In order to improve the degradability and biocompatibility of sodium alginate (SA), SA was oxidized with sodium periodate and then grafted with cell adhesion peptide by carbodiimide water method. Modified sodium alginate (ROSA) was used as the material to prepare monodispersible water-in-oil droplets by the shear action of continuous relatively dispersed phase in microfluidic technology. After the release of calcium ions in the droplets, the droplets were crosslinked into homogeneous hydrogel microspheres. The structural of SA before and after modification were detected by infrared spectroscopy (FT-IR) and X-ray photoelectron spectroscopy (XPS). The surface morphology and biocompatibility of the microspheres were characterized by inverted optical microscopy and laser confocal microscopy. The most suitable hydrogel microspheres for subsequent biomedical applications were obtained by systematically studying the effect of the fabrication technique on the microsphere properties, and adjusting the flow rates of the dispersed and continuum phases, the degree of oxidation and the mass fraction of the SA. Results showed that the formation of aldehyde group and the detection of nitrogen in ROSA proved the success of the SA material modification. The size of the hydrogel microspheres could be controlled at (50.4 ± 1.3) μm, the coefficient of variation was less than 5%, the monodispersion was good, and the structure shape was regular. The microspheres were completely degraded within 4 weeks in vitro and could effectively control the release of the loaded recombinant human bone morphogenetic protein-2 (rhBMP-2). The microspheres showed no obvious cytotoxicity to rat bone marrow mesenchymal stem cells (rBMSCs), and their adhesion to rBMSCs was significantly enhanced, showing good biocompatibility.

As one of the low carbon emission resource technologies, anaerobic digestion technology still faces the challenges of low methane production, unstable system operation, and residue refractory pollutants. Biochar had been widely concerned in the application of improving anaerobic digestion due to its excellent characteristics. In this study, CiteSpace software was used to conduct a quantitative analysis of the research trends of biochar application in the field of anaerobic digestion, and to explore the research status, hot spots and development trends in this field. The results showed that from 2010 to 2022, the number of papers published on the application of biochar in the field of anaerobic digestion kept increasing year by year, and China and the United States were the countries with the largest number of papers. The effects of the physical and chemical properties of different biochar on its application in anaerobic digestion, the mechanisms of improving the efficiency of anaerobic digestion by biochar, and the removal of pollutants such as heavy metals, polycyclic aromatic hydrocarbons and resistant genes by biochar in anaerobic digestion have gradually become hot spots. The research frontiers in this field include quantifying the contribution of different mechanisms of biochar in anaerobic digestion, further developing modification methods to improve the removal of refractory pollutants (heavy metals, polycyclic aromatic hydrocarbons, antibiotics, resistant genes, microplastics, etc.) during anaerobic digestion.

In order to verify whether the cryptochrome protein IgCRYl of Isochrysis galbana interacted with the downstream protein IgCOPl, the total RNA of Isochrysis galbana was extracted and reverse transcribed into cDNA as a template to amplify the target fragment. The BE)-IgCRYl and AD-IgCOPl vectors were constructed and co-transfected into the yeast, strain AH109 for the yeast two-hybrid verification. And the bioinformatics analysis of IgCOPl protein was performed. The results showed that the CDS sequences of IgCRYl and IgCOPl cloned from Isochrysis galbana were 1 560 bp and 1185 bp, respectively. The mutual interaction between IgCRYl protein and IgCOPl protein was verified by the yeast two--hybrid system. The bioinformatics analysis of the interacting protein IgCOPl revealed that the molecular size of the protein was 43. 7 kDa, and the number of encoded amino acids was 394, which was a typical hydrophilic protein with 62. 69% of its secondary structure irregularly coiled. The phylogenetic tree analysis showed that IgCOPl protein was clustered at the bottom of the branch, and had a distant relationship with the other branches. The verification of the interactions between IgCRYl protein and IgCOPl protein provided an important theoretical basis for the biological process of light signal regulation in Isochrysis galbana.

Covalent organic frameworks (COF) is crystalline organic polymers with periodic architectures and well-defined pores, enabling various applications such as gas storage and separation, catalysis, sensor and energy storage. Crystallinity and porosity are two important properties that determine the performance of COF, and the preparation of COF with high crystallinity and specific surface area has been a key issue in the synthesis of COF. Herein, a novel methylated covalent organic framework material (COF-946) was constructed using 2,4,6-trimethyl-benzene-1,3,5-tricarbaldehyde and 2,5- dimethyl-p-phenylene diamine as building blocks. The methylation not only significantly enhances the crystallinity and porosity by preventing pore collapse, but also allows COF-946 to be prepared in a variety of solvent systems. The basic structure and properties of COF-946 were characterized using Fourier transform infrared (FT-IR) spectroscopy, powder X-ray diffraction (PXRD), nitrogen adsorption/desorption isotherms, scanning electron microscopy (SEM) and transmission electron microscopy (TEM). Results show that COF-946 with high crystallinity and specific surface area can be prepared in a wide range of solvents and within a short period of time (SBET > 700 m²/g in 0.5 h). In addition, COF-946 has a high iodine vapor adsorption capacity (5.65 g/g) and adsorption rate (0.78 g/(g·h)), and can maintain more than 90% of the original adsorption capacity after five cycles.

BACKGROUND: Femoral neck fractures can be treated with cannulated screws, dynamic hip screws, locking plates, and intramedullary nails. However, there are still high risks of internal fixation failure, femoral neck shortening, varus deformity, femoral head necrosis and nonunion. The femoral neck system is minimally invasive and provides stable rotation resistance with minimal screw cutting and screw withdrawal. OBJECTIVE: To compare early clinical effects of femoral neck system and femoral neck system combined with cannulated screw on femoral neck fracture. METHODS: The data of 42 patients with femoral neck fracture treated in Department of Orthopedics, Baoding First Central Hospital from March 2020 to October 2021 were retrospectively analyzed. Of them, 33 patients were followed up and divided into femoral neck system group (group A; n=26) and femoral neck system combined with cannulated screw group (group B; n=7). Operation time, intraoperative fluoroscopy times, intraoperative blood loss, length of hospital stay, fracture healing time, curative effect (Harris score) and complications at the last follow-up were recorded. RESULTS AND CONCLUSION: (1) Thirty-three patients were followed up for 3-19 months. (2) Operation time, intraoperative fluoroscopy times, and intraoperative blood loss were significantly less in group A than those in group B (P < 0.05). Length of hospital stay and Harris score postoperatively and at final follow-up were not significantly different (P > 0.05). Hip function was evaluated as follows: excellent in 15 cases, good in 9 cases, and average in 2 cases in group A; excellent in 6 cases and good in 1 case in group B. (3) Postoperative X-ray films showed that all fractures healed, and the healing time was 3-6 months, with an average of 4.5 months. (4) There was no significant difference in the degree of femoral neck shortening between the two groups after operation and at the final follow-up (P > 0.05). (5) None of the patients had complications such as infection and loosening of internal fixation during follow-up. (6) The treatment of femoral neck fractures with femoral neck system or combined with cannulated screw fixation is simple and minimally invasive with satisfactory short-term results.

Objectives: The 2008 Wenchuan Ms 8.0 earthquake triggered tens of thousands of landslides and produced about 10 billion cubic meters of loose material, resulted in a significant increase in the scale and frequency of landslides after the earthquake. The temporal and spatial evolution of post-earthquake landsliding has become the focus of attention of scholars and the public. The Mianyuan River basin is selected as a case study, and the temporal and spatial evolution trend of post-earthquake landsliding is quantitatively analyzed using multi-temporal satellite images. Methods: Firstly, the satellite images of Landsat 7, SPOT-5, Rapid Eye and Planet from 2007 to 2018 are collected and preprocessed such as atmospheric correction, ortho-rectification and image cutting, etc. Then, the maximum likelihood method and the random forest algorithm are engaged to automatically detect the landsliding in the Mianyuan River basin using the preprocessed satellite images. Finally, the landslide detection accuracy of the two methods is evaluated by comparing the landslides interpreted manually and the landslides detected automatically. Results: The average recognition accuracy of random forest algorithm is 86.73%, while the average recognition accuracy of maximum likelihood method is 73.11%. The total area of new landslides detected by the random forest algorithm in 2007, 2008, 2011, 2013, 2015, 2016, 2017 and 2018 are 0.24, 51.54, 19.25, 7.21, 6.39, 7.35, 3.51, 3.82 km2, respectively. Conclusions: The random forest algorithm method has higher detection accuracy than the maximum likelihood method. The landsliding activity in the study area during the 10 years after the Wenchuan earthquake can be divided into three stages: 2008 to 2011 is the strong activity period, the scale and frequency of landsliding activity are significantly increased than before the earthquake, and the disaster losses are serious; 2012 to 2016 is the moderate activity period, the scale and frequency of landsliding activity gradually decreased, and disaster events occurred occasionally; 2017 to 2018 is the weak activity period, the scale and frequency of landsliding activity decreased significantly. After 2017, disaster events rarely occurred in the study area, but landsliding activity still did not return to the pre-earthquake level. [ABSTRACT FROM AUTHOR]

Objective To study the epidemiological situation of inconsistent twin growth and smaller gestational age ( SGA). Methods A retrospective analysis of the clinical characteristics of 147 twins born in the hospital from January 2017 to December 2018 was performed to evaluate the inconsistent twin growth and the incidence of SGA and related factors. Results There were 23 pairs (15. 65%) of inconsistent twin growth, which were included in the group of inconsistent twin growth. There was no significant difference in single chorion and double chorion in the twin growth uniform group (124 cases,84.35%) and the twin growth inconsistent group (P >0. 05). The probability of inconsistent twin growth was increased in older pregnant women, and the difference was not statistically significant( P = 0.102). Hypertensive disorders of pregnancy and abnormal placenta were high risk factors for inconsistent twin growth. Inconsistent twin growth was associated with a weak positive correlation with twin hematocrit (r² = 0.103, P=0.000). Judging according to different gestational age weight percentile standards for twins, SGA were 40 cases (13.61%). Small fetuses with inconsistent twin growth had a higher risk of SGA after birth. Conclusion Inconsistent twin growth requires clinical attention, and the probability of SGA related adverse outcomes in small fetuses increases. It is recommended to select different gestational age weight percentile maps suitable for twins for clinical health care. [ABSTRACT FROM AUTHOR]
