OBJECTIVE To investigate the classification and antibiotics resistance of Staphylococcus in children with septicemia in recent two years and to provide data for clinical treatment. METHODS All the blood specimens delivered by pediatrics were identified and detected the antibiotic resistance with Microscan Auto SCAN4. RESULTS Totally 268 Staphylococcus strains were collected. Among them,S. aureus was 114 strains (42.5%),coagulase-negative Staphylococcus were 154 srains. Among 114 S. aureus strains,meticillin-resistant Staphylococcus aureus (MRSA) were 79 strains (69.3%). Among 154 coagulase-negative Staphylococcus strains,meticillin-resistant coagulase-negative Staphylococcus aureus (MRCNS) were 102 strains (66.2%). The drug sensitivity results showed that meticillin-resistant staphylococcus (MRS) were highly resistant to 15 commnly used antibiotics than meticillin-sensitive Staphylococcus (MSS) and showing multi-drug resistance. No vancomycin-resistant strains were found.CONCLUSIONS Children with septicemia infected by Staphylococcus are increasing recently. Identification and antibiotic resistance of clinical isolated Staphylococcus must be strengthened,and give the effective data for clinicians.

Early mobilization is beneficial in the prevention of intensive care unit acquired weakness. This paper summarized the meth-ods, opportunity, evaluation of early mobilization intervention, and some notes.

Modified constraint-induced movement therapy (mCIMT), which is modified from constraint-induced movement therapy (CIMT), is used in hemiplegics for rehabilitation. It may be used in the selected patients in certain function and age. mCIMT is more flexible than CIMT, which is mainly consisted of intervention movement, intensity, and the time of training and limitation. mCIMT is also used with other rehabilitation methods. There are various assessment for the evaluation of upper extremity motor function. By using Contract and Mo-tor Activity Log, researchers can better guarantee the curative effect.

Diabetic foot infection may hamper wound healing and lead to non-traumatic amputation in diabetes patients and early diagnosis and proper treatment can improve prognosis.In this review,the progress in classification,influencing factors,diagnostic methods and local treatment of diabetic foot infection is introduced.

OBJECTIVE:To establish a method for bacteria1 endotoxin test for Peramivir hydrate and sodium chloride injec-tion. METHODS:Maximum non-interference concentration of the sample with different batohes were used for interference test. was determined by interference test according to endotoxin gel method stated in Chinese Pharmacopiea (2010 edition)and bacterial en-edotoxintest by tachypleus amebocyte lysate from 2 manufact urers. RESULTS:The interference on bacterial endotoxin test could be excluded when the sample was diluted to 2.5 mg/ml and the limit of bacterial endotoxins was 0.5 EU/ml. CONCLUSIONS:The established method can be used to detect the bacterial endotoxin of Peramivir hydrate and sodium chloride injection.

Objective To investigate the effect of wire?reinforced epidural catheters on the success rate of epidural catheterization for labor analgesia. Methods A total of 200 nulliparous parturients who re?ceived labor analgesia voluntarily, of American Society of Anesthesiologists physical status Ⅰ or Ⅱ, aged 20-45 yr, with body mass index<35 kg∕m2, were divided into 2 groups (n=100 each) using a random number table: common catheter group ( group Ⅰ) and reinforced catheter group ( group Ⅱ) . After suc?cessful epidural puncture, the corresponding catheter was inserted inⅠandⅡgroups. The development of difficult insertion, intravascular catheter insertion or paresthesia during insertion was defined as a failure of epidural catheterization. The occurrence of the failure of epidural catheterization was recorded. Results Compared with group Ⅰ, the failure rate of epidural catheterization was significantly decreased in groupⅡ( P<0.05) . Conclusion Wire?reinforced epidural catheters can raise the success rate of epidural catheter?ization for labor analgesia.

BACKGROUND:Exercise can elicit generation of coronary col ateral circulation through numerous pro-angiogenic growth factors. It is not enough via a single factor to clearly definite signaling pathways for the generation of col ateral circulation. Many pro-angiogenic growth factors are involved in kal ikrein-kinin system, and there is no report about exercise effects on this system.
OBJECTIVE:To study effects of exercise training on bradykinin expression in rats with myocardial infarction.
METHODS:Thirty Wistar rats were randomly assigned to control group, myocardial infarction group and exercises training group. Rats in the control group were subjected to thoracotomy with no coronary artery ligation. Rats in the other two groups were modeled. In the exercise training group, 3 days after myocardial infarction, rats were subjected to 30-minute exercise training on treadmil , once a day for 4 weeks. At the terminal of the experiment, blood samples were obtained to analyze bradykinin expression by enzyme linked immunosorbent assay, and the myocardium was sampled to analyze relative blood flow by microsphere method.
RESULTS AND CONCLUSION:After exercise training, bradykinin level in the exercise training group was significantly higher than that in the myocardial infarction group (P<0.001). At the end of experiment, the relative blood flows of the exercise training and myocardial infarction groups were both increased compared with before experiment (P<0.05, P<0.001). At the end of experiment, the relative blood flow of the exercise training group was significantly higher than that of the myocardial infarction group (P<0.01). In al the three groups, bradykinin level was significantly correlated with the relative blood flow in the myocardium. These findings indicate exercises training can improve bradykinin expression apparently and increase blood flow in the myocardium, which il ustrates that the kal ikrein-kinin system plays an important role in exercise induced angiogenesis.
