Objective:To analyze the expression of tuftelin protein (TUFT1) and its clinical value in hepatocellular carcinoma (HCC)-related liver cancer tissues.Methods:The biological information data of TUFT1 mRNA expression in liver cancer and non-cancer tissues were analyzed from the TCGA and Oncomine database. After the approval of the ethics committee, the self-pairing method was used to collect the postoperative cancer and para-carcinoma tissues of 132 HCC cases hospitalized between January 2009 and December 2014. Tissue microarray and immunohistochemistry (IHC) were used to analyze the expression of TUFT1 in liver tissues. According to IHC staining, liver cancer was divided into high TUFT1 and low/no expression group. Combined with clinical data, the clinicopathological characteristics were statistically analyzed between and within the groups. The 5-year overall survival (OS) and disease-free survival (DFS) was analyzed by correlation analysis.Results:IHC staining showed that TUFT1 in cancer tissue was localized in the cytoplasm and cell membrane, and its positive expression rate was significantly higher in the liver cancer group (87.1%) than the para-carcinoma group (64.4%) ( χ2 = 18.563, P < 0.001). TUFT1 expression intensity in patients with liver cancer was significantly correlated with HBeAg positive ( χ2 = 4.080, P = 0.043), tumor size ( χ2 = 9.388, P = 0.002), vascular invasion ( χ2 = 14.885, P < 0.001), TNM stage ( χ2 = 13.516, P < 0.001) and ascites ( χ2 = 5.940, P = 0.015). TUFT1 high expression was negatively correlated with OS and DFS ( P < 0.001). Conclusion:The overexpression of TUFT1 is closely related to HBV replication, vascular invasion and poor prognosis, and it is expected to become a useful marker for liver cancer diagnosis and prognosis.

Lung cancer which represents characteristics of a heavy disease burden, a large proportion of advanced lung cancer and a low five-year survival rate is a threat to human health. It is essential to implement population-based lung cancer screening to improve early detection and early treatment. The National Lung Screening Trial (NLST) demonstrated that screening with low dose helical computed tomography (LDCT) may decrease lung cancer mortality, which brings hope for the early diagnosis and treatment of lung cancer. In recent years, great progresses have been made on research of lung cancer screening with LDCT. However, whether LDCT could be applied to large population-based lung cancer screening projects is still under debate. In this paper, we review the recent progresses on history of lung cancer screening with LDCT, selection of high-risk individuals, management of pulmonary nodules, performance of screening, acceptance of LDCT and cost-effectiveness.

Objective:To compare the acceptance of urine self-sampling, vaginal self-sampling and physician sampling in cervical cancer screening.Methods:Questionnaire surveys were conducted in women attending cervical cancer screening in Xiangyuan County and Yangcheng County in Shanxi Province from July to November 2015 and from October to December 2018. Both surveys included the following three parts: feelings and acceptance of women in urine self-sampling, vaginal self-sampling and physician sampling, and the ease evaluation of two self-samplings.Results:There were 3 485 questionnaires were collected finally. The proportions of women felt embarrassed in urine self-sampling, vaginal self-sampling and physician sampling were 2.3% (81/3 472), 7.1% (247/3 472) and 8.6% (299/3 472), and 1.3% (46/3 472), 9.7%(3 37/3 472) and 14.9% (518/3 472) of women felt uncomfortable, and 1.0% (35/3 469), 8.5% (295/3 469) and 15.3% (531/3 469) felt pain, and 98.3% (3 334/3 393), 96.3% (3 267/3 393) and 99.0% (3 360/3 393) thought that the sampling were conducted properly ( P<0.05). Based on the feeling during sample collection, 61.2% (1 876/3 064), 39.1% (1 199/3 064) and 66.5% (2 037/3 064) women were willing to use the corresponded sampling methods in cervical cancer screening, respectively ( P<0.05). If the accuracy was the same, there were 31.8% (1 109/3 485) women preferred self-sampling and 68.2% (2 376/3 485) preferred physician sampling for cervical cancer screening. Meanwhile, 23.5% (820/3 482) preferred vaginal self-sampling in comparison with 76.5% (2 662/3 482) for urine self-sampling in cervical cancer screening. 86.5% (3 007/3 478) of the women thought urine self-sampling was very easy, comparing 40.9% (1 423/3 478) for vaginal self-sampling. Conclusions:The bad feeling of women during urine self-sampling is less common and less serious than those during physician sampling and vaginal self-sampling, and the acceptance for physician sampling is highest, following by urine self-sampling and vaginal self-sampling. Urine self-sampling is much easier than vaginal self-sampling.

Objective: To evaluate the clinical efficacy of modified lateral window for maxillary sinus floor augmentation (MSFA). Methods: Fifty-five patients who visited the Stomatology Hospital Affiliated to Zhejiang University School of Medicine between June 2012 and October 2014 were enrolled in the study. Patients underwent MSFA with Bio-Oss grafts based on modified access window. During the operation the vertical height of the bony window was reduced from 6-8 mm of conventional oval window to 4-5 mm of slot-shaped window. The sinus membrane was detached completely via the lateral access and large particle Bio-Oss graft was placed in the sub-mucosal space. The implant survival, graft height, graft volume and resorption rates were measured. Intra-op and post-op complications were recorded. Results: There were 86 implants inserted. The 2-4 year cumulative survival rates were 97.67% by implant-based analysis and 96.36% by patient-based analysis. The residual bone height was (4.7±2.6) mm and bone width was (8.4±2.7) mm. The bone height of implantation site immediately after operation was (16.1±2.5) mm and it was (16.2±2.2) mm at restoration. The bone heights at 1 and 2 years after operation were (14.9±2.5) mm and (13.6±2.6) mm, respectively. The graft height was (10.6±2.8) mm and the graft volume was (1569±745) mm³ immediately after operation. The resorption rate of graft height 6 months after operation was 3.79% and that of graft volume was 7.87%. The 1-year accumulative resorption rate of graft height was 6.63% and that of graft volume was 10.89%. The 2-year accumulative resorption rate of graft height was 7.58% and that of graft volume was 15.26%. Small membrane perforation during MSFA was observed in 5 cases and all were successfully repaired by a collagen Bio-Gide membrane. Conclusion: The modified lateral technique obtains high implant survival rate, excellent graft stability and low complication rate at 2-4 year clinical follow-up, indicating that it is a safe, predictable and minimally invasive surgical method for severe atrophic maxillary posterior dentition.

Many people affected by fragile X syndrome (FXS) and autism spectrum disorders have sensory processing deficits, such as hypersensitivity to auditory, tactile, and visual stimuli. Like FXS in humans, loss of Fmr1 in rodents also cause sensory, behavioral, and cognitive deficits. However, the neural mechanisms underlying sensory impairment, especially vision impairment, remain unclear. It remains elusive whether the visual processing deficits originate from corrupted inputs, impaired perception in the primary sensory cortex, or altered integration in the higher cortex, and there is no effective treatment. In this study, we used a genetic knockout mouse model (Fmr1^KO), in vivo imaging, and behavioral measurements to show that the loss of Fmr1 impaired signal processing in the primary visual cortex (V1). Specifically, Fmr1^KO mice showed enhanced responses to low-intensity stimuli but normal responses to high-intensity stimuli. This abnormality was accompanied by enhancements in local network connectivity in V1 microcircuits and increased dendritic complexity of V1 neurons. These effects were ameliorated by the acute application of GABA_A receptor activators, which enhanced the activity of inhibitory neurons, or by reintroducing Fmr1 gene expression in knockout V1 neurons in both juvenile and young-adult mice. Overall, V1 plays an important role in the visual abnormalities of Fmr1^KO mice and it could be possible to rescue the sensory disturbances in developed FXS and autism patients.
