AIM: To investigate the effect of L-phenyla lanine on vascular remodeling in hypertensive rats. METHODS: Vascular remodeling was measured by laser scanning conf ocal microscopy (LSCM) in mesenteric resistance arteries isolated from spontaneo usly hypertensive rat (SHR) and normotensive Wistar-Kyoto (WKY) rat. The effect of L-phenylalanine on the hypertensive vascular remodeling was observed. The thi rd most distal first-order branches of mesenteric resistance arteries from SHR a nd WKY were studied. The arteries were fixed under pressure. The segments were s tained with the nuclear dye propidium iodide. The diameter, wall thickness and o rientation angle of smooth muscle cells were measured with LSCM. RESULTS: Compared with WKY, SHR arteries showed: (1) smaller lum en, (2) increased wall thickness, (3) disorganized orientation angle of smooth m uscle cells. L-phenylalanine treatment induced specific changes in the lumen, wa ll thickness and the orientation angle of smooth muscle cells. CONCLUSIONS: Hypertension induces vascular remodeling of the bra nches of mesenteric arteries from SHR. L-phenylalanine inhibits the vascular rem odeling process of hypertension.

Objective To evaluate the effect and complication of inductio n chemot herapy combined with three-dimensional conformal radiation therapy (3DCRT) for l ocally advanced non small cell lung cancer (NSCLC). Methods Ninety-two such pa t ients were randomized into radiation therapy alone group(RT-, 50 patients) and i nduction chemotherapy combined radiotherapy group (CMT-, 42 patients). The indu c tion chemotherapy consisted of 2-4 cycles of platinum-based regimen. Results Th e overall median survival time was 15 months with 12 months in the RT group and 18 months in the CMT group(P=0.014)respectively. The 1-year o verall survival rates were 48.6% and 71.2% in RT and CMT group,respectively (P=0.004). The 2-year survival rates w ere 20.8% and 37.6% in RT and CMT group, respectively (P=0.0 41). Treatment was w ell tolerated and the toxicities were similar in either group. C onclusion The ad dition of induction chemotherapy to 3DCRT takes a survival advantage over 3DCRT alone for Stage Ⅲ NSCLC without increasing toxicities.

Objective To observe the effect of RNA interference binding immunoglobulin protein (BiP) on expression of bone markers and keytranscription factors in osteoblast exposed to fluoride.Methods MC3T3-E1 cells were used as osteoblast model in vitro.The cell viability was test with cell counting Kit-8 after cells were administrated with varying concentrations of fluoride [0.0 (control),0.1,1.0,2.0,4.0,8.0,16.0,20.0,32.0 and 64.0 mg/L] for different duration.Cells transfected with small interfering RNA (siRNA) BiP were exposed to fluoride (2.0,8.0 and 20.0 mg/L) for 2 days.Real-time PCR and Western blotting technique were used to determine the gene and protein levels of BiP.Meantime,the mRNA expression of bone markers and key transcription factors was investigated by real-time PCR.Results The difference of all viability in fluoride-dose groups was statistically significant exposed for 1,3,7 and 14 days (F =46.7,118.6,214.6,325.6,all P ＜ 0.05).Expression of BiP significantly increased in cells exposed to 20.0 mg/L compared to that of control (11.22 ± 3.25 vs.7.94 ± 1.31,P ＜ 0.05).The expression of alkaline phosphatase (ALP) elevated in cells exposed to 2.0 mg/L of fluoride (12.81 ± 3.62 vs.6.86 ± 2.13,P ＜ 0.01);conversely,it significantly reduced in cells exposed to 20.0 mg/L of fluoride (0.89 ± 0.17 vs.6.87 ± 2.14,P ＜ 0.01).Cells transfected with siRNA BiP significantly decreased the ALP expression in cells exposed to fluoride compared to that of cells only exposed to the same concentration of fluorine (12.81 ± 3.62 vs.7.43 ± 2.06;5.92 ± 2.38 vs.3.96 ± 0.21,all P ＜ 0.05).Cells transfected with siRNA BiP and administrated with 2.0 mg/L significantly reduced the osteocalcin expression (4.29 ± 0.99 vs.1.29 ± 0.86,P ＜ 0.01).Similarly,expression of runt-related transcription factor 2 (Runx2) significantly increased in cells exposed to 2.0 mg/L.However,expression of Runx2 significantly decreased in cells transfected with siRNA BiP and administrated with fluoride.Cells transfected with siRNA BiP significantly decreased the Runx2 expression in cells exposed to 2.0 mg/L and 20.0 mg/L compared to that of cells only exposed to the same concentration of fluorine (1.13 ± 0.22 vs.6.61 ± 0.48;0.02 ± 0.02 vs.1.50 ± 0.38,all P ＜ 0.01).As the downstream of Runx2,the expression of osterix in cells treated with different concentrations of fluoride was similar to that of Runx2.Conclusion BiP is not directly involved in the process of osteoblast differentiation induced by fluoride;instead,it affects the expression of bone markers and key transcription factors in osteoblast exposed to fluoride.

Five population groups, including farmers living in Veining (a cold hilly southern county), farmers and labourers in Shijiazhuang (a northern district), coastal fishermen in Zhoushan and "Yi" nationality farmers in Veining (where the incidence of hypertension is very low in China) were selected randomly (467 male subjects, 40-59 years old) to explore nutritional parameters-BP relationships. The results showed; (1) Pulse rate, QI and BP were lowest in Veining "Han" and "Yi" nationality groups. (2) Values of blood and urine nutritional parameters were in close accord with the diet customs of the different population groups. (3) Urine Na, Ca, Ca/Mg, urea nitrogen and serum cholesterol, total protein, albumin, uric acid were higher, while urine K was lower in hypertensives. (4) Urine Na, Na/K, Ca/ Mg and serum albumin, total protein, cholesterol, triglyceride, uric acid levels correlated positively, while K inversely with BP on multivariate stepwise regression and/or discrimination analyses. These results suggested high Na (Ca)-intake might be hypertensive, while high K(Mg)-intake an-tihypertensive, the serum protein - BP relationship could not be ascribed as a secondary effect of hemoconcentration in hypertension; a high protein intake, regardless of nature, could be hypertensionogenic; hyperlipidemia seemed to be a risk factor of hypertension, not being the secondary consequence to high BP. In designing a strategic protocol for primary prevention of hypertension, the above should be given due consideration.

Eight populations including 4 Chinese districts and 4 nationalities 484 subjects (male, 40~59 years) were conducted for exploring amino acid (22 sorts)-BP relationship by multi-variate regression and discrimination analyses. Results showed:(1)The different amino acid levels found among "Ka-zak", "Han" and "Uygur" nationalities living in one of the same Xinjiang region might be a reflection of their diverse dietary patterns; while the difference seen between "Han" and "Yi" nationalities living in one of the same Quizhou area, taking similar diet, might be due to the inherited metabolic influence. (2) The levels of aspartic and (or) glutamic acids were the the highest in the Quizhou "Han" and "Yi" groups living in cold hilly area, while other amino acids were comparatively lower, in keeping with their BP, Quetelet's indices and serum urea levels to be the lowest, tentatively denoting that the tissue metabolic turnover rate might be also lower as well in these groups. (3) The serum levels of sulfur containing amino acids in those populations taking much animal foods, were all higher, therefor ethe lower incidences of cardio-cerebro-vascular diseases seen in fishmen can not be thus wholly ascribed to the high intake of fish meat rich in sulfur containing amino acids. (4) From BP regression equations, valine, cysteine, alanine, threonine were found to be the prohypertensives while glycine, leucine, methionine and phenylalanine,the antihypertensives.

Objective To discuss interventional procedures before feeding tube placed in the DSA guidance,influence postoperative enteral nutrition support for the presence of nutritional risk of clinical outcomes in elderly patients with hepatocellular carcinoma. Methods 33 patients acquired with interventional therapy of hepatic carcinoma were selected as the study group.All of patients un-derwent preoperatively the nutritional risk screening and insertion of nasogastric feeding tube under DSA.Enteral nutritional support by the nasogastric feeding tube was used after interventional therapy.33 similar patients underwent parenteral nutritional support af-ter international therapy were selected as the control group.The change of the nutritional indexes,the incidence of the systemic in-flammatory response syndrome,the incidence of infection,and the length of hospital stay after operation were compared between the two groups.Results There were no significant differences in the plasma albumin levels and body weight changes compared between the two groups (P >0.05).However,the incidence of infection and the length of hospital stay were lower significantly in the study group than in the control group (P >0.05).Conclusion The nutritional risk screening before interventional treatment is necessary for the elder patients with hepatic carcinoma.The patients with nutritional risk can be placed the nasogastric feeding tube preopera-tively under DSA,and perform combined nutritional support to promote the recovery of nutritional state after operation.

Objective To explore the mechanism of immunomodulatory activity of triptolide on healthy volunteers peripheral blood mononuclear cells (PBMC)-derived plasmacytoid dendritic cells (pDCs). Methods Healthy volunteers-derived pDCs were sorted by flow cytometry, then incubated with triptolide (0, 5, 10, 30 μg/L). After 24 hours, we detected the concentration of IFN-α, IL-6, TNF-α using ELISA. After 5 days, the cultrural cells were collected and analyzed by flow cytometry, light microscope and electron microscope scanning. Results Triptolide-treated pDCs secreted lower level of IFN-α,IL-6 ,TNF-α, triptolide could inhibit pDCs differentiation to DCs which displayed more immature morphology and immunophenotypes than untreated-pDCs. Conclusion Triptolide could decrease the immune function of pDCs, inhibit differentiation and maturation of pDCs.

Men aged 40-59 years (325 subjects) from 4 districts, 6 populations, 3 nationalities were investigated to explore the relationship between element and blood pressure (BP) . Fe, Mo, Ni, Pb, Si, Sn, Sr, V, Cd, Co, Cr, Cu, Mn, Zn, Ca, and Mg -were measured by ion coupled plasma spectroscopy, Se by catalytic pulse polarography. Results showed; (1) The element levels were different among districts and nationalities. (2) The correlation coefficients among serum Pb, Ni, Si, Sn, V, Cd, Cr were rather high, while Sr behaved relatively independently. (3)Using multivariant stepwise regression and discrimination analysis, serum Sr was found to associate positively with BP in normotensive and hypertensive and total pooled groups without exce-piton. (4) Serum Ca (Ca/Mg), Fe, Co were positively associated, while Cr, Sn inversely associated with BP. (5) The harmful element Cd was unexpectedly found to be inversely associated with BP and it was lower in those populations with high BP levels, which might be ascribed to the non-parallel distribution of certain elements in body tissues and blood. Results also indicated; (1) The levels of essential element Ni, V, Co, Cr were lower in hypertensive group. (2) Serum Ca and urinary Ca were non-parallel, and the former could not accurately reflect Ca-intake. In short, the relationship between element and BP still remains to be elucidated.
