RESUMO
The purpose of this study was to clone and characterize the ZFP36L1 (zinc finger protein 36-like 1) gene, clarify its expression characteristics, and elucidate its expression patterns in different tissues of goats. Samples of 15 tissues from Jianzhou big-eared goats, including heart, liver, spleen, lung and kidney were collected. Goat ZFP36L1 gene was amplified by reverse transcription-polymerase chain reaction (RT-PCR), then the gene and protein sequence were analyzed by online tools. Quantitative real-time polymerase chain reaction (qPCR) was used to detect the expression level of ZFP36L1 in intramuscular preadipocytes in different tissues and adipocytes of goat at different differentiation stages. The results showed that the length of ZFR36L1 gene was 1 224 bp, and the coding sequence (CDS) region was 1 017 bp, encoding 338 amino acids, which was a non-secretory unstable protein mainly located in nucleus and cytoplasm. Tissue expression profile showed that ZFP36L1 gene was expressed in all selected tissues. In visceral tissues, the small intestine showed the highest expression level (P < 0.01). In muscle tissue, the highest expression level was presented in longissimus dorsi muscle (P < 0.01), whereas the expression level in subcutaneous adipose tissue was significantly higher than that in other tissues (P < 0.01). The results of induced differentiation showed that the expression of this gene was up-regulated during adipogenic differentiation of intramuscular precursor adipocytes (P < 0.01). These data may help to clarify the biological function of the ZFP36L1 gene in goat.

Objective:To explore the effect of Plantaginis semen on the expressions of AQP4 gene and protein in small intestine of diarrhea rats. Methods:Sixty Sprague-Dawley male rats were randomly divided into normal control group, model control group, hydrochlorothiazide group, and low-, medium-, and high-dose Plantaginis semen groups. Intragastric administration of Senna (20 ml/kg) was implemented in the morning for 5 groups except the normal group. The rats in the low-, medium-, and high-dose Plantaginis semen groups were intragastrically administered with 0.95, 1.9, 3.8 g/kg Plantaginis semen formula granule solution, while the rats in hydrochlorothiazide group were given hydrochlorothiazide suspension 9 mg/kg by gavage according to 1 ml/100 g body weight for 14 days. The loose stool rate, average ranking of loose stool, and diarrhea index were compared according to the fecal traits and stool times after 14 days of treatment, and the small intesine tissue were collected. Hematoxylin-eosin (HE) staining to observe the pathological morphological changes in small intestine, and Quantiative Real-time PCR and Western blot were applied to detect the gene and protein expressions of AQP4. Results:Compared with the model group, the loose stool rate (50.89% ± 6.17%, 41.14% ± 4.48%, 36.37% ± 4.81 % vs. 67.45% ± 7.35%), the average ranking of loose stool (2.16 ± 0.34, 1.73 ± 0.28, 1.52 ± 0.25 vs. 2.63 ± 0.29), and the diarrhea index (1.10 ± 0.19, 0.71 ± 0.11, 0.57 ± 0.12 vs. 1.77 ± 0.24) of rats in each group of Plantaginis semen significantly decreased ( P<0.05); the degree of intestinal mucosal injury, hyperemia and neutrophil infiltration were alleviated; the expressions of AQP4 mRNA (0.48 ± 0.10, 0.69 ± 0.12, 0.97 ± 0.15 vs. 0.21 ± 0.03), and the protein of AQP4 (0.59 ± 0.08, 0.64 ± 0.09, 0.78 ± 0.11 vs. 0.32 ± 0.05) in the small intestine tissue of Plantaginis semen groups significantly increased ( P<0.05). Conclusions:Plantaginis semen has antidiarrheal effect, and its mechanism is related to up-regulation the gene and protein expressions of AQP4, addition of water absorption and promotion of water and fluid metabolism.
RESUMO
OBJECTIVE:To observe the effects of Breviscapine injection on serum copeptin,NT-proBNP and ischemia modi-fied albumin (IMA) level and hemorheology indexes in patients with acute cerebral infarction. METHODS:Data of 132 patients with acute cerebral infarction were selected and randomly divided into observation group(66 cases)and control group(66 cases). Control group received 1 Aspirin enteric-coated tablet,qd + 20 ml Muscular amino acids and nucleosides injection adding into 500 ml 0.9% Sodium chloride solution,intravenous infusion,qd + 4 ml Ozagrel injection adding into 250 ml Sodium chloride solution, intravenous infusion,qd. Observation group was additionally given 5 ml Breviscapine injection adding into 250 ml 0.9% Sodium chloride solution,intravenous infusion,qd. 7 d ag was regarded as 1 treatment course,it lasted for 2 courses. Copeptin,NT-proB-NP,IMA levels (showed by serum ACB value) and changes of related hemorheology indexes before and after treatment in 2 groups were observed. RESULTS:Before treatment,there was no significant difference in Copeptin,NT-proBNP,serum ACB val-ue,whole blood viscosity,plasma viscosity,hematocrit,ESR and fibrinogen levels in 2 groups(P>0.05);after treatment,Co-peptin,NT-proBNP,whole blood viscosity,plasma viscosity,hematocrit,ESR and fibrinogen levels in 2 groups were significant-ly lower than before,and observation group was lower than control group,while serum ACB value was significantly higher than be-fore,and observation group was significantly higher than control group,the differences were statistically significant(P<0.05). CONCLUSIONS:Based on conventional treatment,Breviscapine injection can significantly improve the copeptin,NT-proBNp and IMA levels,and improve hemorrheology.
