ObjectiveTo establish the specific chromatogram and quantitative analysis of multi-components by single-marker(QAMS) based on linear calibration using two reference substances(LCTRS), explore the consistency between Hedyotis Herba dispensing granules and standard decoction, and evaluate the quality of the dispensing granules. MethodsHigh performance liquid chromatography(HPLC) specific chromatogram was established based on 15 batches of Hedyotis Herba standard decoction and 10 batches of the dispensing granules, and LCTRS was used to locate chromatographic peaks. The actual retention times of 7 characteristic peaks in the specific chromatogram was measured on 24 different types of C18 columns, taking deacetyl asperulosidic acid and asperulosidic acid as the dual standard compounds, the retention times of the other 5 characteristic peaks were predicted and validated. Based on this, QAMS was developed to determine the contents of four components(deacetyl asperulosidic acid, deacetyl asperulosidic acid methyl ester, asperulosidic acid, and p-coumaric acid). Then, the relative correction factors of deacetyl asperulosidic acid, deacetyl asperulosidic acid methyl ester and p-coumaric acid were calculated using the reference peak of asperulosidic acid in the dual standard compounds, and each component was quantified accordingly. Finally, the consistency between the dispensing granules and standard decoction was assessed by taking extract rate of the standard decoction, consistency of the specific chromatograms, contents and transfer rates of the indicator components as indexes, and the quality of the dispensing granules was evaluated. ResultsThere were 7 common peaks in the characteristic chromatogram of samples of Hedyotis Herba standard decoction and the dispensing granules, and four of them were identified by reference standards, namely deacetyl asperulosidic acid(peak 1), deacetyl asperulosidic acid methyl ester(peak 3), asperulosidic acid(peak 6) and p-coumaric acid(peak 7). The similarity between the dispensing granules and the standard decoction was >0.9. The absolute deviation in the predicted retention time for each component by LCTRS was lower than that of the relative retention time method. The extract rate of the 15 batches of Hedyotis Herba standard decoction ranged from 7.89% to 14.60%, the contents of deacetyl asperulosidic acid, deacetyl asperulosidic acid methyl ester, asperulosidic acid and p-coumaric acid were 6.62-19.70, 3.83-17.99, 1.57-6.69, 1.62-4.52 mg·g-1, and the transfer rates of these components from decoction pieces to the standard decoction were 22.89%-39.60%, 34.03%-62.24%, 24.25%-43.70%, and 40.58%-73.71%, respectively. The extract rate, index component contents and transfer rates from decoction pieces to the three batches of Hedyotis Herba dispensing granules(P1-P3), produced by manufacturer A, were similar to those of the standard decoction prepared from the same batch of decoction pieces, and all fell within the specified range. The contents of the 4 indicator components in 7 batches of the dispensing granules(P4-P10) from manufacturers B-E were all within the range of the content converted from the standard decoction based on the quantity of the dispensing granules. ConclusionThe established specific chromatogram and QAMS based on LCTRS are reasonable and reliable. Based on the evaluation indicators of standard decoction yield, consistency of specific chromatograms, contents and transfer rates of the four index components, the 10 batches of Hedyotis Herba dispensing granules from various manufacturers have exhibited good consistency with the standard decoction, indicating that the current production process is relatively reasonable.

Traditional medications used for treating autoimmune diseases often come with a wide range of adverse effects. Current treatments focus mainly on symptom management, resulting in significant health issues and financial burdens for patients. Recently, clinical research has demonstrated the potential of helminths and their derivatives as effective therapies for autoimmune disorders. Helminths, being a near-natural immunomodulator, exhibit milder effects than broad-spectrum immunosuppressants and corticosteroids, thereby presenting a promising alternative for the treatment of autoimmune diseases. However, different helminths' therapeutic efficacy and mechanisms and their derivatives in treating autoimmune diseases may vary. Therefore, we aim to review recent clinical advancements in the use of helminths and their derivatives for treating inflammatory bowel disease, multiple sclerosis, and autism spectrum disorder, with a view to offering novel clinical treatment approaches.

T cell infiltration and proliferation in tumor tissues are the main factors that significantly affect the therapeutic outcomes of cancer immunotherapy. Emerging evidence has shown that interferon-gamma (IFNγ) could enhance CXCL9 secretion from macrophages to recruit T cells, but Siglec15 expressed on TAMs can attenuate T cell proliferation. Therefore, targeted regulation of macrophage function could be a promising strategy to enhance cancer immunotherapy via concurrently promoting the infiltration and proliferation of T cells in tumor tissues. We herein developed reduction-responsive nanoparticles (NPs) made with poly (disulfide amide) (PDSA) and lipid-poly (ethylene glycol) (lipid-PEG) for systemic delivery of Siglec15 siRNA (siSiglec15) and IFNγ for enhanced cancer immunotherapy. After intravenous administration, these cargo-loaded could highly accumulate in the tumor tissues and be efficiently internalized by tumor-associated macrophages (TAMs). With the highly concentrated glutathione (GSH) in the cytoplasm to destroy the nanostructure, the loaded IFNγ and siSiglec15 could be rapidly released, which could respectively repolarize macrophage phenotype to enhance CXCL9 secretion for T cell infiltration and silence Siglec15 expression to promote T cell proliferation, leading to significant inhibition of hepatocellular carcinoma (HCC) growth when combining with the immune checkpoint inhibitor. The strategy developed herein could be used as an effective tool to enhance cancer immunotherapy.

ObjectiveTo explore the possible mechanism of Tongdu Xingshen needling method (通督醒神针刺法) on post-stroke cognitive impairment. MethodsSD rats were randomly divided into a normal group (n=12), a sham surgery group (n=12), a model group (n=12), and a electroacupuncture group (n=13). The rats in the model group and electroacupuncture group were subjected to the wire bolus method to establish the rats model with learning memory impairment after cerebral ischaemia-reperfusion. After successful modelling, the rats in the electroacupuncture group were given electroacupuncture interventions at “Shenting (GV 24)” and “Baihui (GV 20)” once a day for 30 minutes for 14 days. The other three groups did not receive other interventions but grasp. A 5-day localisation navigation experiment was conducted on the 9th day of intervention, and a spatial exploration experiment was conducted on the 14th day of intervention to evaluate the learning and memory abilities of the rats. After the spatial exploration experiment, hippocampal tissues were taken from each group of rats, and the changes in the volume of cerebral infarction were observed by TTC staining; the changes in the morphology of pyramidal neurons and the density of dendritic spines in the CA1 area of the hippocampus were observed by Golgi staining; protein immunoblotting was used to detect the relative protein expression of the subunits of the α-amino-3-carboxy-5-methylisoxazole-4-propionic acid (AMPA) receptor including glutamate receptor 1 (GluR1), glutamate receptor 2 (GluR2), glutamate receptor 3 (GluR3) and auxiliary proteins TARPγ2, TARPγ8 in hippocampal tissues of rats in each group; the real-time fluorescence quantitative PCR was used to detect GluR1, GluR2, GluR3 mRNA levels in the hippocampal tissues of rats. ResultsIn the localisation navigation experiment, compared with the normal group and sham surgery group, the escape latency and total distance of rats in the model group were significantly extended (P<0.05) at day 1, 2, 3, 4, and 5; and the escape latency and total distance of rats in the electroacupuncture group tended to be significantly shorter than those in the model group (P<0.05). In the spatial exploration experiment, compared with the normal group and the sham surgery group, the number of rats crossing the platform in the model group was significantly reduced (P<0.05), and the number of crossings of the platform in the electroacupuncture group increased significantly (P<0.05). The results of TTC staining showed that the volume of cerebral infarction increased clearly in the model group compared with the sham surgery group (P<0.05), and apparently decreased in the electroacupuncture group compared with the model group (P<0.05). Golgi staining showed that the number of dendritic branches of pyramidal neurons and dendritic spines in hippocampal CA1 region significantly decreased in the model group compared with the normal group and the sham surgery group (P<0.05). The number of dendritic branches of pyramidal neurons and the density of dendritic spines in hippocampal CA1 region significantly increased in the electroacupuncture group compared with the model group (P<0.05). The protein relative expression levels of GluR1, GluR2, GluR3, TARPγ2 and TARPγ8, and the mRNA levels of GluR1, GluR2 and GluR3 in hippocampus decreased in the model group compared with the normal group and the sham surgery group (P<0.05). The protein relative expression levels of GluR1, GluR2, GluR3, TARPγ2 and TARPγ8, and the mRNA levels of GluR1, GluR2 and GluR3 in hippocampus increased in the electroacupuncture group compared with model group (P<0.05). ConclusionThe Tongdu Xingshen needling method can improve learning memory impairment after cerebral ischaemia-reperfusion, which may be related to up-regulation of the expression of AMPA receptor and their auxiliary protein TARP, and promoting the synaptic plasticity of hippocampal tissues.

Objective To investigate influencing factors of serum small and dense low-density lipoprotein cholesterol (sd LDL-C) levels in patients with chronic diseases in Zhoujiadu community, and to provide a scientific basis for the treatment of sd LDL-C related chronic diseases. Methods A total of 200 patients with common chronic diseases who were admitted to our hospital from November 2017-November 2019 were selected. Basic data including height, weight, past medical history and family history of the patients were collected. Biochemical indicators were measured to understand dietary structure. The influencing factors of serum sd LDL-C were analyzed by multiple stepwise regression. Results The levels of serum sd LDL-C in patients with advanced age, increased BMI, thickened IMT, fatty liver and coronary heart disease were significantly increased (P<0.05). Pearson linear correlation analysis showed that serum sd LDL-C level of patients with chronic diseases was positively correlated with TC, TG, LDL, ALT and AST, and negatively correlated with HDL (P<0.05). Multiple linear regression showed that TG, BMI, IMT, fatty liver, oil heating (frying and frying) and the use of mixed oil were independent risk factors of sd LDL-C level in patients with common chronic diseases, while HDL-C was a protective factor (P<0.05). Conclusion The levels of serum sd LDL-C in patients with common chronic diseases in Zhoujiadu community were correlated with dyslipidemia, BMI, thickening of IMT, fatty liver, oil heating (frying and frying), and use of mixed oil.
