OBJECTIVE:To investigate the perioperative use of antibiotics in patients with acute appendicitis.METHODS:The perioperative use of antibiotics in 330 surgery patients with acute appendicitis from Jan.2003 to July 2006 in a 3-A grade hospital was analyzed retrospectively in respect of drug variety,DDDs,drug combination,administration etc.RESULTS:A total of 6 groups(25 kinds)of antibiotics were used in all the 330 cases,of whom,8(2.42%)used single kind,259(78.48%)used two kinds concomitantly,and 63(19.09%)used 3 kinds concomitantly;43(13.03%)used antibiotics rationally,and 287(86.97%)used antibiotics irrationally;61.21% were not given antibiotics before operation.The average medication time for patients without preoperative use of antibiotics was 8.68 d vs.7.53 d for those with preoperative use of antibiotics,showing significant differences between the two groups(P

Most previous researches on nuclear factor κB (NFκB) are limited to immune cells. Recently, however, researches on NFKB in muscle cells attract more attention. Target genes of NFκB encodes proteins with different functions, accordingly NFκB can not only induce inflammation deterioration, protein degradation and tissue injury but also promote cell growth and maintenance. But the inhibitation effect of NFκB inhibitors is not related with its antioxidant capacity. Exercise can activate NFκB during which process NFκB may act as an inducer of cell growth and development which is different from its role under pathological situation. This article sums up and analyzes the effect of NFκB on cell growth, the changing trend and effect of NFκB in skeletal muscle under exercise, providing data for the researches on muscle rehabilitation and motion fitness change.

Lactate shuttle is the process of lactic migration thmugh membrane with monocarboxylate transporters(MCTs)and anti-exchange ion,including intracellular and extracellular modes.The effect of MCTs specific distribution on lactate shuffle and the structure and mechanism of anti-exchange ion transporter is unclear.Any factor which infiuences lactate production.oxidation,MCTs expression and blood circulation can regulate lactate shuttle.That lactate induces ASIC channel to open may affect the Sensory nerve bnnging about pain.Various lactate shuttles may induce vanous kinds of pain,Ageing,but not inactivity,decrease lactate accumulation and shuttle leading to the decreased fatigability of skeletal muscle.The regulation mechanism and energy supply extend of lactate shuttle need to be investigated.Lactate shuttle may be one important factor to regulate the biological effect of lactate such as vanous muscle pain,fatigability and etc.Lactate shuffle effect on body function regulation is a noticeable problem in muscle rehabilitation and excise-inducad adaption fields.

OBJECTIVE:To probe into the characteristics of adverse drug reactions (ADR) occurred in our hospital. METHODS: 340 ADR cases collected from Jan. 2004 to Dec. 2008 in our hospital were analyzed retrospectively. RESULTS: Of the total 340 ADR cases,80 (23.53%) were collected from pharmacy department;63.83% occurred in patients aged from 21 to 60 years,with females showing higher proportion than males;83.24% were induced intravenously,48.08% were induced by anti-infective drugs,of which,cephalosprins and quinolones took the lead. 38.05% of the ADR manifested as lesion of skin and its appendants. CONCLUSION: ADR monitoring should be strengthened in clinic;furthermore,the quality of ADR reporting should be improved and the use of drugs should be rationally in a standard way so as to lessen or avoid the occurrence of ADR.

OBJECTIVE: To study the photostability of the levofloxacin hydrochloride injection. METHODS: The content of levofloxacin hydrochloride was determined and its UV spectra changes were observed after being lighted by three different light sources-the UV light, the sunlight and the natural light for different periods of time. Whether there is any decomposed product or not was determined by TLC. RESULTS: There were decompositions of levofloxacin hydrochloride injection subjected to illumination from three light resources, with that under the sunlight decomposed faster; Rf value under TLC of the decomposed product was found to be 0.72. CONCLUSION: Levofloxacin hydrochloride injection should be kept away from UV light, the sunlight and the natural light.

To explore the safety and efficacy of left atrial appendage (LAA) occlusion under the guidance of local anesthesia and modified transseptal puncture technology by coronary sinus assisted positioning in patients with nonvavular atrial fibrillation (NVAF). Methods: A total of 16 NVAF patients received local anesthesia and percutaneous LAmbre or Amplatzer cardiac plug occluder implantation. There were 12 males and the patients mean age was at (71.0±6.0) years with CHA2DS2-VASc score at (4.1±1.5); all patients had walfarin contradiction or with walfarin related side effect. Transseptal puncture was conducted by coronary sinus catheter as the anatomic location marker. Results: All 16 patients finished transseptal puncture and no relevant complication occurred. 15/16 (93.8%) patients had successful LAA occlusion, 1 patient was abandoned because of LAA anatomic structure variation. The mean operative time was (65.0±23.0) min and the mean X-ray exposure time was (12.0±3.0) min. The mean diameter of occluder was (32.5±6.0)mm. Conclusion: LAA occlusion was safe and effective with local anesthesia and modified transseptal puncture technology by coronary sinus assisted positioning in relevant patients.
