Objective: To investigate the applicative value of multislice spiral computed tomography angiography (MSCTA) in the microsurgery of ruptured intracranial aneurysm caused acute intracerebral hematoma. Methods: The imaging and clinical data of 15 patients with ruptured intracranial aneurysm caused intracerebral hematomas, whom underwent emergency surgery after preoperative CT angiography (CTA) were analyzed retrospectively. The surgical plan was determined according to the CTA imaging results. The hematomas were evacuated and the aneurysm were clipped. The applicative value of CTA were evaluated. Results: All the 15 patients were confirmed as intracranial aneurysms in the operation, which was essentially consistent with the preoperative diagnosis by CTA. The size and growth direction of the aneurysms were essentially consistent with the preoperative judgement, and all the aneurysms were clipped. The prognosis of the patients was assessed by the Glasgow Outcome Scale (GOS). All the patients were followed up by the outpatient department and/or telephone for 6 to 78 months (mean 24 months). The GOS score in 2 patients was 2, in 2 was 3, in 6 was 4, and in 5 was 5. Conclusion: Head CTA can briefly and quickly identify the ruptured intracranial aneurysm caused intracerebral hematoma and provide intuitive three-dimensional morphology and anatomical localization of the aneurysms. It is helpful to hematoma evacuation and clipping of the aneurysms in emergency operation.

OBJECTIVETo observe thee efficacy of different ways of percutaneous coronary intervention (PCI) for treating elderly coronary heart disease (CHD) patients.

METHODSTotally 470 elderly CHD patients were classified to three age brackets (equal to or more than 85 years old, 60 to 74 years old, 75 to 84 years old). They were assigned to the transradial intervention (TRI) group (236 cases) and the transfemoral intervention (TFI) group (234 cases) according to different intervention pathways. Correlated indices and postoperative clinical efficacy were compared between the two groups.

RESULTSA higher successful rate of surgery was obviously got in patients 85 years old or older than 85 than in those 60 to 74 years old and 75 to 84 years old (P <0. 05). The incidence of major cardiovascular events (MACE) was reduced at post-operative 12 and 24 months in patients 85 years old or older than 85 (P <0. 05). The case number for changing intervention pathway were increased in the TRI group with statistical difference (P <0. 05). Compared with the TFI group, the case number for changing intervention pathway was increased; the time for arteriopuncture, the time for catheterization, and the time for X-ray exposure were prolonged; the time for postoperative bedding were obviously shortened; the incidence of vascular complications at the puncture site were lowered. The incidence of postoperative 12-month MACE was lowered, all with statistical difference (all P <0. 05). The incidence of MACE within postoperative 24-month MACE decreased in patients 60 to 74 years old and 75 to 84 years old (P <0. 05). The incidence of MACE within postoperative 24 months increased in patients 85 years old or older than 85 of the TRI group with statistical difference (P <0. 05).

CONCLUSIONTRI can be preferably chosen for PC in treating elderly CHD patients.

Objective To study the value of iron metabolism indicatorsin thalassemia .Methods 218 cases of thalassemia ,57 ca‐ses of iron deficiency anemia (IDA) children and 70 healthy children(control group) were enrolled in the study ,and serum iron (SI) ,total iron binding capacity(TIBC) ,transferrin(Tf) ,serum ferritin (SF) were detected for them .Results β‐thalassemia double heterozygous(β0 ) or homozygous group :SI levels were significantly higher than the other groups(P<0 .05) ,while TIBC ,Tf levels were significantly lower than the other groups(P<0 .05);α‐thalassemia group (static α‐thalassemia ,standard α‐thalassemia):SI , TIBC levels compared with control group showed no significant difference(P>0 .05) ,but Tf level was higher than control group(P<0 .05);hemoglobin H disease group:when TIBC ,Tf levels compared with the control group ,the difference was statistically signif‐icant(P<0 .05) ,when SI compared with the control group ,the difference was not statistically significant(P>0 .05) .Conclusion Compared with Tf ,SI and TIBC are better indicators for monitoring iron loading in children with thalassemia .The increased SI level and decreased TIBC level are two indicators for the diagnosis of β0 thalassemia in children with cellule anaemia .

Objective To investigate the principle and method of breast-concerving therapy of early-stage breast cancer.Methods The clinical data of 31 cases of early-stage breast cancer who were conserved breast were analysed retrospectively from January 1992 to April 2002. 14 cases performed wide lumpectomy plus axillary nodes dissection,5 cases performed wide lumpectomy, 11 cases performed lumpectomy and 1 case did not perform operation. After operation 17 cases received radiotherapy and chemotherapy,8 cases received only radiotherapy,3 cases received only chemotherapy and 3 cases did not receive radio-chemotherapy.Results Surviving time of all patients was 6 to 122 months.Mean surviving time was 32?5 months.Median of survival time was 22 months.Among 31 patients 1 case died of metastasis due to refusing chemotherapy,the other were alive now and 10 cases of all patients have survival over 3 years. Local recurrence was found in 1 case after 5 years,but he did not take chemotherapy and radiotherapy. Fairly good cosmetic outcome was obtained in 29 patients(93 5%).Conclusions It probably is ideal method that the wide lumpectomy plus axillary nodes dissection combines rationally with radiotherapy and chemotherapy in breast-conserving treatment of early- stage breast cancer.

OBJECTIVE: To analyze the prevalence of bacterial infection and drug sensitivity after liver transplantation so as to provide reference to effective clinical therapy. METHODS: A retrospective survey of 113 patients who underwent orthotopic liver transplantation was carried out. RESULTS: The reported total incidence of bacterial infection after liver transplantation was 45.1%, while the verified incidence was 28.3%. The major bacterials were Klebsiella pneumoniae and Enterococcus faecom. Multidrug-resistant was observed. CONCLUSION: It is very important to prevent bacterial infection and use antibiotic rationaly. Selection of effective antibiotics according to etiologic data and resistance of bacterial can help prevent the occurance of drug resistant strains.

Objective To explore the differences in behavior of anxiety individuals and the normal control under different feedback (positive feedback,negative feedback).Methods 400 university students were investigated using self-rating anxiety scale(SAS) and state anxiety inventory (SAI) and the data were analyzed with balloon analogue risk task.Results The score of anxiety group(24.28±6.12) was significantly lower (t=-2.25,P＜0.05) than that of control group(29.80±7.26) in the number of busting balloons.But in the number of busting balloons of positive and negative feedback condition,scores of anxiety group and control group were not significantly different(t=-1.82,P＞0.05;t=-1.78,P＞0.05).Conclusions Influence of anxiety on decision-making often manifests as risk aversion.

Conclusion At current stage, public hospitals need pay more attention to material interests claims of employees.

Twenty-seven cases of simple type 2 diabetes mellitus,30 cases of coronary heart disease,and 32 cases of type 2 diabetes with coronary heart disease were enrolled in this study according to the results of coronary angiography.Meanwhile,32 healthy subjects were taken as a control group.The serum matrix metalloproteinase-9 (MMP-9) and other clinical and laboratory parameters were determined.The results showed that serum MMP-9 may play a minor role in the progression of coronary heart disease in type 2 diabetic patients.

Objective To study spiral CT features and pathological basis of nodular goiter ,so that to improve the diagnostic accuracy of nodular goiter.Methods CT findings in 34 patients with nodular goiter confirmed by pathology were retrospectively analyzed and compared with pathological findings. Results Thyroid density in the patients with NG was lower than that in the normal. There was no statistically significant difference in the density between single and multi-NG. Most lesions(28/34) were multiple, round or oval, with different size and smooth edges. The density of majority lesions was lower than nearby normal tissue. Most lesions (27/34) were uniform in density. Central necrosis(5/34)often appeared in the bigger lesions(diameter＞3.0 cm). The CT value of the lesions was increased (47.1±42.2) HU after enhancement,but lower than surrounding thyroid tissue. Calcifications in the lesions(6/34)were puncticular,plaque or crustiform. Single or multiple cystic-solid or solid nodules could be seen in pathology, without a continuous capsule in the majority. Some patients (5/13) with single NG shown on imaging study were multi-NG in the pathology. Three cases of diffuse NG showed by CT were malignant in pathology. Conclusion There are certain characteristics for NG on spiral CT. Comprehensive evaluation may improve the accuracy of CT diagnosis.
