Objective To study the clinical value of color Doppler ultrasonography in typing tuberculous epididymitis.Methods The appearances of color Doppler ultrasound and the findings on operation were analysed in 33 patients with tuberculous epididymitis.Results Of the 33 patients,epididymis appeared as diffusely and heterogeneously enlarged lesions with increased flow in 2 cases,appeared as nodular lesions in 13 cases including nodi with echofree space in 3 cases, nodi with high-level echo patches in 3 cases, and low echo-level nodi in 7 cases. Multiple lesions in scrotum were detected in 17 cases, of whom epididymis up to 11 cases appeared as diffusely enlarged heterogeneous lesions with flow increased.The sonographic appearancs of tuberculous epididymitis could be divided into 3 types:diffusion type, nodus type and complicated type. Nodus type included 3 subtypes: purulence type, calcification type, and cheese type.The accuracy rate of ultrsound diagnosis was 87.9%.Conclusions Testis is easy to be involved when epididymitis appears as diffusion type, so surgical treatments should be early.Purulence type and complicated type need surgical treatments while calcification type does not. Antituberculous drug treatments can be tried before surgical treatments in cheese type.Sonography of urinary system is helpful for the diagnosis of asymptomatic tuberculosis in urinary system when tuberculous epididymitis is first suspected on sonography.

Objective To explore the effects of community synthetic nursing intervention on negative emotion of puerperium women.Methods Totals of 100 puerperium women were randomly divided into experimental group and control group,50 cases per group.The control group received conventional health education and home visits and experimental group received community synthetic nursing intervention.Score of anxiety scale ( SAS),depression scale (SDS),symptom assessment scale (SCL-90) and family function,before and after intervention,were compared between two groups.Results SAS score and SDS score in experimental group was (36.76 ± 10.62) and (37.46 ± 10.23) lower than (50.83 ± 10.85) and (49.78 ± 10.14) in control group,the difference was statistically significant (t =6.55,6.05;P ＜ 0.01 ).SCL-90 score of experimental group was lower than that of control group.The well family function in experimental group was 45 cases and 36 cases in control group,and the difference was statistically significant ( x2 =5.26,P ＜ 0.05 ).Conclusions Application of community synthetic nursing intervention in puerperal women,can eliminate harmful precipitating factor existing in person,family,society and decrease negative emotion of puerperal women.

BACKGROUNDThe curative effect of liver transplantation for patients with end-stage liver disease was encouraging in recent years and the 5-year patient survival rate can reach up to 70%. However, some patients might lose grafts due to a variety of reasons, including bile duct complications, vascular complications, primary non-function, graft rejection and disease recurrence etc. Liver retransplantation (re-LT) was the only available means for those patients whose initial grafts had failed, but the inferior outcomes of re-LT compared to primary liver transplantation (PLT) continue to be a major concern. This study aimed to analyze the indications for re-LT, optimal timing of re-LT, and strategies to improve the survival rate after re-LT.

METHODSFrom January 2001 to December 2006, we performed 738 liver transplants and 39 re-LT (5.3%) at our center. A retrospective analysis was performed to identify factors (indication for re-LT, preoperative score of model for end-stage liver disease (MELD), interval to re-LT from primary liver transplantation, methods of vascular and biliary reconstruction and common causes of death) associated with survival.

RESULTSMean follow-up period was 1.8 years (1 to 5 years). Patients with MELD score less than 20 were better than those whose MELD score was > 20 and MELD score > 30 (1-year survival, 80.0% versus 50.0% and 3/5). The perioperative survival rate of patients who received re-LT at an interval of more than 30 days and less than 8 days after the initial transplantation was higher than those who received retransplantation between 8 to 30 days following the first operation (88.5% and 74.3% versus 50.0%). The main causes of death were infection (60.0%), multiple organ failure (20.0%), vascular complications (10.0%) and biliary fistula (10.0%) in perioperative period. The overall patient survival rate of 1-month, 6-month and 1-year was 80.0%, 76.7% and 66.7%, respectively.

CONCLUSIONSOur study suggested the favorable results after re-LT. The analysis also showed optimal timing of operation, refined surgical techniques, individualized immunosuppressive regimen and effective prophylaxis and treatment of perioperative infection play an important role in achieving a higher survival after re-LT.

OBJECTIVETo retrospectively investigate the diagnosis and the outcome of Caroli's disease treated by surgical procedures.

METHODSThe clinical data of 68 patients with Caroli's disease treated by surgical procedures between 1996 and 2002 were reviewed, retrospectively.

RESULTSThe patients, with a M/F ratio of 1:1.35 and a mean age of 46, presented mainly with recurrent cholangitis. Of all the patients, 26 had a history of operation for cholelithiasis or cholangitis. On admission, the image investigations suggested that the lesions located at left lobe in 44 patients, right lobe in 9 patients, and whole liver in 15 patients. The coexisting cyst in common bile duct was found in 20 patients. The malignant transformation was found in 5 patients (8.8%). Hepatectomy was performed in 82.4% of patients, with a morbidity rate of 15.0% and mortality rate of 0 after the surgery. The long-term outcome of symptom-free in hepatectomy group was 90.2%, significantly higher than the 33.3% in non-hepatectomy group (P < 0.01) after a 3 to 10 years of follow-up.

CONCLUSIONSHepatectomy offers a curative procedure for local Caroli's disease, and liver transplantation is a good option for diffuse sufferers.

Objective To estimate the intangible cost and associated factors on patients with hepatitis B-related diseases, so as to explore the differences of the three elicitation techniques on the health economics-related information by trained investigators, using a structured questionnaire. WTP was employed to estimate the intangible cost while an open-ended question format, together with iterative bidding game and payment card were respectively used to elicit WTP for the hypothetical cure of hepatitis B-related diseases. A Multiple linear stepwise regression model was determined to identify those factors potentially affecting the intangible cost. Results A total of 564 subjects from 641 patients with hepatitis B-related diseases were identified for the inclusion of this study. The average annual intangible cost of patient with hepatitis B-related diseases was 54 320.4 Yuan (Ren Minbi).The intangible cost accounted for 53.0% of the total cost, which was much more than the proportions of the direct and indirect costs (38.5% and 8.5%, respectively). Among annual personal and the household income of the patient, proportions of intangible cost were 262.6% and 67.6% respectively,suggesting that the patients were under huge spiritual and psychological pressure. Response rate of the approach, combined open-ended questions with iterative bidding game, was the highest (76.6%) among the three elicitation formats. Considered the characteristics of data being gathered, the approach seemed to be more reasonable. Further studies were needed to examine the results yielded from other WTP elicitation formats. We also noticed that the progression of disease was associated with the increase of direct and indirect costs, but not with the intangible cost. Data from the multiple linear stepwise regression analysis indicated that the types of hospital and commercial medical insurance were significantly different in explaining the variation of the intangible cost. Conclusion Measures should be taken to reduce the intangible cost of hepatitis B-related diseases. The approach regarding the combination of open-ended questions with iterative bidding game should be recommended when carrying our further WTP studies of this kind.

OBJECTIVETo discuss the correlation between sonographic appearance of different degrees of acute unilateral testicular ischemia and histological changes of the testis after reperfusion.

METHODSThirty-two male rabbits were equally divided into a control (sham operation) group and 3 ischemia groups. Unilateral testicular ischemia models were established under the color Doppler ultrasound (CDU) observation and allocated according to different degrees of ischemia to Group A (with homogeneous echoes and slightly decreased flow signals), B (with heterogeneous echoes and obviously decreased flow signals) and C (with radial or small-shredded low echoes and absence of flow signals). Then contrast-enhanced ultrasonography (CEUS) was performed, followed by reperfusion of the ischemic testes. A month later, the histological changes of the testes were observed and the correlation of the histological changes with the sonographic and CEUS manifestations was analyzed.

RESULTSConcerning the CEUS parameters such as the arrival time (AT), reperfusion rate, time-to-peak (TTP), half descent time (DT/2) of the ischemic testes, Groups A and B showed significant differences from the control group (P < 0.05). The peak-base difference (PBD) was significant in Group B (P < 0.05) but not in A (P > 0.05), and no enhancement was seen in Group C. As for Johnson's scores obtained 1 month later, Group A exhibited no significant difference (8.70 +/- 0.39) (P > 0.05), Group B showed significant difference (6.01 +/- 0.88) (P < 0.05), and Group C extremely significant difference (3.16 +/- 1.05) (P< 0.001) from the control group (9.10 +/- 0.11).

CONCLUSIONCEUS is superior to CDU in evaluating the perfusion of testicular ischemia. Sonographic appearances of testicular ischemia are significantly correlated with histological changes of the testis after reperfusion. Ultrasonography helps to predict the spermatogenetic function of ischemic testes after reperfusion.

OBJECTIVEFor clarifying the situation of the natural infection of rodents having hemorrhagic fever with renal syndrome (HFRS) virus and to type Hantavirus (HV) using molecular technique in Shenzhen city in 2005, and offering guidance for prevention and control of HFRS.

METHODSData on the host animals was collected from the city of Shenzhen. ELISA and indirect immunofluorscent antibody(IFA) test were applied to the specific antibodies against HV in the sera of captured rats. Direct immunofluorscece assay was adopted to determine HFRS antigens and the lung tissues of the HV infected rats were inoculated into Meriones unguiculata to isolate HV. The whole viral RNA was extracted from the lung tissues of the HV infected rats and amplified the partial M fragments with RT-nested-PCR, using the HV genotype specific primers. The amplified genes were then sequenced, and subjected to genotyping and homology analysis.

RESULTS472 rodents were captured from Shenzhen in 2005. Surveillance on rats demonstrated 9.96% rats carrying HV (with a density of 8.25%) and the main host was Rattus norvegicus. In the blood samples of rats, anti-HV IgG antibodies were detectable in 56 cases by IFA, and proved to be positive in 76 cases by ELISA. We successfully isolated a HV strain designated as SZ2083 from Rattus norvegicus for the first time in Shenzhen and was identified to SEO type by RT-nested-PCR. Compared with the coding region of the M gene of HV L99 virus strain, the homologies of nucleotide among them were 97%, but the homology was 76% of the SZ2083 with HTN 76-118 virus strain.

CONCLUSIONResults showed the existence of natural epidemic areas of HFRS in Shenzhen city. Based on the results of sequencing, it is possible that the Seoul strain of HV might be the predominant serotype of virus harbored.

OBJECTIVEObstructive sleep apnea-hypopnea syndrome (OSAHS) may cause serious morbidities, such as systemic hypertension, diabetes, and cor pulmonale. However, currently no many reports on study of OSAHS in children are available. This study aimed to explore the effects of OSAHS on children's multiple systems.

METHODA total of 89 cases of children who came to the Sleep Treatment Center in the authors' hospital from March 2009 to December 2010 with snoring were tested with overnight polysomnography (PSG). They were classified into mild OSAHS group (n = 59, mean age of 5.71, SD = 2.46) and moderate to severe group (n = 30, mean age of 5.30, SD = 2.73) based on the PSG results, and 100 healthy children were selected as the control group (n = 100, mean age of 6 years, SD = 2.98). Data including height, weight, body mass index and blood pressure, peripheral blood routine, blood lipids, glucose and insulin, electrocardiogram and echocardiography were collected. Patients' adenoid face and abnormal occlusion were also recorded. Comparisons of the data were made among those groups.

RESULTMild OSAHS and moderate to severe group had significantly higher prevalence of adenoid face (23.7%, 26.7%), and abnormal occlusion (74.6%, 60.0%) than that in control group (0, 40%) (P < 0.05). There were no significant differences in terms of BMI between the OSAHS group and the control group, but the weight (kg) and height (cm) in the mild OSAHS group (23.3 ± 10.1, 114.9 ± 16.2) and moderate to severe group (21.9 ± 8.4, 110.8 ± 13.3) were lower than those of the control group (31.8 ± 10.1, 136.1 ± 15.1) (all P < 0.05). Compared with the control group, the level of HDL-C (mmol/L)and insulin (mU/L) in moderate and severe group decreased [(1.20 ± 0.30) vs. (1.40 ± 0.27), 2.79 (0.84 - 16.16) vs. 4.92 (0.76 - 16.80), P < 0.05], while the LDL-C (mmol/L) increased [(2.61 ± 0.75) vs. (2.32 ± 0.62), P < 0.05]. The red blood cell counts (× 10(12)/L) and the blood platelet counts (× 10(9)/L) in the mild OSAHS (4.93 ± 0.37, 292.92 ± 75.64) and moderate and severe OSAHS group (5.23 ± 0.22, 292.50 ± 63.05) were significantly higher in contrast to the control group (4.70 ± 0.31, 255.60 ± 69.12) (all P < 0.05), systolic blood pressure (mmHg) in mild group (98.54 ± 10.44) and moderate to severe group (99.13 ± 19.13) was significantly higher compared to control group (87.88 ± 11.37), and the heart rate (beats/min) in moderate to severe group (94.43 ± 10.64) was higher than those in control group (87.12 ± 16.20) (all P < 0.05). The mild OSAHS and moderate and severe OSAHS group had decreased right ventricular internal diameter [(14.24 ± 1.64) mm, (13.17 ± 2.07) mm ], increased main pulmonary artery diameter [(17.05 ± 3.33) mm, (16.33 ± 3.14) mm] and the thickness of right ventricular wall [(3.43 ± 0.26) mm, (3.57 ± 0.20) mm] compared to control group [ (16.10 ± 2.96) mm, (14.11 ± 2.52) mm, (3.32 ± 0.25) mm] (all P < 0.05).

CONCLUSIONOSAHS in children may be associated with craniofacial malformations, and may contribute to slow growth and development, elevated blood viscosity and blood pressure, metabolic abnormalities, and change cardiac structure.
