Objective To investigate the epidemiological and clinical characteristics of human coronovirus (HCoV ) infection in hospitalized children with acute lower respiratory tract infection (ALRTI)in Shanghai.Methods A retrospective cohort study was conducted between October 2009 and September 2012.Five hundred and fifty-four cases of ALRTI in children under 5 years were enrolled. HCoV and other respiratory viruses in archival nasopharyngeal aspirate specimens were detected by a commercial Seeplex RV12 ACE detection kit.HCoV pan-family reverse transcription polymerase chain reaction (PCR)was performed to screen all known six HCoV,including HCoV-229E,HCoV-OC43, severe acute respiratory syndrome (SARS)-CoV,HCoV-NL63,HCoV-HKU1 ,and real-time PCR was performed to screen Middle East respiratory syndrome (MERS)-CoV.MEGA5 .0 software was used to perform sequence alignment and phylogenetic tree analysis.Results In 554 samples,at least one virus was identified in 273 cases (48.56%)and HCoV was detected in 18 cases (3.25 %),among which 13 were HCoV-OC43/HKU1 positive,5 HCoV-229E/NL63 positive.No high pathogenic MERS-CoV and SARS-CoV were detected.The median age of 18 children with HCoV infection was 18 months (1 -48 months)with 12 boys and 6 girls.Seventeen cases had fever,11 cough,9 tachypenea and 1 wheeze. Seven received oxygen therapy,and 6 were admitted to intensive care unit for treatment.Two who was in ordinary ward were coinfected with adenovirus and human rhinovirus.All 18 cases recovered or improved on discharge.Six was infected in autumn,5 in winter,3 in spring and 4 in summer.Of 8 HCoV-positive samples which were sequenced,each 3 samples belonged to HKU1 and 229E subtypes,respectively,and each 1 belonged to OC43 and NL63 subtypes,respectively.Conclusions HCoV is a relatively common viral pathogen among hospitalized young children with ALRTI in Shanghai.No high pathogenic MERS-CoV is detected.HCoV can cause severe infection with favorable outcome.

Angioimmunoblastic T-cell lymphoma (AITL) is a rare subtype of peripheral T-cell lymphoma (PTCL) with aggressive behaviour and poor prognosis.Due to the rarity of the disease,few prospective controlled randomized clinical trials were conducted,and the standard therapeutic option for AITL has not been established.Although conventional anthracycline-based chemotherapy achieves response rates of up to 50 ％,most of the patients relapse,the median survival time and overall survival rate are unsatisfactory.Recent studies have demonstrated that hematopietic stem cell transplantation and cyclosporine show promising efficacy in the treatment of AITL.This current review mainly focused on the advance of treatment for AITL.

Objective To analyse the prevalence, etiology, presentation, preserving ovary and progonosis of cervical cancer in women under 35 years old. Methods The clinical information of 174 patients were retrospectively analysed.Results The percentage of new cervical cancer cases from 1991 to 2001 was 1.2%, 1.2%, 4.3%, 4.2%, 4.6%, 4.5%, 7.3%, 9.0%, 10.7%, 9.4%, 10.8%, respectively( P 0.05).For patients with two or more risk factors, it was 68%, 1/7, respectively ( P

MicroRNA is a type of endogenous noncoding small molecular RNA with a length of 19-25 nucleotides. MicroRNAs are involved in almost all key biological processes, such as cell proliferation, differentiation, apoptosis, and hematopoiesis, via repres-sion of target gene expression. Acute lymphoblastic leukemia (ALL) is the most common type of pediatric cancer. It is a heterogeneous disease with different clinical signs, morphology, immunophenotype, and cytogenetics. Currently, several microRNAs have implicated aberrant expression in ALL and play an important role in cancer initiation and development. MicroRNA expression pattern is associated with clinical feature, prognosis, and treatment. Therefore, microRNAs could act as a novel marker to help scientists learn about the pathogenesis of ALL and to provide more effective treatment options.

Objective To investigate the antileukemia effect of Prunella vulgaris Injection(PVI) in order to offer experimental data for the treatment of leukemias with PVI in clinic.Methods Inhibition of PVI on K562 cell proliferation and IC_(50) value was assayed by MTT assay.The growth curve of K562 cells was drawn also.The cellular morphology was observed by invert microscope,Giemsa staining,and MTT assay.The apoptosis induced the effect of PVI to K562 cells was observed by trypan-blue exclusion test and flow cytometer(FCM).The expression of apoptosis related protein bcl-2 and bax was measured by immunocytochemistry,and the quantitative analysis was made with figure analysis system.Results PVI obviously inhibited the proliferation of K562 cells in a dose-dependent manner(r=0.985 0).The IC_(50) was 0.113 mg/mL.(After) K562 cells were treated with PVI(50 mg/mL),the morphological characters of apoptosis were observed.The results of FCM showed that the apoptosis rats [(37.15?1.46)%] in the treatment group were significant higher than that in control group [(5.56?0.68)%](P

More and more studies have found that EBV infection is closely related to the occurrence, development, treatment and prognosis of lymphoma. The treatment of EBV-positive lymphoma bases mainly on combined chemo-radiotherapy together with ganciclovir, acyclovir and other antiviral drugs. Also there are novel ways to treat EBV positive- lymphoma including CD70 monoclonal antibody, butyrate, etc. The only way to prevent EBV infection is to inoculate anti-viral vaccine. The criterion of treating EBV positive-lymphoma remains to be further investigated.

Clinical Clerkship is the necessary stage from theory to clinical practice,As teaching hospital of Nanjing Medical University.we explore various kinds of methods of clinical practice quality improvement by emphasizing practice training,developing multiform teaching activities,highhghting autonomic learning and strengthening intemship management.

To evaluate the ultrasound imaging characteristics and diagnostic criteria for acute abdominal Meckel's di- verticulum disease (MD), we retrospectively analyzed the ultrasonic characteristics, clinical data of 58 cases of pathologically proved MD from January 2009 to May 2012. We found that among all the 58 patients, 21 patients were diagnosed with the preoperative clinical diagnosis of MD. Fourteen cases of MD inflammation with acute appendicitis were evaluated by pathological examinations after the surgery. We also found 4 cases of MD with perforation, 15 cases of MD with intussusceptions, 14 cases MD with intestinal obstruction, 5 cases of MD secondary to intestinal obstructionor intestinal necrosis, and 5 cases of MD without any obvious complications. Emergency ultrasound examinations revealed 8 cases of simple MD, 1 case of MD with intussusceptions, 9 cases of MD with acute appendicitis, 12 cases of MD with intestinal obstruction, 2 cases of MD with intussusceptions and intestinal obstruction, 1 case of MD with omphalocele and 1 case of MD with abdominal abscess. The emergency sonographic findings suggested that MD was relatively fixed bowel or thick-walled cystic mass, with one end connected to small intestine, and the other end connected to the blind side, at the periumbilicus region or at the lower right abdomen. A conclusion could be drawn that MD is difficult to be detected by ultrasound (detection rate was about 15. 5%), and MD with complications such as intussusceptions, intestinal obstruction, acute appendicitis can usually be more easily detected (detection rates were 24.1%, 24.1% and 15.5%, respectively). Sonography is a simple, effective way to make diagnosis and differential diagnosis of MD with different acute abdomen symptoms from other disease.

Chemotherapy- induced peripheral neuropathy (CIPN) can be caused by many commonly used chemotherapeutic agents, such as taxanes, vinca alkaloids, platinum drugs, thalidomide,and also by newer agents such as bortezomib. Both animal experiments and clinical studies are being conducted to investigate strategies for preventing CIPN or ameliorating established CIPN without affecting the antitumor efficacy of chemotherapy. Treatments using calcium and magnesium infusions,glutathione,lipoid acid are being evaluated for their clinical application.

Objective To analyse CT findings of pleural mensothelioma caused by crocodolite in their living environment.Methods CT findings of malignant pleural mensothelioma in 55 cases were reviewed and analyzed retrospectively.Results Of 55 cases there were localized pleural mensothelioma in 1 accompanied with less pleural effusion and malignant diffuse pleural mensothelioma in 54 ,of which 13 cases had no pleural effusion,30 cases had less or more effusion and 11 cases had a large amount of pleural effusion.In 4 cases,mensotheliomas localized in low-right thorax accompanied pleural effusion in left thorax.The CT findings of these four patients were pleural thickening more than 2 cm.The lesion was manifested as decorative border,nodule and mass of soft tissue and there was much enhancement.Conclusion CT scan is very helpful in detecting the location,extent of pleural mensothelioma and follow-up of patients.
