OBJECTIVETo investigate mRNA expression of syndecan-1 and heparanase in gastric carcinoma, and their correlation with the growth-pattern, invasion, metastasis and prognosis of gastric carcinoma.

METHODSIn situ hybridization technique was used to examine mRNA expression of syndecan-1 and heparanase in 118 specimens of gastric carcinoma.

RESULTSThe positive rates of syndecan-1 mRNA and heparanase mRNA were 42.4% and 55.9%, respectively. The expression of syndecan-1 mRNA and heparanase mRNA were related to tumor invasion depth (chi(2) = 32.95, P = 0.001; chi(2) = 23.19, P = 0.001), vessel invasion (chi(2) = 46.22, P = 0.001; chi(2) = 33.78, P = 0.001), lymph node (chi(2) = 28.62, P = 0.001; chi(2) = 25.43, P = 0.001) and distant metastasis (chi(2) = 63.30, P = 0.001; chi(2) = 65.76, P = 0.001), and syndecan-1 mRNA positive expression was related to tumor size (chi(2) = 6.25, P = 0.012). There was a negative relationship between Syndecan-1 mRNA and heparanase mRNA expression (r = -0.844, P = 0.001). The mean survival time of cases with low expression of syndecan-1 mRNA was significantly shorter than that of cases with high expression (r = 36.48, P = 0.001), and meanwhile, the mean survival time of heparanase mRNA positive cases was significantly shorter than that of cases with negative expression (r = 34.41, P = 0.001).

CONCLUSIONSThe mRNA expression of syndecan-1 and heparanase can predict the invasion and metastasis of gastric carcinoma, and can be used as markers of prognosis of gastric carcinoma.

OBJECTIVETo investigate relationship between expressions of hypoxia inducible factor-1alpha (HIF-1alpha) and insulin-like growth factor-II (IGF-II) as well as their correlation with angiogenesis and prognosis in gastric carcinoma.

METHODSHIF-1alpha and IGF-II mRNA expression were analyzed using in situ hybridization, microvessel density (MVD) was determined by anti-CD34 immunostaining in 118 cases gastric carcinoma.

RESULTSThe positive rates of HIF-1alpha mRNA and IGF-II mRNA were 49.2% and 47.4%, respectively. In stage T3-T4 cases, positive rates of HIF-1alpha and IGF-II mRNA expression, the frequencies of vessel invasion, lymph node and distant metastasis were significantly higher than those in stage T1-T2 cases. The mean MVD in stage T3-T4 tumors, vessel invasion, lymph node metastasis and distant metastasis were significantly more frequent than those in stage T1-T2 tumors. The mean MVD in tumors with positive HIF-1alpha and IGF-II mRNA expression was significantly higher than those in tumors without HIF-1alpha and IGF-II mRNA expression. The expression of HIF-1alpha was positively correlated with IGF-II mRNA. There were positive correlations between MVD and expression of HIF-1alpha and IGF-II mRNA, respectively. The mean survival time and 5-year survival rate in cases with positive HIF-1alpha and VEGF expression and MVD value >/= 41.5 were significantly shorter than those in cases with negative HIF-1alpha and VEGF expression and MVD value < 41.5.

CONCLUSIONSHIF-1alpha and IGF-II play an important role in tumor invasion and metastasis, especially in tumor angiogenesis. So test of the expression of HIF-1alpha and IGF-II may act as a useful index of treatment and prognosis.

OBJECTIVETo explore selection and efficacy assessment for membranous urethral trauma caused by pelvic fracture.

METHODSFrom June 2000 to August 2010, 72 patients with membranous urethral trauma caused by pelvic fracture were selected. There were 46 males and 26 females,ranging age from 26 to 62 years (averaged 35.2 years). The time from injury to hospitalization time was 1 to 3 hours. According to Tile pelvic fracture classification, there were 8 patients with type A, 45 patients with type B, 19 patients with type C. Thirty of the 35 patients with partial rupture of posterior urethral were treated by catheterization,5 patients treated by rupture anastomosis on the stage I combined with cystostomy; 25 of the 37 patients with complete rupture of posterior urethra were treated by early realignment, and 12 patients were treated by cystostomy. Urinary incontinence, impotence and urethrostenosis were evaluated.

RESULTSAll patients were followed up for 5 to 10 years (mean 7.7 years). Incidence of urethrostenosis, impotence and urinary incontinence in patients treated by cystostomy were significantly higher than rupture anastomosis on the stage I and early realignment (P < 0.05); while incidence in patients treated by catheterization was significantly lower than other groups (P < 0.05).

CONCLUSIONFor patients with partial rupture of posterior urethral, catheterization and rupture anastomosis on the stage I are preferred methods; while patients with complete rupture of posterior urethra, early realignment is a preferred method with advantages of simple operation and less complications.

OBJECTIVETo observe the changes of nitric oxide (NO) and endothelin (ET) serum level in the Guangxi BA-MA minipigs whose carotid arteries were injured by balloon denudation and in the patients with carotid stent assisted angioplasty.

METHODSTwelve Guangxi BA-MA minipigs were chosen. High fat/cholesterol feeding and endovascular balloon denudation were used to create a carotid artery atherosclerotic stenosis animal model. Blood samples were collected from peripheral veins before starting the procedure, and again, at 2 and 3 weeks after the procedure, respectively. Serum NO and ET concentrations of blood samples were tested. Nineteen patients with carotid artery stenosis who underwent stent assisted angioplasty were randomly selected, and their serum NO and ET were tested using the same methods as above.

RESULTSIn the animal group, there was a significant decrease of mean NO concentration at 2 weeks after carotid injury (t-test, P < 0.05), however, no significant change of ET was observed. A very significant increase of ET was observed at 3 weeks after the procedure (t-test, P < 0.01). In the patient group, there were no significant differences among serum NO or ET concentration of peripheral vein blood before, immediately after, and 6 h after the endovascular treatment.

CONCLUSIONSIn this study, a decrease of NO concentration and an increase of ET concentration of peripheral vein blood are found in BA-MA minipigs after carotid arteries are injured by balloon denudation, which might be a cue for the formation of atherosclerosis. However, no significant changes are observed in this group of patients who underwent carotid angioplasty treatment. Therefore, further studies are needed.

OBJECTIVETo assess the effect of the different treatments targeted at different types of radial head fracture and radial neck fracture.

METHODSA retrospective study was performed in 87 patients from February 2006 to March 2007. Fifty-four patients with radial head fractures included 36 males and 18 females, aged from 18 to 65 years (the average age was 33); Forty of them resulted from crashing, 8 from traffic injury and 6 from falling injury. According to Mason classification system, there were 15 type I, 23 type II and 16 type III. Thirty-three patients with radial neck fractures included 21 males and 12 females, aged from 9 to 17 years (the average age was 13), 29 of them resulted from crashing, 1 from traffic injury and 3 from falling injury. According to O'Brien classification system, there were 8 type I, 14 type II and 11 type III. Type I of radial head fractures and radial neck fractures were immobilization with cast, the patients with type II of radial head fractures were treated with open reduction and micro-screw or T-trapezoid and bridge-shaped plate fixation and type III had operations to fix with bridge-shaped locked plate and repair the broken annular ligament, or replace heads with prosthesis. All patients with type II and type III of radial neck fractures were treated with closed reduction by leverage and percutaneous intra-medullary nailing.

RESULTSThe patients were followed up for 4-12 months (mean 7.2 months). The functional recovery degrees were evaluated with Wheeler's evaluation system. In group of radial head fractures, the results were excellent in 26 patients, good in 20, fair in 6 and poor in 2, the excellent and good rate was 85.2%. In group of radial neck fractures, the results were excellent in 20 patients, good in 9, fair in 4 and poor in no patient, and the excellent and good rate was 87.9%.

CONCLUSIONSDifferent types of fractures should choose different surgical methods according to their characters. The excellent functional recovery depend on anatomical reduction, retaining the head of radius, early repairing and protecting the broken annular ligament of radius, and early functional training.

OBJECTIVETo investigate the relationship between apolipoprotein A5(apoA5) - 1131T > C polymorphism and the susceptibility of coronary artery disease (CAD) in Chinese.

METHODSThe restriction fragment length polymorphism of apoA5 gene - 1131T > C was studied using PCR in a case-control study which enrolled 235 patients with CAD diagnosed by angiography and 262 healthy controls from Jiangsu province.

RESULTSThe frequencies of T, C allele were 59.57%ì40.43% and 65.65%, 34.35% in CAD group and control group respectively. There was statistically significant difference in allele frequencies between CAD group and control group (P < 0.05). The susceptibility to CAD for the CC genotype was much higher than that for wild type TT (OR = 1.872, 95% CI = 1.039 - 3.376, P = 0.037), even after the use of Logistic regression models (OR = 2.285, 95% CI = 1.222 - 4.274, P = 0.012). In control group, there was significant difference in TG levels among different genotypes, the C allele carriers had higher serum TG concentration (P = 0.007).

CONCLUSIONapoA5 - 1131T > C polymorphism is associated with an increased risk of CAD and is also in strong association with serum TG levels.

Background: Transarterial chemoembolization (TACE) is recommended as the standard care for unresectable hepa-tocellular carcinoma (HCC) at Barcelona Clinic Liver Cancer (BCLC) stage A–B. However, the efficacy of TACE on large (≥ 10 cm) stage A–B HCC is far from satisfactory, and it is proposed that hepatic artery infusion chemotherapy (HAIC) might be a better first-line treatment of this disease. Hence, we compared the safety and efficacy of HAIC with the modified FOLFOX (mFOLFOX) regimen and those of TACE in patients with massive unresectable HCC. Methods: A prospective, non-randomized, phase Ⅱ study was conducted on patients with massive unresectable HCC. The protocol involved HAIC with the mFOLFOX regimen (oxaliplatin, 85 mg/m2intra-arterial infusion; leucovorin, 400 mg/m2intra-arterial infusion; and fluorouracil, 400 mg/m2bolus infusion and 2400 mg/m2continuous infusion) every 3 weeks and TACE with 50 mg of epirubicin, 50 mg of lobaplatin, 6 mg of mitomycin, and lipiodol and polyvinyl alcohol particles. The tumor responses, time-to-progression (TTP), and safety were assessed. Results: A total of 79 patients were recruited for this study: 38 in the HAIC group and 41 in the TACE group. The HAIC group exhibited higher partial response and disease control rates than did the TACE group (52.6% vs. 9.8%, P < 0.001;83.8% vs. 52.5%, P = 0.004). The median TTPs for the HAIC and TACE groups were 5.87 and 3.6 months (hazard radio [HR] = 2.35, 95% confidence interval [CI] = 1.16–4.76, P = 0.015). More patients in the HAIC group than in the TACE group underwent resection (10 vs. 3, P = 0.033). The proportions of grade 3–4 adverse events (AE) and serious adverse events (SAE) were lower in the HAIC group than in the TACE group (grade 3–4 AEs: 13 vs. 27, P = 0.007; SAEs: 6 vs. 15, P = 0.044). More patients in the TACE group than in the HAIC group had the study treatment terminated early due to intolerable treatment-related adverse events or the withdrawal of consent (10 vs. 2, P = 0.026). Conclusions: HAIC with mFOLFOX yielded significantly better treatment responses and less serious toxicity than did TACE. HAIC might represent a feasible and promising first-line treatment for patients with massive unresectable HCC.

Objective: To investigate factors associated with life satisfaction among adolescents who have been relocated for poverty alleviation,so as to provide scientific evidence to support adolescent physical and mental well being. Methods: A multi stage stratified random sampling was conducted from June to August 2023 across 24 relocation sites in 8 counties of 4 cities in Shanxi Province. A total of 631 adolescents aged 10-19 were surveyed regarding personal characteristics, family environment, health behaviors, mental health, and social capital. Univariate analysis of variance and binary Logistic regression were used to explore the influencing factors. Results: The life satisfaction rate of the relocated adolescents was 63.9%(403/631), and the average score of life satisfaction was (23.21±6.28). The Logistic regression analysis showed that, significant factors affecting life satisfaction of the relocated adolescents included age (17-19 years old: AOR= 0.54 , 95%CI =0.33-0.88), subjective family economic status (moderate: AOR=1.70, 95%CI =1.04-2.76; good: AOR=6.95, 95%CI =1.85-26.16), sleep quality (good: AOR=1.61, 95%CI =1.09-2.38), depression ( AOR=0.94, 95%CI =0.90-0.99), and social capital ( AOR=1.17, 95%CI =1.10-1.23)( P <0.05). Conclusions The satisfaction of 17-19 year old adolescents who have relocated for poverty alleviation is relatively low, while those with better family economic status, high sleep quality, low depression level and rich social capital showed high life satisfaction. Targeted interventions by families, communities, schools, and social institutions are recommended to improve adolescents quality of life.
