Objective To observe the EGFR nuclear translocation in cervical carcinoma cell lines after irradiation and its possible role in radiation tolerance.Methods Western blotting was used to detect the nuclear EGFR and cytoplastic EGFR after irradiation.The effect of Cetuximab on expression of nuclear EGFR and survival fractions were investigated.Results After irradiation,compared with control group,the expression of nuclear EGFR protein increased in irradiated cervical carcinoma cell.Cetuximab inhibited the radiation-induced nuclear EGFR expression with decreased survival fractions.Conclusion Radiation could induce EGFR nuclear translocation in cervical carcinoma cell lines and nuclear EGFR might be correlated with radiation tolerance in Cervical carcinoma cell.

OBJECTIVETo investigate the value of technetium-99m methoxyisobutylisonitrile ((99)Tc(m)-MIBI) imaging in predicting the efficacy of neoadjuvant chemotherapy (NCT) and prognosis in patients with operable breast cancer.

METHODSSixty five patients with breast cancer underwent (99)Tc(m)-MIBI scintimammography before NCT, and static planar images were taken at 10 min and 180 min after scintimammography. The clearance rate was calculated in each patient, correlation between the clearance rate and efficacy of NCT, and the disease free survival rate were analyzed.

RESULTSThe mean clearance rate of 65 patients was (17.4 ± 6.8)%. The efficacy of NCT was 86.2% (CR 4 cases, PR 52 cases, SD 8 cases, and PD 1 case), and the mean clearance rate of patients with good response or poor response of chemotherapy were (15.5 ± 5.0)% and (29.2 ± 3.2)%, respectively. There was a significant difference between the two groups. The average disease free survival rate in the group with low clearance rate was (75.8%, P = 0.046), significantly higher than that in the group with high clearance rate (53.1%).

CONCLUSIONScintimammography of (99)Tc(m)-MIBI may be used to evaluate the efficacy and prognosis of NCT for patients with operable breast cancer.

Objective Color doppler ultrasonography of chronic Keshan disease (CKD) was evaluated to provide evidences for clinic diagnosis of the disease. Methods From September to Novermber 2009, according to "Diagnostic criteria of Keshan disease" (GB 17021-1997), 64 cases of CKD were randomly sampled from five Keshan diseased districts in Shandong province, Zoucheng, Sishui, Yishui, Wulian, Jvxian, and Pingyi as patient group. Thirty four healthy volunteers being checked up by Shandong Institute for Endemic Diseases Control and Research were put in control group. All the subjects were examined with Color doppler ultrasonography. The indexes of cardiac structure, left ventricular (LV) systolic function and LV diastolic function were measured.Results Left atrial internal diameter, LV end-diastolic internal diameter, LV end-systolic internal diameter, right ventricular diameter, aorta diameter, right atrial transverse diameter, right atrial long diameter and left ventricle mass of the patient group[(35.38 ± 6.89), (61.57 ± 8.61), (45.39 ± 10.29), (17.22 ± 3.79), (28.69 ± 2.81),(38.00 ± 6.05), (42.68 ± 8.65)mm, (283.22 ± 103.12)g] were higher than that of control group[(26.70 ± 3.27),(45.41 ± 4.93), (26.91 ± 4.35), (13.76 ± 2.27), (24.09 ± 2.89), (31.50 ± 3.32), (35.82 ± 3.14) mm, (156.03 ±39.86)g, t = 6.93, 10.09, 9.98, 4.87, 7.64, 5.81, 4.46, 6.90, all P＜ 0.05]. The LV ejection fraction and fractional shortening of the left ventricular of the patient group[(49.25 ± 14.33)%, (26.11 ± 9.17)%] were lower than that of control group[(73.88 ± 4.04)%, (42.88 ± 3.62)%, t = - 9.79, - 10.22, all P＜ 0.05]. Diffuse hypokinetic motion of the left ventricle reduced in 95% (61/64) of CKD patients, and 5% (3/64) of CKD patients had segmental LV dyskinesia. Seventy five per sent(48/64) of the patients accompanied with mitral regurgitation, and 39% (26/64) of these cases accompanied with tricuspid regurgitation. Meaningful Mitral or tricuspid regurgitation was not found out in control group. Conclusions The CKD patients' bore of atrio-ventricular cavity and LV mass are enlarged, and their motion of ventricle is reduced or partly reduced. They have poor heart function. Mitral regurgitation are more than tricuspid regurgitation. Color doppler Ultrasonography is important in diagnosis of chronic Keshan discase.

OBJECTIVETo investigate the effect of apatinib, a small-molecule vascular endothelial growth factor receptor-2 tyrosine kinase inhibitor, on the proliferation of human acute myeloid leukemia HL-60 cells and explore the possible mechanism.

METHODSMTT assay was used to assess the cytotoxicity of apatinib in HL-60 cells. The apoptosis and cell cycle changes of the cells in response to apatinib treatment were analyzed by flow cytometry, and Western blotting was used to assay P-Akt and P-Erk1/2 expressions in the cells.

RESULTSApatinib significantly inhibited the proliferation of HL-60 cells in vitro with an IC(50) of 4.96∓0.32 µmol/L. Apatinib treatment significantly increased the apoptotic rate of the cells in a dose-dependent manner, but produced no significant effect on the cell cycle (P>0.05). Western blotting showed that the expressions of P-Akt and P-Erk1/2 decreased in HL-60 cells after a 48-h apatinib treatment.

CONCLUSIONApatinib inhibits the proliferation of HL-60 cells by inducing cell apoptosis probably through the mechanism of inhibiting the expressions of the Akt/Erk1/2 signal transduction pathway.

Objective To report the outcome of emergency repair of severe complex defect in forearm by transplantation of free flap and simultaneous functional reconstruction.Methods From Mar.1994 to Aug.2003,4 cases with severe complex defect in forearm was repaired by transplantation of free skin flap, free skin flap combined with fibula flap,or fibula osteocutaneous flap in emergency.Simultaneously the flexion and extension function were repaired by muscle transfer and/or tendon grafting,tenonectomy.Results All the cases were successful.Follow-up period ranged from 1 to 3 years postoperatively.The blood-supply,tex- ture and elasticity of transferred flaps were excellent with good bone healing.Opposition of thumb with four fin- gers was good.Sensory recovery of the hand was satisfactory.Conclusion Transplantation of free flap com- bined with simultaneous functional reconstruction is an ideal method in emergency repair of severe complex de- fect in forearm.

OBJECTIVETo evaluate the effects of postburn dietary supplementation of arginine (Arg), omega-3 polyunsaturated fatty acid (omega-3PUFA) and glutamine (Glu) on the metabolism, immunology and wound healing in scalded rats.

METHODSThirty Sprague-Dawley (SD) rats inflicted with 30% total body surface area deep partial thickness scald on the back after the gastrostomy catheter was placed were employed as the model. The rats were randomly divided into A and B groups, and all of them received continuous isonitrogenous (25% protein, 12% fat, 63% carbohydrate), isocaloric (175 kcal/kg/day), and isovolemic intragastric tube feedings. The contents of Arg, omega-3PUFA, Glu in the dietary of B group were enriched. The parameters were measured on the 10th day after injury, including the response of spleen cells to ConA, the plasma levels of PGE(2), IL-2, albumin, transferrin, glucagons, cortisol in blood, the urinary content of vanillylmandelic acid (VAM) in 24-hour urine, the content of hydroxyproline, the ratio of type I to type III collagen in burn wounds, and the nitrogen content in the liver and in the jejunal mucosa, as well as the weight changes, skin delayed hypersensitivity test, and wound healing time.

RESULTSIt was revealed that the serum level of albumin, the nitrogen content in the liver and in the jejunal mucosa were obviously higher in B than those in A group. At the same time, there was no statistical difference in the plasma levels of cortisol and glucagons and urinary content of VAM between the two groups, nor in body weight changes. Meanwhile, the response of spleen cells to ConA and the skin delayed hypersensitivity induced by DNFB 14 days after injury in group B were also enhanced compared with those in group A. Although the expression of PGE2 from peritoneal macrophages was lower, the content of hydroxyproline from burn wounds in group B was significantly higher than that in group A, and the ratio of type l to type III collagen in group B was significantly lower than that in group A. Compared with group A, the wound healing time in group B was significantly shortened (P < 0.05).

CONCLUSIONThe low-fat and high-protein feeding diet with enriched arginine, omega-3 PUFA, glutamine could benefit the nutritional status after burn injury, thus improve the immunological function and promote wound healing.
