Objective: This study aimed to investigate the effects and side effects of Jinlong Capsule with concurrent three-dimen-sional conformal radiotherapy for advanced primary hepatic carcinoma. Methods: A total of 85 patients with inoperable primary hepat-ic carcinoma were randomly divided into a research group and a control group. Forty-two cases in the control group were treated with three-dimensional conformal radiotherapy alone, whereas 45 cases in the research group were treated with three-dimensional conformal radiotherapy and Jinlong Capsule oral administration. All cases were irradiated with 6 MV X-rays, 2 Gy per day, 5 days a week to a to-tal dose of 60 Gy in 6 weeks. Jinlong Capsule (1 g) was administered orally three times daily until disease progression for at least one year. The short-term therapeutic effect and adverse events were evaluated for 2 months after treatment. The long-term therapeutic effect was assessed at the end of follow-up. Results: The objective response rate of the research group was significantly higher than that of the control group at 74.4% and 47.6%, respectively (P=0.011). The disease control rates were 97.7% and 85.3% (P=0.030) for the re-search and control groups, respectively. No obvious difference was found between the complete response rates of the two groups, 20.9% and 14.3% (P=0.422). The 1- and 3-year overall survival rates of the research group (74.4% and 34.9%) were significantly high-er than those of the control group (66.7% and 16.7%) at P=0.046. The 1- and 3-year progression free survival rates of the research group (74.4% and 27.9%) were significantly higher than those of the control group (61.9% and 9.5%) at P=0.038. The main adverse events were grade 1–2 bone marrow suppression, abdominal distension, nausea, vomiting, and transaminase elevation. No obvious dif-ference was observed between the adverse events in the two groups. Conclusion: The short- and long-term effects of the combination therapy of Jinlong Capsule and three-dimensional conformal radiotherapy on primary hepatocellular carcinoma were significantly high-er than those of three-dimensional conformal radiotherapy alone. The patients also tolerated the adverse effects.

The basic structure, primary parameters of PET/CT and the clinical application value on tumor system, cardio-vascular system and nerval system are simply introduced. The 64 slices PET/CT is significant in directing coronary heart disease diagnosis and treatment. The PET of the 18F-FDG cardiac muscle metabolism and coronary artery imaging can be operated by this equipment at the same time, which can confirm the activeness of the cardiac muscle and the blood-supply for the coronary arterial distributing. This has a determinative meaning for the choosing of Rx.

Objective To evaluate the efficacy and survival rate of neoadjuvant chemotherapy with docetaxe and pirarubicin in triple negative breast cancer (TNBC).Methods Total 51 breast cancer patients were divided into TNBC group (n =26,including 16 of stage Ⅱ and 10 of stage Ⅲ patients) and non-TNBC group (n =25,including 14 of stage Ⅱ and 11 of stage Ⅲ patients).All patients received a median of 4 treatment cycles with TAC regimen [docetaxe 75 mg/m2 on day 1,pirarubicin 40 mg/m2 on day 1 and cyclophosphamide (CTX) 500 mg/m2 on day 1 of each 21 day cycle].The efficacy of treatment and survival rate of two groups were evaluated.Results In TNBC group,9 out of 26 (34.62 ％) patients achieved clinical complete response (cCR),and 14 (53.85 ％) had partial response (cPR).Overall,88.46 ％ of TNBC patients had clinical response and 26.92 ％ (7/26) showed pathology complete response (pCR).In non-TNBC group,6 (24.00 ％) patients reached cCR and 8 (32.00 ％) showed cPR.The overall response rate was of 56.00 ％,and 4 (16.00 ％) patients achieved pCR.The overall 3-year survival rates in TNBC and non-TNBC groups were 73.08 ％ and 88.00 ％,respectively,indicating a poorer prognosis of TNBC.The 5-year survival rates of TNBC patients with and without pCR were 88.89 ％ and 47.06 ％,respectively.Conclusion TAC regimen improves the prognosis for locally advanced TNBC,indicating that the neoadjuvant chemotherapy is effective and safe for TNBC patients.

Objective To explore the effect of chronic compound stress on serum adiponectin level and AdipoR2 expression in rats.Methods Forty male Sprague-Dawley rats were randomly divided into two groups:the stress group underwent chronic compound stress and the control group was fed normally.After 8 weeks of stress or feeding,the serum adiponectin,blood glucose ,insulin resistance and HbA1 C,HDL-C,LDL-C,triglyceride and total cholesterol were measured.Results ①After 8 weeks of stress,the score of open-field behaviors and 24-h urocortisol were significantly different between the stress and control groups (32.0 ± 8.6 vs.52.0 ± 12.7,5.8 ± 0.4 vs.(5.3 ±0.1 ) ng/L,repectively; P ＜0.05 or 0.01 ) ;②After 8 weeks of stress,the adiponectin,total cholesterol ,triglyceride,HDL-C,InIR and HbA1 C were significantly different between the two groups (P ＜ 0.05 or 0.01 ) ;③After 8 weeks of stress,there were significant difference on the expression of AdipoR2mRNA and protein between the two groups (P ＜0.01 ) ,with the expression of AdipoR2mRNA of 0.67 ±0.04 and 1.00 ±0.11 and the expression of protein of 0.73±0.02 and 1.00 ± 0.04 in the stress and control group,respectively.Adiponectin was negatively related with HbA1 C,LDL-C and IR ( r = - 0.26,- 0.88 and - 0.37,P ＜ 0.05 or 0.01 ),and positively related with HDL-C ( r =0.78 ,P ＜0.01 ).Conclusions In rats,chronic compound stress decreases the level of serum adiponectin and the expression of AdipoR2 in liver.

A simple spcctrophotometric method for determination of total rare-earth metals in food is presented. Weigh 5 gm of dry sample in a dish. After soaking the sample more than half an hour with 10 ml 3N H2SO4, evaporate to dryness on a hot plate and ash at 600℃. Dissolve the ash in 1 ml 6N HCl, and evaporate to dryness. Dissolve the residue in 2 ml water, and transfer it to a 10 mi-graduated tube. Wash the dish repeatedly with small amount of water. Transfer the washings to the same tube, and dilute to 10 ml with water. Pipette two portions of aliquots of 4 ml sample solution to two 10ml graduated tubes in which 2 ml of HCOOH-NH3 buffer (pH 3.7) is added. After mixing, add 1 ml each of 10% sulphosalicylic acid solution and 5% ascorbic acid solution. Make volume to 8 ml with water. Mix thoroughly.

Objective: To study the amount of fat, cholesterol and fatty acid intake in China and provide the basic material for dietary guidance. Methods: Two areas were selected both in North and South China and each area included 3 provinces, or municipality or autonomous region. Three representative survey sites were selected in each province, or municipality or autonomous region. Dietary survey was conducted by the method of weighing and recording and cooking method was also recorded. The amount of food consumption was calculated as standard person (adult male, light physical activity). All foods were gathered as 12 kinds of foods, and each kind of food was cooked and then mixed. The content of fat and fatty acid was analyzed for 8 kinds of foods and the content of cholesterol was analyzed for 4 kinds of foods. The intake of fat, fatty acid and cholesterol per capita was calculated. Results: The amount of fat intake among North I, North II, South I, South II was 70.5 g, 46.5 g, 58.7 g, 71.0 g respectively and the amount of cholesterol intake was 329.6 mg, 128.5 mg, 400.9 mg, 306.0 mg respectively. The main source of dietary fat was from meat and vegetables. Egg was the main source of dietary cholesterol and meat and egg were both the main source of dietary cholesterol in south II area. About 90% of saturated fatty acid was palmitic acid and stearic acid and 90% of monounsaturated fatty acid was oleic acid. Linoleic acid was the principal n-6 polyunsaturated fatty acid and linolenic acid was the principal n-3 polyunsaturated fatty acid. The ratio of S∶M∶P in North I was 1∶1.1∶1, in North II was 1∶1.6∶1.3, in South I was 1∶1.6∶1.3 and in South II was 1∶1.5∶1. Conclusion: The amount of fat intake and fatty acid profile was quite different among different areas and the dietary guidance should be more pertinent The current cholesterol intake was more than dietary guidance in most areas. In addition to egg, meat was also an important source of cholesterol.

Objective To observe the effects of GABA on proliferation, cell cycle and expression of MMP-2, MMP-9 of pancreatic cancer cell line SW1990. Methods The effects of different concentration of GABA (0 ～ 320 μmol/L) on proliferation and cell cycle of pancreatic cancer cell line SW1990 was investigated by MTT assay and flow cytometry analysis, respectively. Expressions of MMP-2 and MMP-9 proteins were evaluated by Western blot analysis. Results GABA could promote the proliferation of SW1990 cells and influence the distribution of cell cycle, which made less cells of G0/G1 phase and more cells of S and G2/M phase. The value of A570 after GABA pretreatment at a dose of 320 μmol/L was 1. 11 ± 0.03, which was significantly higher than that in the control group (0. 56 ± 0.01, P < 0. 01 ), the cells of G0/G1 phase was (46.18 ± 1.12 )% ,which was significantly lower than (87.29 ± 1.34)% in the control group (P < 0. 01 ) ;the expressions of MMP-2 mRNA, MMP-9 mRNA and their proteins were 8.6, 6.8, 10.5, 8.4, respectively, which were significantly higher than those in the groups of the doses of 0 ～ 40 μmol/L ( P < 0. 05 ). Conclusions GABA could influence the proliferation and expression of MMP of SW1990 cells.

AIM: To investigate the expression, distribution and significance of nuclear factor κB (NF-κB) in experimental hepatic fibrosis.METHODS: Wistar rats were randomly divided into normal control group, hepatic fibrisis model group and the pyrrolidine-1-dithiocarboxylic acid ammonium sail (PDTC) group. The PDTC group was treated with subcutaneous injection of carboan tetrachloride, and treated with PDTC by oral administration. The content of hydroxyproline was measured. Endotoxin was determined with a Limulus amebocyte lysate test kit. The alanine aminotransferase (ALT) in plasma was measured by laishi method. The content of malondialdehyde (MDA) in liver tissue was detected by means of TBA method. The expression of NF-κB was determined by immunohistochemistry. The expression of connective tissue growth factor (CTGF) was measured by Western blotting.RESULTS: In control group, just a small amount of NF-κB p65 was expressed in the cytoplasm of a few hepatocytes around central veins. In model group, the positive staining of NF-κB p65 was expressed in cytoplasm and nucleus, mainly in fibrous stepta, hepatic sinusoid and partial vascular endothelial cells, part of proliferating ductular epithelial cells and impaired hepatocytes. The positive staining began to increase from the first week. The expression of NF-κB in the liver tissues in PDTC group was lower than that in model control group (P<0.05). The ET levels and expression of NF-κB and CTGF began to increase significantly in liver fibrosis group. The levels of plasma ET and expression of NF-κB and CTGF were correlated positively with each other. In PDTC group, ET content in plasma increased significantly at first, then began to decline at the end of the test. The expression of NF-κB and CTGF in liver tissues in PDTC groups was lower than that in model group. Furthermore, the expression of NF-κB in liver tissues in PDTC group was correlated positively with CTGF. The levels of plasma ET were not correlated with the expression of NF-κB and CTGF.CONCLUSION: ET may up-regulate the expression of CTGF by activating NF-κB.
