ABSTRACT
[Abstract] Objective To explore the body index and typing characteristics of Xibe nationality. Methods According to Anthropomatric Methods, height, chest circumference, sitting height, shoulder width, pelvic width and body mass morphological indexes were collected from 588 Xibe people in Yili area and 420 Xibe people over 18 years old in Shenyang area. After data collation, body index and typing were calculated and analyzed statistically. Results Except for Xibe male stature-shoulder breadth index and Caup’ s index in Yili area and female stature-shoulder breadth index in Shenyang area, there were differences among age groups in other indexes (P < 0. 05). Except for male stature-chest circumference index, stature-crista iliaca index, female stature-chest circumference index, stature-sitting height index, Manouvrier’s skelic index, there were differences among regions (P<0. 05). The adult body shape of Xibe nationality was mainly of wide chest, wide shoulder, long trunk, wide pelvis, medium leg and sub-long leg (male), sub-short leg and medium leg (female), and overweight. Conclusion There are regional and age differences in the body index and typing of Xibe adults. Compared with other ethnic minorities, Xibe nationality’s stature-chest circumference index, stature-shoulder breadth index, stature-crista iliaca index, Caup’s index are at a higher level. The proportion of legs and body of Xibe nationality is in the middle level, while the proportion of trunk is slightly shorter for men and slightly longer for women.
ABSTRACT
AIM:To investigate the effect of retinoic acid receptor gamma(RARG)on the viability and migra-tion ability of gastric cancer cells.METHODS:The expression of RARG in gastric cancer and normal gastric tissues and its correlation with the overall survival rate of gastric cancer patients were analyzed by bioinformatics.The expression of RARG was promoted and inhibited by over-expression plasmid transfection and RNA interference technique in gastric can-cer cells in vitro,respectively.MTT and Transwell assays were used to detect the effect of RARG on the viability and mi-gration ability of gastric cancer cells.The effect of RARG on regulating the Wnt/β-catenin signaling pathway was evaluated by Western blot and TOP/FOP dual-luciferase reporter assay.The protein interaction of RARG and β-catenin was deter-mined by co-immunoprecipitation and immunofluorescence co-localization assay.RESULTS:Over-expression of RARG en-hanced the viability and migration ability of gastric cancer SGC 7901 cells(P<0.05).Knockdown of RARG attenuated the viability and migration ability of gastric cancer MGC-803 cells(P<0.05).At the same time, RARG over-expression in-creased the protein expression levels of β-catenin, c-Myc, cyclin D1, Twist and Snail(P<0.05), and the activity of TOP/FOP dual-luciferase reporter gene(P<0.05).In addition, RARG interacted with β-catenin protein in the gastric cancer cells.CONCLUSION:RARG promotes the viability and migration ability of gastric cancer cells via activating the Wnt/β-catenin signaling pathway,thus playing an important role in the development of gastric cancer.
ABSTRACT
<p><b>OBJECTIVE</b>To identify the clinical characteristics and risk factors of frequent peritoneal dialysis (PD)-related peritonitis.</p><p><b>METHODS</b>A retrospective analysis was conducted in the peritonitis patients undergoing continuous ambulatory peritoneal dialysis (CAPD) in our hospital. Frequent PD-related peritonitis was defined by two or more onsets in one year, and the patients with only one onset served as the control group. The clinical and laboratory data of the two groups were compared and the risk factors of PD-related peritonitis analyzed.</p><p><b>RESULTS</b>Forty-four episodes of peritonitis were recorded in the 16 patients with frequent PD-related peritonitis, as compared to 53 episodes in the 45 control patients. Compared with those in the control group, the patients with frequent peritonitis had significantly higher blood pressure (P<or=0.05) but lower hemoglobulin (P<or=0.05) and plasma albumin (P<or=0.01), with higher rates of edema (P<or=0.01), gram-negative bacteria and fungal infection (P<or=0.05) and PD catheter removal (P<or=0.05). No significant differences were found between the two groups in age, mode of catheter placement surgery, intervals between PD initiation and peritonitis occurrence, inducing factors of peritonitis, incidence of dyspnea, serum creatinin, urea, calcium, mineral phosphorus, blood or dialysate leucocytes (P>0.05). Variables identified to be associated with an increased likelihood of frequent PD-related peritonitis included hemoglobulin<70 g/L (OR=0.135, P<or=0.01) and plasma albumin<30 g/L (OR=0.181, P<or=0.05).</p><p><b>CONCLUSION</b>Compared with the patients with only one annual occurrence of peritonitis, the patients with frequent PD-related peritonitis have severer malnutrition and water overload, which are probably correlated to the high rates of PD catheter removal and poor prognosis. Severe anemia and proteinemia are risk factors and also predictive factors of frequent PD-related peritonitis. Measures to ameliorate anemia and proteinemia and effective management of celiac endogenous infection may help prevent and control frequent PD-related peritonitis.</p>
