The pancreatic enzyme-II type collagenase digestion method was adopted for primary culture of osteoblasts, inoculation and passage. They were identified by alkaline phosphatase dye-liquor. N-butanol extract fractions from different processed products of Cibotium barometz were prepared. The above osteoblasts were jointly cultured with protocatechuic acid, protocatechuic aldehyde, kojic acid and the mixed control liquid of the above three substances, and their proliferation was detected by CCK-8. Various n-butanol extract fractions from different processed products of C. barometz showed a significant proliferative effect on osteoblasts in the order of the wined > the heated > the salted > the sand-heated and wined system > the alcohol-processed > the steamed > the crude. The q test showed no significant difference among sand-heated, alcohol-processed and steamed C. barometz, no significant difference between heated and salted C. barometz. Various control substances also showed a certain proliferative effect on osteoblasts in the order of the mixed control > protocatechuic aldehyde > protocatechuic acid > kojic acid. The q test showed no significant difference between protocatechuic aldehyde and protocatechuic acid. All of n-butanol extract fractions from different processed products of C. barometz showed a significant effect on osteoblast proliferation, of which wined C. barometz showed the best effect. All of phenolic compounds such as protocatechuic aldehyde, protocatechuic acid and kojic acid showed a significant proliferative effect on osteoblasts.

OBJECTIVE: To explore the effects of Tanreqing injection, a traditional Chinese herbal preparation for clearing heat and resolving phlegm, in treatment of acute exacerbation of chronic obstructive pulmonary disease (AECOPD) by improving airway inflammation and airway mucus hypersecretion. METHODS: A randomized controlled trial (RCT) was designed. Ninety AECOPD patients were randomly divided into Tanreqing group, ambroxol hydrochloride group and control group. The patients in the three groups were all treated with conventional therapy. Furthermore, intravenous drip infusion of 20 ml Tanreqing injection (once daily) and 15 mg ambroxol hydrochloride injection (twice daily) were administered respectively to the patients in the Tanreqing group and ambroxol hydrochloride group. They were all treated for 10 days. Symptom score of traditional Chinese medicine (TCM), plasma concentrations of interleukin-8 (IL-8), IL-10 and neutrophil elastase (NE) were detected before and after treatment. RESULTS: Cough, sputum amount, expectoration, dyspnea, fever, coated tongue and pulse tracings were improved obviously in Tanreqing group (P<0.05), and the effects of Tanreqing on improving cough, sputum amount and expectoration were better than the conventional therapy (P<0.05), while there was no significant difference between Tanreqing group and ambroxol hydrochloride group (P>0.05). Compared with ambroxol hydrochloride group and the control group, the coated tongue was improved obviously in Tanreqing group (P>0.05). After treatment, plasma concentrations of IL-8, IL-10 and NE were decreased in Tanreqing group and ambroxol hydrochloride group (P<0.05), and the levels of IL-8 and IL-10 in the control group were decreased (P<0.05). The change of IL-8 level before and after treatment in Tanreqing group was greater than that in ambroxol hydrochloride group and the control group. The changes of IL-10 and NE levels in ambroxol hydrochloride group were greater than those in Tanreqing group and the control group, while there was no significant difference in the changes of serum levels of IL-8, IL-10 and NE among the three groups (P>0.05). Total response rates in Tanreqing group and ambroxol hydrochloride group were higher than that in the control group (P<0.05), while there was no significant difference in total response rate between Tanreqing group and ambroxol hydrochloride group (P>0.05). There was no significant difference in total response rate among the three groups (P>0.05). CONCLUSION: Tanreqing injection can improve TCM signs and symptoms in AECOPD patients, and the mechanism maybe due to the decrease of serum levels of IL-8 and NE and improvement of IL-10 level.

Single cell "omics" technology enables the capture of genome, transcriptome, proteome and other omics information in a high-throughput and unbiased manner at single-cell resolution, allowing the characterization of the functional state of individual cells to reveal their heterogeneity and differential responses to drug treatment. This technology has wide application in pharmacological research, facilitating drug screening, efficacy evaluation, and mechanistic studies. We envision that, in the field of traditional Chinese medicine (TCM), single cell omics technology can be applied in the identification of active ingredients and drug targets, and elucidation of drug mechanism of action. In this article, we briefly introduce the single cell omics technology - particularly single cell transcriptome sequencing, and review its application in the field of modern drug research. Based on that, we propose the concept of "single cell pharmacology" and articulate how it can be applied to transform the pharmacological research of TCM and promote TCM modernization.

The traditional Chinese medicine (Tripterygium wilfordiiHook.f.,TWH) has been clinically used to treat primary and secondary renal diseases and proteinuria for nearly 40 years.However,there is a rare literature about the effect of triptolide (the main active ingredient of TWH) on the expression of oxidative carbonyl protein (OCP) in diabetic nephropathy (DN).This study aimed to provide experimental evidence for triptolide treatment on DN through its effect on the expression of OCP,in order to investigate the effects of triptolide on the expression of OCP in rats with DN.Sixty SD rats were randomly divided into five groups:control group,high-dose triptolide (Th) group,low-dose triptolide (T1) group,DN model group,and positive control (benazepril) group.The DN model was established using streptozotocin.Urinary protein excretion,fasting blood glucose (FBG),superoxide dismutase (SOD) in renal homogenate,malondialdehyde (MDA) in renal homogenate and renal nitrotyrosine by immunohistochemistry,and the expression of OCP by oxyblotimmune blotting were detected.In the DN model group,rat urinary protein excretion and renal MDA were significantly increased,while renal SOD significantly decreased and nitrotyrosine expression was obviously upregulated in the kidney.After triptolide treatment,24-h urinary protein excretion (61.96±19.00 vs.18.32±4.78 mg/day,P<0.001),renal MDA (8.09±0.79 vs.5.45±0.68 nmol/L,P<0.001),and nitrotyrosine expression were decreased.Furthermore,renal OCP significantly decreased,while renal SOD (82.50±19.10 vs.124.00±20.52 U/L,P<0.001) was elevated.This study revealed that triptolide can down-regulate the expression of OCP in the renal cortex of DN rats.
