The levels of the antibody response against,classic swine fever (CSF) vaccine were measured by blocking ELISA at different time for pigs vaccinated with CSF vaccine (CSFV group,n= 3),pigs inoculated with porcine eircovirus type 2 (PCV2) and with CSF vaccine two weeks later (when PCV2 viremia was detected by PCR,PCV2/CSFV group,n=3),or inoculated with both CSF vaccine and PCV2 at the same time (CSFV/PCV2 group,n=3),respectively.And distribution of genome or antibodies specific to PCV2 of the PCV2 infection group,PCV2/CSFV group and CSFV/PCV2 group were also detected by indirect ELISA or PCR,respectively.The results showed that experimental infection of PCV2 was successful.In pigs inoculated with both PCV2 and CSF vaccine,the antibody response to CSF vaccine was significantly lower than that of animals treated with CSF vaccine vaccination alone at 52 days postinoculation (DPI).The average titers of antibodies against CSFV in animals of CSFV group were obviously higher than those of the PCV2/CSFV or CSFV/PCV2 group at 49 and 52DPI,respectively.The positive rate of antibodies against CSFV in pigs of CSFV group was 100% in comparison with that of animals inoculated with PCV2 and the vaccine (only 67%).The results suggested that the infection of PCV2 could suppress the antibody response to classical swine fever vaccine.

The combined use of chemometrics and chemiluminescence（CL）measurements,with the aid of the stopped-flow mixing technique,developed a simple time-resolved CL method for the simultaneous determination of captopril（CPL）and hydrochlorothiazide（HCT）.The stopped-flow technique in a continuous-flow system was employed in this work in order to emphasize the kinetic differences between the two analytes in cerium（IV）-rhodamine 6G CL system.After the flow was stopped,an initial rise of CL signal was observed for HCT standards,while a direct decay of CL signal was obtained for CPL standards.The mixed CL signal was monitored and recorded on the whole process of continuous-flow/stopped-flow,and the obtained data were processed by the chemometric approach of artificial neural network.The relative prediction error（RPE）of CPL and HCT was 5.9% and 8.7%,respectively.The recoveries of CPL and HCT in tablets were found to fall in the range between 95% and 106%.The proposed method was successfully applied to the simultaneous determination of CPL and HCT in a compound pharmaceutical formulation.

In order to further understand the cognitive attitude of different groups towards the rank of rights and interests in medical decision-making and its influencing factors, and provide theoretical reference for the practice of medical decision-making, this study conducted convenience sampling through the questionnaire star enterprise edition. The collected data were descriptive statistical analysis with SPSS 21.0 software and joint hypothesis testing. The results showed that there were differences in the cognition of religious beliefs on the same individual’s rights and interests rank among the sample population (P<0.05). There were differences in the cognition of professional title, working years and institution level on the attitude of rights and interests rank in the group of medical institutions (P<0.05). In the ranking of the importance of individual rights usually involved in medical activities, the rights to life, health and equality were the most important. Most people can rationally view the rights and interests of doctors, patients and stakeholders. In medical decision-making, we should adhere to the principle of right rank, give priority to safeguarding the right to life and give consideration to fairness and justice. In the face of conflicts of interest, we should do a good job in value evaluation, safeguard the reasonable interests of patients and give consideration to the demands of family members.

Objective To investigate the molecular epidemiology and clinical characteristics of human bocavirus in children with acute respiratory tract infection in Shanghai,China.Methods Between January 2012 and December 2012,271 nasopharyngeal aspiration (NPA) samples were collected from children who had been hospitalized for acute respiratory tract infection at Shanghai,China.HBoV NS1 gene was detected by the nested polymerase chain reaction.In the further,other common respiratory viruses (HRV,RSV,ADV et al) was screened in HBoV positive samples,All PCR positive products were sequenced and phylogenetic analysis.Results The overall frequency of HBoV,infection was 11.4％.21of 31 HBoV positive sample tested were mix-infection.HBoV was detected from all over year.Children with HBoV varied in age from 4 months to 4-years (median age,17 months).The clinical diagnoses of HBoV positive patients included acute upper respiratory tract infection and lower respiratory tract infection.The clinical presentations of HBoV positive children included fever,cough,sputum production,diarrhea,vomiting;pharynx engorgement,crackles,wheezing.There being a statistically significant difference in the detection rates of HBoV between the outpatients and inpatients.The HBoV NS1 gene sequences phylogenetic analysis revealed that 29 HBoV1 NS1 sequences shared 99％-100％ nucleotide identity with the human bocavirus strain,whereas the amino acid identity was 96％-100％.The two HBoV2 NS1 sequences shared 99％ nucleotide sequence identity with HBoV2 strain FJ170282 respectively.Conclusions Human bocavirus was distributed in Shanghai region,HBoV1 was dominant and HBoV2 was detected at the first time.The symptom and clinical diagnoses has no specificity with patients with other common respiratory viruses.

Objective: To explore the safety and feasibility of associating diaphragm resection and liver-diaphragmatic metastasis lesions resection for patients with advanced ovarian cancer. Methods: Retrospectively analysis 83 cases(98 times) of advanced ovarian cancer with liver-diaphragmatic metastasis between January 2012 and December 2016 at Department of Liver Surgery, Peking Union Medical College Hospital.The patients were aged from 19 to 75 years.Surgical procedure included metastatic lesions resection(43 times) and stripping(55 times). Operation status, post-operative complications, pathology results and follow-up of the patients were analyzed. Results: Fifteen patients received twice surgical treatment and 68 patients received one time surgical treatment. Postoperative hemorrhage in chest and between liver and diaphragm was not occurred in all cases.Dyspnea and low oxygen saturation were occurred in two cases of stripping patients and 1 case of metastatic lesions resection patients.Results of CT examination indicated that there was medium to large amount of ascites in right chests.The symptoms were relieved after placing thoracic closed drainage.Other patients were recovered smoothly.All patients were diagnosed as ovarian cancer by pathological examination. Conclusion Associating diaphragm resection is safe and feasible for liver-diaphragmatic metastasis lesions from ovarian cancer.
