Objective To assess the association between the depth of trophoblastic penetration into the tubal wall with serum concentrations of vascular endothelial growth factor (VEGF) and β-human chorionic gonadotropin (β-HCG). Meth-ods Eighty patients with a diagnosis of tubal pregnancy in the ampullary region underwent radical surgical treatment (sal-pingectomy), were included in this study. The serum levels of VEGF andβ-HCG were detected on the day of surgery. The se-rum level of VEGF was measured by ELISA. The serum level ofβ-HCG was quantified with a two-site immunofluorimetric assay based on the direct sandwichtechnique. Histological material was stained with Masson's trichrome to identify muscular fibers. Immunohistochemical staining was used for human placental lactogen (hPL) to identify intermediate trophoblast and determine the depth of trophoblastic invasion into the tubal wall. The ampullary pregnancies were classified histologically ac-cording to the depth of trophoblastic infiltration into the tubal wall. Results The mean serum values of VEGF andβ-HCG were significantly lower in patients with stage I tubal infiltration than those of stageⅡ, and which were significantly lower in patients with stageⅡthan those in stageⅢ(P<0.05). The threshold serum value of VEGF was 308.6 ng/L, the sensitivity was 100.0%and the specificity was 92.6%for stageⅠand stageⅡ. The threshold serum value of VEGF was 431.9 ng/L, the sensitivity was 79.3%and specificity was 79.2%for stageⅡandⅢ. The threshold serum value ofβ-hCG was 2 509.6 IU/L, the sensitivity was 91.7%and specificity was 81.5%for stageⅠand stageⅡ, and levels of 13 142.6 IU/L, 72.4%and 95.8%for stageⅡand stageⅢ. Conclusion The depth of trophoblastic penetration into the tubal wall is associated with maternal serum concentrations of VEGF andβ-HCG, which can be used as the evaluation index for histological staging of trophoblas-tic tissue infiltration.

Objective To investigate the significance of the mutation of c-kit gene in the development,(clinical) pathology and prognosis of gastrointestinal stromal tumors(GISTs).Methods The technique of(PCR-SSCP) was used to detect ckit gene mutation in 106 cases of GIST,and 57 of the cases were(followed-up).Results The c-kit gene mutation rate in the whole group was 45.3%(48/106),and(3.4)%(2/41) in benign GIST,and 70.8%(46/65) in malignant GIST.The 1-,3 and 5-year survival rates and median survival time of the mutation positive group were all markedlly lower than those of the(mutation) negative group.A comparison of the parameters that can differentiate the benign GISTs from malignant ones such as size,histological necrosis,aggressive grade,nucleus mitotic count and nuclear discrepancy,showed significant difference between the of postive and negative gene mutation(P

Theinnate immunity system of human body has more and more attention for its antibacterial, antiviral, maintainingimmunehemostasis and promoting tissue damage and repair and other physiological functions.As members of NOD-like receptors(NLRs), NOD1 and NOD2 receptors are identified as intracellular pattern recognition receptors(PRRs), can be identified with molecular damage endogenous(damage-associated molecular patterns, DAMPs)and exogenous injury-molecular pathogen associated molecular(pathogen-associated molecular patterns, PAMPs), and initiation of innate and specific immune response, maintain the steady balance of body.Recently, a bunch of evidence have demonstrated that the importance of NOD1 receptor and NOD2 receptor is not limited in field of anti-infection, and the insulin resistance, kidney and liver damage recovery, cardiovascular disease and tumorigenesis are also closely related with these two receptors.So the aim of this article is to interpret the NOD1 and NOD2 general structure and function, and summarize the link between these two PRRs and tumorigenesis and finally make a clue for cancer immunotherapy.

Serum Cardiac troponin Ⅰ (cTn Ⅰ) and lactic acid were measured in 128 neonatal patients with hypoxic-ischemic encephalopathy and 38 healthy neonates (control group). Serum cTn Ⅰ and lactic acid levels were higher in neonates with hypoxic-ischemic encephalopathy than those in healthy neonates (P < 0. 05 ); and the differences of these values were also statistically significant between the serious patients and the mild patients (P<0.05). Serum cTn Ⅰ and lactic acid are two sensitive markers for degree of myocardial injury and hypoxia in neonatal patients with hypoxic-ischemic encephalopathy.

Objective To compare the incidence of secondary surgical procedures after cervical disc arthroplasty vs anterior cervical discectomy with fusion in patients treated for symptomatic single level cervical spondylosis.Methods An online search of Pubmed, Medline, Ovid, Embase, Cochrane Library, CBM database, Wanfang data and VIP database were searched for prospective randomized controlled trial of cervical disc arthroplasty versus anterior cervical discectomy with fusion in incidence of secondary surgical procedures.Data were collected and extracted by two reviewers independently.Risk of bias was assessed using the criteria of Cochrane Reviews Handbook 5.1.0.Review Manager 5.2 software system was used to evaluate the data for Meta analysis.Results A total of 12 trials were included.Six of them were short-term follow up (two years).The 6 other trials were mid-and long-term follow up (mean 5.8 years).There are 4 trials with low risk of bias, 7 trials with moderate risk of bias, and 1 trial with high risk of bias.The results of meta-analysis showed there was no statistical difference in reoperation rate of adjacent level between the two groups at two years follow-up;however, the reoperation rate of non-fusion group was significantly lower in the non-fusion group compared with fusion group at mid-and long-term follow-up.The incidence of secondary surgical procedures at index level was higher in fusion group than in non-fusion group.No statistical difference was found between the two groups in using ‘ removal’ for secondary surgical procedure at two years follow-up;however, the rate of non-fusion group was significantly lower than fusion group at mid-and long-term follow-up.Conclusion Cervical disc arthroplasty was partly superior to anterior cervical discectomy with fusion in avoiding secondary surgical procedures of adjacent levels.However, non-fusion surgery doesn't have any advantages in short time (two years) follow up.Reducing the incidence of pseudarthrosis was an effective way to decrease the incidence of secondary surgery procedures in index level.

Objective To explore the current situation of basic psychological needs satisfaction (BPNS) and the relationship between index of well-being and BPNS among young workers in China.Methods The samples consisting of 5972 young workers were selected by stratified and random sampling according to the proportion.The Chinese vision of the Basic Needs Satisfaction in General Scale and the Index of Well-being Scale were used.Results The overall situation of BPNS of young workers (4.36 ± 0.71) was good,satisfied state of relatedness need (SSRN,4.70 ± 1.05) was the highest,satisfied state of autonomy need (SSAN,3.96 ± 1.21) and blocked state of autonomy need (BSAN,4.08 ± 1.17) were lower,blocked state of relatedness need (BSRN,3.20 ± 1.26) was the lowest; education and income had interaction on SSRN (F0.05(6.5948) =4.068,P ＜ 0.01)while there was no difference between gender on all of the dimensions.Pearson correlation analysis showed that all the dimensions of BPNS were significantly related to the index of well-being;and linear regression analysis showed that SSAN,SSRN and BSAN could forecast the index of well-being (adjR2 =0.339),β =0.457,0.186,-0.102 respectively.Conclusion The overall situation of BPNS of young workers is good ; and adjustment of SSAN,SSRN and BSAN could improve the index of well-being of young workers.

Objective To evaluate the relationships of the expression of orexin A in hypothalamus with hyperleptinemia, hyperinsulinism, and hyperlipidemia in alimentary obesity rats.Methods The alimentary obesity rat model was induced by high-fat diet in Wistar rats. The levels of leptin, insulin, C-peptide, total cholesterol (TC) and triglyeride (TG) were detected by luminescent immunoassay and biochemistry enzymic method. The gene expression of orexin A in rat hypothalamus was detected by real-time PCR. The correlation between orexin A and leptin was analyzed. Results After 8 weeks of high-fat diet feeding, the body weight, Lee's index, blood glucose, TG and TC significantly increased in obesity rat group (P＜0. 01). The levels of serum leptin, insulin and C-peptide were significantly higher in obesity rats than in controls [( 1.74±0. 36)μg/Lvs. (1.27±0.11) μg/L, (35±5) MIU/L vs. (23±4) MIU/L, (0.21±0.04) μg/L vs.(0. 14±0. 03) μg/L respectively, P＜0.01]. However, the level of orexin A mRNA was lower in obesity rats than in controls (6.8±2.3 vs. 14.5±3.6, t=-8.06, P＜0.01). The correlation coefficient (r) of orexin A mRNA with serum leptin, insulin, and C-peptide in alimentary obesity rat were -0. 726 (P＜0.01), -0. 506 (P＜0.01) and -0. 664 (P＜0.01), respectively. Conclusions High-fat diet can induce leptin-resistance and alimentary obesity in Wistar rat. The down-regulation of orexin A in rat hypothalamus would be correlated closely to the leptin and insulin resistance in alimentary obesity.

Objective To develop and test the reliability and validity of the dual-systems of self-control scale for children (DSSCSC).Methods The scale was developed based on previous studies and the theoretical framework of the dual system.Totally 1493 families from 5 provinces were recruited.Participants were asked to complete the DSSCSC.Item analysis was conducted to identify valid items.Then the construct validity of the scale was tested through exploratory and confirmatory factor analysis(EFA & CFA).Finally the reliability and criterion validity of the scale was examined.Results The scale was consisted of 23 items with 5 factors-planning,impulsivity,distractibility,persistence,and poor delay of gratification.They explained 50.46％ of the total variance.Besides,the CFA resuhs demonstrated a satisfactory construct validity of the scale (RMSEA =0.044,NFI =0.95,NNFI=0.97,CFI=0.97).The scores of DSSCSC and its subscales were significantly correlated with the TSCRS scores.The Cronbach' s α coefficients of the total scale was 0.855,and 5 subscales were 0.813,0.803,0.582,0.608,and 0.620 respectively.Conclusion The DSSCSC with 5 factors has a good reliability and validity,demonstrating it a valid tool to measure the children' s self-control in China.

Objective The purpose of this study was to evaluate the outcome of autogenous bone grafts in unilateral cleft lip and palate patients following early orthodontic tooth movement,and to determine the volume of new bone formation in the bone grafted region with spiral computed tomography.Methods Computed tomography scans of 12 patients were taken immediately preoperatively and at 6 months postoperatively.The patients underwent bone grafting between 9 and 13 years of age were divided into two groups based on whether postoperative orthodontic tooth movement were initiated or not.Three-dimensional models were created in each period,and the defect of alveolar cleft and volume of the newly formed bone were calculated in each patient.The roots of the moved teeth and their positions to the alveolar bone were also observed.Results The preoperative cleft width and cleft volume were not significantly different between both groups.The volume of the newly formed bone in group A was (0.98±0.23) mm3,significantly higher than that in group B,which was (0.73± 0.15) mm3.The rate of newly formed bone in group A was (72.5 ± 11.9)％,significantly higher than that in group B,which was (53.2±9.7)％.The cleft adjacent teeth could move smoothly into the bone grated area,with no root resorption observed in the computed tomography scans.Conclusions Early orthodontic tooth movement can reduce bone resorption in autogenous bone grafted unilateral cleft lip and palate patients through the observation of spiral computed tomography.It plays an active role in the bone remolding process after bone grafting.
