ObjectiveTo explore the relationship between the motor cognitive ability and the incidence of fall in the aged people. MethodsAccording to the fall experience within a year, 91 aged people were divided into 2 groups: fall group and non-fall group. They were tested using the Timed Up and Go Test (TUGT) with the eyes opening or closing. The anticipated time, actual time and the difference were recorded. ResultsThere were significant differences between these 2 groups in the eye-closed anticipated time, actual time, the difference of eye-open anticipated time and eye-closed anticipated time, the difference of eye-open anticipated time and actual time (P<0.05). ConclusionThe motor cognitive ability of the falled elderly more depends on their vision. The motor cognitive disability is one of the factors resulted in fall in aged people.

OBJECTIVETo explore the inhibition and molecular mechanism of icaritin (ICT) combined doxorubicin (DOX) on human osteosarcoma MG-63 cells in vitro.

METHODSThe control group, ICT groups (10, 20, 40, 80, and 160 µmol/L), DOX groups (1, 2, 4, 8, and 16 µg/mL), and combination groups (20 µmol/ L ICT +1 µg/mL DOX, 20 µmol/L ICT +2 µg/mL DOX, 20 µmol/L ICT +4 µg/mL DOX, 40 µmol/L ICT +1 µg/mL DOX, 40 µmol/L ICT +2 µg/mL DOX, 40 µmol/L ICT +4 µg/mL DOX, 80 µmol/L ICT +1 µg/mL DOX, 80 µmol/L ICT +2 µg/mL DOX, 80 µmol/L ICT +4 µg/mL DOX) were set up. Human osteosarcoma MG-63 cells were respectively cultured and their effects on morphological changes were observed using inverted phase contrast microscope after 24-and 48-h intervention. The cell proliferation inhibition rate of each group was de- termined using CCK-8, and IC50 calculated. The MG-63 apoptosis rate was detected using Annexin V-FITC/ PI double dye flow cytometry. Expression levels of bcl-2, caspase-3, and p21 were detected using RT-PCR.

RESULTSICT and DOX could obviously inhibit the proliferation of MG-63 cell. Along with ICT concentration increasing from 10 µmol/L to 160 µmol/L, the cell proliferation inhibition rate also increased gradually from 9.67% ± 3.62% to 89.18% ± 9.66%. The IC50 was 46.93 µmol/L and 3.87 µg/mL respectively. ICT and DOX could cause either early or late stage apoptosis, down-regulate Bcl-2 gene expression, and up-regulate gene expressions of Caspase-3 and p21 respectively (P < 0.05). Aforesaid changes were more obviously seen in combination groups than in lCT groups and DOX groups (P < 0.05).

CONCLUSIONCT combined DOX had additive or synergistic inhibition effect for the proliferation of osteosarcoma MG-63 cells, which might be related with regulating gene expressions of bcl-2, caspase-3, and p21.

OBJECTIVETo explore the clinical roles of Jiawei Shentong Zhuyu Decoction (JSZD) in preventing the occurrence of failed back surgery syndrome (FBSS), and to observe its effect on serum tumor necrosis factor-alpha (TNF-alpha).

METHODSTotally 100 patients prepared for surgical operation due to lumbar intervertebral disc herniation were randomly assigned to the treatment group and the control group according to random number table, 50 cases in each group. Patients in the treatment group additionally took JSZD, one dose per day, taken in two portions, once in the morning and once in the evening. Those in the control group took Celecoxib Capsule (200 mg each time, once per day) and Mecobalamin Tablet (0.5 mg each time, 3 times per day). They only took Mecobalamin Tablet from the 11th day. All patients were treated for 30 days. Japanese Orthopaedic Association (JOA) score was performed before treatment, at week 1, after treatment, at 6 months of followed-ups, and at 12 months of followed-ups. And the levels of TNF-alpha in the peripheral blood were observed before treatment and at one month after treatment.

RESULTSTotally 93 patients completed the followed-up study. The JOA scores were improved after treatment, at 6 and 12 months of followed-ups (P < 0.05, P < 0.01). The JOA score at 6 months of followed-ups was superior in the treatment group to that of the control group (P < 0.05). Five patients (accounting for 10.6%) suffered from FBSS in the treatment group, while 9 (accounting for 19.6%) suffered from FBSS in the control group. The treatment group was superior to the control group (P < 0.05). The TNFalpha level was improved after treatment in the two groups. Of them, the improvement of TNF-alpha in the treatment group was better than that of the control group (P < 0.05).

CONCLUSIONThe application of JSZD was effective for preventing the occurrence of FBSS, and improved the serum TNF-alpha level.

OBJECTIVETo adopt a criterion summarized in long-term practice to judge the immune status of recurrent aphthous ulceration (RAU) patients, and to analyze its rationality and feasibility.

METHODS60 cases were included, whose clinical information, such as age, sex, constitution status, history of system diseases and severity of ulceration were collected. The subjective judgement results of the immune status were obtained according to the criterion summarized in clinical practice. At the same time, peripheral blood parameters about immune function were examined in order to obtain the objective examination results of the immune status. With the examination result as the gold standard, the rationality of the criterion was estimated through its sensitivity and specificity.

RESULTSAccording to subjective judgment, there were 86.67% cases with abnormal immune status (28.33% cases with elevated immune status, and 58.33% cases with reduced immune status). According to objective examination, there were 93.33% cases with abnormal immune status (23.33% cases with elevated immune status, and 70.00% cases with reduced immune status. Sensitivity and specificity were 89.29% and 50.00% when the criterion was used to judge immune abnormality, 42.86% and 76.09% when the criterion was used to judge immune elevation, and 64.29% and 55.56% when the criterion was used to judge immune reduction.

CONCLUSIONIt is of some rationality and feasibility to judge the immune status according to the criterion based on clinical information, and the criterion can be used in small clinics.

OBJECTIVETo study on the effect of acteoside on learning and memory of dementia mice.

METHODMice were orally administered with acteoside for 10 days. Scopolamine was used to establish the acquired learning disability in mice. Their learning and memory were detected with a behavioral experiment (step-down test). After the behavior test, corticocerebral and hippocampus tissues of mice were detected with biochemical indexes, including GSH-Px, T-SOD, MDA, TChE and contents of protein in brain tissues.

RESULTMice were administered with acteoside for 10 d in advance to alleviate the acquired learning disability induced by scopolamine. Compared with the model group, acteoside increased the latency period in the step-down test and reduced error times. Besides, acteoside increased the activity of GSH-Px, T-SOD, TChE and protein content in their brain tissues, but decreased MDA content.

CONCLUSIONActeoside can significantly alleviate the acquired learning disability in mice induced by scopolamine. Its mechanism may be related with its effect of inhibiting the generation of free radicals in mice and improving the function of the central cholinergic system.
