Objective:To explore the effect of handicraft training administered over the Internet on sensation disorders and on the mental status and life quality of stroke survivors.Methods:A total of 75 stroke survivors in the sequelae stage and with sensory disturbance were randomly divided into a general training group of 26 (group A), a handicraft training group of 26 (group B), and a handicraft training group of 23 using Internet instruction (group C). In addition to 40 minutes of routine physical and sensory training rehabilitation every morning, groups A and B were given traditional training and handicraft training, while group C was given handicraft training delivered over the Internet for 40 minutes every afternoon, five days a week for 4 weeks. The traditional training involved inserting wooden boards, plate grinding, as well as sorting beans. The handicraft training involved digital painting, making non-woven flowers, silk screening flowers and paper-rolling. Before and after the 4 weeks of treatment, all of the subjects were assessed using the Fugl-Meyer sensory assessment (FMA-S), the Hamilton Anxiety Scale (HAMA), the Modified Barthel Index (MBI), and the physical component summary scale (PCS) and mental component summary scale (MCS) of the 36-item short-form health survey.Results:After the treatment, significant improvement was observed in their average scores of all three groups in all of the assessments. Groups B and C showed significantly greater improvement in the average FMA-S, HAMA and MBI scores than group A. And the average HAMA and MCS scores of group C were significantly better than those of group B.Conclusion:Handicraft training delivered over the Internet can improve the sensory functioning, mental status and life quality of stroke survivors in the sequelae stage with sensory disturbance.

Objective:To explore the relationship between executive function and gait in cases of mild amnestic cognitive impairment (aMCI).Methods:Twenty aMCI hospital patients formed an observation group, while 20 healthy counterparts were the control group. Both groups underwent the Tinetti test, followed by the " normal walking" single-task test and the " normal walking + Go/No-go" dual-task test. The pace, step width, stride length, Go/No-go task response time and accuracy rate were recorded.Results:In the single-task test, there was no significant difference in pace or stride width between the two groups, but the average stride length of the observation group (1.11±0.04)cm was significantly shorter than that of the control group. However, in the dual-task test, the average pace time (0.96±0.08)sec and stride length (1.02±0.06)cm of the observation group were significantly smaller than the control group′s averages, while their step width (0.11±0.02)cm was significantly wider. There was no significant difference between the two groups in the response time in a single (Go/No-go) task, but in the dual-task test, the observation group′s average time was significantly longer than the control group′s and the accuracy was significantly poorer. Both the error rate and the non-response rate were significantly higher than among the control group.Conclusions:Mild amnestic cognitive impairment reduces stride length and pace when walking and impairs executive function.

OBJECTIVE To investigate the effect of dioscin on renal injury in septic rats and its possible mechanism. METHODS The septic rat model was induced by using cecal ligation and puncture. Sixty model rats were randomly divided into model group （0.5% sodium carboxymethyl cellulose solution）， dioscin low-dose， medium-dose and high-dose groups （30， 60， 120 mg/kg） and dexamethasone group （positive control， 10 mg/kg）， with 12 rats per group； another 12 rats were selected as the sham operation group （0.5% sodium carboxymethyl cellulose solution）. After 15 minutes of modeling， rats in each group were injected with medicine/0.5% sodium carboxymethyl cellulose solution via the tail vein. Twenty-four hours after administration， the levels of creatinine （Cr）， blood urea nitrogen （BUN）， neutrophil gelatinase associated lipocalin （NGAL）， kidney injury molecule-1 （KIM- 1）， interleukin 6 （IL-6）， IL-1β and tumor necrosis factor-α （TNF-α） in serum and malondialdehyde （MDA） in renal tissue， superoxide dismutase （SOD） activity and the protein expressions of nuclear factor E2-related factor 2 （Nrf2）， heme oxygenase-1 （HO-1）， NOD-like receptor protein 3 （NLRP3） were detected； renal histomorphology was observed. RESULTS Compared with model group， pathological injury of renal tissue was improved significantly in dioscin low-dose， medium-dose and high-dose groups； the levels of Cr， BUN， NGAL， KIM-1， IL-6， IL-1β and TNF-α in serum， MDA level and protein expression of NLRP3 in renal tissue were decreased significantly （P＜0.05）； SOD activity in renal tissue， protein expressions of Nrf2 and HO-1 were increased significantly （P＜0.05）， in a dose-dependent manner （P＜0.05）. The pathological damage of renal tissue in the dioscin high-dose group was similar to dexamethasone group， and there was no statistically significant difference in the levels of the above indicators （P＞0.05）. CONCLUSIONS Dioscin can activate the Nrf2/HO-1 signaling pathway to inhibit NLRP3 inflammasome， and realize the inhibition of inflammatory factors and oxidative stress， so as to protect the kidney injury in sepsis.
