It is generally known that postoperative pain can cause many adverse clinical effects on the patients of orthopaedic surgery such as lack of exercises of the involved limb,atrophy of the related muscles,anchylosis,osteoparosis,et al,which will ultimately affect the patient's final recovery and living quality.This paper introduces some recent advanced theories about the orthopaedic postoperative pain diagnosis,evaluation and various kinds of treatments hoping to achieve more effective perioperative analgesia in orthopaedic surgery.

Objective To investigate the clinical value of Holter monitor(DCG) in the diagnosis and treatment of dilated cardiomyopathy (DCM).Methods According to NT-proBNP ＞ 2 000pg/mL,left ventricular ejection fraction (LVEF) ≤40％,New York Heart Association (NYHA) rated Ⅲ-Ⅳ,67 patients with DCM were divided into the high risk group and nonhigh risk group.All kinds of arrhythmia patients proportion was compared between the two groups,in order to understand the risk factors of DCM and arrhythmias.Results In high risk group,18 cases had ventricular tachycardia,the incidence rate was 66.7％,which was significantly higher than that of non high risk group (2 cases,5.0％) (x2 =29.271,P ＜ 0.01).While other arrhythmia,atrial premature beats,single premature ventricular contraction,atrial fibrillation and so on,had no statistical difference (P ＞ 0.05).Conclusion The DCM patients with various types of arrhythmia,ventricular tachycardia in patients directly influence the severity and prognosis,Holter monitor has an irreplaceable role.

ObjectiveThe purpose of this research was to investigate functional connectivity of 16-channel electroencephalograph(EEG) in δ frequency band based on Granger causality analysis.MethodsThe experimental data was recorded at a sampling rate of 200 Hz from temporal lobe epilepsy (TLE) patients(6 left and 3 right TLE,and 9 normals as control group.Ten of EEG segments of 20 s length for three different states:epileptiform discharges (ED) state in interictal durations,non-ED state for TLE patients,and control state for the normal.The δ band components (1～4 Hz) were filtered from EEGs.The functional connection values Iδ between two EEG δ components were calculated separately by Granger causality analysis.The two EEG components were from inferoposterior temporal lobe (left:T5,right:T6) to frontal lobe (Fp1,Fp2,F3,F4,and parietal lobe (C3,C4) for three states.ResultsThe Iδ values for ED state was 0.1323±0.0329～0.1670±0.028 9,which was significantly higher than that of non-ED state (0.0300±0.0130～0.0420±0.0072) (P＜0.05).The Iδ values for the control group (0.0153±0.0028～0.0193±0.0057) was much lower than that of ED state (P＜0.01),and no obvious distinctions were observed compared with non-ED state at P=0.05 level.ConclusionThere is a stronger connection of EEG' s δ bands from the inferoposterior temporal lobe to frontal and parietal lobe for the ED state,and the over-discharges transmission is from inferoposterior temporal lobe to other brain regions.There is a weaker connection from the top temporal lobe to frontal and parietal lobe for non-ED state and control group,and the onset zones is not inferoposterior temporal lobe.

Objective To study the anatomical feature s of the retroperitoneal cavity around kidney under laparoscope and to provide ana tomical guidance for laparoscopic surgery. Methods Lapar oscopic renal and ureteral operations were performed on 241 patients (145 men an d 96 women; age range,16-75 years;mean age,45.3 years).Through the videos and ph otographs of these operations,the anatomical features were analyzed.The atlas wa s drawn and surgical access was designed. Results Under laparoscope lateral conal fascia continues from the fascia of quadratus lumborum at its lateral border.This fascia covers posterior lamella of Gerota’s fascia and fuses into transversalis fascia beneath peritoneum. Fusion fascia lies befor e anterior lamella of Gerota’s fascia. It extends laterally and disappears grad ually to the lateral reflexion of peritoneum.The plane between fusion fascia and anterior lamella of Gerota's fascia, the plane between lateral conal fascia and posterior lamella of Gerota’s fascia, the plane before the quadratus lumborum and psoas major, are all vessel-free planes.Lateral border of colon,peritoneum and fusion fascia form a triangle lateral to colon.Fusion fascia,lateral conal f ascia and Gerota’s fascia form a vessel-free triangle. Conclusions Dissection through the vessel-free planes prevents laparoscopic op erations from bleeding and organ injury.Full understanding of the laparoscopic a natomical features of the retroperitoneal cavity around kidney provides the anat omic theoretical basis for laparoscopic operations.
