ncreased. But it remains controversial how vaspin is correlated with insulin sensitivity. More studies based on large population are needed to identify the associ-ation between vaspin and insulin sensitivity.

Objective To investigate the influencing factors of children pneumonia hospitalization expense and provide refer‐ence for its expense control .Methods Path analysis was performed on the hospitalization expense and its influencing factors based on 927 pneumonia children in a hospital in Chongqing in 2011 .Results Multivariate regression analyasis showed that the influen‐cing factors of children pneumonia hospitalization expense were proportion of drug expense ,length of hospital stay ,type of pay‐ment ,admission condition ,therapeutic outcome and age .The coefficient of determination (R2 =0 .867 ,F=597 .552 ,P<0 .01) .Be‐sides ,proportion of drugs ,admission condition and therapeutic outcome had indirect effects by influencing hospital stay .The coeffi‐cient of determination (R2 =0 .506 F=330 .336 ,P<0 .01) .According to the total coefficient of path analysis ,the factors of influen‐cing hospitalization expense were listed in descending order as follows :proportion of drug expense ,length of hospital stay ,therapeu‐tic outcome ,type of payment ,admission condition and age .Conclusion Reducing drug proportion ,length of hospital stay ,and strengthening supervision on medicare patients′ expense are effective measurements to control children pneumonia hospitalization ex penses .

Natural polysaccharides are a kind of hydrophilic polymers.By grafting hydrophobic moieties to the polysaccharide backbone,could form self-assembled micelle with core-shell structure in aqueous by undergoing intramolecular or intermolecular association between hydrophobic moieties.The self-assembly micelles of amphiphilic polysaccharides provides a positive outlook for drug delivery systems with biodegradability,low antigenicity,good biocompatibility and so on.This review focus on biological activity of amphiphilic polysaccharide as self-assembly carriers,the principle of self-assembly of polymeric micelles,and the recent progress in hydrophobic modification of natural polysaccharides.

Hyperuricemia(HUA),which can induce oxidative stress,endothelial dysfunction,and inflammation,is closely relevant to the metabolic syndrome(MS),such as obesity,impaired fasting blood glucose,hyper-triglyceridemia,and hypertension. Moreover,HUA is of reciprocal causation with insulin resistance(IR). Here,for the prevention and treatment of metabolic diseases such as HUA and MS,the interaction and the regulatory mechanism between MS and HUA are summarized,and the situation that HUA is an important complication of MS is illustrated.

Objective To investigate the pathological features of Lewy body disease. Methods An autopsy case of an 80 year old Chinese woman suffering from Lewy body disease was studied The patient had progressive dementia and myotonia for three years and was suspected with Alzheimer dementia clinically Brain tissue was analyzed neuropathologically by using HE staining and specific staining for nervous system, immunohistochemical staining for ubiquitin and by using ? synuclein and electronic microscopy. Results Neuropathological examination revealed the most characteristic features as follows: (1) The number of melanin pigmented neurons were markedly decreased in the substantia nigra and locus ceruleus, and some typical brain stem type Lewy bodies in the residual neurons with moderate gliosis were found (2) There appeared numerous cortical type Lewy bodies in deep layers of the cerebral cortex particularly in the cingulate gyrus, hippocampus, parahippocampal gyrus, transentorhinal contex, amygdala and insula (3) There were selective spongiform changes and many Lewy related neurites in positive ubiquitin immunohistochemical staining on the CA2/3 sectors, parahippocampal gyrus and transentorhinal cortex (4) A strong positive ? synuclein immunoreactivity was found in all Lewy bodies and Lewy related neurites (5) Alzheimer disease related changes such as senile plaques and neurofibrillary tangles were scarcely found only in hippocampus and parahippocampal gyrus. Conclusion Lewy body disease is a new group of degenerative disease of the central nervous system ? synuclein may play an important role in the degeneration of neurons and their neurites may be a major component of Lewy bodies in Lewy body disease It is considered that the present case should be a pure type of diffuse Lewy body disease

Objective To investigate the environmental factors affecting neonatal neurobehavioral development and its sensitivities.Methods Neonatal behavioral neurological assessment (NBNA)and lead levels in umbilical cord blood and meconium were determined for103randomly selected neonates delivered at the section of Obstetrics and Gynecology,First Metallurgical Construction Company Hospital,from January to October1999,and the other relevant factors were investigated by questionnaire at the same time.The NBNB total score was described as a dependent variable and24relevant factors such as umbilical cord blood lead and meconium lead level,etc,as independent variables.Logistic regression analysis was used to ana-lyze the associated factors at P=0.10level.Results The factors selected in the Logistic regression model included:gestational age,month of taking medicine in gestational period,hemoglobin concentration,pregnant womans psychology,meconium lead level and taking medicine during gestational period.Conclusion Neonatal neurobehavioral development could be affected by many factors.Good nutrition,longer gestational age and maintaining good psychological status during pregnancy might be benefi-cial to neonatal neurobehavioral development.However,taking medicine during the gestational period and a high meconium lead level could be harmful to neonatal neurobehavioral development.

Objective To investigate the feasibility and procedures of semi-open establishment of pneumoperitoneum(SOEPP) for laparoscopic surgery in patients with a history of abdominal surgery. Methods 117,patients,with a history of abdominal surgery received SOEPP and were retrospectively reviewed from October 1994 to January 2002. Results Out of 117 patients,pneumoperitoneum was established successfully in 115 cases by SOEPP.The successful rate of SOEPP was 98 3%(115/117). Conclusions SOEPP is a safe and feasible method in most patients with abdominal operative history.

In order to verify the origin relations of Zhouhou Emergency and modern clinical medicine in emergency treatments,we choose Zhouhou Emergency as study object,and try to verify four treatments including artificial respiration,urethral catheterization,surgical infection and hemostasis. Through tracing back to the initiation and developing history of modern medical technique,it fixes its position in modern emergency treatments,and affirms the important roll of Chinese ancient books in promoting the techniques of modern emergency science.

Objective To evaluate the functional outcomes of the phacoemulsification(Phaco)with posterior continuous curvilinear capsulorhexis(PCCC),or with PCCC and anterior vitrectomy(AV)on after cataract.Design Meta analysis based on the reference searching.Participants A comprehensive electric search in MEDLINE,CNKI,CBMdisc,VIP information,CMCC,CCPD,SSreader,21dmedia and a manual search in related textbooks,journals,congress articles and their references in English and Chinese.Methods Strictly include and exclude the relevant articles from the resource with statistical criterion and get the needing data.Statistically analysed the data with software of Review Manager4.2.2,SPSS10.0.Heterogeneity of the included articles was tested that used to select appropriate effect model to Meta-analysis.Treatment effect was measured as odds ratio between Phaco with PCCC group and Phaco with PCCC+AV group.Change the selected effect model and calculate the fail-safe number(Nfs)to assess the sensitivity and specificity of the research.Main Outcome Measures Sensitivity,heterogeneity,the according confidence intervals(CI)and Nfs.Results Six studies were included,with a sum of 305 eyes.With the outcomes of heterogeneity test,the fixed effect model was used in both groups to calculate OR.The pooled OR of after cataract was 0.13(95%CI is 0.06-0.25).Sensitivity analysis demonstrated that no disproportionate influences of individual study.And Nfs=76.8,the result was confirmed.Conclusion Phacoemulsification with posterior continuous curvilinear capsulorhexis and anterior vitrectomy is superior to phacoemulsification with posterior continuous curvilinear capsulorhexis on preventing after cataract.
