ABSTRACT
OBJECTIVE@#To explore the association between depressive symptoms and the risks of rapid decline in renal function and chronic kidney disease (CKD) in middle-aged and elderly with normal kidney function.@*METHODS@#The residents aged 40- 75 years with eGFR≥60 mL·min-1·1.73 m-2 without proteinuria in Lanzhou region, who participated in the "REACTION" study carried out in 2011, were selected and followed up in 2014. A total of 4961 individuals with complete and qualified data from the two surveys were included in the subsequent analysis. Based on PHQ-9 questionnaire scores, the baseline population was divided into two groups with and without depressive symptoms. Cox proportional hazard analysis was used to compare the incidences of rapid renal function decline and CKD between the two groups and study the association of depressive symptoms with the risk of these renal conditions.@*RESULTS@#PHQ-9 questionnaire scores were not found to correlate with baseline SCr, ALB, UACR or eGFR levels among the participarts (P>0.05). After a mean follow-up time of 3.4±0.6 years, 33.9% of the participants with depressive symptoms at baseline experienced a rapid decline in renal function and 3.6% progressed to CKD. During the follow-up, the incidence of rapid decline in renal function and the risk of developing CKD were not found to correlate with depressive symptoms in these participants (P>0.05) regardless of the type of the depressive syndromes.@*CONCLUSION@#Depressive symptoms are not associated with the risks of rapid renal function decline or progression to CKD in middle-aged and elderly with normal kidney function.

ABSTRACT
BACKGROUND AND OBJECTIVES: Postoperative analgesia is crucial for early functional excise after total knee arthroplasty. To investigate the clinical efficacy of ultrasound and nerve stimulator guided continuous femoral nerve block analgesia after total knee arthroplasty. METHODS: 46 patients with ASA grade I-III who underwent total knee arthroplasty received postoperative analgesia from October 2012 to January 2013. In 22 patients, ultrasound and nerve stimulator guided continuous femoral nerve block were performed for analgesia (CFNB group); in 24 patients, epidural analgesia was done (PCEA group). The analgesic effects, side effects, articular recovery and complications were compared between two groups. RESULTS: At 6 h and 12 h after surgery, the knee pain score (VAS score) during functional tests after active exercise and after passive excise in CFNB were significantly reduced when compared with PCEA group. The amount of parecoxib used in CFNB patients was significantly reduced when compared with PCEA group. At 48 h after surgery, the muscle strength grade in CFNB group was significantly higher, and the time to ambulatory activity was shorter than those in PCEA group. The incidence of nausea and vomiting in CFNB patients was significantly reduced when compared with PCEA group. CONCLUSION: Ultrasound and nerve stimulator guided continuous femoral nerve block provide better analgesia at 6 h and 12 h, demonstrated by RVAS and PVAS. The amount of parecoxib also reduces, the incidence of nausea and vomiting decreased, the influence on muscle strength is compromised and patients can perform ambulatory activity under this condition. .

<p><b>OBJECTIVE</b>To explore the mechanism of Shangke Jiegu Tablet (SJT)in repairing the mandibular defect.</p><p><b>METHODS</b>Totally 72 healthy male New Zealand rabbits were randomly divided into the normal control group (n = 24), the model group (n = 24), and the SJT group (n = 24). Then the mandibular defect model was established. Animals in the normal control group and the model group were fed with normal forage, while those in the SJT group were fed with SJT forage. On the day 7, 14, 28, and 56 after model establishment, 6 rabbits were killed in each group. The bone was collected from the mandibular defect. The gene expressions of osteoprotegerin (OPG) and osteoprotegerin ligand (OPGL) were detected by means of RT-PCR. The positive dyeing strength and area of the bone tissue were detected by means of immunohistochemical technique.</p><p><b>RESULTS</b>Compared with the normal control group, the degree of OPGmRNA expression was remarkably up-regulated on day 7 after model establishment (P < 0.05) and the degree of OPGLmRNA expression was remarkably up-regulated on day 14 after model establishment (P < 0.05) in the model group. Compared with the model group, the degree of OPGmRNA expression was remarkably up-regulated (P < 0.05), and the positive dyeing strength and area of bone tissue were stronger and broader on day 14, 28, and 56 after model establishment in the SJT group. The degree of OPGLmRNA expression was remarkably down-regulated (P < 0.05), and the positive dyeing strength and area of bone tissue were weaker and smaller on day 14 after model establishment in the SJT group. The ratio of OPGmRNA/OPGLmRNA was remarkably up-regulated on day 14, 28, and 56 after model establishment (P < 0.05).</p><p><b>CONCLUSION</b>The effect mechanism of promoting mandibular defect repairing by SJT may be correlated to regulating the expressions of OPGmRNA and OPGLmRNA.</p>
