Purpose:To investigate the susceptible factors and treatment against cross infection in hospital of cancer patients.Methods:174 cases of cross infection in hospital of cancer patients from 1997 to 1999 were analyzed for infective site, infective agent and infectious bacteria. Results:174 cases of cross infection in hospital of cancer patients were found, which was 10.45% of the in paitents of the same period. The majority (108/174) had infection of tissues and organs within irradiation fields after radiotherapy. Respiratory tract infection rate was 76.43%. 16 cases (40.0%) were found to have secondary infection of digestive canal after chemotherapy in the 40 cases of infection of digestive canal. Bone marrow deression or chronic failure and long term decubitus were also causes of infection. In addition, mycotic infection was 43.42% (33/76) in bacteriological tests with bad prognosis.Conclusions:Cross infection in the hospital occurs that patients enfeebled by radiotherapy, chemotherapy, chronic bone marrow failure and long term decubitus. Attention should be paid to the possibility of mycotic cross infection in hospitals, as the prognosis could be quite serious. As soon as the diagnosis is confirmed, early and full dose treatment by anti mycotic drugs should be given.

Objective To observe the curative effect and prognosis of cough variance asthma(CVA) evoked by mycoplasma pneumonia(MP) treated by azithromycin combined with pumicort and bricasol.Methods 126 CVAs evoked by MP were divided randomly into two groups:the therapeutic group,were given azithromycin orally and inhaled pumicort and bricasol,the control group,were treated only by azithromycin orally.The remission rate and recurrence rate of cough between the two groups were compared.Results The remission rate and recurrence rate of cough of therapeutic group were 100% and 15.9% respectively while those of the control group were 28.6% and 60.3% respectively.The difference between two groups was significant.Conclusion Azithromycin combined with pumicort and bricasol can improve significantly the curative effect of CVA evoked by MP,decrease the recurrence and make for the prognosis.

Objective: To investigate the impact of intravertebral cleft on adjacent vertebral fracture (AVF) after percutaneous vertebral augmentation. Methods: Data of 172 patients with osteoporotic vertebral compression fracture (OVCF) who underwent percutaneous vertebral augmentation were retrospectively analyzed. The patients were divided into intravertebral cleft group (n=37) and control group (n=135) according to the presence or absence of intravertebral cleft before operation. The operative information and postoperative imaging characteristics were compared between 2 groups, and the impact of intravertebral cleft on AVF was analyzed. Results: The incidence of AVF after vertebral augmentation in intravertebral cleft group (54.55%, 24/44) was significantly higher than that in control group (23.21%, 39/168, χ2=16.39,P<0.01).The incidence of cement solid pattern distribution, intradiscal cement leakage and bone cement-bone surface fluid sign in intravertebral cleft group (84.1%, 43.2% and 63.6%) were all higher than those in control group (60.0%, 26.8%, 23.8%, χ2=8.82, 4.45, 25.34, all P<0.05). In intravertebral cleft group, the incidence of AVF in vertebral body with anterior wall height decreased ratio >50% (75.00%) was significantly higher than in those ≤50% (42.86%, χ2=4.24, P=0.04), but there was no statistical difference of the incidence of AVF among different fracture locations nor components (χ2=2.13, 0.27, both P>0.05). Conclusion: OVCF patients with intravertebral cleft are at increased risk of recurrence AVF after percutaneous vertebral augmentation, especially those with higher anterior wall height decreased ratio, postoperative bone cement mass distribution and bone cement-bone surface fluid signs and being required close follow-up observation.

Zebrafish toxicity assessment system is one of the important vertebrate model systems. Zebrafish is playing an increas-ingly important role in the field of toxicology studies because of its small size, short generation cycle, the transparent embryo and high reproductive rate. Now it is widely used in the embryonic derelopmental toxicology, pathological toxicology, environmental toxicology and other areas of toxicology studies with its unique advantages.
