Objective To study the hemodynamic changes of rabbit VX2 liver tumors before and after ethanol injection by perfusion imaging of MSCT and investigate the correlation between perfusion parameters and microvessel density (MVD). Methods All of 15 Japanese long-ear white rabbits were divided into control group and experiment group. All rabbits were inoculated with VX2 liver tumor. Perfusion imaging of MSCT scans were conducted in 5 rabbits in the control group on the 14 th day after VX2 tumor inoculation, and the borders of the tumors were stained with immunohistochemical stains, and MVD was measured by anti-CD34. Perfusion imaging of MSCT scans were conducted in all 10 rabbits in the experiment group on the 14 th day after VX2 tumor inoculation. Then absolute alcohol was injected into the tumors by laparotomy. CT scans were conducted 3 and 30 days after absolute alcohol injection, and the borders of the tumors were stained immunohistochemically, and MVD was measured by anti-CD34. The differences of perfusion parameters such as hepatic blood ( BF), hepatic blood volume (BV), mean transit time ( MTT),permeability of capillary vessel surface (PS), and hepatic arterial fraction (HAF), hepatic arterial perfusion (HAP) were compared to evaluate the liver hemodynamic changes. Statistical repeated measurement t test, correlation analysis were performed. Results BF of border of the tumor between pretreatment, 3 days after ethanol injection and 30 days after ethanol injection were ( 280. 62 ± 59. 87 ),(322.03 ± 86. 94 ), ( 177.05 ± 75.96) ml · min -1; HAF were 0. 59 ± 0. 08, 0. 89 ± 0. 12, 0. 23 ± 0. 07;HAP were ( 189. 26 ± 25.46), ( 251.57 ± 31.78 ), (40. 90 ± 5.17 ) ml · min - 1 · ml - 1. HAP increased significantly after ethanol injection 3 days ( P ＜ 0. 05 ); BF, HAF, HAP decreased significantly 30 days after ethanol injection compared with 3 days after ethanol injection ( P ＜ 0. 05 ); BF, HAF, HAP decreased significantly 30 days after ethanol injection compared with pre-treatment ( P ＜ 0. 05 ). It showed positive correlation between BF, PS, HAF, HAP and MVD (r=0. 916, 0. 726, 0. 870, 0. 889; P ＜0. 05). MVD decreased significantly compared with the control group (43.9 ± 4. 0)/HP 30 days after ethanol injection (21.8±3.5)/HP (t = 12.271, P ＜0.05). Conclusion Perfusion imaging of MSCT can detect the hemodynamic changes in rabbit VX2 liver tumors, and also in tumors before and after ethanol injection. CT perfusion can take the place of MVD to evaluate the tumor angiogenesis.

OBJECTIVETo compare the curative effects of primary osteoporosis treated with heat-sensitive point moxibustion and Gaitianli (Oyster Shell and Calcium Carbonate Chewable) tablets for oral administration and explore the treatment mechanism.

METHODSSixty cases of primary osteoporosis were randomly divided into a heat-sensitive point moxibustion group (moxibustion group) and a Gaitianli tablets group (medication group), 30 cases in each group. In the moxibustion group, the heat sensitized points were searched around Zusanli (ST 36), Pishu (BL 20), Shenshu (BL 23) and Mingmen (GV 4) and treated by heat-sensitive point moxibustion; in medication group, Gaitianli tablets were taken by oral administration, 3 pills for once and 3 times a day. The curative effects, bone mineral density (BMD), alkaline phosphatase (S-AKP) and urinary calcium to creatinine ratio (U-Ca/Cr) in both groups were observed before and after treatment.

RESULTSThe total effective rate was 86.7% (26/30) in moxibustion group, superior to that of 76.7% (23/30) in medication group (P < 0.05). After treatment, the BMD of lumbar vertebrae (L2-L4) mean was improved (P < 0.05), and the S-AKP and U-Ca/Cr were reduced (all P < 0.05); in medi cation group, the indexes above were no obvious changes (all P > 0.05).

CONCLUSIONThe therapeutic effect of primary osteoporosis treated with heat-sensitive point moxibustion is superior to that with Gaitianli tablets for oral administration. The mechanism is restraining bone resorption, increasing bone strength, keeping balance of bone metabolism, in order to increase bone mineral density and improve the clinical symptoms.

Objective To investigate the efficacy of Sunitinib in treating metastatic non-clear cell renal cell carcinoma (RCC).Methods Twenty-two metastatic non-clear cell subtype renal cell carcinoma patients with a median age of 46 years (29 -76 years) were treated with Sunitinib.Fourteen cases were found have metastasis post radical nephrectomy,and the remaining eight cases with metastasis received cytoreductive surgery.Pathological diagnosis showed 12 papillary RCCs,one chromophobe RCC,three collecting duct RCCs,and six unclassified RCCs.The metastatic lesions were located in the lung,lymph nodes,adrenal gland,bone,liver,and thyroid gland.The patients were given the treatment of sunitinib 50 mg qd four weeks on and two weeks off.The median time of treatment was 11 months (4.5 - 24 months).Results The objective control rate was 73％.Three papillary RCC and one chromophobe RCC reached partial remission (PR) and 12 cases maintained stable disease (SD) for more than 12 weeks.And the remaining six cases progressed (PD).Conclusions Sunitinib has definitive efficacy in metastatic papillary RCC,chromophobe RCC,collecting duct RCC and unclassified RCC.Metastatic lesions in lungs and lymph nodes might be more sensitive to Sunitinib.

Objective To evaluate the clinical efficacy and side effects of sunitinib in the treatment of advanced renal cell carcinoma. Methods Forty-five patients with advanced renal cell carcinoma and an average age of 48.6 yrs were treated with sunitinib. Among the study group, 25 were male and 20 were female. In group one, patients received sunitinib treatment in repeated six week cycles consisting of four weeks of sunitinib 50 mg daily followed by two weeks off treatment (schedule 4/2). In group two, a single daily dose of sunitinib 37.5 mg was administrated to 20 patients without off treatment. A CT scan was used to evaluate the treatment efficacy after each cycle and the side effects were recorded accordingly. Results Clinical efficacy could be evaluated in 40 patients. Of these, two achieved complete response, eight achieved partial response, 27 were stable and the remaining eight experienced disease progression with four patients dying during the study period. The side effects of sunitinib in group one and in group two included hypertension 32% (8/25) and 10% (2/20), P=0.02; liver function impairment 32% (8/25) and 20% (4/20), P=0.011; hand-foot skin reaction 68% (17/25) and 60% (12/20), respectively. The incidence of major side effects of sunitinib were different in Chinese patients than from what had been previously reported in studies conducted in US and Europe. Generally, most of the sunitinib side effects were easy to manage. Conclusions There weredifferences between the two groups of Chinese patients treated with different sunitinib protocols. The protocol of sunitinib 37.5mg daily without off-treatment was better than the protocol of sunitinib 50mg daily (schedule 4/2) in regard to liver function impairment and hypertension.
