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.

OBJECTIVE To understand nosocomial candidal infection among tuberculosis patients and its drug(sensitivity).(METHODS) Totally 6280 clinical samples from Jan 2002 to Dec 2004 were cultured;and part of(positive) ones were tested their drug sensitivity to FC,FLC,KET and ITC.RESULTS From all cultured samples 2767 Candida strains(positive rate was 44.06%) were isolated.From them C.albicans,C.glabrata,C.tropicalis,C.krusei and other Candida were 2006, 344,206,95 and 116 strains,their positive rate was 31.94%,(5.48%),3.28%, 1.51% and 1.85%,respectively.Their drug sensitivity rate to four drugs were as follows: to FC was 93.73%,to TTC 62.76%,to FLC 51.03% and to KET was 47.59%. CONCLUSIONS The condition of(tuberculosis) patient would become serious due to higher dual infection rate by Candida after too long anti-(tuberculosis) treatment.Among the four kinds of drugs the FC has the best anti-candidal activity.

Objective To assess the value of preoperative MRI in predicting the incidence of cement leakage into adjacent discs during percutaneous vertebral augmentation (PVA) for osteoporotic vertebral compression fracture (OVCF).Methods Clinical and radiological characteristics of 127 patients who were treated with PVA for OVCF were analyzed retrospec tively.The following clinical data of these patients were analyzed,including gender,age,location of treated vertebral body and surgical approach.The image features of endplate injury,fracture line extended to the endplate,adjacent intervertebral dick injury and intravertebral cleft were evaluated on the preoperative MRI.The incidence of cement leakage into the adjacent disc were compared for the above factors with statistical methods.Results Totally 127 patients were enrolled in our study,including 179 treated vertebral bodies,358 endplates and 341 adjacent intervertebral discs.The incidence of intradiscal cement leakage was 57.73％ (56/97) in endplate injury sign,60.98％ (25/41) in fracture line extended to endplate sign,35.91％(51/142) in adjacent discs injury sign and 55.56％(20/36) inintravertebral cleft sign.The differences were statistically significant on preoperative MRI in patients with the above signs compared to those who had not (P＜0.05).The incidence of intradiscal cement leakage in percutaneous kyphoplasty (PKP) and percutaneous vertebroplasty (PVP) were 26.67％(16/60) and 42.86％(51/119),respectively,which was significant different (P=0.035).For bone cement volume ≤ 5 ml vertebral bodies,the incidence of intradiscal cement leakage was 31.19 ％ (34/109),lower than bone cement volume ＞ 5 ml vertebral bodies (47.14％ [33/70],P=0.031).There was no statistically significant association between intradiscal cement leakage and age,gender and location of treated vertebral body (P＞0.05).Conclusion Preoperative MRI can predict the leakage of bone cement into adjacent discs effectively during PVA.The PKP and the lower volume of bone cement injection can reduce the risk of intradiscal cement leakage.

Objective Unstable intertrochanteric fractures (ITFs) are mostly treated by proximal femoral nail antirotation (PFNA),Inter-Tan,Asian Hip,and other new internal fixation devices.But for complex unstable fractures,such as crushed lateral wall of the greater trochanter,the loss of fixation point on lateral wall slightly reduces the fixing effect.This study aimed to compare the biomechanical strengths between reversed less invasive stabilization system (LISS) and PFNA for treatment of unstable ITFs.Methods Forty synthetic femurs were used to simulate unstable ITFs in vitro and were fixed using the reversed LISS or PFNA.These fractures were divided into two groups depending on whether the lateral wall of the greater trochanter is intact or not (AO classification:31-A2.3 and 31-A3.3,respectively).The load-displacement of femur,stiffness,ultimate load,and cyclic fatigue resistance were detected using an incremental load test and a dynamic fatigue test through an MTS 858 test system.Results For both 31-A2.3 and 31-A3.3,the vertical sinking displacement (VSD) of the femoral head under 500 N load was insignificantly smaller after treatment with reversed LISS than with PFNA,and when the displacement was 5 mm,the femoral head bore insignificantly greater load.The fixation with reversed LISS resulted in greater axial stiffness of the femur but smaller ultimate load.During the same cycle in the dynamic fatigue test,the VSD was insignificantly smaller with the fixation of reversed LISS.Conclusion Reversed LISS and PFNA have similar biomechanical strength for unstable ITFs.This conclusion should be supported by additional large-size research on basic biomechanics and clinical application.This is the first comparative biomechanical study comparing reversed LISS and PFNA for unstable ITFs.
