ObjectiveTo investigate the expression of TESTIN gene in endometrial carcinoma and explore the functions of this gene in tumor development and progression.MethodsqRT-PCR and immunochemical staining assay were used to determine the mRNA and protein level of TESTIN in the tumor tissues,and the relationship between TESTIN expression and clinical pathology characteristics was analyzed.Results Compared to normal tissue,76.5％ (52/68) tumor tissues showed TESTIN reduced ( P ＜ 0.01 ),furthermore,this reduction in the subgroup of endometrioid adenocarcinoma was significant,but it was rarely observed in the subgroup of serous papillary adenocarcinoma.ConclusionsTESTIN was obviously down regulated in endometrail carcinoma,especially in endometrioid adenocarcinoma,which indicated TESTIN played an important role in tumorigenesis of uterine.

Objective To discuss the influence of electroacupuncture (EA) on blood fat and volume of cerebral infarction in rats with hyperlipidemia complicated by cerebral ischemia,and explore the mecha-nism. Methods SD rats (n=78) were randomly divided into normal group (n=6), and model group, sham-operation group,EA group 1 and EA group 2(each n=18). Except of normal group,other groups were given high fat diet for 6 weeks for establishing hyperlipidemia model. After 6 weeks, EA group 1 was given EA in bilateral Fenglong(ST40) once a day for 7 d. On the 50thd,the model of middle cere-bral artery occlusion (MCAO) was established in alll groups except of rormal group,and then EA group 1 and EA group 2 were given EA in Baihui (GV20) and bilateral Fenglong (ST40) once a day. The neurological function and volume of cerebral infarction were detected 1 d after treatment. The levels of to-tal cholesterol (TC), triglyceride (TG), high-density lipoprotein (HDL) and low-density lipoprotein (LDL) were detected 1 d,7 d and 14 d after treatment. The protein expressions of β-NGF and TrkA were detected by using Western blotting assay in diseased brain. Results The levels of TC, G and LDL increased and level of HDL decreased after treatment (P <0.01, P <0.05). Compared with model group,level of TG decreased in EA groups after treatment for 7 d (P<0.01), and level of LDL de-creased in EA group 1 after treatment for 14 d (P <0.05), which had no significant in EA group 2. Compared with model group,neurological deficit score (NDS) decreased in EA group 1 after treatment for 1 d (P<0.05),and left volume of cerebral infarction decreased in EA groups (P<0.01), which was smaller in EA group 1 than that in EA group 2(P<0.05). Compared with normal group, expres-sions of β-NGF and TrkA had an ascending trend in model group after treatment for 1 d,and recover to normal after treatment for 7 d. Compared with model group,expressions of β-NGF and TrkA had an as-cending trend in EA group 1 and continuously increased after treatment for 14 d,which was more signifi-cantly in EA group 1. Conclusion EA can improve neurological function,reduce volume of cerebral in-farction and promote expressions of β-NGF and TrkA through regulating blood fat level in hyperlipidemia stage,and its regulation effect is better than that of acupuncture after cerebral ischemia. The possible mechanism is related to that GV20 and ST40 can cmprove expressions of β-NGF and TrkA.

Objective:To investigate the clinical characteristics, surgical methods, complications and prognosis of children younger than 1 year old who had definite epileptogenic lesions under 1 year old.Methods:A total of 14 children with definite epileptogenic lesions and underwent radical surgery in Pediatric Epilepsy Center of Peking University First Hospital from March 2017 to July 2019 were selected.Their clinical data including operation age, course of disease, etiology, physical examinations, seizure types, seizure frequency, features of interictal electrocorticography(EEG), surgical methods, antiepileptic drugs, and pathology were collected and analyzed.Postoperative efficacy was eva-luated using Engel grading.The Griffiths neurodevelopmental scale and the Peabody motor developmental scale were used to assess motor neurodevelopment.Results:The operation age of 14 children was 119 to 358 days (median: 281 days), and the course of disease ranged from 119 to 352 days (median: 266 days). The age of onset was from 0 to 135 days was (median: 7.5 days), and the postoperative follow-up time was 0.5-2.0 years(median: 1.5 years). None of the patients had seizure recurrence at the last follow-up.During the follow-up period, 1 patient had recurrence, but deve-loped no seizures anymore after drug administration.Cognitive and motor functions improved during follow-up in all children.All the children had no serious complications such as postoperative infection and hydrocephalus.Conclusions:Young children with definite epileptogenic lesions have an early onset of seizures, which has a great influence on development.Multidisciplinary preoperative evaluation shows that surgery is a safe way to terminate progression of seizures, thus helping children to well develop and reducing the use of antiepileptic drugs.

Objective:To explore the clinical manifestations and surgical outcomes of pediatric epilepsy patients with epileptic spasms (ES) as the main form of seizure, so as to analyze the correlative factors with prognosis and improve the understanding of the operation and preoperative positioning for such patients.Methods:The clinical data of patients with ES who underwent surgery therapy from June 2014 to December 2015 in Pediatric Epilepsy Center, Peking University First Hospital were collected and retrospectively analyzed.Demographic characteristics, seizure forms, etiology, electroencephalogram (EEG), cranial magnetic resonance imaging (MRI), operative methods, pathological findings as well as surgical outcomes evaluated by Engel classification during follow-up of the subjects were collected.Correlative factors with the prognosis were explored by comparing the data between patients with optimal outcome (Engel Ⅰ) and those with poor outcomes (Engel Ⅱ-Ⅳ).Results:A total of 25 pediatric patients were enrolled, including 16 males (64.0%) and 9 females (36.0%). The age of onset was (0.81±0.68) years, the age at operation was (2.98±1.63) years, and the course of disease was (2.17±1.48) years.Besides, 84.0% (21/25 cases) of the ES patients had multiple forms of seizures and partial seizure (19 cases) was the most common.MRI of the heads of all the children showed definite lesions, including 11 patients (44.0%) with lesions limited to one brain lobe and 14 patients (56.0%) involving multiple brain lobes or hemisphere.The most common etiology was focal cortical dysplasia (13 cases), followed by intracranial developmental tumors (3 cases). All patients underwent resection surgery, including resection of lesion (3 cases), single brain lobe resection (9 cases), multiple brain lobe dissection (3 cases) and hemisphere dissection (10 cases). During a follow-up period of 4.0 to 5.5 years, 1 patient was lost.Among the remaining 24 cases, 18 (75.0%) cases achieved good outcomes and wee classified as EngelⅠ, 2 cases (8.3%) and 4 cases(16.7%) were classified as Engel Ⅱand Ⅳ, respectively.The univariate comparison between the good epilepsy prognosis group and the poor epilepsy prognosis group showed that, patients whose EEG abnormalities are consistent with the anatomical lesions during the inter ictal tend to have good prognosis( P=0.006). Conclusions:(1) Optimal therapeutic effects were observed in ES patients with definite lesions treated by surgical therapy.(2) Interictal EEG consistent with the lesion side may suggest a good prognosis for surgical treatment.(3) Structural causes should be screened as soon as possible if a patient with ES is drug-refractory and presents clues of focal origin.
