Hovenia dulcis: a Chinese medicine that plays an essential role in alcohol-associated liver disease.

Globally, alcohol-associated liver disease (ALD) has become an increased burden for society. Disulfirams, Benzodiazepines (BZDs), and corticosteroids are commonly used to treat ALD. However, the occurrence of side effects such as hepatotoxicity and dependence, impedes the achievement of desirable and optimal therapeutic efficacy. Therefore, there is an urgent need for more effective and safer treatments. Hovenia dulcis is an herbal medicine promoting alcohol removal clearance, lipid-lowering, anti-inflammatory, and hepatoprotective properties. Hovenia dulcis has a variety of chemical components such as dihydromyricetin, quercetin and beta-sitosterol, which can affect ALD through multiple pathways, including ethanol metabolism, immune response, hepatic fibrosis, oxidative stress, autophagy, lipid metabolism, and intestinal barrier, suggesting its promising role in the treatment of ALD. Thus, this work aims to comprehensively review the chemical composition of Hovenia dulcis and the molecular mechanisms involved in the process of ALD treatment.

Research progress on the treatment of diabetic nephropathy with leech and its active ingredients.

Diabetic nephropathy (DN) is a major microvascular complication of diabetes and a common cause of chronic kidney disease. There is currently a lack of effective treatments for DN, and the prognosis for patients remains poor. Hirudin, one of the primary active components derived from leeches, demonstrates anti-coagulant, anti-fibrotic, anti-thrombotic, and anti-inflammatory properties, exhibiting significant protective effects on the kidneys. In recent years, there has been a surge of interest in studying the potential benefits of hirudin, especially in its role in the management of DN. This article delves into the mechanisms by which hirudin contributes to the treatment of DN and its clinical efficacy.

Dioscorea nipponica Makino: A comprehensive review of its chemical composition and pharmacology on chronic kidney disease.

Chronic kidney disease (CKD) is a widespread ailment that significantly impacts global health. It is characterized by high prevalence, poor prognosis, and substantial healthcare costs, making it a major public health concern. The current clinical treatments for CKD are not entirely satisfactory, leading to a high demand for alternative therapeutic options. Chinese herbal medicine, with its long history, diverse varieties, and proven efficacy, offers a promising avenue for exploration. One such Chinese herbal medicine, Dioscorea nipponica Makino (DNM), is frequently used to treat kidney diseases. In this review, we have compiled studies examining the mechanisms of action of DNM in the context of CKD, focusing on five primary areas: improvement of oxidative stress, inhibition of renal fibrosis, regulation of metabolism, reduction of inflammatory response, and regulation of autophagy.

2,3-Butanediol from the leachates of pine needles induces the resistance of Panax notoginseng to the leaf pathogen Alternaria panax.

Compared with the use of monocultures in the field, cultivation of medicinal herbs in forests is an effective strategy to alleviate disease. Chemical interactions between herbs and trees play an important role in disease suppression in forests. We evaluated the ability of leachates from needles of Pinus armandii to induce resistance in Panax notoginseng leaves, identified the components via gas chromatography-mass spectrometry (GC-MS), and then deciphered the mechanism of 2,3-Butanediol as the main component in the leachates responsible for resistance induction via RNA sequencing (RNA-seq). Prespraying leachates and 2,3-Butanediol onto leaves could induce the resistance of P. notoginseng to Alternaria panax. The RNA-seq results showed that prespraying 2,3-Butanediol onto leaves with or without A. panax infection upregulated the expression of large number of genes, many of which are involved in transcription factor activity and the mitogen-activated protein kinase (MAPK) signaling pathway. Specifically, 2,3-Butanediol spraying resulted in jasmonic acid (JA) -mediated induced systemic resistance (ISR) by activating MYC2 and ERF1. Moreover, 2,3-Butanediol induced systemic acquired resistance (SAR) by upregulating pattern-triggered immunity (PTI)- and effector-triggered immunity (ETI)-related genes and activated camalexin biosynthesis through activation of WRKY33. Overall, 2,3-Butanediol from the leachates of pine needles could activate the resistance of P. notoginseng to leaf disease infection through ISR, SAR and camalexin biosynthesis. Thus, 2,3-Butanediol is worth developing as a chemical inducer for agricultural production.

A chemoenzymatic strategy for site-selective functionalization of native peptides and proteins.

The emergence of new therapeutic modalities requires complementary tools for their efficient syntheses. Availability of methodologies for site-selective modification of biomolecules remains a long-standing challenge, given the inherent complexity and the presence of repeating residues that bear functional groups with similar reactivity profiles. We describe a bioconjugation strategy for modification of native peptides relying on high site selectivity conveyed by enzymes. We engineered penicillin G acylases to distinguish among free amino moieties of insulin (two at amino termini and an internal lysine) and manipulate cleavable phenylacetamide groups in a programmable manner to form protected insulin derivatives. This enables selective and specific chemical ligation to synthesize homogeneous bioconjugates, improving yield and purity compared to the existing methods, and generally opens avenues in the functionalization of native proteins to access biological probes or drugs.

Association between cine CMR-based radiomics signature and microvascular obstruction in patients with ST-segment elevation myocardial infarction.

Background: In the process of percutaneous coronary intervention (PCI), patients with ST-segment elevation myocardial infarction (STEMI) may receive large doses of the iodine contrast agent. Some adverse events may be aroused if the patients receive the gadolinium agents. We investigate the association between cine cardiac magnetic resonance (CMR)-based radiomics signature and microvascular obstruction (MVO) in patients with STEMI. Methods: A total of 116 STEMI patients who received continuous CMR within 6 days after PCI were retrospectively included in this study. According to the late gadolinium enhancement (LGE) of CMR, the myocardial infarction (MI) was divided into with and without MVO. Radiomic features were extracted from cine CMR images and the least absolute shrinkage and selectionator operator (LASSO) algorithm was used for features selection and radiomic signatures construction. Binary logistic regression was used to assess association between radiomic signatures and MVO with adjusted for baseline clinical characteristics. Results: Of 116 patients with STEMI, MI with MVO was found in 50 patients and MI without MVO was found in 66 patients. LASSO regression selected five radiomics features for radiomics signature construction. Logistic regression revealed that radiomics score, high sensitivity C-reactive protein (hs-CRP) and creatine phosphokinases (CPK) were independent risk factors for MVO with odds ratio (OR) of 4.41 (95% CI: 2.26-9.93), 1.018 (95% CI: 1.006-1.034) and 1.0007 (95% CI: 1.0004-1.0012), respectively. Area under curve (AUC) of receiver operating characteristic (ROC) of radiomics score to predict MVO was 0.75 (95% CI: 0.68-0.85). Conclusions: Cine CMR-based radiomics signature was an independent predictive factor of MVO in patients with STEMI, which showed the potential of this contrast free radiomics signature to be an imaging biomarker for MVO.

Appropriate Soil Heat Treatment Promotes Growth and Disease Suppression of Panax notoginseng by Interfering with the Bacterial Community.

In our greenhouse experiment, soil heat treatment groups (50, 80, and 121°C) significantly promoted growth and disease suppression of Panax notoginseng in consecutively cultivated soil (CCS) samples (p < 0.01), and 80°C worked better than 50°C and 121°C (p < 0.01). Furthermore, we found that heat treatment at 80°C changes the microbial diversity in CCS, and the inhibition ratios of culturable microorganisms, such as fungi and actinomycetes, were nearly 100%. However, the heat-tolerant bacterial community was preserved. The 16S rRNA gene and internal transcribed spacer (ITS) sequencing analyses indicated that the soil heat treatment had a greater effect on the Chao1 index and Shannon's diversity index of bacteria than fungi, and the relative abundances of Firmicutes and Proteobacteria were significantly higher than without heating (80 and 121°C, p < 0.05). Soil probiotic bacteria, such as Bacillus (67%), Sporosarcina (9%), Paenibacillus (6%), Paenisporosarcina (6%), and Cohnella (4%), remained in the soil after the 80°C and 121°C heat treatments. Although steam increased the relative abundances of most of the heat-tolerant microbes before sowing, richness and diversity gradually recovered to the level of CCS, regardless of fungi or bacteria, after replanting. Thus, we added heat-tolerant microbes (such as Bacillus) after steaming, which reduced the relative abundance of pathogens, recruited antagonistic bacteria, and provided a long-term protective effect compared to the steaming and Bacillus alone (p < 0.05). Taken together, the current study provides novel insight into sustainable agriculture in a consecutively cultivated system.

[Effect of acupuncture on pain-emotion related brain regions in patients with cervical spondylosis of cervical type: a fMRI study].

OBJECTIVE: To observe the changes of functional connectivity of brain pain-emotion regulation region in patients with cervical spondylosis of cervical type by functional magnetic resonance imaging (fMRI). METHODS: Thirty-two subjects were selected. Of them, 16 patients with cervical spondylosis of cervical type were divided into an observation group and 16 healthy subjects into a control group. The patients in the observation group were treated with acupuncture at Tianzhu (BL 10), Jingbailao (EX-HN 15), Jianzhongshu (SI 15) and ashi points for 30 min. The rest-state fMRI data was collected before and after acupuncture in the observation group. The subjects in the control group received no treatment, and the rest-state fMRI data was collected once. The visual analogue scale (VAS) score before and after treatment and the pain catastrophizing scale (PCS) score before treatment in the observation group were recorded. The resting-state brain functional imaging characteristics between the observation group and control group before treatment, between the observation group before and after treatment, were compared. Based on the brain functional connectivity of region of interest (ROI) the changes of functional connectivity in insula and ventral tegmental area (VTA) in emotional regulation brain region were observed, and the correlation between functional connectivity changes and VAS、PCS scores in patients of the observation group was analyzed. RESULTS: In the observation group, the VAS score was (1.94±1.12) after the treatment, which was lower than (5.62±1.20) before treatment (P<0.05). The PCS score before treatment was (19.18±8.42) in the observation group. Compared with the control group, the areas with increased functional connectivity with insula in the observation group before acupuncture included bilateral dorsolateral prefrontal lobe and right middle cingulate gyrus, and the areas with increased functional connectivity with VTA included right central posterior gyrus and right insula. In the observation group, the connectivity coefficient of left insula and left dorsolateral prefrontal lobe (r=0.438, P<0.05), the connectivity coefficient of right insula and right dorsolateral prefrontal lobe (r=0.483, P<0.05) were positively associated with the VAS score. In the observation group, the connectivity coefficient between the right insula and the right middle cingulate gyrus (r=-0.560, P<0.05), the connectivity coefficient between the right VTA and the right insula (r=-0.525, P<0.05) were negatively associated with the PCS score. After acupuncture, the areas with decreased functional connectivity with insula included bilateral posterior central gyrus, right anterior central gyrus, middle cingulate gyrus and left corpus callosum, while the bilateral suboccipital gyrus and left cerebellum showed increased functional connectivity with right insula. The areas with decreased functional connectivity with VTA included bilateral dorsomedial prefrontal cortex, left anterior cingulate gyrus, right middle temporal gyrus and left anterior cingulate gyrus. After acupuncture in the observation group, the functional connectivity of left VTA left dorsomedial prefrontal cortex and left anterior cingulate cortex (r=-0.548, P<0.05), the functional connectivity of right VTA-bilateral dorsomedial prefrontal cortex and left anterior cingulate cortex (r=-0.547, P<0.05) were negatively associated with the PCS score. CONCLUSION: Pain involves the formation and expression of "pain-emotion-cognition". Acupuncture can systematically regulate the brain functional connections between cognitive regions such as dorsal prefrontal lobe and anterior cingulate gyrus and emotional regions such as insula and VTA in patients with cervical spondylosis of cervical type, suggesting that acupuncture has a multi-dimensional and comprehensive regulation effect on pain.

Network Pharmacology Reveals Polyphyllin II as One Hit of Nano Chinese Medicine Monomers against Nasopharyngeal Carcinoma.

Nasopharyngeal carcinoma (NPC) is a malignant tumor in southern China, and nano Traditional Chinese Medicine (TCM) represents great potential to cancer therapy. To predict the potential targets and mechanism of polyphyllin II against NPC and explore its possibility for the future nano-pharmaceutics of Chinese medicine monomers, network pharmacology was included in the present study. Totally, ninety-four common potential targets for NPC and polyphyllin II were discovered. Gene Ontology (GO) function enrichment analysis showed that biological processes and functions mainly concentrated on apoptotic process, protein phosphorylation, cytosol, protein binding, and ATP binding. In addition, the anti-NPC effects of polyphyllin II mainly involved in the pathways related to cancer, especially in the PI3K-Akt signaling indicated by the Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis. The "drug-target-disease" network diagram indicated that the key genes were SRC, MAPK1, MAPK14, and AKT1. Taken together, this study revealed the potential drug targets and underlying mechanisms of polyphyllin II against NPC through modern network pharmacology, which provided a certain theoretical basis for the future nano TCM research.

Application of "process management and evaluation" in resident standardization training plan in acupuncture-moxibustion department of hospital for postgraduates of non-acupuncture- moxibustion speciality / 中国针灸

The teaching effect of "process management and evaluation" was assessed in resident standardization training plan in acupuncture-moxibustion department of hospital for postgraduates of non-acupuncture-moxibustion speciality. A total of 120 postgraduates of non-acupuncture-moxibustion speciality participating in resident standardization training were randomized into an observation group (60 cases) and a control group (60 cases, 1 case dropped off). In the control group, the conventional training mode was used. In the observation group, the "process management and evaluation" was adopted, in which, the syllabus was refined, various teaching modes were cooperated and the summary was conducted once a week. The training results were evaluated at the end of 1-month shift test and questionnaire was issued in all of the postgraduates of the two groups. In the observation group, the score for theory and the score of each of the items for technical ability, named differentiation and treatment, technical manipulation and physician-patient communication, as well as the total score were all higher than the control group successively (

Marinoid J, a phenylglycoside from Avicennia marina fruit, ameliorates cognitive impairment in rat vascular dementia: a quantitative iTRAQ proteomic study.

CONTEXT: Fruit of Avicennia marina (Forsk.) Vierh. (Acanthaceae) is used as a Chinese herb. Studies have found that it contains marinoid J, a novel phenylethanoid glycoside (PG) compound, but its neuroprotective functions are largely unknown. OBJECTIVE: This study evaluated the effects of marinoid J on vascular dementia (VD) and determined its potential mechanisms of action. MATERIALS AND METHODS: The VD model was established by the ligation of the bilateral common carotid artery in Sprague-Dawley rats, who received daily intragastrically administration of saline, marinoid J (125 or 500 mg/kg body weight/d), or oxiracetam (250 mg/kg body weight/d) for 14 days (20 rats in each group). The Morris water maze (MWM) was used to evaluate cognitive performance. The hippocampus was subjected to histological and proteomic analyses. RESULTS: Marinoid J shortened the escape latency of VD rats (31.07 ± 3.74 s, p < 0.05). It also decreased malondialdehyde (MDA) (27.53%) and nitric oxide (NO) (20.41%) while increasing superoxide dismutase (SOD) (11.26%) and glutathione peroxidase (GSH-Px) (20.38%) content in hippocampus tissues. Proteomic analysis revealed 45 differentially expressed proteins (DEPs) in marinoid J-treated VD rats, which included angiotensin-converting enzyme (ACE), keratin 18 (KRT18), cluster of differentiation 34 (CD34), and synaptotagmin II (SYT2). CONCLUSIONS: Marinoid J played a role in protecting hippocampal neurons by regulating a set of proteins that influence oxidative stress and apoptosis, this effect may thereby alleviate the symptoms of VD rats. Thus, pharmacological manipulation of marinoid J may offer a novel opportunity for VD treatment.

Effects of plant oils with different fatty acid composition on cardiovascular risk factors in moderately hypercholesteremic Chinese adults: a randomized, double-blinded, parallel-designed trial.

OBJECTIVES: Plant oil for cooking typically provides 40% to 50% of dietary fat, 65% of linoleic acid, 44% of α-linolenic acid and 41% of oleic acid in the Chinese diet. However, the comparative effects of fatty acids derived from plant oil on cardiovascular risk factors in Chinese are still inconclusive. Hence, the aim of this study is to investigate whether cardiovascular risk factors are altered depending on various types of plant oils such as peanut oil rich in oleic acid, corn oil rich in linoleic acid, and blend oil fortified by α-linolenic acid. DESIGN: A randomized, double-blinded, parallel-designed trial. SETTING: The First and the Second Affiliated Hospital of Sun Yat-sen University, Guangzhou, China. PARTICIPANTS: A total of 251 volunteers with fasting blood total cholesterol between 5.13 and 8.00 mmol L-1 were enrolled. INTERVENTION: Volunteers received peanut oil, corn oil or blend oil to use for cooking for one year. MAIN OUTCOME MEASURES: The erythrocyte membrane fatty acid composition, fasting plasma lipids, glucose and insulin concentrations and high sensitivity C-reactive protein (hsCRP) levels were measured before, during and after the intervention. The level of α-linolenic acid in erythrocyte membranes was significantly increased in the blend oil group after the intervention (P < 0.001). The level of other fatty acids did not show any statistically significant differences between the three groups. No significant differences were observed in the concentrations of fasting plasma lipids, hsCRP, glucose, and insulin among the three groups using different types of plant oils. CONCLUSIONS: The results suggest that although ingesting cooking oil with different fatty acid composition for one year could change erythrocyte membrane fatty acid compositions, it did not significantly modify cardiovascular risk factors in moderately hypercholesteremic people.

Application of Meridian Electrical Conductance in the Setting of Acute Ischemic Stroke: A Cross-Sectional Study.

Acupuncture is widely used for improving poststroke care. Knowing the condition of meridian can help traditional Chinese medicine (TCM) doctors make a tailored choice of acupoints for every patient. The establishment of an objective meridian energy measurement for acute ischemic stroke that can be used for future acupuncture treatment and research is an important area in stroke-assisted therapy. In this study, a total of 102 subjects diagnosed with acute ischemic stroke within 7 days of onset were recruited, and the meridian energy analysis device (MEAD) was used to record the meridian electrical conductance (MEC) values of twelve meridians on unaffected and affected limbs. We found that the MEC value of the twelve meridians on the affected limbs was significantly higher than that on the unaffected limbs (P=0.001). Compared with the unaffected limbs, there was a higher value of MEC on the affected limbs of the lung meridian, heart meridian, pericardium meridian, and small intestine meridian, with significant differences (P < 0.05, P < 0.001, P < 0.001, and P < 0.05, respectively). Further analysis revealed that the MEC values of both Yin and Yang meridians of the affected limbs were significantly higher than those of the unaffected limbs (P=0.001 and P < 0.05, respectively). Meanwhile, the mean of the index of sympathovagal balance in patients with acute ischemic stroke (5.49 ± 4.21) was higher than the normal range (1-1.5), indicating autonomic imbalance. The results of this study are consistent with TCM theory as well as clinical observation and pathological mechanisms, suggesting that the measurement of MEC values may be used as a supplementary diagnostic method for acupuncture in patients with acute ischemic stroke.

Optimization of Ultrasound-Assisted Extraction of Monoterpene Glycoside from Oil Peony Seed Cake.

Ultrasound-assisted extraction (UAE) of total monoterpene glycosides extract (TMGE) from oil peony seed cakes was investigated. The extraction yield was optimized using response surface methodology (RSM). The chemical constituents of the monoterpene glycosides extract were isolated by repeated column chromatography, and the contents of the main isolated monoterpene glycosides in the oil peony seed cakes were determined by HPLC. The optimum conditions were as follows: a liquid-to-solid ratio of 27 mL/g, ultrasonic extraction time of 16 min, ultrasonic extraction temperature of 26 °C, and ethanol concentration of 67%. Under these conditions, the extraction yield of TMGE was 10.24%. Twenty monoterpene glycosides were isolated from the oil peony seed cakes, and compounds 11-12, 16 and 20 showed strong inhibitory activities on NO production. TMGE from oil peony seed cakes can also to be used as promising immunosuppressive drug due to its high content of monoterpene glycosides and immune-inhibitory activity. PRACTICAL AAPPLICATION: The peony seed oil was authorized as a new food by the Ministry of Health of the People's Republic of China. Peony seed cake is one of the most important by-products in the preparation of peony seed oil, and accounts for approximately 40% of the total mass of the peony seed. Total monoterpene glycosides are the main active ingredient of oil peony seed cake. This research has optimized the extraction conditions of total monoterpene glycoside from seeds cake of Paeonia ostii, which will provide useful reference information for further studies, and offer related industries with helpful guidance in practice.

Relationship between Tissue Distributions of Modified Wuzi Yanzong Prescription () in Rats and Meridian Tropism Theory.

OBJECTIVE: To investigate the relationship between tissue distributions of modified Wuzi Yanzong prescription (, MWP) in rats and meridian tropism theory. METHODS: A high-performance liquid chromatography with Fourier transform-mass spectrometry (HPLC-FT) method was used to identify the metabolites of MWP in different tissues of rats after continued oral administration of MWP for 7 days. The relationship between MWP and meridian tropism theory was studied according to the tissue distributions of the metabolites of MWP in rats and the relevant literature. RESULTS: Nineteen metabolites, mainly flavanoid compounds, were detected in the different rat tissues and classified to each herb in MWP. Further, it was able to establish that the tissue distributions of the metabolites of MWP were consistent with the descriptions of meridian tropism of MWP available in literature, this result might be useful in clarifying the mechanism of MWP on meridian tropism. In the long run, these data might provide scientific evidence of the meridian tropism theory to further promote the reasonable, effective utilization, and modernization of Chinese medicine. CONCLUSION: The tissue distributions of MWP in vivo were consistent with the descriptions of meridian tropism of MWP.

Interactive effects of environmental factors on phytoplankton communities and benthic nutrient interactions in a shallow lake and adjoining rivers in China.

Shallow lakes are vulnerable to eutrophication because of abundant phytoplankton and significant nutrient input from sediments. Previous studies have researched the effect of environmental factors on phytoplankton and phosphorus release from sediment. However, few studies have simultaneously evaluated the interactive effects of environmental factors on phytoplankton communities and the interactions among different sediment nutrients. This paper reports on a 2016 investigation that examined the phytoplankton community and physical and chemical factors in both the water column and sediments in a Chinese shallow lake and its adjoining rivers. Our results indicated that rivers with water gates and lake areas had greater Chlorophyll a concentrations (Chl a) than natural rivers with similar total phosphorus (TP) concentrations; this indicates the importance of residence time on phytoplankton biomass. Although temperature impacted Chl a less than nutrients, its effects were highly species-specific, modulating relationships between nutrients and the abundance of different phytoplankton taxa. The effects of nutrients changed based on phytoplankton biomass and community composition, suggesting that different phytoplankton taxa have different nutrient demands. We predict that increasing residence time, temperature, and nutrients will increase phytoplankton biomass and increase the future dominance of Chlorophyta and Cyanophyta. In the interstitial water, there were no significant seasonal differences in TP, total nitrogen, and soluble reactive silica concentrations. However, ammonia concentrations were higher in the spring and lower in other seasons; nitrate and sulfate were abundant when the ammonia concentration was low. The total iron level in sediments was significantly negatively related with TP at low ammonia and silica concentrations and at high nitrate and sulfate concentrations in the interstitial water. These results indicated that nutrients are closely coupled in the sediments, highlighting the importance of oxidation-reduction potentials on internal nutrient balance.

Objective To investigate the effect and the mechanism of Qingbaikuijietang enema on colonic mucosa heal-ing and serum inflammatory factors in patients with ulcerative colitis(UC)and large intestine damp-heat syndrome. Methods A total of 120 patients with mild and moderate UC were selected from January 2014 to December 2015 in the Second Affilia-ted Hospital of Shaanxi University of Traditional Chinese Medicine. The patients were randomly divided into control group and observation group,with 60 cases in each group. The patients in the two groups were treated with mesalazine sustained release granules 1 g by oral,4 times a day for 4 weeks. Based on this,the patients in the observation group were given retention enema with Qingbaikuijietang,once a day for 4 weeks. The score of colonic mucosa healing under endoscopy were evaluated before and at 4 weeks after treatment. The levels of serum tumor necrosis factor-α(TNF-α)and interleukin-6(IL-6)were determined by enzyme linked immunosorbent assay,and the level of C-reactive protein(CRP)was determined by scattering turbidimetry be-fore and after 4 weeks of treatment. The endoscopic colonic lesions of all patients were scored by Rachmilewitz scoring standard before and after treatment. The clinical effect was evaluated by the standard set by the Cooperative Group of Inflammatory Bow-el Disease in Digestive Diseases Branch of Chinese Medical Association after 2 and 4 weeks of treatment. Results There was no significant difference in the score of colon mucosa healing between the two groups before treatment(P > 0. 05). The score of colonic lesions in the observation group was significantly lower than that in the control group after 4 weeks of treatment(P <0. 05). A total of 53 cases(88. 33％)in the observation group and 43 cases(71. 67％)in the control group were endoscopi-cally remission,the remission rate in the observation group was significantly higher than that in the control group(χ2 = 5. 208, P < 0. 05). There was no significant difference in serum IL-6,TNF-α and CRP levels between the two groups before treatment (P > 0. 05). The levels of serum IL-6,TNF-α and CRP after 4 weeks of treatment were significantly lower than those before treatment in the two groups(P < 0. 05). The levels of serum IL-6,TNF-α and CRP in the observation group were significantly lower than those in the control group after 4 weeks of treatment(P < 0. 05). The total effective rate in the control group and the observation group was 40. 00％ and 88. 34％ respectively after 2 weeks of treatment,and it was 86. 67％ and 96. 67％ respec-tively after 4 weeks of treatment,the total effective rate in the observation group was significantly higher than that in the control group after 2 and 4 weeks of treatment(χ2 = 30. 480,3. 927;P < 0. 05). Conclusion Qingbaikuijietang enema combined with mesalazine sustained release granules can reduce the levels of serum inflammatory inflammatory factors,inhibit the inflammato-ry reaction,promote the healing of colonic mucosa and alleviate the clinical symptoms in patients with UC.

[Effect of Aralia echinocaulis containing serum on Wnt/ß-catenin signaling pathway of primary osteoblast].

This paper was aimed to investigate the effect of Aralia echinocaulis containing serum on expression of ß-catenin, Wnt-1, Frizzed-2, TCF and Axin in Wnt/ß-catenin signaling pathway of primary osteoblasts. SD healthy female rats (n=80) were used to make A. echinocaulis containing serum by gastric perfusion for seven days with distilled water, A. echinocaulis decoction high dosage, middle dosage, and low dosage. In vitro, primary osteoblasts were cultured and identified. The third generation primary osteoblasts were taken and cultured for 48 h, then cells were treated with the different drug serums for 10 days and calcified nodules were counted by alizarin red staining. The cells were collected after treatment for 48 h and the expression levels of ß-catenin, Wnt-1, Frizzled-2, TCF and Axin were detected by Real-time PCR and Western blot. The results suggested that the in vitro cells were primary osteoblasts; and after treatment, various doses groups could promote the mineralization ability of primary osteoblasts, up-regulate the mRNA and protein expression levels of ß-catenin, Wnt-1, Frizzled-2, and TCF, and down-regulate the mRNA and protein expression levels of Axin. These findings indicated that A. echinocaulis containing serum can enhance the differentiation and proliferation of osteoblasts by regulating the expression levels of ß-catenin, Wnt-1, Frizzled-2, TCF and Axin in Wnt/ß-catenin signaling pathway of primary osteoblasts.
