ABSTRACT

Objective:To preliminarily investigate the relationship between the mechanism of sevoflurane-induced cerebral neurotoxicity and receptors of 5-HT 1A and 5-HT 3 in aged rats. Methods:Twenty-four clean-grade healthy male Sprague-Dawley rats, aged 18-20 months, weighing 600-750 g, were divided into 3 groups ( n=8 each) using a random number table method: group C, group LS and group HS.In group C, group LS and group HS, 50% O 2, 1.5% sevoflurane plus 50% O 2 and 3% sevoflurane plus 50% O 2 were inhaled for 2 h, respectively.Open field test was performed at 1 day before inhalation of sevoflurane and at 1 day after the end of inhalation, the time spent in the central square, the number of crossing the grid and the number of standing on the back legs were recorded.The Morris water maze test was performed at 6 days before inhalation of sevoflurane and at 1 day after the end of inhalation, the escape latency, the total swimming distance and the number of crossing the platform were recorded.Immediately after the end of behavioral testing, the hippocampal tissues were obtained for determination of 5-HT 1A and 5-HT 3 receptors mRNA expression and the number of positive cells (using real-time reverse transcription-polymerase chain reaction assay and immunohistochemical method). Results:Compared with group C, the time spent in the central square was significantly prolonged, the number of crossing the grid and the number of standing on the back legs were decreased, the escape latency was prolonged, the total swimming distance was increased, the number of crossing platform was decreased, the mRNA expression of 5-HT 1A and 5-HT 3 was down-regulated, and the number of positive cells was decreased in HS group ( P<0.05). Conclusion:The mechanism of cerebral neurotoxicity induced by sevoflurane may be related to the down-regulation of the activities of 5-HT 1A and 5-HT 3 receptors in aged rats.

ABSTRACT

Objective:To investigate the clinical application value of blood oxygen level dependent functional magnetic resonance imaging (BOLD-fMRI) to the protection of language function in patients with unilateral frontal and temporal lobes glioma receiving postoperative intensity modulation radiation therapy (IMRT).Methods:A total of 27 patients with unilateral frontal and temporal lobe gliomas were treated with postoperative radiotherapy. The planning CT and BOLD-fMRI were performed before radiotherapy, and the language functional areas were delineated based on the fused images of 3D T1 and CT. IMRT technology was used to develop radiotherapy plans with and without language function area protection, naming conventional and protective radiotherapy plans respectively. The maximum radiation dose ( Dmax), average radiation dose ( Dmean), target conformal (CI) and dose uniformity (HI) of PTV of the two plans were compared and analyzed to ensure that the protective radiotherapy plan could meet the radiotherapy standard. Then, the Dmax and Dmean of the language function area were compared and analyzed to evaluate whether the Dmax and Dmean of the language function area were decreased in the protective radiotherapy plan. Results:There were no significant differences in CI, HI, Dmax and Dmean of PTV between the conventional radiotherapy plan and protective radiotherapy plan ( P>0.05). There were statistically significant differences in Dmax and Dmean of Wernicke′s and Broca′s (healthy side and affected side) between the conventional radiotherapy plan and protective radiotherapy plan ( t=3.073-12.707, P<0.05). Dmax and Dmean of Wernicke′s and Broca′s (healthy side and affected side) were decreased in the protective radiotherapy plan compared with the conventional radiotherapy plan, and the decrease was significant in the healthy side. Conclusions:BOLD-fMRI combined with IMRT can not only guarantee the target dose of patients with glioma receiving postoperative radiotherapy, but also reduces the radiation dose to the language function area. Chinese reading task and paragraph comprehension task are the stimulation mode of language function in patients after brain tumor surgery. These tasks are simple and the effect is accurate.

ABSTRACT

Objective:To observe the incidence of syncope in patients with acute and critical cardiovascular diseases and to explore the risk factors of death.Methods:925 cases of acute heart failure, acute myocardial infarction, pulmonary embolism, arrhythmia and aortic dissection rupture who participated in Prospective, Multi-CenterRegistered Research Project for Chinese Syncope Patients from March 2018 to March 2020, admitted to the department of emergency of Nanyang Second General Hospital were selected as the research objects. The incidence and mortality of syncope were recorded, and the patients were divided into syncope group and non-syncope group according to whether they were accompanied by syncope or not. The incidence of syncope in male and female patients with different cardiovascular critical diseases, the age and mortality of cardiovascular critical patients with syncope or not were analyzed and compared. Multivariate Logistic regression analysis was used to analyze the risk factors of death, and receiver operating characteristic curve (ROC curve) was drawn to evaluate the predictive value of risk factors on the prognosis of patients.Results:The incidence of syncope in 5 kinds of cardiovascular critical patients from high to low was: acute myocardial infarction 3.03% (28/925), arrhythmia 2.70% (25/925), pulmonary embolism 1.51% (14/925), aortic dissection rupture 1.41% (13/925), acute heart failure 0.65% (6/925), with statistically significant differences ( χ2 = 10.765, P = 0.010). There was no significant difference in the incidence of syncope between male and female patients with pulmonary embolism, aortic dissection rupture, acute myocardial infarction, arrhythmia and acute heart failure. The age of patients with aortic dissection rupture, acute myocardial infarction and arrhythmia in syncope group were significantly higher than those in non-syncope group [aortic dissection rupture (years old): 66.29±15.64 vs. 57.63±14.23, acute myocardial infarction (years old): 69.55±15.13 vs. 62.10±15.75, arrhythmia (years old): 70.48±14.93 vs. 60.29±16.31, all P < 0.05]. The mortality of patients with pulmonary embolism, aortic dissection rupture, acute myocardial infarction, arrhythmia, acute heart failure in syncope group were significantly higher than those in non-syncope group [pulmonary embolism: 5.81% (5/86) vs. 0.95% (8/839), aortic dissection rupture: 4.65% (4/86) vs. 0.60% (5/839), acute myocardial infarction: 4.65% (4/86) vs. 1.19% (10/839), arrhythmia: 2.33% (2/86) vs. 0.95% (8/839), acute heart failure: 2.33% (2/86) vs. 0.60% (5/839), all P < 0.05]. Multivariate Logistic regression analysis showed that age [odds ratio ( OR) = 2.158, 95% confidence interval (95% CI) was 0.921-4.785, P = 0.000], pulmonary embolism ( OR = 15.391, 95% CI was 8.904-27.314, P = 0.001), aortic dissection rupture ( OR = 13.079, 95% CI was 6.237-25.509, P = 0.000), acute myocardial infarction ( OR = 18.826, 95% CI was 10.420-32.921, P = 0.000), syncope ( OR = 4.940, 95% CI was 1.764-9.287, P = 0.000) were risk factors for the prognosis of patients with acute and critical cardiovascular diseases. ROC curve analysis showed that syncope had a certain predictive value for 28-day prognosis of patients [the area under the ROC curve (AUC) = 0.760, P = 0.000], when the cut-off value was 4.12, the sensitivity was 88.51%, the specificity was 78.05%, the positive predictive value was 81.31%, and the negative predictive value was 84.27%. Conclusions:Syncope is an independent risk factor of death in patients with acute and critical cardiovascular diseases. For patients with syncope as the chief complaint, we should quickly identify the types of acute and critical diseases and assess the risk of sudden death.

ABSTRACT

Objective@#To understand knowledge, attitude and behavior toward Coronavirus disease 2019 (COVID 19) among middle school students in Wuhan, in the phase of normalized control and prevention of COVID 19, so as to provide evidence for further health education.@*Methods@#In January 2021, cluster random sampling method was used to select one middle school from Hongshan and Dongxihu District, as well as Donghu high tech zone, respectively. By using the "questionnaire star" platform, questionnaire QR code were sent to students through QQ or wechat by schools. A total of 4 531 middle school students were investigated.@*Results@#Preventive knowledge and behavior rate was 71.5% (3 238) and 56.0% (2 537), respectively. Preventive behaviors towards COVD 19 was reported in 56.0% (2 537) of participants. Students with parents as health care workers reported higher preventive behaviors(P<0.05).Girls had a higher rate of possession of health knowledge for prevention and control than boys. Compared with "essentially no concern about the epidemic","students with less concern about the epidemic" and "those with similar concern as 2020" were more likely to have higher awareness of health knowledge for prevention and control. Compared with the first-year junior middle school students, high school students were less likely to have the rates of knowledge for prevention and control health [OR(95%CI)=1.24(1.09-1.43),2.56(1.54-4.25),3.30(1.99-5.48),0.49(0.39-0.62),0.45(0.36-0.57),0.63(0.46-0.88)].In terms of health behavior rate, middle school students whose mothers are undergraduates, whose incomes were more than 8 001-15 000 and 15 000 yuan, "whose attention to epidemic situation has declined" , "whose attention is the same as that in 2020" , "who did not plan to study medicine before" , "who are determined to study medicine, and who plan to study medicine more firmly after epidemic situation " were more likely to have health behavior,[OR(95%CI)=1.29(1.04-1.60),1.39(1.07-1.82),1.74(1.32-2.29),1.77(1.06-2.96),3.47(2.08-5.81)] ,The grade-2 high middle school students had lower probability of preventing and controlling health behaviors [OR(95%CI)=0.74(0.60-0.90)](P<0.05). Preventive knowledge and behaviors towards COVID 19 are mainly from school education, communication with parents and mobile learning.@*Conclusion@#Preventive knowledge and behaviors towards COVID 19 among Wuhan middle school students are needed to be improved and targeted health education should be implemented accordingly.

Objective@#To explore the effect of high mobility group box-1 protein (HMGB1) on the balance of Th17/Treg in patients with immune thrombocytopenia (ITP).@*Methods@#A total of 30 patients who were first diagnosed as ITP in the Fifth People's Hospital of Datong from July 2017 to April 2018 were selected as the case group, and another 30 healthy volunteers in the corresponding period were taken as the control group. The proportion of Th17 and Treg cells was detected by using flow cytometry, and the concentration of HMGB1, interleukin (IL)-17 and transforming growth factor β (TGF-β) in plasma was tested by using enzyme-linked immunosorbent assay (ELISA). Isolated peripheral blood mononuclear cells (PBMC) were cultured in vitro. After the treatment with recombinant human HMGB1 (rhHMGB1), real-time polymerase chain reaction (RT-PCR) was applied to detect the mRNA expression changes in Treg cell transcription factor intracellular forkhead helix transcription factor 3 (Foxp3) and Th17 cell transcription factor retinoid related orphan receptor γt (RORγt). The differences of indicators in Treg cell transcription factor peripheral blood between the case group and the control group were compared, and the balance correlation between HMGB1 and Th17/Treg was analyzed.@*Results@#Compared with the healthy control group, the proportion of Th17 cells and the expression level of HMGB1 and IL-17 in peripheral blood of ITP patients were increased (all P < 0.01), while the proportion of Treg cells and the level of TGF-β were decreased (all P < 0.01). The proportion of Th17 cells and the expression level of IL-17 and HMGB1 in peripheral blood of ITP patients were positively correlated with the concentration of HMGB1 (all P < 0.01); the proportion of Treg cells and the level of TGF-β were negatively correlated with the expression level of HMGB1 (all P < 0.01). In vitro experiments, the expression of intracellular RORγt mRNA was increased compared with the negative control group (1.50±0.24 vs. 0.93±0.22, t = 9.612, P < 0.01), and the expression of Foxp3 mRNA was decreased compared with the negative control group after the stimulation of PBMC by rhHMGB1 (0.72±0.19 vs. 1.08±0.18, t = 7.387, P < 0.01).@*Conclusion@#The high level of HMGB1 in the peripheral blood of ITP patients induces Th17/Treg imbalance and aggravates inflammatory reactions, which may be an important cause of ITP.

ABSTRACT

Objective:To investigate the application of magnetic resonance imaging (MRI) in clinical staging and classification of adult Japanese encephalitis.Methods:The clinical data and craniocerebral MRI findings of 35 adult patients with Japanese encephalitis admitted in General Hospital of Ningxia Medical University from August to September 2018 were analyzed retrospectively. The MRI imaging characteristics were compared among patients with different stages and types, the apparent diffusion coefficient (ADC value) of thalamic lesions in patients of different stages was analyzed. SPSS 23.0 software was used to analyze the data.Results:Six moderate cases all had lesions involving the thalamus, and the number of intracranial lesions was <2. In 11 severe cases, 8 had lesions involving thalamus and 5 had lesions involving hippocampus; the number of intracranial lesions was <2 in 3 cases, the number of intracranial lesions was 2-4 in 3 cases, and the number of intracranial lesions was >4 in 5 cases. In 18 cases critical cases, the lesions involved thalamic in 14 cases, hippocampus in 14 cases, cerebral cortex in 14 cases, cerebral feet in 9 cases, basal ganglia area in 6 cases, and brain stem in 2 cases, respectively; 2 cases had the intracranial lesions <2, 6 cases had intracranial lesions 2-4, 10 cases had intracranial lesions >4. In 11 preliminary stage patients, 9 cases had DWI high signal and 2 had FLAIR slightly high signal; in 19 extreme stage patients, 16 cases had DWI high signal, 11 cases had FLAIR slightly high signal, 3 cases had T1WI high signal and 6 cases had T2WI high signal. In 5 recovery stage patients, 1 case had DWI slightly high signal, 5 cases had FLAIR high signal, and 1 case had T2WI high signal. The ADC values of thalamic lesions in recovery and extreme patients were higher than those in the preliminary stage ( q=3.931 and 4.012, P<0.05). The ADC value of thalamic lesions in the recovery period was higher than that in the extreme period ( q=3.372, P<0.05). Conclusions:The number of lesions and the range of involvement are associated with disease severity in adult Japanese encephalitis. The DWI sequence is easy to detect at early stage, and the FLAIR sequence shows a long time span of lesions; and the DWI and FLAIR sequences are of great significance for the early clinical staging and classification of adult encephalitis patients. At the same time, the ADC value shows a trend of disease progresses, which can be used as a supplement for the clinical staging in adult encephalitis patients.

ABSTRACT

Objective:To compare the efficacy of the combination of abidol, lopinavir/ritonavir plus recombinant interferon α-2b (rIFNα-2b) and the combination of lopinavir/ritonavir plus rIFNα-2b for patients with COVID-19 in Zhejiang province.Methods:A multicenter prospective study was carried out to compare the efficacy of triple combination antiviral therapy and dual combination antiviral therapy in 15 medical institutions of Zhejiang province during January 22 to February 16, 2020. All patients were treated with rIFNα-2b (5 million U, 2 times/d) aerosol inhalation, in addition 196 patients were treated with abidol (200 mg, 3 times/d) + lopinavir/ritonavir (2 tablets, 1 time/12 h) (triple combination group) and 41 patients were treated with lopinavir/ritonavir (2 tablets, 1 time/12 h) (dual combination group). The patients who received triple combination antiviral therapy were further divided into three subgroups: <48 h, 3-5 d and >5 d according the time from the symptom onset to medication starting. The therapeutic efficacy was compared between triple combination group and dual combination group, and compared among 3 subgroups of patients receiving triple combination antiviral therapy. SPSS 17.0 software was used to analyze the data.Results:The virus nucleic acid-negative conversion time in respiratory tract specimens was (12.2±4.7) d in the triple combination group, which was shorter than that in the dual combination group [(15.0±5.0) d] ( t=6.159, P<0.01). The length of hospital stay in the triple combination group [12.0 (9.0, 17.0) d] was also shorter than that in the dual combination group [15.0 (10.0, 18.0) d] ( H=2.073, P<0.05). Compared with the antiviral treatment which was started within after the symptom onset of in the triple combination group, the time from the symptom onset to the viral negative conversion was 13.0 (10.0, 17.0), 17.0 (13.0, 22.0) and 21.0 (18.0, 24.0) d in subgroups of 48 h, 3-5 d and >5 d, respectively ( Z=32.983, P<0.01), while the time from antiviral therapy to viral negative conversion was (11.8±3.9), (13.5±5.1) and (11.2±4.3) d, respectively( Z=6.722, P<0.05). Conclusions:The triple combination antiviral therapy of abidol, lopinavir/litonavir and rIFNα-2b shows shorter viral shedding time and shorter hospitalization time, compared with the dual combination antiviral therapy; and the earlier starting triple combination antiviral therapy will result in better antiviral efficacy.

ABSTRACT

Objective:To compare the safety and efficacy of medial-lateral pinning (MLP) and lateral pinning (LP) in pediatric supracondylar humeral fractures.Methods:According to PRISMA procedure, the randomized controlled trial (RCT) of pediatric supracondylar humeral fractures in PubMed (Medline), EMBASE, the Cochrane Library databases (Cochrane Controlled Trials Register for RCTs) and Wanfang Data from 1 January, 1990 to 1 January, 2020 were retrieved. Two researchers independently extracted the data and evaluated the quality of the original studies; the random-effects model was used for analysis.Results:A total of 4 679 original literatures were retrieved and 11 literatures were finally included, involving 920 children. Meta analysis results showed that there were no statistical differences in excellent ratio of elbow joint function (Flynn criteria), incidence of iatrogenic nerve injury and incidence of pin tract/ superficial infection between MLP group and LP group: 74.3% (255/343) vs. 72.9% (250/343), 6.1% (16/262) vs. 1.6% (4/246) and 5.3% (14/264) vs. 7.6% (20/262); RR = 0.98, 0.43 and 1.31; 95% CI 0.90 to 1.07, 0.18 to 1.03 and 0.64 to 2.67, P>0.05; the incidence of reduction loss in MLP group was significantly lower than that in LP group: 16.6% (51/307) vs. 23.9% (72/301), and there was statistical difference ( RR = 1.39, 95% CI 1.02 to 1.89, P = 0.04). Conclusions:MLP fixation and LP fixation are equally efficacious for supracondylar humeral fractures in children. MLP fixation may reduce the risk of reduction loss without increasing the risk of iatrogenic nerve injury. Manual reduction and MLP percutaneous Kirschner wire fixation for the treatment of displaced supracondylar humeral fractures in children is recommended.
