This study was aimed to observe effect of pomegranate leaf tannin and ellagic acid on primary rat adipocyte differentiation and lipid metabolism-related factor expression. Primary rat preadipocyte was in vitro cultured to observe the effect of pomegranate leaf tannin and ellagic acid on lipid fat cells as well as mRNA expression of its related factor. The results showed that pomegranate leaf tannin and ellagic acid had obvious inhibition effect on fat formation in fat cells. It had certain inhibition effect on activities of lipoprotein lipase (LPL) and glucose-3-phosphate dehydrogenase (GPDH). It promoted fat decomposition and reduced intracellular lipid content. It upregulated PPARγ and fatty acid-binding protein (aP2). It downregulated obese (ob) gene level. It was concluded that pomegranate leaf tannin can inhibit fat generation of fat cells and promote fat metabolism. Ellagic acid was its main active ingredient, which had the same effect as pomegranate leaf tannin.

This study was aimed to observe the effect ofpomegranate leaf tennis and Ananas coumosus leaf phenols on the growth of lactating mice through breast milk. Intragastric administration of different doses of drug was given to maternal mice. The general condition of newborn mice, body weight, tail length and organ coefficient of liver-related factors regulating the expression of lipid metabolism were observed. The results showed that both pomegranate leaf tennis and A. coumosus leaf phenols can obviously affect the growth and development of newborn mice through breast milk. And the effect of pomegranate leaf tennis was stronger than A. coumosus leaf phenols. Meanwhile, it obviously downregulated the expression of liver-related lipid metabolism enzymes in newborn mice. It was concluded that pomegranate leaf tennis and A. coumosus leaf phenols can affect the growth and development of newborn mice through breast milk. Its effect was related to the influence of lipid metabolism enzyme in the liver. Attention should be paid on taking this medication during lactation. Its clinical significance still required in-depth study.

This article was aimed to study the quality control of pineapple leaf in order to further develop the appli-cations of pineapple leave as medicinal resources. The tissue structure of pineapple leaf was observed by tissue biop-sy assay. Thin-layer chromatography (TLC) was employed on the qualitative identification of ananasate in the leave. The p-coumaric acid and ananasate were detected with high-performance liquid chromatography (HPLC) assay in the content determination. The results showed that pineapple leaf can be divided into the upper and lower leaf epidermis with stoma under microscope observation. Ananasate of the leave can be indentified clearly by TLC. HPLC method can accurately detect the content of p-coumaric acid and ananasate of pineapple leave. There are different contents of p-coumaric acid and ananasate of pineapple leave in different origins. In Y unnan province, the contents of p-coumaric acid and ananasate of pineapple leave are the highest; while the contents of p-coumaric acid and ananasate in Guangxi province are the lowest. It was concluded that ananasate can be used in the quality identification. The p-coumaric acid and ananasate can be used in the quantitative determination in the better control of the quality of pineapple leaf.

Objective To study the expression of metallothioneiu (MT)and Fas ligand (FasL) in rectal carcinoma and their association with metastasis to lymph node and liver. Methods Immunohistochemistry method and quantitative RT-PCR technique were used to assay the expression of MT and FasL at protein and mRNA levels in 85 cases of rectal carcinoma. The data of each group were compared and analysed by statis-tics. Results The rates of MT expression in primary foci, normal rectal mucosa, lymph node metastasis and hepatic metastasis were 57.3% ,29.6% ,79.5% and 61.8% respectively. And the rates of FasL expression were 45.8%, 17.8% ,63.5% and 90.3%, respectively. The positive rates of MT and FasL in primary foci, hepatic and lymph node metastasis were higher than that in normal mucosa (X~2 =33. 1322,56. 7142,P < 0.01). Among clinical stages, the positive rates of MT and FasL in C and D were higher than that in A and B (X~2 = 18. 8372,21. 5823 ,P <0.01). And higher rates of MT and FasL expression were detected in low differentiation adenocarcinoma and mucus adenocarcinoma than in middle-high differentiation adenocarcino-ma(X~2 = 11.2146,9.3136,P < 0. 05). High MT mRNA level was found in lymph node metastasis and high FasL mRNA level in hepatic metastasis. Conclusions The detection of MT and FasL expression was useful in clinic to predict lymph node metastasis and early diagnosis of liver metastasis of rectal carcinoma respec-tively. Assay of MT and FasL expression has prognostic values for rectal carcinoma patients.

Objective To study the SRSF2 mutations in acute myeloid leukemia (AML) patients by using high-resolution melting analysis (HRMA). Methods PCR-HRMA analysis was performed to screen SRSF2 mutations in 140 cases with AML, and the direct DNA sequencing was used to confirm the HRMA results. Results Five percent (7/140) of AML patients were found with heterozygous SRSF2 mutations, including one case of P95R mutation, two case of P95L mutation, and four cases of P95H mutation, the above mutations were confirmed by direct DNA sequencing. The maximal sensitivity of HRMA in detecting SRSF2 mutation was close to 10%. There were no difference in gender, age and blood parameters among cases with or without SRSF2 mutations (P > 0.05). The overall survival (OS) of patients with SRSF2 mutations was inferior to those without SRSF2 mutations in AML patients (P=0.016). Conclusions HRMA analysis was a convenient, rapid, specific, high-throughput technique for scanning of SRSF2 gene mutations in AML patients. SRSF2 mutation may predict the adverse prognosis in AML patients.
