Objective To observe the clinical effect of benzene sulfonic amlodipine combined with traditional Chinese medicine (TCM) Yangxueqingnao granules for treatment of patients with hypertensive urgencies (HU) with acute headache, and its effect on serum brain derived neurotrophic factor (BDNF) level.Methods A prospective study was conducted, 186 HU patients with acute headache admitted to the Department of Cardiology in the Affiliated Hospital of Southwest University from January 2014 to December 2016 were enrolled, and they were divided into a control group (90 cases) and an observation group (96 cases) by random number table method. The patients in control group received benzene sulfonic amlodipine (10 mg, once a day) and the patients in observation group were additionally given Yangxueqingnao granules (4 g, 3 times a day for consecutive 7 days) on the basis of treatment in control group. The mean arterial pressure (MAP), the nature and location of headache and the levels of serum BNDF were examined before and after treatment and compared between them in the two groups, the degree of headache was evaluated by visual analogue scale (VAS), and the clinical therapeutic effects in the two groups were observed.Results There were no statistical significant differences in MAP (mmHg, 1 mmHg = 0.133 kPa) between the two groups before treatment and at 2 hours, on 1, 3, 7 days after treatment (control group: 99.7±9.5, 94.2±9.1, 88.6±7.6, 81.8±9.3, 75.6±5.3 respectively, the observation group: 95.4±13.5, 91.2±8.1. 88.9±8.7, 83.2±8.6, 77.2±4.8 respectively, allP > 0.05). Compared with the control group, after treatment for 1, 3, 7 days, the nature of acute headache (dull pain, distending pain) was relieved more significantly, the number of patients with whole head headache was decreased more obviously in observation group [dull pain (cases): 16, 8, 3 vs. 28, 24, 18, distending pain (cases): 11, 6, 2 vs. 22, 16, 10, whole head pain (cases): 12, 5, 3 vs. 26, 20, 16, allP < 0.05]. With the prolongation of treatment, the VAS scores in the two groups were gradually decreased, on 7 days after treatment they reached to the lowest levels, and the degree of descent in the observation group was more significant than that in the control group (0.5±0.4 vs. 1.4±0.9,P < 0.05); thelevels of serum BNDF in the two groups were gradually increased after the 1st day of treatment, reached to the highest level on 7 days after treatment,and the degree of increase in observation group was more obvious than that in the control group (ng/L: 24.8±2.3 vs. 17.8±2.2). The therapeutic effective rate of the observation group was significantly higher than that of the control group [70.8% (68/96) vs. 53.3% (48/90),P < 0.05].Conclusion The combination of benzene sulfonic amlodipine and Yangxueqingnao granules can effectively relieve the acute headache in HU patients, and its mechanism is related to the increase in expression of BDNF.

To analyze the structural characteristics of the Rap2B gene from Clonorchis sinensis by bioinformatics and to clone and express this gene through genetic engineering methods in order to obtain the corresponding recombinant protein.The structural and functional characteristics of the Rap2B protein were analyzed by using the related bioinformatic softwares. Using the full-length cDNA plasmid clone (Noc009e03) as template , the coding region of Rap2B gene sequence was amplified with PCR and cloned into the prokaryotic expression vector pET-28a(+) and then expressed in E.coli BL21 through IPIG induction. The recombinant protein expressed was purified by Ni-IDA affinity chromatography and detected by SDS-PAGE and Western blotting. It was demonstrated that the size of this gene was 847 bp in length, encoding 141 amino acids and its theoretical molecular weight was 15851.1 daltons. As demonstrated by PCR, double enzyme digestion and DNA sequencing, the recombinant expression plasmid pET-28a(+)-Rap2B was successively constructed and the Rap2B-like gene was highly expressed in E.coli BL21. The recombinant protein was obtained through purification with His affinity chromatography and could react specifically with the serum of rats infected with C.sinensis. Through these investigations, the Rap2B protein may be predicted as a member of the Ras oncogene family protein and is potential in the carcinogenic process of C.sinensis.

Objective To observe the long-term toxicity of Jiuxin Fumai Injection and to investigate the safety of clinical medication.Methods The rats were given intramuscular injection with Jiuxin Fumai Injection in large,medium,small dosage(respectively 20,10,5g? kg-1)every day for two weeks,and normal saline group served as the normal control.Two weeks after drug withdrawal,the toxic reaction in rats was observed.Results After two-week continuous administration,all the animals were alive.Some animals were vomiting and getting excited when administered the large dosage and medium dosage injection.The blood sugar elevated,the thoracic gland coefficient lowered,the hepatic cells were cloudily swollen in the animals of large dosage group.Two weeks after drug withdrawal,the above phenomenon vanished.There was no obvious toxic reaction in the small-dosage injection group.Conclusion Long-term administration of Jiuxin Fumai Injection in large dosage shows certain toxic reaction in rats.The safe dosage for intramuscular administration is less than 5 g? kg-1? d-1.

Selection and affinities of Cd binding peptides were assayed by phage random dodecapeptide library and affinity chromatography. Two Cd binding peptides were obtained, it was found that the affinities of Cu~ 2+ ,Co~ 2+ ,Zn~ 2+ ,Ni~ 2+ for Cd binding peptides were higher than that of Cd~ 2+ and Cr~ 2+ after detection of the amplified Cd binding peptides displayed phages to different heavy metal-charged resins; the detoxification of E.coli to Ni~ 2+ and Cd~ 2+ was enhanced when infected by Cd binding peptide displayed phages as compared with those of the control. The interaction of Cd binding peptide displayed phages with heavy metals charged resins was also observed under microscope. The work would be of great value and consequences for the study of interaction between heavy metals and proteins(peptides), as well as thedetoxification and bioremediation of heavy metals.

This study was aimed to explore the change of single nucleotide polymorphism (SNP) of thrombin-activatable fibrinolysis inhibitor (TAFI) and its correlation of 2 sites (505a/g, 1040c/t) in its gene-coding region with venous thromboembolism (VTE). The genotype distribution of TAFI in 80 patients with VTE and 80 normal controls was detected by allele-specific PCR. The results showed that the distribution of each genotype of 505a/g polymorphism was not significantly different between the VTE and control groups (P > 0.05). However, t allele frequency of 1040c/t in VTE group decreased significantly as compared with the control group (40% vs 53.75%, P < 0.05), mainly due to the decrease of the proportion of tt homozygous in VTE group. It is concluded that obvious relationship is found between the polymorphism of 1040c/t in TAFI gene and VTE patients. t allele genotype may paly a protective role in VTE. The polymorphism of TAFI 505a/g may be not associated with VTE.

Objective To study the correlations of VDR FokⅠgene polymorphism with type 2 diabetes in postmenopausal women of Han nationality in south Sichuan. Methods 160 patients with type 2 diabetes (T2DM) and 190 healthy cases were enrolled in the study. The VDR FokⅠgene polymorphisms were detected using RFLP-PCR and DNA sequencing. Results The FF, Ff and ff genotype frequencies were 32.5%, 47.5%and 20% in the T2DM group and 15.8%, 53.7%, 30.5% in the control group, respectively (P < 0.05). The allele frequencies were 56.3%, 43.8% in the T2DM group and 42.6%, 57.4% in the control group, respectively (P < 0.05). The risk of T2DM in the FF genotype people was 2.568 times higher than Ff/ff genotype (adjusted OR = 2.568, 95%CI = 1.246 ~ 5.292, P < 0.05). The levels of 2 h PG and HbA1C in the FF genotype people were significantly higher than those of the Ff/ff genotype people (P<0.05). Conclusions There was an association between the VDR FokⅠgene polymorphism and type 2 diabetes incidence in the postmenopausal women in south Sichuan area.
