Fifty-two adult male rabbits, weighing 2～3kg, were divided into three groups. 1. Peptic ulcer were induced in 25 animals by injecting 0.3ml/kg of 40％ acetic acid into the submucosa of the stomach after laparotomy under aseptic conditions 2. 19 animals were operated as above but the same amount of normal saline were injcted instead of acetic acid 3. 8 normal rabbits were raised under the same conditions without any treatment and served as controls. The thyroid glands of three groups were taken at definite time intervals (1～40 days) after the operation. The right thyroids were prepared for cryostat sections after hexane quenching (-60℃) and subjected to enzyme histochemical studies. The left thyroids were fixed in Carnoy's fluid and subjected to histological and other histochemical studies. The following results were observed.The reactions of enzymes of follicular cells were weaker than the normal in the animals of the second group during the period of 3～21 days after the operation and injection of saline. The follicular ceils became flattened and follicular lumens increased in size. These changes began to show signs of recovery on the 28th day of the experiment. In the follicular cells of the first group of animals in which peptic ulcer developed after injection of acetic acid, the similar changes were observed as in the second groug of animals during the early period of 1～3 days after operation, but from 7 to 21 days after the operation, the reactions of Acid phosphatase, Succinate dehydrogenase, Glucose-6-phosphate dehydrogenase, Glycerphosphate dehydrogenase, Peroxidase, Adensine triphosphatase and Alkaline phosphatase were stronger and the sizes of follicular lumens were smaller, the colloid droplets were more numerous than those of the animals of the second group. These changes in the follicular cells of animals of the first group began to show signs of recovering toward norrnal on the 28 th day and became almost normal on the 40 th day after operation.These findings suggest that the thyroid follicular ceils were involved in the regulatory activities of the organism for the healing of the peptic ulcer.

The histological and histochemical changes in the C cells of the rabbit thyroid during experimental peptic ulcer were studied. Acetylcholinesterase was used as the marker enzyme to identify C cells. Forty-nine adult male rabbits were randomly divided into three groups: 1. In the experimental peptic ulcer group, 24 animals were induced to develop peptic ulcer by injecting 0.15 ml/kg of 40% acetic acid into the submucosa of the stomach after laparotomy under aseptic conditions. 2. In the saline control group, 18 animals were injected with 0.15ml/kg of normal saline into the submucosa of the stomach after laparotomy. 3. In the normal control group, 7 rabbits were raised under the same conditions as groups 1 and 2 without any treatment. Thyroid glands were removed at different time intervals (1-28 days) after the operation. The right thyroids were prepared for cryostat sections and subjected to enzyme histochemical studies. The left thyroids were fixed in Carnoy's fluid and subjected to histological and other histochemical studies. The findings were as follows.In the C cells from the normal control group, the reactions of acetylcholinesterase, nonspecific esterase and acid phosphatase were rather strong. Acetylcholinesterase can be taken as a specific marker enzyme for C cells. The reactions of thiamine pyrophosphatase, succinate dehydrogenase, lactate dehydrogenase, glucose-6-phosphate dehydrogenase and ribonucleic acid were weak which suggested that normal C cells were a at a lower state of functional activity. In the saline control group, the histochemical changes showed that the C ceils were in an active functional state during the early period of the experiment, which may possibly reflect the response of C cells to the operation stress and wound healing. In the experimental peptic ulcer group, the reactions of acetycholinesterase, nonspecific esterase, acid phosphatase, succinate dehydrogenase, glucose-6-phosphate dehydrogenase, thiamine pyrophosphatase and ribonuclic acid of the C cells in the experimental peptic ulcer group were stronger than those of the saline control group 7-28 days after the operation. These histochemical changes of C cells duting this period may suggest that the C cells were active in function and perhaps participated in the regulatory activities of the organism during its recovery from the disease. In none of the three groups did the C cells show any conspicuous histological and morphological changes at any time in the experiment.

Eighty adult male Wistar rats were randomly divided into three groups: 1. In the experimental peptic ulcer group, 35 animals were induced to develop peptic ulcer by injecting 0.05 ml/kg of glacial acetic acid (more than 99%) into the submucosa of the stomach after laparotomy under aseptic conditions. 2.In the saline control group, 35 animals were injected with 0.05 ml/kg of saline into the submucosa of the stomach after laparotomy. 3.In the normal control group, 10 normal animals without any treatment were raised under the same condition as group 1 and group 2. The thyroid glands of three groups were taken at definite time intervals (1-28 days) after the operation. The right thyroids were prepared for cryostat sections after hexane quenching (-60℃) and subjected to the histochemical studies of acid phosphatase (AcP), alkaline phosphatase(AIP), a-glycerophosphate dehydrogenase (a-GPD), succinate dehydrogenase (SDH), glucose-6-phosphate dehydrogenase (G6PD), and nonspecific esterase (NsE). The left thyroids were fixed in Carnoy's fluid, stained with HE and subjected to histological study. The reactions of enzymes of the follicular cells in the group 2 were weaker than those in the group 3 (normal control) during the period of 2-21 days after the operation. The follicular cells became flattened and follicular lumens increased in size. These changes recovered to normal on the 28th day after the operation. In the follicular cells of group 1. In which peptic ulcer developed after injection of glacial acetic acid, the reaction of A1P was weaker than those in the group 3, but stronger than those in the group 2. The reations of a-GPD, SDH, and G6PD were stronger than those in the group 2, and as well as those in group 3. The reaction of AcP was stronger than those in the group 2 and group 3 during the 6-21 days after the operation. The follicular cells in the group 1 became flattened and the follicular lumens increased in size only during the period of 4-10 days after the operation and recovered on the 14th day after the operation. These findings suggested that the thyroid follicular cells of rat involved in the metabolic activities of the repair of gastric ulcer.

Using a quantitative method, the healing of the experimental gastric ulcer in rats was studied in various states of thyroid function. Rats were made hypothyroid by ingestion of thiouracil (0.1％ solution in drinking water for 10 days). Rats were made slightly hyperthyroid by ingestion of thiouracil and simultaneous administration of T_4 (3?g/100 g/day,ip) for 10 days. Rats were made hyperthyroid by administration of excess T_4 (10?g/100 g/day, ip) for 10 days. The normal rats served as controls. In all of these rats, gastric ulcer was induced by injecting a small quantity of glacial acetic acid into the submucosa of the stomach after laparotomy under aseptic conditions. After operation the rats in four groups were given those drugs as above respectively for 10 days. The volume (7.71?0.52mm~3' 5.5?0.78 mm~3 for control) and area (8.29?0.90mm~2; 4.39?0.73mm~2 for control) of gastric ulcer increased in the rats with hypothyroidism. The healing rate of gastric ulcer retarded (-30?9.4％ for volume healing rate, -50?2.1％ for area healing rate). The volume (4.75?0.88mm~3) and area (4.05?0.93mm~2) of gastric ulcer decreased in the rats with slight hyperthyroidism, and the healing rate of gastric ulcer accelerated (37?3.8％ for volume healing rate, 49?3.2％ for area healing rate). The volume (4.88?0.90mm~3) and area (6.16?0.74mm~2) and the healing rates of gastric ulcer in the rats with hyperthyroidism were similar as those of control. These findings suggested that (1) thyroxine is necessary for healing of the experimental gastric ulcer in rats and (2) thyroxine seem to accelerate healing of the experimental gastric ulcer in rats.

Objective To translate the English version of Comprehensive Frailty Assessment Instrument (CFAI) into Chinese and evalu-ate its reliability and validity. Methods CFAI was translated into Chinese with the Brislin's translation mode. From May to July, 2015, 200 community aged people in Shijiazhuang, China were assessed with the Chinese version of CFAI and World Health Organization Quality of Life-BREF (WHOQOL-BREF), and 30 of them were assessed with CFAI again after a week. The content validity was rated by six experts of gereology. The total scores of CFAI and WHOQOL-BREF were analyzed with Pearson's correlation, as well as the scores of CFAI test and retest. The CFAI were analyzed with Factor Analysis. The Cronbach's α was tested. Results There were 23 items in 4 dimensions. The content validity index was 0.782. Six factors were extracted by Factor Analysis and the cumulated variance was 64.05%. The total score of CFAI correlated with the score of WHOQOL-BREF (r=-0.764, P<0.001). The Cronbach's α was 0.704~0.897 in dimensions (P<0.001), and the r= 0.604~0.941 (P<0.001) between test and retest. Conclusion The Chinese version of CFAI is reliable and valid, that can be applied to evaluate frailty in community aged people.

Objective To investigate the effects of Edaravone (Ed) on p38mitogen-activated protein kinases/Caspase-3 (p38MAPK/Caspase-3) pathway following the diffuse injury of brain (DIB) in rats, as well as the protective effects of Edaravone on traumatic injury of brain (TIB). Method The TIB models were established by using Marmarou's method in adult male Spraque-Dawlley rats. A total of 250 rats were divided (random number)9nto control group, model group, low-dose Edaravone treatment group and high-dose Edaravone treatment group.The rats were sacrificed separately 1, 6, 24, 48 and 72 hours after DIB and the brain tissues of rats were taken.The morphological changes of neuron in hippocampus region were observed by using Nissl staining. The levels of phosphorylated p38MAPK and Caspase-3 were detected by using immunohistochemistry and Western blot. The learning and memory functions were determined with Morris water maze test from the 3rd to 7th day after injury.Results Compared with control group, some neurons displayed histopathological changes of necrosis and apoptosis in rats of model group. The levels of phosphorylated p38MAPK significantly increased in 1, 6, 24, and 48 hours after injury in rats of model group ( P ＜ 0.05), but there was no statistic significance in increase 72 hours later ( P＞ 0.05). The levels of Caspase-3 significantly increased in 6, 24, 48 and 72 hours after injury in rats of model group ( P ＜ 0.05), but there was no significant difference in increase in one hour after injury (0.59±0.29 vs.0.40±0.17, P ＞0.05).In the Morris water maze test from the 3rd to 6th day, the latency to find the platform significantly prolonged in rats of model group ( P ＜ 0.05), and the numbers of passing the platform by rats decreased on the 7th day (2.28 ± 1.18 vs. 8.20 ± 1.52, P ＜ 0.05). Compared with model group, the levels of phosphorylated p38MAPK in 6, 24 and 48 hours after injury in low-dose Edaravone group were lower (P ＜0.05), but there was no statistical difference in one hour after injury ( P ＞ 0.05). The levels of Caspase-3 in 6,24, 48 and 72 hours after injury in rats of low-dose Edaravone group were lower than those of model group ( P ＜0.05). The latency to find the platform significantly shortened ( P ＜ 0.05) and the numbers of passing the platform by rats increased (4.17 ± 1.15 vs. 2.28 ± 1.18, P ＜ 0.05) in low-dose Edaravone group. The above variables changed more prominently in high-dose Edaravone group. Conclusions Edaravone attenuates p38MAPK pathway activation, lowers the level of Caspase-3 following DIB and protects the rats against the traumatic injury of brain.

Objective To study the utility of sleep intervention combined with memory training for alleviating dysmnesia in the elderly and provide a basis for improving memory function. Methods A total of 647 community-dwelling elderly people were evaluated using the Pittsburgh Sleep Quality Index (PSQI) and the Rivermead behavioral memory test ( RBMT). One hundred and fifty elderly persons with sleep disorders and dysmnesia were divided into three groups; the control group, the memory intervention group, and the sleep plus memory training group. Sleep quality and dysmnesia were evaluated again after 3 months of intervention. Results Among the 647 elderly people, the incidence of sleep disorders was 38. 8% , and of dysmnesia was 78. 4%. Dysmnesia was significantly more prevalent among subjects who also had sleep disorders. After three months of intervention, instant recall scores had declined in the control group while scores on 7 kinds of memory function had improved significantly in the memory intervention group. Scores on 10 measures of memory and sleep quality improved in the sleep plus memory intervention group. Compared to the control group, scores on 9 kinds of memory improved significantly in the memory intervention group and scores on 11 kinds of memory improved in the sleep plus memory intervention group. Compared to the memory intervention group, scores on 5 kinds of memory had improved significantly in the sleep plus memory intervention group. Conclusions The occurrence of dysmnesia in elderly people is influenced by sleep quality. Memory training can improve their memory function, but sleep intervention combined with memory training is even more effective.

Objective To observe the intervention effect of BrainHQ visual training on depressive symptom in patients with post stroke depression.Methods Eighty patients with post stroke depression were divided into control group(n=40)and intervention group(n=40).The control group accepted routine drug therapy and conventional rehabilitation, while intervention group received BrainHQ visual training additionally.They were assessed with Hamilton depression scale(HAMD) before and 4 weeks after intervention.Results Before intervention the HAMD score between control group and intervention group(respectively(19.80±3.96), (18.43±2.94)) had no statistical difference (P＞0.05).After 4-week intervention, the HAMD score of intervention group(9.58±5.42) was significantly lower than that of control group (13.85±5.73)(P＜0.01).Before the intervention, depression level of two groups had no difference(P＞0.05).After 4-week intervention,the difference of depression level was statistically significant in two groups(P＜0.05).Conclusion BrainHQ visual training can improve depressive symptom in patients with post stroke depression.

Objective To study the effects of 3-n-butylphthalide (NBP) on motor function and learning and memory ability in rats with diffuse brain injury (DBI). Methods 128 male Sprague-Dawley rats were randomly divided into sham operation group, traumatic group,low-dose NBP treatment group and high-dose NBP treatment group with 32 rats in each group. Every group was divided into 24 h, 48 h and 72 h subgroups. DBI rat model was established according to the description of Marmarou's diffused brain injury. The histopathologic changes of cerebral tissue (0.2 cm bilateralis coronal line) were observed by light and electron microscope at 24 h, 48 h and 72 h after injury. Morris water maze and rolling test were performed daily at 24, 48 and 72 h (time points). Results Compared with the model group, the damage of brain tissue decreased, and the survival nerve cells increased (P<0.01). The behavioral tests showed that the latency to find the platform shortened (P<0.01) and the frequency of crossing the platform increased in the 72 h subgroup (P<0.01). The general movement ability enhanced in NBP groups (P<0.05). All the indexes were more significant in high-dose NBP treatment group. Conclusion NBP can improve neurological function and learning and memory function after brain injury and the molecular mechanisms is related to the decrease of the nerve cells lose and traumatic cerebral ultrastructure damage.
