Objective To investigate the relationship between stationing years of personnel on an island and their traditional Chinese medicine(TCM)constitution,thus providing a reference for adjusting the health status of stationed personnel,preventing and treating diseases.Methods Based on The Scale of Constitution in Chinese Medicine Questionnaire,TCM constitution of 734 personnel stationed on an island was investigated.Pearson χ2 method was used for data analysis.Results Of the 734 personnel stationed on an island 345(47.0%)were of the balanced constitution type and 389(53.0%)were of the biased constitution types.Among the people with biased constitution types,composite constitution accounted for 80.5%(313 people)and the simple accounted for the rest(19.5%,76 people).The top three types of the biased were dampness heat(15.2%),qi deficiency(14.0%),and yin deficiency(10.7%).The distribution of TCM constitution types was significantly different in terms of stationing years on the island(P<0.05).There was a significant difference in the balanced type and yin deficiency type between people with stationing time≤2 years and>8 years(P<0.05).There was a significant difference in qi deficiency type and qi depression type between people with stationing time≤2 years and>5 years(P<0.05).Compared to people with stationing time≤2 years,significant difference was found in yang deficiency type in people with stationing time ranging from 2 to 5 years and those with>8 years(P<0.05).There were significant differences in the phlegm dampness type,blood stasis type,and specific diathesis type between people with stationing time≤2 years and people with stationing time ranging from>2～5 years and>8 years(P<0.05).There were significant differences in the dampness heat type between people with stationing time≤2 years and people with stationing time ranging from>5～8 years and>8 years,between pepole with stationing time ranging from>2～5 years and people with stationing time>8 years(P<0.05).Conclusion The dampness heat type,qi deficiency type and yin deficiency type are common biased TCM constitution in personnel stationed on islands.The longer the time spent on islands,the greater the possibility of forming biased constitution.

Objective To explore the risk signals of niraparib and provide references for rational and safe clinical medication.Methods Niraparib-related adverse drug events(ADEs)reports from Q1 2017 to Q2 2023 were extracted from the US FDA Adverse Event Reporting System(FAERS)database.Risk signals were identified using the reporting odds ratio(ROR),proportional reporting ratio(PRR),Bayesian confidence propagation neural network(BCPNN),and multi-item gamma Poisson shrinker(MGPS)methods.The Risk signals were described and classified by preferred system organ classes(SOCs)and preferred terms(PTs)from the Medical Dictionary for Regulatory Activities(MedDRA)version 26.1,and the occurrence of niraparib-related ADEs was also analyzed.Results A total of 16,961 ADE reports with niraparib as the primary suspected drug were extracted.Through screening and analysis,32 PTs were identified involving 11 SOCs,which were largely consistent with the information in the drug label.However,suspicious signals not mentioned in the label,including neuropathy peripheral,decreased red blood cell count,reduced hematocrit,dehydration,and hot flashes,require further attention.The median occurrence time was 22 days(IQR 2-98 days),and the Weibull distribution test indicated an early failure-type curve.Conclusion When using niraparib,particularly in early stages of treatment,it is essential to monitor not only the ADEs mentioned in the drug instructions,such as decreased platelet count,nausea and fatigue,but also to pay close attention to the ADEs not included in the instructions,such as peripheral neuropathy and decreased red blood cell count,which exhibit strong signal values,to ensure patient medication safety.

Objective:To explore the relationship between the personality traits and work-family conflict in Chinese adults and examine the roles of social support and self-efficacy in this relationship.Methods:A total of 2 079 working adults were selected and investigated with the Simplified Version of the Big Five Personality Scale(BFI-10),Work Family Conflict Scale(WFCS),Perceived Social Support Scale(PSSS),and General Self Efficacy Scale(GSES).The moderated mediating effect was tested by PROCESS.Results:The neuroticism scores were sig-nificantly positively correlated with the WFCS scores(r=0.11-0.19,P＜0.01),the scores of extraversion,agree-ableness and responsibility were significantly negatively correlated with the WFCS scores(r=-0.06--0.17,Ps＜0.01).The PSSS scores played a partial mediating role between neuroticism,agreeableness,responsibility scores and WFCS scores,the proportions of mediating effect were 17.03％,32.86％and 48.26％.The GSES scores mod-erated the relationship between WFCS scores and other personality traits(β=-0.07-0.04.Ps＜0.05),except for extroverted personality(β=-0.01,P＞0.05).Conclusion:Social support plays a mediating role between the per-sonality traits and work-family conflict,and the mediating effect is moderated by self-efficacy.

Objective:To discuss the protective effect of sodium butyrate(NaB)on acute liver injury in the mice induced by lipopolysaccharide(LPS)combined with D-galactosamine(D-Gal),and to clarify its mechanism.Methods:Thirty male Kunming mice were randomly divided into control group,model group,and NaB group,and there were 10 mice in each group.The mice in NaB group were given 200 mg·kg-1·d-1 NaB,while the mice in control group and model group were given an equal volume of sterile water.The mice in model group and NaB group were intraperitoneally injected with 20 μg·kg-1 LPS and 600 mg·kg-1 D-Gal to induce the acute liver injury models.The body weights and liver weights of the mice in various groups were detcted,and the liver index was calculated.HE staining was used to observe the pathomorphology of liver tissue of the mice in various groups;kits were used to detect the activities of alanine aminotransferase(ALT)and aspartate aminotransferase(AST)in serum,and the activities of total superoxide dismutase(T-SOD)and catalase(CAT),and the levels of malondialdehyde(MDA)in liver tissue of the mice in various groups;Western blotting method was used to detect the expression levels of nuclear factor E2-related factor 2(Nrf2)and heme oxygenase-1(HO-1)proteins in liver tissue of the mice in various groups.Results:There were no significant differences in body weights of the mice among various groups(P>0.05).Compared with control group,the liver index of the mice in model group was significantly increased(P<0.01).Compared with model group,the liver index of the mice in NaB group was significantly decreased(P<0.01).The HE staining results showed that the liver tissue of the mice in control group exhibited normal structure,with clear boundaries of hepatocytes,consistent size,radially arranged around the central vein,and the nucleus located in the center of the cells;in model group,the arrangement of hepatocytes was disordered,the cells were swollen,there were multiple foci of hepatocellular necrosis,inflammatory cell infiltration,and hemorrhage;compared with model group,the cells in NaB group showed improved hepatocellular structure and reduced inflammatory infiltration.Compared with control group,the activities of ALT and AST in serum of the mice in model group were significantly increased(P<0.01);compared with model group,the activities of ALT and AST in serum of the mice in NaB group were significantly decreased(P<0.05 or P<0.01).Compared with control group,the activities of T-SOD and CAT in liver tissue of the mice in model group were significantly decreased(P<0.01),and the level of MDA was significantly increased(P<0.01);compared with model group,the activities of T-SOD and CAT in liver tissue of the mice in NaB group were significantly increased(P<0.05 or P<0.01),and the level of MDA was significantly decreased(P<0.01).The Western blotting results showed that compared with control group,the expression levels of Nrf2 and HO-1 proteins in liver tissue of the mice in model group were significantly decreased(P<0.05);compared with model group,the expression levels of Nrf2 and HO-1 proteins in liver tissue of the mice in NaB group were significantly increased(P<0.01).Conclusion:NaB has a protective effect on LPS/D-Gal induced acute liver injury in the mice,and its mechanism may be related to the upregulation of the expressions of Nrf2 and HO-1 proteins and the increas of the activity of oxidant enzyme in liver tissue by NaB,thereby reduces the liver oxidative stress level of liver.

AIM: To explore the mechanism of action of alkaloid components of compound kushen Injection (CKI) in the treatment of lung cancer based on serum metabolomics, network pharmacology, and molecular docking techniques. METHODS: A lung cancer model was established in C57 mice by inoculation of Lewis mouse lung cancer tumor strain. Thirty male mice were randomly divided into normal group, model group and CKI group. The drug was administered by tail vein injection once daily for 17 consecutive days. Mouse serum was examined by ultrahigh performance liquid chromatography tandem mass spectrometry (LC-MS) metabolomics, and several multivariate statistical analyses including principal component analysis (PCA) and orthogonal partial least squares discriminant analysis (OPLS-DA), combined with databases such as the human metabolic database (HMDB) and related literature to identify and identify differential metabolites, the relevant metabolic pathways were searched for by the metaboanalyst online tool. Using network pharmacology, construct the“component-target-disease”network of CKI in the treatment of lung cancer. Molecular docking method was used to verify the interaction between potential active ingredients and core targets. Serum metabolomics was jointly analyzed with network pharmacology to construct a“metabolite-germinal-enzyme-gene” network. RESULTS: Through metabolomics technology, 16 differential metabolites associated with lung cancer were screened from serum, and CKI addback these differential metabolite levels compared with the model group. Metabolic pathways mainly involve retinol metabolism, tryptophan metabolism, glycerophospholipid metabolism and other metabolic pathways. Network pharmacology analysis indicated that CKI treatment of lung cancer mainly targets STAT3, MAPK3, and MAPK1, which are closely related to proteoglycans, cellular senescence, and HIF − 1 signaling pathways in cancer. CONCLUSION: This article explains the mechanism of CKI in treating lung cancer from the perspective of metabonomics and network pharmacology, and provides basis for further study of CKI.

Objective:To observe the changes of neutrophil to lymphocyte ratio and lung function of patients defined by different TCM syndromes with acute exacerbation of chronic obstructive pulmonary disease.Methods:A total of 181 patients with acute exacerbation of chronic obstructive pulmonary disease in our hospital from January 2016 to Novenber 2018 were included and divided into 5 groups accoding to different TCM syndromes, which were wind-cold invading lung syndrome (26), external cold and internal fluid syndrome (40), phlegm-heat obstructing lung syndrome (48), phlegm-dampness blocked syndrome (48), an heart spirit confused by phlegm syndrome (19). Then tested the blood for each group, and calculated NLR; tested c-reactive protein, and lung function, and measured with COPD Assessment Test (CAT) and Modified British Medical Research Council (mMRC); conducted 6MWT, then the BODE index and Charlson Comorbidity Index (CCI) scores were calculated.Results:The NLR, CRP level in patients with external cold and internal fluid syndrome and an heart spirit confused by phlegm syndromeby phlegm were significantly higher than those of other syndrome ( P<0.05 or P<0.01), and FEV1% Pred was significantly lower than that of phlegm-dampness blocked syndrome ( P=0.024); the 6-minute walking distance of patients with external cold and internal fluid syndrome was significantly shorter than that of phlegm-heat obstructing lung syndrome and phlegm-dampness blocked syndrome ( P=0.006, P=0.024). The comparison of mMRC grades among the syndromes was statistically significant ( F=26.367, P=0.049). The BODE index of patients external cold and internal fluid syndrome was higher than that of patients phlegm-heat obstructing lung syndrome ( P=0.015), and the CCI score of patients an heart spirit confused by phlegm syndrome was higher than that of patients phlegm-dampness blocked syndrome ( P=0.012). The BODE index of patients with external cold internal fluid syndrome was significantly higher than that of phlegm-heat obstructing lung syndrome ( P=0.015). The CCI score of patients with mental disorder caused by phlegm was significantly higher than that of phlegm-dampness blocked lung syndrome ( P=0.012). Conclusions:There were significantly differences in neutrophil to lymphocyte ratio, CRP and 6-minute walking distance among different TCM syndromes in patients with acute exacerbation of chronic obstructive pulmonary disease. The inflammation in patients with external cold and internal fluid syndrome and mental disorder caused by phlegmare much severe, but there might be no difference in dyspnea and prognosis among TCM syndromes.

A 64-year-old female patient with endometrial cancer received an IV infusion of dexamethasone sodium phosphate injection 10 mg dissolved in 5% glucose injection 100 ml before chemotherapy to prevent allergic reaction induced by paclitaxel. The infusion was finished within about 30 minutes and the patient had no discomfort during the infusion. About 2 hours later, the patient developed urinary incontinence without urgent and painful urination, which gradually disappeared. Two hours after the second intravenous infusion of dexamethasone sodium phosphate injection, urinary incontinence recurred. After the intravenous infusion of dexamethasone sodium phosphate injection was replaced by oral dexamethasone tablets, the symptoms of urinary incontinence were alleviated. It was considered that the temporary urinary incontinence was probably related to dexamethasone sodium phosphate.
