OBJECTIVE: To explore the regularity and characteristics of ADR induced by levofloxacin. METHODS: Retrieved from, CHKD of CNKI and Wanfang database, a total of 205 literatures about levofloxacin-induced ADR were collected and analyzed statistically in respect of patients’ gender, age, case history, administration route, clinical manifestation and result of treatment. RESULTS: 483 cases(92.9%) were given levofloxacin intravenously in total of 520 ADR cases. 156 cases were characterized with lesion of skin and its appendants (30.0%), followed by lesion of nervous system (n=133, 25.6%), lesion of cardiovascular system (n=65, 12.5%) and anaphylactic shock (n=45, 8.7%). The earliest ADR occurred within 2 min after administration while the latest occurred in 34 d after administration. 514 cases recovered when drug withdrawal or treatment were taken. However, there were 2 cases of sequelae, 4 cases of death and 62 cases of unexpected serious ADRs. CONCLUSION:ADRs induced by levofloxacin present complicated and various symptoms caused by several factors in which the most serious result in death. Clinical doctors should pay more attention to levofloxacin-induced ADRs.

Objective To observe the incidence of acute radiation pneumonitis (RP)after intensity modulated radiation therapy,and to explore the relationship between the incidence of RP and the parameters from dose-volume histogram (DVH)in the patients with non-small cell lung cancer (NSCLC).Methods By Pinnacle 7.6c TPS, 46 patients with NSCLC were treated by IMRT.The values of the percentages of the lung volumes receieved 5, 10,20,and 30 Gy radition to the total lung volumes (V5 ,V10 ,V20 ,V30 )and mean lung dose (MLD)were observed,and its correlation with acute RP was analyzed.Results The incidence of acute RP of the patients with NSCLC was 37.0% (17/46),among then there were 29 cases (63.0%)of Grade 0 (non-pneumonitis group), 12 cases (26.1%)of Grade 1,5 cases (10.9%)of Grade 2,and there were no Grade 4 and 5 RP.The values of V5,V10,V20,V30,and MLD of lung were 53.34 %,43.12%,24.15%,15.36 %,and 16.02 Gy.The values of V5,V10,V20,V30,and MLD in pneumonitis group were 57.81%,48.91%,31.34%,17.83%, 21.71 Gy,and they were 49. 81%,39.78%,21.82%,13.12%,and 13.71 Gy in non-pneumonitis group, there were significant differences between two groups (P<0.05).Conclusion The intensity modulated radiation therapy in treatment of NSCLC can protect the lung tissue,and the parameters of DVH such as V5 ,V10 ,V20 , V30 and MLD can predict the occurrence of RP.

Primary biliary cirrhosis (PBC) is a slowly progressive autoimmune disease of the liver.Studies on the pathphysiology of this disease have demonstrated the immune-mediated destruction of the intrahepatic bile ducts and portal infammation seem to be the result of an intense autoimmune response directed against the autoantigens located in the biliary epithelium.Immunologically,PBC is characterized by the presense of antimitochodrial antibodies,elevated serum IgM and lymphoid infiltration in the portal tract.Indeed,the relationships between IgM and PBC have been a major focus of research on its pathphysiology,which lead to an increased understanding of the abnormal immune responses involved in PBC.This review summarizes data on the biological and clinical significance of Hyper-IgM in PBC,and highlights the potential role of IgM for the diagnosis and treatment of PBC.

Objective To evaluate the learning curve in percutaneous nephrolithotomy under the guidance of B ultrasonography.Methods From January 2006 to July 2007,totally 60 cases of percutaneous nephrolithotomy were performed under the guidance of B ultrasonography by a single urologist.The patients were divided into 6 groups according to the date of the operation(10 cases in each).The time for setting the renal access and the stone-free rate were compared among the groups.Results The time for setting the renal access was(15.0?2.7),(14.0?2.1),(10.2?1.2),(5.8?0.7),(7.5?1.2),and(6.6?0.9)minutes respectively in group 1 to 6.ANOVA analysis showed significant difference among the groups(F=5.734,P=0.000).Significant difference was detected between groups 1 and 4(q = 5.655,P

Objective To compare the effects of butorphanol,midazolam and innovar on relieving appendix traction response during appendectomy. Methods Sixty-eight patients who underwent appendectomy were randomly divided into butorphanol group(n=21),midazolam group(n=23) and innovar group(n=24).Butorphanol,midazolam and innovar were intravenously administered to patients during skin incision.The appendix traction response,sedation score,heart rate(HR),mean arterial pressure(MAP) and pulse oxygen saturation(SpO2) were recorded and compared among groups.Results Compared with those before operation,there was no significant changes in HR,MAP and SpO2 during operation.The effective rates of butorphanol,midazolam and innovar in relieving appendix traction response were 95.2%,65.2% and 50.0%,respectively.Butorphanol surpassed midazolam and innovar in sedation and relieving appendix traction response(P

The subjects examined were 398athletes. The method used included both questions and clinical examination. The differences of the data obtained all underwent Chi Square (X~2) test. Result of the investigation showed: the site of the highest incidence of injury was the ankle, 38.4%; the nextwas the knee, 26. 1%; the foot, 15. 3%; low back, 10. 3%; the thigh, 6. 8%; Tendo Achilles, 6. 5%; tibia, 4. 5%and fibula, 2. 3%. The incidence was relatively higher wbenever the injury had any relation with the shape ofthe knee (genu valgum, genu recurvatum), hallux Yalgus, c avus and callus and tarsal navicular. The differencesamong incidences of injury related with the shape of the lower limbs are of important statistical significance.As for the incidence of abnormal shape of limbs, genu valgum and recurvatum are outstanding in female wbilegenu varum occurs much more in male. This article is emphasized on the analysis of the mechanism of the influence of limb shape on injury;and it is thought that it is mainly due to changes in the line of force. In the authors' opinion, in the choiceof high level athletes, those who have such abnormal anatomy of their limbs should not be selected.

Objective To evaluate the therapeutic effects of combined recombinant human IL-11(rhIL-11) and recombinant human G-CSF (rhG-CSF) on the neutron-irradiated dogs. Methods 18 male beagle dogs were divided into radiation control group (C, n=7), symptomatic treatment group (S, n=4), and combination therapy group (T, n=7). All dogs were exposed to total body 2Gy 90% neutron radiation. From the first day after radiation, the animals of group T received rhG-CSF 10?g/(kg?d) and rhIL-11 50?g/(kg?d) subeutaneously for 14d and 21d respectively. The cell counts of peripheral blood and CFU-GM of bone marrow were carried out. Results All animals of group S and T survived, however, the survival rate of group C was only 57%. The cellcounts of T group peripheral blood cells (white blood cell at any time point , the platelet and red blood cell of recovery phase) were higher than that of C or S group. The count of T group bone marrow CFU-GM was 6 fold higher than that of group C or S on day 1, and still 1.75, 1.46 fold higher than that group C or S, respectively, on day 33. Conclusion the combination therapy of rhIL-11 and rhG-CSF significantly raised the white cell and platelet counts in ARS dogs induced by neutron irradiation by accelerating the recovery of bone marrow hematopoietic function.

Objective To establish lung adenocarcinoma drug resistance cell strain induced by cis-diaminodichloroplatin and investigate the biologic characteristics and chromosome karyotype of cell strain.Methods Large dosage impact and step by step inducing method were used to establish A549 and SPC-A-1 drug resistance cells: A549/CDDP and SPC-A-1/CDDP.MTT was used to detect the cell drug resistance index. Bioluminescence was used to detect the energy metabolism.Cell cycle was analysed by flow cytometer.The differential staining technique and SKY were used to analyze the chromatosome of A549/CDDP and SPC-A-1/CDDP.Results The drug resistance index of A549/CDDP and SPC-A-1/CDDP were 14.0 and 12.0. The content of ATP,ADP and AMP decreased significantly.The cell cycle of A549/CDDP and SPC-A-1/CDDP were of no notable changes.The results of the differential staining technique and SKY showed that the chromatosome of A549/CDDP and SPC-A-1/CDDP had several derivative chromosomes.Both cells had the same derivative chromosome: der(21)t(21;22).Conclusion CDDP can induce lung adenocarcinoma cell strain drug resistance.The derivative chromosome,including der(21)t(21;22) may have relationship with the drug resistance of cell strains.
