Background and purpose:A pre-surgery diagnosis of cervical invasion in endometrial cancer was usually determined by dilatations and curettage(D&C),so it could help in optimizing surgery,but the reliability of D&C still was controversial.This study was to compare MRI with D&C to estimate their accuracy for the diagnosis of cervical invasion in endometrial carcinoma respectively.Methods:34 endometrial cancer patients had been proved to have cervical invasion in endometrial cancer through examinations of either fractional dilatations and curettages(D&C),magnetic resonance imaging(MRI)before surgery or postoperative histopathologic examination.The results of D&C and MRI were compared with postoperative histopathologic examination,and the sensitivity,specificity were estimated for accuracy of cervical involvement in endometrial cancer.Results:21 of 34 patients were identified as having cervical invasion in endometrial cancer by histopathology after operation.D&C test matches 26.5% of them and MRI test matches 80%.The sensitivity was 35% vs.76.5% and the specificity 7.7% vs.100% for D&C and MRI methods respectively.All of them had significant statistical differences.Conclusions:MRI test is much better than D&C method for preoperative diagnosis of cervical invasion in endometrial carcinoma.

Objective To evaluate the correlation between the expression of C5b-9 and the gastric carcinoma.Methods In this study, the human gastric adenocarcinoma (HGAC)tissues (n =32 cases)from 32 patients were evaluated by immunohistochemistry and tissue chip.The result was analyzed and evaluated by Multinomial logistic regression and likelihood ratio.Results Multinomial logistic regression and likelihood ratio testing showed that over-expression of C5b-9 in HGAC tissue was significantly correlated with clinical stage (P =0.007) and tumor stage (P =0.005),but not with tumor metastasis,lymphoid nodal status,sex or age.Conclusion C5b-9 can be the criteria of di-agnosis and clinical staging for gastric adenocarcinoma,which may help in diagnosis and assessment disease severity of human gastric carcinoma.

Objective To investigate the protective effects of continuous norepinephrine infusion and its mechanism in early stage of lipopolysaccharide induced septic rats.Methods Forty SD rats were randomly divided into 5 groups (an external jugular vein catheterization was performed in every rat a day before intraperitoneal injection):saline control group (n =8),endotoxin group (n =8),low dose norepinephrine therepy group(n =8),middle dose norepinephrine therepy group (n =8),and high dose norepinephrine therepy group (n =8).Saline control group received intraperitoneal injection of 0.9％ saline 10 ml/kg,and then received an infusion of 0.9％ saline 1 ml/h.Endotoxin group animals were intraperitoneal injected with lipopolysaccharide 10 mg/kg,and then received an infusion of 0.9％ saline 1 ml/h.Therapy group animals received an infusion of norepinephrine solution 1 ml/h after being intraperitoneal injected LPS 10 mg/kg.The doses of norepinephrine were 0.06,0.3,0.6 μg/(kg· min) respectively.Blood samples were taken 2 h and 6 h later and the levels of serum TNF-α、IL-1β and IL-10 were detected by enzyme-linked immunoadsorbent assay.The membrane potential and three tricarboxylic acid cycle key enzyme activity [isocitrate dehydrogenase(IDH) and pyruvate dehydrogenase (PDH) activity] of isolated liver mitochondrion were detected 24 h later,and the morphologic changes of mitochondria in liver were observed by electronic microscopy.Results In endotoxin group,the levels of serum TNF-α JL-1 β and IL-10 all increased significantly(P ＜ 0.05) and liver mitochondrial membrane potential,PDH and IDH activity decreased significantly compared with control group(P ＜0.05,P ＜0.01).In the middle dose of norepinephrine therepy group,the levels of serum TNF-α and IL-1β all increased significantly (P ＜ 0.05,P ＜ 0.01),the level of serum IL-10 decreased significantly compared with endotoxin group (P ＜ 0.05) ; In the high dose norepinephrine therepy group,the liver mitochondrial membrane potential,PDH and IDH activity increased significantly compared with endotoxin group (P ＜ 0.05).The mitochondrial ultrastructural changes in every group were not obviously.Conclusion In the early stage of septic rats,reversible liver mitochondrion injury can be observed.Norepinephrine infusion can protect early septic rats through attenuating inflammatory reaction and enhancing tricarboxylic acid cycle key enzyme activity and mitochondrial membrane potential level.

Objective To investigate the impact of high altitude on human gastric mucosa and its underlying mechanisms. Methods Twenty-five native Tibetans with chronic mountain sickness CMS residing at high altitude (4500 m) were examined for ultrastrueture and pathological changes of gastric mucosa. The other 25 native Tibetans residing at low altitude (＜2000 m) were served as control.The expression of hypoxia-inducible factor (HIF)-1α in human gastric mucosa was detected with immunohistochemistry. Results The color of gastric mucosa presented dark in patients with CMS.The histopathological examination showed significant differecnce in incidence of cnronc body gastritis and atrophic gastritis between CMS group and control group (P＜0. 05). The transmission electronic microscopy revealed that the epithlieal cells of gastric mucosa were impared in CMS group compared to control group. The expression of HIF-1α protein was increased in CMS group in comparison of control group (102.94± 34.04 vs 14.04 ± 6.53, P＜0.05). Conclusions The high altitude may involve in damage of gastric mucosa and the up-regulation of HIF-1α protein may involve in its mechanism.

The human bone morphogenetic protein 7 (hBMP 7) gene was reconstructed in retroviral vector and transferred into incasing cells PT67 by liposome mediated method.The clones of the cells transferred with BMP 7 were selected by G418, and targeted rabbit bone marrow stem cells were infected with the virus granules which secreted from PT67 cells and also selected by G418. The mRNA and protein of BMP 7 gene in transferred cells were analyzed with hybridization in situ and immunohistochemistry. BMP 7 retrovirus vetor was successfully reconstructed. Cells transferred by PLNCX 2 hBMP 7 expressed abundant human BMP 7 mRNA and protein in the cytoplasm. However positive findings were not found in those cells that were not transferred. It may be used to increase the osteogenic capability of BMSc in the study of bone tissue engineering.

PurposeTo analyze the urinary stone chemical composition using dual source CT (DSCT) dual energy imaging.Materials and MethodsNinety-seven stone samples with known chemical composition were placed in fresh swine kidneys and examined with DSCT dual energy scan, including 55 calcium oxalate stones, 13 hydroxyapatite stones, 9 uric acid stones, 4 cystine stones, 2 struvite stones and 14 mixed stones. The mean attenuation values and dual energy index (DEI) were measured at 80 kV and 140 kV. The stone composition was analyzed to determine the sensitivity, specificity and accuracy.ResultsDual energy analysis showed 59 calcium oxalate stones, 11 hydroxyapatite stones, 9 uric acid stones, 4 cystine stones and 14 mixed stones. 2 hydroxyapatite stones were erroneously marked as calcium oxalate stones and 2 struvite stones as calcium oxalate stones. The accuracy was 95.88% (93/97). The difference CT value at 80 kV and 140 kV and DEI value were statistically significant (P<0.05). The sensitivity for detecting calcium oxalate stones, hydroxyapatite stones, uric acid stones and cysteine stones were 100.00%, 84.60%, 100.00% and 100.00%, respectively; with specificity of 85.70%, 100.00%, 100.00% and 100.00%, respectively; and the accuracy were 95.18%, 97.59%, 100.00% and 100.00%, respectively.ConclusionDSCT dual energy imaging accurately analyzes the chemical composition of urinary stone in vitro, which provides important clinical value in analyzing the urinary stonesin vivo.

Objective To investigate the relationship between methylenetetrahydrofotate reductase (MTHFR)C677T polymorphisms and H-type hypertension and increased plasma homocysteine (Hcy) levels. Methods From September 2013 to June 2014,4 012 permanent residents aged ≤30 year from 12 natural villages or communities in 6 regions of Hunan province were extracted according to the cluster random sampling method. Using computer random number table,571 residents were randomly selected as the research objects. According to the blood pressure and Hcy levels,571 residents were divided into 3 groups:a common hypertension group (n = 190),an H-type hypertension group (n = 94),and a normal blood pressure group (n = 287 ). Amplification refractory mutation system-polymerase chain reaction (ARMS-PCR)method was used to detect the MTHFR C677T polymorphisms in all the research objects and the penotyping was performed. Hcy levels were detected at the same time. Results There were significant differences in recessive model (CC + CT,TT)genotype frequencies among the H-type hypertension group (n = 66[70. 2%],n = 28[29. 8%]),common hypertension group (n = 156[82. 1%],n = 34[17. 9%]), and normal blood pressure group (n = 235[81. 9%],n = 52[18. 1%])(χ2 = 6. 797,P = 0. 033),and there were no significant differences in CC,CT,and TT genotype frequencies among the 3 groups (P >0. 05). In the recessive model,there were significant differences in TT genotype frequencies between the H-type hypertension group and the normal blood pressure group or the common hypertension group (χ2 = 5. 812,P = 0. 016;χ2 = 5. 212,P = 0. 022). There was no significant difference in TT genotype frequencies between the common hypertension group and the normal blood pressure group (P > 0. 05). The CC + CT and TT genotype Hcy levels of the MTHFR C677T recessive model in the H-type hypertension group were 17. 1 ±1. 6 and 19. 0 ±2. 9 μmol/ L respectively. There was significant difference between the genotypes (t = - 3. 115,P = 0. 004). The logistic regression analysis of MTHFR C677T recessive model genotype showed that after adjusting for sex and age,the residents with recessive model TT genotype had higher risk of H-type hypertension (OR,1. 946,95% CI 1. 172 -3. 232,P = 0. 01). Conclusion The TT MTHFR C677T gene mutation in this population may be an important genetic factor for the increased Hcy levels and the onset of H-type hypertension.
