Objective:To evaluate the diagnostic value of 18G and 16G needle biopsy of breast lesions.Methods: Onr hundred and fifteen patients with breast lesions those were excised through surgery. Each lesion was under ultrasound-guided needle biopsy(US-CNB) with 18G and 16G, then underwent surgical resection of mass and pathological histology. Histological findings of US-CNB and the surgical specimens were analyzed for sensitivities, false negative rates, and underestimate rates.Results: Among 84 cases of breast cancer proved by surgical pathology, the sensitivity, specificity, false negative rate of 18G and 16G biopsy diagnosis were followed by 95.2% and 97.6%, 89.6% and 94.3%, 4.8% and 2.4%. Paired chi-square test showed no significant difference between the two methods.Conclusion: 18G and 16G needle biopsy has no significant difference in the diagnosis of breast lesions.

Objective To investigate the distribution pattern of the ADAS-Cog scores among the elderly in Beijing and to evaluate the application of ADAS-Cog in distinguishing patients with mild Alzheimer's disease (AD) and healthy elderly. Methods In total, 1616 healthy elderly (NC), 125 elderly patients with non-AD disorders (ND), and 310 patients with probable AD including 201 patients with mild AD and 109 patients with moderate AD (by NINCDS-ADRDA criteria) were recruited in the study and their cognitive performance was measured by the ADAS-Cog.Results In NC group, those older than 80 years and those with less than 5 years schooling scored highest. There was statistically significant correlation between the total scores of the ADAS-Cog and age and duration of schooling in NC group (F=14.34, 113.27,both P<0.01). No correlation was suggested in the mild AD group. The total score of ADAS-Cog was significantly associated with duration of schooling in both moderate AD and ND groups (F=4.18, 8.72, both P<0.05). The total score of ADAS-Cog differentiated the patients with mild AD from NC healthy elderly with AUC ranging from 0.69 to 0.82 in each subgroup by age, and from 0.75 to 0.88 in subgroups by durations of schooling with the highest AUC of 0.88 in the subgroup having more than 15 years of schooling education. Conclusions The ADAS-Cog score in the healthy elderly is significantly associated with age and duration of schooling education. The ADAS-Cog can be applied in the cognitive assessment of Chinese AD patients. The total score of ADAS-Cog could efficiently differentiate patients with mild AD from healthy elderly, especially in subjects with higher education level.

Background Measurement of corneal thickness is important for the early diagnosis and treatment of some eye disorders,including corneal diseases and refractive errors.However,the corneal parameters from schoolage population are rarely reported.Objective The aim of this survey was to characterize the central corneal thickness (CCT),minimum corneal thickness (MCT) and paracentral corneal thickness in healthy Chinese schoolage population.Methods A cross-sectional study was designed in this study.Children aged 7 to 15 years with the diopter of-3.00 D to +3.00 D were recruited from two primary schools in Baoshan district in Shanghai based on random cluster sampling under the approval of Shanghai First People's Hospital and informed consent of child custodian.Routine examinations were firstly performed to determine the healthy participants.CCT (within 2 mm range away the corneal vertex),MCT and paracentral corneal thicknesses (2 to 5 mm zone away the cornea vertex in superior,inferior,nasal and temporal quadrants) were then measured by RTVue Fourier optical coherence tomography (OCT) for the comparison between both eyes and different gender.The subjects were grouped into the 7-9,10-12 and 13-15 years groups,and the correlations between age and CCT,MCT and paracental corneal thicknesses were analyzed.The coordinate position of the thinnest cornea was determined.Results A total of 147 children were enrolled in the study.The mean CCT value of the right eyes was (537.77±29.33) μm,and that of the left eyes was (539.22±29.16) μm,showing a significant difference between them (t =-3.21,P =0.00).The paracentral corneal thicknesses of the right and left eyes were (565.52±30.11) μm and (568.42±31.07) pm in the superior quadrant,and those in the temporal quadrant were (549.01 ±30.46) μm and (547.24±30.23) μm,with significant differences between them (t =-2.47,P =0.01 ; t =2.12,P =0.04).No significant difference was found in the CCT,MCT,paracentral corneal thicknesses from various quadrants (all at P＞0.05).In addition,no considerably correlation was seen between age and CCT,MCT and paracentral corneal thickness (all at P＞0.05).The thinnest cornea area was located in the inferotemporal region in 40.82％ right eyes and 57.82％ left eyes.The distance of thinnest cornea area away corneal vertex was (0.62±0.33)mm in the right eyes and (0.91±0.63)mm in the left eyes,with a significant difference between them (t =-5.17,P =0.00).Conclusions The central,superior and temporal corneal thicknesses are significantly different between the right and the left eyes among healthy Chinese school-age children,but corneal thickness change is not associated with age or gender.The thinnest corneal area does not locate at the vertex.

Objective To study the effects of recombinant human growth hormone(rhGH) on the treatment for valve replacement postoperative in rheumatic heart disease associated cardiac eaehex.Methods Fortytwo patients with rheumatic heart disease associated cardiac eachexia were divided into two groups.Group one(n=20,rhGH group) received standard enteral nutrition (15 kal·kg-1 · d-1)with rhGH 10U injection subeutaneously from postoperation day 7 to day 14 and group two(n = 22,eontrol group) received standard enteral nutrition (15 kal·kg-1· d-1) for the same period.Haemoglobin, serum total protein, serum albumin, blood glucose, handgrip exercise and triceps skin_fold thickness were determined.Meehanieal ventilation, hypostatie pneumonia incidence rate, and length of stay were observed.Results The levels of serum total protein, serum albumin and blood glucose eoneentration in the rhGH group at the 14th day were inereased significantly compared to that in the control group(P <0.01).Haemoglobin, triceps skinfold thiekness and handgrip exercise in rhGH group were significantly different from those in the control group(P <0.05).Postoperative meehanieal ventilation time, intensive care unit time, hospital stay time were signifieantly shorter than those in the eontrol group (P < 0.05), and hypostatie pneumonia was significantly lower than that in the eontroi group(P < 0.01).Conclusions The rhGH can obviously improve anabolie effects of patients with rheumatic heart disease associated cardiac eachexia whieh can reduce hypostatie pneumonia and shorten postoperative hospital stay time.

Objective To analyze and summarize the skills and complications of extracorporeal membrane oxygenation( ECMO) cannu-lation and vein intubation. Methods The clinical data of 21 patients of V-A or V-V ECMO in our hospital from January 2009 to July 2014 were analyzed retrospectively. And the techniques of different catheter sites were summarized. Results Three cases were successfully insert-ed catheter by jugular vein puncture with one time.

Background Epidemiologieal survey suggests that visual impairment in teenagers is a worldwide public health problem,and its leading cause is uncorrected refractive error.To conduct an extensive screening of visual impairment in teenagers and analyze the relevant affecting factors are significant works for the prevention and management of refractive errors.But high-quality epidemiological data on visual impairment and refractive error from large groups of children are lacking in Shanghai.Objective This study was to investigate the prevalence of ametropia and visual impairment in schoolchildren aged 6 to 12 years old.Methods In this cross-sectional study,4 686 students from 6 elementary schools in Baoshan District of Shanghai,a rural-urban fringe zone,China were selected by clustering sampling from May 2010 to April 2011.The eye examinations included visual acuity,ocular surface,ocular anterior segment,ocular media,fundus and intraocular pressure measurement,and the data autorefraction under cycloplegia and eye position were recorded.The cause of visual impairment was evaluated.Results A total of 4 594 students received examination with the response rate 98.0％,and autorefraction under cycloplegia was completed in 84.8％ schoolchildren (3 975/4 594).The prevalence rate of uncorrected visual acuity 0.5 or worse in both eyes was 14.4％ (662/4 594),with the wearing glasses rate 51.8％ (343/662).The percentage of students with the uncorrected visual acuity 0.5 or worse in at least one eye was 22.4％ (1 031/4 594).The prevalence rate of refractive error in the visual impaired students was 96.9％ (999/1 031),followed by amblyopia (37/1 031,3.6％).The prevalence rate of myopia,hyperopia,and astigmatic in the pupils after cycloplegia was 31.1％,4.3 ％ and 33.0％,respectively.In addition,the prevalence rate of myopia in public elementary schools was higher than that in migrant elementary schools (33.9％ versus 30.3％) (x2 =5.46,P =0.02).Logistic regression analysis showed that myopia was associated with age (OR =1.60,95 ％ CI:1.53-1.68,P ＜ 0.01) and female (OR =1.33,95％ CI:1.16-1.54,P＜0.01).Conclusions The leading cause of vision impairment is myopia in the elementary school students in Shanghai,China.The screening-ratio of refractive error and the coverage of refractive correction in the elementary school students in Shanghai are matters of urgent concern.

Objective To improve the awareness of fetal cardiac rhabdomyomas (CRs) and investigate a better model for prenatal diagnosis and treatment through analyzing imaging findings and prognosis.Methods A retrospective study was conducted on 23 cases of CRs which were diagnosed by ultrasound in Obstetrics and Gynecology Hospital of Fudan University from January 2008 to November 2015.General conditions,imaging features,prognosis and follow-up data of the 23 cases were described.Results The average gestational age of the 23 fetuses at diagnosis was (29.8±4.1) (22.4-35.7) weeks.Seventeen out of the 23 gravidas received prenatal multidisciplinary consultation.Among all 23 gravidas,three (13％) were lost to follow-up,12 (52％) decided to terminate the pregnancy,and the other eight (35％) continued to term pregnancy and their babies were followed up for three years.Of these eight cases,two cases received prenatal brain MRI and no tuberous sclerosis complex (TSC) was detected,no CRs was identified during the follow-up,and their physical and mental developments were both normal.One case was diagnosed with suspected subependymal nodules by prenatal brain MRI in our hospital,but the MRI images was normal when scanned in the other hospital,and follow-up data revealed neither CRs nor abnormal physical and mental developments.Four cases did not received prenatal brain MRI,but the MRI images of neonatal brains indicated TSC,besides,follow-up data showed that seizures were observed,physical developments were all normal,but three of the four cases had mental retardation;CRs disappeared in only two of the four cases.One case had neither prenatal nor neonatal MRI,but follow-up data showed that CRs had disappeared and physical and mental developments were both normal.Conclusions Prenatal diagnosis of fetal tuberous sclerosis is crucial to the prognosis of CRs.Prenatal ultrasonography in combination with cranial MRI improves the accuracy of prenatal diagnosis of CRs complicated with TSC and assists in clinical decision-making and prognosis analysis.

Objective To explore the associations between coagulation factor Ⅶ (FⅦ)polymorphisms and its haplotype with risk of ischemic cerebrovascular diseases (ICVD) in Henan Han population. Methods Five hundred and twelve cases with ICVD as patient group and 560 healthy subjects as control were recruited in the study. The polymorphisms of R353Q, 5'F7 and IVS7 were detected by PCR-RFLP. The genotype frequency and allele gene frequency were compared between ICVD group and control group. The haplotype was analyzed by SHEsis software. Results The RQ genotype frequencies and Q allele frequencies of ICVD group were significantly lower than those of control group. The distribution of H7 allele frequencies and H6H7 genotype frequencies of FⅦ/IVS7 polymorphisms had significant difference between ICVD group and control group. Finally, the prevalence of R-P0-H6 haplotype in ICVD group(53. 3% )was higher than that in control group (47.5%, OR = 1. 219, 95% CI 1. 028-1. 446,P =0.023). Conclusions In Henan Han population, the Q allele of F Ⅶ/R353Q polymorphisms and the H7 allele of F Ⅶ/IVS7 polymorphisms may be protective genetic factors against ischemic cerebrovascular disease, and the R-P0-H6 haplotype may be a risk factor of ischemic cerebrovascular disease.
