RESULTS:Totally 10,14 and 48 volatile components were identified from the root,stem and leaf,which accounted for 90.03%, 92.79% and 95.93% of the capacity of the total essential oil from each part of it. And totally 51 volatile compounds was identified, including 7 kinds that shared the same chemical components that regard the piperitone oxide as the main ingredient. CONCLU-SIONS:The method is simple,stable and reproducible,and can be used for the analysis of volatile components of different parts of M. haplocalyx. The volatile components in different parts are quite different,and most is in the leaf.

Objective:To evaluate levels of intelligence in children with ADHD. Methods:A total of 129 children with ADHD and 87 normal children were evaluated with C-WISC. Results:Full-scale IQs of most children with ADHD varied between the normal and borderline range, showing incompatible scores on VIQ and PIQ. The overall levels of intelligence of children with ADHD were found be lower than normal controls. Conclusion:There was significant difference in intellectual abilities between ADHD children and normal children.

Objective: To study the relationship between inteiligence and ADHD (attention deficiency and hyperactivity disorder) . Method: 129 children with ADHD and 87 normal control were evaluated with C- WISC. Results: The IQ of some children with ADHD was in borderline range, their performance of balance between VIQ and PIQ was poor. While the controls had normal IQ. Conclusion: The IQ of children with ADHD is lower than that of normal children, especially the balance between VIQ and PIQ.

Group A β-hemolytic streptococcus (GAS),namely Streptococcus pyogenes,is one of the most im-portant human pathogen.GAS can cause skin and mucous membrane superficial infectious diseases,life -threatening invasive disease,toxin -mediated diseases and immune -related diseases.Antibiotic is an effective mean to control GAS infection.The β-lactam antibiotics remain the first -choice treatment for GAS infection and the macrolides are often recommended as a replacement therapy for β-lactam antibiotics allergic patients or a means to blocking GAS exotoxin product.But with the widespread use of macrolides autibiotics,macrolide -resistant GAS spread in the world. This paper will elaborate the situation of macrolide -resistant clones.

Axillary lymph node status isone of the most important prognostic factors for the patients with breast cancer.Physical examination combining with ultrasound, mammography, CT, MRI and PET-CT can improve the predictive efficiency, but there is still high false negative rate.Ultrasound-guided fine-needle aspiration for axillary lymph node can improve preoperative diagnostic rate effectively.Using mathematical and statistical methods, building models for predicting sentinel lymph node or non-sentinel lymph node status with clinicopathological features helps to calculate the risk of lymph node involvement.Whether screening out patients with low risk of lymph node involvement avoiding axillary surgery is safe or not is still to be evaluated by relevant clinical trials.

Objective To investigate the relationships among cerebellar mutism (CM), relapsed medulloblastoma (MB) and the primary tumor location.MethodsA retrospective analysis was conducted in 114 children over 3 years old with MB from November 2011 to April 2015.ResultsThe median onset age was 84.7 months (36.4 to 184.7 months) in 114 children with MB (77 boys and 37 girls), of whom there were 48 cases of recurrence. There were twenty two cases of CM and the overall incidence of CM was 19.3% (22/114). The incidence of CM was 19.7% (13/66) in non-recurrent cases and 18.8% (9/48) in recur-rent cases, and there was no signiifcant difference between two groups (P=0.899). The incidence of CM was 17.6% (9/51) in cas-es with primary tumor in the fourth ventricle, 7.1% (1/14) in cases with primary tumor in the cerebellar vermis, 21.4% (3/14) in cases with primary tumor in both fourth ventricle and cerebellar vermis, 45.5% (5/11) in cases with primary tumor in fourth ven-tricle and other parts of the brain, and 50.0% (4/8) in cases with primary tumor in cerebellar vermis and other parts of the brain. No CM incidence was observed in cases with primary tumor in central nerve system except for the fourth ventricle and cerebellar vermis. The incidence of CM between the cases with fourth ventricle/cerebellar vermis involvement and those without fourth ventricle/ cerebellar vermis involvement had signiifcant difference (P=0.039). ConclusionsThere is no relationship between CM and relapsed MB. Children with MB whose primary tumor is located in the fourth ventricle and/or the cerebellar vermis is susceptible to CM.

At present, there are many effective ways to achieve high performance in cluster system storage management, including server-end disk, server-end caching, local caching and cooperative caching. The cooperative caching mechanism shares caches among different clients so as to avoid expensive disk access costs and to improve overall throughput of cluster system. In this paper, a Single Copy Cooperative Cache model is proposed together with block lookup algorithm, block replacement algorithm and the consistency algorithm based on the model. Meanwhile, the prototype system of the model is implemented in PVFS file system. Finally, the performance of this system is tested in InfiniBand Framework, the result of which shows that in contrast to the original PVFS system, read performance of PVFS file system is improved by about two times, while write performance is reduced by nearly ten percent.

Objective To investigate the role of insulin resistance in patients with prostate cancer who received surgical castration. Methods Sixty-seven patients with advanced prostate cancer who received with surgical castration were divided into obesity group [30 cases, BMI (26.85±1.22) kg/m2] and non-obesity group[37 cases, BMI(22.72±1.28) kg/m2]. The fasting blood glucose (FBG) and the fasting serum insulin, while evaluated the insulin resistance index(IRI) were determined before treatment, 6 months after treatment and 12 months after treatment. Results The levels of fasting serum insulin were significantly higher 6 months[(23.21±5.78 )mU/L] and 12 months [(24.34±5.37) mU/L] after treatment than that be-fore treatment[(20.01±4.82) mU/L] in obesity group, but 12 months after treatment [(22.19±6.14) mU/L ]was higher than that before treatment [(17.36±6.01) mU/L] in non-obesity group (P<0.01). The IRI were significantly higher 6 months (2.94±0.79) and 12 months (3.10±0.73) after treatment than that be-fore treatment (2.53±0.64) in obesity group, but 12 months after treatment (2.79±0.75) was higher than that before treatmeat(2.17±0.73) in non-obesity group(P<0.01). Conclusion The current data suggests that the patients with prostate cancer who received surgical castration is at risk for developing insulin resistance, thus leading to increasing risk of cardiovascular disease and type 2 diabetes mellitus.

Objective To regulate standardized ICD-10 case classification name and coding,and common clinical diagnosis name or expression of mapping rules,to systematically improve the quality of DRGs key data,and to assess the impact of medical diagnostic data quality on DRGs and the indicators based on the DRGs.Methods Extension of the glossaries of clinical diagnosis synonyms or near-synonyms,and establishment of a standardized maintenance procedure of ICD-10 dictionary.Adjustment of the impact extent of DRGs disease makeup on case classification,comparison of the consistency of principal diagnosis classification,and the consistency of DRGs grouping,as well as changes of such indicators as DRGs grouping reduction in variance (RIV) and case mix index (CMI).Results Data of the obstetrics,gynecology and pediatrics disciplines of a maternity and children hospital from 2012 to 2013 (72 005 cases)and 2014 to 2015 (77 705 cases) were chosen for prior-after comparison.The encoding consistency rate was 59.60％ before the improvement,with the improved standardized consistency rate rising to 66.38％afterwards;beforehand the DRGs grouping consistency rate was 69.30％,with the improved standardized consistency rate rising to 88.00％ afterwards;beforehand the cost RIV was 0.515,with the cost RIV rising to 0.576 afterwards;the CMI variations of individual campuses of healthcare institutions appear more reasonable.Conclusions Diagnostic quality control and improvement project can improve the data accuracy of coding.This empowers the RIV and CMI indexes calculated on such basis to better describe the complexity of clinical settings,conducive to establishing a value-oriented prepayment system which is more transparent,fair and reasonable.
