ObjectiveTo investigate the relationship between the clinical type of attack and electroencephalogram (EEG) features of cerebral palsy (CP) children with epilepsy (EP).MethodsThe EEGs of 36 CP cases with EP were recorded under natural circumstances.Results20 cases (55.6%) had focal high amplitude spikes and wave complexes; 4 cases (11.1%) had typical hypsarrhythmia; 3 cases (8.3%) had varied hypsarrhythmia. Among them, the spikes and wave complexes of 9 cases were bilateral.ConclusionThe most of the clinical attack and EEG characters of CP children with EP are partial type.

Objective To evaluate the relationship of intraerythrocytic calcium(Ca~(2+)),serum cardiac troponin I(cTnI) and contractile and diastolic dysfunction in infants with pneumonia complicated with heart failure(HF),and discuss the role of Ca~(2+) and cTnI.(Met)-hods One hundred and thirty-three infants with pneumonia complicated with HF and 30 healthy children were studied.Intraerythrocytic calcium,serum cTnI and ejection fraction(EF),fractional shortening(FS) and E/A were measured by color Doppler ultrasoundraphy.Results Intraerythrocytic calcium,serum cTnI and EF,FS and E/A in two groups had difference.With the disease deteriorating,the values of Ca~(2+) and cTnI increased,and EF,FS,E/A decreased gradually.There were negative relations between Ca~(2+),cTnI and EF,FS,E/A.Conclusions Ca~(2+),cTnI are concerned with the development of HF.In clinical experiments,the contractile function and diastolic function of heart can be judged by the levels of intraerythrocytic calcium and serum cTnI.

During the treatment of non-small cell lung cancer ( NSCLC) , many patients have developed drug resistance due to the use of targeted EGFR inhibitors. The main reasons for drug resistance are EGFR site mutations and bypass activation. Activation of ALK pathway is one of the major types of bypass activation. A recent authoritative study indicates that ALK is closely related to immunotherapy. This article reviews the treatment of ALK in tumors from three aspects: the structure and physiological function of ALK, the small molecule inhibitor of ALK, the biological function of ALK and its related treatment methods for NSCLC, and prospects future directions for better application of ALK in the treatment of NSCLC.

Objective: To evaluate the diagnostic efficacies of BRAF^V600E testing and Bethesda system for reporting thyroid cytopathology (BSRTC) in thyroid nodules with thyroid imaging reporting and data system (TIRADS) category 4 and 5. Methods: A total of 187 thyroid nodules in 187 patients underwent the examinations of ultrasound-guided fine needle aspiration cytology (FNAC) and BRAF^V600E mutation were analyzed retrospectively. Receive operating characteristic (ROC) curve was used to investigate the diagnostic values of both methods and the clinical application of BRAF^V600E combined with BSRTC was evaluated. SPSS17.0 software was used to analyze the data. Results: Among 187 thyroid nodules, 123 were malignant nodules confirmed with histopathological examination and 64 benign nodules determined by FNAC, histopathological examination, or long-term follow-up. The sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of BRAF^V600E test were better than those of BSRTC [69.1%, 98.4%, 98.8%, 62.4%(χ²=77.3, P=0.000) vs 62.6%, 93.8%, 95.1%, 56.6%(χ²=54.4, P=0.000)]. While the sensitivity, specificity, PPV and NPV of the combined test of BRAF^V600E and BSRTC for diagnosis of malignant thyroid nodules were 87.8%, 92.2%, 95.6%, 79.7%(χ²=112.6, P=0.000), respectively. The area under the ROC curve for the combined test was higher than that for each of tests (0.900 vs 0.858 or 0.838). Conclusions The combined test of BRAF^V600E mutation and BSRTC has a higher diagnostic efficacy for malignant thyroid nodules compared with BRAF^V600E mutation or BSRTC alone.

OBJECTIVETo examine the chemopreventive effect of selective cyclooxygenase-2 (COX-2) inhibitor celecoxib for Barrett's esophagus in rats.

METHODSFifty 8-week-old male Sprague Dawley rats underwent esophagojejunostomy to induce Barrett's esophagus model. Four weeks after operation the animals were given celecoxib 10 mg/(kg*d(-1))(celecoxib group), or saline 1 ml (control group). Another 10 rats were sham operation group. All animals were sacrificed at 20 week after surgery. The degree of inflammation, Barrett's esophagus, adenocarcinoma, COX-2 expression and PGE(2) of animals were assessed.

RESULTAmong 60 rats, 6 rats died in celecoxib group, 8 rats died in control group, 1 rat died in sham operation group, and 45 (75%) rats completed the study. The incidence of mild, moderate and severe degree esophageal inflammation in celecoxib group and control group was 14/19(73.68%), 4/19(21.05%), 1/19(5.26%); 4/17(23.53%), 5/17(29.41%), 8/17(47.06%)(P<0.05), respectively. The incidence of Barrett's esophagus was 7/19(36.84%), 13/17(76.47%) in two group respectively(P<0.05); The incidence of Barrett's esophagus with dysplasia was 2/19(10.53%), 8/17(47.06%)(P<0.05), respectively. The expression of COX-2 was 1/7(14.29%), 10/13(76.92%)(P<0.05) in two groups. PGE2 content was significantly lower in the celecoxib group than that in control group(P<0.001). No esophageal pathological changes were found in sham operation group.

CONCLUSIONSelective COX-2 inhibitors celecoxib can inhibit inflammations, development of Barrett's esophagus and esophagus adenocarcinoma.

OBJECTIVETo establish animal models of reflux esophagitis in rats.

METHODSSeventy male Sprague Dawley rats aged 8 weeks were randomly divided into 4 groups: in Group A (n=20) esophagojejunostomy was performed to induce a gastro-jejuno-esophageal reflux; in Group B (n=20) esophagoduodenostomy was performed to induce a gastro-duodeno-esophageal reflux; in Group C (n=20) total gastrectomy plus esophagojejunostomy was performed to induce a jejuno-esophageal reflux; in Group D (n=10) only was performed sham operation (control).

RESULTAmong 70 rats, 6 died in Group A, 7 died in Group B, 6 died in Group C, and 72.9 %(51/70) animals were completed in the study. After 12 weeks the incidence of esophageal inflammation was 100.0%; in Groups A, B and C erosion occurred in 11/14 (78.6%), 10/13 (76.9%), 3/14 (21.4%) of animals, respectively; squamous dysplasia was in 10/14 (71.4%), 10/13 (76.9%), 5/14 (35.7%) of rats, respectively; Barrett's esophagus was in 6/14 (42.9%), 5/13 (38.5%), 1/14 (7.1%), respectively. One esophageal adenocarcinoma was found in Group A; no histological changes were observed in Group D.

CONCLUSIONThe animal models of reflux esophagitis can be induced by esophagojejunostomy, esophagoduodenostomy or total gastrectomy plus esophago-jejunostomy in rats; and the former two surgical modalities are better than the later.

OBJECTIVEOvarian fibrosis is characterized by excessive proliferation of ovarian fibroblasts and deposition of extracellular matrix (ECM) and it is one of the principal reasons for ovarian dysfunction. This review aimed to investigate the pathogenetic mechanism of ovarian fibrosis and to clarify the relationship between ovarian diseases and fibrosis.

DATA SOURCESWe searched PubMed for English language articles published up to November 2016. The search terms included ovarian fibrosis OR fibrosis, ovarian chocolate cyst OR ovarian endometrioma, polycystic ovarian syndrome (PCOS), premature ovarian failure, ECM, matrix metalloproteinases (MMPs), tissue inhibitors of matrix metalloproteinases (TIMPs), transforming growth factor-beta 1 (TGF-β1), connective tissue growth factor (CTGF), peroxisome proliferator-activated receptor gamma (PPAR-γ), vascular endothelial growth factor (VEGF), endothelin-1 (ET-1), and combinations of these terms.

STUDY SELECTIONArticles were obtained and reviewed to analyze the pathogenic mechanism of ovarian fibrosis and related ovarian diseases.

RESULTSMany cytokines, such as MMPs, TIMPs, TGF-β1, CTGF, PPAR-γ, VEGF, and ET-1, are involved in ovarian fibrogenesis. Ovarian fibrogenesis is associated with various ovarian diseases, including ovarian chocolate cyst, PCOS, and premature ovarian failure. One finding of particular interest is that fibrogenesis in peripheral tissues around an ovarian chocolate cyst commonly causes ovarian function diminution, and therefore, this medical problem should arouse widespread concern in clinicians worldwide.

CONCLUSIONSPatients with ovarian fibrosis are susceptible to infertility and tend to have decreased responses to assisted fertility treatment. Thus, protection of ovarian function should be a priority for women who wish to reproduce when making therapeutic decisions about ovarian fibrosis-related diseases.
