Objective To clarify the risk factors of postoperative recurrence of early gastric cancer (EGC)patients who underwent radical gastrectomy.Methods We investigated follow-up records of 336 EGC patients on whom curative operations were performed at the First Affiliated Hospital of Dalian Medical University between January 1994 and January 2008 with special reference to 12 cases of cancer recurrence.Results The 5-year survival rate of D1 was 89.0％,D1 + t was 91.4％,D1 + β was 91.8％,D2 was 92.5％,D3 was 90.0％(P =0.981).The recurrence rate was 3.6％(12/336).The recurrence time was 17-58 months,the survival time was 33-68 months.Six cases suffered from hematogenous recurrences,four cases from lymph node recurrences,two cases from remnant stomach recurrences.The recurrence rate of SM was higher than M(P =0.015),lymph node positive was high than negative(P =0.011),D1 was higher than D2(P =0.025).Conclusions The recurrence rate of EGC correlated with depth of invasion,lymph node metastasis and lymph node dissection.

Objective To discuss the effect of pylorus-preserving gastrectomy for early gastric cancer(EGC). Methods Between August 1995 and December 2005, 52 cases of EGC underwent pyloruspreserving gastrectomy(PPG) and 159 cases of EGC underwent distal gastrectomy(DG), Clinicopathlogic data and follow-up results of the two groups were analyzed retrospectively, and gastric emptying and gallbladder function of 15 cases PPG and 17 cases DG were compared at the same time.Results Compared with DG group, patients in PPG group maintain the body weight, gastric emptying and gallbladder function. There was no significant difference between PPG group (92. 3% ) and DG group (93.1% ) in overall 5-year survival rate ( P = 0. 881 ). The 5-year survival rate of the the PPG group with lymph node dissection was D1 100%, D1+α 92. 3%, D1+β 88.9%, D2 87. 5% respectively.Conclusions For early gastric cancer, the pylorus-preserving gastrectomy is effective for maintaining the postoperative function with similar long term survival as that of distal gastrectomy.

Objective To investigate the effect of different Chinese herbs on cell proliferation and cartilage oligomeric matrix protein(COMP)expression in chondrocyte culture.Methods Chondrocytes isolated from rabbit knee cartilage were cultured for 3 generations with the density of 2?10~4/cm~2 and were verified by collagenⅡimmunohistochemical staining.Rabbit sera containing herbs were obtained after animals orally ad- ministrated herbs at the dosage equivalent to human.At 5% and 10% serum density,cells were cultured in the medium that contained liver-softening herbal compound sera.Subgroups setting at 1,3 and 5 hours after herb intervention were observed.Rabbit and bovine sera were control groups.Seven days after intervention,chon- drocytes proliferation was observed using the MTT assay kit.For the study of COMP expression,chondrocytes were isolated from human knee cartilage supematant.Superuatant COMP level was tested by enzyme-linked immunoabsorbent assays(ELISA)after directly adding compound and extract from liver-softening herbs to the culture at the final concentration of 10 mg/ml for 3 days.Results Liver-softening herbal compound group had significant effect on cell proliferation compared to control,of which,3-hour subgroup was more significant than 1-and 5-hour subgroups(P

We describe two cases in which a forceps imprintdeveloped in the AcrySof ReSTOR IOL optic whileinserting these IOLs into the cartridge with straightclamping forceps. In case 1 ,the AcrySof ReSTOR IOL wasexplanted and observed under scanning electronmicroscopy (SEM). The SEM showed that the stepdesign of ReSTOR Multifocal IOL was well maintained. Incase 2, visual acuity, contrast sensitivity and wavefrontmeasurements were performed and no specific changeswere found. Strong evidence does not exist that suggeststhe on-axis forceps imprint can significantly compromisevisual acuity.

Objective To study the impact of enteral nutrition (EN) or parenteral nutrition (PN) in postoperative colorectal cancer patients on viscera organ function and "passing wind" time.Methods Totally 30 patients with colorectal cancer joined this study with informed consent.Patients were randomly divided into EN group and PN group.Both two groups were given nutritional support from the first post-operative day to the 7th post-operative day.The pre-operative and post-operative viscera organ functions and the recovery time of gastrointestinal functions are observed.Results Total bilirubin was significantly lower in EN group than in PN group (P ＜ 0.05).The length of post-operative hospital stay was significantly shorter in EN group than in PN group (P ＜0.01).The post-operative complications were not significantly different between two groups (P ＞ 0.05).Conclusion Postoperative EN support is beneficial for colorectal cancer patient in terms of lower bilirubin levels,shorter post-operative hospital stay,and lower cost.

The spores suspension of Streptomyces roseosporus D-38 irritated with 20mW He-Ne laser for 20 min were incubated on G1 medium plates containing 1. 9?g/mL of streptomycin. Ten percent of mutants increased the potency of daptomycin by streptomycin-resistance method, including the mutant LC-54, which could produce daptomycin 81. 2 mg/L, which was 39% higher than that of the beginning strain by flask fermentation.

?AIM: To observe the clinical curative effect of the intravitreal injection of anti-VEGF antibody combined with the implantation of Ex-press glaucoma drainage device for neovascular glaucoma ( NG) .?METHODS:A retrospective analysis of 20 patients with NG, who got the intravitreal injection of anti -VEGF antibody combined with the implantation of Ex-press. The visual acuity, intraocular pressure ( IOP ) , iris neovascularization fade and intraoperative and postoperative complications were observed at 1wk, 1, 3 and 6mo postoperatively.?RESULTS:The average IOPs of 20 patients were 47 ± 5.6mmHg, 13.4 ±3.6mmHg, 15.3 ±4.2mmHg, 16.9 ± 5.3mmHg and 18.7 ±6.9mmHg preoperatively and postoperatively 1wk, 1mo, 3mo and 6mo with statistical difference (P<0.05).The intraoperative and postoperative complications of the implantation of Ex-press mainly included early shallow anterior chamber, drainage tube obstruction, filtering bleb scarring. There were 8 eyes with filtering bleb scarring with normal IOP.?CONCLUSION: The intravitreal injection of anti-VEGF antibody combined with implantation of Ex -press is effective for NG, which can significantly reduce the IOP.

Objective To explore the role of the autoantibodies against ?_1 and ?_1-adrenergic receptor(?_1-receptor)in the development of hypertension with renal failure.Methods The epitopes of the second extracellular loop of ?_1-receptor(197-222) and ?_1-receptor(192-218) were synthesized and used respectively to screen sera autoantibodies in patients with hypertension and renal failure(n=61),hypertension without renal failure(n=60) and healthy blood donors(n=40,control) by ELISA.Results The positive rates of the autoantibodies against ?_1-receptor(62.3%)and ?_1 receptor(50.8%) in patients with hypertension with renal failure were higher than those of patients with hypertension without renal failure(13.3% and10.0%)(P
