Objective To investigate the effects of mirror therapy supplemented with motor imaging training on the upper extremity functions of hemiplegic stroke patients and on their ability in the activities of daily living (ADL).Methods Forty-four stroke patients were divided into a control group and an experimental group with 22 patients in each.All were given routine rehabilitation treatment.In addition,the experimental group was given 30 minutes of mirror therapy daily supplemented with 15 minutes of motor imaging training.The control group was given routine occupational therapy.All the patients were assessed with Brunnstrom staging,the functional test for the hemiplegic upper extremity-Hong Kong (FTHUE-HK) and the Barthel index (BI) scale before therapy and after 6 weeks.Results After 6 weeks of treatment,both groups showed significant improvements in upper limb function,hand function,and ADL ability.There were significant intra-group differences and significant differences between the experimental and control groups in terms of Brunnstrom staging,FTHUE-HK scores and BI scores.Conclusions Mirror therapy supplemented with motor imaging training can benefit patients suffering hemiplegia in improving their upper limb functioning and their ADL ability.

Objective To evaluate the clinical effectiveness of 5-aminolaevulinic acid (ALA)-based photodynamic therapy (PDT) for the treatment of moderate to severe acne vulgaris.Methods From January to June 2013,a total of 43 patients with moderate to severe acne vulgaris were treated by 5 aminolaevulinic acid based PDT with red light.All patients were received three times of treatment at 2-week intervals.Clinical assessment was conducted before and at 2,4,6 and 8 weeks after treatment.Results The lesion counts of both inflammatory and non-inflammatory lesions were reduced significantly after treatment.The mean percentage reduction in inflammatory lesions was 88.9 ％ at 8 weeks after the treatment,meanwhile that in non-inflammatory lesions was 73.4％.After 8 weeks of treatment,55.8％ patients (24/43)showed clinical cure,and 41.9％ patients (18/43)showed excellent response and 2.3％ patient (1/43) showed good response.Only 4.7％ patients (2/43)showed signs of recurrence after 4 months after ALA-PDT.After one course of ALA-PDT,the symptoms in this recurrent case were significant improvement.The common adverse effects included pain,edema and transient hyperpigmentation.They could gradually disappear without a need of special intervention.Conclusions ALA-PDT is a safe and effective therapeutic option for the treatment of moderate to severe acne vulgaris.

Objective To explore the relationship between music preferences and mental health in medical students and to propose countermeasures.Methods Music Preferences Questionnaire and Chinese college students mental health scale(CCSMHS) were used to test 538 randomly selected medical students and the data was analyzed by descriptive statistics,T test and variance analysis with SPSS 20.0 and the inspection level was α=0.05.Results ①Statistically significant (P＜0.05) differences were found on somatization,anxiety,depression,inferiority,paranoid,force,social withdrawal,reliance,impulse and psychotic tendencies in medical students with different preference of music style; ②Statistically significant (P＜0.05) differences were found on anxiety and inferiority in medical students with different preference of music type; ③Statistically significant (P＜0.05) differences were found on anxiety,depression,paranoid,force,social withdrawal and reliance in medical students with different participating ways of music; ④Statistically significant (P＜0.05) differences were found on somatization,anxiety,inferiority and paranoid in medical students with different attitude about participating music activities; ⑤Medical students with different preferences of music activities preferences did not have significant difference on factor of mental health(P＞0.05).Conclusion The relationship between medical students' mental health and music preferences is very close.By training and guiding music preferences of medical students in mental health education,we can improve their mental health effectively.

Objective To study the human brucellosis infection status and its epidemic feature during 2003-2006.Methods A total of 485 blood samples of serum underwent rose bengal plate test(RBPT)and serum agglutination test(SAT),which include 422 cases having a history of contacting with sheep/goats or cattle,22 suspected eases,and 41 cases having contacted with infected persons.All cases were diagnosed according serology test and epidemiologic survey.Results The positive rates of Serum antibodies(SAT titer)were 8.8%(12/137),12.7%(8/63),13.1%(22/171)and 16.2%(19/114),respectively,during 2003 to 2006 in Tangshan,in an increasing Rend and peaked in the second and the third seasons 77.0%(47/61).The mostly infected population were those who contacted with sheep/goats or cattle,accounting for 98.4%(60/61).Livestock farmers 86.9%(53/61),and veterinarians 8.2%(5/61)were mostly likely to be infected.Assay of serum antibodies is negative in the persons contacting with infected cases.Conclusions The prevalence of human brucellsis had presented a rising tendency in highly dangerous crowd of Tangshan.Contacting with infected livestock(such as sheep/goats or cattle),especially their aborted materials and placenta were mainly transmitted modes of human brucellsis.However,cases of person-to-person transmission has not been discovered in this study.

Objective To investigate the effect of iodine excess on thyroid follicle epithelial ultrstructure and the relationship between thyroid iniury and autoimmune thyroiditis. Methods NOD.H-2h4 mice and Kunming mice were randomly divided into four groups receiving plain water,5 fold,10 fold,and 100 fold excessive iodine water.4,8 and 24 weeks after receiving iodine water,the mice were killed.After fixation with osmic acid and dual staining with uranyl chloride and citrate lead,thyroid gland ultrstructure was examined with electron microscopy.Resuits Iodine treated NOD.H-2h4 mice exhibited marked accumulation of peroxisome and secondary lysosomes,apoptosis and necrosis of thyroid epithelial cell.damage of thyroid follicles and lymphocvtic infiltration.The observed changes induced by iodine were in a dose dependent way.Conclusion The oxidative iniury on the thyroid epithelial cells induced by iodine excess might be the prerequisite for the creation of autoimmune thyroiditis.

OBJECTIVETo investigate the impact of 1, 25-(OH)2D3 on left ventricular hypertrophy (LVH) in type 2 diabetic rats.

METHODSType 2 diabetic mellitus (DM) model rats were established by intraperitoneally injecting with 30 mg/kg streptozotocin. After 8 weeks, 19 male rats were identified as diabetic with left ventricular hypertrophy (LVH) by ultrasound examination, and randomly assigned into three groups: untreated (DM-LVH, n=7), treated with insulin (DM-LVH+INS, n=6), and treated with 1, 25-(OH)2D3 (DM-LVH+VD, n=6). Healthy male rats were used as the controls group (n=6). The fasting blood glucose and the insulin level were determined weekly. The left ventricular mass index, myocardial collagen content, collagen volume fraction, and 1, 25-(OH)2D3-receptor level were determined by 4 weeks later.

RESULTSIn the DM-LVH model group, the insulin level was significantly decreased compared with the non-diabetic control group (P<0.05), whereas the blood glucose, left ventricular mass index, myocardial collagen content, collagen volume fraction, and 1, 25-(OH)2D3-receptor expression were significantly increased (all P<0.05). In the DM-LVH+INS and DM-LVH+VD groups, the insulin levels were significantly increased compared with the DM-LVH model group (P<0.05), whereas the other parameters were significantly decreased (all P<0.05).

CONCLUSION1, 25-(OH)2D3 could reverse LVH in diabetic rats and that the mechanism may involve stimulating insulin secretion and reducing blood glucose via direct up-regulation of 1, 25-(OH)2D3-receptor expression.
