Ovarian endometrioma is a common form of endometriosis, which may cause infertility, dysmenorrhea and pelvic pain in women of reproductive age. Although surgery is the treatment of choice for endometriomas, recurrence poses a formidable frustration. This study investigated potential risk factors of endometriomas recurrence, aiming to better understand its pathogenesis. A total of 307 patients with endometriomas were followed up for an average of 28.6 months and the 1-, 2- and 3-year cumulative recurrence rate was 9.5%, 21.9%, and 29.2%, respectively. Twenty-one potential risk factors for endometriomas recurrence were evaluated using Cox's proportional hazards models. Total revised American Fertility Society (rAFS) score was significantly associated with higher recurrence (OR=1.858, 95% CI=1.122-3.075, P=0.016), as well as younger age at surgery (OR=0.953, 95% CI=0.915-0.992, P=0.020). Semiradical surgical treatment was defined as surgical removal of cyst plus hysterectomy with preservation of bilateral or unilateral ovary, and was a significant factor that was associated with lower recurrence than the conservative surgery (OR=0.318, 95% CI=0.107-0.951, P=0.040). Postoperative pregnancy was favorable factors for disease recurrence (OR=0.217, 95% CI=0.102-0.460, P=0.000). The results suggest that endometrioma recurrence is inversely associated with age at surgery and postoperative pregnancy, and may correlate with total rAFS score and conservative surgery method.

Objective To explore the behavior and initial sandtray characters of the children with oppositional defiant disorders (ODD) in order to provide psychological and behavioral intervention as early as possible.Methods The differences of the Conners parent symptom questionnaire (PSQ) and initial sandtrays between 24 children with ODD and 24 normal children were compared.Results PSQ indicated that children with ODD had higher scores of conduct proble((1.31 ± 0.53),(0.36 ± 0.31)),learning problem ((2.01 ± 0.66),(0.57 ±0.5)),hyperactivity-impulsion ((1.60 ± 0.77),(0.35 ± 0.41)),anxiety ((0.60 ± 0.50),(0.27 ± 0.25)) and hyperactivity index((1.12 ± 0.31),(0.78 ± 0.28)) than normal children.On the use of toys,the experimental group was significantly higher in armament and transports and lower in plants and stones(P＜0.05).On the theme of sandtrays,the ODD group was significantly higher in disorder,neglect,injury,threat and lower in integration and energy (P ＜ 0.05).Conclusion The results show that the children with ODD have more anxiety experience than normal children and this may be associated with oppositional conduct.Children with ODD use more aggressive toys and wounded themes,revealing their attack and conflict.Psychological intervention can be provided according to the characters of behavior scale and initial sandtray.

Objective To investigate pathological mechanism of dysfunction of executive control in children with attention-deficit hyperactivity disorder (ADHD) ,using a new resting-state functional magnetic resonance imaging(fMRI) index, fractional amplitude of low frequency fluctuation (fALFF). Methods Thirty children of school age with ADHD and thirty gender, age and education-matched healthy controls were experienced restingstate fMRI scans. fALFF approach was used to analyze blood oxygen level-dependent fMRI(BOLD-fMRI) data in resting state. Results Compared with the normal controls,the ADHD showed decreased fALFF in the bilateral superior frontal gyrus( BA10, t=5. 40,4.11 ,Z =4.81,3.82),bilateral middle frontal gyrus( BA9,BA46, t=5.72,5.37, Z = 5.04,3.08 ), right medial frontal gyrus ( BA 10, t = 5.53, Z = 4.90 ) and left precuneus ( t = 3.81, Z =3.57). And the ADHD showed increased fALFF in the bilateral limbic lobe (BA36, t = 4.37,5.20, Z = 4.02,4.66 ), right brainstem ( t = 4.77, Z = 4.34) and bilateral cerebellum ( t = 4.65,4.83, Z = 4.24,4.38 ). Conclusion The results suggest that lower activition of frontal may be the core deficit of executive control with ADHD in resting state,and high activation in several brain regions may be related to compensatory effect.

ObjectiveTo explore the particular inner world of the children with attention deficit hyperactivity disorder (ADHD)with the sandplay therapy and the initial sandtray's clinical diagnosis role and value on the ADHD.MethodsThe differences of the initial sandtrays between 28 children with ADHD and 24 normal children were compared.Results 1.On the use of toys,the experimental group was significantly higher in transports ((5.04 ±6.60),(1.38 ±2.12),t=2.73) and lower in stones((0.00 ±0.00),(8.00 ± 12.33),t=-3.18).2.On the scene of sandtrays,the experimental group was significantly higher in the fight( x2 =12.96,P ＜ 0.01 ),dynamic scenes ( x2 =13.37,P ＜ 0.01 ).3.On the use of self-images,the experimental group was lower than the normal children,and the differences were significant ( x2 =4.75,P ＜ 0.05 ).4.There were no significant differences in the use of sand between two groups( x2 =3.46,P ＞ 0.05).ConclusionThe results show that the children with ADHD have significantly characteristics in sandtrays.Initial sandtray is valuable to be an aid to clinical diagnosis and intervention means.

ObjectiveTo investigate the difference of the spontaneous neuronal activity between attention-deficit hyperactivity disorder (ADHD) and normal children with amplitude of low-frequency fluctuation (ALFF) of the resting-state fMRI,and to discuss the correlation between the activity level of brain and symptom severity.MethodsThirty-two children with ADHD of school age and thirty age-and gender-matched controls were experienced with resting-state fMRI scans while blood oxygenation level dependent (BOLD) signal was acquired to calculate the amplitude of low-frequency fluctuation (ALFF).Linear correlations were performed between the aggregate score of RS-Ⅳ and ALFF voxels in ADHD patients.ResultsCompared to the controls,the ADHD group exhibited decreased ALFF in right superior frontal gyrus ( BA9,t =- 4.61 ),left superior medial frontal gyrus ( BA10,t =- 3.63 ),left mediate frontal ( BA46,t =- 4.09 ),and left anterior cingulate cortex ( BA24,t =- 4.02).Meanwhile,it showed increased ALFF in the medial orbitofrontal cortex( BA11,t =3.52 ),right cuneus gyrus ( t =3.93 ),right mediate occipital gyrus ( BA 19,t =3.82),right cerebellum ( BA37,t =3.77),right mediate temporal gyrus( BA37,t =3.76),and left paracentral lobe ( BA6,t =3.77 ).Altered ALFF in left superior medial frontal gyrus(P=0.009,r=0.492)and the right cuneus gyrus(P=0.024,r=0.433) showed correlation with the aggregate score of RS-Ⅳ.ConclusionThe spontaneous neuronal activity decreases in prefrontal cortex and increases in default mode network of ADHD group,the activity level of left prefrontal and right cuneus gyrus is positively correlated with symptom severity.

Objective To investigate the risk factors which indicate behavior problems and degree of conflict function defects in different subtypes of attention deficit hyperactivity disorder( ADHD),and to compare behavioral problems,family environment and conflict function in children with and without ADHD.Methods 87children with ADHD and 38 matched controls performed Simon-Stroop task while questionnaires (Parent Symptom Questionnaire and Family environment Scale)were acquired from their parents.Results Questionnaire indicated that children with ADHD-combined(ADHD-C) had the highest score of conduct problem( 1.05 ± 0.44),learning problem ( 1.97 ± 0.52 ),hyperactivity-impulsion ( 1.56 ± 0.60) and hyperactivity index ( 1.45 ± 0.40 ) than ADHDⅠ(0.65±0.32,1.58 ±0.58,1.06 ±0.46,1.01 ±0.31) and matched controls ( 0.42 ±0.24,0.77 ±0.49,0.58±0.40,0.55 ±0.34) in PSQ.ADHD-Ⅰ and ADHD-C had higher score of contradiction(3.28 ± 1.70,4.61 ±2.56 ) and lower score of family cohesion (6.75 ± 2.27,6.61 ± 2.03 ),emotional expression (5.03 ± 1.54,5.06 ±1.91 ),knowledge (3.83 ± 2.30,3.61 ± 1.81 ) and entertainment (3.70 ± 2.12,3.47 ± 2.32 ) than matched controls (2.36 ± 1.44,8.06 ± 1.71,6.03 ± 1.54,4.86 ± 1.91,4.83 ± 2.29) in FES-CV.Behavior data indicated that the correct rate of children with ADHD-Ⅰ and ADHD-C in Simon-incongruent trials( Siin:0.76 ± 0.13,0.69 ±0.13 ) and Stroop-inconsistent trials( Stin:0.82 ± 0.10,0.78 ± 0.08 )were lower and reaction time of children with ADHD-Ⅰ and ADHD-C in the Siin ( (876.4 ± 97.34) ms,( 893.8 ± 130.1 ) ms) and Stin ( ( 864.4 ± 91.82 ) ms,(860.2 ± 125.0) ms) were longer than matched controls ( (Siin (0.81 ± 0.11 ) ms,(810.4 ± 136.1 ) ms; Stin (0.87 ± 0.08 ) ms,(797.4 ± 136.1 ) ms).Pearson correlation analysis suggested that some factors in the FES-CV had correlation with behavioral problems.Conclusion This finding indicates that poor family environment is the risk factor that indicate behavioral problems in children with ADHD and behavioral problems,conflict function defeet of ADHD-C are more serious than ADHD-Ⅰ and matched controls.

Objective To compare the event-related potential(ERP) difference waveforms between attention deficit hyperactivity disorder (ADHD) children and normal children in the conflict task,and to investigate the neural mechanism of conflict monitoring of ADHD. Methods ERPs elicited by performing the spatial SimonStroop task were recorded in 32 children with ADHD and 32 normal children. The differences of ERP and behavior dren with ADHD(0.80±0. 11 ,0.87 ±0.08) were less than normal children (0.88 ±0.07,0.93 ±0. 04)in Sireaction time of ADHD group( (773.03 ±99.34)ms) in the Siin were longer than the control group( (737.21 ±81.40)ms) ,the differences had statistic significance (P＜0. 05). 2. ERP results:the amplitude of N2 of the children with ADHD in the four conditions were smaller than the control group, the difference in Siin had statistic sigof prefrontal and anterior cingulate cortex of ADHD were weaker than the control group. Conclusions The results suggest that, due to the inadequate allocation of attention resources of the children with ADHD, they have conflict monitoring function defects compare with normal children. The function defects of conflict information processing related brain areas may be the main neural mechanism. The result of the behavior and ERP can become the reference indicator for the early diagnosis and treatment of ADHD.
