ABSTRACT

Objective:To study the effect of Huanglian-Jiedu Decoction on the white matter lesion of rats with focal cerebral ischemia and to explore the regulative role of the active fraction of Huanglian-Jiedu Decoction on NogoA/NgR. Methods:Male SD rats were randomly divided into sham operation group, model group, total alkaloid group, total flavonoid group, and total iridoid group. Except for the sham operation group, the rats in the other groups were used to establish the middle cerebral artery occlusion rat model by the suture method. 2 hours after modeling, rats in the total alkaloid group were given intragastric administration with 44 mg/kg total alkaloids; rats in the total flavonoid group were given intragastric administration 50 mg/kg total flavonoids; rats in the total iridoid group were given intragastric administration 80 mg/kg total iridoids, the sham operation group and the model group were intragastrically given equal volume of normal saline, once a day, for 7 consecutive days. The pathological changes of rat white matter were observed by HE staining, the pathological changes of rat myelin sheath were observed by Luxol fast blue (LFB) staining, and the expression of Amyloid precursor protein (APP), NogoA, and NgR in the internal and external capsule areas of the brain was detected by immunohistochemical staining. Real-time fluorescence quantitative PCR was used to detect the expression of NogoA and NgR in the tissues surrounding the ischemic infarct.Results:Compared with the model group, the total alkaloid group, total flavonoid group, and total iridoid group had lower pathological damage scores in the internal and external capsule areas of rats ( P<0.05 or P<0.01), increased integral optical density value of LFB staining ( P<0.01), decreased expression of APP and NogoA; the expression of NgR in the internal and external capsules of rats in the total alkaloid group and the total iridoid group decreased ( P<0.05 or P<0.01), and the expression of NgR in the inner capsule of rats in the total flavonoid group decreased ( P<0.01); the expression of NogoA (1.20 ± 0.17, 1.55 ± 0.30, 1.19 ± 0.38 vs. 2.22 ± 0.58) and NgR (1.98 ± 0.55, 1.48 ± 0.31, 1.58 ± 0.27 vs. 3.36 ± 0.41) genes in the tissues around the infarct focus of rats in the total alkaloid group, total flavonoid group and total iridoid group decreased ( P<0.01). Conclusion:The present study investigates the therapeutic effects of Huanglian-Jiedu Decoction, promoting white matter repair by decreasing the overexpression of NogoA and NgR in an experimental animal model of stroke.

ABSTRACT

Objective To explore the effects of probiotics on intestinal function, nutritional status and inflammatory response in critically ill patients with enteral nutrition (EN) support. Methods A total of 90 critically ill patients admitted to Intensive Care Unit (ICU) of the First Affiliated Hospital of Anhui Medical University from July 2016 to November 2018 were enrolled, and they were divided into a probiotics combined with EN group (27 cases) and an simple EN group (63 cases) according to random number table method. The patients in the simple EN group were treated with conventional nutrient preparations such as fresubin or fresubin energy fibre; the patients in probiotics combined with EN group were supplemented with probiotics on the basis of conventional EN support for consecutive 7 days in both groups. The changes of gastrointestinal function, nutritional index and inflammatory response index after treatment were observed in both groups. Results After treatment, the subjective global assessment (SGA) method was used to identify the gradation of the patients, it was shown that the proportion of SGA-B grade patients in simple EN group had an upward trend; while the proportion of SGA-B grade patients in probiotics combined with EN group had no significant change; and there was no significant difference in the proportion of SGA-B patients between simple EN group and probiotics combined with EN group after treatment [20.6% (13/63) vs. 7.4% (2/27),P > 0.05]. Compared with those before treatment, the levels of hemoglobin (Hb), white blood cell count (WBC), C-reactive protein (CRP), tumor necrosis factor-α (TNF-α) and interleukins (IL-6, IL-12) in both groups were significantly decreased, while the levels of albumin (Alb), pre-albumin (PA), total lymphocyte count (TLC) in both groups were increased after treatment, and the changes of Hb, TNF-α, IL-6 in probiotics combined with EN group were more significant than those in the simple EN group [Hb (g/L): 95.0 (78.0, 107.0) vs. 93.0 (80.0, 107.0), TNF-α (pg/L): 21.2±4.0 vs. 28.0±5.7, IL-6 (pg/L): 161.3±37.6 vs. 186.2±51.8];the differences in levels of Hb, CRP, TNF-α before and after treatment between the probiotics combined with EN group and simple EN group were statistically significant [Hb (g/L): 1.0 (-4.0, 12.0) vs. 11.0 (1.0, 20.0), CRP (mg/L): 44.3 (13.7, 57.7) vs. 7.5 (-20.1, 62.4), TNF-α (pg/L): 13.3±6.3 vs. 7.9±5.5, all P < 0.05]. There were no statistical significant differences in the other indicators between the two groups (all P > 0.05). Conclusion Probiotics can improve the gastrointestinal function and inflammatory status of critically ill patients with EN support, regretfully, in a short term, the improvement of nutritional status of such patients is not obvious, but probiotics has certain significance in preventing the risk of aggravation of malnutrition and reduction of Hb level.

ABSTRACT

Objective To establish Metrigel-VEGF-SW982 complexes and use the complexes to produce animal models of synovial sarcoma so as to provide new ideas for establishing other models of soft tissue tumors. Methods After the SW982 cells were cultured and collected,they were resuspended with Metrigel,and VEGF was added.The suspension was seeded into transwell to establish the scaffold complexes of Metrigel-VEGF-SW982.The complexes were cultured overnight.Cryosections were made and HE staining was carried out to observe the cell scaffold complexes.We randomly divided 10 female SCID mice(4 week old)into scaffold group and control group. The mice in the scaffold group were transplanted with cell-scaffold complexes,and the control group with cell suspension.After 8 weeks,the success rate of modeling was compared between two groups.The mice were sacrificed and the tumors were obtained.HE staining was carried out to observe the histopathological features of tumors in both scaffold group and control group.Results The SW982 cells were cultured with Matrigel in a 3D way,which could simulate the growth condition of cells in vivo.Establishing synovial sarcoma animal model with cell scaffold complex could increase the success rate.The tumors in scaffold group had a larger volume,higher density of tumor cells and greater vascularization(P<0.05).Conclusion Establishing synovial sarcoma animal model with Metrigel-VEGF-SW982 complex can greatly improve the success rate of modeling,which can provide basis for the study of synovial sarcoma.

ABSTRACT

AIM: To investigate the effect of tumor necrosis factor receptor associated factor 6 (TRAF6) on proliferation, apoptosis and invasion of retinoblastoma Y79 cells. METHODS: The Y79 cells were divided into three groups:blank control group, negative control group and TRAF6 siRNA group. After TRAF6 siRNA transfection, the levels of TRAF6 mRNA and protein in Y79 cells were examined by RT-PCR and Western blotting. MTT assay was used to detect cell proliferation. Flow cytometry was employed to detect changes in cell cycle and apoptosis. Cell invasiveness was detected by the Transwell method. RESULTS: Expression of TRAF6 mRNA and protein in the TRAF6 siRNA group significantly decreased compared with the negative and blank control groups. Following the silencing of TRAF6,cell proliferation was inhibited and the apoptosis rate increased; the cell cycle was arrested at G0/G1 phase; the number of cells in S phase was reduced, while the invasion ability of cancer cells decreased. CONCLUSION: Silencing TRAF6 may inhibit the proliferation of Y79 cells, promote cell apoptosis, arrest the cell cycle at G0/G1 phase and decrease the invasive ability. Thus,TRAF6 may be a potential target in therapy for retinoblastoma.

ABSTRACT

Objective:To investigate the antioxidant activity of Maca polysaccharides in vitro.Methods:A chemical reaction system was established to explore the scavenging activity of Maca polysaccharides within the concentration range of 0.18-5.00 mg ·ml-1on hydroxyl radicals (·OH),superoxide anion free radicals (O2-·) and DPPH·,and then the total antioxidant capacity was calculated. The protective effects of Maca polysaccharides on H2O2-induced damage in SH-SY5Y cells were determined. SH-SY5Y cells were divided into the control group,H2O2model group and Maca polysaccharide groups(25,50,100 μg·ml-1). In the Maca polysaccharide groups,SH-SY5Y cells were pre-protected by Maca polysaccharides for 24 h, and then incubated in the presence of 300 μmol·L-1H2O2for 6 h. The detection index was SH-SY5Y cell viability detected by MTT assay. Results:Maca polysaccharide within the concentration range of 0.18-5.0 mg·ml-1all exhibited strong scavenging activity on·OH,O2-· and DPPH·in a dose-dependent manner. When the concentration of Maca polysaccharides reached 2.5 mg·ml-1,the scavenging rate was 60.36% for DPPH·,34.66% for O2-·and 36.01% for·OH,the total antioxidant activity was equivalent to 0.179 μmol FeSO4. Maca polysaccharides at the concentration of 25, 50 and 100 μg·ml-1all showed significant protective effects on H2O2-induced injury in SH-SY5Y cells, and the cell survival rate was 61.71 ± 2.45%,61.73 ± 4.51% and 60.98 ± 3.12%, respectively,which were all significantly higher than those in the model group (P < 0.05). Conclusion:Maca polysaccharides has good antioxidant activity,which is worthy of further research and development as a natural antioxidant.

ABSTRACT

Based on the relation of efficacy and toxicity, this study mined the dosage rules and characteristics of Aconitum herbs in oral prescriptions from 48 traditional ancient books from Eastern Han dynasty to Qing dynasty, to provide the basis for strengthening the clinical risk pharmacovigilance. In the 48 traditional ancient books, 4 521 prescriptions with clear daily oral dosage were included to establish a database. SPSS 20.0 software was used for statistics and analysis of the daily dosage characteristics with different kinds of herbs, indications, dose forms, processing, use in special population, and other aspects. The results showed that 67% prescriptions contained Aconitum carmichaeli(Fuzi), and 90% of them was less than 14.87 g·d⁻¹; The dosage of A. carmichaeli(Chuanwu) and A. kusnezoffii(Caowu) were less than 3.14 g·d⁻¹. In the prescriptions for treating typhoid, epidemic, edema and phlegm, the dosage of Aconitum was larger. There dosage in the decoction and vinum was significantly higher than that in the pill and powder. With the dynastic evolution, the dosage of Aconitum herbal medicines prescriptions and the application percentage of superposition drug also had decreased. For the special populations that with different metabolism process, such as old people, children, pregnant and lactating women, the application of Aconitum was not only with relatively small ratio, but also with lower dose. Therefore, based on the data-mining of ancient books, the dosage of Aconitum should not exceed the limit prescribed by the current China Pharmacopoeia, and also should be strictly controlled by considering various factors, which will ensure the balance of efficacy and toxicity.

Objective To detect the expression of IL-17 in renal transplant recipients by Luminex and evaluate the relationship between the level of serum IL 17 and early acute renal allograft rejection.Methods 38 kidney transplant recipients and healthy controls (HC,healthy volunteers,n =20) were selected in this study from January 2009 to October 2011.All patients were divided into two groups according to their allograft outcome as acute rejection group (ARG,n-18) and non-rejection group (NRG,n=20).The expression of serum IL-17 was detected by Luminex technique in two groups of kidney transplant recipients and HC.To evaluate the correlation between the level of serum IL-17 and early acute renal allograft rejection.Results The mean level of IL-17 in all renal transplant recipients 1.3 ± 1.9 pg/ml at the pre-transplantation was significantly lower than that in HC (6.9± 8.5 pg/ml,t=3.968,P<0.001).The results highlighted that the level of serum IL-17 in ARG 3.4±5.8 pg/ml was significantly higher than that in NRG (0.5±0.4 pg/ml) on the 7th days post Kidney transplantation (post KTx,t=2.242,P =0.031).Kaplan-Meier survival analysis showed that the probability of rejectionfree survival in the higher levels group of IL-17 on the 7th days post-KTx was significant lower than that in the lower levels group (P<0.001).The results of receiver operating characteristic curve showed that the sensitivity and specificity of the combined IL-17 to predict acute rejection were 66.67% and 100%,respectively.Conclusion The serum IL-17 levels in renal transplant recipients on the 4th and 7th post-KTx days can predict early renal transplant rejection.

ABSTRACT

Objective To investigate the effect of stem cells transplantation on immune function,liver function and related indexes in the patients with end-stage liver disease(ESLD).Methods A total of 163 cases of ESLD in Nanyang Municipal Central Hospital of Affiliated Hospital of Zhengzhou University were selected and divided into 2 groups by the randomized single blind method.Eighty-one cases in the control group were given the conventional symptomatic treatment,while 82 cases in the observation group received bone marrow mesenchymal stem cell(BMSC) transplantation based on the control group.The changes of immune function,liver function,alpha fetoprotein(AFP),rate of prothrombin activity(PTA) and plasma total protein(TP) level before and after treatment were observed in the two groups.Results The immune function indexes CD3+,CD4+,CD8+,CD4+/CD8+,TP and PTA levels after treatment in the observation group were significantly higher than those before treatment and in the control group (P<0.05),while the levels of AFP,alanine aminotransferase (ALT),aspartate aminotransferase (AST) and total bilirubin (TBIL)were lower than those before treatment in the same group and the control group(P<0.05).There was no statistically significant difference in complication occurrence rate between the two groups(P>0.05).Conclusion BMSC transplantation for treating ESLD can improve the immune function,improves the liver function and reduces the AFP level.

ABSTRACT

Objective To investigate the protective effect of Qingkailing (QKL) in cardiac muscle's injury induced by endotoxin and discuss the mechanism from the inflammatory factors expression and free radical metabolism. Methods A total of 48 male ICR mice were divided into normal group, model group, low dose group and high dose group, 12 mice in each group. The QKL(9 ml/kg) was administered via gavage daily for 4 days in low dose group, the QKL (18 ml/kg) was administered via gavage daily for 4 days in high dose group, the equivalent volume of saline was administered via gavage daily for 4 days in normal group and model group. At the fifth day all groups except normal group, received intraperitoneal injection of LPS 0.2 ml (40 mg/kg), and the normal group received equivalent volume of saline. Intragastric administrated again 0.5h, 8h and 20 h after the model establishment. We took blood from hearts 1 hour after the last administration. The QR-PCR was used to detect the expression of inflammatory factors. The Elisa was used to detect IL-1β, IL-6, TNF-α, MDA, SOD and GSH-Px. Results Compared to the model group, the content of TNF-α (68.75 ± 7.73 pg/ml, 62.03 ± 16.09 pg/ml vs. 116.06 ± 21.06 pg/ml), IL-1β (110.84 ± 40.61 pg/ml, 105.51 ± 38.21 pg/ml vs. 167.53 ± 54.82 pg/ml) and IL-6 (68.78 ± 20.57 pg/ml, 59.71 ± 13.59 pg/ml vs. 108.80 ± 28.21 pg/ml) in low dose group and high dose group were significantly decreased (P<0.01). The expression of TNFα mRNA (1.42 ± 0.15, 1.30 ± 0.46 vs. 3.00 ± 0.82),IL-1β mRNA (1.20 ± 0.57, 1.01 ± 0.40 vs. 2.32 ± 1.39) and IL-6 mRNA (1.53 ± 1.10, 1.16 ± 1.09 vs. 4.12 ± 2.23) in low dose group and high dose group were significantly decreased (P<0.01 or P<0.05). The content of MDA (10.64 ± 2.91 nmol/mg, 11.36 ± 3.02 nmol/mg vs. 15.21 ± 2.31 nmol/mg) in low dose group and high dose group were significantly decreased (P<0.01). The content of SOD (282.32 ± 35.90 U/mg, 325.07 ± 34.76 U/mg vs. 249.01 ± 45.22 U/mg) and GSH-Px (48.26 ± 17.13 U/g, 49.66 ± 22.11 U/g vs. 26.47 ± 20.37 U/g) in low dose group and high dose group were significantly increased (P<0.01). Conclusions The QKL plays a protective role in myocardial injury induced by endotoxemia. Its mechanism may be associated with down-regulation of expression of inflammatory factors, reducing free radicals and improvement of antioxidation.
