Objective The aims of this study were to investigate the prognostic value of CEA and CA19-9 expression in advanced gastric cancer and the prognostic factors of advanced gastric cancer.Methods A total of 255 patients with advanced gastric cancer who underwent radical R0 radical surgery were enrolled in the Department of Gastrointestinal Surgery,Harbin Medical University Cancer Hospital from January 2010 to December 2010,and were divided into group A(CEA<2.19ng/mL and CA19-9<10.78U/mL),group B(CEA≥2.19ng/mL or CA19-9≥10.78U/mL)and group C(CEA≥2.19ng/mL and CA19-9≥10.78U/mL).These groups were analyzed the differences in gastric cancer patients with clinical pathology and survival,and prognostic factors of patients with advanced gastric cancer factors.Results There were statistically significant differences in clinical N staging,clinical TNM staging and pathological TNM staging in three groups of patients with advanced gastric cancer(P<0.05).There was no significant difference in the median survival time in three groups of patients with advanced gastric cancer(P>0.05).The 1-year,3-year and 5-year survival rates of group A were higher than those of group B and group C(P>0.05).The factors affecting the prognosis of gastric cancer included the degree of tumor differentiation,pathological T staging,pathological TNM staging,the total number of lymph nodes,the number of positive lymph nodes and lymph node metastasis.Conclusion Combined detection of CEA and CA19-9 expression indicates a certain reference value for prognosis of gastric cancer.

Objective To investigate the effectiveness of arthroscopic reduction and percutaneous fixation (ARPF) for the treatment of tibial plateau fractures. Methods Seventeen cases of tibial plateau fractures from April 1999 to June 2002 were reviewed. The fractured tibial plateau was reconstructed by “drag-and-draw” reduction and iliac crest bone graft under arthroscope. And percutaneous cancellous bone screw fixation was conducted. Results Clinical bone union was achieved in all the patients at the third postoperative month. No infection or severe osteoarthritis occurred. Conclusions ARPF for tibial plateau fractures has advantages of reduction under direct view, reliable fixation and facilitation for early activities.

BACKGROUND: Most of the literatures only reported that there is a great difference between diabetics who have a high 24-hour urinary albumin excretion rate and those without renal damage, but there is no obvious difference between cases of microalbuminuria and those without renal damage.OBJECTIVE: To probe into the relationship between diabetic nephropathy and osteoporosis.DESIGN: A case-control study.SETTING: Department of Endocrinology, West China Hospital of Sichuan University.PARTICIPANTS: According to the diagnostic standard set by the American Diabetes Association in 1997 (fasting blood glucose ≥ 7 mmol/L,postprandial blood glucose ≥ 11.1 mmol/L), 96 diabetic patients were selected, including 56 males ＜ 60 years old and 40 females who had not entered the menopausal period, excluding the influence of age and osteoporosis caused by menopause. The average age of the subjects was (48.7±10.5)years, their duration were from one month to twenty-one years with the aver age of (7.85±2.56) years, and their general information had no significant differences.METHODS: According to the urine albumine excretion rate and renal function, the patients were divided into four groups: normal albuminuria group (n=48), microalbuminuria group (n=28), macroalbuminuria group (n=15), renal failure group (n=5). The bone mineral densities of lumbar spines (L2-4), femoral neck, Ward's triangle and trochanter were detected with Dual energy X-ray absorptiometry, and then the fasting blood glucose,2-hour postprandial blood glucose, glycosylated hemoglobin A, alkaline phosphatase, calcium, phosphorus, blood urea nitrogen, creatinine and urine albumine excretion rate were compared between the patients with and without osteoporosis.MAIN OUTCOME MEASURES: The fasting blood glucose, 2-hour postprandial blood glucose, glycosylated hemoglobin A, alkaline phosphatase, calcium, phosphorus, blood urea nitrogen, creatinine and urine albumine excretion rate, as well as the bone mineral density, were observed in all the patients.RESULTS: The L2-3 bone mineral density in the macroalbuminuria group was significantly different from that in the microalbuminuria group (P ＜ 0.05). The proximal femur bone mineral density in the microalbuminuria group was significantly different from that in the normal albuminuria group (P ＜ 0.05). The bone mineral densities of proximal femur and lumbar spine in the renal failure group were significantly decreased as compared with those in the other groups (P ＜ 0.01). The disease course,glycosylated hemoglobin A, alkaline phosphatase and body mass index were significantly different between the patients with and without osteoporosis (P ＜ 0.05).CONCLUSION: The incidence rate of osteoporosis is increased with the aggravation of nephropathy, and diabetic nephropathy may be closely correlated with the decrease of bone mineral density and the occurrence of osteoporosis.

OBJECTIVE:To study the protective effect of tanshinoneⅡA(TSⅡA)sulfonate injection against vancomycin(VAN)-induced renal injury model rats and its mechanism. METHODS:72 rats were randomly divided into blank group,model group, positive control group(amifostine,1 mg/kg)and TSⅡA sulfonate injection low-dose,medium-dose and high-dose groups(15,30, 60 μg/kg),with 12 rats in each group. Except for blank group,those groups were given VAN(200 mg/kg)intravenously via tail vein to induce renal injury rat model;after modeling,each drug group was given relevant medicine intraperitoneally once a day, and blank group and model group were given normal saline intragastrically for consecutive 10 days. The levels of 24 h protein, NAG and KIM-1 in urine were determined,and those of Cys C,Scr and BUN in serum and those of SOD,MDA,GSH-Px and NO in renal homogenate were also determined;the pathological change of renal tissue was observed. RESULTS:Compared with blank group,the levels of Cys C,Scr and BUN in serum,those of 24 h protein,NAG and KIM-1 in urine and those of MDA and NO in renal tissue increased significantly in model group,while the levels of SOD and GSH-Px decreased significantly(P<0.01);the pathological slice indicated that model group suffered from renal injury such as kidney tubules albuminoid degeneration,brush border abscission,renal tubular epithelial cell disintegration and abscission. Compared with model group,the levels of Cys C,Scr and BUN in serum,those of 24 h protein,NAG and KIM-1 in urine and those of MDA and NO in renal tissue decreased signifi-cantly in treatment groups,while the levels of SOD and GSH-Px in renal tissue increased significantly(P<0.05 or P<0.01);path-ological changes of renal tissue were relieved significantly. CONCLUSIONS:TSⅡ A sulfonate injection can effectively relieve VAN-induced renal injury in rats,and its mechanism may be associated with inhibiting the oxidative reaction of rats in vivo.

OBJECTIVE:To develop and improve the quality standard for Kanggu zengsheng tablet. METHODS:TLC was used for the qualitative identification of Drynaria fortunei,Epimedii Folium and Spatholobus suberectus;HPLC was used for the contents determination of icariin and acteoside:the column was Diamonsil C18 with mobile phase of acetonitrile-0.1% formic acid solution (gradient elution) at a flow rate of 1.0 mL/min;detection wavelength was 270 nm for icariin and 334 nm for acteoside, Cdumn temperature was 25 ℃,and the injection volume was 10 μL. RESULTS:The TLC spots of D. fortunei,Epimedii Folium and S. suberectus were clear and well separated,negative control without interference. The linear range was 0.0188-1.88 μg for ac-teoside(r=0.9999)and 0.107-2.14 μg for icariin(r=0.9999);RSDs of precision,stability and reproducibility tests were lower than 2.0%;recoveries were 100.2%-105.0%(RSD=1.6%,n=9) and 96.2%-99.5%(RSD=1.4%,n=9). CONCLUSIONS:The improved standard can more effectively control the quality of Kanggu zengsheng tablet.
