Objective To analyze inpatient expenses of percutaneous coronary intervention (PCI) and factors in the department of cardiology of a hospital, in order to provide references for setting the upper expenses limit and keeping expenses within a reasonable control Methods The hospitalization expenses data were collected from inpatients having intracoronary stenting operations in a class 3 grade A hospital in Shanghai from 2004-2006. The study made multi-factor analysis on factors possibly affecting the expenses, and built a model to predict the expense per disease, and estimated the upper limit for medical insurance expense control. These figures were used in an expense appraisal for inpatients from January to June in 2007. Results For the expenses of the 1296 PCI inpatients investigated, the largest share, 84.11%, comes from operation materials. Factors affecting the expenses, as listed by their influence, were in turn the number of stents used, length of stay, age, the status at admission, and rescues made. The study found that the average hospitalization expenses of inpatients from January to June in 2007 fell below the middle control line, and 85% of them lower than the upper control line. Conclusions To lower the medical expenses for the disease, hospitals need to take measures by using less stents, less days of stay, and less medication. Control lines specified per disease can help manage and control medical treatment quality.

Objective:To investigate the reasonable approach and surgical indication for acute necrotizing pancreatitis(ANP)by analyzing the factors that affecting the mortality of ANP.Methods:One hundred and twelve patients with ANP were retrospectively divided into two groups-the dead and the survivors.Some parameters were analyzed statistically to reveal what's the reason for death.Results:The average age,sex ratio and onset of illness were similar between two groups.And the ratio of early shock,early adult respiratory distress syndrome (ARDS),high temperature,leukocytosis and high blood glucose between two groups were also similar between two groups(P＞0.05,respectively).The important factors that affecting the mortality were:①severity of pancreatic necrosis,②improper surgical approach,③incorrect surgical indication.Conclusion:The patiets with mild or moderate ANP should mainly receive conservative treatment for 48～72 hours.The early shock and ARDS should be redressed before surgical intervention.If the operation is unavoidable,the swelling pancreas should be dissected fully,which will provide sufficient drainage after operation,and duodenostomy should be performed during operation.

Objective To observe the protective effect of magnesium gluconate on myocardial apoptosis by ischemia reperfusion injury in isolated rat hearts, and study the possible mechanism. Methods The hearts of 48 Sprague-Dawely rats were isolated, linked to Lange-ndorff perfusion apparatus, and randomly divided into 3 equal groups(n = 16 each) : Control group, ischemia/reperfusion (I/R) group and magnesium gheonate group. 8 rats in each group were perfused. Control group was pedused with modified KH buffer for 110min. I/B group was perfuesd with modified KH buffer for 20 min, then exposed to iscbemia for 30 min, and then reperfused with modified KH buffer for 60 min. Magnesium gheonate group was perfumed with modified KH buffer with magnesium gluconate for 20 min, then exposed to isohemia for 30 min and then reperfused with modified KH buffer with magnesium glueonate for 60 min. Lacate dehydrogenase (LDH) and ereatine kinase (CK) in the effluent liquid from the heart were measured after reperfusion. The concentration of Ca2+ and NO in the left ventricle were determined. The other 8 rats in each group were reperfused for 120 minutes as the method described before. After repeffusion, the myoeyte apoptosis was examined by Annexin-V-FITC/PI. After the two experiments the incidence of ventrieular arrhytlunias during reperfusion was assessed. Results Compared with I/R, magnesium glueonate decreased the incidence of ventricular an'hythmias(P <0. 01). The contents of CK and LDH in the effluent liquid from the heart in magnesium glueonate group was lower than that of I/R group (P <0. 01). The contents of Ca2+ and NO in the left ventricle in magnesium gluconate group was decreased than that of I/R group (P <0. 01). The index of myocyte apoptosis were significanfly lower in magnesium glueonate group than that of I/R group (apoptosis index :27.79±1.59 vs 33.61±2.10, P < 0. 01) . Conclusion Magnesium glueonate has protective effect on myocardial isohemia reperfusion injury in rats. The protective effect may be related to decreasing myocyte apoptosis by increasing the content of NO and relieving calcium overload.

Objective To discuss the effect of self-clotting cutter radiofrequency ablation in curing the hysteromyoma. Methods 96 patients with hysteromyoma were selected. Their hysteromyomas were cured by self-clotting cutter radiofrequency ablation through virgina under the direction of B-ultrasound. Then they were followed up for one month, three months and six months after the operation. Results Six months after the treatment,42.71% of the patients were eumenorrhea,44.79% of the patients' menstrual bleeding volumes were few, 12.5% has no change. The cure rate of anaemia was 100%. 1 month,3 months ,6 months after the treatment, the bulks of uterus and myoma were reduced,and the myoma reduced most after six months. 35.42% of the patients were cured,47.92% had remarkable effect, 15.6% had effect, 1.04% had no effect. Total effective rate was 98.72%. Conclusion The clinical effect of self-clotting cutter radiofrequency ablation in curing the hysteromyoma was satisfactory. It was a minimally invasive technique which could keep the integrality of uterus and it was rapid recovery,effective and safe,and easy to operate.

Purpose To evaluate three-dimensional strain changes of the left ventricle in patients with type 2 diabetes and poor blood glucose control using real-time three-dimensional speckle tracking imaging (RT3D-STI), and to assess the correlation between three-dimensional strains and hemoglobin A1C (HbA1c). Materials and Methods Sixty-nine patients with type 2 diabetes and forty-two control subjects were recruited in this study. The patients were divided into DM1 group (patients with well blood glucose control, HbA1c<6.5%) and DM2 group (patients with poor blood glucose control, HbA1c ≥ 6.5%) according to the glycosylated hemoglobin level. Parameters including global longitudinal strain (GLS), global circumferential strain (GCS), global radial strain (GRS), global area strain (GAS), left ventricular ejection fraction (LVEF), left ventricular end-diastolic volume (LVEDV), left ventricular end-systolic volume (LVESV) and left ventricular mass (LVM) were obtained from cardiac apex full volume images by using RT3D-STI. The parameters of three groups were compared, and the correlation between the cardiac parameters and HbA1c were analyzed. Results The GAS, GLS, GCS, GRS, LVEDV, LVESV, LVM and LVEF showed no statistic difference between DM1 group and control group (P>0.05). LVM of DM2 group was higher than that in control group (P<0.01), but GAS and GLS of DM2 group were lower than those in control group (P<0.05). LVM of DM2 group was higher than that in DM1 group (P<0.01), but GAS and GLS of DM2 group were lower than those in DM1 group (P<0.01). HbA1c was negative correlated with GAS and GLS (r= - 0.773 and 0.465, P<0.01). Conclusion The reduced GAS and GLS of the patients with type 2 diabetes and poor blood glucose control may indicate damaged myocardial function.
