Objective We discussed the application and clinical effect of serf nursing education in patients with infectious tuberculosis. Methods We divided 140 patients with infectious tuberculosis into the test group and the control group with 70 cases in each group. The control group adopted health education. The test group received individual and selective self nursing education, including serf mastering of tuberculosis, self monitoring of illness, completion of ther therapeutic process by oneself, serf management of diet, self regulation andf control of motion and education of self nursing technique. The intervention continued for 3 months. Pulmonary tuberculosis specific knowledge inventory, therapeutic compliance investigation inventory and general questionnaire on living (GQOL) were adopted in the two groups and the results were compared. Results The therapeutic compliance and life quality of the test group were evidently higher than those of the control group after self nursing education (P<0.01). The mastering of tuberculosis knowledge of the test group was also superior than that of the control group (P<0.01). Conclusions Self nursing education could increase the therapeutic compliance as well as the life quality of patients.

Methods Free physical examinations were carried out in population groups of above 30 years old in a certain community in Xinjiang Uygur Autonomous Region and family health files were set up. Totally 108 patients were screened and standardized management was applied in them,besides their conditions before and after the application of the management were investi-gated and analyzed by self-designed "prevention and treatment of hypertension as a chronic disease" and "in-vestigation questionnaire of KAP of patients with hypertension". Results The cognitive rate and rate of con-trol of high blood pressure were more higher after intervention than that before. Conclusions Through a planned health education instruction, popularizing prevention and treatment knowledge of primary hypertension to residents, we can increase the cognitive rate and rate of control of high blood pressure for patients with hyper-tension.

BACKGROUND:Bone marrow mesenchymal stem cells as non-hematopoietic stem cells from the mesoderm mostly come from the bone marrow, which have a stronger self-renewal ability, multilineage differentiation ability and low immunogenicity and are easy to receive the introduction of foreign genes. Therefore this kind of cells have become the research hotspot in recent years. OBJECTIVE:To summarize the latest clinical application and advancement of bone marrow mesenchymal stem cels in the treatment of various diseases. METHODS: PubMed (http://www.ncbi.nlm.nih.gov/PubMed) and SinoMed (http://www.sinomed.ac.cn/zh/) databases were searched by the first author using the keywords of bone marrow mesenchymal stem cells, therapy to identify the relevant articles published in English and Chinese, respectively, from 2011 to 2016. After excluding repetitive, irrelevant or Meta-analysis literatures, we enrolled 49 literatures for final analysis. RESULTS AND CONCLUSION:Studies on bone marrow mesenchymal stem cells have achieved new grades in the treatment of respiratory system disease, cardiovascular disease, urinary system disease, nervous system disease, liver disease, diabetes mellitus, hematological system disease, autoimmune disease, graft-versus-host disease, motor system disease, although its application has the risk of oncogenicity. Further investigation on the oncogenicity of bone marrow mesenchymal stem cells will be gradually explored, aiming to a better clinical use of bone marrow mesenchymal stem cells.

Objective To evaluate the clinical significance of high frequency ultrasonography in the diagnosis of annular pancreas in neonates.Methods Ultrasound results,clinical data,operation results and complicating deformity of 19 neonates were reviewed retrospectively.The digestive tracts of 19 neonates,including stomach,duodenum,jejunoileum and colon,were examined with 8-12 MHz linear transducer before surgery.Results Of 19 neonates with annular pancreas,17 cases were diagnosed with ultrasound,the diagnostic rate was 89％.The pancreas tissue encircling the descending duodenum was directly displayed as a direct sign of ultrasonography and the expansion of the proximal end of the duodenum was presented as an indirect sign of ultrasonography in 17 neonates.There were 3 neonates with annular pancreas complicating intestine malrotation and 2 neonates with annular pancreas complicating duodenal membraneous stenosis.One neonate was misdiagnosised and the other was missed.Conclusions High frequency ultrasonography plays an important role in diagnosing annular pancreas and other digestive deformity in neonates.It can be used as the first choice for the neonatal annular pancreas.

BACKGROUND: The contact lenses were easily contaminated by adsorbing components from the tear film, particularly protein after wearing for a period of time. Lysozyme adsorption dynamics of fluorosilicone acrylate contact lenses has been studied in order to further improve data of protein adsorption, reduce adsorbing amount of surface protein, and prevent surface contamination of contact lenses.OBJECTIVE: To investigate the adsorption dynamics of fluorosilicone acrylate contact lenses to lysozyme in vitro. METHODS: A stock solution of lysozyme was prepared in Hanks balanced salt solution (2.0 g/L, solution Ⅰ) and different trifluoroacetic acid (TFA) concentrations were prepared. Recovery experiment, the contact lenses were placed in shaking incubator at 37 ℃ for varying time intervals. After incubation there was a single rinsing in Hanks balanced salt solution. Contact lenses in control group were placed in diluted water, and contact lenses in the other group were placed in different concentrations of TFA. For deposition, FSA contact lenses in experimental group were placed in shaking incubator at 37 ℃ for varying time intervals. After incubation there was a single rinsing in Hanks balanced salt solution. Then FSA contact lenses were immersed in 0.2% TFA solution. The amount of lysozyme was assayed with BCA method.RESULTS AND CONCLUSION: Lysozyme which attached to fluorosilicone acrylate contact lenses could be resolved by TFA, and the recovery was influenced by the immersed time and the concentration of TFA. The optimal time was 1 hour, and the optimum concentration was 0.2%. The adsorption dynamics of lysozyme on FSA contact lenses was a second-phased process, i.e., lysozyme adsorption increased rapidly during 10 minutes-1 hour, reached a plateau at 1 hour, stably adsorbed during 1-24 hours, and reached a saturation of 0.349 mg/cm~2. The recovery of lysozyme was lower at 10 and 30 minutes, but reached 90%-100% while the time of incubation was between 40 minutes and 24 hours.

Objective To investigate the characteristics of the bone marrow mesenchymal stem cell(MSC)in children with aplastic anemia(AA)in vitro,and the expressions of tumor necrosis factor -α-induced protein -8 -like 2(TIPE2)in the bone marrow,and the correlation between the level of TIPE2 mRNA with γ-interferon(IFN -γ)and IL -6 in AA patients.Methods Bone marrow samples were collected from 1 8 children with AA(AA group)and 8 children with bone injury (control group)who were hospitalized in Jinan Children′s Hospital from January 201 2 to June 201 5.MSC were isolated and cultured.The morphology of MSC was observed and immune phenotype was detected.The TIPE2 mRNA was detected by using real -time fluorescence quantitative PCR,and the levels of IFN -γand IL -6 were detected by using enzyme linked immunosorbent assay.Results Different sizes had been presented in the primi-tive MSC of AA patients,but the third passage MSC until 80% confluence had manifested the uniform convergence with long spindle and swirl distribution.In the sixth passage,cells showed degenerative change.The primitive and first pa-ssage MSC in patients with AA was longer than that in the controls.CD73 ,CD1 05 ,CD44 and CD90 were expressed in MSC,while CD34 ,CD45 ,CD271 expressed rarely.The level of TIPE2 mRNA in AA patients (5.29 ±1 .56)was obviously lower than that of the control group(8.68 ±2.00),and the difference was significant(t =-4.48,P <0.01 ).The con-centration of IFN -γ[(5.48 ±1 .97)ng/L]and IL -6[(5.43 ±1 .92)ng/L]in AA patients were higher than those of the control group[(3.40 ±1 .24)ng/L,(3.79 ±0.92)ng/L],and the differences were significant (t =2.70, 2.26,all P <0.05).The level of TIPE2 mRNA in AA patients was negatively related with IFN -γand IL -6(r =-0.838,-0.658,all P <0.05),but there was no significant correlation between them in the control group (all P >0.05).Conclusions The proliferation of MSC is significantly reduced in patients with AA.TIPE2,as an important role to stabilize the immune system,plays an important role in the occurrence of AA by its low expression and up -regula-ting the expression of inflammatory factors.
