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 determine the intra-and inter-tester reliability of a dynamometer in assessment of knee joint position senses (JPS).Methods Sixteen healthy volunteers (intra-rater N =6,inter-rater N =10) were examined with regard to intra-and inter-tester reliability of knee JPS by using Biodex System 3 dynamometer,measured by passive replication test,with subjects passively returning to the initial positions at 30°,45° and 60° knee flexion.The absolute error (AE) angle was recorded.Both intra-and inter-tester reliability studies involved two testers.Results The intra-tester reliability of the AE were moderate reliable at 30°,45°and 60° knee flexion,and the values of intra-class correlation coefficients (ICC) were 0.728,0.780 and 0.807,respectively.The values of Pearson's correlation coefficients for inter-tester reliability were 0.676,0.610 and 0.705,respectively (P ＜ 0.05).There was no significant difference between the AE values of dominance and non-dominant knees,test and retest,and in the AE values of 30°,45°and 60° knee flexion (P ＞ 0.05).The 95％ confidence upper limits of all subjects' AE values were less than 3°.Conclusion The major findings of this study suggest that the test-retest reliability of the knee JPS were moderate using Biodex System 3 dynamometer,and selecting a target angle of passive replication test can achieve the same purpose in 30° to 60°knee flexion.The clinical significance should be taken into consideration when the AE changes were greater than 3 degrees.

OBJECTIVE To discuss the mycology characteristic of two strains of Rhodotorula glutinis causing infection in ICU,and conduct molecular biological identification and antifungal agent sensitivity experiment.METHODS The methods used included conventional mycology identification and sequencing the ITS region of strains,and the in vitro antifungal agent sensitivity experiment were done by glutinis liquid-based dilution method(M27-A).RESULTS The two strains of R.glutinis were confirmed after mycology identification and sequenced the ITS region of strains.They were both sensitive to amphotericin B and 5-flucytosine,and insensitive to fluconazole,itraconazole and voriconazole.CONCLUSIONS The reasons causing Rh.glutinis infection include catheter related infections,(total parenteral nutrition TPN) and immunosuppressives.Using amphotericin B and removing intravenous catheter can be the first choices in the treatment of Rh.glutinis infection.Azole shows insensitive to Rh.glutinis in the in vitro antifungal agent sensitivity experiment,therefore it should be used very carefully.

Objective To study the relationship of intestine permeability with post hepatitis cirrhosis. Methods Serum DAO levels were measured by Holt method and lactulose/mannitol absorption tests were performed in 96 patients (Child A, n =11; Child B, n =37; Child C n =48) with post hepatitis cirrhosis and 49 healthy control subjects to evaluate the intestine structure and function of the patients. Lactulose and mannitol levels in 5 hours urine were determined by gaschromatographic assay. Results DAO activity and lactulose/mannitol ratio were higher in each patient group than those in normal control group (DAO Child A 4.68?0.97, Child B 6.05?1.02, Child C 7.80?1.34 vs 3.98?0.93, P

Objective To observe and compare the functional outcomes of early rehabilitation of persons who received primary bilateral or unilateral total knee arthroplasty (TKA).Methods Sixty-eight subjects were divided into a unilateral TKA group (36 cases) and a bilateral TKA group (32cases).All received the same professional rehabilitation program during an average postoperative hospital stay of (15.00 ± 3.71 ) days.At discharge,a visual analogue scale (VAS) was used to rate pain.Active range of motion (AROM) of the involved knee,knee injury and an osteoarthritis outcome score (KOOS) were also assessed.The KOOS and knee society score (KSS) were evaluated at follow-up about 11 months later.Results There was no significant difference between the two groups in any assessment at discharge,nor in the KOOS and KSS-Ⅰ assessments at follow-up.The KOOS of both groups at follow-up had improved significantly compared with that at discharge.The KSS-Ⅱ results in the bilateral group were slightly better than those in the unilateral group at follow-up,and that difference was significant.Conclusions Bilateral TKA patients and unilateral TKA patients had the same clinical outcomes after early postoperative rehabilitation,but the functional outcomes of bilateral TKA patients were better than those of unilateral TKA patients a year later.

Objective To explore the biomechanical mechanism of non-erosive reflux disease(NERD).MethodsFrom October 4,2014 to September 30,2015,17 NERD patients and 17 healthy controls were recruited from the outpatients department of China-Japan Friendship Hospital.The cross-sectional area(CSA), intra-balloon pressure (IBP)and compliance(Δv/Δp)of each were measured by endoscopy in combination with EndoFlip.ResultsWith the increase of balloon volume,the compliance of gastroesophageal junction in NERD group was significantly higher than that of control group(P<0.01) while the cross sectional area and intra-balloon pressure were similar.Conclusions Increased compliance of the gastroesophageal junction may be involved in the pathogenesis of non-erosive reflux disease.

OBJECTIVETo investigate phytoestrogenic effects of ferulic acid in ER-positive T47D and ER-negative MDA-MB231 cells in culture.

METHODT47D and MDA-MB231 human breast cancer cells were treated with ferulic acid and examined cell proliferation by means of MTT assay. Cell cycle distribution, ERalpha and ERbeta expression were treated by flow cytometer. The pS2 mRNA expressions were detected by real-time fluorescence quantitative PCR.

RESULTThe proliferations were enhanced significantly by treatment with ferulic acid on T47D cells and the proliferation effects were inhibited by adding Faslodex (1 x 10(-8) mol x L(-1)). However, there was no significant difference on the proliferation in MDA-MB-231 cells compared with solvent control group by both treatment with ferulic acid and co-treatment with Faslodex (1 x 10(-8) mol x L(-1)). Ferulic acid stimulated the amount of T47D cells in phase S and proliferation index increased significantly. The effects were inhibited by treatment with Faslodex (1 x 10(-8) mol x L(-1)), and the amount of cells in phase S and proliferation index decreased, the amount of cells in G0/G1 phase increased, cell cycle of T47D was arrested in G0/G1 phase. Ferulic acid up-regulated pS2 mRNA expressions and increased the level of ERalpha protein expression in T47D cells. Ferulic acid did not show remarkable effect to the level of ERbeta protein expression in T47D cells.

CONCLUSIONFerulic acid possessed phytoestrogenic effect by up-regulating pS2 gene expression and the receptor subtype of ERalpha.
