Objective To prevent misdiagnoses of brucellosis and misjudgment of brucellosis outbreak through differential diagnosis between influenza and brucellosis of three new cases who were in the same work unit and underwent the longest latent period.Methods Contact history of the three new cases was investigated epidemiologically and physical examination and blood test were taken.Brucellosis antibodies of the cases and abortion cow were tested by serum tube agglutination test (SAT),and pathogen was isolated.The tonsilla and pharyngeal secretion substance of cases were collected for detection of influenza virus RNA by real-time PCR.Results The cases had contact history with brucellosis abortion cattle and/or the animal contaminated environment,and had a fever,fatigue and other symptoms.Total blood cell(WBC) was normal and proportion of lymphocyte was increased.The antibody titer in SAT test was 1:200(+++),but pathogen isolation was negative for all three cases.Brucellosis antibody of abortion cow was positive and antibody titer was 1:800 (++).The test of Bv RNA of influenza virus was positive in the three cases.Conclusions The three cases are brucellosis latent infection combined with influenza and we have excluded a misjudgment of pestilence of human brucellosis outbreak.

Objective To analyze the clinical and X-ray manifestations of sclerosing adenosis of the breast,and to evaluate the val-ue of preoperative differential diagnosis between the sclerosing adenosis and the breast cancer combined with pathology.Methods X-ray manifestations and clinical features of 25 patients with the sclerosing adenosis of the breast confirm by surgical pathology were analyzed retrospectively.Then the X-ray manifestations and clinical features were compared with the pathological results.Results Total 25 patients suffered from the sclerosing adenosis of the breast.Among them,2 cases were bilateral sclerosing adenosis,23 ca-ses were unilateral sclerosing adenosis,6 cases with epithelial atypical hyperplasia,4 cases with intraductal papilloma,7 cases with fibroadenoma nodule formation,and the rest with the pure sclerosing adenosis.X-ray manifestations:7 cases presented the medium density nodular shadows with blurred and irregular edges,1 6 cases showed the star-shaped shadows of which 6 cases were the“black stars”,3 cases of“white stars”.One in 7 cases can only see a star shadow,another was unclear or the form was varied.1 3 patients showed the calcification among 4 cases presented the small clusters of distribution with needlepoint-like calcification,2 cases of bulky curved calcification,and the rest with scattered and regional distribution of dot,needlepoint-like calcification.Conclusion Combined with clinical manifestations,the breast X-ray plays an important role in the differential diagnosis of sclerosing adenosis and the breast cancer.

Objective:To investigate the prevalence of Cluster-B personality disorders in university students. Methods: 1. Personality Diagnostic Questionnaire (PDQ+4) was administered to a sample which consisted of 3140 university students to screen personality disorder subjects. Cluster-B personality disorder subjects were finally diagnosed by conducting bland semi structured interview using Personality Disorder Interview-IV (PDI-IV) four to six weeks after the first administration. Results: The total prevalence of Cluster-B personality disorders among 3140 subjects of university students was 1.21% with 38 subjects met the diagnostic criteria of Cluster-B personality disorders. One female subject met the criteria of Antisocial Personality Disorder (APD), 21 Borderline Personality Disorder (BPD), 20 Narcissistic Personality Disorder (NPD), and 8 Histrionic Personality Disorder (HPD). The prevalence of BPD, NPD and HPD were 0.67%, 0.64% and 0.25% respectively. Ten subjects met the criteria of more than one personality disorder; the comorbidity rate was 26.3%. Conclusion: The prevalence of Cluster-B personality disorder in university students is lower than in general population reported by foreign researchers.

Objective To explore the epidemiological characteristics of malaria in Liaoning Province from 1951 to 2014,so as to provide the evidence for further control of the disease. Methods The data of registered malaria cases in Liaoning Province from 1951 to 2014 were collected and analyzed with epidemiological methods. Results From 1951 to 2014,there were report-ed malaria cases each year. The peaks of incidence were in 1953,1962 and 1973,the incidence rates were 136.67/100000, 256.81/100000 and 35.89/100000 respectively and the numbers of patients were 27862,65460 and 11523,respectively. From 1977 to 2014,the incidence rates were all less than 1/100000. From 1951 to 1980,the occupations of patients were main-ly farmers,and from 1981 to 2014 were mainly workers,farmers and exported laborers. Conclusion The malaria endemic situ-ation in Liaoning Province experienced the periods from outbreaks to basically elimination,and the long-term surveillance will be the further working emphasis.

To analyze the genetic characterization of epidemic mumps virus strains in Liaoning Province and provide the basis for mumps control. A total of 32 mumps viruses strains were isolated during 2008-2104. The fragment of SH genes and HN genes were amplified by RT-PCR, the PCR products were sequenced and analyzed. Basing on the 316 nucleotides of SH gene, The phylogenetic analyses were processed with the data of WHO mumps reference strains downloaded from GenBank and 32 mumps viruses strains. It showed that the 31 mumps virus strains belong to F genotype except MuVi/Liaoning. CHN/16.11 which was G genotype . Comparing to the A reference strains (Jeryl-Lynn and S-79), F genotype MuV were mutated on 12 amino acids sites and 27 amino acids siteson on HN gene. F genotype MuV added one N-glycosylation site in 464th-466th amino acids. The antigenic sites on HN were mutated on 121th, 123th, 279th, 287th, 336th, 356th and 442th. Maybe, it will influence the MuV antigenic.

To wished to characterize the hemagglutinin (H) gene of the measles virus epidemic strain H1a in Liaoning Province (China) from 1997-2014 to provide a basis for the control and elimination of measles. All 63 measles virus strains were the H1a genotype. Fragments of the H gene (1854 nucleotides) and nucleoprotein (N) gene (450 nucleotides) were amplified by reverse transcription-polymerase chain reaction (RT-PCR) and the PCR products sequenced and analyzed. Phylogenetic-trees were constructed with reference strains of the genotype-H measles virus downloaded from GenBank, including Chinese measles virus strains isolated in 1993-1994 and the vaccine reference strains S-191 and C-47. Sixty-three strains of the measles virus in 1997-2014 belonged to genotype H1a. The mean evolutionary rate for gene N-450 was higher than that for the H gene. All 63 strains of the measles virus were mutated from: serine (Ser S) to asparagine (Asn N) in the 240th amino acid; arginine (Arg R) to glycine (Gly G) in the 243th; and tyrosine (Tyr Y) to Asn N in the 481th amino acid. All measles virus strains in cluster 2 were mutated from proline (Pro P) to leucine (Leu L) in the 397th amino acid. The other neutralization sites showed no apparent difference when comparing the nucleotides/amino acids of the H gene of S191 vaccine strains.

Objective To explore the altered functional connectivity of the amygdala in adolescents with internet gaming disorder (IGD) using resting state functional connectivity (rsFC) and dynamic functional connectivity (dFC) analysis.Methods Thirty adolescents with IGD (IGD group) and 30 demographically matched healthy controls (HC group) were recruited.The right and left amygdala were selected as seed regions,the rsFC and dFC between 2 groups were calculated.The regions showing altered connectivity in IGD were adopted as ROIs for correlation analysis.Results Compared to HC group,IGD group had higher rsFC with the right amygdala over the right inferior temporal,middle temporal gyrus,middle frontal gyrus,lower rsFC with the right amygdala over the left inferior temporal,superior temporal and the right inferior occipital gyrus,superior occipital gyrus.The IGD group had lower rsFC with the left amygdala over the right rectal gyrus and thalamus.Compared to HC group,the IGD group showed higher dFC variance with the left amygdala over the right middle temporal and the left media frontal gyrus,and lower dFC variance over the right precuneus,inferior parietal lobe,posterior cingulate and the left postcentral gyrus.The IGD group showed higher dFC variance with the right amygdala over right middle frontal gyrus and lower dFC variance with the right amygdala over the right middle temporal,the left media frontal gyrus and paracingulate cortex,inferior parietal lobe.The rsFC between the left amygdala and right rectal gyrus was negatively correlated with Chinese Internet Addiction Scale (CIAS) scores.The dFC variance between the left amygdala over the left postcentral gyrus was positively correlated with CIAS scores.The dFC variance between the left amygdala and the right inferior parietal lobe were negatively correlated with CIAS scores.Conclusion The amygdala participates in the development of IGD.

To design teaching course of problem-based learning (PBL) combined with case-based learning (CBL) for standardized training of clinicians based on clinical decision thinking mode (CDTM) of diagnosis and treatment process for primary liver cancer. The CDTM of treatment choice for primary liver cancer is multi-scheme selection model. The general decision rule includes decision condition, action plan and decision tree. For the theoretical study of clinical decision rules, it is suitable to design PBL teaching, but it is suitable to design CBL teaching course for clinical decision-making practice. The teaching course of PBL combined with CBL is conducive to improving the ability of clinicians' clinical decision thinking step by step.
