Objective To evaluate four tumor markers of insulin-like growth factor 1((IGF-1), CEA, cytokeratin fragment antigen 21-1 (CYFRA21-1), neuron-specific enolase (NSE) for the diagnosis and prediction of treatment response in human lung cancer. Methods Serum samples were taken from three groups: 91 patients with lung cancer, 30 healthy adults and 15 patients with benign pulmonary diseases. Serum IGF-1 was assayed by radioimmunoassay and CEA, CYFRA21-1, and NSE by electrochemiluminescence immunoassay. The differences among the three groups were determined by Kruskal-Wallis one-way analysis of variance (ANOVA) and with Mann-Whitney rank-sum test. Diagnostic efficacy was evaluated by ROC curves. Results The four serum tumor marker levels were significantly higher in lung cancer group, as compared with the benign and the healthy (IGF-1:χ2=26.95,P<0.001, CEA:χ2=49.11,P<0.001; CYFRA21-1:χ2=40.63,P<0.001; NSE:χ2=14.76;P<0.001). The diagnostic sensitivities of IGF-1, CEA, CYFRA21-1 and NSE was 75.6% (34/45), 53.3% (24/45), 66.7% (30/45) and 42.2% (19/45) respectively for lung cancer. The diagnostic sensitivity of IGF-1 combined with CYFRA21-1 was 95.5 %( 43/45) and that of IGF-1 combined with CEA and CYFRA21-1was 97.8%(44/45). Only IGF-1 and CYFRA21-1 showed significant changes before and after treatment (IGF-1: χ2=5.99,P=0.014; CYFRA21-1:χ2=4.99, P=0.025) in cancer group. Conclusions Serum IGF-1, CEA, CYFRA21-1 and NSE are all valuable for lung cancer diagnosis and the combination of those parameters can enhance the diagnostic efficiency. Serum IGF-1 and CYFRA21-1 may also be useful for evaluating the treatment response in lung cancer.

Objective To evaluate the effect of anisodamine on endoplasmic reticulum stress during acute kidney injury (AKI) in rats.Methods Forty-two nale Sprague-Dawley rats,weighing 200-220 g,were randomly divided into 3 groups:control group (group C,n =6),AKI group (n =18) and anisodamine group (group AD,n =18).AKI was induced by intramuscular injection of 50% (v/v) glycerol 10 ml/kg into bilateral hind limbs in groups AKI and AD.In addition,anisodamine 10 mg/kg was injected intraperitoneally 20 min before intramuscular injection of glycerol in group AD.In group C the rats received intramuscular injection of normal saline 10 ml/kg into bilateral hind limbs.Six rats were chosen immediately after injection of normal saline in group C or at 1,6 and 24 h after glycerol injection in groups AKI and AD and then anethetized with intraperitoneal pentobarbital.The animals were sacrificed and kidney specimens were obtained and cut into sections which were stained with hematoxylin and eosin for pathological examination.The pathological changes of the renal tubules were scored.The expression of glucose-regulated protein 78 (GRP78) and oxygen-regulated protein 150 (ORP150) in renal tissues was determined by immuno-histochemistry and Western blot.Results Compared with group C,the pathological scores were significantly increased and the expression of GRP78 and ORP150 was up-regulated at all time points in groups AKI and AD (P < 0.01).Compared with group AKI,the pathological scores were significantly decreased and the expression of GRP78 and ORP150 was down-regulated at all time points in group AD (P < 0.05 or 0.01).Conclusion Anisodamine can ameliorate AKI through inhibiting endoplasmic reticulum stress in renal tubular epithelial cells and decreasing endoplasmic reticulum stress-induced cell apoptosis in rats.

Objective To investigate the depressing effect of antigene peptide nucleic acid (AGPNA)on the k-ras gene expression of human pancreatic cancer Patu8988 cells, the inducing apoptosis effect on Patu8988 cells, and the biodistribution characteristics in nude mice bearing xenografts using 188Re-k-ras-AGPNA.Methods The expression level of k-ras mRNA and the expression ratio of k-ras protein in Patu8988 cells transfected with AGPNA was measured by RT-PCR and flow cytometry ,respectively. The degree of cellular apoptosis 3 to 5 d after treating Patu8988 cells with 188Re-k-ras-AGPNA or 188ReO4- was determined by flow cytometry. For biodistribution study, 58 nude mice bearing Patu8988 cell xenografts were divided into two groups: intratumoral injection of 188Re-k-ras-AGPNA (Group A) and 188ReO4- (Group B). At different time points, the mice were sacrificed and organs of interest were excised, weighted and counted by a gamma counter. The organ uptake was calculated as a % ID/g and the absorbed doses of organs were calculated. One-way analysis of variance was used. Results After transfected with 1 nmol/ml AGPNA, the k-ras mRNA gray scale ratio and the expression ratio of k-ras protein were 1.00 ± 0.39 and (15.05 ± 5.07)%, respectively. They were significantly lower than those of the control group with 1.86 ± 0.07 and (24. 38 ± 5.40) % (F = 2. 545, 5. 327, P<0. 05). At 4 and 5 d after treatment in Group A, float cells' apoptosis ratios were (26.30 ± 7.45) % and (27.90 ± 10. 38) %, respectively. Tumors were the major distribution site in Group A with uptake of (37.47 ±21.31), (35.96 ±7.80) and (15.46 ±4.93) %lD/g at 1 h, 1 d and 7 d after intra-tumor injection, respectively. The absorbed dose of tumor was 15 569 mGy/MBq. Condusions Transfection with k-ras-AGPNA on Patu8988 cells may inhibit k-ras expression at mRNA and protein expression level, and 188Re-k-ras-AGPNA can induce apoptosis of Patu8988 cells.Tumor is the major distribution site in nude mice bearing human pancreatic cancer xenografts after intratumoral injection of 188Re-k-ras-AGPNA.

Objective To investigate the feasibility and safety of helix hydro-jet lithotrity in treatment of calculus of intrahepatic duct and to establish its basic parameters.Methods The parameter of hydro-jet Was set at different levels of pressure(5000-9000 kPa)and different nozzle directions,and the effect of different parameter wag observed and analyzed in three groups.including 32 ex vivo intrahapatic gallstones.thirty-two ex vivo swine bile ducts and 31 ex vivo bile ducts obtained from patients with hepatolithiasis.Results Lithotrity was successful in all groups with a jet pressure of 5000-9000 kPa.The multiple regression analysis showed that the time of procedure depended linearly on the minimal stone diameter,stone weight andjet pressure.The time of procedure and the time needed to damage the bile duct decreased with the increase in jet pressure.At same jet pressure,the smaller the angle between nozzle and bile duct,the longer the time needed to cause damage in bile duct.The technique was successfully performed in 60 patients,with no severe complications,including bile duct injury.Conclusion It is feasible to treat hepatolithiasis with hydro-jet lithotrity.The most optimal operation condition was hydro-jet pressure of 6000-7500 kPa and frequency of 1 Hz.

Objective To explore the effect of caspase-9 inhibitor on low fetal bovine serum ( FBS)-induced apop-tosis in cartilage endplate chondrocytes in SD rat vertebrae.Methods Disc cartilage endplates were obtained from 3-month old SD rats and subjected to sequential digestion to harvest chondrocytes for primary culture, and apoptosis was in-duced by 1%FBS for 48 hours.Three groups of chondrocytes were treated by 1% FBS, caspase-9 inhibitor ( Z-LEHD-FMK) and DMSO, respectively.After 48 hours, apoptosis was detected by DAPI staining and flow cytometry.The expres-sion of procaspase-9, active caspase-9 and active caspase-3 was monitored by Western blot.Results Compared with the 1%FBS group (40.8 ±0.84)%and DMSO group (40.2 ±1.56)%, the apoptosis rate of the caspase-9 inhibitor group (26.3 ±2.56)% was significantly lower (P<0.05).The expressions of active caspase-9 and active caspase-3 in the caspase-9 inhibitor group were significantly lower than those in the other two groups (P<0.05).Conclusions Caspase-9 inhibitor can inhibit low FBS-induced apoptosis in cartilage endplate chondrocytes of rat vertebrae, and might become a new drug for the treatment of disc degeneration.
