Since recent years, the incidence of precocious puberty has been rising. However, questions regarding its treatment and other conditions remain. This article reviews recent published papers with long-term outcome data and guidelines, and systemical introduction to identification of precocious puberty, different treatment options, therapeutic goals, and indications for different types of diseases, as well as adverse effects of drugs.

This article reviews the long-term outcome data and guidelines up to date, and systemically reviews the effect of ω-3 long-chain polyunsaturated fatty acid consumption, the major effective component in deep-sea fish oil, on metabolic syndrome, including improvements in abdominal obesity, insulin resistance, dyslipidemia, and hypertension, etc. Its adverse effects are also commented.

Objective To establish a method for simultaneous determination of 6 kinds of organophosphorus pesticides in water.Methods The liquid-liquid extraction,gas chromatography with RTX-50 capillary column and flame photometric detector were used to determine 6 kinds of organophosphorus pesticides(DDVP,dimethoate,malathion,methyl parathion,parathion,chlorpyrifos)in water.Results Chromatographic resolutions for the above 6 kinds of organophosphorus pesticides were both over 1.5.The linear range was 2.0-16.0 ?g/ml(r=0.999 2～0.999 8),the detection limits were 0.009 2～0.076 ng,RSDs were 1.5%-7.1%,the average recovery rates were 93.0%-98.7%.6 kinds of organophosphorus pesticides could be absolutely separated on RTX-50 capillary column.Conclusion This method presents an advantage in detection limit,precision and accuracy compared with that in GB13192-1991,it will meet the requirement of Sanitary Standard for Drinking Water and routine water quality analysis.

Objective To review the correlation between serum uric acid (UA) level and Parkinson's disease(PD) based on the papers published from 2004 to 2014 at home and abroad,with an attempt to provide new ideas for the early diagnosis and disease evaluation of PD.Methods Major online database including PubMed,CNKI,and Wan Fang date bases were searched in March 2014.The key words we used are uric acid,Parkinson' s disease and so on.Results Totally 28 studies were enrolled,the analysis showed there were argument on the correlation UA and PD,the effect of uarthritis on PD and the effect of antiparkison drugs on UA.Conclusion It is testified in most studies that UA level is obviously lower in PD patients.The variation of UA perhaps affects the morbidity,condition and non-motor symptom among patients with PD.However,the studies are limited by the research methods 、the public surveyed and other factors.

Objective To investigate the clinical efficacy and safety of montelukast combined with budesonide in the treatment of children with asthma. Methods 70 cases of children with asthma were randomly divided into group A and group B, included 35 cases in each group. Group A was treated with single budesonide and Group B was given montelukast combined with budesonide. The clinical efficacy of two groups of asthma was compared, the body temperature returned to normal time, the time of wheezing disappeared, the normal time of the laboratory index, the normal time of the chest radiograph, the inflammatory factors and the lung function indexes and the side effects. Results The clinical curative effect of group B was higher than that of group A(P<0.05); Body temperature in group B returned to normal time, the time of wheezing disappeared, the normal time of laboratory index was shorter than that of group A(P<0.05); Inflammatory factors and lung function were similar. After intervention, the inflammatory factors and lung function of group B were better than those of group A(P<0.05). There were no obvious side effects in the two groups. Conclusion The clinical efficacy and safety of montelukast combined with budesonide in the treatment of children with asthma can improve the symptoms of children, cause the symptoms to recite in a short time, reduce the inflammatory factors, improve lung function, no obvious adverse reactions, safety effective.

Pulse wave velocity (PWV) is one of typical indicators to evaluate arterial stiffness.About the gender difference of pulse wave velocity,some controversies exist.In this paper,several factors affecting the differences such as height,aging,sex steroids,which affect the arterial structure and function and bring the gender difference,are reviewed relatively in detail.In addition,several aspects including measurement accuracy,analyzing method and the characteristics of sample population,which may induce the difference of PWV results,are also briefly reviewed.Meanwhile,some existing controversies are indicated objectively to further possible research interests in this field.

Objective To survey the influence of nursing intervention on cognition level for pressure sores and psychological state among accompany family members of patients with cerebral injury. Methods 123 accompany family members of patients with cerebral injury were selected and took part in the investigation about cognition level for pressure sores, besides, SDS and SAS were also adopted to evaluate their psychological state. Later nursing intervention was given to increase their cognition level for pressure sores, then another evaluation was carried out. Results before and after the intervention were compared. Results The accompany family members lacked knowledge of pressure sore, showed serious anxiety and depression for nursing pressure sore before intervention. But their cognition level for pressure sore improved and anxiety and depression lightened after intervention. Conclusions Nursing intervention is effective to alleviate cognition level for pressure sore and psychological state among accompany family members of patients with cerebral injury, which is worthy of clinical application.

The environmental pollution caused by organo tin attracted much concern,at the same time, the methodological study on determination of organo tin in environment made a desirable development, the chromatograph technique was used widely.A more detailed review on application of gas chromatograph and its coupled techniques in the environment organo tin compounds analysis was presented in this paper.

Objective To explore the correlation of pathological changes and imaging through a control study on pathology and imaging of 4 cases of senile dementia of the Alzheimer type (SDAT).Methods By HE and Gallyas silver dyeing,four immunohistochemical methods were carried out The loss of neurons cells of all lobes of cerebral cortex,cingulate gyrus,amygdaloid nucleus,hippocampal gyrus,parahippocampal gyrus,meynert basal nucleus,substantia nigra,locus ceruleus,dorsal nucleus of vagus nerve,senile plaques (SP) and the changes of neurofibrillary tangles (NFT) were observed in detail The control study of pathology and imaging was carried out by comparison of CT in different phases before and after death of the patient.Results The degeneration of temporal lobe was marked: (1) The degeneration of middle frontal gyrus of cortex of frontal lobe was the most evident; (2) The degeneration of long gyrus was more evident than that of the short gyrus as the cortex of insular lobe was concerned; (3) The degeneration posterior part of cingulated gyrus was more evident than that of the anterior part.Conclusion The pathological findings of SDAT mentioned above are basically in conformity with the changes of imaging.

Objective To study of the effect of traditional Chinese medicine(TCM): Herba radix polygoni multiflori preparata (RPMP) on the cultured melanocytes(MC). Methods Extracts of TMC RPMP treated the cultured melanocytes, and tyrosinase activity, melanin level and proliferation of the cells were determined. Meanwhile, method of micropore filter was used to measure the ability of cell migration. Results TCM RPMP markedly promoted the proliferation and migration of MC in a dose-dependent manner at a range of 0～150?g/ml. Conclusions TCM RPMP can promote the proliferation and migration of MC in vitro. And it suggests that this drug could be used to treat vitiligo.
