Objective To investigate the clinical efficacy of Loewenstein Occupational Therapy Cognitive Assessment (LOTCA) battery for patients at the early stage of traumatic brain injury (TBI). Methods 72 patients with TBI hospitalized from January, 2013 to October, 2014 and 30 healthy controls matched gender, age and educational background were assessed with the Chinese version of LOTCA battery and Mini-Mental State Examination (MMSE) respectively. Results The score of MMSE and LOTCA were correlated (r=0.56, P<0.01). Compared with the controls, the scores of all the subtests of LOTCA decreased (P<0.01) in the patients, especially the orientation, visuomo-tor organization and thinking operation;with the more incidence of medium and serious dysfunction of all the subtests of LOTCA except perception (P<0.01), in which thinking operation was the most and attention was the least. The area under the receiver operating curve (ROC) was (0.84±0.04) in LOTCA, less than that of (0.91±0.03) in MMSE (P<0.05). Conclusion Cognition is widely impaired in patients after TBI, most involved thinking operation. LOTCA is less effective to identify cognitive dysfunction than MMSE, and can be used as an al-ternation or a supplement.

Objective To compare the validity of Montreal cognitive assessment (MoCA) versus mini-mental state examination (MMSE) in screening cognition impairment in elderly patients with cranio-cerebral trauma.Methods Cognitive function in 40 elderly patients with cranio-cerebral trauma and 40 healthy elderly individuals were assessed by MoCA and MMSE.Receiver operating characteristic (ROC) curve analysis were performed to determine the optimal sensitivity and specificity of MoCA and MMSE.Results The total score and all the sub-test scores of MoCA were much lower in cranio-cerebral trauma patients than in the control group (all P＜0.05).The total score and orientation,calculation,recall,language sub scores of MMSE were significantly decreased in the elderly patients with cranio-cerebral trauma as compared with those in the controls (P＜0.05),while there were no significant differences in the immediate memory and language scores between the two groups (both P＞0.05).The area under the receiver operating characteristic curve showed that MoCA (0.92±0.03) ＞ MMSE (0.74±0.06) (Z=2.460,P＜0.01).When screening the cognition impairment in elderly patients with cranio cerebral trauma,the best cut-off scores of MoCA and MMSE were 24.5 and 27.5 respectively.Conclusions Cognition impairment is decreased in elderly patients with cranio cerebral trauma.The MoCA is superior to the MMSE as a screening instrument in detecting cognition impairment in elderly patients with cranio-cerebral trauma.

Objective To observe the effect of cognitive rehabilitation training based on games on cognition of the traumatic brain injury (TBI) patients.Methods 60 cases of patients according with the inclusion and exclusion criteria were divided into the control group and the training group with 30 cases in each group.The Montreal cognitive assessment (MoCA) test scores of all patients were lower than 26 points.The training group accepted the cognitive rehabilitation training based on games such as exactly the same game,drum game and picture memory game,while the control group did not accept the training.After one month,all patients accepted the MoCA test again.Then we analyzed the differences of the cognition between the two groups.Results After 30 days of training,all items of the cognitive function increased except the sub-item of abstraction.While in the control group,only the scores of attention,delayed recall,orientation and the total score showed alleviation.And all the scores of the training group were higher than those of the control group except the sub-item of abstraction.Conclusions Cognitive rehabilitation training based on games can effectively improve the cognitive function of TBI patients.

BACKGROUND:Ultrasonic therapy is one of several physical therapy modalities suggested for the management of pain and loss of function due to osteoarthritis. However, its effectiveness stil remains controversial in the previous studies.
OBJECTIVE:To analyze the effect of ultrasonic therapy for the treatment of relieving knee osteoarthritis pain.
METHODS:A retrieval of Pubmed, Ovid/Medline, Ovid/EMBASE, and Cochranee database was performed. The relevant literatures were manual y retrieved. The retrieval deadline was set on March 31, 2014. Randomized control ed trials on ultrasonic therapy of knee osteoarthritis were col ected.
RESULTS AND CONCLUSION:A total of eight studies of meta-analysis were accumulated. Among them, six studies adopted visual analog scale and Western Ontario and McMaster Universities Arthritis Index, one study adopted visual analog scale only, and one study adopted Western Ontario and McMaster Universities Arthritis Index. Then the Western Ontario and McMaster Universities Arthritis Index scores were transformed into visual analog scale scores for data analysis. There was a statistical difference between the groups in the visual analog scale pain score (standardized standard deviation:-0.51;95%confidence interval:-0.68,-0.33;P=0.05). Ultrasonic therapy is an effective method for knee osteoarthritis pain.

Objective To observe the changes of cardiac function and carotid artery structure in elderly hypertensive patients with different left ventricular geometric patterns. Methods Seventy-eight elderly patients with essential hypertension were divided into 4 groups according to left ventricular geometric patterns by ultrasonography: normal ventricular geometry group(n=34),concentric remodeling group(n=18),concentric hypertrophy group(n=11)and eccentric hypertrophy group(n=15).The 24-h ambulatory blood pressure,left ventricular function,carotid artery intima-media thickness(IMT),hemodynamic parameters and incidence of plaque were measured and compared among groups.Results Patients in concentric hypertrophy group had higher 24-h average systolic blood pressure in comparison with those in normal ventricular geometry group and concentric remodeling group(P

AIM: To observe the clinical efficacy and safety of vincamine sustained release capsules on non- arteritic anterior ischemic optic neuropathy ( NAION) . · METHODS: Patients who were diagnosed with monocular onset NAION in acute stage from January to September 2015 were divided into two groups. Routine treatment such as steroid pulse therapy and neurotrophic treatment were given to all the patients. Vincamine was added to the treatment group patients with 30mg twice a day for 3mo. The best corrected visual acuity ( BCVA), mean deviation ( MD) of visual field, retinal nerve fiber layer ( RNFL ) , ganglion cell complex ( GCC ) , pattern visual evoked potential ( PVEP ) and OCT results were analyzed before and after the treatment. ·RESULTS:Totally 42 eyes of 42 patients were enrolled in our study. There were 27 patients in the treatment group, aged from 33 to 79 years old, the average value was 55. 55± 11. 83 years old. The control group has 15 patients, aged from 40 to 70 years old, the average value was 55. 71 ± 10. 06 years old. There were no statistical differences between the two groups in the baseline. After 3mo of the treatment, MD value of the two groups were lower compared with the baseline, the difference was statistically significant in the treatment and control group respectively (t= 2. 342, 2. 692; P = 0. 027, 0. 041). The difference of PVEP amplitude and potential of the two groups before and after the treatment were not statistically significant. The thickness of retinal nerve fiber layer and the ganglion cell complex were all lower than the baseline, and the difference was statistically significant (P<0. 001). The treatment of the two groups were both effective, the treatment group has better treatment effect than the control group. Adverse events related to the treatment of vincamine had not been found. ·CONCLUSION:Vincamine is helpful in the treatment of non-arteritic anterior ischemic optic neuropathy.

Objective To prepare recombinant adenovirus pAd-gal-9 containing murine galectin-9 and explore galectin-9's pro-apoptotic effect on T lymphocytes. Methods The recombinant adenovirus plas-mid pAd/CMV/V5-DEST-gal-9 was prepared by conventional molecular cloning and LR reaction. The pAd/ CMV/V5-DEST-gal-9 linearlized by Pac I was transfected into 293A cells with Lipofectin 2000. Eight days after transfection, the 293A cells were subjected to freeze/thraw circle for three times and the supernatant was collected after centrifugation. Higer titer pAd-gal-9 was produced by large-scale infection of 293A cells with the supernatant containing pAd-gal-9. The supernatant was condensed to get purified pAd-gal-9 by CsCl density gradient centrifugation. After titer determination with gradient dilution of harvested pAd-gal-9 infec-tion in 293A-seeded 96-wells, pAd-gal-9 was used to infect the CHO cell line. Immunohistological assay, Western blot and flow cytometry were employed to ascertain the subcellular location expression of galectin-9. We added solid-phase transgenic CHO cells or freshly-cultured supernatant to medium containing activated T cells to detect the pro-apoptotic effect of galectin-9. Results The pAd-gal-9 was prepared successful. Im-munohistochemical staining of CHO infected with pAd-gal-9 confirmed that galectin-9 was expressed in the cytosol. Intercellular staining indicated that mean fluorescence intensity of galectin-9 was significantly higher in pAd-gal-9-infected CHO group than control group. Supernatant from pAd-gal-9-infected CHO promoted the apoptosis of T cells. The percent of apoptotic T cells was higher than the Tim-3 positive T cells. Conclu-sion CHO infected with pAd-gal-9 can secret galectin-9 to promote the apoptosis of activated T cells via Tim-3-independent mechanisms.
