Objective To observe the effect of calcitonin on senile osteoporosis. Methods Eighty-six osteoporotic patients diagnosed by double-energy X-ray absorptiometry and manifested clinical symptoms and with spinal bone mineral density (BMD) 2 or more were divided into two groups: 46 patients in the observed group were administered 100 IU calcitonin once a day for three days, and changed to 50IU calcitonin once every other day for one month; repeat the administeration method after one month rest and plus oral calcium carbonate vitamin D 600 mg every day for a period of 6 months; another 40 patients in the control group only took calcium carbonate vitamin D 600 mg every day for 6 months. The BMD of L1-4 and hips was examined before and after treatment. Results Bone pain relieving was more obviously in the observed group than that in the control group. BMD of the lumbar spine in the observed group showed remarkable change after treatment(P

Objective To summarize the clinical experienee in surgical treatment for hepatocellular carcinoma (HCC). Methods The clinical data of 7566 HCC patients who had been admitted to Research Institute of Liver Cancer of Fudan University from January 1988 to Deeember 2007 were retrospectively analyzed. The overall survival and recurrence free survival (RFS) rates were eaeulated with Kaplan-Meier survival curve. All the data were analyzed using Log-rank test and Cox regression model. Results The 3-, 5-, 10-year overall survival and RFS rates of 7164 patients with HCC resection were 56.29%, 41.76%, 26.70%, and 63.92%, 56.12%, 42.97%, respectively, and the perioperative mortality was 1.54%. The 5- and 10-year overall survival rates of patients with small HCC (diameter<5 era) were 58.20% and 38.47%, which were significantly higher than 31.42% and 20.43% of patients with large HCC (diameter >5 cm) (X2 =535. 568, P <0.01). The 5-year overall survival rotes of HCC patients with resection after down-staging (n = 110), re-resection after recurrence (n = 515), and tumor thrombus in portal vein (n = 168) were 51.26%, 67.28% and 26.81%, respectively; nd the 5-year DFS rotes were 77.44%, 13.01% (calculated from the first operation) and 34.90%, respectively. The 3- and 5-year overall survival and DFS rates of 402 patients who had undergone liver transplantation were 60.81%, 55.63% and 64.47%, 58.52%. The independent prognostic factors influencing the overall survival and DFS rates were the size, number and differentiation of HCC and intrahepatic vessel invasion (X2 = 200.539, 27. 536, 96.964,216. 156, P <0.01). Conclusions Early screening, improved safety of surgery, combined therapy and breakthrough in the reseaeh of preventing HCC metastasis and reeurrenee will significantly improve the treatment outcome of HCC.

Objective To evaluate the diagnosis and treatment of focal nodular!hyperplasia of the liver (FNH). Methods Retrospective analysis was made on 60 FNH cases in terms of clinical findings, images, pathologic examination and surgical treatment. Results Of the 60 FNH patients in our hospital from 1993 to 2003, 41 were male and 19 female. The average age was 37 year′s old. Fifty-five cases had single focus, the other five were of multiple lesion, with tumor diameter 10cm in one. Correct preoperative diagnosis was made in 33 cases (55%). The correct diagnostic rate of BUS, CT and MRI was 33.3%, 58.3% and 72.0%, respectively. All 60 cases underwent operation with an uneventful recovery and without recurrence at follow-up. ConclusionsCT and MRI are mandatory for the diagnosis of FNH. Definite preoperative diagnosis is usually difficult even in cases of typical type of FNH. Surgical resection is the treatment of choice when a patient becomes symptomatic or when malignancy could not be excluded.
