Objective To observe clinical efficacy of recombinant human erythropoietin(rhu-EPO)in sepsis with anemia.Method From June 2005 to December 2006,sixty sepsis with anemia patients in the Second Affiliated Hospital of Tianjin Medical University were divided into control group(n=30)and theatment with rhu-EPO group(n=30).The exclusion criteria was:renal imufficiency patients needing blood purification,patients with hemorrhage of digestive tract,and patients who used rhu-EPO before.Patients in the rhu-EPO group were hypodermically injected with rhu-EPO at 48 hours after admission,6000 units par time,and continued every other day for two weeks.When the hemoglobin Was lower than 80 g/L,patients received red blood cell(RBC)transfusion or received other treatment decided by doctor.The data were expressed as(x±s),and were analyzed using Student's t test and Fisher's exact test with SPSS 11.5.A P valLie less than 0.05 indicated statistical significance.Results There Was no significant difference on hemoglobin between the two groups before treatment (P＞0.05).After treatment,the hemoglobin of patients in rhu-EPO group was higher than that in control group [(105.87±11.48)g/L vs.(91.23 ±19.89)g/L,P＜0.01].The units of RBC transfusions was less in patients of rhu-EPO group compared with control group[(2.0 ±0.47)U vs.(2.63±0.43)U,P＜0.01].There was no significant difference on mortality between two groups(P＞0.05).Conclusions In sepsis with anemia patients,administration of rhu-EPO every other day can increase red blood cell level and reduce RBC transfusion.

X-ray repair cross-complementing group 1 gene ( XRCC1 ) serves as one key DNA repair gene. The polymorphism of XRCC1, resulting in the changes of corresponding amino acid and the effect of DNA repair, may contribute to the radiation injury of malignant tumor patients. Current studies have revealed that single nucleotide polymorphisms of XRCC1 may be involved in the radiation injury for patients with tumor. Nevertheless this correlation remains to be further investigated.

Objective To study far femoral malignant bone tumor salvage limb treatment with allogeneic heterotopic half-joint transplantation and the use of GSH nail Methods Eleven cases with far femoral malignant bone tumor were administered tumor resection,transplanted with allogeneic heterotoeic bone half-joint,and fixed with GSH nail Results Nine out of the 11 cases were followed up.None of them had infection,rejection or heterotopic bone fracture.All of them can move with walking after 6 months.The effects of surgery was rated as excellent for 3 cases,fine for 4 cases andbad for 2 cases according to Mankin's rating criteria.Conclusion Salvage limb treatment for bone tumor can improve patients' quality of life.Allogeneic heterotopic bone,with rich source and acceptable joint surface,is a good graft for the treatment of bone defect after bone tumor resection.

Concurrent chemoradiation therapy is currently a recommended treatment approach for locally advanced inoperable stage ⅢA and stage ⅢB non-small cell lung cancer (NSCLC).There is no consensus on the optimal treatment regimen.It is one of these options for the consolidation chemotherapy following concurrent chemoradiation therapy.To date,there is no sufficient evidence indicating that consolidation chemotherapy following concurrent chemoradiation therapy further improves survival rates.The benefit remains to be confirmed by more clinical test.

Objective To investigate the relationship between monocyte chemoattractant protein-1 (MCP-1) gene -2518G/A polymorphism and cerebral infarction(CI) of Han population in Chinese Hunan district.Methods The -2518G/A polymorphism in MCP-1 gene was detected by polymerase chain reaction-restriction fragment length polymorphism analysis (PCR-RFLP) and DNA sequencing in 162 patients with CI (CI group) and 150 normal controls (NC group). The serum level of MCP-1 in the two groups was determined by enzyme-linked immunosorbent assay (ELISA).Results In CI group, genotypic frequency of GG was 39.5%, GA was 37.0%, and AA was 23.5%. The allele frequency of G was 58.0% and A was 42.0%. In NC group, genotypic frequency of GG was 27.3%, GA was 39.3%, and AA was 33.4%. The allele frequency of G was 47.0% and A was 53.0%. The frequencies of MCP-1 -2518GG genetype and G allele in CI group were significantly higher than those in CI group (all P

Objective To explore the neuroprotective mechanism of mild hypothermia by studying the effect of mild hypothermia on neuronal apoptosis after transient global cerebral ischemia in rats.Methods A model of transient global cerebral ischemia was made by bilateral common carotid artery occlusion and hypotension in rats. The neuronal demage in the CA 1 section of the hippocampus after cerebral ischemia was observed by nissel body stain mothed;apoptosis was detected by in situ end-labeling of fragmented DNA using the terminal deoxynucleotidyl transferase reaction (TUNEL) and the electrical microscope.Results The hippocampal CA 1 section neurons in normothermic ischemic group were significantly deficit as compared with the false operative group in mild hypothermic ischemic group (P

Objective To study the prevention and treatment of intra- or post- operative complications of radiofrequency ablation (RFA) for hepatic malignancy. Methods A series of 353 patients with primary hepatic carcinoma or secondary hepatic malignancy verified by pathological examinations and clinical manifestations underwent 452 times of RFA between October 1999 and March 2003, including 344 cases of percutaneous RFA and 9 cases of RFA during open surgery. There were 198 cases of primary hepatic carcinoma previously unoperated, 81 cases of recurrent hepatic carcinoma after surgery, and 74 cases of secondary hepatic malignancy. All the patients were followed up to make out short- or long-term surgical complications. Results Complications happened in 12 cases: skin burn by the electrode (2 cases), pneumothorax (1 case), right hydrothorax (1 case), vena cava thrombus (1 case), right bile duct injury and stricture (1 case), gastric external fistula (1 case), bile leakage in the left lateral lobe of the liver (1 case), hepatic abscess (1 case), external fistula of the ascending colon resulted from hepatic abscess (1 case), internal fistula of the duodenum, liver and right thorax resulted from hepatic abscess (1 case), and intra-abdominal hemorrhage (1 case). The incidence of complication was 2 65% (12/452) and the complication-related mortality was 8 33% (1/12). Conclusions RFA is a kind of minimally invasive procedure. But RFA especially percutaneous RFA may involve some risks for patients with the tumor located at the porta hepatic or the surface of the liver, or adhered to hollow organs, especially those who had a history of abdominal operation and adhesions of hollow viscera to the liver. Some complications can be prevented and effectively treated in the event of proper selection of patients, careful performance during the surgery, intensive postoperative care, effective hemostasia and efficient infection prevention.
