ABSTRACT
Communesins are a class of alkaloids mainly from the marine-derived fungi belonging to the genus Penicillium. The communesins contain a unique, densely functional caged seven-ring system skeleton, with five stereogenic centers at least, of which two are the vicinal quaternary carbon centers. These structural features make the synthesis of these compounds extremely challenging. In addition, communesins have been known to have a variety of biological activities such as the insecticidal, cell proliferation inhibito ry and significant cytotoxic activities. At present, eight research groups have completed the total synthesis of several communesins, and reports on the skeleton synthesis have been published. This paper summarizes the chemical skeleton synthesis and total synthesis of communesins in a chronological order, so as to provide a reference for further studies on this class of natural compounds.
ABSTRACT
Objective To evaluate the effect of transcranial direct current stimulation (tDCS) on post-stroke dysphagia. Methods Cochrane Library (CENTRAL), Medline, EMBASE, CBMdisc, VIP, CNKI and WANFANG Digital Journals were searched to collect randomized controlled trials (RCTs) about transcranial direct current stimulation for post-stroke dysphagia until February 2018. Two researchers independently screened literature, extracted data and evaluated the quality of the included studies. Then, meta-analysis was performed using RevMan 5.3 software. Results A total of eight RCTs were screened, including 225 patients. Compared to the control group, tDCS was effective on post-stroke dysphagia (SMD=0.71, 95%CI: 0.32~1.10, P<0.001) with safety. Conclusion tDCS could improve swallowing function of post-stroke dysphagia. Due to the limited quantity and quality of the included studies, more high quality studies are needed.
ABSTRACT
Objective To study the difference between multi-drug resistant bacteria in patients with severe bums under air isolation and non-air isolation measures.Methods Sixty severe burn patients were selected and randomly divided into non air isolation group and air separation group by random digits table method with 30 cases each.At 0 days and 14 days in the group,the sputum,the air and the material table in the ward were sampled in the two sets of warp,the multidrug resistant bacteria and the drug resistance were identified.Results At the time of enrollment,31.67％ (19/60) patients were infected with Acinetobacter baumannii and 33.33％ (20/60) with Klebsiella pneumoniae.There was no significant difference between the two groups (P ＞ 0.05).Acinetobacter baumannii and Klebsiella pneumoniae were multidrug-resistant bacteria.The results of group,air,surface and sputum culture had significant influence on the infection of multidrug-resistant bacteria (odds ratio:1.582,1.265,2.314,0.100,95％ confidence interval,P＜ 0.05).At the 14th day,the infection rate of drug-resistant bacteria cultured in sputum was 50.00％ (15/30) in air isolation group and 40.00％ (12/30) in non-air isolation group.The difference between the two groups was statistically significant (x2 =-3.962,P ＜ 0.05).Conclusions Air isolation measures can reduce multidrug-resistant bacteria in the surface and air of the ward,and air isolation measures can reduce the incidence of multidrug resistance in severe burn patients.
ABSTRACT
Tuberculosis(TB),a chronic infectious disease caused by Mycobacterium tuberculosis(MTB), is the outcome of the interaction between polygenes and environmental factors,which has been shown in lots of genetic studies. In recent years,the research of TB susceptibility genes and their single nucleotide polymorphism(SNP)loci has become a hot topic,but genes and SNPs exactly associated with TB susceptibility are rarely reported. What's more,some susceptibility genes are different among races, populations and geographical distributions, resulting in inconsistency, or even contrary conclusions drawn from local studies of different populations or areas. In order to obtain susceptibility genes that are widely applicable and exactly associated with TB,it is necessary to screen the genes preliminarily in the laboratory animals with gene diversity, and thereafter, verify those genes in animals or humans. The Collabrative Cross(CC)mice have the advantages of diverse and clear genetic background,which can provide a new tool for the research of TB susceptibility. This review summarizes the advances in the studies of TB susceptibility genes and their SNPs, and looking forward to the application of CC mice in these studies and its significance.

ABSTRACT
The main objective of this research is to observe protective effects of three phenylallyl compounds(cinnamyl alcohol,cinnamaldehyde and cinnamic acid)from Guizhi decoction against ox-LDL-induced oxidative stress injury on human brain microvascular endothelial cells(HBMEC).In this study,the toxicity and optimal protective concentration of three phenylallyl compounds from Guizhi decoction were determined by MTT assay.The HBMEC were divided into control group(DMSO),model group(ox-LDL),tert-butylhydroquinone (t-BHQ) group,cinnamyl alcohol group, cinnamaldehyde group and cinnamic acid group.The model group were treated with ox-LDL (50 mg•L⁻¹)for 24 h,other groups were separately treated with t-BHQ, cinnamyl alcohol, cinnamaldehyde and cinnamic acid of 20 μmol•L⁻¹, and exposed to ox-LDL (50 mg•L⁻¹) for 24 h at the same time.The survival rate of HBMEC was detected by MTT assay,reactive oxygen species(ROS) production of injured cells were detected using laser scanning confocal microscope (LSCM),the content of SOD, MDA, eNOS and NO in HBMEC was determined by ELISA, and the expressions of Nrf2 mRNA were detected by quantitative Real-time PCR(qRT-PCR).The results shows that oxidative stress injury of HBMEC could be induced by ox-LDL, the three phenylallyl compounds from Guizhi decoction did not affect morphology and viability of normal HBMEC.Compared with model group, the three phenylallyl compounds from Guizhi decoction could improve the above oxidative stress status and up-regulate Nrf2 mRNA expressions in injured HBMEC(P<0.05, P<0.01) .These findings suggested that the three phenylallyl compounds from Guizhi decoction have certain protective effects against ox-LDL-induced oxidative stress injury on HBMEC(cinnamaldehyde> t-BHQ> cinnamic acid>cinnamyl alcohol),the protective mechanism maybe related to regulation of antioxidant enzymes gene expression in HBMEC by Nrf2.

ABSTRACT
Objective To investigate the epidemioiogical pattern of Borna disease virus (BDV) among different canine breeds in Ili, China, and to analyze its potential phylogeny. Methods BDV p24 RNA fragments were detected from peripheral blood mononuclear cells (PBMCs) of canine by modified nested RT-PCR (nRT-PCR). Possible false positives were excluded by determination of both BDV p40 RNA fragments and PMD19 plasmid standards. Analysis were performed on genetic sequence, homologous comparison, amino acid sequence and phylogeny after p24 positive products were validated. Results BDV p24 RNA fragments were found only in Kazakh Tobet (a shepherd dog) in 8 breeds of 150 cases and their overall positive rate was 11.0% (10/91). Compared with the strain of He/80 from horse and that of S6 from sheep in Germany, the homologous similarities of Kazakh Tobet was 99.2% and 95.7%, and that of amino acid as 100% and 89.3%, respectively. The kinship of Kazakh Tobet was close to He/80 and next to S6. Conclusion There was potential natural BDV infection in Kazakh Tobet in Ili, and its endemic strain was concerned with He/ 80 infecting Ili horse and S6 of German Merino sheep introduced into the region from Germany.
ABSTRACT
Objective To investigate the epidemiological pattern of Borna disease virus (BDV)infection in horses and to analyze the phylogenetic tree of derived BDV in Yili, Xinjiang. Methods We established a modified nested RT-PCR (nRT-PCR) to detect BDV p24 segment in peripheral blood mononuclear cells (PBMCs) and brain tissues of 120 horses in Yili, Xinjiang. Positive products were analyzed by sequencing and homology analysis. Results The positive rate of BDV infection was 2.5% in both PMBCs and brain tissues at the same time. The gene sequence revealed in positive PCR samples was more than 93 % ,identical to that of BDV derived from horses in other countries. We also noticed a high degree of identity ( >98 % ) to standard strain He/80 in gene sequence of positive PCR samples. Conclusion Our study found the presence of BDV natural infection in horses in Yili. The endemic BDV had a high degree of identity to standard strain He/80.
ABSTRACT
<p><b>OBJECTIVE</b>To investigate the iodine levels of urine from 1 month old breast-fed infants and the ones of milk and urine from the lactating women, and to observe the effects of different feeding methods (breast-feeding, mixed-feeding, bottle-feeding) on the iodine status of the infants during the weaning period in Beijing.</p><p><b>METHODS</b>From March, 2001 to March, 2002, the iodine levels of urine from 97 breast-fed infants 1 month of age and the ones in milk and urine from lactating women were measured and compared. The infants followed up were divided into 3 groups (breast-fed, mixed and bottle-fed) until 6 months old. Their iodine levels of urine were measured and compared with the ones of 1 month of age.</p><p><b>RESULTS</b>The median value of urine iodine from breast-fed 1 month old infants was 183 micro g/L, suggesting that the infants with breast-fed had good iodine nutritional status. The median value of urine iodine from lactating women was 122 micro g/L, significantly lower than the value of milk iodine, 201 micro g/L (P < 0.001). which suggests that the lactating women were iodine deficient but could provide infants iodine adequately through breast feeding. Compared with 1 month af age, the urine iodine levels of 6 months old infants with breast-feeding increased (P < 0.001), the ones with bottle-feeding decreased significantly (P < 0.001) and the mixed-feeding group did not change (P > 0.05). The differences among 3 groups were significant (P < 0.005), the urine iodine levels of infants of both breast-feeding and mixed-feeding groups were higher than the ones of bottle-feeding. The breast-feeding group was the highest one among three groups.</p><p><b>CONCLUSION</b>The breast-fed infants were nourished with iodine, but the lactating women were iodine deficient. Accompanied the decrease of the amount of breast milk, the iodine levels of infants urine decreased during the weaning period, some bottle-feeding infants were iodine deficient.</p>

Objective To seek an approach to differentiate between tumors from parotid space and from parapharyngeal space on axial CT or MR imaging. Methods Forty-five patients with tumors originated at the parotid or parapharyngeal space were reviewed retrospectively. The diagnosis was confirmed pathologically in all of the cases. The correlation among neoplasms and the posterior belly of digastric muscle and its shifting situation were evaluated on axial CT or MRI scans by two senior radiologists. All of the estimations were compared with the results of operation. Results Twenty-seven tumors from parotid space were located in the superficial side to the posterior belly of digastric muscle and pushed it medially. On the contrary, 18 neoplasms from parapharyngeal space were situated at the profound side to the posterior belly and shifted it laterally. Conclusion Tumors superficial to the posterior belly of digastric muscle and pushing it medially indicate that they come from parotid space. While neoplasms profound to the posterior belly of digastric muscle and shifting it laterally mean that they come from parapharyngeal space.
ABSTRACT
Objective: To investigate the effect of vitamin B12 on the growth and hemopoiesis of broilers. Methods: The Arbor Acres broilers were fed the experimental diets with different doses of vitamin B12 0.00, 0.008, 0.016, 0.024 mg/kg for 3 weeks. The body weight gain and hematologic indices of the broilers were measured. Results: Vitamin B12 deficiency in the diet could depress the body weight gain and feed conversion ratio of the broilers, decrease the amount of red blood cell and hemoglobin, enlarge the volume of red blood cell, increase the content of each cell hemoglobin, reduce platelet in blood. While 0.008 mg/kg vitamin B12 was added in the experimental diets, the body weight gain and feed conversion ratio of the broilers increased markedly. Furthermore, when 0.016mg/kg vitamin B12 was added to the diet, the number of the red blood cell and the content of hemoglobin of the broilers increased significantly, and the shape and volume of the red blood cell became ordinary. There were significants interrelations between BWG,RBC,Hb,PCV,PLT,MCV,MCH of the broilers and the addition of vitamin B12 in the diet. Conclusion: Vitamin B12 deficiency could result in the megaloblastic animia. 0.02-0.03 mg vitamin B12 per kilo diet was required to maintain the growth and normal hemopoiesis of the broilers.
