1.DISTRIBUTION AND SIGNIFICANCE OF S-100 PROTEIN IN MALIGNANT MESOTHE-LIOMAS
Medical Journal of Chinese People's Liberation Army 1982;0(03):-
Immunohistological methods were used to investigate the presence of s-100 protein in 16 cases of malignant mesothelioma (MM) and 20 metastatic gastrointestinal adenocarcinoma of peritoneum. Positive staining for s-100 protein was observed in 14 of 16 MM, while it was negative in all metastatic gastrointestinal adenocarcinoma of peritoneum. Since antibodies to s-100 protein are readily available as standardised commercial products, the combined immunolocalisalion of s-100 protein should prove to be an efficient routine means of differentiating MM from difficult cases of metastatic gastrointestinal adenocarcinoma of peritoneum, in both necropsy and surgical cases.

Objective To analyze the factors affecting quality of life (QOL) in patients with stroke. Methods Eight hundred and six stroke patients were recruited by using the stratification and random sampling method, and QOL questionnaire was applied. Results It was shown that QOL was worse comparatively in stroke patients with poorer education, divorce or lose of spouse, non-free medical service, unemployment, serious deficit of nervous function, while it was indicated by the results of multiple factor analysis that QOL was influenced mainly by such factors as education background, marriage and neurological function. Conclusion In order to improve QOL of patients, we should pay more attention to the health of elders, social security system, education and medical technology.

OBJECTIVE: To study the hospital infections caused by ESBLs-producing Escherichia coli and Kalispell.METHODS: Bacterial drug resistance of 460 stains of ESBLs-producing Escherichia coli and Kalispell pneumonia and the application of antibiotics in our hospital in 2005 were analyzed retrospectively.RESULTS: The infections caused by ESBLs-producing Escherichia coli and Kalispell pneumonia were more often found in department of respiratory diseases,ICU and neurosurgery patients,which were treated empirically predominantly with levofloxacin,followed by cefoperazone/sulbactam,but were treated mostly by carbapenems,levofloxacin,cefoperazone/sulbactam after the drug susceptibility test results were obtained.The drug combination was characterized predominantly by combined use of two kinds,at most 6 kinds in combination.CONCLUSION: In most of the cases the medication for infections caused by ESBLs-producing Escherichia coli and Kalispell pneumonia is effective and reasonable.However,in a few cases the application of antibiotics is irrational and nonstandard,which should be given fully attention.

Objective To analyze the CT, especially HRCT appearance of localized organizing pneumonia. Methods The CT scans of nine patients with histologically proved localized organizing pneumonia were studied retrospectively. Results The size of the lesions in nine cases varied from 2 to 4 cm( average 2.5 cm). Eight lesions were located in the peripheral lung parenchyma near the pleural surface. The lesions were detected as round in four, anomaly in five. The margin of six lesions had inward bow indentation. Infiltrating lesions in surrounding structures were found in four cases. Conclusion The CT, especially HRCT appearance of localized organizing pneumonia shows some features that can make most of them to be differentiated from other lesions.

Atrial fibrillation (AF) is the most common arrhythmia,but its pathogenesis is still unclear.With the development of sleep medicine,obstructive sleep apnea (OSA) is found to associate with the occurrence of AF and recurrence after catheter ablation.This article reviews the pathophysiology of OSA,and relationship between OSA and the occurrence of AF,and its mechanism.It indicates that clinicians should pay close attention to the existence of OSA during diagnosis and treatment of AF.

Objective To explore the incidence, causes and management of peripheral vascular complications after cardiac catheterization Methods Cardiac catheter data and clinical data of 1?745 patients were reviewed Results One hundred and two patients (5 9%) had peripheral vascular complications, including local hematoma (77, 4 4%), pseudoaneurysm (4, 0 23%), arteriovenous fistula(2, 0 11%), femoral arterial thrombosis(2, 0 11%), femoral venous thrombosis (3, 0 17%), pulmonary thromboembolism (2, 0 11%), external hemorrhage(13, 0 74%) The mortality was 0 06% (1/1745), and the surgery repair rates 0 11% ( 2/1?745 ) Conclusion Peripheral vascular complications of cardiac catheterization is not so rare, and has a good prognosis after conservative management

Objective:To investigate the effects of the different static compressive stress on the proliferation and apoptosis of condylar chondrocytes in vitro.Methods: 0, 12, 24, 36 kPa static compressive stress were applied to the third passage of mandibular condylar chondrocytes for 1 hour respectively. The changes of proliferation and apoptosis of condylar chondrocytes were evaluated by flow cytometry analysis. Results: The index of proliferation and apoptosis of cells decreased with the magnitude value of static compressive stress except 24 kPa group. The most significant decrease of proliferative index and apoptosis index was found in 36 kPa group and 12 kPa group respectively. Conclusion: There might be some corelationships between magnitude of static compressive stress and the proliferation and apoptosis of condylar chondrocytes.

Objective To investigate the significance of modified gold nanocages ( GNCs ) in photothermal therapy and radiosensitivity enhancement for murine mammary carcinoma 4T1 cells.Methods A molecule probe, CD44-PEG-GNCs, was constructed on the basis of GNCs.Inductively coupled plasma mass spectrometry ( ICP-MS) and transmission electron microscopy ( TEM) were used to analyze Au uptake by 4T1 cells.The cell counting kit-8( CCK-8) assay was used to determine the impact of the probe on the viability of 4T1 cells.The CCK-8 assay and the Hoechst/PI double staining were used to evaluate the photothermal killing effects of near infrared laser (NIR).The colony forming assay and the Hoechst/PI double staining were used to measure the viability of 4T1 cells after irradiation with 6 MV of X-ray.Results ICP-MS and TEM showed that 4T1 cells had an uptake of a large number of GNCs, in which the number of CD44-PEG-GNCs taken up by 4T1 was 3-4 times larger than that of PEG-GNCs.The cell toxicity assay revealed that in a certain range of concentration, GNCs showed little effect on the viability of 4T1 cells, which was reduced to 81.2%in 48 hours.The CCK-8 assay, the Hoechst/PI double staining, and the colony forming assay showed that after NIR irradiation and radiotherapy, large-scale apoptosis was induced in CD44-PEG-GNCs-contained tumor cells by photothermal therapy combined with radiotherapy, which had substantially better outcomes than other groups.Conclusions The GNC-based molecular probe actively targets 4T1 cells with little cytotoxicity, indicating that it enhances the sensitivity of tumor towards photothermal therapy and radiotherapy.

Objective To investigate the clinical effect of laparoscopic surgery on gynecologic malignancies,providing information for the clinical therapy.Methods 35 patients with gynecologic malignancies treated with laparoscopic surgery were selected as the observation group.While 35 cases of abdominal surgery patients were selected as control group at the same period.The incidence of postoperative complications,survival rate and other conditions of the two groups were observed and compared.Results The operation time of laparoscopic surgery group was longer than open surgery group,no significant difference between the two groups(P > 0.05 ).Blood loss,hospital slay and recovery time of body temperature of the laparoscopic surgery group was significantly lower than open surgery group ( P <0,05).2 cases had urinary retention,1 urinary tract infection and 1 deep vein thrombosis occured in observation group; while 3 urinary retention cases,1 intestinal obstruction case,1 deep vein thrombosis case,1 abdominal wound infection case occured in control group,and the difference was significant ( P < 0.05 ).2 patients lost in each group.3-year survival rate of laparoscopic surgery group was similar with open surgery,the difference between the two groups was not statistically significant( P < 0.01 ).Conclusion Excision and pelvic lymph node dissection under laparoscopy is an effective method in treatment of gynecologic cancer,and with less trauma and faster recovery.
