ABSTRACT
Objective:To observe the effect of speech training based on mirror neuron theory on children with functional articulation disorder (FAD).Methods:Fifty children with FAD were randomly divided into a training group and a control group, each of 25. Both groups received 30 minutes of conventional speech training 5 times a week for 24 weeks, while the training group was additionally given 20 minutes of speech training based on mirror neuron theory simultaneously. Before and after the intervention, both groups were evaluated using the articulation speech ability assessment scale and the oral motor ability assessment scale.Results:Before the treatment, there were no significant differences between the 2 groups in any of the measurements. After the treatment, significant improvement was observed in all of the measurements for both groups, but at that point the training group′s articulation, motor ability of the lower jaw, tongue and lips were all significantly superior to the control group′s averages.Conclusions:Speech training based on mirror neuron theory can significantly improve the articulation, intelligibility and oral motor functioning of children with functional articulation disorder.
ABSTRACT
This paper was aimed to observe the effect of Yisui Shengxue (YSSX) granules on CD4+ CD25 + regulatory T cells (Treg cells) and its treatment mechanism in aplastic anemia (AA) rats.Male SD rats were selected and randomly divided into different groups according to their weight.In the model group,subcutaneous injection of benzene (1 mL· kg-1)was given every other day for 7 consecutive weeks.Ten days before the rats were sacrificed,intraperitoneal injection of CTX (25 mL · kg-1) was given for 3 consecutive days.On the 4th week,model rats were divided into the model group,stanozolol group,and the YSSX granules group.Intragastric administration of corresponding drug was given.Same volume of normal saline was given to the normal group and the model group.At the end of the experiment,WBC,RBC,HGB and PLT in peripheral blood were detected.Blood smear and bone marrow smear were prepared.The Foxp3 protein expression of Treg cells in spleen tissues was detected by immunohistochemistry (IHC).RT-PCR was used to detect the Foxp3 mRNA expression in bone marrow tissues.The results showed that compared with the normal group,WBC,RBC,HGB and PLT in the model group were significantly reduced (P ＜ 0.01).The blood smear showed poor permeability of blood cells,reduced WBCs,and increased degenerated cells.The bone marrow smear indicated significantly increased fat drops,significantly reduced hematopoietic cells,and increased nonhematopoietic cells.After the treatment of YSSX granules,WBC,RBC,HGB and PLT were significantly increased (P ＜ 0.01).Both the blood smear and bone marrow smear showed cell permeability improvement,cell form returns to normal,fat drops significantly reduced,significantly increased hematopoietic cells,significantly increased Foxp3 protein expression in spleen tissues and Foxp3 mRNA expression in bone marrow tissues (P ＜ 0.01).It was concluded that YSSX granules can upregulate both gene and protein expression of Foxp3,regulate AA immune function in order to improve the AA immune environment,promote the recovery of bone marrow hematopoietic function,which played an important role in AA treatment.
ABSTRACT
This paper was aimed to study the renal protective effect of Tang-Shen-Ning (TSN) on diabetic nephropathy (DN) KKAy mice by inhibiting the Notch/snail1 signal transduction pathway.A total of 30 KKAy mice,which were fed with mice-dedicated food for 10 weeks and with the blood glucose over 16.7 mmol· L-1,24-hour urinary albumin larger than 0.4 mg,were made into the DN model.The DN mice were randomly divided into the model group,irbesartan group and TSN group according to their blood glucose and weight.Intragastric administration of medication was given.A total of 10 female C57BL/6J mice were selected as the control group.The general condition,body weight and 24-hour urinary protein quantitation were detected.After 16-week intervention,mice were sacrificed.Levels of blood glucose,blood urea nitrogen (BUN) and serum creatinine (Scr) were detected.HE and Mallory staining were applied to renal tissues.In situ hybridization (ISH) and western blotting were used to detect the Notch/snail 1 pathway,α-SMA,E-Cadherin protein and mRNA expression in renal tissues.Statistical analysis was made by SPSS20.0 software.The results showed that compared with the model group,the rats' general conditions were improved;body weight and 24-hour urinary protein quantitation were significantly decreased (P＜0.01);contents of BUN and Scr were reduced (P＜0.01,P＜0.05).The pathological staining showed significantly reduction on renal interstitial fibrosis.The Notch/snail1 pathway,protein and mRNA expression of α-SMA were significant reduced with statistical significance (P＜0.01);protein and mRNA expression of E-Cad protein were significant increased with statistical significance (P＜0.01).It was concluded that TSN can protect the renal function of DN,delay the disease progression of DN,and inhibit epithelial-mesenchymal transdifferentiation (EMT) of renal tubular epithelial cells and renal interstitial fibrosis.Furthermore,the inhibition on EMT may be through the regulation of the Notch/snail1 pathway.

ABSTRACT
For unresectable advanced hepatocellular carcinoma (HCC),besides sorafenib,alternative drugs and treatment modalities are required.Clinical studies of hepatic arterial infusion chemotherapy (HAIC),transcatheter arterial chemoembolization (TACE),and system chemotherapy have shown favorable efficacy and tolerance in advanced HCC patients.In addition,the potential efficacy of sorafenib combined with focal treatment is also an interesting issue.As more therapies become available,decision-making for treating advanced HCC becomes increasingly complex.In our opinion,diverse treatment modalities should be utilized for the best interest of patients.Based on predictive biomarkers,we should develop a precise patient stratification system to select suitable candidates for each treatment modality in future studies,as is useful for improving prognosis of patients with advanced HCC.
ABSTRACT
This study was aimed to observe the influence of β-sitosterol (BSS) on estrogen receptor (ER) positive the human breast cancer cell line T47D and to study its mechanisms. ER antagonist ICI182 780 was employed to observe the influence on the proliferation. Proliferations of T47D cells influenced by different concentrations of BSS were analyzed by MTT assay. Cell cycle analyses were examined by flow cytometry. The protein expression of cyclin D1 was measured by western blot analysis and cyclin D1 mRNA was quantified by real-time PCR assay. The results showed that BSS in high dose exhibited significant inhibitory effects that were partly antagonized by ICI182 780 and decreased the proliferative index on T47D cells. However, BSS in low dose obviously promoted the proliferation that was completely inhibited by ICI182 780 and increased the proliferative index on T47D cells. The mRNA and protein levels of cyclin D1 were increased in low-dose BSS. The effect was blocked by ICI182 780. It was concluded that BSS in low concentration had phytoestrogenic effect by up-regulating the expression of cyclin D1 via ER pathway.
ABSTRACT
Objective To investigate the effect of curcumin on the expression of nuclear transcription factor (NF-kappa B) and its inhibitory protein (Iκ-Bα) in liver cancer cells (Hepg-2) induced by TNF-α, and explore its effect on non-alcoholic steatohepatitis. Methods The cells were divided into normal group, TNF-alpha group, and different concentrations of curcumin treatment group. MTT and Western blotting were used to assay curcumin’s effect on Hepg-2 proliferation activity and changes of NF-κB and Iκ-Bα’s in Hepg-2. Results Compared with the normal group, TNF-αgroup enhanced NF-κB and Iκ-Bαexpression, but the increase of Iκ-Bα had no statistical significance (P>0.05). Curcumin treatment group’s NF-κB expression was significantly weakened than TNF-α group, while Iκ-Bα was significantly enhanced than that of TNF-α group. Conclusion Curcumin can antagonize NF-κB inflammatory signaling pathway activation induced by TNF-α, thus reduce the inflammatory injury of the liver cells.

Objective To investigate the effect of gender factors on the reduction of ischemia-reperfusion (I/R) injury by sevoflurane postconditioning in isolated rat cardiomyocytes. Methods Sixty 2-month-old SD rats (30 male, 30 female) were used in this study. Male rats were randomly assigned into 2 groups (n = 15 each):control group (group MC) and sevoflurane postconditioning group (group MS). Female rats were also randomly assigned into 2 groups (n= 15 each): control group (group FC) and sevoflurane postconditioning group (group FS).The rats were anesthetized with intraperitoneal pentobarbital 60 mg/kg. Their hearts were excised and perfused in a Langendorff apparatus with K-H solution saturated with 95% O2-5% CO2 at 37 ℃. I/R was produced by 40 min of global ischemia followed by 120 min of reperfusion. Control groups received perfusion with K-H solution saturated with O2 . Sevofiurane postconditioning groups received 10 min of perfusion with K-H solution saturated with 3%sevoflurane and O2 and then 110 min of perfusion with K-H solution saturated with O2 . HR, left ventricular enddiastolic pressure (LVEDP) and left ventricular developed pressure (LVDP) were measured before ischemia and during reperfusion. Coronary effluent was collected at 5 min of reperfusion for determination of LDH activity and infarct size. The total Akt (t-Akt) and phosphorylated Akt (p-Akt) expression in cardiomyocytes was detected. The ratio of p-Akt to t-Akt (p-Akt/t-Akt) was calculated. Results LVDP, p-Akt expression and p-Akt/t-Akt were significantly higher, LVEDP and LDH activity were significantly lower, and the infarct size was smaller in group MS and FC than in group MC (P ＜ 0.05). LVDP was significantly lower, LVEDP and LDH activity were significantly higher, and the infarct size was larger in group FS than in group MS. There was no significant difference in LVDP and LVEDP between group FC and FS (P ＞ 0.05). Conclusion There are gender differences in the reduction of I/R injury by sevoflurane postconditioning in isolated rat cardiomyocyes, the protective effect is stronger in male rats than in female rats, and the differences may be related to the activation of Akt.

ABSTRACT
OBJECTIVE: To investigate the changes of connective tissue growth factor (CTGF) protein and CTGF mRNA in kidney tissue of rats with adriamycin (ADR)-induced nephropathy and to study the effects of compound Biejia Ruangan tablet (CBJRGT), a traditional Chinese herbal medicine for treatment of liver fibrosis. METHODS: A rat model of ADR-induced nephropathy after one-sided nephrectomy was established. Forty-five Wistar rats were randomly divided into 5 groups: normal control group, sham-operated group, untreated group, lotensin-treated group and CBJRGT-treated group. Pathological changes of the kidney tissue were observed by microscopy after 10-week drug administration. The expressions of CTGF protein and CTGF mRNA in the kidney tissue were measured by the methods of immunohistochemistry and in situ hybridization. RESULTS: The expressions of CTGF protein and CTGF mRNA in the normal and sham-operated groups were decreased in the intracytoplasm of glomerular mesangial cells, renal tubular epithelial cells and interstitial cells. Compared with the sham-operated group, the expressions of CTGF protein and CTGF mRNA in the untreated group were markedly increased and the development of renal fibrosis in the untreated group could be observed. CBJRGT could significantly decrease the expressions of CTGF protein and CTGF mRNA, and there was no significant difference between CBJRGT-treated group and lotensin-treated group. CONCLUSION: CBJRGT may suppress the development of fibrosis through down-regulating the expressions of CTGF protein and CTGF mRNA.

ABSTRACT
Objective To study the expression of Gal?-1,4-GlcNAc group in human normal brains and astrocytomas. Methods The protein extracts from human normal brains and astrocytomas were subjected to sodium dodecyl sulfate polyacrylamide gel electropheresis(SDS-PAGE),then were stained with Coomassie Brilliant blue(CBB).In addition,the expression of Gal?-1,4-GlcNAc group was studied by ricinus communis agglutinin-I(RCA-I) lectin blot and lectin histochemistry with RCA-I respectively. Results By comparison,CBB staining showed that the protein components from normal brains were similar to those from astrocytomas.However,by RCA-I lectin blot and histochemistry assay,it was found that the expression of Gal?-1,4-GlcNAc was more extensive in astrocytomas than normal brains.It was surprising that a major 61?kD protein was galactosylated in astrocytomas but not in normal brains.Ratio of RCA-I stained cells was 8% in human normal brains,while 15%,21%,28% and 41% in astrocytomas Ⅰ,Ⅱ,Ⅲ and Ⅳ respectively.Conclusion The expressions of Gal?-1,4-GlcNAc groups in astrocytomas were more than those in normal brains,which suggested that Gal?-1,4-GlcNAc group might be related to the malignant degree of astrocytomas.
