Objective To establish a method of quality control for compound Cornu cervi degelatinatum tablets. Methods Thin layer chromatography ( TLC ) was used for qualitative identification of Lonicerae Japonicae Caulis and Pyrola Herba in the preparations. High performance liquid chromatography was used to determine the content of loganin and chiratin in Lonicerae Japonicae Caulis and monotropein in Pyrola Herba. Results The TLC spots were clear and specific in the qualitative identification.HPLC determined the content. In the concentration range, monotropein, loganin and chiratin had a good linear relationship with peak area (r>0.999).The mean recovery was 97.2%, 98.4% and 96.0%;RSD was 1.4%, 0.8% and 0.8%. Conclusion The present study employs TLC for quality control and HPLC for quantity control. The methods are simple and accurate, have good reproducibility, and can effectively control the quality of compound Cornu cervi degelatinatum tablets.

Objective To investigate the concentration change of indoxyl sulfate (IS) in blood and the renal expression of renal fibrosis-related factors (transforming growth factor-beta 1, TGF-β1;fibronectin, FN) after administration of mutagenic lactobacilli by oral.Methods A total of 60 male Sprague-Dawley (SD) rats aged 6 weeks was divided randomly into 3 groups.The normal control group (Sham group, n =20) received Sham operation of just incision of skin without kidney removed.The other two groups of rats were renal failure models selected from survivals of the other 40 rats who received real operation with 5/6 of kidney removed.Finally, 35 survived renal-failure rats were divided randomly into 2 groups : pathological control group(Model group, n =17) who were administrated of 2ml sterile saline solution once a day by gavage, and experimental group (lactobacillus bulgaricus (LB) group, n =18) who were administrated of 2 ml mutagenic lactobacilli (1.5 × 108 cfu/ml) once a day by gavage.Eight weeks later, blood specimens were taken to test the concentration of IS with high performance liquid chromatography-fluorescence detection (HPLC-FLU), and urea and creatinine by automatic biochemical analyzer;moreover, the rats were killed to get kidney tissues for pathological examination.Results The levels of serum IS, urea, and creatinine were statistically significantly different between two groups (P ＜ 0.05).Both the levels of renal tubular damage and renal interstitial fibrosis were both lessen in the experimental group compared to the model group (P ＜0.05).TGF-β1 and FN expressions in renal tissues were significantly decreased (P ＜0.05).Conclusions Mutagenic lactobacilli not only reduces serum concentration of IS, urea and creatinine in renal failure rats but lowers the expressions of TGF-β1 and FN in renal tissues.

Purpose To assess left ventricular diastolic function in the patients with essentialhypertension. Methods 25 normotensives,93 hypertensiives without hypertrophy (NLVH) and 47 withhypertrophy (LVH)(LVMI, left ventricular mass index ＞ 124 g/m2 in males and 110 g/m2 in females)underwent 2DE and Doppler echocardiography. Results The ratio of early to late peak velocity (E/A)was 1.21 ± 0.24 in normotensives and 1.03 ± 0.23 in NLVH patients( P ＜ 0.01 ); reversed pulmonaryvenous flow at atrial systole PA wave was (32.7 ± 7.5 ) vs (38.9 ± 8.7) cm/s (P ＜ 0.01 ) in normotensivesand in NLVH patients respectively. The isovolumic relaxation time (IVRT) and left atrial dimension (LAD)have significant differences in three groups ( P ＜ 0. 05 - 0. 001 ). EF value was similar betweennormotensives and NLVH patients, but it was lower in LVH patients ( P ＜ 0.01 ). Conclusions E/Aratio, PA wawe, Pai, IVRT and LAD are sensitive parameters indicating mild diastolic left ventriculardysfunction. Systolic left ventricular function has no change in NLVH patients.

Objective By detecting the mutations spectrum of phenylalanine hydroxylase(PAH)gene in phe-nylketonuria(PKU)patients and their parents. The researchers analyzed the gene mutation features and high - frequency mutations and determined the relationship between the genotype and the phenotype,which would provide a theoretical basis for the early diagnosis and genetic consultation of PKU children in the region. Methods In this study,13 exons and their flanking introns of the PAH gene in 32 PKU patients and their parents from Wuxi and Suqian in Jiangsu province were sequenced by using the next - generation sequencing(NGS)technology. Results Sixty - one mutant sites and 32 mutant genes were detected in 32 PKU patients,and the mutation detection rate was 95. 31%(61 / 64 cases). The variants at c. 721C ﹥ T,c. 1068C ﹥ A,c. 611A ﹥ G,c. 1197A ﹥ T,c. 728G ﹥ A,c. 331C ﹥ T and c. 442 -1G ﹥ A were common mutations in the region with mutation frequency over 5% . What's more,4 novel variants of c. 699C ﹥ G,c. 265C ﹥ T,c. 722G ﹥ A and c. 1194A ﹥ G were found. Of those,c. 699C ﹥ G was not recorded in the PAH variant database and HGMD database and. c. 265C ﹥ T,c. 722G ﹥ A,and c. 1194A ﹥ G were first reported in the Chi-nese population. Genotype - accurate biochemical phenotype correlation by using the Guldberg AV system revealed con-sistency rate of 38. 0%(8 / 21 cases),which the consistency rate between accurate biochemical phenotype and predic-tive phenotype of moderate to severe genotype was 92. 3%(12 / 13 cases),and mild genotype was 50. 0%(4 / 8 cases). Conclusions The PAH gene variants of PKU patients in Jiangsu province are distributed mainly in exons 7,of which the highest frequency gene mutation is c. 721 c ﹥ T. Moreover,one novel variant c. 699C ﹥ G was reported for the first time. The PKU children inherit the PAH mutation gene mainly from both parents. There are definite correlation between the genotypes and phenotypes.

OBJECTIVE: To observe the effects of Modified Rhizoma Alismatis decoction on the expression of aquaporin 8 (AQP8) in liver tissue of hyperlipemia model rats, and to investigate the mechanism of preventing and treating hyperlipemia.METHODS: Total of 60 rats were randomly divided into blank control group (distilled water), model group, positive control group (simvastatin 1. 89 mg/kg) and modified Rhizoma Alismatis decoction high-dose, medium-dose and low-dose groups (29. 56, 14. 78, 7. 39 g/kg, calculated by crude drug), with 10 rats in each group. Those groups were given high-fat diet to induce hyperlipemia model and given relevant medicine intragastrically once a day for consecutive 5 weeks except that blank control group was given normal diet. After administration, the serum contents of TG, TC, HDL-C and LDL-C in rats were detected, and the pathomorphology changes of liver tissue were observed; the mRNA and protein expression of AQP8 in liver tissue were detected. RESULTS: Compared blank control group, the serum contents of TG, TC and LDL-C in model group were increased significantly (P<0. 05 or P<0. 01),while the serum content of HDL-C was decreased significantly (P<0. 01); pathological changes were found in liver tissue, such as irregular cell arrangement and hepatic sinusoidal hyperemia and edema; mRNA and protein expression of AQP8 in liver tissue were increased significantly (P<0. 01). Compared with model group, above indexes of treatment groups were improved significantly (P<0. 05 or P<0. 01); the structure of liver tissue tended to be normal and the fatty degeneration was obviously alleviated. CONCLUSIONS: Modified Rhizoma Alismatis decoction can regulate the mRNA and protein expression of AQP8 in liver tissue so as to play the effects on the prevention and treatment of hyperlipidemia.
