ObjectiveTo analyze the surgical treatment of visceral artery aneurysm (VAAs).MethodClinical data of 19 patients surgically treated for visceral artery aneurysm in our hospital from Feb 2002 to Jun 2010 were reviewed. There were 7 cases of splenic, 1 of right hepatic, 1 of left gastric,3 of pancreaticoduodenal,2 of gastroduodenal, 1 of superior mesenteric, 1 of middle colic, 1 of left colic and 2 of renal artery aneurysms. Rupture of the aneurysm occurred in 12 patients. Transcatheter arterial embolization was performed in 13 cases, other 6 cases received open surgical treatment.ResultsFour patients suffered from recurrent bleeding after first embolization, 2 of those received surgery to stop bleeding, another 2 were successfully managed by second embolization.Bleeding were rapidly controlled in 8 ruptured patients associated with shock. Duodenum incomplete obstruction developed in 1 patient after pancreaticoduodenal artery embolization, another 2 patients suffered from partial splenic infarction after splenic artery operation. 18 cases were followed-up from 2 to 103 months without aneurysm recurrence.ConclusionsEndovascular embolization and open surgery for VAAs are safe and effective, endovascular intervention and embolization is especially life saving for ruptured pseudo-aneurysm cases.

The objectives of this study were to (1) determine the distribution and synthesis of pericellular matrix (PCM) molecules (collagen Ⅵ, collagen Ⅳ and laminin) in rat temporomandibular joint (TMJ) and (2) investigate the effects of PCM molecules on chondrocytes against inflammation in osteoarthritis. Four zones (fibrous, proliferating, mature and hypertrophic) of condylar cartilage and three bands (anterior, intermediate and posterior) of disc were analysed by immunohistochemistry for the presence of PCM molecules in rat TMJs. Isolated chondrocytes were pre-treated with PCM molecules before being subjected to interleukin (IL)-1β treatment to stimulate inflammation. The responses of the chondrocytes were analysed using gene expression, nitric oxide release and matrix metalloproteinase (MMP)-13 production measures. Histomorphometric analyses revealed that the highest areal deposition of collagen Ⅵ (67.4%), collagen Ⅳ (45.7%) and laminin (52.4%) was in the proliferating zone of TMJ condylar cartilage. No significant difference in the distribution of PCM molecules was noted among the three bands of the TMJ disc. All three PCM molecules were expressed intracellularly by chondrocytes cultured in the monolayer. Among the PCM molecules, pre-treatment with collagen Ⅵ enhanced cellular proliferation, ameliorated IL-1β-induced MMP-3, MMP-9, MMP-13 and inducible nitric oxide synthase gene expression, and attenuated the downregulation of cartilage matrix genes, including collagen Ⅰ, aggrecan and cartilage oligomeric matrix protein (COMP). Concurrently, collagen Ⅵ pretreatment inhibited nitric oxide and MMP-13 production. Our study demonstrates for the first time the distribution and role of PCM molecules, particularly collagen Ⅵ, in the protection of chondrocytes against inflammation.

Background::The dermoscopic features of rosacea have already been reported. However, the current findings are incomplete, and little is known about phymatous rosacea. Hence, this study aimed to summarize and compare the dermoscopic features and patterns of three rosacea subtypes (erythematotelangiectatic [ETR], papulopustular [PPR], and phymatous [PHR]) in the Chinese Han population and to evaluate whether these features differ with patients’ genders, ages, and durations.Methods::Dermoscopic images of 87 rosacea patients were collected in non-polarized and polarized dermoscopy contact modes at 20-fold magnification. Dermoscopic features, including vessels, scales, follicular findings, and other structures, were summarized and evaluated.Results::The reticular linear vessels and red diffuse structureless areas of ETR were distinctive. For PPR, red diffuse structureless areas, reticular linear vessels, yellow scales, follicular plugs, and follicular pustules were typical dermoscopic criteria. The common dermoscopic features of PHR were: orange diffuse structureless areas, linear vessels with branches, perifollicular white color, orange focal structureless areas, and white lines. The following features statistically differed among the three rosacea subtypes: reticular linear vessels ( P < 0.001), unspecific linear vessels ( P= 0.005), linear vessels with branches ( P < 0.001), yellow scales ( P = 0.001), follicular plugs ( P < 0.001), perifollicular white color ( P < 0.001), red diffuse structureless areas ( P = 0.022), orange diffuse structureless areas ( P < 0.001), red focal structureless areas ( P = 0.002), orange focal structureless areas ( P = 0.003), white lines ( P < 0.001), follicular pustules ( P < 0.001), and black vellus hairs ( P < 0.001). Conclusions::The dermoscopic patterns of ETR are red diffuse structureless areas and reticular linear vessels. For PPR, the pattern comprehends combinations of red diffuse structureless areas, reticular linear vessels, yellow scales, follicular plugs, and follicular pustules. Meanwhile, PHR is characterized by remarkable orange diffuse structureless areas, linear vessels with branches, perifollicular white color, orange focal structureless areas, and white lines.

OBJECTIVETo study the risk factors for moderate and severe iron deficiency anemia (IDA) in infants aged 6-12 months, and to preliminarily investigate the effects of IDA on the neuromotor development and temperament characteristics of infants.
METHODSA total of 326 infants aged 6-12 months with IDA were classified into three groups: mild IDA (n=176), moderate IDA (n=111), and severe IDA (n=39) according to the severity of anemia. The risk factors for moderate or severe IDA were investigated by multivariate logistic regression analysis. Three hundred and forty-six infants without IDA who showed matched age, sex, and other backgrounds were selected as the control group. The Gesell Development Diagnosis Scale was used to evaluate children's mental development. The Temperament Scale for infants was used for evaluating children's temperament.
RESULTSThe univariate analysis showed that the severity of IDA was associated with sex, birth weight, gestational age, multiple birth, maternal anemia during pregnancy, and mother's lack of knowledge about IDA (P<0.05). Setting the mild IDA group as control, the multivariate logistic regression analysis showed that multiple birth, premature birth, low birth weight (<2500 g), maternal anemia during pregnancy, breast feeding, and mother's lack of knowledge about IDA were the risk factors for severe IDA (OR>1; P<0.05); premature birth, breast feeding, and mixed feeding were the risk factors for moderate IDA (OR>1; P<0.05). The IDA group had significantly lower scores in Gesell general development quotient, gross motor, adaptive behavior, and fine motor than the control group (P<0.05). The IDA group had higher percentages of children with difficulty and intermediate difficulty temperaments than the control group (P<0.05). The IDA group had significantly higher scores in activity level, rhythmicity, adaptability, and perseverance than the control group (P<0.05).
CONCLUSIONSThe severity of IDA is associated with premature birth, multiple birth, low birth weight, feeding pattern, maternal anemia during pregnancy and mother's lack of knowledge about IDA in infants aged 6-12 months. Infants with IDA have delayed neuromotor development and most of them have negative temperaments. More attention should be paid to mental and behavior problems for the infants. It is necessary to provide guidance for their parents in feeding and education.

The aim of this study was to investigate the apoptosis-inducing effect of cinnamic aldehyde (CA) on chronic myeloid leukemic (CML) cells and its mechanism. K562 cells and primary bone marrow mononuclear cells (MNC) from patients with CML were treated by various concentrations of CA. Flow cytometry was employed to measure the apoptosis of K562 cells and primary CML bone marrow MNC. Western blot was used to determine the expression of C-MYC and the phosphorylation of CrkL in K562 cells, and real-time polymerase chain reaction (real-time PCR) was used to quantify the expression of BCR-ABL mRNA in K562 cells. The results indicated that CA induced the apoptosis of K562 cells in a time- and dose-dependent manner. CA induced apoptosis of CML MNC dose-dependently. CA inhibited the expression of BCR-ABL mRNA and C-MYC, reduced CrkL phosphorylation levels in K562 cells. It is concluded that CA induces apoptosis of CML cells in vitro. Down-regulation of the expression and function of BCR-ABL may be one of its most important anti-leukemia mechanisms.

OBJECTIVETo investigate the correction of secondary breast deformities after removement of injected polyacrylamide hydrophilic gel (PAHG).
METHODSFrom March 2003 to March 2008, 100 patients with bilateral breast augmentation with injected PAHG underwent operation to remove the PAHG. The age of patients ranged from 35 to 50 years. Ultrasound and MRI were performed before operation to show the distribution of PAHG and the muscle infiltration around the PAHG. According to the PAHG distribution, muscle infiltration, skin elasticity, infection and PAHG residue, the patients were treated respectively with breast implants at the same stage or at the second stage, or without implants.
RESULTSThe patients were followed up for 3 months to 3 years. The percentage of satisfactory, median satisfactory and dissatisfactory was 90%, 9%, and 1%. In the median satisfactory group, 3 breasts in 3 cases showed slight capsular contracture (Baker II), 8 implants in 6 cases were palpable on the lower pole of the breasts. The middle-aged patient in dissatisfactory group was not satisfied with the high-projected implants shape which were chosen by herself and placed at the second stage. Then implants were removed. There was no complication of implant hernia, infection, wound disruption, or asymmetry.
CONCLUSIONSThe secondary breast deformities could be corrected by breast augmentation with implants. Both breast appearance and the psychological affection can be improved.

Objective To explore chromobox protein homolog 2 (CBX2) expressions in relation to clinical features of patients and elucidate its role in the progression of hepatocellular carcinoma.Methods Using the Cancer Genome Atlas (TCGA) database,R language was used to analyze the distribution of differentially expressed mRNA in hepatocellular carcinoma.The different expression of CBX2 in HCC and adjacent tissues and its relationship with survival and clinical characteristics of patients were further analyzed.The expression of CBX2 in liver tissues,liver cancer tissue,and L02,HepG2 and SMMC-7721 cell lines was detected by real time-PCR and western blot.The expression of CBX2 was interfered by siRNA in hepatoma cell line.MTT,colony formation,transwell assays,and flow cytometry were used to identify the proliferation,apoptosis,invasion and clone-formation ability of HepG2 and SMMC-7721 cells after CBX2 down-regulation.According to the different data,t-test,ANOVA,chi-square test,and COX regression model were used for statistical analysis.Survival curve was plotted through Kaplan-Meier method.Results TCGA public database analysis showed that the expression of CBX2 mRNA in hepatocellular carcinoma tissues (7.296 ± 1.6115) was significantly higher than normal liver tissues (4.706 ± 0.940) (P =0.000).In addition,the overall survival time of patients with low CBX2 mRNA expression was significantly longer than that of patients with high CBX2 mRNA expression [(5.971 ± 0.411) years vs.(4.650 ± 0.503) years,P =0.001].The expression level of CBX2 mRNA was correlated with the pathological TNM stage (P =0.025) and differentiation degree (P < 0.001) of liver cancer.COX regression analysis showed that CBX2 mRNA expression was an independent predictor of patient survival (P =0.013).siRNA was transfected and compared with the blank control group.The transgenic ability of HepG2 and SMMC-77221 cells decreased significantly at 72h (P < 0.05) and 96h (P < 0.05),and the apoptosis rate (11.430% ± 0.215%) was higher than blank control group (6.6 00% ± 0.170%) (P =0.003).The number of invasive cells ((both P < 0.05) and relative colony forming cells ((both P < 0.001) were significantly decreased.In 20 cases of tissue samples,the expression of CBX2 protein (relative expression level 3.020 ±0.269) in liver cancer was higher than that in adjacent tissues (relative expression level 0.886±0.065) (P < 0.001).The overall survival time of patients with low CBX2 expression in liver cancer was longer than that of patients with high expression [(3.670 + 0.576) years vs.(0.834 + 0.153) years,P =0.004].Conclusion An evident high expression of CBX2 is an independent poor prognostic factor in hepatoma.Down-regulation of CBX2 expression can inhibit the progression of liver cancer.Therefore,CBX2 may be a prognostic biomarker and a new target for HCC treatment.
