The incidence and predisposing factors of neonatal pneumonia were investigated in 19,571 newborn infants in two representative areas, East City District and Shunyi County of Beijing in 1982. The results showed that the incidence in the two areas were 1.33% and 1.10%, respectively. The predisposing factors of pneumonia were preterm, postterm and low birth weight. Mode of delivery, type of feeding and cold weather were also factors related to the occurrence of neonatal pneumonia.

We treated surgically 466 cases of carcinoma of the cervix. Of these, 26 were cases of carcinoma in situ, 192 of Stage I, 241 of Stage II, 5 of Stage III and 2 of Stage IV carcinoma. The 5-year survival rate was 84.8% (395/466), and the 10-year survival rate 83.5% (238/285). Surgery combined with radiation is emphasized.

This paper deals with clinical manifestations and hematological findings in 71 cases of bone marrow metastatic cancer. In all patients, the diagnosis of malignant diseases was not made until bone marrow aspiration was examined. In contrary to what was reported in the literature, in our cases metastatic cancer cells were not found more easily in bone mar row biopsy than in aspirates. We consider combination of biopsy with aspirates at multiple sites a better way for obtaining positive findings. The morphological characteristics of metastatic cancer cells and nonspecific myeloproliferative reaction to metastasis are described, and differential diagnosis between cancer cells and atypical marrow cells discussed.

In this study, hemodynamic effects of thomotoxin are investigated in 25 hypertensives by impedance cardiography. The results indicate that rhomotoxin may produce beneficial hemodynamic effects in hypertensives.

We reviewed 50 cases of gastrointestinal (GI) malignant tumors diagnosed by contrast study combined with gray-scale ultrasonography. Our purpose was to evaluate the diagnostic accuracy of combined methods. Although contrast study remains the chief method for detecting GI tumors, sonography may add information by displaying the internal structure of the neoplasm and the extent of infiltration and metastasis if present. Our sonographic examinations have supplemented the roentgen findings in one way or another indicating that ultrasonography plays an important part in the diagnosis of the GI tumors. We suggest that whenever a GI tumor is revealed by contrast study, gray-scale ultrasound be added in order to make the diagnosis more accurate.

In detection of cell mediated immunity function by LTT, EtRFT, EaRFT and PHA-skin tests in systemic lupus erythematosus, lowered T lymphocyte function was revealed. Among the tests, EaRFT and LTT were considered to be more reflective of cell mediated immunity. Humoral immunity showed elevated IgG in 48% of the cases. Antinuclear anti bodies were positive in 81.1% with an accumulated positive rate of 99.3%; antinuclear antibody titers above or equal to 1:80 were significant and occurred more frequently in active cases. The speckled type of fluorescent nuclear pattern was encountered most frequently. Peripheral, speckled-thready and homogeneous types were observed more in active cases. In patients with lupus nephritis and albuminuria, urinary antinuclear antibodies were positive in 41.7%. In lupus patients with involvement of the central nervous system, cerebral spinal fluid antinuclear anti bodies were positive in 70%. Serum anti-dsDNA antibody determined by indirect hemagglutination was positive in 29.89%. The results basically were parallel to the isotope method. Positive patients had relatively shorter duration of illness and more involvement of the kidney. Circulatory immuno-complex determined by polyethylene glycol precipitation method was elevated in 43%. By dissociation test, the main immuno-complex contents were found to be nuclear antigen and antinuclcar antibody complex. Blood CH50 and C3 were lowered.

We have treated 972 cases of central angiospastic retinopathy with acupuncture of the Xinming point since this point was discovered in 1970. This article analyzes the effects in 861 chronically affected eyes in 533 patients. The therapy was markedly effective in 66% of eyes and at least somewhat effective in 97%. According to the forms of absorption of the exudate after acupuncture, there are three ways: a. Snow-melting, the surface of the exudate was melted and became puffy and then was absorbed little by little. This series of patients mostly belonged to this form. b. Ice-cracking, slice and large exudate, besides being absorbed on the edge, might also be cracked turning into several small slices and speed up the absorption, but it was very rare for the exudate to be absorbed in this way. c. Peeling-off, the exudate peeled off from the retina drifting in vitreous body, the vision suddenly improved markedly. This form of absorption occurred occasionally. In 78% of instances the absorption of the exudate began on the temporal side of the retina, in 22% it began on the nasal side. The therapy was more effective if the patient experienced a strong needling sensation.

We collected 448 cases of chronic gastritis (421 chronic atrophic gastritis) from 15 institutes in different areas of China. A study on the dynamic changes in intestinal metaplasia (530 slides), dysplasia (146 slides) and gastric gland atrophy was made over a period of 2 to 10 years.

Fasting serum vitamin B12 levels and intestinal absorption of free and bound radioactive vitamins were studied in patients with atrophic gastritis of Types A and B seen in Shanghai. In seven cases of Type A gastritis with megaloblastic anemia, one had serum vitamin B12 level of 65 pg/ml before the administration of vitamin B12, but the rest had normal serum vitamin B12 levels because the tests were done after vitamin B12 treatment. They all had abnormal dual isotope test results for vitamin B12 malabsorption.

In 43 cases of alveolar hydatidosis caused by Echinococcus multilocularis, the chief clinical manifestation was firm, round and rough masses located on the upper right abdomen for 2 months to 7 years. Jaundice developed in 10. Casoni's intradermal test was positive in all; but indirect hemagglutination test and immunoelectrophoresis were positive in 8. Eosinophilia was always noted. Other examinations included ultrasonic exploration, roentgenography and radioisotope liver scanning. Hemihepatectomy was performed in cases that met the indications for operation. Most of the patients had palliative resection. The general condition of all these patients improved after operation.
