Objective To quantitatively assess the left ventricular systolic dyssynchrony in patients with varied degrees of chronic congestive heart failure after old myocardial infarction(OMI) by real-time three-dimensional echocardiography(RT-3DE) and investigate the clinical value of the systolic dyssynchrony index(SDI). Methods Forty patients with congestive heart failure after OMI (infarction group) were divided into the severe dysfunction group (LVEF ≤35 %) and the mild dysfunction group (35 % ＜ LVEF＜50%) ,and 30 normal subjects served as the control. RT-3DE was performed on all subjects to obtain the 17-segmental time-volumetric curves and global systolic function. SDI changes in above groups and the correlation between SDI and LVEF were analyzed. Results The SDI of the infarction group was significantly higher than that of the normal control group ( P ＜0. 01 ). The SDI of the severe dysfunction group was significantly higher than that of the mild group (P＜0.01). SDI and LVEF were negatively correlated ( r = -0.84, P ＜0. 01 ). The dyssynchrony rate in the infarction group was 85 %,in the severe dysfunction group was 100%, in the mild group was 75%. Conclusions Left ventricular systolic dyssynchrony is prevalent in patients with OMI, and it is negatively correlated with the LVEF. SDI is a sensitive indicator in assessing left ventricular systolic dyssynchrony. RT-3DE has a unique advantage in the evaluation of the left ventricular systolic dyssynchrony,especially in the patients with myocardial infarction.

Objective To explore the effects of the mindfulness mode intervention on the adverse reaction of the patients with breast cancer during the period of chemotherapy.Methods 75 patients with breast cancer during the period of chemotherapy were randomly assigned to the control group(38 cases) and the intervention group(37 cases).All patients received the routing nursing of chemotherapy.In addition the intervention group received the mindfulness intervention.The adverse reaction of chemotherapy questionnaire was used to investigate the level of their adverse reaction before the intervention and two months after the intervention.Results After the intervention,the scores of the adverse reaction in the intervention group was (32.19± 7.70)points,less than that of the control group,which was (36.97±10.03)points.There was statistically significant difference between two groups.Conclusions The mindfulness model intervention could reduce the adverse reaction of the patients with breast cancer.

Because of its specificity , significant effect , low side effect , molecular targeted therapy has been applied in the treatment of breast cancer .Recently, various molecular targeted drugs have been exploited including targeted HER family, VEGF, multi-targeted therapeutic drugs , and drugs combination .

ObjectiveTo investigate the event-based prospective memory (EBPM)and time-based prospective memory( TBPM )in stable patients with schizophrenia and to explore the relationships between prospective memory and social functioning.Methods40 schizophrenic patients and 40 normal controls matched in age,gender and education were assessed with a neuropsychological battery of tests including EBPM and TBPM tasks.The patients were also assessed with social disability screening schedule(SDSS).ResultsA statistically significant in EBPM was observed between patients with schizophrenia and normal controls (4.18 ± 1.04 vs 5.33 ±0.86,t=- 5.408,P ＜ 0.01) and the same result in TBPM ( 3.45 ± 1.48 vs 5.20 ± 0.82,t =- 6.522,P ＜ 0.01).In patients with schizophrenia TBPM was impaired more significantly than EBPM ( z=-3.238,P＜0.01 ).After controlling the total score of PANSS,the negatively correlate was showed between the total scores of SDSS and EBPM ( r =- 0.346,P ＜ 0.05 ),TBPM ( r =- 0.374,P ＜ 0.05 ) in the patients.ConclusionThe results suggest schizophrenic patients impairs both EBPM and TBPM,and TBPM is impaired more significantly than EBPM.PM shows positively correlated with social functioning moderately in the patient.

Objective To investigate the relationship of cellular immunity of the hand-foot-mouth disease (HFMD) children and the disease severity and the variation following the recovery of disease.Methods A total of 560 HFMD cases was collected,and divided into severe and common groups.Another 120 cases were collected for comparison.T cell subsets (CD3 +,CD4 +,and CD8 +) rates were tested.The difference in cell immunity in each group were compared,and the comparison of cell immunity improv-ment during acute and recovery periods was conducted at the same time.Results In the 560 cases of children with HFMD,CoxA16-positive rate in common group was higher than that in severe group (x2 =280.72,P ＜0.01,severe cases); EV71 and other virus positive rates in severe group were higher than that in common group (x2 =127.75,P ＜ 0.01,x2 =5.43,P ＜ 0.05).Cell immunity was compared among3 groups (t =9.82,4.98,3.06); CD3+,CD4+,CD8+ results,tested within 2h after admission and after 1 week,were compared between severe and common groups (common group t =7.73,3.86,4.71; severe group t =6.13,2.60,3.36).Compared to severe group,cell immunity improvement was more obvious between before and after 1-week treatment in common group (t =2.57,2.51,2.95).The difference was statistically significant (P ＜ 0.05).Conclusions According to the etiology test of children with HFMD,CoxA16-positive rate was higher in common group; EV71 and other virus positive rates were higher in severe group.Cell immunity function decreased in severe and common group at the beginning of the disease; it was,however,significantly restored after 1-week treatment; and it was related to the severity of clinical symptoms.

Objective To explore the incidence and significance of intra-and extraosseous edema accompanying benign tumors and tumor like diseases.Methods Imaging studies including MR,CT and plain radiograph were retrospectively reviewed in 245 cases of benign osseous tumors and tumor like diseases proved by pathology(borderline tumor,cases associated with pathological fractures,cases with lesions of skull were excluded from the study).The incidence of bone marrow and soft tissue edema were defined on T2WI with fat suppression on MRI in all the cases.x2 test was performed for the incidence rate of edema in the benign tumors and tumor like diseases.The pre-operative diagnoses were reviewed,and the influence of edema to the differential diagnosis between the benign and malignant was analyzed.Results The total incidence of bone marrow and soft tissue edema associated with benign tumors and tumor like diseases was 37.1％ (91/245),which included Langerhans cell histiocytosis 85.2％ (23/27),osteoblastoma85.0％ (17/20),osteoid osteoma93.6％ (29/31),ehondroblastoma 87.0％ (20/23).There was no statistically significant difference of edema incidence among the above-mentioned four diseases.(x2=6.35,P＞ 0.05).Both cases of endosteal capillary hemangioma had edema around.No edema was found around the lesions of other kinds of diseases.41 of 91 cases (45.1％) with edema were misdiagnosed as malignant tumor by MRI pre-operatively.Conclusion The marrow and soft tissue edema is a common sign in the benign bone tumor and tumor-like diseases,and it is frequently seen in Langerhans cell histiocytosis,osteoblastoma,osteoid osteoma,chondroblastoma.

ObjectiveTo explore the effects of the conjugate prepared from the cholera toxin B subunit(CB) and nerve growth factor(NGF) on the spatial learning and memory abilities and cholinergic function.MethodsThe conjugate of CB-NGF was prepared by the improved sodium metaperiodate method and nasally administrated to the β-amyloid protein(Aβ25-35) induced amnesic mice for 7 days with 2 dosage (7-5 μg/d、15 μg/d). Spatial learning and memory abilities were evaluated by Morris water maze and cholinergic function was assessed with the choline acetyl transferase (ChAT) immunohistochemical methods.ResultsMorris water maze test showed that the escape latency in Aβ25-35-treated mice prolonged and the staying time reduced in the crossed first quadrant where the platform had been located, compared with the control mice (P<0-01). In addition, the number of ChAT positive neuron declined in the model mice(P<0-001). CB-NGF nasal administration significantly shortened the escape latency and elevated the staying time and number of ChAT positive neuron(P<0-01).ConclusionCB-NGF treatment can improve the spatial and memory performance which may involve the neuroprotection to cholinergic system.

BACKGROUND:Angiotensin-converting enzyme as a key enzyme of the renin-angiotensin system, through the degradation effects of substance P mechanism, is involved in the occurrence and development of Alzheimer’s disease.
OBJECTIVE:To research the relationship between angiotensin-converting enzyme gene polymorphism and Alzheimer’s disease in Jiamusi region, as wel as the effect of gender and hypertension on the relationship.
METHODS:This case-control study included 96 Alzheimer’s disease patients. Another 102 subjects served as controls coming from the same area and in the same environmental condition. DNA segments were amplified using PCR in 20 g/L agarose gel electrophoresis and observed under ultraviolet lamp. II, ID, DD genotypes and genotype frequencies were calculated for statistical analysis. On this basis, according to clinical data col ected, we investigated association of Alzheimer’s disease with hypertension and gender.
RESULTS AND CONCLUSION:There was significant difference between Alzheimer’s disease patients and controls in angiotensin-converting enzyme genotypes and al ele frequency. There was statistical y significant difference between Alzheimer’s patients with hypertension and controls in angiotensin-converting enzyme genotypes and al ele frequency. There was no statistical difference between Alzheimer’s disease patients with different genders and controls in angiotensin-converting enzyme genotypes and al ele frequency. These findings indicate that there are some relationships between angiotensin-converting enzyme polymorphism and Alzheimer’s disease. II genotype is a risk factor for Alzheimer’s disease, angiotensin-converting enzyme II genotype is a risk factor for Alzheimer’s disease with hypertension.

ObjectiveTo investigate the event-based prospective memory (EBPM)and time-based prospective memory( TBPM )in late-onset depressive patients and to explore the relationships between prospective memory and depressive symptoms.Methods 32 late-onset depressive patients and 30 normal controls matched in age,gender and education were assessed with a neuropsychological battery of tests including EBPM and TBPM tasks.The patients were also assessed with Hamilton Depression Scale (HAMD).ResultsA statistically significant in EBPM was observed between patients with late-onset depression and normal controls (2.31 ± 1.06 vs 3.07± 0.87,t =- 3.052,P ＜ 0.01) and the same result in TBPM (2.03 ± 0.93 vs 2.67 ± 0.92,t =- 2.695,P ＜0.01 ).The negatively correlate was showed between the total scores of HAMD and EBPM ( r =- 0.436,P =0.013 ),TBPM ( r =- 0.467,P =0.007 ) in the patients.ConclusionThe results suggest late-onset depressive patients impair both EBPM and TBPM.Prospective memory shows correlation with depressive symptoms in the patients.

Objective To survey the status and related demands of advanced clinical training among community general practitioners (GPs) in Shanghai.Methods A survey on the status and demands of advanced clinical training was conducted with a self-designed questionnaire among GPs in Minhang District and Jiading District of Shanghai from January to May 2016.The questionnaire included basic information , experience of advanced clinical training , satisfaction with training and training demands .Results Total 526 questionnaire were distributed and 478 valid questionnaires were returned with a response rate of 90.9%. Among the participants 202 (42.3%) had experience of advanced clinical study ; the training units were mainly secondary hospitals in Shanghai (69.3%, 140/202); 67.2%(131/195) participants considered that the previous training did not fully meet the needs of the community .There was significant difference in the training demands among participants with different ages , professional titles, and working years ( χ2＝12.754, 7.912, 4.501, all P＜0.01); those with younger age, higher education and shorter working years had higher training demands .Survey showed that 57.3%( 274/478 ) of participants demanded further studies in the future; 58.3%( 239/410) of them chose tertiary hospitals in Shanghai as training unit , 79.0%(321/406) chose internal medicine and geriatrics as training specialties , particularly in outpatient clinic (73.2%, 298/407); the length of study should be 3 months (32.8%, 132/402) or 6 months (27.6%, 111/402), and completed in segments (61.5%, 253/411).The purpose of training was mainly to upgrade clinical competence (94.2%, 258/272); busy working schedule (53.4%, 66/116) was the main reason for not intending the advanced clinical studies .Conclusions The community general practitioners in Shanghai have high demands for advanced clinical training .The training should meet the needs of clinical practice in community and the mode of study should be more flexible .
