It has been shown that powerful Saussurea involucrata spirit has effects of expelling wind and removing dampness, anti-inflammation and alleviating pain, and activating blood flow and diminishing swelling. The pharmacokinetic findings show that this drug has advantages of slow-absorption, long-action and high-bioavailability.

Objective To screen the HBV SPⅡ promoter DNA-binding protein, and to investigate its potential role in the regulation of replication and expression of HBV DNA. Methods By using HBV SPⅡ biotinylated promoter DNA as a selective molecule, the T7 select human liver cDNA library was biopanned and the positive clones were selected. After screening, amplification of positive plaques was performed for inserted DNA fragment and then they were cloned into the pGEM-Teasy vector. Results Four positive plaques were chosen for DNA sequencing. The binding protein of HBV SPⅡ promoter was demonstrated as nicotinamide adenine dinucleotide (NADH) dehydrogenase 4 by BLAST. Conclusion The result suggests that this approach may provide a new tool for the study of replication and expression mechanism of HBV DNA.

Objective To investigate the association between TLR4,C-Jun N-terminal kinase,tumor necrosis factor-α(TNF-α),Leptin changes and chronic intermittent hypoxia(CIH). Methods Twenty-four SD rats were divided into 3 groups (n=8):control group,CIH 6 weeks group, CIH 8 weeks group. After the modeling,the change of blood pressure and renal artery were observed by the use of non-invasive blood pressure analyzer and HE staining. ELISA was employed to determine the production of TNF-αand Leptin in sera of these animals. The expressions of TLR4 and JNK mRNA were detected by real time quantitativer everse transcription-polymerase chain reaction ( QRT-PCR) method in the adipose tissue. Results The blood pressure in intermittent hypoxia group was signifi-cantly higher than those in control group(P<0.01), and the renal artery pathological changes in intermittent hy-poxia group were significantly heavier than those in control group;the content of TNF-α and Leptin in intermittent hypoxia was significantly higher than those in control group(P<0.01),and the content of TNF-α and Leptin was significantly increased with the days of hypoxia;the expression of TLR4 and JNK at mRNA levels in intermittent hy-poxia was significantly higher than those in control group(P<0.01),and the expression of TLR4 and JNK at mR-NA levels was significantly increased with the days of hypoxia. Conclusion TLR4,JNK,TNF-α,Leptin may be in-volved in the inflammatory response of chronic intermittent hypoxia in rats.

Objective To study the effect of the extract of total flavonoids of Chrysanthemum indicum(TFC) on adjuvant arthritis(AA) synoviocytes.Methods Totally 0.1ml of the complete Freund's adjuvant was subcutaneously injected into the right hind feet pads of 20 SD rats.24 days after immunity synoviocytes in the knee joint were treated with TFC.Cell morphology was examined with electron microscopy.Protein level of caspase-3 cleaved fragments was analyzed by Western blotting.The annexin V stain assay was applied to explore the effect of caspase-3 inhibitor on the amelioration in synovial cells apoptosis of AA rats.Results Typical morphology and biochemical feature of apoptosis in synovial cells of AA rats were observed with TFC.The protein level of caspase-3 cleaved fragments increased obviously and was related with the concentration of TFC in synovial cells of AA rats.The apoptotic cells positively stained with annexin V were markedly reduced by caspase-3 inhibitor.Conclusion TFC can induce apoptosis in AA rats synoviocytes,which may achieve therapeutical effects in AA.The activation of caspase-3 may be one of the main causations.

Brain injury is one of the most serious diseases in neonatal period,which can cause cerebral palsy,motor development delay,cognitive dysfunction and learning difficulties and other sequelae,and severely affects the health development and quality of life of the newborn.Neonatal brain injury (NBI) is a wide range of diseases caused by a variety of causes,its clinical manifestations lack specificity,clinically,it is difficult to judge the severity,duration and the time of prenatal injury,and it has been paid much attention to by scientific researchers and clinicians.At present,imaging method is a major means of NBI diagnosis,but imaging examination is usually a lag and limitations.Levels of humoral biomarkers change early after brain injury,and early brain injury can be predicted by detecting their changes.In recent years,a variety of sensitive brain damage biomarkers have been detected in various body fluids of newborns,mainly including neuron-specific enolase (NSE),ubiquitin carboxyl hydrolase L1 (UCH L1),S100B protein,tau protein,myelin basic protein (MBP),glial fibrillary acidic protein (GFAP) and activin A and so on.the application and research progress of these commonly used biomarkers in NBI are reviewed in this paper.

OBJECTIVETo explore the therapeutic effect of diagnosis and treatment program of integrative medicine (IM) on level 2 hypertension in the young and middle-aged patients and their ambulatory blood pressure.

METHODSA randomized, placebo parallel and controlled, multi-center clinical trial was performed. Totally 199 young and middle-aged level 2 hypertension patients were randomly assigned to the treatment group (99 cases) and the control group (100 cases). All received combined hypotensive treatment program by taking Nifedipine Sustained Release Tablet and Hydrochlorothiazide as basic drugs. Patients in the treatment group additionally took Western medicine (WM) combined Jiangyabao serial drugs (0.31 g per tablet, 2 tablets each time, twice daily), while those in the control group additionally took WM combined simulative agents of Jiangyabao serial drugs (0.31 g per tablet, 2 tablets each time, twice daily). The treatment course was 8 weeks for all, and 24-week follow-ups performed. 24 h ambulatory blood pressure and casual blood pressure, and their efficacies were compared between the two groups, and safety assessed as well.

RESULTSCompared with before treatment in the same group, daytime and night casual blood pressure, as well as 24 h ambulatory blood pressure were all obviously improved in the two groups (P < 0.01). Average diastolic and systolic blood pressures at night decreased more in the treatment group than in the control group with statistical difference (P < 0.05). There was no statistical difference in total efficacies of daytime casual blood pressure or ambulatory blood pressure (P > 0.05).

CONCLUSIONJiangyabao serial drugs combined WM in treating young and middle-aged level 2 hypertension patients showed obvious effect in improving night blood pressure, especially for night diastolic blood pressure.

Aim To study the transport of geniposide and geniposide in Zhizi Bopi Decoction in MDCK cell membrane model. Methods The safety concentration of geniposide and Zhizi Bopi Decoction in MDCK cells were determined by MTT assay. Then the MDCK cell membrane model was used to investigate the transport of drugs. Firstly, the effects of time, drug concentra-tion, P-gp inhibitor and EDTA on the absorption and transport of geniposide were studied systematically. Secondly, the differences were compared between the transport of the same concentration of geniposide as single compound and that in Zhizi Bopi Decoction in MDCK cell model. The drug concentration was deter-mined by high performance liquid chromatography ( HPLC) to calculate the apparent permeability coeffi-cient (Papp). Results Geniposide transport in MDCK cell monolayer was time and concentration dependent. P-gp inhibitors had no significant effect on its transport and the transport of geniposide was enhanced by ED-TA. The absorption Papp of different concentrations of geniposide in Zhizi Bopi Decoction were ( 8. 96 ± 0. 35 ) × 10 -7 cm · s-1 , ( 8. 95 ± 0. 38 ) × 10 -7 cm · s-1 and (9. 16 ± 0. 30) × 10 -7 cm·s-1, significantly higher than the absorption Papp of geniposide as single compound(5. 85 ± 0. 44) × 10 -7 cm·s-1, (6. 88 ± 0. 38) × 10 -7 cm·s-1 and (6. 31 ± 0. 19) × 10 -7 cm ·s-1 ( P<0. 05 ) . Conclusion The transport of ge-niposide in MDCK cell membrane model is passive transport and is not affected by P-gp. Geniposide may transport via the paracellular route. The Zhizi Bopi De-coction can increase the absorption of geniposide.
