Attention-deficit/hyperactivity disorder (ADHD)is one of the most common comorbidities of ASD.This article reviews the assessment tools and clinical research (prevalence,clinical characteristics and treat-ment)and fundamental research (iconography,genetics,neurophychology,electronerophysiology)of ASD with ADHD according to lately related articles.The findings suggested that there was lack of researches on treatment and iconography of ASD with ADHD and the conclusions were inconformity.Furthermore,most of the objects in these researches were children of normal intelligence.Thus future research should expand its objects to patients of adult and children with mental retardation and do further explore in iconography and treatment.

Objective To describe the sonographic appearance of mesenchymal hamartoma of the liver(MHL)and to analyze the diagnostic value of ultrasound.Methods Eleven surgically and pathologically confirmed cases of MHL from January 2005 to May 2011 in the Beijing Children′s Hospital were retrospectively reviewed.Results Ultrasound examinations showed 9 cystic hamartomas,including 7 multiseptate cystic and 2 monocystic lesions.Of the 7 multiseptate cystic hamartomas,4 had a honeycomb appearance and 3 had irregularly-distributed multiple cysts with varied septations.Of the 2 monocystic hamartomas,1 had a large cystic portion while the other was mainly solid with approximately 4% cystic portion of the tumor.Two cases in this group were solid,presenting with a well-defined homogenous mass.Conclusions Ultrasonography is an effective imaging modality for the diagnosis for MHL.A mixed or a mainly-cystic liver mass found in a child less than 2 years old should be suspicious for MHL.

Objective To preliminarily evaluate the value of color power doppler ultrasonography in the diagnosis of sacroiliitis in ankylosing spondylitis(AS). Methods Fifty-seven sacroiliac joints in 31 patients with active AS and 40 sacroiliac joints in 20 volunteers were detected by color power doppler ultrasonography.The color flow signs inside the sacroiliac joints were observed,and the resistance index(RI) was measured. Results In active AS,color flow signs were seen in 55 joints,and the mean RI value was 0.53?0.08 in 45 joints,while the other 10 color flow signs represented reversed phase in diastolic phase on pulse doppler ultrasonography.In the volunteers,color flow signs were seen in 16 joints,and the mean RI value was 0.97?0.01 in 6 joints,while the other 10 color flow signs represented reversed phase in diastolic phase on pulse doppler ultrasonography. Conclusion The abnormal flow signs at the sacroiliac joints can be detected by color power doppler ultrasonography.Low RI values provide diagnosis evidence for active AS.

Objective To evaluate the influences of FBP and OSEM (with different iteration numbers or subset numbers) on cardiac function parameters with MPI,and to identify a suitable clinical method.Methods The MPI of 66 patients (33 males,33 females,age range: 18-77 years) from January 2012 to December 2014 were retrospectively analyzed.The imaging data was reconstructed with FBP and 5 different OSEM (4-16 subsets and 2-4 iterations) in order to evaluate if there was any difference of cardiac function parameters calculated by QGS between the different image processing methods.In addition,the results were compared with those of cardiac ultrasonography.One-way analysis of variance was used for data analysis.Results The statistical differences of LVEF,EDV,and ESV(F values: 10.73,4.89 and 5.97,all P<0.05) were found among 6 reconstructed methods.The values of LVEF were (66.14±11.12)％,(75.05±12.10)％,(70.09±11.27)％,(66.88±10.38)％,(64.97±10.25)％,and (62.58±9.84)％.Those of EDV were (77.32±27.58),(67.97±27.56),(75.10±27.89),(81.03±28.11),(84.94±29.07),and (89.98±29.71) ml,and the ESV values were (28.71±10.04),(19.71±16.51),(25.13±17.66),(29.01±18.47),(32.10±19.63),and (35.83±20.41) ml respectively.The cardiac function parameters measured by OSEM (with 2 iterations,12 subsets) were much similar to that measured by cardiac ultrasonography.Conclusion Compared with other 5 processing methods of MPI,the OSEM (with 2 iterations,12 subsets) method may be more suitable for practical clinical application.

The aryl hydrocarbon receptor (AhR) is a ligand-activated transcription factor that regulates gene expression in a range of cells, including immune and epithelial cells. AhR signaling plays important roles in the immune system in both health and disease states. Tapinarof is a first-in-class small-molecule topical therapeutic AhR modulating agent launched for the treatment of psoriasis. To improve the activity and chemical stability of Tapinarof, a series of 2-phenylchromen-4-one derivatives were designed, synthesized and evaluated as novel AhR agonists. Compounds 5a, 5c, 5e and 5f potently activated AhR with an EC₅₀ value of 7, 9, 6 and 6 nmol·L^-1, respectively, which are 10-14 fold more potent than Tapinarof. Compounds 5a and 5e exhibit comparable inhibitory effects on IFN-γ production as Tapinarof. Furthermore, compounds 5a-5f exhibited favorable photochemical stability compared to Tapinarof. The compounds may eventually serve as lead compounds for the development of new AhR agonists.

Untargeted metabolomics analysis of rhubarb and stewed rhubarb samples shows that the determined samples clearly clustered in to two groups, indicating that the processing procedures caused changes in the composition and/or content of components in rhubarb. Ten components were identified by UHPLC-Q-TOF-MS/MS and references, which intensity declined in rhubarb after processing. Targeted metabolomics analysis of rhubarb and stewed rhubarb samples indicated that aloe-emodin, rhein, emodin and physcion were detected with lower intensity in stewed rhubarb samples than in rhubarb samples. Metabolomics analysis of rhubarb and stewed rhubarb indicated the various components of rhubarb changed after processing.

Objective To evaluate the influence of gestational diabetes mellitus (GDM) on maternal and perinatal outcomes in twin pregnancies. Methods We retrospectively analyzed the clinical features of both twin and singleton pregnancies, which delivered in Guangzhou Women and Children's Medical Center between January 1, 2012 and December 31, 2013. The twin pregnancies were divided into two groups:those with (GDM-T, n=51) and without GDM (non-GDM-T, n=130), which were matched by maternal age and delivery time (within one month) in a ratio of 1∶2 among singleton pregnancies with (GDM-S, n=102) and without GDM (non-GDM-S, n=102), respectively. The differences of adverse maternal and perinatal outcomes among these four groups were examined. The overall assessment of pregnancy outcomes was completed using Delphi method. Statistical analysis was performed with one-way analysis of variance, t test, Kruskal-Wallis test, rank test, Chi-square test or Fisher's exact test. Results (1) When compared to GDM-S and non-GDM-S group respectively, less women conceived with the help of assisted reproductive technology, higher proportion of women underwent and gestational age at delivery tend to be earlier in GDM-T and non-GDM-T group (all P<0.01). In oral glucose tolerance test,the fasting blood glucose level of GDM-T group was higher than the other three groups (F=21.716, P<0.01), the glucose levels at 1 and 2 h were higher than non-GDM-T and non-GDM-s respectively (both P<0.01), but no significant difference was found when compared with GDM-S group (P>0.01). Similarly, no significant difference was found in prenatal glycosylated hemoglobin value between GDM-T and GDM-S group (P>0.01). (2) There was no significant difference in the incidences of hypertensive disorders of pregnancy, anemia, premature rupture of membranes, oligohydramnios, placental abruption, postpartum hemorrhage, asphyxia neonatorum, small for gestational age, hypoglycemia of newborn, hyperbilirubinemia of newborn and perinatal death between GDM-T group and the other three groups(all P>0.01). Higher incidences of hypertensive disorders of pregnancy and postpartum hemorrhage were shown in the GDM-T group than in the GDM-S and non-GDM-S groups, respectively (both P<0.01). The incidences of preterm birth in GDM-T and non-GDM-T group were both higher than that in GDM-S and non-GDM-S, respectively [54.9%(66/102), 53.8%(140/260), 5.0%(10/102) and 3.0%(6/102), all P<0.01], while no significant difference was found between GDM-T and non-GDM-T group (P>0.01). (3) The overall assessment of pregnancy outcomes did not show any difference between GDM-T group and the other three groups (χ2=6.707, P>0.01). However, the score for fetal outcomes in the GDM-T group was higher than in the GDM-S and non-GDM-S group, but lower than in non-GDM-T group [M(Q)=1.0(2.3), 0.0(3.0), 0.0(0.0), 1.0(2.8) score, χ2=122.818, P<0.01]. Conclusions GDM does not increase the risk of adverse pregnant outcomes in twin pregnancies.

Objective To evaluate the medium-term outcomes of minimally invasive percutaneous nephrolithotomy in patients with renal function impairment.Methods Data of 811 patients who underwent minimally invasive percutaneous nephrolithotomy between Jan.2009 and Dec.2011 were retrospectively collected.Seventy-eight patients had a preoperative estimated GFR of 30-59 ml/(min · 1.73m2).The minimum follow-up was 1 year.Patients were divided into group 1 (improved or stable disease) and group 2 (worsened disease).Patient age was (42.8 ± 16.3) and (45.3 ± 14.2) separately,with male patients 41 and 7,female patients 25 and 5 respectively.Body mass index were (24.3 ± 4.1) kg/m2 and (25.4 ±5.2) kg/m2,history of open surgery or ESWL were 19 and 4.Mild hydronephrosis were 22 and 4.Staghorn stone were 22 and 5.Multiple access were 13 and 2.Operative time was (78.2 ± 30.4) min and (80.3 ±32.3) min.Stone-free rate 1 month postoperatively were recorded.Multiple regression analysis was used.Results The stone free rate at 1 month postoperatively was 85％ by CT scan.Preoperative eGFR was (38.4±12.8) ml/(min · 1.73m2),and 1 ycar postoperative eGFR was (45.1 ±15.8) ml/(min · 1.73m2)in 78 patients.Renal function had improved in 31％ of patients,but it remained the same or deteriorated in 54％ and 15％,respectively at 1 year follow-up.On multivariate regression analysis,diabetes was associated with the deterioration of renal function.Conclusions At medium-term follow-up,renal function was maintained or improved in 85％ of patients with chronic kidney disease who underwent minimally invasive percutaneous nephrolithotomy.Minimally invasive percutaneous nephrolithotomy could be an effective and safe option for the patients with chronic renal function impairment.Diabetes mellitus was independent predictive factor of renal function impairment.Therefore,patients with diabetes should be followed up carefully.Medical management is needed if necessassry.

Objective To investigate the effects of fast-track surgery on postoperative rehabilitation of patients with liver cancer. Methods Forty-one patients with liver cancer who had been admitted to Zhongshan Hospital of Fudan University from 9 to 30 in July 2008 were randomly divided into fast-track surgery group (n =20) and routine treatment group (n =21) according to the random number table. Patients in fast-track surgery group were preoperatively educated in order to lessen their anxiety. Bowel preparation was not applied before operation, and they were orally administered with 1000 ml of enteral nutrition emulsion (1300 kcal), then they were fasted for 4 hours before operation. Urethral catheter and gastric tube were removed after operation. They were orally administered with 1000 ml of enteral nutrition emulsion on postoperative day 2, and were encouraged to partake in off-bed activity shortly after the operation. The off-bed time, anus exhaust time, postoperative complica-tions, hospitalization time, expense, nutritional and metabolic indexes on postoperative day 1, 3 and 5, hepatic and renal function, immune and stress indexes between the 2 groups were compared by t test and chi-square test. Results There were significant differences in off-bed time, anus exhaust time, patients' weight, expense, total bilirubin level on postoperative day 1, 3 and 5, and level of serum TNF-α on postoperative day 3 between the 2 groups (t =7.065, 5.483, 3.754, 2.291,2.289, 3.218, 3.192, 2.434, 2.089, P <0.05). Conclusions Fast-track surgery can accelerate the postoperative rehabilitation of patients with liver cancer.
