Objective To evaluate the application value of bronchofibroscope in severe pulmonary infection.Methods 60-severe pulmonary infections were diagnosed.They were divided into two groups by random digits table.The control group were treated with conventional therapy (include:antibiotic therapy,eliminate sputum、nutritional support,and so on).The observation group were treated with not only conventional therapy but also bronchial lavage and antibiotic therapy by bronchoscope.Indicatrix and curative effect of clinical were analyzed by statistics-software.Results After treatments,The time of hemogram recoved (11.50 ± 4.31) days,and the time of Clinical symptom dispersal(12.31 ± 2.30)days and the time of fever(7.02 ± 2.23)days in the observation group were all shorter than those of control group [(16.11 ± 5.21) days,(20.09 ± 5.19) days,(11.04 ± 3.31) days].All comparisons were statistical significance(t =5.03,6.87,6.22,all P ＜ 0.05).The total effective rate was 88.5％ in the observation group,whcih was efficienter than that of the control group (62.5 ％) (x2 =4.36,P ＜ 0.05).Conclusion It is effectively to use a bronchial lavage and antibiotic therapy treated severe pulmonary infections by bronchoscope.

An unusual case of primary cutaneous anaplastic large cell lymphoma induced by influenza vaccination is reported.A 79-year-old man developed an erythematous nodule at the injection site on the upper left arm 2 months after vaccination against influenza A virus,which gradually grew and ulcerated.Pathological examination of the lesion revealed epidermal infiltrate of lymphocytes and numerous clumps of densely distributed lymphocytes with lightly stained cytoplasm,nuclear atypia and karyokinesis.Immunohistochemistry showed that the tumor cells stained positive for CD3 (90％),CD5 (90％),LCA (90％),CD30 (90％),CD10 (a few),Ki-67 (80％),but negative for CD20,CD56,cytokeratin 1-3,epithelial membrane antigen,synaptophysin,and anaplastic lymphoma kinase.The patient was diagnosed with primary cutaneous anaplastic large cell lymphoma at the injection site following vaccination against influenza A virus.

Objective To study the influence of excessive magnesium and/or deficient calcium intake on the bone mass of ovariectomized rats. Methods Three-month-old ovariectomized rats were fed with different types of drinking water: Interaction group was fed with deficient-Ca and excessive-Mg water: Ca 5 mg/L, Mg 60 mg/L; Excessive-Mg group was Ca 60 mg/L, Mg 60 mg/L; Deficient-Ca group was Ca 5 mg/L, Mg 30 mg/L; Normal group was Ca 60 mg/L, Mg 30 mg/L. After 3 months of treatment, the left femur was measured with the length and weight, then the content of Ca and Mg were determined, right femur was X-rayed, and right tibia was taken for the pathological examination. Results Calcium deficiency in water caused significant changes in all of the bone mass indexes, magnesium excess in water showed a tendency of Ca decreasing and Mg increasing in the bone. It was easily distinguish the difference in bone mineral and bone microstructure by X-ray and pathological examination: control group was the best, then was Mg excess group, Ca deficiency group was inferior, and the interaction group was the worst. Conclusion Calcium deficiency is one of the major reasons of osteoporosis, while the excessive intake of magnesium may not only disturb the bone metabolism but also aggravate the adverse effect of Ca deficiency on bone mineral and bone health.

One hundred and fifty-seven cases of Graves' disease were divided into three groups according to their clinical features and thyroid functions: Group A, untreated; group B, treated but uncontrolled or relapsed; group C, treated and remitted. The positive rates of TSH receptor antibody (TRAb), anti-tnyroglobulin antibody (TgAb), anti-microsomal antibody (TmAb), anti-DNA antibody and anti-nuclear antibody (ANA) were 91.2, 79.4, 79.4, 70.6 and 23.5% respectively in group A. The positive rate of TRAb and TBII were significantly different between group C and group A or B (both P

Objective To study the lipid regulatory effects of mannose ester and its effects on serum oxidized low density lipoprotein(OX-LDL),C-reactive protein(CRP)in patiends with coronary heart disease(CHD)complicated with hyperlipidemia.Methods Seventy-six CHD patients with hyperlipidemia were treated with mannose ester at a dose of 0.1g orally,three times a day for 2 successive months.Levels of blood lipids,OX-LDL,CRP at the time of entry,first month,second month of the therapeutic course were observed.Results Mannose ester could reduce the serum levels of total cholesterol,LDL-C 1 month after medication and the effect was further elevated after 2 months.Meanwhile its effects in lowering triglycerides and increasing high density lipoprotein were observed after 2 months administration.Mannose ester could also significantly lower the serum OX-LDL,CRP after 2 months administration.Conclusion Mannose ester has good regulatory effect on blood lipids,and decreases OX-LDL,CRP.Mannose ester can protect vascular endothelial cells and inhibit the development of inflammation in coronary plaque.Therefore,it can improve the prognosis of CHD patients.

Objective To explore the role of PI3K/AKT signaling pathway in total hepatic ischemia-reperfusion(I/R)-induced lung injury in rats.Methods This study was divided into 2 sub-projects.(1)36 rats were killed respectively at preischemia and after reperfusion,the lung tissue was then sampled.(2)12 rats were randomly divided into Wortmannin group and model control group. AKT,p-AKT protein expression,apoptotic cells and PCNA protein expression were tested respectively by Western blot,TUNEL and immunohistochemistry analysis.Results(1)Compared with that in preiscemia group,after I/R the apoptotic index (AI)was increased,the p-AKT/AKT ratio and PCNA-positive index showed bidirectional changes,and the histological changes were well identified.(2)p-AKT/AKT ratio showed a positive correlation with PCNA-positive index and a negative correlation with AI.(3)Compared with control group,the p-AKT/AKT ratio and PCNA-positive index were lower,histological changes was more significant and AI was higher in Wortmannin group. Conclusion PI3K/AKT signaling pathway had protective effect on lung injury induced by hepatic I/R,which was potentially mediated by anti-apoptosis and promoting proliferation.

Objective To detect the serum estrogen level in women with involution al depression (ID) and to study the effect of estrogen on the occurrence of ID. Methods Serum estrogen levels at 7:00 am were detec ted by r adioimmunoassay in 40 normal menopausal women (Group A) and 49 cases of ID (Grou p B), and compared with those of 36 cases previously detected. Results Estro gen level was much lower in Group B than Group A (P 0.05 ). Co nclusion The occurrence of ID in menopausal women may be related to t he decrease of estrogen level, but the specific correlation of the above two has not been proved yet.

Objective To evaluate the effectiveness of uterine arterial embolization (UAE) in the management of uterine fibroids (UF) and adenomyoma. Methods The UAE was carried out in 22 cases of UF and 2 cases of adenomyoma, including bilateral UAE in 23 cases and unilateral UAE in 1 case, by using polyvinyl alcohol (PVA) particles as embolic materials. Results The success rate of UAE in the study was 95 8% (23/24). No serious complications occurred. The uterine and UF volume decreased remarkably in size 6 months after the treatment ( t =2 391 and 3 990, respectively; P =0 022 and 0.000, respectively). In the patient who underwent unilateral UAE, the UF gradually increased in size and a hysterectomy was required. The 2 patients with adenomyoma experienced relief with this treatment but had a recurrence 4 months after the surgery. Conclusions UAE is a safe and effective method in the management of UF but its long-term effects remains a question to be answered through further observations . The efficacy of treatment of this method for adenomyoma is not apparent.
