"Huajiao" is dried ripe fruit peel of Zanthoxylum bungeanum or Z. schinifolium, is konwn as geoherbs, especially the "Dahongpao" cultivated in Hanyuan, Maoxian and Jiulong of Sichuan province. However, the genetic basis of Dao-di "Huajiao" is virtually unknown. The transcriptome of the fruit and leaf from Sichuan(Hanyuan, Jiulong, Lixian, Maoxian), Gansu(Wudu) province and Shaanxi(Fengxian) province was sequenced. Trinity de novo assembling resulted in a total of 177 616 unigenes. Through the KEGG, NR, SwissProt, Trembl, KOG/COG, GO, Pfam database comparision 106 644 annotated Unigene finally, 4 574 deferentially expressed genes were found in fruit between Sichuan and other provinces, including 3 740 up-regulated genes and 834 down-regulated genes. Among the up-regulated genes, 27 up-regulated genes were raleted to terpenoids, and 8 up-regulated genes were related to isoquinoline alkaloid bio-synthesis. Furthermore, it was also showed remarkable differences in groups which enrichment ratio of the diffe-rent expressed gene compared. The different expressed genes were annotated by the KEGG database into plant-pathogen interaction, plant hormone signal transduction and phenylpropanoid biosynthesis in fruit and leaf, but isoflavonoid bio-synthesis and betaine bio-synthesis were significantly different in fruit and leaf. The study laid a certain reference basis for comparison of quality and different expressed gene of Z. bungeanum from different groups.

OBJECTIVE:
To determine the effect of Zanthoxylum piperitum extracet (ZPE) on apoptosis and analyze anticancer substances in ZPE, changes in proteins related to apoptosis, and pathological changes in tumors in mouse.
METHODS:
Fifteen 4-week-old female BALB/c nu/nu mice were divided into 3 groups depending on ZPE dose, with 5 in each group. AGS gastric carcinoma cells (1 × 10
RESULTS:
High performance liquid chromatography (HPLC) analysis showed that ZPE contained organic sulfur compounds such as alliin and S-allylcysteine. MTT assay results revealed that ZPE (10-85 µ g/mL) could effectively inhibit the growth of AGS gastric cancer cells at higher concentrations (P<0.05, P<0.01). The annexin V & dead cell staining assay and cell cycle arrest assay confirmed a dose-dependent increase in the apoptosis rate and G
CONCLUSION
ZPE decreases AGS cell proliferation and induces apoptosis by inhibiting Akt and MDM2 expression.

OBJECTIVEZanthoxylum heitzii is a medicinal plant widely used in central Africa for the treatment of many diseases, especially cardiovascular diseases and hypertension. The diuretic effects of crude stem bark extraction were determined and its safety in rats was evaluated.
METHODSThe diuretic effects of crude stem bark extraction of Z. heitzii 250 g ± 10 g) of both sexes. The crude stem bark extraction of Z. heitzii at the doses of 225, 300 and 375 mg/kg was administered to rats at 5 mL/kg body weight. Urine volume was determined 1, 2, 3, 4, 5, 6 and 24 h after administration of the extract. Kinetics of electrolyte elimination in response to a single oral administration dose of acute treatment was measured. The experiments were performed under the same conditions with two synthetic pharmacological diuretics considered as reference (furosemide and hydrochlorothiazide). Urinary and plasma concentrations of sodium and potassium ions were determined using flame photometry. Concentrations of creatinine, urea, glucose, albumin and electrolytes in the plasma and urine samples were evaluated using a two-way digital bidirectional spectrophotometer. The osmolarity of plasma and urine samples was measured by cytometry using an osmometer. Aldosterone was measured by radioimmunoassay.
RESULTSThe plant extract accelerated the elimination of overloaded fluid and increased urine volume and the excretion of Na+, K+ and Cl- 24 h after administration (P<0.05). The increase in elimination of Na+, K+, and Cl- induced by caused alkalinization of the urine, and showed a strong inhibitory effect on carbonic anhydrase and saluretic. These effects were mainly observed at the dose of 375 mg/kg. At the maximum diuretic response, urinary osmolarity decreased significantly (P<0.05) when compared to controls. The stability of aldosterone level, the absence of correlation with the plasma levels of Na+, and increased clearance of free water in the animals treated with indicated that increased diuresis and natriuresis were tubular in origin. No significant (P>0.05) changes were observed in the body temperature of the animals.
CONCLUSIONThe significant increase in urine volume 24 h after treatment followed a dose-response pattern. The excretion of Na+, K+ and Cl- caused a decrease in urine osmolarity. The stability of aldosterone, the absence of correlation with the plasma levels of sodium, and increased clearance of free water in animals treated with aqueous extract suggest that increased diuresis and moderate natriuresis elevation were of tubular origin.
