Objective To introduce a new technique in reconstruction of anterior cruciate ligament (ACL) by transplantation of autogenous hamstring and fixation with double crossbar (Rigidfix) under arthroscopy. Methods From July 2003 to Spetember 2005, 32 patients with ACL injury were treated with ACL reconstruction. Autogenous semitendinous and gracilis tendons were transplanted, fixed by double crossbar at the femoral end and an Intrafix screw in the tibial tunnel. Knee joint function and stability before and after operation as well as X-ray radiographs were evaluated according to the Lysholm scoring scale and International Knee Documentation Committee (IKDC) rating scale. The reliability of the fixation and its short term effect were analyzed. Results Twenty-eight patients were available for follow-up with duration from 6 to 28 months. The function of knee joint improved greatly. Four cases had unconscious positive findings in physical examination. The average Lysholm scores before and after opration were 53. 0?6. 3 and 90. 0?5. 2, respectively ( P

Objective:
To investigate the relationship of sleep duration and sleep quality with anxiety in the elderly aged 60 years and older in China.
Methods:
The elderly aged 60 years and older were selected from the China Short-term Health Effects of Air Pollution Study conducted between July 18, 2017 and February 7, 2018. Multivariate logistic regression models were used to analyze the association of sleep duration and sleep quality with anxiety.
Results:
A total of 3 897 elderly aged 60 years and older were included in the study. The age of the elderly was (73.4±8.0) years old. Among the elderly surveyed, 6.5

Objective:
To analyze influencing factors for depressive symptoms in the elderly aged 65 years and older in 8 longevity areas in China.
Methods:
We recruited 2 180 participants aged 65 years and older in 8 longevity areas from Healthy Aging and Biomarkers Cohort Study, a sub-cohort of the Chinese Longitudinal Healthy Longevity Survey in 2017. Multivariate logistic regression analysis was performed to evaluate the relationships of socio-demographic characteristics, behavioral lifestyle, chronic disease prevalence, functional status, family and social support with depressive symptoms in the elderly.
Results:
The detection rate of depression symptoms was 15.0

Objective:
To establish a prediction model for 6-year incidence risk of chronic kidney disease (CKD) in the elderly aged 65 years and older in China.
Methods:
In this prospective cohort study, we used the data of 3 742 participants collected during 2008/2009-2014 and during 2012-2017/2018 from Healthy Aging and Biomarkers Cohort Study, a sub-cohort of the Chinese Longitudinal Healthy Longevity Survey. Two follow up surveys for renal function were successfully conducted for 1 055 participants without CKD in baseline survey. Lasso method was used for the selection of risk factors. The risk prediction model of CKD was established by using Cox proportional hazards regression models and visualized through nomogram tool. Bootstrap method (1 000 resample) was used for internal validation, and the performance of the model was assessed by C-index and calibration curve.
Results:
The mean age of participants was (80.8±11.4) years. In 4 797 person years of follow up, CKD was found in 262 participants (24.8
