A single drug or a method may not achieve the best result for the management post-operative pain, so multimodal analgesia is proposed as a new analgesic concept in recent years. This article describes the mechanism of postoperative pain, some of the factors affecting postoperative pain and the importance of the treatment of postoperative pain after surgery. It also introduces a variety of analgesic drugs and methods commonly used as multimodal analgesia in postoperative pain treatment in orthopaedic. Foreground of the research is prospected as well.

There should be two systems studying from complex human system:pleurodiaphragmatic interspace systems of narrow-meaning and broad-meaning.The narrow-meaning one's connotation:a vertical hidden pleurodiaphragmatic interspace,the structure of 2 horizontal pleurodiaphragmatic interspace;the broad-meaning one's connotation:the relation structure of ① 9 fault horizontal pleurodiaphragmatic interspaces,② 9 straight vertical pleurodiaphragmatic interspaces,③pleurodiaphragmatic interspaces of 18 horizontal-wheel cross sections.Tri-jiao is the human's giant system of Qi function of essential Qi,deciding the functional level of pleurodiaphragmatic interspace.The large system of functional level governs all the sub-systems.All levels of systems control the relation net knob of intersected pleurodiaphragmatic interspaces;the relation net knob corresponds to unit deciding the special structures of all systems of pleurodiaphragmatic interspaces.The systemic pleurodiaphragmatic interspace theory is based on the classic subject of tri-jiao—the door of pleurodiaphragmatic interspace.Mr.Xue Shengbai's principle has outstanding initial achievement in analyzing the subject,opening the secret gate of tri-jiao,guiding the sealed and blurred pleurodiaphragmatic interspace theory into complex systemic research,activating the horizontal confusing pleurodiaphragmatic interspace into dimensional structural space,promoting it stand up and walk and be alive,also bringing it into the big system of tri-jiao Qi function,making the integrated constant move theory connected in levels of governing,abiding,being through,collateral and simplicity,finally falling down the spot of effective clinical treatment,with decoction corresponding to sign,developing creative modern model of TCM systemic pleurodiaphragmatic interspace theory.

Apply systemic complex study method to make multi-level and visual field study on Pleurodiaphragmatic Interspace Principle of febrile disease,aiming to expose occurrence principle of Pleurodiaphragmatic Interspace syndrome science,its form position,physiological function and pathological mechanism,syndrome state as well.Its syndrome types;explore its connotation in broad and narrow meanings,define the relation structure and functional level of Pleurodiaphragmatic Interspace and Shaoyang,half superficial and inner of triple energizer,offer reference and effective resource for modern clinical infectious disease,acute contagion,type A H1N1,esp.the treatment based on differentiation of signs of "latent pathogeny in Pleurodiaphragmatic Interspace",one of wet hot febrile and pestilence diseases in Jiangnan,Lingnan and Liangguang region.

Fasting plasma gastrin levels were found to be elevated in 35 cases of hyperthyroidism (265.17?143.17 pg / ml) as-compared with the normal controls (68.30?28.00 pg / ml). The elevated gastrin levels were obviously lowered after the thyroid function was normalized by treatment (115.54?45.86 pg / ml, P

The serum soluble interleukin 2 receptor(sIL—2R)in 39 patients with malignant tumour of degestive system wasemeasured using by sandwith ELISA with monoclonal and polycional antibodies technigue.The results show the level of sIL—2R was obvious higher than level of sIL—2R of the controls(P

Objective To evaluate the effect of ketamine and elonidine on P2X4R mRNA expression in the spinal cord in a rat model of neuropathic pain.Methods Eighty male SD rats weighing 180-220 g were randomly divided inte 5 groups (n = 16 each): sham operation group (group S),neuropathic pain group (group NP),ketamine group (group K),clonidine group (group CL) and ketamine + clonidine group (group KC).The animals were anesthetized with intraperitoneal chloral hydrate 400 mg/kg.The right sciatic nerve was exposed and four ligatures were placed on the sciatic nerve at 1 mm interval.In group S,the right sciatic nerve was exposed but not ligated,and in the other groups four ligatures were placed around the right sciatic nerve (chronic constrictive injury,CCI) as described by Bennett.The animals were injected intraperitoneally with ketamine 10 mg/kg,clonidine 1 mg/kg,and ketamine 5 mg/kg + clonidine 0.5 mg/kg in normal saline 2 ml in group K,CL and KC respectively,while normal saline 2 ml in group S and NP at 3-21 d after CCI.Mechanical and thermal pain threshold were measured by paw withdrawal latencies to run Frey hair and radiant heat stimulation at 1 d before and 3,7,14,21 d after CCI.Four animals were killed at 1 d before (baseline) and 7,14 and 21 d after CCI following the measurement of pain threshold in each group and the L4.5 segments of the spinal cord were removed for determination of P2X4 R mRNA expression by RT-PCR.Results There was no significant change in thermal and mechanical paln threshold and P2X4 R mRNA expression in the spinal cord after CCI in group S ( P > 0.05),while thermal and mechanical pain threshold was reduced,and P2X4 R mRNA expression was up-regulated in the other four groups as compared with the baseline values (P < 0.05 ).Thermal and mechanical pain threshold was significantly higher and P2X4 R mRNA expression in the spinal cord lower after CCI in group K,CL and KC than in group NP ( P < 0.05 ).Thermal and mechanical pain threshold was significantly higher and P2X4 R mRNA expression lower after CCI in group KC than in group K ( P < 0.05),but no significant difference was found in the above parameters between group CL and K ( P > 0.05).Conclusion Both ketamine and clonidine can alleviate neuropathic pain via down-regulating the expression of P2X4 R mRNA in the spinal cord in a rat model of neuropathic pain.

Objective To investigate the predisposing factors and fungal characteristics of nosocomial fungal infection (NFI) in patients with chronic kidney disease (CKD). Methods The fungal characteristics and laboratory indices were analyzed in patients with and without NFI secondary to CKD. Results The most common infection site of NFI in 65 cases patients with CKD was urinary tract (25 man-times, 38.46%), and the second common site was digestive tract (20 man-times, 30.77%). The most common pathogenic fungus was Candida albicans (68.49%), followed by Candida tropicalis (17.81%). The sensitivity of Candida albicans to fluconazol was 90%. The predisposing factors included prolonged length of stay, anaemia, malnutrition, hypogammaglobulinemia, mass proteinuria, renal insufficiency, and the use of large dose of broad spectrum antibiotics, prednisone and cytoxan. Conclusion CKD may predispose to NFI, and the most common fungus is Candida albicans,so the predisposing factors should be controlled so as to prevent NFI among patients with CKD.

Objective To investigate the effects of ketamine preconditioning on the expression of induced nitric oxide synthase(iNOS)mRNA after myocardial ischemia-reperfusion injury induced by cardiopulmonary bypass(CPB)in patients with congenital heart disease(CHD).Methods Thirty-six patients with atrial or ventrieular septal defect were randomly allocated to 3 groups(n=12):control group and ketamine preconditioning group(K1 group,K2 group).Ketamine 0.5 mg/kg and 1.0 mg/kg,were injected at the time of sternum splitted,aorta intubated and before 5 minutes of aorta clamped off intravenously.Collected the myocardium at the time of superior vena cava intubated(T1),30 minutes after aorta clamped on(T2)and 30 minutes after aorta clamped off(T3).Detected the value of iNOS mRNA in myocardium by one-step real time fluorescence quantitative RT-PCR.Results The levels of iNOS mRNA were significantly increased at T2 and T3 as compared with T1 in the three groups,and were significantly lower both in K1 group(2.33±0.31,3.76±0.61)and K2 group(1.92±0.12,3.12±0.39)than those in control group(2.85±0.48,4.49±0.86)(P＜0.01 or ＜0.05).Furthermore,they were lower in K2 group than those in K1 group(P＜0.05).Conclusion Ketamine can significantly decrease iNOS mRNA in myocardium,and decrease the plasma marker of cardiac muscle injury,it shows dose dependent.
