BACKGROUND: Early rehabilitation following total knee replacement has arisen more attention. The aim of continuous passive joint motion is to recover knee function, prevent anchylosis, accelerate blood and synovia circulation, therefore, enhance tissue repair. OBJECTIVE: To evaluate the efficacy of continuous passive joint motion following total knee replacement. METHODS: Totally 48 patients, who underwent artificial total knee arthroplasty at the Department of Orthopedics, Center Hospital of Minhang District, Shanghai Ruikang Hospital Group and Department of Rehabilitation Medicine, 309~(th) Hospital of Chinese PLA between December 2007 and October 2009 were selected. The patients were randomly divided into the experimental and control groups, with 24 cases in each group. The isometric contraction of qudraceps muscles, combined with physical agent assistant, was performed prior to total knee replacement. Patients in the experimental group was received continuous passive joint motion training at day 2 after operation, with 5°-10°increasing per day. Patients in the control group were treated with conventional methods. The knee functional score, and visual analog scale (VAS) was performed to evaluate knee functions and pains, in addition, perimeter between two legs; and range of motion were measured. RESULTS AND CONCLUSION: The knee functional score, VAS, perimeter between two legs, and range of motion were similar prior to and after total knee replacement (P > 0.05). Compared to the control group, the knee functional score of the experimental group was dramatically increased at days 3 and weeks 2 after operation (P < 0.01), the VAS and perimeter between two legs were significantly declined (P < 0.01), the range of motion was obvious improved after replacement, with greater excellent rate (P < 0.01). There was no deep venous thrombosis or infections. The results demonstrated that early rehabilitation following knee replacement is conductive to easing pain, eliminating swelling, and enhancing knee stability.

Objective:To investigate the expression of estrogen receptor(ER) and interleukin-6(IL-6) in the intra-cardiac ganglia of rats and to identify the coexistence of these two proteins in the intra-cardiac ganglia.Methods:The double labeling techniques of immunocytochemical staining were conducted in the study.Results:There were three immunoreactively-labeled neurons in the ganglia.The ER-staining was showed brown in color,locating in the nucleus;IL-6 staining was showed red in color,locating in the cytoplasm;there were ER/ IL-6 double-labeled cells in same section,which accounted for about 20% to 30 %of the total single and double labeled neurons.Conclusion:ER and IL-6 can coexist in same rat intra-cardiac ganglia cells.Therefore,it provides morphological evidence for the theory about immune-neuro-endocrine network at the cellular level.

Objective:To study the expression and variance of interleukin-6(IL-6)and nerve growth factor positive neurons in the intrinsic cardiac ganglia of females that were intact,females that were ovariectomized,or ovariectomized females that were treated with 17?-estradiol.Methods:Immunohistochemical staining technique.Results:IL-6-IR and NGF-IR neurons were presented in the intrinsic cardiac ganglia of these groups,but the number of the IL-6-IR neurons increased remarkably and their expression increased obviously in the intracardiac ganglia of ovariectomized rats,while the number of the NGF-IR neurons decreased remarkably and their expression reduced obviously in the intracardiac ganglia of ovariectomized rats.Conclusion:IL-6 and NGF are present in rat intrinsic cardiac ganglionic cells and they are also influenced by estrogen,suggesting that 17?-estradiol may have the capacity to regulate the expression of IL-6 and NGF in intrinsic cardiac ganglia.

Objective To explore whether glycyrrhizin has protective effect on acute liver injury in mice by NF‐κB signaling pathway .Methods Totally 200 Kunming mice which the body weight were about 29 -30 g were chose and divided into 4 groups randomly ,50 cases in each group .The first group was the control group;the second group was acute liver injury group induced by CCl4 ;the third group was injected with Stronger Neo‐Minophagen C(SNMC) injection on the basis of second groups;the fourth group was treated with NF‐κB inhibitor (proDTC) on the basis of the third group .After 1 ,3 ,5 d treatment ,the serum expressing levels of ALT ,AST ,total bilirubin ,albumin of mice and prothrombin time were detected ,the Child‐Pugh score was calculated ,and the pathological observation was performed .Results The results showed that ,compared to the first group ,after CCl4 treatment ,the expressing levels of AST ,ALT ,total bilirubin and albumin ,the PT and Child Pugh score all were significantly increased(P<0 .05) , which indicated that the acute liver injury model induced by CCl4 was successfully established .After the treatment of SNMT (CCl4 +SNMT) in mice ,although the level of each index did not return to normal level ,with the extension of treatment time ,the level of each index was also significantly reduced (P<0 .05) .At the same time ,this effect could be reversed by NF‐κB inhibitor proDTC .Conclusion SNMT plays a significantly protective role in acute liver injury via regulating NF‐κB signaling pathway .

Objective To study the existence and variance of nerve growth factor positive neurons in the intrinsic cardiac ganglia of adult (3 months) and old (15 months) rats. Method Immunohistochemical staining technique. Results NGF positive neurons exist in the intrinsic cardiac ganglia of the adult and old rats, but these neurons decreased remarkably and NGF expression reduced obviously in the cardiac ganglia of old rats.Conclusions The find of NGF positive neurons in the posterior wall of atria provides morphologic evidence for the normal existence and the decreasing of NGF related with age in the cardiac ganglia.It also indicates that the degeneration of heart function may correlate closely to the expression of NGF.
