To observe the clinical efficacy and safety of bicyclol and polyene phosphatidylcholine in the treatment of liver injury induced by hyperthyroidism. Methods: Totally 112 cases of hyperthyroidism patients were randomly divided into two groups, and both groups were treated with antithyroid drug methimazole. The 56 patients in the treatment group were orally treated with bicyclol, and the other 56 patients in the control group received polyene phosphatidylcholine capsules orally. The changes of liver func-tion were compared before and after the 4-week treatment, including the level of alanine aminotransferase (ALT), aspartate amin-otransferase ( AST) , total bilirubin ( TBIL) and alkaline phosphatase ( ALP) . The efficacy and adverse reactions were also observed. Results:There was no difference in the levels of ALT, AST, TBIL and ALP in both groups before the treatment (P>0. 05), while the levels were all decreased significantly in both groups after the treatment (P<0. 05). Compared with those of the control group, ALT and AST levels of the treatment group were decreased significantly after the treatment (P<0. 05), and the total effective rate of the treatment group was higher than that of the control group with statistical significance (P <0.05), while no statistically significant difference was shown in the levels of TBIL and ALP (P>0. 05). No drug-related adverse events were shown during the treatment. Conclusion:Bicyclol is effective and reliable in the treatment of liver injury induced by hyperthyroidism, and the clinical efficacy is remarkable when compared with that of polyene phosphatidylcholine.

AIM:To investigate the role of p38 MAPK/ATF-2 pathway in C-relative protein ( CRP)-induced endothelial cell activation.METHODS:Human coronary artery endothelial cells ( HCAEC) were cultured and were used between passages 3 and 7.CRP served as a stimulus for endothelial cell activation.Western blotting was performed to de-termine the expression and phosphorylation of eNOS, p38 and ATF2.ELISA was carried out to detect the levels of ICAM-1, VCAM-1 and MCP-1 released from HCAEC.Pharmacological p38 inhibitors SB203580 and SB202190 were used to de-termine the effect of p38/ATF-2 pathway.RESULTS:CRP reduced the p-eNOS level in a concentration-dependent man-ner and induced the release of ICAM-1, VCAM-1 and MCP-1.The p38/ATF-2 pathway was activated by CRP treatment. SB203580 and SB202190 partially rescued p-eNOS level and suppressed the secretion of ICAM-1, VCAM-1 and MCP-1. CONCLUSION:p38MAPK/ATF-2 pathway participates in CRP-induced endothelial activation.

Objective To observe the effects of body weight support training on walking ability of children with cerebral palsy. Methods 40 cases were divided into observation group (n=20) and control group (n=20). All the children accepted rehabilitation therapy based on Bobath approach and biofeedback, while those of observation group accepted body weight support training in addition, for 2 months. They were assessed with Gross Motor Function Measure (GMFM) D and E dimension before and after treatment. Results Both the scores of D and E dimension significantly improved in both groups after treatment (P<0.05), and improved more in the observation group than in the control group (P<0.05). Conclusion Body weight support training can further improve the walking ability in children with cerebral palsy.

This study was aimed to establish an HPLC method to simultaneous determine 6 kinds of monoester and diester aconitum alkaloids. The content of alkaloids in aconite roots, black and white prepared lateral root of aconite and the compatibility of aconite roots with rhubarb were determined. This study provided reference for the interpreta-tion of the attenuation of processing and compatibility of medicines from chemical component aspect. The HPLC analysis was performed on a Phenomenex Gemini C18 (4.6 mm í 250 mm, 5 μm) with 40 mmol·L-1 ammonium ac-etate (adjusted to pH 9.8 with ammonia water) and acetonitrile as mobile phase, with a gradient elution at the flow rate of 1.0 mL·min-1 and a detection wavelength of 235 nm. The results showed that 6 alkaloids in aconite roots achieved favorable separation and a good linearity relationship (r > 0.999) over the studied concentration range. The extraction recoveries were ranged from 96.9% to 102.4% for the 6 alkaloids. The content of diester alkaloids de-creased markedly in processed products and the compatibility of aconite roots with rhubarb compared with the raw a-conite roots. It was concluded that this method was stable, reliable, simple and practical. It can be used for the si-multaneous determination of 6 kinds of monoester and diester aconitum alkaloids in aconite roots. This processing and compatibility can significantly reduce the content of alkaloids in aconite roots in order to reduce its toxicity.

Objective To determine the pathogen of a local dengue fever outbreak in Shenzhen city in 2010,and to analyze the molecular characteristics of the epidemic dengue virus strain as well as explore the possible origin.Methods The serum samples collected from the suspect dengue fever cases were detected for IgM, IgG by enzyme-linked immunosorbent assay ( ELISA ),immunochromatography and dengue virus nucleic acid by real-time polymerase chain reaction (PCR).Serum samples from patients with early stage dengue fever were used to isolate virus with C6/36 and BHK-21 cell lines.The type of isolated virus strain was determined by RT-semi-nested-PCR and realtime PCR.E gene of isolated virus strain was amplified by RT-PCR and sequenced.Homology and phylogenetic tree of E gene of Shenzhen dengue virus with the strains isolated from other areas were constructed.Results IgM,IgG and RNA of type 1 dengue virus were detected in serum samples from dengue fever suspected patients.Type 1 dengue virus named DEV1-SZ1029 was successfully isolated from the serum sample.The homology of nucleotide sequence of E gene of SZ1029 strain with standard type 1 dengue virus HAWAII 45,Fj231/04,GD14/97 and GD05/99 were 94.8％,99.6％,97.7％ and 98.5 ％,respectively.The phylogenetic tree indicated that SZ1029 had the greatest similarity with the D1/Malaysia/36000/05 strain,SG(EHI)DED142808 strain and Fj231/04 strain and they lied in the same branch of the phylogenetic tree.The isolated dengue virus type 1 belonged to genetype Ⅰ with GZ/80,Taiwan87,All patients lived in a certain construction site in Shenzhen and had no recent travel history outside the area in one month before infection.Conclusions The virological,serological and molecular features all identify that the local dengue fever outbreak in Shenzhen in 2010 is caused by type 1 dengue virus and SZ1029 strain may be transferred from Southeast Asian region,and there may be a plague focus in Shenzhen.

Aim To explore micro RNAs-integrated pathogenic signaling to control endothelial-mesenchy-mal transition ( EndMT ) in pulmonary hypertension ( PH) by a network bioinformatic approach. Methods Literature-mining method was used to find PH-relat-ed genes and EndMT/EMT-related miRNAs. Bioinfor-matic prediction approach ( DIANA3 , Miranda4 , PicT-ar5 , TargetScan6 , miRDB7 and microT-CDS8 ) was used for miRNA target prediction. Hypergeometric a-nalysis was used to predict miRNAs related to EndMT in PH. The analysis of interactions between PH-rele-vant genes( PH network) was performed with the use of Biological General Repository for Interaction Datasets ( BioGRID ) . These miRNAs were ranked with the highest probability of substantial overlap among their gene targets in the PH-network, the relationship be-tween their targets and the PH functional categories which include hypoxia, inflammation, and transforming growth factor/BMP signaling. Then, the part of results was validated by animal experiment. Lastly the miR-NA-Target network was built using Cytocape 3 . Results List of 230 genes was compiled that were directly im-plicated in the development of PH and 189 miRNAs were related to EndMT in PH. Among 189 miRNAs, only 22 microRNAs(miR-let-7 family, miR-124, miR-130 family, miR-135, miR-144, miR-149, miR-155, miR-16-1, miR-17, miR-181 family, miR-182, miR-200 family, miR-204, miR-205, miR-21, miR-224, miR-27, miR-29 family, miR-301a, miR-31, miR-361 and miR-375) were related to hypoxia, inflamma-tion, and transforming growth factor/BMP signaling. Among these miRNAs, the levels of let-7g, miR-21, miR-124 and miR-130 family were significantly changed in the pulmonary artery in hypoxia-induced PH rats. Conclusions Among numerous miRNAs,22 of which may be involved in hypoxia, inflammation, and transforming growth factor/BMP signaling and re-lated to EndMT in PH by network bioinformatic ap-proach, which provides a theoretical basis for further investigation of EndMT in PH.

A UPLC-MS/MS method based on metabonomic skills was developed to study the serum metabolic changes of rats after acute liver injury induced by CCl4 and to evaluate the action mechanism of Si-Ni-San. The integrated data were exported for principal components analysis (PCA) by using SIMCA-P software, in order to find the potential biomarkers. It showed that clear separation of healthy control group, model group, silymarin group, Si-Ni-San group was achieved by using the PCA method. Nine significantly changed metabolites were identified as potential biomarkers of acute liver injury. Compared with the health control group, the model group rats showed higher levels of phenylalanine, tryptophan and GCDCA together with lower levels of LPC 16 : 0, LPC 18 : 0, LPC 18 : 1, LPC 16 : 1, LPC 20 : 4 and LPC 22 : 6. These changes of serum metabolites suggested that the disorders of amino acid metabolism, lipid metabolism, bile acid biosynthesis and anti-oxidative damage were related to acute liver injury induced by CCl4. Si-Ni-San might have the anti-liver injury effect on all these four metabolic pathways.

OBJECTIVE: To standardize and simplify the drug receving and preparing model. METHODS: Reasonable pharamcy inventory parameters were set up based on our experience; second order drug storeroom dynamic inventory system was designed and applied, and the indexes of drug storeroom inventory and workload of the new and the old models were reported and analyzed. RESULTS: The new warning system provided an optimal inventory, and in which the incidences of overstock or stock shortage, the frequency of daily drug receving, drug kinds and the time used with checking stock and filling receipt were all significantly less than in the traditional model. CONCLUSION: Due to the second order drug storeroom dynamic inventory warning system, the drug receiving was more scientific, the drug stock amount was reduced and the drug receiving time was saved, and the mangament level of hospital drug storeroom inventory was enhanced.

To explore a new method for the therapy of the avascular necrosis of the femoral head, the recombinant plasmid pCD-hVEGF165 was mixed with collagen and was implanted in the necrotic femoral head. The expression of vascular endothelial growth factor (VEGF) was detected by RNA dot hybridization and immunohistochemical method. The repair of the femoral head was observed by histological method. The results showed that the expression of VEGF was detectable in the femoral head treated with VEGF gene. Angiogenesis in these femoral heads was more abundant than the control. Bone repairing was augmented in the femoral head treated with VEGF gene. The results suggest that angiogenesis in bone tissue could be augmented by gene transfection of VEGF and bone repairing would be accelerated accordingly.
