A total of 56 printing and record medium production enterprises were selected as the study subjects by judgmental sampling method to analyze the worksite Results survey of occupational health and the key occupational hazard factors. There were 256 organic solvent samples ， detected in 56 enterprises which included a total of 148 terms and 1 358 categories of volatile constituents. The top three （ ）， - （ ） （ ） volatile constituents were toluene 35.5% n hexane 25.7% and methanol 23.8% . The top three detected samples of the （ ， ， ， ， - ， ，- ， eight key chemical occupational hazard factors benzene toluene xylene ethylbenzene n hexane 1 2 dichloroethane ） ， - ， trichloroethylene and chloroform were toluene n hexane and ethylbenzene. In the workplace air toluene was the most risk ， factor of occupational hazard factors in enterprise and in sample detection while no trichloromethane was detected. The toluene in workplace air was found to exceed the national standard with the rate of 2.6%. It showed that 27.9% of the work sites were found occupational noise hazard which was over national standard in the 10 key work sites. Only 64.3% and 57.1% enterprises - performed occupational hazard factors detection and occupational health examination. Both none or invalid toxicant proof - facilities accounted for 33.9% of the enterprises. Both none or invalid noise proof facilities accounted for 78.6% of the Conclusion ， - enterprises. The occupational hazards factor of toluene n hexane and noise were serious in printing and record ， medium production enterprises in Longgang District of Shenzhen City and the occupational health management was imperfect. The occupational regulation should be enhanced in this industry.

Rehabilitation is very important to the therapeutic effect of total knee arthroplasty, and it's also the key measure for the knee function to reach the expected effect after the surgery. The most important contents of rehabilitation therapies are the training of muscle strength, range of joint motion, joint position sense and gait. Integrated rehabilitation therapies was used to improve the knee function as possible, such as all kinds of training to improve the knee muscle strength of flex and extend; early training of continued positive motion of knee joint to improve the knee range of motion; the training of knee joint position sense to improve the ability of motion control, posture adjusting and balance keeping; the gait training to adjust the unusual gait.

Objective To analyze the amount and allocation of pediatric healthcare resources in Chengdu,and to recommend on local pediatric healthcare resources shortages.Methods Pediatric healthcare resources data of Chengdu came from pediatric relevant data reported regularly at yearend by the counties and districts to healthcare administration of the city.Data from such reports were subject to statistics with various indexes and descriptive analysis.Analyzed in focus was the distribution in 2015 of pediatric healthcare resources of the city among medical institutions of various types,levels and properties,as well as causes for such shortage.Results Tertiary hospitals hold 62.3% of the pediatric beds and 64.2% of pediatricians,and provide around 70% of the medical workload for pediatric outpatients and inpatients,upon the majority of pediatricians with master degree and above,and senior ones of/above associate chief physician titles;Tertiary hospitals have 58.7% of the pediatric beds and 49.7% of pediatricians,yet the outpatients served by specialized hospitals were 5% above tertiary hospitals.Conclusions The imbalance and shortage in total of pediatric resources in Chengdu result from stable source of manpower supply,high professional risk exposure,low income,and long training duration among others.Such measures as a better pediatrician development system,greater incentives for pediatric development,and enhanced development pediatric service consortiums,as well as greater support for private specialized pediatric hospitals.Those measures combined can effectively alleviate the shortage of pediatric resources.

The survey aims at probing into the current development of medical instruments in hospitals and computerized quality control,upgrading the competence of hospital engineering departments and guiding the development of medical clinical engineering.Questionnaire surveys were made to the medical engineering departments of 195 hospitals above secondary hospitals in Zhejiang,totaling 1001 professionals.The results indicate significant differences among hospitals of various scales in terms of deployment of medical engineering Professionals,working conditions,and computerized applications,yet a consistency in academic title promotion and training requirements.In this consideration,it is imperative to build the team,maintain consistency in professional certification of medical engineering professionals,build a regular and systematic examination,promotion and certification system,enhance training in professional knowledge and equipment quality control,as well as promoting information and resources sharing.All these efforts are essential for better quality control and management of medical engineering departments,and promoting computerized management of medical instruments.

Objective To evaluate the diagnostic evaluation of isotropic scanning and Lung Care soft- ware in solitary pulmonary nodules,and to improve the diagnostic accuracy.Methods 52 patients suffered from SPN were included in our study.Two experts in CT analyzed the films.First,they read the axial images and made diagnosis.Then isotropic scanning and lung care software approaches were used on 16 spiral CT and another analysis were made again.The results were compared with pathological diagnosis respectively. Results Spiculated sign,lobulated sign,vessel convergence were found more on isotropic scanning approach, that had significant difference with axial images analysis(P

Objective To observe the effects of standardized three stage rehabilitation treatment on the neu- rological deficit scores (NDS) and ADL performance of ischemic stroke patients.Methods A total of 164 ischemic stroke patients were recruited and randomly divided into a rehabilitation group and a control group.The neurological function and ADL performance of the patients were assessed by using NDS and Modified Barthcl Index (MBI) at the admission,at the end of 1st,3rd and 6th months post stroke.Results No significant differences were found be- tween the rehabilitative and the control groups with regard to NDS and MBI at admission.The NDS demonstrated a decreasing tendency,while the MBI score an increasing tendency in both groups.In the control group,significant difference of NDS was found between admission and the end of 1st month as well as between the end of the 1 st and the 3rd months.In rehabilitation group,significant difference was revealed between all the time points with regard to NDS and MBI scores.At the end of the 1st,3rd and 6th months,the MBI scores of the rehabilitation group were signifi- cantly higher than those of the control group,indicating that the ADL performance of those treated with standardized three-stage rehabilitation protocol was improved quicker than those without the protocol.Conclusion Standardized three-stage rehabilitation treatment could improve the neurological function and ADL performance of the ischemic stroke patients.

Objective To explore the clinical application and safety of treatment of percutaneous radioactive 125I seed implantation treatment in lung metastases under CT guidance.Methods Twenty-seven lung metastatic malignancy cases (67 nodules) were studied.Eighteen cases (46 nodules) were hepatic cancer,4 cases (9 nodules) were prostate cancer,and 5 cases (12 nodules) were breast carcinoma.Diameters of lung nodules ranged from 0.5 cm to 4.0 cm with an average diameter of 2.1 cm.125I seeds were embedded under CT guidance,using 2 to 33 particles/nodule with an activity of 18.5 to 29.6 MBq/grain for each particle.Tumor matched peripheral dose was 90-120 Gy.Postoperative validation and quality evaluation followed.Results Four months later,24 nodules showed CR,30 showed PR,5 showed NC and 8 showed PD.The total effective rate was 80.6％ (54/67).In the course of treatment,11 patients had pneumothorax,3 had heavy lung compression and 4 had hemoptysis.All conditions were improved by pleural puncture or under close follow-up observation.Conclusion 125I seed implantation is an effective and safe technique in treatment of metastatic lung tumors under CT guidance.
