Methods A total of 23 200 subjects who underwent physical examination in 25 public hospitals in Xi'an from January 2019 to January 2023 were selected as the research objects. The basic Information of the patients was derived through the Hospital Information System (HIS), and all subjects underwent 13C-breath test and gastroenterological endoscope. ArcGIS 10.6 software was used to draw a statistical map of Hp infection in Xi 'an for spatial autocorrelation analysis. Hp infection in patients with different gastrointestinal tumors was analyzed. Results In this study population, there were 10 858 cases of Hp infection , with an infection rate of 46.80% ; among them , 5 491 cases were male, with an infection rate of 46.60% , and 5,367 cases were female, with an infection rate of 47.01% , and there was no significant difference in the infection rate between genders (P>0.05). The prevalence of HP infection was higher in the 30-year-old and 20-year-old groups, 55.62% and 42.71%, respectively, and the infection rate showed a first increase and then a decreasing trend with age (χ2trend = 6201.21, 6945.22 , P2=13.49, 16.16, 17.27, 24.66, P<0.05 for all). Conclusion The distribution of Hp infection in the physical examination population of Xi'an city has the characteristics of spatial aggregation and is related to gastrointestinal tumor diseases. It is suggested to carry out Hp infection education for the population in key areas to prevent the occurrence of gastrointestinal tumor diseases.
ABSTRACT
Objective To explore the therapeutic effect of "jian pi yi qi yang xue zhi tong" for treating bone metastasis of breast cancer and the clinical effect of improving pain symptoms. Methods A total of 80 patients with bone metastases from breast cancer were admitted. They were randomly divided into an observation group and a control group according to the random-number-table method. The control group was treated with zoledronic acid, whereas the observation group was treated with jian pi yi qi yang xue zhi tong prescriptions based on the control group. We compared the differences in the effects of different treatment plans on patients' pain symptoms, physical condition, and quality of life, as well as TNF-α, IL-6, and CRP levels. Results No significant difference was found in pain scores, physical condition scores, sleep quality scores, and quality of life scores, as well as CRP, IL-6, and TNF-α levels between the two groups of patients before treatment (all P > 0.05). At one, two, and four months after treatment, the pain scores of both groups of patients decreased, with the observation group having lower scores than the control group (P < 0.05). The total pain-relief rate of the observation group was higher than that of the control group (P < 0.05). After treatment, the sleep quality scores and the levels of CRP, IL-6, and TNF-α decreased, with the observation group having lower values than the control group (P < 0.05). The physical condition scores and the quality of life scores of both groups improved, with the observation group having higher values than the control group (P < 0.05). Conclusion In patients with bone metastases from breast cancer, oral treatment with jian pi yi qi yang xue zhi tong prescription has a significant effect. It substantially improves the pain symptoms, enhances the quality of sleep and life of patients, and reduces the levels of CRP, IL-6, and TNF-α.
ABSTRACT
Objective To observe the effect of catgut implantation at acupoint(CIAA)on the learning and memory function,hippocampal microangiogenesis,and the mRNA and protein expression of angiopoietin-1(Ang-1)/vascular endothelialgrowth factor(VEGF)and its receptor TEK tyrosine kinase(TIE2)/VEGF receptor 2(VEGFR2)in rats with vascular dementia(VD).To explore the mechanism of catgut implantation at acupoint in preventing and treating VD.Methods Using a random number table,VD rats were divided into a model group,a nimodipine group,and an catgut implantation at acupoint group,and a sham operation group was set up,with 10 rats in each group.On the 7th day after surgery,the treatment groups were given catgut implantation at acupoint and nimodipine gastric lavage for 21 days.After treatment,Morris water maze behavioral test was performed.HE staining was used to observe hippocampal CA1 tissue.CD34 immunohistochemical staining was used to detect hippocampal microvascular density(MVD).Real-time PCR and Western blotting were used to detect the mRNA and protein expression of Ang-1/VEGF and its receptor TIE2/VEGFR2 in the hippocampus.Results Compared with the model group,the average escape latency of the other groups was significantly shortened,and the target quadrant residence time was significantly prolonged(P<0.01,P<0.05).Compared with the model group,the number of nucleolus and well-formed pyramidal cells in hippocampal CA1 area of the catgut implantation at acupoint group and the nimodipine group increased in varying degrees,and they were arranged more closely,with only a few cells scattered and swollen.In the sham surgery group,a few CD34 positive cells were scattered.The treatment groups had more closely distributed CD34 positive cells with significant staining compared to the model group.The MVD of the model group was significantly higher than that of the sham surgery group(P<0.01).Both nimodipine group and catgut implantation at acupoint group had higher MVD than the model group(P<0.05,P<0.01).Compared with the sham surgery group,the mRNA and protein expression of Ang-1/VEGF and its receptor TIE2/VEGFR2 in the model group increased significantly(P<0.01,P<0.05).Compared with the model group,both nimodipine group and catgut implantation at acupoint group had higher mRNA and protein expression of Ang-1/VEGF and its receptor TIE2/VEGFR2(P<0.01,P<0.05).Conclusion Catgut implantation at acupoint can improve the learning and memory abilities in VD rats,promote hippocampal microvascular angiogenesis,which may be related to the up-regulation of Ang-1/VEGF and its receptor TIE2/VEGFR2 mRNA and protein expression.
ABSTRACT
Objective To study the applicability and optimization of computer simulation methods during the allocation of health care providers for medical evacuation on board medical trains.Methods Using Anylogic as a simulation modeling tool,the process of mass evacuation of the injured by means of medical trains was simulated.The simulated process of rescue involved the generation,categorization,treatment and surgery of the injured individuals.The allocation of health care resources was assessed based on the different rates at which the injured arrived.Results In the carriage for mild to moderate patients,24 doctors and 36 nurses could meet the need of treatment.In the carriage for critically ill ones,4 doctors and 6 nurses could meet the need when the rate at which the injured arrived was 100-200 people/an hour.When the injured arrived at the rate of 300-476 people/an hour,4 doctors and 8 nurses were needed.Conclusion Computer simulation can be feasibly used to study the allocation of human resources for health care,which can facilitate decision-making about mass evacuation of injured personnel by means of medical trains.
ABSTRACT
Objective:To analyze the predictive value of six hormonal changes in pregnant women with scarred uterus for the occurrence of oligohydramnios in their second pregnancy.Methods:A retrospective study was conducted to select the clinical data of 54 pregnant women with hypohydramnios in scarred uterus who were admitted to the First People’s Hospital of Suzhou from May. 2021 to Mar. 2023. They were included in the oligohydramnios group, and another 54 patients with normal amniotic fluid in scar uterus re-pregnancy during the same period were selected and included in the normal amniotic fluid group. Both groups of postpartum women underwent six hormone tests, including follicle stimulating hormone (FSH), luteinizing hormone (LH), estradiol (E 2), progesterone (P), testosterone (T), and prolactin (PRL). Two sets of baseline data were collected and binary logistic analysis was used to investigate the relationship between six hormones and oligohydramnios in women with scarred uterus during re-pregnancy. Receiver operating characteristic curve (ROC) was adopted to evaluate the six hormonal factors in predicting oligohydramnios in pregnant women with scar uterus during re pregnancy. The restricted cubic spline method combining spline function and logistic regression were used to analyze the dose-response relationship between six hormones and oligohydramnios in scar pregnant women during re-pregnancy. Results:The proportion of multiple pregnant women in the oligoamnios group [20.37% (11/54) ] was higher than that in the normal amniotic fluid group [5.56% (3/54) ] ( P < 0.05). The levels of FSH, E 2, P and PRL in oligohydramnios group were lower than those in normal amniotic fluid group [ (8.11±1.83) IU/L, (125.61±61.43) p /L, (16.33±3.15) mmol /L, (315.15±87.63) mIU/L],[ (9.87±2.05) IU/L, (148.52±50.57) pg/L, (20.14±4.07) mmol/L, (366.18±99.36) mIU/L] ( P<0.05) ; The levels of LH and T in oligohydramnios group [ (18.65±7.16) IU/L, (1.75±0.19) mmol/L] were compared with those in normal amniotic fluid group [ (20.67±8.53) IU/L, (1.73±0.11) mmol/L] and there was no significant difference between the two groups ( P<0.05). The results of binary logistic regression analysis showed that multiple pregnancy ( OR=11.507, 95% CI: 2.174-60.902, P=0.004) was a risk factor for recurrent oligohydramnios in women with scarred uterus. The high expression of FSH ( OR=0. 620, 95% CI: 0.224-0.845, P=0.001), E 2 ( OR=0.988, 95% CI: 0.978-0.998, P=0.021), and P ( OR=0.750, 95% CI: 0.645-0.873, P<0.001) was a protective factor for oligohydramnios in pregnant women with scar uterus during re-pregnancy. The ROC curve was plotted, and the results showed that AUC of FSH, P, and combined detection for predicting oligohydramnios in pregnant women with scarred uterus during re-pregnancy were 0.754, 0.768, and 0.870, respectively. The correlation between serum levels of FSH, E 2, and P and the occurrence of oligohydramnios in pregnant women with scarred uterus during re-pregnancy showed a linear dose-response relationship ( P<0.05). The levels of serum FSH, E 2, and P were negatively correlated with the occurrence of oligohydramnios in pregnant women with scar uterus. Especially when FSH<9.255 IU/L, E 2<158.465 pg/L, P<19.000 mmol/L, the occurrence of oligohydramnios in pregnant women with scar uterus increased with the decrease of FSH, E 2, and P levels. Conclusion:The six hormonal changes in pregnant women with scar uterus are closely related to the occurrence of oligohydramnios during re-pregnancy, and can effectively predict the risk of oligohydramnios during re-pregnancy.
ABSTRACT
Objective:To investigate the diagnostic value and imaging characteristics of MRI combined with 18F-fluorodeoxyglucose (FDG) positron-emission tomography (PET)/CT in focal cortical dysplasia (FCD) complicated with refractory epilepsy. Methods:A retrospective analysis was performed on 42 patients with FCD complicated with refractory epilepsy who were admitted to the Affiliated Hospital of Jining Medical University from January 2017 to December 2022. All patients underwent preoperative MRI and 18F-FDG PET/CT, and PET/MRI fusion was performed on the images. Chi-square test and Kappa consistency test were used to compare the localization diagnostic efficacy of PET/CT, MRI and PET/MRI fusion for epileptic foci. The patients were categorized based on gender, lesion location, pathological type, seizure type, and efficacy. Independent sample t-test and analysis of variance were used to compare maximum standardized uptake (SUVmax) values and asymmetry index (AI) of the patients between different groups. Results:Among the 42 patients, the positive rates of MRI, PET/CT, PET/MRI fusion examinations were 85.7%(36/42), 95.2%(40/42), 100.0%(42/42), the lateral localization rates were 71.4%(30/42), 92.9%(39/42), 95.2%(40/42), and the localization rates were 57.1%(24/42), 81.0%(34/42), 88.1%(37/42), respectively. There were significant differences in the lateral localization rates and localization rates of epileptogenic foci between MRI and PET/CT (χ 2=6.574, P=0.010; χ 2=5.570, P=0.018). There were significant differences in the positive rates of lesions, the lateral localization rates and the localization rates of epileptogenic foci between MRI and PET/MRI fusion (χ 2=6.385, P=0.012; χ 2=8.571, P=0.003; χ 2=10.118, P=0.001). There were no significant differences in the positive rates of lesions between MRI and PET/CT, and in the positive rates of lesions, the lateral localization rates and localization rates of epileptogenic foci between PET/CT and PET/MRI fusion (χ 2=2.184, P=0.139; χ 2=2.024, P=0.155; χ 2=0.210, P=0.647; χ 2=0.819, P=0.365). The Kappa consistency test of PET/CT and PET/MRI fusion imaging was performed for the location of epileptogenic foci, and the Kappa=0.721 was obtained, indicating that they were consistent in the location of epileptogenic foci. The SUVmax values of patients with temporal lobe epilepsy were lower, and the AI values were higher than that of patients with extra temporal lobe epilepsy (7.4±1.3 vs 9.6±1.6, 15.5±2.6 vs 12.9±2.4; t=5.154, 6.083; P=0.001, 0.001). The SUVmax values of patients with good efficacy (according to the Engel efficacy grading system, grades Ⅰ-Ⅱ indicating good efficacy) were higher, and the AI values were lower than that of patients with poor efficacy (according to the Engel efficacy grading system, grades Ⅲ-Ⅳ indicating poor efficacy; 9.5±1.9 vs 7.9±2.1, 13.5±3.3 vs 14.8±3.0; t=2.789, 3.722; P=0.042, 0.029). There were no significant differences in SUVmax and AI values among different genders, pathological types and seizure types (all P>0.05). Conclusions:The imaging characteristics of patients with different types of FCD complicated with refractory epilepsy are different. PET/MRI fusion is better than MRI in the diagnosis of FCD complicated with refractory epilepsy, and is consistent with PET/CT in the location of epileptogenic foci.

ABSTRACT
OBJECTIVE@#To determine the role of Tripterygium wilfordii multiglycoside (TGW) in the treatment of psoriatic dermatitis from a cellular immunological perspective.@*METHODS@#Mouse models of psoriatic dermatitis were established by imiquimod (IMQ). Twelve male BALB/c mice were assigned to IMQ or IMQ+TGW groups according to a random number table. Histopathological changes in vivo were assessed by hematoxylin and eosin staining. Ratios of immune cells and cytokines in mice, as well as PAM212 cell proliferation in vitro were assessed by flow cytometry. Pro-inflammatory cytokine expression was determined using reverse transcription quantitative polymerase chain reaction.@*RESULTS@#TGW significantly ameliorated the severity of IMQ-induced psoriasis-like mouse skin lesions and restrained the activation of CD45+ cells, neutrophils and T lymphocytes (all P<0.01). Moreover, TGW significantly attenuated keratinocytes (KCs) proliferation and downregulated the mRNA levels of inflammatory cytokines including interleukin (IL)-17A, IL-23, tumor necrosis factor α, and chemokine (C-X-C motif) ligand 1 (P<0.01 or P<0.05). Furthermore, it reduced the number of γ δ T17 cells in skin lesion of mice and draining lymph nodes (P<0.01).@*CONCLUSIONS@#TGW improved psoriasis-like inflammation by inhibiting KCs proliferation, as well as the associated immune cells and cytokine expression. It inhibited IL-17 secretion from γ δ T cells, which improved the immune-inflammatory microenvironment of psoriasis.

Objective To understand the respiratory protection competency of staff in hospitals.Methods Staff from six hospitals of different levels and characteristics in Beijing were selected,including doctors,nurses,medical technicians,and servicers,to conduct knowledge assessment on respiratory protection competency.According to exposure risks of respiratory infectious diseases,based on actual cases and daily work scenarios,content of respira-tory protection competency assessment was designed from three aspects:identification of respiratory infectious di-seases,transmission routes and corresponding protection requirements,as well as correct selection and use of masks.The assessment included 6,6,and 8 knowledge points respectively,with 20 knowledge points in total,all of which were choice questions.For multiple-choice questions,full marks,partial marks,and no mark were given respective-ly if all options were correct,partial options were correct and without incorrect options,and partial options were correct but with incorrect options.Difficulty and discrimination analyses on question of each knowledge point was conducted based on classical test theory.Results The respiratory protection competency knowledge assessment for 326 staff members at different risk levels in 6 hospitals showed that concerning the 20 knowledge points,more than 60%participants got full marks for 6 points,while the proportion of full marks for other questions was relatively low.Less than 10%participants got full marks for the following 5 knowledge points:types of airborne diseases,types of droplet-borne diseases,conventional measures for the prevention and control of healthcare-associated infec-tion with respiratory infectious diseases,indications for wearing respirators,and indications for wearing medical protective masks.Among the 20 knowledge questions,5,1,and 14 questions were relatively easy,medium,and difficult,respectively;6,1,4,and 9 questions were with discrimination levels of ≥0.4,0.30-0.39,0.20-0.29,and ≤0.19,respectively.Conclusion There is still much room for hospital staff to improve their respiratory protection competency,especially in the recognition of diseases with different transmission routes and the indications for wearing different types of masks.
ABSTRACT
Objective Starting from the actual numbers of health personnel of tertiary public hospitals of Traditional Chinese Medicine(TCM),to quantitatively analyze the influencing factors on the allocation of human resources and obtain a prediction model.Methods The balanced panel data from 517 Tertiary Public TCM Hospitals in the period of 2011-2020 were collected,and the two-way fixed effects model was used to empirically analyze the impact of scale,demand and other factors on the actual number of health personnel in these hospitals.Result The number of beds is a key factor affecting the human resource allocation of Public TCM Hospitals,and various factors such as de-mand,policy,price,efficiency,and administrative management also have significant impacts on the allocation.The demand for outpatient services,government financial support,and efficiency of resource utilization are all promoting factors,while the increase in human resource prices,income generation efficiency,and administrative manage-ment levels have negative effects.A prediction model is proposed.Conclusion The planning principle of matching bed numbers with human resources allocation is in line with the actual environment.When predicting the total personnel allocation or authorized strength,various factors should also be fully considered,which can provide reference for the formulation of human resource policies in Public TCM Hospitals.

ABSTRACT
Crossmodal transfer is the ability to apply the knowledge acquired in one sensory modality to another. Researches on crossmodal transfer investigate how the brain represents information from different sensory modalities, and provide new insights to improve cognitive processing efficiency and reduce repeated learning. To clarify the characteristics and mechanism of crossmodal transfer, this article first introduced the crossmodal transfer effect in different field of research, such as object recognition, category learning, and time perception. After that, the theoretical researches on the representation type of crossmodal transfer were reviewed, mainly including multisensory theory and multisensory mental imagery theory as well as the supportive and opposite findings. The research progresses on the neural mechanism of crossmodal transfer using ERP and fMRI techniques were introduced, mainly including metamodal theory, and multisensory reverse hierarchy theory as well as the supportive and opposite findings. The objective and subjective factors which influenced crossmodal transfer effect were sorted out, in which we suggested that the modality dominance phenomenon supports the metamodal theory, while other factors such as sensory experience, age, setting of learning tasks and stimulus features support theories such as the multisensory hypothesis. Finally, we described the potential applications of the current research findings on crossmodal transfer and pointed out future research questions in this field.
ABSTRACT
BACKGROUND@#Tri-ponderal mass index (TMI) has been reported to be a more accurate estimate of body fat than body mass index (BMI). This study aims to compare the effectiveness of TMI and BMI in identifying hypertension, dyslipidemia, impaired fasting glucose (IFG), abdominal obesity, and clustered cardio-metabolic risk factors (CMRFs) in 3- to 17-year-old children.@*METHODS@#A total of 1587 children aged 3 to 17 years were included. Logistic regression was used to evaluate correlations between BMI and TMI. Area under the curves (AUCs) were used to compare discriminative capability among indicators. BMI was converted to BMI- z scores, and accuracy was compared by false-positive rate, false-negative rate, and total misclassification rate.@*RESULTS@#Among children aged 3 to 17 years, the mean TMI was 13.57 ± 2.50 kg/m 3 for boys and 13.3 ± 2.33 kg/m 3 for girls. Odds ratios (ORs) of TMI for hypertension, dyslipidemia, abdominal obesity, and clustered CMRFs ranged from 1.13 to 3.15, higher than BMI, whose ORs ranged from 1.08 to 2.98. AUCs showed similar ability of TMI (AUC: 0.83) and BMI (AUC: 0.85) in identifying clustered CMRFs. For abdominal obesity and hypertension, the AUC of TMI was 0.92 and 0.64, respectively, which was significantly better than that of BMI, 0.85 and 0.61. AUCs of TMI for dyslipidemia and IFG were 0.58 and 0.49. When 85th and 95th of TMI were set as thresholds, total misclassification rates of TMI for clustered CMRFs ranged from 6.5% to 16.4%, which was not significantly different from that of BMI- z scores standardized according to World Health Organization criteria.@*CONCLUSIONS@#TMI was found to have equal or even better effectiveness in comparison with BMI in identifying hypertension, abdominal obesity, and clustered CMRFs TMI was more stable than BMI in 3- to 17-year-old children, while it failed to identify dyslipidemia and IFG. It is worth considering the use of TMI for screening CMRFs in children and adolescents.

Lung cancer is one of the common malignant tumors in the world, and its incidence and mortality is increasing year by year. Interactions between tumor cells and immune cells in the tumor microenvironment(TME) affect tumor proliferation, infiltration, and metastasis. Tumor-associated macrophages(TAMs) are prominent components of TME, and they have dual regulation effects on malignant progression of lung cancer. The number, activity, and function of M2 macrophages are related to the poor prognosis of lung cancer, and M2 macrophages participate in tumor angiogenesis and immune escape. It has been proved that traditional Chinese medicines(TCMs) and their active ingredients can enhance the antitumor effects, reduce the toxicity of chemotherapy and radiotherapy, and prolong the survival rates of patients with cancer. This paper summarized the role of TAMs in the lung cancer initiation and progression, explored the molecular mechanism of TCM in regulating the recruitment, polarization phenotype, activity, and expression of related factors and proteins of TAMs, and discussed related signal pathways in the prevention and treatment of lung cancer based on the TCM theory of "reinforcing healthy qi and eliminating pathogen". This paper is expected to provide new ideas for the immunotherapy of targeted TAMs.

Objective: To examine the clinical effect of auxiliary liver transplantation with ultra-small volume graft in the treatment of portal hypertension. Methods: Twelve cases of portal hypertension treated by auxiliary liver transplantation with small volume graft at Liver Transplantation Center,Beijing Friendship Hospital, Capital Medical University between December 2014 and March 2022 were studied retrospectively. There were 8 males and 4 females,aged 14 to 66 years. Model for end-stage liver disease scores were 1 to 15 points and Child scores were 6 to 11 points. The grafts was derived from living donors in 9 cases,from split cadaveric donors in 2 cases,from whole cadaveric liver of child in 1 case. The graft recipient body weight ratios of 3 cadaveric donor livers were 0.79% to 0.90%, and of 9 living donor livers were 0.31% to 0.55%.In these cases, ultra-small volume grafts were implanted. The survivals of patient and graft, complications, portal vein blood flow of residual liver and graft, abdominal drainage and biochemical indexes of liver function were observed. Results: All the grafts and patients survived. Complications included outflow tract torsion in 2 cases, acute rejection in 1 case, bile leakage in 1 case, and thyroid cancer at the later stage of follow-up in 1 case, all of which were cured. The torsion of outflow tract was attributed to the change of anastomotic angle after the growth of donor liver. After the improvement of anastomotic method, the complication did not recur in the later stage. There was no complication of portal hypertension. The measurement of ultrasonic portal vein blood flow velocity showed that the blood flow of residual liver decreased significantly in the early stage after operation, and maintained a very low blood flow velocity or occlusion in the long term after operation, and the blood flow of transplanted liver was stable. Conclusions: Auxiliary liver transplantation can implant ultra-small donor liver through compensation of residual liver. This method may promote the development of living donor left lobe donation and split liver transplantation. However, the auxiliary liver transplantation is complex, and it is difficult to control the complications. Therefore, this method is currently limited to centers that are skilled in living related liver transplantation and that have complete ability to monitor and deal with complications.

Objective: To explore the characteristics, patterns of multimorbidity and the impact on quality of life and the prognosis of middle-aged and elderly patients with chronic obstructive pulmonary disease (COPD). Methods: This is a cross-sectional study. From January 2012 to December 2021, 939 middle-aged and elderly COPD patients hospitalized in Beijing Hospital were selected by the convenient sampling method. The basic data of patients and the date of 16 common chronic diseases were collected. Patterns of multimorbidity were depicted by cluster analysis. Generalized linear regression model and logistic regression were used to evaluate the multimorbidity patterns and their prognosis. Results: At least one multimorbidity existed among 93.40% of COPD patients, and the median number of multimorbidity was 3. The top five multimorbidity among the patients were hypertension (57.93%, 544/939), coronary heart disease (33.76%,317/939), heart failure (31.95%,300/939), hyperlipidemia (31.63%,297/939) and arrhythmia (27.37%,257/939). Four multimorbidity patterns were identified, cardiometabolic and metabolic multimorbidity, kidney disease multimorbidity, respiratory-digestive-tumor multimorbidity and other multimorbidity. Cardiometabolic and metabolic multimorbidity was most common (590/939, 62.83%). Compared with non-cardiometabolic and metabolic multimorbidity, the incharge ADL score of patients with this multimorbidity decreased by 7 points (95%CI:-11.22- -3.34), Correspondingly, patients with kidney disease multimorbidity decreased by 14 points (95%CI:-24.12- -3.30) on the incharge score. The presence or absence of kidney disease multimorbidity had the greatest impact on discharge score, which was reduced by 12 points in comparison with patients without this multimorbidity (95%CI:-22.43- -2.40). ICU admission is mostly affected by the presence of cardiometabolic and metabolic multimorbidity (OR=2.44, 95%CI: 1.51-3.92) and kidney disease multimorbidity (OR=2.58, 95%CI: 1.01-6.60). The risk of death is the highest for cardiometabolic and metabolic multimorbidity (OR=2.24, 95%CI: 1.19-4.21). Conclusion: Multimorbidity is common in COPD patients. The most common pattern is cardiometabolic and metabolic multimorbidity. Cardiometabolic and metabolic multimorbidity and kidney disease multimorbidity significantly affect the quality of life and often associate with a poor prognosis.

Methods From January to April 2021, the convenience sampling method was used to collect data based on the online platform and the Department of Pediatrics and Adolescent Gynecology of the Children's Hospital of Zhejiang University School of Medicine. The data were analyzed by descriptive analysis, Chi-square test, and logistic regression. Results A total of 864 questionnaires were collected, and 846 valid questionnaires were obtained after screening, with an effective rate of 97.9%. 13.57% of mothers and 3.09% of girls were vaccinated, and the vaccine awareness rate was 68.43%. 87.22% of parents were willing to bring their children for vaccination. Risk perception (OR=4.79, 95% CI: 2.22-10.35), willingness to vaccinate themselves (OR =29.01, 95% CI: 12.62-66.69), awareness of sex education (OR =3.73, 95% CI: 1.08-12.83) and whether the vaccines were free (P<0.001) were related to whether parents were willing to vaccinate their children. Conclusion Parents of children aged 9-14 have high awareness of HPV and HPV vaccine and are willing to vaccinate their children with HPV vaccine , but the vaccination rate in children is low. Disease perception, willingness to vaccinate, awareness of sex education, and whether vaccines are free are all the factors influencing parents' willingness to vaccinate children.
ABSTRACT
Objective:To investigate the effects of Qingfei Shenshi Decoction on the expressions of matrix metalloproteinase-2 (MMP-2) and MMP-9 and tissue inhibitor of metalloproteinase timps-1 (TIMP-1) in lung tissue of asthma mice.Methods:Totally 50 male BALB/C mice were divided into 5 groups: normal group, model group, dexamethasone group, Qingfei Shenshi Decoction low- and high-dosage groups (10 mice /group) according to random number table method. Asthma model mice were prepared by ovalbumin (OVA) challenge method. After successful modeling, the dexamethasone group was given dexamethasone for gavage at the rate of 1.56 mg/kg, while Qingfei Shenshi Decoction groups were given high and low doses of Qingfei Shenshi Decoction for gavage at the rate of 14.235 g/kg and 28.470 g/kg, respectively. Normal group and model group were given 0.9% sodium chloride solution by gavage. At the end of gavage administration for 4 weeks, the airway reactivity (Penh value) in each group was detected; HE staining was used to observe the pathological changes of lung tissue; the contents of interleukin-6 (IL-6), interleukin-1β (IL-1β) and tumor necrosis factor -α (TNF-α) in alveolar lavage fluid were determined by enzyme Linked immunosorbent assay (ELISA); the expressions of MMP-2, MMP-9 and TIMP-1 in lung tissue were detected by Western-blot.Results:Compared with model group, the damage of airway wall and alveolar wall of lung tissue in Qingfei Shenshi Decoction groups was significantly reduced. Compared with model group, the Penh value, IL-6, IL-1β and TNF-α levels in Qingfei Shenshi Decoction low- and high-dosage groups decreased ( P<0.05), and the expressions of MMP-9, MMP-2 and TIMP-1 in lung tissue decreased ( P<0.05), with a certain dose dependence. Conclusion:Qingfei Shenshi Decoction can effectively alleviate airway inflammation, reduce airway hyperresponsiveness, improve lung function and inhibit airway remodeling in asthmatic mice. Its mechanism may be related to down-regulating the expressions of MMP-2, MMP-9 and TIMP-1.
ABSTRACT
Objective:To explore the application and effect of scenario simulation teaching in ST-segment elevation myocardial infarction (STEMI) course for emergency training of "5+3" professional master.Methods:A randomized controlled trial was conducted among 48 "5+3" professional masters who would rotate in the emergency department, to compare the test results of the total and three scenes between scenario simulation teaching group ( n=24) and traditional teaching group ( n=24). The STEMI teaching was carried out through simulating the emergency room, standardized patients and first-aid simulators in the simulation teaching group, and the traditional teaching group was taught by conventional classroom teaching. After the class, "Theoretical Examination" and "Questionnaire Survey" were used to evaluate the teaching effect. The former was further divided into "first diagnosis and differential diagnosis of chest pain", "fast identification and processing of STEMI" and "rescue of cardiac arrest" for inter-group and intra-group evaluation. SPSS 20.0 was used to conduct t-test. Results:In the theoretical examination, the scenario simulation teaching group was superior to the traditional teaching group in the test of emergency processing for STEMI course [(82.38±2.41) vs . (68.00±1.95), t=4.64, P<0.001]. In the sub-analysis of scenario simulation teaching group, students in the role-play group had significantly higher scores than others in the non-role-play group [(90.50±3.04) vs . (79.67±2.79), t=2.09, P=0.049]. Scenario simulation teaching group was also superior to traditional teaching group in the "Questionnaire Survey". Conclusion:In the training and teaching of STEMI emergency processing, scenario simulation teaching group proves to be superior to traditional teaching, which deserves further promotion.
ABSTRACT
Objective:To explore the influencing factors of tuberculosis related health behaviors among college freshmen with health belief model, so as to provide a scientific basis for the intervention of health behaviors among students.Methods:From January to February 2021, the questionnaire survey was conducted among 5 254 college freshmen from 11 universities.The survey included general demographic data, tuberculosis related health behaviors, and tuberculosis related knowledge, disease threat perception and disease policy cognition.The SPSS 23.0 software was used for data analysis, independent sample t-test and one-way ANOVA were used for inter group comparison, and Logistic regression analysis was used to explore the influencing factors of health behavior holding. Results:The total score of tuberculosis related health behaviors among freshmen was 3~12 (11.01±1.10), and the overall holding rate of tuberculosis related health behaviors was higher.Male( B=-0.753, OR(95% CI)=0.471(0.417-0.531)), and tuberculosis history ( B=-1.088, OR(95% CI)=0.337(0.157-0.722)) were risk factors for tuberculosis related health behaviors among freshmen.Birth in city( B=0.117, OR(95% CI)=1.124(0.944-1.338)), father's education level college /undergraduate and above ( B=0.177, OR(95% CI)=1.194(1.024-1.392)), mother's education level high school/secondary school( B=0.356, OR(95% CI)=1.428(1.126-1.810)), college/undergraduate and above( B=0.194, OR(95% CI)=1.214(1.029-1.433)), take the initiative to understand tuberculosis knowledge ( B=0.208, OR(95% CI)=1.231(1.095-1.385)), higher tuberculosis knowledge score ( B=0.088, OR(95% CI)=1.092(1.041-1.145)), higher disease threat perception score ( B=0.082, OR(95% CI)=1.086(1.031-1.144)) and higher disease policy cognition score( B=0.320, OR(95% CI)=1.378(1.265-1.500)) were protective factors for tuberculosis related health behaviors among first-year undergraduates(all P<0.05). Conclusion:The application of health belief model can analyze and explain the influencing factors of tuberculosis-related health behaviors of freshmen, which is helpful to strengthen health education and advocate tuberculosis-related health behaviors.
