The strength of the backfill body is the key factor to ensure the stability of goafs, so it is necessary to calculate the strength of the backfill body.2 theoretical calculation methods, the Terzaghi model method and the Lupin calculation method, are used to calculate the backfill body strength in Tiaoshuihe Phosphate Mine.To ensure the safety of the mine, the safety factor is taken as 2.0 and the result is 0.76-1.84 MPa.To ensure its accuracy, Flac3D numerical simulation software is used for strength verification and the result is 1.5 MPa, which is within the range of theoretical calculation.The 2 calculation methods are consistent, showing that the calculation of the strength requirement is reasonable.

Objective To compare the effects of isoflurane and pentobarbital on the establishment of subarachnoid block model in rats. Methods 60 SD rats aged 4 months were randomly divided into Group A (n=30) and Group B (n=30). Rats in Group A received intraperitoneal injection of 10g/L pentobarbital sodium solution 30mg/kg and 1/4 of the initial dosage was added according to the operation effect. The induction and maintenance of anesthesia were achieved by isoflurane inhalation in Group B during operation. We recorded the time of anesthesia induction, quality of anesthesia, time of anesthesia, time of operation, and recovery time. The heart rate, respiration frequency, temperature, and saturation of blood oxygen were recorded during operation. We compared death from anesthesia and success of modeling in the two groups. Results There was no significant difference between the groups with regard to age, weight, body temperature or saturation of blood oxygen (P>0.05). Compared to Group B, heart rate decreased 1-60 minutes after anesthesia and respiration frequency decreased 5 minutes after anesthesia in Group A (P<0.05). The time of anesthesia induction, time of anesthesia, time of operation, and recovery time were shorter in Group B (P<0.05). The quality of anesthesia was better in Group B (P<0.05). The success rate of modeling was higher but mortality rate of anesthesia was lower in Group B than in Group A (P<0.05). Conclusion Compared with intraperitoneal injection of pentobarbital sodium, isoflurane inhalation can provide a better anesthetic effect during the operation to establish a rat model of subarachnoid block.

Objective To investigate the effects of dexmedetomidine on the end-tidal concentration of sevoflurane during recovery from breast cancer surgery under general anaesthesia. Methods A total of 120 patients undergoing unilateral breast cancer radical operation were randomly divided into four groups: group C (infusion of saline, n=30), group D0.5 [infusion of dexmedetomidine 0.5 μg/(kg·h) during operation, n=30],group D0.6 [dexmedetomidine 0.6 μg/(kg·h), n=30] and group D0.7 [dexmedetomidine 0.7 μg/(kg·h), n=30]. The end-tidal concentrations of sevoflurane during surgery and postoperation were observed. The end-tidal concentration of sevoflurane on palinesthesia was recorded. The time from stopping administration of anesthetic drug to palinesthesia and the operation time were recorded. The palinesthesia of patients from general anaesthesia and the degree of emergence agitation of the patient were measured using Riker's sedation-agitation scale. The operation time, anesthesia time, intraoperative remifentanil dosage, intraoperative auditory evoked potential index (AAI), sevoflurane inhalation concentration and the corresponding time were recorded. Results There were no significant differences in clinical data, remifentanil dosage, operation time and AAI between four groups. The anesthesia time was longer in group D0.7 than that in the other three groups (P < 0.05). Compared to group C, the end-tidal concentration of sevoflurane during surgery, postoperation and palinesthesia were lower and the time of palinesthesia was delayed in groups D0.5, D0.6 and D0.7 (P < 0.05). And the time of palinesthesia was delayed in group D0.7 than that of group D0.5 and group D0.6. Compared with group C, the ratio of Riker's sedation-agitation scale >7 was lower in groups D0.5, D0.6 and D0.7 (P < 0.05). The ratio of Riker's sedation-agitation scale >4 was significantly higher in group D0.6 and group D0.7 than that in group C and group D0.5, but the ratio of score>6 was lower(P < 0.05). The ratio of score>3 was higher in group D0.7 than that of other three groups (P < 0.05). Intraoperative cardiac tachycardia was found in group D0.6 and group D0.7 (4 cases, 13% and 8 cases, 7%). Conclusion Sevoflurane inhalation anesthesia and intravenous infusion of dexmedetomidine 0.6 μg/(kg·h) can effectively reduce intraoperative sevoflurane dosage, the end-tidal concentration of sevoflurane during recovery, and the occurrence of agitation in patients undergoing general anesthesia.

With improvements in healthcare, the diagnosis and treatment of cardiovascular diseases are becoming more and more specific and detailed. Though it is critical to evaluate large blood vessels of heart, importance of microcirculation accessment is increasingly valued. The concept of index of microcirculatory resistance (IMR) is raised by Dr. Fearon in 2003. IMR is a convenient quantitative evaluation index that can actually reflect microcirculatory resistance, and not influenced by coronary artery stenosis. IMR has the advantage of great reproducibility. This gives IMR a major value in predicting perioperative myocardial infarction, post-PCI microvascular obstruction and prognosis of PCI patients with ST segment elevation myocardial infarction. Meanwhile, It also plays an important role in evaluating auxiliary treatment of PCI, elucidating the pathogenesis of stress-induced cardiomyopathy and evaluating cardiovascular drugs. This review discusses the features of IMR and its clinical applications. [ABSTRACT FROM AUTHOR]

Changes of biological character, yield and N, P, K and Mn content of rape planted on acid yellow soil were studied under different Mn stress to definite the effect of Mn on growing development, yield and nutrient content of rape planted on acid yellow soil. Results: Low Mn stress could stimulate growth of rape, and the height, fresh root weight, fresh weight of aerial part and seed yield of rape under low Mn stress was slightly higher than CK2 (normal application amount of N, P and K). Moderate Mn stress slightly decreases fresh root weight and root length of rape plants but had no obvious effect on height and fresh weight of aerial part. High Mn stress inhibits growth of rape significantly. Duration of seedling stage and budding stage, faint yellow spots appear around the edge of new leaves under moderate Mn stress, and when the edge of new leaves withers and new leaves appear the spoon shape under high Mn stress, Mn content in aerial part of rape reached 1433 mg / kg and fresh root weight, root length, fresh weight of aerial part and seed yield decreases by 15.2 g / plant, 4.67 cm, 16.9g / plant and 3.4 g/pot, respectively. Applying suitable CaCO3 could eliminate Mn toxicity of rape plants cultivated on acid yellow soil. [ABSTRACT FROM AUTHOR]
