Objective: To explore the mechanism of the Chinese medicine Cigu Xiaozhi prescription (, CGXZ) in the treatment of the non-alcoholic fatty liver disease (NAFLD) by detoxification and phlegm-reducing, the effect of CGXZ prescription on ceramide-mediated lipid apoptosis in Hep G2 cells with NAFLD.
Methods: The experiment was randomly divided into 6 groups: normal control group, model group, CGXZ prescription medicated serum high, medium, and low dose groups, and pioglitazone positive control group. Using 500 μmol/L free fatty acid (FFA) mixture to induce Hep G2 cells to establish NAFLD cell model, respectively, with 2%, 4%, and 6% concentration of CGXZ prescription medicated serum intervention for 24 h. The changes in organelles and lipid droplet accumulation were observed under the electron microscope. Furthermore, TdT-mediated dUTP Nick-End Labeling method was used to assay hepatocyte apoptosis; Biochemical determination of glutamic-pyruvic transaminase, glutamic oxalacetic transaminase, triglycerides, and FFA levels in Hep G2 cells; the content of ceramide was determined by high-performance thin-layer chromatography. Finally, Western Blot and quantitative real-time polymerase chain reaction (qRT-PCR) were used to determine the protein and gene expression levels, such as inducible nitric oxide synthase (iNOS), nuclear factor κB (NF-κB), B cell lymphoma 2 (Bcl-2) and Bcl-2-associated X (Bax).
Results: Under the electron microscope, the cells in the model group showed moderate-to-severe steatosis, and apoptotic bodies could be seen. The model group had greater improvements in the apoptosis rate (P < 0.01), and the levels of ceramide C2 and FFA in the cytoplasm (P < 0.01) than the normal control group. The protein expressions of NF-κB, iNOS, and Bax were significantly up-regulated (P < 0.05), while the Bcl-2 had no significant change (P > 0.05). Compared with the model group, the levels of ceramide C2 and FFA (P < 0.01), the protein expressions of NF-κB, iNOS, and Bax (P < 0.05) in the CGXZ prescription treatment group and pioglitazone positive control group were significantly decreased; Only the Bcl-2 protein was significantly up-regulated in the high-dose Chinese medicine group (P < 0.05). The down-regulation of Bax mRNA expression in each Chinese medicine treatment group was significantly better than in the pioglitazone positive control group (P < 0.01).
Conclusions: The CGXZ prescription, formulated with the method of detoxification and phlegm, can inhibit lipoapoptosis in the NAFLD cell model by down-regulating the levels of ceramide C2 and FFA, which may be achieved by regulating ceramide/iNOS/NF-κB signaling pathway.

Objective: To evaluate the efficacy and safety of Qingchang suppository (, QCS), a preparation of Chinese herbal medicine, in the induction of remission in patients with mild-to-moderate ulcerative proctitis (UP).
Methods: We performed a multicenter, prospective, randomized, parallel-controlled trial to evaluate the efficacy of QCS induction therapy in 140 adult patients with mild-to-moderate UP and TCM syndrome of dampness-heat in large intestine. The patients were randomized to receive QCS (study group) or Salicylazosulfapyridine (SASP) suppository (control group) one piece each time, twice a day, per anum for 12 weeks. Mayo score and main symptoms score were evaluated at weeks 0, 2, 4, 8 and 12, rectosigmoidscopy was taken at weeks 0, 4, 8 and 12, Geboes score, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) and safety indexes were assessed at weeks 0 and 12. The primary efficacy endpoint is clinical remission rate, the secondary efficacy endpoints are clinical response rate, mucosa healing rate, Geboes score, the remission rates of the main symptoms, the median day to the remission of the symptom, etc. RESULTS: There were no statistical difference in the clinical remission rates, the clinical response rates, the mucosa healing rates, Geboes score, ESR and CRP between the two groups. The remission rates of tenesmus and anal burning sensation of the study group were significantly higher than those of the control group (76.5% vs 25.0%, P = 0.009; 74.51% vs 29.63%, P = 0.003). The median day to the remission of purulent bloody stool of the study group was significantly less than that of control group [11 (1, 64) vs 19 (2, 67), P = 0.007]. The patients receiving QCS had a significantly higher mucosa healing rate at week 4 than the patients receiving SASP suppository (71.42% vs 52.85%, P = 0.023). No adverse event occurred in the study group while the adverse events incidence of the control group was 5.7% (P = 0.049).
Conclusions: QCS could induce the remission of UP as effectively and safely as SASP suppository, and was superior to SASP suppository in relieving the symptoms of tenesmus, anal burning sensation and purulent bloody stool and the time to reach mucosa healing.

Objective: To investigate the effect of Taohong Siwu decoction (, TSD) on atherosclerosis in rats as well as investigate the underlying mechanism based on molecular docking.
Methods: Sixty healthy male Sprague-Dawley rats were randomly divided into 6 groups with 10 rats in each group: control group, model group, atorvastatin group (AT, 2.0 mg/kg), and TSD groups (20, 10, 5 g/kg) after 7 d of acclimation. The model of atherosclerosis was successfully established except the control group by high fat diet (HFD) and vitamin D2. Biochemical analyzers were used to detect the levels of triglyceride (TG), total cholestero (TC), low density lipoprotein-cholesterol (LDL-C) and high density lipid-cholesterol (HDL-C) in blood lipid. The levels of tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6) and interleukin-1β (IL-1β) were determined by enzyme-linked immunosorbent assay. Sudan IV staining and Hematoxylin and eosin staining (HE staining) were performed to observe the pathological changes in aortic tissue. Molecular docking technology was used to predict the best matching between the main components of TSD and the target proteins. The expression of target proteins was further detected by quantitative real time polymerase chain reaction (qRT-PCR) and Western blot analysis.
Results: The results showed that TSD restricted atherosclerosis development and decreased the inflammatory cytokines in plasma. Molecular docking results predicted that the main components of TSD showed a strong binding ability with toll-like receptor (TLR4), myeloid differentiation primary response protein 88 (MyD88), and nuclear factor kappa-B (NF-κB). The results of qRT-PCR and Western blot analysis showed that the mRNA and protein expressions of TLR4, MyD88 and NF-κB p65 in the aorta were reduced in atorvastatin group and TSD group.
Conclusions: TSD can ameliorate atherosclerosis in rats, and the underlying mechanism is supposed be related to the suppression of inflammatory response by regulating TLR4/MyD88/NF-κB signal pathway.

Objective: To elucidate the mechanism of the nourishing Yin and purging fire Chinese herbal mixture (NYPF) in delaying light-induced premature puberty in rats.
Methods: Twenty-one days old female Sprague-Dawley rats were randomly assigned to normal group (N), long light exposure group (L), NYPF and normal saline group (NS). Rats in the L, NYPF and NS groups were exposed to 16 h: 350 lux light/8 h: dark, while rats in the N group were exposed to 12 h: 50 lux light/12 h: dark. NYPF and normal saline was administered to the rats in the NYPF group or NS group, respectively, from day 21. Five rats in every group were sacrificed at 9 p.m. on day 28 (P28), on the day when rat's vulva opened in the L group (L-VO), on the day when the first estrous interphase occurred in rats of L group (L-E1), and on the day when the second estrous interphase occurred in rats of L group (L-E2), respectively.
Resulits: On day 34, all rats in the L group, 80% of rats in the NS group, 40% of rats in the N group, and 20% of rats in the NYPF group showed complete opening of the vulva. At P28, mRNA level of hypothalamic kisspeptin (Kiss-1) in the L group was significantly higher than that in the N group (P < 0.05). The rats in the L and NS groups had significantly lower hypothalamic arginine-phenylalanine-amide (RFamide)-related peptide 3 (RFRP-3) mRNA levels than those in the N group (P < 0.05), whereas RFRP-3 mRNA level was significantly higher in the NYPF group than that in the L group (P < 0.05). At L-VO, the ovarian index of the L and NS groups was significantly higher than that of the N group (P < 0.05) and estradiol (E2) level of the NYPF group was significantly lower than that of the N and NS groups (P < 0.05); hypothalamic Kiss-1 mRNA level in the L and NS groups was significantly higher than that in the N and NYPF groups (P < 0.05), whereas hypothalamic RFRP-3 mRNA level in the L, NYPF, and NS groups was significantly lower than that in the N group (P < 0.05). At L-E1, E2 level of the L and NS groups was significantly higher than that of the N group (P < 0.01), whereas it was significantly lower in the NYPF group than that of the N, L, and NS groups (P < 0.01), and serum luteinizing hormone level of the L and NS groups was significantly higher than that of the N group (P < 0.05); levels of serum melatonin and ovarian melatonin receptor 1 (MT-1) mRNA in the L, NYPF, and NS groups were significantly lower than those in the N group (P < 0.05). At L-E2, the uterine organ index of the NYPF group was significantly lower than that of the L group (P < 0.05); and ovarian MT-1 mRNA level of the L and NS groups was significantly lower than that in the N group (P < 0.05).

Objective: To study the effect of Jiangzhi Xiaoban tablet (, JZXB) on toll-like receptor 4 (TLR4)/nuclear factor-kappa B (NF-κB)/Nod-like receptor protein 3 (NLRP3) signaling pathway expression in atherosclerosis (AS) mice by establishing a mouse model of AS, and to explore its mechanism of prevention and treatment of AS.
Methods: Sixty-four male C57BL/6J mice were randomly divided into two groups, 12 in the normal control group and 52 in the model group (MOD). Seven weeks later, two mice in each of the above two groups were randomly sacrificed, and the whole aortic tissue of the mice was taken out for hematoxylin-eosin staining. After successful modeling, 50 mice in the modeling group were randomly divided into 5 groups: MOD, atorvastatin group (ATO), low-dose group of JZXB (JZXB-L), middle-dose group of JZXB (JZXB-M), and high-dose group of JZXB (JZXB-H), 10 mice in each group. The mice in each group were killed after 6 weeks of preventive administration. HE staining was used to observe the pathological changes of aorta in AS mice. The levels of serum triglyceride (TG), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C) and high-density lipoprotein cholesterol (HDL-C) were detected by automatic biochemical analyzer. The levels of inflammatory factor interleukin-1β (IL-1β) were detected by enzyme linked immunosorbent assay. The expression of TLR4, NF-κB and NLRP3 proteins in aortic tissue was detected by immunohistochemistry.
Results: Compared with the MOD, the levels of serum TC, TG and LDL-C in the JZXB-H and ATO were significantly decreased, while the level of HDL-C was significantly increased. The levels of serum TG, LDL-C in the JZXB-M were significantly decreased, and the level of HDL-C was significantly increased. Compared with the MOD, the levels of IL-1β were significantly decreased, aortic lesions were significantly improved, and the expression of TLR4, NF-κB, and NLRP3 proteins in the aortic tissue was significantly decreased in the JZXB-H, JZXB-M, and ATO.
Conclusion: JZXB has inhibitory effect on atherosclerosis in mice, and its mechanism may be through regulating the TLR4/NF-κB/NLRP3 signaling pathway and reducing the inflammatory response, so as to play a role in inhibiting atherosclerosis.
研究目的通过建立动脉粥样硬化(AS)小鼠模型,研究江浙夏枯草片(JZXB)对动脉粥样硬化(AS)小鼠体内toll样受体4(TLR4)/核因子-kappa B(NF-κB)/Nod样受体蛋白3(NLRP3)信号通路表达的影响,并探讨其防治AS的机制:将64只雄性C57BL/6J小鼠随机分为两组,正常对照组12只,模型组(MOD)52只。七周后,随机处死上述两组各两只小鼠,取出小鼠的整个主动脉组织进行苏木精-伊红染色。建模成功后,将建模组的 50 只小鼠随机分为 5 组:MOD组、阿托伐他汀组(ATO)、JZXB低剂量组(JZXB-L)、JZXB中剂量组(JZXB-M)、JZXB高剂量组(JZXB-H),每组10只。各组小鼠在预防性给药 6 周后处死。HE 染色观察 AS 小鼠主动脉的病理变化。用自动生化分析仪检测血清甘油三酯(TG)、总胆固醇(TC)、低密度脂蛋白胆固醇(LDL-C)和高密度脂蛋白胆固醇(HDL-C)的水平。酶联免疫吸附试验检测了炎症因子白细胞介素-1β(IL-1β)的水平。免疫组化法检测了主动脉组织中 TLR4、NF-κB 和 NLRP3 蛋白的表达:结果:与 MOD 相比,JZXB-H 和 ATO 的血清 TC、TG 和 LDL-C 水平显著降低,而 HDL-C 水平显著升高。JZXB-M的血清TG、LDL-C水平明显下降,HDL-C水平明显上升。与MOD相比,JZXB-H、JZXB-M和ATO的IL-1β水平明显降低,主动脉病变明显改善,主动脉组织中TLR4、NF-κB和NLRP3蛋白的表达明显减少:结论:JZXB对小鼠动脉粥样硬化有抑制作用,其机制可能是通过调节TLR4/NF-κB/NLRP3信号通路,减轻炎症反应,从而起到抑制动脉粥样硬化的作用。

Objective: To investigate the effect of Neferine (Nef) on diabetic nephropathy (DN) and to explore the mechanism of Nef in DN based on miRNA regulation theory.
Methods: A DN mouse model was constructed and treated with Nef. Serum creatinine (Crea), blood urea (UREA) and urinary albumin were measured in mice by kits, and renal histopathological changes and fibrosis were observed by hematoxylin-eosin staining and Masson staining. Renal tissue superoxide dismutase (SOD), malondialdehyde (MDA) and glutathione peroxidase (GSH-Px) activities were measured by enzyme-linked immunosorbent assay (ELISA). Western blotting was used to detect the expression of nuclear factor E2-related factor 2 (Nrf2)/ heme oxygenase 1 (HO-1) signaling pathway-related proteins in kidney tissues. Quantitative reverse transcription-polymerase chain reaction (qRT-PCR) was used to detect the expression of miR-17-5p in kidney tissues. Subsequently, a DN in vitro model was constructed by high glucose culture of human mesangial cells (HMCs), cells were transfected with miR-17-5p mimic and/or treated with Nef, and we used qRT-PCR to detect cellular miR-17 expression, flow cytometry to detect apoptosis, ELISAs to detect cellular SOD, MDA, and GSH-Px activities, Western blots to detect Nrf2/HO-1 signaling pathway-related protein expression, and dual luciferase reporter gene assays to verify the targeting relationship between Nrf2 and miR-17-5p.
Results: Administration of Nef significantly reduced the levels of blood glucose, Crea, and UREA and the expression of miR-17-5p, improved renal histopathology and fibrosis, significantly reduced MDA levels, elevated SOD and GSH-Px activities, and activated Nrf2 expression in kidney tissues from mice with DN. Nrf2 is a post-transcriptional target of miR-17-5p. In HMCs transfected with miR-17-5p mimics, the mRNA and protein levels of Nrf2 were significantly suppressed. Furthermore, miR-17-5p overexpression and Nef intervention resulted in a significant increase in high glucose-induced apoptosis and MDA levels in HMCs and a significant decrease in the protein expression of HO-1 and Nrf2.
Conclusion: Collectively, these results indicate that Nef has an ameliorative effect on DN, and the mechanism may be through the miR-17-5p/Nrf2 pathway.

Objective: To evaluate the efficacy of electroacupuncture (EA) intervention on myocardial protection and postoperative rehabilitation in patients undergoing cardiac surgery with cardiopulmonary bypass (CPB).
Methods: Eight databases, including PubMed, Embase, the Cochrane Library, Web of Science, Chinese BioMedical Literature Database, China National Knowledge Infrastructure Database, Wanfang Data, China Science and Technology Journal Database, and two clinical trial registries, were searched. All randomized controlled trials (RCTs) related to EA intervention in cardiac surgery with CPB were collected. Based on the inclusion and exclusion criteria, two researchers independently screened articles and extracted data. After the quality evaluation, RevMan 5.3 software was used for analysis.
Results: Fourteen RCTs involving 836 patients were included. Compared with the control treatment, EA significantly increased the incidence of cardiac automatic rebeat after aortic unclamping [relative risk (RR) = 1.15, 95% confidence interval (CI) (1.01, 1.31), P < 0.05; moderate]. Twenty-four hours after aortic unclamping, EA significantly increased the superoxide dismutase [standardized mean difference (SMD) = 0.96, 95% CI(0.32, 1.61), P < 0.05; low], and interleukin (IL)-2 [SMD = 1.33, 95% CI(0.19, 2.47), P < 0.05; very low] expression levels and decreased the malondialdehyde [SMD =-1.62, 95% CI(-2.15, -1.09), P < 0.05; moderate], tumour necrosis factor-α [SMD = -1.28, 95% CI(-2.37, -0.19), P < 0.05; moderate], and cardiac troponin I [SMD = -1.09, 95% CI(-1.85, -0.32), P < 0.05; low] expression levels as well as the inotrope scores [SMD = -0.77, 95% CI(-1.22, -0.31), P < 0.05; high]. There was no difference in IL-6 and IL-10 expression levels. The amount of intraoperative sedative [SMD = -0.31, 95% CI(-0.54, -0.09), P < 0.05; moderate] and opioid analgesic [SMD = -0.96, 95% CI(-1.53, -0.38), P < 0.05; low] medication was significantly lower in the EA group than in the control group. Moreover, the postoperative tracheal intubation time [SMD = -0.92, 95% CI(-1.40, -0.45), P < 0.05; low] and intensive care unit stay [SMD = -1.71, 95% CI(-3.06, -0.36), P < 0.05; low] were significantly shorter in the EA group than in the control group. There were no differences in the time to get out of bed for the first time, total days of antibiotic use after surgery, or postoperative hospital stay. No adverse reactions related to EA were reported in any of the included studies.
Conclusions: In cardiac surgery with CPB, EA may be a safe and effective strategy to reduce myocardial ischaemia-reperfusion injury and speed up the recovery of patients after surgery. These findin

Objective: To prepare aloe-emodin solid dispersion (AE-SD) and determine the metabolic process of AE and AE-SD in vivo.
Methods: AE-SD was prepared viasolvent evaporation or solvent melting using PEG-6000 and PVP-K30 as carriers. Thermogravimetric analysis, X-ray diffraction spectroscopy, differential scanning calorimetry, Fourier transform infrared spectroscopy and scanning electron microscopy were used to identify the physical state of AE-SD. Optimal prescriptions were screened viathe dissolution degree determination method. Using Phoenix software, AE suspension and AE-SD were subjected to a pharmacokinetic comparison study analyzing the alteration of behavior in vivo after AE was prepared as a solid dispersion. Acute toxicity was assessed in mice, and the physiological toxicity was used as the determination criterion for toxicity.
Results: AE-SD showed that AE existed in the carrier in an amorphous state. Compared with polyethylene glycol, polyvinylpyrrolidone (PVP) inhibited AE crystallization, causing the drug to transform from a dense crystalline state to an amorphous form and increasing the degree of drug dispersion. Therefore, it was more suitable as a carrier material for AE-SD. The addition of poloxamer (POL) was more beneficial to the stability of solid dispersions and could reduce the amount of PVP. The dissolution test confirmed that the optimal ratio of AE to the composite vector AE-PVP-POL was 1:2:2, and its dissolution effect was also optimal. Based on the pharmacokinetic comparison, the drug absorption was faster and quickly reached the peak of blood drug concentration in AE-SD compared to AE, the Cmax of AE-SD was greater than that of AE, and t1/2 and mean residence time of AE-SD were less than AE. The results showed that the drug metabolism in AE-SD was better, and the residence time was shorter. The toxicology study showed that both AE and AE-SD had no toxicity.
Conclusion: This paper established that the solubility of the drug could be increased after preparing a solid dispersion, as demonstrated by in vitro dissolution experiments. In vivo pharmacokinetics studies confirmed that AE-SD could improve the bioavailability of AE in vivo, providing a new concept for the research and development of AE preparations.

Objective: To explore the relationship between autophagy and apoptosis regulated by puerarin during osteoblastogenesis.
Methods: In this study, the effects of puerarin on the autophagic activity and apoptosis level of osteoblast precursors (MC3T3-E1 cells) was observed. Subsequently, the roles of puerarin on B-cell lymphoma-2 (Bcl-2) phosphorylation at different sites in osteoblast precursors were observed. The effect of puerarin on the interaction between Bcl-2 and autophagy regulatory molecule or pro-apoptotic molecule was also investigated using Co-immunoprecipitation assays. In addition, the effect of puerarin on mitochondrial membrane potential of osteoblast precursors was also identified by mitochondrial membrane potential fluorescence probe assays.
Results: Our results showed that puerarin can promote the autophagic activity and apoptosis level of MC3T3-E1 cells. In addition, puerarin promoted Bcl-2 phosphorylation at Ser70 site, and the dissociation of Bcl-2-Beclin1 complex. Moreover, puerarin could enhance the binding of Bcl-2-Bcl-2-Associated X (Bax) complex in MC3T3-E1 cells. Furthermore, puerarin increased the mitochondrial membrane potential of MC3T3-E1 cells.
Conclusions: Therefore, puerarin promotes Beclin1 into autophagy flux through Bcl-2 phosphorylation at Ser70, thereby enhancing autophagy of osteoblast precursors, which mediates its anti-apoptotic role during osteoblastogenesis. Furthermore, the dissociation of Bcl-2-Beclin1 complex is conducive to the binding of Bcl-2-Bax complex, which resists the apoptosis of osteoblast precursors viathe increased mitochondrial membrane potential.

Stroke is the main cause of disability in the middle and old age. Hemiplegia, especially lower limb paralysis, often leads to the loss of self-care ability and a series of secondary injuries. The main method to improve hemiplegic limb movement is exercise therapy, but there are still many patients with disabilities after rehabilitation treatment. As one of the non-pharmacological therapies for stroke, acupuncture has been recognized to improve motor function in patients. Here, we propose a new method, anterior sciatic nerve acupuncture, which can stimulate both the femoral nerve and the sciatic nerve. We designed this study to determine the effect of this method on lower limb motor function. Sixty participants recruited with hemiplegia after cerebral infarction will be randomly assigned to the test group or control group in a 1:1 ratio. The control group will receive Xingnao Kaiqiao acupuncture, and the test group will receive anterior sciatic nerve acupuncture on this basis. All participants will get acupuncture treatment once a day, 6 times a week for 2 weeks. The primary outcome is Fugl-Meyer Assessment of Lower Extremity and the secondary outcomes are Modified Ashworth Scale and Modified Barthel Index. Data will be collected before treatment, 1 week after treatment, and 2 weeks after treatment, and then statistical analysis will be performed. This study can preliminarily verify the effect of anterior sciatic nerve acupuncture on improving lower limb motor function in patients with cerebral infarction, which may provide an alternative approach for clinical treatment of hemiplegia.

Hemiplegia, especially lower limb paralysis, often leads to the loss of self-care ability and a series of secondary injuries. The main method to improve hemiplegic limb movement is exercise therapy, but there are still many patients with disabilities after rehabilitation treatment. As one of the non-pharmacological therapies for stroke, acupuncture has been recognized to improve motor function in patients. Here, we propose a new method, anterior sciatic nerve acupuncture, which can stimulate both the femoral nerve and the sciatic nerve.
