Objective To study the clinical manifestations,diagnosis,treatments and prognosis of the pulmonary change in mixed connective tissue disease(MCTD).Methods From January 1996 to June 2008,112 patients with definite MCTD in Second Affiliated Hospital of Harbin Medical University were retrospectively studied,and the clinical feature about pulmanary manifestations,echocardiography feature,radiology features and treatments were reviewed and analyzed.44 patients were followed up.Results 48(5 male)had pulmonary manifestation.The median age of onset of symptoms was 39 years and the median duration of disease was three years.The most common manifestation was pleural effusion and(or)pachynsis pleurae(21 cases,18.8%).16 patients(14.3%) had interstitial lung disease,and 8 cases(7.1%)had pulmonary hypertension.The cardinal symptom was short breath.Thirteen patients(11.6%)had dyspnea,4 cases(3.6%)had chest pain,and 4 cases(3.6%)had cough.Reductions of pulmonary function or abnormalities of ultrasonographic image were noted in 25(52.1%)of 48 patients with pulmonary involvement of MCTD who had not any complaint of respiratory symptoms.Six patients had reductions in diffusing capacity of the lung for carbon monoxide(DLCO),17 patients had pulmonary abnormality on chest X ray or CT,and two patients had pulmonary hypertension on doppler echocardiography.Conclusion Pulmonary involment of MCTD may contribute to prognosis seriously.DLCO was the most sensitive parameter.Pulmonary hypertension was the most common cause of death.

Objective: To investigate the possible association between globus pharyngeus and thyroid abnormalities. Methods: Forty six patients with globus pharyngeus and 50 non globus pharyngeus patients were investigated by using 7.5 MHz high resolution thyroid ultrasound. The micro abnormatities in 2 groups were compared. Results: The incidence of thyroid abnormalities in globus pharyngeus group was 58.9%(27/46),and it was significantly higher than that(18.0%,9/50)in non globus pharyngeus group( P

Objective To study the relationship of bladder residual urine volume and renal function and urinary tract infection in patients with benign prostatic hyperplasia(BPH). Methods Eighty-one BPH eases from September 2005 to September 2008 were studied retrospectively. All the cases were divided into group A (53 cases, the residual urine volume <60 ml), group B (18 cases, the residual urine volume 60-200 ml),and group C (10 cases, the residual urine volume 200 ml). Blood urea nitrogen(BUN), serum ereatinine (Cr) and urine bacterial culture were observed. Results The BUN and serum Cr in group A, B and C were (5.90 ± 3.01) mmol/L, (90.13 ± 25.08)μmol/L, (7.85±3.53) mmol/L, (128.36 ±30.25) μmol/L and (10.57 ± 4.01)mmol/L, (152.11 ± 36.68) μmol/L, respectively. The BUN and serum Cr in group C were higher than those in group A and B (P < 0.01 or < 0.05). And there was significant difference between group A and group B (P< 0.05). The incidence of urinary tract infection in group A ,B and C was 28.3%(15/53), 44.4%(8/18), 50.0%(5/10), respectively. There was significant difference between group A and group B, C (P < 0.05). But there was no significant difference between group B and group C (P 0.05). Eacherichia was the main bacteria in urinary tract infection. Conclusion The increase of bladder residual urine volume in patients with BPH enhances renal failure and urinary tract infection.

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.

A patient with intermittent right lumbar pain for more than one month and aggravating for one week was reported. The right laparoscopic radical nephrectomy was performed, and fibrosarcoma of the right kidney was diagnosed. The patient refused further radiotherapy or chemotherapy and was discharged on the 11th after surgery. One year after operation, the patient underwent chest CT, and subdural tumor of right lobe of liver was detected. A surgery was performed in another hospital, and liver metastasis from right renal fibrosarcoma was diagnosed. He was alive four months after operation.

Objective: To analyze the epidemiological characteristics of hepatitis A cases in China from 2004 to 2015. Methods: Data of hepatitis A were reported through national notifiable disease information reporting system, which covered the 31 provinces (Hong Kong, Macau and Taiwan excluded). The inclusion criteria was: date of illness onset was between January 1^st 2004 and December 31^st 2015, the status of reported card was confirmed, the case was classified as laboratory confirmed or clinical diagnosed, the disease was Hepatitis A. The information such as sex, date of birth, date of illness onset, place of residence was collected. The data was divided into three phases, 2004-2007, 2008-2011, 2012-2015, which represented the phase before expanded program on immunization (EPI), first 4 years after EPI, second 4 years after EPI. Results: From 2004 to 2015, there were totally 574 697 hepatitis A cases in China, the mean annual incidence was 3.62/100 000. The risk ratio of hepatitis A in 2015 was 0.23 when compared with 2004. Sichuan, Xinjiang and Yunnan contributed to 27.27% of the total cases in China. In 2012-2015, the incidence of western (3.46/100 000) region was significantly higher than that in central (1.21/100 000) and eastern (1.08/100 000) regions. From 2004-2015, number of cases in each age group declined greatly, with number of cases declining from 43 711 to 5 938 in the age group of 5-9 years, from 29 722 to 3 438 in 10-14, from 23 212 to 3 646 in 15-19. The number of cases declined from 24 079 to 10 304 in the age group of 0-4 (declined by 57.21%), but in 2012-2015, the incidence of 0-4 age group was still the highest, with 77.72% cases in Xinjiang and Sichuan. Famers, students and scattered children accounted for 69.95% of total cases, with student cases declined from 24.08% (2004-2007) to 8.67% (2012-2015). Conclusion The incidence of hepatitis A in China is decreasing year by year, the risk has been decreasing to a relatively low level. However, in western regions and children under age five, the risk is still high. Precision intervention is needed for further prevention and control of hepatitis A.

Objective: To review the consistency of diagnosis and reporting of hepatitis B (HB) patient in non-surveillance hospitals in three provinces and analyze the influencing factors. Methods: In 2016, using typical survey methods, we carried out a hospital-based pilot study in three provinces: Fujian, Hainan and Gansu. In each province, we chose two hospitals with grade 3 and grade 2 respectively in each province, using the following criteria: (1) in 2015, the hospital reported a greater number of hepatitis B cases compared the hospital-based provincial mean; (2) the hospital had an advanced laboratory information system (LIS) with access to HBsAg test results; (3) the hospital had an electronic hospital information system (HIS) which linked to the LIS via the inpatient medical record number; (4) general hospital; (5) non-surveillance hospitals for hepatitis B. Using national notifiable infectious disease reporting system (NNDRS), we chose all HB patients who were reported by the investigated hospitals in 2015, and we linked NNDRS HBV case-reports with patient-data from hospital information systems (HIS) to review the diagnosis, and then to compare the consistency of reviewed diagnosis and NNDRS report diagnosis, which we made a descriptive analysis. We used multivariable logistic regression to examine factors associated with misclassification of case-reports to NNDRS. Results: We found the NNDRS report accuracy was 47.11% (669) among 1 420 eligible inpatient hepatitis B inpatients. Of the 352 reported acute HBV cases, 6.53% (23) were consistent with our medical record review, the accuracy rate for level 2 hospitals and level 3 hospitals was 9.42% (21) and 1.55% (2), respectively. Of the1 068 reported chronic HBV cases, 60.49% (646) were consistent with our medical record review, the accuracy rate for level 2 hospitals and level 3 hospitals was 57.92% (106) and 60.02% (540), respectively. Compared to primary diagnosis of HB patients, the OR(95%CI) for mis-report was 29.36 (19.21-44.76) in non-primary diagnosis of HB patients. Compared to Fujian Province, the mis-report risk was higher in Hainan province and Gansu Province, with the values of OR (95%CI) being 2.33 (1.58-3.44) and 20.38 (11.29-36.78), respectively; compared to level 3 hospitals, the OR (95%CI) for mis-report was 2.38 (1.66-3.42) for level 2 hospitals; compared to HB related wards, the OR (95%CI) for mis-report was 1.45 (1.04-2.01) in non-HB-related wards. Conclusion In some non-surveillance areas of China, the consistency between hepatitis B diagnosed in hospital and reported in NNDRS was low. Factors affecting the accuracy of HB surveillance data in NNDRS were level 2 hospitals, non-liver disease departments and nonprimary diagnosis of HB.

Objective: To analyze the changing epidemiological characteristics of hepatitis E cases in China, in order to promote in preventing and controlling hepatitis E. Methods: Data of hepatitis E and outbreaks reported through national notifiable diseases reporting system were analyzed from 2004 to 2017, but data of Hongkong, Macau and Taiwan were not included. Data of hepatitis E were divided into three phases as 2004-2007, 2008-2011 and 2012-2017, representing eight years before, four years before and years after the postmarketing of hepatitis E vaccine. Linear regression was used for analyzing the trend of hepatitis E, improved muster method was used for analyzing the seasonal intensity. Results: From 2004 to 2017, 329 519 hepatitis E cases were reported and the annual incidence were increasing from 1.27/100 000 to 2.10/100 000 (t=6.87, P<0.001). The concentrations of hepatitis E during 2004-2007, 2008-2011 and 2012-2017 were 17.43, 16.06, 11.17, respectively, with low seasonal intensity. Number of cases reported by Jiangsu, Guangdong and Zhejiang accounted for 31.54% of national cases. The incidence were lower in central (1.45/100 000) and western (1.11/100 000) region than that in eastern region (2.67/100 000), but were increasing continuously. There was an increasing trend of incidence with growing ages (t=7.85, P<0.001). The incidence was higher than 2/100 000 among cases aged ≥40, and was the highest (5.22/100 000) in the age group of 65-69 years old. Farmers, retired persons, houseworkers and unemployees accounted for 67.46% of total cases. A total of 7 outbreaks were reported, among which 3 were in nursing homes. Conclusion The incidence of hepatitis E in central and western regions were increasing continuously and the surveillance should be strengthened. There was higher risk among middle-aged population, farmers and nursing homes, so strategy for immunization among those population was in great need.

Objective To analyze the duplicated reporting of hepatitis B in the national notifiable communicable disease report system (NNDRS) in China during 2011-2013.Methods The data of hepatitis B reported from January 1,2011 to December 31,2013 were collected from NNDRS,the duplicated reporting were searched with software SAS 9.1.3 according to the cases' ID number,name,gender,birth data and current address code.Results During 2011-2013,a total of 3 389 374 hepatitis B cases were reported through NNDRS,but the duplicated reporting rate was 7.35％ (249 047).According to 6 protocols,the duplicated reporting rate ranged from 0.88％ to 6.38％.If using the data in 2011 as the baseline,the duplicated reporting rate in the three years was 2.91％,8.11％ and 11.72％,respectively.In the duplicated repeating,33.04％ (71 709) occurred in the same year,and 66.96％ (145 329) occurred in other year.Without the duplicated repeating,the hepatitis B incidence in Xinjiang and Qinghai provinces in 2013 could decreased by 30.80/100 000 and 26.26/ 100 000,respectively.Conclusions The analysis indicated that the duplicated repeating rate of hepatitis B was 7.36％ in NNDRS during 2011-2013,and the duplicated reporting mainly occurred in other years.The duplicated reporting of hepatitis B in NNDRS had greatly affected the accuracy of surveillance data in some provinces,such as Xinjiang and Qinghai.
