BACKGROUND:The residual alveolar ridge in edentulous patients with osteoporosis always presents with a poor shape,which increases the difficulty in complete denture restoration.Until now,there are no predictors for residual alveolar ridge resorption or guidelines on the frequency of denture relines.OBJECTIVE:To investigate the correlation between the frequency of complete denture relines and serum bone turnover markers,osteocalcin (OC) and cross-linked carboxy-terminal telopeptide of type Ⅰ collagen (CTX),in elderly edentulous patients with osteoporosis,in order to provide reference for complete denture repair.METHODS:According to inclusion criteria,50 elderly edentulous patients with osteoporosis who had complete dentures were recruited in the study randomly.The frequency of complete denture relines was surveyed by related questionnaire and medical record,and the serum OC and CTX levels were detected by electrochemiluminescence immunoassay.Related data were analyzed statistically via Pearson correlation analysis.RESULTS AND CONCLUSION:It showed a strong positive correlation between the frequency of complete denture relines and the serum OC level (r=0.517,P ＜ 0.01).No significant correlation between relines frequency and the serum CTX level was observed (r=0.278,P=0.051 ＞ 0.05),but it showed a similar tendency between them.These findings indicate that to detect the levels of serum bone turnover markers may be conducive to evaluating curative effect of complete dentures in elderly edentulous patients with osteoporosis as well as to making subsequent diagnostic and therapeutic strategies.

Objective To investigate the expression of Gli1 protein in colorectal cancer (CRC) tissues,and evaluate its association with the prognoses of the patients.Methods A total of 106 patients were enrolled and their clinicopathological characteristics were analyzed.The expression of Gli1 proteins were detected by immunohistochemical staining,and its association with time to recurrence/metastasis (TTR) and overall survival (OS) of the patients were analyzed.Results The positive rate and expression intensity of Gli1 protein in recurrent or metastatic tumor tissues were higher than those in non-recurrent and non-metastatic tumor tissues [86.84 ％ (33/38) vs.58.82 ％ (40/68),1.32 scores vs.0.71 scores,both P ＜ 0.01),while the positive rate and expression intensity of Ki-67 protein remained no difference between both groups [97.37 ％ (37/38) vs.91.18 ％ (62/68),1.89 scores vs.1.75 scores,both P ＞ 0.05).The positive rates and expression intensities of Gli1 and Ki-67 proteins in CRC tissues were higher than those in adjacent tissues [26.42 ％ (28/106) and 0.27 scores;4.72 ％(5/106),0.05 scores] and normal tissues [3.33 ％ (1/106),0.03 scores;0,0.00 scores] (all P ＜ 0.01).Results of univariate analysis showed that the expression of Gli1 protein,tumor grade and lymph node involvement were significantly associated with TTR,but all of the clinicopathological factors had no obvious association with OS.The association remained significant between the expression of Gli1 protein and TTR in multivariate analysis (P ＜ 0.01).Conclusion The expression of Gli1 protein is an independent prognostic marker of recurrence or metastasis in CRC patients,its high expression implicates a high risk of CRC recurrence or metastasis.

Objective To observe the incidence of severe acute pancreatitis (SAP) in obese acute pancreatitis (AP) patients with medical treatment, and evaluate the impact of obesity in AP progression.Methods A multicenter prospective controlled study was conducted. APACHE Ⅱ scoring system was used to evaluate the severity of AP. Results 161 patients with mild AP(MAP) were enrolled, according to the cut-off point of 25 kg/m2, these patient were divided into obese group (79 patients) and non-obese group (82patients). The levels of CRP, hypertriacylglycerolemia, complication rate, incidence of SAP and mortality were observed under the circumstance of identical medical treatment. The levels of CRP in obese group and non-obese group were (117±109 ) mg/L and (35±36 ) mg/L(P<0.01). The number of obese patients with hypertriacylglycerolemia was two times as many as that in non-obese patients, but there was no significantly difference. There was no local complication in both groups, but the incidence of systematic complication in obese patients (20.3%) was significantly higher than that in non-obese group (6.1%, P<0.01). 16patients (20.3%) in obese group progressed into SAP, which was significantly higher than that in non-obese group (5 patients, 6.1%, P<0.01). One patient(1.3%) died in obese group, but no one died in non-obese group. In MAP patients with APACHE Ⅱ 4～7 points, the incidence of SAP (43.3%) in obese group was significantly higher than that in non-obese group (18.5%, P<0.05). Conclusions Obese MAP patients with APACHE Ⅱ 4～7 points were prone to develop into SAP. More aggressive interventions are needed.

Objective To evaluate the risk factors and prognosis of high risk bladder recurrence developing after radical nephroureterectomy(RNU) for upper tract urothelial carcinoma (UTUC).Methods The data of 148 UTUC patients who developed bladder tumor after RNU between January 2000 and December 2013 was retrospectively studied.There were 69 males and 79 females,aged from 34 to 82 years old (average 68 years old).83 patients were accompanied with hydronephrosis.80 patients were renal pelvic carcinoma.32 patients had the history of smoking.24 patients had the history of ureteroscope.68 patients had the tumor larger than 3 cm.Logistic regression model was used to analyze the risk factors of muscle invasive and high grade bladder recurrence lesions.We compared the clinocopathologic characteristics between primary UTUC and bladder cancer recurrence by using Fisher' s exact test.Cancer specific survival was analyzed using the Kaplan-Meier method,with the log-rank test used to assess significance.A Cox proportional hazard model was used for multivariate analysis.Results Of the 148 patients,non-muscle invasive (Tis、Ta and T1) tumors of primary UTUC and bladder recurrence were 51 (34.5％) and 119 (80.4％),respectively.High grade (G3) tumors of primary UTUC and bladder recurrence were 41 (27.7％) and 53(35.8％),respectively.During follow-up,94 (63.5％) experienced bladder recurrence once and 54 (36.5％) experienced multiple bladder recurrence.The median follow-up time was 59.5 (rang 8-142) months,48 (32.4％) patients died of UTUC.The grade of bladder cancer recurrence correlated with the grade (P =0.046),muscle-invasion (P =0.002) and tumor architecture (P =0.034) of the primary UTUC;muscle-invasive bladder cancer recurrence associated with that of the primary UTUC (P =0.009);bladder multiple recurrence related to gender (P =0.007).On multivariate logistic regression analysis,the muscle-invasion of primary UTUC was an independent risk factor for muscle-invasive (HR =5.512,95％ CI 1.654-18.37,P =0.004) and high grade (HR =3.948,95％ CI 1.589-9.813,P =0.004) bladder recurrence tumor.The muscle invasion of primary UTUC (HR =3.498,95％ CI 1.569-7.803,P =0.002) was a prognostic factor for cancer specific survival on multivariate Cox regression analysis.Conclusions Muscle-invasive UTUC tend to predict high risk bladder recurrence tumor,and the female could be more likely to appear multiple recurrence tumor.The muscle invasion of primary UTUC could be an independent prognostic factor for cancer specific survival.

Objective: To discuss the prevalence and influential factors of stroke among population in Jiangxi Province. Methods: Four cities in urban areas and four counties in rural areas were selected firstly, in which two districts or townships were selected; and then three communities or villages were chosen from each district and township, respectively, using the simple random sampling (SRS) method. Finally 15 269 subjects aging 15 years old or above, living in Jiangxi Province ≥6 months were randomly selected to participate in this survey from November 2013 to August 2014. Information of population characteristics, life behavior way, individual disease history were collected through questionnaire survey, and height, weight, waist circumference, blood pressure, body fat rate, visceral fat index and so on were measured by instruments. Risk factors of stroke prevalence were analyzed by the unconditioned logistic regression analysis. Results: A total of 15 269 participants (6 267 males) from 15 364 eligible participants were included in the statistical analysis. Out of which, 7 793 participants came from urban areas, and their average age was (53.04±17.91) years old. In this study, 226 stroke patients (117 males) were found among15 269 participants, including 122 urban participants and 104 rural participants, whose average age was (67.76±9.74) years old. The prevalence of stroke was 1 480.12/100 000 in 2014, which was separately 1 866.92/100 000 and 1 210.84/100 000 among males and females. The prevalence of people aging (45-49) years old was 413.79/100 000 (6/1 450) , while which among people aging 75 years old and above was 3 311.62/100 000 (61/1 842) . The prevalence of stroke among residents in Jiangxi presented an uprising tendency with age increasing (linear-by-linear association χ²=62.23, P<0.01). The research showed that when other influencing factors including gender, BMI, waist circumference, pulse-pressure difference, VAI, and sleeping time in non-working days were controlled, hypertensive patients had a higher risk of stroke than people without hypertension (OR=6.88, 95%CI: 4.90-9.67), drinkers had a higher risk of stroke than non-drinkers (OR=1.56, 95%CI: 1.17-2.08), compared with people <65 years old, people aged 65-74 years old and ≥75 years old had a higher risk of stroke, the value of OR (95%CI) were 1.88 (1.36-2.59) and 1.97 (1.39-2.80), respectively, compared with people with normal body fat percentage, people whose body fat percentage on high side and people who with high body fat percentage had a higher risk of stroke, the value of OR (95%CI) were 1.71 (1.18-2.48) and 1.74 (1.18-2.56), respectively, people with sleep time >8 h had a higher risk of stroke than those with sleep time of 6-8 h. Conclusion There was a high stroke prevalence among residents in Jiangxi province. Hypertension, drinking, age, BFP and sleep duration were associated with stroke prevalence. Corresponding measures for high-risk population and risk factors should be strengthened to prevent and control the stroke.

Objective To investigate effects of human postures on flow characteristics of iliac vein compression syndrome. Methods The numerical model of iliac vein was reconstructed from CT images of a typical patient with pelvic-type iliac vein compression syndrome with collateral veins. Based on the computational fluid dynamics method, the non-Newtonian model and the porous media model were adopted to describe effects of abnormal structures on blood flow and acquire the wall shear stress and pressure of iliac vein. The discrete phase model was used to study the residence conditions of erythrocytes under three human postures. Results The pressure gradient at two ends of the compressive region was lowest under lying state, while the iliac vein showed a high pressure under sitting and walking states. The local maximum wall shear stresses under three postures were found at narrow segment of the collateral vein and convergence region of two flows of right iliac vein. The maximum shear stress was largest under lying state and smallest under sitting state. The blood residence time of 52.2 s in the left iliac vein was the longest under sitting state. The residence time of 14.8 s was shortest under lying state. The blood residence time was 23.8 s under walking state. Conclusions Porous media model used to simulate the effect of abnormal structures was highly consistent with the angiography data. The venous hypertension under sitting and walking states was consistent with the clinical results, and the lying state could relieve the hypertensive condition. In terms of wall shear stress and blood residence time in iliac vein, the continual change between three human postures would cause endothelial damage and blood flow stasis alternately, thus increase the risk of thrombosis.
