Objective To explore the expression of chemerin and chemerin receptor ( chemokine-like receptor 1, CMKLR1) during different periods of non-alcoholic fatty liver disease ( NAFLD) rat model induced by methionine- and choline-deficient ( MCD) diet. Methods Thirty-six Wistar rats were divided into control group and MCD group in random. After one week quarantine and acclimation period, these two groups were fed either normal chow or MCD diet. The animals were respectively sacrificed at the first week, the forth week, and the tenth week. The levels of alanine transaminase (ALT), blood lipid profile, liver function, and the content of triglyceride in liver were detected. HE staining was done to observe the morphologic change of liver. The mRNA expression changes of chemerin and CMKLR1 in liver were measured using real-time PCR, and the change in chemerin mRNA level was further confirmed in liver by Northern blot. Finally, the concentration of chemerin in serum was measured by Western blot. Results The mRNA level of chemerin decreased significantly after four and ten weeks MCD feeding, although no obvious changes were found at first week, similar changes were found in serum chemerin (1.00±0.11 vs 0.96±0.39; 1.00±0.12 vs 0.21 ±0.77; 1.00±0.42 vs 0.21 ±0. 11). Contrasting with the change of chemerin(1.00±0.08 vs 0.72±0.10;1.00±0.24 vs 0.63±0. 31 ;1.00±0.05 vs 0.50±0.13), the mRNA level of CMKLR1 increased after MCD feeding( 1.00±0. 14 vs 0. 84±0. 26; 1.00±0. 38 vs 1. 51 ±0. 33; 1. 01 ±0. 13 vs 1. 84 ± 0. 39 ). Conclusion The change of chemerin and its receptor may participate in the process of the nonalcoholic fatty liver disease.

PCR method was used to introduce the code sequence of Factor Xa cleavage site to the 5′ end of cecropin CMIV mutant gene X, then the gene was cloned into the expression vector pGEX-KG, and was highly expressed in E. coli BL21 by IPTG induction. The fusion protein was purified by affinity-chromatography and was cleaved by Factor Xa. Cecropin X with antibacterial activity was obtained after purified by ion-exchange chromatography.

Objective To systematically review the efficacy of cinepazide maleate injection in the treatment of the acute Cerebral Ischemic Stroke.Methods We searched the PubMed,EmBase,Cochrane Central Register of Controlled Trials,Clinical Trials,CNKI,Wanfang Database,VIP and Chinese Bio-Medicine Database from established to Sept.2016.We used RevMan 5.3 software to perform Meta-analysis of National Institute of Health Stroke Scale (NIHSS) score improvement and response rate.The intervention measures of the treatment group were cinepazide maleate injection with basic treatment while which of the control group are basic treatment with placebo,with western medicine injections or with traditional Chinese medicine injections.Results Twenty randomized controlled trials involving 2237 patients were included.The results of meta-analyses:The NIHSS score of treatment group decreased 2.73 more than the control group.The response rate of the treatment group was 1.22 times higher than that of control group.The differences were statistically significant (all P ＜0.01).Conclusion Cinepazide maleate injection has good efficacy which could decrease the NIHSS score and response rate.

Objective To determine the changes of cerebrospinal fluid(CSF) ?-endorphin(?-EP) and C-reactive protein(CRP) in children with central nervous system(CNS) infection.Methods Sixty-five children suffered from CNS infection were determined the plasma and CSF ?-EP and CRP concentration during the acute and recovering stage with radioimmunoassay, which included 48 viral encephalitis, 12 purulent meningitis and 5 tuberculou meningitis,and 24 non-CNS disease children were as control group.Results The concentrations of plasma and CSF ?-EP of every experimental group were obviously higher than those of control group during the early stage of CNS infection and these were obviously lower during the recovering stage. The serum concentration of CRP during acute stage was significantly higher than that during recovering stage. No change of serum and CSF CRP concentration was determined during either the acute or recovering stage in the other two experimental groups.Conclusions Determining the plasma and CSF ?-EP is mea-(ningful) in early diagnosis of CNS infection,and determining the serum CRP at the same time may be helpful in differentiating septic and inseptic infection.

OBJECTIVETo study the genotype of swines isolated from humans and their relationships with hepatitis E virus (HEV) in the rural areas of southern China.

METHODSSpecimens collected from normal people with HEV-IgM positive, acute hepatitis E patients and from swine in the same area were detected for HEV RNA using RT-nPCR with ORF2 primers. The positive PCR products were cloned and sequenced.

RESULTS13 out of the 132 samples from swine stool, 4 of 26 HEV-IgM positive sera of normal people and 1 of 4 acute hepatitis E patients' stool sample and sera were tested positive for HEV RNA. Data from sequence analysis showed that the identity at nucleotide level was 89.3%-100.0% among the 10 isolates which shared 78.7% - 84.7%, 83.3% - 85.3%, 76.0% - 80.0% and 84.7% - 95.3% nucleotide sequence identity with HEV genotype I, II, III and IV respectively in the region (nt6317- 6466).

OBJECTIVETo compare differences of angiogenesis among collagen- chitosan, collagen-sulfonated carboxymethyl chitosan porous scaffolds and acellular dermal matrix after these three different scaffolds with silicone membrane were transplanted on the wounds of full thickness burn, and the wound repair of different scaffolds with epidermis grafting on.

METHODSAngiogenesis in different dermal scaffolds, the wound surface and epidermis survival were observed in 1, 2, and 3 weeks after the three different scaffolds were respectively transplanted on wounds of full thickness burn with debridement in 6 Bama miniature pigs (total 18 pigs in 3 groups). At the same time, CD34 positive signals (neo-forming microvessels) were detected by immunohistochemical staining. The wounds without any scaffold transplantation were studied as the control.

RESULTSAngiogenesis had been fundamentally finished in 2 weeks after implantation of collagen- sulfonated carboxymethyl chitosan porous scaffold. And fundamental angiogenesis in collagen- chitosan porous scaffolds and acellular dermal matrix needed at least 3 weeks. Neo-forming micro-vessels perpendicular to wound beds with these three different scaffolds were more than those in the control wounds without scaffold. CD34 positive signals (neo-forming micro-vessels) were significantly higher in wounds at the second week than those in wounds at the first week. And those in wounds at the third week were significantly higher than those in wounds at the second week in all wounds with different scaffold transplantations and the control wounds. CD34 positive signals in the group of sulfonated carboxymethyl chitosan porous scaffold on the 1st, 2nd and 3rd week after the scaffold transplantation were significantly higher than those corresponding signals in the other three groups. Epidermis on the sulfonated carboxymethyl chitosan porous scaffold which had been transplanted on burn wound for 1 week could survive perfectly, however, epidermis on the collagen- chitosan porous scaffold or acellular dermal matrix could not survive until these two scaffolds had been transplanted on the burn wounds for at least 2 weeks.

CONCLUSIONSThese three different scaffolds could repair the full thickness skin defects caused by burn, and angiogenesis of sulfonated carboxymethyl chitosan porous scaffold is the best.
