Patients with thyrotoxicosis had a normal circadian rhythm of ACTH and F,but the level of serum F was lower than controls due to excessive degradation.The responsiveness of ACTH to dexamet-hasone suppression or insulin hypoglycemic stimulation was normal.Whereas the circadian secretion of ACTH and F was also normal in patients with primary hypothyroidism,and the concentration of F was inreased with normal ACTH level.There were stunted responses of ACTH to suppressing and stimulating tests,which were thought to be due to the fact that the corticotropes were impaired by hypertrophy or hyperplasia of thyrotropes in primary hypothyroidism.

Fifty cases of primary nephrotic syndrome were studied. There were 40 cases of [type I and 10 cases of type I, all confirmed by renal biopsy. Among them, 17 cases (34%) were mesangial prolife-rativc glomerulonephritis, 12 cases (24%) membranoproliferative glomerulonephritis, 9 cases (18%) proliferative endocapillary glomerulonephritis, 3 cases (6%) membranous nephropathy, 3 cases (6%) minimal change nephrosis, and 6 cases (12%) focal sclerosed glomerulonephritis. 4 to 6-weeks therapy with prednisone, cyclophosphamide and heparin ("triplex therapy") witnessed disappearance of protein-uria in 22 cases, and 44% of the patients showed marked improvement. The total effective rate was 94%. All patients except those with focal sclerosed glomerulonephritis showed favorable response to the treatment. The difference in effectiveness seemed to be related to types and degree of immune injury of the renal pathology.

25 patients with endoscopy confirmed active duodenal ulcer were treated with Xi Lei San or ci-metidine. Biopsy specimens were taken before and 3 weeks after treatment. Specimens were stained separately with HE, AB (pH2.5), PAS, and AB(pH2.5)/PAS. According to the morphological characteristics, the epithelium was divided into intestinal, gastric and transitional types. The percentage of the length and density of cells of all types were measured. The results were obtained as follows: during early phase of healing (3 weeks), goblet cells recovered most markedly in the epithelium close to the lesion. Transitional epithelium could relatively easily be observed.The Xi Lei San and cimetidine produced similar morphological changes. Endoscopically, even after the ulcer was healed, gastric and transitional epithelial cells could still be seen. Hypoplasia was observed in most of epithelial villi.

In our laboratory, we have determined the liver specific membrane lipoprotein (LSp) antigen level in the circulating blood of the patients with viral hepatitis, SLE, and chronic renal disease by means of ELISA double sandwich method, using anti-LSp McAb of own production as the reagent. The corela-tion of LSp with the changes in HBeAg, SGPT, anti-LSpAb in the paitents' blood has also been studied. LSp was negative in the serum of normal persons, and the LSp positive rate among the patients with hepatic cell damage (autoimmune or viral hepatitis) was 48.2~70.0%. Lower positive rate (10~22.2%) was found in the patients with SLE (skin type), chronic renal disease and non-symptomatic HBsAg carriers. The difference was significant (P

Erythrocytes were frozen with DMSO of different concentrations (not over 20%) as a cryoprotec-tive agent in freezers of different temperatures.The rate of temperature drop was not controlled. Of the erythrocytes actually frozen, the average recovery rate after thawing was 91.3 per cent (range 87.5~ 95%). The average survival rate of erythrocytes stored at -20℃, -30℃, or -80℃ for up to eight months was 90.9 per cent (range 88.2~ 94.5). As compared with glycerol, which is in common use internationally, DMSO seems to be a better cryoprotective agent.

In recent years, we have tried transfusion of large numbers of granulocytes in the patients withsevere infection due to gram-negative bacteria or the patients treated with various types of antibioticswithout effect. The results were quite satisfactory. We know from experience that the curative effectis related to the number of the granulocytes transfused. Only by increasing it to 6-8?109 or 6-8?1016 the curative effect can be achieved.

From Nov 1980 to Dec 1983, severed distal segments of fingers were successfully replanted by the aid of surgical microscope in 8 children. The age ranged from 31 months to 12 years. 6 fingers were completely amputated and 2 were incompletely amputated. The level of amputation was situated from distal 1/3 of middle phalanx to the distal inlerphalangeal joints. 46 fresh specimens of fingers were dissected under microscope, and regional anatomy of blood vessels and nerves of distal segment of finger were carefully studied and their calibers measured, providing a useful knowledge for replantation. It was emphasized that meticulous and accurate anastomosis of tiny arteries, and veins with diameters ranging from 0.2 to 0.3mm was the key to success o replantation. Indications for digital replantation, careful debridement under operation microscope, and postoperative management were discussed.

61 cases of chronic granulocytic leukemia were reviewed in this paper. Based on the results, the following features are suggested as the diagnostic criteria for early acute transformation: (1) fever of unknown cause, (2) bone and joint pain, (3) a fall in hemoglobin, marked increase or decrease of the number of WBC's and platelets, (4) myeloblasts and promyelocytes exceed 5% in peripheral blood and 10% in bone marrow, and (5) poor or no response to previously effective drug therapy, It is also suggested that a rational therapeutic management in the chronic phase may help to prevent or delay acute transformation.

Objective Finding characteristic of senile colon diverticula in 70 cases senile colon diverticula diagnosed by colonoscope through comparing and summarizing. Methods From Jan 1997 to Dec 2001, 70 cases older than 60 years old senile colon diverticula diagnosed by colonoscope in endoscopy department of PLA general hospital. Male 54 cases ,female 16 cases .Age from 60 to 84 years old, average age 68.70?5.39. Results ①With age increased, detectable rate of colon diverticula and multiple colon diverticula rised; ②Detectable rate in male higher than female; ③Whether the single or multiple diverticula ,all predilection site is in the right colon, rate of the right to the left is 2.8∶1(42∶15), and the single diverticula is more obvious. Conclusions ①Occurrence of diverticula have relation to age; ②Incidence in the right colon of senile is lower than of young people; ③The left colon diverticula and bilateral colon diverticula in senile is higher than in young people.
