[Study on mRNA and protein expressions of organic anion transporting polypeptide (oatp2b1) in rats with high fat diet and overstrain induced Pi deficiency syndrome].

OBJECTIVE: To explore roles of mRNA and protein expressions of organic anion transporting polypeptide (oatp2b1) of rats with high fat diet and overstrain induced Pi deficiency syndrome in the transporting of damp turbidity. METHODS: Totally 24 SD rats were randomly divided into three groups, i.e., the normal group, the overstrain group, and the high fat diet group, 8 in each group. After successful modeling, one piece of tissues such as spleen, kidney, liver, lung, stomach, small intestine, and large intestine was taken from each rat. Rats of the overstrain group were bonded by specially made bondage cylinder, 3 h each time on odd days, and forced to swim in cold water (10 +/- 1) degrees C for 7 min on even days alternatively for twelve weeks. Rats in the model group and the normal group were fed with standard routine granular forage for 12 weeks. Rats in the high fat diet group were fed with high fat forage for twelve weeks. All rats drank and ate freely. The mRNA and protein expressions of oatp2b1 were detected in the seven tissues using RT-PCR and Western blot. RESULTS: The mRNA expression of oatp2b1 in liver and kidney tissues of rats in the high fat diet group was higher when compared with that of the normal group and the overstrain group (P < 0.01, P < 0.05). The oatp2b1 mRNA expression in the normal group was sequenced from high to low as liver > lung > spleen > larger intestine > small intestine > kidney > stomach. The oatp2b1 mRNA expression in the overstrain group was sequenced from high to low as liver > lung > larger intestine > spleen > kidney > stomach > small intestine. The oatp2b1 mRNA expression in the high fat diet group was sequenced from high to low as liver > lung > spleen > small intestine > kidney > larger intestine > stomach. The oatp2b1 protein expression in the lung tissue was sequenced from high to low as the overstrain group > the normal group > the high fat diet group (P > 0.05). The oatp2b1 protein expression in the spleen tissue was sequenced from high to low as the high fat diet group > the normal group > the overstrain group (P > 0.05). The oatp2b1 protein expression in the kidney tissue was sequenced from high to low as the normal group > the overstrain group > the high fat diet group (P > 0.05). The oatp2b1 protein expression in the liver tissue was sequenced from high to low as the normal group > the high fat diet group > the overstrain group (P > 0.05). Of them, the oatp2b1 protein expressed extremely less in the stomach, large intestine, and small intestine. The oatp2b1 protein expression in the normal group was sequenced from high to low as lung >spleen > liver, kidney > stomach, larger intestine, and small intestine. The oatp2b1 protein expression in the overstrain group was sequenced from high to low as lung > spleen > kidney > liver > stomach, larger intestine, and small intestine. The oatp2b1 protein expression in the high fat diet group was sequenced from high to low as spleen > lung > kidney > liver > stomach, larger intestine, and small intestine. However, there was no statistical significance among the three groups by pair-wise comparison (P > 0.05). CONCLUSIONS: Kidney and liver might play important roles in the transportation and transformation of damp under the state of Pi deficiency syndrome. Oatp2b1 may be one of the material bases involved in the transportation and transformation of damp turbidity. Pi's function of governing transportation and transformation of damp might not only include the functions of the gastrointestinal tract, but also include partial liver and kidney functions.

The Upregulation of Trophinin-Associated Protein (TROAP) Predicts a Poor Prognosis in Hepatocellular Carcinoma.

Purpose: Trophinin-associated protein (TROAP) is a cytoplasmic protein that plays a significant role in the processes of embryo transplantation and microtubule regulation. However, the relevant survival analysis and cancer progression analysis have not yet been reported. Methods: Eighteen matched pairs of tumor and adjacent non-tumor samples were evaluated to detect the TROAP mRNA level. Immunohistochemistry (IHC) was used to evaluate the TROAP expression in 108 hepatocellular carcinoma patients who underwent surgical resection. Meanwhile, data from the TCGA database was statistically evaluated. Results: In the present study, we detected a significant increase in the TROAP mRNA level in tumor tissues when compared with adjacent non-tumor tissues. Moreover, the upregulation of TROAP was associated with increased serum AFP and GGT; the greater the tumor number was, the larger the tumor size, differentiation grade, and cancer embolus in clinical analysis. In HCC patients, elevated TROAP expression in the primary tumor was positively related to clinical severity, such as poor overall survival and disease-free survival. In addition, both univariate and multivariate survival analysis validated that TROAP expression was a promising independent risk factor for overall survival and disease-free survival in HCC patients. Furthermore, the results derived from the analysis of data from the TCGA database were consistent with previous results. Altogether, our results show that TROAP is a novel crucial regulator of HCC progression and is a potential therapeutic biomarker for HCC patients. Conclusions: Elevated TROAP expression predicted a poor prognosis, and TROAP may serve as a potential biomarker for application in oncotherapy.

[Clinical observation of modified Suan Zao Ren decoction on insomnia of chronic hepatitis B patients].

OBJECTIVE: To explore the effect of modified Suan Zao Ren Decoction (mediation decoction) on insomnia of chronic hepatitis B patients with stagnation of the Liver-Qi and deficiency of blood syndrome. METHODS: Sixty-five patients of chronic hepatitis B with stagnation of the Liver-Qi, deficiency of the spleen and damp-heat syndrome were randomly divided into two groups. Thirty-three patients in the treatment group were treated by modified Suan Zao Ren Decoction, and thirty-two patients in the control group were treated by Surazepam and Diammonium Glycyrrhizinate. The clinical syndromes of insomnia and liver function were observed before and after treatment. RESULTS: After one months of treatment, the main symptoms and signs of insomnia are improved in both groups, stage I and II sleep decreaed significantly while stage Il, IV and rapid eye movement increased in insomniacs after treatment of modified Suan Zao Ren Decoction (P < 0.05). The total effective rate was not significantly different between the two groups (P > 0.05), while the markedly effective rate was significantly different (P < 0.05). In the same time, ALT, AST, TB levels of two groups were obviously decreased (P < 0.01, P < 0.05), AST levels of two groups after treatment were significant different (P < 0.05). CONCLUSION: Modified Suan Zao Ren Decoction is effective for improving sleep composition, and therefore improve the quality of sleep with few side effect. In the same time, it has the function in improving liver function, and can be used to treat chronic hepatitis B patients with insomnia.

[Effection of compositie salviae dropping pill on hyperlipemia patients with phlegm and blood stasis syndrome].

OBJECTIVE: To explore the effect of compositie salviae dropping pill (CSDP) on hyperlipemia patients with phlegm and blood stasis syndrome. METHOD: Hyperlipemia patients were divided randomly into two groups. One group of 40 patients were treated by CSDP, another group of 41 patients were treated by simvastatin. The TC, TG, HDL-C, LDL-C, ApoA and ApoB levels, ALT, r-GT, IL-6, MDA level and SOD activity were determined before and after being treated. RESULT: After 3 months treatment, the TC, TG and LDL-C levels were obviously decreased in two groups (P <0.01, P < 0.05), there is no significant difference between the effective rate of two groups. The ALT, r-GT, IL-8 and MDA levels of treatment group were obviously decreased (P < 0.01, P < 0.05), while the ApoA level and SOD activity increased obviously in those patients (P <0.05, P <0.01, respectively). However, the ALT, r-GT, IL-6, MDA, HDL-C, ApoA level and SOD activity had no significant difference after treatment in control group. CONCLUSION: Our study suggest that CSDP have the function of falling serum lipid level without damaging liver function, its function of protecting liver function might related to its function of improving of anti-oxidation and decreasing of inflammation, the mechanism of CSDP disparting and removing phlem and blood stasis in the processes lipid metabolism need to be studied further.

[Effect of Chinese medicine for resolving dampness on activated and functional T lymphocyte subsets in chronic hepatitis B patients with dampness syndrome].

OBJECTIVE: To explore the relation between the effect of Huashi Decoction (HD) and levels of activated and functional T lymphocyte subsets in chronic hepatitis B (CHB) patients of dampness syndrome (DS). METHODS: Seventy CHB patients were nonrandomly assigned to two groups, the treated group (n = 45) treated by HD and the control group (n = 30) by nucleotide analogies. The clinical efficay was observed and levels of activated and functional T lymphocyte subsets were detected before and after treatment. RESULTS: The peripheral blood levels of CD8+ CD28+ and CD4+ CD28+ T cells were significantly lower in CHB patients than those in the healthy subjects (P < 0.01), which were higher in the treated group after treatment compared with those before treatment (P < 0.05), while the CD8+ CD38+ T cell level was significantly higher in CHB patients than in the healthy subjects (P < 0.05), which was lower in the treated and the control groups after treatment than those before treatment respectively (P < 0.05). No significant difference was found in the markedly effective rate and total effective rate between the two groups (P > 0.05). The levels of CD8+ CD28+ and CD4+ CD28+ T cells increased and the CD8+ CD3+ and CD4+ CD25+ T cell level decreased obviously after treatment in those who acquired marked effectiveness (P < 0.05), while they changed insignificantly in those who did not acquire marked effectiveness (P > 0.05). CONCLUSION: HD is effective in regulating activated and functional T lymphocyte subsets in CHB patients with DS, which might be its mechanism of inhibiting virus replication and eliminating virus.
