Objective To make a method to determine trace iron (FeⅢ)in human hair. Methods Based on the coloured reaction between XO and Fe(Ⅲ)in the medium of HAc-NaAc(pH=3.2)with the presence of OP, FeⅢ was determined by spetrophotometry. Results It was found that when pH=3.2 and in the presence of OP, iron(Ⅲ) reacted with XO to form a stationary complex. The maximum absorption wave of Fe(Ⅲ)-XO was 570 nm, as OP was added, it moved to 590 nm, and the sensitivity was increased obviously when the molar absorptivity of the complex reached 3.67?105 L/(mol?cm) from 3.04?104 L/(mol?cm), the linear range for the content of Fe(Ⅲ)was 0.0～0.8 ?g/ml(0.0～20.0 ?g/25 ml), the regression equation of calibration graph was A=0.00236+0.542c(?g/25 ml)with a correlation coefficient of 0.997 6, detection limit was 6.09?10-6 g/L, RSD=0.97% and rate of recovery was 96%-99%. Conclusion The method can be used for the determination of trace iron(Ⅲ)in human hair samples.

OObjective] To explore the version and academic achievements of“Yan Hou Lun”. [Method] Finding of the bibliography of books about the version, one by one to check. And analyse the content of the book, summarize the academic achievement.[Result] There are three versions. This book has written tonsillitis, and other common diseases of throat. Diagnosis of disease, according to the lesion site and colour and lustre. It promotes the use of external power.[Conclusion]It can be divided into two versions of the system. It is a throat book appearing earlier, has a certain clinical practicability.

Objective To explore the clinical curative effect of central venous catheter drainage in treating pleural effusion.Methods 100 cases with pleural effusion were treated by the central venous catheter drainage.The curative effect,complications and adverse reactions were observed.Results Ater treatment for 12 ～ 28d,catheter drainage of 100 patients were all successful at the first time.The clinical effect:completely relieve 40 cases(40.0％),clinical partial remission 47 cases(47.0％),inefficient 13 cases (13.0％),and the total effective rate was 87.0％.There were some complications:pneumothorax 1 case,hemorrhage 2 cases,infection 1 case,pleural reaction 3 cases,pain 3 cases,subcutaneous emphysema 2 cases and take off the tube 1 case,the incidence rate of complications was 13.0％.Conclusion Central venous catheter drainage in t.reating pleural effusion has significant curative effect,which is worthy of clinical application.

Objective:To investigate the relationship between microalbuminuria(MAU)and obesity in Chongqing natives.Methods: Four hundred and seventy eight subjects over 30 years old were selected at random from health examination population.They were divided into 3 groups according to the Body Mass Index(BMI)diagnostic standard of〈The Guide of control and prevention of overweight and obesity in Chinese aduhs〉,control group(Con group),over weight group(Ow group)and obesity group(Oh group).MAU were tested in all groups and invested with every item in Ob group.Results:The prevalences of over weight and obesity in the present study were 40.0% and 7.3% respectively.The MAU in Ob group was more than that in Con group (P

ObjectiveTo explore the theoretical construct of network values and design the network values questionnaire.MethodsThis research was to design the network values questionnaire based on an open-ended inventory survey,overviews of former studies and counseling of experts.Through stratified sampling,832 college students were investigated by the network questionnaire.The data were examined by item analysis,factor analysis,reliability and validity analysis.ResultsThe network values was a multi-dimensional construct which had three factors.The three factors cumulative total explained variance was 50.719％,52.545％ and 50.510％.The questionnaire's internal consistency reliability was 0.931 and 0.809-0.874 for the three subscales.The questionnaire's split-half reliability was 0.902 and 0.772-0.864 for the three subscales.ConclusionThe theoretical construct of network values is rational.The questionnaire has good reliability and validity.

The establishment of cerebral collateral circulation is a secondary compensatory mechanism after cerebral ischemia.The expression of endogenous angiogenic growth factors is up regulated,angiogenesis and arteriogenesis are initiated,and the establishment of collateral circulation is accelerated after cerebral ischemia.Some drugs may promote the establishment of collateral circulation after ischemic stroke and improve the prognosis of patients.

Objective To use puncture and consultation system for improving the needle puncture success rate of pediatric nurses, upgrading the level of puncture technology, reducing patient complaints and increasing patient satisfaction. Methods 200 pediatric patients selected from March,2006 to March, 2010 were divided into the intervention group and the control group, The intervention group adopted puncture and consultation system while the control group did not. The success rate of puncture, patients complaints and patients satisfaction were compared. Results The puncture success rate of pediatric nurses increased,and patients' complaints reduced and patients' satisfaction degree increased in the intervention group compared with that of the control group. Conclusions The pediatric puncture and consultation system in the tertiary hospital not only increases the satisfaction degree of pediatric patients' parents, but also improves the level of puncture technique of pediatric nurses, and has important social effect outside hospital.

Multiple myeloma (MM) is a genetically complex disease that is becoming more common in today' s aging population.In the 18th European Hematology Association (EHA) annual meeting,there were a number of key topics focusing on the development of MM from intraclonal heterogeneity,novel therapeutic agents,and relapse and refractory MM therapy,etc.

Automated body fluid cytology analysis has been accepted by clinical laboratories gradually.The improvement of efficacy and analytical precision can overcome some defects of traditional manual method,such as time-consuming and poor repeatability.To make use of the advantages of automated fluid cell analysis technology,the automated method and microscopic method must be combined by setting review rules.Meanwhile,more attentions must be paied to sample collection and specimen preservation at pre-analytical stage,verification of instrument performance at analytical stage and necessary clinical communication at post-analytical stage.Only if a complete system of quality management,standardization of procedures,result validation and interpretation is implemented in the routine work,the clinical significance of body fluid cytological analysis can be recognized in clinical practice.
