Twenty cases of intrahepatic cholangiocellular carcinoma (IHCCC) were studied by lectin histochemistry for their glycoconjugate expression. Combined alcian blue-peroxidic acid Schiff (ABPS) staining was also made for mucins in these tissues. Results showed that epithelial cells of intrahepatic bile ducts contained varied quantity of DBA, WGA, LCA, Con A, PHA, RCAI, BLAI, SJA, SBA, PSA and UEAI receptors but no PNA receptors. Lectin receptors were present at varying rates; 100% (Con A), 95% (PSA), 90% (LCA), 95% (WGA), 30% (BSAI), 35% (DBA), 65% (PHA), 74% (PNA), 85% (RCAI), 35% (SBA), 25% (SJA) and 55% (UEAI), respectively. The positive rates in well-differentiated IHCCC were significantly higher than those in either moderately or poorly-differentiated IHCCC. The distribution of lectin receptors in IHCCC was obviously different from that in peri-carcinomatous, cirrhotic and normal liver, and also differed from that in epithelial cells of normal intrahepatic bile ducts. All larger ducts were stained by ABPS and were mainly blue colour, while only 80% of IHCCC were positive for ABPS staining. Most of them were blue, others were red or purple. The results suggest that the expression of glycoconjugates had changed after the neoplastic transformation of bile duct cells.

Using the sodium dodecyl sulfate/chloroform/phenol method, total RNA was extracted from human fetal liver tissue with a yield of 870-1060 micrograms/g of tissue; mRNA was obtained after chromatography on an oligo(dT)-cellulose column. Experimental studies demonstrated the translation of a poly(A)+ mRNA encoding proliferation stimulator of human fetal liver origin in Xenopus laevis oocytes.

This report presented fifty-eight renal cysts in 50 patients treated with percutaneous aspiration and alcohol injection. The cysts varied in size from 2.3 cm to approximately 13.5 cm in diameter, the amount of aspirated fluid varied from 5 ml to 780 ml. Forty-three of 58 renal cysts were followed from 3 months to one year. The curative effective rate was 95.3% and in 65.1%, the cystic cavity disappeared. The method technique, indication and preliminary experience were discussed.

During 1954-1981, 527 patients with cancer of the gastric cardia underwent resection. Of these, 146 underwent type I radical operation (transthoracic resection) with eight (5.5%) operative deaths; 344 underwent type II radical operation (abdominothoracic resection) with 42(12.2%) operative deaths; and 37 with Stage IV lesions underwent extended operation or palliative operation with 4(10.8%) operative deaths. Of 440 cases of Stage I-III cases that survived the operation, the 5-year survival rate was 18.5%, and the 10-year survival rate was 10.7%. For stage I cancer, the end results of type I and type II radical operations were similar. In Stage II, whether the lymph nodes were positive or negative, the end result of the type II operation was better, but without statistical significance. In Stage III cancer without lymph node metastases, the end result of the type II operation was better, but without statistical significance; in those with lymph node metastases, the type II operation was definitely better than the type I operation (P less than 0.05).

Based on the theory of three-column of spine and in combination with the findings on CT scannings, particularly the status of the spinal canal, of 47 patients sustained trauma of thoracolumbar spine, a comprehensive classification has been proposed and described in the paper. 26 patients out of the 47, who had had signs of neurological damage and spinal instability, were operated upon and their spines were stabilized with Harrington-Luque instrumentation. 14 of the patients treated operatively enjoyed, at the time of follow-up, the satisfactory result. We have been convinced that this comprehensive classification serves as a very good guidance in selection the procedure of treatment, operation or conservatism, and in predicting prognosis.
