Objective: To investigate the relationship between the efficacy and safety of different doses of thalidomide (Thal) plus dexamethasone (Dex) as the initial therapy in elderly patients with newly diagnosed multiple myeloma (MM). Methods: Clinical data of 28 elderly patients with newly diagnosed MM who underwent the TD regimen as the initial therapy were analyzed retrospectively. The patients were divided into two groups according to the maximal sustained dose of Thal: lower dose (group A) and higher dose (group B). The overall response rate (ORR), progression free survival (PFS), overall survival (OS), and adverse events (AES) were compared between the two groups. Results: A total of 28 patients were followed up with a median of 18 months. The ORR was 60.1%. The median response time and PFS were 2.0 and 17.0 months, respectively. The mean sustained dose of Thal in group B was significantly higher than group A (292.9 mg v 180.4 mg, P=0.01). There was no significantly difference in ORR (57.1% v 64.3%, P=1.00) and PFS (9.63months v 17.66 months, P=0.73) between groups A and B. During the follow up, only five patients died (<40%) and, therefore, median OS values were not available. It is estimated, however, that the mean survival time in the two groups was 35.6 and 33.4 months (P>0.05), respectively. All of the patients tolerated the treatment well. The incidence of AES in patients with a grading above 3 in group B was significantly higher than in group A (P=0.033). Conclusions: The TD regimen results in a high response rate and manageable AES as the initial therapy in elderly patients with MM. TD should be considered as the front line regimen for the treatment of elderly patients with MM in areas with financial constraints. The clinical response can be achieved at a low dose Thal with minimal toxicity.

Glass fiber felts (GFFs) coated with reduced graphene oxide (RGO)/phenolic resin (PF) binder was prepared by in-situ reduction reaction, subsequently spraying, and curing process. The effects of the RGO content on the thermal, antiablative, hydrophobic, and mechanical properties of GFFs were studied. Fourier-transform infrared (FT-IR) spectra, X-ray diffraction (XRD) and electronic differential system (EDS) analysis revealed that the graphene oxide (GO) was reduced to RGO by phenol during the in-situ polymerization. Thermogravimetry (TG) and DTG analytical diagram demonstrated that the thermal stability of GFFs was also significantly improved with the addition of GO due to the barrier effect of the lamellar structure. Also, by addition of 0.4 wt% of GO, hydrophobicity was improved by 39 % and the tear strength was improved by 57 % owning to its unique structure and the effective external load transfer. Moreover, the compatibility with PF matrix was improved, endowing good anti-ablative, excellent hydrophobicity and mechanical properties for GFFs.

Aims: Early diagnosis is important for cervical cancer treatment. This study aimed to characteriz the microRNA profile and target gene protein levels of cervical cancers in Uygur women for application in early diagnosis. Methods: The profiles of miRNA in cervical cancer and chronic cervicitis were analyzed with miRNAmicroarray V4.0. The expression of miR-101 was detected by real-time PCR and locked nucleotide acid in situ hybridization (LNA-ISH). Cox-2 protein levels were assessed by immunohistochemistry. Results: The microarray identified a set of 12 miRNAs significantly decreased in cervical cancer in comparison to the control group. Quantitative RT-PCR analysis showed miR-101 to be significantly downregulated in cancer tissues (p<0.05) while LNA-ISH showed miR-101 positive rates of 80% (20/25) and 8% (5/25) (p<0.05) in the control and cervical cancer groups. Cox-2 positive rates of cervical cancer and control groups were 84% (21/25) and 8% (2/25) (p<0.05). Conclusions: Use of down-regulation of miR-101 and up-regulation of Cox-2 as markers may play a role in early diagnosis of cervical cancer in Uygur women.

Forkhead-box (FOX) transcription factors comprise a large gene family that contains more than 50 members in man. Extensive studies have revealed that they not only have functions in control of growth and development, but also play important roles in different diseases, especially in cancer. However, biological functions for most of the members in the FOX family remain unknown. In the present study, the expression of 39 FOX genes in 48 kinds of cancer was mined from the Gene Expression Atlas database of European Bioinformatics Institute. The analysis results showed that some FOX genes demonstrate overlapping expression in various cancers, which suggests particular biological functions. The pleiotropic features of the FOX genes make them excellent candidates in efforts aimed to give medical treatment for cancers at the genetic level. The results also indicated that different FOX genes may have the synergy or antagonistics effects in the same cancers. The study provides clues for further functional analysis of FOX genes, especially for the pleiotropic biological functions and crosstalk of FOX genes in human cancers.

Aims: Late recurrence (> 2 years) after liver resection of hepatocellular carcinoma (HCC) is usually considered as multi-centric tumors or de novo cancer formation. We aimed to investigate risk factors, patterns and outcomes of late recurrence after HCC resection. Methods: From a multicenter database from 2001 to 2015, 734 patients who were alive and recurrence-free at 2 years after curative resection of initial HCC were enrolled into this retrospective study. Univariate and multivariate Cox-regression analysis were used to identify independent risk factors of late recurrence. Patterns, treatments and outcomes of late recurrence were investigated and analyzed. Results: During a median follow-up of 78.0 months after surgery, 303 patients (41.3%) developed late recurrence. Multivariate analysis revealed that cirrhosis, macroscopic vascular invasion, satellites, and tumor size > 5cm were independent risk factors of late recurrence. Among them, 273 (90.1%) were sole intrahepatic recurrence, 30 (9.9%) were concurrent intrahepatic and extrahepatic recurrence, and none of them was sole extrahepatic recurrence; 165 (54.4%) patients received curative treatments for recurrent HCC, including re-resection, transplantation and local ablation. Multivariate analysis showed regular postoperative surveillance and receiving curative treatments were two independent protective factors of prolonging survival for those patients with late recurrence. Conclusions: Late recurrence is correlated with cirrhosis and certain tumor-related characteristics of initial HCC. The patterns of late recurrence suggest that postoperative surveillance after 2 years of surgery could be adjusted and more targeted. Regular postoperative surveillance improves the probability to receive curative treatments again, yielding to better outcomes for patients with late recurrence.

The present systematic review and meta-analysis was conducted to assess any association between breastfeeding and the risk of ovarian cancer. A systematic search of published studies was performed in PUBMED and EMBASE and by reviewing reference lists from retrieved articles through March 2013. Data extraction was conducted independently by two authors. Pooled relative risk ratios were calculated using random-effect models. Totals of 5 cohort studies and 35 case-control studies including 17,139 women with ovarian cancer showed a 30% reduced risk of ovarian cancer when comparing the women who had breastfed with those who had never breastfed (pooled RR = 0.70, 95% CI: 0.64-0.76; p = 0.00), with significant heterogeneity in the studies (p = 0.00; I2 = 76.29%). A significant decreasd in risk of epithelial ovarian cancer was also observed (pooled RR = 0.68, 95% CI: 0.61-0.76). When the participants were restricted to only parous women, there was a slightly attenuated but still significant risk reduction of ovarian cancer (pooled RR = 0.76, 95% CI: 0.69-0.83). For total breastfeeding duration, the pooled RRs in the < 6 months, 6-12 months and > 12 months of breastfeeding subgroups were 0.85 (95% CI: 0.77-0.93), 0.73 (95% CI: 0.65-0.82) and 0.64 (95%CI: 0.56-0.73), respectively. Meta-regression of total breastfeeding duration indicated an increasing linear trend of risk reduction of ovarian cancer with the increasing total breastfeeding duration (p = 0.00). Breastfeeding was inversely associated with the risk of ovarian cancer, especially long-term breastfeeding duration that demonstrated a stronger protective effect.
