The aims of this paper were to define (1) criteria of cerebral palsy; (2) classification of cerebral palsy; (3) etiology, neuroimaging, and epidemiology of cerebral palsy; (4) different kinds of treatments of cerebral palsy. Data were drawn from an international survey of PUBMED (1994-2014) and CNKI (1994-2014). An expert panel used a consensus building technique. The10-point Jadad scale was used to assess the quality of the trials based on the following items, including allocation sequence generation, randomization concealment, methods of blinding, and descriptions of withdrawals and dropouts. Our clinical experience was also summarized. Below is a summary. (1) Further work is warranted to reach agreement for the classification of cerebral palsy. (2) A worldwide prevalence of 1.5-4.0 per 1 000 live births, with an average lifetime cost of 1 million dollars per person in the United States, while it is 1.8-6.0 per 1000 live births in China. (3) Comparison of clinical efficacy of different treatments. In this review, the current advances in different kind of treatments of brain injury are discussed with specific relevance to cerebral palsy.

Objective To investigate the presence of occult brain tissue damage in patients with relapsing neuromyelitis optica(RNMO)and its possible mechanism by using diffusion tensor imaging (DTI).Methods DTI scans were performed in 16 patients with RNMO and 16 sex-and age-matched healthy controls.Histogram analysis of mean diffusivity (MD)and fractional anisotropy (FA)was performed in brain tissue (BT),white matter (WM)and gray matter (GM)to detect the presence of occult brain tissue damage in RNMO patients.Region of interest(ROI )analysis of MD and FA was also performed in 6 dedicated regions with or without direct connection with spinal cord or optic nerve to determine the relationship between occult brain tissue damage and the damage of spinal cord and optic nerve.Results Patients with RNMO had a significantly higher average MD of the BT[RNMO(0.95?0.02)? 10~(-3)mm~2/s,controls (0.91?0.03)?10~(-3)mm~2/s,t = 3.940,P

OBJECTIVETo explore biomechanical properties and stress-strain of mucosa scars after cleft palate surgery.

METHODSAfter the model of mucosa scars was made, the mucosa scars and normal mucosa were excised and examined immediately by tensionometry.

RESULTSThe mucosa scars after cleft palate surgery were compared with normal mucosa. The Poisson's ratio of mucosa scars and normal mucosa was 0.5 and 0.49, respectively, showing no significant difference between the two groups. The ultimate Young's modulus of mucosa scars was about 24.22 MPa, however, it declined to 3.32 Mpa in normal mucosa.

CONCLUSIONSThe mucosa scars after cleft palate surgery are biomechanically weaker than normal mucosa. It can be used for further research, such as maxillary orthognathic surgery, distraction osteogenesis, and orthodontic treatment.

Though parched Chinese herbal medicines contain less effective or index components, their pharmacological actions do not reduce or even become improved to some extent. However, the current studies related to material basis could not explain the changes in property, flavour and efficacy of parched Chinese herbal medicines. Meanwhile, due to the lack of objective and specific evaluation indexes, the quality evaluation could not reflect features of parched Chinese herbal pieces. Therefore, how to break the bottleneck for the studies on parched Chinese herbal pieces, make further innovation and conduct in-depth studies on the material basis of parched Chinese herbal medicines are common problems that medical scholars are facing. According to the findings in the previous studies, the author proposed to explain the material basis of parched Chinese herbal medicines by studying Maillard reaction and establish specific quality evaluation indexes according to the features of parched Chinese herbal pieces, and conducted relevant studies.

OBJECTIVETo analyze the reliability and validity of the Fatigue Self-assessment Scale (FSAS).

METHODSThe scale was applied among the participants assigned to 4 groups, the differences in types, degrees and characteristics of fatigue of them were compared, and the reliability and constitutional validity of ESAS were assessed by internal consistency analysis, exploratory factor analysis and confirmatory factor analysis using the statistical software of SPSS and LISREL.

RESULTSStatistical differences of types, degrees and characteristics of fatigue presented in the participants of the 4 groups. The Cronbach's alpha of various factors in the scale were 0.772-0.908; the indexes for the section of assessing type, and degree of fatigue were RMSEA=0.065, NNFI=0.95, CFI=0.96; and those for the section of assessing characteristics of fatigue were: RMSEA=0.10, NNFI=0.93, CFI=0.96.

CONCLUSIONThe FSAS has good differentiability, reliability and constitutional validity for assessing the type, degree and characteristics of fatigue in various populations. In order to explore the relationship of TCM syndrome patterns with the type, degree and characteristics of fatigue, its future application for evaluation of fatigue and intervention effect of anti-fatigue should be combined with TCM syndrome differentiation.

Objective To evaluate the effect of multiple intervention measures on perioperative antimicrobial use in pa-tients undergoing typeⅠincision operation in a hospital,and provide basis for rational use of antimicrobial agents. Methods 9 823 patients with type I incision operation in April and October of 2005-2012 were surveyed retrospectively, data of 2005 was as baseline,from 2006 to 2012,multiple measures,including training,examination,supervision,feed-back,and cooperation of relevant departments were conducted,antimicrobial use before and after intervention was com-pared.Results The qualified rate of perioperative antimicrobial use in patients undergoing typeⅠ incision operation in-creased from 14.20% in 2006 to 92.30% in 2012;the rate of combined use of antimicrobial agents was relatively higher (7.00%-9.00%)in 2006-2009,had a downward trend in 2010- 2012,and decreased to 3.20% in 2012.Types of an-timicrobial agents for prophylactic use in typeⅠincision operation in 2006 and 2007 were similar to that of 2005,the main used antimicrobial agents were cephalosporins,penicillin and it’s compounds,and aminoglycosides;the major antimicrobial prophylaxis in 2008-2012 were the first and second generation cephalosporins,penicillin and it’s compounds.Multivariate non-conditional logistic regression analysis showed that age (40 - 59 years old),departments (orthopedics,general surgery,and ophthalmology),and years (2011 and 2012)were the main influencing factors for the qualified use of antimicrobial agents(all P<0.05).Conclusion Implementation of multiple intervention measures can improve the qualified rate of perioperative antimicrobial use in typeⅠ incision operation,reduce types of antimicrobial use and rate of combined antimicrobial use.

Cryogel is a kind of elastic, spongy hydrogel prepared via addition polymerization from monomers or cross-linking reaction from a polymer at a temperature lower than the freezing point of the solvent. Cryogel has been principally used in molecular imprinting cryogel based solid phase extraction in the field of analytical chemistry, which combines both the advantages of high selectivity of the molecular imprinting and the porous structure, high throughput of a cryogel. Molecular imprinting cryogel can be used as the stationary phase in a packed column, a monolith column, or the adsorbent in a separation membrane. A variety of molecules can act as template molecules, including small molecules, macromolecules, a certain fragment of a macromolecule, and even an inorganic ion. Both a simple template and a complex template can be used. When employing more than a molecule ( or an ion) as templates simultaneously, the method is termed as Mixed template. While high abundance components of a complex sample act directly as mixed template, we name the method as Pending template. Further, while an analogue, an isotopic label, or a fragment of the target substance acts as a template, the method is defined as Dummy template. However, the research on cryogel is insufficient and the application of the cryogel is narrow hitherto.

Objective To improve the awareness of fetal cardiac rhabdomyomas (CRs) and investigate a better model for prenatal diagnosis and treatment through analyzing imaging findings and prognosis.Methods A retrospective study was conducted on 23 cases of CRs which were diagnosed by ultrasound in Obstetrics and Gynecology Hospital of Fudan University from January 2008 to November 2015.General conditions,imaging features,prognosis and follow-up data of the 23 cases were described.Results The average gestational age of the 23 fetuses at diagnosis was (29.8±4.1) (22.4-35.7) weeks.Seventeen out of the 23 gravidas received prenatal multidisciplinary consultation.Among all 23 gravidas,three (13％) were lost to follow-up,12 (52％) decided to terminate the pregnancy,and the other eight (35％) continued to term pregnancy and their babies were followed up for three years.Of these eight cases,two cases received prenatal brain MRI and no tuberous sclerosis complex (TSC) was detected,no CRs was identified during the follow-up,and their physical and mental developments were both normal.One case was diagnosed with suspected subependymal nodules by prenatal brain MRI in our hospital,but the MRI images was normal when scanned in the other hospital,and follow-up data revealed neither CRs nor abnormal physical and mental developments.Four cases did not received prenatal brain MRI,but the MRI images of neonatal brains indicated TSC,besides,follow-up data showed that seizures were observed,physical developments were all normal,but three of the four cases had mental retardation;CRs disappeared in only two of the four cases.One case had neither prenatal nor neonatal MRI,but follow-up data showed that CRs had disappeared and physical and mental developments were both normal.Conclusions Prenatal diagnosis of fetal tuberous sclerosis is crucial to the prognosis of CRs.Prenatal ultrasonography in combination with cranial MRI improves the accuracy of prenatal diagnosis of CRs complicated with TSC and assists in clinical decision-making and prognosis analysis.

AIM: To investigate and analyze the status of visual fatigue of naval crew on continuous voyage, explore the risk factors related to visual fatigue, and build a decision tree model for visual fatigue prediction.

METHODS:A total of 373 naval fleet members were selected by stratified random sampling method from July to October 2016. By asking the medical history and basic personal information of the subjects, the naked eye visual acuity, the best corrected visual acuity, slit lamp examination including: eyelid, eyelid margin, meibomian gland changes, cornea and conjunctiva signs of ocular surface damage, and corneal fluorescein staining to determine the tear breakup time(BUT). The Ocular Surface Disease Analysis Scale(OSDI)and ocular fatigue questionnaire were filled in, the incidence and severity of ocular fatigue were counted, and the risk factors of ocular fatigue were analyzed.

RESULTS: Totally 63.0%(235)of the crew members had different degrees of visual fatigue. There was no correlation between asthenopia and gender, age and previous corneal refractive surgery(P>0.05); Dry eyes and exposure time of electronic screen were the risk factors(P<0.01). The overall prediction accuracy was 76.9%.

CONCLUSION: The exposure time of dry eye and electronic screen is the risk factor of visual fatigue in continuous navigation crew.
