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 radionuclide imaging and routine CT in diagnosing hepatic focal nodular hyperplasia (FNH) and the combined diagnostic value of the two modalities. Methods Thirty-two patients with hepatic FNH were retrospectively studied. All patients underwent routine CT scan. Twenty-four patients were examined by 99Tcm-sulfur colloid (SC) hepatic planar scintigraphy and SPECT/CT imaging, and then patients who had abnormal foci underwent 99Tcm-diethyl iminodiacetic acid (EHIDA) triple-phase hepatobiliary imaging. x2 -test of four-table or Fisher exact probabilities in 2 × 2 table was applied for statistical analysis. Results Of all 32 patients pathologically diagnosed as FNH with single solitary nodule, 25 were classified as classic type and the rest 7 as non-classic type. Although routine CT found all hepatic lesions, only 15 cases were diagnosed pathologically as FNH classic type but the rest were either misdiagnosed or left as indeterminate. On radionuclide imaging (hepatic colloid scintigraphy plus triple-phase hepatobiliary images), 11 patients with big foci (with maximal diameter ＞3 cm) out of 24 patients were correctly diagnosed as FNH, with 7 diagnosed as classic type FNH and 4 as non-classic. Other 13 patients were either misdiagnosed or simply missed. The diagnosing rates of routine CT and radionuclide imaging were60.0% (15/25) and 38.9% (7/18) for FNH classic type, 0/7 and 4/6 for non-classic type,50.0% (10/20) and 73.3% (11/15) for big foci, 41.7% (5/12) and 0/9 forsmall foci (with maximal diameter≤3 cm), respectively. The total diagnosing rate of radionuclide imaging combined with routine CT was significantly higher than that of routine CT or radionuclide imaging alone ( x2 = 4. 48, P ＜ 0. 05;x2 =4.27, P ＜0.05 ). Conclusion Radionuclide imaging in combination with routine CT may improve the diagnostic accuracy for hepatic FNH patients.

OBJECTIVE: To investigate the psychological statuses of Chinese adults with moderate-to-severe persistent allergic rhinitis, and evaluate the effects of nasal symptoms on their psychological statuseses. METHOD: The Symptom Checklist-90 (SCL-90) or self-reporting Inventory was employed to analyze the psychological statuses of 539 adults with moderate-to-severe persistent allergic rhinitis. RESULT: The SCL-90 scores of the adults with moderate-to-severe persistent allergic rhinitis were statistically higher than those of non-allergic adults in terms of somatization, depression, anxiety and hostility. No statistical discrepancies existed in gender or age. The course of disease contributed to somatization and compulsion. The effects of nasal symptoms included two aspects: nasal obstruction had a conspicuous impact on somatization, compulsion, interpersonal sensitivity, depression, anxiety and psychosis, while nasal itching contributed to somatization, depression and anxiety. CONCLUSION The psychological statuses of adults with moderate-to-severe persistent allergic rhinitis is evidently worse than that of non-allergic adults. Symptoms such as nasal obstruction and itching had an obvious impact on outpatients' psychological statuses.

Objective: To explore the effect of vaginal micro-environment alterations and HPV16 infection and their interaction in the progression of cervical intraepithelial neoplasia. Methods: The participants of this study came from the cervical lesions study cohort in Shanxi province, including 623 women with normal cervical (NC), 303 patients with pathogenically diagnosed low-grade cervical intraepithelial neoplasia (CINⅠ) and 93 patients with pathogenically diagnosed high-grade cervical intraepithelial neoplasia (CINⅡ/Ⅲ). The data of the demographic characteristics of the study subjects and factors related to cervical intraepithelial neoplasia were collected, and HPV16 infection were detected by using flow-through hybridization technology and H(2)O(2), β-glucuronidase, clotting enzyme, neuraminidase and leucocyte esterase in vaginal secretions were detected by using the combined detection kit of aerobic vaginitis and bacterial vaginosis. pH value and vaginal cleanliness were also detected at the same time. The database was established and analyzed by SPSS statistical software (version 22.0). Results: The HPV16 infection rate (trend χ(2)=55.45, P<0.001) and the abnormal rates of H(2)O(2) (trend χ(2)=26.19, P<0.001), pH (trend χ(2)=5.06, P=0.024), vaginal cleanliness (trend χ(2)=19.55, P<0.001), β-glucuronidase (trend χ(2)=17.52, P<0.001) and neuraminidase (trend χ(2)=14.90, P<0.001) increased gradually along with the severity of cervical intraepithelial neoplasia, but the abnormal rates of clotting enzyme and leucocyte esterase showed no same trend. The results of GMDR model analysis showed that there was interaction between HPV16 infection and abnormalities of H(2)O(2), β-glucuronidase, clotting enzyme and neuraminidase in CINⅠ group, and the interaction between HPV16 infection and the abnormalities of vaginal cleanliness, H(2)O(2), β-glucuronidase and neuraminidase in CIN Ⅱ/Ⅲ group. Conclusion: Our findings indicated that the vaginal micro-environment alterations and HPV16 infection could increase the risk of cervical intraepithelial neoplasia, and they might have an important synergistic effect in the progression of cervical intraepithelial neoplasia.

INTRODUCTIONMeasles, mumps and rubella (MMR) are viral infections causing significant mortality and morbidity for which effective and safe vaccines are available. The safety, reactogenicity and immunogenicity of a combined MMR vaccine when administered to healthy Singaporean children were evaluated in this study.

MATERIALS AND METHODSA total of 150 children aged 12 to 18 months were vaccinated in this open, single-group, single-centre study [209762/147]. Solicited local and general symptoms reported within 4 days of vaccination and fever, parotid/salivary gland swelling and signs of meningism in the 43 days following vaccination were recorded using diary cards. Serious adverse events occurring during the study period were monitored. Immunogenicity was assessed at 42 days post-vaccination.

RESULTSRedness (8.7%) and pain (7.2%) at injection site were the most commonly reported solicited local symptoms during the 4-day follow-up period after vaccination. Percentage of subjects reporting drowsiness, irritability and loss of appetite during the 4-day follow-up after vaccination was 7.2%, 8% and 7.2%, respectively. None of the solicited symptoms reported during the 4-day follow-up period was of grade "3" intensity. Fever (42.8%) was the most commonly reported solicited general symptom, with 5.1% of the children reporting fever >39.0 degrees C (axillary). No serious adverse events considered to be related to vaccination were reported. Seroconversion rates were 100% for measles and rubella antibodies and 98.1% for mumps antibodies.

CONCLUSIONSGlaxoSmithKline Biologicals' MMR vaccine was shown to be well tolerated and highly immunogenic when used in Singaporean children 12 to 18 months of age.
