OBJECTIVE To investigate the risk factors,characteristics,measures of prevention and treatment of hospital fungal infection among maintenance hemodialysis patients.METHODS Clinical data of 128 maintenance hemodialysis patients between Jan 2002 and Dec 2006 were enrolled in this retrospective study of hospitalized infection cases.RESULTS During above period,36 infection episodes of 27 cases were occurred.The major infection site was lungs(69.4%).the Candida albicans was the main pathogen species(61.1%).The underlying and complicating diseases such as diabetes,chronic obstructive pulmonary disease and tumor,long antibiotics using,long hospitalization,poor nutrition status,inadequate hemodialysis,and venous indwelling catheter were the risk factors which led to fungal infection among maintenance hemodialysis patients.CONCLUSIONS The maintenance hemodialysis patients are easy to induce fungal infection.The C.albicans is the main pathogen species.The incidence of underlying diseases is rather high.Treatment of original diseases and complicating diseases,the standard using of antibiotics,adequate hemodialysis,the nutrition status and the reduction of the indwelling time of venous catheter are all the keys to decrease the fungal infection.

Objective To evaluate the effect of sevoflurane on left ventricular function in patients undergoing elective coronary artery bypass grafting (CABG) .Methods Thirty-five ASA Ⅱ or Ⅲ patients of both sexes (30 males, 5 females) aged 53-75 yr weighing 46-100 kg undergoing CABG were enrolled in this study. Transesophageal echocardiography (TEE) probe was placed. The TEE variables including cardiac index (CI), left ventricular short axis shortening (FS), left ventricular ejection fraction (LVEF), low propagation velocity ( Vp), E wave velocity (E) , A wave velocity ( A) , systolic wave velocity ( S) , diastolic wave velocity ( D), AR wave velocity, E/A ratio and S/D ratio were recorded before inhalation of sevoflurane (T_1 ) , and 5 min (T_2) and 15 rain ( T_3) after inhalation of sevoflurane after splitting of sternum, and before inhalation of sevoflurane (T_4 ), 5 min (T_5) and 15 min (T_6) after inhalation of sevoflurane after the closure of sternum. The end-tidal concentration of sevoflurane corresponded to 1 MAC. Anesthesia was induced with midazolam 0.05 nig/kg, sufentanil 0.5μg/kg and rocuronium 0.9 mg/kg and maintained with infusion of propofol at 4-6 mg·kg~(-1) ·h~(-1), remifentanil at 0.2-0.4μgkg~(-1)·h~(-1) and atracurium at 0.5 mg·kg~(-1)·h~(-1). The patients were mechanically ventilated after tracheal intubation (V_T 8 ml/kg, RR 12 bpm, I:E 1:2, FiO_2 70%-80% ) .Results (1) MAP and CI were significantly decreased at 5 and 15 min after sevoflurane inhalation. LVEF and FS were also decreased. (2) There was no significant change in diastolic function indexes after sevoflurane inhalation including E and A wave velocity, systolic wave velocity, diastolic wave velocity, E/A ratio and S/D ratio. (3) Cardiac function improved after CABG. CI, LVEF and FS were significantly increased after CABG as compared with preoperative values. Conclusion In patients undergoing elective CABG, sevoflurane (the end-tidal concentration corresponding to 1 MAC) can depress left ventricular systolic function but does not affect left ventricular diastolic function.

[Objective]To summarize the experiences of total hip replacement with cementless joint components in the treatment of osteoarthritis secondary to acetabular dysplasia in adults and to evaluate its early effect. [Method]From March 2000 to March 2007, thirty hips in 25 adult patients with osteoarthritis secondary to acetabular dysplasia undergoing total hip replacement with cementless joint components were included in this study. Of the patients, 5 were male and 20 were female.Their ages ranged from 35 to 55 years with an average age of 55 years. The patients mainly complained of pain and claudication. According to the Hartofilakidis classification , Semi-dislocation occurred in 21 hips and high-dislocation in 9 hips.Five patients underwent bilateral total hip replacements and twenty patients had unilateral total hip replacement.[Result]The duration of follow-up ranged from 8 months to 7 years ( average 3 years and 9 months ) . The average Harris score was increased from 36.09 to 88.21 points, They could take care of themselves and returned to their previous job. All the patients were pain-free and there was no sign of aseptic looseing or subsidence.[Conclusion]Total hip replacement with cementless joint components is an effective method for the treatment of osteoarthritis secondray to acetabular dysplasia in adults.The key point to the success for operation are appropriate cementless joint components, deepened medial wall of the acetabulum and improved the techniques of bone graft in the true acetabulum.

Backgroud Numerous studies have confirmed the effectiveness of slowing the progression of atherosclerosis by blood pressure (Bp)control in patients with hypertension and several studies also showed the efficacy of intensive glycemic control in decreasing progression of carotid intima-media thickness (CIMT) in patients with type 1 and type 2 diabetes. However, few studies have compared the relative importance of glycemic vs. Bp control in patients with diabetes and hypertension. We aimed to investigate the association between Bp and glycemic control and subclinical carotid atherosclerosis in older patients with hypertension and type 2 diabetes. Methods In a cross-sectional study, B-mode high-resolution ultrasonography of the carotid artery was performed in 670 subjects (508 males and 162 females) aged 60 years or over who had self-reported hypertension and diabetes but no history of coronary heart disease or stroke. Subjects were categorized by their systolic blood pressure: tight control, < 130 mmHg; usual control, 130-139 mmHg; or uncontrolled, > 140 mmHg, and by their hemoglobin Alc (HbAlc) level: tight control, < 6.5%; usual control, 6.5%-7.5%; or uncontrolled, > 7.5%, respectively. Results The mean CIMT was 8.20±0.11 mm, and carotid plaque was found in 52.5% (352/670) subjects. Overall, 62.1% of the subjects had subclinical carotid atherosclerosis, defined as having either carotid plaque or elevated CIMT (≥ 1.1 mm). The mean CIMT was significantly different between Bp control categories (7.60 ± 0.09 mm, 7.90 ± 0.08 mm, and 8.60±0.12 nun, respectively, P = 0.03) but not between glycemic control categories (8.20 ± 0.10 ram, 8.1 ± 0.08 mm, and 8.40 ± 0.14 mm, respectively, P = 0.13) using ANCOVA analysis. Multivariable logistic regression adjusting for potential confounding factors showed that usual or uncontrolled Bp control were associated with having carotid plaque (OR = 1.08 and OR = 1.42, respectively), or elevated CIMT [Odd ratio (OR) = 1.17, 95% confidence interval (CI)1.04-2.24, and OR = 1.54, 95% CI 1.36-2.96, respectively compared to tight Bp control; but did not show glycemic control as independent predictor of either having carotid plaque or elevated CIMT. Conclusions In older patients with hypertension and diabetes, blood pressure control, but not glycemic control is associated with subclinical carotid atherosclerosis.
