This Conference is a tribute to the scope and excellence of Chinese surgery, and its role in international surgery. In addition, it is a special tribute to the memory and work of Dr. Tseng Hsien-chiu (Zeng Xian-jiu), our co-spoonsor of the meeting.

The study of geriatrics has attracted many scholars both at home and abroad. In 1981, we reported a group of 703 cases of elderly gastric Diseases1. In order to study their clinical features, we collected and analyzed the data of 1 698 elderly patients (aged 60 and above) out of 25 528 cases examined by gastroscope from December 1973 to March 1986, at the First Affiliated Hospital. Analysis and discussion were also done of a group of 144 elderly inpatients with upper gastrointestinal hemorrhage during 1973-1982.

150 bone specimens obtained from 8 autopsied children with Kaschin-Beck's disease were comparatively studied radiologically and pathologically. It is found that the X-ray signs appearing serially are all changes during the repairing process or dysosteogenesis, elimination, organization and ossification of the necrotic matter in the necrosis area of the cartilage. Repair signs are mild at the early stage and marked at the late stage. After reconstruction and modeling, the pathologic changes disappear or become stable or result in deformity.

A perusal of the medical literature revealod only one case of giant nonmetallic in traocular foreign body, 15×11×7 mm, removed in China However, no mention was made of the operative result of the wounded eye in the report. Usually after removal of intraocular foriegn bodies, especially the giant ones, the eyeball becomes inevitably atrophied, thus it has to be enucleated soon after operation.

Keshan diesase is an endemic cardiomyopathy in China. A study was made of the histopathologic changes of pancreas in Keshan disease and non Keshan disease necropsies. The pancreatic septal atrophy had some pathologic characteristics, in which atrophic acini septally divided the lobules into nodules, and the islets were usually spared. In 92 cases of Keshan disease in Chuxiong district, Yunnan Province, the incidence of severe atrophy was 4.35% (40/92). A few cases of pancreatic septal atrophy were also found in the necropsies of non-Keshan disease, but almost all of such cases were only found in various heart diseases. Not a single case of severe septal atrophy was found in portal flow obstructed disease, such as in cirrhosis. The present data indicate that the septal atrophy of pancreas can hardly be explained only by congestion. It is necessary to go further into the relation among the en vironmental, geochemical and nutritional factors, acinus atrophy of pancreas and myocardial necrosis.

Zinc is closely related to children's health and growth. We selected 120 children with low serum zinc. Adopting random double-blind method, we treated two groups of children, 60 each, with sulphate zinc syrup and licorice acid zinc capsules respectively.

By acid phosphatase (ACP), 5-nucleotidase (5'N) activities and PAS reaction patterns, the classification of 31 acute lymphoblastic leukemia (ALL) cases (including 5 adult cases) were studied cytochemically. The results indicated that 16% of the cases were T-ALL, while 84% were nonTnonB-ALL. The results of monoclonal antibody method and E-rosette method were in good accordance with the cytochemical classification. The various forms of ACP activity patterns, PAS reaction, the relationship between the results of monoclonal antibody, E-rosette and cytochemical method and the practical value of ACP activity pat terns in the identification of E-rosette negative ALL are discussed.

To estimate and renal damage in hemorrhagic fever with renal syndrome (HFRS), concentrations of urine lysozyme (uLZM), serum lysozyme (sLZM) and urine immunoglobulin G (uIgG) were examined in 57 patients with HFRS. Our studies showed that elevated levels of uLZM and uIgG correlated well with the severity and duration of the acute renal failure in the patients. An increase in uLZM concentration lasted longer than that of uIgG. The sLZM levels appeared to have no relationship with the uLZM concentration. Thus, we come to the conclusion that in the patients with HFRS, both glomerurlar and tubular damage occurred in the early stages, whereas tubular injury predominated during the later course of the illness.

The 2,3-diphosphoglycerate (2,3-DPG) content of freshly drawn blood is 22.4±1.49 µM/gHb. When whole blood with ACD preservative solution is stored at 4 C for 3-4 weeks, the erythrocyte 2,3-DPG content decreases to 2.91±0.86 µM/gHb (12.96% that of fresh blood). The erythrocyte oxygen delivery capacity lowered correspondingly with the decrease in 2,3-DPG content. Extract of Radix Codonopsis pilosulae 党参 and Radix Astragali 黄芪 were added to 2,3-DPG depleted blood and stored at 37C for 4 hours. Now the 2,3-DPG content was 9.11±2.00 μM/gHb (40.67% that of fresh blood), lactic acid 5.09±0.64 mg/mgFe and P50 32-33 mmHg. Control samples without the herbals added were correspondingly 4.18±1.32 µM/gHb (18.56% that of fresh blood), 3.86±0.84 mg/mgFe and 36-38.5 mmHg. It appeared that Radix Codonopsis pilosullae and Radix Astragali can promote erythrocytc glycolysis, increase erythrocyte 2,3-DPG content and improve oxygen delivery capacity.
