Objective To study the appropriate neck irradiation volume for neck lymph nodenegative nasopharyngeal carcinoma patients by Meta-analysis.Methods The related references published from Jan 1990 to Jun 2013 were searched in Pubmed,Embase,Cochrane and Wangfang Databases.The qualified references for enrollment criteria were screened and the relative data were collected.The OR (Odds ratio) value by fixed effect model was used to evaluate the data for patients who received radiotherapy between the upper neck and whole neck irradiation.The endpoints including 5-year neck local control rate (LCR),neck-in-irradiation LCR,and neck-outsides-irradiation LCR.Results Five qualified references were screened and belonged to respective research.There enrolled 1 333 patients,including 970 patients who received the upper neck irradiation and 363 patients who received the whole neck irradiation,respectively.The forest plots revealed that there were no significant differences for 5-year neck LCR,neckin-irradiation LCR,and neck-outsides-irradiation LCR for patients received radiotherapy between the upper neck and whole neck irradiation.These OR values were 0.89 (95％ CI:0.41-1.94),1.29 (95％ CI:0.58-2.88) and 0.42 (95％ CI:0.07-2.36),respectively.Conclusions The Meta-analysis results suggest that irradiation to the upper neck for neck lymph node-negative nasopharyngeal carcinoma can be appropriate.

The means of survival of genomic dsRNA of reoviruses from dsRNA-triggered and Dicer-initiated RNAi pathway remains to be defined.The present study aimed to investigate the effect of Grass carp reovirus (GCRV) replication on the RNAi pathway of grass carp kidney cells (CIK).The dsRNA-triggered RNAi pathway was demonstrated unimpaired in CIK cells through RNAi assay.GCRV-specific siRNA was generated in CIK cells transfected with purified GCRV genomic dsRNA in Northern blot analysis; while in GCRV-infected CIK cells,no GCRV-specific siRNA could be detected.Infection and transfection experiments further indicated that replication of GCRV correlated with the increased transcription level of the Dicer gene and functional inhibition of in vitro synthesized egfp-siRNA in silencing the EGFP reporter gene.These data demonstrated that although only the genomic dsRNA of GCRV was sensitive to the cellular RNAi pathway,unidentified RNAi suppressor protein(s) might contribute to the survival of the viral genome and efficient viral replication.

Objective To summarize the clinical characteristics of neonates with non-immune hydrops fetalis.Methods The clinical data of ten neonates with non-immune hydrops fetalis, who were admitted to the Department of Neonatology, Gynecology and Obstetrics Hospital of Fudan University between January 2012 and June 2014, were retrospectively studied.Prenatal characteristics, causes, clinical features and prognosis were explored and analyzed with descriptive statistical methods.Results (1) One of the ten neonates was diagnosed after birth presented with hydroderma and abdominal distension, and the rest ones were diagnosed antenatally.There were six males and four females, and eight premature and two term neonates with the average gestational age of (33.6±2.4) weeks and birth weight of(2 680±478) g.(2) The mean maternal age was (30.3 ±4.6) years.Two of the mothers had gestational diabetes mellitus and one had gestational diabetes mellitus complicating with hyperthyroidism.The blood types of all mothers were O and Rh(+).None of the mothers were tested for parvovirus B19 and no fetus was reported with abnormal chromosome karyotype in the five cases received fetal karyotype analysis.(3) The average gestational age at initial identification of hydrops fetalis by fetal ultrasound was (31.3 ± 2.4) weeks (25.1～37.0 weeks) among nine cases diagnosed prenatally.By ultrasound screening, there were seven cases with hydrothorax, six with seroperitoneum, five with polyhydramnios and four with hydroderm.(4) Two neonates had normal non-stress test results during labor, and eight were abnormal and suffered from severe neonatal asphyxia at birth and resuscitated by endotracheal intubation.Ten neonates had hydroderm, seven had hydrothorax, six had seroperitoneum and one had hydropericardium.One complicated with multiple malformations and one had chromosome abnormality.Four cases received thoracentesis and three had abdominal paracentesis after parturition.(5) Prognosis: One neonate survived and nine died among which six due to resuscitation failure in delivery room, two died one day after giving up treatment after one day, and one died due to treatment failure six months after birth.(6) The causes of hydrops fetalis were anemia (two cases) and congenital diaphragmatic hemangioma, recurrent atrial premature beat, Down's syndrome, congenital pulmonary lymphangiectasia, paroxysmal supraventricular tachycardia, placental chorioangioma, suspicious genetic syndrome and idiopathic (one for each).Conclusions The prognosis varies because of different etiology of non-immune hydrops fetalis.Neonates with hydrops fetalis might have a higher rate of asphyxia and mortality rate, and difficulties in resuscitation at birth.

Objective: To evaluate the diagnostic performance of conventional ultrasound, compression elastography (CE) and acoustic radiation force impulse imaging (ARFI) in diff erential diagnosis of benign and malignant breast tumors. Methods: A total of 98 patients with liver lesions were included in the study. The images of conventional ultrasound, CE and the values of virtual touch tissue quantiifcation (VTQ) of breast lesions were obtained. hTe diagnostic performance of conventional ultrasound, CE and ARFI were assessed by using pathology as the gold standard, and then evaluate the diagnosis effciency of these three approaches in differential diagnosing benign and malignant breast tumors. Results: The specificity, sensitivity and accuracy in the diagnosis of malignant breast tumors for conventional ultrasound were 80.0%, 81.1% and 81.7%, respectively, whereas for CE elastic score were 85.7%, 86.7% and 86.3%, respectively. With a cutoff value of 3.71 for the SR, the sensitivity, speciifcity, accuracy in diagnosis of malignant breast tumors were 97.1%, 83.3% and 88.4%, respectively. With a cutoff value of 3.78 m/s for VTQ, the sensitivity, speciifcity, accuracy in diagnosis of malignant breast tumors were 94.3%, 91.7% and 92.6%, respectively. The difference in diagnosis efficiency among ARFI, CE and conventional ultrasound in differential diagnosis of benign and malignant breast tumors was signiifcant (P<0.05). Conclusion: Conventional ultrasound, CE and ARFI are all useful for the differential diagnosis of benign and malignant breast tumors. But the diagnosis effciency of ARFI is superior to CE and conventional ultrasound. The three approaches can help each other in differential diagnosis of benign and malignant breast tumors.

Objective To evaluate the ultrasonic feature and clinical significance of persistent left superior vena cava(PLSVC)in fetal life.Methods Fetal echocardiography was performed in 3368 fetuses.Thirty-one fetuses of PLSVC were confirmed.Results The dilated coronary sinus was observed in 30 of 31 fetuses.Congenital heart defects were presented in 14 of these cases,and extracardiac anomalies were presented in 6 fetuses.Both congenital heart defects and extracardiac anomalies were observed in 4 fetuses.Conclusions PLSVC is always associated with congenital heart defects.The prognosis Of affected fetuses largely depends on whether or not the PLSVC is associated with a congenital heart defect.Prenatal diagnosis of PLSVC can help US plan perinatal counseling and ameliorate the postnatal course.

Cold atmospheric plasma (CAP), a redox modulation tool, is capable of inhibiting a wide spectrum of cancers and has thus been proposed as an emerging onco-therapy. However, with incremental successes consecutively reported on the anticancer efficacy of CAP, no consensus has been made on the types of tumours sensitive to CAP due to the different intrinsic characteristics of the cells and the heterogeneous design of CAP devices and their parameter configurations. These factors have substantially hindered the clinical use of CAP as an oncotherapy. It is thus imperative to clarify the tumour types responsive to CAP, the experimental models available for CAP-associated investigations, CAP administration strategies and the mechanisms by which CAP exerts its anticancer effects with the aim of identifying important yet less studied areas to accelerate the process of translating CAP into clinical use and fostering the field of plasma oncology.

Objective: To assess the outcomes and toxic effects of 5-day actinomycin D (Act-D) salvage therapy and to explore the predictors of Act-D resistance in patients with low-risk gestational trophoblastic neoplasia (GTN)who failed 5-day methotrexate (MTX) chemotherapy. Methods: This retrospective study analyzed patients with low-risk GTN administered Act-D salvage therapy after failing MTX chemotherapy at Women's Hospital, School of Medicine Zhejiang University between January 2000 and December 2015. The clinical parameters of these patients were collected and analyzed. Results: The final analysis included 89 cases. Of these, 73 cases (82.02%) responded to salvage Act-D. The remaining 16 resistant cases were switched to etoposide, MTX, Act-D/ cyclophosphamide, and vincristine chemotherapy and achieved complete remission. Serum human chorionic gonadotrophin levels before Act-D salvage therapy (hCG Act-D )in the Act-Dresistant cases were significantly higher than those in the Act-D responders (median 605 vs.103 IU/L, p=0.009). However, the range of hCGAct-D values in Act-D responders was wider than that in Act-D-resistant cases (5.76–16,664 IU/L vs. 11.43–6,732 IU/L). Thus, assigning a general cut-off value was difficult considering the individual setting. Except for 2 cases requiring other salvage regimens due to Act-D toxicity, 97.80% of cases (89/91) tolerated the toxicity. During at least 1-year follow-up, the survival rate was 100.00% and no case developed recurrence. Conclusion Based on the good therapeutic effect and tolerable toxicity, we recommend Act-D salvage therapy for all patients with low-risk GTN who fail primary MTX chemotherapy.The higher serum hCG levels before Act-D salvage therapy may be associated with resistance to this treatment.

To fulfill the calibration requirements for absorbed dose to water in external beam radiotherapy,the summary offers a streamlined calibration procedure and recommendations in accordance with TRS-398(version 7)published by International Atomic Energy Agency in 2024.It addresses various considerations for reference measurement conditions in external beam radiotherapy and defines the appropriate scope for ionization chambers.In terms of ionization chamber measurements,it elaborates on the methods for measuring various correction factors and provides a table of beam quality conversion factors.The calibration uncertainty is examined by comparing the contributions of different factors before and after the update.The results demonstrate that using IBA FC65-G ionization chamber to calibrate high-energy photon beams,high-energy electron beams,proton beams and light ion beams results in relative deviations of-0.4％,0.5％,-1.7％and-1.3％as compared with the earlier versions,with relative standard uncertainties of 1.0％,1.1％,1.7％and 2.6％,respectively.The guideline which is tailored to the national radiotherapy dose calibration standards and practices presents an optimized calibration approach for TRS-398,allowing clinicians to conduct absolute dose calibration more efficiently and accurately.

Healthy lifestyles and good living habits are effective strategies and important approaches to prevent chronic non-communicable diseases. With the development of evidence-based medicine, the evidence translation system has made some achievements in clinical practice. There is, however, no comprehensive, professional and efficient system for translating lifestyle evidence globally. Therefore, the Health Lifestyle Evidence (HLSE) Group of Lanzhou University constructed the HLSE Evidence Translation System (https://hlse.cn/), with the aim of synthesizing, evaluating, translating, and applying lifestyle-related evidence resources. This paper aims to introduce the functional module design of the evidence translation system, the system development process and testing, introduce the interface design and function demonstration, and explain the significance of constructing the HLSE.
