Objective To evaluate the effectiveness of Leprosy Elimination Compaigns (LEC) integrated with routine case- finding of leprosy in the high leprosy- epidemic areas in Yunnan, Guizhou and Sichuan Provinces. Methods Extensive health education of leprosy in the community, training of paramedical workers on leprosy, clue survey and contact survey were carried out to make diagnosis and provide treatment. Results A total of 122 new leprosy cases were detected in 6 high leprosy- epidemic counties through LEC in 1999 with a detection rate of 3.7/100 000, but in contrast, the annual number of newly detected leprosy cases was 67 cases with an average detection rate of 2/100 000 during the period of 3 years before LEC. Among the newly detected leprosy cases, about 47％ were leprosy household contacts. Conclusion LEC combined with routine activities of case finding can improve the detection of the back- log cases in the communities. In the high epidemic areas, especially in the remote and difficult- to- access areas, majority of leprosy cases can be detected through combining active and passive case- finding methods, providing extensive health education, improving leprosy services in skin clinic, leprosy contact and clue surveys.

Objective To analyze the detection modes of leprosy and their influencing factors and outcomes. Methods Based upon the nationwide registration of leprosy patients detected during 1981～ 1998, the profiles of these patients at detection were studied. Results The proportions of cases significantly correlated with calendar years in the detection by dermatologic clinic, contact check, clue survey and mass survey, showing a significant increases in percentage of cases detected through dermatologic clinic and contact check and decreases through clue survey and mass survey. Detection of leprosy cases through dermatologic clinic and voluntary reporting became the main modes of case－ finding during 1997－ 1998, accounting for 37.3％ and 28.6％ respectively, whereas contact check only accounted for 9.1％ . More MB patients were detected by voluntary reporting than PB, whereas detection by dermatologic clinic resulted in a significantly higher proportion (38.0％ ) in PB patients than in MB (33.5％ ). The voluntary reporting and clue survey resulted in higher proportions of detection in prefecture and county rural areas. In areas with good facilities of dermatologic services, significantly higher extent (75.9％ ) of cases were detected through dermatologic clinic, whereas the voluntary reporting and clue survey were main modes of case detection in endemic areas. A great majority of cases were confirmed by leprosy units even though they were detected by various modes. Only 6.5％ of leprosy cases were detected and consequently confirmed by doctors in dermatologic clinics. Conclusion This study emphasizes the importance of providing training on leprosy to the doctors in dermatologic clinics while continuously encouraging their involvement in leprosy control.

BACKGROUND: Total hip arthroplasy is an effective method to treat hip disease caused by ankylosing spondylitis. Long-term fol ow-up studies have shown that there have been hip function problems after total hip arthroplasy, and it stil lacks of perfect rehabilitation programs. OBJECTIVE: To systematical y review the influential factors for dysfunction after total hip arthroplasy in ankylosing spondylitis patients. METHODS: The first and second authors retrieved PubMed and Sciencedirect Databases, CNKI, and Wanfang digital database for relevant articles published from January 1970 to July 2015. The key words were “arthroplasty, replacement, hip, spondylitis, ankylosing, function”. Final y, relevant articles were included. RESULTS AND CONCLUSION: A total of 40 articles were summarized, including 8 Chinese articles and 32 English articles. After total hip arthroplasy, hip function problems were mainly associated with patient’s factors, disease, surgery, prosthesis, postoperative recovery and postoperative complications. Avoiding above relevant factors can improve joint function after total hip arthroplasy for ankylosing spondylitis patients, and improve patient’s quality of life.

Objective To explore the effect of contract learning on rehabilitation training to patients with stroke . Methods According to the random number table, 120 stroke patients were randomly divided in equal number into control group and observation group. The patients in the control group were treated with conventional nursing during hospitalization and health guidance during follow-up. The patients in the observation group were given rehabilitation training according to contracted learning during the period of hospitalization and follow-up. The time was 6 months. The quality of life was compared between the two groups of patients before and after the intervention, 1 months after discharge, 6 months after discharge. Results After six months of intervention, the 7 dimensions of quality of life, including daily life ability, hand function, mobility, strength, emotion, communication and participation in the intervention group were significantly better than those of the control group (P<0.001). The 6 dimensions of quality of life, including daily life ability, hand function, mobility, strength, emotion, and communication of the control group were significantly better than before the intervention (P<0.001). Conclusion For stroke patients, the rehabilitation training under the learning contract can improve the effect of rehabilitation training so as to improve the quality of life and the prognosis.

Objective To evaluate the effect of bleaching agents on the color of indirect and direct composite resins.Methods Five resin composite materials were tested in this in vitro study.The five composites were as follow:two indirect composite resins (Adoro SR,Ceramage) and three direct composite resins (Filtek Z350,Clearfil Majesty Esthetic,and Gradia Direct Anterior).For each material,twenty disk-shaped specimens were prepared and randomly divided into five groups according to the color parameters of specimens before bleaching treatment.The composite resin specimens were treated by one of five sample solutions which were at-home bleaching agents (10％ and 15％ carbarmide peroxide),in-office bleaching agents (38％ H2O2 and 35％ H2O2) and deionized water (control group).The color parameters of specimens were measured by spectrophotometer at baseline and after bleaching treatments.The color differences (ΔE values) between baseline and post-treatments were calculated.The data of color differences were evaluated statistically using two-way analysis with a significance level of 0.05.Results The color changes of the resin composites were less than 2.0 after bleaching agent treatment,therefore were not perceptible.Slight increase of L* values and decrease of C*ab values in color parameters of specimens were observed.There were statistically significant differences in ΔE values for different bleaching treatments and resin materials(P=0.001).Conclusions The bleaching agents did not affect the color of indirect and direct composite resins tested.

Objective. To undertake the pilot experiments of prevention of disability (POD) in 14 different geographical areas to serve as examples for future development of rehabilitation work in China and in Asia. Methods. According to the principles and national criterion, 27 000 people aflected by leprosy were selected and assessed using disability record forms at beginning and followed up regularly for observing changes of different indica-tors. Results. A total of 197 neuritis cases were detected and treated with prednisolone out of 1 407 new or active cas-es. Self-care training of eyes, hands and feet were conducted for 10 500 disabled people affected by leprosy. Compre-hensive therapy was given to 1 804 cases having complicated ulcers of which 1 055 cases have got their ulcers healed.Out of 706 prostheses, 613 were given to patients with satisfactory results. Surgical treatment was given to 269 cases and 251 have shown good progress. Conclusion. Most of patients have got benefit from the project in function or appearance which is very helpful for their going back to the society and agreed by foreign experts during the final evaluation. The experiences from the pro-ject can be implemented in the whole country.

Objective: The aim of the study is to validate whether the Recognition Of Stroke In the Emergency Room (ROSIER) scale can be used by general practitioners (GPs) in an emergency medical service (EMS) protocol to transfer stroke patients from primary care center to advanced hospital with acute stroke center. Methods: GPs prospectively performed the ROSIER scale and the Cincinnati Prehospital Stroke Scale (CPSS) on suspected stroke patients as a transfer protocol. All patients were immediately transferred to the Level-II hospital for further treatment. Results: 468 of the 512 suspected stroke patients met the inclusion criteria in this study. The ROSIER scale showed a diagnostic sensitivity of 83.13% (95% confidence intervals [CI] 79.74-86.52%) and specificity of 80.88% (95% CI 77.32- 84.44%). The CPSS showed a diagnostic sensitivity of 78.01% (95% CI 74.26-81.76%) and specificity of 70.59% (95% CI 66.46-74.72%). The Kappa statistic value of the ROSIER scale and the CPSS were 0.601 and 0.454, respectively. The area under the curve (AUC) of ROSIER scale was large than the CPSS (AUC 0.855 vs. 0.791). However, the difference was not significantly different. Conclusions: This study suggest that ROSIER and CPSS could be used in an EMS protocol to transfer stroke patients from a primary care center to an advanced hospital offering thrombolysis service
