Objective: To evaluate the quality of life of schizophrenic patients spouses living in the community. Methods:One hundred schizophrenic patients spouses and 60 control subjects were adminstered the General Quality of Life Inventory (GQOLI). Results: The schizophrenic patients spouses reported significantly lower score on the quality of life than the controls in the domains of physical health, mental health, social function and economic condition. The characteristics of disease played an important role in the quality of life. Conclusion: The quality of life of schizophrenic patients spouses were poorer than that of control subjects.

Three key ethical issues in neurotherapeutics research are discussed: the ethical challenges arising from changes in the financial incentive of researchers and their institutions,risk-benefit analysis on testing innovative interventions,and the research for informed consent.

Objective To examine the relationship between quetiapine serum concentration,dose,therapeu-tic efficacy and side effects in male patients with schizophrenia.Methods Sixty-three male patients with schizo-phrenia were collected.They were treated openly for 8 weeks with quetiapine,the dose was adjusted according to clini-cal improvement and tolerance.The plasma quetiapine concentrations,therapeutic efficacy and adverse drug reactions were observed after the 4 -week treatment period,and at the end of the 8 weeks of the treatment.Results After 4 weeks,the serum concentration had significant correlation with age,the disease duration and education level.After 8 weeks,there was significant correlation between serum concentration and age.We found a correlation between dose and serum concentration of quetiapine,and no relationship between serum concentration and PANSS scores.Side effects were correlated with 4 weeks′serum concentrations.Conclusion Quetiapine is effective for male patients with schizophrenia.Age,quetiapine dose and side effects have significant correlations with the serum concentration.It appears that plasma quetiapine concentration has no effects on therapeutic efficacy.

Objective To develop the bipolar depression index scale (BDIS) and test the validity and reliability of BDIS.Methods The original bipolar depression index scale (BDIS) was developed by the clinical features of bipolar depression reported by the studies focused on comparing the bipolar depression (BP) and unipolar depressive disorder (UP).46 patients with bipolar depression and 44 patients with unipolar depression were rated the original BDIS and enrolled consecutively by DSM-IV.Results There were eleven items in the BDIS.The interrater reliability between eleven items and BDIS score ranged from 0.61 to 0.87.The correlation coefficients between eleven items and BDIS score ranged from 0.53 to 0.73.The Cronbach's alpha of BDIS was 0.68.The mean BDIS score of BP(7.26 ± 3.12 ) was significantly higher than that of UP( (4.80 ± 3.08 ), (P ＜ 0.01 ).The BDIS scores were significantly correlated with the scores of Mood Disorder Questionnaire ( coefficient 0.56) and 32-item hypomania checklist ( coefficient 0.45).The BDIS score could discriminate between BP patients and UP patients by the ROG curve analysis and 5 was the best cutoff score ( sensitivity 0.80, specificity 0.64).Conclusions The validity and reliability of BDIS are fit for the requirements of psychometrics.BDIS may use to differentiate between bipolar depression and unipolar depression in the practice.

Sperm-mediated gene transfer (SMGT) is one of the most methods in the transgenic animal research and the efficiency of spermatozoa binding and internalization exogenous DNA after sperm/DNA co-culture is important to a successful SMGT.In this study,the influencing factors of exogenous DNA uptake by spermatozoa were detected using DIG labeled EGFP as exogenous gene.The results demonstrated that porcine spermatozoa could spontaneously take up exogenous DNA which mainly binding occurs on the sub-acrosomal and nuclei region of the sperm head.The rate of spermatozoa binding exogenous DNA increased with the extending action of time.At 37℃ and 39℃,the rate of spermatozoa uptake exogenous DNA would not increase after 60 min incubation,and the similar result was observed on 90 min at 17℃.Binding rates and internalization rates of washed ejaculated sperm cells from the 15 boars varied between 6.57%-35.81% and 2.990%-24.66%,respectively.The binding rate and intemalization rate were mostly inhibited by seminal plasma.The binding rates were significantly increased by liposome and DMSO,respectively.Dead-spermatozoa could bind exogenous DNA,the intermalization process could not be completed.Furthermore,the highest binding rate was found in membrane broken spermatozoa as a result of freeze-thawing and this was independent of the sperm donors.

BACKGROUND:In recent years, vacuum sealing drainage technology has been widely used in the treatment of orthopedic wounds or to facilitate skin graft survival, both of which have achieved good results.
OBJECTIVE:To observe the curative effects of vacuum sealing drainage technology in the wound healing after limb open fractures, soft tissue defects, pressure sores, and chronic osteomyelitis.
METHODS:Fifty-four patients of fractures combined with soft tissue defects, postoperative exposed bone, osteomyelitis, a large area of pressure ulcers or severe infections, selected from the 273rd Hospital of PLA, were randomly divided into test and control groups according to the wishes of patients. The test group included 36 patients who were treated with vacuum sealing drainage using polyethylene ethanol hydration seaweed salt after debridement, and the control group included 18 patients who were treated with conventional dressing. Wound cleaning time, number of dressings, and wound healing time were detected and compared in the two groups.
RESULTS AND CONCLUSION:Compared with the control group, the wound cleaning time and wound healing time were shorter in the test group, and the number of dressings was also decreased in the test group (P<0.05). After removal of sponge dressings, in the test group, wound granulation was fresh and grew obviously with no exudates after the necrotic residue was removed and vacuum sealing drainage was changed. For the bone exposure patients, the wound area was reduced, or even there was no exposed bone any more. After skin grafting, vacuum suction and pressure due to vacuum sealing drainage technology made al skin grafts survive. In the patients with chronic osteomyelitis, the exudates were gradual y reduced until disappeared after vacuum sealing drainage was exchanged three or four times, and pathogens were not found in bacterial culture. After combined treatment of debridement and vacuum sealing drainage, there were many fresh granulations in the patients with large areas of pressure sores;after replacement of vacuum sealing drainage several times, the granulation grew to the same height with the surrounding skin.

OBJECTIVE: To determine the brain function and structure in patinets with first-episode panic disorder (PD). METHODS: All subjects (24 PD patients and 24 healthy subjects) received MRI scan and emotional counting Stroop task during the functional magnetic resonance imaging. Blood oxygenation level dependent functional magnetic resonance imaging and voxel-based morphometric technology were used to detect the gray matter volume. RESULTS: Compared with the healthy controls, left thalamus, left medial frontal gyrus, left anterior cingulate gyrus, left inferior frontal gyrus, left insula (panic-related words vs. neutral words) lacked activation in PD patients, but the over-activation were found in right brain stem, right occipital lobe/lingual gyrus in PD patients. Compared with the healthy controls, the gray matter volume in the PD patients significantly decreased in the left superior temporal gyrus, right medial frontal gyrus, left medial occipital gyrus, dorsomedial nucleus of left thalamus and right anterior cingulate gyrus. There was no significantly increased gray matter volume in any brain area in PD patients. CONCLUSION PD patients have selective attentional bias in processing threatening information due to the depression and weakening of the frontal cingulated gyrus.

OBJECTIVE: To explore the functional locations of brain regions related to internet addiction (IA)with task-functional magnetic resonance imaging (fMRI). METHODS: Nineteen college students who had internet game addition and 19 controls accepted the stimuli of videos via computer. The 3.0 Tesla MRI was used to record the Results of echo plannar imaging. The block design method was used. Intragroup and intergroup analysis Results in the 2 groups were obtained. The differences between the 2 groups were analyzed. RESULTS: The internet game videos markedly activated the brain regions of the college students who had or had no internet game addiction. Compared with the control group, the IA group showed increased activation in the right superior parietal lobule, right insular lobe, right precuneus, right cingulated gyrus, and right superior temporal gyrus. CONCLUSION Internet game tasks can activate the vision, space, attention and execution center which are composed of temporal occipital gyrus and frontal parietal gyrus. Abnormal brain function and lateral activation of the right brain may exist in IA.

Objective To study the effect of olanzapine combined with repetitive transcranial magnetic stimulation(rTMS) in the treatment of phonism dominated schizophrenia.Methods From August 2015 to November 2016,112 patients with phonism based schizophrenia in Ningbo Kangning Hospital were selected in the research . According to the different treatment ,the patients were divided into observation group and control group ,with 56 cases in each group.The observation group was treated with olanzapine combined with rTMS chemotherapy ,the control group was treated with olanzapine.Before and after treatment,the positive and negative symptom scale ( PANSS) score, Wisconsin Card Sorting Test ( WCST) score of the two groups were observed.The clinical efficacy was compared between the two groups.Results Before treatment,there were no statistically significant differences in PANSS score and WCST score between the two groups ( all P＞0.05).After treatment for 1 week,2 weeks,4 weeks,the PANSS scores of the two groups were significantly lower than those before treatment (F＝170.710,106.028,28.530,30.328, 25.806,10.832,203.342,372.253,all P＜0.05).The PANSS scores decreased more significantly in the observation group.After treatment for 1,2,4 weeks,the scores of positive symptoms in the observation group were (25.95 ±3.50)points, (24.72 ±4.50)points and(16.51 ±2.70)points,respectively,which were significantly lower than those in the control group[(27.27 ±2.03)points,(27.80 ±5.37)points,(19.53 ±3.07)points](t＝2.441,3.290,5.528,all P＜0.05).After treatment for 1 week,2 weeks,4 weeks,the continuous response scores in the observation group were (45.62 ±5.41)points,(44.69 ±4.91) points,(35.89 ±3.30) points,respectively,which were significantly lower than those in the control group[(50.61 ±5.35)points,(46.80 ±5.14)points,(42.70 ±5.04)points](t＝4.908, 2.221,8.459,all P＜0.05).The scores of continuous errors in the observation group were (49.47 ±4.59) points, (46.53 ±6.05) points and (36.35 ±5.18) points,respectively,which were lower than those in the control group [(83.1 ±6.58)points,(81.85 ±6.70)points and (76.86 ±76.86)points](t＝31.369,29.279,38.464,all P＜0.05).After treatment for 1 week,2 weeks,the classification scores in the observation group were (4.21 ±2.03) points and (5.35 ±2.23) points,respectively,which were significantly higher than those in the control group [(3.35 ±1.24)points and (3.95 ±1.24)points] (t＝2.705,4.106,all P＜0.05).The effective rate was 91.0%in the observation group ,which was 89.2%in the control group,there was no statistically significant difference (χ2＝0.022,P＞0.05).Conclusion Olanzapine combined with rTMS is effective in the treatment of schizophrenia ,and olanzapine combined with rTMS is more effective in improving the cognitive ability of patients than olanzapine alone .

Objective:To investigate the effects and significance of acute and chronic trauma on brain degree centrality (DC) in patients with post-traumatic stress disorder (PTSD) who lost their only child at resting state.Methods:Retrospectively, the study enrolled a total of 51 parents with PTSD, including 35 PTSD parents whose children was lost in emergencies (acute bereaved PTSD group) and 16 PTSD parents whose children was lost of chronic causes such as diseases (chronic bereaved PTSD group). Fifty local adults were also included as healthy controls (HC group). The clinical administered PTSD scale(CAPS) was used to evaluate the severity of the subjects' clinical symptoms.Resting-state functional magnetic resonance imaging(fMRI) data of all subjects were collected and DC values were calculated.SPSS 22.0 software was used for statistical analysis.Covariance analysis was performed among three groups, while post hoc was performed between any two groups.What's more, correlation analyses were utilized between abnormal brain regions and the scores of CAPS.Results:Significant group effects were found in multiple regions, including the right inferior temporal gyrus (MNI: x, y, z=66, -27, -21), right temporal pole (MNI: x, y, z=54, 15, -9), right orbital inferior frontal gyrus (MNI: x, y, z=42, 21, -15), bilateral medial superior frontal gyri (MNI: right x, y, z=6, 63, 12; left x, y, z=-3, 60, 18), left inferior parietal angular gyrus (MNI: x, y, z=-45, -36, 51) and left postcentral gyrus (MNI: x, y, z=-45, -33, 51). Compared with HC group, the DC of two patient groups increased in the right inferior temporal gyrus (MNI: acute x, y, z=63, -27, -21; chronic x, y, z=63, -21, -27); the DC of acute bereaved PTSD group decreased in the right temporal pole (MNI: x, y, z=45, 21, -15) and the right orbital inferior frontal gyrus (MNI: x, y, z=48, 24, -12), while the DC of chronic bereaved PTSD group decreased in the left inferior parietal angular gyrus (MNI: x, y, z=-45, -36, 51) and left postcentral gyrus (MNI: x, y, z=-45, -33, 51). Compared with chronic bereaved PTSD group, the DC of acute bereaved PTSD group increased in the left inferior parietal angular gyrus (MNI: x, y, z=-33, -39, 42) and left postcentral gyrus (MNI: x, y, z=-45, -33, 51), while decreased in the right temporal pole (MNI: x, y, z=51, 12, -9), right orbital inferior frontal gyrus (MNI: x, y, z=42, 21, -15) and bilateral medial superior frontal gyri (MNI: left x, y, z=0, 57, 15; right x, y, z=3, 57, 15). In chronic bereaved PTSD group, the DC of the left postcentral gyrus was negatively correlated with C1 (avoid trauma-related thoughts, feelings) score in CAPS ( r=-0.606, P=0.028). In acute bereaved PTSD group, the DC of the left medial superior frontal gyrus was negatively correlated with D4 (high vigilance) score ( r=-0.416, P=0.020). Conclusion:There exist functional abnormalities of multiple brain regions in acute and chronic bereaved parents with PTSD.The high arousal symptoms of the former may be related with the abnormalities of prefrontal-amygdala neural circuit, while the latter show higher avoidance which may be associated with the dysfunction of somatosensory brain regions such as postcentral gyrus.
