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 explore the features of clinicopathology,gastroscopy,endoscopic ultrasonography (EUS) and immunohistochemistry of esophageal mesenchymal tumors (EMT).Methods The clinical data of 98 cases of EMT patients who underwent endoscopic biopsy,endoscopic treatment or surgery and were diagnosed according to pathological and immunohistochemistry examination were collected.The clinicopathologic characteristics,endoscopy,EUS and immunohistochemistry of these cases were retrospectively analyzed,and differentiated from other submucosal tumor.Results Among the 98 cases of EMT,there were 77 leiomyomas (LM),15 gastrointestinal stromal tumors (GIST),four lipomas,one leiomyoblastoma and one schwannoma.The age of GIST group were older than that of LM group,and most were male patients predominated in these two groups.Dysphagia was the most common symptom of EMT.Gastrointestinal bleeding was rare,which was different from other gastrointestinal mesenchymal tumors.Under endoscopy,the appearances of EMT were similar,as submucosal protuberant lesions.One esophageal GIST was extraluminal lesion.Under EUS,LM,GIST and schwannoma showed low echo images originated from the muscularis propria or muscularis mucosa.Lipomas showed high echo images originated from submucosa.Pathological examination indicated that main cell type of LM and schwannoma was spindle cell,part of GIST was epitheloid cell type.The expressions of CD117 and CD34 were high in GIST,the expressions of SMA and Desmin were high in LM.S-100 was expressed in schwannoma.Other submucosal tumors,such as esophageal cyst,esophageal tuberculosis,esophageal carcinosarcoma,and some esophageal squamous carcinoma were easily misdiagnosed as EMT.Conclusions Esophageal LM is the most common EMT,followed by GIST.EUS is helpful in EMT diagnosis,however it can not accurately distinguish GIST,LM or schwannoma.

Objective To research the pathogeny and the electromyographic characteristics of myokymia.Methods The clinical features and electromyography of 42 elderly patients with myokymia were examined. Results Symptomatic myokymia (SM) in 27 cases was caused by low salt syndrome, thyrotoxemia, urinaemia, chronic wasting diseases (such as carcinoma of the stomach or liver), brachial plexus neuropathy, lead poisoning, chronic inflammatory demyelinating polyradiculoneuritis, succinylcholine narcosis, restless leg syndrome or Isaac's syndrome.Symptomatic facial myokymia was caused by neoplasm of the brain stem or in posterior cranial fossa, multiple sclerosis or other causes. Primary myokymia ( PM ) in 15 cases involved idiopathic generalized and benign myokymia.Compared with PM, SM was more constant and powerful. Myokymia potential appeared in the electromyograms of 42 of the patients. The majority of patients with SM had accompanying myotonic discharge. Conclusion The pathogeny and electromyographic characteristics of symptomatic myokymia are different from the primary stage.

OBJECTIVETo explore clinical results of open reduction and internal fixation (ORIF) for posterior Pilon fracture through posterolateral approach.

METHODSSeventeen patients with posterior Pilon fracture were treated through posterolateral approach from February 2010 to April 2013. Among them,including 11 males and 6 females aged from 29 to 59 with an average of 43.4 years old. All fractures were associated with more than 20% of articular surface of distal tibial. The causes of injury included falling down (11 cases), traffic accident (4 cases) and sports injury(6 cases). Fracture classification was based on posterior pilon fracture by YU Guang-rong, including type I (6 cases), type II (2 cases) and type III (6 cases). Fracture healing time, fracture reduction and postoperative complications were observed, AOFAS score were applied to evaluate clinical efficacy.

RESULTSAll patients were followed up from 13 to 24 months with an average of 20.5 months. All incisions were healed at stage I, and fractures obtained healing,the time of fracture healing ranged from 12 to 21 weeks with an average of 15.2 weeks. No incision infection, neurovascular injury, bone ununion and fracture deformity were found after operation. Postoperative AOFAS score was 92.0 ± 10.2, and 14 cases got excellent results, 2 good and 1 moderate.

CONCLUSIONPosterior pilon fracture through posterolateral approach could obtain effective reduction, stable fixation. It is a safe, simple and effective operation for treating posterior Pilon fracture, and it is worth popularizing.

The expressions of Ki67 and FHIT were detected by immunohistochemical staining in 15 cases of adrenocortical carcinoma, 42 cases with adrenocortical adenoma,6 cases of adrenocortical hyperplasia, and 10 cases of normal adrenocortical tissue. The results showed that the highest expression of Ki67 and the lowest expression of FHIT were found in adrenocortical carcinoma. There were significant differences in the Ki67 and FHIT between adrenocortical adenoma and adrenocortical carcinoma ( both P < 0. 05 ). There existed negative correlation between the expressions of Ki67 and FHIT( r=-0. 712, P<0.05 ). Ki67 over-expression and loss of FHIT expression may be involved in the occurrence and development of adrenocortical carcinoma. It is suggested that combined detections of Ki67 and FHIT may have reference significance in the differentiation of adrenocortical adenoma from adrenocortical carcinoma.

Objective To explore the differences and similarities of clinical characteristics,pathological features, treatment and prognosis between primary gastric lymphoma(PGL)and primary intestinal lymphoma (PIL). Methods The clinical characteristics, pathological features, therapeutic results, the detection of Helicobacter pylori (Hp) and prognosis of 48 PGL cases and 15 PIL cases were retrospectively analyzed. Results There was no statistical significance in age, gender, abdominal pain, gastrointestinal bleeding, B symptoms, clinical stage, mortality between PGL and PIL groups (P>0. 05). However, there were significant differences in the pathological type, acute abdomen emergency surgery between these two groups (P<0. 05). There was 12 Hp positive cases in mucosalassociated lymphoid tissue (MALT) lymphoma of PGL group (12/19), and 5 Hp positive cases in diffuse large B-cell lymphoma (DLBCL) (5/20). There was significant difference in Hp detection rate of these two pathological types. Hp was not found in PIL group. The Cox multivariate analysis indicated that stage Ⅲ-Ⅳ was the independent adverse factors affecting PGL prognosis (P<0. 05).Conclusions Mainly histological types are DLBCL and MALT lymphoma in PGL, and DLBCL in PIL.PIL predispose to T-cell lymphoma compared with PGL. MALT lymphoma is rare in PIL group. The mainly clinical stage is Ⅲ-Ⅳ both in PGL group and PIL group. Emergency surgery is often needed in PIL because of intussusception or perforation. The prognosis of PGL is correlated with the stage and the prognosis of PIL are correlated with the stage, B symptoms and T cell phenotype.

Objective To compare the effect of difierent combinatio of mannitol, furesemide and albumin in reducing intracranial pressure in 451 patients with severe traumatic brain injury (sTBI). Methods A total of 451 patients with an admissiou Glasgow Coma Scale of or less from 5 medical centers were randomly divided into 5 groups, ie, Group A(250 ml 20% mannitol each time as control), Group B(125 ml 20% mannitol each time), Group C(alternate use of 250 ml 20% mannitol each time or 40 mg furosemide), Group D(alternate use of 125 ml 20% mannitol each time and 20 mg furosemide)and Group E(alternate use of 125 ml 20% mannitol and moderate or large dose of albumin). We monitored intracraniai pressure continuously and observed the changes of intracranial pressure, electrolytes, hemato-crit and renal function after use of 5 combinations of mannitol. Furosemide and albumin. Results Man-nitol and furosemide could independently reduce intracranial pressure after 1-3 hours (P<0. 05). Semis mannitol plus furosemide or albumin could more signifieantly reduce intracranial pressure, with statistical difference compared with full dose of mannitol. Semis mannitol and alternate use of mannitol and furose-mide in aspect of intracranial pressure reduction and persistence time(P<0. 05). Alternate use of man-nitol and furosemide begot higher incidence rate of electrolyte abnormality, compared with the other com-binations (P<0. 05). Rebound rate of intracranial pressure was higher in full dose of mannitol than other combinations (P<0. 05). Incidence of renal function abnormality was higher in combination involved al-bumin than alternative use of mannitol and furosemide as well as combination of semis mannitol and furo-semide (P<0. 05). Abnormality of electrolyte and renal function wag reversible. Conclusion The use of 125 ml 20% mannitol each time plus 20 mg furesemide is more reasonable than other combina-tions. Meanwhile, semis mannitol combined with moderate or large dose of albumin has certain advantages too.

Objective To investigate the significance of quantitative thermal testing (QTT) in the diagnosis of diabetic peripheral neuropathy. Methods One hundred and sixty-nine diabetic patients with neurological deficit (DM group) and 53 age-matched healthy controls underwent the determination of cold threshold (CT), warm threshold (WT), clod pain threshold (CPT), warm pain threshold (WPT) in both dorsum of hand and dorsum of foot. DM group were divided into subgroups with a course of disease > 5 years or with a course of disease ≤ 5 years, or divided into subgroups with normal or abnormal nerve conduction study (NCS). Results CT and WT of DM group with a course of disease ≤ 5 years ((29.6 ± 1.4), (26. 5±4. 3) ℃ ; (35.9±3.0), (41.3±4. 0) ℃) were higher than the health controls' ((30. 2±1.2), (29.1±1.5) ℃; (35.0±1.9), (36.5±1.5) ℃, respectively; t=3.27, 6.63, 2.80, 8.61, all P< 0. 05). The CT and WT of DM group with a course of disease > 5 years' ((28. 2±4. 0), (23. 1 ±7.9) ℃ ; (37.0±4. 7), (42. 6±4. 2) ℃, respectively) were higher than the DM group with course of disease≤ 5 years(t =4. 09, 4.63, 2.55, 2. 68 ,all P <0. 05). CT and WT of the normal NCS group((29. 5 ± 1.8), (27.0±4. 6) ℃ ; (35.0±1.9), (40. 9±3. 8)℃, respectively) were higher than the healthy controls' , and the difference was significant(t =3.22, 4. 17, 3.51,9. 95,all P<0.01). The frequency of abnormal QTT in DM group was higher than that of NCS in DM group. The QTT and NCS of DM group with a course of disease >5 years were higher than these in DM group with a course of disease ≤5 years; the frequency of abnormal WT in DM group(86. 4% ,146/169)was higher than that of CT in DM group(68. 1% ,115/169,x2=15.49, P<0.01), the frequency of abnormal QTT in the dorsum of foot in DM group was higher than that in the dorsum of hand in the DM group. PT of diabetic patients were higher than that in the healthy controls. Condusions QTT is more sensitive than NCS in the diagnosis diabetic peripheral neuropathy, which is neeossary to assist NCS when diabetic peripheral neuropathy is suspected, WT in dorsum of foot is a sensitive parameter in the diagnosis of diabetic peripheral neuropathy.
