ObjectiveTo summarize the ultrasonic features of endometrial carcinoma in transvaginal color Doppler sonography (TVCDS), and to analyze the supplementary function of serum CA125and CA199in diagnosing endometrial carcinoma.MethodsFrom January 2006 to October 2012, fourteen thousand and twenty-seven women underwent TVCDS in GZ Women & Children Medical Centre, serum CA125 and CA199 were determined by chemiluminescence immunoassay. The ultrasound characteristics of 131 cases of endometrial carcinoma (including 64 cases of early-stage and 67 cases of advanced endometrial carcinoma) who were accurately diagnosed by pathology and the value of serum CA125 and CA199 were analyzed.ResultsIn groups 131 patients were accurately conifrmed by pathology, including 64 cases early-stage and 67 cases advanced carcinoma. The diagnositic coincidence of ultrasound and ultrasound combined with serum tumor markers was 56.3% (36/64) and 78.1% (50/64) respectively. On ultrasonography, 64 patients with early stage endometrial carcinoma showed uterine enlargement in 38 cases and endometrial thickening in 53 cases. In 9 cases, endometrial lesions were heterogeneously hypoechoic. In 55 cases, the halo between endometrium and muscle was interrupted and disappeared. In 56 cases, endometrial lesions had muscular layer inifltration. In 13 cases, endometrial lesions had cervical inifltration. In 61 cases, sparse punctuate or reticular flow signals were detected within lesions. In 3 cases, there was no blood flow signal in lesions. All these patients had not lymph node metastasis. Sixty-seven cases with advanced endometrial carcinoma showed more obviously uterine enlargement and significant endometrial thickening. In 61 patients, tumor spread outside the uterus. Reticular or dendritic flow signals were detected in 67 cases lesions. There were hypoechoic lymph node mestastasis in 53 cases. In 31 cases of early stage endometrial carcinoma, preoperative CA125 increased. In 27 cases of early stage endometrial carcinoma, preoperative CA199 increased. In 24 cases CA125 and CA199 increased meanwhile. In 61 cases of advanced endometrial carcinoma, preoperative CA125 increased. In 59 cases of advanced endometrial carcinoma, preoperative CA199 increased. In 56 cases CA125 and CA199 increased meanwhile. Sixty-four cases of early-stage endometrial carcinoma were diagnosed by TVCDS assisted with CA125 and CA199 and were confirmed by pathology. The detective rate was 78.1% (50/64). To compared with TVCDS, the difference was statistical signiifcance (χ2=6.95,P=0.01).ConclusionsThe ultrasonic features of early-stage endometrial carcinoma in TVCDS were uterine enlargement, endometrial thickening, heterogeneous hypoechoic endometrial lesions, interrupted or disappeared hypoechoic halo between endometrium and musclar layer, and sparse punctuate or reticular flow signals within lesions. Serum CA125 and CA199 may be helpful in improving diagnosis coincidence rate when early-stage endometrial cancer is ifnd or suspected on ultrasonography.

Objective To study the risk factors for children with acute central nervous system(CNS)viral in-fection,so that pediatrician may identify children with poor prognosis at early stages of the disease,and provide them with a theoretical basis for clinical treatment. Methods The clinical data of a cohort patients of acute CNS viral infec-tion who were hospitalized at the First Affiliated Hospital of Fujian Medical University between January 2010 and June 2013 were retrospectively collected and analyzed. According to Glasgow outcome scale on discharge,children were di-vided into good prognosis group and poor prognosis group. Clinical data and outcomes were analyzed by using univariate analysis and binary Logistic regression multivariate analysis. Results Three hundred and one cases were enrolled,278 (92. 36% )patients were assigned to the good prognosis group,and 23(7. 64% )patients were assigned to the poor prognosis group. By univariate analysis,the patients in the poor prognosis group had longer duration of sickness before admission,longer time of fever,lower white blood cell count in cerebrospinal fluid,a relatively lower calcium level,con-scious disturbance at the early stage,multiple seizures,convulsive status epilepticus,meningeal irritation sign,muscle weakness,severe changes in electroencephalogram(EEG),and abnormal neuroimaging findings(computed tomography or magnetic resonance imaging,or both)had significant differences between the good prognosis group and the poor short - term outcome groups(all P < 0. 05). By binary Logistic regression multivariate analysis,factors indicating a poor prognosis during the early stage were conscious disturbance at the early stage(0R = 4. 885,95% CI:1. 523 - 15. 670, P = 0. 008),multiple seizures(0R = 6. 352,95% CI:1. 905 - 21. 178,P = 0. 003),severe changes in EEG( 0R =4. 269,95% CI:1. 708 - 10. 666,P = 0. 002),and abnormal neuroimaging findings( 0R = 9. 740,95% CI:2. 360 -40. 192,P = 0. 002). Conclusions Conscious disturbance at the early stage,multiple seizures,severe changes in EEG and abnormal neuroimaging findings are risk factors for acute viral infection of CNS in children.

Decreasing complication rate, favorable social benefit and approval of the patients family members will be seen due to involvement of the patients family in health education.

Objective:To establish a method based on the iPLEX analysis of MassARRAY mass spectrometry platform to detect multiplex genetic mutations among Chinese lung cancer patients. Methods:We reviewed the related literature and data of lung cancer treatments. We also determined 99 mutation hot spots in 13 target genes, namely, EGFR, KRAS, ALK, FGFR1, FGFR2, FGFR3, PIK3CA, BRAF, PTEN, MET, ERBB2, AKT1, and STK11, which are closely related to the pathogenesis, drug resistance, and metastasis of lung cancer and are associated with relevant transduction pathways. A total of 297 primers comprising 99 paired forward and reverse amplification primers and 99 matched extension primers were designed by using Assay Design in accordance with the mutation label and format requirements of the MassARRAY platform. The detection method was established by analyzing eight cell lines and six lung cancer specimens;the proposed method was then validated through comparisons with a LungCarta kit. The sensitivity and specificity of the proposed method were evaluated by directly sequencing EGFR and KRAS genes in 100 lung cancer cases. Results:The proposed method could detect multiplex genetic mutations in the lung cancer cell lines, and this finding is consistent with that observed using previously reported methods. The proposed method could also detect such mutations in clinical lung cancer specimens;this result is also consistent with that observed by using the LungCarta kit. However, an FGFR2 mutation was detected only by using the proposed method. The measured sensitivity and specificity were 100%and 96.3%, respectively. Conclusion:The proposed MassARRAY technology-based method could detect multiplex genetic mutations among Chinese lung cancer patients. Indeed, the proposed method can be potentially applied to detect mutations in cancer cells.

OBJECTIVE: To analyze the clinical phenotype and genetic basis for a male neonate featuring hypoparathyroidism, sensorineural hearing loss, and renal dysplasia (HDR) syndrome. METHODS: The child was subjected to genome-wide copy number variation (CNVs) analysis and whole exome sequencing (WES). Clinical data of the patient was analyzed. A literature review was also carried out. RESULTS: The patient, a male neonate, had presented with peculiar facial appearance, simian crease and sacrococcygeal mass. Blood test revealed hypocalcemia, hypoparathyroidism. Hearing test suggested bilateral sensorineural deafness. Doppler ultrasound showed absence of right kidney. Copy number variation sequencing revealed a 12.71 Mb deletion at 10p15.3-p13 (chr10: 105 001_12 815 001) region. WES confirmed haploinsufficiency of the GATA3 gene. With supplement of calcium and vitamin D, the condition of the child has improved. CONCLUSION The deletion of 10p15.3p13 probably underlay the HDR syndrome in this patient.

Objective To investigate the inhibitory effect of epigallocatechin gallate(EGCG)on oxidative damage to the retina in a rat model of dry age-related macular degeneration(AMD)induced by sodium iodate.Methods A total of 36 male specific pathogen-free Sprague-Dawley rats were randomly divided into the blank control group,sodium iodate group and sodium iodate+EGCG group,with 12 rats in each group.Rats in the sodium iodate group and the sodium io-date+EGCG group were given 50 mg-kg·1 sodium iodate by tail vein injection by weight to build dry AMD models,while rats in the blank control group were administered with an equal volume of normal saline.Following the modeling proce-dure,rats in the sodium iodate+EGCG group received an intravitreal injection of 4 μL EGCG(0.5 g·L-1)into their right eyes,while the right eyes of rats in both the blank control and sodium iodate groups were treated with the same volume of normal saline.After 21 days,the rats were sacrificed,and ocular samples were collected for detection.Histopathological changes of the retinal tissues in each group were examined using hematoxylin and eosin(HE)staining.Additionally,the levels of superoxide dismutase(SOD),glutathione peroxidase(GSH-Px),and malondialdehyde(MDA)in the retinal tis-sues were quantified.Western blot analysis was conducted to assess the protein expression levels of nuclear factor ery-throid-2-related factor 2(Nrf2),NADPH quinone oxidoreductase 1(NQO1),and heme oxygenase-1(HO-1)in the retinas.Furthermore,real-time quantitative polymerase chain reaction was performed to evaluate the relative messenger ribonucleic acid(mRNA)expression levels of Nrf2,NQO1 and HO-1 in the retinas of the rats.Results HE staining revealed that,in comparison to the blank control group,the entire retinal layer in the sodium iodate group exhibited injury,characterized by noticeable injury of the retinal pigment epithelial cells and disordered outer nuclear layer with wavy transformation.The so-dium iodate+EGCG group demonstrated ameliorated retinal injury across all layers compared to the sodium iodate group.Compared to the blank control group,the levels of SOD and GSH-Px were significantly reduced(both P＜0.01),while the level of MDA was significantly elevated(P＜0.01)in the sodium iodate group.Compared with the sodium iodate group,the sodium iodate+EGCG group showed a significant increase in the levels of SOD and GSH-Px(both P＜0.01),along-side a substantial decrease in the content of MDA(P＜0.01).Western blot analyses demonstrated that compared with the blank control group,the protein expression levels of Nrf2,NQO1 and HO-1 were significantly elevated in the sodium iodate group(all P＜0.01);compared with the sodium iodate group,the sodium iodate+EGCG group exhibited relatively higher protein expression levels of Nrf2,NQO1 and HO-1(all P＜0.05).The results from real-time quantitative polymerase chain reaction indicated that the relative mRNA expression levels of Nrf2,NQO1 and HO-1 in the retinas of rats in the sodium io-date group were significantly greater than those in the blank control group(all P＜0.05);compared with the sodium iodate group,the sodium iodate+EGCG group showed a significant increase in the relative mRNA expression levels of Nrf2,NQO1 and HO-1(all P＜0.05).Conclusion EGCG can improve the capacity to scavenge oxygen free radicals by promo-ting the upregulation of Nrf2 expression.This activation subsequently enhances the expression of downstream products such as NQO1 and HO-1,leading to increased levels of SOD and GSH-Px while simultaneously reducing the MDA level.Consequently,this process inhibits oxidative damage to the retina in rats with dry AMD induced by sodium iodate.
