ABSTRACT

In the digital transformation of Chinese pharmaceutical industry, how to efficiently govern and analyze industrial data and excavate the valuable information contained therein to guide the production of drug products has always been a research hotspot and application difficulty. Generally, the Chinese pharmaceutical technique is relatively extensive, and the consistency of drug quality needs to be improved. To address this problem, we proposed an optimization method combining advanced calculation tools(e.g., Bayesian network, convolutional neural network, and Pareto multi-objective optimization algorithm) with lean six sigma tools(e.g., Shewhart control chart and process performance index) to dig deeply into historical industrial data and guide the continuous improvement of pharmaceutical processes. Further, we employed this strategy to optimize the manufacturing process of sporoderm-removal Ganoderma lucidum spore powder. After optimization, we preliminarily obtained the possible interval combination of critical parameters to ensure the P_(pk) values of the critical quality properties including moisture, fineness, crude polysaccharide, and total triterpenes of the sporoderm-removal G. lucidum spore powder to be no less than 1.33. The results indicate that the proposed strategy has an industrial application value.

ABSTRACT

ObjectiveTo compare the effect of different solvent extracts of spore powder and fruiting body of Lasiosphaera Calvatia on fibroblasts and wound healing of full-thickness skin defect, in order to screen the optimal medication part of Lasiosphaera Calvatia. MethodThe effect of water extract and alcohol extract of spore powder and fruiting body on cell proliferation and cell migration of mouse skin fibroblasts (MSF) were examined in vitro. Cell proliferation and activity test (CCK-8) method was used for cell proliferation, scratch assay was used for cell migration, flow cytometry was conducted to explore cell cycle, enzyme-linked immunosorbent assay (ELISA) was used to determine the production of collagen Ⅰ and Ⅲ. At the same time, a full-thickness skin defect wound model was established to investigate the therapeutic effect of different solvent extracts of spore powder. Ultraviolet-visible spectrophotometry was used to measure the contents of index components in different solvent extracts. ResultThe water extract of spore powder and fruiting body had certain cytotoxicity, while the alcohol extract could promote proliferation, migration and production of collagen Ⅰ and Ⅲ of MSF, and the effect of spore powder was significantly higher than that of fruiting body. When the concentration was 10 mg·L-1, the cell proliferation rate of alcohol extract of spore powder was as high as (159.22±15.95)%, and could promote MSF from the G0/G1 phase to S phase and G2/M phase with an increased proliferation index. The alcohol extract also promoted the migration of fibroblasts, secreted collagen Ⅰ and Ⅲ. On in vivo model, the alcohol extract of spore powder significantly accelerated wound healing on mice, effectively promoted the complete epithelialization of wound tissue, and generated new collagen fiber. The results of determination showed that the contents of polyphenols and flavonoids in the alcohol extract were higher than the alcohol extract of fruiting body. ConclusionThe alcohol extract of spore powder in Lasiosphaera Calvatia has active components in the treatment of wounds with good development prospect, and the medicinal components may be polyphenols and flavonoids.

ABSTRACT

OBJECTIVE@#Ganoderma lucidum spore (GLS) is gaining recognition as a medicinal part of G. lucidum and has been reported to possess various pharmacological properties, such as antitumor activity. In this work, wall-broken GLS powder (BGLSP) and wall-removed GLS powder (RGLSP), two kinds of GLS powder with different manufacturing techniques, were compared in terms of contents of active constituents and in vivo and in vitro antitumor effects.@*METHODS@#The ultraviolet and visible spectrophotometry method was used to determine the contents of polysaccharides and total triterpenoids in BGLSP and RGLSP. Seventeen individual triterpenoids were further quantified using ultra-high-performance liquid chromatography and quantitative analysis of multi-components by single marker. The antitumor effects of BGLSP and RGLSP were evaluated using in vitro cell viability assay against human gastric carcinoma SGC-7901, lung carcinoma A549 and lymphoma Ramos and further validated by in vivo zebrafish xenograft models with transplanted SGC-7901, A549 and Ramos.@*RESULTS@#The results showed that the contents of polysaccharides, total triterpenoids and individual triterpenoids of RGLSP were significantly higher than those of BGLSP. Although both BGLSP and RGLSP inhibited the three tumor cell lines in vitro in a dose-dependent manner, the inhibitory effects of RGLSP were much better than those of BGLSP. In the in vivo zebrafish assay, RGLSP exhibited more potent inhibitory activities against tumors transplanted into the zebrafish compared with BGLSP, and the inhibition rates of RGLSP reached approximately 78%, 31% and 83% on SGC-7901, A549 and Ramos, respectively.@*CONCLUSION@#The results indicated that the antitumor effects of GLS were positively correlated with the contents of the polysaccharides and triterpenoids and demonstrated that the wall-removing manufacturing technique could significantly improve the levels of active constituents, and thereby enhance the antitumor activity.

ABSTRACT

Objective To observe the effect of Ganoderma lucidum spore powder on sugar tolerance and intestinal flora of diabetes rats induced by streptozotocin (STZ). Methods The diabetes model rats (divided into 2 groups: the therapy group and the control) were intragastric administration with equal volume of Ganoderma lucidum spore powder and distilled water for 10 weeks, respectively. Then the blood glucose level and intestinal flora amount were tested. Results The abnormal sugar tolerance of therapy group rats returned to normal and the amount of Bacillus bifidus in intestinal flora also recovered. There were significant differences compared with control. Conclusion Canoderma lucidum spore powder can decrease blood sugar level and adjusts intestinal flora amount of experiment rats.

ABSTRACT

[Objective] To explore Ganoderma spore powder on severe acute pancreatitis(SAP) for the role. [Methods] Retrograde cholangiopancreatography injection of 5% sodium taurocholate caused SAP model; SD rats were randomly divided into sham surgery group, model group, octreotide treatment group, Ganoderma spore powder treatment group and Ganoderma spore powder octreotide in the treatment group; After hours of the serum amylase levels in the rats killed after 7 days administration, the level of plasma endotoxin and pancreas for histopathologic examination.[Results]SAP results in serum amylase concentration and plasma endotoxin were significantly increased, with serious pancreatic tissue damage. Treatment found the effect of Ganoderma spore powder combined with octreotide better, and the other treatment groups difference was significant(P
