Journal of Applied Clinical Pediatrics 1992;0(06):-
Objective To study the influence of interleukin-11 (IL-11) on graft versus host disease(GVHD) and graft versus leukemia(GVL) after allogenic bone marrow transplantation and related mechanism in acute lymphoblastic leukemic(ALL) junior mice.Methods The impact of IL-11 on CD4 and CD8 T cell after transplantation was evaluated by flow cytometry;it was observed that the GVHD pathology chance of internal after transplatation in ALL junior mice;the survial time after transplantantion was recorded;the level of tumor necrosis factor-?(TNF-?) which evidently related to GVHD was evaluated by ELISA.Results IL-11 could decrease the quantity of CD4 T cell and increase CD8 T cell;IL-11 could obviously increase the survival time and decrease the level of TNF-?. After ALL junior mice transplatated,IL-11 could delay and relieve GVHD.Conclusion IL-11 can alleviate GVHD and retain the effect of GVL after allogenic bone marrow transplantation.

The brown slime inside pipeline of the polluted mineral waters well was analyzed. It was confirmed that the brown slime was a biofilm formed mainly by growth of bacteria contaminant, using microscope analysis. After treated with HCl, the brown crystals and mycelioid matter presented in slimes disappeared. It was verified these were metal deposits. The samples produced Prussia blue deposits by dropping K 4Fe(CN) 6 and HCl, which proved that the metal deposits were iron compound. Also it was believed the biofilm was produced by growth of iron bacteria, mixed with deposits of iron compound. The iron bacteria have been isolated from the slimes and cultured in the laboratory. The colony on agar plate also produced Prussia blue deposits after treated with K 4Fe(CN) 6 and HCl. The cells form of pure culture was the same as that in the samples by electronmicroscope analysis. Therefore, It indicated that the bacteria on biofilm inside pipeline were iron bacteria mainly.

To analysis the differences between Tripterygium wilfordii and T. hypoglaucum, specimens of their leaves were collected from five production regions and analyzed by ultra performance liquid chromatography coupled with quadrupole time of flight mass spectrometry (UPLC-Q-TOF-MS). The data were analyzed by multivariate statistical method, such as hierarchical cluster analysis (HCA) principal component analysis (PCA) and orthogonal signal correction partial least square discrimination (OPLS-DA). Potential markers with VIP values above 5.0 and corresponding r values above 0.85, were selected and further tested by combining mann-Whitney nonparametric. Those with P < 0.001 and AUC = 1 were confirmed as metabolite markers to discriminate them from each other. Results revealed that the two species were obviously different in their leaf metabolites. Based on their mass spectra, 23 potential metabolite markers were identified to distinguish T. wilfordii from T. hypoglaucum.

ObjectiveTo investigate the epidemic situation of brucellosis in Datong city, and to provide scientific evidence for making appropriate prevention and control measures. MethodsSurveillance data of human brucellosis in 7 countris and 4 districts in Datong city between 2006 and 2009 were collected, throng the national network straight quote system in an infectious diseases. Excel database was established and all data were statistically analyzed. Incidence of brucellosis in local population was analyzed. The regional distribution, time distribution,occupation, age and sex distribution were analyzed. Epidemic characteristics and trend of brucellosis in Datong city were summarized. Results A total of 5195 cases of brucellosis patients in Datong were found between 2006 and 2009, the average incidence rate was 57.51/10 million. All counties had the disease, and the onset of the disease mainly in the spring and summer. Most cases were young males. Farmer case was 81.67%(4243/5195) of the total patients. ConclusionsFrom 2006 to 2009, epidemic characteristic of Datong human brucellosis ishigh-low-high(incidence). We suggests the Department concerned to strengthen the prevention and control of the disease in some counties, focusing on spreading of disease prevention and control knowledge among farmers and increase their self-protection awareness.

To observe the clinical results of innercapsular phacoemulsification with primary intraocular lens ( lOL ) implantation in the treatment of lens dislocation.METHODS: A total of 23 cases ( 23 eyes ) of lens dislocation ( lla and llb ) were underwent innercapsular phacoemulsification combined with primary lOL implantation. lOL implantation were underwent during operation, the complications of intraoperative and postoperative, postoperative vision, intraocular pressure ( lOP ) , corneal endothelial cell, lOL location were analyzed.RESULTS: The operations were successfully completed for all patients in accordance with the pre - surgery program; lens nucleus or its fragments did not crash into the vitreous cavity; 20 cases of corneal edema and 17 cases of lOP presented at the first day after surgery, the deviation or displacement of lOL and serious complications such as retinal detachment were not appeared. At the first week postoperation, the average lOP was 15. 81 ± 2. 10mmHg, with statistically significant differences when compared with the preoperative ( P<0. 01 ) , the visual acuity in all eases increased, with statistically significant differences when compared with the preoperative ( P < 0. 01 ). Corneal endothelial cell density and percentage of hexagonal cells decreased, the variation coefficient increased in first week of postoperative, with no statistically significant differences when compared with the preoperative (P>0. 05) CONCLUSlON: lnnercapsular phacoemulsification combined with primary lOL implantation in the treatment of the whole lens dislocation (‖a and ‖b ) can restore function in patients with diplopia and control lOP effectively, reduce corneal endothelial cell damage, which is an effective method to treat the whole traumatic lens dislocation.
