Objective To investigate the significance of anti-SmD1 antibody and other auto-antibod- ies in systemic lupus erythematosus(SLE).Methods Forty-four SLE patients and 136 other rheumatic dis- eases patients were studied.The later group included Sj(?)gren's syndrome,undifferentiated connective tissue disease,ankylosing spondylitis,and rheumatoid arthritis.Immunoblotting was used to measure,the anti-SmD1 antibody,ANuA and anti-SSA60 000 antibody.ANA and anti-dsDNA were detected by indirect immunofluo- rescence,immunodotting was used to measure the anti-Sin antibody.Results The seropositive rate of anti- StuD1 was 47.7% in SLE patients.It was much higher than that of anti-Sm(P

Objective To explore the value of endoscopic mini-incision greater saphenous vein harvesting for coronary artery bypass operation. Methods A total of 411 patients scheduled for coronary artery bypass operation were given either endoscopic vein harvesting(EVH Group,n=136) or open vein harvesting(OVH Group,n=275),based on patient's willingness.The operation outcomes and incision complications were compared between the two groups. Results The incidence of various incision complications was significantly lower in the EVH Group(18.4%,25/136) than in the OVH Group(36.7%,101/275)(?~2=14.406,P=0.000).As compared with the OVH Group,the EVH Group had lower incidences of edema(1.5% vs 35.3%;?~2=56.861,P=0.000),paraesthesia(7.4% vs 33.8%;?~2=33.937,P=0.000),hematoma(16.2% vs 27.3%;?~2=6.214,P=0.013),and incisional liquefaction(0.7% vs 8.7%;?~2=10.174,P=0.001) of the lower extemity.The total operation time were 226.3?28.5 min in the EVH Group and 224.7?19.2 min in the OVH Group,without significant difference between the two groups(t=0.673,P=0.502).Early graft failure happened in 1 case in each of the groups,without significant difference between the two groups(?~2=0.000,P=1.000).The numbers of distal coronary anastomoses were 3.6?0.8 in the EVH Group and 3.3?1.0 in the OVH Group,with significant difference(t=3.049,P=0.002). Conclusions Endoscopic greater saphenous vein harvesting can significantly reduce the morbidity associated with incision complications,whereas does not prolong the operative time,increase the incidence of early graft failure,and decrease the number of distal coronary anastomoses.

AIM:To evaluate the feasibility and significance of nasal endoscope combined with Neodymium-doped Yttrium Aluminium Garnet ( Nd:YAG ) laser in the treatment of recurrent dacryocystitis.
METHODS: Forty-eight cases (48 eyes) with recurrent dacryocystitis were treated by nasal endoscope combined with Nd:YAG laser. The tubes were kept in place for 3-6mo after operation. The follow-up time was 3-18mo.RESULTS: Symptoms was completely resolved in 46 eyes and improved in 2 eyes, the cure rate was 100%. There were no other complications.
CONCLUSION: Nasal endoscope combined with Nd:YAG laser provides an ideal therapeutic for recurrent dacryocystitis because of its many advantages such as a few complications, simple operation, no scars on face and so on and is fit for clinical application in primary hospitals.

Objective To investigate the prognostic factors of EGC patients,especially the relationship between prognosis and tumor size.Methods Clinical data of 119 EGC cases from 1998 to 2002 were analyzed retrospectively.Results The overall 5-year survival rate was 90.9%.and the survival rate of patients with tumor D＜2 cm.2 cm≤D＜4 cm and D≥4 cm respectively was 100%,92.0%and 80.8%(P=0.024).In this group,tumor stage,lymph node metastasis and tumor invasion depth did not affect the survival statistically.There was no correlation between tumor size and other prognostic factors.Conclusion Tumor size is an independent prognostic factor of patients with EGC,which may have some relevance to the surgical approach of EGC.

AIM: To investigate protective effect of N-acetylcysteine (NAC) on liver and lung in mice after hepatic ischemia/reperfusion injury. METHODS: BALB/c mice were used in a model of partial hepatic ischemia/reperfusion (I/R) injury.They are divided randomly to sham-operated control group(SH), hepatic I/R group or NAC pretreated in hepatic I/R group(I/R-NAC).The level of TNF-α in protal vein and plasma ALT were measured at 1hour and 3 hour, respectively after reperfusion.Lung tissue wet-to-dry(W/D) weight ratio compared. RESULTS: Lung tissue W/D ratio showed significant difference between two groups; The expressions of TLR2/4 mRNA in liver and lung increased obviously after hepatic I/R injury. Histological evaluation showed several changes in lung tissue in I/R group.The level of TNF-α and ALT in protal vein increased continually in I/R group at 1hour and 3 hour of reputation compared with SH group.The level of TNF-α and ALT declined significantly in the group pretreated by NAC. CONCLUSION: N-acetylcysteine can inhibit the activation of TLR2/4 and reduce TNF-α secretion resulted from I/R injury it might abate liver and lung injury following partial hepatic ischemia-reperfusion in mice.

OBJECTIVE:To study the protective effects of total flavone from Prunus cerasifera fruits(PCE)on alcoholic liver disease(ALD)in rats,and provide experimental basis for developing new medicines for anti-ALD. METHODS:40 rats were ran-domly divided into normal group(distilled water),model group(distilled water),silibinin group [positive control,30 mg/(kg·d)] and PCE high-dose,low-dose groups [80,40 mg/(kg·d)],8 in each group. All rats were intragastrically administrated(10 mL/kg) every morning,once,for 6 weeks;meanwhile,except for normal group,rats in other groups received 50% alcohol(10 mL/kg) once intragastrically every afternoon to induce ALD model. After administration,heart,liver,spleen and other organ indexes,sub-cutaneous fat,brown fat,abdominal fat indexes were determined,as well as serum biochemical indexes [glutamate transaminase (ALT),aspartate aminotransferase(AST),total bilirubin(TBIL),direct bilirubin(DBIL),indirect bilirubin(IBIL),gamma-glu-tamyl transpeptidase(GGT),and total cholesterol(TC),triglyceride(TG),high-density lipoprotein(HDL),low-density lipopro-tein (LDL)] level and liver biochemical indexes [superoxide dismutase (SOD),malondialdehyde (MDA),glutathione peroxidase (GSH-Px),TC,TG] and TC,TG levels in feces;pathological changes of liver and kidney tissues were observed. RESULTS:Compared with normal group,heart,liver,spleen indexes,subcutaneous fat,abdominal fat indexes in model group were in-creased(P<0.05 or P<0.01),brain index and brown fat index were decreased(P<0.05);HDL level and HDL/TC ratio in serum were decreased,other serum indexes were increased(P<0.05 or P<0.01);SOD,GSH-Px levels in liver tissue were decreased, other above-mentioned liver biochemical indexes were increased(P<0.01);TC,TG levels in feces were increased(P<0.01);liv-er and kidney showed obvious lesions. Compared with model group,the above-mentioned indexes in silibinin group and PCE high-dose group were significantly improved (P<0.05 or P<0.01);ALT,AST in serum and MDA level in liver tissue in PCE low-dose group were significantly decreased(P<0.01),and SOD,GSH-Px levels in liver tissue were significantly increased(P<0.05);lesion degree of liver and kidney and lipid accumulation in liver were reduced in administration groups. CONCLUSIONS:PCE may play a role in anti-ALD by anti-oxidation,promoting liver cell regeneration and regulating lipid metabolism.

Objective To explore a method to improve the nutritional state and immune function of patients after radical gastrectomy,and to decrease postoperative complication rate and accelerate recovery from operation.Methods In line with the concept of fast tract surgery (FTS),a new perioperative nutritional schedule was made for patients prior to radical gastrectomy,ehich included preoperative nutritional risk screen and prophylactic enteral nutrition,early postoperative light enteral nutrition,early ambulation and perioperative nursing care.Patients with gastric cancer were randomly assigned into fast track group or a simple control group.New perioperative schedule was executed in the patients of fast track group and traditional nutrition support in control group.After operation,serum albumen was measured to evaluate the patient's nutritional state and serum IgA to evaluate gastrointestinal immune function.In addition,the time to passage of flatus,postoperative recovery time and complication rate after operation were compared.Results Patiens in FTS group (n=35) showed higher serum albumin and serum IgA on d1 and d3 after operation than those in the control group (n=25) (P
