ABSTRACT
@#<b>Objective</b> To investigate the changes of chromosome aberration and micronucleus frequencies in the peripheral blood of patients with cancer before and after treatment, and to provide a basis for clinical prevention and treatment. <b>Methods</b> We collected the physical examination data of 102 patients with cancer before and after treatment from 2016 to 2021 to analyze the changes of chromosome aberration and micronucleus frequencies in peripheral blood. <b>Results</b> Before and after treatment, there were significant differences in chromosome aberration frequency and micronucleus frequency in peripheral blood lymphocytes in patients having radiotherapy or chemoradiotherapy (all <i>P</i> < 0.05), but no significant difference was observed in either index for patients having chemotherapy (both <i>P</i> > 0.05). Before and after radiotherapy, there were significant differences in the numbers of patients with abnormal chromosome aberration frequency and those with abnormal micronucleus frequency in lymphocytes (both <i>P</i> < 0.001). Before and after chemotherapy, there was no significant difference in the number of patients with abnormal chromosome aberration frequency (<i>P</i> = 0.100) or those with abnormal micronucleus frequency (<i>P</i> = 0.110). <b>Conclusion</b> Radiotherapy can cause abnormalities in chromosome aberration and micronucleus frequencies in peripheral blood lymphocytes, which can be useful for monitoring radiotherapy injury to formulate effective emergency plans and evaluate radiation dose in each course of treatment.
ABSTRACT
Objective To analyze the clinical and CT characteristics of pancreatic metastasis to improve the correct diagnosis rate.Methods The clinical and CT data of 14 patients with pancreatic metastasis were reviewed retrospectively.Results Among the 14 patients,the primary malignancy was lung cancer in 6 cases,renal carcinoma in 3 cases,colon carcinoma in 2 cases,laryngeal cancer in 1 case,gastric cancer in 1 case and ovarian carcinoma in 1 case.Pancreatic metastases from renal carcinomas often developed a long period after initial nephrectomy and survived for a relatively long time.Abdominal CT plain scan and enhanced scan was performed in all cases.Four cases were of solitary type,9 cases were of multiple types and 1 was of diffuse type.Totally 28 lesions were found,which were usually located in the neck and body of the pancreas,the diameter of 28 pancreatic lesions was ranging from 0.5 cm to 11 cm,with a mean diameter of 2.3 cm.On CT plain scan,there were 19 hypodense lesions,7 slightly hyperdense lesions and 2 isodense lesions,5 necrotic lesions.On enhanced CT,the lesions showed moderate enhancement in 7 cases,circular enhancement in 6 cases,moderate and circular enhancement in 6 lesions,obvious enhancement in 8 lesions and no enhancement in 1 lesion.All patients had extra-pancreatic metastases,and 2 cases had peripheral vascular invasion.Conclusions Pancreatic metastases are rare,often accompanied with multiple lesions and extra-pancreatic metastases.The CT features of pancreatic metastases from renal carcinomas are slightly hyperdense and obvious enhancement; in other metastases,there are hypodense,morderate and/or circular enhancement lesions.Accurate diagnosis can be achieved by knowledge of patients' medical history.
ABSTRACT
In order to elucidate the degree of damage in 3 kinds of commonly encountered chronic rhinitis [simple, allergic and atrophic] patients, we continued our search with the method described earlier. The NMTR of 3 kinds of patients were 2.57 +/- 2.49mm/min, 1.67 +/- 1.63 and 1.33 +/- 1.49 respectively. All patients demonstrated reduction in rate, especially the atrophic rhinitis

Mucociliary ClearanceABSTRACT
In order to assess the diagnostic value of Beta-2 Microglobulin, we marked p beta -m and assessed its presence by radioimmunoassay method in 30 benign and 30 malignant ENT tumours. The results of these two groups were 2.03 +/- 0.03 micro g/ml and 1.77 +/- 0.06 micro g/ml respectively. The latter was significantly different from the former and the normal controls [2.02+0.67ug/ml] [p<0.01]. We agree that although it is not specific as a tumour marker, it can still furnish some relevant informations in the diagnosis and follow-up in malignant tumour patients
ABSTRACT
Objective To analyze the features of CT images of secondary pulmonary lymphoma. Methods The dats of totally 20 patients with secondary pulmonary lymphoma which were proven through lung puncture pathology or clinical treatment were retrospectively analyzed. There were 19 non-Hodgkin lymphoma cases and 1 Hodgkin lymphoma case. All cases received thorax CT scanning, and 13 of them had enhanced CT scanning. Results There were many patterns in our CT findings for secondary pulmonary lymphoma, mixed pattern in 9 cases, mass (nodule) in 4 cases, pneumonic-alveolar in 3 cases, bronchovascular-lymphatic in 3 cases, and miliary in 1 case. There were 13 cases accompanying with mediastinal lymphadenovarix, 5 cases with pleura invasion, 11 cases with pleural effusion, and 2 cases with pericardium involvement. Mild enrichment was found in 7 cases and obviously enrichment was seen in 1 case. Conclusion Diversity is the characteristic feature of secondary pulmonary lymphoma. Combined with other thorax findings, CT scaning can make a definite diagnosis.
ABSTRACT
The measurement of the nasal mucociliary transportation rate [MTR] is useful not only in the fundamental research but also in clinical evaluation of the patients as well .We have used the radioisotope 113m In-DTPA as the tracer combined with gamma scintigraphy in measuring this rate in 40 healthy aged persons. The mean value is 3.47mm/min. It is significantly slower than that of the adults and youths [5.71mm/min] [p<0.01]

In this communication, the values of serum CA-50 in a series of patients with benign and malignant GI diseases are reported. It was found that CA-50 was positive in 86.7% of 30 pancreatic cancer patients with an average level of 427.53U/ml, which was statistically different from that found in non-malignant control group. In this series serum CA-50 determination helped to confirm the diagnosis of pancreatic cancer in 6 cases, in which B-mode ultrasono-graphy failed to make a definite diagnosis, and in another 3 cases CT scanning was unable to disclose the tumor. The combination of CA-50, B-mode ultrasonography, and CT made definite diagnosis in 100% of all 30 pancreatic cancer patients. The author discussed the significance of CA-50 determination in the diagnosis and differential diagnosis of pancreatic cancer.
