RESUMO

Objective To further improve the awareness of the clinical feature of acute fibrinous and organizing pneumonia (AFOP).Methods One case of AFOP treated in our department was described in details.The relevant cases were searched in Wanfang database using key words acute fibrinous and organizing pneumonia [in Chinese].Results Four reports containing 9 cases were identified from published literature.A total of 10 cases (including this one) were analyzed.The patients included 7 males and 3 females (43 to 78 years of age).Eight patients presented with cough.Chest tightness and dyspnea were reported in 8 cases,and fever in 9 cases.Velcro crackles were heard in 4 patients.Laboratory tests showed WBC increased in 2 cases,increased neutrophil count in 6 cases,elevated C-reactive protein in 9 cases,and faster erythrocyte sedimentation rate in 8 cases.The partial oxygen pressure (PO2) ranged from 54 mmHg to 69 mmHg.Chest CT scan showed unilateral lesions in 3 cases and bilateral lesions in 7 cases initially.The main CT findings were patchy,consolidation and ground-glass opacities,sometimes associated with air bronchogram.The diagnosis was confirmed by lung biopsy in all the 10 cases.Bronchoscopy biopsy was conducted in 6 cases,and percutaneous lung biopsy in 3 cases.One patient received both bronchoscopy biopsy and percutaneous lung biopsy.Methylprednisolone was used in all cases.No patient received mechanical ventilation.One patient died.Conclusions AFOP is a new type of interstitial lung disease,the etiology of which is unknown.AFOP often occurs in middle-and old-aged patients.AFOP is easily misdiagnosed due to its unspecific clinical manifestations,which are similar to common pneumonia.The confirmation of AFOP diagnosis depends on pathological biopsy.Corticosteroids treatment is appropriate,but the dosage,duration,and long term effect of corticosteroids are not established.

RESUMO

Purpose To analyze retrospectively the clinicopahological characteristics and immuophenotype in 120 cases of pulmonary selerosing hemangioma ( PSH) . Methods Data of 120 cases of PSH were collected and reviewed, including gross features and frozen diagnosis, histopathological features, morphology in HE and immunohistochemical characteristics of tumor cells. Results PSH pres-ents a well-circumscribed mass with a sense of expansion after cutting, which showed a solid, grey to tan-yellow surface with foci of haemorrhage. Two kinds of tumor cells and four typical patterns with mixed forms, are often shown under light microscope (92/120, 76. 67%). Focal accumulation of histocytes and scattered mast cells were noted in some cases (83/120, 69. 17%). Both surface cells and round cells were TTF-1 and EMA positive. Surface cells expressed SP-A, CK and NapsinA. Round cells expressed vimentin. Conclusion Gross features and typical“two cell types, four patterns” contribute to PSH diagnosis. Meanwhile, foal accumulation of foam histocytes and scattered mast cells show a clue to PSH diagnosis and differential diagnosis.

RESUMO

Objective To investigate the correlation between age and the prognosis of thrombolytic therapy in acute ischemic stroke (AIS).Methods One hundred and fourteen patients with AIS were divided into ≤60 years group,61-70 years group and ≥71 years group according to age.Thrombolysis and post-thrombolysis treatment was done in accordance with 2010 version of Chinese Acute Ischemic Stroke Treatment Guidelines standard.The United States National Institutes of Health Stroke Scale (NIHSS) score was done in patient immediately after treatment,24 h after thrombolysis and 7 d after thrombolysis,and modified Rankin scale (mRS) score was assessed 3 months after thrombolysis The spontaneous intracranial hemorrhage (sICH) and the death of 2 weeks was recorded.Results ≤ 60 years group had 22 males and 10 females;61-70 years group had 26 males and 10 females; ≥71 years group had 20 males and 26 females.In ≥ 71 years group,women accounted for 56.52% (26/46),which was higher than that in the other 2 groups,and there was significant difference (x2 =0.685,P =0.015).The NIHSS score immediately after treatment,24 h after thrombolysis and 7 d after thrombolysis among 3 groups had no significant difference (P > 0.05).The mRS score at the 3 months after thrombolysis among 3 groups was (1 ± 3),(2 ± 5) and (2 ± 3) scores,respectively,and there was significant difference(P =0.040).Mortality and incidence of sICH in 2 weeks also had significant difference (P =0.049,0.017).Conclusions Despite the differences in the mortality and incidence of sICE among different ages,thrombolytic therapy with recombinant tissue-type plasminogen activator can significantly improve the neurological deficit after 3 months in AIS patients of different ages.

RESUMO

Salmonella Typhi capsular polysaccharide vaccines were encapsulated in the Micro-particles made from polyethylene glycol-poly-DL-lactide (PELA). BALB/c mouse were divided into three groups with 20 mice in each. Mouse were immunized respectively with controlled release microencapsulated Salmonella Typhi capsular polysaccharide vaccines and Salmonella Typhi capsular polysaccharide vaccines by oral and subcutaneous administration. The mice blood and salvia were collected at the 2nd, 4th and 8th weeks respectively for the titrating of IgG and sIgA antibodies by RIA. At the 8th week, live typhoid bacteria were injected into the immunized mice for the calculation of the rate of immunization protection. The IgG titers of the controlled release microencapsulated Salmonella Typhi capsular polysaccharide vaccines group were higher than those of the other groups(P < 0.05). The IgA titers of the low groups of controlled release microencapsulated Salmonella Typhi capsular polysaccharide vaccines (oral and subcutaneous) were higher than those of the group of Salmonella Typhi capsular polysaccharide vaccines (P < 0.05). The immunization protection rates of the three groups were 40%, 100% and 60% respectively. The controlled release microencapsulated Salmonella Typhi capsular polysaccharide vaccines possess the advantages of releasing slowly in vivo and persisting long time immunogenicity.
