This study was aimed to investigate effect on the expression of cell inflammatory factor IL-1α, IL-1β and IL-6 of modified San-Jia-San (SJS) decoction on cultured hippocampal neurons injury induced by β-amyloid 25-35 protein (Aβ25-35). Primary cultured hippocampal neurons were divided into the normal group, model group, huperzine A group, low-dose SJS group, middle-dose SJS group, and high-dose SJS group. After selective culture for 7~10 days and the absorption of culture fluid, the blank culture fluid, normal cerebrospinal fluid (normal saline group), huperzine A cerebrospinal fluid, and low-, middle- and high-dose SJS cerebrospinal fluid were added, respectively. The culture fluid was added up to an equivalent medium. The incubation was 2 h under the temperature of 37℃. Ex-cept the normal group, Aβ25-35 dealt with aging (the final concentration was 5 μmol/L) was added to other groups to establish AD cell model. An equivalent amount of culture fluid was added to the normal group. After 24 h of incuba-tion, the cell culture supernatant was collected. Enzyme-linked immunosorbent assay (ELISA) was used in the content detection of IL-1α, IL-1β and IL-6. The results showed that modified SJS decoction can decrease the content of IL-1α, IL-1β and IL-6 in the cell culture supernatant. It was concluded that the modified SJS decoction can effectively inhibit the expression of cell inflammatory factor IL-1α, IL-1β and IL-6. It had certain anti-inflammatory effect to protect hippocampal neurons.

OBJECTIVE To study the protective effects of ligustrazine-scutellarein twin drug ST-11 on rat adrenal medullary pheochromocytoma PC12 cell injury induced by oxygen-glucose deprivation/reperfusion (OGD/R) and its mechanism. METHODS PC12 cells were divided into blank group, model group, nimodipine group (positive control, 5 μmol/L) and different concentration groups of ST-11 (5, 10, 20 μmol/L). After 24 hours of pre-administration intervention, all the other groups except the blank group were cultured in glucose-free DMEM culture medium containing 10 mmol/L Na2S2O4 for 4 hours with glucose deficiency and hypoxia. After 4 hours of glucose and oxygen re-introduction, the survival rate of cells in each group, the contents of lactate dehydrogenase (LDH), catalase (CAT), glutathione (GSH), malondialdehyde (MDA) and superoxide dismutase (SOD) in cell supernatant, apoptosis rate, the levels of reactive oxygen species (ROS) and mitochondrial membrane potential (MMP), the protein expressions of B-cell lymphoma 2 related X protein (Bax), B-cell lymphoma 2 (Bcl-2) and caspase-3 were all detected in each group. RESULTS Compared with blank group, the cell survival rate, the contents of CAT, GSH and SOD in cell supernatant, MMP level, relative expression of Bcl-2 and Bcl-2/Bax ratio in model group decreased significantly (P<0.05), while the contents of LDH and MDA, ROS level, apoptosis rate, relative expressions of Bax and caspase-3 were significantly increased (P<0.05). Compared with model group, above indexes of ST-11 groups (except for the protein expression of caspase-3 in 5 μmol/L ST-11 group) were reversed signifi-cantly (P<0.05). CONCLUSIONS ST-11 has a certain protec-tive effect on OGD/R-injured PC12 cells, and its effects may be related to reduction of oxidative stress and inhibition of cell apoptosis.

Non-alcoholic fatty liver disease is a common chronic liver disease in clinical practice. In recent years, with increasing social attention to the health of women and the elderly, the prevention and treatment of non-alcoholic fatty liver disease after menopause has increasingly become a research hotspot in metabolic diseases. This study explores the pathogenesis and treatment method of non-alcoholic fatty liver disease in postmenopausal women based on the theory of "deficient qi and stagnation" and combined with the physiological and pathological characteristics of postmenopausal women and the Western medicine understanding of non-alcoholic fatty liver disease. We believe that the pathogenesis of non-alcoholic fatty liver disease in postmenopausal women is rooted in the "deficient qi" caused by depletion of liver and kidney essence and blood. The imbalance between the physical and functional aspects of the liver due to this "deficient qi" is the primary factor, while the "stagnation" of phlegm and blood stasis is the manifestation. Furthermore, the "deficient qi" and "stagnation" reinforce each other, with the deficiency leading to stagnation and stagnation exacerbating the deficiency, thus accelerating the progression of the disease. The treatment approach should be one that combines nourishing deficiency and resolving stagnation, addressing both root cause and maifestations. Given the female characteristic of "the liver as the innate organ" and the post-menopausal physiological state of "gradual decline of kidney essence", it is important to focus on nourishing the liver and kidneys, nurturing the liver′s physical body while maintaining its function, and also promoting the circulation of qi, resolving phlegm, and invigorating blood circulation to remove blood stasis. This approach aims to reduce the accumulation of lipids in the liver, offering a new perspective and approach for the treatment of non-alcoholic fatty liver disease in post-menopausal women with traditional Chinese medicine.

OBJECTIVE: To investigate inhibitory effects of protopine on the proliferation of human hepatic stellate cells HSC-LX2 and to explore its mechanism preliminarily. METHODS: MTT assay was used to detect the effects of 25, 50, 100, 200, 400 and 500 μmol/L protopine on the proliferation of HSC-LX2 cells. The inhibitory effect of cell proliferation was calculated. HSC-LX2 cells were divided into control group (1640 medium containing 5% fetal bovine serum), protopine low-concentration, medium-concentration and high-concentration groups (100, 200, 400 μmol/L). After treated for 24 h. The apoptotic rate of the cells was detected by flow cytometry. RT-PCR was used to determine the mRNA expression of α-SMA, Collagen Ⅰ, Collagen Ⅲ, MMP-2 and TIMP-1 in cells. The protein expressions of α-SMA, Collagen Ⅰ, Collagen Ⅲ and MMP-2 were detected by Western blot. RESULTS: The inhibitory rates of 25, 50, 100, 200, 400 and 500 μmol/L protopine on proliferation HSC-LX2 cells were 0, 6.9%, 18.7%, 34.2%, 48.9%, 53.9%, respectively. Compared with control group, mRNA expression of Collagen Ⅰ, TIMP-1 and protein expression of α-SMA were decreased significantly in protopine low-concentration, medium-concentration and high-concentration groups, while protein expression of MMP- 2 was increased significantly, with statistical significance (P<0.05 or P<0.01). Apoptotic rate of HSC-LX2 cells and mRNA expression of MMP-2 were increased significantly in protopine medium-concentration and high-concentration groups, mRNA expression of α-SMA and Collagen Ⅲ, protein expression of Collagen Ⅰ and Collagen Ⅲ were decreased significantly, with statistical significance (P<0.05 or P<0.01). CONCLUSIONS: Protopine can induce the apoptosis of HSC-LX2 cells and inhibit their cell proliferation, and reduce the expression of a-SMA, Collagen Ⅰ, Collagen Ⅲ and TIMP-1, and increase the expression of MMP-2.
