Objective To analyse CT and DSA appearances of intrahepatic cholangiocarcinoma,and to improve understanding of intrahepatic cholangiocarcinoma.Methods Plain and enhanced CT scanning were performed in 17 patients with intrahepatic cholangiocarcinoma pathollogically proved,6 patients(6/17) performed dynamic CT scanning,5 performed DSA examinations.Results Pre-contrast CT scanning was a single low density lesions in all patients,post-contrast CT scanning showed slightly inhomogeneous enhancement in 17 patients,3 patients(3/17) showed low density unenhancement area with margin enhancement,2 patients delayed enhancement;Intrahepatic billary delatation was found in 15 patients and was within the lesion in 10 patients(10/15);On DSA,5 patients showed enlaragement increasment and rigidity of supplying arteries and tumour stain.Conclusion CT scanning and DSA were important,investigative methods for intrahepatic cholangiocarcinoma,the billary dilatations with slightly inhomogeneous enhancement lesions is important sign in diagnosising intrahepatic cholangiocarcinoma.

Objective To analyze MSCT characteristics of septic pulmonary embolism (SPE) caused by intravenous drug and to improve diagnosis. Methods The MSCT findings of 16 patients of SPE induced by intravenous drug were analyzed retrospectively from March, 2001 to September, 2008. Results Peripheral or sub-pleural zones were commonly affected mainly within upper lung. Patchy, nodular and cavity shadows were detected respectively in 9 (56.25%), 12 (75.00%) and 8 patients (50.00%), while pulmonary cysts in 14 patients (87.50%). Six patients underwent CTPA, and pulmonary arteries filling defect was found in 2 patients. Pleural effusion and pneumothorax were also found in 10 and 3 patients, respectively, whereas miscellaneously shaped lesions were deteced in all 16 patients. Conclusion MSCT is an important method for diagnosing SPE caused by intravenous drug abuse. Pulmonary arteries filling defect is the direct sign and the cysts and nodular shadow with or without cavity in peripheral or sub-pleural pulmonary zones are characteristic findings.

OBJECTIVE: To evaluate the significance of additional 180-degree roll test (RT) in the determination of affected side in patients with horizontal semicircular canal benign paroxysmal vertigo (HSC-BPPV). METHOD: One hundred and six patients with HSC-BPPV were performed the 90 degree RT. patients whose affected side cannot be determined by 90 degree RT were performed 180 degree roll test. RESULT: The affected side was deter- mined by the 180 degree RT in 10 cases in which the lesion side cannot be determined by the 90-degree RT. CONCLUSION The affected side of HSC BPPV was able to be determined by 180 degree RT when it not possible to be determined by 90 degree RT. 180 degree RT is an effective and simple additional method.

OBJECTIVE: To investigate the correlation betwen varying degrees of non-acute tinnitus and anxiety and depression. METHOD: Seventy-seven outpatients with non-acute tinnitus as their in chief complaint were submitted to Tinnitus Handicap Inventory(THI), Self-Rating Anxiety Scale(SAS), and Self-Rating Depression Scale (SDS). RESULT: THI and its three subscales were found to have significant correlations with SAS and SDS. The group (THI ≥ 38) had more anxiety and depression than the mild (THI < 38). Significant correlations were also observed between THI, SAS and SDS in the group with THI ≥ 38, in contrast with the group of THI < 38. CONCLUSION Patients with THI ≥ 38 suffered from severe anxiety and depression than the mild. Doctors should pay more attention to these patients, especially their psychological disorders.

In this article, the Chinese Traditional Medicine and Materia Medica Subject Headings, Standards of the People's Republic of China - Classification and Codes of Diseases and Zheng of Traditional Chinese Medicine and the Chinese Terms in Traditional Chinese Medicine and Pharmacy were compared. Three standards were compared from the terminology quantity, content and classification. Each standard has its special feature. The compatibility and consistency are not strong in these standards. More authoritative traditional Chinese medicine terminology standards need to be established for the application in the clinical practice and scientific research.

Objective To investigate the dynamic changes of three types of anti-poliovirus neutralizing antibodies and anti-hepatitis A virus (HAV) IgG antibody in children who were immunized with inactivated enterovirus 71 (EV71) vaccine (human diploid cell).Methods Serum samples were collected from the subjects immunized with inactivated EV71 vaccine.Neutralizing antibodies against EV71 and poliovirus were detected by micro-cytopathic effect neutralization test.Enzyme linked immunosorbent assay (ELISA) was used to detect IgG antibody against HAV.Results The geometric mean titers (GMTs) of anti-EV71 neutralizing antibody increased to 4.85 following the first-dose injection of inactivated EV71 vaccine.A significant increase of GMTs (up to 64.37) could be observed 28 days after the second-dose vaccination.Meanwhile, results of the dynamic monitor showed that there were slight fluctuations in the neutralizing antibodies against three types of poliovirus on day 28 (28 days after the first-dose vaccination) compared with those on day 0 (before vaccination) (P<0.05);types Ⅰ and Ⅲ anti-poliovirus neutralizing antibodies on day 56 (28 days after the second-dose vaccination) remained slightly different from those on day 0 (P<0.05), but type Ⅱ anti-poliovirus neutralizing antibody on day 56 had restored to normal level (P>0.05).The level of anti-HAV IgG antibody was stable and no significant difference was found during the observation period (P>0.05).Conclusion This study shows that inactivated EV71 vaccine has no impact on anti-HAV IgG antibody in Children during the two-dose vaccination and in anti-EV71 antibody-producing period, but has slight influence on the anti-poliovirus antibodies.In general, changes in antibody profile do not affect the clinical efficacy of immune response.

OBJECTIVE: To evaluate the clinical manifestation of Mondini dysplasia with cerebrospinal fluid leakage and investigate the effect of the surgical repair through trans-horizontal semicircular canal and vestibule approach. METHOD: Four cases which were operated by the approach of trans-horizontal semicircular canal and vestibule in our hospital were analyzed retrospectively. RESULT: The leakages were all stopped by the primary surgical closure after six-month follow up. CONCLUSION Mondini dysplasia should be considered in children or teenagers with recurrent bacterial meningitis whether or not with otorhinorrhea. Pure tone audiometry and a temporal bone CT or MRI will confirm the diagnosis. A trans-horizontal semicircular canal and vestibule approach is an effective and simple way for the treatment.

The abundance of proteins in human urine is low and easily to be masked by high-abundance proteins during mass spectrometry analysis. Development of efficient and highly selective enrichment methods is therefore a prerequisite for achieving deep coverage of urine protein markers. Notably, different experimental methods would affect the urine protein enrichment efficacy and the coverage of urine proteome. In this study, ultrafiltration, nitrocellulose membrane enrichment and saturated ammonium sulfate precipitation were used to process 10 mL urine samples from five healthy volunteers and five bladder cancer patients. The urine proteins were enriched and separate by SDS-PAGE to compare the purification efficiency of different methods. Moreover, the peptide identification effects of different purification methods were analyzed by mass spectrometry to determine the best method for enriching urine protein histones. Saturated ammonium sulfate precipitation method outperformed the ultrafiltration and the nitrocellulose membrane enrichment methods in terms of the protein enrichment efficacy and quality. The interference of highly abundant albumin was reduced, whereas the amount of low-abundance protein was increased, and the sensitivity of mass spectrometry identification was increased. The saturated ammonium sulfate precipitation method may be applied for large-scale urine processing for screening clinical diagnostic markers through proteomics.
