An evaluation scale of medical services quality was developed on the basis of "patients' experience". The questionnaires were developed by, among others, searching relevant literature, collecting well-established assessment scales, measuring patients' experience and satisfaction, brain-storming, literature analysis. Delphi method was adopted for expert consultation. Scale items were screened and revised. The key indexes were converted. Field surveys were conducted for testing the reliability and validity of the scale. Our modified evaluation scale for measuring medical services quality based on "patients' experience" included 6 dimensions (tangibility, reliability, responsiveness, assurance, empathy and continuity), and 50 items. The novel scale based on "patients' experience" may better serve the purpose of assessing medical services quality.

ObjectiveTo evaluate the effect of the timed “up and go” test (TUGT) on measuring functional mobility of stroke patients.MethodsNinety hemiparetic stroke patients participated in this study. The balance, gait speed and disability of patients were measured by Berg balance scale (BBS), maximal gait speed and functional independence measure (FIM) to find out the critical value of TUGT.ResultsA good relationship existed among TUGT and the BBS,gait speed and FIM (r=-0.926—-0.674,P<0.001).The percentage of independent walking of stroke patients whose TUGT scores <10s or>20s were 100% and 8.3%. The optimal cut off values of TUGT to predict the independent walking of patients were 15.2s, and in stroke group sensitivity and specificity of TUGT were 89.4% and 79.1%.Conclusion TUGT is a reliable instrument with adequate concurrent validity to measure the functional mobility of stroke patients.

Objective To prepare recombinant human epidermal growth factor (rhEGF) sustained-release microspheres and evaluate their morphology, rhEGF releasing activities and cell proliferation activity in vitro and compare difference of rhEGF sustained-release microspheres and rhEGF in facilitaring ulcer healing in diabetic rats. Methods (1) rhEGF sustained-release microspheres were prepared by the modified double emulsion method. Morphology of the microspheres was detected by transmission electron microscope and size distribution measured by laser granularity meter/Zeta electric potential meter. ELISA assays were applied to determine rhEGF releasing. (2)Proliferation of mouse fibroblasts was analyzed by MTr method. (3) Diabetic rat models were prepared and divided into four groups, ie, rhEGF sustained-release mierospheres group (Group A), rhEGF stock solution group (Group B), blank sustainedrelease mierospheres group (Group C) and PBS meustruum control group (Group D), which were given drug once a day. The wound healing rate was calculated by taking photographs at days 3,7,14 and 21. Skin specimens from the wound edge were harvested partially for observation of hydroxyproline (HYP) contents. Immunohistochemistry was employed to detect integrin 131 and keratin-19 and measure their positive staining area ratio. Results (1) The particle diameter of rhEGF sustained-release microspheres was 193.5 nm, with relative uniform particle diameter distribution. There showed no conglutination among rhEGF susrained-release microspheres, with good dispersibility. Releasing drug lasted for 24 hours and accorded with Higuchi release kinetic model. (2) Different concentrations of rhEGF sustained-release microspheres could promote the proliferation of mouse fibroblast, especially the concentration of 10 μg/L (P <0.05, compared with the control). (3) From the 7th day after treatment, Group A had the fastest wound healing rate, with statistical difference compared with other three groups (P < 0.05). Group A had higher HYP contents and positive area ratio of integrin β1 and keratin-19 than Group B. Conclusions rhEGF sustained-release microspheres prepared by the modified double emulsion method have uniform particle size and can last release for 24 hours. Compared with rhEGF stock solution, rhEGF sustained-release microspheres have faster and better ulcer healing and higher healing quality in diabetic rats.

Objective To observe the long term effects of arthroscopic knee debridement and reconstructing operation for treating osteoarthritis in patients with Kaschin-Beck disease. Methods Thirty-one cases of patients with Kaschin-Beck disease were followed for 6 years after operation of articular clearing by arthroscope. Index of pain, symptoms of self-evaluation, range of motion, walking distance, standing test by affected leg when bending at 30° or 60° were recorded and compared with the preoperative results. Results Twenty-four cases were followed up for 6 years. Six years after operation the pain index(3.38 ± 2.87) was dramatically decreased compared to that before operation (6.88 ± 1.45, t = 5.30, P ＜ 0.05). Patients symptoms markedly improved by subjective self-evaluation was 70.83% (17/24), the effective rate was 100% (24/24). The number of cases that could stand up when leg bending at 30° or 60° were 21,18 cases, respectively, compared with that of preoperative of 14, 11 cases, respectively, the difference was statistically significant(x2 = 5.17,4.27, all P ＜ 0.05). Six years after operation the walking distance(3 cases ＜ 1 km, 11 cases 1 - 5 km and 10 cases ＞ 5 km) were greatly improved compared to the results before operation (12 cases ＜ 1 km, 9 cases 1 - 5 km and 3 cases ＞ 5 km, U = 2.88, P ＜0.05). Six years after operation the knee activity[(132.25 ± 14.52)°] remained at the same level, compared with that of preoperative [(131 .58 ± 14.68) °], the difference was not statistically significant (t = 0.16, P ＞ 0.05) .Conclusions The method of arthroscopic joint debridement to cure Kaschin-Beck disease knee osteoarthritis can significantly reduce pain, improve function and walking distance, with more stable long-term satisfactory outcome.

ObjectiveTo investigate the relationship between strength of the paretic lower limb and motor function, balance, walking speed, ability of daily living (ADL) in hemiparetic stroke patients.Methods85 stroke subjects, who were able to walk in the study, were evaluated in the strength of the paretic lower limb, motor function, balance, walking speed and ADL with Motricity Index, Fugl-Meyer Assessment, Berg Balance Scale, 10 m walking speed test and Functional Independence Measure (FIM). The levels of association between them were examined with Pearson's correlation coefficients and with multiple linear regression analyses by using the stepwise method. ResultsStrengths of the paretic lower limb were significantly positive related to motor function, balance, walking speed and ADL (r=0.592-0.811,P<0.001). The paretic ankle dorsiflexors, knee extensors, hip flexors were important clinical factor to consider in determining motor function(R2=0.377,P<0.001), balance(R2=0.321,P<0.001)and walking speed(R2=0.173,P<0.001), ADL(R2=0.42,P<0.001). ConclusionStrengths of the paretic lower limb of stroke patients may play an important role in their motor function, balance, walking speed and ADL.

Objective To investigate the relationship between nasal colonization of Staphylococcus aureus(SA) and nosocomial infection in intensive care unit(ICU), and observe the therapeutic effect of Anerdian III in nasal decolonizaion. Methods Bacterial cultures were made by means of nasal swabs among inpatients whom the occurrence of nosocomial infection were observed.Patients with SA colonization were randomly divided into two groups:control and treatment.Control group were given regular treatment, and treatment group were administered Anerdian III in addition to regular treatment.Then the clearance rate of SA and the occurrence of nosocomial infection of two groups were observed. Results A total of 751 patients were enrolled, of whom 108(14.4%) were with nosocomial infection and 85(11.3%) with SA nasal colonization. Methicillin resistant Staphylococcus aureus ( MRSA ) was detected in 33 patients (4.4%).The nosocomial infection rate of patients with MRSA colonization was 51.5%, which was significantly higher than those in patients with other bacterial colonization(P<0.05).The SA clearance rate in treatment group was significantly higher than that in control group(81.4% vs.42.8%,P<0.05).The nosocomial infection rate in treatment group was significantly lower than that in control group ( 16 .3% vs. 40.5%,P <0.05).After decolonization treatment,the nosocomial infection rate of patients with MRSA colonization was significantly lower than that in control group(25.0% vs.76.5%,P <0.05). Conclusion The incidence rate of nosocomial infection in patients with MRSA nasal colonization is markedly increased in ICU, and the decolonization treatment by Anerdian III increases the clearance rate of nasal SA and decreases the incidence rate of nosocomial infection.
