Objective To observe the clinical effect of psychological intervention combined with somatostatin in the operation of pancreas. Methods From January 2016 to August 2017, 68 cases of pancreatic surgery were treated in our hospital. The patients were randomly divided into the observation group (n=34) and the control group (n=34). All patients were treated with somatostatin after the operation of pancreas. The patients in the observation group were treated with positive psychological intervention, and the effect of the application was observed. Results After the intervention, the two groups of patients with SAS and SDS were improved, the improvement is more obvious in the observation group (P<0.05);the observation group anal exhaust time, patients with gastrointestinal peristalsis time, bed time, hospitalization time were significantly shorter than the control group (P<0.05). Conclusion The combination of psychological intervention and somatostatin can improve the psychological status and promote postoperative recovery of patients after pancreatic surgery.

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.

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.

Orthodontics is the procedure of managing the space .Space analysis is a comprehensive quantitative analysis that can analyze the factors that influence the arch space .It also helps to judge if the treatment goals can be reached , thus helping the treat-ment plan making and guiding clinical orthodontics .And space analysis related factors include crowding , curve of Spee, arch width, arch growth, arch protrusion, mesiodistal angulation, an so on.In this review, we summarizes the above-mentioned factors.

Objective To investigate the role of a cis-acting element,cell cycle genes homology region (CHR),in the transcriptional regulation of human NFBD1 gene (a nuclear factor with BRCT domain 1) by conducting a site-directed mutagenesis analysis on the element in human NFBD1 promoter region.Methods Wild type of NFBD1 promoter reporter,NFBD1-PS1-325,was used as template to make CHR mutant by using PCR based site-directed mutagenesis.Dual luciferase reporter assay was used to determine promoter reporter activity.Adiamycin treatment was employed to investigate the role of CHR in the transcriptional downregulation of NFBD1 after DNA damage.Results Site-directed mutagenesis of CHR caused a significant decrease in NFBD1 promoter activity,and also attenuated the transcriptional down-regulation of NFBD1 after DNA damage.Conclusion CHR element might be involved in both basic transcriptional regulation and transcriptional downregulation of NFBD1 after DNA damage.

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.
