Expression of gamma interferon (IFN-?)-like substance in adrenal pheochromocytoma was investigated with immunohistochemical technique. In 15 out of the 16 cases of adrenal pheochromocytoma positive IFN-@-like immunoreactive substance was detected in the cytoplasm of the tumor cells, whereas in adrenal tissues adjacent to adrenal tumors in 26 cases (pheochromocytoma 12, adrenal corti-col tumors 12, others 2) only two with pheochromocytoma showed positive IFN-?-like immunoreactive substance in the cytoplasm of zona reticularis cells. The results suggest that IFN-? may be a kind of antigen associated with differentiation of cell.

Objective To evaluation the Diagnosis value of single and consociation to drawing materials methods with bronchofibroscopy in pulmonary carcinoma.Methods 481 diagnosed patients with pulmonary carcinoma by bronchofibroscopy during July 2000 to July 2006 were analyzed.Four different drawing materials method including clamping,brushing,needling and rinse checking were used to diagnose.The positive rates of these four methods were compared with single and consociation to drawing materials methods.Results The positive rate of clamping,brushing,needling and rinse checking were 83.9%,70%,59.1%and 35.9%respectively,and the total positive rate was 90.2%after being united.Conclusions Bronchofibroscopy is one of the most important methods in diagnosing pulmonary carcinoma. Using multiple drawing materials methods in bronchofibroscopy can improve the accuracy rate of diagnosis of lung cancer significantly.

Objective To observe the effect of traditional Chinese medicine combined with ambroxol aerosol inhalation on patients with chronic obstructive pulmonary disease(COPD) in an acute stage. Methods 70 patients with COPD in an acute stage were randomly recruited into a control group and a treament group. The control group was treated with conventional western medical treatment and the treatment group was treated with traditional Chinese medicine combined with ambroxol aerosol inhalation based on the conventional western medical treatment Lung function (FEV1 and FVC) and clinical symptoms were observed after treatment. Results Compared with the control group, lung function (FEV1 FVC) and clinical symptoms in the treatment group were apparently improved after the treatment (P<0.05) .Conclusion Traditional Chinese medicine combined with ambroxol aerosol inhalation may improve clinical symptoms and lung function of COPD patients in an acute stage.

Objective To explore baccalaureate nursing students' perception of caring, so as to provide evidence for promoting their caring behaviors. Methods Phenomenology was the chosen methodology, 11 baccalaureate nursing students were interviewed in depth. Results Themes of caring were formed into four categories: caring behavior was reciprocal; the motives of caring included fear, concern, responsibility and obligation; knowledge, technical competency and professional helping relationship constituted caring; the confusions of caring came from many factors in clinical practice. Conclusions Baccalaureate nursing students can understand the connotation of caring accurately. To encourage their caring behaviors,clinical supervisors and managers should take all kinds of measures to maintain their faith in caring.

Objective To investigate the indications and mid-term outcomes of periacetabular osteotomy through ilioinguinal approach for developmental dysplasia of the hip (DDH) in middle-aged (40-50years old) adult patients.Methods Data of 10 adult patients who had undergone periacetabular osteotomies through ilioinguinal approach for DDH from August 2005 to February 2010 were retrospectively analyzed.There were 7 females and 3 males,aged from 40 to 47 years (average,42 years).Bilateral hips were involved in 3 patients,and unilateral hip was involved in 7 patients.Before this hospitalization,1 patient had received Chari osteotomy,and 1 had received hip-shelf procedure.According to the T(o)nnis classification,3 hips were classified as Grade 0,5 as Grade Ⅰ and 2 as Grade Ⅱ.The Shenton line was discontinuous in 6 hips.The average lateral center-edge angle was 3.50°±4.88°; the average anterior center-edge angle was 1.80°±5.07°; the average acetabular index angle was 18.20°±3.01°; the average femoral head extrusion index was 31.30％±4.37％; the average Harris hip score was 67.40±7.75.Changes of the indexes mentioned above were observed during the whole period of follow-up.Results All patients were followed up for 10 to 76 months (average,37 months).The T(o)nnis grade improved in 2 cases,from preoperative Grade Ⅰ and Grade Ⅱ to Grade 0 and Grade Ⅰ at final follow-up,respectively.At final follow-up,the Shenton line was discontinuous in 2 hips; the average lateral center-edge angle improved to 30.40°±3.31°,the average anterior center-edge angle improved to 29.50°±3.03°,the average acetabular index angle decreased to 4.50°±2.55°,the average femoral head extrusion index decreased to 9.90％±4.33％; the average Harris hip score increased to 84.10±4.07.The major complications included 3 cases of lateral femoral cutaneous nerve palsy which recovered in 4 to 6 months,and 1 case of iliac fossa hematoma which disappeared in 2 weeks.Conclusion With more strict surgery indication and more meticulous manipulation,periacetabular osteotomy through ilioinguinal approach can achieve satisfactory results in the treatment of DDH in middle-aged adults,which can increase hip joint congruence,relieve hip symptom and delay progression of osteoarthritis.

Objective To observe the effect of nursing intervention on type 2 diabetes in communities. Methods During Jul. 2007 to Jul. 2008, 256 cases with type 2 diabetes were chosen and intervened with non-medication treatment, direction for rational application of medication and management of the follow-up by community nurses. Results The awareness rates about blood presure, blood glucose, blood lipids and diabetes prevention & treatment among the patients were 47% , 43.8% , 60.7% and 91.5% . The compliance rates for medication, the treatment of non-medication and the attainment rate of self monitoring were 89%, 77.6% and 68%, respectively, and all of these results were significantly increased. Conclusion Nursing intervention on patients with Type 2 Diabetes in communities promotes the comprehensive treatment of diabetes.

Objective: Affective disorder patients can be effectively treated by electro-acupuncture methods without many side effects, but the mechanism of the treatment is not known. The object of this study was to discover whether there is change of guanine-nucleotide-binding protein (G-protein) level in platelets membrane from major depression patients before and after treatment by fluoxetine and electro-acupuncture. Methods:We utilized selective antibodies to quantitate the levels of the G-protein ? subunits in platelets membrane of 78 major depression patients (24 received fluoxetine treatment, 24 received electo-acupuncture treatment and 30 received placebo treatment) and 30 matched comparison subjects.Result:Levels of both G?i and G?q of the patient groups were higher than matched normal comparison subjects before treatment of fluoxetine and electro-acupuncture,the level of G?i and G?q did not change after the treatment of fluoxetine, electro-acupuncture and placebo. The level of G?s wasn't significantly different with matched comparison subjects.Conclusion:The levels of G?i、G?q in platelets membrane from major depression patients are higher than normal, the high levels of G?i and G?q in platelets membrane may be a trait abnormality for major depression patients, not a state abnormality for major depression.
