Spinal giant cell tumor of bone (GCTB) is a kind of primary benign bone tumors in the spine. It is rich in blood supply,aggressive,and easily recurring and lung metastasizing. So the benign GCTBs of the spine remains a challenge to treat.This article reviews the therapeutic methods in spinal GCTBs,including surgery,radiation therapy,arterial embolization. The treatment for the tumor with lung metastasis is also covered in this review. It is established that En bloc resection with wide margins is the most effective method to spinal GCTBs. To eliminate the residual tumor cells,adjuvant radiation should be done when complete resection is not available. Arterial embolization can be used to treat the huge sacral GCTBs.For those with lung metatasis,they can be controlled by lobectomy and /or chemotherapy.

Objective To investigate the incidence of neonatal intrahepatic cholestasis caused by citrin deficiency (NICCD)in neonates with idiopathic neonatal cholestasis (INC)in Nanjing,China,SLC25A13 gene mutations in these neonates,and clinical features.Methods A total of 152 neonates with INC,who were admitted to the Affiliated Nanjing Children's Hospital of Nanjing Medical University from Sep-tember 2009 to August 2013,underwent gene analysis for detecting SLC25A13 gene mutations.The neonates were divided into NICCD group,who had been diagnosed definitely,and INC group at a ratio of 1∶2,considering the age and gender.Several biochemical indices were compared between the two groups.Comparison of continuous data between the two groups was made by Mann-Whitney U test after Bonferroni correction.Results There were 21 confirmed cases of NICCD (21/152,13.82%)among the 152 neonates with INC;five types of SLC25A13 mutations were identified in the 21 neonates with NICCD,including 851_854del (27/42,64.29%),IVS6+5 G→A (7/42, 16.67%),1638ins23 (5/42,11.90%),IVS11 +1 G→A (2/42,4.76%),and Q259X (1/42,2.38%).The alanine aminotransferase (ALT)level,aspartate aminotransferase (AST)level,bile acid concentration,albumin level,fasting blood glucose,blood ammonia,and prothrombin time for the NICCD group were 39.42 ±23.40 U/L,124.85 ±92.65 U/L,142.43 ±24.34μmol/L,30.66 ±2.70 g/L,2.79 ± 0.54 mmol/L,117.57 ±27.88 μmol/L,and 14.03 ±2.79 s,respectively,versus 136.02 ±113.67 U/L,226.12 ±129.26 U/L,80.47 ± 31.53 μmol/L,36.87 ±4.96 g/L,3.14 ±0.45 mmol/L,76.43 ±20.80 μmol/L,and 11.40 ±1.55 s for the INC group.The NICCD group had significantly lower ALT and AST levels than the INC group (Z=-5.02,P=0.000;Z=-3.66,P=0.000);the NICCD group had a significantly higher bile acid concentration than the INC group (Z=-5.58,P=0.000);the NICCD group had significantly lower albumin level and fasting blood glucose than the INC group (Z=-4.52,P=0.000;Z=-2.56,P=0.010);the NICCD group had a significantly higher blood ammonia level than the INC group (Z=-4.75,P=0.000);the NICCD group had a significantly longer prothrombin time than the INC group (Z=-4.10,P=0.000).Conclusion Citrin deficiency due to SLC25A13 gene mutations is an im-portant cause of INC in Nanjing.The three most common mutations are 851_854del,IVS6+5 G>A,and 1638_1660dup23,which account for 92.86% of the SLC25A13 gene mutations.More attention should be paid to clinical analysis and detection of SLC25A13 gene mutations to confirm the diagnosis of NICCD.

A moderately thermoacidophilic iron-oxidizing bacterium,designated as strain MLY,was isolated from a coal spoil heap in China.The optimum of temperature for growth is 50℃～54℃.The optimum of pH is 1.2～1.4.The strain MLY is facultative autotroph and grows heterotrophically on yeast extract.It is able to oxidize ferrous iron(Fe 2+ ),pyrite(FeS 2),and elemental sulfur(S 0) autotrophically and mixotrophically in the presence of yeast extract.Autotrophic oxidation of elemental sulfur is relative weak.The comparison of ferrous iron and pyrite oxidation between strain MLY and A10 Thiobacillus ferrooxidans,strain indicated that MLY is one time faster than A10.

Objective To evaluate the significance of suPAR,SCC-Ag in plasma and HPV16,18 in cervical secretion for monitoring pathogenetic condition and prognosis in patients with cervical cancer.Methods 206 cervical cancer patients blood and cervical secretion were collected.Plasma level of suPAR and SCC-Ag were measured by enzyme linked immunosorbent assay (ELISA) in health women and patients with cervical cancer.The expression of HPV16,18 of cervical secretion in control group and patients with cervical cancer were detected by fluorescence quantitative PCR.The correlations of the three indexes were analyzed.Results The plasma level of suPAR and SCC-Ag,the expression of HPV16,18 of cervical secretion in cervical cancer patients were obviously higher than those in health controls with statistical significance ((1.072 5±0.305 2) ng/ml vs (0.501 7±0.179 3) ng/ml,(0.980 6±0.162 7) μg/ml vs (0.261 4± 0.006 3) μg/ml and 53.89 ％ (90/167),46.15 ％ (18/39) vs 6.67 ％ (4/60),P ＜ 0.05).There was a positive correlation between plasma suPAR level and SCC-Ag level in invasive carcinoma of cervix patients (r =0.564,P ＜ 0.05).The plasma level of suPAR between in HPV16,18 positive group and in HPV16,18 negative group did not show difference (P ＞ 0.05).Conclusions In invasive carcinoma of cervix patients,there is a positive correlation between plasma suPAR level and SCC-Ag level.But it's not yet to conclude that plasma suPAR level of cervix invasive carcinoma patients is related to infection of HPV16,18.

Objective The aim of the study was to investigate the diabetic neuro-degeneration and its changes in neuroreaction to myocardial ischemia and reperfusion,by evaluation of the altera-tion of noxious thermal threshold and expression of substance P (SP),calcitonin gene related peptide (CGRP)in dorsal root ganglia in upper thoracic segments (T1-5 )in diabetic rats.Methods Thirty two male Sprague-Dawley rats,weighing 180-200g,were randomly divided into control group (group C)and diabetic group (group DM),1 6 rats in each group.rats in DM group were fed with high sug-ar-fat diet for 14 weeks and were given streptozotocin (STZ,35 mg/mg,i.p.)at the end of the 4 th week,to set up diabetes experimental model.The animals in control group were fed with standard la-boratory diet.Tail flick latency to thermal stimulation was measured weekly.At the end of 10 weeks after administration of STZ,diabetic rats (and rats in control group)were further divided into myo-cardial ischemia-reperfusion group (group IR)and sham operation group (group Sham).The left an-terior descending branch of coronary artery was occluded for 30 min followed by reperfusion for 120 min,establishing myocardial ischemia-reperfusion.The histological immunofluorescence assay and Enzyme-linked immunosorbent assay (ELISA)were carried out to evaluate the changes of the expres-sions of CGRP and SP in the dorsal root ganglia.Results The tail flick latency was significantly in-creased in group DM,compared to the group C (P < 0.01).The immunoreactive materials for CGRP and SP in the sensory neurons in dorsal root ganglia of upper thoracic segments (T1-5 )were markedly declined in group DM (P <0.01 or P < 0.05).Furthermore,levels of SP and CGRP were signifi-cantly lower in the DRG of the group IR after myocardial ischemia-reperfusion,compared to that in the group sham (P <0.01).Conclusion Diabetes causes sensory denervation and obvious reduction of expression of SP and CGRP in the sensory neuron innervating heart during myocardial ischemia-reper-fusion,indicating impairment of adaptive reactivity of neuro-endocrine function of cardiac sensory nerves.

Objective To carry out the detection of JAGI gene in children with chronic cholestasis and to im-prove the diagnostic level and understanding of Alagille syndrome. Methods Two cases of chronic cholestasis with multiple organ involvement were selected as the research subjects and their clinical data,laboratory test results were col-lected. Two milliliter peripheral intravenous heparin anticoagulan blood was drawn from each patient. All fragments of 26 exons of the JAGI gene were amplified by polymerase chain reaction - sequence based on typing method. Results One patient with chronic cholestasis,heart murmur and dysmorphic face showed bile duct paucity in liver biopsy and a novel heterozygous mutation c. 809 809delG(p. G270Dfs*142)in 6 exon. Abnormal amino acid replaced JAG1 protein and resulted in truncation of the JAG1 protein. The part of epidermal growth factor(EGF)like repeats region loss and the cysteine rich region completely lost. One case with typical chronic cholestasis and dysmorphic face showed a known IVS20 - 2 5delTAAG heterozygous mutation which resulted in splice site changes. Conclusion A novel JAGI gene mutation c. 809 809delG(p. G270Dfs*142)is helpful to screen JAGI gene of Notch signal transduction pathway for chronic cholestasis with multiple organs involvement in children.
