For the first time, CMOS inverters with different numbers of vertically stacked junctionless (JL) nanosheets (NSs) are demonstrated. All fabrication steps were below 600 °C, and 8-nm thick poly-Si NSs with smooth surface roughness were formed by a dry etching process. Compared to single channel devices, stacked n/p-channel FETs exhibit higher on-current with low leakage current. Furthermore, a common-gate process was performed for the fabrication of CMOS inverters. By adjusting the NS layer numbers for n/pFETs, respectively, the voltage transfer characteristics (VTCs) of the CMOS inverter can be matched much better to reduce the noise margin due to on-current matching without area penalty. This work experimentally demonstrates a new configuration of CMOS inverters on stacked NSs, which is promising for System-on-Panel (SoP) and 3D-ICs applications.

- Abstract
OBJECTIVE: This study aims to survey medical staff’s acceptance of online Mindfulness-Based Stress Reduction (MBSR) during the Novel Coronavirus Pneumonia (NCP), and to know some information of physical and emotional response of those medical staff who worked at the forefront of COVID-19, through the playback amount of the online MBSR training. MATERIALS AND METHODS: Considering the working environment of medical staff in forefront of NCP, we designed and recorded MBSR audio album including 13 sessions, covering 24 hours of a day, then sent the album to medical staff who had been working in Wuhan, Hubei province, China. We collected the playback amount in each session on February 10th and February 24th, which were one week and three weeks after the album was finished. RESULTS: On February 10th and February 24th, there were separately 5778 and 10640 times of broadcasting. The highest broadcasting frequency session was at 5:00 am, followed by 7:00 am. The least broadcasting frequency sessions were 17:00 pm and 19:00 pm. The broadcasting amount in the 6 periods of the night (from 21:00 pm to 7:00 am) was significantly higher than those in the daytime (from 9:00 am to 19:00 pm), with a statistical difference. The tendency of the amount of playback was consistent, which was not affected by the specific content of the mindfulness exercises. CONCLUSIONS: Online MBSR exercises were well accepted by medical staff in the COVID-19. It may help them relax and reduce the risk of stress reactions. During the NCP, medical staff may have different degrees of sleep and emotional problems, which need to be paid more attention to. [ABSTRACT FROM AUTHOR]

PHENOLS ,CULTIVARS ,PLUM ,VITAMIN C ,SYRINGIC acid - Abstract
The physiochemical parameters and antioxidant properties of plum cultivars, grown in subtropical regions of China are little known. However, in this comparative study, these properties of 6 landraces and 7 introduced cultivars showed evaluated. The major nonvolatile constituents were a significant difference among cultivars. Color parameter values were strongly influenced by cyanidin 3-O-glucoside and cyanidin 3-O-rutinoside. Remarkably high antioxidant activity, high total phenolic, and ascorbic acid contents were found in black or purple flesh genotypes. Catechinic acid, the most important phenolic acid in Japanese plum, together with vanillic acid, caffeic acid and syringic acid, accounted for > 96% of the total phenolic content. The total phenolics and ascorbic acid concentration revealed significant contributions to antioxidant capacity detected by α, α-diphenyl-β-picrylhydrazyl (DPPH), (r = 0.78**, 0.73**) and ferric reducing antioxidant power (FRAP) (r = 0.74**, 0.57*). Moreover, there was a clear correlation between the total phenolic compounds and the ascorbic acid content (r = 0.76**). Comparison of physicochemical characteristics and antioxidant profiles revealed that both introduced cultivars and landraces had good adaptability in the subtropical region. [ABSTRACT FROM AUTHOR]

- Abstract
OBJECTIVE: The underlying mechanism of long non-coding RNA (lncRNA) in lung adenocarcinoma (LAC) has not been fully understood yet. Hence, this study aimed to determine the biological function of LINC00324 in LAC and to provide a novel diagnostic and therapeutic target for it. PATIENTS AND METHODS: The expression level of LINC00324 in 87 paired LAC tumor tissues and matched para-tumor tissues was detected using quantitative Real Time-Polymerase Chain Reaction (qRT-PCR). Cell counting kit-8 (CCK-8) assay was employed to analyze the cell proliferative ability, whereas flow cytometry was performed to detect cell apoptotic rate. Cell metastasis change was measured using wound-healing assay and transwell assay. Luciferase reporter gene assay and Western blotting analysis were utilized to investigate the underlying mechanism of LINC00324 in LAC. RESULTS: LINC00324 was highly expressed in LAC tissues compared with the para-tumor samples. Identically, the expression level of LINC00324 was significantly higher in LAC cell lines. The over-expression of LINC00324 promoted cell proliferation and inhibited cell apoptosis of LAC cells, while knockdown of LINC00324 presented the opposite effect. Up-regulation of LINC00324 accelerated cell migration and invasion, but down-regulation of LINC0324 decreased cell metastasis of LAC cells. Furthermore, miR-615-5p was found to be regulated by LINC00324 and inhibited AKT1 expression, indicating that LINC00324 promoted cell progression via affecting the miR-615-5p/AKT1 pathway. CONCLUSIONS: LINC00324 was significantly over-expressed in LAC tissues and cells. It promoted proliferation and metastasis but inhibited cell apoptosis of LAC cells via sponging miR- 615-5p to promote AKT1 expression. Our results demonstrated LINC00324 as a novel diagnostic and therapeutic target for LAC. [ABSTRACT FROM AUTHOR]

Zr doped TiO2 photocatalyst was prepared using the sol-gel method with a mixed template of polyethylene glycol (PEG) and cetytrimethylammonium bromide (CTAB) at low temperature. The samples were characterised by X-ray diffraction (XRD), transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FTIR), X-ray photoelectron spectroscopy (XPS), UV-visible spectroscopy (UV-vis) and the nitrogen adsorption experiment. Zr doped TiO2 photocatalyst showed a relatively elliptic shape with a size distribution of 9·5±0·5 nm. The average pore size and surface area were 4·95 nm and 138 m2 g-1 respectively. X-ray photoelectron spectroscopy revealed that the binding energy of Zr 3d5/2 electrons coincided with the Zr2O3. The Zr-O vibration band can be seen at 653 cm-1 in the 8% Zr doped TiO2 before calcinations. UV-vis absorption spectra exhibited that the absorption edge of Zr doped TiO2 shifted to the lower energy region. The photocatalytic activity of samples was determined by using 3I-→I3-+2e- as a model reaction. The results showed that the doping of TiO2 with zirconium showed the effect of increasing the photocatalytic activity and did not show any obvious effect in changing the crystal structure of anatase TiO2 in the scope that the content of zirconium in TiO2 was less than 8%.

2 , and Mo2 B particles reinforced Fe-based composite coatings were fabricated by laser cladding process. The effects of Molybdenum (Mo) on the microstructure and wear properties of the coatings were investigated. The results show that block-like or cuboidal TiB2 , Mo2 B and flower-like (Ti, Mo)C ceramics reinforcements were formed in the coatings. The size of reinforcements reduced with the increasing of FeMo70 . However, cracks were found in the coating, while the addition of FeMo70 exceeded 9 wt %. The laser cladding coating presented a good wear resistance with a 9 wt % addition of FeMo70 . With the increasing of FeMo70 , the coatings enhanced the capability of resisting microcutting, microplowing, and surface plastic deformation. [ABSTRACT FROM AUTHOR]- Published

- Abstract
Objective: Investigate the current situation of lung cancer cough diagnosis and treatment and the awareness of related issues among Chinese medical providers. Methods: Doctors, nurses, pharmacists from the oncology department, respiratory department, or general department were investigated using an electronic questionnaire from January 29 to March 29, 2021. There were 25 questions about lung cancer in the questionnaire. The questionnaire was including the most common accompanying symptoms in patients with lung cancer, the incidence of lung cancer-related cough, the assessment of the proportion of central antitussive drugs, and the commonly used central antitussives. Results: Questionnaires from 2 424 medical providers were collected from 402 hospitals in 21 provincial administrative units. Cough was the most common symptom in lung cancer. Most physicians believed that the incidence of lung cancer-related cough was 51%~75%, while the proportion of patients satisfied with the treatment was only 11%~20%. The evaluation of lung cancer-related cough was seriously insufficient. The leading cause of lung cancer-related cough was tumors. And the main problem was the inadequate antitussive effect of drugs in lung cancer-related cough management. The proportion of central antitussive medication usage in the secondary and tertiary hospitals was 93.9% and 92.0%, significantly higher than 75.0% in Primary hospitals (χ²=8.390, P =0.015). The proportion of the physicians who underhanded that codeine is at risk of addiction was 76.6% and 72.0% in the secondary and tertiary hospitals, which were significantly higher than 53.9% in Primary hospitals (χ²=9.240, P =0.010). In different occupations, the proportions of doctors and pharmacists who knew the risk of addicting to codeine were 73.0% and 82.6%, which were significantly higher than the 66.4% of nurses (χ²=21.200, P< 0.001). The Chinese medical providers were lack of training about the basic knowledge of using central antitussive medication. Conclusions: The proportion of patients who were satisfied with the effect of cough treatment is low. The medical staff did not have enough awareness of this. There was an urgent need to develop a consensus and standardize lung cancer cough diagnosis and treatment in China.

- Abstract
Objective: To investigate the effects and the mechanism of FoxO6 on the proliferation and invasion of colorectal cancer cells. Methods: FoxO6 siRNA was transfected into colorectal cancer cell HCT116 and SW480. The overexpression vector pcDNA.3.1-c-Myc was constructed and co-transfected into HCT116 and SW480 cells with FoxO6 siRNA. Real-time fluorescent quantitative PCR (RT-qPCR) and western blot were used to detect the mRNA and protein expressions of FoxO6, c-Myc, and p21 in HCT116 and SW480 cells. Bromodeoxyuridine (BrdU) was used to detect cell proliferation and Transwell assay was performed to detect the invasion ability of these cells. SW480 cells transfected with FoxO6 shRNA lentivirus (LV-FoxO6) and were injected into the right armpit of BAL b/c nude mice to construct a tumor-bearing mode and the tumor volumes were measured on the days of 10, 13, 16, 19, 22, and 25 after injection. Results: The FoxO6 mRNA were 0.91±0.04, 1.72±0.07, and 2.03±0.06, and protein expression were 0.70±0.04, 1.35±0.08, and 1.56±0.07 in normal colon cell FHC, colorectal cancer cells HT116 and SW480, respectively. The protein and mRNA levels of FoxO6 in HCT116 and SW480 were significantly higher than those in FHC (both P <0.05). Knockdown of FoxO6 in HCT116 and SW480 cells decreased the mRNA and protein expressions of FoxO6 (both P <0.05), the cell proliferation ability (absorbances were 0.26±0.07 and 0.27±0.06, both P <0.05), cell invasion ability (the invaded cell numbers were 42.3±3.3 and 45.7±4.1, both P <0.05), and the mRNA and protein expressions of c-Myc, while increased the mRNA and protein expressions of p21 (both P <0.01). Overexpression of Myc in FoxO6 silenced HCT116 and SW480 cells decreased the expression of p21, while increased the cell proliferation ability (absorbances were 0.54±0.09 and 0.58±0.07, both P <0.01) and invasion ability (the invaded cell numbers were 79.2±5.9 and 80.5±6.4, both P <0.01). On the 25th day after cell inoculation in nude mice, the tumor volume of LV-FoxO6 group was (190.6±36.2) mm(3), significantly lower than (437.8.6±69.2) mm(3) of LV-NC group ( P <0.05). Conclusion: FoxO6 promotes the proliferation and invasion of colorectal cancer cells through facilitating c-Myc mediated p21 expression inhibition.

- Abstract
Objective: To observe the expressions of periostin (Postn) in colon cancer tissues and cells, and to investigate its biological effect and mechanism in colon cancer cells. Methods: Real-time quantitative polymerase chain reaction (RT-qPCR) and western blot were used to detect the expressions of Postn, let-7a and miR-98 in 20 pairs of colon cancer tissues and adjacent normal tissues, colon cancer cell lines including SW480, HT-29, HCT-116 and human normal colon epithelial cell NCM460. Small interfering RNAs (siRNAs) of Postn, pcDNA3.1-Postn plasmids, let-7a mimic and its negative control let-7a mimic-NC, miR-98 mimic and its negative control miR-98 mimic-NC were transfected into HCT-116 cells. 3-(4, 5-dimethyl-2-thiazolyl)-2, 5-diphenyl-2H tetrazolium bromide (MTT) was used to detect cell viability. Flow cytometry was used to detect cell apoptosis. Luciferase reporter gene assay was used to determine the targeting relationship between miRNAs and Postn. Results: Compared with adjacent normal tissues, Postn expression was up-regulated ( P <0.05) while let-7a/miR-98 expression was down-regulated ( P <0.05) in colon cancer tissues. Compared with NCM460 cells, Postn expression was up-regulated ( P <0.05) while let-7a/miR-98 expression was down-regulated ( P <0.05) in SW480, HT-29 and HCT-116 cells. In colon cancer tissues, the expression of Postn was negatively correlated with the expressions of let-7a and miR-98 ( r =-0.69, P <0.001; r =-0.80, P <0.001). Inhibition of Postn in vitro reduced the viability of HCT-116 cells [(53.73±7.63)%, P <0.05], increased the apoptotic rate [(22.88±3.40)%, P <0.05], enhanced the expression of epithelial-mesenchymal transition (EMT) marker E-cadherin (2.44±0.39, P <0.05), while down-regulated the expressions of N-cadherin and Vimentin (0.44±0.07 and 0.38±0.06, P <0.05). Overexpression of Postn in vitro enhanced the cell viability of HCT-116 cells [(134.41±8.82) %, P <0.05], decreased the expression of E-cadherin (0.55±0.09, P <0.05), increased the expressions of N-cadherin and Vimentin (2.93±0.42 and 2.24±0.34, P <0.05), but had no effect on the apoptotic rate ( P >0.05). Overexpression of let-7a or miR-98 partially reversed the biological effects of Postn overexpression in colon cancer cells, which implicated that Postn was a target gene of let-7a/miR-98. Conclusions: Postn is a cancer-promoting molecule of colon cancer, and inhibition of Postn expression can increase the apoptotic rate of colon cancer cells and repress EMT. Postn expression and function is regulated by let-7a/miR-98.

- Abstract
Objective: To investigate the expression of long non-coding RNA LINC00339 in colorectal cancer patients and its effect and mechanism on proliferation and apoptosis of colorectal cancer cells. Methods: A retrospective analysis of 158 pathology-confirmed colorectal cancer patients, who were enrolled from August 2015 to January 2017, was performed. LINC00339 expression in colorectal cancer tissues and adjacent colorectal sampleswas detected by Real-time PCR. The correlation between LINC00339 expression and clinicopathological features as well as the relationship between LINC00339 and microRNA (miR)-218 expression was assayed. The interaction between LINC00339 and miR-218 was further confirmed by dual luciferase report system. Downregulation of LINC00339 was performed by siRNA interference technology in LoVo and HCT116 cells. Real-time PCR was used to detect miR-218 expression. 3-(4,5-dimethyl-2-thiazolyl)-2, 5-diphenyl-2-H-tetrazolium bromide (MTT) analysis was carried out to examine cell viability. Flow cytometry was used to determine cell apoptosis. Additionally, LINC00339 siRNA and miR-218 antagomirs (anti-miR-218) were co-transfected into LoVo and HCT116 cells, and then cell viability and apoptosis were detected. Results: LINC00339 expression was significantly increased in colorectal cancer tissues compared with adjacent colorectal tissues (4.69±1.52 vs 1.02±0.38, P< 0.05). LINC00339 expression was not related to the age and gender of patients ( P> 0.05), but was associated with TNM stage, lymphatic metastasis, tumor maximum diameters, and differentiation degree (all P< 0.05). LINC00339 expression was negatively correlated with miR-218 expression in colorectal cancer tissues ( P< 0.05). miR-218 mimics remarkably suppressed the fluorescence intensity of wild-type LINC00339 plasmid ( P= 0.001), but did not affect the fluorescence intensity of the mutant ones( P= 0.88). Knockdown of LINC00339 remarkably inhibited proliferation, but promoted apoptosis of LoVo and HCT116 cells (all P< 0.05). Compared with cells transfected with LINC00339 siRNA only, downregulation of miR-218 elevated proliferation and decreased apoptosis of LoVoand HCT116 cells. Conclusions: LINC00339 expression is upregulated in colorectal cancer tissues and correlated with patients' clinicopathological features. LINC00339 promotes proliferation, and suppresses apoptosis of colorectal cancer cells via downregulating miR-218.

- Abstract
Objective: To investigate the role of microRNA-96-5p in the proliferation and invasion of gastric cancer cells and its molecular mechanism. Methods: From June 2015 to January 2017, 53 resected specimens were collected. The transcriptional levels of microRNA-96-5p and forkhead box Q1 (FoxQ1) in gastric cancer tissues and the matched para-cancerous tissues were quantified by quantitative real-time PCR (qRT-PCR). The expression of FoxQ1 protein was also detected by immunohistochemistry (IHC). The relationship between microRNA-96-5p expression and the clinicopathological features of gastric cancer and its correlation with FoxQ1 expression were analyzed. The expressions of miRNA-96-5p in gastric cancer tissue and adjacent normal tissue were detected by qRT-PCR. miRNA-96-5p mimics was transfected to BGC-823 gastric cancer cells. The effects of miRNA-96-5p on cell proliferation and invasion were detected by cell counting kit-8 (CCK-8) assay and Transwell assay, respectively. The protein expressions of FoxQ1, E-cadherin and vimentin were determined by western blot. The relationship between FoxQ1 and miRNA-96-5p expressed in BGC-823 cells was detected by dual-luciferase reporter assay. Results: The median expression of miRNA-96-5p in gastric cancer tissue was 1.05, significantly lower than 3.23 of para-cancerous tissues ( P <0.05). The positive rate of FoxQ1 expression in gastric cancer tissue was 71.7%, significantly higher than 28.3% of para-cancerous tissues ( P <0.05). The expression of FoxQ1 was negatively corelated with the level of miRNA-96-5p ( r =-0.613, P =0.006). The expression of miRNA-96-5p in gastric cancer cell BGC-823 was significantly decreased compared with normal gastric epithelial cell (0.96±0.08 vs 2.84±0.15, P <0.05). The results of CCK-8 assay and Transwell assay showed that overexpression of miRNA-96-5p significantly reduced the proliferation and invasion abilities of gastric cancer cells ( P <0.05). Overexpression of miRNA-96-5p decreased the protein level of FoxQ1. Moreover, it upregulated the expression of E-cadherin and downregulated the expression of vimentin. The result of dual-luciferase-3'-UTR reporter assay confirmed that miRNA-96-5p binds to the 3'UTR of FoxQ1. Conclusion: miRNA-96-5p may suppress the proliferation, migration and epithelial-mesenchymal transition (EMT) of gastric cancer cell by down-regulation of FoxQ1.

- Abstract
Objective: To explore the roll and function of hydroxymethylglutaryl-CoA synthase 2 (HMGCS2) in the development and progression of human esophageal squamous cell carcimoma(ESCC). Method: Using immunohistochemistry, the expression of HMGCS2 was determined in 150 primary ESCC patients from July 2002 to December 2005 in the People's Hospital of Linzhou City, Henan Province. And HMGCS2 over-expression ESCC cell lines were established to verify HMGCS2 gene function. Result: In 150 cases of ESCCs, the expression rate of HMGCS2 was 58% (87/150), which was lower than 72% (108/150) in paired normal tissues, the difference was statistically significant ( P =0.013). HMGCS2 down-regulated expression was associated with tumor cell differentiation ( P =0.022), pT status ( P =0.036), pN status ( P =0.017) and TNM stage( P =0.012). The 5-years disease-specific survival (DSS) in down HMGCS2 expression group (14 months) was poorer than those in normal expression group (20 months; P =0.002). In addition, multivariate Cox regression analysis showed that HMGCS2 expression ( Wald =7.136, P =0.008) was an independent risk factor for DSS. Furthermore, functional studies demonstrated that HMGCS2 gene could suppress the tumorigenic ability of ESCC cells (OD: 0.79±0.04 vs 1.25±0.68; P =0.01), the formation of colone (number of colones: 30±10 vs 189±15, P =0.002), and cell motility (number of cells: 27±14 vs 222±40, P =0.009). Conclusion: HMGCS2 can inhibit the proliferation and migration of ESCC cells, and could be an important candidate tumor suppressor gene for ESCC.

- Abstract
Objective: To explore the clinical characteristics, surgical procedures and prognosis of solid pseudopapillary tumor of the pancreas(SPTP). Methods: The clinical and follow-up data of 55 cases with SPTP in Henan Tumor Hospital from June 2005 to April 2015 were retrospectively analyzed. Results: There were 55 SPTP cases, including 7 males and 48 females. The age ranged from 16 to 76 (median, 33). Clinical presentations of SPTP were not specific. The mean size of the tumor was 7.6 cm (range from 2 to 25cm). Pancreatic head and tail were the most common locations of SPTP. All the patients received surgical resection with a definitive pathological diagnosis. Some immunohistochemical markers were mostly positive, including β-catenin, Vim, Syn, CD10, CD56, PR, etc. With a median follow-up of 53 months, the 1-year, 2-year and 5-year survival rate were 98.1%, 96.1% and 94.0%, respectively. Conclusions: SPTP is an uncommon exocrine pancreatic neoplasm with low malignant potential, which frequently occurs in young women. Preoperative imaging can provide evidence for the selection of treatment modalities among which surgical resection ispreferred. Diagnosis still relies on pathology and immunohistochemistry.

- Abstract
Objective: To observe bevacizumab plus chemotherapy curative effect and safety for recurrent and metastatic cervical cancer., Materials and Methods: Retrospective analysis of 30 recurrent and metastatic cervical cancer cases. The experimental group received beva- cizumab plus paclitaxel-, docetaxel-, and platinum-based chemotherapy. The control group received only chemotherapy. Curative effects were recorded after at least two treatment cycles; adverse reactions were recorded with every cycle., Results: Experimental group patients were treated for an average 2.6 cycles. Compared to the control group, the experimental group effective rate (26.7%) was similar, disease control rate (73.7%) was significantly higher, and median survival time was three months longer. Bevacizumab-associated adverse reactions were bleeding, hypertension, and thrombosis/embolism; most were level 1 and 2 reactions. Adverse reactions in the two groups were not statistically different., Conclusions: The bevacizumab plus chemotherapy disease control rate for recurrent and metastatic cervical cancer is comparatively high, prolonging median survival; bevacizumab-associated adverse reactions are mild and tolerable.

- Abstract
Objective: To investigate the number of metastatic lymph nodes (pN) and the metastatic lymph node ratio (LNR) on the post-surgical prognosis of patients with esophageal cancer (EC). Methods: A retrospective analysis of 573 inpatients diagnosed as esophageal carcinomas from March 2008 to June 2012 was carried out.All pathologic specimen were reviewed by pathologists from Henan Tumor Hospital.The Kaplan-Meier method was used to calculate survival rates, and survival curves were compared with the Log-rank test.The Cox model was employed for multivariate analyses of factors.The association of pN and LNR with prognosis of esophageal cancer was examined by the area under the ROC curve(AUC). Results: The 1-, 3- and 5-year OS rates were 72.5%, 46.1% and 32.3%, respectively.Univariate analysis showed that tumor location( P =0.020), tumor length( P =0.009), pT stage( P =0.011), pN stage( P <0.01), and the LNR( P <0.01) were prognostic factors for OS.Multivariate analysis indicated that pT stage( P =0.047), pN stage( P =0.018) and LNR( P =0.011) were significant and independent risk factors for poor OS.ROC analysis indicated that LNR (AUC=0.680) had better predictive value than pN (AUC=0.579). Conclusion: The integrated use of LNR and pN may be suitable for evaluation of prognosis in patients with EC and positive nodal metastasis after curative resection.
