Résumé

Objective To analyze the clinical characteristics and influencing factors of non-small cell lung cancer (NSCLC) patients with chronic obstructive pulmonary disease (COPD) in Hubei province, and to provide a theoretical basis for the diagnosis and treatment of NSCLC patients with COPD. Methods A total of 246 NSCLC patients admitted to our hospital from 2018 to 2020 were selected and divided into control group (without COPD, n=125) and observation group (with COPD, n=121) according to COPD. The clinical characteristics of chest pain, hemoptysis, emasculation, atelectasis and pleural effusion were compared between the two groups. The values of FEV1/FVC, RV/TLC and DLCO in the two groups were measured by pulmonary function detector. The age, gender, smoking, smoking history, proportion of lung squamous cell carcinoma, TNM stage and other clinical data of all subjects were analyzed by self-made survey scale of our hospital. Univariate analysis and logistic regression were used to analyze the risk factors of COPD in NSCLC patients. Results Among 246 NSCLC patients, 121 patients (49.19%) were complicated with COPD, including 76 males and 45 females, and there was a statistical difference between the two groups (χ2=4.891, P>0.05). The average age of the observation group (61.02±4.82) was significantly higher than that of the control group (59.76±4.73) (t=2.069, P0.05). Male (OR=2.982), smoking history (OR=2.623) and lung squamous cell carcinoma (OR=3.147) were risk factors for COPD in NSCLC patients (P<0.05). Conclusions NSCLC patients with COPD are more common in male smokers in Hubei Province, often accompanied by pleural effusion , severe hemoptysis and other symptoms , and their lung function is decreased. Early detection and standardized treatment of COPD in the treatment of NSCLC can improve the prognosis of patients.

Résumé

In this study, we designed and synthesized 12 novel aloperine derivatives with different core structures. Among them, compound 3 with a ten-membered ring core was obtained through a special ring expansion reaction after γ-H Huffman elimination of quaternary ammonium salt, and the structure was verified by X-single crystal diffraction. Furthermore, their antiviral activity against human β-coronavirus HCoV-OC43 was evaluated by CCK-8 assay. Quaternary ammonium salt 2a and 3 had a good inhibitory effect against HCoV-OC43, and 2a had the highest anti-HCoV-OC43 activity with an EC50 values of 3.77 μmol·L-1 and a SI value of over 53.1. Schrӧdinger molecular docking results showed that both 2a and 3 might display their anti-HCoV-OC43 activity by directly acting on host TMPRSS2 and SR-B1. The results expanded the structural types of endocyclic aloperine and the function against coronavirus, and provided useful scientific data for the development of pharmaceutical applications of these compounds.

Résumé

This study investigated the effect of Suanzaoren Decoction on the expression of N-methyl-D-aspartate receptors(NMDAR) and α-amino-3-hydroxy-5-methyl-4-isoxazole-propionic acid receptors(AMPAR) in the hippocampus and synaptic plasticity in rats with conditioned fear-induced anxiety. The effect of Suanzaoren Decoction on rat behaviors were evaluated through open field experiment, elevated plus maze experiment, and light/dark box experiment. Enzyme-linked immunosorbent assay(ELISA) was used to measure the levels of glutamate(Glu) and γ-aminobutyric acid(GABA) in the rat hippocampus. Real-time fluorescence quantitative PCR(qRT-PCR) and Western blot were employed to assess the gene and protein expression of ionotropic glutamate receptors in the hippocampal region. Transmission electron microscopy was utilized to observe the changes in the ultrastructure of synaptic neurons in the hippocampal region. Long-term potentiation(LTP) detection technique was employed to record the changes in population spike(PS) amplitude in the hippocampal region of mice in each group. The behavioral results showed that compared with the model group, the Suanzaoren Decoction group effectively increased the number of entries into open arms, time spent in open arms, percentage of time spent in open arms out of total movement time, number of entries into open arms out of total entries into both arms(P<0.01), and significantly increased the time spent in the light box and the number of shuttle crossings(P<0.01). There was an increasing trend in the number of grid crossings, entries into the center grid, and time spent in the center grid, indicating a significant anxiolytic effect. ELISA results showed that compared with the model group, the Suanzaoren Decoction group exhibited significantly reduced levels of Glu, Glu/GABA ratio(P<0.01), and significantly increased levels of GABA(P<0.01) in the rat hippocampus. Furthermore, Suanzaoren Decoction significantly decreased the gene and protein expression of NMDAR(GluN2B and GluN2A) and AMPAR(GluA1 and GluA2) compared with the model group. Transmission electron microscopy results demonstrated improvements in synapses, neuronal cells, and organelles in the hippocampal region of the Suanzaoren Decoction group compared with the model group. LTP detection results showed a significant increase in the PS amplitude changes in the hippocampal region of Suanzaoren Decoction group from 5 to 35 min compared with the model group(P<0.05, P<0.01). In conclusion, Suanzaoren Decoction exhibits significant anxiolytic effects, which may be attributed to the reduction in NMDAR and AMPAR expression levels and the improvement of synaptic plasticity.

Résumé

OBJECTIVE@#To explore the effect of Xuebijing injection on inflammation in sepsis by regulating intestinal microbiota and its metabolites.@*METHODS@#A total of 45 male Sprague-Dawley (SD) rats were randomly divided into Sham operation group (Sham group), cecal ligation and perforation (CLP) induced sepsis group (CLP group), and Xuebijing intervention group (XBJ group, 4 mL/kg Xuebijing injection was injected intraperitoneally at 1 hour after CLP), with 15 rats in each group. The survival of rats was observed at 24 hours after operation and sacrificed. Feces were collected for 16S rRNA gene sequencing and liquid chromatography-mass spectrometry (LC-MS) analysis.@*RESULTS@#At 24 hours after operation, all rats in the Sham group survived, the mortality of rats in the XBJ group was lower than that in the CLP group [47% (7/15) vs. 60% (9/15), P > 0.05]. Compared with the Sham group, the diversity of gut microbiota in the CLP group decreased, the dominant flora changed, and the abundance of inflammation-related flora increased. Xuebijing improved the changes in gut microbiota caused by sepsis, and α diversity showed an increasing trend (Ace index: 406.0±22.5 vs. 363.2±38.2, Chao1 index: 409.7±21.8 vs. 362.4±42.5, both P > 0.05). Restrictive constrained principal coordinate analysis (cPCoA) showed a high similarity in gut microbiota among the same group of rats. The CLP group was dominated by Bacteroidetes, while the Sham and XBJ groups were dominated by Firmicutes. In addition, compared with the CLP group, Xuebijing treatment increased the abundance of beneficial bacteria in septic rats, such as Verrucomicrobia, Akkermansia and Lactobacillus. LC-MS and orthogonal partial least squares discriminant analysis (OPLS-DA) showed that there were 12 main differential metabolites among the three groups, and there were certain correlations between these metabolites, which were related to amino acid and lipid metabolism. Correlation analysis showed a significant correlation between changes in metabolites and microbial communities.@*CONCLUSIONS@#Xuebijing can improve the survival rate of septic rats, regulate the composition of intestinal flora and related metabolites, which provides a new pathophysiological mechanism for Xuebijing in the treatment of sepsis.

Résumé

Objective:To study the influence of intensive magnet fields on radiation dose measurement, and to demonstrate the feasibility of measuring magnet field correction factor by a combination of medical linac with variable magnet fields in view of needing for accurate measurement of the doses from reference beam arising in MR image-guided radiotherapy.Methods:A photon radiation field and a variable field with 6 MV nominal high voltage were produced by using conventional medical electron linear accelerator equipped with a pair of electromagnets with magnetic field strength up to 1.5 T. Both PTW30013 and PTW31010 ionization chambers were used to test the responses of ionization chambers under different magnetic field strengths at four orientations in which the angles between ionization chamber axis and magnetic field direction were 0°, 180°, 90° and 270°, respectively. The magnetic factors, kB, M was calculated and compared with the reported values in literature. Results:The response of ionization chamber was proportional to the magnetic field strength before it reached to a peak around 1 T, and then fell down as the magnetic field continued to rise. When the magnetic field was 0.35 T, the magnetic factors of PTW31010 were 0.988 2±0.000 3 and 0.997 4±0.000 4 corresponding to 90° and 0° directions, the discrepancy between 0° scenario and literature was 0.05% ± 0.04%. When the magnetic field reached 1.5 T, the magnetic factor of PTW30013 was 0.958 9±0.000 5 at the situation of 90°, which was 0.60% ± 0.05% different from the literature value.Conclusions:Conventional 6 MV medical accelerator equipped with electromagnet can be used to measure the magnetic field factor of reference dosimetry for MRIgRT.

Résumé

Objective:To investigate the efficacy of the classified reduction based on CT two-dimensional images for the surgical treatment of single segment facet joint dislocation in subaxial cervical spine.Methods:A retrospective case series study was made on 105 patients with single segment facet joint dislocation in subaxial cervical spine admitted to Zhengzhou Orthopedic Hospital from January 2015 to October 2022. There were 63 males and 42 females, with the age range of 22-78 years [(47.5±3.6)years]. Preoperative American Spinal Cord Injury Association (ASIA) classification was grade A in 23 patients, grade B in 45, grade C in 22, grade D in 15 and grade E in 0. The classification of surgical approach was based on the presence or not of continuity between anterior and posterior subaxial cervical structures and the movability of the posterior cervical facet joint on CT two-dimensional images, including anterior cervical surgery if both were presented and posterior facet joint resection plus anterior cervical surgery if there was discontinuity between anterior and posterior subaxial cervical structures or posterior facet joint fusion. Reduction procedures were applied in accordance with the type of facet joint dislocation classified based on the position of the lower upper corner of facet joint, including skull traction or manipulative reduction for the dislocation locating at the dorsal side (type A), intraoperative skull traction and leverage technique for the dislocation locating at the top (type B) and intraoperative skull traction and leverage technique with boosting for the dislocation locating at the ventral side (type C). If the dislocation of two facet joints in the same patient was different, the priority of management followed the order of type C, type B and type A. The reduction success rate, operation time and intraoperative blood loss were recorded. The cervical physiological curvature was evaluated by comparing the intervertebral space height and Cobb angle before operation, at 3 months after operation and at the last follow-up. The fusion rate of intervertebral bone grafting was evaluated by Lenke grading at 3 months after operation. The spinal cord nerve injury was assessed with ASIA classification before operation and at 3 months after operation. Japanese Orthopedic Association (JOA) score was applied to measure the degree of cervical spinal cord dysfunction before operation and at 3 months after operation, and the final follow-up score was used to calculate the rate of spinal cord functional recovery. The occurrence of complications was observed.Results:All patients were followed up for 3-9 months [(6.0±2.5)months]. The reduction success rate was 100%. The operation time was 40-95 minutes [(58.6±9.3)minutes]. The intraoperative blood loss was 40 to 120 ml [(55.7±6.8)ml]. The intervertebral space height was (4.7±0.3)mm and (4.7±0.2)mm at 3 months after operation and at the last follow-up, significantly decreased from preoperative (3.1±0.5)mm (all P<0.01), but there was no significant difference in intervertebral space height at 3 months after operation and at the last follow-up ( P>0.05). The Cobb angle was (6.5±1.3)° and (6.3±1.2)° at 3 months after operation and at the last follow-up, significantly increased from preoperative (-5.4±2.2)° (all P<0.01), but there was no significant difference in Cobb angle at 3 months after operation and at the last follow-up ( P>0.05). The fusion rate of intervertebral bone grafting evaluated by Lenke grading was 100% at 3 months after operation. The ASIA grading was grade A in 15 patients, grade B in 42, grade C in 29, grade D in 12 and grade E in 7 at 3 months after operation. The patients showed varying degrees of improvement in postoperative ASIA grade except that 15 patients with preoperative ASIA grade A had partial recovery of limb sensation but no improvement in ASIA grade. The JOA score was (13.3±0.6)points and (13.1±0.6)points at 3 months after operation and at the last follow-up, significantly improved from preoperative (6.8±1.4)points (all P<0.01), but there was no significant difference in JOA score at 3 months after operation and at the last follow-up ( P>0.05). The rate of spinal cord functional recovery was (66.3±2.5)% at the last follow-up. All patients had no complications such as increased nerve damage or vascular damage. Conclusion:The classified reduction based on CT two-dimensional images for the surgical treatment of single segment facet joint dislocation in subaxial cervical spine has advantages of reduced facet joint dislocation, recovered intervertebral space height and physiological curvature, good intervertebral fusion and improved spinal cord function.

Résumé

Objective:To investigate the effects of 40 Hz and 70 Hz frequency flash stimulation on the ability of learning memory and autonomous exploratory in young rats.Methods:Twenty-seven SPF grade male SD rats aged 19-21 days were divided into control group (Ctr group), 40 Hz group and 70 Hz group with 9 in each group according to the random number table.The rats in Ctr group were not given flash stimulation, while rats in the 40 Hz and 70 Hz group were received 40 Hz, 70 Hz flash stimulation (1.5 h/d for 39 days), respectively.The Morris water maze experiment was used to assess the learning and memory ability of rats, and the open field experiment was used to evaluate the ability of autonomous exploratory of rats.Nissl staining was used to assess the morphology of Nissl bodies in the hippocampus CA1 region of the rats.The local field potentials (LFPs) collected from the primary visual cortex (V1 area) region by electrophysiological experiments was used to verify the synchronization of flash evoked neural oscillations.SPSS 23.0 software was used for statistical analysis.The repeated measures ANOVA and one-way ANOVA were used to analyze normal distribution measurement data, and LSD and Tamhane tests were used for further pairwise comparison.The Kruskal-Wallis test was used for non-normal distribution measurement data.Results:(1) The flash stimulation of 40 Hz and 70 Hz both can effectively caused synchronization of neural oscillations in the primary visual cortex of healthy young rats.(2) The results of repeated measures ANOVA analysis showed that there was no interaction effect of grouping and time in the escape latency of young rats in the Morris water maze positioning navigation phase( F=1.326, P>0.05 ). The escape latency had time main effect ( F=40.025, P<0.05), but no grouping main effect ( F=2.039, P>0.05). With the increase of learning days, the escape latency of young rats in each group decreased significantly.There was no interaction effect of grouping and time in the total distance of young rats ( F=2.029, P>0.079). It had time main effect ( F=32.052, P<0.05), but not grouping main effect ( F=2.390, P>0.05) on total distance.With the increase of learning days, the total distance of young rats in each group significantly shortened.On the 6th day of the Morris water maze experiment, there was no statistically significant difference among groups in terms of time in the target quadrant and the number of crossing platforms ( F=2.511, 0.802, both P>0.05). The results of the open field experiment showed that the total distance traveled in the center of young rats in each group was statistically significant ( H=8.935, P<0.05), the total distance traveled in the center in the 70 Hz group (3.80 (2.25, 6.93) m)was significantly longer than that in the 40 Hz group (0.80 (0.72, 1.46) m), P<0.05). The percentage of time spent in the center was statistically significant in the three groups ( H=11.050, P<0.05). Young rats in the 70 Hz group spent significantly higher percentage of time in the center(3.20(2.43, 8.30)) than those in the 40 Hz group (0.95 (0.37, 1.06 ), P<0.05 ). (3) Nissl staining results showed that Nissl bodies in the hippocampal CA1 area of young rats in Ctr, 40 Hz and 70 Hz group were all arranged neatly and tightly, no edema was found in the surrounding stroma, and no obvious inflammatory cell infiltration was found. Conclusion:70 Hz frequency flash stimulation may promote the ability of learning memory and autonomous exploratory of young rats.

Résumé

Objective:To understand the current situation of spiritual nursing needs in elderly patients with primary glaucoma and its influencing factors, and to analyze its relationship with self-perceived burden and perceived social support, so as to provide a theoretical basis for reducing their spiritual distress and pain and meeting their spiritual nursing needs.Methods:A total of 218 elderly patients with primary glaucoma who were hospitalized in the department of ophthalmology of the First Hospital of Jilin University from March to September, 2022 were selected by convenience sampling. They were investigated by using general information questionnaire, the Nurse Spiritual Therapeutics Scale, the Self-Perceived Burden Scale, and the Perceived Social Support Scale. And multiple linear regression was used to analyze the influencing factors of spiritual nursing needs among elderly patients with primary glaucoma.Results:The total score of spiritual nursing needs of elderly patients with primary glaucoma was (30.73 ± 4.85). The highest dimension of item average score was "building a good atmosphere" (3.02 ± 0.59), and the lowest dimension was "helping religious practice" (1.95 ± 0.63). The total scores of spiritual nursing needs and self-perceived burden were negatively correlated ( r=-0.423, P<0.01), and positively correlated with the total scores of perceived social support ( r=0.515, P<0.01). Multivariate linear regression analysis showed that age, religious belief, educational level, treatment duration, residence, self-perceived burden, and perceived social support were the main influencing factors of spiritual care needs of elderly patients with primary glaucoma, ( t values were -5.23-7.04, all P<0.01), which could explain 44.5% of the total variation. Conclusions:The spiritual nursing needs of elderly patients with primary glaucoma were at a medium level. Therefore, it is recommended that nurses should carry out targeted spiritual nursing for them according to the differences and characteristics of different patients, to reduce their self-perceived burden, and to improve perceived social support level, in order to meet their spiritual nursing needs.

Objective: To analyze the occurrence and risk factors of various occupational hazard incidents in China's power grid enterprises. Methods: A total of 4 191 workers from eight power grid enterprises in Jilin Province, Shandong Province, and Chongqing City were selected using a convenience sampling method. Their exposure in workplace and the occurrence of various occupational hazard incidents from 2018 to 2020 were investigated. Results: Among the participants, 71.7% were engaged in outdoor operations. The incidence rates of occupational hazard emergency, ranking from high to low, were electric ophthalmia, acute mountain sickness, heatstroke, electro-flash dermatitis, sunburn, cold injury, solar ophthalmia, and gas poisoning in confined space, with the rate of 42.3%, 42.3%, 38.1%, 24.3%, 17.4%, 16.5%, 10.0%, and 1.3%, respectively (P<0.01). The results of multivariate logistic regression analysis showed that workers in Jilin Province had a higher risk of cold injury compared to those in Shandong Province and Chongqing City (all P<0.01). Workers in Chongqing City had a higher risk of solar ophthalmia than those in Jilin Province (P<0.01). Workers in inspection and maintenance positions had a higher risk of heatstroke and sunburn compared to those in substation positions (all P<0.05). Power grid workers with protective systems in enterprises had a lower risk of sunburn and solar ophthalmia compared to those without protective systems (all P<0.01). The risks of sunburn and solar ophthalmia among power grid workers increased with age and daily outdoor working time (all P<0.05). Taking protective measures was a protective factor against heatstroke and cold injury (all P<0.01). Conclusion: Power grid workers face the risk of various occupational hazard incidents. Relevant organizations should conduct targeted preventive measures based on regional and worker characteristics, and ensure the implementation of protective systems in different work environments.

Résumé

Gastroesophageal reflux disease (GERD) is a frequently and commonly occurring disease in clinic. In recent decades, with the development in pathophysiology and drug researches, modern medicine has achieved remarkable progress and results in diagnosis and treatment. However, the treatments for non-erosive reflux disease, refractory gastroesophageal reflux disease, proton pump inhibitor resistance, overlap of disease symptoms, and extraesophageal symptoms are limited and ineffective. Traditional Chinese medicine (TCM) was widely used in clinical practice, which has been proved effective in relieving symptoms and improving the quality of life. Sponsored by China Association of Chinese Medicine (CACM) and undertaken by the Spleen and Stomach Disease Branch of CACM, "the 12th Youth Salon of Clinical Predominance Disease Series (GERD)" invited 18 authoritative digestive experts of TCM and western medicine to discuss "the difficulties of clinical diagnosis and treatment of GERD and TCM advantages". The focus issues such as modern medical diagnosis and treatment achievements and contributions, improvement and maintenance of symptoms, response to overlapping disease symptoms, reduction and withdrawal of acid suppressors, and treatment of extra-esophageal symptoms were discussed in depth. TCM and western medicine exchanged and complemented each other's strengths, combing the difficulties of modern medical diagnosis and treatment, which clarified the positioning and advantages of TCM and provided guidance for clinical and scientific research.

OBJECTIVE@#To summarize the evaluation methods of return to sports (RTS) after anterior cruciate ligament reconstruction (ACLR) in recent years, in order to provide reference for clinical practice.@*METHODS@#The literature related to the RTS after ACLR was searched from CNKI, Wanfang, PubMed, and Foreign Medical Information Resources Retrieval Platform (FMRS) databases. The retrieval range was from 2010 to 2023, and 66 papers were finally included for review. The relevant literature was summarized and analyzed from the aspects of RTS time, objective evaluation indicators, and psychological evaluation.@*RESULTS@#RTS is the common desire of patients with ACL injury and doctors, as well as the initial intention of selecting surgery. A reasonable and perfect evaluation method of RTS can not only help patients recover to preoperative exercise level, but also protect patients from re-injury. At present, the main criterion for clinical judgement of RTS is time. It is basically agreed that RTS after 9 months can reduce the re-injury. In addition to time, it is also necessary to test the lower limb muscle strength, jumping, balance, and other aspects of the patient, comprehensively assess the degree of functional recovery and determine the different time of RTS according to the type of exercise. Psychological assessment plays an important role in RTS and has a good clinical predictive effect.@*CONCLUSION@#RTS is one of the research hotspots after ACLR. At present, there are many related evaluation methods, which need to be further optimized by more research to build a comprehensive and standardized evaluation system.

Résumé

High-frequency steady-state asymmetric visual evoked potential (SSaVEP) provides a new paradigm for designing comfortable and practical brain-computer interface (BCI) systems. However, due to the weak amplitude and strong noise of high-frequency signals, it is of great significance to study how to enhance their signal features. In this study, a 30 Hz high-frequency visual stimulus was used, and the peripheral visual field was equally divided into eight annular sectors. Eight kinds of annular sector pairs were selected based on the mapping relationship of visual space onto the primary visual cortex (V1), and three phases (in-phase[0º, 0º], anti-phase [0º, 180º], and anti-phase [180º, 0º]) were designed for each annular sector pair to explore response intensity and signal-to-noise ratio under phase modulation. A total of 8 healthy subjects were recruited in the experiment. The results showed that three annular sector pairs exhibited significant differences in SSaVEP features under phase modulation at 30 Hz high-frequency stimulation. And the spatial feature analysis showed that the two types of features of the annular sector pair in the lower visual field were significantly higher than those in the upper visual field. This study further used the filter bank and ensemble task-related component analysis to calculate the classification accuracy of annular sector pairs under three-phase modulations, and the average accuracy was up to 91.5%, which proved that the phase-modulated SSaVEP features could be used to encode high- frequency SSaVEP. In summary, the results of this study provide new ideas for enhancing the features of high-frequency SSaVEP signals and expanding the instruction set of the traditional steady state visual evoked potential paradigm.

Résumé

A moxibustion device with the functions of auricular fumigation moxibustion and heat-sensitive moxibustion is designed. The smoke of the ignited moxa stick is used for the fumigation moxibustion at the external auditory canal, while the heat generated works on Dazhui (GV 14) for heat-sensitive moxibustion. The device consists of five parts, i.e. combustion chamber, smoke pipe, smoke processing chamber, power module and connector. It solves the limitations such as unpleasant experience in treatment, unfavorable temperature control, easy scalding and excessive manual dependence induced by usual fumigation moxibustion and during heat-sensitive moxibustion. This moxibustion device may improve the safety and convenience when delivering the treatment with fumigation moxibustion and heat-sensitive moxibustion, as well as the work efficiency of medical staff.

Résumé

【Objective】 To investigate whether there is a correlation between the differences in ABO blood group distribution in patients with pancreatic cancer, and to evaluate the relative risk. 【Methods】 Patients with pathological diagnosis or discharge diagnosis of pancreatic cancer who underwent ABO blood group typing in our hospital from January 2017 to October 2021 were selected, and the blood group distribution of patients and the correlation were analyzed. 【Results】 There was a statistically significant difference between the pancreatic cancer group and the control group (P<0.05). The study showed that type A may be a relative risk factor for pancreatic cancer patients (χ2=42.44, P<0.001), and type B may play a protective role (χ2=16.28, P<0.01). Significant differences were found in distribution between different gender groups (χ2=64.35, P<0.05). The test results showed that type A may be a risk factor for pancreatic cancer in men (χ2=35.2, OR=1.7, 95%CI=0.59-1.02, P<0.001), and type O may play a protective role in pancreatic cancer(χ2=18.22, OR=0.6, 95%CI=0.25-0.32, P<0.01); type A may be a relative risk factor for female pancreatic cancer patients (χ2=7.06, OR=1.4, 95%CI=0.59-1.02, P<0.001), while type B may play a protective role (χ2=20.32, OR=0.5, 95%CI=0.32-0.43, P<0.01). In pancreatic cancer group, the risk factors of blood type A were higher than those of non-A group, and the protective effect of type B was significantly higher than that of non-B group. 【Conclusion】 The distribution of blood group and relative risk factors in pancreatic cancer patients suggest that A type is predominant; in the population with A blood group, more attention should be paid to early prevention and early treatment, so as to reduce the risk of disease.

Résumé

ObjectiveTo investigate the value of the serum levels of Clusterin and sphingosine 1-phosphate (S1P) in assessing the prognosis of sepsis patients with acute liver injury. MethodsA total of 127 sepsis patients with acute liver injury who were admitted to Lianyungang Hospital, Xuzhou Medical University, from March 2019 to May 2022 were enrolled, and according to their prognosis after 28 days of treatment, they were divided into death group with 35 patients and survival group with 92 patients. The independent-samples t test was used for comparison of continuous data between two groups, and the chi-square test was used for comparison of categorical data between groups. A pearson correlation analysis was used to investigate the correlation. The prognostic value of serum Clusterin and S1P was analyzed by receiver operating characteristic curve. ResultsThere were significant differences between the two groups in the degree of liver injury, Acute Physiology and Chronic Health Evaluation Ⅱ (APACHEⅡ) score, Sequential Organ Failure Assessment (SOFA) score, the presence or absence of acute kidney injury, prothrombin time (PT), international normalized ratio (INR), Child-Pugh class, and C-reactive protein (all P<0.05). The death group had significantly lower serum levels of Clusterin and S1P than the survival group (t=11.094 and 10.390, both P<0.05). The patients with severe liver injury had significantly lower serum levels of Clusterin and S1P than those with mild or moderate liver injury (t=9.825 and 11.418, both P<0.05). The multivariate regression analysis showed that the degree of liver injury (odds ratio [OR]=1.260, 95% confidence interval [CI]: 1.081 — 1.468, P<0.05), APACHEII score (OR=1.031, 95%CI: 1.019 — 1.044, P<0.05), SOFA score (OR=1.066, 95%CI: 1.039 — 1.094, P<0.05), Clusterin (OR=0.899, 95%CI: 0.859 — 0.940, P<0.05), and S1P (OR=0.824, 95%CI: 0.749 — 0.908, P<0.05) were independent risk factors for the prognosis of patients with sepsis. The ROC curve analysis showed that serum Clusterin and S1P used alone or in combination had an area under the ROC curve of 0.864, 0.861, and 0.949, respectively. Serum Clusterin and S1P were significantly negatively correlated with alanine aminotransferase, total bilirubin, PT, and INR in sepsis patients with acute liver injury (all P<0.05). ConclusionThe sepsis patients with acute liver injury who died had significant reductions in serum Clusterin and S1P compared with those who survived, and the levels of Clusterin and S1P are closely associated with the degree of liver injury. The combination of Clusterin and S1P has a good value in predicting the prognosis of sepsis patients with acute liver injury and is expected to become a potential marker for predicting the prognosis of sepsis patients with acute liver injury.

Résumé

ObjectiveTo decipher the mechanism of modified Sanpiantang in the treatment of nitroglycerin-induced migraine in rats. MethodSeventy-two Wistar rats were randomized into the control, model (nitroglycerin, 10 mg·kg-1), positive control (rizatriptan, 0.89 mg·kg-1), and high- (12.96 g·kg-1), medium- (6.48 g·kg-1), and low-dose (3.24 g·kg-1) modified Sanpiantang groups. The rat model of migraine was established by intraperitoneal injection of 10 mg·kg-1 nitroglycerin. The behavioral test was carried out to measure the mechanical pain thresholds (MPT) of the periorbital region and hindpaw after successful modeling. The serum levels of nitric oxide (NO), tumor necrosis factor-α (TNF-α), interferon-γ (IFN-γ), and interleukin-1β (IL-1β) in rats were determined by enzyme-linked immunosorbent assay (ELISA). Immunohistochemistry (IHC) was employed to determine the expression of inducible nitric oxide synthase (iNOS) in the trigeminal nucleus caudalis (TNC). Western blot was employed to determine the protein levels of iNOS and phospho-p38 mitogen-activated protein kinase (p-p38 MAPK) in the TNC. Real-time fluorescence quantitative polymerase chain reaction(Real-time PCR) was performed to measure the mRNA levels of iNOS, p38 MAPK, and IL-1β in the TNC. ResultCompared with the control group, the model group showed decreased MPT (P<0.01), elevated serum levels of NO, TNF-α, IFN-γ, and IL-1β (P<0.01), and up-regulated expression levels of p38 MAPK, iNOS, and IL-1β in the TNC (P<0.05, P<0.01). Compared with the model group, modified Sanpiantang increased the MPT (P<0.05), and the medium-dose group showed the most significant effect (P<0.01). In addition, modified Sanpiantang down-regulated the mRNA levels of iNOS, p38 MAPK, and IL-1β and the protein levels of p-p38 MAPK and iNOS in the TNC of migraine rats (P<0.05, P<0.01) and lowered the serum levels of NO, TNF-α, IFN-γ, and IL-1β (P<0.05, P<0.01). ConclusionModified Sanpiantang may treat migraine by down-regulating the expression of pro-inflammatory factors such as NO, TNF-α, IFN-γ, and IL-1β in the p38 MAPK/iNOS signaling pathway to reduce the neurogenic inflammation.
