The principles, methods and progress in recent years of these technologies were also introduced. At the same time, this paper also compares the advantages and dis-advantages of these methods. People should choose suitable method according to their purposes.

Tsutsugamushi disease is an acute infectious rickettsial disease caused by the intracellular parasite Orientia tsutsugamushi. Due to its variety of clinical signs, this disease is often misdiagnosed. This article examines a total of 4 patients who visited our clinics with fever and sore throat. 3 of them had body temperature of 39.5 Celsius degrees when admitted. The characteristic black eschar occurred on 4 of them. Lymphadenopathy occurred on 2 of them. Cough occurred on 1 of them. Lab tests showed that 3 of them had Leukocytosis, 1 of them had increased bronchovascular markings, and 3 of them had Weil-Felix test positive. After admission, all patients, who were confirmed of diagnosis of tsutsugamushi disease instead of tonsillitis, received the comprehensive treatment and cured afterwards.

Objective To investigate the efficacy,side effects and cosmetic effects of breast-conserving operation combined with radiotherapy for patients with breast cancer. Methods Forty-three patients with early stage of breast cancer(n=30 for stage I and n=13 for stage II) were performed extended resection plus axillary lymph node dissection or quadrant resection plus axillary lymph node dissection.After operation,tangential field irradiation was conducted with 50 Gy of X ray,tumor bed was irradiated with additional 10 Gy of electron beam,and supraclavicular field irradiation was also administered with 30 Gy of X ray and 22 Gy of electron beam. Results There was no recurrence during the follow up for 14 to 50 months.The acute side effects of radiotherapy included breast complaints(n=10,grade Ⅰ,23.26%),skin erythema and hyperpigmentation(n=19,grade Ⅰ,44.19%),moist desquamation(n=5,grade Ⅱ,11.63%) and radiation esophagitis(n=4,grade Ⅰ,9.30%),while one patient experienced radiation esophagitis one month after radiotherapy.No such complications as skin fibrosis and necrosis,angiotelectasis,breast and upper extremity edema occurred.The short-term cosmetic effects were satisfactory to 93.02% of all the patients. Conclusion For early stage of breast cancer(stage I and stage Ⅱ),breast-conserving operation combined with radiotherapy may yield satisfactory survival rate and short-term cosmetic effects,as well as low incidences of side effects.

Objective To provide evidence for the application of nutritional intervention strategy by analyzing perioperative nutritional status of retroperitoneal liposarcoma patients.Methods 60retroperitoneal liposarcoma patients were divided into primary group (27 cases) and relapse group (33cases).These patients were put on nutritional risk evaluation using nutritional risk screening (2002)(NRS2002) within 24 hours of admission,and the serum albumin (ALB) value was recorded.Results Preoperative NRS2002 score showed that relapse group had a higher chance of cacotrophy.Serum albumin level from different time point showed that patients in relapse group were more prone to cacotrophy (respectively t =9.174,4.720,10.950,8.772,10.960,all P ＜ 0.05) and subject to slower recovery of gastrointestinal function [(86 ± 15) h vs.(61 ± 6) h] (t =7.903,P ＜ 0.05),prolonged antibiotic use [(15.5 ± 5.6) d vs.(7.3 ± 0.7) d],t =7.55,P ＜ 0.05),the average length of hospital stay was longer [(25.5±6.0) d vs.(14.1 ± 1.7)d] (t =9.571,P＜0.05),and higher inhospita cost [(13.2±5.6) × 104 yuan vs.(6.8 ± 0.9) × 104 yuan] (t =5.871,P ＜ 0.05).Though there was no difference between the two groups in incision complication rates (x2 =2.625,P ＞ 0.05)Conclusions Retroperitoneal liposarcoma patients has perioperative nutritional risk.Compared with the primary group,patients from relapse group have higher chance to got cacotrophy.NRS2002 scoring system is simple,it could be used in predicting nutritional risk for those patients.

Objective To investigate the method of esophageal protection and nursing of pa-tients during peri-ablation of atrial fibrillation. Methods 31 patients hospitalized from June to July,2007 underwent radiofrequeney ablation under the mapping of Carto system, who were treated with liq-uid diet, anti-acid drugs and lowering energy ablation in posterior wall of left atrium for the aim of esophageal protection. Results The success rate of ablation was 100% with no occurrence of atrial-esophgeal fistula and uneomfort of digestive tract. Conclusions Careful esophageal protection and nursing plays an important role in prevention of atrial-esophgeal fistula.

Objective To investigate the microbiological and epidemiological characteristics of bloodstream infections in Peking University Third Hospital Methods The clinical, microbiological and epidemiological data of bloodstream infections in Peking University Third Hospital from January lst,2005 to December 31st, 2007 were analyzed retrospectively. Differences in proportions were compared using X2 test. Results Six thousand four hundred and eighty-eight blood culture tests for 5 138 episode of bloodstream infections of 3 795 patients were performed. The positive rate was 9.9%. The average incidence rate of nosocomial infection was 40.8 cases per 10 000 hospital admissions. In the 593 pathogens, 483 (81.5%) were pathogens causing nosocomial. The ratio of Gram-positive microbs, Gram-negative ones and fungi (all were Candida spp.) were 38.5%, 54.7%, and 6.8%, respectively. The corresponding ratio of nosocomial pathogens were 42.0%, 49.9% and 8.1%, respectively. The most frequently isolated strain was Escherichia coli (25.3 %). The coagulase negative staphylococcus was the second one (18.8%). The corresponding ratio of Staphylococcus aureus, Klebsiella pneumoniae, Enterococcus spp. , Pseudornonas aeruginosa , Acinetobacter baumannii and anaerobs were 7.1%, 7.4%, 8.3%, 3.2%, 2.2% and 0.7%, respectively. Ten patients (1.7%) had experienced polymicrobial infection. In hospital setting, Streptococcus spp. And Escherichia coli infections were more frequently in non-intensive care unit (ICU) than ICU (X2= 9.240, P= 0.002; X2= 23.609, P,<0.01; respectively). But the infection rate of Candida spp. Was significantly higher in the ICU (X2= 5.498, P= 0.019). The time interval between hospital admission and onset of infection for the most frequently isolated pathogens ranged from 15.1 days (Escherichia coli) to 29.7 days (Acinetobacter baumannii). The degree of resistance to the common antimicrobal agents had no change in the three years. Conclusions The average incidence rate of nosocomial bloodstream infection is 40.8 cases per 10 000 hospital admissions. The main pathogens are the Gram-negative microbs.
