Objective：To discuss the technological process of platelet rich fibrin (PRF) /hydroxyapatite (HA) complex prepared by the“sandwich”method, and to evaluate its properties. Methods：The injectable PRF (I-PRF) and advanced PRF (A-PRF) were prepared with the centrifugation indexes of 700 r·min－1 × 3 min and 1 300 r·min－1 ×14 min, respectively, then they were combined with HA using the“sandwich” method. The microstructure of PRF/HA complex was observed under scanning electron microscope (SEM) after freeze drying；the material was immersed in the simulated body fluid (SBF), and the growth of a bone-like layer on the surface of HA was observed on the 2nd, 4th, 8th, and 16th days, respectively, and its mineralization ability was evaluated；the PRF/HA complex extract solution co-cultured with preosteoblast MC3T3-E1 cells of the mice and complete culture medium were used as experimental group and control group；after cultured for 1, 3 and 5 d, respectively, the proliferation activities of the preosteoblast MC3T3-E1 cells were evaluated by CCK-8 method. Two full-thickness cranial defect areas with a diameter of 6 mm were symmetrically established on both the sides of the sagittal suture in the Japanese white rabbits；one side implanted with PRF/HA complex was regarded as experimental group, the other side without any material implantion was regarded as control group；X-ray and cone beam CT (CBCT) were used on the surgical area to evaluate the bone formation performance of the rabbits in two groups 4 and 8 weeks after surgery. Results：The PRF/HA complex with a“sandwich”structure was successfully prepared, with the A-PRF on the outside and the I-PRF mixed with HA particles on the inside. The SEM observation results showed that the cross-section of the complex was an obvious threelayer structure, with the dense fibrin net on the outside and the porous HA particles attached by fibrin filaments on the inside. After being immersed in SBF, the mineralized nodules were formed on the surface of HA on the 2nd day, the bone-like layer was gradually established with the prolongation of the immersion time, and a lamellar structure was formed at the 16th day. The cell proliferation experiment results showed that compared with control group, the proliferation activities of the MC3T3-E1 cells in experimental group were significantly increased on the 1st, 3rd, and 5th days (P<0. 05) . The imaging observation results showed that the cranial defect in experimental group had obvious marginal osteogenesis 4 weeks after surgery and the new bone had almost completely filled the bone defect area 8 weeks after surgery, while the new bone formation of the cranial defect in control group was significantly decreased than that in experimental group. Conclusion：PRF/HA complex prepared by the“sandwich”method has a good mineralization ability and biocompatibility, and can promote the bone regeneration. [ABSTRACT FROM AUTHOR]

Video super-resolution(VSR), which aims to exploit information from multiple adjacent frames to generate a highresolution version of a reference frame. Many existing VSR works focus on how to effectively align adjacent frames to better fuse adjacent frame information, and little research has been done on the important step of adjacent frame information fusion. To solve this problem, This paper propose a video super-resolution model based on group feedback fusion mechanism(GFFMVSR). Specifically, after adjacent frames are aligned, the aligned video sequences are fed into the first temporal attention module. Then, the sequence is divided into several groups, and each group achieves preliminary fusion through the intra-group fusion module in turn. Next, the fusion results of different groups go through a second temporal attention module. Then, each group inputs the feedback fusion module group by group, and uses the feedback mechanism to feedback and fuse the information of different groups. Finally, the fusion result output is reconstructed. It has been verified that the model has strong information fusion ability, and is superior to the existing models in both objective evaluation indicators and subjective visual effects.

Land subsidence is a common geological disaster. Tianjin is one of the cities with serious land subsidence in China. The research on the characteristics of land deformation is helpful to understand the distribution of land subsidence and carry out urban planning reasonably. Based on the sentinel-1 orbit raising and descending data covering the Tianjin area, the satellite line of sight（LOS） deformation rate field was obtained by using the improved small baseline timing interferometry method. Aiming at the serious atmospheric impact in coastal areas, the GACOS（generic atmospheric correction online service for InSAR） atmospheric correction model was used to remove the influence of atmospheric error. From the obtained deformation velocity field in Tianjin, it can be seen that the shape variable in Tianjin urban area was relatively small, there was a certain deformation funnel in Jinghai district and Xiqing District around the urban area, and the maximum LOS direction shape variable was about-40 mm/a. Wuqing District and Beichen District had the largest shape variables, and there was a deformation funnel with a large range and shape variable level. The center of the deformation funnel is Wangqingtuo Town, Wuqing district. The maximum LOS direction shape variables in the track lifting and track lowering results are 80 mm/a and 99.2 mm/a respectively. Combined with the land use situation in this area, it is found that it is mainly due to the intensive construction of industrial parks, leading to excessive industrial and domestic water consumption, resulting in overexploitation of groundwater. It can be seen from the deformation results that it is necessary to carry out scientific water management and reasonable urban planning for the areas with a deformation funnel, to effectively improve the impact of regional deformation.

Background and purpose: Adriamycin also named as doxorubicin, is one of the most widely used cytotoxic chemotherapeutic agents for clinical practice for the treatment of various tumors, and belongs to anthracycline antitumor drugs. Unfortunately, this drug will cause serious side effects, especially dose-dependent cardiotoxicity, which has become a concern in the field of onco-cardiology. At present, there is no universally recognized, unified and robust method to construct Doxorubicininduced cardiomyopathy model. This experiment was designed to explore the optimal dose and frequency of doxorubicin-induced cardiomyopathy in a mouse model. Methods: Forty 8-10-week-old male C57BL/6J mice were randomly divided into 4 groups (control group and 3 model groups). The model group was divided into model 1 (M1) group (15 mg/kg, single dose) and M2 group (5 mg/ kg, once a day for 3 days continuously) and M3 group (7.5 mg/kg, twice on alternate days). General vital signs (body weight change and survival rate), echocardiography, body surface electrocardiogram (ECG), N-terminal pro-B-type natriuretic peptide (NT-proBNP), cardiac troponin I (cTnI) and myocardial tissue morphological changes were evaluated comprehensively. Results: Compared with the control group, the body weight of mice in M1, M2 and M3 groups decreased significantly (P＜0.001); M3 group had higher survival rate than M1 and M2 group (80% vs 40% and 50%, P＜0.05). Compared with the control group, M1 group and M2 group, the body surface ECG showed that the PR interval of M3 group [(0.064 2±0.003 8)s vs (0.042 3±0.000 9)s, (0.052  7±0.007  9) s and (0.062  0±0.001  2)s, P＜0.05] and QT interval [(0.047  5±0.000  2)s vs (0.022 0±0.000 9)s, (0.038 6±0.004 4)s and (0.044  4±0.003  0)s, P＜0.05] were significantly prolonged. Cardiac ultrasound showed that M3 ejection fraction decreased significantly (40.40%±2.24% vs 54.72%±1.64%, 46.00%±4.41% and 54.68%±3.38%, P＜0.05). M3 short-axis shortening rate decreased significantly (19.40%±1.20% vs 27.88%±1.05%, 22.57%±2.50% and 27.86%±2.20%, P＜0.05). Cardiac markers showed that compared with CON, the serum NT-proBNP levels of M1, M2 and M3 in adriamycin group were significantly increased [(638.13±12.69) pg/mL vs (1 271.36±11.76) pg/mL, (1 270.85±36.19) pg/mL and (1 225.26±24.19)  pg/ mL, P＜0.05] . Histomorphology showed that the vacuoles in cardiomyocyte of M3 group was significantly increased compared with CON, M1 and M2 group (81/field vs 3/field, 65/field and 34/field, P＜0.05). Conclusion: Intraperitoneal injection of adriamycin in acute heart failure model is simple and reliable. The model in which adriamycin is administered by intraperitoneal injection at a dose of 7.5 mg/ kg, twice on alternate days, with cumulative dose of 15 mg/kg is optimal. [ABSTRACT FROM AUTHOR]

GdTaO4 and LuTaO4 are heavy scintillators with fast decay fluorescence. The photoluminsecence spectra of M phase Nd:GdTaO4 and M′ phase Nd:LuTaO4 excited by a laser diode (LD) of 808 nm were fitted with the full-profile fitting method, and the transition intensity parameters Akt, p were determined. Under the excitation of 808 nm LD laser, the population ratio between the upper and low crystal field energy levels of 4 F3/2 for Nd3+ in GdTaO4 is near to 1, but in LuTaO4 is 1.30 and 1.41, which indicates that the relaxation rate between two crystal field energy levels is nearly equal to the excitation rate of LD. The Judd-Ofelt transition intensity parameters Ωt were calculated with Akt, p, and the transition probabilities from 2 P3/2 of Nd3+ in GdTaO4 and LuTaO4 were computed, which indicates that the fast decay fluorescence of several hundred nanoseconds of Nd3+ in GdTaO4 and LuTaO4 is caused by the high nonradiative transition.

In order to research the environment-friendly and high-efficiency extraction method of platycodin D and lobetyolin from the Platycodon radix, homogenate combined with ultrasonic-microwave synergistic extraction method were used for the first time to extract platycodin D and lobetyolin, and the contents were determined by high performance liquid chromatography (HPLC). Based on the results of single factor experiments, taking ultrasonic-microwave time, microwave power and ethanol volume fraction as the key factors for optimization, and the contents of platycodin D and lobetyolin as the response value, the Box-Behnken response surface methodology was applied to optimize the optimal extraction process, which was compared with Soxhlet extraction and ultrasonic extraction process. The results showed that the best extraction parameters for platycodin D and lobetyolin were homogenate pretreatment for 3 min, ethanol volume fraction of 58%, material-to-liquid ratio of 1 ∶20 g / mL, microwave power of 580 W, extraction time of 15 min and temperature of 50 °C, the predicted values of platycodin D and lobetyolin were 5. 276 mg / g and 0. 249 mg / g, and the measured values were (5. 24±0. 13) mg / g and (0. 24±0. 01) mg / g respectively, which were higher than the content of Soxhlet extraction (4. 72 mg / g± 0. 24 mg / g; 0. 20 mg / g±0. 03 mg / g) and ultrasonic extraction (4. 93 mg / g±0. 15 mg / g; 0. 21 mg / g±0. 02 mg / g). This research confirmed that homogenate combined with ultrasonic-microwave synergistic extraction method can efficiently extract the main active components in Platycodon radix, laying a theoretical foundation for the further development of Platycodon radix.

The experiment was to study the effect of different levels of glucose oxidase (GOD) on growth performance, immune function, serum biochemical indexes and intestinal morphological structure of broilers. A total of 600 healthy one-day-old AA broilers were randomly divided into three groups, with five replicates in each group and 40 in each replicate (half in male and female). The control group was basic diet, and the experimental group Ⅰ and group Ⅱ were supplement with 400 and 1 000 U/kg GOD4000 in basis diet, respectively. The experiment lasted for 42 d. The results showed that compared with the control group, group Ⅰ and test group Ⅱ can significantly increased the average body weight, average daily gain and average daily feed intake of broilers at each stage (P<0.05), and reduced feed to gain ratio (P>0.05). GOD4000 had no significant effect on the immune organ index of broilers (P>0.05). Compared with control group, the serum urea nitrogen content of broilers in group Ⅰ was significantly decreased at the age of 43 d (P<0.05). Compared with control group, the serum total protein content of broilers at 43 d of age in group Ⅱ was significantly increased (P<0.05), and the serum urea nitrogen and total cholesterol levels were significantly decreased (P<0.05). Compared with control group, the jejunal villus height of broilers at 22 and 43 d in group Ⅱ was significantly increased (P<0.05), and the ratio of jejunal villus height to crypt depth at 43 d was significantly increased (P<0.05). The study indicates that GOD4000 can improve the growth performance of broilers, and the effect is enhanced with the increase of the addition level. The addition of 1 000 U/kg GOD4000 to diet can further improve the protein metabolism of broilers and improve the structure of jejunum villi. [ABSTRACT FROM AUTHOR]
