RESUMO
The development of deep geotechnical engineering is restricted by the complex geological conditions of deep rock masses and the unknown creep mechanism of rock in water-rich environments. To study the shear creep deformation law of the anchoring rock mass under different water content conditions, marble was used as the bedrock to make anchoring specimens, and shear creep tests of the anchoring rock mass under different water contents were carried out. The influence of water content on rock rheological characteristics is explored by analysing the related mechanical properties of the anchorage rock mass. The coupling model of the anchorage rock mass can be obtained by connecting the nonlinear rheological element and the coupling model of the anchorage rock mass in series. Related studies show that (1) shear creep curves of anchorage rock masses under different water contents have typical creep characteristics, including decay, stability and acceleration stages. The creep deformation of the specimens can be improved with increasing moisture content. (2) The long-term strength of the anchorage rock mass shows an opposite change law with increasing water content. The creep rate of the curve increases gradually with increasing water content. The creep rate curve shows a U-shaped change under high stress. (3) The nonlinear rheological element can explain the creep deformation law of rock in the acceleration stage. By connecting the nonlinear rheological element with the coupled model of anchoring rock mass in series, the coupled model of waterârock under water cut conditions can be obtained. The model can be used to study and analyse the whole process of shear creep of an anchored rock mass under different water contents. This study can provide theoretical support for the stability analysis of anchor support tunnel engineering under water cut conditions.

Understanding and prediction of mercury (Hg) phytoavailability in vegetable-soil systems is essential for controlling food chain contamination and safe vegetable production as Hg-contaminated soils pose a serious threat to human health. In this study, four typical Chinese soils (Heilongjiang, Chongqing, Yunnan, and Jilin) with varied physicochemical properties were spiked with HgCl2 to grow sweet pepper (Capsicum annuum L.) in a pot experiment under greenhouse condition. The chemical fractionation revealed a significant decrease in exchangeable Hg, while an increase in organically bound Hg in the rhizosphere soil (RS) compared to bulk soil (BS). This observation strongly highlights the vital role of organic matter on the rhizospheric Hg transformation irrespective of contamination levels and soil properties. Stepwise multiple linear regression (SMLR) analysis between Hg concentration in plants, Hg fractions in RS and BS, and soil properties showed that Hg in plant parts was significantly influenced by soil total Hg (THg) (R2 = 0.90), soil clay (R2 = 0.99), amorphous manganese oxides (amorphous Mn) (R2 = 0.97), amorphous iron oxides (amorphous Fe) (R2 = 0.70), and available Hg (R2 = 0.97) in BS. Nevertheless, in the case of RS, Hg accumulation in plants was affected by soil THg (R2 = 0.99), amorphous Mn (R2 = 0.97), amorphous Fe oxides (R2 = 0.66), soil pH, and organically bound Hg fraction (R2 = 0.96). Among all the evaluated soils (n = 04), metal (mercury) concentration in terms of plant uptake was reported highest in the Jilin soil. Based on SMLR analysis, the results suggested that the phytoavailability of Hg was mainly determined by THg and metal oxides regardless of the rhizospheric effect. These findings facilitate the estimation of Hg phytoavailability and ecological risk that may exist from Hg-contaminated areas where pepper is the dominant vegetable.

Objective:To observe the development of elevated body temperature during surgical correction under different general anesthesias in the pediatric patients with congenital ptosis.Methods:Sixty American Society of Anesthesiologists Physical Status classification Ⅰ pediatric patients with blepharoptosis of both sexes, aged 2-10 yr, undergoing elective surgery for blepharoptosis correction, were divided into total intravenous anesthesia group(TIVA group) and combined intravenous-inhalational anesthesia group(CIIA group) using a random number table method, with 30 cases in each group. Anesthesia was induced with intravenous propofol 1-2 mg/kg, cisatracurium 0.15-0.25 mg/kg and fentanyl 2-3 μg/kg in both groups, and then the patients were endotracheally intubated. Anesthesia was maintained with intravenous infusion of propofol 50-200 μg·kg -1·min -1 and remifentanil 0.2-0.05 μg·kg -1·min -1 in TIVA group and with intravenous infusion of propofol 25-75 μg·kg -1·min -1 and remifentanil 0.2-0.5 μg·kg -1·min -1 and inhalation of 1%-1.5% sevoflurane in CIIA group. After completion of anesthesia induction, the nasopharyngeal temperature was continuously monitored until the end of surgery, and the occurrence of elevation in intraoperative body temperature (≥37.5 ℃) was recorded. Results:The incidence of elevated body temperature was 20% and 40% in TIVA group and CIIA group, respectively. Body temperature ≥39.0 ℃ did not occur in two groups. There was no significant difference in the incidence of elevated body temperature and constituent ratio of degree of elevation in body temperature between the two groups ( P>0.05). Conclusions:When total intravenous anesthesia and combined intravenous-inhalational anesthesia are used in the surgery for blepharoptosis correction in the pediatric patients with congenital ptosis, concurrent mild hypothermia is a non-small probability event, but it is safe to evaluate it in terms of the occurrence of malignant hyperthermia.

RESUMO
Objective:To evaluate the relationship between the mechanism underlying the antidepressant effect of S-ketamine and hippocampal gamma-aminobutyric acid B receptor (GABA BR) in mice. Methods:A total of 54 male C57BL/6(B6) mice, aged 8 weeks, weighing 25-30 g, were used in this study. Forty mice were selected to develop the depression model by chronic social defeat stress. Twenty-six depression-susceptible mice were screened out by social avoidance test at day 11 after developing the model and divided into 2 groups ( n=13 each) by a random number table method: depression-susceptible group (Sus group) and depression-susceptible + S-ketamine group (Sus + S-ket group). The remaining 14 mice served as control group (C group). Starting from day 12 after developing the model, S-ketamine 10 mg/kg was intraperitoneally injected every day for 3 consecutive days in Sus+ S-ket group, while the equal volume of normal saline was given instead in C group and Sus group. The open field test was performed at 1 h after the last administration, and the total distance of movement was recorded. The forced swimming test was performed at 1 day after the open field test, and the immobile time was recorded. The sucrose preference test was performed to calculate the proportion of sucrose consumption at 1 day after the forced swimming test. One hour after the end of behavioral test, mice were sacrificed, and the hippocampal tissues were removed. Western blot was used to detect the expression of GABA BR1, GABA BR2, mammalian target of rapamycin (mTOR), phosphorylated mTOR (p-mTOR), brain-derived neurotrophic factor (BDNF), tyrosine kinase receptor B (TrkB), phosphorylated TrkB (p-TrkB), glutamate receptor 1 (GluR1) and postsynaptic dense protein 95 (PSD95). The p-mTOR/mTOR ratio and p-TrkB/TrkB ratio were calculated. The fluorescence intensity of BDNF in hippocampal CA1 region was detected by immunofluorescence. The number of dendritic spines in hippocampal CA1 region was measured by Golgi staining. Results:In the open field test, no statistically significant difference in the total distance was detected among the three groups ( P>0.05). Compared with C group, the immobile time in the forced swimming test was significantly prolonged, the proportion of sucrose consumption was decreased, the expression of hippocampal GABA BR1, GABA BR2, BDNF, GluR1 and PSD95 was down-regulated, and the ratios of p-mTOR/mTOR and p-TrkB/TrkB were decreased, the fluorescence intensity of BDNF and total number of dendritic spines in the hippocampal CA1 region were decreased in Sus group ( P<0.05), and no significant change was found in the parameters mentioned above in Sus+ S-ket group ( P>0.05). Compared with Sus group, the immobile time in the forced swimming test was significantly shortened, the proportion of sucrose consumption was increased, the expression of hippocampal GABA BR1, GABA BR2, BDNF, GluR1 and PSD95 was up-regulated, the ratios of p-mTOR/mTOR and p-TrkB/TrkB were increased, and the fluorescence intensity of BDNF and total number of dendritic spines in the hippocampal CA1 region were increased in Sus+ S-ket group ( P<0.05). Conclusions:The mechanism underlying the antidepressant effect of S-ketamine may be related to up-regulation of hippocampal GABA BR expression, activation of mTOR-BDNF signaling pathway, and improvement in synaptic plasticity in mice.

A combination of alfentanil 10 μg/kg and remimazolam 0.2 mg/kg was intravenously injected until loss of consciousness in group R. Remifentanil 0.5 μg/kg combined with propofol 1.0-2.0 mg/kg was intravenously injected until loss of consciousness in group P. According to the intraoperative conditions, 1/4 of the initial dose of remimazolam was intravenously injected in group R, and 1/4 of the initial dose of propofol was intravenously injected in group P. The time for gastroscopy, requirement for additional remimazolam or propofol, onset time of anesthesia, emergence time and time of post-anesthesia care unit stay were recorded.Physician′s satisfaction scores, patient′s satisfaction scores and Verbal Pain Scale scores were recorded.The occurrence of injection pain, respiratory depression, bradycardia, hypotension and nausea and vomit was recorded. Results:There was no significant difference in the requirement for additional remimazolam or propofol, onset time of anesthesia, time for gastroscopy, physician′s satisfaction scores, and patient′s satisfaction scores, Verbal Pain Scale scores and incidence of nausea and vomit between two groups ( P>0.05). Compared with P group, the emergence time and time of post-anesthesia care unit stay were significantly shortened, and the incidence of injection pain (0 vs.33%), respiratory depression (0 vs.20%), hypotension (3% vs.23%) and bradycardia (3% vs.23%) was decreased in R group ( P<0.05). Conclusions:Remimazolam combined with alfentanil is safe and effective, with rapid recovery from anesthesia, and provides better efficacy than the combination of propofol and remifentanil when used for gastroscopy in frail elderly patients.
RESUMO
Objective:To evaluate the effects of sugammadex on the quality of recovery after laparoscopic bariatric surgery in severely obese patients.Methods:One hundred and eighty patients, aged 18-65 yr, with body mass index ≥ 40 kg/m 2, undergoing elective laparoscopic bariatric surgery, of American Society of Anesthesiologists physical status Ⅲ, were enrolled and divided into 2 groups ( n=90 each) by the random number table method: sugammadex group (S group) and neostigmine group (N group). Before anesthesia, bilateral T 6 and T 9 paravertebral nerve blocks were performed, and 0.33% ropivacaine 15 ml was injected on each side.When the reappearance of T 2 was monitored under train-of-four (TOF) stimulation after the end of surgery, and sugammadex 2 mg/kg was intravenously injected in S group, and neostigmine 0.04 mg/kg and atropine 0.02 mg/kg were intravenously injected in N group.After the patient was transferred to the general ward, flurbiprofen axetil 50 mg was injected intravenously every 12 h, and oxycodone and flurbiprofen axetil were used for patient-controlled intravenous analgesia at the same time.When the numerical rating scale (NRS) score ≥4 and the analgesic pump was ineffective, bilateral T 7 paravertebral nerve block was performed for rescue analgesia, and 0.33% ropivacaine 15 ml was injected on each side.The postoperative quality of recovery was assessed by the 15-item Quality-of-Recovery scale before operation and at 24 h after operation.The TOF ratio ≥ 0.9 and extubation time were recorded.The SpO 2 at the time of transfer to post-anesthesia care unit (PACU), the lowest SpO 2 and occurrence of SpO 2 < 92% during PACU were recorded.The occurrence of residual muscle relaxation and Ramsay sedation score were recorded at 30 min after entering PACU.The time of PACU stay, time to the first off-bed activity and length of hospital stay were recorded.The cumulative consumption of oxycodone, requirement for rescue analgesia, dizziness, nausea and vomiting, hypoxemia, and pulmonary complications were recorded within 48 h after operation. Results:There were no significant differences in the total score of 15-item Quality-of-Recovery scale before surgery and at 24 h after surgery, cumulative consumption of oxycodone within 48 h after surgery, rate of rescue analgesia, and incidence of dizziness, nausea and vomiting, hypoxemia and pulmonary complications between the two groups ( P>0.05). Compared with N group, the scores of the three recovery indicators (feel energized with enough rest, engagement in work or family activities, and tension and anxiety) were significanatly increased, time to TOF ratio ≥ 0.9, extubation time, time of PACU stay, time to the first off-bed activity and length of hospital stay were shortened, and the incidence of residual muscle relaxation was decreased in S group ( P<0.05). Conclusions:Antagonizing residual muscle relaxation with sugammadex is helpful for the recovery of severely obese patients after laparoscopic bariatric surgery.

RESUMO
Objective:To evaluate the reliability and validity of the Chinese version of concise health status questionnaire (SF-36 scale) in evaluating the quality of life of patients with chronic Keshan disease, and to provide a scientific basis for studying the quality of life and the evaluation of treatment and rehabilitation of this population.Methods:In the August 2017, using cluster random sampling method, 175 patients with chronic Keshan disease treated by self-management of family beds in Pingliang City, Gansu Province in 2017 were selected as survey subjects, and demographic and disease data were collected. The Chinese version of SF-36 scale was used to investigate the quality of life. Split-half reliability and Cronbach's α coefficient were used to evaluate the reliability of the SF-36 scale; the factor analysis, correlation and differences between groups were used to evaluate the validity of the SF-36 scale.Results:The split-half reliability value of SF-36 scale was 0.916, and the Cronbach's α coefficient was 0.869. Factor analysis extracted 3 common factors from 8 dimensions of SF-36 scale, and the cumulative contribution rate of the 3 common factors to the total variance was 72.08%. In addition to the correlation coefficient ( r) between Role-Emotional and Bodily Pain dimension, the r value between total score and the scores of each dimension, and the scores of each dimension of SF-36 scale were 0.140 - 0.769. Except for the Bodily Pain dimension, there were statistically significant differences in the scores of Physiological Functioning, Role-Physical, General Health, Vitality, Social Functioning, Role-Emotional, and Mental Health dimension of the quality of life of patients with different grades of cardiac function ( F = 4.66, 10.73, 6.77, 14.61, 5.58, 9.57, 7.10, P < 0.05). Conclusion:The Chinese version of SF-36 scale has good reliability and validity in evaluating the quality of life of patients with chronic Keshan disease, and can be used to evaluate the quality of life of the patients.
RESUMO
Objective:To evaluate the optimization efficacy of low-dose esketamine combined with propofol in the patients with major depressive disorder undergoing modified electroconvulsive therapy (MECT).Methods:Fifty-six American Society of Anesthesiologists physical statusⅠor Ⅱ patients, aged 18-64 yr, scheduled for MECT for the first time, were assigned into esketamine plus propofol group (group EP, n=28) and propofol group (group P, n=28) according to a ratio of 1∶1 by the random number table method.Esketamine 0.25 mg/kg was intravenously injected before anesthesia induction in group EP, while the equal volume of normal saline was given instead in group P. Propofol and succinylcholine were then intravenously injected to perform MECT in two groups.The primary outcomes were the remission rate and response rate, and the secondary outcomes included the number of MECT required for response and remission, the seizure duration, energy inhibition index and consumption of propofol for each MECT, and the occurrence of therapy-related adverse reactions and relapse. Results:Compared with group P, the remission rate and response rate were significantly increased, and the number of MECT required for response and remission was decreased, the seizure duration was prolonged, and energy inhibition index was increased, the consumption of propofol was reduced ( P<0.05), and no significant change was found in the incidence of therapy-related adverse reactions and relapse in group EP ( P>0.05). Conclusions:Low-dose esketamine combined with propofol can enhance the efficacy of MECT and shorten the course of therapy without increasing therapy-related adverse reactions in the patients with major depression.
RESUMO
Objective:To compare the efficacy of mivacurium versus cisatracurium in patients undergoing painless fiberoptic bronchoscopy.Methods:A total of 100 patients of both sexes, aged 18-64 yr, of American Society of Anesthesiology physical status I or Ⅱ, scheduled for elective fiberoptic bronchoscopy were divided into 2 groups ( n=50 each) using a random number table method: mivacurium group (M group) and cisatracurium group (C group). Mivacurium 0.15 mg/kg was injected intravenously in group M, and cisatracurium 0.1 mg/kg was injected intravenously in group C. The onset time of neuromuscular block (ThD95), the duration of neuromuscular block (TOFR25), recovery index (RI), recovery time of autonomous respiration, extubation time and time of discharge from postanesthesia care unit (PACU) were recorded.The occurrence of intraoperative and postoperative adverse reactions and complications were recorded.The mean arterial pressure (MAP), heart rate (HR) and SpO 2 at restlessness at 10 min after entering the operating room (T 1), at loss of consciousness (T 2), when laryngeal mask airway was inserted (T 3), at the end of surgery (T 4), when laryngel mask airway was removed (T 5), and when the patients left the operating room (T 6). Results:Compared with group C, TOFR25, RI, recovery time of autonomous respiration, extubation time and time of discharge from PACU were significantly shortened, the total incidence of adverse reactions was decreased ( P<0.05), and no significant change was found in ThD95 in group M ( P>0.05). There was no significant difference in MAP, HR and SpO 2 at each time point between the 2 groups ( P>0.05). Conclusion:Mivacurium provides better efficacy than cisatracurium when used for painless fiberoptic bronchoscopy.
