ObjectiveTo explore the central neuroregulation mechanism of heat-sensitive moxibustion for knee osteoarthritis on pain relief. MethodsThirty patients who did not have experience of Deqi （得气） during heat-sensitive moxibustion treatment were assigned to the "non-Deqi group"， while another 30 patients who had experience of Deqi were assigned to the "Deqi group". Both groups received moxibustion at the left Heding （EX-LE2） acupoint. In the Deqi group， after the patients experienced sensation of Deqi at the acupoint， moxibustion was applied at approximately 3 cm from the skin for 10 minutes； in the non-Deqi group， moxibustion was also applied at approximately 3 cm from the skin for 10 minutes. Both groups received treatment once daily for 10 consecutive days. Knee joint pain was assessed before and after treatment using the visual analog scale （VAS）. Resting-state functional magnetic resonance imaging （rs-fMRI） scans were performed on all participants before the first treatment session and after the final session on the 10th day. The fractional amplitude of low-frequency fluctuations （fALFF） maps before and after treatment were processed using the SPM12 module by MATLAB. ResultsAfter treatment， VAS scores in both groups were significantly lower than before treatment （P＜0.05 or P＜0.01）， with the Deqi group showing significantly lower VAS scores than the non-Deqi group （P＜0.01）. Compared to before treatment， the Deqi group exhibited significant activation in the prefrontal cortex （t = 6.28）， white matter （t = 6.36）， and left temporal lobe （t = 9.33）， while significant inhibition was observed in the occipital lobe （t = -9.86） and right cerebrum （t = -4.54， P＜0.01）； in the non-Deqi group， significant changes after treatment were observed in the left occipital lobe （t = -6.42）， left medial frontal gyrus （t = -4.35）， left middle frontal gyrus （t = -4.74）， right superior frontal gyrus （t = -4.82）， right superior temporal gyrus （t = -6.61）， and right cerebellar posterior lobe （t = -8.64）， all of which were in inhibited states （P＜0.01）. Compared to the non-Deqi group， the Deqi group exhibited significant activation after treatment in the external nucleus （t = 5.77）， white matter （t = 3.58）， right cerebrum （t = 5.84）， left cerebellum （t = 5.35）， and left cerebrum （t = 4.32）， while significant inhibition was observed in the prefrontal cortex （t = -4.16）， occipital lobe （t = -4.87）， and precentral gyrus （t = -4.46， P＜0.01）. ConclusionsHeat-sensitive moxibustion provides better analgesic effects for knee osteoarthritis under state of Deqi. Its central neuroregulation mechanism may be related to the involvement of the frontal lobe， temporal lobe， occipital lobe， external nucleus， white matter， right cerebrum， left cerebellum， left cerebrum， and precentral gyrus in modulating pain signals.

OBJECTIVE To investigate the effect of eukaryotic translation elongation factor 1A1(eEF1A1)on the replication of vesicular stomatitis virus(VSV)and Herpes simplex virus 1(HSV-1)to identify a potential target for broad-spectrum regulation of viruses.METHODS Small interfering RNA(si-eEF1A)was transfected into human skin fibroblasts(BJ-5ta)to inhibit the expression of eEF1A1,and the negative control group was set up.The transfection efficiency was detected by real-time fluo-rescence quantitative PCR(RT-qPCR)and Western blotting,the cell model of eEF1A1 gene silencing was constructed.The cell model was infected with VSV,the gene copy number and protein expression of VSV in the cells were detected.The cell model was infected with HSV-1,the mRNA and protein expres-sion of HSV-1 in the cells were detected.The cell models were transfected with polyinosinic acid[Poly(I:C)]or sodium deoxyribonucleic acid(HT-DNA),respectively.The mRNA expression of interferon-β(IFN-β),C-X-C Motif Chemokine 10(CXCL10)and interferon-stimulated gene 56(ISG56)were detected by RT-qPCR.The phosphorylation expression of interferon regulatory factor 3(IRF3)and TANK binding kinase 1(TBK1)were detected by Western blotting.RESULT Compared with the negative control group,the mRNA and protein expression of eEF1A1 in the eEF1A1 gene silencing group were signifi-cantly decreased(P<0.01),the cell model of eEF1A1 gene silencing was successfully constructed.Compared with the negative control group,the VSV gene copy number of the eEF1A1 gene silencing group decreased by 70%-80%.The VSV protein expression decreased significantly(P<0.01).The mRNA expression of HSV-1 was decreased by 50%-60%,and the protein expression of HSV-1 was significantly decreased(P<0.01).After stimulation with Poly(I:C)or HT-DNA,compared with the negative control group.there was no significant difference in the mRNA expressions of IFN-β,ISG56 and CXCL10 and the protein phosphorylation expression of IRF3 and TBK1 in the eEF1A1 gene silencing group.CONCLUSION eEF1A1 silencing can inhibit VSV and HSV-1 virus replication,suggesting that eEF1A1 has a potential broad-spectrum regulatory effect on RNA viruses and DNA viruses,and may not recog-nize activated immune pathways through intracellular nucleic acid recognition.

OBJECTIVE To evaluate the consistency between the quetiapine LC-MS/MS kit and the laboratory-built method(reference method) in the detection results of quetiapine therapeutic drug monitoring. METHODS A total of 120 remaining plasma samples were collected from patients receiving quetiapine therapeutic drug monitoring from March to October in 2021. The plasma concentration of quetiapine was detected by kit and reference method respectively.

Objective:To explore the application effect of standardized patient combined with situational simulation teaching in the course of Intensive and Critical Diseases Care among higher vocational college students.Methods:A total of 66 nursing students in direction of intensive care from Batch 2015 and 60 ones from Batch 2016 were selected as the control group and the experiment group respectively. The control group adopted traditional teaching method, while the experiment group adopted the model of standardized patient combined with situational simulation teaching on the basis of traditional teaching methods. Before teaching, we designed the standard cases of the course, set up and trained the standardized patient team members. Then the standardized patient combined with situational simulation teaching was applied to the experimental teaching of the course. At the end of the course, the comparison of the theoretical examination score and the operational examination score of the two groups of students was made, and the self-designed questionnaire survey for the experimental group was used to evaluate the teaching effect.Results:The theoretical examination score [(82.80±4.17) points] and the operational examination score [(85.90±1.85) points] of students in the experiment group were higher than those of students in the control group [(80.74±3.15) points vs. (83.82±1.91) points], with significant differences ( P<0.01). The results of self-designed questionnaire survey showed that more than 90.0% of the students from the experiment group thought that this teaching mode could improve their interest in learning and subjective initiative; more than 76.7% thought that this teaching mode could improve their own abilities such as observation of disease changes, communication, teamwork and clinical thinking; more than 93.3% recognized the application of this teaching mode. Conclusion:The application of standardized patient combined with situational simulation teaching could improve the theoretical knowledge and operational skills of the students, and could also train the students' comprehensive quality such as clinical thinking, emergency handling ability, communication ability and so on, so as to improve the teaching effect.

Objective:To understand the employment psychology of college students in traditional Chinese medicine universities through analyzing relevant influencing factors, and to provide solutions to improve employment quality of the medical students.Methods:An online questionnaire survey on employment psychology and employment situation was conducted from August to September in 2017 among 384 students who had graduated from Longhua Hospital of Shanghai University of Traditional Chinese Medicine from 2013 to 2017. SPSS 19.0 was used for chi-square test and linear trend test on the survey results.Results:A total of 374 valid questionnaires were recovered, with the effective recovery rate of 97.4%. The results showed that the most important factors to be considered were professional counterparts (77.01%, 288 students), salary (75.67%, 283 students) and development prospect (69.52%, 260 students) and the most important psychological characteristics were hesitation and contradiction (50.8%, 190 students) and anxiety (25.13%, 94 students). The study found that employment psychology was related to students' family situation, category, temperament and performance during their education period.Conclusion:Students have different employment psychology, which can be improved by consummating career planning, broadening employment channels, combing employment policies, supplementing professional shortcomings, and improving comprehensive skills. Meanwhile, colleges and universities can expand their practice bases, provide employment counseling, and improve education resources, speed up the construction of the second classroom, pay attention to special groups to conduct employment guidance and improve the quality of employment.

Objective:To investigate the influencing factors of hospitalization for pregnant women with influenza A.Methods:From December 2018 to February 2019, 261 pregnant women with influenza A were admitted to Beijing Ditan Hospital, Capital Medical University. The clinical data of age, gestational period, underlying diseases, time from onset to treatment, white blood cell count and lymphocyte count of these patients were collected. Data of out-patients were compared with those of inpatients. Chi-square test and multivariate logistic regression were used to analyze the influencing factors of hospitalization in pregnant women with influenza A.Results:Among the 261 cases of pregnancy with influenza A, 36 cases (13.79%) were hospitalized, of which 10 (27.78%) were hospitalized due to severe influenza complications, the other 26 cases (72.22%) were hospitalized due to pregnancy related adverse events. The proportions of hospitalized patients with age ≥30 years old, gestational period ≥28 weeks, combined with underlying diseases and lymphocyte count <1×10 9/L were 75.00%(27/36), 83.33%(30/36), 16.67%(6/36) and 50.00%(18/36), respectively, which were significantly higher than those of out-patients (47.11%(106/225), 35.56%(80/225), 0.89%(2/225) and 13.22%(16/121), respectively; χ2=9.66, 29.05, 26.00 and 22.12, respectively, all P<0.05). The proportions of inpatients and out-patients with white blood cell count ≥4×10 9/L were 97.22%(35/36) and 97.52%(118/121), respectively, and there was no significant difference ( χ2=0.01, P=0.921). Multivariate logistic regression analysis showed that age ≥30 years (odds ratio ( OR)=5.181, 95% confidence interval ( CI) 1.628-16.489, P=0.005), gestational period ≥28 weeks ( OR=11.054, 95% CI 3.233-37.796, P<0.01), lymphocyte count <1×10 9/L ( OR=6.864, 95% CI 2.237-20.729, P=0.001), and time from onset to treatment <24 h ( OR=0.076, 95% CI 0.012-0.468, P=0.005) were the influencing factors for hospitalization of pregnant women with influenza A. Conclusion:Age ≥30 years old, gestational period ≥28 weeks, lymphocyte count <1×10 9/L and time from onset to treatment <24 h are the influencing factors for hospitalization of pregnant women with influenza A.

Objective:To explore the effects of interpregnancy interval (IPI) on pregnancy outcomes of subsequent pregnancy.Methods:A multicenter retrospective study was conducted in 21 hospitals in China. Information of age, height, pre-pregnancy weight, IPI, history of diseases, complications of pregnancy, gestational age of delivery, delivery mode, and pregnancy outcomes of the participants were collected by consulting medical records of pregnant women who had two consecutive deliveries in the same hospital during 2011 to 2018. The participants were divided into 4 groups according to IPI:<18 months, 18-23 months, 24-59 months and ≥60 months. According to the WHO′s recommendation, with the IPI of 24-59 months group as a reference, to the effects of IPI on pregnancy outcomes of subsequent pregnancy were analyzed. Stratified analysis was further carried out based on age, history of gestational diabetes mellitus (GDM), macrosomia, and premature delivery, to explore the differences in the effects of IPI on pregnancy outcomes among women with different characteristics.Results:A total of 8 026 women were included in this study. There were 423, 623, 5 512 and 1 468 participants in <18 months group, 18-23 months group, 24-59 months group and ≥60 months group, respectively. (1) The age, pre-pregnancy body mass index (BMI), history of cesarean section, GDM, gestational hypertension and cesarean section delivery rate of <18 months group, 18-23 months group, 24-59 months group and ≥60 months group were gradually increased, and the differences were statistically significant ( P<0.05). (2) After adjusting for potential confounding factors, compared with women in the IPI of 24-59 months group, the risk of premature delivery, premature rupture of membranes, and oligohydramnios were increased by 42% ( OR=1.42, 95% CI: 1.07-1.88, P=0.015), 46% ( OR=1.46, 95% CI: 1.13-1.88, P=0.004), and 64% ( OR=1.64, 95% CI: 1.13-2.38, P=0.009) respectively for women in the IPI≥60 months group. No effects of IPI on other pregnancy outcomes were found in this study ( P>0.05). (3) After stratified by age and adjusted for confounding factors, compared with women in the IPI of 24-59 months group, IPI≥60 months would significantly increase the risk of oligohydramnios for women with advanced age ( OR=2.87, 95% CI: 1.41-5.83, P=0.004); and <18 months could increase the risk of premature rupture of membranes for women under the age of 35 ( OR=1.59, 95% CI: 1.04-2.43, P=0.032). Both the risk of premature rupture of membranes ( OR=1.58, 95% CI: 1.18-2.13, P=0.002) and premature delivery ( OR=1.52, 95% CI: 1.07-2.17, P=0.020) were significantly increased in the IPI≥60 months group. After stratified by history of GDM and adjusted for confounding factors, compared with women in the IPI of 24-59 months group, IPI≥60 months would lead to an increased risk of postpartum hemorrhage for women with a history of GDM ( OR=5.34, 95% CI: 1.45-19.70, P=0.012) and an increased risk of premature rupture of membranes for women without a history of GDM ( OR=1.44, 95% CI: 1.10-1.90, P=0.009). After stratified by history of macrosomia and adjusted for confounding factors, compared with women in the IPI of 24-59 months group, IPI≥60 months could increase the proportion of cesarean section for women with a history of macrosomia ( OR=4.11, 95% CI: 1.18-14.27, P=0.026) and the risk of premature rupture of membranes for women without a history of macrosomia ( OR=1.46, 95% CI: 1.12-1.89, P=0.005). After stratified by history of premature delivery and adjusted for confounding factors, compared with women in the IPI of 24-59 months group, IPI≥60 months would significantly increase the risk of premature rupture of membranes for women without a history of premature delivery ( OR=1.47, 95% CI: 1.13-1.92, P=0.004). Conclusions:Both IPI≥60 months and <18 months would increase the risk of adverse pregnancy outcomes in the subsequent pregnancy. Healthcare education and consultation should be conducted for women of reproductive age to maintain an appropriate IPI when they plan to pregnant again, to reduce the risk of adverse pregnancy outcomes in the subsequent pregnancy.
