0.05).Conclusions:The incidence of CIN and especially high-grade CIN are higher in patients with positive high risk types of HPV-DNA than negative. HPV-DNA testing has significance in the diagnosis of cervical displasia;HPVDNA testing combined with pap smear and colposcopy can increase the diagnosis of cervical diaplasia.

The bioterrorism-related anthrax, the general situation of anthrax prevalence in China and the latest advances in laboratory diagnosis of Bacillus anthracis were reviewed. The control and prevention measures on anthrax were also introduced and the measures responding to the possible bioterrorism-attack were proposed in this paper.

Objective To study the long term results of condylar reconstruction using pedicled patella in the treatment of giant cell tumor of lower femur. Methods From August 1964 to December 1996, 6 patients with giant cell tumor in the lateral condyle of femur were treated with unicondylar resection curettage and reconstruction with pedicled patella autograft. There were 3 males and 3 females. The average age of the pateints was 30.5 years. The operative indications were as the following: tumor was located in one condyle, complicated with pathological fracture or the tumor had invaded underneath cartilage which was difficult for curettage. Surgical procedure included: Lateral condyle resection according to X ray or CT image, curettage of the possible remaining tumor tissues in the medial condyle. A muscle pedicle of 2.5 cm wide from the quadriceps was raised with the patella, then the articular surface of patella was used to reconstruct the articular surface of femoral condyle, ilium graft(sometimes allograft) was used to fill the defect proximal to the patella. The grafts was fixed by screws and(or) plates. Anterior cross ligament was fixed to the patella. Results 6 patients were followed up for a mean period of 136 months. There were no infection, recurrence, metastasis and instability. All patients could walk for a long distance. The range of motion of the involved knees was between 80? and 120?. There was no varus deformity under stress test, but about 5 degrees valgus deformity under stress test could be found in some, muscle strenth was 5 grade. Conclusion Pedicled patella autograft is a good method for the treatment of giant cell tumor that invades unilateral condyle of lower femur, it is specially suitable to the patients with pathological fracture or severe destruction underneath the cartilage. Thorough resection and curretage of the tumor, preserving the blood supply of patella, refixing the cross ligament, and lower placement of patella are the key points to obtain the satisfactory results.

Objective To evaluate the effect of one stage resection combined with chemotherapy for the treatment of colorectal cancer with hepatic metastasis.Methods In this study 17 out of 36 colorectal cancer patients with hepatic metastasis underwent one stage tumor resection embolization and chemotherapy via hepatic artery and portal vein through pumps in 10 cases. The remaining 19 cases in which metastatic tumors judged as nonresectable received embolization and chemotherapy alcohol injection and electrothermotherapy for the metastatic tumors.Results Recurrence developed in 6 out of 7 patients not receiving primary combined embolization and chemotherapy. The diameter of tumors in the 19 patients decrased by 57% on average, among which 4 patients underwent secondary resection of the metastatic tumors. The 1,2,3 year′s survival rate was 94%, 82%, 65% in combined group, and 74%, 53%, 32%(P

Objective: To investigate the role of endogenous nitric oxide (NO) in the pulmonary edema caused by overinfusion of colloid. Method: Forty healthy rabbits were randomly allocated into (Ⅰ) control group, (Ⅱ) infusion control group: one fold total blood volume of Gelofusine was infused at 2ml?kg~(-1)?min~(-1)(Ⅲ)L-NNA group:LNNA 20 mg/kg was intravenously injected before infusion, (Ⅳ)L-Arg+L-NNA group:L-arginine 300mg/kg and LNNA 20 mg/kg was intravenously injected before infusion. MAP,HR and CVP were recorded during the experiment, arterial blood gas analysis was examined before and after infusion,serumal NO value and lung water content were measured at the end of the experiment. Result: Overinfusion of colloid,L-NNA,an inhibitor of NO synthesis increased the extravascular lung water (EVLW) content and decreased NO value,meanwhile CVP increased,HR,PaO_2 and SaO_2 decreased,excess dose of L-arginine completely reversed the effect of L-NNA. Serumal NO value was negatively correlated with EVLW content (r=-0.94). EVLW content was significantly correlated with total lung water (r=0.41). Conclusion:Endogenous NO can reduce the pulmonary edema caused by overinfusion of colloid.

6) of platinum based intravenous chemotherapy prolonged the survival of patients with suboptimal cytoreduction Intraperitoneal chemotherapy was one of the dominant long term survival determinants, and mainly on those with size of residual disease less than 1 cm
