Objective To compare the clinical effect of VATS and thoracotomy pulmonary wedge resection in treatment of pulmonary inflammatory pseudotumor. Methods 46 patients with pulmonary inflammatory pseudotumor were randomly divided into the observation group(24 cases) and the control group(22 cases) ,the control group were treated by thoracotomy pulmonary wedge resection and the observation group were treated by VATS wedge resection,the intraoperative blood loss,hospital stay, prognosis and complications were compared. Results All patients of two groups were cured and discharged. The intraoperative blood loss of observation group[(46. 0±12. 3 ) ml] was significantly less than the control group [(95.2 ± 18. 6) ml] ( t = 3. 19, P ＜ 0. 05 ), and the hospital stay was significantly shorter than the control group( t = 3.01,P ＜ 0. 05 ), the difference of the incidence of complications of two groups was not statistically significant( P ＞ 0. 05 ). Conclusion VATS wedge resection of pulmonary inflammatory pseudotumor had features of less bleeding and quicker healing characteristics,could be worthy of clinical application.

Objective To evaluate the effect of interventional diagnosis and therapy in gastrointestinal hemorrhage. Methods 32 patients with gastrointestinal hemmorrhage, including 12 cases of tumor and 20 cases of vascular malformation were analized retrospectively. DSA was performed in 32 cases, barium meal radiography were undertaken in 27 cases. DSA, CTA and barium meal radiography were all performed in 13 cases. Superselective embolization was performed in 10 cases with vascular malformation. Results DSA showed clearly the radiologic features all gastrointestinal hemorrhage. Coupled DSA with CTA was reliable for diagnosis of intestinal submucosa tumor. All five cases of vascular malformation underwent successful superselective embolization showing no complication and relapse during 6 month to 2 years. Conclusions Superselective DSA and CTA are valuable methods for the diagnosis of gastrointestinal hemorrhage. Interventional embolization is an effective modarity in the treatment of gastrointestinal hemorrhage.

Objective To evaluate the imaging technique of magnetic resonance tomographic angiography (MRTA) in the investigation of etiology of hemifacial spasm (HFS). Methods Multiplane MRTA imaging of facial nerve of both sides was performed in all 121 HFS patients. Among them, 23 HFS patients received MVD subsequently. Results Among the 121 HFS patients, 119 patients had one side hemifacial spasm and 2 patients had double side hemifacial spasm,among them, neurovascular compression was found in the root entry zone (REZ) of facial nerve in 116 cases by MRTA,and the sensitivity was 94 3%;among the 119 cases which had no HFS,no neurovascular compression was found in the REZ of facial nerve in 112 cases by MRTA,and the specificity was 94 1%. Among 23 patients who received one side MVD, 21 patients had results that agreed with the multiplanar MRTA views. Conclusion Multiplanar MRTA was considered to be a very useful imaging technique for the study of etiology of HFS, and it also seemed to be a very important preoperative examination for MVD.

Objective To discuss the diagnosis, treatment and following up of the cervical lesions(CIN～cervical carcinoma Ia 1) during pregnancy. Methods Fifteen pregnant women with cervical lesions were reviewed from Jan 1998～Oct 2003 in our hospital. Results Among the fifteen cases, 11 were diagnosed as CIN～ cervical carcinoma Ia 1 based on biopsy results under copolscopy. Ten of the 11 cases had copolscopy repeated every 8 weeks and delivered at term. The left one woman terminated the pregnancy in the first trimester due to carcinoma in situ (CIS) invasion to glands. Among those 10 cases who progressed to term, four were stable during pregnancy (CINⅡ,CINⅢ,CIS and cervical carcinoma Ia1, one for each) and had the same pathology postpartum as antepartum; three had CIN I during pregnancy but changed to inflammation postpartum;one had CIS involved in glands prepartumly while CINⅡ～Ⅲ postpartumly; one had CINⅢ prepartumly and progressed to CIS involved in glands confirmed after conization postpartumly. One woman was missing after delivery. Conclusions Cervical lesions (CIN～Ia 1) less likely get worse during pregnancy. Conservative management is possible if regular cytology, copolscopy and bioposy when necessary are available. Re examination is necessary within two months after birth. Routine examination for women who have no pap smear within the last one year period would be helpful in detecting cervical lesions during pregnancy.

ObjectiveTo investigate the correlation of brainstem auditory evoked potentials(BAEP) and somatic evoked potentials (SEP) with therapeutic outcome of brain stem hemorrhage patients.MethodsBAEP and SEP were detected in the early period of 25 caees with brain stem hemorrhage by evoked potential instrument,and were surveilled dynamically.ResultsThere was good prognosis in the patients whose BAEP and SEP were normal in the first time and repeated detection.Poor prognosis happened in ones whose BAEP and SEP were abnormal in the first time and repeated detection.The difference was significant between them(P＜0.05).ConclusionCombined detection and dynamic surveillance of BAEP and SEP could predict accurately the curative result of patients with brain stem hemorrhage.

Objective: To investigate the expression of PDCD5 in tissues of normal cervix, CIN Ⅰ-Ⅲ,cervical cancer and explore the relationship between PDCD5 and cervical cancer.Methods: After we defined the most fitful condition, tissues from 18 cases of normal cervix, 19 of CIN Ⅰ, 18 of CIN Ⅱ, 20 of CIN Ⅲ and 18 of cervical cancer were defined by indirect immunohistochemical technique. Positive expression rates and intensity of PDCD5 protein were investigated by observing under microscope and analyzing with computer imaging technique. The results were analyzed with one way anova. Results: The results of immunohistochemical staining showed that the percentage of strong positive cells in normal cervical tissue and CIN Ⅰ were significant higher than those of CIN Ⅱ, CIN Ⅲ and cervical cancer. On the whole of the condition of immunohistochemical staining, the expressions of PDCD5 were downregulated along the progression of cervical atypical epithelia, but that in CIN Ⅰ was upregulated.The ODs of normal cervix,CIN Ⅰ-Ⅲ,cervical cancer were 0.322,0.366,0.287,0.252,and 0.206 respectively.The intensity of each group showed obvious differences.Conclusion: We found that the expression of PDCD5 was upregulated in CIN Ⅰ and downregulated in CIN Ⅱ, CIN Ⅲ and cervical cancer. It suggests that PDCD5 is an important apoptosis regulating factor in the occurrence of cervical cancer.

Objective To explore the risk factors of hospital infection for hypertensive intracerebral hemorrhage ( HIGH). Methods 408 patients from Department of Neurology whose length of stay equaled or exceeded 72 hours and who fitted in with the criterion for the diagnosis of hospital infection were chosen as the HICH infection group while HICH patients without hospital served as the control group. The risk factors for HICH were studied by means of both single factor analysis and multifactor analysis. Results Of more than 30 possible risk factors that were studied by means of single factors analysis, more than 20 manifested marked difference (P < 0.05). Uncondition Logistic regression analysis of the more than 20 variables indicated that rise of inhalation of food resulting from indwelling, stomach tube,kinds of antibiotics used,spray inhalation and fasting blood-glucose,accidental were the risk factors of HICH infection. Conclusion HICH infection results from the synergetic action of various factors and hospital infection could be controlled and reduced by strengthening supervision.
