ABSTRACT
Autoimmune or infectious diseases often instigate the undesirable damages to tissues or organs to trigger immune-related diseases, which involve plenty of immune cells, pathogens and autoantibodies. Nanomedicine has a great potential in modulating immune system. Particularly, biomimetic nanomodulators can be designed for prevention, diagnosis and therapy to achieve a better targeted immunotherapy. With the development of materials science and bioengineering, a wide range of membrane-coated nanomodulators are available. Herein, we summarize recent advancements of bioinspired membrane-coated nanoplatform for systemic protection against immune-related diseases including autoimmune and infectious diseases. We also rethink the challenges or limitations in the progress of the therapeutic nanoplatform, and discuss the further application of the nanomodulators in the view of translational medicine for combating immune-related diseases.
ABSTRACT
Objective To investigate the trend of early neural development in premature infants. Methods At the age of 12 months and 24 months, Bayley Scales of Infant Development were used to assess the mental development index (MDI) and the psychomotor development index (PDI) in preterm (corrected age) and full-term infants. Results At 12 months, there was no significant difference in corrected age PDI scores among different gestational age groups (<32 , 32–33+6 and 34–36+6 weeks) (P=0.820). The actual age MDI and PDI scores of full-term infants and premature infants in 34~36+6 weeks group were significantly higher than those of premature infants in <32 and 32-33+6 weeks groups, and the PDI score of full-term infants was significantly higher than that of premature infants in 34-36+6 weeks group (P<0.05). There was no significant difference in actual age PDI scores among different birth weight groups (P=0.166). The actual age MDI and PDI of full-term infants and premature infants in birth weight≥2500 g group were significantly higher than those of premature infants in <1500 g, 1500~1999 g and 2000~2499 g groups (P<0.05). At 24 months, the actual age MDI scores of full-term infants were significantly higher than those of premature infants in different gestational age and birth weight groups (P<0.05). The actual age MDI curve of premature infants in birth weight <1500g group showed a downward trend, while the actual age PDI curve showed a significant upward trend. Conclusion The neurodevelopment of preterm infants at the corrected age of 12 and 24 months reaches the level of full-term infants.
ABSTRACT
Objective:To investigate the rationality of prophylactic antibiotics application during perioperative period in the pa-tients with type Ⅱ incision operation in gynecology and obstetrics in our hospital after the intervention. Methods:Totally 274 medical records of obstetrics and gynecology patients with typeⅡincision operation in our hospital from April 2012 to March 2013 were collect-ed as the control group, another 321 medical records of obstetrics and gynecology patients with typeⅡincision operation in our hospital from April 2013 to March 2014 were collected as the intervention group. The rationality of prophylactic antibiotics application before and after the intervention was compared. Results:Compared with those in the control group, the average administration time, the hos-pitalization time and the cost of antimicrobial agents were significantly decreased in the intervention group (P0. 05). Compared with those in the control group, the incidence of irrational choice of antibacterial drugs, the combined use without indication, irrational medication time,over-time use, inappropriate use and improper choice of solvents in the intervention group was significantly reduced ( P<0. 05). Conclusion:After the intervention, the rationality of prophylactic antibiotics application during perioperative period in the patients with type Ⅱ incision operation in gynecology and obstetrics in our hospital is improved significantly.
ABSTRACT
Objective To investigate the diagnostic difference between preoperative diagnostic curettage and postoperative pathological diagnosis in endometrial carcinoma,and provide guidance for the accuracy in preoperative diagnosis of endometrial carcinoma.Methods The data of 124 endometrial carcinoma patients were retrospectively analyzed,including clinical stage,pathological stage,pathological type,histologic grade,etc.Results In 124 endometrial carcinoma patients,102 cases of endometrial carcinoma were found by preoperative diagnostic curettage,the diagnostic accordance rate was 82.3％ (102/124),misdiagnosis was in 22 cases,the misdiagnosis rate was 17.7％(22/124).The total accordance rate of preoperative clinical stage and postoperative pathological stage was 81.4％ (83/102) in 102 patients who had the same preoperative and postoperative diagnosis,and the accordance rate of Ⅰ stage was 86.1％ (62/72),the accordance rate of Ⅱ stage was 72.0％(18/25),the accordance rate of Ⅲ stage was 3/5.The total accordance rate of preoperative diagnostic curettage histologic grade and postoperative pathological histologic grade was 65.7％(67/102),and the accordance rate of G1 grade was 55.6％ (25/45),the accordance rate of G2 grade was 69.2％ (27/39),the accordance rate of G3 grade was 15/18.Conclusions The pathological type,pathological stage and histologic grade of preoperative diagnostic curettage and postoperative pathological diagnosis in endometrial carcinoma are not always consistent.A variety of diagnostic methods should be considered together in order to reduce the diagnosis difference preoperative and postoperative,and improve the accordance rate of preoperative diagnosis.
ABSTRACT
@#Objective To investigate the distribution of complications and the relationship with neurologic subtype and gross motor function in preterm infants with cerebral palsy (CP). Methods The type, grade of Gross Motor Function Classification System (GMFCS), intelligence,speech, ophthalmologic consultation, brainstem auditory evoked potential and electroencephalogram of 135 preterm infants with CP were reviewed. Results There were 284 complications in total, (2.10±1.33) per child, and was significantly different among various types of CP (F=5.50, P<0.001). The incidence of mental retardation and speech disorder was significant different among various types (P<0.05). The incidence of mental retardation, speech disorder, visual impairment and epilepsy increased significantly (P<0.05) in spastic quadriplegia infants,compared with those with diplegia and hemiplegia. The incidence of mental retardation, speech disorder, visual impairment and musculoskeletal disorder was significantly different (P<0.05) among various grades of GMFCS. The frequency of complications was more in children unable to walk (GMFCS Ⅳ~Ⅴ) than able to walk (GMFCS Ⅰ~Ⅲ) for children over 2 years old (t=70.05, P<0.001). Conclusion The incidence of mental retardation, speech disorder, visual and hearing impairment, secondary musculoskeletal disorder and the multiple disorders are related with neurologic subtype and/or the grade of GMFCS.
