Diabetes complicated with urinary tract infection is influenced by many factors, such as low immune function, high blood and urine glucose environment prone for bacterial growth, and nervous lesion.Diabetic urinary tract infections are characterized by insidious onset, high recurrence rate, correlation with high blood glucose and difficulty to control.The related bacterial pathogens are mainly gram-negative bacillus genus ( 58. 59%-76. 19%) , in which the detection rates of extended spectrum β lactamases( ESBLs) Escherichia coli and Klebsiella pneumonia were the highest, followed by Enterobacter cloacae. Gram-positive bacteria only accounted for 23%. Drug-resistant bacteria and fungi would increase under the condition of repeated infection and irrational usage of antibiotics.In recent years, the urine-derived sepsis caused by urinary tract infection had become a popular clinical research topic because of its concealed symptoms, acute onset, rapid development and high mortality. By reviewing domestic and foreign literatures and expert consensus, this article is intended to explore the characteristics and treatment of diabetic urinary tract infections to supply reference for early prevention, correct diagnosis and effective treatments.

Fever in patients with severe craniocerebral injury was a frequent occurrence.The rate of fever patients lead to plant man or death high up to 28％-72％.The univariate analysis found that there was significant association between fever and motality.One of the common cause of fever was non-infectious fever,which related with craniocerebral injury,including central fever,dehydration fever,clonus and rebleading fever.The major complication was central high fever after servere craniocerebral injury.The temperature high up to 39 ℃,which aggravated the original basic diseases,lead to respiratory and circulatory failure.Another cause of fever was infection fever which associated with nosocomial infection.Serious disease,long hospiltal stay,high proportion of invasive operation,coma were the high risk factors of patients with craniocerebral injury.The major type of nosocomial infection were pudmonary infection and surgical site infection.By reviewing domestic and foreign literatures and expert consensus,this article was intended to explore the characteristics and mechanism of fever in patients with craniocerebral injury.In order to reduce the secondary brain injury,decrease the disability rate,increase the sutrvival rate,diagnosis and treatment should be taken early.

OBJECTIVE To investigate pathogenic bacteria and prognosis of abdominal infection and take measures to prevent and control it.METHODS We analyzed the clinical material and prognosis of 31 patients with abdominal infection retrospectively according to the culture results of puncture and drain liquid from abdominal cavity from Nov 2007 to Nov 2008.RESULTS In 31 patients,5 were complicated with pulmonary infectionwhich the infection rate was 16.13%,and 7(22.58%) died.Totally 48 pathogenic strains were isolated from ascitic fluid culture,20 strains(41.67%) were Escherichia coli,11 strains(22.92%) were Enterococus.Some of coagulase-negative Staphylococcus,Streptococcus,Candida,Klebsiella pneumoniae,and Staphylococcus aureus were also isolated.The resistance rates of E.coli to cephalosporins were above 50.00%,to quinolones were above 65.00%.The susceptibility rates of E.coli to some ?-lactamases inhibitors and carbapenem were very high.The resistance rate of Enterococus to rifampicin was 63.64%,to piperacillin/tazobactam and piperacillin was 81.82%,to erythromycin was 100.00%.The susceptibility rates of Enterococus to teicoplanin,vancomycin,and linezolid were 100.00%.CONCLUSIONS The predominant pathogenic bacteria of abdominal infection are E.coli and Enterococcus.Abdominal infection tends to combine with pulmonary infection.The patients who got into multiple organ dysfunction syndrome have high mortality.

Objective To explore the relevance between fasting plasma glucose (FPG) level in early pregnancy and gestational diabetes mellitus (GDM). Methods Clinical data of 5299 singletonpregnant women accepted antenatal examination and delivered in the Department of Obstetrics and Gynecology, Peking University First Hospital from January 1, 2008 to December 31, 2009 were retrospectively analyzed. Results (1) The pregnant women were divided into 3 groups according to their FPG levels at early stage of gestation: Group A, FPG ＜5. 1 mmol/L (n= 4565); Group B,FPG≥5.1, but ＜5.8 mmol/L (n=701); Group C, FPG≥5.8 mmol/L, but ＜7.0 mmol/L(n=33). The incidence of GDM in Group A, B and C was 10. 69% (488/4565), 26. 11% (183/701)and 54. 55% (18/33). (2) The incidences of large for gestational age (LGA), cesarean section,premature birth, preeclampsia, neonatal hyperbilirubinemia, neonatal hypoglycemia, neonatal polycythemia, and neonatal infection were compared between Group A and B. The cesarean section rate [54. 63% (282/518)]and neonatal hypoglycemia rate [1.54% (8/518)]of those who were not diagnosed as GDM in middle and late term in Group B were higher than those of Group A [49.03%(1999/4077) and 0. 61% (25/4077)] (P＜0. 05); while there were no differences between the other six index of Group A and Group B (P＞0. 05). The prognosis of the GDM patients who did not accept gestational glucose management in two groups were similar (P＞0. 05), so did the prognosis of the GDM patients who accepted gestational glucose management in two groups. After combining the patients of the two groups who were not diagnosed as GDM as a new group, they were compared with those who did not accept gestational glucose management of the two groups (Group A2 and B2)respectively. The incidence of LGA rate of the new group was lower than that of Group A2 (12. 00%va 4. 94 %, x2=21. 4159, P＜0. 05) and Group B2 (18. 39 % vs 4. 94%, x2 = 28. 7189, P＜0. 05).Cesarean section rate of the new group was lower than that of Group A2 (57. 78% vs 49.64%,x2 =5. 6806,P＜0.05) and Group B2 (66. 67% vs 49.64%, x2 =9. 9003, P＜0. 05). And there were no differences between the other six index between the new group and the other two groups (P＞0. 05). Conclusions The diagnosis criteria of GDM set as FPG≥5.1 mmol/L at early stage of gestation, recommended by International Association of Diabetes and Pregnancy Study Group, is not applicable in China yet. Oral glucose tolerance test in middle and late term is still the most important diagnostic tool for GDM.

OBJECTIVE To investigate the status of traumatic infection among earthquake in order to provide reasonable evidence for anti-infective therapy. METHODS Samples were collected from 14 patients with compound fracture or osteofascial compartment syndrome for bacterial,fungal and anaerobic culturing,then according to pathogens to choose antimicrobial susceptibility test (AST). RESULTS Among 14 victims,10 had germ growth in wound secretions,the infection rate was 71.43%. Among 17 samples the bacteria,fungi and anaerobic were isolated in 12,4 and (samples,respectively),the isolated rates were 70.59%,23.53% and 5.89%. The main pathogens for the first culture were Enterobacter cloacae,coagulase negative Staphylococcus (CNS) and Acinetobacter. The Clostridium tetani and C. perfringens were all negative. We also isolated 5 strains of fungi from them 1 strain of Candida. CONCLUSIONS Most of the victims from disaster area have got bacterial infection. Most of them are combined infection,some of the infections are nosocomial infections. The key points of the treatment are to find pathogens immediately and choose a reasonable antibacterial agents according to the AST.

OBJECTIVE To enhance the healing rate of the wounded victims in earthquake and to do a good job on the nosocomial infection prevention and control according to the feature of the victims. METHODS The advance medical team on the train evaluated thd traumatic condition of the victims and sorted them according to their condition,then the victims with raw surface infection and that with no wound were arranged to the different sections and wards.The cleaning and medical inspection procedure for the victims were formulated.The secretions of their open wound surface with bacterial,fungal and anaerobic culturing at the very beginning were taken when their traumatic condition were examined.The management of wards,attendants and visitors were strengthened,the hand hygiene compliance and the right way to disposal clinical waste the disinfection and sterilization were supervised and directed. RESULTS Most of the 76 victims were with limbs injury,of which 14 victims with open injury,10 got bacterial or fungal infection.The infection rate was 71.43%.Most of them had got combined infection.No Clostridium tetani and C.perfringens were isolated from the secretion of the raw surface.Three victims were complicated with urinary system infection,1 with pulmonary infection and 1 with bed-sore infection after wounded in earthquake.Basing on effective debridement and change dressings,the antibacterial agents were applied according to pathogenic bacteria and the antimicrobial susceptibility test,so the wound surface and general infection were controled effectivelly.Another 35 victims with closed fracture who were operated with internal fixation and reposition after discection in the limited time were not infected. CONCLUSIONS The infection rate of raw surface of victims with open injury is high.Most of the wound surface are infected with some multidrug resistant bacterial and fungi and combined with urinary system infection or pulmonary infection.The nosocomial infections precaution and control should be strengthened to prevent cross infection when treating the victims wounded in earthquake.
