110 patients under three years of age with pneumonia were admitted to this hospital in a period from August of 1982 to March of 1983. There were 68 males and 42 females. The patients were randomly divided into Group A and Group B .The symptoms and signs, the laboratory data, and the severity and duration of the illness of the patients of both groups were similar.After admission, laboratory examinations including WBC counts, throat swab cultures and determinations of immunity function were performed and chest x-ray films were taken for all the patients. Regular treatments were given to all of them but the patients of Group A received TDP radiation in addition.After comparing the clinical courses of the two groups, the authors found that TDP could cause more rapid disappearance of cough and moist rales in the lungs, shorten the time of recovery and the whole course of hospitalization, and hasten the absorption of pulmonary infiltrations as seen from the x-ray films. Furthermore, TDP is helpful to promote the immunity function by raising many immune indices. And the rate of lymphocyte transformation was also increased. Its influence on the bringing down of the fever to normal is not very remarkable.It is concluded that TDP radiation is a simple, safe and effective treatment for pneumonia and it is suitable to be used in children.

110 cases of infantile diarrhoea were admitted to this institute in a period from Aug. 30 to Dec. 22 of 1982.The patients were randomly divided into two groups, the TDP group and the control group. The general condition and the age distribution of the patients of both groups were similar. The patients of the TDP group received only TDP radiation instead of antibiotics and those of the control group received antibiotics therapy but no TDP. Other treatments such as fluid replacement, dietary regulation, etc, were the same in two groups. Stool samples were sent for routine examination and bacterial culture and blood samples for the determinations of the electrolyte levels, CO2CP, and immunity function for all the patients right after admission as well as just before discharge. The cure rate and course of the disease were similar in two groups. However the pathogenic organisms could still be revealed in the stool of the patients of the TDP group after recovery. But the rate of lymphocyte transformation was significantly higher in the patients of TDP group.It is concluded that TDP radiation is a simple, safe and effective treatment for infantile diarrhoea but its therapeutic mechanism remains obscure.

Objective: To evaluate recent prognosis of patients with acute ST elevation myocardial infarction (STEMI) treated by primary percutaneous coronary intervention (PCI), and explore related risk factors.Methods: Clinical data of 168 STEMI patients undergoing primary PCI were retrospectively analyzed.According to occurrence of major adverse cardiovascular events (MACE) within 30d or not, they were divided into poor prognosis group (n=40) and good prognosis group (n=128).Clinical data were compared between two groups.Logistic regression analysis was used to analyze independent risk factors for MACE.Results: Incidence rate of MACE was 23.81% among the 168 STEMI patients.Logistic regression analysis indicated that age (OR=1.326, 95%CI 1.168~1.505), family history of coronary heart disease (OR=1.852, 95%CI 1.369~2.505), number of diseased vessels ≥2 (OR=1.682, 95%CI 1.382~2.047), Killip′s class Ⅲ~Ⅳ (OR=1.693, 95%CI 1.428~2.007) and onset-to-PCI time (OR=1.785, 95%CI 1.425~2.236) were the independent risk factors, P<0.01 all;TIMI grade 3 (OR=0.623, 95%CI 0.518~0.749) and tirofiban application (OR=0.452, 95%CI 0.367~0.557) were independent protective factors for MACE, P<0.01 both.Conclusion: Advanced aged, family history of coronary heart disease, number of diseased vessels ≥2, poor cardiac function and long onset-to-PCI time are independent risk factors, while TIMI grade 3 and tirofiban application are independent protective factors for MACE.

Myxomas are the most frequent, cardiac benign cardiac tumors which often present with stroke caused by tumorous orthrombotic emboli. The treatment of embolic stroke due to cardiac myxoma is still a clinical and technical challenge. A 61-year-old man who had an embolic stroke in the left middle cerebral artery was admitted to the Third Poeple′s Hospital of Huizhou. The initial National Institutes of Health Stroke Scale (NIHSS) score was 16. He received endovascular thrombectomy after intravenous recombinant tissue plasminogen activator (rt-PA) one hour after stroke onset. No intracranial hemorrhage developed. Pathological study of embolus showed a myxoma. A cardiac mass was found in the left atrium and removed surgically three weeks after stroke. Pathological study of the tumor showed a myxoma. At the one-month follow-up after excision of myxoma, the NIHSS score was 1 and the modified Rankin scale score was 0. No recurrence of embolism occurred after surgical resection. Endovascular thrombectomy after intravenous rt-PA (bridging therapy) for embolic stroke due to cardiac myxoma is safe and effective, and early resection of atrial myxoma can effectively avoid recurrence of cerebral infarction.
