Objective Probing into the rationale of DRGs payment standards for references to making DRGs payment standards.Methods Based on the DRGs grouping results of circulatory diseases cases admitted by a tertiary hospital from 2003 to 2005,two typical combinations were selected to determine the payment standard for each DRGs combination.Unnecessary medical expenses were excluded.Results According to the percentage of unnecessary medical expenses,Angina,non-special nursing,and class 1 nursing were in a group,with unnecessary medical expenses per ease of 758.00 yuan;CAG,single stent implantation,acute myocardial infaction as the main diagnose were in a group,with medical expenses per case of 2814.03 yuan;such expenses account for 6.20% of the total hospitalization expenses of both groups.Conclusions If the average expenses with unnecessary medical expenses excluded are set as the combined payment standard,hospitals will be restrained from unnecessary medical behaviors and expenses so incurred.

Transpedicular screw and rod internal fixation system is the common implants in spinal surgery. Multi-slice spiral CT and magnetic resonance imaging can generate section image, become routine imaging modality in the assessment of the postoperative spinal patients. Magnetic resonance imaging can evaluate the bone marrow and soft tissue, which is the first choice for examination. However, to the patients with metal implants, the existed metal artifacts can decrease the imaging quality. Therefore, multi-slice spiral CT is an important evaluation method for inserted material, os integumentale and anatomy. This article reviewed the production mechanism of metal-related artifacts, influencing factors and decreasing technique.

Object to define defects of drug accurately and to initially discuss its law responsibility. Method With comparative study and system thinking,we acquired few scientific recognition of drug’s defects. Result & Conclusion Defects of drug are not equal to negative drug reaction. The former one should be an unreasonable and potential risk which induces no expectant therapeutic efficacy to provide. And its law responsibility could be no-fault liability accompanied by state compensation.

Equipment department plays an important role in medical consumables management. Institutionalized management and practical medical consumable purchase are key to medical consumables management.

OBJECTIVE:To establish the gas chromatography (GC) fingerprint for the petroleum ether part of Areca peel and provide reference for the quality evaluation. METHODS:GC was conducted to establish the fingerprint for the petroleum ether part of Areca peel from 10 different areas,the cluster analysis and similarity of fingerprint data were conducted to study the similarity of GC fingerprint of Areca peel. RESULTS:There were totally 8 common peaks. All the medicine materials had the characteristics,but there were differences among the relative peak area. CONCLUSIONS:The GC fingerprint has high importance and precision and can be used for the quality control of Areca peel.

Objective The aim of this study is to address learning curve and clinical outcomes of totally robotic atrial septal defect repair on the basis of a single - center experience.Methods 54 cases of atrial septal defect (ASD) were repaired using “da Vinic S surgical system on arrested ( group Ⅰ,54 cases) or beating heart ( group Ⅱ,40 cases) from January 2007 to December 2010.Learning curves were assessed by means of regression analysis with logarithmic curve fit.The effect of operative variables on clinical outcome was analyzed by linear by regression using the Spearman's rho coefficient.Results All cases were accomplished successfully without complications.No residual shunt was detected at intraoperative or postoperative echocardiography.Significant learning curves were noted for corss clamp time in group Ⅰ:y (min) =68.741 -8.283 (n) (x)( r2 =0.489 ; P ＜ 0.01 ) ; the operation time in group Ⅱ:y (min) =355.51 - 56.29 (n) (x) ( r2 =0.581 ; P ＜ 0.01 ).No correlation was detected between operation time,cardiopulmonary bypass time,or cross clamp time and intubation time,intensive care unit stay,or total length of stay.Conclusion The robotic atrial septal defect repair can be performed safely.The learning curves is steep and the longer cardiopulmonary bypass times,operation time or cross clamp time had no negative impact on intraoperative and postoperative outcome.

AIM: To establish the quality standard for Yanqingsong Granule (Radix P uerariae, Rhizoma Chuanxiong, Radix Paeoniae Alba, Radix Angelicae Dahuricae, et c.). METHODS: Radix Puerariae; Rhizoma Chuanxio ng; Radix Paeoniae Alba; Radix Angelicae Dahuricae. in Yanqingsong Granule were identified by TLC, and the content of puerarin was determined by HPLC. RESULTS: Radix Puerariae; Rhizoma Chuanxio ng; Radix Paeoniae Alba; Radix Angelicae Dahuricae could be identified by TLC. P uerarin showed a good linear relationship at a ran ge of 0.1716～0.8580?g,r=0.9999. The average recovery was 97.49% (RSD= 1.77% and n=6). CONCLUSION: The methods are available with a reproducibility and ca n control the quality of this granule effectively.

Objective To evaluate the application value of T cell infected with Mybacterium tuberculosis assay in diagnosis of smear and culture negative pulmonary tuberculosis .Methods In total ,145 patients with smear and culture negative pulmonary tu‐berculosis and 45 patients with non‐tuberculosis lung disease were enrolled in the study .All patients received T cell infected with Mybacterium tuberculosis test and sensitivity ,specificity ,positive predicted value ,negative predicted value of testing for the diagno‐sis of smear and culture‐negative TB patients were calculated .Results The sensitivity of specificity T cell infected with Mybacteri‐um tuberculosis assay in diagnosis of smear and culture negative pulmonary tuberculosis was 85 .5% ,the specificity was 84 .4% , positive predicted value was 94 .7% ,negative predicted value was 64 .4% .No statistical significance in age‐dependent groups(P>0 .05) .Conclusion T cell infected with Mybacterium tuberculosis assay has high positive predicted value in diagnosis of smear and culture negative pulmonary tuberculosis and is suitable for clinical auxiliary diagnosis .

Objective To investigate the pathogenic constitution of thyroid nodular diasease and it' s di-agnosis and treatment.Methods A retrospective analysis was performed on data of 576 patients accepted hospi-tal therapy with thyroid nodular diasease from January 2004 to June 2008.Results Definite diagnosis of all easeswere made by surgery biopsy or fine needle aspiration-cytology.529 eases were benign lesions, another 47 eases were malignant lesions.Condusions Ultra-sound , FNAC and frozen sections have important value in differenti-al diagnosis for the thyroid nodules, nodular goiter is most common, and which have a close relationship with thy-roid carcinoma.Regular surgical resection would reduce the recurrence of thyroid nodular diasease and avoid missed diagnosis for thyroid carcinoma.
