Objective To explore the reconstructive methods of benign bone tumor defects in proximal joint. Methods Operative treatment was performed in 11 cases with benign bone tumor defects in proximal joint, a-mong whom 4 cases were treated by curettage,cauterization of wall and bone grafting,3 cases were treated by filling branch through segment fibula transplantation with vascular,2 cases were treated by fibula head transplantation with vascular to reconstruct the glenohumeral joint and rediocarpal joint, and 2 cases were treated by artificial joint re-placement. Results The follow-up ranged from 1.5 to 6 years. All of cases got excellent bone unioned without re-lapse and 2 cases of them developed with little limitation in joint function. Conclusion The importance and recon-structive achievement of fibula transplantation in treating the benign bone tumor defects in proximal joint should be thought fully. The indication of artificial tumor prosthesis replacement should be strictly mastered.

Objective: To summarize the characteristics of arrhythmia with the relevant factors affecting its prognosis in patients of apical hypertrophic cardiomyopathy (AHCM). Methods: A total 283 AHCM patients with echocardiography or cardiac magnetic resonance (CMR) conifrmed diagnosis in our hospital from 2005-01 to 2012-08 were summarized. The patients were divided into 2 groups: With arrhythmia group, n=103 and Without arrhythmia group,n=180. The endpoint event was followed-up by clinical and telephone visits in both groups and the relevant risk factors affecting AHCM prognosis were investigated by Cox regression analysis. Results: There were 269 patients ifnished the follow-up investigation, 98 in With arrhythmia group, 171 in Without arrhythmia group, and the death rate was 4.08% vs 1.17%, the occurrence of endpoint event was 18.37% vs 5.58%respectively. Cox regression analysis indicated that age (HR=23.051, 95% CI 1.08-1.068,P<0.005), left atrial diameter (HR=4.113, 95%CI 1.002-1.119,P=0.043) and NT-proBNP (HR= 18.653, 95% CI 3.433-26.650,P<0.005) were the independent risk factors affecting prognosis in AHCM patients. Conclusion: Arrhythmia is one of the common presentations of AHCM, it does not have much impact on survival, while it may cause ventricular ifbrillation and increase the occurrence of cardiovascular events.

Clinical application of staphylococcal enterotoxin C2 (SEC2) was restricted during the cure of malignant tumor due to its side-effects. The aim of this study was to obtain SEC2 mutant, preserving the important functional sites responsible for the T-cell stimulatory activities but removing the sites responsible for emetic activity, through truncation of SEC2. It would efficiently solve the question of SEC2 side-effect. According to the results of methyl thiazol tetrazolium (MTT) assay in vitro, novel truncated SEC2 mutant (NSM) efficiently stimulated T-cell proliferation and inhibited the growth of such tumor cells as human colorectal cancer cells (Cx-1) and human breast cancer cells (MCF-7) in vitro. Activities of T cell stimulating and anti-tumor of NSM were similar to those of SEC2. According to results of animal experiments, the mutant no longer induced emetic response even if the dose was a 10-fold excess of the amount of SEC2 required. And also, NSM obviously inhibited the tumor growth in tumor-bearing mice. Therefore, we obtained novel truncated staphylococcal enterotoxin C2 mutant, which could efficiently inhibit the growth of tumor cells. It will become novel anti-tumor agents with the lowest side-effects and best treatment effects in clinic.

Objective: To analyze the sero-epidemiological characteristics of hepatitis B virus among people born during 1994-2001, conducted by the national hepatitis B sero-epidemiological surveys in 2006 and 2014. Methods: Based on the data of the two national hepatitis B sero-epidemiological surveys in 2006 and 2014, people born during 1994-2001 were included into our analysis as this study subjects. The two surveys were conducted in 160 disease surveillance points of 31 provinces (not including Hong Kong, Macao and Taiwan) in China. Face-to-face interviews with the subject by door to door or on the investigation site were conducted by trained staff using standard questionnaires to obtain basic information including birth date, sex, ethnicity, resident place and so on. And then 5 ml venous blood was collected. Enzyme-linked immunosorbent assay (ELISA) reagents were used for HBsAg, anti-HBs and anti-HBc measurements and Abbott micro-particle enzyme immunoassay (MEIA) reagents was used to confirm test. We analyzed HBsAg, anti-HBs and anti-HBc positive rate by gender, ethnicity, urban/rural, eastern/central/western region, birth years and compared the distribution of serum epidemiological characteristics in 2006 and 2014. Results: 19 821 and 4 712 people born during 1994-2001 were involved in 2006 and 2014 national serosurveys of China, respectively. For the people born during 1994-2001, HBsAg positive rate were 2.02% (95% CI: 1.82%-2.21%) in 2014 and 1.95% (95% CI: 1.56%-2.35%) in 2006. Anti-HBc positive rate were 7.94% (95%CI: 7.17%-8.71%) in 2014 and higher than that in 2006 (6.49%, 95%CI: 6.15%-6.83%), especially for the female (8.31%, 95% CI: 7.20%-9.43%), urban (7.45%, 95% CI: 6.38%-8.52%), western region (11.25%, 95%CI: 9.79%-12.71%), minority people (16.02%, 95%CI: 13.47%-18.57%) in 2014 were higher than that of the female (6.29%, 95% CI: 5.81%-6.78%), urban (4.82%, 95% CI: 4.40%-5.24%), western region (7.97%, 95% CI: 7.31%-8.63%), minority people (11.88%, 95% CI: 10.66%-13.00%) in 2006 respectively. Anti-HBs positive rate were 57.80% (95%CI: 57.11%-58.48%) in 2014 and 59.13% (95%CI: 57.72%-60.53%) in 2006. Anti-HBs positive rate of rural (58.80%, 95% CI: 56.83%-60.78%),western region (58.50%, 95% CI: 56.23%-60.78%), minority people (57.20%, 95% CI: 53.76%-60.63%) in 2014 was higher than of rural (52.62%, 95% CI: 51.64%-53.61%),western region (51.73%, 95% CI: 50.54%-52.96%),minority people (41.14%, 95%CI: 39.28%-43.00%) in 2006. Conclusion Anti-HBc positive rate among people born during 1994-2001 in 2014 survey showed a rising tendency than in 2006. The risk of HBV infection was existed. Hepatitis B vaccine catch-up in childhood was necessary.

Objective: To analyze the epidemiological characteristics of HBV susceptible people in 1-29 years old people in 2006 and 2014 in China. Method: Data is from the 2006 and 2014 national sero-survey, and both of them were conducted in 160 disease surveillance points of 31 provinces (excluding Hong Kong, Macao Special Administrative Region and Taiwan province) in China. We used the centralized face-to face investigation method to collect basic information including birth date, gender, ethnicity, resident place, hepatitis B vaccination (HepB) history and so on, and 5 ml venous blood was collected for all subjects to test the sero-markers of HBsAg, anti-HBs and anti-HBc. We definite the HBV susceptible people as the HBsAg, anti-HBs and anti-HBc all negative together. And we use chi-square to analyze the epidemiological characteristics of HBV susceptibility in 1-29 years old young people in 2006 and 2014, and use multiple factors logistic regression to analyze the affect factors on HBV susceptible appearing in people with HepB vaccination. Result: In 2006 and 2014 sero-surveys, the investigated 1-29 year-old people were 49 849 and 31 713, respectively. And compared with 2006, the proportion of HBV susceptible people with HepB among 1-29 in 2014 increased from 20.87% (10 401) to 28.55% (9 055) (χ²=630.69, P<0.001); and the proportion of susceptible people without HepB decreasing from 15.02% (7 485) to 7.66% (2 460) (χ²=953.73, P<0.001). Compared with Han nationality, the high risk of susceptible appearing in minority people after HepB vaccination (OR=1.38). And compared with less than 3 doses HepB vaccination, the more than 3 doses vaccination could reduce the anti-HBs disappearing rate (OR=0.68); Compared with one year after last dose vaccination, the 2-4 years interval (OR=3.33) and more than 5 years interval (OR=6.53) would have high risk for anti-HBs disappearing. All above were P<0.001. In western area, the proportion of susceptible people without HepB (9.58%, 1 047/2 460) was higher than the proportion in eastern (6.30%, 657/2 460) and middle area (7.30%, 756/2 460) (P<0.001). Conclusion The HepB coverage maintained in high level in 1-4 years old children. The HBV susceptible proportion mainly concentrated in 15-29 years old people, and the immunization gap was in western, rural areas and minority peoples.

Objective To evaluate the application effect of nursing management in the follow-up of patients with recurrent acute pancreatitis (RAP).Methods During January 2016 and January 2017,the clinical data of RAP patients admitted in Changhai Hospital of Navy Medical University was collected.Selfcontrol method was used to establish a prospective cohort study.Meticulous nursing management mode was applied to follow up the patients for 12 months.Patients' compliance,symptom improvement,patients' satisfaction and other markers are evaluated using questionnaires to assess the effect of meticulous nursing management once every 3 months.The data over 12 months were collected.Results Sixty-four RAP patients were finally included.The average follow-up period was 19.7 ±3.4 months.Before admission,the average disease course was(4.21 ± 3.95) years.30 patients (46.9％)had a history of drinking;33 patients (51.6％)had a history of smoking.25 patients (39.1％) had abnormal blood lipid and 40 patients (62.5％) had the dietary habit of high lipid and high protein.The etiology included alcohol (n =10,15.6％),high lipid (n =7,10.9％),biliary diseases (n =1,1.6％),idiopathic causes (n =46,71.9％) and abnormal BMI (n =49,76.6％).After the meticulous nursing management,the frequency of pancreatitis,VAS score of pain and alcohol intake situation was obviously lower than before intervention [(0.50 ±0.85) times/year vs(2.77 ±2.52)times/year;(1.84 ±2.54)vs(6.47 ±2.15);2 cases vs 30 cases].The number of patients who took medicine on time and BMI were obviously decreased[(52 cases vs 13 cases;(23.26 ± 3.85) kg/m2 vs (21.92 ± 4.27)kg/m2)],and the differences were statistically significant (P ＜0.01).Patients' satisfaction with this nursing model was 4.90 ± 0.56.Conclusions The implementation of the new meticulous nursing management model can effectively alleviate patient's symptom condition and improve the compliance behavior and life quality of the patients.

OBJECTIVETo analyze the information of the supplementary card for hepatitis B and the laboratory confirmed result of immunoglobulin M antibody to hepatitis B virus (HBV) Core Antigen (anti-HBc IgM) for the suspected acute hepatitis B to evaluate the hepatitis B report data on pilot surveillance.

METHODS200 counties were established in China for hepatitis B pilot surveillance and 63 641 cases were reported. We added a supplementary card in National Notificable Disease Reporting System (NNDRS) and all the reported hepatitis B cases in NNDRS were required to fill the supplementary card. Venous blood 5 ml was collected and a confirmed test of anti-HBc IgM was made for suspected acute hepatitis B. We made confirmed diagnosis for the suspected acute hepatitis B according to the supplementary card information of the reporting card and the confirmed test result of anti-HBc IgM.

RESULTS63 641 hepatitis B cases were reported in 200 hepatitis B pilot surveillance counties in 2013. Among 1 723 cases which were filled with the HBsAg positive within six months in supplementary card, 735 cases were reported as chronic hepatitis B, the proportion was 42.66%. Among 4 582 cases which were filled with anti-HBc IgM positive in supplementary card, 2 436 cases were reported as acute hepatitis B, the proportion was 53.16%. 1 829 cases were reported as chronic hepatitis B, the proportion was 39.92%. The validity cases of the information for liver puncture and the HBV surface antigen (HBsAg) transform during the recovery period in supplementary cards for all the reporting cases were 579 and 4 961, and the rate were 0.91% and 7.80%, respectively. 4 302 suspected acute cases were made confirmed diagnosis, and 1 197 cases (27.82%) were confirmed acute and 2 590 cases (60.20%) were confirmed chronic.

CONCLUSIONClinical doctors failed to make full use of the information of supplementary cards to make classification diagnose for hepatitis B. Suspected acute hepatitis B with anti-HBc IgM positive should be pay attention to follow up and further distinguish acute or chronic hepatitis B according to the HBsAg transform.
