Objective To compare the diagnostic value of 3.0T and 1.5T magnetic resonance diffusion weighted imaging (DWI) in lymph node metastasis of gastric cancer. Methods Preoperative magnetic resonance examination was performed on 50 patients with gastric cancer by using Siemens 1.5T and 3.0T superconducting magnetic resonance imaging system, and the outcomes were compared with postoperative pathological results. The sensitivity, specificity and accuracy of the diagnosis in lymph node metastasis of gastric cancer were analyzed statistically. The apparent diffusion coefficient (ADC) values of lymph nodes were also evaluated for 1.5T and 3.0T magnetic resonance DWI. Results The sensitivity, specificity and accuracy of the diagnosis on lymph node metastasis of gastric cancer by 1.5T magnetic resonance DWI were 79.4 %, 81.4%and 80.0%, respectively, and the corresponding percentages of 3.0T magnetic resonance DWI were 84.6%, 79.7%and 83.1%. The accuracy rate of 3.0T magnetic resonance DWI was slightly higher than that of 1.5T in the diagnosis of lymph node metastasis of gastric cancer (χ2=5.451, P=0.020), but there were no significant differences in the sensitivity and specificity between the two groups (both P> 0.05). The accuracy rate of 1.5T magnetic resonance DWI in the diagnosis of lymph node metastasis of gastric cancer was less effective than that of the pathological diagnosis (χ2=7.410, P=0.007), but there was no significant difference between 3.0T magnetic resonance DWI and pathological diagnosis (χ2=2.450, P=0.120). The mean ADC values of metastatic and non-metastatic lymph nodes detected by 1.5T magnetic resonance DWI were (1.036 ±0.203) × 10-3 mm2/s and (1.476 ± 0.215) × 10-3 mm2/s (t= 6.813, P< 0.001), meanwhile, the corresponding values detected by 3.0T magnetic resonance DWI were (1.154 ± 0.183) × 10-3 mm2/s and (1.502 ± 0.264) × 10-3 mm2/s (t= 5.991, P< 0.001). The coincidence of the two methods for ADC value was favorable. Conclusions The diagnostic effect of 3.0T magnetic resonance DWI on lymph node metastasis of gastric cancer is better than that of 1.5T. ADC value provides a reliable imaging quantitative indicator for the determination of metastatic lymph nodes in gastric cancer, which plays a significant role in the clinical treatment options and prognosis of patients.

BACKGROUND: Diphosphonate has a predominant therapeutic effect in the prevention and treatment of postmenopausal osteoporosis. Ibandronate, as a new-type diphosphonate preparation, is gradually becoming a study hotspot.OBJECTIVE: This study is to investigate the efficiency of ibandronate in interfering postmenopausal osteoposis by observing bone mass loss related indexes in ovariectomized rats, and made a comparison with nilestriol.DESIGN: A completely randomized grouping, and controlled animal experiment.SETTING: Study Room for Bone metabolism, Fudan University Medical College.MATERIALS: Forty SD female rats, aged 10-12 months, were involved in this study. Ibandronate was provided by the State Key Laboratory of Jiangsu Institute of Atomic Medicine. Nilestriol was produced in the Shanghai 12th Pharmaceutical Factory.METHODS: This experiment was carried out in the Study Room for Bone Metabolism, Institute of Radiation Medicine,Shanghai Medical University between August 1996 and June 1998. The rats were divided into 4 groups by a lot, 10 rats in each: sham-operation group, ovariectomized group, ovariectomized+ibandronate group and ovariectomized +nilestriol group. In the sham-operation group, only small pieces of adipose tissue around the ovary were resected from the rats.Three months after operation, each rat was intragastrically administrated with 1 mL normal saline; In the ovariectomized group, ovariectomized+ibandronate group and ovariectomized +nilestriol group, each rat was subjected to bilateral ovariectomy, and 3 months later, they were intragastrically administrated with normal saline, ibandronate water solution [0.5 mg/( kg·d)] and nilestriol suspension [1 mg/(kg· time)] respectively. Each rat in the latter three groups was administrated for 90 days, twice in the first week, and then once a week.MAIN OUTCOME MEASURES: Left femur was taken out, and its dry weight and ash weight were measured. Calcium content of bone was determined with an atomic absorption spectrophotometer, bone density of the whole body with a bone density apparatus, the bone density at the juncture of 1/2 right femoral bone length with a single photon bone density apparatus, and femoral anti-bending force was determined with a universal testing machine. Alkaline phosphatase were determined by dynamical method with an automatic biochemistry analyzer, urine calcium by EDTA titration method, urine creatinine by picric kinetic method, and urinary hydroxyproline by modified proline assay.Trabecular area was calculated.RESULTS: Forty rats were involved in the final analysis. ① Bone dry weight, bone ash weight and bone calcium content in the ovariectomized group were significantly lower than those in the other 3 groups, respectively (t =13.58-52.98, P <0.05). ② Femoral bone density and bone density of the whole body of rats in the ovariectomized group were significantly lower than those in the other 3 groups (t =3.31-5.61, P<0.05), while anti-bending force was close between ovariectomized group and the other 3 groups (P>0.05). ③ The ratio of urine calcium to urine creatinine was significantly lower in the ovariectomized+ibandronate group and ovariectomized +nilestriol group than in the ovariectomized group (t =4.04, 3.30, P<0.05). No significant difference in the alkaline phosphatase and ratio of urinary hydroxyproline to urinary creatinine existed among the groups (P > 0.05). ④Trabecular area of vertebrae in the ovariectomized group was significantly smaller than that in the other 3 groups (t =2.22,2.41,3.45,P < 0.05), while the trabecular area of tibia in the ovariectomized group was only smaller than that in the ovariectomized +nilestriol group (t =2.45, P< 0.05).CONCLUSION: Osteoporosis apPears obviously in the SD rats 3 months after ovariectomy. Ibandronate has obviously inhibitory effects on the bone mass loss of rats with postmenopausal osteoposis, and it is equivalent to nilestriol in inhibitory effect.

Objective To identify the potential prognostic biomarkers of the immune-related genes signature for patients with hepatocellular carcinoma (HCC). Methods Original HCC data were downloaded from TCGA, and the immune activity of each sample was calculated by ssGSEA. HCC samples were divided into high and low immune cell infiltration groups by "GSVA" package and "hclust" package. The ESTIMATE algorithm scored the tumor microenvironment in each HCC sample. The "limma" package and Venn diagram identified effective immune-related genes. Univariate Cox, Lasso regression and multivariate Cox regression analyses were used to explore key genes. The "rms" package was used to create nomograms and draw calibration curves. Results Compared with the high immune cell infiltration group, the tumor purity of the samples in the low immune cell infiltration group was higher, the immune score, ESTIMATE score and stromal score were lower. In the high immune cell infiltration group, the immune components were more abundant, and the expression levels of TIGIT, PD-L1, PD-1, LAG3, TIM-3, CTLA4 and HLA family were higher. Multivariate Cox regression analysis showed that four immune-related genes (S100A9, HMOX1, IL18RAP and FCER1G) were used to construct the prognosis model. Compared with other clinical features, the risk score of this prognostic model was recognized as an independent prognostic factor. Conclusion This study identified the immune-related core genes which may be used in targeted therapy and immunotherapy of HCC.
