Soil salinity can limit plant growth and productivity. The cultivation of tolerant varieties is convenient and cost-effective for making good use of the saline *** sweet sorghum plant has a high tolerance for saline alkaline soils. The KF1210-3 and KF1210-4 early-maturity mutants of sweet sorghum were obtained via carbon ion irradiation. The study assesses the productivity of three sweet sorghum cultivars(KF1210-3, KF1210-4, and KFJTCK) which were grown in intermediate(4.6 d S m^(-1)) and high(11.9 d S m^(-1)) soil salinity. The sweet sorghum grown in the soil salinity of 4.6 d S m^(-1)produced 50.00–57.30 %greater fresh weight than that in the soil salinity of11.9 d S m^(-1), while the difference was not as obvious among the dry biomass of the three sweet sorghum cultivars. Moreover, the Brix degree of the sweet sorghum grown in the soil salinity of 11.9 d S m^(-1)was greater than that grown in the soil salinity of 4.6 d S m^(-1). The heavy ion irradiation experiment is of great significance in screening plant mutants, improving environmental conditions, and assessing the productivity. This process, in turn, aids in the understanding of the effects of the biochemical and physiological mechanisms of salt stress.

AIM：To characterize the factors of the improved survival following combined pancreaticoduodenectomy（PD） and gastrectomy for the treatment of advanced gastric cancer with pancreaticoduodenal region involvement.METHODS：From 1995 to 2004,53 patients with primary gastric cancer were diagnosed with synchronous（n = 44） or metachronous（n = 9） pancreaticoduodenal region *** these,17 patients（32%） underwent total gastrectomy（TG） or distal subtotal gastrectomy（SG） combined with PD *** preoperative demographic,clinical information,clinicopathologic features and the surgical results of these 17 patients were considered as factors influencing survival and were analyzed by the Kaplan-Meier method with log-rank comparison.RESULTS：The actual 1-and 3-year survival rates of these 17 patients after resection were 77% and 34%,respectively,and three patients survived for more than 5 years after *** tumor-free resection margin（P = 0.0174） and a well-differentiated histologic type（P = 0.0011） were significant prognostic factors on univariate *** mortality occurred within one mo after operation,postoperative weight loss of different degree was present in all the patients with TG and 12 cases had other *** were 9（53%） cases of recurrence in 5-48 mo after *** survival rate in the palliative and explorative group was significantly（P = 0.0064） lower than in the combined PD group.CONCLUSION： Judicious use of en bloc PD and gastrectomy and strictly preventing postoperative complications may improve the long-term survival for advanced gastric cancer patients with pancreaticoduodenal region involvement. Well-differentiated histology and negative resection margin are the most important predictors of long survival.

AIM: To study the correlation between genetic polymorphism of cytochrome P450IIE1 (CYPIIE1) and fatty ***: Peripheral blood mononuclear cells were collected in 56 patients with fatty liver, 26 patients without fatty liver and 20 normal controls. Then PCR-RFLP was used to analyze genetic polymorphism of CYPIIE1 in monocytes on the region of Pst I and Rsa ***: The frequency of homozygotic C1 gene in patients with alcoholic fatty liver (28.6 %), obese fatty liver (38.5 %), or diabetic fatty liver (33.3 %) was significantly lower than that of the corresponding patients without fatty liver (100 %, 100 % and 80 % respectively), while the frequency of C2 genes, including C1/C2 and C2/C2, was significantly higher (71.4 %/0 %, 61.5 %/0 %, and 66.7 %/20 %) (Pliver patients (100 %/0, 100 %/0, and 80 %/20 %) was not significantly different from that of the normal controls (85 %/15 %) (P>0.05).CONCLUSION: The genetic polymorphism of CYPIIE1 on the position of Pst I and Rsa I is related to the susceptibility of fatty liver. Besides, C2 gene may play a key role in the pathogenesis of fatty liver.

Rheumatic heart disease is still highly prevalent in .developing countries where the incidence of coronaryartery disease （CAD） is also arising. Consequently the occurrence of coexistent CAD and mitral stenosis （MS） dominantly caused by rheumatic fever is more frequent in these countries. Comorbidities such as pulmonary and renal dysfunction occur frequently in these aging populations. Off-pump surgery is widely applied in patients with concomitant CAD and severe comorbidities due to lower incidence of postoperative morbidity. Closed mitral commissurotomy （CMC） is a well established treatment for patients with mitral stenosis. We report here a case of moderate stenosis combined with seriously diffuse 3-vessel CAD and severe chronic obstructive pulmonary disease （COPD） in an elder male treated with off-pump coronary artery bypass （OPCAB） plus CMC.
