Nuclear emergency medical rescue is one of the important courses of military medical professional education, and improving the training level of nuclear emergency medical rescue plays a very important role in improving post competency of trainees. Based on the problem of disconnection between "teaching" and "need" in the occupational education of nuclear emergency medical rescue in the past, this study proposes the curriculum goal of "the combination of three abilities" and performs the optimization and practice of the occupational education curriculum system of nuclear emergency medical rescue from the aspects of curriculum setting, curriculum content, teaching methods, and assessment and evaluation. The results show that the new curriculum system can significantly improve the comprehensive ability of nuclear emergency medical rescue among trainees and better meet the requirements for their posts, thereby playing an important role in cultivating high-quality military medical talents in nuclear emergency medical rescue.

Objective To investigate the effect of high altitude on peak expiratory flow (PEF) in elderly patients with heart failure and respiratory tract infection and its relationship with inflammatory response. Methods A total of 380 elderly patients over 60 years old with heart failure and respiratory tract infection admitted to our hospital from January 2020 to September 2022 were selected by cluster sampling method as research objects, including 190 long-term residents in high-altitude areas and 190 long-term residents in non-high-altitude areas.Information on current diseases, peak expiratory flow (PEF) levels, and inflammatory status (serum TNF) were collected- α， CRP, PCT and IL-6 levels) and other potential influencing factors; The relevant test indexes were collected at the time of enrollment (baseline) and at the time of discharge after treatment (the shortest hospital stay of 6 days and the longest hospital stay of 21 days); To compare the effects of long-term living at high altitude on PEF level and inflammatory state. The study used spss19 0 statistical software package for analysis. Results In this study, 380 elderly patients over 60 years old with heart failure and respiratory tract infection were enrolled, including 190 long-term residents in high-altitude areas (high-altitude group) and 190 long-term residents in non-high-altitude areas (control group). The mean age of patients in the high altitude group was (66.20±6.56) years old, the proportion of male patients was 53.16%, and the proportion of patients with heart failure duration less than 5 years was 70.00%. The average age of the control group was (66.93±6.77) years old, the proportion of male patients was 53.85%, and the proportion of patients with heart failure duration less than 5 years was 71.79%. The levels of PEF, FEV1 and FVC in 2 groups were higher than the baseline level at discharge (t=2.095, 7.139, 11.047, 14.594, 14.104, 12.250, all P<0.05). And the high altitude group was significantly lower than the control group (t=5.260, 6.912, 6.262, P<0.05). The baseline levels of TNF-α, CRP, PCT and IL-6 in the high altitude group were higher than those in the control group. After treatment, the levels of several inflammation-related factors decreased in both groups, but the high altitude group was still higher than the control group. The expression levels of inflammation-related factors (TNF-α, CRP, IL-6, PCT) in subjects at high altitude were negatively correlated with the levels of lung function related indicators (PEF, FEV1, FVC) (r=-0.453, -0.496, -0.379, -0.563, -0.467, -0.522, -0.497, -0.518, -0.419, -0.416, -0.438, -0.480), and the correlation coefficients were statistically significant (P<0.05). Conclusion High altitude living factors are associated with the decrease of PEF. At the same time, it indirectly aggravates the inflammatory state of patients, and it is more difficult for therapeutic intervention to control the inflammation to the ideal level within the same time, which is worthy of clinical attention.

This paper aims to provide a scientific basis for future research in this area.

Objective To investigate the association of energy metabolic markers with the risk of spontaneous bacterial peritonitis (SBP) in patients with decompensated hepatitis B virus-related liver cirrhosis (HBV-LC). Methods A retrospective analysis was performed for the clinical data of the patients with decompensated HBV-LC who were admitted to Mengchao Hepatobiliary Hospital of Fujian Medical University from November 2017 to November 2019, and baseline clinical parameters and energy metabolic markers were compared between the patients with SBP and those without SBP within 2 weeks after admission. A multivariate logistic regression analysis was performed to investigate the risk factors for SBP. The t -test was used for comparison of normally distributed continuous data between two groups, and the Kruskal-Wallis H test was used for comparison of non-normally distributed continuous data between two groups; the Fisher's exact test was used for comparison of categorical data between two groups. The receiver operating characteristic (ROC) curve was plotted to evaluate the diagnostic efficiency of the newly established logistic regression model, and with the corresponding point of Youden index as the cut-off value, the DeLong test was used to compare the area under the ROC curve (AUC). Results A total of 50 patients with decompensated HBV-LC were included, among whom 23 (46%) developed SBP within 2 weeks after admission and 27 (54%) had no SBP during hospitalization. Compared with the non-SBP patients, the SBP patients had significantly lower triglyceride, prealbumin, and prothrombin time activity (PTA) and significantly higher international normalization ratio, C-reactive protein (CRP), and Model for End-Stage Liver Disease score (all P < 0.05). Comparison of baseline energy metabolic markers showed that compared with the non-SBP patients, the SBP patients had significantly lower respiratory quotient (RQ) [0.79(0.76-0.86) vs 0.85(0.79-0.91), P =0.041] and carbohydrate oxidation (CHO) rate [20.50%(15.25%-41.05%) vs 41.6%(22.25%-68.05%), P =0.041]. The multivariate logistic regression analysis showed that PTA was an independent risk factor for SBP in the patients with decompensated HBV-LC during hospitalization (odd ratio=0.004, P =0.008), and the regression model established based on the variables including PTA, CRP, RQ, and CHO had an AUC of 85.0% and a cut-off value of 0.60 at the maximum Youden index, with a specificity of 85.19% and a sensitivity of 73.91%, suggesting that this model had a better discriminatory ability than CRP (AUC=74.5%, P =0.049) and procalcitonin (AUC=56.4%, P < 0.01). Conclusion There are significant reductions in the energy metabolic markers RQ and CHO in the patients with decompensated HBV-LC who develop SBP within a short term, and their combination with PTA, CRP, and CHO/RQ ratio can help clinicians identify the patients at a high risk of SBP in the early stage and enhance nutrition support for such patients.

OBJECTIVE：To explore the mode of pharmaceutical care for oral medication of tumor patients with dysphagia by clinical pharmacists ，so as to promote clinical rational and safe drug use. METHODS ：Based on typical cases ，the problems existing in the oral medication of tumor patients with dysphagia were analyzed ，and the medication guidance and pharmaceutical care given by clinical pharmacists were expounded. RESULTS ：Clinical pharmacists found that tumor patients with dysphagia had some problems during oral medication ，such as improper administration position ，tube feeding of slow-controlled release preparations after opening the capsule ，limited administration route ，biting cytotoxic drugs ，unknown solubility of targeted drugs ，interaction of multiple drugs. In view of the above problems ，clinical pharmacists assisted physicians and nursing staff to provide pharmaceutical care to patients in combination with the patient ’s disease characteristics ，pharmacy，pharmacokinetics，pharmacodynamics，drug solubility，drug interaction and other factors ，such as skillfully using appropriate drug delivery location and mode ，using local drug delivery mode ，selecting appropriate dosage form based on pharmaceutical knowledge （the characteristics of new dosage form ）， guiding patients to use drugs correctly by being familiar with the characteristics of cytotoxic drugs and targeted drugs ，paying attention to potential drug interactions and guiding nurses to use drugs correctly. The situation of improper medication was improved. CONCLUSIONS ：Clinical pharmacists should participate in clinical therapy actively ，and make appropriate interventions with professional knowledge of pharmacy so as to promote the correct use of oral medication for tumor patients with dysphagia.

Objective To investigate the risk factors for short-term prognosis in patients with HBV-related acute-on-chronic liver failure (ACLF). Methods A retrospective analysis was performed for the clinical data of 119 patients with HBV-related ACLF who were admitted to Mengchao Hepatobiliary Hospital of Fujian Medical University from October 2019 to October 2020, and according to their survival status on day 90, they were divided into death group and survival group. The patients were given antiviral therapy with entecavir or tenofovir. Related clinical data were collected, including alanine aminotransferase (ALT), aspartate aminotransferase, cholinesterase (ChE), albumin (Alb), cholesterol, alpha-fetoprotein, and HBV DNA at baseline, as well as the incidence rate of important complications. Model for End-Stage Liver Disease (MELD) score was also calculated. The t -test or the Mann-Whitney U test was used for comparison of continuous data between two groups, and the chi-squared test was used for comparison of categorical data between two groups; a logistic regression analysis was used to investigate the influencing factors for the 90-day prognosis of patients with HBV-related ACLF and establish a new predictive model; the receiver operating characteristic (ROC) curve was used to evaluate the diagnostic efficiency of the new model in predicting the prognosis of HBV-related ACLF. Results Of all patients, 33 died within 90 days, resulting in a mortality rate of 27.7%. There were significant differences between the survival group and the death group in age, ALT, Alb, ChE, MELD score, and incidence rates of hepatic encephalopathy, primary peritonitis, and hepatorenal syndrome (all P < 0.05). The logistic regression analysis showed that baseline hepatic encephalopathy (odds ratio [ OR ]=10.404, 95% confidence interval [ CI ]: 2.522-42.926, P =0.001), serum Alb at baseline ( OR =0.853, 95% CI : 0.764-0.952, P =0.005), and MELD score at baseline ( OR =1.143, 95% CI : 1.036-1.261, P =0.008) were independent predictive factors for the short-term prognosis of patients with HBV-related ACLF. A new predictive model was established based on the combination of these three indices, and the ROC curve analysis showed that this new model had an area under the curve of 0.833, while MELD score had an area under the ROC curve of 0.672. Conclusion As for the evaluation of the 90-day prognosis of patients with HBV-related ACLF, the new prognostic model established based on hepatic encephalopathy, Alb, and MELD score has a better predictive value than MELD score alone.

Objective:To investigate and analyze the energy metabolism characteristics and the correlation between energy metabolism and the risk of secondary bacterial infection in patients with hepatitis B virus-related chronic liver disease (HBV-CLD).Methods:Data of 183 cases admitted to the Mengchao Hepatobiliary Hospital of Fujian Medical University from November 2017 to November 2020 were retrospectively analyzed. 79 cases of chronic hepatitis B, 51 cases of hepatitis B-related liver cirrhosis, and 53 cases of hepatitis B-related liver failure were collected. Among them patients with liver failure and decompensated liver cirrhosis were defined as severe liver disease group. The Quark RMR indirect calorimetry (COSMED Corporation, Italy) was used to exam the patients' energy metabolism condition, and the incidences of secondary bacterial infection of the patients during hospitalization were recorded. Shapiro-Wilk test and normal QQ plot were used to analyze the normal distribution of continuous variable data, which was consistent with the normal distribution and was described by mean ± standard deviation. In addition, if it did not conform to the normal distribution, the median and interquartile distance were used to describe it. Levene’s test was used to test the homogeneity of variance of the data, which was consistent with the normal distribution. The t-test was used to compare the means of the two groups of samples. One-way analysis of variance was used to compare the mean values of the three groups of samples, and then the Tukey's test was used to compare the two groups. If the variance was uneven or did not conform to the normal distribution, the Wilcoxon rank sum test was used to compare the differences between the two groups. Kruskal-Wallis test (H test) was used to compare the differences between the three groups of samples, and then the Dunnett’s test (Z test) was used for comparison between the two groups. Categorical variable data were analyzed using chi-square test. Logistic regression analysis was used to screen independent risk factors, and the criteria for variable inclusion ( P < 0.05). Results:The respiratory entropy (RQ) and non-protein respiratory entropy (npRQ) of the three groups had statistically significant difference ( P < 0.05). Among them, the RQ and npRQ of the chronic hepatitis B group were higher than hepatitis B-related liver cirrhosis group and hepatitis B-related liver failure group. There were statistically significant differences in fat oxidation rate (FAT%) and carbohydrate oxidation rate (CHO%) between the three groups ( P < 0.05). Compared with hepatitis B-related liver cirrhosis group and hepatitis B-related liver failure group, chronic hepatitis B group ( P < 0.05) had lower FAT% and higher CHO%. There were no statistically significant differences in the measured and predicted resting energy expenditure and protein oxidation rate (PRO%) between the three groups. The incidence of secondary bacterial infection in patients with severe liver disease was 48.39% (45/93). Compared with the non-infected group, the RQ and npRQ values ??of the infected group were significantly decreased ( P < 0.05), while FAT% was significantly increased ( P < 0.05). Logistic regression analysis showed that glutamyltransferase, cholesterol, and npRQ were independent risk factors for secondary bacterial infections in patients with severe liver disease. Glutamyltransferase elevation, and cholesterol and npRQ depletion had suggested an increased risk of secondary bacterial infection. Subgroup analysis of patients with hepatitis B-related liver failure also showed that compared with non-infected group, RQ value and npRQ value of secondary bacterial infection group were significantly decreased ( P < 0.05), while FAT% was significantly increased ( P < 0.05). Conclusion:Patients with hepatitis B virus-related chronic liver disease generally have abnormal energy metabolism. Low RQ, npRQ, CHO% and high FAT% are related to the severity of the disease; while npRQ reduction is related to the risk of secondary bacterial infection in patients with severe liver disease, and thus can be used as a clinical prognostic indicator.

Objective:To investigate the potential mechanism of microRNA (miRNA) in hepatitis B virus (HBV) infection.Methods:The peripheral blood samples were collected from four chronic hepatitis B (CHB) patients who visited Mengchao Hepatobiliary Hospital of Fujian Medical University in 2017, and those were also collected from four healthy controls. Affymetrix GeneChip microRNA 4.0 was applied to detect the expressions of miRNA between CHB patients and healthy controls. The CHB relative differential expressions of miRNA were obtained. The functions of CHB relative miRNA were analyzed by the combination of bioinformatics tools and public database data.Results:A total of seven miRNA were differentially expressed in the peripheral blood of CHB patients. Among them, miRNA-122-5p (log 2 fold change (log 2FC)=7.78, P=0.007 3), let-7c-5p (log 2FC=3.52, P=0.019 6), miRNA-6794-5p (log 2FC=1.15, P=0.033 2), and miRNA-1226-5p (log 2FC=0.68, P=0.034 3) were up-regulated, while miRNA-619-5p (log 2FC=-1.83, P=0.002 6), miRNA-1273g-3p (log 2FC=-2.69, P=0.025 1), and miRNA-4440 (log 2FC=-3.99, P=0.047 8) were down-regulated. Further analysis showed that these miRNA could directly interact with HBV gene sequence and impact the replication of the virus. Among them, miRNA-122-5p, miRNA-6794-5p and miRNA-1226-5p could negatively regulate target genes expression to influence the formation of ficolin-1 rich granule, ficolin-1 rich granule lumen, podosome and membrane ruffle, which participated in the cell membrane movement and cell-matrix adhesion. Conclusion:MiRNA could impact the molecular movement in the cell membrane and facilitate HBV entry to liver cells, playing an important supporting role in HBV infection process.

Objective To explore the relationship of Crohn's disease (CD) susceptibility to aryl hydrocarbon receptor (AhR) polymorphisms and haplotypes in Han population in Wenzhou city, China. Methods A total of 310 CD patients and 573 age-and sex-matched healthy controls were enrolled in our study. Three single nucleotide polymorphisms (SNPs) of AhR(rs10249788,rs2158041,rs2066853) were determined by the improved multiple ligase detection reaction technique. Unconditional logistic regression analyses was applied to analyze the allelic and genotypic differences of each SNP between CD patients and controls, as well as their influence on the clinicopathologic characteristics in CD patients. Analyses of linkage disequilibrium and haplotype were performed by Haploview 4.2 software in all study subjects. Results Compared with the controls, the variant allele (T) and genotype (CT+TT) of (rs2158041) were evidently decreased among CD patients (19.52% vs. 25.04%, P=0.009; 34.19% vs. 44.68%, P=0.003). According to"the Montreal Classification Standards", CD patients were divided into different subgroups. The variant allele(T)and genotype(CT+TT)of(rs2158041)were significantly lower in patients with terminal ileum CD than in controls (16.79% vs. 25.04%, P=0.005; 28.24% vs. 44.68%, P=0.001). Similar conclusions were also drawn in patients with constricting disease when compared with the controls(15.20%vs.25.04%,P=0.003;28.43% vs.44.68%,P=0.003).The three SNPs above were shown to be in a linkage disequilibrium.Compared with the controls respectively,the frequency of haplotype(CCG)was increased in CD patients (44.73% vs. 39.60%, P=0.039), whereas that of haplotype (CTG) was decreased (18.02% vs. 22.78%, P=0.047). Conclusions AhR (rs2158041) variation might influence the risk as well as the location and behavior of CD. The haplotype (CCG) possibly increase the risk of CD development, whereas haplotype(CTG)might decrease it.

OBJECTIVETo assess the association of vascular endothelial growth factor (VEGF) gene polymorphisms with susceptibility to Crohn's disease (CD) in a Chinese population.

METHODSFor 275 CD patients and 495 controls, the genotypes of VEGF gene rs699947 and rs3025039 loci were determined with a SNaPshot method.

RESULTSThe allelic and genotypic frequencies of the rs699947 and rs3025039 loci did not differ between the two groups (all P>0.05). By stratification analysis, allele A and genotype CA+AA of rs699947 were more frequent in patients with colonic CD compared with the controls (P=0.006, 95%CI:1.143-2.234; P=0.005, 95%CI:1.203-2.900, respectively). Compared with the controls, the allele A and genotype CA+AA of rs699947 were less frequent in patients with ileal lesions including ileal CD and ileocolonic CD (P=0.033, 95%CI:0.524-0.974;P=0.043, 95%CI:0.481-0.989, respectively). The frequency of TT homozygote of rs3025039 was lower in patients with non-stricturing and non-penetrating CD compared with the controls (P=0.036, 95%CI:0.016-0.870).

CONCLUSIONPolymorphisms of the VEGF gene rs699947 locus may contribute to an increased risk for colonic CD, but may play a protective role in patients with ileal lesion. Individuals carrying the TT genotype for VEGF rs3025039 locus may be less susceptible to non-stricturing and non-penetrating CD.
