Obejective: To explore the therapeutic effect of pain-alleviating formula combined with moist burn ointment on healing of postoperative anal fistula wounds and its influence on cell growth factors and pain stress. Methods: A total of 116 patients with anal fistula admitted to The First Affiliated Hospital of Hunan University of Traditional Chinese Medicine from May 2020 to June 2022 were divided into control group (58 cases, treated with moist burn ointment) and study group (58 cases, combined with pain-alleviating formula directed drug delivery) by random number table method. After 30 days of treatment, the changes in clinical efficacy, clinical indicators [wound healing rate, visual analogue scale (VAS) score, wound exudate score, wound edema score, granulation growth score], cell growth factors [vascular endothelial growth factor (VEGF), serum epidermal growth factor (EGF), fibroblast growth factor (bFGF)] and pain stress indicators [beta-endorphin (β-EP), substance P (SP)] were compared between the two groups. Results: The clinical total efficiency and wound healing rate of the study group were higher than those of the control group, while the VAS score, wound exudate score, wound edema score, granulation growth score of the study group were lower than those of the control group. The wound healing time of the study group was shorter than that of the control group (P<0.05). After treatment, the serum levels of EGF, VEGF, bFGF in the study group were higher than those in the control group (P<0.05). After treatment, the serum levels of β-EP and SP in the study group were lower than those in the control group (P<0.05). Conclusion: Pain-alleviating formula combined with moist burn ointment can promote wound healing after anal fistula surgery, which may be related to regulating serum cell growth factors and reducing pain stress.

The severe environmental problems caused by electrolytic manganese residue（EMR） have aroused extensive concern of scholars at home and abroad, and it is urgent to treat EMR harmlessly. Magnesium phosphate cement（MPC） was used as curing agent to stabilize EMR. The variation of compressive strength of MPC-EMR solidified body with different MPC content and different ages was studied; the curing efficiency of MPC for heavy metals and ammonia nitrogen in EMR was investigated; XRD,SEM and EDS were used to compare and analyze the phase composition and micro morphology of the cured body; at the same time, the internal mechanism of pollutants in MPC stabilized EMR was discussed. The results show that the compressive strength of the solidified body with 5%～15% MPC content is positively related to the MPC content, while the change rule of the compressive strength of the solidified body with 15%～60% MPC content is not obvious; at 15% MPC dosage, the compressive strength of the solidified body at 3,7,28 d and 56 d is 0.51,0.9,8.5,10.92 MPa respectively. The leaching concentrations of Mn2+ and NH+4-N in the raw slag are 1 220 mg/L and 140 mg/L respectively, which are 610 times and 9.3 times of the Class I discharge standard in the Integrated Wastewater Discharge Standard（GB 8978--1996）. The curing efficiency of Mn2+ and NH+4-N in the 28 d curing body can be as high as 99.98% and 98.68% with the addition of 5% MPC.After MPC curing, the soluble Mn2+ in EMR is finally stabilized and solidified with insoluble compounds such as Mn（OH）2,Mn3（PO4）2·3H2O,and then further consolidated by adsorption of struvite gel or encapsulation of crystal structure network; NH+4-N is mainly solidified by struvite crystal（NH4MgPO4·6H2O）.Under alkaline environment, part of NH+4-N will be converted into NH3 and escape.

This paper presents a green and simple redox strategy based on Fe2+, which is used for improving the moisture resistance of fluoride red phosphors. Fluorescent material K2SiF6:Mn4+ were synthesized by coprecipitation method, and the corresponding morphology, crystal component, elemental composition, photoluminescence properties, fluorescence lifetime, water resistance and thermal stability of samples before and after Fe2+ treatment were investigated. The scan electron microscope (SEM) test predicted that after Fe2+ ion treatment, the aggregation of K2SiF6:Mn4+ (T-KSFM) particles was effectively inhibited. The X-ray photoelectron spectroscopy (XPS) indicated that the diminution of Mn was evident on T-KSFM's particle surface after treatment. Spectral test results show that the strongest excitation peak was at about 468 nm, the second strongest peak was at about 360 nm, and the strongest narrowband emission peak was at 632 nm. After the Fe2+ treatment, T-KSFM phosphor was soaked in deionized water for 320 min. Its relative luminescence intensity was 80.3% of the initial luminescence intensity, while that of KSFM was only 63.4%. In addition, the color coordinates of WLEDs made by packaging T-KSFM as the red component, yellow powder YAG and blue chip packaging were (0.4110, 0.3963), which were in the warm white light region. The above results show that this simple redox strategy based on Fe2+ can improve the moisture resistance of fluoride red phosphors effectively, which provided novel ideas to obtaining fluoride phosphors that possess excellent moisture resistance.

Objective: To investigate the effects of percutaneous vertebroplasty on the biomechanics of patients with osteoporotic thoracolumbar fractures. Methods: A total of 9 frozen fresh cadavers of the thoracolumbar spine were selected for this research and randomly divided into observation group(n=3), control group 1(n=3) and control group 2(n=3). The observation group and the control group 1 were made into osteoporotic thoracolumbar fracture models; the observation group was injected with low viscosity bone cement with contrast medium, and the control group 1 was treated with pedicle screw fixation; the main biomechanical indexes(maximum compressive strength, stiffness and height) of the two groups were measured before and after operation. The control group 2 was taken as a reference only, measured only once. The detection results of biomechanical indexes of the three groups were statistically analyzed.Results: There were no significant differences in the maximum compressive strength, stiffness and height before operation between the observation group and the control group 1(P0.05). However, the maximum compressive strength and stiffness of the two groups were lower than those of the control group 2, and the height was higher than that of the control group 2(P0.05). After operation, the maximal compressive strength and stiffness of the observation group and the control group 2 were higher than those of the control group 1, and the height was lower than that of the control group 1(P0.05), while there were no significant differences in the maximum compressive strength, stiffness and height after operation between the observation group and the control group 2(P0.05). Conclusion: The application of percutaneous vertebroplasty in the treatment of osteoporotic vertebral fractures can effectively restore the biomechanical properties of patients, and the effects are exact.

异种器官移植是解决供体器官短缺的最适途径。基因工程已很大程度上克服了异种器官移植出现 的超急性排斥反应等早期障碍，但是异种器官的成功存活还需要预防T 细胞介导的急性排斥反应。目前异种器官 移植中预防T 细胞免疫排斥的方案分为3 种：从基因水平进行改造减少T 细胞免疫排斥反应、直接阻断T 细胞 免疫排斥反应、诱导移植受体的免疫耐受能力。在临床应用前，对这些方案进行研究和优化，有望实现异种器官 移植后的长期存活。 [ABSTRACT FROM AUTHOR]
