Objective To explore the current status of the family function and the influential factors in the community, Methods A questionnaire survey including the general data questionnaire and APGAR scale developed by Smikstein was conducted in 94 families of three communities of Wuhan City. Results 46.8% of the surveyed family showed good function, 51. 1% showed moderate dysfunction and 2.1% in severe dysfunction. The multinomial regression revealed that education level and whether the family members had chronic diseases had influence to the family function level (P<0.05). Conclusions More than 50% of the families exist moderate or severe family dysfunction. The higher education level, the better family function; meanwhile compared with the family whose members experience chronic diseases, the family without experiencing chronic dieseases shows much better family function.

OBJECTIVETo construct a replication-defective recombinant adenovirus expressing the ORF2 (112-660aa) antigen of hepatitis E virus (HEV) and evaluate its immunization effect in BALB/c mice by mucosal inoculation.

METHODSThe HEV ORF2 gene encoding for 112-660aa was amplified from plasmid pUC-HEV and inserted into the transfer vector pTrack-CMV. The recombinant plasmid and adenoviral backbone plasmid pAdEasy-1 were co-transformed into E. coli strain BJ5183. Taking the advantage of the high efficient homologous recombination machinery presented in bacteria, the recombinant adenovirus backbone plasmid was generated in BJ5183, and then was transfected into 293 cells. Recombinant Adenoviruses were propagated in 293 cells with high titers. 8-week-old BALB/c mice were inoculated intraperitoneally and intranasally with 10(7) pfu recombinant adenovirus each on weeks 0, 3, 5, 7, 10.

RESULTSBoth groups of mice induced humoral IgG immune response with the highest titers 1:1,000 and 1:10,000 each. Only the group inoculated intranasally could induce mucosal IgA immune response.

CONCLUSIONSThe adenoviral recombinant can stimulate specific humoral and mucosal immune response in mice and is potentially to be used as a candidate vaccine for the treatment of HEV infection.

The aim of this study was to investigate the effects of ouabain and some specific signal pathway inhibitors on growth regulation in various kinds of leukemia cell lines and to explore the role of signal pathways participating in proliferation or apoptosis of leukemia cells induced by ouabain. By using MTT, the survival rates of leukemia cell lines were observed after utilizing ouabain and the specific signal pathway inhibitors. The expressions of Na(+), K(+)-ATPase alpha1 subunit of leukemia cells were evaluated by RT-PCR and Western blot. The results showed that low concentration of ouabain (10 nmol/L) could increase the survival rates of lymphocytic leukemia Jhhan cell line and megakaryocytic leukemia M07e cell line, and could up-regulate the expression of Na(+), K(+)-ATPase alpha1 subunit. Proliferation of these leukemia cells induced by ouabain could be inhibited by PP2 and PD98059 with different extents. It is concluded that Na(+), K(+)-ATPase plays an important role in signal transductions through binding to CTS (ouabain), and they can activate complex signal pathways regulating the growth of leukemia cells. The proliferation effects of cells promoted by ouabain are mediated by activation of Src kinase and ERK1/2 dependent signaling pathway.

OBJECTIVETo explore the diagnosis, treatment, and prognosis of prostatic malignant mesenchymal tumors (PMMT).

METHODSWe retrospectively analyzed the clinical and follow-up data about 20 cases of PMMT and reviewed the literature relevant to the diagnosis, treatment, and prognosis of the disease.

RESULTSBased on the results of pathology and immunohistochemistry, the 20 PMMT cases included leiomyosarcoma (n = 7), rhabdomyosarcoma (n = 5), prostatic stromal sarcoma (n = 3), chondrosarcoma (n = 1), and undifferentiated PMMT (n = 4). Twelve of the patients were treated by radical prostatectomy (3 concurrently by sigmoid colostomy and 1 by cystostomy), 2 by pelvic tumor resection following arterial embolization, 1 by total pelvic exenteration, 1 by colostomy with pelvic lymph node biopsy, and 4 by conservative therapy because of metastasis to the lung, pelvis and bone. Of the 20 patients, 9 died of systemic metastasis within 3 months after treatment, 3 died at 6, 7, and 14 months, respectively, 3 survived with tumor for 5, 11, and 12 months, respectively, 2 survived without tumor for 12 and 24 months so far, all subjected to periodic chemotherapy postoperatively, and 3 lost to follow-up.

CONCLUSIONPMMT is a tumor of high malignancy and rapid progression, for which transrectal ultrasound-guided biopsy remains the main diagnostic method. The clinical stage of the tumor is an important factor influencing its prognosis and the survival rate of the patients can be improved by early diagnosis and combined therapy dominated by radical prostatectomy.

OBJECTIVETo explore the feasibility of a dual-energy computed tomographic angiography (DECTA) protocol using test-bolus injection with reduction of contrast material (CM) dose in second generation dual-source CT system.

METHODSTotally 57 consecutive patients underwent CT angiography scan covering the cervical and cerebral arteries. CT was performed with second generation dual-source CT system. The time to peak (T) using a test-bolus injection was calculated. The patients were divided into three groups (A, B, and C) with different CM doses (40, 45, and 50 ml) and different delay time points [ (T+1) , (T+1) , and (T+2) s] . All the patients were followed by a 48 ml saline flush. Arterial enhancements were quantified by measuring attenuation values of the aortic arch, bifurcation of common carotid artery, contralateral internal jugular vein of the CM injection, superior vein cava, proximal middle cerebral artery, basilar artery, and straight sinus on source images. Visualizations of intracranial artery and ipsilateral venous effect of the CM injection were rated on a four-point grading scale on CTA images for qualitative assessment.

RESULTSAlthough the attenuation of internal jugular vein and straight sinus were significantly lower in group A than in groups B and C (P<0.05) , the attenuation of aortic arch, superior vein cava, common carotid artery, middle cerebral artery, and basilar artery vessels showed no significant differences among these three groups. The scores of the visualizations of intracranial artery and ipsilateral venous effect of the CM injection were also not significantly different among these three groups.

CONCLUSIONBased on the delay time calculated by a test-bolus injection, a reduced-dose contrast material may provide an equal degree of arterial attenuation and a lower attenuation of vein for dual-energy CTA covering the craniocervical region in second generation dual-source CT system.

OBJECTIVETo assess the quality of life in cured patients with severe acute respiratory syndrome (SARS).

METHODSOne hundred and nineteen SARS outpatients, including 64 men and 55 women, with mean age (34.1 +/- 11.4) years and average days of discharge from hospital (28.0 +/- 12.8) days, were assessed by the St George's respiratory questionnaire (SGRQ), and 72 patients with spirometry test.

RESULTSThe patients had a moderately degree physiological impairment and increased SGRQ score. Scores of all four part of SGRQ correlated significantly with diffuse capacity of the lung for carbon monoxide/pre (DLco%). The correlation coefficients between the activation, impaction, total score, and diffuse capacity of the lung for carbon monoxide/alveolar ventilation/pre (DLco/Va%) were resembled (r = 0.47-0.54, P < 0.01). There was a significant relationship between the score of SGRQ and patients age, and gender. The time leaving hospital only had a significant relationship with the symptom score of SGRQ.

CONCLUSIONSSGRQ is a sensitive tool for assessing quality of life in cured SARS patients. The cured SARS patients' quality of life decrease moderately.
