Abstract
In this study,90Sr was used as the test radionuclide to characterize the sorption kinetics and effects of initial 90Sr activity and remaining 90Sr in solid concentration were simulated for a near-surface repository. The study focused on the sorption characteristics of radionuclides in unsaturated groundwater environment (or vadose zone) is the important information for investigating the near-surface disposal of intermediate and low-level radioactive waste (ILLW). Moreover, the 90Sr sorption experiments reached equilibrium within 56 h, which fit to the first order sorption kinetic model, and the remaining 90Sr in mudrock samples showed obvious sorption equilibrium hysteresis, which fit to the second order sorption kinetic model. Before reaching the maximum sorption capacity, the sorption rate constant increases with 90Sr increasing; the distribution coefficient (Kd) of 56 h decreases with the remaining 90Sr decreasing. In addition, it showed that the slow sorption process dominated before the sorption reaches equilibrium. In fact, a reliable safety assessment methodology for on-going near-surface repository required a lot of the radionuclides parameters with local environment including the radionuclides sorption/desorption rate constant and maximum sorption capacity.

Abstract
Objective: To explore the debulking strategy of lower extremity artery lesions. Methods: Retrospectively analyzed the clinical data of 101 patients underwent debulking therapy at Department of Vascular Surgery,Zhongshan Hospital,Fudan University from June 2019 to June 2020.There were 74 males and 27 females,aged (73.2±11.7)years (range:35 to 93 years).There were 31 cases in Rutherford class 3,39 cases in class 4 and 31 cases in class 5. Hypertension occurred in 72 patients. One hundred and forty lesions were treated in 101 patients. Among them, there were 13 lesions(9.3%) in iliac artery,72 lesions(51.4%) in superficial femoral artery,41 (29.3%) lesions in popliteal artery,10 lesions(7.1%) in tibiofibular trunk,and 4 lesions(2.9%) in below the knee artery.Percutaneous mechanical thrombectomy (PMT) was mainly used in acute thrombosis,excimer laser ablation (ELA) was mainly used for chronic in-stent restenosis and chronic stenosis or totally occlusive lesions,while directional atherectomy (DA) was mainly used for short calcified lesions. Results: All of the patients underwent debulking therapy. Eighty-two lesions(58.6%,82/140) were treated by PMT, 56 (40.0%,56/140) were treated by ELA,and 2 (1.4%,2/140) were treated by DA.The ankle-brachial index of the patient was 0.44±0.19 before surgery, 0.87±0.17 immediately after surgery (t=-16.26, P<0.01), and 0.81±0.20 at 6 months after surgery(t=-14.67,P<0.01),and 0.79±0.15 (t=-14.12,P<0.01) at 12 months after surgery. At 12 months,the primary patency was 86.1% (87/101),mortality was 5.0% (5/101), freedom from major-amputation survival rate was 93.1% (94/101),and target lesion reintervention rate was 9.9% (10/101). Conclusions: Debulking is feasible and effective to eliminate the arterial contents and maximize the acquisition of lumen.Selection of suitable debulking methods for different segments and lesions would be helpful to improve the technical success and obtain satisfactory results.

Abstract
Hypoxia is a prominent feature of head and neck cancer. However, the oxygen element characteristics of proteins and how they adapt to hypoxia microenvironments of head and neck cancer are still unknown. Human genome sequences and proteins expressed data of head and neck cancer were retrieved from pathology atlas of Human Protein Atlas project. Then compared the oxygen and carbon element contents between proteomes of head and neck cancer and normal oral mucosa-squamous epithelial cells, genome locations, pathways, and functional dissection associated with head and neck cancer were also studied. A total of 902 differentially expressed proteins were observed where the average oxygen content is higher than that of the lowly expressed proteins in head and neck cancer proteins. Further, the average oxygen content of the up regulated proteins was 2.54% higher than other. None of their coding genes were distributed on the Y chromosome. The up regulated proteins were enriched in endocytosis, apoptosis and regulation of actin cytoskeleton. The increased oxygen contents of the highly expressed and the up regulated proteins might be caused by frequent activity of cytoskeleton and adapted to the rapid growth and fast division of the head and neck cancer cells. The oxygen usage bias and key proteins may help us to understand the mechanisms behind head and neck cancer in targeted therapy, which lays a foundation for the application of stoichioproteomics in targeted therapy and provides promise for potential treatments for head and neck cancer.

Abstract
OBJECTIVE To evaluate the impact of water pollutants, water levels and meteorological factors on the Oncomelania hupensis density in Eastern Dongting Lake regions, so as to provide insights into schistosomiasis control. METHODS O. hupensis snails were surveyed using a systematic sampling method in snail-infested marshlands in Eastern Dongting Lake regions from 2007 to 2014, and data pertaining to water pollutants, water levels and meteorological factors were collected. The duration of submergence and the date of the start of submergence were calculated. The snail density and its influencing factors were descriptively analyzed, and a linear mixed model was generated to examine the impacts of variables on the snail density. In addition, smooth curves were fitted to investigate the relationship between snail density and variables. RESULTS The snail density appeared a fluctuation in Eastern Dongting Lake regions during the period from 2007 to 2014, with the highest density on October, 2010 (52.79 snails/0.1 m2) and the lowest density on January 2009 (2.15 snails/0.1 m2). Linear mixed-model analysis showed that permanganate index, total phosphorus and the date of the start of submergence affected the snail density (t = 6.386, -2.920 and -3.892, all P values < 0.01). Smooth curve analysis revealed that the associations of the snail density with the permanganate index and total phosphorus appeared an approximately quadratic curve. After the end of April, the earlier date of the start of submergence resulted in a higher snail density. CONCLUSIONS Permenganate index, total phosphorus and the date of the start of submergence affect the O. hupensis snail density in Eastern Dongting Lake regions.

Abstract
Abstract
Buffer/backfill materials for radioactive waste disposal sites consist of pure bentonite or bentonite-rock mixtures. In this study, the batch test method was used to obtain the sorption characteristics of important radionuclides such as Cs, Sr and Co on buffer/backfill materials; i. e., mixing Wyoming MX-80 bentonite or local Taiwanese Zhi-Shin bentonite with possible host rock (argillite and granite) in different proportions (0∼100%). The distribution coefficients (Kd) for Cs, Sr and Co were obtained from the experiments. The distribution coefficient for the bentonite-rock mixtures were found, with more than 50% of mixing proportion of bentonite to argillite or granite, to have very similar values to that of pure bentonite. Furthermore, it was clearly found that the sorption of Cs, Sr and Co to bentonite-rock mixtures is decreased as ionic strength of the liquid phase is increased from 0.001M to 1M for NaCl solutions. According to the experimental results, in synthetic groundwater, it is quite convenient and helpful to assess the distribution coefficients (Kd) of Cs, Sr and Co for buffer/backfill materials using batch sorption experiments with bentonite-rock mixtures of fixed mixing proportions.

Abstract
Rainfall use efficiency (RUE) is crucial for understanding the changes in grassland productivity due to variations in future rainfall patterns. Recently, numerous studies have been conducted on the relationship between RUE and the amount of rainfall, but there has been little research on the influence of rainfall distribution and the interactive effect of rainfall amounts and distribution on RUE. Here, a simulated rainfall experiment was conducted to evaluate the impacts of rainfall amount (average rainfall amount (R0), 334 mm; decreased (R-) and increased (R+) rainfall amounts, 233 mm and 434 mm, respectively) and dry intervals (comprising 6-day, 9-day, 12-day, 15-day, 18-day and 21-day intervals between rainfall) on productivity and RUE in Leymus chinensis (Trin.) Tzvel., a dominant grass of the Eastern Eurasian Steppe. Our results showed that (1) for biomass production and RUE, moderate extension of dry intervals was conducive to enhancing total biomass production and RUE. The peak values of total biomass and RUE appeared during the 15-day interval for R-, and the 18-day interval for R0 and R+. (2) For biomass allocation, extension of dry intervals decreased the stem to leaf ratio (S/L) and the root to shoot ratio (R/S). (3) Further, the S/L ratio was significantly negatively correlated with RUE. These results suggest that variations in rainfall patterns can alter the RUE by changing the S/L ratio, and finally influence biomass production in L. chinensis. These findings have important implications for understanding and predicting the effect of future climate change on productivity in semi-arid grassland.

Abstract
UNLABELLED China is a middle-risk country for hip fracture at present, which differs from previous data that it was low-risk. By 2050, the total number of hip fractures in people older than 65 years is predicted to be 1.3 million. INTRODUCTION To assess hip fracture incidence in China and examine the heterogeneity of hip fracture in seven geographical regions of China. METHODS There were 238,230 hip fracture patients aged 65 years or older from 2013 to 2016 from a large national in-patients database (HQMS) involving 30.6 million hospitalizations. Taking into account the total national hospitalization rate per calendar year, we estimated the incidence of hip fracture per 100,000 residents older than 65 years in China overall and in seven geographical Chinese regions. RESULTS The proportion of men and women older than 65 years with hip fractures was 1.00:1.95. Between 2013 and 2016, the number of hip fractures per 100,000 people age 65+ was 278. China has vast territories; the number of hip fractures per 100,000 people over 65 years old was 202 in Northeast China and 374 in Northwest China. Northwest has higher altitude, lower population density, is less developed with lower urbanization than Northeast China which is low altitude, and highly urbanized. CONCLUSIONS China should no longer be regarded as a low-risk country for hip fracture. By 2050, the total number of hip fractures in people older than 65 years in China is predicted to be 1.3 million. Higher altitude areas had higher hip fracture rates than lower altitude, higher urbanized areas.

Abstract
We report on the first measurement of charm-strange meson D_{s}^{±} production at midrapidity in Au+Au collisions at sqrt[s_{NN}]=200 GeV from the STAR experiment. The yield ratio between strange (D_{s}^{±}) and nonstrange (D^{0}) open-charm mesons is presented and compared to model calculations. A significant enhancement, relative to a pythia simulation of p+p collisions, is observed in the D_{s}^{±}/D^{0} yield ratio in Au+Au collisions over a large range of collision centralities. Model calculations incorporating abundant strange-quark production in the quark-gluon plasma and coalescence hadronization qualitatively reproduce the data. The transverse-momentum integrated yield ratio of D_{s}^{±}/D^{0} at midrapidity is consistent with a prediction from a statistical hadronization model with the parameters constrained by the yields of light and strange hadrons measured at the same collision energy. These results suggest that the coalescence of charm quarks with strange quarks in the quark-gluon plasma plays an important role in D_{s}^{±}-meson production in heavy-ion collisions.

Abstract
Objective To establish a detection method for common new psychoactive substances of synthetic cannabinoids in hair with ultra-high performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS). Methods In the 1 mL of internal standard methanol solution, 20 mg hair was added. After cryogenic grinding and ultrasonic extraction, the extract was separated by ACQUITY UPLC HSS T3 column (100 mm×2.1 mm, 1.8 μm). The mobile phase A was aqueous solution that composed of 20 mmol/L ammonium acetate, 0.1% formic acid, and 5% acetonitrile. The mobile phase B was acetonitrile. Electrospray ionization source in positive ion mode was used for data acquisition in multi-reaction monitoring (MRM) mode. Results The seven common new psychoactive substances of synthetic cannabinoids in hair had a good linear relationship within their respective linear ranges (r>0.99), the limits of detection were 0.5-2 pg/mg, the limits of quantification were 1-5 pg/mg, the intra-day and inter-day precisions were 0.1%-12.6%, the intra-day and inter-day accuracies were 89.2%-110.7%, the recovery rates were 52.3%-93.3%, and the matrix effects were 19.1%-95.2%. Conclusion The established method has a simple sample preparation process and high sensitivity. It is suitable for qualitative and quantitative analysis of common new psychoactive substances of synthetic cannabinoids in hair.

Romosozumab efficacy on fracture outcomes is greater in patients at high baseline fracture risk: a post hoc analysis of the first year of the frame study. Osteoporos Int 2021; 32:1601-1608.

Abstract
UNLABELLED This study aimed to determine the interaction between baseline FRAX® fracture probability and romosozumab efficacy. Using an ITT approach, it was determined that the efficacy of romosozumab on clinical fracture, osteoporotic fracture, and major osteoporotic fracture is significantly greater in patients at high baseline fracture risk, when compared with placebo. INTRODUCTION Post hoc analyses of placebo-controlled osteoporosis treatment studies have shown significantly greater reductions of fracture incidence for higher fracture risk patients. This study determined the interaction between baseline FRAX® fracture probability and romosozumab efficacy in the placebo-controlled first year of the phase 3 FRAME study (NCT01575834). METHODS Using an ITT approach, an extension of Poisson regression analysis studied the relationship between treatment, FRAX® 10-year probability of major osteoporotic fracture (MOF, calculated without BMD) and risk of first incident fracture (adjusting for age and follow-up time). Treatment interactions considered outcomes of all clinical fractures, osteoporotic fractures, MOF, clinical vertebral fractures, and morphometric vertebral fractures. Two-sided p value of < 0.1 for the interaction between treatment and FRAX® was considered significant. RESULTS Compared with placebo, romosozumab reduced the incidence of all fracture outcomes in the first year (range: 32% reduction in MOF [p = 0.07] to 80% reduction in clinical vertebral fractures [p = 0.038]). Significant interactions were observed between efficacy and baseline FRAX® probability for composite outcomes of clinical fractures, osteoporotic fractures, and MOF (p = 0.064-0.084), but not vertebral fractures (p > 0.3). For example, romosozumab decreased all clinical fractures by 22% at the 25th centile of FRAX® probability but the reduction was 41% at the 75th centile. Exclusion of vertebral fractures from each composite fracture outcome (i.e. only nonvertebral fractures included) showed even stronger interactions with baseline FRAX® probability (p = 0.036-0.046). CONCLUSIONS Efficacy of romosozumab on clinical fracture, osteoporotic fracture, and MOF is significantly greater in patients at high baseline fracture risk compared with placebo.

Abstract
Objective: To investigate the incidence of anemia and risk factors in HIV/AIDS patients with access to antiretroviral therapy (ART) during 2004-2018 in Dehong Jingpo and Dai Autonomous Prefecture (Dehong). Methods: A retrospective cohort study was conducted in HIV/AIDS patients receiving ART in Dehong during 2004-2018 based on the data extracted from the National HIV/AIDS antiretroviral therapy database. Cox proportional risk model was used to analyze the factors associated with the incidences of anemia and moderate or severe anemia in the HIV/AIDS patients. And the piecewise linear mixed-effects model was used to depict the trajectory of hemoglobin changes over time after initiating ART according to baseline level. Results: A total of 8 044 HIV/AIDS patients were included, in whom 6 337 (78.8%) were without anemia at baseline survey and had a median follow up time of 4.43 (P25, P75: 1.50, 6.71) years. The median follow up time for 1 291 new anemia cases and 293 new moderate or severe anemia cases was 0.16 (P25, P75: 0.07, 1.99) years and 0.48 (P25, P75:0.09, 2.97) years, respectively. The incidence rate of anemia and moderate or severe anemia was 4.40 per 100 person-years and 0.41 per 100 person-years respectively. In multivariable Cox regression analysis, older age, being female, being in Dai and Jingpo ethnic group, baseline BMI <18.5 kg/m2, baseline CD4+T lymphocyte cell counts (CD4) <200 cells/μl, and zidovudine (AZT) -based initial treatment regimen were factors significantly and positively associated with incidence of anemia after treatment. Factors as being female, being in Dai ethnic group, baseline BMI <18.5 kg/m2, mild baseline anemia, and AZT-based initial treatment regimen were significantly and positively associated with incidence of moderate or severe anemia after treatment. Conclusion: The risk for anemia was higher in HIV/AIDS patients with specific characteristics, such as age ≥60 years , being female, being in Dai and Jingpo ethnic groups, lower BMI, CD4 <200 cells/μl, and treatment of AZT, after initiation of ART in Dehong during 2004-2018. Additional efforts are needed to strengthen the screening, prevention and treatment of anemia in this population.

Abstract
BACKGROUND Ameloblastoma is the most frequent odontogenic tumor. Various evidence has highlighted the role of somatic mutations, including recurrent mutation BRAF V600E, in the tumorigenesis of Ameloblastoma, but the intact genetic pathology remains unknown. MATERIAL AND METHODS We sequenced the whole exome of both tumor tissue and healthy bone tissue from four mandibular ameloblastoma patients. The identified somatic mutations were integrated into Weighted Gene Co-expression Network Analysis on publicly available expression data of odontoblast, ameloblast, and Ameloblastoma. RESULTS We identified a total of 70 rare and severe somatic mutations. We found BRAF V600E on all four patients, supporting previous discovery. HSAP4 was also hit by two missense mutations on two different patients. By applying Weighted Gene Co-expression Network Analysis on expression data of odontoblast, ameloblast, and Ameloblastoma, we found a proliferation-associated gene module that was significantly disrupted in tumor tissues. Each patient carried at least two rare, severe somatic mutations affecting genes within this module, including HSPA4, GNAS, CLTC, NES, and KMT2D. All these mutations had a ratio of variant-support reads lower than BRAF V600E, indicating that they occurred later than BRAF V600E. CONCLUSIONS We suggest that a severe somatic mutation on the gene network of cell proliferation other than BRAF V600E, namely second hit, may contribute to the tumorigenesis of Ameloblastoma.

Abstract
Objective: To explore the prognostic factors of patients with advanced epithelial ovarian cancer (EOC) who received neoadjuvant chemotherapy (NACT) followed by interval debulking surgery (IDS). Methods: The clinical and pathological data of patients with stage Ⅲc-Ⅳ EOC underwent surgical treatment in Sichuan Cancer Center from January 1st, 2014 to December 31th, 2018 were retrospectively analyzed, and the prognosis was followed up. Results: (1) A total of 216 EOC patients were included in the study, whose age was (52.1±8.7) years old, the median follow-up time was 44.6 months (17.2-80.1 months), the median progression free survival (PFS) was 11.1 months (8.5-13.8 months), and the median overall survival (OS) was 40.0 months (32.7-47.3 months). (2) Among 216 patients with advanced EOC, there were 75 cases in the primary debulking surgery (PDS) group and 141 cases in the NACT+IDS group. Compared with the PDS group, the serum CA125 level before treatment (median: 859.4 vs 1 371.0 kU/L), proportion of stage Ⅳ patients [5.3% (4/75) vs 23.4% (33/144)] and no visible residual disease (R0) cytoreduction rate in the NACT+IDS group were significantly higher [(41.3% (31/75) vs 61.7% (87/144); all P<0.05]. The median PFS in the NACT+IDS group was significantly shorter than that of the PDS group (9.1 vs 15.2 months; χ2=7.014, P=0.008), but there was no significant difference in the median OS between the two groups (42.6 vs 38.0 months; χ2=1.325, P=0.250). (3) Univariate analysis showed that body mass index (BMI), preoperative serum CA125 level, surgical-pathological stage, NACT effect, postoperative residual tumor size, time to initiation of postoperative chemotherapy and chemotherapy regimen were significantly correlated with PFS in the NACT+IDS group (all P<0.05); preoperative serum CA125 level, surgical-pathological stage, NACT effect, postoperative residual tumor size, postoperative chemotherapy regimen were significantly related with OS in the NACT+IDS group (all P<0.05). Multivariate analysis showed that BMI, postoperative residual tumor size, time to initiation of postoperative chemotherapy were independent factors of PFS in the NACT+IDS group (all P<0.05); preoperative serum CA125 level, surgical-pathological stage, postoperative residual tumor size were independent factors of OS in the NACT+IDS group (all P<0.05). The results showed that the PFS of patients with normal preoperative serum CA125 level and (or) chemotherapy ≤7 days after IDS was longer, while no significant difference comparable with those in the PDS group (P>0.05), and OS was also showing an prolonged trend, but the difference was also not statistically significant (P>0.05). Conclusions: Normal CA125 before IDS and time received chemotherapy no longer than 7 days after IDS are two related factors of prognosis benefit in advance EOC patients treated with NACT+IDS. Therefore, timely adjustment of the dose and regimen of NACT to reduce CA125 level to normal range in about three cycles before IDS, and strengthen IDS perioperative management to promote postoperative recovery and perform chemotherapy as soon as possible might help to improve the prognosis of patients.

Abstract
Abstract Objective To assess the feasibility of the rbcL sequence of chloroplast DNA as a genetic marker to identify Cannabis sativa L. Methods The rbcL sequences in 62 Cannabis sativa L. samples, 10 Humulus lupulus samples and 10 Humulus scandens DNA samples were detected, and 96 rbcL sequences of the Cannabaceae family were downloaded from Genbank. Sequence alignment was performed by MEGA X software, the intraspecific and interspecific Kimura-2-Parameter (K2P) genetic distances were calculated, and the system clustering tree was constructed. Results The rbcL sequence length acquired by sequencing of Cannabis sativa L. and Humulus scandens were 617 bp and 649 bp, respectively, and two haplotypes of Cannabis sativa L. were observed in the samples. The BLAST similarity search results showed that the highest similarity between the sequences acquired by sequencing and Cannabis sativa L. rbcL sequences available from Genbank was 100%. The genetic distance analysis showed that the maximum intraspecific genetic distance (0.004 9) of Cannabis sativa L. was less than the minimum interspecific genetic distance (0.012 9). The results of median-joining network and system clustering tree analysis showed that Cannabis sativa L. and other members of the Cannabaceae family were located in different branches. Conclusion The rbcL sequence could be used as a DNA barcode for identifying Cannabis sativa L., and combined with comparative analysis of the rbcL sequence and system cluster analysis could be a reliable and effective detection method for Cannabis sativa L. identification in forensic investigation.

Abstract
Objective: To explore the imaging features and clinical effect of accordion maneuver in promoting the bone healing at the docking site after tibial transport under ultrasonic monitoring. Methods: Retrospective analysis was conducted on the clinical data of 16 patients with tibial bone transport who were admitted to the Department of Orthopedics, the second Hospital of Shanxi Medical University from May 2018 to October 2019. All the patients were treated with accordion maneuver to promote bone healing at the docking site under ultrasound monitoring. There were 14 males and 2 females, aged (45.3±14.3) years (range: 6 to 61 years). Before tibial bone transport, the length of the tibial defect of 16 patients was (6.0±2.6) cm (range: 2.0 to 12.1 cm). The operation steps of accordion maneuver were as follows: pressurization for 2 weeks, suspension for 12 days, distraction for 2 weeks, retraction for 2 weeks, and then stop the operation to consolidate the bone mineralization. During accordion treatment, ultrasound was used to monitor the size of hematoma, Adler grade of blood flow signal and the changes of new callus in and around the docking site. X-ray was performed to monitor bone healing at the docking site. Pearson correlation coefficient was used to analyze the correlation between the size of hematoma, the resistance index of blood flow signal and the bone healing time of the docking site. Paley healing criterion was used to evaluate the bone healing and functional recovery of the patients. Results: During accordion maneuver, ultrasound examination showed that the Adler grade of blood flow signals around the docking site increased gradually before retraction and then decreased gradually, but the degree of callus mineralization continued to increase gradually. After 2 weeks of pressure on the docking site, hematoma was observed in 14 patients by ultrasound examination. X-ray showed that all docking sites had bony healing, with the healing time of (30.8±4.9) weeks (range: 23 to 40 weeks).The size of the hematoma was negatively correlated with the healing time of the docking site (r=-0.819,P<0.01). No hematoma was found in 2 patients, and after continuous observation for 20 weeks, there was still no obvious callus connection at the docking site. After bone cortical removal, ultrasound examination showed hematoma formed at the docking site. Accordion maneuver was continued, and the docking site healed at 30 and 32 weeks after surgery, respectively. There was a negative linear correlation between hematoma size at 2 weeks of compression and the blood flow resistance index at 2 weeks of retraction in 16 patients (r=-0.801, P<0.01). The patients were followed-up for (14.5±3.2) months (range: 10.6 to 20.2 months). At the last follow-up, 12 patients were evaluated as excellent and 4 were evaluated as good by Paley healing criteria. Conclusion: The distraction and compression stress applied in accordion maneuver can promote bone healing at the docking site, and ultrasound can monitor early signs of bone healing at the docking site to help determine the tendency of bone healing.

Abstract
OBJECTIVE The aim of this work was to investigate the mechanism by which long non-coding RNA (lncRNA) WTAPP1 promotes the malignant progression of laryngeal cancer. PATIENTS AND METHODS In this study, quantitative real-time polymerase chain reaction (qRT-PCR) examined the expression of lncRNA WTAPP1 in 49 pairs of tumor tissue specimens and paracancerous normal ones collected from laryngeal cancer patients. Subsequently, in the laryngeal squamous cell carcinoma cell lines AMC-HN-8 and Hep-2, WTAPP1 overexpression and knockdown vectors were constructed using lentivirus, and cell counting kit-8 (CCK-8), cell colony formation and 5-ethynyl-2'-deoxyuridine (EdU) assays were carried out to analyze the impact of lncRNA WTAPP1 on the function of laryngeal cancer cells. Finally, Luciferase reporting assay and recovery experiments were carried out to further explore whether lncRNA WTAPP1 has an impact on the malignant progression of laryngeal cancer via modulating microRNA-592. RESULTS QRT-PCR results revealed a significantly higher expression of lncRNA WTAPP1 in tumor tissues of patients with laryngeal cancer than that in adjacent normal ones. Compared with patients with low expression of WTAPP1, those with higher expression had a more advanced pathological stage. Meanwhile, the proliferation ability of cells in sh-WTAPP1 group was remarkably attenuated when compared with that in sh-NC group. In addition, microRNA-592 and WTAPP1 mRNA levels were found negatively correlated in laryngeal carcinoma tissue specimens. Luciferase reporter gene assay indicated that WTAPP1 can be targeted by microRNA-592 through certain binding sites. Moreover, we demonstrated through some recovery experiments that WTAPP1 can indeed serve as an oncogene accelerating the malignant progression of laryngeal cancer through the modulation of microRNA-592. CONCLUSIONS LncRNA WTAPP was markedly highly expressed both in laryngeal carcinoma tissues and cell lines, which was also found to be closely relevant to the pathological stage of laryngeal cancer patients. Additionally, lncRNA WTAPP1 is able to enhance the proliferation capacity of laryngeal carcinoma cells via regulating microRNA-592.

Abstract
Global polarization of Ξ and Ω hyperons has been measured for the first time in Au+Au collisions at sqrt[s_{NN}]=200 GeV. The measurements of the Ξ^{-} and Ξ[over ¯]^{+} hyperon polarization have been performed by two independent methods, via analysis of the angular distribution of the daughter particles in the parity violating weak decay Ξ→Λ+π, as well as by measuring the polarization of the daughter Λ hyperon, polarized via polarization transfer from its parent. The polarization, obtained by combining the results from the two methods and averaged over Ξ^{-} and Ξ[over ¯]^{+}, is measured to be ⟨P_{Ξ}⟩=0.47±0.10(stat)±0.23(syst)% for the collision centrality 20%-80%. The ⟨P_{Ξ}⟩ is found to be slightly larger than the inclusive Λ polarization and in reasonable agreement with a multiphase transport model. The ⟨P_{Ξ}⟩ is found to follow the centrality dependence of the vorticity predicted in the model, increasing toward more peripheral collisions. The global polarization of Ω, ⟨P_{Ω}⟩=1.11±0.87(stat)±1.97(syst)% was obtained by measuring the polarization of daughter Λ in the decay Ω→Λ+K, assuming the polarization transfer factor C_{ΩΛ}=1.

Abstract
Objective: To evaluate the results of excimer laser ablation (ELA) in the treatment of lower limb atherosclerotic obliterans (ASO). Methods: From June 2019 to March 2020, patients who underwent ELA combined with drug-coated balloon (DCB) for lower limb atherosclerotic obliterans (ASO) were enrolled. Demographics, lesion characteristics, procedure-related outcomes and complications were collected and analyzed. Results: Thirty patients were enrolled, including 21 males and 9 females. The mean age was (76.5±10.5) years. The mean lesion length was (11.7±6.4) cm. A total of 41 lesions, including in-stent restenosis (ISR) in 12 (29.3%), chronic totally occlusion (CTO) at initial treatment in 24 (58.5%), and severe stenosis in 5 (12.2%) patients. Sixteen (51.6%) patients were classified as Peripheral Arterial Calcium Scoring System (PACSS) category 4. The technical success rate was 93.5%. Incidence of distal embolization and bailout stenting was 12.9% and 6.5%, respectively. The mean follow-up time was (6.6±3.0) months. Ankle-brachial index (ABI) was significantly increased from 0.43(0.32,0.55) preoperatively to 0.91(0.87,1.01) postoperatively (Z=-5.43, P<0.01) and 0.82(0.73,1.02) (Z=-3.99, P<0.01) three months after surgery. The 3-month major-amputation free survival rate was 96.7%, primary patency rate was 100%, the target lesion reintervention (TLR) rate was 0 and ulcer healing rate was 76.9%. Conclusion: Debulking of ELA is feasible and effective for both ISR and CTO at initial treatment, providing a new option for DCB preparation and reducing stent implantation.

Venous superdrainage using superficial circumflex iliac vein in deep circumflex iliac artery perforator flap with iliac crest for oromandibular reconstruction. Int J Oral Maxillofac Surg 2021; 51:38-43.

Abstract
The deep circumflex iliac artery perforator flap with iliac crest (DCIAPF) is considered a favourable single-flap option for oromandibular reconstruction. The aim of this study was to evaluate the effectiveness of venous superdrainage using the superficial circumflex iliac vein (SCIV) in the DCIAPF for oromandibular reconstruction. The data of 22 patients (12 female, 10 male) aged 10-76 years (median 53 years) who underwent simultaneous oromandibular reconstruction with a DCIAPF were reviewed retrospectively. Eleven patients received the DCIAPF with SCIV for superdrainage (group A) and another 11 patients received the conventional single-pedicled DCIAPF flap (group B). No flap loss occurred in either group. Venous congestion due to relative venous insufficiency was significantly more frequent in group B (P=0.045). There was no significant difference in the incidence of partial flap necrosis and wound dehiscence, or in the total operation time between the two groups. Superdrainage using the SCIV has the potential to reduce the incidence of venous congestion due to relative venous insufficiency in DCIAPF used for oromandibular reconstruction.

Abstract
Objective: The purpose of this study is to analyze the surveillance data of the Integrated HCV surveillance in Shanghai and provide a scientific basis for HCV's elimination strategies. Methods: Descriptive statistical analysis and multivariate logistic regression analysis were performed using the multi-dimension results of the Integrated HCV surveillance in Shanghai from 2014 to 2019. Data related to reported HCV cases, HCV gene subtypes surveillance, HCV behavioral risk factors surveillance and HCV-antibody testing results of the community-based general population and high-risk/key populations. Results: The reported incidence rate of acute hepatitis C in Shanghai decreased from 2014 to 2019 (Z=-4.07, P<0.01); meanwhile, the reported incidence rate of chronic hepatitis C met an upward trend (Z=10.26,P<0.01), with an annual average, reported incidence rates of 0.18 per 100 000 and 8.60 per 100 000, respectively. Seven hundred forty-four blood samples were subtyped with 16 subtypes from 4 genotypes (GT1, GT2, GT3, and GT6). Among above, 1b (324 cases, 43.55%), 3a (121 cases, 16.26%), 3b (111 cases, 14.92%) and 6a (47 cases, 6.32%) were the principal subtypes. The composition of genotypes varied with decreased 1b and increased 3b and 6a. The major risk factors for HCV infection were blood transfusion (OR=4.18, 95%CI: 2.79-6.27), surgery (OR=1.63, 95%CI: 1.26-2.12), sharing syringe (OR=4.18, 95%CI: 2.75-6.34), pedicure (OR=2.01, 95%CI: 1.54-2.62), sharing razors (OR=4.09, 95%CI:1.24-13.51), and unsafe beauty practices (OR=3.15, 95%CI: 2.13-4.65). HCV antibody screening of 11 groups of high-risk/key populations showed that drug users had the highest HCV-antibody positive rate of 18.81% (1 008/5 358). The anti-HCV positive rate of the general population was 0.16% (7/4 268), which was significantly lower than that of high-risk/key populations from the same year, 2.50%(501/20 002) (χ2=94.04, P<0.01). Conclusions: Shanghai is a low-endemic area of HCV. Constantly carrying out integrated surveillance and analysis is of great value for early identification of HCV infected people and its risk factors, timely adjustment of prevention and control strategies, and eliminating the public health threat of HCV.

Abstract
Objective: To explore the changing trends and influencing factors of AIDS-related and non-AIDS-related deaths after receiving antiretroviral therapy (ART) among HIV-positive individuals in Dehong Dai Jingpo autonomous prefecture (Dehong) from 2010 to 2019. Methods: Based on the Chinese National treatment database, HIV patients who initiated ART from 2010 to 2019 were included in the analysis. The cumulative incidence function was used to estimate the cumulative incidence of AIDS-related death and non-AIDS-related death, respectively. The Fine-Grey model was used to compare the differences between AIDS-related and non-AIDS-related deaths and analyze its influencing factors. Results: A total of 7 068 HIV-positive individuals were included, of which 388 were AIDS-related deaths and 570 were non-AIDS-related deaths. The cumulative mortality rate at years 1, 2, 3, 4, 5, 7 and 9 after receiving ART were 2.27%, 3.46%, 4.47%, 5.03%, 5.84%, 6.61%, 7.40% for AIDS-related deaths, and 1.63%, 3.11%, 4.68%, 6.02%, 7.42%, 10.49%, 12.75% for non-AIDS-related deaths, respectively. In the Fine-Grey model, older age at ART initiation, male, unmarried, injection drug use as the transmission route, lower baseline BMI, lower baseline CD4+ T cell counts, baseline FIB-4 score >3.25, and baseline anemia were risk factors for AIDS-related death. In contrast, age at ART initiation ≥45 years, male, Dai, and Jingpo minority ethnicities, unmarried, injection drug use as the transmission route, lower baseline BMI, baseline FIB-4 score >3.25, baseline eGFR <60 ml·min-1·1.73 m-2, and baseline anemia were risk factors for non-AIDS-related deaths. Conclusions: The cumulative mortality rate was low among HIV-positive individuals after receiving ART in Dehong during 2010-2019. The mortality of non-AIDS-related deaths was higher than that of AIDS-related deaths. There were also differences in the factors influencing AIDS-related and non-AIDS-related deaths and interventions should be intensified to target the influencing factors for non-AIDS-related deaths.

Abstract
Introduction Previous study has identified increased antithrombin III (ATIII) in patients with major depressive disorder (MDD), supporting ATIII as a potential biomarker for depression diagnosis. Objectives This study aimed to reveal the alteration of ATIII after occipital repetitive transcranial magnetic stimulation (rTMS), and illuminate its power to evaluate and predict the curative effects in MDD treatment. Methods A total of 90 MDD patients were recruited and further intervened with rTMS in occipital for individualized, standard or sham treatment for five days. Those of 74 patients underwent entire detection, including clinical assessments, blood collection and protein measurement. Results After treatment, decreased ATIII were detected in both the individualized and the standard group (p=0.000 and 0.001, respectively) instead of the sham one. Especially, the reduction in ATIII in the individualized group was associated with improvements in several neuropsychological assessments. Besides, ATIII at baseline in the standard group and after the individualized rTMS showed high performance to evaluate or predict the response to the 5-day treatment (AUC=0.771, 95%CI, 0.571-0.971; AUC=0.875, 95%CI, 0.714-1.000, respectively) and the remission in follow-up (AUC=0.736, 95%CI, 0.529-0.943; AUC=0.828, 95%CI, 0.656-1.000, respectively). Furthermore, both baseline ATIII and change in ATIII involved in the prediction of 24-item Hamilton Depression Rating Scale in the follow-up study with significant predictive values (p=0.0240 and 0.0233, respectively). Conclusions This study detected a reduction in ATIII after occipital rTMS, further revealed the relationships between change in ATIII and therapeutic response, and ultimately provided evidence for the potential of ATIII as a biomarker for the evaluation and prediction of antidepressive effect. Disclosure No significant relationships.

Abstract
OBJECTIVE To clarify the role of HMGA1 in influencing proliferation and migration abilities, and EMT (epithelial-mesenchymal transition) in gastric cancer (GC) cells. MATERIALS AND METHODS Differential expressions of HMGA1 in GC tissues and normal gastric tissues were analyzed in the GEPIA dataset. Its influence on overall survival of GC patients was evaluated as well. Moreover, HMGA1 levels in GC cells and gastric mucosal cells were detected. Regulatory effects of HMGA1 on the proliferation and migration abilities in SGC7901 and MGC803 cells were assessed through a series of functional experiments. At last, influences of HMGA1 on the expression levels of EMT-related genes, E-cadherin, Snail, and Slug were determined in GC cells. RESULTS Analysis of data in TCGA GEPIA dataset revealed that HMGA1 was upregulated in GC tissues, and GC patients with a high expression level of HMGA1 suffered poorer prognosis. In addition, HMGA1 was identically upregulated in GC cells, and the overexpression of HMGA1 improved the proliferation and migration abilities of SGC7901 and MGC803 cells, downregulated E-cadherin, and upregulated Snail and Slug in GC cells, while silence of HMAG1 yielded the opposite results CONCLUSIONS: HMGA1 is upregulated in GC tissues and predicts poor prognosis, and it aggravates the progression of GC via stimulating EMT.

Abstract
OBJECTIVE Glioma is one of the most common and invasive brain tumors worldwide. Long non-coding RNAs (LncRNAs) play an important role in the development of glioma. However, the regulatory mechanism of LncRNAs in glioma has not been fully elucidated. This study aimed to explore the interaction of lncRNA maternally expressed gene 3 (MEG3) and aberrant histone modification in glioma. MATERIALS AND METHODS The expression levels of MEG3 and miR-21-3p in glioma cells were measured by quantitative polymerase chain reaction (qPCR). EZH2 (enhancer of zeste homolog 2) and H3K27me3 expression in glioma cells were detected by Western Blot (WB). The binding site of the promoter of MEG3 by H3K27me3 was confirmed by ChIP-Real-time PCR. The direct target of MEG3 and miR-21-3p in glioma cells was measured by a luciferase reporter assay. Cell proliferation was detected by Cell Counting Kit-8 (CCK8), and cell invasion and migration were measured by Transwell assays. RESULTS EZH2 and miR-21-3p were upregulated and MEG3 was downregulated in glioma cells. Silencing of EZH2 inhibited cell proliferation, migration, and invasion in U87 and U251 cells. Meanwhile, the expression of H3K27me3 could be significantly inhibited by EZH2 interference. H3K27me3 protein can bind to MEG3 promoter directly. EZH2 inhibition and MEG3 down-expression in U87 cells reversed the effects of silencing of EZH2 on glioma cell growth and metastasis. However, EZH2 inhibition and MEG3 overexpression in U251 cells restricted cell proliferation, migration, and invasion. Furthermore, miR-21-3p was verified to interact with MEG3 by direct binding. Inhibition of MEG3 promoted U87 cell growth and metastasis, which was further strengthened following the co-transfection of si-MEG3 and miR-21-3p. Overexpressed MEG3 inhibited U251 cell growth and metastasis and a complete reversal of the results observed in the co-transfection of LV-MEG3 and miR-21-3p. CONCLUSIONS EZH2 was highly expressed in glioma cells and EZH2-mediated H3K27me3 enrichment on the MEG3 promoter regulated the growth and metastasis of glioma cells by targeting miR-21-3p. It potentially provided a new therapeutic marker targeting glioma.

Abstract
Objective: To investigate and compare the sub-foveal choroidal thickness (SFCT) in both eyes of patients with unilateral primary open-angle glaucoma (POAG) and healthy controls. Methods: Cross-sectional study. Patients with unilateral POAG and healthy controls were recruited from September 2018 to September 2019 in the Beijing Tongren Hospital. All subjects underwent enhanced depth imaging optical coherence tomography. The SFCT was measured at the fovea, and at 500 μm, 1 000 μm and 2 000 μm nasal and temporal to the fovea. Paired t test was conducted to compare the choroidal thickness between affected POAG eyes and unaffected fellow eyes. Analysis of covariance was conducted to compare the choroidal thicknesses between POAG eyes and controls. Multiple regression analysis determined the association between choroidal thickness and age, gender, spherical equivalent and mean deviation. Results: Seventy-five patients with unilateral POAG (mean age, 46 years; 48 males, 27 females) and 61 healthy controls (mean age, 44 years; 34 males, 27 females) were included in this study. The SFCT of POAG eyes was (244.41±83.18) μm, which was not significantly different from their unaffected fellow eyes [(254.28±88.92) μm, P>0.05] and controls (right eyes) [(272.98±55.87) μm, P>0.05]. Choroidal thickness at 2 000 μm nasal to the fovea was significantly decreased in the glaucomatous eyes compared with the unaffected fellow eyes [(167.84±70.44) vs. (188.84±89.06) μm, t=-3.55; P<0.01]. There were no significant differences among the glaucomatous eyes, unaffected fellow eyes and healthy controls in choroidal thickness at 500 μm and 1 000 μm nasal and temporal to the fovea, as well as at 2 000 μm temporal to the fovea (all P>0.05). The SFCT of POAG eyes was associated with mean deviation (β=14.66, P<0.05) and spherical equivalent (β=14.95, P<0.01) but not with age and gender (both P>0.05). Conclusions: The SFCT of affected eyes in patients with unilateral POAG has no significant difference from unaffected fellow eyes and healthy controls. However, the choroidal thickness at 2 000 μm nasal to the fovea is thinner in the POAG eyes as compared with the fellow eyes. A thinner SFCT is correlated with the loss of visual field and a higher spherical equivalent in myopia. This may suggest a contributing role of the perfusion of the choroid in the pathogenesis of glaucoma. (Chin J Ophthalmol, 2021, 57: 194-200).

Abstract
Nonmonotonic variation with collision energy (sqrt[s_{NN}]) of the moments of the net-baryon number distribution in heavy-ion collisions, related to the correlation length and the susceptibilities of the system, is suggested as a signature for the quantum chromodynamics critical point. We report the first evidence of a nonmonotonic variation in the kurtosis times variance of the net-proton number (proxy for net-baryon number) distribution as a function of sqrt[s_{NN}] with 3.1 σ significance for head-on (central) gold-on-gold (Au+Au) collisions measured solenoidal tracker at Relativistic Heavy Ion Collider. Data in noncentral Au+Au collisions and models of heavy-ion collisions without a critical point show a monotonic variation as a function of sqrt[s_{NN}].

Abstract
Nasal alar defects lead to facial disfigurement, and nasal ala reconstruction is an important treatment option. The vascularized composite auricular flap based on the superficial temporal artery is an ideal option for a full-thickness nasal alar defect. However, the pedicle length and the discrepancy in artery diameter between the recipient vessel and flap pedicle continue to be major problems for free auricular composite tissue transfer. Considering that the angular artery is occasionally absent and the course of the infraorbital segment of the facial vein is constant, there are often no suitable vessels around the recipient site for anastomoses to the short pedicle of the flap. In the absence of a suitable recipient artery, an infraorbital segment of the facial vein measuring 2.5cm in length was taken as a graft for the anastomosis of the superficial temporal artery and superior labial artery. End-to-end anastomosis was performed easily. The flap was inset to reconstruct the contralateral ala. The facial vein graft for anastomosis of the superficial temporal artery and branch of the facial artery is a reliable and easy method to resolve the problem of a short pedicle and large artery discrepancy for nasal ala reconstruction with a vascularized composite helical rim flap.

Abstract
PURPOSE Gitelman syndrome (GS) is an autosomal recessive renal tubular disease that arises as a consequence of mutations in the SLC12A3 gene, which codes for an Na-Cl cotransporter (NCC) in distal renal tubules. This study was designed to explore the mutations associated with GS in an effort to more fully understand the molecular mechanisms governing GS. METHODS We analyzed SLC12A3 mutations in a pedigree including a 42-year-old male with GS as well as four related family members over three generations using Sanger and next generation sequencing approaches. We additionally explored the functional ramifications of identified mutations using both Xenopus oocytes and the HEK293T cell line. RESULTS We found that the subject with GS exhibited characteristic symptoms including sporadic thirst, fatigue, excess urination, and substantial hypokalemia and hypocalciuria, although magnesium levels were normal. Other analyzed subjects in this pedigree had normal laboratory findings and did not exhibit clear signs of GS. Sequencing analyses revealed that the GS subject exhibited a homozygous missense mutation (c.2874C > G, p.N958K) in exon 24 of SLC12A3. Both parents of this GS subject, as well as his older brother and daughter all exhibited heterozygous mutations at this same site. Functional analyses in Xenopus oocytes indicated that this mutated SLC12A3 gene encodes a protein which fails to mediate normal sodium transport, and when this mutant gene was expressed in HEK293T cells, we observed significant increases in endoplasmic reticulum (ER)-stress pathway activation. CONCLUSION The p.N958K mutation in exon 24 of SLC12A3 can trigger GS at least in part via enhancing ER stress responses.

Abstract
OBJECTIVE Intervertebral disc degeneration (IDD) represents major cause of low back pain. Quercetin (QUE) is one of the approved senolytic agents. In this study, we evaluated the protective effects of QUE on IDD development and its underlying mechanism. METHODS Effects of senolytic agent QUE on the viability of nucleus pulposus cells (NPCs) were measured by CCK-8 assays and EdU staining. The senescence associated secreted phenotype (SASP) factors expressions were measured by qPCR, western blot, and ELISA; and NF-κB pathway was detected by immunofluorescence and western blot. Molecular docking was applied to predict the interacting protein of QUE; while Nrf2 was knocked down by siRNAs to confirm its role in QUE regulated senescence phenotype. X-ray, MRI, Hematoxylin-Eosin and Safranin O-Fast green staining were performed to evaluate the therapeutic effects of QUE on IDD in the puncture-induced rat model. RESULTS In in vitro experiments, QUE inhibited SASP factors expression and senescence phenotype in IL-1β-treated NPCs. Mechanistically, QUE suppressed IL-1β induced activation of the NF-κB pathway cascades; it was also demonstrated in molecular docking and knock down studies that QUE might bind to Keap1-Nrf2 complex to suppress NF-κB pathway. In vivo, QUE ameliorated the IDD process in the puncture-induced rat model. CONCLUSIONS Together the present work suggests that QUE inhibits SASP factors expression and senescence phenotype in NPCs and ameliorates the progression of IDD via the Nrf2/NF-κB axis, which supports senolytic agent QUE as a potential therapeutic agent for the treatment of IDD.

Abstract
AIM To evaluate the lung function of coronavirus disease 2019 (COVID-19) patients using oxygen-enhanced (OE) ultrashort echo time (UTE) MRI. MATERIALS AND METHODS Forty-nine patients with COVID-19 were included in the study. The OE-MRI was based on a respiratory-gated three-dimensional (3D) radial UTE sequence. For each patient, the percent signal enhancement (PSE) map was calculated using the expression PSE = (S100% – S21%)/S21%, where S21% and S100% are signals acquired during room air and 100% oxygen inhalation, respectively. Agreement of lesion detectability between UTE-MRI and computed tomography (CT) was performed using the kappa test. The Mann–Whitney U-test was used to evaluate the difference in the mean PSE between mild-type COVID-19 and common-type COVID-19. Spearman's test was used to assess the relationship between lesion mean PSE and lesion size. Furthermore, the Mann–Whitney U-test was used to evaluate the difference in region of interest (ROI) mean PSE between normal pulmonary parenchyma and lesions. The Kruskal–Wallis test was applied to test the difference in the mean PSE between different lesion types. RESULTS CT and UTE-MRI reached good agreement in lesion detectability. Ventilation measures in mild-type patients (5.3 ± 5.5%) were significantly different from those in common-type patients (3 ± 3.9%). Besides, there was no significant correlation between lesion mean PSE and lesion size. The mean PSE of COVID-19 lesions (3.2 ± 4.9%) was significantly lower than that of the pulmonary parenchyma (5.4 ± 3.9%). No significant difference was found among different lesion types. CONCLUSION OE-UTE-MRI could serve as a promising method for the assessment of lung function or treatment management of COVID-19 patients.

Abstract
Objective: To compare the population characteristics, the positive rate of screening, the detection rate of breast cancer, early diagnosis rate and the cost between the mass screening group and opportunistic screening group of breast cancer. Methods: This study is a prospective multicenter cohort study conducted from January 1, 2014 to December 31, 2016. The participants were enrolled for mass screening or opportunistic screening of breast cancer. After completing the questionnaire, all the participants received breast physical examination and breast ultrasound examination every year for 3 rounds by year. The participants' characteristics and screening results of the two groups were compared by χ2 test, Fisher exact test or Wilcoxon rank-sum test. Results: A total of 20 080 subjects were enrolled. In the mass screening group, 9 434 (100%), 8 111 (85.98%) and 3 940 (41.76%) cases completed the 3 rounds of screening, and 10 646 (100%), 6 209 (58.32%) and 2 988 (28.07%) cases in the opportunistic screening group, respectively. In the opportunistic screening group, the proportions of less than 3 months lactation (1 275/9 796 vs. 1 061/8 860, χ²=4.597, P=0.032), non-fertility (850/10 646 vs. 574/9 434, χ²=27.400, P<0.01), abortion history (6 384/10 646 vs. 5 062/9 434, χ²=81.232, P<0.01), postmenopausal (2 776/10 646 vs. 2 217/9 434, χ²=17.757, P<0.01), long-term oral contraceptives(>6 months) (171/10 646 vs. 77/9 434, χ²=25.593, P<0.01) and family history of breast cancer in first-degree relatives (464/10 646 vs. 236/9 434, χ²=51.257, P<0.01) were significantly higher than those in mass screening group. The positive rate of screening (514/10 646 vs. 128/9 434, χ²=194.736, P<0.01), the detection rate of breast cancer (158/10 646 vs. 13/9 434, χ²=107.374, P<0.01), and positive rate of biopsy (158/452 vs. 13/87, χ²=13.491, P<0.01) in the opportunistic screening group were significantly higher than those of the mass screening group. The early diagnosis rate of the mass screening group was significantly higher than the opportunistic screening group (10/12 vs. 66/141, χ²=5.902, P=0.015). The average cost for detecting each breast cancer case of the mass screening group was 215 038 CNY, which was 13.6 times of the opportunistic screening group (15 799 CNY/case). In the opportunistic screening group, the positive rate of biopsy in primary hospitals was significantly lower than that in large-volume hospitals (79/267 vs. 79/185, χ²=8.267, P=0.004), but there was no significant difference in the mass screening group (6/37 vs. 7/50, χ²=0.082, P=0.774). Conclusions: Breast cancer screening can improve early detection rate. Compared with the mass screening mode, the opportunistic screening mode has the advantages of higher proportion of high-risk factors, higher positive rate of screening, higher detection rate of breast cancer, higher positive rate of biopsy, and lower cost of screening. However, the early diagnosis rate of breast cancer of opportunistic screening is lower than that of mass screening. The positive rate of opportunistic screening in primary hospitals is lower than that of large-volume hospitals. The two screening modes have their own advantages and should be chosen according to local conditions of different regions in China.

EUROPEAN REVIEW FOR MEDICAL AND PHARMACOLOGICAL SCIENCES 2021; 24:1408-1419.

Abstract
OBJECTIVE This study aimed to explore the role of miR-155-5p in middle cerebral artery occlusion/reperfusion (MCAO/R) model in rats and oxygen-glucose deprivation/reoxygenation (OGD/R)-induced SH-SY5Y cells. In addition, this study also aimed to explore the underlying mechanisms to expect that miR-155-5p may be investigated as a new and effective diagnostic and therapeutic target for ischemic stroke. MATERIALS AND METHODS The in vivo MCAO/R rat model and in vitro OGD/R cell model were established. The miR-155-5p mRNA expression was detected by quantitative Reverse Transcription-Polymerase Chain Reaction (qRT-PCR). Dual specificity ATPase (DUSP) 14 was predicted to be a potential target of miR-155-5p by TargetScan. The targeting relationship was confirmed by Luciferase assay. The cell viability was determined using the Cell Counting Kit-8 (CCK-8). The expression level of inflammatory cytokines, including tumor necrosis factor alpha (TNF-α), interleukin-1β (IL-1β), and interleukin-6 (IL-6) levels were detected by Enzyme-Linked Immunosorbent Assay (ELISA). Western blot was used to detect the protein expression of DUSP14, the apoptotic protein Cleaved cysteine-aspartic acid protease (caspase)-3, and Cleaved PARP, as well as nuclear factor kappa B (NF-κB) and MAPKs signaling pathways related proteins. RESULTS MiR-155-5p was upregulated in both MCAO/R rats and OGD/R-induced SH-SY5Y cells. MiR-155-5p knockdown inhibited OGD/R-induced cell injury and inflammation, as well as MCAO/R-induced brain injury. MiR-155-5p regulated the NF-κB and MAPKs signaling pathways by targeting DUSP14. DUSP14 knockdown partially reversed the protective effect of miR-155-5p knockdown on OGD/R-induced SH-SY5Y cell injury and inflammation. CONCLUSIONS MiR-155-5p accelerates cerebral I/R injury via targeting DUSP14 by regulating NF-κB and MAPKs signaling pathways. Inhibition of miR-155-5p significantly reduces apoptosis and brain injury. These results indicated that miR-155-5p plays a key role in cerebral I/R injury and has the potential to be explored as a new target for ischemic stroke.

Abstract
Because hyperpolarization-activated cyclic nucleotide-gated (HCN) ion channels modulate the excitability of cortical and hippocampal principal neurons, these channels play a key role in the hyperexcitability that occurs during the development of epilepsy after a brain insult, or epileptogenesis. In epileptic rats generated by pilocarpine-induced status epilepticus, HCN channel activity is downregulated by two main mechanisms: a hyperpolarizing shift in gating and a decrease in amplitude of the current mediated by HCN channels, Ih. Because these mechanisms are modulated by various phosphorylation signaling pathways, we hypothesized that phosphorylation changes occur at individual HCN channel amino acid residues (phosphosites) during epileptogenesis. We collected CA1 hippocampal tissue from male Sprague Dawley rats made epileptic by pilocarpine-induced status epilepticus, and age-matched naïve controls. We also included resected human brain tissue containing epileptogenic zones (EZs) where seizures arise for comparison to our chronically epileptic rats. After enrichment for HCN1 and HCN2 isoforms by immunoprecipitation and trypsin in-gel digestion, the samples were analyzed by mass spectrometry. We identified numerous phosphosites from HCN1 and HCN2 channels, representing a novel survey of phosphorylation sites within HCN channels. We found high levels of HCN channel phosphosite homology between humans and rats. We also identified a novel HCN1 channel phosphosite S791, which underwent significantly increased phosphorylation during the chronic epilepsy stage. Heterologous expression of a phosphomimetic mutant, S791D, replicated a hyperpolarizing shift in Ih gating seen in neurons from chronically epileptic rats. These results show that HCN1 channel phosphorylation is altered in epilepsy and may be of pathogenic importance.

Abstract
OBJECTIVES This study systematically reviewed evidence from interventions on the effect of front-of-package (FOP) nutrition labeling on food purchases. STUDY DESIGN The study design used in this study is a systematic review. METHODS Keyword search was performed in PubMed, Web of Science, Scopus, and Cochrane Library. RESULTS Fifteen studies (10 randomized controlled trials, four pre-post studies, and one case-control study) met the eligibility criteria and were included in the review. Five studies were conducted in a controlled setting through the establishment of an online virtual supermarket or physical laboratory food store solely for the intervention. In contrast, the remaining ten studies were conducted in a naturalistic setting where people commonly purchase foods (e.g., supermarket, grocery store, school/hospital cafeteria, or vending machine). FOP labels assessed included traffic lights, health star rating, daily intake guides, health warnings, and high sugar symbol labels. Compared with the control, FOP labels were effective for helping participants make healthier food purchase decisions in five of the 12 studies that assessed traffic lights labels, in one of the two studies that assessed health warning labels, and in one study that assessed high sugar symbol labels. Three assessed health star ratings and one assessed daily intake guide labels, but none revealed an effect on food purchases compared with the control. CONCLUSIONS Findings on the effectiveness of FOP nutrition labels in 'nudging' consumers toward healthier food purchases remain mixed and inconclusive. Future studies should examine other types of FOP labels beside the traffic lights labels and explore the different effects by consumer affordability, population subgroup, and shopping environment.

Abstract
Neutrophils and neutrophil extracellular traps (NETs) have been shown to be involved in coagulation. However, the interactions between neutrophils or NETs and fibrin(ogen) in clots, and the mechanisms behind these interactions are not yet fully understood. In this in vitro study, the role of neutrophils or NETs on clot structure, formation and dissolution was studied with a combination of confocal microscopy, turbidity and permeation experiments. Factor (F)XII, FXI and FVII-deficient plasmas were used to investigate which factors may be involved in the procoagulant effects. We found both neutrophils and NETs promote clotting in plasma without the addition of other coagulation triggers, but not in purified fibrinogen, indicating that other factors mediate the interaction. The procoagulant effects of neutrophils and NETs were also observed in FXII- and FVII-deficient plasma. In FXI-deficient plasma, only the procoagulant effects of NETs were observed, but not of neutrophils. NETs increased the density of clots, particularly in the vicinity of the NETs, while neutrophils-induced clots were less stable and more porous. In conclusion, NETs accelerate clotting and contribute to the formation of a denser, more lysis resistant clot architecture. Neutrophils, or their released mediators, may induce clotting in a different manner to NETs, mediated by FXI.
