OBJECTIVE: To avoid the infection induced by the clinical application of total parenteral nutrition solution( TPN) . METHODS: The experience of quality control and etiological examination in the preparation and application of TPN for 62 patients in our hospital were analyzed retrospectively. RESULTS & CONCLUSION: The key to reduce the incidence of infection in the preparation and application of TPN is to keep the infection source under control.

Objective Good culture sense of patient safety among the hospital staff is in close relation with the improvement of medical quality and patient safety .The article was to provide evidence for the culture management of patient safety and related stud -ies.Methods We searched the main databases Pub Med , Chinese Bio-medical Literature Database , CNKI, Wan-Fang database with the key word safety environment,safety culture,safety approach,evaluate,assessment,situation analysis,analy-sis. Results 50 literatures were collected.The assessment tools could be divided into self-made questionnaire (13, 26%), im-proved questionnaire (16, 32%), chineselized foreign questionnaire (21, 42%).The main researchers (84%) and study objects (66%) were nurses.48 (96%) investigation and descriptive study were about patient safety culture;only 2 documents made compari-son before and after the patient safety culture cultivation . Conclusion The research of patient safety culture in our country is rising currently, while the development of assessment tools is still at exploration stage .The width and depth of related research should be fur-ther broadened .

Objective: Large-conductance calcium-activated potassium (BKCa) channel modulates vascular smooth muscle tone. In the present study, we tested the hypothesis that salt, one of the factors which significantly influence blood pressure (BP), can regulate BKCa activity and then elevate blood pressure. Methods: Male Sprague-Dawley rats aged 6 weeks were randomized into high salt diet group (HS) and control group, fed with high salt diet (containing 5% NaCl) and standard rat chow (containing 0.4% NaCl) respectively for 16 weeks. Tail systolic blood pressure (SBP), body weight (BW) and 24-hour urinary output were tested every 4 weeks. Content of urinary Na+ was detected using flame spectrophotometrical method. At the end of 16 weeks, all the rats were killed, the mesenteric arteries were obtained, and single mesenteric smooth muscle cells were isolated at once. The resting membrane potential (Em), the total potassium currents and the currents after perfusion with TEA solution of the cells were all recorded by whole cell patch clamp. The transcriptions of BKCa channel α and β1 subunits in mesenteric arterial vascular smooth muscle cells (VSMC) of each group were calculated by real-time RT-PCR. Results: There was no difference in SBP and BW at each stage between control group and HS group; the urinary Na+ level in HS animals was elevated significantly after 4 weeks. The negative values of Em in HS group VSMCs were reduced compared with those in the control group. Transcriptions of β1 subunit of BKCa channels were decreased in HS group, but α subunit transcriptions did not differ between the two groups. Whole cell potassium currents did not differ between HS and control groups, but BK Ca currents of HS group VSMCs were lower than those of control group ones. Conclusion: Even without elevating SBP, salt-loading can still modulate the expression and activity of BKCa channel in the mesenteric arterial VSMC and elevate vascular tone.

The bone turnover markers are composed of the metabolic products of bone matrix and bone cells.The changes of these markers in serum and/or urine represent the status of bone metabolism.To measure the level of these markers will offer important information for evaluating the diagnosis and the responses of therapy in metabolic bone diseases,and to predicat the risk of bone fracture.The biochemistry,measurement and clinical aplication will be introduced in this paper.

Objective To investigate the pathogenesis of hyperthyroidism combined with cerebral infarction and the relationship between hyperthyroidism and cerebral infarction. Methods Data from the clinical manifestations, diagnosis, and therapeutic outcomes of 10 patients with hyperthyroidism combined with cerebral infarction were analyzed retrospectively. Results After treatment with drugs for anti hyperthyroidism and active treatment of cerebral infarction, no severe complications were found in all patients. Conclusion Hyperthyroidism combined with cerebral infarction may be one of the important causes of adolescent cerebral infarction. Treatment of hyperthyroidism may play an important role in the treatment of cerebral infarction.
