Objective: To evaluate the value of early identification and endovascular treatment of iliac vein compression syndrome (IVCS), with or without deep vein thrombosis (DVT). Materials and Methods: Three groups of patients, IVCS without DVT (group 1, n = 39), IVCS with fresh thrombosis (group 2, n = 52) and IVCS with non-fresh thrombosis (group 3, n = 34) were detected by Doppler ultrasonography, magnetic resonance venography, computed tomography or venography. The fresh venous thrombosis were treated by aspiration and thrombectomy, whereas the iliac vein compression per se were treated with a self-expandable stent. In cases with fresh thrombus, the inferior vena cava filter was inserted before the thrombosis suction, mechanical thrombus ablation, percutaneous transluminal angioplasty, stenting or transcatheter thrombolysis. Results: Stenting was performed in 111 patients (38 of 39 group 1 patients and 73 of 86 group 2 or 3 patients). The stenting was tried in one of group 1 and in three of group 2 or 3 patients only to fail. The initial patency rates were 95% (group 1), 89% (group 2) and 65% (group 3), respectively and were significantly different (p = 0.001). Further, the six month patency rates were 93% (group 1), 83% (group 2) and 50% (group 3), respectively, and were similarly significantly different (p = 0.001). Both the initial and six month patency rates in the IVCS patients (without thrombosis or with fresh thrombosis), were significantly greater than the patency rates of IVCS patients with non-fresh thrombosis. Conclusion: From the cases examined, the study suggests that endovascular treatment of IVCS, with or without thrombosis, is effective.

Berberine, a common isoquinoline alkaloid, has been shown to possess anti-cancer activities. However, the underlying molecular mechanisms are still not completely understood. In the current study, we investigated the effects of berberine on cell growth, colony formation, cell cycle distribution, and whether it improved the anticancer efficiency of cisplatin and doxorubicin in human breast cancer estrogen receptor positive (ER+) MCF-7 cells and estrogen receptor negative (ER-) MDA-MB-231 cells. Notably, berberine treatment significantly inhibited cell growth and colony formation in the two cell lines, berberine in combination with cisplatin exerting synergistic growth inhibitory effects. Accompanied by decreased growth, berberine induced G1 phase arrest in MCF-7 but not MDA-MB-231 cells. To provide a more detailed understanding of the mechanisms of action of berberine, we performed genome-wide expression profiling of berberine-treated cells using cDNA microarrays. This revealed that there were 3,397 and 2,706 genes regulated by berberine in MCF-7 and MDA-MB-231 cells, respectively. Fene oncology (GO) analysis identified that many of the target genes were involved in regulation of the cell cycle, cell migration, apoptosis, and drug responses. To confirm the microarray data, qPCR analysis was conducted for 10 selected genes based on previously reported associations with breast cancer and GO analysis. In conclusion, berberine exhibits inhibitory effects on breast cancer cells proliferation, which is likely mediated by alteration of gene expression profiles.

Estrogens are considered the major breast cancer risk factor, and the carcinogenic potential of estrogens might be attributed to DNA modification caused by derivatives formed during metabolism. $17{\beta}$-estradiol ($E_2$), the main steroidal estrogen present in women, is metabolized via two major pathways: formation of 2-hydroxyestradiol (2-OH $E_2$) and 4-hydroxyestradiol ($4-OH\;E_2$) through the action of cytochrome P450 (CYP) 1A1 and 1B1, respectively. Previous reports suggested that $2-OH\;E_2$ has putative protective effects, while $4-OH\;E_2$ is genotoxic and has potent carcinogenic activity. Thus, the ratio of $2-OH\;E_2/4-OH\;E_2$ is a critical determinant of the toxicity of $E_2$ in mammary cells. In the present study, we investigated the effects of berberine on the expression profile of the estrogen metabolizing enzymes CYP1A1 and CYP1B1 in breast cancer MCF-7 cells. Berberine treatment produced significant induction of both forms at the level of mRNA expression, but with increased doses produced 16~ to 52~fold greater induction of CYP1A1 mRNA over CYP1B1 mRNA. Furthermore, berberine dramatically increased CYP1A1 protein levels but did not influence CYP1B1 protein levels in MCF-7 cells. In conclusion, we present the first report to show that berberine may provide protection against breast cancer by altering the ratio of CYP1A1/CYP1B1, could redirect $E_2$ metabolism in a more protective pathway in breast cancer MCF-7 cells.

Hao Peng,Congying Huang,Xiaogang Zheng,Jing Wen 한국공업화학회 2022 Journal of Industrial and Engineering Chemistry Vol.106 No.-

The low-cost and highly-efficient photocatalysts for solar-light induced water splitting had drawn greatattention to develop the renewable hydrogen economy. To enhance the solar-light driven H2 evolution ofMn0.5Cd0.5S, Mn0.5Cd0.5S was modified by S,N-codoped carbon (3-MCS/SN-C) via the in-situ sulfurizationat high temperature. In contrast with Mn0.5Cd0.5S (11.13 mmol g1 h1) and S-doped g-C3N4(0.35 mmol g1 h1), the optimal 3-MCS/SN-C with a mass ratio of Mn0.5Cd0.5S to S,N-codoped carbonof 1:3 exhibited the best H2 evolution rate of 27.58 mmol g1 h1 and an apparent quantum yield of27.43% at 400 nm. The photo-corrosion induced to the decreased H2 evolution capacity of 3-MCS/SN-Cfrom 131.13 to 126.52 mmol g1 after five cycles of 5 h. S,N-codoped carbon could efficiently capture visiblelight and absorb the photons, leading to the efficient transformation and separation of photogeneratedcarriers at the junction interface between Mn0.5Cd0.5S and S,N-codoped carbon.

In this study, we evaluated the effect of additionof non-volatile compounds (sodium sulfite, tartaric acid,tannin, and glucose) on the rheological properties, releaseof aroma compounds, and color of the red wine. Whiledetermining the rheological properties of the supplementedsamples, non-Newtonian fluidic and shear-thinningbehavior of samples was noticed. The viscosity of thesesamples was found in negative correlation with the dose ofaddition of various non-volatile substances. The aromaprofile of red wine after additions showed the change in therelease of the nine key aroma compounds. Among themethyl hexanoate, phenylethyl alcohol, octanoic acid, diethylsuccinate, and ethyl octanoate were profoundly increased. Further, the color of red wines was improved in the presenceof tartaric acid and tannin. Overall, supplementationof various substances during storage period of three differentwines could enormously affect the sensory characteristicsin a dose dependent manner.

Serum Zinc Status and Helicobacter Pylori Infection in Gastric Disease Patients

Zhang, Wen-Hua,Wu, Xiao-Jing,Niu, Jing-Xiu,Yan, Hao,Wang, Xin-Zhuo,Yin, Xiao-Dong,Pang, Yan Asian Pacific Journal of Cancer Prevention 2012 Asian Pacific journal of cancer prevention Vol.13 No.10

The role of Helicobacter pylori status and serum zinc value in gastric disease patients and healthy controls were investigated. Cases used in this work were 45 gastric cancer patients, 44 with peptic ulcers, 52 suffering gastritis and 64 healthy controls, all diagnosed histologically with the controls undergoing medical checkups. Helicobacter pylori status and serum levels of Zn were determined by 13C-urea breath test and flame atomic absorption spectrophotometer, respectively. Our study showed that Helicobacter pylori infection has no change in gastritis, peptic ulcer and gastric cancer group, on the contrast, serum levels of Zn were significantly reduced in gastritis, peptic ulcer and gastric cancer group, compared with healthy controls, and the higher the Zn levels are, the more increased risk of gastric cancer. Helicobacter pylori infection is a cause of gastritis, peptic ulcers and even gastric cancer, while serum zinc level is an indicator of protection of gastric membranes against damage.

Effect of Sand Particle Size on Hydraulic-Mechanical Behavior of Bentonite-Sand Mixtures

Tian-Hao Lu,Wen-Jing Sun,Ke Liu,Yun-Zhi Tan 대한토목학회 2022 KSCE JOURNAL OF CIVIL ENGINEERING Vol.26 No.8

Bentonite-sand mixtures can be used as the base material of engineered barriers in deep high-level radioactive waste geological repositories. Swelling, compression, and permeability tests were conducted out on bentonite-sand mixtures with 30%, 50%, 70% and 85% sand content. Influence of sand content and particle size on the deformation and permeability characteristics of bentonite-sand mixtures were analyzed. The sand particle size affects the deformation characteristics by influencing the vertical stress required to form a sand skeleton, and the skeleton’s stability. When the sand content is less than the critical sand content, bentonite-sand mixtures cannot form a sand skeleton, and particle size has no effect on their characteristics. When the sand content is greater than the critical sand content and the vertical stress exceeds the initial deviation stress, a sand skeleton forms. In this case, smaller the sand particle size, lesser will be the vertical stress required to form a sand skeleton, and more the swelling of bentonite-sand mixtures. Further, more uniform particle size, more stable will be its structure and lesser the compressibility of bentonite-sand mixtures. The hydraulic conductivity is related to the flow area and the seepage path length, and particle size has no obvious effect on either with the same sand content. Therefore, the sand particle size has no obvious effect on mixtures’ permeability.

Stratification Analysis and Case-control Study of Relationships between Interleukin-6 Gene Polymorphisms and Cervical Cancer Risk in a Chinese Population

Shi, Wen-Jing,Liu, Hao,Wu, Dan,Tang, Zhen-Hua,Shen, Yu-Chen,Guo, Lin Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.17

Interleukin-6 (IL-6), a central proinflammatory cytokine, maintains immune homeostasis and also plays important roles in cervical cancer. Therefore, we aimed to evaluate any associations of IL-6 gene polymorphisms at positions -174 and -572 with predisposition to cervical cancer in a Chinese population. The present hospital-based case-control study comprised 518 patients with cervical cancer and 518 healthy controls. Polymorphisms of the IL-6 gene were genotyped by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). Patients with cervical cancer had a significantly higher frequency of the IL-6 -174 CC genotype [odds ratio (OR) =1.52, 95% confidence interval (CI) = 1.06-2.19; p=0.02], IL-6 -572 CC genotype (OR =1.91, 95% CI = 1.16-3.13; p=0.01) and IL-6 -174 C allele (OR =1.21, 95% CI = 1.02-1.44; p=0.03) compared to healthy controls. When stratifying by the FIGO stage, patients with III-IV cervical cancer had a significantly higher frequency of IL-6 -174 CC genotype (OR =1.64, 95% CI =1.04-2.61; p=0.04). The CC genotypes of the IL-6 gene polymorphisms at positions -174 and -572 may confer a high risk of cervical cancer. Additional studies with detailed human papillomavirus (HPV) infection data are warranted to validate our findings.

Zhang Xiao-wen,Li Jing,Hou Wen-Bin,Jiang Yue,Zheng Ruo-Xiang,Xu De-hao,Shen Chen,Robinson Nicola,Liu Jian-Ping 한국한의학연구원 2023 Integrative Medicine Research Vol.12 No.1

Background: To explore the effectiveness and safety of Chinese herbal medicine (CHM) for drug-induced liver injury (DILI) in patients with human immunodeficiency virus (HIV)/acquired immunodeficiency syn- drome (AIDS). Methods: A systematic search was made of eight databases (Pubmed, Cochrane Library, Web of Science, Embase, CNKI, Wanfang, VIP, Sinomed) and two trial registries (WHO ICTRP, ClinicalTrials.gov) from in- ception to September 2022. The effect size was presented as risk ratio (RR) or mean difference (MD) with their 95% confidence interval (CI). The Cochrane Risk of Bias and Grading of Recommendations, Assess- ment, Development and Evaluations (GRADE) tools were used for quality appraisal. Results: Ten randomized controlled trials (RCTs) involving 732 participants were included. Comparing CHM alone with routine treatment, the CHM group showed lower aspartate aminotransferase (MD = -11.47 U/L, 95%CI[-13.05, -9.89], low certainty), lower alanine aminotransferase (MD = -2.68 U/L, 95%CI[-4.27, - 1.08], low certainty), lower total bilirubin (MD = -4.31 mmol/L, 95%CI[-5.66, -2.96], low certainty), lower bilirubin direct (MD = -3.19 mmol/L, 95%CI[-3.87, -2.51], low certainty), and higher effective rate (assessed by symptoms and liver indicators) (RR = 1.13, 95%CI[1.06, 1.20], low certainty). A significant difference was also found in CHM plus routine treatment versus routine treatment in the previous outcomes. No signif- icant difference was found on helper T cells among these comparisons. Only one RCT reported safety of CHM and found no adverse reaction during the trial. Conclusions: CHM may improve the liver function indices and effective rate for HIV/AIDS patients with DILI. However, the sample size was small and quality was low. Larger-samples of high-quality trials are needed.
