PTX3 activates POSTN and promotes the progression of glioblastoma via the MAPK/ERK signalling axis.

BACKGROUND: Intrinsic brain tumours such as glioblastoma (GBM) are believed to develop from neuroglial stem or progenitor cells. GBM accounts for approximately half of gliomas. GBM has a poor prognosis and a low 5-year survival rate. Pentraxin 3 (PTX3) is overexpressed in GBM, but the potential mechanism is unclear. METHODS: Glioblastoma data from the TCGA and CGGA databases were used to analyse PTX3 expression. Subsequently, in vivo and in vitro experiments were conducted to verify the effect of PTX3 silencing in glioma cells on EMT like process and GSC maintenance. The JASPAR database was used to predict the downstream genes of PTX3. POSTN is a novel target gene of PTX3 in gliomas, and this finding was validated using a luciferase reporter gene assay. Western blotting and KEGG enrichment analysis were used to predict the downstream pathway of POSTN, and it was found that the MAPK/ERK pathway might be related to the function of POSTN. RESULTS: GBM tissues have higher levels of PTX3 expression than normal brain tissues (NBTs). In functional tests, PTX3 promoted the EMT like process of GBM cells while maintaining the stem cell characteristics of GBM stem cells and enhancing their self-renewal. Moreover, we performed a dual luciferase reporter experiment to confirm that PTX3 binds to the POSTN promoter region. In addition, the expression of key proteins in the MAPK/ERK signalling pathway was increased after PTX3 overexpression. CONCLUSION: POSTN is a direct target of PTX3 that promotes GBM growth via the MAPK/ERK signalling pathway.

CircNDC80 promotes glioblastoma multiforme tumorigenesis via the miR-139-5p/ECE1 pathway.

BACKGROUND: Circular RNAs (circRNAs) have been shown to be essential for the emergence and growth of different cancers. However, further research is required to validate the function of circRNA in glioblastoma (GBM). METHODS: CircNDC80 expression in both normal brain tissues (NBTs) and glioma tissues was determined using real-time PCR. The impact of circNDC80 on GBM cell proliferation, migration, and invasion was then confirmed by CCK-8, colony formation, EdU incorporation, Transwell, and wound healing assays. To determine how circNDC80 affects the capacity of glioma stem cells (GSCs) to maintain their stemness and self-renewal, a CellTiter-Glo assay, clonogenic assay and extreme limiting dilution assay were utilized. To ascertain the impact of circNDC80 in vivo, intracranial xenograft models were established. RESULTS: When compared to NBT, glioblastoma tissue had a higher level of circNDC80 expression. In functional assays, circNDC80 promoted glioblastoma cell proliferation, migration, and invasion, while sustaining the stemness and fostering the self-renewal of glioma stem cells. In addition, a dual luciferase reporter assay and circRIP were used to verify that circNDC80 simultaneously affects the expression of ECE1 mRNA by sponging miR-139-5p, and a rescue experiment was used to verify the above results further. CONCLUSIONS: According to our research, circNDC80 is an oncogenic factor that promotes glioblastoma through the miR-139-5p/ECE1 pathway. This implies that circNDC80 may be employed as a novel therapeutic target and a possible predictive biomarker.

Comparison of the Efficacy of Subosseous Window Neuro-Endoscopy and Minimally Invasive Craniotomy in the Treatment of Basal Ganglia Hypertensive Intracerebral Hemorrhage.

OBJECTIVE: To compare the perioperative indexes and long-term effects of craniotomy and neuro-endoscopic hematoma removal in patients with hypertensive intracerebral hemorrhage (HICH) in the basal ganglia region. METHODS: This study involved 128 patients with HICH in the basal ganglia region who were admitted to our hospital from February 2020 to June 2022. They were divided into 2 groups according to the random number table method. The craniotomy group (n = 70) underwent microsurgery with small bone window craniotomy with a side cleft, and the neuro-endoscopy group (n = 58) underwent small bone window neuro-endoscopic surgery. A 3-dimensional Slicer was used to calculate the hematoma volume and clearance rate and the postoperative brain tissue edema volume. The operation time, intraoperative blood loss, postoperative intracranial pressure, complications, mortality, and improvement in the modified Rankin scale score at 6 months postoperatively were compared between the two groups. RESULTS: The clearance rate was significantly higher in the neuro-endoscopy group than in the craniotomy group (94.16% ± 1.86% versus 90.87% ± 1.89%, P < 0.0001). The operation time was significantly lower in the neuro-endoscopy group than in the craniotomy group (89.9 ± 11.7 versus 203.7 ± 57.6 min, P < 0.0001). Intraoperative blood loss was significantly higher in the craniotomy group (248.31 ± 94.65 versus 78.66 ± 28.96 mL, P < 0.0001). The postoperative length of stay in the intensive care unit was 12.6 days in the neuro-endoscopy group and 14.0 days in the craniotomy group with no significant difference ( P = 0.196). Intracranial pressure monitoring showed no significant difference between the two groups on postoperative days 1 and 7. Intracranial pressure was significantly higher in the craniotomy group than in the neuro-endoscopy group on postoperative day 3 (15.1 ± 6.8 versus 12.5 ± 6.8 mm Hg, P = 0.029). There was no significant difference in the mortality or outcome rate at 6 months postoperatively between the two groups. CONCLUSIONS: In patients with HICH in the basal ganglia region, neuro-endoscopy can significantly improve the hematoma clearance rate, reduce intraoperative hemorrhage and postoperative cerebral tissue edema, and improve surgical efficiency. However, the long-term prognosis of patients who undergo craniotomy through the lateral fissure is similar to that of patients who undergo neuro-endoscopic surgery.

Nutrient removal effect and characteristics of integrated floating beds at low temperature.

To investigate the effect of combined floating beds on nutrient removal under low temperature, an integrated floating bed with corn flakes (IFB-CF) and an integrated floating bed with light ceramsite (IFB-LC) were constructed in parallel. IFB-LC was used as control group under water temperatures of 9.3-14 °C and a water exchange time of 168 h. Nitrogen and phosphorus removal efficiency, the nutrient level of a hydrophyte (Oenanthe javanica), and the microbial population characteristics of the combined floating bed were investigated. For IFB-CF removal efficiencies, the degradation quantities of total nitrogen (TN), NO3--N, and NH4+-N for IFB-CF were 13.58 ± 0.67 mg/L, 4.40 ± 0.61 mg/L, and 9.21 ± 0.38 mg/L, respectively; in contrast, degradation quantities for IFB-LC were lower (6.41 ± 1.47 mg/L, 2.15 ± 0.40 mg/L, and 5.95 ± 0.46 mg/L, respectively). The reductions in COD (Chemical Oxygen Demand, using K2Cr2O7 as oxidizer) for IFB-LC and IFB-CF were 86.89% and 66.06%, respectively. Using the MiSeq high throughput sequencing method, we analysed microbial community structure and diversity on the base material surface of the IFB-CF and IFB-LC. The results showed 15 phyla, 165 genera, and 78 families on the surface of the IFB-CF. The phylum, genus, and family with the highest abundances were Proteobacteria (48.29%), Trichococcus (10.39%), and Comamonadaceae (12.45%), respectively. We identified 15 phyla, 144 genera, and 93 families on the surface of the IFB-LC. The phylum, genus, and family with the highest abundances were Proteobacteria (46.10%), Dyadobacter (22.67%), and Cytophagaceae (28.75%), respectively. The Chao, ACE, and Shannon & Simpson indices for the IFB-LC were 4081, 6295, and 5.10, and 0.05, respectively; for the IFB-CF they were 4938, 7461, 5.77, and 0.02, respectively. Catalase (CAT) and Peroxidase (POD) concentrations in Oenanthe javanica for IFB-LC were 35.48 u/gFW/min and 1.03 u/gFW/min, respectively; for IFB-CF they were 32.33 u/gFW/min and 1.25 u/gFW/min, respectively. The nutritional energies of IFB-CF and IFB-LC were 107 kJ/100g and 84 kJ/100g. Using the Mondal model of TN removal, k (half-saturation constant) values for IFB-LC and IFB-CF were 35.67 mg/L and 39.23 mg/L, respectively, with a correlation coefficient (R2) of 0.97.

Nitrogen Removal from Water Resource Recovery Facility Secondary Effluent Using a Bioreactor.

Solid-phase denitrification technology can potentially be used to remove nitrogen compounds, such as total nitrogen and nitrate nitrogen (NO3(-)-N), from wastewater. In this study, the authors made use of an internal-circulation baffled biofilm reactor in which filamentous bamboo acted as a biocarrier for the removal of nitrogen (N) from water resource recovery facility (WRRF) secondary effluent. A laboratory-scale experiment was conducted to assess the efficacy and mechanisms of N removal from the WRRF secondary effluent operated in continuous-flow mode. Results indicated that total nitrogen and NO3(-)-N removal rates reached 66.58 to 75.23% and 75.6 to 85.6%, respectively. Infrared spectrum analysis indicated biodegradation in the filamentous bamboo. A comparison of this method with the use of filamentous plastics as biocarriers indicated that higher NO3(-)-N removal (as volumetric loading) and lower nitrite nitrogen accumulation rates were obtained when filamentous bamboo was used as a biocarrier. A NO3(-)-N removal volumetric loading of 2.09 mg/L·h was reached when using bamboo as a single solid carbon source. These results confirm that filamentous bamboo can be used as an alternative to inert biocarriers in WRRF secondary effluent treatment systems.

MiR-218 Inhibited Growth and Metabolism of Human Glioblastoma Cells by Directly Targeting E2F2.

In recent years, microRNA has become a hotspot in research on diseases, especially in the initiation and progression of different types of cancer. In this study, we found that miR-218 could inhibit growth and metabolism in gliomas by directly targeting E2F2. First, we obtained data from the Chinese Glioma Genome Atlas (CGGA) database to analyze miR-218 expression in different grades of gliomas. The effects of miR-218 on cell cycle progression and cell proliferation in U87 and U251 cell lines were investigated by flow cytometry, specifically CCK8 assay and tablet cloning, respectively. Glucose consumption and lactate production of glioma cell lines were measured by correlative test kits. Furthermore, we used Western blot analysis and luciferase reporter assay to identify the direct and functional target of miR-218. Data from the CGGA database and real-time quantitative reverse transcription-PCR demonstrated that miR-218 was obviously reduced in human glioblastoma tissues, as well as in the cell lines. When miR-218 level was elevated in vitro, cell cycle progression was arrested in the G1 phase, and cell proliferation was dramatically inhibited. Both glucose consumption and lactate production of glioma cells were significantly reduced. Western blot analysis and luciferase reporter assay revealed that E2F2 was a direct target of miR-218 in glioma cells. This investigation demonstrated that elevated E2F2 expression could partly weaken the effect of miR-218 in vitro. This study also showed that miR-218 may be a repressor in glioma by directly targeting E2F2, as well as a potential therapeutic target in gliomas.

Enhanced piezoelectric and mechanical properties of AlN-modified BaTiO3 composite ceramics.

BaTiO3-xAlN (BT-xAlN) composite ceramics were prepared by conventional solid state reaction sintering. The effects of the AlN content on the crystalline structures, densities, and electrical and mechanical properties of the BT ceramics were investigated. The BT-1.5%AlN ceramic exhibits a good piezoelectric constant of 305 pC N(-1) and an improved Vickers hardness of 5.9 GPa. The enhanced piezoelectricity originates from interactions between defect dipoles and spontaneous polarization inside the domains due to the occurrence of local symmetry, caused by the preferential distribution of the Al(3+)-N(3-) pairs vertical to the c axis. The hardening of the material is attributed to the improved density, and particle and grain boundary strengthening. Our work indicates that if a suitable doping ion pair is designed, lead-free ceramic systems prepared from ordinary raw materials by a conventional sintering method have a high probability of exhibiting good piezoelectric and mechanical properties simultaneously.

Risk factors for benign paroxysmal positional vertigo and construction of a nomogram predictive model.

BACKGROUND: To analyze the risk factors for benign paroxysmal positional vertigo (BPPV) and to construct a predictive nomogram model. METHODS: In this retrospective study, 312 participants were enrolled, including 164 BPPV patients and 148 healthy subjects without BPPV. Risk predictors for BPPV were identified using univariate and multivariate analyses, and a clinical nomogram was constructed. The predictive accuracy was assessed by unadjusted concordance index (C-index) and calibration plot. RESULTS: Univariate and multivariate regression analysis identified stroke (95% CI, 0.575-5.954; P=0.022), hyperlipidemia (95% CI, 0.471-4.647; P=0.003), chronic suppurative otitis media (95% CI, 1.222-45.528; P=0.005), cervical spondylosis (95% CI, 1.232-3.017; P=0.005), and osteoporosis (95% CI, 1.130-3.071; P=0.001) were the independent risk factors for BPPV. These risk factors were used to construct a clinical predictive nomogram. The regression equation was: logit (P) = -6.820 + 0.450 * stroke + hyperlipidemia * 0.312 + chronic suppurative otitis media * 0.499 + cervical spondylosis * 0.916 + osteoporosis * 0.628. The calibration curves demonstrated excellent accuracy of the predictive nomogram. Decision curve analysis showed that the predictive model is clinically applicable when the threshold probability was between 20% and 60%. CONCLUSIONS: Stroke, hyperlipidemia, chronic suppurative otitis media, cervical spondylosis and osteoporosis are independent risk predictors for BPPV. The developed nomogram is useful in predicting the risk of BPPV.

TGF-ß-activated circRYK drives glioblastoma progression by increasing VLDLR mRNA expression and stability in a ceRNA- and RBP-dependent manner.

BACKGROUND: The TGF-ß signalling pathway is intricately associated with the progression of glioblastoma (GBM). The objective of this study was to examine the role of circRNAs in the TGF-ß signalling pathway. METHODS: In our research, we used transcriptome analysis to search for circRNAs that were activated by TGF-ß. After confirming the expression pattern of the selected circRYK, we carried out in vitro and in vivo cell function assays. The underlying mechanisms were analysed via RNA pull-down, luciferase reporter, and RNA immunoprecipitation assays. RESULTS: CircRYK expression was markedly elevated in GBM, and this phenotype was strongly associated with a poor prognosis. Functionally, circRYK promotes epithelial-mesenchymal transition and GSC maintenance in GBM. Mechanistically, circRYK sponges miR-330-5p and promotes the expression of the oncogene VLDLR. In addition, circRYK could enhance the stability of VLDLR mRNA via the RNA-binding protein HuR. CONCLUSION: Our findings show that TGF-ß promotes epithelial-mesenchymal transition and GSC maintenance in GBM through the circRYK-VLDLR axis, which may provide a new therapeutic target for the treatment of GBM.

Recycling cobalt from spent lithium-ion batteries for designing the novel cobalt nitride followers: Towards efficient overall water splitting and advanced zinc-air batteries.

Although cobalt nitride (CoN)-based nanomaterials have been widely designed as advanced oxygen evolution reaction (OER), hydrogen evolution reaction (HER), and oxygen reduction reaction (ORR) catalysts, the continuous consumption of lithium-ion batteries (LIBs) has led to a high price of cobalt metal. Therefore, in the future, recycling valuable Co elements from spent devices and boosting their service efficiency will inevitably promote the utilization of Co-based materials in water splitting and zinc-air batteries (ZABs). Herein, we realize the Co recycling from spent LIBs by a simple hydrometallurgy method. Under the assistance of hexamethylenetetramine and polystyrene spheres, after the hydrothermal and pyrolysis treatment in the NH3 atmosphere, the as-reclaimed cobalt oxalates were successfully transformed into novel three-dimensional (3D) CoN nanoflowers (denoted as CoN NFs). Benefiting from the unique 3D flower-like architectures, intrinsic high conductivity, large surface area, uniformly dispersed CoN nanoparticles, and the synergistic effect between Co3N and CoO phases, the 3D flower-like CoN NFs exhibited excellent OER catalytic activity. The performance was much better than commercial RuO2 in the 1.0 M KOH solution. Furthermore, the CoN NFs-based water splitting cell needed a voltage of 1.608 V to achieve the current density of 10 mA cm-2, which is even 16 mV smaller than that of Pt/C||RuO2 benchmark (1.624 V). Meanwhile, the CoN NFs-derived ZAB exhibited a high peak power density of 107.3 mW cm-2 (vs. 103.2 mW cm-2 of Pt/C-RuO2-based ZAB) and a low charge-discharge voltage gap (0.93 V vs. 1.43 V of Pt/C-RuO2-based ZAB). Due to the excellent structural and elemental stabilities, the corresponding water splitting cell and ZAB had outstanding durability. This work successfully explored an advanced industrial chain from recycling Co metal in spent devices to designing the high-efficiency HER/OER/ORR electrocatalysts for advanced water splitting devices and ZABs. This will further promote the value-added utilization of valuable Co metal in various energy storage or conversion devices.

Ultrasound-guided injection acupotomy as a minimally invasive intervention therapy for cervical spondylotic radiculopathy: a randomized control trial.

OBJECTIVE: To explore the efficacy and safety of ultrasound-guided injection acupotomy as a minimally invasive intervention treatment of cervical spondylotic radiculopathy (CSR). METHODS: 160 CSR subjects were recruited who met the inclusion criteria in our hospital from October 2019 to December 2021. The subjects were randomly divided into the experimental and control group, with 80 cases in each. The experimental group received ultrasound-guided injection acupotomy as a minimally invasive intervention therapy. The control group received ultrasound-guided selective nerve root block (SNRB). The Odom's criteria clinical curative effect, visual analogue scale (VAS), neck disability index (NDI), and 36-Item Short Form Health Survey questionnaire (SF-36) were used to evaluate the outcome of subjects at several different points in time. RESULTS: At 30 min and 1 month after the end of treatment, there was no significant difference in any scores. However, after six months, the excellent and good rate was better in the experimental group compared to the control (RD = 0.175; 95% CI, 0.044-0.300, p = 0.009). The total effective rate was also better in the experimental group (RD = 0.126; 95% CI, 0.021-0.232, p = 0.018). In contrast, the VAS score (MD = -0.500; 95% CI, -1.000-0.000, p = 0.030) and NDI score (MD = -6.460; 95% CI, -11.067 to -1.852, p = 0.006) were lower in the experimental group compared to the control. The total SF-36 score was higher in the experimental group (MD = 7.568; 95% CI, 2.459-12.677, p = 0.004). CONCLUSION: Ultrasound-guided injection acupotomy minimally invasive interventional treatment of CSR has no significant difference in short-term curative effect compared with ultrasound-guided SNRB, but the data indicators are significantly better than the latter at 6 months after the end of the course of treatment, showing better long-term efficacy.

A new locus in chromosome 2q37-qter is associated with posterior polar cataract.

PURPOSE: To study the genetic basis of autosomal dominant posterior polar cataracts in two Chinese pedigrees. MATERIALS AND METHODS: Peripheral blood samples were collected and genomic DNA was isolated. A genome-wide scan, using microsatellite markers at approximately 10-cm intervals and additional microsatellite markers for the positive region, was performed. Haplotype data were processed using Cyrillic software (version 2.1) to define the region of the disease gene. Mutation analysis was carried out for candidate genes. Sequencing data were analyzed with the software Sequence Scanner v1.0. RESULTS: A maximum two-point LOD score (Z (max)) of 2.53 and 2.03 was obtained at marker D2S125 with recombination θ = 0.00 in the two families. The possible disease genes were located at approximately 8.44-cM between the marker D2S125 and the terminal of chromosome 2q, namely, 2q37-qter. Candidate genes, such as Gamma-crystallins (CRYGA-D), septin 2 (SEPT2), aquaporin 12B (AQP12B), and chemokine orphan receptor 7 (CXCR7), were sequenced but no causative mutations were found. CONCLUSIONS: Our results suggest that an unidentified gene in chromosome 2q37-qter is associated with posterior polar cataract, which may have an implication in understanding the genetic and molecular mechanisms of cataracts.

Reduction of nitrate by bimetallic Fe/Ni nanoparticles.

Bimetallic Fe/Ni nanoparticles were synthesized and their nitrate reduction capacity was studied. Nitrate (354 mg L(-1), equal to 5.71 mmol L(-1)) reduction was performed using Fe/Ni nanoparticles with various Ni contents (1.0, 5.0, 10 and 20%) in an unbuffered condition. Optimum nitrate reduction rate (1.03 +/- 0.087 x 10(-4) mol x min(-1) x greduc(-1)) was obtained with 5.0% nano-scale Fe/Ni, while only 25% nitrate (1.05 +/- 0.091 x 10(-5) mol x min(-1) x greduc(-1)) was transformed by nano-scale Fe(0) within the same reaction time, which means that these bimetallic nanoparticles are obviously more reactive than monometallic nano-scale Fe(0). For this bimetallic system a near-neutral initial pH (6.5) is more favourable than an acidic condition (2.0 and 4.0). Relatively air-stable nano-scale Fe/Ni particles were developed by slowly aging them for 22 h and exhibited similar reactivity to freshly synthesized nano-scale Fe(0). Although undesirable transformation of nitrate (91.0 +/- 0.37%) to ammonium was observed in this study, Fe/Ni particles showed a much higher nitrate reduction rate and an optimum reduction rate at near-neutral pH, which may have important implications for nitrate-contaminated site remediation.

Identification of Key Genes in Nasopharyngeal Carcinoma Based on Bioinformatics Analysis.

Objective: This study aimed to identify key genes associated with the pathogenesis of nasopharyngeal carcinoma (NPC) by bioinformatics analysis. Methods: Datasets (GSE13597 and GSE34573) were screened and downloaded from the comprehensive gene expression database (GEO). GEO2R online tool was adopted to analyze microarray data GSE13597 and GSE34573 related to NPC. Volcano plot was generated using Bioconductor in R software. "Pheatmap" was used to draw heatmaps based on the top 10 regulated genes of GSE13597 and GSE34573. GO and KEGG analyses were conducted via online tool DAVID. We uploaded the DEGs of NPC to STRING software and then used Cytoscape software to draw PPI network of DEGs. Results: 216 DEGs were obtained in GSE13597 between patient and control group (111 up-regulated DEGs and 105 down-regulated DEGs). 1101 DEGs were obtained in GSE34573 (470 up-regulated DEGs and 641 down-regulated DEGs). 63 common differential genes were screened named co-DEGs in the two datasets. These DEGs were mainly associated with defense response to bacterium, cell-matrix adhesion, chemokine-mediated signaling pathway, tissue homeostasis, humoral immune response, cilium movement, cilium organization, cilium assembly, and epithelial cilium movement. KEGG pathway enrichment analysis showed that DEGs were mainly involved in viral protein interaction with cytokine and cytokine receptor, salivary secretion, p53 signaling pathway, IL-17 signaling pathway, cell cycle, PI3K-Akt signaling pathway, and ECM-receptor interaction. We identified seven hub genes, including FN1, MMP-10, MUC1, KIF23, CDK1, MUC5B, and MUC5AC. Conclusions: Seven hub genes, including FN1, MMP-10, MUC1, KIF23, CDK1, MUC5B, and MUC5AC, might be therapeutic potential biomarkers of NPC.

Risk Factors for the Onset of Frozen Shoulder in Middle-Aged and Elderly Subjects Within 1 Year of Discharge From a Hospitalization That Involved Intravenous Infusion: A Prospective Cohort Study.

Aim: To investigate the incidence of frozen shoulder and risk factors for the onset of frozen shoulder in middle-aged and elderly subjects within 1 year of discharge from a hospitalization that involved intravenous infusion in Zhangjiagang Second People's Hospital. Methods: A total of 1,900 subjects who were discharged from a hospitalization that involved intravenous infusion in the hospital between May 2020 and September 2020 met the inclusion criteria for this study: 950 subjects had a mean daily duration of intravenous infusion ≤ 2 h (low exposure) and 950 subjects had a mean daily duration of intravenous infusion ≥3 h (high exposure). Subjects were followed up by telephone at 6 months ± 1 week and 12 months ± 1 week after discharge the incidence of frozen shoulder. Results: The cumulative incidence rate of frozen shoulder within 1 year of discharge was 5.2%. Multivariate logistic regression analysis revealed the risk of frozen shoulder was higher in subjects with a mean daily duration of intravenous infusion ≥3 h compared to ≤ 2 h (OR = 3.082, 95% CI 1.919-4.949, P < 0.001); subjects hospitalized for 11-30 days had a higher risk of frozen shoulder compared to those hospitalized for 10 days or less (OR = 6.836, 95%CI 4.363-10.709, P < 0.001); subjects who were overweight/ obese (BMI ≥ 25 kg/m2) had a higher risk of frozen shoulder compared to those of normal weight (BMI 18.5-24.9 kg/m2) (OR = 2.166, 95%CI 1.376-3.410, P = 0.001); subjects in the 56-70-year-old age group had a higher risk of developing frozen shoulder compared to those in the 40-55-year-old age group (OR = 1.977, 95%CI 1.154-3.387, P = 0.013); diabetes increased the risk of frozen shoulder (OR = 3.009, 95%CI 1.826-4.959, P < 0.001). The 71-85 years old age group and hypertension were statistically significant in univariate analysis but not in multivariate analysis (P > 0.05). Conclusion: Compared with middle-aged and elderly in the general population, middle-aged and elderly subjects who received intravenous infusion during a hospitalization had a higher cumulative incidence rate of frozen shoulder within 1 year after discharge. Independent risk factors for the onset of frozen shoulder included mean daily duration of intravenous infusion ≥3 h, length of hospital stay 11-30 days, BMI ≥ 25 kg/m2, age 56-70 years, and diabetes.

Effects of CIK Cell Therapy Combined with Camrelizumab on the Quality of Life in Patients with Nasopharyngeal Carcinoma and Analysis of Prognostic Factors.

Objective: To investigate the effects of CIK (cytokine-induced killer) cell therapy combined with camrelizumab on the quality of life in patients with nasopharyngeal carcinoma and prognostic factors. Methods: In this retrospective study, the materials of 80 patients with nasopharyngeal carcinoma treated in our hospital (February 2017-February 2019) were retrospectively analyzed, and they were equalized into experimental group (n = 40) and control group (n = 40) according to the order of admission. Both groups received 200 mg of camrelizumab on day 1 combined with 10 mg of anrotinib from day 2 to day 4. The patients received the above program every 3 weeks and 4 treatment cycles. The experimental group also received CIK cell therapy simultaneously. The patients' quality of life, immune indexes, local control, metastasis, and survival rate were compared between the two groups, and the prognostic factors were analyzed by logistic analysis. Results: Compared with the control group, the experimental group achieved much higher scores of physical well-being (18.38 ± 2.31), social/family well-being (16.40 ± 2.24), emotional well-being (15.35 ± 2.30), functional well-being (17.30 ± 2.20), and head and neck cancer subscale (15.40 ± 2.01, P < 0.001) and eminently better immune indexes (P < 0.001) after treatment. During the 24-month follow-up, there were 2 recurrent cases (5.0%) and 2 cases (5.0%) with distant metastasis among the 40 patients in the experimental group; there were 8 recurrent cases (20.0%) and 7 cases (17.5%) with distant metastasis among the 40 patients in the control group. In the experimental group, the median survival period was 18 months and the 2-year survival rate was 97.5% (39/40). In the control group, the median survival period was 14 months and the 2-year survival rate was 85.0% (34/40). Among the 80 patients, 7 cases (8.75%) died and 73 cases (91.25%) survived. After conducting the single-factor analysis, remarkable differences in the cases of IV stage, quality of life after treatment, and immune indexes after treatment between the survival group and the death group were observed (P < 0.05). According to the multiple-factor analysis, the clinical stage and immune indexes were identified as the prognostic factors. Conclusion: CIK cell therapy combined with camrelizumab can enhance the life quality and immune function of the patients with nasopharyngeal carcinoma, thus improving their prognoses.

Congenital anterior polar cataract associated with a missense mutation in the human alpha crystallin gene CRYAA.

PURPOSE: To identify the potential pathogenic mutation over four generations of a Chinese family with congenital anterior polar cataracts (APC). METHODS: We investigated four generations of a Chinese family who are afflicted with anterior polar cataracts. The family resides in a relatively isolated region of Northern China. Peripheral blood samples were collected from all of the family members, and genomic DNA was then extracted from the blood samples. A gene scan was performed using about 400 primers labeled with fluorescent stain. Linkage software defined the region of the diseased gene with a Linkage analysis, and Cyrillic software processed the resulting haplotypes. Mutation detection was performed in the candidate gene by sequencing amplified products. RESULTS: A maximum logarithm of odds score (LOD) score was obtained at marker D21S1252(LOD score [Z]=3.23, recombination fraction [θ]=0.0. Haplotype analysis traced the disease gene to an 18.47 cM region bounded by D21S263 and D21S266 on chromosome21q22.11-q22.3. Direct sequencing of the candidate alpha A crystallin (CRYAA) gene revealed a c.347G>A transition in exon 3 of CRYAA that co-segregated with the cataract in the family members and was not observed in 100 control patients. This single-nucleotide change resulted in the substitution of a highly conserved Arginine by Histidine (R116H). CONCLUSIONS: The present study identified a missense mutation (R116H) in the CRYAA gene that causes autosomal dominant congenital anterior polar cataracts in a Chinese family. Our finding confirms the high rate of apparently independent mutations at this dinucleotide.

Batch Transfer Printing of Small-Size Silicon Nano-Films with Flat Stamp.

Silicon nano-film is essential for the rapidly developing fields of nanoscience and flexible electronics, due to its compatibility with the CMOS process. Viscoelastic PDMS material can adhere to Si, SiO2, and other materials via intermolecular force and play a key role in flexible electronic devices. Researchers have studied many methods of transfer printing silicon nano-films based on PDMS stamps with pyramid microstructures. However, only large-scale transfer printing processes of silicon nano-films with line widths above 20 µm have been reported, mainly because the distribution of pyramid microstructures proposes a request on the size of silicon nano-films. In this paper, The PDMS base to the curing agent ratio affects the adhesion to silicon and enables the transfer, without the need for secondary alignment photolithography, and a flat stamp has been used during the transfer printing, with no requirement for the attaching pressure and detaching speed. Transfer printing of 20 µm wide structures has been realized, while the success rate is 99.3%. The progress is promising in the development of miniature flexible sensors, especially flexible hydrophone.

Design and Simulation of Flexible Underwater Acoustic Sensor Based on 3D Buckling Structure.

The exploration of marine resources has become an essential part of the development of marine strategies of various countries. MEMS vector hydrophone has great application value in the exploration of marine resources. However, existing MEMS vector hydrophones have a narrow frequency bandwidth and are based on rigid substrates, which are not easy to be bent in the array of underwater robots. This paper introduces a new type of flexible buckling crossbeam-cilium flexible MEMS vector hydrophone, arranged on a curved surface by a flexible substrate. A hydrophone model in the fluid domain was established by COMSOL Multiphysics software. A flexible hydrophone with a bandwidth of 20~4992 Hz, a sensitivity of -193.7 dB, excellent "8" character directivity, and a depth of concave point of 41.5 dB was obtained through structured data optimization. This study plays a guiding role in the manufacture and application of flexible hydrophones and sheds light on a new way of marine exploration.

A new locus for autosomal dominant congenital coronary cataract in a Chinese family maps to chromosome 3q.

PURPOSE: To identify the genetic defect in an autosomal dominant congenital coronary cataract family (ADCCC). METHODS: A Chinese family with ADCC was identified and characterized. All the members were genotyped with microsatellite markers at genes and loci that were considered to be associated with hereditary cataracts. Linkage analysis was performed after genotyping. Two-point Logarithm of odds (LOD) scores were calculated using MLINK software, from the LINKAGE program package. Multipoint parametric and non-parametric linkage were performed via the program MERLIN. RESULTS: Linkage analysis provided evidence for a genetic locus for the ADCC on chromosome 3q. The maximum Two-point LOD score was 3.01 (theta=0) for two close markers. CONCLUSIONS: The mapping of the congenital cataracts in a Chinese family locus to chromosome 3q.
