Objective To investigate the relationship between the serum levels of CEA,cAl25,CA19-9 and clinical pathological characteristics in gastric cancel patients.Method The serum levels of CEA,CA125 and CA19-9 in 107 gastric cancer patients before the surgery were detected by electrochemiluminescence immunoassay.Results The preoperative seurm levels of CEA,CA125 and CA19-9 were not correlated with sex,age and the location of the tumor.The serum level of CEA,CA125 and CA19-9 in patients with lymph node metastasis were higher than those in patients without lymph node metastasis.The serum levels of CEA,CA125 and CA19-9 were positively correlated with the depth of tumor invasion and the size of the tumor.The serum levels of CA125 were correlated with the degrees of differentiation.Thehigher the CA125 levels,the lower the degrees of differentiation.But the levels of CEA and CA19-9 were not correlated with differentiation.There were positive.correlations among the serum levels of CEA,CA125 and CA19-9.The correlation coefficient of CA125 and CA19-9 was 0.623(P<0.01),CA125 and CEA was 0.572(P<0.01),CA19-9 and CEA was 0.412(P<0.01).Conclusions The serum levels of CEA,CA125 and CA19-9 in gastric cancer patients are significantly related with the size of the tumor,the depta of tumor invasion and lymph node metastasis.The preoperative serum levels of CEA,CA125 and CA19-9 can provide some reference for formulating the treatment of the gastric cancer patients.

Objective To evaluate CTP,MELD,MELD-AS,MELD-Na,i-MELD and MESO in prognosis of cirrhosis patients who underwent endoscopic injection sclerotherapy (EIS). Methods Seventy-eight cirrhosis patients with integral clinical and follow-up data were enrolled into the study. The area under the receiver operating characteristic (ROC) curve (AUC) was used to compare these six models in predicting mortality risk. The optimal threshold of them to determine the prognostic death risk was calculated by ROC curves. Results Eight patients died within half one year, 11 patients died within the first year. There was no significant difference in gender and age between the survival and death groups. The AUC of the six models higher than 0.800 were. that, 6-month: MELD-AS (0.837), MESO (0.830), MELD (0.830) ; 12-month: MELD (0.822),MELD-AS (0.821),MESO (0.814). Conclusions MELD-AS,MESO,MELD and so on are all accurate predictive systems for 6-month and 12-month of patients who underwent EIS. The value of them are very important in the selection of patients for EIS, and have a certain clinical significance.

Objective: To investigate the effect with its possible mechanisms of zacopride on vasodilatation of isolated coronary arterial rings in experimental rats.
Methods: The tension of vasodilatation of isolated coronary arterial rings of male SD rats was recorded by Powerlab and DMT system. The rats were divided into 4 groups: +Endo (vehicle) group, +Endo (zacopride) group and -Endo (vehicle) group, –Endo (zacopride) group.n=6 in each group. The vasodilatation effects of zacopride on KCl (60 mmol/L) and U46619 (10-6 mol/L) pre-constricted arterial ring were recorded; the effects of different agents on zacopride caused vasodilatation were studied.
Results: In both +Endo (zacopride) and –Endo (zacopride) groups, zacopride showed a dose dependent vasodilatation effect on coronary ring pre-constricted by KCl and U46619. The maximum vasodilatation effect of zacopride in KCl treated+Endo (zacopride) group was (90.15 ± 6.38) %, in U46619 treated-Endo (zacopride) group was (81.67 ± 4.97 ) %; the maximum vasodilatation effect of zacopride in KCl treated-Endo (zacopride) group was (85.48±5.04) %, in U46619 treated–Endo (zacopride) group was (79.65 ± 3.51) %, compared to each corresponding vehicle group, allP<0.05. The inhibitor of IK1 channel, BaCl2 could signiifcantly reduce the vasodilatation effect of zacopride in KCl and U46619 pre-constricted coronary ring,P<0.05. However, the inhibitor of eNOS (L-NAME), the blocker of KCa channel (TEA), blocker of Kv channel (4-AP) and blocker of KATP channel (Glib) had no such signiifcant effects, allP>0.05.
Conclusion: Zacopride had vasodilatation effect on coronary arterial ring which was pre-constricted by KCl and U46619, which might be related to the channel of IK1.

BACKGROUND:Femoral offset reconstruction is significant for recovering strength of abductor and the balance of soft tissue tension surrounding hip joint, maintaining joint stabilization, restoring joint function, reducing limping after replacement, decreasing prosthetic abrasion, and the incidence of joint prosthesis dislocation.
OBJECTIVE:To discuss effect of femoral offset reconstruction on hip joint function in total hip arthroplasty.
METHODS:We comparatively analyzed 20 patients (20 hips) undergoing the modular prosthesis (S-ROM) total hip arthroplasty and 19 patients (20 hips) undergoing the one modular prosthesis (Corail) total hip arthroplasty at the same time. According to Harris hip score and radiography results, hip joint function and femoral offset reconstruction rate were comparatively studied in both groups.
RESULTS AND CONCLUSION:No infection, fracture, dislocation, deep venous thrombosis or neurovascular injury occurred in either group. Clinical fol ow-up results:In the modular prosthesis and one modular prosthesis groups, there was no significant difference in preoperative Harris hip score between the femoral offset reconstruction and non-reconstruction groups (P>0.05). At 12 months and the latest fol ow-up, the Harris hip score was higher in the patients with femoral offset reconstruction than those with femoral offset non-reconstruction (P<0.05). The range of abduction of hip joint was larger in patients with femoral offset reconstruction than those with femoral offset non-reconstruction (P<0.05). Radiographic fol ow-up results:significant differences in the rate of femoral offset reconstruction were detected between the modular prosthesis and one modular prosthesis groups (χ2=3.956, P<0.05). 39 (98%) femoral stems were in neutral position and one (2.5%) was in mild valgus. There was no significant difference in the abduction angle and the anteversion angle between patients with and without femoral offset reconstruction (P>0.05). These results indicated that functional recovery and the range of abduction were better in patients with femoral offset reconstruction than those without femoral offset reconstruction. Modular prosthesis has a high rate of femoral offset reconstruction.

Objective To compare the values of biochemistry, ultrasonography ( US) , computed tomography(CT) and proton magnetic resonance spectroscopy ('H MRS) in the quantitative diagnosis of fatty liver. Methods Forty-five healthy New Zealand rabbits were enrolled in the study. Hepatic steatosis models were established by giving high fat, high sugar diet with drinking water containing five percent ethanol. Eighteen variable indexes were measured by biochemical examination, US,CT and ' H MRS. ROC analysis and Z test were used to compare the diagnostic efficacy of different clinical examinations. Results Among eighteen variable indexes,serum TC,ultrasound attenuation coefficient,liver CT value and ' H MRS fat peak area had the highest degree of relationship by biochemical examination, US, CT, ' H MRS in diagnosis of fatty liver, correlation coefficients were 0.886,0.483, -0. 764, 0. 558, and areas under curve were 0. 981, 0. 581, 0. 810, 0. 713, respectively. There were significant differences in areas under curve between every two groups except 'H MRS fat peak area and ultrasound attenuation coefficient, liver CT value. Conclusions The diagnostic values of imaging modalities in the hepatic steatosis grade, their order is CT >'H MRS> US; Serum TC maybe have important diagnostic value in evaluating hepatic steatosis grade,this is very worth further studying.

OBJECTIVE: To characterize the hemodynamic changes of chronic congestive heart failure(CHF) model induced by rapid right ventricular pacing after myocardial infarction in awake Beagle dogs. METHODS: Five healthy adult male Beagle dogs were prepared for surgery. After the probes for measurement and the pacing leads were implanted, the left anterior descending artery was ligated during the surgery to induce myocardial infarction in the anterior wall of the left ventricle close to the apex. Six weeks after the surgery, rapid right ventricular pacing was initiated at the rate of 220 to 260 beats per minute for 4 weeks to induce CHF. Echocardiography was performed before the surgery. Both echocardiography and hemodynamic measurement were carried out before the rapid pacing and 4 weeks after the rapid pacing when the Beagle dogs were awake. RESULTS: There was no significant difference in left ventricle end diastolic diameter (LVEDD), left ventricle ejective fraction (LVEF), and fractional shortening (FS) between pre-operation and pre-pacing. LVEDD [(44.71+/-3.35) vs. (38.01+/-1.54) mm] and left ventricle end diastolic pressure (LVEDP) [(25.63+/-1.86) vs. (10.58+/-1.23) mmHg] at 4 weeks after pacing significantly increased compared with the pre-pacing data(P<0.05). LVEF, FS, and LV dp/dt max were significantly declined (P<0.01). CONCLUSION Left ventricle remodeling and hemodynamic changes in the Beagle dog CHF models produced by rapid right ventricular pacing after myocardial infarction are similar to the changes observed in CHF of human beings.
