ObjectiveTo explore the mechanism of Cervi Cornu Pantotrichumin in the treatment of osteoarthritis by network pharmacology. MethodThe active ingredients and the corresponding targets of Cervi Cornu Pantotrichumin were screened out by a Bioinformatics Analysis Tool of Molecular mechANism of Traditional Chinese Medicine (BATMAN-TCM). The targets related to osteoarthritis were obtained through GeneCards and Online Mendelian Inheritance in Man (OMIM). The targets corresponding to the active ingredients and those related to osteoarthritis were intersected to reveal the common targets, and STRING was adopted to build a protein-protein interaction (PPI) network. DAVID was used for gene ontology (GO) annotation and Kyoto encyclopedia of genes and genomes (KEGG) pathway enrichment on the anti-osteoarthritis targets of Cervi Cornu Pantotrichumin, and R x64 3.6.3 was employed to produce the advanced bubble charts of GO terms and KEGG pathways. Cytoscape 3.7.2 was used to establish the “Chinese medicinal herb-active ingredient-target-signaling pathway” network. In vitro experiments were performed to detect the viability of RAW 264.7 cells exposed to oxidative stress and the tumor necrosis factor (TNF)-α level in RAW 264.7 cells with inflammation under the treatment by Cervi Cornu Pantotrichumin. ResultA total of 20 active ingredients of Cervi Cornu Pantotrichum were obtained, of which ceramide, 6'-O-β-D-glucosylgentiopicroside, cerebroside, oleuropein, sphingomyelin, and cholesterol ferulate did not meet the screening conditions. Therefore, a total of 14 active ingredients were finally screened out, and 303 and 3 093 targets of active ingredients and osteoarthritis were respectively obtained. The two target sets were taken to intersect, which revealed 92 common targets. GO annotation and KEGG pathway enrichment showed that the targets were mainly involved in redox process, positive regulation of RNA polymerase Ⅱ promoter transcription, inflammatory response, protein synthesis, osteoclast differentiation, TNF signaling pathway, signaling pathways in cancer, mammalian target of rapamycin (mTOR) signaling pathway, mitogen-activated protein kinase (MAPK) signaling pathway, and cyclic adenosine monophosphate (cAMP) signaling pathway. The results of in vitro experiments showed that a certain concentration of protein in Cervi Cornu Pantotrichum significantly increased the viability of RAW 264.7 cells exposed to H2O2-induced oxidative damage (P<0.05, P<0.01) and reduced the level of TNF-α in the RAW 264.7 cells experiencing lipopolysaccharide (LPS)-induced inflammation (P<0.05). ConclusionBased on the network pharmacology method, the mechanism of the multi-component, multi-target and multi-pathway treatment of OA by antler antler was explained, and the anti-inflammatory and antioxidant activities of antler antler were confirmed, which provided theoretical guidance and scientific basis for further research on the treatment of OA by antler antler.

This study aimed to investigate the antidepressant effects of total alkaloids of Fibraurea recisa in HT22 cells damaged by corticosterone (CORT) in vitro and in a mouse model of chronic unpredictable mild stress (CUMS) as well as the underlying mechanisms.In cellular experiments,the viability of CORT-damaged HT22 cells was detected using cell counting kit-8 (CCK-8),and the cell apoptosis was detected by Hoechst 33258 staining.In animal experiments,C57BL/6N mice were randomly divided into the control group,model group,low (100 mg·kg~(-1)),medium (200 mg·kg~(-1)) and high (400 mg·kg~(-1))-dose of total alkaloids of F.recisa groups,and positive control group.After 21 days of CUMS exposure,their depressive behaviors were observed in behavioral and Morris water maze tests.The serum levels of 5-hydroxytryptamine (5-HT),dopamine (DA),and norepinephrine (NE) were assessed by ELISA.The expression levels of apoptosis-related proteins Bcl-2,Bax and cleaved caspase-3 in HT22 cells and mouse hippocampus were detected by Western blot.The results suggested that total alkaloids of F.recisa alleviated the damage of HT22 cells induced by CORT in a dose-dependent manner.The Hoechst 33258 staining uncovered that total alkaloids of F.recisa better reduced the blue spots and inhibited cell apoptosis.The results of animal experiments showed that total alkaloids of F.recisa significantly improved the depression-like behaviors of mice and increased the serum levels of 5-HT,DA and NE as compared with those in the model group.The Western blot assays revealed a significant up-regulation of Bcl-2 protein expression,but an obvious reduction in Bax and cleaved caspase-3protein expression in the total alkaloids of F.recisa group.In conclusion,total alkaloids of F.recisa inhibited depression possibly by regulating the apoptosis-related protein expression or elevating the monoamine neurotransmitter levels in the brain.

With the increase of people's health awareness and the progress of medical diagostic technology in recent years, the diagnosis rate of early gastric cancer is increasing year by year. Although radical surgery has good efficacy, how to maximize the preservation of the normal anatomy and function of the stomach and improve the quality of life of patients in the pursuit of radical surgery has become a more important issue in the treatment of early gastric cancer. Under the condition of ensuring radical lymph node dissection, function-preserving gastrectomy can fully preserve gastric function by reducing the resection extent and preserving the pylorus and the vagus nerve, which has advantage of improving quality of life and has great potential in the treatment of early gastric cancer. However, there is no functional evaluation standard for function-preserving gastrectomy at present. Most of the patients are evaluated by quality of life scale, which is relatively subjective. Even though the evaluation of endoscopy, hematology and other objective means can indicate the benefit degree in quality of life brought by functional reconstruction, the evidence level is limited. Therefore, this paper discusses the research status of function-preserving gastrectomy evaluation, postoperative complications, postoperative nutritional status, auxiliary examination and other items in the evaluation of gastric function, and analyzes the prospects of research direction in this field.

Methods A total of 234 patients with hyperparathyroidism that confirmed by operation and pathology were collected from September 2017 to September 2019. Results The median PTH levels in PHPT group and SHPT group were 210.93 (122.60~529.20) pg/ml and 1842.50 (1342.50~2345.00) pg/ml, respectively. There was significant difference between the two groups (Z = − 10.83, P = 0.000). SHPT group was significantly higher than that in PHPT group. The median of Ca level of PHPT group and SHPT group was 2.86 (2.65~3.15) mmol/L and 2.43 (2.32~2.58) mmol/L, respectively. There was significant difference between the two groups (Z = −7.52, P = 0.000). The level of Ca in PHPT group was significantly higher than that in SHPT group. The median of P level in PHPT group and SHPT group was 0.80 (0.64~1.03) mmol/L and 2.26 (1.97~2.63) mmol/L respectively. There was significant difference between the two groups (Z = − 10.15, P = 0.000), and the PHPT group was significantly lower than the SHPT group. The age, gender, PTH and Ca and P value were taken as independent variables, and the results of MIBI imaging were used as dependent for logistic regression analysis. After screening, the influencing factor of PHPT group was PTH value (OR: 1.012, 95% CI: 1.002~1.023), and correlation analysis showed that r = 0.60 (P = 0.000). No related factors were found in SHPT group. ROC curves of 99Tcm-MIBI imaging results in PHPT group were drawn, corresponding to the areas under the maximum curve of 0.91, and the calculated cutoff value was 113.1 pg/mL. simple scatter plot of Ca value, P value and PTH value was drawn in PHPT group and SHPT group, and correlation analysis was performed. In PHPT group, Ca value and PTH value had moderate correlation (r = 0.64, P = 0.000), P value and PTH value had low correlation (r = − 0.28, P = 0.032); in SHPT group: Ca value and PTH value had low correlation (r = 0.17, P = 0.03), P value and PTH value had no correlation (P = 0.15). Conclusion The serum PTH level of PHPT was moderately correlated with MIBI imaging results. The higher the serum PTH level, the higher the positive rate of MIBI imaging, and the corresponding cutoff value of MIBI imaging was 113.1 pg/mL. There was a moderate correlation between serum Ca level and serum PTH level in PHPT, while in SHPT group low correlation between serum Ca level and serum PTH level.

Ge Gen Decoction (GGD), a Traditional Chinese Medicine prescription, is mainly used to treat infectious respiratory diseases and can relieve the symptoms of influenza A virus (IAV) infection. However, the underlying mechanism of GGD against IAV infection remains unclear. In this study, we found that GGD had moderate anti-IAV activity in vitro. GGD was more effective when given before the viral infection and targeted the viral attachment and replication stages rather than the internalization stage. In vivo, GGD treatment reduced thevirus titers of lung tissue significantly and improved the survival rate, lung index, and pulmonary histopathological changes in H1N1-infected mice. We observed the changes in several key immuno-related indexes in GGD administrated H1N1-infected mice with anti-IAV drug oseltamivir phosphate as the control. GGD treatment decreased the expression of TNF-α and improved Th1/Th2 immune balance to reduce the excessive immune response in H1N1-infected mice. Besides, the expression of the toll-like receptor 7 signaling pathway in H1N1-infected mice decreased after GGD treatment. Our results showed that GGD has anti-IAV activity and can modulate the immune system to relieve lung inflammation.

Scutellariae baicalensis is one of the most important traditional Chinese medicinal herbs, mainly distributed in Shandong and Hebei provinces. It has significant pharmacological effects such as antimicrobial activity, anti-inflammatory and antioxidation. Baicalin is one of its main effective components. However, baicalin's low bioavailability has restricted its clinical application. In recent decades, extensive studies have been carried out on the metabolism of baicalin at home and abroad. In order to provide scientific references for baicalin's further studies, this paper would not only review the advances in pharmacokinetics research of baicalin and Chinese herbal preparations containing baicalin, but also make a summary on research status of baicalin.

Decoction is one of the most commonly used dosage forms of traditional Chinese medicine. The stability of chemical constituents in decoction is closely related to the clinical efficacy and safety. There were few reports about the influence of metal ions in the stability of chemical constituents in traditional Chinese medicine. However, there is no evidence that metal ions in decoction water need to be controlled. In this study, 2,3,5,4'-tetrahydroxy stilbene-2-O-β-D-glucoside (THSG), one of the main constituents in Polygoni Multiflori Radix was studied. Ordinary tap water, deionized water, and water containing different metal ions were used to investigate and compare the influence on THSG. The results showed that after storage in a dark place at the room temperature for 10 days, the degradation of THSG was 7% in deionized water, while undetectable in tap water. The content of THSG could be decreased by different kinds of metal ions, and the effect was concentration-dependent. Moreover, Fe3+ and Fe2+ showed the greatest influence at the same concentration; and our study has shown that THSG decreased more than 98% in Fe and Fe2+ solutions at 500 ppm concentration. In the same time we found out p-hydroxybenzaldehyde (molecular weight: 122.036 7) and 2,3,5-trihydroxybenzaldehyde-2-O-glycoside (molecular weight: 316.079 4) were the main degradation products of THSG in tap water and water containing Cu2+, Ca2+, Zn2+, Mg2+ and Al3+. The product of THSG dimer with a water molecule was found in water containing Fe3+ and Fe2+. The above results showed that the metal ions in water could significantly influence the stability of THSG in water, indicating that the clinical efficacy and safety of decoction would be affected if the metal ions in water were not under control. It's suggested that deionized water should be used in the preparation of decoction containing Polygoni Multiflori Radix in the clinic to avoid degradation of THSG. Meanwhile, decoction prepared by tap water should be taken by patients in a short time. Our investigation provides important information and reference about the influence of metal ions on the stability of decoctions in other traditional Chinese medicine that have unstable groups such as hydroxyls and unsaturated bonds, etc.
