The cytokines have close relationship with the rejection and infection in organ transplantation.The cytokine gene polymorphism influences the secretion of cytokines.The relationship between the rejection and infection in organ transplantation and some cytokines gene polymorphism is reviewed in this article.

Objective To determine the morphology, bacteria and endotoxin content of bio-films on the inner surface of PVC tubes in hemodialysis water treatment system. Methods We dissolved biofilms of segments before and after reverse osmosis machine for bacterial count and identification. We studied biofilm structure of segments before and after reverse osmosis machine with eyes and scanning electron microscope. Biofilms of all 7 segments were dissolved for qualitative and quantitative assay of endotoxin. Results The inner surface of segment before reverse osmosis machine was homogeneously distributed with activated carbon powder deposition. The segment after reverse osmosis machine was normal. With scanning electron microscope, biofilm with successive surface and sandwich was found on the inner surface of segment before reverse osmosis machine, formed by clustering bacillus, activated carbon powder and some coccus. Bacteria of the same shape and length were found on segment after reverse osmosis machine, but fewer and looser. Bacterial culture and identification showed the former was mostly gram-negative bacillus, the latter was only a few micrococcus. Endotox-in of biofilm was between 2. 0 EU/mL and 4. 0 EU/mL. Quantitative assay showed: segment after softener (2.821 ±0. 807) EU/mL; segment after active charcoal canister(3. 635 ±0. 427) EU/ mL; segment before reverse osmosis machine (3.687 ±0.271) EU/mL; segment after reverse osmosis machine (2. 041 ±0. 295) EU/mL; exit of power pump (1. 983 ±0. 390) EU/mL; the 1st dead space (2. 373 ± 0. 535) EU/mL; and the 2nd dead space (2. 858 ± 0. 690) EU/mL. Conclusion Biofilms are found on the inner surface of segment before and after reverse osmosis machine . Endotoxin level from high to low is as follows: segment before reverse osmosis machine, segment after active charcoal canister, the 2 nd dead space, segment after softener, the 1 st dead space, segment after reverse osmosis machine, exit of power pump. The character of the bacteria and endotoxin of the biofilm can help us find better ways to control them.

A new vest pocket medical instrument is here presented. It can automatically detect and identify the signals of the onset of epileptic seizures, and then as necessasy, will automatically generate an acoustic stimulation that may weaken and shorten the epileptic activity at the initial stage.

A colistin producing strain Paenibacillus polymyxa AS1.541 was treated by N-methyl-N-nitro-N-nitrosoguanidine(NTG) for increasing yields of the antibiotic colistin.High-yield strains were obtained by selection of deregulated mutant which grow on media containing colistin,a self second metabolite,and ethionine,an analogue of methionine.Some of these mutants have higher yield of colistin than that of the parent strain.

AIM: To analyze the effect factors of trabeculectomy combined with intraoperative application of mitomycin C in the treatment of neovascular glaucoma.
METHODS: Fifty patients (50 eyes) with neovascular glaucoma collected from January 2013 to August 2015 in our hospital were treated by trabeculectomy combined with intraoperative application of mitomycin C. Single factor and multi factor variables analysis were used for effect factors of trabeculectomy combined with intraoperative application of mitomycin C in the treatment of neovascular glaucoma.
RESULTS: By results of single factor variable analysis,< 50 years old, preoperative intraocular pressure ( IOP) was ≥45mmHg and postoperative occurrence of anterior chamber hemorrhage were risk factors for treatment failure ( P < 0. 05 ), and gender, proliferative diabetic retinopathy and previous cataract surgery and prior photocoagulation were not the risk factors for failure (P>0. 05 ). By multivariate analysis, < 50 years old and postoperative occurrence of anterior chamber hemorrhage were risk factors for treatment failure ( P < 0. 05 ), and preoperative IOP≥45mmHg was not a risk factor (P>0.05). CONCLUSION: For patients < 50 years old with neovascular glaucoma, should be careful on the selection of surgical treatment. For high- risk patients, we should strengthen the monitoring and give timely intervention, which are helpful to improve the prognosis.

Objective To analyze nucleic acid sequence homology of the 6 kb(pYC) plasmid of Yersina. pestis (Y. pestis) isolated from Yurman by searching GenBank. Method The search of sequence similarity was accomplished with BLAST. Results The pYC plasmid sequence had high homology with some genes in nueleotide sequence, such as: 97.1% homology with Shigella sonnei pKYM, 92.1% homology with Haemophilus influenzae(H. influenzae) gene, Salmonella typhi (S. typhi) gene LT2 and plMVSI with 88.2% and 87.2% of homology respectively, Escherichia coli(E, coli) O157:H7 and K-12, ECOR31 with 81.4%, 81.4% and 84.7% of homology respectively. This plasmid ORFs could code for some proteins which were similar with others in GenBank, such as: ORFi and H. paragallinarum replication protein B(47.2%), ORF4 and E. coli hypothetical protein(52.7%), ORF5 and Y. pseudotuberculosis Tile (48.3%), ORF6 and E. coil Pilx5/VirB5-1ike protein (42.3%), Y. enterocolitica TriD protein(38.5%), ORFIO and S. typhimurium LT2, E. coli O157:H7 hypothetical protein(83.1% and 81.9%, respectively), ORF11 and E. coli, damage-inducible protein J(81.4%). Conclusions The pYC plasmid sequence has high homology with a few bacterial genes of Enterobacteriaceac. This plasmid may code for some proteins that are similar with hypothetical protein, damnge-indncible protein, TriD and TilE protein, Pilx5/VirB5-hke protein of Escherichia or Yersinia.

OBJECTIVETo explore an ideal method for repairing the skin-soft tissue defects according to the different anatomical units of cheek, and find reasonable design principles to transfer the expanded flaps.

METHODSAccording to the location of the defect, we placed 1-3 appropriate expanders nearby, when the flap expanded enough we adopted advanced skin flaps, rotation-advanced skin flaps or transposition skin flaps to repair the defect. In this group of 269 cases, the defects were secondary to hemangioma, various scars, nevus or nevus excision.

RESULTSIn all 269 cheek defects, 305 expanded flaps were developed which included 145 rotation-advanced flaps, 121 advanced skin flaps and 39 transposition skin flaps. 52 of them generated complications, including blood circulation disorder of the distal part of flaps, hematoma, infection, injection, lower eyelid ectropion, expander extrusion and capsule contracture. Mostly, these complications didn't affect the final results.

CONCLUSIONSThe principles presented in this article are the guidelines to treat the skin-soft tissue defect of check with tissue expansion. The satisfied results come from the reasonable flap designs.

In this article, the research of chemical constituents and bioactivities in recent ten years has been reviewed of plants from the 12 genera in Flacourtiaceae related to the medicinal resources in China. The research in China about the plants from Flacourtiaceae was done very little, but many literatures have been reported abroad. The plants from Flacourtiaceae mostly contain the constituents such as aromatic glucosides, lignanoid glucosides, diterpenoids and cyclopentenoid cyanohydrin glucosides et al. These compounds or plant extracts mainly show antibacterial, antiviral, antitumor, hypolipidemic and hypoglycemic activities. The research of plants from Carrierea, Itoa and Bennettiodendron of Flacourtiaceae in China is still blank. The systemic research about chemical constituents and bioactivities of plants from these genera will play important roles in the discovery of novel natural products and active constituents, and provide valuable reference for the classifying of plants from these genera.
