Objective: To investigate the effect of curcumin (Cur) on cycle in HepG2 cells and the action of microtubule system for it. Methods: The proliferation inhibition of Cur on HepG2 cells was evaluated by MTT assay; The effect of Cur on the cycle of HepG2 cells was analyzed by flow cytometry; Confocal laser scanning microscopy (CLSM) was used to observe the changes of microtubule in HepG2 cells after treated with Cur; Western blotting was performed to determine the expression of α-tubulin; The in vitro effects of Cur on tubulin polymerization and depolymerization activities were studied. Results: Cur inhibited the proliferation of HepG2 cells in a dose- and time-dependent manner. With Cur concentration increasing, the proportion of HepG2 cells arrested in G2/M phase was also increased. CLSM showed that Cur could seriously destroy the cell microtubule structure and change the polymerization state of tubulin. Western blotting showed that the decrease of the expression level of α-tubulin was related to Cur concentration. Cur could also interfere the microtubule polymerization and depolymerization activities. Conclusion: Cur could inhibit the proliferation of HepG2 cells by destroying the microtubule structure and downregulating the expression of α-tubulin, and make HepG2 cells arrested in G2/M phase.

Objective To investigate the expression of phospho-histone H3 (PHH3) protein in pancreatic neuroendocrine neoplasms (PNENs) and explore its potential value for pathological grading of PNENs.Methods Clinical and pathological data of 283 patients with PNENs treated in Changhai Hospital from December 2000 to May 2016 were retrospectively analyzed.PNENs tissue chip was prepared,and immunohistochemistry was used to examine the expression of PHH3 and Ki67.The receiver operating characteristic curve for PHH3 was drawn and the area under the curve(AUC) was calculated to determine the cutoff value for PNENs grading.Ki67 was used for PNENs grading according to domestic and intemational criteria for PNENs classification.The relationship of PHH3 and Ki67 classification with clinical pathological features and prognosis of PNENs as well as the correlation between the two classification methods were analyzed.Results Of 283 patients,132 were male and 151 were female,aged from 16 to 78 years old.The average age was (50 ± 1) years old.There were 44 cases with functional PNENs and 239 with non-functional PNENs.The diameter of tumors ranged from 1.1 cm to 17 cm and the average diameter was (4.1 ± 1.2)cm.According to the Ki67 standard,there were 127,116,33 and 7 cases of Grade G1,G2,pancreatic neuroendocrine tumor(PNET) G3 and pancreatic neuroendocrine cancer(PNEC) G3.According to the PHH3 standard,there were 118,119,3 8 and 8 cases of Grade G1,G2,PNET G3 and PNEC G3.There was a positive correlation between the two grading criteria (r =0.941,P ＜0.001).PHH3 expression and PNENs grading were not correlated with age,gender,tumor functional or not and tumor locations (all P ＞ 0.05),but were both positively correlated with tumor size,histological grade,lymph node metastasis,TNM stage and prognosis (all P ＜0.05).The average time of observing PHH3 and Ki67 staining per case in the immunohistochemistry of tissue chip was 9 min and 45 min,respectively.Conclusions Detection of PHH3 expression in PNENs can be used for the pathological diagnosis,grading and prognostic evaluation,which was more accurate and convenient than Ki67 criteria.

A novel method based on the separation and enrichment effect of magnetic beads and the fully complementary hybridization of two DNA strands was developed for highly sensitive detection of bacterial DNA using a surface-enhanced Raman spectroscopy (SERS) with 5,5’-dithio-bis(2-nitrobenzoic acid) (DTNB)-modified gold nanoparticles as reporter probes. Capture probe was immobilized onto the surface of streptavidin-enwrapped magnetic beads ( SA-MB ) through high affinity between biotin and avidin, by which the target bacterial DNA sequences that connected with the reported probe decorated AuNPs with DTNB and SH-DNA ( AuNPs@DTNB@DNA) were captured and loaded onto the magnetic beads by the hybridization reaction with the capture probe. Compared with previous methods, this design shortened the distance between particles by the ways that the magnetic beads tempted to nanoparticles aggregation, and produced the plasma resonance coupling effect, which increased the SERS signal significantly. The results showed that, under the optimized conditions and in the concentration range from 5 pmol/L to 5 nmol/L, the method performed a good linear relationship between Raman intensity and DNA concentration. The limit of detection ( LOD) of bacterial DNA was estimated to be 5 pmol/L. The method is simple and low cost, and can be used in the sensitive and selective detection of bacterial DNA.

BACKGROUND:In treatment of lumbar diseases, lumbar fusion therapy fails in 20%of cases and may lead to a series of complications such as pain, intervertebral space col apse, and delayed kyphosis deformity.
OBJECTIVE:To observe the effect of nucleus pulposus on interbody fusion after removing the anterior column disc of rabbit lumbar vertebra.
METHODS:A total of 36 healthy Japanese white rabbits were randomly and equal y divided into three groups, with 12 rabbits in each group. (1) Group of anterior longitudinal ligament+bone grafting:The L3 intercalated disc were wel exposed and anterior longitudinal ligament was stripped, obtaining a space to L3 intercalated disc, then the iliac bone was implanted. (2) Group of excising anterior 1/3 disc+bone grafting:After the anterior 1/3 disc tissue was excised, the iliac bone was implanted and sutured as Group of anterior longitudinal ligament+bone grafting. (3) Group of excising anterior 1/3 disc+fixation:After the anterior 1/3 disc tissue was excised, the iliac bone was implanted and the anterior column fixation was performed.
RESULTS AND CONCLUSION:Biomechanical testing showed that, at 12 weeks, the verticality tensile force in the group of anterior longitudinal ligament+bone grafting was obviously higher than other two groups, and have better fusion rate and could bear stronger force. Lateral position lumbar radiography showed that, the bone graft was absorbed and no new bone grew into the intervertebral space in the group of excising anterior 1/3 disc+bone grafting at 12 weeks;the formation of osseous bridge was found in the group of excising anterior 1/3 disc+fixation;complete bony fusion was found in the group of anterior longitudinal ligament+bone grafting. Histological examinations showed that, at 12 weeks, no bone tissue formed in the group of excising anterior 1/3 disc+bone grafting;a smal amount of bone trabecula and osteocytes were observed in the group of excising anterior 1/3 disc+fixation;a great quantity of newborn bone trabecula and osteocytes, remodeling lamel ar bone and canalis haversi structure were observed in the group of anterior longitudinal ligament+bone grafting. The stability of anterior column has notable effect on interbody fusion, after the anterior column disc is destroyed, the free nucleus pulposus may affect spinal fusion, so restoring the stability of the anterior column may promote interbody fusion, but stil cannot get solid spinal fusion.

Objective To explore the value of urinary N-terminal telopeptide of type Ⅰ collagen (uNTX) combined with bone scintigraphy (BS) for the diagnosis of bone metastases.Methods A total of 227 patients suspected of bone metastases by BS were selected from Jan to May of 2012.UNTX was tested for each subject.The threshold of uNTX was chosen as 65 nmol bone collagen equivalents (BCE)/mmol creatinine (Cr) for the diagnosis of bone metastasis.Patients with uNTX greater than 65 nmol BCE/mmol Cr would be diagnosed as having bone metastasis.Other examinations (CT,MRI,PET/CT or bone biopsy) were also performed to confirm the diagnosis.The uNTX values of benign and malignant bone lesions were compared using two-sample t test.The diagnostic efficacy of uNTX combined with BS was evaluated.A ROC curve was analyzed to evaluate the cut-off value of uNTX for the diagnosis of bone metastasis.Results The mean value of uNTX of all 227 patients was (84.30± 13.29) nmol BCE/mmol Cr,which was significantly higher than the upper limit of normal range (t =21.875,P＜0.01).Using 65 nmol BCE/mmol Cr as the threshold,197 cases were diagnosed as with and 30 without bone metastases,in which 188 and 27 were respectively confirmed by other examinations.The mean uNTX was (88.73 ± 8.37) and (60.76± 9.14) nmol BCE/mmol Cr in patients with and without bone metastases,respectively (t =-18.134,P＜0.01).The sensitivity,specificity,positive predictive value,negative predictive value,accuracy and Youden index of uNTX combined with BS were 98.4％ (188/191),75.0％ (27/36),95.4％ (188/197),90.0％ (27/30),94.7％ (215/227) and 73.4％ respectively.The cut-off value by ROC curve analysis was 78.88 nmol BCE/mmol Cr and the area under the curve was 0.982.Using 78.88 nmol BCE/mmol Cr as threshold,the corresponding sensitivity,specificity,positive predictive value,negative predictive value,accuracy and Youden index were 97.4％(186/191),94.4％(34/36),98.9％(186/188),87.2％(34/39),96.9％(22/227) and 91.8％ respectively.Conclusions Using the cut-off value of 78.88 nmol BCE/mmol Cr,uNTX may have clinical value in helping the differential diagnosis of bone scintigraphy for patients suspected of metastatic bone disease.
