Objective To study the effect of autoantibody test which includes antinuclear antibodies(ANA),antinuclear antibody fluorescence patterns,anti-extractable nuclear antigen(ENA) antibodies and anti-double strands DNA(ds-DNA) antibodies in the diagnosis of pediactic autoimmune diseases.Methods Of all the inpatients which had positive results of autoantibody tests,135 cases were reviewed.The autoantibody assay,positive value(PV) analysis were performed respectively.Results PV of ANA test to autoimmune diseases was 0.36 which was proportional to the intensity of fluorescence;Of all the fluorescence patterns,speckled(fine) had a relatively high PV;Anti-ENA and anti-dsDNA antibody tests had higher PV than ANA test.Conclusion Fluorescence intensity,(anti-ENA) antibody test and anti-dsDNA antibody test may be useful in identifying autoimmune diseases in clinic.

Objective To understand the epidemiological distribution and epidemic situation of brucellosis cases in Zhejiang Province in 2003 - 2012. Methods Questionnaires of confirmed brucellosis cases, annual reports of prevention and control work of brucellosis in the cities and monitoring points were collected and analyzed in 2003 - 2012. Population distribution, regional distribution, infection sources and routes of infection, aetiology and clinical symptoms and signs of the brucellosis cases were analyzed descriptively. Results A total of 323 brucellosis cases were reported in 2003 - 2012, the average annual incidence rate was 0.070/one hundred thousand, the incidence rate in 2012(0.190/one hundred thousand) was high. There were 272 people of the 323 brucellosis cases were from occupational populations, accounting for 84.21%(272/323); people worked in buying, slaughtering and trafficking of livestock products were majority of the cases, accounting for 65.02%(210/323); and unoccupational population was accounting for 15.79%(51/323). Regional distribution of brucellosis was gradually spreading; the average incidence rate of Shaoxing City was the highest ( 0 . 226/one hundred thousand ) . Three hundred patients were infected by sheep, accounting for 92.88%(300/323), and only 7.12%(23/323) of the patients were infected by cattle. Two hundred and eighty-seven acute phase patients of brucellosis were checked by blood culture, and thirty-nine Brucella melitensis strains and two Brucella abortus strains were detected. The chronicity survey of 120 confirmed cases of brucellosis were conducted, chronicity rate was 3.33%(4/120). Conclusions Trends in the epidemic situation of brucellosis in Zhejiang Province has continued to spread. The main source of infection is sheep from the North. Occupational populations are major populations at risk. The key of prevention and control is to strengthen the active monitoring of occupation personnel , health education and behavior intervention.

Nowadays the role of genetic findings in determining the diagnosis, therapy and prognosis of acute myeloid leukemia (AML) has become more valuable. To improve and validate the detection of clonal chromosomal aberrations in leukemia, we designed a combined application of karyotyping with multiplex reverse transcription-polymerase chain reaction (RT-PCR) and fluorescence in situ hybridization (FISH), and addressed the expression and distribution of fusion genes among the subtypes of Chinese adult patients with de novo AML. Multiplex RT-PCR assays were performed on 477 samples from newly diagnosed AML patients, and cytogenetic data were obtained from 373 of them by R or G banding techniques and those in some cases were confirmed by FISH. The PCR products in some suspected cases were tested by two-directional sequencing. The results showed that except unqualified samples, fusion genes were detected by multiplex RT-PCR in 211 of 474 patients (44.51%), including AML1-ETO, CBFβ-MYH11, PML-RARα, PLZF-RARα, NPM-RARα, MLL rearrangements, BCR-ABL, DEK-CAN, SET-CAN, TEL-PDGFR, TLS-ERG, AML1-MDS1 (EVI-1). In 373 patients, who took both multiplex RT-PCR and karyotype analysis, the detection rate of chromosomal aberrations by using multiplex RT-PCR and karyotyping was 160/373 (42.89%) and 179/373 (47.98%) respectively, and the combination could optimize the detection rate of clonal genetic abnormalities to 216/373 (57.90%). The PCR results from 11 cases "normal" in karyotyping but abnormal in RT-PCR for MLL rearrangements were confirmed by two-directional sequencing. It is concluded that karyotype studies remain the cornerstone for genetic testing; conventional cytogenetics and molecular-based methods are complementary tests for the detection of clonal genetic aberrations in AML, especially for the cryptic or submicroscopic aberrations. Once a genetic marker has been identified by combined analysis, it could be used to monitor residual disease during/after chemotherapy, by quantitative RT-PCR and/or FISH.

Objective To investigate the clinical and pathological characteristics of atypical polypoid adenomyoma (APA) for improvement of the diagnosis, different diagnosis and treatment of the disease. Methods The clinical data, pathological characteristics, and the follow-up information were retrospectively analyzed in 27 cases of APA admitted in Peking Univeristy People′s Hospital from 2007 to 2016. Results The median age was 42.6 years old (range 25-60 years old). Fifteen patients were nullipara, 2 patients were postmenopausal. The most common presenting symptom was abnormal uterine bleeding (81%,22/27). Leisions were obtained by using hysteroscopy in 23 cases, hysterectomy 3 cases and dilatation and curettage 1 case. Fertility preserving treatments were performed in 10 patients who had strong desire for fertility, among which 1 case progressed into endometrial carcinoma. Among 15 patients underwent hysterectomy and (or) bilateral salpingo-oophorectomy, 9 cases of them had endometrial atypical hyperplasia. Endometrial carcinoma along with APA were found in three patients, 2 cases of them underwent hysterectomy and bilateral salpingo-oophorectomy and pelvic lymphadenectomy, the other one received medication for fertility preservation. Follow up information were available in 24 cases(89%,24/27)with a median follow up of 46 months (range 4-108 months), 1 case recurred and 1 case progressed into endometrial carcinoma. One case died of other malignancy, while the other patients were alive. Conclusions APA is a rare uterine neoplasm mixed with epithelial and mesenchymal component. It occurs mostly in childbearing-age women and its diagnosis is dependent on pathology. Although it′s clinical course is benign, there is risk of co-existance of endometrial carcinoma and endometrial atypical hyperplasia. For those who has desire of fertility, the treatment strategy is completely removed the lesion and closely followed up. For those who do not desire to preserve fertility, hysterectomy may be an option.

Objective To explore the method of endovascular therapy for complicated aortic dissections.(Methods) The clinical data of 25 patients with complicated aortic dissections were analysed retrospectively.Results The patients′ ages ranged from 31-72 years with a mean of 50.2 years.Among the 25 cases,6 cases had severe ischemia of mesenteric artery,5 cases had renal artery ischemia,4 cases had severe(ischemia) of both legs,3 cases had renal arteries ischemia combined with superior mesenteric artery ischemia,2 had complicated aortic dissection combined with AAA,and in 5 cases the true aortic lumen was totally(compressed) by the false aneurysmal lumen.All patients underwent endovascular therapy,and the instant(technique) was successfully performed in all patients.Endoleak occurred in 3 cases after the stent-graft(deployment),it stopped spontaneously in 2 of them 7 days later,and 1 case with endoleak waiting for(treatment).In the other 22 patients,angiography after the operation showed that all the diseased area were sealed completely,and the viscera arterial blood supply was restored mainly via the true lumen.All the(patients) were cured and discharged.Conclusions In the management of complicated aortic dissections,(endoluminal) technique is simple,less traumatic,safe and has less complications as compared to the traditional operation.Improvement of the endoluminal technique is essential for successful treatment of these complicated cases.

Objective To investigate the incidence and risk factors of acute kidney injury(AKI)after different types of cardiac valve replacement surgery. Methods A single cohort of 1113 patients who received cardiac valve replacement surgery from April 2009 to March 2010 in Zhongshan Hospital,Fudan University were prospectively analyzed.Multivariate Logistic regression analysis was used to evaluate possible risk factors associated with post-operative AKI.Akl was defined as a relative 50% increase or an absolute increment of 26.4 μmol/L in Scr within 48 hours and/or urine volume <0.5ml·kg-1·h-1 up to 6h.Results Of the 1113 patients, the incidence of AKI was 33.24%.In-hospital mortality of AKI patients was 6.49%,which was 5.373 times higher than that of non-AKI patients(P<0.01).The incidence of AKI in patients who simultaneously received cardiac valve replacement and coronary artery bypass grafting was 75.00%,which was significantly higher as compared to other types of valve replacement surgery(P<0.01).Unconditional multivariate Logistic regression analysis revealed that male,old age,long extracorpeal circulation (CPB)time(≥120 min)and combined with coronary artery bypass grafting surgery were the independent predictors of AKI episodes,and the corresponding OR values were 1.455,2.110,1.768 and 2.994 respectively. Conclusions AKI is a common and serious complication after cardiac valve replacement surgery.Patients who received combined cardiac surgery as valve replacement and coronary artery bypass grafting have higher incidence of AKI.Old age,male,long CPB time(≥120 min)and combined with coronary artery bypass grafting surgery are the independent risk factors of post-operative AKI for patients undergoing cardiac valve replacement surgery.

Objective To discuss the feasibility and clinical outcomes of mini-open reduction through lateral deltoid muscle and locking plate fixation in treatment of proximal humeral fractures.Methods A retrospective study was carried out on 39 patients with proximal humeral fractures treated with mini-open reduction through lateral deltoid muscle and locking plate fixation from September 2012 to September 2015.There were 7 males and 32 females,with a mean age of 66.8 years (range,33-86 years).According to the Neer's classification system,there were 26 patients with two-part fracture and 13 with three-part fracture.visual analogue scale (VAS),Constant-Murley shoulder score,time of bone healing and complications were evaluated for all patients.Results All patients were followed up for 12-48 months (mean,21.3 months).All fractures were proved to be bone healing with duration of (12.0 ± 2.7) weeks.The VAS was improved from preoperative (5.7 ± 1.0) points to (0.9 ± 0.6) points at the final follow-up (P ＜ 0.05).The Constant-Murley shoulder score was increased from preoperative (42.3 ±5.1) points to (89.2± 2.5)points at the final follow-up (P ＜ 0.05).Ranges of shoulder motion were improved with satisfactions.There were no complications like axillary nerve injury,loss of reduction,nonunion or humeral head necrosis.Conclusion For proximal humeral fractures,the miniopen reduction through lateral deltoid muscle and locking plate fixation has advantages of minimal invasion,excellent shoulder function,high rate of bone healing and low incidence of complications.
