper reviewed the pathogenesis and treatment of PD in TCM and Western medicine， so as to provide reference for its clinical diagnosis and treatment.

Objective: To explore the association between chronic hepatitis B virus infection and diabetes among adults. Methods: The baseline data of China Kadoorie Biobank ( CKB ) study from Tongxiang of Zhejiang Province was used for analysis. Community residents were investigated in the study from August 2004 to May 2008, including questionnaire survey, physical measurement and biological sample test. Univariate and multivariate logistic regression models were used to estimate the association of chronic hepatitis B virus infection with diabetes. Results: Totally 52 888 participants were included in the final analysis. The overall prevalence of HBsAg-positive was 3.55% ( N=1 877 ). The overall prevalence of diabetes was 5.17% ( N=2 733 ). The prevalence of HBsAg-positive in diabetic patients was 3.51% ( N=96 ). Both univariate and multivariate logistic regression models indicated that there was no association between chronic hepatitis B virus infection and diabetes（ P>0.05 ）. Conclusion No significant association has been found between chronic hepatitis B virus infection and diabetes among adults.

Objective:To explore effects of different extracts and monomers of Lepidium meyenii （Maca） on the proliferation of mouse splenic lymphocytes and induction of interleukin-2 （IL-2） and tumor necrosis factor-α （TNF-α） by observing their immunomodulatory effects. Method:An octadecylsilyl （ODS） column was used to enrich the methanol extract of L. meyenii in stages to obtain six fractions and three monomers. Different groups of extracts and monomers of L. meyenii at different doses were set up. Cell counting Kit-8 （CCK-8） was used to detect the effect on the proliferation of mitogen-free， concanavalin A （Con A）-induced， and lipopolysaccharides （LPS）-induced mouse splenic lymphocytes. Enzyme-linked immunosorbent assay （ELISA） was used to determine the levels of IL-2 and TNF-α. Result:L. meyenii extracts Fr₃ and Fr₆， and monomers N-benzyl hexadecanamide and 1，2-dihydro-4-carboxaldehyde-3-benzyl-N-hydroxypyridine slightly promoted the proliferation of Con A-induced T lymphocytes and LPS-induced B lymphocytes （P<0.01） as compared with the conditions in the model group. L. meyenii extracts and monomers significantly induced the secretion of IL-2 and TNF-α by splenic lymphocytes （P<0.01）. Conclusion:L. meyenii extracts and monomers can achieve immunological enhancement by promoting the secretion of IL-2 and TNF-α， and facilitate the proliferation of splenic lymphocytes. The active components are presumedly macamides and pyridine alkaloids， and the specific mechanism still needs to be further explored.

OBJECTIVETo investigate the effects of ligustrazine (LTZ) on airway inflammation in a mouse model of neutrophilic asthma (NA).

METHODSForty healthy C57BL/6 female mice were randomly divided into 4 groups using a random number table, including the normal control, NA, LTZ and dexamethasone (DXM) groups, with 10 rats in each group. The NA mice model was established by the method of ovalbumin combined with lipopolysaccharide sensitization. At 0.5 h before each challenge, LTZ and DXM groups were intraperitoneally injected with LTZ (80 mg/kg) or DXM (0.5 mg/kg) for 14 d, respectively, while the other two groups were given the equal volume of normal saline. After last challenge for 24 h, the aerosol inhalation of methacholine was performed and the airway reactivity was measured. The bronchoalveolar lavage fluid (BALF) was collected. The Wright-Giemsa staining was used for total white blood cells and differential counts. The levels of cytokines interleukin (IL)-17 and IL-10 were detected by enzyme-linked immunosorbent assay. The pathological change of lung tissue was observed by hematoxylin eosin staining.

RESULTSThe airway responsiveness of the NA group was signifificantly higher than the normal control group (P<0.05), while those in the LTZ and DXM groups were signifificantly lower than the NA group (P<0.05). The neutrophil and eosinophil counts in the LTZ and DXM groups were signifificantly lower than the NA group (P<0.05), and those in the LTZ group were signifificantly lower than the DXM group (P<0.05). There were a large number of peribronchiolar and perivascular inflammatory cells in fifiltration in the NA group. The airway inflflammation in the LTZ and DXM groups were signifificantly alleviated than the NA group. The infifiltration in the LTZ group was signifificantly reduced than the DXM group. Compared with the normal control group, the IL-17 level in BALF was signifificantly increased and the IL-10 level in BALF was signifificantly decreased in the NA group (P<0.05). LTZ and DXM treatment signifificantly decreased IL-17 levels and increased IL-10 levels compared with the NA group (P<0.05), and the changes in the above indices were more signifificant in the LTZ group (P<0.05).

CONCLUSIONLTZ could alleviate the airway inflflammation in the NA mice model through increasing the IL-10 level and decreasing the IL-17 level.
