The occurrence of epilepstic seizures in patients with cerebral palsy (CP) remains a serious event and is very disruptive for children who already suffered from orther disabilties. Data from population-based studies or neurodevelopmental clinic studies showed that 8%～62% of patients with CP suffer from epilepsy. The incidence is highest in spastic tetraplegia and hemiplegia. Half of the patients were onset within the first year of age. Children with tetraplegia CP tended to have an earlier onset of epilepsy than chlidren with other CP types. Partial seizures were the most common seizure types, followed by infantile spasms and Lennox-Gastaut syndrome. Low birth weight, neonatal seizures, family history of epilepsy, lower intelligence and grey matter damage were found to be related to significantly increased risk of epilepsy. Epilepsy in children wih CP usually had poor outcome, half of them were intractable and needed polytherapy. Only 37%～65.2% of patients became seizure-free.

Nanoparticle delivery systems have good application prospects in the field of precision therapy, but the preparation process of nanomaterial has problems such as short in vivo circulation time, easy recognition, and clearance by the immune system in the body. In recent years, biomimetic nanoparticle delivery systems mediated by natural cell membranes have become a research hotspot to address these issues. The natural membrane biomimetic nanoparticle delivery system cleverly integrates the advantages of natural biofilm "autologous" and "artificial" functional carriers by using endogenous cell membranes to modify the surface of nanocarriers, endowing them with characteristics such as tumor targeting, low immunogenicity, and long blood circulation. Currently, biomimetic nanoparticle delivery systems have been used in the treatment of malignant tumors, cardiovascular diseases, bacterial infections, and other diseases. This paper analyzes the development status and current research hotspots of natural cell membrane camouflaged biomimetic nanoparticle delivery systems mainly reviews the latest research progress of red blood cell membrane camouflaged biomimetic nanoparticle delivery systems in the field of disease treatment in recent years. It focuses on exploring the advantages, future development prospects, and limitations of biomimetic nanoparticle delivery systems based on red blood cell membrane camouflage in improving drug delivery, to provide a reference for the in-depth research and development of this system.

Objective To observe the effect of exhaustive exercise on the function of the kidney in rats and explore the mechanism. Methods Fourteen male Sprague-Dawley rats were divided into sedentary control group (group C) and exhaustive exercise group (group E). They were measured the urine protein, uric acid, glucose, and blood urea nitrogen after exercise. The reactive oxygen species, inducible ni-tric oxide synthase, nitro tyrosine in kidney, and nephrin protein in the kidney were detected with fluorescent probe and Western blotting, re-spectively, and observed under Harris staining. Results There were significant differences between groups C and E in urine protein, uric ac-id, glucose, blood urea nitrogen, reactive oxygen species, inducible nitric oxide synthase, nitrotyrosine and nephrin protein (P<0.05). The glomerular morphology and the deformation of capillary basement membrane were found under the fluorescence microscope in group E. Conclusion Exhaustive exercise may damage the structure of kidney in rats, which may associate with oxidative stress.

Objective To analyze the prevalence of the various hematological malignancies (HM) in Harbin.Methods Study data was collected from January 2010 to December 2011.All cases were diagnosed and classified on the basis of blood test,bone marrow puncture,histochemical staining and typing and classified by the French American British classification.The age and sex distribution of HM and its subtypes were analyzed.Results Of 2214 Chinese people diagnosed with HM,acute myeloid leukaemia (AML) (33.5 ％) and myelodysplastic syndromes (MDS) (29.9 ％) were the most prevalent and of 742 AML,the most frequent subtypes were M3.With the growth of age,the rates of chronic lymphocytic leukemia (CLL) and multiple myeloma (MM) were increased,but in acute lymphocytic leukemia (ALL),this trend was reversed.The distribution of HM increased with age between 0-60 years old,in above 60 years old,the frequency of some chronic HM including CLL,chronic myelomonocytic leukemia (CMML),chronic neutrophilic leukemia (CNL) and MM were continued to rise,but other HM subtypes were decrease,lower than in 41-60 years old groups.This study also revealed that M0 and MPAL were more common in 0-20 years as well as ALL.For patients never drinking alcohol and drinking for at least 10 years maybe associated with acute leukemia [OR =1.53 (95 ％ CI 1.05-2.23)],while smoking wasn' t a substantial risk factor for acute and chronic leukemia (P =0.20,0.48).Conclusions The epidemiology of HM in Harbin indicates that AML is the most prevalent,followed by MDS.Prevalence of CLL and MM increases with the age in patients above 60 years old.Drinking for at least 10 years maybe associated with acute leukemia.

Objective To explore the thyroid function changes of episodes period and remissions period in children with primary nephrotic syndrome (NS).Methods The urinary protein quantitation and serum albumin,total cholesterol,thyroid hormone level [total triiodothyronine (TT3),total thyroxine (TT4),free triiodothyronine (FT3),free thyroxine (FT4) and thyroid stimulating hormone (TSH)] of episodes period and remissions period in 15 children with primary NS were retrospectively analyzed.Results There were statistical differences in urinary protein quantitation and serum albumin,total cholesterol in children with NS between episodes period and remissions period (P ＜ 0.05).The TT3,TT4,FT3,FT4 in episodes period were significantly lower than those in remissions period [(0.6 ± 0.3) μ g/L vs.(1.3 ± 0.3) μ g/L,(40.0 ± 23.0)μ g/L vs.(68.0 ± 15.0) μ g/L,(1.6 ± 0.3) pmol/L vs.(3.3 ± 0.3) pmol/L,(8.6 ± 2.5) pmol/L vs.(12.2 ± 2.0) pmol/L],TSH was significantly higher than that in remissions period [(5.6 ± 2.1) mU/L vs.(2.5 ± 1.1) mU/L],there were statistical differences (P ＜ 0.05).Conclusions Thyroid function of episodes period in children with primary NS is decreased temporarily,associated with heavy proteinuria leads to thyroid hormone missing from urine.Detecting thyroid function plays an important role in estimating the state and guiding the treatment of primary NS.

This study aimed to identify Belamcandae Rhizoma, Iridis tectori Rhizoma and their adulterants by ITS2 sequence. All the DNA samples of Belamcandae Rhizoma, Iridis tectori Rhizoma and their adulterants were extracted. The ITS2 sequence were succesfully amplified, and purified PCR products were sequenced. All the sequences were assembled using the CondonCode Aligner V3.7.1. The Kimura 2-Parameter (K2P) genetic distances and the Neighbor-Joining (NJ) phylogenetic tree were calculated by using MEGA5.1. Results indicated that the maximum intraspecific genetic distances of Belamcandae Rhizoma was 0, and the average GC content was 52.22%;the maximum intraspecific genetic distances of Iridis tectori Rhizoma was 0.004, and the average GC content was 67.87%. The maximum K2P intraspecific genetic distance of Belamcanda chinensis, Iris tectorum were both lower than the minimum interspecific genetic distance of adulterants. Additionally, the ITS2 sequences in each of these polytypic species were separated into pairs of divergent clusters in the NJ tree. The NJ tree based on ITS2 sequence indicated that Belamcandae Rhizoma, Iridis tectori Rhizoma and their adulterants could be distinguished clearly. It could be concluded that ITS2 barcode can be used to correctly identify Belamcandae Rhizoma, Iridis tectori Rhizoma from their adulterants, and ensure their safety in use.
