A satisfaction survey carried out by Beijing Chao-Yang Hospital during the Beijing 2008 Olympic Games, found differences of patient satisfaction between locals and overseas patients in consulting environment, outpatient procedure, quality of service, quality of diagnosis and treatment. The patient satisfaction of overseas patients was lower than locals. Especially noteworthy is the low satisfaction of the former for the hospital coloring, privacy in the sector, registration, vocal communication, patient condition statement, nurse attitude and service quality. Real-time improvement in these aspects of medical services has harvested obvious progress. Results of the satisfaction survey provided valuable reference materials for large-scale activities, and ongoing improvement of medical services in the long run.

OBJECTIVE: To observe the changes of malondialdehyde (MDA), superoxide dismutase (SOD), tumor necrosis factor-alpha (TNF-alpha), and interleukin-1beta (IL-1beta) in rat brain tissue and to explore the mechanism of secondary cerebral injury after brain concussion. METHODS: The brain concussion model was established with the pathological changes of rat brain tissue by Weil stain. The expressions of MDA and SOD in brain tissue were examined by photochemical method. The expressions of TNF-alpha and IL-1beta in cerebral cortex and hippocampus were examined by immunochemistry. RESULTS: Nerve myelin sheath showed disorder, disruption, gryposis and swelling by Weil stain. Above changes were more severe at 12h. The quantity of MDA in rat brain tissue after concussion was significantly higher than that in the control group. The activity of SOD was significantly lower than that in the control group. The expressions of TNF-alpha and IL-1beta increased more significantly in cerebral cortex and hippocampus in rat brain tissue after concussion than that in the control group. CONCLUSION Oxidative stress and inflammatory injury in the rat brain tissue, which may play an important role in secondary cerebral injury after concussion.

Objective To study the value of lung window and soft tissue window in measuring colon diseases with experimental CTVC examination.Methods Twenty-four artificial polypoid diseases were placed with glue in a thoroughly cleaned porcine colon(overall length,150 era)that was distented with air and submerged in a water phantom and scanned 10 times on a 64-MSCT(GE Light speed)with identical scanning parameters.The data were reconstructed every 0.625 mm and reviewed using 2D images, navigation,MPR and 3D volume-rendered images on a GE AW 4.2 workstation.The maximum diameters of the artificial polypoids were measured by two radiologists with more than 10 years working experience in lung window(W = 1000,L =-700)and soft tissue window(W =400,L =40),respectively.The average value of maximum diameters of the artificial polypoids were measured for 10 times and were compared with the actual diameter.Results Twenty-four artificial polypoid diseases and their shape,size,loeation and relation of diseases with bowel wall were all showed excellently.The maximum diameter measured was close to the actual diameter.The average value was mostly less than actual diameter and a few of them more than the actual diameter.The maximum diameter measured in lung window was close to the actual diameter,and there was no difference between the two data sets(t =0.431,P =0.669).There was difference between the maximum diameter measured in soft tissue window and the virtual diameter(t = 2.691,P = 0.010). Conclusion In screening the colon diseases,CTVC is a good method of choice with no insult or less insult, and higher repeatability.The lung window should be chosen in measuring colon diseases in CTVC examination.

Objective To investigate the curative effect of granulated cancellous bone autograft in treatment of refractory bone nonunion after limited contouring of bone ends. Methods Between 2003 and 2006, 13 patients with refractory bone nonunion were treated with external fixation and granulated cancellous bone autograft after limited contouring of bone ends. Results The mean follow-up period was 22.6 months (19-30 months), which showed that all patients gained bone union and resumed com-plete weight loading or previous job at final follow-up. The mean fixation time of external fixators was 10.6 months (7-18 months). The intermittent or persistent pin-track infection occurred in eight patients and relieved by pin-track care and oral or parenteral antibiotics, with no infection after removing external fixator. Conclusion The granulated cancellous bone autograft after limited contouring of bone ends is an effective method for treatment of refractory bone nonunion.

ObjectiveTo study the expression changes of peripheral blood monocyte human leukocyte antigen DR (HLA-DR) in patients with severe craniocerebral injury,and investigate the correlation between HLA-DR expression and infection and prognosis.MethodsNinety patients with craniocerebral injury were selected as experimental group and were divided according to the Glasgow coma scale (GCS) score after hospitalization into experimental group 1 (GCS score 13-15 scores ),experimental group 2 (GCS score 9-12 scores) and experimental group 3 (GCS score 3-8 scores) with 30 patients each,which were moderate,medium,severe craniocerebral injury,respectively.Thirty healthy people were chosen at the same period as control group.The HLA-DR expression of experimental group was detected after 1,3,7 and 14 d of admission by flow cytometry,and the HLA-DR expression of control group was detected on the day they got physical examination.The rates of infection,cure,disability,vegetative state and mortality were counted after 30 d of admission.ResultsThe HLA-DR expressions in experimental group 1 and experimental group 2 after 1,3,7,14 d of admission were (28.11 ± 2.37),(26.45 ± 1.63),(27.75 ± 1.83),(27.15 ± 2.17) MCF and (29.34 ±2.07),(27.55 ± 1.63),(28.42 ± 1.94),(29.46 ±2.12) MCF,which had no statistical difference compared with that in control group [(29.18 ± 1.91 ) MCF](P＞ 0.05).The HLA-DR expressions in experimental group 1 and experimental group 2 after 1,3,7 d of admission and control group had statistical differences compared with those in experimental group 3 after 1,3,7 d of admission [(18.02 ± 1.78),(16.05 ± 1.97 ),(20.76 ± 1.65) MCF ] (P ＜ 0.05).The HLA-DR expressions in experimental group 1 and experimental group 2 after 14 d of admission and control group had no statistical significance compared with that in experimental group 3 after 14 d of admission [ (26.13 ± 2.15) MCF](P＞ 0.05).The infection rates of experimental group 1,experimental group 2 and experimental group 3 were 0,3.6％(1/28),82.8％(24/29),respectively,while the cure rates were 100.0％ (30/30),100.0％ (28/28),10.3％ (3/29),the disability rates were 0,0,41.4％ (12/29),the vegetative state rates were 0,0,20.7％ (6/29),and the mortality were 0,0,27.6％ (8/29).There was no statistical significance in the rates of infection,cure,disability,vegetative state and mortality between experimental group 1 and experimental group 2 (P＞ 0.05 ).While there was statistical differences in the rates of infection,cure,disability,vegetative state and mortality among experimental group 1,experimental group 2 and experimental group 3 (P ＜ 0.05).ConclusionsThe HLA-DR expression changes of patients with moderate and medium craniocerebral injury after 1,3,7,14 d of admission are not significant.The HLA-DR expression of patients with severe craniocerebral injury begins to decline from 1 d after injury,declines obviously at 3 d,increases from 7 d,returns to normal level at 14 d.The decline of HLA-DR expression in patients with severe craniocerebral injury is correlated with the infection,and predicts poor prognosis.

ObjectiveTo study the impact of primary PCI in culprit artery on epicardial blood flow of nonculprit artery in patients with STEMI. MethodsEnrolled 117 patients with anterior wall STEMI were treated with primary PCI in the culprit artery, left anterior descending artery (LAD, as study group.Another 100 patients with normal coronary artery evidenced by angiography were enrolled as control group.The differences in CTFC (corrected TIMI frame count measured by using digital subtraction arteriography,TIMI =thrombolysis in myocardial infarction) and MBG (myocardium blood flow perfusion grading)between pre and post primary PCI in both culprit artery and nonculprit artery ( left circumflex artery, LCX),and CTFC and MBG were also detected in the subjects of control group. Blood samples were collected and the levels of CRP (C-reactive protein) were assayed. Clinical and angiographic features were analyzed.ResultsThe CTFC of nonculprit artery (LCX) and the level of MBG in patients with anterior wall STEMI were different from the level of MBG and CTFC in control group ( P＜0. 05) before primary PCI. The level of MBG and CTFC in nonculprit artery (LCX) were improved (P ＜ 0. 05 ) after primary PCI, but they did not resume to normal level. Patients without reflow in culprit artery had higher incidence of no reflow in nonculprit artery than patients with re-flow (78％ vs. 8％, P ＜ 0. 01 ), and the level of CRP in patients without reflow in nonculprit artery were higher than those in patients with re-flow ( P ＜ 0. 05). Conclusions The perfusion of nonculprit artery may be impaired in patients with STEMI. Although the perfusion of nonculprit artery may be improved after primary PCI in culprit artery, but it was still lower than those in the control group, and inflammation mechanism might contribute to it.

Objective To investigate the effect of microcireulation blood flow and altering immunity by Chuanxiongqin,ulinastain and thymosin α1 on sepsis patients.Methods 90 patients were randomly divided into 3 groups(n=30),namely ICU group,Chuanxiongqin group,ulinastain and thymosin α1 group.HLA-DR/CD14+and IL-6,TNF-α,Lac,DD were measured.Results (1)DD showed no significant difference at every time point between ICU group and ulinastain+thymosin α1 group(P＞0.05).DD decreased in Chuanxiongqin group,and was significantly different from the others on the third day.(2)Lac unchanged significantly at every time point in ICU group(P＞0.05).Lac in Chuanxiongqin group and ulinastain+thymeain α1 group tended to decrease,and was statistically different from ICU group on the second day.(3)IL-6 and TNF-α tended to increase at every time point in ICU group(P＜0.05).In ulinastain+thymosin α1 group,IL-6 and TNF-α returned to the level before treatment,HLA-DR/(D14+increased significantly,and was higher than Chuanxiongqin group and ICU group statistically.Conclusion Chuanxiongqin could ameliorate circulation;ulinastsin and thymosin α1 could depress IL-6,TNF-α.So ulinastain and thymosin α1 might protect the immunity of sepsis patients.

Objective To prospectively explore the techniques and correction results of the method of vertebral coplanar alignment (VCA) in posterior correction for thoracic scoliosis. Methods Between June 2008 to March 2009, 27 patients with idiopathic thoracic scoliosis were selected to undergo posterior pedicle screw fixation with assistance of Coplanar system. There were 26 females and 1 male with the average age of 15.9 years(ranged 11-23 years). There were type 1 in 25 cases and type 2 in two cases. The levels of fusion were established according to the Lenke criteria. The average preoperative coronal Cobb angle was 49°(ranged 40°-70° ). During the procedure, the pedicle screws were inserted in each involved levels on the convex side, an extended Coplanar tube was screwed in line with screw axis to each screws. Then two rigid bars were inserted through the uppermost part of the slotted tube sequentially. As the bar was gently driven down toward the bottom end, the pedicle screws axis started to converge in the straight line, correcting translation and rotation. Spacers were inserted into the slots of the tubes to achieve the ideal physiologic thoracic kyphosis. Once the rod was fixated in the concave side of the main curve, the Coplanar system could be removed. Results The mean postoperative Cobb angle was 14° (ranged 6°-25°), representing the correction rate of 70.7%. The average duration of surgery was 245 min (ranged 210-300 min) and a mean estimated blood loss was 1500 ml (ranged 600-2100 ml). The duration of follow-up averaged 15 (12-18) months. The loss of correction at last follow-up was 3° with the loss of correction rate of 6.1%. In the sagittal plane, the thoracic kyphosis was restored from 18° to 25°. No coronal or sagittal plane decompensation occurred. No thoraeoplasties were necessary to correct the residual rib hump. There was no death, infection and neurological complications. Conclusion The Coplanar is a new technique for the correction of scoliosis, its advantage lies in excellent and modulatable three-dimensional correction with a single and standardized maneuver.
