Objective To evaluate the clearance effect of hemodiafihration(HDF) and hemopeffusion combined with hemodialysis( HP + HD) on serum calcium,phosphorus and parathyroid hormone in patients with uremia.Methods Fifty-eight uremia patients treated with maintenance hemodialysis in our hospital from May 2009 to October 2010 were randomly divided into two groups:HDF group (n =29)and HP + HD group (n =29).Patients in HP + HD group underwent HD conventional treatment 5 times and HP + HD.treatment once every two weeks,while those in HDF group underwent HD treatment 5 times and HDF treatment once every two weeks.All subjects were treated for 12 weeks.Serum calcium,phosphorus and parathyroid hormone were detected and analyzed before and after the treatment.Results After therapy,the serum calcium ( [ 2.41 ± 0.32 ] mmol/L v.s.[ 2.22 ± 0.35 ] mmol/L,t =5.47,P ＜ 0.01 ),phosphorus( [ 1.98 ± 0.34 ] mmol/L v.s.[ 1.70 ± 0.31 ] mmol/L,t=8.13,P ＜0.01)and parathyroid hormone( [645.19 ± 184.52] ng/L v.s.[296.79 ± 103.54]ng/L,t =6.54,P ＜ 0.01 ) levels of HP + HD group decreased significantly.Similarly,the serum calcium ( [ 2.43 ± 0.33 ] mmol/ L v.s.[ 2.32 ± 0.37] mmol/L,t =6.72,P ＜ 0.01 ),phosphorus ( [ 1.97 ± 0.36 ] mmol/L v.s.[ 1.83 ± 0.35 ] mmol/L,t =6.47,P ＜ 0.01 ) and parathyroid hormone ( [ 639.47 ± 208.73 ] ng/L v.s.[ 409.91 ± 152.72 ] ng/L,t =5.27,P ＜ 0.01 ) levels of HDF group also decreased significantly.Comparison of the two blood purification methods indicated that the clearance effect of HP + HD on serum calcium,phosphorus and parathyroid hormone was significantly better than HDF( t =4.24 and t =7.24,P ＜ 0.01 ).Conclusion Both HDF and HD + HP could clear serum calcium,phosphorus and parathyroid hormone effectively,while the clearance effect of HD +HP is better than HDF.

ObjectiveTo investigate the influencing factors of preoperative fearful anxiety,and explore the effect of nursing intervention for the improvement of preoperative fearful anxiety. Methods500 cases of surgical patients in our hospital from January 2009 to January 2010 were chosen as the research objects.They were randomly divided into the control group and the observation group with 250 patients in each group.The control group was given routine preoperative nursing care.The observation group was given preoperative nursing intervention.The general information,surgery program,knowledge of surgical program,the patients' family situation and economic situation were taken for statistics.Their SAS score 30 minutes before the surgery was determined,and the influencing factors of preoperative fearful anxiety were analyzed. ResultsThe study showed that the influencing factors of fearful anxiety included:character,education background,family economic status,knowledge of the situation of surgery and other factors.The anxiety score 30 min before surgery was compared,the observation group was significantly lower than that of the control group.The difference between the two groups was significant. ConclusionsThe preoperative fearful anxiety was directly related to patients' own situation and level of medical services.Fully understanding of the situation before surgery and targeted preoperative nursing interventions can effectively reduce preoperative anxiety,and is conducive to the successful implementation of operation and postoperative rehabilitation.

Objective To investigate the psychological state and its correlation factors of family members of elderly cancer patients. Methods A total of 76 family members of elderly cancer patients were investigated with questionnaires with Zung's self-rating anxiety scale (SAS) and self-rating depression scale (SDS). Their psychological state and its correlation factors were analyzed. Results Incidence rate of anxiety of elderly cancer patients' family members was 52.63%, and incidence rate of depression was 46.05%. The mean standard score of SAS and SDS of elderly cancer patients' family members were both significantly higher than domestic norm. Difference of family member's gender, ways to pay health care fee, pain degree and disease condition led to different SAS and SDS score. Conclusions Family members of elderly cancer patients possessed different degree of psychological obstacle which related with multiple factors. Medical staff should not only think highly of patients' psychological state, but also their family members'. And meanwhile they should take corresponding strategy to reduce the incidence rate of anxiety and depression state in those family members.

Health history,clinical syndrome and imaging examination are key factors for early diagnosis of pancreatic trauma,while the effects of the test of the serum amylase for the diagnosis of pancreatic trauma remain unclear.Laparotomy plays an important role in the diagnosis of pancreatic trauma for patients,particularly urgent patients.The grading of pancreatic trauma functions as a bridge between the diagnosis and treatment of the pancreatic trauma.So far,the organ injury scale grading system proposed by the American Association for the Surgery of Trauma (AAST-OIS) provides guidelines for operative versus nonoperative management in solid organ injuries.Surgery is an important treatment method for pancreatic trauma according to injury control and surgical procedures grading principles.Recently,minimally invasive surgery has been involved in the diagnosis and treatment of the pancreatic trauma.

BACKGROUND: BO theory is introduced based on AO theory with the more attention to biological performance of fracture healing, which seriously promote the rapid development of bone plate. OBJECTIVE: To study the effect of the locking compression plate (LCP) by internal fixation on fracture healing of dog bilateral middle tibia. DESIGN, TIME AND SETTING: A contrast study was performed at the Traumatic Orthopaedics Tissue Engineering Laboratory of Southern Medical University from June 2006 to October 2007. MATERIALS: A total of 24 healthy adult dogs weighing 14.5-21.2 kg and of either gender were used to prepare bilateral middle tibia fracture models. LCP was made of 316L stainless steel and provided by Zhengtian Medical Apparatus Co., Ltd., Tianjin. Conventional AO stainless steel plate was provided by Mateshi (Shanghai) Medical Apparatus Trading Co., Ltd. METHODS: Right tibia was treated with internal fixation of LCP as the experimental group, and left tibia was treated with conventional AO plate as the control group. MAIN OUTCOME MEASURES: Samples were performed with X-ray examination, optic microscope, and microangiography, while microvessel image surface fraction was analyzed at 2, 4, and 6 weeks after operation. RESULTS: ① X-ray examination: The fractures healed well in both the experimental group and the control group, but a lot of bone calluses were found in the experimental group; while absorption and attenuation were found in bone cortex in the control group. ② Optic microscope: Bone absorption cavity was found in the control group, and structure of osteocytes was destroyed mostly. Bone absorption cavity was not found in the experimental group, and structure of plentiful osteocytes was intact. ③ Microangiography: A large area of ischemic region was found in bone cortex in the control group 2 weeks postoperatively and still observed 6 weeks postoperatively. A small area of ischemic region was found in the experimental group 2 weeks postoperatively; however, courser and distribution of microvessels were disorder. Six weeks later, the ischemic region disappeared generally, and courser of microvessels generally reached normal level. ④ Microvascular image surface fraction: At 2, 4, and 6 weeks postoperatively, the surface fraction in the experimental group was 1.78, 2.26, and 2.69 times as control group, and there was significant difference between them (P
