ABSTRACT

AIM: To explore the effect of ethanol extract of costusroot (EEC) on gastric mucosa in gastric ulcer rats and related mechanism. METHODS: The rats were randomly divided into 5 groups: normal group, model group, sucralfate group, low-EEC group and high-EEC group, and anhydrous alcohol was administrated intragastrically to replicate gastric ulcer model in groups other than the normal. Changes in the area of gastric ulcer were observed and the inhibition rate of ulcer was calculated. The pathological changes of gastric tissue were measured by HE staining, and the protein expression levels of Bax and Bcl-2 were tested by immunohistochemistry and Western blot. RESULTS: EEC inhibited the formation of ulcer area in model rats and alleviated the histopathological damage to the stomach caused by ethanol. While enhancing the expression of Bcl-2 protein (P<0.01), it effectively inhibited the overexpression of Bax (P<0.01). CONCLUSION: EEC has a strong function of anti-gastric ulcers, and its mechanism of action might be related to the regulation of the protein expression level of Bax and Bcl-2 to inhibit the apoptosis of gastri mucosal cells.

ABSTRACT

Objective::To observe effect of addition and subtraction therapy of Huaihuasan combined with Taohuatang to ulcerative colitis with cold-heat complicated syndrome at active stage, and to study regulation effect to immune function and inflammatory response. Method::One hundred and twelve patients were randomly divided into control group and observation group by random number table. Patients with light and middle symptoms in control group got mesalazine slow release tablets, 1.0 g/time, 3 times/days, patients with severe symptoms or whose symptoms were not changed after getting for 4 weeks in control group got prednisone acetate tablets, 0.75 mg·kg-1·d-1 for 3 times. Based on the treatment in control group, patients in observation group added Huaihuasan combined with Taohuatang, 1 dose/day. The course of treatment was 4 weeks. At remission period, mesalazine slow release tablets were used for maintain long-term maintenance therapy, 0.5 g/times, 3 times/days. Scores of disease activities were graded by improvement mayo, and clinical remission and clinical efficacy were recorded, scores of cold-heat complicated syndrome, mucous membrane under enteroscopy and histology of mucosa belongs to Geboes were graded. And levels of tumor necrosis factor-α(TNF-α) in peripheral blood, interleukin-8 (IL-8), IL-10, T lymphocyte subsets (CD4+, CD8+), and adverse reactions, 6 months' follow-up and recurrence were also be recorded. Result::Therapeutic effect of traditional Chinese medicine syndromes were analyzed by rank sum test, which in observation group was better than that in control group (Z=1.915, P<0.05). Clinical effect in observation group was 98.04%(50/51) higher than 84.00%(42/50) in control group, clinical remission rate was 94.12%(48/51) higher than 78.00%(39/50) in control group, and mucosal healing rate was 96.08%(49/51) higher than 82.00%(41/50) in control group (P<0.05). Scores of mayo, cold-heat complicated syndrome, colonic mucosa and index scores of Geboes were all lower than those in control group (P<0.01). And levels of TNF-α, IL-8 and CD8+ were lower than those in control group (P<0.01), and levels of IL-10, CD4+ and CD4+ /CD8+ were higher than those in control group (P<0.01). Recurrence rate during 6 months in observation group was 10.42%(5/48) lower than 30.77%(12/39) in control group (χ2=5.669, P<0.05), as for adverse reactions, there was no significant difference between two groups. Conclusion::Huaihuasan combined with Taohuatang can induce UC to remission period, inhibit the activity of disease, alleviate clinical symptoms, regulate immune function and expression of inflammatory factors, alleviate inflammatory reaction, promote intestinal mucosal healing, and can maintain clinical remission and reduce recurrence.

ABSTRACT

Objective@#Interferon-induced transmembrane protein 3 (IFITM3) is an important member of the IFITM family. However, the molecular mechanisms underlying its antiviral action have not been completely elucidated. Recent studies on IFITM3, particularly those focused on innate antiviral defense mechanisms, have shown that IFITM3 affects the body's adaptive immune response. The aim of this study was to determine the contribution of IFITM3 proteins to immune control of influenza infection .@*Methods@#We performed proteomics, flow cytometry, and immunohistochemistry analysis and used bioinformatics tools to systematically compare and analyze the differences in natural killer (NK) cell numbers, their activation, and their immune function in the lungs of -/- and wild-type mice.@*Results@#-/- mice developed more severe inflammation and apoptotic responses compared to wild-type mice. Moreover, the NK cell activation was higher in the lungs of -/- mice during acute influenza infection.@*Conclusions@#Based on our results, we speculate that the NK cells are more readily activated in the absence of IFITM3, increasing mortality in -/- mice.

ABSTRACT

Objective@#To analyze the effects of the degree and location of intracranial vertebral artery(VA) lesions on the hemodynamic parameters of extracranial VA.@*Methods@#A total of 275 consecutive patients who were diagnosed as posterior circulation ischemic stroke or transient ischemic attack (TIA) with unilateral intracranial VA stenosis or occlusion in the Department of Neurology and Neurosurgery of Capital Medical University Xuanwu Hospital from January 2015 to December 2017 were enrolled. All patients were examined by head and neck vascular ultrasound, CT angiography (CTA) and/or digital subtraction angiography (DSA) within one week. According to the results of DSA or CTA, the patients were divided into mild stenosis group(53 patients), moderate stenosis group(62 patients), severe stenosis group(58 patients) and occlusion group(102 patients). The inner diameter (D), peak systolic velocity (PSV), end diastolic velocity (EDV), and resistance index (RI) of the extracranial segment (V2 segment) of the VA were recorded and analyzed.@*Results@#The PSV and EDV in the severe stenosis group and the occlusion group were significantly lower than those in the mild stenosis group and the moderate stenosis group (P=0.000), and the PSV and EDV in the occlusion group were significantly lower than those in the severe stenosis group[ (31±10) cm/s vs (46±12)cm/s, (5±4)cm/s vs (15±7)cm/s; all P=0.000], RI was significantly higher than the other three groups (0.85±0.12, 0.70±0.10, 0.66±0.07, 0.64±0.06, respectively; all P=0.000); RI in the severe stenosis group were not significantly different from those in the mild to moderate stenosis groups (P=0.044, 0.223). There were no significant differences in the inner diameter, PSV, EDV and RI between the subgroups in the severe stenosis group before or after the PICA (posterior inferior cerebellar artery)(P=0.130, 0.322, 0.865, 0.227). However, the EDV decreased and RI increased in the occlusive subgroup before the PICA when compared the subgroup after the PICA (all P=0.000).@*Conclusions@#The location and degree of intracranial VA lesions directly affect the changes of blood flow velocity and vascular resistance of extracranial VA, and the changes of low-speed and high-resistance hemodynamics of extracranial VA may indicate the existence of occlusive lesions in intracranial VA.

ABSTRACT

Objectives: To investigate the potential mechanism of cathepsins S inhibitor (CatS-I) affected ischemia-induced neovascularization in experimental mice. Methods: 8 week-old wild type (C57/BL6) mice were randomly divided into 2 groups: Control group, the mice received basic diet with intraperitoneal injection of 5% carboxymethylcellulose sodium and CatS-I group, the mice received basic diet with intraperitoneal injection of CatS-I (1mg/kg·d); all animals were treated for 17 days. n=20 in each group. Hind limb ischemia model was established at 3 days after injection in both groups. Blood flow was measured by laser Doppler blood flow analyzer, the ratio of ischemic area to non-ischemic area was calculated; protein expressions of peroxidase proliferation activated receptors-γ (PPAR-γ), p-Akt, p-eNOS and VEGF were examined by Western blot analysis at day 4 after the operation; frozen section of ischemic skeletal muscle was taken at 7 days after operation to measure capillary density by immunohistochemistry.Results: ① CatS-I inhibited blood flow recovery. Compared with Control group, CatS-I group had slower blood flow recovery in ischemic hind limb, P<0.05. ② CatS-I inhibited capillary formation. At 14 days after operation, capillary formation in non-ischemic skeletal muscles was similar between 2 groups, P>0.05; while in ischemic skeletal muscles, capillary density was lower in CatS-I group than Control group, P<0.01. ③ Compared with Control group, CatS-I group showed decreased protein expressions of PPAR-γ, p-Akt, p-Enos and VEGF, P<0.05. Conclusions: CatS-I regulated ischemia-induced neovascularization might be related to PPAR-γ activation and PI3K/Akt/eNOS signaling pathway in experimental mice.

ABSTRACT

AIM:To investigate the effect of microRNA(miR)-381-3p on neuronal injury in the hippocampus of depressive rats and the possible regulatory mechanism.METHODS:The rat model of depression was established by sub-cutaneous injection of corticosterone and the model rats received fluoxetine treatment.The body weight,open field test and biochemical indexes were measured for judging the therapeutic effect of fluoxetine.The expression of miR-381-3p,brain-derived neurotrophic factor(BNDF),Bcl-2 and Bax in the hippocampus was determined.The cultured neonatal rat hipp-ocampal neurons were pre-transfected with miR-381-3p inhibitor and then incubated with corticosterone.The cell viability, and the expression of miR-381-3p, BNDF, Bcl-2 and Bax were detected.The targeted regulatory role of miR-381-3p in BDNF was verified by luciferase reporter assay.RESULTS:Compared with depression group,fluoxetine increased the body weight,the number of cross-field activities and the content of norepinephrine,inhibited the expression of miR-381-3p and promoted the expression of BNDF in the hippocampus.miR-381-3p silencing reversed the effect of corticosterone,resulting in the increase in the survival rate of hippocampal neurons, upregulation of BDNF and Bcl-2, and downregulation of Bax expression.miR-381-3p targeted the regulation of BNDF expression.CONCLUSION: Silencing miR-381-3p protects rat hippocampal neurons from corticosterone injury,and its mechanism may be related to the upregulation of BNDF expression.

EPP epidemic model was employed to analyze the prevalence and to predict future epidemic situations.</p><p><b>RESULTS</b>A total of 830 000 and 1 020 000 people were monitored in 2003 and 2004 respectively, and 8 880 000 more people were monitored in the following 5 years. By the end of 2009, a total of 4103 HIV infection cases had been reported, among which 918 people were diagnosed with AIDS and 432 died. Since 2003, the cases infected through IDU had decreased from 66.84% (262/392) to 16.40% (142/868). However, the cases infected through sex contact had increased from 21.68% (85/392) to 77.40% (672/868). Among these cases, homosexual transmission and heterosexual transmission accounted for 39.10% (339/868) and 38.30% (333/868) respectively. It was estimated that there would be 14 290 HIV/AIDS cases in 2011 which is 18.10% (2191/12 099) higher than that in 2009. The estimated HIV infection rate would be 0.02%.</p><p><b>CONCLUSION</b>EPP prediction showed the AIDS epidemic situation in Jiangsu province had an ascendant trend and the AIDS epidemic situation had demonstrated rapid growth. Therefore, it is necessary to take effective preventive measures to control the spread of AIDS.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To explore the effects of survivin antisense RNA on apoptosis and chemosensitivity to docetaxel in gastric cancer line SGC7901 cells, and its relation to mdr-1.</p><p><b>METHODS</b>survivin antisense eukaryotic vector anti-pcDNA3-svv was transfected into SGC7901 cells by electorporation and positive clone was screened out. survivin protein and mdr-1 mRNA were determined by Western blot and RT-PCR. Apoptosis-inducing effect was examined by electron microscopy. Sensitivity to docetaxel was examined by MTT. Expression of mdr-1 and survivin mRNA were detected in the SGC7901 cells after drug-resisitance induction.</p><p><b>RESULTS</b>The expression of survivin protein of SGC7901 cells after transfection reduced significantly than that of non-transfected cells. MDR indexes of transfection group and non-transfection group were 0.196 +/- 0.013 and 3.126 +/- 0.019, respectively. The IC50 of transfection group to docetaxel was (16.7 +/- 1.98) microg/L and non-transfection group was (55.7 +/- 1. 89) microg/L, with a statistically significant difference. Expression of survivin mRNA in drug-resistant cells decreased along with the decreasing of mdr-1.</p><p><b>CONCLUSION</b>Antisense surivivin RNA can induce apoptosis in gastric cancer cells and increase sensitivity to docetaxel. The reversing mechanism of drug resistance is related with decreasing of mdr-1.</p>

ABSTRACT

Hepatic fibrosis is the most important pathologic course for chronic hepatic injury developing into hepatic cirrhosis. It is meaningful for treating liver disease by inhibiting the development of hepatic fibrosis. Recently, herbs of promoting blood circulation for removing blood stasis has their unique characteristics and exhibits great therapeutic effect on hepatic fibrosis. The review explains the function and mechanism of the promoting blood circulation for removing blood stasis herbs in treating hepatic fibrosis from the aspects of the monomer, effective constituent and compound recipe. It provides basis for application of promoting blood circulation for removing blood stasis herbs in study and treating hepatic fibrosis.
