International Journal of Traditional Chinese Medicine 2012;34(2):126-129
Objective To observe the therapeutic effect of red peony root decoction (RPRD) on model rats with acute pancreatitis (AP),and the effect on the expression of NF-κB,TNF-α and IL-6.Methods Forty SD rats were randomly divided into five groups:normal control group (group A),AP model groups (group B,24 h; group C,72 h) and RPRD treatment groups (group D,24 h; group E,72 h).There were 8 rats in each group.The AP models were induced by intraperitoneally injecting with L-arginine.After the model was established,rats of group B and group C were treated with intra-gastric instillation of NS,and rats in group D and group E with RPRD.At 24 and 72 hours after induction of AP,rats in each group were sacrificed and blood samples were taken for the measurement of serum amylase,TNF-α and IL-6.The expression of NF-κB p65 protein in the pancreas were detected by Western Blot,and pathological status of the pancreas were analyzed.Results The serum amylase level in group B and group D was significantly higher than that in group A (P<0.05),and the level in group D was obviously lower than that in group B (P<0.05).The serum amylase level in group C and group E was decreased,and there was no difference between group A (P>0.05).The pathological severity and pathological scores of the pancreas in group D and group E were more lighter than those in group B and group C (P<0.05).The level of serum TNF-α and IL-6 was significantly decreased in RPRD treatment groups (P<0.05),group D compared with group B,[ (12.54±2.12)pg/ml,(552.88±81.27)pg/ml] vs.[ (20.53±4.16)pg/ml,(1255.75± 118.82)pg/ml]; group E compared with group C,[ (11.01 ±2.02)pg/ml,(582.87± 88.86) pg/ml] vs [ (23.85 ± 5.59) pg/ml,(1366.33 ± 163.16) pg/ml].The expression levels of NF-κBp65 protein in the pancreas of group D and group E were significantly lighter than those in group C at both time points (group D compared with group B,(0.07±0.055) vs (0.71 ±0.029),P<0.05; group E compared with group C,(0.15±0.038) vs (0.65±0.026).Conclusion RPRD may alleviate the pathologic changes in AP
2.Expressions of protein kinase C subtypes in glomerulonephritis and their significance
Journal of Third Military Medical University 2001;23(4):454-456
Objective To investigate the expressions and significance of protein kinase C (PKC) subtype α, β2 and ε in the pathogenesis of glomerulonephritis. Methods Immunohistochemical assays was used to examine the expressions of PKC α, PKC β2 and PKC ε in biopsy specimens of kidney from patients with mesangial proliferative glomerulonephritis (MsPGN) (n=16),nonproliferative golmerulonephritis (nonPGN) (n=12),and in structurally normal kidneys (n=6). Results The PKC β2 expression in the glomerular was significantly higher in MsPGN patients than in nonPGN or normal kidney groups. Conclusion PKC β2 has a close association with MsPGN and might take part in the initiation of this renal disease.
3.Effects of Radix Paeoniae Rubra decoction on the expression of cvtokines in rats with acute pancreatitis
Chinese Journal of Emergency Medicine 2009;18(11):1141-1145
Objective To observe the therapeutic effects of Radix Paeoniae Rubra decoction (RPRD) on a-cute pancreatitis (AP) in rats, and to study effects of RPRD on the expression of NF-κB, TNF-α and IL-6. Method Forty Sprague-Dawley (SD) rats were, randomly divided into five groups: normal control group (group A), AP model groups (group B, 24 h; group C,72 h) and RPRD treatment groups (group D, 24 h;group E,72 h).There were 8 rats in each group. The AP models were induced by intraperitoneally injecting with L-arginine. After the model was estabhshed, rats of group B and group C were treated with inn'a-gastric instillation of NS, and rats in group D and group E with RPRD. At 24 and 72 hours after induction of AP, rats in each group were sacri-riced and blood samples were taken for the measurement of serum amylase. The expression of NF-κB 1065 protein and TNF-α and IL-6 mRNA in the pancreas was detected by Western blotting and real-time quantitative PCR, re-spectively, and the pathological status of the pancreas was analyzed. Results The serum amylase level in group B and group D was obviously increased at 24 hours, and were significantly higher than that in group A (P < 0.05) ; the level in group D was lower thaa that in group B (P < 0.05). the level reduced at 72 hours, and there was no difference between group E and group C (P > 0.05). The pathological severity and the pathological score of pan-creatic tissue in group D and group E at 24 hours and 72 hours were more hghter than those in group B and hours C (P < 0. 05). The expression levels of NF-κB p65 protein (Western blotting) in the pancreas of group D and group E were significantly lighter than those in group B and group C at both time points (group D compared with group B, (0.07 ± 0.006) vs. (0.71 ± 0.029), P < 0.05;group D compared with B, (0.07 ± 0.006) vs. (0.71 ±0.029), P <0.05; group E compared with C, 0.18±0.014 vs. 0.65±0.026, P <0.05). The results of real-time quantitative PCR shown that the expression levels of TNF-α and IL-6 mRNA in model treatment group were significantly stronger than that in RPRD group at the two time points (P < 0.05). Conclusions RPRD is effective for the treatment of AP rats to inhibit the activity of NF-κB. Inhibition of NF-κB offers a promising strategy to treat AP by down-regulating eytokine expression.

6.Ego State Analysis in Stroke Rehabilitation
Chinese Journal of Rehabilitation Theory and Practice 2014;(2):184-187
Because the rehabilitation process is too long and its effect is non-significant, stroke patients are prone to showing over-reliance on their families, being unconfident in their abilities, and they usually miscommunicate with medical staff, in fact, the reason why they have these problems is that they didn't manifest appropriate ego states, so they couldn't communicate with families and medical staff healthily,which is extremely unfavorable for stroke rehabilitation. So-called ego state is individual mentality and corresponding behavior patterns.This paper used ego state concept in transactional analysis theory to describe the change of stroke patients' ego states, and analyze the communication patterns among patients, medical staffs and families, in order to assist patients to be aware of their own ego states, and present them properly, develop healthy communication, and promote the rehabilitation of the disease in the end.
8.Study on effect of total matrines and extracts from Periplaneta americana on negative endometrial cancer cell JEC of progesterone receptors.
China Journal of Chinese Materia Medica 2015;40(11):2210-2213
To study the effect of total matrines and extracts from Periplaneta americana on negative endometrial cancer cell JEC of progesterone receptors. After detecting the effect of total matrine, extracts from P. americana and their combination on JEC cells' growth inhibition, cell cycle, P53 and c-erbB-2 gene protein expressions through MTT, flow cytometry instrument and Western blot method, the author found that, (1) MTT: total matrines and extracts from P. americana could inhibit the growth of JEC cell, with significant increase in the inhibitory effect in the combination group. (2) Flow cytometry instrument: the cell cycle at G0/G1 increased after the treatment with total matrines, the cell cycle at G2/M increased after the treatment with extracts from periplaneta americana, and the ratio of G0/G1 cell cycle in the combination group was significantly higher than the other groups, with inhibition in cell growth and statistical difference in inter-group comparison (P < 0.05). (3) Western blot: the expression level of P53 increased and c-erbB-2 decreased after the treatment with total matrines, extracts from P. americana and their combination on JEC cell, with statistical difference in inter-group comparison (P < 0.05). The above results suggested that total matrines, extracts from P. americana and their combination could induce cell cycle arrest and inhibit the growth of JEC cell by up-regulating P53 and down-regulating the c-erbB-2 level.

10. Enoyl-coenzyme A hydratase, short chain 1 involved in promoting the proliferation of hepatocellular carcinoma HepG2 cells
Tumor 2013;33(5):422-427
Objective: To investigate the effect of ECHS1 (enoyl-coenzyme A hydratase, short chain 1) on the proliferation of hepatocellular carcinoma HepG2 cells. Methods: The recombinant plasmid pGPU6/GFP/siRNA-ECHS1 for ECHS1 gene interference was transfected into HepG2 cells. The HepG2 cells with stable ECHS1 gene interference were screened by puromycin. The expression level of ECHS1 protein in HepG2 cells was detected by Western blotting. The proliferative ability of HepG2 cells after transfection with pGPU6/GFP/siRNA-ECHS1 was detected by CCK-8 (cell counting kit-8) assay and BrdU (5-bromo-2'-deoxyuridine) assay. The expression levels of ERK (extracellular signal regulated kinase), p-ERK (phosphorylated-ERK), cyclin D3 and cyclin D1 were detected by Western blotting. Results: The HepG2 cells with stable ECHS1 gene interference were successfully established. The expression level of ECHS1 protein in HepG2 cells after transfection with pGPU6/GFP/siRNA-ECHS1 was significantly lower than that in the blank control cells (HepG2 cells without transfection) and the negative control cells (HepG2 cells transfected with pGPU6 vector) (P < 0.05). As compared with the negative control cells, the proliferative ability was significantly inhibited (P < 0.05) and the expression levels of p-ERK, cyclin D3 and cyclin D1 proteins were lower in HepG2 cells after transfection with pGPU6/GFP/siRNA-ECHS1 (P < 0.05). Conclusion: ECHS1 may promote the proliferative ability of HepG2 cells via enhancing the expression levels of p-ERK, cyclin D3 and cyclin D1. Copyright © 2013 by TUMOR.
