ABSTRACT
Objective:To investigate whether rumination and family functioning can predict the level of depression after 1 year of follow-up in patients with first-episode depression, and whether family functioning plays a mediating role between rumination and depression level.Methods:Sixty-five patients with first-episode depression who met the enrollment requirements were included, and all subjects were assessed the 17-item Hamilton depression scale(HAMD-17), rumination response scale(RRS) and family assessment device(FAD). All subjects were followed up for 1 year, and the predictive effects of rumination and family functioning at baseline on the level of depression after 1 year of follow-up were investigated by hierarchical linear regression analysis and mediation analysis.Results:At the baseline stage, rumination, role, affective involvement (AI) and general functioning (GF) were significantly positively associated with depression level after 1 year of follow-up in patients with first-episode depression ( r=0.49, P<0.01; r=0.30, P=0.02; r=0.43, P<0.01; r=0.50, P<0.01; respectively). Rumination, AI and GF at the baseline stage predicted depression level after 1 year of follow-up ( β=0.315, t=2.954, P=0.005; β=0.261, t=2.550, P=0.013; β=0.323, t=2.952, P=0.005). Mediation analysis showed that AI and GF partially mediated the relationship between rumination at baseline and depression level at 1 year follow-up (point estimate value for AI=0.040, 95% CI=0.012-0.090); point estimate value for GF=0.066, 95% CI=0.017-0.143). Conclusions:Rumination and family functioning at baseline in first-episode depressed patients can predict the depression level at 1 year follow-up.Family functioning partly mediates the relationship between the baseline rumination and the depression level at 1 year follow-up.
ABSTRACT
Objective: To investigate the hemostasis effect of hemocoagulase for injection in scalp incision in craniocerebral surgery, and evaluate its effect on coagulation function and drug safety. Methods: Before undergoing craniotomy, 60 patients were randomly divid-ed into the study group and the control group. The study group was injected with hemocoagulase for injection at 1u im at the night before surgery, 1u im 1h before incision and 1u im 15min before incision. The control group was injected with 0. 9% saline at the same time with the same volume. The hemorrhagic volume, hemorrhagic volume per square decimeter, hemostatic time, blood coagulation and ad-verse events were tested and compared between the groups. Results: In the study group, the mean hemorrhagic volume was (37. 18 ± 2. 96)g, the mean hemorrhagic volume per square decimeter was (0. 23 ± 0. 16)g·cm-2and the mean hemostatic time was (125. 53 ± 36. 42)s. In the control group, the corresponding value was (60. 69 ± 2. 30) g, (0. 42 ± 0. 25) g·cm-2and (182. 72 ± 52. 29) s, re-spectively. The hemorrhagic volume, hemorrhagic volume per square decimeter and hemostatic time significantly decreased in the study group when compared with those in the control group (P<0. 05). No significant difference in blood coagulation and safety (P>0. 05). No adverse event was reported. Conclusion: Hemocoagulase for injection shows promising hemostasis effect with high safety, which can ensure craniocerebral surgery going well with shortened operation time.
ABSTRACT
Objective To explore the belief about medicines in patients with treatment-resistant de-pression ( TRD) and its influencing factors. Methods 106 patients with TRD were recruited to complete the survey of demographic characteristics,Hamilton Depression Scale-17 ( HAMD-17) and belief about Med-icine Questionnaire-Specific ( BMQ-S) . Results ①The score of BMQ-s was higher in TRD patients with medical insurance than that of patients with self-funded(rural social insurance(1.11±0.96),medical insur-ance(0.84±1.33),self expense(0.13±1.72),F=2.81,P<0.01).The score of BMQ-s was higher in TRD pa-tients with serious depression than that of patients with mild to moderate depression((1.07±1.19),(0.34± 1.41),t=2.77,P<0.01).The score of BMQ-s was higher in TRD patients with fewer episodes of depression than that of patients with more episodes of depression (0 time(1.10±0.99),once and twice(0.95±1.31),3 times and above(0.31±1.56),F=3.42,P<0.05).The score of BMQ-s was higher in TRD patients without stigma than those with stigma((1.03±1.21),(0.34±1.43),t=2.58,P<0.01).The score of BMQ-s was high-er in TRD patients with more knowledge about the antidepressant than that of patients with less knowledge (most of understanding(1.21±1.09),part of understanding(0.54±1.32),hardly understanding(0.33± 1.63) ,F=3.69,P<0.01) . The score of BMQ-s was higher in TRD patients without side effects of antidepres-sant than those with side effects ((1.04±1.24),(0.19±1.35),t=2.96,P<0.01). ②Stepwise multivariate linear regression analysis showed that payment methods,knowledge about the antidepressant,stigma about the antidepressant and episodes of depression were the influencing factors of BMQ-S in patients with TRD( all P<0.01) . Conclusion Different demographic characteristics and clinical features have different beliefs about antidepressant medication in patients with TRD.The payment methods,knowledge about the antidepressant, stigma about the antidepressant and episodes of depression are the influencing factors of BMQ in patients with TRD.
ABSTRACT
Objective To review the research progress of functional magnetic resonance imaging in Self -referential Processing (SRP) of patients with Depression based on the papers published from 2004 to 2014 at abroad and domestic,with an attempted to explore the neuromechanism of depression and to provide reference for treatment of depression.Methods Major online database including PubMed,EBSCO,Ovid,Medline,Clinicalkey,Wan Fang,CNKI,Cqvip,and CBM date bases were searched in Octobor 2014.The key words we used are depressionor depressive disorder,Self-referential Processing or rumination orautobiographical memory or Self-face recognition, Functional Magnetic Resonance Inaging(tMRI)and so on.Results 28 studies were adopted in this study,findings from the study showed:①rumination,autobiographical memory (AM) retrieval,and self-face recognition(SFR) are SRP paradigms,the cortical midline structures (CMS)and default mode network (DMN) were involved in the SRP of depression.②Both medication and cognitive behavioral therapy could reduce the abnormal activation of CMS and DMN in patients with depression.Conclusioins ①Both CMS and DMN may be the neuromechanism of SRP of depression.②Both CMS and DMN may be used as objective indicators to evaluate the treatment response in patients with depression.
ABSTRACT
Objective To investigate the effectiveness of glucocorticoids in the treatment of granulomatous lobular mastitis (GLM), and to discuss the optimal stage to add glucocorticoids during the treatment. Methods Twenty-four patients having received the core needle biopsy were involved. Ten cases with the explicit pathological diagnosis received the glucocorticoids therapy following the subtotal excision after remission. Pathological diagnoses of the rest 14 patients were undefined. For these 14 patients, simple partial excisions were given and the postoperative pathological diagnoses were presented as the GLM. Of all the 14 patients who accepted the surgical treatment firstly, 8 patients received the postoperative glucocorticoids adjuvant therapy. For the rest 6 patients, steroid hormone therapy was not used after surgery, and they were followed up postoperatively. All patients' clinical and pathological information were collected and analyzed. Results All patients were followed up for 6-36 months (average 18) by the outpatient service. Of all the 10 patients who received the glucocorticoids therapy before surgery, only 1 patient of them got the GLM recurrence. For the 8 patients who received the postoperative glucocorticoids treatment, only 1 patient got the recurrence. For the 6 patients who received simple partial excision, the recurrence of the GLM may be up to 3. There was no statistical difference between the two groups who both received the 05). But compared with the pure surgery treatment, the difference was obviously (P<0.05). Conclusions The clinical presentation and imaging performance of GLM are unspecific, so the diagnosis of the GLM is difficult. There is no consensus regarding the optimal treatment for GLM. The glucocorticoids therapy may be necessary preoperatively or postoperatively. For the patient with clear preoperative biopsy diagnosis, preoperative glucocorticoids adjuvant chemotherapy followed by the wide excision may be an effective method.
ABSTRACT
Objective To explore the difference of autobiographical memory (AM) between depressive patients with and without alexithymia,and correlation between AM and alexithymia in depressive patients with alexithymia.Methods 29 depressive patients with alexithymia,34 depressive patients without alexithymia were enrolled.All patients were measured by autobiographical memory test (AMT),Toronto alexithymia scale-20 (TAS20),Hamilton depression scale-24 (HAMD-24).Results ①The negative overgeneral AM score was higher in depressive patients with alexithymia than those without alexithymia ((3.34± 1.80),(2.51 ± 1.12),respectively t=2.19,P＜0.05).②The total overgeneral AM score was higher in depressive patients with alexithymia than those without alexithymia ((6.14±2.44),(4.86±2.06),respectively t=2.21,P＜0.05).③)The correlation coefficient (r value) between the total score of overgeneral AM and total score of TAS,TAS-Ⅲ scores of TAS in depressive patients with alexithymia were significantly positively correlated (r=0.240～0.611,P＜0.05).However,the correlation coefficient between the total score of specific AM and total score of TAS,TAS-Ⅲ scores of TAS in depressive patients with alexithymia were significantly negatively correlated(r=-0.502～-0.205,P＜0.05).Conclusion Compared with depressive patients without alexithymia,the overgeneral AM in depressive patients with alexithymia is more severe,and the alexithymia can increase the severity of overgeneral AM.

ABSTRACT
Object To explore the difference of overgeneral autobiographical memory (OGM) between first-episode and recurrent depressive patients,and whether the overgeneral autobiographical memory can affect the symptoms of depression or not.Methods 34 first-episode depression patients and 31 recurrent depression patients were enrolled.All patients were measured by autobiographical memory test (AMT),Hamilton Depression Scale-17 (HAMD-17) and Beck depression rating scale(BDI).Results ①The OGM score was higher in recurrent depressive group than that in first-episode group (respectively,(3.90 ± 1.65),(3.10± 1.57),t =2.035,P＜0.05).②The positive OGM score was higher in recurrent depressive group than that in first-episode group(respectively,(2.40± 1.36),(1.70± 1.08),t =2.308,P＜ 0.05).③The correlation coefficient (r value) between the total score of OGM and total score of BDI,total score of HAMD,two subfactors (cognitive disorder and slow)scores of HAMD in recurrent depressive group were 0.497,0.552,0.631,and 0.553 respectively,which significantly correlated.Conclusion Compared with first-episode depressive patients,the OGM in recurrent depressive patients is more severe.The OGM can increase the symptoms of depression,the cognitive disorder and slow.
ABSTRACT
Translational medicine is an emerging idea in current medical research area. Typically, for the purpose of bridging the gap between basic and clinical research, it not only emphasizes the urgency and necessity to break the traditional working formats, including single subject centered research team and limited cooperation among different scientific groups, but also highlights a more close and frequent interaction between basic scientist and clinician. In order to reach this goal, the theory and method of systems biology should be employed. This paper mainly focused on a central issue that how to carry out an investigation on early clinical diagnosis of xenobiotic-induced intrauterine growth retardation (IUGR) by using research concept of translational medicine and method of systems biology. Briefly, a hypothesis of common mechanism of IUGR was first proposed and subsequent validation was performed via integrating--omics (e.g. genomics, proteomics, cytomics, metabonomics/metabolomics) and molecular biology techniques. Metabonomics was further utilized to explore IUGR biomarker and establish preliminary forecasting model by bioinformatics and computational biology, which is available for early diagnosis of IUGR and make a complement to current evaluation criteria.
ABSTRACT
Objective To compare the hemodynamic responses to orotracheal intubation during emergency operation with the proseal laryngeal mask airway and endotracheal Intubation.Methods Fifty six patients who were ASA GRADE Ⅰ-Ⅱ before onset undergoing orotracheal intubation were randomly dirideed into either without laryngoscope direct proseal laryngeal mask intubation(PLMA) group or direct laryngoscope endotracheal intubation(TT) group.SBP、DBP、HR and SpO2 were recorded before,durring and 5 minutes after intubation.Intubation time and first attempt insertion success rate were recordeddso.All patients were followed up postoperatively for adverse effects like sore throat or hoarseness.Results In intubation time、first attempt insertion success rate and adverse effects like sore throat or hoarseness,PLMA group was 96.43%,(19.7?5.7)s and 7.1%,TT group was 100%,(27.9?11.3)s and 39.29%.Intubation time was significantly shorter and adverse effects like sore throat or hoarseness were lower in the PLMA group than TT group(P
