Objective To study the biological effects of dose radiotherapy for primary liver cancer patients with stereotactic body portion.Methods 80 patients with primary liver cancer were selected.According to a random number table method, all patients were divided into observation group and control group,40 patients in each group.All patients were treated with stereotactic body radiotherapy treatment, the observation group was treated with high dose, while the control group received low-dose.The radiotherapy effects of different doses were analyzed and compared.Results After treatment, the effective rate of the observation group was 77.5%,which of the control group was 55.0%, ,the difference between the two groups was statistically significant (x2=4.528,P=0.033).After treatment for 6 months,1 year and 2 years, the survival rates of the observation group were 77.5%,75.0%,72.5%, which were significantly higher than 55.5%,52.5%,50.0% of the control group (P<0.05).The incidence rate of adverse reactions of the observation group was 42.5%, which was significantly lower than 72.5% of the control group (x2=7.365,P=0.006).Conclusion Stereotactic body radiotherapy treatment with different therapeutic dose has different treatment efficacy, high-dose SBRT treatment has significantly higher efficacy, survival rate and lower adverse reactions, which is worthy of clinical application.

Objective To understand the characteristics of molecular epidemiology of enterovirus 71(EV71) in children with hand, foot and mouth disease (HFMD) in Shanghai area during the first half year of 2009. Methods Seventy-three throat swabs and 38 stool samples were collected from 95 hospitalized children with clinical diagnosis of HFMD in Children's Hospital of Fudan University during April to May 2009. TaqMan real-time reverse transcription-polymerase chain reaction (RT-PCR) and nest RT-PCR were used to detect EV71 VP1, followed by gene sequencing analysis. Results Six of the 73 throat swabs were EV71 positive with the detection rate of 8.2%. In the 38 stool samples, 24 were EV71 positive with the detection rate of 63.2%. Twenty-eight nested RT-PCR positive samples were sequenced and the genetic analysis showed that 27 were C4 subtype,which were absolute dominant strain and the other one was C2 subtype. The isolated strain from a fatal case was C4 subtype and there was no obvious mutation found in VP1 region. Conclusions EV71 is an important pathogen in HFMD children in Shanghai area during April to May 2009. C4 subtype strains are absolutely dominant, and accompanied by epidemic strains of subtype C2.

Objective To evaluated the role of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) in the diagnosis of thoracic tuberculosis.Methods The study was retrospective,from September 2009 to September 2012,38 patients who underwent EBUS-TBNA were finally diagnosed of thoracic tuberculosis,with enlarged hilar or mediastinal Iymph nodes on chest enhanced computed tomography(≥ 1.0 cm).Patients in whom EBUS TBNA was nondiagnostic subsequently underwent surgical biopsy.All the patients had a minimum of 6 months clinical and radiologic follow-up.Results EBUS-TBNA was performed on a total of 88 lymph node stations in 38 patients.Of the enlarged lymph nodes,60(68.18％) were located in the mediastinal region and the remaining 28 (31.82 ％) around the hilum or interlobar area.Of the 38 patients,EBUS-TBNA achieved definitive diagnosis in 34 patients(89.47％).EBUS was well tolerated by all of the patients with no complications.Conclusion EBUS-TBNA is a safe procedure with a high yield for the diagnoses of thoracic tuberculosis.

This study is to determine six chlorogenic acids (chlorogenic acid, 5-O-caffeoylquinic acid, 4-O-caffeoylquinic acid, 3,4-di-O-caffeoylquinic acid, 3,5-di-O-caffeoylquinic acid and 4,5-di-O-caffeoylquinic acid) by quantitative analysis of multi-components with a single marker (QAMS). Chlorogeinc acid was used as internal reference to calculate the relative correction factors (RCF) of five compounds. Then the ruggedness of relative correction factors was tested on different instruments and columns. Meanwhile, a total of 4 batches of Lonicerae Flos and 20 batches of Lonicerae Flos extract with five different processing procedures were analyzed by external standard method (ESM) and QAMS, respectively. The ruggedness of relative correction factors was good. And the analytical results calculated by ESM and QAMS showed no difference. The quantitative method established was suitable for the quality evaluation of Lonicerae Flos extract.

A series of isoindoline derivatives were designed, synthesized, and evaluated for their double inhibitory activities. All of them were new compounds, and their structures were confirmed by 1H NMR and HR-MS. Preliminary in vitro pharmacological tests showed that all compounds exhibited 5-HT or NE reuptake inhibition activity. Among the tested compounds, compound I-3 exhibited potent inhibitory activity against 5-HT and NE reuptake in vitro, and exhibited potent antidepressant activity in vivo. These compounds designed can be further optimized for finding more potent 5-HT/NE dual reuptake inhibitors and antidepressant candidates as well.

Objective To understand healthcare-associated infection(HAI)in a maternal and child health care hos-pital,so as to provide scientific evidences for further targeted surveillance.Methods A cross-sectional survey was performed by bedside visiting and medical record reviewing.Results Of 768 hospitalized patients,9(1 .18%)had HAI,the top 3 highest prevalence rates were found in obstetrical intensive care unit (9.09%),neonatal intensive care unit (5.80%)and gynecological department II(2.22%).Antimicrobial usage rate was 30.34%(n=233),134 of which (57.51 %)were prophylactic use,165 were mono-therapy(70.82%).A total of 5 pathogenic bacteria were isolated,the number of Streptococcus agalactiae ,Klebsiella pneumonia ,Enterococcus faecalis ,and Staphylococcus saprophyticus was 2,1 ,1 ,and 1 respectively,except Streptococcus agalactiae ,the other 3 strains were multidrug-resistant organisms(MDROs).Conclusion Surveillance on MDRO infection should be paid much attention,the oc-currence of MDRO infection should be reduced through targeted and bundle intervention.

Purpose To investigate the expression of tumor buds and its relationship with clinicopathological characteristics in endome-trial carcinoma. Methods 47 cases of endometrial carcinoma were observed and analyzed by means of clinicopathologic data and im-munohistochemical staining. The connections between tumor buds and clinicopathologic parameters were studied by statistics. Results Of the 47 endometrial carcinoma cases, tumor buds were seen in 18 cases. Tumor buds were correlated with histological grade, lymph node metastases, vascular invasion, Ki-67 index and survival. There were no associations between tumor buds with age, tumor size, pTNM stage or myometrial invasion depth. Immunohistochemistry demonstrated that the level of N-cadherin, vimentin in bud cells was higher than normal carcinoma cells while the level of CK(AE1/AE3),β-catenin and E-cadherin got the opposite results. Conclu-sion Tumor buds may play an important role in the progression of endometrial carcinoma. The immunohistochemical features of bud cells indicated that tumor buds may be a key step in epithelial-mesenchymal transition.

The hom gene encoding for homoserine dehydrogenase was amplified from the genomic DNA of Corynebacterium glutamicum ATCC 13032.After the kanamycin-resistant gene(Km)cassette from plasmid pET28a was inserted into the center of hom,the hom::Km cassette was then electroporated into the competent cell of C.glutamicum ATCC 13032.And kanamycin-resistant clones were obtained.PCR was performed to confirm whether the Km gene was integrated into the hom gene of these clones and the recombinant strains of hom-disrupted were screened out.Fermentation results showed that the lysine yield of the hom-disrupted strain C.g-hom::Km-8 reached 4.7 g/L,which was 6.7 times that of C.glutamicum ATCC 13032.
